At Western Digital, we believe in the promise of data. Everywhere data is captured, preserved, accessed and transformed—we are leading the charge to unlock its potential, enabling the technologies and solutions that shape our lives. We are an industry leading provider of data storage solutions, employing a global workforce focused on delivering the possibilities of data. Our Brands Western Digital has an unmatched depth and breadth of technologies, storage devices, systems and solutions that offer us unique ways to innovate that no one else in the industry can. Our Western Digital products and solutions portfolio offer data- centric solutions that meet the performance, reliability, scalability and TCO needs of commercial and enterprise markets, and enable both businesses and individuals to capture, preserve, access and transform an ever-growing volume of data. Our data-centric solutions are marketed under the Western Digital, SanDisk, WD and G-Technology brands. A Message from the CEO Dear Fellow Shareholders, Fiscal 2018 was an outstanding year for Western Digital. Over the past year we experienced strong financial performance while continuing to make progress on the transformation of Western Digital into the world’s leading provider of solutions to capture, preserve, access and transform data. We have built a platform for long-term growth and leadership, and are well positioned to address the breadth of Big Data and Fast Data needs with an increasing range of purpose-built technologies and architectures. We will continue to take an active role in shaping the future trends as the market continues to evolve and grow. In fiscal 2018 we grew revenue to $21 billion, representing growth of 8% from the prior year and at the high end of our long-term target revenue growth range of 4% to 8%. Demand for our hard drive and flash products was strong across our end markets resulting in revenue growth in both categories. Non-GAAP gross margin expanded nearly 5 points to a record 42.5% driven by a higher revenue mix of capacity enterprise hard drives and flash. With just a 2% increase in non-GAAP operating expenses, we generated a 38% improvement in non-GAAP operating income, reflecting the significant operating leverage in our business model. Non-GAAP earnings per share grew 60% from the prior year to $14.73 setting a significant milestone.1 Stephen D. Milligan Chief Executive Officer Western Digital Corporation Reflecting solid execution supported by healthy demand for our products, operating cash flow increased 22% from the prior year to $4.2 billion. We invested $1.6 billion in our business, primarily in the flash joint venture, resulting in fiscal year 2018 free cash flow of $2.7 billion. We continued to optimize our debt structure resulting in lower interest expenses and an improved credit rating enabling us to accelerate our shareholder return initiatives via share repurchases. We made further progress on several key operational initiatives outlined previously towards continued value creation: • Continued to unleash the power of our platform. The various components that comprise this platform, including technologies, products, go-to-market capabilities, and our team, are helping us better serve our diversified customer base and an expanding set of end markets, and manage our business to the best strategic and financial outcomes. Simply put, the power of our platform allows us to allocate resources and capital to particular businesses and products based on market supply/demand and customer needs. • Leadership in capacity enterprise helium HDDs. We began shipping our fifth-generation platform at 14 terabyte capacities to global customers in both established and emerging markets. On a cumulative basis, since the launch of our industry-leading helium platform, we have shipped more than 30 million drives, reflecting strong customer preference and adoption of our offering. The significant penetration of our helium platform underscores our multi-generational leadership position in this category. • Leadership in 3D flash and multi-level cell technologies. We launched BiCS4, our 96-layer technology, an industry first, and will be implementing it across our product portfolio spanning consumer, mobile, computing and data center end markets. Our 3D flash will also feature four- bits-per-cell architecture, a technology that we pioneered, and we believe that over time, four-bits-per-cell technology will find mainstream use in all end markets. Our deep expertise in silicon processing, device engineering and system integration capabilities positions us to provide differentiated storage solutions for our customers. 1 Reconciliations of the differences between the foregoing non-GAAP financial measures and free cash flow to the comparable GAAP financial measures can be found on the last page of this document. Fiscal 2017 and much of fiscal 2018 was characterized by tight demand-supply dynamics in flash. In the past few quarters, however, flash demand-supply conditions have been in a normalization phase. Further, a softer than expected demand environment in key sectors such as mobility, is causing temporary imbalances in the demand-supply environment causing flash pricing to decline at a rate faster than we experienced previously. We are responding to the changing market environment and we are in discussions with our JV partner to appropriately adjust our capital investment plans with the objective to align our supply growth with market needs. For the first time since we acquired SanDisk, Western Digital has been navigating the normalizing flash environment. We are managing our business in these dynamic conditions well with our portfolio of hard drive and flash products. The soft flash environment will constrain our near-term financial performance, but the long-term capabilities of our business and value of our platform remain as strong as ever. To ensure that our positioning gets continuously stronger, we are: • Expanding our portfolio further to support growth in data and to derive value from it • Investing in 3D flash, microwave assisted magnetic recording and related systems level capabilities to ensure our technology leadership position • Re-aligning our hard drive manufacturing footprint with market requirements • Focused on operational execution to deliver value for our customers and other stakeholders Combined with a deepening engagement with our diversified customer base, the Western Digital platform remains on a path to deliver long-term earnings that we believe will exceed the record- setting fiscal 2018 levels. In closing, I thank our employees for their hard work and dedication. We continue to grow and innovate at a rapid pace, and our talented team has been there every step of the way to help us execute and lead the industry forward. We are also grateful for the ongoing support from our customers, partners and shareholders.

We expect to develop and commercialize additional generations of 3D NAND technologies over the next several years while continuing to utilize our older technology for certain markets and applications. We are leveraging our expertise, resources and strategic investments in non-volatile memories to explore a wide spectrum of persistent memory and storage class memory technologies. We have also initiated, defined and developed standards to meet new market needs and to promote wide acceptance of flash storage standards through interoperability and ease-of-use. Our products generally leverage a common platform for various products within product families, and in some cases across product families, resulting in the commonality of components which reduces our exposure to changes in demand, facilitates inventory management and allows us to achieve lower costs through purchasing economies. This platform strategy also enables our customers to leverage their qualification efforts onto successive product models. For a discussion of associated risks, see Part I, Item 1A, Risk Factors, of this Annual Report on Form 10-K. 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. R&D expenses totaled $2.40 billion, $2.44 billion and $1.63 billion in 2018, 2017 and 2016, respectively. For a discussion of associated risks, see Part I, Item 1A, Risk Factors, of this Annual Report on Form 10-K. Patents, Licenses and Proprietary Information We rely on a combination of patents, trademarks, copyright and trade secret laws, confidentiality procedures and licensing arrangements to protect our IP rights. We have more than 14,000 active patents worldwide and have many patent applications in process. We continually seek additional United States (‘‘U.S.’’) and international patents on our technology. We believe that, although our active patents and patent applications have considerable value, the successful manufacturing and marketing of our products also depends upon the technical and managerial competence of our staff. Accordingly, the patents held and applied for cannot alone ensure our future success. In addition to patent protection of certain IP rights, we consider elements of our product designs and processes to be proprietary and confidential. We believe that our non-patented IP, particularly some of our process technology, is an important factor in our success. We rely upon non-disclosure agreements, 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 laws of 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 IP portfolio to compete successfully in the storage industry. For a discussion of associated risks, see Part I, Item 1A, Risk Factors, 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, human resources and training to continue to be successful and to grow our manufacturing operations as necessary. We strive to maintain manufacturing flexibility, high manufacturing yields, reliable products and high-quality components. The critical elements of our production of HDD and flash-based products are high-volume and utilization, low-cost assembly 7 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. We continually monitor our manufacturing capabilities to respond to the changing requirements of our customers and maintain our competitiveness and position as a data technology leader. HDD and flash-based product manufacturing are complex processes involving the production and assembly of precision components with narrow tolerances and rigorous 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. 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. Substantially all of our flash-based supply requirements for our flash-based products is obtained from our business ventures with TMC, which provide us with leading-edge, high-quality and low-cost flash-based memory wafers. This represents a captive supply and we are obligated to take our share of the output from these ventures or pay the fixed costs associated with that capacity. See ‘‘Ventures with Toshiba Memory’’ below for additional information. While substantially all of our flash memory supply utilized for our products is purchased from these ventures, from time-to-time, we also purchase flash memory from other flash-based manufacturers, which we refer to as non-captive. While we do not unilaterally control the operations of these ventures, we believe that our business venture relationship with TMC helps us to reduce the costs of producing our products, increases our ability to control the quality of our products and speeds delivery of our products to our customers. Our vertically integrated manufacturing operations for our flash-based products are concentrated in three locations, with our business ventures with TMC located in Yokkaichi, Japan, and our in-house assembly and test operations located in Shanghai, China and Penang, Malaysia. We also leverage the efficiencies of contract manufacturers when strategically advantageous. For a discussion of associated risks, see Part I, Item 1A, Risk Factors, of this Annual Report on Form 10-K. Materials and Supplies HDD primarily consists of recording heads, magnetic media and a printed circuit board assembly. We design and manufacture substantially all of the recording heads and magnetic media required for our products. As a result, we are more dependent upon our own development and execution efforts and less reliant on recording 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. Our flash-based product consists of flash-based memory and controllers. Substantially all of our flash-based memory is supplied by our business ventures with TMC. Controllers are primarily designed in-house and manufactured by third-party foundries or acquired from third-party suppliers. We believe the use of our in-house assembly and test facilities, as well as contract manufacturers, provides flexibility and gives us access to increased production capacity. We have developed deep relationships with these vendors and TMC to establish continuous supply of flash-based memory and controllers. We generally retain multiple suppliers for our component requirements but in some instances use sole or single sources for business or technology reasons. Currently, we believe that there are no major issues with component availability. For a discussion of associated risks, see Part I, Item 1A, Risk Factors, of this Annual Report on Form 10-K. Ventures with Toshiba Memory We and TMC currently operate three business ventures in 300-millimeter flash-based manufacturing facilities in Yokkaichi, Japan, which provide us leading-edge, cost-competitive flash-based memory wafers for our end products. Through Flash Partners Ltd., Flash Alliance Ltd., and Flash Forward Ltd., which we collectively refer to as Flash Ventures, we and TMC collaborate in the development and manufacture of flash-based memory wafers using semiconductor manufacturing equipment owned or leased by each of the Flash Venture entities. We hold a 49.9% ownership position in each of the Flash Venture entities. Each Flash Venture entity purchases wafers from TMC at cost and then resells those wafers to us and TMC at cost plus a mark-up. We are obligated to purchase half of Flash Ventures’ flash-based memory wafer supply or pay for half of Flash Ventures’ fixed costs regardless of the output we choose to purchase. We are also obligated to fund 49.9% to 50% of Flash Ventures’ investments to the extent that Flash Ventures’ operating cash flow is insufficient to fund these investments. We and TMC also collaborate on certain R&D activities in support of Flash Ventures. 8 The agreements governing the operations of the Flash Venture entities also set out a framework for any investment by the joint venture partners in NAND manufacturing capacity. Flash Ventures’ manufacturing site in Yokkaichi, Japan is owned and operated by TMC and includes five wafer fabrication facilities, the newest of which are known as ‘‘New Fab 2’’ and ‘‘Fab 6.’’ The primary purpose of New Fab 2 and Fab 6 is to provide clean room space to support the continued conversion of existing 2-dimensional (‘‘2D’’) NAND wafer capacity to 3D NAND. We have jointly invested, and intend to continue to jointly invest, with TMC in manufacturing equipment for these facilities. In addition, TMC has announced that it is starting construction of a new wafer fabrication facility for the manufacture of 3D NAND in Kitakami, Iwate, Japan. Pursuant to our agreements governing Flash Ventures, which give us priority to participate in expansions and conversions of NAND manufacturing capacity, we intend to jointly invest with TMC in manufacturing equipment at the new facility in Kitakami, based on our ongoing discussions with TMC. On June 1, 2018, TMC, formerly a wholly owned subsidiary of Toshiba Corporation, was purchased by a consortium led by Bain Capital (the ‘‘Bain Consortium’’) that includes SK hynix Inc. and other competitors, as well as key customers. For a discussion of risks associated with our business ventures with TMC, see Part I, Item 1A, Risk Factors, 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 U.S. companies but do not include sales to U.S. subsidiaries of foreign companies, represented 78%, 80% and 72% of our net revenue for 2018, 2017 and 2016, 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 of associated risks, see Part I, Item 1A, Risk Factors, 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 by providing information and support through our website. 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. While these groups of customers make up our end markets, some of these customers cross into multiple groups. We define these customers as follows: Original Equipment Manufacturers. OEMs, including large-scale data center operators, system integrators and cloud customers who bundle, embed, or integrate our storage solutions, 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 sell directly to cloud infrastructure players as well as flash storage solutions to customers that offer our products under their own brand name in the retail market, which we also classify as OEMs. Distributors. We use a broad group of distributors to sell our products to non-direct customers such as small computer and consumer electronics (‘‘CE’’) manufacturers, dealers, value-added resellers, 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 websites. For each of 2018, 2017 and 2016, no single customer accounted for 10% or more of our net revenue. For a discussion of associated risks, see Part I, Item 1A, Risk Factors, of this Annual Report on Form 10-K. For additional information 9 regarding revenue recognition, sales by geographic region and major customers, see Part II, Item 8, Note 1, Organization and Basis of Presentation and Note 10, Business Segment, Geographic Information and Concentration of Risk, of 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 60 days of the placement of the order. Customers’ purchase orders 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 Part I, Item 1A, Risk Factors, 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 sale depending on the type of product, with a small number of products having a warranty ranging up to ten years or more. 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 additional information regarding our service and warranty policy, see Part II, Item 8, Note 1, Organization and Basis of Presentation, 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 clean-up 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 Part I, Item 1A, Risk Factors, of this Annual Report on Form 10-K. Employees As of June 29, 2018, we employed a total of approximately 71,600 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 that we believe are, in the aggregate, competitive with those offered by our competitors. 10 While the substantial majority of our employees are not party to a collective bargaining agreement, a majority of our employees in Japan and China are subject to collective bargaining agreements. We consider our employee relations to be good. For a discussion of associated risks, see Part I, Item 1A, Risk Factors, of this Annual Report on Form 10-K. Corporate Responsibility and Sustainability We are committed to growing our company in a strong and sustainable way and fostering a sustainable future for the communities we serve. We believe that corporate social responsibility is an essential factor for our overall success. This includes adopting ethical and sustainable practices to direct how we do business while keeping the interests of our stakeholders and the environment in mind, including valuing and challenging the talented men and women who comprise our workforce, and investing in and improving the communities where we live and work. Our practices and policies underscore this commitment: • We treat all employees with dignity and respect and foster diversity and inclusion globally. • We establish processes and policies for our employees to uphold ethical standards and comply with applicable laws and our internal guidelines, including a Code of Business Ethics adopted by our Board of Directors and applicable to members of our Board of Directors and all employees, a Global Code of Conduct applicable to all employees and an actively-managed ethics hotline. • We establish policies and procedures intended to promote the idea that the quality of our products and services, consistency of production and employee well-being are predicated on a safe and healthy work environment. • We establish policies and processes intended to promote environmental responsibility as an integral part of our culture, and we publish an environmental report detailing emissions output and set goals to reduce our greenhouse gas emissions and electronic waste profile. • We engage with local communities across the globe, focusing on science, technology, engineering and math (targeting underrepresented and underprivileged youth), hunger relief, and environmental quality.

Item 1A. Risk Factors Our business, financial condition and operating results can be affected by a number of risks and uncertainties, whether currently known or unknown, any one or more of which could, directly or indirectly, cause our actual results of operations and financial condition to vary materially from past, or from anticipated future, results of operations and financial condition. The risks and uncertainties discussed below are not the only ones facing our business, but do represent those risks and uncertainties that we believe are material to us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also adversely affect our business, financial condition, results of operations or the market price of our common stock. 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 equity, credit and other financial markets and 11 real estate markets, slower growth in certain geographic regions, lower levels of consumer liquidity, risk of default on sovereign debt, higher interest rates, materials and component cost increases, political uncertainty and other macroeconomic factors, such as the trade and tariff actions recently announced by the U.S., China and other countries, and changes to policies, rules and regulations. Some of the risks and uncertainties we face as a result of these conditions include, but are not limited to, the following: • Our direct and indirect customers may delay or reduce their purchases of our products and systems containing our products. • 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. • We extend credit and payment terms to some of our customers and we could suffer significant losses if a customer whose accounts receivable we have not insured, or have underinsured, fails to pay us on their accounts receivable balances. • If negative or uncertain global economic conditions result in circumstances, such as a sustained decline in our stock price and market capitalization or a decrease in our forecasted cash flows, indicating that the carrying value of our long-lived assets or goodwill may be impaired, we could be required to record a significant charge to earnings in our Consolidated Financial Statements. These actions and conditions could result in reductions in our revenue, increased operating costs, impairment charges and other expenses, which could adversely affect our business, results of operations and financial condition. We rely substantially on our business ventures with Toshiba Memory Corporation (‘‘TMC’’) for the supply of flash-based memory and the development of flash-based technology, which subjects us to risks and uncertainties that could harm our business, financial condition and operating results. We are dependent on our ventures with TMC to develop and manufacture flash-based memory products for our flash-based memory supply, and therefore our business, financial condition and operating results are dependent on the continued success of Flash Ventures. We partner with TMC on the development of flash-based technology, including the next technology transitions of flash-based memory, as well as other non-volatile memory technology in support of Flash Ventures. Flash Ventures is subject to various risks that could harm the value of our investments, our revenue and costs, our future rate of spending, our technology plans and our future growth opportunities. Substantially all of our flash-based memory is supplied by Flash Ventures, which limits our ability to respond to market demand and supply changes. A failure to accurately forecast demand could cause us to over-invest or under-invest in technology transitions or the expansion of captive memory capacity in Flash Ventures. Over-investment could result in excess supply, which could cause significant decreases in our product prices, significant excess, obsolete inventory or inventory write-downs or under-utilization charges, and the potential impairment of our investments in Flash Ventures. On the other hand, if we or TMC under-invest in captive memory capacity or technology transitions, if we grow capacity more slowly than the rest of the industry, if our technology transitions do not occur on the timeline that we expect, if we encounter unanticipated difficulties in implementing these transitions, or if we implement technology transitions more slowly than our competitors, we may not have enough captive supply of the right type of memory or at all to meet demand on a timely and cost effective basis and we may lose opportunities for revenue, gross margin and market share as a result. If our flash-based memory supply is limited, we may make strategic decisions with respect to the allocation of our supply among our products and customers, and these strategic allocation decisions may result in less favorable gross margin or damage certain customer relationships. We are also contractually obligated to pay for 50% of the fixed costs of Flash Ventures regardless of whether we purchase any wafers from Flash Ventures. Furthermore, purchase orders placed with Flash Ventures and under the foundry arrangements with TMC for up to three months are binding and cannot be canceled. Therefore, once our purchase decisions have been made, our production costs for flash memory are fixed, and we may be unable to reduce costs to match any subsequent declines in pricing or demand, which would harm our gross margin. Our limited ability to react to fluctuations in flash memory supply and demand makes our financial results particularly susceptible to variations from our forecasts and expectations. 12 Under the terms of our venture agreements with TMC, which govern the operations of Flash Ventures, we have limited power to unilaterally direct most of the activities that most significantly impact Flash Ventures’ performance and we have limits to our ability to source or fabricate flash-based products outside of the Flash Ventures. We may not always agree with TMC on our joint R&D roadmap or expansions or conversions of production capacity. In addition, TMC’s shift in strategic priorities could adversely impact our business. On June 1, 2018, Toshiba Corporation announced it had completed the sale of TMC, including its interests in Flash Ventures, to a consortium led by SK hynix Inc. and Bain Capital (the ‘‘Bain Consortium’’) that includes other competitors, as well as key customers. The sale of TMC to the Bain Consortium could lead to delays in decision-making, disputes, or changes in strategic direction that could adversely impact Flash Ventures and/or adversely affect our business prospects, results of operations and financial condition. The Bain Consortium might not have the same interest that we do in protecting and growing Flash Ventures’ business and there may exist conflicts of interest between the Bain Consortium and Flash Ventures or us. Misalignment between us and TMC or the Bain Consortium on the strategic direction of Flash Ventures could adversely impact Flash Ventures’ ability to stay at the forefront of technological advancement and/or our investment in Flash Ventures. Flash Ventures’ competitiveness and/or our investment in Flash Ventures could also be harmed by a mishandling or misuse of IP or other competitively sensitive confidential information regarding Flash Ventures, such as its technology roadmap, business or investment plans, by a third party that might gain access to such information. Flash Ventures requires significant investments by both TMC and us for technology transitions, including the transition to 3D NAND, and capacity expansions. The Bain Consortium has entered into financing agreements in connection with its purchase of TMC that could limit TMC’s ability to timely fund or finance investments in Flash Ventures or our joint development efforts, as well as limit Flash Ventures’ ability to enter into lease financings. To the extent that lease financings for Flash Ventures are not accessible on favorable terms or at all, more cash would be required to fund investments. If TMC does not or we do not provide sufficient resources, or have adequate access to credit, to timely fund investments in Flash Ventures, our investments could be delayed or reduced. Delayed or reduced investment in manufacturing capacity or research and development by TMC or us could harm Flash Ventures’ competitiveness and/or our investment in Flash Ventures. In addition, the financing arrangements that the Bain Consortium has entered into in connection with its purchase of TMC are secured by TMC’s equity interests in Flash Ventures, permitting the lenders to foreclose on those equity interests under certain circumstances. TMC has announced that it is starting construction of a new wafer fabrication facility for the manufacture of 3D NAND in Kitakami, Iwate, Japan. Although we intend to enter into agreements with TMC in due course to participate in the new Kitakami facility, there is no certainty as to when, and on what terms, we will do so. If we are unable to extend our partnership with TMC to the Kitakami facility on favorable terms, our future supply of captive flash-based memory could be adversely impacted, which could adversely affect our long-term business and financial results. We participate in a highly competitive industry that is subject to volatile demand, declining average selling prices (‘‘ASPs’’), rapid technological change and industry consolidation, all of which could adversely affect our operating results and financial condition. 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 (including personal computers (‘‘PCs’’) and mobile devices) 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. The prices of our products are influenced by, among other factors, the balance between supply and demand, including the effects of new fab capacity in the industry, macroeconomic factors, business conditions, technology transitions, and other actions taken by us or our competitors. The price of NAND flash memory is also influenced by conversion of industry DRAM capacity to NAND and conversion of 2D NAND capacity to 3D NAND. The storage market has experienced periods of excess capacity, which can lead to liquidation of excess inventories and significant reductions in price. If these price changes occur unnecessarily or in an unexpected manner, there will likely be an adverse impact on our 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 may be able to gain a technological or cost structure advantage over us, which may allow their products to be less costly or enable them to provide better performance or to include additional features when compared to our products. Further, some of our competitors may utilize certain pricing strategies, including offering products at prices at or below cost, that we may be unable to competitively match. In addition, the Chinese government and various agencies, state-owned or 13 affiliated enterprises and investment funds are making significant investments to promote China’s domestic semiconductor industry consistent with the government’s stated national policy objectives. If we are unable to effectively compete with any manufacturers located in China or non-Chinese competitors benefitting from alliances with Chinese companies in the markets where we compete, our operating results and financial condition will suffer. Additionally, some of our competitors offer products and technologies that we do not offer and may be able to use their broader product and technology portfolio to win sales from us. 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. Further, we face potential gross margin pressures resulting from our ASPs declining more rapidly than our cost of goods sold. Rapid technological changes often reduce the volume and profitability of sales of existing products and increase the risk of inventory obsolescence. Finally, the data storage industry as a whole has experienced consolidation over the past several years through acquisitions, mergers and decisions by industry players to exit the industry. Further consolidation across the industry could enhance the capacity, abilities and resources and lower the cost structure of some of our competitors, causing us to be at a competitive disadvantage. These factors, along with others, may also result in significant shifts in market share among the industry’s major participants, including a substantial decrease in our market share, all of which could adversely impact our operating results and financial condition. Expansion into new markets may increase the complexity of our business and cause us to increase our R&D expenses and investments in manufacturing capability, technology enhancements and go-to-market capability, 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 broader range of storage products to our customers. As we expand our product lines to sell into new markets, the overall complexity of our business may increase at an accelerated rate and we may become subject to different market dynamics. These dynamics may include, among other things, different demand volume, cyclicality, seasonality, product requirements, sales channels, and warranty and return policies. In addition, expansion into new markets may result in increases in R&D expenses and substantial investments in manufacturing capability, technology enhancements and go-to-market capability. 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. 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 that we must anticipate and adapt our products to address in a timely manner. If we fail to implement 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 or keep pace with ASP reduction, which could harm our operating results. For example, in transitioning our 2D NAND manufacturing capacity to 3D NAND technology, we could experience delays or other challenges in the production ramp, qualification of wafers, shipment of samples to customers or customer approval process. 3D NAND and any new manufacturing node may be more susceptible to manufacturing yield issues. Manufacturing yield issues may not be identified during the development or production process or solved until an actual product is manufactured and tested, further increasing our costs. If our technology transitions, including the production ramp of 3D NAND technology, take longer, are more costly to complete than anticipated, or do not improve manufacturing yield or other manufacturing efficiencies, our flash memory costs may not remain competitive with other flash-based memory producers or may not fall commensurate with declines in the price of flash-based memory, which would harm revenues, our gross margin and operating results. For additional technology transition risks related to 3D NAND, see the risk factors entitled ‘‘We rely substantially on our business ventures with Toshiba Memory Corporation (‘‘TMC’’) for the supply of flash-based memory and the development of flash-based technology, which subjects us to risks and uncertainties that could harm our business, financial condition and operating results’’ and ‘‘Our strategic relationships subject us to risks that could adversely affect our business, financial condition and results of operations.’’ With respect to HDDs, we announced that we will use microwave-assisted magnetic recording (MAMR) technology to increase HDD capacities. If our HDD technology transitions, including the production ramp of MAMR HDDs, take longer or are more costly to complete than anticipated or if we otherwise fail to implement new HDD technologies successfully, we may not remain competitive with other HDD producers, which could adversely affect our revenues, our gross margin and operating results. 14 Moving to new technologies may require us to align to, and build, a new supply base. Our success in new product areas may be dependent in part on our ability to develop close relationships with new suppliers and on our ability to enter into favorable supply agreements. Where this cannot be done, our business and operations may be adversely affected. In addition, if our customers choose to delay transition to new technologies, if demand for the products that we develop is lower than expected or if the supporting technologies to implement these new technologies are not available, we may be unable to achieve the cost structure required to support our profit objectives or may be unable to grow or maintain our market position. The substitution or replacement of our technologies and products by new technologies could make our products obsolete and harm our operating results. Given the pace of technological development, there is a possibility that new technologies could substitute for or replace our current technologies and products and make them obsolete. Historically, when the industry experiences a fundamental change in storage technologies or standards, any manufacturer that fails to successfully and timely adjust its designs and processes to accommodate or manufacture the new technology or standard fails to remain competitive. There are some revolutionary technologies that, if implemented by a competitor on a commercially viable basis ahead of the industry, could put us at a competitive disadvantage, including shingled magnetic recording, energy-assisted magnetic recording, patterned magnetic media and advanced signal processing. Many companies, including some of our competitors, have also developed or are attempting to develop alternative non-volatile technologies, including non-NAND technologies such as magnetoresistive random-access memory (MRAM), resistive random-access memory (ReRAM) and phase change memory (PCM), and NAND-based vertical or stacked 3D memories based on charge trap, floating gate and other cell architectures. In addition, a provider of processors and non-volatile memory solutions may be developing a new standard to attach ultra-low latency non-volatile memory to its processor memory bus, which it may choose not to license to its competitors, resulting in it being a single source provider of such non-volatile memory solutions. As a result of these shifts in technology and standards, we could incur substantial costs in developing new technologies, such as recording heads, magnetic media and tools, in adopting new standards or in investing in different capital equipment or manufacturing processes to remain competitive. If we fail to successfully implement these new technologies or standards, or if we are significantly slower than our competitors at implementing new technologies or standards, we may not be able to offer products with capacities and capabilities 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. 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 and compete with alternative storage technologies. If our products fail to offer a superior value proposition to alternative storage products, we will be at a competitive disadvantage and our business will suffer. As we introduce new products, standards or technologies, it can take time for these new standards or technologies to be adopted, for customers to accept and transition to these new standards or technologies and for significant sales to be generated, if at all. Failure of our customers to adopt our new products, standards or technologies could harm our results of operations as we fail to reap the benefits of our investments. 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; • our ability to successfully transition future core, processor and controller development to the RISC-V architecture; • market acceptance/qualification; • effective management of inventory levels in line with anticipated product demand; • our ability to respond to customer requests for new products and software associated with our products; • our ability to incorporate open source software elements into our products and operate in an open source environment; 15 • 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; • our ability to increase our software development capability; and • the effectiveness of our go-to-market capability in selling new products. Our strategic relationships subject us to risks that could adversely affect our business, financial condition and results of operations. We have entered into strategic relationships with various partners for future product development, sales growth and the supply of technologies, components, equipment and materials for use in our product design and manufacturing, including our partnership with TMC for flash-based memory development and manufacturing. See the risk factor entitled ‘‘Because we are dependent on a limited number of qualified suppliers, a disruption in our supply chain, including a shortage in supply or a supplier’s failure to support us in a timely manner with goods or services at a quality level and cost acceptable to us, or supplier consolidation, could adversely affect our margins, revenues and operating results’’ for a further description of the risks associated with our reliance on external suppliers. These strategic relationships are subject to various risks that could adversely affect the value of our investments and our results of operations and financial condition. These risks include, but are not limited to, the following: • our interests could diverge from our partners’ interests or we may not agree with co-venturers on ongoing activities, technology transitions or on the amount, timing or nature of further investments in the relationship; • we may experience difficulties and delays in product and technology development at, ramping production at, and transferring technology to, our business ventures; • our control over the operations of our business ventures is limited; • due to financial constraints, our co-venturers may be unable to meet their commitments to us or may pose credit risks for our transactions with them; • due to differing business models, financial constraints or long-term business goals, our partners may decide not to join us in funding capital investment by our business ventures, which may result in higher levels of cash expenditures by us or prevent us from proceeding in the investment; • we may lose the rights to technology or products being developed by the strategic relationship, including if any of our co-venturers is acquired by another company or otherwise transfers its interest in the business venture, files for bankruptcy or experiences financial or other losses; • a bankruptcy event involving a co-venturer could result in the early termination or adverse modification of the business venture or agreements governing the business venture; • we may experience difficulties or delays in collecting amounts due to us from our co-venturers; • the terms of our arrangements may turn out to be unfavorable; and • changes in tax, legal or regulatory requirements may necessitate changes in the agreements with our co-venturers. If our strategic relationships are unsuccessful or there are unanticipated changes in, or termination of, our strategic relationships, our business, results of operations and financial condition may be adversely affected. Because we are dependent on a limited number of qualified suppliers, a disruption in our supply chain, including a shortage in supply or a supplier’s failure to support us in a timely manner with goods or services at a quality level and cost acceptable to us, or supplier consolidation, could adversely affect our margins, revenues and operating results. We depend on an external supply base for technologies, software (including firmware), preamps, controller, components, equipment and materials for use in our product design and manufacturing. We also depend on suppliers for a portion of our wafer testing, chip assembly, product assembly and product testing, and on service suppliers for providing technical support for our products. In addition, we use logistics partners to manage our 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 the components and much of the equipment we acquire must be specifically designed to be compatible for use in our products 16 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. From time to time, our suppliers have experienced difficulty meeting our requirements. If we are unable to purchase sufficient quantities from our current suppliers or qualify and engage additional suppliers, we may not be able to meet demand for our products. Delays or cost increases experienced by our suppliers in developing or sourcing materials and components for use in our products or incompatibility or quality issues relating to our products, could also harm our financial results as well as business relationships with our customers. We do not have long-term contracts with some of our existing suppliers, nor do we always have guaranteed manufacturing capacity with our suppliers and, therefore, we cannot guarantee that they will devote sufficient resources or capacity to manufacturing our products. Any significant problems that occur at our suppliers, or their failure to perform at the level we expect, could lead to product shortages or quality assurance problems, either of which would harm our operating results and financial condition. In addition, if we are unable to purchase sufficient quantities from our current suppliers, we may not be able to engage alternative suppliers who are able or willing to provide goods or services in sufficient quantities or at a cost acceptable to us. In addition, our supply base has experienced industry consolidation. Our suppliers may be acquired by our competitors, consolidate, decide to exit the industry, or redirect their investments and increase costs to us, each of which may have an adverse effect on our business and operations. In addition, some of our suppliers have experienced a decline in financial performance. Where we rely on a limited number of suppliers or a single supplier, the risk of supplier loss due to industry consolidation or a decline in financial performance is enhanced. Some of our suppliers may also be competitors in other areas of our business, which could lead to difficulties in price negotiations or meeting our supply requirements. Any disruption in our supply chain could reduce our revenue and adversely impact our financial results. See the risk factors entitled ‘‘We rely substantially on our business ventures with Toshiba Memory Corporation (‘‘TMC’’) for the supply of flash-based memory and the development of flash-based technology, which subjects us to risks and uncertainties that could harm our business, financial condition and operating results’’ and ‘‘Our strategic relationships subject us to risks that could adversely affect our business, financial condition and results of operations’’ for additional risks related to our supply of flash memory and our strategic relationships. Price volatility, shortages of critical materials or components, or use by other industries of materials and components used in the storage industry, or contractual commitments we enter into with suppliers to reduce the risk of component shortages, could increase our costs and 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, flash-based memory and multi-layer ceramic capacitors (MLCC), 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 (such as the recently announced trade and tariff actions), 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. 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 17 significant cash advances to the supplier; however, these commitments may not result in a satisfactory increase or stabilization of the supply of such components and may cause us to have inadequate or excess component inventory, which could increase our operating costs and adversely affect our operating results. 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, including employees from acquisitions, 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 may be at a competitive disadvantage for retaining and hiring key management, staff and skilled employees versus other companies that may pay a relatively higher portion of 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. 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 throughout Asia. The current concentration of Flash Ventures in Yokkaichi, Japan, magnifies the risks of supply disruption. The facilities of many of our customers, our suppliers and our customers’ suppliers are also concentrated in certain geographic locations throughout Asia and elsewhere. A fire, flood, earthquake, tsunami or other natural disaster, condition or event such as a power outage, political instability, civil unrest, localized labor unrest or other employment issues, or a localized health risk that adversely affects any of these facilities or the employees or logistics operators at these facilities, 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. In addition, the geographic concentration of our manufacturing sites could exacerbate the negative impacts resulting from any of these problems. 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. We may incur losses beyond the limits of, or outside the scope of, the coverage of our insurance policies. There can be no assurance that in the future we will be able to maintain existing insurance coverage or that premiums will not increase substantially. Due to market availability, pricing or other reasons, we may elect not to purchase insurance coverage or to purchase only limited coverage. We maintain limited insurance coverage and, in some cases, no coverage at all, for natural disasters and environmental damages, as these types of insurance are sometimes not available or available only at a prohibitive cost. We depend upon TMC to obtain and maintain sufficient property, business interruption and other insurance for Flash Ventures. If TMC fails to do so, we could suffer significant unreimbursable losses, and such failure could also cause Flash Ventures to breach various financing covenants. 18 Manufacturing, marketing and selling our products globally subjects us to numerous risks. Currently, a large portion of our revenue is derived from our international operations, and many of our products and components are produced overseas. Our revenue and future growth is significantly dependent on the growth of international markets, and we may face difficulties in entering or maintaining international sales markets. We are subject to risks associated with our global manufacturing operations and global marketing and sales efforts, as well as risks associated with our utilization of and reliance on contract manufacturers, including: • obtaining requisite governmental permits and approvals, compliance with foreign laws and regulations, changes in foreign laws and regulations; • the need to comply with regulations on international business, including the Foreign Corrupt Practices Act, the United Kingdom Bribery Act 2010, the anti-bribery laws of other countries and rules regarding conflict minerals; • currency exchange rate fluctuations or restrictions; • political and economic instability, civil unrest and natural disasters; • 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, such as export bans, embargos, sanctions and license and certification requirements (including on encryption technology), new or increased tariffs and fees and complex customs regulations; • 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; • weaker protection of IP rights; • difficulties in managing international operations, including appropriate internal controls; and • loss or non-renewal of favorable tax treatment under agreements or treaties with foreign tax authorities. As a result of these risks, our business, results of operations or financial condition could be adversely affected. Some of these risks, such as trade restrictions, higher tariffs and fees, import and export restrictions or loss of favorable tax treatment under agreements or treaties with foreign tax authorities, could increase as a result of changes to policies, rules and regulations. For example, beginning in early 2018, the U.S. commenced certain trade actions, including proposed new and increased tariffs on an evolving list of imported materials and products. Countries have responded to these actions in various ways, including proposed tariff increases on products imported from the U.S. We cannot predict whether, or to what extent, there may be changes to international trade agreements or whether tariffs or other restrictions may be changed or imposed on our products or our supply chain. Such tariffs, policy or regulatory changes or other trade restrictions could increase our cost of doing business, our ability to sell to certain customers, and our operating results and financial condition could be adversely affected. We experience sales seasonality and cyclicality, which could cause our operating results to fluctuate. Sales of computer systems, mobile devices, storage subsystems, gaming consoles and consumer electronics tend to be seasonal and cyclical, and therefore we expect to continue to experience seasonality and cyclicality in our business as we respond to variations in our customers’ demand for 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. 19 If we fail to identify, manage, complete and integrate acquisitions, investment opportunities or other significant transactions, which are a key part of our growth strategy, it may adversely affect our future results. We seek to be an industry-leading developer, manufacturer and provider of innovative storage solutions, balancing our core hard drive and flash memory business with growing investments in newer areas that we believe will provide us with higher growth opportunities. Acquisitions of, investment opportunities in, or other significant transactions with companies that are complementary to our business are a key part of our overall business strategy. 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. We are also subject to certain covenants in our debt agreements that place limits on our ability to complete acquisitions and investments. 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 or changes in technology development and related roadmaps following 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. Acquisitions and investments may also result in the issuance of equity securities that may be dilutive to our shareholders and the issuance of additional indebtedness that would put additional pressure on liquidity. Furthermore, we may agree to provide continuing service obligations or enter into other agreements in order to obtain certain regulatory approvals of our corporate transactions, and failure to satisfy these additional obligations could result in our failing to obtain regulatory approvals or the imposition of additional obligations on us, any of which could adversely affect our business, financial condition and results of operations. In addition, new legislation or additional regulations may affect or impair our ability to invest with or in certain other countries or require us to obtain regulatory approvals to do so, including investments in joint ventures, minority investments and outbound technology transfers to certain countries Any cost savings initiatives or restructurings that we undertake may not deliver the results we expect, which may adversely affect our business. From time to time, we engage in cost savings initiatives and restructurings that may result in workforce reduction and consolidation of our manufacturing or other facilities. As a result of any cost savings initiatives or restructurings, we may experience a loss of continuity, loss of accumulated knowledge, disruptions to our operations and inefficiency during transitional periods. These actions could also impact employee retention. In addition, we cannot be sure that these actions will be as successful in reducing our overall expenses as we expect or that additional costs will not offset any such reductions or consolidations. If our operating costs are higher than we expect or if we do not maintain adequate control of our costs and expenses, our operating results could be adversely affected. Changes in demand for our products, changes in product life cycles and the failure to qualify our products and achieve design wins with our customers could adversely affect our sales, margins, ASPs and our ability to recover the cost of product development. Events or circumstances that impact demand in the markets for our products, or our inability to address that demand successfully, could materially adversely impact our operating results. For example, demand for our products may be affected by, among other factors, the following: • inconsistent demand from customers whose sales are correlated to large projects and expansions which can be sporadic; • internal customer development of storage solutions; • developments in the regulation and enforcement of digital rights management; • emergence of new technologies; • volatility in demand due to differing patterns of technology adoption and innovation; or • concerns about data protection by end users. 20 If we are not able to respond to these or other events or circumstances that impact demand for our products, it could lead to our customers’ storage needs being satisfied by competing storage technologies, thereby decreasing our sales. As a result, even with increasing aggregate demand for digital storage, if we fail to anticipate or timely respond to the demand for storage, our sales, ASPs and gross margin could decline, which could adversely affect our operating results and financial condition. Product life cycles may lengthen or shorten, both of which could adversely affect gross margins or our ability to recover the cost of product development. We regularly engage in new product qualification with our customers, and the product qualification process may be lengthy for some 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 or lost sales to that customer until the next generation of products is introduced. Even if our products meet customer specifications, our sales to these customers are dependent upon the customers choosing our products over those of our competitors and purchasing our products in sufficient volume, our ability to supply our products in sufficient quantity and in a timely manner and, with respect to OEM partners, the OEMs’ ability to create, market and successfully sell products containing our solutions. Our high level of debt may have an adverse impact on our liquidity, restrict our current and future operations, particularly our ability to respond to business opportunities, and increase our vulnerability to adverse economic and industry conditions. As of June 29, 2018, our total indebtedness was $11.38 billion in aggregate principal, and we had $1.75 billion of additional borrowing availability under our revolving credit facility. Our high level of debt could have significant consequences, which include, but are not limited to, the following: • limiting our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions or other general corporate purposes; • requiring a substantial portion of our cash flows to be dedicated to debt service payments instead of other purposes, thereby reducing the amount of cash flows available for working capital, capital expenditures, acquisitions, R&D and other general corporate purposes; • imposing financial and other restrictive covenants on our operations, including limiting our ability to (i) declare or pay dividends or repurchase shares of our common stock; (ii) purchase assets, make investments, complete acquisitions, consolidate or merge with or into, or sell all or substantially all of our assets to, another person; (iii) dispose of assets; (iv) incur liens; and (v) enter into transactions with affiliates; • placing us at a competitive disadvantage to competitors carrying less debt; and • making us more vulnerable to economic downturns and limiting our ability to withstand competitive pressures or take advantage of new opportunities to grow our business. Our ability to meet the debt service obligations contained in our debt agreements will depend on our available cash and our future performance, which will be affected by financial, business, economic and other factors. Our bank debt also contains a variable interest rate component based on our corporate credit ratings, which could result in increased interest rates and debt service obligations if our ratings were to decline. If we are unable to meet our debt service obligations or should we fail to comply with our financial and other restrictive covenants contained in the agreements governing our indebtedness, causing an event of default under the applicable indebtedness, the debt holders could accelerate the related debt and that may result in the cross-acceleration or cross-default of other debt, leases or other obligations. If we are required to repay our indebtedness before the applicable due dates, we may not have sufficient funds available and we may be required to refinance all or part of our debt, sell important strategic assets at unfavorable prices, incur additional indebtedness or issue common stock or other equity securities, which we may be unable to do on terms acceptable to us, in amounts sufficient to meet our needs or at all. Our inability to service our debt obligations or refinance our debt could have a material adverse effect on our business, operating results and financial condition. Further, if we are unable to repay, refinance or restructure our secured indebtedness, the holder of such debt could proceed against the collateral securing that indebtedness. Refinancing our indebtedness may also require us to expense previous debt issuance costs or to incur new debt issuance costs. 21 In addition to our credit ratings impacting the interest rate on our current debt, our ratings impact the cost and availability of future borrowings and, accordingly, our cost of capital. Our ratings reflect the opinions of the ratings agencies of our financial strength, operating performance and ability to meet our debt obligations. There can be no assurance that we will achieve a particular rating or maintain a particular rating in the future. We may from time to time seek to further refinance our substantial indebtedness by issuing additional shares of our common stock in one or more securities offerings. These securities offerings may dilute our existing shareholders, reduce the value of our common stock, or both. Because our decision to issue securities will depend on, among other things, market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of any future securities offerings. Thus, holders of our common stock bear the risk of our future offerings diluting and potentially reducing the value of our common stock. Changes in tax laws could increase our worldwide tax rate and materially affect our financial position and results of operations. On December 22, 2017, the President of the United States of America signed the Tax Cuts and Jobs Act (the ‘‘2017 Act’’), which includes a broad range of tax reform proposals affecting businesses, including a reduction in the U.S. federal corporate tax rate from 35% to 21%, a one-time mandatory deemed repatriation tax on earnings of certain foreign subsidiaries that were previously tax deferred, and a new minimum tax on certain foreign earnings. The 2017 Act significantly impacts our effective tax rate for fiscal year 2018 as a result of the deemed repatriation tax and may impact several other elements of our operating model. In future years, certain additional provisions of the 2017 Act, such as the minimum tax on certain foreign earnings, will also apply to us and, as a result, we generally expect our effective tax rate to increase from the fiscal year 2018 rate (excluding the mandatory deemed repatriation tax and the re-measurement of deferred taxes). Taxes due over a period of time as a result of the 2017 Act could be accelerated upon certain triggering events, including failure to pay such taxes when due. The 2017 Act makes broad and complex changes to the U.S. tax code and we expect to see future regulatory, administrative or legislative guidance. We are analyzing the 2017 Act to determine the full impact of the new tax law, and to the extent any future guidance differs from our preliminary interpretation of the law, it could have a material effect on our financial position and results of operations. In addition, many countries in the European Union and around the globe have adopted and/or proposed changes to current tax laws. Further, organizations such as the Organization for Economic Cooperation and Development, have published action plans that, if adopted by countries where we do business, could increase our tax obligations in these countries. Due to the large scale of our U.S. and international business activities, many of these enacted and proposed changes to the taxation of our activities could increase our worldwide effective tax rate and harm our financial position and results of operations. 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, or may be terminated if certain conditions are not met. Although many of these holidays may be extended when certain conditions are met, we may not be able to meet such conditions. 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. From time to time we may become subject to income tax examinations 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 U.S. 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 a statutory notice of deficiency seeking certain adjustments to income as disclosed in Part II, Item 8, Note 13, Income Tax Expense (Benefit), of 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. 22 If our technology infrastructure, systems or products are compromised, damaged or interrupted by cyber attacks, data security breaches, other security problems, security vulnerabilities or design defects, or sustain system failures, our operating results and financial condition could be adversely affected. We experience cyber attacks of varying degrees on our technology infrastructure and systems and, as a result, unauthorized parties have obtained in the past, and may in the future obtain, access to our computer systems and networks, including cloud-based platforms. The technology infrastructure and systems of our suppliers, vendors, service providers, cloud solution providers and partners may also experience such attacks. Cyber attacks can include computer viruses, computer denial-of-service attacks, worms, and other malicious software programs or other attacks, covert introduction of malware to computers and networks, impersonation of authorized users, and efforts to discover and exploit any design flaws, bugs, security vulnerabilities or security weaknesses, as well as intentional or unintentional acts by employees or other insiders with access privileges, intentional acts of vandalism by third parties and sabotage. In some instances, efforts to correct vulnerabilities or prevent attacks may reduce the performance of our computer systems and networks, which could negatively impact our business. We believe cyber attack attempts are increasing in number and that cyber attackers are developing increasingly sophisticated systems and means to not only attack systems, but also to evade detection or to obscure their activities. Our products are also targets for cyber attacks, including those products utilized in cloud-based environments as well as our cloud service offerings. While some of our products contain encryption or security algorithms to protect third-party content or user-generated data stored on our products, these products could still be hacked or the encryption schemes could be compromised, breached, or circumvented by motivated and sophisticated attackers. We have agreed with certain customers and strategic partners, including TMC, to undertake certain commitments to promote information security, and we may be liable to TMC or such other parties if we fail to meet our cyber security commitments. In addition, our technology infrastructure and systems are vulnerable to damage or interruption from natural disasters, power loss and telecommunications failures. Further, our products contain sophisticated hardware and operating system software and applications that may contain security problems, security vulnerabilities, or defects in design or manufacture, including ‘‘bugs’’ and other problems that could interfere with the intended operation of our products. If efforts to breach our infrastructure, systems or products are successful or we are unable to protect against these risks, we could suffer interruptions, delays, or cessation of operations of our systems, and loss or misuse of proprietary or confidential information, IP, or sensitive or personal information. Breaches of our infrastructure, systems or products could also cause our customers and other affected third parties to suffer loss or misuse of proprietary or confidential information, IP, or sensitive or personal information, and could harm our relationships with customers and other third parties. As a result, we could experience additional costs, indemnification claims, litigation, and damage to our brand and reputation. All of these consequences could harm our reputation and our business and materially and adversely affect our operating results and financial condition. Sales in the distribution channel and to the retail market are important to our business, and if we fail to respond to demand changes within these markets, or maintain and grow our applicable market share, 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. Negative changes in the credit-worthiness or the ability to access credit, or the bankruptcy or shutdown of any of our significant retail or distribution partners would harm our revenue and our ability to collect outstanding receivable balances. A significant portion of our sales is also made through retailers. 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 retail market channels. Particularly in the retail market, adverse publicity, whether or not justified, or allegations of product or service quality issues, even if false or unfounded, could damage our reputation and cause our customers to choose products offered by our competitors. If customers no longer maintain a preference for our product brands or if our retailers are not successful in selling our products, our operating results may be adversely affected. 23 Loss of market share with or by a key customer, or consolidation among our customer base, could harm our operating results. During the year ended June 29, 2018, 42% of our revenue came from sales to our top 10 customers. These customers have a variety of suppliers to choose from and therefore can make substantial demands on us, including demands on product pricing and on contractual terms, 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 and financial condition 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. Consolidation among our customer base may also lead to reduced demand for our products, increased customer pressure on our prices, 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 mobile, 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 and financial condition could be harmed. We make significant investments in R&D to improve our technology and develop new technologies, and unsuccessful investments or investments that are not cost effective could materially adversely affect our business, financial condition and results of operations. We make significant R&D investments to maintain our existing products and to lead innovation and development of new technologies. In addition, we may increase our capital expenditures and expenses above our historical run-rate model in order to remain competitive. The challenges of reducing operating costs could result in more costly capital expenditures that reduce the cost benefits of technology transitions and could limit our ability to keep pace with reductions in ASPs. Our R&D investments may not result in viable technologies or products, and even if they do result in viable technologies or products, they may not be profitable or accepted by the market. In addition, if we are not able to improve our technology or develop new technologies at the same rate as our competitors or at a rate that is expected by our customers, we may be required to incur additional costs 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. Significant investments in unsuccessful or cost-ineffective R&D 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. We are subject to risks related to product defects or the unintended use or security breaches 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, litigation or indemnification claims. 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, our testing may fail to reveal defects in our products that 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. As part of a product recall, we may be required or choose 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, product defects, product recalls or epidemic failures may cause damage to our reputation or customer relationships, lost 24 revenue, indemnification for a recall of our customers’ products, warranty claims, litigation or loss of market share with our customers, including our OEM and original design manufacturers (‘‘ODM’’) customers. Our business liability insurance may be inadequate or future coverage may be unavailable on acceptable terms, which could adversely impact our operating results and financial condition. 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. Certain of our products contain encryption or security algorithms to protect third party content and user-generated data stored on our products. To the extent our products are hacked or the encryption schemes are compromised or breached, this could harm our business by hurting our reputation, requiring us to employ additional resources to fix the errors or defects and expose us to litigation and indemnification claims. 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, security vulnerabilities or performance issues and subject us to liability. We and certain of our officers are at times involved in litigation, investigations and governmental proceedings, which may be costly, may divert the efforts of our key personnel and could result in adverse court rulings, fines or penalties, which could materially harm our business. We are involved in litigation, including cases involving our IP rights and those of others, antitrust and commercial matters, putative securities class action suits and other actions. We are the plaintiff in some of these actions and the defendant in others. Some of the actions seek injunctive relief, including injunctions against the sale of our products, and substantial monetary damages, which if granted or awarded, could materially harm our business, financial condition and operating results. From time to time, we may also be the subject of inquiries, requests for information, investigations and actions by government and regulatory agencies regarding our businesses. Any such matters could result in material adverse consequences to our results of operations, financial condition or ability to conduct our business, including fines, penalties or restrictions on our business activities. Litigation is subject to inherent risks and uncertainties that may cause actual results to differ materially from our expectations. In the event of an adverse outcome in any litigation, investigation or governmental proceeding, we could be required to pay substantial damages, fines or penalties and cease certain practices or activities, including the manufacture, use and sale of products. With or without merit, such matters can be complex, can extend for a protracted period of time, can be very expensive and the expense can be unpredictable. Litigation initiated by us could also result in counter-claims against us, which could increase the costs associated with the litigation and result in our payment of damages or other judgments against us. In addition, litigation, investigations or governmental proceedings and any related publicity may divert the efforts and attention of some of our key personnel and may also harm the market prices of our securities. We may be obligated to indemnify our current or former directors or employees, or former directors or employees of companies that we have acquired, in connection with litigation, investigations or governmental proceedings. These liabilities could be substantial and may include, among other things: the costs of defending lawsuits against these individuals; the cost of defending shareholder derivative suits; the cost of governmental, law enforcement or regulatory investigations or proceedings; civil or criminal fines and penalties; legal and other expenses; and expenses associated with the remedial measures, if any, which may be imposed. 25 We are subject to laws, rules, and regulations in the U.S. and other countries relating to the collection, use, sharing, and security of third-party data including personal data, and our failure to comply with these laws, rules and regulations could subject us to proceedings by governmental entities or others and cause us to incur penalties, significant legal liability, or loss of customers, loss of revenue, and reputational harm. We are subject to laws, rules, and regulations in the U.S. and other countries relating to the collection, use, and security of third-party data including data that relates to or identifies an individual person. In many cases, these laws apply not only to third-party transactions, but also to transfers of information between us and our subsidiaries, and among us, our subsidiaries and other parties with which we have commercial relations. Our possession and use of third-party data, including personal data and employee data in conducting our business subjects us to legal and regulatory burdens that may require us to notify vendors, customers or employees or other parties with which we have commercial relations of a data security breach and to respond to regulatory inquiries and to enforcement proceedings. Global privacy and data protection legislation, enforcement, and policy activity in this area are rapidly expanding and evolving, and may be inconsistent from jurisdiction to jurisdiction. Compliance requirements and even our inadvertent failure to comply with applicable laws may cause us to incur substantial costs, subject us to proceedings by governmental entities or others, and cause us to incur penalties or other significant legal liability, or lead us to change our business practices. The nature of our industry and its reliance on IP and other proprietary information subjects us and our suppliers, customers and partners to the risk of significant litigation. The data storage industry has been characterized by significant litigation. This includes litigation relating to patent and other IP rights, product liability claims and other types of litigation. We have historically been involved in frequent disputes regarding patent and other IP rights, and we have in the past received, and we may in the future receive, communications from third parties asserting that certain of our products, processes or technologies infringe upon their patent rights, copyrights, trademark rights or other IP rights. We may also receive claims of potential infringement if we attempt to license IP to others. IP risks increase when we enter into new markets where we have little or no IP protection as a defense against litigation. The complexity of the technology involved and the uncertainty of IP litigation increase the IP risks we face. 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 be subject to injunctions, 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. If we incorporate third-party technology into our products or if claims or actions are asserted against us for alleged infringement of the IP of others, 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. We evaluate notices of alleged patent infringement and notices of patents from patent holders that we receive from time to time. 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, customers and partners are subject to similar risks of litigation, and a material, adverse ruling against a supplier, customer or partner could negatively impact our business. Moreover, from time to time, we agree to indemnify certain of our suppliers and customers for alleged IP infringement. The scope of such indemnity varies but may include indemnification for direct and consequential damages and expenses, including attorneys’ fees. We may be engaged in litigation as a result of these indemnification obligations. Third party claims for patent infringement are excluded from coverage under our insurance policies. A future obligation to indemnify our customers or suppliers may harm our business, financial condition and operating results. Our reliance on IP 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 IP such as our process technology. We primarily rely on patent, copyright, trademark and trade secret laws, as well as nondisclosure agreements and other methods, to protect our proprietary technologies and processes. There can be no assurance that our existing patents will continue to be held valid, if challenged, or that they will have sufficient scope or strength to protect us. 26 It is also possible that competitors or other unauthorized third parties may obtain, copy, use or disclose, illegally or otherwise, our proprietary technologies and processes, despite our efforts to protect our proprietary technologies and processes. 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. There are entities whom we believe may infringe our IP. Enforcement of our rights often requires litigation. If we bring a patent infringement action and are not successful, our competitors would be able to use similar technology to compete with us. Moreover, the defendant in such an action may successfully countersue us for infringement of their patents or assert a counterclaim that our patents are invalid or unenforceable. Also, the laws of some foreign countries may not protect our IP to the same extent as do U.S. laws. In addition to patent protection of IP rights, we consider elements of our product designs and processes to be proprietary and confidential. We rely upon employee, consultant and vendor non-disclosure agreements and contractual provisions and a system of internal safeguards to protect our proprietary information. However, any of our registered or unregistered IP rights may be challenged or exploited by others in the industry, which could harm our operating results. The success of our branded products depends in part on the positive image that consumers have of our brands. We believe the popularity of our brands makes them a target of counterfeiting or imitation, with third parties attempting to pass off counterfeit products as our products. Any occurrence of counterfeiting, imitation or confusion with our brands could adversely affect our reputation and impair the value of our brands, which in turn could negatively impact sales of our branded products, our share and our gross margin, as well as increase our administrative costs related to brand protection and counterfeit detection and prosecution. The costs of compliance with state, federal and international legal and regulatory requirements, such as environmental, labor, trade, health, safety, data privacy, anti-corruption and tax regulations, customers’ standards of corporate citizenship, and industry and coalition standards, such as those established by the Responsible Business Alliance (‘‘RBA’’), 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, data privacy, anti-corruption 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 suppliers and partners 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 suppliers or partners 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, or legal liability and reputational damage, which would have a materially adverse effect on our business, operating results and financial condition. In connection with our compliance with environmental laws and regulations, as well as our compliance with industry and coalition environmental initiatives, such as those established by the RBA, 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 and operating results to suffer. Violation of applicable laws, including labor or environmental laws, and certain other practices by our suppliers, customers or partners could harm our business. We expect our suppliers, customers and partners 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, customers, partners or their labor or environmental practices. The violation of labor, environmental or other laws by any of them, or divergence of their 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 exposing us to potential liability for our suppliers’, customers’ or partners’ wrongdoings. 27 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 are 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. Further, 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, which may prove to be inaccurate. 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, excess inventory, and price decreases, which could impact our sales, ASPs and gross margin, thereby adversely affecting our operating results and our financial condition. 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. In addition, some of our components have long lead-times, requiring us to place orders several months in advance of anticipated demand. Such long lead-times increase the risk of excess inventory or loss of sales in the event our forecasts vary substantially from actual demand. Our vertical integration of some of our products makes us dependent on our ability to timely and cost-effectively develop products with leading technology and overall quality, increasing capital expenditure costs and asset utilization risks for our business. We develop flash-based memory as well as other non-volatile memory technology through our partnership with TMC; we are also vertically integrated in a substantial portion of the recording heads and magnetic media used in the hard drive products we produce. Consequently, for some of our products, we are more dependent upon our own development and execution efforts and less able to take advantage of technologies developed by other manufacturers. Since we may not have access to alternative technologies that we do not develop internally, we may have to pay royalties in order to access those technologies. In addition, we may be unsuccessful in timely and cost-effectively developing and manufacturing products using future technologies. We also may not effectively transition our 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 products we manufacture. If we are unable to timely and cost-effectively develop products with leading technology and overall quality, continuing the cost reductions necessary to maintain adequate gross margin and our ability to sell our products may be significantly diminished, which could materially and adversely affect our business and financial results. Further, as a result of our vertical integration of some of our products, 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, some of our assets may face underutilization that may impact our operating results. We are therefore subject to additional risks related to overall asset utilization, including the need to operate at high levels of utilization to drive competitive costs and the need for assured supply of components that we do not manufacture ourselves. In addition, 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 these challenges, our ongoing operations could be disrupted, resulting in a decrease in our revenue or profit margins and negatively impacting our operating results. 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, and may continue to create, 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, our suppliers or our customers 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. Future 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, R&D activities (including our operations in 28 Israel) or shipments of our products, our business, operating results and financial condition could be adversely affected. Any of these events could also increase volatility in the U.S. and world financial markets, which could have a negative effect on our stock price and may limit the capital resources available to us and our customers or suppliers, or adversely affect consumer confidence. Sudden disruptions to the availability of air transportation, or ocean or land 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 air transportation, cargo operations or ocean, rail or truck 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 receive shipments from our suppliers or deliver our products. Our license and royalty revenue may fluctuate or decline significantly in the future due to license agreement expirations or renewals, declines in sales of the products or use of technology underlying the license and royalty revenue by our licensees, or if licensees fail to perform on a portion or all of their contractual obligations. If our existing licensees do not renew their licenses upon expiration, renew or sign new agreements on less favorable terms, exercise their option to terminate the license or fail to exercise their option to extend the licenses, or we are not successful in signing new licensees in the future, our license revenue, profitability and cash provided by operating activities would be harmed and we may incur significant patent litigation costs to enforce our patents against these licensees. As our older patents expire, and the coverage of our newer patents may be different, it may be more difficult to negotiate or renew favorable license agreement terms or a license agreement at all. Our agreements may require us in certain instances to recognize license revenue related to a particular licensee all in one period instead of over time, which could create additional volatility in our licensing revenue. A portion of our license and royalty revenue is based on sales of product categories as well as the underlying technology, and fluctuations in the sales of those products or technology adoption rates would also result in fluctuations in the license and royalty revenue due to us under our agreements. If our licensees or we fail to perform on contractual obligations, we may incur costs to enforce or defend the terms of our licenses and there can be no assurance that our enforcement, defense or collection efforts will be effective. If we license new IP from third parties or existing licensees, we may be required to pay license fees, royalty payments or offset existing license revenue. We may enter into agreements with customers, suppliers or partners that could limit our ability to monetize our IP or could result in us being required to provide IP indemnification to our customers, suppliers or partners. In addition, we may be subject to disputes, claims or other disagreements on the timing, amount or collection of royalties or license payments under our license agreements. Flash Ventures’ equipment lease agreements contain covenants and other cancellation events, and cancellation of the leases would harm our business, operating results and financial condition. Flash Ventures sells to and leases back from a consortium of financial institutions (‘‘lessors’’) a portion of its equipment and Flash Ventures has entered into equipment lease agreements, most of which we and TMC each guarantee half of the total outstanding obligations and some of which we guarantee in full for our share of the Flash Ventures investment. As of June 29, 2018, the portion of outstanding Flash Ventures’ lease obligations covered by our guarantees totaled approximately $1.22 billion, based upon the Japanese yen to U.S. dollar exchange rate at June 29, 2018. The equipment lease agreements contain covenants and cancellation events that are customary for Japanese lease facilities and that relate to Flash Ventures and each of the guarantors. Cancellation events relating to the guarantors include, among other things, an assignment of all or a substantial part of a guarantor’s business, a bankruptcy event involving a guarantor and acceleration of other monetary debts of a guarantor above a specified threshold. The breach of a covenant or the occurrence of another cancellation event could result in an acceleration of the Flash Ventures’ lease obligations. If a cancellation event were to occur, Flash Ventures would be required to negotiate a resolution with the lessors, as well as other parties to the lease transactions, to avoid cancellation and acceleration of the lease obligations. Such resolution could include, among other things, supplementary security to be supplied by us, as guarantor, increased interest rates or waiver fees. If a cancellation event occurs and we fail to reach a resolution, we may be required to pay all or a portion of the outstanding lease obligations covered by our guarantees, which would significantly reduce our cash position and may force us to seek additional financing, which may not be available on terms acceptable to us, if at all. 29 Any decisions to reduce or discontinue paying cash dividends to our shareholders or to reduce or discontinue repurchases of shares of our common stock pursuant to our previously announced stock repurchase program could cause the market price for our common stock to decline. We may modify, suspend or cancel our cash dividend policy in any manner and at any time. In addition, we may reduce or discontinue repurchases of shares of our common stock as we deem appropriate and as market conditions allow. Any reduction or discontinuance by us of the payment of quarterly cash dividends or the 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 cause the market price of our common stock to decline. 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, cost of goods sold, 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. In addition, our purchases of flash-based memory from Flash Ventures and our investment in Flash Ventures are denominated in Japanese yen. If the Japanese yen appreciates against the U.S. dollar, our cost of purchasing flash-based memory wafers and the cost to us of future capital funding of Flash Ventures would increase, which could negatively impact our operating results. If any of these events occur, they 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 U.S. Therefore, as a substantial portion of our sales are from countries outside the U.S., 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 U.S. We attempt 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. Thus, our decisions and hedging strategy with respect to currency risks may not be successful and harm our operating results. Further, the ability to enter into foreign exchange contracts with financial institutions is based upon our available credit from such institutions and compliance with covenants and other restrictions. Operating losses, third party downgrades of our credit rating or instability in the worldwide financial markets could impact our ability to effectively manage our foreign currency exchange rate risk. Hedging also exposes us to the credit risk of our counterparty financial institutions. 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. 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. 30 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: • weakness in demand for one or more product categories; • the timing of orders from and shipment of products to major customers, loss of major customers; • our product mix; • reductions in the ASPs of our products and lower margins; • excess output, capacity or inventory, resulting in lower ASPs, financial charges or impairments, or insufficient output, capacity or inventory, resulting in lost revenue opportunities; • inability to successfully transition to 3D NAND or other technology developments, or other failure to reduce product costs to keep pace with reduction in ASPs; • manufacturing delays or interruptions; • delays in design wins or customer qualifications, acceptance by customers of competing products in lieu of our products; • success of our partnerships and joint ventures, in particular the volume, timing and cost of wafer production at Flash Ventures, and our success in managing the relationships with our strategic partners; • inability to realize the potential benefits of our acquisitions and the success of our integration efforts; • ability to penetrate new markets for our storage solutions; • variations in the cost of and lead times for components for our products, disruptions of our supply chain; • limited availability of components that we obtain from a single or a limited number of suppliers; • seasonal and other fluctuations in demand often due to technological advances; • increase in costs due to warranty claims; • higher costs as a result of currency exchange rate fluctuations; 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; • accruals for product returns; 31 • accruals for litigation and other contingencies; • liabilities for unrecognized tax benefits; and • provisional estimates related to tax reform. In addition, changes in existing accounting or taxation rules or practices, new accounting pronouncements or taxation rules, or varying interpretations of current accounting pronouncements or taxation practice could have an adverse effect on our results of operations and financial condition. 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; • perceptions about our strategic relationships and joint ventures, access to supply of flash-based memory, new technologies and technology transitions; • 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; • 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, and any litigation; • 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, flash memory, computer, mobile, 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; • announcements relating to dividends and share repurchases; and • macroeconomic conditions that affect the market generally and, in particular, developments related to market conditions for our industry. In addition, the sale of substantial amounts of shares of our common stock, or the perception that these sales may occur, could adversely affect the market price of our common stock. Further, 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 may 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. 32 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 investment grade corporate securities, bank deposits, asset backed securities and U.S. government and agency securities. 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 Federal Deposit Insurance Corporation (FDIC) limits could also have an adverse impact on our financial position. In addition, if we are unable to generate sufficient cash flows from operations to repay our indebtedness, fund acquisitions, pay dividends, or repurchase shares of our common stock, we may choose or be required to increase our borrowings, if available, or to repatriate funds to the U.S. at an additional tax cost. We must comply with regulations regarding the conversion and distribution of funds earned in the local currencies of various countries. If we cannot comply with these or other applicable regulations, we may face increased difficulties in using cash generated in these countries. Item 1B.

(2) Our Board of Directors previously authorized $5.00 billion for the repurchase of our common stock. In 2018, we repurchased 7.1 million shares for a total cost of $591 million. Subsequent to June 29, 2018 and through July 25, 2018, we repurchased an additional 0.8 million shares for a total cost of $61 million. On July 25, 2018, our Board of Directors authorized a new $5.00 billion share repurchase program that is effective through July 25, 2023, replacing all prior programs. 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. We expect stock repurchases to be funded principally by operating cash flows. Subsequent to July 25, 2018 and through August 22, 2018, we repurchased an additional 5.9 million shares for a total cost of $404 million under this new program. 36 Dividends to Shareholders 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 2018, we declared aggregate cash dividends of $2.00 per share of our common stock, totaling $592 million. The following table provides information about the quarterly dividends our Board of Directors declared in the last two fiscal years: Record Date September 30, 2016 December 30, 2016 March 31, 2017 June 30, 2017 September 29, 2017 December 29, 2017 March 30, 2018 June 29, 2018 Payment Date October 17, 2016 January 17, 2017 April 17, 2017 July 17, 2017 October 16, 2017 January 16, 2018 April 16, 2018 July 16, 2018 Dividend Per Share $0.50 $0.50 $0.50 $0.50 $0.50 $0.50 $0.50 $0.50 In addition, on August 1, 2018, we declared a cash dividend of $0.50 per share of our common stock to our shareholders of record as of September 28, 2018, which will be paid on October 15, 2018. The amount of future dividends under our cash dividend policy, and the declaration and payment thereof, will be based upon all relevant factors, including our financial position, results of operations, cash flows, capital requirements and restrictions under our financing agreements, and shall be in compliance with applicable law. Our Board of Directors retains the power to modify, suspend or cancel the cash dividend policy in any manner and at any time as it may deem necessary or appropriate in the future. 37 Stock Performance Graph The following graph compares the cumulative total stockholder return of our common stock with the cumulative total return of the S&P 500 Index and the Dow Jones U.S. Technology Hardware & Equipment Index for the five years ended June 29, 2018.

Item 7. Management’s Discussion and Analysis of Financial Conditions and Results of Operations Our Company We are a leading developer, manufacturer and provider of data storage devices and solutions that address the evolving needs of the information technology (‘‘IT’’) industry and the infrastructure that enables the proliferation of data in virtually every other industry. Our broad portfolio of technology and products address the following key markets: Client Devices; Data Center Devices and Solutions; and Client Solutions. We also generate license and royalty revenue related to our intellectual property (‘‘IP’’), which is included in each of these three categories. Key Developments Debt Facilities During the year ended June 29, 2018, we entered into new debt facilities, amended our existing credit agreement, increased our revolving credit facility, and repaid higher rate debt. These actions, along with scheduled principal payments, reduced the aggregate principal amount of our debt by $1.98 billion since the beginning of the fiscal year and reduced our overall interest cost, extended the tenor of our debt and provided additional flexible capacity to meet our financing needs. The financing arrangement activities were as follows in the year ended June 29, 2018: • In November 2017, we settled our then-existing U.S. dollar-denominated term B-2 loans (‘‘U.S. Term Loan B-2’’) with the proceeds of a new issuance of a $2.96 billion U.S. dollar-denominated term loan (‘‘U.S. Term Loan B-3’’) at an interest rate lower than our U.S. Term Loan B-2 tranche. In February 2018, we made a voluntary partial 39 prepayment of $500 million of the U.S. Term Loan B-3 using drawings from the Revolving Facility (as defined below), and in May 2018, we settled our then-existing U.S. dollar-denominated term B-3 loans with the proceeds of a new issuance of a $2.46 billion U.S. dollar-denominated term loan (‘‘U.S. Term Loan B-4’’) at an interest rate lower than our U.S. Term Loan B-3 tranche. • In November 2017, we made a voluntary prepayment of the full principal amounts of our Euro-denominated term B-2 loans (‘‘Euro Term Loan B-2’’) using cash on hand. • In February 2018, we issued $2.3 billion aggregate principal amount of 4.750% senior unsecured notes due 2026 (the ‘‘2026 Senior Unsecured Notes’’). • In February 2018, we issued a $1.1 billion aggregate principal amount of 1.50% convertible senior notes due 2024 (the ‘‘2024 Convertible Notes’’). • In February 2018, we entered into an amendment to the credit agreement entered into on April 29, 2016 to provide for, among other things, (i) the issuance of a new $5.02 billion of term loan A-1 due 2023 (the ‘‘Term Loan A-1’’), (ii) a new $2.25 billion revolving credit facility maturing in 2023 (the ‘‘Revolving Facility’’), which replaced our prior $1.50 billion revolving credit facility maturing in 2021, (iii) modifications to the restrictive and financial maintenance covenants, to provide more flexibility and increased incremental debt capacity, (iv) amendments of the applicable varying interest rate margins to be based on our corporate credit ratings, and (v) upon the occurrence of certain circumstances, a release of the security and guarantees as well as further covenant flexibility and increased incremental debt capacity. We used a portion of the proceeds of the Term Loan A-1 to repay in full our previous variable interest rate Term Loan A maturing 2021 in the principal amount of $4.02 billion. • In February and March 2018, we completed the redemption of all of our outstanding 7.375% senior secured notes due 2023 in the aggregate principal amount of $1.875 billion (the ‘‘2023 Notes’’) and the tender offer and redemption and settlement of all of our outstanding 10.500% senior unsecured notes due 2024 in the aggregate principal amount of $3.350 billion (the ‘‘2024 Notes’’ and collectively with the 2023 Notes, the ‘‘Redeemed Notes’’). • In connection with the settlements of the various debt instruments described above during 2018, we incurred aggregate losses on extinguishment of debt of $899 million for the year ended June 29, 2018, consisting of $720 million of ‘‘make-whole’’ premiums and $179 million of unamortized issuance costs. For additional information regarding our debt facilities, see Part II, Item 8, Note 6, Debt, of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. Tax Reform On December 22, 2017, the President of the United States of America signed the Tax Cuts and Jobs Act (the ‘‘2017 Act’’), which includes a broad range of tax reform proposals affecting businesses, including a reduction in the U.S. federal corporate tax rate from 35% to 21% and a one-time mandatory deemed repatriation tax on earnings of certain foreign subsidiaries that were previously tax deferred, and creates new taxes on certain foreign earnings. As a result of the 2017 Act, we have made a reasonable estimate of the effects on our existing deferred tax balances and the one-time mandatory deemed repatriation tax required by the 2017 Act and have recognized a provisional income tax expense of $1.57 billion for the one-time mandatory deemed repatriation tax and a provisional income tax benefit of $65 million related to the re- measurement of deferred tax assets and liabilities for the year ended June 29, 2018. For additional information regarding the 2017 Act, see Part II, Item 8, Note 13, Income Tax Expense (Benefit), of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. See also the discussion in ‘‘Results of Operations - Income Tax Expense’’ and ‘‘Liquidity and Capital Resources’’ below for information regarding the impact of the 2017 Act on our financial condition, results of operations and cash flows. Closure of Foreign Manufacturing Facility In July 2018, we announced the closing of our manufacturing facility in Kuala Lumpur, Malaysia, in order to reduce manufacturing costs and consolidate hard disk drive (‘‘HDD’’) operations into Thailand. We expect the closure to be substantially completed by the end of the calendar year 2019 and to result in total pre-tax charges of approximately $160 million. These charges are expected to consist of approximately $85 million in employee termination benefits and 40 $75 million in asset-related, contract termination and other charges. During the year ended June 29, 2018, we recognized $56 million in employee termination benefits within Employee termination, asset impairment and other charges in the Consolidated Statements of Operations. For additional information, see Part II, Item 8, Note 15, Employee Termination, Asset Impairment and Other Charges, of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K.

Net revenue increased $1.55 billion, or 8%, in 2018 compared to 2017, driven by increases in all end markets. Client Devices revenue for the year ended June 29, 2018 increased 6% year over year, primarily driven by growth in embedded flash products offset by client compute HDD devices. Our revenue for Data Center Devices and Solutions for the year ended June 29, 2018 increased 10% year over year, driven primarily by a significant increase in sales from our capacity enterprise HDD, partially offset by our expected lower sales of performance enterprise HDDs. Client Solutions revenue for the year ended June 29, 2018 increased 10% year over year, reflecting growth in both retail flash and HDD products. Changes in the net revenue by geography 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 2018, 2017 and 2016, these programs represented 12%, 12% and 13% of gross revenues, respectively. The amounts attributed to our sales incentive and marketing programs generally vary according to several factors including industry conditions, list pricing strategies, seasonal demand, competitor actions, channel mix and overall availability of products. Changes in future customer demand and market conditions may require us to adjust our incentive programs as a percentage of gross revenue. Gross Profit and Gross Margin. Gross profit increased $1.63 billion, or 27%, in 2018 compared to 2017, primarily due to the increase in revenue and improvement in our gross margin. The improvement in our gross margin for the year ended June 29, 2018 was primarily due to a favorable demand environment for flash-based products, a higher mix of revenue from sales of flash-based products and capacity enterprise devices; and improvements in our production costs from technology transitions. In addition, gross profit was impacted by amortization expense on acquired intangible assets, stock-based compensation, charges related to the implementation of cost-saving initiatives and other charges, which aggregated $1.06 billion, or 5.2%, of revenue, in 2018, compared to $1.14 billion, or 6.0%, of revenue, in 2017. The flash industry is characterized by cyclicality as it responds to variations in customers’ demand for products and expands or manages production capacity to meet that demand. The favorable demand environment for flash-based products experienced by the industry for the last several quarters is beginning to normalize as technology conversions are maturing and manufacturing yields are improving, thus increasing flash supply. As a result, we expect our gross margins to decline in fiscal 2019 compared to fiscal 2018 due to expected declines in the average selling price per gigabyte of flash memory as supply grows to meet demand. 42 Fiscal Year 2017 Net Revenue and Gross Margin Compared to Fiscal Year 2016 Net Revenue and Gross Margin Net Revenue. Net revenue increased $6.10 billion, or 47%, as compared to 2016, primarily due to a full year of revenue from the sale of flash-based products following the acquisition of SanDisk Corporation (‘‘SanDisk’’) in May 2016 (the ‘‘Merger’’), compared to a partial year of such revenue in the prior year. This increase was partially offset by lower revenue related to lower PC and enterprise HDD shipments. Changes in the mix of net revenue by end market for 2017, as compared to 2016, reflect the full year increase in revenues from the Merger which has resulted in comparatively higher revenue in Client Devices and Client Solutions than our pre-acquisition business. Changes in the mix of net revenue by geography for 2017, as compared to 2016, reflect the additional revenues from the Merger which has resulted in comparatively higher revenue in Asia than our pre-acquisition business. Gross Profit and Gross Margin. Gross profit increased $2.64 billion, or 77%, in 2017, as compared to 2016, primarily due to the increase in revenue mentioned above. In addition, gross profit for 2017 was impacted by amortization expense on acquired intangible assets, charges related to the implementation of cost-saving initiatives, stock-based compensation and acquisition related charges, which aggregated $1.14 billion, or 6.0% of revenue, for 2017, and $375 million, or 2.9% of revenue, for 2016. Gross margin increased to 31.8% for 2017, as compared to 26.4% for 2016. The increase in gross margin was primarily due to sales of flash-based products following the Merger, as such products have comparatively higher gross margins than our pre-acquisition products, cost improvements across all products driven by manufacturing integration activities and cost improvements as flash-based technology transitions to more cost efficient designs. Operating Expenses Fiscal Year 2018 Operating Expenses Compared to Fiscal Year 2017 Operating Expenses Research and development (‘‘R&D’’) expense decreased $41 million, or 2%, in 2018 compared to 2017, primarily due to our cost saving initiatives and lower variable compensation expense, partially offset by further investments in flash technologies. In addition, fiscal year 2018 included aggregate charges of $179 million related to stock-based compensation expenses, charges related to the implementation of cost-saving initiatives, acquisition-related charges and other charges compared to $199 million in 2017. Selling, general and administrative (‘‘SG&A’’) expense increased $28 million, or 2%, in 2018 compared to 2017, primarily due to operating expenses from recent acquisitions and higher consulting services, partially offset by lower variable compensation expense and lower charges related to stock-based compensation expenses, amortization expense on acquired intangible assets, charges related to the implementation of cost-saving initiatives, acquisition-related charges and other charges aggregating to $340 million in 2018 compared to $404 million in 2017. Employee termination, asset impairment and other charges was $215 million in 2018, a decrease of $17 million, or 7%, from 2017. The decrease is related to our progress toward completion of our integration restructuring plan, partially offset by the announced closure of our foreign manufacturing facility. For additional information regarding employee termination, asset impairment and other charges, see Part II, Item 8, Note 15, Employee Termination, Asset Impairment and Other Charges, of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. Fiscal Year 2017 Operating Expenses Compared to Fiscal Year 2016 Operating Expenses R&D expense increased $814 million, or 50%, in 2017 compared to 2016, primarily due to the Merger and continued development of flash-based technology. Fiscal year 2017 also included aggregate charges of $199 million related to stock-based compensation expenses, charges related to the implementation of cost-saving initiatives, acquisition-related charges and other discrete charges, compared to $106 million in 2016 related to such charges. SG&A expense increased $448 million, or 45%, in 2017 compared to 2016, primarily due to the Merger. Fiscal year 2017 also included aggregate charges of $404 million related to stock-based compensation expenses, amortization expense on acquired intangible assets, charges related to the implementation of cost-saving initiatives, acquisition-related charges and other discrete charges, compared to $379 million in 2016 related to such charges. Employee termination, asset impairment and other charges was $232 million in 2017, a decrease of $113 million, or 33%, from 2016. These charges in 2017 primarily related to further actions under the Restructuring Plan 2016 associated 43 with the integration and business realignment of substantial portions of our business. For additional information regarding employee termination, asset impairment and other charges, see Part II, Item 8, Note 15, Employee Termination, Asset Impairment and Other Charges, of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. Interest and Other Income (Expense) Fiscal Year 2018 Interest and Other Expense, Net Compared to Fiscal Year 2017 Interest and Other Expense, Net Total interest and other expense, net increased $347 million in 2018, primarily due to losses on extinguishment of debt of $899 million in 2018 compared to $274 million in 2017. These losses were partially offset by lower interest expense resulting from reductions in the principal amount of debt and lower interest rates, lower impairment charges related to our cost-method investments, and higher interest income due to increased rates of return on investment (for additional information, see Part II, Item 8, Note 6, Debt, of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K) and impairment charges related to our cost-method investments. Fiscal Year 2017 Interest and Other Expense, Net Compared to Fiscal Year 2016 Interest and Other Expense, Net Total interest and other expense, net increased $872 million in 2017, primarily due to a full year of interest expense in 2017 resulting from the additional debt issued in connection with the Merger compared to only a partial year of such expense in 2016, as well as losses on the settlements of certain of our term loans and impairment charges related to our cost-method investments. Income Tax Expense (Benefit) The following table sets forth income tax information from our Consolidated Statement of Operations by dollar and effective tax rate: 2018 2017 2016 (in millions, except percentages) Income before taxes. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

For fiscal year 2019 and beyond, we will utilize the enacted U.S. federal corporate tax rate of 21%. Consistent with applicable Securities and Exchange Commission (‘‘SEC’’) guidance, we made a reasonable estimate of the effects on our existing deferred tax balances and the one-time mandatory deemed repatriation tax required by the 2017 Act and have recognized a provisional income tax expense of $1.57 billion for the one-time mandatory deemed repatriation tax and a provisional income tax benefit of $65 million related to the re-measurement of deferred tax assets and liabilities for the year ended June 29, 2018. For other elements of tax expense noted in Part II, Item 8, Note 13, Income Tax Expense (Benefit), of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K, or where we have not made an election, we have not been able to make a reasonable estimate and continue to account for such items based on the provisions of the tax laws that were in effect immediately prior to the 2017 Act. As we finalize the accounting for the tax effects of the enactment of the 2017 Act during a one-year measurement period permitted by applicable SEC guidance, we expect to reflect adjustments to the recorded provisional amounts and record additional tax effects of the 2017 Act. The primary drivers for the difference between the effective tax rate for the year ended June 29, 2018 and the blended U.S. Federal statutory rate of 28% are provisional taxes recognized as a result of the 2017 Act and an increase to the valuation allowance for net operating loss carryforwards from restructuring activities, which are partially offset by the 2018 generation of tax credits and tax holidays in Malaysia, Philippines, Singapore and Thailand that expired or will expire at various dates during fiscal years 2018 through 2030. 44 The primary drivers for the difference between the effective tax rate for the year ended June 30, 2017 and the U.S. Federal statutory rate of 35% are taxes related to the integration of SanDisk and an increase in the valuation allowance for both acquired tax attributes and net operating loss carryforwards from restructuring activities, which are partially offset by the 2017 generation of tax credits and foreign income taxed at lower rates due primarily to tax holidays in Malaysia, Philippines, Singapore and Thailand. The primary drivers for the difference between the effective tax rate for the year ended July 1, 2016 and the U.S. Federal statutory rate of 35% are the 2016 generation of tax credits and foreign income taxed at lower rates due primarily to tax holidays in Malaysia, Philippines, Singapore and Thailand. The 2017 Act is expected to have an unfavorable impact on our effective tax rate for fiscal year 2018 due to the mandatory deemed repatriation tax offset in part by the re-measurement of deferred taxes and the reduction in the corporate tax rate. In future years, certain additional provisions of the 2017 Act, such as a minimum tax on foreign earnings, will also apply to us and, as a result, we generally expect our effective tax rate to increase from the rate expected for fiscal year 2018 (excluding the mandatory deemed repatriation tax and the re-measurement of deferred taxes). Our estimate of the effective tax rate increase is subject to our assertion as to whether foreign undistributed earnings are indefinitely reinvested and to other calculations and elections during the measurement period. Our total tax expense in future fiscal years will also vary as a result of discrete items such as excess tax benefits or deficiencies. For additional information regarding income tax expense (benefit), see Part II, Item 8, Note 13, Income Tax Expense (Benefit), of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K.

Our ability to sustain our working capital position is subject to a number of risks that we discuss in Part I, Item 1A, Risk Factors, in this Annual Report on Form 10-K. During 2019, we expect cash used for purchases of property, plant and equipment and net activity in notes receivable and equity investments relating to our Flash Ventures joint venture with Toshiba Memory Corporation to be approximately $1.50 billion to $1.90 billion. The total expected cash to be used could vary depending on the timing and completion of various capital projects and the availability, timing and terms of related financing. Pursuant to the 2017 Act, we are required to pay a one-time deemed repatriation tax related to the undistributed earnings of our foreign subsidiaries. For 2018, we recorded a provisional amount for the mandatory deemed repatriation tax liability of $1.57 billion, which is payable over an 8-year period as further discussed below under ‘‘Short and Long-term Liquidity-Contractual Obligations and Commitments.’’ The provisional amount included in the Consolidated Financial Statements may change when we finalize the calculation of our post-1986 foreign earnings and profits that were previously deferred from U.S. income taxes and the amount of foreign earnings held in cash or other specified assets. For additional information regarding our total tax liability for the mandatory repatriation tax, see Part II, Item 8, Note 13, Income Tax Expense (Benefit), of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. A total of $4.15 billion and $4.99 billion of our cash and cash equivalents was held outside of the U.S. as of June 29, 2018 and June 30, 2017, respectively. Although the mandatory deemed repatriation tax has removed U.S. federal taxes on 45 distributions to the U.S., we continue to evaluate the expected manner of recovery to determine whether or not to continue to assert indefinite reinvestment on a part or all the foreign undistributed earnings. This requires us to re-evaluate the existing short and long-term capital allocation policies in light of the 2017 Act and calculate the tax cost that is incremental to the U.S. deemed repatriation tax (e.g., foreign withholding, state income taxes, and additional U.S. tax on currency transaction gains or losses) of repatriating cash to the U.S. While the current tax expense is based upon an assumption that foreign undistributed earnings are indefinitely reinvested, our plan may change upon the completion of long-term capital allocation plans in light of the 2017 Act and completion of the calculation of the incremental tax effects on the repatriation of foreign undistributed earnings. In the event we determine not to continue to assert the permanent reinvestment of part or all of our foreign undistributed earnings, such a determination could result in the accrual and payment of additional federal, foreign, state and local taxes. Operating Activities Cash flow from operating activities primarily consists of net income, adjusted for non-cash charges, plus or minus changes in other operating assets and liabilities. This represents our principal source of cash. Net cash provided by changes in other operating assets and liabilities was $486 million for 2018, as compared to net cash provided by changes in other operating assets and liabilities of $91 million for 2017. The increase in cash provided by changes in other operating assets and liabilities in 2018 primarily reflects the payable recorded for the mandatory repatriation tax as described in the Tax Reform section of Key Developments above. Changes in our other operating assets and liabilities are also largely affected by our working capital requirements, which are dependent on the effective management of our cash conversion cycle. Our cash conversion cycle measures how quickly we can convert our products into cash through sales. The cash conversion cycles were as follows: 2018 2017 2016 Days sales outstanding . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Changes in days in inventory (‘‘DIOs’’) are generally related to the timing of inventory builds. Changes in days payables outstanding (‘‘DPOs’’) are generally related to production volume and the timing of purchases during the period. From time to time, we modify the timing of payments to our vendors. We make modifications primarily to manage our vendor relationships and to manage our cash flows, including our cash balances. Generally, we make the payment term modifications through negotiations with our vendors or by granting to, or receiving from, our vendors’ payment term accommodations. For 2018, DSO increased by 2 days over the prior year, primarily reflecting the timing of shipments and customer receipts. DIO increased by 18 days over the prior year, primarily reflecting increases in flash inventory and an increase in HDD inventory due to ongoing hard drive manufacturing transformation activities. The decrease in DPO primarily reflects the increased production volume and timing of vendor payments. The working capital metrics in 2016 were notably impacted by the inclusion of SanDisk’s accounts receivable, inventory and accounts payable balances as of July 1, 2016, but only including SanDisk’s revenue and cost of sales following the Merger. The Merger inflated DSO, DIO and DPO by 12 days, 32 days, and 14 days, respectively. Excluding the impact of the Merger in 2016, DSO in 2017 increased by 8 days over 2016, primarily reflecting timing of customer receipts in the prior year. Excluding the impact of the Merger in 2016, DIO in 2017 increased by 16 days over 2016. The increase in DIO primarily reflects short-term build-up of inventory to maintain supply as we close certain facilities and transition production. Excluding the impact of the Merger in 2016, DPO in 2017 increased by 2 days over 2016, primarily reflecting routine variations in timing of purchases and payments during the period. 46 Investing Activities During 2018, net cash used in investing activities primarily consisted of $835 million of capital expenditures, a net $742 million increase in notes receivable issuances to Flash Ventures to fund its capital expansion, and $100 million for acquisitions. Net cash used in investing activities for 2017 primarily consisted of $578 million of capital expenditures and a $277 million net increase in notes receivable issuances to and investments in Flash Ventures, partially offset by a net reduction of our available for sale securities of $230 million. During 2016, net cash used in investing activities primarily consisted of $9.84 billion related to the Merger, net of cash acquired, $584 million of capital expenditures, $90 million net increase in notes receivable to Flash Ventures and a net $76 million of other investing activities, partially offset by $977 million of proceeds from a net decrease in investments and sales of marketable securities. Our cash equivalents are primarily invested in money market funds that invest in U.S. Treasury securities and U.S. Government agency securities as well as bank certificates of deposit. In addition, we invest directly in U.S. Treasury securities, U.S. and International Government agency securities, certificates of deposit, asset-backed securities and corporate and municipal notes and bonds. Financing Activities During 2018, net cash used in financing activities primarily consisted of $17.07 billion in debt repayments, $593 million to pay dividends on our common stock and $591 million of share repurchases, partially offset by net proceeds of $14.28 billion from debt issuances and draws under our Revolving Facility. During 2017, net cash used in financing activities primarily consisted of $11.70 billion to repay debt, $574 million to pay dividends on our common stock and $492 million to settle convertible debt, partially offset by $7.90 billion of proceeds from debt, net of issuance costs, a net $230 million provided by employee stock plans and $61 million of proceeds from call options. During 2016, net cash provided by financing activities consisted of $16.58 billion of proceeds from debt, net of issuance costs, $409 million of proceeds from call options and a net $74 million provided by employee stock plans, offset by a net $2.61 billion to settle convertible debt, $2.57 billion to repay debt and our prior revolving credit facility, $613 million for payment upon settlement of warrants, $464 million to pay dividends on our common stock and $60 million to repurchase shares of our common stock. Off-Balance Sheet Arrangements Other than the commitments related to Flash Ventures, 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 other material off-balance sheet financing arrangements or liabilities, guarantee contracts, retained or contingent interests in transferred assets, or any other 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. For additional information regarding our off-balance sheet arrangements, see Part II, Item 8, Note 9, Commitments, Contingencies and Related Parties, of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. 47 Short and Long-term Liquidity Contractual Obligations and Commitments The following is a summary of our known contractual cash obligations and commercial commitments as of June 29, 2018: Total 1 Year (2019) Long-term debt, including current portion(1) . . . . . .

(2) Includes reimbursement for depreciation and lease payments on owned and committed equipment, funding commitments for loans and equity investments and reimbursement for other committed expenses, including R&D. Funding commitments assume no additional operating lease guarantees. Additional operating lease guarantees can reduce funding commitments. Debt See Part II, Item 8, Note 6, Debt, of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K for information regarding our indebtedness, including information about new borrowings and repayments, increased availability under our Revolving Facility and the principal repayment terms, interest rates, covenants and other key terms of our outstanding indebtedness. Flash Ventures Flash Ventures sells to and leases back from a consortium of financial institutions a portion of its tools and has entered into equipment lease agreements of which we guarantee half or all of the outstanding obligations under each lease agreement. The lease agreements contain customary covenants for Japanese lease facilities. In addition to containing customary events of default related to Flash Ventures that could result in an acceleration of Flash Ventures’ obligations, the lease agreements contain acceleration clauses for certain events of default related to the guarantors, including us. As of June 29, 2018, we were in compliance with all covenants under these Japanese lease facilities. See Part II, Item 8, Note 9, Commitments, Contingencies and Related Parties, of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K for information regarding Flash Ventures. Purchase Obligations 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. In addition, 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 48 above. We have also entered into long-term purchase agreements with various component suppliers that carry fixed volumes and pricing which obligate us to make certain future purchases, contingent on certain conditions of performance, quality and technology of the vendor’s components. These arrangements are included under ‘‘Purchase obligations’’ in the table above.

The payments are due with 8% of the tax to be paid in each of the first five years, 15% in the 6th year, 20% in the 7th year, and 25% in the 8th year. For additional information regarding our provisional estimate of the total tax liability for the mandatory repatriation tax, see Part II, Item 8, Note 13, Income Tax Expense (Benefit), of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. Unrecognized Tax Benefits As of June 29, 2018, the liability for unrecognized tax benefits (excluding accrued interest and penalties) was approximately $551 million. Accrued interest and penalties related to unrecognized tax benefits as of June 29, 2018 was approximately $110 million. Of these amounts, approximately $508 million could result in potential cash payments. We are not able to provide a reasonable estimate of the timing of future tax payments related to these obligations. For additional information regarding our total tax liability for unrecognized tax benefits, see Part II, Item 8, Note 13, Income Tax Expense (Benefit), of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. Interest Rate Swap We have entered into interest rate swap agreements to moderate our exposure to fluctuations in interest rates underlying our variable rate debt. For a description of our current interest rate swaps, see Part II, Item 7A, Quantitative and Qualitative Disclosures About Market Risk and Part II, Item 8, Note 5, Derivative Instruments and Hedging Activities, of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. Foreign Exchange Contracts We purchase 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. For a description of our current foreign exchange contract commitments, see Part II, Item 7A, Quantitative and Qualitative Disclosures About Market Risk and Part II, Item 8, Note 5, Derivative Instruments and Hedging Activities, of 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, environmental compliance or from IP infringement claims made by third parties. In addition, we have entered into indemnification agreements with our directors and certain of 49 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. Stock Repurchase Program Our Board of Directors previously authorized $5.00 billion for the repurchase of our common stock. In 2018, we repurchased 7.1 million shares for a total cost of $591 million. Subsequent to June 29, 2018 and through July 25, 2018, we repurchased an additional 0.8 million shares for a total cost of $61 million. On July 25, 2018, our Board of Directors authorized a new $5.00 billion share repurchase program that is effective through July 25, 2023, replacing all prior programs. 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. We expect stock repurchases to be funded principally by operating cash flows. Subsequent to July 25, 2018 and through August 22, 2018, we repurchased an additional 5.9 million shares for a total cost of $404 million under this new program. Cash Dividend Since the first quarter of 2013, we have issued a quarterly cash dividend. During the year ended June 29, 2018, we declared aggregate cash dividends of $2.00 per share of our common stock totaling $592 million. On May 2, 2018, we declared a cash dividend of $0.50 per share of our common stock to our shareholders of record as of June 29, 2018, which aggregated $148 million and was paid on July 16, 2018. On August 1, 2018, we declared a cash dividend of $0.50 per share of our common stock to our shareholders of record as of September 28, 2018, which will be paid on October 15, 2018. We may modify, suspend, or cancel our cash dividend policy in any manner and at any time. 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, see Part II, Item 8, Note 2, Recent Accounting Pronouncements, of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. Critical Accounting Policies and Estimates We have prepared the accompanying Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States (‘‘U.S. GAAP’’). The preparation of the financial statements requires the use of judgments and estimates that affect the reported amounts of revenues, expenses, assets, liabilities and shareholders’ equity. We have adopted accounting policies and practices that are generally accepted in the industry in which we operate. We believe the following are our most critical accounting policies that affect significant areas and involve judgment and estimates made by us. If these estimates differ significantly from actual results, the impact to Consolidated Financial Statements may be material. Revenue 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/or a right of return 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 and/or returns 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, historical and anticipated returns information and customer claim processing. If customer demand for our products or market conditions differ 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 50 of revenue. These amounts generally vary according to several factors including industry conditions, seasonal demand, competitor actions, channel mix and overall availability of product. 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. Total sales incentive and marketing programs have ranged from 12% to 13% of gross revenue and adjustments to revenue due to changes in accruals for these programs related to revenue reported in prior periods have generally averaged less than 1% of gross revenue over the last three fiscal years. 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. Inventories We value inventories at the lower of cost (first-in, first-out) or net realizable value. 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. For additional information, see Part II, Item 8, Note 16, Legal Proceedings, of 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. 51 Goodwill and Other Long-Lived Assets Goodwill is not amortized. Instead, it is tested for impairment on an annual basis or more frequently whenever events or changes in circumstances indicate that goodwill may be impaired. We perform our annual impairment test as of the first day of our fiscal fourth quarter. We use qualitative factors to determine whether goodwill is more likely than not impaired and whether a quantitative test for impairment is considered necessary. If we conclude from the qualitative assessment that goodwill is more likely than not impaired, we are required to perform a quantitative approach to determine the amount of 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. If our stock price decreases significantly, goodwill could become impaired, which could result in a material charge and adversely affect our results of operations. In-process research and development (‘‘IPR&D’’) is an intangible asset accounted as an indefinite-lived asset until the completion or abandonment of the associated R&D effort. During the development period, we conduct an IPR&D impairment test annually and whenever events or changes in facts and circumstances indicate that it is more likely than not that the IPR&D is impaired. Events which might indicate impairment include, but are not limited to, adverse cost factors, strategic decisions made in response to economic, market, and competitive conditions, the impact of the economic environment on us and our customer base. 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. Other long-lived intangible assets are amortized over their estimated useful lives based on the pattern in which the economic benefits are expected to be received. 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. 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, liabilities and commitments for product costs and operating expenses 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 speculative or trading purposes. For additional information, see Part II, Item 8, Note 4, Fair Value Measurements and Investments and Note 5, Derivative Instruments and Hedging Activities, of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. As of June 29, 2018, we had outstanding the foreign exchange contracts presented in the following table. The designated foreign exchange contracts are entered to protect the U.S. dollar value of our product cost and operating expenses. Changes in fair values of the non-designated foreign exchange contracts are recognized in other income (expense), net and are largely offset by corresponding changes in the fair values of the foreign currency denominated monetary assets and liabilities.

During 2018, 2017 and 2016, total net realized and unrealized transaction and foreign exchange contract currency gains and losses were not material to our Consolidated Financial Statements. Notwithstanding our efforts to mitigate some foreign exchange risks, we do not hedge all of our foreign currency exposures, and there can be no assurance that our mitigating activities related to the exposures that we hedge will adequately protect us against risks associated with foreign currency fluctuations. Disclosure About Other Market Risks Variable Interest Rate Risk Borrowings under our Revolving Facility and Term Loan A-1 bear interest at a rate per annum, at our option, of either an adjusted London Interbank Offered Rate (‘‘LIBOR’’) (subject to a 0.0% floor) plus an applicable margin varying from 1.125% to 2.000% or a base rate plus an applicable margin varying from 0.125% to 1.000%, in each case depending on our corporate credit ratings. As of June 29, 2018, the applicable margin based on our current credit ratings was 1.5%. Borrowings under our U.S. Term Loan B-4 bear interest at a rate per annum, at our option, of either an adjusted LIBOR (subject to a 0.0% floor) plus a margin of 1.75% or a base rate plus a margin of 0.75%. We have generally held a balance of fixed and variable rate debt. At June 29, 2018, 70% of the par value of our debt was at variable rates. We entered into pay-fixed interest rate swaps, which effectively converts $1.00 billion of our term loans to fixed rates through May 2020 and an incremental $1.00 billion through April 2023. As of June 29, 2018, we had $7.94 billion of variable rate debt. After giving effect to the $2.00 billion of interest rate swaps, we effectively had $5.94 billion of long-term debt subject to variations in interest rates and a one percent increase in the variable rate of interest would increase annual interest expense by $59 million.

We also have audited the Company’s internal control over financial reporting as of June 29, 2018, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of June 29, 2018 and June 30, 2017, and the results of its operations and its cash flows for each of the years in the three-year period ended June 29, 2018, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of June 29, 2018, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Basis for Opinions The Company’s management is responsible for these consolidated financial statements, 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 Item 9A, Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting 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 audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. Definition and Limitations of Internal Control Over Financial Reporting 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 generally accepted accounting principles, and that receipts and 55 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. /s/ KPMG LLP We have served as the Company’s auditor since 1970.

Organization and Basis of Presentation Western Digital Corporation (‘‘Western Digital’’ or ‘‘the Company’’) is a leading developer, manufacturer and provider of data storage devices and solutions that address the evolving needs of the information technology (‘‘IT’’) industry and the infrastructure that enables the proliferation of data in virtually every other industry. The Company’s broad portfolio of technology and products address the following key markets: Client Devices; Data Center Devices and Solutions; and Client Solutions. The Company also generates license and royalty revenue related to its intellectual property (‘‘IP’’) which is included in each of the three categories. Basis of Presentation 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’s fiscal year ends on the Friday nearest to June 30 and typically consists of 52 weeks. Approximately every six years, the Company reports a 53-week fiscal year to align the fiscal year with the foregoing policy. Fiscal years 2018, which ended on June 29, 2018; 2017, which ended on June 30, 2017; and 2016, which ended on July 1, 2016, were each comprised of 52 weeks, with all quarters presented consisting of 13 weeks. Basis of Consolidation The Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The functional currency of most of the Company’s foreign subsidiaries is the U.S. dollar. The accounts of these foreign subsidiaries have been remeasured using the U.S. dollar as the functional currency. Gains or losses resulting from remeasurement of these accounts from local currencies into U.S. dollars were immaterial to the Consolidated Financial Statements. Financial statements of the Company’s foreign subsidiaries for which the functional currency is the local currency are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities and a weighted average exchange rate for each period for statement of operations items. Translation adjustments are recorded in accumulated other comprehensive income, a component of shareholders’ equity. Reclassifications Certain prior year amounts have been reclassified in the consolidated balance sheets to conform to the current year presentation. Use of Estimates 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. 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 bank certificates of deposit with original maturities at purchase of three months or less. Cash equivalents are carried at cost plus accrued interest, which approximates fair value. 63 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Available-for-Sale Securities The Company invests in U.S. Treasury securities, U.S. and International Government agency securities, certificates of deposit, asset-backed securities, and corporate and municipal notes and bonds, with original maturities at purchase of more than three months. These investments are classified as available-for-sale securities and included within 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. Gains and losses on available-for-sale securities are recorded based on the specific identification method. 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 Other expense, net in the Consolidated Statement of Operations. In addition, realized gains and losses are included in Other expense, net in the Consolidated Statement of Operations. Equity Investments The Company enters into certain strategic investments for the promotion of business and strategic objectives. The equity method of accounting is used if the Company’s ownership interest is greater than or equal to 20% but less than a majority or where the Company has the ability to exercise significant influence over operating and financial policies. The Company’s equity in the earnings or losses in equity-method investments is recognized in Other expense, net, in the Consolidated Statement of Operations. The Company accounts for investments in equity securities of other entities under the cost method of accounting if the Company’s ownership interest is less than 20% and the Company does not have the ability to exercise significant influence over operating and financial policies of the investee. Investments accounted for under the cost method of accounting are recorded within Other non-current assets in the Consolidated Balance Sheets and are also periodically analyzed to determine whether or not there are indicators of impairment. Variable Interest Entities The Company evaluates its investments and other significant relationships to determine whether any investee is a variable interest entity (‘‘VIE’’). If the Company concludes that an investee is a VIE, the Company evaluates its power to direct the activities of the investee, its obligation to absorb the expected losses of the investee and its right to receive the expected residual returns of the investee to determine whether the Company is the primary beneficiary of the investee. If the Company is the primary beneficiary of a VIE, the Company consolidates such entity and reflects the non-controlling interest of other beneficiaries of that entity. The Company does not consolidate any cost method investment or equity method investment entities. Fair Value of Financial Instruments The carrying amounts of cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value for all periods presented because of the short-term maturity of these assets and liabilities. The fair value of investments that are not accounted for under the equity method is based on appropriate market information. Inventories The Company values inventories at the lower of cost (first-in, first out) 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. 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. 64 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) 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 and equipment are carried at cost less accumulated depreciation and amortization. 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-five years. The majority of the Company’s machinery and equipment, software, and furniture and fixtures, are depreciated on a straight-line basis over a period of two to seven years. Leasehold improvements are amortized over the lesser of the estimated useful lives of the assets or the related lease terms. Business Combinations The application of acquisition accounting to a business combination requires that the Company identify the individual assets acquired and liabilities assumed and estimate the fair value of each. The fair value of assets acquired and liabilities assumed in a business acquisition are recognized at the acquisition date using a combination of valuation techniques, with the purchase price exceeding the fair values being recognized as goodwill. Determining fair value of identifiable assets, particularly intangibles, liabilities acquired and contingent obligations assumed requires management to make estimates. In certain circumstances, the allocations of the excess purchase price are based upon preliminary estimates and assumptions and subject to revision when the Company receives final information, including appraisals and other analyses. Accordingly, the measurement period for such purchase price allocations will end when the information, or the facts and circumstances, becomes available, but will not exceed twelve months. The Company will recognize measurement-period adjustments during the period of resolution, including the effect on earnings of any amounts that would have been recorded in previous periods if the accounting had been completed at the acquisition date. Goodwill and intangible assets often represent a significant portion of the assets acquired in a business combination. The Company recognizes the fair value of an acquired intangible apart from goodwill whenever the intangible arises from contractual or other legal rights, or when it can be separated or divided from the acquired entity and sold, transferred, licensed, rented or exchanged, either individually or in combination with a related contract, asset or liability. Intangible assets consist primarily of technology, customer relationships, and trade name and trademarks acquired in business combinations and in-process research and development (‘‘IPR&D’’). The Company’s assessment of IPR&D also includes consideration of the risk of the projects not achieving technological feasibility. Goodwill and Other Long-Lived Assets Goodwill is not amortized. Instead, it is tested for impairment on an annual basis or more frequently whenever events or changes in circumstances indicate that goodwill may be impaired. The Company performs an annual impairment test as of the first day of its fiscal fourth quarter. The Company uses qualitative factors to determine whether goodwill is more likely than not impaired and whether a quantitative test for impairment is considered necessary. If the Company concludes from the qualitative assessment that goodwill is more likely than not impaired, the Company is required to perform a quantitative approach to determine the amount of impairment. The Company is required to use judgment when applying the goodwill impairment test, including the identification of reporting units, assignment of assets, liabilities and 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 reporting units 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. If the Company’s stock price decreases significantly, goodwill could become impaired, which could result in a material charge and adversely affect the Company’s results of operations. IPR&D is an intangible asset accounted as an indefinite-lived asset until the completion or abandonment of the associated research and development effort. During the development period, the Company conducts an IPR&D impairment 65 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) test annually and whenever events or changes in facts and circumstances indicate that it is more likely than not that the IPR&D is impaired. Events which might indicate impairment include, but are not limited to, adverse cost factors, strategic decisions made in response to economic, market, and competitive conditions, and the impact of the economic environment the Company and on its customer base. 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. Other long-lived intangible assets are amortized over their estimated useful lives based on the pattern in which the economic benefits are expected to be received. 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. See Note 7, Goodwill and Other Intangible Assets, for additional disclosures related to the Company’s other intangible assets. 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/or a right of return and the Company provides resellers and original equipment manufacturers (‘‘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 and/or returns 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, historical and anticipated returns 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. Revenue from patent licensing arrangements is recognized when earned, estimable and realizable. The timing of revenue recognition is dependent on the terms of each license agreement and on the timing of sales of licensed products. The Company generally recognizes royalty revenue when it is reported to the Company by its licensees, which is generally one quarter in arrears from the licensees’ sales of licensed products. For licensing fees that are not determined by the licensees’ sales, the Company generally recognizes license fee revenue on a straight-line basis over the life of the license. Some of the Company’s revenue arrangements are multiple-element arrangements because they are generally comprised of product, software and support services or multiple distinct licenses. For multiple-element arrangements, the Company evaluates whether each deliverable should be accounted for as a separate unit of accounting. For multiple-element arrangements that include support or software elements, the Company analyzes whether tangible products containing software and non-software components function together and therefore should be excluded from industry-specific software revenue recognition guidance. For all multiple-element arrangements, the Company allocates revenue to each element, or the software elements as a group, based on the relative selling price determined in accordance with the Company’s normal pricing and discounting practices for the specific element when sold separately. For multiple-element license agreements that include more than one license to distinct technology that are separate units of accounting, the Company allocates revenue to each license based on the relative selling price of each deliverable. License fees related to existing technology with no 66 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) continuing performance obligations are generally recognized upon license commencement and other license fees are generally recognized on a straight-line basis over the life of the license. The Company primarily uses an estimate of selling price to allocate revenue for multiple-element license agreements based upon similar licenses, historical and estimated future sales volume, duration and market conditions. 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, with a small number of products having a warranty ranging up to ten years or more. 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. For warranties ten years or greater, including lifetime warranties, the Company uses the estimated useful life of the product to calculate the warranty exposure. 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 product 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 16, Legal Proceedings, for additional disclosures related to the Company’s litigation. Advertising Expense Advertising costs are expensed as incurred and amounted to $112 million, $89 million and $60 million in 2018, 2017 and 2016, respectively. These expenses are included in Selling, general and administrative (‘‘SG&A’’) in the Consolidated Statements of Operations. Research and Development Expense Research and development (‘‘R&D’’) expenditures are expensed as incurred. 67 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) 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 quarter, 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 in 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 dilutive outstanding employee stock options, restricted stock unit awards (‘‘RSUs’’), performance-based restricted stock unit awards (‘‘PSUs’’), rights to purchase shares of common stock under the Company’s Employee Stock Purchase Plan (‘‘ESPP’’) and shares issuable in connection with convertible debt. Stock-based Compensation The Company accounts for all stock-based compensation at fair value. Stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the vesting period. The fair values of all stock options granted are estimated using a binomial option-pricing model, and the fair values of all ESPP purchase rights are estimated using the Black-Scholes-Merton option-pricing model. Both the binomial and the Black-Scholes-Merton option-pricing models require the input of highly subjective assumptions. PSUs are granted to certain employees and vest only after the achievement of pre-determined performance metrics. Once the performance metrics are met, vesting of PSUs is subject to continued service by the employee. At the end of each reporting period, the Company evaluates the probability that PSUs will be earned. The Company records stock-based compensation expense based on the probability that the performance metrics will be achieved over the vesting period. Other Comprehensive Income (Loss), Net of Tax Other comprehensive income (loss), net of tax 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), net of tax is comprised of unrealized gains or losses on foreign exchange contracts and interest rate swap agreements designated as cash flow hedges, available-for-sale securities, foreign currency translation, and actuarial gains or losses related to pensions. Derivative Contracts The majority of the Company’s transactions are in U.S. dollars; however, some transactions are based in various foreign currencies. The Company purchases foreign exchange contracts to hedge the impact of foreign currency exchange fluctuations on certain underlying assets, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. The purpose of entering into these hedging transactions is to minimize the impact of foreign currency fluctuations 68 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) 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 speculative or trading purposes. The Company had foreign exchange contracts with commercial banks for British pound sterling, European euro, Japanese yen, Malaysian ringgit, Philippine peso, Singapore dollar and Thai baht, which had an aggregate notional amount of $4.37 billion and $2.79 billion at June 29, 2018 and June 30, 2017, 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. 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 are reported in cost of revenue and operating expenses, and presented within cash flows from operating activities. 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 to the Consolidated Financial Statements for all years presented. A change in the fair value of undesignated hedges is recognized in earnings in the period incurred and is reported in Other expense, net. See Note 4, Fair Value Measurements and Investments, and Note 5, Derivative Instruments and Hedging Activities, for additional disclosures related to the Company’s foreign exchange contracts. The Company accounts for its interest rate swaps as designated cash flow hedges to mitigate variations in interest payments under a portion of its LIBOR-based term loans due to variations in the LIBOR index. The Company pays interest monthly at a fixed rate and receives interest monthly at the LIBOR rate on the notional amount of the contract. The effective portion of the change in fair value of this designated cash flow hedge is deferred in Other comprehensive income (loss), net of tax, with any ineffective portion recognized in Other income (expense), net. See Note 5, Derivative Instruments and Hedging Activities, and Note 6, Debt, for further discussion on interest rate swaps. Pensions and Other Post-Retirement Benefit Plans The Company has defined benefit pension plans and other post-retirement 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 post-retirement 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 8, Pension and Other Post-Retirement Benefit Plans, for additional disclosures related to the Company’s pensions and other post-retirement benefit plans. Note 2. Recent Accounting Pronouncements Accounting Pronouncements Recently Adopted In January 2017, the Financial Accounting Standards Board (‘‘FASB’’) issued Accounting Standards Update (‘‘ASU’’) No. 2017-04, ‘‘Intangibles — Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment’’ (‘‘ASU 2017-04’’). ASU 2017-04 simplifies the test for goodwill impairment by removing Step 2 from the goodwill impairment test. Companies will now perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value not to exceed the total amount of goodwill allocated to that reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. As permitted by ASU 2017-04, the Company has elected to early adopt this standard for its fiscal 2018 goodwill impairment test, which was performed as of the first day of the Company’s fourth quarter, March 31, 2018. The adoption of this standard did not have a material impact on the Company’s Consolidated Financial Statements. 69 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) In August 2016, the FASB issued ASU No. 2016-15, ‘‘Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments’’ (‘‘ASU 2016-15’’). ASU 2016-15 provides amendments that address eight specific cash flow classification issues for which there exists diversity in practice: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. The Company adopted ASU 2016-15 in the second quarter of 2018 on a modified retrospective basis as required by the standard. The Company’s adoption of ASU 2016-15 did not have a material effect on the Company’s historical Consolidated Financial Statements. In March 2016, the FASB issued ASU No. 2016-09, ‘‘Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting’’ (‘‘ASU 2016-09’’). ASU 2016-09 simplifies several aspects of the accounting for stock-based payment transactions and states that, among other things, all excess tax benefits and tax deficiencies should be recognized as income tax expense or benefit in the income statement and an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. The Company adopted this standard in the first quarter of 2018 using the modified retrospective approach. This adoption resulted in a one-time net increase to beginning retained earnings of $70 million, consisting of a $58 million cumulative adjustment for the previously unrecognized windfall tax benefits related to previous vesting and exercises of stock-based awards, and a $19 million cumulative adjustment related to the change in accounting policy for estimated forfeitures and share cancellations, partially offset by a decrease of $7 million for the related tax impacts of change in forfeiture policy. In addition, upon adoption of the new standard in the Company’s first quarter of 2018, the Company began prospectively reflecting the tax deficiencies and benefits as an operating activity, rather than as a financing activity under the previous standard, in the Company’s Consolidated Statements of Cash Flows. For the year ended June 29, 2018, the Company recognized net excess tax benefits $78 million, as a component of Income tax expense (benefit). In July 2015, the FASB issued ASU No. 2015-11, ‘‘Inventory (Topic 330) - Simplifying the Measurement of Inventory’’ (‘‘ASU 2015-11’’), which dictates that an entity should measure inventory within the scope of this update at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company adopted this standard in the first quarter of 2018. The Company’s adoption of ASU 2015-11 did not have a material impact on its Consolidated Financial Statements. Recently Issued Accounting Pronouncements Not Yet Adopted In February 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (‘‘ASU’’) No. 2018-02, ‘‘Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income’’ (‘‘ASU 2018-02’’). ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the 2017 Act. Consequently, the amendments eliminate the stranded tax effects resulting from the 2017 Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the 2017 Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The amendments in this update also require certain disclosures about stranded tax effects. The Company early adopted this standard effective June 30, 2018, the beginning of the first quarter of 2019. The adoption of this standard did not have a material impact on the Company’s Consolidated Financial Statements. In August 2017, the FASB issued ASU No. 2017-12, ‘‘Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities’’ (‘‘ASU 2017-12’’). ASU 2017-12 simplifies hedge accounting through changes to both designation and measurement requirements. For hedges that qualify as highly effective, the new standard eliminates the requirement to separately measure and record hedge ineffectiveness, resulting in better alignment between the presentation of the effects of the hedging instrument and the hedged item in the financial statements. The Company adopted this standard 70 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) effective June 30, 2018, the beginning of the first quarter of 2019. The adoption of this standard did not have a material impact on the Company’s Consolidated Financial Statements. In May 2017, the FASB issued ASU No. 2017-09, ‘‘Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting’’ (‘‘ASU 2017-09’’). ASU 2017-09 provides clarification when a change to the terms or conditions of a share-based payment award must be accounted for as a modification. The new guidance requires modification accounting if the fair value, vesting condition or the classification of the award is not the same immediately before and after a change to the terms and conditions of the award. This ASU is effective prospectively and was adopted effective June 30, 2018, the beginning of the first quarter of 2019. The adoption of this standard did not have a material impact on the Company’s Consolidated Financial Statements. In March 2017, the FASB issued ASU No. 2017-07, ‘‘Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost’’ (‘‘ASU 2017-07’’). ASU 2017-07 requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The Company adopted this standard effective June 30, 2018, the beginning of the first quarter of 2019. The adoption of this standard did not have a material impact on the Company’s Consolidated Financial Statements. In January 2017, the FASB issued ASU No. 2017-01, ‘‘Business Combinations (Topic 805): Clarifying the Definition of a Business’’ (‘‘ASU 2017-01’’). ASU 2017-01 narrows the definition of a ‘‘business’’. This standard provides guidance to assist entities with evaluating when a set of transferred assets and activities is a business. The Company adopted this standard effective June 30, 2018, the beginning of the first quarter of 2019, and applied it prospectively to transactions occurring thereafter. The adoption of this standard did not have a material impact on the Company’s Consolidated Financial Statements. In October 2016, the FASB issued ASU No. 2016-16, ‘‘Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory’’ (‘‘ASU 2016-16’’). ASU 2016-16 removes the prohibition in the FASB ASC Topic 740 against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. The new standard is intended to reduce the complexity of accounting principles generally accepted in the United States (‘‘U.S. GAAP’’) and diversity in practice related to the tax consequences of certain types of intra-entity asset transfers, particularly those involving IP. The Company adopted this standard effective June 30, 2018, the beginning of the first quarter of 2019. The adoption of this standard did not have a material impact on the Company’s Consolidated Financial Statements. In June 2016, the FASB issued ASU No. 2016-13, ‘‘Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments’’ (‘‘ASU 2016-13’’). ASU 2016-13 seeks to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments, including trade receivables, and other commitments to extend credit held by a reporting entity at each reporting date. The amendments require an entity to replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects current expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, which for the Company is the first quarter of fiscal 2021. The Company is currently evaluating the impact this update will have on its Consolidated Financial Statements. In February 2016, the FASB issued ASU No. 2016-02, ‘‘Leases (Topic 842)’’ (‘‘ASU 2016-02’’). ASU 2016-02 supersedes ASC 840 ‘‘Leases’’. The amendments in this update require, among other things, that lessees recognize the following for all leases (unless a policy election is made by class of underlying asset to exclude short-term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use 71 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) of, a specified asset for the lease term. Based on the standard as originally issued, lessees and lessors were to apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. However, the FASB issued ASU 2018-11 on July 30, 2018, which allows entities to apply the provisions of ASC 842 at the effective date without adjusting comparative periods. The standard is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. As the Company plans for the adoption of this standard, the Company has completed its first phase of globally identifying its leases including the identification of embedded leases. The Company is in the process of identifying changes to its processes, internal controls and system requirements and configurations that would result from the new lease standard. The Company’s implementation efforts are progressing as planned. The Company expects to adopt this standard in the first quarter of fiscal 2020 and expects to elect the practical expedient to not present historical comparative information. The Company continues to evaluate the impact ASU 2016-02 will have on its Consolidated Financial Statements. In January 2016, the FASB issued ASU No. 2016-01, ‘‘Financial Instruments — Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities’’ (‘‘ASU 2016-01’’). ASU 2016-01 provides guidance related to accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments, including the requirement to measure certain equity investments at fair value with changes in fair value recognized in net income. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The Company adopted this standard effective June 30, 2018, the beginning of the first quarter of 2019. The adoption of this standard did not have a material impact on the Company’s Consolidated Financial Statements. In May 2014, the FASB issued ASU No. 2014-09, ‘‘Revenue from Contracts with Customers (Topic 606)’’ (‘‘ASC Topic 606’’), which amends the guidance in former ASC Topic 605, ‘‘Revenue Recognition’’ (‘‘ASC Topic 605’’), to provide a single, comprehensive revenue recognition model for all contracts with customers. ASC Topic 606 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 Company adopted the new standard effective June 30, 2018, the beginning of the first quarter of 2019, using the modified retrospective method, with the cumulative effect of initially applying the guidance recognized at the date of initial application. The implementation of the new standard will impact the recognition of the Company’s revenue and cost as follows: • Substantially all of the Company’s current revenue is from the sale of hardware products. The Company does not believe that there are any material changes to the timing or amount of revenue for these types of sales under the new standard as the majority of the Company’s revenue is recognized at a point in time. • For sales-based royalties, the Company will estimate and recognize revenue in the period the royalty-bearing sales occur as opposed to the existing treatment of recognizing revenue in the period the royalty report is received. This change will result in the acceleration of revenue recognition by one fiscal quarter as well as fluctuations between the estimated and actual reported sales-based royalties, which the Company does not expect to be material. • For other revenue streams such as multi-element transactions, software and IP licenses, these transactions are immaterial and the related changes to revenue recognition will not be material. • For assets recognized from costs incurred to obtain or fulfill a contract, the Company does not expect to have material capitalized fees for contracts where the amortization period is greater than one year. The Company will continue to expense these costs as incurred. • The Company’s revenue disclosures will expand and may require judgment in certain areas. The adoption of the new revenue standard resulted in a post-tax adjustment of approximately $54 million to increase the beginning retained earnings for fiscal year 2019 for uncompleted contracts for which revenue will not be recognized in 72 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) the future periods under ASC Topic 606. The Company continues to evaluate the effect that ASC Topic 606 will have on its Consolidated Financial Statements, including the impact on income tax expense and related balance sheet accounts. Changes to the Company’s processes, internal controls and systems as a result of the adoption of this new revenue standard were not significant. Note 3. Supplemental Financial Statement Data Accounts receivable, net From time to time, in connection with factoring agreements, the Company sells trade accounts receivable without recourse to third party purchasers in exchange for cash. During 2018, the Company sold trade accounts receivable and received cash proceeds of $57 million. The discounts on the trade accounts receivable sold during 2018 were not material and were recorded within Other expense, net in the Consolidated Financial Statements. During 2017, the Company did not sell any trade accounts receivable.

U.S. Government agency and international government securities are valued using a market approach which is based on observable inputs including market interest rates from multiple pricing sources. Foreign Exchange Contracts. The Company’s foreign exchange contracts are short-term contracts to hedge the Company’s foreign currency risk. Foreign exchange contracts are valued using an income approach that is based on a present value of future cash flows model. The market-based observable inputs for the model include forward rates and credit default swap rates. For more information on the Company’s foreign exchange contracts, see Note 5, Derivative Instruments and Hedging Activities. Derivative assets and liabilities are reflected in the Company’s Consolidated Balance Sheet under Other current assets and Accrued expenses, respectively. Interest Rate Swaps. The Company’s interest rate swaps are long-term contracts to hedge the Company’s variable rate debt risk. Interest rate swaps are valued based on estimated present value of future cash flows model. The market-based observable inputs for the model include interest rate curves and credit valuation adjustments. Assets and Liabilities Measured at Fair Value on a Recurring Basis Using Significant Unobservable Inputs (Level 3) Exchange Options. The Company’s 2020 Convertible Notes (as defined in Note 6, Debt) were bifurcated into a debt host and exchange option for accounting purposes. The exchange options are accounted for as derivative liabilities because they are predominantly settled in cash. The fair value measurement of the exchange options arising from the Company’s 2020 Convertible Notes, which are not actively traded, is determined using unobservable inputs (Level 3). These inputs include (i) the estimated amount and timing of settlement of the underlying debt; (ii) the probability of the achievement of the factor(s) on which the settlement is based; (iii) the risk-adjusted discount rate based on the expected term to maturity of the debt; and (iv) the economic incentive for holders to exercise their exchange option. Significant increases or decreases in any of those inputs in isolation could result in a significantly lower or higher fair value measurement. During 2018 and 2017, the Company had no transfers of financial assets and liabilities between levels. Available-for-Sale Securities The cost basis of the Company’s investments classified as available-for-sale securities, individually and in the aggregate, approximated its fair value as of June 29, 2018 and June 30, 2017. 79 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Financial Instruments Not Carried at Fair Value The carrying value of the Company’s revolving credit facility approximates its fair value given the revolving nature of the balance and the variable market interest rate. For financial instruments where the carrying value (which includes principal adjusted for any unamortized issuance costs, and discounts or premiums) differs from fair value (which is based on quoted market prices), the following table represents the related carrying value and fair value for each of the Company’s outstanding financial instruments. Each of the financial instruments presented below was categorized as Level 2 for all periods presented, based on the frequency of trading immediately prior to the end of the fourth quarter of 2018 and the fourth quarter of 2017, respectively.

Equity Method Investments The Company has joint venture investments with Toshiba Memory Corporation and with Unisplendour Corporation Limited and Unissoft (Wuxi) Group Co. Ltd. (‘‘Unis’’). See Note 9, Commitments, Contingencies and Related Parties, for further discussion regarding these joint ventures. Cost Method Investments From time to time, the Company enters into certain strategic investments for the promotion of business and strategic objectives. The Company reports these investments under the cost method of accounting as it does not have a significant influence over the operations of these investees. These investments consist of debt and equity securities of privately-held companies that do not have a readily determinable fair value and are carried at historical cost. The Company assesses these securities for indications of other-than-temporary impairments. In 2018 and 2017, the Company recorded impairment charges and losses related to the sale of these cost method investments of $17 million and $55 million, respectively, which were included in Other expense, net in the Consolidated Statements of Operations. There were no impairments in 2016 related to these investments. As of June 29, 2018 and June 30, 2017, these investments aggregated $39 million and $91 million, respectively, and are reported under Other non-current assets in the Consolidated Balance Sheets. 80 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Note 5. Derivative Instruments and Hedging Activities As of June 29, 2018, the Company had outstanding foreign exchange forward contracts that were designated as either cash flow hedges or non-designated hedges. The contract maturity dates of these foreign exchange forward contracts do not exceed 12 months. In addition, the Company had outstanding interest rate swaps that were designated as cash flow hedges. The Company determined the ineffective portion and the amount excluded for effectiveness testing associated with its cash flow hedges to be immaterial to the Consolidated Financial Statements for 2018, 2017 and 2016. As of June 29, 2018, the amount of existing net gains related to cash flow hedges recorded in AOCI was $2 million, of which the majority is expected to be reclassified to earnings over the next twelve months. In addition, as of June 29, 2018, the Company did not have any foreign exchange forward contracts with credit-risk-related contingent features. Changes in fair values of the non-designated foreign exchange contracts are recognized in other income (expense), net and are largely offset by corresponding changes in the fair values of the foreign currency denominated monetary assets and liabilities. During 2018, 2017 and 2016, total net realized and unrealized transaction and foreign exchange contract currency gains and losses were not material to the Company’s Consolidated Financial Statements. See Note 4, Fair Value Measurements and Investments, for additional disclosures related to the fair value of the Company’s foreign exchange forward contracts. Netting Arrangements Under certain provisions and conditions within agreements with counterparties to the Company’s foreign exchange forward contracts, subject to applicable requirements, the Company has the right of offset associated with the Company’s foreign exchange forward contracts and is allowed to net settle transactions of the same currency with a single net amount payable by one party to the other. As of June 29, 2018 and June 30, 2017, the effect of rights of offset was not material and the Company did not offset or net the fair value amounts of derivative instruments in its Consolidated Balance Sheets. 81 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Note 6.

In February 2018, the Company entered into an amendment to the credit agreement entered into on April 29, 2016 (as amended, the ‘‘Credit Agreement’’), to provide for, among other things, (i) the issuance of a new $5.02 billion of term loan A-1 due 2023 (the ‘‘Term Loan A-1’’), (ii) a new $2.25 billion revolving credit facility maturing in 2023 (the ‘‘Revolving Facility’’), which replaced the Company’s prior $1.50 billion revolving credit facility maturing in 2021, (iii) modifications to the restrictive and financial maintenance covenants, to provide more flexibility and increased incremental debt capacity, (iv) amendments of the applicable varying interest rate margins to be based on the Company’s corporate credit ratings as described in the indenture, and (v) upon the occurrence of certain circumstances, a release of the security and guarantees as well as further covenant flexibility and increased incremental debt capacity. The Company used a portion of the proceeds of the Term Loan A-1 to repay in full its previous variable interest rate Term Loan A in the principal amount of $4.02 billion. The Term Loan A-1 bears interest at a per annum rate equal to, at the Company’s option, either an adjusted London Interbank Offered Rate (‘‘LIBOR’’) rate, subject to a 0.00% floor, plus an applicable margin varying from 1.125% to 2.000% or a base rate plus an applicable margin varying from 0.125% to 1.000%, in each case depending on the Company’s corporate credit ratings. Currently the Company has selected the LIBOR rate option, and the applicable rate was 3.59% as of June 29, 2018. Principal payments are due in quarterly installments of (i) 0.625% per quarter from June 2018 through March 2019 and (ii) 1.25% per quarter from June 2019 through December 2022, with the remaining balance payable on February 27, 2023. The Term Loan A-1 issuance costs are amortized to interest expense over the term of the loan, and as of June 29, 2018, issuance costs of $8 million remained unamortized. In May 2017, the Company entered into an interest rate swap for $1.00 billion notional amount which it has designated as a cash flow hedge to mitigate variations in interest payments under a portion of its LIBOR-based term loans due to variations in the LIBOR index. Under the agreement, the Company pays interest monthly at a fixed rate of 1.66% and 82 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) receives a LIBOR rate on the notional amount of the contract through May 2020. In addition, in April 2018, the Company entered into an interest rate swap for $1.00 billion notional amount which it has designated as a cash flow hedge to mitigate variations in interest payments under a portion of its LIBOR-based term loans due to variations in the LIBOR index. Under the agreement, the Company pays interest monthly at a fixed rate of 2.75% and receives a LIBOR rate on the notional amount of the contract through February 2023. Proceeds of $500 million were drawn under the Revolving Facility and were used to fund a voluntary partial prepayment of the Company’s existing U.S. Dollar denominated term B-3 loans (‘‘U.S. Term Loan B-3’’). Loans under the Revolving Facility bear interest, at the Company’s option, at either LIBOR plus an applicable margin varying from 1.125% to 2.000% or a base rate plus an applicable margin varying from 0.125% to 1.000%, in each case depending on the Company’s corporate credit ratings. Currently the Company has selected the LIBOR rate option, and the applicable interest rate was 3.59% as of June 29, 2018. The Company will also pay an unused commitment fee on the Revolving Facility ranging from 0.120% to 0.350% based on the Company’s corporate credit ratings as described in the indenture, with an initial fee of 0.250%. As of June 29, 2018, the Company had $1.75 billion of additional borrowing availability under the Revolving Facility. In November 2017, the Company borrowed $2.96 billion under U.S. Term Loan B-3 under its Credit Agreement and used the proceeds of this new loan to prepay in full the U.S. Term Loan B-2 previously outstanding under the Credit Agreement. During the year ended June 29, 2018, the Company funded a voluntary partial prepayment of $500 million, using proceeds from the Revolving Facility. In May 2018, the Company borrowed $2.46 billion under U.S. Term Loan B-4 under its Credit Agreement and used the proceeds of this new loan to prepay in full the U.S. Term Loan B-3 previously outstanding under the Credit Agreement. The U.S. Term Loan B-4 has an interest rate equal to, at the Company’s option, either an adjusted LIBOR rate, subject to a 0.00% floor, plus 1.75% or a base rate plus 0.75%. Currently the Company has selected the LIBOR rate option, and the applicable interest rate was 3.84% as of June 29, 2018. Principal payments on U.S. Term Loan B-4 of 0.25% are due quarterly and began on June 29, 2018 with the balance due on April 29, 2023. The U.S. Term Loan B-4 issuance costs are amortized to interest expense over the term of the loan and as of June 29, 2018, issuance costs of $1 million remained unamortized. The Revolving Facility, Term Loan A-1 and Term Loan B-4 are unconditionally guaranteed by each of the guarantors under the Credit Agreement and are secured on a first-priority basis (subject to permitted liens) by a lien on the same collateral that secure the other loans under the Credit Agreement; provided that the security and guarantees will be automatically suspended upon certain conditions. The Company assumed the 0.5% convertible senior notes due November 15, 2020 (the ‘‘2020 Convertible Notes’’) in connection with its acquisition of SanDisk Corporation (‘‘SanDisk’’), pursuant to an Agreement and Plan of Merger (the ‘‘Merger’’), on May 12, 2016 (the ‘‘SanDisk Closing Date’’). As of June 29, 2018, $35 million principal amount of the 2020 Convertible Notes was outstanding and had a conversion rate of 10.9006 units of reference property per $1,000 principal amount of the 2020 Convertible Notes, corresponding to 2.6020 shares of the Company’s common stock and $735.79 of cash, subject to adjustments under the indenture. The 2020 Convertible Notes are not currently exchangeable into reference property. The 2020 Convertible Notes were bifurcated into a debt host and exchange option for accounting purposes. The exchange options are accounted for as a derivative liability because they are predominantly settled in cash. Changes in the fair value of the exchange options are reported, and will be reported until the Company extinguishes the related debt, in Other expense, net in the Consolidated Statements of Operations. The exchange options are measured and reported at fair value on a recurring basis, within Level 3 of the fair value hierarchy. The fair value of the unredeemed and unsettled exchange options is reported in Accrued expenses and Other liabilities in the Consolidated Balance Sheets. See Note 4, Fair Value Measurements and Investments, for additional disclosures related to the fair values of the exchange options. For 2018, the change in the fair value of the outstanding exchange options related to the 2020 Notes resulted in an immaterial loss. 83 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) In February 2018, the Company issued $1.10 billion aggregate principal amount of convertible senior notes due February 1, 2024 (the ‘‘2024 Convertible Notes’’). The 2024 Convertible Notes bear interest at an annual rate of 1.50% with interest payable on February 1 and August 1 of each year. The Company is not required to make principal payments on the 2024 Convertible Notes prior to the maturity date. The 2024 Convertible Notes are jointly and severally guaranteed by certain material domestic subsidiaries of the Company. The 2024 Convertible Notes are convertible into cash, shares of the Company’s common stock, or a combination thereof at an initial conversion price of approximately $121.91 per share of common stock. Holders of the 2024 Convertible Notes may freely convert their 2024 Convertible Notes on or after November 1, 2023 until the close of business on the business day immediately preceding the maturity date. Prior to November 1, 2023, holders may convert their 2024 Convertible Notes based on variations in market price of the Company’s common stock in relation to the conversion price or the trading price of the 2024 Convertible Notes or upon the occurrence of specified corporate events. On or after February 5, 2021, the Company may redeem all or part of the 2024 Convertible Notes, at its option, if the market price of the Company’s stock achieves certain levels. The Company separately accounts for the liability and equity components of the 2024 Convertible Notes. The value of the liability component as of the date of issuance was recognized at the present value of its cash flows using a discount rate of 4.375%, the Company’s borrowing rate at the date of the issuance for a similar debt instrument without the conversion feature, resulting in a debt discount of $165 million, which was allocated to equity as the value of the conversion feature. The 2024 Convertible Notes debt issuance costs were approximately $18 million, of which $15 million was allocated to the debt component and $3 million was allocated to equity. The debt discount and issuance costs are amortized to interest expense over the term of the 2024 Convertible Notes. As of June 29, 2018, debt discount and issuance cost of $169 million remained unamortized. In February 2018, the Company issued $2.30 billion aggregate principal amount of senior unsecured notes due February 15, 2026 (the ‘‘2026 Senior Unsecured Notes’’). The 2026 Senior Unsecured Notes bear interest at an annual rate of 4.750% with interest payable on February 15 and August 15 of each year. The Company is not required to make principal payments on the 2026 Senior Unsecured Notes prior to the maturity date. The 2026 Senior Unsecured Notes are jointly and severally guaranteed by certain material domestic subsidiaries of the Company. The 2026 Senior Unsecured Notes issuance costs are amortized to interest expense over the term of the 2026 Senior Unsecured Notes and as of June 29, 2018, issuance costs of $20 million remained unamortized. In February and March, 2018, the Company completed the redemption of all of its outstanding 7.375% senior secured notes due 2023 in the aggregate principal amount of $1.875 billion (the ‘‘2023 Notes’’) and the tender offer and redemption and settlement of all of its outstanding 10.50% senior unsecured notes due 2024 in the aggregate principal amount of $3.350 billion (the ‘‘2024 Notes’’ and collectively with the 2023 Notes, the ‘‘Redeemed Notes’’), including an aggregate of $720 million of ‘‘make-whole’’ and tender premiums required for the tender offer of the 2024 Notes and the optional redemption of the Redeemed Notes in accordance with the applicable indentures and accrued interest through the applicable redemption dates. In November 2017, the Company settled in full the principal amounts of the Euro Term Loan B-2, plus accrued interest, using cash on hand. In connection with the settlements of the various debt instruments described above, in 2018, the Company recognized an aggregate loss on debt extinguishment of $899 million, consisting of $720 million of ‘‘make-whole’’ and tender premiums and $179 million of unamortized issuance costs. In 2017, the Company incurred losses on the extinguishment of debt of $274 million. The Credit Agreement requires the Company to comply with certain financial covenants, such as a leverage ratio and an interest coverage ratio. As of June 29, 2018, the Company was in compliance with all financial covenants. In addition, the Credit Agreement requires the Company to comply with customary covenants that limit or restrict the Company’s and its subsidiaries’ ability to incur liens and indebtedness; make certain restricted payments, acquisitions, investments, loans and guarantees; and enter into certain transactions with affiliates, mergers and consolidations. In addition, the indentures 84 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) governing the 2026 Senior Unsecured Notes and the 2024 Convertible Notes contain restrictive covenants that limit the Company’s and its subsidiaries’ ability to, among other things, consolidate, merge or sell all or substantially all of their assets; create liens; and incur, assume or guarantee additional indebtedness.

On August 25, 2017, the Company acquired substantially all the assets of Upthere, Inc., a cloud services company. These acquisitions are primarily intended to help meet the evolving needs of customers, while driving long-term growth for the Company's existing data center and client solution products over the long term. The aggregate purchase price of acquisitions during the year ended June 29, 2018 was $100 million in cash, with net assets acquired primarily consisting of developed technology and other intangible assets, of which $61 million was allocated to goodwill. Goodwill is primarily attributable to the benefits the Company expects to derive from diversifying product offerings to its Data Center Devices and Solutions and Client Solutions end markets as well as the acquired workforce. Goodwill is expected to be deductible for tax purposes because the acquisitions were structured as asset acquisitions but accounted for as business combinations. Concurrent with these acquisitions, the Company received $36 million in proceeds on previously outstanding notes receivable due from these acquired entities. 85 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) During the year ended June 29, 2018, the expenses incurred by the Company related to these acquisitions were immaterial and are primarily included within Selling, general and administrative expenses in the Consolidated Statements of Operations. Revenues and earnings related to these acquisitions was not material. The purchase price adjustments in 2017 resulted from adjustments to the assessment of fair value for certain acquired intangible assets; inventory; property, plant and equipment; and a portion of the deferred tax liability related to the Merger.

IPR&D is initially accounted for as an indefinite-lived intangible asset. Once a project reaches technological feasibility, the Company reclassifies the balance to existing technology and begins to amortize the intangible asset over its estimated useful life. During 2018, two IPR&D projects reached technological feasibility totaling $616 million and commenced amortization over an estimated useful life of 4 years. During 2018 and 2017, the Company did not record any impairment charges related to intangible assets. During 2016, the Company recorded $36 million of impairment charges related to intangible assets, which are recorded in Employee termination, asset impairment and other charges within the Consolidated Statements of Operations. The impairment charges primarily relate to acquired IPR&D projects that were abandoned and resulted in full impairment. 86 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Intangible assets are amortized over the estimated useful lives based on the pattern in which the economic benefits are expected to be received.

Management in Japan then matches the benefit payments to bond ratings that are ‘‘AA’’ or higher which 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. The Company’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 63% in debt securities, 34% in equity 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. 89 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Fair Value Measurements The following tables present the Japanese defined benefit pension plans’ major asset categories and their associated fair values as of June 29, 2018 and June 30, 2017: June 29, 2018 Level 1 Level 2 Level 3 Total (in millions) Equity: Equity commingled/mutual funds(1)(2) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $— $ 68 $— $ 68 Fixed income: Fixed income commingled/mutual funds(1)(3) . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Assets held in defined benefit plans in the Philippines, Taiwan and Thailand were immaterial and are not presented in the above tables. There were no significant movements of assets between any level categories in 2018, 2017 or 2016. 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. 90 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Cash equivalents 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 The Company’s expected employer contributions for 2019 and annual benefit payments over the next 5 years for its Japanese defined benefit pension plans are not expected to be material. Note 9. Commitments, Contingencies and Related Parties Flash Ventures The Company’s business ventures with Toshiba Memory Corporation (‘‘TMC’’) consist of three separate legal entities: Flash Partners Ltd. (‘‘Flash Partners’’), Flash Alliance Ltd. (‘‘Flash Alliance’’), and Flash Forward Ltd. (‘‘Flash Forward’’), collectively referred to as ‘‘Flash Ventures’’. The Company has a 49.9% ownership interest and TMC has a 50.1% ownership interest in each of these entities. Through Flash Ventures, the Company and TMC collaborate in the development and manufacture of flash-based memory wafers, which are manufactured by TMC at its wafer fabrication facilities located in Yokkaichi, Japan, using semiconductor manufacturing equipment individually owned or leased by each Flash Ventures entity. Each Flash Ventures entity purchases wafers from TMC at cost and then resell those wafers to the Company and TMC at cost plus a markup. Flash Partners. Flash Partners was formed in 2004 in connection with the construction of TMC’s ‘‘Fab 3’’ 300- millimeter wafer fabrication facility located in Yokkaichi, Japan. Flash Alliance. Flash Alliance was formed in 2006 in connection with the construction of TMC’s ‘‘Fab 4’’ 300- millimeter wafer fabrication facility located in Yokkaichi, Japan. Flash Forward. Flash Forward was formed in 2010 in connection with the construction of TMC’s ‘‘Fab 5’’ 300- millimeter wafer fabrication facility located in Yokkaichi, Japan. Fab 5 was built in two phases of approximately equal size. New Fab 2. The Company has a facility agreement with TMC related to the construction and operation of TMC’s ‘‘New Fab 2’’ 300-millimeter wafer fabrication facility located in Yokkaichi, Japan. New Fab 2 is primarily intended to provide additional clean room space to convert a portion of 2-dimensional (‘‘2D’’) flash-based wafer production capacity to 3-dimensional (‘‘3D’’) flash-based wafer production capacity. Production of flash-based wafers in New Fab 2 started in 2016. Fab 6. In December 2017, the Company entered into a facility agreement with TMC related to the construction and operation of a new 300-millimeter wafer fabrication facility in Yokkaichi, Japan, referred to as ‘‘Fab 6’’, which is primarily intended to provide clean room space to continue the transition of the parties’ existing 2D flash-based wafer capacity to 3D flash-based wafer production capacity. The Company is committed to 50% of Fab 6’s start-up costs, as well as 50% of approved Flash Ventures investments in manufacturing equipment for Fab 6. The Company accounts for its ownership position of each entity within Flash Ventures under the equity method of accounting. The financial and other support provided by the Company in all periods presented was either contractually required or the result of a joint decision to expand wafer capacity, transition to new technologies or refinance existing equipment lease commitments. Entities within Flash Ventures are variable interest entities (‘‘VIEs’’). The Company evaluated whether it is the primary beneficiary of any of the entities within Flash Ventures for all periods presented and determined that it is not the primary beneficiary of any of the entities within Flash Ventures because it does not have a controlling financial interest in any of those entities. In determining whether the Company is the primary beneficiary, the Company analyzed the primary purpose and design of Flash Ventures, the activities that most significantly impact Flash Ventures’ economic performance, and whether the Company had the power to direct those activities. The Company concluded, based upon its 49.9% ownership, the voting structure and the manner in which the day-to-day operations are conducted for each entity within Flash Ventures, that the Company lacked the power to direct most of the activities that most significantly impact the economic performance of each entity within Flash Ventures. 91 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The following table presents the notes receivable from, and equity investments in, Flash Ventures as of June 29, 2018 and June 30, 2017: June 29, 2018 June 30, 2017 (in millions) Notes receivable, Flash Partners . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 767 $ 264 119 Notes receivable, Flash Alliance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 379 Notes receivable, Flash Forward . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 187 Investment in Flash Partners . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 279 Investment in Flash Alliance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 112 Investment in Flash Forward . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

For all reporting periods presented, no loans were past due and no loan impairments were recorded. The Company’s notes receivable from each Flash Ventures entity, denominated in Japanese yen, are secured by equipment owned by that Flash Ventures entity. The Company assesses financing receivable credit quality through financial and operational reviews of the borrower and creditworthiness, including credit rating agency ratings, of significant investors of the borrower, where material or known. There were no impairments in 2018, 2017, or 2016. As of June 29, 2018 and June 30, 2017, the Company had accounts payable balances due to Flash Ventures of $259 million and $206 million, respectively.

The Company is committed to purchase its provided three-month forecast of Flash Ventures’ flash-based wafer supply, which generally equals 50% of Flash Ventures’ output. The Company is not able to estimate its total wafer purchase commitment obligation beyond its rolling three-month purchase commitment because the price is determined by reference to the future cost of producing the semiconductor wafers. In addition, the Company is committed to fund 49.9% to 50.0% of each Flash Ventures entity’s investments to the extent that each Flash Ventures entity’s operating cash flow is insufficient to fund these investments. Inventory Purchase Commitments with Flash Ventures. Purchase orders placed under Flash Ventures for up to three months are binding and cannot be canceled. 92 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Research and Development Activities.

Customer Concentration and Credit Risk The Company sells its products to computer manufacturers, resellers and retailers throughout the world. For each of 2018, 2017 and 2016, no customer accounted for 10% or more of the Company’s net revenue. For 2018, 2017 and 2016, the Company’s top 10 customers accounted for 42%, 36%, and 43%, respectively, of the Company’s net revenue. 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. As of June 29, 2018, two customers, Apple, Inc. and Dell Inc., accounted for 13% and 10%, respectively, of the Company’s net accounts receivable. As of June 30, 2017, one customer, Dell Inc., accounted for 11% of the Company’s net accounts receivable. As of June 29, 2018 and June 30, 2017, the Company had net accounts receivable of $2.20 billion and $1.95 billion, respectively, and reserves for potential credit losses were not material as of each period. 96 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) 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. Supplier Concentration All of the Company’s flash memory system products require silicon wafers for the memory and controller components. The Company’s flash memory wafers are currently supplied almost entirely from Flash Ventures and the controller wafers are all manufactured by third-party sources. The failure of any of these sources to deliver silicon wafers could have a material adverse effect on the Company’s business, financial condition and results of operations. In addition, some key components are purchased from single source vendors for which alternative sources are currently not available. Shortages could occur in these essential materials due to an interruption of supply or increased demand in the industry. If the Company was unable to procure certain of such materials, the Company’s sales could decline, which could have a material adverse effect upon its results of operations. The Company also relies on third-party subcontractors to assemble and test a portion of its products. The Company does not have long-term contracts with some of these subcontractors and cannot directly control product delivery schedules or manufacturing processes. This could lead to product shortages or quality assurance problems that could increase the manufacturing costs of the Company’s products and have material adverse effects on the Company’s operating results. Note 11. Western Digital Corporation 401(k) Plan The Company maintains the Western Digital Corporation 401(k) Plan (the ‘‘Plan’’). The Plan covers substantially all domestic employees, subject to certain eligibility requirements. Eligible employees receive employer matching contributions immediately upon hire unless the individual is covered by a collective bargaining agreement, provides services as a consultant, intern, independent contractor, leased or temporary employee, or otherwise is not treated as a common-law employee. Eligible employees are generally able to contribute up to 30% of their eligible compensation on a pre-tax basis or 10% of their eligible compensation on an after-tax basis subject to Internal Revenue Service (‘‘IRS’’) limitations. The Company makes a basic matching contribution equal to 50% of the each eligible participant’s contribution that does not exceed 6% of the eligible participant’s annual compensation in the year of contribution. The Company’s employer matching contributions vest over a two-year graded period. The Company may suspend matching contributions at any time at its discretion. Contributions, including the Company’s matching contribution to the Plan, are recorded as soon as administratively possible after the Company makes payroll deductions from Plan participants. For 2018, 2017 and 2016, the Company made Plan contributions of $35 million, $36 million and $20 million, respectively. Note 12. Shareholders’ Equity 2017 Performance Incentive Plan The types of awards that may be granted under the Western Digital Corporation Amended and Restated 2017 Performance Incentive Plan (‘‘2017 Performance Incentive Plan’’) include stock options, SARs, RSUs, PSUs, 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 2017 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 2017 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 2017 Performance Incentive Plan is ten years after the grant date of the award. RSUs granted under the 2017 Performance Incentive Plan typically vest over periods ranging from one to four years from the date of grant. PSUs are granted to certain employees and vest only after the achievement of pre-determined performance metrics and completion of requisite 97 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) service periods. Once the performance metrics are met, vesting of PSUs is generally subject to continued service by the employee. To the extent available, the Company issues shares out of treasury stock upon the vesting of awards, the exercise of employee stock options and the purchase of shares pursuant to the ESPP. Outstanding RSU and PSU awards have dividend equivalent rights which entitle holders of such outstanding awards to the same dividend value per share as holders of common stock. Dividend equivalent rights are subject to the same vesting and other terms and conditions as the corresponding unvested RSUs and PSUs. Dividend equivalent rights are accumulated and paid in additional shares when the underlying shares vest. As of June 29, 2018, the maximum number of shares of the Company’s common stock that was authorized for award grants under the 2017 Performance Incentive Plan was 80.5 million shares. Shares issued in respect of stock options and SARs granted under the 2017 Performance Incentive Plan count against the plan’s share limit on a one-for-one basis, whereas currently, shares issued in respect of any other type of award granted count against the plan’s share limit as 1.72 shares for every one share issued in connection with such award. The 2017 Performance Incentive Plan was extended in 2013 and will terminate on August 4, 2025 unless terminated earlier by the Company’s Board of Directors (the ‘‘Board’’). Employee Stock Purchase Plan Under the Company’s ESPP, eligible employees may authorize payroll deductions of up to 10% of their eligible compensation, subject to IRS limitations, 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. During 2018, 2017 and 2016, the Company issued 2.5 million, 2.3 million, and 1.3 million shares, respectively, for aggregate purchase amounts of $119 million, $105 million, and $68 million, respectively.

Fair Value Valuation Assumptions Stock Option Grants — 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. No options were granted in 2018. The fair value of stock options granted in 2017 and 2016 was estimated using the following weighted average assumptions: 2017 2016 Suboptimal exercise factor. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

ESPP — 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 generally granted on either June 1st or December 1st of each year.

In 2018, the Company repurchased 7.1 million shares for a total cost of $591 million. Subsequent to June 29, 2018 and through July 25, 2018, the Company repurchased an additional 0.8 million shares for a total cost of $61 million. On July 25, 2018, the Company’s Board of Directors authorized a new $5.00 billion share repurchase program that is effective through July 25, 2023, replacing all prior programs. 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. Subsequent to July 25, 2018 and through August 22, 2018, the Company repurchased an additional 5.9 million shares for a total cost of $404 million under this new program.

The 2017 Act includes a broad range of tax reform proposals affecting businesses, including a reduction in the U.S. federal corporate tax rate from 35% to 21%, a one-time mandatory deemed repatriation tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign earnings. For the year ended June 29, 2018, the Company has not finalized the accounting for the tax effects of the enactment of the 2017 Act. However, consistent with applicable SEC guidance, the Company has made a reasonable estimate of the effects on the Company’s existing deferred tax balances and the one-time mandatory deemed repatriation tax required by the 2017 Act and has recognized a provisional income tax expense of $1.57 billion for the one-time mandatory deemed repatriation tax and a provisional income tax benefit of $65 million related to the re-measurement of deferred tax assets and liabilities for the year ended June 29, 2018. For other elements of tax expense noted below, or where the Company has not made an election, the Company has not been able to make a reasonable estimate and continues to account for such items based on the provisions of the tax laws that were in effect immediately prior to the 2017 Act. As the Company finalizes the accounting for the tax effects of the enactment of the 2017 Act during the one-year measurement period permitted by applicable SEC guidance, the Company expects to reflect adjustments to the recorded provisional amounts and record additional tax effects of the 2017 Act. 102 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Additional information regarding the significant provisions of the 2017 Act that are expected to impact the Company is provided below. Re-measurement of deferred taxes The provisional income tax benefit of $65 million recorded for the year ended June 29, 2018 related to the re-measurements of the Company’s deferred tax balances and is based primarily on the rates at which the deferred tax assets and liabilities are expected to reverse in the current and future fiscal years, which are generally 29% and 22%, respectively. However, the Company is still analyzing certain aspects of the 2017 Act and refining the calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. The Company is also analyzing the impact of the 2017 Act to the existing valuation allowance assessments from both a federal and state tax perspective, which could potentially affect the realizability of the existing deferred tax assets. In calculating the provisional amount, the Company utilized an estimate of the expected reversals of certain tax assets and liabilities, which will be revised in future quarters during the one-year measurement period as additional information becomes available. The provisional income tax benefit for the year ended June 29, 2018 reflects a revision to the Company’s initial provisional estimate resulting in income tax expense of $23 million for refinements to the expected reversals of deferred tax assets and liabilities. Mandatory deemed repatriation tax In connection with the transition from a global to a territorial U.S. tax system, companies are required to pay a mandatory deemed repatriation tax. For the year ended June 29, 2018, the Company recorded a provisional amount for the mandatory deemed repatriation tax liability of $1.57 billion for foreign subsidiaries and $131 million of this amount is classified as a current tax liability. The calculation of the mandatory deemed repatriation tax liability is provisional and based upon preliminary estimates of post-1986 earnings and profits. In addition, the mandatory deemed repatriation tax is based on a provisional amount of foreign earnings held in cash and other specified assets, which are taxed at 15.5% and 8%, respectively, and is payable over an 8-year period. On August 1, 2018, U.S. Treasury issued proposed regulations as guidance for the mandatory deemed repatriation tax. The Company will continue to evaluate the impact of this guidance through the end of the one-year measurement period. As such, the provisional amount may change during the one-year measurement period when the Company finalizes the calculation of post-1986 foreign earnings and profits and the amount of foreign earnings held in cash or other specified assets. The provisional income tax expense for the year ended June 29, 2018 reflects a revision to the Company’s initial provisional estimate resulting in income tax benefits of $18 million for the required utilization of the 2018 generated foreign tax credits and $73 million for potential cash tax payments arising from certain unrecognized tax benefits that would partially offset the mandatory deemed repatriation tax. Although the mandatory deemed repatriation tax has removed U.S. federal taxes on distributions to the U.S., the Company continues to evaluate the expected manner of recovery to determine whether or not to continue to assert indefinite reinvestment on a part or all the foreign undistributed earnings. This requires the Company to re-evaluate the existing short and long-term capital allocation policies in light of the 2017 Act and calculate the tax cost that is incremental to the deemed repatriation tax (e.g., foreign withholding, state income taxes, and additional U.S. tax on currency transaction gains or losses) of repatriating cash to the U.S. While the provisional tax expense for the year ended June 29, 2018 is based upon an assumption that foreign undistributed earnings are indefinitely reinvested, the Company’s plan may change upon the completion of long-term capital allocation plans in light of the 2017 Act and completion of the calculation of the incremental tax effects on the repatriation of foreign undistributed earnings. In the event the Company determines not to continue to assert the permanent reinvestment of part or all of foreign undistributed earnings, such a determination could result in the accrual and payment of additional federal, foreign, state and local taxes. Deferred taxes on foreign earnings As a result of the shift to a territorial system for U.S. taxation, the new minimum tax on certain foreign earnings (‘‘global intangible low-tax income’’) provision of the 2017 Act imposes a tax on foreign earnings and profits in excess of a deemed return on tangible assets of foreign subsidiaries. This provision is effective for tax years beginning on or after January 1, 2018, which for the Company would be the fiscal year beginning on June 30, 2018 (fiscal year 2019). The Company has not 103 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) progressed sufficiently in the analysis of this provision to make an election either to account for the effects of this provision either as a component of future income tax expense in the period the tax arises or as a component of deferred taxes on the related investments. Accordingly, no deferred tax assets and liabilities have been established for timing differences between foreign U.S. GAAP income and foreign earnings and profits that would be expected to reverse under the new minimum tax in future years. Additionally, the Company has not yet completed the calculation of post-1986 foreign earnings and profits for the mandatory repatriation tax, which would be the starting point for the measurement of deferred tax assets and liabilities in order to record any provisional amounts. Undistributed Foreign Earnings The Company has previously asserted all of its unremitted earnings offshore were permanently reinvested and had not recorded any deferred taxes related to any outside basis differences associated with its foreign subsidiaries. The estimated remaining net undistributed earnings from foreign subsidiaries at June 29, 2018 is estimated to be approximately $17 billion. While the Company has included a provisional estimate of the mandatory deemed repatriation tax on these earnings, the Company is currently evaluating how the 2017 Act will impact the Company's existing assertion of indefinite reinvestment and determining a reasonable estimate of the remaining tax liability, if any, for any outside basis differences after consideration of the mandatory repatriation tax. As such, no change has been made with respect to this assertion for the year ended June 29, 2018. The Company will complete its analysis of the impact of the 2017 Act on its indefinite reinvestment assertion and record amounts, such as any remaining outside basis differences, foreign withholding taxes, state income taxes, and additional U.S. tax on currency transaction gains or losses, if necessary, during the measurement period. Deferred Taxes Temporary differences and carryforwards, which give rise to a significant portion of deferred tax assets and liabilities were as follows: Deferred tax assets: June 29, 2018 June 30, 2017 (in millions) Sales related reserves and accrued expenses not currently deductible. . . . . . . . . . . . . . . . . . . . . . . . . . $ Accrued compensation and benefits not currently deductible . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The valuation allowance increase in 2018 is primarily attributable to the 2018 generation of foreign net operating loss carryforwards of $54 million and state tax credits of $33 million, which the Company does not anticipate being able to utilize. The assessment of valuation allowances against deferred tax assets requires estimations and significant judgment. The Company continues to assess and adjust its valuation allowance based on operating results and market conditions. After weighing both the positive and negative evidence available, including but not limited to, earnings history, projected future outcomes, industry and market trends and the nature of each of the deferred tax assets, the Company determined that it is able to realize most of its deferred tax assets with the exception of certain loss and credit carryforwards. In addition to the deferred tax assets presented above, the Company had benefits related to net operating loss benefits from stock-based compensation deductions of $20 million as of June 30, 2017. The reduction in NOL benefits from stock-based compensation deductions was due to the adoption of ASU 2016-09 during the first quarter of 2018. See Part II, Item 8, Note 2, Recent Accounting Pronouncements, of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. Effective Tax Rate Under the 2017 Act, the reduction of the U.S. federal corporate tax rate from 35% to 21% is effective January 1, 2018, requiring companies to use a blended rate for their fiscal 2018 tax year by applying a pro-rated percentage of the number of days before and after the January 1, 2018 effective date. This results in the use of an estimated annual effective tax rate of approximately 28% for the Company’s U.S. federal corporate tax rate for fiscal year 2018. For fiscal year 2019 and beyond, the Company will utilize the enacted U.S. federal corporate tax rate of 21%.

Certain of the holidays may be extended if specific conditions are met. The net impact of these tax holidays and tax incentives was an increase to the Company’s net earnings by $519 million, or $1.69 per diluted share, $467 million, or $1.58 per diluted share, and $500 million, or $2.07 per diluted share, in 2018, 2017, and 2016, respectively. As of June 29, 2018, the Company had varying amounts of federal and state NOL/tax credit carryforwards that do not expire or, if not used, expire in various years. Following is a summary of the Company’s federal and state NOL/tax credit carryforwards and the related expiration dates of these NOL/tax credit carryforwards: Jurisdiction NOL/Tax Credit Carryforward Amount (in millions) Federal NOL (Pre 2017 Act Generation) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The Company expects the total amount of federal NOLs ultimately realized will be reduced by $448 million and state NOLs ultimately realized will be reduced by $435 million. The Company expects the total amount of federal credits ultimately realized will be reduced by $39 million and state tax credit carryforwards ultimately realized will be reduced by $550 million. The Company had varying amounts of foreign NOL carryforwards that do not expire or, if not used, expire in various years, depending on the country. The major jurisdictions that the Company receives foreign NOL carryforwards and the related amounts and expiration dates of these NOL carryforwards are as follows: Jurisdiction NOL Carryforward Amount (in millions) Japan . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Interest and penalties related to unrecognized tax benefits are recognized in liabilities recorded for uncertain tax positions and are recorded in the provision for income taxes. Accrued interest and penalties included in the Company’s liability related to unrecognized tax benefits as of June 29, 2018, June 30, 2017 and July 1, 2016 was $110 million, $89 million and $75 million, respectively.

The entire balance of unrecognized tax benefits as of June 29, 2018, June 30, 2017 and July 1, 2016, 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 2010 through 2017. The Company is no longer subject to examination by the IRS for periods prior to 2010, 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. In the major foreign jurisdictions, the Company could be subject to examination in China for calendar years 2008 through 2017, in Ireland for calendar years 2014 through 2017, in India for fiscal years 2013 through 2017, in Israel for fiscal years 2013 through 2017 and in Japan for fiscal years 2011 through 2017. The IRS previously completed its field examination of the Company’s federal income tax returns for fiscal years 2006 through 2009 and proposed certain adjustments. As previously disclosed, the Company received Revenue Agent Reports from the IRS, proposing adjustments relating to transfer pricing with the Company’s foreign subsidiaries and intercompany payable balances. The Company disagrees with the proposed adjustments and in September 2015, filed a protest with the IRS Appeals Office and received the IRS rebuttal in July 2016. The Company and the IRS Appeals Office did not reach a settlement on the disputed matters. On June 28, 2018, the IRS issued a statutory notice of deficiency with respect to the unagreed issues, seeking to increase the Company’s U.S. taxable income by an amount that would result in additional federal tax through fiscal year 2009 totaling approximately $516 million, subject to interest. The Company intends to file a Petition with the U.S. Tax Court. The Company believes that its tax positions are properly supported and will vigorously contest the position taken by the IRS. In September 2015, the IRS commenced an examination of the Company’s fiscal years 2010 through 2012. The Company believes that adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax examinations cannot be predicted with certainty. If any issues addressed in the Company’s tax examinations 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 29, 2018, it was not 107 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) 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.

Legal Proceedings 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 note, ‘‘WD’’ refers to Western Digital Corporation or one or more of its subsidiaries excluding HGST prior to the closing of the Company’s acquisition of HGST on March 8, 2012 (the ‘‘HGST Closing Date’’) and 110 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) SanDisk prior to the SanDisk 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; ‘‘SanDisk’’ refers to SanDisk Corporation or one or more of its subsidiaries as of the SanDisk Closing Date; and ‘‘the Company’’ refers to Western Digital Corporation and all of its subsidiaries on a consolidated basis including HGST and SanDisk. Intellectual Property Litigation In May 2016, Lambeth Magnetic Structures, LLC (‘‘Lambeth’’) filed a complaint with the U.S. District Court for the Western District of Pennsylvania against WD and certain of its subsidiaries alleging infringement of U.S. Patent No. 7,128,988. The complaint seeks unspecified monetary damages and injunctive relief. The ’988 patent, entitled ‘‘Magnetic Material Structures, Devices and Methods,’’ allegedly relates to a magnetic material structure for hard disk drive devices. The Company intends to defend itself vigorously in this matter. Antitrust In March 2011, a complaint was filed against SanDisk, SD-3C LLC, Panasonic Corporation, Panasonic Corporation of North America, Toshiba Corporation and Toshiba America Electronic Components, Inc. with the U.S. District Court for the Northern District of California. The lawsuit purports to be on behalf of a nationwide class of indirect purchasers of SD cards. The complaint asserts claims under federal antitrust laws and California antitrust and unfair competition laws, as well as common law claims. The complaint seeks damages, restitution, injunctive relief, and fees and costs. The plaintiffs allege that the defendants conspired to artificially inflate the royalty costs associated with manufacturing SD cards, which in turn allegedly caused the plaintiffs to pay higher prices for SD cards. In November 2015, the defendants filed a motion to dismiss the plaintiffs’ federal law claims. In October 2016, the District Court granted the defendants’ motion with leave to amend and the defendants filed a motion to dismiss the plaintiffs’ remaining claims. In July 2018, ten of the thirteen named plaintiffs voluntarily dismissed their claims against the defendants. Counsel for the remaining named plaintiffs are engaged in settlement discussions with counsel for the defendants. The case has been stayed pending these settlement discussions. The Company intends to defend itself vigorously in this matter. Securities Beginning in March 2015, SanDisk and two of its officers, Sanjay Mehrotra and Judy Bruner, were named in three putative class action lawsuits filed with the U.S. District Court for the Northern District of California. Two complaints are brought on behalf of a purported class of purchasers of SanDisk’s securities between October 2014 and March 2015, and one is brought on behalf of a purported class of purchasers of SanDisk’s securities between April 2014 and April 2015. The complaints generally allege violations of federal securities laws arising out of alleged misstatements or omissions by the defendants during the alleged class periods. The complaints seek, among other things, damages and fees and costs. In July 2015, the District Court consolidated the cases and appointed Union Asset Management Holding AG and KBC Asset Management NV as lead plaintiffs. The lead plaintiffs filed an amended complaint in August 2015. In January 2016, the District Court granted the defendants’ motion to dismiss and dismissed the amended complaint with leave to amend. In February 2016, the District Court issued an order appointing as new lead plaintiffs Bristol Pension Fund; City of Milford, Connecticut Pension & Retirement Board; Pavers and Road Builders Pension, Annuity and Welfare Funds; the Newport News Employees’ Retirement Fund; and Massachusetts Laborers’ Pension Fund (collectively, the ‘‘Institutional Investor Group’’). In March 2016, the Institutional Investor Group filed an amended complaint. In June 2016, the District Court granted the defendants’ motion to dismiss and dismissed the amended complaint with leave to amend. In July 2016, the Institutional Investor Group filed a further amended complaint. In June 2017, the District Court denied the defendants’ motion to dismiss. The Company intends to defend itself vigorously in this matter. Copyright In December 2011, the German Central Organization for Private Copying Rights (Zentralstelle für private Überspielungsrechte) (‘‘ZPÜ’’), an organization consisting of several copyright collecting societies, instituted arbitration proceedings against WD’s German subsidiary (‘‘WD Germany’’) before the Copyright Arbitration Board (‘‘CAB’’) claiming 111 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) copyright levies for multimedia hard drives, external hard drives and network hard drives sold or introduced into commerce in Germany by WD Germany from January 2008 through December 2010. In February 2013, WD Germany filed a declaratory relief action against ZPÜ in the Higher Regional Court of Munich (the ‘‘Higher Court’’), seeking an order from the Higher Court to determine the copyright levy issue. In May 2013, ZPÜ filed a counter-claim against WD Germany 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 in November 2011. In January 2015, the Higher Court ruled in favor of ZPÜ. In its ruling, the Higher Court declared that WD Germany must pay certain levies on certain products that it sold in Germany between January 2008 and December 2010. The judgment specified levy amounts on certain products sold from January 2008 through December 2010 and directed WD Germany to disclose applicable sales data to ZPÜ. The exact amount of the judgment had not been determined. ZPÜ and WD Germany filed appeals with the German Federal Court of Justice in February 2015. In March 2017, the German Federal Court of Justice rendered a judgment affirming ZPÜ’s claim concerning the disclosure of WD Germany’s sales data regarding HDDs sold between January 2008 and December 2010. The German Federal Court of Justice also set aside the Higher Court’s decision on the levy amounts and referred the case back to the Higher Court for further fact finding and decision on the levy amounts. In December 2014, ZPÜ submitted a pleading to the CAB seeking copyright levies for multimedia hard drives, external hard drives and network hard drives sold or introduced into commerce in Germany by WD Germany between January 2012 and December 2013. On or around June 22, 2018, Bitkom, an industry association, and ZPÜ entered into an agreement for regulating the obligation to pay compensation under copyright law in Germany for hard drives for the period beginning January 1, 2008. On or around June 29, 2018, the Company elected to join the agreement. Pursuant to the agreement, the Company and ZPÜ intend to dismiss the actions against each other following an accounting and payment of past liabilities. The entry into this agreement did not have a material impact on the Company’s financial condition, results of operations or cash flows. Other Matters In the normal course of business, the Company is subject to other legal proceedings, lawsuits and other claims. Although the ultimate aggregate amount of probable monetary liability or financial impact with respect to these other matters is subject to many uncertainties, 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, any monetary liability and financial impact to the Company from these other matters could differ materially from the Company’s expectations. Note 17. Separate Financial Information of Guarantor Subsidiaries The 2026 Senior Unsecured Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis, subject to certain customary guarantor release conditions, by certain 100% owned material domestic subsidiaries of the Company (or the ‘‘Guarantor Subsidiaries’’). The guarantee by a Guarantor Subsidiary will be released in the event of (i) the release of a Guarantor Subsidiary from its guarantee of indebtedness under the Credit Agreement or other indebtedness that would have required the Guarantor Subsidiary to guarantee the 2026 Senior Unsecured Notes, (ii) the sale, issuance or other disposition of capital stock of a Guarantor Subsidiary such that it is no longer a restricted subsidiary under the indenture governing the 2026 Senior Unsecured Notes, (iii) the sale of all or substantially all of a Guarantor Subsidiary’s assets, (iv) the Company’s exercise of its defeasance options under the indenture governing the 2026 Senior Unsecured Notes, (v) the dissolution or liquidation of a Guarantor Subsidiary or (vi) the sale of all the equity interest in a Guarantor Subsidiary. The Company’s other domestic subsidiaries and its foreign subsidiaries (collectively, the ‘‘Non-Guarantor Subsidiaries’’) do not guarantee the 2026 Senior Unsecured Notes. The following condensed consolidating financial information reflects the summarized financial information of Western Digital Corporation (‘‘Parent’’), the Guarantor Subsidiaries on a combined basis, and the Non-Guarantor Subsidiaries on a combined basis. 112 WESTERN DIGITAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Condensed Consolidating Balance Sheet As of June 29, 2018 Parent Guarantor Subsidiaries Non-Guarantor Subsidiaries Eliminations Total Company ASSETS Current assets: Cash and cash equivalents . . . . . . . . . . . . . . . . . . . . . . . . $ Accounts receivable, net . . . . . . . . . . . . . . . . . . . . . . . . .

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 (2013). 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 Report of Independent Registered Public Accounting Firm 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 29, 2018, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We are implementing an enterprise resource planning (‘‘ERP’’) system on a worldwide basis, which is expected to improve the efficiency of certain financial and related transactional processes. The gradual implementation is expected to occur in phases over the next several years. We have completed the implementation of certain processes, including the financial consolidation and reporting and supplier management processes, and have revised and updated the related controls. These changes did not materially affect our internal control over financial reporting. As we implement the remaining functionality under this ERP system over the next several years, we will continue to assess the impact on 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 124 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. Item 9B. Other Information None. 125 PART III Item 10.

These non-GAAP measures are not in accordance with, or an alternative for, measures prepared in accordance with GAAP and may be different from non-GAAP measures used by other companies. The company believes the presentation of these non-GAAP measures, when shown in conjunction with the corresponding GAAP measures, provides useful information to investors for measuring the company’s earnings performance and comparing it against prior periods. Specifically, the company believes these non-GAAP measures provide useful information to both management and investors as they exclude certain expenses, gains and losses that the company believes are not indicative of its core operating results or because they are consistent with the financial models and estimates published by many analysts who follow the company and its peers. As discussed further below, these non-GAAP measures exclude the amortization of acquired intangible assets, stock-based compensation expense, employee termination, asset impairment and other charges, acquisition-related charges, charges related to cost saving initiatives, convertible debt activity, debt extinguishment costs, other charges, and income tax adjustments, and the company believes these measures along with the related reconciliations to the GAAP measures provide additional detail and comparability for assessing the company’s results. These non-GAAP measures are some of the primary indicators management uses for assessing the company’s performance and planning and forecasting future periods. These measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. Free cash flow is a non-GAAP financial measure defined as cash flows provided by operating activities less purchases of property, plant and equipment, net of proceeds from sales of property, plant and equipment, and the activity related to Flash Ventures, net. The company considers free cash flow to be useful as an indicator of its overall liquidity, as the amount of free cash flow generated in any period is representative of cash that is available for strategic opportunities including, among others, investing in the company’s business, making strategic acquisitions, strengthening the balance sheet, repaying debt, paying dividends and repurchasing stock. As described above, the company excludes the following items from its non-GAAP measures: Amortization of acquired intangible assets. The company incurs expenses from the amortization of acquired intangible assets over their economic lives. Such charges are significantly impacted by the timing and magnitude of the company’s acquisitions and any related impairment charges. Stock-based compensation expense. Because of the variety of equity awards used by companies, the varying methodologies for determining stock-based compensation expense, the subjective assumptions involved in those determinations, and the volatility in valuations that can be driven by market conditions outside the company’s control, the company believes excluding stock-based compensation expense enhances the ability of management and investors to understand and assess the underlying performance of its business over time and compare it against the company’s peers, a majority of whom also exclude stock-based compensation expense from their non-GAAP results. Employee termination, asset impairment and other charges. From time-to-time, in order to realign the company’s operations with anticipated market demand or to achieve cost synergies from the integration of acquisitions, the company may terminate employees and/or restructure its operations. During the fiscal years ended June 29, 2018 and June 30, 2017, the company incurred charges related to restructuring actions as more fully described in Part II, Item 8, Note 15, Employee Termination, Asset Impairment and Other Charges, of the Notes to the Consolidated Financial Statements included in the Company’s Annual Report of Form 10-K for the year ended June 29, 2018. From time-to-time, the company may also incur charges from the impairment of intangible assets and other long-lived assets. These charges (including any reversals of charges recorded in prior periods) are inconsistent in amount and frequency, and the company believes are not indicative of the underlying performance of its business. Acquisition-related charges. In connection with the company’s business combinations, the company incurs expenses which it would not have otherwise incurred as part of its business operations. These expenses include third-party professional service and legal fees, third-party integration services, severance costs, non-cash adjustments to the fair value of acquired inventory, contract termination costs, and retention bonuses. The company may also experience other accounting impacts in connection with these transactions. These charges and impacts are related to acquisitions, are inconsistent in amount and frequency, and the company believes are not indicative of the underlying performance of its business. Charges related to cost saving initiatives. In connection with the transformation of the company’s business, the company has incurred charges related to cost saving initiatives which do not qualify for special accounting treatment as exit or disposal activities. These charges, which the company believes are not indicative of the underlying performance of its business, primarily relate to costs associated with rationalizing the company’s channel partners or vendors, transforming the company’s information systems infrastructure, integrating the company’s product roadmap, and accelerated depreciation on assets. Convertible debt activity, net. The company excludes non-cash economic interest expense associated with its convertible notes, the gains and losses on the conversion of its convertible senior notes and call option, and unrealized gains and losses related to the change in fair value of the exercise option and call option. These charges and gains and losses do not reflect the company’s operating results, and the company believes are not indicative of the underlying performance of its business. Debt extinguishment costs. From time-to-time, the company replaces its existing debt with new financing at more favorable interest rates or utilizes available capital to settle debt early, both of which generate interest savings in future periods. The company incurs debt extinguishment charges consisting of the costs to call the existing debt and/or the write-off of any related unamortized debt issuance costs. These gains and losses do not reflect the company’s operating results, and the company believes are not indicative of the underlying performance of its business. Other charges. From time-to-time, the company sells or impairs investments or other assets which are not considered necessary to its business operations, or incurs other charges or gains that the company believes are not a part of the ongoing operation of its business. The resulting expense or benefit is inconsistent in amount and frequency. Income tax adjustments. Income tax adjustments include the difference between income taxes based on a forecasted annual non- GAAP tax rate and a forecasted annual GAAP tax rate as a result of the timing of certain non-GAAP pre-tax adjustments. Additionally, as a result of the Tax Cuts and Jobs Act, the twelve months ended June 29, 2018 income tax adjustments include a provisional income tax expense of $1.6 billion for the one-time mandatory deemed repatriation tax and a provisional income tax benefit of $65 million related to the re-measurement of deferred tax assets and liabilities. Corporate Information BOARD OF DIRECTORS EXECUTIVE OFFICERS Stephen D.
