PART I

ITEM 1. BUSINESS

We are a leading provider of data storage technology and solutions. Our principal products are hard disk drives, commonly referred to as disk drives, hard drives or HDDs. In addition to HDDs, we produce a broad range of data storage products including solid state drives (“SSDs”), solid state hybrid drives (“SSHDs”) and storage subsystems.

Hard disk drives are devices that store digitally encoded data on rapidly rotating disks with magnetic surfaces. Disk drives continue to be the primary medium of mass data storage due to their performance attributes, high quality and cost effectiveness. Complementing existing data center storage architecture, solid-state storage devices use integrated circuit assemblies as memory to store data, and most SSDs use NAND flash memory. In addition to HDDs and SSDs, SSHDs combine the features of SSDs and HDDs in the same unit, containing a high capacity hard disk drive and a smaller SSD acting as a cache to improve performance of frequently accessed data.

Our HDD products are designed for mission critical and nearline applications in enterprise servers and storage systems; edge compute/client compute applications, where our products are designed primarily for desktop and mobile computing; and edge non-compute/client non-compute applications, where our products are designed for a wide variety of end user devices such as portable external storage systems, surveillance systems, digital video recorders (“DVRs”), network-attached storage (“NAS”) and gaming consoles. Our SSD products mainly include serial attached SCSI (“SAS”) and Non-Volatile Memory Express (“NVMe”) SSDs.

Our cloud systems and solutions portfolio includes modular original equipment manufacturer (“OEM”) storage systems and scale-out storage servers.

Industry Overview

Data Storage Industry

The data storage industry is comprised of companies that manufacture components or subcomponents designed for data storage devices and companies that provide storage solutions, software and services for enterprise cloud, big data, computing platforms and consumer markets. We believe the proliferation and personal creation of media-rich digital content will continue to create increasing consumer demand for higher capacity storage solutions.

Markets

The principal markets served by us include:

Enterprise Storage. We define enterprise storage as dedicated storage area networks and hyperscale cloud storage environments. Enterprise and cloud data centers run solutions which are designed for mission critical, nearline and enterprise serial attached SCSI SSDs applications.

Mission critical applications are defined as those that are vital to the operation of large-scale enterprise workloads, requiring high performance and high reliability storage solutions. We expect the market for mission critical enterprise storage solutions to continue to be driven by enterprises utilizing dedicated storage area networks. Our storage solutions are comprised principally of high performance enterprise class disk drives with sophisticated firmware and communications technologies.

Nearline applications are defined as those which require high capacity and energy efficient storage solutions. We expect such applications, which include storage for cloud computing, content delivery and backup services, will continue to grow and drive demand for solutions designed with these attributes. With the increased requirements for storage capacity and performance driven by the creation and consumption of media-rich digital content, we expect the increased exabyte demand will require further build-out of data centers by cloud service providers (“CSPs”) and other enterprises which utilize high capacity nearline devices.

Enterprise SAS SSDs are designed to deliver superior performance, reliability and enterprise features to meet the demands of I/O-intensive applications, with potential for substantial power savings. NVMe SSDs and add-in cards are designed to optimize enterprise applications with a persistent, high-performance, high-capacity memory design. They also leverage flash and software to accelerate any server virtualized deployment and move any big data to the realm of real time.

Seagate Technology public limited company | 2018 Form 10-K | 3

Edge Compute/Client Compute. We define edge compute/client compute applications as solutions designed for desktop and mobile compute applications ranging from traditional laptops to convertible systems. As storage of digital content in the cloud becomes more prevalent, accessible and affordable, some edge compute/client compute applications rely less on built-in storage, and instead have transitioned to cloud storage and computing solutions along with branded external hard drives.

Edge Non-Compute/Client Non-Compute. We define edge non-compute/client non-compute applications as solutions designed for consumer electronic devices and disk drives used for external storage. Disk drives designed for consumer electronic devices are primarily used in applications such as surveillance systems, DVRs, NAS and gaming consoles that require a higher capacity, low cost-per-gigabyte storage solution. Disk drives for external storage are designed for purposes such as portable external storage, and to augment storage capacity in the consumer’s current desktop, notebook, tablet or mobile phone devices.

Cloud Systems and Solutions. We define cloud systems and solutions as applications that provide solutions to businesses for the purpose of modular systems and scale-out storage solutions. Systems can contain HDDs and SSDs and may offer file management systems, software and compute power.

Participants in the data storage industry include:

Major subcomponent manufacturers. Companies that manufacture components or subcomponents used in data storage devices or solutions include companies that supply spindle motors, heads and media and application specific integrated circuits (“ASICs”).

Storage solutions manufacturers. Companies that transform components into storage products include disk drive manufacturers and semiconductor storage manufacturers which integrate flash memory into storage products such as SSDs.

System integrators. Companies, such as OEMs, that bundle and package storage solutions, distributors that integrate storage hardware and software into end-user applications and CSPs that provide cloud based solutions to businesses for the purpose of scale-out storage solutions and modular systems.

Hyperscale Data Centers. Large hyperscale data center companies which are increasingly designing their own storage subsystems and having them built by contract manufacturers for use inside their own data centers. This trend is reshaping the storage system and subsystem market and driving innovation in system design and changes in the competitive landscape of large storage system vendors.

Storage services. Companies that provide and host services and solutions, which include storage, backup, archiving, recovery and discovery of data.

Demand for Data Storage

The International Data Corporation (“IDC”) forecasted in its 2017 Data Age 2025 study that the global datasphere will grow to 163 zettabytes by 2025. According to IDC, we are fast approaching a new era of the data age, which we expect will have a positive impact on storage demand. We believe that the continued advancement of the cloud, the further development of edge computing, the global proliferation of mobile devices, the evolution of the Internet of Things (“IoT”), the increasing use of video surveillance, the evolution of consumer electronic devices, and the enterprise use of big data analytics are driving the growth of digital content. Factors contributing to the growth of digital content include:

• Creation, sharing, and consumption of media-rich digital content, such as high-resolution photos, high definition videos, and digital music through smart phones, tablets, digital cameras, personal video cameras, DVRs, gaming consoles or other digital devices;

• Creation, aggregation and distribution of digital content through services and other offerings such as Facebook^®, Instagram^®, iTunes^®, Netflix^®, Google^® and YouTube^®;

• Increasing use of video surveillance and the emergence of new surveillance systems which feature higher resolution digital cameras and thus require larger data storage capacities;

Seagate Technology public limited company | 2018 Form 10-K | 4

• Creation and collection of data through the development and evolution of the IoT ecosystem, big data analytics (including enterprise use of big data analytics) and new technology trends such as self-driving cars and drones;

• Continued advancement of the cloud, including the build out of large numbers of cloud data centers by CSPs and private companies transitioning on-site data centers into the cloud; and

• Protection of increased digital content through redundant storage on backup devices and externally provided storage services.

As a result of these factors, we anticipate that the nature and volume of content being created will require greater storage, which is more efficiently and economically facilitated by higher capacity storage devices in order to store, manage, distribute, analyze and backup such content. We expect this to support the growth in demand for data storage solutions in developed and emerging economies.

In addition, the economics of storage infrastructure are also evolving with the utilization of public and private hyper-scale storage and open-source solutions reducing the total cost of ownership of storage while increasing the speed and efficiency with which customers can leverage massive computing and storage devices. Accordingly, we expect these trends will continue to create significant demand for data storage solutions going forward.

Demand Trends

We believe that continued growth in digital content requires increasingly higher storage capacity in order to store, aggregate, host, distribute, analyze, manage, protect, backup and use such content. We also believe that as architectures evolve to serve the growing commercial and consumer user base throughout the world, the storage solutions will evolve as well.

We expect increased data creation will lead to the expansion of the need for storage in the form of both HDDs and SSDs. While the advance of solid state technology in many end markets is expected to increase, we believe that in the foreseeable future, cloud, traditional enterprise, client and consumer markets that require high-capacity storage solutions will be best served by hard disk drives due to their ability to deliver the most cost effective, reliable and energy efficient mass storage devices. We also believe that as hard disk drive capacities continue to increase, a focus exclusively on unit demand does not reflect the increase in demand for exabytes. This has resulted in demand for fewer units, but with higher average capacity per drive.

Industry Supply Balance

From time to time, the storage industry has experienced periods of imbalance between supply and demand. To the extent that the storage industry builds or maintains capacity based on expectations of demand that do not materialize, price erosion may become more pronounced. Conversely, during periods where demand exceeds supply, price erosion is generally muted.

Our Business

Disk Drive Technology

The design and manufacturing of disk drives depends on highly advanced technology and manufacturing techniques and therefore requires high levels of research and development spending and capital equipment investments. We design, fabricate and assemble a number of the most important components in our disk drives, including read/write heads and recording media. Our design and manufacturing operations are based on technology platforms that are used to produce various disk drive products that serve multiple data storage applications and markets. Our core technology platforms are focused around the areal density of media and read/write head technologies. This design and manufacturing approach allows us to deliver a portfolio of disk drive products to service a wide range of data storage applications and industries.

Disk drives that we manufacture are commonly differentiated by the following key characteristics:

• storage capacity, commonly expressed in gigabytes (“GB”) or terabytes (“TB”), which is the amount of data that can be stored on the disk drive;

• spindle rotation speed, commonly expressed in revolutions per minute (“RPM”), which has an effect on speed of access to data;

Seagate Technology public limited company | 2018 Form 10-K | 5

• interface transfer rate, commonly expressed in megabytes per second, which is the rate at which data moves between the disk drive and the computer controller;

• average seek time, commonly expressed in milliseconds, which is the time needed to position the heads over a selected track on the disk surface;

• data transfer rate, commonly expressed in megabytes per second, which is the rate at which data is transferred to and from the disk drive;

• input/output operations per second (“IOPS”), commonly expressed in megabytes per second, which is the maximum number of reads and writes to a storage location;

• product quality and reliability, commonly expressed in annualized return rates; and

• energy efficiency, commonly measured by the power output necessary to operate the disk drive.

Areal density is measured by storage capacity per square inch on the recording surface of a disk. The storage capacity of a disk drive is determined by the number of disks it contains as well as the areal density capability of these disks. We have been pursuing, and will continue to pursue, a number of technologies to increase areal densities across the entire range of our products for expanding disk drive capacities and reducing the number of disks and heads per drive to further reduce product costs.

Manufacturing

We design and produce our own read/write heads and recording media, which are critical technologies for disk drives. This integrated approach enables us to lower costs and to improve the functionality of components so that they work together efficiently.

We believe that because of our vertical design and manufacturing strategy, we are well suited to take advantage of the opportunities to leverage the close interdependence of components for disk drives. Our manufacturing efficiency and flexibility are critical elements of our integrated business strategy. We continuously seek to improve our manufacturing efficiency and reduce manufacturing costs by:

• employing manufacturing automation;

• utilizing machine learning algorithms and artificial intelligence;

• improving product quality and reliability;

• integrating our supply chain with suppliers and customers to enhance our demand visibility and reduce our working capital requirements;

• coordinating between our manufacturing group and our research and development organization to rapidly achieve volume manufacturing; and

• operating our facilities at optimal capabilities.

A vertically integrated model, however, tends to have less flexibility when demand moderates as it exposes us to higher unit costs when capacity utilization is not optimized.

Components and Raw Materials

Disk drives incorporate certain components, including a head disk assembly and a printed circuit board mounted to the head disk assembly, which are sealed inside a rigid base and top cover containing the recording components in a contamination controlled environment. We maintain a highly integrated approach to our business by designing and manufacturing a significant portion of the components we view as critical to our products, such as read/write heads and recording media.

Read/Write Heads. The function of the read/write head is to scan across the disk as it spins, magnetically recording or reading information. The tolerances of read/write heads are extremely demanding and require state-of-the-art equipment and

Seagate Technology public limited company | 2018 Form 10-K | 6

processes. Our read/write heads are manufactured with thin-film and photolithographic processes similar to those used to produce semiconductor integrated circuits, though challenges related to magnetic film properties and topographical structures are unique to the disk drive industry. We perform all primary stages of design and manufacture of read/write heads at our facilities. We use a combination of internally manufactured and externally sourced read/write heads, the mix of which varies based on product mix, technology and our internal capacity levels.

Media. Data is written to or read from the media, or disk, as it rotates at very high speeds past the read/write head. The media is made from non-magnetic substrates, usually an aluminum alloy or glass, and is coated with thin layers of magnetic materials. We use a combination of internally manufactured and externally sourced finished media and aluminum substrates, the mix of which varies based on product mix, technology and our internal capacity levels. We purchase all of our glass substrates from third parties.

Printed Circuit Board Assemblies. The printed circuit board assemblies (“PCBAs”) are comprised of standard and custom ASICs and ancillary electronic control chips. The ASICs control the movement of data to and from the read/write heads and through the internal controller and interface, which communicates with the host computer. The ASICs and control chips form electronic circuitry that delivers instructions to a head positioning mechanism called an actuator to guide the heads to the selected track of a disk where the data is recorded or retrieved. Disk drive manufacturers use one or more industry standard interfaces such as serial advanced technology architecture (“SATA”); small computer system interface (“SCSI”); SAS; or fiber channel to communicate to the host systems. We outsource to third parties the manufacture and assembly of the PCBAs used in our disk drives. We do not manufacture any ASICs, but we participate in their design.

Head Disk Assembly. The head disk assembly consists of one or more disks attached to a spindle assembly powered by a spindle motor that rotates the disks at a high constant speed around a hub. Read/write heads, mounted on an arm assembly, similar in concept to that of a record player, fly extremely close to each disk surface and record data on and retrieve it from concentric tracks in the magnetic layers of the rotating disks. The read/write heads are mounted vertically on an E-shaped assembly (“E-block”) that is actuated by a voice-coil motor to allow the heads to move from track to track. The E-block and the recording media are mounted inside the head disk assembly. We purchase spindle motors from outside vendors and from time to time participate in the design of the motors that go into our products.

Disk Drive Assembly. Following the completion of the head disk assembly, it is mated to the PCBA, and the completed unit goes through extensive defect mapping and machine learning prior to packaging and shipment. Disk drive assembly and machine learning operations occur primarily at our facilities located in China and Thailand. We perform subassembly and component manufacturing operations at our facilities in China, Malaysia, Northern Ireland, Singapore, Thailand and the United States. In addition, third parties manufacture and assemble components for us in various countries worldwide.

Suppliers of Components and Industry Constraints. There are a limited number of independent suppliers of components, such as recording heads and media, available to disk drive manufacturers. Vertically integrated disk drive manufacturers, who manufacture their own components, are less dependent on external component suppliers than less vertically integrated disk drive manufacturers. However, our business has been adversely affected by our suppliers’ capacity constraints in the past and this could occur again.

Commodity and Other Manufacturing Costs. The production of disk drives requires rare earth elements, precious metals, scarce alloys and industrial commodities, which are subject to fluctuations in price and the supply of which has at times been constrained. In addition to increased costs of components and commodities, volatility in fuel costs may also increase our costs related to commodities, manufacturing and freight. As a result, we may increase our use of alternative shipment methods to help offset any increase in freight costs, and will continually review various forms of shipments and routes in order to minimize the exposure to higher freight costs.

Anticipated orders from many of our customers have in the past failed to materialize or OEM delivery schedules have been deferred or altered as a result of changes in their business needs.

Our distributors generally enter into non-exclusive agreements for the resale of our products. They typically furnish us with a non-binding indication of their near-term requirements and product deliveries are generally scheduled accordingly. The agreements and related sales programs typically provide the distributors with limited rights of return and price protection rights. In addition, we offer sales programs to distributors on a quarterly and periodic basis to promote the sale of selected products in the sales channel.

Our retail channel consists of our branded storage products sold to retailers either by us directly or by our distributors. Retail sales made by us or our distributors typically require greater marketing support, sales incentives and price protection periods.

In fiscal year 2018, no customer accounted for more than 10% of consolidated revenue. In fiscal years 2017 and 2016, Dell Inc. accounted for approximately 10% and 12% of consolidated revenue, respectively. See “Item 1A. Risk Factors-Risks Related to Our Business-We may be adversely affected by the loss of, or reduced, delayed or canceled purchases by, one or more of our key customers.”

Competition

We compete primarily with manufacturers of hard drives used in the enterprise, edge compute/client compute and edge non-compute/client non-compute applications and with other companies in the data storage industry that provide SSDs and NVMe add-in technology. Some of the principal factors used by customers to differentiate among data storage solutions manufacturers are storage capacity, product performance, product quality and reliability, price per unit and price per gigabyte, storage/retrieval access times, data transfer rates, form factor, product warranty and support capabilities, supply continuity and flexibility, power consumption, total cost of ownership, and brand. While different markets and customers place varying levels of emphasis on these factors, we believe that our products are competitive with respect to many of these factors in the markets that we currently address.

Principal Competitors. We compete with manufacturers of storage solutions and the principal manufactures in the data storage solution industry include:

• Seagate, selling the Seagate, LaCie and Maxtor brands;

• Micron Technology, Inc.;

Seagate Technology public limited company | 2018 Form 10-K | 9

• Samsung Electronics;

• SK Hynix, Inc.;

• Toshiba Corporation; and

• Western Digital Corporation, operating the Western Digital and Hitachi Global Storage Technologies subsidiaries and SanDisk.

Price Erosion. Historically, our industry has been characterized by price declines for disk drive products with comparable capacity, performance and feature sets (“like-for-like products”). Price declines for like-for-like products (“price erosion”) tend to be more pronounced during periods of:

• economic contraction in which competitors may use discounted pricing to attempt to maintain or gain market share;

• few new product introductions when competitors have comparable or alternative product offerings; and

• industry supply exceeding demand.

Disk drive manufacturers typically attempt to offset price erosion with an improved mix of disk drive products characterized by higher capacity, better performance and additional feature sets and product cost reductions.

We believe the HDD industry experienced modest price erosion in fiscal years 2016, 2017 and 2018.

Product Life Cycles and Changing Technology. Success in our industry has been dependent to a large extent on the ability to balance the introduction and transition of new products with time-to-volume, performance, capacity and quality metrics at a competitive price, level of service and support that our customers expect. Generally, the drive manufacturer that introduces a new product first benefits from improved product mix, favorable profit margins and less pricing pressure until comparable products are introduced. Changing technology also necessitates on-going investments in research and development, which may be difficult to recover due to rapid product life cycles and economic declines. Further, there is a continued need to successfully execute product transitions and new product introductions, as factors such as quality, reliability and manufacturing yields continue to be of significant competitive importance.

Seasonality

The disk drive industry traditionally experiences seasonal variability in demand with higher levels of demand in the second half of the calendar year. This seasonality is driven by consumer spending in the back-to-school season from late summer to fall and the traditional holiday shopping season from fall to winter. Beyond traditional seasonality, variability of sales can be related to IT spending or a reflection of more cyclical demand from CSPs based on the timing of procurement, deployment and market supply and demand balance of other components such as NAND and DRAM.

Research and Development

We are committed to developing new component technologies, products and alternative storage technologies. Our research and development focus is designed to bring new products to market in high volume, with quality attributes that our customers expect, before our competitors. Part of our product development strategy is to leverage a design platform and/or subsystem within product families to serve different market needs. This platform strategy allows for more efficient resource utilization, leverages best design practices, reduces exposure to changes in demand, and allows for achievement of lower costs through purchasing economies. Our advanced technology integration effort focuses disk drive and component research on recording subsystems, including read/write heads and recording media; market-specific product technology; and technology focused towards new business opportunities. The primary purpose of our advanced technology integration effort is to ensure timely availability of mature component technologies for our product development teams as well as to allow us to leverage and coordinate those technologies in the design centers across our products in order to take advantage of opportunities in the marketplace. During fiscal years 2018, 2017 and 2016, we had product development expenses of approximately $1,026 million, $1,232 million and $1,237 million, respectively, which represented 9%, 11% and 11% of our consolidated revenue, respectively.

Seagate Technology public limited company | 2018 Form 10-K | 10

Patents and Licenses

As of June 29, 2018, we had approximately 6,000 U.S. patents and 1,400 patents issued in various foreign jurisdictions as well as approximately 1,000 U.S. and 600 foreign patent applications pending. The number of patents and patent applications will vary at any given time as part of our ongoing patent portfolio management activity. Due to the rapid technological change that characterizes the data storage industry, we believe that, in addition to patent protection, the improvement of existing products, reliance upon trade secrets, protection of unpatented proprietary know-how and development of new products are also important to our business in establishing and maintaining a competitive advantage. Accordingly, we intend to continue our efforts to broadly protect our intellectual property, including obtaining patents, where available, in connection with our research and development program.

The data storage industry is characterized by significant litigation arising from time to time relating to patent and other intellectual property rights. From time to time, we receive claims that our products infringe patents of third parties. Although we have been able to resolve some of those claims or potential claims without a material adverse effect on us, other claims have resulted in adverse decisions or settlements. In addition, other claims are pending, which if resolved unfavorably to us could have a material adverse effect on our business and results of operations. For more information on these claims, see “Item 8. Financial Statements and Supplementary Data—Note 14. Legal, Environmental and Other Contingencies.” The costs of engaging in intellectual property litigation in the past have been, and in the future may be, substantial, irrespective of the merits of the claim or the outcome.

Backlog

In view of industry practice, whereby customers may cancel or defer orders with little or no penalty, we believe backlog for our business is of limited indicative value in estimating future performance and results.

Environmental Matters

Our operations are subject to U.S. and foreign laws and regulations 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 wastes and the cleanup of contaminated sites. Some of our operations require environmental permits and controls to prevent and reduce air and water pollution, and these permits are subject to modification, renewal and revocation by issuing authorities.

We have established environmental management systems and continually update 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. If additional or more stringent requirements are imposed on us in the future, we could incur additional operating costs and capital expenditures.

Some environmental laws, such as the Comprehensive Environmental Response Compensation and Liability Act of 1980 (as amended, the “Superfund” law) and its state equivalents, can impose liability for the cost of cleanup of contaminated sites upon any of the current or former site owners or operators or upon parties who sent waste to these sites, regardless of whether the owner or operator owned the site at the time of the release of hazardous substances or the lawfulness of the original disposal activity. We have been identified as a responsible or potentially responsible party at several sites. At each of these sites, we have an assigned portion of the financial liability based on the type and amount of hazardous substances disposed of by each party at the site and the number of financially viable parties. We have fulfilled our responsibilities at some of these sites and remain involved in only a few at this time.

While our ultimate costs in connection with these sites are difficult to predict, based on current estimates of cleanup costs and our expected allocation of these costs, we do not expect costs in connection with these sites to be material.

We may be subject to various state, federal and international laws and regulations governing environmental matters, including those restricting the presence of certain substances in electronic products. For example, the European Union (“EU”) has enacted the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment, which prohibits the use of certain substances, including lead, in certain products, including disk drives and server storage products,

Seagate Technology public limited company | 2018 Form 10-K | 11

put on the market after July 1, 2006. Similar legislation has been or may be enacted in other jurisdictions, including in the United States, Canada, Mexico, Taiwan, China, Japan and others. The European Union REACH Directive (Registration, Evaluation, Authorization, and Restriction of Chemicals, EC 1907/2006) also restricts substances of very high concern (“SVHCs”) in products.

Employees

At June 29, 2018, we employed approximately 43,000 employees and temporary employees worldwide, of which approximately 36,000 were located in our Asian operations. We believe that our future success will depend in part on our ability to attract and retain qualified employees at all levels. We believe that our employee relations are good.

ITEM 1A. RISK FACTORS

Our industry is highly competitive and our failure to anticipate and respond to technological and market developments could harm our ability to compete.

We operate in markets that are highly competitive and subject to rapid change, and that are significantly affected by new product introductions and technological advancements. Our competitors also may aggressively lower prices as part of a strategy to gain or retain market share and customers. If these practices continue, we may need to continually reduce our prices for existing products to retain our market share, which could adversely affect our results of operations.

Our ability to offset the effect of price erosion through new product introductions at higher average prices may be diminished to the extent competitors introduce products before we introduce similar, competing products. We may also lose market share if we are unable to ramp volume production of new products as quickly as our competitors ramp production of similar competing products. Any significant decline in our market share in any of our principal market applications would adversely affect our results of operations.

Our principal sources of competition include:

• disk drive and solid state drive (“SSD”) manufacturers, such as Micron Technology, Inc., Samsung Electronics, SK Hynix, Inc., Toshiba Corporation and Western Digital Corporation;

• companies providing storage subsystems and components to OEMs;

• electronic manufacturing services (“EMS”) companies acquiring the necessary skills and intellectual property to enter the enterprise data storage marketplace; and

• collaborations between in-house development teams of existing and potential customers and a combination of EMS, contract electronic manufacturing (“CEM”) or emerging technology companies.

We also experience competition from other companies that produce alternative storage technologies such as flash memory, where increasing capacity, decreasing cost, energy efficiency and improvements in performance ruggedness have resulted in competition with our lower capacity, smaller form factor disk drives. This competition has traditionally been in the markets for handheld consumer electronics applications and now it also includes SSDs for tablet, notebook and enterprise compute applications. Some customers for both enterprise and edge compute applications are adopting SSDs as alternatives to hard drives in certain applications. Further adoption of these alternative storage technologies may impact the competitiveness of our product portfolio and reduce our market share and adversely affect our results of operations.

The markets for our data storage system products are also characterized by technological change, which is driven in part by the adoption of new industry standards. These standards provide mechanisms to ensure technology component interoperability can occur and may reduce our capability for differentiation or innovation. If this occurs, our affected products may be considered commodities. This could lower the barriers for entry to our market away from our specialized research and development skills and enable entry for the general-purpose design skills found in some large EMS and CEM companies. Commodity markets are driven by extremely low margins and very aggressive competitive pricing. If our market becomes more commoditized and we fail to deliver innovative value-added alternatives to our customers or if our component manufacturers transfer their business to our competitors, we will have difficulty competing against the larger EMS and CEM companies which could reduce our profit margin or result in a loss of market share, which could significantly harm our financial condition.

We may be unable to effectively plan and make strategic changes in our business which may materially adversely affect our financial and business results. Additionally, even if we are able to make desired strategic changes, we may not achieve the intended benefits of our efforts.

If we fail to predict demand accurately for our products in any quarter or if the market for our products changes, we may not be able to recapture the cost of our investments, which may materially adversely affect our financial results and results of operations.

Our industry operates primarily on quarterly purchasing cycles, with much of the order flow in any given quarter typically coming at the end of that quarter. Our quarterly results are subject to substantial fluctuations and can be difficult to predict. Our

Seagate Technology public limited company | 2018 Form 10-K | 14

manufacturing process requires us to make significant product-specific investments in inventory in each quarter for production in that quarter and future quarters. Since we typically receive the bulk of our orders late in a quarter after we have made our investments, there is a risk that our orders will not be sufficient to allow us to recapture the costs of our investment before the products resulting from that investment have become obsolete. We cannot provide any assurance that we will be able to accurately predict demand in the future.

Our revenues in any quarter are substantially dependent upon customer orders in that quarter. We attempt to project future orders based, in part, on estimates from our key customers. Our customers’ estimated requirements are not always accurate and, therefore, we cannot predict our quarterly revenues with any degree of certainty. In addition, we derive a portion of our revenues in each quarter from a number of relatively large orders. If one or more of our key customers decides to defer a purchase order or delays product acceptance in any given quarter, our revenues for that quarter may be significantly reduced and fall below our expectations.

The difficulty in forecasting demand also increases the difficulty in anticipating our inventory requirements, which may cause us to overproduce or underproduce finished goods. If we do not produce enough finished goods to meet customer requirements, we may be unable to maintain our market share. Additionally, the risk of obsolescence or lower of cost and net realizable value inventory write-offs could increase if we were to carry excess inventory levels for extended periods or due to volatility in the pricing environment. Our uneven sales cycle makes inventory management challenging and future financial results less predictable. We cannot be certain that we will be able to recover the costs associated with increased inventory.

Other factors that may adversely affect our ability to recapture the cost of investments in any given quarter include:

• the impact of variable demand and an aggressive pricing environment for disk drives or SSDs;

• the impact of competitive product announcements and possible excess industry supply both with respect to particular disk drive products and with respect to competing alternative storage technology solutions, such as SSDs, in tablet, notebook and enterprise compute applications;

• our inability to reduce our fixed costs to match sales in any quarter because of our vertical manufacturing strategy;

• dependence on our ability to successfully qualify, manufacture and sell our disk drive products, particularly new disk drive products, in increasing volumes, on a cost-effective basis, and with acceptable quality;

• uncertainty in the amount of purchases from our key customers who from time to time constitute a large portion of our total sales;

• our product mix and the related gross margins of our products;

• accelerated reduction in the price of our disk drives due to technological advances and/or an oversupply of disk drives in the market and shifting trends in demand which can create supply and demand imbalances;

• manufacturing delays or interruptions, particularly at our manufacturing facilities in China, Malaysia, Northern Ireland, Singapore, Thailand, or the United States;

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

• the impact of changes in foreign currency exchange rates on the cost of producing our products and the effective price of our products to foreign consumers; and

• operational issues arising out of the increasingly automated nature of our manufacturing processes.

In addition, the demand for edge non-compute/client non-compute products can be even more volatile and unpredictable than the demand for edge compute/client compute products. In some cases, our products manufactured for edge non-compute/client non-compute applications are uniquely configured for a single customer’s application, which creates a risk of unwanted and unsellable inventory if the anticipated volumes are not realized. This potential for unpredictable volatility is increased by the possibility of competing alternative storage technologies, such as flash memory, meeting the customers’ cost and capacity metrics, resulting in a rapid shift in demand from our products and disk drive technology, generally, to alternative storage technologies. Unpredictable fluctuations in demand for our products or rapid shifts in demand from our products to alternative storage technologies in new edge non-compute/client non-compute applications could materially adversely impact

Seagate Technology public limited company | 2018 Form 10-K | 15

our future results of operations. Additionally, we are dependent on our long-term investment to manufacture adequate products. Our investment decisions in adding a new assembly and test capacity require significant planning and lead-time, and a failure to accurately forecast demand for our products could cause us to over-invest or under-invest, which would lead to excess capacity, under-utilization charges, impairments or loss of sales and revenue opportunities.

Market acceptance of new product introductions cannot be accurately predicted, and our results of operations will suffer if there is less demand for our new products than is anticipated.

The markets for our products are characterized by rapid technological change, frequent new product introductions and technology enhancements, uncertain product life cycles and changes in customer demand. The success of our new product introductions is dependent on a number of factors, including market acceptance, our ability to manage the risks associated with product transitions, our ability to effectively manage inventory levels in line with anticipated product demand and the risk that our new products will have quality problems or other defects in the early stages of introduction that were not anticipated in the design of those products. Accordingly, we cannot accurately determine the ultimate effect that our new products will have on our results of operations. Our failure to accurately anticipate customers’ needs and accurately identify the shift in technological changes could materially adversely affect our long-term financial results.

Historically, our results of operations have substantially depended upon our ability to be among the first-to-market with new disk drive product offerings. We may face technological, operational and financial challenges in developing new products. In addition, our investments in new product development may not yield the anticipated benefits. Our market share and results of operations in the future may be adversely affected if we fail to:

• consistently maintain our time-to-market performance with our new products;

• produce these products in adequate volume;

• qualify these products with key customers on a timely basis by meeting our customers’ performance and quality specifications; or

• achieve acceptable manufacturing yields, quality and costs with these products.

In addition, the success of our new product introductions is dependent upon our ability to qualify as a primary source of supply with our OEM customers. In order for our products to be considered by our customers for qualification, we must be among the leaders in time-to-market with those new products. Once a product is accepted, any failure or delay in the qualification process or a requirement that we requalify can result in our losing sales to that customer until new products are introduced. The limited number of high-volume OEMs magnifies the potential effect of missing a product qualification opportunity. These risks are further magnified because we expect competitive pressures to result in declining sales, eroding prices and declining gross margins on our current generation products. If the delivery of our products is delayed, our OEM customers may use our competitors’ products to meet their production requirements. We cannot assure you that we will be among the leaders in time-to-market with new products or that we will be able to successfully qualify new products with our customers in the future.

We face the related risk that consumers and businesses may wait to make their purchases to evaluate new products or if they want to buy a new product that has been announced but not yet released. If this were to occur, we may be unable to sell our existing inventory of products that may be less efficient and cost effective compared to new products. As a result, even if we are among the first-to-market with a given product, subsequent introductions or announcements by our competitors of new products could cause us to lose revenue and not achieve a positive return on our investment in existing products and inventory.

If we cannot successfully deliver competitive products, our future results of operations may be adversely affected. Further, due to market competition, volatility, and rapid technology and price changes, we may be unable to accurately forecast demand resulting in insufficient or excess production or purchase of products or components inventory, any of which could have a material adverse effect on our business and financial results.

We may not be able to identify suitable strategic alliances, acquisitions, joint ventures or investment opportunities to successfully acquire and integrate companies that provide complementary products or technologies or to realize the anticipated benefits of such transactions.

Our long-term growth strategy involves pursuing strategic alliances with, making acquisitions of, forming joint ventures with or making investments in other companies that are complementary to our business. There is substantial competition for

Seagate Technology public limited company | 2018 Form 10-K | 16

attractive strategic alliance, acquisition, joint venture and investment candidates. Additionally, a trend of consolidation in the data storage industry could materially adversely affect our business and financial results and our future growth prospects. Accordingly, we may not be able to identify suitable strategic alliances, acquisition, joint venture, or investment candidates. Even if we can identify them, the terms on which we are able to consummate a transaction may not be commercially reasonable for us to pursue. We cannot assure you that we will be able to partner with, acquire or invest in suitable candidates, or integrate acquired technologies or operations successfully into our existing technologies and operations. Moreover, our ability to finance potential strategic alliances, acquisitions, joint ventures or investments may be limited by our leverage level, the covenants contained in the instruments that govern our outstanding indebtedness, and any agreements governing any other debt we may incur. In addition, our cash reserves could diminish significantly as a result of any acquisitions, joint ventures, strategic alliances or other investments we pursue.

Even if we are successful in forming strategic alliances or acquiring, forming joint ventures with or making investments in other companies, these transactions may have an adverse effect on our results of operations, particularly while the operations of an acquired business are being integrated. It is also likely that integration of acquired companies would lead to the loss of key employees from those companies or the loss of customers of those companies. In addition, the integration of any acquired companies would require substantial attention from our senior management, which may limit the amount of time available to be devoted to our day-to-day operations or to the execution of our strategy. Growth by strategic alliance, acquisition, joint venture or investment involves an even higher degree of risk to the extent we combine new product offerings and enter new markets in which we have limited experience, and no assurance can be given that acquisitions of entities with new or alternative business models will be successfully integrated or achieve the desired objectives. There can be no assurance that we will realize the anticipated benefits or synergies of any strategic alliance, acquisition, joint venture or investment that we make or, if we do, how long it will take to achieve such benefits.

Furthermore, the expansion of our business involves the risk that we may not manage our growth effectively, that we would incur additional debt to finance these acquisitions or investments that would increase our debt service obligations, and that we may have impairment of goodwill or acquired intangible assets associated with these acquisitions and investments. Each of these items could have a material adverse effect on our financial condition and results of operations.

In addition, we could issue additional ordinary shares in connection with future strategic alliances, acquisitions, joint ventures or investments. Issuing shares in connection with such transactions would have the effect of diluting the ownership percentage of the outstanding ordinary shares and could cause the price of our ordinary shares to decline and impact our existing dividend policy or share repurchase program resulting in diminishing shareholders’ value.

If we do not develop products in time to keep pace with technological changes, our results of operations will be adversely affected.

Our customers demand new generations of storage products as advances in computer hardware and software have created the need for improved storage products, with features such as increased storage capacity, enhanced security, improved performance and reliability and lower cost. We, and our competitors, have developed improved products, and we will need to continue to do so in the future. Such product development requires significant investments in research and development. We cannot assure you that we will be able to successfully complete the design or introduction of new products in a timely manner, that we will be able to manufacture new products in sufficient volumes with acceptable manufacturing yields, that we will be able to successfully market these new products or that these products will perform to specifications on a long-term basis. In addition, the impact of slowing areal density growth may adversely impact our ability to be successful.

When we develop new products with higher capacity and more advanced technology, our results of operations may decline because the increased difficulty and complexity associated with producing these products increases the likelihood of reliability, quality or operability problems. If our products experience increases in failures rates, are of low quality or are not reliable, customers may reduce their purchases of our products, our factory utilization may decrease and our manufacturing rework and scrap costs and our service and warranty costs may increase. In addition, a decline in the reliability of our products may make us less competitive.

Additionally, we may be unable to produce new products that have higher capacities and more advanced technologies in the volumes and timeframes that are required to meet customer demand. We announced our future transition to key areal density recording technologies that will use heated-assisted magnetic reading (“HAMR”) technology to increase HDD

Seagate Technology public limited company | 2018 Form 10-K | 17

capacities. If our transitions to more advanced technologies, including the transition to HDDs utilizing HAMR technology, require development and production cycles that are longer than anticipated or if we otherwise fail to implement new HDD technologies successfully, we may lose sales and market share, which could significantly harm our financial condition.

We may fail to successfully anticipate technological shifts, business opportunities and market demand. We also may be subject to risks associated with entry into the NAND flash memory market. If we are unable to successfully to penetrate the NAND flash memory market, our future growth prospects may be materially adversely affected. We may fail to develop new products, identify business strategies and introduce competitive product offerings to meet those technological shifts which may materially adversely affect our ability to compete effectively and may impact our future financial results.

Servicing our indebtedness requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial debt.

We are leveraged and have significant debt service obligations. Our significant debt and debt service requirements could adversely affect our ability to operate our business and may limit our ability to take advantage of potential business opportunities and reduce our options for capital allocation. Our high level of debt presents the following risks:

• we are required to use a substantial portion of our cash flow from operations to pay principal and interest on our debt, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, product development efforts, strategic acquisitions, investments and alliances, and other general corporate requirements;

• our substantial leverage increases our vulnerability to economic downturns and adverse competitive and industry conditions and could place us at a competitive disadvantage compared to those of our competitors that are less leveraged;

• our debt service obligations could limit our flexibility in planning for, or reacting to, changes in our business and our industry and could limit our ability to pursue other business opportunities, borrow more money for operations or capital in the future and implement our business strategies;

• our level of debt may restrict us from raising additional financing on satisfactory terms to fund working capital, capital expenditures, product development efforts, strategic acquisitions, investments and alliances, and other general corporate requirements; and

• covenants in our debt instruments limit our ability to pay future dividends or make other restricted payments and investments.

Our business may not generate cash flow in an amount sufficient to enable us to pay the principal of, or interest on, our indebtedness. Further, in the event that we need to refinance all or a portion of our outstanding debt as it matures or incur additional debt to fund our operations, we may not be able to obtain terms as favorable as the terms of our existing debt or refinance our existing debt at all. If prevailing interest rates or other factors result in higher interest rates upon refinancing, then the interest expense relating to the refinanced debt would increase. Furthermore, if any rating agency changes our credit rating or outlook, our debt and equity securities could be negatively affected, which could adversely affect our ability to refinance existing debt or raise additional capital.

In addition, our business may not generate cash flow in an amount sufficient to enable us to fund our other liquidity needs, including working capital, capital expenditures, product development efforts, strategic acquisitions, investments and alliances and other general corporate requirements. If we cannot fund our liquidity needs, we will have to take actions such as reducing or delaying capital expenditures, product development efforts, strategic acquisitions, investments and alliances, and other general corporate requirements. We cannot assure you that any of these remedies could, if necessary, be effected on commercially reasonable terms, or at all, or that they would permit us to meet our scheduled debt service obligations. In addition, if we incur additional debt, the risks associated with our substantial leverage, including the risk that we will be unable to service our debt or generate enough cash flow to fund our liquidity needs, could intensify.

Changes in demand for computer systems and storage subsystems may in the future cause a decline in demand for our products.

Our products are components in computers, data storage systems, and consumer electronics devices. Historically, the demand for these products has been volatile. Unexpected slowdowns in demand for computer systems, storage subsystems

Seagate Technology public limited company | 2018 Form 10-K | 18

or consumer electronics devices generally cause sharp declines in demand for our products. Declines in consumer spending could have a material adverse effect on demand for our products and services and on our financial condition and results of operations.

While sales to edge non-compute/client non-compute and Cloud Systems and Solutions markets are becoming a more significant source of revenue, sales to the edge compute/client compute market remain an important part of our business. The edge compute/client compute market, however, has been, and we expect it to continue to be, adversely affected by the growth of tablet computers, smart phones and similar devices that perform many of the same capabilities as computers, the lengthening of product life cycles and macroeconomic conditions. We believe that the deterioration of the edge compute/client compute market has accelerated recently, and that this accelerated deterioration may continue or further accelerate, which could cause our operating results to suffer. Additionally, if demand in the edge compute/client compute market is worse than expected as a result of these or other conditions, demand for our products in the edge compute/client compute market may decrease at a faster rate and our operating results may be adversely affected.

The Enterprise Storage market for disk drives has been adversely affected by the growth of the utilization of NAND flash memory in mission critical applications. This deterioration of the Enterprise Storage disk drive market could cause our operating results to suffer. An acceleration of the pace of migration of the Enterprise Storage market to NAND flash memory products may materially adversely affect our financial results.

Historically, causes of declines in demand for our products have included weakness in macroeconomic environments, announcements or introductions of major new operating systems or semiconductor improvements or shifts in consumer preferences and behavior, such as the shift to mobile devices. We believe these announcements and introductions have from time to time caused consumers to defer their purchases and made inventory obsolete. Whenever an oversupply of products causes participants in our industry to have higher than anticipated inventory levels, we experience even more intense price competition from other manufacturers than usual, which may materially adversely affect our financial results.

Increases in the areal density of our disk drives may outpace our customers’ demand for storage capacity.

The rate of increase in areal density, or storage capacity per square inch on a disk, may be greater than the increase in our customers’ demand for aggregate storage capacity, particularly in certain market applications, such as edge compute/client compute. As a result, our customers’ storage capacity needs may be satisfied with lower priced, low capacity disk drives. These factors could decrease our sales, especially when combined with continued price erosion, which could adversely affect our results of operations.

We may not be successful in our efforts to grow our cloud systems and solutions revenues.

We have made and continue to make investments to grow our cloud systems and solutions revenues. Our ability to grow cloud systems and solutions revenues is subject to the following risks:

• our position in the cloud systems and solutions revenues may grow more slowly than we expect;

• we may be unable to accurately estimate and predict data center capacity and requirements;

• we may not be able to offer compelling solutions to enterprises and consumers;

• our cloud systems revenues generally have a longer sales cycle, and growth is likely to depend on relatively large customer orders, which may increase the variability of our results of operations and the difficulty of matching revenues with expenses; and

• we may not be able to maintain our historical overall growth margins as we grow our cloud systems and solutions revenues.

Our results of operations and share price may be adversely affected if we are not successful in our efforts to grow our revenues as anticipated. In addition, our growth in these markets may bring us into closer competition with some of our customers or potential customers, which may decrease their willingness to do business with us.

Seagate Technology public limited company | 2018 Form 10-K | 19

Changes in the macroeconomic environment may in the future negatively impact, our results of operations.

Changes in macroeconomic conditions may affect consumer and enterprise spending, and as a result, our customers may postpone spending in response to volatility in credit and equity markets, negative financial news and/or declines in income or asset values, all of which may have a material adverse effect on the demand for our products. Additionally, enterprise spending continues to remain cautious in many regions around the world. Other factors that could influence demand include conditions in the labor market, healthcare costs, access to credit, consumer confidence and other macroeconomic factors affecting consumer spending behavior. These and other economic factors could have a material adverse effect on demand for our products and on our financial condition and results of operations.

Macroeconomic developments such as the pending withdrawal of the United Kingdom from the European Union, the debt crisis in certain countries in the European Union, slowing economies in parts of Asia and South America or increased tariffs could negatively affect our business, operating results or financial condition which, in turn, could adversely affect the price of our ordinary shares. A general weakening of, and related declining corporate confidence in, the global economy or the curtailment in government or corporate spending could cause current or potential customers to reduce their IT budgets or be unable to fund hardware systems, which could cause customers to delay, decrease or cancel purchases of our products or cause customers not to pay us or to delay paying us for previously purchased products and services.

Our quarterly results of operations fluctuate, sometimes significantly, from period to period, and may cause our share price to decline.

Our quarterly revenue and results of operations may fluctuate, sometimes significantly, from period to period. These fluctuations, which we expect to continue, may be occasioned by a variety of factors, including:

• current uncertainty in global economic and political conditions which may pose a risk to the overall economy and adversely affect our customers’ purchasing behavior;

• adverse changes in the level of economic activity in the major regions in which we do business;

• competitive pressures resulting in lower selling prices by our competitors which may shift demand away from our products toward our competitors;

• delays or problems in our introduction of new, more cost-effective products, the inability to achieve high production yields or delays in customer qualification or initial product quality issues;

• changes in purchasing patterns by our distributor customers;

• application of new or revised industry standards;

• disruptions in our supply chain;

• increased costs or adverse changes in availability of supplies of raw materials or components;

• the impact of corporate restructuring activities that we have and may continue to engage in;

• changes in the demand for the computer systems and data storage products that contain our products due to seasonality, economic conditions and other factors;

• changes in purchases from period to period by our primary customers;

• shifting trends in customer demand which, when combined with overproduction of particular products, particularly when the industry is served by multiple suppliers, results in unfavorable supply and demand imbalances;

• our high proportion of fixed costs, including research and development expenses;

• any impairments in goodwill or other long-lived assets;

• announcements of new products, services or technological innovations by us or our competitors;

• changes in tax laws, regulatory requirements, including export regulations or tariffs, or accounting standards; and

• adverse changes in the performance of our products.

Seagate Technology public limited company | 2018 Form 10-K | 20

As a result, we believe that quarter-to-quarter and year-over-year comparisons of our revenue and results of operations may not be meaningful, and that these comparisons may not be an accurate indicator of our future performance. Our results of operations in one or more future quarters may fail to meet the expectations of investment research analysts or investors, which could cause an immediate and significant decline in our market value.

We experience seasonal declines in the sales of our products during the second half of our fiscal year which may adversely affect our results of operations.

Sales of computer systems, storage subsystems and consumer electronics tend to be seasonal, and therefore, we expect to continue to experience seasonality in our business as we respond to variations in our customers’ demand for our products. In particular, we anticipate that sales of our products will continue to be lower during the second half of our fiscal year. In the edge compute/client compute and edge non-compute/client non-compute market applications of our disk drive business, this seasonality is partially attributable to the historical trend in our results derived from our customers’ increased sales of desktop computers, notebook computers, and consumer electronics during the back-to-school and winter holiday season. In the enterprise storage market, our sales are seasonal because of the capital budgeting and purchasing cycles of our end users. Since our working capital needs peak during periods in which we are increasing production in anticipation of orders that have not yet been received, our results of operations will fluctuate seasonally even if the forecasted demand for our products proves accurate. Furthermore, it is difficult for us to evaluate the degree to which this seasonality may affect our business in future periods because of the rate and unpredictability of product transitions and new product introductions, particularly in the edge non-compute/client non-compute market, as well as macroeconomic conditions.

We have a long and unpredictable sales cycle for enterprise data storage solutions, which impairs our ability to accurately predict our financial and operating results in any periods and may adversely affect our ability to forecast the need for investments and expenditures.

Our enterprise data storage solutions are technically complex and we typically supply them in high quantities to a small number of customers. Many of our products are also tailored to meet the specific requirements of individual customers, and are often integrated by our customers into the systems and products that they sell. Factors that affect the length of our sales cycle include:

• the time required for developing, testing and evaluating our products before they are deployed;

• the size of the deployment; and

• the degree of system configuration necessary to deploy our products.

As a result, our sales cycle for enterprise data storage solutions is often in excess of one year and frequently unpredictable. Given the length of development and unpredictability of the sales cycle, we may be unable to accurately forecast product demand, which may result in lost sales or excess inventory and associated inventory reserves or write-downs, each of which could harm our business, financial condition and results of operations.

In addition, the emerging and evolving nature of the market for the products that we sell may lead prospective customers to postpone their purchasing decisions. We invest resources and incur costs during this cycle that may not be recovered if we do not successfully conclude sales. These factors lead to difficulty in matching revenues with expenses and increased expenditures and inventory, which together may adversely impact our results of operations.

We may be adversely affected by the loss of, or reduced, delayed or canceled purchases by, one or more of our key customers or a counterparty’s default.

Some of our key customers account for a large portion of our disk drive revenue. While we have long-standing relationships with many of our customers, if any of our key customers were to significantly reduce their purchases from us, our results of operations would be adversely affected. Although sales to key customers may vary from period to period, a key customer that permanently discontinues or significantly reduces its relationship with us could be difficult to replace. In line with industry practice, new customers usually require that we pass a lengthy and rigorous qualification process at the customer’s cost. Accordingly, it may be difficult or costly for us to attract new key customers. Additionally, mergers, acquisitions,

Seagate Technology public limited company | 2018 Form 10-K | 21

consolidations or other significant transactions involving our customers generally entail risks to our business. If a significant transaction involving any of our key customers results in the loss of or reduction in purchases by these key customers, it could have a materially adverse effect on our business, results of operations and financial condition.

If a counterparty fails to comply with their contractual obligations, our business, results of operations and financial condition may be adversely affected. Our ability to mitigate a counterparty’s default may be impeded or diminished by various factors including the terms of our contractual arrangements, market conditions, counterparty insolvency or bankruptcy, or applicable laws and regulations.

We are dependent on sales to distributors and retailers, which may increase price erosion and the volatility of our sales.

A substantial portion of our sales has been to distributors of disk drive products. Certain of our distributors may also market other products that compete with our products. Product qualification programs in this distribution channel are limited, which increases the number of competing products that are available to satisfy demand, particularly in times of lengthening product cycles. As a result, purchasing decisions in this channel are based largely on price, terms and product availability. Sales volumes through this channel are also less predictable and subject to greater volatility than sales to our OEM customers. In addition, deterioration in business and economic conditions could exacerbate price erosion and volatility as distributors lower prices to compensate for lower demand and higher inventory levels. Our distributors’ ability to access credit for purposes of funding their operations may also affect purchases of our products by these customers. If distributors reduce their purchases of our products or prices decline significantly in this distribution channel or if distributors experience financial difficulties or terminate their relationships with us, our revenues and results of operations would be adversely affected.

In addition, retail sales of our consumer solutions traditionally experience seasonal variability in demand with higher levels of demand in the first half of our fiscal year driven by consumer spending in the back-to-school season from late summer to fall and the traditional holiday shopping season from fall to winter. Our ability to reach such consumers depends on us maintaining effective working relationships with major retailers and distributors. Failure to anticipate consumer demand for our branded solutions as well as an inability to maintain effective working relationships with retail and online distributors may adversely impact our future results of operations.

Our international sales and manufacturing operations subject us to risks that may adversely affect our business related to disruptions in foreign markets, currency exchange fluctuations, longer payment cycles, seasonality, limitations imposed by a variety of legal and regulatory regimes, potential adverse tax consequences, increased costs, our customers’ credit and access to capital, health-related risks, investment risks, tariffs, privacy and protection of data and access to personnel.

We have significant sales and manufacturing operations in foreign countries, including manufacturing facilities, sales personnel and customer support operations. We have manufacturing facilities in China, Malaysia, Northern Ireland, Singapore and Thailand, in addition to those in the United States. Additionally, the manufacturing of some of our products is concentrated in certain geographical locations. The production of certain drive subassemblies are limited to Thailand and the production of media is limited to Singapore. Disruptions in the economic, environmental, political, legal or regulatory landscape in these countries may have a material adverse impact on our manufacturing operations.

Our international operations are subject to economic risks inherent in doing business in foreign countries, including the following:

• Disruptions in Foreign Markets. Disruptions in financial markets and the deterioration of the underlying economic conditions in the past in some countries, including those in Asia, United Kingdom and the European Union have had an impact on our sales to customers located in, or whose end-user customers are located in, these countries.

• Fluctuations in Currency Exchange Rates. Prices for our products are denominated predominantly in U.S. dollars, even when sold to customers that are located outside the United States. An increase in the value of the dollar could increase the real cost to our customers of our products in those markets outside of the U.S. where we sell in dollars. This could adversely impact our sales and market share in such areas or increase pressure on us to lower our price, and adversely impact our profit margins. A weakened dollar could increase the effective cost of expenses such as

Seagate Technology public limited company | 2018 Form 10-K | 22

payroll, utilities, tax, and marketing expenses, as well as overseas capital expenditures. Any of these events could have a material adverse effect on our results of operations. We may attempt to manage the impact of foreign currency exchange rate changes by, among other things, entering into foreign currency forward exchange contracts which could be designated as cash flow hedges or not designated as hedging instruments. In addition, our hedges may be ineffective, may expire and not be renewed or may not offset any or more than a portion of the adverse financial impact resulting from currency variations. The hedging activities may may not cover our full exposure, subject us to certain counterparty credit risks and may impact our results of operations. See “Item 7A. Quantitative and Qualitative Disclosures About Market Risk-Foreign Currency Exchange Risk” of this report for additional information about our foreign currency exchange risk.

• Longer Payment Cycles. Our customers outside of the United States are sometimes allowed longer time periods for payment than our U.S. customers. This increases the risk of nonpayment due to the possibility that the financial condition of particular customers may worsen during the course of the payment period.

• Seasonality. Seasonal reductions in the business activities of our customers during the summer months, particularly in Europe, and the impact of international holidays like Chinese New Year, typically result in lower earnings during those periods.

• Legal and Regulatory Limitations. Our international operations are affected by limitations on imports, tariffs, duties, currency exchange control regulations, price controls, export control laws, antitrust matters including the trade and economic sanctions administered by the Office of Foreign Assets Control, and other restraints on trade. In addition, China, Malaysia, Northern Ireland, Singapore and Thailand, in which we have significant operating assets, and the European Union have exercised and continue to exercise significant influence over many aspects of their domestic economies including, but not limited to, fair competition, tax practices, anti-corruption, anti-trust, price controls and international trade. Legislation addressing climate change and financial reform may also be enacted, generating additional federal, international or other regulatory compliance obligations. Although we have implemented policies and procedures designed to ensure compliance, there can be no assurance that our employees, contractors, or agents will not violate these or other applicable laws, rules and regulations to which we may be subject. The anti-corruption processes and controls we have implemented may be vulnerable to employee malfeasance and inadequate to fully insulate against all eventualities. Violations of these laws and regulations could lead to significant penalties, restraints on our export or import privileges, monetary fines, government investigations, disruption of our operating activities, damage to our reputation and corporate brand, criminal proceedings and regulatory or other actions that could materially adversely affect our results of operations. The political and media scrutiny surrounding a governmental investigation for the violation of such laws, even if an investigation does not result in a finding of violation, could cause us significant expense and collateral consequences, including reputational harm, that could have an adverse impact on our business, operating results and financial condition.

• Potential Adverse Tax Consequences. Our international operations create a risk of potential adverse tax consequences, including imposition of withholding or other taxes on payments by our subsidiaries. In addition, our taxable income in any jurisdiction is dependent upon acceptance of our operational practices and intercompany transfer pricing by local tax authorities as being on an arm’s length basis. Due to inconsistencies in application of the arm’s length standard among taxing authorities, as well as a lack of adequate treaty-based protection, transfer pricing challenges by tax authorities could, if successful, substantially increase our income tax expense. We are subject to tax audits around the world, and are under audit in various jurisdictions, and such jurisdictions may assess additional income tax against us. Although we believe our tax positions are reasonable, the final determination of tax audits could be materially different from our recorded income tax provisions and accruals. The ultimate results of an audit could have a material adverse effect on our operating results or cash flows in the period or periods for which that determination is made and could result in increases to our overall tax expense in subsequent periods. In light of the ongoing fiscal challenges many countries are facing, various levels of government are increasingly focused on tax reform and other legislative action to increase tax revenue. In the United States, tax reform legislation commonly known as the Tax Act has significantly changed how the U.S. taxes corporate multinationals. In response to the Tax Act, foreign governments may enact new tax laws or new interpretations of the tax laws. In addition, the Organization for Economic Cooperation and Development’s Base Erosion and Profit Shifting recommendations are reshaping international tax rules in numerous countries. These actual and potential changes in the relevant tax laws applicable to corporate multinationals, along with potential changes in accounting and other laws, regulations, administrative

Seagate Technology public limited company | 2018 Form 10-K | 23

practices, principles, and interpretations, could increase the risk of double taxation, cause increased tax audit activity, impact our effective tax rate and adversely impact our operating results, cash flows and financial condition.

• Increased Costs. The shipping and transportation costs associated with our international operations are typically higher than those associated with our U.S. operations, resulting in decreased operating margins in some foreign countries. Volatility in fuel costs, political instability or constrained in air transportation may lead us to develop alternative shipment methods, which could disrupt our ability to receive raw materials in, or ship finished product from and as a result our business and operating results may be harmed.

• Credit and Access to Capital Risks. Our international customers could have reduced access to working capital due to higher interest rates, reduced bank lending resulting from contractions in the money supply or the deterioration in the customer’s or its bank’s financial condition, or the inability to access other financing.

• Global Health Outbreaks. The occurrence of a pandemic disease may adversely impact our operations, and some of our key customers. Such diseases could also potentially disrupt the timeliness and reliability of the distribution network we rely on.

• Acquisition, Alliance, Joint Venture and Investment Risks. International acquisitions, alliances, joint ventures or investment opportunities may increase our liabilities, fail to achieve expected benefits, disrupt our existing business and adversely affect our operating results. Regulatory review and approval by governmental authorities of an alliance, acquisitions, joint venture or investment may result in additional obligations, divestitures, or restrictions on the conduct of our business or the acquired business.

• Tariffs or Other Restrictions on Foreign Imports. Changes in U.S. and international trade policy and resultant retaliatory countermeasures, including imposition of increased tariffs, quotas or duties by affected countries, and trading partners are difficult to predict and may adversely affect our business. The U.S. government has and could in the future impose trade barriers including tariffs, quotas, duties or other restrictions on foreign imports. The implementation of a border tax, tariff or higher customs duties on our products manufactured abroad or components that we import into the U.S., or any potential corresponding actions by other countries in which we do business, could negatively impact our financial performance.

• Privacy and Protection of Data. Our business is subject to a number of laws, regulations, rules, and directives in the countries where we operate pertaining to the collection, processing, security, use, retention, and transfer of personally identifiable information about our customers, consumers and employees. For example, the General Data Protection Regulation, which came into effect in the European Union (“EU”) on May 25, 2018, applies to our operations. In addition, in the U.S. federal and state laws, regulations and rules may be enacted and affect our data handling practices. The legal and regulatory environment around privacy and data protection is continuing to develop in ways we cannot predict and from country to country may be interpreted and applied inconsistently. The various laws, regulations, rules, and directives may impose conflicting or inconsistent compliance obligations and could require us to change our data practices, which could have an adverse effect on our business and results of operations. Determinations that there have been violations of privacy or data protection laws could result in adverse effects on our business and results of operations including damage to our brand, significant financial penalties, and unanticipated changes to our data handling and processing practices.

• Access to Personnel. There is substantial competition for qualified and capable personnel in certain jurisdictions in which we operate, including China, which may make it difficult for us to recruit and retain qualified employees in sufficient numbers. Factors including a perceived decrease in the retention value of our compensation package and increases in the cost of living in jurisdictions in which we operate may adversely affect our ability to attract, retain and further motivate key personnel. Increased difficulty in recruiting or retaining sufficient and adequate personnel in our international operations may lead to increased manufacturing and employment compensation costs, which could adversely affect our results of operations. The reductions in workforce that result from the restructuring plans we engage in may make it difficult for us to attract, retain and motivate highly skilled personnel and if the benefits of our restructuring plans are not realized, our operating results could be negatively affected.

Seagate Technology public limited company | 2018 Form 10-K | 24

Declines in the value of our investment in K.K. Pangea (“Pangea”) may adversely impact our financial condition and results of operations.

On May 31, 2018, we invested $1.3 billion in non-convertible preferred stock of Pangea for the acquisition of Toshiba Memory Corporation with a consortium of investors led by Bain Capital Private Equity. The investment, with a contractual maturity of six years, is accounted for as a held-to-maturity debt security, carried at amortized cost and has a contractual payment-in-kind (“PIK”) income that is accrued and added to the carrying value of the investment. If the fair value of our investment, including the accrued PIK income declines, we may be required to record impairment charges, which could have a material adverse effect on our liquidity and our results of operations. Numerous factors could cause the fair value of our investment to decline, including the credit worthiness of Pangea, adverse changes in business climate, adverse actions by regulators, or unanticipated changes in the competitive environment or the industries in which Pangea operates. Increased volatility in the financial markets and overall economic uncertainty could increase the risk that actual amounts realized on our investment may differ significantly from the fair values currently assigned to them.

We could suffer a loss of revenue and increased costs, exposure to significant liability including legal and regulatory consequences, reputational harm, and other serious negative consequences if we encounter cyber-attacks, ransomware or other cyber security breaches that disrupt our operations or result in the dissemination of proprietary or confidential information about us or our customers or other third parties.

Our operations are dependent upon our ability to protect our computer equipment and the electronic data stored in our databases from damage by, among other things, earthquake, floods, fire, natural disasters, accidents, power or water disruptions, telecommunications failures, acts of terrorism or war, employee misconduct, physical or electronic break-ins, cyber-attacks, ransomware, system security breaches or similar events or disruptions. We manage and store various proprietary information and sensitive or confidential data relating to our operations. As our operations become more automated and increasingly interdependent, our exposure to the risks posed by these types of events will increase. The measures we have implemented to secure our computer equipment and electronic data may be vulnerable to employee error, hacking, malfeasance, system error, or other irregularities and may not be sufficient for all eventualities. The insurance coverage we maintain that is intended to address certain data security risks, may be insufficient to cover all types of claims or losses that may arise. We have been, and will likely continue to be, subject to computer viruses or other malicious codes, cyber-attacks, or other computer-related attempts to breach the information technology (“IT”) systems we use for these purposes. We may also be subject to IT system failures and network disruptions due to these factors. Experienced computer programmers and hackers may be able to penetrate our network security, misappropriate or compromise our confidential information or that of third-parties, create system disruptions, or cause shutdowns. Computer programmers and hackers also may be able to develop and deploy viruses, worms, and other malicious software programs that attack our products or otherwise exploit any security vulnerabilities of our products. Such attempts are increasing in technical sophistication, number and ability to evade detection or to obscure such activities. Although we take steps to protect against and detect such attempts, our efforts may not be sufficient for all eventualities. In addition, sophisticated hardware and operating system software and applications that we produce or procure from third-parties may contain defects in design or manufacture, including “bugs” and other problems that could unexpectedly interfere with the operation of the system.

The costs to us to eliminate or address the foregoing security problems and security vulnerabilities before or after a cyber-incident could be significant. System redundancy may be ineffective or inadequate, and our disaster recovery planning may not be sufficient for all eventualities. Our remediation efforts may not be successful and could result in interruptions, delays, or cessation of service, and loss of existing or potential customers that may impede our sales, manufacturing, distribution, or other critical functions. We could lose existing or potential customers for outsourcing services or other IT solutions in connection with any actual or perceived security vulnerabilities in our products. Some of our products contain encryption and other measures to protect third-party content stored on our products. Such measures may be compromised, breached or circumvented by sophisticated attackers and losses or unauthorized access to or releases of confidential information may occur. Breaches of our security measures and the unapproved dissemination of proprietary information or sensitive or confidential data about us or our customers or other third-parties, could expose us, our vendors and customers, or other third-parties affected to a risk of loss or misuse of this information, result in litigation or governmental investigations and potential liability for us, damage our brand and reputation, or otherwise harm our business. Failure to meet our contractual obligations to promote information security with certain customers may result in liability, including additional costs, indemnification claims, litigation and damage to our brand and reputation. In addition, we rely in certain limited capacities on third-party data

Seagate Technology public limited company | 2018 Form 10-K | 25

management providers whose possible security problems and security vulnerabilities may have similar effects on us. Our business, brand and reputation could also be adversely affected by media or other reports of perceived security vulnerabilities in our products, network, or processes, even if unsubstantiated.

We are subject to laws, rules, and regulations in the U.S., U.K., EU and other countries relating to the collection, use, and security of user data. 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 ability to execute transactions and to possess and use personal information and data in conducting our business subjects us to legislative and regulatory burdens that may require us to notify vendors, customers or employees of a data security breach. We have incurred, and will continue to incur, significant expenses to comply with mandatory privacy and security standards and protocols imposed by law, regulation, industry standards, or contractual obligations. These laws, protocols and standards continue to develop and may be inconsistent from jurisdiction to jurisdiction. Complying with emerging and changing international requirements may cause us to incur substantial costs or require us to change our business practices. If we fail to comply with applicable federal, state or international privacy-related or data protection laws we may be subject to proceedings by governmental entities and incur penalties, significant legal liability, or reputational harm.

We must successfully maintain and upgrade our IT systems, and our failure to do so could have a material adverse effect on our business, financial condition and results of operations.

From time to time, we expand and improve our IT systems to support our business going forward. Consequently, we are in the process of implementing, and will continue to invest in and implement, modifications and upgrades to our IT systems and procedures, including making changes to legacy systems or acquiring new systems with new functionality, and building new policies, procedures, training programs and monitoring tools. These types of activities subject us to inherent costs and risks associated with changing and acquiring these systems, including capital expenditures, additional operating expenses, demands on management time and other risks and costs of delays or difficulties in transitioning to or integrating new systems into our current systems. These implementations, modifications and upgrades may not result in productivity improvements at a level that outweighs the costs of implementation, or at all. In addition, difficulties with implementing new technology systems, delays in our timeline for planned improvements, significant system failures, or our inability to successfully modify our IT systems to respond to changes in our business needs may cause disruptions in our business operations and have a material adverse effect on our business, financial condition and results of operations.

From time to time, we may be subject to litigation, government investigations or governmental proceedings, which may adversely impact our results of operations and financial condition.

From time to time, we may be involved in various legal, regulatory or administrative investigations, negotiations or proceedings arising in the normal course of business. In the event of litigation, government investigations or governmental proceedings, we are subject to the inherent risks and uncertainties that may result if outcomes differ from our expectations. In the event of adverse outcomes in any litigation, investigation or government proceeding, we could be required to pay substantial damages, fines or penalties, and cease certain practices or activities, which could materially harm our business.

The costs associated with litigation and government investigations can also be unpredictable depending on the complexity and length of time devoted to such litigation or investigation. Litigation, investigations or government proceedings may also divert the efforts and attention of our key personnel, which could also harm our business.

If we do not control our fixed costs, we will not be able to compete effectively in our industry.

We continually seek to make our cost structure and business processes more efficient. We are focused on increasing workforce flexibility and scalability, and improving overall competitiveness by leveraging our global capabilities, as well as external talent and skills, worldwide. Our strategy involves, to a substantial degree, increasing revenue and product volume while at the same time controlling operating expenses. If we do not control our operating expenses, our ability to compete in the marketplace may be impaired. In the past, activities to reduce operating costs have included closures and transfers of facilities, significant personnel reductions, restructuring efforts and efforts to increase automation. Our restructuring efforts may not yield the intended benefits and may be unsuccessful or disruptive to our business operations which may materially adversely affect our financial results.

If we experience shortages or delays in the receipt of, or cost increases in, critical components, equipment or raw materials necessary to manufacture our products, we may suffer lower operating margins, production delays and other material adverse effects.

The cost, quality and supply of components, subassemblies, certain equipment and raw materials used to manufacture our products and key components like recording media and heads are critical to our success. The equipment we use to manufacture our products and components is frequently custom made and comes from a few suppliers and the lead times required to obtain manufacturing equipment can be significant. Particularly important for our products are components such as read/write heads, substrates for recording media, ASICs, spindle motors, printed circuit boards, suspension assemblies and NAND flash memory.

We rely on sole suppliers or a limited number of suppliers for some or all of these components that we do not manufacture, including substrates for recording media, read/write heads, ASICs, spindle motors, printed circuit boards, suspension assemblies and NAND flash memory. Many of such component suppliers are geographically concentrated which makes our supply chain more vulnerable to regional disruptions such as severe weather, acts of terrorism and an unpredictable geopolitical climate which may have a material impact on the production and availability of many components. If our vendors for these components are unable to meet our cost, quality, and supply requirements, continue to remain financially viable or fulfill their contractual commitments and obligations, we could experience a shortage in supply or an increase in production costs, which would materially adversely affect our results of operations.

Certain rare earth elements are critical in the manufacture of our products. We purchase components that contain rare earth elements from a number of countries, including China. We cannot predict whether any nation will impose regulations or trade barriers including tariffs, duties, quotas or embargoes upon the rare earth elements incorporated into our products that would restrict the worldwide supply of such metals or increase their cost. We have experienced increased costs and production delays when we were unable to obtain the necessary equipment or sufficient quantities of some components, and/or have been forced to pay higher prices or make volume purchase commitments or advance deposits for some components, equipment or raw materials that were in short supply in the industry in general. Further, if our customers experience shortages of components or materials used in their products it could result in a decrease in demand for our products and have an adverse effect on our results of operations. If any major supplier were to restrict the supply available to us or increase the cost of the rare earth elements used in our products, we could experience a shortage in supply or an increase in production costs, which would adversely affect our results of operations.

Consolidation among component manufacturers has resulted and may continue to result in some component manufacturers exiting the industry or not making sufficient investments in research to develop new components.

If there is a shortage of, or delay in supplying us with, critical components, equipment or raw materials, then:

• it is likely that our suppliers would raise their prices and, if we could not pass these price increases to our customers, our operating margin would decline;

• we may have to reengineer some products, which would likely cause production and shipment delays, make the reengineered products more costly and provide us with a lower rate of return on these products;

• we would likely have to allocate the components we receive to certain of our products and ship less of others, which could reduce our revenues and could cause us to lose sales to customers who could purchase more of their required products from manufacturers that either did not experience these shortages or delays or that made different allocations; and

• we may be late in shipping products, causing potential customers to make purchases from our competitors, thus causing our revenue and operating margin to decline.

We cannot assure you that we will be able to obtain critical components in a timely and economic manner. Many of our suppliers’ manufacturing facilities are fully utilized. If they fail to invest in capacity or in the required timeframe, such failure would have an impact on our ability to ramp new products, and may result in a loss of revenue or market share if our competitors did not utilize the same components and were not affected.

We often aim to lead the market in new technology deployments and leverage unique and customized technology from single source suppliers who are early adopters in the emerging market. Our options in supplier selection in these cases are

Seagate Technology public limited company | 2018 Form 10-K | 27

limited and the supplier based technology may consequently be single sourced until wider adoption of the technology occurs and any necessary licenses become available. In such cases, any technical issues in the supplier’s technology may cause us to delay shipments of our new technology deployments and harm our financial position.

If revenues fall or customer demand decreases significantly, we may not meet all of our purchase commitments to certain suppliers.

From time to time, we enter into long-term, non-cancelable purchase commitments or make large up-front investments with certain suppliers in order to secure certain components or technologies for the production of our products or to supplement our internal manufacturing capacity for certain components. If our actual revenues in the future are lower than our projections or if customer demand decreases significantly below our projections, we may not meet all of our purchase commitments with these suppliers. As a result, it is possible that our revenues will not be sufficient to recoup our up-front investments, in which case we will have to shift output from our internal manufacturing facilities to these suppliers or make penalty-type payments under the terms of these contracts. Additionally, because our markets are volatile, competitive and subject to rapid technology and price changes, we face inventory and other asset risks in the event we do not fully utilize firm purchase commitments.

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

In August 2012, the SEC adopted rules establishing additional disclosure and reporting requirements regarding the use of specified minerals, or conflict minerals, that are necessary to the functionality or production of products manufactured or contracted to be manufactured. These rules may require us to determine, disclose and report whether or not such conflict minerals originate from the Democratic Republic of the Congo or an adjoining country. These rules could affect our ability to source, directly or indirectly, certain materials used in our products at competitive prices and could impact the availability of certain minerals used in the manufacture of our products, including gold, tantalum, tin and tungsten. As there may be only a limited number of suppliers of “conflict free” minerals, we cannot be sure that we will be able to obtain necessary conflict free minerals in sufficient quantities or at competitive prices. Our customers, including our OEM customers, may require that our products be free of conflict minerals, and our revenues and margins may be harmed if we are unable to procure conflict free minerals at a reasonable price, or at all, or are unable to pass through any increased costs associated with meeting these demands. Additionally, we may face reputational challenges with our customers and our manufacturing stakeholders if we are unable to sufficiently verify the origins of all minerals used in our products through the due diligence procedures that we implement. We may also face challenges with government regulators and our customers and suppliers if we are unable to sufficiently verify that the metals used in our products are conflict free. We expect that there may be material costs associated with complying with the disclosure requirements, such as costs related to determining the source of certain minerals used in our products, as well as costs related to possible changes to products, processes, or sources of supply as a consequence of such verification and disclosure requirements. Additionally, the regulatory and compliance framework for conflict minerals may undergo changes which may further increase the cost of compliance. Our customers and manufacturing stakeholders may place increased demands on our compliance framework which may in turn negatively impact our relationships with our suppliers.

The loss of key executive officers and employees could negatively impact our business prospects.

Our future performance depends to a significant degree upon the continued service of key members of management as well as marketing, sales and product development personnel. The loss of one or more of our key personnel may have a material adverse effect on our business, results of operations and financial condition. We believe our future success will also depend in large part upon our ability to attract, retain and further motivate highly skilled management, marketing, sales and product development personnel. We have experienced intense competition for personnel, and we cannot assure you that we will be able to retain our key employees or that we will be successful in attracting, assimilating and retaining personnel in the future.

Due to the complexity of our products, some defects may only become detectable after deployment.

Our products are highly complex and are designed to operate in and form part of larger complex networks and storage systems. Our products may contain a defect or be perceived as containing a defect by our customers, as a result of improper use or maintenance. Lead times required to manufacture certain components are significant, and a quality excursion may take

Seagate Technology public limited company | 2018 Form 10-K | 28

significant time and resources to remediate. Defects in our products, third-party components, or in the networks and systems of which they form a part, directly or indirectly, have resulted in and may in the future result in:

• increased costs and product delays until complex solution level interoperability issues are resolved;

• costs associated with the remediation of any problems attributable to our products;

• loss of or delays in revenues;

• loss of customers;

• failure to achieve market acceptance and loss of market share;

• increased service and warranty costs; and

• increased insurance costs.

Defects in our products could also result in legal actions by our customers for property damage, injury or death. Such legal actions, including but not limited to product liability claims could exceed the level of insurance coverage that we have obtained. Any significant uninsured claims could significantly harm our financial condition.

Political events, war, terrorism, natural disasters, public health issues and other circumstances could materially adversely affect our results of operations and financial condition.

War, terrorism, geopolitical uncertainties, natural disasters, public health issues and other business interruptions have caused and could cause damage or disruption to international commerce and the global economy, and thus could have a strong negative effect on our business, our suppliers, logistics providers, manufacturing vendors and customers. Our business operations are subject to interruption by natural disasters such as floods and earthquakes, fires, power or water shortages, terrorist attacks, other hostile acts, labor disputes, public health issues, and other events beyond our control. Such events may decrease demand for our products, make it difficult or impossible for us to make and deliver products to our customers, or to receive components from our suppliers, and create delays and inefficiencies in our supply chain. In the event of a natural disaster, losses and significant recovery time could be required to resume operations and our financial condition and operating results could be materially adversely affected. Should major public health issues, including pandemics, arise, we could be negatively affected by stringent employee travel restrictions, additional limitations in freight services, governmental actions limiting the movement of products between regions, delays in production ramps of new products, and disruptions in our operations and some of our key customers.

Failure to comply with applicable environmental laws and regulations could have a material adverse effect on our business, results of operations and financial condition.

The sale and manufacturing of products in certain states and countries may subject us and our suppliers to state, federal and international laws and regulations governing protection of the environment, including those governing discharges of pollutants into the air and water, the management and disposal of hazardous substances and wastes, the cleanup of contaminated sites, restrictions on the presence of certain substances in electronic products and the responsibility for environmentally safe disposal or recycling. We endeavor to ensure that we and our suppliers comply with all applicable environmental laws and regulations, however, compliance may increase our operating costs and otherwise impact future financial results. If additional or more stringent requirements are imposed on us in the future, we could incur additional operating costs and capital expenditures. If we fail to comply with applicable environmental laws, regulations, initiatives, or standards of conduct, our customers may refuse to purchase our products and we could be subject to fines, penalties and possible prohibition of sales of our products into one or more states or countries, liability to our customers and damage to our reputation, which could result in a material adverse effect on our financial condition or results of operations.

Any cost reduction initiatives that we undertake may not deliver the results we expect, and these actions may adversely affect our business.

From time to time, we engage in restructuring plans that may result in workforce reduction and consolidation of our real estate facilities and our manufacturing footprint. In addition, management will continue to evaluate our global footprint and cost

Seagate Technology public limited company | 2018 Form 10-K | 29

structure, and additional restructuring plans are expected to be formalized. As a result of our restructuring, we may experience a loss of continuity, loss of accumulated knowledge, disruptions to our operations and inefficiency during transitional periods. Additionally, global footprint consolidation and reduction in excess capacity may result in us being unable to respond to increase in forecasted volume of customer demand and loss of revenue opportunity if our competitors have underutilized factories. Any cost-cutting measures could impact employee retention. In addition, we cannot be sure that the cost reduction and global footprint consolidation will be successful in reducing our overall expenses as we expect or that additional costs will not offset any such reductions or global footprint consolidation. If our operating costs are higher than we expect or if we do not maintain adequate control of our costs and expenses, our results of operations may be adversely affected.

Our ability to use our net operating loss and tax credit carryforwards might be limited.

The use of a portion of our U.S. net operating loss and tax credit carryforwards is subject to annual limitations pursuant to U.S. tax law. Section 382 of the U.S. Internal Revenue Code generally imposes an annual limitation on the amount of net operating loss or tax credit carryforwards that might be used to offset taxable income when a corporation has undergone significant changes in ownership. As a result, future changes in ownership could put further limitations on the availability of our net operating loss or tax credit carryforwards.

Deterioration in global credit and financial market conditions could negatively impact the value of our current portfolio of cash equivalents or short-term investments and our ability to meet our financing objectives.

Our cash and cash equivalents are maintained in highly liquid investments with remaining maturities of 90 days or less at the time of purchase. Our short-term investments may include readily marketable debt securities with remaining maturities of more than 90 days at the time of purchase. Our investment policy has as its principal objectives the preservation of principal and maintenance of liquidity. We mitigate default risk by investing in high-quality investment grade securities with different counterparties, limiting the time to maturity and by monitoring the counterparties and underlying obligors closely.

We are not aware of any current material downgrades, losses, or other significant deterioration in the fair value of our cash equivalents or short-term investments, however, no assurance can be given that future deterioration in conditions of the global credit and financial markets would not negatively impact our current portfolio of cash equivalents or short-term investments or our ability to meet our financing objectives.

We are at times subject to intellectual property legal proceedings and claims which could cause us to incur significant additional costs or prevent us from selling our products, and which could adversely affect our results of operations and financial condition.

We are subject from time-to-time to legal proceedings and claims, including claims of alleged infringement of the patents, trademarks and other intellectual property rights of third parties by us, or our customers, in connection with their use of our products. Intellectual property litigation can be expensive and time-consuming, regardless of the merits of any claim, and could divert our management’s attention from operating our business. In addition, intellectual property lawsuits are subject to inherent uncertainties due to the complexity of the technical issues involved, which may cause actual results to differ materially from our expectations. Patent litigation has increased due to the current uncertainty of the law and the increasing competition and overlap of product functionality in the field. Some of the actions that we face from time-to-time seek injunctions against the sale of our products and/or substantial monetary damages, which if granted or awarded, could materially harm our business, financial condition and operating results.

We cannot be certain that our products do not and will not infringe issued patents or other intellectual property rights of others. We may not be aware of currently filed patent applications that relate to our products or technology. If patents are later issued on these applications, we may be liable for infringement. If our products were found to infringe the intellectual property rights of others, we could be required to pay substantial damages, cease the manufacture, use and sale of infringing products in one or more geographic locations, expend significant resources to develop non-infringing technology, discontinue the use of specific processes or obtain licenses to the technology infringed. We might not be able to obtain the necessary licenses on acceptable terms, or at all, or be able to reengineer our products successfully to avoid infringement. Any of the foregoing could cause us to incur significant costs and prevent us from selling our products, which could adversely affect our results of operations and financial condition. See “Item 8. Financial Statements and Supplementary Data-Note 14. Legal, Environmental and Other Contingencies” contained in this report for a description of pending intellectual property proceedings.

Seagate Technology public limited company | 2018 Form 10-K | 30

We may be unable to protect our intellectual property rights, which could adversely affect our business, financial condition and results of operations.

We rely on a combination of patent, trademark, copyright and trade secret laws, confidentiality procedures and licensing arrangements to protect our intellectual property rights. In the past, we have been involved in significant and expensive disputes regarding our intellectual property rights and those of others, including claims that we may be infringing patents, trademarks and other intellectual property rights of third-parties. We expect that we will be involved in similar disputes in the future.

There can be no assurance that:

• any of our existing patents will continue to be held valid, if challenged;

• patents will be issued for any of our pending applications;

• any claims allowed from existing or pending patents will have sufficient scope or strength to protect us;

• our patents will be issued in the primary countries where our products are sold in order to protect our rights and potential commercial advantage;

• we will be able to protect our trade secrets and other proprietary information through confidentiality agreements with our customers, suppliers and employees and through other security measures; and

• others will not gain access to our trade secrets.

In addition, our competitors may be able to design their products around our patents and other proprietary rights. 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 counter sue us for infringement of their patents or assert a counterclaim that our patents are invalid or unenforceable.

Furthermore, we have significant operations and sales in foreign countries where intellectual property laws and enforcement policies are often less developed, less stringent or more difficult to enforce than in the United States. Therefore, we cannot be certain that we will be able to protect our intellectual property rights in jurisdictions outside the United States.

The price of our ordinary shares may be volatile and could decline significantly.

The stock market, in general, and the market for technology stocks in particular, has experienced volatility that has often been unrelated to the operating performance of companies. If these market or industry-based fluctuations continue to occur in the future, the trading price of our ordinary shares could decline significantly independent of our actual operating performance, and shareholders could lose all or a substantial part of their investment. The market price of our ordinary shares could fluctuate significantly in response to several factors, including among others:

• general uncertainty in stock market conditions occasioned by global economic conditions, negative financial news and the continued instability of several large financial institutions;

• actual or anticipated variations in our results of operations;

• announcements of innovations, new products or significant price reductions by us or our competitors, including those competitors who offer alternative storage technology solutions;

• our failure to meet the performance estimates of investment research analysts;

• the timing of announcements by us or our competitors of significant contracts or acquisitions;

• general stock market conditions;

• the occurrence of major catastrophic events;

• changes in financial estimates by investment research analysts;

• actual or anticipated changes in the credit ratings of our indebtedness by rating agencies; and

• the sale of our ordinary shares held by certain equity investors or members of management.

Seagate Technology public limited company | 2018 Form 10-K | 31

In the past, following periods of decline in the market price of a company’s securities, class action lawsuits have often been pursued against that company. If similar litigation were pursued against us, it could result in substantial costs and a diversion of management’s attention and resources, which could materially adversely affect our results of operations, financial condition and liquidity.

Any decision to reduce or discontinue the payment of cash dividends to our shareholders or the repurchase of our ordinary shares pursuant to our previously announced share repurchase program could cause the market price of our ordinary shares to decline significantly.

Although we have announced targeted regular cash dividend amounts and a share repurchase program, we are under no obligation to pay cash dividends to our shareholders in the future at the announced targeted levels or at all or to repurchase our ordinary shares at any particular price or at all. The declaration and payment of any future dividends is at the discretion of our Board of Directors and our previously announced share repurchase program may be suspended or discontinued at any time. Our payment of quarterly cash dividends and the repurchase of our ordinary shares pursuant to our share repurchase program are subject to, among other things, our financial position and results of operations, available cash and cash flow, capital and regulatory requirements, market and economic conditions, our ordinary share price and other factors. Any reduction or discontinuance by us of the payment of quarterly cash dividends or the repurchase of our ordinary shares pursuant to our share repurchase program could cause the market price of our ordinary shares to decline significantly. Moreover, in the event our payment of quarterly cash dividends or repurchases of our ordinary shares are reduced or discontinued, our failure to resume such activities at historical levels could result in a persistent lower market valuation of our ordinary shares.

Our Company

We are a leading provider of data storage technology and solutions. Our principal products are hard disk drives, commonly referred to as disk drives, hard drives or HDDs. In addition to HDDs, we produce a broad range of data storage products including solid state drives (“SSDs”), solid state hybrid drives (“SSHDs”) and storage subsystems.

Hard disk drives are devices that store digitally encoded data on rapidly rotating disks with magnetic surfaces. Disk drives continue to be the primary medium of mass data storage due to their performance attributes, high quality and cost effectiveness. Complementing existing data center storage architecture, solid-state storage devices use integrated circuit assemblies as memory to store data, and most SSDs use NAND flash memory. In addition to HDDs and SSDs, SSHDs combine the features of SSDs and HDDs in the same unit, containing a high capacity hard disk drive and a smaller SSD acting as a cache to improve performance of frequently accessed data.

Our HDD products are designed for mission critical and nearline applications in enterprise servers and storage systems; edge compute/client compute applications, where our products are designed primarily for desktop and mobile computing; and edge non-compute/client non-compute applications, where our products are designed for a wide variety of end user devices such as portable external storage systems, surveillance systems, digital video recorders (“DVRs”), network-attached storage

Seagate Technology public limited company | 2018 Form 10-K | 39

(“NAS”) and gaming consoles. Our SSD products mainly include serial attached SCSI (“SAS”) and Non-Volatile Memory Express (“NVMe”) SSDs.

Our cloud systems and solutions portfolio includes modular original equipment manufacturer (“OEM”) storage systems and scale-out storage servers.

Business Overview

Our industry is characterized by several trends and factors that have a material impact on our strategic planning, financial condition and results of operations.

Demand for Data Storage

The International Data Corporation (“IDC”) forecasted in its 2017 Data Age 2025 study that the global datasphere will grow to 163 zettabytes by 2025. According to IDC, we are fast approaching a new era of the data age, which we expect will have a positive impact on storage demand. We believe that the continued advancement of the cloud, the further development of edge computing, the global proliferation of mobile devices, the evolution of the Internet of Things (“IoT”), the increasing use of video surveillance, the evolution of consumer electronic devices, and the enterprise use of big data analytics are driving the growth of digital content. Factors contributing to the growth of digital content include:

• Creation, sharing, and consumption of media-rich digital content, such as high-resolution photos, high definition videos, and digital music through smart phones, tablets, digital cameras, personal video cameras, DVRs, gaming consoles or other digital devices;

• Creation, aggregation and distribution of digital content through services and other offerings such as Facebook^®, Instagram^®, iTunes^®, Netflix^®, Google^® and YouTube^®;

• Increasing use of video surveillance and the emergence of new surveillance systems which feature higher resolution digital cameras and thus require larger data storage capacities;

• Creation and collection of data through the development and evolution of the IoT ecosystem, big data analytics (including enterprise use of big data analytics) and new technology trends such as self-driving cars and drones;

• Continued advancement of the cloud, including the build out of large numbers of cloud data centers by CSPs and private companies transitioning on-site data centers into the cloud; and

• Protection of increased digital content through redundant storage on backup devices and externally provided storage services.

As a result of these factors, we anticipate that the nature and volume of content being created will require greater storage, which is more efficiently and economically facilitated by higher capacity storage devices in order to store, manage, distribute, analyze and backup such content. We expect this to support the growth in demand for data storage solutions in developed and emerging economies.

In addition, the economics of storage infrastructure are also evolving with the utilization of public and private hyper-scale storage and open-source solutions reducing the total cost of ownership of storage while increasing the speed and efficiency with which customers can leverage massive computing and storage devices. Accordingly, we expect these trends will continue to create significant demand for data storage solutions going forward.

Demand Trends

We believe that continued growth in digital content requires increasingly higher storage capacity in order to store, aggregate, host, distribute, analyze, manage, protect, backup and use such content. We also believe that as architectures evolve to serve the growing commercial and consumer user base throughout the world, the storage solutions will evolve as well.

We expect increased data creation will lead to the expansion of the need for storage in the form of both HDDs and SSDs. While the advance of solid state technology in many end markets is expected to increase, we believe that in the foreseeable

Seagate Technology public limited company | 2018 Form 10-K | 40

future, cloud, traditional enterprise, client and consumer markets that require high-capacity storage solutions will be best served by hard disk drives due to their ability to deliver the most cost effective, reliable and energy efficient mass storage devices. We also believe that as hard disk drive capacities continue to increase, a focus exclusively on unit demand does not reflect the increase in demand for exabytes. This has resulted in demand for fewer units, but with higher average capacity per drive.

Industry Supply Balance

From time to time, the storage industry has experienced periods of imbalance between supply and demand. To the extent that the storage industry builds or maintains capacity based on expectations of demand that do not materialize, price erosion may become more pronounced. Conversely, during periods where demand exceeds supply, price erosion is generally muted.

Price Erosion

Historically, our industry has been characterized by price declines for disk drive products with comparable capacity, performance and feature sets (“like-for-like products”). Price declines for like-for-like products (“price erosion”) tend to be more pronounced during periods of:

• economic contraction in which competitors may use discounted pricing to attempt to maintain or gain market share;

• few new product introductions when competitors have comparable or alternative product offerings; and

• industry supply exceeding demand.

Disk drive manufacturers typically attempt to offset price erosion with an improved mix of disk drive products characterized by higher capacity, better performance and additional feature sets and product cost reductions.

We believe the HDD industry experienced modest price erosion in fiscal years 2016, 2017 and 2018.

Product Life Cycles and Changing Technology

Success in our industry has been dependent to a large extent on the ability to balance the introduction and transition of new products with time-to-volume, performance, capacity and quality metrics at a competitive price, level of service and support that our customers expect. Generally, the drive manufacturer that introduces a new product first benefits from improved product mix, favorable profit margins and less pricing pressure until comparable products are introduced. Changing technology also necessitates on-going investments in research and development, which may be difficult to recover due to rapid product life cycles and economic declines. Further, there is a continued need to successfully execute product transitions and new product introductions, as factors such as quality, reliability and manufacturing yields continue to be of significant competitive importance.

Seasonality

The disk drive industry traditionally experiences seasonal variability in demand with higher levels of demand in the second half of the calendar year. This seasonality is driven by consumer spending in the back-to-school season from late summer to fall and the traditional holiday shopping season from fall to winter. Beyond traditional seasonality, variability of sales can be related to IT spending or a reflection of more cyclical demand from CSPs based on the timing of procurement, deployment and market supply and demand balance of other components such as NAND and DRAM.

Fiscal Year 2018 Summary

During fiscal year 2018, we shipped 338 exabytes of HDD storage capacity. We generated revenue of $11.2 billion and gross margins of 30% and our operating cash flow was $2.1 billion. We invested $1.3 billion in non-convertible preferred stock of K.K. Pangea for the acquisition of Toshiba Memory Corporation with a consortium of investors led by Bain Capital Private Equity. We paid $726 million in dividends, repurchased approximately 10 million of our ordinary shares for $361 million and paid $214 million for the repurchase of certain of our outstanding debt.

Product Development Expense. Product development expenses for fiscal year 2018 decreased by $206 million from fiscal year 2017 primarily due to a $97 million decrease in salaries and related benefits as a result of the restructuring of our workforce in prior periods, an $83 million decrease due to related operational efficiencies and a $26 million decrease due to impairment charges related to the closure of our Korea design center in fiscal year 2017 that did not recur in fiscal year 2018.

Marketing and Administrative Expense. Marketing and administrative expenses for fiscal year 2018 decreased by $44 million from fiscal year 2017 primarily due to a $54 million decrease in salaries and related benefits as a result of the restructuring of our workforce in prior periods, partially offset by an increase in other general expenses.

Amortization of Intangibles. Amortization of intangibles for fiscal year 2018 decreased by $51 million, as compared to fiscal year 2017, due to certain intangible assets reaching the end of their useful life.

Restructuring and Other, net. Restructuring and other, net for fiscal year 2018 was comprised primarily of restructuring charges recorded during the September 2017 quarter and December 2017 quarter to reduce our workforce by approximately 1,100 employees. Restructuring and other, net also included a gain of $25 million from the sale of certain properties previously classified as held for sale.

Restructuring and other, net for fiscal year 2017 was comprised of restructuring charges recorded during the September 2016 quarter and March 2017 quarter to reduce our workforce by approximately 6,800 employees, as we continue to consolidate our global footprint across Asia, EMEA and the Americas.

Provision for income taxes	$	236	$	43	$	193		449	%

Seagate Technology public limited company | 2018 Form 10-K | 44

We recorded an income tax provision of $236 million for fiscal year 2018 compared to an income tax provision of $43 million for fiscal year 2017. Our fiscal year 2018 income tax provision included approximately $204 million of tax expense associated with the revaluation of U.S. deferred tax assets as a result of the enactment of the Tax Act on December 22, 2017, offset by the reversal of previously recorded unrecognized tax benefits of $7 million, and certain non-recurring items. Our fiscal year 2017 income tax provision included approximately $2 million of net tax expense associated with various non-recurring items.

Our Irish tax resident parent holding company owns various U.S. and non-U.S. subsidiaries that operate in multiple non-Irish income tax jurisdictions. Our worldwide operating income is either subject to varying rates of income tax or is exempt from income tax due to tax incentive programs we operate under in Malaysia, Singapore and Thailand. These tax incentives are scheduled to expire in whole or in part at various dates through 2027.

Our income tax provision recorded for fiscal year 2018 differed from the provision for income taxes that would be derived by applying the Irish statutory rate of 25% to income before income taxes, primarily due to the net effect of (i) tax benefits related to non-U.S. earnings generated in jurisdictions that are subject to tax incentive programs and are considered indefinitely reinvested outside of Ireland, and (ii) a reduction in the net U.S. deferred tax assets associated with revaluation to a lower U.S. tax rate. Our income tax provision recorded for fiscal year 2017 differed from the provision for income taxes that would be derived by applying the Irish statutory rate of 25% to income before income taxes, primarily due to the net effect of (i) tax benefits related to non-U.S. earnings generated in jurisdictions that are subject to tax incentive programs and are considered indefinitely reinvested outside of Ireland, (ii) a decrease in valuation allowance for certain deferred tax assets, and (iii) permanent differences.

Based on our non-U.S. ownership structure and subject to (i) potential future increases in our valuation allowance for deferred tax assets; and (ii) a future change in our intention to indefinitely reinvest earnings from our subsidiaries outside of Ireland, we anticipate that our effective tax rate in future periods will generally be less than the Irish statutory rate.

At June 29, 2018, our deferred tax asset valuation allowance was approximately $1.2 billion.

At June 29, 2018, we had net deferred tax assets of $410 million. The realization of most of these deferred tax assets is primarily dependent on our ability to generate sufficient U.S. and certain non-U.S. taxable income in future periods. Although realization is not assured, we believe that it is more likely than not that these deferred tax assets will be realized. The amount of deferred tax assets considered realizable, however, may increase or decrease in subsequent periods when we re-evaluate the underlying basis for our estimates of future U.S. and certain non-U.S. taxable income.

As of June 29, 2018, approximately $501 million and $99 million of our total U.S. net operating loss and tax credit carry- forwards, respectively, are subject to annual limitations from $1 million to $45 million pursuant to U.S. tax law.

We are required to file U.S. federal, U.S. state, and non-U.S. income tax returns. We are no longer subject to tax examination of U.S. federal income tax returns for years prior to fiscal year 2015. With respect to U.S. state and non-U.S. income tax returns, we are generally no longer subject to tax examination for years ending prior to fiscal year 2007.

On December 22, 2017, the Tax Act was enacted into law in the United States. The Tax Act significantly revises U.S. corporate income tax law by, among other things, lowering U.S. corporate income tax rates from 35% to 21%, implementing a territorial tax system, and imposing a one-time transition tax on deemed repatriated earnings of non-U.S. subsidiaries.

Pursuant to SEC Staff Accounting Bulletin (“SAB”) 118 (regarding the application of ASC 740 associated with the enactment of the Tax Act), we recorded an adjusted tax expense of approximately $204 million for fiscal year 2018, to re-measure our net U.S. deferred tax assets at the newly enacted 21% income tax rate. This tax expense increased our effective tax rate by approximately 14%. We also do not expect the one-time transition tax to have a material impact on our consolidated financial statements due to an overall accumulated earnings deficit in our non-U.S. subsidiaries for which the transition tax applies. We have considered SAB 118 and believe the accounting under ASC 740 for the change to the U.S. statutory tax rate to our deferred tax balances and the one-time transition tax under the Tax Act is complete and appropriately reflected in the financial statements during fiscal year 2018.

For all other provisions relating to the Tax Act, we continue to evaluate the impact of the Tax Act’s various highly complex domestic and international provisions. The other U.S. tax changes, including limitations on various business deductions such

Seagate Technology public limited company | 2018 Form 10-K | 45

as executive compensation under Internal Revenue Code §162(m), are not expected to impact our tax expense in the short-term due to our large net operating loss and tax credit carryovers and associated valuation allowance. The Tax Act’s new international rules, including Global Intangible Low-Taxed Income (“GILTI”), Foreign Derived Intangible Income (“FDII”), and Base Erosion Anti-Avoidance Tax (“BEAT”) are generally effective in tax years beginning after December 31, 2017. These provisions are not expected to have a material impact on our consolidated financial statements. However, these preliminary assessments and analyses are provisional and are subject to change as additional interpretive guidance is issued. We will complete our analysis within fiscal year 2019, which is consistent with the guidance provided in SAB 118.

Product Development Expense. Product development expenses for fiscal year 2017 decreased from fiscal year 2016 primarily due to a $102 million decrease in salaries and related benefits as a result of an increase in operational efficiencies in our business and the restructuring of our workforce in prior periods, offset by a $71 million increase in variable compensation and share-based compensation driven by better financial performance of the Company and a $26 million increase in impairment charges related to the closure of our Korea design center.

Seagate Technology public limited company | 2018 Form 10-K | 46

Marketing and Administrative Expense. Marketing and administrative expenses for fiscal year 2017 decreased from fiscal year 2016 primarily due to a decrease in salaries and related benefits of $52 million as a result of the restructuring of our workforce in prior periods, a $28 million cost reduction resulting from an increase in operational efficiencies in our business and the completion of certain promotional and branding activities in fiscal year 2016, partially offset by a $51 million increase in variable compensation and share-based compensation driven by better financial performance of the Company.

Amortization of Intangibles. Amortization of intangibles for fiscal year 2017 decreased by $19 million, as compared to fiscal year 2016, due to certain intangible assets reaching the end of their useful life.

Restructuring and Other, net. Restructuring and other, net for fiscal year 2017 was comprised primarily of restructuring charges recorded during the September 2016 quarter and March 2017 quarter to reduce our workforce by approximately 6,800 employees, to consolidate our global footprint across Asia, EMEA and the Americas.

Restructuring and other, net for fiscal year 2016 comprised of restructuring charges recorded during the September 2015 quarter, March 2016 quarter and June 2016 quarter, to reduce our workforce by approximately 4,600 employees and align our manufacturing footprint with current macroeconomic conditions.

Other expense, net for fiscal year 2017 increased by $68 million, as compared to fiscal year 2016 primarily due to the $33 million of other income associated with the final payment of unpaid interest on the arbitration award amount in the Company’s case against Western Digital in fiscal year 2016 which did not recur in fiscal year 2017, a $12 million increase from impairment of certain strategic investments and $24 million interest expense on the issuance of $750 million of 4.25% Senior Notes due 2022 and $500 million of 4.875% Senior Notes due 2024.

Provision for income taxes	$	43	$	26	$	17		65	%

We recorded an income tax provision of $43 million for fiscal year 2017 compared to an income tax provision of $26 million for fiscal year 2016. Our fiscal year 2017 income tax provision included approximately $2 million of net income tax expense associated with various non-recurring items. Our fiscal year 2016 income tax provision included approximately $22 million of net income tax benefits primarily associated with the release of tax reserves due to the expiration of certain statutes of limitation.

Our income tax provision recorded for fiscal year 2017 differed from the provision for income taxes that would be derived by applying the Irish statutory rate of 25% to income before income taxes, primarily due to the net effect of (i) tax benefits related to non-U.S. earnings generated in jurisdictions that are subject to tax incentive programs and are considered indefinitely reinvested outside of Ireland, (ii) a decrease in valuation allowance for certain deferred tax assets, and (iii) permanent differences. Our income tax provision recorded for fiscal year 2016 differed from the provision for income taxes that would be derived by applying the Irish statutory rate of 25% to income before income taxes, primarily due to the net effect of (i) tax benefits related to non-U.S. earnings generated in jurisdictions that are subject to tax incentive programs and are considered indefinitely reinvested outside of Ireland, (ii) tax benefits associated with the reversal of previously recorded taxes, and (iii) a decrease in valuation allowance for certain deferred tax assets. The acquisition of Dot Hill System Corporation did not have a material impact on our effective tax rate.

On December 18, 2015, the Protecting Americans from Tax Hikes (“PATH”) Act of 2015 was enacted. Among other provisions, the PATH Act retroactively reinstated and permanently extended the federal Research and Development (R&D) tax credit from December 31, 2014. The permanent extension of the R&D credit had no immediate impact on our income tax provision due to valuation allowances on our U.S. deferred tax assets. None of the other PATH Act changes had a material impact on our income tax provision.

Liquidity and Capital Resources

The following sections discuss our principal liquidity requirements, as well as our sources and uses of cash and our liquidity and capital resources. Our cash and cash equivalents are maintained in investments with remaining maturities of 90 days or less at the time of purchase. Our short-term investments consist primarily of money market funds, time deposits and certificates of deposit. The principal objectives of our investment policy are the preservation of principal and maintenance of liquidity. We believe our cash equivalents and short-term investments are liquid and accessible. We operate in some countries that have restrictive regulations over the movement of cash and/or foreign exchange across their borders. However, we believe our sources of cash have been and will continue to be sufficient to meet our cash needs for the next 12 months. We are not aware of any downgrades, losses or other significant deterioration in the fair value of our cash equivalents or short-term investments and we do not believe the fair value of our short-term investments has significantly changed from the values reported as of June 29, 2018.

Cash and cash equivalents	$	1,853	$	2,539	$	(686	)

Our cash and cash equivalents decreased by $686 million from June 30, 2017 as a result of $1.3 billion investment in non-convertible preferred stock of K.K. Pangea, net cash outflows for capital expenditures of $366 million, dividends paid out to shareholders of $726 million, repurchase of our ordinary shares of $361 million and repayment of long-term debt of $214 million. These decreases were offset by net cash provided by operating activities. The following table summarizes results from the Consolidated Statement of Cash Flows for the periods indicated:

Cash Provided by Operating Activities

Cash provided by operating activities for fiscal year 2018 was approximately $2.1 billion and includes the effects of net income adjusted for non-cash items including depreciation and amortization, deferred income taxes primarily due to the remeasurement of our U.S. deferred tax assets at the lower corporate tax rate, share-based compensation, and:

• an increase of $65 million in accounts payable, primarily due to timing of payments of capital expenditures; and

• a decrease of $71 million in vendor receivables, primarily due to improved collections; partially offset by

• an increase of $71 million in inventory, primarily due to an increase in units built.

Seagate Technology public limited company | 2018 Form 10-K | 48

Cash provided by operating activities for fiscal year 2017 was approximately $1.9 billion and includes the effects of net income adjusted for non-cash items including depreciation and amortization, share-based compensation, and:

• a decrease of $122 million in accounts receivable, primarily due to a decrease in revenue and improved collections; and

• an increase of $121 million in accounts payable, primarily due to timing of payments for material purchases; partially offset by

• an increase of $114 million in inventory, primarily due to an increase in units built in connection with our manufacturing footprint consolidating activities.

Cash provided by operating activities for fiscal year 2016 was approximately $1.7 billion and includes the effects of net income adjusted for non-cash items including depreciation and amortization, share-based compensation and

• a decrease in revenue accelerated by a reduction in the cash conversion cycle, leading to a decrease in working capital.

Cash Used in Investing Activities

In fiscal year 2018, we used $1.6 billion for net cash investing activities, which was primarily due to our investment in the Pangea debt security of $1.3 billion and the payments for the purchase of property, equipment and leasehold improvements of approximately $366 million, partially offset by the proceeds of $69 million from the sale of certain properties previously classified as held for sale.

In fiscal year 2017, we used $459 million for net cash investing activities, which was primarily due to payments for the purchase of property, equipment and leasehold improvements of approximately $434 million.

In fiscal year 2016, we used $1.2 billion for net cash investing activities, which was primarily due to payments for the purchase of property, equipment and leasehold improvements of approximately $587 million and the acquisition of Dot Hill, net of cash acquired for $634 million.

Cash Used in Financing Activities

Net cash used in financing activities of $1.2 billion for fiscal year 2018 was primarily attributable to the following activities:

• $726 million in dividend payments;

• $361 million paid to repurchase ordinary shares;

• $214 million of repayments of long-term debt; and

• $23 million paid for taxes related to net share settlement of equity awards; offset by

• $113 million in proceeds from the issuance of ordinary shares under employee stock plans.

Net cash used in financing activities of $46 million for fiscal year 2017 was primarily attributable to the following activities:

• net proceeds of $1.2 billion received from issuance of $750 million of 4.25% Senior Notes due 2022 and $500 million of 4.875% Senior Notes due 2024;

• $86 million in proceeds from the issuance of ordinary shares under employee stock plans; offset by

• $561 million in dividend payments;

• $460 million paid to repurchase ordinary shares;

• $316 million of redemption and repurchase of long-term debt; and

• $27 million paid for taxes related to net share settlement of equity awards.

Seagate Technology public limited company | 2018 Form 10-K | 49

Net cash used in financing activities of $1.8 billion for fiscal year 2016 was primarily attributable to the following activities:

• $1.1 billion paid to repurchase ordinary shares; and

• $0.7 billion in dividend payments.

Liquidity Sources

Our primary sources of liquidity as of June 29, 2018, consisted of: (1) approximately $1.9 billion in cash and cash equivalents, (2) cash we expect to generate from operations and (3) a $700 million senior revolving credit facility.

As of June 29, 2018, no borrowings had been drawn under the revolving credit facility or had been utilized for letters of credit issued under this credit facility. The line of credit is available for borrowings, subject to compliance with financial covenants and other customary conditions to borrowing.

The credit agreement that governs our revolving credit facility, as amended, includes three financial covenants: (1) minimum cash, cash equivalents and marketable securities, (2) a fixed charge coverage ratio and (3) a net leverage ratio. On April 28, 2016, the Revolving Credit Agreement was amended in order to increase the allowable net leverage ratio to adjust for our financial liquidity position. The term of the revolving credit facility is through January 15, 2020 provided that if we do not have Investment Grade Ratings (as defined in the revolving credit facility) on August 15, 2018, then the maturity date will be August 16, 2018 unless certain extension conditions have been satisfied. We were in compliance with the modified covenants as of June 29, 2018 and expect to be in compliance for the next 12 months.

As of June 29, 2018, cash and cash equivalents held by non-Irish subsidiaries was $1.8 billion. This amount is potentially subject to taxation in Ireland upon repatriation by means of a dividend into our Irish parent. However, it is our intent to indefinitely reinvest earnings of non-Irish subsidiaries outside of Ireland and our current plans do not demonstrate a need to repatriate such earnings by means of a taxable Irish dividend. Should funds be needed in the Irish parent company and should we be unable to fund parent company activities through means other than a taxable Irish dividend, we would be required to accrue and pay Irish taxes on such dividend.

We believe that our sources of cash will be sufficient to fund our operations and meet our cash requirements for at least the next 12 months.

Cash Requirements and Commitments

Our liquidity requirements are primarily to meet our working capital, product development and capital expenditure needs, to fund scheduled payments of principal and interest on our indebtedness, and to fund our quarterly dividend and any future strategic investments. Our ability to fund these requirements will depend on our future cash flows, which are determined by future operating performance, and therefore, subject to prevailing global macroeconomic conditions and financial, business and other factors, some of which are beyond our control.

On July 30, 2018, our Board of Directors declared a quarterly cash dividend of $0.63 per share, which will be payable on October 3, 2018 to shareholders of record as of the close of business on September 19, 2018.

As of June 29, 2018, we were in compliance with all of the covenants under our debt agreements. Based on our current outlook, we expect to be in compliance with the covenants of our debt agreements over the next 12 months.

Seagate Technology public limited company | 2018 Form 10-K | 50

The carrying value of our debt as of June 29, 2018 and June 30, 2017 was $4.8 billion and $5.0 billion, respectively. The table below presents the principal amounts of our outstanding debt:

From time to time, we may repurchase any of our outstanding ordinary shares through private, open market, tender offers, broker assisted purchases or other means. During fiscal year 2018, we repurchased approximately 11 million of our ordinary shares including statutory tax withholdings related to vesting of employee equity awards. See “Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities-Repurchases of Our Equity Securities.” As of June 29, 2018, $0.9 billion remained available for repurchase under our existing repurchase authorization limit. All repurchases are effected as redemptions in accordance with our Articles of Association.

For fiscal year 2019, we expect capital expenditures to remain below our long-term targeted range of 6% to 8% of revenue. We require substantial amounts of cash to fund any increased working capital requirements, future capital expenditures, scheduled payments of principal and interest on our indebtedness and payments of dividends. We will continue to evaluate and manage the retirement and replacement of existing debt and associated obligations, including evaluating the issuance of new debt securities, exchanging existing debt securities for other debt securities and retiring debt pursuant to privately negotiated transactions, open market purchases, tender offers or other means or otherwise. In addition, we may selectively pursue strategic alliances, acquisitions, joint ventures and investments, which may require additional capital.

Seagate Technology public limited company | 2018 Form 10-K | 51

As of June 29, 2018, we had a liability for unrecognized tax benefits and an accrual for the payment of related interest totaling $62 million, none of which is expected to be settled within one year. Outside of one year, we are unable to make a reasonably reliable estimate of when cash settlement with a taxing authority will occur.

Off-Balance Sheet Arrangements

As of June 29, 2018, we did not have any material off-balance sheet arrangements (as defined in Item 303(a)(4)(ii) of Regulation S-K).

Accounting Policies

The methods, estimates and judgments we use in applying our most critical accounting policies have a significant impact on the results we report in our consolidated financial statements. The SEC has defined the most critical accounting policies as the ones that are most important to the portrayal of our financial condition and operating results, and require us to make our most difficult and subjective judgments, often as a result of the need to make estimates of matters that are highly uncertain at the time of estimation. Based on this definition, our most critical accounting policies include: establishment of sales program accruals, establishment of warranty accruals, accounting for income taxes, the impairment assessment for goodwill and other long-lived assets and investment in debt security. Below, we discuss these policies further, as well as the estimates and judgments involved. We also have other accounting policies and accounting estimates relating to uncollectible customer accounts, valuation of inventory, valuation of share-based payments and restructuring. We believe that these other accounting policies and accounting estimates either do not generally require us to make estimates and judgments that are as difficult or as subjective, or it is less likely that they would have a material impact on our reported results of operations for a given period.

Establishment of Sales Program Accruals. We establish certain distributor and OEM sales programs aimed at increasing customer demand. For OEM sales, rebates are typically based on an OEM customer’s volume of purchases or other agreed upon rebate programs. For the distribution channel, these programs typically involve rebates related to a distributor’s level of sales, order size, advertising or point of sale activity and price protection adjustments. We provide for these obligations at the time that revenue is recorded based on estimated requirements. We estimate these contra-revenue rebates and adjustments based on various factors, including price reductions during the period reported, estimated future price erosion, customer orders, distributor sell-through and inventory levels, program participation, customer claim submittals and sales returns. Our estimates reflect contractual arrangements but also our judgment relating to variables such as customer claim rates and attainment of program goals, and inventory and sell-through levels reported by our distribution customers. Currently, our distributors’ inventories are within the historical range.

While we believe we have sufficient experience and knowledge of the market and customer buying patterns to reasonably estimate such rebates and adjustments, actual market conditions or customer behavior could differ from our expectations. As a result, actual payments under these programs, which may spread over several months after the related sale, may vary from the amount accrued. Accordingly, revenues and margins in the period in which the adjustment occurs may be affected.

Significant actual variations in any of the factors upon which we base our contra-revenue estimates could have a material effect on our operating results. In fiscal year 2018, sales programs were approximately 12% of gross revenue. For fiscal years 2017 and 2016, total sales programs of gross revenues were 11% and 13%, respectively. Adjustments to revenues due to under or over accruals for sales programs related to revenues reported in prior quarterly periods were less than 1% of gross revenue in fiscal years 2018, 2017 and 2016. Any future shifts in the industry supply-demand balance as well as other factors may result in a more competitive pricing environment and may cause sales programs as a percentage of gross revenue to increase from the current or historical levels. If such rebates and incentives trend upwards, revenues and margins may be reduced.

Establishment of Warranty Accruals. We estimate probable product warranty costs at the time revenue is recognized. We generally warrant our products for a period of 1 to 5 years. Our warranty provision considers estimated product failure rates and trends (including the timing of product returns during the warranty periods), and estimated repair or replacement costs related to product quality issues, if any. We also exercise judgment in estimating our ability to sell certain repaired products. Should actual experience in any future period differ significantly from our estimates, our future results of operations could be materially affected. Our judgment is subject to a greater degree of subjectivity with respect to newly introduced products because of limited experience with those products upon which to base our warranty estimates.

Seagate Technology public limited company | 2018 Form 10-K | 52

The actual results with regard to warranty expenditures could have an adverse or favorable effect on our results of operations if the actual rate of unit failure, the cost to repair a unit, or the actual cost required to satisfy customer claims differs from those estimates we used in determining the warranty accrual. Since we typically outsource our warranty repairs, our repair cost is subject to periodic negotiations with vendors and may vary from our estimates. To the extent such sales fall below our forecast, warranty cost will be adversely impacted.

We review our warranty accrual quarterly for products shipped in prior periods and which are still under warranty. Any changes in the estimates underlying the accrual may result in adjustments that impact the current period gross margins and net income. In fiscal years 2018, 2017 and 2016 net changes in estimates of prior warranty accruals as a percentage of revenue were immaterial. Our total warranty cost was 1.0%, 1.3% and 1.0% of revenue during fiscal years 2018, 2017 and 2016, respectively, while warranty cost related to new shipments (exclusive of the impact of re-estimates of pre-existing liabilities) were 1.3%, 1.2% and 1.1% respectively, for the same periods. Changes in anticipated failure rates of specific products and significant changes in repair or replacement costs have historically been the major reasons for significant changes in prior estimates. Any future changes in failure rates of certain products, as well as changes in repair costs or the cost of replacement parts, may result in increased or decreased warranty accruals.

Accounting for Income Taxes. We account for income taxes pursuant to Accounting Standards Codification (“ASC”) Topic 740 (“ASC 740”), Income Taxes. In applying ASC 740, we make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of tax credits, recognition of income and deductions and calculation of specific tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for income tax and financial statement purposes, as well as tax liabilities associated with uncertain tax positions. The calculation of tax liabilities involves uncertainties in the application of complex tax rules and the potential for future adjustment of our uncertain tax positions by the Internal Revenue Service or other tax jurisdictions. If estimates of these tax liabilities are greater or less than actual results, an additional tax benefit or provision will result. The deferred tax assets we record each period depend primarily on our ability to generate future taxable income in the United States and certain non-U.S. jurisdictions. Each period, we evaluate the need for a valuation allowance for our deferred tax assets and, if necessary, we adjust the valuation allowance so that net deferred tax assets are recorded only to the extent we conclude it is more likely than not that these deferred tax assets will be realized. If our outlook for future taxable income changes significantly, our assessment of the need for a valuation allowance may also change.

Assessing Goodwill and Other Long-lived Assets for Impairment. We account for goodwill in accordance with ASC Topic 350, Intangibles — Goodwill and Other. As permitted by ASC 350, we perform a qualitative assessment in the fourth quarter of each year, or more frequently if indicators of potential impairment exist, to determine if any events or circumstances exist, such as an adverse change in business climate or a decline in the overall industry that would indicate that it would more likely than not reduce the fair value of a reporting unit below its carrying amount. Based on the qualitative assessment, if it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then the Company is not required to perform the quantitative goodwill impairment test. If it is determined in the qualitative assessment that the fair value of a reporting unit is more likely than not below its carrying amount, including goodwill, then we perform a quantitative impairment test. The quantitative goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. Any excess in the carrying value of a reporting unit’s goodwill over its fair value is recognized as an impairment loss, limited to the total amount of goodwill allocated to that reporting unit.

In accordance with ASC 360-05-4, Impairment or Disposal of Long-lived Assets, we test other long-lived assets, including property, equipment and leasehold improvements and other intangible assets subject to amortization, for recoverability whenever events or changes in circumstances indicate that the carrying values of those assets may not be recoverable. We assess the recoverability of an asset group by determining if the carrying value of the asset group exceeds the sum of the projected undiscounted cash flows expected to result from the use and eventual disposition of the assets over the remaining economic life of the primary asset in the asset group. If the recoverability test indicates that the carrying value of the asset group is not recoverable, we will estimate the fair value of the asset group and compare it to its carrying value. The excess of the carrying value over the fair value is allocated pro rata to derive the adjusted carrying value of each asset in the asset group. The adjusted carrying value of each asset in the asset group is not reduced below its fair value.

Seagate Technology public limited company | 2018 Form 10-K | 53

Assessing Investment in Debt Security for Impairment. Our investment in non-convertible preferred stock of K.K. Pangea, for which we have the positive intent and ability to hold until maturity is carried at the amortized cost and classified as a held-to-maturity debt security. We assess whether an other-than-temporary impairment loss on the investment, including the accrued payment-in-kind (“PIK”) income, has occurred due to a decline in fair value or other market conditions. If the fair value of the security is below amortized cost and it is more likely than not that we will not be able to recover its amortized cost bases before its stated maturity, we will record an other-than-temporary impairment charge to Other, net in the Consolidated Statements of Operations.

Recent Accounting Pronouncements

See “Item 8. Financial Statements and Supplementary Data — Note 1. Basis of Presentation and Summary of Significant Accounting Policies” for information regarding the effect of new accounting pronouncements on our financial statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We have exposure to market risks due to the volatility of interest rates, foreign currency exchange rates, credit rating changes, equity and bond markets. A portion of these risks may be hedged, but fluctuations could impact our results of operations, financial position and cash flows.

Interest Rate Risk. Our exposure to market risk for changes in interest rates relates primarily to our cash investment portfolio including investment in debt security in Pangea. As of June 29, 2018, we had no available-for-sale securities that had been in a continuous unrealized loss position for a period greater than 12 months. We determined no available-for-sale securities were other-than-temporarily impaired as of June 29, 2018.

We have fixed rate debt obligations. We enter into debt obligations for general corporate purposes including capital expenditures and working capital needs.

The table below presents principal amounts and related fixed or weighted-average interest rates by year of maturity for our investment portfolio and debt obligations as of June 29, 2018.

Foreign Currency Exchange Risk. From time to time, we may enter into foreign currency forward exchange contracts to manage exposure related to certain foreign currency commitments and anticipated foreign currency denominated expenditures. Our policy prohibits us from entering into derivative financial instruments for speculative or trading purposes. At this time, we have not identified any material exposure associated with the potential changes related to the British vote to exit the European Union.

Seagate Technology public limited company | 2018 Form 10-K | 54

We hedge portions of our foreign currency denominated balance sheet positions with foreign currency forward exchange contracts to reduce the risk that our earnings will be adversely affected by changes in currency exchange rates. We entered into foreign currency forward exchange contracts with an aggregate notional amount of 139.5 billion Japanese Yen ($1.3 billion at June 29, 2018), to hedge foreign exchange fluctuations of our investment principal in non-convertible preferred stock debt security of Pangea. We did not designate these contracts as hedges under ASC 815, Derivatives and Hedging and, therefore, the change in fair value of these contracts is recognized in earnings in the same period as the gains and losses from the remeasurement of the debt security. All these foreign currency forward exchange contracts mature within 12 months.

We evaluate hedging effectiveness prospectively and retrospectively. We entered into a foreign currency forward exchange contract with a notional amount of approximate 7 billion Japanese Yen ($66 million at June 29, 2018), to hedge the PIK income related to Pangea investment, which is designated as a cash flow hedge. We evaluate the hedge effectiveness using the critical terms match method pursuant to ASU 2017-12, Derivatives and Hedging, Targeted Improvements to Accounting for Hedging Activities, which we adopted in the June 2018 quarter.

We did not have any material net gains (losses) recognized in Cost of revenue, or Other, net for cash flow hedges due to hedge ineffectiveness or discontinued cash flow hedges during the fiscal years 2018 and 2017.

The table below provides information as of June 29, 2018 about our foreign currency forward exchange contracts. The table is provided in U.S. dollar equivalent amounts and presents the notional amounts (at the contract exchange rates) and the weighted-average contractual foreign currency exchange rates.

(Dollars in millions, except average contract rate)	Notional Amount		Average Contract Rate		Estimated Fair Value(1)
Foreign currency forward exchange contracts:
Japanese Yen	$	1,376	$	106.50	$	10
Total	$	1,376			$	10

⁽¹⁾  Equivalent to the unrealized net gain (loss) on existing contracts.

We did not have outstanding foreign currency forward exchange contracts as of June 30, 2017.

Other Market Risks. We have exposure to counterparty credit downgrades in the form of credit risk related to our foreign currency forward exchange contracts and our fixed income portfolio. We monitor and limit our credit exposure for our foreign currency forward exchange contracts by performing ongoing credit evaluations. We also manage the notional amount of contracts entered into with any one counterparty, and we maintain limits on maximum tenor of contracts based on the credit rating of the financial institution. Additionally, the investment portfolio is diversified and structured to minimize credit risk.

Changes in our corporate issuer credit ratings have minimal impact on our near term financial results, but downgrades may negatively impact our future ability to raise capital, increase the cost of such capital and our ability to execute transactions with various counterparties.

We have an investment in debt security of $1.3 billion carried at amortized cost. We review our debt security for impairment when events and circumstances indicate a decline in fair value of such asset below carrying value is other-than-temporary.

We are subject to equity market risks due to changes in the fair value of the notional investments selected by our employees as part of our Non-qualified Deferred Compensation Plan—the Seagate Deferred Compensation Plan (the “SDCP”). In fiscal year 2014, we entered into a Total Return Swap (“TRS”) in order to manage the equity market risks associated with the SDCP liabilities. We pay a floating rate, based on LIBOR plus an interest rate spread, on the notional amount of the TRS. The TRS is designed to substantially offset changes in the SDCP liability due to changes in the value of the investment options made by employees. See “Item 8. Financial Statements and Supplementary Data—Note 8. Derivative Financial Instruments” of this Report on Form 10-K.

SEAGATE TECHNOLOGY PLC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of Presentation and Summary of Significant Accounting Policies

Organization

Seagate Technology plc (the “Company”) is a leading provider of data storage technology and solutions. Its principal products are hard disk drives, commonly referred to as disk drives, hard drives or HDDs. In addition to HDDs, the Company produces a broad range of data storage products including solid state drives (“SSDs”), solid state hybrid drives (“SSHDs”) and storage subsystems.

Hard disk drives are devices that store digitally encoded data on rapidly rotating disks with magnetic surfaces. Disk drives continue to be the primary medium of mass data storage due to their performance attributes, high quality and cost effectiveness. Complementing existing data center storage architecture, solid-state storage devices use integrated circuit assemblies as memory to store data, and most SSDs use NAND flash memory. In addition to HDDs and SSDs, SSHDs combine the features of SSDs and HDDs in the same unit, containing a high capacity hard disk drive and a smaller SSD acting as a cache to improve performance of frequently accessed data.

The Company’s HDD products are designed for mission critical and nearline applications in enterprise servers and storage systems; edge compute/client compute applications, where its products are designed primarily for desktop and mobile computing; and edge non-compute/client non-compute applications, where its products are designed for a wide variety of end user devices such as portable external storage systems, surveillance systems, digital video recorders (“DVRs”), network-attached storage (“NAS”) and gaming consoles. The Company’s SSD products mainly include serial attached SCSI (“SAS”) and Non-Volatile Memory Express (“NVMe”) SSDs.

The Company’s cloud systems and solutions portfolio includes modular original equipment manufacturer (“OEM”) storage systems and scale-out storage servers.

Basis of Presentation and Consolidation

The consolidated financial statements include the accounts of the Company and all its wholly-owned and majority-owned subsidiaries, after elimination of intercompany transactions and balances.

The preparation of financial statements in accordance with U.S. generally accepted accounting principles also requires management to make estimates and assumptions that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. The methods, estimates and judgments the Company uses in applying its most critical accounting policies have a significant impact on the results the Company reports in its consolidated financial statements. Certain prior years amounts reported in the consolidated financial statements and notes thereto have been reclassified to conform to the current year’s presentation.

The Company operates and reports financial results on a fiscal year of 52 or 53 weeks ending on the Friday closest to June 30. Accordingly, fiscal years 2018, 2017 and 2016 were comprised of 52 weeks ended on June 29, 2018, June 30, 2017 and July 1, 2016, respectively. All references to years in these Notes to Consolidated Financial Statements represent fiscal years unless otherwise noted. Fiscal year 2019 will be comprised of 52 weeks and will end on June 28, 2019.

Summary of Significant Accounting Policies

Cash, Cash Equivalents and Short-Term Investments. The Company considers all highly liquid investments with a remaining maturity of 90 days or less at the time of purchase to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value. From time to time, the Company has short-term investments that are primarily comprised of money market funds, time deposits and certificates of deposits. The Company has classified its marketable securities as available-for-sale and they are stated at fair value with unrealized gains and losses included in Accumulated other comprehensive loss, which is a component of Shareholders’ Equity. The Company evaluates the available-for sale securities in an unrealized loss position for other-than-temporary impairment. Realized gains and losses are included in Other, net on the Company’s Consolidated Statements of Operations. The cost of securities sold is based on the specific identification method.

Seagate Technology public limited company | 2018 Form 10-K | 62

Restricted Cash and Investments. Restricted cash and investments represent cash and cash equivalents and investments that are restricted as to withdrawal or use for other than current operations.

Allowances for Doubtful Accounts. The Company maintains an allowance for uncollectible accounts receivable based upon expected collectability. This reserve is established based upon historical trends, global macroeconomic conditions and an analysis of specific exposures. The provision for doubtful accounts is recorded as a charge to Marketing and administrative expense on the Company’s Consolidated Statements of Operations.

Inventory. The Company accounts for inventory in accordance with Accounting Standard Codification (“ASC”) Topic 330, Inventory. During fiscal year 2018, the Company adopted Accounting Standard Update (“ASU”) No. 2015-11, Inventory: Simplifying the Measurement of Inventory (ASC topic 330). Inventories are valued at the lower of cost (using the first-in, first-out method) and net realizable value. Net realizable value is based upon the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.

Property, Equipment and Leasehold Improvements. Property, equipment and leasehold improvements are stated at cost. Equipment and buildings are depreciated using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated life of the asset or the remaining term of the lease. The costs of additions and substantial improvements to property, equipment and leasehold improvements, which extend the economic life of the underlying assets, are capitalized. The cost of maintenance and repairs to property, equipment and leasehold improvements is expensed as incurred.

Assessment of Goodwill and Other Long-lived Assets for Impairment. The Company accounts for goodwill in accordance with ASC Topic 350 (“ASC 350”), Intangibles—Goodwill and Other. The Company performs a qualitative assessment in the fourth quarter of each year, or more frequently if indicators of potential impairment exist, to determine if any events or circumstances exist, such as an adverse change in business climate or a decline in the overall industry that would indicate that it would more likely than not reduce the fair value of a reporting unit below its carrying amount, including goodwill. If it is determined in the qualitative assessment that the fair value of a reporting unit is more likely than not below its carrying amount, including goodwill, then the Company will perform a quantitative impairment test. The quantitative goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. Any excess in the carrying value of a reporting unit’s goodwill over its fair value is recognized as an impairment loss, limited to the total amount of goodwill allocated to that reporting unit.

The Company tests other long-lived assets, including property, equipment and leasehold improvements and other intangible assets subject to amortization, for recoverability whenever events or changes in circumstances indicate that the carrying value of those assets may not be recoverable. The Company performs a recoverability test to assess the recoverability of an asset group. If the recoverability test indicates that the carrying value of the asset group is not recoverable, the Company will estimate the fair value of the asset group and the excess of the carrying value over the fair value is allocated pro rata to derive the adjusted carrying value of assets in the asset group. The adjusted carrying value of each asset in the asset group is not reduced below its fair value.

The Company tests other intangible assets not subject to amortization whenever events occur or circumstances change, such as declining financial performance, deterioration in the environment in which the entity operates or deteriorating macroeconomic conditions that have a negative effect on future expected earnings and cash flows that could affect significant inputs used to determine the fair value of the indefinite-lived intangible asset.

Investment in Debt Security and Payment-in-Kind (“PIK”) Income. The Company has debt investment in non-convertible preferred stock of K.K. Pangea. The Company determined the appropriate classification of such investment at the time of purchase and will re-evaluate such designation at each balance sheet date. The Company classified the investment as held-to-maturity as it has the positive intent and ability to hold the security until maturity. This held-to-maturity investment is carried at amortized cost and recorded as Investment in debt security on the Consolidated Balance Sheets.

Transaction costs incurred by the Company to acquire this investment are capitalized and amortized as a reduction of interest income on the Consolidated Statements of Operations over the respective term of the investment. The investment contains a PIK income provision, which represents contractual interest that is due at maturity, and is accrued and recorded as Interest income each reporting period and added to the carrying value of the Investment in debt security.

Seagate Technology public limited company | 2018 Form 10-K | 63

The Company assesses whether an other-than-temporary impairment loss on the debt security, including the accrued PIK income, has occurred due to a decline in fair value or other market conditions. If the fair value of the debt security is below amortized cost and it is more likely than not that the Company will not be able to recover the amortized cost bases before its stated maturity, the Company will record an other-than-temporary impairment charge to Other, net in the Consolidated Statements of Operations.

Derivative Financial Instruments. The Company applies the requirements of ASC Topic 815 (“ASC 815”), Derivatives and Hedging. ASC 815 requires that all derivatives be recorded on the balance sheet at fair value and establishes criteria for designation and effectiveness of hedging relationships. During fiscal year 2018, the Company early adopted ASU No. 2017-12, Derivatives and Hedging (ASC Topic 815) — Targeted Improvements to Accounting for Hedging Activities. The Company continues to exclude the change in forward points from the assessment of hedge effectiveness and recognizes the excluded component in Other, net in the Consolidated Statements of Operations. Foreign currency forward exchange contracts not designated as hedge instruments are used to economically hedge the foreign currency exposure in the value of an investment denominated in currency other than U.S. dollar. The Company recognizes the unrealized gains (losses) due to the changes in the fair value of these contracts in Other, net in the Consolidated Statements of Operations along with the foreign currency gains and losses on remeasurement of such investment.

Establishment of Warranty Accruals. The Company estimates probable product warranty costs at the time revenue is recognized. The Company generally warrants its products for a period of 1 to 5 years. The Company’s warranty provision considers estimated product failure rates and trends (including the timing of product returns during the warranty periods), and estimated repair or replacement costs related to product quality issues, if any. The Company also exercises judgment in estimating its ability to sell certain repaired products. Should actual experience in any future period differ significantly from its estimates, the Company’s future results of operations could be materially affected.

Revenue Recognition, Sales Returns and Allowances, and Sales Incentive Programs. The Company’s revenue recognition policy complies with ASC Topic 605 (“ASC 605”), Revenue Recognition. Revenue from sales of products, including sales to distribution customers, is generally recognized when title and risk of loss has passed to the buyer, which typically occurs upon shipment from the Company or third party’s warehouse facilities, persuasive evidence of an arrangement exists, including a fixed or determinable price to the buyer, and when collectability is reasonably assured. Revenue from sales of products to certain direct retail customers and to customers in certain indirect retail channels is recognized on a sell-through basis.

The Company records estimated product returns at the time of shipment. The Company also estimates reductions to revenue for sales incentive programs, such as price protection, and volume incentives, and records such reductions when revenue is recorded. The Company establishes certain distributor and OEM sales programs aimed at increasing customer demand. For OEM sales, rebates are typically based on an OEM customer’s volume of purchases from Seagate or other agreed upon rebate programs. For the distribution channel, these programs typically involve rebates related to a distributor’s level of sales, order size, advertising or point of sale activity and price protection adjustments. The Company provides for these obligations at the time that revenue is recorded based on estimated requirements. Marketing development programs are recorded as a reduction to revenue.

Shipping and Handling. The Company includes costs related to shipping and handling in Cost of revenue in the Consolidated Statements of Operations for all periods presented.

Restructuring Costs. The Company records restructuring activities including costs for one-time termination benefits in accordance with ASC Topic 420 (“ASC 420”), Exit or Disposal Cost Obligations. The timing of recognition for severance costs accounted for under ASC 420 depends on whether employees are required to render service until they are terminated in order to receive the termination benefits. If employees are required to render service until they are terminated in order to receive the termination benefits, a liability is recognized ratably over the future service period. Otherwise, a liability is recognized when management has committed to a restructuring plan and has communicated those actions to employees. Employee termination benefits covered by existing benefit arrangements are recorded in accordance with ASC Topic 712, Nonretirement Postemployment Benefits. These costs are recognized when management has committed to a restructuring plan and the severance costs are probable and estimable.

Seagate Technology public limited company | 2018 Form 10-K | 64

Advertising Expense. The cost of advertising is expensed as incurred. Advertising costs were approximately $28 million, $16 million and $31 million in fiscal years 2018, 2017 and 2016, respectively.

Share-Based Compensation. The Company accounts for share-based compensation under the provisions of ASC Topic 718 (ASC 718), Compensation-Stock Compensation. During fiscal year 2018, the Company adopted ASU 2016-09, Stock Compensation—Improvements to Employee Share-Based Payment Accounting (ASC Topic 718). The Company has elected to apply the with-and-without method to assess the realization of related excess tax benefits. The Company also elected to continue to account for share-based compensation expense net of estimated forfeitures.

Accounting for Income Taxes. The Company accounts for income taxes pursuant to ASC Topic 740 (“ASC 740”), Income Taxes. During fiscal year 2018, the Company adopted ASU 2016-16, Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory (ASC Topic 740). In applying ASC 740, the Company makes certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of tax credits, recognition of income and deductions and calculation of specific tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for income tax and financial statement purposes, as well as tax liabilities associated with uncertain tax positions. The calculation of tax liabilities involves uncertainties in the application of complex tax rules and the potential for future adjustment of the Company’s uncertain tax positions by the Internal Revenue Service or other tax jurisdictions. If estimates of these tax liabilities are greater or less than actual results, an additional tax benefit or provision will result. The deferred tax assets the Company records each period depend primarily on the Company’s ability to generate future taxable income in the United States and certain non-U.S. jurisdictions. Each period, the Company evaluates the need for a valuation allowance for its deferred tax assets and, if necessary, adjusts the valuation allowance so that net deferred tax assets are recorded only to the extent the Company concludes it is more likely than not that these deferred tax assets will be realized. If the Company’s outlook for future taxable income changes significantly, the Company’s assessment of the need for, and the amount of, a valuation allowance may also change.

Comprehensive Income. The Company presents comprehensive income in a separate statement. Comprehensive income is comprised of net income and other gains and losses affecting equity that are excluded from net income.

Foreign Currency Remeasurement and Translation. The U.S. dollar is the functional currency for the majority of the Company’s foreign operations. Monetary assets and liabilities denominated in foreign currencies are remeasured into the functional currency of the subsidiary at the balance sheet date. The gains and losses from the remeasurement of foreign currency denominated balances into the functional currency of the subsidiary are included in Other, net on the Company’s Consolidated Statements of Operations. The Company’s subsidiaries that use the U.S. dollar as their functional currency remeasure monetary assets and liabilities at exchange rates in effect at the end of each period, and nonmonetary assets and liabilities at historical rates.

The Company had $3 million, $9 million and $3 million in remeasurement losses in fiscal years 2018, 2017 and 2016, respectively.

The Company translates the assets and liabilities of its non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period. Revenue and expenses for these subsidiaries are translated using rates that approximate those in effect during the period. Gains and losses from these translations are recognized in foreign currency translation included in Accumulated other comprehensive loss, which is a component of shareholders’ equity.

Concentrations

Concentration of Credit Risk. The Company’s customer base for disk drive products is concentrated with a small number of customers. The Company does not generally require collateral or other security to support accounts receivable. To reduce credit risk, the Company performs ongoing credit evaluations on its customers’ financial condition. The Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of customers, historical trends and other information. Dell Inc. accounted for more than 10% of the Company’s accounts receivable as of June 29, 2018 and June 30, 2017.

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents, investments and foreign currency forward exchange contracts. The Company mitigates concentrations of credit risk in its investments through diversifications, by investing in highly-rated securities or major multinational companies.

Seagate Technology public limited company | 2018 Form 10-K | 65

In entering into foreign currency forward exchange contracts, the Company assumes the risk that might arise from the possible inability of counterparties to meet the terms of their contracts. The counterparties to these contracts are major multinational commercial banks, and the Company has not incurred and does not expect any losses as a result of counterparty defaults.

Supplier Concentration. Certain of the raw materials, components and equipment used by the Company in the manufacture of its products are available from single-sourced vendors. Shortages could occur in these essential materials and components due to an interruption of supply or increased demand in the industry. If the Company were unable to procure certain materials, components or equipment at acceptable prices, it would be required to reduce its manufacturing operations, which could have a material adverse effect on its results of operations. In addition, the Company may make prepayments to certain suppliers or enter into minimum volume commitment agreements. Should these suppliers be unable to deliver on their obligations or experience financial difficulty, the Company may not be able to recover these prepayments.

Recently Issued Accounting Pronouncements

In May 2014, August 2015, April 2016, May 2016 and December 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09 (ASC Topic 606), Revenue from Contracts with Customers, ASU 2015-14 (ASC Topic 606) Revenue from Contracts with Customers, Deferral of the Effective Date, ASU 2016-10 (ASC Topic 606) Revenue from Contracts with Customers, Identifying Performance Obligations and Licensing, ASU 2016-12 (ASC Topic 606) Revenue from Contracts with Customers, Narrow-Scope Improvements and Practical Expedients, and ASU 2016-20 (ASC Topic 606) Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, respectively. ASC Topic 606 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. It also requires entities to disclose both quantitative and qualitative information that enable financial statements users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company is required to adopt the guidance in the first quarter of fiscal year 2019. This standard may be applied retrospectively to all prior periods presented, or retrospectively with a cumulative adjustment to retained earnings in the year of adoption (“modified retrospective transition approach”). The Company will adopt this standard in the first quarter of fiscal year 2019 utilizing the modified retrospective transition approach.

The Company has substantially completed its evaluation and expects the adoption of the new standard will result in the recognition of revenue when the products are delivered (sell-in basis) to certain direct retail customers and customers in certain indirect retail channels which are currently being recognized on a sell-through basis. Accordingly, the Company will estimate appropriate accruals for the variable consideration (e.g. rebates) related to customer incentives on these arrangements. On the date of initial adoption, the Company will remove the deferred income that would have been subsequently recognized on a sell-through basis and record estimates of the accruals for variable consideration through a cumulative adjustment to accumulated deficit. The Company believes that these changes will not have a material impact on the Company’s consolidated financial statements and internal controls over financial reporting.

In January 2016, the FASB issued ASU 2016-01 (ASC Subtopic 825-10), Financial Instruments—Overall Recognition and Measurement of Financial Assets and Financial Liabilities, as amended by ASU 2018-03, Financial Instruments—Overall: Technical Correction and Improvements, issued in February 2018. The amendments in these ASUs require entities to measure all investments in equity securities at fair value with changes recognized through net income. This requirement does not apply to investments that qualify for the equity method of accounting, to those that result in consolidation of the investee, or for which the entity meets a practicability exception to fair value measurement. Additionally, the amendments eliminate certain disclosure requirements related to financial instruments measured at amortized cost and add disclosures related to the measurement categories of financial assets and financial liabilities. The Company is required to adopt the guidance in the first quarter of fiscal year 2019. Early adoption is permitted for only certain portions of the ASU. The Company expects to elect the measurement alternative for measurement of equity investments, defined as cost, less impairments, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment in the same issuer (the “Price Changes”) until the equity investments’ fair value becomes readily determinable. The amount of the impact to equity investments will depend on any Price Changes observed after adoption in the first quarter of fiscal year 2019.

In February 2016 and July 2018, the FASB issued ASU 2016-02 (ASC Topic 842), Leases, ASU 2018-10, Codification Improvements to Topic 842, Leases, ASU 2018-11, Leases (ASC Topic 842), Targeted Improvements, respectively. ASC Topic 842 amends a number of aspects of lease accounting, including requiring lessees to recognize operating leases with a term greater than one year on their balance sheet as a right-of-use asset and corresponding lease liability, measured at the present value of the lease payments. The Company is required to adopt this guidance in the first quarter of fiscal year 2020. Early adoption is permitted. The Company is in the process of assessing the impact of these ASUs on its consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13 (ASC Topic 326), Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments. This ASU amends the requirement on the measurement and recognition of expected credit losses for financial assets held. The Company is required to adopt this guidance in the first quarter of fiscal year 2021. Early adoption in the first quarter of fiscal year 2020 is permitted. The Company is in the process of assessing the impact of this ASU on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01 (ASC Topic 805), Business Combinations: Clarifying the Definition of a Business. The amendments in this ASU change the definition of a business to assist with evaluating when a set of transferred assets and activities is a business. The Company plans to adopt the guidance in the first quarter of fiscal year 2019. The Company does not expect the adoption of this ASU will have a material impact on its consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09 (ASC Topic 718), Stock Compensation: Scope of Modification Accounting. The amendments in this ASU provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The Company plans to adopt the guidance in the first quarter of fiscal year 2019. The Company does not expect the adoption of this ASU will have a material impact on its consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02 (ASC Topic 220), Income Statement—Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU was issued following the enactment of the U.S. Tax Cuts and Jobs Act of 2017 (the “Tax Act”) and permits entities to elect a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. The Company is required to adopt the guidance in the first quarter of fiscal year 2020. Early adoption is permitted. The Company is in the process of assessing the impact of this ASU on its consolidated financial statements.

Recently Adopted Accounting Pronouncements

In July 2015, the FASB issued ASU 2015-11 (ASC Topic 330), Inventory: Simplifying the Measurement of Inventory. The amendments in this ASU require inventory measurement at the lower of cost and net realizable value. This ASU became effective and was adopted by the Company in the September 2017 quarter on a prospective basis. The adoption of this guidance had no material impact on the Company’s consolidated financial statements and disclosures.

In March 2016, the FASB issued ASU 2016-09 (ASC Topic 718), Stock Compensation—Improvements to Employee Share-Based Payment Accounting. The amendments in this ASU are intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax consequences, classification on the consolidated statement of cash flows and treatment of forfeitures. This ASU became effective and was prospectively adopted by the Company in the September 2017 quarter. Upon adoption, excess tax benefits or deficiencies from share-based award activity are reflected in the Consolidated Statements of Operations as a component of the provision for income taxes, whereas they previously were recognized in the Shareholders’ equity in the Consolidated Balance Sheets. The Company also elected to continue to account for share-based compensation expense net of estimated forfeitures. The adoption of this ASU resulted in an increase in deferred tax assets relating to net operating losses of approximately $0.6 billion, offset by an equivalent increase in the valuation allowance with no impact to retained earnings. The adoption of this guidance had no material impact on the Company’s consolidated financial statements and disclosures.

Seagate Technology public limited company | 2018 Form 10-K | 67

In October 2016, the FASB issued ASU 2016-16 (ASC Topic 740), Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory.

In August 2017, the FASB issued ASU 2017-12 (ASC Topic 815), Derivatives and Hedging, Targeted Improvements to Accounting for Hedging Activities. The amendments in this ASU simplify the application of hedge accounting guidance and more closely aligning financial reporting for hedging relationships with economic results of an entity’s risk management activities. The Company early adopted this ASU in the June 2018 quarter. The adoption of this guidance had no material impact on the Company’s consolidated financial statements and disclosures.

Depreciation expense, which includes amortization of leasehold improvements, was $487 million, $581 million and $641 million for fiscal years 2018, 2017 and 2016, respectively. Interest on borrowings related to eligible capital expenditures is capitalized as part of the cost of the qualified assets and amortized over the estimated useful lives of the assets. During fiscal years 2018, 2017 and 2016, the Company capitalized interest of $1 million, $4 million and $13 million, respectively.

In fiscal years 2017 and 2016, the Company determined it would discontinue the use of certain manufacturing property and equipment in the short-term, and that certain other buildings, land and manufacturing property and equipment were permanently impaired. As a result, the Company recognized charges of $72 million and $53 million in fiscal years 2017 and 2016, respectively, from the write-off and accelerated depreciation of these fixed assets, including $35 million impairment on land and buildings in fiscal year 2017, classified as held for sale under Other current assets in the Consolidated Balance Sheet. Please refer to Note 9. Fair Value for more details.

Consolidated Statement of Operations. In fiscal year 2018, the Company recognized a charge of $7 million from the write-off and accelerated depreciation of certain fixed assets, of which $1 million, $4 million and $2 million was recorded to Cost of revenue, Product development and Marketing and administrative, respectively, in the Consolidated Statement of Operations.

Investment in Debt Security

On May 31, 2018, the Company invested approximately $1.3 billion in non-convertible preferred stock of K.K. Pangea for the acquisition of Toshiba Memory Corporation with a consortium of investors led by Bain Capital Private Equity. The investment, with a contractual maturity of six years, is accounted for as a held-to-maturity debt security, carried at cost and adjusted for amortization of transaction costs into interest income. Additionally, the debt security has a contractual PIK income which will be paid in cash upon redemption of the investment. PIK income computed at the contractual rate is accrued into Interest income in the Consolidated Statement of Operations and added to the carrying value of the Investment in debt security on the Consolidated Balance Sheet. In fiscal year 2018, the PIK income earned was $5 million. As of June 29, 2018, no impairment was identified and the fair value of the investment was determined to approximate its carrying value at amortized cost.

Short-Term Borrowings

The credit agreement entered into by the Company and its subsidiary Seagate HDD Cayman on January 18, 2011 and subsequently amended (the “Revolving Credit Facility”) provides the Company with a $700 million senior secured revolving credit facility. The term of the Revolving Credit Facility is through January 15, 2020, provided that if the Company does not have Investment Grade Ratings (as defined in the Revolving Credit Facility) on August 15, 2018, then the maturity date will be August 16, 2018 unless certain extension conditions have been satisfied. The loans made under the Revolving Credit Facility will bear interest at a rate of LIBOR plus a variable margin that will be determined based on the corporate credit rating of the Company. The Company and certain of its material subsidiaries fully and unconditionally guarantee the Revolving Credit Facility. The Revolving Credit Facility is available for cash borrowings, subject to compliance with certain covenants and other customary conditions to borrowing, and for the issuance of letters of credit up to a sub-limit of $75 million.

The Revolving Credit Facility, as amended, includes three financial covenants: (1) minimum cash, cash equivalents and marketable securities, (2) a fixed charge coverage ratio. and (3) a net leverage ratio. On April 27, 2016, the Revolving Credit

Agreement was amended in order to increase the allowable net leverage ratio to allow for higher net leverage levels. The Company was in compliance with the modified covenants as of June 29, 2018 and expects to be in compliance for the next 12 months.

As of June 29, 2018, no borrowings had been drawn or letters of credit utilized under the Revolving Credit Facility.

Income (loss) before income taxes consisted of the following:

On December 22, 2017, the Tax Act was enacted into law in the United States. The Tax Act significantly revises U.S. corporate income tax law by, among other things, lowering U.S. corporate income tax rates from 35% to 21%, implementing a territorial tax system, and imposing a one-time transition tax on deemed repatriated earnings of non-U.S. subsidiaries.

Pursuant to SEC Staff Accounting Bulletin (“SAB”) 118 (regarding the application of ASC 740 associated with the enactment of the Tax Act), the Company recorded an adjusted tax expense of approximately $204 million during fiscal year 2018, to re-measure its net U.S. deferred tax assets at the newly enacted 21% income tax rate. This tax expense increased the Company’s effective tax rate by approximately 14%. The Company also does not expect the one-time transition tax to have a material impact on the Company’s consolidated financial statements due to an overall accumulated earnings deficit in its non-U.S. subsidiaries for which the transition tax applies. The Company has considered SAB 118 and believes the accounting under ASC 740 for the change to the U.S. statutory tax rate to its deferred tax balances and the one-time transition tax under the Tax Act is complete and appropriately reflected in the financial statements during fiscal year 2018.

For all other provisions relating to the Tax Act, the Company continues to evaluate the impact of the Tax Act’s various highly complex domestic and international provisions. The other U.S. tax changes, including limitations on various business deductions such as executive compensation under Internal Revenue Code §162(m), are not expected to impact the Company’s tax expense in the short-term due to the Company’s large net operating loss and tax credit carryovers and associated valuation allowance. The Tax Act’s new international rules, including Global Intangible Low-Taxed Income (“GILTI”), Foreign Derived Intangible Income (“FDII”), and Base Erosion Anti-Avoidance Tax (“BEAT”) are generally effective in tax years beginning after December 31, 2017. These provisions are not expected to have a material impact on the Company’s

Seagate Technology public limited company | 2018 Form 10-K | 79

consolidated financial statements. However, these preliminary assessments and analyses are provisional and are subject to change as additional interpretive guidance is issued. The Company will complete its analysis within fiscal year 2019 which is consistent with the guidance provided in SAB 118.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company recorded an adjustment for its U.S. deferred income taxes as of June 29, 2018 to reflect the reduction in the U.S. statutory tax rate from 35% to 21% resulting from the Tax Act. The significant components of the Company’s deferred tax assets and liabilities were as follows:

(Dollars in millions)	Fiscal Years Ended

During fiscal year 2018, the Company adopted two accounting pronouncements with tax implications—ASU 2016-09 (related to employee share-based payment accounting) and ASU 2016-16 (related to intra-entity transfers of assets). There was no material impact to the Company’s financial statements as a result of the adoptions. The adoption of ASU 2016-09 resulted in an increase in gross deferred tax assets relating to net operating losses of approximately $0.6 billion offset by an equivalent increase in valuation allowance. For additional detail about both ASU’s, please refer to Note 1. Basis of Presentation and Summary of Significant Accounting Policies.

Seagate Technology public limited company | 2018 Form 10-K | 80

The deferred tax asset valuation allowance increased by $255 million in fiscal year 2018, mainly due to the adoption of ASC 2016-09 offset by the U.S. corporate tax rate reduction as a result of the Tax Act, and decreased by $18 million in fiscal year 2017.

At June 29, 2018, the Company recorded $410 million of net deferred tax assets. The realization of most of these deferred tax assets is primarily dependent on the Company’s ability to generate sufficient U.S. and certain non-U.S. taxable income in future periods. Although realization is not assured, the Company’s management believes it is more likely than not that these deferred tax assets will be realized. The amount of deferred tax assets considered realizable, however, may increase or decrease in subsequent periods when the Company re-evaluates the underlying basis for its estimates of future U.S. and certain non-U.S. taxable income.

At June 29, 2018, the Company had U.S. federal, state and non-U.S. tax net operating loss carryforwards of approximately $3.2 billion, $1.8 billion and $54 million, respectively, which will expire at various dates beginning in fiscal year 2019, if not utilized. Net operating loss carryforwards of approximately $42 million are scheduled to expire in fiscal year 2019. At June 29, 2018, the Company had U.S. federal and state tax credit carryforwards of $485 million and $114 million, respectively, which will expire at various dates beginning in fiscal year 2019, if not utilized.

As of June 29, 2018, approximately $501 million and $99 million of the Company’s total U.S. net operating loss and tax credit carryforwards, respectively, are subject to annual limitations ranging from $1 million to $45 million pursuant to U.S. tax law.

For purposes of the reconciliation between the provision for income taxes at the statutory rate and the effective tax rate, the Irish statutory rate of 25% was applied as follows:

	Fiscal Years Ended
(Dollars in millions)	June 29, 2018			June 30, 2017			July 1, 2016
Provision at statutory rate	$	355		$	204		$	69

A substantial portion of the Company’s operations in Malaysia, Singapore and Thailand operate under various tax incentive programs, which expire in whole or in part at various dates through 2027. Certain tax incentives may be extended if specific conditions are met. The net impact of these tax incentive programs was to increase the Company’s net income by approximately $269 million in fiscal year 2018 ($0.92 per share, diluted), to increase the Company’s net income by approximately $163 million in fiscal year 2017 ($0.54 per share, diluted), and to increase the Company’s net income by approximately $67 million in fiscal year 2016 ($0.22 per share, diluted).

The Company consists of an Irish tax resident parent holding company with various U.S. and non-U.S. subsidiaries that operate in multiple non-Irish taxing jurisdictions. The amount of temporary differences (including undistributed earnings) related to outside basis differences in the stock of non-Irish resident subsidiaries considered indefinitely reinvested outside of Ireland for which Irish income taxes have not been provided as of June 29, 2018, was approximately $1.8 billion. If such amounts were remitted to Ireland as a dividend, it is likely that tax at 25%, or approximately $450 million would result.

As of June 29, 2018 and June 30, 2017, the Company had approximately $60 million and $74 million, respectively, of unrecognized tax benefits excluding interest and penalties. The amount of unrecognized tax benefits that, if recognized, would impact the effective tax rate are $60 million and $74 million as of June 29, 2018 and June 30, 2017, respectively, subject to certain future valuation allowance offsets.

The following table summarizes the activity related to the Company’s gross unrecognized tax benefits:

	Fiscal Years Ended
(Dollars in millions)	June 29, 2018			June 30, 2017			July 1, 2016
Balance of unrecognized tax benefits at the beginning of the year	$	74		$	76		$	89

Non-U.S. exchange gain		—			—			(1	)
Balance of unrecognized tax benefits at the end of the year	$	60		$	74		$	76

It is the Company’s policy to include interest and penalties related to unrecognized tax benefits in the provision for income taxes on the Consolidated Statements of Operations. During fiscal year 2018, the Company recognized net income tax benefit for interest and penalties of $2 million, as compared to net income tax benefit of $1 million during fiscal year 2017, and income tax benefit of $8 million during fiscal year 2016. As of June 29, 2018, the Company had $2 million of accrued interest and penalties related to unrecognized tax benefits compared to $4 million in fiscal year 2017.

During the 12 months beginning June 30, 2018, the Company expects that its unrecognized tax benefits could be reduced by approximately $18 million as a result of the expiration of certain statutes of limitation.

The Company is required to file U.S. federal, U.S. state and non-U.S. income tax returns. The Company is no longer subject to examination of its U.S. federal income tax returns for years prior to fiscal year 2015. With respect to U.S. state and non-U.S. income tax returns, the Company is generally no longer subject to tax examination for years ending prior to fiscal year 2007.

8. Derivative Financial Instruments

The Company is exposed to foreign currency exchange rate, interest rate, and to a lesser extent, equity market risks relating to its ongoing business operations. From time to time, the Company enters into cash flow hedges in the form of foreign currency forward exchange contracts in order to manage the foreign currency exchange rate risk denominated in foreign currencies. The Company’s accounting policies for these instruments are based on whether the instruments are classified as designated or non-designated hedging instruments. The Company records all derivatives in the Consolidated Balance Sheets at fair value. The changes in the fair value of highly effective designated cash flow hedges are recorded in Accumulated other comprehensive loss until the hedged item is recognized in earnings. Derivatives that are not designated as hedging instruments or are not assessed to be highly effective are adjusted to fair value through earnings. The amount of net unrealized gain on cash flow hedges was less than $1 million as of June 29, 2018. The Company had no outstanding cash flow hedges as of June 30, 2017.

The Company de-designates its cash flow hedges when the forecasted hedged transactions affects earnings or it is probable the forecasted hedged transactions will not occur in the initially identified time period. At such time, the associated gains and losses deferred in Accumulated other comprehensive loss are reclassified immediately into earnings and any subsequent changes in the fair value of such derivative instruments are immediately reflected in earnings. The Company did not recognize any material amounts related to the loss of hedge designation on discontinued cash flow hedges during fiscal years 2018, 2017 and 2016.

Seagate Technology public limited company | 2018 Form 10-K | 82

Other derivatives not designated as hedging instruments consist of foreign currency forward exchange contracts that the Company uses to hedge the foreign currency exposure on the investment in debt security denominated in currency other than the U.S. dollar. The Company recognizes gains and losses on these contracts, as well as the related costs in Other, net on the Consolidated Statement of Operations along with foreign currency gains and losses on investment in debt security.

The following tables show the total notional value of the Company’s outstanding foreign currency forward exchange contracts as of June 29, 2018. All these foreign currency forward contracts mature within 12 months.

The Company did not have outstanding foreign currency forward exchange contracts as of June 30, 2017

The Company is subject to equity market risks due to changes in the fair value of the notional investments selected by its employees as part of its Non-qualified Deferred Compensation Plan – the Seagate Deferred Compensation Plan (the “SDCP”). In fiscal year 2014, the Company entered into a Total Return Swap (“TRS”) in order to manage the equity market risks associated with the SDCP liabilities. The Company pays a floating rate, based on LIBOR plus an interest rate spread, on the notional amount of the TRS. The TRS is designed to substantially offset changes in the SDCP liability due to changes in the value of the investment options made by employees. As of June 29, 2018, the notional investments underlying the TRS amounted to $114 million. The contract term of the TRS is through January 2019 and is settled on a monthly basis, therefore limiting counterparty performance risk. The Company did not designate the TRS as a hedge. Rather, the Company records all changes in the fair value of the TRS to earnings to offset the market value changes of the SDCP liabilities.

The following tables show the Company’s derivative instruments measured at gross fair value as reflected in the Consolidated Balance Sheet as of June 29, 2018:

	As of June 29, 2018
	Derivative Assets				Derivative Liabilities
(Dollars in millions)	Balance Sheet Location		Fair Value		Balance Sheet Location		Fair Value

As of June 30, 2017, the Company did not have outstanding foreign currency forward exchange contracts and the gross fair value of the TRS reflected in the Consolidated Balance Sheets is immaterial.

The amount of gain or loss recognized in the Consolidated Statement of Comprehensive Income on derivatives designated as cash flow hedges was less than $1 million as of June 29, 2018. The following table shows the effect of the Company’s derivative instruments on the Consolidated Statement of Operations for the fiscal year ended June 29, 2018:

9. Fair Value

Measurement of Fair Value

Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

Fair Value Hierarchy

A fair value hierarchy is based on whether the market participant assumptions used in determining fair value are obtained from independent sources (observable inputs) or reflects the Company’s own assumptions of market participant valuation (unobservable inputs). A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of inputs that may be used to measure fair value are:

Level 1 – Quoted prices in active markets that are unadjusted and accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 – Quoted prices for identical assets and liabilities in markets that are inactive; quoted prices for similar assets and liabilities in active markets or financial instruments for which significant inputs are observable, either directly or indirectly; or

Level 3 – Prices or valuations that require inputs that are both unobservable and significant to the fair value measurement.

The Company considers an active market to be one in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis, and views an inactive market as one in which there are few transactions for the asset or liability, the prices are not current, or price quotations vary substantially either over time or among market makers. Where appropriate, the Company’s or the counterparty’s non-performance risk is considered in determining the fair values of liabilities and assets, respectively.

The Company classifies items in Level 1 if the financial assets consist of securities for which quoted prices are available in an active market.

The Company classifies items in Level 2 if the financial asset or liability is valued using observable inputs. The Company uses observable inputs including quoted prices in active markets for similar assets or liabilities. Level 2 assets include: agency bonds, corporate bonds, commercial paper, municipal bonds, U.S. Treasuries, time deposits and certificates of deposit. These debt investments are priced using observable inputs and valuation models which vary by asset class. The Company uses a pricing service to assist in determining the fair values of all of its cash equivalents and short-term investments. For the cash equivalents and short-term investments in the Company’s portfolio, multiple pricing sources are generally available. The pricing service uses inputs from multiple industry standard data providers or other third party sources and various methodologies, such as weighting and models, to determine the appropriate price at the measurement date. The Company corroborates the prices obtained from the pricing service against other independent sources and, as of June 29, 2018, has not found it necessary to make any adjustments to the prices obtained. The Company’s derivative financial instruments are also classified within Level 2. The Company’s derivative financial instruments consist of foreign currency forward exchange contracts and the TRS. The Company recognizes derivative financial instruments in its consolidated financial statements at fair value. The Company determines the fair value of these instruments by considering the estimated amount it would pay or receive to terminate these agreements at the reporting date.

Seagate Technology public limited company | 2018 Form 10-K | 86

As of June 29, 2018 and June 30, 2017, the Company had no Level 3 assets or liabilities measured at fair value on a recurring basis.

Items Measured at Fair Value on a Non-Recurring Basis

From time to time, the Company enters into certain strategic investments for the promotion of business and strategic objectives. These strategic investments primarily include cost basis investments representing those where the Company does not have the ability to exercise significant influence as well as equity method investments representing those where the Company does have the ability to exercise significant influence but does not have control. These investments are included in Other assets, net in the Consolidated Balance Sheets, and are periodically analyzed to determine whether or not there are indicators of impairment. The carrying value of the Company’s strategic investments at June 29, 2018 and June 30, 2017 totaled $118 million and $125 million, respectively, and consisted primarily of privately held equity securities without a readily determinable fair value.

During the fiscal years 2018, 2017 and 2016, the Company determined that certain of its equity investments accounted for under the cost method were other-than-temporarily impaired, and recognized charges of $11 million, $25 million and $13 million, respectively, in order to write down the carrying amount of the investments to its estimated fair value. Since there was no active market for the equity securities of the investee, the Company estimated fair value of the investee by analyzing the underlying cash flows and future prospects of the investee. These amounts were recorded in Other, net in the Consolidated Statements of Operations.

As of June 30, 2017, the Company had $77 million of held for sale land and buildings (collectively, the “Properties”) primarily in Asia included in Other current assets on the Consolidated Balance Sheet. The respective Properties to be sold met the criteria to be classified as held for sale in fiscal year 2017. Depreciation related to the Properties ceased as of the date these were determined to be held for sale. During fiscal year 2017, the Company recorded impairment charges of $35 million in order to write down the carrying amount of such properties to their estimated fair values less costs to sell. The impairment charges were recorded in Operating expenses in the Consolidated Statements of Operations. During fiscal year 2018, the Company completed the sale of certain of these properties and recorded a gain of approximately $25 million, which was included in Restructuring and other, net in the Consolidated Statements of Operations. As of June 29, 2018, the Company had one Property held at $26 million, that continues to be held-for-sale and included in Other current assets on the Consolidated Balance Sheet. No impairment charge was recorded in fiscal year 2018. The fair value of the Property was measured using inputs such as comparable market data for similar land sale transactions adjusted for differences in comparable properties to derive the estimated fair value of the subject property and the cost approach valuation techniques for building as part of the analysis. The fair value measurement was categorized as Level 3 as significant unobservable inputs were used in the valuation analysis.

Other Fair Value Disclosures

The Company’s investment in debt security, classified as held-to-maturity, represents shares of non-convertible preferred stock of K.K. Pangea for the acquisition of Toshiba Memory Corporation by a consortium of investors led by Bain Capital Private Equity. This debt security has a maturity date of six years and is classified as Investment in debt security on the Company’s Consolidated Balance Sheet. The debt security is recorded at amortized cost and its fair value approximates the carrying value at June 29, 2018. The fair value was determined utilizing Level 2 inputs such as discount rates and yield terms of similar types of securities issued by comparable companies.

Seagate Technology public limited company | 2018 Form 10-K | 87

The Company’s debt is carried at amortized cost. The fair value of the Company’s debt is derived using the closing price of the same debt instruments as of the date of valuation, which takes into account the yield curve, interest rates and other observable inputs. Accordingly, these fair value measurements are categorized as Level 2. The following table presents the fair value and amortized cost of the Company’s debt in order of maturity:

10. Shareholders’ Equity

Share Capital

The Company’s authorized share capital is $13,500 and consists of 1,250,000,000 ordinary shares, par value $0.00001, of which 287,170,363 shares were outstanding as of June 29, 2018, and 100,000,000 preferred shares, par value $0.00001, of which none were issued or outstanding as of June 29, 2018.

Ordinary shares – Holders of ordinary shares are entitled to receive dividends when and as declared by the Company’s board of directors (the “Board of Directors”). Upon any liquidation, dissolution, or winding up of the Company, after required payments are made to holders of preferred shares, any remaining assets of the Company will be distributed ratably to holders of the preferred and ordinary shares. Holders of shares are entitled to one vote per share on all matters upon which the ordinary shares are entitled to vote, including the election of directors.

Preferred shares – The Company may issue preferred shares in one or more series, up to the authorized amount, without shareholder approval. The Board of Directors is authorized to establish from time to time the number of shares to be included in each series, and to fix the rights, preferences and privileges of the shares of each wholly unissued series and any of its qualifications, limitations or restrictions. The Board of Directors can also increase or decrease the number of shares of a series, but not below the number of shares of that series then outstanding, without any further vote or action by the shareholders.

The Board of Directors may authorize the issuance of preferred shares with voting or conversion rights that could harm the voting power or other rights of the holders of the ordinary shares. The issuance of preferred shares, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in control of the Company and might harm the market price of its ordinary shares and the voting and other rights of the holders of ordinary shares.

Repurchases of Equity Securities

All repurchases are effected as redemptions in accordance with the Company’s Articles of Association.

Seagate Technology public limited company | 2018 Form 10-K | 88

11. Share-based Compensation

Share-Based Compensation Plans

The Company’s share-based compensation plans have been established to promote the Company’s long-term growth and financial success by providing incentives to its employees, directors and consultants through grants of share-based awards. The provisions of the Company’s share-based benefit plans, which allow for the grant of various types of equity-based awards, are also intended to provide greater flexibility to maintain the Company’s competitive ability to attract, retain and motivate participants for the benefit of the Company and its shareholders.

Seagate Technology plc 2012 Equity Incentive Plan (the “EIP”). On October 26, 2011, the shareholders approved the EIP and authorized the issuance of up to a total of 27.0 million ordinary shares, par value $0.0001 per share, plus any shares remaining available for grant under the Seagate Technology plc 2004 Share Compensation Plan (the “SCP”) as of the effective date of the EIP (which was equal to 11.0 million ordinary shares as of the effective date of the EIP and which will increase by such additional number of shares as will be returned to the share reserve in respect of awards previously granted under the SCP) (together, the “Share Reserve”). On October 22, 2014, the shareholders authorized the issuance from the EIP of an additional 25 million ordinary shares, par value $0.0001 per share. Any shares that are subject to options or share appreciation rights granted under the EIP will be counted against the Share Reserve as one share for every one share granted, and any shares that are subject to restricted share bonus awards, restricted share units, performance share bonus awards or performance share awards (collectively, “Full-Value Share Awards”) will generally be counted against the Share Reserve as two and five-tenths shares for every one share granted. On October 19, 2016, the shareholders authorized the issuance from the EIP of an additional 7.5 million ordinary shares, par value $0.0001 per share. As of June 29, 2018, there were approximately 25.7 million ordinary shares available for issuance under the EIP.

Dot Hill Systems 2009 Equity Incentive Plan (the “DHEIP”). Seagate Technology plc acquired the Dot Hill Systems 2009 Equity Incentive Plan effective October 6, 2015. The Company assumed the remaining authorized but unused share reserve of approximately 2 million shares, based on the conversion ratio, from the DHEIP on the acquisition date. Any shares that are subject to options or share appreciation rights granted under the DHEIP will be counted against the Share Reserve as one share for every one share granted, and any shares that are subject to restricted share bonus awards, restricted share units, performance share bonus awards or performance share awards (collectively, “Full-Value Share Awards”) will generally be counted against the Share Reserve as one and five-tenths shares for every one share granted. As of June 29, 2018, there were approximately 1 million ordinary shares available for issuance under the DHEIP.

Seagate Technology public limited company | 2018 Form 10-K | 89

Seagate Technology plc Employee Stock Purchase Plan (the “ESPP”). There are 60.0 million ordinary shares authorized to be issued under the ESPP. The ESPP consists of a six-month offering period with a maximum issuance of 1.5 million ordinary shares per offering period. The ESPP permits eligible employees to purchase ordinary shares through payroll deductions generally at 85% of the fair market value of the ordinary shares. As of June 29, 2018, there were approximately 12.8 million ordinary shares available for issuance under the ESPP.

Equity Awards

Full-Value Share Awards (e.g. restricted share units, “RSU”) generally vest over a period of three to four years, with cliff vesting of a portion of each award occurring annually, subject to continuous employment with the Company through the vesting date. Options generally vest as follows: 25% of the options will vest on the first anniversary of the vesting commencement date and the remaining 75% will vest ratably each month thereafter over the next 36 months. Options granted under the EIP and SCP have an exercise price equal to the fair market value of the Company’s ordinary shares on the grant date. Fair market value is defined as the closing price of the Company’s ordinary shares on NASDAQ on the grant date.

The Company granted awards of performance-based share units (“PSU”) to its senior executive officers under the SCP and the EIP where vesting is subject to both the continued employment of the participant by the Company and the achievement of certain performance goals established by the Compensation Committee of the Company’s Board of Directors, including market-based performance goals. A single PSU represents the right to receive a single ordinary share of the Company. During fiscal years 2018, 2017 and 2016, the Company granted 0.4 million, 0.6 million and 0.4 million PSUs, respectively, where performance is measured based on a three-year average return on invested capital (“ROIC”) goal and a relative total shareholder return (“TSR”) goal, which is based on the Company’s ordinary shares measured against a benchmark TSR of a peer group over the same three-year period (the “TSR/ROIC” awards). These awards vest after the end of the performance period of three years from the grant date. A percentage of these units may vest only if at least the minimum ROIC goal is met regardless of whether the TSR goal is met. The number of share units to vest will range from 0% to 200% of the targeted units. In evaluating the fair value of these units, the Company used a Monte Carlo simulation on the grant date, taking the market-based TSR goal into consideration. Compensation expense related to these units is only recorded in a period if it is probable that the ROIC goal will be met, and it is to be recorded at the expected level of achievement.

The Company also granted 0.2 million, 0.2 million and 0.2 million PSUs during fiscal years 2018, 2017 and 2016, respectively, to its senior executive officers which are subject to a performance goal related to the Company’s adjusted earnings per share (the “AEPS” awards). These awards have a maximum seven-year vesting period, with 25% annual vesting starting on the first anniversary of the grant date. If the performance goal is not achieved, vesting is delayed to a following year in which the AEPS goal is achieved. Any unvested awards from prior years may vest cumulatively in a future year within the seven-year vesting period if the annual AEPS goal is achieved during a subsequent year. If the AEPS goal has not been met by the end of the seven year period, any unvested shares will be forfeited.

Valuation and amortization method – The Company estimates the fair value of stock options, RSU and performance awards subject to an AEPS condition granted using the Black-Scholes-Merton valuation model and a single share award approach. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period or the remaining service (vesting) period.

Expected Term – Expected term represents the period that the Company’s share-based awards are expected to be outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual terms of the share-based awards, vesting schedules and expectations of future employee behavior as influenced by changes to the terms of its share-based awards.

Expected Volatility – The Company uses a combination of the implied volatility of its traded options and historical volatility of its share price.

Expected Dividend – The Black-Scholes-Merton valuation model calls for a single expected dividend yield as an input. The dividend yield is determined by dividing the expected per share dividend during the coming year by the grant date share price.

Seagate Technology public limited company | 2018 Form 10-K | 90

The expected dividend assumption is based on the Company’s current expectations about its anticipated dividend policy. Also, because the expected dividend yield should reflect marketplace participants’ expectations, the Company does not incorporate changes in dividends anticipated by management unless those changes have been communicated to or otherwise are anticipated by marketplace participants.

Risk-Free Interest Rate – The Company bases the risk-free interest rate used in the Black-Scholes-Merton valuation model on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term. Where the expected term of the Company’s share-based awards do not correspond with the terms for which interest rates are quoted, the Company performed a straight-line interpolation to determine the rate from the available term maturities.

Share-based Compensation Expense

The Company recorded $112 million, $137 million and $120 million of share-based compensation during fiscal years 2018, 2017 and 2016, respectively. Management has made an estimate of expected forfeitures and is recognizing compensation costs only for those equity awards expected to vest. When estimating forfeitures, the Company considers voluntary termination behavior as well as analysis of actual forfeited awards.

Seagate Technology public limited company | 2018 Form 10-K | 92

Stock Option Activity

The Company issues new ordinary shares upon exercise of stock options. The following is a summary of option activities:    

Options	Number of Shares (In millions)			Weighted- Average Exercise Price		Weighted-Average Remaining Contractual Term (In years)		Aggregate Intrinsic Value (Dollars in millions)
Outstanding at June 30, 2017		5.7		$	39.24		5.0	$	22
Granted		1.4		$	33.67
Exercised		(1.8	)	$	32.66
Forfeitures		(1.0	)	$	38.61
Expirations		(0.3	)	$	54.18
Outstanding at June 29, 2018		4.0		$	39.00		5.0	$	72
Vested and expected to vest at June 29, 2018		3.9		$	39.10		5.0	$	70
Exercisable at June 29, 2018		1.4		$	44.26		4.0	$	19

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted price of the Company’s ordinary shares for the options that were in-the-money at June 29, 2018. During fiscal years 2018, 2017 and 2016, the aggregate intrinsic value of options exercised under the Company’s stock option plans was $34 million, $29 million and $44 million, respectively, determined as of the date of option exercise. The aggregate fair value of options vested during fiscal years 2018, 2017 and 2016 were approximately $12 million, $15 million and $18 million, respectively.

At June 29, 2018, the total compensation cost related to options granted to employees but not yet recognized was approximately $16 million, net of estimated forfeitures of approximately $1 million. This cost is being amortized on a straight-line basis over a weighted-average remaining term of approximately 2.6 years and will be adjusted for subsequent changes in estimated forfeitures.

Nonvested Awards Activity

The following is a summary of nonvested award activities which do not contain a performance condition:

Nonvested Awards	Number of Shares (In millions)			Weighted-Average Grant- Date Fair Value
Nonvested at June 30, 2017		5.2		$	35.75
Granted		2.7		$	26.69
Forfeitures		(0.7	)	$	34.69
Vested		(2.0	)	$	36.71
Nonvested at June 29, 2018		5.2		$	30.74

At June 29, 2018, the total compensation cost related to nonvested awards granted to employees but not yet recognized was approximately $105 million, net of estimated forfeitures of approximately $9 million. This cost is being amortized on a straight-line basis over a weighted-average remaining term of 2.5 years and will be adjusted for subsequent changes in estimated forfeitures. The aggregate fair value of nonvested awards vested during fiscal years 2018, 2017 and 2016 were approximately $76 million, $73 million and $102 million, respectively.

Performance Awards

The following is a summary of nonvested award activities which contain a performance condition:

Performance Awards	Number  of Shares (In millions)			Weighted-Average Grant-Date Fair Value
Performance units at June 30, 2017		1.5		$	41.88
Granted		0.5		$	26.28
Forfeitures		(0.5	)	$	40.84
Vested		(0.3	)	$	48.02
Performance units at June 29, 2018		1.2		$	33.34

At June 29, 2018, the total compensation cost related to performance awards granted to employees but not yet recognized was approximately $23 million, net of estimated forfeitures of approximately $3 million. This cost is being amortized on a straight-line basis over a weighted-average remaining term of 1.50 years.

ESPP

During fiscal years 2018, 2017 and 2016, the aggregate intrinsic value of shares purchased under the Company’s ESPP was approximately $31 million, $24 million and $12 million, respectively. At June 29, 2018, the total compensation cost related to options to purchase the Company’s ordinary shares under the ESPP but not yet recognized was approximately $1.4 million. This cost will be amortized on a straight-line basis over a weighted-average period of approximately one month. During fiscal year 2018, the Company issued 2.0 million ordinary shares with a weighted-average exercise price of $28.19 per share.

Tax-Deferred Savings Plan

The Company has a tax-deferred savings plan, the Seagate 401(k) Plan (the “40l(k) plan”), for the benefit of qualified employees. The 40l(k) plan is designed to provide employees with an accumulation of funds at retirement. Qualified employees may elect to make contributions to the 401(k) plan on a bi-weekly basis. Pursuant to the 401(k) plan, the Company matches 50% of employee contributions, up to 6% of compensation, subject to maximum annual contributions of $6,000 per participating employee. During fiscal years 2018, 2017 and 2016, the Company made matching contributions of $16 million, $18 million and $19 million, respectively.

Deferred Compensation Plan

On January 1, 2001, the Company adopted the SDCP for the benefit of eligible employees. This plan is designed to permit certain discretionary employer contributions, in excess of the tax limits applicable to the 401(k) plan and to permit employee deferrals in excess of certain tax limits. During fiscal year 2014, the Company entered into a TRS in order to manage the equity market risks associated with the SDCP liabilities. See Note 8. Derivative Financial Instruments contained in this report for additional information about the TRS.

12. Earnings Per Share

Basic earnings per share is computed by dividing income available to shareholders by the weighted-average number of shares outstanding during the period. Diluted earnings per share is computed by dividing income available to shareholders by the weighted-average number of shares outstanding during the period and the number of additional shares that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding options, unvested restricted stock units and performance-based share units and shares to be purchased under the Employee Stock Purchase Plan (“ESPP”). The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method. Under the treasury stock method, an increase in fair market value of the Company’s share price can result in a greater dilutive effect from potentially dilutive securities. The following table sets forth the computation of basic and diluted net income per share attributable to the shareholders of the Company:

	Fiscal Years Ended
(In millions, except per share data)	June 29, 2018		June 30, 2017		July 1, 2016
Numerator:
Net income	$	1,182	$	772	$	248
Number of shares used in per share calculations:
Total shares for purposes of calculating basic net income per share		288		296		299
Weighted-average effect of dilutive securities:
Employee equity award plans		4		3		3
Total shares for purposes of calculating diluted net income per share		292		299		302
Net income per share
Basic	$	4.10	$	2.61	$	0.83
Diluted	$	4.05	$	2.58	$	0.82

The following potential shares were excluded from the computation of diluted net income per share as their effect would have been anti-dilutive:

14. Legal, Environmental and Other Contingencies

The Company assesses the probability of an unfavorable outcome of all its material litigation, claims, or assessments to determine whether a liability had been incurred and whether it is probable that one or more future events will occur confirming the fact of the loss. In the event that an unfavorable outcome is determined to be probable and the amount of the loss can be reasonably estimated, the Company establishes an accrual for the litigation, claim or assessment. In addition, in the event an unfavorable outcome is determined to be less than probable, but reasonably possible, the Company will disclose an estimate of the possible loss or range of such loss; however, when a reasonable estimate cannot be made, the Company will provide disclosure to that effect. Litigation is inherently uncertain and may result in adverse rulings or decisions. Additionally, the Company may enter into settlements or be subject to judgments that may, individually or in the aggregate, have a material adverse effect on its results of operations. Accordingly, actual results could differ materially.

Intellectual Property Litigation

Convolve, Inc. (“Convolve”) and Massachusetts Institute of Technology (“MIT”) v. Seagate Technology LLC, et al.-On July 13, 2000, Convolve and MIT filed suit against Compaq Computer Corporation and Seagate Technology LLC in the U.S. District Court for the Southern District of New York, alleging infringement of U.S. Patent No. 4,916,635 (the “‘635 patent”) and U.S. Patent No. 5,638,267 (the “‘267 patent”), misappropriation of trade secrets, breach of contract, and other claims. On January 16, 2002, Convolve filed an amended complaint, alleging defendants were infringing U.S. Patent No. 6,314,473 (the “‘473 patent”). The district court ruled in 2010 that the ‘267 patent was out of the case.

On August 16, 2011, the district court granted in part and denied in part the Company’s motion for summary judgment. On July 1, 2013, the U.S. Court of Appeals for the Federal Circuit: 1) affirmed the district court’s summary judgment rulings that Seagate did not misappropriate any of the alleged trade secrets and that the asserted claims of the ‘635 patent are invalid; 2) reversed and vacated the district court’s summary judgment of non-infringement with respect to the ‘473 patent; and

Seagate Technology public limited company | 2018 Form 10-K | 96

3) remanded the case for further proceedings on the ‘473 patent. On July 11, 2014, the district court granted the Company’s further summary judgment motion regarding the ‘473 patent. On February 10, 2016, the U.S. Court of Appeals for the Federal Circuit: 1) affirmed the district court’s summary judgment of no direct infringement by Seagate because Seagate’s ATA/SCSI disk drives do not meet the “user interface” limitation of the asserted claims of the ‘473 patent; 2) affirmed the district court’s summary judgment of non-infringement by Compaq’s products as to claims 1, 3, and 5 of the ‘473 patent because Compaq’s F10 BIOS interface does not meet the “commands” limitation of those claims; 3) vacated the district court’s summary judgment of non-infringement by Compaq’s accused products as to claims 7-15 of the ‘473 patent; 4) reversed the district court’s summary judgment of non-infringement based on intervening rights; and 5) remanded the case to the district court for further proceedings on the ‘473 patent. In view of the rulings made by the district court and the Court of Appeals and the uncertainty regarding the amount of damages, if any, that could be awarded Convolve in this matter, the Company does not believe that it is currently possible to determine a reasonable estimate of the possible range of loss related to this matter.

Enova Technology Corporation v. Seagate Technology (US) Holdings, Inc., et al.-On June 5, 2013, Enova Technology Corporation (“Enova”) filed a complaint against Seagate Technology (US) Holdings, Inc. and Seagate Technology LLC in the U.S. District Court for the District of Delaware alleging infringement of U.S. Patent No. 7,136,995 (the “‘995 patent”), “Cryptographic Device,” and U.S. Patent No. 7,900,057 (the “‘057 patent”), “Cryptographic Serial ATA Apparatus and Method.” The Company believes the claims are without merit and intends to vigorously defend this case. On April 27, 2015, the district court ordered a stay of the case, in view of proceedings regarding the ‘995 and ‘057 patents before the Patent Trial and Appeal Board (“PTAB”) of the U.S. Patent and Trademark Office. On September 2, 2015, PTAB issued its final written decision that claims 1-15 of the ‘995 patent are held unpatentable. On December 18, 2015, PTAB issued its final written decisions that claims 1-32 and 40-53 of the ‘057 patent are held unpatentable. On February 4, 2016, PTAB issued its final written decision that claims 33-39 of the ‘057 patent are held unpatentable. Enova appealed PTAB’s decisions on the ‘995 patent and the ‘057 patent to the U.S. Court of Appeals for the Federal Circuit. On March 20, 2017, the court of appeals issued its judgment affirming PTAB’s decision on the ‘995 patent. On September 6, 2017, the court of appeals issued its judgment affirming PTAB’s decision on the ‘057 patent. On November 27, 2017, Enova filed a petition for writ of certiorari with the U.S. Supreme Court challenging the court of appeals’ decision on the ‘057 Patent. The Supreme Court denied the petition on April 30, 2018. On May 9, 2018, the district court entered a final judgment of dismissal with prejudice and on the merits on all claims asserted by Enova in its complaint, with each party to bear its own costs and attorneys’ fees. In light of the district court’s final judgment of dismissal, the Company does not expect to incur a loss in this matter.

Lambeth Magnetic Structures LLC v. Seagate Technology (US) Holdings, Inc., et al.-On April 29, 2016, Lambeth Magnetic Structures LLC filed a complaint against Seagate Technology (US) Holdings, Inc. and Seagate Technology LLC in the U.S. District Court for the Western District of Pennsylvania, alleging infringement of U.S. Patent No. 7,128,988, “Magnetic Material Structures, Devices and Methods.” The Company believes the claims asserted in the complaint are without merit and intends to vigorously defend this case. The court issued its claim construction ruling on October 18, 2017. No trial date has been set. While the possible range of loss for this matter remains uncertain, the Company estimates the amount of loss to be immaterial to the financial statements.

Environmental Matters

The Company’s operations are subject to U.S. and foreign laws and regulations 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 wastes and the cleanup of contaminated sites. Some of the Company’s operations require environmental permits and controls to prevent and reduce air and water pollution, and these permits are subject to modification, renewal and revocation by issuing authorities.

The Company has established environmental management systems and continually updates its environmental policies and standard operating procedures for its operations worldwide. The Company believes that its operations are in material compliance with applicable environmental laws, regulations and permits. The Company budgets for operating and capital costs on an ongoing basis to comply with environmental laws. If additional or more stringent requirements are imposed on the Company in the future, it could incur additional operating costs and capital expenditures.

Some environmental laws, such as the Comprehensive Environmental Response Compensation and Liability Act of 1980 (as amended, the “Superfund” law) and its state equivalents, can impose liability for the cost of cleanup of contaminated sites

Seagate Technology public limited company | 2018 Form 10-K | 97

upon any of the current or former site owners or operators or upon parties who sent waste to these sites, regardless of whether the owner or operator owned the site at the time of the release of hazardous substances or the lawfulness of the original disposal activity. The Company has been identified as a responsible or potentially responsible party at several sites. At each of these sites, the Company has an assigned portion of the financial liability based on the type and amount of hazardous substances disposed of by each party at the site and the number of financially viable parties. The Company has fulfilled its responsibilities at some of these sites and remains involved in only a few at this time.

While the Company’s ultimate costs in connection with these sites is difficult to predict with complete accuracy, based on its current estimates of cleanup costs and its expected allocation of these costs, the Company does not expect costs in connection with these sites to be material.

The Company may be subject to various state, federal and international laws and regulations governing the environment, including those restricting the presence of certain substances in electronic products. For example, the European Union (“EU”) enacted the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment, which prohibits the use of certain substances, including lead, in certain products, including disk drives and server storage products, put on the market after July 1, 2006. Similar legislation has been or may be enacted in other jurisdictions, including in the United States, Canada, Mexico, Taiwan, China, Japan and others. The European Union REACH Directive (Registration, Evaluation, Authorization, and Restriction of Chemicals, EC 1907/2006) also restricts substances of very high concern (“SVHCs”) in products. If the Company or its suppliers fails to comply with the substance restrictions, recycle requirements or other environmental requirements as they are enacted worldwide, it could have a materially adverse effect on the Company’s business.

Other Matters

The Company is involved in a number of other judicial, regulatory or administrative proceedings and investigations incidental to its business, and the Company may be involved in such proceedings and investigations arising in the normal course of its business in the future. Although occasional adverse decisions or settlements may occur, the Company believes that the final disposition of such matters will not have a material adverse effect on its financial position or results of operations.

15. Commitments

Leases. The Company leases certain property, facilities and equipment under non-cancelable lease agreements. Land and facility leases expire at various dates through 2082 and contain various provisions for rental adjustments including, in certain cases, a provision based on increases in the Consumer Price Index. In addition, certain leases provide for renewal of the lease at the Company’s option at expiration of the lease. The lease term begins on the date of initial possession of the leased property for purposes of recognizing lease expense on a straight-line basis over the term of the lease. The Company does not assume renewals in its determination of the lease term unless the renewals are deemed to be reasonably assured at lease inception. All of the leases require the Company to pay property taxes, insurance and normal maintenance costs, which are expensed as incurred.

Seagate Technology public limited company | 2018 Form 10-K | 98

Future minimum lease payments for operating leases (including accrued lease payments relating to restructuring plans) with initial or remaining terms of one year or more were as follows at June 29, 2018 (lease payments are shown net of sublease income):

Fiscal Years Ending	Operating Leases (Dollars in  millions)
2019	$	13
2020		9
2021		6
2022		6
2023		5
Thereafter		70
	$	109

Total rent expense for all land, facility and equipment operating leases, net of sublease income, was $22 million, $29 million and $43 million for fiscal years 2018, 2017 and 2016, respectively. Total sublease rental income for fiscal years 2018, 2017 and 2016 was $3 million, $2 million and $3 million, respectively. The Company subleases a portion of its facilities that it considers to be in excess of current requirements. As of June 29, 2018, total future lease income to be recognized for the Company’s existing subleases is approximately $17 million.

Capital Expenditures. The Company’s non-cancelable commitments for construction of manufacturing and product development facilities and purchases of equipment approximated $256 million at June 29, 2018.

16. Guarantees

Indemnifications of Officers and Directors

On May 4, 2009, Seagate Technology, an exempted company incorporated with limited liability under the laws of the Cayman Islands (“Seagate-Cayman”), then the parent company, entered into a new form of indemnification agreement (the “Revised Indemnification Agreement”) with its officers and directors of Seagate-Cayman and its subsidiaries (each, an “Indemnitee”). The Revised Indemnification Agreement provides indemnification in addition to any of Indemnitee’s indemnification rights under Seagate-Cayman’s Articles of Association, applicable law or otherwise, and indemnifies an Indemnitee for certain expenses (including attorneys’ fees), judgments, fines and settlement amounts actually and reasonably incurred by him or her in any action or proceeding, including any action by or in the right of Seagate-Cayman or any of its subsidiaries, arising out of his or her service as a director, officer, employee or agent of Seagate-Cayman or any of its subsidiaries or of any other entity to which he or she provides services at Seagate-Cayman’s request. However, an Indemnitee shall not be indemnified under the Revised Indemnification Agreement for (i) any fraud or dishonesty in the performance of Indemnitee’s duty to Seagate-Cayman or the applicable subsidiary of Seagate-Cayman or (ii) Indemnitee’s conscious, intentional or willful failure to act honestly, lawfully and in good faith with a view to the best interests of Seagate-Cayman or the applicable subsidiary of Seagate-Cayman. In addition, the Revised Indemnification Agreement provides that Seagate-Cayman will advance expenses incurred by an Indemnitee in connection with enforcement of the Revised Indemnification Agreement or with the investigation, settlement or appeal of any action or proceeding against him or her as to which he or she could be indemnified.

On July 3, 2010, pursuant to a corporate reorganization, the common shareholders of Seagate-Cayman became ordinary shareholders of Seagate Technology plc (the “Company”) and Seagate-Cayman became a wholly owned subsidiary of the Company, as described more fully in the Current Report on Form 8-K filed by the Company on July 6, 2010 (the “Redomestication”). On July 27, 2010, in connection with the Redomestication, the Company, as sole shareholder of Seagate-Cayman, approved a form of deed of indemnity (the “Deed of Indemnity”), which provides for the indemnification by Seagate-Cayman of any director, officer, employee or agent of the Company, Seagate-Cayman or any subsidiary of the Company (each, a “Deed Indemnitee”), in addition to any indemnification rights of a Deed Indemnitee under the Company’s Articles of Association, applicable law or otherwise, with a similar scope to the Revised Indemnification Agreement. Seagate-Cayman entered into Deeds of Indemnity with certain Deed Indemnitees effective as of July 3, 2010 and continues to enter into Deeds of Indemnity with additional Deed Indemnitees from time to time.

The nature of these indemnification obligations prevents the Company from making a reasonable estimate of the maximum potential amount it could be required to pay on behalf of its officers and directors. Historically, the Company has not made any significant indemnification payments under such agreements and no amount has been accrued in the Company’s consolidated financial statements with respect to these indemnification obligations.

Intellectual Property Indemnification Obligations

The Company has entered into agreements with customers and suppliers that include limited intellectual property indemnification obligations that are customary in the industry. These guarantees generally require the Company to compensate the other party for certain damages and costs incurred as a result of third party intellectual property claims arising from these transactions. The nature of the intellectual property indemnification obligations prevents the Company from making a reasonable estimate of the maximum potential amount it could be required to pay to its customers and suppliers. Historically, the Company has not made any significant indemnification payments under such agreements and no amount has been accrued in the Company’s consolidated financial statements with respect to these indemnification obligations.

Product Warranty

The Company estimates probable product warranty costs at the time revenue is recognized. The Company generally warrants its products for a period of 1 to 5 years. The Company uses estimated repair or replacement costs and uses statistical modeling to estimate product return rates in order to determine its warranty obligation. Changes in the Company’s product warranty liability during the fiscal years ended June 29, 2018, June 30, 2017 and July 1, 2016 were as follows:

	Fiscal Years Ended
(In millions)	June 29, 2018			June 30, 2017			July 1, 2016
Balance, beginning of period	$	233		$	206		$	248
Warranties issued		147			131			125

Warranty liability assumed from acquisitions		—			—			2
Balance, end of period	$	237		$	233		$	206

Morton, Jr., Executive Vice President and Chief Financial Officer, will leave the Company on August 3, 2018. The Company will be initiating a search for a successor CFO and, following Mr. Morton’s departure, Kathryn R.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of Seagate Technology public limited company

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Seagate Technology public limited company (plc) (the Company) as of June 29, 2018 and June 30, 2017, the related consolidated statements of operations, comprehensive income, shareholders’ equity and cash flows for each of the three years in the period ended June 29, 2018, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at June 29, 2018 and June 30, 2017, and the results of its operations and its cash flows for each of the three years in the period ended June 29, 2018, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of June 29, 2018, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated August 3, 2018 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of Seagate Technology public limited company

Opinion on Internal Control over Financial Reporting

We have audited Seagate Technology public limited company (plc)’s internal control over financial reporting as of June 29, 2018, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Seagate Technology public limited company (plc) (the Company) maintained, in all material respects, effective internal control over financial reporting as of June 29, 2018, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of June 29, 2018 and June 30, 2017, and the related consolidated statements of operations, comprehensive income, shareholders’ equity and cash flows for each of the three years in the period ended June 29, 2018 and the related notes and our report dated August 3, 2018 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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 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.

For quarterly financial data see “Part II, Item 6. Selected Financial Data.”

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

Not applicable.

ITEM 9A. CONTROLS AND PROCEDURES

Conclusions Regarding Disclosure Controls and Procedures

Our chief executive officer and our chief financial officer have concluded, based on the evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended) by our management, with the participation of our chief executive officer and our chief financial officer, that our disclosure controls and procedures were effective as of June 29, 2018.

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) under the Securities Exchange Act of 1934, as amended). Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO.

Based on our evaluation under the 2013 framework in Internal Control—Integrated Framework, our management has concluded that our internal control over financial reporting was effective as of June 29, 2018. The effectiveness of our internal control over financial reporting as of June 29, 2018 has been audited by Ernst & Young LLP, the independent registered public accounting firm that audited our financial statements included in this Annual Report on Form 10-K, as stated in their report that is included herein.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during our fourth fiscal quarter that have materially affected, or were reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Controls

Our management, including our chief executive officer and chief financial officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all errors 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 design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Our disclosure controls and procedures and our internal controls have been designed to provide reasonable assurance of achieving their objectives. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Seagate have been detected. An evaluation was performed 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 of June 29, 2018. Based on that evaluation, our management, including our chief executive officer and chief financial officer, concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

Accounting Policies [Abstract]

Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Summary of Significant Accounting Policies

Organization

Seagate Technology plc (the "Company") is a leading provider of data storage technology and solutions. Its principal products are hard disk drives, commonly referred to as disk drives, hard drives or HDDs. In addition to HDDs, the Company produces a broad range of data storage products including solid state drives (“SSDs”), solid state hybrid drives (“SSHDs”) and storage subsystems.

Hard disk drives are devices that store digitally encoded data on rapidly rotating disks with magnetic surfaces. Disk drives continue to be the primary medium of mass data storage due to their performance attributes, high quality and cost effectiveness. Complementing existing data center storage architecture, solid-state storage devices use integrated circuit assemblies as memory to store data, and most SSDs use NAND flash memory. In addition to HDDs and SSDs, SSHDs combine the features of SSDs and HDDs in the same unit, containing a high capacity hard disk drive and a smaller SSD acting as a cache to improve performance of frequently accessed data.

The Company's HDD products are designed for mission critical and nearline applications in enterprise servers and storage systems; edge compute/client compute applications, where its products are designed primarily for desktop and mobile computing; and edge non-compute/client non-compute applications, where its products are designed for a wide variety of end user devices such as portable external storage systems, surveillance systems, digital video recorders (“DVRs”), network-attached storage (“NAS”) and gaming consoles. The Company's SSD products mainly include serial attached SCSI ("SAS") and Non-Volatile Memory Express ("NVMe") SSDs.

The Company's cloud systems and solutions portfolio includes modular original equipment manufacturer (“OEM”) storage systems and scale-out storage servers.

Basis of Presentation and Consolidation

The consolidated financial statements include the accounts of the Company and all its wholly-owned and majority-owned subsidiaries, after elimination of intercompany transactions and balances.

The preparation of financial statements in accordance with U.S. generally accepted accounting principles also requires management to make estimates and assumptions that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. The methods, estimates and judgments the Company uses in applying its most critical accounting policies have a significant impact on the results the Company reports in its consolidated financial statements. Certain prior years amounts reported in the consolidated financial statements and notes thereto have been reclassified to conform to the current year’s presentation.

The Company operates and reports financial results on a fiscal year of52 or 53weeks ending on the Friday closest to June 30. Accordingly, fiscal years 2018, 2017 and 2016 were comprised of 52 weeks ended on June 29, 2018, June 30, 2017 and July 1, 2016, respectively. All references to years in these Notes to Consolidated Financial Statements represent fiscal years unless otherwise noted. Fiscal year 2019 will be comprised of 52 weeks and will end on June 28, 2019.

Summary of Significant Accounting Policies

Cash, Cash Equivalents and Short-Term Investments. The Company considers all highly liquid investments with a remaining maturity of 90 days or less at the time of purchase to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value. From time to time, the Company has short-term investments that are primarily comprised of money market funds, time deposits and certificates of deposits. The Company has classified its marketable securities as available-for-sale and they are stated at fair value with unrealized gains and losses included in Accumulated other comprehensive loss, which is a component of Shareholders' Equity. The Company evaluates the available-for sale securities in an unrealized loss position for other-than-temporary impairment. Realized gains and losses are included in Other, net on the Company's Consolidated Statements of Operations. The cost of securities sold is based on the specific identification method.

Restricted Cash and Investments. Restricted cash and investments represent cash and cash equivalents and investments that are restricted as to withdrawal or use for other than current operations.

Allowances for Doubtful Accounts.    The Company maintains an allowance for uncollectible accounts receivable based upon expected collectability. This reserve is established based upon historical trends, global macroeconomic conditions and an analysis of specific exposures. The provision for doubtful accounts is recorded as a charge to Marketing and administrative expense on the Company's Consolidated Statements of Operations.

Inventory.  The Company accounts for inventory in accordance with Accounting Standard Codification ("ASC") Topic 330, Inventory. During fiscal year 2018, the Company adopted Accounting Standard Update ("ASU") No. 2015-11, Inventory: Simplifying the Measurement of Inventory (ASC topic 330). Inventories are valued at the lower of cost (using the first-in, first-out method) and net realizable value. Net realizable value is based upon the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.

Property, Equipment and Leasehold Improvements.    Property, equipment and leasehold improvements are stated at cost. Equipment and buildings are depreciated using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated life of the asset or the remaining term of the lease. The costs of additions and substantial improvements to property, equipment and leasehold improvements, which extend the economic life of the underlying assets, are capitalized. The cost of maintenance and repairs to property, equipment and leasehold improvements is expensed as incurred.

Assessment of Goodwill and Other Long-lived Assets for Impairment. The Company accounts for goodwill in accordance with ASC Topic 350 ("ASC 350"), Intangibles - Goodwill and Other.The Company performs a qualitative assessment in the fourth quarter of each year, or more frequently if indicators of potential impairment exist, to determine if any events or circumstances exist, such as an adverse change in business climate or a decline in the overall industry that would indicate that it would more likely than not reduce the fair value of a reporting unit below its carrying amount, including goodwill. If it is determined in the qualitative assessment that the fair value of a reporting unit is more likely than not below its carrying amount, including goodwill, then the Company will perform a quantitative impairment test. The quantitative goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. Any excess in the carrying value of a reporting unit's goodwill over its fair value is recognized as an impairment loss, limited to the total amount of goodwill allocated to that reporting unit.

The Company tests other long-lived assets, including property, equipment and leasehold improvements and other intangible assets subject to amortization, for recoverability whenever events or changes in circumstances indicate that the carrying value of those assets may not be recoverable. The Company performs a recoverability test to assess the recoverability of an asset group. If the recoverability test indicates that the carrying value of the asset group is not recoverable, the Company will estimate the fair value of the asset group and the excess of the carrying value over the fair value is allocated pro rata to derive the adjusted carrying value of assets in the asset group. The adjusted carrying value of each asset in the asset group is not reduced below its fair value.

The Company tests other intangible assets not subject to amortization whenever events occur or circumstances change, such as declining financial performance, deterioration in the environment in which the entity operates or deteriorating macroeconomic conditions that have a negative effect on future expected earnings and cash flows that could affect significant inputs used to determine the fair value of the indefinite-lived intangible asset.

Investment in Debt Security and Payment-in-Kind (“PIK”) Income. The Company has debt investment in non-convertible preferred stock of K.K. Pangea. The Company determined the appropriate classification of such investment at the time of purchase and will re-evaluate such designation at each balance sheet date. The Company classified the investment as held-to-maturity as it has the positive intent and ability to hold the security until maturity. This held-to-maturity investment is carried at amortized cost and recorded as Investment in debt security on the Consolidated Balance Sheets.

Transaction costs incurred by the Company to acquire this investment are capitalized and amortized as a reduction of interest income on the Consolidated Statements of Operations over the respective term of the investment. The investment contains a PIK income provision, which represents contractual interest that is due at maturity, and is accrued and recorded as Interest income each reporting period and added to the carrying value of the Investment in debt security.

The Company assesses whether an other-than-temporary impairment loss on the debt security, including the accrued PIK income, has occurred due to a decline in fair value or other market conditions. If the fair value of the debt security is below amortized cost and it is more likely than not that the Company will not be able to recover the amortized cost bases before its stated maturity, the Company will record an other-than-temporary impairment charge to Other, net in the Consolidated Statements of Operations.

Derivative Financial Instruments. The Company applies the requirements of ASC Topic 815 ("ASC 815"), Derivatives and Hedging. ASC 815 requires that all derivatives be recorded on the balance sheet at fair value and establishes criteria for designation and effectiveness of hedging relationships. During fiscal year 2018, the Company early adopted ASU No. 2017-12, Derivatives and Hedging (ASC Topic 815) —Targeted Improvements to Accounting for Hedging Activities. The Company continues to exclude the change in forward points from the assessment of hedge effectiveness and recognizes the excluded component in Other, net in the Consolidated Statements of Operations. Foreign currency forward exchange contracts not designated as hedge instruments are used to economically hedge the foreign currency exposure in the value of an investment denominated in currency other than U.S. dollar. The Company recognizes the unrealized gains (losses) due to the changes in the fair value of these contracts in Other, net in the Consolidated Statements of Operations along with the foreign currency gains and losses on remeasurement of such investment.   

Establishment of Warranty Accruals.    The Company estimates probable product warranty costs at the time revenue is recognized. The Company generally warrants its products for a period of1 to 5years. The Company's warranty provision considers estimated product failure rates and trends (including the timing of product returns during the warranty periods), and estimated repair or replacement costs related to product quality issues, if any. The Company also exercises judgment in estimating its ability to sell certain repaired products. Should actual experience in any future period differ significantly from its estimates, the Company's future results of operations could be materially affected.

Revenue Recognition, Sales Returns and Allowances, and Sales Incentive Programs.    The Company's revenue recognition policy complies with ASC Topic 605 ("ASC 605"), Revenue Recognition. Revenue from sales of products, including sales to distribution customers, is generally recognized when title and risk of loss has passed to the buyer, which typically occurs upon shipment from the Company or third party's warehouse facilities, persuasive evidence of an arrangement exists, including a fixed or determinable price to the buyer, and when collectability is reasonably assured. Revenue from sales of products to certain direct retail customers and to customers in certain indirect retail channels is recognized on a sell-through basis.

The Company records estimated product returns at the time of shipment. The Company also estimates reductions to revenue for sales incentive programs, such as price protection, and volume incentives, and records such reductions when revenue is recorded. The Company establishes certain distributor and OEM sales programs aimed at increasing customer demand. For OEM sales, rebates are typically based on an OEM customer's volume of purchases from Seagate or other agreed upon rebate programs. For the distribution channel, these programs typically involve rebates related to a distributor's level of sales, order size, advertising or point of sale activity and price protection adjustments. The Company provides for these obligations at the time that revenue is recorded based on estimated requirements. Marketing development programs are recorded as a reduction to revenue.

Shipping and Handling.    The Company includes costs related to shipping and handling in Cost of revenue in the Consolidated Statements of Operations for all periods presented.

Restructuring Costs.     The Company records restructuring activities including costs for one-time termination benefits in accordance with ASC Topic 420 ("ASC 420"), Exit or Disposal Cost Obligations. The timing of recognition for severance costs accounted for under ASC 420 depends on whether employees are required to render service until they are terminated in order to receive the termination benefits. If employees are required to render service until they are terminated in order to receive the termination benefits, a liability is recognized ratably over the future service period. Otherwise, a liability is recognized when management has committed to a restructuring plan and has communicated those actions to employees. Employee termination benefits covered by existing benefit arrangements are recorded in accordance with ASC Topic 712, Nonretirement Postemployment Benefits. These costs are recognized when management has committed to a restructuring plan and the severance costs are probable and estimable.

Advertising Expense.    The cost of advertising is expensed as incurred. Advertising costs were approximately $28 million, $16 million and $31 million in fiscal years 2018, 2017 and 2016, respectively.

Share-Based Compensation.    The Company accounts for share-based compensation under the provisions of ASC Topic 718 (ASC 718), Compensation-Stock Compensation. During fiscal year 2018, the Company adopted ASU 2016-09, Stock Compensation—Improvements to Employee Share-Based Payment Accounting (ASC Topic 718). The Company has elected to apply the with-and-without method to assess the realization of related excess tax benefits. The Company also elected to continue to account for share-based compensation expense net of estimated forfeitures.

Accounting for Income Taxes. The Company accounts for income taxes pursuant to ASC Topic 740 ("ASC 740"), Income Taxes. During fiscal year 2018, the Company adopted ASU 2016-16, Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory (ASC Topic 740). In applying ASC 740, the Company makes certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of tax credits, recognition of income and deductions and calculation of specific tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for income tax and financial statement purposes, as well as tax liabilities associated with uncertain tax positions. The calculation of tax liabilities involves uncertainties in the application of complex tax rules and the potential for future adjustment of the Company’s uncertain tax positions by the Internal Revenue Service or other tax jurisdictions. If estimates of these tax liabilities are greater or less than actual results, an additional tax benefit or provision will result. The deferred tax assets the Company records each period depend primarily on the Company’s ability to generate future taxable income in the United States and certain non-U.S. jurisdictions. Each period, the Company evaluates the need for a valuation allowance for its deferred tax assets and, if necessary, adjusts the valuation allowance so that net deferred tax assets are recorded only to the extent the Company concludes it is more likely than not that these deferred tax assets will be realized. If the Company’s outlook for future taxable income changes significantly, the Company’s assessment of the need for, and the amount of a valuation allowance may also change.

Comprehensive Income. The Company presents comprehensive income in a separate statement. Comprehensive income is comprised of net income and other gains and losses affecting equity that are excluded from net income.

Foreign Currency Remeasurement and Translation.    The U.S. dollar is the functional currency for the majority of the Company's foreign operations. Monetary assets and liabilities denominated in foreign currencies are remeasured into the functional currency of the subsidiary at the balance sheet date. The gains and losses from the remeasurement of foreign currency denominated balances into the functional currency of the subsidiary are included in Other, net on the Company's Consolidated Statements of Operations. The Company’s subsidiaries that use the U.S. dollar as their functional currency remeasure monetary assets and liabilities at exchange rates in effect at the end of each period, and nonmonetary assets and liabilities at historical rates.

The Company had $3 million, $9 million and $3 million in remeasurement losses in fiscal years 2018, 2017 and 2016, respectively.

The Company translates the assets and liabilities of its non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period. Revenue and expenses for these subsidiaries are translated using rates that approximate those in effect during the period. Gains and losses from these translations are recognized in foreign currency translation included in Accumulated other comprehensive loss, which is a component of shareholders’ equity.

Concentrations

Concentration of Credit Risk.    The Company's customer base for disk drive products is concentrated with a small number of customers. The Company does not generally require collateral or other security to support accounts receivable. To reduce credit risk, the Company performs ongoing credit evaluations on its customers' financial condition. The Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of customers, historical trends and other information. Dell Inc. accounted for more than 10% of the Company's accounts receivable as of June 29, 2018 and June 30, 2017.

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents, investments and foreign currency forward exchange contracts. The Company mitigates concentrations of credit risk in its investments through diversifications, by investing in highly-rated securities or major multinational companies.

In entering into foreign currency forward exchange contracts, the Company assumes the risk that might arise from the possible inability of counterparties to meet the terms of their contracts. The counterparties to these contracts are major multinational commercial banks, and the Company has not incurred and does not expect any losses as a result of counterparty defaults.

Supplier Concentration.Certain of the raw materials, components and equipment used by the Company in the manufacture of its products are available from single-sourced vendors. Shortages could occur in these essential materials and components due to an interruption of supply or increased demand in the industry. If the Company were unable to procure certain materials, components or equipment at acceptable prices, it would be required to reduce its manufacturing operations, which could have a material adverse effect on its results of operations. In addition, the Company may make prepayments to certain suppliers or enter into minimum volume commitment agreements. Should these suppliers be unable to deliver on their obligations or experience financial difficulty, the Company may not be able to recover these prepayments.

Recently Issued Accounting Pronouncements

In May 2014, August 2015, April 2016, May 2016 and December 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09 (ASC Topic 606), Revenue from Contracts with Customers, ASU 2015-14 (ASC Topic 606) Revenue from Contracts with Customers, Deferral of the Effective Date, ASU 2016-10 (ASC Topic 606) Revenue from Contracts with Customers, Identifying Performance Obligations and Licensing, ASU 2016-12 (ASC Topic 606) Revenue from Contracts with Customers, Narrow-Scope Improvements and Practical Expedients, and ASU 2016-20 (ASC Topic 606) Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, respectively. ASC Topic 606 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. It also requires entities to disclose both quantitative and qualitative information that enable financial statements users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company is required to adopt the guidance in the first quarter of fiscal year 2019. This standard may be applied retrospectively to all prior periods presented, or retrospectively with a cumulative adjustment to retained earnings in the year of adoption (“modified retrospective transition approach”). The Company will adopt this standard in the first quarter of fiscal year 2019 utilizing the modified retrospective transition approach.

The Company has substantially completed its evaluation and expects the adoption of the new standard will result in the recognition of revenue when the products are delivered (sell-in basis) to certain direct retail customers and customers in certain indirect retail channels which are currently being recognized on a sell-through basis. Accordingly, the Company will estimate appropriate accruals for the variable consideration (e.g. rebates) related to customer incentives on these arrangements. On the date of initial adoption, the Company will remove the deferred income that would have been subsequently recognized on a sell-through basis and record estimates of the accruals for variable consideration through a cumulative adjustment to accumulated deficit. The Company believes that these changes will not have a material impact on the Company’s consolidated financial statements and internal controls over financial reporting.

In January 2016, the FASB issued ASU 2016-01 (ASC Subtopic 825-10), Financial Instruments—Overall Recognition and Measurement of Financial Assets and Financial Liabilities, as amended by ASU 2018-03, Financial Instruments—Overall: Technical Correction and Improvements, issued in February 2018. The amendments in these ASUs require entities to measure all investments in equity securities at fair value with changes recognized through net income. This requirement does not apply to investments that qualify for the equity method of accounting, to those that result in consolidation of the investee, or for which the entity meets a practicability exception to fair value measurement. Additionally, the amendments eliminate certain disclosure requirements related to financial instruments measured at amortized cost and add disclosures related to the measurement categories of financial assets and financial liabilities. The Company is required to adopt the guidance in the first quarter of fiscal year 2019. Early adoption is permitted for only certain portions of the ASU. The Company expects to elect the measurement alternative for measurement of equity investments, defined as cost, less impairments, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment in the same issuer (the “Price Changes”) until the equity investments’ fair value becomes readily determinable. The amount of the impact to equity investments will depend on any Price Changes observed after adoption in the first quarter of fiscal year 2019.

In February 2016 and July 2018, the FASB issued ASU 2016-02 (ASC Topic 842), Leases, ASU 2018-10, Codification Improvements to Topic 842, Leases, ASU 2018-11, Leases (ASC Topic 842), Targeted Improvements, respectively. ASC Topic 842 amends a number of aspects of lease accounting, including requiring lessees to recognize operating leases with a term greater than one year on their balance sheet as a right-of-use asset and corresponding lease liability, measured at the present value of the lease payments. The Company is required to adopt this guidance in the first quarter of fiscal year 2020. Early adoption is permitted. The Company is in the process of assessing the impact of these ASUs on its consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13 (ASC Topic 326), Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments. This ASU amends the requirement on the measurement and recognition of expected credit losses for financial assets held. The Company is required to adopt this guidance in the first quarter of fiscal year 2021. Early adoption in the first quarter of fiscal year 2020 is permitted. The Company is in the process of assessing the impact of this ASU on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01 (ASC Topic 805), Business Combinations: Clarifying the Definition of a Business. The amendments in this ASU change the definition of a business to assist with evaluating when a set of transferred assets and activities is a business. The Company plans to adopt the guidance in the first quarter of fiscal year 2019. The Company does not expect the adoption of this ASU will have a material impact on its consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09 (ASC Topic 718), Stock Compensation: Scope of Modification Accounting. The amendments in this ASU provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The Company plans to adopt the guidance in the first quarter of fiscal year 2019. The Company does not expect the adoption of this ASU will have a material impact on its consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02 (ASC Topic 220), Income Statement—Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU was issued following the enactment of the U.S. Tax Cuts and Jobs Act of 2017 (the “Tax Act”) and permits entities to elect a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. The Company is required to adopt the guidance in the first quarter of fiscal year 2020. Early adoption is permitted. The Company is in the process of assessing the impact of this ASU on its consolidated financial statements.

Recently Adopted Accounting Pronouncements

In July 2015, the FASB issued ASU 2015-11 (ASC Topic 330), Inventory: Simplifying the Measurement of Inventory. The amendments in this ASU require inventory measurement at the lower of cost and net realizable value. This ASU became effective and was adopted by the Company in the September 2017 quarter on a prospective basis. The adoption of this guidance had no material impact on the Company’s consolidated financial statements and disclosures.

In March 2016, the FASB issued ASU 2016-09 (ASC Topic 718), Stock Compensation—Improvements to Employee Share-Based Payment Accounting. The amendments in this ASU are intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax consequences, classification on the consolidated statement of cash flows and treatment of forfeitures. This ASU became effective and was prospectively adopted by the Company in the September 2017 quarter. Upon adoption, excess tax benefits or deficiencies from share-based award activity are reflected in the Consolidated Statements of Operations as a component of the provision for income taxes, whereas they previously were recognized in the Shareholders’ equity in the Consolidated Balance Sheets. The Company also elected to continue to account for share-based compensation expense net of estimated forfeitures. The adoption of this ASU resulted in an increase in deferred tax assets relating to net operating losses of approximately$0.6 billion, offset by an equivalent increase in the valuation allowance with no impact to retained earnings. The adoption of this guidance had no material impact on the Company’s consolidated financial statements and disclosures.

In October 2016, the FASB issued ASU 2016-16 (ASC Topic 740), Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory. The amendments in this ASU require the recognition of the income tax consequences for intra-entity transfers of assets other than inventory when the transfer occurs. The Company elected to early adopt this ASU in the September 2017 quarter on a modified retrospective basis with no material impact on the Company’s consolidated financial statements and disclosures.

In August 2017, the FASB issued ASU 2017-12 (ASC Topic 815), Derivatives and Hedging, Targeted Improvements to Accounting for Hedging Activities. The amendments in this ASU simplify the application of hedge accounting guidance and more closely aligning financial reporting for hedging relationships with economic results of an entity's risk management activities. The Company early adopted this ASU in the June 2018 quarter. The adoption of this guidance had no material impact on the Company's consolidated financial statements and disclosures.

Short-Term Borrowings

The credit agreement entered into by the Company and its subsidiary Seagate HDD Cayman on January 18, 2011 and subsequently amended (the "Revolving Credit Facility") provides the Company with a$700 millionsenior secured revolving credit facility. The term of the Revolving Credit Facility is through January 15, 2020, provided that if the Company does not have Investment Grade Ratings (as defined in the Revolving Credit Facility) on August 15, 2018, then the maturity date will be August 16, 2018 unless certain extension conditions have been satisfied. The loans made under the Revolving Credit Facility will bear interest at a rate of LIBOR plus a variable margin that will be determined based on the corporate credit rating of the Company. The Company and certain of its material subsidiaries fully and unconditionally guarantee the Revolving Credit Facility. The Revolving Credit Facility is available for cash borrowings, subject to compliance with certain covenants and other customary conditions to borrowing, and for the issuance of letters of credit up to a sub-limit of $75 million.

The Revolving Credit Facility, as amended, includes three financial covenants: (1) minimum cash, cash equivalents and marketable securities, (2) a fixed charge coverage ratio and (3) a net leverage ratio. On April 27, 2016, the Revolving Credit Agreement was amended in order to increase the allowable net leverage ratio to allow for higher net leverage levels. The Company was in compliance with the modified covenants as of June 29, 2018and expects to be in compliance for the next 12 months.

As of June 29, 2018, noborrowings had been drawn or letters of credit utilized under the Revolving Credit Facility.

On December 22, 2017, the Tax Act was enacted into law in the United States. The Tax Act significantly revises U.S. corporate income tax law by, among other things, lowering U.S. corporate income tax rates from 35% to 21%, implementing a territorial tax system, and imposing a one-time transition tax on deemed repatriated earnings of non-U.S. subsidiaries.

Pursuant to SEC Staff Accounting Bulletin (“SAB”) 118 (regarding the application of ASC 740 associated with the enactment of the Tax Act), the Company recorded an adjusted tax expense of approximately $204 million during fiscal year 2018, to re-measure its net U.S. deferred tax assets at the newly enacted 21% income tax rate. This tax expense increased the Company’s effective tax rate by approximately 14%. The Company also does not expect the one-time transition tax to have a material impact on the Company’s consolidated financial statements due to an overall accumulated earnings deficit in its non-U.S. subsidiaries for which the transition tax applies. The Company has considered SAB 118 and believes the accounting under ASC 740 for the change to the U.S. statutory tax rate to its deferred tax balances and the one-time transition tax under the Tax Act is complete and appropriately reflected in the financial statements during fiscal year 2018.

For all other provisions relating to the Tax Act, the Company continues to evaluate the impact of the Tax Act’s various highly complex domestic and international provisions. The other U.S. tax changes, including limitations on various business deductions such as executive compensation under Internal Revenue Code §162(m), are not expected to impact the Company’s tax expense in the short-term due to the Company’s large net operating loss and tax credit carryovers and associated valuation allowance. The Tax Act’s new international rules, including Global Intangible Low-Taxed Income (“GILTI”), Foreign Derived Intangible Income (“FDII”), and Base Erosion Anti-Avoidance Tax (“BEAT”) are generally effective in tax years beginning after December 31, 2017. These provisions are not expected to have a material impact on the Company’s consolidated financial statements. However, these preliminary assessments and analyses are provisional and are subject to change as additional interpretive guidance is issued. The Company will complete its analysis within fiscal year 2019 which is consistent with the guidance provided in SAB 118.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company recorded an adjustment for its U.S. deferred income taxes as of June 29, 2018 to reflect the reduction in the U.S. statutory tax rate from 35% to 21% resulting from the Tax Act. The significant components of the Company's deferred tax assets and liabilities were as follows:

	Fiscal Years Ended

During fiscal year 2018, the Company adopted two accounting pronouncements with tax implications - ASU 2016-09 (related to employee share-based payment accounting)andASU 2016-16 (related to intra-entity transfers of assets). There was no material impact to the Company's financial statements as a result of the adoptions. The adoption of ASU 2016-09 resulted in an increase in gross deferred tax assets relating to net operating losses of approximately $0.6 billion offset by an equivalent increase in valuation allowance. For additional detail about both ASU’s, please refer to Note 1. Basis of Presentation and Summary of Significant Accounting Policies.

The deferred tax asset valuation allowance increased by $255 million in fiscal year 2018, mainly due to the adoption of ASC 2016-09 offset by the U.S. corporate tax rate reduction as a result of the Tax Act, and decreased by $18 million in fiscal year 2017.

At June 29, 2018, the Company recorded $410 millionof net deferred tax assets. The realization of most of these deferred tax assets is primarily dependent on the Company's ability to generate sufficient U.S. and certain non-U.S. taxable income in future periods. Although realization is not assured, the Company's management believes it is more likely than not that these deferred tax assets will be realized. The amount of deferred tax assets considered realizable, however, may increase or decrease in subsequent periods when the Company re-evaluates the underlying basis for its estimates of future U.S. and certain non-U.S. taxable income.

At June 29, 2018, the Company had U.S. federal, state and non-U.S. tax net operating loss carryforwards of approximately $3.2 billion, $1.8 billion and $54 million, respectively, which will expire at various dates beginning in fiscal year 2019, if not utilized. Net operating loss carryforwards of approximately$42 million are scheduled to expire in fiscal year 2019. At June 29, 2018, the Company had U.S. federal and state tax credit carryforwards of $485 million and $114 million, respectively, which will expire at various dates beginning in fiscal year 2019, if not utilized.

As of June 29, 2018, approximately $501 million and $99 millionof the Company's total U.S. net operating loss and tax credit carryforwards, respectively, are subject to annual limitations ranging from$1 million to $45 million pursuant to U.S. tax law.

For purposes of the reconciliation between the provision for income taxes at the statutory rate and the effective tax rate, the Irish statutory rate of 25% was applied as follows:

	Fiscal Years Ended

A substantial portion of the Company's operations in Malaysia, Singapore and Thailand operate under various tax incentive programs, which expire in whole or in part at various dates through 2027. Certain tax incentives may be extended if specific conditions are met. The net impact of these tax incentive programs was to increase the Company's net income by approximately$269 million in fiscal year 2018 ($0.92 per share, diluted), to increase the Company's net income by approximately $163 million in fiscal year 2017 ($0.54 per share, diluted), and to increase the Company's net income by approximately $67 million in fiscal year 2016 ($0.22 per share, diluted).

The Company consists of an Irish tax resident parent holding company with various U.S. and non-U.S. subsidiaries that operate in multiple non-Irish taxing jurisdictions. The amount of temporary differences (including undistributed earnings) related to outside basis differences in the stock of non-Irish resident subsidiaries considered indefinitely reinvested outside of Ireland for which Irish income taxes have not been provided as ofJune 29, 2018, was approximately $1.8 billion. If such amounts were remitted to Ireland as a dividend, it is likely that tax at 25%, or approximately $450 million would result.

As of June 29, 2018 and June 30, 2017, the Company had approximately $60 million and $74 million, respectively, of unrecognized tax benefits excluding interest and penalties. The amount of unrecognized tax benefits that, if recognized, would impact the effective tax rate are $60 million and $74 million as of June 29, 2018 and June 30, 2017, respectively, subject to certain future valuation allowance offsets.

The following table summarizes the activity related to the Company's gross unrecognized tax benefits:

It is the Company's policy to include interest and penalties related to unrecognized tax benefits in the provision for income taxes on the Consolidated Statements of Operations. During fiscal year 2018, the Company recognized net income tax benefit for interest and penalties of $2 million, as compared to net income tax benefit of $1 million during fiscal year 2017, and income tax benefit of $8 million during fiscal year 2016. As of June 29, 2018, the Company had $2 million of accrued interest and penalties related to unrecognized tax benefits compared to $4 million in fiscal year 2017.

During the 12 months beginning June 30, 2018, the Company expects that its unrecognized tax benefits could be reduced by approximately $18 million as a result of the expiration of certain statutes of limitation.

The Company is required to file U.S. federal, U.S. state and non-U.S. income tax returns. The Company is no longer subject to examination of its U.S. federal income tax returns for years prior to fiscal year 2015. With respect to U.S. state and non-U.S. income tax returns, the Company is generally no longer subject to tax examination for years ending prior to fiscal year 2007.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

The Company is exposed to foreign currency exchange rate, interest rate, and to a lesser extent, equity market risks relating to its ongoing business operations. From time to time, the Company enters into cash flow hedges in the form of foreign currency forward exchange contracts in order to manage the foreign currency exchange rate risk denominated in foreign currencies. The Company’s accounting policies for these instruments are based on whether the instruments are classified as designated or non-designated hedging instruments. The Company records all derivatives in the Consolidated Balance Sheets at fair value. The changes in the fair value of highly effective designated cash flow hedges are recorded in Accumulated other comprehensive loss until the hedged item is recognized in earnings. Derivatives that are not designated as hedging instruments or are not assessed to be highly effective are adjusted to fair value through earnings. The amount of net unrealized gain on cash flow hedges was less than $1 million as of June 29, 2018. The Company had no outstanding cash flow hedges as of June 30, 2017.

The Company de-designates its cash flow hedges when the forecasted hedged transactions affects earnings or it is probable the forecasted hedged transactions will not occur in the initially identified time period. At such time, the associated gains and losses deferred in Accumulated other comprehensive lossare reclassified immediately into earnings and any subsequent changes in the fair value of such derivative instruments are immediately reflected in earnings. The Company did not recognize any material amounts related to the loss of hedge designation on discontinued cash flow hedges during fiscal years 2018, 2017 and 2016.

Other derivatives not designated as hedging instruments consist of foreign currency forward exchange contracts that the Company uses to hedge the foreign currency exposure on the investment in debt security denominated in currency other than the U.S. dollar. The Company recognizes gains and losses on these contracts, as well as the related costs in Other, net on the Consolidated Statement of Operations along with foreign currency gains and losses on investment in debt security.

The following tables show the total notional value of the Company's outstanding foreign currency forward exchange contracts as of June 29, 2018. All these foreign currency forward contracts mature within 12 months.

The Company did not have outstanding foreign currency forward exchange contracts as of June 30, 2017

The Company is subject to equity market risks due to changes in the fair value of the notional investments selected by its employees as part of its Non-qualified Deferred Compensation Plan—the Seagate Deferred Compensation Plan (the “SDCP”). In fiscal year 2014, the Company entered into a Total Return Swap (“TRS”) in order to manage the equity market risks associated with the SDCP liabilities. The Company pays a floating rate, based on LIBOR plus an interest rate spread, on the notional amount of the TRS. The TRS is designed to substantially offset changes in the SDCP liability due to changes in the value of the investment options made by employees. As ofJune 29, 2018, the notional investments underlying the TRS amounted to$114 million. The contract term of the TRS is through January 2019 and is settled on a monthly basis, therefore limiting counterparty performance risk. The Company did not designate the TRS as a hedge. Rather, the Company records all changes in the fair value of the TRS to earnings to offset the market value changes of the SDCP liabilities.

The following tables show the Company's derivative instruments measured at gross fair value as reflected in the Consolidated Balance Sheet as ofJune 29, 2018:

As of June 30, 2017, the Company did not have outstanding foreign currency forward exchange contracts and the gross fair value of the TRS reflected in the Consolidated Balance Sheets is immaterial.

The amount of gain or loss recognized in the Consolidated Statement of Comprehensive Income on derivatives designated as cash flow hedges was less than $1 million as of June 29, 2018.

Fair Value Disclosures [Abstract]

Fair Value

Fair Value

Measurement of Fair Value

Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

Fair Value Hierarchy

A fair value hierarchy is based on whether the market participant assumptions used in determining fair value are obtained from independent sources (observable inputs) or reflects the Company's own assumptions of market participant valuation (unobservable inputs). A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of inputs that may be used to measure fair value are:

Level 1 - Quoted prices in active markets that are unadjusted and accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 - Quoted prices for identical assets and liabilities in markets that are inactive; quoted prices for similar assets and liabilities in active markets or financial instruments for which significant inputs are observable, either directly or indirectly; or

Level 3 - Prices or valuations that require inputs that are both unobservable and significant to the fair value measurement.

The Company considers an active market to be one in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis, and views an inactive market as one in which there are few transactions for the asset or liability, the prices are not current, or price quotations vary substantially either over time or among market makers. Where appropriate, the Company's or the counterparty's non-performance risk is considered in determining the fair values of liabilities and assets, respectively.

Items Measured at Fair Value on a Recurring Basis

The Company classifies items in Level 1 if the financial assets consist of securities for which quoted prices are available in an active market.

The Company classifies items in Level 2 if the financial asset or liability is valued using observable inputs. The Company uses observable inputs including quoted prices in active markets for similar assets or liabilities. Level 2 assets include: agency bonds, corporate bonds, commercial paper, municipal bonds, U.S. Treasuries, time deposits and certificates of deposit. These debt investments are priced using observable inputs and valuation models which vary by asset class. The Company uses a pricing service to assist in determining the fair values of all of its cash equivalents and short-term investments. For the cash equivalents and short-term investments in the Company's portfolio, multiple pricing sources are generally available. The pricing service uses inputs from multiple industry standard data providers or other third party sources and various methodologies, such as weighting and models, to determine the appropriate price at the measurement date. The Company corroborates the prices obtained from the pricing service against other independent sources and, as ofJune 29, 2018, has not found it necessary to make any adjustments to the prices obtained. The Company's derivative financial instruments are also classified within Level 2. The Company's derivative financial instruments consist of foreign currency forward exchange contracts and the TRS. The Company recognizes derivative financial instruments in its consolidated financial statements at fair value. The Company determines the fair value of these instruments by considering the estimated amount it would pay or receive to terminate these agreements at the reporting date.

As of June 29, 2018 and June 30, 2017, the Company had no Level 3 assets or liabilities measured at fair value on a recurring basis.

Items Measured at Fair Value on a Non-Recurring Basis

From time to time, the Company enters into certain strategic investments for the promotion of business and strategic objectives. These strategic investments primarily include cost basis investments representing those where the Company does not have the ability to exercise significant influence as well as equity method investments representing those where the Company does have the ability to exercise significant influence but does not have control. These investments are included in Other assets, net in the Consolidated Balance Sheets, and are periodically analyzed to determine whether or not there are indicators of impairment. The carrying value of the Company's strategic investments atJune 29, 2018 and June 30, 2017 totaled $118 million and $125 million, respectively, and consisted primarily of privately held equity securities without a readily determinable fair value.

During the fiscal years 2018, 2017 and 2016, the Company determined that certain of its equity investments accounted for under the cost method were other-than-temporarily impaired, and recognized charges of$11 million, $25 million and $13 million, respectively, in order to write down the carrying amount of the investments to its estimated fair value. Since there was no active market for the equity securities of the investee, the Company estimated fair value of the investee by analyzing the underlying cash flows and future prospects of the investee. These amounts were recorded in Other, net in the Consolidated Statements of Operations.

As of June 30, 2017, the Company had$77 million of held for sale land and buildings (collectively, the "Properties") primarily in Asia included in Other current assets on the Consolidated Balance Sheet. The respective Properties to be sold met the criteria to be classified as held for sale in fiscal year 2017. Depreciation related to the Properties ceased as of the date these were determined to be held for sale. During fiscal year 2017, the Company recorded impairment charges of $35 millionin order to write down the carrying amount of such properties to their estimated fair values less costs to sell. The impairment charges were recorded in Operating expenses in the Consolidated Statements of Operations. During fiscal year 2018, the Company completed the sale of certain of these properties and recorded a gain of approximately$25 million, which was included in Restructuring and other, net in the Consolidated Statements of Operations. As of June 29, 2018, the Company had one Property held at $26 million, that continues to be held-for-sale and included in Other current assets on the Consolidated Balance Sheet. No impairment charge was recorded in fiscal year 2018.The fair value of the Property was measured using inputs such as comparable market data for similar land sale transactions adjusted for differences in comparable properties to derive the estimated fair value of the subject property and the cost approach valuation techniques for building as part of the analysis. The fair value measurement was categorized as Level 3 as significant unobservable inputs were used in the valuation analysis.

Other Fair Value Disclosures

The Company's investment in debt security, classified as held-to-maturity, represents shares of non-convertible preferred stock of K.K. Pangea for the acquisition of Toshiba Memory Corporation by a consortium of investors led by Bain Capital Private Equity. This debt security has a maturity date of six years and is classified as Investment in debt security on the Company's Consolidated Balance Sheet. The debt security is recorded at amortized cost and its fair value approximates the carrying value at June 29, 2018. The fair value was determined utilizing Level 2 inputs such as discount rates and yield terms of similar types of securities issued by comparable companies.

The Company's debt is carried at amortized cost. The fair value of the Company's debt is derived using the closing price of the same debt instruments as of the date of valuation, which takes into account the yield curve, interest rates and other observable inputs. Accordingly, these fair value measurements are categorized as Level 2. The following table presents the fair value and amortized cost of the Company's debt in order of maturity:

Ordinary shares - Holders of ordinary shares are entitled to receive dividends when and as declared by the Company's board of directors (the "Board of Directors"). Upon any liquidation, dissolution, or winding up of the Company, after required payments are made to holders of preferred shares, any remaining assets of the Company will be distributed ratably to holders of the preferred and ordinary shares. Holders of shares are entitled toone vote per shareon all matters upon which the ordinary shares are entitled to vote, including the election of directors.

Preferred shares - The Company may issue preferred shares in oneor more series, up to the authorized amount, without shareholder approval. The Board of Directors is authorized to establish from time to time the number of shares to be included in each series, and to fix the rights, preferences and privileges of the shares of each wholly unissued series and any of its qualifications, limitations or restrictions. The Board of Directors can also increase or decrease the number of shares of a series, but not below the number of shares of that series then outstanding, without any further vote or action by the shareholders.

The Board of Directors may authorize the issuance of preferred shares with voting or conversion rights that could harm the voting power or other rights of the holders of the ordinary shares. The issuance of preferred shares, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in control of the Company and might harm the market price of its ordinary shares and the voting and other rights of the holders of ordinary shares.

Share-based Compensation

Share-based Compensation

Share-Based Compensation Plans

The Company's share-based compensation plans have been established to promote the Company's long-term growth and financial success by providing incentives to its employees, directors and consultants through grants of share-based awards. The provisions of the Company's share-based benefit plans, which allow for the grant of various types of equity-based awards, are also intended to provide greater flexibility to maintain the Company's competitive ability to attract, retain and motivate participants for the benefit of the Company and its shareholders.

Seagate Technology plc 2012 Equity Incentive Plan (the “EIP”). On October 26, 2011, the shareholders approved the EIP and authorized the issuance of up to a total of27.0 million ordinary shares, par value $0.0001 per share, plus any shares remaining available for grant under the Seagate Technology plc 2004 Share Compensation Plan (the "SCP") as of the effective date of the EIP (which was equal to11.0 millionordinary shares as of the effective date of the EIP and which will increase by such additional number of shares as will be returned to the share reserve in respect of awards previously granted under the SCP) (together, the “Share Reserve”). On October 22, 2014, the shareholders authorized the issuance from the EIP of an additional 25 million ordinary shares, par value $0.0001 per share. Any shares that are subject to options or share appreciation rights granted under the EIP will be counted against the Share Reserve as one share for every one share granted, and any shares that are subject to restricted share bonus awards, restricted share units, performance share bonus awards or performance share awards (collectively, “Full-Value Share Awards”) will generally be counted against the Share Reserve as two and five-tenths shares for every one share granted. On October 19, 2016, the shareholders authorized the issuance from the EIP of an additional 7.5 million ordinary shares, par value $0.0001 per share. As of June 29, 2018, there were approximately 25.7 millionordinary shares available for issuance under the EIP.

Dot Hill Systems 2009 Equity Incentive Plan (the "DHEIP"). Seagate Technology plc acquired the Dot Hill Systems 2009 Equity Incentive Plan effective October 6, 2015. The Company assumed the remaining authorized but unused share reserve of approximately 2 million shares, based on the conversion ratio, from the DHEIP on the acquisition date. Any shares that are subject to options or share appreciation rights granted under the DHEIP will be counted against the Share Reserve as one share for every one share granted, and any shares that are subject to restricted share bonus awards, restricted share units, performance share bonus awards or performance share awards (collectively, “Full-Value Share Awards”) will generally be counted against the Share Reserve as one and five-tenths shares for every one share granted. As ofJune 29, 2018, there were approximately 1 million ordinary shares available for issuance under the DHEIP.

Seagate Technology plc Employee Stock Purchase Plan (the "ESPP").  There are 60.0 million ordinary shares authorized to be issued under the ESPP. The ESPP consists of a six-month offering period with a maximum issuance of 1.5 million ordinary shares per offering period. The ESPP permits eligible employees to purchase ordinary shares through payroll deductions generally at 85% of the fair market value of the ordinary shares. As of June 29, 2018, there were approximately 12.8 million ordinary shares available for issuance under the ESPP.

Equity Awards

Full-Value Share Awards (e.g. restricted share units, "RSU") generally vest over a period of three to fouryears, with cliff vesting of a portion of each award occurring annually, subject to continuous employment with the Company through the vesting date. Options generally vest as follows: 25%of the options will vest on the first anniversary of the vesting commencement date and the remaining75%will vest ratably each month thereafter over the next36 months. Options granted under the EIP and SCP have an exercise price equal to the fair market value of the Company's ordinary shares on the grant date. Fair market value is defined as the closing price of the Company's ordinary shares on NASDAQ on the grant date.

The Company granted awards of performance-based share units ("PSU") to its senior executive officers under the SCP and the EIP where vesting is subject to both the continued employment of the participant by the Company and the achievement of certain performance goals established by the Compensation Committee of the Company's Board of Directors, including market-based performance goals. A single PSU represents the right to receive a single ordinary share of the Company. During fiscal years2018, 2017 and 2016, the Company granted 0.4 million, 0.6 million and 0.4 million PSUs, respectively, where performance is measured based on a three-year average return on invested capital ("ROIC") goal and a relative total shareholder return ("TSR") goal, which is based on the Company's ordinary shares measured against a benchmark TSR of a peer group over the same three-year period (the "TSR/ROIC" awards). These awards vest after the end of the performance period ofthree yearsfrom the grant date. A percentage of these units may vest only if at least the minimum ROIC goal is met regardless of whether the TSR goal is met. The number of share units to vest will range from0% to 200%of the targeted units. In evaluating the fair value of these units, the Company used a Monte Carlo simulation on the grant date, taking the market-based TSR goal into consideration. Compensation expense related to these units is only recorded in a period if it is probable that the ROIC goal will be met, and it is to be recorded at the expected level of achievement.

The Company also granted 0.2 million, 0.2 million and 0.2 million PSUs during fiscal years 2018, 2017 and 2016, respectively, to its senior executive officers which are subject to a performance goal related to the Company's adjusted earnings per share (the "AEPS" awards). These awards have a maximum seven-year vesting period, with 25%annual vesting starting on the first anniversary of the grant date. If the performance goal is not achieved, vesting is delayed to a following year in which the AEPS goal is achieved. Any unvested awards from prior years may vest cumulatively in a future year within theseven-year vesting period if the annual AEPS goal is achieved during a subsequent year. If the AEPS goal has not been met by the end of the seven year period, any unvested shares will be forfeited.

Determining Fair Value of Seagate Technology Stock Plans

Valuation and amortization method - The Company estimates the fair value of stock options, RSU and performance awards subject to an AEPS condition granted using the Black-Scholes-Merton valuation model and a single share award approach. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period or the remaining service (vesting) period.

Expected Term - Expected term represents the period that the Company's share-based awards are expected to be outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual terms of the share-based awards, vesting schedules and expectations of future employee behavior as influenced by changes to the terms of its share-based awards.

Expected Volatility - The Company uses a combination of the implied volatility of its traded options and historical volatility of its share price.

Expected Dividend - The Black-Scholes-Merton valuation model calls for a single expected dividend yield as an input. The dividend yield is determined by dividing the expected per share dividend during the coming year by the grant date share price. The expected dividend assumption is based on the Company's current expectations about its anticipated dividend policy. Also, because the expected dividend yield should reflect marketplace participants' expectations, the Company does not incorporate changes in dividends anticipated by management unless those changes have been communicated to or otherwise are anticipated by marketplace participants.

Risk-Free Interest Rate - The Company bases the risk-free interest rate used in the Black-Scholes-Merton valuation model on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term. Where the expected term of the Company's share-based awards do not correspond with the terms for which interest rates are quoted, the Company performed a straight-line interpolation to determine the rate from the available term maturities.

The fair value of the Company's shares related to options and RSU granted to employees, shares issued from the ESPP and PSUs subject to TSR/ROIC or AEPS conditions for fiscal years2018, 2017 and 2016 were estimated using the following assumptions:

Share-based Compensation Expense

The Company recorded $112 million, $137 million and $120 million of share-based compensation during fiscal years 2018, 2017 and 2016, respectively. Management has made an estimate of expected forfeitures and is recognizing compensation costs only for those equity awards expected to vest. When estimating forfeitures, the Company considers voluntary termination behavior as well as analysis of actual forfeited awards.

Stock Option Activity

The Company issues new ordinary shares upon exercise of stock options. The following is a summary of option activities:

Options	Number of Shares		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term	Aggregate Intrinsic Value
	(In millions)				(In years)	(Dollars in millions)
Outstanding at June 30, 2017	5.7		$	39.24	5.0	$22
Granted	1.4		$	33.67
Exercised	(1.8	)	$	32.66
Forfeitures	(1.0	)	$	38.61
Expirations	(0.3	)	$	54.18
Outstanding at June 29, 2018	4.0		$	39.00	5.0	$72
Vested and expected to vest at June 29, 2018	3.9		$	39.10	5.0	$70
Exercisable at June 29, 2018	1.4		$	44.26	4.0	$19

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted price of the Company's ordinary shares for the options that were in-the-money at June 29, 2018. During fiscal years 2018, 2017 and 2016, the aggregate intrinsic value of options exercised under the Company's stock option plans was $34 million, $29 million and $44 million, respectively, determined as of the date of option exercise. The aggregate fair value of options vested during fiscal years 2018, 2017 and 2016 were approximately $12 million, $15 million and $18 million, respectively.

At June 29, 2018, the total compensation cost related to options granted to employees but not yet recognized was approximately $16 million, net of estimated forfeitures of approximately $1 million. This cost is being amortized on a straight-line basis over a weighted-average remaining term of approximately 2.6 years and will be adjusted for subsequent changes in estimated forfeitures.

Nonvested Awards Activity

The following is a summary of nonvested award activities which do not contain a performance condition:

Nonvested Awards	Number of Shares		Weighted- Average Grant- Date Fair Value
	(In millions)
Nonvested at June 30, 2017	5.2		$	35.75
Granted	2.7		$	26.69
Forfeitures	(0.7	)	$	34.69
Vested	(2.0	)	$	36.71
Nonvested at June 29, 2018	5.2		$	30.74

At June 29, 2018, the total compensation cost related to nonvested awards granted to employees but not yet recognized was approximately $105 million, net of estimated forfeitures of approximately $9 million. This cost is being amortized on a straight-line basis over a weighted-average remaining term of 2.5 years and will be adjusted for subsequent changes in estimated forfeitures. The aggregate fair value of nonvested awards vested during fiscal years 2018, 2017 and 2016 were approximately $76 million, $73 million and $102 million, respectively.

Performance Awards

The following is a summary of nonvested award activities which contain a performance condition:

Performance Awards	Number of Shares		Weighted- Average Grant- Date Fair Value
	(In millions)
Performance units at June 30, 2017	1.5		$	41.88
Granted	0.5		$	26.28
Forfeitures	(0.5	)	$	40.84
Vested	(0.3	)	$	48.02
Performance units at June 29, 2018	1.2		$	33.34

At June 29, 2018, the total compensation cost related to performance awards granted to employees but not yet recognized was approximately $23 million, net of estimated forfeitures of approximately $3 million. This cost is being amortized on a straight-line basis over a weighted-average remaining term of 1.50 years.

ESPP

During fiscal years 2018, 2017 and 2016, the aggregate intrinsic value of shares purchased under the Company's ESPP was approximately $31 million, $24 million and $12 million, respectively. At June 29, 2018, the total compensation cost related to options to purchase the Company's ordinary shares under the ESPP but not yet recognized was approximately $1.4 million. This cost will be amortized on a straight-line basis over a weighted-average period of approximately one month. During fiscal year 2018, the Company issued 2.0 million ordinary shares with a weighted-average exercise price of $28.19 per share.

Tax-Deferred Savings Plan

The Company has a tax-deferred savings plan, the Seagate 401(k) Plan (the "40l(k) plan"), for the benefit of qualified employees. The 40l(k) plan is designed to provide employees with an accumulation of funds at retirement. Qualified employees may elect to make contributions to the 401(k) plan on a bi-weekly basis. Pursuant to the 401(k) plan, the Company matches 50% of employee contributions, up to 6% of compensation, subject to maximum annual contributions of $6,000 per participating employee. During fiscal years 2018, 2017 and 2016, the Company made matching contributions of $16 million, $18 million and $19 million, respectively.

Deferred Compensation Plan

On January 1, 2001, the Company adopted the SDCP for the benefit of eligible employees. This plan is designed to permit certain discretionary employer contributions, in excess of the tax limits applicable to the 401(k) plan and to permit employee deferrals in excess of certain tax limits. During fiscal year 2014, the Company entered into a TRS in order to manage the equity market risks associated with the SDCP liabilities. See Note 8. Derivative Financial Instruments contained in this report for additional information about the TRS.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share is computed by dividing income available to shareholders by the weighted-average number of shares outstanding during the period. Diluted earnings per share is computed by dividing income available to shareholders by the weighted-average number of shares outstanding during the period and the number of additional shares that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding options, unvested restricted stock units and performance-based share units and shares to be purchased under the Employee Stock Purchase Plan ("ESPP"). The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method. Under the treasury stock method, an increase in fair market value of the Company’s share price can result in a greater dilutive effect from potentially dilutive securities. The following table sets forth the computation of basic and diluted net income per share attributable to the shareholders of the Company:

Legal, Environmental and Other Contingencies

Legal, Environmental and Other Contingencies

The Company assesses the probability of an unfavorable outcome of all its material litigation, claims, or assessments to determine whether a liability had been incurred and whether it is probable that one or more future events will occur confirming the fact of the loss. In the event that an unfavorable outcome is determined to be probable and the amount of the loss can be reasonably estimated, the Company establishes an accrual for the litigation, claim or assessment. In addition, in the event an unfavorable outcome is determined to be less than probable, but reasonably possible, the Company will disclose an estimate of the possible loss or range of such loss; however, when a reasonable estimate cannot be made, the Company will provide disclosure to that effect. Litigation is inherently uncertain and may result in adverse rulings or decisions. Additionally, the Company may enter into settlements or be subject to judgments that may, individually or in the aggregate, have a material adverse effect on its results of operations. Accordingly, actual results could differ materially.

Intellectual Property Litigation

Convolve, Inc. (“Convolve”) and Massachusetts Institute of Technology (“MIT”) v. Seagate Technology LLC, et al.-On July 13, 2000, Convolve and MIT filed suit against Compaq Computer Corporation and Seagate Technology LLC in the U.S. District Court for the Southern District of New York, alleging infringement of U.S. Patent No. 4,916,635 (the “‘635 patent”) and U.S. Patent No. 5,638,267 (the “‘267 patent”), misappropriation of trade secrets, breach of contract, and other claims. On January 16, 2002, Convolve filed an amended complaint, alleging defendants were infringing U.S. Patent No. 6,314,473 (the “‘473 patent”). The district court ruled in 2010 that the ‘267 patent was out of the case.

On August 16, 2011, the district court granted in part and denied in part the Company’s motion for summary judgment. On July 1, 2013, the U.S. Court of Appeals for the Federal Circuit: 1) affirmed the district court’s summary judgment rulings that Seagate did not misappropriate any of the alleged trade secrets and that the asserted claims of the ‘635 patent are invalid; 2) reversed and vacated the district court’s summary judgment of non-infringement with respect to the ‘473 patent; and 3) remanded the case for further proceedings on the ‘473 patent. On July 11, 2014, the district court granted the Company’s further summary judgment motion regarding the ‘473 patent. On February 10, 2016, the U.S. Court of Appeals for the Federal Circuit: 1) affirmed the district court’s summary judgment of no direct infringement by Seagate because Seagate’s ATA/SCSI disk drives do not meet the “user interface” limitation of the asserted claims of the ‘473 patent; 2) affirmed the district court’s summary judgment of non-infringement byCompaq’s products as to claims 1, 3, and 5 of the ‘473 patent because Compaq’s F10 BIOS interface does not meet the “commands” limitation of those claims; 3) vacated the district court’s summary judgment of non-infringement by Compaq’s accused products as to claims 7-15 of the ‘473 patent; 4) reversed the district court’s summary judgment of non-infringement based on intervening rights; and 5) remanded the case to the district court for further proceedings on the ‘473 patent. In view of the rulings made by the district court and the Court of Appeals and the uncertainty regarding the amount of damages, if any, that could be awarded Convolve in this matter, the Company does not believe that it is currently possible to determine a reasonable estimate of the possible range of loss related to this matter.

Enova Technology Corporation v. Seagate Technology (US) Holdings, Inc., et al.-On June 5, 2013, Enova Technology Corporation (“Enova”) filed a complaint against Seagate Technology (US) Holdings, Inc. and Seagate Technology LLC in the U.S. District Court for the District of Delaware alleging infringement of U.S. Patent No. 7,136,995 (the “‘995 patent”), “Cryptographic Device,” and U.S. Patent No. 7,900,057 (the “‘057 patent”), “Cryptographic Serial ATA Apparatus and Method.” The Company believes the claims are without merit and intends to vigorously defend this case. On April 27, 2015, the district court ordered a stay of the case, in view of proceedings regarding the ‘995 and ‘057 patents before the Patent Trial and Appeal Board (“PTAB”) of the U.S. Patent and Trademark Office.  On September 2, 2015, PTAB issued its final written decision that claims 1-15 of the ‘995 patent are held unpatentable. On December 18, 2015, PTAB issued its final written decisions that claims 1-32 and 40-53 of the ‘057 patent are held unpatentable. On February 4, 2016, PTAB issued its final written decision that claims 33-39 of the ‘057 patent are held unpatentable. Enova appealed PTAB’s decisions on the ‘995 patent and the ‘057 patent to the U.S. Court of Appeals for the Federal Circuit. On March 20, 2017, the court of appeals issued its judgment affirming PTAB’s decision on the ‘995 patent. On September 6, 2017, the court of appeals issued its judgment affirming PTAB’s decision on the ‘057 patent. On November 27, 2017, Enova filed a petition for writ of certiorari with the U.S. Supreme Court challenging the court of appeals’ decision on the ‘057 Patent.The Supreme Court denied the petition on April 30, 2018. On May 9, 2018, the district court entered a final judgment of dismissal with prejudice and on the merits on all claims asserted by Enova in its complaint, with each party to bear its own costs and attorneys’ fees. In light of the district court's final judgment of dismissal, the Company does not expect to incur a loss in this matter.

Lambeth Magnetic Structures LLC v. Seagate Technology (US) Holdings, Inc., et al.-On April 29, 2016, Lambeth Magnetic Structures LLC filed a complaint against Seagate Technology (US) Holdings, Inc. and Seagate Technology LLC in the U.S. District Court for the Western District of Pennsylvania, alleging infringement of U.S. Patent No. 7,128,988, “Magnetic Material Structures, Devices and Methods.” The Company believes the claims asserted in the complaint are without merit and intends to vigorously defend this case. The court issued its claim construction ruling on October 18, 2017. No trial date has been set. While the possible range of loss for this matter remains uncertain, the Company estimates the amount of loss to be immaterial to the financial statements.

Environmental Matters

The Company’s operations are subject to U.S. and foreign laws and regulations 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 wastes and the cleanup of contaminated sites. Some of the Company’s operations require environmental permits and controls to prevent and reduce air and water pollution, and these permits are subject to modification, renewal and revocation by issuing authorities.

The Company has established environmental management systems and continually updates its environmental policies and standard operating procedures for its operations worldwide. The Company believes that its operations are in material compliance with applicable environmental laws, regulations and permits. The Company budgets for operating and capital costs on an ongoing basis to comply with environmental laws. If additional or more stringent requirements are imposed on the Company in the future, it could incur additional operating costs and capital expenditures.

Some environmental laws, such as the Comprehensive Environmental Response Compensation and Liability Act of 1980 (as amended, the “Superfund” law) and its state equivalents, can impose liability for the cost of cleanup of contaminated sites upon any of the current or former site owners or operators or upon parties who sent waste to these sites, regardless of whether the owner or operator owned the site at the time of the release of hazardous substances or the lawfulness of the original disposal activity. The Company has been identified as a responsible or potentially responsible party at several sites. At each of these sites, the Company has an assigned portion of the financial liability based on the type and amount of hazardous substances disposed of by each party at the site and the number of financially viable parties. The Company has fulfilled its responsibilities at some of these sites and remains involved in only a few at this time.

While the Company’s ultimate costs in connection with these sites is difficult to predict with complete accuracy, based on its current estimates of cleanup costs and its expected allocation of these costs, the Company does not expect costs in connection with these sites to be material.

The Company may be subject to various state, federal and international laws and regulations governing the environment, including those restricting the presence of certain substances in electronic products. For example, the European Union (“EU”) enacted the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment, which prohibits the use of certain substances, including lead, in certain products, including disk drives and server storage products, put on the market after July 1, 2006. Similar legislation has been or may be enacted in other jurisdictions, including in the United States, Canada, Mexico, Taiwan, China, Japan and others. The European Union REACH Directive (Registration, Evaluation, Authorization, and Restriction of Chemicals, EC 1907/2006) also restricts substances of very high concern (“SVHCs”) in products. If the Company or its suppliers fails to comply with the substance restrictions, recycle requirements or other environmental requirements as they are enacted worldwide, it could have a materially adverse effect on the Company’s business.

Other Matters

The Company is involved in a number of other judicial, regulatory or administrative proceedings and investigations incidental to its business, and the Company may be involved in such proceedings and investigations arising in the normal course of its business in the future. Although occasional adverse decisions or settlements may occur, the Company believes that the final disposition of such matters will not have a material adverse effect on its financial position or results of operations.

Leases. The Company leases certain property, facilities and equipment under non-cancelable lease agreements. Land and facility leases expire at various dates through2082and contain various provisions for rental adjustments including, in certain cases, a provision based on increases in the Consumer Price Index. In addition, certain leases provide for renewal of the lease at the Company's option at expiration of the lease. The lease term begins on the date of initial possession of the leased property for purposes of recognizing lease expense on a straight-line basis over the term of the lease. The Company does not assume renewals in its determination of the lease term unless the renewals are deemed to be reasonably assured at lease inception. All of the leases require the Company to pay property taxes, insurance and normal maintenance costs, which are expensed as incurred.

Future minimum lease payments for operating leases (including accrued lease payments relating to restructuring plans) with initial or remaining terms of one year or more were as follows atJune 29, 2018 (lease payments are shown net of sublease income):

Indemnifications of Officers and Directors

On May 4, 2009, Seagate Technology, an exempted company incorporated with limited liability under the laws of the Cayman Islands (“Seagate-Cayman”), then the parent company, entered into a new form of indemnification agreement (the “Revised Indemnification Agreement”) with its officers and directors of Seagate-Cayman and its subsidiaries (each, an “Indemnitee”). The Revised Indemnification Agreement provides indemnification in addition to any of Indemnitee's indemnification rights under Seagate-Cayman's Articles of Association, applicable law or otherwise, and indemnifies an Indemnitee for certain expenses (including attorneys' fees), judgments, fines and settlement amounts actually and reasonably incurred by him or her in any action or proceeding, including any action by or in the right of Seagate-Cayman or any of its subsidiaries, arising out of his or her service as a director, officer, employee or agent of Seagate-Cayman or any of its subsidiaries or of any other entity to which he or she provides services at Seagate-Cayman's request. However, an Indemnitee shall not be indemnified under the Revised Indemnification Agreement for (i) any fraud or dishonesty in the performance of Indemnitee's duty to Seagate-Cayman or the applicable subsidiary of Seagate-Cayman or (ii) Indemnitee's conscious, intentional or willful failure to act honestly, lawfully and in good faith with a view to the best interests of Seagate-Cayman or the applicable subsidiary of Seagate-Cayman. In addition, the Revised Indemnification Agreement provides that Seagate-Cayman will advance expenses incurred by an Indemnitee in connection with enforcement of the Revised Indemnification Agreement or with the investigation, settlement or appeal of any action or proceeding against him or her as to which he or she could be indemnified.

On July 3, 2010, pursuant to a corporate reorganization, the common shareholders of Seagate-Cayman became ordinary shareholders of Seagate Technology plc (the "Company") and Seagate-Cayman became a wholly owned subsidiary of the Company, as described more fully in the Current Report on Form 8-K filed by the Company on July 6, 2010 (the “Redomestication”). On July 27, 2010, in connection with the Redomestication, the Company, as sole shareholder of Seagate-Cayman, approved a form of deed of indemnity (the “Deed of Indemnity”), which provides for the indemnification by Seagate-Cayman of any director, officer, employee or agent of the Company, Seagate-Cayman or any subsidiary of the Company (each, a “Deed Indemnitee”), in addition to any indemnification rights of a Deed Indemnitee under the Company's Articles of Association, applicable law or otherwise, with a similar scope to the Revised Indemnification Agreement. Seagate-Cayman entered into Deeds of Indemnity with certain Deed Indemnitees effective as of July 3, 2010 and continues to enter into Deeds of Indemnity with additional Deed Indemnitees from time to time.

The nature of these indemnification obligations prevents the Company from making a reasonable estimate of the maximum potential amount it could be required to pay on behalf of its officers and directors. Historically, the Company has not made any significant indemnification payments under such agreements and no amount has been accrued in the Company's consolidated financial statements with respect to these indemnification obligations.

Intellectual Property Indemnification Obligations

The Company has entered into agreements with customers and suppliers that include limited intellectual property indemnification obligations that are customary in the industry. These guarantees generally require the Company to compensate the other party for certain damages and costs incurred as a result of third party intellectual property claims arising from these transactions. The nature of the intellectual property indemnification obligations prevents the Company from making a reasonable estimate of the maximum potential amount it could be required to pay to its customers and suppliers. Historically, the Company has not made any significant indemnification payments under such agreements and no amount has been accrued in the Company's consolidated financial statements with respect to these indemnification obligations.

Product Warranty

The Company estimates probable product warranty costs at the time revenue is recognized. The Company generally warrants its products for a period of 1 to 5 years. The Company uses estimated repair or replacement costs and uses statistical modeling to estimate product return rates in order to determine its warranty obligation. Changes in the Company's product warranty liability during the fiscal years ended June 29, 2018, June 30, 2017 and July 1, 2016 were as follows:

The consolidated financial statements include the accounts of the Company and all its wholly-owned and majority-owned subsidiaries, after elimination of intercompany transactions and balances.

The preparation of financial statements in accordance with U.S. generally accepted accounting principles also requires management to make estimates and assumptions that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. The methods, estimates and judgments the Company uses in applying its most critical accounting policies have a significant impact on the results the Company reports in its consolidated financial statements. Certain prior years amounts reported in the consolidated financial statements and notes thereto have been reclassified to conform to the current year’s presentation.

Fiscal Period

The Company operates and reports financial results on a fiscal year of52 or 53weeks ending on the Friday closest to June 30. Accordingly, fiscal years 2018, 2017 and 2016 were comprised of 52 weeks ended on June 29, 2018, June 30, 2017 and July 1, 2016, respectively. All references to years in these Notes to Consolidated Financial Statements represent fiscal years unless otherwise noted. Fiscal year 2019 will be comprised of 52 weeks and will end on June 28, 2019.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Cash, Cash Equivalents and Short-Term Investments. The Company considers all highly liquid investments with a remaining maturity of 90 days or less at the time of purchase to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value. From time to time, the Company has short-term investments that are primarily comprised of money market funds, time deposits and certificates of deposits. The Company has classified its marketable securities as available-for-sale and they are stated at fair value with unrealized gains and losses included in Accumulated other comprehensive loss, which is a component of Shareholders' Equity. The Company evaluates the available-for sale securities in an unrealized loss position for other-than-temporary impairment. Realized gains and losses are included in Other, net on the Company's Consolidated Statements of Operations. The cost of securities sold is based on the specific identification method.

Restricted Cash and Investments. Restricted cash and investments represent cash and cash equivalents and investments that are restricted as to withdrawal or use for other than current operations.

Allowances for Doubtful Accounts

Allowances for Doubtful Accounts.    The Company maintains an allowance for uncollectible accounts receivable based upon expected collectability. This reserve is established based upon historical trends, global macroeconomic conditions and an analysis of specific exposures. The provision for doubtful accounts is recorded as a charge to Marketing and administrative expense

Inventory

Inventory.  The Company accounts for inventory in accordance with Accounting Standard Codification ("ASC") Topic 330, Inventory. During fiscal year 2018, the Company adopted Accounting Standard Update ("ASU") No. 2015-11, Inventory: Simplifying the Measurement of Inventory (ASC topic 330). Inventories are valued at the lower of cost (using the first-in, first-out method) and net realizable value. Net realizable value is based upon the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.

Property, Equipment and Leasehold Improvements

Property, Equipment and Leasehold Improvements.    Property, equipment and leasehold improvements are stated at cost. Equipment and buildings are depreciated using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated life of the asset or the remaining term of the lease. The costs of additions and substantial improvements to property, equipment and leasehold improvements, which extend the economic life of the underlying assets, are capitalized. The cost of maintenance and repairs to property, equipment and leasehold improvements is expensed as incurred.

Assessment of Goodwill and Other Long-Lived Assets for Impairment

Assessment of Goodwill and Other Long-lived Assets for Impairment. The Company accounts for goodwill in accordance with ASC Topic 350 ("ASC 350"), Intangibles - Goodwill and Other.The Company performs a qualitative assessment in the fourth quarter of each year, or more frequently if indicators of potential impairment exist, to determine if any events or circumstances exist, such as an adverse change in business climate or a decline in the overall industry that would indicate that it would more likely than not reduce the fair value of a reporting unit below its carrying amount, including goodwill. If it is determined in the qualitative assessment that the fair value of a reporting unit is more likely than not below its carrying amount, including goodwill, then the Company will perform a quantitative impairment test. The quantitative goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. Any excess in the carrying value of a reporting unit's goodwill over its fair value is recognized as an impairment loss, limited to the total amount of goodwill allocated to that reporting unit.

The Company tests other long-lived assets, including property, equipment and leasehold improvements and other intangible assets subject to amortization, for recoverability whenever events or changes in circumstances indicate that the carrying value of those assets may not be recoverable. The Company performs a recoverability test to assess the recoverability of an asset group. If the recoverability test indicates that the carrying value of the asset group is not recoverable, the Company will estimate the fair value of the asset group and the excess of the carrying value over the fair value is allocated pro rata to derive the adjusted carrying value of assets in the asset group. The adjusted carrying value of each asset in the asset group is not reduced below its fair value.

The Company tests other intangible assets not subject to amortization whenever events occur or circumstances change, such as declining financial performance, deterioration in the environment in which the entity operates or deteriorating macroeconomic conditions that have a negative effect on future expected earnings and cash flows that could affect significant inputs used to determine the fair value of the indefinite-lived intangible asset.

Investment in Debt Security and Payment-in-Kind (PIK) Income

Investment in Debt Security and Payment-in-Kind (“PIK”) Income. The Company has debt investment in non-convertible preferred stock of K.K. Pangea. The Company determined the appropriate classification of such investment at the time of purchase and will re-evaluate such designation at each balance sheet date. The Company classified the investment as held-to-maturity as it has the positive intent and ability to hold the security until maturity. This held-to-maturity investment is carried at amortized cost and recorded as Investment in debt security on the Consolidated Balance Sheets.

Transaction costs incurred by the Company to acquire this investment are capitalized and amortized as a reduction of interest income on the Consolidated Statements of Operations over the respective term of the investment. The investment contains a PIK income provision, which represents contractual interest that is due at maturity, and is accrued and recorded as Interest income each reporting period and added to the carrying value of the Investment in debt security.

The Company assesses whether an other-than-temporary impairment loss on the debt security, including the accrued PIK income, has occurred due to a decline in fair value or other market conditions. If the fair value of the debt security is below amortized cost and it is more likely than not that the Company will not be able to recover the amortized cost bases before its stated maturity, the Company will record an other-than-temporary impairment charge to Other, net in the Consolidated Statements of Operations.

Derivative Financial Instruments

Derivative Financial Instruments. The Company applies the requirements of ASC Topic 815 ("ASC 815"), Derivatives and Hedging. ASC 815 requires that all derivatives be recorded on the balance sheet at fair value and establishes criteria for designation and effectiveness of hedging relationships. During fiscal year 2018, the Company early adopted ASU No. 2017-12, Derivatives and Hedging (ASC Topic 815) —Targeted Improvements to Accounting for Hedging Activities. The Company continues to exclude the change in forward points from the assessment of hedge effectiveness and recognizes the excluded component in Other, net in the Consolidated Statements of Operations. Foreign currency forward exchange contracts not designated as hedge instruments are used to economically hedge the foreign currency exposure in the value of an investment denominated in currency other than U.S. dollar. The Company recognizes the unrealized gains (losses) due to the changes in the fair value of these contracts in Other, net in the Consolidated Statements of Operations along with the foreign currency gains and losses on remeasurement of such investment.   

The Company is exposed to foreign currency exchange rate, interest rate, and to a lesser extent, equity market risks relating to its ongoing business operations. From time to time, the Company enters into cash flow hedges in the form of foreign currency forward exchange contracts in order to manage the foreign currency exchange rate risk denominated in foreign currencies. The Company’s accounting policies for these instruments are based on whether the instruments are classified as designated or non-designated hedging instruments. The Company records all derivatives in the Consolidated Balance Sheets at fair value. The changes in the fair value of highly effective designated cash flow hedges are recorded in Accumulated other comprehensive loss until the hedged item is recognized in earnings. Derivatives that are not designated as hedging instruments or are not assessed to be highly effective are adjusted to fair value through earnings. The amount of net unrealized gain on cash flow hedges was less than $1 million as of June 29, 2018. The Company had no outstanding cash flow hedges as of June 30, 2017.

The Company de-designates its cash flow hedges when the forecasted hedged transactions affects earnings or it is probable the forecasted hedged transactions will not occur in the initially identified time period. At such time, the associated gains and losses deferred in Accumulated other comprehensive lossare reclassified immediately into earnings and any subsequent changes in the fair value of such derivative instruments are immediately reflected in earnings. The Company did not recognize any material amounts related to the loss of hedge designation on discontinued cash flow hedges during fiscal years 2018, 2017 and 2016.

Other derivatives not designated as hedging instruments consist of foreign currency forward exchange contracts that the Company uses to hedge the foreign currency exposure on the investment in debt security denominated in currency other than the U.S. dollar. The Company recognizes gains and losses on these contracts, as well as the related costs in Other, net on the Consolidated Statement of Operations along with foreign currency gains and losses on investment in debt security.

Establishment of Warranty Accruals

Establishment of Warranty Accruals.    The Company estimates probable product warranty costs at the time revenue is recognized. The Company generally warrants its products for a period of1 to 5years. The Company's warranty provision considers estimated product failure rates and trends (including the timing of product returns during the warranty periods), and estimated repair or replacement costs related to product quality issues, if any. The Company also exercises judgment in estimating its ability to sell certain repaired products. Should actual experience in any future period differ significantly from its estimates, the Company's future results of operations could be materially affected.

Product Warranty

The Company estimates probable product warranty costs at the time revenue is recognized. The Company generally warrants its products for a period of 1 to 5 years. The Company uses estimated repair or replacement costs and uses statistical modeling to estimate product return rates in order to determine its warranty obligation.

Revenue Recognition, Sales Returns and Allowances, and Sales Incentive Programs

Revenue Recognition, Sales Returns and Allowances, and Sales Incentive Programs.    The Company's revenue recognition policy complies with ASC Topic 605 ("ASC 605"), Revenue Recognition. Revenue from sales of products, including sales to distribution customers, is generally recognized when title and risk of loss has passed to the buyer, which typically occurs upon shipment from the Company or third party's warehouse facilities, persuasive evidence of an arrangement exists, including a fixed or determinable price to the buyer, and when collectability is reasonably assured. Revenue from sales of products to certain direct retail customers and to customers in certain indirect retail channels is recognized on a sell-through basis.

The Company records estimated product returns at the time of shipment. The Company also estimates reductions to revenue for sales incentive programs, such as price protection, and volume incentives, and records such reductions when revenue is recorded. The Company establishes certain distributor and OEM sales programs aimed at increasing customer demand. For OEM sales, rebates are typically based on an OEM customer's volume of purchases from Seagate or other agreed upon rebate programs. For the distribution channel, these programs typically involve rebates related to a distributor's level of sales, order size, advertising or point of sale activity and price protection adjustments. The Company provides for these obligations at the time that revenue is recorded based on estimated requirements. Marketing development programs are recorded as a reduction to revenue.

Shipping and Handling

Shipping and Handling.    The Company includes costs related to shipping and handling in Cost of revenue in the Consolidated Statements of Operations for all periods presented.

Restructuring Costs

Restructuring Costs.     The Company records restructuring activities including costs for one-time termination benefits in accordance with ASC Topic 420 ("ASC 420"), Exit or Disposal Cost Obligations. The timing of recognition for severance costs accounted for under ASC 420 depends on whether employees are required to render service until they are terminated in order to receive the termination benefits. If employees are required to render service until they are terminated in order to receive the termination benefits, a liability is recognized ratably over the future service period. Otherwise, a liability is recognized when management has committed to a restructuring plan and has communicated those actions to employees. Employee termination benefits covered by existing benefit arrangements are recorded in accordance with ASC Topic 712, Nonretirement Postemployment Benefits. These costs are recognized when management has committed to a restructuring plan and the severance costs are probable and estimable.

Advertising Expense

Advertising Expense.    The cost of advertising is expensed as incurred. Advertising costs were approximately $28 million, $16 million and $31 million in fiscal years 2018, 2017 and 2016, respectively.

Stock-Based Compensation

Share-Based Compensation.    The Company accounts for share-based compensation under the provisions of ASC Topic 718 (ASC 718), Compensation-Stock Compensation. During fiscal year 2018, the Company adopted ASU 2016-09, Stock Compensation—Improvements to Employee Share-Based Payment Accounting (ASC Topic 718). The Company has elected to apply the with-and-without method to assess the realization of related excess tax benefits. The Company also elected to continue to account for share-based compensation expense net of estimated forfeitures.

Determining Fair Value of Seagate Technology Stock Plans

Valuation and amortization method - The Company estimates the fair value of stock options, RSU and performance awards subject to an AEPS condition granted using the Black-Scholes-Merton valuation model and a single share award approach. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period or the remaining service (vesting) period.

Expected Term - Expected term represents the period that the Company's share-based awards are expected to be outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual terms of the share-based awards, vesting schedules and expectations of future employee behavior as influenced by changes to the terms of its share-based awards.

Expected Volatility - The Company uses a combination of the implied volatility of its traded options and historical volatility of its share price.

Expected Dividend - The Black-Scholes-Merton valuation model calls for a single expected dividend yield as an input. The dividend yield is determined by dividing the expected per share dividend during the coming year by the grant date share price. The expected dividend assumption is based on the Company's current expectations about its anticipated dividend policy. Also, because the expected dividend yield should reflect marketplace participants' expectations, the Company does not incorporate changes in dividends anticipated by management unless those changes have been communicated to or otherwise are anticipated by marketplace participants.

Risk-Free Interest Rate - The Company bases the risk-free interest rate used in the Black-Scholes-Merton valuation model on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term. Where the expected term of the Company's share-based awards do not correspond with the terms for which interest rates are quoted, the Company performed a straight-line interpolation to determine the rate from the available term maturities.

Accounting for Income Taxes

Accounting for Income Taxes. The Company accounts for income taxes pursuant to ASC Topic 740 ("ASC 740"), Income Taxes. During fiscal year 2018, the Company adopted ASU 2016-16, Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory (ASC Topic 740). In applying ASC 740, the Company makes certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of tax credits, recognition of income and deductions and calculation of specific tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for income tax and financial statement purposes, as well as tax liabilities associated with uncertain tax positions. The calculation of tax liabilities involves uncertainties in the application of complex tax rules and the potential for future adjustment of the Company’s uncertain tax positions by the Internal Revenue Service or other tax jurisdictions. If estimates of these tax liabilities are greater or less than actual results, an additional tax benefit or provision will result. The deferred tax assets the Company records each period depend primarily on the Company’s ability to generate future taxable income in the United States and certain non-U.S. jurisdictions. Each period, the Company evaluates the need for a valuation allowance for its deferred tax assets and, if necessary, adjusts the valuation allowance so that net deferred tax assets are recorded only to the extent the Company concludes it is more likely than not that these deferred tax assets will be realized. If the Company’s outlook for future taxable income changes significantly, the Company’s assessment of the need for, and the amount of a valuation allowance may also change.

Comprehensive Income

Comprehensive Income. The Company presents comprehensive income in a separate statement. Comprehensive income is comprised of net income and other gains and losses affecting equity that are excluded from net income.

Foreign Currency Remeasurement and Translation

Foreign Currency Remeasurement and Translation.    The U.S. dollar is the functional currency for the majority of the Company's foreign operations. Monetary assets and liabilities denominated in foreign currencies are remeasured into the functional currency of the subsidiary at the balance sheet date. The gains and losses from the remeasurement of foreign currency denominated balances into the functional currency of the subsidiary are included in Other, net on the Company's Consolidated Statements of Operations. The Company’s subsidiaries that use the U.S. dollar as their functional currency remeasure monetary assets and liabilities at exchange rates in effect at the end of each period, and nonmonetary assets and liabilities at historical rates.

The Company had $3 million, $9 million and $3 million in remeasurement losses in fiscal years 2018, 2017 and 2016, respectively.

The Company translates the assets and liabilities of its non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period. Revenue and expenses for these subsidiaries are translated using rates that approximate those in effect during the period. Gains and losses from these translations are recognized in foreign currency translation included in Accumulated other comprehensive loss, which is a component of shareholders’ equity.

Concentration of Credit Risk

Concentrations

Concentration of Credit Risk.    The Company's customer base for disk drive products is concentrated with a small number of customers. The Company does not generally require collateral or other security to support accounts receivable. To reduce credit risk, the Company performs ongoing credit evaluations on its customers' financial condition. The Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of customers, historical trends and other information. Dell Inc. accounted for more than 10% of the Company's accounts receivable as of June 29, 2018 and June 30, 2017.

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents, investments and foreign currency forward exchange contracts. The Company mitigates concentrations of credit risk in its investments through diversifications, by investing in highly-rated securities or major multinational companies.

In entering into foreign currency forward exchange contracts, the Company assumes the risk that might arise from the possible inability of counterparties to meet the terms of their contracts. The counterparties to these contracts are major multinational commercial banks, and the Company has not incurred and does not expect any losses as a result of counterparty defaults.

Supplier Concentration.Certain of the raw materials, components and equipment used by the Company in the manufacture of its products are available from single-sourced vendors. Shortages could occur in these essential materials and components due to an interruption of supply or increased demand in the industry. If the Company were unable to procure certain materials, components or equipment at acceptable prices, it would be required to reduce its manufacturing operations, which could have a material adverse effect on its results of operations. In addition, the Company may make prepayments to certain suppliers or enter into minimum volume commitment agreements. Should these suppliers be unable to deliver on their obligations or experience financial difficulty, the Company may not be able to recover these prepayments.

Recent Accounting Pronouncements

Recently Issued Accounting Pronouncements

In May 2014, August 2015, April 2016, May 2016 and December 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09 (ASC Topic 606), Revenue from Contracts with Customers, ASU 2015-14 (ASC Topic 606) Revenue from Contracts with Customers, Deferral of the Effective Date, ASU 2016-10 (ASC Topic 606) Revenue from Contracts with Customers, Identifying Performance Obligations and Licensing, ASU 2016-12 (ASC Topic 606) Revenue from Contracts with Customers, Narrow-Scope Improvements and Practical Expedients, and ASU 2016-20 (ASC Topic 606) Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, respectively. ASC Topic 606 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. It also requires entities to disclose both quantitative and qualitative information that enable financial statements users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company is required to adopt the guidance in the first quarter of fiscal year 2019. This standard may be applied retrospectively to all prior periods presented, or retrospectively with a cumulative adjustment to retained earnings in the year of adoption (“modified retrospective transition approach”). The Company will adopt this standard in the first quarter of fiscal year 2019 utilizing the modified retrospective transition approach.

The Company has substantially completed its evaluation and expects the adoption of the new standard will result in the recognition of revenue when the products are delivered (sell-in basis) to certain direct retail customers and customers in certain indirect retail channels which are currently being recognized on a sell-through basis. Accordingly, the Company will estimate appropriate accruals for the variable consideration (e.g. rebates) related to customer incentives on these arrangements. On the date of initial adoption, the Company will remove the deferred income that would have been subsequently recognized on a sell-through basis and record estimates of the accruals for variable consideration through a cumulative adjustment to accumulated deficit. The Company believes that these changes will not have a material impact on the Company’s consolidated financial statements and internal controls over financial reporting.

In January 2016, the FASB issued ASU 2016-01 (ASC Subtopic 825-10), Financial Instruments—Overall Recognition and Measurement of Financial Assets and Financial Liabilities, as amended by ASU 2018-03, Financial Instruments—Overall: Technical Correction and Improvements, issued in February 2018. The amendments in these ASUs require entities to measure all investments in equity securities at fair value with changes recognized through net income. This requirement does not apply to investments that qualify for the equity method of accounting, to those that result in consolidation of the investee, or for which the entity meets a practicability exception to fair value measurement. Additionally, the amendments eliminate certain disclosure requirements related to financial instruments measured at amortized cost and add disclosures related to the measurement categories of financial assets and financial liabilities. The Company is required to adopt the guidance in the first quarter of fiscal year 2019. Early adoption is permitted for only certain portions of the ASU. The Company expects to elect the measurement alternative for measurement of equity investments, defined as cost, less impairments, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment in the same issuer (the “Price Changes”) until the equity investments’ fair value becomes readily determinable. The amount of the impact to equity investments will depend on any Price Changes observed after adoption in the first quarter of fiscal year 2019.

In February 2016 and July 2018, the FASB issued ASU 2016-02 (ASC Topic 842), Leases, ASU 2018-10, Codification Improvements to Topic 842, Leases, ASU 2018-11, Leases (ASC Topic 842), Targeted Improvements, respectively. ASC Topic 842 amends a number of aspects of lease accounting, including requiring lessees to recognize operating leases with a term greater than one year on their balance sheet as a right-of-use asset and corresponding lease liability, measured at the present value of the lease payments. The Company is required to adopt this guidance in the first quarter of fiscal year 2020. Early adoption is permitted. The Company is in the process of assessing the impact of these ASUs on its consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13 (ASC Topic 326), Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments. This ASU amends the requirement on the measurement and recognition of expected credit losses for financial assets held. The Company is required to adopt this guidance in the first quarter of fiscal year 2021. Early adoption in the first quarter of fiscal year 2020 is permitted. The Company is in the process of assessing the impact of this ASU on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01 (ASC Topic 805), Business Combinations: Clarifying the Definition of a Business. The amendments in this ASU change the definition of a business to assist with evaluating when a set of transferred assets and activities is a business. The Company plans to adopt the guidance in the first quarter of fiscal year 2019. The Company does not expect the adoption of this ASU will have a material impact on its consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09 (ASC Topic 718), Stock Compensation: Scope of Modification Accounting. The amendments in this ASU provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The Company plans to adopt the guidance in the first quarter of fiscal year 2019. The Company does not expect the adoption of this ASU will have a material impact on its consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02 (ASC Topic 220), Income Statement—Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU was issued following the enactment of the U.S. Tax Cuts and Jobs Act of 2017 (the “Tax Act”) and permits entities to elect a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. The Company is required to adopt the guidance in the first quarter of fiscal year 2020. Early adoption is permitted. The Company is in the process of assessing the impact of this ASU on its consolidated financial statements.

Recently Adopted Accounting Pronouncements

In July 2015, the FASB issued ASU 2015-11 (ASC Topic 330), Inventory: Simplifying the Measurement of Inventory. The amendments in this ASU require inventory measurement at the lower of cost and net realizable value. This ASU became effective and was adopted by the Company in the September 2017 quarter on a prospective basis. The adoption of this guidance had no material impact on the Company’s consolidated financial statements and disclosures.

In March 2016, the FASB issued ASU 2016-09 (ASC Topic 718), Stock Compensation—Improvements to Employee Share-Based Payment Accounting. The amendments in this ASU are intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax consequences, classification on the consolidated statement of cash flows and treatment of forfeitures. This ASU became effective and was prospectively adopted by the Company in the September 2017 quarter. Upon adoption, excess tax benefits or deficiencies from share-based award activity are reflected in the Consolidated Statements of Operations as a component of the provision for income taxes, whereas they previously were recognized in the Shareholders’ equity in the Consolidated Balance Sheets. The Company also elected to continue to account for share-based compensation expense net of estimated forfeitures. The adoption of this ASU resulted in an increase in deferred tax assets relating to net operating losses of approximately$0.6 billion, offset by an equivalent increase in the valuation allowance with no impact to retained earnings. The adoption of this guidance had no material impact on the Company’s consolidated financial statements and disclosures.

In October 2016, the FASB issued ASU 2016-16 (ASC Topic 740), Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory. The amendments in this ASU require the recognition of the income tax consequences for intra-entity transfers of assets other than inventory when the transfer occurs. The Company elected to early adopt this ASU in the September 2017 quarter on a modified retrospective basis with no material impact on the Company’s consolidated financial statements and disclosures.

In August 2017, the FASB issued ASU 2017-12 (ASC Topic 815), Derivatives and Hedging, Targeted Improvements to Accounting for Hedging Activities. The amendments in this ASU simplify the application of hedge accounting guidance and more closely aligning financial reporting for hedging relationships with economic results of an entity's risk management activities. The Company early adopted this ASU in the June 2018 quarter. The adoption of this guidance had no material impact on the Company's consolidated financial statements and disclosures.

Fair Value, Policy

Measurement of Fair Value

Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

Fair Value Hierarchy

A fair value hierarchy is based on whether the market participant assumptions used in determining fair value are obtained from independent sources (observable inputs) or reflects the Company's own assumptions of market participant valuation (unobservable inputs). A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of inputs that may be used to measure fair value are:

Level 1 - Quoted prices in active markets that are unadjusted and accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 - Quoted prices for identical assets and liabilities in markets that are inactive; quoted prices for similar assets and liabilities in active markets or financial instruments for which significant inputs are observable, either directly or indirectly; or

Level 3 - Prices or valuations that require inputs that are both unobservable and significant to the fair value measurement.

The Company considers an active market to be one in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis, and views an inactive market as one in which there are few transactions for the asset or liability, the prices are not current, or price quotations vary substantially either over time or among market makers. Where appropriate, the Company's or the counterparty's non-performance risk is considered in determining the fair values of liabilities and assets, respectively.

Leases

Leases. The Company leases certain property, facilities and equipment under non-cancelable lease agreements. Land and facility leases expire at various dates through2082and contain various provisions for rental adjustments including, in certain cases, a provision based on increases in the Consumer Price Index. In addition, certain leases provide for renewal of the lease at the Company's option at expiration of the lease. The lease term begins on the date of initial possession of the leased property for purposes of recognizing lease expense on a straight-line basis over the term of the lease. The Company does not assume renewals in its determination of the lease term unless the renewals are deemed to be reasonably assured at lease inception. All of the leases require the Company to pay property taxes, insurance and normal maintenance costs, which are expensed as incurred.

Earnings Per Share [Abstract]

Schedule of computation of basic and diluted net income (loss) per share

Basic earnings per share is computed by dividing income available to shareholders by the weighted-average number of shares outstanding during the period. Diluted earnings per share is computed by dividing income available to shareholders by the weighted-average number of shares outstanding during the period and the number of additional shares that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding options, unvested restricted stock units and performance-based share units and shares to be purchased under the Employee Stock Purchase Plan ("ESPP"). The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method. Under the treasury stock method, an increase in fair market value of the Company’s share price can result in a greater dilutive effect from potentially dilutive securities. The following table sets forth the computation of basic and diluted net income per share attributable to the shareholders of the Company:
