OEMs    Direct sales to OEMs accounted for approximately 34% of our revenues in 2017, 38% of our revenues in 2016 and 39% of our revenues in 2015. OEM customers include a variety of companies in the electronics industry such as Bosch GmbH, Continental Automotive Systems, Delphi, Hella, Huawei Technologies Co. Ltd., Magna International, Panasonic Corporation and Samsung Electronics Co., Ltd. (“Samsung”). We focus on three types of OEMs: multi-nationals; selected regional accounts; and target market customers. Large multi-nationals and selected regional accounts, which are significant in specific markets, are our core OEM customers. The target market customers for ourend-markets are OEMs that are on the leading edge of specific technologies and provide direction for technology and new product development. Generally, our OEM customers do not have the right to return our products following a sale other than pursuant to our standard warranty.

Distributors    Sales to distributors accounted for approximately 60% of our revenues in 2017, 56% of our revenues in 2016 and 54% of our revenues in 2015, the year-over-year increase being attributed to our acquisition of Fairchild, which had a greater distribution mix than our historical business. Our distributors, which includeArrow, Avnet, Macnica, OS Electronics, World Peace and WT Microelectronics, resell tomid-sized and smaller OEMs and to electronic manufacturing service providers and other companies. Sales to certain distributors are made pursuant to agreements that provide return rights with respect to discontinued or slow-moving products. Under certain agreements, distributors are allowed to return any product that we have removed from our price book. In addition, agreements with certain of our distributors contain stock rotation provisions permitting limited levels of product returns. We developed our new internal processes and systems, which have enabled us to reliably estimate upfront the effects of returns and allowances and thus began recognizing revenue at the time of sales to the distributors beginning in the first quarter of 2017. Prior to 2017, for products sold to distributors who are entitled to returns and allowances (generally referred to as “ship and credit rights”), we recognized related revenues and cost of revenues when we were informed by the distributors that they had resold the products to theend-user.

Electronic Manufacturing Service Providers    Direct sales to electronic manufacturing service providers accounted for approximately 6% of our revenues in 2017, 6% of our revenues in 2016 and 7% of our revenues in 2015.Among our largestelectronic manufacturing service customers are Benchmark Electronic, Flextronics, Jabil and Sanmina. These customers are manufacturers who typically provide contract manufacturing services for OEMs. Originally, these companies were involved primarily in the assembly of printed circuit boards, but they now typically provide design, supply management and manufacturing solutions as well. Many OEMs now outsource a large part of their manufacturing to electronic manufacturing service providers in order to focus on their core competencies. We are pursuing a number of strategies to penetrate this increasingly important marketplace. Generally, our electronic manufacturing service customers do not have the right to return our products following a sale other than pursuant to our standard warranty.

See “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Note 18: “Segment Information” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K for revenues by geographic locations.

We operate all of our manufacturing facilities directly, with the exception of our assembly and test operations facility located in Leshan, China, which is owned by Leshan. Our investment in Leshan has been consolidated in our financial statements. Our joint venture partner, Leshan Radio Company Ltd., is formerly a state-owned enterprise. Pursuant to the joint venture agreement, requests for production capacity are made to the board of directors of Leshan by each shareholder of the joint venture. Each request represents a purchase commitment by the requesting shareholder, provided that the shareholder may elect to pay the cost associated with the unused capacity (which is generally equal to the fixed cost of the capacity) in lieu of satisfying the commitment. We committed to purchase 80% of Leshan’s production capacity in each of 2017, 2016 and 2015 and are currently committed to purchase approximately 80% of Leshan’s expected production capacity in 2018.

We use third-party contractors for some of our manufacturing activities, primarily for wafer fabrication and the assembly and testing of finished goods. Our agreements with these contract manufacturers typically require us to

13

forecast product needs and commit to purchase services consistent with these forecasts. In some cases,longer-term commitments are required in the early stages of the relationship. These contract manufacturers, including Amkor, ASE, Kingpak, SMIC, TPSCo and TSMC, collectively accounted for approximately 36%, 36% and 39% of our manufacturing costs in 2017, 2016 and 2015, respectively.

For information regarding risks associated with our foreign operations, see “Risk Factors - Trends, Risks and Uncertainties Related to Our Business” included elsewhere in this Form10-K.

Raw Materials

Our manufacturing processes use many raw materials, including silicon wafers, gold, copper, lead frames, mold compound, ceramic packages and various chemicals and gases as well as other production supplies used in our manufacturing processes. We obtain our raw materials and supplies from a large number of sources, generally on ajust-in-time basis, and material agreements with our suppliers that impose minimum or continuing supply obligations are reflected in our contractual obligations table in “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources - Contractual Obligations” included elsewhere in this Form10-K. From time to time, suppliers may extend lead times, limit supplies or increase prices due to capacity constraints or other factors. Although we believe that supplies of the raw materials we use are currently and will continue to be available, shortages could occur in various essential materials due to interruption of supply, increased demand in the industry or other factors.

Sales, Marketing and Distribution

As of December 31, 2017, our sales and marketing organization consisted of approximately 1,700 professionals servicing customers globally. We support our customers through logistics organizations andjust-in-time warehouses. Global and regional distribution channels further support our customers’ needs for quick response and service. We offer efficient, cost-effective global applications support from our Technical Information Centers and Solution Engineering Centers, allowing for applications which are developed in one region of the world to be instantaneously available throughout all other regions.

Patents, Trademarks, Copyrights and Other Intellectual Property Rights

We market our products primarily under our registered trademark ON Semiconductor^® and our ON logo, and, in the United States and internationally, we rely primarily on a combination of patents, trademarks, copyrights, trade secrets, employee andnon-disclosure agreements and licensing agreements to protect our intellectual property. We acquired or were licensed or sublicensed to a significant amount of IP, including patents and patent applications, in connection with our acquisitions, and we have numerous U.S. and foreign patents issued, allowed and pending. As of December 31, 2017, we held patents with expiration dates ranging from 2018 to 2038, and none of the patents that expire in the next three years materially affect our business. Our policy is to protect our products and processes by asserting our IP rights where appropriate and prudent and by obtaining patents, copyrights and other IP rights used in connection with our business when practicable and appropriate.

Seasonality

We believe our business today is driven more by secular growth drivers and not solely by macroeconomic and industry cyclicality, as was the case historically. However, in the future, we could again experienceperiod-to-period fluctuations in operating results due to general industry or economic conditions. For information regarding risks associated with the cyclicality and seasonality of our business, see “Risk Factors - Trends, Risks and Uncertainties Related to Our Business” included elsewhere in this Form10-K.

14

Backlog and Inventory

Our trade sales are made primarily pursuant to orders that are predominantly booked as far as 26 weeks in advance of delivery. Generally, prices and quantities are fixed at the time of booking. Backlog as of a given date consists of existing orders and forecasted demand from our Electronic Data Interface customers, in each case scheduled to be shipped over the13-week period following such date. Backlog is influenced by several factors, including market demand, pricing and customer order patterns in reaction to product lead times. During 2017, our backlog at the beginning of each quarter represented between 83% and 89% of actual revenues during such quarter, which is consistent with backlog levels in recent prior periods. As manufacturing capacity utilization in the industry increases, customers tend to order products further in advance and, as a result, backlog at the beginning of a period as a percentage of revenues during such period is likely to increase.

In the semiconductor industry, backlog quantities and shipment schedules under outstanding purchase orders are frequently revised to reflect changes in customer needs. Agreements calling for the sale of specific quantities are either contractually subject to quantity revisions or, as a matter of industry practice, are often not enforced. Therefore, a significant portion of our order backlog may be cancelable. For these reasons, the amount of backlog as of any particular date may not be an accurate indicator of future results.

We sell products to key customers pursuant to contracts that allow us to schedule production capacity in advance and allow the customers to manage their inventory levels consistent withjust-in-time principles while shortening the cycle times required for producing ordered products. However, these contracts are typically amended to reflect changes in customer demands and periodic price renegotiations. We routinely generate inventory based on customers’ estimates ofend-user demand for their products, which is difficult to predict. See “Risk Factors - Trends, Risks and Uncertainties Related to Our Business” located elsewhere in this Form10-K for additional information regarding the inventory practices within the semiconductor industry.

Competition

The semiconductor industry, particularly the market for general-purpose semiconductor products like ours, is highly competitive. We face significant competition within each of our product lines from major international semiconductor companies, as well as smaller companies focused on specific market niches. Because some of our components are often building block semiconductors that, in some cases, can be integrated into more complex ICs, we also face competition from manufacturers of ICs, ASICs and fully-customized ICs, as well as customers who develop their own IC products. See “Risk Factors - Trends, Risks and Uncertainties Related to Our Business” included elsewhere in this Form10-K for additional information.

In comparison, several competitors noted below are larger in scale and size, have substantially greater financial and other resources with which to pursue development, engineering, manufacturing, marketing and distribution of their products and may generally be better situated to withstand adverse economic or market conditions. The semiconductor industry has experienced, and may continue to experience, significant consolidation among companies and vertical integration among customers. The following discusses the effects of competition on our three operating segments:

Power Solutions Group

The Power Solutions Group is a leading provider of power semiconductors to the automotive, industrial, wireless and mass markets. Our competitive strengths include our core competencies of leading edge fabrication

15

technologies, micro packaging expertise, breadth of product line and IP portfolio, high quality cost effective manufacturing and supply chain management which ensures supply to our customers. Our commitment to continual innovation allows us to provide an ever broader range of semiconductor solutions to our customers who differentiate in power density and power efficiency, the key performance characteristics driving our markets.

The principal methods of competition in our discrete, module and integrated semiconductor products are through new products and package innovations enabling enhanced performance over existing products. Of particular importance are our power MOSFETs, IGBTs, rectifiers and power module portfolio for power conversion applications and ESD portfolio forhi-speed serial interface protection products where we believe we have significant performance advantages over our competition. Certain of the Power Solutions Group’s competitors include: Broadcom Limited, Diodes Incorporated, Infineon Technologies AG, KEC Corporation, NXP Semiconductors N.V., Rohm Semiconductor, Semtech Corporation, STMicroelectronics N.V., Texas Instruments Inc., Toshiba Corporation and Vishay Intertechnology, Inc.

Analog Solutions Group

The principal bases for competition in the Analog Solutions Group are design experience, manufacturing capability, depth and quality of IP, ability to service customer needs from the design phase to the shipping of a completed product, length of design cycle, longevity of technology support and experience of sales and technical support personnel. Our competitive position is also enhanced by long-standing relationships with leading OEM customers.

Our ability to compete successfully depends on internal and external variables, both inside and outside of our control. These variables include, but are not limited to, the timeliness with which we can develop new products and technologies, product performance and quality, manufacturing yields and availability of supply, customer service, pricing, industry trends and general economic trends. Competitors for certain of the Analog Solutions Group’s products and solutions include: Infineon Technologies AG, Maxim Integrated Products, Inc., NXP Semiconductors N.V., Renesas Electronics Corporation, STMicroelectronics N.V. and Texas Instruments Inc.

Image Sensor Group

The Image Sensor Group differentiates itself from the competition by leveraging deep technical knowledge and close customer relationships to drive the most compelling imaging experience for end users. The Image Sensor Group has over four decades of CCD imaging experience and was the first to commercialize CMOS active pixel sensors. The Image Sensor Group was also the first to introduce CMOS technology into many of our markets, leveraging this expertise into market leading positions in automotive and industrial applications, bringing a wealth of technical andend-user applications knowledge to help customers develop innovative imaging solutions across a broad range ofend-user needs. Competitors for certain of the Image Sensor Group’s products and solutions include: Sony Semiconductor, Samsung, Omnivision, STMicroelectronics N.V. and Toshiba Corporation for image sensors, and Rohm Semiconductor, Renesas Electronics Corporation and Dongwoon Anatech for actuator drivers.

Research and Development

Research and development costs in 2017, 2016 and 2015 were $594.4 million, $452.3 million and $396.7 million, representing 11%, 12% and 11% of revenue, respectively. We seek to maximize the investment of our people and capital in research and development by targeting innovative products and solutions for high

16

growth applications that position the Company to outperform the industry. Our design expertise in analog, digital, mixed signal and imaging ICs, combined with our extensive portfolio of standard products, enable the company to offer comprehensive, value added solutions to our global customers for their electronics systems.

Government Regulation

Our manufacturing operations are subject to environmental and worker health and safety laws and regulations. These laws and regulations include those relating to emissions and discharges into the air and water, the management and disposal of hazardous substances, the release of hazardous substances into the environment at or from our facilities and at other sites and the investigation and remediation of contamination. As with other companies engaged in like businesses, the nature of our operations exposes us to the risk of liabilities and claims, regardless of fault, with respect to such matters, including personal injury claims and civil and criminal fines.

Our headquarters in Phoenix, Arizona are located on property that is a “Superfund” site, which is a property listed on the National Priorities List and subject toclean-up activities under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”). Motorola and Freescale have been involved in the cleanup ofon-site solvent-contaminated soil and groundwater andoff-site contaminated groundwater pursuant to consent decrees with the State of Arizona. As part of our separation from Motorola in 1999, Motorola retained responsibility for this contamination, and Motorola and Freescale have agreed to indemnify us with respect to remediation costs and other costs or liabilities related to this matter.

Our formerfront-end manufacturing location in Aizu, Japan is located on property where soil and ground water contamination was detected. We believe that the contamination originally occurred during a time when the facility was operated by a prior owner. We worked with local authorities to implement a remediation plan and have completed remediation construction. The majority of the cost of remediation was covered by insurance. Semi-annual groundwater monitoring has continued to indicate that the treatment was effective. Any costs to us in connection with this matter have not been, and, based on the information available, are not expected to be, material.

Our manufacturing facility in the Czech Republic has ongoing remediation projects to respond to releases of hazardous substances that occurred during the years that this facility was operated by government-owned entities. The remediation projects consist primarily of monitoring groundwater wells locatedon-site andoff-site, with additional action plans developed to respond in the event activity levels are exceeded. The government of the Czech Republic has agreed to indemnify us and our respective subsidiaries, subject to specified limitations, for remediation costs associated with this historical contamination. Based upon the information available, we do not believe that total future remediation costs to us will be material.

Our design center in East Greenwich, Rhode Island is located on property that has localized soil contamination. When we purchased the East Greenwich facility, we entered into a Settlement Agreement and Covenant Not To Sue with the State of Rhode Island. This agreement requires that remedial actions be undertaken and a quarterly groundwater monitoring program be initiated by the former owners of the property. Any costs to us in connection with this matter have not been, and, based on the information available, are not expected to be, material.

As a result of the acquisition of AMIS in 2008, we are a “primary responsible party” to an environmental remediation and cleanup at AMIS’s former corporate headquarters in Santa Clara, California. Costs incurred by AMIS include implementation of theclean-up plan, operations and maintenance of remediation systems and other project management costs. However, AMIS’s former parent company, a subsidiary of Nippon Mining,

17

contractually agreed to indemnify AMIS and us for any obligations relating to environmental remediation andclean-up at this location. Any costs to us in connection with this matter have not been, and, based on the information available, are not expected to be, material.

Through the acquisition of Fairchild, we acquired a facility in South Portland, Maine. The facility has ongoing environmental remediation projects to respond to certain releases of hazardous substances that occurred prior to the leveraged recapitalization of Fairchild from its former parent company, National Semiconductor Corporation, which is now owned by Texas Instruments, Inc. Although we may incur certain liabilities with respect to the above remediation projects, pursuant to the asset purchase agreement entered into in connection with the Fairchild recapitalization, National Semiconductor Corporation agreed to indemnify Fairchild, without limitation and for an indefinite period of time, for all future costs related to these projects. Under a 1999 asset purchase agreement pursuant to which Fairchild purchased the power device business of Samsung, Samsung agreed to indemnify Fairchild in an amount up to $150.0 million for remediation costs and other liabilities related to historical contamination at Samsung’s Bucheon, South Korea operations. The costs incurred to respond to the above conditions and projects have not been, and are not expected to be, material, and any future payments we make in connection with such liabilities are not expected to be material.

Under a 2001 asset purchase agreement pursuant to which Fairchild purchased a manufacturing facility in Mountain Top, Pennsylvania, Intersil Corp. agreed to indemnify Fairchild for remediation costs and other liabilities related to historical contamination at the facility. The costs incurred to respond to these conditions have not been, and are not expected to be, material, and any future payments we make in connection with such liabilities are not expected to be material.

We were notified by the United States Environmental Protection Agency (the “EPA”) that we have been identified as a “potentially responsible party” (“PRP”) under CERCLA in the Chemetco Superfund matter. Chemetco, a defunct reclamation services supplier that operated in Illinois at what is now a Superfund site, has performed reclamation services for us in the past. The EPA is pursuing Chemetco customers for contribution to the site cleanup activities. We have joined a PRP group which is cooperating with the EPA in the evaluation and funding of the cleanup. Based on the information available, any costs to us in connection with this matter have not been, and are not expected to be, material.

We believe that our operations are in material compliance with applicable environmental and health and safety laws and regulations. The costs we incurred in complying with applicable environmental regulations for fiscal year ended December 31, 2017 were not material, and we do not expect the cost of complying with existing environmental and health and safety laws and regulations, together with any liabilities for currently known environmental conditions, to have a material adverse effect on the capital expenditures, earnings or competitive position of the Company or its subsidiaries. It is possible, however, that future developments, including changes in laws and regulations, government policies, customer specification, personnel and physical property conditions, including currently undiscovered contamination, could lead to material costs, and such costs may have a material adverse effect on our future business or prospects. See Note 12: “Commitments and Contingencies” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K for information on certain environmental matters.

Employees

As of December 31, 2017, we had approximately 34,000 employees worldwide, of which approximately 4,500 employees were in the United States. None of our employees in the United States are covered by collective bargaining agreements, except for approximately 90 of our employees (or approximately 2% of our U.S. based

18

employees) at the Mountain Top, Pennsylvania manufacturing facility. Certain of our foreign employees are covered by collective bargaining arrangements (e.g., those in China, Korea, Japan and Belgium) or similar arrangements or are represented by workers councils. For information regarding employee risk associated with our international operations, see “Risk Factors - Trends, Risks and Uncertainties Related to Our Business” included elsewhere in this Form10-K. Of the total number of our employees as of December 31, 2017, approximately 28,100 were engaged in manufacturing, approximately 3,100 were engaged in research and development, approximately 1,700 were engaged in our sales and marketing organization, which includes customer service and approximately 1,100 were engaged in administration.

dispositions; risks that acquisitions or dispositions disrupt our current plans and operations, the risk of unexpected costs, charges or expenses resulting from acquisitions or dispositions and difficulties encountered from integrating and consolidating and timely filing financial information with the SEC for acquired businesses and accurately predicting the future financial performance of acquired businesses); competitor actions, including the adverse impact of competitor product announcements; pricing and gross profit pressures; loss of key customers; order cancellations or reduced bookings; changes in manufacturing yields; control of costs and expenses and realization of cost savings and synergies from restructurings; significant litigation; risks associated with decisions to expend cash reserves for various uses in accordance with our capital allocation policy such as debt prepayment, stock repurchases, or acquisitions rather than to retain such cash for future needs; risks associated with our substantial leverage and restrictive covenants in our debt agreements that may be in place from time to time; risks associated with our worldwide operations including foreign employment and labor matters associated with unions and collective bargaining arrangements as well asman-made and/or natural disasters affecting our operations, or financial results; the threat or occurrence of international armed conflict and terrorist activities both in the United States and internationally; risks of changes in U.S. or international tax rates or legislation, including the impact of the new U.S. tax legislation; risks and costs associated with increased and new regulation of corporate governance and disclosure standards; risks related to new legal requirements; and risks involving environmental or other governmental regulation. Additional factors that could affect our future results or events are described from time to time in our SEC reports. Readers are cautioned not to place undue reliance on forward-looking statements. We assume no obligation to update such information, except as may be required by law.

You should carefully consider the trends, risks and uncertainties described below and other information in this Form10-K and subsequent reports filed with or furnished to the SEC before making any investment decision with respect to our securities. If any of the following trends, risks or uncertainties actually occurs or continues, our business, financial condition or operating results could be materially adversely affected, the trading prices of our securities could decline, and you could lose all or part of your investment.

Trends, Risks and Uncertainties Related to Our Business

The semiconductor industry is highly cyclical, and significant downturns or upturns in customer demand can materially adversely affect our business and results of operations.

The semiconductor industry is highly cyclical and, as a result, is subject to significant downturns and upturns in customer demand for semiconductors and related products. We cannot accurately predict the timing of future downturns and upturns in the semiconductor industry or how severe and prolonged these conditions might be. Significant downturns often occur in connection with, or in anticipation of, maturing product cycles (for semiconductors and for theend-user products in which they are used) or declines in general economic conditions and can result in reduced product demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices, any of which could materially adversely affect our operating results as a result of increased operating expenses outpacing decreased revenue, reduced margins, underutilization of our manufacturing capacity and/or asset impairment charges. On the other hand, significant upturns can cause us to be unable to satisfy demand in a timely and cost efficient manner. In the event of such an upturn, we may not be able to expand our workforce and operations in a sufficiently timely manner, procure adequate resources and raw materials, or locate suitable third-party suppliers to respond effectively to changes in demand for our existing products or to the demand for new products requested by our customers, and our business and results of operations could be materially and adversely affected.

23

Rapid innovation and short product life cycles in the semiconductor industry can result in price erosion of older products, which may materially adversely affect our business and results of operations.

The semiconductor industry is characterized by rapid innovation and short product life cycles, which often results in price erosion, especially with respect to products containing older technology. Products are frequently replaced by more technologically advanced substitutes and, as demand for older technology falls, the price at which such products can be sold drops, in some cases precipitously. In addition, our and our competitors’ excess inventory levels can accelerate general price erosion.

In order to continue to profitably supply older products, we must offset lower prices by reducing production costs, typically through improvements in process technology and production efficiencies. If we cannot advance our process technologies or improve our production efficiencies to a degree sufficient to maintain required margins, we will no longer be able to make a profit from the sale of older products. Moreover, we may not be able to cease production of older products, either due to contractual obligations or for customer relationship reasons and, as a result, may be required to bear a loss on such products for a sustained period of time. If reductions in our production costs fail to keep pace with reductions in market prices for the products we sell, our business and results of operations could be materially adversely affected.

We may be unable to successfully integrate new strategic acquisitions, which could materially adversely affect our business, results of operations and financial condition.

We have made, and may continue to make, strategic acquisitions and alliances that involve significant risks and uncertainties. Successful acquisitions and alliances in the semiconductor industry are difficult to accomplish because they require, among other things, efficient integration and aligning of product offerings and manufacturing operations and coordination of sales and marketing and research and development efforts, often in markets or regions in which we have less experience than others. Our decision to pursue an acquisition is based on, among other factors, our estimates of expected future earnings growth and potential cost savings. For example, we may anticipate rationalization of a combined infrastructure and savings through integration of a newly acquired business into our business, and our estimates could turn out to be incorrect. Risks related to successful integration of an acquisition include, but are not limited to: (1) the ability to integrate information technology and other systems; (2) unidentified issues not discovered in our due diligence; (3) customers responding by changing their existing business relationships with us or the acquired company; (4) diversion of management’s attention from our day to day operations; and (5) loss of key employees due to uncertainty about positions post-integration. In addition, we may incur unexpected costs, such as operating or restructuring costs (including severance payments to departing employees) or taxes resulting from the acquisition or integration of the newly acquired business. In the past, we have recorded goodwill impairment charges related to certain of our acquisitions as a result of such factors as significant underperformance relative to historical or projected future operating results. Missteps or delays in integrating our acquisitions, which could be caused by factors outside of our control, or our failure to realize the expected benefits of the acquisitions on the timeline we anticipate or at all, could materially adversely affect our results of operations and financial condition.

Depending on the level of our ownership interest in and the extent to which we can exercise control over the acquired business, we may be required by U.S. generally accepted accounting principles (“GAAP”) and SEC rules and regulations to consolidate newly acquired businesses into our consolidated financial statements. The acquired businesses may not have independent audited financial statements, such statements may not be prepared in accordance with GAAP or the acquired businesses may have financial controls and systems that are not compatible with our financial controls and systems, any of which could materially impair our ability to properly integrate such businesses into our consolidated financial statements on a timely basis. Any revisions to,

24

inaccuracies in or restatements of our consolidated financial statements due to accounting for our acquisitions could have a material adverse effect our financial condition and results of operations.

We may be unable to maintain manufacturing efficiency, which could have a material adverse effect on our results of operations.

We believe that our success materially depends on our ability to maintain or improve our current margin levels related to our manufacturing. Semiconductor manufacturing requires advanced equipment and significant capital investment, leading to high fixed costs which include depreciation expense. Manufacturing semiconductor components also involves highly complex processes that we and our competitors are continuously modifying to improve yields and product performance. In addition, impurities, waste or other difficulties in the manufacturing process can lower production yields. Our manufacturing efficiency is and will continue to be an important factor in our future profitability, and we cannot assure you that we will be able to maintain our manufacturing efficiency, increase manufacturing efficiency to the same extent as our competitors, or be successful in our manufacturing rationalization plans. If we are unable to utilize our manufacturing and testing facilities at expected levels, or if production capacity increases while revenues do not, the fixed costs and other operating expenses associated with these facilities will not be fully absorbed, resulting in higher average unit costs and lower gross profits, which could have a material adverse effect on our results of operations.

Downturns or volatility in general economic conditions could have a material adverse effect on our business and results of operations.

In recent years, worldwide semiconductor industry sales have tracked the impact of the financial crisis, subsequent recovery and persistent economic uncertainty. We believe that the state of economic conditions in the United States is particularly uncertain due to likely shifts in legislative and regulatory conditions concerning, among other matters, international trade and taxation, and that an uneven recovery or a renewed global downturn may put pressure on our sales due to reductions in customer demand as well as customers deferring purchases. Volatile and/or uncertain economic conditions can adversely impact sales and profitability and make it difficult for us and our competitors to accurately forecast and plan our future business activities. To the extent we incorrectly plan for favorable economic conditions that do not materialize or take longer to materialize than expected, we may face oversupply of our products relative to customer demand. In the past, reduced customer spending has driven us, and may in the future drive us and our competitors, to reduce product pricing, which results in a negative effect on gross profit. Moreover, volatility in revenues as a result of unpredictable economic conditions may alter our anticipated working capital needs and interfere with our short-term and long-term strategies. To the extent that our sales, profitability and strategies are negatively affected by downturns or volatility in general economic conditions, our business and results of operations may be materially adversely affected.

If our technologies are subject to claims of infringement on the IP rights of third parties, efforts to address such claims could have a material adverse effect on our results of operations.

We may from time to time be subject to claims that we may be infringing third-party IP rights. If necessary or desirable, we may seek licenses under such IP rights. However, we cannot assure you that we will obtain such licenses or that the terms of any offered licenses will be acceptable to us. The failure to obtain a license from a third party for IP we use could cause us to incur substantial liabilities or to suspend the manufacture or shipment of products or our use of processes requiring such technologies. Further, we may be subject to IP litigation, which could cause us to incur significant expense, materially adversely affect sales of the challenged product or

25

technologies and divert the efforts of our technical and management personnel, whether or not such litigation is resolved in our favor. In the event of an adverse outcome in any such litigation, we may be required to:

• pay substantial damages;

• indemnify customers or distributors;

• cease the manufacture, use, sale or importation of infringing products;

• expend significant resources to develop or acquirenon-infringing technologies;

• discontinue the use of processes; or

• obtain licenses, which may not be available on reasonable terms, to the infringing technologies.

There are several civil litigation proceedings with Power Integrations, Inc. (“PI”), many of which were pending prior to the Fairchild Transaction, and there are also over two dozen outstanding administrative proceedings between the parties at the United States Patent and Trademark Office (the “USPTO”) in which each party is challenging the validity of the other party’s patents. Please see Note 12: “Commitments and Contingencies” in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for a more detailed description of the litigation and related administrative matters with PI and other legal matters we are currently engaged in.

The outcome of IP litigation is inherently uncertain and, if not resolved in our favor, could materially and adversely affect our business, financial condition and results of operations.

Many of our facilities and processes are interdependent and an operational disruption at any particular facility could have a material adverse effect on our ability to produce many of our products, which could materially adversely affect our business and results of operations.

We utilize an integrated manufacturing platform in which multiple facilities may each produce one or more components necessary for the assembly of a single product. As a result of the necessary interdependence within our network of manufacturing facilities, an operational disruption at a facility toward thefront-end of our manufacturing process may have a disproportionate impact on our ability to produce many of our products. For example, our facility in Roznov, Czech Republic, manufactures silicon wafers used by a number of our facilities, and any operational disruption, natural orman-made disaster or other extraordinary event that impacted the Roznov facility would have a material adverse effect on our ability to produce a number of our products worldwide. In the event of a disruption at any such facility, we may be unable to effectively source replacement components on acceptable terms from qualified third parties, in which case our ability to produce many of our products could be materially disrupted or delayed. Conversely, many of our facilities are single source facilities that only produce one of ourend-products, and a disruption at any such facility would materially delay or cease production of the related product. In the event of any such operational disruption, we may experience difficulty in beginning production of replacement components or products at new facilities (for example, due to construction delays) or transferring production to other existing facilities (for example, due to capacity constraints or difficulty in transitioning to new manufacturing processes), any of which could result in a loss of future revenues and materially adversely affect our business and results of operations.

The failure to successfully implement cost reduction initiatives, including through restructuring activities, could materially adversely affect our business and results of operations.

From time to time, we have implemented cost reduction initiatives in response to significant downturns in our industry, including relocating manufacturing to lower cost regions, transitioning higher-cost external supply to

26

internal manufacturing, working with our material suppliers to lower costs, implementing personnel reductions and voluntary retirement programs, reducing employee compensation, temporary shutdowns of facilities with mandatory vacation and aggressively streamlining our overhead. In the past, we have recorded net restructuring charges to cover costs associated with our cost reduction initiatives. These costs have been primarily composed of employee separation costs (including severance payments) and asset impairments. We also often undertake restructuring activities and programs to improve our cost structure in connection with our business acquisitions, which can result in significant charges, including charges for severance payments to terminated employees and asset impairment charges.

We cannot assure you that our cost reduction and restructuring initiatives will be successfully or timely implemented or that they will materially and positively impact our profitability. Because our restructuring activities involve changes to many aspects of our business, the associated cost reductions could materially adversely impact productivity and sales to an extent we have not anticipated. Even if we fully execute and implement these activities and they generate the anticipated cost savings, there may be other unforeseeable and unintended consequences that could materially adversely impact our profitability and business, including unintended employee attrition or harm to our competitive position. To the extent that we do not achieve the profitability enhancement or other benefits of our cost reduction and restructuring initiatives that we anticipate, our results of operations may be materially adversely effected.

If we are unable to identify and make the substantial research and development investments required to remain competitive in our business, our business, financial condition and results of operations may be materially adversely affected.

The semiconductor industry requires substantial investment in research and development in order to develop and bring to market new and enhanced technologies and products. The development of new products is a complex and time-consuming process and often requires significant capital investment and lead time for development and testing. We cannot assure you that we will have sufficient resources to maintain the level of investment in research and development that is required to remain competitive. In addition, the lengthy development cycle for our products limits our ability to adapt quickly to changes affecting the product markets and requirements of our customers andend-users. There can be no assurance that we will win competitive bid selection processes, known as “design wins,” for new products. In addition, design wins do not guarantee that we will make customer sales or that we will generate sufficient revenue to recover design and development investments, as expenditures for technology and product development are generally made before the commercial viability for such developments can be assured. There is no assurance that we will realize a return on the capital expended to develop new products, that a significant investment in new products will be profitable or that we will have margins as high as we anticipate at the time of investment or have experienced historically. To the extent that we underinvest in our research and development efforts, or that our investments and capital expenditures in research and development do not lead to sales of new products, we may be unable to bring to market technologies and products that are attractive to our customers, and as a result our business, financial condition and results of operations may be materially adversely affected.

We may be unable to develop new products to satisfy changing customer demands or regulatory requirements, which may materially adversely affect our business and results of operations.

The semiconductor industry is characterized by rapidly changing technologies, evolving regulatory and industry standards and certifications, changing customer needs and frequent new product introductions. Our success is largely dependent on our ability to accurately predict, identify and adapt to changes affecting the requirements of our customers in a timely and cost-effective manner. Additionally, the emergence of new industry or regulatory

27

standards and certification requirements may adversely affect the demand for our products. We focus our independent new product development efforts on market segments and applications that we anticipate will experience growth, but there can be no assurance that we will be successful in identifying high-growth areas or develop products that meet industry standards or certification requirements in a timely manner. A fundamental shift in technologies, the regulatory climate or consumption patterns and preferences in our existing product markets or the product markets of our customers orend-users could make our current products obsolete, prevent or delay the introduction of new products that we planned to make or render our current or new products irrelevant to our customers’ needs. If our new product development efforts fail to align with the needs of our customers, including due to circumstances outside of our control like a fundamental shift in the product markets of our customers and end users or regulatory changes, our business and results of operations could be materially adversely affected.

Uncertainties regarding the timing and amount of customer orders could lead to excess inventory and write-downs of inventory that could materially adversely affect our financial condition and results of operations.

Our sales are typically made pursuant to individual purchase orders or customer agreements, and we generally do not have long-term supply arrangements with our customers requiring a commitment to purchase. Generally, our customers may cancel orders 30 days prior to shipment for standard products and 90 days for custom products without incurring a significant penalty. We routinely generate inventory based on customers’ estimates ofend-user demand for their products, which is difficult to predict. This difficulty may be compounded when we sell to OEMs indirectly through distributors or contract manufacturers, or both, as our forecasts for demand are then based on estimates provided by multiple parties, which may vary significantly. In addition, our customers may change their inventory practices on short notice for any reason. Furthermore, short customer lead times are standard in the industry due to overcapacity. The cancellation or deferral of product orders, the return of previously sold products, or overproduction of products due to the failure of anticipated orders to materialize could result in excess obsolete inventory, which could result in write-downs of inventory or the incurrence of significant cancellation penalties under our arrangements with our raw materials and equipment suppliers. Unsold inventory, canceled orders and cancellation penalties may materially adversely affect our results of operations, and inventory write-downs may materially adversely affect our financial condition.

If we do not have access to capital on favorable terms, on the timeline we anticipate, or at all, our financial condition and results of operations could be materially adversely affected.

We require a substantial amount of capital to meet our operating requirements and remain competitive. We routinely incur significant costs to implement new manufacturing and information technologies, to increase our productivity and efficiency, to upgrade equipment and to expand production capacity, and there can be no assurance that we will realize a return on the capital expended. We have incurred and may continue to incur material amounts of debt to fund these requirements. Significant volatility or disruption in the global financial markets may result in us not being able to obtain additional financing on favorable terms, on the timeline we anticipate, or at all, and we may not be able to refinance, if necessary, any outstanding debt when due, all of which could have a material adverse effect on our financial condition. Any inability to obtain additional funding on favorable terms, on the timeline we anticipate, or at all, may cause us to curtail our operations significantly, reduce planned capital expenditures and research and development, or obtain funds through arrangements that management does not currently anticipate, including disposing of our assets and relinquishing rights to certain technologies, the occurrence of any of which may significantly impair our ability to remain competitive. If our operating results falter, our cash flow or capital resources prove inadequate, or if interest rates increase significantly, we could face liquidity problems that could materially and adversely affect our results of operations and financial condition.

28

The semiconductor industry is highly competitive, and our inability to compete effectively could materially adversely affect our business and results of operations.

The semiconductor industry is highly competitive, and our ability to compete successfully depends on elements both within and outside of our control. We face significant competition within each of our product lines from major global semiconductor companies as well as smaller companies focused on specific market niches. Because our components are often building block semiconductors that, in some cases, are integrated into more complex ICs, we also face competition from manufacturers of ICs, ASICs and fully customized ICs, as well as from customers who develop their own IC products. In addition, companies not currently in direct competition with us may introduce competing products in the future.

Our inability to compete effectively could materially adversely affect our business and results of operations. Products or technologies developed by competitors that are larger and have more substantial research and development budgets, or that are smaller and more targeted in their development efforts, may render our products or technologies obsolete or noncompetitive. We also may be unable to market and sell our products if they are not competitive on the basis of price, quality, technical performance, features, system compatibility, customized design, innovation, availability, delivery timing and reliability. If we fail to compete effectively on developing strategic relationships with customers and customer sales and technical support, our sales and revenues may be materially adversely affected. Competitive pressures may limit our ability to raise prices, and any inability to maintain revenues or raise prices to offset increases in costs could have a significant adverse effect on our gross margin. Reduced sales and lower gross margins would materially adversely affect our business and results of operations.

The semiconductor industry has experienced rapid consolidation and our inability to compete with large competitors or failure to identify attractive opportunities to consolidate may materially adversely affect our business.

The semiconductor industry is characterized by the high costs associated with developing marketable products and manufacturing technologies as well as high levels of investment in production capabilities. As a result, the semiconductor industry has experienced, and may continue to experience, significant consolidation among companies and vertical integration among customers. Larger competitors resulting from consolidations may have certain advantages over us, including, but not limited to: substantially greater financial and other resources with which to withstand adverse economic or market conditions and pursue development, engineering, manufacturing, marketing and distribution of their products; longer independent operating histories; presence in key markets; patent protection; and greater name recognition. In addition, we may be at a competitive disadvantage to our peers if we fail to identify attractive opportunities to acquire companies to expand our business. Consolidation among our competitors and integration among our customers could erode our market share, negatively impact our capacity to compete and require us to restructure our operations, any of which would have a material adverse effect on our business.

Natural disasters and other business disruptions could cause significant harm to our business operations and facilities and could adversely affect our supply chain and our customer base, any of which may materially adversely affect our business, results of operation, and financial condition.

Our U.S. and international manufacturing facilities and distribution centers, as well as the operations of our third-party suppliers, are susceptible to losses and interruptions caused by floods, hurricanes, earthquakes, typhoons, and similar natural disasters, as well as power outages, telecommunications failures, industrial accidents, and similar events. The occurrence of natural disasters in any of the regions in which we operate could severely

29

disrupt the operations of our businesses by negatively impacting our supply chain, our ability to deliver products, and the cost of our products. Such events can negatively impact revenues and earnings and can significantly impact cash flow, both from decreased revenue and from increased costs associated with the event. In addition, these events could cause consumer confidence and spending to decrease or result in increased volatility to the U.S. and worldwide economies. Although we carry insurance to generally compensate for losses of the type noted above, such insurance may not be adequate to cover all losses that may be incurred or continue to be available in the affected area at commercially reasonable rates and terms. To the extent any losses from natural disasters or other business disruptions are not covered by insurance, any costs, write-downs, impairments and decreased revenues can materially adversely affect our business, our results of operations and our financial condition.

The loss of one of our largest customers, or a significant reduction in the revenue we generate from these customers, could materially adversely affect our revenues, profitability, and results of operations.

Product sales to our ten largest customers have historically accounted for a significant amount of our business. For instance, for the years ended December 31, 2017 and 2016, revenue from our 10 largestend-customers collectively represented approximately 24% and 24%, respectively, of our total revenues for those years. Many of our customers operate in cyclical industries, and, in the past, we have experienced significant fluctuations from period to period in the volume of our products ordered. Generally, our agreements with our customers impose no minimum or continuing obligations to purchase our products. We cannot assure you that our largest customers will not cease purchasing products from us in favor of products produced by other suppliers, significantly reduce orders or seek price reductions in the future, and any such event could have a material adverse effect on our revenues, profitability, and results of operations.

Because a significant portion of our revenue is derived from customers in the automotive, industrial and communications industries, a downturn or lower sales to customers in either industry could materially adversely affect our business and results of operations.

A significant portion of our sales are to customers within the automotive, industrial (including medical, aerospace and defense) and communications industries (including networking). Sales into these industries represented approximately 31%, 25%, and 20% of our revenue, respectively, for the year ended December 31, 2017, and those percentages will vary from quarter to quarter. Each of the automotive, industrial and communications industries is cyclical, and, as a result, our customers in these industries are sensitive to changes in general economic conditions, disruptive innovation andend-market preferences, which can adversely affect sales of our products and, correspondingly, our results of operations. Additionally, the quantity and price of our products sold to customers in these industries could decline despite continued growth in their respective end markets. Lower sales to customers in the automotive, industrial or communications industry may have a material adverse effect on our business and results of operations.

Shortages or increased prices of raw materials could materially adversely affect our results of operations.

Our manufacturing processes rely on many raw materials, including various chemicals and gases, polysilicon, silicon wafers, aluminum, gold, silver, copper, lead frames, mold compound and ceramic packages. Generally, our agreements with suppliers of raw materials impose no minimum or continuing supply obligations, and we obtain our raw materials and supplies from a large number of sources on ajust-in-time basis. From time to time, suppliers of raw materials may extend lead times, limit supplies or increase prices due to capacity constraints or other factors beyond our control. Shortages could occur in various essential raw materials due to interruption of supply or increased demand. If we are unable to obtain adequate supplies of raw materials in a timely manner,

30

the costs of our raw materials increases significantly, their quality deteriorates or they give rise to compatibility or performance issues in our products, our results of operations could be materially adversely affected.

We are dependent on the services of third-party suppliers and contract manufacturers, and any disruption in or deterioration of the quality of the services delivered by such third parties could materially adversely affect our business and results of operations.

We use third-party contractors for certain of our manufacturing activities, primarily wafer fabrication and the assembly and testing of final goods. Our agreements with these manufacturers typically require us to commit to purchase services based on forecasted product needs, which may be inaccurate, and, in some cases, require longer-term commitments. We are also dependent upon a limited number of highly specialized third-party suppliers for required components and materials for certain of our key technologies. Arranging for replacement manufacturers and suppliers can be time consuming and costly, and the number of qualified alternative providers can be extremely limited. Our business operations, productivity and customer relations could be materially adversely affected if these contractual relationships were disrupted or terminated, the cost of such services increased significantly, the quality of the services provided deteriorated or our forecasted needs proved to be materially incorrect.

Our international operations subject us to risks inherent in doing business on an international level that could adversely impact our business, financial condition and results of operations.

A significant amount of our total revenue outside of the U.S. is derived from the Asia/Pacific region and Europe, and we maintain significant operations in these regions. In addition, we rely on a number of contract manufacturers whose operations are primarily located in the Asia/Pacific region. Risks inherent in doing business on an international level include, among others, the following:

• economic and geopolitical instability (including as a result of the threat or occurrence of armed international conflict or terrorist attacks);

• changes in regulatory requirements, international trade agreements, tariffs, customs, duties and other trade barriers;

• licensing requirements for the import or export of certain products;

• exposure to different legal standards, customs, business practices, tariffs, duties and other trade barriers, including changes with respect to price protection, competition practices, IP, anti-corruption and environmental compliance, trade and travel restrictions, pandemics, import and export license requirements and restrictions, and accounts receivable collections;

• transportation and other supply chain delays and disruptions;

• power supply shortages and shutdowns;

• fluctuations in raw material costs and energy costs;

• difficulties in staffing and managing foreign operations, including collective bargaining agreements and workers councils, exposure to foreign labor laws and other employment and labor issues;

• currency fluctuations;

• currency convertibility and repatriation;

• taxation of our earnings and the earnings of our personnel;

• limitations on the repatriation of earnings and potential taxation of foreign profits in the U.S.;

• potential violations by our international employees or third party agents of international or U.S. laws relevant to foreign operations (e.g., the Foreign Corrupt Practices Act (“FCPA”));

• difficulty in enforcing intellectual property rights; and

31

• other risks relating to the administration of or changes in, or new interpretations of, the laws, regulations and policies of the jurisdictions in which we conduct our business.

We cannot assure you that we will be successful in overcoming the risks that relate to or arise from operating in international markets, the materialization of any of which could materially adversely affect our business, financial condition and results of operations.

We could be subject to changes in tax rates or the adoption of new U.S. or international tax legislation or have exposure to additional tax liabilities, which could adversely affect our results of operations or financial condition.

Changes to income tax regulations in the United States and the jurisdictions in which we operate, or in the interpretation of such laws, could, under our existing tax structure, significantly increase our effective tax rate and ultimately reduce our cash flow from operating activities and otherwise have a material adverse effect on our financial condition. In addition, other factors or events, including business combinations and investment transactions, changes in the valuation of our deferred tax assets and liabilities, adjustments to income taxes upon finalization of various tax returns or as a result of deficiencies asserted by taxing authorities, increases in expenses not deductible for tax purposes, changes in available tax credits, increasing operations in high tax jurisdictions, and changes in tax rates, could also increase our future effective tax rate.

Our tax filings are subject to review or audit by the Internal Revenue Service (the “IRS”) and state, local and foreign taxing authorities. We exercise significant judgment in determining our worldwide provision for income taxes and, in the ordinary course of our business, there may be transactions and calculations where the ultimate tax determination is uncertain. We are also liable for potential tax liabilities of businesses we acquire. The final determination in an audit may be materially different than the treatment reflected in our historical income tax provisions and accruals. An assessment of additional taxes because of an audit could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Further changes in the tax laws of foreign jurisdictions could arise as a result of the base erosion and profit shifting project that was undertaken by the Organization for EconomicCo-operation and Development (“OECD”). The OECD, which represents a coalition of member countries, recommended changes to numerous long-standing tax principles. These changes, if adopted by countries, could increase tax uncertainty and may adversely affect our provision for income taxes.

The impact of new U.S. tax legislation is uncertain and could have a material adverse impact on our cash flows and results of operations.

On December 22, 2017, the U.S. enacted comprehensive tax legislation, H.R.1, commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code, and it will take time for additional clarifying guidance and legislation to be issued, and this guidance will be required for the interpretation of these comprehensive changes. Based on our current understanding of the law following a preliminary review, we estimated significant impacts to our fourth quarter and full year 2017 earnings. The impact of the Tax Act may differ from this estimate, possibly materially, due to, among other things, changes in interpretations and assumptions the Company has made, guidance that may be issued and actions the Company may take as a result of the Tax Act.

The Tax Act could have a material benefit or material adverse impact and could result in volatility in our effective tax rate, tax expense and cash flow. We are in the process of analyzing the potential aggregate current

32

and future impacts of the Tax Act relative to how we do business, cash flows and results of operations. Any benefit associated with the lower U.S. corporate tax rate could be reduced or outweighed by other adverse changes enacted in the Tax Act or by the cost of compliance.

We operate a global business through numerous foreign subsidiaries, and there is a risk that tax authorities will challenge our transfer pricing methodologies and/or legal entity structures, which could adversely affect our operating results and financial condition.

We conduct operations worldwide through our foreign subsidiaries and are, therefore, subject to complex transfer pricing regulations in the jurisdictions in which we operate. Transfer pricing regulations generally require that, for tax purposes, transactions between related parties be priced on a basis that would be comparable to an arm’s length transaction between unrelated parties. There is uncertainty and inherent subjectivity in complying with these rules. To the extent that any foreign tax authorities disagree with our transfer pricing policies, we could become subject to significant tax liabilities and penalties. The ultimate outcome of a tax examination could differ materially from our provisions and could have a material adverse effect on our business, financial condition, results or operations and cash flows.

Our legal organizational structure could result in unanticipated unfavorable tax or other consequences which could have a material adverse effect on our financial condition and results of operations. Changes in tax laws, regulations, future jurisdictional profitability of us and our subsidiaries, and related regulatory interpretations in the countries in which we operate may impact the taxes we pay or tax provision we record, which could have a material adverse effect on our results of operations. In addition, any challenges to how our entities are structured or realigned or their business purpose by taxing authorities could result in us becoming subject to significant tax liabilities and penalties which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Currency fluctuations, changes in foreign exchange regulations and repatriation delays and costs could have a material adverse effect on our results of operations and financial condition.

We have sizeable sales and operations in the Asia/Pacific region and Europe and a significant amount of this business is transacted in currency other than U.S. dollars. In addition, while a significant percentage of our cash and cash equivalents is held outside the U.S., many of our liabilities, including our outstanding indebtedness, and certain other cash payments, such as share repurchases, are payable in U.S. dollars. As a result, currency fluctuations and changes in foreign exchange regulations can have a material adverse effect on our liquidity and financial condition.

In addition, repatriation of funds held outside the U.S. could have adverse tax consequences and could be subject to delay due to required local country approvals or local obligations. From time to time, we are required to make cash deposits outside of the U.S. to support bank guarantees of our obligations under certain office leases or amounts we owe to certain vendors and such cash deposits are not available for other uses as long as the related bank guarantees are outstanding. Foreign exchange regulations may also limit our ability to convert or repatriate foreign currency. As a result of having a lower amount of cash and cash equivalents in the U.S., our financial flexibility may be reduced, which could have a material adverse effect on our ability to make interest and principal payments due under our various debt obligations. Restrictions on repatriation or the inability to use cash held abroad to fund our operations in the U.S. may have a material adverse effect on our liquidity and financial condition.

We may be unable to attract and retain highly skilled personnel.

Our success depends on our ability to attract, motivate and retain highly skilled personnel, including technical, marketing, management and staff personnel, both in the U.S. and internationally. In the semiconductor industry, the competition for qualified personnel, particularly experienced design engineers and other technical employees, is intense, particularly when the business cycle is improving. During such periods, competitors may try to recruit our most valuable technical employees. While we devote a great deal of our attention to designing competitive compensation programs aimed at attracting and retaining personnel, specific elements of our compensation programs may not be competitive with those of our competitors, and there can be no assurance that we will be able to retain our current personnel or recruit the key personnel we require. Loss of the services of, or failure to effectively recruit, qualified personnel, including senior managers, could have a material adverse effect on our competitive position and on our business.

If we must reduce our use of equity awards to compensate our employees, our competitiveness in the employee marketplace could be adversely affected and our results of operations could vary as a result of changes in our stock-based compensation programs.

We have issued in the past, and expect to continue to issue, RSUs with time-based vesting, performance-based awards and common stock options that generally have exercise prices at the market value at the time of the grant and that are subject to vesting over time as compensation tools. While this is a routine practice in many parts of the world, foreign exchange and income tax regulations in some countries make this practice more and more difficult. Such regulations tend to diminish the value of equity compensation to our employees in those countries. Our current practice is to seek stockholder approval of new, or amendments to existing, equity compensation plans. If these proposals do not receive stockholder approval, we may not be able to grant equity awards to employees at the same levels as in the past, which could materially adversely affect our ability to attract, retain and motivate qualified personnel, thereby materially adversely affecting our business. In addition, changes in forecasted stock-based compensation expense could cause our results of operations to vary by impacting our gross margin percentage, research and development expenses, marketing, general and administrative expenses and our tax rate.

Disruptions caused by labor disputes or organized labor activities could materially harm our business and reputation.

Currently, certain of our U.S. employees in Pennsylvania are represented by labor unions. In addition, we may from time to time experience union organizing activities in ournon-union facilities. Disputes with the current labor union or new union organizing activities could lead to production slowdowns or stoppages and make it difficult or impossible for us to meet scheduled delivery times for product shipments to our customers, which could result in a loss of business and material damage to our reputation. In addition, union activity and compliance with international labor standards could result in higher labor costs, which could have a material adverse effect on our financial position and results of operations.

If we are unable to protect the intellectual property we use, our business, results of operations and financial condition could be materially adversely affected.

The enforceability of our patents, trademarks, copyrights, software licenses and other IP is uncertain in certain circumstances. Effective IP protection may be unavailable, limited or not applied for in the U.S. and internationally. The various laws and regulations governing our registered and unregistered IP assets, patents,

34

trade secrets, trademarks, mask works and copyrights to protect our products and technologies are subject to legislative and regulatory change and interpretation by courts. With respect to our IP generally, we cannot assure you that:

• any of the substantial number of U.S. or foreign patents and pending patent applications that we employ in our business will not lapse or be invalidated, circumvented, challenged, abandoned or licensed to others;

• any of our pending or future patent applications will be issued or have the coverage originally sought;

• any of the trademarks, copyrights, trade secrets,know-how or mask works that we employ in our business will not lapse or be invalidated, circumvented, challenged, abandoned or licensed to others; or

• any of our pending or future trademark, copyright, or mask work applications will be issued or have the coverage originally sought.

When we seek to enforce our rights, we are often subject to claims that the IP right is invalid, is otherwise not enforceable or is licensed to the party against whom we are asserting a claim. In addition, our assertion of IP rights often results in the other party seeking to assert alleged IP rights of its own against us, which may materially adversely impact our business. An unfavorable ruling in these sorts of matters could include money damages or an injunction prohibiting us from manufacturing or selling one or more products, which could in turn negatively affect our business, results of operations or cash flows.

In addition, some of our products and technologies are not covered by any patents or pending patent applications. We seek to protect our proprietary technologies, including technologies that may not be patented or patentable, in part by confidentiality agreements and, if applicable, inventors’ rights agreements with our collaborators, advisors, employees and consultants. We cannot assure you that these agreements will not be breached, that we will have adequate remedies for any breach or that persons or institutions will not assert rights to IP arising out of our research. Should we be unable to protect our IP, competitors may develop products or technologies that duplicate our products or technologies, benefit financially from innovations for which we bore the costs of development and undercut the sales and marketing of our products, all of which could have a material adverse effect on our business, results of operations and financial condition.

Environmental and health and safety liabilities and expenditures could materially adversely affect our results of operations and financial condition.

Our manufacturing operations are subject to various environmental laws and regulations relating to the management, disposal and remediation of hazardous substances and the emission and discharge of pollutants into the air, water and ground, and we have been identified as either a primary responsible party or a potentially responsible party at sites where we or our predecessors operated or disposed of waste in the past. Our operations are also subject to laws and regulations relating to workplace safety and worker health, which, among other requirements, regulate employee exposure to hazardous substances. We have indemnities from third parties for certain environmental and health and safety liabilities for periods prior to our operations at some of our current and past sites, and we have also purchased environmental insurance to cover certain claims related to historical contamination and future releases of hazardous substances. However, we cannot assure you that such indemnification arrangements and insurance will cover any or all of our material environmental costs. In addition, the nature of our operations exposes us to the continuing risk of environmental and health and safety liabilities including:

• changes in U.S. and international environmental or health and safety laws or regulations, including, but not limited to, future laws or regulations imposed in response to climate change concerns;

35

• the manner in which environmental or health and safety laws or regulations will be enforced, administered or interpreted;

• our ability to enforce and collect under indemnity agreements and insurance policies relating to environmental liabilities;

• the cost of compliance with future environmental or health and safety laws or regulations or the costs associated with any future environmental claims, including the cost ofclean-up of currently unknown environmental conditions; or

• the cost of fines, penalties or other legal liability, should we fail to comply with environmental or health and safety laws or regulations.

To the extent that we face unforeseen environmental or health and safety compliance costs or remediation expenses or liabilities that are not covered by indemnities or insurance, we may bear the full effect of such costs, expense and liabilities, which could materially adversely affect our results of operations and financial condition.

We are exposed to increased costs and risks associated with complying with increasing and new regulation of corporate governance and disclosure standards.

Like most publicly traded companies, we incur significant cost and spend a significant amount of management time and internal resources to comply with changing laws, regulations and standards relating to corporate governance and public disclosure, which requires management’s annual review and evaluation of our internal control over financial reporting and attestations of the effectiveness of these systems by our management and by our independent registered public accounting firm. As we continue to make strategic acquisitions, mergers and alliances, the integration of these businesses increases the complexity of our systems of controls. While we devote significant resources and time to comply with the internal control over financial reporting requirements under Section 404 of the Sarbanes-Oxley Act of 2002 (“SOX”), we cannot be certain that these measures will ensure that we design, implement and maintain adequate control over our financial process and reporting in the future.

There can be no assurance that we or our independent registered public accounting firm will not identify a material weakness in the combined company’s internal control over financial reporting in the future. Failure to comply with SOX, including delaying or failing to successfully integrate our acquisitions into our internal control over financial reporting or the identification and reporting of a material weakness, may cause investors to lose confidence in our consolidated financial statements or even in our ability to recognize the anticipated synergies and benefits of such transactions, and the trading price of our common stock or other securities may decline. In addition, if we fail to remedy any material weakness, our investors and others may lose confidence in our financial statements, our financial statements may be materially inaccurate, our access to capital markets may be restricted and the trading price of our common stock may decline.

Warranty claims, product liability claims and product recalls could harm our business, results of operations and financial condition.

Manufacturing semiconductors is a highly complex and precise process, requiring production in a tightly controlled, clean environment. Minute impurities in our manufacturing materials, contaminants in the manufacturing environment, manufacturing equipment failures, and other defects can cause our products to benon-compliant with customer requirements or otherwise nonfunctional. We face an inherent business risk of exposure to warranty and product liability claims in the event that our products fail to perform as expected or such failure of our products results, or is alleged to result, in bodily injury or property damage (or both). In addition, if any of our designed products are or are alleged to be defective, we may be required to participate in

36

their recall. As suppliers become more integrally involved in electrical design, OEMs are increasingly expecting them to warrant their products and are increasingly looking to them for contributions when faced with product liability claims or recalls. A successful warranty or product liability claim against us in excess of our available insurance coverage, if any, and established reserves, or a requirement that we participate in a product recall, could have material adverse effects on our business, results of operations and financial condition. Additionally, in the event that our products fail to perform as expected or such failure of our products results in a recall, our reputation may be damaged, which could make it more difficult for us to sell our products to existing and prospective customers and could materially adversely affect our business, results of operations and financial condition.

Since a defect or failure in our product could give rise to failures in the goods that incorporate them (and claims for consequential damages against our customers from their customers), we may face claims for damages that are disproportionate to the revenues and profits we receive from the products involved. In certain instances, we attempt to limit our liability through our standard terms and conditions of sale and other customer contracts. There is no assurance that such limitations will be effective, and to the extent that we are liable for damages in excess of the revenues and profits we received from the products involved, our results of operations and financial condition could be materially adversely affected.

We may be subject to disruptions or breaches of our secured network that could irreparably damage our reputation and our business, expose us to liability and materially adversely affect our results of operations.

We routinely collect and store sensitive data, including IP and other proprietary information about our business and our customers, suppliers and business partners. The secure processing, maintenance and transmission of this information is critical to our operations and business strategy. We may be subject to disruptions or breaches of our secured network caused by computer viruses, illegal hacking, criminal fraud or impersonation, acts of vandalism or terrorism or employee error. Our security measures and/or those of our third party service providers and/or customers may not detect or prevent such security breaches. The costs to us to reduce the risk of or alleviate cyber security breaches and vulnerabilities could be significant, and our efforts to address these problems may not be successful and could result in interruptions and delays that may materially impede our sales, manufacturing, distribution or other critical functions. Any such compromise of our information security could result in the misappropriation or unauthorized publication of our confidential business or proprietary information or that of other parties with which we do business, an interruption in our operations, the unauthorized transfer of cash or other of our assets, the unauthorized release of customer or employee data or a violation of privacy or other laws. In addition, computer programmers and hackers also may be able to develop and deploy viruses, worms and other malicious software programs that attack our products, or that otherwise exploit any security vulnerabilities, and any such attack, if successful, could expose us to liability to customer claims. Any of the foregoing could irreparably damage our reputation and business, which could have a material adverse effect on our results of operations.

Sales through distributors and other third parties expose us to risks that, if realized, could have a material adverse effect on our results of operations.

We face risks related to our sale of a significant, and increasing, portion of our products through distributors. Distributors may sell products that compete with our products, and we may need to provide financial and other incentives to focus distributors on the sale of our products. We may rely on one or more key distributors for a product, and the loss of these distributors could reduce our revenue. Distributors may face financial difficulties, including bankruptcy, which could harm our collection of accounts receivable and financial results. Violations of the FCPA or similar laws by distributors or other third-party intermediaries could have a material impact on our

37

business. Failure to manage risks related to our use of distributors may reduce sales, increase expenses, and weaken our competitive position, any of which could have a material adverse effect on our results of operations.

The failure to comply with the terms and conditions of our contracts could result in, among other things, damages, fines or other liabilities.

We have a diverse customer base consisting of both private sector clients and public sector clients, including the U.S. government. Sales to our private sector clients are generally based on stated contractual terms, the terms and conditions on our website or terms contained in purchase orders on atransaction-by-transaction basis. Sales to our public sector clients are generally derived from sales to federal, state and local governmental departments and agencies through various contracts and programs which may require compliance with regulations covering many areas of our operations, including, but not limited to, accounting practices, IP rights, information handling, and security. Noncompliance with contract terms, particularly with respect to highly-regulated public sector clients, or with government procurement regulations could result in fines or penalties against us, termination of such contracts or civil, criminal and administrative liability to the Company. With respect to public sector clients, the government’s remedies may also include suspension or debarment from future government business. In addition, almost all of our contracts have default provisions, and certain of our contracts in the public sector are terminable at any time for convenience of the contracting agency. The effect of any of these possible actions or the adoption of new or modified procurement regulations or practices could materially adversely affect our business, financial position and results of operations.

The Company is subject to governmental laws, regulations and other legal obligations related to privacy and data protection.

The legislative and regulatory framework for privacy and data protection issues worldwide is rapidly evolving and is likely to remain uncertain for the foreseeable future. The Company collects personally identifiable information (“PII”) and other data as part of its business processes and activities. This data is subject to a variety of U.S. and international laws and regulations, including oversight by various regulatory or other governmental bodies. Many foreign countries and governmental bodies, including the European Union and other relevant jurisdictions where the Company conducts business, have laws and regulations concerning the collection and use of PII and other data obtained from their residents or by businesses operating within their jurisdictions that are currently more restrictive than those in the U.S. Additionally, in May 2016, the European Union adopted the General Data Protection Regulation that will impose more stringent data protection requirements and will provide for greater penalties for noncompliance beginning in May 2018. While the Company has developed and is executing plans to meet these requirements, these plans are subject to many variables that could delay or otherwise affect implementation. Any inability, or perceived inability, to adequately address privacy and data protection concerns, even if unfounded, or to comply with applicable laws, regulations, policies, industry standards, contractual obligations or other legal obligations, could result in additional cost and liability to the Company or company officials, damage our reputation, inhibit sales and adversely affect our business.

Trends, Risks and Uncertainties Relating to Our Indebtedness

Our substantial debt could materially adversely affect our financial condition and results of operations.

As of December 31, 2017, we had $3,175.0 million of outstanding indebtedness. We may need to incur additional indebtedness in the future to repay or refinance other outstanding debt, to make acquisitions or for

38

other purposes, and if we incur additional debt, the related risks that we now face could intensify. The degree to which we are leveraged could have important consequences to our potential and current investors, including:

• our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, general corporate purposes or other purposes may be impaired;

• the timing, amount and execution of our capital allocation policy, including our share repurchase program, could be affected by the degree to which we are leveraged;

• a significant portion of our cash flow from operating activities must be dedicated to the payment of interest and principal on our debt, which reduces the funds available to us for our operations and may limit our ability to engage in acts that may be in our long-term best interests;

• some of our debt is and will continue to be at variable rates of interest, which may result in higher interest expense in the event of increases in market interest rates;

• our debt agreements may contain, and any agreements to refinance our debt likely will contain, financial and restrictive covenants, and our failure to comply with them may result in an event of default which if not cured or waived, could have a material adverse effect on us;

• our level of indebtedness will increase our vulnerability to, and reduce our flexibility to respond to, general economic downturns and adverse industry and business conditions;

• as our long-term debt ages, we must repay, and may need to renegotiate, such debt or seek additional financing;

• to the extent the debt we incur requires collateral to secure such indebtedness, our assets could be at risk and our flexibility related to such assets could be limited;

• our debt service obligations could limit our flexibility in planning for, or reacting to, changes in our business and the semiconductor industry;

• our substantial leverage could place us at a competitive disadvantagevis-à-vis our competitors who may have less leverage relative to their overall capital structures; and

• our level of indebtedness may place us at a competitive disadvantage relative to less leveraged competitors.

To the extent that we continue to maintain or expand our significant indebtedness, our financial condition and results of operations may be materially adversely affected.

Indebtedness incurred in connection with the Fairchild Transaction could materially and adversely affect us by, among other things, limiting our ability to conduct our operations and reducing our flexibility to respond to changing business and economic conditions.

In connection with our acquisition of Fairchild, we entered into the Amended Credit Agreement providing for our $1.0 billion Revolving Credit Facility, which provides liquidity to us, and the $2.4 billion Term Loan “B” Facility, which was used to fund the acquisition of Fairchild. The obligations under the Amended Credit Agreement are collateralized by a lien on substantially all of the personal property and material real property assets of the Company and most of the Company’s domestic subsidiaries. As a result, if we are unable to satisfy our obligations under the Amended Credit Agreement, the lenders could take possession of and foreclose on the pledged collateral securing the indebtedness, in which case we would be at risk of losing the related collateral, which would have a material adverse effect on our business and operations. In addition, subject to customary exceptions, the Amended Credit Agreement requires mandatory prepayment under certain circumstances, which may result in prepaying outstanding amounts under the Revolving Credit Facility and the Term Loan “B” Facility rather than using funds for other business purposes. Our acquisition-related financing could have a material adverse effect on our business and financial condition, including, among other things, our ability to obtain

39

additional financing for working capital, capital expenditures, acquisitions, and other general corporate purposes and could reduce our flexibility to respond to changing business and economic conditions.

The agreements relating to our indebtedness, including the Amended Credit Agreement, may restrict our ability to operate our business, and as a result may materially adversely affect our results of operations.

Our debt agreements, including the Amended Credit Agreement, contain, and any future debt agreements may include, a number of restrictive covenants that impose significant operating and financial restrictions on us and our subsidiaries. Such restrictive covenants may significantly limit our ability to:

• incur additional debt, including issuing guarantees;

• incur liens;

• make certain investments;

• settle a conversion of our 1.00% and 1.625% Notes in whole or in part with cash;

• sell or otherwise dispose of assets;

• make some acquisitions;

• engage in mergers or consolidations or certain other “change of control” transactions;

• make distributions to our stockholders;

• engage in restructuring activities;

• engage in certain sale and leaseback transactions; and

• issue or repurchase stock or other securities.

Such agreements may also require us to satisfy other requirements, including maintaining certain financial ratios and condition tests. Our ability to meet these requirements can be affected by events beyond our control, and we may be unable to meet them. To the extent we fail to meet any such requirements and are in default under our debt obligations, our financial condition may be materially adversely affected. These restrictions may limit our ability to engage in activities that could otherwise benefit us. To the extent that we are unable to engage in activities that support the growth, profitability and competitiveness of our business, our results of operations may be materially adversely affected.

We may not be able to generate sufficient cash flow to meet our debt service obligations, and any inability to repay our debt when due would have a material adverse effect on our business, financial condition and results of operations.

Our ability to generate sufficient cash flow from operating activities to make scheduled payments on our debt obligations will depend on our future financial performance, which will be affected by a range of economic, competitive and business factors, many of which are outside of our control. If we do not generate sufficient cash flow from operating activities and proceeds from sales of assets in the ordinary course of business to satisfy our debt obligations as they come due, we may have to undertake alternative financing plans, such as refinancing or restructuring our debt, selling additional assets, reducing or delaying capital investments or seeking to raise additional capital. We cannot assure you that any refinancing would be possible, that any assets could be sold, or, if sold, of the timing of the sales and the amount of proceeds realized from those sales, or that additional financing could be obtained on acceptable terms, if at all, or would be permitted under the terms of our various debt instruments then in effect. Furthermore, we cannot assure you that, if we were required to repurchase any of our debt securities upon a change of control or other specified event, our assets or cash flow would be sufficient to fully repay borrowings under our outstanding debt instruments or that we would be able to refinance or restructure the payments on those debt securities. If we are unable to repay, refinance or restructure our indebtedness under our collateralized debt, the holders of such debt could proceed against the collateral securing

40

that indebtedness, which could materially negatively impact our results of operations and financial condition. A default under our committed credit facilities, including our Amended Credit Agreement, could also limit our ability to make further borrowings under those facilities, which could materially adversely affect our business and results of operations. In addition, to the extent we are not able to borrow or refinance debt obligations, we may have to issue additional shares of our common stock, which would have a dilutive effect to the current stockholders.

An event of default under any agreement relating to our outstanding indebtedness could cross default other indebtedness, which could have a material adverse effect on our business, financial condition and results of operations.

If there were an event of default under any of the agreements relating to our outstanding indebtedness, the holders of the defaulted debt could cause all amounts outstanding with respect to that debt to be due and payable immediately, which default or acceleration of debt could cross default other indebtedness. Any such cross default would put immediate pressure on our liquidity and financial condition and would amplify the risks described above with regards to being unable to repay our indebtedness when due and payable. We cannot assure you that our assets or cash flow would be sufficient to fully repay borrowings under our outstanding debt instruments if accelerated upon an event of default, and, as described above, any inability to repay our debt when due would have a material adverse effect on our business, financial condition and results of operations.

If our operating subsidiaries, which may have no independent obligation to repay our debt, are not able to make cash available to us for such repayment, our business, financial condition and results of operations may be adversely affected.

We conduct our operations through our subsidiaries. Repayment of our indebtedness is dependent on the generation of cash flow by our subsidiaries and their ability to make such cash available to us, by dividend, debt repayment or otherwise. Unless they are guarantors of our indebtedness, our subsidiaries have no obligation to pay amounts due on such indebtedness or to make funds available for that purpose. Our subsidiaries may not be able to, or may not be permitted to, make distributions to enable us to make payments in respect of our indebtedness. Each subsidiary is a distinct legal entity, and, under certain circumstances, legal and contractual restrictions may limit our ability to obtain cash from our subsidiaries. In the event that we do not receive distributions or payments from our subsidiaries, we may be unable to make required principal and interest payments on our indebtedness and, as described above, any inability to repay our debt when due would have a material adverse effect on our business, financial condition and results of operations.

If interest rates increase, our debt service obligations under our variable rate indebtedness could increase significantly, which would have a material adverse effect on our results of operations.

Borrowings under certain of our facilities from time to time, including under our Amended Credit Agreement, are at variable rates of interest and as a result expose us to interest rate risk. If interest rates were to increase, our debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. During the first quarter of 2017, we entered into interest rate swaps that involved the exchange of floating for fixed rate interest payments in order to reduce interest rate volatility for a portion of our Term Loan “B” Facility. However, we may not maintain interest rate swaps with respect to all of our variable rate indebtedness, and any swaps we enter into may not fully mitigate our interest rate risk. To the extent the risk materializes and is not fully mitigated, the resulting increase in interest expense could have a material adverse effect on our results of operations.

41

Servicing the 1.00% Notes and 1.625% Notes may require a significant amount of cash, and we may not have sufficient cash flow or the ability to raise the funds necessary to satisfy our obligations under the 1.00% Notes and 1.625% Notes in a timely manner.

In June 2015, we issued $690.0 million aggregate principal amount of our 1.00% Notes, and in March 2017, we issued $575.0 million aggregate principal amount of our 1.625% Notes. Holders of the 1.00% Notes and the 1.625% Notes will have the right to require us to repurchase all or a portion of their notes upon the occurrence of a fundamental change (as defined under the respective indentures governing such notes) at a repurchase price equal to 100% of their principal amount, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date. In addition, upon conversion of the 1.00% Notes and/or the 1.625% Notes to be repurchased, unless we elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional shares), we will be required to make cash payments in respect of such 1.00% Notes and/or 1.625% Notes being converted. Moreover, we will be required to repay the 1.00% Notes and the 1.625% Notes in cash at their maturity, unless earlier converted or repurchased. Servicing the 1.00% Notes and the1.625% Notes may require a significant amount of cash, and we may not have sufficient cash flow or the ability to raise the funds necessary to satisfy our obligations under the 1.00% Notes and the 1.625% Notes. Our ability to make cash payments in connection with conversions of the 1.00% Notes and/or the 1.625% Notes, repurchase the 1.00% Notes and/or the 1.625% Notes in the event of a fundamental change or repay such notes at maturity will depend on market conditions and our future performance, which is subject to economic, financial, competitive and other factors beyond our control. If we are unable to make cash payments upon conversion of the 1.00% Notes and/or the 1.625% Notes, we would be required to issue significant amounts of our common stock, which would dilute existing stockholders. In addition, if we do not have sufficient cash to repurchase the 1.00% Notes and/or the 1.625% Notes following a fundamental change, we would be in default under the terms of such notes, which could cross default other debt and materially, adversely harm our business. The terms of the Amended Credit Agreement limit the amount of future indebtedness we may incur, but the terms of the 1.00% Notes and the 1.625% Notes do not limit the amount of future indebtedness we may incur. If we incur significantly more debt, this could intensify the risks described above. Our decision to use our cash for other purposes, such as to make acquisitions or to repurchase our common stock, could also intensify these risks.

The conditional conversion feature of the 1.00% Notes or the 1.625% Notes, if triggered, may adversely affect our financial condition and results of operations and, if we elect to settle the conversion of the 1.00% Notes or the 1.625% Notes in common stock, any such settlement could materially dilute the ownership interests of existing stockholders.

If specified conditions are met, holders of the 1.00% Notes may convert their notes prior to the close of business on the business day immediately preceding September 1, 2020 and holders of the 1.625% Notes may convert their notes prior to the close of business on the business day immediately preceding July 15, 2023. Unless we elect to satisfy our conversion obligations by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional shares), in the event the conditional conversion feature under either the 1.00% Notes or the 1.625% Notes is triggered, holders electing to convert their notes could require us to settle a portion or all of our conversion obligations through the payment of cash, which could materially adversely affect our liquidity. Alternatively, if the conditional conversion feature under either the 1.00% Notes or the 1.625% Notes is triggered, and holders do not elect to convert their notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of such notes as a current rather than long-term liability, which would result in a material reduction of our net working capital. Any material decrease in our liquidity or reduction in our net working capital could have a material adverse effect on our financial condition and results of operations. In addition, we may elect to settle a conversion of the 1.00% Notes or the 1.625% Notes solely in common stock to avoid an event of default under our Amended Credit Agreement, and

42

any such issuance of common stock could materially dilute the ownership interests of existing stockholders, including stockholders who previously converted such notes to shares of our common stock.

The fundamental change repurchase feature of our 1.00% Notes and 1.625% Notes may delay or prevent an otherwise beneficial attempt to take over our Company.

The terms of our 1.00% Notes and 1.625% Notes require us to repurchase such notes in the event of a fundamental change (as defined under the respective indentures governing such notes). In certain circumstances, a takeover of our Company could trigger an option of the holders of the 1.00% Notes and the 1.625% Notes to require us to repurchase such notes. This may have the effect of delaying or preventing a takeover of our Company that would otherwise be beneficial to investors in the 1.00% Notes and the 1.625% Notes and our common stock, which could materially decrease the value of such notes and of our common stock.

Note hedge and warrant transactions we have entered into may materially adversely affect the value of our common stock.

Concurrently with the issuance of the 1.00% Notes and the 1.625% Notes, we entered into note hedge transactions with certain financial institutions, which we refer to as the option counterparties. The convertible note hedges are expected to reduce the potential dilution upon any conversion of the respective series of notes and/or offset any cash payments we are required to make in excess of the principal amount of converted notes of such series, as the case may be. We also entered into warrant transactions with the option counterparties. However, the warrant transactions could separately have a dilutive effect on our common stock to the extent that the market price per share of our common stock exceeds $25.96, with respect to the 1.00% Notes, and $30.70, with respect to the 1.625% Notes.

In connection with establishing their initial hedge of the convertible note hedges and warrant transactions, the option counterparties or their respective affiliates have purchased shares of our common stock and/or entered into various derivative transactions with respect to our common stock following the pricing of the 1.00% Notes and the 1.625% Notes, respectively. The option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives contracts with respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market transactions prior to the maturity of the 1.00% Notes and the 1.625% Notes, respectively (and are likely to do so during any observation period related to a conversion of 1.00% Notes or 1.625% Notes following any repurchase of the 1.00% Notes or 1.625% Notes by us on any fundamental change repurchase date or otherwise). The potential effect, if any, of these transactions and activities on the market price of our common stock will depend in part on market conditions and cannot be ascertained at this time. Any of these activities could materially adversely affect the value of our common stock.

Counterparty risk with respect to the note hedge transactions, if realized, could have a material adverse impact on our results of operations.

The option counterparties are financial institutions or affiliates of financial institutions, and we are subject to the risk that these option counterparties may default under the note hedge transactions. We can provide no assurances as to the financial stability or viability of any of the option counterparties. Our exposure to the credit risk of the option counterparties is not secured by any collateral. If one or more of the option counterparties to one or more of our note hedge transactions becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at the time under those transactions.

43

To the extent the option counterparties do not honor their contractual commitments with us pursuant to the note hedge transactions, we could face a material increase in our exposure to potential dilution upon any conversion of the 1.00% Notes or the 1.625% Notes and/or cash payments we are required to make in excess of the principal amount of converted 1.00% Notes or 1.625% Notes, as the case may be. Our exposure will depend on many factors but, generally, the increase in our exposure will be correlated to the increase in the market price of our common stock and in the volatility of the market price of our common stock. In addition, upon a default by one of the option counterparties, we may suffer adverse tax consequences with respect to our common stock. Any such adverse tax consequences or increased cash payments could have a material adverse effect on our results of operations.

Trends, Risks and Uncertainties Relating to Our Common Stock

Fluctuations in our quarterly operating results may cause the market price of our common stock to decline.

Given the nature of the markets in which we participate, we cannot reliably predict future revenues and profitability, and unexpected changes may impact the value of our common stock. A large portion of our costs are fixed, due in part to our significant sales, research and development and manufacturing costs. Thus, small declines in revenues could negatively affect our operating results in any given quarter. In addition to the other factors described above, factors that could affect our quarterly operating results include:

• the timing and size of orders from our customers, including cancellations and reschedulings;

• the timing of introduction of new products;

• the gain or loss of significant customers, including as a result of industry consolidation or as a result of our acquisitions;

• seasonality in some of our target markets;

• changes in the mix of products we sell;

• changes in demand by theend-users of our customers’ products;

• market acceptance of our current and future products;

• variability of our customers’ product life cycles;

• availability of supplies and manufacturing services;

• changes in manufacturing yields or other factors affecting the cost of goods sold, such as the cost and availability of raw materials and the extent of utilization of manufacturing capacity;

• changes in the prices of our products, which can be affected by the level of our customers’ andend-users’ demand, technological change, product obsolescence, competition or other factors;

• cancellations, changes or delays of deliveries to us by our third-party manufacturers, including as a result of the availability of manufacturing capacity and the proposed terms of manufacturing arrangements;

• our liquidity and access to capital; and

• our research and development activities and the funding thereof.

An adverse change or development in any of the above factors could cause the market price of common stock to materially decline.

The market price of our common stock may be volatile, which could result in substantial losses for investors.

The stock markets in general, and the markets for high technology stocks in particular, have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock.

44

The market price of the common stock may also fluctuate significantly in response to the following factors, among others, some of which are beyond our control:

• variations in our quarterly operating results;

• the issuance or repurchase of shares of our common stock;

• changes in securities analysts’ estimates of our financial performance;

• changes in market valuations of similar companies;

• announcements by us or our competitors of significant contracts, acquisitions, strategic partnerships, joint ventures, capital commitments, new products or product enhancements;

• loss of a major customer or failure to complete significant transactions; and

• additions or departures of key personnel.

The trading price of our common stock in the past has had significant variance, and we cannot accurately predict every potential risk that may materially and adversely affect our stock price.

Provisions in our charter documents may delay or prevent the acquisition of our Company, which could materially adversely affect the value of our common stock.

Our certificate of incorporation andby-laws contain provisions that could make it harder for a third party to acquire us without the consent of our board of directors. These provisions:

• establish advance notice requirements for submitting nominations for election to the board of directors and for proposing matters that can be acted upon by stockholders at a meeting;

• authorize the issuance of “blank check” preferred stock, which is preferred stock that our board of directors can create and issue without prior stockholder approval and that could be issued with voting or other rights or preferences that could impede a takeover attempt; and

• require the approval by holders of at least 66 2/3% of our outstanding common stock to amend any of these provisions in our certificate of incorporation orby-laws.

Although we believe these provisions make a higher third-party bid more likely by requiring potential acquirers to negotiate with our board of directors, these provisions apply even if an initial offer may be considered beneficial by some stockholders. Any delay or prevention of an acquisition of our Company that would have been beneficial to our stockholders could materially decrease the value of our common stock.

Industry Overview

According to WSTS (an industry research firm), worldwide semiconductor industry sales were $412.2 billion in 2017, an increase of approximately 21.6% from $338.9 billion in 2016. We participate in unit and revenue surveys and use data summarized by WSTS to evaluate overall semiconductor market trends and also to track our progress against the market in the areas we provide semiconductor components. The following table sets forth total worldwide semiconductor industry revenues and revenues in our Serviceable Addressable Market (“SAM”) since 2013:

Year Ended December 31,	Worldwide Semiconductor Industry Sales (1)		Percentage Change		Serviceable Addressable Market Sales (1) (2)		Percentage Change
	(in billions)				(in billions)
2017	$	412.2		21.6 %	$	133.7		12.4 %
2016	$	338.9		1.1 %	$	118.9		2.6 %
2015	$	335.2		(0.2)%	$	115.9		(0.2)%
2014	$	335.8		9.9 %	$	116.1		11.3 %
2013	$	305.6		4.8 %	$	104.3		0.6 %

(1) Based on shipment information published by WSTS. We believe the data provided by WSTS is reliable, but we have not independently verified it. WSTS periodically revises its information. We assume no obligation to update such information.

(2) Our SAM comprises the following specific WSTS product categories: (a) discrete products (all discrete semiconductors other than sensors, microwave power transistors/modules, microwave diodes, microwave transistors, power modules, logic and optoelectronics); (b) standard analog products (amplifiers, VREGs and references, comparators, ASSP consumer, ASSP communications, ASSP computer, ASSP automotive and ASSP industrial and others); (c) standard logic products (general purpose logic); (d) standard product logic (consumer other, computer other peripherals, wired / wireless communications, automotive, industrial and multipurpose); (e) CMOS and CCD image sensors; (f) memory; (g) microcontrollers and (h) motor control modules. Our SAM is derived using the most recent information available, excluding foundry exposure, at the time of the filing of each respective period’s annual report and is revised in subsequent periods to reflect final results.

As indicated above, worldwide semiconductor sales increased from $305.6 billion in 2013 to $412.2 billion in 2017. The increase of 21.6% from 2016 to 2017 reflected improving macroeconomic conditions in the second half of 2017. Sales in our SAM increased from $104.3 billion in 2013 to $133.7 billion in 2017. The increase of 12.4% from 2016 to 2017 is consistent with the trend in the worldwide semiconductor market. The most recently published estimates of WSTS project a compound annual growth rate in our SAM of approximately 5.0% for the next three years. These projections are not ours and may not be indicative of actual results.

Historically, the semiconductor industry has been highly cyclical. During a down cycle, unit demand and pricing have tended to fall in tandem, resulting in revenue declines. In response to such declines, manufacturers have reduced or shut down production capacity. When new applications or other factors have caused demand to strengthen, production volumes have historically stabilized and then grown again. As market unit demand reaches levels above capacity production capabilities, shortages begin to occur, which typically causes pricing power to swing back from customers to manufacturers, thus prompting further capacity expansion. Such expansion has typically resulted in overcapacity following a decrease in demand, which has triggered another similar cycle.

ON Semiconductor Overview

We are driving innovation in energy-efficient electronics. Our extensive portfolio of sensors, power management, connectivity, custom and SoC, analog, logic, timing, and discrete devices helps customers efficiently solve their design challenges in advanced electronic systems and products. Our power management and motor driver semiconductor components control, convert, protect and monitor the supply of power to the different elements within a wide variety of electronic devices. Our custom ASICs and SOC devises use analog, MCU, DSP, mixed-signal and advanced logic capabilities to act as the brain behind many of our automotive, medical, aerospace/defense, consumer and industrial customers’ products. Our signal management semiconductor components provide high-performance clock management and data flow management for precision computing, communications and industrial systems. Our growing portfolio of sensors, including image sensors, optical image stabilization and auto focus devices provide advanced solutions for automotive, wireless, industrial and consumer applications. Our standard semiconductor components serve as “building blocks” within virtually all types of electronic devices. These various products fall into the logic, analog, discrete, image sensors and memory categories used by the WSTS group.

Our new product development efforts continue to be focused on building solutions in product areas that appeal to customers in focused market segments and across multiple high-growth applications. We collaborate with our customers to identify desired innovations in electronic systems in eachend-market that we serve. This enables us to participate in the fastest growing sectors of the market. We also innovate in advanced packaging technologies to support ongoing size reduction in electronic systems and in advanced thermal packaging to support high performance power conversion applications. It is our practice to regularlyre-evaluate our research and development spending, to assess the deployment of resources and to review the funding of high-growth technologies. We deploy people and capital with the goal of maximizing our investment in research and development in order to facilitate continued growth by targeting innovative products and solutions for high growth applications that position us to outperform the industry. Our design expertise in analog, digital, mixed signal and imaging ICs, combined with our extensive portfolio of standard products enable the company to offer comprehensive, value-added solutions to our global customers for their electronics systems.

We believe that some of the key factors and trends affecting our results of operations include, but not limited to:

• Our acquisition of Fairchild and our integration of Fairchild’s business into our operations;

• Macroeconomic conditions affecting the semiconductor industry;

• The cyclicality and seasonality of the semiconductor industry;

• The global economic climate;

• Our significant indebtedness, including the indebtedness incurred in connection with our acquisition of Fairchild;

• The impact of U.S. corporate tax reform and an uncertain corporate tax environment abroad;

• An uncertain political climate and related impacts on global trade;

• The effects of trends in the automotive and industrial end-markets on our revenues; and

• Competitive conditions, and in particular consolidation, within our industry.

Fairchild Acquisition

On September 19, 2016, we completed the Fairchild Transaction. The purchase price totaled $2,532.2 million and was funded by the borrowings against our Term Loan “B” Facility and a partial draw of our revolving Revolving Credit Facility and with cash on hand.

51

We believe that this acquisition has created a power semiconductor leader with strong capabilities in a rapidly consolidating semiconductor industry. The combination of Fairchild operations with our own has provided complementary product lines to offer customers the full spectrum of high, medium and low voltage products, and we will continue to pioneer technology and design innovation in efficient energy consumption to help our customers achieve success and drive value for our partners and employees around the world. The acquisition also expanded our footprint in wireless communication products, particularly in high efficiency power conversions and USB Type C communication and power delivery. See “Business - 2016 Acquisition Activity,” “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for additional information. See Note 4: “Acquisitions, Divestitures and Licensing Transactions” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K for additional information.

Recent ON Semiconductor Results

Our total revenues for the year ended December 31, 2017 were $5,543.1 million, an increase of approximately 41.9% from $3,906.9 million from the year ended December 31, 2016. The increase was primarily attributable to the acquisition of Fairchild. During 2017, we reported net income attributable to ON Semiconductor of $810.7 million compared to $182.1 million in 2016. The increase was attributable to the impact of the U.S. tax reform, as well as improved results and contributions from the acquired Fairchild business. Our gross margin increased by approximately 350 basis points to 36.7% in 2017 from 33.2% in 2016. The increase in gross margin was primarily due to higher factory utilization, product mix and contributions from the acquired Fairchild business.

ON Semiconductor Q1 2018 Outlook

Based upon product booking trends, backlog levels, and estimated turns levels, we estimate that our revenues will be approximately $1,340.0 to $1,390.0 million, gross margin as a percentage of revenues will be approximately 36.4% to 38.4%, operating expenses will be approximately $318.0 to $336.0 million, other income and expense (including interest expense), net will be approximately $33.0 to $36.0 million and diluted share count will be approximately 445.0 to 447.0 million in the first quarter of 2018.

Statements related to our outlook for the first quarter of 2018 are based on our current expectations, forecasts, estimates and assumptions. Such statements involve risks, uncertainties and other factors that could cause results or events to differ materially from those expressed in the forward-looking statements. See “Risk Factors” for additional information.

Business and Macroeconomic Environment Influence on Cost Savings and Restructuring Activities

In 2017 our initiatives were focused on synergy-related cost reductions from the Fairchild acquisition. Additionally, we have historically pursued, and expect to continue to pursue, other cost-saving initiatives to align our overall cost structure, capital investments and other expenditures with our expected revenue, spending and capacity levels based on our current sales and manufacturing projections. We have recognized efficiencies from previously implemented restructuring activities and programs and continue to implement profitability enhancement programs to improve our cost structure. The semiconductor industry has traditionally been highly cyclical and has often experienced significant downturns in connection with, or in anticipation of, declines in general economic conditions. We have historically taken significant actions to align our overall cost structure with our expectations of market conditions and by focusing on synergies-related cost reductions arising from each of our acquisitions. However, there can be no assurances that we will adequately forecast economic conditions or that we will effectively align our cost structure, capital investments and other expenditures with our revenue, spending and capacity levels in the future.

See “Results of Operations - Restructuring, asset impairments and other, net” below, along with Note 6: “Restructuring, Asset Impairments and Other, Net” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K for information relating to our most recent cost-saving initiatives.

Anticipated Impact of U.S. Tax Reform

On December 22, 2017, the U.S. enacted the Tax Act. The Tax Act reduces the U.S. federal corporate tax rate from 35% to 21%, requires companies to pay aone- time mandatory repatriation tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain future foreign earnings. Our income tax benefit for the year ended December 31, 2017 includes a provisional income tax benefit of $449.9 million as a result of the Tax Act. This benefit includes charges related to the mandatory repatriation tax and the remeasurement of deferred tax assets for the new, lower U.S. statutory rate of 21%, offset by a reduction of our deferred tax liability for undistributed current and prior years’ earnings of our foreign subsidiaries. Our provisional estimate of the mandatory repatriation tax is $219.4 million, which we believe can be offset, in part, by $191.1 million of existing U.S. tax credit carryforwards. After utilization of our tax credits, the remaining cash tax payable is expected to be $28.3 million, which would be payable over eight years with $2.3 million due in 2018.

We expect our future effective tax rate to more approximate the new U.S. federal statutory rate of 21%. The change in our future effective tax rate is not anticipated to have an effect on our cash tax until all of our U.S. federal net operating losses and credits have been utilized.

Results of Operations

Our results of operations for the year ended December 31, 2017 include the full year results of operations from our acquisition of Fairchild on September 19, 2016.

Revenues

Revenues were $5,543.1 million, $3,906.9 million and $3,495.8 million for 2017, 2016 and 2015, respectively. The increase of $1,636.2 million, or approximately 42%, in 2017 compared to 2016 was primarily attributable to approximately 65% and 32% increases in revenue in our Power Solutions Group and Analog Solutions Group, respectively, which included an entire twelve-month period of Fairchild revenues in 2017 and $155.1 million in revenues due to the change in revenue recognition on distributor sales during the first quarter of 2017.

54

The increase in revenues from 2016 compared to 2015 of $411.1 million, or approximately 12%, was primarily attributable to approximately 21% and 11% increases in revenue in our Power Solutions Group and Analog Solutions Group, respectively, which included Fairchild revenues of $411.5 million between September 19, 2016 and December 31, 2016. This increase was partially offset by lower revenues in our Image Sensor Group.

Revenues by reportable segment for each of 2017, 2016 and 2015 were as follows (dollars in millions):

	2017		As a % of   Revenue (1)		2016		As a % of   Revenue (1)		2015		As a % of     Revenue (1)

Total revenues	$	5,543.1			$	3,906.9			$	3,495.8

(1)   Certain of the amounts may not total due to rounding of individual amounts.

Revenues from the Power Solutions Group

Revenues from the Power Solutions Group increased by $1,110.7 million, or approximately 65%, during 2017 compared to 2016, and increased by $298.7 million, or approximately 21%, during 2016 compared to 2015.

The 2017 increase is primarily attributable to the acquisition of Fairchild, which had a full year contribution in 2017, as well as a $107.8 million impact due to the change in revenue recognition on distributor sales during the first quarter of 2017. These two factors contributed to increases in substantially all of the divisions within this segment, which resulted in a $417.8 million increase in revenues in our Power MOSFET division, a $327.8 million increase in revenues in our High Power division, and, to a lesser extent, $132.9 million increase in revenues in our Integrated Circuits division and $120.7 million increase in revenues in our Protection and Signal division.

The 2016 increase was primarily attributable to the acquisition of Fairchild, which had $277.5 million in revenue across various products within this segment. This was due to a $149.5 million increase in revenues in our Power MOSFET division, a $79.5 million increase in revenues in our High Power division, and to a lesser extent, a $47.7 million increase in revenues in our Integrated Circuits division and an $18.5 million increase in revenues in our Protection and Signal division.

Revenues from the Analog Solutions Group

Revenues from the Analog Solutions Group increased by $469.4 million, or approximately 32%, during 2017 compared to 2016 and increased by $142.9 million, or approximately 11%, during 2016 compared to 2015.

The 2017 increase is primarily attributable to the acquisition of Fairchild, which had a full year contribution in 2017, as well as a $42.1 million impact due to the change in revenue recognition on distributor sales during the first quarter of 2017. These two factors contributed to increases in substantially all of the divisions within this segment, which resulted in a $150.6 million increase in revenues in our Mobile Solutions division, a $100.3 million increase in revenues in our Automotive division, a $97.5 million increase in revenues in our Digital and DC/DC division and a $81.3 million increase in revenues in our Industrial and Offline Power division.

55

The 2016 increase was primarily attributable to the acquisition of Fairchild, which had $134.0 million in revenue across various products within this segment. This was due to a $72.7 million increase in revenues in our Mobile Solutions division, and to a lesser extent, $33.1 million increase in revenues in our Digital and DC/DC division and $29.8 million increase in revenues in our Automotive division.

Revenues from the Image Sensor Group

Revenues from the Image Sensor Group increased by $56.1 million, or approximately 8%, during 2017 compared to 2016 and decreased by $30.5 million, or approximately 4%, during 2016 compared to 2015.

The 2017 increase is primarily attributable to a $84.9 million, or 29% increase in revenues in our Automotive Solutions division, which was partially offset by a $39.6 million, or approximately 13% decrease in revenues in our Consumer Solutions division as a result of the exit of the Mobile CIS business which occurred during the fourth quarter of 2016. For further information on the Mobile CIS business exit see Note 4: “Acquisitions, Divestitures and Licensing Transactions”.

The 2016 decrease was primarily attributable to a $100.1 million, or 24% decrease in revenues in our Consumer Solutions division due to the exit of the Mobile CIS business, offset by a $57.7 million, or 24% increase in revenues in our Automotive Solutions division, and a $11.8 million, or 12% increase in revenues in our Industrial Solutions division.

Unallocated manufacturing (1)		(44.6	)		(0.8)%		(94.9	)		(2.4)%		(15.8	)		(0.5)%
Total gross profit	$	2,033.8			36.7 %	$	1,296.9			33.2 %		1,193.2			34.1 %

(1)   Unallocated manufacturing costs are being shown as a percentage of total revenue (includes expensing of the fair market valuestep-up of inventory of $67.5 million during 2016 and $13.6 million during 2017).

(2)   Certain of the amounts may not total due to rounding of individual amounts.

Our gross profit was $2,033.8 million, $1,296.9 million and $1,193.2 million for 2017, 2016 and 2015, respectively. The gross profit increase of $736.9 million, or approximately 57%, for 2017 compared to 2016 was primarily due to an increase in gross profit in our Power Solutions Group and Analog Solutions group, which included a full-year of contributions from the acquired Fairchild business. ISG gross profit improvement of $65.5 million was due to increased revenue in higher margin automotive and industrial markets offsetting decreased revenue on the exit of the Mobile CIS business.

The gross profit increase of $103.7 million, or approximately 9%, for 2016 compared to 2015 was primarily due to the contributions from Fairchild, which generated approximately $87.0 million of gross profit for 2016.

Gross margin increased to approximately 36.7% during 2017 compared to approximately 33.2% during 2016. Excluding the expensing of the fair market value of inventory step-up from the Fairchild acquisition, gross margin increased to approximately 36.9% during 2017 compared to approximately 34.9% during 2016. The increase was primarily due to higher factory utilization, product mix, which included the mix shift in imaging products to higher margin automotive and industrial imaging products, and the exit of the lower margin Mobile CIS business.

Gross margin decreased to approximately 33.2% during 2016 compared to approximately 34.1% during 2015. Excluding the expensing of the fair market value of inventorystep-up from the Fairchild acquisition of $67.5 million, gross margin increased to 34.9%, primarily due to higher factory utilization and product mix, which included the growth in ISG of higher margin automotive and industrial imaging products and the exit of the lower margin Mobile CIS business.

Operating Expenses

Research and Development

Research and development expenses were $594.4 million, $452.3 million and $396.7 million, representing approximately 11%, 12% and 11% of revenues, for 2017, 2016 and 2015, respectively.

57

The increase in research and development expenses of $142.1 million, or approximately 31%, during 2017 compared to 2016 was primarily associated with the acquisition of Fairchild, which added several categories of research and development expenses. Research and development expenses unrelated to Fairchild increased primarily in the area of payroll, including incentive compensation and payroll related costs as well as an overall increase in variable compensation for the combined company.

The increase in research and development expenses of $55.6 million, or approximately 14%, during 2016 compared to 2015 was primarily associated with the acquisition of Fairchild, which added to several categories of research and development expenses totaling $28.8 million. Research and development expenses unrelated to the Fairchild Transaction increased by $26.8 million, primarily in the area of payroll, including incentive compensation and payroll related costs, pension losses and IP related activities.

Selling and Marketing

Selling and marketing expenses were $315.9 million, $238.0 million and $204.3 million, representing approximately 6% of revenues in each year period, for 2017, 2016 and 2015, respectively.

The increase in selling and marketing expenses of $77.9 million, or approximately 33%, during 2017 compared to 2016 was primarily associated with the acquisition of Fairchild, primarily in the area of payroll, including incentive compensation and payroll related costs as well as an overall increase in variable compensation for the combined company. There were also increases in expenses related to commissions and advertising.

The increase in selling and marketing expenses of $33.7 million, or approximately 16%, during 2016 compared to 2015 was primarily associated with the acquisition of Fairchild, which had selling and marketing expenses of $26.7 million, primarily in the area of payroll, including incentive compensation and payroll-related costs. There were also increases in expenses related to outside services and travel.

General and Administrative

General and administrative expenses were $284.9 million, $230.3 million and $182.3 million, representing approximately 5%, 6% and 5% of revenues, for 2017, 2016 and 2015, respectively.

The increase in general and administrative expenses of $54.6 million, or approximately 24%, during 2017 compared to 2016 was primarily associated with the acquisition of Fairchild, primarily in the area of payroll, including incentive compensation and payroll related costs, as well as an overall increase in variable compensation for the combined company.

The increase in general and administrative expenses of $48.0 million, or approximately 26%, during 2016 compared to 2015 was primarily associated with the acquisition of Fairchild, which had general and administrative expenses of $36.9 million, primarily in the area of payroll, including incentive compensation and payroll related costs, outside services, travel related expenses, as well as acquisition related expenses.

Amortization of Acquisition—Related Intangible Assets

Amortization of acquisition-related intangible assets was $123.8 million, $104.8 million and $135.7 million for 2017, 2016 and 2015, respectively. The increase of $19.0 million during 2017 compared to 2016 was primarily associated with the amortization of our intangible assets acquired from the Fairchild acquisition, partially offset by the declining amortization of our Aptina intangible assets.

58

The decrease in amortization of acquisition-related intangible assets during 2016 compared to 2015 was attributable to the declining amortization of our Aptina and Truesense intangible assets, partially offset by the amortization of our intangible assets acquired from the Fairchild acquisition.

See Note 4: “Acquisitions, Divestitures and Licensing Transactions” and Note 5: “Goodwill and Intangible Assets” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K for additional information with respect to intangible assets.

Restructuring, asset impairments and other, net

Restructuring, asset impairments and other, net was $20.8 million, $33.2 million and $9.3 million for 2017, 2016 and 2015, respectively. The information below summarizes the major activities in each year.

2017

During 2017, we recorded approximately $20.8 million of net charges related to our restructuring programs, consisting primarily of $9.7 million of post-Fairchild acquisition restructuring costs, $2.2 million of the former System Solutions Group voluntary workforce reduction program costs, $7.3 million of asset impairment charges primarily for assetsheld-for-sale and $3.7 million of other costs, partially offset by a reversal of $2.1 million relating to manufacturing relocation program costs.

2016

During 2016, we recorded approximately $33.2 million of net charges related to our restructuring programs, consisting primarily of $25.7 million of post-Fairchild acquisition restructuring costs, $5.3 million of the former System Solutions Group segment voluntary workforce reduction program costs, and $2.1 million of manufacturing relocation program costs.

2015

During 2015, we recorded approximately $9.3 million of net charges related to our restructuring programs, consisting primarily of $3.5 million of employee separation charges from our European marketing organization relocation plan and $4.8 million of general workforce reductions, partially offset by a $3.4 million gain from the sale of assets.

For additional information, see Note 6: “Restructuring, Asset Impairments and Other, Net” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K.

Intangible Asset Impairment

2017

During 2017, we recorded $13.1 million of intangible asset impairment charges consisting of $7.7 million of charges relating to abandoned IPRD projects and $5.4 million relating to the impairment in the value of certain IPRD projects as a result of the annual impairment test performed during the fourth quarter of 2017.

59

2016

During 2016, we canceled certain of our previously capitalized IPRD projects and recorded intangible asset impairment charges of $2.2 million.

2015

During 2015, we canceled certain of our previously capitalized IPRD projects and recorded intangible asset impairment charges of $3.8 million.

See Note 5: “Goodwill and Intangible Assets” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K for additional information.

Other Income and Expenses

Interest Expense

Interest expense decreased by $4.1 million, or approximately 2.8%, to $141.2 million during 2017 compared to $145.3 million in 2016, primarily due to the interest rate reduction under our Amended Credit Agreement. Interest expense increased by $95.6 million, or approximately 192%, to $145.3 million during 2016, up from $49.7 million in 2015, primarily due to the substantial indebtedness incurred in order to acquire Fairchild. We expect interest expense to remain substantial in future periods as we service the debt we incurred in connection with the Fairchild Transaction. We recorded amortization of debt discount to interest expense of $30.8 million, $26.0 million and $17.5 million for 2017, 2016 and 2015, respectively. Our average gross amount of long-term debt balance (including current maturities) during 2017, 2016 and 2015 was $3,490.9 million, $2,661.3 million and $1,361.6 million, respectively. Our weighted average interest rate on our gross amount of long-term debt (including current maturities) was approximately 4.0%, 5.5% and 3.7% per annum in 2017, 2016 and 2015, respectively. See “Liquidity and Capital Resources - Key Financing and Capital Events” below and Note 8: “Long-Term Debt” in the notes to our audited consolidated financial statements included elsewhere in thisForm 10-K for a description of the indebtedness incurred for the Fairchild Transaction and our refinancing activities.

Gain on Divestiture of Business

Gain on divestiture of business was $12.5 million, $92.2 million and zero for 2017, 2016 and 2015, respectively. The information below summarizes the major activities in each year.

2017

Gain on divestiture of business was $12.5 million during 2017. On September 29, 2017, we sold Xsens Holding B.V. to mCube Hong Kong Limited (“mCube”) for cash consideration of $26.0 million and recorded a gain of $12.5 million after writing off the carrying value of the assets and liabilities sold of $7.0 million and goodwill of $6.5 million.

2016

Gain on divestiture of business was $92.2 million during 2016. On August 29, 2016, we sold two lines of business for $104.0 million to Littelfuse, Inc., (“Littelfuse”). In connection with the sale, we recorded a gain of $92.2 million after, among other things, transferring inventory of $4.1 million to Littelfuse, writing off goodwill of $3.4 million, and deferring $4.3 million of the proceeds to be recognized in the future.

60

For additional information, see Note 4: “Acquisitions, Divestitures and Licensing Transactions” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K.

Loss on Debt Refinancing and Prepayment

2017

Loss on debt refinancing and prepayment increased by $40.9 million from $6.3 million in 2016 to $47.2 million to 2017. The loss relates to the: (1) expensing of $26.2 million of unamortized debt discount and issuance costs attributed to the partial pay down of $575.0 million and the repricing of the Term Loan “B” Facility for the Second Amendment (as defined below); (2) expensing of $6.7 million of unamortized debt discount costs attributed to the partial pay down of $200.0 million of Term Loan “B” Facility; and (3) expensing of $14.3 million of unamortized debt discount and unamortized issuance costs attributed to the partial pay down of $400.0 million and the repricing of Term Loan “B” Facility for the Third Amendment to the Amended Credit Agreement (the “Third Amendment”). See Note 8: “Long-Term Debt” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K.

2016

Loss on debt refinancing and prepayment increased by $5.9 million from $0.4 million in 2015 to $6.3 million in 2016, due to the execution of the First Amendment (as defined below), which resulted in a debt extinguishment charge of $4.7 million, and the termination and replacement of our senior revolving credit facility by the Revolving Credit Facility, which resulted in a debt modification andwrite-off of $1.6 million in unamortized debt issuance costs.

2015

During 2015, we amended our senior revolving credit facility to, among other things, increase the borrowing capacity to $1.0 billion and reset the facility’s five year maturity. As a result of the amendment, wewrote-off $0.4 million of existing debt issuance costs associated with the facility.

Other (expense) income

Other income decreased by $7.5 million, from expense of $0.6 million in 2016 to $8.1 million in 2017. Other income decreased by $8.3 million, from income of $7.7 million in 2015 to an expense of $0.6 million in 2016. The change from year to year is attributable to fluctuations in foreign currencies against the U.S. dollar for the periods presented, net of the impact from our hedging activity and an adjustment to contingent consideration.

Licensing Income

Licensing income was $47.6 million for 2017 compared to zero for 2016. Approximately $45.1 million was attributable to payments received under an asset purchase agreement with HSET Electronic Tech (Hong Kong) Limited in connection with our licensing of certain patents related to the Mobile CIS business. The remaining $2.5 million was received from various other licensing agreements. See Note 4: “Acquisitions, Divestitures and Licensing Transactions” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K.

61

Income Tax (Provision) Benefit

We recorded an income tax benefit of $265.5 million, an income tax benefit of $3.9 million and an income tax provision of $10.8 million in 2017, 2016 and 2015, respectively.

This income tax benefit for the year ended December 31, 2017 consisted primarily of the provisional benefit of $449.9 million related to the estimated impact of U.S. tax reform and related effects and a discrete benefit of $13.2 million relating to equity award excess tax benefits. These benefits are offset by $186.8 million for income and withholding taxes of certain of our foreign and domestic current year operations and $10.8 million relating to the establishment of additional valuation allowance on certain foreign deferred tax assets.

The income tax benefit for 2016 consisted primarily of the reversal of $359.8 million of our previously established valuation allowance against part of our U.S. federal and foreign deferred tax assets and the release of $1.9 million for reserves and interest for uncertain tax positions in foreign taxing jurisdictions which were effectively settled or for which the statute lapsed during 2016. This was partially offset by $310.8 million related to the reversal of the prior years’ indefinite reinvestment assertion, $43.5 million for income and withholding taxes of certain of our foreign and domestic operations and $3.5 million of new reserves and interest on existing reserves for uncertain tax positions in foreign taxing jurisdictions.

The income tax provision for 2015 consisted of the reversal of $12.1 million of our previously established valuation allowance against our foreign deferred tax assets, the release of $4.3 million for reserves and interest for uncertain tax positions in foreign taxing jurisdictions that were effectively settled or for which the statute lapsed during 2015, and a change in tax rate that favorably impacted deferred balances by $1.6 million. This is partially offset by $24.4 million for income and withholding taxes of certain of our foreign and domestic operations and $4.4 million of new reserves and interest on existing reserves for uncertain tax positions in foreign taxing jurisdictions.

Our effective tax rate for 2017 was a benefit of 48.5%, which differs fromthe U.S. federal statutory income tax rate of 35% primarilydue to U.S. tax reform codified under the Tax Act. Our effective tax rate for 2016 was a benefit of 2.2%, which differs fromthe U.S. federal statutory income tax rate of 35% primarilydue to the release of our U.S. and Japan valuation allowances, partially offset by the reversal of the prior years’ indefinite reinvestment assertion. Our effective tax rate for 2015 was a provision of 4.9%, which differs from the U.S. federal statutory income tax rate of 35% primarily due to our change in valuation allowance, deemed dividend income from foreign subsidiaries and tax rate differential in our foreign subsidiaries.

We expect our future effective tax rate to more approximate the new U.S. federal statutory rate of 21%. The change in our future effective tax rate is not anticipated to have an effect on our cash tax until all of our U.S. federal net operating losses and credits have been utilized.

We continue to maintain a valuation allowance on a portion of our tax credits in foreign jurisdictions and foreign net operating losses, a substantial portion of which relate to Japan net operating losses which are projected to expire prior to utilization. In addition, we also maintain a full valuation allowance on our U.S. state deferred tax assets.

For additional information, see Note 15: “Income Taxes” in the notes to the audited consolidated financial statements included elsewhere in this Form10-K.

Liquidity and Capital Resources

This section includes a discussion and analysis of our cash requirements,off-balance sheet arrangements, contingencies, sources and uses of cash, operations, working capital and long-term assets and liabilities.

Contractual Obligations

Our principal outstanding contractual obligations relate to our long-term debt, capital leases, operating leases and purchase obligations. The following table summarizes our contractual obligations at December 31, 2017 and the effect such obligations are expected to have on our liquidity and cash flow in the future (in millions):

	Payments Due by Period
Contractual obligations (1)	Total		2018		2019		2020		2021		2022		Thereafter
Long-term debt, excluding capital leases (2)	$	3,532.9	$	325.0	$	121.8	$	770.3	$	463.0	$	52.8	$	1,800.0

Total contractual obligations	$	4,241.1	$	779.0	$	206.6	$	814.3	$	501.6	$	76.1	$	1,863.5

(1) The table above excludes approximately $16.6 million of liabilities related to unrecognized tax benefits because we are unable to reasonably estimate the timing of the settlement of such liabilities.

(2) Includes interest payments at applicable rates as of December 31, 2017.

(3) These represent ouroff-balance sheet arrangements (See “Liquidity and CapitalResources—Off-Balance Sheet Arrangements” for a description of ouroff-balance sheet arrangements).

The table also excludes our pension obligations. We expect to make cash contributions to comply with local funding requirements and required benefit payments of approximately $16.4 million in 2018. This future payment estimate assumes we continue to meet our statutory funding requirements. The timing and amount of contributions may be impacted by a number of factors, including the funded status of the plans. Beyond 2018, the actual amounts required to be contributed are dependent upon, among other things, interest rates, underlying asset returns and the impact of legislative or regulatory actions related to pension funding obligations. See Note 11: “Employee Benefit Plans” in the notes to our audited consolidated financial statements included elsewhere in thisForm 10-K for more information on our pension obligations.

Our balance of cash and cash equivalents was $949.2 million as of December 31, 2017. We believe that our cash flows from operations, coupled with our existing cash and cash equivalents, will be adequate to fund our operating and capital needs for at least the next 12 months. Total cash and cash equivalents at December 31, 2017 include approximately $422.4 million available in the United States. We require a substantial amount of cash in the United States for operating requirements, debt service, debt repayments and acquisitions. While we hold a significant amount of cash, cash equivalents and short-term investments outside the United States in various foreign subsidiaries, we have the ability to obtain cash in the United States through distributions from our foreign subsidiaries in order to cover our domestic needs, by utilizing existing credit facilities, or through new bank loans or debt obligations.

See Note 8: “Long-Term Debt,” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K for a discussion of our long-term debt. See “Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities” included elsewhere in this Form10-K for a discussion of restrictions on our ability to pay dividends and our stock repurchase activities.

Off-Balance Sheet Arrangements

In the ordinary course of business, we enter into various operating leases for buildings and equipment including our mainframe computer system, desktop computers, communications, foundry equipment and service agreements relating to this equipment.

In the ordinary course of business, we provide standby letters of credit or other guarantee instruments to certain parties initiated by either our subsidiaries or us, as required for transactions including, but not limited to: material purchase commitments, agreements to mitigate collection risk, leases, utilities or customs guarantees. Our Revolving Credit Facility includes $15.0 million of availability for the issuance of letters of credit. There were $0.4 million letters of credit outstanding under our Revolving Credit Facility as of December 31, 2017, which reduces our borrowing capacity. We also had outstanding guarantees and letters of credit outside of our Revolving Credit Facility of $5.7 million at December 31, 2017.

As part of securing financing in the ordinary course of business, we issued guarantees related to certain of our capital lease obligations, equipment financing, lines of credit and real estate mortgages, which totaled $120.6 million as of December 31, 2017. We are also a guarantor of SCI LLC’snon-collateralized loan with SMBC, which had a balance of $122.7 million as of December 31, 2017, and which was fully repaid on January 2, 2018. See Note 8: “Long-Term Debt” and Note 12: “Commitments and Contingencies” in the notes to our audited consolidated financial statements found elsewhere in this Form10-K for additional information.

Based on historical experience and information currently available, we believe that we will not be required to make payments under the standby letters of credit or guarantee arrangements for the foreseeable future.

For our operating leases, we expect to make cash payments and similarly incur expenses totaling $160.5 million as payments come due. We have not recorded any liability in connection with these operating leases, letters of credit and guarantee arrangements. See Note 12: “Commitments and Contingencies” in the notes to our audited consolidated financial statements found elsewhere in this Form10-K for additional information.

Contingencies

We are a party to a variety of agreements entered into in the ordinary course of business pursuant to which we may be obligated to indemnify other parties for certain liabilities that arise out of or relate to the subject matter of the agreements. Some of the agreements entered into by us require us to indemnify the other party against losses due to IP infringement, property damage including environmental contamination, personal injury, failure to comply with applicable laws, our negligence or willful misconduct, or breach of representations and warranties and covenants related to such matters as title to sold assets.

We face risk of exposure to warranty and product liability claims in the event that our products fail to perform as expected or such failure of our products results, or is alleged to result, in economic damage, bodily injury or property damage. In addition, if any of our designed products are alleged to be defective, we may be required to participate in their recall. Depending on the significance of any particular customer and other relevant factors, we may agree to provide more favorable rights to such customer for valid defective product claims.

64

We maintain directors’ and officers’ insurance policies that indemnify our directors and officers against various liabilities, including certain liabilities under the Exchange Act, that might be incurred by any director or officer in his or her capacity as such.

The Fairchild Agreement provides for indemnification and insurance rights in favor of Fairchild’s then current and former directors, officers and employees. Specifically, the Company has agreed that, for no fewer than six years following the Fairchild acquisition, the Company will: (a) indemnify and hold harmless each such indemnitee against losses and expenses (including advancement of attorneys’ fees and expenses) in connection with any proceeding asserted against the indemnified party in connection with such person’s servings as a director, officer, employee or other fiduciary of Fairchild or its subsidiaries prior to the effective time of the acquisition; (b) maintain in effect all provisions of the certificate of incorporation or bylaws of Fairchild or any of its subsidiaries or any other agreements of Fairchild or any of its subsidiaries with any indemnified party regarding elimination of liability, indemnification of officers, directors and employees and advancement of expenses in existence on the date of the Fairchild Agreement for acts or omissions occurring prior to the effective time of the acquisition and; (c) subject to certain qualifications, provide to Fairchild’s then current directors and officers an insurance and indemnification policy that provides coverage for events occurring prior to the effective time of the acquisition that is no less favorable than Fairchild’s then-existing policy, or, if insurance coverage that is no less favorable is unavailable, the best available coverage.

While our future obligations under certain agreements may contain limitations on liability for indemnification, other agreements do not contain such limitations and under such agreements it is not possible to predict the maximum potential amount of future payments due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by us under any of these indemnities have not had a material effect on our business, financial condition, results of operations or cash flows, and we do not believe that any amounts that we may be required to pay under these indemnities in the future will be material to our business, financial condition, results of operations or cash flows.

See “Legal Proceedings” and Note 12: “Commitments and Contingencies” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K for possible contingencies related to legal matters. See also “Business—Government Regulation” for information on certain environmental matters.

Sources and Uses of Cash

We require cash to fund our operating expenses and working capital requirements, including outlays for strategic acquisitions and investments, research and development, to make capital expenditures, to repurchase our common stock and other Company securities, and to pay debt service, including principal and interest and capital lease payments. Our principal sources of liquidity are cash on hand, cash generated from operations and funds from external borrowings and equity issuances. In the near term, we expect to fund our primary cash requirements through cash generated from operations and cash and cash equivalents on hand. We also have the ability to utilize our Revolving Credit Facility.

As part of our business strategy, we review acquisition and divestiture opportunities and proposals on a regular basis. See Note 4: “Acquisitions, Divestitures and Licensing Transactions” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K for additional information.

We believe that the key factors that could affect our internal and external sources of cash include:

• Factors that affect our results of operations and cash flows, including the impact on our business and operations as a result of changes in demand for our products, competitive pricing

65

pressures, effective management of our manufacturing capacity, our ability to achieve further reductions in operating expenses, the impact of our restructuring programs on our production and cost efficiency and our ability to make the research and development expenditures required to remain competitive in our business; and

• Factors that affect our access to bank financing and the debt and equity capital markets that could impair our ability to obtain needed financing on acceptable terms or to respond to business opportunities and developments as they arise, including interest rate fluctuations, macroeconomic conditions, sudden reductions in the general availability of lending from banks or the related increase in cost to obtain bank financing, and our ability to maintain compliance with covenants under our debt agreements in effect from time to time.

Our ability to service our long-term debt, including our 1.625% Notes, 1.00% Notes, Revolving Credit Facility and Term Loan “B” Facility, to remain in compliance with the various covenants contained in our debt agreements and to fund working capital, capital expenditures and business development efforts will depend on our ability to generate cash from operating activities, which is subject to, among other things, our future operating performance, as well as to general economic, financial, competitive, legislative, regulatory and other conditions, some of which may be beyond our control.

If we fail to generate sufficient cash from operations, we may need to raise additional equity or borrow additional funds to achieve our longer term objectives. There can be no assurance that such equity or borrowings will be available or, if available, will be at rates or prices acceptable to us. We believe that cash flow from operating activities coupled with existing cash and cash equivalents, short-term investments and existing credit facilities will be adequate to fund our operating and capital needs, as well as enable us to maintain compliance with our various debt agreements, through at least the next 12 months. To the extent that results or events differ from our financial projections or business plans, our liquidity may be adversely impacted.

During the ordinary course of business, we evaluate our cash requirements and, if necessary, adjust our expenditures for inventory, operating expenditures and capital expenditures to reflect the current market conditions and our projected sales and demand. Our capital expenditures are primarily directed toward production equipment and capacity expansion. Our capital expenditure levels can materially influence our available cash for other initiatives. During 2017, we paid $387.5 million for capital expenditures, while in 2016 we paid $210.7 million. Capital expenditure levels can materially influence our available cash for other initiatives. Our capital expenditures have historically been approximately 6% to 7% of annual revenues and we expect to continue to incur capital expenditures to support our business activities. Future capital expenditures may be impacted by events and transactions that are not currently forecasted.

On November 30, 2017, we, certain of our domestic subsidiaries (the “Guarantors”), the several lenders party thereto and the Agent entered into the Third Amendment. The Third Amendment provides for, among other things, modifications to the Amended Credit Agreement to reduce the interest rate payable under the Term Loan “B” Facility and to increase the amount that may be borrowed pursuant to the Revolving Credit Facility to $1.0 billion. In connection with the Third Amendment, the Company prepaid $400.0 million of borrowings under the Term Loan “B” Facility, bringing the outstanding borrowings under the Term Loan “B” Facility to approximately $1.2 billion as of the date of the Third Amendment. We had $400 million of borrowings outstanding under the Revolving Credit Facility as of the date of the Third Amendment.

On March 31, 2017, we and the Guarantors entered into the Second Amendment (the “Second Amendment”) to the Amended Credit Agreement. The Second Amendment provides for, among other things, modifications to the

66

Amended Credit Agreement to allow the Notes to rank pari passu with borrowings under the Amended Credit Agreement and to reduce the interest rates payable under the Term Loan “B” Facility and the Revolving Credit Facility.

On March 31, 2017, we completed the private unregistered offering of $575.0 million aggregate principal amount of the 1.625% Notes, which amount includes the full exercise of the initial purchasers’ option to purchase additional 1.625% Notes. The net proceeds from the offering of the 1.625% Notes were used to repay $562.1 million of borrowings outstanding under the Term Loan “B” Facility.

On April 15, 2016, we entered into two new financing arrangements to secure funds for the purchase consideration of Fairchild among certain other items, including a $2.2 billion Term Loan “B” Facility, with the proceeds deposited into escrow accounts and used to finance the transaction, which occurred on September 19, 2016. On September 30, 2016, we amended the financing arrangements and increased the Term Loan “B” Facility by $200.0 million. The associated interest expense related to our Term Loan “B” Facility has had, and will continue to have, a material impact on our results of operations throughout the term of the Amended Credit Agreement.

During the year ended December 31, 2015, we issued $690.0 million of our 1.00% Notes and used a portion of the proceeds to pay down amounts previously drawn on our senior revolving credit facility. We also increased the borrowing capacity of our senior revolving credit facility from $800.0 million to $1.0 billion and reset the five-year maturity. See Note 8: “Long-Term Debt” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K for additional information.

Cash Management

Our ability to manage cash is limited, as our primary cash inflows and outflows are dictated by the terms of our sales and supply agreements, contractual obligations, debt instruments and legal and regulatory requirements. While we have some flexibility with respect to the timing of capital equipment purchases, we must invest in capital equipment on a timely basis to allow us to maintain our manufacturing efficiency and support our platforms of new products.

Primary Cash Flow Sources

Our long-term cash generation is dependent on the ability of our operations to generate cash. Our cash flows from operating activities were $1,094.2 million, $581.2 million, and $470.6 million for the years ended December 31, 2017, 2016 and 2015, respectively.

Our cash flows provided by operating activities for the year ended December 31, 2017, which includes a full year of Fairchild, increased by approximately $513.0 million, or approximately 88.3%, compared to the year ended December 31, 2016. The increase was primarily attributable to better results of operations. Our ability to maintain positive operating cash flows is dependent on, among other factors, our success in achieving our revenue goals and manufacturing and operating cost targets.

Our management of our assets and liabilities, including both working capital and long-term assets and liabilities, also influences our operating cash flows, and each of these components is discussed below.

67

Working Capital

Working capital, calculated as total current assets less total current liabilities, fluctuates depending onend-market demand and our effective management of certain items such as receivables, inventory and payables. In times of escalating demand, our working capital requirements may be affected as we purchase additional manufacturing materials and increase production. Our working capital may also be affected by restructuring programs, which may require us to use cash for severance payments, asset transfers and contract termination costs. In addition, our working capital may be affected by acquisitions and transactions involving our convertible notes and other debt instruments. Our working capital, excluding cash and cash equivalents and short-term investments, was $575.1 million as of December 31, 2017 and has fluctuated between $338.1 million and $668.2 million at the end of each of our last six fiscal quarters. Our working capital, including cash and cash equivalents and short-term investments, was $1,524.3 million as of December 31, 2017 and has fluctuated between $1,304.5 million and $1,524.3 million at the end of each of our last six fiscal quarters.

Although investments made to fund working capital will reduce our cash balances, these investments are necessary to support business and operating initiatives. For the year ended December 31, 2017, our working capital was most significantly impacted by our capital expenditures and our repayment of long-term debt, including capital leases. See Note 8: “Long-Term Debt” and Note 9: “Earnings Per Share and Equity” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K for additional information.

Long-Term Assets and Liabilities

Our long-term assets consist primarily of property, plant and equipment, intangible assets, deferred taxes and goodwill.

Our manufacturing rationalization plans have included efforts to utilize our existing manufacturing assets and supply arrangements more efficiently. We believe that near-term access to additional manufacturing capacity, should it be required, could be readily obtained on reasonable terms through manufacturing agreements with third parties. We will continue to look for opportunities to make strategic purchases in the future for additional capacity.

Our long-term liabilities, excluding long-term debt and deferred taxes, consist of liabilities under our foreign defined benefit pension plans and contingent tax reserves. In regard to our foreign defined benefit pension plans, generally, our annual funding of these obligations is equal to the minimum amount legally required in each jurisdiction in which the plans operate. This annual amount is dependent upon numerous actuarial assumptions. For additional information, see Note 11: “Employee Benefit Plans” and Note 15: “Income Taxes” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K.

Key Financing and Capital Events

Overview

For the past several years, we have undertaken various measures to secure liquidity to pursue acquisitions, repurchase shares of our common stock, reduce interest costs, amend existing key financing arrangements and, in some cases, extend a portion of our debt maturities to continue to provide us additional operating flexibility. Certain of these measures continued in 2017. Set forth below is a summary of certain key financing events

68

affecting our capital structure during the last three years. For further discussion of our debt instruments, see Note 8: “Long-Term Debt” and for further discussion on share repurchase program, see Note 9: “Earnings Per Share and Equity” in the notes to our audited consolidated financial statements included elsewhere in thisForm 10-K.

Recent Events

2017 Financing Events

Amendments to the Credit Agreement

On April 15, 2016, we entered into the Amended Credit Agreement. On March 31, 2017, we entered into the Second Amendment to the Amended Credit Agreement. The Second Amendment provided for, among other things, modifications to the Amended Credit Agreement to allow the 1.625% Notes to rank pari passu with borrowings under the Amended Credit Agreement and to reduce the interest rates payable under the Term Loan “B” Facility and the Revolving Credit Facility. For any interest period ending after the date of the Second Amendment, the Second Amendment reduced the applicable margins on borrowings under the Amended Credit Agreement incurred as eurocurrency loans (“Eurocurrency Loans”) to 1.75% and 2.25% for borrowings under the Revolving Credit Facility and the Term Loan “B” Facility, respectively, and reduced applicable margins on borrowings under the Amended Credit Agreement incurred as alternate base rate loans (“ABR Loans”) to 0.75% and 1.25% for borrowings under the Revolving Credit Facility and the Term Loan “B” Facility, respectively. For further discussion of the Amended Credit Agreement, see “2016 Financing Events—Amended Credit Agreement.”

During the quarter ended June 30, 2017, we repaid in full the $120.0 million outstanding under the Revolving Credit Facility. During the quarter ended September 29, 2017, we prepaid $200.0 million of borrowings under the Term Loan “B” Facility.

On November 30, 2017, we entered into the Third Amendment to the Amended Credit Agreement. The Third Amendment provided for, among other things, modifications to the Amended Credit Agreement to reduce the interest rate payable under the Term Loan “B” Facility and to increase the amount that may be borrowed pursuant to the Revolving Credit Facility to $1.0 billion. For any interest period ending after the date of the Third Amendment, the Third Amendment reduced the applicable margins on Eurocurrency Loans to 2.00% for borrowings under the Term Loan “B” Facility, and reduced applicable margins on ABR Loans to 1.00% for borrowings under the Term Loan “B” Facility. In connection with the Third Amendment, we prepaid $400.0 million of borrowings under the Term Loan “B” Facility, bringing the outstanding borrowings under the Term Loan “B” Facility to approximately $1.2 billion as of the date of the Third Amendment. We had $400.0 million of borrowings outstanding under the Revolving Credit Facility as of the date of the Third Amendment.

Issuance of 1.625% Notes

On March 31, 2017, we completed a private placement of $575.0 million of our 1.625% Notes to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The 1.625% Notes are governed by an indenture (the “1.625% Indenture”) between the Company, the guarantors party thereto, and Wells Fargo Bank, National Association, as trustee. The net proceeds from the offering of the 1.625% Notes were used to repay $562.1 million of borrowings outstanding under the Term Loan “B” Facility. The 1.625% Notes bear interest at the rate of 1.625% per year from the date of issuance, payable semiannually in arrears on April 15 and

69

October 15 of each year, beginning on October 15, 2017. The 1.625% Notes are fully and unconditionally guaranteed, on a joint and several basis, by each of our subsidiaries that is a borrower or guarantor under our Amended Credit Agreement.

Share Repurchase Program

We repurchased approximately 1.6 million shares of our common stock for an aggregate purchase price of $25.0 million in connection with the offering of the 1.625% Notes during the year ended December 31, 2017.

2016 Financing Events

Redemption of 2.625% Notes, Series B

On November 17, 2016, we announced that we would be exercising our option to redeem the entire $356.9 million outstanding principal amount of the 2.625% Notes, Series B, on December 20, 2016 pursuant to the terms of the indenture governing the 2.625% Notes, Series B (the “2.625% Notes, Series B Indenture”). The holders of the 2.625% Notes, Series B, had the right to convert their 2.625% Notes, Series B, into shares of common stock of the Company at a conversion rate of 95.2381 shares per $1,000 principal amount until the close of business on December 19, 2016. We satisfied our conversion obligation with respect to the 2.625% Notes, Series B, tendered for conversion with cash. The final conversion was settled on January 26, 2017, resulting in an aggregate payment of approximately $445.0 million for the redemption and conversion of the 2.625% Notes, Series B.

Amended Credit Agreement

On April 15, 2016, we entered into: (1) the Amended Credit Agreement; and (2) a Guarantee and Collateral Agreement (the “Guarantee and Collateral Agreement”) with the Guarantors, pursuant to which the Amended Credit Agreement are guaranteed by the Guarantors and secured by a pledge of substantially all of the assets of the Company and the Guarantors, including a pledge of the equity interests in certain of the Company’s domestic and first-tier foreign subsidiaries, subject to customary exceptions. The obligations under the Amended Credit Agreement are also secured by mortgages on certain real property assets of the Company and its domestic subsidiaries. Subject to the terms and conditions of the Amended Credit Agreement, on April 15, 2016, we borrowed an aggregate of $2.2 billion under the Term Loan “B” Facility (the “Gross Proceeds”).

On April 15, 2016, the Gross Proceeds, along with certain other amounts funded by the Company, were deposited into escrow accounts pursuant to the terms of an escrow agreement and, upon release from escrow, in accordance with the terms of the escrow agreement, were available primarily to pay, directly or indirectly, the purchase price of the Fairchild Transaction pursuant to the terms of the Fairchild Agreement and certain other items, subject to the terms and conditions of the Amended Credit Agreement.

On September 19, 2016, the Company completed the acquisition and acquired 100% of Fairchild, whereby Fairchild became a wholly-owned subsidiary of the Company. The Company funded the acquisition with the Term Loan “B” Facility proceeds and Company funded amounts previously deposited into escrow accounts, proceeds from a $200.0 million draw against the Company’s Revolving Credit Facility, and existing cash on hand. Proceeds from the Term Loan “B” Facility were also used to pay for debt issuance costs, transaction fees and expenses.

On September 30, 2016, the Company entered into the First Amendment to the Amended Credit Agreement. The First Amendment reduced the applicable margins on Eurocurrency Loans to 2.75% and 3.25% for borrowings

70

under the Revolving Credit Facility and the Term Loan “B” Facility, respectively, and reduced applicable margins on ABR Loans to 1.75% and 2.25% for borrowings under the Revolving Credit Facility and the Term Loan “B” Facility, respectively. Additionally, the First Amendment included the following: (i) the Term Loan “B” Facility was increased to $2.4 billion; (ii) certain restructuring transactions and intercompany intellectual property transfers are permitted in order to achieve efficient integration of the Company, its subsidiaries and acquired entities; and (iii) certain changes were made to the provisions regarding hedge agreements to allow the Company and each of the guarantors to enter into certain hedge arrangements. The Company used the additional $200.0 million proceeds under the Term Loan “B” Facility to pay off the Company’s $200.0 million outstanding balance under the Revolving Credit Facility.

Share Repurchase Program

We did not repurchase shares pursuant to our share repurchase program during the year ended December 31, 2016, as we focused on the funding required for the Fairchild Transaction.

2015 Financing Events

Issuance of 1.00% Notes

During the second quarter of 2015, we completed a private unregistered offering for an aggregate principal amount of $690.0 million of our 1.00% Notes. The 1.00% Notes mature on December 1, 2020, unless earlier purchased or converted. We concurrently entered into convertible note hedge and warrant transactions with certain institutional counterparties. A portion of the proceeds from the offering were used to finance the hedge and warrant transactions associated with the issuance of the 1.00% Notes, to pay down the senior revolving credit facility and to repurchase $70.0 million of our common stock. The issuance was a private placement made pursuant to Rule 144A under the Securities Act.

Amended Senior Revolving Credit Facility

During the second quarter of 2015, we amended our $800.0 million senior revolving credit facility to, among other things, increase the borrowing capacity to $1.0 billion and reset the five year maturity. We also amended the terms of the related Amended and Restated Credit Agreement. The facility includes $15.0 million of availability for the issuance of letters of credit, $15.0 million of availability for swingline loans for short-term borrowings and a foreign currency sublimit of $75.0 million. The facility may be used for general corporate purposes, including working capital, stock repurchase, and/or acquisitions.

Share Repurchase Program

During the year ended December 31, 2015, we purchased approximately 30.4 million shares of our common stock pursuant to our share repurchase program for an aggregate purchase price of approximately $347.8 million, exclusive of fees, commissions and other expenses, at a weighted-average execution price of $11.46 per share. See “Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities” for additional information.

Debt Guarantees and Related Covenants

As of December 31, 2017, we were in compliance with the indentures relating to our 1.00% Notes and 1.625% Notes and with covenants relating to our Term Loan “B” Facility, Revolving Credit Facility and our other debt

71

agreements. Our 1.00% Notes are senior to the existing and future subordinated indebtedness of ON Semiconductor and its guarantor subsidiaries. Our 1.625% Notes rank equally in right of payment to all of our existing and future senior debt and are subordinated to all of our existing and future secured debt. See Note 8: “Long-Term Debt” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K for additional information.

Critical Accounting Policies and Estimates

The accompanying discussion and analysis of our financial condition and results of operations is based upon our audited consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. We believe certain of our accounting policies are critical to understanding our financial position and results of operations. We utilize the following critical accounting policies in the preparation of our financial statements.

Use of Estimates.    The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. We evaluate these estimates and judgments on an ongoing basis and base our estimates on experience, current and expected future conditions, third-party evaluations and various other assumptions that we believe are reasonable under the circumstances. Significant estimates have been used by management in conjunction with the following: (i) estimates of future payouts for customer incentives and estimates of amounts subject to allowances, returns and warranties; (ii) measurement of valuation allowances relating to inventories and trade receivables; (iii) future cash flows used to assess and test for impairment of goodwill and indefinite-lived intangible assets and long-lived assets, if applicable; (iv) assumptions surrounding future pension obligations; (v) fair values of share-based compensation and of financial instruments (including derivative financial instruments); (vi) measurement of valuation allowances against deferred tax assets, evaluations of uncertain tax positions, and the impact of the U.S. tax reform; and (vii) estimates and assumptions used in connection with business combinations. Actual results may differ from these estimates.

Revenue.    We generate revenues from sales of our semiconductor products to OEMs, electronic manufacturing service providers and distributors. We also generate revenue, to a much lesser extent, from manufacturing and design services provided to customers. Revenue is recognized when persuasive evidence of an arrangement exists, title and risk of loss pass to the customer (generally upon shipment), the price is fixed or determinable and collectability is reasonably assured. Revenues are recorded net of provisions for related sales returns and allowances.

Prior to the first quarter of 2017, for products sold to distributors who are entitled to ship and credit rights, we recognized the related revenues and cost of revenues when we were informed by the distributor that it had resold the products to theend-user. This was due to our inability to reliably estimate up front the effects of the returns and allowances with these distributors for sales originating through the ON Semiconductor systems and processes. Legacy systems and processes of Fairchild enable us to estimate up front the effects of returns and allowances provided to these distributors and thereby record the net revenues at the time of sale related to a legacy Fairchild system and process. We acquired Fairchild on September 19, 2016.

When we adopt ASU2014-09, ASU2015-14, ASU2016-08, ASU2016-10, ASU2016-12 and ASU2016-20 (see Note 3: “Recent Accounting Pronouncements”), one of the more significant impacts would be that we would not be permitted to defer revenue until sale by the distributor to the end customer, but rather, would be required to estimate the effects of returns and allowances provided to certain distributors and record revenue at the time of

72

sale to the distributor. In anticipation of the adoption of the new standards, we had developed our internal systems, processes and controls for making the required estimates on the sales to these distributors. As a result of these process changes, during the first quarter of 2017, we were able to reliably estimate upfront the effects of returns and allowances and record revenues at the time of sales to these distributors. As a result of this change, we recognized $155.1 million in revenue during the first quarter of 2017. The impact of this change resulted in an increase of $59.0 million to income before income taxes, or $0.09 per basic and diluted share, for the year ended December 31, 2017. Additionally, we recorded accruals for the estimated returns from the distributors, which decreased revenues by $8.1 million and income before income taxes by $5.3 million for the year ended December 31, 2017.

Although payment terms vary, most distributor agreements require payment within 30 days. Sales returns and allowances are estimated based on historical experience. Our OEM customers do not have the right to return products, other than pursuant to the provisions of our standard warranty. Sales to distributors, however, are typically made pursuant to agreements that provide return rights with respect to discontinued or slow-moving products. Provisions for discounts and rebates to customers, estimated returns and allowances, and other adjustments are provided for in the same period the related revenues are recognized, and are netted against revenues. We review warranty and related claims activities and records provisions, as necessary.

Freight and handling costs are included in cost of revenues and are recognized as period expense when incurred. Taxes assessed by government authorities on revenue-producing transactions, including value-added and excise taxes, are presented on a net basis (excluded from revenues) in the statement of operations.

Inventories.    We carry our inventories at the lower of standard cost (which approximates actual cost on afirst-in,first-out basis) or net realizable value and record provisions for potential excess and obsolete inventories based upon a regular analysis of inventory on hand compared to historical and projectedend-user demand. These provisions can influence our results from operations. For example, when demand falls for a given part, all or a portion of the related inventory that is considered to be in excess of anticipated demand is reserved, impacting our cost of revenues and gross profit. If demand recovers and the parts previously reserved are sold, we will generally recognize a higher than normal margin. However, the majority of product inventory that has been previously reserved is ultimately discarded. Although we do sell some products that have previously been written down, such sales have historically been relatively consistent on a quarterly basis and the related impact on our margins has not been material.

Impairment of Long-Lived Assets.    We evaluate the recoverability of the carrying amount of our property, plant and equipment and intangible assets (excluding IPRD), whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be fully recoverable. Impairment is first assessed when the undiscounted expected cash flows derived for an asset group are less than its carrying amount. Impairment losses, if applicable, are measured as the amount by which the carrying value of an asset group exceeds its fair value and are recognized in operating results. We continually apply our best judgment when applying these impairment rules to determine the timing of the impairment test, the undiscounted cash flows used to assess impairments and the fair value of an impaired asset group. The dynamic economic environment in which we operate and the resulting assumptions used to estimate future cash flows impact the outcome of our impairment tests. In recent years, most of our asset groups that have been impaired consist of assets that were ultimately abandoned, sold or otherwise disposed of due to cost reduction activities and the consolidation of our manufacturing facilities. In some instances, these assets have subsequently been sold for amounts higher than their impaired value with related gains recorded in the restructuring, asset impairment and other, net line item in our consolidated statement of operations and disclosed in the footnotes to the financial statements.

73

IPRD.    We are required to test our IPRD assets for impairment annually using the guidance for indefinite-lived intangible assets. An IPRD asset is considered to be impaired when the asset’s carrying amount is greater than its fair value. Our impairment evaluation consists of first assessing qualitative factors to determine whether events and circumstances indicate that it is more likely than not that the IPRD asset is impaired. If it is more likely than not that the asset is impaired, we calculate the fair value of the IPRD asset and record an impairment charge if the carrying amount exceeds fair value. We determine the fair value based on an income approach, which is calculated as the present value of the estimated future cash flows of the IPRD asset. The assumptions about estimated cash flows include factors such as future revenues, gross profits, operating expenses, and industry trends. We can bypass the qualitative assessment for any asset in any period and proceed directly to the quantitative impairment test.

Goodwill.    We evaluate our goodwill for potential impairment annually during the fourth quarter and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Our divisions, which are components of our operating segments, constitute reporting units for purposes of allocating and testing goodwill. Our divisions are one level below the operating segments, constituting individual businesses, at which level our segment management conducts regular reviews of the operating results. Our impairment evaluation of goodwill consists of a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit exceeds its carrying amount. If this qualitative assessment indicates it is more likely than not the estimated fair value of a reporting unit exceeds its carrying value, no further analysis is required and goodwill is not impaired. Otherwise, we perform a quantitative goodwill impairment test to determine if goodwill is impaired. The quantitative test compares the fair value of a reporting unit with its carrying amount, including goodwill.

If the fair value of the reporting unit exceeds the carrying value of the net assets associated with that unit, goodwill is not considered impaired. If the carrying value of the net assets associated with the reporting unit exceeds the fair value of the reporting unit, goodwill is considered impaired and will be determined as the amount by which the reporting units carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Determining the fair value of our reporting units is subjective in nature and involves the use of significant estimates and assumptions, including projected net cash flows, discount and long-term growth rates. We determine the fair value of our reporting units based on an income approach, whereby the fair value of the reporting unit is derived from the present value of estimated future cash flows. The assumptions about estimated cash flows include factors such as future revenues, gross profits, operating expenses, and industry trends. We consider historical rates and current market conditions when determining the discount and long-term growth rates to use in its analysis. We consider other valuation methods, such as the cost approach or market approach, if it is determined that these methods provide a more representative approximation of fair value. Changes in these estimates based on evolving economic conditions or business strategies could result in material impairment charges in future periods. We base our fair value estimates on assumptions we believe to be reasonable. Actual results may differ from those estimates.

Our next annual test for impairment is expected to be performed on the first day of the fourth quarter of 2018; however, identification of a triggering event may result in the need for earlier reassessments of the recoverability of our goodwill and may result in material impairment charges in future periods.

Defined Benefit Pension Plans and Related Benefits.    We maintain defined benefit pension plans covering certain of ournon-U.S. employees. For financial reporting purposes, net periodic pension costs and pension obligations are determined based upon a number of actuarial assumptions, including discount rates for plan obligations, assumed rates of return on pension plan assets and assumed rates of compensation increase for employees participating in the plans. These assumptions are based upon management’s judgment and

74

consultation with actuaries, considering all known trends and uncertainties. Actual results that differ from these assumptions impact the expense recognition and cash funding requirements of our pension plans. As of December 31, 2017, a 20 basis point change in the discount rates utilized to determine our continuing foreign pension liabilities and expenses would have impacted our results by approximately $8.3 million.

Contingencies.    We are involved in a variety of legal matters that arise in the normal course of business. Based on the available information, we evaluate the relevant range and likelihood of potential outcomes and we record the appropriate liability when the amount is deemed probable and reasonably estimable.

Income Taxes.    Income taxes are accounted for using the asset and liability method. Under this method, deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for those deferred tax assets for which we cannot conclude that it is more likely than not that such deferred tax assets will be realized.

In determining the amount of the valuation allowance, estimated future taxable income, as well as feasible tax planning strategies for each taxing jurisdiction, are considered. If we determine it is more likely than not that all or a portion of the remaining deferred tax assets will not be realized, the valuation allowance will be increased with a charge to income tax expense. Conversely, if we determine it is more likely than not to be able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been provided, the related portion of the valuation allowance will be recorded as a reduction to income tax expense.

We recognize and measure benefits for uncertain tax positions using atwo-step approach. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining if the weight of available evidence indicates that is it more likely than not that the tax positions will be sustained upon audit, including resolution of any related appeals or litigation processes. For tax positions that are more likely than not to be sustained upon audit, the second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon settlement. Our practice is to recognize interest and/or penalties related to income tax matters in income tax expense. Significant judgment is required to evaluate uncertain tax positions. Evaluations are based upon a number of factors, including changes in facts or circumstances, changes in tax law, correspondence with tax authorities during the course of tax audits and effective settlement of audit issues. Changes in the recognition or measurement of uncertain tax positions could result in material increases or decreases in income tax expense in the period in which the change is made, which could have a material impact to our effective tax rate. See Note 15: “Income Taxes” in the notes to our audited consolidated financial statements included elsewhere in this Form10-K for additional information. See also “Management’s Discussion and Analysis - Results of Operations - Income Tax Provision (Benefit)” for additional information.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

We are exposed to financial market risks, including changes in interest rates and foreign currency exchange rates. To mitigate these risks, we utilize derivative financial instruments. We do not use derivative financial instruments for speculative or trading purposes.

As of December 31, 2017, our long-term debt (including current maturities) totaled $3,175.0 million. We have no interest rate exposure to rate changes on our fixed rate debt, which totaled $2,053.5 million (excluding the SMBC note of $122.7 million which was paid on January 2, 2018). We do have interest rate exposure with respect to the $998.8 million balance of our variable interest rate debt outstanding as of December 31, 2017. A 50 basis point increase in interest rates would impact our expected annual interest expense for the next 12 months by approximately $5.0 million. However, some of this impact would be offset by additional interest earned on our cash and cash equivalents should rates on deposits and investments also increase. We entered into interest rate swaps to hedge some of the risk of variability in cash flows resulting from future interest payments on our variable interest rate debt under the Term Loan “B” Facility.

To ensure the adequacy and effectiveness of our foreign exchange hedge positions, we continually monitor our foreign exchange forward positions, both on a stand-alone basis and in conjunction with their underlying foreign currency exposures, from an accounting and economic perspective. However, given the inherent limitations of forecasting and the anticipatory nature of exposures intended to be hedged, we cannot provide any assurances that such programs will offset more than a portion of the adverse financial impact resulting from unfavorable movements in foreign exchange rates.

We are subject to risks associated with transactions that are denominated in currencies other than our functional currencies, as well as the effects of translating amounts denominated in a foreign currency to the United States Dollar as a normal part of the reporting process. Our Japanese operations utilize Japanese Yen as the functional currency, which results in a translation adjustment that is included as a component of accumulated other comprehensive income.

We enter into forward foreign currency contracts that economically hedge the gains and losses generated by there-measurement of certain recorded assets and liabilities in anon-functional currency. Changes in the fair value of these undesignated hedges are recognized in other income and expense immediately as an offset to the changes in the fair value of the assets or liabilities being hedged. The notional amount of foreign currency contracts at December 31, 2017 and 2016 was $130.5 million and $95.9 million, respectively. Our policies prohibit speculation on financial instruments, trading in currencies for which there are no underlying exposures, or entering into trades for any currency to intentionally increase the underlying exposure.

Substantially all of our revenue is transacted in U.S. dollars. However, a significant amount of our operating expenditures and capital purchases are transacted in local currencies, including Japanese Yen, Euros, Korean Won, Malaysian Ringgit, Philippines Peso, Singapore Dollars, Swiss Francs, Chinese Renminbi, and Czech Koruna. Due to the materiality of our transactions in these local currencies, our results are impacted by changes in currency exchange rates measured against the U.S. dollar. For example, we determined that based on a hypothetical weighted-average change of 10% in currency exchange rates, our results would have impacted our income before taxes by approximately $101.2 million for the year ended December 31, 2017, assuming no offsetting hedge positions.

See Note 14: “Financial Instruments” in the notes to the audited consolidated financial statements included elsewhere in this Form10-K for further information with respect to our hedging activity.

Item 9A.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures.

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules13a-15(e) and15d-15(e) of the Exchange Act). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered in this Form10-K, our disclosure controls and procedures were effective to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the required time periods and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting.

We also carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of changes to our internal control over financial reporting (as defined in Rules13a-15(f) and15d-15(f) of the Exchange Act) that occurred during the fiscal quarter ended December 31, 2017.

On September 19, 2016, we acquired Fairchild, which operated under its own set of systems and internal controls. Fairchild’s systems and control environment have been integrated into the Company’s systems and control environment as of October 30, 2017.

Other than as described above, there have been no other changes to our internal control over financial reporting (as defined in Exchange Act Rules13a-15(f) and15d-15(f)) that occurred during the fiscal quarter ended December 31, 2017 which have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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 Exchange Act Rules13a-15(f) and15d-15(f)). 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 and procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2017. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission inInternal Control -Integrated Framework 2013. Based on this assessment, management has concluded that our internal control over financial reporting was effective as of December 31, 2017.

The effectiveness of our internal control over financial reporting as of December 31, 2017 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears in “Exhibits and Financial Statement Schedules” of this Form10-K.

Report of Independent Registered Public Accounting Firm

Tothe Board of Directors and Stockholders of

ON Semiconductor Corporation

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of ON Semiconductor Corporation and its subsidiariesas of December 31, 2017 and 2016,and the related consolidated statements of operations and comprehensive income, of stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2017, including the related notes and schedule of valuation and qualifying accounts for each of the three years in the period ended December 31, 2017 appearing under Item 15(a)(2) (collectively referred to as the “consolidated financial statements”).We also have audited the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established inInternal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2017 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established inInternal Control—Integrated Framework (2013) issued by the COSO.

Change in Accounting Principle

As discussed in Note 3: “Recent Accounting Pronouncements” to the consolidated financial statements, the Company changed the manner in which it accounts for excess tax benefits from share-based compensation in 2017.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidatedfinancial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures

94

that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1:    Background and Basis of Presentation

ON Semiconductor Corporation (“ON Semiconductor”), together with its wholly and majority-owned subsidiaries (the “Company”), prepares its consolidated financial statements in accordance with generally accepted accounting principles in the United States of America. As of December 31, 2017, the Company was organized into three operating segments, which also represent its three reporting segments: Power Solutions Group,Analog Solutions Group and Image Sensor Group. Additional information about the Company’s operating and reporting segments is included in Note 18: “Segment Information”.

All dollar amounts in tabular presentations are in millions, except per share amounts and unless otherwise noted.

Note 2:    Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the assets, liabilities, revenues and expenses of all wholly-owned and majority-owned subsidiaries over which the Company exercises control and, when applicable, entities in which the Company has a controlling financial interest or is the primary beneficiary. Investments in nonconsolidated affiliates that represent less than 20% of the related ownership interests and where the Company does not have the ability to exert significant influence are accounted for as cost method investments. All material intercompany balances and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Management evaluates these estimates and judgments on an ongoing basis and base its estimates on experience, current and expected future conditions, third-party evaluations and various other assumptions that management believes are reasonable under the circumstances. Significant estimates have been used by management in conjunction with the following: (i) estimates of future payouts for customer incentives and estimates of amounts subject to allowances, returns and warranties; (ii) measurement of valuation allowances relating to inventories and trade receivables; (iii) future cash flows used to assess and test for impairment of goodwill and indefinite-lived intangible assets and long-lived assets, if applicable; (iv) assumptions surrounding future pension obligations; (v) fair values of share-based compensation and of financial instruments (including derivative financial instruments); (vi) measurement of valuation allowances against deferred tax assets, evaluations of uncertain tax positions, and the impact of the U.S. tax reform; and (vii) estimates and assumptions used in connection with business combinations. Actual results may differ from the estimates and assumptions used in the consolidated financial statements and related notes.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity to the Company of three months or less to be cash equivalents. Cash and cash equivalents are maintained with reputable major financial

100

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

institutions. If, due to current economic conditions, one or more of the financial institutions with which the Company maintains deposits fails, the Company’s cash and cash equivalents may be at risk. Deposits with these banks generally exceed the amount of insurance provided on such deposits; however, these deposits typically may be redeemed upon demand and, as a result of the quality of the respective financial institutions, management believes these deposits bear minimal risk.

Short-Term Investments

Short-term investments includeheld-to-maturity securities andavailable-for-sale securities.Held-to-maturity securities have an original maturity to the Company between three months and one year and are carried at amortized cost as it is the intent of the Company to hold these securities until maturity.Available-for-sale securities are stated at fair value and the net unrealized gains or losses onavailable-for-sale securities are recorded as a component of accumulated other comprehensive loss or income, net of income taxes.

Allowance for Doubtful Accounts

In the ordinary course of business, the Company providesnon-collateralized credit terms to its customers. Accordingly, the Company maintains an allowance for doubtful accounts for probable losses on uncollectible accounts receivable. The Company routinely analyzes accounts receivable and considers history, customer creditworthiness, facts and circumstances specific to outstanding balances, current economic trends and payment term changes when evaluating the adequacy of the allowance for doubtful accounts.

Inventories

Inventories are stated at the lower of standard cost (which approximates actual cost on afirst-in,first-out basis) or net realizable value. General market conditions, as well as the Company’s design activities, can cause certain of its products to become obsolete. The Company writes down excess and obsolete inventories based upon a regular analysis of inventory on hand compared to historical and projectedend-user demand. These write downs can influence results from operations. For example, when demand for a given part falls, all or a portion of the related inventory that is considered to be in excess of anticipated demand is written down, impacting cost of revenues and gross profit. If demand recovers and the parts previously written down are sold, a higher than normal margin will generally be recognized. However, the majority of product inventory that has been previously written down is ultimately discarded. Although the Company does sell some products that have previously been written down, such sales have historically been consistently immaterial and the related impact on the Company’s gross profit has also been immaterial.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost and are depreciated over estimated useful lives of30-50 years for buildings and3-20 years for machinery and equipment using straight-line methods. Expenditures for maintenance and repairs are charged to operations in the period in which the expense is incurred. When assets are retired or otherwise disposed of, the related costs and accumulated depreciation are removed from the balance sheet and any resulting gain or loss is reflected in operations in the period realized.

101

ON SEMICONDUCTOR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

The Company evaluates the recoverability of the carrying amount of its property, plant and equipment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be fully recoverable. A potential impairment charge is evaluated when the undiscounted expected cash flows derived from an asset group are less than its carrying amount. Impairment losses, if applicable, are measured as the amount by which the carrying value of an asset group exceeds its fair value and are recognized in operating results. Judgment is used when applying these impairment rules to determine the timing of the impairment test, the undiscounted cash flows used to assess impairments and the fair value of the asset group.

Business Combination Purchase Price Allocation

The allocation of the purchase price of business combinations is based on management estimates and assumptions, which utilize established valuation techniques appropriate for the high-technology industry. These techniques include the income approach, cost approach or market approach, depending upon which approach is the most appropriate based on the nature and reliability of available data. The income approach is predicated upon the value of the future cash flows that an asset is expected to generate over its economic life. The cost approach takes into account the cost to replace (or reproduce) the asset and the effects on the asset’s value of physical, functional and/or economic obsolescence that has occurred with respect to the asset. The market approach is used to estimate value from an analysis of actual transactions or offerings for economically comparable assets available as of the valuation date.

Goodwill

Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in the Company’s acquisitions.

The Company evaluates its goodwill for potential impairment annually during the fourth quarter and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. The Company’s divisions, which are components of its operating segments, constitute reporting units for purposes of allocating and testing goodwill. The Company’s divisions are one level below the operating segments, constituting individual businesses, at which level the Company’s segment management conducts regular reviews of the operating results. The Company’s impairment evaluation of goodwill consists of a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit exceeds its carrying amount. If this qualitative assessment indicates it is more likely than not the estimated fair value of a reporting unit exceeds its carrying value, no further analysis is required and goodwill is not impaired. Otherwise, the Company performs a quantitative goodwill impairment test to determine if goodwill is impaired. The quantitative test compares the fair value of a reporting unit with its carrying amount, including goodwill.

If the fair value of the reporting unit exceeds the carrying value of the net assets associated with that unit, goodwill is not considered impaired. If the carrying value of the net assets associated with the reporting unit exceeds the fair value of the reporting unit, goodwill is considered impaired and will be determined as the amount by which the reporting units carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Determining the fair value of the Company’s reporting units is subjective in nature and involves the use of significant estimates and assumptions, including projected net cash flows, discount and long-term growth rates. The Company determines the fair value of its reporting units based on an income approach, whereby the fair value of the reporting unit is derived from the present value of estimated future cash flows. The assumptions

102

ON SEMICONDUCTOR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

about estimated cash flows include factors such as future revenues, gross profits, operating expenses and industry trends. The Company considers historical rates and current market conditions when determining the discount and long-term growth rates to use in its analysis. The Company considers other valuation methods, such as the cost approach or market approach, if it is determined that these methods provide a more representative approximation of fair value. Changes in these estimates based on evolving economic conditions or business strategies could result in material impairment charges in future periods. The Company bases its fair value estimates on assumptions it believes to be reasonable. Actual results may differ from those estimates.

Intangible Assets

The Company’s acquisitions have resulted in intangible assets consisting of values assigned to customer relationships, patents, developed technology, IPRD and trademarks. IPRD is considered an indefinite-lived intangible asset until the abandonment or completion of the associated research and development efforts. If abandoned, the assets would be impaired. If the activities are completed, a determination is made regarding the useful lives of such assets and methods of amortization.

The Company is required to test its IPRD assets for impairment annually using the guidance for indefinite-lived intangible assets. An IPRD asset is considered to be impaired when the asset’s carrying amount is greater than its fair value. The Company’s impairment evaluation consists of first assessing qualitative factors to determine whether events and circumstances indicate that it is more likely than not that the IPRD asset is impaired. If it is more likely than not that the asset is impaired, the Company calculates the fair value of the IPRD asset and records an impairment charge if the carrying amount exceeds fair value. The Company determines the fair value based on an income approach, which is calculated as the present value of the estimated future cash flows of the IPRD asset. The assumptions about estimated cash flows include factors such as future revenues, gross profits, operating expenses and industry trends. The Company can bypass the qualitative assessment for any asset in any period and proceed directly to the quantitative impairment test.

The remaining intangible assets are stated at cost less accumulated amortization, are amortized over their estimated useful lives, and are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of an asset group containing these assets may not be recoverable. A potential impairment charge is evaluated when the undiscounted expected cash flows derived from an asset group are less than its carrying amount. Impairment losses are measured as the amount by which the carrying value of an asset group exceeds its fair value and are recognized in operating results. Judgment is used when applying these impairment rules to determine the timing of the impairment test, the undiscounted cash flows used to assess impairments and the fair value of an asset group. The dynamic economic environment in which the Company operates and the resulting assumptions used to estimate future cash flows impact the outcome of these impairment tests.

Treasury Stock

Treasury stock is recorded at cost, inclusive of fees, commissions and other expenses, when outstanding common shares are repurchased by the Company, including when outstanding shares are withheld to satisfy tax withholding obligations in connection with certain shares pursuant to RSUs under the Company’s share-based compensation plans.

103

ON SEMICONDUCTOR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

Debt Issuance Costs

Debt issuance costs forline-of-credit agreements, including the Company’s Revolving Credit Facility, are capitalized and amortized over the term of the underlying agreements on a straight-line basis. Amortization of these debt issuance costs is included in interest expense while the unamortized balance is included in other assets.

Debt issuance costs for the Company’s convertible notes are recorded as a direct deduction from the carrying amount of the convertible notes, consistent with debt discounts, and are amortized over the term of the convertible notes using the effective interest method. Amortization of these debt issuance costs is included in interest expense.

Revenue Recognition

The Company generates revenues from sales of its semiconductor products to OEMs, electronic manufacturing service providers and distributors. The Company also generates revenue, to a much lesser extent, from manufacturing and design services provided to customers. Revenue is recognized when persuasive evidence of an arrangement exists, title and risk of loss pass to the customer (generally upon shipment), the price is fixed or determinable and collectability is reasonably assured. Revenues are recorded net of provisions for related sales returns and allowances.

Prior to the first quarter of 2017, for products sold to distributors who are entitled to ship and credit rights, the Company recognized the related revenues and cost of revenues when it was informed by the distributor that it had resold the products to theend-user. This was due to the Company’s inability to reliably estimate up front the effects of the returns and allowances with these distributors for sales originating through the ON Semiconductor systems and processes. Legacy systems and processes of Fairchild enable the Company to estimate up front the effects of returns and allowances provided to these distributors and thereby record the net revenues at the time of sale related to a legacy Fairchild system and process. The Company acquired Fairchild on September 19, 2016.

When the Company adopts ASU2014-09, ASU2015-14, ASU2016-08, ASU2016-10, ASU2016-12 and ASU2016-20 (see Note 3: “Recent Accounting Pronouncements”), one of the more significant impacts would be that it would not have been permitted to defer revenue until sale by the distributor to the end customer, but rather, would be required to estimate the effects of returns and allowances provided to certain distributors and record revenue at the time of sale to the distributor. In anticipation of the adoption of the new standards, the Company had developed its internal systems, processes and controls for making the required estimates on the sales to these distributors. As a result of these process changes, during the first quarter of 2017, the Company was able to reliably estimate upfront the effects of returns and allowances and record revenues at the time of sales to these distributors. As a result of this change, the Company recognized $155.1 million in revenue during the first quarter of 2017. The impact of this change resulted in an increase of $59.0 million to income before income taxes, or $0.09 per basic and diluted share, for the year ended December 31, 2017. Additionally, the Company recorded accruals for the estimated returns from the distributors, which decreased revenues by $8.1 million and income before income taxes by $5.3 million for the year ended December 31, 2017.

Although payment terms vary, most distributor agreements require payment within 30 days. Sales returns and allowances are estimated based on historical experience. The Company’s OEM customers do not have the right to return products other than pursuant to the provisions of the Company’s standard warranty. Sales to

104

ON SEMICONDUCTOR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

distributors, however, are typically made pursuant to agreements that provide return rights with respect to discontinued or slow-moving products. Provisions for discounts and rebates to customers, estimated returns and allowances, and other adjustments are provided for in the same period the related revenues are recognized, and are netted against revenues. The Company reviews warranty and related claims activities and records provisions, as necessary.

Freight and handling costs are included in cost of revenues and are recognized as period expense when incurred. Taxes assessed by government authorities on revenue-producing transactions, including value-added and excise taxes, are presented on a net basis (excluded from revenues) in the statement of operations.

Warranty Reserves and Discounts

The Company generally warrants that products sold to its customers will, at the time of shipment, be free from defects in workmanship and materials and conform to specifications. The Company’s standard warranty extends for a period of two years from the date of delivery, except in the case of Image Sensor products, which are warrantied for one year from the date of delivery. At the time revenue is recognized, the Company establishes an accrual for estimated warranty expenses associated with its sales, recorded as a component of cost of revenues. In addition, the Company also offers cash discounts to certain customers for payments received within an agreed upon time, generally ten days after shipment. The Company records a reserve for cash discounts as a reduction to accounts receivable and a reduction to revenues based on experience with each customer.

Research and Development Costs

Research and development costs are expensed as incurred.

Share-Based Compensation

Share-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized as expense over the employee’s requisite service period. The Company has outstanding awards with performance, time and service-based vesting provisions.

Income Taxes

Income taxes are accounted for using the asset and liability method. Under this method, deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for those deferred tax assets for which management cannot conclude that it is more likely than not that such deferred tax assets will be realized.

In determining the amount of the valuation allowance, estimated future taxable income, as well as feasible tax planning strategies for each taxing jurisdiction are considered. If the Company determines it is more likely than not that all or a portion of the remaining deferred tax assets will not be realized, the valuation allowance will be

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

increased with a charge to income tax expense. Conversely, if the Company determines it is more likely than not to be able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been provided, the related portion of the valuation allowance will be recorded as a reduction to income tax expense.

The Company recognizes and measures benefits for uncertain tax positions using atwo-step approach. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining if the weight of available evidence indicates that is it more likely than not that the tax positions will be sustained upon audit, including resolution of any related appeals or litigation processes. For tax positions that are more likely than not to be sustained upon audit, the second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon settlement. The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. Significant judgment is required to evaluate uncertain tax positions. Evaluations are based upon a number of factors, including changes in facts or circumstances, changes in tax law, correspondence with tax authorities during the course of tax audits and effective settlement of audit issues. Changes in the recognition or measurement of uncertain tax positions could result in material increases or decreases in income tax expense in the period in which the change is made, which could have a material impact to the Company’s effective tax rate.

Foreign Currencies

Most of the Company’s foreign subsidiaries conduct business primarily in U.S. dollars and, as a result, utilize the dollar as their functional currency. For the remeasurement of financial statements of these subsidiaries, assets and liabilities in foreign currencies that are receivable or payable in cash are remeasured at current exchange rates, while inventories and othernon-monetary assets in foreign currencies are remeasured at historical rates. Gains and losses resulting from the remeasurement of such financial statements are included in the operating results, as are gains and losses incurred on foreign currency transactions.

The majority of the Company’s Japanese subsidiaries utilize Japanese Yen as their functional currency. The assets and liabilities of these subsidiaries are translated at current exchange rates, while revenues and expenses are translated at the average rates in effect for the period. The related translation gains and losses are included in other comprehensive income or loss within the Consolidated Statements of Operations and Comprehensive Income. Due to the changing profile of the operations of these subsidiaries, fromtime-to-time, the Company evaluates the economic indicators from a long-term perspective to determine if a change in functional currencies would be appropriate.

Defined Benefit Pension Plans

The Company maintains defined benefit pension plans covering certain of its foreign employees. For financial reporting purposes, net periodic pension costs and pension obligations are determined based upon a number of actuarial assumptions, including discount rates for plan obligations, assumed rates of return on pension plan assets and assumed rates of compensation increases for employees participating in plans. These assumptions are based upon management’s judgment and consultation with actuaries, considering all known trends and uncertainties.

Contingencies

The Company is involved in a variety of legal matters, intellectual property matters, environmental, financing and indemnification contingencies that arise in the ordinary course of business. Based on the information available, management evaluates the relevant range and likelihood of potential outcomes and records the appropriate liability when the amount is deemed probable and reasonably estimable.

Fair Value Measurement

The Company measures certain of its financial andnon-financial assets at fair value by using a fair value hierarchy that prioritizes certain inputs into individual fair value measurement approaches. Fair value is the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, as follows:

• Level 1 - Quoted prices in active markets for identical assets or liabilities;

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

• Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Companies may choose to measure certain financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value option has been elected must be reported in earnings. The Company has elected not to carry any of its debt instruments at fair value.

Note 3:    Recent Accounting Pronouncements

ASUs Adopted:

ASU No2017-04 - Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (‘ASU2017-04’)

In January 2017, the FASB issued ASU2017-04, which simplifies the accounting for goodwill impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. The amendment is effective for calendaryear-end SEC filers in 2020, and early adoption is permitted. The Company early adopted ASU2017-04 during the first quarter of 2017. The adoption of this standard did not impact the Company’s financial statements.

ASU No.2016-09 - Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (‘ASU2016-09’)

In March 2016, the FASB issued ASU2016-09, which is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. The amendments are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption was permitted. ASU2016-09, which the Company adopted as of the first quarter of 2017, requires that excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) be recognized as income tax expense or benefit in the income statement. The tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. Excess tax benefits should be recognized regardless of whether the benefit reduces taxes payable in the current period. Previously, the Company followed the guidance that the tax benefit and credit to additional paid in capital for a windfall tax benefit should not be recorded until the deduction reduces income taxes payable. The Company has been historically in a net taxable loss. Therefore, the windfall tax benefit has not reduced income taxes payable. The new guidance requires all excess tax benefits that were not previously recognized because the related tax deduction had not reduced current taxes payable to be recorded on a modified retrospective basis through a cumulative effect adjustment to retained earnings as of the beginning of the period in which the new guidance was adopted. The financial statement impact of this change resulted in $68.1 million being recorded as a credit to retained earnings as of January 1, 2017. On a prospective basis, the impact of windfalls and shortfalls will be recorded to income tax expense on a discrete basis.

The Company will continue to classify employee taxes paid on the statement of cash flows when ON Semiconductor withholds shares fortax-withholding purposes as a financing activity. The Company will continue to estimate forfeitures as part of share based compensation expense recognition.

ASU No.2015-11 - Inventory (Topic 330): Simplifying the Measurement of Inventory (‘ASU2015-11’)

In July 2015, the FASB issued ASU2015-11, which requires that an entity should measurein-scope inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The amendments are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption was permitted. The Company adopted ASU2015-11 during the first quarter of 2017. The adoption of this standard did not have a material impact on the financial statements.

ASUs Pending Adoption:

ASUNo. 2017-12 - Derivatives and Hedging (topic 815): Targeted Improvements to Accounting for Hedging Activities (‘ASU2017-12’)

In August 2017, the FASB issued ASUNo. 2017-12 to better align hedge accounting with risk management strategies, and as a result, more hedging strategies will be eligible for hedge accounting. Public business entities will have until the end of the first quarter in which a hedge is designated to perform an initial assessment of a hedge’s effectiveness. After initial qualification, the new guidance permits a qualitative effectiveness assessment for certain hedges instead of a quantitative test, if the Company can reasonably support an expectation of high

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

effectiveness throughout the term of the hedge. An initial quantitative test to establish that the hedge relationship is highly effective is still required. The amendments are effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of ASU2017-12 may have on its consolidated financial statements.

ASUNo. 2017-09 - Scope of Modification Accounting (‘ASU2017-09’)

In May 2017, the FASB issued ASUNo. 2017-09 to reduce diversity in practice and provide clarity regarding existing guidance in ASC 718, “Stock Compensation.” The amendments clarify that an entity should apply modification accounting in response to a change in the terms and conditions of an entity’s share-based payment awards unless three newly specified criteria are met. The amendments are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company does not anticipate the adoption of ASU2017-09 will have a material impact on its consolidated financial statements.

ASU No2017-07 - Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (‘ASU2017-07’)

In March 2017, the FASB issued ASU2017-07 primarily to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The guidance will require the net benefit cost to be split in the income statement. The service cost component will be included in operating income. The other components, including amortization of past service costs or credits, and settlement and curtailments amounts, will be reported separately outside of operating income. The amendment is effective for fiscal years beginning after December 15, 2017. Early adoption is permitted at the beginning of an annual period (in the first interim period) for which financial statements have not yet been issued. The Company does not anticipate the adoption of ASU2017-07 will have a material impact on its consolidated financial statements.

ASUNo. 2016-18 - Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force) (‘ASU2016-18’)

In November 2016, the FASB issued ASU2016-18, which requires entities to include in their cash and cash-equivalent balances in the statement of cash flows those amounts that are deemed to be restricted cash and restricted cash equivalents. The ASU does not define the terms “restricted cash” and “restricted cash equivalents.” The amendments are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company does not anticipate the adoption of ASU2016-18 will have a material impact on its consolidated financial statements.

ASUNo. 2016-16 - Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (‘ASU2016-16’)

In October 2016, the FASB issued ASU2016-16, which eliminates the exception for all intra-entity sales of assets other than inventory. As a result, a reporting entity would recognize the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs, even though thepre-tax effects of that transaction are eliminated in consolidation. Any deferred tax asset that arises in the buyer’s jurisdiction would also be

109

ON SEMICONDUCTOR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

recognized at the time of the transfer. The new guidance does not apply to intra-entity transfers of inventory. The income tax consequences from the sale of inventory from one member of a consolidated entity to another will continue to be deferred until the inventory is sold to a third party. The amendments are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company does not anticipate the adoption of ASU2016-16 will have a material impact on its consolidated financial statements.

ASU No.2016-15 - Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (‘ASU2016-15’)

In August 2016, the FASB issued ASU2016-15, which changes how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company does not anticipate the adoption of ASU2016-15 will have a material impact on its consolidated financial statements.

ASU No.2016-02 - Leases (Topic 842) (‘ASU2016-02’)

In February 2016, the FASB issued ASU2016-02, which amends the accounting treatment for leases. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Lessees (for capital and operating leases) and lessors (for sales-type leases, direct financing leases, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of ASU2016-02 may have on its consolidated financial statements.

ASUNo. 2014-09 - Revenue from Contracts with Customers (Topic 606) (‘ASU2014-09’),ASU No. 2015-14 - Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date(‘ASU 2015-14’), ASU No. 2016-08 - Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (‘ASU2016-08’), ASUNo. 2016-10 - Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing (‘ASU2016-10’) ASUNo. 2016-12 - Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients(‘ASU 2016-12’) and ASUNo. 2016-20 - Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers” (‘ASU2016-20’)

In May 2014, the FASB issued ASU2014-09, which applies to any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer ofnon-financial assets unless those contracts are within the scope of other standards supersedes the existing revenue recognition requirements in ASC Topic 605, “Revenue Recognition.” Pursuant to ASU2014-09, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange, as applied through a multi-step process to achieve that core principle. Subsequently, the FASB approved a deferral included in ASU2015-14 that permits public entities to

ON SEMICONDUCTOR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

apply the amendments in ASU2014-09 for annual reporting periods beginning after December 15, 2017, including interim reporting periods therein, and that would also permit public entities to elect to adopt the amendments as of the original effective date as applicable to reporting periods beginning after December 15, 2016. The new guidance allows for the amendment to be applied either retrospectively to each prior reporting period presented or retrospectively as a cumulative-effect adjustment as of the date of adoption. In March 2016, the FASB issued ASU2016-08, which clarifies the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU2016-10, which clarifies identifying performance obligations and the licensing implementation guidance. In May 2016, the FASB issued ASU2016-12, which improves certain aspects of ASC Topic 606 “Revenue from Contracts with Customers.” In December 2016, the FASB issued ASU2016-20, which improves certain aspects of ASC Topic 606 “Revenue from Contracts with Customers.” The effective date and transition requirements for ASU2016-08, ASU2016-10, ASU2016-12 and ASU2016-20 are the same as the effective date and transition requirements of ASU2014-09 (collectively, “the standard”).

The Company has evaluated the impact of the standard and concluded that the adoption will not have a material impact on its consolidated financial statements. The impact on the timing of revenue recognition on certain product development agreements is not expected to be material. The Company is in the final stages of documenting its conclusions on the evaluation of the terms of the customer contracts and arrangements for adoption of the standard on a modified retrospective basis on January 1, 2018.

Note 4:    Acquisitions, Divestitures and Licensing Transactions

The Company pursues strategic acquisitions and divestitures from time to time to leverage its existing capabilities and further build its business. Acquisitions are accounted for as business combinations pursuant to ASC 805 “Business Combinations.” Accordingly, acquisition costs are not included as components of consideration transferred and instead are accounted for as expenses in the period in which the costs are incurred. During the years ended December 31, 2017 and 2016, the Company incurred acquisition and divestiture related costs of approximately $3.2 million and $25.8 million, respectively, which are included in operating expenses on the Company’s Consolidated Statements of Operations and Comprehensive Income.

2017 Divestiture

On September 29, 2017, the Company entered into a Share Purchase Agreement with mCube, whereby mCube acquired 100% of the outstanding shares of Xsens Holding B.V., a wholly owned subsidiary of the Company, for cash consideration of $26.0 million (collectively, the “Xsens Transaction”). Twenty percent of the consideration, or $5.2 million, was deposited into an escrow account and the remaining $20.8 million was received on September 29, 2017. There were no indemnification liabilities identified and the escrow amount has been considered as part of the consideration in calculating the gain and included in other assets in the Consolidated Balance Sheet as of December 31, 2017. The escrow amount will be released to the Company upon satisfaction of any pending claims eighteen months after the date on which the Xsens Transaction closed. The Company recorded a gain of $12.5 million after writing off the carrying value of the assets and liabilities sold of $7.0 million and goodwill of $6.5 million. This gain has been presented as “Gain on divestiture of business” in the Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2017.

2016 Acquisition

On September 19, 2016, the Company acquired 100% of Fairchild, whereby Fairchild became a wholly-owned subsidiary of the Company. The purchase price totaled $2,532.2 million in cash and was funded by the Company’s borrowings against its Term Loan “B” Facility and a partial draw of the Revolving Credit Facility, as well as with cash on hand. See Note 8: “Long-Term Debt” for additional information.

For the period from September 19, 2016 to December 31, 2016, the Company recognized revenue of $411.5 million and a net loss of $34.5 million relating to Fairchild, which included charges for the amortization of fair market valuestep-up of inventory of $67.5 million, the amortization of acquired intangible assets and restructuring.

The following table presents the allocation of the purchase price for the acquisition of Fairchild, including the effects of the measurement period adjustments recorded in 2016 for the assets acquired and liabilities assumed based on their fair values (in millions):

	Purchase Price Allocation
Cash and cash equivalents		$           255.0
Receivables		227.3
Inventories		342.3
Other current assets		61.0
Property, plant and equipment		925.8
Goodwill		656.1
Intangible assets (excluding IPRD)		413.6
In-process research and development		134.2
Othernon-current assets		13.1
Total assets acquired		3,028.4
Accounts payable		79.4
Other current liabilities		168.1
Deferred tax liabilities		213.5
Othernon-current liabilities		35.2
Total liabilities assumed		496.2
Net assets acquired/purchase price		$        2,532.2

Acquired intangible assets included $134.2 million of IPRD assets, which are to be amortized over the useful life upon successful completion of the related projects. The value assigned to IPRD was determined by considering the importance of products under development to the overall development plan, estimating costs to develop the purchased IPRD into commercially viable products, estimating the resulting net cash flows from the projects when completed and discounting the net cash flows to their present value. The Company utilized a discount rate of 14.5% and cash flows from its significant products were expected to commence from 2017 and beyond.

Other acquired intangible assets of $413.6 million consisted of developed technology of $272.7 million (eleven year weighted-average useful life), customer relationships of $135.5 million (fifteen year useful life) and backlog

112

ON SEMICONDUCTOR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

of $3.0 million (six month useful life). The total weighted-average amortization period for the acquired intangibles is 12.1 years.

The acquisition produced $656.1 million of goodwill, of which $366.1 million was assigned to the Power Solutions Group and $290.0 million to the Analog Solutions Group. Goodwill is attributable to a combination of Fairchild’s assembled workforce, expectations regarding a more meaningful engagement with customers due to the scale of the combined Company and other synergies. Goodwill arising from the Fairchild acquisition is not deductible for tax purposes.

During the year ended December 31, 2016, the Company incurred $24.7 million in acquisition-related costs from the Fairchild acquisition. These costs are recorded in general and administrative expense in the Consolidated Statements of Operations and Comprehensive Income.

See Note 12: “Commitments and Contingencies” for information on contingent liabilities assumed from the acquisition of Fairchild.

Pro-Forma Results of Operations

2016 Divestiture

On August 25, 2016, the U.S. Federal Trade Commission (“FTC”) accepted a proposed consent order whereby, prior to the closing of the acquisition of Fairchild, the FTC required the Company to dispose of its IGBT business. In satisfaction of this requirement, on August 29, 2016, the Company sold the ignition IGBT business to Littelfuse. On the same day, the Company sold its transient voltage suppression diode and switching thyristor product lines (“Thyristor”) to Littelfuse. The sale of the ignition IGBT and Thyristor businesses was for $104.0 million in cash. In connection with the sale, the Company recorded a gain of $92.2 million after, among other things, transferring inventory of $4.1 million to Littelfuse, writing off goodwill of $3.4 million and

deferring $4.3 million of the proceeds representing the fair value of manufacturing services to be recognized in the future. This gain has been presented separately as “Gain on divestiture of business” in the Consolidated Statements of Operations and Comprehensive Income.

2016 Licensing Transaction

On December 19, 2016, the Company entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with HSET Electronic Tech (Hong Kong) Limited (“HSET”) to sell inventory and license patents related to its Mobile CIS business for $75.0 million. On April 7, 2017, the Company and HSET along with Huaian Imaging Device Manufacturer Corporation (“HIDM”) entered into the First Amendment to the Asset Purchase Agreement. The arrangement included the sale of $22.5 million of inventory, which has been recorded as revenue for the year ended December 31, 2017.

During 2017, the Company received the remaining $52.5 million and provided perpetual,non-exclusive licenses to certain technologies to HIDM. Of this, $10.0 million has been recorded as deferred licensing income to be recognized in the period in which certain qualification requirements of the technologies are achieved, or refunded to the buyer if qualification does not occur by June 21, 2018. The remaining $42.5 million, along with $2.6 million of withholding taxes borne by HIDM on the Company’s behalf, has been recognized as licensing income in the Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2017. The value of the licensed technologies in intangible assets amounting to $8.2 million has been fully amortized during 2017 as there are no additional expected future cash flows associated with these technologies.

Note 5:    Goodwill and Intangible Assets

Goodwill

Goodwill is tested for impairment at the reporting unit level, which is one level below the Company’s operating segments. The Company performed a qualitative assessment as part of the annual impairment analysis during the fourth quarter of 2017 and concluded that it is more likely than not that the fair value of its reporting units exceed their carrying amounts and a quantitative impairment test was not required. During 2016, a quantitative impairment test was performed to determine that the carrying amount of the Company’s goodwill for all of its reporting units was recoverable and a step two test was not required for any reporting unit.

The Company uses the income approach, based on estimated future cash flows, to perform the quantitative impairment test. These estimates include assumptions about future conditions such as future revenues, gross profits, operating expenses and industry trends. The Company considers other valuation methods, such as the cost approach or market approach, if it determines that these methods provide a more representative approximation of fair value. The material assumptions used for the income approach for periods when no impairment was necessary included projected net cash flows, a weighted-average discount rate of approximately 10.5% and a weighted-average long-term growth rate of 3%. The Company considered historical rates and current market conditions when determining the discount and growth rates to use in the Company’s analysis.

The Company incurred issuance costs of $18.3 million in connection with the issuance of the 1.00% Notes, of which $15.4 million were recorded as debt issuance costs and are being amortized using the effective interest method and $2.9 million were allocated to the conversion option (as further described below) and were recorded to equity. The 1.00% Notes are governed by an indenture between the Company, as the issuer, the guarantors named therein and Wells Fargo Bank, National Association, as trustee (the “1.00% Indenture”).

The Company’s use of the net proceeds from the offering included the following: (i) the funding of the cost of the convertible note hedge transactions described below (the cost of which was partially offset by the proceeds that the Company received from entering into the warrant transactions described below); (ii) funding the repurchase of $70.0 million of the Company’s common stock which was acquired from purchasers of the 1.00% Notes in privately negotiated transactions effected through one or more of the initial purchasers or their affiliates conducted concurrently with the issuance of the 1.00% Notes; and (iii) repayment of $350.0 million of borrowings outstanding under its Revolving Credit Facility. The remainder of the proceeds was intended for general corporate purposes, including additional share repurchases and potential acquisitions.

The notes bear interest at the rate of 1.00% per year from the date of issuance, payable semiannually in arrears on June 1 and December 1 of each year, beginning on December 1, 2015. The 1.00% Notes are fully and unconditionally guaranteed on a senior unsecured obligation basis by certain existing subsidiaries of the Company.

The 1.00% Notes are convertible by holders into cash and shares of the Company’s common stock at a conversion rate of 54.0643 shares of common stock per $1,000 principal amount of notes (subject to adjustment in certain events), which is equivalent to an initial conversion price of $18.50 per share of common stock. The Company will settle conversion of all 1.00% Notes validly tendered for conversion in cash and shares of the Company’s common stock, if applicable, subject to the Company’s right to pay the share amount in additional cash. Holders may convert their 1.00% Notes only under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on September 30, 2015, if the last reported sale price of common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (ii) during the fivebusiness-day period immediately following any five consecutivetrading-day period in which the trading price per $1,000 principal amount of 1.00% Notes for each day of such period was less than 98% of the product of the closing sale price of the Company’s common stock and the conversion rate; (iii) upon occurrence of the specified transactions described in the 1.00% Indenture; or (iv) on and after September 1, 2020. Upon conversion of the 1.00% Notes, the Company will deliver cash, shares of its common stock or a combination of cash and shares of its common stock, at the Company’s election. For a discussion of the dilutive effects for earnings per share calculations, see Note 9: “Earnings Per Share and Equity.”

The 1.00% Notes will mature on December 1, 2020. If a holder elects to convert its 1.00% Notes in connection with the occurrence of specified fundamental changes that occur prior to September 1, 2020, the holder will be entitled to receive, in addition to cash and shares of common stock equal to the conversion rate, an additional number of shares of common stock, in each case as described in the 1.00% Indenture. Notwithstanding these conversion rate adjustments, the 1.00% Notes contain an explicit limit on the number of shares issuable upon conversion.

In connection with the occurrence of specified fundamental changes, holders may require the Company to repurchase for cash all or part of their 1.00% Notes at a purchase price equal to 100% of the principal amount of the 1.00% Notes to be repurchased, plus accrued and unpaid interest to, but not including, the fundamental change repurchase date.

The 1.00% Notes, which are the Company’s unsecured obligations, will rank equally in right of payment to all of the Company’s existing and future unsubordinated indebtedness and will be senior in right of payment to all of the Company’s existing and future subordinated obligations. The 1.00% Notes will also be effectively subordinated to any of the Company’s or its subsidiaries’ secured indebtedness to the extent of the value of the assets securing such indebtedness. ON Semiconductor was the sole issuer of the 1.00% Notes.

In accordance with accounting guidance on embedded conversion features, the Company valued and bifurcated the conversion option associated with the 1.00% Notes from the respective host debt instrument, which is referred to as the debt discount, and initially recorded the conversion option of $110.4 million in stockholders’

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

equity. The resulting debt discount is being amortized to interest expense at an effective interest rate of 4.29% over the contractual terms of the 1.00% Notes.

The Company used $56.9 million of the net proceeds from the offering of its 1.00% Notes to concurrently enter into convertible note hedge and warrant transactions with certain of the initial purchasers of the 1.00% Notes. Pursuant to these transactions, the Company has the option to purchase initially (subject to adjustment for certain specified transactions) a total of 37.3 million shares of its common stock at a price of $18.50 per share. The total cost of the convertible note hedge transactions was $108.9 million. In addition, the Company sold warrants to certain bank counterparties whereby the holders of the warrants have the option to purchase initially (subject to adjustment for certain specified events) a total of 37.3 million shares of the Company’s common stock at a price of $25.96 per share. The Company received $52.0 million in cash proceeds from the sale of these warrants.

In aggregate, the purchase of the convertible note hedges and the sale of the warrants are intended to offset potential dilution from the conversion of the 1.00% Notes. As these transactions meet certain accounting criteria, the convertible note hedges and warrants are recorded in stockholders’ equity and are not accounted for as derivatives. The net cost incurred in connection with the convertible note hedge and warrant transactions was recorded as a reduction to additional paid in capital in the Consolidated Balance Sheet. All of the shares subject to the conversion of the 1.00% Notes and hedging transactions were reserved in the form of the Company’s treasury stock.

2.625% Notes, Series B

On November 17, 2016, the Company announced that it would be exercising its option to redeem the entire $356.9 million outstanding principal amount of the 2.625% Notes, Series B on December 20, 2016 pursuant to the terms of the 2.625% Notes, Series B Indenture. The holders of the 2.625% Notes, Series B had the right to convert their 2.625% Notes, Series B into shares of common stock of the Company at a conversion rate of 95.2381 shares per $1,000 principal amount until the close of business on December 19, 2016, which was equivalent to an initial conversion price of approximately $10.50 per share of common stock. The Company, at its election, could settle its conversion obligation with respect to the 2.625% Notes, Series B, with shares of common stock, cash or a combination thereof. The Company satisfied its obligation with respect to the 2.625% Notes, Series B tendered for conversion with cash. The final conversion was settled on January 26, 2017, resulting in an aggregate payment of approximately $445.0 million for the redemption and conversion of the 2.625% Notes, Series B. The equity component of the 2.625% Notes, Series B amounting to $32.9 million, representing the amounts previously recorded to additional paid in capital, was reclassified to mezzanine equity as of December 31, 2016. There was no loss on extinguishment of debt, and upon settlement, the balance in the mezzanine equity was reduced to zero and the remaining $55.7 million was recorded as a reduction to APIC.

Note 9:    Earnings Per Share and Equity

Earnings Per Share

Calculations of net income per common share attributable to ON Semiconductor Corporation are as follows (in millions, except per share data):

	For the years ended December 31,
	2017		2016		2015
Net income attributable to ON Semiconductor Corporation	$	810.7	$	182.1	$	206.2
Basic weighted average common shares outstanding		421.9		415.2		421.2
Add: Incremental shares for:
Dilutive effect of share-based awards		5.5		3.8		4.6
Dilutive effect of convertible notes		0.9		1.0		2.0
Diluted weighted average common shares outstanding		428.3		420.0		427.8
Net income per common share attributable to ON Semiconductor Corporation:
Basic	$	1.92	$	0.44	$	0.49
Diluted	$	1.89	$	0.43	$	0.48

Basic income per common share is computed by dividing net income attributable to ON Semiconductor Corporation by the weighted average number of common shares outstanding during the period.

The number of incremental shares from the assumed exercise of stock options and assumed issuance of shares relating to RSUs is calculated by applying the treasury stock method. Share-based awards whose impact is considered to be anti-dilutive under the treasury stock method were excluded from the diluted net income per share calculation. The excluded number of anti-dilutive share-based awards was approximately 0.2 million, 1.7 million and 1.3 million for the years ended December 31, 2017, 2016 and 2015, respectively.

The dilutive impact related to the Company’s 1.00% Notes, 1.625% Notes and 2.625% Notes, Series B is determined in accordance with the net share settlement requirements prescribed by ASC Topic 260, “Earnings Per Share”. Under the net share settlement calculation, the Company’s convertible notes are assumed to be convertible into cash up to the par value, with the excess of par value being convertible into common stock. A dilutive effect occurs when the stock price exceeds the conversion price for each series of the convertible notes. In periods when the share price is lower than the conversion price, the impact is anti-dilutive and therefore has no impact on the Company’s earnings per share calculations. Additionally, if the average price of the Company’s common stock exceeds $25.96 per share, with respect to the 1.00% Notes, or $30.70 per share, with respect to the 1.625% Notes, for a reporting period, the Company will also include the effect of the additional potential shares, using the treasury stock method, that may be issued related to the warrants that were issued concurrently with the issuance of the 1.00% Notes and 1.625% Notes, respectively. Prior to conversion, the convertible note hedges are not considered for purposes of the earnings per share calculations, as their effect would be anti-dilutive. Upon

conversion, the convertible note hedges are expected to offset the dilutive effect of the 1.00% Notes and 1.625% Notes, respectively, when the stock price is above $18.50 per share, with respect to the 1.00% Notes, and $20.72 per share, with respect to the 1.625% Notes.

Share Repurchase Program

On December 1, 2014, the Company announced a capital allocation policy (the “Capital Allocation Policy”) under which the Company intends to return to stockholders approximately 80 percent of free cash flow, less repayments of long-term debt, subject to a variety of factors, including our strategic plans, market and economic conditions and the Board’s discretion. For the purposes of the Capital Allocation Policy, the Company defines free cash flow as net cash provided by operating activities less purchases of property, plant and equipment. The Company also announced the 2014 Share Repurchase Program pursuant to the Capital Allocation Policy. Under the 2014 Share Repurchase Program, the Company is authorized to repurchase approximately $1.0 billion of its common shares over a four year period, exclusive of any fees, commissions or other expenses, subject to the same factors and considerations described above. The 2014 Share Repurchase Program was effective December 1, 2014.

The Company repurchased shares worth $25.0 million of the Company’s common stock in connection with the offering of the 1.625% Notes during the year ended December 31, 2017. Other than this, there were no repurchases of the Company’s common stock under its share repurchase program during the years ended December 31, 2017 and 2016, respectively, as the Company focused on the funding required for the Fairchild Transaction, and its associated debt.

Shares for Restricted Stock Units Tax Withholding

Treasury stock is recorded at cost and is presented as a reduction of stockholders’ equity in the accompanying consolidated financial statements. Shares with a fair market value equal to the applicable statutory minimum amount of the employee withholding taxes due, are withheld by the Company upon the vesting of RSUs to pay the applicable statutory minimum amount of employee withholding taxes and are considered common stock repurchases. The Company then pays the applicable statutory minimum amount of withholding taxes in cash. The amounts remitted in the years ended December 31, 2017 and 2016 were $28.1 million and $12.3 million, respectively, for which the Company withheld approximately 1.8 million and 1.3 million shares of common stock, respectively, that were underlying the RSUs that vested. None of these shares had been reissued or retired as of December 31, 2017, but may be reissued or retired by the Company at a later date. These repurchases do not count against the Company’s share repurchase program.

On February 17, 2010, the 2000 SIP expired and the Company ceased granting under the plan. Options granted pursuant to the 2000 SIP that remain outstanding continue to be exercisable or subject to vesting pursuant to the underlying option agreements.

On March 23, 2010, the Company adopted the Amended and Restated SIP, which was subsequently approved by the Company’s stockholders at the annual stockholder meeting on May 18, 2010 and reapproved by the Company’s stockholders at the annual stockholder meeting on May 20, 2015. The Amended and Restated SIP provides key employees, directors and consultants with various equity-based incentives as described in the plan document. The Amended and Restated SIP is administered by the Board of Directors or a committee thereof, which is authorized to determine, among other things, the key employees, directors or consultants who will receive awards under the plan, the amount and type of award, exercise prices or performance criteria, if applicable, and vesting schedules. On May 15, 2012, stockholders approved certain amendments to the Amended and Restated SIP to increase the number of shares of common stock subject to all awards under the Amended and Restated SIP by 33.0 million. On May 17, 2017, stockholders approved certain amendments to the Amended and Restated SIP to increase the number of shares of common stock subject to all awards under the Amended and Restated SIP by 27.9 million to 87.0 million, exclusive of shares of common stock subject to awards that were previously granted pursuant to the 2000 SIP that have or will become available for grant pursuant to the Amended and Restated SIP.

Generally, the options granted under the 2000 SIP and Amended and Restated SIP vest over a period of three to four years and have a contractual term of 10 years and 7 years, respectively. Under both plans, certain outstanding options vest automatically upon a change of control, as defined in the respective plan document, provided the option holder is employed by the Company on the date of the change of control. Certain other outstanding options may also vest upon a change of control if the Board of Directors of the Company, at its discretion, provides for acceleration of the vesting of said options. Generally, upon the termination of an option holder’s employment, all unvested options will immediately terminate and vested options will generally remain exercisable for a period of 90 days after the date of termination (one year in the case of death or disability).

Generally, RSUs granted under the 2000 SIP and the Amended and Restated SIP vest over three years or based on the achievement of certain performance criteria and are payable in shares of the Company’s stock upon vesting.

As of December 31, 2017, there was an aggregate of 39.0 million shares of common stock available for grant under the Amended and Restated SIP.

Note 11:    Employee Benefit Plans

Defined Benefit Plans

The Company maintains defined benefit plans for employees of certain of its foreign subsidiaries. Such plans conform to local practice in terms of providing minimum benefits mandated by law, collective agreements or customary practice. The Company recognizes the aggregate amount of all overfunded plans as assets and the aggregate amount of all underfunded plans as liabilities in its financial statements. The Company’s expected long-term rate of return on plan assets is updated at least annually, taking into consideration its asset allocation, historical returns on similar types of assets and the current economic environment. For estimation purposes, the Company assumes its long-term asset mix will generally be consistent with the current mix. The Company determines its discount rates using highly rated corporate bond yields and government bond yields.

Benefits under all of the Company’s plans are valued utilizing the projected unit credit cost method. The Company’s policy is to fund its defined benefit plans in accordance with local requirements and regulations. The funding is primarily driven by the Company’s current assessment of the economic environment and projected benefit payments of its foreign subsidiaries. The Company’s measurement date for determining its defined benefit obligations for all plans is December 31 of each year.

The Company recognizes actuarial gains and losses in the period the Company’s annual pension plan actuarial valuations are prepared, which generally occurs during the fourth quarter of each year, or during any interim period where a revaluation is deemed necessary.

Plan Assets

The Company’s overall investment strategy is to focus on stable and low credit risk investments aimed at providing a positive rate of return to the plan assets. The Company has an investment mix with a wide diversification of asset types and fund strategies that are aligned with each region and foreign location’s economy and market conditions. Investments in government securities are generally guaranteed by the respective government offering the securities. Investments in corporate bonds, equity securities, and foreign mutual funds are made with the expectation that these investments will give an adequate rate of long-term returns despite periods of high volatility. Other types of investments include investments in cash deposits, money market funds and insurance contracts. Asset allocations are based on the anticipated required funding amounts, timing of benefit payments, historical returns on similar assets and the influence of the current economic environment.

Environmental Contingencies

The Company’s headquarters in Phoenix, Arizona are located on property that is a “Superfund” site, which is a property listed on the National Priorities List and subject toclean-up activities under CERCLA. Motorola and Freescale have been involved in the cleanup ofon-site solvent contaminated soil and groundwater andoff-site contaminated groundwater pursuant to consent decrees with the State of Arizona. As part of the Company’s separation from Motorola in 1999, Motorola retained responsibility for this contamination, and Motorola and Freescale have agreed to indemnify the Company with respect to remediation costs and other costs or liabilities related to this matter.

The Company’s formerfront-end manufacturing location in Aizu, Japan is located on property where soil and ground water contamination was detected. The Company believes that the contamination originally occurred during a time when the facility was operated by a prior owner. The Company worked with local authorities to implement a remediation plan and has completed remaining remediation. The majority of the cost of remediation was covered by insurance. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be, material.

The Company’s manufacturing facility in the Czech Republic has ongoing remediation projects to respond to releases of hazardous substances that occurred during the years that this facility was operated by government-owned entities. The remediation projects consist primarily of monitoring groundwater wells locatedon-site andoff-site with additional action plans developed to respond in the event activity levels are exceeded. The government of the Czech Republic has agreed to indemnify the Company and its respective subsidiaries, subject to specified limitations, for remediation costs associated with this historical contamination. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be, material.

The Company’s design center in East Greenwich, Rhode Island is located on property that has localized soil contamination. In connection with the purchase of the facility, the Company entered into a Settlement Agreement and Covenant Not to Sue with the State of Rhode Island. This agreement requires that remedial actions be undertaken and a quarterly groundwater monitoring program be initiated by the former owners of the property. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be, material.

As a result of the acquisition of AMIS of 2008, the Company is a “primary responsible party” to an environmental remediation and cleanup at AMIS’s former corporate headquarters in Santa Clara, California. Costs incurred by AMIS include implementation of theclean-up plan, operations and maintenance of remediation systems, and other project management costs. However, AMIS’s former parent company, a subsidiary of Nippon Mining, contractually agreed to indemnify AMIS and the Company for any obligations relating to environmental remediation and cleanup at this location. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be, material.

Through its acquisition of Fairchild, the Company acquired a facility in South Portland, Maine. This facility has ongoing environmental remediation projects to respond to certain releases of hazardous substances that occurred prior to the leveraged recapitalization of Fairchild from its former parent company, National Semiconductor Corporation, which is now owned by Texas Instruments, Inc. Although the Company may incur certain liabilities with respect to these remediation projects, pursuant to the asset purchase agreement entered into in connection with the Fairchild recapitalization, National Semiconductor Corporation agreed to indemnify Fairchild, without limitation and for an indefinite period of time, for all future costs related to these projects. Under a 1999 asset purchase agreement pursuant to which Fairchild purchased the power device business of Samsung, Samsung agreed to indemnify Fairchild in an amount up to $150.0 million for remediation costs and other liabilities related to historical contamination at Samsung’s Bucheon, South Korea operations. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be, material.

Under a 2001 asset purchase agreement pursuant to which Fairchild purchased a manufacturing facility in Mountain Top, Pennsylvania, Intersil Corp. agreed to indemnify Fairchild for remediation costs and other liabilities related to historical contamination at the facility. Any costs to the Company incurred to respond to the above conditions and projects have not been, and are not expected to be, material, and any future payments the Company makes in connection with such liabilities are not expected to be material.

The Company was notified by the EPA that it has been identified as a PRP under CERCLA in the Chemetco Superfund matter. Chemetco, a defunct reclamation services supplier that operated in Illinois at what is now a Superfund site, has performed reclamation services for the Company in the past. The EPA is pursuing Chemetco customers for contribution to the site cleanup activities. The Company has joined a PRP group which is cooperating with the EPA in the evaluation and funding of the cleanup. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be, material.

limited to, material purchase commitments, agreements to mitigate collection risk, leases, utilities or customs guarantees. As of December 31, 2017, the Company’s Revolving Credit Facility included $15.0 million of availability for the issuance of letters of credit. There were $0.4 million letters of credit outstanding under the Revolving Credit Facility as of December 31, 2017, which reduces the Company’s borrowing capacity. The Company also had outstanding guarantees and letters of credit outside of its Revolving Credit Facility totaling $5.7 million as of December 31, 2017.

As part of obtaining financing in the ordinary course of business, the Company has issued guarantees related to certain of its capital lease obligations, equipment financing, lines of credit and real estate mortgages, which totaled $120.6 million as of December 31, 2017. The Company is also a guarantor of SCI LLC’snon-collateralized loan with SMBC, which had a balance of $122.7 million as of December 31, 2017. See Note 8: “Long-Term Debt” for additional information.

Based on historical experience and information currently available, the Company believes that it will not be required to make payments under the standby letters of credit or guarantee arrangements for the foreseeable future.

Indemnification Contingencies

The Company is a party to a variety of agreements entered into in the ordinary course of business pursuant to which it may be obligated to indemnify the other parties for certain liabilities that arise out of or relate to the subject matter of the agreements. Some of the agreements entered into by the Company require it to indemnify the other party against losses due to IP infringement, property damage (including environmental contamination), personal injury, failure to comply with applicable laws, the Company’s negligence or willful misconduct, or breach of representations and warranties and covenants related to such matters as title to sold assets.

The Company faces risk of exposure to warranty and product liability claims in the event that its products fail to perform as expected or such failure of its products results, or is alleged to result, in economic damage, bodily injury or property damage. In addition, if any of the Company’s designed products are alleged to be defective, the Company may be required to participate in their recall. Depending on the significance of any particular customer and other relevant factors, the Company may agree to provide more favorable rights to such customer for valid defective product claims.

The Company and its subsidiaries provide for indemnification of directors, officers and other persons in accordance with limited liability company operating agreements, certificates of incorporation,by-laws, articles of association or similar organizational documents, as the case may be. Section 145 of the Delaware General Corporation Law (“DGCL”) authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers under certain circumstances and subject to certain limitations. The terms of Section 145 of the DGCL are sufficiently broad to permit indemnification under certain circumstances for liabilities, including reimbursement of expenses incurred, arising under the Exchange Act. As permitted by the DGCL, the Company’s Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”), contains provisions relating to the limitation of liability and indemnification of directors and officers. The Certificate of Incorporation eliminates the personal liability of each of the Company’s directors to the fullest extent permitted by Section 102(b)(7) of the DGCL, as it may be amended or supplemented, and provides that the Company will indemnify its directors and officers to the fullest extent permitted by Section 145 of the DGCL, as amended from time to time.

Specifically, the Company has agreed that, for no fewer than six years following the Fairchild acquisition, the Company will: (a) indemnify and hold harmless each such indemnitee against losses and expenses (including advancement of attorneys’ fees and expenses) in connection with any proceeding asserted against the indemnified party in connection with such person’s servings as a director, officer, employee or other fiduciary of Fairchild or its subsidiaries prior to the effective time of the acquisition; (b) maintain in effect all provisions of the certificate of incorporation or bylaws of Fairchild or any of its subsidiaries or any other agreements of Fairchild or any of its subsidiaries with any indemnified party regarding elimination of liability, indemnification of officers, directors and employees and advancement of expenses in existence on the date of the Fairchild Agreement for acts or omissions occurring prior to the effective time of the acquisition; and (c) subject to certain qualifications, provide to Fairchild’s then current directors and officers an insurance and indemnification policy that provides coverage for events occurring prior to the effective time of the acquisition that is no less favorable than Fairchild’s then-existing policy, or, if insurance coverage that is no less favorable is unavailable, the best available coverage.

While the Company’s future obligations under certain agreements may contain limitations on liability for indemnification, other agreements do not contain such limitations and under such agreements it is not possible to predict the maximum potential amount of future payments due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under any of these indemnities have not had a material effect on the Company’s business, financial condition, results of operations or cash flows. Additionally, the Company does not believe that any amounts that it may be required to pay under these indemnities in the future will be material to the Company’s business, financial position, results of operations or cash flows.

Legal Matters

From time to time, the Company is party to various legal proceedings arising in the ordinary course of business, including indemnification claims, claims of alleged infringement of patents, trademarks, copyrights and other

intellectual property rights, claims of allegednon-compliance with contract provisions and claims related to alleged violations of laws and regulations. The Company regularly evaluates the status of the legal proceedings in which it is involved to assess whether a loss is probable or there is a reasonable possibility that a loss, or an additional loss, may have been incurred and determine if accruals are appropriate. If accruals are not appropriate, the Company further evaluates each legal proceeding to assess whether an estimate of possible loss or range of possible loss can be made for disclosure. Although litigation is inherently unpredictable, the Company believes that it has adequate provisions for any probable and estimable losses. It is possible, nevertheless, that the Company’s consolidated financial position, results of operations or liquidity could be materially and adversely affected in any particular period by the resolution of a legal proceeding. The Company’s estimates do not represent its maximum exposure. Legal expenses related to defense, negotiations, settlements, rulings and advice of outside legal counsel are expensed as incurred.

The Company is currently involved in a variety of legal matters that arise in the ordinary course of business. Based on information currently available, except as disclosed below, the Company is not involved in any pending or threatened legal proceedings that it believes could reasonably be expected to have a material adverse effect on its financial condition, results of operations or liquidity. The litigation process and the administrative process at the USPTO are inherently uncertain, and the Company cannot guarantee that the outcome of these matters will be favorable to it.

Patent Litigation with Power Integrations, Inc.

There are eight outstanding civil litigation proceedings with PI, five of which were pending between PI and various Fairchild entities (including Fairchild Semiconductor International, Inc., Fairchild Semiconductor Corporation, and Fairchild (Taiwan) Corporation, f/k/a System General Corporation (collectively referred to in thissub-section as “Fairchild”)), prior to the acquisition of Fairchild. The Company is vigorously defending the lawsuits filed by PI and believes that it has strong defenses. There are also over two dozen outstanding administrative proceedings between the parties at the USPTO in which each party is challenging the validity of the other party’s patents.

The outcome of any litigation is inherently uncertain and difficult to predict. Any estimate or statement regarding any reserve or the estimated range of possible losses is made solely in compliance with applicable GAAP requirements, and is not a statement or admission that the Company is or should be liable in any amount, or that any arguments, motions or appeals before any Court lack merit or are subject to impeachment. To the contrary, the Company believes that it has significant and meritorious grounds for judgment in its favor with respect to all of the PI cases and that the Company’s appeals or motions currently pending at the district court level will significantly reduce or eliminate all prior adverse jury verdicts. Subject to the foregoing, as of the date of the filing of this Form10-K, the Company estimates its range of possible losses for all PI cases to be between approximately $4 million and $20 million in the aggregate.

Power Integrations v. Fairchild Semiconductor International, Inc. et al. (October 20, 2004, Delaware,1:04-cv-01371-LPS): PI filed this lawsuit in 2004 in the U.S. District Court for the District of Delaware against Fairchild, alleging that certain of Fairchild’s pulse width modulation (“PWM”) integrated circuit products infringed U.S. patents owned by PI. The lawsuit sought a permanent injunction as well as money damages for Fairchild’s alleged infringement. In October 2006, a jury returned a willful infringement verdict and assessed damages against Fairchild. Fairchild voluntarily stopped U.S. sales and importation of those products in 2007 and

has been offering replacement products since 2006. In December 2008, the judge overseeing the case reduced the jury’s 2006 damages award from $34.0 million to approximately $6.1 million and ordered a new trial on the issue of willfulness. Following the new trial held in June 2009, the court found Fairchild’s infringement to have been willful, and in January 2011 the court awarded PI final damages in the amount of $12.2 million. Fairchild appealed the final damages award, willfulness finding, and other issues to the U.S. Court of Appeals for the Federal Circuit. In March 2013, the Court of Appeals vacated substantially all of the damages award, ruling that there was no basis upon which a reasonable jury could find Fairchild liable for induced infringement. The Court of Appeals also vacated the earlier judgment of willful patent infringement. The full Court of Appeals and the Supreme Court of the United States later denied PI’s request to review the Court of Appeals ruling. The Court of Appeals instructed the lower court to conduct further proceedings to determine damages based on approximately $750,000 worth of sales and imports of affected products, and tore-assess its finding that the infringement was willful. In December 2017, the lower court reinstated the willfulness finding, and the parties are currently working with the court to set a schedule to resolve the outstanding issues, including damages adequate to compensate PI.

Power Integrations v. Fairchild Semiconductor International, Inc. et al. (May 23, 2008, Delaware,1:08-cv-00309-LPS):This lawsuit was initiated by PI in 2008 in the U.S. District Court for the District of Delaware against Fairchild, alleging that certain other PWM products infringed several U.S. patents owned by PI. On October 14, 2008, Fairchild filed a patent infringement lawsuit against PI in the U.S. District Court for the District of Delaware, alleging that certain PI products infringed U.S. patents owned by Fairchild. Each lawsuit included claims for money damages and a request for a permanent injunction. These two lawsuits were consolidated and heard together in a jury trial in April 2012, during which the jury found that PI infringed one of the two U.S. patents owned by Fairchild and upheld the validity of both of the Fairchild patents. In the same verdict, the jury found that Fairchild infringed two of four U.S. patents asserted by PI and that Fairchild had induced its customers to infringe the asserted patents. (The court later ruled that Fairchild infringed one other asserted PI patent that the jury found was not infringed.) The jury also upheld the validity of the asserted PI patents, and the court entered a permanent injunction against Fairchild. Willfulness and damages were not considered in the April 2012 trial, but were reserved for subsequent proceedings. Fairchild and PI appealed the liability phase of this litigation to the U.S. Court of Appeals for the Federal Circuit, which heard arguments in July 2016 and issued a decision in December 2016. In the decision, the appeals court vacated the jury’s finding that Fairchild induced infringement of PI’s patents, held that one of PI’s patents was invalid, vacated the permanent injunction against Fairchild, reversed the jury’s finding that PI infringed the Fairchild patent, and remanded the case back to the lower court for further proceedings consistent with these rulings.

The Company is preparing for a trial later this year at which willfulness, inducement and money damages are expected to be addressed.

Power Integrations v. Fairchild Semiconductor International Inc. et al. (November 4, 2009, Northern District of California,3:09-cv-05235-MMC):In 2009, PI sued Fairchild in the U.S. District Court for the Northern District of California, alleging that several of Fairchild’s products infringe three of PI’s patents. Fairchild filed counterclaims asserting that PI infringed two Fairchild patents. During the initial trial in this matter in 2014, a jury found that Fairchild willfully infringed two PI patents, awarded PI $105.0 million in damages and found that PI did not infringe any Fairchild patent. In September 2014, the court granted a motion filed by Fairchild that sought to set aside the jury’s determination that it acted willfully, and held that, as a matter of law, Fairchild’s actions were not willful. In November 2014, in response to another post-trial motion filed by Fairchild, the trial

151

ON SEMICONDUCTOR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

court ruled that the jury lacked sufficient evidence on which to base its damages award and, consequently, vacated the $105.0 million verdict and ordered a second trial on damages. The second damages trial was held in December 2015, in which a jury awarded PI $139.8 million in damages. Fairchild filed a number of post-trial motions challenging the second damages verdict, but the court ruled against Fairchild on these motions and awarded PI approximately $7.0 million inpre-judgment interest. Following the court’s rulings on these issues, PI moved the court to reinstate the jury’s willfulness finding and sought enhanced damages and attorneys’ fees. On January 23, 2017, the court reinstated the jury’s willful infringement finding, but denied PI’s motion for enhanced damages and attorneys’ fees in its entirety. The Company has filed a notice of appeal with the U.S. Court of Appeals for the Federal Circuit with respect to the current damages award as well as the 2014 verdict finding that PI’s patents were infringed and valid. The appeal briefing is complete, and the parties are currently waiting for the Federal Circuit to schedule oral arguments. On May 26, 2017, the district court ordered Fairchild to obtain a bond for the judgment pending appeal, and on June 22, 2017, the district court accepted Fairchild’s bond and stayed execution of judgment. All claims of the two PI patents found to be infringed by Fairchild and that support the damages verdict have since been determined to be unpatentable in several inter partes review administrative proceedings described below. The impact of the USPTO’s unpatentability determinations on the district court judgment is uncertain at this stage of the proceedings.

Fairchild Semiconductor International Inc. et al. v. Power Integrations (May 1, 2012, Delaware,1:12-cv-00540-LPS): In May 2012, Fairchild sued PI in the U.S. District Court for the District of Delaware, and alleged that various PI products infringe Fairchild’s U.S. patents. PI filed counterclaims of patent infringement against Fairchild, asserting five PI patents. Of those five patents, the court granted Fairchild summary judgment of no infringement on one, and PI voluntarily withdrew a second and was forced to remove a third patent during the trial, which began in May 2015. In that trial, the jury found that PI induced infringement of Fairchild’s patent rights and awarded Fairchild $2.4 million in damages. The same jury found that Fairchild infringed a PI patent and awarded PI damages of $100,000. Based on the December 2016 appellate court decision in the litigation filed in Delaware in 2008 (described above), on July 13, 2017, the district court vacated the jury’s finding that PI infringed Fairchild’s patent. The court has yet to enter a final judgment in this case.

Power Integrations v. Fairchild Semiconductor International Inc. et al. (October 21, 2015, Northern District of California,3:15-cv-04854 MMC): In 2015, PI filed another complaint for patent infringement against Fairchild in the U.S. District Court for the Northern District of California, alleging Fairchild’s products willfully infringe two PI patents. In the complaint, PI is seeking a permanent injunction, unspecified damages, a trebling of damages, and an accounting of costs and fees. Fairchild answered and counterclaimed, alleging infringement by PI of four Fairchild patents related to aspects of PI’s products, and also seeking damages and a permanent injunction. The lawsuit is in its earliest stages, and has been stayed pending the outcome of the Company’s administrative challenges to the two PI patents asserted against Fairchild, which are described below. PI has also filed administrative challenges to Fairchild’s asserted patents.

Power Integrations v. ON Semiconductor Corporation, and Semiconductor Components Industries, LLC (November 1, 2016, Northern District of California,5:16-cv-06371-BLF and5:17-cv-03189):On August 11, 2016, ON Semiconductor Corporation and SCILLC (collectively, “ON Semi”) filed a lawsuit against PI in the U.S. District Court for the District of Arizona, alleging that PI infringed six patents and seeking a permanent injunction and money damages for the alleged infringement. The lawsuit also sought a claim for a declaratory judgment that ON Semi does not infringe several of PI’s patents. Rather than responding to ON Semi’s lawsuit in Arizona, PI filed a separate lawsuit in the U.S. District Court for the Northern District of California in November

152

ON SEMICONDUCTOR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

2016, alleging that ON Semi infringes six PI patents, including two of the three of ON Semi’s declaratory judgmentnon-infringement claims, and then moved the Arizona court to dismiss ON Semi’s lawsuit. Following various procedural motions, ON Semi’s Arizona action has been transferred to the U.S. District Court for the Northern District of California and consolidated with PI’s November 2016 lawsuit. The lawsuit is in its early stages, but the parties have begun to engage in discovery, with substantive developments expected throughout the course of 2018.

ON Semiconductor Corporation and Semiconductor Components Industries, LLC v. Power Integrations, Inc. (March 9, 2017, District of Delaware,1:17-cv-00247-LPS-CJB): On March 9, 2017, ON Semi filed a lawsuit against PI in the U.S. District Court for the District of Delaware, alleging that PI’s InnoSwitch family of products infringe six of ON Semi’s U.S. patents. Following some procedural motions, PI has since counterclaimed alleging infringement by ON Semi of seven of PI’s U.S. Patents. Both parties seek money damages and a permanent injunction. The lawsuit is in its early stages, but the parties have begun to engage in discovery, with substantive developments expected throughout the course of 2018.

Semiconductor Components Industries, LLC v. Power Integrations, Inc. (November 2017, Taiwan Intellectual Property Court,106-Ming-min-bu-Tzu-238): In November 2017, Semiconductor Components Industries, LLC filed a lawsuit against PI in Taiwan, alleging infringement by PI of certain of ON Semi’s Taiwanese patents. The lawsuit is in its early stages.

Administrative Challenges to PI’s Patents

In addition to the eight court proceedings described above, there are over two dozen pending inter partes review administrative proceedings between PI and ON Semi/Fairchild at the USPTO. Each of these administrative proceedings seeks to invalidate certain claims asserted in the various court proceedings. For two of the proceedings filed by ON Semi, both of which relate to the case filed in 2009 in the Northern District of California, the USPTO has issued a Final Written Decision finding that all of the claims challenged in those proceedings are unpatentable. PI may appeal the USPTO’s Final Written Decision regarding the unpatentability of those claims during 2018. In three of the proceedings, the USPTO has instituted a review of three ON Semi patents that are being asserted against PI, but the USPTO has not rendered a Final Written Decision in any of those three cases. All of the other proceedings remain pending, with further developments expected during 2018.

Litigation with Acbel Polytech, Inc.

On November 27, 2013, Fairchild and Fairchild Semiconductor Corporation were named as defendants in a complaint filed by Acbel Polytech, Inc. (“Acbel”) in the U.S. District Court for the District of Massachusetts. The lawsuit alleged a number of causes of action, including breach of warranty, fraud, negligence and strict liability, and has been docketed as Acbel Polytech, Inc. v. Fairchild Semiconductor International, Inc. et al, Case #1:13-CV-13046-DJC. On December 10, 2016, the Court issued an order on the Company’s motion for summary judgment dismissing all of Acbel’s claims except for claims alleging breach of implied warranties. A bench trial was held in June 2017. On December 27, 2017, the Court rendered a verdict in favor of the Fairchild defendants on the remaining implied warranty claims. On January 24, 2018, Acbel filed a notice of appeal.

Intellectual Property Matters

The Company faces risk to exposure from claims of infringement of the IP rights of others. In the ordinary course of business, the Company receives letters asserting that the Company’s products or components breach another party’s rights. These threats may seek that the Company make royalty payments, stop use of such rights, or other remedies.

Note 13:    Fair Value Measurements

Fair Value of Financial Instruments

The following table summarizes the Company’s financial assets and liabilities, excluding pension assets, measured at fair value on a recurring basis as of December 31, 2017 and December 31, 2016 (in millions):

Fair Value of Long-Term Debt, Including Current Portion

The carrying amounts and fair values of the Company’s long-term borrowings (excluding capital lease obligations, real estate mortgages and equipment financing) at December 31, 2017 and December 31, 2016 are as follows (in millions):

	December 31, 2017				December 31, 2016
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Long-term debt, including current portion
Convertible notes(1)	$	1,080.1	$	1,596.7	$	953.6	$	1,160.9
Long-term debt(1)	$	1,833.2	$	1,845.4	$	2,616.3	$	2,731.5

(1) Carrying amount shown is net of debt discounts and debt issuance costs. See Note 8: “Long-Term Debt” for additional information.

The fair value of the Company’s 1.00% Notes and 1.625% Notes were estimated based on market prices in active markets (Level 1). The fair value of other long-term debt was estimated based on discounting the remaining principal and interest payments using current market rates for similar debt (Level 2) at December 31, 2017 and December 31, 2016.

Fair Values Measured on aNon-Recurring Basis

Ournon-financial assets, such as property, plant and equipment, goodwill and intangible assets are recorded at fair value upon acquisition and are remeasured at fair value only if an impairment charge is recognized. The Company uses unobservable inputs to the valuation methodologies that are significant to the fair value measurements, and the valuations require management’s judgment due to the absence of quoted market prices. We determine the fair value of our held and used assets, goodwill and intangible assets using an income, cost or market approach as determined reasonable. See Note 5: “Goodwill and Intangible Assets” for a discussion of certain asset impairments.

As of December 31, 2017 and December 31, 2016, there were nonon-financial assets included in the Company’s Consolidated Balance Sheet that were remeasured at fair value on a nonrecurring basis.

The following table shows the adjustments to fair value of certain of the Company’snon-financial assets that had an impact on the Company’s results of operations during the years ended December 31, 2017, 2016 and 2015, respectively (in millions):

See Note 5: “Goodwill and Intangible Assets” and Note 6: “Restructuring, Asset Impairments and Other, Net” for additional information with respect to impairment charges.

Cost Method Investments

Investments in equity securities that do not qualify for fair value accounting are accounted for under the cost method. Accordingly, the Company accounts for investments in companies that it does not control under the cost method, as applicable. If a decline in the fair value of a cost method investment is determined to be other than temporary, an impairment charge is recorded and the fair value becomes the new cost basis of the investment. The Company evaluates all of its cost method investments for impairment; however, it is not required to determine the fair value of its investment unless impairment indicators are present.

As of each of December 31, 2017 and 2016, the Company’s cost method investments had a carrying value of $12.6 million and $12.3 million, respectively.

On October 10, 2017, ON Semiconductor and Fujitsu Semiconductor Limited (“Fujitsu”) announced that ON Semiconductor will purchase a 30 percent incremental share of Fujitsu’s8-inch wafer fab inAizu-Wakamatsu, resulting in a 40 percent ownership when the purchase is completed, at which time the Company would pay a purchase price of approximately $20.0 million in cash. The purchase is scheduled to be completed on April 1, 2018 (the “second closing date”), subject to certain regulatory approvals and other customary closing conditions. Subject to the fulfillment of certain conditions, the Company will be required to increase its ownership to 60 percent between one and six months following the second closing date (the “third closing date”) and will be required to increase its ownership to 100 percent between nine and 18 months following the third closing date.

Note 14:    Financial Instruments

Foreign Currencies

As a multinational business, the Company’s transactions are denominated in a variety of currencies. When appropriate, the Company uses forward foreign currency contracts to reduce its overall exposure to the effects of currency fluctuations on its results of operations and cash flows. The Company’s policy prohibits trading in currencies for which there are no underlying exposures, or entering into trades for any currency to intentionally increase the underlying exposure.

The Company primarily hedges existing assets and liabilities associated with transactions currently on its balance sheet, which are undesignated hedges for accounting purposes.

At December 31, 2017 and 2016, the Company had net outstanding foreign exchange contracts with net notional amounts of $130.5 million and $95.9 million, respectively. Such contracts were obtained through financial institutions and were scheduled to mature within one to three months from the time of purchase. Management believes that these financial instruments should not subject the Company to increased risks from foreign exchange movements because gains and losses on these contracts should offset losses and gains on the underlying assets, liabilities and transactions to which they are related.

The Company is exposed to credit-related losses if counterparties to its foreign exchange contracts fail to perform their obligations. As of December 31, 2017, the counterparties to the Company’s foreign exchange contracts, as well as the cash flow hedges described below, are held at financial institutions which the Company believes to be highly rated and no credit-related losses are anticipated. Amounts receivable or payable under the contracts are included in other current assets or accrued expenses in the accompanying Consolidated Balance Sheet. For the years ended December 31, 2017, 2016 and 2015, realized and unrealized foreign currency transactions totaled a $6.3 million loss, a $0.7 million gain and a $1.5 million loss, respectively, and are included in other income and expenses in the Company’s Consolidated Statements of Operations and Comprehensive Income.

Cash Flow Hedges

All derivatives are recognized on the balance sheet at their fair value and classified based on the instrument’s maturity date.

Interest rate risk

The Company uses interest rate swap contracts to mitigate its exposure to interest rate fluctuations associated with the Term Loan “B” Facility. The Company does not use such swap contracts for speculative or trading purposes.

To partially offset the variability of future interest payments on the outstanding Term Loan “B” Facility arising from changes in LIBOR rates, on January 11, 2017, the Company entered into interest rate swap agreements with three financial institutions for notional amounts totaling $500.0 million (effective as of January 11, 2017), $750.0 million (effective as of December 29, 2017) and $1.0 billion (effective as of December 31, 2018) with expiry dates of December 29, 2017, December 31, 2018 and December 31, 2019, respectively. These agreements effectively hedge some of the future variable rate LIBOR interest expense to a fixed rate interest expense. The derivative instruments qualified for accounting as a cash flow hedge in accordance with ASC 815, and the Company designated it as such. The Company has performed an effectiveness assessment and concluded that there is no ineffectiveness during the year ended December 31, 2017.

The Company did not have any interest rate swap contracts outstanding during the year ended December 31, 2016.

Foreign currency risk

The purpose of the Company’s foreign currency hedging activities is to protect the Company from the risk that the eventual cash flows resulting from transactions in foreign currencies will be adversely affected by changes in exchange rates. The Company enters into forward contracts that are designated as foreign currency cash flow hedges of selected forecasted payments denominated in currencies other than U.S. dollars.

For the years ended December 31, 2017 and 2016, the Company recorded a net loss of zero and $0.2 million, respectively, associated with cash flow hedges recognized as a component of cost of revenues. The Company did not have outstanding derivatives for its foreign currency exposure designated as cash flow hedges as of December 31, 2017 and 2016.

See Note 16: “Changes in Accumulated Other Comprehensive Loss” for the effective amounts related to derivative instruments designated as cash flow hedges affecting accumulated other comprehensive loss and the Company’s Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2017.

Convertible Note Hedges

The Company entered into convertible note hedges in connection with the issuance of the 1.00% Notes and 1.625% Notes. See Note 8: “Long-Term Debt” for further details.

Other

At December 31, 2017, the Company had no outstanding commodity derivatives, currency swaps or options relating to either its debt instruments or investments. The Company does not hedge the value of its equity investments in its subsidiaries or affiliated companies.

(2) The Company has included the benefit related to the change in valuation allowance on federal foreign tax credits which were previously set to expire unutilized but were utilized against the expense related to the mandatory repatriation tax $33.0 million or 6.0%, in the line “Impact of U.S. Tax Reform and related effects”

The Company’s effective tax rate for 2017 was a benefit of 48.5%, which differs from the U.S. federal statutory income tax rate of 35% primarily due to U.S. tax reform codified under the Tax Act. The Company’s effective tax rate for 2016 was a benefit of 2.2%, which differs from the U.S. federal statutory income tax rate of 35% primarily due to the release of its U.S. and Japan valuation allowances, partially offset by the reversal of the prior years’ indefinite reinvestment assertion. The Company’s effective tax rate for 2015 was a provision of 4.9%, which differs from the U.S. federal statutory income tax rate of 35% primarily due to its change in valuation allowance, deemed dividend income from foreign subsidiaries and tax rate differential in its foreign subsidiaries.

The tax effects of temporary differences in the recognition of income and expense for tax and financial reporting purposes that give rise to significant portions of the net deferred tax asset (liability) as of December 31, 2017 and December 31, 2016 are as follows (in millions):

On December 22, 2017, the U.S. enacted comprehensive tax legislation, the Tax Act. The Tax Act reduces the U.S. federal corporate tax rate from 35% to 21%, and requires companies to pay aone-time mandatory repatriation tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain future foreign earnings. In December 2017 the SEC staff issued Staff Accounting Bulletin No. 118,Income Tax Accounting Implications of the Tax Cuts and Jobs Act(“SAB 118”), which allows the Company to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. As of December 31, 2017, the Company has not completed its accounting for the tax effects of the enactment of the Tax Act; however, in certain cases, specifically as follows, the Company has made a reasonable estimate of (i) the effects on its existing deferred tax balances and (ii) the effects of theone-time mandatory repatriation tax. The Company has recognized a provisional tax benefit of $449.9 million in the year ended December 31, 2017 associated with the items it could reasonably estimate as described in the

reconciliation of the U.S. federal statutory income tax rate to the Company’s effective income tax rate table. The Company is still analyzing the Tax Act and refining its calculations, which could potentially impact the measurement of its tax balances. The Company expects to complete its analysis within the measurement period in accordance with SAB 118.

As of December 31, 2017, all benefits related to excess tax deductions from employee equity exercises are included in the Company’s NOL deferred tax asset due to the adoption of ASU2016-09 as of the first quarter of 2017. As of December 31, 2016, the Company’s deferred tax assets do not include $194.5 million of excess tax deductions from employee equity exercises.

As of December 31, 2017 and 2016, the Company had approximately $1,198.6 million and $1,203.6 million, respectively, of federal NOL carryforwards, before reduction for uncertain tax positions, which are subject to annual limitations prescribed in Section 382 of the Code. If not utilized, a portion of the NOLs will expire in varying amounts from 2021 to 2036.

As of December 31, 2017 and 2016, the Company had approximately $46.0 million and $211.9 million, respectively, of federal credit carryforwards, before consideration of valuation allowance or reduction for uncertain tax positions, which are subject to annual limitations prescribed in Section 383 of the Code. The decrease is primarily due to utilization of $191.1 million of credits to offset the mandatory repatriation tax liability. If not utilized, a portion of the credits will expire in varying amounts from 2033 to 2037.

As of December 31, 2017 and 2016, the Company had approximately $790.3 million and $1,191.2 million, respectively, of state NOL carryforwards, before consideration of valuation allowance or reduction for uncertain tax positions. The decrease is primarily due to expiration. If not utilized, a portion of the NOLs will expire in varying amounts from 2018 to 2037. As of December 31, 2017 and 2016, the Company had $107.2 million and $129.0 million, respectively, of state credit carryforwards before consideration of valuation allowance or reduction for uncertain tax positions. If not utilized, a portion of the credits will begin to expire in varying amounts starting in 2018.

As of December 31, 2017 and 2016, the Company had approximately $1,103.0 million and $1,078.8 million, respectively, of foreign NOL carryforwards, before consideration of valuation allowance or reduction for uncertain tax positions. If not utilized, a portion of the NOLs will begin to expire in varying amounts starting in 2018. As of December 31, 2017 and 2016, the Company had $65.3 million and $50.5 million, respectively, of foreign credit carryforwards before consideration of valuation allowance. The majority of these credits have an indefinite life and do not expire.

In 2016, the Company reassessed its need for a valuation allowance for the Japan consolidated group. Due to the Company’s recent trend of positive operating results, which resulted in the Japan group being in a cumulative twelve-quarter income position as of the period ended December 31, 2016, as well as the realignment of the former System Solutions Group segment, the Company realized an $89.4 million net tax benefit related to the release of a portion of its valuation allowance, to reflect the amount of its deferred tax assets which are expected to be realized in future years. The Company continues to maintain a valuation allowance on a portion of its Japan NOLs, or $302.0 million, which expire in varying amounts from 2018 to 2024.

In addition to the valuation allowance mentioned above on Japan NOLs, as of December 31, 2017 and 2016, the Company continues to maintain a full valuation allowance on its U.S. state deferred tax assets, and a valuation allowance on foreign NOLs and tax credits in certain other foreign jurisdictions.

The consummation of the Fairchild acquisition during 2016 caused the Company to reassess its prior years’ indefinite reinvestment assertion because of the U.S. debt incurred to fund the acquisition. See Note 8: “Long-Term Debt” for additional information. This resulted in a change in judgment regarding the Company’s future cash flows by jurisdiction and its prior years’ indefinite reinvestment assertion. The change in assertion, which resulted in recording a deferred tax liability for future U.S. taxes, had a direct impact on the Company’s judgment about the realizability of its U.S. federal deferred tax assets which resulted in a release of valuation allowance. The change in the Company’s prior years’ indefinite reinvestment assertion resulted in an increase to income tax expense of $310.8 million, which was partially offset by a benefit of $267.9 million relating to the release of valuation allowance. The reversal of the prior years’ indefinite reinvestment assertion and release of the U.S. federal valuation allowance did not have an effect on the Company’s cash taxes. At December 31, 2016, the Company was not indefinitely reinvested with respect to any of its foreign earnings.

In 2017, the Company reevaluated its indefinite reinvestment assertion because of the fundamental change in the U.S. approach to taxing international operations under the Tax Act. As a result, the Company has indefinitely reinvested certain foreign earnings. Therefore, tax has not been recognized on the excess of the amount for financial reporting over the tax basis of investments in its foreign subsidiaries that are considered indefinitely reinvested. The excess of the amount for financial reporting over the tax basis for which the Company is indefinitely reinvested is $226.3 million as of December 31, 2017, and the related unrecognized deferred income tax liability is $9.9 million. However, substantially all of the Company’s foreign earnings continue to not be indefinitely reinvested at December 31, 2017.

The Company maintains liabilities for uncertain tax positions. These liabilities involve considerable judgment and estimation and are continuously monitored by management based on the best information available, including changes in tax regulations, the outcome of relevant court cases, and other information. The Company is currently under examination by various taxing authorities. Although the outcome of any tax audit is uncertain, the Company believes that it has adequately provided in its consolidated financial statements for any additional taxes that the Company may be required to pay as a result of such examinations. If the payment ultimately proves not to be necessary, the reversal of these tax liabilities would result in tax benefits being recognized in the period the Company determines such liabilities are no longer necessary. However, if an ultimate tax assessment exceeds the Company’s estimate of tax liabilities, additional tax expense will be recorded. The impact of such adjustments could have a material impact on the Company’s results of operations in future periods.

For the period ended December 31, 2016, the Company performed a U.S. R&D tax credit study which covered the years from 2012 to 2015. The results of the study were recorded during the period ended December 31, 2016. As a result the uncertain tax position related to the outcome of the prior year study was also recorded.

Included in the December 31, 2017 balance of $114.8 million is $114.0 million related to unrecognized tax positions that, if recognized, would impact the annual effective tax rate. Although the Company cannot predict the timing of resolution with taxing authorities, if any, the Company believes it is reasonably possible that its unrecognized tax positions will be reduced by $8.3 million in the next 12 months due to settlement with tax authorities or expiration of the applicable statute of limitations.

The Company recognizes interest and penalties accrued in relation to unrecognized tax benefits in tax expense. The Company recognized approximately $1.5 million of tax expenses for interest and penalties during the year ended December 31, 2017, and recognized approximately $0.5 million and $0.9 million of tax expenses for interest and penalties during the years ended December 31, 2016 and 2015, respectively. The Company had approximately $5.9 million, $4.4 million, and $3.9 million of accrued interest and penalties at December 31, 2017, 2016, and 2015, respectively.

Tax years prior to 2013 are generally not subject to examination by IRS except for items involving tax attributes that have been carried forward to tax years whose statute of limitations remains open. The Company is not currently under IRS examination. For state returns, the Company is generally not subject to income tax examinations for years prior to 2012. The Company is also subject to routine examinations by various foreign tax jurisdictions in which it operates. With respect to major jurisdictions outside the United States, the Company’s subsidiaries are no longer subject to income tax audits for years prior to 2007. The Company is currently under audit in the following significant jurisdictions: China, Malaysia, Philippines, Singapore and Vietnam.

Note 18:    Segment Information

During the third quarter of 2016, the Company realigned its segments into three operating segments to optimize efficiencies resulting from the acquisition of Fairchild. These operating segments also represent its three reporting segments: Power Solutions Group, Analog Solutions Group and Image Sensor Group. The results of the System Solutions Group, which was previously the Company’s fourth operating segment, and which did not have goodwill, are now part of the three operating segments and previously-reported information has been presented based on the new structure to reflect the current organizational structure. The Company’s Power and Analog Solutions Groups include the business acquired in the Fairchild Transaction. See Note 4: “Acquisitions, Divestitures and Licensing Transactions” for additional information with respect to the Company’s recent acquisitions.

Each of the Company’s major product lines has been examined and each product line has been assigned to a reportable segment, as illustrated in the table below, based on the Company’s operating strategy. Because many products are sold into differentend-markets, the total revenue reported for a segment is not indicative of actual sales in theend-market associated with that segment, but rather is the sum of the revenue from the product lines assigned to that segment. These segments represent the Company’s view of the business and as such are used to evaluate progress of major initiatives and allocation of resources.

The Company’s wafer manufacturing facilities fabricate ICs for all business units, as necessary, and their operating costs are reflected in the segments’ cost of revenues on the basis of product costs. Because operating segments are generally defined by the products they design and sell, they do not make sales to each other. The Company does not discretely allocate assets to its operating segments, nor does management evaluate operating segments using discrete asset information.

In addition to the operating and reporting segments mentioned above, the Company also operates global operations, sales and marketing, information systems, finance and administration groups that are led by vice presidents who report to the Chief Executive Officer. A portion of the expenses of these groups are allocated to the segments based on specific and general criteria and are included in the segment results reported below. The Company does not allocate income taxes or interest expense to its operating segments as the operating segments are principally evaluated on gross profit. Additionally, restructuring, asset impairments and other, net and certain other manufacturing and operating expenses, which include corporate research and development costs, unallocated inventory reserves and miscellaneous nonrecurring expenses, are not allocated to any segment.

Revenues and gross profit for the Company’s reportable segments for the years ended December 31, 2017, 2016 and 2015, respectively, are as follows (in millions):
