PART I


Item 1.	Business

General

We are a leading global supplier of analog and mixed-signal semiconductor products and were incorporated in Delaware in 1960. We design, develop, manufacture and market a wide range of products for commercial applications, the majority of which are sold into the enterprise computing, communications, high-end consumer and industrial end-markets.

Enterprise Computing : datacenters, passive optical networks, desktops, notebooks, servers, monitors, printers and other computer peripherals.

Communications : base stations, optical networks, carrier networks, switches and routers, cable modems, wireless LAN and other communication infrastructure equipment.

High-End Consumer : handheld products, smartphones, set-top boxes, digital televisions, tablets, digital video recorders and other consumer equipment.

Industrial : video broadcast equipment, automated meter reading, Internet of Things ("IoT"), smart grid, military and aerospace, medical, security systems, automotive, industrial and home automation and other industrial equipment.

Our end-customers are primarily original equipment manufacturers ("OEMs") and their suppliers, including Alphabet Inc., Cisco Systems, Inc., Huawei Technologies Co., Ltd., LG Electronics, Sharp Corporation, Itron, Inc., Sonova International, Samsung Electronics Co. Ltd. and ZTE Corporation.

Overview of the Semiconductor Industry

The semiconductor industry is broadly divided into analog and digital semiconductor products. Analog semiconductors condition and regulate "real world" functions such as temperature, speed, sound and electrical current. Digital semiconductors process binary information, such as that used by computers. Mixed-signal devices incorporate both analog and digital functions into a single chip and provide the ability for digital electronics to interface with the outside world.

The market for analog and mixed-signal semiconductors differs from the market for digital semiconductors. The analog and mixed-signal industry is typically characterized by longer product life cycles than the digital industry. In addition, analog semiconductor manufacturers tend to have lower capital investment requirements for manufacturing because their facilities tend to be less dependent than digital producers on state-of-the-art production equipment to manufacture leading edge process technologies. The end-product markets for analog and mixed-signal semiconductors are more varied and more specialized than the relatively standardized digital semiconductor product markets.

Another difference between the analog and digital markets is the amount of available talented labor. The analog industry relies more heavily than the digital industry on design and applications talent to distinguish its products from one another. Digital expertise is extensively taught in universities due to its overall market size, while analog and mixed-signal expertise tends to be learned over time based on experience and hands-on training. Consequently, personnel with analog training are scarcer than digital trained engineers. This has historically made it more difficult for new suppliers in the analog market to quickly develop products and gain significant market share.

Advancements in digital signal processing technology typically drive the need for corresponding advancements in analog and mixed-signal solutions. We believe that the diversity of our applications allows us to take advantage of areas of relative market strength and reduces our vulnerability to competitive pressure in any one area.

Business Strategy

Our objective is to be a leading supplier of analog and mixed-signal semiconductor devices to the fastest growing segments of our target markets. We intend to leverage our pool of skilled technical personnel to develop new products, or, where appropriate, use strategic acquisitions or small strategic investments to either accelerate our position in the fastest growing areas or to gain entry into these areas. In order to capitalize on our strengths in analog and mixed-signal processing design, development and marketing, we intend to pursue the following strategies:

Leverage our rare analog/mixed signal design expertise

We have developed a strategy to invest heavily in human resources needed to define, design and market high-performance analog and mixed signal platform products. We have built a team of experienced engineers who combine industry expertise with advanced semiconductor design expertise to meet customer requirements and enable our customers to get their products to market rapidly. We intend to leverage this strategy to achieve new levels of integration, power reduction and performance, enabling our customers to achieve differentiation in their end systems.

Continue to release proprietary new products, achieve new design wins, and cross-sell products

We are focused on developing unique, new, proprietary products that bring value to our target customers in our target markets. These products are typically differentiated in performance but are priced competitively. We also focus on achieving design wins for our products with current and future customers. Design wins are indications by the customer that they intend to incorporate our products into their product designs. Although we believe that a design win is an indicator of future potential growth, it does not inevitably result in us being awarded business or receiving a purchase commitment. Our technical talent works closely with our customers in securing design wins, defining new products and in implementing and integrating our products into their systems. We also focus on selling our complete portfolio of products to our existing customers, as we believe the technical expertise of our marketing and sales team allows us to identify and capitalize on cross-selling opportunities.

Focus on fast-growing market segments and regions

We have chosen to target the analog/mixed signal sub-segments of some of the most exciting and fastest growing end-markets. We participate in these markets by focusing on specific product areas within the analog and mixed-signal market, including products for enterprise computing equipment, high-end consumer equipment, communications infrastructure and certain broad-based industrial markets. All of these markets are characterized by their need for leading-edge, high-performance analog and mixed-signal semiconductor technologies.

The enterprise computing, communications, high-end consumer and industrial end-markets we supply are characterized by several trends that we believe drive demand for our products. The key trends that we believe are significant for our future growth include:


•	Increasing bandwidth over high-speed networks, fueling growth in high speed multimedia transmission


•	Increasing electronic system requirements for smaller, lighter, more highly integrated and feature rich mobile devices


•	Increasing need for more efficient energy management in the home and in industrial environments and the proliferation of "green" standards


•	Increasing demands for Internet connectivity to low power sensors

Our products address these market trends by providing solutions that are ultra-low power thus extending battery life, small form factor enabling smaller more mobile devices, highly integrated enabling more functionality within devices and high performance enabling product differentiation within our customer base. Additionally, as communications functions are increasingly integrated into a range of systems and devices, these products require analog sensing, processing and control capabilities, which increases the number and size of our end-markets.

Leverage outsourced semiconductor fabrication capacity

We outsource most of our manufacturing in order to focus more of our resources on designing, developing and marketing our products. Our primary outside wafer foundries are based in China, Israel, the United States and Taiwan. We believe that outsourcing provides us numerous benefits, including capital efficiency, the flexibility to adopt and leverage emerging process technologies without significant investment risk, and a more variable cost of goods, which provides us with greater operating flexibility.

Products and Technology

We design, develop, manufacture and market high-performance analog and mixed-signal semiconductor products. We operate and account for results in one reportable segment through four product lines: Signal Integrity, Protection, Wireless and Sensing and Power and High-Reliability.

On January 13, 2015, we completed the acquisition of select assets of EnVerv, Inc. ("EnVerv"), a privately held company developing innovative products in the Smart Grid and Power Line Communication ("PLC") market place. This transaction, which was accounted for using the acquisition method of accounting, complements our business in the Metering and Machine to Machine ("M2M") and IoT markets. It is expected that the EnVerv PLC platform combined with our LoRa® devices and

wireless radio frequency ("RF") technology platform will create a highly-differentiated and compelling offering to the energy management, smart grid, IoT and residential gateway markets.

On March 4, 2015, we completed the acquisition of Triune Systems, LLC. ("Triune"), a privately-held supplier of wireless charging, isolated switching and power management platforms targeted at high and low power, high efficiency applications. This transaction, which was accounted for using the acquisition method of accounting, expanded our power management portfolio.

Beginning in fiscal year 2016, we split the product line previously known as Protection, Power and High-Reliability into two new product lines now referred to as the Protection Products Group and the Power and High-Reliability Products Group. The presentation of historical performance of these product lines has been recast for consistency for fiscal year 2015.

Our product lines include:

Signal Integrity Products. We design, develop and market a portfolio of optical communications, broadcast video and backplane products used in a wide variety of enterprise computing, industrial, communications and high-end consumer applications. Our comprehensive portfolio of integrated circuits ("ICs") for optical transceivers, backplane applications and high-speed interfaces ranges from 100Mbps to 100Gbps and supports key industry standards such as Fibre Channel, Infiniband, Ethernet, passive optical networks ("PON") and SONET. Our broadcast video products offer advanced solutions for next generation video formats, ever increasing data rates and evolving input/output ("I/O") and distance requirements.

Protection Products. We design, develop and market high performance protection devices, which are often referred to as transient voltage suppressors ("TVS"). TVS devices provide protection for electronic systems where voltage spikes (called transients), such as electrostatic discharge ("ESD"), electrical over stress ("EOS") or secondary lightning surge energy, can permanently damage sensitive complementary metal-oxide-semiconductor ("CMOS") ICs. Our portfolio of protection solutions include filter and termination devices that are integrated with the TVS device. Our products provide robust protection while preserving signal integrity in high-speed communications, networking and video interfaces. These products also operate at very low voltage. Our protection products can be found in a broad range of applications including smart phones, LCD TVs, set-top boxes, tablets, computers, notebooks, base stations, routers, automobile and industrial instruments.

Wireless and Sensing Products. We design, develop and market a portfolio of specialized RF products used in a wide variety of industrial, medical and communications applications, and specialized sensing products used in industrial and consumer applications. Our wireless products feature industry leading and longest range industrial, scientific and medical radio, enabling a lower total cost of ownership and increased reliability in all environments. This makes these products particularly suitable for M2M and IoT applications. Our unique sensing interface platforms can interface to any sensor and output digital data in any form. Specifically, the proximity sensing capability of our devices enable advanced user interface solutions for mobile and consumer products. Our wireless and sensing products can be found in a broad range of applications in the industrial, medical and consumer markets.

Power and High-Reliability Products. We design, develop and market power product devices that control, alter, regulate and condition the power within electronic systems. The highest volume product types within the power product line are switching voltage regulators, combination switching and linear regulators, smart regulators, isolated switches and charge pumps, and wireless charging. Our Power products feature highly integrated functionality for the communications, industrial and computing markets and low-power, small form factor and high-efficiency products for smart phones and other mobile devices, notebook computers, computer peripherals and other consumer devices. The primary application for these products is power regulation for enterprise computing, communications, high-end consumer and industrial systems. Our high-reliability discrete semiconductor products are comprised of rectifiers, assemblies (packaged discrete rectifiers) and other products that are typically used to convert alternating currents into direct currents and to protect circuits against very high voltage spikes or high current surges.

Our High-Reliability products can be found in a broad range of applications including industrial, military, medical, automotive, aerospace and defense systems, including satellite communications.

Systems Innovation Group. Prior to the third quarter of fiscal year 2017, we had a Systems Innovation Group which combined the analog/mixed signal design competencies from our previous Sierra Monolithics, Inc. ("SMI") and Gennum Corporation ("Gennum") acquisitions and was chartered with developing innovative analog/mixed signal intellectual property (“IP”) for emerging systems.

On August 5, 2016, we completed the divestiture of our Snowbush IP business (the remaining part of our Systems Innovation Group) to Rambus Inc. ("Rambus") for $32.0 million in cash along with the opportunity to receive additional payments from Rambus through 2022 based upon a percentage of sales by Rambus of new products expected to be developed by Rambus from

the disposed assets. In fiscal year 2017, we recorded a gain of $25.5 million on the disposition of this business. Other than this gain, the divestiture did not and is not expected to have a material impact on our consolidated financial statements. Following the divestiture, beginning in the third quarter of fiscal year 2017, we no longer have a Systems Innovation Group.

Seasonality

Historically, our results have reflected some seasonality, with demand levels generally being slightly lower in the industrial and high-end consumer products end-markets during the first and fourth quarters of our fiscal year in comparison to the second and third quarters.

Intellectual Capital and Product Development

The development of IP and the resulting proprietary products is a critical success factor for us. Recruiting and retaining key technical talent is the foundation for designing, developing and selling this IP, in the form of new proprietary products, in the global marketplace. Our ability to recruit and retain our engineering talent is one of the keys to maintaining our competitive advantage. Historically, we have been successful in retaining our key engineering staff and recruiting new talent. One of our strategies to recruit this talent is the establishment of multiple design center locations. As a result, we have design centers throughout the world.

Circuit design engineers, layout engineers, product and test engineers, application engineers, and field application engineers are our most valuable employees. Together they perform the critical tasks of design and layout of ICs, turning these circuits into silicon devices, and conferring with customers about designing these devices into their applications. The majority of our engineers fit into one of these categories. Most of these engineers have many years of experience in the design, development and layout of circuits targeted for use in protection, advanced communications, power management and high-reliability, multimedia and data communications, and wireless and sensing applications. We also employ a number of software engineers and systems engineers that specialize in the development of software and systems architecture, who enable us to develop systems oriented products in select markets.

In fiscal year 2017 , we incurred $102.5 million of product development and engineering expense. This represents 19% of net sales. Product development and engineering costs were $113.7 million or 23% of net sales and $119.4 million or 21% of net sales in fiscal years 2016 and 2015 , respectively. The expenses in fiscal year 2015 included $6.6 million of impairment charges relating to our decision to reduce investments in the optical long-haul market.

We occasionally enter into agreements with customers that allow us to recover certain costs associated with product design and engineering services. Any recovery for these services is recognized during the period in which services are performed, which

historically lags behind the period in which we recognize expense. This difference in recognition timing can create volatility in our reported development and engineering expenses.

Sales and Marketing

Net sales made directly to customers during fiscal years 2017 , 2016 and 2015 , were approximately 35% , 42% and 44% , of total net sales, respectively. The remaining 65% , 58% and 56% of net sales were made through independent distributors. The decline in direct sales in the past three years is related to substantially lower sales of our 40 Gbps and 100 Gbps long-haul transport products which were predominantly sold directly to our end-customers. Additionally, we have expanded the diversity of products sold to our Korean customers and a higher percentage of these new product sales are being made through distribution. We have direct sales personnel located throughout the United States, Europe and Asia who manage the sales activities of independent sales representative firms and independent distributors. We expense our advertising costs as they are incurred.

We operate internationally through our foreign subsidiaries. Semtech (International) AG serves the European and Asian markets from its headquarters in Rapperswil, Switzerland and through its wholly-owned subsidiaries based in the United Kingdom and Japan. Semtech (International) AG also maintains branch offices, either directly or through one of its wholly-owned subsidiaries, in multiple countries, including China, Taiwan and Korea. Semtech Canada Corporation serves the Canadian market for Gennum products, which are now part of the Signal Integrity Products Group, from its headquarters in Burlington, Ontario. Independent representatives and distributors are also used to serve customers throughout the world. Some of our distributors and sales representatives also offer products from our competitors, as is customary in the industry.

In the fourth quarter of fiscal year 2016, we entered into an agreement with STMicroelectronics International N.V. ("STMicroelectronics") to scale our LoRa wireless RF technology ("LoRa Technology") to provide customers with an additional resource for developing and deploying IoT solutions. While no revenue has been recorded as a result of this arrangement in fiscal year 2017, we believe that this type of agreement will provide a meaningful enhancement in our approach to supporting our customers in the future.

(1)	Premier is a distributor with a concentration of sales to Samsung. The above percentages represent our estimate of the sales activity related to Samsung that is passing through this distributor.

Concentration of Accounts Receivable - Significant Customers

The Company did not have any customers that accounted for at least 10% of total net receivables as of January 29, 2017 or January 31, 2016 .

Our backlog of orders as of the end of fiscal years 2017 , 2016 and 2015 was approximately $112.4 million , $84.2 million and $72.7 million , respectivel y. The majority of our backlog is typically requested for delivery within six months. In markets where the end system life cycles are relatively short, customers typically request delivery in four to eight weeks. A backlog analysis at any given time gives little indication of our future business except on a short-term basis, principally within the next 45 days. We do not have any significant backlog with deliveries beyond 18 months.

Manufacturing Capabilities

Our strategy is to outsource most of our manufacturing functions to third-party foundries and assembly and test contractors. The third-party foundries fabricate silicon wafers, and the assembly and test contractors package and test our products. We believe this outsourcing permits us to take advantage of the best available technology, leverage the capital investment of others, and reduce our operating costs associated with manufacturing assets.

We perform a limited amount of internal probe and final test activities at our facilities in Camarillo, Irvine, and San Diego in California; Neuchâtel in Switzerland; and Reynosa in Mexico. These activities accommodate situations in which tight coupling with product design is desirable or where there are unique requirements. Our packaged discrete rectifier products are packaged and tested in-house in Reynosa, Mexico. Almost all of our other products are packaged and tested by outside subcontractors.

In keeping with our mostly "fabless" business model, we have no wafer fabrication facilities except for our operation in Reynosa, Mexico. For fiscal year 2017 , the Reynosa facility provided almost all of the silicon for our packaged discrete rectifier products, which were approximately 3% of our end product net sales. The remaining 97% of our end products were supported with finished silicon wafers purchased from third-party wafer foundries in China, Taiwan, the U.S. and Israel. We anticipate that substantially all the silicon wafers we require will come from third-party foundries in fiscal year 2018 .

Despite our use of third-party wafer foundries for sourcing a majority of our silicon needs, we do maintain internal process development capabilities. Our process engineers work closely with our third-party foundries on the improvement and development of process capabilities. In fiscal year 2017 , we purchased the vast majority of our wafers from approximately four

different third-party wafer foundries and used various manufacturing processes, including Bipolar, CMOS, RF-CMOS and Silicon Germanium ("SiGe") BiCMOS processes.

While we do have some redundancy of fabrication processes by using multiple third-party foundries, any interruption of supply by one or more of these foundries could materially impact us. As a result, we maintain some amount of business interruption insurance in part to help reduce the financial risk associated with a wafer supply interruption, but we are not fully insured against this risk.

Although our products are made from basic materials (principally silicon, metals and plastics), all of which are available from a number of suppliers, capacity at wafer foundries sometimes becomes constrained. The limited availability of certain materials, such as silicon wafer substrates, may impact our suppliers’ ability to meet our demand needs or impact the price we are charged. The prices of certain other basic materials, such as metals, gases and chemicals used in the production of ICs can exhibit price volatility depending on the changes in demand for these basic commodities. In most cases we do not procure these materials ourselves, but we are nevertheless reliant on these materials for producing our products because our third-party foundry and package and test subcontractors must procure them. To help minimize risks associated with constrained capacity, we use multiple foundries and have taken other steps to prevent supply interruptions at certain foundries and subcontractors.

In fiscal years 2017 , 2016 , and 2015 , a Chinese foundry provided 25% , 28% and 37% of our total silicon requirements in terms of cost of wafers purchased, respectively. We have consigned certain equipment to this foundry to support our specialized processes run at the foundry and to ensure a specified level of capacity over the next few years. While the provision of these assets to the wafer foundry may be factored into certain pricing arrangements with the foundry, the impact of any pricing adjustments is insignificant and does not impact our margin trends.

We use third-party subcontractors to perform almost all of our assembly and test operations. A majority of our assembly and test activity is conducted by third-party subcontractors based in China, Malaysia, Taiwan, Thailand, Korea and the Philippines. We have operations offices located in the Philippines, Malaysia and China that support and coordinate some of the worldwide shipment of products. We have installed our own test equipment at some of our packaging and testing subcontractors in order to ensure a certain level of capacity, assuming the subcontractor has ample employees to operate the equipment.

Our arrangements with both third-party wafer foundries and package and test subcontractors are designed to provide some assurance of capacity but are not expected to assure access to all the manufacturing capacity we may need in the future.

Competition

The analog and mixed-signal semiconductor industry is highly competitive, and we expect competitive pressures to continue. Our ability to compete effectively and to expand our business will depend on our ability to continue to recruit and retain key engineering talent, our ability to execute on new product developments, and our ability to persuade customers to design these new products into their applications.

Our industry is characterized by decreasing unit selling prices over the life of a product as the volumes typically increase. However, price decreases can sometimes be quite rapid and faster than the rate of increase of the associated product volumes. We believe we compete effectively based upon our ability to capitalize on efficiencies and economies of scale in production and sales, and our ability to maintain or improve our productivity and product yields to reduce manufacturing costs.

We are in direct and active competition, with respect to one or more of our product lines, with numerous manufacturers of varying size, technical capability and financial strength. A number of these competitors are dependent on semiconductor products as their principal source of income, and some are much larger and better resourced than we are. The number of competitors has grown due to expansion of the market segments in which we participate. Additionally, there has been a trend toward consolidation in our industry as companies attempt to strengthen or hold their market positions in an evolving industry. Such consolidations may make it more difficult for us to compete effectively, including on the basis of price, sales and marketing programs, channel coverage, technology or product functionality.

We consider our primary competitors with respect to our Protection Products to include STMicroelectronics, NXP Semiconductors N.V., ON Semiconductor Corporation and Infineon Technologies AG. Our primary competitors with respect to our Signal Integrity Products are Texas Instruments Incorporated, Maxim Integrated Products, Inc., MACOM Technology Solutions Holdings, Inc., Inphi Corporation, Broadcom Limited and our customers' own internal solutions. With respect to our Power and High-Reliability products, we consider our primary competitors to include Texas Instruments Incorporated, Maxim Integrated Products Inc., Microsemi Corporation and Monolithic Power Systems. Our primary competitors with respect to our Wireless and Sensing products include Silicon Laboratories, Texas Instruments Incorporated, Analog Devices Inc. and Cypress Semiconductor Corp.

Intellectual Property and Licenses

We have been gra nted 181 U.S. patents and 61 fore ign patents and have numerous patent applications pending with respect to our products and to technologies associated with our business. The expiration dates of issued patents range from 2018 to 2035. Although we consider patents to be helpful in maintaining a competitive advantage, we do not believe they create definitive competitive barriers to entry. There can be no assurance that our patent applications will lead to issued patents, that others will not develop or patent similar or superior products or technologies, or that our patents will not be challenged, invalidated, or circumvented by others. We have no revenue from patents that expire in calendar yea r 2 017 and no significant revenue associated with patents that expir e in 2018 or 2019.

We have registered many of our trademarks in the U.S. and in various foreign jurisdictions. Registration generally provides rights in addition to basic trademark protections and is typically renewable upon proof of continued use. We have registered, or are in the process of registering, our SEMTECH trademark in many jurisdictions. In one location use of this trademark is prohibited, but we are permitted to use our Semtech International trade name. This restriction has not had a material impact on our business to date and we do not anticipate it will have a material impact in the future.

We also have registered certain materials in which we have copyright ownership, which provides additional protection for this intellectual property.

Employees

As of January 29, 2017 , we had 1,292 full-time employees. There were 490 employees in research and development, 250 in sales, marketing and field services, and 190 in general, administrative and finance. The remaining employees support operational activities, including product and test engineering, assembly, manufacturing, distribution and quality functions.

We have not had a work stoppage in the last decade and the only unionized employees are approximately 202 Mexican nationals who work at our manufacturing facility in Reynosa, Mexico. Our employee relations during the last fiscal year have been, and remain, satisfactory.

We adjust our workforce from time to time to meet the changing needs of our business. Competition for key design engineering talent globally is significant.

Government Regulations and Environmental Matters

We are required to comply, and it is our policy to comply, with numerous government regulations that are normal and customary to businesses in our industry and that operate in our markets and operating locations.

Our sales that serve the military and aerospace markets primarily consist of our High-Reliability products that have been qualified to be sold in these markets by the U.S. Department of Defense ("DOD"). In order to maintain these qualifications, we must comply with certain specifications promulgated by the DOD. As part of maintaining these qualifications, we are routinely audited by the DOD. Based on current specifications, we believe we can maintain our qualifications for the foreseeable future. However, these specifications could be modified by the DOD in the future or we could become subject to other government requirements, which could make the manufacturing of these products more difficult and thus could adversely impact our profitability in the Power and High-Reliability product group. In fiscal year 2017 , our sales that serve military and aerospace markets made up 3% of net sales. The U.S. State Department has determined that a small number of special assemblies from the Power and High-Reliability product line are subject to the International Traffic in Arms Regulations ("ITAR"). We have a Technical Assistance Agreement in place that permits us to assemble certain of these products in Mexico. International shipments of products subject to ITAR require a State Department license.

For further discussion related to environment matters, see Note 14 to our Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

Item 1A.	Risk Factors

You should carefully consider and evaluate all of the information in this Annual Report on Form 10-K, including the risk factors listed below. The risks described below are not the only ones facing our Company. Additional risks not now known to us or that we currently deem immaterial may also impair our business operations. If any of these risks actually occur, our business could be materially harmed. If our business is harmed, the trading price of our common stock could decline.

As discussed earlier in "Special Note Regarding Forward-Looking and Cautionary Statements," this Annual Report on Form 10-K contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of such risks and uncertainties and certain factors including the risks faced by us described below and elsewhere in this Annual Report on Form 10-K, including, without limitation, information under the section "Management's Discussion and Analysis of Financial Condition and Results of Operations" and additional factors that accompany the related forward-looking statements in this Annual Report on Form 10-K, in the Company's other filings with the SEC, and in material incorporated herein and therein by reference. In light of the significant risks and uncertainties inherent in the forward-looking information included herein that may cause actual performance and results to differ materially from those predicted, any such forward-looking information should not be regarded as representations or guarantees by the Company of future performance or results, or that its objectives or plans will be achieved or that any of its operating expectations or financial forecasts will be realized. Reported results should not be considered an indication of future performance. Investors are cautioned not to place undue reliance on any forward-looking information contained herein, which reflect management's analysis only as of the date hereof. Except as required by law, the Company assumes no obligation to publicly release the results of any update or revision to any forward-looking statements that may be made to reflect new information, events or circumstances after the date hereof or to reflect the occurrence of unanticipated or future events, or otherwise.

Risks Relating to General Business Conditions

Our future results may fluctuate, fail to match past performance or fail to meet expectations.

Our results may fluctuate in the future, may fail to match our past performance or fail to meet our expectations and the expectations of analysts and investors. Our results and related ratios, such as gross margin, operating income percentage and effective tax rate may fluctuate as a result of:


•	general economic conditions in the countries where we sell our products;


•	seasonality and variability in the computer market and our other end-markets;


•	the timing of new product introductions by us, our customers and our competitors;


•	product obsolescence;


•	the scheduling, rescheduling or cancellation of orders by our customers;


•	the cyclical nature of demand for our customers’ products;


•	our ability to predict and meet evolving industry standards and consumer preferences;


•	our ability to develop new process technologies and achieve volume production;


•	our ability to integrate and realize synergies from recent acquisitions;


•	changes in manufacturing yields;


•	capacity utilization;


•	product mix and pricing;


•	movements in exchange rates, interest rates or tax rates;


•	the availability of adequate supply commitments from our outside suppliers;


•	the manufacturing and delivery capabilities of our subcontractors; and


•	litigation and regulatory matters.

As a result of these factors, our past financial results are not necessarily indicative of our future results.

Downturns in the business cycle could adversely affect our revenues and profitability.

The semiconductor industry is highly cyclical and has experienced significant downturns, which are characterized by reduced product demand, production overcapacity, increased levels of inventory, industry-wide fluctuations in the demand for semiconductors and the significant erosion of average selling prices. The cyclical nature of the semiconductor industry may cause us to experience substantial period-to-period fluctuations in our operating results. The growth rate of the global economy is one of the factors affecting demand for semiconductor components. Many factors could adversely affect regional or global economic growth including increased price inflation for goods, services or materials, rising interest rates in the U.S. and the rest of the world, or tight credit markets. In addition, economic slowdowns may also affect our customers’ ability to pay for our products. Accordingly, economic slowdowns may harm our business.

Current global economic conditions and the potential changes in global economic policy, including the North American Free Trade Agreement, or NAFTA, and the Trans-Pacific Partnership, or TPP, could reduce demand for our products.

Uncertainty about global economic conditions can pose a risk to the overall economy by causing fluctuations to and reductions in consumer and commercial spending. Demand for our products could be different from our expectations due to many factors including changes in business and economic conditions, conditions in the credit market that affect consumer confidence, customer acceptance of our products, changes in customer order patterns, including order cancellations, and changes in the level of inventory held by vendors. In particular, in fiscal year 2017 , sales to customers in China comprised 48% of our net sales. The recent economic slowdown in China could adversely affect our sales to customers in China and consequently, our business, operating results and financial condition.

Further, changes in U.S. and global social, political, regulatory and economic conditions or in laws and policies governing foreign trade, manufacturing, development and investment could adversely affect our business. For instance, significant changes to foreign trade policy, including NAFTA and TPP and potential increases on tariffs of goods imported into the U.S. could have a significant impact on the demand for end products that incorporate our components, which may reduce our sales.

Business interruptions could harm our business.

Our corporate headquarters, a portion of our assembly and research and development activities and certain other critical business operations are located near major earthquake fault lines. We do not maintain earthquake insurance and our business could be harmed in the event of a major earthquake. We generally do not maintain flood coverage, including for our Asian locations where certain of our operations support and sales offices are located. Such flood coverage has become very expensive; as a result we have elected not to purchase this coverage. If one of these locations were to experience a major flood, our business may be harmed.

Our business could be harmed if natural disasters interfere with production of wafers by our suppliers, with assembly and testing of products by our subcontractors, or with our distribution network. We maintain some business interruption insurance to help reduce the effect of such business interruptions, but we are not fully insured against such risks. Likewise, our business could be adversely impacted if a natural disaster were to shut down or significantly curtail production by one or more of our end customers. Any such loss of revenue due to a slowdown or cessation of end customer demand is uninsured.

When natural disasters such as an earthquake or other causes result in wide-spread destruction, the impact on our business may not be readily apparent. This is especially true when trying to assess the impact of the disaster on our end customers, who themselves may not fully understand the impact of the event on their businesses. The full extent and scope of natural disaster impacts, both in terms of direct impact on us and our supply chain, as well as on our end customers (to include their own supply chain issues as well as end-market issues), may not be known for a considerable period of time following the disaster. When any such natural disaster occurs, there can be no assurance that our operating results may not be materially affected as a result of the impact of the disaster on us or on our end customers.

We rely on third party freight firms for nearly all of our shipments from vendors to assembly and test sites, primarily in Asia, and for shipments of our final product to customers. This includes ground and air transportation. Any significant disruption of such freight business globally or in certain parts of the world, particularly where our operations are concentrated, could materially and adversely affect our ability to generate revenues. Business interruption insurance may not provide enough protection to compensate us for losses that may occur. Accordingly, any of these disruptions could significantly harm our business.

Terrorist attacks, wars and other acts of violence, or any other national or international crisis, calamity or emergency, may result in interruption to the business activities of many entities, business losses and overall disruption of the economy at many levels. These events may directly impact our physical facilities or those of our customers and suppliers. Additionally, these events or armed conflicts may cause some of our customers or potential customers to reduce the level of expenditures on their services

and products that ultimately may reduce our revenue. The consequences of these reductions are unpredictable, and we may not be able to foresee events that could have an adverse effect on our business. For example, as a result of these events, insurance premiums for businesses may increase and the scope of coverage may be decreased. Consequently, we may not be able to obtain adequate insurance coverage for our business and properties. To the extent that these disruptions result in delays or cancellations of customer orders, a general decrease in corporate spending, or our inability to effectively market our services and products, our business and operating results could be harmed.

We operate a manufacturing facility in Reynosa, Mexico. Historically, certain regions in Mexico have experienced high levels of violence. Any significant disruption of our operations at this facility could materially affect our ability to generate revenues for certain products within our High-Reliability product line. Some of the products that we produce at this facility require certification by the Defense Contract Audit Agency ("DCAA"). Failure to secure or maintain the required certification, either directly through the DCAA or through a qualifying third party would materially affect our authorization to manufacture applicable products at this facility, and our revenue for certain products within our Power and High-Reliability product line could materially decline. An audit was performed in May 2012 by the Defense Logistics Agency ("DLA") Land and Maritime office, which is the DOD agency having oversight responsibility for applicable products manufactured in this facility. We received a letter of certification allowing us to continue producing High-Reliability products in 2013. The applicable certification will maintain our listing on the DOD Qualified Parts List as a MIL-PRF-19500 Semiconductor Manufacturer of JAN, JANTX, JANTXV and JANS quality level components. The DLA has indicated, barring any unforeseen circumstances, that our next surveillance audit may occur in late 2017 .

A large percentage of our sales are to customers located in Asia and a large percentage of our products are manufactured in Asia. One of our largest customer bases in Asia is located in Taiwan. An outbreak of SARS or other health related issues, such as an avian influenza (bird flu) pandemic, could have a negative impact on consumer demand, on travel needed to secure new business or manage our operations, on transportation of our products from our suppliers or to our customers, or on workers needed to sell or manufacture our products or our customers’ products.

Risks Relating to Production Operations

We obtain many essential components and materials and certain critical manufacturing services from a limited number of suppliers and subcontractors, most of which are foreign-based entities.

Our reliance on a limited number of subcontractors and suppliers for wafers, packaging, testing and certain other processes involves several risks, including potential inability to obtain an adequate supply of required components and reduced control over the price, timely delivery, reliability and quality of components. These risks are attributable to several factors, including limitations on resources, labor problems, equipment failures or the occurrence of natural disasters. The good working relationships we have established with our suppliers and subcontractors could be disrupted, and our supply chain could suffer, if a supplier or subcontractor were to experience a change in control. There can be no assurance that problems will not occur in the future with suppliers or subcontractors. Disruption or termination of our supply sources or subcontractors could significantly delay our shipments and harm our business. Delays could also damage relationships with current and prospective customers. Any prolonged inability to obtain timely deliveries or quality manufacturing or any other circumstances that would require us to seek alternative sources of supply or to manufacture or package certain components internally could limit our growth and harm our business.

We are subject to risk from fluctuating market prices of certain commodity raw materials, particularly gold, that are incorporated into our end products or used by our suppliers to process our end products. Increased commodity prices are passed on to us in the form of higher prices from our suppliers, either in the form of general price increases or commodity surcharges. Although we generally deal with our suppliers on a purchase order basis rather than on a long-term contract basis, we generally attempt to obtain firm pricing for volumes consistent with planned production. Our gross margins may decline if we are not able to increase selling prices of our products or obtain manufacturing efficiencies to offset the increased cost. We do not enter into formal hedging arrangements to mitigate against commodity risk.

Most of our third-party subcontractors and suppliers, including foundries that supply silicon wafers, are located in foreign countries, including China, Taiwan and Israel. For fiscal year 2017 , approximately 25% of our silicon in terms of cost of wafers, was supplied by a third-party foundry in China, and this percentage could be even higher in future periods. For fiscal years 2016 and 2015 , approximately 28% and 37% of our silicon in terms of cost of wafers was supplied by this third-party foundry in China, respectively. While our utilization of multiple third-party foundries does create some redundancy of fabrication processes, any interruption of supply by one or more of these foundries could materially impact us. We maintain some amount of business interruption insurance to help reduce the risk of wafer supply interruption, but we are not fully insured against such risk.

A majority of our package and test operations are performed by third-party contractors based in Malaysia, Korea, Taiwan, Thailand, the Philippines and China. Our international business activities, in general, are subject to a variety of potential risks resulting from political and economic uncertainties. Any political turmoil or trade restrictions in these countries, particularly China, could limit our ability to obtain goods and services from these suppliers and subcontractors. The effect of an economic crisis or political turmoil on our suppliers located in these countries may impact our ability to meet the demands of our customers. If we find it necessary to transition the goods and services received from our existing suppliers or subcontractors to other firms, we would likely experience an increase in production costs and a delay in production associated with such a transition, both of which could have a significant negative effect on our operating results, as these risks are substantially uninsured.

Our products may be found to be defective, product liability claims may be asserted against us and we may not have sufficient liability insurance.

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 be non-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). Since a defect or failure in our product could give rise to failures in the goods that incorporate them (and consequential claims for 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.

Our general warranty policy provides for repair or replacement of defective parts. In some cases, a refund of the purchase price is offered. In certain instances, we have agreed to other warranty terms, including some indemnification provisions, which could prove to be significantly more costly than repair, replacement or refund. We attempt to limit our liability through our standard terms and conditions and negotiation of sale and other customer contracts, but there is no assurance that such limitations will be accepted or effective. While we maintain some insurance for such events, 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, would have adverse effects (that could be material) on our business, operating results and financial condition. Additionally, in the event that our products fail to perform as expected, our reputation may be damaged, which could make it more difficult for us to sell our products to existing and prospective customers and could adversely affect our business, operating results and financial condition.

Obsolete inventories as a result of changes in demand for our products and change in life cycles of our products could adversely affect our business, operating results and financial condition.

The life cycles of some of our products depend heavily upon the life cycles of the end-products into which our products are designed. End-market products with short life cycles require us to manage closely our production and inventory levels. Inventory may also become obsolete because of adverse changes in end-market demand. We may in the future be adversely affected by obsolete or excess inventories, which may result from unanticipated changes in the estimated total demand for our products or the estimated life cycles of the end-products into which our products are designed. In addition, some customers restrict how far back the date of manufacture for our products can be and certain customers may stop ordering products from us and go out of business due to adverse economic conditions; therefore, some of our product inventory may become obsolete and, thus, adversely affect our business, operating results and financial condition.

Risks Relating to Research and Development, Engineering, Intellectual Property and New Technologies

We may be unsuccessful in developing and selling new products, which is central to our objective of maintaining and expanding our business.

We operate in a dynamic environment characterized by price erosion, rapid technological change, and design and other technological obsolescence. Our competitiveness and future success depend on our ability to predict and adapt to these changes in a timely and cost-effective manner by designing, developing, manufacturing, marketing and providing support for our own new products and technologies.

A failure to achieve design wins, to introduce these new products in a timely manner, or to achieve market acceptance for these products on commercially reasonable terms could harm our business.

The introduction of new products presents significant business challenges because product development commitments and expenditures must be made well in advance of product sales. The success of a new product depends on accurate forecasts of

long-term market demand and future technological developments, as well as on a variety of specific implementation factors, including:


•	timely and efficient completion of technology, product and process design and development;


•	timely and efficient implementation of manufacturing, assembly, and test processes;


•	the ability to secure and effectively utilize fabrication capacity in different geometries;


•	product performance;


•	product quality and reliability; and


•	effective marketing, sales and service

Even if we are able to develop products and achieve design wins, the design wins may never generate revenues if end-customer projects are unsuccessful in the marketplace or the end-customer terminates the project, which may occur for a variety of reasons. Mergers and consolidations among customers may lead to termination of certain projects before the associated design win generates revenue. If design wins do generate revenue, the time lag between the design win and meaningful revenue can be uncertain and could be significant. If we fail to develop products with required features or performance standards or experience even a short delay in bringing a new product to market, or if our customers fail to achieve market acceptance of their products, our business, financial condition and operating results could be materially and adversely impacted.

Our customers require our products to undergo a lengthy and expensive qualification process without any assurance of product sales.

Prior to purchasing our products, our customers require that our products undergo an extensive qualification process, which involves testing of the products in the customer's system as well as rigorous reliability testing. This qualification process may continue for six months or longer. However, qualification of a product by a customer does not ensure any sales of the product to that customer. Even after successful qualification and sales of a product to a customer, a subsequent revision to the product or software, changes in the manufacturing process or the selection of a new supplier by us may require a new qualification process, which may result in delays and in us holding excess or obsolete inventory. After our products are qualified, it can take an additional six months or more before the customer commences volume production of components or devices that incorporate our products. Despite these uncertainties, we devote substantial resources, including design, engineering, sales, marketing and management efforts, toward qualifying our products with customers in anticipation of sales. If we are unsuccessful or delayed in qualifying any of our products with a customer, such failure or delay would preclude or delay sales of such product to the customer, which may impede our growth and cause our business to suffer.

Our products may fail to meet new industry standards or requirements and the efforts to meet such industry standards or requirements could be costly .

Many of our products are based on industry standards that are continually evolving. Our ability to compete in the future will depend in part on our ability to anticipate, identify and ensure compatibility or compliance with these evolving industry standards. The emergence of new industry standards could render our products incompatible with products developed by our customers and potential customers. As a result, we could be required to invest significant time and effort and to incur significant expense to redesign our products to ensure compliance with relevant standards. If our products are not in compliance with prevailing industry standards or requirements, we could miss opportunities to achieve crucial design wins which in turn could have a material adverse effect on our business, operating results and financial conditions.

We may be unable to adequately protect our intellectual property rights.

We pursue patents for some of our new products and unique technologies, but we rely primarily on trade secret protections through a combination of nondisclosure agreements and other contractual provisions, as well as our employees’ commitment to confidentiality and loyalty, to protect our know-how and processes. We intend to continue protecting our proprietary technology, including through trademark and copyright registrations and patents. Despite this intention, we may not be successful in achieving adequate protection. Our failure to adequately protect our material know-how and processes could harm our business. There can be no assurance that the steps we take will be adequate to protect our proprietary rights, that our patent applications will lead to issued patents, that others will not develop or patent similar or superior products or technologies, or that our patents will not be challenged, invalidated, or circumvented by others. Furthermore, the laws of the countries in which our products are or may be developed, manufactured or sold may not protect our products and intellectual property rights to the same extent as laws in the U.S.

We may suffer losses and business interruption if our products infringe the intellectual property rights of others.

The semiconductor industry is characterized by frequent claims of infringement and litigation regarding patent and other intellectual property rights. Due to the number of competitors, intellectual property infringement is an ongoing risk since other companies in our industry could have intellectual property rights that may not be identifiable when we initiate development efforts. Litigation may be necessary to enforce our intellectual property rights and we may have to defend ourselves against infringement claims. Any such litigation could be very costly and may divert our management’s resources. If one of our products is found to infringe on a third party’s rights, we may have liability for past infringement and may need to seek a license to use such intellectual property going forward. If a license is not available or if we are unable to obtain a license on terms acceptable to us, we would either have to change our product so that it does not infringe or stop making the product.

We must commit resources to product production prior to receipt of purchase commitments and could lose some or all of the associated investment.

Sales are made primarily on a current delivery basis, pursuant to purchase orders that may be revised or cancelled by our customers without penalty, rather than pursuant to long-term contracts. Some contracts require that we maintain inventories of certain products at levels above the anticipated needs of our customers. As a result, we must commit resources to the production of products without binding purchase commitments from customers. Our inability to sell products after we devote significant resources to them could harm our business.

Risks Relating to International Operations

We sell and trade with foreign customers, which subjects our business to increased risks.

Sales to foreign customers accounted for approximately 91% of net sales in the fiscal year ended January 29, 2017 . Sales to our customers located in China (including Hong Kong) and South Korea constituted 48% and 7%, respectively, of net sales for fiscal year 2017 . International sales are subject to certain risks, including unexpected changes in regulatory requirements, tariffs and other barriers, political and economic instability, difficulties in accounts receivable collection, difficulties in managing distributors and representatives, difficulties in staffing and managing foreign subsidiary and branch operations and potentially adverse tax consequences. These factors may harm our business. Our use of the Semtech name may be prohibited or restricted in some countries, which may negatively impact our sales efforts. In addition, substantially all of our foreign sales are denominated in U.S. dollars and currency exchange fluctuations in countries where we do business could harm us by resulting in pricing that is not competitive with prices denominated in local currencies.

Our foreign currency exposures may change over time as the level of activity in foreign markets grows and could have an adverse impact upon financial results.

As a global enterprise, we face exposure to adverse movements in foreign currency exchange rates. Certain of our assets, including certain bank accounts, exist in non-U.S. dollar-denominated currencies, which are sensitive to foreign currency exchange rate fluctuations. The non-U.S. dollar-denominated currencies are principally the Swiss Franc, Euro, Canadian dollars, Mexican Peso, Japanese Yen and British Pound Sterling. We also have a significant number of employees that are paid in foreign currency, the largest groups being United Kingdom-based employees who are paid in British Pound Sterling, Swiss-based employees who are paid in Swiss Francs, Canada-based employees who are paid in Canadian dollars, and Mexican nationals who are paid in Mexican Pesos.

Although the value of the U.S. dollar has strengthened recently, if the value of the U.S. dollar weakens relative to these specific currencies, as it has done in recent years, the cost of doing business in terms of U.S. dollars rises. With the growth of our international business, our foreign currency exposures may grow and under certain circumstances, could harm our business.

As a means of managing our foreign exchange exposure, we routinely convert U.S. dollars into foreign currency in advance of the expected payment. We regularly assess whether or not to hedge foreign exchange exposure. Any future use of forward contracts to hedge foreign exchange exposure may be required to be marked-to-market each quarter and can create volatility in net income not directly tied to our operating results.

We may be subject to increased tax liabilities and an increased effective tax rate if we need to repatriate funds held by our foreign subsidiaries.

As of January 29, 2017 , our foreign subsidiaries held approximately $224.6 million of cash, cash equivalents, and short-term investments and $603.0 million of unremitted earnings for which no Federal or State taxes have been provided. If we needed these funds for investment in our domestic operations, any repatriation, such as that which occurred in fiscal year 2010 to partially fund the acquisition of SMI, could result in increased tax liabilities and a higher effective tax rate.

We are subject to export restrictions and laws affecting trade and investments.

As a global company headquartered in the U.S., we are subject to U.S. laws and regulations that limit and restrict the export of some of our products and services and may restrict our transactions with certain customers, business partners and other persons, including, in certain cases, dealings with or between our employees and subsidiaries. In certain circumstances, export control and economic sanctions regulations may prohibit the export of certain products, services and technologies, and in other circumstances we may be required to obtain an export license before exporting the controlled item. Compliance with these laws has not significantly limited our operations or our sales in the recent past, but could significantly limit them in the future. We maintain an export compliance program but there are risks that the compliance controls could be circumvented, exposing us to legal liabilities. We must also comply with export restrictions and laws imposed by other countries affecting trade and investments. Although these restrictions and laws have not significantly restricted our operations in the recent past, there is a risk that they could do so in the future.

For example, on March 8, 2016, the U.S. Department of Commerce published a final rule in the Federal Register that amended the Export Administration Regulations by adding ZTE Corporation ("ZTE") and three of its affiliates to the “Entity List” for actions contrary to the national security and foreign policy interests of the U.S. This rule imposed new export licensing requirements on exports, reexports, and in-country transfers of all U.S.-regulated products, software and technology to the designated ZTE entities, which had the practical effect of preventing us from making any sales to ZTE. On March 24, 2016, the U.S. Department of Commerce issued a temporary general license suspending the enhanced export licensing requirements for ZTE and one of its designated affiliates through June 30, 2016, thereby enabling us to resume sales to ZTE. The temporary license has since been extended to March 29, 2017.

On March 7, 2017, ZTE agreed with the U.S. Department of Justice, the U.S. Department of the Treasury’s Office of Foreign Assets Control and the U.S. Department of Commerce’s Bureau of Industry and Security, to enter a guilty plea and pay a combined penalty of up to $1.19 billion to settle civil and criminal allegations against ZTE. As a part of the settlement, the Bureau of Industry and Security agreed to recommend that ZTE be removed from the Entity List, conditioned on court approval of the plea agreement and entry of the plea and approval of the settlement by the Assistant Secretary of Commerce for Export Enforcement and issuance of a corresponding Order.

This or future regulatory activity may materially interfere with our ability to make sales to ZTE or other customers. In addition, our association with ZTE could subject us to actual or perceived reputational harm among current or prospective investors, suppliers or customers, customers of our customers, other parties doing business with us, or the general public. Any such reputational harm could result in the loss of investors, suppliers or customers, which could harm our business, financial condition, operating results or prospects.

Risks Relating to Sales, Marketing and Competition

We compete against larger, more established entities and our market share may be reduced if we are unable to respond to our competitors effectively.

The semiconductor industry is intensely competitive and is characterized by price erosion, rapid technological change, and design and other technological obsolescence. We compete with domestic and international semiconductor companies, many of which have substantially greater financial and other resources with which to pursue engineering, manufacturing, marketing and distribution of their products. We consider our primary competitors with respect to our Protection Products to include STMicroelectronics, NXP Semiconductors N.V., ON Semiconductor Corporation and Infineon Technologies AG. Our primary competitors with respect to our Signal Integrity products are Texas Instruments Incorporated, Maxim Integrated Products, Inc., MACOM Technology Solutions Holdings, Inc., Inphi Corporation, Broadcom Limited, Applied Micro Circuits Corporation and our customers' own internal solutions. With respect to our Power and High-Reliability products, we consider our primary competitors to include Texas Instruments Corporation, Maxim Integrated Products Inc., Microsemi Corporation and Monolithic Power Systems. Our primary competitors with respect to our Wireless and Sensing products include Silicon Laboratories, Texas Instruments Incorporated, Atmel Corporation, Analog Devices Inc. and Cypress Semiconductor Corp.

We expect continued competition from existing competitors as well as competition from new entrants in the semiconductor market. Our ability to compete successfully in the rapidly evolving area of integrated circuit technology depends on several factors, including:


•	success in designing and manufacturing new products that implement new technologies;


•	protection of our processes, trade secrets and know-how;


•	maintaining high product quality and reliability;


•	pricing policies of our competitors;


•	performance of competitors’ products;


•	ability to deliver in large volume on a timely basis;


•	marketing, manufacturing and distribution capability; and


•	financial strength.

To the extent that our products achieve market success, competitors typically seek to offer competitive products or lower prices; if they are successful, they could harm our business.

Industry consolidation may lead to increased competition and may harm our operating results.

There has been a trend toward industry consolidation in our industry as companies attempt to strengthen or hold their market positions in an evolving industry and as companies are acquired or are unable to continue operations. Some of our competitors have made acquisitions or entered into partnerships or other strategic relationships to offer a more comprehensive solution than they individually had offered. Such consolidations or strategic partnerships may continue in the future. The companies or alliances resulting from these possible consolidations may create more compelling bundled products as well as being able to offer greater pricing flexibility, making it more difficult for us to compete effectively, including on the basis of price, sales and marketing programs, channel coverage, technology or product functionality. Continued industry consolidation may adversely impact customers' perceptions of the viability of smaller and even medium-sized semiconductor companies such as ourselves and, consequently, customers' willingness to purchase from us. We believe that industry consolidation may result in stronger competitors, with more efficient cost structures that are better able to compete as sole-source vendors for our end-customers. This could lead to more variability in our operating results and could have a material adverse effect on our business, operating results and financial condition.

We receive a significant portion of our revenues from a small number of customers and the loss of any one of these customers or failure to collect a receivable from them could adversely affect our business.

Our largest customers have varied from year to year. Historically, we have had significant customers that individually accounted for 10% or more of consolidated revenues in certain quarters or years or represented 10% or more of net accounts receivables at any given date. The table below sets forth those customers representing greater than 10% of net sales for one more of fiscal years 2017, 2016 and 2015.

Concentration of Net Sales - Significant Customers



	Fiscal Years
(percentage of net sales)	2017		2016		2015
Trend-Tek (and affiliates)	10	%	7	%	5	%
Arrow Electronics (and affiliates)	10	%	9	%	9	%
Samsung Electronics (and affiliates)	7	%	7	%	11	%
Premier (and affiliates) ⁽¹⁾	4	%	3	%	3	%


(1)	Premier is a distributor with a concentration of sales to Samsung. The above percentages represent our estimate of the sales activity related to Samsung that is passing through this distributor.

Concentration of Accounts Receivable - Significant Customers

The Company did not have any customers that accounted for at least 10% of total net receivables as of January 29, 2017 or January 31, 2016 .

Sales to our customers are generally made on open account, subject to credit limits we may impose, and the receivables are subject to the risk of being uncollectible.

The volatility of customer demand limits our ability to predict future levels of sales and profitability.

We primarily conduct our sales on a purchase order basis, rather than pursuant to long-term contracts. The loss of any significant customer, any material reduction in orders by any of our significant customers, the cancellation of a significant customer order or the cancellation or delay of a customer’s significant program or product could harm our business.

Semiconductor suppliers can rapidly increase production output in response to slight increases in demand, leading to a sudden oversupply situation and a subsequent reduction in order rates and revenues as customers adjust their inventories to account for shorter lead times. Conversely, when circumstances create longer lead times customers may orders in excess of what they need to ensure availability, then cancel orders if lead times are reduced. A rapid and sudden decline in customer demand for products or cancellation of orders can result in excess quantities of certain products relative to demand. Should this occur, our operating results may be adversely affected as a result of charges to reduce the carrying value of our inventory to the estimated demand level or market price. Our quarterly revenues are highly dependent upon turns fill orders (orders booked and shipped in the same quarter). The short-term and volatile nature of customer demand makes it extremely difficult to accurately predict near term revenues and profits.

Most of our authorized distributors, which together represent more than half of our net sales, can terminate their contract with us with little or no notice. The termination of a distributor could negatively impact our business, including net sales and accounts receivable.

In fiscal year 2017 , authorized distributors accounted for approximately 65% of our net sales. We generally do not have long-term contracts with our distributors and most can terminate their agreement with us with little or no notice. For fiscal year 2017 , our two largest distributors were based in Asia.

The termination of any of our distributor relationships could impact our net sales and limit our access to certain end-customers. It could also result in the return of excess inventory of our product held by that distributor. Since many distributors simply resell finished products, they generally operate on very thin profit margins. If a distributor were to terminate an agreement with us or go out of business, our accounts receivable from the particular distributor would be subject to significant collection risk. Our reliance on distributors also subjects us to a number of additional risks, including:


•	write-downs in inventories associated with stock rotation rights and increases in provisions for price adjustments granted to certain distributors;


•	potential reduction or discontinuation of sales of our products by distributors;


•	failure to devote resources necessary to sell our products at the prices, in the volumes and within the time frames that we expect;


•	dependence upon the continued viability and financial resources of these distributors, some of which are small organizations with limited working capital and all of which depend on general economic conditions and conditions within the semiconductor industry;


•	dependence on the timeliness and accuracy of shipment forecasts and resale reports from our distributors; and


•	management of relationships with distributors, which can deteriorate as a result of conflicts with efforts to sell directly to our end customers.

If any significant distributor becomes unable or unwilling to promote and sell our products, or if we are not able to renew our contracts with the distributors on acceptable terms, we may not be able to find a replacement distributor on reasonable terms or at all and our business could be harmed.

Risks Relating to Governmental Regulations, including Taxes, Financial Reporting Rules and Regulations, and Environmental Regulations

Failure to maintain effective internal control over financial reporting or disclosure controls and procedures could have a material adverse effect on our business and stock price.

Section 404 of the Sarbanes-Oxley Act requires an annual management assessment of the effectiveness of internal controls over financial reporting and an annual report by our independent registered public accounting firm opining on our internal controls over financial reporting. Management is similarly required to review disclosure controls, which are controls established to ensure that information required to be disclosed in SEC reports is recorded, processed, summarized and reported in a timely manner.

If we fail to maintain the adequacy of our internal controls, as such standards are modified, supplemented or amended from time to time, we may not be able to ensure that we can conclude on an ongoing basis that we have effective internal control

over financial reporting. Moreover, effective internal controls are necessary for us to produce reliable financial reports and are important to help prevent fraud. As a result, any failure to satisfy the requirements of Section 404 on a timely basis could result in the loss of investor confidence in the reliability of our consolidated financial statements, which in turn could harm our business and negatively impact the trading price of our common stock.

We are subject to government regulations and other standards that impose operational and reporting requirements.

We, our suppliers, and our customers are subject to a variety of U.S. federal, foreign, state and local governmental laws, rules and regulations, including those related to the use, storage, handling, discharge or disposal of certain toxic, volatile or otherwise hazardous chemicals and the incorporation of such substances into products available for sale. If we or our suppliers were to incur substantial additional expenses to acquire equipment or otherwise comply with environmental regulations, product costs could significantly increase, thus harming our business.

Additional laws, rules and regulations at the U.S. federal and relevant foreign levels governing data privacy protections for personal information, and corrupt practices/anti-bribery prohibitions, impact our business in terms of ongoing monitoring of compliance. Legislation and related regulations in the United Kingdom under that country’s Bribery Act could have extra-territorial application of compliance standards that may be inconsistent with comparable U.S. law, requiring us to re-evaluate and amend our compliance programs, policies and initiatives.

The SEC and NASDAQ Stock Market ("NASDAQ") have revised, and continue to revise, their regulations and listing standards. These developments have increased, and may continue to increase, our legal compliance and financial reporting costs. These developments also may make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. This, in turn, could make it more difficult for us to attract and retain qualified members of our Board of Directors, or qualified executive officers.

Failure to comply with present or future laws, rules and regulations of any kind that govern our business could result in suspension of all or a portion of production, cessation of all or a portion of operations, or the imposition of significant regulatory, administrative, civil, or criminal penalties or sanctions, any of which could harm our business.

Our failure to comply with any applicable environmental regulations could result in a range of consequences, including fines, suspension of production, excess inventory, sales limitations, and criminal and civil liabilities.

We are subject to various state, federal and international laws and regulations governing the environment, including restricting the presence of certain substances in electronic products and making producers of those products financially responsible for the collection, treatment, recycling and disposal of those products. Although our management systems are designed to maintain compliance, we cannot assure you that we have been or will be at all times in complete compliance with such laws and regulations. If we violate or fail to comply with any of them, a range of consequences could result, including fines, import/export restrictions, sales limitations, criminal and civil liabilities or other sanctions. We could also be held liable for any and all consequences arising out of exposure to hazardous materials used, stored, released, disposed of by us or located at, under or emanating from our facilities or other environmental or natural resource damage. We have incurred, and may continue to incur, liabilities under various statutes for the cleanup of pollutants at locations we have operated and at third-party disposal and recycling sites we have used. For example, during our fiscal year 2016, we recorded a total of $2.9 million for an environmental reserve associated with a cleanup and abatement order from a regulatory authority at our former facility in Newbury Park, California for groundwater contamination.

Environmental laws are complex, change frequently and have tended to become more stringent over time. For example, the European Union and China are two among a growing number of jurisdictions that have enacted in recent years restrictions on the use of lead, among other chemicals, in electronic products. These regulations affect semiconductor packaging. There is a risk that the cost, quality and manufacturing yields of lead-free products may be less favorable compared to lead-based products or that the transition to lead-free products may produce sudden changes in demand, which may result in excess inventory.

Future environmental legal requirements may become more stringent or costly and our compliance costs and potential liabilities arising from past and future releases of, or exposure to, hazardous substances may harm our business and our reputation.

"Conflict minerals" regulations may cause us to incur additional expenses, may make our supply chain more complex and may result in damage to our reputation with customers.

On August 22, 2012, under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act"), the SEC adopted requirements for companies that use certain minerals and metals, known as conflict minerals, in their

products, whether or not these products are manufactured by third parties. These metals are commonly used in electronic components and devices, including our products. These regulations require companies to investigate and disclose whether or not such minerals originate from the Democratic Republic of Congo or adjoining countries. The first such report was due on June 2, 2014. The implementation of these requirements could adversely affect the sourcing, availability and pricing of such minerals used in the manufacture of semiconductor devices. As a result, there may only be a limited pool of suppliers who provide conflict free metals, and we cannot assure you that we will be able to obtain products in sufficient quantities or at competitive prices. In addition, we could incur additional costs to the extent that we are required to make changes to products, processes, or sources of supply due to the foregoing requirements, including costs related to determining the source of any of the relevant minerals and metals used in our products. Also, since our supply chain is complex, we may face reputational challenges with our customers and other stockholders if we are unable to sufficiently verify the origins for all metals used in our products. In such event, we may also face difficulties in satisfying customers who require that all of the components of our products are certified as conflict mineral free. Our revenues and margins may be harmed if we are unable to meet this requirement at a reasonable price, or at all, or are unable to pass through any increased costs associated with meeting this requirement. To the extent that proposed conflict minerals legislation is adopted by the European Commission, these risks could increase.

Certain of our customers and suppliers require us to comply with their codes of conduct, which may include certain restrictions that may substantially increase our cost of doing business as well as have an adverse effect on our operating efficiencies, operating results and financial condition .

Certain of our customers and suppliers require us to agree to comply with their codes of conduct, which may include detailed provisions on labor, human rights, health and safety, environment, corporate ethics and management systems. Certain of these provisions are not requirements under the laws of the countries in which we operate and may be burdensome to comply with on a regular basis. Moreover, new provisions may be added or material changes may be made to any these codes of conduct, and we may have to promptly implement such new provisions or changes, which may substantially further increase the cost of our business, be burdensome to implement and adversely affect our operational efficiencies and operating results. If we violate any such codes of conduct, we may lose further business with the customer or supplier and, in addition, we may be subject to fines from the customer or supplier. While we believe that we are currently in compliance with our customers and suppliers’ codes of conduct, there can be no assurance that, from time to time, if any one of our customers and suppliers audits our compliance with such code of conduct, we would be found to be in full compliance. A loss of business from these customers or suppliers could have a material adverse effect on our business, operating results and financial condition.

Our operating results could be adversely affected as a result of changes in our effective tax rates, the adoption of new U.S. or international tax legislation or exposure to additional tax liabilities, or by material differences between our forecasted annual effective tax rates and actual tax rates.

Our future effective tax rates could be affected by changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities, or changes in applicable tax laws or their interpretation. We are also subject to the examination of our tax returns and other tax matters by the Internal Revenue Service of the U.S. ("IRS") and other tax authorities and governmental bodies. We regularly assess the likelihood of an adverse outcome resulting from these examinations to determine the adequacy of our provision for taxes. There can be no assurance as to the outcome of these examinations. If our effective tax rates were to increase, particularly in the U.S. or Switzerland, or if the ultimate determination of taxes owed is for an amount in excess of amounts previously accrued, our operating results, cash flows, and financial condition could be adversely affected.

In October 2015, the Organization for Economic Co-operation and Development, an international association of 34 countries, including the U.S., released the final reports from its Base Erosion and Profit Shifting ("BEPS") Action Plans. The BEPS recommendations covered a number of issues, including country-by-country reporting, permanent establishment rules, transfer pricing rules and tax treaties. Although the BEPS recommendations are not themselves changes in tax law, this guidance has resulted in unilateral action by several member countries and is also prompting possible amendment of other countries’ tax laws and regulations on a prospective and potentially retroactive basis. In October 2015, the European Commission concluded that certain member countries had granted unlawful rulings that artificially reduced tax burdens and has ordered the recovery of the unpaid taxes. Future tax law changes resulting from these developments may result in changes to long-standing tax principles, which could adversely affect our effective tax rate or result in higher cash tax liabilities.

In addition, due to the complexity associated with the calculation of our tax provision, we have hired independent tax advisors to assist us. Significant judgment is required in the calculation of our tax provision and the resulting tax liabilities as well as determination of our ability to realize our deferred tax assets. Our estimates of future taxable income and the regional mix of this income can change as new information becomes available. Any such changes in our estimates or assumptions can significantly impact our tax provision in a given period by, for example, requiring us to impair existing deferred tax assets.

Such required changes could result in us having to restate our consolidated financial statements. Restatements are generally costly and could adversely impact our operating results or have a negative impact on the trading price of our common stock.

We are subject to review by taxing authorities, including the Internal Revenue Service.

We are subject to review by domestic and foreign taxing authorities, including the IRS. Tax years prior to 2012 (fiscal year 2013) are generally not subject to examination by the IRS except for items with tax attributes that could impact open tax years. Changes to our tax filings could materially impact our tax liabilities and effective tax rate.

We may be subject to taxation and review of our compliance with value-added and other sales-type tax regulations in other jurisdictions which could negatively affect our operations.

As a global organization, we may be subject to a variety of transfer pricing or permanent establishment challenges by taxing authorities in various jurisdictions. If certain of our non-U.S. activities were treated as carrying on business as a permanent establishment and therefore, subject to income tax in such jurisdiction, our operating results could be materially adversely affected.

We are required to comply with rules regarding value-added taxes and other sales-type taxes in various jurisdictions. If these taxes are not properly collected and paid, our operating results could be materially adversely affected.

We have limited experience with government contracting, which entails differentiated business risks.

Although such contracts have not constituted a material portion of our revenue in the past, we may from time-to-time derive revenue from contracts and subcontracts with agencies of, or prime or secondary contractors to, the U.S. government, including U.S. military agencies. Consequently, we are subject to certain business risks that are particular to companies that contract with U.S. government agencies. These risks include the ability of the U.S. government or related contractors to unilaterally:


•	terminate contracts at its convenience;


•	terminate, modify or reduce the value of existing contracts, if budgetary constraints or needs change;


•	cancel multi-year contracts and related orders, if funds become unavailable;


•	adjust contract costs and fees on the basis of audits performed by U.S. government agencies;


•	control and potentially prohibit the export of our products;


•	require that we continue to supply products despite the expiration of a contract under certain circumstances;


•	require that we fill certain types of rated orders for the U.S. government prior to filling any orders for other customers; and


•	suspend us from receiving new contracts pending resolution of any alleged violations of procurement laws or regulations.

In addition, because we may enter into defense industry contracts with respect to products that are sold both within and outside of the U.S., we are subject to the following additional risks in connection with government contracts:


•	the need to bid on programs prior to completing the necessary design, which may result in unforeseen technological difficulties, delays and/or cost overruns;


•	the difficulty in forecasting long-term costs and schedules and the potential obsolescence of products related to long-term fixed price contracts; and


•	the need to transfer and obtain security clearances and export licenses, as appropriate.

Government investigations and inquiries from regulatory agencies could lead to enforcement actions, fines, restatement of our financial statements or other penalties and could result in litigation against us.

In the past, we have been subject to government investigations and inquiries from regulatory agencies such as the SEC and we have had to restate our historical financial statements in connection with such inquiry related to our historical stock option practices. We may be subject to government investigations and receive additional inquiries from regulatory agencies in the future, which may lead to enforcement actions, fines or other penalties.

In addition, litigation has often been brought against a company in connection with the announcement of a government investigation or inquiry from a regulatory agency. Such lawsuits could result in the diversion of management’s time and attention away from business operations, which could harm our business. In addition, the costs of defense and any damages resulting from litigation, a ruling against us, or a settlement of the litigation could adversely affect our cash flow and financial results.

If such government investigations or inquiries result in a restatement of our financial statements, this could delay the filing of our subsequent SEC reports which, in turn, might result in the delisting of our common stock from NASDAQ for failure to meet continued listing requirements.

Risks Relating to our Business Strategies, Personnel and Other Operations

The loss of any of our key personnel or the failure to attract or retain specialized technical and management personnel could impair our ability to grow our business.

Our future success depends upon our ability to attract and retain highly qualified technical, marketing and managerial personnel. We are dependent on a relatively small group of key technical personnel with analog and mixed-signal expertise. Personnel with highly skilled managerial capabilities, and analog and mixed-signal design expertise, are scarce and competition for personnel with these skills is intense. There can be no assurance that we will be able to retain key employees or that we will be successful in attracting, integrating or retaining other highly qualified personnel in the future. If we are unable to retain the services of key employees or are unsuccessful in attracting new highly qualified employees, our business could be harmed.

If our stock price declines below the exercise price of stock options held by our employees, the retention incentive aspect of the stock options is lost and there is a greater likelihood we will be unable to retain key talent.

We face risks associated with companies we have acquired in the past and may acquire in the future.

We have expanded our operations through strategic acquisitions, such as the acquisition of SMI in December 2009, Gennum in March 2012, select assets from EnVerv in January 2015, and Triune in March 2015, and we may continue to expand and diversify our operations with additional acquisitions. Acquisitions have used and could use in the future a significant portion of our available liquid assets or we could incur debt or issue equity securities to fund acquisitions. Issuance of equity securities could be dilutive to existing shareholders. Debt financing could subject us to restrictive covenants that could have an adverse effect on our business. Although we undertake detailed reviews of proposed acquisition candidates and attempt to negotiate acquisition terms favorable to us, we may encounter difficulties or incur liabilities for which we have no recourse. We cannot provide any assurance that any acquisition will have a positive impact on our future performance.

If we are unsuccessful in integrating acquired companies into our operations or if integration is more difficult than anticipated, then we may not achieve anticipated cost savings or synergies and may experience disruptions that could harm our business. Some of the risks that may affect our ability to successfully integrate acquired companies include those associated with:


•	conforming the acquired company’s standards, processes, procedures and controls with our operations;


•	coordinating new product and process development, especially with respect to highly complex technologies;


•	assuring acquired products meet our quality standards;


•	loss of key employees or customers of the acquired company;


•	hiring additional management and other critical personnel;


•	increasing the scope, geographic diversity and complexity of our operations;


•	consolidation of facilities and functions;


•	the geographic distance between the companies; and


•	disparate corporate cultures.

Acquisitions could have a negative impact on our future earnings by way of poor performance by the acquired company or, if we later conclude we are unable to use or sell an acquired product or technology, we could be required to write down the related intangible assets and goodwill.

We may be required to recognize additional impairment charges in the future which could have an adverse effect on our financial condition and operating results.

We assess our goodwill, other intangible assets and our long-lived assets on an annual basis and whenever events or changes in circumstances indicate the carrying value of our assets may not be recoverable, and as and when required by accounting principles generally accepted in the U.S. ("GAAP") to determine whether they are impaired. In fiscal year 2014, in connection with the restructuring related to the combination of our former Advanced Communications Product group, we recorded charges of approximately $150.0 million for the impairment of goodwill and certain intangible assets. Additionally, in fiscal year 2015, in connection with our strategic decision to reduce our investment in the defense and microwave communications infrastructure markets and to further reduce investment in the long-haul optical market, we recorded additional charges of approximately $14.8 million for impairment of intangible assets. Future restructuring or appraisal of our business impacting fair value of our

assets or changes in estimates of our future cash flows could affect our impairment analysis in future periods and cause us to record either an additional expense for impairment of assets previously determined to be partially impaired or record an expense for impairment of other assets. Depending on future circumstances, we may never realize the full value of intangible assets. Any future determination or impairment of a significant portion of our goodwill and other intangibles could have an adverse effect on our financial condition and operating results.

We have significant investments in entities that we do not control. Losses in the value of such investments could have an adverse effect on our financial condition or operating results.

We have significant investments in entities that we do not control, including equity and cost method investments. Our interests in such entities do not provide us with control over the business strategy, financial goals, development roadmaps or other operational aspects of these entities. We cannot provide assurance that these entities will operate in a manner that will increase or maintain the value of our investment, that our proportionate share of income or loss from these investments will continue at the current level in the future or that we will not incur losses from the holding of such investments.

To the extent that we have any interest in an entity for which we are required to consolidate, we would need to rely on those entities to timely deliver important financial information to us. In the event that the financial information is inaccurate, incomplete, or not timely, we may not be able to meet our financial reporting obligations as required by the SEC.

To the extent we create such arrangements for which we would be required to consolidate and the financial statements of such entities are not prepared by us, we will not have direct control over their financial statement preparation. As a result, we will, for our financial reporting, depend on what these entities report to us, which could result in us adding monitoring and audit processes, which could increase the difficulty of implementing and maintaining adequate controls over our financial processes and reporting in the future. This may be particularly true when such entities do not have sophisticated financial accounting processes in place, or where we are entering into new relationships at a rapid pace, straining our integration capacity. Additionally, if we do not receive the information from the variable interest entity on a timely basis, this could cause delays in our external reporting obligations as required by the SEC.

Our reported financial results may be adversely affected by new accounting pronouncements or changes in existing accounting standards and practices.

We prepare our financial statements in conformity with accounting principles generally accepted in the U.S. These accounting principles are subject to interpretation by the Financial Accounting Standards Board, SEC and various organizations formed to interpret and create appropriate accounting standards and practices. New accounting pronouncements and varying interpretations of accounting standards and practices have occurred and may occur in the future. New accounting pronouncements or a change in the interpretation of existing accounting standards or practices may have a significant effect on our reported financial results and may even affect our reporting of transactions completed before the change is announced or effective.

Our ability to generate the significant amount of cash needed to service our debt obligations or to obtain additional financing depends on many factors beyond our control.

As of January 29, 2017 , we had $243.3 million of outstanding indebtedness under our credit facilities.

Our ability to make payments on amounts borrowed under our credit facilities, and to fund our operations, will depend on our ability to generate substantial operating cash flow. Our cash flow generation will depend on our future performance, which will be subject to prevailing economic conditions and to financial, business and other factors, many of which are beyond our control.

Our business may not generate sufficient cash flow from operations and, if we cannot service our debt, we will have to take actions such as reducing or delaying capital investments, selling assets, or seeking additional equity capital. We may not be able to, if required, effect these actions on commercially reasonable terms, or at all. Because of these and other factors beyond our control, we may be unable to pay the interest on or other amounts in respect of our indebtedness.

Restrictive covenants in the credit agreement governing our senior secured first lien credit facilities may restrict our ability to pursue our business strategies.

The credit agreement governing our senior secured first lien credit facilities contain a number of restrictive covenants that impose significant operating and financial restrictions on us and may limit our ability to engage in acts that may be in our long-term best interests. The credit agreement includes covenants restricting, among other things, our and our subsidiaries’ ability to:


•	incur or guarantee additional debt or issue certain preferred stock;


•	pay dividends or make distributions on our capital stock or redeem, repurchase or retire our capital stock;


•	make certain investments and acquisitions;


•	create liens on our or our subsidiaries’ assets;


•	enter into transactions with affiliates;


•	merge or consolidate with another person or sell or otherwise dispose of substantially all of our assets;


•	make certain payments in respect of other material indebtedness;


•	alter the business that we conduct; and


•	make certain capital expenditures.

Under the credit agreement, we are required to maintain a consolidated leverage ratio and an interest expense coverage ratio. Our ability to meet such financial ratios can be affected by events beyond our control, and we cannot assure you that we will be able to meet such ratios. The credit agreement also contains various covenants and restrictions and a breach of any covenant or restriction could result in a default under our credit agreement. If any such default occurs, the lenders may elect (after the expiration of any applicable notice or grace periods) to declare all outstanding borrowings, together with accrued and unpaid interest and other amounts payable thereunder, to be immediately due and payable. Further, following an event of default under our credit facilities, the lenders will have the right to proceed against the collateral granted to them to secure that debt. If the debt under our credit facilities were to be accelerated, our assets may not be sufficient to repay in full that debt that may become due as a result of that acceleration.

We rely on certain critical information systems for the operation of our business and a disruption in our information systems, including those related to cybersecurity, could adversely affect our business operations.

We maintain and rely upon certain critical information systems for the effective operation of our business. These information systems include telecommunications, the Internet, our corporate intranet, various computer hardware and software applications, network communications, and e-mail. These information systems may be owned by us or by our outsource providers or even third parties such as vendors and contractors and may be maintained by us or by such providers or third parties. These information systems are subject to attacks, failures, and access denials from a number of potential sources including viruses, destructive or inadequate code, power failures, and physical damage to computers, hard drives, communication lines and networking equipment. To the extent that these information systems are under our control, we have implemented security procedures, such as virus protection software and emergency recovery processes, to address the outlined risks; however, security procedures for information systems cannot be guaranteed to be failsafe and our inability to use or access these information systems at critical points in time could unfavorably impact the timely and efficient operation of our business. Additionally, any compromise of our information security could result in the unauthorized publication of our confidential business or proprietary information, including potential theft of our intellectual property or trade secrets (including our proprietary technology) or the unauthorized release of customer, supplier or employee data and result in a violation of privacy or other laws, thus exposing us to litigation or damage to our reputation. To the extent that our business is interrupted or data or proprietary technology is lost, destroyed or inappropriately used or disclosed, such disruption could adversely affect our competitive position, relationship with customers, suppliers or employees or our business, financial condition and operating results. In addition, we may be required to incur significant costs to protect against or repair the damage caused by these disruptions or security breaches in the future.

The costs associated with our indemnification of certain customers, distributors, and other parties could be higher in future periods.

In the normal course of our business, we indemnify other parties, including customers, distributors, and lessors, with respect to certain matters. These obligations typically arise pursuant to contracts under which we agree to hold the other party harmless against losses arising from a breach of representations and covenants related to certain matters, such as acts or omissions of our employees, infringement of third-party intellectual property rights, and certain environmental matters. We have not incurred any significant expense as a result of agreements of this type in at least a decade, but there can be no assurances that we will not incur expense under these indemnification provisions in the future.

We have also entered into agreements with our current and former directors and certain of our current and former executives indemnifying them against certain liabilities incurred in connection with their duties. Our Certificate of Incorporation and Bylaws contain similar indemnification obligations with respect to our current and former directors and employees, as does the California Labor Code. We cannot estimate the amount of potential future payments, if any, that we might be required to make as a result of these agreements.

Our stock price could be subject to extreme price fluctuations, and stockholders could have difficulty trading shares.

Historically, the market for the stock of technology companies has been volatile, and the market price of our common stock has been and may continue to be subject to significant fluctuations. Fluctuations could be in response to items such as operating results, announcements of technological innovations, or market conditions for technology stocks in general. Additionally, the stock market in recent years has experienced extreme price and volume fluctuations that often have been unrelated to the operating performance of individual companies. These market fluctuations, as well as general economic conditions, may adversely affect the price of our common stock.

In addition, the future sale of a substantial number of shares of common stock by us or by our existing stockholders or option holders (including directors, officers, and employees, some of whom hold stock options that are approaching their expiration date) may have an adverse impact on the market price of the shares of common stock. There can be no assurance that the trading price of our common stock will remain at or near its current level.

If securities or industry analysts do not publish research or reports about our business, or if they adversely change their recommendations regarding our common stock or if our operating results do not meet their expectations, the trading price of our common stock could decline.

The market price of our common stock is influenced by the research and reports that industry or securities analysts publish about us or our business. There is no guarantee that these analysts will understand our business and results, or that their reports will be accurate or correctly predict our operating results or prospects. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause the market price of our common stock or its trading volume to decline. Moreover, if one or more of the analysts who cover our company downgrade our common stock or if our operating results or prospects do not meet their expectations, the market price of our common shares could decline significantly .

Anti-takeover provisions in our Certificate of Incorporation and Bylaws could make an acquisition of us more difficult and may prevent attempts by our stockholders to replace or remove our current management.

Certain provisions in our Certificate of Incorporation and Bylaws may delay or prevent an acquisition of us or a change in our management. These provisions include:


•	the ability of our board of directors to determine the rights, preferences and privileges of our preferred shares and to issue the preferred shares without stockholder approval;


•	advance notice requirements for election to our board of directors and for proposing matters that can be acted upon at stockholder meetings; and


•	the inability of stockholders to call a special meeting.

These provisions could make it more difficult for a third-party to acquire us, even if the third-party's offer may be considered beneficial by many stockholders. As a result, stockholders may be limited in their ability to obtain a premium for their shares.

We are subject to litigation risks which may be costly to defend and the outcome of which is uncertain and could adversely affect our business and financial condition.

All industries, including the semiconductor industry, are subject to legal claims, with and without merit, which may divert the attention of our management and our resources in general. From time to time in the ordinary course of its business, the Company is involved in various claims, litigation, and other legal actions that are normal to the nature of its business, including with respect to IP, contract, product liability, employment, and environmental matters. We believe it is unlikely that the final outcome of these legal claims will have a material adverse effect on our financial condition, operating results or cash flows. However, defense and settlement costs can be substantial, even with respect to claims that we believe have no merit. Due to the inherent uncertainty of the litigation process, the resolution of any particular legal claim or proceeding could adversely affect our business, operating results and financial condition.

From time to time, we have been, or may in the future be, involved in securities litigation or litigation arising from our acquisitions. We can provide no assurance as to the outcome of any such litigation matter in which we are a party. These types of matters are costly to defend and even if resolved in our favor, could have a material adverse effect on our business, financial condition, operating results and cash flow. Such litigation could also substantially divert the attention of our management and our resources in general. Uncertainties resulting from the initiation and continuation of securities or other litigation could harm our ability to obtain credit and financing for our operations and to compete in the marketplace. Because the price of our common stock has been, and may continue to be, volatile, we can provide no assurance that securities litigation will not be filed

against us in the future. In addition, we can provide no assurance that our past or future acquisitions will not subject us to additional litigation.

Securities Authorized for Issuance Under Equity Compensation Plans

See the information set forth in Part III, Item 12 of this Form 10-K.

Sales of Unregistered Securities

On October 5, 2016, we issued a Warrant to Comcast to purchase Warrant Shares of our common stock, representing a total of $30.0 million worth of common stock based on the average closing price over the 10-trading day period ended October 4, 2016, at an exercise price of $0.01 per Warrant Share.

The Warrant has a term of seven years from October 5, 2016. The Warrant provides for net share settlement that, if elected by Comcast, will reduce the number of Warrant Shares issued upon exercise to reflect net settlement of the exercise price. Comcast may also request cash settlement of the Warrant upon exercise in lieu of the issuance of Warrant Shares, however, such cash settlement is at our sole and absolute discretion. The Warrant vests 10% on issuance, and the remainder vests based on the achievement during the subsequent 30-month period by Comcast (or its designee) of certain milestones related to the deployment of a LoRaWAN™-based network in cities around the country. The number of Warrant Shares are subject to customary adjustment provisions for stock split, reclassification, reorganization, consolidation, merger, and similar transactions.

The Warrant was issued by us to Comcast in connection with an agreement regarding the intended trial deployment by Comcast of a LPWAN in the United States, based on our LoRa.

The issuance of the Warrant and the underlying Warrant Shares were not registered under the Securities Act of 1933, as amended (the “Securities Act”). The Warrant and the underlying Warrant Shares were issued in a private placement exempt from the registration requirements of the Securities Act, in reliance on the exemptions set forth in Section 4(a)(2) of the Securities Act. We did not make any other sales of unregistered securities during fiscal year 2017.

(2)	The Company acquired Gennum on March 20, 2012 and Cycleo SAS on March 7, 2012. Both of these acquisitions occurred during our fiscal year 2013 with Gennum being the more significant of the two. As a result, fiscal year 2013 reflects almost a full year of these acquisitions in our Consolidated Statements of Income.


Item 7.	Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and operating results should be read in conjunction with Item 6 "Selected Consolidated Financial Data" and our Consolidated Financial Statements and related Notes included elsewhere in this Annual Report on Form 10-K.

We report results on the basis of 52 and 53 week periods and our fiscal year ends on the last Sunday in January. The fiscal years ended January 29, 2017 and January 25, 2015 ea ch consisted of 52 weeks. The fiscal year ended January 31, 2016 consisted of 53 weeks.

Our end-customers are primarily OEMs and their suppliers, including Cisco Systems, Inc., Alphabet Inc., Huawei Technologies Co. Ltd., Itron, LG Electronics, Samsung Electronics Co. Ltd., Sharp Corporation, Sonova International and ZTE Corporation.

On March 4, 2015, we completed the acquisition of Triune, a privately-held supplier of wireless charging, isolated switching and power management platforms targeted at high and low power, high efficiency applications. Under the terms of the purchase agreement, we acquired all of the outstanding equity interests of Triune for an aggregate purchase price of $45.0 million consisting of $35.0 million cash paid at closing, with an additional cash consideration of $10.0 million which has since been paid. Subject to achieving certain future financial goals ("Triune Earn-out"), up to an additional $70.0 million of additional contingent consideration could have been paid over three years if certain revenue targets were achieved in each of the fiscal years 2016 through 2018. An additional payment of up to $16.0 million could have been paid after fiscal year 2018 if certain cumulative revenue and operating income targets are achieved. The Triune Earn-out targets for fiscal year 2017 and 2016 were not met and we do not expect to make any payments with regards to these periods which represented $36.0 million of the total $70.0 million opportunity. We do not expect fiscal year 2018 targets to be achieved. See Note 3 and Note 14 to our Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K. Our primary reason for the acquisition was to broaden our existing portfolio with platforms that are very complementary to our current market focus, including Triune's isolated switching platform and wireless charging platform.

On January 13, 2015, we completed the acquisition of select assets from EnVerv, a privately-held supplier of PLC and Smart Grid solutions targeted at advanced metering infrastructure, home energy management systems and IoT applications. We paid $4.9 million in cash at closing. See Note 3 to our Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

We operate and account for results in one reportable segment. See Note 17 to our Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K. In fiscal year 2016, we identified a total of five operating segments. Four of these operating segments aggregate into one reportable segment, the Semiconductor Products Group. The four operating segments aggregated into our one reportable segment all exhibit similar economic characteristics and we manage that business to a targeted gross margin range which all of the aggregated product lines are expected to meet. The remaining operating segment, the Systems Innovation Group (shown as "All others"), could not be aggregated with the other operating segments and did not meet the criteria for a separate reportable segment as defined by the guidance regarding segment disclosure. As a result, the financial activity associated with the Systems Innovation Group was reported separately from our Semiconductor Products Group. This separate reporting was included in the “All others” category. On August 5, 2016, we completed the divestiture of our Snowbush IP business (previously part of our Systems Innovation Group) to Rambus for a purchase price of $32.0 million in cash along with the opportunity to receive additional payments from Rambus through 2022 based upon a percentage of sales by Rambus of new products expected to be developed by Rambus from the disposed assets. Beginning in the third quarter of fiscal year 2017, we no longer have a Systems Innovation Group or an “All others” category, and therefore we have only four operating segments that aggregate into one reportable segment, the Semiconductor Products Group.

Gross margins for our Protection Products Group and Power and High-Reliability Products Group performed below our targeted range in fiscal year 2017 as their businesses were negatively impacted by an unfavorable product mix. The Power and High-Reliability Products Group has continued its on-going strategic transition away from certain markets (i.e., the personal computer market) that are characterized by non-differentiated offerings in sectors that are highly competitive. Specifically, the Power and High-Reliability Products Group is transitioning its product offerings to better support its current target markets, which include high-end consumer and medical, space, industrial and automotive applications that have historically enjoyed higher gross margins. Additionally, we believe that the recent addition of the wireless charging and isolated switching platforms

will allow us to accelerate this transition. The gross margin performance for the Protection Products Group in fiscal year 2017 was detrimentally impacted by its reliance on the handheld end-market, but showed improvement from fiscal year 2016 as a result of higher volumes driving improved absorption of fixed manufacturing costs.

Most of our sales to customers are made on the basis of individual customer purchase orders. Many customers include cancellation provisions in their purchase orders. Trends within the industry toward shorter lead-times and "just-in-time" deliveries have resulted in our reduced ability to predict future shipments. As a result, we rely on orders received and shipped within the same quarter for a significant portion of our sales. Sales made directly to customers during fiscal year 2017 were 35% of net sales. The remaining 65% of net sales were made through independent distributors.

Our business relies on foreign-based entities. Most of our subcontractors and suppliers, including third-party foundries that supply silicon wafers, are located in foreign countries, including China, Taiwan and Israel. For the fiscal year ended January 29, 2017 , approximately 25% of our silicon, in terms of cost of wafers purchased, was manufactured in China. Foreign sales for fiscal year 2017 constituted approximately 91% of our net sales. Approximately 76% of foreign sales in fiscal year 2017 were to customers located in the Asia-Pacific region. The remaining foreign sales were primarily to customers in Europe, Canada and Mexico.

We use several metrics as indicators of future potential growth. The indicators that we believe best correlate to potential future revenue growth are design wins and new product releases. There are many factors that may cause a design win or new product release to not result in revenue, including a customer decision not to go to system production, a change in a customer’s perspective regarding a product’s value or a customer’s product failing in the end-market. As a result, although a design win or new product introduction is an important step towards generating future revenue, it does not inevitably result in us being awarded business or receiving a purchase commitment.

Restructuring - fiscal 2017

In fiscal year 2017, we took targeted actions to better align our global operational footprint with our updated business strategies. As a result of these actions, we recorded restructuring charges of $2.3 million for employee termination and related charges. The benefit of these actions is expected to reduce our current operating expenses by approximately $4.0 million on an annual basis.

Restructuring - fiscal 2016

On July 15, 2015, we announced a worldwide reduction in force as part of an overall plan to align operating expenses with business conditions and leverage recent infrastructure investments. The reduction in force affected approximately 8% of our global workforce and was completed in our third quarter of fiscal year 2016. As a result of the reduction in force, we recorded restructuring charges of $4.5 million in fiscal year 2016. Such costs consisted primarily of termination benefits, including severance, which have been settled in cash. The benefits from this plan, after full implementation, were expected to reduce our current operating expenses by approximately $20.0 million on an annual basis.

Restructuring - fiscal 2015

In December 2014, we made a strategic decision to reduce our investment in the defense and microwave communications markets and to make additional reductions in our investments in the long-haul optical market. As a result of these actions, we recorded restructuring charges and impairments of certain intangible assets. Additionally, certain long-lived assets were determined to be impaired. The financial impact of these actions for the twelve month period ended January 25, 2015 , is presented below:



Restructuring charges
(in thousands)
Employee terminations and related costs	$	662
Contract termination costs	623
Total restructuring charges	$	1,285



Impairment of finite-lived intangibles

Contract commitments	2,983		—		—		2,983
	$	5,793	$	6	$	6,630	$	12,429

As a result of these restructuring actions, we realized operating cost savings of approximately $6.4 million in fiscal year 2016.

Results of Operations

Fiscal Year 2017 Compared With Fiscal Year 2016

All periods presented in the following summary of sales by major end-market reflect our current classification methodology (see Note 1 to our Consolidated Financial Statements in this Annual Report on Form 10-K for a description of each market category):



	Fiscal Years

	Net Sales			% Net Sales		Net Sales		% Net Sales		Change
Enterprise Computing	$	168,846		31	%	$	145,047	30	%	16	%
Industrial and Other	141,660			26	%	127,779		26	%	11	%

Total	$	544,272		100	%	$	490,219	100	%	11	%

Net Sales. Net sales for fiscal year 2017 were $544.3 million , an increase of 11% compared to $490.2 million for fiscal year 2016 which had benefited from an additional week compared to fiscal year 2017 . The net sales from this additional week were not significant. Fiscal year 2017 revenues within the enterprise computing end-market benefited from particular strength from our optical products which are well positioned for the current cycle of datacenter upgrades and increased deployments of PONs, particularly in China . The continued decline of 40Gbps and 100Gbps SerDes devices going into the long-haul optical market in the communications end-market was offset by strength in the wireless base station market primarily in China. Net sales increased in our high-end consumer end-market due to higher demand from our largest Korean customers as well as strong growth from our China smartphone customers.

In fiscal year 2018 , activity in the communications, enterprise computing and industrial end-markets is expected to improve, due to continued demand for datacenter upgrades, and the build-out of metro communications infrastructure, including wireless base stations (specifically in China) and IoT applications.

Gross Profit. Gross profit was $324.9 million and $293.1 million in fiscal years 2017 and 2016 , respectively. Our gross margin was 59.7% for fiscal year 2017 , comparable with 59.8% in fiscal year 2016 . Fiscal year 2017 performance benefited from a more favorable mix of higher margin product sales, the benefit of which was offset by the $5.4 million charge related to the Comcast Warrants which was reported as a reduction to revenue. We expect overall gross margins for fiscal year 2018 to remain consistent with our fiscal year 2017 performance.

Selling, General & Administrative Expenses

Selling, general and administrative ("SG&A") expenses for fiscal year 2017 increase d by $0.3 million as the benefit from the restructuring actions taken in fiscal year 2016, lower legal fees, and the non-reoccurrence of environmental reserves of $2.9 million were offset by an $8.0 million increase in share-based compensation resulting primarily from our higher stock price and a $9.5 million increase in our supplemental compensation costs associated with our improved financial performance.

Product Development and Engineering Expenses

Product development and engineering expenses for fiscal years 2017 and 2016 were $102.5 million and $113.7 million , respectively or a decrease of 10% . The decrease was primarily a result of our decision to reduce our investment in the defense and microwave communications markets and to sell our Snowbush IP business to Rambus. The savings from these actions were partially offset by lower recoveries from third parties for non-recurring engineering services.

The levels of product development and engineering expenses reported in a fiscal period can be significantly impacted, and therefore experience period over period volatility, by the number of new product tape-outs and by the timing of recoveries from non-recurring engineering services which are recorded as a reduction to product development and engineering expense.

Intangible Amortization

Intangible amortization was $25.3 million and $25.1 million in fiscal years 2017 and 2016 , respectively.

Gain on Disposition of Business Operations

In the third quarter of fiscal year 2017, we completed our divestiture of Snowbush IP to Rambus. As a result, we recognized a gain of $25.5 million on the disposition of this business.

Changes in the Fair Value of Contingent Earn-out Obligations

The contingent earn-out expense decrease d by $16.1 million in fiscal year 2017 primarily as a result of a significant reduction in our estimate of projected revenue associated with the Triune Earn-out.

We measure contingent earn-out liabilities at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy. We use a Monte Carlo valuation method as a valuation technique to determine the value of the earn-out liability. The significant unobservable inputs used in the fair value measurements are revenue projections over the earn-out period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs in isolation would result in a significantly higher or lower liability, with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount paid, and the difference between the fair value estimate and amount paid will be recorded in earnings. The Triune Earn-out targets for fiscal years 2017 and 2016 were not met and we do not expect to make any payments with regards to these periods which represented $36.0 million of the total $70.0 million opportunity.

Restructuring

We incurred $4.5 million for restructuring charges in fiscal year 2016 , for severance and contract cancellation liabilities related to our decision to reduce our investments in the defense and microwave communications and long-haul optical markets, realign product groupings, and align spending with anticipated demand levels. Restructuring charges in fiscal year 2017, at $2.2 million, were more limited and focused on better aligning our global operational footprint with our updated business strategies.

Interest Expense. Interest expense was $9.3 million and $7.8 million for fiscal years 2017 and 2016 , respectively. The $1.5 million increase is primarily related to the write-off of $0.5 million of debt issuance costs as a result of a debt modification that was completed in the fourth quarter of fiscal year 2017 and higher interest rates.

Our interest rate under our Amended and Restated Credit Agreement dated November 15, 2016 with certain lenders (the "Lenders") and HSBC Bank USA, National Association, as administrative agent (in such capacity, the "Administrative Agent") and as swing line lender and letter of credit issuer (the "Credit Agreement") can be influenced by our consolidated leverage ratio, as defined in the Credit Agreement ("Leverage Ratio"). Our Leverage Ratio is influenced by our consolidated indebtedness and our adjusted earnings before interest, taxes, depreciation and amortization. Historically, our Leverage Ratio under the Credit Agreement and prior credit agreement has been between 1.50 and 2.25 which resulted in an interest rate margin between 1.75% and 1.88%. Primarily as a result of declining revenue, our Leverage Ratio exceeded 2.50 at the end of fiscal year 2016 and the beginning of fiscal year 2017 which resulted in our rate margin increasing to 2.25%. As of result of higher sales, we ended fiscal year 2017 with a Leverage Ratio of approximately 1.69. We believe that our Leverage Ratio will continue to improve in the first quarter of fiscal year 2018 as a result of continued strength in sales trends. The impact of the benefit of improvements to our Leverage Ratio on our total interest costs is being offset by increases in the 30 day LIBOR rate. If the 30 day LIBOR rate increases 25 basis points, our interest costs for fiscal year 2018 will increase by $0.6 million.

Interest Income and Other Expense, Net. Interest income and other expense, net was an expense of $1.7 million in fiscal year 2017 compared to $1.8 million in fiscal year 2016 . Interest income earned in the past few years has been insignificant. The slightly higher expense in fiscal year 2017 was primarily related to the impact of unfavorable movements in foreign exchange rates.

Provision for Taxes. The provision for income taxes was $18.4 million for fiscal year 2017 compared to $8.9 million for fiscal year 2016 . The effective tax rates for fiscal years 2017 and 2016 were a tax provision of 25.2% and 43.6% , respectively. The effective tax rates for fiscal years 2017 and 2016 reflect the adverse impact of $5.6 million and $1.8 million respecti vely, related to a valuation reserve against our deferred tax assets.

Our effective tax rate in fiscal year 2017 differs from the statutory federal income tax rate of 35% due primarily to a valuation reserve against our deferred tax assets and certain undistributed foreign earnings for which no U.S. taxes are provided, because such earnings are indefinitely reinvested outside of the U.S. The effective tax rate in fiscal year 2017 is lower than the statutory federal income tax rate due to regional mix of income causing a portion of the earnings to be taxed at foreign tax rates which are less than the federal rate. During fiscal year 2017, we also received an income tax rate benefit for our research and development tax credits in the United Kingdom ("U.K") and Canada.

We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and tax basis of the assets and liabilities.

As of January 29, 2017 , we have a valuation allowance against our U.S. deferred tax assets of approximately $83.0 million. We are required to assess whether a valuation allowance should be recorded against our deferred tax assets ("DTAs") based on the consideration of all available evidence, using a "more likely than not" realization standard. The four sources of taxable income that must be considered in determining whether DTAs will be realized are; (1) future reversals of existing taxable temporary differences (i.e. offset of gross deferred tax assets against gross deferred tax liabilities); (2) taxable income in prior carryback years, if carryback is permitted under the tax law; (3) tax planning strategies and (4) future taxable income exclusive of reversing temporary differences and carry-forwards.

In assessing whether a valuation allowance is required, significant weight is to be given to evidence that can be objectively verified. We have evaluated our DTAs each reporting period, including an assessment of our cumulative income or loss over the prior three-year period, to determine if a valuation allowance was required. A significant negative factor in our assessment was our three-year cumulative loss history in the U.S. as of January 29, 2017 .

In fiscal years 2013 through 2015, our Canadian operations were in a cumulative loss position due to a loss generated in fiscal year 2013. However, as of the end of fiscal year 2016, Gennum was in a three year cumulative income position, since the loss that was generated in fiscal year 2013 was no longer included in the three year window for measuring income or loss. We are forecasting pretax income growth for Gennum over the next five years, and correspondingly estimated our Canadian-based taxes over the next five years. We compared the amount of taxes that we will owe in this period to our net deferred tax assets and concluded that we would be able to utilize our deferred tax assets without any concerns related to expiration.

We are forecasting pretax income growth for Gennum over the next five years, and correspondingly estimated our Canadian based taxes over the next five years. We compared the amount of taxes that we will owe in this period to our net deferred tax assets and concluded that we would be able to utilize our deferred tax assets without any concerns related to expiration.

We were able to conclude that the positive evidence related to long-term profitability and utilization of all deferred tax assets was sufficient to warrant a full release of the reserve on our Canadian deferred tax assets. As such, we released the entire reserve of approximately $7.2 million on our Canadian deferred tax asset in fiscal year 2016.

As we enter fiscal year 2018 , we expect our tax rate to face upward pressure as a result of a less favorable mix of foreign and domestic income and our expected continued inability to benefit from U.S. deferred tax assets as a result of our recent history of tax losses in the U.S.

As a global organization, we are subject to audit by taxing authorities in various jurisdictions. To the extent that an audit, or the closure of a statute of limitations, results in our adjusting our reserves for uncertain tax positions, our effective tax rate could experience extreme volatility since any adjustment would be recorded as a discrete item in the period of adjustment.

Total	$	490,219	100	%	$	557,885	100	%	(12	)%

Net Sales. Net sales for fiscal year 2016 were $490.2 million , a decrease of 12% from $557.9 million for fiscal year 2015 . Net sales for fiscal year 2016 benefited from an additional week compared to fiscal year 2015. Fiscal year 2016 revenues within the enterprise computing end-market benefited from particular strength from our optical products which were well positioned for the current cycle of datacenter upgrades and increased deployments of PONs, particularly in China. This strength was more than offset by the further decline in the Communications market driven by the anticipated weakness in 40Gbps and 100Gbps SerDes devices going into the long-haul optical market as our customers transitioned away from our solutions and lower net sales to the 4G/LTE wireless base station market. Net sales were also lower in our high-end consumer end market due to lower demand from our largest Korean customers due to their loss of world-wide market share. Revenue from the licensing of intellectual property was $3.4 million and $0.4 million in fiscal years 2016 and 2015, respectively.

Gross Profit. Gross profit was $293.1 million and $328.8 million in fiscal years 2016 and 2015 , respectively. Our gross margin was 59.8% for fiscal year 2016 , up from 58.9% in fiscal year 2015 . We incurred significant charges in fiscal year 2015 related to our strategic decision to reduce our investments in the long-haul optical and defense and microwave communications markets. These charges included $2.8 million of asset impairment charges and $3.0 million of charges related to settlement of contract commitments. Excluding the charges related to these business alignment decisions, our gross margin profile for fiscal years 2016 and 2015 were similar.

Selling, General & Administrative Expenses

Selling, general, and administrative expenses for fiscal year 2016 increase d by $9.0 million or 7% as a result of higher support costs related to our new enterprise resource planning ("ERP") software and the recurring amortization expense associated with our new ERP software of approximately $2.2 million per year. In fiscal year 2016, we recorded a reserve for certain environmental matters of $2.9 million and incurred approximately $6.8 million of costs associated with various legal matters, including our acquisition of Triune, our investment in MultiPhy Ltd., and our litigation actions against Active-Semi International, Inc. These costs were partially offset by $9.1 million of lower share-based compensation.

Product Development and Engineering Expenses

Product development and engineering expenses for fiscal years 2016 and 2015 were $113.7 million and $119.4 million , respectively or a decrease of 5% . The decrease was primarily a result of our decision to reduce our investment in the defense and microwave communications markets and to make additional reductions in our investments in the long-haul optical market, partially offset by higher costs associated with our acquisitions of Triune and select assets from EnVerv and lower recoveries from third parties for non-recurring engineering services.

Intangible Amortization

Intangible amortization was $25.1 million and $25.7 million in fiscal years 2016 and 2015 , respectively.

Intangible Asset Impairments

There were no intangible asset impairments in 2016. We recorded $11.6 million in intangible asset impairments in fiscal year 2015 related to our decision to reduce our investment in the defense and microwave communications markets and to make additional reductions in our investments in the long-haul optical market.

Changes in the Fair Value of Contingent Earn-out Obligations

The contingent earn-out expense decreased by $17.8 million in fiscal year 2016 primarily as a result of a significant reduction in our estimate of projected revenue associated with the Triune Earn-out.

We measure contingent earn-out liabilities at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy. We use a Monte Carlo valuation method as a valuation technique to determine the value of the earn-out liability. The significant unobservable inputs used in the fair value measurements are revenue projections over the earn-out period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs in isolation would result in a significantly higher or lower liability, with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount paid, and the difference between the fair value estimate and amount paid will be recorded in earnings. The Triune Earn-out targets for fiscal year 2016 were not met and we do not expect to make any payments with regards to this period which represented $13.0 million of the total $70.0 million opportunity.

Restructuring

In the second quarter of fiscal year 2016, we announced a worldwide reduction in force as part of an overall plan to align operating expenses with business conditions and leverage recent infrastructure investments. As a result of the reduction in force, we recorded restructuring charges of $4.5 million in fiscal year 2016.

We incurred $1.3 million for restructuring charges in fiscal year 2015, respectively, for severance and contract cancellation liabilities related to our decision to reduce our investments in the defense and microwave communications and long-haul optical markets, realign product groupings, and align spending with anticipated demand levels.

Interest Expense. Interest expense was $7.8 million and $5.9 million for fiscal year 2016 and 2015 , respectively. The $1.9 million increase is primarily related to higher levels of outstanding debt under our credit facilities and higher amortization costs associated with our interest rate hedge. Our interest rate under the Credit Agreement can be influenced by our Leverage Ratio. Our Leverage Ratio is influenced by our consolidated indebtedness and our adjusted earnings before interest, taxes, depreciation and amortization. Historically, our Leverage Ratio under the Credit Agreement has been between 1.50 and 2.25 which resulted in an interest rate margin of 1.75%. Primarily as a result of declining revenue, our Leverage Ratio exceeded 2.50 at the end of fiscal year 2016 which resulted in our rate margin increasing to 2.25%.

Interest Income and Other Expense, Net. Interest income and other expense, net was expense of $1.8 million in fiscal year 2016 compared to income of $0.2 million in fiscal year 2015 . Interest income earned in the past few years has been insignificant. The higher expense in fiscal year 2016 was primarily related to the impact of unfavorable movements in foreign exchange rates and higher interest costs associated with the Cycleo Amended Earn-Out discussed in Note 14 to our Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

Provision for Taxes . The provision for income taxes was $8.9 million for fiscal year 2016 compared to $8.5 million for fiscal year 2015 . The effective tax rates for fiscal years 2016 and 2015 were a tax provision of 43.6% and 23.4% , respectively. The effective tax rates for fiscal years 2016 and 2015 reflect the adverse impact of $1.8 million and $14.3 million respectively, related to a valuation reserve against our deferred tax assets.

Our effective tax rate in fiscal year 2016 differs from the statutory federal income tax rate of 35% due primarily to a valuation reserve against our deferred tax assets and certain undistributed foreign earnings for which no U.S. taxes are provided, because such earnings are indefinitely reinvested outside of the U.S. The effective tax rate in fiscal year 2016 is higher than the statutory federal income tax rate due to additional non-cash tax expense in the U.S. resulting from the reversal of a contingent liability (discussed in Note 14 to our Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K) and its related impact on a book-tax difference in the basis of goodwill. During fiscal years 2016 and 2015, we also received an income tax rate benefit for our research and development tax credits in the U.K. and Canada.

As of January 31, 2016, we have a valuation allowance against our U.S. deferred tax assets of approximately $77.4 million. We are required to assess whether a valuation allowance should be recorded against our DTAs based on the consideration of all available evidence, using a "more likely than not" realization standard. The four sources of taxable income that must be considered in determining whether DTAs will be realized are; (1) future reversals of existing taxable temporary differences (i.e. offset of gross deferred tax assets against gross deferred tax liabilities); (2) taxable income in prior carryback years, if carryback is permitted under the tax law; (3) tax planning strategies and (4) future taxable income exclusive of reversing temporary differences and carry-forwards.

In fiscal years 2013 through 2015, our Canadian operations were in a cumulative loss position due to a loss generated in fiscal year 2013. However, as of the end of fiscal year 2016, Gennum was in a three year cumulative income position, since the loss that was generated in fiscal year 2013 was no longer included in the three year window for measuring income or loss. We are forecasting pretax income growth for Gennum over the next five years, and correspondingly estimated our Canadian based taxes over the next five years. We compared the amount of taxes that we will owe in this period to our net deferred tax assets and concluded that we would be able to utilize our deferred tax assets without any concerns related to expiration.

We were able to conclude that the positive evidence related to long-term profitability and utilization of all deferred tax assets was sufficient to warrant a full release of the reserve on our Canadian deferred tax assets. As such, in the fourth quarter of fiscal year 2016, we released the entire reserve of approximately $7.2 million on our Canadian deferred tax assets.

After a review of the four sources of taxable income described above and in view of our three-year cumulative loss, we were not able to conclude that it is more likely than not that our U.S. DTAs will be realized. As a result, we recorded a full valuation allowance on our DTAs in the U.S, with a corresponding charge to the income tax provision of approximately $9.0 million. During the fourth quarter of fiscal year 2016, we revisited our analysis of whether a valuation allowance would be appropriate for our Canadian deferred tax assets, and concluded that enough positive evidence exists to fully release the reserve, with a corresponding benefit to the income tax provision of approximately $7.2 million. This resulted in a net charge to the income tax provision of approximately $1.8 million as of January 31, 2016.

Liquidity and Capital Resources

Our capital requirements depend on a variety of factors, including but not limited to, the rate of increase or decrease in our existing business base; the success, timing and amount of investment required to bring new products to market; revenue growth or decline; and potential acquisitions. We believe that we have the financial resources necessary to meet business requirements for the next 12 months, including funds needed for working capital requirements.

As of January 29, 2017 , our total stockholders’ equity was $605.3 million . At that date, we also had approximately $297.1 million in cash and cash equivalents and $241.0 million of borrowings, net of debt discount.

We believe that sources and uses of cash when used in conjunction with GAAP measures provide useful information to investors in evaluating our cash flows. Our primary sources and uses of cash for the corresponding periods are presented below (non-GAAP):

We incur significant expenditures in order to fund the development, design, and manufacture of new products. We intend to continue to focus on those areas that have shown potential for viable and profitable market opportunities, which may require additional investment in equipment and the hiring of additional design and application engineers aimed at developing new products. Certain of these expenditures, particularly the addition of design engineers, do not generate significant payback in the short-term. We plan to finance these expenditures with cash generated by our operations and our existing cash balances.

A meaningful portion of our capital resources, and the liquidity they represent, are held by our foreign subsidiaries. As of January 29, 2017 , our foreign subsidiaries held approximately $224.6 million of cash and cash equivalents compared to $170.7 million at January 31, 2016 . Earnings previously taxed in the U.S. of $18.1 million could be repatriated subject only to a 5% withholding tax, as we do not assert permanent reinvestment of earnings previously taxed in the U.S. As of January 29, 2017 , our foreign subsidiaries had $603.0 million of unremitted earnings for which no Federal or state taxes have been provided. Those historical earnings have been and are expected to continue to be permanently reinvested.

One of our primary goals is to improve the cash flows from our existing business activities. Additionally, we will continue to seek to maintain and improve our existing business performance with capital expenditures and, potentially, acquisitions and other investments that support achievement of our business strategies. Acquisitions may be made for either cash or stock consideration, or a combination of both.

Operating Activities

Net cash provided by operating activities is primarily due to net income adjusted for non-cash items plus fluctuations in operating assets and liabilities.

Operating cash flows for fiscal years 2017 and 2016 were impacted by several significant non-cash transaction related items including, for fiscal 2017 , depreciation, amortization and impairment expenses of $47.1 million and share-based compensation expense of $30.8 million . The significant non-cash transactions for fiscal 2016 included depreciation, amortization, and impairment expense of $48.9 million , share-based compensation expense of $20.5 million and the benefit of reductions in the fair value of contingent earn-out obligations of $16.4 million.

Investing Activities

Cash flows from investing activities is primarily attributable to capital expenditures, net of proceeds from sales of property, plant and equipment and proceeds from sales of investments. Investing activities are also impacted by acquisitions, net of any cash received.

On March 4, 2015, we acquired Triune, a privately-held supplier of wireless charging and power management platforms targeted at, among other things, high and low power, high-efficiency applications. Under the terms of the purchase agreement, we acquired all of the outstanding equity interest in Triune for a guaranteed minimum purchase price of $45.0 million which consisted of $35.0 million in cash paid at closing and $10.0 million to be paid at a future date ("Deferred Payment"). To fund the Triune acquisition, we borrowed $35.0 million under our prior revolving line of credit in March 2015. In September 2015, we paid $9.5 million of the Deferred Payment with the remaining $0.5 million being paid in the second quarter of fiscal year 2017. Subject to achieving certain future financial goals, up to $70.0 million of contingent consideration could have been earned if certain revenue targets were achieved through fiscal year 2018. An additional payment of up to $16.0 million could be paid after fiscal year 2018 if certain cumulative net revenue and contribution margin targets are achieved. We do not expect the Triune Earn-out targets to be achieved for fiscal year 2018 and we do not expect to pay any associated contingent consideration.

Capital expenditures were $32.9 million for fiscal year 2017 compared to $13.0 million for fiscal year 2016 . On November 4, 2016, we entered into an agreement to acquire the facility we were leasing in Burlington, Ontario, Canada for $12.1 million. The transaction closed on December 2016, and we used available cash on hand to fund this purchase. In fiscal year 2017 , we increased capital expenditure to support our business growth and the release of new products. In fiscal year 2018 , we expect our capital expenditures to be flat compared to our fiscal year 2017 levels as our decrease in real property purchases is offset by higher investments in test and manufacturing equipment to support higher demand levels and new product introductions. If product demand were to increase significantly beyond current projections, we would expect to increase capital spending to accommodate the growth. Similarly, to the extent practical, we would expect to decrease capital spending to address market contractions.

Financing Activities

Cash provided by financing activities is primarily attributable to borrowings under our revolving commitments offset by principal and interest payments related to our long-term debt and repurchase of outstanding common stock.

On May 2, 2013, we entered into a credit agreement with certain lenders (the "Prior Lenders") and HSBC Bank USA, National Association, as administrative agent and as swing line lender and letter of credit issuer (the "Prior Credit Agreement"). In accordance with this Prior Credit Agreement, the Prior Lenders provided us with senior secured first lien credit facilities in an

aggregate principal amount of $400.0 million, consisting of term loans in an aggregate principal amount of $150.0 million and revolving line of credit commitments in an aggregate principal amount of $250.0 million.

On November 15, 2016 (the "Closing Date"), we entered into the Credit Agreement to refinance the Prior Credit Agreement. We accounted for the Credit Agreement as a debt modification. Pursuant to the Credit Agreement, the Lenders provided us with senior secured first lien credit facilities in an aggregate principal amount of $400.0 million (the "Facilities"), consisting of term loans in an aggregate principal amount of $150.0 million (the "Term Loans") and revolving commitments in an aggregate principal amount of $250.0 million (the "Revolving Commitments"). Up to $40.0 million of the Revolving Commitments may be used to obtain letters of credit, up to $25.0 million of the Revolving Commitments may be used to obtain swing line loans, and up to $40.0 million of the Revolving Commitments may be used to obtain revolving loans and letters of credit in certain currencies other than U.S. Dollars ("Alternative Currencies"). Each of the Term Loans and the Revolving Commitments is scheduled to mature on November 12, 2021.

The Credit Agreement refinanced our existing $400.0 million senior secured first lien credit facilities. All of the proceeds of the new Term Loans were used to repay in full all of the obligations outstanding under the Prior Credit Agreement and to pay transaction costs in connection with such refinancing and the Credit Agreement. As of January 29, 2017 we have $146.3 million outstanding under our Term Loans and $97.0 million outstanding under our Revolving Commitments.

As of January 29, 2017 , $153.0 million of the new Revolving Commitments were undrawn. The proceeds of the new revolving credit facility may be used by us for capital expenditures, permitted acquisitions, permitted dividends, working capital and general corporate purposes.

The Credit Agreement provides that, subject to certain conditions, we may request, at any time and from time to time, the establishment of one or more additional term loan facilities and/or increases to the Revolving Commitments in an aggregate principal amount not to exceed the sum of (a) $150.0 million and (b) the aggregate principal amount of all voluntary prepayments of Term Loans made prior to the date of incurrence of such additional term loan facilities and/or increases to the Revolving Commitments; however, the Lenders are not required to provide such increase upon our request.

Interest on loans made under the Credit Agreement in U.S. Dollars accrues, at our option, at a rate per annum equal to (1) the Base Rate (as defined below) plus a margin ranging from 0.25% to 1.25% depending upon our consolidated leverage ratio or (2) LIBOR (determined with respect to deposits in U.S. Dollars) for an interest period to be selected by us plus a margin ranging from 1.25% to 2.25% depending upon our consolidated leverage ratio (such margin, the "Applicable Margin"). The "Base Rate" is equal to a fluctuating rate equal to the highest of (a) the prime rate of the Administrative Agent, (b) ½ of 1% above the federal funds effective rate published by the Federal Reserve Bank of New York and (c) one-month LIBOR (determined with respect to deposits in U.S. Dollars) plus 1.00%.

Interest on loans made under the Credit Agreement in Alternative Currencies accrues at a rate per annum equal to LIBOR (determined with respect to deposits in the applicable Alternative Currency) (other than loans made in Canadian Dollars, for which a special reference rate for Canadian Dollars applies) for an interest period to be selected by us plus the Applicable Margin.

The outstanding principal balance of the Term Loans will be subject to repayment in equal quarterly installments beginning on the last day of our fiscal quarter ending closest to January 31, 2017 in an amount equal to 10.0% per annum of the original principal amount of the Term Loans on the Closing Date in the first two years after such date, 12.5% per annum in years three and four after such date, and 15.0% per annum in year five after such date, with the balance being due at maturity on November 12, 2021. No amortization is required with respect to the revolving credit facility. We may voluntarily prepay borrowings under the new credit facilities at any time and from time to time, without premium or penalty, other than customary "breakage costs" and fees for LIBOR-based loans.

The Term Loans must be mandatorily prepaid using the proceeds of certain dispositions of assets and receipt of insurance proceeds, subject to agreed upon thresholds and exceptions and customary reinvestment rights.

We currently have in effect a stock repurchase program that was initially approved by our Board of Directors in March 2008. This program represents one of our principal efforts to return value to our stockholders. During fiscal years 2017 and 2016 , we repurchased shares of common stock under this program for $1.0 million and $57.3 million , respectively. As of January 29, 2017 , we had repurchased $136.7 million in shares of our common stock under the program since inception and the current remaining authorization under the program is $61.7 million .

In fiscal years 2017 and 2016 , we received $5.8 million in proceeds from the exercise of stock options. We do not directly control the timing of the exercise of stock options. Such exercises are independent decisions made by grantees and are influenced most directly by the stock price and the expiration dates of stock option awards. Such proceeds are difficult to forecast, resulting from several factors which are outside our control. We believe that such proceeds will remain a nominal source of cash in the future.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, as those arrangements are defined by the SEC, that are reasonably likely to have a material effect on our financial condition, revenues or expenses, operating results, liquidity, capital expenditures or capital resources.

We do not have any unconsolidated subsidiaries or affiliated entities. We have no special purpose or limited purpose entities that provide off-balance sheet financing, liquidity or market or credit risk support. We do not engage in leasing, hedging, research and development services, or other relationships that expose us to liability that is not reflected on the face of the Consolidated Financial Statements.

Noted below under "Contractual Obligations" are various commitments we have associated with our business, such as lease commitments and open purchase obligations, which are not recorded as liabilities on our balance sheet because we have not yet received the related goods or services as of January 29, 2017 .

Contractual Obligations

Presented below is a summary of our contractual obligations as of January 29, 2017 .



(in thousands)	Less than 1 year		1-3 years		4-5 years		After 5 years		Total

(1) Amounts include expected payments under the current Swiss plan through 2026.

The table above includes the interest payments we owe on our long-term debt. We have assumed no additional borrowings or repayments under our revolving credit facility. For debt that has variable rate interest, we have calculated future interest obligations based on the interest rate for that debt as of January 29, 2017 .

Capital purchase commitments and other open purchase commitments are for the purchase of plant, equipment, raw material, supplies and services. They are not recorded as liabilities on our balance sheet as of January 29, 2017 , as we have not yet received the related goods or taken title to the property.

The table above does not include earn-out payments we may owe as part of our acquisition of Triune. The Triune Earn-out targets for fiscal years 2016 and 2017 were not met and we do not expect to make any payments with regards to these periods which represented $36.0 million of the total $70.0 million opportunity. Based on our most current forecasts, we do not expect to make any earn-out payments with regards to this acquisition.

As part of our acquisition of Cycleo SAS ("Cycleo") and the terms of the amended earn-out agreement entered into with the former Cycleo stockholders, we have agreed to pay up to $16.0 million of consideration over a five year period if certain revenue and operating income targets are achieved in each of the five measurement periods. See Note 14 to our Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

We maintain a deferred compensation plan for certain officers and key executives that allow participants to defer a portion of their compensation for future distribution at various times permitted by the plan. Our liability for deferred compensation under this plan was $24.1 million and $19.4 million as of January 29, 2017 and January 31, 2016 , respectively, and is included in accrued liabilities and other long-term liabilities on the balance sheet and in the table above. The plan provides for a discretionary Company match up to a defined portion of the employee’s deferral, with any match subject to a vesting period.

We have purchased whole life insurance on the lives of some of our current and former deferred compensation plan participants. This Company-owned life insurance is held in a grantor trust and is intended to cover a majority of the costs of our

deferred compensation plan. The cash surrender value of our Company-owned life insurance was $18.9 million and $16.8 million as of January 29, 2017 and January 31, 2016 , respectively.

Inflation

Inflationary factors have not had a significant effect on our performance over the past several years. A significant increase in inflation would affect our future performance.

Critical Accounting Policies and Estimates

Our Consolidated Financial Statements are prepared in accordance with GAAP. In connection with the preparation of our Consolidated Financial Statements, we are required to make assumptions and estimates about future events, and apply judgments that affect the reported amounts of assets, liabilities, revenue, expenses and the related disclosures. We base our assumptions, estimates and judgments on historical experience, current trends and other factors that management believes to be relevant at the time our Consolidated Financial Statements are prepared. On a regular basis, management reviews the accounting policies, assumptions, estimates and judgments to ensure that our Consolidated Financial Statements are presented fairly and in accordance with GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates, and such differences could be material.

Our significant accounting policies are discussed in Note 2 to our Consolidated Financial Statements, included in Item 8, of this Annual Report on Form 10-K. We believe that the following accounting estimates are the most critical to aid in fully understanding and evaluating our reported financial results, and they require our most difficult, subjective or complex judgments, resulting from the need to make estimates about the effect of matters that are inherently uncertain. We have reviewed these critical accounting estimates and related disclosures with the Audit Committee of our Board of Directors.

Revenue and Cost of Sales

We recognize product revenue when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectability is probable. Product design and engineering recoveries are recognized during the period in which services are performed and are recorded as an offset to the related expenses. Historically, these recoveries have not exceeded the cost of the related development efforts. We include revenue related to technology licenses as part of "Net sales." Historically, revenue from these arrangements has not been significant though it is part of our recurring ordinary business.

On October 5, 2016, we issued a Warrant to Comcast to purchase up to 1,086,957 Warrant Shares of our common stock. The cost of the Warrant is recognized as an offset to net sales over the respective performance period since the Warrant was issued to our customer in exchange for services.

We record a provision for estimated sales returns in the same period as the related sales are recorded. We base these estimates on historical sales returns and other known factors. Actual returns could be different from our estimates and current provisions for sales returns and allowances, resulting in future charges to earnings.

We record a provision for sales rebates in the same period as the related sales are recorded. These estimates are based on sales activity during the period. Actual rebates given could be different from our estimates and current provisions for sales rebates, resulting in future charges to earnings.

We defer revenue recognition on shipment of products to certain customers, principally distributors, under agreements which provide for limited pricing credits or product return privileges, until these products are sold through to end users or the return privileges lapse. For sales subject to certain pricing credits or return privileges, the amount of future pricing credits or inventory returns cannot be reasonably estimated given the relatively long period in which a particular product may be held by the customer. Therefore, we have concluded that sales to customers under these agreements are not fixed and determinable at the date of the sale and revenue recognition has been deferred. We estimate the deferred gross margin on these sales by

applying an average gross margin to the actual gross sales. The average gross margin is calculated for each category of material using current standard costs. The estimated deferred gross margin on these sales, where there are no outstanding receivables, is recorded within the consolidated balance sheets under the heading of "Deferred revenue." There were no significant impairments of deferred cost of revenues in fiscal years 2017 or 2016.

The following table summarizes the deferred revenue balance:



(in thousands)	January 29, 2017			January 31, 2016
Deferred revenues	$	11,419		$	5,991
Deferred cost of revenues	(2,246		)	(1,139		)
Deferred revenue, net	9,173			4,852
Deferred product design and engineering recoveries	2,886			3,776
Total deferred revenue	$	12,059		$	8,628

Allowances Against Accounts Receivable

We evaluate the collectability of our accounts receivable based on a combination of factors. If we are aware of a customer’s inability to meet its financial obligations to us, we record an allowance to reduce the net receivable to the amount we reasonably believe we will be able to collect from the customer. For all other customers, we recognize allowances for doubtful accounts based on the length of time the receivables are past due, the current business environment, the size and number of certain large accounts and our historical experience. If the financial condition of our customers were to deteriorate or if economic conditions worsen, additional allowances may be required in the future.

The portion of the estimate for sales returns where there are outstanding receivables is recorded on the balance sheet as a reduction to accounts receivable.

The estimated sales rebate for sales for which there are no outstanding receivables is recorded on the balance sheet under the heading of "Accrued liabilities." The portion of the estimated sales rebate where there are outstanding receivables is recorded on the balance sheet as a reduction to accounts receivable.

A summary of allowances against accounts receivable are presented below:



(in thousands)	January 29, 2017			January 31, 2016
Allowance for doubtful accounts	$	(2,696	)	$	(889	)
Sales rebate allowance	(2,571		)	(5,006		)
Sales return allowance	(1,795		)	(517		)
Other allowances	(1,168		)	(1,381		)
Total	$	(8,230	)	$	(7,793	)

Inventory Valuation

Our inventories are stated at lower of cost or market and consist of materials, labor and overhead. We determine the cost of inventory by the first-in, first-out method. At each balance sheet date, we evaluate our ending inventories for excess quantities and obsolescence. This evaluation includes analysis of sales levels by product and projections of future demand. In order to state our inventory at lower of cost or market, we maintain specific reserves against our inventory which serve to write-down our inventories to a new cost basis. If future demand or market conditions are less favorable than our projections, a write-down of inventory may be required, and would be reflected in cost of goods sold in the period the revision is made. We write down inventory as a result of excess and obsolete inventories, or when we believe that the net realizable value of inventories is less than the carrying value.

Business Combinations

Business combinations are accounted for at fair value. Acquisition costs are expensed as incurred and recorded in general and administrative expenses; in-process research and development is recorded at fair value as an indefinite-lived intangible asset at the acquisition date; restructuring costs associated with a business combination are expensed subsequent to the acquisition date; contingent consideration obligations are recorded at fair value on the date of acquisition, with increases or decreases in the fair value arising from changes in assumptions or discount periods recorded as contingent consideration expenses in the Consolidated Statements of Income in subsequent periods; and changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date generally affect income tax expense. All changes that do not qualify as measurement period adjustments are included in current period earnings. The fair values assigned to tangible and intangible assets acquired and liabilities assumed, including contingent consideration, are based on management’s estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. Significant judgment is required in estimating the fair value of intangible assets acquired in a business combination and in assigning their respective useful lives. The fair value estimates are based on available historical information and on future expectations and assumptions deemed reasonable by management at the time.

We measure contingent earn-out liabilities at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy. On a quarterly basis, we use a Monte Carlo valuation method as a valuation technique to determine the value of the earn-out liability. The significant unobservable inputs used in the fair value measurements are revenue projections over the earn-out period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs in isolation would result in a significantly higher or lower liability, with a higher liability capped by the contractual maximum of the contingent earn-out obligation.

If the actual results differ from the estimates and judgments we utilized, the amounts recorded in the Consolidated Financial Statements could result in a possible impairment of the intangible assets and goodwill, or require acceleration of the amortization expense of finite-lived intangible assets.

Contingencies and Litigation

We record accruals for contingencies when it is probable that a liability has been incurred and the amount can be reasonably estimated. These accruals are adjusted periodically as assessments change or additional information becomes available. Individually significant contingent losses are accrued when probable and reasonably estimable.

The legal defense costs we accrue are based on reviews by outside counsel, in-house counsel and management, and some of the significant factors considered in the review of these reserves are as follows: the actual costs incurred by us; the development of our legal defense strategy and structure in light of the scope of the litigation; the number of cases being brought against us; the costs and outcomes of completed trials and the most current information regarding anticipated timing, progression, and related costs of pre-trial activities and trials in the associated litigation.

In those situations where we are unable to determine the best estimate within the range of loss, we will record the minimum amount in the identified range of probable loss.

Share-Based Compensation

We measure compensation cost for all share-based payments (including stock options) at fair value using valuation models, which consider, among other things, estimates and assumptions on the rate of forfeiture, expected life of options and stock price volatility and market value of our common stock. Additionally, for awards with a performance condition, we use financial forecasts that use assumptions that are consistent with those used for other valuation exercises, including goodwill valuation and asset impairment assessments. If any of the assumptions used in the valuation model change significantly, share-based compensation expense may differ materially in the future from that recorded in the current period and actual results may differ from estimates. See the information set forth in Part II, Item 5 of this Annual Report on Form 10-K for market information detailing the trading prices of our common stock.

Impairment of Goodwill, Other Intangibles and Long-Lived Assets

Goodwill

Goodwill is the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations accounted for under the acquisition method. Goodwill is not amortized but is tested for impairment using either a qualitative assessment or a two-step method.

As part of the annual goodwill impairment test, we have the option to perform a qualitative assessment of a reporting unit's goodwill for impairment. If we choose to perform a qualitative assessment and determine the fair value more likely than not exceeds the carrying value of a reporting unit, no further evaluation is necessary.

In conducting the qualitative assessment, we consider relevant events or circumstances that affect the fair value or carrying amount of a reporting unit. Examples of events and circumstances include macroeconomic conditions, industry and market considerations, overall financial performance, events affecting a reporting unit and capital markets pricing. We place more weight on the events and circumstances that most affect the reporting unit’s fair value or the carrying amount of its net assets.

When we perform the two-step method, step one is the identification of potential impairment. This involves comparing the fair value of each reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds the carrying amount, the goodwill of the reporting unit is considered not impaired and the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the impairment test is performed to measure the amount of impairment loss, if any. We test by reporting unit, goodwill and other indefinite-lived intangible assets for impairment at November 30 or more frequently if we believe indicators of impairment exist or if we make changes to a reporting unit with assigned goodwill.

For our two-step method annual impairment review, we primarily use an income approach, which incorporates multi-period excess earnings present value techniques (discounted cash flows) as well as other generally accepted valuation methodologies to determine the fair value of the assets using Level 3 inputs. Our assumptions incorporate judgments as to the price received to sell a reporting unit as a whole in an orderly transaction between market participants at the measurement date. Considering the integration of our operations, we have assumed that the highest and best use of a reporting unit follows an “in-use” valuation premise.

Significant management judgment is required in determining the estimations of future cash flows, which is dependent on internal forecasts, the long-term rate of growth for our business, the life over which cash flows will occur, and the weighted average cost of capital. Our calculations include sensitivity analysis of key assumptions such as a 10% increase in the weighted-average cost of capital, a 10% increase in the effective tax rate or a 5% decline in our compound annual growth rate.

The value of our intangible assets, including goodwill, could be impacted by future adverse changes such as: (i) any future declines in our operating results, (ii) a decline in the valuation of technology company stocks, including the valuation of our common stock, (iii) a significant slowdown in the worldwide economy and the semiconductor industry or (iv) any failure to meet the performance projections included in our forecasts of future operating results.

The assumptions we have used are consistent with the plans and estimates that we use to manage our business and change year to year based on operating results, competitive conditions, customer preferences, market conditions and other factors. It is possible, however, that these assumptions are incorrect. We could incur impairment charges in a future period if our actual results or the assumptions used in future impairment analysis are lower than the original assumptions used to assess the recoverability of these assets.

As of November 30, 2016 , our reporting units with assigned goodwill were as follows:



(in thousands)	Balance as of November 30, 2016
Signal Integrity Products	$	261,891
Power and High-Reliability Products	49,384
Wireless and Sensing Products	18,428
Total	$	329,703

In the fourth quarter of fiscal year 2017 , we completed our qualitative assessment of any potential goodwill impairment and concluded that there were no indications of impairment as of January 29, 2017 . Our fiscal year 2016 quantitative assessment of potential goodwill impairment concluded that the fair value of the Signal Integrity Products Group exceeded its carrying value by 47% and the fair value of the Wireless and Sensing Products Group exceeded its carrying value by over 258%. The fair value of the Power and High-Reliability Group exceeded its carrying value by 213%.

Other Intangibles and Long-lived Assets

We review indefinite-lived intangible assets for impairment as of November 30, the date of our annual goodwill impairment review or whenever events or changes in circumstances indicate the carrying value may not be recoverable. Recoverability of indefinite-lived intangible assets is measured by comparing the carrying amount of the asset to the future discounted cash flows that asset is expected to generate.

Finite-lived intangible assets resulting from business acquisitions or technology licenses purchased are amortized on a straight-line basis over their estimated useful lives. The useful lives of acquisition-related intangible assets represent the point where over 90% of realizable undiscounted cash flows for each intangible asset are recognized. The assigned useful lives are consistent with our historical experience with similar technology and other intangible assets owned by us. The useful life of technology licenses is usually based on the term of the agreement.

Acquired in-process research and development is recorded at fair value as of the date of acquisition as an indefinite-lived intangible asset until the completion or abandonment of the associated research and development efforts or impairment. Upon completion of development, acquired in-process research and development assets are transferred to finite-lived intangible assets and amortized over their useful lives.

We record impairment losses on long-lived assets used in operations when indicators of impairment, such as reductions in demand or significant economic slowdowns in the semiconductor industry, are present. Reviews are performed to determine whether the carrying value of an asset is impaired, based on comparisons to undiscounted expected future cash flows. If this comparison indicates that there is impairment, the impaired asset is written down to fair value, which is typically calculated using: (i) quoted market prices and/or (ii) discounted expected future cash flows utilizing a discount rate. Impairment is based on the excess of the carrying amount over the fair value of those assets.

Using the cost approach, we determined fair values of individual tangible long-lived assets based upon the cost to reproduce the long-lived asset taking into account the age, condition, inflation using the U.S. Bureau of Labor Statistics and Marshall Valuation Services, and cost to ready the long-lived asset for its intended use. Additionally, we considered the potential existence of functional and economic obsolescence and quantified these elements in our cost approach as appropriate.

We recognized and allocated to tangible long-lived assets no impairment loss during the fiscal year ended January 29, 2017 and $0.6 million and $9.4 million during the fiscal years ended January 31, 2016 and January 25, 2015 , respectively, which reduced the cost basis in the corresponding assets. Also, we reassessed the estimated remaining useful lives of these assets and adjusted accordingly our estimates of future depreciation expense.

For intangible long-lived assets, which consist of core technology and customer relationships, we used the multi-period excess earnings method, an income approach, or the replacement cost method (a cost approach), to determine fair value. The multi-period excess earnings method, a form of the income approach, estimates the value of the asset based on the present value of the after-tax cash flows attributable to the intangible asset, which includes our estimates of forecasted revenue, operating margins, taxes and discount rate. The replacement cost method incorporates a market participant’s assumption that an in-use premise is the highest and best use of customer relationships and core technology. We estimated the cost we would incur to rebuild or re-establish the intangible asset and the associated effort required to develop it.

We recorded impairment losses related to intangible long-lived assets as summarized below. Also, we reassessed the estimated remaining useful lives of these long-lived intangible assets and adjusted accordingly our estimates of future amortization expense.

Accounting for Income Taxes

The provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets and liabilities are expected to be realized or settled. We record a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized.

We evaluate whether it is more likely than not that forecasted income, including income that may be generated as a result of certain tax planning strategies, together with future reversals of existing taxable temporary differences, will be sufficient to fully recover the deferred tax assets. In the event that we determine all or part of the net deferred tax assets are not realizable in the future, we will record an adjustment to the valuation allowance that would be charged to earnings in the period such determination is made. In determining whether a valuation allowance is required, we consider projected taxable income and our historical performance. The most significant assumptions used in preparing projections of taxable income include forecasting the levels of income by region and the amount of deductible stock based compensation.

We recognize tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the Consolidated Financial Statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of GAAP and complex tax laws. Resolution of these uncertainties in a manner inconsistent with our expectations could have a material impact on our financial condition and operating results.

The income tax effects of share-based payments are recognized for financial reporting purposes only if such awards are expected to result in a tax deduction. We do not recognize a deferred tax asset for an excess tax benefit (that is, a tax benefit that exceeds the amount of compensation cost recognized for the award for financial reporting purposes) that has not been realized. In determining when an excess tax benefit is realized, we have elected to follow the ordering provision of the tax law.

In addition to the risks to the effective tax rate discussed above, the effective tax rate reflected in forward-looking statements is based on current enacted tax law. Significant changes in enacted tax law could materially affect these estimates.

In general, the amount of taxes we pay will differ from our reported tax provision as a result of differences between accounting for income under GAAP and accounting for taxable income. Typical book-tax differences include expense related to equity compensation, deemed dividends, depreciation, litigation expense and amortization of intangible assets. As a result of these book-tax differences, our tax payments are expected to differ from our tax provision during the next three years.

For intra-entity differences between the tax basis of an asset in the buyer’s tax jurisdiction and their cost as reported in the Consolidated Financial Statements, we do not recognize a deferred tax asset. Income taxes paid on intra-entity profits on assets remaining within the group are accounted for as prepaid taxes.

We continually review our position on undistributed earnings from our foreign subsidiaries to determine whether those earnings are indefinitely reinvested offshore. Domestic and foreign operating cash flow forecasts are reviewed to determine the sources and uses of cash. Based on these forecasts, we determine the need to accrue deferred tax liabilities associated with our undistributed earnings offshore.

New Accounting Standards

New accounting standards are discussed in Note 2 to our Consolidated Financial Statements, included in Item 8, of this Annual Report on Form 10-K.


Item 7A.	Quantitative and Qualitative Disclosures About Market Risk

We are subject to a variety of market risks, including commodity risk and the risks related to foreign currency, interest rates and market performance that are detailed below. Many of the factors that can have an impact on our market risk are external to us, and so we are unable to fully predict them.

Market Conditions

A deterioration of global economic conditions can impact demand for our products which could result in changes in customer order patterns, including order cancellations, and changes in the level of inventory held by vendors.

Commodity Risk

We are subject to risk from fluctuating market prices of certain commodity raw materials, particularly gold, that are incorporated into our end products or used by our suppliers to process our end products. Increased commodity prices are passed on to us in the form of higher prices from our suppliers, either in the form of general price increases or a commodity surcharge. Although we generally deal with our suppliers on a purchase order basis rather than on a long-term contract basis, we generally attempt to obtain firm pricing for volumes consistent with planned production. Our gross margins may decline if we are not able to increase selling prices of our products or obtain manufacturing efficiencies to offset the increased cost. We do not enter into formal hedging arrangements to mitigate against commodity risk.

Foreign Currency Risk

As a global enterprise, we face exposure to adverse movements in foreign currency exchange rates and we could experience foreign currency exchange gains or losses. Our foreign currency exposures may increase over time as our level of activity in foreign markets grows. Changes in rates could have an adverse impact upon our financial results.

Prior to fiscal year 2017, we did not utilize foreign currency hedging products to mitigate foreign currency risks. In fiscal year 2017, we entered into forward contracts to hedge a significant portion of our exposure to the Canadian dollar ("CAD"), Swiss Franc ("CHF") and British Pound Sterling ("GBP"). As of January 29, 2017 , we held forward contracts to hedge the GBP at levels that are expected to cover a significant portion of our anticipated fiscal year 2018 GBP exposure. All data relating to our derivative positions is presented in accordance with authoritative guidance. Accordingly, these cash flow hedges are designated for hedge accounting treatment and gains and losses on these contracts are recorded in accumulated other comprehensive income in stockholder’s equity and reclassified into earnings at the time that the related transactions being hedged are recognized in earnings. Please see Note 19 to our Consolidated Financial Statements in Part I, Item 1 of this Annual Report on Form 10-K for further discussion of our derivative instruments.

A relatively small amount of our monetary assets and liabilities are denominated in foreign currencies, principally the CHF, CAD, Mexican Peso ("MXN"), GBP and the Euro ("EUR"). Fluctuations in these currencies relative to the U.S. dollar ("USD") will result in transaction gains or losses included in net earnings.

All of our foreign sales, which amounted to $495.3 million in fiscal year 2017 , are denominated in USD. Currency exchange rate fluctuations in foreign countries where we do business could harm our business by resulting in pricing that is not competitive with prices denominated in local currencies.

For fiscal year 2017 , we spent approximately 70.3 million in CAD, 14.6 million in GBP, 17.3 million in CHF, 6.7 million in EUR, 66.2 million in Chinese Yuan, and 128.5 million in MXN for operating expenses.

In general, we purchase foreign currencies on a spot basis as needed to fund local operations. As of January 29, 2017 , we held cash funds of 1.1 million denominated in CAD, 2.5 million denominated in GBP, 1.5 million denominated in CHF, and 2.2 million denominated in EUR. We did not hold a significant amount of other foreign currencies. If rates of these foreign currencies were to strengthen or weaken relative to the USD, we would realize gains or losses in converting these funds back into USD.

An adverse change of the U.S. Dollar against the Company’s foreign currency operating expenses of 10%, after taking into account balance sheet hedges, would have resulted in an adverse impact on income before taxes of $8.2 million as of January 29, 2017 .

Interest Rate and Credit Risk

We do not engage in the trading of derivative financial instruments in the normal course of business to mitigate our risk related to interest rates. In the event interest rates were to increase 100 basis points and holding all other variables constant, annual net income and cash flows for the following year would decrease by approximately $2.4 million as a result of our variable-rate debt. The effect of the 100 basis points increase would not be expected to significantly impact the fair value of our variable-rate debt.

Interest rates affect our return on excess cash and investments. As of January 29, 2017 , we had $297.1 million of cash and cash equivalents and no temporary or long-term investments. A majority of our cash and cash equivalents generate interest income based on prevailing interest rates. Investments and cash and cash equivalents generated interest income of $0.2 million in fiscal year 2017 . A significant change in interest rates would impact the amount of interest income generated from our cash and investments. It would also impact the market value of our investments.

Our investments are primarily subject to credit risk. Our investments are managed by a limited number of outside professional managers following investment guidelines set by us. Such guidelines prescribe credit quality, permissible investments, diversification, and duration restrictions. These restrictions are intended to limit risk by restricting our investments to high quality debt instruments with relatively short-term durations. Our investment strategy limits investment of new funds and maturing securities to U.S. Treasury, Federal agency securities, high quality money market funds and time deposits with our principal commercial banks.

SEMTECH CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 : Organization and Basis of Presentation

Semtech Corporation (together with its consolidated subsidiaries, the "Company" or "Semtech") is a global supplier of analog and mixed-signal semiconductor products. The end-customers for the Company’s products are primarily original equipment manufacturers ("OEMs") that produce and sell electronics.

The Company designs, develops and markets a wide range of products for commercial applications, the majority of which are sold into the enterprise computing, communications, high-end consumer and industrial end-markets.

Enterprise Computing : datacenters, passive optical networks, desktops, notebooks, servers, monitors, printers and other computer peripherals.

Communications : base stations, optical networks, carrier networks, switches and routers, cable modems, wireless LAN and other communication infrastructure equipment.

High-End Consumer : handheld products, smartphones, wireless charging, set-top boxes, digital televisions, tablets, digital video recorders and other consumer equipment.

Industrial : video broadcast equipment, automated meter reading, Internet of Things ("IoT"), smart grid, wireless charging, military and aerospace, medical, security systems, automotive, industrial and home automation and other industrial equipment.

Fiscal Year

The Company reports results on the basis of 52 and 53 week periods and ends its fiscal year on the last Sunday in January. The fiscal years ended January 29, 2017 and January 25, 2015 each consisted of 52 weeks. The fiscal year ended January 31, 2016 consisted of 53 weeks.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”). All intercompany balances have been eliminated.

On March 4, 2015, the Company completed the acquisition of Triune Systems, L.L.C. ("Triune"). On January 13, 2015, the Company completed the acquisition of select assets from EnVerv, Inc. ("EnVerv"). The consolidated financial statements include the operating results of Triune and EnVerv commencing as of the acquisition dates.

Segment Information

The Company's Chief Executive Officer ("CEO") has been identified as the Chief Operating Decision Maker ("CODM") as defined by guidance regarding segment disclosures (see Note 16 for further discussion). In fiscal year 2016, the Company identified five operating segments in total. Four of the operating segments aggregated into one reportable segment, the Semiconductor Products Group. The remaining operating segment, the Systems Innovation Group (shown as "All others"), could not be aggregated with the other operating segments and did not meet the criteria for a separate reportable segment as defined by the guidance regarding segment disclosure. As a result, the financial activity associated with the Systems Innovation Group was reported separately from the Company's Semiconductor Products Group. This separate reporting was included in the "All others" category. On August 5, 2016, the Company completed its divestiture of its Snowbush Intellectual Property ("Snowbush IP") business (previously part of the Company’s Systems Innovation Group) to Rambus Inc. ("Rambus") for a purchase price of $32.0 million in cash along with the opportunity to receive additional payments from Rambus through 2022 based upon a percentage of sales by Rambus of new products expected to be developed by Rambus from the disposed assets. Therefore, as of January 29, 2017 , the Company no longer has a Systems Innovation Group or an "All others" category, resulting in four operating segments that aggregate into one reportable segment, the Semiconductor Products Group.

Use of Estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Note 2 : Significant Accounting Policies

Cash and Cash Equivalents

The Company considers all highly-liquid investments with an original maturity of 90 days or less and money market mutual funds to be cash equivalents. The Company maintains cash balances and cash equivalents in highly-qualified financial institutions. At various times such amounts are in excess of insured limits. Cash equivalents can consist of money market mutual funds, government and corporate obligations and bank time deposits.

The Company had restricted cash and deposits associated with various commitments of $5.3 million and $0.5 million as of January 29, 2017 and January 31, 2016 , respectively. Such cash is classified as restricted cash and presented in "Other assets" within the consolidated balance sheets. The cash inflows and outflows related to the restricted cash and deposits are classified as investing activities in the Company's Consolidated Statements of Cash Flows.

Investments

The Company’s investment policy restricts investments to high credit quality investments with limits on the length to maturity and the amount invested with any one issuer. These investments, especially corporate obligations, are subject to default risk. The Company classifies its investments as available-for-sale ("AFS") and reports these investments at fair value, with unrealized gains and losses, net of tax, recorded in accumulated other comprehensive income (loss). Realized gains or losses on AFS investments are recorded in "Interest income and other (expense) income, net" in the Consolidated Statements of Income. The Company recognizes losses in the income statement when it determines that declines in the fair value of its investments below their cost are other-than-temporary.

The Company has minority equity investments in privately held companies that are classified in other long-term assets in the consolidated balance sheets. Substantially, all of these investments are carried at cost because the Company does not have the ability to exercise significant influence over the company. The Company monitors these investments for impairment and makes appropriate reductions to the carrying value when necessary. As of January 29, 2017 and January 31, 2016 , the Company had aggregate net investments under the cost method of accounting of $27.1 million and $20.2 million , respectively. These investments consisted of privately-held equity securities without a readily determinable fair value and the Company has determined that it is not practicable to estimate the fair value of these investments. The Company has not tested these investments for impairment as there have not been any events or changes in circumstances that the Company believes would have had a significant adverse effect on the fair value of these investments. As of January 29, 2017 and January 31, 2016 , aggregate net investment accounted for under equity method of accounting was $2.0 million and $1.1 million , respectively, included in other assets.

Allowances Against Accounts Receivable

Accounts receivable are recorded at net realizable value or the amount that the Company expects to collect on gross customer trade receivables. The Company evaluates the collectability of its accounts receivable based on a combination of factors. The Company generally does not require collateral on accounts receivable as the majority of the Company’s customers are large, well-established companies. Historically, bad debt provisions have been consistent with management’s expectations. If the Company becomes aware of a customer’s inability to meet its financial obligations after a sale has occurred, it records an allowance to reduce the net receivable to the amount it reasonably believes it will be able to collect from the customer. For all other customers, the Company recognizes allowances for doubtful accounts based on the length of time the receivables are past due, the current business environment and historical experience. If the financial condition of the Company’s customers were to deteriorate or if economic conditions worsen, additional allowances may be required in the future. All of the Company’s accounts receivables are trade-related receivables.

The Company records a provision for estimated sales returns in the same period as the related revenues are recorded. These estimates are based on historical sales returns and other known factors. Actual returns could be different from our estimates and current provisions for sales returns and allowances, resulting in future charges to earnings. The portion of the estimate sales returns where there are outstanding receivables are recorded on the consolidated balance sheets as a reduction to accounts receivable.

The Company records a provision for sales rebates in the same period as the related revenues are recorded. These estimates are based on sales activity during the period. The actual rebate could be different from current provisions for sales rebates, resulting in future adjustments to earnings. The estimated sales rebates for sales for which there are no outstanding receivables are recorded on the consolidated balance sheets under the heading of "Accrued liabilities." The portion of the estimated sales rebate where there are outstanding receivables is recorded on the consolidated balance sheets as a reduction to accounts receivable.

A summary of allowances against accounts receivable for fiscal years ended January 29, 2017 and January 31, 2016 is as follows:



(in thousands)	January 29, 2017			January 31, 2016
Allowance for doubtful accounts	$	(2,696	)	$	(889	)
Sales rebate allowance	(2,571		)	(5,006		)
Sales return allowance	(1,795		)	(517		)
Other allowances	(1,168		)	(1,381		)
Total	$	(8,230	)	$	(7,793	)

Inventories

Inventories are stated at lower of cost or market and consist of materials, labor and overhead. The Company determines the cost of inventory by the first-in, first-out method. The Company evaluates inventories for excess quantities and obsolescence. This evaluation includes analysis of sales levels by product and projections of future demand. In order to state the inventory at lower of cost or market, the Company maintains reserves against its inventory. If future demand or market conditions are less favorable than the Company’s projections, a write-down of inventory may be required, and would be reflected in cost of goods sold in the period the revision is made.

Business Combinations

The Company accounts for business combinations at fair value. Goodwill is measured as the excess of consideration transferred over the acquisition date net fair values of the assets acquired and the liabilities assumed. All changes that do not qualify as measurement period adjustments are included in current period earnings. Significant judgment is required to determine the estimated fair value for assets and liabilities acquired and to assign their respective useful lives. The fair values assigned to tangible and intangible assets acquired and liabilities assumed, including contingent consideration, are based on management’s estimates and assumptions, as well as other information compiled by management, including available historical information and valuations that utilize customary valuation procedures and techniques.

The Company employs the income approach to estimate the fair value of intangible assets, which is based on forecasts of the expected future cash flows attributable to the respective assets. The fair value of acquired in-process research and development projects ("IPR&D") is determined using an income approach or replacement cost approach as applicable. The replacement cost approach is used for IPR&D projects that were considered long-term core investments and are not anticipated to be profitable for a period of time. IPR&D projects which are valued using an income approach, measured the returns attributable to each specific IPR&D project, discounted to present value using a risk-adjusted rate of return, including as appropriate, any tax benefits derived from amortizing the intangible assets for tax purposes. In determining significant estimates and assumptions inherent in the valuations, the Company considers the amount and timing of future cash flows (including expected growth rates and profitability), the underlying product life cycles, economic barriers to entry, a brand’s relative market position and the discount rate applied to the cash flows, among others.

If actual results differ from the estimates and judgments used in these estimates, the amounts recorded in the consolidated financial statements could result in a possible impairment of the intangible assets and goodwill, or require acceleration of the amortization expense of finite-lived intangible assets.

Variable Interest Entities

The Company is required to consolidate variable interest entities ("VIEs") in which it has a controlling financial interest in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 810, "Consolidation". A controlling financial interest will have both of the following characteristics: (i) the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, and (ii) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE.

The Company’s variable interest in VIEs may be in the form of equity ownership, contracts to purchase assets, management services, and development agreements between the Company and a VIE, loans provided by the Company to a VIE or other member, and/or guarantees provided by members to banks and other parties.

The Company analyzes its investments or other interests to determine whether it represents a variable interest in a VIE. If so, the Company evaluates the facts to determine whether it is the primary beneficiary. The Company considers itself to be the

primary beneficiary when it has both the power to direct activities of the VIE that most significantly impact the VIEs economic performance and the obligation to absorb losses from or the right to receive benefits of the VIE that could potentially be significant to the VIE. With regards to its investment in MultiPhy Ltd. ("MultiPhy"), the Company concluded that its equity interest represents a variable interest, but it is not the primary beneficiary as prescribed in ASC 810. Specifically, in reaching this conclusion, the Company considered the activities that most significantly drive profitability for MultiPhy and determined that the activity that most significantly drove profitability was related to the technology and related product road maps. The Company has a board observer role and thus concluded that it was not in a position of decision-making or other authority to influence MultiPhy’s activities that could be considered significant with respect to its operations, including research and development plans and changes to the product road map. There are currently no VIEs that are consolidated.

Derivatives and Hedging Activities

As required by ASC 815, the Company records all derivatives on the consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

In accordance with the FASB’s fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Depreciation is computed over the estimated useful lives of the related asset type or term of the operating lease using the straight-line method for financial statement purposes. Maintenance and repairs are charged to expense as incurred and the costs of additions and betterments that increase the useful lives of the assets are capitalized.

The estimated service lives for property, plant and equipment is as follows:



	Estimated
	Useful Lives
Buildings and leasehold improvements	7 to 39 years
Enterprise resource planning systems	13 years
Machinery and equipment	5 to 8 years
Transportation vehicles	5 years
Furniture and fixtures	7 years
Computers and computer software	3 years

Impairment of Goodwill, Other Intangible and Long-Lived Assets

Goodwill

Goodwill is the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. Goodwill is not amortized but is tested for impairment using either a qualitative assessment or a two-step method.

As part of the annual goodwill impairment test, the Company has the option to perform a qualitative assessment of a reporting unit's goodwill for impairment. If the Company chooses to perform a qualitative assessment and determines the fair value more likely than not exceeds the carrying value of a reporting unit, no further evaluation is necessary.

In conducting the qualitative assessment, the Company considers relevant events or circumstances that affect the fair value or carrying amount of a reporting unit. Examples of events and circumstances include macroeconomic conditions, industry and market considerations, overall financial performance, events affecting a reporting unit and capital markets pricing. We place

more weight on the events and circumstances that most affect the reporting unit’s fair value or the carrying amount of its net assets.

When the Company performs the two-step method, step one is the identification of potential impairment. The Company’s operating segments represent its reporting units since segment management, who report to the CODM, regularly review operating results and make resource allocation decisions at this level. This involves comparing the fair value of each reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds the carrying amount, the goodwill of the reporting unit is considered not impaired and the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the impairment test is performed to measure the amount of impairment loss, if any. The Company tests, by reporting unit, goodwill and other indefinite-lived intangible assets for impairment at November 30 or more frequently if it believes indicators of impairment exist or if it makes changes to a reporting unit with assigned goodwill.

For its two-step method annual impairment review, the Company primarily uses an income approach, which incorporates multi-period excess earnings present value techniques (discounted cash flows) as well as other generally accepted valuation methodologies to determine the fair value of the assets using Level 3 inputs. The Company's assumptions incorporate judgments as to the price received to sell a reporting unit as a whole in an orderly transaction between market participants at the measurement date. Considering the integration of its operations, the Company has assumed that the highest and best use of a reporting unit follows an “in-use” valuation premise.

Significant management judgment is required in determining the estimations of future cash flows, which is dependent on internal forecasts, the long-term rate of growth for the Company's business, the useful life over which cash flows will occur, and the weighted average cost of capital. The value of goodwill, could be impacted by future adverse changes such as: (i) any future declines in operating results, (ii) a decline in the valuation of technology company stocks, including the valuation of the Company's common stock, (iii) a significant slowdown in the worldwide economy and the semiconductor industry or (iv) any failure to meet the Company's performance projections included in its forecasts of future operating results.

Other Intangibles and Long-lived Assets

Finite-lived intangible assets resulting from business acquisitions or technology licenses purchased are amortized on a straight-line basis over their estimated useful lives. The useful lives of acquisition-related intangible assets represent the point where over 90% of realizable undiscounted cash flows for each intangible asset are recognized. The assigned useful lives are based upon the Company’s historical experience with similar technology and other intangible assets owned by the Company. The useful life of technology licenses is usually based on the term of the agreement.

IPR&D is recorded at fair value as of the date of acquisition as an indefinite-lived intangible asset until the completion or abandonment of the associated research and development efforts or impairment. Upon completion of development, acquired IPR&D assets are transferred to finite-lived intangible assets and amortized over their useful lives.

The Company reviews indefinite-lived intangible assets for impairment on an annual basis in conjunction with goodwill or whenever events or changes in circumstances indicate the carrying value may not be recoverable. Recoverability of indefinite-lived intangible assets is measured by comparing the carrying amount of the asset to the future discounted cash flows the asset is expected to generate. Also, the Company reassesses the estimated remaining useful lives of any impaired assets and adjusts accordingly estimates of future amortization expense related to these assets.

The Company assesses finite-lived intangibles and long-lived assets for impairment when indicators of impairment, such as reductions in demand or significant economic slowdowns in the semiconductor industry, are present. Reviews are performed to determine whether the carrying value of an asset is impaired, based on comparisons to undiscounted expected future cash flows. If this comparison indicates that there is impairment, the impaired asset is written down to fair value, which is typically calculated using: (i) quoted market prices and/or (ii) discounted expected future cash flows utilizing a discount rate. Impairment is based on the excess of the carrying amount over the fair value of those assets.

Functional Currency

The Company has concluded that the functional currency of all subsidiaries is the U.S. Dollar.

Fair Value Measurements

When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of

nonperformance. The Company uses the following three levels of inputs in determining the fair value of the Company’s assets and liabilities, focusing on the most observable inputs when available:

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

Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is disclosed is determined based on the lowest level input that is significant to the fair value measurement.

Revenue Recognition

The Company recognizes product revenue when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectability is probable. Recovery of costs associated with product design and engineering services are recognized during the period in which services are performed. The product design and engineering recovery, when recognized, will be reported as a reduction to product development and engineering expense. Historically, these recoveries have not exceeded the cost of the related development efforts.

The Company includes revenue related to granted technology licenses as part of "Net sales." Historically, revenue from these arrangements has not been significant though it is part of its recurring ordinary business.

The Company defers revenue recognition on shipment of products to certain customers, principally distributors, under agreements which provide for limited pricing credits or return privileges, until these products are sold through to end-users or the return privileges lapse. For sales subject to certain pricing credits or return privileges, the amount of future pricing credits or inventory returns cannot be reasonably estimated given the relatively long period in which a particular product may be held by the customer. Therefore, the Company has concluded that sales to customers under these agreements are not fixed and determinable at the date of the sale and revenue recognition has been deferred. The Company estimates the deferred gross margin on these sales by applying an average gross profit margin to the actual gross sales. The average gross profit margin is calculated for each operating segment which is expected to approximate actual costs at the date of sale. The estimated deferred gross margins on these sales, where there are no outstanding receivables, are recorded on the consolidated balance sheets under the heading of "Deferred revenue." There were no significant impairments of deferred cost of sales in fiscal years 2017 , 2016 or 2015 .

The Company records a provision for estimated sales returns in the same period as the related revenues are recorded. The Company bases these estimates on historical sales returns and other known factors. Actual returns could be different from Company estimates and current provisions for sales returns and allowances, resulting in future charges to earnings.

The Company records a provision for sales rebates in the same period as the related revenues are recorded. These estimates are based on sales activity during the period. Actual rebates given could be different from our estimates and current provisions for sales rebates, resulting in future charges to earnings.

The following table summarizes the deferred revenue balance:



(in thousands)	January 29, 2017			January 31, 2016
Deferred revenues	$	11,419		$	5,991
Deferred cost of revenues	(2,246		)	(1,139		)
Deferred revenue, net	9,173			4,852
Deferred product design and engineering recoveries	2,886			3,776
Total deferred revenue	$	12,059		$	8,628

Cost of Sales

Cost of sales includes materials, depreciation on fixed assets used in the manufacturing process, shipping costs, direct labor and overhead.

Sales and Marketing

The Company expenses sales and marketing costs, which include advertising costs, as they are incurred. Advertising costs were $0.4 million , $0.2 million and $0.1 million fo r fiscal years 2017 , 2016 and 2015 , respectively.

Product Development and Engineering

Product development and engineering costs are charged to expense as incurred. Recoveries from nonrecurring engineering services are recorded as an offset to product development expense incurred in support of this effort since these activities do not represent an earnings process core to the Company’s business and serve as a mechanism to partially recover development expenditures.

The Company received approximately $11.9 million , $21.1 million and $29.3 million in fiscal years 2017 , 2016 and 2015 , respectively for nonrecurring engineering services.

Income Taxes

The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts and their respective tax bases. The consolidated balance sheets include current and long term prepaid taxes under "Prepaid taxes" and "Other assets" and current and long term liabilities for uncertain tax positions under "Accrued liabilities" and "Other long-term liabilities."

As part of the process of preparing the Company’s consolidated financial statements, the Company estimates income taxes in each of the jurisdictions in which it operates. This process involves estimating the current tax liability together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities. The Company must assess the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent the Company believes that recovery is not likely, it must establish a valuation allowance. To the extent the Company changes its valuation allowance in a period, the change is generally recorded through the tax provision on the Consolidated Statements of Income.

The income tax effects of share-based compensation payments are recognized for financial reporting purposes only if such awards are expected to result in a tax deduction. The Company does not recognize a deferred tax asset for an excess tax benefit (that is, a tax benefit that exceeds the tax benefit for the amount of compensation cost recognized for the award for financial reporting purposes) that has not been realized. In determining when an excess tax benefit is realized, the Company has elected to follow the ordering provision of the tax law.

For intra-entity differences between the tax basis of an asset in the buyer’s tax jurisdiction and their cost as reported in the consolidated financial statements, the Company does not recognize a deferred tax asset. Income taxes paid on intra-entity profits on assets remaining within the group are accounted for as prepaid taxes. (See Note 13 for further discussion of income taxes).

Other Comprehensive (Loss) Income

Other comprehensive income includes unrealized gains and losses on available-for-sale investments, interest rate hedging activities and foreign currency translation adjustments. This information is provided in our Consolidated Statements of Comprehensive Income.

Share-Based Compensation

The Company has various equity award plans ("Plans") that provide for granting stock based awards to employees and non-employee directors of the Company. The Plans provide for the granting of several available forms of stock compensation. As of January 29, 2017 , the Company has granted non-qualified stock option awards ("NQSOs") and restricted stock unit awards ("RSUs") under the Plans and has also issued some share-based compensation outside of the Plans, including NQSOs and RSUs as inducements to join the Company.

Earnings per Share

The computation of basic and diluted earnings per common share was as follows:



	Fiscal Year Ended
(in thousands, except per share amounts)	January 29, 2017		January 31, 2016		January 25, 2015
Net income (loss)	$	54,661	$	11,497	$	27,947

Weighted average common shares outstanding - basic	65,427		65,657		67,108
Dilutive effect of share-based compensation	682		304		577
Weighted average common shares outstanding - diluted	66,109		65,961		67,685
Basic earnings (loss) per common share	$	0.84	$	0.18	$	0.42
Diluted earnings (loss) per common share	$	0.83	$	0.17	$	0.41
Anti-dilutive shares not included in the above calculations	1,111		2,569		1,714

Basic earnings per common share is computed by dividing income available to common stockholders by the weighted-average number of shares of common stock outstanding during the reporting period. Diluted earnings per common share incorporates the incremental shares issuable, calculated using the treasury stock method, upon the assumed exercise of NQSOs and the vesting of RSUs.

Contingencies

The Company accrues an undiscounted liability for contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated, and the Company discloses the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for our consolidated financial statements not to be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote.

Because litigation outcomes are inherently unpredictable, the Company’s evaluation of legal proceedings often involves a series of complex assessments by management about future events and can rely heavily on estimates and assumptions. If the assessments indicate that loss contingencies that could be material to any one of our consolidated financial statements are not probable, but are reasonably possible, or are probable, but cannot be estimated, then the Company discloses the nature of the loss contingencies, together with an estimate of the range of possible loss or a statement that such loss is not reasonably estimable.

The Company also records contingent earn-out liabilities which represent the Company’s requirement to make additional payments related to acquisitions based on certain performance targets achieved during the earn-out periods. For such earn-outs, the Company estimates the fair value based on probability assessments of achieving the specified performance targets.

Subsequent Events

The Company evaluates all events through the issuance date of the consolidated financial statements to determine whether any subsequent events have occurred that require recognition or disclosure.

Recent Accounting Pronouncements

In January 2017, the FASB issued Accounting Standards Update ("ASU") No. 2017-04, Intangibles-Goodwill and Other (Topic 350). The pronouncement was issued to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. This pronouncement stipulates that an entity should perform a goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and will recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, with the loss recognized not exceeding the total amount of goodwill allocated to that reporting unit. The amendments in this pronouncement are to be applied on a prospective basis. This guidance will be effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 31, 2017. The Company’s current year qualitative assessment and prior year Step 1 test outcomes indicated that the adoption of this pronouncement is not expected to have a material impact on the Company’s consolidated financial statements.

In October 24, 2016, the FASB issued ASU No. 2016-16, Intra-Entity Asset Transfers Other Than Inventory (Topic 740). This accounting standard update is aimed at recognizing the income tax consequences of intra-entity transfers of assets other than inventory when they occur. This removes the exception to postpone recognition until the asset has been sold to an outside party.

This ASU will be effective in the first quarter of fiscal year 2020. The standard update is required to be applied on a modified retrospective basis through a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The Company is currently assessing the impact this pronouncement will have on its consolidated financial statements.

In August 26, 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (Topic 230). The primary purpose of this ASU is to reduce the diversity in practice that has resulted from the lack of consistent principles on this topic. This ASU is effective for fiscal years beginning after December 15, 2017. This ASU will be effective for the Company as of the beginning of fiscal year 2019. Early adoption is permitted in any interim or annual period. The Company is continuing to assess the overall impacts of the new standard. The Company does not expect the adoption of this pronouncement to have a material impact on its consolidated financial statements.

In March 2016, FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718). This account standard involves several aspects of accounting for share-based payment transactions, including the income tax effects, statutory withholding requirements, forfeitures, and classification on the statement of cash flows. The amendments in this pronouncement are effective for fiscal years beginning after December 15, 2016, including interim periods within that fiscal year. Under this ASU, share-based compensation excess benefits (if any) will be recorded to the Consolidated Statements of Income. The Company is required to adopt the amendments in the first quarter of fiscal year 2018. The Company receives a limited tax benefit from its equity program, hence, does not expect the adoption of this pronouncement to have a material impact on its consolidated financial statements.

In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842), which will require that substantially all leases be recognized by lessees on their consolidated balance sheets as a right-of-use asset and corresponding lease liability, including leases currently accounted for as operating leases. The new standard also will result in enhanced quantitative and qualitative disclosures, including significant judgments made by management, to provide greater insight into the extent of expense recognized and expected to be recognized from existing leases. The standard requires modified retrospective adoption and will be effective December 15, 2018, with early adoption permitted. The Company expects the valuation of right of use assets and lease liabilities, previously described as operating leases, to be the present value of our forecasted future lease commitments. The Company is continuing to assess the overall impacts of the new standard, including the discount rate to be applied in these valuations.

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330) Related to Simplifying the Measurement of Inventory which will apply to all inventory except inventory that is measured using last-in, first-out ("LIFO") or the retail inventory method. Inventory measured using first-in, first-out or average cost is covered by the new amendments. Inventory within the scope of the new guidance should be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using LIFO or the retail inventory method. The amendments will take effect for public business entities for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The new guidance should be applied prospectively, and earlier application is permitted as of the beginning of an interim or annual reporting period. The Company does not expect the adoption of this pronouncement to have a material impact on its consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which will require an entity to recognize revenue from 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 for those goods or services. The guidance addresses, in particular, contracts with more than one performance obligation, as well as the accounting for some costs to obtain or fulfill a contract with a customer, and provides for additional disclosures with respect to revenues and cash flows arising from contracts with customers. Public entities are required to apply the amendments on either a full- or modified-retrospective basis for annual periods beginning after December 15, 2017 and for interim periods within those annual periods. This update will be effective for the Company beginning in the first quarter of fiscal year 2019. Early adoption is not permitted. The Company plans to adopt the standard retrospectively with the cumulative effect of initially applying it recognized at the date of initial application ("modified retrospective" approach).

The Company’s assessment has identified a change in revenue recognition timing on our component sales made to distributors. The Company expects to recognize revenue when the Company delivers to the distributor rather than deferring recognition until the distributor sells the components.

On the date of initial application, the Company will remove the deferred net revenue on component sales made to distributors through a cumulative adjustment to retained earnings. The Company expects the revenue deferral to be offset by the acceleration of revenue recognition as control of the product transfers to its customer.

The Company will continue to track relevant elements and finalize its evaluation of any changes to its accounting policies and disclosures.

Note 3 : Acquisitions

Triune Systems, L.L.C

On March 4, 2015 the Company acquired Triune Systems, L.L.C. ("Triune"), a privately-held supplier of isolated switching, wireless charging and power management platforms targeted at, among other things, high and low power, high efficiency applications. Under the terms of the purchase agreement, the Company acquired all of the outstanding equity interest in Triune for a guaranteed minimum purchase price of $45.0 million consisting of $35.0 million in cash paid at closing, with an additional cash consideration of $10.0 million of which $9.5 million was paid in September 2015 and $0.5 million was paid in the second quarter of fiscal year 2017. In March 2015, the Company borrowed $35.0 million under its revolving line of credit in connection with this acquisition (see Note 10 for discussion regarding Credit Facilities).

Subject to achieving certain future financial goals ("Triune Earn-out"), up to $70.0 million of contingent consideration will be paid over three years if certain revenue targets are achieved in each of the fiscal years 2016 through 2018. An additional payment of up to $16.0 million will be paid after fiscal year 2018 if certain cumulative revenue and operating income targets are achieved.

The Triune Earn-out targets for fiscal year 2017 were not met and the Company does not expect the fiscal year 2018 targets to be achieved. The fair value of the Triune Earn-out liability was zero as of January 29, 2017 . (See Notes 5 and 14 ).

The Triune business meets the definition of a business and is accounted for under the acquisition method of accounting in accordance with the FASB’s ASC Topic 805, Business Combinations. The purchase price allocation for the Triune acquisition was finalized in the second quarter of fiscal year 2016. Total acquisition consideration has been allocated to the acquired tangible and intangible assets and assumed liabilities of Triune based on their respective estimated fair values as of the acquisition date. Acquisition-related transaction costs are not included as a component of consideration transferred, but are accounted for as an expense in the period in which the costs are incurred. Any excess of the acquisition consideration over the fair value of the assets acquired and liabilities assumed has been allocated to goodwill. The goodwill resulted from expected synergies from the transaction, including complementary products that will enhance the Company’s overall product portfolio, and opportunities within new markets. The Company expects that $16.1 million of goodwill will be deductible for tax purposes.

The Company’s allocation of the total purchase price for Triune is summarized below:



(in thousands)	At March 4, 2015
Current assets	$	877
Property, plant, and equipment, net	226
Amortizable intangible assets	12,000
Goodwill	49,384
Current liabilities	(1,287		)
Earn-out liability	(16,200		)
Total acquisition consideration	$	45,000

Triune’s technology complemented the portfolio of products offered in the Company’s legacy Power and High-Reliability Products Group. The Company concluded that the Triune and legacy Power and High-Reliability components should be aggregated and deemed a single reporting unit after considering similarities among different economic characteristics such as concentration of key customers, unit selling price decreases, increased competitors due to market expansion and chain of command of the newly acquired business.

Net revenues and earnings attributable to Triune since the acquisition date were not material. Pro forma operating results have not been presented as Triune’s annual operating results have not been material to the Company’s consolidated financial results.

EnVerv, Inc.

On January 13, 2015 , the Company paid $4.9 million to acquire select assets from EnVerv, Inc. , a privately-held supplier of power line communications ("PLC") and Smart Grid solutions targeted at advanced metering infrastructure, home energy management systems and IoT applications. The Company has concluded that the acquired assets constituted a business and accordingly accounted for this transaction as a business combination.

The purchase price allocation for the EnVerv asset acquisition was finalized in the first quarter of fiscal year 2016. Total acquisition consideration has been allocated to the acquired tangible and intangible assets and assumed liabilities based on their respective estimated fair values as of the acquisition date. The excess of the acquisition consideration over the fair value of assets acquired and liabilities assumed has been allocated to goodwill. As of January 25, 2015, $1.4 million of the total acquisition consideration has been allocated to core technologies and $3.4 million has been allocated to goodwill. The remaining balance has been allocated to acquired tangible assets and assumed liabilities. The Company expects that all such goodwill will be deductible for tax purposes.

Net revenues and earnings attributable to EnVerv since the acquisition date have not been material.

Note 4 : Investments

Cash and cash equivalents includes investments in money market funds that are valued based on the net asset value of the funds. The cash equivalents consist primarily of money market funds that are Level 1 measurements. The investments in these funds were $16.9 million for the fiscal years ended January 29, 2017 and January 31, 2016 .

The following table summarizes the Company’s available-for-sale securities:



	January 29, 2017						January 31, 2016
(in thousands)	Market Value		Adjusted Cost		Gross Unrealized Gain		Market Value		Adjusted Cost		Gross Unrealized Gain
Convertible debt	$	1,425	$	1,425	$	—	$	—	$	—	$	—
Total other assets	$	1,425	$	1,425	$	—	$	—	$	—	$	—

Within 1 year	$	1,425	$	1,425	$	—	$	—
After 1 year through 5 years	—		—		—		—
Total investments	$	1,425	$	1,425	$	—	$	—

Unrealized gains and losses are the result of fluctuations in the market value of the Company’s available-for-sale securities and are included in “Accumulated other comprehensive income” within the consolidated balance sheets. For all periods presented, there were no unrealized gains or losses on the Company's available-for-sale securities.

The Company's available-for-sales securities consist of an investment in a convertible debt instruments issued by a privately-held company and has been included in "Other assets" within the consolidated balance sheets.

The Company currently has a $21.0 million investment in a private entity, which includes $5.0 million of restricted deposit that is accounted for at cost, and included in "Other assets" within the consolidated balance sheets. As part of its investment, the Company received a call option that allows the Company to purchase all of the outstanding equity of the entity. The call option, which was out of the money at inception, is exercisable until June 30, 2018.

Note 5 : Fair Value Measurements

Instruments Measured at Fair Value on a Recurring Basis

Financial assets and liabilities measured and recorded at fair value on a recurring basis were presented within the Company's consolidated balance sheets as follows:



	Fair Value as of January 29, 2017								Fair Value as of January 31, 2016
(in thousands)	Total		(Level 1)		(Level 2)		(Level 3)		Total		(Level 1)		(Level 2)		(Level 3)
Financial assets:
Cash equivalents	$	16,945	$	16,945	$	—	$	—	$	16,866	$	16,866	$	—	$	—
Derivative financial instruments	326		—		326		—		—		—		—		—

Total financial assets	$	18,696	$	16,945	$	326	$	1,425	$	16,866	$	16,866	$	—	$	—

Financial liabilities:
Triune Earn-out	$	—	$	—	$	—	$	—	$	—	$	—	$	—	$	—
Cycleo Earn-out	1,242		—		—		1,242		1,457		—		—		1,457
Derivative financial instruments	—		—		—		—		—		—		—		—
Total financial liabilities	$	1,242	$	—	$	—	$	1,242	$	1,457	$	—	$	—	$	1,457

During fiscal years 2017 and 2016 , the Company had no transfers of financial assets or liabilities between Level 1, Level 2 or Level 3. As of January 29, 2017 and January 31, 2016 , the Company had not elected the fair value option for any financial assets and liabilities for which such an election would have been permitted.

The fair values of the foreign exchange forward contracts are valued using Level 2 inputs. Foreign currency forward contracts are valued using readily available foreign currency forward and interest rate curves. The fair value of each contract is determined by comparing the contract rate to the forward rate and discounting to the present value. Contracts in a gain position are recorded in the consolidated balance sheets under the caption "Other current assets” and the value of contracts in a loss position are recorded under the caption "Accrued liabilities” within the consolidated balance sheets. Please see Note 19 for further discussion of the Company’s derivative instruments.

The convertible debt is valued using probability weighted cash flows (Level 3 inputs).

The Triune Earn-out liability is valued utilizing estimates of annual revenue and operating income (Level 3 inputs) during a period ending January 2018. These estimates represent inputs for which market data are not available and are developed using the best information available about the assumptions that market participants would use when pricing the liability.

The Cycleo Earn-out liability (see Note 14 ) is valued utilizing estimates of annual revenue and operating income (Level 3 inputs) through April 2020. These estimates represent inputs for which market data are not available and are developed using the best information available about the assumptions that market participants would use when pricing the liability.

The Company measures contingent earn-out liabilities at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The Company uses a Monte Carlo valuation method as a valuation technique to determine the value of the earn-out liability. The significant unobservable inputs used in the fair value measurements are revenue projections over the earn-out period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs in isolation would result in a significantly higher or lower liability, with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount paid, and the difference between the fair value estimate and amount paid will be recorded in earnings. For both the Triune Earn-out and Cycleo Earn-out, these companies have business profiles comparable to a start-up company. Accordingly, their respective revenue projections are subject to significant revisions. This characteristic has resulted in volatile changes to the measurement of fair value of the Triune Earn-out since the time of the Triune acquisition.

The Company reviews and re-assesses the estimated fair value of contingent consideration on a quarterly basis, and the updated fair value could differ materially from the previous estimates. Changes in the estimated fair value of the Company’s contingent earn-out liabilities related to the time component of the present value calculation are reported in "Interest expense” within the

Consolidated Statements of Income. Adjustments to the estimated fair value related to changes in all other unobservable inputs are reported in operating income.

A reconciliation of the change in the earn-out liability during the fiscal year ended January 29, 2017 is as follows:



(in thousands)	Cycleo			Triune		Total
Balance at January 31, 2016	$	1,457		$	—	$	1,457
Changes in fair value of contingent earn-out obligations	(215		)	—		(215		)
Balance as of January 29, 2017	$	1,242		$	—	$	1,242

Instruments Not Recorded at Fair Value on a Recurring Basis

Some of the Company’s financial instruments are not measured at fair value on a recurring basis but are recorded at amounts that approximate fair value due to their liquid or short-term nature. Such financial assets and financial liabilities include: cash and cash equivalents, net receivables, certain other assets, accounts payable, accrued expenses, accrued personnel costs, and other current liabilities.

The Company’s long-term debt is not recorded at fair value on a recurring basis, but is measured at fair value for disclosure purposes. The fair value of the Company’s Term Loans (as defined in Note 10 ) is $146.3 million and Revolving Commitments (as defined in Note 10 ) is $97.0 million at January 29, 2017 both of which are based on Level 2 inputs which are derived from transactions with similar amounts, maturities, credit ratings and payment terms.

Assets and Liabilities Recorded at Fair Value on a Non-Recurring Basis

The Company reduces the carrying amounts of its goodwill, intangible assets, long-lived assets and non-marketable equity securities to fair value when held for sale or determined to be impaired.

For its investment in non-marketable equity interests, the Company has not identified events or changes in circumstances that may have a significant adverse effect on the fair value of its equity investments during fiscal year 2017 .

Note 6 : Inventories

Inventories, consisting of material, material overhead, labor, and manufacturing overhead, are stated at the lower of cost (first-in, first-out) or market and consist of the following:



(in thousands)	January 29, 2017		January 31, 2016
Raw materials	$	2,968	$	2,094
Work in progress	44,740		40,940
Finished goods	18,164		20,841
Inventories	$	65,872	$	63,875

Note 7 : Property, Plant and Equipment

The following is a summary of property and equipment, at cost less accumulated depreciation:



(in thousands)	January 29, 2017			January 31, 2016
Property	$	11,314		$	8,888
Buildings	30,294			18,749
Leasehold improvements	9,566			10,182
Machinery and equipment	150,276			141,357
Enterprise resource planning systems	28,166			28,166
Furniture and office equipment	35,025			35,907
Construction in progress	5,505			1,539
Property, plant and equipment, gross	270,146			244,788
Less accumulated depreciation and amortization	(161,236		)	(143,782		)
Property, plant and equipment, net	$	108,910		$	101,006

As of January 29, 2017 and January 31, 2016 , construction in progress consists primarily of machinery and equipment awaiting completion of installation and being placed in service.

During the fiscal year ended January 29, 2017 and January 31, 2016 , the Company did not record significant impairment charges.

During the fiscal year ended January 25, 2015, the Company recorded impairment charges against certain property, plant and equipment assets as a result of its strategic decision to reduce its investment in the defense and microwave communications infrastructure market and further reduce its investment in the optical long-haul markets. These impairment charges relate primarily to limited sales volumes through the remaining life of the assets. In determining the amount of impairment, the Company used a sales comparison method and cost approach to estimate the fair value of property, plant and equipment, and an income approach to estimate the fair value of intangible assets. The Company concluded that the Systems Innovation Group is the asset group for impairment testing purposes. The categorization and classification of these charges, recorded in fiscal year 2015, are summarized below:



(in thousands)	Machinery and equipment		Furniture and office equipment		Leasehold improvements		Total
Cost of sales	$	2,799	$	10	$	1	$	2,810
Product development and engineering	3,477		33		—		3,510
Selling, general and administrative expenses	5		—		1		6
Total impairment charge	$	6,281	$	43	$	2	$	6,326

Depreciation expense was $21.7 million , $23.2 million , and $21.1 million in fiscal years 2017 , 2016 , and 2015 , respectively.

Note 8 : Goodwill and Intangible Assets

Goodwill – There were no changes in the carrying amount of goodwill during fiscal years 2017 and 2016 . Goodwill by applicable reporting unit is as follows:



(in thousands)	Signal Integrity		Power and High-Reliability		Wireless and Sensing		Total
Balance at January 31, 2016	$	261,891	$	49,384	$	18,428	$	329,703
Additions	—		—		—		—
Balance at January 29, 2017	$	261,891	$	49,384	$	18,428	$	329,703

Goodwill is not amortized, but is tested for impairment using either a qualitative assessment or a two-step method on an annual basis and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The recoverability of goodwill is measured at the reporting unit level by comparing the reporting unit’s carrying amount, including goodwill, to the fair market value of the reporting unit.

Goodwill is allocated to three reporting units (Signal Integrity, Power and High-Reliability and Wireless and Sensing) (see Note 16 ). The difference between the fair value and the carrying amount of these reporting units is one of several factors the Company will consider before reaching its conclusion about whether to perform the first step of the goodwill impairment test.

Goodwill was tested for impairment at the reporting unit level as of November 30, 2016 and November 30, 2015 , the dates of the Company’s annual impairment review for fiscal years 2017 and 2016 , respectively.

For fiscal year 2017, the Company performed a qualitative assessment and concluded that it was more likely than not that the fair value of each of the three reporting units exceeded its carrying value. As such, the Company did not perform a quantitative impairment analysis.

For fiscal year 2016, the Company performed the first step quantitative analysis of the goodwill impairment test. The Company estimated the fair values using an income approach. The cash flows for each reporting unit were based on discrete financial forecasts developed by management for planning purposes. Cash flows beyond the discrete forecasts were estimated using a terminal value calculation, which incorporated historical and forecasted financial trends for each identified reporting unit and considered perpetual earnings growth rates for publicly traded peer companies. Specifically, the income approach valuations included the following assumptions:



	November 30, 2015
Discount rate	11.0% - 24.0%
Perpetual growth rate	3.0%
Tax rate	13.5% - 40.0%
Risk-free rate	2.6%
Peer company beta	1.2 - 1.9

In addition to its annual review, the Company performs a test of impairment when indicators of impairment are present. As of January 29, 2017 and January 31, 2016 , there were no indications of impairment of the Company's goodwill balances.

Purchased Intangibles - The following table sets forth the Company’s finite-lived intangible assets resulting from business acquisitions and technology licenses purchased, which continue to be amortized:



		January 29, 2017							January 31, 2016
(in thousands)	Estimated Useful Life	Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount
Core technologies	5-8 years	$	144,930	$	(92,940	)	$	51,990	$	148,210	$	(74,005	)	$	74,205
Customer relationships	5-10 years	30,030		(20,247		)	9,783		30,030		(15,847		)	14,183
Technology licenses ⁽¹⁾	2 years	100		(100		)	—		100		(58		)	42
Total finite-lived intangible assets		$	175,060	$	(113,287	)	$	61,773	$	178,340	$	(89,910	)	$	88,430


(1)	Technology licenses relate to licensing agreements entered into by the Company that are used in research and development activities and have alternative future uses. Amortization expense related to technology licenses is reported as "Product development and engineering" in the Consolidated Statements of Income.

The Company reviews finite-lived intangible assets for impairment when there are indicators of impairment, by comparing the carrying amount of the asset to the future discounted cash flows that asset is expected to generate. In December 2014, certain intangible assets relating to the Systems Innovation reporting unit were determined to be impaired as a result of the Company's strategic decision to reduce its investment in the defense and microwave communications markets and its additional reductions in the long-haul optical market.

Impairments for technology licenses are included in "Product development and engineering" on the Consolidated Statements of Income. The impairment of core technologies and customer relationships is included in "Intangible asset impairments" on the Consolidated Statements of Income. Impairment charges for these items, which resulted in a new basis for the affected intangible assets, are included in the Consolidated Statements of Income as follows:

Note 10 : Credit Facilities

On November 15, 2016 (the "Closing Date"), Semtech Corporation, with certain of its domestic subsidiaries as guarantors (the "Guarantors"), entered into the amended and restated credit facility with the lenders party thereto ("Lenders"), and HSBC Bank USA, National Association, as administrative agent and as swing line lender and letter of credit issuer. The amended and restated credit facility amended and restated the prior credit agreement. The Company accounted for the amended and restated credit facility as a debt modification. Pursuant to the amended and restated credit facility, the Lenders provided the Company with senior secured first lien credit facilities in an aggregate principal amount of $400.0 million , consisting of term loans in an aggregate initial principal amount of $150.0 million ("Term Loans") and revolving commitments in an aggregate principal amount of $250.0 million ("Revolving Commitments"). Up to $40.0 million of the revolving commitments may be used to obtain letters of credit, up to $25.0 million of the revolving commitments may be used to obtain swing line loans, and up to $40.0 million of the revolving commitments may be used to obtain revolving loans and letters of credit in certain currencies other than U.S. Dollars. Each of the term loans and the revolving commitments is scheduled to mature on November 12, 2021 . As of January 29, 2017 , there were no amounts outstanding under the letters of credit, swing line loans and alternative currency sub-facilities.

All of the proceeds of the amended and restated credit facility were used to repay in full all of the obligations outstanding under the Company’s prior credit facility and to pay transaction costs in connection with such refinancing. As of November 15, 2016, $247.0 million of borrowings were outstanding under the amended and restated credit facility, consisting of $150.0 million in term loans and $97.0 million in revolving loans, and there was $153.0 million of undrawn revolving commitments. The proceeds of the revolving credit facility may be used by the Company for capital expenditures, permitted acquisitions, permitted dividends, working capital and general corporate purposes.

The amended and restated credit facility provides that, subject to certain conditions, the Company may request the establishment of one or more additional term loan facilities and/or increases to the revolving commitments in an aggregate principal amount not to exceed the sum of (a) $150.0 million and (b) the aggregate principal amount of all voluntary prepayments of term loans made prior to the date of incurrence of such additional term loan facilities and/or increases to the revolving commitments. The Lenders will have an opportunity to, but are not required to participate in the additional term loan facilities and/or revolving commitment increases. If the Lenders do not agree to provide such incremental facilities, the Company may request such additional and/or increased facilities from additional lenders.

Interest on loans made under the amended and restated credit facility in U.S. Dollars accrues, at the Company's option, at a rate per annum equal to (1) the Base Rate (as defined below) plus a margin ranging from 0.25% to 1.25% depending upon the Company’s consolidated leverage ratio or (2) LIBOR (determined with respect to deposits in U.S. Dollars) for an interest period to be selected by the Company plus a margin ranging from 1.25% to 2.25% depending upon the Company's consolidated leverage ratio (such margin, the "Applicable Margin"). The initial interest margin will be 2.00% for Base Rate loans and 1.00% for LIBOR rate loans, applicable until 2 business days following delivery of a compliance certificate by Semtech to the administrative agent with respect to the first fiscal period ending after the Closing Date. The "Base Rate" is equal to a fluctuating rate equal to the highest of (a) the prime rate of the administrative agent, (b) ½ of 1% above the federal funds effective rate published by the Federal Reserve Bank of New York and (c) one-month LIBOR (determined with respect to deposits in U.S. Dollars) plus 1.00% . Interest on loans made under the amended and restated credit facility in alternative currencies accrues at a rate per annum equal to LIBOR (determined with respect to deposits in the applicable alternative currency) (other than loans made in Canadian Dollars, for which a special reference rate for Canadian Dollars applies) for an interest period to be selected by the Company plus the Applicable Margin.

Commitment fees on the unused portion of the revolving commitments accrue at a rate per annum ranging from 0.20% to 0.45% depending upon the Company's consolidated leverage ratio, provided the initial commitment fee shall be 0.40% per annum, applicable until two business days following delivery of a compliance certificate by the Company to the administrative agent with respect to the first fiscal period ending after the Closing Date. With respect to letters of credit, the Company will pay the administrative agent, for the account of the lenders under the revolving credit facility, letter of credit participation fees at a rate per annum equal to the applicable margin then in effect with respect to LIBOR-based loans under the revolving commitments on the face amount of all outstanding letters of credit. The Company also will pay HSBC Bank USA, N.A., as the issuing bank, a fronting fee for each letter of credit issued under the amended and restated credit facility at a rate equal to 0.125% per annum based on the maximum amount available to be drawn under each such letter of credit, as well as its customary documentation fees.

All obligations of the Company under the amended and restated credit facility are unconditionally guaranteed by each of the Guarantors, which currently consist of all of the direct and indirect domestic subsidiaries of Semtech Corporation. Semtech

Corporation and the Guarantors have also pledged substantially all of their assets to secure their obligations under the amended and restated credit facility, including the Company's owned real property located in Camarillo, California.

The outstanding principal balance of the term loans will be subject to repayment in quarterly installments. No amortization is required with respect to the revolving credit facility. The Company may voluntarily prepay borrowings under the amended and restated credit facility at any time and from time to time, without premium or penalty, other than customary "breakage costs" and fees for LIBOR-based loans.

The term loans must be mandatorily prepaid using the proceeds of certain dispositions of assets and receipt of insurance proceeds, subject to agreed-upon thresholds and exceptions and customary reinvestment rights.

The amended and restated credit facility contains customary covenants, including limitations on Company’s ability to, among other things, incur indebtedness, create liens on assets, engage in certain fundamental corporate changes, make investments, sell or otherwise dispose of assets, repurchase stock, pay dividends or make similar distributions, engage in certain transactions with affiliates and make capital expenditures. In addition, the Company must comply with the following financial covenants, tested at the end of each fiscal quarter on a trailing four-quarter basis: (i) a minimum consolidated interest coverage ratio of 3.00 to 1.00 and (ii) a maximum consolidated leverage ratio of 3.00 to 1.00 provided that, such maximum consolidated leverage ratio may be increased to 3.25 to 1.00 or 3.50 to 1.00, as applicable, for the four consecutive fiscal quarters ending on or after the date of consummation of a permitted acquisition which constitutes a "Material Acquisition" under the amended and restated credit facility, subject to the satisfaction of certain conditions.

The amended and restated credit facility also contains customary provisions pertaining to events of default. If any event of default occurs, the principal, interest, and any other monetary obligations on all the then outstanding amounts can become due and payable immediately by action of the administrative agent acting upon the instructions of or with the consent of the Lenders representing more than 50% of the revolving commitments and outstanding term loans or automatically upon the occurrence of certain bankruptcy events related to the Company.

As of January 29, 2017 , the interest rate payable on both the Term Loans and the Revolving Commitments was 2.65% .

Scheduled maturities of current and long-term Term Loans are as follows:

The Company hasn't realized any tax benefits from stock option exercise activity for fiscal years 2017 , 2016 and 2015 because of taxable losses in the United States ("U.S.").

Grant Date Fair Values and Underlying Assumptions:

The Company uses the Black-Scholes pricing model to value stock options. The estimated fair value of restricted stock units, for which vesting is not linked to a market condition, is calculated based on the market price of the Company’s common stock on the date of grant. For restricted stock units that vest according to a market condition, the Company uses a Monte Carlo simulation model to value the award.

The following table summarizes the assumptions used in the Black-Scholes model to determine the fair value of stock options granted in fiscal years 2017 , 2016 and 2015 :



	Fiscal Year Ended
	January 29, 2017	January 31, 2016	January 25, 2015
Expected lives, in years	4.1 - 4.5	4.2 - 4.3	3.0 - 4.4
Estimated volatility	31% - 32%	29% - 32%	33% - 40%
Dividend yield	—	—	—
Risk-free interest rate	1.04% - 1.51%	1.24% - 1.49%	0.74% - 1.47%
Weighted average fair value on grant date	$5.71	$6.08	$7.18

The assumptions used in the Black-Scholes option pricing model were determined as follows:


•	Fair Value of Common Stock - The closing price on the date of the grant.


•	Expected Term - The expected term represents the period that our stock-based awards are expected to be outstanding.


•	Expected Volatility - The expected volatility was derived from the annualized volatility of the Company's closing stock price over the preceding three or four years depending upon the life of the option award.


•	Risk-Free Interest Rate - The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero-coupon U.S. Treasury notes with maturities approximately equal to the expected term of the stock option grants.


•	Dividend Rate - We have never declared or paid any cash dividends and do not plan to pay cash dividends in the foreseeable future, and, therefore, use an expected dividend yield of zero .

Stock Options . The Company has historically granted non-qualified stock options to both employees and non-employee directors. The fair value of these grants was measured on the grant date. The grant date for these awards is equal to the measurement date. These awards are valued as of the measurement date and recognized as an expense over the requisite vesting period (typically 3 - 4 years). The number of shares authorized per the equity incentive plan is 14,832,355 . The maximum contractual term of equity share options is ten years .

The following table summarizes the activity for stock options for fiscal years 2017 :



(in thousands, except for per share amounts)	Number of Shares		Weighted Average Exercise Price (per share)		Aggregate Intrinsic Value ⁽¹⁾		Number of Shares Exercisable	Weighted Average Contractual Term (years)
Balance at January 31, 2016	1,507		25.18		962		775

(1) The aggregate intrinsic value of stock options vested and exercisable and vested and expected to vest as of January 29, 2017 is calculated based on the difference between the exercise price and the closing price $33.70 of the Company's common stock on January 27, 2017.

Performance-Based Units . The Company grants performance-based restricted stock units to select employees. These awards have a performance condition in addition to a service condition. The performance metrics are determined based on a pre-defined cumulative three -year performance of the Company’s revenue and non-GAAP operating income measured against internal goals. The performance award which is granted in any fiscal year will be tied to the Company’s performance of that fiscal year and the succeeding two fiscal years. The performance award recipients must be employed for the entire three-year period, which is the explicit service and requisite service period, and be an active employee at the time of vesting of the awards (cliff vesting at the end of the third year). Under the terms of these awards, assuming the highest performance level of 200% with no cancellations due to forfeitures, the maximum number of shares that can be earned would be 378,000 shares and an additional 378,000 shares would be settled in cash. The Company would have a liability accrued under "Other liabilities" within the consolidated balance sheets equal to the value of 378,000 shares on the settlement date, which would be settled in cash. Only cash performance-based restricted stock unit awards are classified as liabilities and the value of these awards is re-measured at each reporting date. At January 29, 2017 , the performance metrics associated with the outstanding awards issued in fiscal years 2017 and 2016 are expected to be met at a level which would result in a grant at 190% and 0% of target, respectively. The awards for fiscal year 2014 did not meet the required performance level and were cancelled.

The performance-based restricted stock units are valued as of the measurement date and expense is recognized on a straight line basis for the awards expected to vest based on the probability of attainment of the performance condition for each separately vesting portion of the award.

The following table summarizes the activity for performance-based restricted stock units for fiscal years 2017 and 2016 :



			Subject to Share Settlement		Subject to Cash Settlement				Weighted Average Grant Date		Aggregate		Period Over Which Expected

The liability associated with performance-based restricted stock units decreased by $1.4 million in fiscal year 2017 due to the re-measurement adjustments and changes in the expected performance results.

Market Performance Restricted Stock Units. On February 26, 2014, the Company granted its CEO restricted stock units with a market performance condition. The award is eligible to vest during the period commencing February 26, 2014 and ending February 26, 2019 (the "Performance Period") as follows: 30% of the restricted stock units covered by the award will vest if, during any consecutive 120 calendar day period that commences and ends during the Performance Period, the average per-share closing price of the Company’s common stock equals or exceeds $35.00 ("Tranche 1") and the award will vest in full if, during any consecutive 120 calendar day period that commences and ends during the Performance Period, the average per-share closing price of the Company’s common stock equals or exceeds $40.00 ("Tranche 2"). The award will also vest if a majority change in control of the Company occurs during the Performance Period and, in connection with such event, the Company’s stockholders become entitled to receive per-share consideration having a value equal to or greater than $40.00 . The fair value of the awards was determined to be $17.26 and $14.88 for Tranche 1 and Tranche 2, respectively, on the grant date by application of the Monte Carlo simulation model.

The following tables summarize the assumptions used in the Monte Carlo simulation model to determine the fair value of restricted stock units granted in fiscal year 2015 for both Tranche 1 and Tranche 2.

Restricted Stock Units, Employees . The Company grants restricted stock units to employees which are expected to be settled with shares of the Company's common stock. The grant date for these awards is equal to the measurement date. These awards are valued as of the measurement date and recognized as an expense over the requisite vesting period (typically 4 years).

(1)	Includes 189,000 of restricted stock unit awards that will be cash settled and 196,000 of awards that will be settled in shares.

Restricted Stock Units, Cash-Settled, Non-Employee Directors . The Company maintains a compensation program pursuant to which restricted stock units are granted to the Company’s directors that are not employed by the Company or any of its subsidiaries. In June 2015, the Company changed its director compensation program so that a portion of the stock units granted under the program would be settled in cash and a portion would be settled in shares of the Company's common stock. Restricted stock units awarded under the program are scheduled to vest on the earlier of (i) one year after the grant date or (ii) the day immediately preceding the annual meeting of shareholders in the year following the grant. The portion of a restricted stock unit award under the program that is to be settled in cash will, subject to vesting, be settled when the director who received the award separates from the board of directors. The portion of a restricted stock unit award under the program that is to be settled in shares of stock will, subject to vesting, be settled promptly following vesting. There were no changes to the terms and conditions of the existing awards.

The restricted stock units that are to be settled in cash are accounted for as liabilities. Because these awards are not typically settled until a non-employee director’s separation from service, the value of these awards is re-measured at the end of each reporting period until settlement.

As of January 29, 2017 , the total number of vested but unsettled restricted stock units for non-employee directors is 173,657 . As of January 29, 2017 , $6.3 million of the liability associated with these awards is included in "Other long-term liabilities" within the consolidated balance sheets.

Restricted Stock Units, Stock Settled, Non-Employee Directors. As a result of the June 2015 changes to the Company’s director compensation program, beginning in July 2015, the Company began granting new restricted stock units to non-employee Directors which are expected to be settled with shares of the Company's common stock at the time of vesting. The grant date for these awards is equal to the measurement date. These awards are valued as of the measurement date and recognized as an expense over the requisite vesting period (typically one year ).

Modification of Awards. On December 19, 2014 and August 17, 2015, the Company modified the equity awards of certain executive officers by providing for the acceleration of vesting upon termination of their employment in certain circumstances in connection with a change in control of the Company. The awards are not considered probable of vesting and the Company will continue to evaluate the probability going forward. These modifications impacted the stock awards of 12 executive employees and resulted in no incremental compensation cost for the fiscal year ended January 29, 2017 since it is not considered probable as of this date that a change of control will occur.

Warrant. On October 5, 2016 the Company issued a warrant (the "Warrant") to Comcast Cable Communications Management LLC ("Comcast") to purchase up to 1,086,957 shares (the "Warrant Shares") of the Company’s common stock, par value $0.01 per share, representing a total of $30.0 million of common stock based on the average closing price over the 10 -trading day period ended October 4, 2016, at an exercise price of $0.01 per Warrant Share. The Warrant provides for net share settlement that, if elected by Comcast, will reduce the number of Warrant Shares issued upon exercise to reflect net settlement of the exercise price. Comcast may also request cash settlement of the Warrant upon exercise in lieu of the issuance of Warrant Shares; however, such cash settlement is at the sole and absolute discretion of the Company. The Warrant vested 10% on its issuance, and the remainder vests based on the achievement during the subsequent 30 -month period ("Milestone Period") by Comcast (or its designee) of certain milestones related to the deployment of a LoRaWAN™-based network in cities around the country. The number of Warrant Shares are subject to customary adjustment provisions for stock split, reclassification, reorganization, consolidation, merger, and similar transactions. The Warrant has a term of seven years from October 5, 2016.

The Warrant was issued by the Company to Comcast in connection with an agreement between the parties regarding the intended trial deployment by Comcast of a low-power wide-area Network ("LPWAN") in the United States, based on the Company’s LoRa wireless Radio Frequency ("RF") technology.

The Warrant is accounted for as equity. The cost of the Warrant is recognized as an offset to net sales over the respective performance period which is expected to be completed by April 2018. The Warrant consists of five performance tranches. The cost associated with each tranche is recognized based on the fair value at each reporting date until vesting which is the measurement date.

The following table summarizes the underlying Warrant Shares issued to Comcast for fiscal years 2017 and 2016 .



(in thousands, except for per Warrant Share amounts)	Number of Warrant Shares		Weighted Average Grant Date Fair Value (per Warrant Share)
Balance at January 31, 2016	—		$	—
Warrant shares granted	1,087		27.74
Warrant shares vested	(109	)	27.74
Balance at January 29, 2017	978		$	27.74

Given the nominal exercise price of the Warrant Share, the Company valued the awards using the closing price of the Company’s stock on the measurement date for shares that have vested and the fair value on the consolidated balance sheets date for the other shares. As of January 29, 2017 , no part of the Warrant has been exercised, and the Warrant has a contractual life of seven years .

The Company receives an income tax benefit from tax rate differentials due to its presence in foreign jurisdictions such as Switzerland and Canada where statutory rates are lower than U.S. federal tax rates. This income tax benefit is reflected in the line item "Foreign taxes at rates less than federal rates." This line also includes the benefit of the Swiss Ruling discussed below.

The Company, via its Swiss subsidiary, Semtech (International) AG, receives an income tax benefit in Switzerland because only a portion of its total earnings are subject to taxation in Switzerland. Specifically, in the third quarter of fiscal year 2014, the Company received a Swiss tax ruling ("Swiss Ruling"), with an effective date retroactive to the beginning of fiscal year 2014,

101

which allows the Company to compute Swiss income tax using an allocated portion of its total pre-tax earnings that are attributable to the sourcing of production activities. This Swiss Ruling superseded a Swiss tax ruling that was in effect during fiscal years 2012 and 2013.

On December 6, 2016, the Company was granted a tax holiday ("Tax Holiday") with an effective date of January 30, 2017. This Tax Holiday replaces the current Swiss Ruling. The Tax Holiday provides Semtech (International) AG with a 70% reduction to the Cantonal tax rate, bringing the statutory Cantonal tax rate down from 12.56% to 3.77% . The maximum benefit under this Tax Holiday is CHF 500.0 million of cumulative after tax profit which equates to a maximum potential tax savings of CHF 44.0 million . The Tax Holiday is effective for five years and can be extended for an additional five years if the Company meets certain staffing targets by January 30, 2022.

On November 20, 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes, requiring all deferred tax assets and liabilities, and any related valuation allowance, to be classified as non-current on the balance sheet. The classification change for all deferred taxes as non-current simplifies entities’ processes as it eliminates the need to separately identify the net current and net non-current deferred tax asset or liability in each jurisdiction and allocate valuation allowances. The Company elected to prospectively adopt the accounting standard in the beginning of our fourth quarter of fiscal year 2016.

The components of the net deferred income tax assets and liabilities at January 29, 2017 and January 31, 2016 are as follows:



(in thousands)	January 29, 2017			January 31, 2016

As of January 29, 2017 , the Company had federal and state net operating loss carryforwards of $126.7 million and $91.1 million , respectively, which, subject to certain limitations, are available to offset future taxable income through fiscal year 2037. A portion of these losses were generated by Sierra Monolithics Inc. ("SMI") prior to the Company’s purchase of SMI in fiscal year 2010 and therefore are subject to change of control provisions which limit the amount of acquired tax attributes that can be utilized in a given tax year. The Company does not expect these changes in control limitations to significantly impact its ability to utilize these attributes.

Included in the Company’s net operating loss carryforward deferred tax asset is approximately $8.4 million of deferred tax assets attributable to excess equity deductions related to stock awards that are not included on the Company’s consolidated balance sheet. The portion of the Company’s deferred tax asset related to such excess tax benefits is excluded from the Company's recognized deferred tax asset, even if the facts and circumstances indicate that it is more likely than not that the

102

deferred tax asset can be realized. The credit to paid-in-capital will be recorded when the benefit is reflected in the Company's taxes payable.

As of January 29, 2017 , the Company has concluded that its earnings offshore are permanently reinvested and no U.S. tax related to these earnings should be recorded. The Company generally does not provide deferred taxes on its basis difference with respect to its investments in its foreign subsidiaries because the Company believes that they currently have the ability to keep those earnings indefinitely invested and the Company has specific plans for reinvestment of the undistributed foreign earnings.

As of January 29, 2017 , the Company had gross federal and state research credits available of approximately $13.4 million and $14.5 million , respectively, which are available to offset taxable income. These credits will expire between fiscal years 2021 through 2037. As of January 29, 2017 , the Company had federal alternative minimum tax credits available of approximately $1.3 million . The Company also had gross Canadian research credits available of approximately $17.8 million . These credits will expire between fiscal years 2029 and 2037.

As of January 29, 2017 , the Company has a full valuation allowance against its U.S. deferred tax assets of approximately $83.0 million . The Company assessed whether a valuation allowance should be recorded against all of its deferred tax assets ("DTAs") based on the consideration of all available evidence, using a "more likely than not" realization standard. The four sources of taxable income that must be considered in determining whether DTAs will be realized are, (1) future reversals of existing taxable temporary differences (i.e., offset of gross deferred tax assets against gross deferred tax liabilities); (2) taxable income in prior carryback years, if carryback is permitted under the tax law; (3) tax planning strategies and (4) future taxable income exclusive of reversing temporary differences and carryforwards.

In assessing whether a valuation allowance is required, significant weight is given to evidence that can be objectively verified. The Company evaluated its DTAs each reporting period, including an assessment of the cumulative income or loss generated by jurisdiction over the most recent three-year period, to determine if a valuation allowance was required. A significant negative factor in the assessment was the Company’s three-year cumulative loss history as of January 29, 2017 and January 31, 2016 in the U.S.

After a review of the four sources of taxable income described above, the Company determined that the U.S. was in a three-year cumulative loss position as of January 29, 2017 and January 31, 2016 . A three-year cumulative loss is considered to be a significant negative factor and the Company concluded that it is not more likely than not that its DTAs in the U.S. at January 29, 2017 and January 31, 2016 will be realized. As a result, the Company continues to maintain a full valuation allowance on its DTAs in the U.S., with a corresponding charge to the income tax provision of approximately $5.6 million as of January 29, 2017 .

During the fourth quarter of fiscal year 2016, the Company assessed current facts and circumstances and whether a valuation allowance would be appropriate for its Canadian deferred tax assets, and concluded that sufficient positive evidence exists to conclude that it is more likely than not that these deferred tax assets will be realized. The Company is forecasting pretax income growth for its Canadian operations over the next five years, and correspondingly estimated Canadian based taxes over the next five years. The amount of anticipated taxes owed in this period was compared to the Company’s net deferred tax assets to conclude that the Company would be able to utilize its deferred tax assets without any concerns related to expiration. As a result, valuation allowances on the Canadian deferred tax assets were released, with a corresponding benefit to the income tax provision of approximately $7.2 million during fiscal year 2016. Changes in the valuation allowance for the three years ended January 29, 2017 are summarized in the table below:



	Fiscal Year Ended
(in thousands)	January 29, 2017		January 31, 2016			January 25, 2015
Beginning balance	$	77,383	$	75,536		$	61,251
Additions	5,578		9,055			14,285
Releases	—		(7,208		)	—
Ending balance	$	82,961	$	77,383		$	75,536

As of January 29, 2017 , the Company had approximately $603.0 million of unremitted earnings related to the Company’s wholly owned foreign subsidiaries for which income taxes have not been provided.

Uncertain Tax Positions

The Company uses a two-step approach to recognize and measure uncertain tax positions ("UTP"). The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement.

103

A reconciliation of the beginning and ending amount of gross unrecognized tax benefits (before federal impact of state items) is as follows:



	Fiscal Year Ended
(in thousands)	January 29, 2017			January 31, 2016
Beginning balance	$	10,567		$	9,888
Additions based on tax positions related to the current year	1,005			1,454
Reductions for tax positions of prior years, net	(120		)	(775		)
Ending balance	$	11,452		$	10,567

Included in the balance of gross unrecognized tax benefits at January 29, 2017 and January 31, 2016 , are $9.3 million and $8.4 million , respectively, of net tax benefits (after federal impact of state items) that, if recognized, would impact the effective tax rate.

The liability for UTP is reflected on the consolidated balance sheets as follows:



	Fiscal Year Ended
(in thousands)	January 29, 2017		January 31, 2016
Deferred tax assets - non-current	$	9,309	$	9,297
Accrued liabilities	—		—
Other long-term liabilities	2,143		1,270
Total accrued taxes	$	11,452	$	10,567

The Company’s policy is to include net interest and penalties related to unrecognized tax benefits within the provision for taxes on the consolidated statements of income. Since the Company has sufficient net operating losses and research and development ("R&D") credit carryforwards, there would be no cash tax liability, and therefore no additional penalties or interest accrued during fiscal year 2017 . The Company had approximately $0.3 million of net interest and penalties accrued at January 29, 2017 and January 31, 2016 .

Tax years prior to 2012 (the Company’s fiscal year 2013) are generally not subject to examination by the Internal Revenue Service ("IRS") except for items involving tax attributes that have been carried forward to tax years whose statute of limitations remains open. The Company is currently under IRS audit for fiscal years 2012 and 2013 and expects to close those audits within the next twelve months. The Company's positions are expected to be sufficient to address matters that may arise under examination. For state returns, the Company is generally not subject to income tax examinations for years prior to 2011 (the Company’s fiscal year 2012). The Company has a significant tax presence in Switzerland for which Swiss tax filings have been examined through fiscal year 2016. The Company is also subject to routine examinations by various foreign tax jurisdictions in which it operates.

Legal Matters

In accordance with accounting standards regarding loss contingencies, the Company accrues an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated. The Company also discloses the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for its consolidated financial statements not to be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote. The Company evaluates, at least quarterly, developments in its legal matters that could affect the amount of liability that has been previously accrued, and makes adjustments as appropriate. Significant judgment is required to determine both probability and the estimated amount. The Company may be unable to estimate a possible loss or range of possible loss due to various reasons, including, among others: (i) if the damages sought are indeterminate; (ii) if the proceedings are in early stages, (iii) if there is uncertainty as to the outcome of pending appeals, motions or settlements, (iv) if there are significant factual issues to be determined or resolved, and (v) if there are novel or unsettled legal theories presented. In such instances, there is considerable uncertainty regarding the ultimate resolution of such matters, including a possible eventual loss, if any.

Because litigation outcomes are inherently unpredictable, the Company’s evaluation of legal proceedings often involves a series of complex assessments by management about future events and can rely heavily on estimates and assumptions. While the consequences of certain unresolved proceedings are not presently determinable, and an estimate of the probable and reasonably possible loss or range of loss in excess of amounts accrued for such proceedings cannot be reasonably made, an adverse outcome from such proceedings could have a material adverse effect on the Company’s earnings in any given reporting period. However, in the opinion of management, after consulting with legal counsel, any ultimate liability related to current outstanding claims and lawsuits, individually or in the aggregate, is not expected to have a material adverse effect on the Company’s consolidated financial statements, as a whole. However, legal matters are inherently unpredictable and subject to significant uncertainties, some of which are beyond the Company’s control. As such, even though the Company intends to

105

vigorously defend itself with respect to its legal matters, there can be no assurance that the final outcome of these matters will not materially and adversely affect the Company’s business, financial condition, operating results, or cash flows.

From time to time in the ordinary course of its business, the Company is involved in various claims, litigation, and other legal actions that are normal to the nature of its business, including with respect to IP, contract, product liability, employment, and environmental matters. In the opinion of management, after consulting with legal counsel, any ultimate liability related to current outstanding claims and lawsuits, individually or in the aggregate, is not expected to have a material adverse effect on the Company’s consolidated financial statements, as a whole.

The Company’s currently pending legal matters of note are discussed below:

Environmental Matters

In 2001, the Company was notified by the California Department of Toxic Substances Control ("State") that it may have liability associated with the clean-up of the one-third acre Davis Chemical Company site in Los Angeles, California. The Company has been included in the clean-up program because it was one of the companies that used the Davis Chemical Company site for waste recycling and/or disposal between 1949 and 1990. The Company joined with other potentially responsible parties that sent acetone to the site and entered into a Consent Order with the State that required the group to perform a soil investigation at the site and submit a remediation plan. The State has approved the remediation plan, which addressed the group’s initial obligations under the Consent Order. The Consent Order does not require the group to remediate the site and the State has indicated it intends to look to other parties for remediation. To date, the Company’s share of the group’s expenses has not been material and has been expensed as incurred. More recently, the State has decided to pursue a smaller group of parties for additional remediation and/or costs, in particular, parties the State alleges provided chlorinated solvents for recycling, including the Company. Due to the fact that there are fewer parties that are alleged to have provided chlorinated solvent wastes, the potential share of this alleged liability is much larger than the Company’s share of acetone group potential liability. On January 30, 2017, the Company entered into a Consent Decree to settle and resolve all of the State’s claims against the Company, including any liability the Company may have relating to acetone and chlorinated solvents. The Company’s share of the settlement amount to be paid to the State is not material. On January 31, 2017, the State filed its Complaint and lodged the Consent Decree. The Consent Decree needs to be lodged with the Court for at least 30 days. The Consent Decree is also subject to a public comment period of not less than 30 days. The State may modify or withdraw its consent to the Consent Decree if comments received during the public comment period disclose facts or considerations that indicate that the Consent Decree is inappropriate, improper or inadequate. The Company consents to the entry of the Consent Decree without further notice.

The Company has used an environmental firm, specializing in hydrogeology, to perform monitoring of the groundwater at the Company’s former facility in Newbury Park, California that was leased for approximately forty years . The Company vacated the building in May 2002. Certain contaminants have been found in the local groundwater and site soils. The location of key soil contamination (and some related site groundwater impact associated with the soil contamination) is concentrated in and found to emanate from an area of an underground storage tank that the Company believes to have been installed and primarily used in the early 1960s by a former tenant at the site who preceded the Company’s tenancy. There are no litigation claims pending with respect to environmental matters at the Newbury Park site.

The Los Angeles Regional Water Quality Control Board ("RWQCB") having authority over the site issued joint instructions in November 2008, ordering the Company and the current owner of the site to perform additional assessments and surveys, and to create ongoing groundwater monitoring plans before any final regulatory action for "no further action" may be approved. In September 2009, the regulatory agency issued supplemental instructions to the Company and the current site owner regarding previously ordered site assessments, surveys and groundwater monitoring. In October 2013, an order was issued including a scope of proposed additional site work, monitoring, and proposed remediation activities. The Company filed appeals of the October 2013 order seeking reconsideration by the RWQCB and review by the State Water Resources Control Board ("SWRCB") of the removal of two other potentially responsible parties, and seeking clarification of certain other factual findings. In April 2015, the RWQCB denied the Company’s request to name the two other potentially responsible parties to the order, but did correct certain findings of fact identified by the Company in its petition for reconsideration. The SWRCB has not yet ruled on the Company’s petition for review of the RWQCB’s action as the petition was filed with a request it be held in abeyance.

The Company has been engaged with the regulatory agency, including technical discussion between the Company’s environmental firm and RWQCB staff, and has initiated the technical efforts to comply with the order. The Company submitted technical reports prepared by the environmental firm to the RWQCB and has received confirmation regarding the satisfaction of portions of the order. The Company also submitted a remedial action plan prepared by the environmental firm outlining the cleanup of soil, groundwater, and soil vapor at the site. The Company's contractors have installed new monitoring wells and

106

have submitted plans and applications in order to initiate pilot testing of a soil vapor extraction system. The parties are continuing to work toward compliance with the October 2013 order and anticipate working cooperatively on any ultimate proposed cleanup and abatement work.

The Company has accrued liabilities where it is probable that a loss will be incurred and the cost or amount of loss can be reasonably estimated. Based on the latest determinations by the RWQCB and the draft remedial action plan, the Company determined a revised range of probable loss between $5.0 million and $7.2 million . Given the uncertainties associated with environmental assessment and the remediation activities, the Company is unable to determine a best estimate within the range of loss. Therefore, the Company has recorded the minimum amount of probable loss as follows within the Company’s consolidated balance sheets.



(in thousands)	Accrued Liability			Other-Long Term Liability		Total
Balance at January 25, 2015	$	637		$	2,065	$	2,702
Change in estimate	740			2,115		2,855
Utilization	(227		)			(227		)
Balance at January 31, 2016	1,150			4,180		5,330

Utilization	(329		)	—		(329		)
Balance at January 29, 2017	$	620		$	4,381	$	5,001

These estimates could change as a result of changes in planned remedial actions, further actions from the regulatory agency, remediation technology, and other factors.

Indemnification

The Company has entered into agreements with its current and former executives and directors indemnifying them against certain liabilities incurred in connection with the performance of their duties. The Company’s Certificate of Incorporation and Bylaws contain comparable indemnification obligations with respect to the Company’s current directors and employees.

Product Warranties

The Company’s general warranty policy provides for repair or replacement of defective parts. In some cases, a refund of the purchase price is offered. In certain instances the Company has agreed to other or additional warranty terms, including indemnification provisions.

The product warranty accrual reflects the Company’s best estimate of probable liability under its product warranties. The Company accrues for known warranty issues if a loss is probable and can be reasonably estimated, and accrues for estimated incurred but unidentified issues based on historical experience. Historically, warranty expense has been immaterial to the Company’s consolidated financial statements.

Retirement Plans

The Company contributed $1.2 million , $1.3 million and $1.3 million , respe ctively, in fiscal years 2017 , 2016 and 2015 to the 401(k) retirement plan maintained for its employees based in the U.S.

In addition, the Company also contributed $1.0 million , $1.1 million and $1.3 million in fiscal years 2017 , 2016 and 2015 to a defined contribution plan for its employees in Canada.

The Company has a defined benefit pension plan for the employees of its Swiss subsidiary (the "Swiss Plan"). The Swiss Plan is a multiple-employer plan that provides government mandated retirement, death and disability benefits. Under the Swiss Plan, the Company and its employees make government mandated minimum contributions. Minimum contributions are based on the respective employee’s age, salary, and gender. As of January 29, 2017 , the Swiss Plan had an unfunded net pension obligation of approximately $4.7 million , plan assets of approximately $18.2 million , and a projected benefit obligation of approximately $22.8 million . Net periodic pension expense and contributions made by the Company for fiscal year 2017 were $0.7 million , respectively. The entire pension liability has been classified as non-current because the current portion of the liability is not material.

107

Although the Swiss Plan originated in prior years, the Company accounted for the Swiss Plan in accordance with ASC 715-30 Defined Benefit Plans - Pensions starting in 2017. The Company evaluated the impact of not recording the net pension obligation in the Consolidated Balance Sheets and corresponding charges in net income and total comprehensive income in the Consolidated Statements of Income and Comprehensive Income in the historical periods presented, and concluded that the effect was immaterial. The Company corrected the immaterial error in fiscal year 2017 by recording an out of period expense, computed as of February 1, 2016, of $1.4 million reflected in net income, an increase in the pension obligation of $5.8 million , an increase in deferred income tax assets of $1.3 million , and a decrease to accumulated other comprehensive income of $3.1 million .

Deferred Compensation

The Company maintains a deferred compensation plan for certain officers and key executives that allow participants to defer a portion of their compensation for future distribution at various times permitted by the plan. This plan provides for a discretionary Company match up to a defined portion of the employee’s deferral, with any match subject to a vesting period.

Under this plan, the Company incurred an expense, net of forfeitures, of $4.3 million and $2.3 million in the fiscal years ended 2017 and 2015 , respectively, and a benefit, net of forfeitures, of $0.8 million in fiscal year 2016 .

The Company’s liability for the deferred compensation plan is presented below:



(in thousands)	January 29, 2017		January 31, 2016
Accrued liabilities	$	1,732	$	1,448
Other long-term liabilities	22,322		17,976
Total deferred compensation liabilities under this plan	$	24,054	$	19,424

The Company has purchased whole life insurance on the lives of certain current deferred compensation plan participants. This Company-owned life insurance is held in a grantor trust and is intended to cover a majority of the Company’s costs of the deferred compensation plan. The cash surrender value of the Company-owned life insurance was $18.9 million and $16.8 million as of January 29, 2017 and January 31, 2016 , respectively, and is included in "Other assets" on the consolidated balance sheet.

Earn-out Liability

Pursuant to the terms of the amended earn-out arrangement ("Cycleo Amended Earn-Out") with the former shareholders of Cycleo SAS ("Cycleo Earn-Out Beneficiaries"), which the Company acquired on March 7, 2012, the Company potentially may make payments totaling up to approximately $16.0 million based on the achievement of a combination of certain revenue and operating income milestones over a defined period ("Cycleo Defined Earn-Out Period"). The Cycleo Defined Earn-Out Period covers the period April 27, 2015 to April 26, 2020. For certain of the Cycleo Earn-Out Beneficiaries, payment of the earn-out liability is contingent upon continued employment and is accounted for as post-acquisition compensation expense over the service period. The portion of the earn-out liability that is not dependent on continued employment is not considered as compensation expense. The Company has recorded a liability for the Cycleo Amended Earn-Out of $6.1 million and $6.3 million as of January 29, 2017 and January 31, 2016 , respectively, of which $1.4 million is expected to be paid within twelve months. The increase in the liability for the Cycleo Amended Earn-out since January 31, 2016 corresponds to the compensation expense recorded in fiscal year 2016.

Pursuant to the terms of the Triune Earn-out with the former members of Triune ("Triune Earn-out Beneficiaries"), which the Company acquired on March 4, 2015, the Company potentially may make payments totaling up to approximately $70.0 million based on achievement of certain net revenue targets measured at each fiscal year end, starting with fiscal year 2016 and ending in fiscal year 2018. An additional payment of up to $16.0 million may be made based upon a combination of cumulative revenue and contribution margin targets measured from the acquisition date through the end of the Company’s fiscal year 2018. For certain of the Triune Earn-out Beneficiaries, payment of the earn-out liability is contingent upon continued employment and is accounted for as post-acquisition compensation expense over the service period. The portion of the earn-out liability that is not dependent on continued employment is not considered as compensation expense. The Triune Earn-out targets for fiscal years 2017 and 2016 were not met and the Company does not expect the fiscal year 2018 targets to be achieved. Refer to Note 5 for additional discussion regarding fair value measurements.

Note 15 : Concentration of Risk

Significant Customers

Sales to the Company’s customers are generally made on open account, subject to credit limits the Company may impose, and the receivables are subject to the risk of being uncollectible.

The following significant customers accounted for at least 10% of net sales in one or more of the periods indicated:



	Fiscal Year Ended
(percentage of net sales)	January 29, 2017		January 31, 2016		January 25, 2015
Arrow Electronics (and affiliates)	10	%	9	%	9	%
Trend-Tek (and affiliates)	10	%	7	%	5	%
Samsung Electronics (and affiliates)	7	%	7	%	11	%
Premier (and affiliates) ⁽¹⁾	4	%	3	%	3	%


(1)	Premier is a distributor with a concentration of sales to Samsung. The above percentages represent the Company's estimate of the sales activity related to Samsung that is passing through this distributor.

The Company did not have any customer that accounted for at least 10% of total net receivables as of January 29, 2017 or January 31, 2016 .

Outside Subcontractors and Suppliers

The Company relies on a limited number of third-party subcontractors and suppliers for the production of silicon wafers, packaging and certain other tasks. Disruption or termination of supply sources or subcontractors, due to natural disasters such as an earthquake or other causes, could delay shipments and could have a material adverse effect on the Company. Although there are generally alternate sources for these materials and services, qualification of the alternate sources could cause delays sufficient to have a material adverse effect on the Company. Several of the Company’s third-party subcontractors and suppliers, including third-party foundries that supply silicon wafers, are located in foreign countries, including China, Taiwan and Israel. A significant amount of the Company’s assembly and test operations are conducted by third-party contractors in China, Malaysia, Taiwan, Thailand, Korea and the Philippines. For fiscal year 2017 , approximately 25% of the Company’s silicon in terms of cost of wafers was supplied by a third-party foundry in China, and this percentage could be higher in future periods. For fiscal years 2016 and 2015 , approximately 28% and 37% of the Company’s silicon in terms of cost of wafers was supplied by this third-party foundry in China, respectively.

In fiscal year 2017 , authorized distributors accounted for approximately 65% of the Company’s net sales. Generally, the Company does not have long-term contracts with its distributors and most can terminate their agreement with little or no notice. For fiscal year 2017 , our two largest distributors were based in Asia.

Note 16 : Segment Information

Segment Information

See Note 1 regarding recent developments affecting the Company's operating segments.

The Company had five operating segments that existed prior to the third quarter of fiscal year 2017 and currently has four . The Company’s CEO functions as the CODM. The Company’s CODM makes operating decisions and assesses performance based on these operating segments. The four operating segments: Protection Products Group, Power and High-Reliability Products Group, Signal Integrity Products Group, and Wireless and Sensing Products Group, all have similar economic characteristics and have been aggregated into one reportable segment identified in the table below as the "Semiconductor Products Group."

On August 5, 2016, the Company completed its divestiture of its Snowbush IP business, and the Company no longer has a Systems Innovation Group or an "All others" category, which used to be a separate operating segment.

The Company’s assets are commingled among the various operating segments and the CODM does not use that information in making operating decisions or assessing performance. Therefore, the Company has not included asset information by segment below.

Net sales by segment are as follows:

Note 18 : Stock Repurchase Program

The Company maintains a stock repurchase program that was initially approved by its Board of Directors in March 2008. The stock repurchase program does not have an expiration date and the Company’s Board of Directors has authorized expansion of the program over the years. The following table summarizes activity under the program for the fiscal years listed below:



	Fiscal Year Ended
	January 29, 2017			January 31, 2016			January 25, 2015
(in thousands, except number of shares)	Shares	Value		Shares	Value		Shares	Value
Shares repurchased under the 2011 program	39,024	$	1,005	2,681,476	$	57,311	1,578,869	$	40,906
Total treasury shares acquired	39,024	$	1,005	2,681,476	$	57,311	1,578,869	$	40,906

As of January 29, 2017 , the Company had repurchased $136.7 million in shares of its common stock under the program since its inception and the current remaining authorization under the program is $61.7 million . Under the program, the Company may repurchase its common stock at any time or from time to time, without prior notice, subject to market conditions and other considerations. The Company’s repurchases may be made through Rule 10b5-1 and/or Rule 10b-18 or other trading plans, open market purchases, privately negotiated transactions, block purchases or other transactions. The Company intends to fund repurchases under the program from cash on hand. The Company has no obligation to repurchase any shares under the program and may suspend or discontinue it at any time.

Note 19 : Derivatives and Hedging Activities

The Company is exposed to certain risk arising from both its business operations and economic conditions and principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company, on a routine basis and in the normal course of business, experiences expenses denominated in Swiss Franc ("CHF"), Canadian Dollar ("CAD") and Great British Pound ("GBP"). Such expenses expose the Company to exchange rate fluctuations between these foreign currencies and the U.S. Dollar ("USD"). The Company uses derivative financial instruments in the form of forward contracts to mitigate risk associated with adverse movements in these foreign currency exchange rates on a portion of foreign denominated expenses expected to be realized during the current and following fiscal year. Currency forward contracts involve fixing the exchange rate for delivery of a specified amount of foreign currency on a specified date.

The Company’s accounting treatment for these instruments is based on whether or not the instruments are designated as a hedging instrument. The Company is currently applying hedge accounting to all foreign currency derivatives and has designated these hedges as cash flow hedges.

At January 29, 2017 , the Company had the following outstanding foreign exchange contracts:



(in thousands)
Foreign Exchange Contracts	Number of Instruments	Sell Notional Value		Buy Notional Value
Sell USD/Buy GBP Forward Contract	12	$	11,017	£	9,000
Total	12

These contracts, with maturities extending into the subsequent fiscal year, met the criteria for cash flow hedges and the unrealized gains or losses, after tax, are recorded as a component of accumulated other comprehensive gain in shareholders’ equity. The effective portions of cash flow hedges are recorded in accumulated other comprehensive income ("AOCI") until the hedged item is recognized in selling, general and administrative ("SG&A") expense within the consolidated statements of income when the underlying hedged expense is recognized. Any ineffective portions of cash flow hedges are recorded in "Non-operating (expense) income, net" within the Company’s consolidated statements of income. The Company presents its derivative assets and liabilities at their gross fair values on the consolidated balance sheets.

The table below summarizes the carrying values of derivative instruments as of January 29, 2017 . The Company did not have any derivative instruments as of January 31, 2016 .



	Carrying Values of Derivative Instruments as of January 29, 2017
(in thousands)	Fair Value - Assets (2)		Fair Value - (Liabilities) (2)		Derivative Net Carrying Value
Derivatives designated as hedging instruments
Foreign exchange contracts (1)	$	326	$	—	$	326
Total derivatives	$	326	$	—	$	326


(1)	Assets are included in "Other current assets" and liabilities are included in "Accrued liabilities" within the consolidated balance sheets.


(2)	The fair values of the foreign exchange forward contracts are valued using Level 2 inputs. Please refer to Note 5 .

The following table summarizes the amount of income recognized from derivative instruments for the fiscal years ended January 29, 2017 and January 31, 2016 as well as the line items within the accompanying consolidated statements of income where the results are recorded for cash flow hedges:



	Amount of Gain (Loss) Recognized in AOCI on Derivative (Effective Portion)					Location of Gain or Loss into Income (Effective Portion)	Amount of (Gain) Loss Reclassified from AOCI into Income (Effective Portion)					Location of Gain or Loss Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing)	Amount of Gain (Loss) Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing)
	Fiscal Year Ended						Fiscal Year Ended						Fiscal Year Ended

	$	586		$	—		$	(260	)	$	—		$	—		$	—

The amount of gains, net of tax, related to the effective portion of derivative instruments designated as cash flow hedges included in "Accumulated other comprehensive income" within the consolidated balance sheets as of January 29, 2017 and January 31, 2016 was $0.3 million and $0.0 million . Any gains or losses under these contracts are expected to be realized and reclassified to selling, general and administrative within the next twelve months.

Item 9A.	Controls and Procedures

Disclosure Controls and Procedures

The Company carried out an evaluation, under the supervision and with the participation of the CEO and Chief Financial Officer ("CFO"), of the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e)) as of January 29, 2017 . Based on that evaluation, the Company’s CEO and CFO have concluded that such disclosure controls and procedures were effective as of such date.

Changes in Internal Controls

There have been no changes to our internal control over financial reporting that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Management on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Securities Exchange Act of 1934, as amended (the "Exchange Act") Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework set forth in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework, our management has concluded that as of January 29, 2017 the Company’s internal control over financial reporting was effective 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.

Deloitte & Touche LLP, the independent registered public accounting firm that audited the consolidated financial statements included in this report, has issued an attestation report on our internal control over financial reporting as of January 29, 2017 . Deloitte & Touche LLP’s attestation report is included below.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of

Semtech Corporation

Camarillo, California

We have audited the internal control over financial reporting of Semtech Corporation and subsidiaries (the "Company") as of January 29, 2017 , based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable

119

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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of January 29, 2017 , based on the criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule as of and for the year ended January 29, 2017 of the Company and our report dated March 23, 2017 expressed an unqualified opinion on those financial statements and the financial statement schedule.

AMENDED

SEMTECH CORPORATION

EXECUTIVE BONUS PLAN

ARTICLE I

PURPOSE OF THE PLAN

This Plan is established to provide a further incentive to selected executives to promote the success of Semtech Corporation and its Subsidiaries by providing an opportunity to receive additional compensation based on performance as set forth herein, to link those executives’ compensation opportunities to performance, and to facilitate the Company’s ability to attract, retain and motivate top executive talent.

ARTICLE II

DEFINITIONS

ANNUAL SALARY -- The regular annualized rate of base salary of a Participant in effect at the end of the Plan Year to which the applicable incentive award relates, but excluding any incentive compensation, commissions, over-time payments, option exercise income, the value of restricted stock vesting or vesting or payment of restricted stock units, retroactive payments not affecting the base salary or applicable to the current year, and any other payments of compensation of any kind.


2.	APPROVED BUSINESS PLAN -- The Company’s Annual Business Plan as approved by the Board for the applicable Plan Year.


3.	BOARD -- The Board of Directors of the Company.


4.	COMMITTEE -- The Compensation Committee of the Board of Directors as from time to time appointed or constituted by the Board of Directors.


5.	COMPANY -- Semtech Corporation.


6.	EBIT – The Company’s earnings before interest and taxes for the applicable Plan Year on a consolidated basis.

EXECUTIVE -- Any Senior Leadership Team (SLT) member and/or Section 16 Officer, each as determined by the Board or the Committee, who was employed by the Company or one of its Subsidiaries during all or any part of the year; provided, however, that the Company’s Chief Executive Officer shall not be considered an “Executive” for purposes hereof and shall not be eligible to participate in the Plan.


8.	CHIEF EXECUTIVE OFFICER – The Chief Executive Officer of the Company.

NON-GAAP OPERATING INCOME – Operating income of the Company for the applicable Plan Year on a consolidated basis and with such adjustments (i) to take into account or disregard any items or events that the Committee determines in its discretion to be non-recurring or extraordinary or that are not considered reflective of the Company’s core results, and (ii) as the Committee determines to be necessary to best reflect the operating income from ordinary business operations.


10.	PARTICIPANT -- Any Executive selected and approved by the Committee to participate in the Plan in accordance with its terms.


11.	PLAN -- This Semtech Corporation Executive Bonus Plan.


12.	PLAN YEAR -- The Company’s fiscal year.


13.	SECTION 16 OFFICER – An officer who has been determined by the Board to be an officer of the Company subject to the requirements of Section 16 of the Securities Exchange Act of 1934, as amended.


14.	SUBSIDIARY – Any entity in which the Company owns, directly or indirectly, 50% or more of the voting stock or other equity interests.

ARTICLE III

ELIGIBILITY FOR PARTICIPATION

Participants are those Executives selected by the Committee to participate in the Plan. Participation in the Plan shall require Committee approval. No member of the Committee shall be eligible to participate in the Plan.

ARTICLE IV

BONUS POOL

As early as feasible at the beginning of each Plan Year, the Chief Executive Officer shall recommend to the Committee for its review and approval the fiscal year bonus plan. The fiscal year bonus plan shall establish bonus payout factors and bonus pools based on fiscal year achievement of specified level(s) of Non-GAAP Operating Income. The specified level(s) of Non-GAAP Operating Income for a Plan Year may, in the Committee’s discretion, be based on the Approved Business Plan for the applicable Plan Year and/or may take into account or be based on such other factors as the Committee may consider relevant for the particular Plan Year for this purpose. The proposed bonus pool amounts shall be calculated as the sum of (a) the target bonus awards (calculated in accordance with Exhibit A hereto) for Participants for the Plan Year and (b) an estimate of target awards for positions that may be filled during the Plan Year (new hires who may become Participants on a pro rata basis). Fiscal year performance will determine the final fiscal year bonus pool.

2 of 8

Semtech Corporation Executive Bonus Plan

To assist the Committee in making a determination with respect to the Chief Executive Officer’s recommendation, the proposed bonus pool shall also be expressed as a percentage of EBIT. Unless otherwise provided by the Committee, EBIT shall be determined based on the Approved Business Plan for the particular year. At the Committee’s discretion, such EBIT may be computed prior to or after the deduction of incentive compensation payments to be paid under the Plan and may exclude certain extraordinary items.

The Committee shall establish a table for determining the “Organizational Performance Factor” for the Plan Year. The table shall be based on a comparison of Non-GAAP Operating Income for the Plan Year as compared to Non-GAAP Operating Income for the previous Plan Year and shall correlate various percentage improvements in Non-GAAP Operating Income with an Organizational Performance Factor, also expressed as a percentage. The table approved by the Committee for a particular Plan Year is referred to as the “ Performance Goals ” for that Plan Year.

Incentive compensation payments will be made in accordance with Article V. The Committee may impose such limits, if any, as it may determine to be appropriate on the incentive compensation payments (individually or in the aggregate) made under the Plan for any Plan Year notwithstanding anything in Exhibit A to the contrary. The “bonus pool” referenced in this Plan is for budgetary purposes and may be considered by the Committee, but the actual incentive compensation payments determined by the Committee and made under the Plan for any Plan Year may be more than, equal to, or less than the bonus pool for that Plan Year.


5.	The bonus pool does not represent a segregated fund of assets. Participants have no claim on any particular Company asset or group of Company assets, either before or after incentive compensation payments are determined or authorized for the Plan Year. Any incentive compensation awarded under the Plan will be paid from the general assets of the Company.

ARTICLE V

INCENTIVE COMPENSATION PAYMENTS

CALCULATION AND AUTHORIZATION OF PAYMENTS -- Incentive compensation payments to Participants shall be calculated, under the supervision of the Chief Executive Officer, in accordance with the formula and procedures set forth in Exhibit A hereto, and each Participant's incentive award determined under Exhibit A will be recommended to the Committee for its consideration and final approval. No award is payable under the Plan for any Plan Year unless and until the Committee approves that award.

ORGANIZATIONAL PERFORMANCE FACTOR – After the end of the Plan Year, the Non-GAAP Operating Income for the Plan Year, as determined by the Committee, shall be rated against the Non-GAAP Operating Income for the previous Plan Year, as determined by the Committee, to determine the Organization Performance Factor level for all Participants (pursuant to the Performance Goals established for that Plan Year). Pro rata adjustments will be made for whole percentage increments between the levels stated in the table.

3 of 8

Semtech Corporation Executive Bonus Plan


3.	INDIVIDUAL PERFORMANCE FACTORS – A Participant’s Individual Performance Factor shall be based on personal achievement during the Plan Year, as provided in Exhibit A . A Participant’s Individual Performance Factor shall be recommended by the Chief Executive Officer but subject to review, adjustment and final approval by the Committee.


4.	MODIFICATIONS. The Committee may, in its sole discretion, change the method for calculating Plan payments at any time prior to the end of a Plan Year.


5.	METHOD AND TIME OF PAYMENT

The incentive compensation payment authorized for each Participant with respect to each Plan Year shall be paid to such Participant in cash following the close of the Plan Year and within two and one-half months after the close of the Plan Year. The foregoing notwithstanding, the Committee may delay (but not past December 31 of the calendar year in which such Plan Year ends) the payment of awards if it determines in its discretion that circumstances warrant a delay.


B.	All incentive compensation payments shall be made in cash and paid net of any taxes or other amounts required to be withheld.

CLAWBACK POLICY – This Plan, and any awards and payments made under this Plan, are subject to the terms of the Company’s recoupment, clawback or similar policy as it may be in effect from time to time, as well as any similar provisions of applicable law, any of which could in certain circumstances require repayment or forfeiture of awards under and/or any payments received with respect to this Plan.


7.	RIGHTS OF PARTICIPANTS


A.	Selection of an individual as a Participant for one Plan Year does not mean that the individual will be selected to participate in future Plan Years.


B.	The establishment of a bonus pool is subject to the discretion of the Committee. No Participant shall have any right to require the Committee to establish a bonus pool for any Plan Year. No Participant shall have any vested interest or property right or any share in any amounts that may be established as a bonus pool.

All payments are subject to the discretion of the Committee. No Participant shall have any right to require the Committee to authorize any incentive compensation payments under the Plan. Even though the Participant’s performance may be assessed periodically during the Plan Year and/or the progress of Non-GAAP Operating Income may be tracked, all incentive compensation payments are subject to calculation as set forth in Exhibit A and the discretion of the Committee. The mere existence of periodic assessments or tracking does not give the Participant any basis for claiming any incentive compensation under this Plan on a pro rata basis during the Plan Year or otherwise.

4 of 8

Semtech Corporation Executive Bonus Plan

Subject to such exceptions as may be approved by the Committee, a Participant shall have no right to any incentive compensation payment unless he or she is employed by the Company or one of its Subsidiaries on the date such payment is actually made. Nothing in this Plan gives a Participant the right to remain in the employ of the Company or any Subsidiary. Except to the extent explicitly provided otherwise in a then effective written employment contract executed by Participant and the Company (or any Subsidiary that employs the Participant, as the case may be), each Participant is an at will employee whose employment may be terminated by the Participant or by the Company (or Subsidiary that employs the Participant, as the case may be) without liability at any time for any reason.

ARTICLE VI

ADMINISTRATION

The Plan shall be administered by the Committee. The Committee shall have the right to construe the Plan, to interpret any provision of the Plan, to make rules and regulations relating to the Plan, and to determine any factual question arising in connection with the Plan's operation. Any decision made by the Committee under or with respect to the Plan shall be conclusive, final and binding on all parties concerned. The Committee may delegate to the officers or executives of the Company the authority to execute and deliver those instruments and documents, to do all acts and things, and to take all other steps deemed necessary, advisable or convenient for the effective administration of this Plan in accordance with its terms and purpose. For the avoidance of doubt, the Committee may not delegate the duty to approve the bonus pool under Article IV or to authorize awards under Article V. The Plan shall be construed and interpreted to comply with (and avoid any tax, penalty or interest under) Section 409A of the Internal Revenue Code of 1986, as amended.

ARTICLE VII

AMENDMENT OR TERMINATION OF PLAN

The Board or the Committee shall have the unilateral right to terminate or amend this Plan at any time with respect to all or some Participants with respect to any unpaid bonus amounts, and to discontinue the establishment of bonus pools.

ARTICLE VIII

EFFECTIVE DATE

This amended and restated version of the Plan shall be effective beginning with the Company’s 2017 fiscal year.

Approved and Adopted by the Compensation Committee: February 21, 2017

2.	A Participant’s Annual Salary multiplied by the applicable “Target Level” for the Participant (as defined in Section B of this Exhibit A ) establishes the Participant’s “ Target Award ”.


3.	Subject to any discretionary adjustments made pursuant to the Plan and to any limitations contained in the Plan, and unless the Committee provides a different allocation for the particular Plan Year, the actual amount to be awarded to a Participant for any Plan Year pursuant to the terms of this Plan shall be calculated by multiplying the Participant’s Target Award by the sum of


a.	50% of the Organizational Performance Factor determined in accordance with the Performance Goals adopted by the Committee for the applicable Plan Year (with pro rata adjustments being made for whole percentage increments between the levels stated in the table); and


b.	50% of the Individual Performance Factor determined for the Participant for that Plan Year.

However, anything in the Plan to the contrary notwithstanding, in no event shall any amount to be awarded to a Participant for a Plan Year pursuant to the terms of the Plan exceed 200% (or such other percentage as the Committee may establish with respect to the applicable Plan Year) of the Participant’s Target Award for that Plan Year.


4.	Awards generally shall be made only to Participants who are in the employ of the Company or one of its Subsidiaries on the date of payment.

However, awards for Participants who terminate employment after the close of the Plan Year but before awards are paid (and pro-rated awards for Participants who terminate employment during a Plan Year) may be considered by the Committee based on the conditions of the case. A payment, if any, to a former executive (the executive’s estate or designated beneficiary in the case of a deceased Participant) shall be made at the time provided in Section 5 of the Plan.


5.	Pro-rated awards may be approved for individuals who become Participants subsequent to the beginning of a Plan Year.

6 of 8


6.	Recommended awards for Participants whose Target Levels change during the Plan Year will, unless otherwise determined by the Committee, be based on the Target Level in effect when the calculation is made.


7.	The Participant's incentive awards determined under this Exhibit A will be recommended to the Committee for its consideration and approval.

Before the calculated awards are presented to the Committee, the award for any Participant or group of Participants may be adjusted, upward or downward, at the discretion of the Chief Executive Officer. The recommended award for any Participant, or group of Participants, may be adjusted, upward or downward, at the discretion of the Committee. Examples of factors that could lead to an adjustment are subjective criteria such as the Participant’s initiative, leadership, teamwork, judgment, and creativity.


B.	TARGET LEVELS

Target Levels are based on, without limiting any other factors the Committee may consider relevant, the individual’s position and responsibilities in the organization. Target Levels are determined by the Committee. Where a range has been established, the actual Target Level is determined by the Committee will be within the applicable range. The Committee has discretion to modify the range from time to time.



Position	Target Level
Chief Financial Officer	70 - 125%
Chief Operating Officer	70 - 125%
Business Unit and Functional Unit Heads	50 - 125%


C.	INDIVIDUAL PERFORMANCE FACTORS

After the end of each Plan Year, each Participant’s performance will be assessed by the Chief Executive Officer.

Factors relevant in determining a Participant’s Individual Performance Factor may include (1) the Participant’s commitment to, and reinforcement of, the Company’s Core Values and Code of Conduct, (2) , the Participant’s contributions to achieving the Company’s general financial goals and strategic objectives, (3) the Executive’s technical, operational, financial, and managerial achievements in his or her scope of influence, (4) the Executive’s leadership, talent management, customer service, and strategy and execution with respect to new product development or other key projects, and (5) any other factors that the Chief Executive Officer or Committee may consider relevant in the circumstances.

7 of 8

Following the assessment, the Chief Executive Officer will recommend a Individual Performance Rating for each the Executive. The Individual Performance Factor for any Executive, or group of Executives, may be adjusted, upward or downward, at the discretion of the Committee. A Participant’s Individual Performance Factor for a Plan Year shall be subject to a maximum of 200%.

2013 LONG-TERM EQUITY INCENTIVE PLAN
PERFORMANCE UNIT AWARD CERTIFICATE

THIS AWARD is made this [Grant Date] (the “ Award Date ”) by Semtech Corporation, a Delaware corporation (the “ Corporation ”), to [Legal Name] (the “ Participant ”).

R E C I T A L S

A. The Corporation has established the Corporation’s 2013 Long-Term Equity Incentive Plan, as amended from time to time (the “ Plan ”) in order to provide employees and directors of the Corporation with an opportunity to acquire shares of the Corporation’s common stock, par value $0.01 per share (the “ Common Stock ”).

B. The Administrator has determined that it would be in the best interests of the Corporation and its stockholders to grant the performance unit award (the “ Award ”) described in this Award Certificate to the Participant as compensation, as an inducement to remain in the service of the Corporation, and as an incentive for increasing efforts during such service.

NOW, THEREFORE, this Award is made on the following terms and conditions:

1. Definitions and Incorporation . Capitalized terms used in this Award Certificate and not otherwise defined herein shall have the meanings given to such terms in the Plan. The Plan is hereby incorporated in and made a part of this Award Certificate as if fully set forth herein.

2. Award of Performance Units . Pursuant to the Plan, the Corporation hereby awards to the Participant as of the date hereof an Award with respect to [ Amount ] performance units (subject to adjustment in accordance with Section 7.1 of the Plan) (the “ Performance Units ”), which Performance Units are restricted and subject to forfeiture on the terms and conditions hereinafter set forth. As used herein, the term “performance unit” shall mean a non-voting unit of measurement which is deemed solely for purposes of calculating the amount of payment under the Plan and this Award Certificate to be equivalent to one outstanding share of the Corporation’s Common Stock (subject to adjustment in accordance with Section 7.1 of the Plan). The Performance Units shall be used solely as a device for the determination of the payment to eventually be paid to the Participant if such Performance Units vest pursuant to Sections 4, 6 or 7 hereof. The Performance Units shall not be treated as property or as a trust fund of any kind. The Participant acknowledges that the Administrator may use a broker or other third party to facilitate its restricted stock unit award recordkeeping and agrees to comply with any administrative rules and procedures regarding restricted stock unit awards as may be in place from time to time. The Participant acknowledges and agrees that the Corporation may require that any Common Stock received under the Award be deposited in a brokerage account (in the name of the Participant) with a broker designated by the Corporation, and the Participant agrees to take such reasonable steps as the Corporation may require to open and maintain such an account.

3. Rights as a Stockholder; Dividends and Voting .

1 of 11

(a) Limitations on Rights Associated with Units . The Participant shall have no rights as a stockholder of the Corporation, no dividend rights (except as expressly provided in Section 3(b) below with respect to dividend equivalent rights) and no voting rights, with respect to the Performance Units and any shares of Common Stock underlying such Performance Units.

(b) Dividend Equivalent Rights Distributions . In the event that the Corporation pays an ordinary cash dividend on its Common Stock and the related dividend payment record date occurs at any time after the Award Date and before all of the Performance Units subject to the Award have either been paid pursuant to Section 5 or terminated pursuant to Sections 4, 6 or 7, the Corporation shall credit the Participant as of such record date with an additional number of Performance Units equal to (i) the per-share cash dividend paid by the Corporation on its Common Stock with respect to such record date, multiplied by (ii) the total number of outstanding and unpaid Performance Units (including any dividend equivalents previously credited hereunder) (with such total number adjusted pursuant to Section 7.1 of the Plan and/or Section 12 hereof) subject to the Award as of such record date, divided by (iii) the fair market value of a share of Common Stock (as determined under the Plan) on such record date. Any Performance Units credited pursuant to the foregoing provisions of this Section 3(b) shall be subject to the same vesting, payment and other terms, conditions and restrictions as the original Performance Units to which they relate. No crediting of Performance Units shall be made pursuant to this Section 3(b) with respect to any Performance Units which, as of such record date, have either been paid pursuant to Section 5 or terminated pursuant to Sections 4, 6 or 7.

4. Vesting .

(a) Subject to Sections 6 and 7 below, the Award shall vest and become nonforfeitable based on the Corporation’s achievement of the performance goals set forth on Exhibit A attached hereto for each Performance Period (as defined in Exhibit A ). The number of Performance Units that vest and become payable under the Award shall be determined based on the level of results or achievement of the targets set forth on Exhibit A .

(b) Subject to Sections 6 and 7, any Performance Units subject to the Award corresponding to a particular Performance Period that do not vest in accordance with Exhibit A hereto with respect to that Performance Period shall terminate as of the last day of that Performance Period (for clarity, after giving effect to the Administrator’s determination of performance for that Performance Period pursuant to Exhibit A ).

(c) Except as otherwise expressly provided herein, the Participant has no right to pro-rated vesting with respect to the Award if his or her Separation Date (as defined in Section 6) occurs before any applicable vesting date with respect to the Award (regardless of the portion of the vesting period the Participant was actually in the service of the Corporation and/or any of its subsidiaries).

(d) If any unvested Performance Units terminate pursuant to this Agreement, such Performance Units shall automatically terminate and be cancelled as of the applicable termination date without payment of any consideration by the Corporation and without any other action by the Participant, or the Participant’s beneficiary or personal representative, as the case may be.

2 of 11

(e) The provisions of Sections 6 and 7 below supersede any provisions to the contrary in the Corporation’s Executive Change in Control Retention Plan as well as in any written offer letter, employment agreement or other agreement between the Participant and the Corporation. In the event of any inconsistency between this Agreement, on the one hand, and any such offer letter or employment agreement, or the Corporation’s Executive Change in Control Retention Plan, on the other hand, this Agreement shall control.

5. Timing and Manner of Payment of Performance Units . Subject to Section 8 below, upon or as soon as practicable after any Performance Units subject to the Award vest pursuant to Section 4, Section 6, Section 7, and/or Exhibit A , as applicable, and in all events by the 15 ^th day of the third calendar month following the calendar month in which the applicable vesting date occurs, the Corporation shall deliver to the Participant a number of shares of Common Stock (either by delivering one or more certificates for such shares or by entering such shares in book entry form, as determined by the Administrator in its discretion) equal to the number of Performance Units subject to the Award (including any Performance Units issued in respect of dividend equivalent rights) that vested on that vesting date. The Corporation’s obligation to deliver shares of Common Stock or otherwise make payment with respect to vested Performance Units is subject to the condition precedent that the Participant or other person entitled under the Plan to receive any shares or any such payment with respect to the vested Performance Units deliver to the Corporation any representations or other documents or assurances required pursuant to Section 8.1 of the Plan. The Corporation may, in its sole discretion, either ignore fractional share interests or settle them in cash. For clarity, a particular Performance Unit may vest only once.

6. Effect of Termination of Employment or Services . If the Participant ceases to be employed by or ceases to provide services to the Corporation or any of its subsidiaries prior to the last day of a Performance Period, the following rules shall apply as to the Performance Units subject to the Award that correspond to such Performance Period (the last day that the Participant is employed by or provides services to the Corporation or any of its subsidiaries is referred to as the Participant’s “ Separation Date ”).

(a) Other than as expressly provided below in this Section 6, the Participant’s Performance Units shall terminate on the Separation Date. For the avoidance of doubt, if the Separation Date occurs on or following the last day of a Performance Period but before the payment of any Performance Units for such Performance Period, the Participant shall remain eligible to receive payment of any Performance Units that vest for such Performance Period.

(b) If the Participant’s employment by the Corporation or any of its subsidiaries is terminated in such a manner as would entitle the Participant to severance under the Corporation’s Executive Change in Control Retention Plan or a written offer letter or employment agreement between the Participant and the Corporation, and the Participant satisfies any release and other conditions to such severance benefits (such termination, a “ Qualifying Termination ”), the Participant shall remain eligible to vest in the Performance Units subject to the Award in accordance with Exhibit A as though the Separation Date had not occurred. If, after such a Separation Date but prior to the end of the applicable Performance Period, an Acceleration Event (as defined below) should occur, the fixed number of Performance Units determined under Section 7(a) below shall immediately vest and become payable upon the closing of the Acceleration Event without regard to Section 7(b) below.

3 of 11

(c) If the Participant has a Qualifying Termination on or following an Acceleration Event, the remaining then outstanding fixed number of Performance Units determined under Section 7(a) below shall immediately vest and become payable upon the Severance Date.

7. Effect of Certain Corporate Transactions .

(a) In the event of the occurrence, at any time after the Award Date and prior to the end of the Performance Period, of an event described in Section 7.2 of the Plan (which generally covers certain mergers or similar reorganizations) that the Corporation does not survive (or does not survive as a public company in respect of its Common Stock) (an “ Acceleration Event ”), then the number of Performance Units corresponding to each Performance Period under the Award that had not ended prior to the closing date of such Acceleration Event shall become “fixed” and no longer subject to performance measures after such Acceleration Event. For purposes of so fixing the number of Performance Units subject to each such Performance Period, the Performance Period shall be considered to end with the Acceleration Event and such number of Performance Units shall be determined in accordance with Exhibit A based on the Corporation’s performance for the shortened Performance Period(s). No adjustment shall be made pursuant to this Section 7(a) as to any Performance Period that ended prior to the date of the closing of the Acceleration Event. Furthermore, this Section 7 does not apply to any Performance Units that terminate pursuant to Section 6 prior to the date of the closing of the Acceleration Event.

(b) If, in connection with such Acceleration Event, the Administrator has made a provision for the assumption of the Award or the Award would otherwise continue in accordance with its terms in the circumstances, a pro-rata portion of the fixed number of Performance Units determined pursuant to Section 7(a) above with respect to each Performance Period shortened pursuant to Section 7(a) above shall immediately vest and become payable upon the closing of the Acceleration Event, with such pro-rata portion calculated by multiplying such fixed number of Performance Units by a fraction, the numerator of which shall be the number of days that have elapsed from the beginning of the applicable Performance Period through and including the closing date of the Acceleration Event, and the denominator shall be the total number of days in the applicable Performance Period. The Participant shall remain eligible to vest in the remaining (after giving effect to the preceding sentence) portion of the fixed number of Performance Units on the vesting date scheduled to occur at the end of the applicable Performance Period (as the Performance Period was originally scheduled to occur, without giving effect to any shortening of the Performance Period to occur pursuant to Section 7(a)), subject to Section 6.

(c) If the Award is to terminate in connection with such Acceleration Event and the Administrator has not made a provision for the assumption of the Award, the fixed number of Performance Units determined under Section 7(a) above shall immediately vest upon the closing of the Acceleration Event.

(d) For purposes of this Section 7, an award shall be deemed to have been “assumed” if (without limiting other circumstances in which an award is assumed) the award continues after an Acceleration Event, and/or is assumed and continued by the surviving entity following such event (including, without limitation, an entity that, as a result of such event, owns the Corporation or all or substantially all of the Corporation’s assets directly or through one or more subsidiaries (a “Parent”)), and confers the right to purchase or receive, as applicable and subject to

4 of 11

vesting and the other terms and conditions of the award, for each share of Common Stock subject to the award immediately prior to the event, the consideration (whether cash, shares, or other securities or property) received in the event by the stockholders of the Corporation for each share of Common Stock sold or exchanged in such event; provided, however, that if the consideration offered for a share of Common Stock in the event is not solely the ordinary common stock of a successor corporation or a Parent, the Administrator may provide for the consideration to be received upon exercise or payment of the award, for each share subject to the award, to be solely ordinary common stock of the successor corporation or a Parent equal in fair market value to the per share consideration received by the stockholders participating in the event. Any acceleration of vesting upon an Acceleration Event may be deemed to occur immediately prior to such event in order to give effect to such acceleration.

(e) [Notwithstanding Section 7(b), if the Adjustment Event occurs prior to September 1, 2018, the fixed number of Performance Units determined pursuant to Section 7(a) above shall immediately vest upon the closing of the Acceleration Event.] [Bracketed section to be included for Gary Beauchamp only.]

8. Section 409A . Notwithstanding anything to the contrary herein or in the Plan, if the Participant is a “specified employee” within the meaning of Section 409A, and, as a result of that status, any portion of the payments hereunder would otherwise be subject to taxation pursuant to Section 409A of the Code, the Participant shall not be entitled to any payments upon a separation from service until the earlier of (i) the date which is six (6) months after his or her separation from service for any reason other than death, or (ii) the date of the Participant’s death; provided that the first such payment thereafter shall include all amounts that would have been paid earlier but for such six (6) month delay.

9. Non-transferability of Award . This Award is personal and, prior to the time they have become vested pursuant to Sections 4, 6 or 7 hereof, neither the Performance Units nor any rights hereunder may be transferred, assigned, pledged or hypothecated by the Participant in any way (whether by operation of law or otherwise), other than by will or the laws of descent and distribution, nor shall any such rights be subject to execution, attachment or similar process; provided, however, that such restrictions shall not apply to transfers to the Corporation. Except as otherwise provided herein, any attempted alienation, assignment, pledge, hypothecation, attachment, execution or similar process, whether voluntary or involuntary, with respect to all or any part of the Participant’s unvested rights under this Award, shall be null and void.

10. No Right to Continued Employment or Service . Except as provided in Sections 6 and 7, the vesting schedule requires continued employment or service through each applicable vesting date as a condition to the vesting of the applicable installment of the Award and the rights and benefits under the Award. Except as provided in Sections 6 and 7, employment or service for only a portion of the vesting period, even if a substantial portion, will not entitle the Participant to any proportionate vesting or avoid or mitigate a termination of rights and benefits upon or following a termination of services as provided in Section 6 above. Nothing contained in the Plan or the Award constitutes a continued employment or service commitment by the Corporation, confers upon the Participant any right to remain in the employ of or service to the Corporation, interferes with the right of the Corporation at any time to terminate such employment or services, or affects the right of the Corporation to increase or decrease the Participant’s other compensation. By

5 of 11

accepting this Award, the Participant acknowledges and agrees that (a) any person who is terminated before full vesting of an award, such as the one granted to the Participant by this Award Certificate, could attempt to argue that he or she was terminated to preclude vesting; (b) the Participant promises never to make such a claim; and (c) except as otherwise expressly provided herein, in any event, the Participant has no right to pro-rated vesting with respect to the Award if his or her service terminates before any applicable vesting date with respect to the Award (regardless of the portion of the vesting period the Participant was actually in the service of the Corporation and/or any of its subsidiaries).

11. Tax Consequences.

(a) Tax Consultation . The Participant understands that he or she may suffer adverse tax consequences as a result of his or her acceptance of the Award. The Participant represents that he or she has consulted with any tax consultants he or she deems advisable in connection with the acceptance of the Award and that he or she is not relying on the Corporation for any tax advice. By accepting this Award, the Participant acknowledges that he or she shall be solely responsible for the satisfaction of any taxes that may arise (including taxes arising under Section 409A of the Code), and that the Corporation shall not have any obligation whatsoever to pay such taxes.

(b) Withholding . Upon any distribution of shares of Common Stock in respect of the Performance Units, the Corporation shall automatically reduce the number of shares of Common Stock to be delivered by (or otherwise reacquire) the appropriate number of whole shares, valued at their then fair market value (with the “fair market value” of such shares determined in accordance with the applicable provisions of the Plan), to satisfy any withholding obligations of the Corporation or any of its subsidiaries with respect to such distribution of shares at the applicable withholding rates. In the event that the Corporation cannot legally satisfy such withholding obligations by such reduction of shares, or in the event of a cash payment or any other withholding event in respect of the Performance Units, the Corporation (or a subsidiary) shall be entitled to require a cash payment by or on behalf of the Participant and/or to deduct from other compensation payable to the Participant any sums required by federal, state or local tax law to be withheld with respect to such distribution or payment.

12. Adjustments Upon Specified Events . Upon the occurrence of certain events relating to the Corporation’s stock contemplated by Section 7.1 of the Plan, the Administrator shall make adjustments in accordance with such section in the number of Performance Units then outstanding and the number and kind of securities that may be issued in respect of the Award. No such adjustment shall be made with respect to an ordinary cash dividend for which dividend equivalents are credited pursuant to Section 3(b).

13. Severability . In the event that any provision or portion of this Award Certificate shall be determined to be invalid or unenforceable for any reason, in whole or in part, in any jurisdiction, the remaining provisions of this Award Certificate shall be unaffected thereby and shall remain in full force and effect to the fullest extent permitted by law in such jurisdiction, and such invalidity or unenforceability shall have no effect in any other jurisdiction.

14. Binding Effect . This Award Certificate shall extend to, be binding upon and inure to the benefit of the Participant and the Participant’s legal representatives, heirs, successors and

6 of 11

assigns (subject, however, to the limitations set forth in Section 9 with respect to the transfer of this Award Certificate or any rights hereunder or of the Performance Units), and upon the Corporation and its successors and assigns, regardless of any change in the business structure of the Corporation, be it through spinoff, merger, sale of stock, sale of assets or any other transaction.

15. Notices . Any notice to the Corporation contemplated by this Award Certificate shall be addressed to it in care of its President; and any notice to the Participant shall be addressed to him or her at the address on file with the Corporation on the date hereof or at such other address as he or she may hereafter designate in writing.

16. Entire Agreement . This Award Certificate, together with the Plan, constitutes the entire understanding between the Corporation and the Participant with regard to the subject matter of this Award Certificate. They supersede any other agreements, representations or understandings (whether oral or written and whether express or implied) which relate to the subject matter of this Award Certificate.

17. Waiver . The waiver of any breach of any duty, term or condition of this Award Certificate shall not be deemed to constitute a waiver of any preceding or succeeding breach of the same or of any other duty, term or condition of this Award Certificate.

18. Interpretation . The interpretation, construction, performance and enforcement of the terms and conditions of this Award Certificate and the Plan shall lie within the sole discretion of the Administrator, and the Administrator’s determinations shall be conclusive and binding on all interested persons.

19. Choice of Law; Arbitration . This Award Certificate shall be governed by, and construed in accordance with, the laws of the State of Delaware (disregarding any choice-of-law provisions). Any dispute or disagreement regarding the Participant’s rights under this Award Certificate shall be settled solely by binding arbitration in accordance with applicable rules of the American Arbitration Association.

20. Construction . It is intended that the terms of the Award will not result in the imposition of any tax liability pursuant to Section 409A of the Code. This Award Certificate shall be construed and interpreted consistent with that intent.

EXHIBIT A

PERFORMANCE VESTING REQUIREMENTS

Subject to Sections 6 and 7, the Award shall vest and become nonforfeitable as set forth below:

•

One-third of the total number of Performance Units subject to the Award (the “ Fiscal 2018 Target Performance Units ”) shall be eligible to vest and become payable based on the Corporation’s Relative TSR Percentage for the Corporation’s fiscal year 2018 (the “ Fiscal 2018 Performance Period ”), with such number determined by multiplying the Fiscal 2018 Target Performance Units by the applicable percentage determined in accordance with the following table.

•

One-third of the total number of Performance Units subject to the Award (the “ Fiscal 2018-2019 Target Performance Units ”) shall be eligible to vest and become payable based on the Corporation’s Relative TSR Percentage for the two-year performance period consisting of the Corporation’s 2018 and 2019 fiscal years (the “ Fiscal 2018-2019 Performance Period ”), with such number determined by multiplying the Fiscal 2018-2019 Target Performance Units by the applicable percentage determined in accordance with the following table.

•

One-third of the total number of Performance Units subject to the Award (the “ Fiscal 2018-2020 Target Performance Units ”) shall be eligible to vest and become payable based on the Corporation’s Relative TSR Percentage for the three-year performance period consisting of the Corporation’s 2018, 2019 and 2020 fiscal years (the “ Fiscal 2018-2020 Performance Period ”), with such number determined by multiplying the Fiscal 2018-2020 Target Performance Units by the applicable percentage determined in accordance with the following table.



Relative TSR Percentage for the Applicable Performance Period	Applicable Percentage for that Performance Period
Less than -30%	0%
-30%	25%
-20%	50%
0%	100%
25%	150%
50% or greater	200%

For a Relative TSR Percentage between the levels indicated for a particular performance period, the applicable percentage for that Performance Period will be determined pro-rata on a straight-line basis between the two closest points listed in the table above.

9 of 11

Notwithstanding the foregoing, if the Corporation’s TSR for a particular Performance Period is a negative number, the applicable percentage for that Performance Period shall in no case be greater than 100%.

Defined Terms . For purposes of this Exhibit A , the following definitions shall apply:

“ Relative TSR Percentage ” means the Corporation’s TSR for the applicable Performance Period as compared to the TSR achieved by the Index during the applicable Performance Period, expressed as a percentage.

“ Index ” means the SPDR S&P Semiconductor ETF (NYSE: XSD).

“ Performance Period ” means either the Fiscal 2018 Performance Period, the Fiscal 2018-2019 Performance Period, or the Fiscal 2018-2020 Performance Period, as applicable.

“ TSR ” means total stockholder return and shall be determined with respect to the Corporation and the Index for a particular Performance Period by dividing: (a) the applicable Ending Price for such Performance Period by (b) the applicable Beginning Price for such Performance Period. For purposes of determining TSR, the value of dividends and other distributions shall be determined by treating them as reinvested in additional shares at the closing market price on the date of distribution. Any non-cash distributions shall be valued at fair market value.

“ Beginning Price ” means, with respect to the Corporation and the Index for a particular Performance Period, the average of the closing market prices of the Corporation’s Common Stock or shares of the Index, as applicable, on the principal exchange on which such shares are traded for the period of thirty (30) consecutive trading days ending with the last trading day immediately prior to the beginning of such Performance Period. As to a share which goes ex-dividend during such thirty (30) day period, the closing market prices as to such share for the portion of such period preceding the ex-dividend date shall be equitably and proportionately adjusted to exclude the amount of the related dividend.

“ Ending Price ” means, with respect to the Corporation and the Index for a particular Performance Period, the average of the closing market prices of the Corporation’s Common Stock or shares of the Index, as applicable, on the principal exchange on which such shares are traded for the period of thirty (30) consecutive trading days ending with the last trading day of such Performance Period. As to a share which goes ex-dividend during such thirty (30) day period, the closing market prices as to such share for the portion of such period preceding the ex-dividend date shall be equitably and proportionately adjusted to exclude the amount of the related dividend.

Effect of an Acceleration Event . Upon an Acceleration Event, the Ending Price for the purpose of determining the Corporation’s TSR shall equal the transaction price per share of the Common Stock paid in connection with such Acceleration Event. The Ending Price for the purpose of determining the Index’s TSR shall be determined as otherwise provided above but measured based on the average of the closing market prices of the Index’s shares on the principal exchange on which such shares are traded for the period of thirty (30) consecutive trading days ending with the last trading day immediately prior to the date of the closing of such Acceleration Event.

10 of 11

Adjustment . With respect to the computation of TSR, Beginning Price, and Ending Price, there shall also be an equitable and proportionate adjustment to the extent (if any) necessary to preserve the intended incentives of the awards and mitigate the impact of any stock split, stock dividend or reverse stock split occurring during the applicable year.

Determination . In the event of any ambiguity or discrepancy, the determination of the Administrator shall be final and binding. Subject to Sections 6 and 7 of the Agreement, any Performance Units corresponding to a particular Performance Period that vest with respect to that Performance Period pursuant to this Exhibit A shall be considered to have vested as of the last day of that Performance Period.
