PART I.
Item 1. Business.
Overview
We design, develop and market analog and mixed-signal integrated circuits (ICs) and other electronic components and circuitry used in high-voltage power conversion. Our products are used in power converters that convert electricity from a high-voltage source (typically 48 volts or higher) to the type of power required for a specified downstream use. In most cases, this conversion entails, among other functions, converting alternating current (AC) to direct current (DC) or vice versa, reducing or increasing the voltage, and regulating the output voltage and/or current according to the customer’s specifications.
A large percentage of our products are ICs used in AC-DC power supplies, which convert the high-voltage AC from a wall outlet to the low-voltage DC required by most electronic devices. Power supplies incorporating our products are used with all manner of electronic products including mobile phones, computers, entertainment and networking equipment, appliances, electronic utility meters, industrial controls and LED lights.
Since our May 2012 acquisition of CT-Concept Technologie AG (Concept), we also offer insulated-gate bipolar transistor (IGBT) drivers - circuit boards containing multiple ICs, electrical isolation components and other circuitry - used to operate arrays of high-voltage, high-power transistors known as IGBT modules. These driver/module combinations are used for power conversion in high-power applications (i.e., power levels ranging from tens of kilowatts up to one gigawatt) such as industrial motors, solar- and wind-power systems, electric vehicles and high-voltage DC transmission systems.
Our products bring a number of important benefits to the power-conversion market compared with less advanced alternatives, including reduced component count and design complexity, smaller size, higher reliability and reduced time-to-market. Our products also improve the energy efficiency of power converters, helping our customers meet the increasingly stringent efficiency standards that have been adopted around the world for many electronic products, and improving the efficacy of renewable-energy systems, electric vehicles and other high-power applications.
While the size of our addressable market fluctuates with changes in macroeconomic conditions, the market has generally exhibited only a modest growth rate over time as growth in the unit volumes of power converters has largely been offset by reductions in the average selling price of components in this market. Therefore, the growth of our business depends primarily on our penetration of the addressable market, and our success in expanding the addressable market by introducing new products that address a wider range of applications. Our growth strategy includes the following elements:
• | Increase the penetration of our ICs in the “low-power” market. The largest proportion of our revenues comes from power-supply applications requiring 500 watts of output or less. We continue to introduce more advanced products that make our IC-based solutions more attractive in this market. We have also increased the size of our sales and field-engineering staff considerably in recent years, and we continue to expand our offerings of technical documentation and design-support tools and services to help customers use our ICs. These tools and services include our PI Expert™ design software, which we offer free of charge, and our transformer-sample service. |
• | Increase the penetration of our products and the size of our market opportunity in “high-power” applications. By virtue of our acquisition of Concept in 2012, we are now able to bring the benefits of integration to higher-power applications (up to one gigawatt). In particular, we sell our IGBT-driver products into applications such as industrial motor drives, renewable energy systems, DC transmission systems and electric vehicles. We seek to further expand the size of our market opportunity in the future by introducing new IGBT-driver products that will enable us to serve a wider range of power levels in the “high-power” market. |
• | Capitalize on the growing demand for more energy-efficient electronic products and lighting technologies, and for cleaner energy and transportation technologies. We believe that energy-efficiency is becoming an increasingly important design criterion for power supplies due largely to the emergence of standards and specifications that encourage, and in some cases mandate, the design of more energy-efficient electronic products. For example, in 2008 the U.S. Department of Energy implemented mandatory federal standards governing the efficiency of external power supplies; these standards have been tightened as of early 2016. Power supplies incorporating our ICs are |
4
generally able to comply with all known efficiency specifications currently in effect, including the new U.S. federal standards mentioned above.
Additionally, technological advances combined with regulatory and legislative actions are resulting in the adoption of alternative lighting technologies such as LEDs. We believe this presents a significant opportunity for us because our ICs are used in driver (i.e., power-supply) circuitry for high-voltage LED lighting applications. Finally, the growing desire for less carbon-intensive sources of energy and modes of transportation represents an opportunity for us since our IGBT drivers are used in renewable-energy systems as well as electric trains and electric vehicles.
Industry Background
Virtually every electronic device that plugs into a wall socket requires a power supply to convert the high-voltage alternating current provided by electric utilities into the low-voltage direct current required by most electronic devices. A power supply may be located inside a device, such as a consumer appliance or desktop computer, or it may be outside the device as in the case of a mobile-phone charger or an adapter for a cordless phone.
Until approximately 1970, AC-DC power supplies were generally in the form of line-frequency, or linear, transformers. These devices, consisting primarily of copper wire wound around an iron core, tend to be bulky and heavy, and typically waste a substantial amount of electricity. In the 1970s, the invention of high-voltage discrete semiconductors enabled the development of a new generation of power supplies known as switched-mode power supplies, or switchers. These switchers generally came to be a cost-effective alternative to linear transformers in applications requiring more than about three watts of power; in recent years the use of linear transformers has declined even further as a result of energy-efficiency standards and higher raw-material prices.
Switchers are generally smaller, lighter-weight and more energy-efficient than linear transformers. However, switchers designed with discrete components are highly complex, containing numerous components and requiring a high level of analog design expertise. Further, the complexity and high component count of discrete switchers make them relatively costly, difficult to manufacture and prone to failures. Also, some discrete switchers lack inherent safety and energy-efficiency features; adding these features may further increase the component count, cost and complexity of the power supply.
In high-power systems such as industrial motor drives, electric locomotives and renewable-energy systems, power conversion is typically performed using arrays of high-power silicon transistors known as IGBT modules; these modules are operated by electronic circuitry known as IGBT drivers, whose function is to ensure accurate, safe and reliable operation of the IGBT modules. Much like discrete power supplies, discrete IGBT drivers tend to be highly complex, requiring a large number of components and a great deal of design expertise.
Our Highly Integrated Approach
In 1994 we introduced TOPSwitch, the industry’s first cost-effective high-voltage IC for switched-mode AC-DC power supplies; we have since introduced a range of other product families such as TinySwitch, LinkSwitch, Hiper and InnoSwitch which have expanded the range of power-supply applications we can address. In May 2012 we acquired Concept, further expanding our addressable market to include IGBT drivers.
Our ICs and IGBT drivers drastically reduce the complexity and component count of power converters compared to typical discrete designs by integrating many of the functions otherwise performed by numerous discrete electronic components, and by eliminating (or reducing the size and cost of) additional components through innovative system design. As a result, our products enable power converters to have superior features and functionality at a total cost equal to or lower than that of many competing alternatives. Our products offer the following key benefits:
• | Fewer Components, Reduced Size and Higher Reliability |
Our highly integrated ICs and IGBT drivers enable designs with up to 70% fewer components than comparable discrete designs. This reduction in component count enhances reliability and efficiency, reduces size, accelerates time-to-market and results in lower manufacturing costs for our customers. Power supplies that incorporate our ICs are also lighter and more portable than comparable power supplies built with copper-and-iron linear transformers, which are still used in some low-power applications.
• | Reduced Time-to-Market, Enhanced Manufacturability |
5
Because our products eliminate much of the complexity associated with the design of power converters, designs can typically be completed in much less time, resulting in more efficient use of our customers' design resources and shorter time-to-market for new designs. The lower component count and reduced complexity enabled by our products also makes designs more suitable for high-volume manufacturing. We also provide extensive hands-on design support as well as online design tools, such as our PI Expert design software, that further reduce time-to-market and product development risks.
• | Energy Efficiency |
Our patented EcoSmart technology, introduced in 1998, improves the energy efficiency of electronic devices during normal operation as well as standby and “no-load” conditions. This technology enables manufacturers to cost-effectively meet the growing demand for energy-efficient products, and to comply with increasingly stringent energy-efficiency requirements. Our Concept IGBT drivers also enable very high efficiency in high-power systems; in many such systems, such as renewable-energy installations, even small efficiency gains can dramatically shorten the payback period over which the cost of a system is recovered through energy savings.
• | Wide Power Range and Scalability |
Products in our current IC families can address AC-DC power supplies with output power up to approximately 500 watts as well as some high-voltage DC-DC applications; our Concept IGBT drivers are used in applications with power levels as high as one gigawatt. Within each of our product families, the designer can scale up or down in power to address a wide range of designs with minimal design effort.
Energy Efficiency
Power supplies often draw significantly more electricity than the amount needed by the devices they power. As a result, billions of dollars' worth of electricity is wasted each year, and millions of tons of greenhouse gases are unnecessarily produced by power plants. Energy waste occurs during the normal operation of a device and in standby mode, when the device is plugged in but idle. For example, computers and printers waste energy while in “sleep” mode. TVs that are turned off by remote control consume energy while awaiting a remote-control signal to turn them back on. A mobile-phone charger left plugged into a wall outlet continues to draw electricity even when not connected to the phone (a condition known as “no-load”). Many common household appliances, such as microwave ovens, dishwashers and washing machines, also consume power when not in use. In fact, a 2015 study by the National Resources Defense Council found that devises that are "always-on" but inactive may be causing as much as $19 billion in annual energy waste in the U.S alone.
Lighting is another major source of energy waste. Less than 5% of the energy consumed by traditional incandescent light bulbs is converted to light, while the remainder is wasted as heat. The Alliance to Save Energy has estimated that a conversion to efficient lighting technologies such as compact fluorescent bulbs and light-emitting diodes, or LEDs, could save as much as $18 billion worth of electricity and 158 million tons of carbon dioxide emissions per year in the United States alone.
In response to concerns about the environmental impact of carbon emissions, policymakers are taking action to promote energy efficiency. For example, the ENERGY STAR® program and the European Union Code of Conduct encourage manufacturers of electronic devices to comply with voluntary energy-efficiency specifications. In 2007 the California Energy Commission (CEC) implemented mandatory efficiency standards for external power supplies. The CEC standards were implemented nationwide in the United States in July 2008 as a result of the Energy Independence and Security Act of 2007, or EISA; these federal standards have been tightened in early 2016. Similar standards for external power supplies took effect in the European Union in 2010 as part of the EU’s EcoDesign Directive for Energy-Related Products.
In 2009 the CEC announced mandatory efficiency standards for televisions, which took effect in 2011, and in January 2012 the CEC announced mandatory efficiency standards for battery-charging systems, which took effect in 2013.
In 2010, the EU EcoDesign Directive implemented standards limiting standby power consumption on a wide range of electronic products; the limit was reduced by 50 percent beginning in 2013, with many products now limited to 500 milliwatts of standby usage. The EISA law also required substantial improvements in the efficiency of lighting technologies beginning in 2012; as of 2014, traditional 100-, 75-, 60- and 40-watt bulbs may no longer be manufactured or sold in the United States. Plans to
6
eliminate conventional incandescent bulbs have also been announced or enacted in other geographies such as Canada, Australia and Europe.
We believe we offer products that enable manufacturers to meet or exceed these regulations, and all other such regulations of which we are aware. Our EcoSmart technology, introduced in 1998, dramatically reduces waste in both operating and standby modes; we estimate that this technology has saved billions of dollars’ worth of standby power worldwide since 1998. In 2010 we introduced our CapZero and SenZero IC families, which eliminate additional sources of standby waste in some power supplies; we have also introduced a range of product families designed specifically for LED-lighting applications.
Products
Below is a brief description of our products:
• | AC-DC power conversion products |
TOPSwitch, our first commercially successful product family, was introduced in 1994. Since that time we have introduced a wide range of products (such as our TinySwitch, LinkSwitch and Hiper families) to increase the level of integration and improve upon the functionality of the original TOPSwitch, and to broaden the range of power levels we can address. In 2010 we introduced our CapZero and SenZero families, which reduce standby-power consumption in certain applications by eliminating waste caused by so-called bleed resistors and sense resistors. Also, by virtue of our 2010 acquisition of Qspeed Semiconductor, we offer a range of high-performance, high-voltage diodes known as Qspeed diodes.
In 2014 we introduced our InnoSwitch product family, which are the first-ever power-supply ICs to combine primary, secondary and feedback circuits into a single package, utilizing a proprietary technology known as FluxLink to enable precise control without the need for optical components, which tend to add cost and diminish the reliability of power supplies.
In January 2015 we further expanded our product portfolio with the acquisition of Cambridge Semiconductor Ltd., a producer of controller ICs for low-power AC-DC applications. Since 2010 we have also introduced products designed specifically for LED-lighting applications, including our LYTSwitch family.
This portfolio of power-conversion products generally addresses power supplies ranging from less than one watt of output up to approximately 500 watts of output, a market we refer to as the “low-power” market. This market consists of an extremely broad range of applications including mobile-device chargers, consumer appliances, utility meters, LCD monitors, main and standby power supplies for desktop computers and TVs, LED lamps, and numerous other consumer and industrial applications.
• | IGBT drivers |
As a result of our May 2012 acquisition of Concept, we offer a range of IGBT-driver products sold primarily under the SCALE and SCALE-2 product-family names. These products are fully assembled circuit boards incorporating multiple ICs, electrical isolation components and other circuitry. We offer both ready-to-operate “plug-and-play” drivers designed specifically for use with particular IGBT modules, as well as “driver cores,” which provide more basic driver functionality that customers can customize to their own specifications after purchase. In addition, we offer custom drivers based on our SCALE technology.
• | High-voltage DC-DC products |
The DPA-Switch family of products, introduced in June 2002, was the first monolithic high-voltage DC-DC power conversion IC designed specifically for use in distributed power architectures. Applications include power-over-Ethernet powered devices such as voice-over-IP phones and security cameras, as well as network hubs, line cards, servers, digital PBX phones, DC-DC converter modules and industrial controls.

Sales, Distribution and Marketing
We sell our products to original equipment manufacturers, or OEMs, and merchant power-supply manufacturers through our direct sales staff and a worldwide network of independent sales representatives and distributors. We have sales offices in the United States, Switzerland, United Kingdom, Germany, Italy, India, China, Japan, South Korea, the Philippines, Singapore and Taiwan. Direct sales to OEMs and merchant power supply manufacturers represented approximately 25% of our net product revenues for each of 2015, 2014 and 2013, while sales to and through distributors accounted for approximately 75% for each of 2015, 2014 and 2013. Most of our distributors are entitled to return privileges based on sales revenue and are protected from price reductions affecting their inventories. Our distributors are not subject to minimum purchase requirements, and sales representatives and distributors can discontinue marketing our products at any time.
Our top ten customers, including distributors that resell to OEMs and merchant power supply manufacturers, accounted for 60% of our net revenues for 2015 and 59% in each of 2014 and 2013.
The following distributors accounted for 10% or more of total net revenues in 2015, 2014 and 2013:

In 2015, 2014 and 2013 sales to customers in the United States accounted for approximately 5% of our net revenues in each of the respective years, and sales to customers outside of the United States accounted for approximately 95% of our net revenues in the same periods. See Note 6, “Significant Customers and International Sales,” in our Notes to Consolidated Financial Statements regarding sales to customers located in foreign countries. See our consolidated financial statements regarding total revenues and profit for the last three fiscal years.
We are subject to risks stemming from the fact that most of our manufacturing and most of our customers are located in foreign jurisdictions. Risks related to our foreign operations are set forth in Item 1A of this Annual Report on Form 10-K, and include: potential weaker intellectual property rights under foreign laws, the burden of complying with foreign laws and foreign-currency exchange risk. See, in particular, the risk factor “Our international sales activities account for a substantial portion of our net revenues, which subjects us to substantial risks” in Item 1A of this Form 10-K.
Backlog
Our sales are primarily made pursuant to standard purchase orders. The quantity of products purchased by our customers as well as shipment schedules are subject to revisions that reflect changes in both the customers' requirements and in manufacturing availability. Historically, our business has been characterized by short-lead-time orders and quick delivery schedules; for this reason, and because orders in backlog are subject to cancellation or postponement, backlog is not necessarily a reliable indicator of future revenues. Furthermore, except in the case of our IGBT-driver products, we do not recognize revenue on distribution sales until our distributors report that they have sold our products to their customers. As a result, our revenues in a given period can differ significantly from the value of the products we ship in the same period. We believe this further reduces the reliability of order backlog as an indicator of future revenues.
Research and Development
Our research and development efforts are focused on improving our technologies, introducing new products to expand our addressable markets, reducing the costs of existing products, and improving the cost-effectiveness and functionality of our customers' power converters. We have assembled teams of highly skilled engineers to meet our research and development goals. These engineers have expertise in high-voltage device structure and process technology, analog IC design, system architecture and packaging.
In 2015, 2014 and 2013, we incurred costs of $57.5 million, $55.0 million and $51.7 million, respectively, for research and development (R&D). R&D expenses increased in 2015 compared to 2014, driven primarily by the addition of employees in connection with our acquisition of Cambridge Semiconductor Limited (CamSemi) (refer to Note 11, Acquisitions, in our Notes to Consolidated Financial Statements, for details); the increase in headcount caused a corresponding increase in salary and other employee-related expenses. R&D expenses increased in 2014 compared to 2013, driven primarily by increased payroll and related expenses as a result of increased headcount, due mainly to the expansion of our product-development efforts.
Intellectual Property and Other Proprietary Rights
We use a combination of patents, trademarks, copyrights, trade secrets and confidentiality procedures to protect our intellectual-property rights. As of December 31, 2015, we held 814 U.S. patents and had received foreign patent protection on these patents resulting in 462 foreign patents. The U.S. patents have expiration dates ranging from 2016 to 2035. We also hold trademarks in the U.S. and various other geographies including Taiwan, Korea, Hong Kong, China, Europe and Japan.
We regard as proprietary some equipment, processes, information and knowledge that we have developed and used in the design and manufacture of our products. Our trade secrets include a high-volume production process that produces our patented high-voltage ICs. We attempt to protect our trade secrets and other proprietary-information through non-disclosure agreements, proprietary information agreements with employees and consultants, and other security measures.
Long-lived Assets
Our long-lived assets consist of property and equipment as well as intangible assets. Our intangible assets consist of developed and in-process technology, licenses, patents, customer relationships, trade name, domain name and goodwill. Our long-lived assets, including property and equipment and intangible assets, are located in the United States and in foreign countries. Approximately 40% of our long lived assets were located in the United States in 2015, 2014 and 2013, while approximately 60%
9
were held outside of the United States. In 2015, 2014 and 2013 a significant amount of our foreign long-lived assets were located in Switzerland, which held approximately 18%, 31% and 33%, respectively, of our total long-lived assets. See Note 2, Summary of Significant Accounting Policies, in our Notes to Consolidated Financial Statements regarding total property and equipment located in foreign countries.
Manufacturing
We contract with three foundries for the manufacture of the vast majority of our silicon wafers: (1) ROHM Lapis Semiconductor Co., Ltd., or Lapis, (formerly OKI Electric Industry), (2) Seiko Epson Corporation, or Epson, (3) X-FAB Semiconductor Foundries AG, or X-FAB. These contractors manufacture wafers using our proprietary high-voltage process technologies at fabrication facilities located in Japan, Germany and the United States.
Our IC products are assembled and packaged by independent subcontractors in China, Malaysia, Thailand and the Philippines. Our ICs are tested predominantly at the facilities of our packaging subcontractors in Asia and, to a small extent, at our headquarters facility in San Jose, California. Our IGBT-driver boards are assembled by an independent subcontractor in Sri Lanka and tested at our facility in Switzerland.
Our fabless manufacturing model enables us to focus on our engineering and design strengths, minimize capital expenditures and still have access to high-volume manufacturing capacity. We utilize both proprietary and standard IC packages for assembly. Some of the materials used in our packages and aspects of assembly are specific to our products. We require our assembly manufacturers to use high-voltage molding compounds which are more difficult to process than industry standard molding compounds. We work closely with our contractors on a continuous basis to maintain and improve our manufacturing processes.
Our proprietary high-voltage processes do not require leading-edge geometries for them to be cost-effective, and can therefore use our foundries’ older, low-cost facilities for wafer manufacturing. However, because of our highly sensitive high-voltage process, we must interact closely with our foundries to achieve satisfactory yields. Our wafer supply agreements with Lapis, Epson and X-FAB expire in April 2018, December 2020 and December 2020, respectively. Under the terms of the Lapis agreement, Lapis has agreed to reserve a specified amount of production capacity and to sell wafers to us at fixed prices, which are subject to periodic review jointly by Lapis and us. In addition, Lapis requires us to supply them with a rolling six-month forecast on a monthly basis. Our agreement with Lapis provides for the purchase of wafers in U.S. dollars, with mutual sharing of the impact of the fluctuations in the exchange rate between the Japanese yen and the U.S. dollar. Under the terms of the Epson agreement, Epson has agreed to reserve a specified amount of production capacity and to sell wafers to us at fixed prices, which are subject to periodic review jointly by Epson and us. The agreement with Epson also requires us to supply rolling six-month forecasts on a monthly basis, to provide for the purchase of wafers in U.S. dollars and to share the impact of the exchange rate fluctuation between the Japanese yen and the U.S. dollar. Under the terms of the X-FAB agreement, X-FAB has agreed to reserve a specified amount of production capacity and to sell wafers to us at fixed prices, which are subject to periodic review jointly by X-FAB and us. The agreement with X-FAB also requires us to supply them with rolling six-month forecasts on a monthly basis. Our purchases of wafers from X-FAB are denominated in U.S. dollars.
Although some aspects of our relationships with Lapis, Epson and X-FAB are contractual, some important aspects of these relationships are not written in binding contracts and depend on the suppliers' continued cooperation. We cannot assure that we will continue to work successfully with Lapis, Epson or X-FAB in the future, that they will continue to provide us with sufficient capacity at their foundries to meet our needs, or that any of them will not seek an early termination of their wafer supply agreement with us. Our operating results could suffer in the event of a supply disruption with one or more of our foundries if we were unable to quickly qualify alternative manufacturing sources for existing or new products or if these sources were unable to produce wafers with acceptable manufacturing yields.
We typically receive shipments from our foundries approximately four to six weeks after placing orders, and lead times for new products can be substantially longer. To provide sufficient time for assembly, testing and finishing, we typically need to receive wafers four weeks before the desired ship date to our customers. As a result of these factors and the fact that customers’ orders can be placed with little advance notice, we have only a limited ability to react to fluctuations in demand for our products. We try to carry a substantial amount of wafer and finished-goods inventory to help offset these risks and to better serve our markets and meet customer demand.

Competition
Competing alternatives to our high-voltage ICs for the power-supply market include monolithic and hybrid ICs from companies such as Fairchild Semiconductor, STMicroelectronics, Infineon, ON Semiconductor and Sanken Electric Company, as well as PWM-controller chips paired with discrete high-voltage bipolar transistors and MOSFETs, which are produced by a large number of vendors, including those listed above as well as such companies as NXP Semiconductors, Diodes Inc., On-Bright Electronics and Dialog Semiconductor. Self-oscillating switchers, built with discrete components supplied by numerous vendors, are also commonly used. For some applications, line-frequency transformers are also a competing alternative to designs utilizing our products. Our IGBT-driver products compete with alternatives from such companies as Avago, Infineon and Semikron, as well as driver circuits made up of discrete devices.
Generally, our products enable customers to design power converters with total bill-of-materials (BOM) costs similar to those of competing alternatives. As a result, the value of our products is influenced by the prices of discrete components, which fluctuate in relation to market demand, raw-material prices and other factors, but have generally decreased over time.
While we vary the pricing of our ICs in response to fluctuations in prices of alternative solutions, we also compete based on a variety of other factors. Most importantly, the highly integrated nature of our products enables designs that utilize fewer total components than comparable discrete designs or designs using other integrated or hybrid products. This enables power converters to be designed more quickly and manufactured more efficiently and reliably than competing designs. We also compete on the basis of product functionality such as safety features and energy-efficiency features and on the basis of the technical support we provide to our customers. This support includes hands-on design assistance as well as a range of design tools and documentation such as software and reference designs. We also believe that our record of product quality and history of delivering products to our customers on a timely basis serve as additional competitive advantages.
Warranty
We generally warrant that our products will substantially conform to the published specifications for 12 months from the date of shipment. Under the terms of our purchase orders, our liability is limited generally to either a credit equal to the purchase price or replacement of the defective part.
Employees
As of December 31, 2015, we employed 595 full-time personnel, consisting of 89 in manufacturing, 203 in research and development, 251 in sales, marketing and applications support, and 52 in finance and administration.

Item 1A. Risk Factors.
In addition to the other information in this report, the following factors should be considered carefully in evaluating our business before purchasing shares of our stock.
Our operating results are volatile and difficult to predict. If we fail to meet the expectations of public market analysts or investors, the market price of our common stock may decrease significantly. Our net revenues and operating results have varied significantly in the past, are difficult to forecast, are subject to numerous factors both within and outside of our control, and may fluctuate significantly in the future. As a result, our operating results could fall below the expectations of public market analysts or investors. If that occurs, the price of our stock may decline.
Some of the factors that could affect our operating results include the following:
• | the demand for our products declining in the major end markets we serve, which may occur due to competitive factors, supply-chain fluctuations or changes in macroeconomic conditions; |
• | our products are sold through distributors, which limits our direct interaction with our end customers, which reduces our ability to forecast sales and increases the complexity of our business; |
• | competitive pressures on selling prices; |
• | the ability of our products to penetrate additional markets; |
• | the volume and timing of orders received from customers; |
• | the inability to adequately protect or enforce our intellectual property rights; |
• | reliance on international sales activities for a substantial portion of our net revenues; |
• | fluctuations in exchange rates, particularly the exchange rate between the U.S. dollar and the Japanese yen, the Euro and the Swiss franc; |
• | expenses we are required to incur (or choose to incur) in connection with our intellectual property litigations; |
13
• | the volume and timing of delivery of orders placed by us with our wafer foundries and assembly subcontractors, and their ability to procure materials; |
• | our ability to develop and bring to market new products and technologies on a timely basis; |
• | earthquakes, terrorists acts or other disasters; |
• | continued impact of changes in securities laws and regulations, including potential risks resulting from our evaluation of our internal controls over financial reporting; |
• | the lengthy timing of our sales cycle; |
• | undetected defects and failures in meeting the exact specifications required by our products; |
• | audits by the Internal Revenue Service, and potential future changes in tax laws may increase the amount of taxes we are required to pay; |
• | our ability to attract and retain qualified personnel; |
• | risks associated with acquisitions and strategic investments; |
• | our ability to successfully integrate, or realize the expected benefits from, our acquisitions; |
• | changes in environmental laws and regulations, including with respect to energy consumption and climate change; |
• | interruptions in our information technology systems; and |
• | uncertainties arising out of economic consequences of current and potential military actions or terrorist activities and associated political instability. |
If demand for our products declines in our major end markets, our net revenues will decrease. A limited number of applications of our products, such as cellphone chargers, LED lights, desktop PCs and consumer appliances make up a significant percentage of our net revenues. We expect that a significant level of our net revenues and operating results will continue to be dependent upon these applications in the near term. The demand for these products has been highly cyclical and has been impacted by economic downturns in the past. Any economic slowdown in the end markets that we serve could cause a slowdown in demand for our ICs. When our customers are not successful in maintaining high levels of demand for their products, their demand for our ICs decreases, which adversely affects our operating results. Any significant downturn in demand in these markets would cause our net revenues to decline and could cause the price of our stock to fall.
Our products are sold through distributors, which limits our direct interaction with our end customers, therefore reducing our ability to forecast sales and increasing the complexity of our business. Sales to distributors accounted for approximately 75% of net revenues in each of the years ended December 31, 2015, 2014 and 2013. Selling through distributors reduces our ability to forecast sales and increases the complexity of our business, requiring us to:
• | manage a more complex supply chain; |
• | monitor the level of inventory of our products at each distributor, and |
• | monitor the financial condition and credit-worthiness of our distributors, many of which are located outside of the United States and not publicly traded. |
Since we have limited ability to forecast inventory levels at our end customers, it is possible that there may be significant build-up of inventories in the distributor channel, with the OEM or the OEM’s contract manufacturer. Such a buildup could result in a slowdown in orders, requests for returns from customers, or requests to move out planned shipments. This could adversely impact our revenues and profits. Any failure to manage these complexities could disrupt or reduce sales of our products and unfavorably impact our financial results.
14
Intense competition in the high-voltage power supply industry may lead to a decrease in our average selling price and reduced sales volume of our products. The high-voltage power supply industry is intensely competitive and characterized by significant price sensitivity. Our products face competition from alternative technologies, such as linear transformers, discrete switcher power supplies, and other integrated and hybrid solutions. If the price of competing solutions decreases significantly, the cost effectiveness of our products will be adversely affected. If power requirements for applications in which our products are currently utilized go outside the cost-effective range of our products, some of these alternative technologies can be used more cost effectively. In addition, as our patents expire, our competitors could legally begin using the technology covered by the expired patents in their products, potentially increasing the performance of their products and/or decreasing the cost of their products, which may enable our competitors to compete more effectively. Our current patents may or may not inhibit our competitors from getting any benefit from an expired patent. Our U.S. patents have expiration dates ranging from 2016 to 2035. We cannot assure that our products will continue to compete favorably or that we will be successful in the face of increasing competition from new products and enhancements introduced by existing competitors or new companies entering this market. We believe our failure to compete successfully in the high-voltage power supply business, including our ability to introduce new products with higher average selling prices, would materially harm our operating results.
If our products do not penetrate additional markets, our business will not grow as we expect. We believe that our future success depends in part upon our ability to penetrate additional markets for our products. We cannot assure that we will be able to overcome the marketing or technological challenges necessary to penetrate additional markets. To the extent that a competitor penetrates additional markets before we do, or takes market share from us in our existing markets, our net revenues and financial condition could be materially adversely affected.
We do not have long-term contracts with any of our customers and if they fail to place, or if they cancel or reschedule orders for our products, our operating results and our business may suffer. Our business is characterized by short-term customer orders and shipment schedules, and the ordering patterns of some of our large customers have been unpredictable in the past and will likely remain unpredictable in the future. Not only does the volume of units ordered by particular customers vary substantially from period to period, but also purchase orders received from particular customers often vary substantially from early oral estimates provided by those customers for planning purposes. In addition, customer orders can be canceled or rescheduled without significant penalty to the customer. In the past, we have experienced customer cancellations of substantial orders for reasons beyond our control, and significant cancellations could occur again at any time. Also, a relatively small number of distributors, OEMs and merchant power supply manufacturers account for a significant portion of our revenues. Specifically, our top ten customers, including distributors, accounted for 60% of our net revenues in the year ended December 31, 2015, and 59% in the year ended December 31, 2014. However, a significant portion of these revenues are attributable to sales of our products through distributors of electronic components. These distributors sell our products to a broad, diverse range of end users, including OEMs and merchant power supply manufacturers, which mitigates the risk of customer concentration to a large degree.
If we are unable to adequately protect or enforce our intellectual property rights, we could lose market share, incur costly litigation expenses, suffer incremental price erosion or lose valuable assets, any of which could harm our operations and negatively impact our profitability. Our success depends upon our ability to continue our technological innovation and protect our intellectual property, including patents, trade secrets, copyrights and know-how. We are currently engaged in litigation to enforce our intellectual property rights, and associated expenses have been, and are expected to remain, material and have adversely affected our operating results. We cannot assure that the steps we have taken to protect our intellectual property will be adequate to prevent misappropriation, or that others will not develop competitive technologies or products. From time to time, we have received, and we may receive in the future, communications alleging possible infringement of patents or other intellectual property rights of others. Costly litigation may be necessary to enforce our intellectual property rights or to defend us against claimed infringement. The failure to obtain necessary licenses and other rights, and/or litigation arising out of infringement claims could cause us to lose market share and harm our business.
As our patents expire, we will lose intellectual property protection previously afforded by those patents. Additionally, the laws of some foreign countries in which our technology is or may in the future be licensed may not protect our intellectual property rights to the same extent as the laws of the United States, thus limiting the protections applicable to our technology.
Our international sales activities account for a substantial portion of our net revenues, which subjects us to substantial risks. Sales to customers outside of the United States of America account for, and have accounted for a large portion of our net revenues, including approximately 95% of our net revenues for the years ended December 31, 2015, and 2014. If our international sales declined and we were unable to increase domestic sales, our revenues would decline and our operating results would be harmed. International sales involve a number of risks to us, including:
15
• | potential insolvency of international distributors and representatives; |
• | reduced protection for intellectual property rights in some countries; |
• | the impact of recessionary environments in economies outside the United States; |
• | tariffs and other trade barriers and restrictions; |
• | the burdens of complying with a variety of foreign and applicable U.S. Federal and state laws; and |
• | foreign-currency exchange risk. |
Our failure to adequately address these risks could reduce our international sales and materially and adversely affect our operating results. Furthermore, because substantially all of our foreign sales are denominated in U.S. dollars, increases in the value of the dollar cause the price of our products in foreign markets to rise, making our products more expensive relative to competing products priced in local currencies.
Fluctuations in exchange rates, particularly the exchange rate between the U.S. dollar and the Japanese yen, Swiss franc and Euro, may impact our gross margin and net income. Our exchange rate risk related to the Japanese yen includes two of our major suppliers, Epson and Lapis, with which we have wafer supply agreements based in U.S. dollars; however, these agreements also allow for mutual sharing of the impact of the exchange rate fluctuation between Japanese yen and the U.S. dollar. Each year, our management and these suppliers review and negotiate pricing; the negotiated pricing is denominated in U.S. dollars but is subject to contractual exchange rate provisions. The fluctuation in the exchange rate is shared equally between Power Integrations and each of these suppliers. We completed the acquisition of Concept (located in Biel, Switzerland) in the second quarter of 2012. We maintain cash denominated in Swiss francs and euros to fund the operations of our Swiss subsidiary. The functional currency of our Swiss subsidiary is the U.S. dollar; gains and losses arising from the re-measurement of non-functional currency balances are recorded in other income in our consolidated statements of income, and material unfavorable exchange-rate fluctuations with the Swiss franc could negatively impact our net income.
If we do not prevail in our litigation, we will have expended significant financial resources, potentially without any benefit, and may also suffer the loss of rights to use some technologies. We are currently involved in a number of patent litigation matters and the outcome of the litigation is uncertain. See Note 10, Legal Proceedings and Contingencies, in our Notes to Consolidated Financial Statements included in this Form 10-K. For example, in one of our patent suits the infringing company has been found to infringe four of our patents. Despite the favorable court finding, the infringing party filed an appeal to the damages awarded. In another matter, we are being sued in an ongoing case for patent infringement. Should we ultimately be determined to be infringing another party’s patents, or if an injunction is issued against us while litigation is pending on those claims, such result could have an adverse impact on our ability to sell products found to be infringing, either directly or indirectly. In the event of an adverse outcome, we may be required to pay substantial damages, stop our manufacture, use, sale, or importation of infringing products, or obtain licenses to the intellectual property we are found to have infringed. We have also incurred, and expect to continue to incur, significant legal costs in conducting these lawsuits, including the appeal of the case we won, and our involvement in this litigation and any future intellectual property litigation could adversely affect sales and divert the efforts and attention of our technical and management personnel, whether or not such litigation is resolved in our favor. Thus, even if we are successful in these lawsuits, the benefits of this success may fail to outweigh the significant legal costs we will have incurred.
We depend on third-party suppliers to provide us with wafers for our products and if they fail to provide us sufficient quantities of wafers, our business may suffer. Our primary supply arrangements for the production of wafers are with Epson, Lapis, and X-FAB. Our contracts with these suppliers expire on varying dates, with the earliest to expire in April 2018. Although some aspects of our relationships with Lapis, X-FAB and Epson are contractual, many important aspects of these relationships depend on their continued cooperation. We cannot assure that we will continue to work successfully with Epson, Lapis and X-FAB in the future, and that the wafer foundries’ capacity will meet our needs. Additionally, one or more of these wafer foundries could seek an early termination of our wafer supply agreements. Any serious disruption in the supply of wafers from Epson, Lapis and X-FAB could harm our business. We estimate that it would take 12 to 24 months from the time we identified an alternate manufacturing source to produce wafers with acceptable manufacturing yields in sufficient quantities to meet our needs.
16
Although we provide our foundries with rolling forecasts of our production requirements, their ability to provide wafers to us is ultimately limited by the available capacity of the wafer foundry. Any reduction in wafer foundry capacity available to us could require us to pay amounts in excess of contracted or anticipated amounts for wafer deliveries or require us to make other concessions to meet our customers’ requirements, or may limit our ability to meet demand for our products. Further, to the extent demand for our products exceeds wafer foundry capacity, this could inhibit us from expanding our business and harm relationships with our customers. Any of these concessions or limitations could harm our business.
If our third-party suppliers and independent subcontractors do not produce our wafers and assemble our finished products at acceptable yields, our net revenues may decline. We depend on independent foundries to produce wafers, and independent subcontractors to assemble and test finished products, at acceptable yields and to deliver them to us in a timely manner. The failure of the foundries to supply us wafers at acceptable yields could prevent us from selling our products to our customers and would likely cause a decline in our net revenues and gross margin. In addition, our IC assembly process requires our manufacturers to use a high-voltage molding compound that has been available from only a few suppliers. These compounds and their specified processing conditions require a more exacting level of process control than normally required for standard IC packages. Unavailability of assembly materials or problems with the assembly process can materially and adversely affect yields, timely delivery and cost to manufacture. We may not be able to maintain acceptable yields in the future.
In addition, if prices for commodities used in our products increase significantly, raw material costs would increase for our suppliers which could result in an increase in the prices our suppliers charge us. To the extent we are not able to pass these costs on to our customers; this would have an adverse effect on our gross margins.
If our efforts to enhance existing products and introduce new products are not successful, we may not be able to generate demand for our products. Our success depends in significant part upon our ability to develop new ICs for high-voltage power conversion for existing and new markets, to introduce these products in a timely manner and to have these products selected for design into products of leading manufacturers. New product introduction schedules are subject to the risks and uncertainties that typically accompany development and delivery of complex technologies to the market place, including product development delays and defects. If we fail to develop and sell new products in a timely manner then our net revenues could decline.
In addition, we cannot be sure that we will be able to adjust to changing market demands as quickly and cost-effectively as necessary to compete successfully. Furthermore, we cannot assure that we will be able to introduce new products in a timely and cost-effective manner or in sufficient quantities to meet customer demand or that these products will achieve market acceptance. Our failure, or our customers’ failure, to develop and introduce new products successfully and in a timely manner would harm our business. In addition, customers may defer or return orders for existing products in response to the introduction of new products. When a potential liability exists we will maintain reserves for customer returns, however we cannot assure that these reserves will be adequate.
In the event of an earthquake, terrorist act or other disaster, our operations may be interrupted and our business would be harmed. Our principal executive offices and operating facilities are situated near San Francisco, California, and most of our major suppliers, which are wafer foundries and assembly houses, are located in areas that have been subject to severe earthquakes, such as Japan. Many of our suppliers are also susceptible to other disasters such as tropical storms, typhoons or tsunamis. In the event of a disaster, such as the earthquake and tsunami in Japan, we or one or more of our major suppliers may be temporarily unable to continue operations and may suffer significant property damage. Any interruption in our ability or that of our major suppliers to continue operations could delay the development and shipment of our products and have a substantial negative impact on our financial results.
Securities laws and regulations, including potential risk resulting from our evaluation of internal controls over financial reporting, will continue to impact our results. Complying with the requirements of the federal securities laws and NASDAQ’s conditions for continued listing have imposed significant legal and financial compliance costs, and are expected to continue to impose significant costs and management burden on us. These rules and regulations also may make it 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. These rules and regulations could also make it more difficult for us to attract and retain qualified executive officers and members of our board of directors, particularly qualified members to serve on our audit committee. Further, the rules and regulations under the Dodd-Frank Wall Street Reform and Consumer Protection Act, which became effective in 2011, may impose significant costs and management burden on us.
17
Additionally, because these laws, regulations and standards are expected to be subject to varying interpretations, their application in practice may evolve over time as new guidance becomes available. This evolution may result in continuing uncertainty regarding compliance matters and additional costs necessitated by ongoing revisions to our disclosure and governance practices.
Because the sales cycle for our products can be lengthy, we may incur substantial expenses before we generate significant revenues, if any. Our products are generally incorporated into a customer’s products at the design stage. However, customer decisions to use our products, commonly referred to as design wins, can often require us to expend significant research and development and sales and marketing resources without any assurance of success. These significant research and development and sales and marketing resources often precede volume sales, if any, by a year or more. The value of any design win will largely depend upon the commercial success of the customer’s product. We cannot assure that we will continue to achieve design wins or that any design win will result in future revenues. If a customer decides at the design stage not to incorporate our products into its product, we may not have another opportunity for a design win with respect to that product for many months or years.
Our products must meet exacting specifications, and undetected defects and failures may occur which may cause customers to return or stop buying our products. Our customers generally establish demanding specifications for quality, performance and reliability, and our products must meet these specifications. ICs as complex as those we sell often encounter development delays and may contain undetected defects or failures when first introduced or after commencement of commercial shipments. We have from time to time in the past experienced product quality, performance or reliability problems. If defects and failures occur in our products, we could experience lost revenue, increased costs, including warranty expense and costs associated with customer support and customer expenses, delays in or cancellations or rescheduling of orders or shipments and product returns or discounts, any of which would harm our operating results.
Audits of our tax returns and potential future changes in tax laws may increase the amount of taxes we are required to pay. Our operations are subject to income and transaction taxes in the United States and in multiple foreign jurisdictions and to review or audit by the U.S. Internal Revenue Service (IRS) and state, local and foreign tax authorities. In addition, the United States, countries in Asia and other countries where we do business have been considering changes in relevant tax, accounting and other laws, regulations and interpretations, including changes to tax laws applicable to multinational companies. These potential changes could adversely affect our effective tax rates or result in other costs to us.
We must attract and retain qualified personnel to be successful and competition for qualified personnel is intense in our market. Our success depends to a significant extent upon the continued service of our executive officers and other key management and technical personnel, and on our ability to continue to attract, retain and motivate qualified personnel, such as experienced analog design engineers and systems applications engineers. The competition for these employees is intense, particularly in Silicon Valley. The loss of the services of one or more of our engineers, executive officers or other key personnel could harm our business. In addition, if one or more of these individuals leaves our employ, and we are unable to quickly and efficiently replace those individuals with qualified personnel who can smoothly transition into their new roles, our business may suffer. We do not have long-term employment contracts with, and we do not have in place key person life insurance policies on, any of our employees.
We are exposed to risks associated with acquisitions and strategic investments. We have made, and in the future intend to make, acquisitions of, and investments in, companies, technologies or products in existing, related or new markets such as Concept. Acquisitions involve numerous risks, including but not limited to:
• | inability to realize anticipated benefits, which may occur due to any of the reasons described below, or for other unanticipated reasons; |

We also in the future may have strategic relationships with other companies, which may decline in value and/or not meet desired objectives. The success of these strategic relationships depends on various factors over which we may have limited or no control and requires ongoing and effective cooperation with strategic partners. Moreover, these relationships are often illiquid, such that it may be difficult or impossible for us to monetize such relationships.
Our inability to successfully integrate, or realize the expected benefits from, our acquisitions could adversely affect our results. We have made, and in the future intend to make, acquisitions of other businesses, such as CamSemi and Concept, and with these acquisitions there is a risk that integration difficulties may cause us not to realize expected benefits. The success of the acquisitions could depend, in part, on our ability to realize the anticipated benefits and cost savings (if any) from combining the businesses of the acquired companies and our business, which may take longer to realize than expected.
Changes in environmental laws and regulations may increase our costs related to obsolete products in our existing inventory. Changing environmental regulations and the timetable to implement them continue to impact our customers’ demand for our products. As a result there could be an increase in our inventory obsolescence costs for products manufactured prior to our customers’ adoption of new regulations. Currently we have limited visibility into our customers’ strategies to implement these changing environmental regulations into their business. The inability to accurately determine our customers’ strategies could increase our inventory costs related to obsolescence.
Interruptions in our information technology systems could adversely affect our business. We rely on the efficient and uninterrupted operation of complex information technology systems and networks to operate our business. Any significant system or network disruption, including but not limited to new system implementations, computer viruses, security breaches, or energy blackouts could have a material adverse impact on our operations, sales and operating results. We have implemented measures to manage our risks related to such disruptions, but such disruptions could still occur and negatively impact our operations and financial results. In addition, we may incur additional costs to remedy any damages caused by these disruptions or security breaches.
Uncertainties arising out of economic consequences of current and potential military actions or terrorist activities and associated political instability could adversely affect our business. Like other U.S. companies, our business and operating results are subject to uncertainties arising out of economic consequences of current and potential military actions or terrorist activities and associated political instability, and the impact of heightened security concerns on domestic and international travel and commerce. These uncertainties could also lead to delays or cancellations of customer orders, a general decrease in corporate spending or our inability to effectively market and sell our products. Any of these results could substantially harm our business and results of operations, causing a decrease in our revenues.
Item 1B. Unresolved Staff Comments.
Not applicable.
Item 2. Properties.
We own our principal executive, administrative, manufacturing and technical offices which are located in San Jose, California. We also own an R&D facility in New Jersey, which was purchased in 2010 in connection with our acquisition of an early-stage R&D company, and a test facility in Biel, Switzerland which was acquired in connection with our acquisition of Concept. We lease administrative office space in Singapore and Switzerland, R&D facilities in Canada and the United Kingdom and a design center in Germany, in addition to sales offices in various countries around the world to accommodate our sales force. We believe that our current facilities are sufficient for our Company; however, if headcount increases above capacity we may need to lease additional space.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion and analysis of our financial condition and results of our operations should be read in conjunction with the consolidated financial statements and the notes to those statements included elsewhere in this Annual Report on Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. See “Cautionary Note Regarding Forward-Looking Statements” at the beginning of this Form 10-K. Our actual results could differ materially from those contained in these forward-looking statements due to a number of factors, including those discussed in Part I, Item 1A “Risk Factors” and elsewhere in this report.
Business Overview
We design, develop and market analog and mixed-signal integrated circuits (ICs) and other electronic components and circuitry used in high-voltage power conversion. Our products are used in power converters that convert electricity from a high-voltage source (typically 48 volts or higher) to the type of power required for a specified downstream use. In most cases, this conversion entails, among other functions, converting alternating current (AC) to direct current (DC) or vice versa, reducing or increasing the voltage, and regulating the output voltage and/or current according to the customer’s specifications.
A large percentage of our products are ICs used in AC-DC power supplies, which convert the high-voltage AC from a wall outlet to the low-voltage DC required by most electronic devices. Power supplies incorporating our products are used with all manner of electronic products including mobile phones, computers, entertainment and networking equipment, appliances, electronic utility meters, industrial controls and LED lights.
Since our May 2012 acquisition of CT-Concept Technologies AG (Concept), we also offer insulated-gate bipolar transistor (IGBT) drivers - circuit boards containing multiple ICs, electrical isolation components and other circuitry - used to operate arrays of high-voltage, high-power transistors known as IGBT modules. These driver/module combinations are used for power conversion in high-power applications (i.e., power levels ranging from tens of kilowatts up to one gigawatt) such as industrial motors, solar- and wind-power systems, electric vehicles and high-voltage DC transmission systems.
Our net revenues were $344.0 million, $348.8 million and $347.1 million in 2015, 2014 and 2013, respectively. In 2015 revenues decreased by $4.8 million due primarily to lower unit sales into the computer end-market, reflecting reduced demand for power supplies for desktop computers, and the industrial end-market, reflecting a broad-based slowdown in demand from the industrial sector of the economy. These reductions were partially offset by higher unit sales into the communications end-market, largely as a result of the success of our InnoSwitch products in mobile-device chargers and by the effect of our acquisition of Cambridge Semiconductor Limited (CamSemi), whose products are used primarily in the communications end-market. In 2014 revenue increased by $1.7 million, due primarily to growth in three of our primary end-market categories (consumer, industrial and computer), driven by higher unit sales for a range of applications including consumer appliances, industrial motor drives and desktop computers. The increase was partially offset by lower sales into the communications end market due primarily to lower unit sales for residential-networking applications and cellphone chargers.
Our top ten customers, including distributors that resell to OEMs and merchant power supply manufacturers, accounted for 60% of our net revenues for 2015 and 59% for each of 2014 and 2013. Our top two customers, both distributors of our products, collectively accounted for approximately 31% of our net revenues for 2015 and 28% in both 2014 and 2013. In each of 2015, 2014 and 2013, international sales made up 95% of net revenues.
Because our industry is intensely price-sensitive, our gross margin (gross profit divided by net revenues) is subject to change based on the relative pricing of solutions that compete with ours. Variations in product mix, end-market mix and customer mix can also cause our gross margin to fluctuate. Also, because we purchase a large percentage of our silicon wafers from foundries located in Japan, our gross margin is influenced by fluctuations in the exchange rate between the U.S. dollar and the Japanese yen. All else being equal, a 10% change in the value of the U.S. dollar compared to the Japanese yen would eventually result in a corresponding change in our gross margin of approximately 0.8% to 1.0%; this sensitivity may increase or decrease depending on the percentage of our wafer supply that we purchase from Japanese suppliers. Also, although our wafer fabrication and assembly operations are outsourced, as are most of our test operations, a portion of our production costs are fixed in nature. As a result, our unit costs and gross profit margin are impacted by the volume of units we produce.
24
Our gross profit, defined as net revenues less cost of revenues, was $173.4 million, or 50% of net revenues, in 2015, compared to $189.6 million, or 54% of net revenues in 2014, and $183.2 million, or 53% of net revenues, in 2013. The decrease in gross margin in 2015 was due primarily to an unfavorable change in end-market mix, with a greater percentage of revenue coming from lower-margin end-markets. In addition, we incurred higher period costs resulting from the amortization of intangibles and inventory write-up related to our acquisition of CamSemi, which took place in the first quarter of 2015 (refer to Note 11, Acquisitions, in our Notes to Consolidated Financial Statements, for details). The increase in 2014 was due primarily to: a favorable end-market mix, with a greater percentage of revenue coming from higher-margin end markets; a decline in the value of the Japanese yen versus the U.S. dollar, which decreased the cost of silicon wafers purchased from our Japanese wafer-fabrication foundries; and unit-cost benefits resulting from higher production volumes.
Total operating expenses in 2015, 2014 and 2013 were $134.4 million, $133.8 million and $129.2 million, respectively. The increase in operating expenses in 2015 was driven primarily by the addition of employees in connection with our acquisition of CamSemi (refer to Note 11, Acquisitions, in our Notes to Consolidated Financial Statements, for details); the increase in headcount caused a corresponding increase in salary and other employee-related expenses. Sales and marketing expenses decreased, due primarily to a decrease in amortization of intangible assets, as our Concept trade name was fully amortized as of the second quarter of 2014, and lower advertising and promotional expenses in 2015. Operating expenses increased in 2014 compared to 2013 as a result of higher R&D expenses, including increased headcount as well as greater engineering-materials and equipment-depreciation expenses, all in support of our product-development efforts. Sales and marketing expenses also increased, due primarily to the expansion of our sales and application-support staffs, which resulted in higher salary and related expenses.
Critical Accounting Policies and Estimates
The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America, or U.S. GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including those listed below. We base our estimates on historical facts and various other assumptions that we believe to be reasonable at the time the estimates are made. Actual results could differ from those estimates.
Our critical accounting policies are as follows:
• | revenue recognition; |
• | stock-based compensation; |
• | estimating write-downs for excess and obsolete inventory; |
• | income taxes; |
• | business combinations; and |
• | goodwill and intangible assets. |
Our critical accounting policies are important to the portrayal of our financial condition and results of operations, and require us to make judgments and estimates about matters that are inherently uncertain. A brief description of these critical accounting policies is set forth below. For more information regarding our accounting policies, see Note 2, Summary of Significant Accounting Policies, in our Notes to Consolidated Financial Statements.
Revenue recognition
Product revenues consist of sales to original equipment manufacturers, or OEMs, merchant power supply manufacturers and distributors. Approximately 75% of our net product sales were made to distributors in 2015. We apply the provisions of Accounting Standards Codification (ASC) 605-10, Revenue Recognition, and all related appropriate guidance. Revenue is recognized when all of the following criteria have been met: (1) persuasive evidence of an arrangement exists, (2) delivery has occurred, (3) the price is fixed or determinable, and (4) collectability is reasonably assured. Customer purchase orders are generally used to determine the existence of an arrangement. Delivery is considered to have occurred when title and risk of loss have transferred to our customer. We evaluate whether the price is fixed or determinable based on the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. With respect to collectability, we perform credit checks for new customers and perform ongoing evaluations of our existing customers’ financial condition and require letters of credit whenever deemed necessary.
25
Sales to international OEMs and merchant power supply manufacturers for shipments from our facility outside of the United States are pursuant to EX Works, or EXW, shipping terms, meaning that title to the product transfers to the customer upon shipment from our foreign warehouse. Sales to international OEM customers and merchant power supply manufacturers that are shipped from our facility in California are pursuant to Delivered at Frontier, or DAF, shipping terms. As such, title to the product passes to the customer when the shipment reaches the destination country and revenue is recognized upon the arrival of the product in that country. Shipments to OEMs and merchant power supply manufacturers in the Americas are pursuant to Free on Board, or FOB, point of origin shipping terms meaning that title is passed to the customer upon shipment. Revenue is recognized upon title transfer for sales to OEMs and merchant power supply manufacturers, assuming all other criteria for revenue recognition are met.
Sales to most distributors are made under terms allowing certain price adjustments and rights of return on our products held by the distributors. As a result of these rights, we defer the recognition of revenue and the costs of revenues derived from sales to these distributors until our distributors report that they have sold our products to their customers. Our recognition of such distributor sell-through is based on point of sales reports received from the distributor, at which time the price is no longer subject to adjustment and is fixed, and the products are no longer subject to return to us except pursuant to warranty terms. The gross profit that is deferred upon shipment to the distributor is reflected as “deferred income on sales to distributors” in the accompanying consolidated balance sheets. The total deferred revenue as of December 31, 2015 and 2014, was approximately $25.7 million and $25.0 million, respectively. The total deferred cost as of December 31, 2015 and 2014, was approximately $10.6 million and $9.8 million, respectively.
Frequently, distributors need to sell at a price lower than the standard distribution price in order to win business. At the time the distributor invoices its customer or soon thereafter, the distributor submits a “ship and debit” price adjustment claim to us to adjust the distributor’s cost from the standard price to the pre-approved lower price. After we verify that the claim was pre-approved, a credit memo is issued to the distributor for the ship and debit claim. We maintain a reserve for these unprocessed claims and for estimated future ship and debit price adjustments. The reserves appear as a reduction to accounts receivable and deferred income on sales to distributors in our accompanying consolidated balance sheets. To the extent future ship and debit claims significantly exceed amounts estimated, there could be a material impact on the deferred revenue and deferred margin ultimately recognized. To evaluate the adequacy of our reserves, we analyze historical ship and debit payments and levels of inventory in the distributor channels.
Sales to certain of our distributors are made under terms that do not include rights of return or price concessions after the product is shipped to the distributor. Accordingly, product revenue is recognized upon shipment and title transfer assuming all other revenue recognition criteria are met.
Stock-based compensation
We apply the provisions of ASC 718-10, Share-Based Payment. Under the provisions of ASC 718-10, we recognize the fair value of stock-based compensation in our financial statements over the requisite service period of the individual grants, which generally equals a four-year vesting period. We use estimates of volatility, expected term, risk-free interest rate, dividend yield and forfeitures in determining the fair value of these awards and the amount of compensation expense to recognize. Changes in the estimated forfeiture rate could result in changes to our current compensation charges for historical grants.
Estimating write-downs for excess and obsolete inventory
When evaluating the adequacy of our valuation adjustments for excess and obsolete inventory, we identify excess and obsolete products and also analyze historical usage, forecasted production based on demand forecasts, current economic trends and historical write-offs. This write-down is reflected as a reduction to inventory in the consolidated balance sheets and an increase in cost of revenues. If actual market conditions are less favorable than our assumptions, we may be required to take additional write-downs, which could adversely impact our cost of revenues and operating results.
Income taxes
Income tax expense is an estimate of current income taxes payable or refundable in the current fiscal year based on reported income before income taxes. Deferred income taxes reflect the effect of temporary differences and carry-forwards that are recognized for financial reporting and income tax purposes.
We account for income taxes under the provisions of ASC 740, Income Taxes. Under the provisions of ASC 740, deferred tax assets and liabilities are recognized based on the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, utilizing the tax rates that are expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We recognize valuation allowances to reduce any
26
deferred tax assets to the amount that we estimate will more likely than not be realized based on available evidence and management’s judgment. We limit the deferred tax assets recognized related to some of our officers’ compensation to amounts that we estimate will be deductible in future periods based upon Internal Revenue Code Section 162(m). In the event that we determine, based on available evidence and management judgment, that all or part of the net deferred tax assets will not be realized in the future, we would record a valuation allowance in the period the determination is made. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with our expectations could have a material impact on our results of operations and financial position.
As of December 31, 2015, we continue to maintain a valuation allowance on our California deferred tax assets as we believe that it is not more likely than not that the deferred tax assets will be fully realized. We also maintain a valuation allowance with respect to some of our deferred tax assets relating primarily to tax credits in Canada and the state of New Jersey as well as Federal capital loss carryforwards.
Business combinations
The purchase price of an acquisition is allocated to the underlying assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. To the extent the purchase price exceeds the fair value of the net identifiable tangible and intangible assets acquired and liabilities assumed, such excess is allocated to goodwill. We determine the estimated fair values after review and consideration of relevant information, including discounted cash flows, quoted market prices and estimates made by management. We adjust the preliminary purchase price allocation, as necessary, during the measurement period of up to one year after the acquisition closing date as we obtain more information as to facts and circumstances existing at the acquisition date impacting asset valuations and liabilities assumed. Acquisition-related costs are recognized separately from the acquisition and are expensed as incurred.
Goodwill and intangible assets
In accordance with ASC 350-10, Goodwill and Other Intangible Assets, we evaluate goodwill for impairment on an annual basis, or as other indicators of impairment emerge. The provisions of ASC 350-10 require that we perform a two-step impairment test. In the first step, we compare the implied fair value of our single reporting unit to its carrying value, including goodwill. If the fair value of our reporting unit exceeds the carrying amount no impairment adjustment is required. If the carrying amount of our reporting unit exceeds the fair value, step two will be completed to measure the amount of goodwill impairment loss, if any exists. If the carrying value of our single reporting unit’s goodwill exceeds its implied fair value, then we record an impairment loss equal to the difference, but not in excess of the carrying amount of the goodwill. Under the amendments of ASC 350-10, Accounting Standards Update (ASU) 2011-08, Testing Goodwill for Impairment, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, we elect this option and after assessing the totality of events or circumstances, we determine it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. We have not elected this option to date. We evaluated goodwill for impairment in the fourth quarters of 2015 and 2014, and concluded that no impairment existed as of December 31, 2015, and December 31, 2014.
ASC 350-10 also requires that intangible assets with estimable useful lives be amortized over their respective estimated useful lives, and reviewed for impairment in accordance with ASC 360-10, Accounting for the Impairment or Disposal of Long-Lived Assets. We review long-lived assets, such as acquired intangibles and property and equipment, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We measure recoverability of assets to be held and used by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, we recognize an impairment charge by the amount by which the carrying amount of the asset exceeds the fair value of the asset.

Comparison of Years Ended December 31, 2015, 2014 and 2013
Net revenues. Net revenues consist of revenues from product sales, which are calculated net of returns and allowances. In 2015 revenues decreased by $4.8 million, due primarily to lower unit sales into the computer end-market, reflecting reduced demand for power supplies for desktop computers, and the industrial end-market, reflecting a broad-based slowdown in demand from the industrial sector of the economy. These reductions were partially offset by higher unit sales into the communications end-market, largely as a result of the success of our InnoSwitch products in mobile-device chargers and by the effect of our acquisition of CamSemi, whose products are used primarily in the communications end-market.
In 2014 revenue increased by $1.7 million, due primarily to growth in three of our primary end-market categories (consumer, industrial and computer), driven by higher unit sales for a range of applications including consumer appliances, industrial motor drives and desktop computers. The increase was partially offset by lower sales into the communications end market due primarily to lower unit sales for residential-networking applications and cellphone chargers.
Our net revenue mix by the end markets served in 2015, 2014 and 2013 were as follows:
Year Ended December 31, | ||||||||
End Market | 2015 | 2014 | 2013 | |||||
Communications | 24 | % | 18 | % | 21 | % | ||
Computer | 7 | % | 10 | % | 10 | % | ||
Consumer | 36 | % | 37 | % | 35 | % | ||
Industrial | 33 | % | 35 | % | 34 | % | ||
Sales to customers outside of the United States were $327.5 million in 2015, compared to $332.8 million in 2014 and $328.5 million in 2013, representing approximately 95% of net revenues in each of 2015, 2014 and 2013. Although power supplies using our products are designed and distributed worldwide, most of these power supplies are manufactured by our customers in Asia. As a result, sales to this region accounted for approximately 80% of our net revenues in each of 2015 and 2014 and 81% in 2013. We expect international sales to continue to account for a large portion of our net revenues for the foreseeable future.
28
Distributors accounted for 75% of our net product sales for each of the years ended December 31, 2015, 2014 and 2013, with direct sales to OEMs and power supply manufacturers accounting for the remainder in each of the corresponding years. In 2015 two distributors accounted for more than 10% of revenues. In each of 2014 and 2013, one distributor accounted for more than 10% of revenues. The following customers each accounted for 10% or more of net revenues during these years:

* Total customer revenue was less than 10% of net revenues.
No other customers accounted for 10% or more of net revenues during these years.
Gross profit. Gross profit is net revenues less cost of revenues. Our cost of revenues consists primarily of the purchase of wafers from our contracted foundries, the assembly, packaging and testing of our products by sub-contractors, product testing performed in our own facility, overhead associated with the management of our supply chain and the amortization of acquired intangible assets. Gross margin is gross profit divided by net revenues. The table below compares gross profit and gross margin for the years ended December 31, 2015, 2014 and 2013:
(dollars in millions) | 2015 | Change | 2014 | Change | 2013 | ||||||||||||
Gross profit | $ | 173.4 | (8.5 | )% | $ | 189.6 | 3.5 | % | $ | 183.2 | |||||||
Gross margin | 50.4 | % | 54.3 | % | 52.8 | % | |||||||||||
The decrease in gross margin from 2014 to 2015 was due primarily to an unfavorable change in end-market mix, with a greater percentage of revenue coming from lower-margin end-markets. In addition, we incurred higher period costs resulting from the amortization of intangibles and inventory write-up related to our acquisition of CamSemi, which took place in the first quarter of 2015 (refer to Note 11, Acquisitions, in our Notes to Consolidated Financial Statements, for details). The increase in gross margin from 2013 to 2014 was due primarily to: a favorable end-market mix, with a greater percentage of revenue coming from higher-margin end markets; a continued decline in the value of the Japanese yen versus the U.S. dollar, which decreased the cost of silicon wafers purchased from our Japanese wafer-fabrication foundries; and unit cost benefits from higher production volumes.
Research and development expenses. R&D expenses consist primarily of employee-related expenses including stock-based compensation and expensed material and facility costs associated with the development of new processes and new products. We also record R&D expenses for prototype wafers related to new products until the products are released to production. The table below compares R&D expenses for the years ended December 31, 2015, 2014 and 2013:
(dollars in millions) | 2015 | Change | 2014 | Change | 2013 | ||||||||||||

Percentage of net revenues | 16.7 | % | 15.8 | % | 14.9 | % | |||||||||||
R&D expenses increased in 2015 as compared to 2014, driven primarily by the addition of employees in connection with our acquisition of CamSemi (refer to Note 11, Acquisitions, in our Notes to Consolidated Financial Statements, for details); the increase in headcount caused a corresponding increase in salary and other employee-related expenses. R&D expenses increased in 2014 compared to 2013, driven primarily by increased payroll and related expenses as a result of increased headcount, due mainly to the expansion of our product-development efforts. We also increased outside-service expenses related to product design and development. These increases were partially offset by lower stock-based compensation expense, reflecting the fact that our 2014 performance-based stock awards failed to vest due to our 2014 performance.
Sales and marketing expenses. Sales and marketing expenses consist primarily of employee-related expenses, including stock-based compensation, commissions to sales representatives, amortization of acquired intangible assets and facilities expenses, including expenses associated with our regional sales and support offices. The table below compares sales and marketing expenses for the years ended December 31, 2015, 2014 and 2013:

Percentage of net revenues | 13.6 | % | 13.7 | % | 13.1 | % | |||||||||||
Sales and marketing expenses decreased in 2015 compared to 2014 due primarily to lower amortization of acquisition-related intangible assets, as our Concept trade name was fully amortized in the second quarter of 2014 and also due to lower advertising and promotional expenses in 2015. Sales and marketing expenses increased in 2014 compared to 2013, due primarily to increased salary and related expenses reflecting the expansion of our sales and application-support staffs. This increase was partially offset by lower amortization of acquisition-related intangible assets, as our Concept trade name was fully amortized in the second quarter of 2014.
General and administrative expenses. General and administrative, or G&A, expenses consist primarily of employee-related expenses, including stock-based compensation expenses for administration, finance, human resources and general management, as well as consulting, professional services, legal and auditing expenses. The table below compares G&A expenses for the years ended December 31, 2015, 2014 and 2013:

Percentage of net revenues | 8.7 | % | 8.9 | % | 9.2 | % | |||||||||||
G&A expenses decreased in 2015 compared to 2014 due primarily to a decrease in legal expenses as a result of lower litigation fees in connection with our Fairchild litigation and decreased outside service fees relating to our CamSemi acquisition completed in January 2015, partially offset by higher patent attorney spending. G&A expenses decreased in 2014 compared to 2013 due primarily to lower stock-based compensation expense, reflecting the fact that our 2014 performance-based stock awards failed to vest due to our 2014 performance. In addition, we incurred lower legal expenses as a result of lower patent fees and general legal fees, partially offset by increased outside service fees related to our acquisition in January 2015 of CamSemi, a UK company (refer to Note 11, Acquisitions, in our Notes to Consolidated Financial Statements for details).
Other income, net. Other income, net consists primarily of interest income earned on cash and cash equivalents, marketable securities and other investments, and the impact of foreign exchange gains or losses. The table below compares other income, net for the years ended December 31, 2015, 2014 and 2013:

Other income decreased in 2015 compared to 2014 due primarily to the unfavorable impact of foreign currency movements relative to the U.S. dollar and the related loss recognized from the re-measurement of monetary foreign currency assets and liabilities of our Swiss subsidiary. Other income decreased in 2014 compared to 2013 due to a 2013 gain realized for the sale of non-operating assets, partially offset by increased interest income in 2014.
Provision for (benefit from)income taxes. Provision for (benefit from) income taxes represents federal, state and foreign taxes. The table below compares the provision for income taxes for the years ended December 31, 2015, 2014 and 2013:

In 2015, our effective tax rate was impacted by the geographic distribution of our world-wide earnings in lower tax jurisdictions and the federal R&D tax credit. In 2014, our effective tax rate was impacted by an agreement reached with the United States Internal Revenue Service to conclude the examination of our income tax returns for the years 2007 through 2009. The resolution of the audit resulted in a federal tax benefit to us of $2.8 million; we also recorded a state tax benefit of $0.5 million. The one-time benefit included the reversal of $4.1 million of related unrecognized tax benefits that had been recorded as non-current liabilities in our consolidated balance sheets. Our effective tax rate for the year ended December 31, 2013, was favorably impacted by the geographic distribution of our world-wide earnings and earnings in lower-tax jurisdictions. Additionally, the rate was favorably impacted by federal research tax credits for 2015, 2014 and 2013.
Liquidity and Capital Resources
We had approximately $173.9 million in cash, cash equivalents and short-term marketable securities at December 31, 2015, compared to $175.3 million at December 31, 2014, and $202.1 million at December 31, 2013. As of December 31, 2015, 2014 and 2013, we had working capital, defined as current assets less current liabilities, of approximately $188.4 million, $210.8 million and $227.0 million, respectively.
On July 5, 2012, we entered into a Credit Agreement (Credit Agreement) with two banks. The Credit Agreement provides us with a $100.0 million revolving line of credit to use for general corporate purposes with a $20.0 million sub-limit for the issuance of standby and trade letters of credit. The Credit Agreement was amended on April 1, 2014, to extend the Credit Agreement termination date from July 5, 2015, to April 1, 2017, with all other terms of the Credit Agreement remaining the same. Our ability to borrow under the revolving line of credit is conditioned upon our compliance with specified covenants, primarily a minimum cash requirement and a debt-to-earnings ratio, with which we are currently in compliance. The Credit Agreement terminates on April 1, 2017, and all advances under the revolving line of credit will become due on such date, or earlier in the event of a default. As of December 31, 2015, we had no amounts outstanding under our agreement.
Our operating activities generated cash of $92.2 million, $85.6 million, and $98.7 million in the years ended December 31, 2015, 2014 and 2013, respectively. In each of these years, cash was primarily generated from operating activities in the ordinary course of business.
In 2015, our net income was $39.1 million, which included non-cash depreciation, amortization and stock-based expenses of $16.5 million, $7.0 million and $14.8 million, respectively. Sources of cash also included: (1) a $13.5 million decrease in inventory due to ongoing reduction efforts; (2) a $4.1 million decrease in accounts receivable due to the timing of collections; and (3) a $3.4 million decrease in prepaid expenses and other assets due to income tax refunds received during the period. These sources of cash were partially offset by a $5.4 million increase in deferred taxes.
In 2014, our net income was $59.5 million, which included non-cash depreciation, amortization and stock-based compensation expenses of $15.9 million, $6.1 million and $14.3 million, respectively. Sources of cash also included: (1) a $8.2 million decrease in prepaid expenses and other assets as a result of lower payments related to legal and R&D services, in addition to tax refunds received during the year; (2) a $2.1 million decrease in accounts receivable as a result of lower sales in the fourth quarter of 2014 compared to 2013 and improved collections; and (3) a $2.3 million increase in accounts payable due to the timing of payments. These sources of cash were partially offset by a $21.7 million increase in our inventories as a result of lower-than expected sales, and by a $3.2 million decrease in taxes payable.
In 2013, our net income was $57.3 million, which included non-cash depreciation, amortization and stock-based compensation expenses of $16.1 million, $7.4 million and $16.5 million, respectively. Sources of cash also included a $4.2 million increase in deferred income on sales to distributors, resulting from increased shipments to distributors in the fourth quarter of 2013 compared to the same period of 2012. These sources of cash were partially offset by a $4.9 million increase in accounts receivable resulting primarily from revenue growth in the fourth quarter of 2013 compared to the same period in 2012.
Our investing activities in the year ended December 31, 2015, resulted in a net $7.7 million use of cash, consisting primarily of $15.5 million in net cash paid for the acquisition of CamSemi, $10.4 million net cash paid for a building purchase (refer to Note 11, Acquisitions, in our Notes to Consolidated Financial Statements, for details) and $11.4 million for purchases of property and equipment, primarily machinery and equipment for use in the manufacture of our products. These uses of cash were partially offset by $29.6 million of proceeds from the sale and maturity of marketable securities, net of purchases.
31
Our investing activities in the year ended December 31, 2014, resulted in a net $38.1 million use of cash, consisting primarily of: (1) $7.2 million, net, for purchases of marketable securities; (2) $23.1 million for purchases of property and equipment, primarily machinery and equipment for production and R&D; (3) $1.3 million for the purchase of power.com, our domain name; and (4) a $6.6 million cash payment to CamSemi under a loan agreement (refer to Note 11, Acquisitions, in our Notes to Consolidated Financial Statements, for further details).
Our investing activities in the year ended December 31, 2013, resulted in a net $90.7 million use of cash, consisting primarily of $78.1 million, net, for purchases of marketable securities and $14.0 million for purchases of property and equipment. Our investment in property and equipment included purchases of manufacturing and R&D equipment, as well as an enterprise resource planning, or ERP, software upgrade and building improvements to our San Jose, California facility.
Our financing activities in the year ended December 31, 2015, resulted in a net use of $55.1 million of cash. Financing activities consisted primarily of $53.7 million for the repurchase of our common stock and $13.9 million for the payment of dividends to stockholders, partially offset by proceeds of $12.6 million from the issuance of common stock, including the exercise of employee stock options and the issuance of shares through our employee stock purchase plan.
Our financing activities in the year ended December 31, 2014, resulted in a net use of $79.6 million of cash, consisting primarily of $80.8 million for the repurchase of our common stock, and $13.2 million for the payment of dividends to stockholders. The use of cash was partially offset by proceeds of $13.9 million from issuance of common stock, including the exercise of employee stock options and the issuance of shares through our employee stock purchase plan.
Our financing activities in the year ended December 31, 2013, resulted in net proceeds of $21.5 million of cash, consisting primarily of $30.2 million from the issuance of common stock, including the exercise of employee stock options and the issuance of shares through our employee stock purchase plan, partially offset by $9.4 million for the payment of dividends to stockholders.
In January 2013, our board of directors declared four quarterly cash dividends in the amount of $0.08 per share paid to stockholders of record at the end of each quarter in 2013. In October 2013, our board of directors declared four quarterly cash dividends in the amount of $0.10 per share to be paid to stockholders of record at the end of each quarter in 2014. In April 2014, our board of directors increased the quarterly dividends for the third and fourth quarters of 2014 to $0.12 per share. In January 2015, our board of directors extended the $0.12 quarterly dividend through each quarter in 2015.
In January 2016, our board of directors declared four quarterly cash dividends in the amount of $0.13 per share to be paid to stockholders of record at the end of each quarter in 2016. The declaration of any future cash dividend is at the discretion of the board of directors and will depend on our financial condition, results of operations, capital requirements, business conditions and other factors, as well as a determination that cash dividends are in the best interest of our stockholders.
In October 2012, our board of directors authorized the use of $50.0 million for the repurchase of our common stock, and in the years ended December 31, 2014, and December 31, 2015, our board of directors authorized the use of an additional $75.0 million and $60.0 million, respectively, for repurchase of our common stock, with repurchases to be executed according to pre-defined price/volume guidelines. In the year ended December 31, 2015, we purchased 1.3 million shares for $53.7 million. In the year ended December 31, 2014, we purchased 1.6 million shares for $80.8 million. No shares were purchased during the year ended December 31, 2013, as the price of our stock exceeded the pre-defined price guidelines throughout the year. As of December 31, 2015, we had $30.0 million available for future stock repurchases. Authorization of future stock repurchase programs is at the discretion of the board of directors and will depend on our financial condition, results of operations, capital requirements, business conditions as well as other factors.
As of December 31, 2015, we had a contractual obligation related to income tax, consisting primarily of unrecognized tax benefits of approximately $13.6 million. The tax obligation was classified as long-term income taxes payable and a portion is recorded in deferred tax assets in our consolidated balance sheet.
In connection with our IRS settlements in 2014 and in 2012, we were entitled to repatriate $106.9 million from our foreign subsidiary without incurring additional U.S. income tax (See Note 8, Provision for Income Taxes, in our Notes to Consolidated Financial Statements).
Our cash, cash equivalents and investment balances may change in future periods due to changes in our planned cash outlays, including changes in incremental costs such as direct and integration costs related to future acquisitions. We expect
32
continued sales growth in our foreign business and plan to use the earnings generated by our foreign subsidiaries to continue to fund both the working capital and growth needs of our foreign entities, along with providing funding for any future foreign acquisitions. We do not provide for U.S. taxes on our undistributed earnings of foreign subsidiaries that we intend to invest indefinitely outside the U.S., unless such taxes are otherwise required under U.S. tax law. Beginning in 2013, we determined that a portion of our foreign subsidiaries current and future earnings may be remitted prospectively to the U.S. for domestic cash flow purposes and, accordingly, provided for the related U.S. taxes in our consolidated financial statements. Currently the majority of our cash and marketable securities are held in the U.S. If we change our intent to invest our undistributed earnings outside the U.S. indefinitely or if a greater amount of undistributed earnings are needed for U.S. operations than previously anticipated and for which U.S. taxes have not been recorded, we would be required to accrue or pay U.S. taxes (subject to an adjustment for foreign tax credits, where applicable) and withholding taxes payable to various foreign countries on some or all of these undistributed earnings. As of December 31, 2015, we had undistributed earnings of foreign subsidiaries that are indefinitely invested outside of the U.S. of approximately $222.0 million.
If our operating results deteriorate in future periods, either as a result of a decrease in customer demand, or severe pricing pressures from our customers or our competitors, or for other reasons, our ability to generate positive cash flow from operations may be jeopardized. In that case, we may be forced to use our cash, cash equivalents and short-term investments, use our current financing or seek additional financing from third parties to fund our operations. We believe that cash generated from operations, together with existing sources of liquidity, will satisfy our projected working capital and other cash requirements for at least the next 12 months.
Off-Balance Sheet Arrangements
As of December 31, 2015 and 2014, we did not have any off-balance sheet arrangements or relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which are typically established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.
Contractual Obligations
As of December 31, 2015, we had the following contractual obligations and commitments, consisting solely of non-cancelable operating lease agreements:

In addition to our contractual obligations noted above we have a contractual obligation related to income tax as of December 31, 2015, which primarily comprises unrecognized tax benefits of approximately $13.6 million, and was classified as long-term income taxes payable and a portion is recorded in deferred tax assets in our consolidated balance sheet.
Item 7A. Quantitative and Qualitative Disclosures About Market Risk.
Interest Rate Risk. Our exposure to market risk for changes in interest rates relates primarily to our investment portfolio. We consider cash invested in highly liquid financial instruments with a remaining maturity of three months or less at the date of purchase to be cash equivalents. Investments in highly liquid financial instruments with maturities greater than three months are classified as short-term investments. We generally hold securities until maturity; however, they may be sold under certain circumstances, including, but not limited to, when necessary for the funding of acquisitions and other strategic investments. As a result of this policy, we classify our investment portfolio as available-for-sale. We invest in high-credit quality issuers and, by policy, limit the amount of credit exposure to any one issuer. As stated in our policy, we seek to ensure the safety and preservation of our invested principal funds by limiting default risk, market risk and reinvestment risk. We mitigate default risk by investing in safe and high-credit quality securities and by constantly positioning our portfolio to respond appropriately to a significant reduction in a credit rating of any investment issuer, guarantor or depository. The portfolio includes only marketable securities with active secondary or resale markets to facilitate portfolio liquidity. At December 31, 2015 and 2014, we held primarily cash equivalents and short-term investments with fixed interest rates. We do not hold any instruments for trading purposes.
33
Our investment securities are subject to market interest rate risk and will vary in value as market interest rates fluctuate. To minimize market risk, we invest in high-credit quality issuers and, by policy, limit the amount of credit exposure to any one issuer, and therefore if market interest rates were to increase or decrease by 10% from interest rates as of December 31, 2015, or December 31, 2014, the increase or decrease in the fair market value of our portfolio on these dates would not have been material. We monitor our investments for impairment on a periodic basis. Refer to Note 2, Summary of Significant Accounting Policies, for a tabular presentation of our available-for-sale investments and the expected maturity dates.
Foreign Currency Exchange Risk. As of December 31, 2015, our primary transactional currency was the U.S. dollar; in addition, we hold cash in Swiss francs and euro as a result of our acquisition of Concept in 2012. Cash balances held in foreign countries are subject to local banking laws and may bear higher or lower risk than cash deposited in the United States. The following represents the potential impact on our pretax income from a change in the value of the U.S. dollar compared to the Swiss franc and euro as of December 31, 2015. This sensitivity analysis applies a change in the U.S. dollar value of 5% and 10%.
December 31, 2015 | |||||||
(in thousands of USD) | 5% | 10% | |||||
Swiss franc and euro foreign exchange impact | $ | 401 | $ | 802 | |||
The foreign exchange rate fluctuation between the U.S. dollar versus the Swiss franc and euro is recorded in other income in our consolidated statements of income.
We have sales offices in various other foreign countries in which our expenses are denominated in the local currency, primary Asia and Western Europe. From time to time we may enter into foreign currency hedging contracts to hedge certain foreign currency transactions. As of December 31, 2015, and December 31, 2014, we did not have an open foreign currency hedge program utilizing foreign currency forward exchange contracts.
With two of our major suppliers, Seiko Epson Corporation, or Epson, and ROHM Lapis Semiconductor Co., Ltd., or Lapis, we have wafer supply agreements based in U.S. dollars; however, our agreements with Epson and Lapis also allow for mutual sharing of the impact of the exchange rate fluctuation between Japanese yen and the U.S. dollar. Each year, our management and these suppliers review and negotiate pricing; the negotiated pricing is denominated in U.S. dollars but is subject to contractual exchange rate provisions. The fluctuation in the exchange rate is shared equally between us and each of these suppliers.
Nevertheless, as a result of our above-mentioned supplier agreements, our gross margin is influenced by fluctuations in the exchange rate between the U.S. dollar and the Japanese yen. All else being equal, a 10% change in the value of the U.S. dollar compared to the Japanese yen would result in a corresponding change in our gross margin of approximately 0.8% to 1.0%; this sensitivity may increase or decrease depending on the percentage of our wafer supply that we purchase from some of our Japanese suppliers and could subject our gross profit and operating results to the potential for material fluctuations.
Item 8. Financial Statements and Supplementary Data.
The financial statements required by this item are set forth in the pages indicated in Item 15(a), and the supplementary data required by this item is included in Note 14, Selected Quarterly Information, in our notes to consolidated financial statements.

Not applicable.
Item 9A. Controls and Procedures.
Evaluation of Disclosure Controls and Procedures
Management is required to evaluate our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act. Disclosure controls and procedures are controls and other procedures designed to provide reasonable assurance that information required to be disclosed in our reports filed under the Exchange Act, such as this Annual Report on Form 10-K, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls and procedures include controls and
34
procedures designed to provide reasonable assurance that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer as appropriate to allow timely decisions regarding required disclosure. Our disclosure controls and procedures include components of our internal control over financial reporting, which consists of control processes designed to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements in accordance with generally accepted accounting principles in the U.S. To the extent that components of our internal control over financial reporting are included within our disclosure controls and procedures, they are included in the scope of our periodic controls evaluation. Based on our management's evaluation (with the participation of our principal executive officer and principal financial officer), our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective as of the end of the period covered by this report.
Management’s Report on Internal Control Over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act. Internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that:
• | pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; |
• | 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 are being made only in accordance with authorizations of our management and directors; and |
• | provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements. |
Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting.
Management conducted an assessment of Power Integrations' internal control over financial reporting as of December 31, 2015, based on the framework established by the Committee of Sponsoring Organization (COSO) of the Treadway Commission in Internal Control - Integrated Framework issued in 2013. Based on this assessment, management concluded that, as of December 31, 2015, our internal control over financial reporting was effective.
The effectiveness of Power Integrations' internal control over financial reporting as of December 31, 2015, has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which appears below.
Changes in Internal Control over Financial Reporting
There were no changes in our internal controls over financial reporting during the fourth quarter of 2015, which were identified in connection with management’s evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of
Power Integrations, Inc.
San Jose, California
We have audited the internal control over financial reporting of Power Integrations, Inc. and subsidiaries (the "Company") as of December 31, 2015, 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 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 December 31, 2015, 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 consolidated financial statement schedule as of and for the year ended December 31, 2015 of the Company and our report dated February 10, 2016 expressed an unqualified opinion on those consolidated financial statements and consolidated financial statement schedule.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of
Power Integrations, Inc.
San Jose, California
We have audited the accompanying consolidated balance sheets of Power Integrations, Inc. and subsidiaries (the “Company”) as of December 31, 2015 and 2014, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2015. Our audits also included the consolidated financial statement schedule listed in the Index at Item 15 (a) 2. These consolidated financial statements and consolidated financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on the consolidated financial statements and consolidated financial statement schedule based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall consolidated financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Power Integrations, Inc. and subsidiaries at December 31, 2015 and 2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such consolidated financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of December 31, 2015 based on the criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 10, 2016 expressed an unqualified opinion on the Company’s internal control over financial reporting.

(“Power Integrations” or the “Company”), incorporated in California on March 25, 1988, and reincorporated in Delaware in December 1997, designs, develops, manufactures and markets analog and mixed-signal integrated circuits (ICs) and other electronic components and circuitry used in high-voltage power conversion. The Company’s products are used in power converters that convert electricity from a high-voltage source (typically 48 volts or higher) to the type of power required for a specified downstream use. A large percentage of the Company’s products are ICs used in AC-DC power supplies in a wide variety of end products, primarily in the consumer, communications, computer and industrial markets. The Company acquired CT-Concept Technologie AG (Concept) in May 2012, and since then offers IGBT drivers used to operate arrays of high-voltage, high-power transistors known as IGBT modules, which are used for power conversion in high-power applications such as industrial motors, solar- and wind-power systems, electric vehicles and high-voltage DC transmission systems.
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
Principles of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries after elimination of all intercompany transactions and balances.
Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition and allowances for receivables and inventories. These estimates are based on historical facts and various other factors, which the Company believes to be reasonable at the time the estimates are made. However, as the effects of future events cannot be determined with precision, actual results could differ significantly from management’s estimates.
Cash and Cash Equivalents
The Company considers cash invested in highly liquid financial instruments with maturities of three months or less at the date of purchase to be cash equivalents.
Marketable Securities
The Company generally holds securities until maturity; however, they may be sold under certain circumstances including, but not limited to, when necessary for the funding of acquisitions and other strategic investments. As a result the Company classifies its investment portfolio as available-for-sale. The Company classifies all investments with a maturity date greater than three months at the date of purchase as short-term marketable securities in its Consolidated Balance Sheet. As of December 31, 2015, and December 31, 2014, the Company’s marketable securities consisted primarily of corporate bonds and other high-quality commercial securities. The weighted average interest rate of investments at December 31, 2015 and December 31, 2014, was approximately 0.84% and 0.76%, respectively.

Building and improvements | 4-40 years |
Machinery and equipment | 2-8 years |
Computer software and hardware and office furniture and fixtures | 4-7 years |
Total property and equipment (excluding accumulated depreciation) located in the United States at December 31, 2015, 2014 and 2013, was approximately $150.1 million, $140.0 million and $134.0 million, respectively. In 2015 and 2014, approximately 12% and 13%, respectively, of total property and equipment (excluding accumulated depreciation) was held in

_______________
(1) This component of accumulated other comprehensive income (loss) is included in the computation of net periodic pension cost for the years ended December 31, 2015, 2014 and 2013.
Business Combinations
The purchase price of an acquisition is allocated to the underlying assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. To the extent the purchase price exceeds the fair value of the net identifiable tangible and intangible assets acquired and liabilities assumed, such excess is allocated to goodwill. The Company determines the estimated fair values after review and consideration of relevant information, including discounted cash flows, quoted market prices and estimates made by management. The Company adjusts the preliminary purchase price allocation, as necessary, during the measurement period of up to one year after the acquisition closing date as it obtains more information as to facts and circumstances existing at the acquisition date impacting asset valuations and liabilities assumed. Acquisition-related costs are recognized separately from the acquisition and are expensed as incurred.
Goodwill and Intangible Assets
Goodwill and the Company's domain name are evaluated in accordance with ASC 350-10, Goodwill and Other Intangible Assets, and an impairment analysis is conducted on an annual basis, or sooner if indicators exist for a potential impairment.
In accordance with ASC 360-10, Accounting for the Impairment or Disposal of Long-Lived Assets, long-lived assets, such as property and equipment and intangible assets, are reviewed for impairment whenever events or changes in circumstances
50
indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset.
Employee Benefits Plan
The Company sponsors a 401(k) tax-deferred savings plan for all employees in the United States who meet certain eligibility requirements. Participants may contribute up to the amount allowable as a deduction for federal income tax purposes. The Company is not required to contribute; however, the Company contributes a certain percentage of employee annual salaries on a discretionary basis, not to exceed an established threshold. In each of 2015, 2014 and 2013, the Company provided for a contribution of approximately $1.1 million.
Retirement Benefit Obligations (Pension)
The Company recognizes the over-funded or under-funded status of a defined benefit pension or post-retirement plan as an asset or liability in the accompanying consolidated balance sheets. Actuarial gains and losses are recorded in accumulated other comprehensive income (loss), a component of stockholders’ equity, and are amortized as a component of net periodic cost over the remaining estimated service period of participants.
Revenue Recognition
Product revenues consist of sales to original equipment manufacturers (OEMs), merchant power supply manufacturers and distributors. Approximately 75% of the Company’s net product sales were made to distributors in 2015. The Company applies the provisions of ASC 605-10, Revenue Recognition, and all related appropriate guidance. Revenue is recognized when all of the following criteria have been met: (1) persuasive evidence of an arrangement exists, (2) delivery has occurred, (3) the price is fixed or determinable, and (4) collectability is reasonably assured. Customer purchase orders are generally used to determine the existence of an arrangement. Delivery is considered to have occurred when title and risk of loss have transferred to the Company’s customer. The Company evaluates whether the price is fixed or determinable based on the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. With respect to collectability, the Company performs credit checks for new customers and performs ongoing evaluations of its existing customers’ financial condition and requires letters of credit whenever deemed necessary.
Sales to international OEMs and merchant power supply manufacturers for shipments from the Company’s facility outside of the United States are pursuant to “EX Works” (EXW) shipping terms, meaning that title to the product transfers to the customer upon shipment from the Company’s foreign warehouse. Sales to international OEM customers and merchant power supply manufacturers that are shipped from the Company’s facility in California are pursuant to “delivered at frontier” (DAF) shipping terms. As such, title to the product passes to the customer when the shipment reaches the destination country and revenue is recognized upon the arrival of the product in that country. Shipments to OEMs and merchant power supply manufacturers in the Americas are pursuant to “free on board” (FOB) point of origin shipping terms meaning that title is passed to the customer upon shipment. Revenue is recognized upon title transfer for sales to OEMs and merchant power supply manufacturers, assuming all other criteria for revenue recognition are met.
Sales to most of the Company's distributors are made under terms allowing certain price adjustments and rights of return on the Company's products held by its distributors. As a result of these rights, the Company defers the recognition of revenue and the costs of revenues derived from these sales until the Company's distributors report that they have sold the Company's products to their customers. The Company's recognition of such distributor revenue is based on point of sale reports received from the distributors, at which time the price is no longer subject to adjustment and is fixed, and the products are no longer subject to return to the Company except pursuant to warranty terms. The gross profit that is deferred as a result of this policy is reflected as “deferred income on sales to distributors” in the accompanying consolidated balance sheets. The total deferred revenue as of December 31, 2015, and December 31, 2014, was approximately $25.7 million and $25.0 million, respectively. The total deferred cost as of December 31, 2015, and December 31, 2014, was approximately $10.6 million and $9.8 million, respectively.
Frequently, distributors need to sell at a price lower than the standard distribution price in order to win business. At or soon after the distributor invoices its customer, the distributor submits a “ship and debit” price adjustment claim to the Company
51
to adjust the distributor's cost from the standard price to the pre-approved lower price. After verification by the Company, a credit memo is issued to the distributor for the ship and debit claim. The Company maintains a reserve for unprocessed claims and future ship and debit price adjustments. The reserves appear as a reduction to accounts receivable and deferred income on sales to distributors in the Company's accompanying consolidated balance sheets. To the extent future ship and debit claims significantly exceed amounts estimated, there could be a material impact on the deferred revenue and deferred margin ultimately recognized. To evaluate the adequacy of its reserves, the Company analyzes historical ship and debit payments and levels of inventory in the distributor channels.
Sales to certain distributors of the Company are made under terms that do not include rights of return or price concessions after the product is shipped to the distributor. Accordingly, product revenue is recognized upon shipment and title transfer assuming all other revenue recognition criteria are met.
Foreign Currency Risk and Foreign Currency Translation
As of December 31, 2015, the Company’s primary transactional currency was U.S. dollars; in addition, the Company holds cash in Swiss francs and Euros to fund the operations of the Company’s Swiss subsidiary. The foreign exchange rate fluctuation between the U.S. dollar versus the Swiss franc and Euro is recorded in other income in the consolidated statements of income.
Gains and losses arising from the re-measurement of non-functional currency balances are recorded in ''other income'' in the accompanying consolidated statements of income. For the years ended December 31, 2015, 2014 and 2013 the Company realized foreign exchange transaction gains (losses) of $(0.5) million, $0.1 million and $(0.1) million, respectively.
The functional currencies of the Company’s other subsidiaries are the local currencies. Accordingly, all assets and liabilities are translated into U.S. dollars at the current exchange rates as of the applicable balance sheet date. Revenues and expenses are translated at the average exchange rate prevailing during the period. Cumulative gains and losses from the translation of the foreign subsidiaries’ financial statements have been included in stockholders’ equity.
Warranty
The Company generally warrants that its products will substantially conform to the published specifications for 12 months from the date of shipment. The Company’s liability is limited to either a credit equal to the purchase price or replacement of the defective part. Returns under warranty have historically been immaterial, and as a result, the Company does not record a specific warranty reserve.
Advertising
Advertising costs are expensed as incurred. Advertising costs amounted to $1.1 million, $1.5 million, and $1.4 million, in 2015, 2014 and 2013, respectively.
Research and Development
Research and development costs are expensed as incurred.
Income Taxes
Income tax expense is an estimate of current income taxes payable or refundable in the current fiscal year based on reported income before income taxes. Deferred income taxes reflect the effect of temporary differences and carry-forwards that are recognized for financial reporting and income tax purposes.
The Company accounts for income taxes under the provisions of ASC 740, Income Taxes. Under the provisions of ASC 740, deferred tax assets and liabilities are recognized based on the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, utilizing the tax rates that are expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company recognizes valuation allowances to reduce any deferred tax assets to the amount that it estimates will more likely than not be realized based on available evidence and management’s judgment. The Company limits the deferred tax assets recognized related to certain officers’
52
compensation to amounts that it estimates will be deductible in future periods based upon Internal Revenue Code Section 162(m). In the event that the Company determines, based on available evidence and management judgment, that all or part of the net deferred tax assets will not be realized in the future, it would record a valuation allowance in the period the determination is made. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with the Company’s expectations could have a material impact on the Company’s results of operations and financial position.
The Company engages in qualifying activities for R&D credit purposes. On December 18, 2015, the Protecting Americans From Tax Hikes Act of 2015 was signed into law, permanently extending the federal R&D credit.
During 2014, the Company settled with the IRS and closed out the examination of its income tax returns for the years 2007 through 2009. The resolution of the audit resulted in a federal tax benefit to the Company of $2.8 million; the Company also recorded a state tax benefit of approximately $0.5 million. The agreement with IRS also allowed the Company to repatriate $5.0 million from its foreign subsidiary without incurring additional U.S. income taxes.
Common Stock Repurchases and Common Stock Dividend
In October 2012, the Company’s board of directors authorized the use of $50.0 million for the repurchase of the Company’s common stock. In 2014 and 2015, the Company’s board of directors authorized the use of an additional $75.0 million and $60.0 million, respectively, for repurchase of the Company’s common stock, with repurchases to be executed according to pre-defined price/volume guidelines. No Shares were repurchased during the year ended December 31, 2013, as the stock price levels exceeded the pre-defined price guidelines mentioned above. In 2014, the Company purchased 1.6 million shares for approximately $80.8 million. In 2015, the Company purchased 1.3 million shares for $53.7 million. As of December 31, 2015, the Company had $30.0 million available for future stock repurchases. Authorization of future stock repurchase programs is at the discretion of the board of directors and will depend on the Company's financial condition, results of operations, capital requirements, business conditions as well as other factors.
The following table presents the quarterly dividends declared on the Company’s common stock for the periods indicated:
Year Ended December 31, | |||||||||||
2015 | 2014 | 2013 | |||||||||
First Quarter | $ | 0.12 | $ | 0.10 | $ | 0.08 | |||||

Third Quarter | $ | 0.12 | $ | 0.12 | $ | 0.08 | |||||

The Company paid a total of approximately $13.9 million, $13.2 million and $9.4 million in cash dividends during 2015, 2014 and 2013, respectively.
In January 2016, the Company’s board of directors declared a $0.13 quarterly dividend for each quarter in 2016. The declaration of any future cash dividend is at the discretion of the board of directors and will depend on the Company’s financial condition, results of operations, capital requirements, business conditions and other factors, as well as a determination that cash dividends are in the best interest of the Company’s stockholders.
Indemnifications
The Company sells products to its distributors under contracts, collectively referred to as Distributor Sales Agreements (DSA). Each DSA contains the relevant terms of the contractual arrangement with the distributor, and generally includes certain provisions for indemnifying the distributor against losses, expenses, and liabilities from damages that may be awarded against the distributor in the event the Company’s products are found to infringe upon a patent, copyright, trademark, or other proprietary right of a third party (Customer Indemnification). The DSA generally limits the scope of and remedies for the Customer Indemnification obligations in a variety of industry-standard respects, including, but not limited to, limitations based on time and
53
geography, and a right to replace an infringing product. The Company also, from time to time, has granted a specific indemnification right to individual customers.
The Company believes its internal development processes and other policies and practices limit its exposure related to such indemnifications. In addition, the Company requires its employees to sign a proprietary information and inventions agreement, which assigns the rights to its employees' development work to the Company. To date, the Company has not had to reimburse any of its distributors or customers for any losses related to these indemnifications and no material claims were outstanding as of December 31, 2015. For several reasons, including the lack of prior indemnification claims and the lack of a monetary liability limit for certain infringement cases, the Company cannot determine the maximum amount of potential future payments, if any, related to such indemnifications.
Recently Issued Accounting Pronouncements
In May 2014, the FASB amended the existing accounting standards for revenue recognition, ASU 2014-09, Revenue from Contracts with Customers. The amendments are based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company is required to adopt the amendments in the first quarter of 2018. Early adoption is permitted; however, the Company is not permitted to adopt the standard earlier than January 1, 2017. The amendments may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. The Company is currently evaluating the impact of these amendments and the transition alternatives on its consolidated financial statements.
In July 2015, the FASB amended the existing accounting standards for the measurement of inventory, ASU 2015-11, Inventory. The amendments require inventory to 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. The Company is required to adopt the amendments in the first quarter of 2017. The amendments should be applied prospectively with early adoption permitted as of the beginning of an interim or annual reporting period. The Company does not expect that the adoption of these amendments will have a material impact on its consolidated financial statements.
In November 2015, the FASB issued new guidance on the classification of deferred tax assets and liabilities, ASU 2015-17, Balance Sheet Classification of Deferred Taxes. The new guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as non-current on the balance sheet. The Company early adopted the new guidance as of the beginning of the year ended December 31, 2015 and have applied the amendments on a prospective basis. All deferred tax assets and liabilities as of December 31, 2015, have been classified as non-current in the Consolidated Balance Sheets and the Notes to Consolidated Financial Statements in this Form 10-K. The adoption as of the beginning of the year resulted in a $2.2 million decrease to deferred tax liabilities, a $1.3 million decrease to non-current deferred assets and $0.9 million increase to non-current tax liabilities. No prior periods were retrospectively adjusted.
3. STOCK PLANS AND SHARE BASED COMPENSATION:
Stock Plans
As of December 31, 2015, the Company had two stock-based compensation plans (the “Plans”) which are described below.
2007 Equity Incentive Plan
The 2007 Equity Incentive Plan (2007 Plan) was adopted by the board of directors on September 10, 2007, and approved by the stockholders on November 7, 2007, as an amendment and restatement of the 1997 Stock Option Plan (1997 Plan). The 2007 Plan provides for the grant of incentive stock options, non-statutory stock options, restricted stock awards, restricted stock unit (RSU) awards, stock appreciation rights, performance-based (PSU) awards, long-term performance based (PRSU) awards and other stock awards to employees, directors and consultants. As of December 31, 2015, the total maximum remaining number of shares that may be issued under the 2007 Plan was 4.7 million shares, which includes 0.9 million options issued but not exercised and 1.6 million awards granted but unvested. As of December 31, 2015, 2.1 million shares of common stock remain available for future grant under the 2007 Plan. Pursuant to the 2007 Plan, the exercise price for incentive stock options and non-statutory stock
54
options is generally at least 100% of the fair market value of the underlying shares on the date of grant. Options generally vest over 48 months measured from the date of grant. Options generally expire no later than ten years after the date of grant, subject to earlier termination upon an optionee’s cessation of employment or service.
Beginning January 27, 2009, grants pursuant to the Directors Equity Compensation Program (which was adopted by the board of directors on January 27, 2009) to non-employee directors have been made primarily under the 2007 Plan. The Directors Equity Compensation Program provides for grants to outside directors as follows: effective annually, upon the first trading day of July, each outside director would receive a grant of an equity award with an aggregate value of $100,000. At each outside director’s election, such award would consist entirely of RSUs or entirely of stock options. The quantity of options would be calculated by dividing $100,000 by the Black-Scholes value on the date of grant. The quantity of RSUs issued would be calculated by dividing $100,000 by the grant date fair value. Further, on the date of election of a new outside director, such new director would receive such grant as continuing outside directors receive on the first trading day of July; provided, however, that such grant is prorated for the portion of the year that such new outside director will serve until the next first trading day of July. The Directors Equity Compensation Program will remain in effect at the discretion of the board of directors or the compensation committee.
On July 28, 2009, the 2007 Plan was amended generally to prohibit outstanding options or stock appreciation rights from being canceled in exchange for cash without stockholder approval.
1997 Employee Stock Purchase Plan
Under the 1997 Employee Stock Purchase Plan (Purchase Plan), eligible employees may apply accumulated payroll deductions, which may not exceed 15% of an employee’s compensation, to the purchase of shares of the Company’s common stock at periodic intervals. The purchase price of stock under the Purchase Plan is equal to 85% of the lower of (i) the fair market value of the Company’s common stock on the first day of each offering period, or (ii) the fair market value of the Company’s common stock on the purchase date (as defined in the Purchase Plan). Each offering period consists of one purchase period of approximately six months duration. An aggregate of 3.0 million shares of common stock were reserved for issuance to employees under the Purchase Plan. As of December 31, 2015, of the shares reserved for issuance, 2.8 million shares had been purchased and 0.2 million shares were reserved for future issuance under the Purchase Plan.
Shares Reserved
As of December 31, 2015, the Company had approximately 2.4 million shares of common stock reserved for future grant under all stock plans.
Stock-Based Compensation
The Company applies the provisions of ASC 718-10, Stock Compensation. Under the provisions of ASC 718-10, the Company recognizes the fair value of stock-based compensation in its financial statements over the requisite service period of the individual grants, which generally equals a four-year vesting period. The Company uses estimates of volatility, expected term, risk-free interest rate, dividend yield and forfeitures in determining the fair value of these awards and the amount of compensation expense to recognize. The Company uses the straight-line method to amortize all stock awards granted over the requisite service period of the award.

PSU Awards
Under the performance-based awards program, the Company grants awards in the performance year in an amount equal to twice the target number of shares to be issued if the maximum performance metrics are met. The number of shares that are released at the end of the performance year can range from zero to 200% of the target number depending on the Company’s performance. The performance metrics of this program are annual targets consisting of a combination of net revenue, non-GAAP operating earnings and strategic goals. Each performance-based award share granted from the 2007 Plan will reduce the number of shares available for issuance under the 2007 Plan by two shares.
During the year ended December 31, 2015, the Company issued approximately 89,000 PSUs to employees and executives. As the net revenue, non-GAAP operating income and strategic goals are considered performance conditions, expense associated with these awards, net of estimated forfeitures, is recognized over the service period based on an assessment of the achievement of the performance targets. The fair value of these PSUs is determined using the fair value of the Company’s common stock on the date of the grant, reduced by the discounted present value of dividends expected to be declared before the awards vest. If the
57
performance conditions are not achieved, no compensation cost is recognized and any previously recognized compensation is reversed.
In January 2015, it was determined that the Company had not reached the minimum level of the established 2014 performance targets (consisting of revenue and non-GAAP operating income). Accordingly, no shares subject to PSUs granted in connection with the 2014 performance based incentive plan were released to the Company’s employees and executives in 2015.
A summary of PSU awards outstanding as of December 31, 2015, and activity during the three years then ended is presented below:
(shares and intrinsic value in thousands) | Shares | Weighted Average Grant Date Fair Value Per Share | Weighted Average Remaining Contractual Term (in years) | Aggregate Intrinsic Value | ||||||||

There were no PSU awards released in the year ended December 31, 2015 (as the Company did not reach its performance goals established for the 2014 PSUs). The grant date fair value of PSU awards released, which were fully vested, in the years ended December 31, 2014 and 2013, was approximately $3.2 million and $2.0 million, respectively.
PRSU Awards (Long-term Performance Based)
In the first quarter of 2014 the Company began granting PRSU awards. The Company's PRSU program provides for the issuance of PRSUs which will vest based on the Company's performance measured against the PRSU Plan's established revenue targets. The PRSUs were granted in an amount equal to twice the target number of shares to be issued if the maximum performance metrics are met. The actual number of shares the recipient receives is determined at the end of a three-year performance period based on results achieved versus the Company’s performance goals, and may range from zero to 200% of the target number. The performance goals for PRSUs granted in fiscal 2014 and 2015 were based on the Company’s annual revenue growth over the respective three-year performance period. Each PRSU granted from the 2007 Plan will reduce the number of shares available for issuance under the 2007 Plan by two shares.
Recipients of a PRSU award generally must remain employed by the Company on a continuous basis through the end of the applicable three-year performance period in order to receive shares subject to that award. Expenses associated with these awards, net of estimated forfeitures, are recorded throughout the year depending on the number of shares expected to vest based on progress toward the performance target. The fair value of PRSU awards is determined using the fair value of the Company’s common stock on the grant date, reduced by the discounted present value of dividends expected to be declared before the awards
58
vest. If the performance conditions are not achieved, no compensation cost is recognized and any previously recognized compensation is reversed.
A summary of PRSU awards outstanding as of December 31, 2015, and activity during the years ended December 31, 2015 and 2014, are presented below:

RSU Awards
The Company grants restricted stock units to employees under the 2007 Plan. RSUs granted to employees typically vest ratably over a four-year period, and are converted into shares of the Company’s common stock upon vesting on a one-for-one basis subject to the employee’s continued service to the Company over that period. The fair value of RSUs is determined using the fair value of the Company’s common stock on the date of the grant, reduced by the discounted present value of dividends expected to be declared before the awards vest. Compensation expense is recognized on a straight-line basis over the requisite service period of each grant adjusted for estimated forfeitures. Each RSU award granted from the 2007 plan will reduce the number of shares available for issuance under the 2007 Plan by two shares.
A summary of RSUs outstanding as of December 31, 2015, and activity during the three years then ended, is as follows:
(shares and intrinsic value in thousands) | Shares | Weighted Average Grant Date Fair Value Per Share | Weighted Average Remaining Contractual Term (in years) | Aggregate Intrinsic Value | ||||||||

The grant date fair value of RSUs vested in the years ended December 31, 2015, 2014 and 2013, was approximately $11.3 million, $10.3 million and $7.4 million, respectively.
4. FAIR VALUE MEASUREMENTS:
ASC 820-10, Fair Value Measurements, clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820-10 establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices for identical assets in active markets; (Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.
The Company's cash and investment instruments are classified within Level 1 or Level 2 of the fair-value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The type of instrument valued based on quoted market prices in active markets primarily includes money market securities. This type of instrument is generally classified within Level 1 of the fair-value hierarchy. The types of instruments valued based on other observable inputs (Level 2 of the fair-value hierarchy) include investment-grade corporate bonds and government, state, municipal and provincial obligations. Such types of investments are valued by using a multi-dimensional relational model, the inputs are primarily benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research publications.
The Company principally holds securities until maturity; however, they may be sold under certain circumstances, including, but not limited to, the funding of acquisitions and other strategic investments. Accordingly, the Company classified its investment portfolio as available-for-sale as of December 31, 2015 and December 31, 2014.
The fair value hierarchy of the Company’s cash equivalents and marketable securities at December 31, 2015, and December 31, 2014, was as follows:

The Company did not transfer any investments between level 1 and level 2 of the fair value hierarchy in the years ended December 31, 2015, and December 31, 2014.
5. GOODWILL AND INTANGIBLE ASSETS:
Goodwill increased during the year ended December 31, 2015, due to the Company's acquisition of Cambridge Semiconductor Limited (CamSemi) (refer to Note 11, Acquisitions, for details on the Company’s CamSemi acquisition). Changes in the carrying amount of goodwill during the years ended December 31, 2015 and 2014, are as follows:
(in thousands) | Goodwill | ||
Balance at December 31, 2013 | $ | 80,599 | |
Goodwill acquired during the period | — | ||
Balance at December 31, 2014 | 80,599 | ||
Goodwill acquired during the period | 11,250 | ||
Balance at December 31, 2015 | $ | 91,849 | |
Intangible assets consist primarily of developed technology, acquired licenses, customer relationships, trade name, domain name, in-process R&D and patent rights, and are reported net of accumulated amortization. In January 2015, the Company acquired CamSemi, resulting in the addition of the following intangible assets: developed technology of $6.6 million, which will be amortized over a period of three - seven years; and customer relationships of $2.4 million, which will be amortized over a period of five years. In August 2015, the Company purchased a building with existing third-party leases, resulting in the addition of in-place lease intangible assets of $0.7 million which will be amortized over a period of two years.
The Company amortizes the cost of all intangible assets over the shorter of the estimated useful life or the term of the developed technology, acquired licenses, customer relationships, trade name, patent rights and in-place leases, which range from two to twelve years, with the exception of $4.7 million of in-process R&D and $1.3 million paid to acquire an internet domain name. In-process R&D is assessed for impairment until the development is completed and products are available for sale, at which time the Company will begin to amortize the in-process R&D. The Company does not expect the amortization of in-process R&D to begin in 2016. The Company acquired the rights to the internet domain name www.power.com, which is now the Company’s primary domain name; the cost to acquire the domain name has been recorded as an intangible asset and will not be amortized as it has an indefinite useful life. Amortization of acquired intangible assets was approximately $7.0 million, $6.1 million and $7.4 million in the years ended December 31, 2015, 2014 and 2013, respectively. The Company does not believe there is any significant residual value associated with the following intangible assets:

With respect to trade receivables, the Company performs ongoing evaluations of its customers' financial conditions and requires letters of credit whenever deemed necessary. Additionally, the Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical trends related to past write-offs and other relevant information. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers. Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash investments and trade receivables. As of December 31, 2015, and December 31, 2014, 66% of accounts receivable were concentrated with the Company’s top 10 customers.

7. EARNINGS PER SHARE:
Basic earnings per share are calculated by dividing net income by the weighted-average shares of common stock outstanding during the period. Diluted earnings per share are calculated by dividing net income by the weighted-average shares of common stock and dilutive common equivalent shares outstanding during the period. Dilutive common equivalent shares included in this calculation consist of dilutive shares issuable upon the assumed exercise of outstanding common stock options, the assumed vesting of outstanding restricted stock units and performance based awards, and the assumed issuance of awards under the stock purchase plan, as computed using the treasury stock method.
A summary of the earnings per share calculation is as follows:

(1) | The Company includes the shares underlying performance-based awards in the calculation of diluted earnings per share if the performance conditions have been satisfied as of the end of the reporting period and excludes such shares when the necessary conditions have not been met. The Company has excluded all performance-based awards in the 2014 calculation as the performance conditions for those awards were not met as of the end of the period. The Company has included in the 2015 and 2013 calculations those shares that were contingently issuable upon the satisfaction of the performance conditions as of the end of the respective periods. |
In the years ended December 31, 2015, 2014 and 2013, approximately 8,000, 37,000 and 122,000 outstanding stock awards were determined to be anti-dilutive, respectively, and therefore were excluded from the computation of diluted earnings per share.
8. PROVISION FOR INCOME TAXES:
Income Taxes
The Company accounts for income taxes under the provisions of ASC 740, Income Taxes. Under the provisions of ASC 740, deferred tax assets and liabilities are recognized based on the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, utilizing the tax rates that are expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.
U.S. and foreign components of income before income taxes were:

The Company is entitled to a deduction for federal and state tax purposes with respect to employees' stock option activity. The net reduction in taxes otherwise payable in excess of any amount credited to income tax expense has been reflected as an adjustment to additional paid-in capital. For 2015, 2014 and 2013, the benefit (deficiency) arising from employee stock option activity that resulted in an adjustment to additional paid in capital was approximately $(0.2) million, $0.8 million and $1.3 million, respectively.
The provision for (benefit from) income taxes differs from the amount, which would result by applying the applicable federal income-tax rate to income before provision for (benefit from) income taxes, as follows:

The effective tax rate for the year ended December 31, 2015 was favorably impacted by the geographic distribution of the Company’s world-wide earnings in lower-tax jurisdictions. Additionally, the rate was favorably impacted by the federal R&D tax credit which was extended permanently when the Protecting Americans From Tax Hikes Act was signed into law on December 18, 2015.
The Company reached a settlement with the IRS in the quarter ended June 30, 2014, to close out the examination of its federal income-tax returns for the years 2007 through 2009. As a result, the Company adjusted its tax balances and the provision for income tax for the year ended December 31, 2014, includes a one-time benefit of $3.3 million comprising $2.8 million in
65
federal income taxes and interest, and state income taxes of approximately $0.5 million. The one-time benefit includes the reversal of $4.1 million of related unrecognized tax benefits that had been recorded as non-current liabilities in the Company’s consolidated balance sheets. The Company has now concluded all U.S. federal income-tax matters for the years through 2009.
The effective tax rate for the year ended December 31, 2013, was favorably impacted by the geographic distribution of the Company's world-wide earnings and earnings in lower-tax jurisdictions. Additionally, the rate was favorably impacted by federal research tax credits both for 2013 and 2012.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities and projected future taxable income. In the event that the Company determines, based on available evidence and management judgment, that all or part of the net deferred tax assets will not be realized in the future, the Company would record a valuation allowance in the period the determination is made. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with the Company’s expectations could have a material impact on its results of operations and financial position.
As of December 31, 2015, the Company continues to maintain a valuation allowance primarily as a result of capital losses for federal purposes, and on its California deferred tax assets as the Company believes that it is not more likely than not that the deferred tax assets will be fully realized. In addition, the Company maintains a valuation allowance with respect to certain of its deferred tax assets relating to tax credits in Canada and the state of New Jersey.
As of December 31, 2015, the Company had federal research and development tax credit carry-forwards of approximately $12.7 million, which will begin to expire in 2030 if unutilized; federal net operating losses of $25.1 million, which will begin to expire in 2024 if unutilized; California research and development tax credit carry-forwards of approximately $16.6 million (there is no expiration of research and development tax credit carry-forwards for the state of California) and California net operating losses of $50.3 million which will begin to expire in 2032. As of December 31, 2015, the Company had Canadian scientific research and experimental development tax credit carry-forwards of approximately $1.9 million and New Jersey research and experimental development tax credit carry-forwards of approximately $0.6 million, which will start to expire in 2026 and 2027, respectively.
The Company does not provide for U.S. taxes on its undistributed earnings of foreign subsidiaries that it intends to invest indefinitely outside the U.S., unless such taxes are otherwise required under U.S. tax law. Beginning in 2013, the Company
66
determined that a portion of its foreign subsidiaries current and future earnings may be remitted prospectively to the U.S. for domestic cash flow purposes and, accordingly, provided for the related U.S. taxes in its consolidated financial statements. If the Company changes its intent to invest its undistributed foreign earnings indefinitely or if a greater amount of undistributed earnings are needed for U.S. operations than previously anticipated and for which U.S. taxes have not been recorded, the Company would be required to accrue or pay U.S. taxes (subject to an adjustment for foreign tax credits, where applicable) and withholding taxes payable to various foreign countries on some or all of these undistributed earnings. As of December 31, 2015, the Company had undistributed earnings of foreign subsidiaries that are indefinitely invested outside of the U.S. of approximately $222.0 million. It is not practicable to determine the income tax liability that might be incurred if these earnings were to be distributed.
Unrecognized Tax Benefits
The Company applies the provisions of ASC 740-10, relating to accounting for uncertain income taxes. Reconciliation of the beginning and ending amount of unrecognized tax benefits:

The Company's total unrecognized tax benefits as of December 31, 2015, 2014 and 2013, was $13.6 million, $11.2 million and $12.7 million, respectively. An income-tax benefit of $5.6 million, net of valuation allowance adjustments, would be recorded if these unrecognized tax benefits are recognized. The Company cannot reasonably estimate the amount of the unrecognized tax benefit that could be adjusted in the next twelve months.
The Company’s continuing practice is to recognize interest and/or penalties related to income-tax matters in income-tax expense. The Company has accrued interest and penalties at December 31, 2015, and December 31, 2014, of $0.1 million and $0.1 million, respectively, which have been recorded in long-term income taxes payable in the accompanying Consolidated Balance Sheets.
In July 2013, the FASB issued a new accounting standard that requires the presentation of certain unrecognized tax benefits as reductions to deferred tax assets rather than as liabilities in the Company’s consolidated balance sheets when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The Company adopted this new standard on a prospective basis in the first quarter of 2014. The impact of the adoption was a reduction to long-term deferred tax assets and non-current income tax payable of approximately $4.3 million.
As of December 31, 2015, the Company has concluded all U.S. federal income tax matters for the years through 2009, and has finalized Swiss income tax returns for the years through 2012. There is currently no pending income tax audit.

On July 27, 2015, in Altera Corp. v. Commissioner, the U.S. Tax Court issued an opinion related to the treatment of stock-based compensation expense in an intercompany cost-sharing arrangement. A final decision has yet to be issued by the Tax Court due to other outstanding issues related to the case. At this time, the U.S. Department of the Treasury has not withdrawn the requirement to include stock-based compensation expense from IRS cost-sharing regulations. The Company has reviewed this case and its impact and concluded that no adjustment to the consolidated financial statements is appropriate at this time. The Company will continue to monitor ongoing developments and potential impacts to the consolidated financial statements.
9. COMMITMENTS:

10. LEGAL PROCEEDINGS AND CONTINGENCIES:
From time to time in the ordinary course of business, the Company becomes involved in lawsuits, or customers and distributors may make claims against the Company. In accordance with ASC 450-10, Contingencies, the Company makes a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated.
On October 20, 2004, the Company filed a complaint against Fairchild Semiconductor International, Inc. and Fairchild Semiconductor Corporation (referred to collectively as “Fairchild”) in the United States District Court for the District of Delaware. In its complaint, the Company alleged that Fairchild has and is infringing four of Power Integrations’ patents pertaining to pulse width modulation (PWM) integrated circuit devices. Fairchild denied infringement and asked for a declaration from the court that it does not infringe any Power Integrations patent and that the patents are invalid. The Court issued a claim construction order on March 31, 2006 which was favorable to the Company. The Court set a first trial on the issues of infringement, willfulness and damages for October 2, 2006. At the close of the first trial, on October 10, 2006, the jury returned a verdict in favor of the Company finding all asserted claims of all four patents-in-suit to be willfully infringed by Fairchild and awarding $34.0 million in damages.
68
Fairchild raised defenses contending that the asserted patents are invalid or unenforceable, and the Court held a second trial on these issues beginning on September 17, 2007. On September 21, 2007, the jury returned a verdict in the Company’s favor, affirming the validity of the asserted claims of all four patents-in-suit. Fairchild submitted further materials on the issue of enforceability along with various other post-trial motions, and the Company filed post-trial motions seeking a permanent injunction and increased damages and attorneys’ fees, among other things. On September 24, 2008, the Court denied Fairchild’s motion regarding enforceability and ruled that all four patents are enforceable. On December 12, 2008, the Court ruled on the remaining post-trial motions, including granting a permanent injunction, reducing the damages award to $6.1 million, granting Fairchild a new trial on the issue of willful infringement in view of an intervening change in the law, and denying the Company’s motion for increased damages and attorneys’ fees with leave to renew the motion after the resolution of the issue of willful infringement. On December 22, 2008, at Fairchild’s request, the Court temporarily stayed the permanent injunction for 90 days. On January 12, 2009, Fairchild filed a notice of appeal challenging the Court’s refusal to enter a more permanent stay of the injunction, and Fairchild filed additional motions requesting that both the Federal Circuit and the District Court extend the stay of injunction. The District Court temporarily extended the stay pending the Federal Circuit ruling on Fairchild’s pending motion, but the Federal Circuit dismissed Fairchild’s appeal and denied its motion on May 5, 2009, and the District Court issued an order on May 13, 2009 confirming the reinstatement of the permanent injunction as originally entered in December 2008. On June 22, 2009, the Court held a brief bench re-trial on the issue of willful infringement. On July 22, 2010, the Court found that Fairchild willfully infringed all four of the asserted patents, and the Court also invited briefing on enhanced damages and attorneys’ fees. Fairchild also filed a motion requesting that the Court amend its findings regarding willfulness. On January 18, 2011, the Court denied Fairchild’s request to amend the findings regarding Fairchild’s willful infringement and doubled the damages award against Fairchild but declined to award attorneys’ fees. On February 3, 2011, the Court entered final judgment in favor of the Company for a total damages award of $12.9 million. Fairchild filed a notice of appeal challenging the final judgment and a number of the underlying rulings, and the Company filed a cross-appeal seeking to increase the damages award. The appeal was argued on January 11, 2012, and the Federal Circuit issued a mixed ruling on March 26, 2013, affirming Fairchild’s infringement of certain claims that support the basis for the permanent injunction while reversing, vacating, and remanding the findings with respect to other claims, including the Company’s claim for damages. The Company filed a petition seeking Supreme Court review of the Federal Circuit’s ruling on damages issues, and the Supreme Court called for a response from Fairchild but ultimately declined to review the case. On remand, the Company intends to pursue its claim for financial compensation based on Fairchild’s infringement.
On May 9, 2005, the Company filed a Complaint with the U.S. International Trade Commission (ITC) under section 337 of the Tariff Act of 1930, as amended, 19 U.S.C. Section 1337 against System General (SG). The Company filed a supplement to the complaint on May 24, 2005. The Company alleged infringement of its patents pertaining to PWM integrated circuit devices produced by SG, which are used in power conversion applications such as power supplies for computer monitors. The Commission instituted an investigation on June 8, 2005 in response to the Company’s complaint. SG filed a response to the ITC complaint asserting that the patents-in-suit were invalid and not infringed. The Company subsequently and voluntarily narrowed the number of patents and claims in suit, which proceeded to a hearing. The hearing on the investigation was held before the Administrative Law Judge (ALJ) from January 18 to January 24, 2006. Post-hearing briefs were submitted and briefing concluded February 24, 2006. The ALJ’s initial determination was issued on May 15, 2006. The ALJ found all remaining asserted claims valid and infringed, and recommended the exclusion of the infringing products as well as certain downstream products that contain the infringing products. After further briefing, on June 30, 2006, the Commission decided not to review the initial determination on liability, but did invite briefs on remedy, bonding and the public interest. On August 11, 2006, the Commission issued an order excluding from entry into the United States the infringing SG PWM chips, and any liquid-crystal-display (LCD) computer monitors, AC printer adapters and sample/demonstration circuit boards containing an infringing SG chip. The U.S. Customs Service is authorized to enforce the exclusion order. On October 11, 2006, the presidential review period expired without any action from the President, and the ITC exclusion order is now in full effect. SG appealed the ITC decision, and on November 19, 2007, the Federal Circuit affirmed the ITC’s findings in all respects. On October 27, 2008, SG filed a petition to modify the exclusion order in view of a recent Federal Circuit opinion in an unrelated case, and the Company responded to oppose any modification, but the Commission modified the exclusion order on February 27, 2009. Nevertheless, the exclusion order still prohibits SG and related entities from importing the infringing SG chips and any LCD computer monitors, AC printer adapters, and sample/demonstration circuit boards containing an infringing SG chip.
On May 23, 2008, the Company filed a complaint against Fairchild Semiconductor International, Inc., Fairchild Semiconductor Corporation, and Fairchild’s wholly owned subsidiary System General Corporation (referred to collectively as “Fairchild”), in the United States District Court for the District of Delaware. In its complaint, the Company alleged that Fairchild has infringed and is infringing three patents pertaining to power supply controller integrated circuit devices. Fairchild answered the Company’s complaint on November 7, 2008, denying infringement and asking for a declaration from the Court that it does
69
not infringe any Power Integrations patent and that the patents are invalid and unenforceable. Fairchild’s answer also included counterclaims accusing the Company of infringing three patents pertaining to primary side power conversion integrated circuit devices. Fairchild had earlier brought these same claims in a separate suit against the Company, also in Delaware, which Fairchild dismissed in favor of adding its claims to the Company’s already pending suit against Fairchild. The Company has answered Fairchild’s counterclaims, denying infringement and asking for a declaration from the Court that it does not infringe any Fairchild patent and that the Fairchild patents are invalid. Fairchild also filed a motion to stay the case, but the Court denied that motion on December 19, 2008. On March 5, 2009, Fairchild filed a motion for summary judgment to preclude any recovery for post-verdict sales of parts found to infringe in the parties’ other ongoing litigation, described above, and the Company filed its opposition and a cross-motion to preclude Fairchild from re-litigating the issues of infringement and damages for those same products. On June 26, 2009, the Court held a hearing on the parties’ motions, and on July 9, 2009 the Court issued an order denying the parties’ motions but staying proceedings with respect to the products that were found to infringe and which are subject to the injunction in the other Delaware case between the parties pending the entry of final judgment in that case; those products are expected to be addressed in the context of the parties’ remand proceedings following the appeal in their earlier litigation in Delaware, and the remainder of the case is proceeding. On December 18, 2009, the Court issued an order construing certain terms in the asserted claims of the Company’s and Fairchild’s patents in suit. Following the Court’s ruling on claim construction, Fairchild withdrew its claim related to one of its patents and significantly reduced the number of claims asserted for the remaining two patents. The parties thereafter filed and argued a number of motions for summary judgment, and the Court denied the majority of the parties’ motions but granted the Company’s motion to preclude Fairchild from re-arguing validity positions that were rejected in the prior case between the parties. Because the assigned Judge retired at the end of July 2010, the case was re-assigned to a different Judge, and the Court vacated the trial schedule and had the parties provide their input on the appropriate course of action. The Court thereafter set a trial schedule with the jury trial on infringement and validity to begin in July 2011. On April 18, 2011, the Court rescheduled the trial to begin in January 2012, and on June 2, 2011, the Court moved the trial date to April 2012 to permit the parties to address another patent the Company accused Fairchild of infringing. Following a trial in April 2012, the jury returned a verdict finding that Fairchild infringes two of the Company’s patents, that Fairchild has induced others to infringe the Company’s patents, and also upheld the validity of the infringed patents. Of the two remaining counterclaim patents Fairchild asserted in the case, one was found not to be infringed, but the jury found the second patent to be infringed by a limited number of the Company’s products, although the jury further found the Company did not induce infringement by any customers, including customers outside the United States. On March 29, 2013, the District Court denied most of the parties’ post-trial motions on liability but granted the Company’s motion for judgment as a matter of law finding that Fairchild infringed another of the Company’s patents. On April 25, 2013, the Court denied both parties’ motions regarding the unenforceability of each other’s patents. The Company is challenging adverse findings on appeal; nevertheless, the Company estimates that even if the verdict on Fairchild’s patent were ultimately upheld, the sales potentially impacted would amount to only about 0.3% of the Company’s revenues. The Company requested an injunction preventing further infringement of its own patents by Fairchild, and Fairchild requested an injunction as well. Following a hearing on the issue in June 2014, the Court denied Fairchild’s request for an injunction against the Company and granted the Company’s request for an injunction against Fairchild. On January 13, 2015, the District Court entered final judgment on the liability and validity issues discussed above, and both parties filed appeals with the Federal Circuit; briefing and oral argument on the appeal should be completed in 2016. The Company is also seeking financial damages, as well as enhanced damages for willful infringement, issues to be decided in separate proceedings at a later date.
On June 28, 2004, the Company filed a complaint for patent infringement in the U.S. District Court, Northern District of California, against SG Corporation, a Taiwanese company, and its U.S. subsidiary. The Company’s complaint alleged that certain integrated circuits produced by SG infringed and continue to infringe certain of its patents. On June 10, 2005, in response to the initiation of the International Trade Commission (ITC) investigation discussed above, the District Court stayed all proceedings. Subsequent to the completion of the ITC proceedings, the District Court temporarily lifted the stay and scheduled a case management conference. On December 6, 2006, SG filed a notice of appeal of the ITC decision as discussed above. In response, and by agreement of the parties, the District Court vacated the scheduled case management conference and renewed the stay of proceedings pending the outcome of the Federal Circuit appeal of the ITC determination. On November 19, 2007, the Federal Circuit affirmed the ITC’s findings in all respects, and SG did not file a petition for review. The parties subsequently filed a motion to dismiss the District Court case without prejudice. On November 4, 2009, the Company re-filed its complaint for patent infringement against SG and its parent corporations, Fairchild Semiconductor International, Inc. and Fairchild Semiconductor Corporation, to address their continued infringement of patents at issue in the original suit that recently emerged from SG requested reexamination proceedings before the U.S. Patent and Trademark Office (USPTO). The Company seeks, among other things, an order enjoining SG and Fairchild from infringing the Company’s patents and an award of damages resulting from the alleged infringement. Fairchild has denied infringement and asked for a declaration from the Court that it does not infringe any Power Integrations patent, that the patents are invalid, and that one of the two of the Company’s patents now at issue in the case is unenforceable. On May 5,
70
2010, SG and Fairchild filed an amended answer including counterclaims accusing the Company of infringing two patents, and since that time Fairchild has withdrawn its claim for infringement of one of the patents it originally asserted against the Company but added another patent to the case over the Company’s objections; the Company contests these claims vigorously. Both parties filed summary judgment motions and challenges to each other’s experts’ testimony, and the Court granted the Company’s motion for summary judgment of non-infringement with respect to one of Fairchild’s two patents. Following a trial on the remaining claims in February 2014, the jury returned a verdict in the Company’s favor, affirming the validity of the asserted claims of the Company’s patents-in-suit, finding that SG and Fairchild infringed the Company’s asserted patents and induced infringement by others, and awarding $105.0 million in damages. The Jury also rejected Fairchild’s remaining counterclaims for infringement against the Company. Fairchild challenged these rulings in post-trial motions, but the judge confirmed the jury’s determinations on infringement and damages, although the Court declined to find Fairchild’s infringement willful. Fairchild also pressed its unenforceability claim with respect to one of the two patents it was found to infringe in post-trial briefing, but the Court rejected Fairchild’s unenforceability claim. Fairchild also requested reconsideration of the damages determinations, and the Court granted a new trial with respect to damages but none of the other issues addressed in the previous trial, with the retrial scheduled for December 2015. Thereafter, the parties completed pretrial proceedings challenging each other’s experts, and the Court granted portions of each party’s motions limiting the scope of expert testimony for purposes of the damages retrial, but neither party was successful in their efforts to prevent the other side’s experts from testifying at trial. Following a retrial on the issue of damages in December 2015, the jury returned a verdict in the Company’s favor, finding that the Company’s patented technology created the basis for customer demand for the infringing Fairchild products and awarding $139.8 million in damages. Although the jury awarded damages, at this stage of the proceedings the Company cannot state the amount, if any, it might ultimately recover from Fairchild, and no benefits have been recorded in the Company’s consolidated financial statements as a result of the damages verdict. The Company has also filed a motion requesting enhanced damages and attorney fees and intends to request an injunction to prevent further infringement. Fairchild has stated that it intends to challenge the verdict; briefing on post-trial motions is expected to take place over the coming months.
In February 2010, Fairchild and System General (SG) filed suits for patent infringement against the Company, Power Integrations Netherlands B.V., and representative offices of Power Integrations Netherlands in Shanghai and Shenzhen with the Suzhou Intermediate Court in the People’s Republic of China. The suits assert four Chinese patents and seek an injunction and damages of approximately $19.0 million. Power Integrations Netherlands filed invalidation proceedings for all four asserted SG patents in the People’s Republic of China Patent Reexamination Board (PRB) of the State Intellectual Property Office (SIPO), and all four challenges were accepted by the PRB, with hearings conducted in September 2010. In early January 2012, the Company received rulings from the PRB invalidating the majority of the claims Fairchild asserted in litigation. The Suzhou Court conducted evidentiary hearings in 2012 and issued rulings in late December 2012, finding that the Company did not infringe any of the asserted patents. Fairchild filed appeals challenging the Suzhou Court’s non-infringement rulings, and the appeals court in Nanjing held further hearings in the infringement proceedings in late 2014, but Fairchild has since dismissed its appeals, bringing the infringement proceedings to a close in the first quarter of 2015.
On July 11, 2011, the Company filed a complaint in the U.S. District Court, District of Columbia, against David Kappos in his capacity as Director of the United States Patent and Trademark Office (PTO) as part of the ongoing reexamination proceedings related to one of the patents asserted against Fairchild and SG in the Delaware litigation described above. The Company filed a motion for summary judgment on a preliminary jurisdictional issue, and the PTO filed a cross-motion to dismiss on this same issue; briefing on those motions was completed in October, 2011. On November 18, 2013, the Court granted the PTO’s motion and transferred the case to the Federal Circuit, where additional briefing took place. Following a hearing in May 2015, the Federal Circuit ruled in the Company’s favor on August 12, 2015, overturning the PTO’s claim construction and remanding the case for further proceedings.
On May 1, 2012, Fairchild Semiconductor Corporation and Fairchild's wholly-owned subsidiary, System General Corporation (referred to collectively as “Fairchild”), filed a complaint against the Company in the United States District Court for the District of Delaware. In its complaint, Fairchild alleged that the Company has infringed and is infringing four patents pertaining to power conversion integrated circuit devices. The Company answered Fairchild’s complaint, denying infringement and asking for a declaration from the Court that it does not infringe any Fairchild patent and that the Fairchild patents are invalid, and the Company also asserted counterclaims against Fairchild for infringement of five of the Company’s patents. Fairchild has withdrawn its claim for infringement of one of the patents it asserted against the Company after the Company’s preliminary challenge. The parties streamlined their contentions in view of the Court's pretrial rulings, and following a trial in late May and early June 2015, a jury returned a verdict finding that Fairchild infringed one of the Company's patents, that Fairchild has induced and contributed to others' infringement of the Company's patent, and that the Company induced infringement of a Fairchild patent that was previously
71
found infringed in the 2012 trial described above, with a damages award of $2.4 million in favor of Fairchild. However, in parallel proceedings the Patent Office has rejected all of the asserted claims of the one Fairchild patent found infringed, determinations that Fairchild is challenging on appeal, and the Court rejected Fairchild’s earlier request for an injunction based on those same claims. Both parties have filed post-trial motions and challenges to various portions of the jury verdicts, and the Court is expected to address the first wave of post-trial motions over the coming months. The Company believes it has valid defenses against the $2.4 million award in favor of Fairchild, and therefore has not recorded a loss in its financial statements at this time.
On October 21, 2015, the Company filed a complaint for patent infringement against Fairchild Semiconductor Corporation, Fairchild Semiconductor International, Inc., and wholly-owned subsidiary Fairchild (Taiwan) Corporation (referred to collectively as “Fairchild”) to address Fairchild’s continued infringement of two patents Fairchild was previously found to infringe in the three District Court cases the Company brought against Fairchild discussed above. In each of the three prior cases, Fairchild was found to infringe one of the patents at issue in the latest complaint, and Fairchild’s challenges to the validity of the patents were rejected during the course of the prior lawsuits as well. Fairchild has not yet answered the complaint, and no trial date has been scheduled, but further proceedings are expected over the course of the coming months.
The Company is unable to predict the outcome of legal proceedings with certainty, and there can be no assurance that Power Integrations will prevail in the above-mentioned unsettled litigations. These litigations, whether or not determined in Power Integrations' favor or settled, will be costly and will divert the efforts and attention of the Company's management and technical personnel from normal business operations, potentially causing a material adverse effect on the business, financial condition and operating results. Currently, the Company is not able to estimate a loss or a range of loss for the ongoing litigation disclosed above, however adverse determinations in litigation could result in monetary losses, the loss of proprietary rights, subject the Company to significant liabilities, require Power Integrations to seek licenses from third parties or prevent the Company from licensing the technology, any of which could have a material adverse effect on the Company's business, financial condition and operating results.
11. ACQUISITIONS:
Cambridge Semiconductor Limited
In December 2014, the Company entered into a loan agreement with Cambridge Semiconductor Limited (CamSemi), a UK company, in which $6.6 million was outstanding as of December 31, 2014. The estimated fair value of the loan, which was a level 3 fair value measurement approximated the carrying value of $6.6 million, as the loan was outstanding for less than a month and the interest rate approximated a market rate for such a loan. The loan was in anticipation of a definitive agreement the Company entered into to acquire CamSemi on January 2, 2015.
On January 2, 2015, the Company acquired 100% of the shares outstanding of CamSemi for total consideration of approximately $23.3 million, of which $16.7 million was paid in cash and $6.6 million was applied against the outstanding loan owed to the Company. The acquisition-related costs for the purchase of CamSemi totaled $1.0 million, with $0.8 million recognized in 2014 and $0.2 million recognized in 2015.
CamSemi was acquired to accelerate the Company's product development efforts for the low-power market. The acquisition also broadens the Company's technology and product portfolio for low-power applications, particularly in the mobility and LED lighting markets. The purchase price allocated to goodwill in the acquisition (as noted in the purchase price allocation below) is related largely to synergies and economies of scale expected from combining the operations of CamSemi with those of the Company.
72
The following table summarizes the purchase price and estimated fair values of the assets acquired and the liabilities assumed as of January 2, 2015, the completion of the acquisition of CamSemi:
(in thousands) | Total Amount | |||
Assets Acquired | ||||
Cash | $ | 1,134 | ||
Accounts receivable | 1,891 | |||
Inventories | 1,409 | |||
Prepaid expenses and other current assets | 408 | |||
Tax receivable | 1,093 | |||
Intangible assets: | ||||
Developed technology | 6,600 | |||
Customer relationships | 2,420 | |||
Goodwill | 11,250 | |||
Total assets acquired | 26,205 | |||
Liabilities Assumed | ||||
Current liabilities | 1,832 | |||
Taxes payable | 1,090 | |||
Total liabilities assumed | 2,922 | |||
Total purchase price | $ | 23,283 | ||
The following table represents details of the purchased intangible assets:
Fair Value Amount (in thousands) | Estimated Useful Life (in years) | ||||||
Developed technology | $ | 6,600 | 3 | - | 7 | ||
Customer relationships | 2,420 | 5 | |||||
Total acquired CamSemi intangibles | $ | 9,020 | |||||
The fair value of the identifiable intangible assets: developed technology and customer relationships were determined based on the following approach.
Developed Technology. The income approach was used to value the acquired developed technology. Revenue attributable to the Company’s technology was estimated based on expected evolution of the technology over time. Expenses were assumed to reflect the costs necessary to support the developed technology. The present value was capitalized as developed technology as of the acquisition date and is being amortized using a straight-line method to cost of revenues over the estimated life of 3 - 7 years.
Customer Relationships. An intangible customer relationship asset was recognized to the extent that the Company was expected to benefit from future revenues reasonably anticipated given the historical customer relationships and operating practices of CamSemi. In order to determine the fair value of the customer relationships, the Company’s analysis assumed that the Company would immediately benefit from the economics generated by CamSemi’s existing customer relationships. This amount was reduced by the potential impact given no past customer relationships and the assumption that the Company could reacquire the customer relationships and ramp up to a similar level of revenue within two years. The fair value of customer relationships was capitalized as of the acquisition date and is being amortized on a straight line basis to sales and marketing expenses over the estimated life of 5 years.
Pro forma results of operations for this acquisition have not been presented because it is not material to the Company’s consolidated financial statements.
Corporate Headquarters Building
In August 2015, the Company purchased a building adjacent to its corporate headquarters in San Jose, California to support the continued growth of the business. The purchase has been accounted for using the acquisition method of accounting
73
in accordance with ASC 805, Business Combinations, as the building had existing rental income resulting from in-place lease agreements with third-party tenants. The aggregate purchase price of $10.4 million, funded with cash on hand, was allocated as follows: $3.5 million for land, $6.3 million for building and improvements, $0.7 million for in-place leases and $(0.1) million for liabilities assumed. The building and improvements are being depreciated on a straight-line basis over an estimated useful life of up to 30 years. Additionally, as a result of the purchase, the Company acquired existing third-party leases that were valued as in-place lease intangible assets and are being amortized over the weighted average estimated life of 2 years. The valuation of the acquired in-place leases were estimated by the Company based on the amount of avoided cash outflows necessary to originate such leases. Acquisition-related costs in connection with the building purchase were included in other income, net in the consolidated statements of income and were not material for the periods presented.
Rental income from third-party leases, and the proportionate share of building expenses for those leases, are included in other income, net in the consolidated statements of income from the date of acquisition. These amounts were not material for the periods presented.
12. RETIREMENT PLANS:
In connection with the Company's acquisition of Concept in May 2012, the Company sponsors a defined benefit pension plan (Pension Plan) in accordance with the legal requirements of Switzerland. The plan assets, which provide benefits in the event of an employee’s retirement, death or disability, are held in legally autonomous trustee-administered funds that are subject to Swiss law. Benefits are based on the employee’s age, years of service and salary, and the plan is financed by contributions by both the employee and the Company.
The net periodic benefit cost of the Pension Plan was not material to the Company's financial statements during the years ended December 31, 2015, 2014 and 2013. At December 31, 2015, the projected benefit obligation was $9.0 million, the plan assets were $6.0 million and the net pension liability was $3.0 million. As of December 31, 2014, the projected benefit obligation was $8.1 million, the plan assets were $5.8 million, and the net pension liability was $2.3 million. The Company has recorded the unfunded amount as a liability in its Consolidated Balance Sheet at December 31, 2015 and 2014, under the other liabilities caption. The Company expects to make contributions to the Pension Plan of approximately $0.4 million during 2016. The unrealized actuarial loss on pension benefits, net of tax at December 31, 2015, 2014 and 2013 was $1.6 million, $1.2 million and $0.8 million, respectively. These amounts were reflected in Note 2 above under the caption accumulated other comprehensive income.
In accordance with the Compensation-Retirement Benefits Topic of ASC 715-20, Defined Benefits Plan, the Company recognizes the over-funded or under-funded status of its defined post-retirement plan as an asset or liability in its statement of financial position. The company measured the plan assets and benefit obligations as of the date of the fiscal year-end.
13. BANK LINE OF CREDIT:
On July 5, 2012, the Company entered into a Credit Agreement with two banks. The Credit Agreement provides the Company with a $100.0 million revolving line of credit to use for general corporate purposes with a $20.0 million sublimit for the issuance of standby and trade letters of credit. The Credit Agreement was amended on April 1, 2014, to extend the Credit Agreement termination date from July 5, 2015, to April 1, 2017, with all other terms of the Credit Agreement remaining the same. The Company’s ability to borrow under the revolving line of credit is conditioned upon the Company’s compliance with specified covenants, including reporting and financial covenants, primarily a minimum cash requirement and a debt to earnings ratio, with which the Company is currently in compliance. All advances under the revolving line of credit will become due on April 1, 2017, or earlier in the event of a default. As of December 31, 2015, the Company had no amount outstanding under the Credit Agreement.

Schedule II
Valuation and Qualifying Accounts
The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of customers to make required payments. This allowance is established using estimates formulated by the Company’s management based upon factors such as the composition of the accounts receivable aging, historical bad debt, changes in payments patterns, customer creditworthiness, and current economic trends. The Company maintains an allowance for the distributors’ ship and debit credits relating to the sell-through of the Company’s products. This reserve is established using the Company’s historical ship and debit amounts and levels of inventory in the distributor channels.
