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 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, computing and networking equipment, appliances, electronic utility meters, battery-powered tools, industrial controls, and “home-automation,” or “internet of things” applications such as networked thermostats, power strips and security devices. We also supply high-voltage LED drivers, which are AC-DC ICs specifically designed for lighting applications that utilize light-emitting diodes, and motor-driver ICs addressing brushless DC (BLDC) motors used in refrigerators, HVAC systems, ceiling fans and other consumer-appliance and light commercial applications.
We also offer high-voltage gate drivers-either standalone ICs or circuit boards containing ICs, electrical isolation components and other circuitry-used to operate high-voltage switches such as insulated-gate bipolar transistors (IGBTs) and silicon-carbide (SiC) MOSFETs. These combinations of switches and drivers are used for power conversion in high-power applications (i.e., power levels ranging from a few kilowatts up to gigawatts) such as industrial motors, solar- and wind-power systems, electric vehicles (EVs) 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 reduce the energy consumption of power converters during normal use and in “standby” operation, when the end product is not in use. In addition to the environmental benefits of reduced energy usage, our energy-saving technologies provide a number of benefits to our customers; these include helping them meet the increasingly stringent efficiency standards now in effect for many electronic products, and enabling the elimination of bulky heatsinks used to dissipate the heat produced by wasted electricity.
While the size of our addressable market fluctuates with changes in macroeconomic and industry conditions, the market has generally exhibited a modest growth rate over time as growth in the unit volume of power converters has been offset to a large degree by reductions in the average selling price of components in this market. Therefore, the growth of our business depends largely on increasing our penetration of the markets that we serve and on further expanding our addressable market. Our growth strategy includes the following elements:
●Increase our penetration of the markets we serve. We currently address AC-DC applications with power outputs up to approximately 500 watts, gate-driver applications ranging from a few kilowatts up to gigawatts, and motor-drive applications up to approximately 400 watts. Through our research and development efforts, we seek to introduce more advanced products for these markets offering higher levels of integration and performance compared to earlier products. We also continue to expand our sales and application-engineering staff and our network of distributors, as well as our offerings of technical documentation and design-support tools and services to help customers use our products. These tools and services include our PI Expert™ design software, which we offer free of charge, and our transformer-sample service.
Our market-penetration strategy also includes capitalizing on the importance of energy efficiency and renewable energy in the power conversion market. For example, our EcoSmart™ technology drastically reduces the amount of energy consumed by electronic products when they are not in use, helping our customers comply with regulations that seek to curb this so-called “standby” energy consumption. Also, our gate-driver products are critical components in energy-efficient DC motor drives, high-voltage DC transmission systems, solar and wind energy systems and electric transportation applications.
●Increase the size of our addressable market. Prior to 2010 our addressable market consisted of AC-DC applications with up to about 50 watts of output, a served available market (SAM) opportunity of approximately $1.5 billion. Since that time we have expanded our SAM to more than $4 billion through a variety of means. These include the introduction of products that enable us to address higher-power AC-DC applications (such as our Hiper™ product families), the introduction of LED-driver products, and our entry into the gate-driver market through the acquisition of CT-Concept Technologie AG in 2012. In 2016 we introduced the SCALE-iDriverTM family of ICs, broadening the range of gate-driver applications we can address, and in 2018 we introduced our BridgeSwitch™ motor-driver ICs, addressing BLDC motors, as described above. We have recently introduced a series of automotive-qualified versions of our products, including SCALE-iDriver, InnoSwitch™ and LinkSwitch™ ICs, targeting the EV market; we expect to introduce additional products targeting EVs in the future, and expect automotive applications to become a significant portion of our SAM over time.
Also contributing to our SAM expansion has been the emergence of new applications within the power ranges that our products can address. For example, applications such as “smart” utility meters, battery-powered lawn equipment and bicycles, and USB power receptacles (often installed alongside traditional AC wall outlets) can incorporate our products. The increased use of electronic intelligence and connectivity in consumer appliances has also enhanced our SAM.
Finally, we have enhanced our SAM through the development of new technologies that increase the value (and therefore the average selling prices) of our products. For example, our InnoSwitch™ ICs integrate circuitry from the secondary, or low-voltage, side of AC-DC power supplies, whereas earlier product families integrated circuitry only on the primary, or high-voltage side. In 2019 we began incorporating proprietary gallium-nitride (GaN) transistors in some our products, enabling a higher level of energy efficiency than ICs with traditional silicon transistors.
We intend to continue expanding our SAM in the years ahead through all of the means described above.
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 flat-panel TV, or it may be outside the device as in the case of a mobile-phone charger or an adapter for a cordless phone or cable modem.
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 availability 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 cost-effective alternatives to linear transformers in applications requiring more than a few 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 protection 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 gate drivers (or IGBT drivers), whose function is to ensure accurate, safe and reliable operation of the IGBT modules. Much like discrete power supplies, discrete gate 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, expanding the range of power-supply applications we can serve and enhancing our competitiveness in applications that we already addressed. In 2012 we expanded our addressable market to include high-voltage gate drivers.
Our ICs and gate 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 gate drivers enable designs with up to 70% fewer components than comparable discrete designs. This reduction in component count enhances reliability and efficiency, reduces size, 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 linear transformers, which are still used in some low-power applications.
●Reduced Time-to-Market, Enhanced Manufacturability
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. Also, our GaN transistor technology, introduced in 2019, offers substantially higher levels of active-mode efficiency compared to traditional silicon-based switches, while our BridgeSwitch motor-driver ICs enable efficiency of up to 98.5 percent, not only minimizing waste but also eliminating the need for heatsinks in many applications, which in turn reduces cost and weight.
●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 high-voltage gate drivers are used in applications with power levels as high as one gigawatt, while our motor-driver ICs address BLDC applications up to 300 watts. Within each of our product families, designers 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”); and 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 devices that are “always-on” but inactive may be causing as much as $19 billion in annual energy waste in the United States 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 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 have taken 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 (EISA); these federal standards were tightened in 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 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; further tightening of the standards is under consideration. The EISA legislation also required substantial improvements in the efficiency of lighting technologies beginning in 2012; as of 2014, traditional 100-, 75-, 60- and 40-watt bulbs are no longer permitted to be manufactured or sold in the United States. Plans to eliminate conventional incandescent bulbs have also been announced or enacted in other geographies such as Canada, Australia and Europe. In December 2019 the government of China published new efficiency standards for room air conditioners, which took effect on July 1, 2020.
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 also offer a range of products 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. We have also introduced products designed specifically for LED-lighting applications, known as LYTSwitch ICs, as well as a range of high-performance, high-voltage diodes known as Qspeed diodes.
In 2014 we introduced our InnoSwitch product family, the first power-supply ICs to combine primary, secondary and feedback circuits into a single package. These ICs employ 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.
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, and numerous other consumer and industrial applications, as well as LED lighting.
●High-voltage gate drivers
We offer a range of high-voltage gate-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 May 2016 we introduced the SCALE-iDriver family of standalone ICs, which enables us to address applications ranging from a few kilowatts up to about 100 kilowatts, whereas previously our sales of high-power products were primarily for applications above 100 kilowatts.
●Motor-driver products
The BridgeSwitch family of products, introduced in 2018, is a family of motor-driver ICs addressing BLDC motor applications up to approximately 400 watts. Such applications include refrigerator compressors, ceiling fans, air purifiers as well as pumps, fans and blowers used in consumer appliances such as dishwashers and laundry machines.

End Markets and Applications
Our net revenues consist primarily of sales of the products described above. When evaluating our net revenues, we categorize our sales into the following four major end-market groupings: communications, computer, consumer, and industrial.
The table below provides the approximate mix of our net sales by end market:
Our products are used in a vast range of power-conversion applications in the above-listed end-market categories. The following chart lists the most prominent applications for our products in each category.
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, 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%, 28% and 25% of our net product revenues in 2020, 2019 and 2018, respectively, while sales to distributors accounted for the remainder in each of the corresponding years. Most of our distributors are entitled to return privileges based on revenues 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 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.
Our top ten customers, including distributors that resell to OEMs and merchant power supply manufacturers, accounted for approximately 62%, 54% and 56% of net revenues in 2020, 2019 and 2018, respectively. In 2020, two distributors accounted for more than 10% of revenues. In 2019 and 2018, one of these distributors accounted for more than 10% of 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 and digital IC design, system architecture and packaging.
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. In 2020 we received 29 U.S. and 54 foreign patents. As of December 31, 2020, we held 450 U.S. patents and 360 foreign patents. Both U.S. and foreign patents have expiration dates ranging from 2021 to 2041. While our patent portfolio as a whole is important to the success of our business, we are not materially dependent upon any single patent. We also hold trademarks in the U.S. and various other geographies including Taiwan, Korea, Hong Kong, China, Europe, Japan, India, and Brazil.
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 used in the manufacture of our 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.
Manufacturing
We contract with three foundries for the manufacture of the vast majority of our silicon wafers: (1) 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 ICs are assembled, packaged and tested by independent subcontractors in China, Malaysia, Thailand and the Philippines; a small percentage of our ICs are tested at our headquarters facility in California. Our gate-driver boards are assembled and tested by independent subcontractors in Sri Lanka and Thailand; some of the boards are 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 certain aspects of the assembly process 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, which enables us to use our foundries’ older, lower-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 2028, December 2025 and December 2028, respectively. Under the terms of the Lapis and Epson agreements, each supplier 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 the supplier and us. In addition, Lapis and
Epson require us to supply them with a rolling six-month forecast on a monthly basis. Our agreements with Lapis and Epson each provide 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 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 ON Semiconductor, STMicroelectronics, Infineon, and Sanken Electric Company, as well as PWM-controller chips paired with discrete high-voltage bipolar transistors and MOSFETs; such controller chips 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 gate-driver products compete with alternatives from such companies as Avago, Infineon and Semikron, as well as driver circuits made up of discrete devices. Our motor-driver ICs compete with alternatives from such companies as ON Semiconductor, Infineon, STMicroelectronics and Sanken Electric Company.
Generally, our products enable customers to design power converters with total bill-of-materials 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 and conditions of sale, our liability is limited generally to either a credit equal to the purchase price or replacement of the defective part.
Human Capital
As of December 31, 2020, we employed 725 full-time personnel across 14 countries with 363, or 50% of the total, residing in North America, while 50% resided offshore comprising 259 in the Asia-Pacific region and 103 across Europe, Middle East and Africa. As of December 31, 2020, 5% of our worldwide employees were foreign nationals, defined as individuals requiring employment visas in the countries where they are employed. Women comprise more than 40% of our U.S. non-technical workforce. The ethnic makeup of our U.S. workforce is approximately as follows: 60% Asian; 29% white; 7% Hispanic or Latino; 4% other.

Approximately 97% of eligible U.S. employees participate in our 401(k) plan. These benefits, combined with our culture of innovation and sustainable growth, contribute to low employee turnover and an average tenure of nearly 10 years.
It is our policy to ensure equal employment opportunity for all applicants and employees without regard to prohibited considerations of race, color, religion, sex (including pregnancy, gender identity and sexual orientation), national origin, age, disability or genetic information, marital status or any other classification protected by applicable local, state or federal laws. Our employees are encouraged to engage with company leadership and raise concerns and questions in-person, via e-mail (anonymously if desired), or at our quarterly employee communications meeting with the CEO and senior management team. All employees receive training in the prevention of sexual harassment and abusive conduct in the workplace.

Item 1A.
Item 1A. Risk Factors.
The following are important factors that could cause actual results or events to differ materially from those contained in any forward-looking statements made by us or on our behalf. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we deem immaterial also may impair our business operations. If any of the following risks or such other risks actually occurs, our business could be harmed.
Risks Related to Ownership of Our Common 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:
●we face risks related to the Novel Coronavirus pandemic (COVID-19), which has disrupted and may again disrupt our operations, including our manufacturing, research and development, and sales and marketing activities, which could have a material adverse impact on our business, financial condition, operating results and cash flows;
●the volume and timing of delivery of orders placed by us with our wafer foundries and assembly subcontractors, and their ability to procure materials;
●the volume and timing of orders received from customers;
●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;
●reliance on international sales activities for a substantial portion of our net revenues;
●competitive pressures on selling prices;
●the ability of our products to penetrate additional markets;
●our ability to develop and bring to market new products and technologies on a timely basis;
●the lengthy timing of our sales cycle;
●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 ability to attract and retain qualified personnel;
●interruptions in our information technology systems;
●earthquakes, terrorists acts, pandemic or other disasters;
●fluctuations in exchange rates, particularly the exchange rate between the U.S. dollar and the Japanese yen, the Euro and the Swiss franc;
●the inability to adequately protect or enforce our intellectual property rights;
●expenses we are required to incur (or choose to incur) in connection with our intellectual property litigations;
●undetected defects and failures in meeting the exact specifications required by our products;
●risks associated with acquisitions and strategic investments;
●our ability to successfully integrate, or realize the expected benefits from, our acquisitions; and
●changes in tax rules and regulations, changes in interpretation of tax rules and regulations, or unfavorable assessments from tax audits may increase the amount of taxes we are required to pay;
●changes in environmental laws and regulations, including with respect to energy consumption and climate change;
●continued impact of changes in securities laws and regulations, including potential risks resulting from our evaluation of our internal controls over financial reporting; and
●uncertainties arising out of economic consequences of current and potential military actions or terrorist activities and associated political instability.
Risks Related to the Operation and Growth of Our Business
We face risks related to the Novel Coronavirus pandemic (COVID-19), which has disrupted and may again disrupt our operations, including our manufacturing, research and development, and sales and marketing activities, which could have a material adverse impact on our business, financial condition, operating results and cash flows. Our business as well as the business of our suppliers, customers and distributors have been and may continue to be adversely impacted by the world-wide response to COVID-19 such as public health measures, travel restrictions, business shutdowns, border closures, delivery and freight delays and other disruptions. These disruptions may adversely affect not only our sales and marketing activities, product development, manufacturing and product shipments which could negatively impact our ability to meet customer commitments but also our customers’ ability to manufacture their products, which could reduce their demand for our products. The effects of the pandemic have resulted in a significant economic downturn in local and global economies, as well as a significant downturn in financial markets, and the continuing pandemic could result in further significant economic downturns which may result in reduced end-customer demand and materially impact our revenues. All of these effects could have a material adverse effect on our customer relationships, operating results, cash flows, financial condition and have a negative impact on our stock price.
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 December 2025. 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.
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.
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 62%, 54% and 56% of our net revenues in each of the years ended December 31, 2020, 2019 and 2018, respectively. 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.
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%, 72% and 75% of net revenues in the years ended December 31, 2020, 2019 and 2018, respectively. 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 are 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.
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 98%, 97% and 96% of our net revenues for the year ended December 31, 2020, 2019 and 2018. 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:
●tariffs, protectionist measures and other trade barriers and restrictions;
●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;
●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.
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 2020 to 2039. 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.
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.
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.
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 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.
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.
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.
In the event of an earthquake, terrorist act, another pandemic 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.
Risks Related to Financial Performance or General Economic Conditions
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 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 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.
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 13, Legal Proceedings and Contingencies, in our Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. For example, 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.
Our products must meet exacting specifications, and undetected defects and failures may occur which may cause customers to return or stop buying our products and/or impose significant costs to us. 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 product warranty or liability claims and costs associated with customer support and product recalls, delays in or cancellations or rescheduling of orders or shipments and product returns or discounts. While we specifically exclude consequential damages in our standard terms and conditions, certain of our contracts may not exclude such liabilities. Our liability insurance which covers certain damages arising out of product defects may not cover all claims or be of a sufficient amount to fully protect against such claims. Costs or payments in connection with such claims could harm our operating results.
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. 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
●the risk of litigation or disputes with customers, suppliers, partners or stockholders of an acquisition target arising from a proposed or completed transaction;
●impairment of acquired intangible assets and goodwill as a result of changing business conditions, technological advancements or worse-than-expected performance, which would adversely affect our financial results; and
●unknown, underestimated and/or undisclosed commitments, liabilities or issues not discovered in our due diligence of such transactions.
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 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.
Risks Related to Laws and Regulations
Changes in tax rules and regulations, changes in interpretation of tax rules and regulations, or unfavorable assessments from tax audits 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 recently enacted or are 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.
Recently enacted U.S. tax legislation has significantly changed the taxation of U.S.-based multinational corporations, by, among other things, reducing the U.S. corporate income tax rate, adopting elements of a territorial tax system, assessing a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, and the creation of new taxes on certain foreign-sourced earnings. The legislation as initially enacted was unclear in some respects and has required interpretations and implementing regulations by the Internal Revenue Service, as well as state tax authorities, and the legislation has been subject to amendments and technical corrections. Further amendments and technical corrections may occur, any of which could lessen or increase certain adverse impacts of the legislation. A significant portion of our earnings are earned by our subsidiaries outside the U.S. Changes to the taxation of certain foreign earnings resulting from the newly enacted U.S. tax legislation, along with the state tax impact of these changes and potential future cash distributions, may have an adverse effect on our effective tax rate. Furthermore, changes to the taxation of undistributed foreign earnings could change our future intentions regarding reinvestment of such earnings. The foregoing items could have a material effect on our business, cash flow, results of operations or financial conditions.
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.
General Risk Factors
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.
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.
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.

Our common stock trades on the Nasdaq Global Select Market under the symbol “POWI”.
As of February 2, 2021, there were approximately 43 stockholders of record. Because brokers and other institutions hold many of our shares on behalf of stockholders, we are unable to estimate the total number of stockholders represented by these record holders.
Issuer Purchases of Equity Securities
Over the years our board of directors has authorized the use of funds to repurchase shares of our common stock, including $80.0 million in October 2018, with repurchases to be executed according to pre-defined price/volume guidelines. We did not repurchase any shares of our common stock in the fourth quarter of 2020. As of December 31, 2020, we had $41.3 million available for future stock repurchases in our repurchase program, which has no expiration date. 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 and business conditions as well as other factors.

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 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, computing and networking equipment, appliances, electronic utility meters, battery-powered tools, industrial controls, and “home-automation,” or “internet of things” applications such as networked thermostats, power strips and security devices. We also supply high-voltage LED drivers, which are AC-DC ICs specifically designed for lighting applications that utilize light-emitting diodes, and motor-driver ICs addressing brushless DC (BLDC) motors used in refrigerators, HVAC systems, ceiling fans and other consumer-appliance and light commercial applications.
We also offer high-voltage gate drivers-either standalone ICs or circuit boards containing ICs, electrical isolation components and other circuitry-used to operate high-voltage switches such as insulated-gate bipolar transistors (IGBTs) and silicon-carbide (SiC) MOSFETs. These combinations of switches and drivers are used for power conversion in high-power applications (i.e., power levels ranging from a few kilowatts up to gigawatts) such as industrial motors, solar- and wind-power systems, electric vehicles (EVs) and high-voltage DC transmission systems.
Our net revenues were $488.3 million, $420.7 million and $416.0 million in 2020, 2019 and 2018, respectively. In 2020, revenues increased by $67.6 million due to growth across all end markets reflecting increased adoption of higher-power chargers for mobile phones and tablets, increased sales for desktop computers and monitors, as well as a broad range of industrial and consumer-appliance applications. In 2019, revenues increased by $4.7 million due to growth in sales into the communications end-market, reflecting increased adoption of faster, higher-power chargers for mobile phones; this trend has resulted in both unit growth and higher average selling prices for our products in this market. Growth in revenues from the communications end-market was largely offset by lower sales into the consumer and industrial markets, primarily reflecting macroeconomic, cyclical and trade-related factors that have affected the broader semiconductor industry.
Our top ten customers, including distributors that resell to OEMs and merchant power supply manufacturers, accounted for approximately 62%, 54% and 56% of net revenues in 2020, 2019 and 2018, respectively. In 2020, two customers, distributors of our products, accounted for approximately 19% and 11% of net revenues. In 2019 and 2018, one of these customers accounted for approximately 11% and 14% of net revenues. International sales represented approximately 98%, 97% and 96% of net revenues in 2020, 2019 and 2018, respectively.
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 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.
Our gross profit, defined as net revenues less cost of revenues, was $243.6 million or 50% of net revenues in 2020, compared to $213.4 million or 51% of net revenues in 2019, and $214.8 million or 52% of net revenues in 2018. Our gross margin decreased in 2020 due primarily to an unfavorable change in end-market mix with a greater amount of revenues coming from lower-margin end markets. Our gross margin decreased in 2019 primarily due to increased wafer substrate costs.
Total operating expenses in 2020 were $173.1 million, compared to a net gain of $3.6 million in 2019 stemming from the $169.0 million gain on settlement of our litigation with ON Semiconductor. In 2018, total operating expenses were $159.1 million. Apart from the effects of the 2019 legal settlement, the increase in operating expenses in 2020 was due primarily to higher stock-based compensation expense related mainly to performance-based awards, along with higher salary and related expenses from annual merit increases and the expansion of our workforce. These increases were partially offset by lower legal expenses following the conclusion of our litigation with ON Semiconductor as well as lower travel expenses, trade event and promotional activities due to COVID-19 pandemic-related restrictions.
COVID-19 Pandemic
The COVID-19 pandemic has disrupted everyday life and markets worldwide, and governments around the world have imposed restrictions aimed at controlling the spread of the virus, including shelter-in-place orders, travel restrictions, business shutdowns and border closures. Beginning March 16, 2020 our San Jose headquarters location was subject to a shelter-in-place order, under which most of our employees were required to work from home; other locations around the world have also been subject to such restrictions. We will begin a phased reopening of our San Jose headquarters when these restrictions are lifted. Some of our employees in other locations around the world have returned to the office under a phased reopening plan. We have implemented a variety of measures to protect the health and safety of our employees, including the provision of masks, gloves and sanitizers, social-distancing rules, and regular deep cleaning of our facilities.
While we have been able to conduct our day-to-day operations effectively in spite of the restrictions caused by the pandemic, the pandemic has caused disruptions in our supply chain. While the supply of wafers from our foundry partners has not been interrupted, government-mandated closures in China, Malaysia, Sri Lanka and the Philippines in the early stages of the pandemic caused temporary shutdowns at our assembly and test sub-contractors in those countries. All of the affected sub-contractors have now resumed operations. While these disruptions resulted in delayed shipments to some customers, our results were not materially affected due to a variety of mitigation measures including higher-than-normal inventories of wafers and finished goods, safety stocks of certain key inputs, and multiple sources for components for most of our products.
Despite the economic downturn stemming from the pandemic, demand for goods incorporating our products is strong. While the future trajectory of demand is highly uncertain, we believe our business is fundamentally sound with strong, long-term growth prospects. We have not reduced headcount and intend to continue investing in research and development and other functions necessary to support our future growth. We also intend to continue our cash dividend and stock repurchase programs; however, if the economy deteriorates more than we expect or our business outlook changes, our board of directors may choose to suspend or alter these programs at its discretion. For additional discussion regarding COVID-19 business risks refer to Part I, Item 1A “Risk Factors” in this Annual Report on Form 10-K.
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; and
●income taxes.
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 and Recent Accounting Pronouncements, in our Notes to Consolidated Financial Statements in this Annual Report on Form 10-K.
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 2020. We apply the provisions of Accounting Standards Codification (ASC) 606-10, Revenue from Contracts with Customers, and all related appropriate guidance. We recognize revenue under the core principle to depict the transfer of control to our customers in an amount reflecting the consideration we expect to be entitled. In order to achieve that core principle, we apply the following five-step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied.
Product revenues consist of sales to original equipment manufacturers, or OEMs, merchant power supply manufacturers and distributors. We consider customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer. In situations where sales are to a distributor, we have concluded that our contracts are with the distributor as we hold contracts bearing enforceable rights and obligations with only the distributor. As part of our consideration of the contract, we evaluate certain factors including the customer’s ability to pay (or credit risk). For each contract, we consider the promise to transfer products, each of which is distinct, to be the identified performance obligations. In determining the transaction price we evaluate whether the price is subject to refund or adjustment to determine the net consideration to which we expect to be entitled. As our standard payment terms are less than one year, we elected the practical expedient under ASC 606-10-32-18 to not assess whether a contract has a significant financing component. We allocate the transaction price to each distinct product based on their relative standalone selling price. We consider the product price as specified on the purchase order the standalone selling price as it is an observable input which depicts the price as if sold to a similar customer in similar circumstances. We recognize revenue when control of the product is transferred to the customer (i.e., when our performance obligation is satisfied), which typically occurs at shipment. Further, in determining whether control has transferred, we consider if there is a present right to payment and legal title, along with risks and rewards of ownership having transferred to the customer.
Frequently, we receive orders for products to be delivered over multiple dates that may extend across several reporting periods. We invoice for each delivery upon shipment and recognize revenue for each distinct product delivered, assuming transfer of control has occurred. As scheduled delivery dates are within one year, under the optional exemption provided by ASC 606-10-50-14 revenues allocated to future shipments of partially completed contracts are not disclosed. We have also elected the practical expedient under ASC 340-40-25-4 to expense commissions when incurred as the amortization period of the commission asset we would have otherwise recognized is less than one year.
Sales to international customers that are shipped from our facility outside of the United States are pursuant to EX Works, or EXW, shipping terms, meaning that control of the product transfers to the customer upon shipment from our foreign warehouse. Sales to international customers that we ship from our facility in California are pursuant to Delivered at Frontier, or DAF, shipping terms. As such, control of the product passes to the customer when the shipment reaches the destination country and we recognize revenue upon the arrival of the product in that country. Shipments to customers in the Americas are pursuant to Free on Board, or FOB, point of origin shipping terms meaning that we pass control to the customer upon shipment.
Sales to most distributors are made under terms allowing certain price adjustments and limited rights of return (known as “stock rotation”) of our products held in their inventory or upon sale to their end customers. We recognize revenue from sales to distributors upon the transfer of control to the distributor. 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, we issue a credit memo to the distributor for the ship and debit claim. In determining the transaction price, we consider ship and debit price adjustments to be variable consideration. Such price adjustments are estimated using the expected value method based on an analysis of actual ship and debit claims, at the distributor and product level, over a period of time considered adequate
to account for current pricing and business trends. Historically, actual price adjustments for ship and debit claims relative to those estimated and included when determining the transaction price have not materially differed. To the extent future ship and debit claims significantly exceed amounts estimated, there could be a material impact on our revenues and results of operations. Stock rotation rights grant the distributor the ability to return certain specified amounts of inventory. Stock rotation adjustments are an additional form of variable consideration and are also estimated using the expected value method based on historical return rates. Historically, these distributor stock rotation adjustments have not been material.
Sales to certain distributors are made under terms that do not include rights of return or price concessions after the product is shipped to the distributor. Accordingly, upon application of steps one through five above, product revenue is recognized upon shipment and transfer of control.
We generally provide an assurance warranty that our products will substantially conform to the published specifications for twelve months from the date of shipment. Our 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. As such, we do not record a specific warranty reserve or consider activities related to such warranty, if any, to be a separate performance obligation.
Income taxes
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 deferred tax assets to the amount that we estimate will more likely than not be realized based on available evidence and management’s judgment. 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, 2020, we continue to maintain a valuation allowance on our California, New Jersey and Canada deferred tax assets as we believe that it is not more likely than not that the deferred tax assets will be fully realized.
Results of Operations
The following table sets forth statement of income data as a percentage of net revenues for the periods indicated:
Comparison of Years Ended December 31, 2020, 2019 and 2018
Net revenues. Net revenues consist of revenues from product sales, which are calculated net of returns and allowances. In 2020 revenues increased by $67.6 million compared to 2019 due to growth across all end markets reflecting increased adoption of higher-power chargers for mobile phones and tablets, increased sales for desktop computers and monitors, as well as a broad range of consumer appliance and industrial applications. In 2019 revenues increased by $4.7 million compared to 2018 as growth in the communications end-market more than offset a broad-based decline in demand across the consumer and industrial end markets.
Our approximate net revenue mix by end-markets served in 2020, 2019 and 2018 is as follows:
Sales to customers outside of the United States were $477.3 million in 2020, compared to $410.0 million in 2019 and $400.6 million in 2018, representing approximately 98%, 97% and 96% of net revenues in 2020, 2019 and 2018, respectively. 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 81% of our net revenues in 2020, and 77% of our net revenues in each of 2019 and 2018. We expect international sales to continue to account for a large portion of our net revenues for the foreseeable future.
Sales to distributors accounted for 75%, 72% and 75% of our net revenues in 2020, 2019 and 2018, respectively, with direct sales to OEMs and merchant power supply manufacturers accounting for the remainder in each of the corresponding years.
The following customers represented 10% or more of our net revenues for the respective 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 following table compares gross profit and gross margin for the years ended December 31, 2020, 2019 and 2018:
Our gross margin decreased in 2020 as compared to 2019 primarily due to an unfavorable change in end-market mix with a greater amount of revenues coming from lower-margin end markets. Our gross margin decreased in 2019 as compared to 2018 primarily due to increased wafer substrate costs.
Research and development expenses. Research and development (R&D) expenses consist primarily of employee-related expenses including salaries and stock-based compensation, as well as expensed material and facility costs associated with the development of new processes and products. We also record R&D expenses for prototype wafers related to new products until the products are released to production. The following table compares R&D expenses for the years ended December 31, 2020, 2019 and 2018:
R&D expenses increased in 2020 compared to 2019 due to higher salary and related expenses driven by expansion of headcount and annual merit increases, increased equipment-related expenses in support of product development as well as higher stock-based compensation expense primarily related to performance-based awards. R&D expenses increased in 2019 compared to 2018 due to higher salary and related expenses driven by increased headcount as well as increased equipment-related expenses.
Sales and marketing expenses. Sales and marketing (S&M) expenses consist primarily of employee-related expenses, including salaries and stock-based compensation, and commissions to sales representatives, as well as amortization of acquired intangible assets and facilities expenses, including expenses associated with our regional sales and support offices. The following table compares sales and marketing expenses for the years ended December 31, 2020, 2019 and 2018:
S&M expenses increased in 2020 compared to 2019 due to higher salary and related expenses from the expansion of headcount and higher stock-based compensation expense primarily related to performance-based awards. These factors were partially offset by lower travel expenses, trade event and promotional activities resulting from restrictions associated with the COVID-19 pandemic, as well as lower amortization of intangibles. S&M expenses increased in 2019 as compared to 2018 due primarily to expansion of our sales force, resulting in higher salary and related expenses, partially offset by lower amortization of intangibles.
General and administrative expenses. General and administrative (G&A) expenses consist primarily of employee-related expenses, including salaries and 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, 2020, 2019 and 2018:
G&A expenses decreased in 2020 due to lower patent-litigation expenses partially offset by higher stock-based compensation expense primarily related to performance-based awards. G&A expenses increased in 2019 as a result of increased expenses related to patent litigation and higher salary and related expenses due to expansion of headcount.
Litigation settlement. Litigation settlement in fiscal 2019 represents a $169.0 million gain net of direct legal fees due to a favorable legal settlement with ON Semiconductor Corporation, pursuant to which all outstanding legal and administrative disputes were dismissed, withdrawn, and/or terminated.
Other income. Other income 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 following table compares other income for the years ended December 31, 2020, 2019 and 2018:
Other income decreased in 2020 due primarily to lower interest income, reflecting lower yields earned on our cash and investments despite higher cash and investment balances. Other income increased in 2019 due primarily to an increase in interest income reflecting an increase in our cash and investments along with higher yields earned on those balances.
Provision (benefit) for income taxes. Provision (benefit) for income taxes represents federal, state and foreign taxes. The following table compares the provision (benefit) for income taxes for the years ended December 31, 2020, 2019 and 2018:
In 2020, 2019 and 2018, the effective tax rate was lower than the statutory U.S. federal income-tax rates of 21% due to the geographic distribution of our world-wide earnings in lower tax jurisdictions, the impact of federal research tax credits and the recognition of excess tax benefits related to share-based compensation. These benefits were partially offset by U.S. tax on foreign income, known as global intangible low-taxed income. Additionally, in 2018 the effective tax rate was favorably impacted by revisions to our provisional estimate for the enactment of the U.S. Tax Cuts and Jobs Act (Tax Act). The primary jurisdiction from which our foreign earnings are derived is the Cayman Islands, which is a non-taxing jurisdiction. Income earned in other foreign jurisdictions was not material. We have not been granted any incentivized tax rates and do not operate under any tax holidays in any jurisdiction. For additional details, refer to Note 11, Provision (Benefit) for Income Taxes, in our Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K.
Liquidity and Capital Resources
We had approximately $449.2 million in cash, cash equivalents and short-term marketable securities at December 31, 2020 compared to $411.1 million at December 31, 2019, and $228.6 million at December 31, 2018. As of December 31, 2020, 2019 and 2018, we had working capital, defined as current assets less current liabilities, of approximately $538.7 million, $490.9 million and $284.1 million, respectively.
We have a credit agreement with a bank (the "Credit Agreement") that provides us with a $75.0 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. Our ability to borrow under the revolving line of credit is conditioned upon our compliance with specified covenants, including reporting and financial covenants, primarily a minimum liquidity measure and a debt to earnings ratio, with which we are currently in compliance. The Credit Agreement terminates on April 30, 2022; 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, 2020, and 2019, we had no advances outstanding under the Credit Agreement.
Our operating activities generated cash of $125.6 million, $224.5 million, and $84.0 million in the years ended December 31, 2020, 2019 and 2018, respectively. We generate cash primarily from operating activities in the ordinary course of business. In addition, in 2019 our cash generated from operating activities was favorably impacted by the settlement of our patent litigation with ON Semiconductor Corporation.
Cash Provided by Operating Activities
In 2020, our net income was $71.2 million, which reflected non-cash charges of $30.9 million of stock-based compensation expenses, $23.7 million of depreciation and $4.4 million of intangibles amortization. Sources of cash also included a $9.1 million decrease in prepaid expenses and other assets, primarily driven by taxes refunded, a $5.7 million increase in accounts payable (excluding payables related to property and equipment) and a $4.1 million increase in taxes payable and accrued liabilities, in each case due to the timing of payments. These sources of cash were partially offset by an $11.3 million increase in accounts receivable due to increased shipments and the timing of collections, a $12.5 million increase in inventories, reflecting impact of a market slowdown during the first half of the year and higher inventory levels to support anticipated future demand.
In 2019, our net income was $193.5 million, which included a $169.0 million gain, net of direct legal fees, from a favorable litigation settlement, $23.3 million of stock-based compensation expenses, $19.2 million of depreciation and $5.2 million of intangibles amortization. Sources of cash also included a $10.6 million increase in taxes payable and accrued liabilities due primarily to increased taxes payable as result of favorable litigation settlement. These sources of cash were partially offset by a $13.3 million increase in accounts receivable due to increased shipments and the timing of collections, a $9.5 million increase in inventories in anticipation of future demand, and a $6.6 million decrease in accounts payable due to the timing of payments.
In 2018, our net income was $70.0 million, which included stock-based compensation expenses, depreciation and intangibles amortization of $21.6 million, $18.9 million, and $5.3 million, respectively. Sources of cash also included a $5.8 million decrease in accounts receivable due to decreased shipments and the timing of collections. These sources of cash were partially offset by a $23.8 million increase in inventories, partially reflecting lower-than-normal inventory levels at the beginning of the year, but also driven by lower-than-expected sales, particularly in the latter half of the year, and a $9.9 million decrease in taxes payable and accrued liabilities due primarily to a decrease in taxes payable related to the enactment of the Tax Act.
Cash Provided by (Used in) Investing Activities
Our investing activities in the year ended December 31, 2020 resulted in a $28.3 million net use of cash, consisting primarily of $41.7 million from purchases of marketable securities, net of sales and maturities, and $70.6 million for purchases of property and equipment, primarily machinery and equipment for use in the manufacture of our products and a building for our design center in Germany.
Our investing activities in the year ended December 31, 2019 resulted in a $162.0 million net use of cash, consisting primarily of $136.9 million from purchases of marketable securities, net of sales and maturities, and $24.1 million for purchases of property and equipment, primarily machinery and equipment for use in the manufacture of our products.
Our investing activities provided $69.1 million of cash in the year ended December 31, 2018, consisting primarily of $94.7 million from sales and maturities of marketable securities, net of purchases, partially offset by $24.7 million for purchases of property and equipment, primarily machinery and equipment for use in the manufacture of our products.
Cash Used in Financing Activities
Our financing activities in the year ended December 31, 2020, resulted in a net use of $17.2 million of cash. Financing activities consisted primarily of $25.1 million for the payment of dividends to stockholders and $2.6 million for the repurchase of our common stock, partially offset by proceeds of $10.5 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, 2019, resulted in a net use of $17.9 million of cash. Financing activities consisted primarily of $20.5 million for the payment of dividends to stockholders and $7.3 million for the repurchase of our common stock, partially offset by proceeds of $9.9 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, 2018, resulted in a net use of $112.6 million of cash. Financing activities consisted primarily of $103.2 million for the repurchase of our common stock and $18.8 million for the payment of dividends to stockholders, partially offset by proceeds of $9.4 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.
Dividends
In January 2018, our board of directors declared four quarterly cash dividends in the amount of $0.08 per share to be paid to stockholders of record at the end of each quarter in 2018. In January 2019, our board of directors declared four quarterly cash dividends of $0.085 per share to be paid to stockholders of record at the end of each quarter in 2019. In October 2019, our board of directors raised the cash dividends per share with the declaration of five cash dividends, consisting of (a) a dividend of $0.01 per share to be paid to stockholders of record at the end of the fourth quarter in 2019, that was in addition to the dividend of $0.085 per share to be paid to stockholders of record at the end of the fourth quarter in 2019 previously declared by the board in January 2019, and (b) a dividend of $0.095 per share to be paid to stockholders of record at the end of each quarter in 2020. In April 2020, our board of directors raised the cash dividends with the declaration of three cash dividends of $0.105 per share (in lieu of the $0.095 per share previously announced in October 2019) to be paid to stockholders of record at the end of each of the second, third and fourth quarter in 2020. In July 2020, our board of directors raised the cash dividends further with the declaration of two cash dividends of $0.11 per share (in lieu of the $0.105 per share announced in April 2020) to be paid to stockholders of record at the end of each of the third and fourth quarter in 2020. In January 2021, our board of directors raised the quarterly cash dividend by an additional $0.02 per share with the declaration of four cash dividends of $0.13 per share to be paid to stockholders of record at the end of each quarter in 2021. 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. The dividends per share presented above reflect the 2-for-1 stock split implemented as a stock dividend in August 2020.
Stock Repurchases
Over the years our board of directors has authorized the use of funds to repurchase shares of our common stock, including $80.0 million in October 2018 with repurchases to be executed according to pre-defined price/volume guidelines. In 2018, we purchased 3,144,000 shares for approximately $103.2 million. In 2019, we purchased 242,000 shares for approximately $7.3 million. In 2020, we purchased 63,000 shares for approximately $2.6 million. As of December 31, 2020, $41.3 million was available for future stock repurchases, which has no expiration date. 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 and business conditions as well as other factors.
As of December 31, 2020, we had a contractual obligation related to income tax, consisting primarily of unrecognized tax benefits of approximately $21.1 million. The tax obligation was classified as long-term income taxes payable or recorded as contra deferred tax assets in our consolidated balance sheet.
Other Information
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. The Tax Act signed into law on December 22, 2017 subjects U.S. companies to a one-time transition tax on total post-1986 earnings and profits of their foreign subsidiaries and generally allows companies to repatriate accumulated foreign earnings without incurring additional U.S. federal taxes beginning after December 31, 2017. Accordingly, as of December 31, 2020, our worldwide cash and marketable securities are available to fund capital allocation needs, including capital and internal investments, acquisitions, stock repurchases and/or dividends without incurring significant U.S. federal income taxes.
If our operating results deteriorate in future periods, either as a result of a decrease in customer demand or 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, 2020 and 2019, 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, 2020, we had the following contractual obligations:
________________________
(1)Operating lease obligations represent undiscounted non-cancelable remaining lease payments.
(2)Purchase obligations represent commitments to our suppliers and other parties for the purchases of goods and services, which primarily consist of wafer and other inventory purchases, assembly and other manufacturing services, and purchases of property and equipment.
In addition to our contractual obligations noted above we have a contractual obligation related to income tax as of December 31, 2020, which primarily comprises unrecognized tax benefits of approximately $21.1 million, and was classified as contra deferred tax assets or long-term income taxes payable in our consolidated balance sheet. As of
December 31, 2020 we also had approximately $4.5 million classified as long-term income taxes payable related to the estimated one-time transition tax from the enactment of the Tax Act which will be payable in five annual installments.

Item 7A.
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, 2020 and 2019, we held primarily cash equivalents and short-term investments with fixed interest rates. We do not hold any instruments for trading purposes.
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, 2020, or December 31, 2019, 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 5, Marketable Securities, in our Notes to Consolidated Financial Statements in this Annual Report on Form 10-K, for a tabular presentation of our available-for-sale investments and the expected maturity dates.
Foreign Currency Exchange Risk. As of December 31, 2020, our primary transactional currency was the U.S. dollar; in addition, we hold cash in Swiss francs and euros to fund the operation of our Swiss subsidiary. 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, 2020. This sensitivity analysis applies a change in the U.S. dollar value of 5% and 10%.
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, 2020, and December 31, 2019, 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 (Epson) and ROHM Lapis Semiconductor Co., Ltd. (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 eventually result in a corresponding change in our gross margin of approximately 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Stockholders and the Board of Directors of Power Integrations, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Power Integrations, Inc. and subsidiaries (the "Company") as of December 31, 2020 and 2019, 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, 2020, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with the accounting principles generally accepted in the United States of America.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 5, 2021 expressed an unqualified opinion on the Company's internal control over financial reporting.
Change in Accounting Principle
As discussed in Note 12 to the financial statements, effective January 1, 2019, the Company adopted Accounting Standards Update (ASU) 2016-02, Leases (Topic 842), using the optional transition method.

POWER INTEGRATIONS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. THE COMPANY:
Power Integrations, Inc. (“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 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, which convert the high-voltage AC from a wall outlet to the low-voltage DC required by most electronic devices. Power supplies incorporating the Company’s products are used with all manner of electronic products including mobile phones, computing and networking equipment, appliances, electronic utility meters, battery-powered tools, industrial controls, and “home-automation,” or “internet of things” applications such as networked thermostats, power strips and other building-automation and security devices. The Company also supplies high-voltage LED drivers, which are AC-DC ICs specifically designed for lighting applications that utilize light-emitting diodes. In 2018, the Company introduced a new category of power-conversion ICs: a family of motor-driver ICs addressing brushless DC (BLDC) motors used in refrigerators, HVAC systems, ceiling fans and other consumer-appliance and light commercial applications. The Company also offers high-voltage gate drivers-either standalone ICs or circuit boards containing ICs, electrical isolation components and other circuitry-used to operate high-voltage switches such as insulated-gate bipolar transistors (IGBTs) and silicon-carbide (SiC) MOSFETs. These combinations of switches and drivers are used for power conversion in high-power applications (i.e., power levels ranging from a few kilowatts up to gigawatts) such as industrial motors, solar- and wind-power systems, electric vehicles and high-voltage DC transmission systems.
2. SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS:
Significant Accounting Policies and Estimates
Segment Reporting
The Company is organized and operates as one reportable segment, the design, development, manufacture and marketing of integrated circuits and related components for use primarily in the high-voltage power conversion markets. The Company’s chief operating decision maker, the Chief Executive Officer, reviews financial information presented on a consolidated basis for purposes of making operating decisions and assessing financial performance.
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. Generally Accepted Accounting Principles (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.
Revenue Recognition
The Company applies the provisions of Accounting Standards Codification (ASC) 606-10, Revenue from Contracts with Customers, and all related appropriate guidance. The Company recognizes revenue under the core principle to depict the transfer of control to the Company’s customers in an amount reflecting the consideration the Company expects to be entitled. In order to achieve that core principle, the Company applies the following five-step approach: (1) identify
the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied.
Product revenues consist of sales to original equipment manufacturers, or OEMs, merchant power supply manufacturers and distributors. The Company considers customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer. In situations where sales are to a distributor, the Company has concluded that its contracts are with the distributor as the Company holds a contract bearing enforceable rights and obligations only with the distributor. As part of its consideration of the contract, the Company evaluates certain factors including the customer’s ability to pay (or credit risk). For each contract, the Company considers the promise to transfer products, each of which is distinct, to be the identified performance obligations. In determining the transaction price the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. As the Company’s standard payment terms are less than one year, the Company has elected the practical expedient under ASC 606-10-32-18 to not assess whether a contract has a significant financing component. The Company allocates the transaction price to each distinct product based on their relative standalone selling price. The product price as specified on the purchase order is considered the standalone selling price as it is an observable input which depicts the price as if sold to a similar customer in similar circumstances. Revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied), which typically occurs at shipment. Further, in determining whether control has transferred, the Company considers if there is a present right to payment and legal title, along with risks and rewards of ownership having transferred to the customer.
Frequently, the Company receives orders for products to be delivered over multiple dates that may extend across several reporting periods. The Company invoices for each delivery upon shipment and recognizes revenues for each distinct product delivered, assuming transfer of control has occurred. As scheduled delivery dates are within one year, under the optional exemption provided by ASC 606-10-50-14 revenues allocated to future shipments of partially completed contracts are not disclosed. The Company has also elected the practical expedient under ASC 340-40-25-4 to expense commissions when incurred as the amortization period of the commission asset the Company would have otherwise recognized is less than one year.
Sales to international customers that are shipped from the Company’s facility outside of the United States are pursuant to EX Works, or EXW, shipping terms, meaning that control of the product transfers to the customer upon shipment from the Company’s foreign warehouse. Sales to international customers that are shipped from the Company’s facility in California are pursuant to Delivered at Frontier, or DAF, shipping terms. As such, control of 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 customers in the Americas are pursuant to Free on Board, or FOB, point of origin shipping terms meaning that control is passed to the customer upon shipment.
Sales to most distributors are made under terms allowing certain price adjustments and limited rights of return (known as “stock rotation”) of the Company’s products held in their inventory or upon sale to their end customers. Revenue from sales to distributors is recognized upon the transfer of control to the distributor. 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 the Company to adjust the distributor’s cost from the standard price to the pre-approved lower price. After the Company verifies that the claim was pre-approved, a credit memo is issued to the distributor for the ship and debit claim. In determining the transaction price, the Company considers ship and debit price adjustments to be variable consideration. Such price adjustments are estimated using the expected value method based on an analysis of actual ship and debit claims, at the distributor and product level, over a period of time considered adequate to account for current pricing and business trends. Historically, actual price adjustments for ship and debit claims relative to those estimated and included when determining the transaction price have not materially differed. Stock rotation rights grant the distributor the ability to return certain specified amounts of inventory. Stock rotation adjustments are an additional form of variable consideration and are also estimated using the expected value method based on historical return rates. Historically, distributor stock rotation adjustments have not been material.
Sales to certain distributors are made under terms that do not include rights of return or price concessions after the product is shipped to the distributor. Accordingly, upon application of steps one through five above, product revenue is recognized upon shipment and transfer of control.
The Company generally provides an assurance warranty that its products will substantially conform to the published specifications for twelve 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. As such, the Company does not record a specific warranty reserve or consider activities related to such warranty, if any, to be a separate performance obligation.
Inventories
Inventories (which consist of costs associated with the purchases of wafers from domestic and offshore foundries and of packaged components from offshore assembly manufacturers, as well as internal labor and overhead associated with the testing of both wafers and packaged components) are stated at the lower of cost (first-in, first-out) or market. Provisions, when required, are made to reduce inventories to their estimated net realizable values.
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’ 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.
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 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.
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, 2020, and December 31, 2019, the Company’s marketable securities consisted primarily of commercial paper, corporate bonds, government securities and/or other high-quality commercial securities.
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. The Company provided for a contribution of approximately $1.8 million, $1.4 million and $1.3 million in 2020, 2019 and 2018, respectively.
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 loss, a component of stockholders’ equity, and are amortized as a component of net periodic cost over the remaining estimated service period of participants.
Foreign Currency Risk and Foreign Currency Translation
As of December 31, 2020, 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 remeasurement of non-functional currency balances are recorded in other income in the accompanying consolidated statements of income. The Company realized a foreign exchange transaction loss of $0.5 million, $0.3 million and $0.1 million in 2020, 2019, and 2018 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 and amounted to $1.2 million, $1.4 million and $1.2 million in 2020, 2019 and 2018, respectively.
Research and Development
Research and development costs are expensed as incurred.
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 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, 2020. 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.
Adoption of New Accounting Standards
In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326), which modifies the measurement of expected credit losses on certain financial instruments. In addition, for available-for-sale debt securities, the standard eliminates the concept of other-than-temporary impairment and requires the recognition of an allowance for credit losses rather than reductions in the amortized cost of the securities. The Company adopted the new standard in the first quarter of 2020, effective January 1, 2020, using the modified-retrospective approach. For available-for-sale debt securities, the Company has made a policy election to present separately accrued interest receivable within prepaid expenses and other current assets on the consolidated balance sheet. Upon adoption, there was no impact on the Company’s consolidated financial statements.
3. COMPONENTS OF THE COMPANY’S CONSOLIDATED BALANCE SHEETS:
Accounts Receivable
The Company maintains an allowance for estimated credit 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 losses, changes in payments patterns, customer creditworthiness, and current economic trends. Receivables determined to be uncollectible are written off and deducted from the allowance.
Inventories
Property and Equipment
Depreciation expense for property and equipment for fiscal years ended December 31, 2020, 2019 and 2018, was approximately $23.7 million, $19.2 million and $18.9 million, respectively, and was determined using the straight-line method over the following useful lives:
Total property and equipment (excluding accumulated depreciation) located in the United States at December 31, 2020, 2019 and 2018, was approximately $167.0 million, $160.7 million and $167.6 million, respectively. In 2020, 2019 and 2018 approximately 14%, 14% and 12%, respectively, of total property and equipment (excluding accumulated depreciation) was held in Thailand by one of the Company’s subcontractors. Also in 2020, approximately 14% of total property and equipment was held by one of the Company’s subcontractors in Malaysia. No other country held 10% or more of total property and equipment in the periods presented.
Accumulated Other Comprehensive Loss
Changes in accumulated other comprehensive loss for the three years ended December 31, 2020:
(1)This component of accumulated other comprehensive loss is included in the computation of net periodic pension cost for the years ended December 31, 2020, 2019 and 2018.
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 equivalents 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 commercial paper. 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 does not hold any instruments that would be classified within Level 3 of the fair-value hierarchy.
The fair value hierarchy of the Company’s cash equivalents and marketable securities at December 31, 2020, and 2019, 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, 2020, and 2019.
5. MARKETABLE SECURITIES:
Amortized cost and estimated fair market value of marketable securities classified as available-for-sale (excluding cash equivalents) at December 31, 2020, were as follows:
The Company did not have any investments due in twelve months or greater as of December 31, 2020. Accrued interest receivable was $0.8 million at December 31, 2020 and was recorded within prepaid expenses and other current assets on the condensed consolidated balance sheet.
Amortized cost and estimated fair market value of marketable securities classified as available-for-sale (excluding cash equivalents) at December 31, 2019, were as follows:
Accrued interest receivable was $1.3 million at December 31, 2019 and was recorded within prepaid expenses and other current assets on the condensed consolidated balance sheet.
As of December 31, 2020, the Company had no marketable securities classified as available-for-sale (excluding cash equivalents) in a continuous unrealized loss position for which an allowance for credit losses was not recorded. The following table summarizes marketable securities classified as available-for-sale (excluding cash equivalents) in a continuous unrealized loss position for which an allowance for credit losses was not recorded at December 31, 2019:
The weighted average interest rate of investments at December 31, 2020 and 2019, was approximately 0.89% and 2.17%, respectively. In the year ended December 31, 2020, no unrealized losses on marketable securities were recognized in income.
6. GOODWILL AND INTANGIBLE ASSETS:
The carrying amount of goodwill as of December 31, 2020 and 2019 was $91.8 million with no changes to goodwill in any of the respective fiscal years.
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.
The Company amortizes the cost of all intangible assets over the shorter of the estimated useful life or the term of the developed technology, customer relationships, technology licenses and in-place leases, which range from two to twelve years, with the exception of $1.3 million paid to acquire an internet domain name. 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 $4.4 million, $5.2 million and $5.3 million in the years ended December 31, 2020, 2019 and 2018, respectively. The Company does not believe there is any significant residual value associated with the following intangible assets:
The estimated future amortization expense related to definite-lived intangible assets at December 31, 2020, is as follows:
7. STOCK PLANS AND SHARE BASED COMPENSATION:
The share and per share information for all periods presented in this Form 10-K has been adjusted for the effect of the August 2020 stock split. Refer to Note 10, Earnings Per Share, in this Form 10-K for details.
Stock Plans
As of December 31, 2020, the Company had three 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. Pursuant to the 2007 Plan, the exercise price for incentive stock options and non-statutory stock 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. The 2007 Plan expired in September 2017 with no further grants to be made under this plan; however previous grants under this plan shall remain outstanding until they are exercised, vest, forfeited or expire.
2016 Incentive Award Plan
The 2016 Incentive Award Plan (2016 Plan) was adopted by the board of directors on March 17, 2016 and approved by the stockholders on May 13, 2016. The 2016 Plan provides for the grant of RSU awards, PSU awards and PRSU awards. No other forms of equity-based awards, including stock options and stock appreciation rights, may be granted under the 2016 Plan. As of December 31, 2020, 2.2 million awards have been issued and approximately 2.8 million shares of common stock remain available for future grant under the 2016 Plan.
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 7.0 million shares of common stock were reserved for issuance to employees under the Purchase Plan. As of December 31, 2020, of the shares reserved for issuance, 6.6 million shares had been purchased and 0.4 million shares were reserved for future issuance under the Purchase Plan.
Shares Reserved
As of December 31, 2020, the Company had approximately 3.4 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.
The following table summarizes the stock-based compensation expense recognized in accordance with ASC 718-10 for the years ended December 31, 2020, 2019 and 2018:
The following table summarizes total compensation expense related to unvested awards not yet recognized, net of expected forfeitures, and the weighted average period over which it is expected to be recognized as of December 31, 2020:
Stock-based compensation expense in the year ended December 31, 2020, was approximately $30.9 million (comprising approximately $18.7 million related to restricted stock units, $10.2 million related to performance-based awards and $2.0 million related to the Company’s Purchase Plan).
Stock-based compensation expense in the year ended December 31, 2019, was approximately $23.3 million (comprising approximately $17.5 million related to restricted stock units, $4.1 million related to performance-based awards and $1.7 million related to the Company’s Purchase Plan).
Stock-based compensation expense in the year ended December 31, 2018, was approximately $21.6 million comprising approximately $16.6 million related to restricted stock units, $3.4 million related to performance-based awards and $1.6 million related to the Company’s Purchase Plan).
The Company did not grant stock options in the years ended December 31, 2020, 2019 and 2018, and therefore no fair-value assumptions are reported.
The fair value of employees’ stock purchase rights under the Purchase Plan was estimated using the Black-Scholes model with the following weighted-average assumptions used during the three years ended December 31, 2020, 2019 and 2018:
A summary of stock options outstanding as of December 31, 2020, and activity during three years then ended, is presented below:
The total intrinsic value of options exercised during the year ended December 31, 2020, 2019 and 2018, was $9.1 million, $8.3 million and $7.5 million, respectively.
The following table summarizes the stock options outstanding at December 31, 2020:
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.
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 performance conditions are not achieved, no compensation cost is recognized and any previously recognized compensation is reversed.
A summary of PSU awards outstanding as of December 31, 2020, and activity during the three years then ended, is presented below:
The grant-date fair value of PSU awards released, which were fully vested, in the years ended December 31, 2020, 2019 and 2018 was approximately $4.2 million, $1.6 million and $5.1 million, respectively.
PRSU Awards (Long-term Performance Based)
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. 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. The performance goals for PRSUs granted in fiscal 2020, 2019 and 2018 were based on the Company’s annual revenue growth over the respective three-year performance period.
Expense associated with these awards, net of estimated forfeitures, is recorded throughout the year based on an assessment of the expected achievement of the performance targets. 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, 2020, and activity during the three years then ended, is presented below:
In January 2020 it was determined that no shares subject to the PRSUs granted in 2017 vested in aggregate; thus no shares were released to the Company’s executives in 2020. The grant-date fair value of PRSU awards released, which were fully vested, in the years ended December 31, 2019 and 2018 was approximately $3.0 million and $2.0 million, respectively.
RSU Awards
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.
A summary of RSU awards outstanding as of December 31, 2020, and activity during the three years then ended, is presented below:
The grant-date fair value of RSUs vested in the years ended December 31, 2020, 2019 and 2018, was approximately $18.1 million, $16.9 million and $15.9 million, respectively.
8. SIGNIFICANT CUSTOMERS AND GEOGRAPHIC NET REVENUES:
Customer Concentration
The Company’s top ten customers accounted for approximately 62%, 54% and 56% of revenues in 2020, 2019 and 2018, respectively. A significant portion of these revenues are attributable to sales of the Company’s products to distributors of electronic components. These distributors sell the Company’s products to a broad, diverse range of end users, including OEMs and merchant power supply manufacturers. Sales to distributors in 2020, 2019 and 2018 were $367.7 million, $304.6 million and $313.9 million, respectively. Direct sales to OEMs and power-supply manufacturers accounted for the remainder.
The following customers represented 10% or more of the Company’s net revenues for the respective years:
________________________
*Total customer revenue was less than 10% of net revenues.
No other customers accounted for 10% or more of the Company’s net revenues in the periods presented.
Concentration of Credit Risk
Financial instruments that potentially subject the Company to concentrations of credit risk consisted principally of cash investments and trade receivables. The Company does not have any off-balance-sheet credit exposure related to its customers. As of December 31, 2020 and December 31, 2019, 90% and 63% of accounts receivable were concentrated with the Company’s top ten customers, respectively.
The following customers represented 10% or more of accounts receivable:
________________________
*Total customer accounts receivable was less than 10% of net accounts receivables.
No other customers accounted for 10% or more of the Company’s accounts receivable in the periods presented.
Geographic Net Revenues
The Company markets its products globally through its sales personnel and a worldwide network of independent sales representatives and distributors. Geographic net revenues based on “bill to” customer locations were as follows:
9. COMMON STOCK REPURCHASES AND CASH DIVIDENDS:
Common Stock Repurchases
Over the years the Company’s board of directors has authorized the use of funds to repurchase shares of the Company’s common stock, including $110.0 million in 2018, with repurchases to be executed according to pre-defined price/volume guidelines. In 2018, 2019 and 2020 the Company purchased approximately 3,144,000, 242,000 and 63,000 shares, respectively, for approximately $103.2 million, $7.3 million and $2.6 million, respectively. As of December 31, 2020, the Company had $41.3 million available for future stock repurchases, which has no expiration date. 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 and business conditions as well as other factors.
Common Stock Dividend
The following table presents the quarterly dividends declared per share of the Company’s common stock for the periods indicated:
The Company paid a total of approximately $25.1 million, $20.5 million and $18.8 million in cash dividends during 2020, 2019 and 2018, respectively.
In January 2018, the Company’s board of directors declared a $0.080 per share quarterly dividend for each quarter in 2018. In January 2019, the Company’s board of directors declared four quarterly cash dividends of $0.085 per share to be paid to stockholders of record at the end of each quarter in 2019. In October 2019, the Company’s board of directors raised the cash dividends per share with the declaration of five cash dividends, consisting of (a) a dividend of $0.01 per
share to be paid to stockholders of record at the end of the fourth quarter in 2019, that was in addition to the dividend of $0.085 per share to be paid to stockholders of record at the end of the fourth quarter in 2019 previously declared by the board in January 2019, and (b) a dividend of $0.095 per share to be paid to stockholders of record at the end of each quarter in 2020.
In April 2020, the Company’s board of directors raised the cash dividends with the declaration of three cash dividends of $0.105 per share (in lieu of the $0.095 per share previously announced in October 2019) to be paid to stockholders of record at the end of each of the second, third and fourth quarter in 2020. In July 2020, the Company’s board of directors raised the cash dividends further with the declaration of two cash dividends of $0.11 per share (in lieu of the $0.105 per share announced in April 2020) to be paid to stockholders of record at the end of each of the third and fourth quarter in 2020. In January 2021, the Company’s board of directors raised the quarterly cash dividend again by $0.02 per share with the declaration of four cash dividends of $0.13 per share to be paid to stockholders of record at the end of each quarter in 2021.
10. 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, the assumed issuance of awards under the stock purchase plan and contingently issuable performance-based awards, 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 included in the 2020, 2019 and 2018 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, 2020, 2019, and 2018, no outstanding stock awards were determined to be anti-dilutive and therefore were excluded from the computation of diluted earnings per share.
In July 2020, the Company’s board of directors approved a two-for-one stock split in the form of a stock dividend, payable on August 18, 2020, to stockholders of record as of the close of business on August 14, 2020. The Company’s stockholders received one additional share of common stock for each share of common stock held on August 14, 2020. The share and per share information for all periods presented in this Form 10-K has been adjusted for the effect of the stock split.
11. PROVISION (BENEFIT) 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 components of the provision (benefit) for income taxes are as follows:
The provision (benefit) for income taxes differs from the amount that would result by applying the applicable federal income tax rate to income before income taxes, as follows:
The Company’s effective tax rate is impacted by the geographic distribution of the Company’s world-wide earnings in lower-tax jurisdictions, federal research tax credits and the recognition of excess tax benefits related to share-based payments. These benefits were partially offset by foreign income subject to U.S. tax, known as global intangible low-taxed income. The Company’s primary jurisdiction where foreign earnings are derived is the Cayman Islands, which is a non-taxing jurisdiction. Income earned in other foreign jurisdictions was not material. The Company has not been granted any incentivized tax rates and does not operate under any tax holidays in any jurisdiction. Additionally, in 2018 the Company’s effective tax rate was favorably impacted by revisions to the Tax Act resulting in a $9.7 million income tax benefit.
The components of the net deferred income tax assets (liabilities) were as follows:
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, 2020, the Company continues to maintain a valuation allowance primarily as a result of capital losses for federal purposes, and on its California, New Jersey and Canada deferred tax assets as the Company believes that it is not more likely than not that the deferred tax assets will be fully realized.
As of December 31, 2020, the Company had utilized all of its federal research and development tax credit carryforwards. As of December 31, 2020, the Company had California research and development tax credit carryforwards of approximately $30.2 million (there is no expiration of research and development tax credit carryforwards for the state of California) and California net operating losses of $44.7 million which will begin to expire in 2032. As of December 31, 2020, the Company had Canadian scientific research and experimental development tax credit carryforwards of approximately $3.4 million and New Jersey research and experimental development tax credit carryforwards of approximately $0.7 million, which will start to expire in 2030 and 2026, respectively.
The Tax Act signed into law on December 22, 2017, generally allows companies to repatriate accumulated foreign earnings without incurring additional U.S. federal taxes beginning after December 31, 2017. Local foreign and U.S. states taxes may still be incurred upon repatriation. The Company has not provided for U.S. taxes on its undistributed earnings of foreign subsidiaries. The determination of the future tax consequences of the remittance of these earnings is not practicable.
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, 2020, 2019 and 2018, were $21.1 million, $19.0 million and $18.6 million, respectively. An income tax benefit of $11.1 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 had accrued interest and penalties of $0.1 million as of both December 31, 2020 and 2019, which have been recorded in long-term income taxes payable in the accompanying consolidated balance sheets.
As of December 31, 2020, the Company has concluded all U.S. federal income tax matters for the years through 2012. However, due to tax attributes, the IRS may calculate tax adjustments for subsequent years for positions taken prior to 2012. There are currently no pending income tax audits.
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 was issued by the Tax Court in December 2015. In February 2016, the Commissioner appealed the Tax Court decision. On July 24, 2018, the U.S. Ninth Circuit Court of Appeals reversed the U.S. Tax Court’s decision Altera Corp. v. Commissioner; the reversal was subsequently withdrawn. On June 7, 2019, the Ninth Circuit Court of Appeals overturned the U.S. Tax Court decision; finding that the Government had adequately supported in the record that stock-based compensation should be treated as an intangible development cost in a cost-sharing arrangement and Treasury’s position on the issue was not a policy change, holding stock-based compensation to be a compensable cost under IRC Section 482.
On February 10, 2020, Altera filed a petition for a writ of certiorari asking the Supreme Court to review the Ninth Circuit’s decision. The Supreme Court’s denied the petition for certiorari, and thus the Ninth Circuit’s decision stands. The decision above does not impact the Company as it treats stock-based compensation as a compensable cost under IRC Section 482.
12. LEASES AND COMMITMENTS:
Facilities and Leases
The Company owns its main executive, administrative, manufacturing and technical offices in San Jose, California. The Company also owns a research and development facility in New Jersey, a design center in Germany and a test facility in Switzerland. The Company’s leases consist of operating leases for administrative office spaces, research-and-development facilities and sales offices in various countries around the world. Effective January 1, 2019, the Company adopted Accounting Standards Update 2016-02, Leases (Topic 842), using the optional transition method. The Company determines if an arrangement is a lease at inception. Some lease agreements contain lease and non-lease components, which are accounted for as a single lease component. Total lease expense was $2.7 million, $2.5 million and $2.2 million in the years ended December 31, 2020, 2019 and 2018, respectively, while short-term and variable lease expenses were not material during these periods.
Balance sheet information related to leases was as follows:
Initial lease terms are determined at commencement and may include options to extend or terminate the lease when it is reasonably certain the Company will exercise the option. Remaining lease terms range from one to eight years, some of which include options to extend for up to six years, and some of which include options to terminate within one year. Leases with an initial term of twelve months or less are not recorded on the balance sheet. As the Company’s leases do not provide an implicit rate, the present value of future lease payments is determined using the Company’s incremental borrowing rate based on information available at commencement date.
Supplemental cash flows information related to leases was as follow:
Future minimum lease payments under all non-cancelable lease agreements as of December 31, 2020, are as follows:
Purchase Obligations
At December 31, 2020, the Company had no non-cancelable purchase obligations that were due beyond one year.
13. 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 April 1, 2016, Opticurrent, LLC filed a complaint against the Company in the United States District Court for the Eastern District of Texas alleging that the Company infringed one patent pertaining to transistor switch devices and seeking damages for the alleged infringement. The Company filed a motion to transfer the case to the Northern District of California, which the Court granted, and the case was assigned to a new judge in San Francisco following the transfer. On December 21, 2018, the Court granted the Company’s challenge to Opticurrent’s damages expert but denied the Company’s motion for summary judgment. Following a trial in February 2019, a jury issued a finding of direct infringement by the Company but found that the Company did not induce infringement, and awarded Opticurrent damages of $6.7 million. The Company challenged those findings in post-trial proceedings, and the Court granted one of the Company’s post-trial motions, reducing the damages award to $1.2 million. Although the Court of Appeals affirmed the original findings and the reduced damages award, the Company believes it has strong defenses, and intends to continue to vigorously defend itself against Opticurrent’s claims, including through a pending motion to set aside the judgment in view of a disclaimer that Opticurrent made during reexamination proceedings, which has been fully briefed and argued, with rulings expected in the coming months.
On June 19, 2019, Opticurrent, LLC filed a follow-on lawsuit in the United States District Court for the Northern District of California accusing more of the Company’s products of infringement and seeking damages for the alleged infringement of the same claim of the same patent asserted in the parties’ prior litigation, as described above. Limited discovery has taken place, but proceedings are currently stayed pending resolution of the Company’s motion to set aside the judgment in the parties’ prior litigation, and no schedule has yet been set for expert discovery, dispositive motions, or trial. The Company believes it has strong defenses, and intends to vigorously defend itself against Opticurrent’s claims, with appeals to follow if necessary.
On January 6, 2020, the Company filed a complaint against CogniPower LLC in the United States District Court for the District of Delaware for infringement of two of the Company’s patents and seeking a declaration of non-infringement with respect to patents that CogniPower had charged the Company’s customers with infringing, based on customer use of the Company’s products. In response, CogniPower filed a motion to dismiss the Company’s declaratory judgment claims on the basis that CogniPower had not threatened the Company directly with suit. That motion was granted, so CogniPower’s claims for infringement initially went forward separately in their lawsuit against the Company’s customers in the District of Delaware, but the Company filed a motion to intervene in that lawsuit and received a ruling allowing the Company to intervene in CogniPower’s customer lawsuit on February 1, 2021. Fact discovery and claim construction proceedings are now under way, but the Company believes it has strong claims and defenses, and intends to vigorously defend itself against CogniPower’s claims against the Company’s technology, with appeals to follow if necessary.
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.
14. RETIREMENT PLANS:
The Company sponsors a defined benefit pension plan (Pension Plan) for its Swiss subsidiary 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, 2020, 2019 and 2018. At December 31, 2020, the projected benefit obligation was $16.6 million, the plan assets were $9.7 million and the net pension liability was $6.9 million. As of December 31, 2019, the projected benefit obligation was $14.8 million, the plan assets were $8.2 million, and the net pension liability was $6.6 million.

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 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, 2020, 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, 2020, our internal control over financial reporting was effective.
The effectiveness of Power Integrations’ internal control over financial reporting as of December 31, 2020, 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 2020, 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 Stockholders and the Board of Directors of Power Integrations, Inc.
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of Power Integrations, Inc. and subsidiaries (the “Company”) as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2020, of the Company and our report dated February 5, 2021 expressed an unqualified opinion on those consolidated financial statements and included an explanatory paragraph relating to the Company’s adoption of Accounting Standards Update (ASU) 2016-02, Leases (Topic 842).
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Compensation Matters
On February 1, 2021, the Compensation Committee of the Board of Directors of Power Integrations, Inc. (the “Company”) took the following compensation actions with respect to the Company’s chief executive officer, chief financial officer, and other “named executive officers” as defined in Rule 402 of SEC Regulation S-K (collectively, the “Officers”).
2021 Performance-based Incentive Plan
Approved the 2021 Performance-based Incentive Plan (the “2021 PSU Plan”) as follows:
Each Officer, as described below, was granted performance stock units, referred to as “PSUs,” which will vest (referred to as a “payout” below) based on Company performance as against the 2021 PSU Plan’s established net revenue targets, non-GAAP operating income targets and strategic goals, each as established by the Compensation Committee. The 2021 target net revenue and non-GAAP operating income levels are intended to have difficulty in attainment levels consistent with the Company’s 2020 PSU Plan.
The portion of the performance stock units granted under the 2021 PSU Plan that will vest will be calculated independently for each of its net revenue, non-GAAP operating income and strategic goals components. “Net revenue” is as set forth in the Company’s annual report for 2021 to be filed with the Securities and Exchange Commission (“SEC”). “Non-GAAP operating income” means operating income for 2021 determined in accordance with GAAP but excluding the following items: (i) stock-based compensation expenses recorded under Accounting Standards Codification 718; (ii) amortization of acquisition-related intangible assets, and the fair-value write-up of acquired inventory; (iii) any other mergers and acquisitions related expenses; and (iv) any other adjustment made to arrive at the Company’s non-GAAP financial information as presented in the Company’s SEC filings. Further, in the event of any mergers, acquisitions or divestitures, or any patent or other litigation settlements or judgments, during the performance period, the net revenue and non-GAAP operating income targets shall be adjusted based on a revised plan approved by the Board of Directors. The strategic goals component is made up of five different strategic goals for the Company.
Weighting of the target components is as follows:
Net Revenue Component of the 2021 PSU Plan:
No payout will be made under the net revenue component of the 2021 PSU Plan if the Company’s 2021 actual net revenue does not exceed at least the established minimum amount of net revenue as set forth in the 2021 PSU Plan. To the extent 2021 actual net revenue is above the minimum amount of net revenue, the payout increases linearly from zero at the minimum amount of net revenue as set forth in the 2021 PSU Plan up to 100% of the net revenue component of the target when actual net revenue equals target net revenue in the 2021 PSU Plan. If 2021 actual net revenue is above the target amount of net revenue, then the payout for performance above target increases linearly from the target amount up to a maximum of 200% of the net revenue component of the target when actual net revenue equals or exceeds the established target to achieve the maximum payout under the net revenue component of the 2021 PSU Plan.
Non-GAAP Operating Income Component of the 2021 PSU Plan:
No payout will be made under the non-GAAP operating income component of the 2021 PSU Plan if the Company’s 2021 actual non-GAAP operating income does not exceed at least the established minimum amount of non-GAAP operating income as set forth in the 2021 PSU Plan. To the extent 2021 actual non-GAAP operating income is above the minimum amount of non-GAAP operating income, the payout increases linearly from zero at the minimum amount of non-GAAP operating income as set forth in the 2021 PSU Plan up to 100% of the non-GAAP operating income component of the target when actual non-GAAP operating income equals target non-GAAP operating income in the 2021 PSU Plan. If 2021 actual non-GAAP operating income is above the target amount of non-GAAP operating income, then
the payout for performance above target increases linearly from the target amount up to a maximum of 200% of the non-GAAP operating income component of the target when actual non-GAAP operating income equals or exceeds the established target to achieve the maximum payout under the non-GAAP operating income component of the 2021 PSU Plan.
Strategic Goals Component of the 2021 PSU Plan:
Each of the five goals in the strategic goals component of the 2021 PSU Plan is assigned a weighting percentage, which percentages range from 2% to 14%, and which collectively add up to 30%. If the Company’s 2021 actual achievement of a goal does not exceed at least the established minimum requirement for a particular goal, then no amount is earned for that goal. To the extent 2021 actual performance for a goal is better than the established minimum for the goal, then the payout increases linearly from zero at the minimum amount of performance as set forth in the 2021 PSU Plan up to 100% of the amount for that goal when actual performance equals target performance for that goal in the 2021 PSU Plan. To the extent 2021 actual performance for a goal is better than the established target for the goal, then the payout for performance above target increases linearly from the target amount actual performance, up to a maximum of 200% for the specific goal when actual performance equals or exceeds the established target to achieve the maximum payout under the specific goal as set forth in the 2021 PSU Plan.
2021 Target Performance Stock Units
Approved the 2021 target performance stock units for the Officers as follows:
The actual number of shares subject to the performance stock units is twice the target level shown in the table above to enable the payout of up to 200% of the target amount if the actual net revenue, non-GAAP operating income and strategic goals achievement equal or exceed the established levels to achieve the maximum amount of the 2021 PSU Plan.
2021 Restricted Stock Unit Grants
Approved restricted stock units, referred to as “RSUs,” grants to the following Officers:
The RSU grants will be effective on the grant date. Twenty-five percent (25%) of the RSUs vest on the one-year anniversary of the vesting commencement date (as specified in the Officers’ RSU award agreements), and an additional twenty-five percent (25%) of the RSUs vest annually over the next three (3) years thereafter, subject to the respective Officer’s continuous service.
2021 Long-term Performance-Based Incentive Plan
Approved the 2021 Long-term Performance-Based Incentive Plan (“2021 PRSU Plan”) as follows:
Each Officer, as described below, was granted long term performance stock units, referred to as “PRSUs,” which will vest (referred to as a “payout” below) based on Company revenue performance as against the 2021 PRSU Plan’s established three-year (years 2021, 2022 and 2023) compound annual growth rate (“CAGR”) of revenue as measured against a specified index of the analog semiconductor industry CAGR (the “Index”). The level of performance of the Company’s three-year revenue CAGR as against the Index is intended to have a difficulty in attainment level consistent
with the Company’s 2020 PRSU Plan. The portion of the performance stock units that will vest will be calculated based on the Company’s actual three-year revenue CAGR as compared to the Index and awarded in early 2024 upon approval by the Compensation Committee. In the event of any mergers, acquisitions or divestitures, or any patent or other litigation settlements or judgments, during the performance period, the Company’s target three-year revenue CAGR as against the Index shall be adjusted based on a revised plan approved by the Board of Directors.
No payout will be made in early 2024 under the 2021 PRSU Plan if the Company’s actual three-year revenue CAGR does not exceed at least the established minimum amount as measured against the Index as set forth in the 2021 PRSU Plan. To the extent the Company’s actual three-year revenue CAGR exceeds at least the established minimum amount as measured against the Index as set forth in the 2021 PRSU Plan, the payout increases linearly from zero at the minimum CAGR performance level as measured against the Index as set forth in the 2021 PRSU Plan up to 100% when the Company’s actual three-year revenue CAGR equals the target at the specified level as set forth in the 2021 PRSU Plan. If the Company’s actual three-year revenue CAGR exceeds the target, then the payout for performance above target increases linearly from the target amount up to a maximum of 200% of the target when the Company’s actual three-year revenue CAGR equals or exceeds the established amount to achieve the maximum payout as set forth in the 2021 PRSU Plan. Except to the extent provided in the executive officer benefits agreements between the Company and each Officer, each Officer must be employed by the Company through the end of the performance period to receive stock pursuant to the PRSUs under the 2021 PRSU Plan.
2021 Target PRSUs
Approved the target 2021 PRSUs for the Officers as follows:
The actual number of shares subject to the PRSUs is twice the target level shown in the table above to enable the payout of up to 200% of the target amount if actual net revenue equals or exceeds the established level to achieve the maximum amount of the 2021 PRSU Plan.
2021 Salaries
Approved the 2021 salaries for the Officers, to be effective at the end of March 2021, as follows:
