SUMMARY RISK FACTORS

Our business is subject to varying degrees of risk and uncertainty. Investors should consider the risks and uncertainties summarized below, as well as the risks and uncertainties discussed in Part I, Item 1A, “Risk Factors” of this Annual Report on Form 10-K. Investors should also refer to the other information contained or incorporated by reference in this Annual Report on Form 10-K for the year ended December 31, 2021, including our consolidated financial statements and related notes, and our other filings made from time to time with the Securities and Exchange Commission. Our business operations could also be affected by factors that we currently consider to be immaterial or that are unknown to us at the present time. If any of these risks occur, our business, financial condition, and results of operations could be materially and adversely affected, and the trading price of our common stock could decline.

Our business is subject to the following principal risks and uncertainties:

•The ongoing effects of the COVID-19 pandemic could disrupt our business or the business of our customers or suppliers, and as such, may adversely affect our financial condition.

•The continued uncertain global economic environment and volatility in global credit and financial markets could materially and adversely affect our business and results of operations.

•If we fail to meet the evolving needs of our markets, identify new products, services or technologies, or successfully compete in our target markets, our revenue and financial results will be adversely impacted.

•Our product strategy may not address the demands of our target customers and may not lead to increased revenue in a timely manner or at all, which could materially adversely affect our results of operations and limit our ability to grow.

•Achieving design wins involves lengthy competitive selection processes that require us to incur significant expenditures prior to generating any revenue or without any guarantee of any revenue related to this business. If we fail to generate revenue after incurring substantial expenses to develop our products, our business and operating results would suffer.

•If we fail to retain or attract the specialized technical and management personnel required to successfully operate our business, it could harm our business and may result in lost sales and diversion of management resources.

•We have significantly fewer financial resources than most of our competitors, which limits our ability to implement new products or enhancements to our current products, which in turn could adversely affect our future sales and financial condition.

•If we are not profitable in the future, we may be unable to continue our operations.

•A significant amount of our revenue comes from a limited number of customers and distributors exposing us to increased credit risk and subjecting our cash flow to the risk that any of our customers or distributors could decrease or cancel its orders.

•We generally do not have long-term purchase commitments from our customers and if our customers cancel or change their purchase commitments, our revenue and operating results could suffer.

•Our revenue and operating results can fluctuate from period to period, which could cause our share price to decline.

•If we are unable to generate sufficient cash from operations and are forced to seek additional financing alternatives our working capital may be adversely affected and our shareholders may experience dilution or our operations may be impaired.

•We license our intellectual property, which exposes us to risks of infringement or misappropriation, and may cause fluctuations in our operating results.

•We face a number of risks as a result of the concentration of our operations and customers in Asia.

•Our operations in Asia expose us to heightened risks due to natural disasters.

•We face additional risks associated with our operations in China and our results of operations and financial position may be harmed by changes in China's political, economic or social conditions or changes in U.S.-China relations.

•Our international operations expose us to risks resulting from the fluctuations of foreign currencies.

•If we are unable to maintain effective disclosure controls and internal controls over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports, and the market price of our common stock may be materially and adversely affected.

•Our dependence on selling to distributors and integrators increases the complexity of managing our supply chain and may result in excess inventory or inventory shortages.

•We may be unable to successfully manage any future growth, including the integration of any acquisition or equity investment, which could disrupt our business and severely harm our financial condition.

•Continued compliance with regulatory and accounting requirements will be challenging and will require significant resources.

•Regulations related to conflict minerals may adversely impact our business.

•Dependence on a limited number of sole-source, third-party manufacturers for our products exposes us to possible shortages based on low manufacturing yield, errors in manufacturing, uncontrollable lead-times for manufacturing, capacity allocation, price increases with little notice, volatile inventory levels and delays in product delivery, any of which could result in delays in satisfying customer demand, increased costs and loss of revenue.

2

•Our highly integrated products and high-speed mixed signal products are difficult to manufacture without defects and the existence of defects could result in increased costs, delays in the availability of our products, reduced sales of products or claims against us.

•The development of new products is extremely complex and we may be unable to develop our new products in a timely manner, which could result in a failure to obtain new design wins and/or maintain our current revenue levels.

•Intense competition in our markets may reduce sales of our products, reduce our market share, decrease our gross profit and result in large losses.

•If we are not able to respond to the rapid technological changes and evolving industry standards in the markets in which we compete, or seek to compete, our products may become less desirable or obsolete.

•We use a customer-owned tooling process for manufacturing most of our products, which exposes us to the possibility of poor yields and unacceptably high product costs.

•We depend on manufacturers of our semiconductor products not only to respond to changes in technology and industry standards but also to continue the manufacturing processes on which we rely.

•Shortages of materials used in the manufacturing of our products and other key components of our customers’ products may increase our costs, impair our ability to ship our products on time and delay our ability to sell our products.

•Because of our long product development process and sales cycles, we may incur substantial costs before we earn associated revenue and ultimately may not sell as many units of our products as we originally anticipated.

•Our developed software may be incompatible with industry standards and challenging and costly to implement, which could slow product development or cause us to lose customers and design wins.

•The competitiveness and viability of our products could be harmed if necessary licenses of third-party technology are not available to us on terms that are acceptable to us or at all.

•Our limited ability to protect our IP and proprietary rights could harm our competitive position by allowing our competitors to access our proprietary technology and to introduce similar products.

•Our products are characterized by average selling prices that can decline over relatively short periods of time, which will negatively affect our financial results unless we are able to reduce our product costs or introduce new products with higher average selling prices.

•The cyclical nature of the semiconductor industry may lead to significant variances in the demand for our products and could harm our operations.

•If we are unable to implement our strategy to expand our PRC operations, our ability to access capital, customers, and talent in China could suffer, which in turn may materially and adversely affect our worldwide growth and revenue potential.

•Even if we complete a listing on The Shanghai Exchange’s Science and Technology Innovation Board, known as the STAR Market (the “Listing”), we may not achieve the results contemplated by our business strategy and our strategy for growth in the PRC may not result in increases in the price of our common stock.

•Pixelworks Semiconductor Technology (Shanghai) Co., Ltd’s (“PWSH”) status as a publicly traded company that is controlled, but less than wholly owned, by Pixelworks could have an adverse effect on us.

•The Listing is relatively new, and as a result, it is difficult to predict the effect of the proposed Listing, which may in turn negatively affect the price of our common stock on the Nasdaq Global Market.

•If the Listing is completed, Pixelworks and PWSH both will be public reporting companies, but each will be subject to separate, and potentially inconsistent, accounting and disclosure requirements, which may lead to investor confusion or uncertainty that could cause decreased demand for, or fluctuations in the price of, one or both of the companies’ publicly traded shares.

•The price of our common stock has and may continue to fluctuate substantially.

NOTE REGARDING COVID-19

    In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic, and the virus continues to exist in areas where we operate and sell our products and services. Several public health organizations have recommended, and many local governments have implemented, certain measures to slow and limit the transmission of the virus, including various social distancing ordinances, which has resulted in a significant deterioration of economic conditions in many of the countries in which we operate.

    The spread of COVID-19 has caused us to modify our business practices, including implementing work-from-home policies and restricting travel by our employees. To date, our Shanghai and Shenzhen offices are operating with full in-person staffing, our offices and supply chain partners in Taiwan are fully functional, and our offices in Japan and North America are fully operational, working both in-office and remotely.

COVID-19 may also affect the operations of our suppliers and customers, as their own workforces and operations are disrupted by the pandemic, which could result in the interruption of our distribution system, temporary or long-term disruption in our supply chains, or delays in the delivery of our product. While we expect the impacts of COVID-19 to be temporary, the disruptions caused by the virus have negatively affected our revenue and results of operations in 2020 and 2021. For example, our revenues for fiscal year 2020 were lower than initially anticipated and our revenues for 2021 continued to be negatively impacted by COVID-19.

The impact of the pandemic on our business, as well as the business of our suppliers and customers, and the additional measures that may be needed in the future in response to it, including cost-saving measures, will depend on many factors beyond our control and knowledge. We will continually monitor the situation to determine what actions may be necessary or appropriate to address the impact of the pandemic, which may include actions mandated or recommended by federal, state or local authorities.

PART I

Item 1.Business.

Overview

Pixelworks is a leading provider of high-performance and power-efficient visual processing solutions that bridge the gap between video content formats and rapidly advancing display capabilities. We develop and market semiconductor and software solutions that enable consistently high-quality, authentic viewing experiences in a wide variety of applications from cinema to smartphones. Our primary target markets include Mobile (smartphone, gaming and tablet), Home Entertainment (TV, personal video recorder ("PVR"), over-the-air ("OTA") and projector), Content (creation, remastering and delivery), and Business & Education (projector).

We were one of the first companies to commercially launch a video System on Chip ("SoC") capable of deinterlacing 1080i HDTV signals and one of the first companies with a commercial dual-channel 1080i deinterlacer integrated circuit. Our Topaz product line was one of the industry’s first single-chip SoC for digital projection. We first introduced our motion estimation / motion compensation technology ("MEMC") for TVs and in recent years introduced a mobile-optimized MEMC solution for smartphones, one of several unique features in our mobile-optimized X5 visual processor. In 2019, we introduced our Hollywood award-winning TrueCut® video platform, the industry’s first motion grading technology that allows fine tuning of motion appearance in cinematic content for a wide range of frame rates, shutter angles and display types.

Our solutions enable worldwide manufacturers to offer leading-edge consumer electronics and professional display products, as well as video delivery and streaming solutions for content service providers. Our core visual display processing technology intelligently processes digital images and video from a variety of sources and optimizes the content for a superior viewing experience. Our video coding technology reduces storage requirements, significantly reduces bandwidth constraint issues and converts content between multiple formats to enable seamless delivery of video, including OTA streaming, while also maintaining end-to-end content security.

Rapid growth in video and gaming consumption, combined with the move towards high frame rate / refresh rate displays, especially in mobile, is increasing the demand for our visual processing and video delivery solutions. Our technologies can be applied to a wide range of devices from large-screen projectors to cinematic big screens, to low-power mobile tablets, smartphones, high-quality video infrastructure equipment and streaming devices. Our products are architected and optimized for power, cost, bandwidth, and overall system performance, according to the requirements of the specific application. On occasion, we have also licensed our technology.

As of December 31, 2021, we held an intellectual property portfolio of 335 patents related to the visual display of digital image data. We focus our research and development efforts on developing video algorithms that improve quality, and architectures that reduce system power, cost, bandwidth and increase overall system performance and device functionality. We seek to expand our technology portfolio through internal development and co-development with business partners, and we continually evaluate acquisition opportunities and other ways to leverage our technology into other high-value markets.

During the third quarter of 2021, we engaged in a strategic plan to re-align our mobile, projector, and video delivery businesses to improve their focus on the Asia-centered customers and employee stakeholders of those businesses. The global center of the mobile, projector, and video delivery businesses continues to be in Asia, and the steps we have taken to date and going forward are intended to improve our ability to access capital, customers, and talent. We have operated our primary R&D center in Asia for over 15 years and feel that the time is right to take advantage of that existing footprint and develop our subsidiary, Pixelworks Semiconductor Technology (Shanghai) Co., Ltd. (or "PWSH") as a full profit-and-loss center underneath Pixelworks, Inc. for the mobile, projector, and video delivery businesses. Most of these steps were completed before the end of 2021.

This plan will further enable PWSH to seek qualification to file an application for an initial public offering on the Shanghai Stock Exchange’s Science Technology Innovation Board, known as the STAR Market (the “Listing”). We believe that the Listing will have many benefits, including improved access to new capital markets and the funding of its growth worldwide. We presently intend to qualify PWSH to apply for the Listing so that the Listing is consummated in 2023. The process of going public on the STAR Market includes several periods of review and, therefore, is a lengthy process. There is no guarantee that PWSH will be approved for a Listing at any point in the future.

Key Markets

We target four key market segments with our products and solutions including:

Market	Products
Mobile (Smartphone, Gaming, Tablet)	Visual processors and software
Home Entertainment (TV, PVR, OTA, Projector)	XCode® transcoding solutions and visual processors
Content (Creation, Remastering, Delivery)	TrueCut® platform for content creators/video providers
Business and Education (Projectors)	Visual processors

Bridging the Performance Gap Between Content Formats and Device Capabilities

In recent years, display refresh rates for TVs, tablets and smartphones have been advancing faster than the ability of content formats to keep up. The refresh rate, measured in Hertz ("Hz"), is the number of times per second the display updates the image on screen to convey motion. Today, TV displays generally have a refresh rate of 120 Hz, while smartphones are now moving from 60 to 90 and 120 Hz. Despite this trend, the vast majority of produced video content exists only in 24-25 frames per second ("FPS"), while most gaming and user generated content is at 30 FPS. While frame rates for new game content is on the rise, the rendering, compute and thermal limits of today’s mobile processors often limit the effective frame rates to well below 60 FPS. The resulting mismatch between low frame rate content and high refresh rate screens creates artifacts, such as judder and strobing, that degrade video quality and destroy creative intent. The trend towards brighter, high dynamic range ("HDR") capable screens make these artifacts more noticeable to viewers. Visual quality is further impeded by power constraints and changes in ambient lighting, particularly in mobile devices.

Our technologies and solutions efficiently bridge the quality gap and enable the visual storytelling that is richer and true to creative intent. In fact, our TrueCut Motion Grading is the industry’s first solution to give filmmakers the ability to cinematically fine-tune motion blur, judder and frame-rate appearance and is used as part of the creative process to empower filmmakers to shoot at any frame-rate, then deliver a cinematically tuned, broader set of motion and frame rate appearances. While TrueCut technology enables creation of new content or remastering of existing content that preserves artistic intent across screens, from cinema to home TVs to smartphones, our mobile display processors and software bridge the quality gap for all existing content viewed on mobile devices, such as smartphones and tablets.

Display Trends

Display technologies have recently begun to transition from an era of higher resolutions, response times and frame rates, with lower power and thinner form factors, to one focused on higher contrast, brightness and more colors.

In mobile devices, Apple Inc. has brought wide color gamut to many of their devices including the iPhone, iPad Pro, MacBook Pro and iMac. These devices deliver the same color gamut used in digital cinema theatres ("DCI-P3"). Meanwhile, TV manufacturers including Samsung, TCL, Sony and LG are bringing high contrast, high brightness or HDR TVs based on organic light emitting diodes ("OLED") and local-dimming liquid crystal display ("LCD") panels to the living room. Furthermore, some premium and mid-tier smartphones and tablets from Apple, Samsung, Sony, LG and Huawei now include HDR as a standard feature.

Hardware improvements in color and contrast are of little value without content that can take advantage of them. In fact, a significant gap now exists between the vast majority of video content available to consumers and these emerging display devices.

•Contrast and Brightness: Almost all movies available to consumers today use the "Rec.709" ITU standard format. This format defines brightness levels up to around 100 "nits" (a standard measure of brightness), whereas HDR TVs are five to ten times brighter, from 540 nits upwards. Most mobile devices support over 400 nits and sometimes over 600 nits.

•Color Gamut: DCI-P3 has a 25% larger color gamut than Rec.709.

•Frame Rate: TVs commonly display at 120 frames per second (120 Hz) and up to 240 Hz on more sophisticated higher-end models. Many premium tier mobile displays were launched in 2020 with 120 Hz screens, which are quickly cascading down to lower price points. Some of the gaming smartphones now have displays that run at up to 144 Hz.

8

•Resolution: TVs have achieved 4k resolutions (3840x2160) and mobile devices today can achieve up to 3440x1440 resolution, and while some content is available in 4k resolution, most movies are only available in FHD or HD resolutions, which is typically 1920x1080 and 1280x720 respectively.

This gap between display capabilities and available content brings significant challenges to video display device manufacturers. Sophisticated video processing is required to accurately reproduce the intended video on today’s displays. We help bridge this gap between the display capabilities and available content with our visual processors and software and TrueCut® video platform for content creators and video providers.

Content formats are evolving to take advantage of these display improvements. For example, Dolby introduced the "Dolby Vision™" format for movies and devices, in order to allow consumers to realize the benefits of HDR and wide color gamut. The industry standards body Society of Motion Picture & Television Engineers released a format specification known as "HDR10" that similarly bridges the gap in contrast and color between content and devices. The Ultra-HD Blu-ray disk format and streaming services such as Netflix and Amazon Video now support 4k HDR, aided by improved compression standards such as H.265.

Managing many content formats across a rapidly evolving range of displays is a significant and growing challenge. Older content tends to not get upgraded to the newer formats, yet consumers expect all content to display correctly. As the number of content formats grow, the technology of video processing becomes increasingly complex.

Delivering the intent of the content creator requires sophisticated algorithms and hardware circuits. Frame-rate and motion incompatibilities require a significantly higher level of processing and more sophisticated algorithms in order to avoid creating new problems. Most TVs today include frame-rate conversion chips, but many reviewers complain about artifacts such as halos, breakup in the image and the so-called "soap opera effect". Unfortunately, without frame-rate conversion, the video can appear to have judder and blur at levels that have increased substantially as a result of the improvements in contrast, color and detail.

In addition to judder, high-resolution displays suffer from softness and smearing in motion sequences called motion blur. There are numerous causes of motion blur. The materials used in constructing pixels on the display take a finite amount of time to transition from one state to another. If this time is too long, the image does not update swiftly and motion sequences seem to smear or blur. For example, Hollywood movies, TV shows and other premium content are usually authored at 24 frames per second or 24 Hz. At this frame rate, the brain can easily notice the transition from one frame to the next. As the brain and eyes track objects in motion, they have to jump in discrete steps due to the low frame rate. This stop-start motion is perceived by the brain as motion blur, reducing the visible clarity and fidelity of objects in motion. Additionally, when a motion sequence is played on a digital display device, the new updated frame is drawn over the top of the still visible previous frame. This "hold" effect is perceived by the brain as blur.

Judder and motion blur artifacts are more noticeable on high contrast, wider gamut displays, regardless of screen size (for example, a 5-inch smartphone screen viewed from ten inches away appears to be the same size as a 60-inch large screen TV viewed from ten feet away). Our advanced video display processing provides original equipment manufacturers ("OEMs") with solutions that avoid or minimize these artifacts and help realize the potential of their investment in high-resolution displays. We believe the most effective method for removing both judder and reducing blur is MEMC technology. This technology is based on complex mathematical algorithms that insert additional, interpolated frames to create a new, faster sequence of frames that has smooth, continuous motion. This technique works for virtually all types of panel technology.

Video Consumption Trend

With the advent of digital video, it has become possible to deliver video to consumers in an ever-increasing number of ways. Traditional delivery mechanisms, such as over the air broadcasts, cable, satellite, DVDs and Blu-ray, are being supplemented with Internet streaming and download services. With these new video delivery options comes the ability to offer more services and improved quality.

According to recent studies by Cisco Systems, Inc. ("Cisco"), video will constitute 82% of all global consumer Internet traffic by 2022. Global IP video traffic and Internet video traffic will both grow four-fold from 2017 to 2022. Live Internet video will account for 17 percent of Internet video traffic by 2022. Live video will grow 15-fold from 2017 to 2022. This rapid increase in video consumption is being driven by a variety of connected digital video devices and applications that allow consumers to easily create, share and consume video. In particular, mobile video consumption is rapidly expanding. The "always on" and ease of use of mobile devices are helping to make them the preferred choice as the "first screen" for many consumers.

As more content becomes increasingly available via the Internet, consumers have more choices for how and where they can enjoy content. According to Cisco, by 2022 there will be 9.4 billion connected mobile devices across the globe.

Video and Gaming Market for Mobile Devices

Mobile devices have become the dominant driver of video consumption and growth. According to the Q3 2019 Global Video Index report from Brightcove, Inc., more than 62% of all video views are now on mobile devices. Video also continues to grow as a share of mobile traffic usage. According to the June 2020 Ericsson Mobility Report, video now constitutes 63% of global mobile traffic and will rise to a 76% share by 2025. The burgeoning global gaming market is dominated by the smartphone segment, with 2.5 billion users, according to NewZoo1, a leading market intelligence service covering gaming, mobile and eSports. In China alone, the number of mobile gamers is expected to reach 637 million with revenue of $32 billion by 2024, compared to $18.5 billion in 2019 – implying 73% growth over five years, according to Niko Partners’ May 2020 report, China Mobile Games Market.

Mobile display systems pose a number of unique challenges. Power is of primary importance, impacting form factor, cost and performance. As these systems have added more functionality, new features have had to compete for battery life, internal bandwidth and space. The addition of high-resolution displays has further increased the burden on these resources.

Using the same technology developed for large screen TVs is neither feasible nor desirable. The video display processing pipelines used in TVs consume many watts of power and would be unsuitable for battery powered systems. In TVs, the size constraints on electronics are significantly less stringent when compared to mobile systems. To furnish the mobile market with appropriate solutions, we have taken a holistic, system-wide view and re-invented its video display processing technology to fit within the mobile constraints of battery life, bandwidth, form factor and performance. This approach has enabled us to create technology that meets the power and size requirements of mobile as well as offering additional benefits such as reducing the bandwidth burden of high-resolution video and freeing up more bandwidth for the CPU and GPU.

The mobile market today is primarily comprised of smartphones and tablets. Our technology addresses both of these markets.

•Smartphones. Smartphones have become a popular choice for many consumers. International Data Corporation ("IDC") estimates that 1.52 billion smartphones will be sold in 2023. The resolution of smartphone displays is growing, while the color gamut and contrast is moving toward DCI-P3 and HDR. These improvements in displays actually exacerbate the quality issues of video playback, a growing problem as users increasingly use their smartphones as their primary form of video consumption.

•Tablets. The line between tablets and smartphones is becoming increasingly indistinct as more tablets are offering mobile connectivity and are now available in sizes similar to those of smartphones. Tablets offer broad appeal to consumers. With the display being the salient component of smartphones and tablets, and the rapidly increasing use of these devices for video consumption, we believe that the incorporation of video display processing is the next logical step.

As 5G network coverage rapidly expands worldwide, the availability of 5G chipsets targeting smartphones priced as low as $200 in 2021, should reinvigorate market growth given the increased speed and lower latency of the wireless connections. According to Counterpoint Research, 14% of smartphones sold in the U.S. in August 2020 included 5G connectivity. In a recent 2020 report, IDC projected the smartphone market to return to a full recovery by 2022 and that 5G smartphones would capture a 50% global share of shipments by 2023. In addition, service providers in some countries will also utilize 5G networks to provide fixed wireless broadband. We further believe our compelling mobile display processing functionality, combined with 5G capability, will help motivate consumers to replace their 3G and 4G phones at a faster rate than occurred in the past two years. Finally, a new smartphone category has emerged as top vendors have previewed foldable smartphones which serve as a phone, and a mini tablet when unfolded. As prices for this capability inevitably come down, and further competition emerges, we believe this new category, along with the rollout of 5G networks, can strengthen the mobile device market.

Business and Education Market for Digital Projectors

Increasingly affordable price points are driving continued adoption of digital projectors in business and education, as well as among consumers. Technology improvements are helping to reduce the size and weight of projection devices while increasing their performance. Projector models range from larger units designed to be permanently installed in a conference hall or other venue, to ultra-portable devices weighing fewer than two pounds for maximum portability. According to PMA Research Limited, the worldwide front projector market shipped 8.5 million units in 2020 and is forecasted to reach 12 million units by 2024.

The feature set of projection systems differs from that of a typical large-screen flat panel display such as a TV. This is primarily because the projector is a sharing and collaboration device while the TV is designed for direct consumption of content.

10

The front projection market serves several different areas such as business, education and home theater. Business users employ multimedia projectors to display both still and video presentation materials from PCs and other sources. Requirements for the business market include portability, compatibility with multiple software and hardware applications, and features that ensure simple operation. In education environments ranging from elementary schools to university campuses, projectors help teachers integrate media-rich instruction into classrooms. Home theater projector systems can drive large-screen displays for content consumption where flat panel displays are either economically not viable or physically incompatible for use.

Consistent with the trends of other consumer products, digital projectors are increasingly incorporating networking capabilities that enable the sharing of video and other content among multiple devices. This, in turn, is enabling new use models for digital projection in both the education and business environments. For example, one teacher can present the same material simultaneously in multiple classrooms, and students in different classrooms can display and discuss their work. Such connectivity allows instant access to content and sharing of content, which promotes interaction and collaboration among dispersed groups. In the business setting, this connectivity enables teleconferencing and the seamless sharing of content for more effective meetings.

Video Delivery Market for Home Entertainment

With the acquisition of ViXS Systems Inc. in August 2017, we expanded both our market presence and product portfolio. The video industry continues to evolve and adopt new video standards such as High Efficiency Video Coding, 4K Ultra HD and HDR. The technical and processing demands of these standards are complex and play directly into our core competencies. Our technologies for video delivery are highly integrated, low power and provide high quality video processing, allowing seamless connectivity between devices while maintaining end-to-end content security.

The home entertainment sub-markets that we address with our video delivery products include:

•Consumer Products - OEMs and Original Design Manufacturers ("ODMs") design products for the consumer electronics segments.

•OTA - Over the Air applications for single, dual, and quad streaming requirements. End users who want to either "cut the cord" or supplement their service offerings.

•IP Streaming - Network streaming devices capable of content portability, and support for your own screen (phone and tablet devices), deployed by service operators.

Consumer Products

High-resolution (UHD/4K), sustained bitrate decoding (100Mbit) and advanced video formats (HDR10, HDR10+) are key requirements for advanced personal video recorder ("PVR") products sold in the Japanese market, where the end consumers rate video quality as a key acquisition criteria. This advanced PVR market in Japan is experiencing growth as products move from 2K to UHD/4K formats. In addition, as the market introduces new broadcast technologies, like Advanced Digital Satellite Broadcast ("ADSB") in Japan, and ATSC 3.0 in Korea and North America, there are further growth opportunities in this market segment.

OTA

Subscribers to video content in the home are making changes and demanding choices. While content is freely available, if it is distributed over an operator network, or even simply over IP, there is a monthly re-transmit fee that is charged to the consumer. As the number of video subscribers to services such as cable TV has been declining, the monthly re-transmit fee has been increasing. These fee increases are leading more consumers to ‘cut the cord’ and replace their TV subscriptions with over the top ("OTT") video services and free OTA broadcast television. As part of their OTA experience, consumers are starting to require multiple stream support of concurrent channels, so various devices can view different channels at the same time.

11

IP Streaming

Related to OTA applications, the service operators that want to provide their own choice to their video subscribers are taking advantage of our IP Streaming applications. These re-use common platforms, and connect to the in-home infrastructure, either at the set top box level, or the Wi-Fi router level. This provides a centralized place where the management, and distribution of content can occur.

For service operators, the benefits are:

•Customer retention

•Reduced use of network bandwidth for free OTA channels

For consumers, the benefits are:

•One menu that provides aggregation of Linear, Video-on-Demand, OTT, and OTA content

•Reduced monthly fees related to lower re-transmission fees

Core Technologies and Products

We have developed a portfolio of advanced video algorithms and IP to address a broad range of challenges in digital video. We believe our technologies can significantly improve video quality and will become increasingly important as the popularity of video content consumption grows, and pixel densities, screen size and image quality increase. Our products are designed with a flexible architecture that allows us to combine algorithms and functional blocks of digital and mixed signal circuitry. Accordingly, our technologies can be implemented across multiple products, in combinations within single products and can be applied to a broad range of applications including smartphones, tablets, and projectors. The majority of our products include one or more technologies to provide optimal high-quality video display processing solutions to our customers, regardless of screen size.

Our core Video Display Processing technologies include:

•MotionEngine® MEMC. Our proprietary MEMC technology significantly improves the performance and viewing experience of any screen by addressing problems such as judder and motion blur. Unlike competitive solutions it also reduces halo effects that are a byproduct of MEMC. Halos are objectionable blurred regions that surround moving objects as the MEMC algorithms try to reconstruct missing image data caused by the concealing and revealing of objects as they pass over or behind one another. Removing halos dramatically improves image quality and is of particular importance on high-resolution displays where artifacts become more visible.

•AI Based Display Processing. The Pixelworks i6 processor dramatically improves video and image quality and sets a new standard for picture quality on both LCD and OLED mobile displays with a new AI-driven architecture and dynamic refresh rate support for up to 144 Hz. Its lightweight AI display inferencing augments the Company’s knowledge base, numerous real time inputs and fuzzy logic IP to adaptively and intelligently optimize overall picture quality for video, games and photos at low power, including real time SDR-to-HDR conversion and AI adaptive display.

•Advanced Scaling. As display resolutions continue to increase, there is a need to convert lower resolution content to higher resolution in order to display content properly. With the latest wave of high-resolution displays, the quality and quantity demands of scaling have increased significantly. Artifacts become more noticeable on these types of displays as they distract from the realism effect. In addition, with the availability of high-resolution content lagging behind the availability of high-resolution displays, high-quality scaling is required to ensure high resolution displays do not suffer when compared to Full-HD displays of the same size. Our advanced scaling is designed to ensure that up-conversion of lower resolution content is of the highest quality in maintaining the fidelity of image.

•Mobile Video Display Processing. We have developed innovative video display processing solutions that are designed to optimize power consumption for mobile devices. Beyond MEMC and advanced scaling, these mobile solutions provide the kind of improvements in color, contrast, sharpness and de-blur that are currently only found in high quality TVs today. Furthermore, this technology can reduce system power consumption and extend battery life.

•Transcoding/Decoding. Digital Delivery forms the bulk of not just video content, but all internet bandwidth today. However, throughout the entire chain from inception to consumption, there are multiple variations in bitrate, resolution, and codecs used for both audio and video. Transcoding is a fundamental technology used throughout this pipeline that leads to moving pictures viewed on TVs and mobile devices. The XCODE family of ASICs has enabled many devices within this pipeline, from the racks in some service providers all the way down to the home user watching broadcast OTA TV on a smartphone. XCODE technology provides solutions that deliver UHD Blu-ray PVRs with capability of transcoding recorded content suitable for viewing on smartphones. The technology supports today’s broadcast standards, such as ATSC 1.0, DVB/T/T2/S/S2, ISDB/T/S, and ADSB and is scalable to support upcoming broadcast standards such as ATSC 3.0.

12

•SDR to HDR Conversion. UHD video has standardized on a technology known as HDR to deliver higher dynamic range content. This has resulted in several competing HDR deployments like HDR10, HLG and HDR10+ with support by multiple industry giants. Our HDR conversion technology can not only convert between SDR (Standard Dynamic Range) and HDR10, it can also convert among HDR10, HLG and HDR10+ solving an interconnectivity problem between content formatted in one HDR format to Display devices that supports a different HDR standard.

Our product development strategy is to leverage our expertise in video display processing to address the evolving needs of our target markets. We plan to continue to focus our development resources to maintain our position in these markets by providing leading edge solutions for the advanced digital projection and video delivery markets and to enhance our video processing solutions for mobile markets. We deliver our technology in a variety of offerings, which take the form of single-purpose chips, highly integrated SoCs that incorporate specialized software, full solutions incorporating software and other tools and IP cores that allow our technology to be incorporated into third party solutions.

Our primary video display processor product categories include the following:

•ImageProcessor ICs. Our ImageProcessor ICs include embedded microprocessors, digital signal processing technology and software that control the operations and signal processing within high-end display systems. ImageProcessor ICs were our first product offerings and continue to comprise the majority of our business. We have continued to refine the architectures for optimal performance, manufacturing our products on process technologies that align with our customers’ requirements. Additionally, we provide a software development environment and operating system that enables our customers to more quickly develop and customize the "look and feel" of their products.

•Video Co-Processor ICs. Products in this category work with an image processor to post-process video signals to enhance the performance or feature set of the overall video solution (for example, by significantly reducing judder and motion blur). Our Video Co-Processor ICs can be used with our ImageProcessor ICs or with image processing solutions from other manufacturers, and in most cases can be incorporated without assistance from the supplier of the base image processor. This flexibility enables manufacturers to augment their existing or new designs to enhance their video display products.

•Transcoder ICs. Our Transcoder ICs include embedded microprocessors, digital signal processing technology and software that control the operations and signal processing for converting multiple bitrates, resolutions and codecs to provide bandwidth efficient video transmissions based on industry standard protocols. Our transcoder technology allows for single, dual and even quad streaming solutions for OTA products. Like our other ICs, we have continued to refine the architectures for optimal performance, manufacturing our products on process technologies that align with our customers’ requirements. Additionally, we provide a software development environment that enables our customers to more quickly develop and customize their products.

Customers, Sales and Marketing

The key focus of our global sales and marketing strategy is to achieve design wins with industry leading branded manufacturers in our target markets and to continue building strong customer relationships. Once a design win has been achieved, sales and marketing efforts are focused on building long-term mutually beneficial business relationships with our customers by providing superior technology and reducing their costs, which complements our customers’ product development objectives and meets their expectations for price-performance and time to market. Marketing efforts are focused on building market-leading brand awareness and preference for our solutions.

We utilize direct sales and marketing resources in China, Japan, Taiwan, and the U.S. as well as indirect resources in several regions. In addition to sales and marketing representatives, we have field application engineers who provide technical expertise and assistance to manufacturing customers on final product development.

Our global distribution channel is multi-tiered and involves both direct and indirect distribution channels, as described below:

•Distributors. Distributors are resellers in local markets who provide engineering support and stock our semiconductors in direct relation to specific manufacturing customer orders. Our distributors often have valuable and established relationships with our end customers, and in certain countries it is customary to sell to distributors. While a distributor's payment to us is not dependent upon the distributor’s ability to resell the product or to collect from the end customer, our distributors may provide longer payment terms to end customers than those we would offer. Sales to distributors accounted for 56% and 49% of revenue in 2021 and 2020 respectively.

13

One of our distributors, Tokyo Electron Device Ltd. represented more than 10% of revenue in each of 2021 and 2020, and accounted for more than 10% of accounts receivable as of December 31, 2021. Another distributor, Upstar Technology Limited accounted for more than 10% of revenue in 2021 and accounted for more than 10% of accounts receivable as of December 31, 2021 and 2020. No other distributor accounted for more than 10% of revenue in 2021 and 2020 or represented more than 10% of accounts receivable as of December 31, 2021 or 2020.

We have distributor relationships in Japan, China, Europe, Korea, Taiwan and the U.S.

•Direct Relationships. We have established direct relationships with companies that manufacture high-end display systems. Some of our direct relationships are supported by commission-based manufacturers’ representatives, who are independent sales agents that represent us in local markets and provide engineering support but do not carry inventory. Revenue through direct relationships accounted for 44% and 51% of total revenue in 2021 and 2020, respectively.

We have direct relationships with companies falling into the following three classifications:

•Integrators. Integrators are OEMs who build display devices based on specifications provided by branded suppliers.

•Branded Manufacturers. Branded manufacturers are globally recognized manufacturers who develop display device specifications and manufacture, market and distribute display devices either directly or through resellers to end-users.

•Branded Suppliers. Branded suppliers are globally recognized suppliers who develop display device specifications and then source them from integrators, typically in Asia, and distribute them either directly or through resellers to end-users.

Revenue attributable to our top five end customers together represented 76% and 58% of revenue in 2021 and 2020, respectively. End customers include customers who purchase directly from us as well as customers who purchase products indirectly through distributors. Sales to Seiko Epson Corporation represented more than 10% of revenue in each of 2021 and 2020, and accounted for more than 10% of accounts receivable as of December 31, 2021 and 2020. Sales to vivo Communication Technology Co. Ltd. represented more than 10% of revenue in 2021. No other end customer accounted for more than 10% of revenue in 2021 and 2020 or represented more than 10% of accounts receivable as of December 31, 2021 or 2020.

Seasonality

Our business is subject to seasonality related to the markets we serve and the location of our customers. For example, we have historically experienced higher revenue from the digital projector market in the third quarter of the year, and lower revenue in the first quarter of the year, as our Japanese customers reduce inventories in anticipation of their March 31 fiscal year end.

Geographic Distribution of Sales

Sales outside the U.S. accounted for approximately 97% and 93% of revenue in 2021 and 2020 respectively.

Financial information regarding our domestic and foreign operations is presented in "Note 14. Segment Information" in Part II, Item 8 of this Annual Report on Form 10-K.

Backlog

Our sales are made pursuant to customer purchase orders for delivery of standard products. The volume of product actually purchased by our customers, as well as shipment schedules, are subject to frequent revisions that reflect changes in both the customers’ needs and product availability. In light of industry practice and our own experience, we do not believe that backlog as of any particular date is indicative of future results.

Competition

The semiconductor industry is intensely competitive. Further, the markets for higher performance display and projection devices, including the markets for mobile devices, digital projectors and other applications demanding high quality video, are characterized by rapid technological change, evolving industry standards, compressed product life cycles and declining average selling prices. We believe the principal competitive factors in our markets include product performance, time to market, cost, functional versatility provided by software, customer relationships and reputation, patented innovative designs, levels of product integration, compliance with industry standards and system design cost. We believe we compete favorably with respect to these factors.

14

Our current products face competition from developers of application processors and specialized display controllers designed by merchant chip vendors, our customers, potential customers and display panel vendors. Additionally, new alternative display processing technologies and industry standards may emerge that compete with technologies we offer.

We also compete with specialized and diversified electronics and semiconductor companies that offer display processors or scaling components including: Actions Microelectronics Co., Ltd., ARM Holdings PLC, Dolby Laboratories, Inc., Egis Technology Inc., Hisilicon Technologies Co., Ltd., i-Chips Technology Inc., Lattice Semiconductor Corporation, MediaTek Inc., Novatek Microelectronics Corp., NVIDIA Corporation, Qualcomm Incorporated, Realtek Semiconductor Corp., Renesas Electronics America Inc., Socionext Inc., Solomon Systech (International) Ltd., STMicroelectronics N.V., Sunplus Technology Co., Ltd., Synaptics Incorporated, Texas Instruments Incorporated, Unisoc Communications, Inc., and other companies. Potential and current competitors may include diversified semiconductor manufacturers and the semiconductor divisions or affiliates of some of our customers, including: Apple Inc., Broadcom Inc., LG Electronics, Inc., MegaChips Corporation, Mitsubishi Digital Electronics America, Inc., NEC Corporation, Panasonic Corporation, Samsung Electronics Co., Ltd., Socionext Inc., ON Semiconductor Corporation, Seiko Epson Corporation, Sharp Electronics Corporation, Sony Corporation, and Toshiba America, Inc. In addition, start-up companies may seek to compete in our markets.

Research and Development

Low power research and development efforts are focused on the development of our solutions for the mobile device, digital projector and video delivery markets. Our development efforts are focused on pursuing higher levels of video performance, integration and new features in order to provide our customers with solutions that enable them to introduce market leading products and help lower final systems costs.

We have invested, and expect to continue to invest, significant resources in research and development activities. Our research and development expenses were $27.3 million and $25.0 million in 2021 and 2020, respectively. During 2021, we received a reimbursement related to a co-development arrangement with a customer for costs incurred in connection with our development of an integrated circuit ("IC") product. As a result of the reimbursement, our overall research and development expense was reduced by $4.0 million in 2021. There were no reductions to research and development expense related to co-development arrangements in 2020.

Manufacturing

Within the semiconductor industry we are known as a "fabless" company, meaning that we do not manufacture the semiconductors that we design and develop, but instead contract with a limited number of foundries and assembly and test vendors to produce all of our wafers and for completion of finished products. The fabless approach allows us to concentrate our resources on product design and development where we believe we have greater competitive advantages.

See "Risk Factors" in Part I, Item 1A of this Annual Report on Form 10-K for information on risks related to our manufacturing strategy and processes.    

Intellectual Property

We protect our projector, mobile, video delivery and TrueCut businesses with a combination of nondisclosure agreements and patent, copyright, trademark and trade secret laws to protect the algorithms, design and architecture of our technology. As of December 31, 2021, we held 335 patents and have 9 patent applications pending, compared to 338 patents and 9 patent applications pending as of December 31, 2020. The patents we hold relate generally to improvements in the visual display of digital image data including, but not limited to, improvements in image scaling, image correction, automatic image optimization and video signal processing for digital displays. Our U.S. and foreign patents are generally enforceable for 20 years from the date they were filed. Accordingly, our issued patents have from approximately 1 to 18 years remaining in their respective term, depending on their filing dates. We believe that the remaining term of our patents is adequate relative to the expected lives of our related products.

We intend to seek patent protection for other significant technologies that we have already developed and expect to seek patent protection for future products and technologies as necessary. Patents may not be issued as a result of any pending applications and any claims allowed under issued patents may be insufficiently broad to protect our technology. Existing or future patents may be invalidated, diluted, circumvented, challenged or licensed to others. Furthermore, the laws of certain foreign countries in which our products are or may be developed, manufactured or sold, including various countries in Asia, may not protect our products or intellectual property rights in the same manner and to the same extent as do the laws of the U.S. and, thus, make the possibility of piracy of our technology and products more likely in these countries.

15

The semiconductor industry is characterized by vigorous protection of intellectual property rights, which have resulted in significant and often protracted and expensive litigation. We, our customers or our foundries from time to time may be notified of claims that we may be infringing patents or other intellectual property rights owned by third parties. Litigation by or against us relating to patent infringement or other intellectual property matters could result in significant expense to us and divert the efforts of our technical and management personnel, whether or not such litigation results in a determination favorable to us. In the event of an adverse result in any such litigation, we could be required to pay substantial damages, cease the manufacture, use and sale of infringing products, expend significant resources to develop non-infringing technology, discontinue the use of certain processes or obtain licenses to the infringing technology. We may not be able to settle any alleged patent infringement claim through a cross-licensing arrangement. In the event any third party made a valid claim against us, our customers or our foundries, and a license was not made available to us on terms that are acceptable to us or at all, we would be adversely affected.

See "Risk Factors" in Part I, Item 1A, and "Note 11. Commitments and Contingencies" in Part II, Item 8 of this Annual Report on Form 10-K for information on various risks related to intellectual property.

Environmental Matters

Environmental laws and regulations are complex, change frequently and have tended to become more stringent over time. We have incurred, and may continue to incur, significant expenditures to comply with these laws and regulations and we may incur additional capital expenditures and asset impairments to ensure that our products and our vendors’ products are in compliance with these regulations. We would be subject to significant penalties for failure to comply with these laws and regulations.

See "Risk Factors" in Part I, Item 1A of this Annual Report on Form 10-K for information on various environmental risks.

Employees

As of December 31, 2021, we had a total of 217 employees, the majority of which were full-time, compared to 197 employees as of December 31, 2020.

Item 1A.Risk Factors.

The following risks could materially and adversely affect our business, financial condition, and results of operations, and the trading price of our common stock could decline. These risk factors do not identify all of the risks that we face. Our business operations could also be affected by factors that we currently consider to be immaterial or that are unknown to us at the present time. Investors should also refer to the other information contained or incorporated by reference in this Annual Report on Form 10-K for the year ended December 31, 2021, including our consolidated financial statements and related notes, and our other filings made from time to time with the Securities and Exchange Commission ("SEC").

Risks Related to COVID-19

The ongoing effects of the COVID-19 pandemic could disrupt our business or the business of our customers or suppliers, and as such, may adversely affect our financial condition.

Our business, the businesses of our customers, and the businesses of our suppliers could be materially and adversely affected by the effects of the COVID-19 pandemic and the related governmental, business and community responses to it. Additionally, the economies and financial markets of many countries have been impacted by the pandemic, and the longevity and significance of the resulting economic impact is currently unknown. A significant economic downturn could materially and adversely affect our end customers, and thus could negatively impact demand for our products and our operating results. 

In response to the COVID-19 pandemic, many state governments in the U.S. issued restrictive orders, including “shelter in place” or “stay at home” orders, that restricted its residents from leaving their homes or returning to work. At Pixelworks, our offices in Japan and North America are currently operating in office and remotely. The potential future impact of any “stay at home” orders or other similar COVID-related restraints on movement, may adversely impact the efficiency and effectiveness of our organization, as well as the operations of our suppliers and customers. We face additional risks and challenges related to having a portion of our workforce working from home, including added pressure on our IT systems and the security of our network, and new challenges as our team adjusts to online collaboration. Additionally, our sales team may not be able to make sales calls to current and potential customers at the same volume as they did prior to the outbreak of the pandemic as they juggle varying competing interests. Also, our ability to make in-person sales calls may be affected in areas with stay at home orders or other restrictions in place, which may, in turn, affect our revenues.

The outbreak of COVID-19 may put additional pressures on our supply chain, including temporary or long-term disruption or delays. If the impact of an outbreak continues for an extended period, it could adversely impact our supply chain and the growth of our revenues. COVID-19 may result in supply shortages of our products or our ability to import, export or sell product to customers in both the U.S. and international markets. Any decrease, limitations or delays on our ability to import, export, or sell our products would harm our business. 

The continued uncertain global economic environment and volatility in global credit and financial markets could materially and adversely affect our business and results of operations.

The state of the global economy continues to be uncertain. As a result of these conditions, our manufacturers, vendors and customers might experience deterioration of their businesses, cash flow shortages and difficulty obtaining financing, which could result in interruptions or delays in the performance of any contracts, reductions and delays in customer purchases, delays in or the inability of customers to obtain financing to purchase our products, and bankruptcy of customers. Furthermore, the constraints in the capital and credit markets, may limit the ability of our customers to meet their liquidity needs, which could result in an impairment of their ability to make timely payments to us and reduce their demand for our products, adversely impacting our results of operations and cash flows. This environment has also made it difficult for us to accurately forecast and plan future business activities.

Company Specific Risks

If we fail to meet the evolving needs of our markets, identify new products, services or technologies, or successfully compete in our target markets, our revenue and financial results will be adversely impacted.

Pixelworks designs, develops and markets visual processing and advanced media processing solutions in the mobile video, digital projection and video delivery markets. Our success depends to a significant extent on our ability to meet the evolving needs of these markets and to enhance our existing products, solutions and technologies. In addition, our success depends on our ability to identify emerging industry trends and to develop new products, solutions and technologies. Our existing markets and products and new markets and products may require a considerable investment of technical, financial, compliance, sales and marketing resources.

We cannot assure you that our strategic direction will result in innovative products and technologies that provide value to our customers and partners. If we fail to anticipate the changing needs of our target markets and emerging technology trends, or adapt that strategy as market conditions evolve, in a timely manner to exploit potential market opportunities our business will be harmed. In addition, if demand for products and solutions from these markets is below our expectations, if we fail to achieve consumer or market acceptance of them or if we are not able to develop these products and solutions in a cost effective or efficient manner, we may not realize benefits from our strategy.

Our target markets remain extremely competitive, and we expect competition to intensify as current competitors expand their product and/or service offerings, industry standards continue to evolve and new competitors enter these markets. If we are unable to successfully compete in our target markets, demand for our products, solutions and technologies could decrease, which would cause our revenue to decline and our financial results to suffer.

Our product strategy, which is targeted at markets demanding superior video and digital image quality as well as efficient video delivery, may not address the demands of our target customers and may not lead to increased revenue in a timely manner or at all, which could materially adversely affect our results of operations and limit our ability to grow.

We have adopted a product strategy that focuses on our core competencies in visual display processing and delivering high levels of video and digital image quality. With this strategy, we continue to make further investments in the development of our image processor architecture for the digital projector market, with particular focus on adding increased performance and functionality. For the mobile device market, our strategy focuses on implementing our intellectual property ("IP") to improve the video performance of our customers’ image processors through the use of our MotionEngine® advanced video co-processor integrated circuits. This strategy is designed to address the needs of the high-resolution and high-quality segment of these markets. Such markets may not develop or may take longer to develop than we expect. We cannot assure you that the products we are developing will adequately address the demands of our target customers, or that we will be able to produce our new products at costs that enable us to price these products competitively.

Achieving design wins involves lengthy competitive selection processes that require us to incur significant expenditures prior to generating any revenue or without any guarantee of any revenue related to this business. If we fail to generate revenue after incurring substantial expenses to develop our products, our business and operating results would suffer.

We must achieve "design wins" that enable us to sell our semiconductor solutions for use in our customers’ products. These competitive selection processes typically are lengthy and can require us to incur significant research and development expenditures and dedicate scarce engineering resources in pursuit of a single customer opportunity. We may not achieve a design win and may never generate any revenue despite incurring significant research and development expenditures. This could cause us to lose revenue and require us to write off obsolete inventory and could weaken our position in future competitive selection processes.

18

Even if our product strategy is properly targeted, we cannot assure you that the products we are developing will lead to an increase in revenue from new design wins. To achieve design wins, we must design and deliver cost-effective, innovative and integrated semiconductors that overcome the significant costs associated with qualifying a new supplier and which make developers reluctant to change component sources. Additionally, potential developers may be unwilling to select our products due to concerns over our financial strength. Further, design wins do not necessarily result in developers ordering large volumes of our products. Developers can choose at any time to discontinue using our products in their designs or product development efforts. A design win is not a binding commitment by a developer to purchase our products, but rather a decision by a developer to use our products in its design process. Even if our products are chosen to be incorporated into a developer’s products, we may still not realize significant revenue from the developer if its products are not commercially successful or it chooses to qualify, or incorporate the products, of a second source. Additionally, even if our product strategy is successful at achieving design wins and increasing our revenue, we may continue to incur operating losses due to the significant research and development costs that are required to develop competitive products for the digital projection market and mobile market.

System security and data protection breaches, as well as cyber-attacks, could disrupt our operations, reduce our expected revenue and increase our expenses, which could adversely affect our stock price and damage our reputation.

Security breaches, computer malware and cyber-attacks have become more prevalent and sophisticated in recent years. These attacks have occurred on our systems in the past and are expected to occur in the future. Experienced computer programmers, hackers and employees may be able to penetrate our security controls and misappropriate or compromise our confidential information, or that of our employees or third parties. These attacks may create system disruptions or cause shutdowns. For portions of our IT infrastructure, including business management and communication software products, we rely on products and services provided by third parties. These providers may also experience breaches and attacks to their products which may impact our systems. Data security breaches may also result from non-technical means, such as actions by an employee with access to our systems.

Actual or perceived breaches of our security measures or the accidental loss, inadvertent disclosure or unapproved dissemination of proprietary information or sensitive or confidential data about us, our partners, our customers or third parties could expose the parties affected to a risk of loss, or misuse of this information, resulting in litigation and potential liability, damage to our brand and reputation or other harm to our business. Our efforts to prevent and overcome these challenges could increase our expenses and may not be successful. We may experience interruptions, delays, cessation of service and loss of existing or potential customers. Such disruptions could adversely impact our ability to fulfill orders and interrupt other critical functions. Delayed sales, lower margins or lost customers as a result of these disruptions could adversely affect our financial results, stock price and reputation.

If we fail to retain or attract the specialized technical and management personnel required to successfully operate our business, it could harm our business and may result in lost sales and diversion of management resources.

Our success depends on the continued services of our executive officers and other key management, engineering, and sales and marketing personnel and on our ability to continue to attract, retain and motivate qualified personnel. Competition for skilled engineers and management personnel is intense within our industry, and we may not be successful in hiring and retaining qualified individuals. For example, we have experienced, and may continue to experience, difficulty and increased compensation expense in order to hire and retain qualified engineering personnel in our Shanghai design center. The loss of, or inability to hire, key personnel could limit our ability to develop new products and adapt existing products to our customers’ requirements, and may result in lost sales and a diversion of management resources. Any transition in our senior management team may involve a diversion of resources and management attention, be disruptive to our daily operations or impact public or market perception, any of which could have a negative impact on our business or stock price.

19

We may not fully realize the estimated savings from our restructurings in a timely manner or at all, and our restructuring programs may result in business disruptions and decrease productivity. Any of the foregoing would negatively affect our financial condition and results of operations.

From time to time, we may have the need to execute restructuring plans to make the operation of the Company more efficient. We may not be able to implement our restructuring programs as planned, and we may need to take additional measures to fulfill the objectives of our restructuring. The anticipated expenses associated with our restructuring programs may differ from or exceed our expectations, and we might not be able to realize the full amount of estimated savings from the restructuring programs in a timely manner or at all. Additionally, our restructuring plans may result in business disruptions or decreases in productivity. As a result, our restructuring plans could have an adverse impact on our financial condition or results of operations.

We have significantly fewer financial resources than most of our competitors, which limits our ability to implement new products or enhancements to our current products and may require us to implement additional future restructuring plans, which in turn could adversely affect our future sales and financial condition.

Financial resource constraints could limit our ability to execute our product strategy or require us to implement additional restructuring plans, particularly if we are unable to generate sufficient cash from operations or obtain additional sources of financing. Any future restructuring actions may slow our development of new or enhanced products by limiting our research and development and engineering activities. Our cash balances are also lower than those of our competitors, which may limit our ability to develop competitive new products on a timely basis or at all. If we are unable to successfully introduce new or enhanced products, our sales, operating results and financial condition will be adversely affected.

If we are not profitable in the future, we may be unable to continue our operations.

We have incurred operating losses each fiscal year since 2010 and have an accumulated deficit of $435.0 million as of December 31, 2021. If and when we achieve profitability depends upon a number of factors, including our ability to develop and market innovative products, accurately estimate inventory needs, contract effectively for manufacturing capacity and maintain sufficient funds to finance our activities. We cannot assure our investors that we will ever achieve annual profitability, or that we will be able to maintain profitability if achieved. If we are not profitable in the future, we may be unable to continue our operations.

A significant amount of our revenue comes from a limited number of customers and distributors and from time to time we may enter into exclusive deals with customers, exposing us to increased credit risk and subjecting our cash flow to the risk that any of our customers or distributors could decrease or cancel its orders.

The display manufacturing market is highly concentrated and we are, and will continue to be, dependent on a limited number of customers and distributors for a substantial portion of our revenue. Sales to our top distributor represented 27% and 7% of revenue for the years ended December 31, 2021 and 2020, respectively. If any of our distributors ceases to do business with us, it may be difficult for us to find adequate replacements, and even if we do, it may take some time. The loss of any of our top distributors could negatively affect our results of operations. Additionally, revenue attributable to our top five end customers represented 76% and 58% of revenue for the years ended December 31, 2021 and 2020, respectively. As of December 31, 2021, we had three accounts that each represented 10% or more of accounts receivable. As of December 31, 2020, we had two accounts that each represented 10% or more of accounts receivable. Orders included in our backlog may be fully or partially cancelable. A reduction, delay or cancellation of orders from one or more of our significant customers, or a decision by one or more of our significant customers to select products manufactured by a competitor or to use its own internally-developed semiconductors, would significantly and negatively impact our revenue. Further, the concentration of our accounts receivable with a limited number of customers increases our credit risk. The failure of these customers to pay their balances, or any customer to pay future outstanding balances, would result in an operating expense and reduce our cash flows.

We generally do not have long-term purchase commitments from our customers and if our customers cancel or change their purchase commitments, our revenue and operating results could suffer.

Substantially all of our sales to date have been made on a purchase order basis. We generally do not have long-term commitments with our customers. As a result, our customers may cancel, change or delay product purchase commitments, which could cause our revenue to decline and materially and adversely affect our results of operations.

20

Our revenue and operating results can fluctuate from period to period, which could cause our share price to decline.

Our revenue and operating results have fluctuated in the past and may fluctuate from period to period in the future due to a variety of factors, many of which are beyond our control. Factors that may contribute to these fluctuations include those described in this "Risk Factors" section of this report, such as the timing, changes in or cancellation of orders by customers, market acceptance of our products and our customers’ products and the timing and extent of product development costs. Additionally, our business is subject to seasonality related to the markets we serve and the location of our customers. For example, we have historically experienced higher revenue from the digital projector market in the third quarter of the year, and lower revenue in the first quarter of the year. As a result of these and other factors, the results of any prior quarterly or annual periods should not be relied upon as indications of our future revenue or operating performance. Fluctuations in our revenue and operating results could cause our share price to decline.

If we are unable to generate sufficient cash from operations and are forced to seek additional financing alternatives, or in the event we acquire or make an investment in companies that complement our business, our working capital may be adversely affected and our shareholders may experience dilution or our operations may be impaired.

We may be unable to generate or sustain positive cash flow from operating activities and would then be required to use existing cash and cash equivalents to support our working capital and other cash requirements. Additionally, from time to time, we may evaluate acquisitions of, or investments in, businesses, products or technologies that complement our business. Any transactions, if consummated, may consume a material portion of our working capital or require the issuance of equity securities that may result in dilution to existing shareholders. If additional funds are required to support our working capital requirements, acquisitions or other purposes, we may seek to raise funds through debt and equity financing or from other sources. If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our shareholders could be significantly diluted, and these newly-issued securities may have rights, preferences or privileges senior to those of existing shareholders. If we raise additional funds by obtaining loans from third parties, the terms of those financing arrangements may include negative covenants or other restrictions on our business that could impair our operating flexibility, and would also require us to incur interest expense. We can provide no assurance that additional financing will be available at all or, if available, that we would be able to obtain additional financing on terms favorable to us.

We license our intellectual property, which exposes us to risks of infringement or misappropriation, and may cause fluctuations in our operating results.

We have licensed certain intellectual property to third parties and may enter into additional license arrangements in the future. We cannot assure you, however, that others will be interested in licensing our intellectual property on commercially favorable terms or at all. We also cannot ensure that licensees will honor agreed-upon market restrictions, not infringe upon or misappropriate our intellectual property or maintain the confidentiality of our proprietary information.

IP license agreements are complex and earning and recognizing revenue under these agreements depends upon many factors, including completion of milestones, allocation of values to delivered items and customer acceptances. Many of these factors require significant judgments. Also, generating revenue from these arrangements is a lengthy and complex process that may last beyond the period in which efforts begin and, once an agreement is in place, the timing of revenue recognition may depend on events such as customer acceptance of deliverables, achievement of milestones, our ability to track and report progress on contracts, customer commercialization of the licensed technology and other factors, any or all of which may or may not be achieved. The accounting rules associated with recognizing revenue from these transactions are complex and subject to interpretation. Due to these factors, the amount of licensing revenue recognized in any period, if any, and our results of operations, may differ significantly from our expectations.

Finally, because licensing revenue typically has a higher margin compared to product sales, licensing revenue can have a disproportionate impact on our gross profit and results of operations. There is no assurance that we will be able to maintain a consistent level of licensing revenue or mix of licensing revenue and revenue from product sales, which could result in wide fluctuations in our results of operations from period to period, making it difficult to accurately measure the performance of our business.

Our net operating loss carryforwards may be limited or they may expire before utilization.

As of December 31, 2021, we had federal, state and foreign net operating loss carryforwards of approximately $166.4 million, $6.8 million, and $39.5 million respectively, which will begin to expire in 2022. These net operating loss carryforwards may be used to offset future taxable income and thereby reduce our income taxes otherwise payable. However, we cannot assure you that we will have taxable income in the future before all or a portion of these net operating loss carryforwards expire.

21

Additionally, our federal net operating losses may be limited by Section 382 of the Internal Revenue Code of 1986, as amended (the "Code"), which imposes an annual limit on the ability of a corporation that undergoes an "ownership change" to use its net operating loss carryforwards to reduce its tax liability. An ownership change is generally defined as a greater than 50% increase in equity ownership by 5% shareholders in any three-year period. In the event of certain changes in our shareholder base, we may at some time in the future experience an "ownership change" and the use of our federal net operating loss carryforwards may be limited. In addition, the Tax Cuts and Jobs Act (the "TCJA"), limits the deduction for net operating loss carryforwards to 80 percent of taxable income for losses arising in taxable years beginning after December 31, 2020.

We face a number of risks as a result of the concentration of our operations and customers in Asia.

Many of our customers are located in Japan, China, or Taiwan. Sales outside the U.S. accounted for approximately 97% and 93% of revenue for the years ended December 31, 2021 and 2020, respectively. We anticipate that sales outside the U.S. will continue to account for a substantial portion of our revenue in future periods. In addition, customers who incorporate our products into their products sell a substantial portion of their products outside of the U.S. All of our products are also manufactured outside of the U.S. and most of our current manufacturers are located in Taiwan. Furthermore, most of our employees are located in China, Japan and Taiwan. Our Asian operations require significant management attention and resources, and we are subject to many risks associated with operations in Asia, including, but not limited to:

•outbreaks of health epidemics in China or other parts of Asia, including COVID-19;

•difficulties in managing international distributors and manufacturers due to varying time zones, languages and business customs;

•compliance with U.S. laws affecting operations outside of the U.S., such as the Foreign Corrupt Practices Act;

•reduced or limited protection of our IP, particularly in software, which is more prone to design piracy;

•difficulties in collecting outstanding accounts receivable balances;

•changes in tax rates, tax laws and the interpretation of those laws;

•difficulties regarding timing and availability of export and import licenses;

•ensuring that we obtain complete and accurate information from our Asian operations to make proper disclosures in the United States;

•political and economic instability;

•difficulties in maintaining sales representatives outside of the U.S. that are knowledgeable about our industry and products;

•changes in the regulatory environment in China, Japan and Taiwan that may significantly impact purchases of our products by our customers or our customers’ sales of their own products;

•imposition of new tariffs, quotas, trade barriers and similar trade restrictions on our sales;

•varying employment and labor laws; and

•greater vulnerability to infrastructure and labor disruptions than in established markets.

Any of these factors could require a disproportionate share of management’s attention, result in increased costs or decreased revenues, and could materially affect our product sales, financial condition and results of operations.

Our operations in Asia expose us to heightened risks due to natural disasters.

The risk of natural disasters in the Pacific Rim region is significant. Natural disasters in countries where our manufacturers or customers are located could result in disruption of our manufacturers’ and customers’ operations, resulting in significant delays in shipment of, or significant reductions in orders for, our products. There can be no assurance that we can locate additional manufacturing capacity or markets on favorable terms, or find new customers, in a timely manner, if at all. Natural disasters in this region could also result in:

•reduced end user demand due to the economic impact of any natural disaster;

•a disruption to the global supply chain for products manufactured in areas affected by natural disasters that are included in products purchased either by us or by our customers;

•an increase in the cost of products that we purchase due to reduced supply; and

•other unforeseen impacts as a result of the uncertainty resulting from a natural disaster.

22

We face additional risks associated with our operations in China and our results of operations and financial position may be harmed by changes in China's political, economic or social conditions or changes in U.S.-China relations.

We have, and expect to continue to have, significant operations in China. The economy of China differs from the economies of many countries in important respects such as structure, government involvement, level of development, growth rate, capital reinvestment, allocation of resources, self-sufficiency, rate of inflation, foreign currency flows and balance of payments position, among others. There can be no assurance that China’s economic policies will be consistent or effective and our results of operations and financial position may be harmed by changes in China’s political, economic or social conditions. Additionally, the political and economic relationship between the U.S. and China is uncertain, and any changes in policy as a result may adversely affect our business. For example, if China were to take action against the United States in response to actual or perceived political or economic threats or changes in policy, such as the detainment of Americans traveling on business, our operations could be adversely affected.

Additionally, our Chinese subsidiary is considered a foreign-invested enterprise and is subject to laws and regulations applicable to foreign investment in China and, in particular, laws applicable to foreign-invested enterprises. For example, China's government imposes control over the convertibility of RMB into foreign currencies, which can cause difficulties converting cash held in RMB to other currencies. While the overall effect of legislation over the past two decades has significantly enhanced the protections afforded to various foreign investments in China, China has not developed a fully integrated legal system, and recently enacted laws and regulations may not sufficiently cover all aspects of economic activities in China. Because these laws and regulations are relatively new, and published court decisions are limited and nonbinding in nature, the interpretation and enforcement of these laws and regulations involve uncertainties. In addition, China's legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all, which may have a retroactive effect. As a result, we may not be aware of our violation of these policies and rules until after the violation occurs. Any administrative and court proceedings in China may be protracted, resulting in substantial costs and diversion of resources and management attention. Further, since Chinese administrative and court authorities have significant discretion in interpreting and implementing statutory and contractual terms, it may be more difficult to evaluate the outcome of administrative and court proceedings. These uncertainties may also impede our ability to enforce the contracts entered into by our Chinese subsidiary and could materially and adversely affect our business and results of operations. 

Our international operations expose us to risks resulting from the fluctuations of foreign currencies.

We are exposed to risks resulting from the fluctuations of foreign currencies, primarily those of Japan, Taiwan, China and Canada. We sell our products to OEMs that incorporate our products into other products that they sell outside of the U.S. While sales of our products to OEMs are denominated in U.S. dollars, the products sold by OEMs are denominated in foreign currencies. Accordingly, any strengthening of the U.S. dollar against these foreign currencies will increase the foreign currency price equivalent of our products, which could lead to a change in the competitive nature of these products in the marketplace. This, in turn, could lead to a reduction in revenue.

In addition, a portion of our operating expenses, such as employee salaries and foreign income taxes, are denominated in foreign currencies. Accordingly, our operating results are affected by changes in the exchange rate between the U.S. dollar and those currencies. Any future strengthening of those currencies against the U.S. dollar will negatively impact our operating results by increasing our operating expenses as measured in U.S. dollars.

We may engage in financial hedging techniques in the future as part of a strategy to address potential foreign currency exchange rate fluctuations. These hedging techniques, however, may not be successful at reducing our exposure to foreign currency exchange rate fluctuations and may increase costs and administrative complexity.

23

Failure to comply with anti-bribery, anti-corruption, and anti-money laundering laws could subject us to penalties and other adverse consequences.

We are subject to the Foreign Corrupt Practices Act ("FCPA") and other anti-corruption, anti-bribery and anti-money laundering laws in various jurisdictions. From time to time, we may leverage third parties to help conduct our businesses abroad. We and our third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities and may be held liable for the corrupt or other illegal activities of these third-party business partners and intermediaries, our employees, representatives, contractors, channel partners, and agents, even if we do not explicitly authorize such activities. While we have policies and procedures to address compliance with such laws, we cannot assure you that all of our employees and agents will not take actions in violation of our policies and applicable law, for which we may be ultimately held responsible. Any violation of the FCPA or other applicable anti-bribery, anti-corruption laws, and anti-money laundering laws could result in whistleblower complaints, adverse media coverage, investigations, loss of export privileges, severe criminal or civil sanctions, or suspension or debarment from U.S. government contracts, all of which may have an adverse effect on our reputation, our business, results of operations and financial condition.

Our reported financial results may be materially and adversely affected by changes in accounting principles generally accepted in the United States.

Generally accepted accounting principles in the United Sates are subject to interpretation by the Financial Accounting Standards Board ("FASB"), the SEC, and various bodies formed to promulgate and interpret appropriate accounting principles. A change in these principles or interpretations could have a significant effect on our reported financial results and could materially and adversely affect the transactions completed before the announcement of a change. Additionally, the adoption of new or revised accounting principles may require that we make significant changes to our systems, processes and controls.

If we are unable to maintain effective disclosure controls and internal controls over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports, and the market price of our common stock may be materially and adversely affected.

If we are unable to maintain effective disclosure controls and internal controls over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports. For example, in the second quarter of 2019, we identified a material weakness in our internal controls over financial reporting related to the review of aged liabilities for possible extinguishment due to the expiration of the statute of limitation, which was remediated as of December 31, 2019. Additionally, if any new internal control procedures which may be adopted or our existing internal control procedures are deemed inadequate, or if we identify additional material weaknesses in our disclosure controls or internal controls over financial reporting in the future, we will be unable to assert that our internal controls are effective. If we are unable to do so, or if our auditors are unable to attest to the effectiveness of our internal controls, we could lose investor confidence in the accuracy and completeness of our financial reports, which would cause the price of our common stock to decline.

As we have limited insurance coverage, any incurred liability resulting from uncovered claims could adversely affect our financial condition and results of operations.

Our insurance policies may not be adequate to fully offset losses from covered incidents, and we do not have coverage for certain losses. For example, we do not have earthquake insurance related to our Asian operations because adequate coverage is not offered at economically justifiable rates. If our insurance coverage is inadequate to protect us against catastrophic losses, any uncovered losses could adversely affect our financial condition and results of operations.

Our dependence on selling to distributors and integrators increases the complexity of managing our supply chain and may result in excess inventory or inventory shortages.

Selling to distributors and OEMs that build display devices based on specifications provided by branded suppliers, also referred to as integrators, reduces our ability to forecast sales accurately and increases the complexity of our business. Our sales are generally made on the basis of customer purchase orders rather than long-term purchase commitments. Our distributors, integrators and customers may cancel or defer purchase orders at any time, but we must order wafer inventory from our contract manufacturers three to four months in advance.

24

The estimates we use for our advance orders from contract manufacturers are based, in part, on reports of inventory levels and production forecasts from our distributors and integrators, which act as intermediaries between us and the companies using our products. This process requires us to make numerous assumptions concerning demand and to rely on the accuracy of the reports and forecasts of our distributors and integrators, each of which may introduce error into our estimates of inventory requirements. Our failure to manage this challenge could result in excess inventory or inventory shortages that could materially impact our operating results or limit the ability of companies using our semiconductors to deliver their products. If we overestimate demand for our products, it could lead to significant charges for obsolete inventory. On the other hand, if we underestimate demand, we could forego revenue opportunities, lose market share and damage our customer relationships.

We may be unable to successfully manage any future growth, including the integration of any acquisition or equity investment, which could disrupt our business and severely harm our financial condition.

If we fail to effectively manage any future internal growth, our operating expenses may increase more rapidly than our revenue, adversely affecting our financial condition and results of operations. To manage any future growth effectively in a rapidly evolving market, we must be able to maintain and improve our operational and financial systems, train and manage our employee base and attract and retain qualified personnel with relevant experience. We could spend substantial amounts of time and money in connection with expansion efforts for which we may not realize any profit. Our systems, procedures, controls or financial resources may not be adequate to support our operations and we may not be able to grow quickly enough to exploit potential market opportunities. In addition, we may not be able to successfully integrate the businesses, products, technologies or personnel of any entity that we might acquire in the future, or we may fail to realize the anticipated benefits of any such acquisition. The successful integration of any acquired business as well as the retention of personnel may require significant attention from our management and could divert resources from our existing business, which in turn could have an adverse effect on our business operations. Acquired assets or businesses may not achieve the anticipated benefits we expect due to a number of factors including: unanticipated costs or liabilities associated with such acquisition, including in the case of acquisitions we may make outside of the United States, difficulty in operating in foreign countries or complying with foreign regulatory requirements, incurrence of acquisition-related costs, harm to our relationships with existing customers as a result of such acquisition, harm to our brand and reputation, the loss of key employees in the acquired businesses, use of resources that are needed in other parts of our business, and use of substantial portions of our available cash to consummate any such acquisition. Any failure to successfully integrate any entity we may acquire or any failure to achieve the anticipated benefits of any such acquisition could disrupt our business and seriously harm our financial condition.

Continued compliance with regulatory and accounting requirements will be challenging and will require significant resources.

We spend a significant amount of management time and external resources to comply with changing laws, regulations and standards relating to corporate governance and public disclosure, including evolving SEC rules and regulations, Nasdaq Global Market rules, the Dodd-Frank Wall Street Reform and Consumer Protection Act and the Sarbanes-Oxley Act of 2002, which requires management’s annual review and evaluation of internal control over financial reporting. Failure to comply with these laws and rules could lead to investigation by regulatory authorities, de-listing from the Nasdaq Global Market, or penalties imposed on us.

25

Regulations related to conflict minerals may adversely impact our business.

The SEC has adopted disclosure and reporting rules intended to improve transparency and accountability concerning the supply of certain minerals, known as conflict minerals, originating from the Democratic Republic of Congo ("DRC") and adjoining countries. These rules require us to conduct a reasonable inquiry to determine the origin of certain materials used in our products and disclose whether our products use any materials containing conflict minerals originating from the DRC and adjoining countries. Since we do not own or operate a semiconductor fabrication facility and do not manufacture our products internally, we are dependent on the information provided by third-party foundries and production facilities regarding the materials used and the supply chains for the materials. Further, there are costs associated with complying with these rules, including costs incurred to conduct inquiries to determine the sources of any materials containing conflict minerals used in our products, to fulfill our reporting requirements and to develop and implement potential changes to products, processes or sources of supply if it is determined that our products contain or use any conflict minerals from the DRC or adjoining countries. The implementation of these rules could also affect the sourcing, supply and pricing of materials used in our products. For example, there may only be a limited number of suppliers offering “conflict free” materials and we cannot be sure that we will be able to obtain necessary "conflict free" materials from such suppliers in sufficient quantities or at reasonable prices. In addition, we may face reputational challenges if we determine that any of our products contain minerals that are not conflict free or if we are unable to sufficiently verify the origins for all materials containing conflict minerals used in our products through the procedures we may implement.

Our effective income tax rate is subject to unanticipated changes in, or different interpretations of, tax rules and regulations, and forecasting our effective income tax rate is complex and subject to uncertainty.

As a global company, we are subject to taxation by a number of taxing authorities and as such, our tax rates vary among the jurisdictions in which we operate. Unanticipated changes in our tax rates could affect our future results of operations. Our effective tax rates could be adversely affected by changes in the mix of earnings in countries with differing statutory tax rates, changes in tax laws or the interpretation of tax laws either in the U.S. or abroad, or by changes in the valuation of our deferred tax assets and liabilities. The ultimate outcomes of any future tax audits are uncertain, and we can give no assurance as to whether an adverse result from one or more of them would have a material effect on our operating results and financial position.

The computation of income tax expense is complex as it is based on the laws of numerous tax jurisdictions and requires significant judgment on the application of complicated rules governing accounting for tax provisions under U.S. generally accepted accounting principles. Income tax expense for interim quarters is based on our forecasted tax rate for the year, which includes forward looking financial projections, including the expectations of profit and loss by jurisdiction, and contains numerous assumptions. For these reasons, our tax rate may be materially different than our forecast.

We rely upon certain critical information systems for the operation of our business, and the failure of any critical information system may result in serious harm to our business.

We maintain and rely upon certain critical information systems for the effective operation of our business. These information systems include telecommunications, the Internet, our corporate intranet, various computer hardware and software applications, network communications and e-mail. These information systems are subject to attacks, failures and access denials from a number of potential sources including viruses, destructive or inadequate code, power failures, and physical damage to computers, communication lines and networking equipment. To the extent that these information systems are under our control, we have implemented security procedures, such as virus protection software and firewall monitoring, to address the outlined risks. Security procedures for information systems cannot be guaranteed to be failsafe and our inability to use or access these information systems at critical times could compromise the timely and efficient operation of our business. Additionally, any compromise of our information security could result in the unauthorized publication of our confidential business or proprietary information, cause an interruption in our operations, result in the unauthorized release of customer or employee data, result in a violation of privacy or other laws, or expose us to a risk of litigation or damage our reputation, any or all of which could harm our business and operating results.

26

Environmental laws and regulations may cause us to incur significant expenditures to comply with applicable laws and regulations, and we may be assessed considerable penalties for noncompliance.

We are subject to numerous environmental laws and regulations. Compliance with current or future environmental laws and regulations could require us to incur substantial expenses which could harm our business, financial condition and results of operations. We have worked, and will continue to work, with our suppliers and customers to ensure that our products are compliant with enacted laws and regulations. Failure by us or our contract manufacturers to comply with such legislation could result in customers refusing to purchase our products and could subject us to significant monetary penalties in connection with a violation, either of which would have a material adverse effect on our business, financial condition and results of operations.

Increasing attention on environmental, social and governance (ESG) matters may have a negative impact on our business, impose additional costs on us, and expose us to additional risks.

Companies are facing increasing attention from investors, customers, partners, consumers and other stakeholders relating to ESG matters, including environmental stewardship, social responsibility, diversity and inclusion, racial justice and workplace conduct. In addition, organizations that provide information to investors on corporate governance and related matters have developed ratings processes for evaluating companies on their approach to ESG matters. Such ratings are used by some investors to inform their investment and voting decisions. Unfavorable ESG ratings may lead to negative investor sentiment toward the Company, which could have a negative impact on our stock price and our access to and costs of capital.

We have established corporate social responsibility programs aligned with sound environmental, social and governance principles. These programs reflect our current initiatives and are not guarantees that we will be able to achieve them. Our ability to successfully execute these initiatives and accurately report our progress presents numerous operational, financial, legal, reputational and other risks, many of which are outside our control, and all of which could have a material negative impact on our business. Additionally, the implementation of these initiatives imposes additional costs on us. If our ESG initiatives fail to satisfy investors, customers, partners and our other stakeholders, our reputation, our ability to sell products and services to customers, our ability to attract or retain employees, and our attractiveness as an investment, business partner or acquirer could be negatively impacted. Similarly, our failure or perceived failure to pursue or fulfill our goals, targets and objectives or to satisfy various reporting standards within the timelines we announce, or at all, could also have similar negative impacts and expose us to government enforcement actions and private litigation.

Company Risks Related to the Semiconductor Industry and Our Markets

Dependence on a limited number of sole-source, third-party manufacturers for our products exposes us to possible shortages based on low manufacturing yield, errors in manufacturing, uncontrollable lead-times for manufacturing, capacity allocation, price increases with little notice, volatile inventory levels and delays in product delivery, any of which could result in delays in satisfying customer demand, increased costs and loss of revenue.

We do not own or operate a semiconductor fabrication facility and do not have the resources to manufacture our products internally. We rely on a limited number of foundries and assembly and test vendors to produce all of our wafers and for completion of finished products. Our wafers are not fabricated at more than one foundry at any given time and our wafers typically are designed to be fabricated in a specific process at only one foundry. Sole sourcing each product increases our dependence on our suppliers. We have limited control over delivery schedules, quality assurance, manufacturing yields, potential errors in manufacturing and production costs. We do not have long-term supply contracts with our third-party manufacturers, so they are not obligated to supply us with products for any specific period of time, quantity or price, except as may be provided in a particular purchase order. Our suppliers can increase the prices of the products we purchase from them with little notice, which may cause us to increase the prices to our customers and harm our competitiveness. Because our requirements represent only a small portion of the total production capacity of our contract manufacturers, they could reallocate capacity to other customers during periods of high demand for our products, as they have done in the past. We expect this may occur again in the future.

27

Establishing a relationship with a new contract manufacturer in the event of delays or increased prices would be costly and burdensome. The lead time to make such a change would be at least nine months, and the estimated time for us to adapt a product’s design to a particular contract manufacturer’s process is at least four months. Additionally, we have chosen, and may continue to choose new foundries to manufacture our wafers which in turn, may require us to modify our design methodology flow for the process technology and intellectual property cores of the new foundry. If we have to qualify a new foundry or packaging, assembly and testing supplier for any of our products or if we are unable to obtain our products from our contract manufacturers on schedule, at costs that are acceptable to us, or at all, we could incur significant delays in shipping products, our ability to satisfy customer demand could be harmed, our revenue from the sale of products may be lost or delayed and our customer relationships and ability to obtain future design wins could be damaged.

Shortages of materials used in the manufacturing of our products and other key components of our customers’ products may increase our costs, impair our ability to ship our products on time and delay our ability to sell our products.

We are currently facing shortages of components and materials that are critical to the manufacture of our products and our customers’ products. Such critical components and materials may include semiconductor wafers and packages, double data rate memory die, display components, analog-to-digital converters, digital receivers, video decoders and voltage regulators. These shortages are resulting in additional costs to us and we may be unable to ship our products to our customers in a timely fashion, both of these factors could harm our business and adversely affect our results of operations.

Our highly integrated products and high-speed mixed signal products are difficult to manufacture without defects and the existence of defects could result in increased costs, delays in the availability of our products, reduced sales of products or claims against us.

The manufacture of semiconductors is a complex process and it is often difficult for semiconductor foundries to produce semiconductors free of defects. Because many of our products are more highly integrated than other semiconductors and incorporate mixed signal analog and digital signal processing, multi-chip modules and embedded memory technology, they are even more difficult to produce without defects. Defective products can be caused by design or manufacturing difficulties. Identifying quality problems can be performed only by analyzing and testing our semiconductors in a system after they have been manufactured. The difficulty in identifying defects is compounded because the process technology is unique to each of the multiple semiconductor foundries we contract with to manufacture our products. Despite testing by both our customers and us, errors or performance problems may be found in existing or new semiconductors. Failure to achieve defect-free products may result in increased costs and delays in the availability of our products. Defects may also divert the attention of our engineering personnel from our product development efforts to find and correct the issue, which would delay our product development efforts.

Additionally, customers could seek damages from us for their losses, and shipments of defective products may harm our reputation with our customers. If a product liability claim is brought against us, the cost of defending the claim could be significant and would divert the efforts of our technical and management personnel and harm our business. Further, our business liability insurance may be inadequate or future coverage may be unavailable on acceptable terms, which could adversely impact our financial results.

We experience a small number of semiconductor field failures infrequently in certain customer applications that required us to institute additional testing. As a result of these field failures, we have incurred warranty costs due to customers returning potentially affected products and have experienced reductions in revenues due to delays in production. Our customers have also experienced delays in receiving product shipments from us that resulted in the loss of revenue and profits. Additionally, shipments of defective products could cause us to lose customers or to incur significant replacement costs, either of which would harm our reputation and our business. Any defects, errors or bugs could also interrupt or delay sales of our new products to our customers, which would adversely affect our financial results.

28

The development of new products is extremely complex and we may be unable to develop our new products in a timely manner, which could result in a failure to obtain new design wins and/or maintain our current revenue levels.

In addition to the inherent difficulty of designing complex integrated circuits, product development delays may result from:

•difficulties in hiring and retaining necessary technical personnel;

•difficulties in reallocating engineering resources and overcoming resource limitations;

•difficulties with contract manufacturers;

•changes to product specifications and customer requirements;

•changes to market or competitive product requirements; and

•unanticipated engineering complexities.

If we are not successful in the timely development of new products, we may fail to obtain new design wins and our financial results will be adversely affected.

Intense competition in our markets may reduce sales of our products, reduce our market share, decrease our gross profit and result in large losses.

We compete with specialized and diversified electronics and semiconductor companies that offer display processors or scaling components including: Actions Microelectronics Co., Ltd., ARM Holdings PLC, Dolby Laboratories, Inc., Egis Technology Inc., Hisilicon Technologies Co., Ltd., i-Chips Technology Inc., Lattice Semiconductor Corporation, MediaTek Inc., Novatek Microelectronics Corp., NVIDIA Corporation, Qualcomm Incorporated, Realtek Semiconductor Corp., Renesas Electronics America Inc., Socionext Inc., Solomon Systech (International) Ltd., STMicroelectronics N.V., Sunplus Technology Co., Ltd., Synaptics Incorporated, Texas Instruments Incorporated, Unisoc Communications, Inc., and other companies. Potential and current competitors may include diversified semiconductor manufacturers and the semiconductor divisions or affiliates of some of our customers, including: Apple Inc., Broadcom Inc., LG Electronics, Inc., MegaChips Corporation, Mitsubishi Digital Electronics America, Inc., NEC Corporation, Panasonic Corporation, Samsung Electronics Co., Ltd., Socionext Inc., ON Semiconductor Corporation, Seiko Epson Corporation, Sharp Electronics Corporation, Sony Corporation, and Toshiba America, Inc. In addition, start-up companies may seek to compete in our markets.

Many of our competitors have longer operating histories and greater resources to support development and marketing efforts than we do. Some of our competitors operate their own fabrication facilities. These competitors may be able to react more quickly and devote more resources to efforts that compete directly with our own. Additionally, any consolidation in the semiconductor industry may impact our competitive position. Our current or potential customers have developed, and may continue to develop, their own proprietary technologies and become our competitors. Increased competition from both competitors and our customers’ internal development efforts could harm our business, financial condition and results of operations by, for example, increasing pressure on our profit margin or causing us to lose sales opportunities. For example, frame rate conversion technology similar to that used in our line of MotionEngine® advanced video co-processors continues to be integrated into the SoC and display timing controller products of our competitors. We cannot assure you that we can compete successfully against current or potential competitors.

If we are not able to respond to the rapid technological changes and evolving industry standards in the markets in which we compete, or seek to compete, our products may become less desirable or obsolete.

The markets in which we compete or seek to compete are subject to rapid technological change and miniaturization capabilities, frequent new product introductions, changing customer requirements for new products and features and evolving industry standards. The introduction of new technologies and emergence of new industry standards could render our products less desirable or obsolete, which could harm our business and significantly decrease our revenue. Examples of changing industry standards include the growing use of broadband to deliver video content, increased display resolution and size, faster screen refresh rates, video capability such as High Dynamic Range, the proliferation of new display devices and the drive to network display devices together. Our failure to predict market needs accurately or to timely develop new competitively priced products or product enhancements that incorporate new industry standards and technologies, including integrated circuits with increasing levels of integration and new features, using smaller geometry process technologies, may harm market acceptance and sales of our products.

29

Our products are incorporated into our customers’ products, which have different parts and specifications and utilize multiple protocols that allow them to be compatible with specific computers, video standards and other devices. If our customers’ products are not compatible with these protocols and standards, consumers will return, or not purchase these products and the markets for our customers’ products could be significantly reduced. Additionally, if the technology used by our customers becomes less competitive due to cost, customer preferences or other factors relative to alternative technologies, sales of our products could decline.

We use a customer-owned tooling process for manufacturing most of our products, which exposes us to the possibility of poor yields and unacceptably high product costs.

We build most of our products on a customer-owned tooling basis, whereby we directly contract the manufacture of our products, including wafer production, assembly and testing. As a result, we are subject to increased risks arising from wafer manufacturing yields and risks associated with coordination of the manufacturing, assembly and testing process. Poor product yields result in higher product costs, which could make our products less competitive if we increase our prices to compensate for our higher costs or could result in lower gross profit margins if we do not increase our prices.

We depend on manufacturers of our semiconductor products not only to respond to changes in technology and industry standards but also to continue the manufacturing processes on which we rely.

To respond effectively to changes in technology and industry standards, we depend on our contracted foundries to implement advanced semiconductor technologies and our operations could be adversely affected if those technologies are unavailable, delayed or inefficiently implemented. In order to increase performance and functionality and reduce the size of our products, we are continuously developing new products using advanced technologies that further miniaturize semiconductors and we are dependent on our foundries to develop and provide access to the advanced processes that enable such miniaturization. We cannot be certain that future advanced manufacturing processes will be implemented without difficulties, delays or increased expenses. Our business, financial condition and results of operations could be materially adversely affected if advanced manufacturing processes are unavailable to us, substantially delayed or inefficiently implemented.

Creating the capacity for new technological changes may cause manufacturers to discontinue older manufacturing processes in favor of newer ones. We must then either retire the affected part or port (develop) a new version of the part that can be manufactured with a newer process technology. In the event that a manufacturing process is discontinued, our current suppliers may be unwilling or unable to manufacture our current products. We may not be able to place last time buy orders for the old technology or find alternate manufacturers of our products to allow us to continue to produce products with the older technology while we expend the significant costs for research and development and time to migrate to new, more advanced processes.

Because of our long product development process and sales cycles, we may incur substantial costs before we earn associated revenue and ultimately may not sell as many units of our products as we originally anticipated.

We develop products based on anticipated market and customer requirements and incur substantial product development expenditures, which can include the payment of large up-front, third-party license fees and royalties, prior to generating the associated revenue. Our work under these projects is technically challenging and places considerable demands on our limited resources, particularly on our most senior engineering talent. Additionally, the transition to smaller geometry process technologies continues to significantly increase the cost and complexity of new product development, particularly with regards to tooling, software tools, third party IP and engineering resources. Because the development of our products incorporates not only our complex and evolving technology, but also our customers’ specific requirements, a lengthy sales process is often required before potential customers begin the technical evaluation of our products. Our customers typically perform numerous tests and extensively evaluate our products before incorporating them into their systems. The time required for testing, evaluation and design of our products into a customer’s system can take nine months or more. It can take an additional nine months or longer before a customer commences volume shipments of systems that incorporate our products, if at all. Because of the lengthy development and sales cycles, we will experience delays between the time we incur expenditures for research and development, sales and marketing and inventory and the time we generate revenue, if any, from these expenditures.

Furthermore, we have entered into and may in the future enter into, co-development agreements that do not guarantee future sales volumes and limit our ability to sell the developed products to other customers. The exclusive nature of these development agreements increases our dependence on individual customers, particularly since we are limited in the number of products we are able to develop at any one time.

30

If actual sales volumes for a particular product are substantially less than originally anticipated, we may experience large write-offs of capitalized license fees, software development tools, product masks, inventories or other capitalized or deferred product-related costs, any of which would negatively affect our operating results.

Our developed software may be incompatible with industry standards and challenging and costly to implement, which could slow product development or cause us to lose customers and design wins.

We provide our customers with software development tools and with software that provides basic functionality for our integrated circuits and enables enhanced connectivity of our customers’ products. Software development is a complex process and we are dependent on software development languages and operating systems from vendors that may limit our ability to design software in a timely manner. Also, as software tools and interfaces change rapidly, new software languages introduced to the market may be incompatible with our existing systems and tools, requiring significant engineering efforts to migrate our existing systems in order to be compatible with those new languages. Software development disruptions could slow our product development or cause us to lose customers and design wins. The integration of software with our products adds complexity, may extend our internal development programs and could impact our customers’ development schedules. This complexity requires increased coordination between hardware and software development schedules and increases our operating expenses without a corresponding increase in product revenue. This additional level of complexity lengthens the sales cycle and may result in customers selecting competitive products requiring less software integration.

The competitiveness and viability of our products could be harmed if necessary licenses of third-party technology are not available to us on terms that are acceptable to us or at all.

We license technology from independent third parties that is incorporated into our products or product enhancements. Future products or product enhancements may require additional third-party licenses that may not be available to us on terms that are acceptable to us or at all. In addition, in the event of a change in control of one of our licensors, it may become difficult to maintain access to its licensed technology. If we are unable to obtain or maintain any third-party license required to develop new products and product enhancements, we may have to obtain substitute technology with lower quality or performance standards, or at greater cost, either of which could seriously harm the competitiveness of our products.

Our limited ability to protect our IP and proprietary rights could harm our competitive position by allowing our competitors to access our proprietary technology and to introduce similar products.

Our ability to compete effectively with other companies depends, in part, on our ability to maintain the proprietary nature of our technology, including our semiconductor designs and software code. We provide the computer programming code for our software to customers in connection with their product development efforts, thereby increasing the risk that customers will misappropriate our proprietary software. We rely on a combination of patent, copyright, trademark and trade secret laws, as well as nondisclosure agreements and other methods, to help protect our proprietary technologies. As of December 31, 2021, we held 335 patents and had 9 patent applications pending for protection of our significant technologies. Competitors in both the U.S. and foreign countries, many of whom have substantially greater resources than we do, may apply for and obtain patents that will prevent, limit or interfere with our ability to make and sell our products, or they may develop similar technology independently or design around our patents. Effective patent, copyright, trademark and trade secret protection may be unavailable or limited in foreign countries and, thus, make the possibility of piracy of our technology and products more likely in these countries.

We cannot assure you that the degree of protection offered by patent or trade secret laws will be sufficient. Furthermore, we cannot assure you that any patents will be issued as a result of any pending applications or that any claims allowed under issued patents will be sufficiently broad to protect our technology. We may incur significant costs to stop others from infringing our patents. In addition, it is possible that existing or future patents may be invalidated, diluted, circumvented, challenged or licensed to others.

31

Others may bring infringement or indemnification actions against us that could be time-consuming and expensive to defend.

We may become subject to claims involving patents or other intellectual property rights. In recent years, there has been significant litigation in the U.S. and in other jurisdictions involving patents and other intellectual property rights. This litigation is particularly prevalent in the semiconductor industry, in which a number of companies aggressively use their patent portfolios to bring infringement claims. In recent years, there has been an increase in the filing of so-called "nuisance suits," alleging infringement of intellectual property rights. These claims may be asserted initially or as counterclaims in response to claims made by a company alleging infringement of intellectual property rights. These suits pressure defendants into entering settlement arrangements to quickly dispose of such suits, regardless of merit. We may also face claims brought by companies that are organized solely to hold and enforce patents. In addition, we may be required to indemnify our customers against IP claims related to their usage of our products as certain of our agreements include indemnification provisions from third parties relating to our intellectual property.

IP claims could subject us to significant liability for damages and invalidate our proprietary rights. Responding to such claims, regardless of their merit, can be time-consuming, result in costly litigation, divert management’s attention and resources and cause us to incur significant expenses. As each claim is evaluated, we may consider the desirability of entering into settlement or licensing agreements. No assurance can be given that settlements will occur or that licenses can be obtained on acceptable terms or that litigation will not occur. In the event there is a temporary or permanent injunction entered prohibiting us from marketing or selling certain of our products, or a successful claim of infringement against us requiring us to pay damages or royalties to a third-party and we fail to develop or license a substitute technology, our business, results of operations or financial condition could be materially adversely affected. Any IP litigation or claims also could force us to do one or more of the following:

•stop selling products using technology that contains the allegedly infringing IP;

•attempt to obtain a license to the relevant IP, which may not be available on terms that are acceptable to us or at all;

•attempt to redesign those products that contain the allegedly infringing IP; or

•pay damages for past infringement claims that are determined to be valid or which are arrived at in settlement of such litigation or threatened litigation.

If we are forced to take any of the foregoing actions, we may incur significant additional costs or be unable to manufacture and sell our products, which could seriously harm our business. In addition, we may not be able to develop, license or acquire non-infringing technology under reasonable terms. These developments could result in an inability to compete for customers or otherwise adversely affect our results of operations.

Our products are characterized by average selling prices that can decline over relatively short periods of time, which will negatively affect our financial results unless we are able to reduce our product costs or introduce new products with higher average selling prices.

Average selling prices for our products can decline over relatively short periods of time, while many of our product costs are relatively fixed. When our average selling prices decline, our gross profit declines unless we are able to sell more units or reduce the cost to manufacture our products. We have experienced declines in our average selling prices and expect that we will continue to experience them in the future, although we cannot predict when they may occur or how severe they will be. Our financial results will suffer if we are unable to offset any reductions in our average selling prices by increasing our sales volumes, reducing our costs, adding new features to our existing products or developing new or enhanced products in a timely manner with higher selling prices or gross profits.

The cyclical nature of the semiconductor industry may lead to significant variances in the demand for our products and could harm our operations.

In the past, the semiconductor industry has been characterized by significant downturns and wide fluctuations in supply and demand. Also, the industry has experienced significant fluctuations in anticipation of changes in general economic conditions, including economic conditions in Asia, Europe and North America. The cyclical nature of the semiconductor industry has also led to significant variances in product demand and production capacity. We have experienced, and may continue to experience, periodic fluctuations in our financial results because of changes in industry-wide conditions.

Risks Related to Our Strategic Plan and STAR Market Listing

If we are unable to implement our strategy to expand our PRC operations, including the positioning of our subsidiary to qualify and seek an initial public offering on the STAR Market, our ability to access capital, customers, and talent in China could suffer, which in turn may materially and adversely affect our worldwide growth and revenue potential.

In August 2021 we announced our strategic plan to transform our existing subsidiary, Pixelworks Semiconductor Technology (Shanghai) Co., Ltd (“PWSH”) into a profit center for our mobile, projector, and video delivery businesses to improve our access to capital, customers, and talent in China. As part of this strategic plan, we intend to qualify PWSH to file an application for an initial public offering on the Shanghai Stock Exchange’s Science Technology Innovation Board, known as the STAR Market (the “Listing”) to further improve our access to capital markets and to fund growth. We may not be successful in the implementation of our strategic plan, and we may not be able to complete the Listing for a number of reasons, including those related to the risks we face associated with our operations in China as detailed separately above, many of which are outside our control. With respect to the Listing, PWSH must succeed in obtaining PRC governmental approvals required to permit the Listing, and one or more of those approvals may be denied, or significantly delayed, by the PRC regulators for reasons outside our control or unknown to us, or may be conditioned on requirements that we deem would result in an undue burden or material adverse impact on our business. Similarly, the Listing application may be denied or delayed by the Shanghai Stock Exchange in its discretion. Further, the COVID‑19 outbreak, the tensions between the United States and China, or other geopolitical forces, including war, could negatively impact our currently planned projects and investments in the PRC, including the Listing.

Additionally, pursuant to our Capital Increase Agreement, PWSH agreed to attempt to complete all requirements to qualify for a Listing such that the Listing is consummated prior to a certain date (for the private equity and strategic investors ("Investors"), June 30, 2024, and for the employee-owned entities (“ESOP”), December 31, 2024). If PWSH has not consummated the Listing before those dates, or if it seriously violates certain other restructuring actions required by the Capital Increase Agreement such that a Listing by such dates becomes impossible, the respective purchasers may elect to require that PWSH repurchase the purchaser’s respective equity interest for a price equal to the initial purchase price paid by the purchaser plus annual simple interest (for the Investors, at a rate of 3%; for the ESOP, at a rate of 5%). As noted above, various elements in the Listing process are outside our control or may be subject to conditions that are unacceptable to us, and if we fail to obtain the Listing, the provisions of the Capital Increase Agreement would require a use of PWSH cash for purposes not otherwise planned for, which in turn would negatively impact our plans for growth and the cash position of PWSH.

If we are unable to successfully implement our strategic plan, including the Listing, we may not realize the advantages to our PRC operations contemplated by our business strategy, including improving our access to capital markets, customers, and talent in China. Because it may be several years before we know whether the Listing will be completed, we may, in the interim, forego or postpone other alternative actions to strengthen our market position and operations in the PRC.

PRC companies are critical to the global semiconductor industry, and our current business is substantially concentrated in the PRC market. Our inability to build, or any delay in growing, our PRC-based operations over the next several years would materially and adversely limit our operations and operating results, including our revenue growth. In addition, during that time, the process underlying the Listing could result in significant diversion of management time as well as substantial out-of-pocket costs, which could further impair our ability to expand our business.

Even if we complete the Listing, we may not achieve the results contemplated by our business strategy and our strategy for growth in the PRC may not result in increases in the price of our common stock.

We cannot assure you that, even if the Listing is completed, we will realize any or all of our anticipated benefits of the Listing. Our completion of the Listing may not have the anticipated effects of providing access to new capital markets or strengthening our market position and operations in the PRC. If the Listing is completed, PWSH will have broad discretion in the use of the proceeds from the initial sales of shares to PWSH investors, and it may not spend or invest those proceeds in a manner that results in our operating success or with which Pixelworks, Inc. common shareholders agree. Our failure to successfully leverage the completion of the Listing to enhance our access to new capital markets and expand our PRC business could result in a decrease in the price of our common stock, and we cannot assure you that the success of PWSH will have an associated positive effect on the price of our common stock.

33

Completion of the Listing is currently planned for 2023, but there can be no assurances that the Listing will occur in that timeframe, if at all. In the interim, PWSH may require additional funding from Pixelworks to augment its PRC operations, and we cannot give any assurance that such capital will be available from Pixelworks on terms acceptable to us. Any such inability to obtain funds from Pixelworks or other sources may impair the ability of PWSH to grow its operations, which could have a material adverse effect on our consolidated operating results and on the price of our common stock.

PWSH’s status as a publicly traded company that is controlled, but less than wholly owned, by Pixelworks could have an adverse effect on us.

PWSH is not currently a wholly owned subsidiary of Pixelworks, and following the Listing, other holders may hold as much as 20% of the subsidiary. The interests of PWSH may diverge from the interests of Pixelworks and its other subsidiaries in the future. We may face conflicts of interest in managing, financing, or engaging in transactions with PWSH, or allocating business opportunities between our subsidiaries, including future arrangements for operating subsidiaries other than PWSH to license and use our intellectual property.

Pixelworks will retain majority ownership of PWSH after the Listing, but PWSH will be managed by a separate board of directors and officers and those directors and officers will owe fiduciary duties to the various stakeholders of PWSH, including shareholders other than Pixelworks. In the operation of PWSH’s business, there may be situations that arise whereby the directors and officers of PWSH, in the exercise of their fiduciary duties, take actions that may be contrary to the best interests of Pixelworks or its shareholders. Additionally, because PWSH will be managed by a separate board of directors and officers, our organizational structure will become more complex, which may in turn require substantial financial, operational, and management resources.

In the future, PWSH may issue options, restricted shares, and other forms of share-based compensation to its directors, officers, and employees, which could dilute Pixelworks’ ownership in PWSH. In addition, PWSH may engage in capital raising activities in the future that could further dilute Pixelworks’ ownership interest.

The STAR Market is relatively new, and as a result, it is difficult to predict the effect of the proposed Listing, which may in turn negatively affect the price of our common stock on the Nasdaq Global Market.

The China Securities Regulatory Commission, or the CSRC, initially launched the STAR Market in June 2019 and trading on that market began in July 2019. No assurance can be given regarding the effect of the Listing on the market price of PWSH shares or on the price of our common stock on the Nasdaq Global Market. The market price of the PWSH shares and Pixelworks common stock may be volatile or may decline for reasons other than the risk and uncertainties described above, as the result of investor negativity or uncertainty with respect to the proposed Listing.

If the Listing is completed, Pixelworks and PWSH both will be public reporting companies, but each will be subject to separate, and potentially inconsistent, accounting and disclosure requirements, which may lead to investor confusion or uncertainty that could cause decreased demand for, or fluctuations in the price of, one or both of the companies’ publicly traded shares.

If PWSH completes the Listing, it will be subject to accounting, disclosure, and other regulatory requirements of the STAR Market. At the same time, Pixelworks will remain subject to accounting, disclosure, and other regulatory requirements of the SEC and the Nasdaq Global Market. As a result, Pixelworks and PWSH periodically will disclose information simultaneously pursuant to differing laws and regulations. The information disclosed by the two companies will differ, and may differ materially from time to time, due to the distinct, and potentially inconsistent, accounting standards applicable to the two companies and disclosure requirements imposed by securities regulatory authorities, as well as differences in language, culture, and expression habit, in composition of investors in the United States and PRC, and in the capital markets of the United States and the PRC. Differing disclosures could lead to confusion or uncertainty among investors in the publicly traded shares of one or both companies. Differences between the price of PWSH shares on the STAR Market and the price of Pixelworks common stock on Nasdaq Global Market could lead to increased volatility, as some investors seek to arbitrage price differences. Additionally, news about PWSH may affect the price of Pixelworks’ common stock, and vice versa, creating additional uncertainty and volatility.

34

General Risks

The price of our common stock has and may continue to fluctuate substantially.

Our stock price and the stock prices of technology companies similar to Pixelworks have been highly volatile. The price of our common stock may decline and the value of our shareholders' investment may be reduced regardless of our performance.

The daily trading volume of our common stock has historically been relatively low, although, in the three most recent years, trading volume increased compared to historical levels. As a result of the historically low volume, our shareholders may be unable to sell significant quantities of common stock in the public trading markets without a significant reduction in the price of our common shares. Additionally, market fluctuations, as well as general economic and political conditions, including recessions, interest rate changes or international currency fluctuations, may negatively impact the market price of our common stock. Other factors that could negatively impact our stock price include:

•actual or anticipated fluctuations in our operating results;

•changes in or failure to meet expectations as to our future financial performance;

•changes in or failure to meet financial estimates of securities analysts;

•announcements by us or our competitors of technological innovations, design wins, contracts, standards, acquisitions or divestitures;

•the operating and stock price performance of other comparable companies;

•issuances or proposed issuances of equity, debt or other securities by us, or sales of securities by our security holders; and

•changes in market valuations of other technology companies.

Any inability or perceived inability of investors to realize a gain on an investment in our common stock could have an adverse effect on our business, financial condition and results of operations by potentially limiting our ability to retain our customers, to attract and retain qualified employees and to raise capital. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company's securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management's attention and resources.

The interest of our current or potential significant shareholders may conflict with other shareholders and they may attempt to effect changes or acquire control, which could adversely affect our results of operations and financial condition.

Our shareholders may from time to time engage in proxy solicitations, advance shareholder proposals, acquire control or otherwise attempt to effect changes, including by directly voting their shares on shareholder proposals. Campaigns by shareholders to effect changes at publicly traded companies are sometimes led by investors seeking to increase short-term shareholder value through actions such as financial restructuring, increased debt, special dividends, stock repurchases or sales of assets or the entire company. Responding to proxy contests and other actions by activist shareholders can be costly and time-consuming, disrupting our operations and diverting the attention of our Board of Directors and senior management from the pursuit of business strategies. Additionally, uncertainty over our direction and leadership may negatively impact our relationship with our customers and make it more difficult to attract and retain qualified personnel and business partners. As a result, shareholder campaigns could adversely affect our results of operations and financial condition.

35

Future sales of our equity could result in significant dilution to our existing shareholders and depress the market price of our common stock.

It is likely that we will need to seek additional capital in the future and from time to time. If this financing is obtained through the issuance of equity securities, debt convertible into equity securities, options or warrants to acquire equity securities or similar instruments or securities, our existing shareholders will experience dilution in their ownership percentage upon the issuance, conversion or exercise of such securities and such dilution could be significant. For example, in December 2020, we completed a private placement of 3,200,000 shares of common stock to certain accredited investors at a purchase price of $2.071 per share. The issuance and sale of the shares in the private placement had a dilutive impact on our existing stockholders. Additionally, also in December 2020, we completed the sale of 4,900,000 shares of common stock in an underwritten registered offering and an additional 735,000 shares were issued pursuant to the 30-day over-allotment option exercised by the underwriter, at a price to the public of $2.45 per share. Additionally, pursuant to our “at the market” equity offering program, we may sell shares of our common stock having aggregate sales proceeds of up to $25 million from time to time through Cowen and Company, LLC, as our agent. Through December 31, 2021, we sold an aggregate of 1,808,484 shares of our common stock under this at the market offering. The issuance and sale of additional shares of our common stock pursuant to our “at the market” equity offering program or otherwise will have a dilutive impact on our existing stockholders. Additionally, any new equity securities issued by us could have rights, preferences or privileges senior to those of our common stock. Further, the issuance and sale of, or the perception that we may issue and sell, additional shares of common stock pursuant to our “at the market” equity offering program or an additional private placement or another offering could have the effect of depressing the market price of our common stock or increasing the volatility thereof.

Any issuance by us or sales of our securities by our security holders, including by any of our affiliates, or the perception that such issuances or sales could occur, could negatively impact the market price of our securities. For example, a number of shareholders own significant blocks of our common stock. If one or more of these large shareholders were to sell large portions of their holdings in a relatively short time, for liquidity or other reasons, the prevailing market price of our common stock could be negatively affected. This could result in further potential dilution to our existing shareholders and the impairment of our ability to raise capital through the sale of equity, debt or other securities.

We may be unable to maintain compliance with Nasdaq Marketplace Rules which could cause our common stock to be delisted from the Nasdaq Global Market. This could result in the lack of a market for our common stock, cause a decrease in the value of our common stock, and adversely affect our business, financial condition and results of operations.

Under the Nasdaq Marketplace Rules our common stock must maintain a minimum price of $1.00 per share for continued inclusion on the Nasdaq Global Market. Our stock price was previously below $1.00 on May 6, 2009 and was $1.22 on February 12, 2016 and we cannot guarantee that our stock price will remain at or above $1.00 per share. If the price again drops below $1.00 per share, our stock could become subject to delisting, and we may seek shareholder approval for a reverse stock split, which in turn could produce adverse effects and may not result in a long-term or permanent increase in the price of our common stock. Further, for continued listing on the Nasdaq Global Market we must have at least 400 total shareholders.

In addition to the minimum $1.00 per share and 400 total shareholders requirements, the Nasdaq Global Market has other continued listing requirements, and we must meet all of the criteria under at least one of the following three standards: (i) a minimum of $50.0 million in total asset value and $50.0 million in revenues in the latest fiscal year or in two of the last three fiscal years, at least 1.1 million publicly held shares and at least $15 million in market value of publicly held shares and at least four registered and active market makers (as such term is defined by the Nasdaq Marketplace Rules); ; (ii) a minimum of $50.0 million in market value of listed securities, at least 1.1 million publicly held shares and at least $15.0 million in market value of publicly held shares and at least four registered and active market makers; or (iii) a minimum of $10.0 million in shareholders' equity, at least 750,000 publicly held shares and at least $5 million in market value of publicly held shares and at least two registered and active market makers. As of December 31, 2021, we were in compliance with these listing requirements. Our stock price is volatile and we believe that we continue to remain susceptible to the market value of our listed securities and/or the market value of our publicly held securities falling below $50.0 million and $15.0 million, respectively. Accordingly, we cannot assure you that we will be able to continue to comply with Nasdaq Global Market’s listing requirements. Should we be unable to remain in compliance with these requirements, our stock could become subject to delisting.

36

If our common stock is delisted, trading of the stock will most likely take place on an over-the-counter market established for unlisted securities. An investor is likely to find it less convenient to sell, or to obtain accurate quotations in seeking to buy, our common stock on an over-the-counter market, and many investors may not buy or sell our common stock due to difficulty in accessing over-the-counter markets, or due to policies preventing them from trading in securities not listed on a national exchange or other reasons. For these reasons and others, delisting would adversely affect the liquidity, trading volume and price of our common stock, causing the value of an investment in us to decrease and having an adverse effect on our business, financial condition and results of operations by limiting our ability to attract and retain qualified executives and employees and limiting our ability to raise capital.

The anti-takeover provisions of Oregon law and in our articles of incorporation could adversely affect the rights of the holders of our common stock, including by preventing a sale or takeover of us at a price or prices favorable to the holders of our common stock.

Provisions of our articles of incorporation and bylaws and provisions of Oregon law may have the effect of delaying or preventing a merger or acquisition of us, making a merger or acquisition of us less desirable to a potential acquirer or preventing a change in our management, even if our shareholders consider the merger, acquisition or change in management favorable or if doing so would benefit our shareholders. In addition, these provisions could limit the price that investors would be willing to pay in the future for shares of our common stock. The following are examples of such provisions:

•if the number of directors is fixed by the board at eight or more, our board of directors is divided into three classes serving staggered terms, which would make it more difficult for a group of shareholders to quickly replace a majority of directors;

•our board of directors is authorized, without prior shareholder approval, to create and issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to acquire us or to effect a change of control, commonly referred to as "blank check" preferred stock;

•members of our board of directors can be removed only for cause and at a meeting of shareholders called expressly for that purpose, by the vote of 75 percent of the votes then entitled to be cast for the election of directors;

•our board of directors may alter our bylaws without obtaining shareholder approval; and shareholders are required to provide advance notice for nominations for election to the board of directors or for proposing matters to be acted upon at a shareholder meeting;

•Oregon law permits our board to consider other factors beyond stockholder value in evaluating any acquisition offer (so-called "expanded constituency" provisions); and

•a supermajority (67%) vote of shareholders is required to approve certain fundamental transactions.

Item 3.Legal Proceedings.

We are subject to legal matters that arise from time to time in the ordinary course of our business. Although we currently believe that resolving such matters, individually or in the aggregate, will not have a material adverse effect on our financial position, our results of operations, or our cash flows, these matters are subject to inherent uncertainties and our view of these matters may change in the future.

PART II

Item 5.Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

Market for Registrant’s Common Equity and Related Stockholder Matters

Our common stock is listed for trading on the Nasdaq Global Market under the symbol "PXLW". Our stock began trading on May 19, 2000.

As of March 4, 2022, there were 114 shareholders of record of our common stock and the last per share sales price of the common stock on that date was $2.96. The number of beneficial owners of our common stock is substantially greater than the number of shareholders of record because a significant portion of our outstanding common stock is held in broker "street name" for the benefit of individual investors.

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

COVID-19

In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic, and the virus continues to exist in areas where we operate and sell our products and services. Several public health organizations have recommended, and many local governments have implemented, certain measures to slow and limit the transmission of the virus, including various social distancing ordinances, which has resulted in a significant deterioration of economic conditions in many of the countries in which we operate.

The spread of COVID-19 has caused us to modify our business practices, including implementing work-from-home policies and restricting travel by our employees.

The impact of the pandemic on the global economy and on our business, as well as on the business of our suppliers and customers, and the measures that may be needed in the future in response to it, will depend on many factors beyond our control and knowledge. We will continually monitor the situation to determine what actions may be necessary or appropriate to address the impact of the pandemic, which may include actions mandated or recommended by federal, state or local authorities. While we expect the impacts of COVID-19 to be temporary, the disruptions caused by the virus have negatively affected our revenue and results of operations in 2020 and 2021. For example, our revenues for fiscal year 2020 were lower than initially anticipated and our revenues for 2021 continued to be negatively impacted by COVID-19.

Overview

Pixelworks is a leading provider of high-performance and power-efficient visual processing solutions that bridge the gap between video content formats and rapidly advancing display capabilities. We develop and market semiconductor and software solutions that enable consistently high-quality, authentic viewing experiences in a wide variety of applications from cinema to smartphones. Our primary target markets include Mobile (smartphone, gaming and tablet), Home Entertainment (TV, personal video recorder ("PVR"), over-the-air ("OTA") and projector), Content (creation, remastering and delivery), and Business & Education (projector).

We were one of the first companies to commercially launch a video System on Chip ("SoC") capable of deinterlacing 1080i HDTV signals and one of the first companies with a commercial dual-channel 1080i deinterlacer integrated circuit. Our Topaz product line was one of the industry’s first single-chip SoC for digital projection. We first introduced our motion estimation / motion compensation technology ("MEMC") for TVs and in recent years introduced a mobile-optimized MEMC solution for smartphones, one of several unique features in the mobile-optimized Iris visual processor. In 2019, we introduced our Hollywood award-winning TrueCut® video platform, the industry’s first motion grading technology that allows fine tuning of motion appearance in cinematic content for a wide range of frame rates, shutter angles and display types.

Our solutions enable worldwide manufacturers to offer leading-edge consumer electronics and professional display products, as well as video delivery and streaming solutions for content service providers. Our core visual display processing technology intelligently processes digital images and video from a variety of sources and optimizes the content for a superior viewing experience. Our video coding technology reduces storage requirements, significantly reduces bandwidth constraint issues and converts content between multiple formats to enable seamless delivery of video, including OTA streaming, while also maintaining end-to-end content security.

Rapid growth in video consumption, combined with the move towards high frame rate / refresh rate displays, especially in mobile, is increasing the demand for our visual processing and video delivery solutions. Our technologies can be applied to a wide range of devices from large-screen projectors to cinematic big screens, to low-power mobile tablets and smartphones, to high-quality video infrastructure equipment and streaming devices. Our products are architected and optimized for power, cost, bandwidth, and overall system performance, according to the requirements of the specific application. On occasion, we have also licensed our technology.

During the third quarter of 2021, we engaged in a strategic plan to re-align our mobile, projector, and video delivery businesses to improve their focus on the Asia-centered customers and employee stakeholders of those businesses. The global center of the mobile, projector, and video delivery businesses continues to be in Asia, and the steps taken by us to date and going forward are intended to improve our ability to access capital, customers, and talent. We have operated our primary R&D center in Asia for over 15 years and feel that the time is right to take advantage of that existing footprint and develop PWSH as a full profit-and-loss center underneath Pixelworks, Inc., for the mobile, projector, and video delivery businesses. Most of these steps were completed before the end of 2021.

40

This plan will further enable PWSH to seek qualification to file an application for an initial public offering on the Shanghai Stock Exchange’s Science and Technology Innovation Board, known as the STAR Market (the “Listing”). We believe that the Listing will have many benefits, including improved access to new capital markets and the funding of our growth worldwide. We presently intend to qualify PWSH to apply for the Listing so that the Listing is consummated in 2023. The process of going public on the STAR Market includes several periods of review and, therefore, is a lengthy process. There is no guarantee that PWSH will be approved for a Listing at any point in the future.

As of December 31, 2021, we had an intellectual property portfolio of 335 patents related to the visual display of digital image data. We focus our research and development efforts on developing video algorithms that improve quality and architectures that reduce system power, cost, bandwidth and increase overall system performance and device functionality. We seek to expand our technology portfolio through internal development and co-development with business partners, and we continually evaluate acquisition opportunities and other ways to leverage our technology into other high-value markets.

Pixelworks was founded in 1997 and is incorporated under the laws of the state of Oregon. On August 2, 2017, we acquired ViXS Systems Inc., a corporation organized in Canada ("ViXS").

Historically, significant portions of our revenue have been generated by sales to a relatively small number of end customers and distributors. We sell our products worldwide through a direct sales force, distributors and manufacturers’ representatives. We sell to distributors in China, Europe, Japan, Korea, Southeast Asia, Taiwan and the U.S. Our distributors often provide engineering support to our end customers and often have valuable and established relationships with our end customers. In certain countries in which we operate, it is customary to sell to distributors. While distributor payment to us is not dependent upon the distributor’s ability to resell the product or to collect from the end customer, the distributors may provide longer payment terms to end customers than those we would offer.

Significant portions of our products are sold overseas. Sales outside the U.S. accounted for approximately 97% and 93% of revenue in 2021 and 2020, respectively. Our integrators, branded manufacturers and branded suppliers incorporate our products into systems that are sold worldwide. The majority of our revenue to date has been denominated in U.S. dollars.

Seasonality

Our business is subject to seasonality related to the markets we serve and the location of our customers. For example, we have historically experienced higher revenue from the digital projector market in the third quarter of the year, and lower revenue in the first quarter of the year, as our Japanese customers reduce inventories in anticipation of their March 31 fiscal year end.

Results of Operations

For the year ended December 31, 2021 compared with year ended December 31, 2020.

Revenue, net

Net revenue was as follows (in thousands):

	Year ended December 31,				2021 v. 2020
	2021		2020		$ change		% change
Revenue, net	$	55,102	$	40,855	$	14,247	35	%

Net revenue increased $14.2 million, or 35%, from 2020 to 2021.

Revenue recorded in 2021 consisted of $50.8 million in revenue from the sale of IC products and $4.3 million in revenue related to engineering services, license revenue and other. Revenue recorded in 2020 consisted of $39.2 million in revenue from the sale of IC products and $1.7 million in revenue related to engineering services, license revenue and other.

The increase in IC revenue is due to a significant increase in unit sales into the mobile market and an increase in unit sales into the digital projector market as we experienced increased demand in the mobile market and sustained recovery in the digital projector market.

The increase in revenue related to engineering services, license revenue and other is primarily due to the recognition of license revenue during 2021.

Cost of revenue and gross profit

Cost of revenue and gross profit were as follows (in thousands):

	Year ended December 31,
	2021		% of  revenue		2020		% of  revenue
Direct product costs and related overhead 1	$	25,987	47	%	$	18,807	46	%
Amortization of acquired developed technology	899		2		1,192		3
Inventory charges 2	480		1		66		0
Stock-based compensation	43		0		432		1
Restructuring	—		0		173		0
Total cost of revenue	$	27,409	50	%	$	20,670	51	%
Gross profit	$	27,693	50	%	$	20,185	49	%

1Includes purchased materials, assembly, test, labor, employee benefits and royalties.

2Includes charges to reduce inventory to lower of cost or net realizable value and a benefit for sales of previously written down inventory.

Gross profit margin increased to 50% in 2021 compared to 49% in 2020, primarily due to high margin license revenue recorded, more absorption of fixed overhead costs due to increased revenue and decreased amortization of acquired developed technology. These favorable increases to gross profit margin were partially offset by an unfavorable impact to gross profit margin due to a significant increase in sales into the mobile market compared to the comparable period.

Pixelworks’ gross profit margin is subject to variability based on changes in revenue levels, product mix, average selling prices, startup costs, restructuring charges, amortization related to acquired developed technology and the timing and execution of manufacturing ramps as well as other factors.

42

Research and development

Research and development expense includes compensation and related costs for personnel, development-related expenses including non-recurring engineering and fees for outside services, depreciation and amortization, expensed equipment, facilities and information technology expense allocations and travel and related expenses.

Co-Development Agreement

During the third quarter of 2021, we entered into a best-efforts co-development agreement with a customer to defray a portion of the research and development expenses we expect to incur in connection with our development of an integrated circuit product. We expect our development costs to exceed the amounts received from the customer, and although we expect to sell units of the product to the customer, there is no commitment or agreement from the customer for such sales at this time. Additionally, we retain ownership of any modifications or improvements to our pre-existing intellectual property and may use such improvements in products sold to other customers.

Under the co-development agreement, $5.8 million was payable by the customer within 60 days of the date of the agreement and three additional payments of $2.2 million, $1.3 million and $1.3 million are each payable upon completion of certain development milestones. As amounts become due and payable, they are offset against research and development expense on a pro rata basis. During the year ended December 31, 2021, we recognized an offset to research and development expense of approximately $4.0 million.

Research and development expense was as follows (in thousands):

	Year ended December 31,				2021 v. 2020
	2021		2020		$ change		% change
Research and development	$	27,250	$	25,040	$	2,210	9	%

Research and development expense increased $2.2 million, or 9%, from 2020 to 2021. The increase was primarily due to an increase in compensation expense due to a COVID-19 relief benefit received in China in 2020 that was not received in 2021, as well as annual merit salary increases and an increased management bonus accrual. 2021 also included an increase in non-recurring engineering expense due to the timing of development activities. This increase was largely offset by a benefit related to the co-development agreement. 

Selling, general and administrative

Selling, general and administrative expense includes compensation and related costs for personnel, sales commissions, allocations for facilities and information technology expenses, travel, outside services and other general expenses incurred in our sales, marketing, customer support, management, legal and other professional and administrative support functions.

Selling, general and administrative expense was as follows (in thousands): 

	Year ended December 31,				2021 v. 2020
	2021		2020		$ change		% change
Selling, general and administrative	$	20,445	$	19,840	$	605	3	%

Selling, general and administrative expense increased $0.6 million, or 3%, from 2020 to 2021. The increase was primarily due to increases in accounting and legal fees incurred related to our strategic plan with our PWSH subsidiary as well as an increase in compensation expense due to annual merit salary increases and an increased management bonus accrual. These increases were partially offset by a decrease in stock-based compensation expense due to the timing of awards granted.

43

Restructurings

In August 2020, we executed a restructuring plan to make the operation of the Company more efficient (the "August 2020 Plan"). The August 2020 Plan included an approximately 14% reduction in workforce, primarily in the areas of operations, research and development, sales and marketing.

In January 2020, we executed a restructuring plan to make the operation of the Company more efficient (the "January 2020 Plan"). The January 2020 Plan included an approximately 4% reduction in workforce, primarily in the areas of research and development and sales.

Restructuring expense was as follows (in thousands): 

	Year ended December 31,
	2021		2020
Employee severance and benefits	$	—	$	2,214
Total restructuring expense	$	—	$	2,214
Included in cost of revenue	$	—	$	173
Included in operating expenses	—		2,041

During 2021, we did not record any restructuring expense.

During 2020, we recorded $1.6 million in restructuring expense related to the August 2020 Plan and $0.6 million in restructuring expense related to the January 2020 Plan. The January 2020 Plan was complete in the first quarter of 2020 and we did not incur any further charges related to the January 2020 Plan after the first quarter of 2020. The August 2020 Plan was complete in the fourth quarter of 2020 and we did not incur any further expenses related to the August 2020 Plan after the fourth quarter of 2020.

Interest income and other, net

Interest income and other, net, consisted of the following (in thousands):

	Year ended December 31,
	2021		2020
Other income	$	246	$	161
Interest income	211		87
Interest expense	—		(239)
Total interest income and other, net	$	457	$	9

Provision (benefit) for income taxes

The provision (benefit) for income taxes was as follows (in thousands):

	Year ended December 31,
	2021		2020
Provision (benefit) for income taxes	$	(133)	$	598

The income tax benefit of $0.1 million recorded for the year ended December 31, 2021 is primarily comprised of current tax expense of approximately $0.6 million for our profitable cost-plus foreign jurisdictions and accruals for tax contingencies in foreign jurisdictions offset by a deferred tax benefit of approximately $0.7 million primarily associated with recognition of Canadian deferred tax assets. Included in current tax expense is a tax benefit of $0.6 million associated with the reversal of withholding taxes on our China earnings as we now plan to reinvest these earnings indefinitely, which resulted from the changes made in the third quarter of 2021 related to our strategic plan with our PWSH subsidiary. Also included in current tax expense is $0.8 million of expense resulting from the revaluation of our uncertain tax position in China to the statutory tax rate as we no longer qualify for the tax holiday we were under.

The income tax expense recorded for the year ended December 31, 2020 is primarily comprised of $0.6 million in current and deferred tax expense for our profitable cost-plus foreign jurisdictions and accruals for tax contingencies in foreign jurisdictions, partially offset by the reversal of previously recorded tax contingencies due to the expiration of the applicable statute of limitations.

We continue to record a full valuation allowance against our U.S. net deferred tax assets as of December 31, 2021 and 2020, as it is not more likely than not that we will realize a benefit from these assets in a future period. In the third quarter of 2021, we recorded a valuation allowance against our net deferred tax assets in China in conjunction with the restructuring of our intercompany agreements and intellectual property. In the fourth quarter of 2021, we recognized $0.6 million of our Canadian net deferred tax assets as we are more likely than not to realize a benefit from these assets in a future period. We have not provided a valuation allowance against our other foreign net deferred tax assets as we have concluded it is more likely than not that we will realize a benefit from these assets in a future period because our subsidiaries in these jurisdictions are cost-plus taxpayers.

As of December 31, 2021, we have federal, state and foreign net operating loss carryforwards of approximately $166.4 million, $6.8 million, and $39.5 million respectively, which will begin expiring in 2022. As of December 31, 2021, we have available federal, state and foreign research and experimentation tax credit carryforwards of approximately $7.8 million, $5.0 million and $24.3 million respectively. The federal and state tax credits will begin expiring in 2022 while the foreign tax credits have an indefinite life. In addition, our Canadian subsidiary has unclaimed scientific and experimental expenditures to be carried forward and applied against future income in Canada of approximately $120.9 million. We have a general foreign tax credit of $0.1 million, which will begin expiring in 2022. Our ability to utilize our federal net operating losses may be limited by Section 382 of the Internal Revenue Code of 1986, as amended, which imposes an annual limit on the ability of a corporation that undergoes an "ownership change" to use its net operating loss carryforwards to reduce its tax liability. An ownership change is generally defined as a greater than 50% increase in equity ownership by 5% shareholders in any three-year period.

Liquidity and Capital Resources

Cash and cash equivalents

Total cash and cash equivalents increased $30.3 million from $31.3 million at December 31, 2020 to $61.6 million at December 31, 2021. Short-term marketable securities decreased $0.3 million from $0.3 million at December 31, 2020 to zero at December 31, 2021. The net increase in cash, cash equivalents and short-term marketable securities of $30.0 million was the result of $42.3 million in proceeds from equity interests issued to the redeemable non-controlling interest and certain entities owned by employees, $1.3 million in proceeds from the issuances of common stock under our employee equity incentive plans and $0.3 million in net proceeds from our "at the market" equity offering. These increases were partially offset by $9.2 million used in operating activities, $3.5 million used for purchases of property and equipment and $1.2 million used for payments on other asset financings.

As of December 31, 2021, our cash and cash equivalents balance consisted of $46.3 million in cash and $15.3 million in cash equivalents held in U.S. dollar denominated money market funds. Our investment policy requires that our portfolio maintains a weighted average maturity of less than 12 months. Additionally, no maturities can extend beyond 24 months and concentrations with individual securities are limited. At the time of purchase, short-term credit rating must be rated at least A-2 / P-2 / F-2 by at least two Nationally Recognized Statistical Rating Organizations ("NRSRO") and securities of issuers with a long-term credit rating must be rated at least A or A3 by at least two NRSROs. Our investment policy is reviewed at least annually by our Audit Committee.

Accounts receivable, net

Accounts receivable, net increased to $8.7 million at December 31, 2021 from $4.7 million at December 31, 2020. Average number of days sales outstanding increased to 47 days at December 31, 2021 from 44 days at December 31, 2020. The increase in accounts receivable was due to normal fluctuations in the timing of sales and customer receipts within the fourth quarter of 2021, and the fourth quarter of 2020.

Inventories

Inventories decreased to $1.5 million at December 31, 2021 from $2.4 million at December 31, 2020. Inventory turnover increased to 19.5 at December 31, 2021 from 6.0 at December 31, 2020 primarily due to lower average inventory balances and higher cost of goods sold during the fourth quarter of 2021 compared to the fourth quarter of 2020. Inventory turnover is calculated based on annualized quarterly operating results and average inventory balances during the quarter.

Capital resources

At the Market Offering

On June 5, 2020, we entered into a sales agreement (the "Sales Agreement") with Cowen and Company, LLC ("Cowen"), pursuant to which we may issue and sell shares of the Company's common stock, par value $0.001 per share, having an aggregate offering price of up to $25.0 million, from time to time, through an "at the market" equity offering program under which Cowen will act as sales agent. Under the Sales Agreement, Cowen may sell the shares by methods deemed to be an "at the market offering" as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended, including sales made by means of ordinary brokers’ transactions on the Nasdaq Global Market or on any other existing trading market for the common stock or otherwise at market prices prevailing at the time of sale, in block transactions, or as otherwise directed by us. We pay Cowen a commission equal to three percent (3.0%) of the gross sales proceeds of any common stock sold through Cowen under the Sales Agreement. The Sales Agreement may be terminated by us upon prior notice to Cowen or by Cowen upon prior notice to us, or at any time under certain circumstances, including but not limited to the occurrence of a material adverse change in the Company. We are not obligated to sell any shares under the Sales Agreement.

During the year ended December 31, 2020, we sold an aggregate of 1,747,466 shares of our common stock under this at the market offering, resulting in aggregate net proceeds to us of approximately $4.4 million, and gross proceeds of approximately $4.9 million and paid Cowen commissions and fees of approximately $0.2 million, and other expenses of $0.3 million.

During the year ended December 31, 2021, we sold an aggregate of 61,018 shares of our common stock under this at the market offering, resulting in aggregate net proceeds to us of approximately $0.3 million, and gross proceeds of approximately $0.4 million, and paid Cowen commissions and fees and other expenses of approximately $0.1 million.

46

Capital Increase Agreement

We have entered into a Capital Increase Agreement pursuant to which our subsidiary PWSH, received net proceeds from the sale of its securities pursuant thereto in an amount of RMB 279.7 million ($42.3 million USD). Additional information is provided in "Note 15: Redeemable Non-Controlling Interest and Equity Interest of PWSH Sold to Employees", which is incorporated by reference into this section.

Liquidity

As of December 31, 2021, our cash, cash equivalents and short-term marketable securities balance of $61.6 million was highly liquid. We currently anticipate that our existing working capital will be adequate to fund our operating, investing and financing needs for the twelve months following our 2021 fiscal year end and beyond. We may pursue financing arrangements including the issuance of debt or equity securities or reduce expenditures, or both, to meet the Company’s cash requirements, including in the longer term. There is no assurance that, if required, we will be able to raise additional capital or reduce discretionary spending to provide the required liquidity which, in turn, may have an adverse effect on our results of operations, financial position and cash flows.

From time to time, we evaluate acquisitions of businesses, products or technologies that complement our business. Any transactions, if consummated, may consume a material portion of our working capital or require the issuance of equity securities that may result in dilution to existing shareholders. Our ability to generate cash from operations is also subject to substantial risks described in Part I, “Item 1A., Risk Factors.” If any of these risks occur, we may be unable to generate or sustain positive cash flow from operating activities. We would then be required to use existing cash and cash equivalents to support our working capital and other cash requirements. If additional funds are required to support our working capital requirements, acquisitions or other purposes, we may seek to raise funds through debt financing, equity financing or from other sources. If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our shareholders could be significantly diluted, and these newly-issued securities may have rights, preferences or privileges senior to those of existing shareholders. If we raise additional funds by obtaining loans from third parties, the terms of those financing arrangements may include negative covenants or other restrictions on our business that could impair our operating flexibility, and would also require us to incur interest expense. We can provide no assurance that additional financing will be available at all or, if available, that we would be able to obtain additional financing on terms favorable to us.

Contractual Payment Obligations

A summary of our contractual obligations as of December 31, 2021 is as follows:

	Payments Due By Period
Contractual Obligation	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years
Operating leases	$	5,724	$	2,652	$	2,253	$	728	$	91
Estimated purchase commitments to contract manufacturers	6,598		6,598		—		—		—
Payments on accrued balances related to asset financings	1,498		1,133		365		—		—
Other purchase obligations and commitments	619		275		344		—		—
Total 1	$	14,439	$	10,658	$	2,962	$	728	$	91

1    We are unable to reliably estimate the timing of future payments related to uncertain tax positions and repatriation of foreign earnings; therefore, $3.1 million of income taxes payable has been excluded from the table above.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires us to make estimates and judgments that affect the amounts reported. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, inventories, property and equipment, impairment of long-lived assets, valuation of goodwill, valuation of share-based payments, income taxes, litigation and other contingencies. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements:

47

Revenue Recognition - Revenue is recognized when control of the promised good or service is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our principal revenue generating activities consist of the following:

Product Sales - We sell integrated circuit products, also known as "chips" or "ICs", based upon a customer purchase order, which includes a fixed price per unit. We have elected to account for shipping and handling as activities to fulfill the promise to transfer the goods, and not evaluate whether these activities are promised services to the customer. We generally satisfy our single performance obligation upon shipment of the goods to the customer and recognize revenue at a point in time upon shipment of the underlying product.

Our shipments are subject to limited return rights subject to our limited warranty for our products sold. In addition, we may provide other credits to certain customers pursuant to price protection and stock rotation rights, all of which are considered variable consideration when estimating the amount of revenue to recognize. We use the “most likely amount” method to determine the amount of consideration to which we are entitled. Our estimate of variable consideration is reassessed at the end of each reporting period based on changes in facts and circumstances. Historically, returns and credits have not been material.

Engineering Services - We enter into contracts for professional engineering services that include software development and customization. We identify each performance obligation in our engineering services agreements ("ESAs") at contract inception. The ESA generally includes project deliverables specified by the customer. The performance obligations in the ESA are generally combined into one deliverable, with the pricing for services stated at a fixed amount. Services provided under the ESA generally result in the transfer of control over time. We recognize revenue on ESAs based on the proportion of labor hours expended to the total hours expected to complete the contract performance obligation. ESAs could include substantive customer acceptance provisions. In ESAs that include substantive customer acceptance provisions, we recognize revenue upon customer acceptance.

License Revenue - On occasion, we derive revenue from the license of our internally developed intellectual property ("IP"). Additionally, for certain IP license agreements, royalties are collected as customers sell their own products that incorporate our IP. IP licensing agreements that we enter into generally provide licensees the right to incorporate our IP components in their products with terms and conditions that vary by licensee. Fees under these agreements generally include license fees or royalty fees relating to our IP and support service fees, resulting in two performance obligations. We evaluate each performance obligation, which generally results in the transfer of control at a point in time for the license fee and over time for support services. Royalties are recognized as revenue is earned, generally when the customer sells its products that incorporate our IP.

Other - From time-to-time, we enter into arrangements for other revenue generating activities, such as providing technical support services to customers through technical support agreements. In each circumstance, we evaluate such arrangements for our performance obligations which generally results in the transfer of control for such services over time. Historically, such arrangements have not been material to our operating results.

Inventory Valuation. We value inventory at the lower of cost or net realizable value. In addition, we write down any obsolete, unmarketable or otherwise impaired inventory to net realizable value. The determination of obsolete or excess inventory requires us to estimate the future demand for our products. The estimate of future demand is compared to inventory levels to determine the amount, if any, of obsolete or excess inventory. If actual market conditions are less favorable than those we projected at the time the inventory was written down, additional inventory write-downs may be required. Inventory valuation is re-evaluated on a quarterly basis.

Useful Lives and Recoverability of Equipment and Other Long-Lived Assets. We evaluate the recoverability of equipment and other assets, including identifiable intangible assets, whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If there is an indicator of impairment, we prepare an estimate of future, undiscounted cash flows expected to result from the use of each asset and its eventual disposition. If these cash flows are less than the carrying value of the asset, we adjust the carrying amount of the asset to its estimated fair value. We have concluded that the carrying value of our long-lived assets is recoverable as of December 31, 2021.

Goodwill. Goodwill is not amortized, rather tested, at least annually, for impairment at a reporting unit level. Impairment of goodwill is the condition that exists when the carrying amount of a reporting unit that includes goodwill exceeds its fair value. A goodwill impairment loss is recognized for the amount that the carrying amount of the reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit. If the fair value of a reporting unit exceeds the carrying amount, goodwill of the reporting unit is not considered impaired.

48

We evaluate impairment using the guidance set forth in FASB Accounting Standards Update No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04") which states that an entity may first assess qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. If determined to be necessary, the quantitative impairment test shall be used to identify goodwill impairment and measure the amount of goodwill impairment loss to be recognized. An entity has an unconditional option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to the quantitative goodwill impairment test. Accordingly, we have elected to bypass the qualitative assessment and proceed directly to the quantitative goodwill impairment test. We tested goodwill for impairment under the quantitative goodwill impairment test during the fourth quarter and concluded that goodwill was not impaired.

Stock-Based Compensation. Stock-based compensation expense is measured at the grant date, based on the estimated fair value of the award using the Black-Scholes option pricing model for stock options and market price for restricted stock units. The use of the Black-Scholes option pricing model, requires certain estimates, including expected term of options granted, the method of calculating expected volatilities and the risk-free interest rate used in the option-pricing model. The resulting calculated fair value of stock options is recognized as compensation expense over the requisite service period, which is generally the vesting period. When there are changes to the assumptions used in the option-pricing model, including fluctuations in the market price of our common stock, there will be variations in the calculated fair value of our future stock option awards, which results in variation in the stock-based compensation expensed recognized. Additionally, any modification of an award that increases its fair value will require us to recognize additional expense.

Income Taxes. We record deferred income taxes for temporary differences between the amount of assets and liabilities for financial and tax reporting purposes and we record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. We also regularly conduct a comprehensive review of our uncertain tax positions. In this regard, an uncertain tax position represents our expected treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for financial reporting purposes. Until these positions are sustained by the taxing authorities, we do not recognize the tax benefits resulting from such positions and report the tax effects for uncertain tax positions in our consolidated balance sheets.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Pixelworks, Inc. and its subsidiaries (the Company) as of December 31, 2021 and 2020, and the related consolidated statements of operations, comprehensive loss, shareholders' equity, and cash flows for each of the two years ended December 31, 2021, and the related notes (collectively referred to as the consolidated financial statements).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the two years ended December 31, 2021 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

The Company's management is responsible for these consolidated financial statements. Our responsibility is to express an opinion on the Company's consolidated financial statements. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provides a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Revenue Recognition — Refer to Note 2 to the Consolidated Financial Statements

____________________________________________________________________________

Critical Audit Matter Description

The Company recognizes revenue upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company's contract may contain one or more performance obligations, including hardware, professional engineering services, internally developed intellectual property ("IP") and technical support services.

Significant judgment is exercised by the Company in determining revenue recognition for these customer agreements, and includes the following:

•Determination of whether products and services are considered distinct performance obligations that should be accounted for separately versus together.

•Determination of stand-alone selling prices for each distinct performance obligation (i.e. for IP license fee and support service fee that are sold together under IP licensing arrangements).

•The pattern of delivery (i.e., timing of when revenue is recognized) for each distinct performance obligation.

•Estimation of variable consideration when determining the amount of revenue to recognize, primarily on product sale arrangements (e.g., customer credits pursuant to price protection rights, stock rotation rights and limited return rights).

Given these factors, the related audit effort in evaluating management's judgments in determining revenue recognition for these customer agreements was extensive and required a high degree of auditor judgment.

____________________________________________________________________________

How the Critical Audit Matter Was Addressed in the Audit

Our principal audit procedures related to the Company's revenue recognition for these customer agreements included the following:

•We selected a sample of customer agreements and performed the following procedures:

◦Obtained and read contract source documents for each selection, including master agreements, and other documents that were part of the agreement to identify significant terms.

◦Tested management's identification of significant terms for completeness, including the identification of distinct performance obligations and variable consideration.

◦Assessed the terms in the customer agreement and evaluated the appropriateness of management's application of their accounting policies, along with their use of estimates, in the determination of revenue recognition conclusions.

•We evaluated the reasonableness of management's estimate of stand-alone selling prices for products and services that are not sold separately.

•We evaluated the reasonableness and accuracy of management's judgements and estimates used in accounting for customer credits pursuant to price protection rights, stock rotation rights and limited return rights ("variable consideration"). This included testing management's estimate of calculating expected credits issued to customers and determining whether such credits were completely and accurately reserved as of December 31, 2021.

We tested the mathematical accuracy of management's calculations of revenue and the associated timing of recognizing the related revenue subject to any constraints in the consolidated financial statements.

51

Inventory Valuation— Refer to Note 2 to the Financial Statements

____________________________________________________________________________

Critical Audit Matter Description

The Company computes inventory cost on a first-in-first out basis and applies judgment in determining the forecast for products and the valuation of inventories. The Company assesses inventory at each reporting date in order to assert that it is recorded at net realizable value, giving consideration to, among other factors: whether the product is valued at the lower of cost or net realizable value; and the estimation of excess and obsolete inventory or that which is not of saleable quality. Most of the Company's inventory provisions are based on the Company's inventory levels and future product purchase commitments compared to assumptions about future demand and market conditions.

Significant judgment is exercised by the Company to determine inventory carrying value adjustments, specifically the provisions for excess or obsolete inventories, and includes the following:

•Developing assumptions such as forecasts of future sales quantities, which are sensitive to the competitiveness of product offerings, customer requirements, and product life cycles.

•Applying management judgment on not reserving certain inventory units (e.g. in case they are items that can be used for Return Merchandise Authorization "RMA"/warranty purpose).

Given these factors and assumptions are forward-looking and could be affected by future economic and market conditions, the related audit effort to evaluate management's inventory valuation adjustments was extensive and required a high degree of auditor judgment.

____________________________________________________________________________

How the Critical Audit Matter Was Addressed in the Audit

Our principal audit procedures related to the Company's inventory valuation methodology included the following:

•We selected a sample of inventory items and performed the following procedures:

◦Tested the mathematical accuracy of the schedule by comparing the quantities and carrying value of on-hand inventories to related unit sales, both historical and forecasted.

◦Assessed and tested the reasonableness of the significant assumptions (e.g., sales and marketing forecast, build plans, RMA requirements, usage and open sales-orders).

◦Inquired with the management team and evaluated the adequacy of management's sales forecasts by analyzing potential technological changes in line with product life cycles and/or identified alternative customer uses.

Assessed whether there were any potential sources of contrary information, including historical forecast accuracy or history of significant revisions to previously recorded inventory valuation adjustments, and performed sensitivity analyses over significant assumptions to evaluate the changes in inventory valuation that would result from changes in the assumptions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(In thousands, except share and per share data)

NOTE 1.        BASIS OF PRESENTATION

Nature of Business

Pixelworks is a leading provider of high-performance and power-efficient visual processing solutions that bridge the gap between video content formats and rapidly advancing display capabilities. We develop and market semiconductor and software solutions that enable consistently high-quality, authentic viewing experiences in a wide variety of applications from cinema to smartphones. Our primary target markets include Mobile (smartphone, gaming and tablet), Home Entertainment (TV, personal video recorder ("PVR"), over-the-air ("OTA") and projector), Content (creation, remastering and delivery), and Business & Education (projector).

As of December 31, 2021, we had an intellectual property portfolio of 335 patents related to the visual display of digital image data. We focus our research and development efforts on developing video algorithms that improve quality, and architectures that reduce system power, cost, bandwidth and increase overall system performance and device functionality. We seek to expand our technology portfolio through internal development and co-development with business partners, and we continually evaluate acquisition opportunities and other ways to leverage our technology into other high-value markets.

Pixelworks was founded in 1997 and is incorporated under the laws of the state of Oregon. On August 2, 2017, we acquired ViXS Systems, Inc., a corporation organized in Canada ("ViXS") ("the Acquisition").

During the third quarter of 2021, we engaged in a strategic plan to re-align our mobile, projector, and video delivery businesses to improve their focus on the Asia-centered customers and employee stakeholders of those businesses. The global center of the mobile, projector, and video delivery businesses continues to be in Asia, and the steps we have taken to date and going forward are intended to improve our ability to access capital, customers, and talent. We have operated our primary R&D center in Asia for over 15 years and feel that the time is right to take advantage of that existing footprint and develop our subsidiary, Pixelworks Semiconductor Technology (Shanghai) Co., Ltd. (or "PWSH") as a full profit-and-loss center underneath Pixelworks, Inc. for the mobile, projector, and video delivery businesses. Most of these steps have been completed as of the end of 2021.

This plan will further enable PWSH to seek qualification to file an application for an initial public offering on the Shanghai Stock Exchange’s Science and Technology Innovation Board, known as the STAR Market (the “Listing”). We believe that the Listing will have many benefits, including improved access to new capital markets and the funding of its growth worldwide. We presently intend to qualify PWSH to apply for the Listing so that the Listing is consummated in 2023. The process of going public on the STAR Market includes several periods of review and, therefore, is a lengthy process. There is no guarantee that PWSH will be approved for a Listing at any point in the future.

Our consolidated financial statements include the accounts of Pixelworks and its subsidiaries. Intercompany accounts and transactions have been eliminated. All foreign subsidiaries use the U.S. dollar as the functional currency, and as a result, transaction gains and losses are included in the consolidated statements of operations. Transaction (gains) and losses were $(258) and $419 for the years ended December 31, 2021 and 2020, respectively.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") requires us to make estimates and judgments that affect amounts reported in the financial statements and accompanying notes. Our significant estimates and judgments include those related to revenue recognition, valuation of excess and obsolete inventory, lives and recoverability of equipment and other long-lived assets, valuation of goodwill, stock-based compensation and income taxes. The actual results experienced could differ materially from our estimates.

NOTE 2.        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash and Cash Equivalents

We classify all cash and highly liquid investments with original maturities of three months or less at the date of purchase as cash and cash equivalents. Cash equivalents, which as of December 31, 2021 and 2020 consisted of U.S. denominated money market funds, totaled $15,254 and $23,832 as of December 31, 2021 and 2020, respectively.

Marketable Securities

Our investments in marketable securities are classified as available-for-sale. Available-for-sale securities are stated at fair value based on quoted market prices with unrealized holding gains or losses, net of tax, included in accumulated other comprehensive income, a component of shareholders’ equity. The cost of securities sold is based on the specific identification method.

Accounts Receivable

Accounts receivable are recorded at invoiced amount and do not bear interest when recorded or accrue interest when past due. We maintain an allowance for doubtful accounts for estimated losses that may result from the inability of our customers to make required payments. At the end of each reporting period, we estimate the allowance for doubtful accounts based on an account-by-account risk analysis of outstanding receivable balances. The determination to write-off specific accounts receivable balances is made based on the likelihood of collection and past due status. Past due status is based on invoice date and terms specific to each customer.

Inventories

Inventories consist of finished goods and work-in-process, and are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market (net realizable value).

Property and Equipment

Property and equipment are stated at cost. Depreciation and amortization is calculated on a straight-line basis over the estimated useful life of the assets which are generally as follows:

Software	Lesser of 3 years or contractual license term
Equipment, furniture and fixtures	2 years
Tooling	2 to 4 years
Leasehold improvements	Lesser of lease term or estimated useful life

The cost of property and equipment repairs and maintenance is expensed as incurred.

Licensed Technology

We have capitalized licensed technology assets in other long-term assets. These assets are stated at cost and are amortized on a straight-line basis over the term of the license or the estimated life of the asset, if the license is not contractually limited, which is generally two to five years.

Useful Lives and Recoverability of Equipment and Other Long-Lived Assets

We evaluate the remaining useful life and recoverability of equipment and other assets, including identifiable intangible assets, whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If there is an indicator of impairment, we prepare an estimate of future, undiscounted cash flows expected to result from the use of each asset and its eventual disposition. If these cash flows are less than the carrying value of the asset, we adjust the carrying amount of the asset to its estimated fair value. We have concluded that the carrying value of our long-lived assets is recoverable as of December 31, 2021.

59

Goodwill

Goodwill is not amortized, rather it is tested, at least annually, for impairment at a reporting unit level. Impairment of goodwill is the condition that exists when the carrying amount of a reporting unit that includes goodwill exceeds its fair value. A goodwill impairment loss is recognized for the amount that the carrying amount of the reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit. If the fair value of a reporting unit exceeds the carrying amount, goodwill of the reporting unit is not considered impaired.

We evaluate impairment using the guidance set forth in FASB Accounting Standards Update No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04") which states that an entity may first assess qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. If determined to be necessary, the quantitative impairment test shall be used to identify goodwill impairment and measure the amount of goodwill impairment loss to be recognized. An entity has an unconditional option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to the quantitative goodwill impairment test. Accordingly, we have elected to bypass the qualitative assessment and proceed directly to the quantitative goodwill impairment test. We tested goodwill for impairment under the quantitative goodwill impairment test during the fourth quarter of 2021 and concluded that goodwill was not impaired.

Warranty Program

We warrant that our products will be free from defects in material and workmanship for a period of twelve months from delivery. Warranty repairs are guaranteed for the remainder of the original warranty period. Our warranty is limited to repairing or replacing products, or refunding the purchase price. At the end of each reporting period, we estimate a reserve for warranty returns based on historical experience and knowledge of any applicable events or transactions. The reserve for warranty returns is included in accrued liabilities in our consolidated balance sheets.

Stock-Based Compensation

We currently sponsor a stock incentive plan that allows for issuance of employee stock options and restricted stock awards, including restricted stock units. We also have an employee stock purchase plan for all eligible employees. The fair value of share-based payment awards is expensed straight-line over the requisite service period, which is generally the vesting period, for the entire award. Additionally, any modification of an award that increases its fair value will require us to recognize additional expense.

The fair value of our stock option grants and purchase rights under our employee stock purchase plan are estimated as of the grant date using the Black-Scholes option pricing model which is affected by our estimates of the risk free interest rate, our expected dividend yield, expected term and the expected share price volatility of our common shares over the expected term. The fair value of our restricted stock awards are based on the market value of our stock on the date of grant.

Research and Development

Costs associated with research and development activities are expensed as incurred, except for items with alternate future uses which are capitalized and depreciated over their estimated useful lives.

On occasion, we enter into co-development arrangements with current or prospective customers to defray a portion of the research and development expenses we expect to incur in connection with our development of an IC product. As amounts become due and payable, they are offset against research and development expense on a pro-rata basis.

Income Taxes

We account for income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between financial statement carrying amounts and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We establish a valuation allowance to reduce deferred tax assets if it is "more likely than not" that a portion or all of the asset will not be realized in future tax returns.

An uncertain tax position represents treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for financial reporting purposes. Until these positions are sustained by the taxing authorities, we do not recognize the tax benefits resulting from such positions and report the tax effects for uncertain tax positions in our consolidated balance sheets.

60

Risks and Uncertainties

Concentration of Suppliers

We do not own or operate a semiconductor fabrication facility and do not have the resources to manufacture our products internally. We rely on a limited number of foundries and assembly and test vendors to produce all of our wafers and for completion of finished products. We do not have any long-term agreements with any of these suppliers. In light of these dependencies, it is reasonably possible that failure to perform by one of these suppliers could have a severe impact on our results of operations. Additionally, the concentration of these vendors within Taiwan and the People’s Republic of China increases our risk of supply disruption due to natural disasters, economic instability, political unrest or other regional disturbances.

Risk of Technological Change

The markets in which we compete, or seek to compete, are subject to rapid technological change, frequent new product introductions, changing customer requirements for new products and features, and evolving industry standards. The introduction of new technologies and the emergence of new industry standards could render our products less desirable or obsolete, which could harm our business.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist of cash equivalents and accounts receivable. We limit our exposure to credit risk associated with cash equivalent balances by holding our funds in high quality, highly liquid money market accounts. We limit our exposure to credit risk associated with accounts receivable by carefully evaluating creditworthiness before offering terms to customers.

Recent Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2019-12, Simplifying the Accounting for Income Taxes ("ASU 2019-12"). ASU 2019-12 removes certain exceptions to the general principles in Accounting Standards Codification ("ASC") 740 and also clarifies and amends existing guidance to provide for more consistent application. ASU 2019-12 became effective for us in the first quarter of fiscal 2021, and early adoption is permitted. The adoption of ASU 2019-12 did not have a material impact on our financial position, results of operations and cash flows.

In November 2018, the FASB issued Accounting Standards Update No. 2018-18, Collaborative Arrangements: Clarifying the Interaction Between Topic 808 and Topic 606 ("ASU 2018-18"). ASU 2018-18 requires transactions in collaborative arrangements to be accounted for under ASC 606 if the counterparty is a customer for a good or service (or bundle of goods and services) that is a distinct unit of account. The amendment also precludes entities from presenting consideration from transactions with a collaborator that is not a customer together with revenue recognized from contracts with customers. ASU 2018-18 became effective for us on January 1, 2020. The adoption of ASU 2018-18 did not have a material impact on our financial position, results of operations and cash flows.

Short-Term Line of Credit

On December 21, 2010, we entered into a Loan and Security Agreement with Silicon Valley Bank (the "Bank"), which was amended over time, including as recently as December 14, 2020 (as amended, the "Revolving Loan Agreement"). The Revolving Loan Agreement provided a secured working capital-based revolving line of credit (the "Revolving Line") in an aggregate amount of up to the lesser of (i) $10,000, or (ii) $2,500 plus 80% of eligible domestic accounts receivable and certain foreign accounts receivable. The Revolving Line had a maturity date of March 26, 2021. In addition, the Revolving Loan Agreement provided for non-formula advances of up to $10,000 which could be made solely during the last five business days of any fiscal month or quarter and which were required to be repaid by the Company on or before the fifth business day after the applicable fiscal month or quarter end.

The Revolving Loan Agreement, as amended, contained customary affirmative and negative covenants as well as customary events of default. The occurrence of an event of default could have resulted in the acceleration of our obligations under the Revolving Loan Agreement, as amended, and an increase to the applicable interest rate, and would have permitted the Bank to exercise remedies with respect to its security interest. The Revolving Line had a maturity date of March 26, 2021. We did not renew the Revolving Loan Agreement upon its maturity.

As of December 31, 2020, we had no outstanding borrowings on the Revolving Line. 

Paycheck Protection Program Loan

On April 25, 2020, we entered into a loan with Silicon Valley Bank as the lender in an aggregate principal amount of $796 (the “Loan”) pursuant to the Paycheck Protection Program (the “PPP”) under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”).

The Loan was evidenced by a promissory note (the “Note”) dated April 25, 2020, and matured 2 years from the disbursement date. The Note bore interest at a rate of 1.000% per annum, with the first six months of interest deferred. Principal and interest

64

were payable monthly commencing 6 months after the disbursement date and could be prepaid by the Company at any time prior to maturity with no prepayment penalties. The Note contained customary events of default relating to, among other things, payment defaults or breaches of the terms of the Note. Upon the occurrence of an event of default, the Lender could require immediate repayment of all amounts outstanding under the Note.

Under the terms of the CARES Act, PPP loan recipients can apply for and be granted forgiveness for all or a portion of loans granted under the PPP. The Loan is subject to forgiveness to the extent proceeds are used for payroll costs, including payments required to continue group health care benefits, and certain rent, utility, and mortgage interest expenses (collectively, “Qualifying Expenses”), pursuant to the terms and limitations of the PPP. We used the Loan amount for Qualifying Expenses. During the fourth quarter of 2020, we applied for and received full forgiveness and recorded a gain of $796 within other income in our consolidated statements of operations.

NOTE 4.     MARKETABLE SECURITIES AND FAIR VALUE MEASUREMENTS

Marketable Securities

We had no marketable securities as of December 31, 2021. As of December 31, 2020, all of our marketable securities were classified as available-for-sale, had contractual maturities of one year or less and consisted of the following:

	Cost		Unrealized Gain (Loss)		Fair Value
Short-term marketable securities:
As of December 31, 2020:
Corporate debt securities	$	253	$	(3)	$	250
	$	253	$	(3)	$	250

Unrealized holding gains and losses are recorded in accumulated other comprehensive income, a component of shareholders’ equity, in the consolidated balance sheets.

65

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Three levels of inputs may be used to measure fair value:

Level 1:Valuations based on quoted prices in active markets for identical assets and liabilities.

Level 2:Valuations based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3:Valuations based on unobservable inputs in which there is little or no market data available, which require the reporting entity to develop its own assumptions.

The following table presents information about our assets and liabilities measured at fair value on a recurring basis in the consolidated balance sheets as of December 31, 2021 and 2020: 

	Level 1		Level 2		Level 3		Total
As of December 31, 2021:
Assets:
Cash equivalents:
Money market funds	$	15,254	$	—	$	—	$	15,254
As of December 31, 2020:
Assets:
Cash equivalents:
Money market funds	$	23,832	$	—	$	—	23,832
Short-term marketable securities:
Corporate debt securities	—		250		—		250

We primarily use the market approach to determine the fair value of our financial instruments. The fair value of our current assets and liabilities, including accounts receivable and accounts payable approximates the carrying value due to the short-term nature of these balances. We have currently chosen not to elect the fair value option for any items that are not already required to be measured at fair value in accordance with U.S. GAAP.

66

NOTE 5.     RESTRUCTURINGS

In August 2020, we executed a restructuring plan to make the operation of the Company more efficient (the "August 2020 Plan"). The August 2020 Plan included an approximately 14% reduction in workforce, primarily in the areas of operations, research and development, sales and marketing.

In January 2020, we executed a restructuring plan to make the operation of the Company more efficient (the "January 2020 Plan"). The January 2020 Plan included an approximately4% reduction in workforce, primarily in the areas of research and development and sales.

Total restructuring expense included in our statement of operations for the years ended December 31, 2021 and 2020 is comprised of the following:

	Year Ended December 31,
	2021		2020
Cost of revenue — restructuring:
Employee severance and benefits	$	—	$	173
	—		173
Operating expenses — restructuring:
Employee severance and benefits	$	—	$	2,041
	—		2,041
Total restructuring expense	$	—	$	2,214

The following is a rollforward of the accrued liabilities related to restructuring for the year ended December 31, 2021:

	Balance as of December 31, 2020		Expensed		Payments		Balance as of December 31, 2021
Employee severance and benefits	$	630	$	—	$	(630)	$	—
Accrued costs related to restructuring	$	630	$	—	$	(630)	$	—

NOTE 6.     LEASES

We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities in our consolidated balance sheets.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Operating lease ROU assets also exclude lease incentives received. For purposes of calculating operating lease liabilities, lease terms may be deemed to include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.

We have operating leases for office buildings and one vehicle. Our leases have remaining lease terms of 1 year to 6 years. Supplemental information related to lease expense and valuation of the ROU assets and lease liabilities was as follows:

	Year Ended			Year Ended
	December 31, 2021			December 31, 2020
Operating lease cost	$	2,622		$	2,721
Cash paid for amounts included in the measurement of lease liabilities:
Operating cash flows from operating leases	2,809			2,816
Leased assets obtained in exchange for new operating lease liabilities	629			3,535
Weighted average remaining lease term (in years)	2.95			3.76
Weighted average discount rate	4.96		%	4.99		%

67

Future minimum lease payments under non-cancellable leases as of December 31, 2021 were as follows:

Operating Lease Payments
Years ending December 31:
2022	$	2,652
2023	1,376
2024	877
2025	364
2026	364
Thereafter	91
Total operating lease payments	5,724
Less imputed interest	(432)
Total operating lease liabilities	$	5,292

As of December 31, 2021, the Company had no operating lease liabilities that had not commenced.

68

NOTE 7.     REVENUE

Revenue is recognized when control of the promised good or service is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our principal revenue generating activities consist of the following:

Product Sales - We sell integrated circuit products, also known as “chips” or “ICs”, based upon a customer purchase order, which includes a fixed price per unit. We have elected to account for shipping and handling as activities to fulfill the promise to transfer the goods, and not evaluate whether these activities are promised services to the customer. We generally satisfy our single performance obligation upon shipment of the goods to the customer and recognize revenue at a point in time upon shipment of the underlying product.

Our shipments are subject to limited return rights subject to our limited warranty for our products sold. In addition, we may provide other credits to certain customers pursuant to price protection and stock rotation rights, all of which are considered variable consideration when estimating the amount of revenue to recognize. We use the “most likely amount” method to determine the amount of consideration to which we are entitled. Our estimate of variable consideration is reassessed at the end of each reporting period based on changes in facts and circumstances. Historically, returns and credits have not been material.

Engineering Services - We enter into contracts for professional engineering services that include software development and customization. We identify each performance obligation in our engineering services agreements (“ESAs”) at contract inception. The ESA generally includes project deliverables specified by the customer. The performance obligations in the ESA are generally combined into one deliverable, with the pricing for services stated at a fixed amount. Services provided under the ESA generally result in the transfer of control over time. We recognize revenue on ESAs based on the proportion of labor hours expended to the total hours expected to complete the contract performance obligation. ESAs could include substantive customer acceptance provisions. In ESAs that include substantive customer acceptance provisions, we recognize revenue upon customer acceptance.

License Revenue - On occasion, we derive revenue from the license of our internally developed intellectual property ("IP"). Additionally, for certain IP license agreements, royalties are collected as customers sell their own products that incorporate our IP. IP licensing agreements that we enter into generally provide licensees the right to incorporate our IP components in their products with terms and conditions that vary by licensee. Fees under these agreements generally include license fees or royalty fees relating to our IP and support service fees, resulting in two performance obligations. We evaluate each performance obligation, which generally results in the transfer of control at a point in time for the license fee and over time for support services. Royalties are recognized as revenue is earned, generally when the customer sells its products that incorporate our IP.

Other - From time-to-time, we enter into arrangements for other revenue generating activities, such as providing technical support services to customers through technical support agreements. In each circumstance, we evaluate such arrangements for our performance obligations which generally results in the transfer of control for such services over time. Historically, such arrangements have not been material to our operating results.

The following table provides information about disaggregated revenue based on the preceding categories for the years ended December 31, 2021 and 2020:

	Year ended December 31,
	2021		2020
IC sales	$	50,807	$	39,205
Engineering services, license and other	4,295		1,650
Total revenues	$	55,102	$	40,855

For segment information, including revenue by geographic region, see "Note 14. Segment Information".

Our contract balances include accounts receivable, deferred revenue and our liability for warranty returns. For information concerning these contract balances, see "Note 3. Balance Sheet Components".

Payment terms and conditions for goods and services provided vary by contract; however, payment is generally required within 30 to 60 days of invoicing.

69

We have not identified any material costs incurred associated with obtaining a contract with a customer which would meet the criteria to be capitalized, therefore, these costs are expensed as incurred.

The aggregate amount of the transaction price allocated to unsatisfied performance obligations with an original expected duration of greater than one year is $30, which we expect to recognize ratably over the next 3 months.

NOTE 8.     INTEREST INCOME AND OTHER, NET

Interest income and other, consists of the following:

	Year Ended December 31,
	2021		2020
Other income	$	246	$	161
Interest income	211		87
Interest expense	—		(239)
Total interest income and other, net	$	457	$	9

NOTE 9.     RESEARCH AND DEVELOPMENT

During the third quarter of 2021, we entered into a best-efforts co-development agreement with a customer to defray a portion of the research and development expenses we expect to incur in connection with our development of an integrated circuit product. We expect our development costs to exceed the amounts received from the customer, and although we expect to sell units of the product to the customer, there is no commitment or agreement from the customer for such sales at this time. Additionally, we retain ownership of any modifications or improvements to our pre-existing intellectual property and may use such improvements in products sold to other customers.

Under the co-development agreement, $5,800 was payable by the customer within 60 days of the date of the agreement and three additional payments of $2,200, $1,300 and $1,300 are each payable upon completion of certain development milestones. As amounts become due and payable, they are offset against research and development expense on a pro rata basis. During the year ended December 31, 2021, we recognized an offset to research and development expense of $3,962.

NOTE 10.        INCOME TAXES

Current and Deferred Income Tax Expense

Domestic and foreign pre-tax loss is as follows:

	Year Ended December 31,
	2021		2020

Deferred Tax Assets, Liabilities and Valuation Allowance

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts for income tax purposes. Significant components of our deferred tax assets and liabilities are as follows: 

	December 31,
	2021		2020
Deferred tax assets:
Research and experimentation credit and deduction carryforwards	$	62,771	$	65,772
Net operating loss carryforwards	45,985		50,917
Depreciation and amortization	5,664		2,282
Deferred stock-based compensation	994		1,158
Reserves and accrued expenses	992		145
Foreign tax credit carryforwards	208		275

Total gross deferred tax assets	118,065		122,623
Deferred tax liabilities:
Other	(812)		(1,526)
Total gross deferred tax liabilities	(812)		(1,526)
Less valuation allowance	(116,372)		(120,981)
Net deferred tax assets	$	881	$	116

We continue to record a full valuation allowance against our U.S. net deferred tax assets as of December 31, 2021 and 2020, as it is not more likely than not that we will realize a benefit from these assets in a future period. In the third quarter of 2021, we recorded a valuation allowance against our net deferred tax assets in China in conjunction with the restructuring of our intercompany agreements and intellectual property. In the fourth quarter of 2021, we recognized $558 of our Canadian net deferred tax assets as we are more likely than not to realize a benefit from these assets in a future period. We have not provided a valuation allowance against our other foreign net deferred tax assets as we have concluded it is more likely than not that we will realize a benefit from these assets in a future period because our subsidiaries in these jurisdictions are cost-plus taxpayers. The net valuation allowance decreased $4,609 for the year ended December 31, 2021 and decreased $24 for the year ended December 31, 2020.

As of December 31, 2021, we had federal, state and foreign net operating loss carryforwards of $166,448, $6,756 and $39,450 respectively, which will begin to expire in 2022 with $31,705 of our federal net operating loss carryforward lasting indefinitely. As of December 31, 2021, we had available federal, state and foreign research and experimentation tax credit carryforwards of $7,823, $4,993, and $24,252 respectively. The federal and state tax credits will begin expiring in 2022 while the foreign credits have an indefinite life. In addition, our Canadian subsidiary has unclaimed scientific and experimental expenditures to be

71

carried forward and applied against future income in Canada of approximately $120,906. We have a general foreign tax credit of $118 which will begin to expire in 2022.

Our ability to utilize our federal net operating losses may be limited by Section 382 of the Internal Revenue Code of 1986, as amended, which imposes an annual limit on the ability of a corporation that undergoes an "ownership change" to use its net operating loss carryforwards to reduce its tax liability. An ownership change is generally defined as a greater than 50% increase in equity ownership by 5% shareholders in any three-year period.

We are not indefinitely reinvested in the earnings of our subsidiaries in Canada, Japan and Taiwan and have accrued tax on the future repatriation of cash for jurisdictions where withholding taxes would apply. We are no longer indefinitely reinvested in our China subsidiary and have reversed our previous accrual of $620 as a result of changes to our operating plan and implementation of our China intellectual property strategy.

Uncertain Tax Positions

We have recorded tax liabilities to address potential exposures involving positions that could be challenged by taxing authorities. As of December 31, 2021, the amount of our uncertain tax positions was a liability of $2,493 and a reduction to deferred tax assets of $1,254. As of December 31, 2020, the amount of our uncertain tax positions was a liability of $1,610 and a reduction to deferred tax assets of $1,189.

The following is a summary of the change in our liability for uncertain tax positions and interest and penalties: 

	2021		2020
Uncertain tax positions:
Balance at beginning of year	$	2,711	$	2,569
Accrual for positions taken in a prior year	825		24
Accrual for positions taken in current year	121		192
Reversals due to lapse of statute of limitations	(11)		(74)
Balance at end of year	$	3,646	$	2,711
Interest and penalties:
Balance at beginning of year	$	88	$	85
Accrual for positions taken in prior year	16		18
Accrual for positions taken in current year	—		—
Reversals due to lapse of statute of limitations	(3)		(15)
Balance at end of year	$	101	$	88

During the years ended December 31, 2021 and 2020 we recognized $16 and $18, respectively, of interest and penalties in income tax expense in our consolidated statements of operations.

We file income tax returns in the U.S. and various foreign jurisdictions. A number of years may elapse before an uncertain tax position is resolved by settlement or statute of limitations. Settlement of any particular position could require the use of cash. If the uncertain tax positions we have accrued for are sustained by the taxing authorities in our favor, the reduction of the liability will reduce our effective tax rate. We reasonably expect reductions in the liability for unrecognized tax benefits and interest and penalties of approximately $97 within the next twelve months due to the expiration of statutes of limitation in federal, state and foreign jurisdictions.

We are no longer subject to U.S. federal, state, and foreign examinations for years before 2018, 2017 and 2014, respectively. Our net operating loss and tax credit carryforwards from all years may be subject to adjustment for three years following the year in which utilized. We do not anticipate that any potential tax adjustments will have a significant impact on our financial position or results of operations.

We were not subject to, nor have we received any notice of, income tax examinations in any jurisdiction as of December 31, 2021.

NOTE 11.        COMMITMENTS AND CONTINGENCIES

Royalties

We license technology from third parties and have agreed to pay certain suppliers a royalty based on the number of chips sold or manufactured, the net sales price of the chips containing the licensed technology or a fixed non-cancelable fee. Royalty expense is recognized based on our estimated average unit cost for royalty contracts with non-cancelable prepayments and the stated contractual per unit rate for all other agreements. Royalty expense was $225 and $242 for the years ended December 31, 2021 and 2020, respectively, which is included in cost of revenue in our consolidated statements of operations.

401(k) Plan

We sponsor a 401(k) plan for eligible employees. Participants may defer a percentage of their annual compensation on a pre-tax basis, not to exceed the dollar limit that is set by law. A discretionary matching contribution by the Company is allowed and is equal to a uniform percentage of the amount of salary reduction elected to be deferred, which percentage will be determined each year by the Company. We made contributions of $55 and $48 to the 401(k) plan during the years ended December 31, 2021 and 2020, respectively.

Software licenses

We acquire rights to use certain software engineer design tools under software licenses.

As of December 31, 2021, future minimum payments under non-cancelable software licenses are as follows: 

Year Ending December 31,	Software licenses
2022	$	1,133
2023	365
	1,498
Less: Interest component	(65)
Present value of minimum software license payments	1,433
Less: Current portion	(1,077)
Long-term portion of obligations	$	356

Other Contractual Obligation

As part of the Acquisition, we acquired debt associated with an agreement with the Government of Canada called Technology Partnerships Canada ("TPC"). As part of the TPC agreement, ViXS Systems Inc. was provided funding to assist in research and development expenses of which a portion was later required to be repaid because the conditions for repayment were met. The scheduled payments are made on a quarterly basis and end in January 2024. $504 and $499 are included in accrued liabilities and current portion of long-term liabilities in our consolidated balance sheet as of December 31, 2021 and 2020, respectively. $57 and $268 are included in long-term liabilities, net of current portion in our consolidated balance sheets as of December 31, 2021 and 2020, respectively.

Contract Manufacturers

In the normal course of business, we commit to purchase products from our contract manufacturers to be delivered within the next 90 days. In certain situations, should we cancel an order, we could be required to pay cancellation fees. Such obligations could impact our immediate results of operations but would not materially affect our business.

Indemnifications

Certain of our agreements include limited indemnification provisions for claims from third-parties relating to our intellectual property. It is not possible for us to predict the maximum potential amount of future payments or indemnification costs under these or similar agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. We have not made any payments under these agreements in the past, and as of December 31, 2021, we have not incurred any material liabilities arising from these indemnification obligations. In the future, however, such obligations could immediately impact our results of operations but are not expected to materially affect our business.

73

Legal Proceedings

We are subject to legal matters that arise from time to time in the ordinary course of our business. Although we currently believe that resolving such matters, individually or in the aggregate, will not have a material adverse effect on our financial position, our results of operations, or our cash flows, these matters are subject to inherent uncertainties and our view of these matters may change in the future.

NOTE 12.        EARNINGS PER SHARE

Basic earnings per share amounts are computed based on the weighted average number of common shares outstanding. Diluted weighted average shares outstanding include the weighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period.

The following schedule reconciles the computation of basic and diluted net loss per share (in thousands, except per share data):

	Year Ended December 31,
	2021		2020
Net loss	$	(19,412)	$	(26,529)
Less: Net income attributable to redeemable non-controlling interest	(409)		—
Less: Net income attributable to certain entities owned by employees	(198)		—
Net loss attributable to Pixelworks Inc. - for purposes of earnings per share calculation	$	(20,019)	$	(26,529)
Weighted average shares outstanding - basic and diluted	52,509		40,712
Net loss attributable to Pixelworks, Inc. per share - basic and diluted	$	(0.38)	$	(0.65)

Basic and diluted earnings (loss) per share was computed by dividing the net income (loss) by the weighted-average number of common shares outstanding for the period. The numerator adjustments include an allocation of PWSH income to the redeemable non-controlling interests and the employee owned entities. The equity interest associated with the employee-owned entities are considered participating securities at PWSH and will be allocated income, however, they are not required to fund losses, and therefore, no allocations of losses will be made to the employee owned entities in periods of loss at PWSH. Potentially dilutive common shares from employee equity incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options, the assumed vesting of outstanding restricted stock units, and the assumed issuance of common stock under the employee stock purchase plan.

The following shares were excluded from the calculation of diluted net loss per share as their effect would have been anti-dilutive (in thousands):

	Year Ended December 31,
	2021	2020
Employee equity incentive plans	3,832	4,148

Potentially dilutive common shares from employee equity incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options, the assumed vesting of outstanding restricted stock units, and the assumed issuance of common stock under the employee stock purchase plan.

NOTE 13.        SHAREHOLDERS’ EQUITY

Preferred Stock

The Company is authorized to issue 50,000,000 shares of preferred stock with a par value of $0.001 per share. The Board of Directors is authorized to fix or alter the rights, preferences, privileges and restrictions granted to, or imposed on, each series of preferred stock. There were no shares of preferred stock issued as of December 31, 2021 and 2020.

Equity Offering

On December 14, 2020, we completed the sale of 4,900,000 shares of common stock in an underwritten registered offering. On December 16, 2020, an additional 735,000 shares were issued pursuant to the 30-day over-allotment option exercised by the underwriter. With the over-allotment shares, a total of 5,635,000 shares of common stock were sold in the offering at a price to the public of $2.45 per share. Net proceeds to the Company, after deducting underwriting discounts, commissions, and other expenses, were approximately $12,743.

At the Market Offering

On June 5, 2020, we entered into a sales agreement (the "Sales Agreement") with Cowen and Company, LLC ("Cowen"), pursuant to which we may issue and sell shares of the Company's common stock, par value $0.001 per share, having an aggregate offering price of up to $25,000, from time to time, through an "at the market" equity offering program under which Cowen will act as sales agent. Under the Sales Agreement, Cowen may sell the shares by methods deemed to be an "at the market offering" as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended, including sales made by means of ordinary brokers’ transactions on the Nasdaq Global Market or on any other existing trading market for the common stock or otherwise at market prices prevailing at the time of sale, in block transactions, or as otherwise directed by the Company. We pay Cowen a commission equal to three percent (3.0%) of the gross sales proceeds of any common stock sold through Cowen under the Sales Agreement. The Sales Agreement may be terminated by us upon prior notice to Cowen or by Cowen upon prior notice to us, or at any time under certain circumstances, including but not limited to the occurrence of a material adverse change in the Company. We are not obligated to sell any shares under the Sales Agreement.

During the year ended December 31, 2020, we sold an aggregate of 1,747,466 shares of our common stock under this at the market offering, resulting in aggregate net proceeds to us of approximately $4,429.

During the year ended December 31, 2021, we sold an aggregate of 61,018 shares of our common stock under this at the market offering, resulting in aggregate net proceeds to us of approximately $321.

Employee Equity Incentive Plans

On May 23, 2006, our shareholders approved the adoption of the Pixelworks, Inc. 2006 Stock Incentive Plan (the "2006 Plan"). The 2006 Plan has since been amended and restated on certain occasions, most recently on May 10, 2021 when our shareholders approved an increase to the total number of authorized shares to 22,683,333 shares. As of December 31, 2021, 2,105,497 shares were available for grant under the 2006 Plan.

Stock Options

The contractual life of newly issued stock option awards is six years. Our new hire vesting schedule provides that each option becomes exercisable at a rate of 25% on the first anniversary date of the grant and 2.083% on the last day of every month thereafter for a total of 36 additional increments. Our merit vesting schedule provides that merit-type awards become exercisable monthly over a period of three years.

During the years ended December 31, 2021 and 2020 the total intrinsic value of options exercised was $445 and $28, respectively, for which no income tax benefit has been recorded because a full valuation allowance has been provided for our U.S. deferred tax assets. As of December 31, 2021, options outstanding had a total intrinsic value of $684.

Options outstanding that have vested and are expected to vest as of December 31, 2021 are as follows:

	Number of shares	Weighted average exercise price		Weighted average remaining contractual term	Aggregate intrinsic value
Vested	264,688	$	2.61	3.48	$	491

Restricted Stock

The 2006 Plan provides for the issuance of restricted stock, including restricted stock units. During the years ended December 31, 2021 and 2020 we granted 2,123,844 and 2,137,317 shares, respectively, of restricted stock with a weighted average grant date fair value of $3.70 and $3.42 per share, respectively.

The following is a summary of restricted stock activity:

Employee Stock Purchase Plans

On May 18, 2010, our shareholders approved the adoption of the 2010 Pixelworks, Inc. Employee Stock Purchase Plan (the "ESPP") for U.S. employees and for certain foreign subsidiary employees. The ESPP provides for separate offering periods commencing on February 1 and August 1, with the first offering period beginning August 1, 2010. Each offering period continues for a period of 18 months with purchases every six months. Each eligible employee may purchase up to 3,000 shares of stock on each purchase date, with a maximum annual purchase amount of $25. The purchase price is equal to 85% of the lesser of the fair market value of the shares on the offering date or on the purchase date. On May 15, 2020 the ESPP was amended when our shareholders approved an increase to the total number of shares of common stock reserved for issuance to 3,300,000. During the years ended December 31, 2021 and 2020, we issued 159,177 and 202,019 shares, respectively for proceeds of $411 and $529, respectively, under the ESPP.

Stock-Based Compensation Expense

The fair value of stock-based compensation was determined using the Black-Scholes option pricing model and the following weighted average assumptions:

	Year Ended December 31,
	2021		2020
Stock Option Plans:
Risk free interest rate	0	%	2.00	%
Expected dividend yield	0	%	0	%
Expected term (in years)	0		3.75
Volatility	0	%	64	%
Employee Stock Purchase Plan:
Risk free interest rate	0.12	%	0.79	%
Expected dividend yield	0	%	0	%
Expected term (in years)	1.17		1.05
Volatility	75	%	65	%

There were no options granted during the year ended December 31, 2021. The weighted average fair value of options granted during the year ended December 31, 2020 was $0.93. The risk free interest rate is estimated using an average of treasury bill interest rates. The expected dividend yield is zero as we have not paid any dividends to date and do not expect to pay dividends in the future. Expected volatility is estimated based on the historical volatility of our common stock over the expected term as this represents our best estimate of future volatility. The contractual life of newly issued stock options is six years, and we have elected to use the "simplified method" to estimate expected term. Under the simplified method, an option's expected term is calculated as the average of its vesting period and original contractual life. The expected term of ESPP purchase rights is based on the estimated weighted average time to purchase.

As of December 31, 2021, unrecognized stock-based compensation expense is $5,560, which is expected to be recognized as stock-based compensation expense over a weighted average period of 1.12 years.

NOTE 15.     REDEEMABLE NON-CONTROLLING INTEREST AND EQUITY INTEREST OF PWSH SOLD TO EMPLOYEES

During the third quarter of 2021, Pixelworks, Inc. and our subsidiary, PWSH, entered into a Capital Increase Agreement with certain private equity and strategic investors based in China (collectively, the “Investors”) and certain entities which collectively are owned by approximately 75% of the employees of PWSH and its subsidiaries (collectively, the “ESOP”). The ESOP entities do not qualify as Employee Share Ownership Programs under IRC 4975(e)(7), but function as a qualified ESOP and hold an equity ownership in trust for employees.

The Investors invested approximately $30,844 in exchange for a redeemable non-controlling equity interest of 10.45% of PWSH. The Investors will have a liquidation preference in PWSH, a right to co-sell their interest in PWSH along with the Company on the same terms and conditions as the Company, a right to participate on a pro rata basis in any future financing rounds of PWSH, and the Company’s agreement while it remains an owner of PWSH and for two (2) years thereafter to not compete with the business of PWSH, nor solicit or otherwise cause any of PWSH’s core employees or customers to end their relationship with PWSH. These rights all expire upon initial public offering on the STAR Market. Each Investor has the right to require PWSH to redeem the entire equity interest held by such Investor, at the original purchase price paid plus 3% annual interest, if PWSH does not consummate an initial public offering on the STAR Market on or before June 30, 2024. Based on this contingency, the initial carrying amount of the redeemable non-controlling interests was recorded at fair value on the date of issuance of PWSH equity interests, net of issuance costs and presented in temporary equity on the condensed consolidated balance sheets. The Company has elected to accrete changes in the redemption value of the redeemable non-controlling interests from the issuance date through the earliest redemption date of June 30, 2024 using the interest method. Because the redeemable non-controlling interest is denominated in RMB, it will be revalued to USD at the end of each reporting period, with the changes in carrying value attributable to foreign currency being reflected within accumulated other comprehensive loss on the condensed consolidated balance sheets.

The ESOP entities invested approximately $12,329 in exchange for a redeemable non-controlling equity interest representing 5.95% of PWSH, which includes a discount of 30% from the valuation paid by the Investors. Each of the ESOP entities has the right to require PWSH to redeem the entire equity interest held by such ESOP entities at the original purchase price paid plus 5% annual interest, if PWSH does not achieve its Listing on or before December 31, 2024. Because the ESOP entities are owned by employees of PWSH and its subsidiaries and employees are required to render service until either the initial public offering on the STAR Market or repurchase date, the equity interest owned by the ESOP entities will be accounted for under ASC 718 (Compensation - Stock Compensation). The initial carrying amount of the investment has been recorded as a long-term deposit liability on the condensed consolidated balance sheets as the initial public offering cannot be considered probable at this time. We will recognize the periodic interest component of the award as compensation expense and accrete the long-term deposit liability to its redemption value as of December 31, 2024. Because the long-term deposit liability is denominated in RMB and is considered a monetary liability as defined in ASC 255 (Changing Prices), it will be revalued to USD at the end of each reporting period, with the changes in carrying value recorded as foreign currency gain/loss in our condensed consolidated statements of operations.

The process of going public on the STAR Market includes several periods of review and is therefore a lengthy process. There can be no assurances that PWSH will complete the Listing by June 30, 2024, or at all. In the event Pixelworks, Inc. is required to redeem the entire equity interest held by the Investors or the ESOP entities, we may be required to seek additional capital in order to redeem their PWSH shares and there would be no assurances that such capital would be available on terms acceptable to us, if at all. Any redemptions could have a material adverse effect on our business, financial condition and results of operations. The listing of PWSH on China's STAR Market will not change our status as a U.S. public company.

The components of the change in redeemable non-controlling interests for the year ended December 31, 2021 are presented in the following table (in thousands):

Carrying Value of Redeemable NCI as of January 1, 2021	$	—
Increase in non-controlling interest due to issuance of stock	30,844
Closing costs incurred	(868)
Net income attributable to redeemable non-controlling interest	409
Effect of foreign currency translation attributable to redeemable non-controlling interest	520
Carrying Value of Redeemable NCI as of December 31, 2021	$	30,905

Disclosure Controls and Procedures

As of the end of the period covered by this report, we conducted an evaluation under the supervision and with the participation of our Chief Executive Officer (our Principal Executive Officer) and Chief Financial Officer (our Principal Accounting and Financial Officer) of our disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")). Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2021, our disclosure controls and procedures were effective to ensure that information required to be disclosed in our periodic reports filed or submitted under the Securities Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms, and (ii) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding disclosure.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining a system of internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"). All internal control systems, no matter how well designed, have inherent limitations.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, under the oversight of our Board of Directors, we evaluated the effectiveness of our internal control over financial reporting as of December 31, 2021, the last day of our fiscal year. This evaluation was based on the criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our assessment, management has concluded that our internal control over financial reporting was effective as of the end of the fiscal year to provide reasonable assurances regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with U.S. GAAP.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting for external purposes in accordance with U.S. GAAP. A company’s 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 the assets of the company;

•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

•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. Accordingly, even effective internal control over financial reporting can only provide reasonable assurance of achieving its control objectives.

Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021 has not been audited by the Company’s independent registered public accounting firm. Management’s report is not subject to attestation by the Company’s independent registered public accounting firm pursuant to the rules of the Securities and Exchange Commission that permit the Company to provide only management’s report in this Annual Report.

Changes in Internal Control Over Financial Reporting

There were no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the fourth quarter of 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

SIXTH AMENDED AND RESTATED ARTICLES OF INCORPORATION

OF

PIXELWORKS, INC.

Pursuant to the Oregon Business Corporation Act (ORS Chapter 60), Pixelworks, Inc. hereby adopts the following Sixth Amended and Restated Articles of Incorporation, which shall supersede the heretofore existing Fifth Restated Articles of Incorporation and all previous amendment and restatements thereof.

The name of the Corporation is Pixelworks, Inc.

ARTICLE 2.
SHARES AND RIGHTS THEREOF GENERALLY.

2.2Rights of Common Stock.  The shares of common stock have unlimited voting rights and are entitled to receive the net assets of the Corporation on dissolution, subject to rights of the Preferred Stock.

2.3Authority to Designate Series Preferred.  The Board of Directors is hereby authorized to fix or alter the rights, preferences, privileges and restrictions granted to or imposed upon additional series of Preferred Stock, and the number of shares constituting any such series and the designation thereof, or of any of them.  Subject to compliance with applicable protective voting rights or consent rights which have been or may be granted to the Preferred Stock or any series thereof herein, by law, or in Articles of Amendment adopted by the Board of Directors (“Protective Provisions”), but notwithstanding any other rights of the Preferred Stock or any series thereof, the rights, privileges, preferences and restrictions of any such additional series may be subordinated to, made pari passu with (including, without limitation, inclusion in provisions with respect to liquidation and acquisition preferences, redemption and/or approval of matters by vote or written consent), or made senior to any of those of any present or future class of series of Preferred or Common Stock.  Subject to compliance with applicable Protective Provisions, the Board of Directors is also authorized to increase or decrease the number of shares of any series, prior or subsequent to the issue of that series, but not below the number of shares of such series then outstanding.  In case the number of shares of any series shall be so decreased, the shares constituting such decrease shall resume the status which they had prior to the adoption of the resolution originally fixing the number of shares of such series.

ARTICLE 3.
DIRECTORS.

3.1Number of Directors.  The number of directors of the Corporation shall be not less than three nor more than twelve, and within such limits, the exact number shall be fixed and increased or decreased from time to time by resolution of the Board of Directors.

3.2Election of Directors.  If the number of directors is fixed by the Board of Directors at six or more, the directors shall be divided into three classes designated Class I, Class II and Class III, each class to be as nearly equal in number as possible.  At the next annual meeting of shareholders following that designation (“First Meeting”), directors of all three classes shall be elected.  The term of office of Class I directors shall expire at the first annual meeting of shareholders following their election.  The terms of Class II directors shall expire at the second annual meeting of shareholders following their election.  The terms of the Class III directors shall expire at the third annual meeting of shareholders following their election.  At each annual meeting of shareholders after the

Exhibit 3.1

First Meeting, each class of directors elected to succeed those directors whose terms expire shall be elected to serve for three-year terms and until their successors are elected and qualified, so that the term of one class of directors will expire each year.  When the number of directors is changed within the limits provided herein, any newly created directorships, or any decrease in directorships, shall be so apportioned among the classes as to make all classes as nearly equal as possible, provided that no decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent directors.

3.3Removal.  All or any number of the directors of the Corporation may be removed only for cause and at a meeting of shareholders called expressly for that purpose, by the vote of 75 percent of the votes then entitled to be cast for the election of directors.  Cause for removal shall be deemed to exist only if the director whose removal is proposed has engaged in criminal conduct or has engaged in fraudulent or dishonest conduct or gross abuse of authority or discretion with respect to the Corporation. At any meeting of shareholders at which one or more directors are removed, a majority of votes then entitled to be cast for the election of directors may fill any vacancy created by such removal.  If any vacancy created by removal of a director is not filled by the shareholders at the meeting at which the removal is effected, such vacancy may be filled by a majority vote of the remaining directors.

3.4Amendment of Article. The provisions of this Article3 may not be amended, altered, changed or repealed in any respect unless such action is approved by the affirmative vote of not less than 75 percent of the votes then entitled to be cast for election of directors.

ARTICLE 5.

5.2Advancement of Expenses.  Expenses incurred by a director or officer of the Corporation in defending a Proceeding shall in all cases be paid by the Corporation in advance of the final disposition of such Proceeding at the written request of such person, if the person:

5.5Amendments.  Any repeal of this Article 5 shall only be prospective and no repeal or modification hereof shall adversely affect the rights under this Article 5 in effect at the time of the alleged occurrence of any action or omission to act that is the cause of any Proceeding.

ARTICLE 6.

6.PARTICIPATION

(a)Enrollment. An Eligible Employee may become a participant in this Plan by completing a Subscription Agreement on a form approved by and in a manner prescribed by the Committee (or its delegate). To become

Exhibit 10.2

effective, a Subscription Agreement must be signed by the Eligible Employee and be filed with the Corporation at the time specified by the Committee, but in all cases prior to the start of the Offering Period with respect to which it is to become effective, and must set forth a whole percentage (or, if the Committee so provides, a stated amount) of the Eligible Employee’s Compensation to be credited to the Participant’s Account as Contributions each pay period.

(b)Contribution Limits. Notwithstanding the foregoing, a Participant may not elect to contribute less than one percent (1%) nor more than ten percent (10%) (or such other limit as the Committee may establish prior to the start of the applicable Offering Period) of his or her Compensation during any one pay period as Plan Contributions. The Committee also may prescribe other limits, rules or procedures for Contributions.

(c)Content and Duration of Subscription Agreements. Subscription Agreements shall contain the Eligible Employee’s authorization and consent to the Corporation’s withholding from his or her Compensation the amount of his or her Contributions. An Eligible Employee’s Subscription Agreement, and his or her participation election and withholding consent thereon, shall remain valid for all Offering Periods until (1) the Eligible Employee’s participation terminates pursuant to the terms hereof, (2) the Eligible Employee files a new Subscription Agreement that becomes effective, or (3) the Committee requires that a new Subscription Agreement be executed and filed with the Corporation.

7.METHOD OF PAYMENT OF CONTRIBUTIONS

(a)Participation Accounts. The Corporation shall maintain on its books, or cause to be maintained by a recordkeeper, an Account in the name of each Participant. The percentage of Compensation elected to be applied as Contributions by a Participant shall be deducted from such Participant’s Compensation on each payday during the period for payroll deductions set forth below and such payroll deductions shall be credited to that Participant’s Account as soon as administratively practicable after such date. A Participant may not make any additional payments to his or her Account. A Participant’s Account shall be reduced by any amounts used to pay the Option Price of shares acquired, or by any other amounts distributed pursuant to the terms hereof.

(b)Payroll Deductions. Subject to such other rules as the Committee may adopt, payroll deductions with respect to an Offering Period shall commence as of the first day of the payroll period which coincides with or immediately follows the applicable Grant Date and shall end on the last date of the payroll period which coincides with or immediately precedes the applicable Purchase Date, unless sooner terminated by the Participant as provided in Section 7(d) or until his or her participation terminates pursuant to Section 11.

(c)Changes in Contribution Elections for Next Purchase Period. A Participant may discontinue, increase, or decrease the level of his or her Contributions (within the Plan limits) by completing and filing with the Corporation, on such terms as the Committee (or its delegate) may prescribe, a new Subscription Agreement which indicates such election. Subject to any other timing requirements that the Committee may impose, an election pursuant to this Section 7(c) shall be effective with the first Purchase Period that commences after the Corporation’s receipt of such election. Except as contemplated by Section 7(d) and 7(e), changes in Contribution levels may not take effect during a Purchase Period. Other modifications or suspensions of Subscription Agreements are not permitted.

(d)Withdrawal During an Offering Period. A Participant may terminate his or her Contributions during an Offering Period (and receive a distribution of the balance of his or her Account in accordance with Section 11) by completing and filing with the Corporation, in such form and on such terms as the Committee (or its delegate) may prescribe, a written withdrawal form which shall be signed by the Participant. Such termination shall be effective as soon as administratively practicable after its receipt by the Corporation. A withdrawal election pursuant to this Section 7(d) with respect to an Offering Period shall only be effective for a particular Purchase Period, however, if it is received by the Corporation prior to the Purchase Date of that Purchase Period (or such earlier deadline that the Committee may reasonably require to process the withdrawal prior to the applicable Purchase Date). Partial withdrawals of Accounts are not permitted.

(e)Discontinuance of Contributions During a Purchase Period. A Participant may discontinue his or her Contributions at any time during a Purchase Period by completing and filing with the Corporation, on such

Exhibit 10.2

terms as the Committee (or its delegate) may prescribe, a new Subscription Agreement which indicates such election. If a Participant elects to discontinue his or her Contributions pursuant to this Section 7(e), the Contributions previously credited to the Participant’s Account for that Purchase Period shall be used to exercise the Participant’s Option as of the applicable Purchase Date in accordance with Section 9 (unless the Participant makes a timely withdrawal election in accordance with Section 7(d), in which case such Participant’s Account shall be paid to him or her in cash in accordance with Section 11(a)).

(f)Leaves of Absence. During leaves of absence approved by the Corporation or a Participating Subsidiary and meeting the requirements of Regulation Section 1.421-1(h)(2) under the Code, a Participant may continue participation in this Plan by cash payments to the Corporation on his normal paydays equal to the reduction in his Plan Contributions caused by his leave.

8.GRANT OF OPTION

(a)Grant Date; Number of Shares. On each Grant Date, each Eligible Employee who is a Participant during that Offering Period shall be granted an Option to purchase a number of shares of Common Stock. The Option shall be exercised on each Purchase Date that occurs during that Offering Period. The number of shares of Common Stock to be purchased upon exercise of the Option on each Purchase Date shall be determined by dividing the Participant’s Account balance as of that Purchase Date by the Option Price, subject to the limits of Section 8(c).

(b)Option Price. The Option Price per share of the shares subject to an Option for a Purchase Period shall be the lesser of: (i) 85% of the Fair Market Value of a Share on the Grant Date of the Offering Period to which the Purchase Period relates; or (ii) 85% of the Fair Market Value of a Share on the Purchase Date of that Purchase Period; provided, however, that the Committee may provide prior to the start of any Purchase Period that the Option Price for that Purchase Period shall be determined by applying a discount amount (not to exceed 15%) to either (1) the Fair Market Value of a share of Common Stock on the Grant Date of the Offering Period to which the Purchase Period relates, or (2) the Fair Market Value of a share of Common Stock on the Purchase Date of that Purchase Period, or (3) the lesser of the Fair Market Value of a share of Common Stock on the Grant Date of the Offering Period to which the Purchase Period relates or the Fair Market Value of a share of Common Stock on the Purchase Date of that Purchase Period. Notwithstanding anything to the contrary in the preceding provisions of this Section 8(b), in no event shall the Option Price per share be less than the par value of a share of Common Stock.

(c)Limits on Share Purchases. Notwithstanding anything else contained herein, the maximum number of shares subject to an Option for an Offering Period shall be subject to the Individual Limit in effect on the Grant Date of that Offering Period (subject to adjustment pursuant to Section 17) and any person who is otherwise an Eligible Employee shall not be granted any Option (or any Option granted shall be subject to compliance with the following limitations) or other right to purchase shares under this Plan to the extent:

(1)    it would, if exercised, cause the person to own stock (within the meaning of Section 423(b)(3) of the Code) possessing 5% or more of the total combined voting power or value of all classes of stock of the Corporation, or of any Parent, or of any Subsidiary; or

(2)    such Option causes such individual to have rights to purchase stock under this Plan and any other plan of the Corporation, any Parent, or any Subsidiary which is qualified under Section 423 of the Code which accrue at a rate which exceeds $25,000 of the fair market value of the stock of the Corporation, of any Parent, or of any Subsidiary (determined at the time the right to purchase such stock is granted, before giving effect to any discounted purchase price under any such plan) for each calendar year in which such right is outstanding at any time.

For purposes of the foregoing, a right to purchase stock accrues when it first become exercisable during the calendar year. In determining whether the stock ownership of an Eligible Employee equals or exceeds the 5% limit set forth above, the rules of Section 424(d) of the Code (relating to attribution of stock ownership) shall

Exhibit 10.2

apply, and stock which the Eligible Employee may purchase under outstanding options shall be treated as stock owned by the Eligible Employee.

9.EXERCISE OF OPTION

(a)Purchase of Shares. Unless a Participant withdraws pursuant to Section 7(d) or the Participant’s Plan participation is terminated as provided in Section 11, his or her Option for the purchase of shares shall be exercised automatically on each Purchase Date for that Offering Period, without any further action on the Participant’s part, and the maximum number of whole shares of Common Stock subject to such Option (subject to the limits of Section 8(c)) shall be purchased at the Option Price with the balance of such Participant’s Account.

(b)Account Balance Remaining After Purchase. If any amount which is not sufficient to purchase a whole share remains in a Participant’s Account after the exercise of his or her Option on the Purchase Date: (1) such amount shall be credited to such Participant’s Account for the next Purchase Period, if he or she is then a Participant; or (2) if such Participant is not a Participant in the next Purchase Period, or if the Committee so elects, such amount shall be refunded to such Participant as soon as administratively practicable after such date. If the share limit of Section 4(a) is reached, any amount that remains in a Participant’s Account after the exercise of his or her Option on the Purchase Date to purchase the number of shares that he or she is allocated shall be refunded to the Participant as soon as administratively practicable after such date. If any amount which exceeds the limits of Section 8(c)(1) remains in a Participant’s Account after the exercise of his or her Option on the Purchase Date, such amount shall be refunded to the Participant as soon as administratively practicable after such date. The Participant’s Account shall be reduced on a dollar-for-dollar basis by any amount used to purchase shares hereunder or any amount refunded to the Participant.

10.DELIVERY OF SHARES

As soon as administratively practicable after the Purchase Date, the Corporation shall, in its discretion, either deliver to each Participant a certificate representing the shares of Common Stock purchased upon exercise of his or her Option, provide for the crediting of such shares in book entry form in the name of the Participant, or provide for an alternative arrangement for the delivery of such shares to a broker or recordkeeping service for the benefit of the Participant. In the event the Corporation is required to obtain from any commission or agency authority to issue any such certificate or otherwise deliver such shares, the Corporation will seek to obtain such authority. If the Corporation is unable to obtain from any such commission or agency authority which counsel for the Corporation deems necessary for the lawful issuance of any such certificate or other delivery of such shares, or if for any other reason the Corporation cannot issue or deliver shares of Common Stock and satisfy Section 21, the Corporation shall be relieved from liability to any Participant except that the Corporation shall return to each Participant to whom such shares cannot be issued or delivered the amount of the balance credited to his or her Account that would have otherwise been used for the purchase of such shares.

11.TERMINATION OF EMPLOYMENT; CHANGE IN ELIGIBLE STATUS

(a)General. Except as provided in Section 11(b) below, if a Participant ceases to be an Eligible Employee for any reason (including, without limitation, due to the Participant’s death, disability, quit, resignation or retirement, or due to a layoff or other termination of employment with or without cause), or if the Participant elects to withdraw from the Plan pursuant to Section 7(d), at any time prior to the last day of an Offering Period in which he or she participates, such Participant’s Account shall be paid to him or her (or, in the event of the Participant’s death, to the person or persons entitled thereto under Section 13) in cash, and such Participant’s Option and participation in the Plan shall automatically terminate as of the time that the Participant ceased to be an Eligible Employee.

(b)Change in Eligible Status; Leave. If a Participant (1) ceases to be an Eligible Employee during a Purchase Period but remains an employee of the Corporation or a Subsidiary through the Purchase Date for that Purchase Period (for example, and without limitation, due to a change in the Participant’s employer from the

Exhibit 10.2

Corporation or a Participating Subsidiary to a non-Participating Subsidiary, if the Participant’s employer ceases to maintain the Plan as a Participating Subsidiary but otherwise continues as a Subsidiary, or if the Participant’s customary level of employment no longer satisfies the requirements set forth in the definition of Eligible Employee), or (2) during a Purchase Period commences a sick leave, military leave, or other leave of absence approved by the Corporation or a Participating Subsidiary, and the leave meets the requirements of Treasury Regulation Section 1.421-1(h)(2) and the Participant is an employee of the Corporation or a Subsidiary or on such leave as of the applicable Purchase Date, such Participant’s Contributions shall cease (subject to Section 7(d) and Section 7(f)), and the Contributions previously credited to the Participant’s Account for that Purchase Period shall be used to exercise the Participant’s Option as of the applicable Purchase Date in accordance with Section 9 (unless the Participant makes a timely withdrawal election in accordance with Section 7(d), in which case such Participant’s Account shall be paid to him or her in cash in accordance with Section 11(a)).

(c)Re-Enrollment. A Participant’s termination from Plan participation precludes the Participant from again participating in this Plan during that Offering Period. However, such termination shall not have any effect upon his or her ability to participate in any succeeding Offering Period, provided that the applicable eligibility and participation requirements are again then met. A Participant’s termination from Plan participation shall be deemed to be a revocation of that Participant’s Subscription Agreement and such Participant must file a new Subscription Agreement to resume Plan participation in any succeeding Offering Period.

(d)Change in Subsidiary Status. For purposes of this Plan, if a Subsidiary ceases to be a Subsidiary, each person employed by that Subsidiary will be deemed to have terminated employment for purposes of this Plan, unless the person continues as an employee of the Corporation or another Subsidiary.

(f)Delegation. The Committee may delegate ministerial, non-discretionary functions to individuals who are officers or employees of the Corporation or a Subsidiary.

13.DESIGNATION OF BENEFICIARY

If the Committee permits beneficiary designations with respect to this Plan, then each Participant may file, on a form and in a manner prescribed by the Committee (or its delegate), a written designation of a beneficiary who is to receive any shares or cash from or with respect to such Participant’s Account under this Plan in the event of such Participant’s death. If a Participant is married and the designated beneficiary is not solely his or her spouse, spousal consent shall be required for such designation to be effective unless it is established (to the satisfaction of the Committee or its delegate) that there is no spouse or that the spouse cannot be located. The Committee may rely on the last designation of a beneficiary filed by a Participant in accordance with this Plan. Beneficiary designations may be changed by the Participant (and his or her spouse, if required) at any time on forms provided and in the manner prescribed by the Committee (or its delegate).

If a Participant dies with no validly designated beneficiary under this Plan who is living at the time of such Participant’s death (or in the event the Committee does not permit beneficiary designations under this Plan), the Corporation shall deliver all shares and/or cash payable pursuant to the terms hereof to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed, the Corporation, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Corporation, then to such other person as the Corporation may designate.

If a Participant’s death occurs before the end of an Offering Period or subsequent to the end of an Offering Period but prior to the delivery to him or her or for his or her benefit of any shares deliverable under the terms of this Plan, and the Corporation has notice of the Participant’s death, then any shares purchased for that Offering Period and any remaining balance of such Participant’s Account shall be paid to such beneficiary (or such other person entitled to such payment pursuant to this Section 13). If the Committee permits beneficiary designations with respect to this Plan, any such designation shall have no effect with respect to shares purchased and actually delivered (or credited, as the case may be) to or for the benefit of the Participant.

14.TRANSFERABILITY

Neither Contributions credited to a Participant’s Account nor any Options or rights with respect to the exercise of Options or right to receive shares under this Plan may be anticipated, alienated, encumbered, assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution, or as provided in Section 13) by the Participant. Any such attempt at anticipation, alienation, encumbrance, assignment, transfer, pledge or other disposition shall be without effect and all amounts shall be paid and all shares shall be delivered in accordance with the provisions of this Plan. Amounts payable or shares deliverable pursuant to this Plan shall be paid or delivered only to (or credited in the name of, as the case may be) the Participant or, in the event of the Participant’s death, the Participant’s beneficiary pursuant to Section 13.

Exhibit 10.2

15.USE OF FUNDS; INTEREST

All Contributions received or held by the Corporation under this Plan will be included in the general assets of the Corporation and may be used for any corporate purpose. Notwithstanding anything else contained herein to the contrary, no interest will be paid to any Participant or credited to his or her Account under this Plan (in respect of Account balances, refunds of Account balances, or otherwise). Amounts payable under this Plan shall be payable in shares of Common Stock or from the general assets of the Corporation and, except for any shares that may be reserved on the books of the Corporation for issuance with respect to this Plan, no special or separate reserve, fund or deposit shall be made to assure payment of amounts that may be due with respect to this Plan.

16.REPORTS

Statements shall be provided (either electronically or in written form, as the Committee may provide from time to time) to Participants as soon as administratively practicable following each Purchase Date. Each Participant’s statement shall set forth, as of such Purchase Date, that Participant’s Account balance immediately prior to the exercise of his or her Option, the Option Price, the number of whole shares purchased and his or her remaining Account balance, if any.

17.ADJUSTMENTS OF AND CHANGES IN THE STOCK

Upon or in contemplation of any reclassification, recapitalization, stock split (including a stock split in the form of a stock dividend), or reverse stock split; any merger, combination, consolidation, or other reorganization; split-up, spin-off, or any similar extraordinary dividend distribution in respect of the Common Stock (whether in the form of securities or property); any exchange of Common Stock or other securities of the Corporation, or any similar, unusual or extraordinary corporate transaction in respect of the Common Stock; or a sale of substantially all the assets of the Corporation as an entirety occurs; then the Committee shall equitably and proportionately adjust (1) the number and type of shares or the number and type of other securities that thereafter may be made the subject of Options (including the specific maxima and numbers of shares set forth elsewhere in this Plan), (2) the number, amount and type of shares (or other securities or property) subject to any or all outstanding Options, (3) the Option Price of any or all outstanding Options, and/or (4) the securities, cash or other property deliverable upon exercise of any outstanding Options, in each case to the extent necessary to preserve (but not increase) the level of incentives intended by this Plan and the then-outstanding Options.

Upon the occurrence of any event described in the preceding paragraph, or any other event in which the Corporation does not survive (or does not survive as a public company in respect of its Common Stock); then the Committee may make provision for a cash payment or for the substitution or exchange of any or all outstanding Options for cash, securities or property to be delivered to the holders of any or all outstanding Options based upon the distribution or consideration payable to holders of the Common Stock upon or in respect of such event.

The Committee may adopt such valuation methodologies for outstanding Options as it deems reasonable in the event of a cash or property settlement and, without limitation on other methodologies, may base such settlement solely upon the excess (if any) of the amount payable upon or in respect of such event over the Option Price of the Option.

In any of such events, the Committee may take such action sufficiently prior to such event to the extent that the Committee deems the action necessary to permit the Participant to realize the benefits intended to be conveyed with respect to the underlying shares in the same manner as is or will be available to shareholders generally.

18.POSSIBLE EARLY TERMINATION OF PLAN AND OPTIONS

Upon a dissolution or liquidation of the Corporation, or any other event described in Section 17 that the Corporation does not survive or does not survive as a publicly-traded company in respect of its Common Stock, as the case may be, this Plan and, if prior to the last day of an Offering Period, any outstanding Option granted with respect to that Offering Period shall terminate, subject to any provision that has been expressly made by the Board for the survival,

Exhibit 10.2

substitution, assumption, exchange or other settlement of this Plan and Options. In the event a Participant’s Option is terminated pursuant to this Section 18 without a provision having been made by the Board for a substitution, exchange or other settlement of the Option, such Participant’s Account shall be paid to him or her in cash without interest.

19.TERM OF PLAN; AMENDMENT OR TERMINATION

(a)Effective Date; Termination. Subject to Section 19(b), this Plan shall become effective as of the Effective Date. No new Offering Periods shall commence on or after the tenth anniversary of the Effective Date, and this Plan shall terminate as of the Purchase Date on or immediately following such date unless sooner terminated pursuant to Section 18 or this Section 19. In the event that during a particular Purchase Period all of the shares of Common Stock made available under this Plan are subscribed prior to the expiration of this Plan, this Plan and all outstanding Options hereunder shall terminate at the end of that Purchase Period and the shares available shall be allocated for purchase by Participants in that Purchase Period on a pro-rata basis determined with respect to Participants’ Account balances.

(b)Board Amendment Authority. The Board may, at any time, terminate or, from time to time, amend, modify or suspend this Plan, in whole or in part and without notice. Shareholder approval for any amendment or modification shall not be required, except to the extent required by law or applicable stock exchange rules, or required under Section 423 of the Code in order to preserve the intended tax consequences of this Plan. No Options may be granted during any suspension of this Plan or after the termination of this Plan, but the Committee will retain jurisdiction as to Options then outstanding in accordance with the terms of this Plan. No amendment, modification, or termination pursuant to this Section 19(b) shall, without written consent of the Participant, affect in any manner materially adverse to the Participant any rights or benefits of such Participant or obligations of the Corporation under any Option granted under this Plan prior to the effective date of such change. Changes contemplated by Section 17 or Section 18 shall not be deemed to constitute changes or amendments requiring Participant consent.

(c)Certain Additional Committee Authority. Notwithstanding the amendment provisions of Section 19(b) and without limiting the Board’s authority thereunder and without limiting the Committee’s authority pursuant to any other provision of this Plan, the Committee shall have the right (1) to designate from time to time the Subsidiaries whose employees may be eligible to participate in this Plan (including, without limitation, any Subsidiary that may first become such after the date shareholders first approve this Plan) (each a “Participating Subsidiary”), and (2) to change the service and other qualification requirements set forth under the definition of Eligible Employee in Section 2 (subject to the requirements of Section 423(b) of the Code and applicable rules and regulations thereunder). Any such change shall not take effect earlier than the first Purchase Period that starts on or after the effective date of such change. Any such change shall not require shareholder approval.

20.NOTICES

All notices or other communications by a Participant to the Corporation contemplated by this Plan shall be deemed to have been duly given when received in the form and manner specified by the Committee (or its delegate) at the location, or by the person, designated by the Committee (or its delegate) for that purpose.

21.CONDITIONS UPON ISSUANCE OF SHARES

This Plan, the granting of Options under this Plan and the offer, issuance and delivery of shares of Common Stock are subject to compliance with all applicable federal and state laws, rules and regulations (including but not limited to state and federal securities laws) and to such approvals by any listing, regulatory or governmental authority as may, in the opinion of counsel for the Corporation, be necessary or advisable in connection therewith. The person acquiring any securities under this Plan will, if requested by the Corporation and as a condition precedent to the exercise of his or her Option, provide such assurances and representations to the Corporation as the Committee may deem necessary or desirable to assure compliance with all applicable legal requirements.

Exhibit 10.2

22.PLAN CONSTRUCTION

(a)Section 16. It is the intent of the Corporation that transactions involving Options under this Plan (other than “Discretionary Transactions” as that term is defined in Rule 16b-3(b)(1) promulgated by the Commission under Section 16 of the Exchange Act, to the extent there are any Discretionary Transactions under this Plan), in the case of Participants who are or may be subject to the prohibitions of Section 16 of the Exchange Act, satisfy the requirements for exemption under Rule 16b-3(c) promulgated by the Commission under Section 16 of the Exchange Act to the maximum extent possible. Notwithstanding the foregoing, the Corporation shall have no liability to any Participant for Section 16 consequences of Options or other events with respect to this Plan.

(b)Section 423. Except as the Committee may expressly provide in the case of one or more sub-plans adopted pursuant to Section 12(b), this Plan and Options are intended to qualify under Section 423 of the Code. Accordingly, all Participants are to have the same rights and privileges (within the meaning of Section 423(b)(5) of the Code and except as not required thereunder to qualify this Plan under Section 423) under this Plan, subject to differences in Compensation among Participants and subject to the Contribution and share limits of this Plan.

(c)Interpretation. If any provision of this Plan or of any Option would otherwise frustrate or conflict with the intents expressed above, that provision to the extent possible shall be interpreted so as to avoid such conflict. If the conflict remains irreconcilable, the Committee may disregard the provision if it concludes that to do so furthers the interest of the Corporation and is consistent with the purposes of this Plan as to such persons in the circumstances.

23.EMPLOYEES’ RIGHTS

(a)No Employment Rights. Nothing in this Plan (or in any Subscription Agreement or other document related to this Plan) will confer upon any Eligible Employee or Participant any right to continue in the employ or other service of the Corporation or any Subsidiary, constitute any contract or agreement of employment or other service or effect an employee’s status as an employee at will, nor shall interfere in any way with the right of the Corporation or any Subsidiary to change such person’s compensation or other benefits or to terminate his or her employment or other service, with or without cause. Nothing contained in this Section 23(a), however, is intended to adversely affect any express independent right of any such person under a separate employment or service contract other than a Subscription Agreement.

(b)No Rights to Assets of the Company. No Participant or other person will have any right, title or interest in any fund or in any specific asset (including shares of Common Stock) of the Corporation or any Subsidiary by reason of any Option hereunder. Neither the provisions of this Plan (or of any Subscription Agreement or other document related to this Plan), nor the creation or adoption of this Plan, nor any action taken pursuant to the provisions of this Plan will create, or be construed to create, a trust of any kind or a fiduciary relationship between the Corporation or any Subsidiary and any Participant, Beneficiary or other person. To the extent that a Participant, Beneficiary or other person acquires a right to receive payment pursuant to this Plan, such right will be no greater than the right of any unsecured general creditor of the Corporation.

(c)No Shareholder Rights. A Participant will not be entitled to any privilege of stock ownership as to any shares of Common Stock not actually delivered to and held of record by the Participant. No adjustment will be made for dividends or other rights as a shareholder for which a record date is prior to such date of delivery.

24.MISCELLANEOUS

(a)Governing Law. This Plan, the Options, Subscription Agreements and other documents related to this Plan shall be governed by, and construed in accordance with, the laws of the State of Oregon.

(b)Severability. If any provision shall be held by a court of competent jurisdiction to be invalid and unenforceable, the remaining provisions of this Plan shall continue in effect.

Exhibit 10.2

(c)Captions and Headings. Captions and headings are given to the sections of this Plan solely as a convenience to facilitate reference. Such captions and headings shall not be deemed in any way material or relevant to the construction of interpretation of this Plan or any provision hereof.

(d)No Effect on Other Plans or Corporate Authority. The adoption of this Plan shall not affect any other Corporation or Subsidiary compensation or incentive plans in effect. Nothing in this Plan will limit or be deemed to limit the authority of the Board or Committee (1) to establish any other forms of incentives or compensation for employees of the Corporation or any Subsidiary (with or without reference to the Common Stock), or (2) to grant or assume options (outside the scope of and in addition to those contemplated by this Plan) in connection with any proper corporate purpose; to the extent consistent with any other plan or authority. Benefits received by a Participant under an Option granted pursuant to this Plan shall not be deemed a part of the Participant’s compensation for purposes of the determination of benefits under any other employee welfare or benefit plans or arrangements, if any, provided by the Corporation or any Subsidiary, except where the Committee or the Board (or the Board of Directors of the Subsidiary that sponsors such plan or arrangement, as applicable) expressly otherwise provides or authorizes in writing.

25.TAX WITHHOLDING

Notwithstanding anything else contained in this Plan herein to the contrary, the Corporation may deduct from a Participant’s Account balance as of a Purchase Date, before the exercise of the Participant’s Option is given effect on such date, the amount of taxes (if any) which the Corporation reasonably determines it or any Subsidiary may be required to withhold with respect to such exercise. In such event, the maximum number of whole shares subject to such Option (subject to the other limits set forth in this Plan) shall be purchased at the Option Price with the balance of the Participant’s Account (after reduction for the tax withholding amount).

Should the Corporation for any reason be unable, or elect not to, satisfy its or any Subsidiary’s tax withholding obligations in the manner described in the preceding paragraph with respect to a Participant’s exercise of an Option, or should the Corporation or any Subsidiary reasonably determine that it or an affiliated entity has a tax withholding obligation with respect to a disposition of shares acquired pursuant to the exercise of an Option prior to satisfaction of the holding period requirements of Section 423 of the Code, the Corporation or Subsidiary, as the case may be, shall have the right at its option to (1) require the Participant to pay or provide for payment of the amount of any taxes which the Corporation or Subsidiary reasonably determines that it or any affiliate is required to withhold with respect to such event or (2) deduct from any amount otherwise payable to or for the account of the Participant the amount of any taxes which the Corporation or Subsidiary reasonably determines that it or any affiliate is required to withhold with respect to such event.

26.NOTICE OF SALE

Any person who has acquired shares under this Plan shall give prompt written notice to the Corporation of any sale or other transfer of the shares if such sale or transfer occurs (1) within the two-year period after the Grant Date of the Offering Period with respect to which such shares were acquired, or (2) within the twelve-month period after the Purchase Date of the Purchase Period with respect to which such shares were acquired.

(All share limits in the Plan are presented after giving effect to the Company's 1-for-3 stock split in June 2008.) The Shares may be authorized, but unissued, or reacquired Common Stock. Shares issued in respect of any “full-value award” granted under the Plan shall be counted against the foregoing share limit for the Plan as 1.33 shares for every one share issued in connection with such award. (For example, if a stock bonus of 100 shares of Common Stock is granted

under the Plan, 133 shares shall be charged against the share limit in connection with that award.) For this purpose, a “full-value award” means any Award under the Plan that is not an Option or SAR.

3.2. If an Option or SAR should expire, or become unexercisable for any reason, or is otherwise terminated or forfeited, without having been exercised in full, the Optioned Stock which was subject thereto shall, unless the Plan shall have been terminated, become available for future Option or SAR grants and/or Sales under the Plan. If any Shares issued pursuant to a Sale or exercise of an Option or SAR shall be reacquired, canceled or forfeited for any reason, such Shares shall become available for future Option or SAR grants and/or Sales under the Plan, unless the Plan shall have been terminated. If any reacquired, canceled or forfeited Shares were originally issued upon exercise of an Incentive Stock Option, then once so reacquired, canceled or forfeited, such Shares shall not be considered to have been issued for purposes of applying the limitation set forth in Section 3.3 below. Notwithstanding the foregoing, the following shares of Stock may not again be made available for issuance as awards under the Plan: (i) shares of Stock not issued or delivered as a result of the net settlement of an outstanding Option or SAR, (ii) shares of Stock used to pay the exercise price or withholding taxes related to an outstanding award, or (iii) shares of Stock repurchased on the open market with the proceeds of the exercise price of an Option.

3.3. Notwithstanding any other provision of this Section 3, but subject to the adjustment provisions of Section 11.1 of the Plan, the maximum number of Shares that may be issued upon the exercise of Incentive Stock Options shall be 22,683,333.

4. Administration of the Plan.

4.1. Procedure.

4.1.1. Multiple Administrative Committees. If permitted by Rule 16b-3, the Plan may be administered by different Committees with respect to Directors, Officers who are not Directors, and Employees who are neither Directors nor Officers.

4.1.2. Administration With Respect to Directors and Officers Subject to Section 16(b). With respect to Award grants to Employees who are also Officers or Directors subject to Section 16(b) of the Exchange Act, the Plan shall be administered by (A) the Board, if the Board may administer the Plan in compliance with the rules governing a plan intended to qualify as a discretionary plan under Rule 16b-3, or (B) a Committee designated by the Board to administer the Plan, which Committee shall be constituted to comply with the rules, if any, governing a plan intended to qualify as a discretionary plan under Rule 16b-3. Once appointed, such Committee shall continue to serve in its designated capacity until otherwise directed by the Board. From time to time the Board may increase the size of the Committee and appoint additional members, remove members (with or without cause) and substitute new members, fill vacancies (however caused), and remove all members of the Committee and thereafter directly administer the Plan, all to the extent permitted by the rules, if any, governing a plan intended to qualify as a discretionary plan under Rule 16b-3. With respect to persons subject to Section 16 of the Exchange Act, transactions under the Plan are intended to comply with all applicable conditions of Rule 16b-3. To the extent any provision of the Plan or action by the Administrator fails to so comply, it shall be deemed null and void, to the extent permitted by law and deemed advisable by the Administrator.

4.1.3. Administration With Respect to Other Persons. With respect to Award grants to Employees or Consultants who are neither Directors nor Officers of the Company, the Plan shall be administered by the Board or a Committee designated by the Board, which Committee shall be constituted to satisfy the legal requirements relating to the administration of stock option plans under applicable corporate and securities laws and the Code. Once appointed, such Committee shall serve in its designated capacity until otherwise directed by the Board. The Board may increase the size of the Committee and appoint additional members, remove members (with or without

Exhibit 10.3

cause) and substitute new members, fill vacancies (however caused), and remove all members of the Committee and thereafter directly administer the Plan, all to the extent permitted by the legal requirements relating to the administration of stock option plans under state corporate and securities laws and the Code.

4.2. Powers of the Administrator. Subject to the provisions of the Plan, and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator shall have the authority, in its discretion:

4.2.1. to grant Awards or SARs;

4.2.2. to authorize Sales of Shares hereunder;

4.2.3. to determine, upon review of relevant information, the Fair Market Value of a Share;

4.2.4. to determine the exercise/purchase price per Share of Options or SARs to be granted or Shares to be Sold, which exercise/purchase price shall be determined in accordance with Section 8.1 of the Plan;

4.2.5. to determine the Employees or Consultants to whom, and the time or times at which, Options or SARs shall be granted and the number of Shares to be represented by each Option or SAR;

4.2.6. to determine the Employees or Consultants to whom, and the time or times at which, Shares shall be Sold and the number of Shares to be Sold;

4.2.7. to administer and interpret the Plan;

4.2.8. to prescribe, amend and rescind rules and regulations relating to the Plan;

4.2.9. to determine the terms and provisions of each Option or SAR granted (which need not be identical) and, with the consent of the holder thereof, modify or amend each Option or SAR;

4.2.10. to determine the terms and provisions of each Sale of Shares (which need not be identical) and, with the consent of the purchaser thereof, modify or amend each Sale;

4.2.11. to accelerate (with the consent of the Grantee) the exercise date of any Option;

4.2.12. to accelerate (with the consent of the Grantee or purchaser of Shares) the vesting restrictions applicable to Shares Sold or Options or SARs granted under the Plan;

4.2.13. to authorize any person to execute on behalf of the Company any instrument required to effectuate the grant of an Option, SAR or Sale of Shares previously granted or authorized by the Administrator;

4.2.14. to determine the transfer or vesting restrictions, repurchase rights or other restrictions applicable to Shares issued under the Plan;

4.2.16. to approve forms for use under the Plan; and

4.2.17. to make all other determinations deemed necessary or advisable for the administration of the Plan.

Notwithstanding any other provision herein, except in connection with a corporate transaction involving the Company (including, without limitation, any stock dividend, stock split, extraordinary cash dividend,

Exhibit 10.3

recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination, or exchange of shares), the terms of outstanding awards may not be amended to reduce the exercise price of outstanding Options or SARs or cancel outstanding Options or SARs in exchange for cash, other awards or Options or SARs with an exercise price that is less than the exercise price of the original Options or SARs without shareholder approval.

4.3. Effect of Administrator's Decision. All decisions, determinations and interpretations of the Administrator shall be final and binding on all Grantees and any other holders of any Shares Sold under the Plan.

5. Eligibility.

5.1. Persons Eligible. Awards may be granted only to Employees and Consultants. Incentive Stock Options may be granted only to Employees. An Employee or Consultant who has been granted an Award may, if he or she is otherwise eligible, be granted additional Awards.

5.2. ISO Limitation. To the extent that the aggregate Fair Market Value of Shares subject to a Grantee's Incentive Stock Options granted by the Company, any Parent or Subsidiary which become exercisable for the first time during any calendar year (under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonqualified Stock Options. For purposes of this Section 5.2, Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares shall be determined as of the time of grant.

5.3. Section 5.2 Limitations. Section 5.2 of the Plan shall apply only to an Option evidenced by an Award Agreement which sets forth the intention of the Company and the Grantee that such Option shall qualify as an Incentive Stock Option. Section 5.2 of the Plan shall not apply to any Option evidenced by an Award Agreement which sets forth the intention of the Company and the Grantee that such Option shall be a Nonqualified Stock Option.

5.4. No Right to Continued Employment. The Plan shall not confer upon any Grantee any right with respect to continuation of employment or consulting relationship with the Company, nor shall it interfere in any way with his or her right or the Company's right to terminate their employment or consulting relationship at any time, with or without cause.

5.5. Other Limitations. The following limitations shall apply to grants of Options or SARs to Employees:

5.5.1. No Employee shall be granted, in any fiscal year of the Company, Options or SARs to acquire more than 250,000 Shares.

5.5.2. In connection with his or her initial employment, an Employee may be granted Options or SARs for up to an additional 250,000 Shares which shall not count against the limit set forth in subsection 5.5.1 above.

5.5.3. The foregoing limitations shall be adjusted proportionately in connection with any change in the Company's capitalization as described in Section 11.

6. Term of Plan. The Plan shall become effective upon the earlier to occur of its adoption by the Board or its approval by the shareholders of the Company as described in Section 17 of the Plan. It shall continue in effect for a term of ten (10) years, unless sooner terminated under Section 13 of the Plan. However, if the Company's shareholders approve an increase in the number of Shares available for issuance under section 3.1, such increase shall be deemed the adoption of a new plan with respect to the increased number of Shares, which may be issued for a term of ten (10) years following the date of such increase.

Exhibit 10.3

7. Term of Options and SARs. The term of each Option and SAR shall be stated in the Notice of Grant; provided, however, that in no event shall the term of any Option or SAR exceed six (6) years from the date of grant. However, in the case of an Incentive Stock Option granted to a Grantee who, on the date the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided in the Notice of Grant.

8. Exercise/Purchase Price and Consideration.

8.1. Exercise/Purchase Price. The per Share exercise/purchase price for the Shares to be issued pursuant to exercise of an Option or SAR or a Sale of Shares shall be such price as is determined by the Administrator, but shall be subject to the following:

8.1.1. In the case of an Incentive Stock Option

(1) granted to an Employee who, at the time of the grant of such Incentive Stock Option, owns more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be at least one hundred ten percent (110%) of the Fair Market Value on the date of the grant.

(2) granted to any other Employee, the per Share exercise price shall be at least one hundred percent (100%) of the Fair Market Value on the date of grant.

8.1.2. In the case of a Nonqualified Stock Option, SAR or Sale, the per Share exercise/purchase price shall be at least one hundred percent (100%) of the Fair Market Value on the date of grant or Sale, as the case may be.

8.2. Consideration. The consideration to be paid for the Shares to be issued upon exercise of an Option or pursuant to a Sale, including the method of payment, shall be determined by the Administrator. In the case of an Incentive Stock Option, the Administrator shall determine the acceptable form of consideration at the time of grant. Such consideration may consist of:

8.2.1. cash;

8.2.2. check;

8.2.3. promissory note;

8.2.4. transfer to the Company of Shares which

(1) in the case of Shares acquired upon exercise of an Option, have been owned by the Grantee for more than six months on the date of transfer, and

(2) have a Fair Market Value on the date of transfer equal to the aggregate exercise price of the Shares to be acquired;

8.2.5. if and so long as the Common Stock is registered under Section 12(b) or 12(g) of the Exchange Act, delivery of a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company the amount of sale or loan proceeds required to pay the exercise price;

8.2.6. such other consideration and method of payment for the issuance of Shares to the extent permitted by legal requirements relating to the administration of stock option plans and issuances of capital stock under applicable corporate and securities laws and the Code; or

Exhibit 10.3

8.2.7. any combination of the foregoing methods of payment.

If the Fair Market Value of the number of whole Shares transferred or the number of whole Shares surrendered is less than the total exercise price of the Option, the shortfall must be made up in cash or by check. Notwithstanding the foregoing provisions of this Section 8.2, the consideration for Shares to be issued pursuant to a Sale may not include, in whole or in part, the consideration set forth in subsection 8.2.5 above.

9. Exercise of Option or SAR.

9.1. Procedure for Exercise; Rights as a Shareholder. Any Option or SAR granted hereunder shall be exercisable at such times and under such conditions as determined by the Administrator, including Performance Criteria with respect to the Company and/or the Grantee, and as shall be permissible under the terms of the Plan.

An Option or SAR may not be exercised for a fraction of a Share. If the exercise of a SAR would result in the issuance of a fractional Share, the Shares to be issued shall be rounded to the nearest whole Share.

An Option or SAR shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option or SAR by the Grantee and full payment for the Shares with respect to which the Option is exercised has been received by the Company. Full payment may, as authorized by the Administrator, consist of any consideration and method of payment allowable under the Award Agreement and Section 8.2 of the Plan. Each Grantee who exercises an Option or SAR shall, upon notification of the amount due (if any) and prior to or concurrent with delivery of the certificate representing the Shares, pay to the Company amounts necessary to satisfy applicable federal, state and local tax withholding requirements. A Grantee must also provide a duly executed copy of any stock transfer agreement then in effect and determined to be applicable by the Administrator. Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock represented by such stock certificate, notwithstanding the exercise of the Option or SAR. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 11 of the Plan. Subject to section 3, exercise of an Option or settlement of a SAR shall decrease the number of Shares thereafter available, both for purposes of the Plan and for issuance under the Option or SAR by the number of Shares issued upon such exercise.

9.2. Termination of Employment or Consulting Relationship. In the event that a Grantee's Continuous Status as an Employee or Consultant terminates (other than upon the Grantee's death or Disability), the Grantee may exercise his or her Option or SAR, but only within such period of time as is determined by the Administrator, and only to the extent that the Grantee was entitled to exercise it at the date of termination (but in no event later than the expiration of the term of such Option or SAR as set forth in the Notice of Grant). In the case of an Incentive Stock Option, the Administrator shall determine such period of time (in no event to exceed three (3) months from the date of termination) when the Option is granted. If, at the date of termination, the Grantee is not entitled to exercise his or her entire Option or SAR, the unexercisable portion of the Option or SAR shall, unless otherwise expressly provided by the Administrator, terminate on the date of such termination and the Shares covered by such portion shall revert to the Plan. If, after termination, the Grantee does not exercise the remaining portion of his or her Option or SAR within the time specified by the Administrator, such portion of the Option or SAR shall terminate, and the Shares covered by such portion shall revert to the Plan.

9.3. Disability of Grantee. In the event that a Grantee's Continuous Status as an Employee or Consultant terminates as a result of the Grantee's Disability, the Grantee may exercise his or her Option or SAR at any time within twelve (12) months from the date of such termination, but only to the extent that the Grantee was entitled to

Exhibit 10.3

exercise it at the date of such termination (but in no event later than the expiration of the term of such Option or SAR as set forth in the Notice of Grant). If, at the date of termination, the Grantee is not entitled to exercise his or her entire Option or SAR, the unexercisable portion of the Option or SAR shall, unless otherwise expressly provided by the Administrator, terminate on the date of such termination and the Shares covered by such portion shall revert to the Plan. If, after termination, the Grantee does not exercise the remaining portion of his or her Option or SAR within the time specified herein, such portion of the Option or SAR shall terminate, and the Shares covered by such portion shall revert to the Plan.

9.4. Death of Grantee. In the event of the death of a Grantee, the Option or SAR may be exercised at any time within twelve (12) months following the date of death (but in no event later than the expiration of the term of such Option or SAR as set forth in the Notice of Grant), by the Grantee's estate or by a person who acquired the right to exercise the Option or SAR by bequest or inheritance, but only to the extent that the Grantee was entitled to exercise the Option or SAR at the date of death. If, at the time of death, the Grantee was not entitled to exercise his or her entire Option or SAR, the unexercisable portion of the Option or SAR shall, unless otherwise expressly provided by the Administrator, terminate on the date of such termination and the Shares covered by such portion shall revert to the Plan. If, after death, the Grantee's estate or a person who acquired the right to exercise the Option or SAR by bequest or inheritance does not exercise the remaining portion of the Option or SAR within the time specified herein, such portion of the Option or SAR shall terminate, and the Shares covered by such portion shall revert to the Plan.

9.5. Rule 16b-3. Options or SARs, as well as Sales of Shares, granted to persons subject to Section 16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions.

10. Nontransferability of Awards. Except as otherwise specifically provided in the Award Agreement, an Award may not be sold, pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will, or by the laws of descent and distribution, and may be exercised during the lifetime of the Grantee only by the Grantee or, if incapacitated, by his or her legal guardian or legal representative.

11. Adjustments Upon Changes in Capitalization or Merger.

11.1. Changes in Capitalization. Subject to any required action by the shareholders of the Company, the number of shares of Common Stock covered by each outstanding Award and the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Awards have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Award, as well as the price per share of Common Stock covered by each such outstanding Award, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Administrator, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an Award.

Exhibit 10.3

11.2. Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, each outstanding Award will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Administrator. The Administrator may, in the exercise of its sole discretion in such instances, declare that any Award shall terminate as of a date fixed by the Board and, in the case of Options and SARs, give each Grantee the right to exercise Grantee's Option or SAR as to all or any part of the Optioned Stock subject to the Option or SAR, including Shares as to which the Option or SAR would not otherwise be exercisable.

11.3. Merger or Asset Sale. Except as otherwise provided in an Award Agreement, in the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each outstanding Award shall be assumed or an equivalent award shall be substituted by such successor corporation or a Parent or Subsidiary of such successor corporation, unless the Administrator determines, in the exercise of its sole discretion and in lieu of such assumption or substitution, that, in the case of Options and SARs, each Grantee shall have the right to exercise the Grantee's Options or SARs as to all or any part of the Optioned Stock subject to the Option or SAR, including Shares as to which the Option or SAR would not otherwise be exercisable. If the Administrator determines that an Option or SAR shall be exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Administrator shall notify the Grantee that the Option or SAR shall be so exercisable for a period of thirty (30) days from the date of such notice or such shorter period as the Administrator may specify in the notice, and the Option or SAR will terminate upon the expiration of such period. For the purposes of this paragraph, the Option or SAR shall be considered assumed or substituted if, following the merger or sale of assets, the Option or SAR confers the right to purchase, for each Share of Optioned Stock subject to the Option or SAR immediately prior to the merger or sale of assets, the consideration (whether stock, cash, or other securities or property) received in the merger or sale of assets by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the merger or sale of assets was not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Option or SAR, for each Share of Optioned Stock subject to the Option or SAR, to be solely common stock of the successor corporation or its Parent substantially equal in Fair Market Value to the per share consideration received by holders of Common Stock in the merger or sale of assets. The determination of such substantial equality of value of consideration shall be made by the Administrator and its determination shall be conclusive and binding.

12. Time of Granting Awards. The date of grant of an Award shall, for all purposes, be the date on which the Administrator makes the determination granting such Award (or such later date as the Administrator may establish at the time of granting the Award). Notice of the determination shall be given to each Grantee within a reasonable time after the date of such grant.

13. Amendment and Termination of the Plan.

13.1. Amendment and Termination. The Board may amend or terminate the Plan from time to time in such respects as the Board may deem advisable.

13.2. Shareholder Approval. The Company shall obtain shareholder approval of any Plan amendment to the extent necessary and desirable to comply with Rule 16b-3 or with Section 422 of the Code (or any successor rule or statute or other applicable law, rule or regulation, including the requirements of any exchange or quotation system on which the Common Stock is listed or quoted). Such shareholder approval, if required, shall be obtained in such a manner and to such a degree as is required by the applicable law, rule or regulation.

Exhibit 10.3

13.3. Effect of Amendment or Termination. Any such amendment or termination of the Plan shall not affect Awards already granted, and such Awards shall remain in full force and effect as if this Plan had not been amended or terminated, unless mutually agreed otherwise between the Grantee and the Administrator, which agreement must be in writing and signed by the Grantee and the Administrator.

14. Conditions Upon Issuance of Shares. Shares shall not be issued pursuant to the exercise of an Option, SAR or a Sale unless the exercise of such Option, SAR or consummation of the Sale and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, applicable state securities laws, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange (including Nasdaq) upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance.

15. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

16. Liability of Company.

16.1. Inability to Obtain Authority. Inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

As a condition to the exercise of an Option or SAR or a Sale, the Company may require the person exercising such Option or SAR or to whom Shares are being Sold to represent and warrant at the time of any such exercise or Sale that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned relevant provisions of law.

16.2. Grants Exceeding Allotted Shares. If the grant of an Award causes the aggregate number of Shares previously issued under the Plan and subject to then-outstanding Awards under the Plan to exceed, as of the date of grant, the number of Shares which may be issued under the Plan without additional shareholder approval, such Award shall be void with respect to such excess Shares, unless shareholder approval of an amendment sufficiently increasing the number of Shares subject to the Plan is timely obtained in accordance with Section 13 of the Plan.

17. Shareholder Approval. Continuance of the Plan shall be subject to approval by the shareholders of the Company within twelve (12) months before or after the date the Plan is adopted. Such shareholder approval shall be obtained in the manner and to the degree required under applicable federal and state law.

18. Tax Withholding. Upon any exercise, vesting, or payment of any Award, or upon the disposition of shares of Common Stock acquired pursuant to the exercise of an Incentive Stock Option prior to satisfaction of the holding period requirements of Section 422 of the Code, or upon any other tax withholding event with respect to any award, the Company or one of its Subsidiaries shall have the right at its option to:

(a) require the Grantee (or the Grantee's personal representative or beneficiary, as the case may be) to pay or provide for payment of at least the minimum amount of any taxes which the Company or one of its Subsidiaries may be required to withhold with respect to such Award event or payment; or

(b) deduct from any amount otherwise payable in cash (whether related to the Award or otherwise) to the Grantee (or the Grantee's personal representative or beneficiary, as the case may be) the minimum amount of any taxes which the Company or one of its Subsidiaries may be required to withhold with respect to such

Exhibit 10.3

Award event or payment, except to the extent additional withholding does not result in adverse accounting treatment to the Company.

In any case where a tax is required to be withheld in connection with the delivery of shares of Common Stock under the Plan, the Administrator may in its sole discretion (subject to Section 14) require or grant (either at the time of the Award or thereafter) to the Grantee the right to elect, pursuant to such rules and subject to such conditions as the Administrator may establish, that the Company reduce the number of shares to be delivered by (or otherwise reacquire) the appropriate number of shares, valued in a consistent manner at their Fair Market Value or at the sales price in accordance with authorized procedures for cashless exercises, necessary to satisfy the minimum applicable withholding obligation on exercise, vesting or payment. In no event shall the shares withheld exceed the minimum whole number of shares required for tax withholding under applicable law.

19. Plan Not Funded. Awards payable under the Plan shall be payable in shares or from the general assets of the Company, and no special or separate reserve, fund or deposit shall be made to assure payment of such awards. No Grantee, beneficiary or other person shall have any right, title or interest in any fund or in any specific asset (including shares of Common Stock, except as expressly otherwise provided) of the Company or one of its Subsidiaries by reason of any Award hereunder. Neither the provisions of the Plan (or of any related documents), nor the creation or adoption of the Plan, nor any action taken pursuant to the provisions of the Plan shall create, or be construed to create, a trust of any kind or a fiduciary relationship between the Company or one of its Subsidiaries and any Grantee, beneficiary or other person. To the extent that a Grantee, beneficiary or other person acquires a right to receive payment pursuant to any Award hereunder, such right shall be no greater than the right of any unsecured general creditor of the Company.

20. Privileges of Stock Ownership. Except as otherwise expressly authorized by the Administrator, a Grantee shall not be entitled to any privilege of stock ownership as to any shares of Common Stock not actually delivered to and held of record by the participant. Except as expressly required by Section 11.1 or otherwise expressly provided by the Administrator, no adjustment will be made for dividends or other rights as a shareholder for which a record date is prior to such date of delivery.

21. Governing Law; Severability; Headings. The Plan, the Awards, all documents evidencing awards and all other related documents shall be governed by, and construed in accordance with the laws of the State of Oregon. If a court of competent jurisdiction holds any provision invalid and unenforceable, the remaining provisions of the Plan shall continue in effect. Captions and headings are given to the sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision thereof.

22. No Corporate Action Restriction. The existence of the Plan, the Award Agreements and the Awards granted hereunder shall not limit, affect or restrict in any way the right or power of the Board or the shareholders of the Company to make or authorize: (a) any adjustment, recapitalization, reorganization or other change in the capital structure or business of the Company or any Subsidiary, (b) any merger, amalgamation, consolidation or change in the ownership of the Company or any Subsidiary, (c) any issue of bonds, debentures, capital, preferred or prior preference stock ahead of or affecting the capital stock (or the rights thereof) of the Company or any Subsidiary, (d) any dissolution or liquidation of the Company or any Subsidiary, (e) any sale or transfer of all or any part of the assets or business of the Company or any Subsidiary, or (f) any other corporate act or proceeding by the Company or any Subsidiary. No participant, beneficiary or any other person shall have any claim under any award or award agreement against any member of the Board or the Administrator, or the Company or any employees, officers or agents of the Company or any Subsidiary, as a result of any such action.

Exhibit 10.3

23. Stock Retention Requirement for Executive Officers. The Award Agreement providing for an Award under the Plan to a participant who is the principal executive officer, principal financial officer or chief operating officer, if any, of the Company shall provide that the participant shall continue to hold the Shares issued in connection with the Award (net of Shares withheld or disposed of to pay applicable income and employment taxes due by the participant) for a period of twelve (12) months following the later of the date of issuance of the Shares to the participant or, in the case of Shares issued as restricted stock, the date of vesting of such Shares. This holding period requirement shall cease to apply (i) following the participant’s termination of employment with the Company, (ii) at such time as the participant has met such share ownership guidelines as may be adopted by the Board and as are applicable to the participant, or (iii) the occurrence of an event described in Section 11.3 (relating to a Merger or Asset Sale) or similar event involving the sale of the Company.

Nature of Business

Pixelworks is a leading provider of high-performance and power-efficient visual processing solutions that bridge the gap between video content formats and rapidly advancing display capabilities. We develop and market semiconductor and software solutions that enable consistently high-quality, authentic viewing experiences in a wide variety of applications from cinema to smartphones. Our primary target markets include Mobile (smartphone, gaming and tablet), Home Entertainment (TV, personal video recorder ("PVR"), over-the-air ("OTA") and projector), Content (creation, remastering and delivery), and Business & Education (projector).

As of December 31, 2021, we had an intellectual property portfolio of 335 patents related to the visual display of digital image data. We focus our research and development efforts on developing video algorithms that improve quality, and architectures that reduce system power, cost, bandwidth and increase overall system performance and device functionality. We seek to expand our technology portfolio through internal development and co-development with business partners, and we continually evaluate acquisition opportunities and other ways to leverage our technology into other high-value markets.

Pixelworks was founded in 1997 and is incorporated under the laws of the state of Oregon. On August 2, 2017, we acquired ViXS Systems, Inc., a corporation organized in Canada ("ViXS") ("the Acquisition").

During the third quarter of 2021, we engaged in a strategic plan to re-align our mobile, projector, and video delivery businesses to improve their focus on the Asia-centered customers and employee stakeholders of those businesses. The global center of the mobile, projector, and video delivery businesses continues to be in Asia, and the steps we have taken to date and going forward are intended to improve our ability to access capital, customers, and talent. We have operated our primary R&D center in Asia for over 15 years and feel that the time is right to take advantage of that existing footprint and develop our subsidiary, Pixelworks Semiconductor Technology (Shanghai) Co., Ltd. (or "PWSH") as a full profit-and-loss center underneath Pixelworks, Inc. for the mobile, projector, and video delivery businesses. Most of these steps have been completed as of the end of 2021.

This plan will further enable PWSH to seek qualification to file an application for an initial public offering on the Shanghai Stock Exchange’s Science and Technology Innovation Board, known as the STAR Market (the “Listing”). We believe that the Listing will have many benefits, including improved access to new capital markets and the funding of its growth worldwide. We presently intend to qualify PWSH to apply for the Listing so that the Listing is consummated in 2023. The process of going public on the STAR Market includes several periods of review and, therefore, is a lengthy process. There is no guarantee that PWSH will be approved for a Listing at any point in the future.

Our consolidated financial statements include the accounts of Pixelworks and its subsidiaries. Intercompany accounts and transactions have been eliminated. All foreign subsidiaries use the U.S. dollar as the functional currency, and as a result, transaction gains and losses are included in the consolidated statements of operations. Transaction (gains) and losses were $(258) and $419 for the years ended December 31, 2021 and 2020, respectively.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") requires us to make estimates and judgments that affect amounts reported in the financial statements and accompanying notes. Our significant estimates and judgments include those related to revenue recognition, valuation of excess and obsolete inventory, lives and recoverability of equipment and other long-lived assets, valuation of goodwill, stock-based compensation and income taxes. The actual results experienced could differ materially from our estimates.

Summary of Significant Accounting Policies

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash and Cash Equivalents

We classify all cash and highly liquid investments with original maturities of three months or less at the date of purchase as cash and cash equivalents. Cash equivalents, which as of December 31, 2021 and 2020 consisted of U.S. denominated money market funds, totaled $15,254 and $23,832 as of December 31, 2021 and 2020, respectively.

Marketable Securities

Our investments in marketable securities are classified as available-for-sale. Available-for-sale securities are stated at fair value based on quoted market prices with unrealized holding gains or losses, net of tax, included in accumulated other comprehensive income, a component of shareholders’ equity. The cost of securities sold is based on the specific identification method.

Accounts Receivable

Accounts receivable are recorded at invoiced amount and do not bear interest when recorded or accrue interest when past due. We maintain an allowance for doubtful accounts for estimated losses that may result from the inability of our customers to make required payments. At the end of each reporting period, we estimate the allowance for doubtful accounts based on an account-by-account risk analysis of outstanding receivable balances. The determination to write-off specific accounts receivable balances is made based on the likelihood of collection and past due status. Past due status is based on invoice date and terms specific to each customer.

Inventories

Inventories consist of finished goods and work-in-process, and are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market (net realizable value).

Property and Equipment

Property and equipment are stated at cost. Depreciation and amortization is calculated on a straight-line basis over the estimated useful life of the assets which are generally as follows:

Software	Lesser of 3 years or contractual license term
Equipment, furniture and fixtures	2 years
Tooling	2 to 4 years
Leasehold improvements	Lesser of lease term or estimated useful life

The cost of property and equipment repairs and maintenance is expensed as incurred.

Licensed Technology

We have capitalized licensed technology assets in other long-term assets. These assets are stated at cost and are amortized on a straight-line basis over the term of the license or the estimated life of the asset, if the license is not contractually limited, which is generally two to five years.

Useful Lives and Recoverability of Equipment and Other Long-Lived Assets

We evaluate the remaining useful life and recoverability of equipment and other assets, including identifiable intangible assets, whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If there is an indicator of impairment, we prepare an estimate of future, undiscounted cash flows expected to result from the use of each asset and its eventual disposition. If these cash flows are less than the carrying value of the asset, we adjust the carrying amount of the asset to its estimated fair value. We have concluded that the carrying value of our long-lived assets is recoverable as of December 31, 2021.

Goodwill

Goodwill is not amortized, rather it is tested, at least annually, for impairment at a reporting unit level. Impairment of goodwill is the condition that exists when the carrying amount of a reporting unit that includes goodwill exceeds its fair value. A goodwill impairment loss is recognized for the amount that the carrying amount of the reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit. If the fair value of a reporting unit exceeds the carrying amount, goodwill of the reporting unit is not considered impaired.

We evaluate impairment using the guidance set forth in FASB Accounting Standards Update No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04") which states that an entity may first assess qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. If determined to be necessary, the quantitative impairment test shall be used to identify goodwill impairment and measure the amount of goodwill impairment loss to be recognized. An entity has an unconditional option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to the quantitative goodwill impairment test. Accordingly, we have elected to bypass the qualitative assessment and proceed directly to the quantitative goodwill impairment test. We tested goodwill for impairment under the quantitative goodwill impairment test during the fourth quarter of 2021 and concluded that goodwill was not impaired.

Warranty Program

We warrant that our products will be free from defects in material and workmanship for a period of twelve months from delivery. Warranty repairs are guaranteed for the remainder of the original warranty period. Our warranty is limited to repairing or replacing products, or refunding the purchase price. At the end of each reporting period, we estimate a reserve for warranty returns based on historical experience and knowledge of any applicable events or transactions. The reserve for warranty returns is included in accrued liabilities in our consolidated balance sheets.

Stock-Based Compensation

We currently sponsor a stock incentive plan that allows for issuance of employee stock options and restricted stock awards, including restricted stock units. We also have an employee stock purchase plan for all eligible employees. The fair value of share-based payment awards is expensed straight-line over the requisite service period, which is generally the vesting period, for the entire award. Additionally, any modification of an award that increases its fair value will require us to recognize additional expense.

The fair value of our stock option grants and purchase rights under our employee stock purchase plan are estimated as of the grant date using the Black-Scholes option pricing model which is affected by our estimates of the risk free interest rate, our expected dividend yield, expected term and the expected share price volatility of our common shares over the expected term. The fair value of our restricted stock awards are based on the market value of our stock on the date of grant.

Research and Development

Costs associated with research and development activities are expensed as incurred, except for items with alternate future uses which are capitalized and depreciated over their estimated useful lives.

On occasion, we enter into co-development arrangements with current or prospective customers to defray a portion of the research and development expenses we expect to incur in connection with our development of an IC product. As amounts become due and payable, they are offset against research and development expense on a pro-rata basis.

Income Taxes

We account for income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between financial statement carrying amounts and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We establish a valuation allowance to reduce deferred tax assets if it is "more likely than not" that a portion or all of the asset will not be realized in future tax returns.

An uncertain tax position represents treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for financial reporting purposes. Until these positions are sustained by the taxing authorities, we do not recognize the tax benefits resulting from such positions and report the tax effects for uncertain tax positions in our consolidated balance sheets.

Risks and Uncertainties

Concentration of Suppliers

We do not own or operate a semiconductor fabrication facility and do not have the resources to manufacture our products internally. We rely on a limited number of foundries and assembly and test vendors to produce all of our wafers and for completion of finished products. We do not have any long-term agreements with any of these suppliers. In light of these dependencies, it is reasonably possible that failure to perform by one of these suppliers could have a severe impact on our results of operations. Additionally, the concentration of these vendors within Taiwan and the People’s Republic of China increases our risk of supply disruption due to natural disasters, economic instability, political unrest or other regional disturbances.

Risk of Technological Change

The markets in which we compete, or seek to compete, are subject to rapid technological change, frequent new product introductions, changing customer requirements for new products and features, and evolving industry standards. The introduction of new technologies and the emergence of new industry standards could render our products less desirable or obsolete, which could harm our business.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist of cash equivalents and accounts receivable. We limit our exposure to credit risk associated with cash equivalent balances by holding our funds in high quality, highly liquid money market accounts. We limit our exposure to credit risk associated with accounts receivable by carefully evaluating creditworthiness before offering terms to customers.

Recent Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2019-12, Simplifying the Accounting for Income Taxes ("ASU 2019-12"). ASU 2019-12 removes certain exceptions to the general principles in Accounting Standards Codification ("ASC") 740 and also clarifies and amends existing guidance to provide for more consistent application. ASU 2019-12 became effective for us in the first quarter of fiscal 2021, and early adoption is permitted. The adoption of ASU 2019-12 did not have a material impact on our financial position, results of operations and cash flows.

In November 2018, the FASB issued Accounting Standards Update No. 2018-18, Collaborative Arrangements: Clarifying the Interaction Between Topic 808 and Topic 606 ("ASU 2018-18"). ASU 2018-18 requires transactions in collaborative arrangements to be accounted for under ASC 606 if the counterparty is a customer for a good or service (or bundle of goods and services) that is a distinct unit of account. The amendment also precludes entities from presenting consideration from transactions with a collaborator that is not a customer together with revenue recognized from contracts with customers. ASU 2018-18 became effective for us on January 1, 2020. The adoption of ASU 2018-18 did not have a material impact on our financial position, results of operations and cash flows.

Short-Term Line of Credit

On December 21, 2010, we entered into a Loan and Security Agreement with Silicon Valley Bank (the "Bank"), which was amended over time, including as recently as December 14, 2020 (as amended, the "Revolving Loan Agreement"). The Revolving Loan Agreement provided a secured working capital-based revolving line of credit (the "Revolving Line") in an aggregate amount of up to the lesser of (i) $10,000, or (ii) $2,500 plus 80% of eligible domestic accounts receivable and certain foreign accounts receivable. The Revolving Line had a maturity date of March 26, 2021. In addition, the Revolving Loan Agreement provided for non-formula advances of up to $10,000 which could be made solely during the last five business days of any fiscal month or quarter and which were required to be repaid by the Company on or before the fifth business day after the applicable fiscal month or quarter end.

The Revolving Loan Agreement, as amended, contained customary affirmative and negative covenants as well as customary events of default. The occurrence of an event of default could have resulted in the acceleration of our obligations under the Revolving Loan Agreement, as amended, and an increase to the applicable interest rate, and would have permitted the Bank to exercise remedies with respect to its security interest. The Revolving Line had a maturity date of March 26, 2021. We did not renew the Revolving Loan Agreement upon its maturity.

As of December 31, 2020, we had no outstanding borrowings on the Revolving Line. 

Paycheck Protection Program Loan

On April 25, 2020, we entered into a loan with Silicon Valley Bank as the lender in an aggregate principal amount of $796 (the “Loan”) pursuant to the Paycheck Protection Program (the “PPP”) under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”).

The Loan was evidenced by a promissory note (the “Note”) dated April 25, 2020, and matured 2 years from the disbursement date. The Note bore interest at a rate of 1.000% per annum, with the first six months of interest deferred. Principal and interest

were payable monthly commencing 6 months after the disbursement date and could be prepaid by the Company at any time prior to maturity with no prepayment penalties. The Note contained customary events of default relating to, among other things, payment defaults or breaches of the terms of the Note. Upon the occurrence of an event of default, the Lender could require immediate repayment of all amounts outstanding under the Note.

Under the terms of the CARES Act, PPP loan recipients can apply for and be granted forgiveness for all or a portion of loans granted under the PPP. The Loan is subject to forgiveness to the extent proceeds are used for payroll costs, including payments required to continue group health care benefits, and certain rent, utility, and mortgage interest expenses (collectively, “Qualifying Expenses”), pursuant to the terms and limitations of the PPP. We used the Loan amount for Qualifying Expenses. During the fourth quarter of 2020, we applied for and received full forgiveness and recorded a gain of $796 within other income in our consolidated statements of operations.

MARKETABLE SECURITIES AND FAIR VALUE MEASUREMENTS

Marketable Securities

We had no marketable securities as of December 31, 2021. As of December 31, 2020, all of our marketable securities were classified as available-for-sale, had contractual maturities of one year or less and consisted of the following:

	Cost		Unrealized Gain (Loss)		Fair Value
Short-term marketable securities:
As of December 31, 2020:
Corporate debt securities	$	253	$	(3)	$	250
	$	253	$	(3)	$	250

Unrealized holding gains and losses are recorded in accumulated other comprehensive income, a component of shareholders’ equity, in the consolidated balance sheets.

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Three levels of inputs may be used to measure fair value:

Level 1:Valuations based on quoted prices in active markets for identical assets and liabilities.

Level 2:Valuations based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3:Valuations based on unobservable inputs in which there is little or no market data available, which require the reporting entity to develop its own assumptions.

The following table presents information about our assets and liabilities measured at fair value on a recurring basis in the consolidated balance sheets as of December 31, 2021 and 2020: 

	Level 1		Level 2		Level 3		Total
As of December 31, 2021:

Cash equivalents:
Money market funds	$	23,832	$	—	$	—	23,832
Short-term marketable securities:
Corporate debt securities	—		250		—		250

We primarily use the market approach to determine the fair value of our financial instruments. The fair value of our current assets and liabilities, including accounts receivable and accounts payable approximates the carrying value due to the short-term nature of these balances. We have currently chosen not to elect the fair value option for any items that are not already required to be measured at fair value in accordance with U.S. GAAP.

Leases [Abstract]

Leases

LEASES

We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities in our consolidated balance sheets.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Operating lease ROU assets also exclude lease incentives received. For purposes of calculating operating lease liabilities, lease terms may be deemed to include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.

We have operating leases for office buildings and one vehicle. Our leases have remaining lease terms of 1 year to 6 years. Supplemental information related to lease expense and valuation of the ROU assets and lease liabilities was as follows:

	Year Ended			Year Ended
	December 31, 2021			December 31, 2020

Revenue from Contract with Customer [Abstract]

Revenue

REVENUE

Revenue is recognized when control of the promised good or service is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our principal revenue generating activities consist of the following:

Product Sales - We sell integrated circuit products, also known as “chips” or “ICs”, based upon a customer purchase order, which includes a fixed price per unit. We have elected to account for shipping and handling as activities to fulfill the promise to transfer the goods, and not evaluate whether these activities are promised services to the customer. We generally satisfy our single performance obligation upon shipment of the goods to the customer and recognize revenue at a point in time upon shipment of the underlying product.

Our shipments are subject to limited return rights subject to our limited warranty for our products sold. In addition, we may provide other credits to certain customers pursuant to price protection and stock rotation rights, all of which are considered variable consideration when estimating the amount of revenue to recognize. We use the “most likely amount” method to determine the amount of consideration to which we are entitled. Our estimate of variable consideration is reassessed at the end of each reporting period based on changes in facts and circumstances. Historically, returns and credits have not been material.

Engineering Services - We enter into contracts for professional engineering services that include software development and customization. We identify each performance obligation in our engineering services agreements (“ESAs”) at contract inception. The ESA generally includes project deliverables specified by the customer. The performance obligations in the ESA are generally combined into one deliverable, with the pricing for services stated at a fixed amount. Services provided under the ESA generally result in the transfer of control over time. We recognize revenue on ESAs based on the proportion of labor hours expended to the total hours expected to complete the contract performance obligation. ESAs could include substantive customer acceptance provisions. In ESAs that include substantive customer acceptance provisions, we recognize revenue upon customer acceptance.

License Revenue - On occasion, we derive revenue from the license of our internally developed intellectual property ("IP"). Additionally, for certain IP license agreements, royalties are collected as customers sell their own products that incorporate our IP. IP licensing agreements that we enter into generally provide licensees the right to incorporate our IP components in their products with terms and conditions that vary by licensee. Fees under these agreements generally include license fees or royalty fees relating to our IP and support service fees, resulting in two performance obligations. We evaluate each performance obligation, which generally results in the transfer of control at a point in time for the license fee and over time for support services. Royalties are recognized as revenue is earned, generally when the customer sells its products that incorporate our IP.

Other - From time-to-time, we enter into arrangements for other revenue generating activities, such as providing technical support services to customers through technical support agreements. In each circumstance, we evaluate such arrangements for our performance obligations which generally results in the transfer of control for such services over time. Historically, such arrangements have not been material to our operating results.

The following table provides information about disaggregated revenue based on the preceding categories for the years ended December 31, 2021 and 2020:

	Year ended December 31,
	2021		2020
IC sales	$	50,807	$	39,205
Engineering services, license and other	4,295		1,650
Total revenues	$	55,102	$	40,855

For segment information, including revenue by geographic region, see "Note 14. Segment Information".

Our contract balances include accounts receivable, deferred revenue and our liability for warranty returns. For information concerning these contract balances, see "Note 3. Balance Sheet Components".

Payment terms and conditions for goods and services provided vary by contract; however, payment is generally required within 30 to 60 days of invoicing.

We have not identified any material costs incurred associated with obtaining a contract with a customer which would meet the criteria to be capitalized, therefore, these costs are expensed as incurred.The aggregate amount of the transaction price allocated to unsatisfied performance obligations with an original expected duration of greater than one year is $30,

RESEARCH AND DEVELOPMENT

During the third quarter of 2021, we entered into a best-efforts co-development agreement with a customer to defray a portion of the research and development expenses we expect to incur in connection with our development of an integrated circuit product. We expect our development costs to exceed the amounts received from the customer, and although we expect to sell units of the product to the customer, there is no commitment or agreement from the customer for such sales at this time. Additionally, we retain ownership of any modifications or improvements to our pre-existing intellectual property and may use such improvements in products sold to other customers.

Under the co-development agreement, $5,800 was payable by the customer within 60 days of the date of the agreement and three additional payments of $2,200, $1,300 and $1,300 are each payable upon completion of certain development milestones. As amounts become due and payable, they are offset against research and development expense on a pro rata basis. During the year ended December 31, 2021, we recognized an offset to research and development expense of $3,962.

Deferred Tax Assets, Liabilities and Valuation Allowance

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts for income tax purposes. Significant components of our deferred tax assets and liabilities are as follows: 

	December 31,
	2021		2020
Deferred tax assets:
Research and experimentation credit and deduction carryforwards	$	62,771	$	65,772
Net operating loss carryforwards	45,985		50,917
Depreciation and amortization	5,664		2,282
Deferred stock-based compensation	994		1,158
Reserves and accrued expenses	992		145
Foreign tax credit carryforwards	208		275

Total gross deferred tax liabilities	(812)		(1,526)
Less valuation allowance	(116,372)		(120,981)
Net deferred tax assets	$	881	$	116

We continue to record a full valuation allowance against our U.S. net deferred tax assets as of December 31, 2021 and 2020, as it is not more likely than not that we will realize a benefit from these assets in a future period. In the third quarter of 2021, we recorded a valuation allowance against our net deferred tax assets in China in conjunction with the restructuring of our intercompany agreements and intellectual property. In the fourth quarter of 2021, we recognized $558 of our Canadian net deferred tax assets as we are more likely than not to realize a benefit from these assets in a future period. We have not provided a valuation allowance against our other foreign net deferred tax assets as we have concluded it is more likely than not that we will realize a benefit from these assets in a future period because our subsidiaries in these jurisdictions are cost-plus taxpayers. The net valuation allowance decreased $4,609 for the year ended December 31, 2021 and decreased $24 for the year ended December 31, 2020.

As of December 31, 2021, we had federal, state and foreign net operating loss carryforwards of $166,448, $6,756 and $39,450 respectively, which will begin to expire in 2022 with $31,705 of our federal net operating loss carryforward lasting indefinitely. As of December 31, 2021, we had available federal, state and foreign research and experimentation tax credit carryforwards of $7,823, $4,993, and $24,252 respectively. The federal and state tax credits will begin expiring in 2022 while the foreign credits have an indefinite life. In addition, our Canadian subsidiary has unclaimed scientific and experimental expenditures to be

carried forward and applied against future income in Canada of approximately $120,906. We have a general foreign tax credit of $118 which will begin to expire in 2022.

Our ability to utilize our federal net operating losses may be limited by Section 382 of the Internal Revenue Code of 1986, as amended, which imposes an annual limit on the ability of a corporation that undergoes an "ownership change" to use its net operating loss carryforwards to reduce its tax liability. An ownership change is generally defined as a greater than 50% increase in equity ownership by 5% shareholders in any three-year period.

We are not indefinitely reinvested in the earnings of our subsidiaries in Canada, Japan and Taiwan and have accrued tax on the future repatriation of cash for jurisdictions where withholding taxes would apply. We are no longer indefinitely reinvested in our China subsidiary and have reversed our previous accrual of $620 as a result of changes to our operating plan and implementation of our China intellectual property strategy.

Uncertain Tax Positions

We have recorded tax liabilities to address potential exposures involving positions that could be challenged by taxing authorities. As of December 31, 2021, the amount of our uncertain tax positions was a liability of $2,493 and a reduction to deferred tax assets of $1,254. As of December 31, 2020, the amount of our uncertain tax positions was a liability of $1,610 and a reduction to deferred tax assets of $1,189.

The following is a summary of the change in our liability for uncertain tax positions and interest and penalties:

During the years ended December 31, 2021 and 2020 we recognized $16 and $18, respectively, of interest and penalties in income tax expense in our consolidated statements of operations.

We file income tax returns in the U.S. and various foreign jurisdictions. A number of years may elapse before an uncertain tax position is resolved by settlement or statute of limitations. Settlement of any particular position could require the use of cash. If the uncertain tax positions we have accrued for are sustained by the taxing authorities in our favor, the reduction of the liability will reduce our effective tax rate. We reasonably expect reductions in the liability for unrecognized tax benefits and interest and penalties of approximately $97 within the next twelve months due to the expiration of statutes of limitation in federal, state and foreign jurisdictions.

We are no longer subject to U.S. federal, state, and foreign examinations for years before 2018, 2017 and 2014, respectively. Our net operating loss and tax credit carryforwards from all years may be subject to adjustment for three years following the year in which utilized. We do not anticipate that any potential tax adjustments will have a significant impact on our financial position or results of operations.

We were not subject to, nor have we received any notice of, income tax examinations in any jurisdiction as of December 31, 2021.

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

Royalties

We license technology from third parties and have agreed to pay certain suppliers a royalty based on the number of chips sold or manufactured, the net sales price of the chips containing the licensed technology or a fixed non-cancelable fee. Royalty expense is recognized based on our estimated average unit cost for royalty contracts with non-cancelable prepayments and the stated contractual per unit rate for all other agreements. Royalty expense was $225 and $242 for the years ended December 31, 2021 and 2020, respectively, which is included in cost of revenue in our consolidated statements of operations.

401(k) Plan

We sponsor a 401(k) plan for eligible employees. Participants may defer a percentage of their annual compensation on a pre-tax basis, not to exceed the dollar limit that is set by law. A discretionary matching contribution by the Company is allowed and is equal to a uniform percentage of the amount of salary reduction elected to be deferred, which percentage will be determined each year by the Company. We made contributions of $55 and $48 to the 401(k) plan during the years ended December 31, 2021 and 2020, respectively.

Software licenses

We acquire rights to use certain software engineer design tools under software licenses.

As of December 31, 2021, future minimum payments under non-cancelable software licenses are as follows: 

Year Ending December 31,	Software licenses
2022	$	1,133
2023	365
	1,498
Less: Interest component	(65)
Present value of minimum software license payments	1,433
Less: Current portion	(1,077)
Long-term portion of obligations	$	356

Other Contractual Obligation

As part of the Acquisition, we acquired debt associated with an agreement with the Government of Canada called Technology Partnerships Canada ("TPC"). As part of the TPC agreement, ViXS Systems Inc. was provided funding to assist in research and development expenses of which a portion was later required to be repaid because the conditions for repayment were met. The scheduled payments are made on a quarterly basis and end in January 2024. $504 and $499 are included in accrued liabilities and current portion of long-term liabilities in our consolidated balance sheet as of December 31, 2021 and 2020, respectively. $57 and $268 are included in long-term liabilities, net of current portion in our consolidated balance sheets as of December 31, 2021 and 2020, respectively.

Contract Manufacturers

In the normal course of business, we commit to purchase products from our contract manufacturers to be delivered within the next 90 days. In certain situations, should we cancel an order, we could be required to pay cancellation fees. Such obligations could impact our immediate results of operations but would not materially affect our business.

Indemnifications

Certain of our agreements include limited indemnification provisions for claims from third-parties relating to our intellectual property. It is not possible for us to predict the maximum potential amount of future payments or indemnification costs under these or similar agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. We have not made any payments under these agreements in the past, and as of December 31, 2021, we have not incurred any material liabilities arising from these indemnification obligations. In the future, however, such obligations could immediately impact our results of operations but are not expected to materially affect our business.

Legal Proceedings

We are subject to legal matters that arise from time to time in the ordinary course of our business. Although we currently believe that resolving such matters, individually or in the aggregate, will not have a material adverse effect on our financial position, our results of operations, or our cash flows, these matters are subject to inherent uncertainties and our view of these matters may change in the future.

Earnings Per Share [Abstract]

Earnings Per Share

EARNINGS PER SHARE

Basic earnings per share amounts are computed based on the weighted average number of common shares outstanding. Diluted weighted average shares outstanding include the weighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period.

The following schedule reconciles the computation of basic and diluted net loss per share (in thousands, except per share data):

	Year Ended December 31,
	2021		2020
Net loss	$	(19,412)	$	(26,529)
Less: Net income attributable to redeemable non-controlling interest	(409)		—
Less: Net income attributable to certain entities owned by employees	(198)		—
Net loss attributable to Pixelworks Inc. - for purposes of earnings per share calculation	$	(20,019)	$	(26,529)
Weighted average shares outstanding - basic and diluted	52,509		40,712
Net loss attributable to Pixelworks, Inc. per share - basic and diluted	$	(0.38)	$	(0.65)

Basic and diluted earnings (loss) per share was computed by dividing the net income (loss) by the weighted-average number of common shares outstanding for the period. The numerator adjustments include an allocation of PWSH income to the redeemable non-controlling interests and the employee owned entities. The equity interest associated with the employee-owned entities are considered participating securities at PWSH and will be allocated income, however, they are not required to fund losses, and therefore, no allocations of losses will be made to the employee owned entities in periods of loss at PWSH. Potentially dilutive common shares from employee equity incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options, the assumed vesting of outstanding restricted stock units, and the assumed issuance of common stock under the employee stock purchase plan.

The following shares were excluded from the calculation of diluted net loss per share as their effect would have been anti-dilutive (in thousands):

	Year Ended December 31,
	2021	2020
Employee equity incentive plans	3,832	4,148

Potentially dilutive common shares from employee equity incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options, the assumed vesting of outstanding restricted stock units, and the assumed issuance of common stock under the employee stock purchase plan.

We pay Cowen a commission equal to three percent (3.0%) of the gross sales proceeds of any common stock sold through Cowen under the Sales Agreement. The Sales Agreement may be terminated by us upon prior notice to Cowen or by Cowen upon prior notice to us, or at any time under certain circumstances, including but not limited to the occurrence of a material adverse change in the Company. We are not obligated to sell any shares under the Sales Agreement.

During the year ended December 31, 2021, we sold an aggregate of 61,018 shares of our common stock under this at the market offering, resulting in aggregate net proceeds to us of approximately $321.

Employee Equity Incentive Plans

On May 23, 2006, our shareholders approved the adoption of the Pixelworks, Inc. 2006 Stock Incentive Plan (the "2006 Plan"). The 2006 Plan has since been amended and restated on certain occasions, most recently on May 10, 2021 when our shareholders approved an increase to the total number of authorized shares to 22,683,333 shares. As of December 31, 2021, 2,105,497 shares were available for grant under the 2006 Plan.

Stock Options

The contractual life of newly issued stock option awards is six years. Our new hire vesting schedule provides that each option becomes exercisable at a rate of 25% on the first anniversary date of the grant and 2.083% on the last day of every month thereafter for a total of 36 additional increments. Our merit vesting schedule provides that merit-type awards become exercisable monthly over a period of three years.

The following is a summary of stock option activity: 

	Number of shares	Weighted average exercise price
Options outstanding as of December 31, 2020:	719,067	$	2.53
Granted	—	—
Exercised	(352,375)	2.47

During the years ended December 31, 2021 and 2020 the total intrinsic value of options exercised was $445 and $28, respectively, for which no income tax benefit has been recorded because a full valuation allowance has been provided for our U.S. deferred tax assets. As of December 31, 2021, options outstanding had a total intrinsic value of $684.

Options outstanding that have vested and are expected to vest as of December 31, 2021 are as follows:

	Number of shares	Weighted average exercise price		Weighted average remaining contractual term	Aggregate intrinsic value
Vested	264,688	$	2.61	3.48	$	491

Restricted Stock

The 2006 Plan provides for the issuance of restricted stock, including restricted stock units. During the years ended December 31, 2021 and 2020 we granted 2,123,844 and 2,137,317 shares, respectively, of restricted stock with a weighted average grant date fair value of $3.70 and $3.42 per share, respectively.

The following is a summary of restricted stock activity:

	Number of shares	Weighted average grant date fair value
Unvested at December 31, 2020:	3,176,605	$	3.68
Granted	2,123,844	3.70
Vested	(1,715,624)	3.67

Unvested at December 31, 2021:	3,316,035	$	3.69
Expected to vest after December 31, 2021	3,090,192	$	3.68

Employee Stock Purchase Plans

On May 18, 2010, our shareholders approved the adoption of the 2010 Pixelworks, Inc. Employee Stock Purchase Plan (the "ESPP") for U.S. employees and for certain foreign subsidiary employees. The ESPP provides for separate offering periods commencing on February 1 and August 1, with the first offering period beginning August 1, 2010. Each offering period continues for a period of 18 months with purchases every six months. Each eligible employee may purchase up to 3,000 shares of stock on each purchase date, with a maximum annual purchase amount of $25. The purchase price is equal to 85% of the lesser of the fair market value of the shares on the offering date or on the purchase date. On May 15, 2020 the ESPP was amended when our shareholders approved an increase to the total number of shares of common stock reserved for issuance to 3,300,000. During the years ended December 31, 2021 and 2020, we issued 159,177 and 202,019 shares, respectively for proceeds of $411 and $529, respectively, under the ESPP.

Stock-Based Compensation Expense

The fair value of stock-based compensation was determined using the Black-Scholes option pricing model and the following weighted average assumptions:

	Year Ended December 31,
	2021		2020
Stock Option Plans:
Risk free interest rate	0	%	2.00	%
Expected dividend yield	0	%	0	%
Expected term (in years)	0		3.75
Volatility	0	%	64	%
Employee Stock Purchase Plan:
Risk free interest rate	0.12	%	0.79	%
Expected dividend yield	0	%	0	%
Expected term (in years)	1.17		1.05
Volatility	75	%	65	%

There were no options granted during the year ended December 31, 2021. The weighted average fair value of options granted during the year ended December 31, 2020 was $0.93. The risk free interest rate is estimated using an average of treasury bill interest rates. The expected dividend yield is zero as we have not paid any dividends to date and do not expect to pay dividends in the future. Expected volatility is estimated based on the historical volatility of our common stock over the expected term as this represents our best estimate of future volatility. The contractual life of newly issued stock options is six years, and we have elected to use the "simplified method" to estimate expected term. Under the simplified method, an option's expected term is calculated as the average of its vesting period and original contractual life. The expected term of ESPP purchase rights is based on the estimated weighted average time to purchase.

As of December 31, 2021, unrecognized stock-based compensation expense is $5,560, which is expected to be recognized as stock-based compensation expense over a weighted average period of 1.12 years.

Redeemable Non-Controlling Interest and Equity Interest of Pwsh Sold to Employees

12 Months Ended

Dec. 31, 2021

Noncontrolling Interest [Abstract]

Redeemable Non-Controlling Interest and Equity Interest of Pwsh Sold to Employees

REDEEMABLE NON-CONTROLLING INTEREST AND EQUITY INTEREST OF PWSH SOLD TO EMPLOYEES

During the third quarter of 2021, Pixelworks, Inc. and our subsidiary, PWSH, entered into a Capital Increase Agreement with certain private equity and strategic investors based in China (collectively, the “Investors”) and certain entities which collectively are owned by approximately 75% of the employees of PWSH and its subsidiaries (collectively, the “ESOP”). The ESOP entities do not qualify as Employee Share Ownership Programs under IRC 4975(e)(7), but function as a qualified ESOP and hold an equity ownership in trust for employees.

The Investors invested approximately $30,844 in exchange for a redeemable non-controlling equity interest of 10.45% of PWSH. The Investors will have a liquidation preference in PWSH, a right to co-sell their interest in PWSH along with the Company on the same terms and conditions as the Company, a right to participate on a pro rata basis in any future financing rounds of PWSH, and the Company’s agreement while it remains an owner of PWSH and for two (2) years thereafter to not compete with the business of PWSH, nor solicit or otherwise cause any of PWSH’s core employees or customers to end their relationship with PWSH. These rights all expire upon initial public offering on the STAR Market. Each Investor has the right to require PWSH to redeem the entire equity interest held by such Investor, at the original purchase price paid plus 3% annual interest, if PWSH does not consummate an initial public offering on the STAR Market on or before June 30, 2024. Based on this contingency, the initial carrying amount of the redeemable non-controlling interests was recorded at fair value on the date of issuance of PWSH equity interests, net of issuance costs and presented in temporary equity on the condensed consolidated balance sheets. The Company has elected to accrete changes in the redemption value of the redeemable non-controlling interests from the issuance date through the earliest redemption date of June 30, 2024 using the interest method. Because the redeemable non-controlling interest is denominated in RMB, it will be revalued to USD at the end of each reporting period, with the changes in carrying value attributable to foreign currency being reflected within accumulated other comprehensive loss on the condensed consolidated balance sheets.

The ESOP entities invested approximately $12,329 in exchange for a redeemable non-controlling equity interest representing 5.95% of PWSH, which includes a discount of 30% from the valuation paid by the Investors. Each of the ESOP entities has the right to require PWSH to redeem the entire equity interest held by such ESOP entities at the original purchase price paid plus 5% annual interest, if PWSH does not achieve its Listing on or before December 31, 2024. Because the ESOP entities are owned by employees of PWSH and its subsidiaries and employees are required to render service until either the initial public offering on the STAR Market or repurchase date, the equity interest owned by the ESOP entities will be accounted for under ASC 718 (Compensation - Stock Compensation). The initial carrying amount of the investment has been recorded as a long-term deposit liability on the condensed consolidated balance sheets as the initial public offering cannot be considered probable at this time. We will recognize the periodic interest component of the award as compensation expense and accrete the long-term deposit liability to its redemption value as of December 31, 2024. Because the long-term deposit liability is denominated in RMB and is considered a monetary liability as defined in ASC 255 (Changing Prices), it will be revalued to USD at the end of each reporting period, with the changes in carrying value recorded as foreign currency gain/loss in our condensed consolidated statements of operations.

The process of going public on the STAR Market includes several periods of review and is therefore a lengthy process. There can be no assurances that PWSH will complete the Listing by June 30, 2024, or at all. In the event Pixelworks, Inc. is required to redeem the entire equity interest held by the Investors or the ESOP entities, we may be required to seek additional capital in order to redeem their PWSH shares and there would be no assurances that such capital would be available on terms acceptable to us, if at all. Any redemptions could have a material adverse effect on our business, financial condition and results of operations. The listing of PWSH on China's STAR Market will not change our status as a U.S. public company.

The components of the change in redeemable non-controlling interests for the year ended December 31, 2021 are presented in the following table (in thousands):

Carrying Value of Redeemable NCI as of January 1, 2021	$	—
Increase in non-controlling interest due to issuance of stock	30,844
Closing costs incurred	(868)
Net income attributable to redeemable non-controlling interest	409

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2021

Accounting Policies [Abstract]

Use of Estimates, Policy

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") requires us to make estimates and judgments that affect amounts reported in the financial statements and accompanying notes. Our significant estimates and judgments include those related to revenue recognition, valuation of excess and obsolete inventory, lives and recoverability of equipment and other long-lived assets, valuation of goodwill, stock-based compensation and income taxes. The actual results experienced could differ materially from our estimates.

Cash and Cash Equivalents, Policy

We classify all cash and highly liquid investments with original maturities of three months or less at the date of purchase as cash and cash equivalents. Cash equivalents, which as of December 31, 2021 and 2020 consisted of U.S. denominated money market funds, totaled $15,254 and $23,832 as of December 31, 2021 and 2020, respectively.

Marketable Securities, Policy

Our investments in marketable securities are classified as available-for-sale. Available-for-sale securities are stated at fair value based on quoted market prices with unrealized holding gains or losses, net of tax, included in accumulated other comprehensive income, a component of shareholders’ equity. The cost of securities sold is based on the specific identification method.

Accounts Receivable, Policy

Accounts receivable are recorded at invoiced amount and do not bear interest when recorded or accrue interest when past due. We maintain an allowance for doubtful accounts for estimated losses that may result from the inability of our customers to make required payments. At the end of each reporting period, we estimate the allowance for doubtful accounts based on an account-by-account risk analysis of outstanding receivable balances. The determination to write-off specific accounts receivable balances is made based on the likelihood of collection and past due status. Past due status is based on invoice date and terms specific to each customer.

Inventories, Policy

Inventories consist of finished goods and work-in-process, and are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market (net realizable value).

Property and Equipment, Policy

Property and equipment are stated at cost. Depreciation and amortization is calculated on a straight-line basis over the estimated useful life of the assets which are generally as follows:

Software	Lesser of 3 years or contractual license term
Equipment, furniture and fixtures	2 years
Tooling	2 to 4 years
Leasehold improvements	Lesser of lease term or estimated useful life

The cost of property and equipment repairs and maintenance is expensed as incurred.

Licensed Technology, Policy

We have capitalized licensed technology assets in other long-term assets. These assets are stated at cost and are amortized on a straight-line basis over the term of the license or the estimated life of the asset, if the license is not contractually limited, which is generally two to five years.

Useful Lives and Recoverability of Equipment and Other Long-Lived Assets, Policy

If there is an indicator of impairment, we prepare an estimate of future, undiscounted cash flows expected to result from the use of each asset and its eventual disposition. If these cash flows are less than the carrying value of the asset, we adjust the carrying amount of the asset to its estimated fair value.

Goodwill, Policy

Goodwill is not amortized, rather it is tested, at least annually, for impairment at a reporting unit level. Impairment of goodwill is the condition that exists when the carrying amount of a reporting unit that includes goodwill exceeds its fair value. A goodwill impairment loss is recognized for the amount that the carrying amount of the reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit. If the fair value of a reporting unit exceeds the carrying amount, goodwill of the reporting unit is not considered impaired.

We evaluate impairment using the guidance set forth in FASB Accounting Standards Update No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04") which states that an entity may first assess qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. If determined to be necessary, the quantitative impairment test shall be used to identify goodwill impairment and measure the amount of goodwill impairment loss to be recognized. An entity has an unconditional option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to the quantitative goodwill impairment test. Accordingly, we have elected to bypass the qualitative assessment and proceed directly to the quantitative goodwill impairment test. We tested goodwill for impairment under the quantitative goodwill impairment test during the fourth quarter of 2021 and concluded that goodwill was not impaired.

Warranty Program, Policy

We warrant that our products will be free from defects in material and workmanship for a period of twelve months from delivery. Warranty repairs are guaranteed for the remainder of the original warranty period. Our warranty is limited to repairing or replacing products, or refunding the purchase price. At the end of each reporting period, we estimate a reserve for warranty returns based on historical experience and knowledge of any applicable events or transactions. The reserve for warranty returns is included in accrued liabilities in our consolidated balance sheets.

Share-Based Compensation, Policy

We currently sponsor a stock incentive plan that allows for issuance of employee stock options and restricted stock awards, including restricted stock units. We also have an employee stock purchase plan for all eligible employees. The fair value of share-based payment awards is expensed straight-line over the requisite service period, which is generally the vesting period, for the entire award. Additionally, any modification of an award that increases its fair value will require us to recognize additional expense.

The fair value of our stock option grants and purchase rights under our employee stock purchase plan are estimated as of the grant date using the Black-Scholes option pricing model which is affected by our estimates of the risk free interest rate, our expected dividend yield, expected term and the expected share price volatility of our common shares over the expected term. The fair value of our restricted stock awards are based on the market value of our stock on the date of grant.

Research and Development, Policy

Costs associated with research and development activities are expensed as incurred, except for items with alternate future uses which are capitalized and depreciated over their estimated useful lives.

On occasion, we enter into co-development arrangements with current or prospective customers to defray a portion of the research and development expenses we expect to incur in connection with our development of an IC product. As amounts become due and payable, they are offset against research and development expense on a pro-rata basis.

Income Taxes, Policy

We account for income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between financial statement carrying amounts and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We establish a valuation allowance to reduce deferred tax assets if it is "more likely than not" that a portion or all of the asset will not be realized in future tax returns.

An uncertain tax position represents treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for financial reporting purposes. Until these positions are sustained by the taxing authorities, we do not recognize the tax benefits resulting from such positions and report the tax effects for uncertain tax positions in our consolidated balance sheets.

Fair Value of Financial Instruments, Policy

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Three levels of inputs may be used to measure fair value:

Level 1:Valuations based on quoted prices in active markets for identical assets and liabilities.

Level 2:Valuations based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3:Valuations based on unobservable inputs in which there is little or no market data available, which require the reporting entity to develop its own assumptions.

Revenue, Policy

Revenue is recognized when control of the promised good or service is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our principal revenue generating activities consist of the following:

Product Sales - We sell integrated circuit products, also known as “chips” or “ICs”, based upon a customer purchase order, which includes a fixed price per unit. We have elected to account for shipping and handling as activities to fulfill the promise to transfer the goods, and not evaluate whether these activities are promised services to the customer. We generally satisfy our single performance obligation upon shipment of the goods to the customer and recognize revenue at a point in time upon shipment of the underlying product.

Our shipments are subject to limited return rights subject to our limited warranty for our products sold. In addition, we may provide other credits to certain customers pursuant to price protection and stock rotation rights, all of which are considered variable consideration when estimating the amount of revenue to recognize. We use the “most likely amount” method to determine the amount of consideration to which we are entitled. Our estimate of variable consideration is reassessed at the end of each reporting period based on changes in facts and circumstances. Historically, returns and credits have not been material.

Engineering Services - We enter into contracts for professional engineering services that include software development and customization. We identify each performance obligation in our engineering services agreements (“ESAs”) at contract inception. The ESA generally includes project deliverables specified by the customer. The performance obligations in the ESA are generally combined into one deliverable, with the pricing for services stated at a fixed amount. Services provided under the ESA generally result in the transfer of control over time. We recognize revenue on ESAs based on the proportion of labor hours expended to the total hours expected to complete the contract performance obligation. ESAs could include substantive customer acceptance provisions. In ESAs that include substantive customer acceptance provisions, we recognize revenue upon customer acceptance.

License Revenue - On occasion, we derive revenue from the license of our internally developed intellectual property ("IP"). Additionally, for certain IP license agreements, royalties are collected as customers sell their own products that incorporate our IP. IP licensing agreements that we enter into generally provide licensees the right to incorporate our IP components in their products with terms and conditions that vary by licensee. Fees under these agreements generally include license fees or royalty fees relating to our IP and support service fees, resulting in two performance obligations. We evaluate each performance obligation, which generally results in the transfer of control at a point in time for the license fee and over time for support services. Royalties are recognized as revenue is earned, generally when the customer sells its products that incorporate our IP.

Other - From time-to-time, we enter into arrangements for other revenue generating activities, such as providing technical support services to customers through technical support agreements. In each circumstance, we evaluate such arrangements for our performance obligations which generally results in the transfer of control for such services over time. Historically, such arrangements have not been material to our operating results.
