A device that captures video includes four primary components: a lens, an image sensor, a video processor and storage memory. The video processoris the most complex of these four primary components as it converts raw video input into a format that can be stored and distributed efficiently and, in somecases, analyzes the video data to automate processes and make intelligent decisions. We combine our processor design capabilities with our expertise invideo and image processing, computer vision algorithms and software development to provide a technology platform that is designed to be easily scalableacross multiple applications in a variety of markets and enable rapid and efficient product development for our customers. Our system-on-a-chip, or SoC,designs fully integrate HD video processing, image processing, computer vision functionality, audio processing, and system functions onto a single chip,delivering exceptional video and image quality at high compression rates, differentiated functionality and low power consumption. The flexibility of our technology platform enables us to deliver our solutions for numerous applications in multiple markets. We initially focused ourtechnology platform on the broadcast infrastructure market, where we were able to differentiate our solutions for broadcast customers based on highperformance, low power consumption, transmission and storage efficiency and small form factor. Leveraging these same capabilities, we then designed high-performance solutions for the camera market. As a result of the advantages of our solutions, we became a leading provider of video processing solutions forcameras that capture both HD video and high-resolution still images simultaneously, such as camcorders, pocket video cameras, wearable cameras and IPsecurity cameras.Over the last several years, we have been expanding our development efforts on computer vision technology that complements our image processingand video compression technology. We believe that enhanced computer vision functionality is critical both to our current video markets, such as IP securitycameras, as well as future markets such as automotive OEM cameras for advanced driving assistance systems, or ADAS, autonomous vehicles, and in thefuture, robotic applications. Our development efforts focused on creating advanced computer vision algorithms and high-performance, low-power hardwareplatforms to enhance processing acceleration, which we refer to as our CVflow architecture. The CVflow architecture supports a variety of computer visionalgorithms, including stereo obstacle detection and terrain mapping technology, and allows customers to differentiate their products by porting their ownalgorithms and neural networks to our CVflow-based chips. In 2017, we introduced our first computer vision semiconductor chip, the CV1 SoC. In 2018, weintroduced three new computer vision based SoCs to enable our customers to develop intelligent camera systems for a variety of markets at different featurelevels.Our revenue over the last three years has been generated primarily from sales of our solutions for incorporation into specialized video and imagecapture devices such as wearable sports cameras, automotive aftermarket cameras, IP security cameras and cameras incorporated into unmanned aerialvehicles, or UAVs or drones. While we will continue to address these markets, we intend to primarily focus our development efforts on computer visionapplications for the professional and consumer IP security camera, including cameras for the connected home, the automotive OEM and robotics markets. Inthe IP security camera market, our computer vision platform enables features such as motion detection, people counting and tracking, package and objectdetection, and facial recognition. In the automotive market, we supply solutions for video recorders, in-cabin and driver monitoring cameras, electronicmirrors, around view monitoring, front camera advanced driving assistance systems, and autonomous driving systems. We have also sought to establishpartnerships with software developers for the automotive market to enable advanced artificial intelligence, or AI, features such as object classification, freespace detection, path planning, and driver monitoring.4 We sell our solutions to leading original design manufacturers, or ODMs, and original equipment manufacturers, or OEMs, globally. In the automotivemarket, we may sell our solutions to Tier 1 suppliers that develop and sell devices incorporating our solutions to automotive OEMs. We refer to ODMs andTier 1 suppliers as our customers and OEMs as our end customers, except as otherwise indicated or as the context otherwise requires.

Information on our website is not incorporated into this AnnualReport on Form 10-K or our other securities filings and is not a part of such filings.Industry BackgroundThe requirements for cameras in the markets we address are consistently evolving. For our key target markets of IP security cameras, automotive andindustrial and robotics applications, these requirements center around computer vision functionality, video definition and frame rates, ability to capture high-quality still images and video, and advanced video features: •Computer Vision. Computer vision represents the field of methods for acquiring, processing, analyzing, and understanding images and high-dimensional data from the real world in order to automate and integrate a wide range of processes. Computer vision is becoming increasinglyimportant for the development of intelligent video camera systems. In the IP security camera market, computer vision can be used for variousfunctions including motion detection to trigger alarms, the counting and tracking of people, and facial recognition. In the automotive market,the application of computer vision for ADAS is increasingly being used to help drivers with functions that include lane detection warning,forward collision warning, blind spot detection, and driver monitoring. Support for stereo video obstacle detection, which utilizes stereocameras to perceive depth, provides an important augmentation to monocular computer vision processing, resulting in an extra margin of safetyfor autonomous driving and other applications, as stereo cameras can detect obstacles without relying on prior training. The application ofcomputer vision may also be used to help control the video encoding process to reduce video bitrates and maximize network efficiency. •Higher Definition and Higher Frame Rates. The demand for enhanced video resolution has been increasing across camera markets. Consumersexpect video quality to be closer to high-resolution still images, which continues to drive the transition from standard definition to Full HDand beyond. Similarly, as new display technologies enable higher resolutions and higher frame rates, we believe consumer demand willcontinue to drive the requirement for ultra high-definition, or UHD or 4K, video capture and transmission.5 •Ability to Capture High-Quality Still Images and Video. Historically, consumers purchased devices that either provide high-quality imagecapture or record high-quality video. This was the result of consumer preference, as reasonably priced and sized devices would provide onlyone of those attributes. However, as a result of technological improvements, consumer devices that deliver both attributes have proliferated tothe point that a pure video capture device or still image capture device is becoming uncommon. Increasingly, devices are able tosimultaneously capture HD video and high-quality still images without adversely impacting the quality of either. We believe devices that cancapture Full HD video while encoding a second mobile resolution video for uploading to the Internet or streaming over a Wi-Fi network willexpand consumer demand for specialized video capture devices. Additionally, we believe advanced low-light processing including highdynamic range and high-ISO processing will continue to improve image quality even in challenging lighting conditions. We believe imagestabilization technology enables stable video recording during high-motion conditions, which are often encountered when using sportscameras and UAVs. •Connectivity. Integrated wireless capability using wireless links such as Bluetooth and Wi-Fi has become a prevalent feature across manyclasses of video capture devices. Consumers want to watch, control and capture real-time video using their smartphones as the remote controland viewer for wirelessly enabled wearable and sports cameras. Additionally, rather than storing images and video to local media andtransferring to a computer later, consumers are demanding the ability to wirelessly transfer and share their video content to websites such asYouTube, Facebook and other online media albums. In video security applications, connectivity to cloud services enable smart homemonitoring in real-time through smartphones or tablets. The storage of video in the cloud also provides protection against theft of the videocontent and enables users the capability to play back the stored video. •Ability to Deliver Feature-Rich Video. The addition of de-warping capability allows cameras to utilize a wide angle or “fish eye” lens to covera wide viewing area. In security applications this capability can allow a single camera to replace multiple cameras and may also eliminate theneed for mechanical pan-tilt-zoom in the cameras. In automotive markets, the ability to combine and display images captured by multiplecameras can allow the automotive camera recorder to capture and display images from the front, rear and sides of the car, which is referred to asaround view monitoring. Wide dynamic range, or WDR, and high dynamic range, or HDR, processing capabilities provide greater dynamicrange between the lightest and darkest areas of an image, permitting captured still images to reveal details that would otherwise be lost againsta bright background.Our Competitive StrengthsOur platform technology solutions provide performance attributes that satisfy the stringent demands of the camera market, enable integration of HDvideo and image capture capabilities in portable devices, provide computer vision capabilities that address the evolving needs of the IP security, automotiveand other markets, and meet the highest standards of the infrastructure market. We believe that our leadership in HD video and image processing applicationsis the result of our competitive strengths, including: •Proprietary Computer Vision Architecture. Our proprietary computer vision processing architecture, known as CVflow, uses a flexiblecomputer vision hardware engine programmed with a high level algorithm description to achieve increased performance while minimizing diesize and power consumption. The CVflow architecture specifies data flow connections between a set of optimized computer vision operators,such as the convolution and matrix multiply functions that are specifically optimized for deep learning algorithms. The CVflow architecturesupports a variety of computer vision algorithms, including stereo obstacle detection and terrain mapping technology, and allows customers todifferentiate their products by porting their own algorithms and neural networks to our CVflow-based chips. •High-Performance, Low Power Video and Image Algorithm Expertise. Our solutions provide Full HD and UHD video at exceptionalresolution and frame rates. Our extensive algorithm expertise, which facilitates efficient video and image compression, enables our solutions toachieve low power consumption without compromising performance. Our solutions achieve high storage and transmission efficiencies throughinnovative and complex video and image compression algorithms that significantly reduce the output bitrate. This smaller storage footprintdirectly benefits the performance of our solutions in several ways including lower memory storage requirements and reduced bandwidth needsfor transmission, which is more conducive to sharing content between devices. These benefits are particularly important in transcoding, thedigital-to-digital conversion of one encoding format to another, and video cloud applications. Our solutions can enable high-performanceimage capture of up to 30 32-megapixel still images per second. Our solutions can deliver clear images in low light conditions because of our3D motion compensated temporal filtering, or MCTF, and multiple exposure processing. Additionally, our WDR and HDR processingcapabilities provide greater dynamic range between the lightest and darkest areas of an image, permitting captured still images to reveal detailsthat would otherwise be lost against a bright background. Our advanced de-warping capability enables cameras to use wide angle lenses tocapture images from a wide area, making it ideal for a variety of IP security camera applications, as well as 3D electronic image stabilizationand surround view for automotive applications.6 •Proprietary Video Processing Architecture. Our proprietary video processing architecture is designed to efficiently integrate our advancedcompression algorithms into our SoCs to offer exceptional storage and transmission efficiencies at lower power across multiple products andend markets. We engineered our very-large-scale integration, or VLSI, architecture with a focus on high-performance video compression asopposed to solutions that are based on a still image processing architecture with add-on video capabilities. Due to our primary focus on videoprocessing compression, we believe that our solutions offer exceptional performance metrics with lower power requirements and reduced diesizes. Our integrated algorithms and architecture also enable simultaneous processing of multiple video and image streams. •Highly Integrated SoC Solutions Based on a Scalable Platform. Our product families leverage our core high-performance video processingarchitecture combined with an extensive set of integrated peripherals, which enables our platform to address the requirements of a variety ofapplications and end markets. Traditional solutions have generally relied upon significant customization to meet the specific requirements ofeach market, resulting in longer design cycles and higher development costs. Our flexible and highly-scalable platform enables us to addressmultiple markets with reduced design cycles and costs. Our platform also enables us to develop fully integrated SoC solutions that provide thesystem functionalities required by our customers on a single chip. Our extensive system integration expertise enables us to integrate core videoprocessing functionality with many peripheral functions such as multiple inputs and outputs, lens controllers, flash controllers and remotecontrol interfaces to reduce system complexity and interoperability issues. Furthermore, we have successfully migrated our process nodes from130nm to 10nm since our founding and have a proven track record of developing and delivering multiple solutions with first-pass siliconsuccess. •Comprehensive and Flexible Software.

The building blocks of our platform are illustrated below:Our technology platform enables the capture of high-resolution still images and HD video while simultaneously encoding HD video for high-qualitystorage and lower resolution video for Internet sharing and wireless networking. Multi stream video capture enhances the consumer experience by offeringthe ability to instantaneously share captured video without having to go through a transcoding process. Our computer stereo vision processing solutionsprovide the ability to detect generic objects without training, allowing more robust decisions to be made in applications such as autonomous driving.AmbaClearOur proprietary image signal processing architecture, known as AmbaClear, incorporates advanced algorithms to convert raw sensor data to high-resolution still and HD video images concurrently. Image processing algorithms include sensor, lens and color correction, demosaicing, which is a processused to reconstruct a full color image from incomplete color samples, noise filtering, detail enhancement and image format conversion. For example, rawsensor data can be captured at up to 16-megapixel resolution at 60 frames per second and filtered down to two megapixels for HD video processing whileselected 16-megapixel frames are concurrently processed by the still image processor. This image processing reduces noise in the input video and improvesvideo quality resulting in better storage and transmission efficiencies. Our WDR and HDR processing capabilities handle greater dynamic range between thelightest and darkest areas of an image, permitting video images to reveal details that would otherwise be lost against a bright background. Our advanced de-warping capability enables cameras to use wide angle lenses to capture images from a wide area, making it ideal for a variety of IP security camera andsurround view applications.10 AmbaCastOur proprietary HD video processing architecture, known as AmbaCast, incorporates advanced algorithms for motion estimation, motion-compensated3D temporal filtering, mode decision and rate control. Successful implementation of these computationally intensive steps has helped us maximizecompression efficiency. We support all three compression profiles—baseline, main and high—as specified in the H.264 video compression standard. We alsosupport the main profile H.265 video compression standard with up to 2x better compression efficiency compared to our H.264 video compressiontechnology.CVflowOur proprietary computer vision processing architecture, known as CVflow, uses a flexible computer vision hardware engine programmed with a highlevel algorithm description to achieve increased performance while minimizing die size and power consumption. This description allows the hardware tomaximize use of its resources by exploiting all available parallelism without software intervention. The CVflow architecture specifies data flow connectionsbetween a set of optimized computer vision operators, such as the convolution and matrix multiply functions that are specifically optimized for deep learningalgorithms. The CVflow architecture supports a variety of computer vision algorithms, including stereo obstacle detection and terrain mappingtechnology. Our platform allows customers to differentiate their products by porting their own algorithms and neural networks to our CVflow-based chipsusing industry-standard training tools and frameworks.Computer Vision TechnologyComputer vision is a core technology that complements our image processing and video compression technology. Our current SoC solutions have upto four high performance ARM processors with NEONTM acceleration that provide a flexible and cost-effective manner in which to run computer visionalgorithms. We are focusing on developing advanced computer vision algorithms and high-performance, low-power hardware acceleration, which is criticalto our current video markets, including IP security, wearable, and UAV cameras, as well as automotive cameras for OEM applications. A significant feature ofour computer vision SoCs is support for stereo obstacle detection, which utilizes stereo cameras to perceive depth. We believe that stereo depth informationprovides an important augmentation to monocular computer vision processing, resulting in an extra margin of safety for autonomous driving and otherapplications. Monocular processing depends on training to detect obstacles, and may not detect obstacles that are not represented in the training set. Stereocameras detect obstacles without relying on training because the depth information is used to directly construct a three-dimensional model of the camera’ssurroundings, including any obstacles. Design MethodologyThe success of our technology platform stems from our algorithm-driven design methodology. We test and verify our algorithms on our proprietaryarchitectural model prior to implementing our algorithms in hardware. Our advanced verification methodology validates our approach through simultaneousmodeling of architecture, algorithms and the hardware itself. This redundant approach enables us to identify and remediate any weaknesses early in thedevelopment cycle, providing a solid foundation on which we build our hardware implementation, and enhances our ability to achieve first-pass siliconsuccess. We have a history of using several process nodes from 130nm through 10nm. In fiscal year 2015, we began investing in development of our nextgeneration SoCs in the 14nm process node and announced our first 14 nm SoC in January 2016. In fiscal year 2017, we began investing in development ofour next generation SoCs in the 10nm process node, and we announced our first 10nm SoC in January 2018. We possess extensive expertise in video andimaging algorithms as well as deep sub-micron digital and mixed-signal design experience.SoC SolutionOur SoC designs integrate HD and UHD video processing, image processing, applications processing and system functions onto a single chip,delivering exceptional video and image quality with differentiated features, including advanced wireless connectivity. Our multi-core DSP architecture ishighly scalable and balances software programmability with hardware-accelerated performance to achieve extremely low power consumption and maximizecamera battery life. The programmable architecture provides our customers with the flexibility they need to quickly develop a wide range of differentiatedproducts. Additionally, our SoCs integrate mixed signal (analog/digital) functionality and high speed interfaces required for interfacing to advanced high-speed CMOS sensors and industry standard interfaces such as USB 3.0 and HDMI 2.0. Our newest SoCs also feature our fully-programmable and highly-efficient CVflow architecture to provide significant computer vision performance with very low power consumption. Recently introduced SoCs include thefollowing:11 •Our 10nm CV22 SoC, which we announced in January 2018, is the second chip in our CVflow family and provides computer visionprocessing required for intelligent home monitoring, automotive, drone, and wearable cameras. The CV22 SoC encodes H.264 AdvancedVideo Coding, or AVC, and H.265 high efficiency video coding, or HEVC, video at rates of up to 4Kp60, with multi-stream support. TheCV22 SoC includes a quad-core 1.2 GHz ARM® Cortex® A53 CPU with NEONTM DSP extensions and floating point unit to providepower for features such as 360 degree de-warping and lens distortion correction, multi-exposure HDR and WDR processing, LED flickermitigation, and multi-sensor support for multi-imager cameras. •Our 10nm CV2 SoC, which we announced in March 2018, is the third chip in our CVflow family and provides computer vision andstereovision processing required for the next generation of intelligent automotive, security, and drone cameras. The CV2 SoC encodesAVC and HEVC video at rates of up to 4Kp90, with multi-stream support. The CV2 SoC includes a quad-core 1.2 GHz ARM® Cortex®A53 CPU with NEONTM DSP extensions and floating point unit to provide power for features such as 360-degree de-warping and lensdistortion correction, multi-exposure HDR and WDR processing, LED flicker mitigation, and multi-sensor support for multi-imagercameras. CV2’s CVflow computer vision processing provides up to 20 times the convolutional neural network, or CNN, processingperformance of CV1. •Our 10nm CV25 SoC, which we announced in January 2019, is the latest chip in our CVflow family and provides computer visionprocessing required for the next generation of affordable and intelligent home monitoring, professional surveillance, and aftermarketautomotive solutions, including smart dash-cameras, driver monitoring systems (DMS), and electronic mirrors. We believe that the CV25SoC will enable cameras to perform advanced artificial intelligence (AI) features like facial recognition in real-time on the camera ratherthan in the cloud. The CV25 SoC encodes AVC and HEVC video at rates of up to 4Kp30, and uses SmartAVCTM and SmartHEVCTMintelligent rate control to achieve low bitrates and minimize cloud storage costs. The CV25 SoC also includes a quad-core 1 GHz ARM®Cortex®-A53 CPU with NEONTM DSP extensions and floating point unit. •Our S6Lm SoC, which we are announcing in April 2019, is designed for a wide range of professional IP and home monitoring cameras andincludes 4K HDR processing and multi-streaming. The S6Lm SoC delivers 5Mp30 + 720p30 + 5Mp1 maximum encoding performance.The S6Lm SoC features a quad-core ARM Cortex A53 CPU for advanced analytics, including object and person detection to reduce falsealarms and maximize battery life in battery-powered designs. The S6Lm uses our next-generation image signal processor to deliver high-quality imaging in low-light conditions, while its HDR processing extracts high image detail in high-contrast scenes.Software Development KitsWe provide to our customers fully-functional software development kits with a suite of application programming interfaces or APIs, which allowcustomers to rapidly integrate our solution, adjust product specifications and provide additional functionality to their systems, thereby enabling them todifferentiate their product offerings and reduce time to market. We have software development kits for all of our core markets. For example, in the securitymarket, we provide a fully-featured IP Camera Software Development Kit, or the IP Camera SDK, based on a LinuxTM operating system. The IP Camera SDKincludes middleware software with multi-streaming capability, control for our 4K H.264/H.265 encoder hardware, support for peripherals such as sensors andWi-Fi chipsets, and other functions needed to build a 4K Ultra HD multi-streaming IP camera. The IP Camera SDK leverages our SoCs’ capabilities for 4Kvideo, multi-streaming, HDR, video de-warping, video analytics, and multi-sensor connectivity. For example, the IP Camera SDK enables an IP camera torecord a stream locally at 4K resolution while streaming another video to a remote client over an Ethernet connection at reduced resolution. We also provideextensions to the IP Camera SDK to address specific submarket segments such as doorbells and battery-powered cameras, which can take advantage of thefast-boot, low power, and advanced multi-view video modes of our chips.We also provide a toolkit to accelerate the development of computer vision algorithms onto our hardware. We provide tools to map algorithms fromcommonly used computer vision frameworks such as Caffe or Tensorflow into our proprietary CVflow architecture. We also provide a framework fordevelopment of higher-level computer vision tasks. This enables our customers to write complex computer vision algorithms with multiple tasks running inparallel, as would be required in applications such as autonomous driving.12 CustomersWe sell our solutions to leading original design manufacturers, or ODMs, and original equipment manufacturers, or OEMs, globally. In the automotivemarket, we may sell our solutions to Tier 1 suppliers that develop and sell devices incorporating our solutions to automotive OEMs. We refer to ODMs andTier 1 suppliers as our customers and OEMs as our end customers, except as otherwise indicated or as the context otherwise requires. In the camera market,our video processing solutions are designed into products from leading OEMs including Axis Communications AB, Avigilon Corporation, DahuaTechnology Co., Ltd., DJI, Denso Ten Limited, Garmin Ltd., GoPro, Hikvision Digital Technology Co., JVC Kenwood Corporation and affiliated entities,Nest Labs (owned by Google LLC, which is owned by Alphabet, Inc.), Pelco by Schneider Electric SE, Ring, Inc. (owned by Amazon, Inc.), Robert BoschGmbH and affiliated entities, Thinkware Corporation, Vivotek, and XiaoYi Technology Co., Ltd., who source our solutions from ODMs including ChiconyElectronics Co., Ltd., Dynacolor, Inc., Flex Ltd., and affiliated entities, affiliated entities of Hon Hai Precision Industry Co., Ltd., Jabil Circuit, Inc., SercommCorporation, and Sky Light Digital Ltd. Sales to customers in Asia accounted for approximately 87%, 79% and 73% of our total revenue in the fiscal years ended January 31, 2019, 2018 and2017, respectively. As many of our OEM end customers or their ODM manufacturers are located in Asia, we anticipate that a majority of our revenue willcontinue to come from sales to customers in that region. Although a large percentage of our sales are made to customers in Asia, we believe that a significantnumber of the products designed by these customers and incorporating our SoCs are then sold to consumers globally. For each fiscal year ended January 31,2019, 2018 and 2017, 98% of our revenue was attributable to sales of our solutions into the camera markets and 2% of our revenue was attributable to sales ofour solutions into the infrastructure market. To date, all of our sales have been denominated in U.S. dollars.We work closely with our end customer OEMs and ODMs throughout their product design cycles that often last six to nine months for the cameramarket, although new products within the camera market may have longer design cycles, particularly those implementing advanced features. As a result, weare able to develop long-term relationships with our customers as our technology becomes embedded in their products. Consequently, we believe we are wellpositioned to not only be designed into our customers’ current products, but also to continually develop next-generation HD video and image processingsolutions for their future products.The product life cycles in the camera market typically range from six to 18 months. We expect that product lifecycles in the automotive OEM and theindustrial and robotics markets will typically be longer than 24 months, as new product introductions occur less frequently. For many of our solutions, earlyengagement with our customers’ technical staff is necessary for success. To ensure an adequate level of early engagement, our application and developmentengineers work closely with our customers to adjust product specifications and add functionality into their products.In fiscal year 2019, the customers representing 10% or more of revenue were Wintech, the Company’s distributor, and Chicony, a direct ODMcustomer, which accounted for approximately 58% and 16% of total revenue, respectively. We currently rely, and expect to continue to rely, on a limitednumber of customers for a significant portion of our revenue.Sales and MarketingWe sell our solutions worldwide using our direct sales force and our distributors. We have direct sales personnel covering the United States, Asia andEurope, and we operate sales offices in Santa Clara, California and Hong Kong, and business development offices in China, Japan, South Korea, and Taiwan.In addition, in each of these locations we employ a staff of field applications engineers to provide direct engineering support locally to our customers.Our sales cycles typically require a significant investment of time and a substantial expenditure of resources before we can realize revenue from thesale of our solutions, if any. Our typical sales cycle consists of a multi-month sales and development process involving our customers’ system designers andmanagement and our sales personnel and software engineers. If successful, this process culminates in a customer’s decision to use our solutions in its system,which we refer to as a design win. Our sales efforts are typically directed to the OEM of the product that will incorporate our video and image processingsolution, but the eventual design and incorporation of our SoC into the product may be handled by an ODM or Tier I supplier on behalf of the OEM. Volumeproduction may begin within six to 18 months after a design win, depending on the complexity of our customer’s product and other factors upon which wemay have little or no influence. Once our solutions have been incorporated into a customer’s design, they are likely to be used for the life cycle of thecustomer’s product. Conversely, a design loss to a competitor will likely preclude any opportunity for future revenue from such customer’s product.13 The end markets into which we sell our products have seen significant changes as consumer preferences have evolved in response to newtechnologies. As a result, the composition of our revenue may differ meaningfully during periods of technology or consumer preference changes. Forexample, in fiscal year 2011, revenue from sales into the pocket video market represented approximately 40% of our total revenue. The proliferation ofsmartphones and their ability to capture high-quality video and still images significantly impacted this market, decreasing pocket video cameras’contribution to approximately zero percent of total revenue by fiscal year 2013. Conversely, our total revenue in the 2013-2018 fiscal years was primarilyderived from markets for specialized video and image capture devices, such as the wearable camera market, the IP security camera market, the automotiveaftermarket and the UAV camera market. While we will continue to address these markets, we intend to primarily focus our development efforts on computervision applications for the professional and consumer IP security, the automotive OEM and industrial and robotics markets. We expect shifts in consumer useof video capture to continue to change over time, as more specialized use cases emerge and video capture continues to proliferate, which could significantlyimpact any of these markets.Our sales are generally made pursuant to purchase orders received approximately four to 18 weeks prior to the scheduled product delivery date,depending upon agreed terms with our customers and the current manufacturing lead time at the time the purchase order is received. These purchase ordersmay be cancelled without charge upon notification within an agreed period of time in advance of the delivery date, which may be as short as 30 days. Due tothe scheduling requirements of our foundry, assembly and test contractors, we generally provide our contractors with our production forecasts and place firmorders for products with our suppliers up to 20 weeks prior to the anticipated delivery date, usually without a purchase order from our own customers. Ourstandard warranty provides that our SoCs containing defects in materials, workmanship or performance may be returned for a refund of the purchase price orfor replacement, at our discretion. We may agree to different warranty terms with specific customers from time to time.ManufacturingWe employ a fabless business model and use third-party foundries and assembly and test contractors to manufacture, assemble and test our solutions.This outsourced manufacturing approach allows us to focus our resources on the design, sales and marketing of our solutions and avoid the cost associatedwith owning and operating our own manufacturing facility. Our engineers work closely with foundries and other contractors to increase yields, lowermanufacturing costs and improve quality. In addition, we believe outsourcing many of our manufacturing and assembly activities provides us the flexibilityneeded to respond to new market opportunities, simplifies our operations and significantly reduces our capital requirements. We do not have a guaranteedlevel of production capacity from any of our suppliers’ facilities to produce our solutions. We carefully qualify each of our suppliers and their subcontractorsand processes in order to meet the extremely high-quality and reliability standards required of our solutions.BacklogOur sales are primarily made through standard purchase orders for delivery of products. Our manufacturing production is based on estimates andadvance non-binding commitments from customers as to future purchases. We follow industry practice that allows customers to cancel, change or defer orderswith limited advance notice prior to shipment. Given this practice, we do not believe that backlog is a reliable indicator of future revenue levels.Wafer FabricationWe have a history of using several process nodes from 130nm through 10nm. We currently manufacture the majority of our solutions in 28nm siliconwafer production process geometry utilizing the services of several different foundries. In fiscal year 2015, we began investing in development in the 14nmprocess node, and we announced our first 14nm SoC in January 2016. In fiscal year 2017, we began investing in development in the 10nm process node, andwe announced our first 10nm SoC in January 2018. Currently, the majority of our SoCs are supplied by Samsung in facilities located in Austin, Texas andSouth Korea, from whom we have the option to purchase both fully-assembled and tested products as well as tested die in wafer form for assembly. We alsohave products supplied by Global UniChip Corporation, or GUC, in Taiwan, from whom we purchase fully-assembled and tested products. The wafers usedby GUC in the assembly of our products are manufactured by Taiwan Semiconductor Manufacturing Co., Ltd., or TSMC, in Taiwan.14 Assembly and TestingSamsung subcontracts the assembly and initial testing of the assembled chips it supplies to us to Signetics Corporation and STATS ChipPAC Ltd. Inthe case of purchases of tested die from Samsung, we contract the assembly to Advanced Semiconductor Engineering, Inc., or ASE. GUC subcontracts theassembly of the products it supplies to us to ASE and Powertech Technology Inc. Final testing of all of our products is handled by King Yuan ElectronicsCo., Ltd. or Sigurd Corporation under the supervision of our engineers. All test software and related processes for our products are developed by ourengineers. We continually monitor the results of testing at all of our test contractors to ensure that our testing procedures are properly implemented.As part of our total quality assurance program, our quality management system has been certified to ISO 9001:2000 standards. Our foundry vendorsare also ISO 9001 certified.Research and DevelopmentWe believe our technology is a competitive advantage and we engage in substantial research and development efforts to develop new products andintegrate additional features and capabilities into our HD and UHD video processing solutions, such as computer vision capabilities. We believe that ourcontinued success depends on our ability to both introduce improved versions of our existing solutions and to develop new solutions for the markets that weserve. As of January 31, 2019, 81% of our employees are engaged in research and development. Our research and development team is comprised of bothsemiconductor and software designers. Our semiconductor design team has extensive experience in large-scale semiconductor design, including architecturedescription, logic and circuit design, implementation and verification. Our software design team has extensive experience in development and verification ofsoftware for the HD video market. Because the integration of hardware and software is a key competitive advantage of our solutions, our hardware andsoftware design teams work closely together throughout the product development process. The experience of our hardware and software design teams enablesus to effectively assess the tradeoffs and advantages when determining which features and capabilities of our solutions should be implemented in hardwareand in software.We have assembled a core team of experienced engineers and systems designers in four research and development design centers located in the UnitedStates, China, Italy, and Taiwan.CompetitionThe global semiconductor market in general, and the video and image processing markets in particular, are highly competitive. We expectcompetition to increase and intensify as more and larger semiconductor companies enter our markets and as we enter new markets, such as the OEMautomotive market. Increased competition could result in price pressure, reduced profitability and loss of market share, any of which could materially andadversely affect our business, revenue and operating results.Our competitors range from large, international companies offering a wide range of semiconductor products to smaller companies specializing innarrow markets. In the IP security camera market, our primary competitors include AMLogic Inc., Fullhan Microelectronics Co., Ltd., Geo Semiconductor,Inc., HiSilicon Technologies Co., Ltd., or HiSilicon, which is owned by Huawei Technologies Co., Ingenic Semiconductor Co., Ltd., Intel Corporation, orIntel, Movidius Ltd., a subsidiary of Intel, Novatek Microelectronics Corp., or Novatek, OmniVision Technologies, Inc., or OmniVision, QualcommIncorporated, or Qualcomm, Realtek Semiconductor Corp., SigmaStar Technology Corp., or SigmaStar, Socionext Inc., or Socionext, an entity created fromthe merger of the system LSI businesses of Fujitsu Ltd. and Panasonic Corporation, or Panasonic, and Texas Instruments Incorporated, or Texas Instruments,as well as vertically integrated divisions of IP Security camera device OEMs, including Axis Communications AB and Sony Corporation, or Sony. In theautomotive camera market, we compete against Allwinner Technology Co., Ltd., Alpha Imaging Technology Corp., Core Logic, Inc., Novatek, NVIDIACorporation, or NVIDIA, NXP Semiconductors N.V., OmniVision, Qualcomm, Renesas Electronics Corporation, SigmaStar, Sunplus Technology Co. Ltd.,Texas Instruments and Xilinx Inc. In the wearable sports camera market, our primary competitors are vertically integrated divisions of camera device OEMs,including Sony, Panasonic, HiSilicon and Socionext. Our primary competitors in the UAV camera market include HiSilicon, Intel, NVIDIA and Qualcomm.Certain of our customers and suppliers also have divisions that produce products competitive with ours.Our ability to compete successfully depends on elements both within and outside of our control, including industry and general economic trends.Many of our competitors are substantially larger, have greater financial, technical, marketing, distribution, customer support and other resources, are moreestablished than we are, and have significantly better brand recognition and broader product offerings which may enable them to develop and enable newtechnology into product solutions better or faster than us and to better withstand adverse economic or market conditions in the future.15 Our ability to compete successfully in the rapidly evolving HD video market depends on several factors, including: •the design and manufacturing of new solutions, including software, that anticipate the video processing and integration needs of ourcustomers’ next-generation products and applications; •performance of our computer vision solutions, as measured by convolutional neural network performance, video and still picture image quality,resolution and frame processing rates; •power consumption efficiency of our solutions; •the ease of implementation of our products by customers; •the strength of customer relationships; •the selection of the foundry process technology and architecture tradeoffs to meet customers’ product requirements in a timely manner; •reputation and reliability; •customer support; and •the cost of the total solution.We believe we compete favorably with respect to these factors, particularly because our solutions typically provide high-performance and low powerconsumption video, CNN performance, efficient integration of our advanced algorithms, exceptional storage and transmission efficiencies at lower power,highly-integrated SoC solutions based on a scalable platform, and comprehensive and flexible software. We cannot ensure, however, that our solutions willcontinue to compete favorably or that we will be successful in the face of increasing competition from new products introduced by existing or newcompetitors.Intellectual PropertyWe rely on a combination of intellectual property rights, including patents, trade secrets, copyrights and trademarks, and contractual protections, toprotect our core technology and intellectual property. As of January 31, 2019, we had 137 issued patents in the United States, 53 of which were continuationpatents, six patents issued in Europe, five issued patents in China, six issued patents in Japan and 76 pending patent applications in the United States. Theissued patents in the United States expire beginning in 2024 through 2035. Many of our issued patents and pending patent applications relate to image andvideo processing and HD video compression.We may not receive competitive advantages from any rights granted under our patents, and our patent applications may not result in the issuance ofany new patents. In addition, any patent we hold may be opposed, contested, circumvented, designed around by a third party or found to be unenforceable orinvalidated. Others may develop technologies that are similar or superior to our proprietary technologies, duplicate our proprietary technologies or designaround patents owned or licensed by us.In addition to our own intellectual property, we also use third-party licenses for certain technologies embedded in our SoC solutions. These aretypically non-exclusive contracts provided under royalty-accruing or paid-up licenses. These licenses are generally perpetual or automatically renewed for solong as we continue to pay any maintenance fees that may be due. To date, maintenance fees have not constituted a significant portion of our capitalexpenditures. While we do not believe our business is dependent to any significant degree on any individual third-party license, we expect to continue to useand may license additional third-party technology for our solutions.We generally control access to and use of our confidential information through employing internal and external controls, including contractualprotections with employees, contractors and customers. We rely in part on U.S. and international copyright laws to protect our mask work. All employees andconsultants are required to execute confidentiality agreements in connection with their employment and consulting relationships with us. We also requirethem to agree to disclose and assign to us all inventions conceived or made in connection with the employment or consulting relationship.Despite our efforts to protect our intellectual property, unauthorized parties may still copy or otherwise obtain and use our software, technology orother information that we regard as proprietary intellectual property. In addition, we continue to operate internationally, and effective patent, copyright,trademark and trade secret protection may not be available or may be limited in foreign countries.16 SeasonalityOur business has tended to be seasonal with higher revenue in our third fiscal quarter as our customers typically increase their production to meetholiday shopping season or year-end demand for their products. Due to recent declines in demand for our solutions in several consumer camera markets, theseasonal impact was not significant in fiscal year 2019. We also may experience seasonally lower demand in our first fiscal quarter in the Asia-based portionof the IP security camera market as a result of industry seasonality and the impact of ODM and OEM factory closures associated with the Chinese New Yearholiday.EmployeesAt January 31, 2019, we employed a total of 750 people, including 165 in the United States, 531 in Asia, primarily in China and Taiwan and 54 inEurope. We also engage temporary employees and consultants. None of our employees are either represented by a labor union or subject to a collectivebargaining agreement. We have not experienced any work stoppages, and we consider our relations with our employees to be good. ITEM 1A. Risk FactorsCertain factors may have a material adverse effect on our business, financial condition and results of operations. You should consider carefully therisks and uncertainties described below, in addition to other information contained in this Annual Report on Form 10-K, including our consolidatedfinancial statements and related notes. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that weare unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business. If any of the followingrisks actually occurs, our business, financial condition, results of operations, and future prospects could be materially and adversely affected. In that event,the trading price of our ordinary shares could decline, and you could lose part or all of your investment.Risks Related to Our Business and Our IndustryIf our customers do not design our solutions into their product offerings, or if our customers’ product offerings are not commercially successful, ourbusiness would suffer.We sell our video and image processing system-on-a-chip, or SoC, solutions to original equipment manufacturers, or OEMs, who include our SoCs intheir products, and to original design manufacturers, or ODMs, who include our SoCs in the products that they supply to OEMs. We refer to ODMs as ourcustomers and OEMs as our end customers, except as otherwise indicated or as the context otherwise requires. Our video and image processing SoCs aregenerally incorporated into our customers’ products at the design stage, which is referred to as a design win. As a result, we rely on OEMs to design oursolutions into the products that they design and sell. Without these design wins, our business would be significantly harmed. We often incur significantexpenditures developing a new SoC solution without any assurance that any OEM will select our solution for design into its own product. Once an OEMdesigns a competitor’s device into its product, it becomes significantly more difficult for us to sell our SoC solutions to that OEM because changing suppliersinvolves significant cost, time, effort and risk for the OEM. Even if an OEM designs one of our SoC solutions into its product, we cannot be assured that the OEM’s product will be commercially successful overtime or at all. For example, in the past we have secured design wins for camera products that were never commercially released by our customer as a result offactors beyond our control. If other products or other product categories incorporating our SoC solutions are not commercially successful or experience rapiddecline, our revenue and business will suffer. For example, we have recently experienced declines in demand for our solutions in several consumer cameramarkets, including wearable cameras, virtual reality cameras and cameras incorporated into unmanned aerial vehicles, also referred to as UAVs or drones,which has negatively impacted our business.Similarly, even if an OEM designs one of our SoC solutions into its product, we are not assured that we will receive or continue to receive new designwins from that OEM. For example, two of our largest OEMs in the consumer camera markets in the past few years, GoPro, Inc., or GoPro, and DajiangInnovation Technology Inc., or DJI, have begun using competing solutions in their mainstream products, which has significantly reduced theseOEMs’demand for our solutions and negatively impacted our revenue.17 If we fail to penetrate new markets, our revenue and financial condition could be harmed.In the past several years, a substantial portion of our revenue was generated from sales of our products to OEMs and ODMs of HD video cameras,including IP security cameras, wearable cameras and UAVs. Our revenue from several of these markets, however, has recently experienced significantdeclines. As a result, we believe that our future revenue growth, if any, will significantly depend on our ability to expand within the camera markets with ourvideo and image processing SoC solutions, particularly in the professional IP security and home security and monitoring camera markets, as well as emergingmarkets such as the OEM automotive and robotics markets. Each of these markets presents distinct and substantial risks and, in many cases, requires us todevelop new functionality or software to address the particular requirements of that market. For example, we expect that computer vision functionality willbecome an increasingly important requirement in many of our current and future markets, including the automotive, IP security camera and roboticsmarkets. As a result, we believe that our ability to develop advanced computer vision technology and gain customer acceptance of our technology is criticalto our future success and our efforts to develop such technology that gains market acceptance may not be successful. Development of products to address newmarkets, such as the OEM automotive and robotics markets, could negatively impact our ability to develop new products for our current markets, which mayharm our financial condition, particularly in the near term. In addition, we anticipate that as we continue to move into new markets, such as the OEMautomotive and robotics markets, we will likely face competition from larger competitors with greater resources and more history in these markets. If any ofthese markets do not develop as we currently anticipate or if we are unable to penetrate them successfully with our solutions, our revenue could decline andour financial condition will be negatively impacted.Some of these markets are primarily served by only a few large, multinational OEMs with substantial negotiating power relative to us and, in someinstances, with internal solutions that are competitive to our products. Meeting the technical requirements and securing design wins with any of thesecompanies will require a substantial investment of our time and resources. We cannot assure that we will secure design wins from these or other companies orthat we will achieve meaningful revenue from the sales of our solutions into these markets. If we fail to penetrate these or other new markets we are targeting,our financial condition would likely suffer.Our target markets may not grow or develop as we currently expect and are subject to market risks, any of which could harm our business, revenueand operating results.In the past few years, a substantial portion of our revenue has been derived from sales of our SoCs to the camera market, and in particular, the IPsecurity camera market, automotive camera market, wearable camera market and UAV market. While we will continue to provide solutions addressing thesemarkets, we are focusing our development resources on addressing computer vision applications, primarily in the professional IP security and home securityand monitoring camera markets, the OEM automotive and robotics markets, with our computer vision solutions. The application of computer visionfunctionality in these markets is relatively new and we may be unable to predict the timing or development of these markets with accuracy. For example, aslower than expected adoption rate for computer vision technology in the IP security camera market could slow the demand for our new solutions. Similarly,a slower than anticipated adoption of electronic mirrors, advanced driving assistance systems and autonomous driving functionality could reduce demand forour new computer vision solutions. If our key target markets, such as automotive cameras, IP security cameras and cameras for robotic applications, do notgrow or develop in ways that we currently expect, demand for our video and image processing SoCs may not materialize as expected and our business andoperating results could suffer.Global economic and political conditions, including possible trade tariffs and restrictions, may have an impact on our business and financialcondition in ways that we currently cannot predict.Recently proposed public policy changes and the imposition of trade tariffs and restrictions between the United States and China have, in our view,created and will continue to create an uncertain business environment. In particular, if additional tariffs or restrictions are imposed on our products or theproducts of our customers, there could be a negative impact on our operations and financial performance. For example, H.R. 5515 - John S. McCain NationalDefense Authorization Act for Fiscal Year 2019, which was recently enacted into law, will negatively impact our two largest China IP security customers andlikely decrease their demand for our solutions. While we anticipate that this new law will likely have a negative impact on our revenue in the near term due touncertainty relating to these customers, we cannot yet predict the longer term impact on our business. In addition, if further restrictions were placed on asignificant customer affecting its ability to do business with us, it would likely have a material adverse effect on our business and financialcondition. Similarly, changes in export classification requirements could impact our ability to supply our solutions to certain companies or in certaincountries. Even in the absence of new restrictions, tariffs or changes in export classifications, it is possible that foreign customers could take actions toreduce dependence on the supply of components, including our solutions, that could be subject to new export classifications, which could have a materialadverse effect on our business and financial condition.18 Our customers may cancel their orders, change production quantities or delay production. If we fail to accurately forecast demand for our solutions,revenue shortfalls or excess, obsolete or insufficient inventory could result.Our customers typically do not provide us with firm, long-term purchase commitments. Substantially all of our sales are made on a purchase orderbasis, which permits our customers to cancel, change or delay their product purchase commitments with little or no notice to us and often without penalty tothem. Because production lead times often exceed the amount of time required by our customers to fill their orders, we often must build SoCs in advance ofreceiving orders from customers, relying on an imperfect demand forecast to project volumes and product mix.Our SoCs are incorporated into products manufactured by or for our end customers, and as a result, demand for our solutions is influenced by thedemand for our customers’ products. Our ability to accurately forecast demand can be adversely affected by a number of factors, including inaccurateforecasting by our customers, miscalculations by our customers of their inventory requirements, changes in market conditions, adverse changes in ourproduct order mix and fluctuating demand for our customers’ products. For example, higher than normal customer inventory levels at GoPro significantlyimpacted our revenue in the first half of fiscal years 2017 and 2018. Higher than normal customer inventory levels can occur in the future. Even after an orderis received, our customers may cancel these orders, request a decrease in production quantities or request a delay in the delivery of our solutions. Any suchcancellation, decrease or delay subjects us to a number of risks, most notably that our projected sales will not materialize on schedule or at all, leading tounanticipated revenue shortfalls and excess or obsolete inventory that we may be unable to sell to other customers.Alternatively, if we are unable to project customer requirements accurately, we may not build enough SoCs, which could lead to delays in productshipments and lost sales opportunities in the near term, as well as force our customers to identify alternative sources, which could affect our ongoingrelationships with these customers. We have in the past had customers significantly increase their requested production quantities with little or no advancenotice. If we do not fulfill customer demands in a timely manner, our customers may cancel their orders and we may be subject to customer claims for cost ofreplacement. In addition, the rapid pace of innovation in our industry could render portions of our inventory obsolete. Excess or obsolete inventory levelscould result in unexpected expenses or increases in our reserves that could adversely affect our business, operating results and financial condition. Inaddition, any significant future cancellations or deferrals of product orders could harm our margins, increase our write-offs due to product obsolescence andrestrict our ability to fund our operations.We depend on a limited number of customers and end customers for a significant portion of our revenue. If we fail to retain or expand our customerrelationships, our revenue could decline.We derive a significant portion of our revenue from a limited number of ODMs who build products on behalf of a limited number of OEMs and from alimited number of OEMs to whom we ship directly. We anticipate that this customer concentration will continue for the foreseeable future. In fiscal year2019, the customers representing 10% or more of revenue were Wintech Microelectronics Co., Ltd., or Wintech, the Company’s distributor, and ChiconyElectronics Co., Ltd., or Chicony, a direct ODM customer, which accounted for approximately 58% and 16% of total revenue, respectively. We believe thatour operating results for the foreseeable future will continue to depend on sales to a relatively small number of customers and end-customers. In the future,these customers may decide not to purchase our SoC solutions at all, may purchase fewer solutions than they did in the past or may alter their purchasingpatterns. As substantially all of our sales to date have been made on a purchase order basis, these customers may cancel, change or delay product purchasecommitments with little or no notice to us and often without penalty and may make our revenue volatile from period to period. In the past, we have hadsignificant customers decrease their demand for our solutions with little advance notice to us. For example, GoPro, our largest OEM customer in fiscal year2017, has recently used a competing solution in its mainstream cameras, which had a significantly negative impact on our revenue. Similarly, our customerDJI recently introduced UAVs incorporating competing solutions that have reduced, and will continue to reduce, DJI’s demand for our solutions. The loss ofa significant customer, or substantial reduction in purchases by a significant customer, could happen again at any time and without notice, and such losswould likely harm our financial condition and results of operations. Moreover, because several of our largest OEM customers have a dominant position intheir markets, a loss of a significant customer may not be easily replaced through sales to other customers in that market.In addition, our relationships with some customers may deter other potential customers who compete with these customers from buying our solutions.To attract new customers or retain existing customers, we may have to offer these customers favorable prices on our solutions. In that event, our averageselling prices and gross margins would decline. The loss of a key customer, a reduction in sales to any key customer or our inability to attract new customerscould seriously impact our revenue and harm our results of operations.19 We do not have long-term supply contracts with our third-party manufacturing vendors, and they may not allocate sufficient capacity to us atreasonable prices to meet future demands for our solutions.The semiconductor industry is subject to intense competitive pricing pressure from customers and competitors. Accordingly, any increase in the costof our solutions, whether by adverse purchase price variances or adverse manufacturing cost variances, will reduce our gross margins and operating profit. Wecurrently do not have long-term supply contracts with most of our primary third-party vendors, and we negotiate pricing with our main vendors on a purchaseorder-by-purchase order basis. Therefore, they are not obligated to perform services or supply product to us for any specific period, in any specific quantities,or at any specific price, except as may be provided in a particular purchase order. Availability of foundry capacity has in the recent past been limited due tostrong demand. The ability of our foundry vendors to provide us with a product, which is sole sourced at each foundry, is limited by their available capacity,existing obligations and technological capabilities. Foundry capacity may not be available when we need it or at reasonable prices. None of our third-partyfoundry or assembly and test vendors has provided contractual assurances to us that adequate capacity will be available to us to meet our anticipated futuredemand for our solutions. Our foundry and assembly and test vendors may allocate capacity to the production of other companies’ products while reducingdeliveries to us on short notice. In particular, other companies that are larger and better financed than we are or that have long-term agreements with ourfoundry or assembly and test vendors may cause our foundry or assembly and test vendors to reallocate capacity to them, decreasing the capacity available tous. Converting or transferring manufacturing from a primary location or supplier to a backup provider could be expensive and would likely take at least twoor more quarters. There are only a few foundries, including Samsung and Taiwan Semiconductor Manufacturing Co., Ltd., or TSMC, that are currentlyavailable for certain advanced process technologies that we utilize or may utilize, such as 10 or 7 nanometer, or nm. Accordingly, as we continue to developsolutions in advanced process nodes we will be increasingly dependent upon such foundries. The unavailability of one or both of these foundries couldsignificantly impact our ability to produce our new products or delay production, which would negatively impact our business.If, in the future, we enter into arrangements with suppliers that include additional fees to expedite delivery, nonrefundable deposits or loans inexchange for capacity commitments or commitments to purchase specified quantities over extended periods, such arrangements may be costly, reduce ourfinancial flexibility and be on terms unfavorable to us, if we are able to secure such arrangements at all. Moreover, if we are able to secure foundry capacity,we may be obligated to use all of that capacity or incur penalties. These penalties could harm our financial results. To date, we have not entered into any sucharrangements with our suppliers. If we need additional foundry or assembly and test subcontractors because of increased demand or the inability to obtaintimely and adequate deliveries from our current vendors, we may not be able to do so cost-effectively, if at all.If we fail to develop and introduce new or enhanced solutions on a timely basis, our ability to attract and retain customers could be impaired andour competitive position could be harmed.We operate in a dynamic environment characterized by rapidly changing technologies and technological obsolescence. To compete successfully, wemust design, develop, market and sell enhanced solutions that provide increasingly higher levels of performance and functionality and that meet the costexpectations of our customers. Our existing or future solutions could be rendered obsolete by the introduction of new products by our competitors;convergence of other markets with or into the camera market; the market adoption of products based on new or alternative technologies; the emergence ofnew industry standards for video compression; or the requirement of additional functionality included in video processors, such as analytics or computervision functionality. In addition, the markets for our solutions are characterized by frequent introduction of next-generation and new products, short productlife cycles, increasing demand for added functionality and significant price competition. If we or our customers are unable to manage product transitions in atimely and cost-effective manner, our business and results of operations would suffer.Our failure to anticipate or timely develop new or enhanced solutions in response to technological shifts could result in decreased revenue and ourcompetitors achieving design wins that we sought. In particular, we may experience difficulties with product design, development of new software,manufacturing, marketing or qualification that could delay or prevent our development, introduction or marketing of new or enhanced solutions. In addition,for some markets, such as the automotive OEM market, we expect that we will need to establish relationships with third-party suppliers or software providersin order to effectively market our solutions to end-customers. Failure to establish these relationships could harm our ability to achieve design wins. Delays inproduct development could impair our relationships with our customers and negatively impact sales of our solutions under development. Moreover, it ispossible that our customers may develop their own product or adopt a competitor’s solution for products that they currently buy from us. If we fail tointroduce new or enhanced solutions that meet the needs of our customers or penetrate new markets in a timely fashion, we will lose market share and ouroperating results will be adversely affected.20 Achieving design wins is subject to lengthy competitive selection processes that require us to incur significant costs. Even if we begin a productdesign, a customer may decide to cancel or change its product plans, resulting in no revenue from such expenditures.We are focused on selling our video and image processing solutions to ODMs and OEMs for incorporation into their products at the design stage.These efforts to achieve design wins typically are lengthy, especially in emerging markets we intend to address such as the OEM automotive market, and inany case can require us to both incur design and development costs and dedicate scarce engineering resources in pursuit of a single customer opportunity. Wemay not prevail in the competitive selection process and, even when we do achieve a design win, we may never generate any revenue despite incurringdevelopment expenditures. For example, in the past we had achieved certain design wins and projected substantial future revenue as a result of such designwins. Subsequently, based on factors outside of our control, the applicable end customers abruptly cancelled the projects, with no notice to us, resulting in aloss of projected revenue. In addition, even if an OEM designs one of our SoC solutions into one of its products, we cannot be assured that we will secure newdesign wins from that OEM for future products. For example, GoPro and DJI have used competing solutions in recently introduced camera products, whichhas had a significant negative impact on our revenue.These risks are exacerbated by the fact that some of our end customers’ products, particularly in the camera market, likely will have short life cycles.Further, even after securing a design win, we have experienced and may again experience delays in generating revenue from our solutions as a result of thelengthy product development cycle typically required, if we generate any revenue at all as a result of any such design win.Our customers generally take a considerable amount of time to evaluate our solutions. The typical time from early engagement by our sales force toactual product introduction runs from nine to 12 months, though it will likely take significantly longer in new markets such as the OEM automotive androbotics markets. The delays inherent in these lengthy sales cycles increase the risk that a customer will decide to cancel, curtail, reduce or delay its productplans, causing us to lose anticipated sales. In addition, any delay or cancellation of a customer’s plans could harm our financial results, as we may haveincurred significant expense and generated no revenue. Finally, our customers’ failure to successfully market and sell their products could reduce demand forour SoC solutions and harm our business, financial condition and results of operations. If we were unable to generate revenue after incurring substantialexpenses to develop any of our solutions, our business would suffer.We expect competition to increase in the future, which could have an adverse effect on our revenue and market share.The global semiconductor market in general, and the video and image processing markets in particular, are highly competitive. We compete indifferent target markets to various degrees on the basis of a number of competitive factors, including our solutions’ performance, features, functionality,energy efficiency, size, ease with which our solution may be integrated into our customers’ products, customer support, reliability and price, as well as on thebasis of our reputation. We expect competition to increase and intensify as more and larger semiconductor companies enter our markets and as existingcompetitors improve or expand their product offerings. We also expect that the trend among large OEMs to seek to develop their own semiconductorsolutions will continue and expand, particularly in camera markets experiencing consolidation, such as the IP security market. In addition, as we move intonew markets, such as the OEM automotive and robotics markets, we will face competition from larger competitors with longer histories in these markets.Increased competition could result in price pressure, reduced profitability and loss of market share, any of which could harm our business, revenue andoperating results.Our competitors range from large, international companies offering a wide range of semiconductor products to smaller companies specializing innarrow markets. In the IP security camera market, our primary competitors include AMLogic Inc., Fullhan Microelectronics Co., Ltd., Geo Semiconductor,Inc., HiSilicon Technologies Co., Ltd., or HiSilicon, which is owned by Huawei Technologies Co., Ingenic Semiconductor Co., Ltd., Intel Corporation, orIntel, Movidius Ltd., a subsidiary of Intel, Novatek Microelectronics Corp., or Novatek, OmniVision Technologies, Inc., or OmniVision, QualcommIncorporated, or Qualcomm, Realtek Semiconductor Corp., SigmaStar Technology Corp., or SigmaStar, Socionext Inc., or Socionext, an entity created fromthe merger of the system LSI businesses of Fujitsu Ltd. and Panasonic Corporation, or Panasonic, and Texas Instruments Incorporated, or Texas Instruments,as well as vertically integrated divisions of IP Security camera device OEMs, including Axis Communications AB and Sony Corporation, or Sony. In theautomotive camera market, we currently compete against Allwinner Technology Co., Ltd., Alpha Imaging Technology Corp., Core Logic, Inc., Novatek, NXPSemiconductors N.V., OmniVision, Qualcomm, Renesas Electronics Corporation, SigmaStar, Sunplus Technology Co. Ltd., Texas Instruments and Xilinx Inc.In the wearable sports camera market, our primary competitors are vertically integrated divisions of camera device OEMs, including Sony, Panasonic,HiSilicon and Socionext. Our primary competitors in the UAV camera market include HiSilicon, Intel, NVIDIA and Qualcomm.Certain of our customers and suppliers also have divisions that produce products competitive with ours and other customers may seek to verticallyintegrate competitive solutions in the future. In addition, certain third-party developers of technology competitive to our solutions have licensed theirtechnology, including image signal processing and computer vision IP, which potentially enables a greater number of competitors to offer competitivesolutions.21 Our ability to compete successfully depends on elements both within and outside of our control, including industry and general economic trends.Many of our competitors are substantially larger, have greater financial, technical, marketing, distribution, customer support and other resources, are moreestablished than we are and have significantly better brand recognition and broader product offerings than us, which may enable them to develop and enablenew technology into product solutions better or faster than us and to better withstand adverse economic or market conditions in the future. Our ability tocompete will depend on a number of factors, including: •our ability to anticipate market and technology trends and successfully develop solutions that meet market needs; •our success in identifying and penetrating new markets, applications and customers; •our ability to understand the price points and performance metrics of competing products in the marketplace; •our solutions’ performance and cost-effectiveness relative to that of competing products; •our ability to gain access to leading design tools and product specifications at the same time as our competitors; •our ability to develop and maintain relationships with key OEMs and ODMs; •our products’ effective implementation of video processing standards; •our ability to protect our intellectual property; •our ability to expand international operations in a timely and cost-efficient manner; •our ability to deliver products in volume on a timely basis at competitive prices; •our ability to support our customers’ incorporation of our solutions into their products; and •our ability to recruit design and application engineers with expertise in image video and image processing technologies and sales andmarketing personnel.Our competitors may also establish cooperative relationships among themselves or with third parties or acquire companies that provide similarproducts to ours. As a result, new competitors or alliances may emerge that could acquire significant market share. Any of these factors, alone or incombination with others, could harm our business and result in a loss of market share and an increase in pricing pressure.Fluctuations in our operating results on a quarterly and annual basis could cause the market price of our ordinary shares to decline.Our revenue and operating results have fluctuated significantly from period to period in the past and are likely to do so in the future. In particular, ourbusiness has tended to be seasonal with higher revenue in our third quarter as our customers typically increase their production to meet holiday shoppingseason or year-end demand for their products. We also may experience seasonally lower demand in our first quarter in the Asia-based portion of the IPsecurity camera market as a result of industry seasonality and the impact of ODM and OEM factory closures associated with the Chinese New Year holiday.As a result, you should not rely on period-to-period comparisons of our operating results as an indication of our future performance. In future periods, ourrevenue and results of operations may be below the expectations of analysts and investors, which could cause the market price of our ordinary shares todecline.Factors that may affect our operating results include: •fluctuations in demand, sales cycles, product mix, and prices for our products; •the forecasting, scheduling, rescheduling or cancellation of orders by our customers; •shifts in consumer or manufacturer preferences and any resultant change in demand for video and image capture devices into which oursolutions are incorporated; •changes in the competitive dynamics of our markets, including new entrants or pricing pressures; •delays in our customers’ ability to manufacture and ship products that incorporate our solutions caused by internal and external factorsbeyond our control; •our ability to successfully define, design and release new solutions in a timely manner that meet our customers’ needs;22 •changes in manufacturing costs, including wafer, test and assembly costs, mask costs, manufacturing yields and product quality andreliability; •timely availability of adequate manufacturing capacity from our manufacturing subcontractors; •the timing of product announcements by our competitors or by us; •incurrence of research and development and related new products expenditures; •write-downs of inventory for excess quantities and technological obsolescence; •future accounting pronouncements and changes in accounting policies; •volatility in our share price, which may lead to higher stock-based compensation expense; •volatility in our effective tax rate; •general socioeconomic and political conditions in the countries where we operate or where our products are sold or used; and •costs associated with litigation, especially related to intellectual property.Moreover, the semiconductor industry has historically been cyclical in nature, reflecting overall economic conditions as well as budgeting andbuying patterns of consumers. We expect these cyclical conditions to continue. As a result, our quarterly operating results are difficult to predict, even in thenear term. Our expense levels are relatively fixed in the short term and are based, in part, on our expectations of future revenue. If revenue levels are below ourexpectations, we may experience material impacts on our business, including declines in margins and profitability, or incur losses. For example, in the firsthalf of fiscal year 2017 and in the fourth quarter of fiscal year 2018, our revenue declined 21% and 19%, respectively, compared to the same periods in theprior fiscal years. For fiscal year 2019, our revenue declined 23% compared to fiscal year 2018 and we incurred our first annual net losses since our initialpublic offering, or IPO, in 2012. The reduced revenues resulted in a substantial decline in cash flows from operating activities. We may experience similardeclines in the future, which would harm our operating results.The average selling prices of video and image processing solutions in our target markets have historically decreased over time and will likely do soin the future, which could harm our revenue and gross margins.Average selling prices of semiconductor products in the markets we serve have historically decreased over time, and we expect such declines tocontinue to occur for our solutions over time. Our gross margins and financial results will suffer if we are unable to offset reductions in our average sellingprices by reducing our costs, developing new or enhanced SoC solutions on a timely basis with higher selling prices or gross margins, or increasing our salesvolumes. Additionally, because we do not operate our own manufacturing, assembly or testing facilities, we may not be able to reduce our costs as rapidly ascompanies that operate their own facilities, and our costs may even increase, which could also reduce our gross margins. In the past, we have reduced theprices of our SoC solutions in anticipation of future competitive pricing pressures, new product introductions by us or our competitors and other factors.Recently, we have experienced competitive pricing pressures at the low ends of the automotive aftermarket camera market and China-based IP securitycamera market. We expect that we will have to address pricing pressures again in the future, particularly in markets experiencing consolidation, which couldrequire us to reduce the prices of our SoC solutions and harm our operating results.We are dependent on sales of a limited number of video and image processing solutions, and a decline in market adoption of these solutions couldharm our business.We currently derive substantially all of our revenue from the sale of our video and image processing SoCs for use in a relatively small number ofcamera markets and we expect to do so for the next several years. As a result, continued market adoption of our SoC solutions in these camera markets iscritical to our future success. If demand for our SoC solutions were to decline, or demand for products incorporating our solutions declines, or does not growas expected, our revenue would decline and our business would be harmed.23 A substantial portion of our revenue is processed through a single distributor and the loss of this distributor may cause disruptions in our shipments,which may adversely affect our operations and financial condition.We sell a significant percentage of our solutions through a single distributor, Wintech Microelectronics Co., Ltd., or Wintech, which serves as our non-exclusive sales representative in Asia, other than Japan. Approximately 58%, 59% and 60% of our revenue was derived from sales through Wintech for thefiscal years ended January 31, 2019, 2018 and 2017, respectively. We anticipate that a significant portion of our revenue will continue to be derived fromsales through Wintech in the foreseeable future. Our current agreement with Wintech is effective until September 2019, unless it is terminated earlier by eitherparty for any or no reason with 60 days written notice or by failure of the breaching party to cure a material breach within 30 days following written notice ofsuch material breach by the non-breaching party. Our agreement with Wintech will automatically renew for additional successive 12-month terms unless atleast 60 days before the end of the then-current term either party provides written notice to the other party that it elects not to renew the agreement.Termination of the relationship with Wintech, either by us or by Wintech, could result in a temporary or permanent loss of revenue. We may not be successfulin finding suitable alternative distributors on satisfactory terms, or at all, and this could adversely affect our ability to effectively sell our solutions in certaingeographical locations or to certain end customers. Furthermore, Wintech, or any successor or other distributors we do business with, may face issuesobtaining credit, which could impair their ability to make timely payments to us.We are subject to risks associated with our distributors' product inventories.We sell many of our products to customers through distributors who maintain their own inventory of our products for sale to ODMs and end customers.We allow limited price adjustments on sales to distributors. Price adjustments may be effected by way of credits for future product or by cash payments to thedistributor, either in arrears or in advance, using estimates based on historical transactions. Upon the adoption of ASC 606 on February 1, 2018, we recognizerevenue on sales to distributors upon shipment and transfer of control (known as “sell-in” revenue recognition) based on the amount of considerationexpected to be received. To the extent that the actual consideration received is materially different from estimated variable consideration recognized, we maybe required to adjust revenue in subsequent periods.If our distributors are unable to sell an adequate amount of their inventory of our products in a given quarter to ODMs and end customers, or if theydecide to decrease their inventories for any reason, such as adverse global economic conditions or a downturn in technology spending, our sales to thesedistributors and our revenues may decline. We also face the risk that our distributors may purchase, or for other reasons accumulate, inventory levels of ourproducts in any particular quarter in excess of future anticipated sales to end customers. If such sales do not occur in the time frame anticipated by thesedistributors for any reason, these distributors may substantially decrease the amount of product they order from us in subsequent periods until their inventorylevels realign with end-customer demand, which would harm our business and could adversely affect our revenues in such subsequent periods. Our reserveestimates associated with products stocked by our distributors are based largely on reports that our distributors provide to us on a weekly or monthly basis.To date, we believe this resale and channel inventory data have been generally accurate. To the extent that these data are inaccurate or not received in atimely manner, we may not be able to make reserve estimates for future periods accurately or at all.Deterioration of the financial conditions of our customers could adversely affect our operating results.Deterioration of the financial condition of our distributors or customers could adversely impact our collection of accounts receivable. We regularlyreview the collectability and creditworthiness of our distributors and customers to determine an appropriate allowance for doubtful receivables. Based on ourreview of our distributors and customers, we currently have only immaterial reserves for uncollectible accounts. If our uncollectible accounts, however, wereto exceed our current or future allowance for doubtful receivables, our operating results would be negatively impacted.The loss of any of our key personnel could seriously harm our business.We believe our future success depends in large part upon the continuing services of the members of our senior management team and variousengineering and other technical personnel. If one or more of our senior executives or other key personnel are unable or unwilling to continue in their presentpositions, we may not be able to replace them easily or at all, our business may be disrupted, and our financial condition and results of operations may bematerially and adversely affected. In addition, if any member of our senior management team or any of our other key personnel joins a competitor or forms acompeting company, we may experience material disruption of our operations and development plans and lose customers, know-how and key professionalsand staff members, and we may incur increased operating expenses as the attention of other senior executives is diverted to recruit replacements for keypersonnel.24 We rely on highly skilled personnel and, if we are unable to hire, retain or motivate key personnel, we may not be able to grow effectively.Our performance largely depends on the talents and efforts of highly skilled individuals. Our future success depends on our continuing ability toidentify, hire, develop, motivate, and retain highly skilled personnel for all areas of our organization. Our industry is characterized by high demand andintense competition for talent. The pool of qualified candidates is limited, particularly in Silicon Valley and parts of Asia for very-large-scale integration, orVLSI, and computer vision engineers, and certain of our competitors and potential competitors with greater resources have directly targeted ouremployees. In addition, our compensation arrangements, such as our equity award programs, may not always be successful in attracting new employees andretaining and motivating our existing employees. Our continued ability to compete effectively, and to grow our business, depends on our ability to attractnew employees and to retain and motivate our existing employees.If we do not generate revenue growth, we may not be able to execute our business plan and our operating results could suffer.You should not rely on our revenue growth, gross margins or operating results for any prior quarterly or annual periods as an indication of our futureoperating performance. In the past, we experienced significant growth in a short period of time. Our revenue increased from $21.5 million in fiscal year 2008to $316.4 million in fiscal year 2016. Recently, however, we have not sustained this growth rate. Our revenue decreased to $310.3 million in fiscal year 2017and to $295.4 million in fiscal year 2018. Our revenue decreased to $227.8 million in fiscal year 2019, resulting in the first annual net losses since our IPO in2012. We continue to invest in the development of new technology and solutions and expect our research and development expenditures to increasecompared to prior periods. Accordingly, if we are unable to generate or maintain adequate revenue growth, our financial results could suffer and our stockprice could decline.If we are unable to manage any future growth, we may not be able to execute our business plan and our operating results could suffer.Our business has grown rapidly in the past. Our future operating results depend to a large extent on our ability to successfully manage any expansionand growth, including the challenges of managing a company with an executive management team in the United States and the majority of its employees inAsia. We are increasing our investment in research and development and other functions to grow our business and address new markets, such as the OEMautomotive and robotics markets. To manage our growth successfully and handle the responsibilities of being a public company, we believe we musteffectively, among other things: •recruit, hire, train and manage additional qualified engineers for our research and development activities, particularly in our offices inAsia and especially for the positions of semiconductor design and systems, applications engineering and computer vision development; •add additional sales and business development personnel; •add additional finance and accounting personnel; •maintain and improve our administrative, financial and operational systems, procedures and controls; and •enhance our information technology support for enterprise resource planning and design engineering by adapting and expanding oursystems and tool capabilities, and properly training new hires as to their use.We are likely to incur the costs associated with these increased investments earlier than some of the anticipated benefits, and the return on theseinvestments, if any, may be lower, may develop more slowly than we expect or may not materialize. In addition, development of products to addressemerging markets, such as the OEM automotive and robotics markets, could negatively impact our ability to develop new products for our current markets,which may harm our financial condition, particularly in the near term.If we are unable to manage growth effectively, we may not be able to take advantage of market opportunities or develop new solutions, and we mayfail to satisfy customer product or support requirements, maintain product quality, execute our business plan or respond to competitive pressures.25 While we intend to continue to invest in research and development, we may be unable to make the substantial investments that are required toremain competitive in our business.The semiconductor industry requires substantial investment in research and development in order to bring to market new and enhanced solutions. Ourresearch and development expense was $128.1 million, $115.5 million and $101.2 million in fiscal years 2019, 2018 and 2017, respectively. We expect toincrease our research and development expenditures as compared to prior periods as part of our strategy of focusing on the development of innovative videoand image processing solutions with increased functionality, such as computer vision capabilities, and as we target new markets, such as the automotiveOEM and robotics markets. We are unable to predict whether we will have sufficient resources to maintain the level of investment in research anddevelopment required to remain competitive. For example, development in the latest process nodes, such as 10nm and 7nm, can cost significantly more thanrequired to develop in larger process nodes, such as 28nm. This added cost could prevent us from being able to maintain a technology advantage over largercompetitors that have significantly more resources to invest in research and development. In addition, we cannot assure you that the technologies which arethe focus of our research and development expenditures will become commercially successful or generate any revenue.We may have difficulty accurately predicting our future revenue and appropriately budgeting our expenses.The rapidly evolving nature of the markets in which we sell our solutions, combined with substantial uncertainty concerning how these markets maydevelop and other factors beyond our control, limits our ability to accurately forecast quarterly or annual revenue. In addition, because we record asignificant portion of our revenue from sales when we have received notification from our distributors that they have sold our products, some of the revenuewe record in a quarter may be derived from sales of products shipped to our distributors during previous quarters. This revenue recognition methodologylimits our ability to forecast quarterly or annual revenue accurately. We continue to expand our staffing and increase our expenditures in anticipation offuture revenue growth. If our revenue does not increase as anticipated, we could incur significant losses due to our higher expense levels if we are not able todecrease our expenses in a timely manner to offset any shortfall in future revenue.We may experience difficulties demonstrating the value to customers of newer, higher priced and higher margin solutions if they believe existingsolutions are adequate to meet end customer expectations.As we develop and introduce new solutions, we face the risk that customers may not value or be willing to bear the cost of incorporating these newersolutions into their products, particularly if they believe their customers are satisfied with current solutions. Regardless of the improved features or superiorperformance of the newer solutions, customers may be unwilling to adopt our new solutions due to design or pricing constraints. Owing to the extensive timeand resources that we invest in developing new solutions, if we are unable to sell customers new generations of our solutions, or if we face pricing pressureson our new solutions, our revenue could decline and our business, financial condition, operating results and cash flows could be negatively affected.The complexity of our solutions could result in unforeseen delays or expenses from undetected defects, errors or bugs in hardware or software whichcould reduce the market adoption of our new solutions, damage our reputation with current or prospective customers and adversely affect our operatingcosts.Highly complex SoC solutions such as ours frequently contain defects, errors and bugs when they are first introduced or as new versions are released.We have in the past and may in the future experience these defects, errors and bugs. If any of our solutions have reliability, quality or compatibility problems,we may not be able to successfully correct these problems in a timely manner or at all. In addition, if any of our proprietary features contain defects, errors orbugs when first introduced or as new versions of our solutions are released, we may be unable to timely correct these problems. Consequently, our reputationmay be damaged and customers may be reluctant to buy our solutions, which could harm our ability to retain existing customers and attract new customers,and could adversely affect our financial results. In addition, these defects, errors or bugs could interrupt or delay sales to our customers. If any of theseproblems are not found until after we have commenced commercial production of a new product, we may incur significant additional development costs andproduct recall, repair or replacement costs. These problems may also result in claims against us by our customers or others.26 Camera manufacturers incorporate components supplied by multiple third parties, and a supply shortage or delay in delivery of these componentscould delay orders for our solutions by our customers.Our customers purchase components used in the manufacture of their cameras from various sources of supply, often involving several specializedcomponents, including lenses, sensors, and memory chips. Any supply shortage or delay in delivery by third-party component suppliers, or a third-partysupplier’s cessation or shut down of its business, may prevent or delay production of our customers’ products. In addition, replacement or substitutecomponents may not be available on commercially reasonable terms, or at all. As a result of delays in delivery or supply shortages of third-party components,orders for our solutions may be delayed or canceled and our business may be harmed. For example, a disruption in the availability of image sensors fromSony Corporation as a result of the April 14, 2016 Kumamoto, Japan earthquake impacted our customers’ ability to build or launch cameras and, as a result,negatively impacted the timing and scope of demand for our SoCs in the second and third quarters of fiscal year 2017. Similarly, our ability to generatedesign wins in some markets, such as the automotive OEM market, requires us to collaborate with third-party software suppliers in order to offer a completesolution to customers. Our inability to successfully collaborate with such third-party suppliers, or such suppliers’ inability to develop and deliver software,could harm our ability to achieve design wins and harm our business. Errors or defects within a camera system or in the manner in which the variouscomponents interact could prevent or delay production of our customers’ products, which could harm our business.We outsource our wafer fabrication, assembly and testing operations to third parties, and if these parties fail to produce and deliver our productsaccording to requested demands in specification, quantity, cost and time, our reputation, customer relationships and operating results could suffer.We rely on third parties for substantially all of our manufacturing operations, including wafer fabrication, assembly and testing. Currently, themajority of our SoCs are supplied by Samsung in facilities located in Austin, Texas and South Korea, from whom we have the option to purchase both fullyassembled and tested products as well as tested die in wafer form for assembly. Samsung subcontracts the assembly and initial testing of the assembled chipsit supplies to us to Signetics Corporation and STATS ChipPAC Ltd. In the case of purchases of tested die from Samsung, we contract the assembly toAdvanced Semiconductor Engineering, Inc., or ASE. We also have products supplied by Global UniChip Corporation, or GUC, in Taiwan, from whom wepurchase fully assembled and tested products. The wafers used by GUC in the assembly of our products are manufactured by TSMC in Taiwan. The assemblyis done by GUC subcontracted assembly suppliers ASE, and Powertech Technology Inc, or PTI. Final testing of all of our products is handled by King YuanElectronics Co., Ltd. or Sigurd Corporation under the supervision of our engineers. We depend on these third parties to supply us with material of a requestedquantity in a timely manner that meets our standards for yield, cost and manufacturing quality. We do not have any long-term supply agreements with any ofour manufacturing suppliers. If one or more of these vendors terminates its relationship with us, or if we encounter any problems with our manufacturingsupply chain, our ability to ship our solutions to our customers on time and in the quantity required would be adversely affected, which in turn could causean unanticipated decline in our sales and damage our customer relationships.If our foundry vendors do not achieve satisfactory yields or quality, our reputation and customer relationships could be harmed.The fabrication of our video and image processing SoC solutions is a complex and technically demanding process. Minor deviations in themanufacturing process can cause substantial decreases in yields, and in some cases, cause production to be suspended. Our foundry vendors, from time totime, experience manufacturing defects and reduced manufacturing yields, including in the fabrication of our SoCs. Changes in manufacturing processes orthe inadvertent use of defective or contaminated materials by our foundry vendors could result in lower than anticipated manufacturing yields orunacceptable performance of our SoCs. Many of these problems are difficult to detect at an early stage of the manufacturing process and may be timeconsuming and expensive to correct. Poor yields from our foundry vendors, or defects, integration issues or other performance problems in our solutions,could cause us significant customer relations and business reputation problems, harm our financial results and give rise to financial or other damages to ourcustomers. Our customers might consequently seek damages from us for their losses. A product liability claim brought against us, even if unsuccessful, wouldlikely be time consuming and costly to defend.Each of our SoC solutions is manufactured at a single location. If we experience manufacturing problems at a particular location, we would be requiredto transfer manufacturing to a new location or supplier. Converting or transferring manufacturing from a primary location or supplier to a backup fabricationfacility could be expensive and could take two or more quarters. During such a transition, we would be required to meet customer demand from our then-existing inventory, as well as any partially finished goods that could be modified to the required product specifications. We do not seek to maintainsufficient inventory to address a lengthy transition period because we believe it is uneconomical to keep more than minimal inventory on hand. As a result,we may not be able to meet customer needs during such a transition, which could delay shipments, cause production delays, result in a decline in our salesand damage our customer relationships.27 We may experience difficulties in transitioning to new wafer fabrication process technologies or in achieving higher levels of design integration,which may result in reduced manufacturing yields, delays in product deliveries and increased costs.We aim to use the most advanced manufacturing process technology appropriate for our products that is available from our third-party foundries. As aresult, we periodically evaluate the benefits of migrating our solutions to smaller geometry process technologies in order to improve performance and reducecosts. We believe this strategy will help us remain competitive. These ongoing efforts require us from time to time to modify the manufacturing processes forour products and to redesign some products, which in turn may result in delays in product deliveries. We may face difficulties, delays and increased expenseas we transition our products to new processes, such as the 7nm process node, and potentially to new foundries. We depend on Samsung and TSMC, as theprincipal foundries for our products, to transition to new processes successfully. We cannot assure you that Samsung or TSMC will be able to effectivelymanage such transitions or that we will be able to maintain our relationship with Samsung or TSMC or develop relationships with new foundries. Moreover,as we utilize more advanced process nodes beyond 10nm, we are increasingly dependent upon Samsung and TSMC, who are the only foundries currentlyavailable for certain advanced process technologies. If we or our foundry vendors experience significant delays in transitioning to smaller geometries or failto efficiently implement transitions, we could experience reduced manufacturing yields, delays in product deliveries and increased costs, all of which couldharm our relationships with our customers and our operating results. As new processes become more prevalent, we expect to continue to integrate greaterlevels of functionality, as well as more end-customer and third-party intellectual property, into our solutions. We may not be able to achieve higher levels ofdesign integration or deliver new integrated solutions on a timely basis.We rely on third-party vendors to supply software development tools to us for the development of our new products, and we may be unable to obtainthe tools necessary to develop or enhance new or existing products.We rely on third-party software development tools to assist us in the design, simulation and verification of new products or product enhancements. Tobring new products or product enhancements to market in a timely manner, or at all, we need software development tools that are sophisticated enough ortechnologically advanced enough to complete our design, simulations and verifications. In the future, the design requirements necessary to meet consumerdemands for more features and greater functionality from our solutions may exceed the capabilities of available software development tools. Unavailabilityof software development tools may result in our missing design cycles or losing design wins, either of which could result in a loss of market share ornegatively impact our operating results.Because of the importance of software development tools to the development and enhancement of our solutions, our relationships with leaders in thecomputer-aided design industry, including Cadence Design Systems, Inc., Mentor Graphics Corporation and Synopsys, Inc., are critical to us. We haveinvested significant resources to develop relationships with these industry leaders. We believe that utilizing next-generation development tools to design,simulate and verify our products will help us remain at the forefront of the video compression market, and develop solutions that utilize leading-edgetechnology on a rapid basis. If these relationships are not successful, we may be unable to develop new products or product enhancements in a timely manner,which could result in a loss of market share, a decrease in revenue or negatively impact our operating results.Our failure to adequately protect our intellectual property rights could impair our ability to compete effectively or defend ourselves from litigation,which could harm our business, financial condition and results of operations.Our success depends, in part, on our ability to protect our intellectual property. We rely primarily on patent, copyright, trademark and trade secretlaws, as well as confidentiality and non-disclosure agreements and other contractual protections, to protect our proprietary technologies and know-how, all ofwhich offer only limited protection. The steps we have taken to protect our intellectual property rights may not be adequate to prevent misappropriation ofour proprietary information or infringement of our intellectual property rights, and our ability to prevent such misappropriation or infringement is uncertain,particularly in countries outside of the United States. The failure of our patents to adequately protect our technology might make it easier for our competitorsto offer similar products or technologies, which would harm our business. For example, our patents and patent applications could be opposed, contested,circumvented, designed around by our competitors or be declared invalid or unenforceable in judicial or administrative proceedings. Our foreign patentprotection is generally not as comprehensive as our U.S. patent protection and may not protect our intellectual property in some countries where our productsare sold or may be sold in the future. Many U.S.-based companies have encountered substantial intellectual property infringement in foreign countries,including countries where we sell products. Even if foreign patents are granted, effective enforcement in foreign countries may not be available. For example,the legal environment relating to intellectual property protection in certain emerging market countries where we operate is relatively weaker, often making itdifficult to create and enforce such rights. We may not be able to effectively protect our intellectual property rights in these emerging markets or elsewhere. Ifsuch an impermissible use of our intellectual property or trade secrets were to occur, our ability to sell our solutions at competitive prices may be adverselyaffected and our business, financial condition, operating results and cash flows could be materially and adversely affected.28 The legal standards relating to the validity, enforceability and scope of protection of intellectual property rights are uncertain and evolving. Wecannot assure you that others will not develop or patent similar or superior technologies, products or services, or that our patents, trademarks and otherintellectual property will not be challenged, invalidated or circumvented by others.Unauthorized copying or other misappropriation of our proprietary technologies could enable third parties to benefit from our technologies withoutpaying us for doing so, which could harm our business. Monitoring unauthorized use of our intellectual property is difficult and costly. Although we are notaware of any unauthorized use of our intellectual property in the past, it is possible that unauthorized use of our intellectual property may have occurred ormay occur without our knowledge. We cannot assure you that the steps we have taken will prevent unauthorized use of our intellectual property. Our failureto effectively protect our intellectual property could reduce the value of our technology in licensing arrangements or in cross-licensing negotiations.We may in the future need to initiate infringement claims or litigation in order to try to protect our intellectual property rights. Litigation, whether weare a plaintiff or a defendant, can be expensive, time-consuming and may divert the efforts of our technical staff and management, which could harm ourbusiness, whether or not such litigation results in a determination favorable to us. Litigation also puts our patents at risk of being invalidated or interpretednarrowly and our patent applications at risk of not being issued. Additionally, any enforcement of our patents or other intellectual property may provokethird parties to assert counterclaims against us. If we are unable to protect our proprietary rights or if third parties independently develop or gain access to ouror similar technologies, our business, revenue, reputation and competitive position could be harmed.Third parties’ assertions of infringement of their intellectual property rights could result in our having to incur significant costs and cause ouroperating results to suffer.The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights and positions, which has resulted inprotracted and expensive litigation for many companies. Certain of our customers have received, and we expect, particularly to the extent we gain greatermarket visibility, that in the future we may receive, communications from others alleging our infringement of their patents, trade secrets or other intellectualproperty rights. In addition, certain of our end customers have been the subject of lawsuits alleging infringement of intellectual property rights by productsincorporating our solutions, including the assertion that the alleged infringement may be attributable, at least in part, to our technology. Lawsuits resultingfrom such allegations could subject us to significant liability for damages and invalidate our proprietary rights, though this has not occurred to date. Anypotential intellectual property litigation also could force us to do one or more of the following: •stop selling products or using technology that contain the allegedly infringing intellectual property; •lose the opportunity to license our technology to others or to collect royalty payments based upon successful protection and assertionof our intellectual property against others; •incur significant legal expenses; •pay substantial damages to the party whose intellectual property rights we may be found to be infringing; •redesign those products that contain the allegedly infringing intellectual property; or •attempt to obtain a license to the relevant intellectual property from third parties, which may not be available on reasonable terms or atall.Any significant impairment of our intellectual property rights from any litigation we face could harm our business and our ability to compete.29 Any potential dispute involving our patents or other intellectual property could affect our customers, which could trigger our indemnificationobligations to them and result in substantial expense to us.In any potential dispute involving our patents or other intellectual property, our customers could also become the target of litigation. Certain of ourcustomers have received notices from third parties claiming to have patent rights in certain technology and inviting our customers to license this technology,and certain of our end customers have been the subject of lawsuits alleging infringement of patents by products incorporating our solutions, including theassertion that the alleged infringement may be attributable, at least in part, to our technology. Because we generally indemnify our customers for intellectualproperty claims made against them for products incorporating our technology, any litigation could trigger technical support and indemnification obligationsunder some of our license agreements, which could result in substantial expense to us. Although we have not incurred significant indemnity expenses relatedto intellectual property claims to date, we anticipate that we will receive requests for indemnity in the future pursuant to our license agreements with ourcustomers. In addition, other customers or end customers with whom we do not have formal agreements requiring us to indemnify them may ask us toindemnify them if a claim is made as a condition to awarding future design wins to us. Because some of our ODMs and OEMs are larger than we are and havegreater resources than we do, they may be more likely to be the target of an infringement claim by third parties than we would be, which could increase ourchances of becoming involved in a future lawsuit. Although we have not yet been subject to such claims, if any such claims were to succeed, we might beforced to pay damages on behalf of our ODMs or OEMs that could increase our expenses, disrupt our ability to sell our solutions and reduce our revenue. Inaddition to the time and expense required for us to supply support or indemnification to our customers, any such litigation could severely disrupt or shutdown the business of our customers, which in turn could hurt our relations with our customers and cause the sale of our products to decrease.We are subject to warranty and product liability claims and to product recalls.From time to time, we are subject to warranty claims that may require us to make significant expenditures to defend these claims or pay damageawards. In the future, we may also be subject to product liability claims resulting from failure of our solutions or if products we design, manufacture, or sell,cause personal injury or property damage, even where the cause is unrelated to product defects. These risks will likely increase as our products are introducedinto new devices, markets, or applications, including autonomous and semi-autonomous automotive, UAV and robotic applications. In the event of awarranty claim, we may also incur costs if we compensate the affected customer. We maintain product liability insurance, but this insurance is limited inamount and subject to significant deductibles. There is no guarantee that our insurance will be available or adequate to protect against all claims. We alsomay incur costs and expenses relating to a recall of one of our customers’ products containing one of our devices. The process of identifying a recalledproduct in consumer devices that have been widely distributed may be lengthy and require significant resources, and we may incur significant replacementcosts, contract damage claims from our customers and reputational harm. Costs or payments made in connection with warranty and product liability claimsand product recalls could harm our financial condition and results of operations, as well as harm our reputation and cause the market value of our ordinaryshares to decline.A breach of our security systems may have a material adverse effect on our business.Our security systems are designed to maintain the physical security of our facilities and information systems and protect our customers’, suppliers’ andemployees’ confidential information. Accidental or willful security breaches or other unauthorized access by third parties to our facilities or our informationsystems or the existence of computer viruses in our data or software could expose us to a risk of information loss and misappropriation of proprietary andconfidential information. Security breaches, computer malware and computer hacking attacks have become more prevalent and sophisticated. Experiencedcomputer programmers and hackers may be able to penetrate our security controls and misappropriate or compromise our confidential information or that ofthird parties or create system disruptions. Computer programmers and hackers also may be able to develop and deploy viruses, worms and other malicioussoftware programs that attack our information systems and cause disruptions of our business. Data security breaches may also result from non-technicalmeans, for example, actions by an employee. Any theft or misuse of this information could result in, among other things, damage to our reputation,allegations by our customers that we have not performed our contractual obligations, litigation by affected parties and possible financial obligations forliabilities and damages related to the theft or misuse of this information, any of which could have a material adverse effect on our business, financialcondition, our reputation, and our relationships with our customers and partners. We also rely on a number of third-party “cloud-based” service providers ofcorporate infrastructure services relating to, among other things, human resources, electronic communication services and some finance functions, and we are,of necessity, dependent on the security systems of these providers. Any security breaches or other unauthorized access by third parties to the systems of ourcloud-based service providers or the existence of computer viruses in their data or software could expose us to a risk of information loss and misappropriationof confidential information. Since the techniques used to obtain unauthorized access or to sabotage systems change frequently and are often not recognizeduntil launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures.30 We rely on third parties to provide services and technology necessary for the operation of our business. Any failure of one or more of our vendors,suppliers or licensors to provide such services or technology could harm our business.We rely on third-party vendors to provide critical services, including, among other things, services related to accounting, human resources,information technology and network monitoring that we cannot or do not create or provide ourselves. We depend on these vendors to ensure that ourcorporate infrastructure will consistently meet our business requirements. The ability of these third-party vendors to successfully provide reliable and high-quality services is subject to technical and operational uncertainties that are beyond our control. While we may be entitled to damages if our vendors fail toperform under their agreements with us, our agreements with these vendors limit the amount of damages we may receive. In addition, we do not know whetherwe will be able to collect on any award of damages or that these damages would be sufficient to cover the actual costs we would incur as a result of anyvendor’s failure to perform under its agreement with us. Upon expiration or termination of any of our agreements with third-party vendors, we may not be ableto replace the services provided to us in a timely manner or on terms and conditions, including service levels and cost, that are favorable to us, and atransition from one vendor to another vendor could subject us to operational delays and inefficiencies until the transition is complete.Additionally, we incorporate third-party technology into some of our products, and we may do so in future products. The operation of our productscould be impaired if errors occur in the third-party technology we use. It may be more difficult for us to correct any errors in a timely manner, if at all, becausethe development and maintenance of the technology is not within our control. We cannot assure you that these third parties will continue to make theirtechnology, or improvements to the technology, available to us, or that they will continue to support and maintain their technology. Further, due to thelimited number of vendors of some types of technology, it may be difficult to obtain new licenses or replace existing technology. Any impairment of thetechnology of or our relationship with these third parties could harm our business.We are subject to governmental laws, regulations and other legal obligations related to privacy and data protection.The legislative and regulatory framework for privacy and data protection issues worldwide is rapidly evolving and is likely to remain uncertain for theforeseeable future. We collect personally identifiable information, or PII, and other data as part of our business processes and activities. This data is subject toa variety of U.S. and international laws and regulations, including oversight by various regulatory or other governmental bodies. Many foreign countries andgovernmental bodies, including the European Union and other relevant jurisdictions where we conduct business, have laws and regulations concerning thecollection and use of PII and other data obtained from their residents or by businesses operating within their jurisdictions that are currently more restrictivethan those in the U.S. For example, effective May 2018, the European Union adopted the General Data Protection Regulation that imposed more stringentdata protection requirements and provided for greater penalties for noncompliance. Any inability, or perceived inability, to adequately address privacy anddata protection concerns, even if unfounded, or to comply with applicable laws, regulations, policies, industry standards, contractual obligations or otherlegal obligations, could result in additional cost and liability to us, damage our reputation and adversely affect our business.Failure to comply with the U.S. Foreign Corrupt Practices Act, or FCPA, and similar laws associated with our activities outside of the United Statescould subject us to penalties and other adverse consequences.We face significant risks if we fail to comply with the FCPA and other anti-corruption laws that prohibit improper payments or offers of payment toforeign governments and political parties by us for the purpose of obtaining or retaining business. In many foreign countries, particularly in countries withdeveloping economies, it may be a local custom that businesses operating in such countries engage in business practices that are prohibited by the FCPA orother applicable laws and regulations. Although we implemented an FCPA compliance program, we cannot assure you that all of our employees and agents,as well as those companies to which we outsource certain of our business operations, will not take actions in violation of our policies and applicable law, forwhich we may be ultimately held responsible. Any violation of the FCPA or other applicable anti-corruption laws could result in severe criminal or civilsanctions and, in the case of the FCPA, suspension or debarment from U.S. government contracting, which could have a material and adverse effect on ourreputation, business, financial condition, operating results and cash flows.31 We, our customers and third-party contractors are subject to increasingly complex environmental regulations and compliance with theseregulations may delay or interrupt our operations and adversely affect our business.We face increasing complexity in our procurement, design, and research and development operations as a result of requirements relating to thematerials composition of our products, including the European Union’s, or EU’s, Restriction on the Use of Certain Hazardous Substances in Electrical andElectronic Equipment, or RoHS, directive, which restricts the content of lead and certain other hazardous substances in specified electronic products put onthe market in the EU and similar Chinese legislation relating to marking of electronic products which became effective in March 2007. Failure to complywith these and similar laws and regulations could subject us to fines, penalties, civil or criminal sanctions, contract damage claims, and take-back of non-compliant products, which could harm our business, reputation and operating results. The passage of similar requirements in additional jurisdictions or thetightening of these standards in jurisdictions where our products are already subject to such requirements could cause us to incur significant expenditures tomake our products compliant with new requirements, or could limit the markets into which we may sell our products.Some of our operations, as well as the operations of our contract manufacturers and foundry vendors and other suppliers, are also regulated undervarious other federal, state, local, foreign and international environmental laws and requirements, including those governing, among other matters, themanagement, disposal, handling, use, labeling of, and exposure to hazardous substances, and the discharge of pollutants into the air and water. Liabilityunder environmental laws can be joint and several and without regard to comparative fault. We cannot assure you that violations of these laws will not occurin the future, as a result of human error, accident, equipment failure or other causes. Environmental laws and regulations have increasingly become morestringent over time. We expect that our products and operations will be affected by new environmental requirements on an ongoing basis, which will likelyresult in additional costs, which could adversely affect our business.Our failure to comply with present and future environmental, health and safety laws could cause us to incur substantial costs, result in civil or criminalfines and penalties and decreased revenue, which could adversely affect our operating results. Failure by our foundry vendors or other suppliers to complywith applicable environmental laws and requirements could cause disruptions and delays in our product shipments, which could adversely affect ourrelations with our ODMs and OEMs and adversely affect our business and results of operations.Regulations related to “conflict minerals” may force us to incur additional expenses, may make our supply chain more complex and may result indamage to our reputation with customers.Pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, the Securities and ExchangeCommission, or the SEC, has adopted requirements for companies that use certain minerals and metals, known as conflict minerals, in their products, whetheror not these products are manufactured by third parties. These requirements require companies to perform due diligence, disclose and report whether or notsuch minerals originate from the Democratic Republic of Congo and adjoining countries. These requirements could adversely affect the sourcing, availabilityand pricing of minerals used in the manufacture of semiconductor devices, including our products. While these requirements continue to be subject toadministrative uncertainty, we have incurred, and may continue to incur, costs to comply with the disclosure requirements, including costs related todetermining the source of any of the relevant minerals and metals used in our products. Since our supply chain is complex, we may not be able to sufficientlyverify the origins for these minerals and metals used in our products through the due diligence procedures that we implement, which may harm ourreputation. In such event, we may also face difficulties in satisfying customers who require that all of the components of our products are certified as conflictmineral free.32 Rapidly changing industry standards could make our video and image processing solutions obsolete, which would cause our operating results tosuffer.We design our video and image processing solutions to conform to video compression standards, including MPEG-2, H.264 and H.265, set byindustry standards setting bodies such as ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. Generally, our solutionscomprise only a part of a camera device. All components of these devices must uniformly comply with industry standards in order to operate efficientlytogether. We depend on companies that provide other components of the devices to support prevailing industry standards. Many of these companies aresignificantly larger and more influential in driving industry standards than we are. Some industry standards may not be widely adopted or implementeduniformly, and competing standards may emerge that may be preferred by our customers or by consumers. If our customers or the suppliers that provide otherdevice components adopt new or competing industry standards with which our solutions are not compatible, or if the industry groups fail to adopt standardswith which our solutions are compatible, our existing solutions would become less desirable to our customers. As a result, our sales would suffer, and wecould be required to make significant expenditures to develop new SoC solutions. For example, if the new H.265 video compression standard is not broadlyadopted by our customers or potential customers, sales of our H.265 compliant solutions would suffer and we may be required to expend substantial resourcesto comply with an alternative video compression standard. In addition, existing standards may be challenged as infringing upon the intellectual propertyrights of other companies or may be superseded by new innovations or standards.Products for communications applications are based on industry standards that are continually evolving. Our ability to compete in the future willdepend on our ability to identify and ensure compliance with these evolving industry standards, including any new video compression standards. Theemergence of new industry standards could render our solutions incompatible with products developed by other suppliers. As a result, we could be requiredto invest significant time and effort and to incur significant expense to redesign our solutions to ensure compliance with relevant standards. If our solutionsare not in compliance with prevailing industry standards for a significant period of time, we could miss opportunities to achieve crucial design wins, whichcould harm our business.We are subject to the cyclical nature of the semiconductor industry.The semiconductor industry is highly cyclical and is characterized by constant and rapid technological change, rapid product obsolescence, priceerosion, evolving standards, short product life cycles and wide fluctuations in product supply and demand. The industry experienced a significant downturnduring the recent global recession. These downturns have been characterized by diminished product demand, production overcapacity, high inventory levelsand accelerated erosion of average selling prices. Any future downturns could harm our business and operating results. Furthermore, any significant upturn inthe semiconductor industry could result in increased competition for access to third-party foundry and assembly capacity. We are dependent on theavailability of this capacity to manufacture and assemble our SoC solutions. None of our third-party foundry or assembly contractors has provided assurancesthat adequate capacity will be available to us in the future.The use of open source software in our products, processes and technology may expose us to additional risks and compromise our proprietaryintellectual property.Our products, processes and technology sometimes utilize and incorporate software that is subject to an open source license. Open source software istypically freely accessible, usable and modifiable. Certain open source software licenses, such as the GNU General Public License, require a user who intendsto distribute the open source software as a component of the user’s software to disclose publicly part or all of the source code to the user’s software. Inaddition, certain open source software licenses require the user of such software to make any derivative works of the open source code available to others onterms unfavorable to us or at no cost. This can subject previously proprietary software to open source license terms.While we monitor the use of open source software in our products, processes and technology and try to ensure that no open source software is used insuch a way as to require us to disclose the source code to the related product, processes or technology when we do not wish to do so, such use couldinadvertently occur. Additionally, if a third-party software provider has incorporated certain types of open source software into software we license from suchthird-party for our products, processes or technology, we could, under certain circumstances, be required to disclose the source code to our products,processes or technology. This could harm our intellectual property position and our business, results of operations and financial condition.33 Some of our operations and a significant portion of our customers and our subcontractors are located outside of the United States, which subjects usto additional risks, including increased complexity and costs of managing international operations and geopolitical instability.We have research and development design centers and business development offices in China, Japan, Italy, South Korea and Taiwan, and we expect tocontinue to conduct business with companies that are located outside the United States, particularly in Asia. We purchase wafers from foreign foundries, haveour solutions assembled and tested by subcontractors located in Asia, and supply our solutions to customers located outside of the United States. Evencustomers of ours that are based in the United States often use contract manufacturers based in Asia to manufacture their products, and these contractmanufacturers typically purchase products directly from us. As a result of our international focus, we face numerous challenges and risks, including: •increased complexity and costs of managing international operations; •longer and more difficult collection of receivables; •difficulties in enforcing contracts generally; •regional economic instability; •geopolitical instability and military conflicts; •limited protection of our intellectual property and other assets; •compliance with local laws and regulations and unanticipated changes in local laws and regulations, including tax laws andregulations; •trade and foreign exchange restrictions and higher tariffs; •travel restrictions; •timing and availability of import and export licenses and other governmental approvals, permits and licenses, including exportclassification requirements; •foreign currency exchange fluctuations relating to our international operating activities; •restrictions imposed by the U.S. government on our ability to do business with certain companies or in certain countries as a result ofinternational political conflicts; •transportation delays and other consequences of limited local infrastructure, and disruptions, such as large scale outages or interruptionsof service from utilities or telecommunications providers; •difficulties in staffing international operations; •heightened risk of terrorist acts; •local business and cultural factors that differ from standards and practices in the U.S.; •differing employment practices and labor relations; •regional health issues and natural disasters; and •work stoppages.34 Our third-party contractors and their suppliers are concentrated in South Korea, Taiwan and Japan, a region subject to earthquakes and othernatural disasters. Any disruption to the operations of these contractors could cause significant delays in the production or shipment of our products.The majority of our products are manufactured by or receive components from third-party contractors located in South Korea, Taiwan and Japan. Therisk of an earthquake or tsunami in South Korea, Taiwan, Japan and elsewhere in the Pacific Rim region is significant due to the proximity of majorearthquake fault lines. For example, in December 2006 a major earthquake occurred in Taiwan and in March 2011 a major earthquake and tsunami occurredin Japan. Although we are not aware of any significant damage suffered by our third-party contractors as a result of those natural disasters, the occurrence ofadditional earthquakes or other natural disasters could result in the disruption of our foundry vendor or assembly and test capacity. A disruption in theavailability of image sensors from Sony Corporation as a result of the April 14, 2016 Kumamoto, Japan earthquake impacted our customers’ ability to buildor launch cameras and, as a result, negatively impacted the timing and scope of demand for our SoCs in fiscal year 2017. Any disruption resulting from suchevents could cause significant delays in the production or shipment of our products until we are able to shift our manufacturing, assembling or testing fromthe affected contractor to another third-party vendor. We may not be able to obtain alternate capacity on favorable terms, or at all.If our operations are interrupted, our business and reputation could suffer.Our operations and those of our manufacturers are vulnerable to interruption caused by technical breakdowns, computer hardware and softwaremalfunctions, software viruses, infrastructure failures, fires, earthquakes, floods, power losses, telecommunications failures, terrorist attacks, wars, Internetfailures and other events beyond our control. Any disruption in our services or operations could result in a reduction in revenue or a claim for substantialdamages against us, regardless of whether we are responsible for that failure. We rely on our computer equipment, database storage facilities and other officeequipment, which are located primarily in the seismically active San Francisco Bay Area and Taiwan. If we suffer a significant database or network facilityoutage, our business could experience disruption until we fully implement our back-up systems.We are subject to regulatory compliance requirements, including Section 404 of the Sarbanes-Oxley Act of 2002, which are costly to comply with,and our failure to comply with these requirements could harm our business and operating results.We are subject to disclosure and compliance requirements associated with being a public company, including but not limited to compliance withSection 404 of the Sarbanes-Oxley Act of 2002. For example, Section 404 of the Sarbanes-Oxley Act requires that our management report on, and ourindependent auditors attest to, the effectiveness of our internal control structure and procedures for financial reporting. Compliance with Section 404 requiresa significant amount of time, expenses and diversion of internal resources. If we or our auditors discover a material weakness in our internal controls, thedisclosure of that fact, even if quickly remedied, could reduce the market’s confidence in our financial statements and harm our stock price. In addition, if wefail to maintain effective controls over financial reporting, we could be subject to sanctions or investigations by The NASDAQ Stock Market, the SEC, orother regulatory authorities. Furthermore, investor perceptions of our company may suffer, and this could cause a decline in the market price of our ordinaryshares. Any inability to provide reliable financial reports or prevent fraud could harm our business. We may not be able to effectively and timely implementnecessary control changes and employee training to ensure continued compliance with the Sarbanes-Oxley Act and other regulatory and reportingrequirements. We cannot assure you that in the future we will be able to continue to fully comply with the requirements of the Sarbanes-Oxley Act or thatmanagement or our auditors will conclude that our internal controls are effective in future periods. Irrespective of compliance with Section 404, any failure ofour internal controls could have a material adverse effect on our stated results of operations and harm our reputation.Changes to financial accounting standards may affect our results of operations and could cause us to change our business practices.We prepare our consolidated financial statements to conform to generally accepted accounting principles, or GAAP, in the United States. Theseaccounting principles are subject to interpretation by the American Institute of Certified Public Accountants, the SEC and various bodies formed to interpretand create accounting rules and regulations. Changes in those accounting rules, including the new revenue recognition guidance and the associated adoptionefforts, which are currently underway, could have a significant effect on our financial results, require significant resources, pose challenges in forecastingrevenue and may affect our reporting of transactions completed before a change is announced. Changes to those rules or the questioning of current practicesmay adversely affect our reported financial results or the way we conduct our business.Upon the adoption of ASC 606 on February 1, 2018, we recognize revenue on sales to distributors upon shipment and transfer of control (known as“sell-in” revenue recognition) based on the amount of consideration expected to be received. To the extent that the actual consideration received ismaterially different from estimated variable consideration recognized, we may be required to adjust revenue in subsequent periods.35 The complexity of calculating our tax provision may result in errors that could result in restatements of our financial statements.We are incorporated in the Cayman Islands and our operations are subject to income and transaction taxes in the United States, China, Hong Kong,Japan, Italy, South Korea, Taiwan and other jurisdictions in which we do business. Due to the complexity associated with the calculation of our tax provision,we have hired independent tax advisors to assist us. If we or our independent tax advisors fail to resolve or fully understand certain issues, there may be errorsthat could result in us having to restate our financial statements. Restatements are generally costly and could adversely impact our results of operations orhave a negative impact on the trading price of our ordinary shares.Changes in effective tax rates or adverse outcomes resulting from examination of our income tax returns could adversely affect our results.Our future effective tax rates could be adversely affected if our earnings are lower than anticipated in countries where we have lower statutory rates andhigher than anticipated in countries where we have higher statutory rates, by changes in the valuation of our deferred tax assets and liabilities, tax effects ofshare-based compensation, or by changes in tax laws, regulations, accounting principles or interpretations thereof. For example, changes in tax laws,including the U.S. federal tax legislation commonly referred to as the Tax Cuts and Jobs Act of 2017 (Tax Act), as well as other factors, could cause us toexperience fluctuations in our tax obligations and effective tax rates and otherwise adversely affect our tax positions and/or our tax liabilities.The Tax Act requires complex computations not previously provided in U.S. tax law. The U.S. Department of Treasury has broad authority to issueregulations and interpretative guidance that may significantly impact how we will apply the law and impact our results of operations in the period issued. Assuch, the application of accounting guidance for such items is currently uncertain. Further, compliance with the Tax Act and the accounting for suchprovisions require accumulation of information not previously required or regularly produced. While we have completed our accounting for the effects of theTax Act, additional regulatory guidance may still be issued by the applicable taxing authorities which could materially affect our tax obligations andeffective tax rate.In addition, our income tax returns are subject to continuous examination by the Internal Revenue Service, or IRS, and other tax authorities. Weregularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. Wecannot assure you that the outcomes from these continuous examinations will not have an adverse effect on our operating results and financial condition.Unfavorable tax law changes, an unfavorable governmental review of our tax returns, changes in our geographical earnings mix or imposition ofwithholding taxes on repatriated earnings could adversely affect our effective tax rate and our operating results.Our operations are subject to certain taxes, such as income and transaction taxes, in the Cayman Islands, the United States, China, Hong Kong, Japan,Italy, South Korea, Taiwan and other jurisdictions in which we do business. A change in the tax laws in the jurisdictions in which we do business, includingan increase in tax rates or an adverse change in the treatment of an item of income or expense, possibly with retroactive effect, could result in a materialincrease in the amount of taxes we incur. In particular, past proposals have been made to change certain U.S. tax laws relating to foreign entities with U.S.connections, which may include us. For example, previously proposed legislation has considered treating certain foreign corporations as U.S. domesticcorporations (and therefore taxable on all of their worldwide income) if the management and control of the foreign corporation occurs, directly or indirectly,primarily within the United States. If such legislation were enacted, we could, depending on the precise form, be subject to U.S. taxation notwithstanding ourdomicile outside the United States. In addition, on October 5, 2015 the Organization for Economic Co-operation and Development, or OECD, whichrepresents a coalition of member countries, released its final reports from the BEPS Action Plans. The final reports include recommendations covering anumber of issues, including country-by-country reporting, permanent establishment rules, transfer pricing rules and tax treaties. These changes, which havebeen or are in the process of being adopted by numerous countries, could increase uncertainties and may adversely affect our provision for income taxes.We are subject to periodic audits or other reviews by tax authorities in the jurisdictions in which we conduct our activities. Any such audit,examination or review requires management’s time, diverts internal resources and, in the event of an unfavorable outcome, may result in additional taxliabilities or other adjustments to our historical results.Because we conduct operations in multiple jurisdictions, our effective tax rate is influenced by the amounts of income and expense attributed to eachsuch jurisdiction. If such amounts were to change so as to increase the amounts of our net income subject to taxation in higher-tax jurisdictions, or if we wereto commence operations in jurisdictions assessing relatively higher tax rates, our effective tax rate could be adversely affected. In addition, we may determinethat it is advisable from time to time to repatriate earnings from subsidiaries under circumstances that could give rise to imposition of potentially significantwithholding taxes by the jurisdictions in which such amounts were earned, without our receiving the benefit of any offsetting tax credits, which could alsoadversely impact our effective tax rate.36 We may be classified as a passive foreign investment company which could result in adverse U.S. federal income tax consequences for U.S. holdersof our ordinary shares.Based on the current and anticipated valuation of our assets and the composition of our income and assets, we do not expect to be considered apassive foreign investment company, or PFIC, for U.S. federal income tax purposes for our 2019 fiscal year or the foreseeable future. However, a separatedetermination must be made at the close of each taxable year as to whether we are a PFIC for that taxable year, and we cannot assure you that we will not be aPFIC for our 2020 fiscal year or any future taxable year. Under current law, a non-U.S. corporation will be considered a PFIC for any taxable year if either(a) at least 75% of its gross income is passive income or (b) at least 50% of the value of its assets, generally based on an average of the quarterly values of theassets during a taxable year, is attributable to assets that produce or are held for the production of passive income. PFIC status depends on the composition ofour assets and income and the value of our assets (which may be based in part on the value of our ordinary shares which may fluctuate), including, amongothers, a pro rata portion of the income and assets of each subsidiary in which we own, directly or indirectly, at least 25% by value of the subsidiary’s equityinterests, from time to time. Because we currently hold, and expect to continue to hold, a substantial amount of cash or cash equivalents, and because thecalculation of the value of our assets may be based in part on the value of our ordinary shares which may fluctuate and may fluctuate considerably given thatmarket prices of technology companies historically often have been volatile, we may be a PFIC for any taxable year. If we were treated as a PFIC for anytaxable year during which a U.S. holder held ordinary shares, certain adverse U.S. federal income tax consequences could apply for such U.S. holder.Changes in our United States federal income tax classification, or that of our subsidiaries, could result in adverse tax consequences to our 10% orgreater U.S. shareholders.The Tax Act signed on December 22, 2017 may have changed the consequences to U.S. shareholders that own, or are considered to own, as a result ofthe attribution rules, ten percent or more of the voting power or value of the stock of a non-U.S. corporation (a 10% U.S. shareholder) under the U.S. Federalincome tax law applicable to owners of U.S. controlled foreign corporations, or CFCs. Prior to the Tax Act, we did not believe that we, or any of our non-U.S. subsidiaries, were considered a CFC, which is a determination made daily basedon whether the 10% U.S. shareholders together own, or are considered to own as a result of the attribution rules, more than fifty percent of the voting power orvalue of a non-U.S. corporation. The Tax Act repealed Internal Revenue Code Section 958(b)(4), which, unless clarified in future regulations or otherguidance, may result in classification of certain of the Company’s foreign subsidiaries as CFCs with respect to any single 10% U.S. shareholder. This may bethe result without regard to whether 10% U.S. shareholders together own, directly or indirectly, more than fifty percent of the voting power or value of theCompany as was the case under prior rules. The repeal is effective as of the last taxable year of CFCs beginning before January 1, 2018 and for the taxableyear of 10% U.S. shareholders in which the CFCs' taxable year ends.Fluctuations in exchange rates between and among the currencies of the countries in which we do business may adversely affect our operatingresults.Our sales have been historically denominated in U.S. dollars. An increase in the value of the U.S. dollar relative to the currencies of the countries inwhich our end customers operate could impair the ability of our end customers to cost-effectively integrate our SoCs into their devices which may materiallyaffect the demand for our solutions and cause these end customers to reduce their orders, which would adversely affect our revenue and business. We mayexperience foreign exchange gains or losses due to the volatility of other currencies compared to the U.S. dollar. A significant portion of our solutions aresold to camera manufacturers located outside the United States, primarily in Asia. Sales to customers in Asia accounted for approximately 87%, 79% and 73%of our total revenue in fiscal years 2019, 2018 and 2017, respectively. Because most of our end customers or their ODM manufacturers are located in Asia, weanticipate that a majority of our future revenue will continue to come from sales to that region. Although a large percentage of our sales are made tocustomers in Asia, we believe that a significant number of the products designed by these customers and incorporating our SoCs are then sold to consumersglobally. In addition, if in the future we sell products or purchase inventory in currencies other than the U.S. dollar, our exposure to foreign currency riskcould become more significant.A significant number of our employees are located in Asia, principally Taiwan and China. Therefore, a portion of our payroll as well as certain otheroperating expenses are paid in currencies other than the U.S. dollar, such as the New Taiwan Dollar and the Chinese Yuan Renminbi. Our operating results aredenominated in U.S. dollars and the difference in exchange rates in one period compared to another may directly impact period-to-period comparisons of ouroperating results. Furthermore, currency exchange rates, particularly the exchange rates between the Chinese Yuan Renminbi and the U.S. dollar and betweenthe New Taiwan Dollar and the U.S. dollar, have been especially volatile in the recent past and these currency fluctuations may make it difficult for us topredict our operating results.37 We have not implemented any hedging strategies to mitigate risks related to the impact of fluctuations in currency exchange rates. Even if we were toimplement hedging strategies, not every exposure can be hedged and, where hedges are put in place based on expected foreign exchange exposure, they arebased on forecasts which may vary or which may later prove to have been inaccurate. Failure to hedge successfully or anticipate currency risks accuratelycould adversely affect our operating results.We may make acquisitions in the future that could disrupt our business, cause dilution to our shareholders, reduce our financial resources and harmour business.In the future, we may acquire other businesses, products or technologies. Other than our acquisition of VisLab S.r.l., or VisLab, in June 2015, we havenot made any acquisitions to date and do not have any agreements or commitments for any specific acquisition at this time. Our ability to make andsuccessfully integrate acquisitions is unproven. Our acquisition of VisLab and any future acquisitions may not strengthen our competitive position and maybe viewed negatively by our customers, financial markets or investors, and we may not achieve our goals in a timely manner, or at all. In addition, anyacquisitions we make could lead to difficulties in integrating personnel, technologies and operations from the acquired businesses and in retaining andmotivating key personnel from these businesses. Acquisitions may disrupt our ongoing operations, divert management from their primary responsibilities,subject us to additional liabilities, increase our expenses and adversely impact our business, operating results, financial condition and cash flows.Acquisitions may also reduce our cash available for operations and other uses, and could also result in an increase in amortization expense related toidentifiable assets acquired, potentially dilutive issuances of equity securities or the incurrence of debt, any of which could harm our business.We cannot predict our future capital needs, and we may not be able to obtain additional financing to fund our operations.We may need to raise additional funds in the future. Any required additional financing may not be available on terms acceptable to us, or at all. If weraise additional funds by issuing equity securities or convertible debt, investors may experience significant dilution of their ownership interest, and thenewly-issued securities may have rights senior to those of the holders of our ordinary shares. 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 operational flexibilityand would also require us to incur interest expense. If additional financing is not available when required or is not available on acceptable terms, we mayhave to scale back our operations or limit our production activities, and we may not be able to expand our business, develop or enhance our products, takeadvantage of business opportunities or respond to competitive pressures which could result in lower revenue and reduce the competitiveness of our products.Our marketable securities portfolio could experience a decline in market value, which could materially and adversely affect our financial results.In fiscal year 2019, we added an additional $100.0 million of capital in debt security investments. As of January 31, 2019, these securities hadapproximately $205.1 million in value. The investments consisted primarily of money market funds, certificates of deposit, commercial paper, asset-backedsecurities, U.S. government securities and debt securities of corporations which are focused on the preservation of our capital. We currently do not usederivative financial instruments to adjust our investment portfolio risk or income profile. These investments, as well as any cash deposited in bank accounts,are subject to general credit, liquidity, market and interest rate risks, which may be exacerbated by unusual events, such as the Eurozone crisis and the U.S.debt ceiling crisis, which affected various sectors of the financial markets and led to global credit and liquidity issues. If the global credit market continues toexperience volatility or deteriorates, our investment portfolio may be impacted and some or all of our investments may experience other-than-temporaryimpairment which could adversely impact our financial results and position.Risks Related to Ownership of Our Ordinary SharesThe market price of our ordinary shares may be volatile, which could cause the value of your investment to decline.Since our initial public offering in October 2012, the market price of our ordinary shares has been highly volatile. The trading price of our ordinaryshares is likely to remain volatile and could be subject to wide fluctuations in price in response to various factors, some of which are beyond our control.These factors include: •changes in financial estimates, including our ability to meet our future revenue and operating profit or loss projections; •fluctuations in our operating results or those of other semiconductor or comparable companies; •fluctuations in the economic performance or market valuations of companies perceived by investors to be comparable to us; •economic developments in the semiconductor industry as a whole;38 •general economic conditions and slow or negative growth of related markets; •announcements by us or our competitors of acquisitions, new products, significant contracts or orders, commercial relationships orcapital commitments; •our ability to develop and market new and enhanced solutions on a timely basis; •changes in the demand for our customers’ products; •commencement of or our involvement in litigation; •disruption to our operations; •any major change in our board of directors or management; •political or social conditions in the markets where we sell our products; •changes in governmental regulations; and •changes in earnings estimates or recommendations by securities analysts.In addition, the stock market in general, and the market for semiconductor and other technology companies in particular, have experienced extremeprice and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. These broad market andindustry factors may cause the market price of our ordinary shares to decrease, regardless of our actual operating performance. These trading price fluctuationsmay also make it more difficult for us to use our ordinary shares as a means to make acquisitions or to use options to purchase our ordinary shares to attractand retain employees. If the market price of our ordinary shares declines, you may not realize any return on your investment in us and may lose some or all ofyour investment. In addition, in the past, following periods of volatility in the overall market and the market price of a company’s securities, securities classaction litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion ofour management’s attention and resources.If securities analysts or industry analysts downgrade our ordinary shares, publish negative research or reports or fail to publish reports about ourbusiness, our stock price and trading volume could decline.The trading market for our ordinary shares will be influenced by the research and reports that industry or securities analysts publish about us, ourbusiness and our market. If one or more analysts adversely changes their recommendation regarding our stock or our competitors’ stock, our stock pricewould likely decline. If one or more analysts cease coverage of us or fail to regularly publish reports on us, we could lose visibility in the financial marketswhich in turn could cause our stock price or trading volume to decline.Our actual operating results may differ significantly from our guidance and investor expectations, which would likely cause our stock price todecline.From time to time, we may release guidance in our earnings releases, earnings conference calls or otherwise, regarding our future performance thatrepresent our management’s estimates as of the date of release. If given, this guidance, which will include forward-looking statements, will be based onprojections prepared by our management. Projections are based upon a number of assumptions and estimates that, while presented with numerical specificity,are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control. Theprincipal reason that we expect to release guidance is to provide a basis for our management to discuss our business outlook with analysts and investors. Withor without our guidance, analysts and other investors may publish expectations regarding our business, financial performance and results of operations. Wedo not accept any responsibility for any projections or reports published by any such third persons.Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions of the guidance furnished by us will notmaterialize or will vary significantly from actual results. If our actual performance does not meet or exceed our guidance or investor expectations, the tradingprice of our ordinary shares is likely to decline.The price of our ordinary shares could decrease as a result of shares being sold in the market.Sales of a substantial number of our ordinary shares in the public market, or the perception that these sales might occur, could cause the market priceof our ordinary shares to decline. We filed registration statements on Form S-8 under the Securities Act to register shares for issuance under our 2004 StockPlan, 2012 Equity Incentive Plan and the Amended and Restated 2012 Employee Stock Purchase Plan. Our 2012 Equity Incentive Plan and the Amended andRestated 2012 Employee Stock Purchase Plan provide for automatic increases in the shares reserved for issuance under these plans which could result inadditional dilution to our shareholders. These shares can be freely sold in the public market upon issuance and vesting, subject to restrictions provided underthe terms of the applicable plan and/or the option agreements entered into with option holders.39 We may also issue ordinary shares or securities convertible into ordinary shares from time to time in connection with a financing, acquisition orotherwise. Any such issuance could result in substantial dilution to our existing shareholders and cause the trading price of our stock to decline.We do not intend to pay dividends on our ordinary shares and, consequently, a shareholder’s ability to achieve a return on its investment willdepend on appreciation in the price of our ordinary shares.We have never declared or paid any cash dividends on our ordinary shares and do not currently intend to do so for the foreseeable future. We currentlyintend to invest our future earnings, if any, to fund our growth. Therefore, shareholders are not likely to receive any dividends on their ordinary shares for theforeseeable future and the success of an investment in our ordinary shares will depend upon any future appreciation in their value. There is no guarantee thatour ordinary shares will appreciate in value or even maintain the price at which our shareholders have purchased their shares. Investors seeking cashdividends should not purchase our ordinary shares.Provisions of our memorandum and articles of association and Cayman Islands corporate law may discourage or prevent an acquisition of uswhich could adversely affect the value of our ordinary shares.Provisions of our memorandum and articles of association and Cayman Islands law may have the effect of delaying or preventing a change of controlor changes in our management. These provisions include the following: •the division of our board of directors into three classes; •the right of our board of directors to elect a director to fill a vacancy created by the expansion of our board of directors or due to theresignation or departure of an existing board member; •prohibition of cumulative voting in the election of directors which would otherwise allow less than a majority of shareholders to electdirector candidates; •the requirement for the advance notice of nominations for election to our board of directors or for proposing matters that can be actedupon at a shareholders’ meeting; •the ability of our board of directors to issue, without shareholder approval, such amounts of preference shares as the board of directorsdeems necessary and appropriate with terms set by our board of directors, which rights could be senior to those of our ordinary shares; •the elimination of the rights of shareholders to call a special meeting of shareholders and to take action by written consent in lieu of ameeting; and •the required approval of a special resolution of the shareholders, being a two-thirds vote of shares held by shareholders present andvoting at a shareholder meeting, to alter or amend the provisions of our post-offering memorandum and articles of association.Holders of our ordinary shares may face difficulties in protecting their interests because we are incorporated under Cayman Islands law.Our corporate affairs are governed by our amended and restated memorandum and articles of association, by the Companies Law (as the same may besupplemented or amended from time to time) of the Cayman Islands and by the common law of the Cayman Islands. The rights of our shareholders and thefiduciary responsibilities of our directors under Cayman Islands law are not as clearly established as under statutes or judicial precedent in existence injurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the United States and providessignificantly less protection to investors. There is no legislation specifically dedicated to the rights of investors in securities and thus no statutorily definedprivate cause of action specific to investors such as those provided under the Securities Act or the Securities Exchange Act of 1934, as amended. In addition,shareholders of Cayman Islands companies may not have standing to initiate shareholder derivative actions in U.S. federal courts. Therefore, you may havemore difficulty in protecting your interests in the face of actions by our management, directors or controlling shareholders than would shareholders of acorporation incorporated in a jurisdiction in the United States due to the comparatively less developed nature of Cayman Islands law in this area.Shareholders of Cayman Islands exempted companies, such as our company, have no general rights under Cayman Islands law to inspect corporaterecords and accounts or to obtain copies of lists of shareholders of the company. Our directors have discretion under our articles of association to determinewhether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to ourshareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicitproxies from other shareholders in connection with a proxy contest.40 Subject to limited exceptions, under Cayman Islands law, a minority shareholder may not bring a derivative action against the board of directors.Holders of our ordinary shares may have difficulty obtaining or enforcing a judgment against us because we are incorporated under the laws of theCayman Islands.It may be difficult or impossible for you to bring an action against us in the Cayman Islands if you believe your rights have been infringed under U.S.securities laws. There is no statutory recognition in the Cayman Islands of judgments obtained in the United States, although the courts of the CaymanIslands will in certain circumstances recognize and enforce a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits.While there is no binding authority on this point, this is likely to include, in certain circumstances, a non-penal judgment of a United States court imposing amonetary award based on the civil liability provisions of the U.S. federal securities laws. The Grand Court of the Cayman Islands may stay proceedings ifconcurrent proceedings are being brought elsewhere. There is uncertainty as to whether the Grand Court of the Cayman Islands would recognize or enforcejudgments of United States courts obtained against us predicated upon the civil liability provisions of the securities laws of the United States or any statethereof and whether the Grand Court of the Cayman Islands would hear original actions brought in the Cayman Islands against us predicated upon thesecurities laws of the United States or any state thereof.

Prior to that date, there wasno public trading market for our ordinary shares. On March 15, 2019, there were 34 shareholders of record holding our ordinary shares. We cannot estimatethe number of beneficial owners since many brokers and other institutions hold our shares on behalf of shareholders.Share Performance GraphThis performance graph shall not be deemed to be “soliciting material” or “filed” or incorporated by reference in future filings with the Securities andExchange Commission, or subject to the liabilities of Section 18 of the Securities Exchange Act of 1934, as amended, or the Exchange Act, except as shall beexpressly set forth by specific reference in such filing.The following graph shows a comparison from February 1, 2014 through January 31, 2019 of the cumulative total return for our ordinary shares, theNASDAQ Composite Index and the Philadelphia Semiconductor Index.

OnJune 4, 2018, our Board of Directors authorized the repurchase of up to an additional $100.0 million of our ordinary shares over a twelve-month period commencing June 5, 2018. The repurchase program does not obligate us to acquire any particular amount of ordinary shares,and it may be suspended at any time at our discretion. Shares may be repurchased through open market purchases, 10b5-1 plans or privatelynegotiated transactions. Repurchases are funded using our working capital and any repurchased shares are recorded as authorized butunissued shares. As of January 31, 2019, we had repurchased an aggregate amount of $174.8 million of our ordinary shares, and we hadapproximately $31.9 million available to repurchase shares under the program through June 4, 2019.

Our historical results of operations are not necessarily indicative of results of operations to beexpected for any future period.Selected Consolidated Statements of Operations Data: Year Ended January 31, 2019 2018 2017 2016 2015 (in thousands, except per share data) Revenue $227,768 $295,402 $310,297 $316,373 $218,278 Income (loss) from operations $(40,420) $24,431 $60,363 $84,679 $51,861 Net income (loss) $(30,447) $18,852 $57,810 $76,508 $50,571 Net income (loss) per share attributable to ordinary shareholders: Basic $(0.93) $0.57 $1.77 $2.42 $1.70 Diluted $(0.93) $0.55 $1.68 $2.27 $1.57 Selected Consolidated Balance Sheet Data: As of January 31, 2019 2018 2017 2016 2015 (in thousands) Cash, cash equivalents and marketable securities $358,908 $434,591 $405,394 $307,893 $207,994 Working capital 370,566 440,047 414,139 320,828 229,889 Total assets 466,853 546,649 512,271 410,615 284,284 Total liabilities 47,364 64,462 57,637 61,159 47,073 Total shareholders' equity 419,489 482,187 454,634 349,456 237,211 On June 25, 2015, we completed the acquisition of VisLab S.r.l., for $30.0 million in cash. Of this total purchase price, $4.1 million was attributed tointangible assets, $25.3 million was attributed to goodwill, and $0.6 million was attributed to net assets acquired. A deferred tax liability of $1.3 millionrelated to the intangible assets was recorded to account for the difference between financial reporting and tax basis at the acquisition date, with an addition togoodwill. In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2015-17, Balance SheetClassification of Deferred Taxes. To simplify the presentation, the new guidance requires that all deferred tax assets and liabilities, along with any relatedvaluation allowance, be classified as noncurrent on the balance sheet. We adopted this standard in the fourth quarter of fiscal year 2016 on a prospectivebasis. The adoption of this new guidance resulted in all deferred tax assets and liabilities being classified as noncurrent in the consolidated balance sheets asof January 31, 2016. The prior periods were not restated for this presentation standard. Upon adoption of Accounting Standards Update No. 2015-05, Intangible - Goodwill and Other - Internal-Use Software (Subtopic 350-40), we accountfor a noncancelable on premise internal-use software license as the acquisition of an intangible asset and the incurrence of a liability to the extent that all or aportion of the software licensing fees are not paid on or before the license acquisition date. The intangible asset and related liability are recorded at netpresent value and interest expense is recorded over the payment term. As of January 31, 2019, there were $6.8 million of intangible assets, net of amortizationexpense, $4.9 million of current liabilities and $0.3 million of noncurrent liabilities related to these noncancelable internal-use software licenses recorded inthe consolidated balance sheets. Effective February 1, 2018, we adopted Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”)using a modified retrospective method with the cumulative effect recognized in the beginning retained earnings. The consolidated financial statements forthe fiscal year ended January 31, 2019 are reported under Topic 606, whereas the consolidated financial statements for the fiscal year 2018 and prior years arereported under Topic 605. See Note 2, "Revenue Recognition" of the Notes to Consolidated Financial Statements included in this report for more details.In the fourth quarter of fiscal year 2019, we released $8.0 million of valuation allowance related to prior year federal research and development creditcarryforwards, which resulted in a significant increase in deferred tax assets as of January 31, 2019. See Note 13, “Income Taxes” of the Notes to ConsolidatedFinancial Statements included in this report for more details.44 ITEM 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSOverviewWe are a leading developer of semiconductor processing solutions for video that enable high-definition, or HD, video capture, analysis, sharing anddisplay. A device that captures video includes four primary components: a lens, an image sensor, a video processor and storage memory. The video processorconverts raw video input into a format that can be stored and distributed efficiently and, in some cases, analyzes the video data to automate processes. Wecombine our processor design capabilities with our expertise in video and image processing, computer vision algorithms and software development toprovide a technology platform that is designed to be easily scalable across multiple applications in a variety of markets and enable rapid and efficientproduct development for our customers. Our system-on-a-chip, or SoC, designs fully integrate HD video processing, image processing, computer visionfunctionality, audio processing, and system functions onto a single chip, delivering exceptional video and image quality at high compression rates,differentiated functionality and low power consumption.Over the last several years, we have been expanding our development efforts on computer vision technology that complements our image processingand video compression technology. We believe that enhanced computer vision functionality is critical both to our current video markets, such as IP securitycamera, as well as future markets such as automotive OEM cameras for advanced driving assistance systems, or ADAS, and autonomous vehicles, androbotics. Our recent development efforts have focused on creating advanced computer vision algorithms and high-performance, low-power hardwareplatforms to enhance processing acceleration, which we refer to as our CVflow architecture. In 2017, we introduced our first computer vision semiconductorchip, the CV1 SoC. In 2018, we introduced three new computer vision-based SoCs to enable our customers to develop intelligent camera systems for a varietyof markets at different feature levels.Our revenue over the last three years has been generated primarily from sales of our solutions for incorporation into specialized video and imagecapture devices such as wearable sports cameras, automotive aftermarket cameras, IP security cameras and cameras incorporated into unmanned aerialvehicles, or UAVs or drones. Our revenue from several of these markets, however, has recently experienced significant declines. As a result, we believe thatour future revenue growth, if any, will significantly depend upon our ability to expand within the camera markets with our video and image processing SoCsolutions, particularly in the professional IP security and home security and monitoring camera markets, as well as emerging markets such as the OEMautomotive and robotics markets. We expect our research and development expenditures to increase in comparison to prior periods as we devote additionalresources to the development of innovative video and image processing solutions with increased functionality, such as computer vision capabilities, and aswe target new markets, such as the automotive OEM and robotics markets.We sell our solutions to leading original design manufacturers, or ODMs, and original equipment manufacturers, or OEMs, globally. We refer to ODMsas our customers and OEMs as our end customers, except as otherwise indicated or as the context otherwise requires. In the camera market, our solutionsenable the creation of high-quality video content in wearable cameras, automotive cameras, Internet Protocol, or IP, security cameras, for both professionaluse and home security and monitoring, unmanned aerial vehicle cameras, also referred to as UAVs or drones, and virtual reality cameras, also referred to as360° cameras. We also recently introduced, and continue to develop, solutions to address emerging markets, such as the incorporation of computer visionfunctionality for OEM automotive ADAS applications and robotics markets.Our sales cycles typically require a significant investment of time and a substantial expenditure of resources before we can realize revenue from thesale of our solutions, if any. Our typical sales cycle consists of a multi-month sales and development process involving our customers’ system designers andmanagement along with our sales personnel and software engineers. If successful, this process culminates in a customer’s decision to use our solutions in itssystem, which we refer to as a design win. Our sales efforts are typically directed to the OEM of the product that will incorporate our video and imageprocessing solution, but the eventual design and incorporation of our SoC into the product may be handled by an ODM on behalf of the OEM.Volume production may begin within six to 18 months or even longer after a design win, depending on the targeted market, the complexity of ourcustomer’s product and other factors upon which we may have little or no influence. Once one of our solutions has been incorporated into a customer’sdesign, we believe that our solution is likely to remain a component of the customer’s product for its life cycle because of the time and expense associatedwith redesigning a product or substituting an alternative solution. Conversely, a design loss to a competitor will likely preclude any opportunity for us togenerate future revenue from such customer’s product. Even if we obtain a design win and our SoC remains a component through the life cycle of acustomer’s product, the volume and timing of actual sales of our SoCs to the customer depend upon the production, release and market acceptance of thatproduct, none of which are within our control. A portable consumer device typically has a product life cycle of six to 18 months, while an IP security cameratypically has a product life cycle of 12 to 24 months. We anticipate that most OEM automotive products will have life cycles longer than two years.45 Fiscal Year 2019 Financial Highlights and Trends •We recorded revenue of $227.8 million in fiscal year 2019, a decrease of 22.9% as compared to fiscal year 2018. The decrease in revenue wasprimarily attributable to declines in revenue from wearable camera markets, including the sports camera, virtual reality and non-sports wearablecamera markets. The decrease was also attributable to lower revenue from the drone market as a result of a major customer in the drone marketshifting its consumer-based drones to competitive solutions, as well as continued weakness from smaller drone customers. The declines inrevenue in the wearable camera and drone markets were partially offset by revenue growth in the automotive and IP security camera markets.The revenue growth in the automotive camera market was primarily due to a significant increase in shipments of OEM automotive videorecorders in the Japan and China regions, offset by lower revenue from the automotive aftermarket. In the consumer IP security camera market,growth was led by the home security and monitoring market in the North America region, partially offset by a decline in revenue from the Asiaregion. The increased revenue in the IP security market was also attributable to revenue growth in the professional IP security camera marketoutside the China region, offset by a decline in revenue from a major Chinese customer. •We recorded an operating loss of $40.4 million in fiscal year 2019, as compared to operating income of $24.4 million in fiscal year 2018. Thedecrease in operating income was primarily due to decreased revenue and increased expenses incurred primarily in support of new applicationsfor the automotive OEM market as well as the development of computer vision-based solutions. The increase in expenses related primarily toincreased research and development headcount, chip tape-out fees and increased stock-based compensation expense. •We generated cash flows from operating activities of $24.5 million in fiscal year 2019, as compared to $85.4 million in fiscal year 2018. Thedecreased cash flows from operating activities were primarily due to decreased net income as a result of decreased revenue and increasedoperating expenses. The decrease in cash flows from operating activities also was attributable to decreased liabilities associated with the timingof payments to suppliers and decreased cash receipts associated with the timing of payments from customers. The decrease in cash flows fromoperating activities was partially offset by decreased inventory purchases associated with lower revenue in fiscal year 2019. •On June 4, 2018, our Board of Directors authorized the repurchase of up to an additional $100.0 million of our ordinary shares over a twelve-month period commencing June 5, 2018. We repurchased 2,485,992 shares for approximately $99.9 million in cash during the twelve monthsended January 31, 2019. As of January 31, 2019, we had repurchased a total of 3,985,876 shares for approximately $174.8 million in cash sincethe inception of repurchase programs in June 2016 and approximately $31.9 million remained available for repurchases under the currentrepurchase program through June 4, 2019. Repurchases are funded using working capital and any repurchased shares are recorded as authorizedbut unissued shares.Factors Affecting Our PerformanceDesign Wins. We closely monitor design wins by customer and end market. We consider design wins to be critical to our future success, although adesign win may not successfully materialize into revenue, and even if it does result in revenue, the amount generated by each design win can varysignificantly. Our long-term sales expectations are based on forecasts from customers and internal estimations of customer demand factoring in the expectedtime to market for end customer products incorporating our solutions and associated revenue potential. Our ability to accurately forecast demand, however,can be adversely affected by a number of factors, including inaccurate forecasting by our customers, miscalculations by our customers of their inventoryrequirements, changes in market conditions, adverse changes in our product order mix and fluctuating demand for our customers’ products.Pricing, Product Cost and Margin. Our pricing and margins depend on the volumes and features of the solutions we provide to our customers.Additionally, we make significant investments in new solutions for both cost improvements and new features that we expect to drive revenue and maintainmargins. In general, solutions incorporated into more complex configurations, such as those used in high-performance camera applications or, in the future,advanced driver assistance systems, have higher prices and higher gross margins as compared to solutions sold into lower-performing, more competitivecamera applications. Our average selling price can vary by market and application due to market-specific supply and demand, the maturation of productslaunched in previous years and the launch of new products by us or our competitors.We continually monitor the cost of our solutions. As we rely on third-party manufacturers for the manufacture of our products, we maintain a closerelationship with these suppliers to continually monitor production yields, component costs and design efficiencies.46 Ability to Capitalize on Computer Vision Trends. We expect that computer vision functionality will become an increasingly important requirement inmany of our current and future markets, including IP security, automotive, robotics, and UAV markets. As a result, we believe that our ability to developadvanced computer vision technology, enable and support customer product development in emerging applications, such as ADAS, advanced blind spotdetection, object detection, people recognition, retail analytics, and machine learning, and gain customer acceptance of our technology platform andsolutions, will be critical to our future success.Shifting Consumer Preferences. Our revenue is also subject to consumer preferences, regarding form factor and functionality, and how thosepreferences impact the video and image capture electronics that we support. For example, improved smartphone video capture capabilities led to the declineof video cameras aimed at the video and image capture market. The current video and image capture market is now characterized by a greater volume of morespecialized video and image capture devices that are less likely to be replaced with smartphones, such as wearable, IP security, UAV and automotive cameras.This increasing specialization of video capture devices has changed our customer base and end markets and has impacted our revenue. In the future, weexpect further changes will continue to impact our business performance in those markets.Continued Concentration of Revenue by End Market. Historically, our revenue has been significantly concentrated in a small number of end markets.In fiscal year 2010, the majority of our revenue came from the pocket video, camcorder and infrastructure markets. Since that time, we have developedtechnologies to provide solutions for new markets as they emerged, such as the wearable, IP security, UAV and automotive video recorder camera markets.Since fiscal year 2013, the wearable sports, professional IP security and UAV markets have been our largest end markets and sales into these marketscollectively generated the majority of our revenue. We believe, however, that expansion into new markets is required to facilitate revenue growth andcustomer diversification as our revenue from the wearable camera and UAV camera markets has recently declined. While we will continue to seek to expandour end market exposure, we anticipate that sales to a limited number of end markets will continue to account for a significant percentage of our total revenuefor the foreseeable future. Our end market concentration may cause our financial performance to fluctuate significantly from period to period based on thesuccess or failure of products that our SoCs are designed into as well as the overall growth or decline in the video capture markets in which we compete. Inaddition, we derive a significant portion of our revenue from a limited number of ODMs who build products on behalf of a limited number of OEMs and froma limited number of OEMs to whom we ship directly. We believe that our operating results for the foreseeable future will continue to depend on sales to arelatively small number of customers.Ability to Capitalize on Connectivity Trends. Mobile connected devices are ubiquitous today and play an increasingly prominent role in consumers’lives. The constant connectivity provided by these devices has created a demand for connected electronic peripherals such as video and image capturedevices. Our ability to capitalize on these trends by supporting our end customers in the development of connected peripherals that seamlessly cooperatewith other connected devices and allow consumers to distribute and share video and images with online media platforms is critical for our success. We haveadded wireless communication functionality into our solutions for wearable, IP security, UAV and automotive video recorder cameras. The combination ofour compression technology with wireless connectivity enables wireless video streaming and uploading of videos and images to the Internet. Our solutionsenable IP security camera systems to stream video content to either cloud infrastructure or connected mobile devices, and our solutions for wearable and UAVcameras allow consumers to quickly stream or upload video and images to social media platforms.Sales Volume. A typical camera design win that successfully launches into the marketplace can generate a wide range of sales volumes for oursolutions, depending on the end market demand for our customers’ products. This can depend on several factors, including the reputation of the endcustomer, market penetration, product capabilities, size of the end market that the product addresses and our end customers’ ability to sell their products. Incertain cases, we may provide volume discounts on sales of our solutions, which may be offset by lower manufacturing costs related to higher volumes. Ingeneral, our customers with greater market penetration and better branding tend to develop products that generate larger volumes over the product life cycle.Customer Product Life Cycle. We estimate our customers’ product life cycles based on the customer, type of product and end market. We typicallycommence commercial shipments from six to 18 months following a design win; however, in some markets, more lengthy product and development cyclesare possible, depending on the scope and nature of the project, such as in the automotive OEM market. A portable consumer device typically has a productlife cycle of six to 18 months, and an IP security camera typically has a product life cycle of 12 to 24 months. We anticipate that product development andproduct life cycles will typically be substantially longer in the OEM automotive and robotics markets.47 Results of OperationsThe following table sets forth our historical operating results for the periods indicated: Year Ended January 31, 2019 2018 2017 (dollars in thousands) Revenue $227,768 $295,402 $310,297 Cost of revenue 89,624 107,669 105,283 Gross profit 138,144 187,733 205,014 Operating expenses: Research and development 128,084 115,510 101,205 Selling, general and administrative 50,480 47,792 43,446 Total operating expenses 178,564 163,302 144,651 Income (loss) from operations (40,420) 24,431 60,363 Other income, net 5,868 1,298 518 Income (loss) before income taxes (34,552) 25,729 60,881 Provision (benefit) for income taxes (4,105) 6,877 3,071 Net income (loss) $(30,447) $18,852 $57,810 The following table sets forth our historical operating results as a percentage of revenue of each line item for the periods indicated: Year Ended January 31, 2019 2018 2017 Revenue 100% 100% 100%Cost of revenue 39 36 34 Gross profit 61 64 66 Operating expenses: Research and development 56 39 33 Selling, general and administrative 22 16 14 Total operating expenses 78 55 47 Income (loss) from operations (17) 9 19 Other income, net 2 — — Income (loss) before income taxes (15) 9 19 Provision (benefit) for income taxes (2) 2 1 Net income (loss) (13)% 7% 18% RevenueWe derive substantially all of our revenue from the sale of HD and Ultra HD video and image processing SoC solutions to OEMs and ODMs, eitherdirectly or through our distributors. In recent years, our SoC solutions have been primarily used in the camera markets, such as IP security, automotive videorecorder, drone and wearable cameras. Although we expect these camera markets, in particular the IP security camera market, to continue to generate revenuefor the foreseeable future, we have recently introduced new SoCs targeting emerging computer vision applications in the OEM automotive and roboticsmarkets. We derive a substantial portion of our revenue from sales made indirectly through one of our distributors, Wintech Microelectronics Co., Ltd., orWintech, and directly to one of our ODM customers, Chicony Electronics Co., Ltd., or Chicony.We have historically experienced seasonal fluctuations in our quarterly revenue with our third fiscal quarter normally being the highest revenuequarter. This fluctuation has been driven primarily by increased sales in consumer camera markets as our customers build inventories in preparation for theholiday shopping season. Due to experienced declines in demand for our solutions in several consumer camera markets, including wearable camera, virtualreality and drone markets, the seasonal impact on quarterly revenue was not significant in fiscal year 2019. More generally, our average selling pricesfluctuate based on the mix of our solutions sold in a period which reflects the impact of both changes in unit sales of existing solutions as well as theintroduction and sales of new solutions. Our solutions are typically characterized by a life cycle that begins with higher average selling prices and lowervolumes, followed by broader market adoption, higher volumes and average selling prices that are lower than initial levels.48 The end markets into which we sell our products have seen significant changes as consumer preferences have evolved in response to newtechnologies. As a result, the composition and timing of our revenue may differ meaningfully during periods of technology or consumer preference changes.We expect shifts in consumer use of video capture to continue to change over time, as computer vision specialized use cases emerge and video capturecontinues to proliferate.Cost of Revenue and Gross MarginCost of revenue includes the cost of materials such as wafers processed by third-party foundries, costs associated with packaging, assembly andtesting, and our manufacturing support operations such as logistics, planning and quality assurance. Cost of revenue also includes indirect costs such aswarranty, inventory valuation reserves and other general overhead costs.We expect that our gross margin may fluctuate from period to period as a result of changes in average selling price, product mix and the introductionof new products by us or our competitors. In general, solutions incorporated into more complex configurations, such as those used in high-performancecameras, and in the future advanced automotive OEM applications, have had or are expected to have higher prices and higher gross margins, as compared tosolutions sold into the lower-performance, more competitive camera applications. As semiconductor products mature and unit volumes sold to customersincrease, their average selling prices typically decline. These declines may be paired with improvements in manufacturing yields and lower wafer, packagingand test costs, which offset some of the margin reduction that could result from lower selling prices. We believe that our gross margin will decline in thefuture as we continue to penetrate the highly competitive camera market and, in particular, the IP security market.Research and DevelopmentResearch and development expense consists primarily of personnel costs, including salaries, stock-based compensation and employee benefits. Theexpense also includes costs of development incurred in connection with our collaborations with our foundry vendors, costs of licensing intellectual propertyfrom third parties for product development, costs of development for software and hardware tools, cost of fabrication of mask sets for prototype products, andallocated depreciation and facility expenses. All research and development costs are expensed as incurred. We expect our research and development expenseto increase in absolute dollars as we continue to enhance and expand our product features and offerings and increase headcount for new SoC developmentand development of computer vision technology, especially for the OEM automotive market.Selling, General and AdministrativeSelling, general and administrative expense consists primarily of personnel costs, including salaries, stock-based compensation and employee benefitsfor our sales, marketing, finance, human resources, information technology and administrative personnel. The expense also includes professional servicecosts related to accounting, tax, legal services, and allocated depreciation and facility expenses. We expect our selling, general and administrative expense toincrease in absolute dollars as we continue to maintain the infrastructure and expand the size of our sales and marketing organization to support our businessstrategy of addressing new opportunities with our computer vision technology.Other Income, NetOther income consists primarily of interest income from investments in debt securities, interest income from deposits with financial institutions and infiscal year 2019 a grant from a foreign government, net of interest expense incurred for intangible assets purchased and gains and losses from foreign currencytransactions and remeasurements.Provision (Benefit) for Income TaxesWe are incorporated and domiciled in the Cayman Islands and also conduct business in several countries such as the United States, China, Taiwan,Hong Kong, Italy, South Korea and Japan, and we are subject to taxation in those jurisdictions. Our worldwide operating income is subject to varying taxrates, and our effective tax rate is highly dependent upon the geographic distribution of our earnings or losses and the tax laws and regulations in eachgeographical region. It is also subject to fluctuation from changes in the valuation of our deferred tax assets and liabilities; tax benefits from excess stock-based compensation deductions; transfer pricing adjustments and the tax effects of nondeductible compensation. We have historically had lower effective taxrates as a substantial percentage of our operations are conducted in lower-tax jurisdictions. If our operational structure was to change in such a manner thatwould increase the amount of operating income subject to taxation in higher-tax jurisdictions, or if we were to commence operations in jurisdictionsassessing relatively higher tax rates, our effective tax rate could fluctuate significantly on a quarterly basis and/or be adversely affected.49 Significant judgment is required in evaluating our uncertain tax positions and determining our provision for income taxes. Although we believe ourreserves are reasonable, no assurance can be given that the final tax outcome of these matters will not be different from that which is reflected in our historicalprovision for income taxes and accruals. We adjust these reserves in light of changing facts and circumstances, such as the closing of a tax audit or therefinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will impact theprovision for income taxes in the period in which such determination is made. The provision for income taxes includes the impact of uncertain tax positionreserves and changes to reserves that are considered appropriate, as well as the related net interest and penalties.Significant judgment is also required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuationallowance, we consider all available evidence, including past operating results, estimates of future taxable income, and the feasibility of tax planningstrategies. In the event that we change our determination as to the amount of deferred tax assets that can be realized, we will adjust our valuation allowancewith a corresponding impact to the provision for income taxes in the period in which such determination is made.Comparison of the Fiscal Years Ended January 31, 2019, 2018 and 2017Revenue Change Year Ended January 31, 2019 2018 2019 2018 2017 Amount % Amount % (dollars in thousands) Revenue $227,768 $295,402 $310,297 $(67,634) (22.9)% $(14,895) (4.8)% Revenue decreased for fiscal year 2019, as compared to fiscal year 2018, primarily due to declines in revenue from wearable camera markets, includingthe sports camera, virtual reality and non-sports wearable camera markets. The decrease was also attributable to lower revenue from the drone market as aresult of a major customer in the drone market shifting its consumer-based drones to competitive solutions, as well as continued weakness from smaller dronecustomers. The declines in revenue in the wearable camera and drone markets were partially offset by revenue growth in the automotive and IP securitycamera markets. The revenue growth in the automotive camera market was primarily due to a significant increase in shipments of OEM automotive videorecorders in the Japan and China regions, offset by lower revenue from the automotive aftermarket. In the consumer IP security camera market, growth was ledby the home security and monitoring market in the North America region, partially offset by a decline in revenue from the Asia region. The increased revenuein the IP security market was also attributable to revenue growth in the professional IP security camera market outside the China region, offset by a decline inrevenue from a major Chinese customer. Revenue decreased for fiscal year 2018, as compared to fiscal year 2017, primarily due to our major customer in the sports camera market, GoPro,incorporating a competing solution into one of its recently released mainstream camera models that significantly reduced our sales to GoPro in fiscal year2018. Compared to fiscal year 2017, revenue from GoPro declined by 50.3% from $74.9 million in fiscal year 2017 to $37.2 million in fiscal year 2018. Thedecrease was also attributable to a decline in revenues from DJI in the drone market as the customer’s product mix shifted to non-Ambarella-based drones, aswell as continued weakness from smaller consumer drone customers. The declined revenues in sports camera and drone markets were partially offset by strongrevenue growth in the IP security, automotive and non-sports wearable camera markets. Revenue growth in the IP security camera market was primarily due tosolid performance in the home security and monitoring camera market. In the automotive camera market, an increase in shipments of OEM automotive videorecorders plus growth in shipments for the automotive aftermarket resulted in strong revenue growth in that market in fiscal year 2018. In fiscal year 2018,infrastructure revenue continued to decline as a percentage of total revenue from 2.4% in fiscal year 2017 to 1.6% in fiscal year 2018 due to continued weakmarket conditions in the United States and Europe as investment in network upgrades to the new H.265 video compression technology was delayed.Cost of Revenue and Gross Margin Change Year Ended January 31, 2019 2018 2019 2018 2017 Amount % Amount % (dollars in thousands) Cost of revenue $89,624 $107,669 $105,283 $(18,045) (16.8)% $2,386 2.3%Gross profit 138,144 187,733 205,014 (49,589) (26.4)% (17,281) (8.4)%Gross margin 60.7% 63.6% 66.1% — (2.9)% — (2.5)% 50 Cost of revenue decreased for fiscal year 2019, as compared to fiscal year 2018, primarily due to lower shipments of higher cost SoCs associated withlower revenue in the wearable camera and drone markets. The decrease in cost of revenue was partially offset by increased shipments of SoCs for the IPsecurity camera and automotive OEM markets. Cost of revenue increased for fiscal year 2018, as compared to fiscal year 2017, primarily due to an increase in the number of SoC shipments, though atlower gross margins. The increase was also attributable to approximately $2.9 million of cost benefit received in fiscal year 2017 from the recovery and saleof previously written down inventory that did not recur in fiscal year 2018. Gross margin continuously decreased, as compared to the prior fiscal years, primarily due to an increase in the percentage of our total revenue that wasderived from the lower gross margin IP security camera market combined with the decline in revenue from the higher gross margin sports camera and dronemarkets.Research and Development Change Year Ended January 31, 2019 2018 2019 2018 2017 Amount % Amount % (dollars in thousands) Research and development $128,084 $115,510 $101,205 $12,574 10.9% $14,305 14.1% Research and development expense increased for fiscal year 2019, as compared to fiscal year 2018, primarily due to increases in engineeringheadcount and chip development cost associated with the computer vision technology development for our current markets, as well as new markets such asthe automotive OEM and robotics markets. Our engineering headcount increased to 554 at January 31, 2019 compared to 519 at January 31, 2018, whichresulted in an increase in salary-related expenses of approximately $7.0 million in fiscal year 2019. The increased research and development expense wasalso attributable to additional stock-based compensation expense of approximately $2.9 million in fiscal year 2019, as a result of the issuance of options andrestricted stock units for newly hired employees, our annual evergreen stock program for existing employees, and performance stock program for executives.SoC development related costs increased by approximately $3.8 million for fiscal year 2019, as compared to fiscal year 2018, due to the timing and numberof chips in development. Research and development expense increased for fiscal year 2018, as compared to fiscal year 2017, primarily due to the increase in engineeringheadcount associated with new SoC hardware and software development, principally in support of our computer vision technology for our current markets aswell as new markets such as the automotive OEM and robotics markets. Our research and development engineering headcount increased to 519 at January 31,2018 compared to 491 at January 31, 2017. The increased engineering headcount resulted in increases in salary-related expenses of approximately $5.2million in fiscal year 2018. The increased research and development expense was also attributable to additional stock-based compensation expense ofapproximately $4.8 million in fiscal year 2018, as a result of the issuance of options and restricted stock units for newly hired employees, our annualevergreen stock program for existing employees and performance stock program for executives. SoC development related costs increased by approximately$3.8 million for fiscal year 2018 due to the timing and number of chips in development.Selling, General and Administrative Change Year Ended January 31, 2019 2018 2019 2018 2017 Amount % Amount % (dollars in thousands) Selling, general and administrative $50,480 $47,792 $43,446 $2,688 5.6% $4,346 10.0% Selling, general and administrative expense increased for fiscal year 2019, as compared to fiscal year 2018, primarily due to increased headcount tosupport our business development in IP security, automotive OEM and robotics markets, which resulted in an increase in salary-related expenses ofapproximately $1.8 million in fiscal year 2019. The increase was also attributable to additional stock-based compensation expense of approximately $1.1million as a result of the issuance of options and restricted stock units for newly hired employees, our annual evergreen stock program for existing employeesand performance stock program for executives. 51 Selling, general and administrative expense increased for fiscal year 2018, as compared to fiscal year 2017, primarily due to increased stock-basedcompensation expense of approximately $3.0 million as a result of the issuance of options and restricted stock units for newly hired employees, our annualevergreen stock program for existing employees and performance stock program for executives. The increase was also attributable to approximately $1.2million of additional expenditures on outside professional services in fiscal year 2018 to support our business.Other Income, Net Change Year Ended January 31, 2019 2018 2019 2018 2017 Amount % Amount % (dollars in thousands) Other income, net $5,868 $1,298 $518 $4,570 352.1% $780 150.6% The increase in other income, net, for fiscal year 2019, as compared to fiscal year 2018, was primarily due to an aggregate of approximately $2.7million of additional interest and other income from our deposits and debt security investments. The increase is primarily the result of larger investedbalances, interest rate increases and debt securities purchased at discounts. In fiscal year 2019, we added an additional $100.0 million of capital in debtsecurity investments. The increase was also attributable to a grant of approximately $1.8 million from a foreign government related to research anddevelopment activities which can, at our discretion, be used to satisfy certain types of future tax or social insurance liabilities. The increase in other income, net, for fiscal year 2018, as compared to fiscal year 2017, was primarily due to approximately $579,000 of additionalinterest income from our deposits with financial institutions and approximately $498,000 of additional interest income from marketable security investments.The increase was partially offset by approximately $281,000 interest expense from software license liabilities.Provision (Benefit) for Income Taxes Change Year Ended January 31, 2019 2018 2019 2018 2017 Amount % Amount % (dollars in thousands)Provision (benefit) for income taxes $(4,105) $6,877 $3,071 $(10,982) (159.7)% $3,806 123.9%Effective tax rate 12% 27% 5% — (15)% — 22% Income tax expense and the effective tax rate decreased in fiscal 2019, as compared to fiscal year 2018, primarily due to the release of $8.0 million ofvaluation allowance related to prior year federal research and development credit carryforwards, as well as the reduction in the U.S. federal statutory rate from35% to 21%, partially offset by a decrease in the proportion of profits generated in lower tax jurisdictions and losses incurred in jurisdictions for which wewere not able to recognize a related tax benefit. Income tax expense and effective tax rate increased in fiscal year 2018, as compared to fiscal year 2017, primarily due to an unfavorable change in ourgeographic mix of profits as well as an increase in deferred tax expense of $2.3 million as a result of the decrease in the corporate tax rate from 35% to 21%associated with the enactment of the Tax Cuts and Job Act of 2017. The increase was also attributable to approximately $3.0 million increase in non-deductible stock-based compensation expense. These increases were offset by a $1.9 million reduction in the amount of tax expense recorded for changes invaluation allowance, as the Company’s valuation allowance did not change significantly in fiscal year 2018.52 Liquidity and Capital ResourcesCash FlowsThe following table summarizes our cash flows for the periods indicated: Year Ended January 31, 2019 2018 2017 (in thousands) Net cash provided by operating activities $24,472 $85,404 $113,316 Net cash used in investing activities (79,142) (9,600) (45,734)Net cash used in financing activities (97,953) (52,003) (12,764)Net increase (decrease) in cash, cash equivalents and restricted cash $(152,623) $23,801 $54,818 Net Cash Provided by Operating ActivitiesFiscal year 2019 compared to fiscal year 2018: Cash provided by operating activities decreased primarily due to decreased net income as a result oflower revenue and increased operating expenses. The decrease in cash flows from operating activities also was attributable to decreased liabilities associatedwith the timing of payments to suppliers and decreased cash receipts associated with the timing of payments from customers. The decrease was partially offsetby decreased inventory purchases associated with lower revenue in fiscal year 2019.Fiscal year 2018 compared to fiscal year 2017: Cash provided by operating activities decreased primarily due to decreased net income as a result oflower revenue and increased operating expenses adjusted for increased non-cash stock-based compensation expense. The decrease in cash flows fromoperating activities also was attributable to decreased liabilities associated with the timing of payments to suppliers and decreased deferred revenue. Thedecrease was partially offset by increased cash receipts associated with the timing of payments from our customers.Net Cash Used in Investing ActivitiesFiscal year 2019 compared to fiscal year 2018: Net cash used in investing activities increased primarily due to approximately $133.0 million ofadditional investments in debt securities. The increased cash used in investing activities was partially offset by an increase of approximately $62.7 million incash receipts from the sale and maturity of debt securities.Fiscal year 2018 compared to fiscal year 2017: Net cash used in investing activities decreased primarily due to a reduction of approximately $40.7million of investments in debt securities compared to the prior fiscal year. The decreased investment expenditure was partially offset by approximately $3.6million of fewer cash receipts from the sale and maturity of debt securities and approximately $1.0 million of additional investment in property andequipment in fiscal year 2018 compared to the prior fiscal year.Net Cash Used in Financing ActivitiesFiscal year 2019 compared to fiscal year 2018: Net cash used in financing activities increased primarily due to additional payments of $45.1 millionin cash for the repurchase of our ordinary shares under a stock repurchase program. The increased cash used in financing activities also was attributable toadditional payments of $0.4 million in cash for intangible assets purchased, primarily software licenses, as well as approximately $0.4 million less in cashproceeds from option exercises in fiscal year 2019. Fiscal year 2018 compared to fiscal year 2017: Net cash used in financing activities increased primarily due to additional payments of $34.6 millionin cash for the repurchase of our ordinary shares under our stock repurchase program, as well as additional payments of $4.3 million in cash for intangibleassets, primarily software licenses, purchased in fiscal year 2018 compared to the prior fiscal year.Stock Repurchase ProgramOn June 4, 2018, our Board of Directors authorized the repurchase of up to an additional $100.0 million of our ordinary shares over a twelve-monthperiod commencing June 5, 2018. Since the inception of the repurchase programs in June 2016, a total of $225.0 million has been authorized, and we haverepurchased a total of 3,985,876 shares for approximately $174.8 million in cash. As of January 31, 2019, approximately $31.9 million remained availablefor repurchases under the current repurchase program through June 4, 2019. Repurchases under the program may be made from time-to-time through openmarket purchases, 10b5-1 plans or privately negotiated transactions subject to market conditions, applicable legal requirements and other relevant factors.The repurchase program does not obligate us to acquire any particular amount of ordinary shares, and it may be suspended at any time at the company'sdiscretion. Repurchases are funded using working capital and any repurchased shares are recorded as authorized but unissued shares.53 Sources of LiquidityAs of January 31, 2019 and 2018, we had cash, cash equivalents and marketable debt securities of approximately $358.9 million and $434.6 million,respectively. During the past three fiscal years, we invested a total of $200.0 million in highly liquid, short-term marketable debt securities. As of January 31,2019, these securities had a fair value of approximately $205.1 million with insignificant unrealized gains caused by fluctuations in market value andinterest rates. We hold these investments as available-for-sale securities and mark them to market.Operating and Capital Expenditure RequirementsAs of January 31, 2019, we had cash, cash equivalents and marketable securities of approximately $358.9 million. We believe that our existing cashbalances will be sufficient to meet our anticipated cash requirements through at least the next 12 months. In the future, we expect our operating and capitalexpenditures to increase as we increase headcount, expand our business activities, and implement and enhance our information technology platforms. As weexpand our operations, we may require more working capital. If our available cash balances are insufficient to satisfy our future liquidity requirements, wemay seek to sell equity or convertible debt securities or borrow funds commercially. The sale of equity and convertible debt securities may result in dilutionto our shareholders and those securities may have rights senior to those of our ordinary shares. If we raise additional funds through the issuance of convertibledebt securities, these securities could contain covenants that would restrict our operations. We may require additional capital beyond our currentlyanticipated amounts. Additional capital may not be available to us on reasonable terms, or at all.Our short- term and long-term capital requirements will depend on many factors, including the following: •our ability to generate cash from operations; •our ability to control our costs; •the expansion of our research and development of new technologies and products to address new markets and applications; •the emergence of competing or complementary technologies or products; •the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights or participating inlitigation-related activities; and •our acquisition of complementary businesses, products and technologies.Contractual Obligations, Commitments and ContingenciesThe following table summarizes our outstanding contractual obligations as of January 31, 2019: Payment Due by Period as of January 31, 2019 (in thousands) Less than More than All Total 1 Year 1-3 Years 3-5 Years 5 Years Other Contractual Obligations Facility obligations under operating leases (1) $4,854 $2,592 $1,396 $290 $576 $— Technology licenses (2) 5,293 4,983 310 — — — Purchase obligations (3) 28,206 28,206 — — — — Unrecognized tax benefits, including interest (4) 6,732 — — — — 6,732 Total $45,085 $35,781 $1,706 $290 $576 $6,732 (1)Facility obligations under operating leases primarily represent facilities with initial lease terms in excess of one year. They are located in UnitedStates, Taiwan, China, Hong Kong, Japan and Italy.(2)Technology license obligations represent future cash payments for noncancelable internal-use software licenses which are used in product design.(3)Purchase obligations consist primarily of inventory purchase obligations with our independent contract manufacturers.(4)Unrecognized tax benefits, including interest, represent our liabilities for uncertain tax positions as of January 31, 2019. We are unable to reasonablyestimate the timing of payments in individual years due to uncertainties in the timing of the effective settlement of tax positions.54 Stock Options and Restricted Stock UnitsGrants of stock-based awards are key components of the compensation packages we provide to attract and retain certain employees to align theirinterests with the interests of existing shareholders. We recognize that these stock-based awards will dilute existing shareholders and have sought to limit thenumber of shares granted while providing competitive compensation packages. As of January 31, 2019, we had a total of 3.8 million ordinary shares subjectto outstanding stock options and unvested restricted stock and restricted stock units, which will potentially dilute our earnings per share. This potentialdilution will only result if outstanding options vest and are exercised and restricted stock and restricted stock units vest and are settled. As of January 31,2019, 55% of our outstanding options had exercise prices less than the then market price of our ordinary shares on such date.Off-Balance Sheet ArrangementsAs of January 31, 2019, we did not engage in any off-balance sheet arrangements, including the use of structured finance, special purpose entities orvariable interest entities.Recent Accounting PronouncementsSee Note 1, “Organization and Summary of Significant Accounting Policies—Recent Accounting Pronouncements” of the Notes to the ConsolidatedFinancial Statements, included in Part IV, Item 15 of this report, for a full description of recent accounting standards, including the respective dates ofadoption and effects on our consolidated financial position, results of operations and cash flows.Critical Accounting Policies and Significant Management EstimatesThe preparation of audited consolidated financial statements in conformity with U.S. generally accepted accounting principles, or GAAP, requires usto make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities atthe date of the financial statements and the reported amounts of revenue and expense during the reported periods. On an ongoing basis, we evaluate ourestimates and assumptions, including those related to (i) the collectability of accounts receivable; (ii) write down of excess and obsolete inventories; (iii)intangible assets and goodwill; (iv) the estimated useful lives of long-lived assets; (v) impairment of long-lived assets and financial instruments; (vi) warrantyobligations; (vii) the valuation of stock-based compensation awards and financial instruments; (viii) the probability of performance objectives achievement;(ix) the realization of tax assets and estimates of tax liabilities, including reserves for uncertain tax positions; and (x) the recognition and disclosure ofcontingent liabilities. These estimates and assumptions are based on historical experience and on various other factors which we believe to be reasonableunder the circumstances. We may engage third-party valuation specialists to assist with estimates related to the valuation of financial instruments, assets andstock awards associated with various contractual arrangements. Such estimates often require the selection of appropriate valuation methodologies andsignificant judgment. Actual results could differ from these estimates under different assumptions or circumstances and such differences could be material.We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate tothe more significant areas involving management’s judgment and estimates:Revenue RecognitionEffective February 1, 2018, we adopted Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC606”), using the modified retrospective method applied to those contracts that were not completed as of February 1, 2018. Results for reporting periodsbeginning after February 1, 2018 are presented under ASC 606. Prior period amounts are not adjusted and continue to be reported in accordance with ourhistoric accounting under ASC Topic 605, Revenue Recognition (“ASC 605”). The most significant impacts of this new guidance for us relate to thedetermination of transaction price and the timing of revenue recognition for transactions with distributors. As a result, we now recognize product revenueupon shipment and transfer of control to distributors (known as “sell-in” revenue recognition) rather than shipment to the end customers (known as “sell-through” revenue recognition) based on our estimate of the consideration we expect to receive. Revenue recognition is evaluated through the following fivesteps: (i) identification of the contract, or contracts, with a customer; (ii) identification of the performance obligations in the contract; (iii) determination ofthe transaction price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when or as aperformance obligation is satisfied.55 The sale of semiconductor products accounts for the substantial majority of our consolidated revenue. Sales agreements with customers are renewableperiodically and contain terms and conditions with respect to payment, delivery, warranty, supply and other rights. We consider an accepted customerpurchase order, governed by sales agreement, to be the contract with the customer. For each contract, we consider the promise to transfer tangible products tobe the identified performance obligation. Product sales contracts may include volume-based tiered pricing or rebates that are fulfilled in cash or product. Indetermining the transaction price, we accounts for the right of returns, cash rebates, commissions and other pricing adjustments as variable consideration andestimate these amounts based on the expected amount to be provided to customers and reduce the revenue recognized. We estimate sales returns and rebatesbased on our historical patterns of return and pricing credits. As our standard payment terms are 30 days to 60 days, the contracts have no financingcomponent. Under ASC 606, we estimate the total consideration to be received by using the expected value method for each contract, compute weightedaverage selling price for each unit shipped in cases where there is a material right due to the presence of volume-based tiered pricing, allocate the totalconsideration between the identified performance obligations, and recognize revenue when control of our goods and services is transferred to our customers.We consider product control to be transferred at shipment or delivery because we have a present right to payment at that time, the customer has legal title tothe asset, we have transferred physical possession of the asset, and the customer has significant risk and rewards of ownership of the asset.We also enter into fixed-price engineering service agreements with certain customers. These agreements may include multiple performanceobligations, such as software development services, licensing of intellectual property and post-contract customer support, or PCS. These multipleperformance obligations are highly interdependent, highly interrelated, are typically not sold separately and do not have standalone selling prices. They areall inputs to generate one combined output which is incorporating our SoC into the customer’s product. Accordingly, we determine that they are notseparately identifiable and shall be treated as a single performance obligation. Customers usually pay based on milestones achieved. Because paymentsreceived do not correspond directly with the value of our performance to date, for fixed-price engineering services arrangements, revenue is recognized usingthe time-based straight line method, which best depicts our performance toward complete satisfaction of the performance obligation based on the nature ofsuch professional services. Revenues from engineering service agreements were not material for the fiscal years ended January 31, 2019, 2018 and 2017,respectively. Cash Equivalents and Marketable Debt SecuritiesWe consider all highly liquid debt security investments with original maturities of less than three months at the time of purchase to be cashequivalents. Debt security investments that are highly liquid with original maturities at the time of purchase greater than three months are considered asmarketable debt securities.We classify these investments as “available-for-sale” securities carried at fair value, based on quoted market prices of similar assets, with theunrealized gains or losses reported, net of tax, as a separate component of shareholders’ equity and included in accumulated other comprehensive income(loss) in the consolidated balance sheets. The amortization of premiums and accretion of discounts and the realized gains and losses are both recorded inother income, net in the consolidated statements of operations. We review our investments for possible other-than-temporary impairments on a regular basis.If any loss on investment is believed to be other-than-temporary, a charge will be recorded and a new cost basis in the investment will be established. Inevaluating whether a loss on a security is other-than-temporary, we consider the following factors: 1) general market conditions, 2) the duration and extent towhich the fair value is less than cost, 3) our intent and ability to hold the investment.For securities in an unrealized loss position which is deemed to be other-than-temporary, the difference between the security’s then-current amortizedcost basis and fair value is separated into (i) the amount of the impairment related to the credit loss (i.e., the credit loss component) and (ii) the amount of theimpairment related to all other factors (i.e., the non-credit loss component). The credit loss component is recognized in earnings. The non-credit losscomponent is recognized in accumulated other comprehensive loss. Due to the relative short term nature of the investments, there have been no other-than-temporary impairments recorded to date.Inventory ValuationWe record inventories at the lower of cost or net realizable value. The cost includes materials and other production costs and is computed usingstandard cost on a first-in, first-out basis. Inventory reserves are recorded for estimated obsolescence or unmarketable inventories based on forecast of futuredemand and market conditions. Any adjustments to reduce the cost of inventories to their net realizable value are recognized in earnings in the currentperiod. Once inventory is written down, a new accounting cost basis is established and, accordingly, any associated reserve is not released until the inventoryis sold or scrapped. There were no material inventory losses recognized for the fiscal years ended January 31, 2019, 2018 and 2017, respectively.56 Noncancelable Software LicenseWe account for a noncancelable on premise internal-use software license as the acquisition of an intangible asset and the incurrence of a liability tothe extent that all or a portion of the software licensing fees are not paid on or before the license acquisition date. The intangible asset and related liability arerecorded at net present value and interest expense is recorded over the payment term.Goodwill and In-Process Research and DevelopmentGoodwill and in-process research and development (“IPR&D”) are required to be tested for impairment at least annually in the fourth fiscal quarter orsooner whenever events or changes in circumstances indicate that the assets may be impaired. We have a single reporting unit for goodwill impairment testpurposes based on our business and reporting structure.We do not amortize goodwill. Acquired IPR&D is capitalized at fair value as an intangible asset and amortization commences upon completion of theunderlying projects. When a project underlying reported IPR&D is completed, the corresponding amount of IPR&D is reclassified as an amortizablepurchased intangible asset and is amortized over its estimated useful life.Stock-Based CompensationWe measure stock-based compensation for equity awards granted to employees and directors based on the estimated fair value on the grant date, andrecognize that compensation as expense using the straight-line attribution method for service condition awards or using the graded-vesting attributionmethod for awards with performance conditions over the requisite service period, which is typically the vesting period of each award. We determine the fairvalue of restricted stock and restricted stock units with service or performance conditions based on the fair market value of our ordinary shares on the grantdate. We use the Black-Scholes option pricing model to determine the fair value of stock options. Determining the fair value of stock options on the grantdate requires the input of various assumptions, including stock price of the underlying ordinary share, the exercise price of the stock option, expectedvolatility, expected term, risk-free interest rate and dividend rate. In prior fiscal years, the expected term was calculated using the simplified method, and theexpected volatility was calculated based on the weighted average of historical volatilities of our own stock price and the share prices of similar companiesthat are publicly available for a period commensurate with the expected term. Starting from fiscal year 2019, we calculate expected volatility based on ourown historical stock price for a period commensurate with the expected term, which is computed based on our own historical exercise behavior. The risk-freeinterest rate is derived from an average of the U.S. Treasury constant maturity rates for the respective periods most closely commensurate with the expectedterm. The expected dividend yield is zero because we have not historically paid dividends and have no present intention to pay dividends. We use theLattice pricing model and perform Monte Carlo Simulation to evaluate the fair value of awards with market conditions, including assumptions of historicalvolatility and risk-free interest rate commensurate with the vesting term. Upon adoption of ASU 2016-09, we elect to account for forfeitures as they occur.Net Income (Loss) Per Ordinary ShareBasic earnings (losses) per share is computed by dividing net income (loss) available to ordinary shareholders by the weighted-average number ofordinary shares outstanding during the period. Diluted earnings (losses) per share is computed by dividing net income (loss) available to ordinaryshareholders by the weighted-average number of ordinary shares outstanding during the period increased to include the number of additional ordinary sharesthat would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options,shares to be purchased under the Company’s employee stock purchase plan, unvested restricted stock and restricted stock units. The dilutive effect ofpotentially dilutive securities is reflected in diluted earnings (losses) per share by application of the treasury stock method.Income TaxesWe record income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expectedfuture tax consequences of events that have been recognized in our financial statements or tax returns. In estimating future tax consequences, generally allexpected future events other than enactments or changes in the tax law or rates are considered. Valuation allowances are provided when necessary to reducedeferred tax assets to the amount expected to be realized.We apply authoritative guidance for the accounting for uncertainty in income taxes. The guidance requires that tax effects of a position be recognizedonly if it is “more likely than not” to be sustained based solely on its technical merits as of the reporting date. Upon estimating our tax positions and taxbenefits, we consider and evaluate numerous factors, which may require periodic adjustments and which may not reflect the final tax liabilities. We adjust ourfinancial statements to reflect only those tax positions that are more likely than not to be sustained under examination.57 As part of the process of preparing consolidated financial statements, we are required to estimate our taxes in each of the jurisdictions in which weoperate. We estimate actual current tax exposure together with assessing temporary differences resulting from differing treatment of items, such as accrualsand allowances not currently deductible for tax purposes. These differences result in deferred tax assets, which are included in the consolidated balancesheets. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in the consolidated statementsof operations become deductible expenses under applicable income tax laws, or loss or credit carryforwards are utilized.In assessing whether deferred tax assets may be realized, we consider whether it is more likely than not that some portion or all of deferred tax assetswill be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income.We make estimates and judgments about our future taxable income based on assumptions that are consistent with our plans and estimates. Should theactual amounts differ from estimates, the amount of valuation allowance could be materially impacted. Any adjustment to the deferred tax asset valuationallowance would be recorded in the consolidated income statement for the periods in which the adjustment is determined to be required. ITEM 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKWe had cash, cash equivalents and marketable securities totaling $358.9 million and $434.6 million at January 31, 2019 and 2018, respectively. Ourcash is deposited in checking accounts with reputable financial institutions. The cash equivalents and marketable securities consist primarily of investmentsin debt securities. Our cash is held for working capital purposes. We do not enter into investments for trading or speculative purposes.Interest Rate Fluctuation RiskThe primary objectives of our investment activities are to preserve principal, provide liquidity and maximize income without significantly increasingrisk. Some of the securities we invest in are subject to market risk. This means that a change in prevailing interest rates may cause the principal amount of theinvestment to fluctuate. To minimize this risk, we maintain our portfolio of short-term investments in a variety of debt securities with high liquidity. We donot enter into investments for trading or speculative purposes. A 10% change in interest rates will not have a material impact on our future interest income orinvestment fair value. The risk associated with fluctuating interest rates is limited to our investment portfolio.Foreign Currency RiskTo date, all of our product sales and inventory purchases have been denominated in U.S. dollars. We therefore have not had any foreign currency riskassociated with these two activities. The functional currency of all of our entities is the U.S. dollar. Our operations outside of the United States incuroperating expenses and hold assets and liabilities denominated in foreign currencies, principally the New Taiwan Dollar and the Chinese Yuan Renminbi.Our results of operations and cash flows are subject to fluctuations due to changes in foreign currency exchange rates, particularly the exchange rates betweenthe Chinese Yuan Renminbi and the U.S. dollar and between the New Taiwan Dollar and the U.S. dollar. As we grow our operations, our exposure to foreigncurrency risk could become more significant. To date, we have not entered into any foreign currency exchange contracts and currently do not expect to enterinto foreign currency exchange contracts for trading or speculative purposes. 58 ITEM 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFinancial StatementsThe financial statements required by this Item are set forth as a separate section of this Annual Report on Form 10-K. See Item 15 for a listing offinancial statements provided in the section titled “Financial Statements.”Supplementary Data (Unaudited)The following table sets forth unaudited supplementary quarterly financial data for the two year period ended January 31, 2019. In management’sopinion, the unaudited data has been prepared on the same basis as the audited information and includes all adjustments necessary for a fair presentation ofthe data for the periods presented. For the Three Months Ended Jan. 31, Oct. 31, Jul. 31, Apr. 30, Jan. 31, Oct. 31, Jul. 31, Apr. 30, 2019 2018 2018 2018 2018 2017 2017 2017 (in thousands, except per share data) Revenue $51,070 $57,286 $62,474 $56,938 $70,575 $89,062 $71,630 $64,135 Cost of revenue 20,416 22,701 24,461 22,046 25,224 32,448 26,825 23,172 Gross profit 30,654 34,585 38,013 34,892 45,351 56,614 44,805 40,963 Operating expenses: Research and development 32,638 31,653 32,129 31,664 31,574 29,796 27,538 26,602 Selling, general and administrative 12,382 12,354 12,566 13,178 12,386 11,700 11,962 11,744 Total operating expenses 45,020 44,007 44,695 44,842 43,960 41,496 39,500 38,346 Income (loss) from operations (14,366) (9,422) (6,682) (9,950) 1,391 15,118 5,305 2,617 Other income, net 3,351 993 732 792 602 319 224 153 Income (loss) before income taxes (11,015) (8,429) (5,950) (9,158) 1,993 15,437 5,529 2,770 Provision (benefit) for income taxes (6,472) 592 927 848 732 3,713 2,226 206 Net income (loss) $(4,543) $(9,021) $(6,877) $(10,006) $1,261 $11,724 $3,303 $2,564 Net income (loss) per share attributable to ordinary shareholders: Basic $(0.14) $(0.28) $(0.21) $(0.30) $0.04 $0.35 $0.10 $0.08 Diluted $(0.14) $(0.28) $(0.21) $(0.30) $0.04 $0.34 $0.10 $0.07 Net income (loss) per ordinary share for the year is computed independently and may not equal the sum of the quarterly net income (loss) per ordinaryshare.Effective February 1, 2018, we adopted Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”)using a modified retrospective method with the cumulative effect recognized in the beginning retained earnings. The quarterly financial data for the periodended January 31, 2019 were reported under Topic 606, whereas the quarterly financial data for the period ended January 31, 2018 were reported under Topic605. See Note 2, "Revenue Recognition" of the Notes to Consolidated Financial Statements included in this report for more details.Our quarterly revenues and operating results are difficult to forecast. Therefore, we believe that period-to-period comparisons of our operating resultswill not necessarily be meaningful, and should not be relied upon as an indication of future performance. Also, operating results may fall below ourexpectations and the expectations of analysts or investors in one or more future quarters. If this were to occur, the market price of our ordinary shares wouldlikely decline. For further information regarding the quarterly fluctuation of our revenues and operating results, see Item 1A, “Risk Factors—Fluctuations inour operating results on a quarterly and annual basis could cause the market price of our ordinary shares to decline”. 59 ITEM 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENot applicable.ITEM 9A.CONTROLS AND PROCEDURESEvaluation of Disclosure Controls and ProceduresOur management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosurecontrols and procedures as of the end of the period covered by this Annual Report on Form 10-K. The term “disclosure controls and procedures” (as definedin Rules 13a- 15(e) and 15d- 15(e)) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that informationrequired to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, withinthe time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed toensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated andcommunicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisionsregarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide onlyreasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possiblecontrols and procedures. Based upon such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of January 31, 2019, our disclosurecontrols and procedures were effective at the reasonable assurance level.Management’s Report on Internal Control over Financial ReportingManagement of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules13a-15(f) and 15(d)-15(f) under the Exchange Act. The Company’s internal control over financial reporting is designed to provide reasonable assuranceregarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally acceptedaccounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections ofany evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that thedegree of compliance with the policies or procedures may deteriorate.Management has evaluated the effectiveness of our internal control over financial reporting based on the framework in Internal Control-IntegratedFramework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this evaluation, managementhas concluded that our internal control over financial reporting was effective as of January 31, 2019.The effectiveness of our internal control over financial reporting as of January 31, 2019 has been audited by PricewaterhouseCoopers LLP, anindependent registered public accounting firm, as stated in their report, which appears herein. Changes in Internal Control over Financial ReportingThere were no changes in our internal control over financial reporting during the Company’s fiscal quarter ended January 31, 2019 that havematerially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.Inherent Limitations of Disclosure Controls and Internal Control over Financial ReportingBecause of their inherent limitations, our disclosure controls and procedures and our internal control over financial reporting may not prevent materialerrors or fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of thecontrol system are met. The effectiveness of our disclosure controls and procedures and our internal control over financial reporting is subject to risks,including that the controls may become inadequate because of changes in conditions or that the degree of compliance with our policies or procedures maydeteriorate.ITEM 9B.OTHER INFORMATIONNot applicable. 60 PART IIIITEM 10.DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCEThe information responsive to this item is incorporated herein by reference to our Proxy Statement for our 2019 annual meeting of shareholders to befiled with the Securities and Exchange Commission pursuant to Regulation 14A not later than 120 days after the end of the fiscal year covered by thisAnnual Report on Form 10-K.We have a Code of Business Conduct and Ethics for all of our directors, officers and employees.

We also have audited theCompany's internal control over financial reporting as of January 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as ofJanuary 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended January 31, 2019 in conformitywith accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects,effective internal control over financial reporting as of January 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013)issued by the COSO. Change in Accounting Principle As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for revenue from contracts withcustomers in fiscal year 2019. Basis for Opinions The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, andfor its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over FinancialReporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company'sinternal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting OversightBoard (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and theapplicable 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 reasonableassurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internalcontrol over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financialstatements, 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 usedand significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internalcontrol over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weaknessexists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performingsuch other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. 63 Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reportingand the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal controlover financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairlyreflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permitpreparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are beingmade only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention ortimely 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 ofeffectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliancewith the policies or procedures may deteriorate. /s/ PricewaterhouseCoopers LLPSan Jose, CaliforniaMarch 29, 2019 We have served as the Company’s auditor since 2008. 64 AMBARELLA, INC.CONSOLIDATED BALANCE SHEETS(in thousands, except share and per share data) January 31, January 31, 2019 2018 ASSETS Current assets: Cash and cash equivalents $194,047 $346,672 Marketable debt securities 164,861 87,919 Accounts receivable, net 26,212 31,294 Inventories 18,252 23,383 Restricted cash 11 9 Prepaid expenses and other current assets 6,206 4,006 Total current assets 409,589 493,283 Property and equipment, net 6,728 6,449 Deferred tax assets, non-current 10,587 3,642 Intangible assets, net 10,936 14,417 Goodwill 26,601 26,601 Other non-current assets 2,412 2,257 Total assets $466,853 $546,649 LIABILITIES AND SHAREHOLDERS' EQUITY Current liabilities: Accounts payable 12,801 19,815 Accrued and other current liabilities 24,700 32,178 Income taxes payable 993 936 Deferred revenue, current 529 307 Total current liabilities 39,023 53,236 Other long-term liabilities 8,341 11,226 Total liabilities 47,364 64,462 Commitments and contingencies (Note 14) Shareholders' equity: Preference shares, $0.00045 par value per share, 20,000,000 shares authorized and no shares issued and outstanding at January 31, 2019 and January 31, 2018, respectively — — Ordinary shares, $0.00045 par value per share, 200,000,000 shares authorized at January 31, 2019 and January 31, 2018, respectively; 32,303,540 shares issued and outstanding at January 31, 2019; 33,489,614 shares issued and outstanding at January 31, 2018 15 15 Additional paid-in capital 188,516 221,186 Accumulated other comprehensive income (loss) 97 (279)Retained earnings 230,861 261,265 Total shareholders’ equity 419,489 482,187 Total liabilities and shareholders' equity $466,853 $546,649 See accompanying notes to consolidated financial statements. 65 AMBARELLA, INC.CONSOLIDATED STATEMENTS OF OPERATIONS(in thousands, except share and per share data) Year Ended January 31, 2019 2018 2017 Revenue $227,768 $295,402 $310,297 Cost of revenue 89,624 107,669 105,283 Gross profit 138,144 187,733 205,014 Operating expenses: Research and development 128,084 115,510 101,205 Selling, general and administrative 50,480 47,792 43,446 Total operating expenses 178,564 163,302 144,651 Income (loss) from operations (40,420) 24,431 60,363 Other income, net 5,868 1,298 518 Income (loss) before income taxes (34,552) 25,729 60,881 Provision (benefit) for income taxes (4,105) 6,877 3,071 Net income (loss) $(30,447) $18,852 $57,810 Net income (loss) per share attributable to ordinary shareholders: Basic $(0.93) $0.57 $1.77 Diluted $(0.93) $0.55 $1.68 Weighted-average shares used to compute net income (loss) per share attributable to ordinary shareholders: Basic 32,713,606 33,224,803 32,671,221 Diluted 32,713,606 34,583,150 34,327,724 See accompanying notes to consolidated financial statements. 66 AMBARELLA, INC.CONSOLIDATED STATEMENTS OF COMPREHENSIVE INCOME (LOSS)(in thousands) Year Ended January 31, 2019 2018 2017 Net income (loss) $(30,447) $18,852 $57,810 Other comprehensive income (loss), net of tax: Unrealized gains (losses) on investments 376 (209) (63)Other comprehensive income (loss), net of tax 376 (209) (63)Comprehensive income (loss) $(30,071) $18,643 $57,747 See accompanying notes to consolidated financial statements. 67 AMBARELLA, INC.CONSOLIDATED STATEMENTS OF SHAREHOLDERS’ EQUITY(in thousands, except share data) Accumulated Outstanding Additional Other Ordinary Shares Paid-in Comprehensive Retained Shares Amount Capital Income (Loss) Earnings Total Balance--January 31, 2016 32,333,359 $15 $176,306 $(7) $173,142 $349,456 Cumulative effect of change in accounting principle — — 227 — 11,461 11,688 Exercise of stock options 235,923 — 3,230 — — 3,230 Restricted stock awards granted 184,155 — — — — — Vesting of restricted stock units 894,710 — — — — — Employee stock purchase plan 125,974 — 4,034 — — 4,034 Stock repurchase (405,089) — (20,183) — — (20,183)Stock-based compensation expense related to stock awardsgranted to employees and consultants — — 48,832 — — 48,832 Excess income tax benefit associated with stock-basedcompensation — — (170) — — (170)Net unrealized gains (losses) on investments -

Organization and Summary of Significant Accounting PoliciesOrganizationAmbarella, Inc. (the “Company”) was incorporated in the Cayman Islands on January 15, 2004. The Company is a leading developer of low-power,high-definition (HD) and Ultra HD video compression and image processing solutions, and computer vision solutions. The Company combines its processordesign capabilities with its expertise in video and image processing, algorithms and software to provide a technology platform that is designed to be easilyscalable across multiple applications and enable rapid and efficient product development. The Company’s system-on-a-chip, or SoC, designs fully integratedhigh-definition video processing, image processing, analysis, audio processing and system functions onto a single chip, delivering exceptional video andimage quality, differentiated functionality and low power consumption. Currently the Company is combining advanced computer vision technology with itsstate-of-the-art video to enable the next generation of intelligent cameras, advanced driver assistance systems (ADAS) and autonomous vehicles.The Company sells its solutions to leading original design manufacturers, or ODMs, and original equipment manufacturers, or OEMs, globally. Basis of ConsolidationThe Company’s fiscal year ends on January 31. The consolidated financial statements of the Company and its subsidiaries have been prepared inconformity with accounting principles generally accepted in the United States (“U.S. GAAP”). All intercompany transactions and balances have beeneliminated in consolidation.Use of EstimatesThe preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions thataffect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reportedamounts of revenue and expense during the reported periods. Actual results could differ from those estimates.On an ongoing basis, management evaluates its estimates and assumptions, including those related to (i) the collectability of accounts receivable;(ii) write down of excess and obsolete inventories; (iii) intangible assets and goodwill; (iv) the estimated useful lives of long-lived assets; (v) impairment oflong-lived assets and financial instruments; (vi) warranty obligations; (vii) the valuation of stock-based compensation awards and financial instruments;(viii) the probability of performance objectives achievement; (ix) the realization of tax assets and estimates of tax liabilities, including reserves for uncertaintax positions; and (x) the recognition and disclosure of contingent liabilities. These estimates and assumptions are based on historical experience and onvarious other factors which the Company believes to be reasonable under the circumstances. The Company may engage third-party valuation specialists toassist with estimates related to the valuation of financial instruments, assets and stock awards associated with various contractual arrangements. Suchestimates often require the selection of appropriate valuation methodologies and significant judgment. Actual results could differ from these estimates underdifferent assumptions or circumstances and such differences could be material.Concentration of RiskThe Company’s products are manufactured, assembled and tested by third-party contractors located primarily in Asia. The Company does not havelong-term agreements with these contractors. A significant disruption in the operations of one or more of these contractors would impact the production of theCompany’s products which could have a material adverse effect on its business, financial condition and results of operations.A substantial portion of the Company’s revenue is derived from sales through one of its distributors, Wintech Microelectronics Co., Ltd., or Wintech,which serves as its non-exclusive sales representative in Asia other than Japan, and directly to one ODM customer, Chicony Electronics Co., Ltd., or Chicony.Termination of the relationships with these customers could result in a temporary or permanent loss of revenue. Furthermore, any credit issues from thesecustomers could impair their abilities to make timely payment to the Company. See Note 15 for additional information regarding revenue and creditconcentration with these customers.70 Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, marketablesecurities and accounts receivable. The Company maintains its cash primarily in checking accounts with reputable financial institutions. Cash deposits heldwith these financial institutions may exceed the amount of insurance provided on such deposits. The Company has not experienced any losses on deposits ofits cash. In order to limit the exposure of each investment, the cash equivalents and marketable securities consist primarily of money market funds, certificatesof deposit, asset-backed securities, commercial paper, U.S. government securities and debt securities of corporations which management assesses to be highlyliquid. The Company does not hold or issue financial instruments for trading purposes.The Company performs ongoing credit evaluation of its customers and adjusts credit limits based upon payment history and customers’ creditworthiness. The Company regularly monitors collections and payments from its customers.Foreign Currency TransactionsThe U.S. dollar is the functional currency for the Company and its subsidiaries. Monetary assets and liabilities denominated in non-U.S. currencies arere-measured to U.S. dollars using current exchange rates in effect at the balance sheet date. Nonmonetary assets and liabilities are re-measured to U.S. dollarsusing historical exchange rates. Monetary and other accounts are re-measured to U.S. dollars using average exchange rates in effect during each period. Gainsor losses from foreign currency re-measurement are included in other income, net in the consolidated statements of operations, and, to date, have not beenmaterial.Fair Value of Financial InstrumentsFair value accounting is applied to all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed in thefinancial statements on a recurring basis. The carrying amounts reflected in the consolidated balance sheets for cash equivalents, accounts receivable,accounts payable, accrued liabilities and other current liabilities, approximate fair value due to the short-term nature.Cash Equivalents and Marketable Debt SecuritiesThe Company considers all highly liquid debt security investments with original maturities of less than three months at the time of purchase to becash equivalents. Debt security investments that are highly liquid with original maturities at the time of purchase greater than three months are consideredmarketable debt securities.The Company classifies these investments as “available-for-sale” securities carried at fair value, based on quoted market prices of similar assets, withthe unrealized gains or losses reported, net of tax, as a separate component of shareholders’ equity and included in accumulated other comprehensive income(loss) in the consolidated balance sheets. The amortization of premiums and accretion of discounts and the realized gains and losses are both recorded inother income, net, in the consolidated statements of operations. The Company reviews its investments for possible other-than-temporary impairments on aregular basis. If any loss on investment is believed to be other-than-temporary, a charge will be recorded and a new cost basis in the investment will beestablished. In evaluating whether a loss on a security is other-than-temporary, the Company considers the following factors: (i) general market conditions,(ii) the duration and extent to which the fair value is less than cost and (iii) the Company’s intent and ability to hold the investment.For securities in an unrealized loss position which is deemed to be other-than-temporary, the difference between the security’s then-current amortizedcost basis and fair value is separated into (i) the amount of the impairment related to the credit loss (i.e., the credit loss component) and (ii) the amount of theimpairment related to all other factors (i.e., the non-credit loss component). The credit loss component is recognized in earnings. The non-credit losscomponent is recognized in accumulated other comprehensive loss. Due to the relative short term nature of the investments, there have been no other-than-temporary impairments recorded to date.71 Restricted CashAmounts included in restricted cash represent those required to be set aside to secure certain transactions in a foreign entity. As of January 31, 2019and 2018, the restricted cash was immaterial, respectively. The following table presents cash, cash equivalents and restricted cash reported on theconsolidated balance sheets, and the sums are presented on the consolidated statements of cash flows: As of January 31, 2019 2018 2017 (in thousands) Cash and cash equivalents $194,047 $346,672 $322,872 Restricted cash 11 9 8 Total as presented in the consolidated statements of cash flows $194,058 $346,681 $322,880 Trade Accounts Receivable and Allowances for Doubtful AccountsTrade accounts receivable are recorded at the invoiced amount and do not include finance charges. The Company performs ongoing credit evaluationof its customers and generally requires no collateral. The Company assesses the need for allowances for doubtful accounts for estimated losses resulting fromthe inability of its customers to make required payments by considering factors such as historical collection experience, credit quality, aging of the accountsreceivable balances and current economic conditions that may affect a customer’s ability to pay. There were no material write-offs of accounts receivable forthe fiscal years ended January 31, 2019, 2018 and 2017, respectively. There was no material allowance for doubtful accounts recorded as of January 31, 2019and 2018, respectively.InventoriesThe Company records inventories at the lower of cost or net realizable value. The cost includes materials and other production costs and is computedusing standard cost on a first-in, first-out basis. Inventory reserves are recorded for estimated obsolescence or unmarketable inventories based on forecast offuture demand and market conditions. Any adjustments to reduce the cost of inventories to their net realizable value are recognized in earnings in the currentperiod. Once inventory is written down, a new accounting cost basis is established and, accordingly, any associated reserve is not released until the inventoryis sold or scrapped. There were no material inventory losses recognized for the fiscal years ended January 31, 2019, 2018 and 2017, respectively.Property and EquipmentProperty and equipment are stated at cost and depreciated using the straight-line method over the estimated useful life for computer equipment,computer software, machinery, equipment and furniture and fixture. Leasehold improvements are amortized over the shorter of the lease term or theirestimated useful lives. Repairs and maintenance are charged to expense as incurred.Noncancelable Software LicenseThe Company accounts for a noncancelable on premise internal-use software license as the acquisition of an intangible asset and the incurrence of aliability to the extent that all or a portion of the software licensing fees are not paid on or before the license acquisition date. The intangible asset and relatedliability are recorded at net present value and interest expense is recorded over the payment term.Goodwill and In-Process Research and DevelopmentThe Company does not amortize goodwill. Acquired in-process research and development, or IPR&D, is capitalized at fair value as an intangible assetand amortization commences upon completion of the underlying projects. When a project underlying reported IPR&D is completed, the correspondingamount of IPR&D is reclassified as an amortizable purchased intangible asset and is amortized over its estimated useful life. As of January 31, 2019, there wasno IPR&D amortized.72 Impairment of Long-Lived Assets Including Goodwill and Other Acquired Intangible AssetsThe Company reviews property and equipment and intangible assets, excluding goodwill, for impairment at least annually in the fourth fiscal quarteror whenever events or changes in circumstances indicate that the carrying amount of an asset, or asset group, may not be recoverable. Determination ofrecoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset, or asset group to estimated undiscounted futurecash flows expected to be generated by the asset, or asset group. If the carrying amount of an asset or asset group exceeds its estimated undiscounted futurecash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset or asset group exceeds the estimated fair value ofthe asset or asset group. Fair value is determined based on the estimated discounted future cash flows expected to be generated by the asset or asset group.Events or changes in circumstances that may indicate that an asset is impaired include significant decreases in the market value of an asset, significantunderperformance relative to expected historical or projected future results of operations, a change in the extent or manner in which an asset is utilized,significant declines in the estimated fair value of the overall Company for a sustained period, shifts in technology, loss of key management or personnel,changes in the Company’s operating model or strategy and competitive forces. There has been no occurrence of events to date that would trigger animpairment analysis. As such, no impairment charge has been recognized as of January 31, 2019.The Company tests the goodwill for impairment at least annually in the fourth fiscal quarter, or sooner whenever events or changes in circumstancesindicate that the asset may be impaired. The Company has a single reporting unit for goodwill impairment test purposes based on its business and reportingstructure. No goodwill impairment has been identified to date.Equity InvestmentThe Company accounts for its investment in a privately held company as an equity investment and reports the investment in other non-current assetsin the consolidated balance sheets. The Company chooses to measure this equity investment that does not have readily determinable fair value at cost minusany recorded impairments, adjusted for observable price changes in transactions for an identical or similar investment of the same issuer. Upon determiningthat an impairment or observable price change exists, the Company records any adjustment to the fair value of the investment through net income. To date,there have been no identified events or changes in circumstances that may have a significant effect on the fair value of this investment and the Company hasnot recognized any impairment losses related to this investment nor have there been any observable price changes.Revenue RecognitionEffective February 1, 2018, the Company adopted Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers(“ASC 606”), using the modified retrospective method applied to those contracts that were not completed as of February 1, 2018. Results for reportingperiods beginning after February 1, 2018 are presented under ASC 606. Prior period amounts are not adjusted and continue to be reported in accordance withthe Company’s historic accounting under ASC Topic 605, Revenue Recognition (“ASC 605”). The most significant impacts of this new guidance for theCompany relate to the determination of transaction price and the timing of revenue recognition for transactions with distributors. As a result, the Companynow recognizes product revenue upon shipment and transfer of control to distributors (known as “sell-in” revenue recognition) rather than shipment to theend customers (known as “sell-through” revenue recognition) based on its estimate of the consideration it expects to receive. Revenue recognition isevaluated through the following five steps: (i) identification of the contract, or contracts, with a customer; (ii) identification of the performance obligations inthe contract; (iii) determination of the transaction price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v)recognition of revenue when or as a performance obligation is satisfied.The sale of semiconductor products accounts for the substantial majority of the Company’s consolidated revenue. Sales agreements with customers arerenewable periodically and contain terms and conditions with respect to payment, delivery, warranty, supply and other rights. The Company considers anaccepted customer purchase order, governed by sales agreement, to be the contract with the customer. For each contract, the Company considers the promiseto transfer tangible products to be the identified performance obligation. Product sales contracts may include volume-based tiered pricing or rebates that arefulfilled in cash or product. In determining the transaction price, the Company accounts for the right of returns, cash rebates, commissions and other pricingadjustments as variable consideration and estimates these amounts based on the expected amount to be provided to customers and reduces the revenuerecognized. The Company estimates sales returns and rebates based on the Company’s historical patterns of return and pricing credits. As the Company’sstandard payment terms are 30 days to 60 days, the contracts have no financing component. Under ASC 606, the Company estimates the total considerationto be received by using the expected value method for each contract, computes weighted average selling price for each unit shipped in cases where there is amaterial right due to the presence of volume-based tiered pricing, allocates the total consideration between the identified performance obligations, andrecognizes revenue when control of its goods and services is transferred to its customers. The Company considers product control to be transferred atshipment or delivery because the Company has a present right to payment at that time, the customer has legal title to the asset, the Company has transferredphysical possession of the asset, and the customer has significant risk and rewards of ownership of the asset.73 The Company also enters into fixed-price engineering service agreements with certain customers. These agreements may include multiple performanceobligations, such as software development services, licensing of intellectual property and post-contract customer support, or PCS. These multipleperformance obligations are highly interdependent, highly interrelated, are typically not sold separately and do not have standalone selling prices. They areall inputs to generate one combined output which is incorporating the Company’s SoC into the customer’s product. Accordingly, the Company determinesthat these inputs are not separately identifiable and shall be treated as a single performance obligation. Customers usually pay based on milestones achieved.Because payments received do not correspond directly with the value of the Company’s performance to date, for fixed-price engineering servicesarrangements, revenue is recognized using the time-based straight line method, which best depicts the Company’s performance toward complete satisfactionof the performance obligation based on the nature of such professional services. Revenues from engineering service agreements were not material for thefiscal years ended January 31, 2019, 2018 and 2017, respectively.Cost of RevenueCost of revenue includes cost of materials, cost associated with packaging and assembly, testing and shipping, cost of personnel, stock-basedcompensation, logistics and quality assurance, warranty cost, royalty expense, write-downs of inventories and allocation of overhead.Warranty CostsThe Company typically provides warranty on its products. The Company accrues for the estimated warranty costs at the time when revenue isrecognized. The warranty accruals are regularly monitored by management based upon historical experience and any specifically identified failures. Whilethe Company engages in extensive product quality assessment, actual product failure rates, material usage or service delivery costs could differ fromestimates and revisions to the estimated warranty liability would be required. There was no warranty accrual as of January 31, 2019. As of January 31, 2018,the warranty accruals recorded in the consolidated balance sheets were approximately $1.8 million.Research and DevelopmentResearch and development costs are expensed as incurred and consist primarily of personnel costs, product development costs, which includeengineering services, development software and hardware tools, license fees, costs of fabrication of masks for prototype products, other developmentmaterials costs, depreciation of equipment used in research and development and allocation of facility costs.Selling, General and AdministrativeSelling, general and administrative expenses consist of personnel costs, travel and trade show costs, legal expenses, other professional services andoccupancy costs. Advertising expenses were not material for the fiscal years ended January 31, 2019, 2018 and 2017, respectively.Operating LeasesThe Company recognizes rent expense on a straight-line basis over the term of the lease. The difference between rent expense and rent payment isrecorded as deferred rent and is included in accrued liabilities in the consolidated balance sheets.74 Stock-Based CompensationThe Company measures stock-based compensation for equity awards granted to employees and directors based on the estimated fair value on the grantdate, and recognizes that compensation as expense using the straight-line attribution method for service condition awards or using the graded-vestingattribution method for awards with performance conditions over the requisite service period, which is typically the vesting period of each award. TheCompany determines the fair value of restricted stock and restricted stock units with service or performance conditions based on the fair market value of itsordinary shares on the grant date. The Company uses the Black-Scholes option pricing model to determine the fair value of stock options. Determining thefair value of stock options on the grant date requires the input of various assumptions, including stock price of the underlying ordinary share, the exerciseprice of the stock option, expected volatility, expected term, risk-free interest rate and dividend rate. In prior fiscal years, the expected term was calculatedusing the simplified method, and the expected volatility was calculated based on the weighted average of historical volatilities of the Company’s stock priceand the share prices of similar companies that are publicly available for a period commensurate with the expected term. Starting from fiscal year 2019, theCompany calculates expected volatility based on its own historical stock price for a period commensurate with the expected term, which is computed basedon its own historical exercise behavior. The risk-free interest rate is derived from an average of the U.S. Treasury constant maturity rates for the respectiveperiods most closely commensurate with the expected term. The expected dividend yield is zero because the Company has not historically paid dividendsand has no present intention to pay dividends. The Company uses the Lattice pricing model and performs Monte Carlo Simulation to evaluate the fair valueof awards with market conditions, including assumptions of historical volatility and risk-free interest rate commensurate with the vesting term. Uponadoption of ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting in the firstquarter of fiscal year 2017, the Company elects to account for forfeitures as they occur.Income TaxesThe Company records income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for theexpected future tax consequences of events that have been recognized in its financial statements or tax returns. In estimating future tax consequences,generally all expected future events other than enactments or changes in the tax law or rates are considered. Valuation allowances are provided whennecessary to reduce deferred tax assets to the amount expected to be realized.The Company applies authoritative guidance for the accounting for uncertainty in income taxes. The guidance requires that tax effects of a positionbe recognized only if it is “more likely than not” to be sustained based solely on its technical merits as of the reporting date. Upon estimating its taxpositions and tax benefits, the Company considers and evaluates numerous factors, which may require periodic adjustments and which may not reflect thefinal tax liabilities. The Company adjusts its financial statements to reflect only those tax positions that are more likely than not to be sustained underexamination.As part of the process of preparing consolidated financial statements, the Company is required to estimate its taxes in each of the jurisdictions inwhich it operates. The Company estimates actual current tax exposure together with assessing temporary differences resulting from differing treatment ofitems, such as accruals and allowances not currently deductible for tax purposes. These differences result in deferred tax assets, which are included in theconsolidated balance sheets. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in theconsolidated statements of operations become deductible expenses under applicable income tax laws, or loss or credit carryforwards are utilized.In assessing whether deferred tax assets may be realized, the Company considers whether it is more likely than not that some portion or all of deferredtax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income.The Company makes estimates and judgments about its future taxable income based on assumptions that are consistent with its plans and estimates.Should the actual amounts differ from estimates, the amount of valuation allowance could be materially impacted. Any adjustment to the deferred tax assetvaluation allowance would be recorded in the consolidated income statement for the periods in which the adjustment is determined to be required.Net Income (Loss) Per Ordinary ShareBasic earnings (losses) per share is computed by dividing net income (loss) available to ordinary shareholders by the weighted-average number ofordinary shares outstanding during the period. Diluted earnings (losses) per share is computed by dividing net income (loss) available to ordinaryshareholders by the weighted-average number of ordinary shares outstanding during the period increased to include the number of additional ordinary sharesthat would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options,shares to be purchased under the Company’s employee stock purchase plan, unvested restricted stock and restricted stock units. The dilutive effect ofpotentially dilutive securities is reflected in diluted earnings (losses) per share by application of the treasury stock method.75 Comprehensive Income (Loss)Comprehensive income (loss) includes unrealized gains or losses from available-for-sale securities that are excluded from net income (loss).Recent Accounting PronouncementsIn February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, Leases (Topic 842). Under this new guidance, lessees arerequired to recognize leases as right-of-use assets and corresponding lease liabilities on the balance sheet, while recognizing expenses on the incomestatements in a manner similar to current guidance. This new guidance is effective for fiscal years beginning after December 15, 2018, including interimperiods within those fiscal years, with early adoption permitted. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvement,which provides the alternative transition method with a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoptionwithout adjustment of comparative period financial statements. The Company did not early adopt this new guidance and decided to adopt the new guidanceusing the alternative transition method effective in the first quarter of its fiscal year 2020. The Company is still in the finalization of the calculation andimplementation related to system solution, processes, practical expedients and policy elections offered by the standard. The Company is also evaluating itsinternal controls to meet the new standard’s requirements. Although the Company has not completed the implementation, it expects the net present value ofthe right-of-use assets and lease liabilities at the beginning of the first quarter of fiscal year 2020 to be within the range of $8.0 million to $10.0 million,primarily relating to its office facilities, and does not expect that the adoption of this new guidance will have a material impact to the Company’sconsolidated statements of operations and cash flows.In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326), to introduce a new impairment model for recognizingcredit losses on financial instruments based on an estimate of current expected credit losses (“ECL”). Under the new model, an entity is required to estimateECL on available-for-sale (AFS) debt securities only when the fair value is below the amortized cost of the asset and is no longer based on an impairmentbeing “other-than-temporary”. The new model also requires the impairment calculation on an individual security level and requires an entity use presentvalue of cash flows when estimating the ECL. The credit-related losses are required to be recognized through earnings and non-credit related losses arereported in other comprehensive income. The ASU will be effective for public entities in fiscal years beginning after December 15, 2019, including interimperiods within those fiscal years. The new guidance will require modified retrospective application to all outstanding instruments, with a cumulative effectadjustment recorded to opening retained earnings as of the beginning of the first period in which the guidance becomes effective. The Company does notbelieve the adoption of this new guidance will have a material impact on its consolidated financial statements.In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test of Goodwill Impairment,to eliminate the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record animpairment charge based on the excess of a reporting unit’s carrying amount over its fair value. This new guidance will be applied prospectivelyand is effective for annual and interim periods beginning after December 15, 2019. The Company does not believe the adoption of this new guidancewill have a material impact on its financial position, results of operations and disclosures.In March 2017, the FASB issued ASU 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): PremiumAmortization On Purchased Callable Debt Securities, to shorten the amortization period for the premium to the earliest call date instead of thecontractual life of the instrument. This new guidance will be effective for fiscal years, and interim periods within those fiscal years, beginning afterDecember 15, 2018. Entities will be required to apply the new guidance using the modified retrospective method with a cumulative-effectadjustment to retained earnings upon the adoption date. The Company does not believe the adoption of this new guidance will have a material impact onits financial position, results of operations and disclosures.In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification ofCertain Tax Effects from Accumulated Other Comprehensive Income, to permit entities to have the option to reclassify tax effects stranded inaccumulated other comprehensive income as a result of tax reform to retained earnings. The FASB also gives entities the option to apply theguidance retrospectively or in the period of adoption. The guidance is effective for fiscal years beginning after December 15, 2018 and interimperiods within those fiscal years. Early adoption in any period is permitted. The Company did not early adopt and believes that the adoption of thisnew guidance will not have an impact on its financial position and disclosures.76 In June 2018, the FASB issued ASU 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, to align the measurement and classification guidance for share-based payments to nonemployees with the guidancefor share-based payments to employees, with certain exceptions. This new guidance is effective for fiscal years beginning after December 15,2018 and interim periods within those fiscal years. Early adoption is permitted, including in an interim period, but not before an entity adopts thenew revenue guidance. The Company has early adopted this new guidance which did not have significant impact on its financial position, results ofoperations and disclosures.In August 2018, the FASB issued 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the DisclosureRequirements for Fair Value Measurement. Under this new guidance, entities will no longer be required to disclose the amount of and reasons fortransfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to developsignificant unobservable inputs for Level 3 fair value measurements. The guidance is effective for fiscal years beginning after December 15, 2019and for the interim periods within those fiscal years. Early adoption is permitted. The Company does not believe the adoption of this new guidance willhave a material impact on its financial position, results of operations and disclosures.In August 2018, the FASB issued 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’sAccounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. Under this new guidance, entitiesare required to capitalize implementation costs related to a hosting arrangement that is a service contract and amortize the costs over the term ofthe hosting arrangement, beginning when the module or component of the hosting arrangement is ready for its intended use. The guidance iseffective for fiscal years beginning after December 15, 2019 and for the interim periods within those fiscal years. Early adoption is permitted. TheCompany does not believe the adoption of this new guidance will have a material impact on its financial position, results of operations and disclosures. 2. Revenue RecognitionEffective February 1, 2018, the Company adopted ASC 606 using the modified retrospective method applied to those contracts which were notcompleted as of February 1, 2018. Results for reporting periods beginning after February 1, 2018 are presented under ASC 606. Prior period amounts are notadjusted and continue to be reported in accordance with the Company’s historic accounting under ASC 605. The Company recognizes revenue when controlof its goods and services is transferred to its customers. The Company considers product control to be transferred at a point in time upon shipment or deliverybecause the Company has a present right to payment at that time, the customer has legal title to the asset, the Company has transferred physical possession ofthe asset, and the customer has significant risk and rewards of ownership of the asset. The majority of the Company’s product revenue is derived from salesthrough its distributors. As a result, sales of products are recognized upon shipment and transfer of control to distributors (known as “sell-in” revenuerecognition) rather than shipment to the end customers (known as “sell-through” revenue recognition).The cumulative effects of adjustments on the consolidated balance sheet on February 1, 2018 upon the adoption of ASC 606 were as follows: Balance as of Opening Balance as of January 31, 2018 Adjustment February 1, 2018 (in thousands) Deferred revenue, current $307 $(43) $264 Retained earnings $261,265 $43 $261,308The following table summarizes the impacts of adopting the new revenue standard on our consolidated balance sheets, statements of operations andstatements of cash flows as of and for the fiscal year ended January 31, 2019: 77 January 31, 2019 As Reported Impact of Adoption Amounts under ASC605 (in thousands) Consolidated Balance Sheets Assets: Deferred tax assets, non-current $10,587 34 $10,621 Liabilities: Accounts payable 12,801 (150) 12,651 Accrued and other current liabilities 24,700 (32) 24,668 Income taxes payable 993 1 994 Deferred revenue, current 529 4,957 5,486 Other long-term liabilities 8,341 3 8,344 Equity: Retained earnings $230,861 (4,745) $226,116 Twelve Months Ended January 31, 2019 As Reported Impact of Adoption Amounts under ASC605 (in thousands, except per share data) Consolidated Statements of Operations Revenue $227,768 $(7,317) $220,451 Cost of revenue 89,624 (2,584) 87,040 Gross profit 138,144 (4,733) 133,411 Loss from operations (40,420) (4,733) (45,153)Loss before income taxes (34,552) (4,733) (39,285)Provision (benefit) for income taxes (4,105) (31) (4,136)Net loss $(30,447) $(4,702) $(35,149) Net loss per share: Basic $(0.93) $(0.14) $(1.07)Diluted $(0.93) $(0.14) $(1.07)The impact of adoption on the comprehensive loss is the same as the impact on net loss. Twelve Months Ended January 31, 2019 As Reported Impact of Adoption Amounts under ASC605 (in thousands) Consolidated Statements of Cash Flows Cash flow from operating activities: Net loss $(30,447) $(4,702) $(35,149)Deferred income taxes $(6,945) (34) $(6,979)Accounts payable (7,014) (150) (7,164)Accrued liabilities (8,302) (32) (8,334)Income taxes payable 57 1 58 Deferred revenue 265 4,914 5,179 Other long-term liabilities $1,289 $3 $1,292The impacts of adoption of the new revenue standard were primarily attributable to distributor revenues recognized using the sell-through methodunder ASC 605, while such revenues are recognized using the sell-in method under ASC 606. 78 Practical Expedients •The Company elects not to disclose the value of unsatisfied or partially unsatisfied performance obligations due to original expected contractduration of one year or less. •For contracts that were modified before the adoption date, the Company elects to reflect the aggregate effect of all modifications that occur beforethe adoption date when identifying performance obligations, determining the transaction price, and allocating the transaction price to performanceobligations. •The Company also elects to exclude amounts collected from customers for all sales taxes from the transaction price.Contract AssetsTiming of revenue recognition may differ from the timing of invoicing to the Company's customers. The Company records contract assets whenrevenue is recognized prior to invoicing. The contract assets are primarily related to the Company’s engineering service agreements and rights toconsideration for performance obligations delivered but not billed at the reporting date. The contract assets are reclassified to receivables when the billingoccurs. As of February 1, 2018, the contract assets were not material. All of the contract assets were either reclassified to accounts receivables or recognized ascash receipts as of January 31, 2019. Contract Liabilities (Deferred Revenues)Contract liabilities are primarily related to the portion of transaction price that exceeds the weighted average selling price for products sold to dateunder tiered-pricing contracts which contain material rights. These contract liabilities are expected to be recognized over the course of the contract whenproducts are delivered for future pricing below the weighted average selling price of the contract. The timing of recognition of these contract liabilities isdependent on the timing and size of future orders under the contract. For the twelve months ended January 31, 2019, the Company did not recognize anymaterial revenue adjustment related to performance obligations satisfied in prior periods released from these contract liabilities.Contract liabilities are also recorded when cash payments are received in advance of performance for engineering service agreements. The contractliabilities related to these agreements are expected to be recognized when the performance is delivered. For the twelve months ended January 31, 2019, theCompany did not recognize any material revenue released from these contract liabilities as a result of performance obligations satisfied in the current period.As of January 31, 2019 and February 1, 2018, the contract liabilities were not material. Additionally, the transaction price allocated to unsatisfied, orpartially unsatisfied, purchase orders for contracts that are greater than a year was not material as of January 31, 2019 and February 1, 2018. 79 3. Financial Instruments and Fair ValueThe Company invests a portion of its cash in debt securities that are denominated in United States dollars. In fiscal year 2019, the Company added anadditional $100.0 million of capital in debt security investments. The investment portfolio consists of money market funds, certificates of deposit, asset-backed securities, commercial paper, U.S. government securities and debt securities of corporations. All of the investments are classified as available-for-salesecurities and reported at fair value in the consolidated balance sheets as follows: As of January 31, 2019 Amortized Cost Unrealized Gains Unrealized Losses Fair Value (in thousands) Money market funds $8,914 $— $— $8,914 Certificates of Deposit 7,012 — — 7,012 Commercial paper 68,233 — — 68,233 Corporate bonds 87,250 170 (60) 87,360 Asset-backed securities 11,607 3 (6) 11,604 U.S. government securities 21,993 3 (13) 21,983 Total cash equivalents and marketable debt securities $205,009 $176 $(79) $205,106 As of January 31, 2018 Amortized Cost Unrealized Gains Unrealized Losses Fair Value (in thousands) Money market funds $13,788 $— $— $13,788 Commercial paper 5,480 — — 5,480 Corporate bonds 53,175 — (196) 52,979 Asset-backed securities 11,048 — (44) 11,004 U.S. government securities 18,495 — (39) 18,456 Total cash equivalents and marketable debt securities $101,986 $— $(279) $101,707 As of January 31,2019 January 31,2018 (in thousands) Included in cash equivalents $40,245 $13,788 Included in marketable debt securities 164,861 87,919 Total cash equivalents and marketable debt securities $205,106 $101,707 The contractual maturities of the investments at January 31, 2019 and 2018 were as follows: As of January 31,2019 January 31,2018 (in thousands) Due within one year $151,991 $63,476 Due within one to three years 53,115 38,231 Total cash equivalents and marketable debt securities $205,106 $101,707 The unrealized losses on the available-for-sale securities were caused by fluctuations in market value and interest rates as a result of the economicenvironment. As the decline in market value was attributable to changes in market conditions and not credit quality, and because the Company neitherintended to sell nor was it more likely than not that it will be required to sell these investments prior to a recovery of par value, the Company did not considerthese investments to be other-than temporarily impaired as of January 31, 2019 and 2018, respectively.80 The following fair value hierarchy is applied for disclosure of the inputs used to measure fair value. This hierarchy prioritizes the inputs into threebroad levels as follows:Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.Level 2—Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the assets or liabilities, eitherdirectly or indirectly through market corroboration, for substantially the full term of the financial instruments.Level 3—Unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value. The inputs requiresignificant management judgment or estimation.The Company measures the fair value of money market funds and certificates of deposit using quoted prices in active markets for identical assets andclassifies them within Level 1. The fair value of the Company’s investments in other debt securities are obtained based on quoted prices for similar assets inactive markets and are classified within Level 2.The following tables present the fair value of the financial instruments measured on a recurring basis as of January 31, 2019 and 2018, respectively: As of January 31, 2019 Total Level 1 Level 2 Level 3 (in thousands) Money market funds $8,914 $8,914 $— $— Certificates of Deposit 7,012 7,012 Commercial paper 68,233 — 68,233 — Corporate bonds 87,360 — 87,360 — Asset-backed securities 11,604 — 11,604 — U.S. government securities 21,983 — 21,983 — Total cash equivalents and marketable debt securities $205,106 $15,926 $189,180 $— As of January 31, 2018 Total Level 1 Level 2 Level 3 (in thousands) Money market funds $13,788 $13,788 $— $— Commercial paper 5,480 — 5,480 — Corporate bonds 52,979 — 52,979 — Asset-backed securities 11,004 — 11,004 — U.S. government securities 18,456 — 18,456 — Total cash equivalents and marketable debt securities $101,707 $13,788 $87,919 $— 4. InventoriesInventories at January 31, 2019 and 2018 consisted of the following: As of January 31, 2019 2018 (in thousands) Work-in-progress $9,430 $12,073 Finished goods 8,822 11,310 Total $18,252 $23,383 81 5. Property and Equipment, netDepreciation expense was approximately $2.6 million, $1.8 million and $1.5 million for the fiscal years ended January 31, 2019, 2018 and 2017,respectively. Property and equipment at January 31, 2019 and 2018 consisted of the following: As of January 31, 2019 2018 (in thousands) Computer equipment and software $9,098 $8,611 Machinery and equipment 5,659 4,761 Furniture and fixtures 969 917 Leasehold improvements 2,331 2,092 Construction in progress 330 — 18,387 16,381 Less: accumulated depreciation and amortization (11,659) (9,932)Total property and equipment, net $6,728 $6,449 6. Intangible AssetsThe intangible assets primarily consist of $4.1 million of IPR&D from the acquisition of VisLab S.r.l., or VisLab, in June 2015 and $6.8 million ofnoncancelable software licenses, net of amortization expense. Acquired IPR&D is capitalized at fair value and the amortization commences upon completionof the underlying projects. When a project underlying reported IPR&D is completed, the corresponding amount of IPR&D is reclassified as an amortizablepurchased intangible asset and is amortized over its estimated useful life. As of January 31, 2019, there was no IPR&D amortized. The Company willdetermine the project incorporating the VisLab IPR&D to be completed when a related chip begins mass production to address the level 3 and aboveadvanced driving assistance systems markets.The Company enters into certain internal-use noncancelable software license agreements with third parties from time-to-time. The licenses have beencapitalized as intangible assets, and the corresponding future payments have been recorded as liabilities at net present value. As of January 31, 2019, $4.9million was recorded in accrued and other current liabilities and $0.3 million was recorded in other long-term liabilities in the consolidated balance sheets.The carrying amounts of intangible assets as of January 31, 2019 and 2018 were as follows: As of January 31, 2019 As of January 31, 2018 GrossCarryingAmount AccumulatedAmortization Net CarryingAmount GrossCarryingAmount AccumulatedAmortization Net CarryingAmount (in thousands) In-process research and development $4,100 $— $4,100 $4,100 $— $4,100 Internal-use software license 14,448 (7,612) 6,836 13,404 (3,087) 10,317 Total acquired intangible assets $18,548 $(7,612) $10,936 $17,504 $(3,087) $14,417The amortization expense related to these software licenses was approximately $4.7 million and $3.0 million for the fiscal years ended January 31,2019 and 2018, respectively, but was not material for the fiscal year ended January 31, 2017.

The primary jurisdiction where our foreignearnings are derived is the Cayman Islands, where the Company is domiciled. Under the current laws of the Cayman Islands, the Company is not subject totax on its income. For purposes of the reconciliation between the provision (benefit) for income taxes at the statutory rate and the effective tax rate, a notionalU.S. 21.0%, 33.8% and 34.0% rates are applied to pretax income (loss) as a result of the following for the periods indicated, respectively: Year Ended January 31, 2019 2018 2017 (in thousands) Provision at U.S. notional statutory rate $(7,256) $8,699 $20,700 U.S. state taxes 2 2 (216)Non-U.S. foreign tax differential 9,226 (6,424) (18,357)Stock-based compensation 4,715 4,645 1,605 U.S. R&D credit (2,770) (2,408) (2,226)Valuation allowance (7,990) (1) 1,901 Change in tax rate — 2,252 — Other (32) 112 (336)Provision (benefit) for income taxes $(4,105) $6,877 $3,07188 Income tax benefit for fiscal year 2019 was primarily due to the release of approximately $8.0 million of valuation allowance related to prior yearfederal research and development credit carryforwards, as well as the reduction in the U.S. federal statutory rate from 35% to 21%, partially offset by adecrease in the proportion of profits generated in lower tax jurisdictions and losses incurred in jurisdictions for which the Company was not able to recognizea related tax benefit. On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was enacted into law in the United States. The new tax legislation containsseveral provisions that will impact the Company, including the reduction of the corporate income tax rate from 35% to 21%, acceleration of business assetexpensing, and a reduction in the amount of executive pay that may qualify as a tax deduction, among others. The income tax benefit recorded for the fiscalyear ended January 31, 2019 includes the impact of the new tax legislation as currently interpreted by the Company. Due to the complexities of the new tax legislation, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 (“SAB118”) which allows for the recognition of provisional amounts during a measurement period. The measurement period begins in the reporting period thatincludes the Tax Act’s enactment date and ends when the additional information is obtained, prepared, or analyzed to complete the accounting requirementsunder ASC Topic 740. The measurement period should not extend beyond one year from the enactment date. The Company recorded provisional estimatesfor the fiscal year ended January 31, 2018 for the following: the revaluation of deferred tax assets and liabilities to reflect the 21% corporate tax rate, whetherto elect to expense or depreciate new capital equipment, and the U.S. state tax impact to the aforementioned items. The Company has completed its analysis of the impact of the Tax Act for the fiscal year ended January 31, 2018 and recorded adjustments to theprovisional amounts on its financial statements in the fiscal year ended January 31, 2019, which reduced the Company’s effective tax rate. The Companyrecorded an increase to deferred tax assets of approximately $83,000 and a decrease to long term tax liability of approximately $170,000, with acorresponding decrease to income tax expense of approximately $252,000 related to the reduction of the corporate tax rate. The income tax benefit wasprimarily the result of the clarifying guidance issued by the IRS in regards to the corporate alternative minimum tax rate for fiscal year taxpayers. Temporary differences that gave rise to significant portions of the Company’s deferred tax assets and liabilities at January 31, 2019 and 2018 wereas follows: As of January 31, 2019 2018 (in thousands) Deferred tax assets: Federal and state credits $19,426 $18,176 Expenses not currently deductible 575 1,213 Stock-based compensation 3,202 2,899 Foreign deferred 122 229 Gross deferred tax assets 23,325 22,517 Valuation allowance (12,526) (18,538)Total deferred tax assets $10,799 $3,979 Deferred tax liabilities Property and equipment (1,505) (1,655)Net deferred tax assets $9,294 $2,324 Tax valuation allowance for the periods indicated below were as follows: Deductions Additions Charged to Balance at Additional Charged to Expenses Balance at Beginning of Charged to Other or Other End of Period Expenses Account Accounts Period (in thousands) Tax Valuation Allowance Year ended January 31, 2019 $18,538 1,978 — (7,990) $12,526 Year ended January 31, 2018 $15,061 3,477 — — $18,538 Year ended January 31, 2017 $12,072 2,989 — — $15,061 89 The Company conducts its business in several countries and regions and is subject to taxation in those jurisdictions. The Company is incorporated inthe Cayman Islands with foreign subsidiaries in the U.S., China, Taiwan, Italy and other foreign countries and regions. As such, the Company’s worldwideoperating income is subject to varying tax rates and its effective tax rate is highly dependent upon the geographic distribution of its earnings or losses andthe tax laws and regulations in each geographical region. Consequently, the Company has experienced lower effective tax rates as a substantial amount of itsoperations are conducted in lower-tax jurisdictions. If the Company’s operational structure was to change in such a manner that would increase the amount ofoperating income subject to taxation in higher-tax jurisdictions, or if the Company was to commence operations in jurisdictions assessing relatively highertax rates, its effective tax rate could fluctuate significantly on a quarterly basis and/or be adversely affected. Dividend distributions received from theCompany’s U.S. subsidiary and certain other foreign subsidiaries may be subject to local country withholding taxes when, and if, distributed. Deferred taxliabilities have not been recorded on unremitted earnings of certain subsidiaries because management’s intent is to indefinitely reinvest any undistributedearnings in those subsidiaries. If dividend distributions from those subsidiaries were to occur, the liability as of January 31, 2019 would be $10.1 million.Cumulative undistributed earnings of foreign subsidiaries for which no deferred taxes have been provided approximated $67.2 million at January 31, 2019.As of January 31, 2019 and 2018, the Company had deferred tax assets (net of deferred tax liabilities) before valuation allowance, of $21.8 million and$20.8 million, respectively. The Company assesses whether a valuation allowance should be established against its deferred tax assets based on theconsideration of all available evidence, using a “more likely than not” standard. In the fourth quarter of fiscal year 2019, the Company determined that, basedon its cumulative profits before taxes and estimates of future forecasts of continued profitability in the United States, sufficient positive evidence existed toconclude that the valuation allowance on the U.S. federal research and development credit carryforwards was no longer needed. Accordingly, the Companyrealized approximately $8.0 million in deferred tax assets and a corresponding decrease in income tax expense related to the release of the valuationallowance for the U.S. federal research and development credit carryforwards.The Company also has Federal and California state research and development credit carryforwards of approximately $16.9 million and $20.0 million,respectively, at January 31, 2019. The Federal credits begin to expire in fiscal year 2033. The California credits can be carried forward indefinitely.The Company reports its U.S. state deferred tax assets and related valuation allowance, net of the U.S federal tax rate of 21%. As of January 31, 2019,the Company has recorded a valuation allowance of $12.5 million against all of its U.S. state deferred tax assets due to uncertainty regarding the futureutilization of these deferred tax assets.Utilization of the research credit carryforwards may be subject to an annual limitation due to the ownership percentage change limitations as definedby the U.S. Internal Revenue Code Section 382, as amended, and similar state provisions. The annual limitation may result in the expiration of the U.S.Federal and state research credit carryforwards before utilization. The Company does not expect any tax credit carryforwards to expire as a result of aSection 382 limitation.The Company applies the provisions of FASB’s guidance on accounting for uncertainty in income taxes. As of January 31, 2019, the Company hadapproximately $37.5 million in unrecognized tax benefits, $31.6 million of which would affect the Company’s effective tax rate if recognized. The followingtable sets forth a reconciliation of the beginning and ending amount of unrecognized tax benefits: Year Ended January 31, 2019 2018 2017 (in thousands) Beginning balance: $34,117 $37,977 $30,211 Additions based on tax positions related to the current year 3,922 7,892 7,830 Additions for tax positions of prior years 109 28 911 Reductions for tax positions in prior years (552) (11,313) — Settlements for prior periods — — — Lapse of applicable statute of limitations (65) (467) (975)Ending balance: $37,531 $34,117 $37,977 The Company classified $6.3 million and $5.2 million of income tax liabilities as other long term liabilities as of January 31, 2019 and 2018,respectively, because payment of cash or settlement is not anticipated within one year from the balance sheet date.90 The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense. The Company recorded$263,000 and $37,000 of interest expense and penalties related to uncertain tax positions for the fiscal years ended January 31, 2019 and 2018, respectively.The Company recorded noncurrent liabilities of $403,000 and $139,000 related to interest and penalties for uncertain tax positions at January 31, 2019 and2018, respectively.The primary jurisdiction where our foreign earnings are derived is the Cayman Islands, where the Company is domiciled. The Company files incometax returns in the U.S. federal jurisdiction as well as many U.S. state and foreign jurisdictions. The tax years 2013 to 2018 remain open to examination by U.S.federal tax authorities. The tax years 2009 to 2018 remain open to examination by U.S. state tax authorities. The tax years 2013 to 2018 remain open toexamination by foreign tax authorities. Fiscal years outside of the normal statute of limitations remain open to audit by tax authorities due to tax attributesgenerated in those earlier years, which have been carried forward and may be audited in subsequent years when utilized.The Company believes that an adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome oftax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’sexpectations, the Company could be required to adjust its provision for income tax in the period such resolution occurs. Although timing of the resolutionand/or closure of audits is highly uncertain, the Company does not believe it is reasonably possible that its unrecognized tax benefits would materiallychange in the next 12 months.As of January 31, 2019, the Company’s long-term income taxes payable, including estimated interest and penalties, was approximately $6.7 million.The Company was unable to make a reasonably reliable estimate of the timing of payments in individual years due to uncertainties in the timing of taxaudits, if any, or their outcomes.On July 27, 2015, in Altera Corp. v. Commissioner, the United States Tax Court issued an opinion invalidating the 2003 final Treasury regulationsthat requires participants in a qualified cost-sharing arrangement to share stock-based compensation. At this time, the U.S. Department of the Treasury has notwithdrawn the requirement to include stock-based compensation in intercompany cost-sharing arrangements from its regulations. In February 2016, the IRSappealed the ruling to the United States Court of Appeals for the Ninth Circuit. Due to the uncertainty related to the final resolution of this issue, theCompany has not recorded tax benefits in its consolidated statements of operations for the fiscal year ended January 31, 2019. The Company will continue tomonitor ongoing developments and potential impacts to its consolidated financial statements. 14. Commitments and ContingenciesThe Company leases its principal and other facilities under operating lease agreements. Net operating lease expenses for the years ended January 31,2019, 2018 and 2017 were approximately $4.6 million, $5.3 million and $7.6 million, respectively. Future annual minimum payments under these operatingagreements with initial lease terms in excess of one year are as follows: As of January 31, 2019 Fiscal Year (in thousands) 2020 $2,592 2021 1,040 2022 356 2023 143 2024 147 Thereafter 576 Total future annual minimum lease payments $4,854 Upon adoption of Accounting Standards Update No. 2015-05, Intangible - Goodwill and Other - Internal-Use Software (Subtopic 350-40), anoncancelable on premise internal-use software license was accounted for as the acquisition of an intangible asset rather than a software license under anoperating lease. For the fiscal years ended January 31, 2019 and 2018, there was $4.7 million and $3.0 million of amortization expense recorded in theconsolidated statements of operations related to these software licenses, respectively. The amortization expense of these software licenses was immaterial forthe fiscal year ended January 31, 2017. 91 Contract Manufacturer CommitmentsThe Company’s components and products are procured and built by independent contract manufacturers based on sales forecasts. These forecastsinclude estimates of future demand, historical trends, analysis of sales and marketing activities, and adjustment of overall market conditions. The Companyregularly issues purchase orders to independent contract manufacturers which are cancelable only upon the agreement between the Company and the third-party. As of January 31, 2019 and 2018, total manufacturing purchase commitments were approximately $28.2 million and $24.3 million, respectively.IndemnificationThe Company, from time to time, in the normal course of business, indemnifies certain vendors with whom it enters into contractual relationships. TheCompany has agreed to hold the other party harmless against third-party claims in connection with the Company’s future products. The Company alsoindemnifies certain customers against third-party claims related to certain intellectual property matters. It is not possible to determine the maximum potentialamount of liability under these indemnification obligations due to the limited history of prior indemnification claims and the unique facts and circumstancesthat are likely to be involved in each particular claim. The Company has not made payments under these obligations and no liabilities have been recorded forthese obligations on the consolidated balance sheets as of January 31, 2019 and 2018, respectively. 15.
