Risk Factor Summary
Our business is subject to significant risks and uncertainties that make an investment in us speculative and risky. Below we summarize what we believe are the principal risk factors but these risks are not the only ones we face, and you should carefully review and consider the full discussion of our risk factors in the section titled “Risk Factors,” together with the other information in this Annual Report on Form 10-K. If any of the following risks actually occurs (or if any of those listed elsewhere in this Annual Report on Form 10-K occur), our business, reputation, financial condition, results of operations, revenue, and future prospects could be seriously harmed. In that event, the market price of our common stock could decline, and you could lose part or all of your investment. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business.
•The COVID-19 pandemic has disrupted and harmed, and may continue to disrupt and harm, our business, financial condition and operating results;
•We depend on cable, satellite and telecommunications (“telco”), and broadcast and media industry spending for our revenue and any material decrease or delay in spending in any of these industries would negatively impact our operating results, financial condition and cash flows;
•The loss of one or more of our key customers, a failure to continue diversifying our customer base, or a decrease in the number of larger transactions could harm our business and our operating results;
•We need to develop and introduce new and enhanced products and solutions in a timely manner to meet the needs of our customers and to remain competitive;
•The markets in which we operate are intensely competitive;
•Our future growth depends on a number of video and broadband industry trends;
•Our software-based cable access product initiatives expose us to certain technology transition risks that may adversely impact our operating results, financial condition and cash flows;
•Our operating results are likely to fluctuate significantly and, as a result, may fail to meet or exceed the expectations of securities analysts or investors, causing our stock price to decline;
•We purchase several key components, subassemblies and modules used in the manufacture or integration of our products from sole or limited sources, and we rely on contract manufacturers and other subcontractors;
•We face risks associated with having outsourced engineering resources located in Ukraine; and
•We rely on resellers, value-added resellers and systems integrators for a significant portion of our revenue, and disruptions to, or our failure to develop and manage our relationships with these customers or the processes and procedures that support them could adversely affect our business.

Item 1. | BUSINESS

We are a leading global provider of (i) versatile and high performance video delivery software, products, system solutions and services that enable our customers to efficiently create, prepare, store, playout and deliver a full range of high-quality broadcast and streaming video services to consumer devices, including televisions, personal computers, laptops, tablets and smart phones and (ii) cable access solutions that enable cable operators to more efficiently and effectively deploy high-speed internet, for data, voice and video services to consumers’ homes.
We operate in two segments, Video and Cable Access. Our Video business provides video processing and production and playout solutions and services worldwide to cable operators and satellite and telco Pay-TV service providers, which we refer to collectively as “service providers,” and to broadcast and media companies, including streaming media companies. Our Video business infrastructure solutions are delivered either through shipment of our products, software licenses or as software-as-a-service (“SaaS”) subscriptions. Our Cable Access business provides cable access solutions and related services, including our CableOS software-based cable access solution, primarily to cable operators globally.
Across our two business segments, we derived approximately 66% of our revenue from the Americas in 2021. The Europe, Middle East and Africa (EMEA) and Asia Pacific (APAC) regions accounted for 25% and 9% of our 2021 revenue, respectively.
Harmonic was initially incorporated in California in June 1988 and was reincorporated in Delaware in May 1995. Our principal executive offices are currently located at 2590 Orchard Parkway, San Jose, California 95131. Our telephone number is (408) 542-2500. Our Internet website is http://www.harmonicinc.com. Other than the information expressly set forth in this Annual Report on Form 10-K, the information contained or referred to on our website is not part of this report.
Industry Overview and Market Trends
Video Business
We believe our customers must continue to employ innovative technologies and services to address key trends in the dynamic video industry.
•Demand for Streaming Services. In the highly competitive video industry, there is strong demand for video content to be captured, processed and streamed to millions of subscribers at scale, and with personalized service features and characteristics. We believe video streaming is, and will continue to be, the most significant trend affecting the video industry for the foreseeable future.
•Demand for Targeted Advertising. Streaming technology makes it possible for streaming platforms to insert personalized targeted advertisements into video streams to consumers. This capability is highly sought after by advertisers and results in significantly higher advertising revenue for video streaming service providers. With streaming viewership continuing to grow rapidly, we believe targeted ad insertion will become a foundational pillar of the video industry in the coming years.
•Streaming of Live Events. In contrast to the constraints of traditional linear broadcast channels, there is effectively no limit to the number of live events that can be streamed or the audience reach of streamed events. Consequently, we believe the number of live events globally that will be streamed to consumers will continue to grow for the foreseeable future.
•Demand for High Quality Video. High quality video for both traditional broadcast television and streaming continues to be an important factor for consumers. Compression technologies such as High Efficiency Video Compression (HEVC) or advances in H.264/AVC codecs, as well as increasing requirements for HDR encoding, will continue to remain a high priority for both broadcast and streaming providers.
•Decline in Broadcast Viewing. Broadcast television viewership will continue to decline as the growth in streaming accelerates. We believe this transition will cause traditional Pay-TV service providers and broadcasters to focus their investments on (i) providing streaming services and (ii) reducing the operational complexities and cost of broadcast television.

Table of Contents
In response to these trends, our customers are:
•expanding their streaming offerings with video-on-demand (VOD) programming, live events and/or linear TV bundles to reach a larger and more global audience;
•utilizing streaming technologies to expand monetization opportunities with personalized and targeted ad insertion;
•continuing to enhance and differentiate their content offerings, consolidate to achieve greater economies of scale and subscriber concentration, and acquire other companies to expand their content libraries and capabilities to develop original content; and
•improving the efficiency and utilization of legacy infrastructure to minimize operational and staffing needs and costs by migrating services to public cloud SaaS or upgrading on-premise equipment with the latest generation of highly dense and functionally rich technologies.
Our Video business strategy is focused on providing our customers with software-based appliances and SaaS platforms to enable and support these trends.
Our Video Markets
Broadcast and Media Companies
•Network broadcasters, programmers and content owners continue to invest in new and enhanced direct-to-consumer streaming platforms, as well as upgrade and improve the efficiencies of their traditional broadcast television services. We believe these companies will utilize new technologies, including public cloud infrastructure and SaaS platforms, to expand their streaming offerings, reach wider audiences, and increase monetization opportunities through personalized advertising, and, in parallel, reduce the complexity and cost of running and operating their traditional broadcast services.
Streaming
•We believe media companies of all sizes will invest heavily in streaming services for the foreseeable future, whether for linear TV, live events or a range of VOD offerings, and that these offerings will be enhanced to include personal and targeted advertisements to increase monetization potential. We believe many of these streaming offerings will be launched by new entrants into the space, in addition to those launched by traditional media companies who have a history and brand in broadcast television.
Service Providers
•Wireline Operators. Cable and telco operators continue to focus on various initiatives to improve and differentiate their service offerings from competing service providers, including bundled digital video, voice and high-speed data services; expansion of streaming service offerings to include linear TV, live events and VOD; upgraded consumer-facing applications; and capacity enhancement of high-speed data services.
•Satellite Operators. Satellite operators around the world have established digital television services that serve tens of millions of subscribers, with the ability to provide tens of thousands of linear channels. We expect satellite operators to increase their investments in their streaming offerings to meet rapidly changing consumption habits and, in parallel, strive to optimize their traditional broadcast operations.
Video Infrastructure Technology Trends
•Acceleration of Streaming Services. We believe the industry will continue to adopt streaming technologies to deliver video content to consumers and, increasingly, utilize public clouds to do so.
•Transformation of Broadcast Infrastructure. We believe the industry will continue to seek to transform existing broadcast infrastructure workflows into more flexible and efficient operations, in order to reduce operational and investment costs. We believe that, in order to maximize cost savings, a material portion of these operations will migrate to public clouds in the coming years, while some customers will upgrade and replace their aging on-premise equipment with next-generation software-based appliances that significantly reduce operational complexity.

Cable Access Business
Industry Challenges
Cable operators continue to face challenges from the rapid growth of demand for broadband bandwidth in their networks, driven primarily by:
•more users with more connected devices and applications;
•bundled digital video, voice and high-speed data services; and
•bandwidth-intensive VOD and streaming video services, and interactive cloud applications.
In addition, the operation of network infrastructure is space, power and personnel intensive. Hardware-centric networks can also be expensive to update or replace. To remain competitive, especially in the face of heightened competition from non-cable service providers such as telcos to deliver gigabit data rates, cable operators need to significantly upgrade existing equipment and network technologies.
Technology Trends
•DOCSIS 3.1. We believe the cable industry will continue to deploy the DOCSIS 3.1 standard, which enables high bandwidth data transfer over existing broadband infrastructure, and we expect future adoption and deployment of the next-generation DOCSIS 4.0 standard.
•Virtualization. We believe cable operators are moving toward more software-driven architectures, which is central to our Cable Access business and product strategy. Virtualized software solutions that are decoupled from underlying hardware and run on commercial-off-the-shelf (COTS) servers and/or cloud-native architectures allow for significantly increased efficiencies, upgradability, configuration flexibility, service agility and scalability not feasible with hardware-centric approaches. We believe a software-based cable access solution can significantly reduce cable operator facility costs, especially costs related to physical space and power consumption, and increase operational efficiency, and that the deployment of these systems will be an important step in cable operators’ transition to all-IP networks.
•Distributed Access Architecture. In addition to centralized cable access solutions, we believe there is accelerating interest in distributed access solutions, particularly in competitive gigabit service markets where cable operators are competing with fiber-to-the-home (FTTH) services and are extending fiber networks deeper into their access networks. A distributed access architecture (DAA) coupled with a software-based cable access solution running on COTS servers at a headend, and the distribution of DAA nodes closer to end users, alleviates the power and space requirements of centralized systems at headend sites due to the fact that the radio frequency (RF) processing is distributed into the field outside of the headend. We believe this distributed architecture will enable service providers to efficiently scale to support data and IP video growth.
•Multiple Access. CableOS is a software-based solution that runs on COTS servers connected to distributed access nodes. Traditionally, the distributed access nodes deliver service to the subscribers over RF signals with DOCSIS. With CableOS, FTTH services over passive optical networks (PON) can be supported with software running on the CableOS servers and with remote optical line termination (OLT) modules plugged into the DAA nodes. The result is that the CableOS solution can support delivering both DOCSIS and PON services to different subscribers. As fiber is pulled deeper into the network, cable operators will have the infrastructure and technology to deliver both traditional cable services and FTTH.
Our Cable Access business strategy is focused on providing our customers with software-based solutions, on a centralized, distributed access or hybrid architecture, to enable and support these technology and industry trends.

Software-based Appliances. Our video processing appliances, which include network management and application software and hardware products, provide our customers with the ability to acquire a variety of signals from different sources and in different protocols in order to deliver a variety of real-time and stored content to their subscribers for viewing on a broad range of devices. Our appliance product families include:
•Encoders. Our high-performance encoders compress video, audio and data channels to low bit rates while maintaining high video quality. Our latest software-based XOS encoders can deliver video in multiple formats, including standard, HD and Ultra HD, and in any video compression standard, including MPEG-2, MPEG-4 AVC and HEVC. This capability allows the encoders to converge workflows targeted for all forms of video delivery, whether broadcast or streaming.
•Video Servers. Our Spectrum family of video server systems are used by broadcast and media companies to create play-to-air television channels. Our customers typically use these video server products to record incoming content from either live feeds or from tapes, encoding that content in real-time into standard media files that are then stored in the server’s file system until the content is needed for playback as part of a scheduled playlist.
•High-density stream processing. We offer high-density, real-time stream processing systems capable of high-performance, high-throughput video processing for mission-critical IP video delivery applications, including multiplexing, scrambling, splicing and blackout source switching.
•Edge processors. Our family of Edge processing platforms allows service providers to acquire content delivered via satellite, IP or terrestrial networks for distribution to their subscribers. These products are used by broadcasters to decode signals backhauled from live news and sporting events in contribution applications, as well as by content owners looking to distribute their content in a controlled manner to a large base of affiliates.
SaaS platforms. Our VOS360 SaaS platforms provide both streaming and channel origination and distribution services in a public cloud environment that is fully managed and operated by our 24/7 DevOps teams. Our SaaS solutions enable the packaging and delivery of high-quality streaming services, including live streaming, VOD, catch-up TV, start-over TV, network-DVR and cloud-DVR services through HTTP streaming to any device, along with dynamic and personal ad insertion. In addition, our VOS360 SaaS platforms enable the transformation of traditional broadcast video workflows into cloud-based workflows, resulting in more efficient and leaner operations for our customers. We continue to see an increasing number of customers seeking to leverage the inherent commercial, operational and infrastructure flexibility offered by our VOS360 SaaS platforms. We also provide an on-premise SaaS offering with our VOS cloud-native software solution for customers seeking to deploy a cloud-like architecture in a private data center.
Cable Access Products and Solutions
Software-Based Cable Access Solution. As demand continues to rapidly grow for high-speed broadband services such as streaming, VOD, time-shift TV and cloud DVR, we believe we can help cable operators take advantage of this opportunity with our CableOS software-based cable access solution, an end-to-end cable access solution consisting of virtualized cloud-native software elements that orchestrate and connect with a variety of Harmonic and third-party indoor and outdoor hardware devices. We believe our CableOS solution delivers unprecedented scalability, agility and cost savings, and enables our customers to migrate to multi-gigabit broadband capacity and the fast deployment of DOCSIS 3.1 data, video and voice services. We believe our solution resolves space and power constraints in cable operator facilities, significantly reduces dependence on hardware upgrade cycles, and reduces total cost of ownership. Our CableOS solution can be deployed based on a centralized, distributed access or hybrid architecture.
CableOS Central Cloud Services. Our CableOS Central Cloud Services is a value-add subscription service for CableOS customers that bundles three elements: (i) 24x7 technical support, (ii) a dedicated customer success team focused on customer satisfaction and retention, and (iii) a CableOS Central Suite SaaS that enhances and simplifies the deployment, monitoring, operation and maintenance of the CableOS solution.

Customers
We sell our products to a variety of cable, satellite and telco, and broadcast and media companies. Set forth below is a representative list of our significant end user and integrator/reseller customers, listed alphabetically, based, in part, on revenue during 2021.

United States | International
AT&T | Access Communications
Charter Communications | America Movil Peru
Comcast | EVS Broadcast
Cox Communications | Groupe Canal
Dish Network | Irdeto BV
Heartland Video Systems | Millicom
Intelsat | Netorium
Scripps Media | NYL Electronica
SES | Tele2 Sverige AB
Turner Broadcasting | Vodafone

Sales to our 10 largest customers in 2021, 2020 and 2019 accounted for approximately 58%, 51% and 49% of our net revenue, respectively. Although we continue to seek to broaden our customer base by penetrating new markets and further expanding internationally, we expect to see continuing industry consolidation and customer concentration.
During 2021, 2020 and 2019, Comcast accounted for 26%, 20% and 23% of our net revenue, respectively. The loss of any significant customer, or any material reduction in orders from any significant customer, or our failure to qualify our new products with any significant customer could materially and adversely affect our operating results, financial condition and cash flows. In addition, we are involved in most quarters in one or more relatively large individual transactions. A decrease in the number of relatively larger individual transactions in which we are involved in any quarter could adversely affect our operating results for that quarter.
Sales and Marketing
In the United States and internationally, we sell our products through our own direct sales force, as well as through independent resellers and systems integrators. Our direct sales team is organized geographically and by major customers and markets to support customer requirements. Our principal sales offices outside of the United States are located in Europe and Asia, and we have support staff in Switzerland and France to support our international customers and operations. Our international resellers are generally responsible for importing our products and providing certain installation, technical support and other services to customers in their territory after receiving training from us.
Our direct sales force and resellers are supported by a highly trained technical staff, which includes application engineers who work closely with our customers to develop technical proposals and design systems to optimize system performance and economic benefits for our customers. Our technical support teams provide a customized set of services, as required, for ongoing maintenance, support-on-demand and training for our customers and resellers, both in our facilities and on-site.
Our product management organization develops strategies for product lines and markets and, in conjunction with our sales force, identifies the evolving technical and application needs of customers so that our product development resources can be most effectively and efficiently deployed to meet anticipated product requirements. Our product management organization is also responsible for setting price levels, demand forecasting and general support of the sales force, particularly at major accounts.
Our corporate marketing organization is responsible for building awareness of the Harmonic brand in our markets and driving engagement with our strategies, solutions and products. The group develops all of our corporate messaging and manages all customer and industry communication channels, including public relations, Web and social media, events and trade shows, as well as demand generation marketing campaigns in conjunction with our sales force.

Manufacturing and Suppliers
We rely on third-party contract manufacturers to assemble our products and the subassemblies and modules for our products. In 2003, we entered into an agreement with Plexus Services Corp. (“Plexus”) to act as our primary contract manufacturer. Plexus accounts for the majority of the products we purchase from our contract manufacturers. This agreement has automatic annual renewals, unless prior notice for nonrenewal is given, and has been automatically renewed for a term expiring in October 2022. We do not generally maintain long-term agreements with any of our contract manufacturers.
Many components, subassemblies and modules necessary for the manufacture or integration of our products are obtained from a sole supplier or a limited group of suppliers. While we expend considerable efforts to qualify additional component sources, consolidation of suppliers in the industry and the small number of viable alternatives have limited the results of these efforts. We do not generally maintain long-term agreements with any of our suppliers.
Intellectual Property
As of December 31, 2021, we held 110 issued U.S. patents and 46 issued foreign patents and had 49 patent applications pending. Although we attempt to protect our intellectual property rights through patents, trademarks, copyrights, licensing arrangements, maintaining certain technology as trade secrets and other measures, we cannot assure you that any patent, trademark, copyright or other intellectual property rights owned by us will not be invalidated, circumvented or challenged, that such intellectual property rights will provide competitive advantages to us, or that any of our pending or future patent applications will be issued with the claims, or the scope of the claims, sought by us, if at all. We cannot assure you that others will not develop technologies that are similar or superior to our technology, duplicate our technology or design around the patents that we own. In addition, effective patent, copyright and trade secret protection may be unavailable or limited in which we do business or may do business in the future.
We enter into confidentiality or license agreements with our employees, consultants, vendors and customers as needed, and generally limit access to, and distribution of, our proprietary information. However, no assurances can be given that these actions will prevent misappropriation of our technology. In addition, if necessary, we are prepared to take legal action, in the future, to enforce our patents and other intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others, or to defend against claims of infringement or invalidity. Any such litigation could result in substantial costs and diversion of resources, including management time, and could negatively affect our business, operating results, financial position and cash flows.
In order to successfully develop and market our products, we may be required to enter into technology development or licensing agreements with third parties. Although many companies are often willing to enter into such technology development or licensing agreements, we cannot assure you that such agreements can be negotiated on reasonable terms or at all. The failure to enter into technology development or licensing agreements, when necessary, could limit our ability to develop and market new products and could harm our business.
Backlog
We schedule production of our products and solutions based upon our backlog, open contracts, informal commitments from customers and sales projections. Our backlog consists of unfilled firm purchase orders by our customers which have not been completed. Approximately 80% to 90% of our backlog and deferred revenue is projected to be converted to revenue within a rolling one-year period. As of December 31, 2021 and 2020, we had backlog, including deferred revenue, of $441.0 million and $290.5 million, respectively. Delivery schedules on such orders may be deferred or canceled for a number of reasons, including reductions in spending by our customers or changes in specific customer requirements. In addition, due to annual budget cycles at many of our customers, the amount of our backlog at any given time is not necessarily indicative of actual revenues for any succeeding period.
Competition
The markets in which our Video and Cable Access businesses operate are extremely competitive and have been characterized by rapid technological change and declining average selling prices in the past. The principal competitive factors in these markets include product performance, functionality and features, reliability, pricing, breadth of product offerings, brand recognition and awareness, sales and distribution capabilities, technical operations, support and services, and customer relationships with our customers. We believe that we compete favorably in each of these categories.

Table of Contents
Our competitors in our Video appliance business include ATEME, MediaKind, Synamedia, Grass Valley, Evertz Microsystems, CommScope and Imagine Communications. Our competitors in our Video SaaS business include Amazon Web Services (AWS), Kaltura, iStreamPlanet, Brightcove and Edgecast.
Our competitors in our Cable Access business include CommScope, Casa Systems, Cisco Systems, Vecima Networks and Calix.
Research and Development
We have historically devoted a significant amount of our resources to research and development. Research and development expenses in 2021, 2020 and 2019 were approximately $102.2 million, $82.5 million and $84.6 million, respectively. Research and development expenses as a percentage of revenue in 2021, 2020 and 2019 were approximately 20%, 22% and 21%, respectively. Our internal research and development activities are conducted primarily in the United States (California, Oregon and New Jersey), France, Israel and Hong Kong. In addition, a portion of our research and development is conducted through third-party partners with engineering resources in Ukraine and India.
Our research and development program is primarily focused on developing new products and solutions, and adding new features and other improvements to existing products and solutions. Our development strategy is to identify features and capabilities in our core software appliances and SaaS platforms that are, or are expected to be, needed by our customers. For our Video business segment, our current research and development efforts are focused on enhancing our streaming capabilities, expanding our targeted advertising technologies, and improving the efficiency and flexibility of broadcast workflows for our traditional appliances and within our SaaS platform. With respect to our Cable Access business segment, our major research and development efforts are focused on cable access solutions for both video and data, particularly the ongoing development of our centralized and distributed CableOS software-based cable access solutions.
Our success in designing, developing, manufacturing and selling new or enhanced products and solutions will depend on a variety of factors, including the identification of market demand for new products and solutions, product selection, timely product design and development, product performance, effective manufacturing and assembly processes, and sales and marketing. Because of the complexity inherent in such research and development efforts, we cannot assure you that we will successfully develop new products and solutions, or that new products and solutions developed by us will achieve market acceptance. Our failure to successfully develop and introduce new products and solutions would materially and adversely affect our business, operating results, financial condition and cash flows.
Human Capital Resources
As of December 31, 2021, we employed a total of 1,267 full time employees, including 490 in research and development, 243 in sales, 271 in service and support, 60 in operations, 87 in marketing (corporate and product) and 116 in a general and administrative capacity. Of those employees, 405 were located in the United States and Canada, and 862 employees were located outside of North America in 25 countries in Central and South America, the Middle East and Africa, Europe and the Asia Pacific region. From time to time, we also employ a number of temporary employees and consultants on a contract basis. Our employees in France are represented by labor unions and an employee works council. None of our other employees are represented by a labor union with respect to their employment with us. We have not experienced any work stoppages, and we consider our relations with our employees to be good.
Competition for qualified personnel in the technology space is intense, and we believe that our future success largely depends upon our continued ability to attract, develop and retain highly skilled individuals across the globe. We believe we offer competitive compensation (including salary, incentive bonus and equity awards) and comprehensive benefits packages in each of our locations around the globe. We aim to create an environment in which our employees can develop and grow, and be recognized for their achievements. We offer training, development and on-demand learning programs to support continuous learning and cultivate talent throughout the company, and promote opportunities for internal mobility and recruitment across functions and geographies. We offer rewards and recognition programs, including spot awards to recognize employee contributions, patent incentive awards, and various functional recognition awards. We regularly conduct employee surveys to gauge employee engagement and satisfaction, and we use the views expressed in the surveys to influence our people strategy and policies.

Item 1A. | RISK FACTORS

Risks Related to Our Business and Our Industry
The COVID-19 pandemic has disrupted and harmed, and may continue to disrupt and harm, our business, financial condition and operating results. We are unable to predict the extent to which the pandemic and related impacts will continue to adversely impact our business, financial condition and operating results and the achievement of our strategic objectives.
Our business, operations and financial performance have been negatively impacted by the COVID-19 pandemic and related public health responses, such as travel bans and restrictions, social distancing requirements and shelter-in-place orders. The pandemic and these related responses have caused, and may continue to cause, decreased demand for our offerings or delayed purchasing decisions by our customers, a global slowdown of economic activity (including a decrease in demand for a broad variety of goods and services), supply chain constraints, and significant volatility and disruption of financial markets.
The COVID-19 pandemic has subjected our operations, financial performance and financial condition to a number of risks, including, but not limited to, those discussed below:
•Declines in demand for our offerings or delays in purchasing decisions as a result of the initial COVID-19 outbreak, which generally occurred in the first half of 2020 and may occur in the future, including as a result of social distancing requirements and shelter-in-place orders limiting our ability to deploy our products, and general economic uncertainty causing a number of businesses to delay or reduce costs;
•Supply chain disruptions and component shortages, exacerbated by overall increased demand for such components, and increased costs related to freight and shipping and securing timely and sufficient supply of certain product components;
•Delays in payments or defaults by our customers or if customers terminate their relationships with us or do not renew their agreements on economic or other terms that are favorable to us;
•Challenges in establishing certain new customer relationships due to travel and meeting restrictions as a result of COVID-19; and
•Our modified business practices in response to the pandemic, such as having most of our employees work remotely, canceling all non-essential employee travel, and cancelling, postponing or holding virtually events and meetings. We may in the future be required to, or choose voluntarily to, take additional actions for the health and safety of our workforce, whether in response to government orders or based on our own determinations of what is in the best interests of our employees; we have been and will continue to be flexible in allowing or limiting access to our various office locations based on local conditions. To the extent our current or future measures result in decreased productivity, harm our company culture or otherwise negatively affect our business, our financial condition and operating results could be adversely affected.
While we have seen improvements in our markets in recent periods, we remain cautious given recent COVID-19 surges across the globe and the impact the pandemic continues to have on global supply chains and the pricing and availability of certain materials and components. The severity, magnitude and duration of the COVID-19 pandemic, the public health responses and its economic consequences continue to be uncertain, dynamic and difficult to predict, and the pandemic’s impact on our operations and financial performance, as well as its impact on our ability to successfully execute our business strategies and initiatives, remains uncertain and difficult to predict. Further, the ultimate impact of the COVID-19 pandemic on our customers and on our business, operations and financial performance, depends on many factors that are not within our control, including, but not limited, to: government, business and individual actions that have been and continue to be taken in response to the pandemic (including restrictions on travel and transport, prohibitions on, or voluntary cancellation of, large gatherings of people and social distancing requirements, and modified workplace activities); the impact of the pandemic and actions taken in response to local or regional economies, travel, and economic activity; the availability of government funding programs; general economic uncertainty in key markets and financial market volatility; volatility in our stock price, global economic conditions and levels of economic growth; and the success of vaccination efforts and pace of recovery in the regions and countries where we conduct business, including the impact of any faltering or unsuccessful reopening of economic activity or subsequent outbreaks of COVID-19. As a result of the uncertainty and disrupted market conditions due to the COVID-19 pandemic, our business, operating results and financial condition has been and may continue to be adversely affected.

Table of Contents
We depend on cable, satellite and telco, and broadcast and media industry spending for our revenue and any material decrease or delay in spending in any of these industries would negatively impact our operating results, financial condition and cash flows.
Our revenue has been derived from worldwide sales to service providers and broadcast and media companies, as well as, in recent years, streaming media companies. We expect that these markets will provide our revenue for the foreseeable future. Demand for our products and solutions will depend on the magnitude and timing of spending by customers in each of these markets for the purpose of creating, expanding or upgrading their systems. These spending patterns are dependent on a variety of factors, including:
•the impact of general economic conditions, actual and projected, including the impact of the COVID-19 pandemic and government and business responses thereto on the global economy and regional economies;
•access to financing;
•annual budget cycles of customers in each of the industries we serve;
•the impact of industry consolidation;
•customers suspending, reducing or shifting spending due to: (i) new video or cable industry standards; (ii) industry trends and technology shifts, such as virtualization and cloud-based solutions, and (iii) new products and solutions, such as products and services based on our VOS software platform or our CableOS software-based cable access solutions;
•delayed or reduced near-term spending as customers transition away from video appliance solutions and adopt new business and operating models enabled by software- and cloud-based solutions, including SaaS unified video processing solutions;
•federal, state, local and foreign government regulation of telecommunications, television broadcasting and streaming media;
•overall demand for communication services and consumer acceptance of new video and data technologies and services;
•competitive pressures, including pricing pressures;
•the impact of fluctuations in currency exchange rates; and
•discretionary end-user customer spending patterns.
In the past, specific factors contributing to reduced spending have included:
•uncertainty and deteriorated market conditions regionally and globally due to the COVID-19 pandemic;
•weak or uncertain economic and financial conditions in the United States or one or more international markets;
•uncertainty related to development of industry technology;
•delays in evaluations of new services, new standards and systems architectures by certain customers;
•emphasis by certain of our customers on generating revenue from existing subscribers or end-customers, rather than from new subscribers or end-customers, through construction, expansion or upgrades;
•a reduction in the amount of capital available to finance projects of our customers and potential customers;
•proposed and completed business combinations and divestitures by our customers and the length of regulatory review of each;
•completion of a new system or significant expansion or upgrade to a system; and
•bankruptcies and financial restructuring of major customers.

In the past, adverse economic conditions in one or more of the geographies in which we offer our products have adversely affected our customers’ spending in those geographies and, as a result, our business. During challenging economic times, such as the ongoing COVID-19 pandemic, and in tight credit markets, many customers have delayed and reduced and may continue to delay or reduce capital expenditures. This has resulted and could continue to result in reductions in revenue from our products, longer sales cycles, difficulties in collection of accounts receivable, slower adoption of new technologies and increased price competition. If global economic and market conditions, or economic conditions in the United States, Europe or other key markets, remain uncertain or deteriorate, we could experience a material and adverse effect on our business, results of operations, financial condition and cash flows. Additionally, since most of our international revenue is denominated in U.S. dollars, global economic and market conditions may impact currency exchange rates and cause our products to become relatively more expensive to customers in a particular country or region, which could lead to delayed or reduced spending in those countries or regions, thereby negatively impacting our business and financial condition.
In addition, industry consolidation has in the past constrained, and may in the future constrain or delay, spending by our customers. Further, if our product portfolio and product development plans do not position us well to capture an increased portion of the spending of customers in the markets on which we focus, our revenue may decline.
As a result of these various factors and potential issues related to customer spending, we may not be able to maintain or increase our revenue in the future, and our operating results, financial condition and cash flows could be materially and adversely affected.
The loss of one or more of our key customers, a failure to continue diversifying our customer base, or a decrease in the number of larger transactions could harm our business and our operating results.
Historically, a significant portion of our revenue has been derived from relatively few customers, due in part to the consolidation of media customers. Sales to our top 10 customers in the fiscal years ended December 31, 2021, 2020 and 2019 accounted for approximately 58%, 51% and 49% of revenue, respectively. Although we continue to seek to broaden our customer base by penetrating new markets and further expanding internationally, we expect to see continuing industry consolidation and customer concentration.
In the fiscal years ended December 31, 2021, 2020 and 2019, Comcast accounted for 26%, 20% and 23% of our net revenue, respectively. Further consolidation in the cable industry could lead to additional revenue concentration for us. The loss of any significant customer, or any material reduction in orders from any other significant customer, or our failure to qualify our new products with any significant customer could materially and adversely affect, either long term or in a particular quarter, our operating results, financial condition and cash flows. Further, while Comcast’s election to license our CableOS software contains commitments in license fees to us, if Comcast deploys our solutions more slowly or at a scale that is lower than we anticipate, our operating results, financial condition and cash flows could be materially and adversely effected.
In addition, we are involved in most quarters in one or more relatively large individual transactions. A decrease in the number of the relatively larger individual transactions in which we are involved in any quarter could materially and adversely affect our operating results for that quarter.
As a result of these and other factors, we may be unable to increase our revenues from some or all of the markets we address, or to do so profitably, and any failure to increase revenues and profits from these customers could materially and adversely affect our operating results, financial condition and cash flows.
We need to develop and introduce new and enhanced products and solutions in a timely manner to meet the needs of our customers and to remain competitive.
All of the markets we address are characterized by continuing technological advancement, changes in customer requirements and evolving industry standards. To compete successfully, we must continually design, develop, manufacture and sell new or enhanced products and solutions that provide increasingly higher levels of performance and reliability and meet our customers’ changing needs. However, we may not be successful in those efforts if, among other things, our products and solutions:
• are not cost effective;
• are not brought to market in a timely manner;
• are not in accordance with evolving industry standards;
• fail to meet market acceptance or customer requirements; or
• are ahead of the needs of their markets.

Table of Contents
If new standards or some of our new products are adopted later than we predict or not adopted at all, or if adoption occurs earlier than we are able to deliver the applicable products or functionality, we risk spending significant research and development time and dollars on products or features that may never achieve market acceptance or that miss the customer demand window and thus do not produce the revenue that a timely introduction would have likely produced.
If we fail to develop and market new and enhanced products and solutions on a timely basis, our operating results, financial condition and cash flows could be materially and adversely affected.
The markets in which we operate are intensely competitive.
The markets for our products are extremely competitive and have been characterized by rapid technological change and declining average sales prices in the past.
Our competitors in our Video appliance business include ATEME, MediaKind, Synamedia, Grass Valley, Evertz Microsystems, CommScope and Imagine Communications. Our competitors in our Video SaaS business include Amazon Web Services (“AWS”), Kaltura, iStreamPlanet, Brightcove and Edgecast. Our competitors in our Cable Access business include CommScope, Casa Systems and Cisco Systems, Vecima Networks and Calix.
A number of our principal business competitors in both of our business segments are substantially larger and/or may have access to greater financial, technical, marketing or other resources than we have. Consolidation in the Video industry has led to the acquisition of a number of our historic competitors over the last several years by private equity firms and by AWS. With respect to our Cable Access business, our competitors are generally substantially larger than us.
In addition, some of our larger competitors may have more long-standing and established relationships with certain domestic and foreign customers. Many of these large enterprises are in a better position to withstand any significant reduction in spending by customers in our markets and may be better able to navigate periods of market uncertainty, such as the uncertainty caused by the COVID-19 pandemic. They often have broader product lines and market focus, and may not be as susceptible to downturns in a particular market. These competitors may also be able to bundle their products together to meet the needs of a particular customer, and may be capable of delivering more complete solutions than we are able to provide. To the extent large enterprises that currently do not compete directly with us choose to enter our markets by acquisition or otherwise, competition would likely intensify.
Further, some of our competitors have offered, and in the future may offer, their products at lower prices than we offer for our competing products or on more attractive financing or payment terms, which has in the past caused, and may in the future cause, us to lose sales opportunities and the resulting revenue or to reduce our prices in response to that competition. Also, some competitors that are smaller than we are have engaged in, and may continue to engage in, aggressive price competition in order to gain customer traction and market share. Reductions in prices for any of our products could materially and adversely affect our operating margins and revenue.
Additionally, certain customers and potential customers have developed, and may continue to develop, their own solutions that may cause such customers or potential customers to not consider our product offerings or to displace our installed products with their own solutions. The growing availability of open source codecs and related software, as well as new server chipsets that incorporate encoding technology, has, in certain respects, lowered the barriers to entry for the video processing industry. The development of solutions by potential and existing customers and the reduction of the barriers to entry to enter the video processing industry could result in increased competition and adversely affect our results of operations and business.
If any of our competitors’ products or technologies were to become the industry standard, our business could be seriously harmed. If our competitors are successful in bringing their products to market earlier than us, or if these products are more technologically capable than ours, our revenue could be materially and adversely affected.
Our future growth depends on a number of video and broadband industry trends.
Technology, industry and regulatory trends and requirements may affect the growth of our business. These trends and requirements include the following:
•convergence, whereby network operators bundle video, voice and data services to consumers, including mobile delivery options;
•continued strong consumer demand for streaming video services;
•continued adoption of public cloud SaaS platforms to stream video content to consumers, as well as for broadcast infrastructure workflows;
•continued growth in targeted advertising as a key revenue source for video streaming service providers;

•the pace of adoption and deployment of high-bandwidth technology, such as DOCSIS 3.x, DOCSIS 4.0, next generation LTE and fiber-to-the-premises (“FTTP”);
•the use of digital video by businesses, governments and educational institutions globally;
•efforts by regulators and governments in the United States and internationally to encourage the adoption of broadband and digital technologies, including 5G broadband networks, as well as to regulate broadband access and delivery;
•the need to develop partnerships with other companies involved in video infrastructure workflow and broadband services;
•the extent and nature of regulatory attitudes towards issues such as network neutrality, competition between operators, access by third parties to networks of other operators, local franchising requirements for telcos to offer video, and other new services, such as mobile video; and
•the outcome of disputes and negotiations between content owners and service providers regarding rights of service providers to store and distribute recorded broadcast content, which outcomes may drive adoption of one technology over another in some cases.
If we fail to recognize and respond to these trends, by timely developing products, features and services required by these trends, we are likely to lose revenue opportunities and our operating results, financial condition and cash flows could be materially and adversely affected.
Our software-based cable access product initiatives expose us to certain technology transition risks that may adversely impact our operating results, financial condition and cash flows.
We believe our CableOS software-based cable access solutions, supporting centralized, DAA or hybrid configurations, will significantly reduce cable headend costs and increase operational efficiency, and are an important step in cable operators’ transition to all-IP networks. If we are unsuccessful in continuing to innovate and develop and deploy our cable access solutions in a timely manner, or are otherwise delayed in making our solutions available to our customers, our business may be adversely impacted, particularly if our competitors develop and market similar or superior products and solutions.
We believe our software-based cable access solutions will continue to replace and make obsolete current CMTS solutions, which is a market our products have historically not addressed, as well as cable edge-QAM products. If demand for our software-based cable access solutions is weaker than expected, our near and long-term operating results, financial condition and cash flows could be adversely impacted. Moreover, if competitors adapt new cable industry technology standards into competing cable access solutions faster than we do, or promulgate a new or competitive architecture for next-generation cable access solutions that renders our CableOS solution obsolete, our business may be adversely impacted.
The sales cycle for our CableOS solutions tends to be long. For cable operators, upgrading or expanding network infrastructure is complex and expensive, and investing in a CableOS solution is a significant strategic decision that may require considerable time to evaluate, test and qualify. Potential customers need to ensure our CableOS solution will interoperate with the various components of its existing network infrastructure, including third-party equipment, servers and software. In addition, since we are a relatively new entrant into the CMTS market, we need to demonstrate significant performance, functionality and/or cost advantages with our CableOS solutions that outweigh customer switching costs. If sales cycles are significantly longer than anticipated or we are otherwise unsuccessful in growing our CableOS sales, our operating results, financial condition and cash flows could be materially and adversely affected.
Our operating results are likely to fluctuate significantly and, as a result, may fail to meet or exceed the expectations of securities analysts or investors, causing our stock price to decline.
Our operating results have fluctuated in the past and are likely to continue to fluctuate in the future, on an annual and a quarterly basis, as a result of several factors, many of which are outside of our control. Some of the factors that may cause these fluctuations include:
•the level and timing of spending of our customers in the United States, Europe and in other markets;
•economic and financial conditions specific to each of the cable, satellite and telco, and broadcast and media industries, as well as general economic and financial market conditions, including the global economic uncertainty caused by the COVID-19 pandemic and government and business responses thereto as well as related supply chain and labor shortage issues;
•changes in market acceptance of and demand for our products or our customers’ services or products;
16

Table of Contents
•the timing and amount of orders, especially from large individual transactions and transactions with our significant customers;
•the mix of our products sold and the effect it has on gross margins;
•the timing of revenue recognition, including revenue recognition on sales arrangements and from transactions with significant service and support components, which may span several quarters;
•our transition to a SaaS subscription model for our Video business, which may cause near-term declines in revenue;
•the timing of completion of our customers’ projects;
•the length of each customer product upgrade cycle and the volume of purchases during the cycle;
•competitive market conditions, including pricing actions by our competitors;
•the level and mix of our domestic and international revenue;
•new product introductions by our competitors or by us;
•uncertainty in both the U.K. and the European Union due to the U.K.’s exit from the European Union and the impact of the U.K.’s transitional period following this exit, which could adversely affect our results, financial condition and prospects;
•changes in domestic and international regulatory environments affecting our business;
•the evaluation of new services, new standards and system architectures by our customers;
•the cost and timely availability to us of components, subassemblies and modules;
•the mix of our customer base, by industry and size, and sales channels;
•changes in our operating and extraordinary expenses;
•the timing of acquisitions and dispositions by us and the financial impact of such transactions;
•impairment of our goodwill and intangibles;
•the impact of litigation, such as related litigation expenses and settlement costs;
•write-downs of inventory and investments;
•changes in our effective federal tax rate, including as a result of changes in our valuation allowance against our deferred tax assets, and changes in our effective state tax rates, including as a result of apportionment;
•changes to tax rules related to the deferral of foreign earnings and compliance with foreign tax rules;
•the impact of applicable accounting guidance on accounting for uncertainty in income taxes that requires us to establish reserves for uncertain tax positions and accrue potential tax penalties and interest; and
•the impact of applicable accounting guidance on business combinations that requires us to record charges for certain acquisition related costs and expenses and generally to expense restructuring costs associated with a business combination subsequent to the acquisition date.
The timing of deployment of our products by our customers can be subject to a number of other risks, including the availability of skilled engineering and technical personnel, the availability of third-party equipment and services, our customers’ ability to negotiate and enter into rights agreements with video content owners that provide our customers with the right to deliver certain video content, and our customers’ need for local franchise and licensing approvals.
We often recognize a substantial portion of our quarterly revenue in the last month of the quarter. We establish our expenditure levels for product development and other operating expenses based on projected revenue levels for a specified period, and expenses are relatively fixed in the short term. Accordingly, even small variations in the timing of revenue, particularly from relatively large individual transactions, can cause significant fluctuations in operating results in a particular quarter.
As a result of these factors and other factors, our operating results in one or more future periods may fail to meet or exceed the expectations of securities analysts or investors. In that event, the trading price of our common stock would likely decline.

We purchase several key components, subassemblies and modules used in the manufacture or integration of our products from sole or limited sources, and we rely on contract manufacturers and other subcontractors.
Our reliance on sole or limited suppliers, particularly foreign suppliers, and our reliance on contractors for manufacturing and installation of our products, involves several risks, including a potential inability to obtain an adequate supply of required components, subassemblies or modules; reduced control over costs, quality and timely delivery of components, subassemblies or modules; supplier discontinuation of components, subassemblies or modules we require; and timely installation of products. In addition, our financial results may be impacted by tariffs imposed by the United States on goods from other countries and tariffs imposed by other countries on U.S. goods. If any such tariffs are imposed on products or components that we import, including those obtained from a sole supplier or a limited group of suppliers, we could experience reduced revenues or may have to raise our prices, either of which could have an adverse effect on our business, financial condition and operating results.
These risks could be heightened during a substantial economic slowdown because our suppliers and subcontractors are more likely to experience adverse changes in their financial condition and operations during such a period. Further, these risks could materially and adversely affect our business if one of our sole sources, or a sole source of one of our suppliers or contract manufacturers, is adversely affected by a natural disaster or the outbreak of disease, epidemics and other pandemics, such as the COVID-19 pandemic, which has adversely impacted and may continue to adversely impact our supply chain. While we expend resources to qualify additional component sources, consolidation of suppliers and the small number of viable alternatives have limited the results of these efforts. Managing our supplier and contractor relationships is particularly difficult during time periods in which we introduce new products and during time periods in which demand for our products is increasing, especially if demand increases more quickly than we expect.
Plexus Services Corp. (“Plexus”), which manufactures our products at its facilities in Malaysia, currently serves as our primary contract manufacturer, and currently accounts for a majority, by dollar amount, of the products that we purchase from our contract manufacturers. Most of the products manufactured by our French and Israeli operations are outsourced to another third-party manufacturer in France and Israel, respectively. From time to time we assess our relationship with our contract manufacturers, and we do not generally maintain long-term agreements with any of our suppliers or contract manufacturers. Our agreement with Plexus has automatic annual renewals, unless prior notice is given by either party, and has been automatically renewed for a term expiring in October 2022.
Difficulties in managing relationships with any of our current contract manufacturers, particularly Plexus, that manufacture our products off-shore, or any of our suppliers of key components, subassemblies and modules used in our products, could impede our ability to meet our customers’ requirements and adversely affect our operating results. An inability to obtain adequate and timely deliveries of our products or any materials used in our products, or the inability of any of our contract manufacturers to scale their production to meet demand, such as the inability of certain of our contract manufacturers to operate at capacity for periods of time due to the COVID-19 pandemic, which may occur again in future periods, or any other circumstance that would require us to seek alternative sources of supply, had negatively impacted and could continue to negatively affect our ability to ship our products on a timely basis, which could damage relationships with current and prospective customers and harm our business and materially and adversely affect our revenue and other operating results. Furthermore, if we fail to meet customers’ supply expectations, our revenue would be adversely affected and we may lose sales opportunities, both short and long term, which could materially and adversely affect our business and our operating results, financial condition and cash flows. Increases, from time to time, in demand on our suppliers and subcontractors from our customers or from other parties have, on occasion, caused delays in the availability of certain components and products. In response, we may increase our inventories of certain components and products and expedite shipments of our products when necessary. These actions could increase our costs and could also increase our risk of holding obsolete or excess inventory, which, despite our use of a demand order fulfillment model, could materially and adversely affect our business, operating results, financial condition and cash flows.
Operational Risks
We rely on resellers, value-added resellers and systems integrators for a significant portion of our revenue, and disruptions to, or our failure to develop and manage our relationships with these customers or the processes and procedures that support them could adversely affect our business.
We generate a significant percentage of our revenue through sales to resellers, value-added resellers (“VARs”) and systems integrators that assist us with fulfillment or installation obligations. We expect that these sales will continue to generate a significant percentage of our revenue in the future. Accordingly, our future success is highly dependent upon establishing and maintaining successful relationships with a variety of channel partners.
18

Table of Contents
We generally have no long-term contracts or minimum purchase commitments with any of our reseller, VAR or system integrator customers, and our contracts with these parties do not prohibit them from purchasing or offering products or services that compete with ours. Our competitors may provide incentives to any of our reseller, VAR or systems integrator customers to favor their products or, in effect, to prevent or reduce sales of our products. Any of our reseller, VAR or systems integrator customers may independently choose not to purchase or offer our products. Many of our resellers, and some of our VARs and system integrators are small, are based in a variety of international locations, and may have relatively unsophisticated processes and limited financial resources to conduct their business. Any significant disruption of our sales to these customers, including as a result of the inability or unwillingness of these customers to continue purchasing our products, or their failure to properly manage their business with respect to the purchase of, and payment for, our products, or their ability to comply with our policies and procedures as well as applicable laws, could materially and adversely affect our business, operating results, financial condition and cash flows. In addition, our failure to continue to establish or maintain successful relationships with reseller, VAR and systems integrator customers could likewise materially and adversely affect our business, operating results, financial condition and cash flows.
We face risks associated with having outsourced engineering resources located in Ukraine.
We outsource a portion of our research and development and product support activities to our third-party partner, GlobalLogic, a Hitachi group company. Through GlobalLogic, we have a significant number of engineering resources located in Kyiv, Ukraine that are dedicated to our Cable Access and Video business segments. Political, social and economic instability and unrest or violence in Ukraine from the ongoing military conflict with the Russian Federation have caused, and may continue to cause, disruptions to the business and operations of GlobalLogic, which could slow or delay the development and support work our outsourced engineering teams are undertaking for us. Any escalation of political tensions, military activity, instability, unrest or conflict could limit or prevent our employees from traveling to, from, or within Ukraine to direct and coordinate our outsourced engineering teams, or cause us to shift all or portions of the development and support work occurring in Ukraine, and/or cause GlobalLogic to relocate personnel to other locations or countries pursuant to its business continuity plans. Any resulting delays could negatively impact our product development and support efforts, operating results and our business.
We may not be able to effectively manage our operations.
As of December 31, 2021, we had 890 employees in our international operations, representing approximately 70% of our worldwide workforce. In recent years, we have expanded our international operations significantly. For example, upon the closing of our acquisition of Thomson Video Networks (“TVN”) on February 29, 2016, we added 438 employees, most of whom were based in France. Our ability to manage our business effectively in the future, inclu ding with respect to any future growth, our operation as both a hardware and increasingly software- and SaaS-centric business, the integration of any acquisition efforts such as our acquisition of TVN, and the breadth of our international operations, will require us to train, motivate and manage our employees successfully, to attract and integrate new employees into our overall operations, to retain key employees and to continue to improve and evolve our operational, financial and management systems. The COVID-19 pandemic has resulted in a significant majority of our employees working mostly or completely from home, which has required us to allocate additional resources towards IT and operations, and which may create new challenges for our operational and management systems. There can be no assurance that we will be successful in any of these efforts, and our failure to effectively manage our operations could have a material and adverse effect on our business, operating results, cash flows and financial condition.
We face risks associated with having facilities and employees located in Israel.
As of December 31, 2021, we maintained facilities in Israel with a total of 226 employees, or approxi mately 18% of our worldwide workforce. Our employees in Israel engage in a number of activities, for both our Video and Cable Access business segments, including research and development, product development, product manag ement, supply chain management for certain product lines and sales activities.

As such, we are directly affected by the political, economic and military conditions affecting Israel. Any significant conflict involving Israel could have a direct effect on our business or that of our Israeli contract manufacturers, in the form of physical damage or injury, restrictions from traveling or reluctance to travel to from or within Israel by our Israeli and other employees or those of our subcontractors, or the loss of Israeli employees to active milit ary duty. Most of our employees in Israel are currently obligated to perform annual reserve duty in the Israel Defense Forces, and approximately 8% of those employees were called for active military duty in 2021. In the event that more of our employees are called to active duty, certain of our research and development activities may be s ignificantly delayed and adversely affected. Further, the interruption or curtailment of trade between Israel and its trading partners, as a result of terrorist attacks or hostilities, conflicts between Israel and any other Middle Eastern country or organization, or any other cause, could significantly harm our business. Additionally, current or future tensions or conflicts in the Middle East could materially and adversely affect our business, operating results, financial condition and cash flows.
In order to manage our growth, we must be successful in addressing management succession issues and attracting and retaining qualified personnel.
Our future success will depend, to a significant extent, on the ability of our management to operate effectively, both individually and as a group. We must successfully manage transition and replacement issues that may result from the departure or retirement of members of our executive management. We cannot provide assurances that changes of management personnel in the future would not cause disruption to operations or customer relationships or a decline in our operating results.
We are also dependent on our ability to retain and motivate our existing highly qualified personnel, in addition to attracting new highly qualified personnel. Competition for qualified management, technical and other personnel is often intense, particularly in Silicon Valley, Israel and Hong Kong where we have significant research and development activities, and we may not be successful in attracting and retaining such personnel. Competitors and others have in the past attempted, and are likely in the future to attempt, to recruit our employees. While our employees are required to sign standard agreements concerning confidentiality, non-solicitation and ownership of inventions, we generally do not have non-competition agreements with our personnel. The loss of the services of any of our key personnel, the inability to attract or retain highly qualified personnel in the future or delays in hiring such personnel, particularly senior management and engineers and other technical personnel, could negatively affect our business and operating results. Furthermore, a certain portion of our personnel in the United States is comprised of foreign nationals whose ability to work for us depends on obtaining the necessary visas. Our ability to hire and retain foreign nationals in the United States, and their ability to remain and work in the United States, is affected by various laws and regulations, including limitations on the availability of visas. Changes in United States laws or regulations affecting the availability of visas have, and may continue to adversely affect, our ability to hire or retain key personnel and as a result may impair our operations.
Our products include third-party technology and intellectual property, and our inability to acquire new technologies or use third-party technology in the future could harm our business.
In order to successfully develop and market certain of our planned products, we may be required to enter into technology development or licensing agreements with third parties. Although companies with technology useful to us are often willing to enter into technology development or licensing agreements with respect to such technology, we cannot provide assurances that such agreements may be negotiated on commercially reasonable terms, or at all. The failure to enter, or a delay in entering, into such technology development or licensing agreements, when necessary or desirable, could limit our ability to develop and market new products and could materially and adversely affect our business.
We incorporate certain third-party technologies, including software programs, into our products, and, as noted, intend to utilize additional third-party technologies in the future. In addition, the technologies that we license may not operate properly or as specified, and we may not be able to secure alternatives in a timely manner, either of which could harm our business. We could face delays in product releases until alternative technology can be identified, licensed or developed, and integrated into our products, if we are able to do so at all. These delays, or a failure to secure or develop adequate technology, could materially and adversely affect our business, operating results, financial condition and cash flows.

Cybersecurity incidents, including data security breaches or computer viruses, could harm our business by disrupting our business operations, compromising our products and services, damaging our reputation or exposing us to liability.
Cyber criminals and hackers may attempt to penetrate our network security, misappropriate our proprietary information or cause business interruptions. Because the techniques used by such computer programmers to access or sabotage networks change frequently and may not be recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. In the past, we have faced compromises to our network security, and companies are facing additional attacks as workforces become more distributed following shelter-in-place orders. While we have invested in and continue to update our network security and cybersecurity infrastructure and systems, if our cybersecurity systems fail to protect against unauthorized access, sophisticated cyber-attacks, phishing schemes, ransomware, data protection breaches, computer viruses, denial-of-service attacks and similar disruptions from unauthorized tampering or human error, our ability to conduct our business effectively could be damaged in a number of ways, including:
•our intellectual property and other proprietary data, or financial assets, could be stolen;
•our ability to manage and conduct our business operations could be seriously disrupted;
•defects and security vulnerabilities could be introduced into our product, software and SaaS offerings, thereby damaging the reputation and perceived reliability and security of our products; and
•personally identifiable data of our customers, employees and business partners could be compromised.
Should any of the above events occur, our reputation, competitive position and business could be significantly harmed, and we could be subject to claims for liability from customers, third parties and governmental authorities. Additionally, we could incur significant costs in order to upgrade our cybersecurity systems and remediate damages. Consequently, our business, operating results, financial condition and cash flows could be materially and adversely affected. In addition, our business operations utilize and rely upon numerous third-party vendors, manufacturers, solution providers, partners and consultants, and any failure of such third parties’ cybersecurity measures could materially and adversely affect or disrupt our business.
Our operating results could be adversely affected by natural disasters affecting us or impacting our third-party manufacturers, suppliers, resellers or customers.
Our corporate headquarters is located in California, which is prone to earthquakes. In addition, climate change is contributing to an increase in erratic weather patterns globally and intensifying the impact of certain types of catastrophes, such as floods and wildfires. We have employees, consultants and contractors located in regions and countries around the world. In the event that any of our business, sales or research and development centers or offices in the United States or internationally are adversely affected by an earthquake, flood, wildfire or by any other natural disaster, we may sustain damage to our operations and properties, which could cause a sustained interruption or loss of affected operations, and cause us to suffer significant financial losses.
We rely on third-party contract manufacturers for the production of our products. Any significant disruption in the business or operations of such manufacturers or of their or our suppliers could adversely impact our business. Our principal contract manufacturers and several of their and our suppliers and our resellers have operations in locations that are subject to natural disasters, such as severe weather, tsunamis, floods, fires and earthquakes, which could disrupt their operations and, in turn, our operations.
In addition, if there is a natural disaster in any of the locations in which our significant customers are located, we face the risk that our customers may incur losses or sustained business interruption, or both, which may materially impair their ability to continue their purchase of products from us. Accordingly, natural disaster in one of the geographies in which we, or our third-party manufacturers, their or our suppliers or our customers, operate could have a material and adverse effect on our business, operating results, cash flows and financial condition.

Financial, Transactional and Tax Risks
We may need additional capital in the future and may not be able to secure adequate funds at all or on terms acceptable to us.
We engage in the design, development and manufacture and sale of a variety of video and cable access products and system solutions, which has required, and will continue to require, significant research and development expenditures.
We are monitoring and managing our cash position in light of ongoing market conditions due to COVID-19. We believe that our existing cash of approximately $133.4 million at December 31, 2021 will satisfy our cash requirements for at least the next 12 months. However, we may need to raise additional funds to take advantage of presently unanticipated strategic opportunities, satisfy our other cash requirements from time to time, or strengthen our financial position. Our ability to raise funds may be adversely affected by a number of factors, including factors beyond our control, such as weakness in the economic conditions in markets in which we sell our products and continued uncertainty in financial, capital and credit markets. There can be no assurance that equity or debt financing will be available to us on reasonable terms, if at all, when and if it is needed.
We may raise additional financing through public or private equity or convertible debt offerings, debt financings, or corporate partnership or licensing arrangements. To the extent we raise additional capital by issuing equity securities or convertible debt, our stockholders may experience dilution, and any new equity or convertible debt securities we issue could have rights, preferences, and privileges superior to holders of our common stock. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our technologies or products, or grant licenses on terms that are not favorable to us. To the extent we raise capital through debt financing arrangements, we may be required to pledge assets or enter into covenants that could restrict our operations or our ability to incur further indebtedness and the interest on such debt may adversely affect our operating results.
If adequate capital is not available, or is not available on reasonable terms, when needed, we may not be able to take advantage of acquisition or other market opportunities, to timely develop new products, or to otherwise respond to competitive pressures.
Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial debt.
Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including the 2022 Notes and the 2024 Notes (together, the “Notes”), or to make cash payments in connection with any conversion of the Notes or in connection with any repurchase of Notes upon the occurrence of a fundamental change before the applicable maturity date at a repurchase price equal to 100% of the principal amount of such Notes to be repurchased, plus any accrued and unpaid interest thereon, as set forth in the applicable indenture governing the Notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness, including the Notes will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations, including the Notes.
In addition, our ability to repurchase the Notes of the applicable series or to pay cash upon conversions of the Notes or at their respective maturity may be limited by law, regulatory authority, or agreements governing our future indebtedness. Our failure to repurchase such Notes at a time when the repurchase is required by the applicable indenture governing the Notes or to pay cash upon conversions of such Notes or at their respective maturity as required by the applicable indenture governing the Notes would constitute a default under such indenture. A default under such indenture, or the fundamental change itself, could also lead to a default under agreements governing our future indebtedness. Moreover, the occurrence of a fundamental change under the applicable indenture governing the Notes could constitute an event of default under any such agreement. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase such series of Notes or make cash payments upon conversions thereof.

Despite our current debt levels, we may still incur substantially more debt or take other actions which would intensify the risks discussed above.
Despite our current consolidated debt levels, we and our subsidiaries may be able to incur substantial additional debt in the future, subject to the restrictions contained in our debt instruments, some of which may be secured debt. We are not restricted under the terms of each indenture governing the Notes from incurring additional debt, securing existing or future debt, recapitalizing our debt or taking a number of other actions that are not limited by the terms of the indenture governing the notes that could have the effect of diminishing our ability to make payments on our debt (including the Notes) when due. In addition, the Credit Agreement we entered into with JPMorgan Chase Bank, N.A., as lender, and Harmonic International GmbH, as co-borrower, on December 19, 2019 and amended in 2020, permits us to incur certain additional indebtedness and grant certain liens on our assets that could intensify the risks discussed above.
The conditional conversion feature of the Notes, if triggered, may adversely affect our financial condition and operating results.
In the event the conditional conversion feature of the Notes is triggered, holders of Notes will be entitled under the respective indenture governing such Notes to convert the Notes at any time during specified periods at their option. During the fourth quarter of fiscal 2021, the Company made an irrevocable election under the terms of the indentures governing each series of the Notes to settle the principal portion of such Notes solely with cash and may pay or deliver, as the case may be, any conversion value greater than the principal amount in cash, shares of common stock or a combination thereof, at the Company’s election. Accordingly, if one or more holders elect to convert their Notes, we would be required to settle the principal portion of our conversion obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their series of Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of such series of Notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.
The accounting method for convertible debt securities that may be settled in cash, such as the Notes, could have a material effect on our reported financial results.
In May 2008, the Financial Accounting Standards Board (“FASB”) issued FASB Staff Position No. APB 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement), which has subsequently been codified as Accounting Standards Codification 470-20, Debt with Conversion and Other Options (“ASC 470-20”), an entity must separately account for the liability and equity components of the convertible debt instruments (such as the Notes) that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer’s economic interest cost. The effect of ASC 470-20 on the accounting for each series of the Notes is that the equity component is required to be included in the additional paid-in capital section of stockholders’ equity on our consolidated balance sheet at the issuance date, and the value of the equity component is treated as debt discount for purposes of accounting for the debt component of each series of Notes. This requires us to record a greater amount of non-cash interest expense as a result of the amortization of the discounted carrying value of each series of Notes to their face amount over the respective terms of the Notes. We report lower net income in our financial results because ASC 470-20 requires interest to include both the amortization of the debt discount and the instrument’s coupon interest rate, which could adversely affect our future financial results or the trading price of our common stock.
In addition, under certain circumstances, convertible debt instruments (such as the Notes) that may be settled entirely or partly in cash are currently accounted for utilizing the treasury stock method, the effect of which is that the shares issuable upon conversion of the Notes are not included in the calculation of diluted earnings per share except to the extent that the conversion value of the Notes exceeds their principal amount. Under the treasury stock method, for diluted earnings per share purposes, the transaction is accounted for as if the shares of common stock that would be necessary to settle such excess, if we elected to settle such excess in shares, are issued.
In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments in an Entity’s Own Equity, which simplifies the accounting for convertible instruments and contracts on an entity’s own equity. Among other changes, ASU No. 2020-06 removes from United States generally accepted accounting principles (“U.S. GAAP”) the liability and equity separation model for convertible instruments with a cash conversion feature, and as a result, after adoption, entities will no longer separately present in equity an embedded conversion feature for such debt. Similarly, the embedded conversion feature will no longer be amortized into income as interest expense over the life of the instrument. Instead, entities will account for a convertible debt instrument wholly as debt unless (1) a convertible instrument contains features that require bifurcation as a derivative under ASC Topic 815, Derivatives and Hedging, or (2) a convertible debt instrument was issued at a substantial premium. This ASU is effective for interim and annual periods beginning after December 15, 2021 and can be adopted either on a modified retrospective or full retrospective basis.

The Company adopted this ASU on January 1, 2022 on a modified retrospective basis. The adoption is expected to reduce additional paid-in capital and convertible debt (mezzanine equity) by approximately $32.2 million and $0.9 million, respectively, due to the recombination of the equity conversion component of outstanding convertible debt, which was initially separated and recorded in stockholder’s equity, and to remove the remaining debt discount of approximately $15.2 million related to this previous separation. The net effect of these adjustments will be recorded as a reduction in the balance of the opening accumulated deficit as of January 1, 2022.
The Company currently expects the adoption of this ASU will result in the reduction of non-cash interest expense for the year ending December 31, 2022 and future periods until the settlement of the remaining outstanding Notes. The required use of the if-converted method to calculate the impact of convertible notes on diluted earnings per share is not expected to have a material impact. During the fourth quarter of fiscal 2021, the Company and the trustee for 2022 Notes and 2024 Notes entered into supplemental indentures for both 2022 Notes and 2024 Notes. Pursuant to the supplemental indentures, the Company eliminated its option to settle the principal of the Notes in shares of the Company's common stock upon conversion. Accordingly, the dilutive effect of the Company's 2022 Notes and 2024 Notes will be limited to the conversion premium. The adoption of this ASU will have no impact on the consolidated statement of cash flows.
We have made, and may continue to make, acquisitions, and any acquisition could disrupt our operations, cause dilution to our stockholders and materially and adversely affect our business, operating results, cash flows and financial condition.
As part of our business strategy, from time to time we have acquired, and we may continue to acquire, businesses, technologies, assets and product lines that we believe complement or expand our existing business. Acquisitions involve numerous risks, including the following:
•unanticipated costs or delays associated with an acquisition;
•difficulties in the assimilation and integration of acquired operations, technologies and/or products;
•potential disruption of our business and the diversion of management’s attention from the regular operations of the business during the acquisition process;
•the challenges of managing a larger and more geographically widespread operation and product portfolio after the closing of the acquisition;
•potential adverse effects on new and existing business relationships with suppliers, contract manufacturers, resellers, partners and customers;
•compliance with regulatory requirements, such as local employment regulations and organized labor in France;
•risks associated with entering markets in which we may have no or limited prior experience;
•the potential loss of key employees of acquired businesses and our own business as a result of integration;
•difficulties in bringing acquired products and businesses into compliance with applicable legal requirements in jurisdictions in which we operate and sell products;
•impact of known potential liabilities or unknown liabilities, including litigation and infringement claims, associated with companies we acquire;
•substantial charges for acquisition costs or for the amortization of certain purchased intangible assets, deferred stock compensation or similar items;
•substantial impairments to goodwill or intangible assets in the event that an acquisition proves to be less valuable than the price we paid for it;
•difficulties in establishing and maintaining uniform financial and other standards, controls, procedures and policies;
•delays in realizing, or failure to realize, the anticipated benefits of an acquisition; and
•the possibility that any acquisition may be viewed negatively by our customers or investors or the financial markets.

Competition within our industry for acquisitions of businesses, technologies, assets and product lines has been, and is likely to continue to be, intense. As such, even if we are able to identify an acquisition that we would like to consummate, we may not be able to complete the acquisition on commercially reasonable terms or because the target chooses to be acquired by another company. Furthermore, in the event that we are able to identify and consummate any future acquisitions, we may, in each of those acquisitions:
•issue equity securities which would dilute current stockholders’ percentage ownership;
•incur substantial debt to finance the acquisition or assume substantial debt in the acquisition;
•incur significant acquisition-related expenses;
•assume substantial liabilities, contingent or otherwise; or
•expend significant cash.
These financing activities or expenditures could materially and adversely affect our operating results, cash flows and financial condition or the price of our common stock. Alternatively, due to difficulties in the capital or credit markets at the time, we may be unable to secure capital necessary to complete an acquisition on reasonable terms, or at all. Moreover, even if we were to obtain benefits from acquisitions in the form of increased revenue and earnings per share, there may be a delay between the time the expenses associated with an acquisition are incurred and the time we recognize such benefits.
In addition to the risks outlined above, if we are unable to successfully receive payment of any significant portion of our existing French R&D credit receivables from the French authority as expected, or are unable to successfully apply for or otherwise obtain the financial benefit of new French R&D credits in future years, our ability to achieve the anticipated benefits of the acquisition as well as our business, operating results and financial condition could be adversely affected.
As of December 31, 2021, we had approximately $240.2 million of goodwill rec orded on our balance sheet associated with prior acquisitions. In the event we determine that our goodwill is impaired, we would be required to write down all or a portion of such goodwill, which could result in a material non-cash charge to our results of operations in the period in which such write-down occurs.
If we are unable to successfully address one or more of these risks, our business, operating results, financial condition and cash flows could be materially and adversely affected.
We may sell one or more of our product lines, from time to time, as a result of our evaluation of our products and markets, and any such divestiture could adversely affect our continuing business and our expenses, revenues, results of operation, cash flows and financial position.
We periodically evaluate our various product lines and may, as a result, consider the divestiture of one or more of those product lines. We have sold product lines in the past, and any prior or future divestiture could adversely affect our continuing business and expenses, revenues, results of operations, cash flows and financial position.
Divestitures of product lines have inherent risks, including the expense of selling the product line, the possibility that any anticipated sale will not occur, delays in closing any sale, the risk of lower-than-expected proceeds from the sale of the divested business, unexpected costs associated with the separation of the business to be sold from the seller’s information technology and other operating systems, and potential post-closing claims for indemnification or breach of transition services obligations of the seller. Expected cost savings, which are offset by revenue losses from divested businesses, may also be difficult to achieve or maximize due to the seller’s fixed cost structure, and a seller may experience varying success in reducing fixed costs or transferring liabilities previously associated with the divested business.
The nature of our business requires the application of complex revenue and expense recognition rules and the current legislative and regulatory environment affecting generally accepted accounting principles is uncertain. Significant changes in current principles could affect our financial statements going forward and changes in financial accounting standards or practices may cause adverse, unexpected financial reporting fluctuations and harm our operating results.
U.S. GAAP are subject to interpretation by the FASB, the SEC and various bodies formed to promulgate and interpret appropriate accounting principles. We are also subject to evolving rules and regulations of the countries in which we do business. Changes to accounting standards or interpretations thereof may result in different accounting principles under U.S. GAAP that have a significant effect on our reported financial results and require us to incur costs and expenses in order to comply with the updated standards or interpretations.
In addition, we have in the past and may in the future need to modify our customer contracts, accounting systems and processes when we adopt future or proposed changes in accounting principles. The cost and effect of these changes may negatively impact our results of operations during the periods of transition.

Fluctuations in our future effective tax rates could affect our future operating results, financial condition and cash flows.
We are required to periodically review our deferred tax assets and determine whether, based on available evidence, a valuation allowance is necessary. The realization of our deferred tax assets, which are predominantly in the United States, is dependent upon the generation of sufficient U.S. and foreign taxable income in the future to offset these assets. Based on our evaluation, we recorded a net increase in valuation allowance of $0.3 million and $6.7 million in 2021 and 2020, respectively, against the net deferred tax assets. The increases in valuation allowance in 2021 and 2020 were offset by the valuation allowance release of $9.6 million and $2.6 million, respectively, related to deferred taxes for certain foreign jurisdictions. The Company reduced its valuation allowance in 2021 based on continued improved operating results over the past few years and expectations about generating foreign taxable income in the future. Changes in the amount of the U.S. and foreign jurisdictions valuation allowance could result in a material non-cash expense or benefit in the period in which the valuation allowance is adjusted and our results of operations could be materially affected.
The calculation of tax liabilities involves dealing with uncertainties in the application of complex global tax regulations. We recognize potential liabilities for anticipated tax audit issues in the United States and other tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes will be due. In the event we determine that it is appropriate to create a reserve or increase an existing reserve for any such potential liabilities, the amount of the additional reserve will be charged as an expense in the period in which it is determined. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when we determine the liabilities are no longer necessary. If the estimate of tax liabilities proves to be less than the ultimate tax assessment for the applicable period, a further charge to expense in the period such shortfall is determined would result. Either such charge to expense could have a material and adverse effect on our operating results for the applicable period.
Our future effective income tax rates could be adversely affected if tax authorities challenge our international tax structure or if the relative mix of U.S. and international income changes for any reason. Accordingly, there can be no assurance that our effective income tax rate will be less than the U.S. federal statutory rate in future periods.
Legal, Regulatory and Compliance Risks
We or our customers may face intellectual property infringement claims from third parties.
Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. In particular, leading companies in the telecommunications industry have extensive patent portfolios. Also, patent infringement claims and litigation by entities that purchase or control patents, but do not produce goods or services covered by the claims of such patents (so-called “non-practicing entities” or “NPEs”), have increased rapidly over the last decade or so. From time to time, third parties, including NPEs, have asserted, and may assert in the future, patent, copyright, trademark and other intellectual property rights against us or our customers, and have initiated audits to determine whether we have missed royalty payments for technology that we license. Our suppliers and their customers, including us, may have similar claims asserted against them. A number of third parties, including companies with greater financial and other resources than us, have asserted patent rights to technologies that are important to us.
Any intellectual property litigation, regardless of its outcome, could result in substantial expense and significant diversion of the efforts of our management and technical personnel. An adverse determination in any such proceeding could subject us to significant liabilities and temporary or permanent injunctions and require us to seek licenses from third parties or pay royalties that may be substantial. Furthermore, necessary licenses may not be available on terms satisfactory to us, or at all. An unfavorable outcome on any such litigation matter could require that we pay substantial damages, could require that we pay ongoing royalty payments, or could prohibit us from selling certain of our products. Any such outcome could have a material and adverse effect on our business, operating results, financial condition and cash flows.
Our suppliers and customers may have intellectual property claims relating to our products asserted against them. We have agreed to indemnify some of our suppliers and most of our customers for patent infringement relating to our products. The scope of this indemnity varies, but, in some instances, includes indemnification for damages and expenses (including reasonable attorney’s fees) incurred by the supplier or customer in connection with such claims. If a supplier or a customer seeks to enforce a claim for indemnification against us, we could incur significant costs defending such claim, the underlying claim or both. An adverse determination in either such proceeding could subject us to significant liabilities and have a material and adverse effect on our operating results, cash flows and financial condition.
26

Table of Contents
We may be the subject of litigation which, if adversely determined, could harm our business and operating results.
We may be subject to claims arising in the normal course of business. The costs of defending any litigation, whether in cash expenses or in management time, could harm our business and materially and adversely affect our operating results and cash flows. An unfavorable outcome on any litigation matter could require that we pay substantial damages, or, in connection with any intellectual property infringement claims, could require that we pay ongoing royalty payments or prohibit us from selling certain of our products. In addition, we may decide to settle any litigation, which could cause us to incur significant settlement costs. A settlement or an unfavorable outcome on any litigation matter could have a material and adverse effect on our business, operating results, financial condition and cash flows.
Our failure to adequately protect our proprietary rights and data may adversely affect us.
At December 31, 2021, we he ld 110 issued U.S. patents and 46 issued foreign patents, and had 49 paten t applications pending. Although we attempt to protect our intellectual property rights through patents, trademarks, copyrights, licensing arrangements, maintaining certain technology as trade secrets and other measures, we can give no assurances that any patent, trademark, copyright or other intellectual property rights owned by us will not be invalidated, circumvented or challenged, that such intellectual property rights will provide competitive advantages to us, or that any of our pending or future patent applications will be issued with the scope of the claims sought by us, if at all. We can give no assurances that others will not develop technologies that are similar or superior to our technologies, duplicate our technologies or design around the patents that we own. In addition, effective patent, copyright and trade secret protection may be unavailable or limited in certain foreign countries in which we do business or may do business in the future.
We may enter into confidentiality or license agreements with our employees, consultants, and vendors and our customers, as needed, and generally limit access to, and distribution of, our proprietary information. Nevertheless, we cannot provide assurances that the steps taken by us will prevent misappropriation of our technology. In addition, we have taken in the past, and may take in the future, legal action to enforce our patents and other intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others, or to defend against claims of infringement or invalidity. Such litigation could result in substantial costs and diversion of management time and other resources, and could materially and adversely affect our business, operating results, financial condition and cash flows.
Our use of open source software in some of our products may expose us to certain risks.
Some of our products contain software modules licensed for use from third-party authors under open source licenses. Use and distribution of open source software may entail greater risks than use of third-party commercial software, as open source licensors generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. Some open source licenses contain requirements that we make available source code for modifications or derivative works we create based upon the type of open source software we use. If we combine our proprietary software with open source software in a certain manner, we could, under certain of the open source licenses, be required to release the source code of our proprietary software to the public. This could allow our competitors to create similar products with lower development effort and in less time and ultimately could result in a loss of product sales for us.
Although we monitor our use of open source closely, it is possible our past, present or future use of open source has triggered or may trigger the foregoing requirements. Furthermore, the terms of many open source licenses have not been interpreted by U.S. courts, and there is a risk that such licenses could be construed in a manner that could impose unanticipated conditions or restrictions on our ability to commercialize our products. In such event, we could be required to seek licenses from third parties in order to continue offering our products, to re-engineer our products or to discontinue the sale of our products in the event re-engineering cannot be accomplished on a timely basis, any of which could materially and adversely affect our operating results, financial condition and cash flows.

We are subject to import and export control and trade and economic sanction laws and regulations that could subject us to liability or impair our ability to compete in international markets.
Our products are subject to U.S. export control laws, and may be exported outside the U.S. only with the required export license or through an export license exception, in most cases because we incorporate encryption technology into certain of our products. We are also subject to U.S. trade and economic sanction regulations which include prohibitions on the sale or supply of certain products and services to the United States embargoed or sanctioned countries, governments, persons and entities. In addition, various countries regulate the import of certain technology and have enacted laws that could limit our ability to distribute our products, or could limit our customers’ ability to implement our products, in those countries. Although we take precautions and have processes in place to prevent our products and services from being provided in violation of such laws, our products may have been in the past, and could in the future be, provided inadvertently in violation of such laws, despite the precautions we take. In March 2020, we received an administrative subpoena from the U.S. Treasury Department’s office of Foreign Assets Control (“OFAC”) requesting information about transactions involving Iran. The transactions were by the French company TVN, which we acquired in early 2016. Pursuant to regulations that remained in place until 2018, foreign subsidiaries of U.S. companies were allowed to engage in transactions with Iran if certain requirements were met. Harmonic is fully cooperating in the OFAC investigation. If we are found to have violated U.S. export control laws as a result of the pending OFAC investigation or future investigations, we and certain of our employees could be subject to civil or criminal penalties, including the possible loss of export privileges, monetary penalties, and, in extreme cases, imprisonment of responsible employees for knowing and willful violations of these laws. While we do not anticipate the impact of the OFAC investigation to be material on our business, our business and operating results could be adversely affected through penalties, reputational harm, loss of access to certain markets, or otherwise.
In addition, we may be subject to customs duties that could have a significant adverse impact on our operating results or, if we are able to pass on the related costs in any particular situation, would increase the cost of the related product to our customers. As a result, the future imposition of significant increases in the level of customs duties or the creation of import quotas on our products in Europe or in other jurisdictions, or any of the limitations on international sales described above, could have a material adverse effect on our business, operating results, financial condition and cash flows. Further, some of our customers in Europe have been, or are being, audited by local governmental authorities regarding the tariff classifications used for importation of our products. Import duties and tariffs vary by country and a different tariff classification for any of our products may result in higher duties or tariffs, which could have an adverse impact on our operating results and potentially increase the cost of the related products to our customers.
Our business and industry are subject to various laws and regulations that could adversely affect our business, operating results, cash flows and financial condition.
Our business and industry are regulated under various federal, state, local and international laws. For example, we are subject to environmental regulations such as the European Union’s Waste Electrical and Electronic Equipment (“WEEE”) and Restriction on the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (“RoHS”) directives and similar legislation enacted in other jurisdictions worldwide. Our failure to comply with these laws could result in our being directly or indirectly liable for costs, fines or penalties and third-party claims, and could jeopardize our ability to conduct business in such regions and countries. We expect that our operations will be affected by other new environmental laws and regulations on an ongoing basis. Although we cannot predict the ultimate impact of any such new laws and regulations, they would likely result in additional costs, and could require that we redesign or change how we manufacture our products, any of which could have a material and adverse effect on our operating results, financial condition and cash flows.
We are subject to the Sarbanes-Oxley Act of 2002 which, among other things, requires an annual review and evaluation of our internal control over financial reporting. If we conclude in future periods that our internal control over financial reporting is not effective or if our independent registered public accounting firm is unable to provide an unqualified attestation as of future year-ends, we may incur substantial additional costs in an effort to correct such problems, and investors may lose confidence in our financial statements, and our stock price may decrease in the short term, until we correct such problems, and perhaps in the long term, as well.
28

Table of Contents
We are subject to requirements under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 that require us to conduct research, disclose, and report whether or not our products contain certain conflict minerals sourced from the Democratic Republic of Congo or its surrounding countries. The implementation of these requirements could adversely affect the sourcing, availability, and pricing of the materials used in the manufacture of components used in our products. In addition, we may incur certain additional costs to comply with the disclosure requirements, including costs related to conducting diligence procedures to determine the sources of conflict minerals that may be used or necessary to the production of our products and, if applicable, potential changes to products, processes or sources of supply as a consequence of such verification activities. It is also possible that we may face reputational harm if we determine that certain of our products contain minerals not determined to be conflict-free and/or we are unable to alter our products, processes or sources of supply to avoid such materials.
Changes in telecommunications legislation and regulations in the United States and other countries could affect our sales and the revenue we are able to derive from our products. In particular, on December 14, 2017, the U.S. Federal Communications Commission (“FCC”) voted to repeal the “net neutrality” rules and return to a “light-touch” regulatory framework. The FCC’s new rules, which took effect in June 2018, granted providers of broadband internet access services greater freedom to make changes to their services, including, potentially, changes that may discriminate against or otherwise harm our business. However, a number of parties have appealed these rules, which appeals are currently being reviewed by the D.C. Circuit Court of Appeals; thus the future impact of the FCC's repeal and any changes thereto remains uncertain. Additionally, on September 30, 2018, California enacted the California Internet Consumer Protection and Net Neutrality Act of 2018. Since the FCC repealed its nationwide regulations, seven states have also enacted a state-level net neutrality law and a number of other states are considering legislation or executive actions that would regulate the conduct of broadband providers. We cannot predict whether the FCC order or state initiatives will be modified, overturned, or vacated by legal action of the court, federal legislation, or the FCC. The repeal of the net neutrality rules or other regulations dealing with access by competitors to the networks of incumbent operators could slow or stop infrastructure and services investments or expansion by service providers. Increased regulation of our customers’ pricing or service offerings could limit their investments and, consequently, revenue from our products. The impact of new or revised legislation or regulations could have a material adverse effect on our business, operating results, financial condition and cash flows.
We depend significantly on our international revenue and are subject to the risks associated with international operations, including those of our resellers, contract manufacturers and outsourcing partners, which may negatively affect our operating results.
Revenue derived from cu stomers outside of the United States in the fiscal years ended December 31, 2021, 2020 and 2019 represented approximatel y 44%, 49% and 50% of our revenue, respectively. Although no assurance can be given with respect to international sales growth in any one or more regions, we expect that international revenue will likely continue to represent, from year to year, a majority, and potentially increasing, percentage of our annual revenue for the foreseeable future. A significant percentage of our revenue is generated from sales to resellers, VARs and systems integrators, particularly in emerging market countries. Furthermore, the majority of our employees are based in our international offices and locations, and most of our contract manufacturing occurs outside of the United States. In addition, we outsource a portion of our research and development activities to certain third-party partners with development centers located in different countries, particularly Ukraine and India.
Our international operations, international operations of our resellers, contract manufacturers and outsourcing partners, and our efforts to maintain and increase revenue in international markets are subject to a number of risks, which are generally greater with respect to emerging market countries, including the following:
•growth and stability of the economy in one or more international regions, including regional economic impacts of the COVID-19 pandemic;
•fluctuations in currency exchange rates;
•changes in foreign government regulations and telecommunications standards;
•import and export license requirements, tariffs, taxes, economic sanctions, contractual limitations and other trade barriers;
•our significant reliance on resellers and others to purchase and resell our products and solutions, particularly in emerging market countries;
•availability of credit, particularly in emerging market countries;
•longer collection periods and greater difficulty in enforcing contracts and collecting accounts receivable, especially from smaller customers and resellers, particularly in emerging market countries;
29

Table of Contents
•compliance with the U.S. Foreign Corrupt Practices Act (the “FCPA”), the U.K. Bribery Act and/or similar anti-corruption and anti-bribery laws, particularly in emerging market countries;
•the burden of complying with a wide variety of foreign laws, treaties and technical standards;
•fulfilling “country of origin” requirements for our products for certain customers;
•difficulty in staffing and managing foreign operations;
•business and operational disruptions or delays caused by political, social and/or economic instability and unrest (e.g., Ukraine), including risks related to terrorist activity, particularly in emerging market countries;
•changes in economic policies by foreign governments, including the imposition and potential continued expansion of economic sanctions by the United States and the European Union on the Russian Federation;
•changes in diplomatic and trade relationships, including the imposition of new trade restrictions, trade protection measures, import or export requirements, trade embargoes and other trade barriers, including those between the United States and China;
•any negative economic impacts resulting from the political environment in the United States or the United Kingdoms’ exit from the European Union; and
•business and economic disruptions and delays caused by outbreaks of disease, epidemics and potential pandemics, such as the COVID-19 pandemic, which has led and may continue to lead to trade shows and in-person meetings being canceled or delayed and employees working remotely, and which has impacted our supply chain and may continue to impact our supply chain or general business in other manners.
We have certain international customers who are billed in their local currency, primarily the Euro, British pound and Japanese yen, which subjects us to foreign currency risk. In addition, a portion of our operating expenses relating to the cost of certain international employees, are denominated in foreign currencies, primarily the Euro, Israeli shekel, British pound, Singapore dollar, Chinese yuan and Indian rupee. Although we do hedge against the Euro, British pound, Israeli shekel and Japanese yen, gains and losses on the conversion to U.S. dollars of accounts receivable, accounts payable and other monetary assets and liabilities arising from international operations may contribute to fluctuations in our operating results. Furthermore, payment cycles for international customers are typically longer than those for customers in the United States. Unpredictable payment cycles could cause us to fail to meet or exceed the expectations of security analysts and investors for any given period.
Most of our international revenue is denominated in U.S. dollars, and fluctuations in currency exchange rates could cause our products to become relatively more expensive to customers in a particular country or region, leading to a reduction in revenue or profitability from sales in that country or region. The potential negative impact of a strong U.S. dollar on our business may be exacerbated by the significant devaluation of a number of foreign currencies. Also, if the U.S. dollar were to weaken against many foreign currencies, there can be no assurance that a weaker dollar would lead to growth in customer spending in foreign markets.
Our operations outside the United States also require us to comply with a number of U.S. and international regulations that prohibit improper payments or offers of payments to foreign governments and their officials and political parties for corrupt purposes. For example, our operations in countries outside the United States are subject to the FCPA and similar laws, including the U.K. Bribery Act. Our activities in certain emerging countries create the risk of unauthorized payments or offers of payments by one of our employees, consultants, sales agents or channel partners that could be in violation of various anti-corruption laws, even though these parties may not be under our control. Under the FCPA and U.K. Bribery Act, companies may be held liable for the corrupt actions taken by their directors, officers, employees, channel partners, sales agents, consultants, or other strategic or local partners or representatives. We have internal control policies and procedures with respect to FCPA compliance, have implemented FCPA training and compliance programs for our employees, and include in our agreements with resellers a requirement that those parties comply with the FCPA. However, we cannot provide assurances that our policies, procedures and programs will prevent violations of the FCPA or similar laws by our employees or agents, particularly in emerging market countries, and as we expand our international operations. Any such violation, even if prohibited by our policies, could result in criminal or civil sanctions against us.
The effect of one or more of these international risks could have a material and adverse effect on our business, financial condition, operating results and cash flows.

Risks Related to Ownership of Our Common Stock
Some anti-takeover provisions contained in our certificate of incorporation and bylaws, as well as provisions of Delaware law, could impair a takeover attempt.
We have provisions in our certificate of incorporation and bylaws that could have the effect of rendering more difficult or discouraging an acquisition deemed undesirable by our Board. These include provisions:
•authorizing blank check preferred stock, which could be issued with voting, liquidation, dividend and other rights superior to our common stock;
•limiting the liability of, and providing indemnification to, our directors and officers;
•limiting the ability of our stockholders to call, and bring business before, special meetings;
•requiring advance notice of stockholder proposals for business to be conducted at meetings of our stockholders and for nominations of candidates for election to our Board;
•controlling the procedures for conducting and scheduling of Board and stockholder meetings; and
•providing our Board with the express power to postpone previously scheduled annual meetings and to cancel previously scheduled special meetings.
These provisions could delay hostile takeovers, changes in control of the Company or changes in our management. As a Delaware corporation, we are also subject to provisions of Delaware law, including Section 203 of the Delaware General Corporation law, which prevents some stockholders holding more than 15% of our outstanding common stock from engaging in certain business combinations without approval of the holders of substantially all of our outstanding common stock. Any provision of our certificate of incorporation or bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock.
Our common stock price may be extremely volatile, and the value of an investment in our stock may decline.
Our common stock price has been highly volatile. We expect that this volatility will continue in the future due to factors such as:
•general market and economic conditions, including market volatility due to the COVID-19 pandemic;
•actual or anticipated variations in operating results;
•increases or decreases in the general stock market or to the stock prices of technology companies;
•announcements of technological innovations, new products or new services by us or by our competitors or customers;
•changes in financial estimates or recommendations by stock market analysts regarding us or our competitors;
•announcements by us or our competitors of significant acquisitions, dispositions, strategic partnerships, joint ventures or capital commitments;
•announcements by our customers regarding end user market conditions and the status of existing and future infrastructure network deployments;
•additions or departures of key personnel; and
•future equity or debt offerings or our announcements of these offerings.
In addition, in recent years, the stock market in general, and The NASDAQ Global Select Market and the securities of technology companies in particular, have experienced extreme price and volume fluctuations. These fluctuations have often been unrelated or disproportionate to the operating performance of individual companies. These broad market fluctuations have in the past, and may in the future, materially and adversely affect our stock price, regardless of our operating results. In these circumstances, investors may be unable to sell their shares of our common stock at or above their purchase price over the short term, or at all.

We cannot guarantee that our stock repurchase program will be fully implemented or that it will enhance long-term stockholder value.
In February 2022, our Board of Directors approved a stock repurchase program for the repurchase of up to $100 million of the outstanding shares of our common stock. The repurchase program expires in February 2025 and we are not obligated to repurchase a specified number or dollar value of shares. Share repurchases will be made from time to time in open market purchases and 10b5-1 trading plans, as permitted by securities laws and other legal requirements. Any share repurchases remain subject to the circumstances in place at that time, including prevailing market prices. As a result, there can be no guarantee around the timing or volume of our share repurchases. The stock repurchase program could affect the price of our common stock, increase volatility and diminish our cash reserves. Our repurchase program may be suspended or terminated at any time and, even if fully implemented, may not enhance long-term stockholder value.
Our stock price may decline if additional shares are sold in the market or if analysts drop coverage of or downgrade our stock.
Future sales of substantial amounts of shares of our common stock by our existing stockholders in the public market, or the perception that these sales could occur, may cause the market price of our common stock to decline. In addition, we issue additional shares upon exercise of stock options, including under our 2002 Employee Stock Purchase Plan, and in connection with grants of restricted stock units on an ongoing basis. To the extent we do not elect to pay solely cash upon conversion of the Notes, we will also be required to issue additional shares of common stock upon conversion. Increased sales of our common stock in the market after exercise of outstanding stock options or grants of restricted stock units could exert downward pressure on our stock price. These sales also might make it more difficult for us to sell equity or equity-related securities in the future at a time and price we deem appropriate.
The trading market for our common stock relies in part on the availability of research and reports that third-party industry or securities analysts publish about us and our business. If we do not maintain adequate research coverage or if one or more of the analysts who do cover us downgrade our stock or publishes inaccurate or unfavorable research about our business, our stock price may decline. If one or more of these analysts cease coverage of us or fails to publish reports on us regularly, we could lose visibility in the market, which in turn could cause the liquidity of our stock and our stock price to decline.

Item 1B. | UNRESOLVED STAFF COMMENTS

None.

Item 2. | PROPERTIES

All of our facilities are leased, including our principal operations and corporate headquarters in San Jose, California. We have research and development centers in the United States, France, Israel and Hong Kong. We have sales and service offices primarily in the United States and various locations in Europe and Asia. Our leases, which expire at various dates throu gh September 2032, are for an aggregate of approximately 301,718 s quare feet of space. We have two business segments: Video and Cable Access. Because of the interrelation of these segments, a majority of these segments use substantially all of the properties, at least in part, and we retain the flexibility to use each of the properties in whole or in part for each of the segments. We believe that the facilities that we currently occupy are adequate for our current needs and that suitable additional space will be available, as needed, to accommodate the presently foreseeable expansion of our operations.

Item 3. | LEGAL PROCEEDINGS

From time to time, we are involved in lawsuits as well as subject to various legal proceedings, claims, threats of litigation, and investigations in the ordinary course of business, including claims of alleged infringement of third-party patents and other intellectual property rights, commercial, employment, and other matters. While certain matters to which we are a party may specify the damages claimed, such claims may not represent reasonably possible losses. Given the inherent uncertainties of litigation, the ultimate outcome of these matters cannot be predicted at this time, nor can the amount of possible loss or range of loss, if any, be reasonably estimated.
An unfavorable outcome on any litigation matters could require us to pay substantial damages, or, in connection with any intellectual property infringement claims, could require us to pay ongoing royalty payments or could prevent us from selling certain of our products. As a result, a settlement of, or an unfavorable outcome on, any of the matters referenced above or other litigation matters could have a material adverse effect on our business, operating results, financial position and cash flows.
Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. From time to time, third parties have asserted, and may in the future assert, exclusive patent, copyright, trademark and other intellectual property rights against us or our customers. Such assertions arise in the normal course of our operations. The resolution of any such assertions and claims cannot be predicted with certainty.

Item 7. | MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the consolidated financial statements and the related notes. The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include, but are not limited to, those discussed below and those listed under Item 1A, Risks Factors. For discussion of comparison of our results of operations and cash flows for the fiscal years ended December 31, 2020 and 2019, refer to Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the SEC on March 2,2021.
Business Overview
We are a leading global provider of (i) versatile and high performance video delivery software, products, system solutions and services that enable our customers to efficiently create, prepare, store, playout and deliver a full range of high-quality broadcast and streaming video services to consumer devices, including televisions, personal computers, laptops, tablets and smart phones and (ii) cable access solutions that enable cable operators to more efficiently and effectively deploy high-speed internet, for data, voice and video services to consumers’ homes.
We classify our total revenue in two categories, “Appliance and integration” and “SaaS and service.” The “Appliance and integration” revenue category includes hardware, licenses and professional services and is reflective of non-recurring revenue, while the “SaaS and service” category includes usage fees for our SaaS platform and support service revenue from our appliance-based customers and reflects our recurring revenue stream.
We conduct business in three geographic regions - the Americas, EMEA and APAC - and operate in two segments, Video and Cable Access. Our Video business sells video processing, production and playout solutions, and services worldwide to cable operators and satellite and telecommunications (“telco”) Pay-TV service providers, which we refer to collectively as “service providers,” as well as to broadcast and media companies, including streaming media companies. Our Video business infrastructure solutions are delivered either through shipment of our products, software licenses or as SaaS subscriptions. Our Cable Access business sells cable access solutions and related services, including our CableOS software-based cable access solution, primarily to cable operators globally.
Historically, our revenue has been dependent upon spending in the cable, satellite, telco, broadcast and media industries, including streaming media. Our customers’ spending patterns are dependent on a variety of factors, including but not limited to: economic conditions in the United States and international markets, including the impacts of the COVID-19 pandemic; access to financing; annual budget cycles of each of the industries we serve; impact of industry consolidations; and customers suspending or reducing spending in anticipation of new products or new standards, new industry trends and/or technology shifts. If our product portfolio and product development plans do not position us well to capture an increased portion of the spending in the markets in which we compete, our revenue may decline. As we attempt to further diversify our customer base in these markets, we may need to continue to build alliances with other equipment manufacturers, cloud service providers, content providers, resellers and system integrators, managed services providers and software developers; adapt our products for new applications; take orders at prices resulting in lower margins; and build internal expertise to handle the particular operational, payment, financing and/or contractual demands of our customers, which could result in higher operating costs for us.
The worldwide spread of COVID-19 has impacted our business, operations and financial performance. In our Cable Access segment, COVID-19 led to delays in certain deployments and new engagements with some cable operators, which generally occurred in the first half of fiscal 2020 when widespread public health responses were initially implemented, including travel bans and restrictions, social distancing requirements, and shelter-in-place orders. Similarly, in our Video segment, sales of video appliances and services fell during the first several months of the pandemic as transactions or shipments were delayed and we were unable to complete certain field deployment projects as customer facilities closed in the first half of 2020. In the second half of fiscal 2020, and throughout fiscal 2021, we experienced a rebound and increases in sales activities, transactions and deployments in both business segments, in part due to the loosening of certain COVID-19 restrictions, and customer adaptation to such restrictions. We expect that the COVID-19 pandemic will continue to have an impact on our results of operations.

Table of Contents
The extent to which our operations will be impacted by the pandemic will depend largely on future developments, which are highly uncertain and cannot be accurately predicted, including pandemic-related supply chain disruptions and the pricing and availability of certain materials and components, increased costs relating to securing timely and sufficient supply of key product components, new waves of infection in the countries and regions of the world in which we operate or conduct business, the impact of global vaccination efforts, and actions and policies of governments and businesses in response to future phases of the pandemic. As such, given the uncertainty around the duration and severity of the impact on market conditions and the business environment, we cannot reasonably estimate the full impacts of COVID-19 on our future results of operations. See “Risk Factors” in Item 1A of Part I of this Annual Report on Form 10-K for additional information.
We believe a material and growing portion of the opportunities for our Video business are linked to the industry and our customers (i) continuing to adopt streaming technologies to capture, process and deliver video content to consumers and, increasingly, utilizing public cloud solutions like our VOS SaaS platform to do so; (ii) transforming existing broadcast infrastructure workflows into more flexible, efficient and cost-effective operations running in public clouds; and (iii) for those customers maintaining on-premise video delivery infrastructure, continuing to upgrade and replace aging equipment with next-generation software-based appliances that significantly reduce operational complexity. Our Video business strategy is focused on continuing to develop and deliver products, solutions and services to enable and support these trends.
Our Cable Access strategy is focused on continuing to develop and deliver software-based cable access technologies, which we refer to as our CableOS solutions, to our cable operator customers. We believe our CableOS software-based cable access solutions are superior to hardware-based systems and deliver unprecedented scalability, agility and cost savings for our customers. Our CableOS solutions, which can be deployed based on a centralized, DAA or hybrid architecture, enable our customers to migrate to multi-gigabit broadband capacity and the fast deployment of DOCSIS 3.1 and/or FTTH data, video and voice services. We believe our CableOS solutions resolve space and power constraints in cable operator facilities, eliminate dependence on hardware upgrade cycles and significantly reduce total cost of ownership, and are helping us become a major player in the cable access market. In the meantime, we believe our Cable Access segment will continue to gain momentum in the marketplace as our customers adopt and deploy our virtualized DOCSIS 3.1 CMTS and FTHH solutions and distributed access architectures. We continue to make progress in the development of our CableOS solutions and in the growth of our CableOS business, with expanded commercial deployments, field trials, and customer engagements.
Critical Accounting Estimates
The preparation of consolidated financial statements and related disclosures, which are prepared in accordance with GAAP, requires Harmonic to make judgments, assumptions and estimates that affect the reported amounts of assets and liabilities, the disclosure of contingencies and the reported amounts of revenue and expenses in the financial statements and accompanying notes. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions we believe to be reasonable under the circumstances. Material differences may result in the amount and timing of revenue and expenses if different judgments or different estimates were made. Refer to Note 2 of the Notes to our Consolidated Financial Statements for details of our accounting estimates.
We believe that the following critical accounting estimates involve a greater degree of judgement or complexity than our other accounting estimates. Accordingly, the critical accounting estimates that we believe have the most significant impact on Harmonic’s financial statements are set forth below:
•Revenue recognition;
•Valuation of inventories;
•Impairment of goodwill or long-lived assets; and
•Accounting for income taxes.
Revenue Recognition
We recognize revenue from contracts with customers using the following five steps:
a) Identify the contract(s) with a customer;
b) Identify the performance obligations in the contract;
c) Determine the transaction price;
d) Allocate the transaction price to the performance obligations in the contract; and
e) Recognize revenue when (or as) we satisfy a performance obligation.
Refer to Note 3, “Revenue,” of the Notes to our Consolidated Financial Statements for additional information about our revenue recognition policies, including critical judgments and estimates associated with our revenue recognition.

Table of Contents
Valuation of Inventories
We state inventories at the lower-of-cost (determined on first-in, first-out basis) or net realizable value. We write down the cost of excess or obsolete inventory to net realizable value based on future demand forecasts and historical consumption. If there were to be a sudden and significant decrease in demand for our products, or if there were a higher incidence of inventory obsolescence because of rapidly changing technology and customer requirements, we could be required to record additional charges for excess and obsolete inventory and our gross margin could be adversely affected. Inventory management is of critical importance in order to balance the need to maintain strategic inventory levels to ensure competitive lead times against the risk of inventory obsolescence because of rapidly changing technology and customer requirements.
Impairment of Goodwill and Long-lived Assets
In evaluating goodwill for impairment, we first assess qualitative factors such as the magnitude of the excess fair value over carrying value from the prior period’s impairment testing, other reporting unit specific operating results as well as new events and circumstances impacting the operations at the reporting unit level. If the result of a qualitative test indicates a potential for impairment of a reporting unit, a quantitative impairment test is performed to determine the fair value of the reporting unit and compare it with its carrying value. We determine the fair value of our reporting units using both income and market valuation approaches.
We evaluate the recoverability of intangible assets and other long-lived assets when indicators of impairment are present. When impairment indicators are present, we evaluate the recoverability of intangible assets and other long-lived assets on the basis of undiscounted cash flows expected to result from the use of each asset group and its eventual disposition. If the undiscounted expected future cash flows are less than the carrying amount of the asset, an impairment loss is recognized in order to write down the carrying value of the asset to its estimated fair value.
In the current year our annual qualitative assessment did not indicate that a more detailed quantitative analysis was necessary.
Accounting for Income Taxes
In preparing our consolidated financial statements, we estimate our income taxes for each of the jurisdictions in which we operate. This involves estimating our actual current tax expense and assessing temporary differences resulting from differing treatment of items, such as reserves and accruals, for tax and accounting purposes. These temporary differences result in deferred tax assets and liabilities, which are included within our Consolidated Balance Sheets. We maintain valuation allowances for deferred tax assets when it is likely that all or a portion of a deferred tax asset will not be realized. In determining whether a valuation allowance is warranted, we take into account such factors as prior earnings history, expected future earnings, unsettled circumstances that, if unfavorably resolved, would adversely affect the utilization of a deferred tax asset.
We are subject to examination of our income tax returns by various tax authorities on a periodic basis. We regularly assess the likelihood of adverse outcomes resulting from such examinations to determine the adequacy of our provision for income taxes. We apply the provisions of the applicable accounting guidance regarding accounting for uncertainty in income taxes, which requires application of a more-likely-than-not threshold to the recog nition and derecognition of uncertain tax positions. If the recognition threshold is met, the applicable accounting guidance permits us to recognize a tax benefit measured at the largest amount of such tax benefit that, in our judgment, is more than fifty percent l ikely to be realized upon settlement. It further requires that a change in judgment related to the expected ultimate resolution of uncertain tax positions be recognized in earnings in the period in which such determination is made.
We file annual income tax returns in multiple taxing jurisdictions around the world. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, we believe that our reserves for income taxes reflect the most likely outcome. We adjust these reserves, as well as the related interest and penalties, in light of changing facts and circumstances. If our estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when we determine the liabilities are no longer necessary. Any changes in estimate, or settlement of any particular position, could have a material impact on our operating results, financial condition and cash flows.

The amortization of intangibles expense decreased in 2021, as compared to 2020, as intangible assets were fully amortized during the first quarter of fiscal 2021.
Restructuring and Related Charges
We have implemented several restructuring plans in the past few years. The goal of these plans is to bring operational expenses to appropriate levels relative to our net revenues, while simultaneously implementing extensive company-wide expense control programs. We account for our restructuring plans under the authoritative guidance for exit or disposal activities. The restructuring and related charges are included in “Cost of revenue” and “Operating expenses-restructuring and related charges” in the Consolidated Statements of Operations.

Other income (expense), net is primarily comprised of foreign exchange gains and losses on cash, accounts receivable and intercompany balances denominated in currencies other than the functional currency of the reporting entity. Our foreign currency exposure is primarily driven by the fluctuations in the foreign currency exchanges rates of the Euro, British pound, Japanese yen and Israeli shekel. The change in other income (expense), net in 2021, as compared to 2020, was primarily due to the exchange rate fluctuation between Euro and the U.S. dollar in 2021.

The change in provision for (benefit from) income taxes in 2021, as compared to 2020, was primarily due to the release of the valuation allowance on deferred tax assets in certain foreign jurisdictions of $8.6 million in recognition of their improved historical earnings and increasing future projected earnings.

(1) Together with amortization of intangibles and stock-based compensation, we do not allocate restructuring and related charges, and certain other non-recurring charges, to the operating income for each segment because our management does not include this information in the measurement of the performance of the operating segments.
Video
Our Video segment net revenue increased in 2021, as compared to 2020, primarily due to an increase of $40.9 million in Video appliance and integration revenue, reflecting the impact from the COVID-19 pandemic on 2020 results, and an increase of $5.1 million in Video SaaS and service revenue, reflecting increasing usage from existing customers and activation of new SaaS customers. Video segment operating margin increased in 2021, as compared to 2020, primarily due to the increase in revenue and related gross profit, partially offset by higher employee compensation costs as a result of headcount increases.
Cable Access
Our Cable Access segment net revenue increased in 2021, as compared to 2020, primarily due to the increased penetration of our existing CableOS customers and addition of new CableOS customer deployments in 2021. Cable Access segment operating margin decreased in 2021, as compared to 2020, primarily due to change in product mix, increased costs of supply chain related to increased pricing, freight and shipping, and higher employee compensation costs as a result of headcount increases, partially offset by revenue growth.

Liquidity and Capital Resources
We expect to continue to generate net positive operating cash flow as we have done in the last three fiscal years. The cash we generate from our operations enables us to fund ongoing operations, our research and development projects for new products and technologies, and other business activities. We continually evaluate our cash needs and may decide it is best to raise additional capital or seek alternative financing sources to fund our operations, the growth of our business, to take advantage of unanticipated strategic opportunities, or to strengthen our financial position, including through drawdowns on existing or new debt facilities or new financing (debt and equity) funds. In the future, we may enter into other arrangements for potential investments in, or acquisitions of, complementary businesses, services or technologies, which could require us to seek additional equity or debt financing. Additional funds may not be available on terms favorable to us or at all. Conversely, we may also from time to time determine that it is in our best interests to voluntarily repay certain indebtedness early. We believe that our current sources of funds will provide us with adequate liquidity during the 12-month period following December 31, 2021, as well as in the long-term.
Material Cash Requirements
Our principal uses of cash will include repayments of debt and related interest, purchases of inventory, stock repurchases, payments for payroll, restructuring expenses, and other operating expenses related to the development and marketing of our products, purchases of property and equipment, facility leases, and other contractual obligations for the foreseeable future.
As of December 31, 2021, we had outstanding $171.2 million in aggregate principal amount of indebtedness, consisting of our 2022 Notes, 2024 Notes, and other debts, of which $42.7 million is scheduled to become due in the 12-month period following December 31, 2021. As of December 31, 2021, our total minimum lease payments are $45.5 million, of which $7.8 million is due in the 12-month period following December 31, 2021. For details regarding our indebtedness and lease obligations, refer to Note 11, “Convertible Notes and Other Debts”, and Note 4, “Leases”, respectively, of the Notes to our Consolidated Financial Statements included elsewhere in this Annual Report on Form 10-K.
On February 3, 2022, the Board of Directors authorized us to repurchase, from time to time, up to $100 million of our outstanding shares of common stock through February 2025, at such time and such prices as management may decide. The program does not obligate us to repurchase any specific number of shares and may be discontinued at any time.
Sources and Conditions of Liquidity
Our sources to fund our material cash requirements are predominantly from our sales of our products and services and, when applicable, proceeds from debt facilities and debt and equity offerings.
As of December 31, 2021, our principal sources of liquidity consisted of cash and cash equivalents of $133.4 million, net accounts receivable of $88.5 million, and our $25.0 million revolving credit facility with JPMorgan Chase Bank, N.A., described in further detail below.
On March 27, 2020, the “Coronavirus Aid, Relief, and Economic Security” Act that was signed into law in the United States. Under provisions of this law, we deferred remittance of $1.7 million in employer’s share of payroll taxes incurred from March 27, 2020 to December 31, 2020. During 2021, $0.8 million of the total deferred payroll taxes has been paid, and the remaining deferred amount will be paid before December 31, 2022.

On December 19, 2019, we entered into a Credit Agreement (the “Credit Agreement”) with JPMorgan Chase Bank, N.A., as lender, and Harmonic International GmbH, as co-borrower. The Credit Agreement provides for a secured revolving loan facility in an aggregate principal amount of up to $25.0 million, which may also be used for the issuance of letters of credit. Under the terms of the Credit Agreement, the principal amount of outstanding loans, plus the face amount of any outstanding letters of credit, at any time cannot exceed an amount equal to the lesser of (i) $25.0 million and (ii) the sum of 85% of our eligible receivables and 50% of our eligible inventory. During fiscal 2020, we amended the Credit Agreement to extend the maturity date to October 30, 2022 and amend the interest rates for the revolving loans. As amended, the revolving loans bear interest, at our election, at a floating rate per annum equal to either (1) 2.00% plus the greater of (i) 1 month LIBOR on any day plus 2.50% and (ii) the prime rate as reported in the Wall Street Journal from time to time or (2) 3.00% plus LIBOR for an interest period of one, two or three months. Interest on the revolving loans is payable monthly in arrears, in the case of prime rate loans, and at the end of the applicable interest period, in the case of LIBOR loans. We are also obligated to pay other customary closing fees, commitment fees and letter of credit fees for a credit facility of this size and type. Our obligations are required to be guaranteed by certain material domestic subsidiaries, and all such obligations, including the guarantees, are secured by substantially all of the assets of the Company and such guarantors and certain assets of Harmonic International GmbH. The Credit Agreement contains customary affirmative and negative covenants, including covenants limiting our ability to, among other things, incur debt, grant liens, undergo certain fundamental changes, make investments, make certain restricted payments, dispose of assets, enter into transactions with affiliates, and enter into burdensome agreements, in each case, subject to limitations and exceptions set forth in the Credit Agreement. We are also required to maintain compliance with an adjusted quick ratio, a minimum EBITDA covenant (tested quarterly) and a minimum liquidity covenant, in each case, determined in accordance with the terms of the Credit Agreement. There were no revolving borrowings under the Credit Agreement from the closing of the Credit Agreement through December 31, 2021. As of December 31, 2021, we were in compliance with the covenants under the Credit Agreement.
Our cash and cash equivalents of $133.4 million as of December 31, 2021 consisted of bank deposits held throughout the world, of which $91.8 million was held outside of the United States. At present, such foreign funds are considered to be indefinitely reinvested in foreign countries to the extent of indefinitely reinvested foreign earnings. In the event funds from foreign operations are needed to fund cash needs in the United States and if U.S. taxes have not already been previously accrued, we may be required to accrue and pay additional U.S. and foreign withholding taxes in order to repatriate these funds.
Summary of Cash Flows

| Year ended December 31,
(in thousands) | 2021 |  | 2020 |  | 2019
Net cash provided by operating activities | $ | 41,017 |  |  | $ | 39,163 |  |  | $ | 31,295 |
Net cash used in investing activities | (12,975) |  |  | (32,205) |  |  | (10,328) |

Effect of exchange rate changes on cash, cash equivalents and restricted cash | (1,195) |  |  | 738 |  |  | (203) |
Net increase in cash, cash equivalents and restricted cash | $ | 34,786 |  |  | $ | 5,587 |  |  | $ | 27,069 |

Operating Activities
Net cash provided by operating activities increased $1.9 million in 2021, as compared to 2020, primarily due to net income in 2021, as compared to net loss in 2020, offset by cash used for working capital in 2021.
We expect that cash provided by or used in operating activities may fluctuate in future periods as a result of a number of factors, including the impact of COVID-19 on demand for our offerings, fluctuations in our operating results, shipment linearity, accounts receivable collections performance, inventory and supply chain management, and the timing and amount of compensation and other payments.
Investing Activities
Net cash used in investing activities decreased $19.2 million in 2021, as compared to 2020, mainly due to purchases of assets relating to the leasehold improvements of the Company’s new headquarters completed in fiscal 2020.
Financing Activities
Net cash provided by (used in) financing activities increased $10.0 million in 2021 compared to 2020, primarily due to the repayment of the $8.0 million remaining principal of the 2020 Notes in December 2020.

Item 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Foreign Currency Exchange Risk
We market and sell our products and services through our direct sales force and indirect channel partners in North America, EMEA, APAC and Latin America. Accordingly, we are subject to exposure from adverse movements in foreign currency exchange rates, primarily the Euro, British pound, Israeli shekel and Japanese yen. Our U.S. dollar functional subsidiaries account for approximately 96%, 95% and 94% of our consolidated net revenues in 2021, 2020 and 2019, respectively. We recorded net billings denominated in foreign currencies of approximately 18%, 22% and 16% of total company billings in 2021, 2020 and 2019, respectively. In addition, a portion of our operating expenses, primarily the cost of personnel to deliver technical support on our products and professional services, sales and sales support and research and development, are denominated in foreign currencies, primarily the Euro, Israeli shekel and British pound.
We use derivative instruments, primarily forward contracts, to manage exposures to foreign currency exchange rates and we do not enter into foreign currency forward contracts for trading purposes.
Derivatives Not Designated as Hedging Instruments (Balance Sheet Hedges)
We enter into forward currency contracts to hedge foreign currency denominated monetary assets and liabilities. These derivative instruments are marked to market through earnings every period and mature generally within three months. Changes in the fair value of these foreign currency forward contracts are recognized in “Other income (expense), net” in the Consolidated Statements of Operations, and are largely offset by the changes in the fair value of the assets or liabilities being hedged.
The U.S. dollar equivalents of all outstanding notional amounts of foreign currency forward contracts are summarized as follows:

|  | December 31,
(in thousands) |  | 2021 |  | 2020
Derivatives not designated as hedging instruments: |  |  |  |
Purchase |  | $ | 2,926 |  |  | $ | 11,426 |
Sell |  | $ | 5,175 |  |  | $ | — |

Interest Rate Risk
Our exposure to market risk for changes in interest rates relates primarily to our outstanding debt arrangements with variable rate interests as well as our borrowings under the Credit Agreement.
On December 19, 2019, we entered into a Credit Agreement with JPMorgan Chase Bank, N.A., and Harmonic International GmbH, as co-borrower. The Credit Agreement provides for a secured revolving loan facility in an aggregate principal amount of up to $25.0 million, based on a borrowing base of eligible accounts receivable and inventory. During fiscal 2020, we amended the Credit Agreement to extend the Credit Agreement maturity date to October 30, 2022 and amend the interest rates for the revolving loans. As amended, the revolving loans bear interest, at our election, at a floating rate per annum equal to either (1) 1.25% plus the greater of (i) 1 month LIBOR on any day plus 2.50% and (ii) the prime rate as reported in the Wall Street Journal from time to time or (2) 2.25% plus LIBOR for an interest period of one, two or three months. Interest on the revolving loans is payable monthly in arrears, in the case of prime rate loans, and at the end of the applicable interest period, in the case of LIBOR. We had no revolving borrowings under the Credit Agreement from the closing of the Credit Agreement through December 31, 2021.
For our French entity, the aggregate debt balance at December 31, 2021 was $18.0 million, which are financed by French government agencies. These debt instruments have maturities ranging from one to five years; expiring from 2022 through 2026. These loans are tied to the 1-month EURIBOR rate plus spread. Refer to Note 11, “Convertible Notes and Other Debts,” of the Notes to our Consolidated Financial Statements for additional information. As of December 31, 2021, a hypothetical 1.0% increase in interest rates on our debts subject to variable interest rate fluctuations would increase our interest expense by approximately $0.2 million annually.
As of December 31, 2021, we had $37.7 million aggregate principal amount of the 2022 Notes outstanding, which have a fixed 4.375% coupon rate and $115.5 million aggregate principal of the 2024 Notes outstanding, which have a fixed 2.00% coupon rate. Additionally, during fiscal 2020, we received a loan from Société Générale S.A. in France which bears an effective interest rate of 0.51% per annum, in connection with relief loan programs related to the COVID-19 pandemic. As of December 31, 2021, the outstanding balance of this loan was $5.7 million.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Stockholders and the Board of Directors of Harmonic, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheet of Harmonic, Inc. (the Company) as of December 31, 2021, the related consolidated statements of operations, comprehensive income, stockholders' equity and cash flows for the year ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021, and the results of its operations and its cash flows for the year ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 28, 2022 expressed an unqualified opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Inventory Valuation

Description of the Matter | The Company’s net inventory totaled $71.2 million as of December 31, 2021. As explained in “Note 2: Accounting Policies” within the consolidated financial statements, inventory is stated at the lower of cost (determined on a first-in, first-out basis) or net realizable value. The Company establishes a provision for excess and obsolete inventory to reduce such inventory to its estimated net realizable value. Auditing management’s estimates for excess and obsolete inventory involved auditor judgment due to the assessment of management’s estimates of whether a provision for excess and obsolete inventory is required. The measurement of any excess of cost over net realizable value is judgmental and is impacted by a number of factors that are affected by general economic and market conditions outside the Company’s control. Specifically, excess and obsolete inventory calculations are sensitive to significant assumptions that relate to future customer demand for the Company’s products.
How We Addressed the Matter in Our Audit | We obtained an understanding, evaluated the design and tested the operating effectiveness of internal controls over the Company’s excess and obsolete inventory reserve process. This included controls over management’s determination of inventory valuation, including the evaluation of future demand of the Company’s products and the completeness and accuracy of the data underlying the excess and obsolete inventory valuation. We performed audit procedures that included, among others, assessing the Company’s methodology over the computation of the provision for excess and obsolete inventory, testing the significant assumptions and the underlying inputs used by the Company in its analysis including historical sales trends, expectations regarding future demand, changes in the Company’s business, customer base, product life cycles and other relevant factors. We evaluated current inventory levels compared to future demand and historical sales.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Stockholders and the Board of Directors of Harmonic, Inc.
Opinion on Internal Control Over Financial Reporting
We have audited Harmonic, Inc.’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Harmonic, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2021, the related consolidated statements of operations, comprehensive income, stockholders' equity and cash flows for the year ended December 31, 2021, and the related notes and our report dated February 28, 2022 expressed an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

We also have audited the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020 in conformity with 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 December 31, 2020, based on criteria established in Internal Control-Integrated Framework (2013) issued by COSO.
Change in Accounting Principle
As discussed in Note 2 to the consolidated financial statements, the Company changed its method of accounting for leases in 2019 due to the adoption of Accounting Standards Update (ASU) No. 2016-02, Leases (Topic 842).
Basis for Opinion
The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control 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 financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition — Refer to Note 2 and 3 to the Consolidated Financial Statements

Critical Audit Matter Description
The Company recognizes revenue upon transfer of control of promised products and services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company’s contract may contain one or more performance obligations, including hardware, software, professional services and support and maintenance.
Significant judgment is exercised by the Company in determining revenue recognition for these customer agreements, and includes the following:
•Determination of whether products and services are considered distinct performance obligations that should be accounted for separately versus together
•Determination of stand-alone selling prices for each distinct performance obligation and for products and services that are not sold separately
•Determination of the pattern of delivery (i.e., timing of when revenue is recognized) for each distinct performance obligation
•Estimation of variable consideration when determining the amount of revenue to recognize (e.g., customer credits, incentives, and in certain instances, determination and estimation of material rights)
Given these factors, the related audit effort in evaluating management’s judgments in determining revenue recognition for these customer agreements was extensive and required a high degree of auditor judgment.
How the Critical Audit Matter Was Addressed in the Audit
Our principal audit procedures related to the Company’s revenue recognition for these customer agreements included the following:
•We tested the effectiveness of internal controls related to the identification of distinct performance obligations, determination of the timing of revenue recognition, and the estimation of variable consideration.
•We selected a sample of customer agreements and performed the following procedures:
◦Obtained and read contract source documents for each selection, including master agreements, and other documents that were part of the agreement to identify significant terms
◦Tested management’s identification of significant terms for completeness, including the identification of distinct performance obligations and variable consideration
◦Tested the mathematical accuracy of management’s calculations of revenue and the associated timing of recognizing the related revenue subject to any constraints in the consolidated financial statements
◦Assessed the terms in the customer agreement and evaluated the appropriateness of management’s application of their accounting policies, along with their use of estimates, in the determination of revenue recognition conclusions
•We evaluated the reasonableness of management’s estimate of stand-alone selling prices for products and services that are not sold separately.
•We evaluated the reasonableness and accuracy of management’s judgments and estimates used in accounting for discounts and credits for future purchases (“material rights”) which include estimating the stand-alone selling price of a material right. This included testing management’s estimate of calculating discounts offered to customers, assessing management’s probability of customer exercising the material right and verifying future sales forecast with the operations team.

Inventory Valuation— Refer to Note 2 to the Consolidated Financial Statements

Critical Audit Matter Description
The Company computes inventory cost on a first-in, first-out basis and applies judgment in determining forecast for products and the valuation of inventories. The Company assesses inventory at each reporting date in order to assert that it is recorded at net realizable value, giving consideration to, among other factors: whether the product is valued at the lower-of-cost or net realizable value; and the estimation of excess and obsolete inventory or that which is not of saleable quality. Most of the Company’s inventory provisions are based on the Company’s inventory levels and future product purchase commitments compared to assumptions about future demand and market conditions.
Significant judgment is exercised by the Company to determine inventory carrying value adjustments, specifically the provisions for excess or obsolete inventories, and includes:
•Developing assumptions such as forecasts of future sales quantities and the selling prices, which are sensitive to the competitiveness of product offerings, customer requirements, and product life cycles.
Given these factors and assumptions are forward-looking and could be affected by future economic and market conditions, the related audit effort to evaluate management’s inventory valuation adjustments was extensive and required a high degree of auditor judgment.
How the Critical Audit Matter Was Addressed in the Audit
Our principal audit procedures related to the Company’s inventory valuation methodology included the following:
•We tested the effectiveness of internal controls related to inventory carrying value adjustment determination process, including management’s assumptions related to future demand and market conditions.
•We selected a sample of inventory items and performed the following procedures:
◦Tested the mathematical accuracy of the Company’s inventory schedule by comparing the quantities and carrying value of on-hand inventories to related unit sales, both historical and forecasted
◦Assessed and tested the reasonableness of the significant assumptions (e.g. sales and marketing forecast, build plans, usage and open sales-order)
◦Inquired with the Operations team and evaluated the adequacy of management’s adjustments to sales forecasts by analyzing potential technological changes in line with product life cycles and/or identified alternative customer uses
◦Assessed whether there were any potential sources of contrary information, including historical forecast accuracy or history of significant revisions to previously recorded inventory valuation adjustments, and performed sensitivity analyses over significant assumptions to evaluate the changes in inventory valuation that would result from changes in the assumptions.

The Video business sells video processing and production and playout solutions and services worldwide to cable operators and satellite and telecommunications (“telco”) pay-TV service providers, which are collectively referred to as “service providers,” and to broadcast and media companies, including streaming media companies. The Video business infrastructure solutions are delivered either through shipment of our products, software licenses or as software-as-a-service (“SaaS”) subscriptions. The Cable Access business sells cable access solutions and related services, including our CableOS software-based cable access solution, primarily to cable operators globally.
NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
The accompanying consolidated financial statements of Harmonic include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company’s fiscal quarters are based on 13-week periods, except for the fourth quarter which ends on December 31.
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The Company’s reported financial positions or results of operations may be materially different under changed conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies. If estimates or assumptions differ from actual results, subsequent periods are adjusted to reflect more current information.
Reclassifications
Certain prior period balances have been reclassified to conform to the current year presentation. These reclassifications did not have a material impact on previously reported financial statements.
Cash and Cash Equivalents
All highly liquid investments with an original maturity of three months or less at the date of purchase are considered cash equivalents. The carrying amount of cash and cash equivalents approximates fair value because of the short maturity of those instruments.
Credit Risk and Major Customers/Supplier Concentration
Financial instruments which subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, and accounts receivable. Cash and cash equivalents are invested in short-term, highly liquid, investment-grade instruments, in accordance with the Company’s investment policy. The investment policy limits the amount of credit exposure to any one financial institution, commercial or governmental issuer.
The Company’s accounts receivable are derived from sales to worldwide cable, satellite, telco, and broadcast and media companies. The Company generally does not require collateral from its customers, and performs ongoing credit evaluations of its customers and provides for expected losses. The Company maintains an allowance for doubtful accounts based upon the expected collectability of its accounts receivable. One customer had a balance greater than 10% of the Company’s net accounts receivable balance as of December 31, 2021 and 2020. During the year ended December 31, 2021, 2020 and 2019, Comcast is the only customer accounted for more than 10% of the Company’s revenue.

Table of Contents
Certain of the components and subassemblies included in the Company’s products are obtained from a single source or a limited group of suppliers. Although the Company seeks to reduce dependence on those sole source and limited source suppliers, the partial or complete loss of certain of these sources could have at least a temporary adverse effect on the Company’s results of operations and damage customer relationships.
Revenue Recognition
The Company’s principal sources of revenue are from the sale of hardware, software, hardware and software maintenance contracts, and end-to-end solutions, encompassing design, manufacture, test, integration and installation of products. The Company also derives recurring revenue from subscriptions, which are comprised of subscription fees from customers utilizing the Company’s cloud-based video processing solutions.
Revenue from contracts with customers is recognized using the following five steps:
a) Identify the contract(s) with a customer;
b) Identify the performance obligations in the contract;
c) Determine the transaction price;
d) Allocate the transaction price to the performance obligations in the contract; and
e) Recognize revenue when (or as) the Company satisfies a performance obligation.
A contract contains a promise (or promises) to transfer goods or services to a customer. A performance obligation is a promise (or a group of promises) that is distinct. The transaction price is the amount of consideration a Company expects to be entitled to from a customer in exchange for providing the goods or services.
The unit of account for revenue recognition is a performance obligation. A contract may contain one or more performance obligations, including hardware, software, professional services and support and maintenance. Performance obligations are accounted for separately if they are distinct. A good or service is distinct if the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer, and the good or service is distinct in the context of the contract. Otherwise performance obligations will be combined with other promised goods or services until the Company identifies a bundle of goods or services that is distinct.
The transaction price is allocated to all the separate performance obligations in an arrangement. It reflects the amount of consideration to which the Company expects to be entitled to in exchange for transferring goods or services, which may include an estimate of variable consideration to the extent that it is probable of not being subject to significant reversals in the future based on the Company’s experience with similar arrangements. The transaction price also reflects the impact of the time value of money if there is a significant financing component present in an arrangement. The transaction price excludes amounts collected on behalf of third parties, such as sales taxes.
Revenue is recognized when the Company satisfies each performance obligation by transferring control of the promised goods or services to the customer. Goods or services can transfer at a point in time or over time depending on the nature of the arrangement.
Refer to Note 3, “Revenue,” for additional information.
Inventories
Inventories are stated at the lower of cost (determined on first-in, first-out basis) or net realizable value. The cost of inventories is comprised of material and manufacturing labor and overheads. The Company establishes provisions for excess and obsolete inventories to reduce such inventories to their estimated net realizable value after evaluation of historical sales, future demand and market conditions, expected product life cycles and current inventory levels. Such provisions are charged to cost of revenue in the Company’s Consolidated Statements of Operations.
Property and Equipment
Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Estimated useful lives are generally five years for furniture and fixtures, three years for software and four years for machinery and equipment. Depreciation for leasehold improvements are computed using the shorter of estimated useful lives or the terms of the related leases.
Long-Lived Assets including Purchased Intangible Assets
The Company reviews property and equipment, intangible assets and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset (or asset group) may not be recoverable.
56

Table of Contents
Recoverability is measured by comparing the carrying amount to the future undiscounted cash flows that the asset is expected to generate. If the asset is not recoverable, its carrying amount would be adjusted down to its fair value. For the years ended December 31, 2021, 2020 and 2019, there were no impairment charges for long-lived assets.
Goodwill
The Company assesses goodwill for impairment on an annual basis (in the fourth quarter), or more frequently if events or changes in circumstances indicate that it might be impaired, by comparing its carrying value to the reporting unit’s fair value. For the years ended December 31, 2021, 2020 and 2019, there were no impairment charges for goodwill.
Refer to Note 7, “Goodwill,” for additional information.
Leases
On January 1, 2019, the Company adopted ASC 842, Leases (“Topic 842”), using the modified retrospective method, applying Topic 842 to all leases existing at the date of initial application. The Company elected to use the effective date as the date of initial application. Consequently, prior period balances and disclosures have not been restated. The Company elected certain practical expedients, which among other things, allowed the Company to carry forward prior conclusions about lease identification and classification.
Under Topic 842, operating lease expense is generally recognized evenly over the term of the lease. The Company has operating leases primarily consisting of facilities with remaining lease terms of 1 year to 11 years. The lease term represents the non-cancelable period of the lease. For certain leases, the Company has an option to extend the lease term. These renewal options are not considered in the remaining lease term unless it is reasonably certain that the Company will exercise such options.
Refer to Note 4, “Leases,” for additional information.
Foreign Currency
The functional currency of the Company’s Israeli and Swiss subsidiaries is the U.S. dollar. All other foreign subsidiaries use the respective local currency as the functional currency. When the local currency is the functional currency, gains and losses from translation of these foreign currency financial statements into U.S. dollars are recorded as a separate component of other comprehensive income (loss) in stockholders’ equity.
The Company’s foreign currency exposure is also related to its net position of monetary assets and monetary liabilities held by its foreign subsidiaries in their nonfunctional currencies. These monetary assets and liabilities are being remeasured into the subsidiaries’ respective functional currencies using exchange rates as of the balance sheet date. Such remeasurement gains and losses are included in “Other income (expense), net” in the Company’s Consolidated Statements of Operations. During the year ended December 31, 2021, the Company recorded remeasurement gain of approximately $0.6 million. During the years ended December 31, 2020 and 2019, the Company recorded remeasurement loss of $1.0 million and $1.5 million, respectively.
Derivative Instruments
The Company enters into derivative instruments, primarily foreign currency forward contracts, to minimize the short-term impact of foreign currency exchange rate fluctuations on certain foreign currency denominated assets and liabilities as well as certain foreign currencies denominated expenses. The Company does not enter into derivative instruments for trading purposes and these derivatives generally have maturities within three months.
The derivative instruments are recorded at fair value in prepaid expenses and other current assets or accrued and other current liabilities in the Company’s Consolidated Balance Sheets. The Company enters into derivative instruments to hedge existing foreign currency denominated assets or liabilities, the gains or losses on these hedges are recorded immediately in earnings to offset the changes in the fair value of the assets or liabilities being hedged.
Research and Development
Research and development (“R&D”) costs are expensed as incurred and consists primarily of employee salaries and related expenses, contractors and outside consultants, supplies and materials, equipment depreciation and facilities costs, all associated with the design and development of new products and enhancements of existing products.
The Company’s French subsidiary participates in the French Crédit d’Impôt Recherche (“CIR”) program which allows companies to monetize eligible research expenses. The R&D credits receivable from the French government for spending on innovative R&D under the CIR program is recorded as an offset to R&D expenses. In the years ended December 31, 2021, 2020 and 2019, the Company had R&D credits of $5.7 million, $4.5 million and $4.7 million, respectively.
57

Table of Contents
Restructuring and Related Charges
The Company’s restructuring charges consist primarily of employee severance, one-time termination benefits related to the reduction of its workforce, and other costs. Liabilities for costs associated with a restructuring activity are recognized when the liability is incurred and are measured at fair value. One-time termination benefits are expensed at the date the entity notifies the employee, unless the employee must provide future service, in which case the benefits are expensed ratably over the future service period. Termination benefits are calculated based on regional benefit practices and local statutory requirements.
Refer to Note 10, “Restructuring and Related Charges,” for additional information.
Warranty
The Company accrues for estimated warranty costs at the time of revenue recognition and records such accrued liabilities as part of cost of revenue. Management periodically reviews its warranty liability and adjusts the accrued liability based on the terms of warranties provided to customers, historical and anticipated warranty claims experience, and estimates of the timing and cost of warranty claims.
Advertising Expenses
All advertising costs are expensed as incurred and included in “Selling, general and administrative expenses” in the Company’s Consolidated Statements of Operations. Advertising expense was $1.0 million, $1.1 million and $0.7 million for the years ended December 31, 2021, 2020 and 2019, respectively.
Stock-based Compensation
The Company measures and recognizes compensation expense for all stock-based compensation awards made to employees, including stock options, restricted stock units (“RSUs”) and stock purchase rights under the Company’s Employee Stock Purchase Plan (“ESPP”), based upon the grant-date fair value of those awards. The Company recognizes the impact of forfeitures as they occur.
The fair value of the Company’s stock options and stock purchase rights under ESPP is estimated at grant date using the Black-Scholes option pricing model. The fair value of the Company’s RSUs and performance-based RSUs (“PRSUs”) is calculated based on the market value of the Company’s stock at the grant date. The fair value of the Company’s market-based RSUs (“MRSUs”) is estimated using the Monte-Carlo valuation model with market vesting conditions.
The Company recognizes the stock-based compensation for options, RSUs, MRSUs and stock purchase rights under ESPP on straight-line basis over the requisite service period, which is generally the vesting period. The Company recognizes the stock-based compensation for PRSUs based on the probability of achieving performance criteria defined in the PRSU agreements. The Company estimates the number of PRSUs ultimately expected to vest and recognizes expense using the graded vesting attribution method over the requisite service period. Changes in the estimates related to probability of achieving certain performance criteria and number of PRSUs expected to vest could significantly affect the related stock-based compensation expense from one period to the next.
Pension Plan
Under French law, the Company’s subsidiary in France is obligated to provide for a defined benefit plan to its employees upon their retirement from the Company. The Company’s defined benefit pension plan in France is unfunded.
The Company records its obligations relating to the pension plans based on calculations which include various actuarial assumptions including employees’ age and period of service with the company; projected mortality rates, mobility rates and increases in salaries; and a discount rate. The Company reviews its actuarial assumptions on an annual basis as of December 31 (or more frequently if a significant event requiring remeasurement occurs) and modifies the assumptions based on current rates and trends when it is appropriate to do so. The Company believes that the assumptions utilized in recording its obligations under its pension plan are reasonable based on its experience, market conditions and input from its actuaries.
The Company accounts for the actuarial gains (losses) in accordance with ASC 715, “Compensation - Retirement Benefits.” If the net accumulated gain or loss exceeds 10% of the projected plan benefit obligation, a portion of the net gain or loss is amortized and included in expense for the following year based upon the average remaining service period of active plan participants, unless the Company’s policy is to recognize all actuarial gains (losses) when they occur. The Company elected to defer actuarial gains (losses) in accumulated other comprehensive income (loss). As of December 31, 2021, the Company did not meet the 10% threshold, and therefore no amortization of 2021 actuarial gain would be recorded in 2022.
Refer to Note 12, “Employee Benefit Plans” for additional information.

Income Taxes
In preparing the Company’s consolidated financial statements, the Company estimates the income taxes for each of the jurisdictions in which the Company operates. This involves estimating the Company’s current tax expense and assessing temporary and permanent differences resulting from differing treatment of items, such as reserves and accruals, for tax and accounting purposes. These temporary differences result in deferred tax assets and liabilities, which are included within the Company’s Consolidated Balance Sheets.
The Company’s income tax policy is to record the estimated future tax effects of temporary differences between the tax bases of assets and liabilities and amounts reported in the Company’s accompanying Consolidated Balance Sheets, as well as operating loss and tax credit carryforwards. The Company follows the guidelines set forth in the applicable accounting guidance regarding the recoverability of any tax assets recorded on the Consolidated Balance Sheets and provides any necessary allowances as required. Determining necessary allowances requires the Company to make assessments about the timing of future events, including the probability of expected future taxable income and available tax planning opportunities. A history of operating losses in recent years has led to uncertainty with respect to our ability to realize certain of our net deferred tax assets, and as a result we applied a full valuation allowance against our U.S. net deferred tax assets as of December 31, 2021. In the event that actual results differ from these estimates or the Company adjusts these estimates in future periods, the Compa ny’s operating results, and financial position could be materially affected.
The Company is subject to examination of its income tax returns by various tax authorities on a periodic basis. The Company regularly assesses the likelihood of adverse outcomes resulting from such examinations to determine the adequacy of its provision for income taxes. The Company has applied the provisions of the applicable accounting guidance on accounting for uncertainty in income taxes, which requires application of a more-likely-than-not threshold to the recognition and de-recognition of uncertain tax positions. If the recognition threshold is met, the applicable accounting guidance permits the Company to recognize a tax benefit measured at the largest amount of tax benefit that, in the Company’s judgment, is more than 50% likely to be realized upon settlement. It further requires that a change in judgment related to the expected ultimate resolution of uncertain tax positions be recognized in earnings in the period of such change.
The Company files annual income tax returns in multiple taxing jurisdictions around the world. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes that its reserves for income taxes reflect the most likely outcome. The Company adjusts these reserves and penalties, as well as the related interest, in light of changing facts and circumstances. Changes in the Company’s assessment of its uncertain tax positions or settlement of any particular position could materially and adversely impact the Company’s income tax rate, operating results, financial position and cash flows.
Segment Reporting
Operating segments are defined as components of an enterprise that engage in business activities for which separate financial information is available and is evaluated by the Chief Operating Decision Maker (“CODM”), which for the Company is its Chief Executive Officer, in deciding how to allocate resources and assess performance. The Company has two operating segments: Video and Cable Access.
Recently Issued Accounting Pronouncements
In August 2020, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the accounting for convertible instruments and contracts on an entity’s own equity. Among other changes, ASU No. 2020-06 removes from U.S. GAAP the liability and equity separation model for convertible instruments with a cash conversion feature, and as a result, after adoption, entities will no longer separately present in equity an embedded conversion feature for such debt. Similarly, the embedded conversion feature will no longer be amortized into income as interest expense over the life of the instrument. Instead, entities will account for a convertible debt instrument wholly as debt unless (1) a convertible instrument contains features that require bifurcation as a derivative under ASC Topic 815, Derivatives and Hedging, or (2) a convertible debt instrument was issued at a substantial premium. The new ASU is effective for interim and annual periods beginning after December 15, 2021, with early adoption permitted after December 15, 2020, and can be adopted either be on a modified retrospective or full retrospective basis.
The Company will adopt this ASU on January 1, 2022 on a modified retrospective basis. The adoption is expected to reduce additional paid-in capital and convertible debt (mezzanine equity) by approximately $32.2 million and $0.9 million, respectively, due to the recombination of the equity conversion component of outstanding convertible debt, which was initially separated and recorded in stockholders’ equity, and to remove the remaining debt discount of approximately $15.2 million related to this previous separation. The net effect of these adjustments will be recorded as a reduction in the balance of the opening accumulated deficit as of January 1, 2022.
59

Table of Contents
The Company currently expects that the adoption of this ASU will result in the reduction of non-cash interest expense for the year ending December 31, 2022 and future periods until the settlement of the remaining outstanding Notes. The required use of if-converted method to calculate the impact of convertible notes on diluted earnings per share is not expected to have a material impact. During the fourth quarter of fiscal 2021, the Company and the trustee for 2022 Notes and 2024 Notes entered into supplemental indentures for both the 2022 Notes and 2024 Notes. Pursuant to the supplemental indentures, the Company eliminated its option to settle the principal amount of the Notes in shares of the Company's common stock upon conversion. Accordingly, the dilutive effect of the Company's 2022 Notes and 2024 Notes will be limited to the conversion premium. The adoption of this ASU will have no impact on the consolidated statement of cash flows.
From time to time, new accounting pronouncements are issued by the FASB, or other standards setting bodies, that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes the impact of recently issued standards that are not yet effective will not have a material impact on its consolidated financial position, results of operations and cash flows upon adoption.
NOTE 3: REVENUE
Hardware and Software. Revenue from the sale of hardware and software products is recognized when the control is transferred. For most of the Company’s product sales (including sales to distributors and system integrators), the control is transferred at the time the product is shipped or delivery has occurred because the customer has significant risks and rewards of ownership of the asset and the Company has a present right to payment at that time. The Company’s agreements with the distributors and system integrators have terms which are generally consistent with the standard terms and conditions for the sale of the Company’s equipment to end users, and do not provide for product rotation or pricing allowances, as are typically found in agreements with stocking distributors. The Company offers return rights which are specifically identified and accrued for as sales returns at the end of the period.
Shipping and handling costs are accounted for as a fulfillment cost and are recorded in “Cost of revenue” in the Company’s Consolidated Statements of Operations. Sales tax and other amounts collected on behalf of third parties are excluded from the transaction price.
Arrangements with Multiple Performance Obligations. The Company has revenue arrangements that include multiple performance obligations. The Company allocates transaction price to all separate performance obligations based on their relative standalone selling prices (“SSP”). The Company may exercise judgment when determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together.
The Company allocates transaction price to all separate performance obligations based on their relative SSP. The Company’s best evidence for SSP is the price the Company charges for that good or service when the Company sells it separately in similar circumstances to similar customers. If goods or services are not always sold separ ately, the Company uses its estimate of SSP in the allocation of transaction price. The objective of determining the best estimate of SSP is to estimate the price at which the Company would transact a sale if the product or service were sold on a standalone basis. The Company’s process for determining best estimate of SSP involves management’s judgment, and considers multiple factors including, but not limited to, major product groupings, geographies, gross margin objectives and pricing practices. Pricing practices taken into consideration include contractually stated prices, discounts offered and applicable price lists. These factors may vary over time, depending upon the unique facts and circumstances related to each deliverable. If the facts and circumstances underlying the factors considered change or should future facts and circumstances lead the Company to consider additional factors, the Company’s best estimate of SSP may also change.
If the Company has not yet established a selling price because the good or service has not previously been sold on a standalone basis, SSP for such good and service in a contract with multiple performance obligations is determined by applying a residual approach whereby all other performance obligations within a contract are first allocated a portion of the transaction price based upon their respective SSP, using observable prices, with any residual amount of the transaction price allocated to the good or service for which the price has not yet been established.

Table of Contents
Solution Sales. Solution sales for the design, manufacture, test, integration and installation of products, including equipment acquired from third parties to be integrated with Harmonic’s products, that are customized to meet the customer’s specifications are accounted for based on the percentage-of-completion basis, using the input method. Some of our arrangements may include acceptance provisions that require testing of the solution against specific performance criteria. The Company performs a detailed evaluation to determine whether the arrangement involves performance criteria based on our standard performance criteria. The Company has a long-standing history of entering into contractual arrangements to deliver the solution sales based on standard performance criteria. For this type of arrangement, we consider the customer acceptance clause not substantive and recognize product revenue when the customer takes possession of the product and recognize service on a percentage-of-completion basis using the input method. However, if the solution results in significant production, modification or customization, we consider the arrangement as a single performance obligation and recognize the revenue at a point in time, depending on the complexity of the solution and nature of acceptance.
Professional services. Revenue from professional services is recognized over time as the services are performed or on the percentage-of-completion basis using the input method.
Input method. The use of the input method requires the Company to make reasonably dependable estimates. We use the input method based on labor hours, where revenue is calculated based on the percentage of total hours incurred in relation to total estimated hours at completion of the contract. The input method is reasonable because the hours best reflect the Company’s efforts toward satisfying the performance obligation over time. As circumstances change over time, the Company updates its measure of progress to reflect any changes in the outcome of the performance obligation. Such changes to an entity’s measure of progress are accounted for as a change in accounting estimates.
Support and maintenance. Support and maintenance services are satisfied ratably over time as the customer simultaneously receives and consumes the benefits of the services.
Contract Balances. Deferred revenue represents the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration (or an amount of consideration is due) from the customer. The Company’s payment terms vary by the type and location of its customer and the products or services offered. The term between invoicing and when payment is due is not significant. For certain products or services and customer types, the Company requires payment before the products or services are delivered to the customer.
Revenue recognized during the year ended December 31, 2021 that was included within the deferred revenue balance at January 1, 2021 was $52.2 million. Revenue recognized during the year ended December 31, 2020 that was included within the deferred revenue balance at January 1, 2020 was $36.2 million.
Contract assets exist when the Company has satisfied a performance obligation but does not have an unconditional right to consideration (e.g., because the entity first must satisfy another performance obligation in the contract before it is entitled to invoice the customer).
Contract assets and deferred revenue consisted of the following:

| As of December 31,
(in thousands) | 2021 |  | 2020
Contract assets | $ | 8,101 |  |  | $ | 9,800 |
Deferred revenue | 78,167 |  |  | 63,533 |

Contract assets and the non-current portion of Deferred revenue are reported as components of “Prepaid expenses and other current assets” and “Other non-current liabilities,” respectively, on the Consolidated Balance Sheets.
Remaining performance obligations represent contracted revenues that had not yet been recognized and future revenue recognition is expected. The aggregate balance of the Company’s remaining performance obligations as of December 31, 2021, was $461.7 million, of which approximately 83% is expected to be recognized as revenue over the next 12 months and the remainder thereafter.
Contract costs. The incremental costs of obtaining a contract are capitalized if the costs are expected to be recovered. Costs that are recognized as assets are amortized on a straight-line basis over the period during which the related goods or services transfer to the customer. Costs incurred to fulfill a contract are capitalized if they are not covered by other relevant guidance, relate directly to a contract, will be used to satisfy future performance obligations, and are expected to be recovered.

Table of Contents
The balances of net capitalized contract costs included in the Company’s Consolidated Balance Sheets were as follows:

(in thousands) | As of December 31,
Balance Sheet Location | 2021 |  | 2020
Prepaid expenses and other current assets | $ | 1,907 |  |  | $ | 1,581 |
Other non-current assets | 1,636 |  |  | 1,287 |
Total net capitalized contract costs | $ | 3,543 |  |  | $ | 2,868 |

The amortization of the capitalized contract costs for the years ended December 31, 2021, 2020 and 2019 was $2.3 million, $1.6 million and $1.5 million.
Practical Expedients and Exemptions. Under Topic 606, incremental costs of obtaining a contract such as sales commissions are capitalized if they are expected to be recovered, and amortized on a straight-line basis. Expensing these costs as incurred is not permitted unless they qualify for a practical expedient. Other than capitalized costs of obtaining subscription contracts which are amortized regardless of the life of expected amortization period, the Company elected the practical expedient to expense the costs to obtain all other contracts as incurred, when the life of the expected amortization period is one year or less by using a portfolio approach.
The Company elected the practical expedient that allows the Company to not assess a contract for a significant financing component if the period between the customer’s payment and the transfer of the goods or services is one year or less.
Refer to Note 17, “Segment Information, Geographic Information and Customer Concentration” for disaggregated revenue information.
NOTE 4. LEASES
Under Topic 842, operating lease expense is generally recognized evenly over the term of the lease. The Company has operating leases primarily consisting of facilities with remaining lease terms of 1 year to 11 years. T he lease term represents the non-cancelable period of the lease. For certain leases, the Company has an option to extend the lease term. These renewal options are not considered in the remaining lease term unless it is reasonably certain that the Company will exercise such options.
The Company elected certain practical expedients under Topic 842 which are: (i) to not record leases with an initial term of twelve months or less on the balance sheet; (ii) to combine the lease and non-lease components in determining the lease liabilities and right-of-use assets, and (iii) to carry forward prior conclusions about lease identification and classification.
The Company’s lease contracts do not provide an implicit borrowing rate; hence the Company determined the incremental borrowing rate based on information available at lease commencement to determine the present value of lease liability. The Company generally uses the parent entity’s incremental borrowing rates as the treasury operations are managed centrally by the parent entity and, consequently, the pricing of leases at a subsidiary level is typically significantly influenced by the credit risk evaluated at the parent or consolidated group level on the basis of guarantees or other payment mechanisms that allow the lessor to look beyond just the subsidiary for payment.
During the fiscal year ended December 31, 2021, the Company entered into new or modified lease agreements which were assessed under Topic 842 to be operating leases. The new or modified lease agreements resulted in the balance sheet recognition of $8.8 million in “Operating lease right-of use assets,” $7.7 million in “Operating lease liabilities, long-term,” and $1.1 million in “Operating lease liabilities, current.”
The components of lease expense are as follows:

| Year ended December 31, |  |  |  |  |
(in thousands) | 2021 |  | 2020 |  |  |  |  |
Operating lease cost | $ | 7,550 |  |  | $ | 8,369 |  |  |  |  |  |

NOTE 5: DERIVATIVES AND HEDGING ACTIVITIES
Derivatives Not Designated as Hedging Instruments (Balance Sheet Hedges)
The Company’s balance sheet hedges consist of foreign currency forward contracts, which mature generally within three months. These forward contracts are carried at fair value and they are used to minimize the short-term impact of foreign currency exchange rate fluctuation on cash and certain trade and intercompany receivables and payables. Changes in the fair value of these foreign currency forward contracts are recognized in “Other expense, net” in the Consolidated Statements of Operations and are largely offset by the changes in the fair value of the assets or liabilities being hedged. Foreign currency forward contracts’ gains recognized during the years ended December 31, 2021, 2020 and 2019, were $0.7 million, $2.2 million and $1.4 million, respectively.
The U.S. dollar equivalents of all outstanding notional amounts of foreign currency forward contracts were as follows:

Purchase | $ | 2,926 |  |  | $ | 11,426 |
Sell | $ | 5,175 |  |  | $ | — |

While the Company’s arrangements with its counterparties allow for net settlement, which is designed to reduce credit risk by permitting net settlement with the same counterparty, the Company recognizes all derivative instruments in the Consolidated Balance Sheets on a gross basis. As of December 31, 2021 and 2020, gross fair values of derivative assets and liabilities, recorded as components of “Prepaid expenses and other current assets” and “Other current liabilities”, respectively, in the Consolidated Balance Sheets, were immaterial.
In connection with foreign currency derivatives entered in Israel, the Company’s subsidiaries in Israel are required to maintain a compensating balance with their bank at the end of each month. The compensating balance arrangements do not legally restrict the use of cash. As of December 31, 2021 and 2020, the total compensating balance maintained was $1.0 million.

NOTE 6: FAIR VALUE MEASUREMENTS
The applicable accounting guidance establishes a framework for measuring fair value and requires disclosure about the fair value measurements of assets and liabilities. This guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. This guidance requires the Company to classify and disclose assets and liabilities measured at fair value on a recurring basis, as well as fair value measurements of assets and liabilities measured on a nonrecurring basis in periods subsequent to initial measurement, in a three-tier fair value hierarchy as follows:
•Level 1 - Observable inputs that reflect quoted prices for identical assets or liabilities in active markets.
•Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
•Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
The carrying value of the Company’s financial instruments, including cash equivalents, restricted cash, accounts receivable, accounts payable and accrued liabilities, approximate fair value due to their short maturities.
The Company's financial instruments not measured at fair value on a recurring basis were as follows:

| December 31, 2021 |  | December 31, 2020
| Carrying |  | Fair Value |  | Carrying |  | Fair Value

The fair value of the Company’s Notes is influenced by interest rates, the Company’s stock price and stock market volatility. The difference between the carrying value and the fair value is primarily due to the spread between the conversion price and the market value of the shares underlying the conversion as of each respective balance sheet date. The Company’s French and other loans are classified within Level 2 because these borrowings are not actively traded and the majority of them have a variable interest rate structure based upon market rates currently available to the Company for debt with similar terms and maturities; therefore, the carrying value of these debts approximate its fair value. Refer to Note 11, “Convertible Notes and Other Debts,” for additional information.
During the years ended December 31, 2021, 2020, and 2019, there were no nonrecurring fair value measurements of assets and liabilities subsequent to initial recognition.
NOTE 7: GOODWILL
Goodwill represents the difference between the purchase price and the estimated fair value of the identifiable assets acquired and liabilities assumed. Goodwill is allocated among and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. The Company has two reporting units, Video and Cable Access.
During the fourth quarter of 2021, the Company performed the qualitative goodwill impairment testing for the two reporting units as part of the Company’s annual goodwill impairment test and concluded that goodwill was not impaired. The Company has not recorded any impairment charges related to goodwill in fiscal 2021, 2020 and 2019. If future economic conditions are different than those projected by management, future impairment charges may be required.

Trade accounts receivable are recorded at invoiced amounts and do not bear interest. The Company generally does not require collateral and performs ongoing credit evaluations of its customers and provides for expected losses. The Company maintains an allowance for expected credit losses based upon the expected collectability of its accounts receivable. The expectation of collectability is based on the Company’s review of credit profiles of customers, contractual terms and conditions, current economic trends and historical payment experience. The Company offers return rights which are specifically identified and accrued for as sales returns at the end of the period.
The following table is a summary of activities in allowances for expected credit losses and sales returns:

NOTE 10: RESTRUCTURING AND RELATED CHARGES
The Company has implemented several restructuring plans in the past few years. The goal of these plans was to bring operational expenses to appropriate levels relative to the Company’s net revenue, while simultaneously implementing extensive company-wide expense control programs. The restructuring plans have primarily been comprised of severance payments and termination benefits related to headcount reductions. The Company accounts for its restructuring plans under the authoritative guidance for exit or disposal activities.
The following table summarizes the activities related to the Company’s restructuring plans during the year ended December 31, 2021:

(in thousands) | Severance and Benefits

For the year ended December 31, 2021, $0.6 million and $0.1 million of restructuring and related charges are included in “Cost of revenue” and “Operating expenses - Restructuring and related charges”, respectively, in the Consolidated Statements of Operations.
NOTE 11: CONVERTIBLE NOTES AND OTHER DEBTS
4.375% Convertible Senior Notes due 2022 (the “2022 Notes”)
In June 2020, the Company issued the 2022 Notes with an aggregate principal amount of $37.7 million in a non-cash exchange for its 2020 Notes with an equal principal amount pursuant to an indenture, dated June 2, 2020 (the “2022 Notes Indenture”), by and between the Company and U.S. Bank National Association, as trustee. The 2022 Notes bear interest at a rate of 4.375% per year, payable in cash on June 1 and December 1 of each year. The 2022 Notes will mature on December 1, 2022, unless earlier repurchased by the Company, redeemed by the Company or converted pursuant to their terms.
The 2022 Notes were initially convertible into cash, shares of the Company’s common stock, par value $0.001 (“Common Stock”), or a combination thereof, at the Company’s election, at an initial conversion rate of 173.9978 shares of Common Stock per $1,000 principal amount of 2022 Notes (which is equivalent to an initial conversion price of approximately $5.75 per share). Pursuant to the supplemental indenture entered into by the Company and the trustee during the fourth quarter of fiscal 2021, the Company made an irrevocable election to settle the principal amounts of the 2022 Notes solely with cash and may pay or deliver, as the case may be, any conversion value greater than the principal amount in cash, shares of common stock or a combination thereof, at the Company’s election.
66

Table of Contents
The conversion rate, and thus the effective conversion price, may be adjusted under certain circumstances, including in connection with conversions made following certain fundamental changes and under other circumstances as set forth in the 2022 Notes Indenture.
Prior to the close of business on the business day immediately preceding September 1, 2022, the 2022 Notes will be convertible only under the following circumstances: (1) during any fiscal quarter commencing after the fiscal quarter ended on June 26, 2020 (and only during such fiscal quarter), if the last reported sale price of Common Stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of 2022 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of Common Stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. Commencing on September 1, 2022 until the close of business on the second scheduled trading day immediately preceding the maturity date, the 2022 Notes will be convertible in multiples of $1,000 principal amount regardless of the foregoing circumstances.
The 2022 Notes became convertible as of December 31, 2021, as the last reported sale price of the Company’s common stock for at least 20 trading days during a period of 30 consecutive trading days ending on December 31, 2021 was greater than 130% of the conversion price of the 2022 Notes on each applicable trading day. As a result of the 2022 Notes becoming convertible for cash up to the principal amount of $37.7 million, the Company reclassified the unamortized debt discount for the 2022 Notes in the amount of $0.9 million from “Additional paid-in capital” to “Convertible Debt” in the mezzanine equity section in the Consolidated Balance Sheet as of December 31, 2021. Additionally, all $36.8 million of the net carrying amount of the liability component of the 2022 Notes outstanding as of December 31, 2021 was classified as a current liability as of that date.
As the 2022 Notes were issued in exchange for the 2020 Notes, which was accounted for as an extinguishment, the 2022 Notes were initially accounted for at fair value, which was estimated to be $44.4 million. In accordance with the accounting guidance on embedded conversion features, the conversion feature associated with the 2022 Notes was initially valued at $8.3 million and bifurcated from the host debt instrument and recorded in “Additional paid-in capital.” The remaining amount of $36.0 million, which represents the fair value of the liability component of the 2022 Notes, was recorded as the initial carrying value of the 2022 Notes. The initial debt discount on the 2022 Notes is $1.7 million, calculated as the difference between the stated principal amount of $37.7 million and the initial carrying value of the liability component of $36.0 million. The debt discount is being amortized to interest expense at the effective interest rate over the contractual terms of the 2022 Notes.

2.00% Convertible Senior Notes due 2024 (the “2024 Notes”)
In September 2019, the Company issued $115.5 million of the 2024 Notes pursuant to an indenture (the “2024 Notes Indenture”), dated September 13, 2019, by and between the Company and U.S. Bank National Association, as trustee. The 2024 Notes bear interest at a rate of 2.00% per year, payable semi-annually on March 1 and September 1 of each year, beginning March 1, 2020. The 2024 Notes will mature on September 1, 2024, unless earlier repurchased by the Company, redeemed by the Company or converted pursuant to their terms.
The 2024 Notes were initially convertible into cash, shares of the Company’s common stock, par value $0.001 (“Common Stock”), or a combination thereof, at the Company’s election, at an initial conversion rate of 115.5001 shares of Common Stock per $1,000 principal amount of 2024 Notes (which is equivalent to an initial conversion price of approximately $8.66 per share). Pursuant to the supplemental indenture entered into by the Company and the trustee during the fourth quarter of fiscal 2021, the Company made an irrevocable election to settle the principal amounts of the 2024 Notes solely with cash and may pay or deliver, as the case may be, any conversion value greater than the principal amount in cash, shares of common stock or a combination thereof, at the Company’s election.
The conversion rate, and thus the effective conversion price, may be adjusted under certain circumstances, including in connection with conversions made following certain fundamental changes or a notice of redemption and under other circumstances, in each case, as set forth in the 2024 Notes Indenture.
The 2024 Notes will be convertible at certain times and upon the occurrence of certain events in the future, in each case, specified in the 2024 Notes Indenture. Further, on or after June 1, 2024, until the close of business on the scheduled trading day immediately preceding the maturity date, holders of the 2024 Notes may convert all or a portion of their 2024 Notes regardless of these conditions.
In accordance with the accounting guidance on embedded conversion features, the conversion feature associated with the 2024 Notes was valued at $24.9 million and bifurcated from the host debt instrument and recorded in “Additional paid-in capital.” The resulting debt discount on the 2024 Notes is being amortized to interest expense at the effective interest rate over the contractual term of the 2024 Notes.

4.00% Convertible Senior Notes due 2020 (the “2020 Notes”)
In December 2015, the Company issued $128.3 million in aggregate principal amount of the 2020 Notes pursuant to an indenture (the “2020 Notes Indenture”), dated December 14, 2015, by and between the Company and U.S. Bank National Association, as trustee. The 2020 Notes bear interest at a rate of 4.00% per year, payable in cash on June 1 and December 1 of each year. The 2020 Notes matured on December 1, 2020.

Table of Contents
The 2020 Notes were convertible into cash, shares of the Common Stock, or a combination thereof, at the Company’s election, at a conversion rate of 173.9978 shares of Common Stock per $1,000 principal amount of 2020 Notes (which is equivalent to a conversion price of approximately $5.75 per share). The conversion rate, and thus the effective conversion price, was adjustable under certain circumstances, including in connection with conversions made following certain fundamental changes and under other circumstances, in each case, as set forth in the 2020 Notes Indenture.
In September 2019, the Company used approximately $109.6 million of the net proceeds from the issuance of the 2024 Notes to repurchase $82.5 million aggregate principal of the 2020 Notes in privately negotiated transactions. The repurchase of the 2020 Notes was accounted for as a debt extinguishment, and the consideration transferred was allocated between the equity and liability components by determining the fair value of the conversion option immediately prior to the debt extinguishment and allocating that portion of the repurchase price to additional paid-in capital for $27.1 million, with the residual repurchase price allocated to the liability component, respectively. The partial repurchase of the 2020 Notes resulted in the recognition of a $5.7 million loss on debt extinguishment for the year ended December 31, 2019, which was recorded in “Loss on convertible debt extinguishment” in the Consolidated Statements of Operations.
In accordance with accounting guidance on embedded conversion features, the conversion feature associated with the 2020 Notes was initially valued at $26.1 million and bifurcated from the host debt instrument and recorded in “Additional paid-in capital.” The resulting debt discount on the 2020 Notes had been amortized to interest expense at the effective interest rate over the contractual terms of the 2020 Notes prior to the maturity date in December 2020.
The 2020 Notes became convertible as of December 31, 2019, as the last reported sale price of the Company’s common stock for at least 20 trading days during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter was greater than or equal to 130% of the conversion price of the 2020 Notes on each applicable trading day. As a result of the 2020 Notes becoming convertible for cash up to the principal amount of $45.8 million, the Company reclassified the unamortized debt discount for the 2020 Notes in the amount of $2.4 million from “Additional paid-in-capital” to convertible debt in the mezzanine equity section in the Consolidated Balance Sheets as of December 31, 2019. During the year ended December 31, 2020, this conversion condition was not present, and accordingly, the Company reclassified this balance from convertible debt in the mezzanine equity section to “Additional paid-in-capital.”
In June 2020, the Company exchanged $37.7 million in aggregate principal amount of the 2020 Notes for $37.7 million in aggregate principal amount of its 2022 Notes. The fair value of the consideration transferred in the form of the 2022 Notes of $44.4 million was allocated between the equity and liability components as discussed in the 2022 Notes section above. The exchange of the 2020 Notes was accounted for as a debt extinguishment, which resulted in the recognition of a $0.8 million loss on debt extinguishment for the year ended December 31, 2020, which was recorded in “Loss on convertible debt extinguishment” in the Consolidated Statements of Operations. Following the exchange, there was a total of $8.1 million aggregate principal amount of the 2020 Notes remaining.
On or after September 1, 2020, until the close of business on the scheduled trading day immediately preceding the maturity date, holders of the 2020 Notes were able to convert all or a portion of their 2020 Notes regardless of any conditions.
Prior to maturity date, a total of $7.8 million of the principal balance was converted by holders of the 2020 Notes. In accordance with provisions of the 2020 Notes Indenture, conversion was settled in a combination of cash and the Company’s Common Stock. The conversion resulted in the recognition of a $0.5 million loss, which was recorded in “Loss on convertible debt extinguishment” in the Consolidated Statements of Operations. The remaining principal of $0.3 million matured on December 1, 2020 and was paid in cash.

During fiscal 2020, the Company amended the Credit Agreement to extend the Credit Agreement maturity date to October 30, 2022 and amend the interest rates for the revolving loans. As amended, the revolving loans bear interest, at the Company’s election, at a floating rate per annum equal to either (1) 2.00% plus the greater of (i) 1 month LIBOR on any day plus 2.50% and (ii) the prime rate as reported in the Wall Street Journal from time to time or (2) 3.00% plus LIBOR for an interest period of one, two or three months. Interest on the revolving loans is payable monthly in arrears, in the case of prime rate loans, and at the end of the applicable interest period, in the case of LIBOR loans.
The Credit Agreement contains customary affirmative and negative covenants, including covenants limiting the ability of the Company, among other things, incur debt, grant liens, undergo certain fundamental changes, make investments, make certain restricted payments, dispose of assets, enter into transactions with affiliates, and enter into burdensome agreements, in each case, subject to limitations and exceptions set forth in the Credit Agreement. The Company is also required to maintain compliance with an adjusted quick ratio, a minimum EBITDA covenant (tested quarterly) and a minimum liquidity covenant, in each case, determined in accordance with the terms of the Credit Agreement. As of December 31, 2021, the Company was in compliance with the covenants under the Credit Agreement.
There were no borrowings under the Credit Agreement outstanding as of December 31, 2021.

Relief Loans
In June 2020, Harmonic France was granted a loan from Société Générale S.A. (the “SG Loan”) in the aggregate amount of 5 million Euros, pursuant to a state guarantee program introduced in March 2020 to provide relief to companies from the financial consequences of the COVID-19 pandemic. The SG Loan was initially maturing in June 2021. During 2021, SG Loan maturity was extended to June 2026. The SG loan bears an effective interest rate of 0.51% per annum payable annually and may be repaid at any time prior to maturity with no repayment penalties. There are no restrictions on the use of funds from the SG Loan. The purpose of the funds from the SG Loan is to allow the preservation of activity and employment in France. As of December 31, 2021, there was $5.7 million outstanding under the loan, which is recorded in “Other debts, non-current” in the Consolidated Balance Sheets.
In April 2020, Harmonic International GmbH was granted a loan of CHF 500,000 from UBS Switzerland AG (the “UBS Loan”) in accordance with a Swiss federal COVID-19 loan guarantee program with an initial maturity of five years. The exclusive purpose of the UBS Loan is to guarantee the Company’s current liability requirements. The UBS Loan did not bear any interest. The UBS Loan was repaid in full during 2021.
NOTE 12: EMPLOYEE BENEFIT PLANS
Equity Award Plans
1995 Stock Plan
The 1995 Stock Plan provides for the grant of incentive stock options, non-statutory stock options and restricted stock units (“RSUs”). Incentive stock options may be granted only to employees. All other awards may be granted to employees and non-employees. Under the terms of the 1995 Stock Plan, no incentive stock option or non-statutory stock option may be granted in the ordinary course of business with a per share exercise price that is less than 100% of the fair value of the Company’s common stock on the date of grant. RSUs have no exercise price. Both options and RSUs vest over a period of time as determined by the Company’s Board of Directors (the “Board”), generally two to four years, and options expire seven years from the date of grant. Some of the RSUs granted by the Company have performance-based vesting terms, where vesting is dependent on achievement of certain financial and non-financial operating goals of the Company (performance-based RSUs, or “PRSUs”), or where vesting is dependent on performance of the Company’s total shareholder return (“TSR”) relative to the TSR of the NASDAQ Telecommunication Index (market-based RSUs, or “MRSUs”). A s of December 31, 2021, an aggregate of 7,317,622 shares of common stock were reserved for issuance under the 1995 Stock Plan, of which 3,223,471 shares remained available fo r future grants.
2002 Director Plan
The 2002 Director Plan provides for the grant of non-statutory stock options and RSUs to non-employee directors of the Company. Under the terms of the 2002 Director Plan, no non-statutory stock option may be granted with a per share exercise price that is less than 100% of the fair value of the Company’s common stock on the date of grant. RSUs have no exercise price. Both options and RSUs vest over a period of time as determined by the Board, generally one year for RSUs and three years for options, and options expire seven years from the date of grant. As of December 31, 2021, an aggregate of 800,182 shares of common stock were reserved for issuance under the 2002 Director Plan, of which 628,749 shares remained available fo r future grants.
Employee Stock Purchase Plan
The 2002 Employee Stock Purchase Plan (“ESPP”) provides for the issuance of share purchase rights to employees of the Company. The ESPP is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. The ESPP enables employees to purchase shares at 85% of the fair market value of the Common Stock at the beginning or end of the offering period, whichever is lower. Offering periods generally begin on the first trading day on or after January 1 and July 1 of each year. Employees may participate through payroll deductions of 1% to 10% of their earnings. In the event that there are insufficient shares in the plan to fully fund the issuance, the available shares will be allocated across all participants based on their contributions relative to the total contributions received for the offering period. Under the ESPP, 1,024,244, 1,036,543 and 1,037,366 shares were issued during fiscal 2021, 2020 and 2019, respectively, representing $5.1 million, $4.5 million and $4.1 million in contributions. As of December 31, 2021, 1,184,205 shares were reserved for future purchases by eligible employees.

French Pension Plan
Under French law, the Company’s subsidiaries in France are obligated to make certain payments to their employees upon their retirement from the Company. These payments are based on the retiring employee’s salary for a number of months that varies according to the employee’s period of service and position. Salary used in the calculation is the employee’s average monthly salary for the twelve months prior to retirement. The payments are made in one lump-sum at the time of retirement. The French pension plan is unfunded and there are no contributions to the plan required by related laws or funding regulations. No required contributions are expected in fiscal 2022, but the Company, at its discretion, may make contributions to the defined benefit plan.
The Company’s defined benefit pension obligations are measured annually as of December 31. The present value of these lump-sum payments is determined on an actuarial basis and the actuarial valuation considers the employees’ age and period of service with the Company, projected mortality rates, mobility rates, increases in salaries and a discount rate.

As of December 31, 2021, total unrecognized share-based compensation cost related to unvested RSUs was $18.3 million and is expected to be recognized over a weighted-average period of approximately 1.5 years.
Valuation Assumptions
The Company estimates the fair value of stock purchase rights under the ESPP using a Black-Scholes option valuation model. The value of the stock purchase rights under the ESPP consists of: (1) the 15% discount on the purchase of the stock; (2) 85% of the fair value of the call option; and (3) 15% of the fair value of the put option. The call option and put option were valued using the Black-Scholes option pricing model. At the date of grant, the Company estimated the fair value of each stock purchase right granted under the ESPP using the following weighted average assumptions:

|  |  | Year ended December 31,
|  |  |  |  |  |  |  | 2021 |  | 2020 |  | 2019
Expected term (in years) |  |  |  |  |  |  |  | 0.50 |  | 0.50 |  | 0.50
Volatility |  |  |  |  |  |  |  | 45 | % |  | 56 | % |  | 38 | %
Risk-free interest rate |  |  |  |  |  |  |  | 0.1 | % |  | 0.9 | % |  | 2.3 | %
Expected dividends |  |  |  |  |  |  |  | 0.0 | % |  | 0.0 | % |  | 0.0 | %

The expected term of the stock purchase right under ESPP represents the period of time from the beginning of the offering period to the purchase date. The Company uses its historical volatility for a period equivalent to the expected term to estimate the expected volatility. The risk-free interest rate that the Company uses in the Black-Scholes option valuation model is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term. The Company has not paid and does not plan to pay any cash dividends in the foreseeable future.
The estimated weighted-average fair value per share of stock purchase rights under the ESPP, granted for the years ended December 31, 2021, 2020 and 2019 was $2.24, $1.80 and $1.33, respectively.

Effective tax rate | (49) | % |  | (12) | % |  | 10 | %

The Company operates in multiple jurisdictions and its profits are taxed pursuant to the tax laws of these jurisdictions. The Company’s effective income tax rate differs from the U.S. federal statutory rate primarily due to geographical mix of income and losses, full valuation allowance against U.S. federal and state deferred tax assets, foreign withholding taxes and income taxes on earnings from operations in foreign tax jurisdictions. The Company’s effective income tax rate may be affected by changes in its interpretations of tax laws and tax agreements in any given jurisdiction, utilization of net operating loss and tax credit carry forwards, changes in geographical mix of income and expense, and changes in management's assessment of matters such as the ability to realize deferred tax assets, as well as one-time discrete items. During fiscal 2021, the Company recorded a one-time benefit of approximately $8.6 million due to the release of valuation allowance on deferred tax assets in foreign jurisdictions due to its improved earnings in recent years and increasing future projected earnings. During fiscal 2019, the Company recorded a one-time benefit of approximately $2.0 million due to changes in the Company's global tax structure, and a $0.8 million benefit from a valuation allowance release for one of its foreign subsidiaries. This release of the valuation allowance was due to changes in forecasted taxable income resulting from the Company receiving a favorable tax ruling during 2019.

Management regularly assesses the ability to realize deferred tax assets recorded based upon the weight of available evidence, including such factors as recent earnings history and expected future taxable income on a jurisdiction by jurisdiction basis. In the event that the Company changes its determination as to the amount of realizable deferred tax assets, the Company will adjust its valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.
As of December 31, 2021, the Company had $103.6 million, $61.8 million, $61.1 million of foreign, U.S. federal and state net operating loss (“NOL”) carryforwards, respectively. Certain foreign NOLs expire beginning in 2026, if not utilized, while the majority of the foreign NOLs carryforward indefinitely. $28.9 million of U.S. federal NOL carryforward expires at various dates beginning in 2022 through 2037, if not utilized, and the remainder carries forward indefinitely. Certain U.S. states NOL carryforward expires at various dates beginning in 2029, if not utilized.
As of December 31, 2021, the Company had U.S. federal and California state tax credit carryforwards of $15.5 million and $37.3 million, respectively. If not utilized, the U.S. federal tax credit carryforwards will begin to expire in 2031, while the California tax credit carryforward will not expire.
In the event the Company experiences an ownership change within the meaning of Section 382 of the Internal Revenue Code (“IRC”), the Company’s ability to utilize net operating losses, tax credits and other tax attributes may be limited.
The Company has not provided U.S. state income taxes and foreign withholding taxes on approximately $42.0 million of cumulative earnings for certain non-U.S. subsidiaries, because such earnings are intended to be indefinitely reinvested. Determination of the amount of unrecognized deferred tax liability for temporary differences related to investments in these non-U.S. subsidiaries that are essentially permanently in duration is not practicable.

Table of Contents
The Company applies the provisions of the applicable accounting guidance regarding accounting for uncertainty in income taxes, which require application of a more-likely-than-not threshold to the recognition and derecognition of uncertain tax positions. If the recognition threshold is met, the applicable accounting guidance permits the recognition of a tax benefit measured at the largest amount of such tax benefit that, in the Company’s judgment, is more than fifty percent likely to be realized upon settlement. It further requires that a change in judgment related to the expected ultimate resolution of uncertain tax positions to be recognized in earnings in the period in which such determination is made. The Company will continue to review its tax positions and provide for, or reverse, unrecognized tax benefits as issues arise. As of December 31, 2021, none of unrecognized future tax benefits would favorably impact the effective tax rate in the future due to a full valuation allowance in the United States. The following table summarizes the activities related to the Company’s gross unrecognized tax benefits:

The Company recognizes interest and penalties related to unrecognized tax positions in income tax expenses on the Consolidated Statements of Operations. The net interest and penalties charges recorded for the years ended December 31, 2019 through 2021, were not material.
The 2015 through 2021 tax years generally remain subject to examination by U.S. federal and most state tax authorities. In addition, the Company remains subject to income tax examination for several other jurisdictions, including in Switzerland for years after 2016, Israel for years after 2019, and France for years after 2016.
NOTE 15: WARRANTS
On September 26, 2016, the Company granted a warrant to purchase shares of common stock (the “Warrant”) to Comcast pursuant to which Comcast may, subject to certain vesting provisions, purchase up to 7,816,162 shares of the Company’s common stock subject to adjustment in accordance with the terms of the Warrant, for a per share exercise price of $4.76.
Prior to the third quarter of fiscal 2019, Comcast had vested in 1,954,042 Warrant shares as a result of the achievement of certain milestones. On July 8 2019, in connection with the election by Comcast of enterprise licensing pricing for the Company’s CableOS software, the Company deemed that all of the remaining milestones and thresholds required to fulfill each of the vesting requirements of the Warrant were satisfied and achieved or otherwise waived such that all Warrant shares were fully vested and exercisable as of July 1, 2019. The remaining terms of the Warrant have not been modified or amended. The total fair value of the fully vested Warrants as of July 1, 2019 was $20.0 million, which includes $3.9 million in fair value for the Warrant shares which were vested prior to July 2019.
The fair value of the Warrant that vested in connection with the CableOS software license agreement was estimated to be $16.1 million on July 8, 2019, using the Black-Scholes option pricing model. The assumptions utilized in the Black-Scholes model included the risk-free interest rate, expected volatility, and expected life in years. The risk-free interest rate was based on the U.S. Treasury yield curve rates with maturity terms similar to the expected life of the Warrant, which was determined to be 1.9%. Expected volatility was determined utilizing historical volatility over a period of time equal to the expected life of the Warrant, which was determined to be 48.6%. Expected life was equal to the remaining contractual term of the Warrant, which was determined to be 4.2 years. The dividend yield was assumed to be zero since the Company had not historically declared dividends and did not have any plans to declare dividends in the future.
The fair value of the Warrant was recorded as a component of “Prepaid expenses and other current assets” and “Other non-current assets” with a corresponding offset to “Additional paid-in capital” on the Company’s Consolidated Balance Sheets. This asset is being amortized as a reduction to the Company’s revenue, based on the recognition pattern of the related transaction price.
During the years ended December 31, 2021, 2020 and 2019, the Company recorded $1.7 million, $1.7 million and $13.6 million, respectively, as a reduction to net revenues in connection with amortization of the Warrant.
On December 17, 2019, Comcast exercised the Warrant in its entirety, resulting in a net issuance of 3,217,547 shares.

NOTE 16: EARNINGS PER SHARE
Basic net income (loss) per share is computed by dividing the net income (loss) attributable to common stockholders for the applicable period by the weighted average number of common shares outstanding during the period. Potentially dilutive shares, consisting of outstanding stock options, RSUs, ESPP awards, warrants, and the Company’s Notes, are included in calculation of diluted net income (loss) per share when their effect is dilutive.
The following table sets forth the computation of the basic and diluted net income (loss) per share:

| Year ended December 31,
(in thousands, except per share amounts) | 2021 |  | 2020 |  | 2019
Numerator: |  |  |  |  |
Net income (loss) | $ | 13,254 |  |  | $ | (29,271) |  |  | $ | (5,924) |
Denominator: |  |  |  |  |
Weighted average number of shares outstanding: |  |  |  |  |
Basic | 101,484 |  |  | 96,971 |  |  | 89,575 |
2020 Notes | 2,175 |  |  | — |  |  | — |
2024 Notes | 653 |  |  | — |  |  | — |
Stock options | 292 |  | — |  |  | — |
Restricted stock units | 1,525 |  |  | — |  |  | — |
Stock purchase rights under ESPP | 42 |  | — |  |  | — |
Diluted | 106,171 |  |  | 96,971 |  |  | 89,575 |
Net income (loss) per share: |  |  |  |  |
Basic | $ | 0.13 |  |  | $ | (0.30) |  |  | $ | (0.07) |
Diluted | $ | 0.12 |  |  | $ | (0.30) |  |  | $ | (0.07) |

The following table presents the potentially dilutive shares that were excluded from the computation of diluted net income (loss) per share, because their effect was anti-dilutive:

| Year ended December 31,
(in thousands) | 2021 |  | 2020 |  | 2019
2020 Notes | — |  |  | 312 |  |  | 1,322 |
2022 Notes | — |  |  | 192 |  |  | n/a
Stock options | 8 |  |  | 1,603 |  |  | 2,568 |
Restricted stock units | 27 |  |  | 3,041 |  |  | 2,955 |
Stock purchase rights under the ESPP | 390 |  |  | 531 |  |  | 478 |
Warrants (1) | — |  |  | — |  |  | 4,321 |
Total | 425 |  |  | 5,679 |  |  | 11,644 |

(1) Refer to Note 15, “Warrants,” for additional information.
The Company applies the treasury stock method to determine the potential dilutive effect of its convertible debt on earnings per share. The 2020 Notes, 2022 Notes, and 2024 Notes are excluded from the calculation of diluted earnings per share under the treasury stock method for the periods when their respective conversion prices exceeded the average market price for the Company's common stock. Under the if-converted method, the 2022 Notes and the 2024 Notes have potential dilutive effect of 6.6 million shares and 13.3 million shares, respectively.

NOTE 17: SEGMENT INFORMATION, GEOGRAPHIC INFORMATION AND CUSTOMER CONCENTRATION
Segment Information
Operating segments are defined as components of an enterprise that engage in business activities for which separate financial information is available and evaluated by the Company’s CODM, which for the Company is its Chief Executive Officer, in deciding how to allocate resources and assess performance. Based on the internal reporting structure, the Company consists of two operating segments: Video and Cable Access. The operating segments were determined based on the nature of the products offered. The Video segment provides video processing and production and playout solutions and services worldwide to broadcast and media companies, streaming new media companies, cable operators, and satellite and telco Pay-TV service providers. The Cable Access segment provides CableOS cable access solutions and related services to cable operators globally. A measure of assets by segment is not applicable as segment assets are not included in the discrete financial information provided to the CODM.
The following table provides summary financial information by reportable segment:

| Year ended December 31,

Operating income | $ | 44,059 |  |  | $ | 12,977 |  |  | $ | 38,008 |

A reconciliation of the Company’s total segment operating income to income (loss) before income taxes in as follows:

Total segment operating income | $ | 44,059 |  |  | $ | 12,977 |  |  | $ | 38,008 |
Unallocated corporate expenses (1) | (681) |  |  | (3,416) |  |  | (4,532) |

Loss on convertible debt extinguishment | — |  |  | (1,362) |  |  | (5,695) |
Non-operating expense, net | (9,938) |  |  | (12,406) |  |  | (13,984) |
Income (loss) before income taxes | $ | 8,871 |  |  | $ | (26,217) |  |  | $ | (6,596) |

(1) Together with amortization of intangibles and stock-based compensation, the Company does not allocate restructuring and related charges and certain other non-recurring charges to the operating income for each segment because management does not include this information in the measurement of the performance of the operating segments.

Customer Concentration
One customer, Comcast, accounted for 26%, 20% and 23% of the Company’s total net revenues during the years ended December 31, 2021, 2020 and 2019, respectively.
NOTE 18: COMMITMENTS AND CONTINGENCIES
Bank Guarantees and Standby Letters of Credit
As of December 31, 2021 and 2020, the Company has outstanding bank guarantees and standby letters of credit in aggregate of $2.4 million and $3.3 million, respectively, consisting of building leases and performance bonds issued to customers.
During 2017, one of the Company’s subsidiaries entered into a $2.0 million credit facility with a foreign bank for the purpose of issuing performance guarantees. The credit facility is secured by a $2.3 million guarantee issued by the Company. There were no amounts outstanding under this credit facility as of December 31, 2021 and 2020.
Indemnification
The Company is obligated to indemnify its officers and its directors pursuant to its bylaws and contractual indemnity agreements. The Company also indemnifies some of its suppliers and most of its customers for specified intellectual property matters pursuant to certain contractual arrangements, subject to certain limitations. The scope of these indemnities varies, but, in some instances, includes indemnification for damages and expenses (including reasonable attorneys’ fees). There have been no amounts accrued in respect of the indemnification provisions through December 31, 2021.
Purchase Commitments
As of December 31, 2021, the Company had approximately $144.9 million of commitments to purchase goods and services.
NOTE 19: LEGAL PROCEEDINGS
From time to time, the Company is involved in lawsuits as well as subject to various legal proceedings, claims, threats of litigation, and investigations in the ordinary course of business, including claims of alleged infringement of third-party patents and other intellectual property rights, commercial, employment, and other matters. The Company assesses potential liabilities in connection with each lawsuit and threatened lawsuits and accrues an estimated loss for these loss contingencies if both of the following conditions are met: information available prior to issuance of the financial statements indicates that it is probable that a liability has been incurred at the date of the financial statements and the amount of loss can be reasonably estimated. While certain matters to which the Company is a party specify the damages claimed, such claims may not represent reasonably probable losses. Given the inherent uncertainties of litigation, the ultimate outcome of these matters cannot be predicted at this time, nor can the amount of possible loss or range of loss, if any, be reasonably estimated.
NOTE 20: SUBSEQUENT EVENT
On February 3, 2022, the Board of Directors authorized the Company to repurchase up to $100 million of the Company’s outstanding shares of common stock through February 2025. The Company is authorized to repurchase, from time-to-time, shares of its outstanding common stock through open market purchases and 10b5-1 trading plans, in accordance with applicable rules and regulations, at such time and such prices as management may decide. The program does not obligate the Company to repurchase any specific number of shares and may be discontinued at any time.

Item 9A. | CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures
We maintain “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) under the Exchange Act, that are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.
Based on their evaluation as of the end of the period covered by this Annual Report on Form 10-K, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective.
Management’s Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). Management conducted an assessment of the effectiveness of the Company’s internal control over financial reporting based on the criteria set forth in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the Company’s assessment, management concluded that its internal control over financial reporting was effective as of December 31, 2021.
The Company’s independent registered public accounting firm, Armanino LLP, has audited the effectiveness of the Company’s internal control over financial reporting, as stated in their report which appears in Part II, Item 8 of this Form 10-K.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting during our fourth quarter of fiscal year 2021, which were identified in connection with management’s evaluation required by paragraph (d) of rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
