Manufacturing
Our core competencies are the design, development and marketing of robots. Our manufacturing strategy is to outsource non-core competencies, such as the production of our robots, to third-party entities skilled in manufacturing. By relying on the outsourced manufacture of our robots, we can focus our engineering expertise on the design of robots.robots and associated technologies.
Manufacturing a new product requires a close relationship between our product designers, our operations teams and the manufacturing organizations.contract manufacturer, as well as a range of component and raw materials suppliers as appropriate. Using multiple engineering techniques, our products are introduced to the selected production facility at an early-development stage and the feedback provided by manufacturing is incorporated into the design before tooling is finalized and mass production begins. As a result, we believe that we can significantly reduce the time required to move a product from its design phase to mass production deliveries, with improved quality and yields. Once a new product has been introduced, we focus on executing a multi-year plan to improve its profitability through a combination of higher production volume and cost-optimization initiatives.

Under our agreements with our contract manufacturers, the manufacturers supply us with specified quantities of products that align with demand forecasts that we establish based upon historical trends and analysis from our sales and product management functions. We believe that we have taken steps to diversify our manufacturing so that overall volumes are relatively well balanced across our multiple contract manufacturers and a substantial majority of volume is dual sourced. We expect our production processes will give us the capacity to produce up to 37,000 robots a day in 2022, helping us to meet demand for peak seasons and provide us with additional greater geographical diversity and flexibility to respond to ever-changing market conditions.
We outsource the manufacturing of our consumer products to fourmultiple contract manufacturers eachwith plants in Southern China and Malaysia. During 2021, we continued to scale production in Malaysia by qualifying additional contract manufacturers. The COVID-19 pandemic has affected and delayed our effort to fully diversify our supply chain into Malaysia during fiscal 2021. In fiscal 2022, we plan to continue to scale and expand production in Malaysia with the goal of which manufactureshaving the majority of our robots at a single plantU.S. volume produced in Malaysia so that we can substantially reduce our exposure to current U.S. tariffs in 2023, and mitigate the geopolitical risks associated with concentrating production solely in China.

Our research and development is conducted by teams dedicated to particular projects. Our research and development effortsprojects, which are primarily located at our headquarters in Bedford, Massachusetts and our office in Pasadena, California.
Competition
The market for robots, including floor cleaning robots, is highly competitive, rapidly evolving and subject to changing technologies, shifting customer needs and expectations, with an increasing number of competitor companies and products. As the likely increased introductionperformance, functionality and features of newour floor cleaning robots have advanced, we believe that consumers are increasingly willing to consider our products as replacements for their traditional vacuum cleaners and wet floor cleaning products. A number of established companies have developed or are developing robots that will compete directly with our product offerings, and many of our competitors have significantly more financial and other resources than we possess. Our robot cleaning competitors include consumer electronics and consumer appliance companies such as Samsung, LG, Panasonic, Xiaomi, Cecotec, Hitachi, Electrolux, Midea and Shark, traditional floor cleaning brands with robotic offerings such as Dyson, Bissell and Hoover, and firms primarily focused on robotic cleaning such as well as developers of robotEcovacs, Roborock, Neato and iLife. In addition, several competitors market floor cleaning products.

While we believe many of our customers purchase our Roomba floorrobots that consolidate both vacuuming robots and Braava mopping robots asin a supplement to, rather than a replacement for, their traditional vacuum cleaners and wet floor cleaning methods, we do compete in some cases with providers of traditional cleaning products.
single product. We believe that the principal competitive factors in the market for robots include product features, performance for the intended mission, cost of purchase, total cost of system operation and overall perceived value, including maintenance and support, ease of use, integration with existing equipment, quality, reliability, customerbrand and reputation.
The market for air purifiers is also highly competitive with an increasing number of competitors and products along with the potential for emerging technologies to disrupt the marketplace. A number of companies offer air purifiers that compete directly with ours, and many of these competitors possess greater financial strength and better access to other resources than we do. Our air purifier competitors include consumer and industrial appliance and electronics companies such as Honeywell, Dyson, Holmes and Levoit, as well as specialized home health companies that focus extensively on air purification with premium products such as Blue Air, Molekule, Alen Air, Austin Air and IQAir. We believe that the principal competitive factors in the market for air purifiers include the ability to improve air quality by removing a wide range of pollutants, measure

Intellectual Property
We believe that our continued success depends in large part on our proprietary technology, the intellectual skills of our employeestechnical competence and the ability of our employees to continue to innovate. We rely on a combination of patent, copyright, trademark and trade secret laws, as well as confidentiality agreements, to establish and protect our proprietary rights. As part of the sale of our defense and security business, we transferred to the buyerThe ownership of certain of our intellectual property related torights is an important factor in our business. This includes patents, copyrights, trademarks, service marks, trade dress and other forms of intellectual property rights in the defenseUnited States and security business, includinga number of foreign countries. We currently hold a significant number of patents and have filed numerous additional patent applications and trademarks.
applications. As of December 30, 2017,January 1, 2022, we held 403567 U.S. patents, more than 6501,000 foreign patents, additional design registrations, and have more than 450 patent applications pending worldwide. OurWhile our U.S. patents will beginbegan to expire in 2019.2021, no single intellectual property right is solely responsible for protecting our products. We will continue to file and prosecute patent (or design registration, as applicable) applications when and where appropriate to attempt to protect our rights in our proprietary technologies. We also encourage our employees to continue to invent and develop new technologies so as to maintain our competitiveness in the marketplace. It is possible that our current patents, or patents which we may later acquire, may be successfully challenged or invalidated in whole or in part. It is also possible that we may not obtain issued patents for our pending patent applications or other inventions we seek to protect. In that regard, we sometimes permit certain intellectual property to lapse or go abandoned under appropriate circumstances, and due to uncertainties inherent in prosecuting patent applications, sometimes patent applications are rejected and we subsequently abandon them.circumstances. It is also possible that we may not develop proprietary products or technologies in the future that are patentable, or that any patent issued to us may not provide us with any competitive advantages, or that the patents of others will harm or altogether preclude our ability to do business.
Our registered U.S. trademarks include iRobot and its stylized logo, Roomba, Clean Base, NorthStar, Create, Clean Map, iAdapt, Aware, Home Base, Looj, Braava, Braava jet, AeroForce, AllergenLock, Better Together, PerfectEdge, Corners.

Our marks iRobot, Roomba, Braava, Braava jet, Better Together, Root, Clean Base, Clean Map, Imprint, PerfectEdge, Terra, Virtual Wall, and certain other trademarks, have also been registered in selected foreign countries.
Our means of protecting our proprietary rights may not be adequate, and our competitors may independently develop technology that is similar to ours. Legal protections afford only limited protection for our technology. The laws of many countries do not protect our proprietary rights to as great an extent as do the laws of the United States. Despite our efforts to protect our proprietary rights, unauthorized parties have in the past attempted, and may in the future attempt, to copy aspects of our products or to obtain and use information that we regard as proprietary. In 2017,Some of our competitors seek to compete primarily through aggressive pricing and low-cost structures while infringing on our intellectual property.
On October 15, 2019, we initiated a multi-partypatent infringement lawsuit in federal district court in Massachusetts against SharkNinja Operating LLC and its related entities ("SharkNinja") for infringement of five patents for technology related to robotic vacuum cleaners. In addition, we sought a preliminary injunction against SharkNinja for infringement of three U.S. patents. SharkNinja has in parallel sought declarations of non-infringement of thirteen U.S. patents owned by iRobot. On November 26, 2019, the federal district court in Massachusetts denied iRobot's motion for a preliminary injunction, and the case is currently stayed pending the outcome of one or more appeals from decisions of the U.S. Patent Trial and Appeal Board. On January 28, 2021, we initiated litigation against SharkNinja at the U.S. International Trade Commission ("ITC") as well as in federal district court in Massachusetts based on claims of patent infringement. infringement of five additional U.S. patents related to robotic vacuum cleaners. The trial began in January 2022.
There is no guarantee that we will prevail on these or other patent infringement claims against third parties. Third parties may also design around our proprietary rights, which may render our protected products less valuable, if the design around is favorably received in the marketplace. In addition, if any of our products or the technology underlying our products is covered by third-party patents or other intellectual property rights, we could be subject to various legal actions. We cannot assure you that our products do not infringe patents held by others or that they will not in the future. We have received in the past communications from third parties relating to technologies used in our various robot products that have alleged infringement of patents or violation of other intellectual property rights. Some of these allegations have resulted in actions filed against iRobot in foreign jurisdictions. In response to these communications, we have contacted these third parties to convey our good faith belief that we do not infringe the patents in question or otherwise violate those parties' rights. Although there haveWhere an action has been no additional actions or communications with respect to these allegations,filed, we will defend iRobot against the allegations. We cannot assure you that we will not receive further correspondence from these parties, or not be subject to additional allegations of infringement from others.others, and cannot assure you that iRobot will prevail in any ongoing or

subsequently filed actions. Litigation may be necessary to enforce our 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, misappropriation, or other claims. Any such litigation could result in substantial costs and diversion of our resources. Moreover, any settlement of or adverse judgment resulting from such litigation could require us to obtain a license to continue to use the technology that is the subject of the claim, or otherwise restrict or prohibit our use of the technology. Any required licenses may not be available to us on acceptable terms, if at all. If we attempt to design around the technology at issue or to find another provider of suitable alternative technology to permit us to continue offering applicable software or product solutions, our continued supply of software or product solutions could be disrupted or our introduction of new or enhanced software or products could be significantly delayed.

Seasonality
Historically, we have experienced higher revenue in the second half of the year compared to the first half of the year due in large part to seasonal holiday demand. In 2017, 2016For the years ended January 1, 2022, January 2, 2021 and 2015,December 28, 2019, our second-half consumer product revenue represented 60.2%57.3%, 57.5%67.0% and 50.5%59.0% of our annual consumer product revenue, respectively. We have also experienced higher selling and marketing expenses in the second half of the year compared to the first half of the year due to increased marketing campaigns to support seasonal holiday demand. In fiscal years 2021, 2020 and 2019, our selling and marketing expense in the second half of the year represented 56.0%, 67.7% and 58.9% of our selling and marketing expense for full fiscal year, respectively. We expect that the majority of our revenue and selling and marketing expenses will continue to be generated in the second half of any given fiscal year unless or until we successfully introduce new products that have potential to generate stronger sales during the first half of the year.
Regulations
Our business requires compliance with a variety of laws and regulations in the United States and abroad regarding privacy, data protection, and data security. In particular, we are subject to numerous U.S. federal, state, and local laws and regulations and foreign laws and regulations regarding privacy and the collection, sharing, use, processing, disclosure, and protection of personal information and other user data.data, including the General Data Protection Regulation ("GDPR") and California Consumer Privacy Act. In addition, the global nature of our business operations also creates various domestic and foreign regulatory challenges and subjectsubjects us to laws and regulations such as the U.S. Foreign Corrupt Practices Act, or FCPA, the U.K. Bribery Act, and similar anti-bribery and anti-corruption laws in other jurisdictions, and ourjurisdictions. Our products are alsomay be subject to U.S. export controls, including the U.S.United States Department of Commerce’s Export Administration Regulations, and various economic and trade sanctions regulations established by the Treasury Department’s Office of Foreign Assets Controls.Controls and trade policies and tariffs established by the governments of the United States, China and other jurisdictions where we do business.
The laws in each of these areas - in particular those related to data privacy - are continually changing and evolving in unpredictable ways. New laws and regulations in any of these areas, as well as compliance with these laws (and their derivatives) may have an adverse effect on our business. If we fail to comply with these laws, we may be subject to significant liabilities and other penalties.
We are also subject to international and U.S. federal, state, and local laws and regulations designed to protect the environment, regulate energy efficiency and to regulate the discharge of materials into the environment. We believe that our policies, practices, and procedures are properly designed to prevent unreasonable risk of environmental damage and associated financial liability. To date, environmental control regulations have not had a significant adverse effect on our overall operations.
Prior to our divestiture of the defense and security business unit in April 2016, we were subject to various government regulations, including various U.S. federal government regulations as a contractor and subcontractor to the U.S. federal government. We continue to remain subject to certain of these regulations only as they pertain to matters related to our operation of the defense and security business unit prior to our completion of the sale of this business.

Additional risks and uncertainties not presently known to us, which we currently deem immaterial or which are similar to those faced by other companies in our industry or business in general, may also impair our business operations. If any of the following risks or uncertainties actually occurs, our business, financial condition and operating results would likely suffer.
Risks Related to our Business and Industry
We face intense competition from other providers of robots, including diversified technology providers, as well as competition from providers offering alternative products, which could negatively impact our results of operations and cause our market share to decline.
A number of companies have developed or are developing robots that will compete directly with our product offerings. Our competition includes established, well-known sellers of floor cleaning robots such as Ecovacs, SharkNinja, Samsung, Roborock, as well as new market entrants. Many current and potential competitors are larger in size and more broadly diversified with substantially greater financial, marketing, research and manufacturing resources than we possess, and there can be no assurance that our current and future competitors will not be more successful than us. We also face competition from manufacturers of lower-cost devices, which has, and may continue to, further drive down the average selling price in the marketplace for floor cleaning products.Moreover, while we believe many of our customers purchase our floor vacuuming robots as a supplement to, rather than a replacement for, their traditional vacuum cleaners, we also compete with providers of traditional vacuum cleaners.
The global market for robots is highly competitive, rapidly evolving and subject to changing technologies, shifting customer needs and expectations and the likely increased introduction of new products. Our ability to remain competitive will depend to a great extent upon our ongoing performance in the areas of product development, operating efficiency and customer support.
We expect that competition will continue to intensify as additional competitors enter the market and current competitors expand their product lines. Companies competing with us have, and may continue to, introduce products that are competitively priced, have increased performance or functionality, or incorporate technological advances that we have not yet developed or implemented. Increased competitive pressure has resulted and will continue to result in a loss of sales or market share or cause us to lower prices for our products, any of which would harm our business and operating results.
Many of our competitors have demonstrated an ability to rapidly replicate new features and innovations that we have introduced into the market, and therefore are able to offer a comparable suite of product offerings at lower prices. In addition, some of our competitors aggressively discount their products and services in order to gain market share, which has resulted in pricing pressures, reduced profit margins and lost market share. In addition, new products may have lower selling prices or higher costs than legacy products, which could negatively impact our gross margins and operating results.
We cannot assure you that our products will continue to compete favorably or that we will be successful in the face of increasing competition from new products and enhancements introduced by existing competitors or new companies entering the markets in which we provide products. Our failure to compete successfully could cause our revenue and market share to decline, which would negatively impact our results of operations and financial condition.
We operate in an emerging market, which makes it difficult to evaluate our business and future prospects.
Robots represent a new and emerging market. Accordingly, our business and future prospects are difficult to evaluate. We cannot accurately predict the extent to which demand for consumerfloor cleaning robots will increase, if at all. You should consider the challenges, risks and uncertainties frequently encountered by companies using new and unproven business models in rapidly evolving markets. These challenges include our ability to:

generate sufficient revenue and gross margin to maintain profitability;
acquire and maintain market share in our consumer market;
attract and retain customers of our consumer robots;
attract and retain engineers and other highly-qualified personnel; and

expand our product offerings beyond our existing robots.
If we fail to successfully address these and other challenges, risks and uncertainties, our business, results of operations and financial condition would be materially harmed.
Designing new robotic products is complex and requires significant resources, and our ability to remain competitive requires significant continued investment in tools, processes and talent.
To remain competitive, we must increase investment in developing tools and processes to improve the speed at which we are able to develop competitive products, including significant investment in developing a reusable software architecture across multiple product platforms. The development of a reusable software architecture requires the expenditure of significant resources that may not result in the designed efficiencies. Our inability to reduce the cost to develop new products or product variants may substantially impact our ability to offer products that compete favorably.
We depend on the experience and expertise of our senior management team and key technical employees, and the loss of any key employee may impair our ability to operate effectively.
Our success depends upon the continued services of our senior management team and key technical employees. Each of our executive officers, key technical personnel and other employees could terminate his or her relationship with us at any time. The loss of any member of our senior management team might significantly delay or prevent the achievement of our business objectives and could materially harm our business and customer relationships. In addition, because of the highly technical nature of our robots, the loss of any significant number of our existing engineering and project management personnel could have a material adverse effect on our business and operating results. In addition, increased turnover, particularly on the senior management team, with insufficient development of leadership talent and succession plans, could diminish employee confidence and increase risks for retaining key employees.
If we are unable to attract and retain additional skilled personnel, we may be unable to grow our business.
To execute our growth plan, we must attract and retain additional, highly-qualified personnel. Competition for hiring these employees is intense, especially with regard to engineers with high levels of experience in designing, developing and integrating robots and engineers with expertise in artificial intelligence, machine learning, data science and cloud applications. Many of the companies with which we compete for hiring experienced employees have greater resources than we have. If we fail to attract new technical personnel or fail to retain and motivate our current employees, our business and future growth prospects could be severely harmed.
In addition, we have experienced increased employee turnover as a result of general market conditions and the on-going "great resignation" occurring throughout the U.S. economy, and we expect to continue to experience increased employee turnover in the future. New hires require significant training and, in most cases, take significant time before they achieve full productivity. New employees may not become as productive as we expect, and we may be unable to hire or retain significant numbers of qualified individuals. Moreover, we may be forced to adjust salaries or other compensation in order to retain key talent. If our retention efforts are not successful or our team member turnover rate continues to increase in the future, our business, results of operations and financial condition could be materially and adversely affected.
Our business has been, and will continue to be, adversely affected by the ongoing coronavirus pandemic.
The outbreak of the novel coronavirus has evolved into a global pandemic. The coronavirus has already directly and indirectly impacted our business and operating results but the full extent of its impact will depend on future developments that are uncertain and cannot be accurately predicted, including new information that may emerge concerning the coronavirus, including any variants such as the Omicron variant, and the actions to contain the coronavirus or treat its impact, among others.The ultimate impact of the current pandemic, or any other health epidemic, is highly uncertain and subject to change not only with the spread of the disease, but also with the scope and timing of governmental, regulatory, fiscal, monetary and public health responses.
As the coronavirus continues to spread, our business operations could be further disrupted or delayed. The pandemic has already resulted in, and may continue to result in, work stoppages, slowdowns and delays, travel restrictions, event cancellation, and other factors that cause an increase in costs or order cancellations, reductions or delays. For example, our manufacturing supply chain has been and may continue to be adversely affected with production delays or limited manufacturing volumes associated with factory shutdowns or reduced numbers of workers or working hours in the factories, limits on component supplies and diminished capability to implement engineering and design changes in a timely manner. Specifically, travel restrictions have prevented, and may continue to prevent, significant progress in supply chain diversification efforts in Malaysia, which may have a material impact on our ability to mitigate the impact of certain tariffs. In addition, quarantines, stay at home orders and other travel limitations (whether voluntary or required) impede our employees’ ability to efficiently conduct research and development activities or oversee manufacturing activities, which has, and may continue to, slow innovation, lead to higher costs or both. For example, we have already experienced an increase in freight costs and a delay in our supply chain

diversification efforts. Further, if the spread of the coronavirus pandemic continues and our operations continue to be adversely impacted, we risk a delay, default, violation and/or non-compliance under existing agreements.
The spread of the coronavirus, which has caused a broad impact globally, including restrictions on travel and quarantine policies put into place by businesses and governments, has had and may continue to have a material economic effect on our business. For example, the pandemic and related measures taken to limit the spread of disease has resulted in higher unemployment and greater economic uncertainty, which may adversely affect consumer purchasing behavior. Further, retail store closures, whether temporary or permanent, as well as limited operating hours and restrictions on foot traffic and maximum capacities in stores may continue to adversely affect sales of our products. Certain retailers, who we rely on for a significant portion of our revenue, have begun, and may continue, to unilaterally stretch payables to us that may increase our accounts receivable, strain our liquidity, and increase the likelihood of our failure to collect on product previously sold.
While the potential economic impact and the duration of the pandemic may be difficult to assess or predict, it has already caused, and is likely to result in further, significant disruption of global financial markets. In addition, a recession, depression or other sustained adverse market event resulting from the spread of the coronavirus could materially and adversely affect our business, our access to needed capital and liquidity, and the value of our common stock. We do not yet know the full extent of potential delays or impacts on our business, our industry or the global economy as a whole. Additionally, while significant efforts are underway to slow the spread of the disease, increase testing and develop and distribute vaccines and therapeutics, it is unclear when or whether progress in any of those areas will translate into an economic recovery that will restore consumer confidence and minimize disruptions to our operations. Accordingly, given that the potential of these effects of the current pandemic on our operations has been and will likely continue to be material, we will continue to monitor the situation closely.
Surges in demand impacting the cost and availability of transportation have had, and we expect will continue to have, an adverse impact on our business, financial condition and results of operations.
Surges in demand related to COVID-19, as well as other factors, have continued to strain the global supply chain network, which has resulted in carrier-imposed capacity restrictions, carrier delays, and longer lead times. Demand for Chinese imports has caused shipment receiving and unloading backlogs at many U.S. ports that have been unable to keep pace with unprecedented inbound container volume. The situation has been further exacerbated by COVID-19 illness and protocols at many port locations. Due to the backlog and increasing trade imbalance with China, many shipping containers are not being sent back to China, or are being sent to China empty. With continued increases in demand for containers, limited supply and freight vendors bearing the cost of shipping empty containers, the market cost of inbound freight has increased by several multiples compared to historical averages. To the extent that transportation costs and interruptions continue, we may face increased pressure on gross margins, product delivery delays and an inability to fulfill orders for our products.
If we are not successful in expanding our direct-to-consumer sales channel by driving consumer traffic and consumer purchases through our website, our business and results of operations could be harmed.
We are currently investing in our direct-to-consumer sales channel, primarily through our website and mobile app, and our future growth relies in part on our ability to attract consumers to this channel, which requires significant expenditures in marketing, software development and infrastructure. If we are unable to drive traffic to, and increase sales through, our website and mobile app, our business and results of operations could be harmed. The success of direct-to-consumer sales is subject to risks associated with e-commerce, many of which are outside of our control. Our inability to adequately respond to these risks and uncertainties or to successfully maintain and expand our direct-to-consumer business via our website may have an adverse impact on our results of operations.
Our success depends solelynearly entirely on our consumer robots, and our sales growth and operating results would be negatively impacted if we are unable to enhance our current consumer robots or develop new consumer robots at competitive prices or in a timely manner, or if the consumer robot market does not achieve broad market acceptance.
For the years ended December 30, 2017, December 31, 2016 and January 2, 2016, we derived 100.0%, 99.3%, and 90.7% ofWe primarily derive our total revenue from our consumer robots, respectively.robot sales. For the foreseeable future, we expect that our revenue will be derived solelynearly entirely from sales of consumer robots in general, and home floor care products in particular.products. Accordingly, our future success depends upon our ability to further penetrate the consumer home care market, to enhance our current consumer products and to develop and introduce new consumer products offering enhanced performance and functionality at competitive prices. The development and application of new technologies involves time, substantial costs and risks. Our inability to achieve significant sales of our newly introduced robots, or to enhance, develop and introduce other products in a timely manner, or at all, would materially harm our sales growth and operating results.
Even if consumer robots gain wide market acceptance, our robots may not adequately address market requirements and may not continue to gain market acceptance. If robots generally, or our robots specifically, do not gain wide market acceptance, we may not be able to achieve our anticipated level of growth, and our revenue and results of operations would suffer.
We face intense competition from other providers

Any efforts to expand our product offerings beyond our current markets or to develop new products may not succeed, which could negatively impact our results ofoperating results.
Efforts to expand our product offerings beyond our current markets are limited and those efforts may not succeed and may divert management resources from existing operations and causerequire us to commit significant financial resources to an unproven business, either of which could significantly impair our operating results. Any new product that we develop may not be introduced in a timely or cost-effective manner, may contain defects, or may not achieve the market shareacceptance necessary to decline.generate sufficient revenue. Moreover, efforts to expand beyond our existing markets may never result in new products that achieve market acceptance, create additional revenue or become profitable.
AOn November 15, 2021, we acquired Aeris Cleantec AG, a fast-growing provider of premium air purifiers. This acquisition represents our first major expansion of product offerings beyond consumer robotics. Air purifiers represent a new market segment for us and is subject to intense competition.
Our success in the air purifier market will depend on a number of companiesfactors including our ability to develop innovative solutions, integrate those solutions into our home ecosystem, and market and sell those solutions to our existing and new customers. Establishing a new market segment will require significant investment in R&D and sales & marketing in the near term. These investments may not be successful, and our revenue and profitability may suffer.
If the air purifier business – or any other business we acquire – does not perform as expected or we are unable to effectively integrate the acquired business into our operations or achieve the expected synergies of the acquisition, our operating results could be harmed. Expansion into new market segments involve risks and uncertainties, including, among other things, potential distraction of management from our core robotic floorcare business, greater than expected liabilities and expenses, inadequate return on capital, and unidentified issues not discovered in our investigations and evaluations of those acquisitions.
We spend significant amounts on advertising and other marketing campaigns, which may not be successful or cost effective.
We spend significant amounts on advertising and other marketing campaigns, such as television, print advertising, and social media, as well as increased promotional activities, to acquire new customers, and we expect our marketing expenses to increase in the future as we continue to spend significant amounts to increase awareness of our consumer robot products. For the years ended January 1, 2022, January 2, 2021 and December 28, 2019, sales and marketing expenses were $289.8 million, $265.5 million and $231.5 million, respectively, representing approximately 18.5%, 18.6%, and 19.1% of our revenue, respectively. While we seek to structure our advertising campaigns in the manner that we believe is most likely to encourage people to purchase our products, we may fail to identify advertising opportunities that satisfy our anticipated return on advertising spend as we scale our investments in marketing or to fully understand or estimate the conditions and behaviors that drive customer behavior. If any of our advertising campaigns prove less successful than anticipated in attracting customers, we may not be able to recover our advertising spend, and our revenue may fail to meet market expectations, either of which could have developed or are developing robots that will compete directly withan adverse effect on our product offerings. Many current and potential competitors have substantially greater financial, marketing, research and manufacturing resources than we possess, and therebusiness. There can be no assurance that our currentadvertising and future competitorsother marketing efforts will not be more successful than us. We also face competition from manufacturers of lower-cost devices, which may drive down the average selling priceresult in the marketplace for floor cleaning products. Moreover, while we believe manyincreased sales of our customers purchase our floor vacuuming robots as a supplement to, rather than a replacement for, their traditional vacuum cleaners, we also compete in some cases with providers of traditional vacuum cleaners.
The global market for robots is highly competitive, rapidly evolving and subject to changing technologies, shifting customer needs and expectations and the likely increased introduction of new products. Our ability to remain competitive will depend to a great extent upon our ongoing performance in the areas of product development and customer support.
In the event that the robot market expands further, we expect that competition will intensify as additional competitors enter the market and current competitors expand their product lines. Companies competing with us may introduce products that are competitively priced, have increased performance or functionality, or incorporate technological advances that we have not yet developed or implemented. Increased competitive pressure could result in a loss of sales or market share or cause us to lower prices for our products, any of which would harm our business and operating results.
Some of our competitors may aggressively discount their products and services in order to gain market share, which could result in pricing pressures, reduced profit margins, lost market share, or a failure to grow market share for us. In addition, new products may have lower selling prices or higher costs than legacy products, which could negatively impact our gross margins and operating results. 
We cannot assure you that our products will continue to compete favorably or that we will be successful in the face of increasing competition from new products and enhancements introduced by existing competitors or new companies entering the markets in which we provide products. Our failure to compete successfully could cause our revenue and market share to decline, which would negatively impact our results of operations and financial condition.

If we fail to enhance our brand, our ability to expand our customer base will be impaired and our operating results may suffer.
We believe that developing and maintaining awareness of the iRobot brand is critical to achieving widespread acceptance of our existing and future products and is an important element in attracting new customers. Furthermore, we expect the importance of global brand recognition to increase as competition develops.increases. If customers do not perceive our products to be of high quality, our brand and reputation could be harmed, which could adversely impact our financial results. In addition, brand promotion efforts may not yield significant revenue or increased revenue sufficient to offset the additional expenses incurred in building our brand. Maintaining, protecting, and enhancing our brand may require us to make substantial investments, and these investments may not be successful. If we fail to successfully maintain, promote, and position our brand and protect our reputation, or if we incur significant expenses in this effort, our business, financial condition and operating results may be adversely affected.
Any efforts to expand our product offerings beyond our current markets may not succeed, which could negatively impact our operating results.

Efforts to expand our product offerings beyond our current markets may not succeed and may divert management resources from existing operations and require us to commit significant financial resources to an unproven business, either of which could significantly impair our operating results. Moreover, efforts to expand beyond our existing markets may never result in new products that achieve market acceptance, create additional revenue or become profitable.
Our financial results often vary significantly from quarter-to-quarter due to a number of factors, which may lead to volatility in our stock price.
Our quarterly revenue and other operating results have varied in the past and are likely to continue to vary significantly from quarter-to-quarter in the future. These fluctuations may be due to numerous factors including:
the size, timing and mix of orders from retail stores and distributors for our consumer robots;
the mix of products that we sell in the period;
disruption of supply of our products from our manufacturers;
disruptionsRisks Related to our supply chain due to inclement weather, labor disruptions or other factors beyond our control;
seasonality in the sales of our products;
the timing of new product introductions;
unanticipated costs incurred in the introduction of new products;
costsDependence on Third Parties and availability of labor and raw materials;
costs of freight;
changes in our rate of returns for our consumer products;
our ability to introduce new products and enhancements to our existing products on a timely basis; and
warranty costs associated with our consumer products.
We cannot be certain that our revenues will grow at rates that will allow us to maintain profitability during every fiscal quarter, or even every fiscal year. We base our current and future expense levels on our internal operating plans and sales forecasts, including forecasts of holiday sales for our consumer products. A significant portion of our operating expenses, such as research and development expenses, certain marketing and promotional expenses and employee wages and salaries, do not vary directly with sales and are difficult to adjust in the short term. As a result, if sales for a quarter are below our expectations, we might not be able to reduce operating expenses for that quarter. Accordingly, a sales shortfall during a fiscal quarter, and in particular the fourth quarter of a fiscal year, could have a disproportionate effect on our operating results for that quarter or that year. Because of quarterly fluctuations, we believe that quarter-to-quarter comparisons of our operating results are not necessarily meaningful. Moreover, our operating results may not meet expectations of equity research analysts or investors. If this occurs, the trading price of our common stock could fall substantially either suddenly or over time.Distribution Channels
We depend on single sourcea limited number of manufacturers, and our reputation and results of operations would be harmed if these manufacturers fail to meet our requirements.
We currently depend largely on several single source contracta limited number of manufacturers, employing a dual-source strategy to mitigate potential manufacturing disruptions, and we have safety stock strategies for the manufacture of certainlow-volume products that are not dual sourced. The majority of our products. All contract manufacturersmanufacturing locations for our current robots are currently located in China.China and we added additional manufacturing capacity in Malaysia in late 2019, and we have continued to expand production in Malaysia. Our efforts to diversify manufacturing outside of China has been, and may continue to be, materially impacted as a result of COVID-19 and related travel restrictions. These manufacturers manage the supply substantiallychain for all of the raw materials and provide all facilities and labor required to manufacture our products. If these companies were to terminate their arrangements with us or fail to provide the required capacity and quality on a timely basis, wethere would be unable to manufacturea disruption in manufacturing our products until replacement contract manufacturing services could be obtained or volume transferred to an

alternative manufacturing partner, each of which is a costly and time-consuming process. We cannot assure you that we would be able to establish alternative manufacturing arrangements on acceptable terms or in a timely manner.
We are dependent on a limited number of suppliers for various components used in our products, and we may from time to time have sole source suppliers. The cost, quality and availability of these components are essential to the successful production and sale of our products. We are subject to the risk of, and have already experienced, industry-wide shortages, price fluctuations and long lead times in the supply of these components and other materials, which risk may be increased as a result of COVID-19. If the supply of these components were to be delayed or constrained, or if one or more of our main suppliers were to go out of business, alternative sources or suppliers may not be available on acceptable terms or at all. In the event that any of our suppliers were to discontinue production of our key product components, developing alternate sources of supply for these components would be time consuming, difficult and costly. In the event we are unable to obtain components in sufficient quantities on a timely basis and on commercially reasonable terms, our ability to sell our products in order to meet market demand would be affected and could materially and adversely affect our brand, image, business prospects, financial condition and operating results.
Our reliance on these contract manufacturers involves certain risks, including the following:
lack of direct control over production capacity and delivery schedules;
lack of direct control over quality assurance, manufacturing yields and production costs;
lack of enforceable contractual provisions over the production and costs of consumer products;
risk of loss of inventory while in transit;
risks associated with international commerce, including unexpected changes in legal and regulatory requirements, changes in tariffs and trade policies, risks associated with the protection of intellectual property and political and economic instability; and
risks that our attempts to add additional manufacturing resources may be significantly delayed and thereby create disruptions in production of our products.
Any interruption in the manufacture of our products would be likely to result in delays in shipment, lost sales and revenue and damage to our reputation in the market, all of which would harm our business and results of operations. In addition, whilebecause our contract obligationspurchase contracts with our contract manufacturers in Chinasuppliers are typically denominated in U.S. dollars, changes in currency exchange rates couldmay impact our suppliers who operate in local currency, which may cause our suppliers to seek price concessions on future orders.
If critical components of our products that we currently purchase from a small number of suppliers become unavailable, we may incur delays in shipment, which could damage our business.
We and increase our prices.outsourced manufacturers obtain hardware components, various subsystems, raw materials and batteries from a limited group of suppliers, some of which are sole suppliers. We do not have long-term agreements with these suppliers obligating them to continue to sell components or products to us. If we or our outsourced manufacturers are unable to obtain components from third-party suppliers in the quantities and of the quality that we require, on a timely basis and at acceptable prices, we may not be able to deliver our products on a timely or cost-effective basis to our customers, which could cause customers to terminate their contracts with us, reduce our gross margin and seriously harm our business, results of operations and financial condition. Moreover, if any of our suppliers become financially unstable, we may have to find new suppliers. It may take several months to locate alternative suppliers, if required, or to re-tool our products to accommodate components from

different suppliers. We may experience significant delays in manufacturing and shipping our products to customers and incur additional development, manufacturing and other costs to establish alternative sources of supply if we lose any of these sources. We cannot predict if we will be able to obtain replacement components within the time frames that we require at an affordable cost, or at all.
Conflicts with our channel and distribution partners could harm our business and operating results.
The expansion of our direct-to-consumer channel could alienate some of our channel partners and cause a reduction in product sales from these partners. Channel partners may perceive themselves to be at a disadvantage based on the direct-to-consumer sales offered through our website. Due to these and other factors, conflicts in our sales channels could arise and cause channel partners to divert resources away from the promotion and sale of our products. Any of these situations could adversely impact our business and results of operations.
If we fail to maintain or increase consumer robot sales through our distribution channels, our operating results would be negatively impacted.
We do not have long-term contracts regarding purchase volumes with any of our retail partners. As a result, purchases generally occur on an order-by-order basis, and the relationships, as well as particular orders, can generally be terminated or otherwise materially changed at any time prior to delivery, by our retail partners. A decision by a major retail partner, whether motivated by competitive considerations, financial difficulties, economic conditions or otherwise, to decrease its purchases from us, to reduce the shelf space for our products or to change its manner of doing business with us could significantly damage our consumer product sales and negatively impact our business, financial condition and results of operations. In addition, during recent years, various retailers, including some of our partners, have experienced significant changes and difficulties, including consolidation of ownership, increased centralization of purchasing decisions, restructuring, bankruptcies and liquidations. These and other financial problems of some of our retailers increase the risk of extending credit to these retailers. A significant adverse change in a retail partner relationship with us or in a retail partner’s financial position could cause us to limit or discontinue business with that partner, require us to assume more credit risk relating to that partner’s receivables or limit our ability to collect amounts related to previous purchases by that partner, all of which could harm our business and financial condition. Disruption of the iRobot on-line store could also decrease our consumer robot sales.
If critical componentsRisks Related to our Legal and Regulatory Environment
Significant developments in U.S. trade policies have had, and we expect will continue to have, a material adverse effect on our business, financial condition and results of operations.
The U.S. government has indicated its intent to alter its approach to international trade policy and in some cases to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements and treaties with foreign countries. Effective September 24, 2018, the U.S. government implemented a 10% tariff on certain goods imported from China, which include the majority of those imported by the Company. These tariffs were increased to 25% on May 10, 2019 and were slated to further increase to 30% in October 2019 until a last-minute interim deal was reached between the United States and China. Although the United States and China signed a new trade agreement in January 2020, most of the previously-implemented tariffs on goods imported from China remain in place (including the tariffs described above), and uncertainty remains as to the short-term and long-term future of economic relations between the United States and China.
From September 2018 until April 2020, our Roomba products were subject to Section 301 tariffs. On April 24, 2020, we were granted a temporary exclusion from Section 301 List 3 tariffs by the United States Trade Representative ("USTR"). This exclusion, as extended in August 2020, eliminated the 25% tariff on Roomba products until December 31, 2020 and entitled us to a refund of $57.0 million in tariffs paid since the date the Section 301 List 3 tariffs were imposed.
Effective as of January 1, 2021, the 25% Section 301 tariff again applies to our Roomba products imported from China.Although we have begun relocating a meaningful portion of our supply chain from China to Malaysia, we again face compression on our margin on products that we currently purchase from a small number of suppliers become unavailable, wesold and pricing pressures on our products. The already-implemented, and any additional or increased, tariffs have caused, and may incur delays in shipment, which could damage our business.
We and our outsourced manufacturers obtain hardware components, various subsystems, raw materials and batteries from a limited group of suppliers, some of which are sole suppliers. We do not have any long-term agreements with these suppliers obligating them to continue to sell components or products to us. If we or our outsourced manufacturers are unable to obtain components from third-party suppliers in the quantities and of the quality that we require, on a timely basis and at acceptablefuture cause, us to further increase prices we may not be able to deliver our products on a timely or cost-effective basis to our customers which we believe has reduced, and in the future may reduce, demand for our products.
On October 4, 2021, the USTR announced its decision to establish a new process for importers to apply for exclusions from Section 301 tariffs in 549 product categories, including robotic vacuum cleaners. Beginning October 12, 2021, the USTR started accepting comments on whether or not reinstating certain tariff exclusions will impact or result in severe economic harm to companies or other interests of the United States. On October 21, 2021, we submitted comments related to the continued application of tariffs on robotic vacuum cleaning products. We cannot say definitively when, or even if, iRobot will be granted additional tariff relief on our products still manufactured in China, nor can we guarantee the terms upon which any tariff relief ultimately may be granted. In addition, our new air purification products are also subject to 25% Section 301 tariffs. We did not submit comments related to the continued application of tariffs on certain air purification products; however, a number of
17

Table of Contents
importers did submit such comments, and we believe any grant of tariff relief would also likely extend to our importation of air purification products.
These tariffs, and other governmental action relating to international trade agreements or policies, have directly or indirectly adversely impacted demand for our products, our costs, customers, suppliers, distributors, resellers and/or the U.S. economy or certain sectors thereof and, as a result, have adversely impacted, and we expect will continue to adversely impact, our business, financial condition and results of operations. It remains unclear what the U.S. or foreign governments will or will not do with respect to tariffs, international trade agreements and policies on a short-term or long-term basis. We cannot predict future trade policy, whether exclusions will be reinstated, or the terms of any renegotiated trade agreements and their impacts on our business. The adoption and expansion of trade restrictions, the occurrence of a trade war, or other governmental action related to tariffs or trade agreements or policies has the potential to further adversely impact demand for our products, our costs, our customers, our suppliers, and the U.S. economy, which in turn could cause customersfurther adversely impact our business, financial condition and results of operations.
In response to terminate their contractsinternational trade policy, as well as other risks associated with us, reduceconcentrated manufacturing in China, we have begun relocating a meaningful portion of our gross marginsupply chain from China to Malaysia. Such relocation activities increase costs and seriously harmrisks associated with establishing new manufacturing facilities.

Additionally, disruptions in credit markets may have to find new suppliers. It may take several months to locate alternative suppliers, if required, or to re-tool our products to accommodate components from different suppliers. We may experience significant delays in manufacturingmaterially limit consumer credit availability and shipping our products to customers and incur additional development, manufacturing and other costs to establish alternative sources of supply if we lose any of these sources. We cannot predict if we will be able to obtain replacement components within the time frames that we require at an affordable cost, or at all.
Cybersecurity risks could adversely affect our business and disrupt our operations.
The threats to network and data security are increasingly diverse and sophisticated. Despite our efforts and processes to prevent breaches, our devices, as well as our servers, computer systems, and those of third parties that we use in our operations are vulnerable to cybersecurity risks, including cyber attacks such as viruses and worms, phishing attacks, denial-of-service attacks, and similar disruptions from unauthorized tampering with our servers and computer systems or those of third parties that we use in our operations, which could lead to interruptions, delays, loss of critical data, and loss of consumer confidence. In addition, we may be the target of email scams that attempt to acquire sensitive information or company assets. Despite our

efforts to create security barriers to such threats, we may not be able to entirely mitigate these risks. Any cyber attack that attempts to obtain our data and assets, disrupt our service, or otherwise access our systems, or those of third parties we use, if successful, could adversely affect our business, operating results, and financial condition, be expensive to remedy, and damage our reputation.
If we suffer data breaches involving the designs, schematics or source code for our products, our brand, business and financial results could be adversely affected.
We attempt to securely store our designs, schematics and source code for our products as they are created. A breach, whether physical, electronic or otherwise, of the systems on which this sensitive data is stored could lead to damage or piracyrestrict credit availability of our products. If we orretail customers, which would also impact purchases of our partners are subject to data security breaches, we may have a lossconsumer robots. Any reduction in sales of our consumer robots, resulting from reductions in consumer spending or increased costs arising fromcontinued disruption in the restorationavailability of credit to retailers or implementation of additional security measures, either of whichconsumers, could materially and adversely affect our brand, business, results of operations and financial results.condition.
Because we are an increasingly global business that in the years ended January 1, 2022, January 2, 2021 and December 28, 2019 generated approximately 51.8%, 47.9% and 50.3%, respectively, of our total revenue from sales to customers outside of the United States, we are subject to a number of additional risks including foreign currency fluctuations. These foreign currency fluctuations may make our products more expensive to our distributors and end customers, which in turn may impact sales directly or the ability or willingness of our partners to invest in growing product demand.
Our primary exposure to movements in foreign currency exchange rates relates to non-U.S. dollar denominated sales and operating expenses worldwide. Weakening of foreign currencies relative to the U.S. dollar could adversely affect the U.S. dollar value of our foreign currency-denominated sales and earnings, and lead us to raise international pricing, which may reduce demand for our products. In some circumstances, for competitive or other reasons, we may decide not to raise local prices to fully offset the strengthening of the U.S. dollar, or for any other reason, which would adversely affect the U.S. dollar value of our foreign currency denominated sales and earnings. Conversely, a strengthening of foreign currencies relative to the U.S. dollar, while generally beneficial to our foreign currency-denominated sales and earnings, could cause us to reduce international pricing, incur losses on our foreign currency derivative instruments, and incur increased operating expenses, thereby limiting any benefit. Additionally, strengthening of foreign currencies may also increase our cost of product components denominated in those currencies, thus adversely affecting gross margins.
We collect, store, process,use derivative instruments, such as foreign currency forward contracts, to hedge certain exposures to fluctuations in foreign currency exchange rates. The use of such hedging activities may not offset any, or only a portion, of the adverse financial effects of unfavorable movements in foreign exchange rates over the limited time the hedges are in place. In addition, our counterparties may be unable to meet the terms of the agreements. We seek to mitigate this risk by limiting counterparties to major financial institutions and use customer data, including certain personalby spreading the risk across several major financial institutions.
We are subject to a variety of U.S. and robot-specific information, which subjects usforeign laws and regulations that are central to governmental regulation and other legal obligations related to privacy, information security, and data protection, and any security breaches or our actual or perceivedbusiness; our failure to comply with such legal obligationsthese laws and regulations could harm our business.business or our operating results.
Our latest Roomba products, as well as additional productsWe are or may become subject to a variety of laws and regulations in development, collect, store, process,the United States and use certain customer data, whichabroad that involve matters central to our business, including laws and regulations regarding consumer protection, advertising, electronic commerce, intellectual property, manufacturing, anti-bribery and anti-corruption, and economic or other trade prohibitions or sanctions.
The increasingly global nature of our business operations subjects us to governmental regulationdomestic and foreign laws and regulations such as the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act, and similar anti-bribery and anti-corruption laws in other jurisdictions. Our products are also subject to U.S. export controls, including the United States Department of Commerce’s Export Administration Regulations and various economic and trade sanctions regulations established by the Treasury Department’s Office of Foreign Assets Controls. In addition, our recently acquired air purifier business subjects us to additional laws and regulations, such as the Federal Food, Drug, and Cosmetic Act, or FD&C Act, the Federal Insecticide, Fungicide and
18

Rodenticide Act, the U.S. Toxic Substances Control Act of 1976, U.S. Department of Energy Efficiency regulations, and various similar state and foreign country laws and regulations related to health and safety and other legal obligations relatedapplicable laws required to privacy,manufacture, commercialize, sell or distribute air purification products. In the U.S., certain air purifiers intended for medical use are regulated as medical devices and are subject to regulation by the U.S. Food and Drug Administration, or FDA, under the FD&C Act and its implementing regulations. The FDA regulates, among other things, premarket clearance, establishment registration and device listing, manufacturing, packaging, labeling, servicing, recordkeeping, advertising, promotion, distribution, recalls and field actions, post-marketing monitoring and reporting. In order to commercially distribute certain air purifiers, we will be required to submit a premarket notification, or 510(k), to the FDA and obtain 510(k) clearance.
We are also subject to a variety of laws and regulations regarding information security and data protection, and any security breaches or our actual or perceived failure to comply with such legal obligations could harm our business. We collect, store, process, and use personal information and other user data, and we rely on third parties that are not directly under our control to do so as well. If our security measures, some of which are managed by third parties, are breached or fail, unauthorized persons may be able to obtain access to or acquire sensitive user data, which may expose us to a risk of loss, litigation, or regulatory proceedings. Depending on the nature of the information compromised, in the event of a data breach or other unauthorized access to or acquisition of our user data, we may also have obligations to notify users about the incident, and we may need to provide some form of remedy, such as a subscription to a credit monitoring service, for the individuals affected by the incident. In addition, the regulatory environment surrounding information security and privacy is increasingly demanding, with frequent imposition of new and changing requirements.privacy. For example, the European Union's ("EU") General Data Protection Regulation (GDPR), which will become effective in May 2018, imposes("GDPR") and the California Consumer Privacy Act, or new interpretations of existing laws and regulations, impose significant new requirements on how we collect, process and transfer personal data, as well as significant fines for non-compliance. Compliance with changes inThese current and future data privacy and information security laws and standardsregulations may result in significant expense dueimpede our initiatives designed to increased investment in technologydeliver targeting marketing.
Given the increasing number of foreign laws to which we are subject and the developmenthigh level of new operational processes. Moreover,complexity of these laws, there is a growing number of legislative and regulatory bodies have adopted consumer notification requirements in the event of unauthorized access to or acquisition of certain types of personal data. Such breach notification laws continue to evolve andrisk that some provisions may be inconsistent from one jurisdictioninadvertently breached by us or by our subsidiaries, for example through fraudulent or negligent behavior of individual employees, our failure to another. Complyingcomply with certain formal documentation requirements, or otherwise. If we incur liability for noncompliance under these obligations could causelaws or regulations, we may be forced to implement new measures to reduce our exposure to this liability. This may require us to incurexpend substantial costsresources or to discontinue certain products or services, which would negatively affect our business, financial condition, and could increaseoperating results. In addition, any negative publicity surrounding any incident that compromises user data.
Acquisitionsdirected to us as a result of lawsuits, regulatory proceedings, and potential future acquisitions may be difficult to integrate, divertlegislative proposals could harm our brand or otherwise impact the attention of key personnel, disrupt our business, dilute stockholder value and impair our financial results.
As partgrowth of our business strategy, we have recently acquired, and we intend to continue to consider additional acquisitionsbusiness. Any costs incurred as a result of companies, technologies and products that we believecompliance efforts or other liabilities under these laws or regulations could accelerate our ability to compete in our core markets or allow us to enter new markets. For example, in April 2017, we acquired the iRobot-related distribution business of Sales On Demand Corporation (SODC), a privately-held corporation based in Tokyo, Japan, and in October 2017, we acquired Robopolis SAS (Robopolis), a privately-held corporation distributing iRobot products in seven European countries.
Acquisitions and combinations are accompanied by a number of risks, including the difficulty of integrating the operations and personnel of the acquired companies, the potential disruption of our ongoing business, the potential distraction of management, potential difficulty in managing and maintaining key customer relationships, expenses related to the acquisition and potential unknown liabilities associated with acquired businesses. Any inability to integrate completed acquisitions or combinations in an efficient and timely manner could have an adverse impact on our results of operations. In addition, we may not be able to recognize any expected synergies or benefits in connection with our recently completed acquisitions of SODC or Robopolis or any future acquisitions or combinations. If we are not successful in completing acquisitions or combinations that we may pursue in the future, we may incur substantial expenses and devote significant management time and resources without a successful result. In addition, future acquisitions could require use of substantial portions of our available cash or result in dilutive issuances of securities.

Our service providers may experience business interruptions, delays, or quality control issues, which may negatively impactharm our business and operating results.
As we expand our operations, we expect to use additional enterprise resource planning systems and account and technology service providers that may also be essential to managing our business. Our ability to manage our business would suffer if one or more of our providers suffer an interruption in their business, or experience delays, disruptions or quality control problems in their operations, or we have to change or add systems and services. While we conduct reasonable diligence on our service providers, we may not always be able to control the quality of the systems and services we receive from these providers, which could impair our ability to maintain appropriate internal controls over financial reporting and complete timely and accurate financial reporting, and may impact our business, operating results and financial condition.

Our valuation estimates for our recently completed and future acquisitions are based upon assumptions that may differ from actual results.
Charges to earnings as a result of acquisitions may adversely affect our operating results in the foreseeable future, which could have a material and adverse effect on the market value of our common stock.  In particular, we have allocated the cost of acquiring businesses to the individual assets acquired and liabilities assumed, including various identifiable intangible assets such as acquired technology, acquired trade names and acquired customer relationships based on their respective fair values. Our estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain. After we complete an acquisition, the following factors could result in material charges and adversely affect our operating results and may adversely affect our cash flows:
costs incurred to combine the operations of businesses we acquire, such as transitional employee expenses and employee retention, redeployment or relocation expenses;
impairment of goodwill or intangible assets;
amortization of intangible assets acquired;
a reduction in the useful lives of intangible assets acquired;
identification of or changes to assumed contingent liabilities, both income tax provision and non-incomeother tax related after our final determination of the amounts for these contingencies or the conclusion of the measurement period (generally up to one year from the acquisition date), whichever comes first;
chargesliabilities may be insufficient if taxing authorities are successful in asserting tax positions that are contrary to our operating resultsposition. Additionally, there is no guarantee that we will realize our deferred tax assets.
From time to eliminate certain duplicative pre-merger activities, to restructure our operations or to reduce our cost structure; and
charges to our operating results resulting from expenses incurred to effect the acquisition.
Iftime, we are unableaudited by various federal, state, local and foreign authorities regarding income tax matters. Significant judgment is required to attractdetermine our provision for income taxes and retain additional skilled personnel,our liabilities for federal, state, local and foreign taxes. Although we may be unablebelieve our approach to growdetermine the appropriate tax treatment is supportable and in accordance with relevant authoritative guidance, it is possible that a tax authority will take a final tax position that is materially different than that which is reflected in our business.
To execute our growth plan, we must attract and retain additional, highly-qualified personnel. Competition for hiring these employees is intense, especially with regard to engineers with high levels of experience in designing, developing and integrating robots and engineers with expertise in artificial intelligence, machine learning and cloud applications. Many of the companies with which we compete for hiring experienced employees have greater resources than we have. If we fail to attract new technical personnel or fail to retain and motivate our current employees, our business and future growth prospects could be severely harmed.
We depend on the experience and expertise of our senior management team and key technical employees, and the loss of any key employee may impair our ability to operate effectively.
Our success depends upon the continued services of our senior management team and key technical employees, such as our project management personnel and senior engineers. Each of our executive officers, key technical personnel and other employees could terminate his or her relationship with us at any time. The loss of any member of our senior management team might significantly delay or prevent the achievement of our business objectives and could materially harm our business and customer relationships. In addition, because of the highly technical nature of our robots, the loss of any significant number of our existing engineering and project management personnelincome tax provision. Such differences could have a material adverse effect on our income tax provision or benefit, in the reporting period in which such determination is made and, consequently, on our results of operations, financial position and/or cash flows for such period.
The realization of our deferred tax assets ultimately depends on the existence of sufficient income in either the carryback or carryforward periods under the tax law. Due to significant estimates utilized in establishing a valuation allowance and the potential for changes in facts and circumstances, it is possible that we will be required to record a valuation allowance in future reporting periods. Our results of operations would be impacted negatively if we determine that a deferred tax asset valuation allowance is required in a future reporting period.
We may incur costs in complying with changing tax laws in the United States and abroad, which could adversely impact our cash flow, financial condition and results of operations.
We are a U.S.-based company subject to taxes in multiple U.S. and foreign tax jurisdictions. Our profits, cash flow and effective tax rate could be adversely affected by changes in the tax rules and regulations in the jurisdictions in which we do business, unanticipated changes in statutory tax rates and changes to our global mix of earnings.
Environmental laws and regulations and unforeseen costs could negatively impact our future earnings.
The manufacture and sale of our products in certain states and countries may subject us to environmental and other regulations. We also face increasing complexity in our product design as we adjust to legal and regulatory requirements relating to our products. There is no assurance that such existing laws or future laws will not impair future earnings or results of operations.
Business disruptions resulting from international uncertainties could negatively impact our profitability.
We derive, and expect to continue to derive, a significant portion of our revenue from international sales in various European and Asian markets, and Canada. For the fiscal years ended January 1, 2022, January 2, 2021 and December 28, 2019, sales to non-U.S. customers accounted for 51.8%, 47.9% and 50.3% of total revenue, respectively. We expect that international revenues will continue to account for a significant percentage of our revenues for the foreseeable future. Our international revenue and operations are subject to a number of material risks, including, but not limited to:
difficulties in staffing, managing and supporting operations in multiple countries;
19

Table of Contents
difficulties in enforcing agreements and collecting receivables through foreign legal systems and other relevant legal issues;
fewer legal protections for intellectual property;
foreign and U.S. taxation issues, tariffs, and international trade barriers;
difficulties in obtaining any necessary governmental authorizations for the export of our products to certain foreign jurisdictions;
potential fluctuations in foreign economies;
government currency control and restrictions on repatriation of earnings;
fluctuations in the value of foreign currencies and interest rates;
general economic and political conditions in the markets in which we operate;
domestic and international economic or political changes, hostilities and other disruptions in regions where we currently operate or may operate in the future;
changes in foreign currency exchange rates;
different and changing legal and regulatory requirements in the jurisdictions in which we currently operate or may operate in the future; and
our relationships with international distributors, some of whom may be operating without written contracts.
Negative developments in any of these areas in one or more countries could result in a reduction in demand for our products, the cancellation or delay of orders already placed, threats to our intellectual property, difficulty in collecting receivables, and a higher cost of doing business, any of which could negatively impact our business, financial condition or results of operations. Moreover, our sales to customers outside the United States are primarily denominated in Euro and Japanese Yen and fluctuations in the value of foreign currencies relative to the U.S. dollar may make our products more expensive than other products, which could harm our business.
The United Kingdom’s exit from the EU, commonly referred to as "Brexit," has caused significant political and economic uncertainty in the United Kingdom, EU, and elsewhere. The impact of Brexit and the resulting turmoil on the political and economic future of the United Kingdom and the EU is uncertain, and we may be adversely affected in ways we cannot currently anticipate. The United Kingdom and the EU have signed a EU-UK Trade and Cooperation Agreement (the "TCA"), which became provisionally applicable on January 1, 2021 and will become formally applicable once ratified by both the United Kingdom and the EU. The ultimate effects of Brexit will depend, in part, on how the terms of the TCA take effect in practice and on any other agreements the United Kingdom may make with the EU. Brexit also may result in significant changes in the British regulatory environment, now that legislation can diverge from EU legislation in many areas, which could increase our compliance costs. We may find it more difficult to conduct business in the United Kingdom and the EU, as Brexit will result in increased regulatory complexity and increased restrictions on the movement of capital, goods and personnel. Any of these effects of Brexit, and other similar referenda that we cannot anticipate, could disrupt our operations and adversely affect our operating results.
If we experience a disaster or other business continuity problem, we may not be able to recover successfully, which could cause material financial loss, loss of human capital, regulatory actions, reputational harm, or legal liability.
If we experience a local or regional disaster or other business continuity problem, such as an earthquake, terrorist attack, pandemic or other natural or man-made disaster, our continued success will depend, in part, on the availability of our personnel, our office facilities, and the proper functioning of our computer, telecommunication and other related systems and operations. As we grow our operations in new geographic regions, the potential for particular types of natural or man-made disasters, political, economic or infrastructure instabilities, or other country- or region-specific business continuity risks increases. For example, the COVID-19 pandemic has disrupted and will continue to disrupt our supply chain and manufacturers, resulting in a disruption in manufacturing our products as further discussed in the risk factors entitled "We depend on a limited number of manufacturers, and our reputation and results of operations would be harmed if these manufacturers fail to meet our requirements" below and "Our business has been, and will continue to be, adversely affected by the ongoing coronavirus pandemic" above.

The effects of regulations relating to conflict minerals may adversely affect our business.
On August 22, 2012, under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the SEC adopted new requirements for companies that use certain minerals and metals, known as conflict minerals, in their products, whether or not these products are manufactured by third parties. These requirements require companies to research, disclose and report whether or not such minerals originate from the Democratic Republic of Congo and adjoining countries. The implementation of these requirements could adversely affect the sourcing, availability and pricing of such minerals if they are found to be used in the manufacture of our products. In addition, we continue to incur additional costs to comply with the disclosure requirements, including costs related to determining the source of any of the relevant minerals and metals used in our products. Since our supply chain is complex, we may not be able to sufficiently verify the origins for these minerals and metals used in our products through the due diligence procedures that we implement, which may harm our reputation. In such event, we may also face difficulties in satisfying customers who require that all of the components of our products are certified as conflict mineral free.
Risks related to our Intellectual Property and Technology
If we fail to protect, or incur significant costs in defending, our intellectual property and other proprietary rights, our business and results of operations could be materially harmed.
Our success depends on our ability to protect our intellectual property and other proprietary rights. We rely primarily on patents, trademarks, copyrights, trade secrets and unfair competition laws, as well as license agreements and other contractual provisions, to protect our intellectual property and other proprietary rights. Significant technology used in our products,

however, is not the subject of any patent protection, and we may be unable to obtain patent protection on such technology in the future. Moreover, existing U.S. legal standards relating to the validity, enforceability and scope of protection of intellectual property rights offer only limited protection, may not provide us with any competitive advantages, and may be challenged by third parties. In addition, the laws of countries other than the United States in which we market our products may afford little or no effective protection of our intellectual property. Patents which may be granted to us in certain foreign countries may be subject to opposition proceedings brought by third parties or result in suits by us, which may be costly and result in adverse consequences for us. Accordingly, despite our efforts, we may be unable to prevent third parties from infringing upon or misappropriating our intellectual property or otherwise gaining access to our technology. Unauthorized third parties may try to copy or reverse engineer our products or portions of our products or otherwise obtain and use our intellectual property. If we fail to protect our intellectual property and other proprietary rights, our business, results of operations or financial condition could be materially harmed.
In addition, defending our intellectual property rights may entail significant expense. We believe that certain products in the marketplace may infringe our existing intellectual property rights. We have, from time to time, resorted to legal proceedings to protect our intellectual property and may continue to do so in the future. For example, in 2017on October 15, 2019, we initiated a multi-partypatent infringement lawsuit in federal district court in Massachusetts against SharkNinja Operating LLC and its related entities ("SharkNinja") for infringement of five patents for technology related to robotic vacuum cleaners. In addition, we sought a preliminary injunction against SharkNinja for infringement of three U.S. patents. SharkNinja has in parallel sought declarations of non-infringement of thirteen U.S. patents owned by iRobot. On November 26, 2019, the federal district court in Massachusetts denied iRobot's motion for a preliminary injunction. On January 28, 2021, we initiated litigation against SharkNinja at the U.S. International Trade Commission ("ITC") as well as in federal district court in Massachusetts based on claims of patent infringement. infringement of five additional U.S. patents, and on January 5-12, 2022 the ITC held a trial on four of those patents and a final determination has not been made.
There is no guarantee that we will prevail on these or other patent infringement claims against third parties. We may be required to expend significant resources to monitor and protect our intellectual property rights. In addition, any of our intellectual property rights may be challenged by others or invalidated through administrative processes or litigation. If we resort to legal proceedings to enforce our intellectual property rights or to determine the validity and scope of the intellectual property or other proprietary rights of others, the proceedings could result in significant expense to us and divert the attention and efforts of our management and technical employees, even if we were to prevail.
In addition, in the United States certain of our patents have been, and may continue to be, challenged by inter parte review or opposition proceedings. If our patents are subjected to inter parte review or opposition proceedings, we may incur significant costs to defend them. Further, our failure to prevail in any such proceedings could limit the patent protection available for our innovations.
We may be sued by third parties for alleged infringement of their proprietary rights, which could be costly, time-consuming and limit our ability to use certain technologies in the future.
We are currently defendingIn the past we have faced multiple lawsuits based on claims of patent infringement. If the size of our markets increases, we would be more likely to be subject to claims that our technologies infringe upon the intellectual property or other proprietary rights of third parties. In addition, the vendors from which we license technology used in our products could become subject to
21

Table of Contents
similar infringement claims. Our vendors, or we, may not be able to withstand third-party infringement claims. Any claims, with or without merit, could be time-consuming and expensive, and could divert our management’s attention away from the execution of our business plan. Moreover, any settlement or adverse judgment resulting from the claim could require us to pay substantial amounts or obtain a license to continue to use the technology that is the subject of the claim, or otherwise restrict or prohibit our use of the technology. There can be no assurance that we would be able to obtain a license from the third party asserting the claim on commercially reasonable terms, if at all, that we would be able to develop alternative technology on a timely basis, if at all, or that we would be able to obtain a license to use a suitable alternative technology to permit us to continue offering, and our customers to continue using, our affected product. In addition, we may be required to indemnify our retail and distribution partners for third-party intellectual property infringement claims, which would increase the cost to us of an adverse ruling in such a claim. An adverse determination could also prevent us from offering our products to others. Infringement claims asserted against us or our vendors may have a material adverse effect on our business, results of operations or financial condition.
Global economicIn addition, we incorporate open source software into our products, and we may continue to incorporate open source software into our products in the future. Open source software is generally licensed by its authors or other third parties under open source licenses. Some of these licenses contain requirements that we make available source code for modifications or derivative works we create based upon the open source software, and that we license such modifications or derivative works under the terms of a particular open source license or other license granting third parties certain rights of further use. If an author or other third party that distributes open source software that we use or license were to allege that we had not complied with the conditions of the applicable license, we could be required to incur significant legal expenses defending against those allegations and any associated impact on consumer spending could have a material adverse effect onbe subject to significant damages, enjoined from offering or selling our products that contained the open source software and required to comply with the foregoing conditions. Any of the foregoing could disrupt and harm our business results of operations and financial condition.
Continued economic uncertaintyCybersecurity risks could adversely affect our business and reductionsdisrupt our operations.
The threats to network and data security are increasingly diverse and sophisticated. Despite our efforts and processes to prevent breaches, our devices, as well as our servers, computer systems, and those of third parties that we use in consumer spending, particularly in certain international marketsour operations are vulnerable to cybersecurity risks, including cyber attacks such as viruses and worms, phishing attacks, distributed denial-of-service attacks, ransomware, and similar disruptions from unauthorized tampering with our servers and computer systems or those of third parties that we use in our operations, which could lead to interruptions, delays, loss of critical data, and loss of consumer confidence. In addition, we may be the European Union, Chinatarget of email scams that attempt to acquire sensitive information or company assets. Despite our efforts to create security barriers to such threats, we may not be able to entirely mitigate these risks. These threats may be increased due to the work-from-home policies implemented by us and Japan,our customers, suppliers and distributors as a result of mitigation measures related to the COVID-19 pandemic. Any cyber attack that attempts to obtain our data and assets, disrupt our service, or otherwise access our systems, or those of third parties we use, if successful, could adversely affect our business, operating results, and financial condition, be expensive to remedy, and damage our reputation. Our cyber insurance may result in reductionsnot protect against all of the costs and liabilities arising from a cyber attack.
If we suffer data breaches involving the designs, schematics or source code for our products, our brand, business and financial results could be adversely affected.
We attempt to securely store our designs, schematics and source code for our products as they are created. A breach, whether physical, electronic or otherwise, of the systems on which this sensitive data is stored could lead to damage or piracy of our products. If we or our partners are subject to data security breaches, we may have a loss in sales or increased costs arising from the restoration or implementation of our consumer robots. Additionally, disruptions in credit markets may materially limit consumer credit availability and restrict credit availabilityadditional security measures, either of our retail customers, which would also impact purchases of our consumer robots. Any reduction in sales of our consumer robots, resulting from reductions in consumer spending or continued disruption in the availability of credit to retailers or consumers, could materially and adversely affect our brand, business and financial results.
We operate our business in jurisdictions where intellectual property theft or compromise is common.
Currently, we maintain significant operations in China, where a majority of our products are manufactured. Subject to contractual confidentiality obligations, we are required to share significant product design materials with third-parties necessary for the design and manufacture of our products. We cannot be sure that our data or intellectual property will not be compromised through cyber-intrusion, theft or other means, particularly when the data or intellectual property is held by partners in foreign jurisdictions. Should our intellectual property be compromised, it may be difficult to enforce our rights in China and other foreign jurisdictions in which we operate.

We collect, store, process, and use customer data, including certain personal and robot-specific information, which subjects us to governmental regulation and other legal obligations related to privacy, information security, and data protection, and any security breaches or our actual or perceived failure to comply with such legal obligations could harm our business.
Our latest floor cleaning robots, as well as additional products in development, collect, store, process, and use certain customer data, which subjects us to governmental regulation and other legal obligations related to privacy, information security, and data protection, and any security breaches or our actual or perceived failure to comply with such legal obligations could harm our business. We collect, store, process, and use personal information and other user data, and we rely on third parties that are not directly under our control to do so as well. If our security measures, some of which are managed by third parties, are breached or fail, unauthorized persons may be able to obtain access to or acquire sensitive user data, which may expose us to a risk of loss, litigation, or regulatory proceedings. Depending on the nature of the information compromised, in the event of a data breach or other unauthorized access to or acquisition of our user data, we may also have obligations to notify users about the incident, and we may need to provide some form of remedy, such as a subscription to a credit monitoring service, for the individuals affected by the incident. In addition, the regulatory environment surrounding information security and privacy is increasingly demanding, with frequent imposition of new and changing requirements. For example, the European Union's ("EU") General Data Protection Regulation ("GDPR") and the California Consumer Privacy Act impose significant requirements on how we collect, process and transfer personal data, as well as significant fines for non-compliance. Compliance with changes in privacy and information security laws and standards may result in significant expense due to increased investment in technology and the development of new operational processes. Moreover, a growing number of legislative and regulatory bodies have adopted consumer notification requirements in the event of unauthorized access to or acquisition of certain types of personal data. Such breach notification laws continue to evolve and may be inconsistent from one jurisdiction to another. Complying with these obligations could cause us to incur substantial costs and could increase negative publicity surrounding any incident that compromises user data.
Further, we may be or become subject to data localization laws mandating that data collected in a foreign country be processed and stored only within that country. Russia adopted such a law in 2014, and a similar law became effective in China in November 2021. If other countries in which we have customers were to adopt a data localization law, we could be required to expand our data storage facilities there or build new ones in order to comply. The expenditure this would require, as well as costs of compliance generally, could harm our financial condition.
Our products are complex and could have unknown defects or errors, which may give rise to claims against us, diminish our brand or divert our resources from other purposes.
Our robots rely on the interplay among behavior-based artificially intelligent systems, real-world dynamic sensors, user-friendly interfaces and tightly-integrated, electromechanical designs to accomplish their missions. Despite testing, our new or existing products have contained defects and errors and may in the future contain defects, errors or performance problems when first introduced, when new versions or enhancements are released, or even after these products have been used by our customers for a period of time. These problems have and may continue to result in expensive and time-consuming design modifications or warranty charges, delays in the introduction of new products or enhancements, significant increases in our service and maintenance costs, exposure to liability for damages, mandatory or voluntary recall or product upgrades, damaged customer relationships and harm to our reputation, any of which could materially harm our results of operations and financial condition.
Because weability to achieve market acceptance. Our quality control procedures relating to the raw materials and components that it receives from third-party suppliers as well as our quality control procedures relating to its products after those products are an increasingly global business thatdesigned, manufactured and packaged may not be sufficient. In addition, increased development and warranty costs, including the costs of any mandatory or voluntary recall, could be substantial and could reduce our operating margins. The existence of any defects, errors, or failures in the years ended December 30, 2017, December 31, 2016 and January 2, 2016 generated approximately 48.8%, 51.2% and 56.0%, respectively, of our total revenue from sales to customers outside of the United States, we are subject to a number of additional risks including foreign currency fluctuations. These risks are magnified with our expanding global presence as a result of our recent acquisitions of SODC and Robopolis. These foreign currency fluctuations may make our products more expensivecould also lead to product liability claims or lawsuits against us. A successful product liability claim could result in substantial cost, diminish our distributors,brand and divert management’s attention and resources, which in turn maycould have a negative impact sales directly or the ability or willingness of our distribution partners to invest in growing product demand.
Our primary exposure to movements in foreign currency exchange rates relates to non-U.S. dollar denominated sales and operating expenses worldwide. Weakening of foreign currencies relative to the U.S. dollar could adversely affect the U.S. dollar value of our foreign currency-denominated sales and earnings, and lead us to raise international pricing, which may reduce

demand for our products. In some circumstances, for competitive or other reasons, we may decide not to raise local prices to fully offset the strengthening of the U.S. dollar, or for any other reason, which would adversely affect the U.S. dollar value of our foreign currency denominated sales and earnings. Conversely, a strengthening of foreign currencies relative to the U.S. dollar, while generally beneficial to our foreign currency-denominated sales and earnings, could cause us to reduce international pricing, incur losses on our foreign currency derivative instruments, and incur increased operating expenses, thereby limiting any benefit. Additionally, strengthening of foreign currencies may also increase our cost of product components denominated in those currencies, thus adversely affecting gross margins.
We use derivative instruments, such as foreign currency forward contracts, to hedge certain exposures to fluctuations in foreign currency exchange rates. The use of such hedging activities may not offset any, or more than a portion, of the adverse financial effects of unfavorable movements in foreign exchange rates over the limited time the hedges are in place. In addition, our counterparties may be unable to meet the terms of the agreements. We seek to mitigate this risk by limiting counterparties to major financial institutions and by spreading the risk across several major financial institutions.
We are subject to a variety of U.S. and foreign laws and regulations that are central to our business; our failure to comply with these laws and regulations could harm our business or our operating results.
We are or may become subject to a variety of laws and regulations in the United States and abroad that involve matters central to our business, including laws and regulations regarding consumer protection, advertising, electronic commerce, intellectual property, manufacturing, anti-bribery and anti-corruption, and economic or other trade prohibitions or sanctions.
The increasingly global nature of our business operations subjects us to domestic and foreign laws and regulations such as the U.S. Foreign Corrupt Practices Act, or FCPA, the U.K. Bribery Act, and similar anti-bribery and anti-corruption laws in other jurisdictions. Our products are also subject to U.S. export controls, including the U.S. Department of Commerce’s Export Administration Regulations and various economic and trade sanctions regulations established by the Treasury Department’s Office of Foreign Assets Controls. Given the increasing number of foreign laws to which we are subject and the high level of complexity of these laws, there is a risk that some provisions may be inadvertently breached by us or by our subsidiaries, for example through fraudulent or negligent behavior of individual employees, our failure to comply with certain formal documentation requirements, or otherwise. If we incur liability for noncompliance under these laws or regulations, we may be forced to implement new measures to reduce our exposure to this liability. This may require us to expend substantial resources or to discontinue certain products or services, which would negatively affect our business, financial condition and operating results. In addition, any negative publicity directedresults of operations.
Risks Related to usOwnership of our Common Stock
The market price of our common stock may fluctuate significantly.

The stock market, as a resultwhole, also has experienced extreme price and volume fluctuations that have affected the market price of compliance effortsthe common stock of many technology companies in ways that may have been unrelated to such companies’ operating performance. In addition, the market price of our common stock may be, and we believe recently has been, significantly impacted by investors covering large short positions in our common stock. Furthermore, we believe the market

price of our common stock should reflect future growth and profitability expectations. If we fail to meet these expectations, the market price of our common stock may significantly decline.
In addition, there are many other factors that may cause the market price of our common stock to fluctuate, including:
actual or anticipated variations in our quarterly operating results, including fluctuations resulting from changes in foreign exchange rates or acquisitions by us, or the quarterly financial results of companies perceived to be similar to us;
deterioration and decline in general economic, industry and/or market conditions;
announcements of technological innovations or new products or services by us or our competitors;
changes in estimates of our financial results or recommendations by market analysts;
announcements by us or our competitors of significant projects, contracts, acquisitions, strategic alliances or joint ventures; and
changes in our capital structure, such as future issuances of securities or the incurrence of additional debt.
Our financial results often vary significantly from quarter-to-quarter due to a number of factors, which may lead to volatility in our stock price.
Our quarterly revenue and other liabilities under these laws or regulations could harmoperating results have varied in the past and are likely to continue to vary significantly from quarter-to-quarter in the future. These fluctuations may be due to numerous factors including:
the size, timing and mix of orders from retail stores and distributors for our business and operating results.consumer robots;
Environmental laws and regulations and unforeseen costs could negatively impact our future earnings.the mix of products that we sell in the period;
The manufacture and saledisruption of supply of our products from our manufacturers;
disruptions to our supply chain due to inclement weather, pandemics, labor disruptions or other factors beyond our control, including COVID-19;
seasonality in the sales of our products;
the timing of new product introductions;
unanticipated costs incurred in the introduction of new products;
costs and availability of labor and raw materials;
costs of freight and tariffs;
changes in our rate of returns for our consumer products;
our ability to introduce new products and enhancements to our existing products on a timely basis; and
warranty costs associated with our consumer products.
We cannot be certain states and countries may subjectthat our revenues will grow at rates that will allow us to environmentalmaintain profitability during every fiscal quarter, or even every fiscal year. We base our current and other regulations. We also face increasing complexity infuture expense levels on our product design as we adjust to legalinternal operating plans and regulatory requirements relating tosales forecasts, including forecasts of holiday sales for our consumer products. There is no assurance that such existing laws or future laws will not impair future earnings or results of operations.
Business disruptions resulting from international uncertainties could negatively impact our profitability.
We derive, and expect to continue to derive, aA significant portion of our revenue from internationaloperating expenses, such as research and development expenses, certain marketing and promotional expenses and employee wages and salaries, do not vary directly with sales and are difficult to adjust in various European and Far East markets, and Canada, particularly following our acquisitions of SODC and Robopolis. For the fiscal years ended December 30, 2017, December 31, 2016 and, January 2, 2016,short term. As a result, if sales to non-U.S. customers accounted for 48.8%, 51.2% and 56.0% of total revenue, respectively. We expect that international revenues will continue to account for a significant percentage ofquarter are below our revenues for the foreseeable future. Our international revenue and operations are subject to a number of material risks, including, but not limited to:
difficulties in staffing, managing and supporting operations in multiple countries;
difficulties in enforcing agreements and collecting receivables through foreign legal systems and other relevant legal issues;
fewer legal protections for intellectual property;
foreign and U.S. taxation issues, tariffs, and international trade barriers;
difficulties in obtaining any necessary governmental authorizations for the export of our products to certain foreign jurisdictions;
potential fluctuations in foreign economies;
government currency control and restrictions on repatriation of earnings;

fluctuations in the value of foreign currencies and interest rates;
general economic and political conditions in the markets in whichexpectations, we operate;
domestic and international economic or political changes, hostilities and other disruptions in regions where we currently operate or may operate in the future;
changes in foreign currency exchange rates;
different and changing legal and regulatory requirements in the jurisdictions in which we currently operate or may operate in the future; and
our relationships with international distributors, some of whom may be operating without written contracts.
Negative developments in any of these areas in one or more countries could result in a reduction in demand for our products, the cancellation or delay of orders already placed, threats to our intellectual property, difficulty in collecting receivables, and a higher cost of doing business, any of which could negatively impact our business, financial condition or results of operations. Moreover, our sales, including direct sales to customers outside the United States, are primarily denominated in U.S. dollars, and downward fluctuations in the value of foreign currencies relative to the U.S. dollar may make our products more expensive than other products, which could harm our business.
Moreover, the United Kingdom (UK) held a referendum on June 23, 2016 in which a majority of voters voted to exit the European Union (EU). Due to the unprecedented nature of the proposed withdrawal, significant uncertainty exists surrounding the timing and terms of the proposed exit. We have operations in the UK and business activities in several EU member states whose currencies, namely British Pound Sterling and Euro, economies, taxation, and trade regulation, among other factors, could be adversely impacted by the negotiations and outcomes of the UK’s leaving the EU, which is likely to be a lengthy and complicated process.  While we do not anticipate near term adverse effects on business operations, these events could have a material adverse effect on our business operations, results of operations and financial condition over time.
If we experience a disaster or other business continuity problem, we maymight not be able to recover successfully, which could cause material financial loss, loss of human capital, regulatory actions, reputational harm, or legal liability.
If we experiencereduce operating expenses for that quarter. Accordingly, a local or regional disaster or other business continuity problem, such as an earthquake, terrorist attack, pandemic or other natural or man-made disaster, our continued success will depend, in part, on the availability of our personnel, our office facilities, and the proper functioning of our computer, telecommunication and other related systems and operations. As we grow our operations in new geographic regions, the potential for particular types of natural or man-made disasters, political, economic or infrastructure instabilities, or other country- or region-specific business continuity risks increases.
The effects of regulations relating to conflict minerals may adversely affect our business.
On August 22, 2012, under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the SEC adopted new requirements for companies that use certain minerals and metals, known as conflict minerals, in their products, whether or not these products are manufactured by third parties. These requirements require companies to research, disclose and report whether or not such minerals originate from the Democratic Republic of Congo and adjoining countries. The implementation of these requirements could adversely affect the sourcing, availability and pricing of such minerals if they are found to be used in the manufacture of our products. In addition, we continue to incur additional costs to comply with the disclosure requirements, including costs related to determining the source of any of the relevant minerals and metals used in our products. Since our supply chain is complex, we may not be able to sufficiently verify the origins for these minerals and metals used in our products through the due diligence procedures that we implement, which may harm our reputation. In such event, we may also face difficulties in satisfying customers who require that all of the components of our products are certified as conflict mineral free. 
Our income tax provision and other tax liabilities may be insufficient if taxing authorities are successful in asserting tax positions that are contrary to our position. Additionally, there is no guarantee that we will realize our deferred tax assets.
From time to time, we are audited by various federal, state, local and foreign authorities regarding income tax matters. Significant judgment is required to determine our provision for income taxes and our liabilities for federal, state, local and foreign taxes. Although we believe our approach to determining the appropriate tax treatment is supportablesales shortfall during a fiscal quarter, and in accordance with relevant authoritative guidance it is possible thatparticular the fourth quarter of a tax authority will take a final tax position that is materially different than that which is reflected in our income tax provision. Such differencesfiscal year, could have a material adversedisproportionate effect on our income tax provisionoperating results for that quarter or benefit, in the reporting period in which such determination is made and, consequently, on our resultsthat year. Because of operations, financial position and/or cash flows for such period.
The realizationquarterly fluctuations, we believe that quarter-to-quarter comparisons of our deferred tax assets ultimately depends on the existence of sufficient income in either the carryback or carryforward periods under the tax law. Due to significant estimates utilized in establishing a valuation allowance and the potential for changes in facts and circumstances, it is possible that we will be required to record a valuation allowance in future

reporting periods. Ouroperating results of operations would be impacted negatively if we determine that a deferred tax asset valuation allowance is required in a future reporting period.
The effect of comprehensive U.S. tax reform legislation on us, whether adverse or favorable, is uncertain.
On December 22, 2017, President Trump signed into law H.R. 1, "An Act to provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year 2018" (informally titled the "Tax Cuts and Jobs Act"). Among a number of significant changes to the U.S. federal income tax rules, the Tax Cuts and Jobs Act (the "Act") reduces the marginal U.S. corporate income tax rate from 35% to 21%, limits the deduction for net interest expense, limits the deduction for netare not necessarily meaningful. Moreover, our operating losses and eliminates net operating loss carrybacks, modifies or repeals many business deductions and credits, shifts the United States toward a more territorial tax system, and imposes new taxes to combat erosion of the U.S. federal income tax base. Our net deferred tax assets and liabilities will be revalued at the newly enacted U.S. corporate rate, and the impact will be recognized in our tax expense in the year of enactment.  We continue to examine the impact this tax reform legislation may have on our business.  However, the effect of the Tax Cuts and Jobs Act on us and our affiliates, whether adverse or favorable, is uncertain, andresults may not become evident for some periodmeet expectations of equity research analysts or investors. If this occurs, the trading price of our common stock could fall substantially either suddenly or over time.

Provisions in our certificate of incorporation and by-laws or Delaware law might discourage, delay or prevent a change of control of our company or changes in our management and, therefore, depress the trading price of our common stock.
Provisions of our certificate of incorporation and by-laws and Delaware law may discourage, delay or prevent a merger, acquisition or other change in control that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares of our common stock. These provisions may also prevent or frustrate attempts by our stockholders to replace or remove our management. These provisions include:
limitations on the removal of directors;
a classified board of directors so that not all members of our board are elected at one time;
advance notice requirements for stockholder proposals and nominations;
the inability of stockholders to act by written consent or to call special meetings;
the ability of our board of directors to make, alter or repeal our by-laws; and
the ability of our board of directors to designate the terms of and issue new series of preferred stock without stockholder approval.
The affirmative vote of the holders of at least 75% of our shares of capital stock entitled to vote is necessary to amend or repeal the above provisions of our certificate of incorporation. In addition, absent approval of our board of directors, our by-laws may only be amended or repealed by the affirmative vote of the holders of at least 75% of our shares of capital stock entitled to vote.
In addition, Section 203 of the Delaware General Corporation Law prohibits a publicly-held Delaware corporation from engaging in a business combination with an interested stockholder, generally a person which together with its affiliates owns, or within the last three years has owned, 15% of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner.
The existence of the foregoing provisions and anti-takeover measures could limit the price that investors might be willing to pay in the future for shares of our common stock. They could also deter potential acquirers of our company, thereby reducing the likelihood that you could receive a premium for your common stock in an acquisition.
If significant tariffs or other restrictions are placed on Chinese imports or any related counter-measures are taken by China, our revenues and results of operations may be materially harmed.
The current U.S. administration has signaled it may alter trade agreements and terms between China and the United States, including limiting trade with China and/or imposing a tariff on imports from China. If any such restrictions or tariffs are imposed on products that we import to our customers, we would be required to raise our prices which may result in the loss of customers and harm our business.
Our products are complex and could have unknown defects or errors, which may give rise to claims against us, diminish our brand or divert our resources from other purposes.
Our robots rely on the interplay among behavior-based artificially intelligent systems, real-world dynamic sensors, user-friendly interfaces and tightly-integrated, electromechanical designs to accomplish their missions. Despite testing, our new or existing products have contained defects and errors and may in the future contain defects, errors or performance problems when first introduced, when new versions or enhancements are released, or even after these products have been used by our customers

for a period of time. These problems could result in expensive and time-consuming design modifications or warranty charges, delays in the introduction of new products or enhancements, significant increases in our service and maintenance costs, exposure to liability for damages, mandatory or voluntary recall or product upgrades, damaged customer relationships and harm to our reputation, any of which could materially harm our results of operations and ability to achieve market acceptance. Our quality control procedures relating to the raw materials and components that it receives from third-party suppliers as well as our quality control procedures relating to its products after those products are designed, manufactured and packaged may not be sufficient. In addition, increased development and warranty costs, including the costs of any mandatory or voluntary recall, could be substantial and could reduce our operating margins. The existence of any defects, errors, or failures in our products could also lead to product liability claims or lawsuits against us. A successful product liability claim could result in substantial cost, diminish our brand and divert management’s attention and resources, which could have a negative impact on our business, financial condition and results of operations.
We spend significant amounts on advertising and other marketing campaigns, which may not be successful or cost effective.
We spend significant amounts on advertising and other marketing campaigns, such as television, print advertising, and social media, as well as increased promotional activities, to acquire new customers, and we expect our marketing expenses to increase in the future as we continue to spend significant amounts to increase awareness of our consumer robot products. For the years ended December 30, 2017, December 31, 2016 and January 2, 2016, sales and marketing expenses were $162.1 million, $115.1 million and $97.8 million, respectively, representing approximately 18.3%, 17.4%, and 15.9% of our revenue, respectively. While we seek to structure our advertising campaigns in the manner that we believe is most likely to encourage people to purchase our products, we may fail to identify advertising opportunities that satisfy our anticipated return on advertising spend as we scale our investments in marketing or to fully understand or estimate the conditions and behaviors that drive customer behavior. If any of our advertising campaigns prove less successful than anticipated in attracting customers, we may not be able to recover our advertising spend, and our revenue may fail to meet market expectations, either of which could have an adverse effect on our business. There can be no assurance that our advertising and other marketing efforts will result in increased sales of our products.General Risk Factors
We may not be able to obtain capital when desired on favorable terms, if at all, or without dilution to our stockholders.
We anticipate that our current cash, cash equivalents, cash provided by operating activities and funds available through our working capital line of credit facility, will be sufficient to meet our current and anticipated needs for general corporate purposes. We operate in an emerging technology market, however, which makes our prospects difficult to evaluate. It is possible that we may not generate sufficient cash flow from operations or otherwise have the capital resources to meet our future capital needs. In such cases we may need additional financing to execute on our current or future business strategies. If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders could be significantly diluted, and these newly-issued securities may have rights, preferences or privileges senior to those of existing stockholders. We cannot assure you that additional financing will be available on terms favorable to us, or at all. If adequate funds are not available or are not available on acceptable terms, if and when needed, our ability to fund our operations, take advantage of unanticipated opportunities, develop or enhance our products, or otherwise respond to competitive pressures would be significantly limited. In addition, our access to credit through our working capital line of credit facility may be limited by the restrictive financial covenants contained in thatthe agreement, which require us to maintain profitability.

Overview
iRobot is a leading global consumer robot company that designs and builds robots that empower people to do more both insidemore. With over 30 years of artificial intelligence ("AI") and outsideadvanced robotics experience, we are focused on building thoughtful robots and developing intelligent home innovations that help make life better for millions of people around the home. The Company's consumer robots help people find smarter ways to clean and accomplish more in their daily lives.world. iRobot's portfolio of solutionshome robots and smart home devices features proprietary technologies for the connected home and advanced concepts in cleaning, mapping and navigation, human-robot interaction and physical solutions. ForLeveraging this portfolio, we plan to add new capabilities and expand our offerings to help consumers make their homes easier to maintain, more than 25 years,efficient, more secure and healthier places to live.
Since our founding in 1990, we have been a pioneer indeveloped the robotics and consumer products industries. We sell our robots through a variety of distribution channels, including chain stores and other national retailers, through our on-line store, and through value-added distributors and resellers worldwide.
Over the past sixteen years, we have sold more than 20 million consumer robots worldwide. During 2016, we took several steps to become more focused on our well established consumer robots business and capitalize on the substantial opportunities available to us within consumer markets. We completed the sale of our defense and security business unit in April 2016.  In addition, we reallocated all of the research and development resources from our remote presence business to our consumer business during the first quarter of 2016, and exited the remote presence business during the second quarter of 2016. These actions were taken to solidify our position as the leader in diversified consumer robots and to focus on key technologies, with an emphasis on software, that allow our robots to understand the homes in which they operate. It is our intent to continue investing in these critical technologies and the economic opportunities they unlock.
During 2017, we continued to expand our global operations with the acquisition of two of our major distributors in Japan and Europe. On April 3, 2017, we closed the acquisition of the iRobot-related distribution business of Sales On Demand Corporation (SODC) based in Tokyo, Japan for approximately $16.6 million in cash. The acquisition of SODC will better enable us to maintain our leadership position and accelerate the growth of our business in Japan through direct control of pre- and post-sales market activities including sales, marketing, branding, channel relationships and customer service. It also expands our presence and customer outreach opportunities in Japan. Additionally, on October 2, 2017, we acquired our largest European distributor, Robopolis SAS, a French company (Robopolis) for approximately $170.1 million in cash, which was offset by acquired cash held by Robopolis and its subsidiaries, resulting in a net cash outlay of approximately $132.1 million. We anticipate that this acquisition will enhance our distribution network, ensure global brand consistency and better serve the needs of European consumers. We expect to drive continued growth in global markets through a consistent approach to all market activities including sales, marketing, branding, channel relationships and customer service. Both acquisitions provide us with more direct control over the go-to-market execution in these key regions.
As of December 30, 2017, we had 920 full-time employees. We have developed expertise in the disciplines necessary to design, build, sell and support durable, high-performance and cost-effective robots through the close integration of software, electronics and hardware. Our core technologies serve as reusable building blocks that we adapt and expand to develop next generation and new products,create next-generation robotic platforms. We believe that this approach accelerates the time to market, while also reducing the costs, time cost and risk ofother risks associated with product development. OurThese capabilities are amplified by our Genius platform, which leverages our considerable expertise and ongoing investment in AI, home understanding and machine vision technologies to provide consumers with greater control over our products, simple integration with other smart home devices, recommendations that further enhance the cleaning experience and the ability to share and transfer home knowledge across multiple iRobot robots. We believe that the capabilities within Genius will support our ability to build out a larger ecosystem that encompasses a broader range of adjacent robotic and smart home categories. We believe that our significant expertise in robot design, engineering, and engineeringsmart home technologies and targeted focus on understanding and addressing consumer needs, positions us well to expand our total addressable market and capitalize on the anticipated growth we expect in the market for robot-based consumer products.
Our continued success depends upon our ability to respond to a number of future challenges. We believe the most significant of these include increasing competition, and our ability to successfully develop and introduce products and product enhancements into both new and existing markets.
We also achieved a number of significant milestones over the past two years that we believe will assist us in continuing to generate profitable growth and enhance value for our shareholders. In particular, in 2016, we successfully launched Roomba 960, our second 900 series Roomba, that extends mapping, visual navigation and cloud connectivity to a wider range of customers. We also launched the Braava jet mopping robot, with precision jet sprayrobotic and vibrating cleaning head, focused on expanding our wet floor care business. Both the Roomba 900 series and Braava jet are significantly more complex products, delivering enhanced performance enabled by software. The iRobot HOME App, compatible with both the Roomba 900 series and Braava jet, helps users get the most out of their experience by allowing them to choose the appropriate cleaning options for their unique home. We also announced a relationship with Amazon Web Services, or AWS, that we believe will enable iRobot to address significant opportunities within our consumer business and the connected home. AWS Cloud is a managed cloud solution that enables connected devices to interact easily and securely with cloud applications and other devices. The AWS Cloud will enable iRobot to scale the number of connected robots it supports globally and allow for increased capabilities in the Smart Home. Additionally, we implemented new Roomba marketing programs in the United States that resulted in a significant return on our investment and which we plan to leverage as part of our strategy to accelerate growth in international markets. In 2017, we launched Roomba 690 and 890, extending Wi-Fi connectivity to the entire Roomba line. In addition, we launched several connected product features, including push notifications, Clean Map Reports and integrations with Amazon Alexa, Google Assistant and IFTTT platform technology.smart home categories.
Our total revenue for 20172021 was $883.9$1,565.0 million, which represents a 33.8%9.4% increase from 2016 revenue of $660.6 million.$1,430.4 million for 2020. Domestic consumer robots revenue grew $133.2$9.5 million, primarily due toor 1.3%, and international revenue increased sales as a result of significant investments in advertising media and national promotions as well asby $125.1 million, or 18.2%.
Since the strengthintroduction of the Roomba 900 series and Roomba 600 series.

Internationalrobotic vacuum cleaner ("RVC") in 2002, we have sold more than 35 million consumer robots worldwide to become a global, market-leading consumer robotics innovator with a strong presence in a number of major geographic regions worldwide. In 2021, iRobot generated annual revenue grewof $1,565.0 million while navigating very challenging market conditions as the COVID-19 pandemic continued to impact all aspects of our business. Most notably, we have faced supply chain challenges that have limited our ability to increase production to fulfill demand for our products, increased our costs to produce and ship our products and expanded the delivery timeframes required to fulfill orders.
Our commitment to innovation and funding critical research and development projects continued to yield tangible results through new product launches, and new and enhanced product features and functionality:

We launched two major upgrades of our Genius platform that delivered a wider range of features and functionality to provide users with greater control for where, when and how our Roomba and Braava robots clean. These enhancements also enabled tighter integration between our products and other smart home devices, and the ability for consumers to seamlessly transfer maps to new iRobot robots added into the home.
We launched the Roomba j7 Series, our first Roomba designed specifically to leverage our Genius platform and our first Roomba with the ability to identify objects. Powered by $94.6 millionGenius and featuring PrecisionVision Navigation technology, the Roomba j7 can detect, identify and avoid an expanding range of objects. We also launched the Roomba i1 Series, a lower-cost RVC that was initially sold at select retailers.
We introduced the iRobot H1 handheld vacuum, a premium portable vacuum for cleaning hard-to-reach areas.
In November 2021, we acquired Aeris, a fast-growing provider of premium air purifiers. The addition of Aeris helps expand iRobot’s total addressable market with a portfolio of air purifiers that we believe are differentiated by their sophisticated design, quality craftmanship, HEPA filtration, state-of-the-art engineering and software intelligence. Other 2021 highlights included our efforts to mitigate semiconductor chip shortages that constrained production of our floor cleaning robots and address a range of supply chain challenges that resulted in 2017 with increaseshigher-than-expected costs for components, raw materials and transportation. We also continued our process expanding production in most markets, offset byMalaysia. To support the growth of our direct-to-consumer sales channel, we continued to invest in improving the online buying experience on our digital properties and enhancing our marketing systems and tools to improve our efficiency and effectiveness in targeting our connected customers. We also continued to test, refine and expand robot-related subscription services for consumers in the United States, Japan and Europe.
COVID-19
In March 2020, the World Health Organization declared the outbreak of the novel coronavirus ("COVID-19") to be a declineglobal pandemic. Since then, COVID-19 has caused significant economic disruption directly and indirectly. In an effort to slow the spread of COVID-19 and improve the health and well-being of its citizens, governments around the world have implemented and continue to implement various measures, including travel restrictions, closure of non-essential businesses, border closures, vaccination-related mandates and social distancing. These actions have altered macroeconomic conditions, created recession-like environments and contributed to rising inflation, which has impacted retailers and consumers around the world. While consumer demand for our Roomba and Braava robots remained robust during 2021, COVID-19 has compounded a myriad of supply chain challenges, ranging from limited availability of certain semiconductor chips and rising component, raw materials and transportation costs. These challenges impacted revenue and profitability during 2021 and are expected to continue at least through the first half of 2022.
Among the many actions taken to support our employees during the pandemic, we have continued to adjust our global travel policies, maintain flexible work from home policies, and implement a wide range of sanitization and cleaning protocols to keep our offices safer. During 2022, we plan to continue to evolve our workplace policies in China.order to help safeguard the health and maximize the productivity of our workforce.
Fiscal Periods
We operate and report using a 52-53 week fiscal year ending on the Saturday closest to December 31. Accordingly, our fiscal quarters will end on the Saturday that falls closest to the last day of the third month of each quarter. As used in this Annual Report on Form 10-K, "fiscal 2021" refers to the 52-week fiscal year ending January 1, 2022, "fiscal 2020" refers to the 53-week fiscal year ended January 2, 2021, and "fiscal 2019" refers to the 52-week fiscal year ended December 28, 2019.

Key Financial Metrics and Non-GAAP Financial Measures
In addition to the measures presented in our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP"), we use the following key metrics, including non-GAAP financial measures, to evaluate and analyze our core operating performance and trends, and to develop short-term and long-term operational plans. The most directly comparable financial measures calculated under U.S. GAAP are Gross Profit and Operating (Loss) Income. In the fiscal years 2021, 2020 and 2019, we had Gross Profit of $550,299, $670,229 and $543,927, respectively, and Operating (Loss) Income of ($1,100), $146,322, and $86,618, respectively. A summary of key metrics and certain non-GAAP financial measures for the fiscal years 2021, 2020 and 2019, is as follows:

Our non-GAAP financial measures reflect adjustments based on the following items. These non-GAAP financial measures should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and the financial results calculated in accordance with GAAP and reconciliations from these results should be carefully evaluated.
Amortization of acquired intangible assets: Amortization of acquired intangible assets consists of amortization of intangible assets including completed technology, customer relationships, and reacquired distribution rights acquired in connection with business combinations.
Tariff Refunds: iRobot was granted a Section 301 List 3 Tariff Exclusion in April 2020, which temporarily eliminated tariffs on our products imported from China until December 31, 2020 and entitled us to a refund of all related tariffs previously paid since September 2018. We excluded the refunds for tariffs paid in fiscal 2018 and 2019 from our fiscal 2020 non-GAAP measures because those tariff refunds associated with tariff costs incurred in the past had no impact to our fiscal 2020 earnings.
Net Merger, Acquisition and Divestiture (Income) Expense: Net merger, acquisition and divestiture (income) expense primarily consists of transaction fees, professional fees, and transition and integration costs directly associated with mergers, acquisitions and divestitures. It also includes business combination adjustments after the measurement period has ended.
Stock-Based Compensation: Stock-based compensation is a non-cash charge relating to stock-based awards.
IP Litigation Expense, Net: IP litigation expense, net relates to legal costs incurred to litigate patent, trademark, copyright and false advertising infringements, or to oppose or defend against interparty actions related to intellectual property. Any settlement payment or proceeds resulting from these infringements are included or netted against the costs.
Gain/Loss on Strategic Investments: Gain/loss on strategic investments includes fair value adjustments, realized gains and losses on the sales of these investments and losses on the impairment of these investments.
Restructuring and Other: Restructuring charges are related to one-time actions associated with workforce reductions, including severance costs, certain professional fees and other costs directly associated with resource realignments tied to strategic initiatives or changes in business conditions.
Income tax adjustments: Income tax adjustments include the tax effect of the non-GAAP adjustments, calculated using the appropriate statutory tax rate for each adjustment. We reassess the need for any valuation allowance recorded based on the non-GAAP profitability and have eliminated the effect of the valuation allowance recorded in the U.S. jurisdiction. We also exclude certain tax items, including impact from stock-based compensation windfalls/shortfalls, that are not reflective of income tax expense incurred as a result of current period earnings.

We exclude these items from our non-GAAP measures to facilitate an evaluation of our current operating performance and comparisons to our past operating performance. These items may vary significantly in magnitude or timing and do not necessarily reflect anticipated future operating activities. In addition, we believe that providing these non-GAAP measures affords investors a view of our operating results that may be more easily compared with our peer companies.

Critical Accounting Policies and Estimates
Our consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements in conformity with generally accepted accounting principles in the United States requires managementus to make estimates and assumptions that affect the reported amounts of assets, and liabilities, revenue, and expenses and the disclosure of contingent assets and liabilities in the consolidated financial statements. Theserelated disclosures. Our estimates and judgments, include butassumptions are not limited to, revenue recognition (specifically sales returns and other allowances); valuation of goodwill and acquired intangible assets; accounting for business combinations; evaluating loss contingencies; and accounting for income taxes and related valuation allowances. We base these estimates and judgmentsbased on historical experience market participant fair value considerations, projected future cash flows and various other factors that we believe are reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. Actual results may differ from our estimates.

The accounting policies, whichmethods and estimates used to prepare our financial statements are described in the notesNote 2 Summary of Significant Accounting Policies of Notes to our consolidated financial statements,Consolidated Financial Statements in this Annual Report. We consider the following accounting policies involve a greater degreeto be those that are most important to the portrayal of judgment and complexity. Accordingly, we believe that the following accounting policies are the most critical to aid in fully understanding and evaluating our consolidated financial condition and resultsthat require a higher degree of operations.judgment:
revenue recognition and
accounting for income taxes.
Revenue Recognition
We primarily derive our revenue from product sales. Until the divestiture of the defense and security business unit in April 2016 (see Note 4), we also generated minimal revenue from government and commercial research and development contracts. We sell products directly to customers and indirectly through resellers and distributors. We recognize revenue from sales of robots under the terms of the customer agreementRevenue is recognized upon transfer of titlecontrol of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Revenue is allocated to distinct performance obligations and riskis recognized net of lossallowances for returns and other credits and incentives. Revenue is recognized only to the customer, netextent that it is probable that a significant reversal of estimated returnsrevenue will not occur and allowances, provided thatwhen collection is determined to be reasonably assuredconsidered probable.
Frequently, our contracts with customers contain multiple promised goods or services. Such contracts may include any of the following, the consumer robot, downloadable app, cloud services, potential future unspecified software upgrades, premium customer care and no significantextended warranties. For these contracts, we account for the promises separately as individual performance obligations remain.
Beginningif they are distinct. Performance obligations are considered distinct if they are both capable of being distinct and distinct within the context of the contract. In determining whether performance obligations meet the criteria for being distinct, we consider a number of factors, such as the degree of interrelation and interdependence between obligations, and whether or not the good or service significantly modifies or transforms another good or service in the third quarter of 2015, we introduced our first connected robot. Each sale ofcontract. Our consumer robots are highly dependent on, and interrelated with, the embedded software and cannot function without the software. As such, the consumer robots are accounted for as a connected robot represents a multiple-element arrangement containingsingle performance obligation. We have determined that the robot, an app, cloud services and potential future unspecified software upgrades. Revenue is allocatedupgrades represent one performance obligation to the deliverablescustomer to enhance the functionality and interaction with the robot (referred to collectively as "Cloud Services"). Other services and support are considered distinct and therefore are treated as separate performance obligations.
Significant Judgments
Our contracts with customers may contain multiple promises to transfer products and services as described above. Determining whether products and services are considered distinct may require significant judgment.
Determining the standalone selling price ("SSP") for each distinct performance obligation requires judgment. We allocate revenue to all distinct performance obligations based on their relative SSPs. When available, we use observable prices to determine SSPs. When observable prices are not available, SSPs are established that reflect our best estimates of what the selling prices which have been determined using best estimate of sellingthe performance obligations would be if they were sold regularly on a stand-alone basis. Our process for estimating SSPs without observable prices considers multiple factors that may vary depending upon the facts and circumstances related to each performance obligation including, market data or the estimated cost of providing the products or services.
Determining the revenue recognition period for services requires judgment. The transaction price (BESP), as we have not been able to establish vendor specific objective evidence (VSOE) or obtain relevant third party evidence (TPE). Revenue allocated to the app and unspecified software upgradesCloud Services is then deferred and recognized on a straight-line basis over the period in which we expect to provide the upgrades, which is the estimated lifeterm of the robot.Cloud Services. Other services and support are recognized over their service periods.
Sales to retailers of consumer robots are typically subject to agreements allowing for limited rights of return, rebatesEstimating variable consideration such as product returns and price protection.sales incentives requires judgment. We also provide limited rights of returns for direct-to-consumer sales generated through our on-lineits online stores and certain internationalresellers and distributors. Accordingly, we reduce revenueWe record an allowance for our estimates of liabilities for these rights of return, rebates and price protection, as well as discounts and promotions, at the time the related sale is recorded. The estimates for rights of return are directlyproduct returns based on specific terms and conditions included in the customer agreements historical returns experience and various other assumptions that we believe are reasonable under the circumstances. In the case of new product introductions, the estimates for returns applied to the new products are based upon the estimates for the most similar predecessor products until such time that we have enough actual returns experience for the new products, which is typically two holiday return cycles. At that time, we incorporate that data into the development of returns estimates for the new products. We update our analysis of returns on a quarterly basis. If actual returns differ significantly from our estimates, or if modifications to individual customer agreements are entered into that impact their rights of returns, such differences could result in an adjustment to previously established reserves and could have a material impact, either favorably or unfavorably, on our results of operations for the period in which the actual returns become known or the agreement is modified. In 2016, we began selling to one domestic distributor under an agreement that provides product return privileges. As a result, we recognize revenue from sales to this distributor when the product is resold by the distributor. The estimates and adjustments for rebates and price protection are based on specific programs, expected usage and historical experience. Actual results could differ from these estimates. As of December 30, 2017, we have reserves for product returns of $42.7 million, discounts and promotions of $58.2 million and price protection of $3.1 million. As of December 31, 2016, we had reserves for product returns of $27.7 million, discounts and promotions of $22.1 million and price protection of $1.5 million.
Prior to our divestiture of the defense and security business unit in April 2016 (see Note 4), we generated minimal revenue from government contracts. Under cost-plus-fixed-fee (CPFF) type contracts, we recognized revenue based on costs incurred plus a pro rata portion of the total fixed fee. Costs incurred included labor and material that were directly associated with individual CPFF contracts plus indirect overhead and general and administrative type costs based upon billing rates we

submitted to the Defense Contract Management Agency (DCMA). Annually, we submitted final indirect billing rates to DCMA based upon actual costs incurred throughout the year. In the situation where our final actual billing rates are greater than the estimated rates used, we record a cumulative revenue adjustment in the period in which the rate differential is collected from the customer. These final billing rates are subject to audit by the Defense Contract Audit Agency (DCAA), which can occur several years after the final billing rates are submitted and may result in material adjustments to revenue recognized based on estimated final billing rates. As of December 30, 2017, fiscal year 2016 is open for audit by DCAA. In the situation where our anticipated actual billing rates will be lower than the provisional rates used, we record a cumulative revenue adjustment in the period in which the rate differential is identified. Revenue on firm fixed price (FFP) contracts was recognized using the percentage-of-completion method. For government product FFP contracts, revenue was recognized as the product was shipped or in accordance with the contract terms. Costs and estimated gross margins on contracts were recorded as revenue as work was performed based on the percentage that incurred costs compared to estimated total costs utilizing the most recent estimates of costs and funding. Revenue earned in excess of billings, if any, was recorded as unbilled revenue. Billings in excess of revenue earned, if any, were recorded as deferred revenue.
Business Combinations
We account for transactions that represent business combinations under the acquisition method of accounting. We allocate the total consideration paid for each acquisition to the assets we acquire and liabilities we assume based on their fair values as of the date of acquisition, including identifiable intangible assets. We base the fair value of identifiable intangible assets acquired in a business combination on valuations that use information and assumptions determined by us and which consider our best estimates of inputs and assumptions that a market participant would use. While we use our best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the business combination date, our estimates and assumptions are inherently uncertain and subject to refinement. As a result, during the measurement period, which is generally one year from the acquisition date, any adjustment to the assets acquired and liabilities assumed is recorded against goodwill in the period in which the amount is determined. Any adjustment identified subsequent to the measurement period is included in operating results in the period in which the amount is determined.
Inventory
Inventory is stated at the lower of cost or net realizable value with cost being determined using the first-in, first-out (FIFO) method. We maintain a reserve for inventory items to provide for an estimated amount of excess or obsolete inventory.
Warranty
We typically provide a one-year warranty (with the exception of European consumer products, which typically have a two-year warranty period) against defects in materials and workmanship and will either repair the goods, provide replacement products at no charge to the customer or refund amounts to the customer for defective products. We record estimated warranty costs, based on historical experience by product,and our expectation of future returns. In addition, we may provide other credits or incentives which are accounted for as variable consideration when estimating the amount of revenue to recognize. Where appropriate, these estimates take into consideration relevant factors such as our historical experience, current contractual requirements, specific known market events and forecasted inventory level in the channels. Returns and credits are estimated at the time we recognize product revenue. Actual results could differ from these estimates, which could cause increases or decreases to our warranty reserves in future periods.
Goodwillof sale and Other Long-Lived Assets
Goodwill represents the excess of the purchase price in a business combination over the fair value of the net tangible and intangible assets acquired. Goodwill is not amortized but rather is assessed for impairmentupdated at the end of each reporting unit level (operating segment or one level below an operating segment) annually or more frequently if we believe indicators of impairment exist. Goodwill impairment, if any, is determined by comparing the reporting unit's fair value to its carrying value. An impairment loss is recognized in an amount equal to the excess of the reporting unit's carrying value over its fair value, up to the amount of goodwill allocated to the reporting unit.period as additional information becomes available. We complete the annual impairment evaluation during the fourth quarter each year.
Other long-lived assets consist principally of completed technology, tradename, customer relationships, reacquired distribution rights and non-competition agreements. Reacquired distribution rights are amortized on an accelerated basis while all other intangible assets are amortized over their respective estimated useful lives on a straight-line basis, consistent with the pattern in which the economic benefits are being utilized.
We periodicallyregularly evaluate the recoverabilityadequacy of other long-lived assets whenever events and changes in circumstances, such as reductions in demand or significant economic slowdowns in the industry, indicate that the carrying amount of an asset may not be fully recoverable. When indicators of impairment are present, the carrying values of the asset group are evaluated in relation to the future undiscounted cash flows of the underlying business. The net book value of the underlying asset is adjusted to fair value if the sum of the expected discounted cash flows is less than book value. Fair values are based onour estimates of market prices and assumptions concerning the amount and timing of estimated future cash flows and assumed discount rates, reflecting varying degrees of perceived risk.
The impairment assessment of goodwillfor product returns and other long-lived assets involves significantcredits and incentives. Future market conditions and product transitions may require us to take action to change such programs and related estimates. When the variables used to estimate these reserves change, or if actual results differ significantly from the estimates, and assumptions, which maywe would be unpredictable and inherently uncertain. These estimates and assumptions include identification of reporting units and

asset groups, long-term growth rates, profitability, estimated useful lives, comparable market multiples, and discount rates. Any changes in these assumptions could impactrequired to increase or reduce revenue to reflect the result of the impairment assessment.
Stock-Based Compensation
We account for stock-based compensation through recognition of the fair value of the stock-based compensation as a charge against earnings. The fair value of employee stock options is estimated at the grant date using the Black-Scholes option-pricing model. The fair value for restricted stock awards, time-based restricted stock units and performance-based restricted stock units is based on the closing share price of our common stock on the date of grant. For performance-based restricted stock units, the compensation cost is recognized based on the number of units expected to vest upon the achievement of the performance conditions. We recognize stock-based compensation as an expense over the requisite service period. We have elected to account for forfeitures as they occur, rather than applying an estimated forfeiture rate, following our adoption of ASU 2016-09 in the first quarter of 2017.impact.
Accounting for Income Taxes
We are subject to income taxes in the United States and other foreign jurisdictions. Significant judgment is required in determining our provision for income taxes, and income tax assets and liabilities, including evaluating uncertainties in the application of accounting principles and complex tax laws.
Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis using enacted tax rates in effect in the years in which those temporary differences are expected to be recovered or settled in each jurisdiction. A valuation allowance is provided if, based upon the weight of available evidence, it is more likely than not

that the related benefits will not be realized. The CompanyWe regularly reviewsreview the deferred tax assets for recoverability considering historical profitability, projected future taxable income, future reversals of existing taxable temporary differences, as well as feasible tax planning strategies in each jurisdiction. As of December 30, 2017, the Company recorded a valuation allowance of $0.8 million for certain foreign deferred tax assets for which the Company believes do not meet the "more likely than not" criteria for recognition.
The Company reportsWe report a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The Company recognizes interestWe evaluate uncertain tax positions on a quarterly basis and penalties, if any, related to unrecognized tax benefits in the income tax provision.

Table of foreign earnings. We have estimated our provision for income taxes in accordance with the Act and guidance available as of the date of this filing and as a result have recorded a one-time income tax provision of $11.9 million in the fourth quarter of 2017, the period in which the legislation was enacted. The one-time income tax provision includes $8.9 million related to the remeasurement of certain deferred tax assets and liabilities based on the tax rates at which they are expected to reverse in the future. The one-time income tax expense also includes a provisional amount of $3.0 million related to the one-time transition tax on the mandatory deemed repatriation of foreign earnings.Contents
On December 22, 2017, Staff Accounting Bulletin No. 118 (SAB 118) was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. In accordance with SAB 118, we have determined that the $3.0 million of current income tax provision recorded relating to the transition tax on the mandatory deemed repatriation of foreign earnings was a provisional amount and a reasonable estimate at December 30, 2017. Additional information and analysis is necessary to complete the calculation and accounting relating to the transition tax on the mandatory deemed repatriation of foreign earnings. Any subsequent adjustments to this amount will be recorded to current income tax provision during the measurement period which is not expected to extend beyond one year from the enactment date.

Revenue
We currentlyprimarily derive our revenue from product sales. Untilsales through distributor and retail sales channels, as well as the divestiture of the defenseonline store on our website and security business unit in April 2016, we also generated minimal revenue from government and commercial research and development contracts.
For the fiscal years ended December 30, 2017, December 31, 2016 and January 2, 2016, approximately 62.7%, 72.8% and 76.6%, respectively, of our consumer robots revenue resulted from sales to 15 customers, which were comprised of both domestic retailers and international distributors. Direct-to-consumer revenue generated through our domestic and international on-line stores accounted for 4.1%, 5.1% and 6.1% of our consumer robots revenue for the fiscal years ended December 30, 2017, December 31, 2016 and January 2, 2016, respectively. We typically sell our recently launched products direct on-line, and then subsequently offer these products through other channels of distribution.
For the fiscal years ended December 30, 2017, December 31, 2016 and January 2, 2016, sales to non-U.S. customers accounted for 48.8%, 51.2% and 56.0% of total revenue, respectively.

Revenue increased 33.8% to $883.9 million in fiscal 2017 from $660.6 million in fiscal 2016. Revenue increased approximately $227.8 million, or 34.7%, in our consumer business while revenue decreased $3.1 million in our defense and security business as a result of its sale in April 2016. The $227.8 million increase in revenue from our consumer business was driven by a 25.7% increase in units shipped and a 10.8% increase in average selling price. In fiscal 2017, domestic consumer revenue increased $133.2 million, or 41.8%, and international consumer revenue increased $94.6 million, or 28.1%, compared to fiscal 2016. Total consumer robots shipped in fiscal 2017 were approximately 3,698,000 units compared to approximately

2,943,000 units in fiscal 2016. The increase in domestic consumer robot revenue was primarily attributable to increased sales as a result of investments in advertising media and national promotions and further adoption of our robots, particularly our Roomba 900 and Roomba 600 series robots. During 2017, we recorded a net benefit to revenue and income before income taxes of $2.2 million related to adjustments to our product returns reserves compared to a net benefit to revenue and income before income taxes of $3.5 million during fiscal 2016. The net adjustments recorded in each period resulted from lower product returns experience as compared to estimates used to establish reserves in prior periods.

The increase in average gross selling price was primarily driven by a 15.4% growth in sales of our mid and premium tier floor cleaning robots. In fiscal 2021, international revenue increased $125.1 million, or 18.2% due primarily to 21.9% growth in EMEA and a 15.2% increase in Japan, while domestic revenue increased $9.5 million, or 1.3%. Our direct-to-consumer revenue growth of 24.2% to $187.4 million, or 12.0% of total revenue, reflected continued expansion of this channel as we invested in enhancing the online buying experience and upgrading our digital marketing capabilities.
Year ended January 2, 2021 as compared to the year ended December 28, 2019
Revenue increased 17.8% to $1,430.4 million in fiscal 2020 from $1,214.0 million in fiscal 2019. Although the initial impact of the COVID-19 pandemic on our sales and manufacturing supply chain activities during the first quarter of 2020 resulted in a revenue decline, demand for our robots increased substantially during the remainder of fiscal 2020 as maintaining a clean home took on greater prominence during the pandemic. We saw significant growth in our direct-to-consumer sales generating 11% of total fiscal 2020 revenue, up from approximately 6% in 2019. The increase in revenue was primarily driven by strong demand with a 10.1% increase in total units shipped in fiscal 2016 were2020 as compared to fiscal 2019.

In fiscal 2020, domestic consumer robots revenue was primarily attributable to increased sales as a result of significant investments in advertising media and national promotions as well as$141.0 million, or 23.4%, while international revenue increased sales of the Roomba 900 series robots. Roomba 980 launched in late 2015, with a full year of revenue included in fiscal 2016. Roomba 960 was introduced in the third quarter of 2016. International consumer robots revenue grew 3.7% primarily due to our execution of successful marketing programs in those markets, as well as stronger overseas economies. During 2016, we recorded a net benefit to revenue and income before income taxes of $3.5$75.4 million, related to adjustments to our product returns reserves compared to a net benefit to revenue and income before income taxes of $6.9 million during fiscal 2015. The net adjustments recorded in each period resulted from lower product returns experienceor 12.3%, as compared to estimates usedfiscal 2019. The international revenue growth was driven by increases in revenue from Japan and EMEA of 20% and 8%, respectively, compared to establish reserves in prior periods. Partially offsetting these items in 2016 was a net reduction to revenue and income before income taxes of $6.4 million for pricing support to customers in response to changing market conditions.2019.
Cost of Product Revenue
Cost of product revenue includes theprimarily consists of product cost, of raw materials and labor that go into the development and manufactureincluding costs of our products as well ascontract manufacturers for production and component product costs, inbound and outbound freight, import duties, tariffs, logistics and fulfillment costs, manufacturing overheadand tooling equipment depreciation, hosting costs such as manufacturing engineering, quality assurance, logistics,and warranty third-party consulting, travel and associated direct material costs. Additionally,cost. In addition, we include overheadother expenses such as indirect engineering labor, occupancy costs associated with the project resources, engineering toolssupply chain logistics including personnel-related expenses of salaries and supplies and program management expenses. Raw material costs, which are our most significant cost items, can fluctuate materially on a periodic basis, although many components have been historically stable. Additionally, unit costs can vary significantly depending on the mix of products sold. There can be no assurance that our costs of raw materials will not increase. Labor costs also comprise a significant portion of our cost of revenue.related costs. We outsource the manufacture of our consumer robotsproducts to contract manufacturers in China.southern China and began to diversify our supply chain by adding manufacturing capacity in Malaysia starting November 2019. During 2021, we continued to scale production in Malaysia by qualifying additional contract manufacturers. While labor costs in Chinathese regions traditionally have been favorable compared to labor costs elsewhere in the world, including the United States, they have been increasing for the last few years.years, especially with supply chain challenges driven by the COVID-19 pandemic. In addition, fluctuationsbecause our purchase contract with our contract manufacturers in China and Malaysia are typically denominated in U.S. dollars, changes in currency exchange rates couldmay impact our suppliers and increase the cost of labor. Consequently, the labor costs for our consumer robots could increase in the future.prices.

Year ended December 30, 2017 as compared to the year ended December 31, 2016
Cost of product revenue increased $100.3 million, or 29.7% to $438.1 million in fiscal 2017, compared to $337.8 million in fiscal 2016. The increase is primarily due to the 33.8% increase in revenue as well as the impact from our acquisitions of the iRobot-related distribution business of SODC in April 2017 and Robopolis in October 2017.
Year ended December 31, 2016January 1, 2022 as compared to the year ended January 2, 20162021

The cost of product revenue in fiscal 2021 included $48.3 million in tariff costs, whereas in fiscal 2020, we recognized a benefit of $36.5 million from tariff refunds. The increase in cost of product revenue is also attributable to the 9.4% increase in revenue, as well as higher costs associated with the global supply chain challenges including increased oceanic transport and air freight expenses and higher raw materials and component costs associated with limited semiconductor chip availability. We anticipate these challenges and higher costs to continue at least through the first half of fiscal 2022.
Year ended January 2, 2021 as compared to the year ended December 28, 2019
Cost of product revenue increased $99.9 million, or 15.2%, to $758.2 million in fiscal 2020, compared to $658.4 million in fiscal 2019. The increase is primarily due to the 7.1%17.8% increase in revenue, as well as increases in warranty and increasedrework costs, associated with assuming warranty liabilityoffset by the recognition of the tariff refunds of approximately $36.5 million for tariffs paid in 2018 and 2019. On April 24, 2020, we were granted a temporary exclusion, as extended in August 2020, from Section 301 List 3 tariffs by the United States Trade Representative, which temporarily eliminated the 25% tariff on Roomba products imported from China as part of our strategy in that market.

Research and Development
Research and development expenses consist primarily of:
salaries and related costs for our engineers;
contractors and consulting expenses;
costs of components and test equipment used for high technology components used in product, tooling and prototype development; and
costs of test equipment used during product development; and
occupancy and other overhead costs.
Our research and development team develops new software and hardware products as well as improves and enhances our existing software and hardware products to address customer demands and emerging trends. We have significantly expanded our research and development capabilitiesin software intelligence, resulting in recent upgrades to the Genius Home Intelligence platform, along with ongoing investment in AI, home understanding and expect to continue to expand these capabilities in the future.machine vision technologies. We are committed to consistently maintaining theour high level of innovative design and development of new products as we strive to enhance our ability to serve our existing consumer markets as well as new markets for robots.

Working Capital and Capital Expenditure Needs
We currently have no material cash commitments, except for normal recurring trade payables, expense accruals, capital expenditures and operating leases, all of which we anticipate funding through working capital and funds provided by operating activities and our existing working capital line of credit.activities. We do not currently anticipate significant investment in property, plant and equipment, and we believe that our outsourced approach to manufacturing provides us with flexibility in both managing inventory levels and financing our inventory. We believe our existing cash and cash equivalents, short-term investments, cash provided by operating activities, and funds available through our working capital line of credit facility will be sufficient to meet our working capital and capital expenditure needs over at least the next twelve months. In the event that our revenue plan does not meet our expectations, we may eliminate or curtail expenditures to mitigate the impact on our working capital. Our future capital requirements will depend on many factors, including our rate of revenue growth or decline, the expansion or contraction of our marketing and sales activities, the timing and extent of spending to support product development efforts, the timing of introductions of new products and enhancements to existing products, the acquisition of new capabilities or technologies, and the continuing market acceptance of our products and services.services, and the impact of COVID-19 on our business. Moreover, to the extent that existing cash and cash equivalents, short-term investments, cash from operations, and cash from short-term borrowing are insufficient to fund our future activities, we may need to raise additional funds through public or private equity or debt financing. As part of our business strategy, we may consider additional acquisitions of companies, technologies and products, which could also require us to seek additional equity or debt financing. Additional funds may not be available on terms favorable to us or at all.

ITEM 7A.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK


Exchange Rate Sensitivity
Our international revenue and expenses are denominated in multiple currencies, including Japanese Yen,British Pounds, Canadian Dollars, Chinese Yuan Renminbi, Euros and Euros.Japanese Yen. As such, we have exposure to adverse changes in exchange rates associated with the revenue and operating expenses of our foreign operations. Any fluctuations in other currencies will have minimal direct impact on our international revenue.
In addition to international business conducted in foreign currencies, we have a significant amount of international revenue denominated in U.S. dollars. As the U.S. dollar strengthens or weakens against other currencies, our international distributors may be impacted, which could affect their profitability and our ability to maintain current pricing levels on our international consumer products.
We regularly monitor the forecast of non-U.S. dollar revenue and expenses and the level of non-U.S. dollar monetary asset and liability balances to determine if any actions, including possibly entering into foreign currency forward contracts, or swaps, should be taken to minimize the impact of fluctuating exchange rates on our results of operations. Periodically, we enter into forward exchange contracts to hedge against foreign currency fluctuations. These contracts may or may not be designated as cash flow hedges for accounting purposes. We use cash flow hedges primarily to reduce the effects of foreign exchange rate changes on purchasesales in Euros and sales, primarily in Japanese YenYen. These contracts typically have maturities of three years or less. At January 1, 2022 and Euros. At December 30, 2017 and December 31, 2016,January 2, 2021, we had outstanding cash flow hedges with a total notional value of $73.7$423.3 million and $0.0$431.9 million, respectively.
We also enter into economic hedges that are not designated as hedges from an accounting standpoint to reduce or eliminate the effects of foreign exchange rate changes typically related to short term trade receivables and payables. These contracts have maturities of twotwelve months or less. At December 30, 2017January 1, 2022 and December 31, 2016,January 2, 2021, we had outstanding economic hedges with a total notional value of $36.6$325.4 million and $8.1$192.2 million, respectively.

Interest Rate Sensitivity
At December 30, 2017,January 1, 2022, we had unrestricted cash and cash equivalents of $128.6 million and short term investments of $37.2$201.5 million. The unrestricted cash and cash equivalents are held for working capital purposes. We do not enter into investments for trading or speculative purposes. Some of the securities in which we invest, however, may be subject to market risk. This means that a change in prevailing interest rates may cause the fair market value of the investment to fluctuate. To minimize this risk in the future, we intendhave the ability to maintain our portfolio of cash equivalentsinvest in a variety of securities including, commercial paper, money market funds, debt securities and certificates of deposit. Due to the short-term nature of these investments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. As of December 30, 2017,January 1, 2022, all of our cash and cash equivalents were held in demand deposits and money market accounts, and government bonds.funds.

iRobot Corporation:


Opinions on the Financial Statements and Internal Control over Financial Reporting


We have audited the accompanying consolidated balance sheets of iRobot Corporation and its subsidiaries (the “Company”) as of December 30, 2017January 1, 2022 and December 31, 2016,January 2, 2021, and the related consolidated statements of income, of comprehensive income, of stockholders’ equity and of cash flows for each of the three years in the period ended December 30, 2017,January 1, 2022, including the related notes (collectively referred to as the "consolidated“consolidated financial statements"statements”). We also have audited the Company's internal control over financial reporting as of December 30, 2017,January 1, 2022, 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 30, 2017January 1, 2022 and December 31, 2016,January 2, 2021, and the results of theirits operations and theirits cash flows for each of the three years in the period ended December 30, 2017January 1, 2022 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 30, 2017,January 1, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.


Basis for Opinions


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 Management'sManagement’s Report on Internal Control overOver Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and 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")(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.

As described in Management’s Report on Internal Control over Financial Reporting, management has excluded iRobot Japan G.K. and iRobot France SAS (formerly known as Robopolis SAS) from its assessment of internal control over financial reporting as of December 30, 2017, because they were acquired by the Company in purchase business combinations during fiscal 2017. We have also excluded iRobot Japan G.K. and iRobot France SAS (formerly known as Robopolis SAS) from our audit of internal control over financial reporting. iRobot Japan G.K. and iRobot France SAS (formerly known as Robopolis SAS) are wholly-owned subsidiaries whose total assets and total revenues excluded from management’s assessment and our audit of internal control over financial reporting collectively represent approximately 8.3% and 23.9% of total assets, respectively and approximately 9.9% and 13.0% of total revenues, respectively, of the related consolidated financial statement amounts as of and for the year ended December 30, 2017.



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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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 matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Allowance for Product Returns

As described in Notes 2 and 3 to the consolidated financial statements, the Company provides limited rights of returns for direct-to-consumer sales generated through its on-line stores and certain resellers and distributors. The Company records an allowance for product returns based on specific terms and conditions included in the customer agreements or based on historical experience and management’s expectation of future returns. Returns and credits are estimated at the time of sale and updated at the end of each reporting period as additional information becomes available. As of January 1, 2022, the Company had reserves for product returns of $56.8 million.

The principal considerations for our determination that performing procedures relating to the allowance for product returns is a critical audit matter are (i) the significant judgment by management in developing the allowance for product returns related to management’s expectation of future returns; and (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating audit evidence related to the allowance for product returns and management’s expectation of future returns.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the revenue recognition process, including the estimation of the allowance for product returns. These procedures also included, among others (i) testing management’s process for developing the allowance for product returns, (ii) evaluating the appropriateness of management’s approach to calculate the allowance for product returns, (iii) testing the completeness and accuracy of underlying historical sales and returns data used by management to develop the allowance for product returns, and (iv) evaluating the reasonableness of management’s expectation of future returns based on historical experience by customer by product.

During the first quarter of 2021, the Company received net proceeds of $51.5 million related to the sale of Teladoc shares with gross proceeds of $60.1 million, net of settlement payment of $8.6 million for the related economic hedge.
Allowance for Credit Losses

Inventory primarily consists of finished goods and, variousto a lesser extent, components, which are purchased from contract manufacturers. Inventory is stated at the lower of cost or net realizable value with cost being determined using the standard cost method, which approximates actual costs determined on the first-in, first-out basis. Inventory costs primarily consist of materials, inbound freight, import duties, tariffs, and other assumptions that thehandling fees. The Company believes are reasonable under the circumstances.

Tariff Refunds
From September 2018 until April 2020, our Roomba products were subject to Section 301 tariffs. In April 2020, we were granted a temporary exclusion from Section 301 List 3 tariffs by the United States Trade Representative ("USTR"). This exclusion, as extended in August 2020, eliminated the 25% tariff on Roomba products imported from China until such time thatDecember 31, 2020 and entitled us to a refund of approximately $57.0 million in tariffs paid since the Company has enough actual returns experience fordate the new products, which is typically two holiday return cycles. At that time, the Company incorporates that data into the development of returns estimates for the new products.Section 301 List 3 tariffs were imposed. The Company updates its analysisrecognized a benefit of returns on a quarterly basis. If actual returns differ significantly$36.5 million from tariff refund during fiscal year 2020. Effective January 1, 2021, the 25% Section 301 tariff again applies to our Roomba products imported from China. For the fiscal year ended January 1, 2022, the incremental Section 301 tariff cost was $48.3 million.

Capitalization of Cloud Computing Arrangements

Beginning in an adjustment to previously established reservesfiscal 2020, and could have a material impact, either favorably or unfavorably, on the Company’s results of operations for the period in which the actual returns become known or the agreement is modified. In 2016,continuing through fiscal 2021, the Company began selling to one domestic distributor underinvesting and implementing various new direct-to-consumer and marketing technology and tools. Implementation costs incurred during the application development stage are capitalized until the software is ready for its intended use. The costs are then amortized on a straight-line basis over the term of the associated hosting arrangement and are recognized as an agreement that provides product return privileges. As a result,operating expense within the Company recognizes revenue from sales to this distributor when the product is resold by the distributor. The estimates and adjustments for rebates and price protection are based on specific programs, expected usage and historical experience. Actual results could differ from these estimates. Asconsolidated statements of December 30, 2017, the Company has reserves for product returns of $42.7 million, discounts and promotions of $58.2income. Capitalized costs were $7.4 million and price protection$0.7 million as of $3.1 million. AsJanuary 1, 2022 and January 2, 2021, respectively, and are reported as a component of December 31, 2016, the Company had reserves for product returns of $27.7 million, discounts and promotions of $22.1 million and price protection of $1.5 million.
Prior toother assets on the Company's divestiture of the defense and security business unit in April 2016 (see Note 4), the Company generated minimal revenue from government contracts. Under cost-plus-fixed-fee (CPFF) type contracts, the Company recognized revenue based on costs incurred plus a pro rata portion of the total fixed fee. Costs incurred included labor and material that were directly associated with individual CPFF contracts plus indirect overhead and general and administrative type costs based upon billing rates submitted by the Company to the Defense Contract Management Agency (DCMA)consolidated balance sheets. Annually, the Company submitted final indirect billing rates to DCMA based upon actual costs incurred throughout the year. In the situation where the Company’s final actual billing rates are greater than the estimated rates used, the Company records a cumulative revenue adjustment in the period in which the rate differential is collected from the customer. These final billing rates are subject to audit by the Defense Contract Audit Agency (DCAA), which can occur several years after the final billing rates are submitted and may result in material adjustments to revenue recognized based on estimated final billing rates. As of December 30, 2017, fiscal year 2016 is open for audit by DCAA. In the situation where the Company’s anticipated actual billing rates will be lower than the provisional rates used, the Company records a cumulative revenue adjustment in the period in which the rate differential is identified. Revenue on firm fixed price (FFP) contracts was recognized using the percentage-of-completion method. For government product FFP contracts, revenue was recognized as the product was shipped or in accordance with the contract terms. Costs and estimated gross margins on contracts were recorded as revenue as work was performed based on the percentage that incurred costs compared to estimated total costs utilizing the most recent estimates of costs and funding. Revenue earned in excess of billings, if any, was recorded as unbilled revenue. Billings in excess of revenue earned, if any, were recorded as deferred revenue.
Business Combinations
The Company accounts for transactions that represent business combinations under the acquisition method of accounting. The Company allocates the total consideration paid forpurchase price of each acquisition to the tangible and intangible assets it acquiresacquired and liabilities it assumesassumed based on their estimated fair values as of the date of acquisition, including identifiable intangible assets.  The Company basesacquisition. Goodwill is measured as the fairexcess of the purchase price over the value of identifiable intangiblenet identified assets acquired in a business combination on valuations that use information and assumptions determined by management and which consider management’s best estimates of inputs and assumptions that a market participant would use.acquired. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired, and liabilities assumed, and contingent consideration, where applicable, at the business combinationacquisition date, its estimates and assumptions are inherently uncertain and subject to refinement. As a result, during the measurement period, which is generally one year from the acquisition date, any adjustment to the assets acquired and liabilities assumed is recorded against goodwill in the period in which the amount is determined. Any adjustment identified subsequent to the measurement period or the Company's final determination of estimated fair value, whichever comes first, is included in operating results in the period in which the amountadjustment is determined.
Cash and Cash Equivalents
The Company considers all highly liquid investments with an original or remaining maturity of three months or less at the time of purchase to be cash equivalents. The Company invests its excess cash primarily in money market funds or savings accounts of major financial institutions. Accordingly, its cash equivalents are subject to minimal credit and market risk. At December 30, 2017 and December 31, 2016, cash equivalents were comprised of money market funds totaling $3.2 million and $157.0 million, respectively. These cash equivalents are carried at cost, which approximates fair value.

Inventory
Inventory is stated at the lower of cost or net realizable value with cost being determined using the first-in, first-out (FIFO) method. The Company maintains a reserve for inventory items to provide for an estimated amount of excess or obsolete inventory.
Warranty
The Company typically provides a one-year warranty (with the exception of European consumer products, which typically have a two-year warranty period) against defects in materials and workmanship and will either repair the goods, provide replacement products at no charge to the customer or refund amounts to the customer for defective products. The Company records estimated warranty costs, based on historical experience by product, at the time revenue is recognized.

Actual results could differ from these estimates, which could cause increases or decreases to the warranty reserves in future periods.
Property and Equipment
Property and equipment are recorded at cost and consist primarily of computer equipment, leasehold improvements, business applications software and machinery. Depreciation is computed using the straight-line method over the estimated useful lives as follows:
Estimated Useful Life
Computer and research equipment2-5 years
Furniture5
Machinery2-5
Tooling2-5
Business applications software5-7
Capital leases and leasehold improvementsLesser of economic benefit period or term of lease
Expenditures for additions, renewals and betterments of property and equipment are capitalized. Expenditures for repairs and maintenance are charged to expense as incurred. As assets are retired or sold, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is credited or charged to operations.
Goodwill and Other Long-Lived Assets
Goodwill represents the excess of the purchase price in a business combination over the fair value of the net tangible and intangible assets acquired. Goodwill is not amortized but rather is assessed for impairment at the reporting unit level (operating segment or one level below an operating segment) annually during the fourth quarter of each fiscal year or more frequently if the Company believes indicators of impairment exist. Goodwill impairment, if any, is determined by comparing the reporting unit's fair value to its carrying value. An impairment loss is recognized in an amount equal to the excess of the reporting unit's carrying value over its fair value, up to the amount of goodwill allocated to the reporting unit. The Company completes the annual impairment evaluation during the fourth quarter each year.
Other long-lived assets primarily consist principally of completed technology, tradename, customer relationships, reacquired distribution rightsproperty and non-competition agreements. Reacquired distribution rights are amortized on an accelerated basis while all otherequipment, operating lease right-of-use assets and intangible assets are amortized over their respective estimated useful lives on a straight-line basis, consistent with the pattern in which the economic benefits are being utilized.
assets. The Company periodically evaluates the recoverability of other long-lived assets whenever events and changes in circumstances, such as reductions in demand or significant economic slowdowns in the industry, indicate that the carrying amount of an asset may not be fully recoverable. When indicators of impairment are present, the carrying values of the asset group are evaluated in relation to the future undiscounted cash flows of the underlying business. The net book value of the underlying asset is adjusted to fair value if the sum of the expected discounted cash flows is less than book value. Fair values are based on estimates of market prices and assumptions concerning the amount and timing of estimated future cash flows and assumed discount rates, reflecting varying degrees of perceived risk.
The impairment assessment of goodwill and other long-lived assets involves significant estimates and assumptions, which may be unpredictable and inherently uncertain. These estimates and assumptions include identification of reporting units and asset groups, long-term growth rates, profitability, estimated useful lives, comparable market multiples, and discount rates. Any changes in these assumptions could impact the result of the impairment assessment. There was no impairment of goodwill or other long-lived assets during fiscal 2021, 2020 and 2019.
Other AssetsStrategic Investments
The Company holds non-marketable equity securities as part of its strategic investments portfolio. The Company classifies the majority of these securities as equity securities without readily determinable fair values and measures these investments at cost, less any impairment, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. These investments are valued using significant unobservable inputs or data in an inactive market and the valuation requires the Company's judgment due to the absence of market prices and inherent lack of liquidity. The Company monitors non-marketable equity investments for impairment indicators, such as deterioration in the investee's financial condition and business forecasts and lower valuations in recent or proposed financings. The estimated fair value is based on quantitative and qualitative factors including, but not limited to, subsequent financing activities by the investee and projected discounted cash flows. Changes in fair value of non-marketable equity investments are recorded in other income, net on the consolidated statements of income. At December 30, 2017January 1, 2022 and December 31, 2016,January 2, 2021, the Company's equity securities without readily determinable fair values totaled $16.3 million and $17.4 million, respectively, and are included in other assets consisted primarily of cost and an equity method investment totaling $14.2 million and $12.9 million, respectively. The Company regularly monitors these investments to determine if facts and circumstances have changed in a manner that would require a change in accounting methodology. Additionally,on the Company regularly evaluates whether or not these investments have been impaired by considering such factors as economic environment, market conditions, operational performance and other specific factors relating to the businesses underlying the investments. If any such impairment is identified, a reduction in the carrying value of the investments would be recorded at that time.

Warranty
The Company generally provides a one-year warranty on all of its products except in countries where a two-year warranty is required against defects in materials and workmanship. The Company's standard warranty provides for repair or replacement of the associated products during the warranty period. The Company records estimated warranty costs in the period the related revenue is recognized based on historical experience, expectations of future costs to repair or replace including freight and knowledge of specific product failures outside the Company's historical experience. Actual results could differ from these estimates, which could cause increases or decreases to the warranty reserves in future periods.
Financial Instruments and Hedging Activities
The Company utilizes derivative instruments to hedge specificpartially offset its financial risks includingto foreign exchange risk. The Company does not engage in speculative hedging activity. In order to account for a derivative instrument as a cash flow hedge, specific criteria must be met, including: (i) ensuring at the inception of the hedge that formal documentation exists for both the hedging relationship and the entity’s risk management objective and strategy for undertaking the hedge and (ii) at the inception of the hedge and on an ongoing basis, the hedging relationship is expected to be highly effective in achieving offsetting changes in fair value attributed to the hedged risk during the period that the hedge is designated. Further, anCash flow hedge amounts that are included in the assessment of hedge effectiveness are deferred in accumulated other comprehensive income (loss) until the hedged item is required whenever financial statements or earningsrecognized in earnings. Deferred gains and losses associated with cash flow hedges are reported.recognized as a component of net sales in the same period as the related revenue is recognized.

Any ineffective portion of the derivatives designated as cash flow hedges isforeign currency exchange gains and losses generated by the remeasurement of certain assets and liabilities denominated in non-functional currencies. Changes in fair value are recognized in current earnings.other income, net, in the consolidated statements of income.
Fair Value Measurements
The Company accounts for certain assets and liabilities at fair value. The fair value is established based on a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. These tiers include:
Level 1 - observable inputs such as quoted prices for identical instruments in active markets;
Level 2 - inputs other than quoted prices in active markets that are either directly or indirectly observable; and
Level 3 - unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.
Stock-Based Compensation
The Company accounts for stock-based compensation through recognition of the fair value of the stock-based compensation as a charge against earnings. The fair value of employee stock options is estimated at the grant date using the Black-Scholes option-pricing model. The fair value for restricted stock awards, time-based restricted stock units and performance-based restricted stock units is based on the closing share price of the Company's common stock on the date of grant. For performance-based restricted stock units, the compensation cost is recognized based on the number of units expected to vest upon the achievement of the performance conditions. The Company recognizes stock-based compensation as an expense on a straight-line basis, over the requisite service period. The Company has elected to accountaccounts for forfeitures as they occur, rather than applying an estimated forfeiture rate, following its adoption of ASU 2016-09 in the first quarter of 2017.rate.
Research and Development
Costs incurred in the research and development of the Company’s products are expensed as incurred.
Internal Use SoftwareAdvertising Expense
The Company capitalizesAdvertising costs associated with the developmentare expensed as incurred and implementation of software for internal use. At December 30, 2017 and December 31, 2016, the Company had $12.8 million and $9.5 million, respectively, of costs related to enterprise-wide software included in fixed assets. Capitalized costs are being amortized over the assets’ estimated useful lives. The Company has recorded $1.5 million, $0.4 millionselling and $0.7 million of amortization expense for the years ended December 30, 2017, December 31, 2016 and January 2, 2016, respectively.

Income Taxes
Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis using enacted tax rates in effect in the years in which those temporary differences are expected to be recovered or settled in each jurisdiction. A valuation allowance is provided if, based upon the weight of available evidence, it is more likely than not that the related benefits will not be realized. The Company regularly reviews the deferred tax assets for recoverability considering historical profitability, projected future taxable income, future reversals of existing taxable temporary differences, as well as feasible tax planning strategies in each jurisdiction. As of January 1, 2022, January 2, 2021 and December 30, 2017,28, 2019, the Company recordedhad a valuation allowance of $0.8$13.1 million, $7.6 million and $3.8 million, respectively, for certain foreign deferred tax assets for which the Company believes do not meet the "more likely than not" criteria for recognition.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the "Act") was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a federal corporate tax rate decrease from 35% to 21% for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system and a one-time transition tax on the mandatory deemed repatriation of foreign earnings. We have estimated our provision for income taxes in accordance with the Act and guidance available as of the date of this filing and as a result have recorded a one-time income tax provision of $11.9 million in the fourth quarter of 2017, the period in which the legislation was enacted. The one-time income tax provision includes $8.9 million related to the remeasurement of certain deferred tax assets and liabilities based on the tax rates at which they are expected to reverse in the future. The one-time income tax expense also includes a provisional amount of $3.0 million related to the one-time transition tax on the mandatory deemed repatriation of foreign earnings.
On December 22, 2017, Staff Accounting Bulletin No. 118 (SAB 118) was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. In accordance with SAB 118, we have determined that the $3.0 million of current income tax provision recorded relating to the transition tax on the mandatory deemed repatriation of foreign earnings was a provisional amount and a reasonable estimate at December 30, 2017. Additional information and analysis is necessary to complete the calculation and accounting relating to the transition tax on the mandatory deemed repatriation of foreign earnings. Any subsequent adjustments to this amount will be recorded to current income tax provision during the measurement period which is not expected to extend beyond one year from the enactment date.
Concentration of Credit Risk and Significant Customers
Financial instruments which potentially expose the Company to concentrations of credit risk consist of accounts receivable.receivable and cash and cash equivalents. Management believes its credit policies are prudent and reflect normal industry terms and business risk. At December 30, 2017,January 1, 2022 and January 2, 2021, one customer accounted for a total of 11.5%14.5% and 17.6% , respectively, of the Company's accounts receivable balance. AtFor the fiscal years ended January 1, 2022, January 2, 2021, and December 31, 2016, three customers28, 2019, there was one customer that accounted for a10% or more of total of 43.9%revenue, representing 21.8%, 22.7% and 21.3%, of the Company's accounts receivable balance, each of which was greater than 10% of the balance and two of whom secured their balance with guaranteed letters of credit, which together represents 32.5% of the balance. For the fiscal year ended December 30, 2017, the Company generated 13.5% of total revenue, from one of its retailers (Amazon). For the fiscal year ended December 31, 2016, the Company generated 12.9%, 12.3% and 10.4% of total revenue from its distributor in Japan, Sales On Demand Corporation (SODC), Robopolis SAS, a network of affiliated European distributors (Robopolis) and Amazon, respectively. For the fiscal year ended January 2, 2016, the Company generated 13.3% and 12.7% of total revenue from SODC and Robopolis, respectively. On April 3, 2017, the Company acquired the iRobot-related distribution business of SODC, and on October 2, 2017, the Company acquired Robopolis (see Note 3).
The Company maintains its cash in bank deposit accounts and money market funds at high quality financial institutions. The individual balances, at times, may exceed federally insured limits. These deposits may be redeemed upon demand, and management believes that the financial institutions that hold the Company’s cash and cash equivalents are financially sound and, accordingly, minimal credit risk exists with respect to cash and cash equivalents.

During the fourth quarter of 2017, the Company adopted this standard, which did not have an impact on the Company's consolidated financial statements and related disclosures.
In January 2017, the FASB issued ASU No. 2017-04, "Intangibles - Goodwill and Other." ASU 2017-04 eliminates step 2 from the goodwill impairment test, instead requiring that an entity recognize an impairment charge for the amount by which the carrying amount of goodwill exceeds the reporting unit's fair value. ASU 2017-04 is effective for fiscal years, beginning after December 15, 2019, including interim periods within those fiscal years,2020, with early adoption permitted.

Under the new standard, all excess tax benefits and tax deficiencies are recorded as a component of the provision for income taxes in the reporting period in which they occur. Additionally, ASU 2016-09 requires that the Company present excess tax benefits on the Statement of Cash Flows as an operating activity.retrospective, modified retrospective or prospective basis. The Company adopted ASU 2016-09 effective January 1, 2017the standard in the first quarter of 2021 and elected to apply this adoption prospectively.

The Company adopted ASU 2015-11 effective January 1, 2017. The adoption of this standard did not have a material impact on the Company's consolidated financial statements and related disclosures.
Recently Issued Accounting Standards
In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging," that was created to better align accounting rules with a company’s risk management activities, better reflect the economic results of hedging in the financial statements, and simplify hedge accounting treatment. The guidance is effective forthose fiscal years, beginning after December 15, 2018, including interim periods within those fiscal years,2022, with early adoption permitted. For cash flow hedges existing atThe Company intends to adopt the

ASU effective January 1, 2023, and does not expect a material impact to its consolidated financial statements.

adoption date, the standard requires adoption on a modified retrospective basis with a cumulative-effect adjustment to the consolidated balance sheet as of the beginning of the year of adoption. The amendments to presentation guidance and disclosure requirements are required to be adopted prospectively. The Company is currently evaluating the impact of the standard on its consolidated financial statements.
In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory." ASU 2016-16 clarifies the accounting for the current and deferred income taxes for an intra-entity transfer of an asset other than inventory. ASU 2016-16 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. The Company does not believe the adoption of ASU 2016-16 will have a material impact on its consolidated financial statements.
In February 2016, the FASB issued ASU No. 2016-02, "Leases." ASU 2016-02 requires lessees to recognize the assets and liabilities on their balance sheet for the rights and obligations created by most leases and continue to recognize expenses on their income statements over the lease term. It will also require disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. The guidance is effective for annual reporting periods beginning after December 15, 2018 and interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of the pending adoption of ASU 2016-02 on its consolidated financial statements, and currently expects that most of its operating lease commitments will be subject to the new standard and recognized as operating lease liabilities and right-of-use assets upon its adoption of ASU 2016-02, which will increase the total assets and total liabilities that the Company reports relative to such amounts prior to adoption.
In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers," which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The new guidance was originally effective for annual reporting periods beginning after December 15, 2016, including interim periods within those annual reporting periods. In July 2015, the FASB voted to defer the effective date of the new accounting guidance related to revenue recognition by one year to December 17, 2017 for annual reporting periods beginning after that date and permitted early adoption of the standard, but not before the original effective date of December 15, 2016. The standard will be effective for the Company beginning in the first quarter of 2018. The Company will adopt the standard using the modified retrospective method.
The Company primarily derives its revenue from product sales. The adoption is not expected to have a material effect on the timing of recognition or measurement of revenue from the Company’s product sales. The Company also derives revenue from sales of connected robots, which represent arrangements with multiple performance obligations consisting of the robot, the iRobot Home app, potential future unspecified software upgrades and cloud services. ASU 2014-09 requires revenue to be allocated amongst material performance obligations based on stand-alone selling price and recognized based on the transfer of control of the material performance obligations. It is the Company’s position that the app, upgrades and cloud services related to the current offerings constitute a single immaterial performance obligation and therefore, the revenue associated with the robot and services will be recognized upon transfer of control to the customer.
The Company's product sales are typically subject to limited rights of return, rebates, discounts and promotions and price protection. Accordingly, the Company reduces revenue for its estimates of allowances for these rights of return, rebates, discounts and promotions and price protection at the time the related sale is recorded based on contractual term, future expectation and historical experience. The Company does not expect that there will be material changes to the recognition of these allowances, and that these will continue to be recorded at the time the related revenue is recorded for the sales. The Company does expect that upon adoption of the standard, certain compliance-related charges will be estimated and recorded as a reduction of revenue at the time of sale, rather than upon resolution of the validity of the charges, but expects the impact of this to be immaterial to revenue.
The Company does not expect the provisions of the new standard to impact the manner in which it treats certain costs to fulfill contracts (i.e., shipping and handling costs) and costs to acquire new contracts (i.e., commissions). Under the new standard, the Company will elect the practical expedient on shipping and handling costs and continue to treat these costs as fulfillment costs and expense as incurred. Further, commissions will continue to be expensed as incurred as the impact to the consolidated financial statements is immaterial. The new standard will also result in enhanced revenue related disclosures.
From time to time, new accounting pronouncements are issued by FASB that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption.

3.Business CombinationsRevenue Recognition
AcquisitionThe Company primarily derives its revenue from the sale of Robopolis
On October 2, 2017,consumer robots and accessories. The Company sells products directly to consumers through online stores and indirectly through resellers and distributors. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company closedexpects to receive in exchange for those products or services. Revenue is allocated to distinct performance obligations and is recognized net of allowances for returns and other credits and incentives. Revenue is recognized only to the acquisitionextent that it is probable that a significant reversal of revenue will not occur and when collection is considered probable. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from revenue. Shipping and handling expenses are considered fulfillment activities and are expensed as incurred.
Frequently, the Company’s contracts with customers contain multiple promised goods or services. Such contracts may include any of the following, the consumer robot, downloadable app, cloud services, accessories on demand, potential future unspecified software upgrades, premium customer care and extended warranties. For these contracts, the Company accounts for the promises separately as individual performance obligations if they are distinct. Performance obligations are considered distinct if they are both capable of being distinct and distinct within the context of the contract. In determining whether performance obligations meet the criteria for being distinct, the Company considers a number of factors, such as the degree of interrelation and interdependence between obligations, and whether or not the good or service significantly modifies or transforms another good or service in the contract. The Company’s consumer robots are highly dependent on, and interrelated with, the embedded software and cannot function without the software. As such, the consumer robots are accounted for as a single performance obligation. The Company has determined that the app, cloud services and potential future unspecified software upgrades represent one performance obligation to the customer to enhance the functionality and interaction with the robot (referred to collectively as "Cloud Services"). Other services and support are considered distinct and therefore are treated as separate performance obligations.
The Company allocates revenue to all distinct performance obligations based on their relative stand-alone selling prices ("SSPs"). When available, the Company uses observable prices to determine SSPs. When observable prices are not available, SSPs are established that reflect the Company’s best estimates of what the selling prices of the performance obligations would be if they were sold regularly on a stand-alone basis. The Company’s process for estimating SSPs without observable prices considers multiple factors that may vary depending upon the facts and circumstances related to each performance obligation including, market data or the estimated cost of providing the products or services. The transaction price allocated to the robot is recognized as revenue at a point in time when control is transferred, generally as title and risk of loss pass, and when collection is considered probable. The transaction price allocated to the Cloud Services is deferred and recognized on a straight-line basis over the estimated term of the Cloud Services. Other services and support are recognized over their service periods. For contracts with a duration of greater than one year, the transaction price allocated to performance obligations that are unsatisfied as of January 1, 2022 and January 2, 2021 was $20.9 million and $11.5 million, respectively. The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less.
The Company’s products generally carry a one-year or two-year limited warranty that promises customers that delivered products are as specified. The Company does not consider these assurance-type warranties as a separate performance obligation and therefore, the Company accounts for such warranties under ASC 460, "Guarantees." For contracts with the right to upgrade to a new product after a specified period of time, the Company accounts for this trade-in right as a guarantee obligation under ASC 460. The total transaction price is reduced by the full amount of the trade-in right's fair value and the remaining transaction price is allocated between the performance obligations within the contract.

The Company provides limited rights of returns for direct-to-consumer sales generated through its online stores and certain resellers and distributors. The Company records an allowance for product returns based on specific terms and conditions included in the customer agreements or based on historical experience and the Company's expectation of future returns. In addition, the Company may provide other credits or incentives which are accounted for as variable consideration when estimating the amount of revenue to recognize. Where appropriate, these estimates take into consideration relevant factors such as the Company’s historical experience, current contractual requirements, specific known market events and forecasted inventory level in the channels. Overall, these reserves reflect the Company’s best estimates, and the actual amounts of consideration ultimately received may differ from the Company’s estimates. Returns and credits are estimated at the time of sale and updated at the end of each reporting period as additional information becomes available. As of January 1, 2022, the Company has reserves for product returns of $56.8 million and other credits and incentives of $101.6 million. As of January 2, 2021, the Company had reserves for product returns of $64.3 million and other credits and incentives of $142.2 million. The Company regularly evaluates the adequacy of its largest European distributor, Robopolis SAS, a French company (Robopolis), subsequently renamed to iRobot France SAS. The initial purchase price was approximately $170.1 million in cash, net of acquired cash of $38.0 million, subject to the finalization of the working capital adjustment in accordance with the stock purchase agreement. The acquisition will better enableestimates for product returns and other credits and incentives. Future market conditions and product transitions may require the Company to maintain its leadership positiontake action to change such programs and grow its business in several Western European countries through direct control of pre- and post-sales market activities including sales, marketing, branding, channel relationships and customer service. The results of operations for this acquisition have been included inrelated estimates. When the Company’s operating results since the acquisition date.
The estimated fair values of assets acquired and liabilities assumed are provisional and are based on the information that was available as of the acquisition datevariables used to estimate these reserves change, or if actual results differ significantly from the fair value of assets acquired and liabilities assumed. Therefore, the provisional measurements of fair value reflected are subject to change and such changes could be significant. The Company is continuing to analyze certain pre-acquisition income tax filing positions of Robopolis in various taxing jurisdictions that will assistestimates, the Company would be required to increase or reduce revenue to reflect the impact. During fiscal 2021 and 2020, changes to these estimates related to performance obligations satisfied in finalizing the amounts to record any assumed uncertain income tax positions. The Company expects to finalize the valuation and complete the purchase price allocation as soon as practicable, but no later than one year from the acquisition date.prior periods were not material.

Unbilled receivables8,747 — 
Contract liabilities22,996 17,700 
The Company invoices customers based upon contractual billing schedules, and accounts receivable are recorded when the fairright to consideration becomes unconditional. Unbilled receivables represent revenue recognized in excess of billings. Contract liabilities include deferred revenue associated with the Cloud Services and extended warranty plans as well as prepayments received from customers in advance of product shipments. The change in the opening and closing balances of the Company’s contract assets and contract liabilities primarily results from the timing difference between the Company’s performance and the customer’s payment. During fiscal 2021and 2020, the Company recognized $12.5 million and $5.5 million, respectively, of the contract liability balance as revenue upon transfer of the products or services to customers.
4.Leases
The Company's leasing arrangements primarily consist of operating leases for its facilities which include corporate, sales and marketing and research and development offices and equipment under various non-cancelable lease arrangements. For leases with terms greater than 12 months, the Company records the related right-of-use asset and lease obligation at the present value of lease payments over the acquired identifiable intangible assets and related estimatesterm. Leases with an initial term of useful lives:
  Useful Life Fair Value

The amount assigned to identifiable intangible assets acquired was based12 months or less are not recorded on their fair values determined as of the acquisition date, primarily using the income approach by discounting to present value the free cash flows expected to be generated by each asset over its remaining life. The discount rate used was approximately 14.5%. Reacquired distribution rights are amortized on an accelerated basis while all other intangible assets are amortized over their respective estimated useful livesbalance sheet. Lease expense is recognized on a straight-line basis consistent with the pattern in which the economic benefits are being utilized.

Goodwill represents the excess of the purchase price over the fair valueslease term. The Company's leases typically include rental escalation clauses, renewal options and/or termination options that are factored into the determination of lease payments when appropriate. The Company does not separate lease and non-lease components of contracts and excludes all variable lease

Acquisition of Sales On Demand Corporation
On April 3, 2017,The Company's existing leases do not provide a readily determinable implicit rate. Therefore, the Company closedestimates its acquisition ofincremental borrowing rate to discount the iRobot-related distribution business of Sales On Demand Corporation (SODC), iRobot Japan G.K., for approximately $16.6 million in cash, equal to the book value of the acquired assets.  The acquisition will better enable the Company to maintain its leadership position and accelerate the growth of its business in Japan through direct control of pre- and post-sales market activities including sales, marketing, branding, channel relationships and customer service. It also expandslease payments. At January 1, 2022, the Company's presence and customer outreach opportunities in Japan. The acquisitionweighted average discount rate was a stock purchase. The results of operations for this acquisition have been included in3.58%, while the Company's operating results since the acquisition date.
During the three months ended September 30, 2017, the Company finalized the purchase price allocation and made measurement period adjustments to the provisional amounts reported as the estimated fair values of assets acquired. These measurement period adjustments resulted in a $2.2 million non-taxable gain on business acquisition which represents the excess of the fair value of the net assets acquired over the purchase price. The gain on business acquisitionweighted average remaining lease term was recorded within other income, net in the consolidated statements of income. The Company believes that the gain on business acquisition was due to the transaction not being subjected to a competitive bidding process and the purchase price being determined based on the net book value of the net assets acquired.7.61 years.

4.5.Divestiture
In April 2016, the Company completed the sale of its defense and security business unit to iRobot Defense Holdings, Inc., a portfolio company of Arlington Capital Partners. The final purchase price, including adjustments for working capital and indebtedness, was $24.5 million. The Company recognized a gain of $0.4 million on the sale of assets. The sale of its defense and security business did not meet the criteria for discontinued operations presentation as it did not represent a strategic shift that had a major effect on the Company's operations and financial results.
The Company and iRobot Defense Holdings, Inc. also entered into a Transition Services Agreement (TSA), pursuant to which the Company continued to perform certain functions on iRobot Defense Holdings Inc.’s behalf during a transition period not to exceed 12 months. The TSA provided for the reimbursement to the Company for direct costs incurred in order to provide such functions and was recorded as a component of other income. The transition period was completed during the three months ended April 1, 2017.

On November 15, 2021, the Company closed its acquisition of Aeris Cleantec AG ("Aeris"), a fast-growing provider of premium air purifiers, for approximately $71.4 million in cash. The acquisition will advance the Company's vision and strategy by enabling it to diversify its product offerings and grow new and existing consumer relationships with enhanced solutions that complement the core products. The purchase price was allocated based on estimated fair value of acquired intangible assets of $21.0 million, including $15.5 million of developed technology and $5.5 million of customer relationships, with a weighted estimated useful life of 5 years, net tangible assets of $10.1 million and goodwill of $52.7 million, The acquisition was a stock purchase and the goodwill resulting from this acquisition is not deductible for tax purposes. Goodwill is primarily attributed to the value expected from synergies resulting from the combination. The fair values assigned to tangible and intangible assets acquired and liabilities assumed are based on management’s estimates and assumptions and may be subject to change as additional information is received. The Company expects to finalize the fair value measurements as soon as practicable, but not later than one year from the acquisition date.

Stock-based compensation breaks down by expense classification as follows (in thousands):
The risk-free interest rate is derived from the average U.S. Treasury constant maturity rate, which approximates the rate in effect at the time of grant, commensurate with the expected life of the instrument. The dividend yield is zero based upon the fact the Company has never paid and has no present intention to pay cash dividends. The Company utilizes company specific historical data for purposes of establishing expected volatility and expected term.

14.13.Commitments and Contingencies
Legal Proceedings
From time to time and in the ordinary course of business, the Company is subject to various claims, charges and litigation. The outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to us, which could materially affect our financial condition or results of operations.
Lease Obligations
The Company leases its facilities. Rental expense under operating leases for fiscal years 2017, 2016 and 2015 amounted to $8.9 million, $6.0 million, and $4.9 million, respectively. Future minimum rental payments under operating leases were as follows as of December 30, 2017:

20206,506
20216,502
20226,498
Thereafter39,839
Total minimum lease payments$72,607
Outstanding Purchase Orders
At December 30, 2017,January 1, 2022, we had outstanding purchase orders aggregating approximately $74.4$363.9 million. The purchase orders, the majority of which are with our contract manufacturers for the purchase of inventory in the normal course of business, are for manufacturing and non-manufacturing related goods and services, and are generally cancelablecancellable without penalty.  In circumstances where we determine that we have financial exposure associated with any of these commitments, we record a liability in the period in which that exposure is identified.
Guarantees and Indemnification Obligations
The Company enters into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, the Company indemnifies and agrees to reimburse the indemnified party for losses incurred by the indemnified party, generally the Company’s customers, in connection with any patent, copyright, trade secret or other proprietary right infringement claim by any third party. The term of these indemnification agreements is generally perpetual any time after execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal. Accordingly, the Company has no liabilities recorded for these agreements as of December 30, 2017January 1, 2022 and December 31, 2016,January 2, 2021, respectively.
Government Contract Contingencies
Prior to the completion of the divestiture of our defense and security business unit during the second quarter of 2016, the Company had several prime contracts with the U.S. federal government which did not contain a limitation of liability provision, creating a risk of responsibility for direct and consequential damages. Several subcontracts with prime contractors hold the prime contractor harmless against liability that stems from our work and do not contain a limitation of liability. These provisions could cause substantial liability for the Company. In addition, the Company is subject to audits by the U.S. federal government as part of routine audits of government contracts. As part of an audit, these agencies may review the Company’s performance on contracts, cost structures and compliance with applicable laws, regulations and standards. If any of its costs are found to be allocated improperly to a specific contract, the costs may not be reimbursed and any costs already reimbursed for such contract may have to be refunded. Accordingly, an audit could result in a material adjustment to our revenue and results of operations. Annually, the Company submitted final indirect billing rates to DCMA based upon actual costs incurred throughout the year. These final billing rates are subject to audit by DCAA. As of December 30, 2017, fiscal year 2016 is open for audit by DCAA.

Due to the adoption of ASU 2016-09 in 2017, all excess tax benefits and deficiencies are recognized as income tax expense in the Company’s consolidated statement of income. This will result in increased volatility in the Company’s effective tax rate.
On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the "Act") was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a federal corporate tax rate decrease from 35% to 21% for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system and a one-time transition tax on the mandatory deemed repatriation of foreign earnings. The Company has estimated the(benefit) provision for income taxes in accordance with the Act and guidance available as of the date of this filing and as a result have recorded a one-time income tax provision of $11.9 million as additional income tax provision in the fourth quarter of 2017, the period in which the legislation was enacted. The one-time income tax provision includes $8.9 million related to the remeasurement of certain deferred tax assets and liabilities based on the tax rates at which they are expected to reverse in the future. The one-time income tax expense also includes a provisional amount of $3.0 million related to the one-time transition tax on the mandatory deemed repatriation of foreign earnings.
On December 22, 2017, Staff Accounting Bulletin No. 118 (SAB 118) was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. In accordance with SAB 118, the Company has determined that the $3.0 million of current income tax provision recorded relating to the transition tax on the mandatory deemed repatriation of foreign earnings was a provisional amount and a reasonable estimate at December 30, 2017. Additional information and analysis is necessary to complete the calculation and accounting relating to the transition tax on the mandatory deemed repatriation of foreign earnings. Any subsequent adjustments to this amount will be recorded to current income tax provision during the measurement period which is not expected to extend beyond one year from the enactment date.

The Company accrues interest and, if applicable, penalties for any uncertain tax positions as a component of income tax expense. As of December 30, 2017, December 31, 2016 andJanuary 1, 2022, January 2, 20162021 and December 28, 2019 there were no material accrued interest or penalties. The Company does not expect a significant change in the amount of unrecognized tax benefits within the next 12 months. If all of the Company's unrecognized tax benefits as of January 1, 2022 were to become recognizable in the future, it would record a $11.2 million benefit, inclusive of interest, to the income tax provision.
The Company is subject to taxation in the United States (federal and state) and foreign jurisdictions. The statute of limitations for examinations by the Internal Revenue Service (the "IRS") is closed for fiscal years prior to 2014. The statute of limitations for examinations byand state tax authorities is closed for fiscal years prior to 2013.2014 and fiscal 2016. Federal and state carryforward attributes that were generated prior to fiscal 2014 and 2013, respectively,during fiscal 2016 may still be adjusted upon examination by the federal or state tax authorities if they either have been or will be used in a period for which the statute of limitations is still open. The Company is currently under examination by the IRS for the years 2014 and 2015. The IRS notified the Company doesduring the fourth quarter of fiscal 2020 that it intends to disallow the Company’s deductions related to domestic production activities for those tax years. We currently believe the ultimate disposition of this matter will not expecthave a significant changematerial adverse effect on our consolidated financial position, liquidity or results of operations. There are other ongoing audits in various other jurisdictions that are not material to the Company's financial statements.  The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes. The Company continues to monitor the progress of ongoing discussions with tax authorities and the effect, if any, of the expected expiration of the statute of limitations in various taxing jurisdictions.  The Company believes that an adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the amountCompany's tax audits are resolved in a manner not consistent with management's expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. Although the timing of unrecognizedresolution, settlement, and closure of audits is not certain, it is reasonably possible that certain U.S. federal and non-U.S. tax benefitsaudits may be concluded within the next 12 months. If allmonths, which could increase or decrease the balance of the Company's gross unrecognized tax benefits as of December 30, 2017 were to become recognizable in the future, it would record a $2.0 million benefit, inclusive of interest, to the income tax provision.benefits.

ITEM 9A.    CONTROLS AND PROCEDURES
Evaluation of disclosure controls and procedures.
As required by Rule 13a-15(b) under the Exchange Act, we have carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer (CEO)("CEO") and our Chief Financial Officer (CFO)("CFO"), of the effectiveness, as of the end of the period covered by this report, of the design and operation of our "disclosure controls and procedures" as defined in Rule 13a-15(e) promulgated by the SEC under the Exchange Act. Based upon that evaluation, our CEO and our CFO concluded that our disclosure controls and procedures, as of the end of such period, were adequate and effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information was accumulated and communicated to management, as appropriate, to allow timely decisions regarding required disclosure.
Management’s Report on Internal Control Over Financial Reporting
The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers and effected by the Company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:
Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;
Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with 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
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.
Under the supervision and with the participation of management, including our principal executive and financial officers, we assessed the Company’s internal control over financial reporting as of December 30, 2017,January 1, 2022, based on criteria for effective internal control over financial reporting established in Internal Control — Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Based on this assessment, management concluded that the Company maintained effective internal control over financial reporting as of December 30, 2017January 1, 2022 based on the specified criteria.
The effectiveness of the Company’s internal control over financial reporting as of December 30, 2017January 1, 2022 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included herein.
