Overview

iRobot Corporation (“iRobot” or the “Company” or “we”) designs and builds robots that make a difference. For over 20 years, we have developed proprietary technology incorporating advanced concepts in navigation, mobility, manipulation and artificial intelligence to build industry-leading robots. Our home care robots perform time-consuming domestic chores while our defense and security robots perform tasks such as battlefield reconnaissance and bomb disposal, and multi-purpose tasks for local police and first responders. We sell our robots to consumers through a variety of distribution channels, including chain stores and other national retailers, and through our on-line store, and to the U.S. military and other government agencies worldwide. We maintain certifications for AS9100 for certain programs within our defense and security business unit.

Since our founding, we have accumulated expertise in all the disciplines necessary to design and build 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, reducing the time, cost and risk of product development. Our significant expertise in robot design and engineering, combined with our management team's experience in military and consumer markets, positions us to capitalize on the growth we expect in the market for robot-based products. We believe that the sophisticated technologies in our existing consumer and military applications are adaptable to a broad array of markets such as law enforcement, homeland security, commercial cleaning, elder care, energy services, home automation, healthcare, landscaping, agriculture, construction and other vertical markets.

Over the past ten years, we have sold more than eight million of our home care robots. During that time, we also sold more than 4,500 of our tactical military robots, most of which have been sold to the U.S. military and deployed on missions in Afghanistan and Iraq, and more recently to state, local and international government entities.

Our business evolved significantly in fiscal 2012. We are a different company than we were one year ago. Total revenue for 2012 was $436.2 million, which represented a 6% decline from 2011 revenue of $465.5 million. This decrease in revenue was directly attributable to a $107.5 million decrease in revenue in our defense and security business related to troop withdrawals in Afghanistan, program cancellations and ongoing budget reductions within the U.S. government. Revenue in our home robots business increased by $78.2 million in 2012 compared to 2011 as a direct result of growth in both domestic and international markets. This increase in home robots business revenue was driven by demand for our new Roomba 700 series robot, the introduction of the Roomba 600 series robot and an increase in marketing programs by us and our international distributors. Our home robots revenue represented 82% of our total 2012 revenue compared to 60% in 2011. We anticipate that our revenue for the next few years will be primarily driven by our rapidly growing home technology business and that our home robots revenue will comprise approximately 90% of our total revenue in the near term.

In response to the changing nature of our business, we took a number of actions in fiscal 2012 which we believe will assist us in returning to growth in 2013 and beyond. In particular:

• We undertook a company-wide restructuring designed to provide us greater overall flexibility, improved efficiency and scalability as a more unified organization. In conjunction with this restructuring, we created centralized, shared services such as engineering, operations and finance to promote further the use of common platforms and ensure repeatable successes through improved collaboration and standardization while focusing engineering efforts on markets with the greatest visibility and revenue potential. We expect this new structure to be fully operational in 2013.

3

• We initiated significant cost reductions in our defense and security business to realign our cost structure with our reduced revenue expectations for this business.

• We restructured our maritime business, which operated in North Carolina as part of our defense and security business. Although we believe that there is a future for unmanned underwater vehicles, the product market has not materialized as quickly as we expected. As a result, we have closed our North Carolina office, shut down our maritime product business and relocated our maritime research to our headquarters in Bedford, Massachusetts as a way to efficiently continue to pursue this business in a cost-effective manner.

• We wrote-off certain non-performing assets and inventory to levels that support our reduced revenue outlook for our defense and security business.

• We increased our investment in marketing programs in our home robots business, which resulted in greater brand awareness and revenue growth in that business. We expect to continue investing in marketing programs in 2013.

• Together with InTouch Health, we jointly introduced the RP-VITA, the first autonomous navigation remote presence robot to receive U.S. Food and Drug Administration clearance for use in hospitals. The RP-VITA, which will begin shipping in early 2013, combines the latest in autonomous navigation and mobility technologies developed by iRobot with the state-of-the-art telemedicine and electronic health record integration developed by InTouch Health.

• In October 2012, we acquired Evolution Robotics, Inc., developer of the Mint and Mint Plus automatic floor cleaning robots. This acquisition expands our technology leadership through a combination of intellectual property, engineering talent and new products that will broaden our global portfolio of practical robotics solutions.

Strategy

Our goal is to design and market innovative robots that make a difference and are adaptable for use in a broad range of applications. We strive to drive innovation, serve as an industry catalyst and change the world by fueling the era of robots. We intend to increase the penetration of our products in existing markets, expand existing products into new markets, and develop and launch new products into current and adjacent markets. Our strategy is to maintain a leadership position by delivering robotic technology-based remote presence and automated home maintenance solutions that delight our customers and anticipate their needs, while extending our technical leadership in the areas of robot autonomy, manipulation and platforms. Remote presence is the core of our military robots which save lives by keeping warfighters and public safety workers at safe standoff distances from hazards while they perform dangerous, difficult and persistent missions. With increasing levels of autonomy, continued mobility improvements, more sophisticated sensor suites and advanced human interfaces, remote presence systems will expand in effectiveness and efficiency and reduce the requirements for actual physical operator presence and control. In the area of automated home maintenance, we seek to improve the quality of life with robotic solutions requiring as little human physical intervention as possible. Key elements of our strategy include:

Leverage Common Platforms and Software.    By committing long-term to a given platform and providing incremental upgrades, we create a valuable installed base that supports third-party development and greatly simplifies service and support. When entering new product areas that cannot be serviced with existing platforms, we intend to develop a multi-generational platform strategy that allows for rapid learning and long-term incremental improvements. Through the use and development of a common software architecture, we intend to create a robot intelligence system of enduring value and build a formidable advantage that stifles competition. Our common software will allow high reuse, reducing development costs of new systems and payloads, as well as reducing development timelines.

Continued Growth through Profitability, Operational Excellence and Customer Focus.    We intend to consistently improve our profitability through disciplined allocation of resources and by reducing costs of materials, adjusting prices, optimizing our product and channel mix and focusing on our discretionary spending. We will continue to focus on improving the scalability and efficiency of our supply chain process and on mitigating single source supply exposure. We will identify, develop and enhance product features and functionality while also aggressively focusing on product reliability.

Leverage Research and Development Across Different Products and Markets.    We leverage our research and development across all of our products and markets. For example, we use technological expertise developed through government-funded research and development projects across our other product development efforts. Similarly, expertise developed while designing consumer products is used in designing products for defense and security applications. This strategy helps us avoid the need to start each robot project from scratch, developing robots in a cost-effective manner and minimizing time to market.

Continue to Strengthen Our Brand.    Our robots' performance and uniqueness have enabled us to obtain strong word-of-mouth and extensive press coverage leading to increasing brand awareness, brand personality and momentum. We intend to increase our investment in our marketing programs to strengthen our brand recognition and reinforce our message of innovation, reliability, safety and value.

4

Complement Core Competencies with Strategic Alliances.    Our core competencies are the design, development and marketing of robots. We rely on strategic alliances to provide complementary competencies that we integrate into our products and to enhance market access. We outsource certain non-core activities, such as manufacturing and back-office functions, which helps us focus our resources on our core competencies.

Technology

We are focused on behavior-based, artificially-intelligent systems developed to meet customer requirements in multiple market segments. In contrast to robotic manufacturing equipment or entertainment systems that are designed to repeat actions in specific, known environments, our systems are designed to complete missions in complex and dynamic real-world environments.

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 efficiently.

AWARE Robot Intelligence Systems.    Our proprietary AWARE Robot Intelligence Systems are code bases that enable the behavioral control of robots. Moreover, the AWARE systems include modules that control behaviors, sensor fusion, power management and communication. Our AWARE systems allow our Roomba floor vacuuming robot and our Scooba floor washing robot to clean an entire floor while navigating around obstacles and not falling down stairs, and also allow our PackBot robots and our other unmanned ground vehicles to accomplish complex missions such as waypoint navigation and real-time obstacle avoidance.

Real-World, Dynamic Sensing.    The degree of intelligence that our robots display is directly attributable to their ability to perceive - or sense - the world around them. Using specialized hardware and signal processing, we have developed sensors that fit particular cost-performance criteria. In other cases, we use off-the-shelf sensing hardware, such as laser scanners, cameras and optical sensors.

User-Friendly Interfaces.    Our robots allow users to interact and instruct our robots in intuitive ways without extensive end-user set-up, installation, training or instruction. For example, our Roomba robots require only one button to have the robot begin its mission, determine the size of the room to be cleaned, thoroughly clean the room and return to its re-charger, right out of the box without any pre-programmed knowledge of the user's home. Similarly, our PackBot robots use intuitive controllers, interoperable between systems, that integrate high-level supervisory commands from the user into the behaviors of the robot.

Tightly-Integrated, Electromechanical Design.    Our products rely on our ability to build inherently robust integrated electrical and mechanical components into required form factors. For instance, the computer that powers the PackBot tactical military robot must withstand being dropped from more than ten feet onto concrete. Such high performance specifications require tight design integration.

Combining these four components, we have created proprietary, reusable building blocks of robotics capabilities, including mobility platforms, manipulators, navigation and control algorithms and user interfaces. Our technology building blocks typically allow us to take a known platform and modify it for a new mission instead of starting from scratch for each application. We believe this allows us to design and develop innovative robots cost-effectively.

Products and Development Contracts

We design and market robots for the consumer and defense and security markets. With two decades of leadership in the robot industry, we remain committed to establishing robot and software platforms for invention and discovery, building key partnerships to develop mission-critical payloads and creating robots that improve the standards of safety and living worldwide.

Consumer Products

We sell various products that are designed for use in and around the home. Our current consumer products are focused on both indoor and outdoor cleaning applications. We believe our consumer products provide value to our customers by delivering better cleaning solutions at an affordable price and by freeing people from repetitive home cleaning tasks.

We currently offer multiple Roomba floor vacuuming robots with varying price points ranging from $349 to $699 based upon performance characteristics. Our Roomba robot's compact disc shape allows it to clean under beds and other furniture, resulting in cleaner floors since the Roomba can access more of the floor than standard upright vacuum cleaners. In addition, Roomba eliminates the need to push a vacuum - it cleans automatically upon the push of a button. The Roomba 700 series robots, introduced in 2011, offers improved debris pick up, a larger debris bin that vigorously pulls debris and hair off brushes into the bin, and dual HEPA air filters that capture dust particles as fine as 0.3 microns. The Roomba 600 series robots, introduced in 2012, offers a three-stage cleaning system which thoroughly vacuums every section of the floor multiple times, as well as AeroVac technology and improved brush design enabling the robot to better handle fibers like hair, pet fur, lint and carpet fuzz.

5

As a result of our acquisition of Evolution Robotics, Inc., we currently offer two Mint automatic floor cleaning robots designed exclusively for hard surface floors with prices ranging from $199 to $329 based upon performance features. These robots provide a different cleaning approach than our Roomba products. The Mint 4200 automatically dusts and damp mops hard surface floors using popular cleaning cloths or our specially designed reusable microfiber cloths. In addition to these features, the Mint 5200 includes a special reservoir that dispenses liquid throughout the cleaning cycle to keep the cloth damp.

We currently offer several Scooba floor washing robots with price points ranging from $279 to $499. Our Scooba 300 robot's innovative cleaning process allows the robot to simultaneously sweep, wash, scrub and dry hard floors, all at the touch of a button. Unlike a conventional mop that spreads dirty water on the floor, Scooba will apply only fresh water and cleaning solution to the floor from a clean tank. Scooba will clean dirt and grime, is safe for use on all sealed, hard floor surfaces, including wood and tile, and is smart enough to avoid carpet. The Scooba 230, introduced in 2011, is sleek, compact and perfectly sized for hard-to-reach areas like behind bathroom sinks and toilets.

Our Verro Pool Cleaning Robot is used to clean a residential pool and removes debris as small as two microns from the pool floor, walls and stairs. Verro is brought to market under the iRobot brand through a relationship with Aquatron, Inc., which developed the pool cleaning robots. There are two models available.

Our Looj Gutter Cleaning Robot was designed to simplify the difficult and dangerous job of gutter cleaning. The Looj cleans an entire stretch of gutter, reducing the number of times a ladder must be repositioned and climbed during gutter cleaning. The Looj also features a detachable handle that doubles as a wireless remote control, providing full control of the robot while cleaning. The Looj is currently available in North America and will be available in select countries worldwide in Spring 2013.

Defense and Security Products

In defense and security product markets, we currently offer several ground unmanned vehicles. Our tactical ground robots include the combat-tested 510 PackBot line of small, unmanned ground robots, the 310 SUGV and XM1216 SUGV (Small Unmanned Ground Vehicle) multi-purpose ground robots, the 110 FirstLook small, light, throwable robot, and the 710 Warrior multi-purpose robot capable of carrying heavy payloads. The PackBot, SUGV, FirstLook, and Warrior robots comprise a family of robots using many common platform components and offer our patented flipper technology that enables robots to easily climb stairs, navigate rubble, and penetrate inaccessible areas. These robots are designed to keep war fighters and public safety officials out of harm's way and are designed for high-performance, durability and ease of use while performing search, reconnaissance, mapping, bomb disposal and other dangerous missions. As of December 29, 2012, more than 4,500 robots have been delivered to military and civil defense forces and research communities worldwide. The robots are currently priced between approximately $20,000 and $415,000 per unit, depending on configuration and quantities ordered.

We continue to refine the PackBot product line, focusing on enhanced modularity and providing new capabilities to support a variety of mission scenarios. Our unique Aware 2 software is incorporated into the advanced 510 PackBot chassis and operator control unit. As a result, PackBot can support multiple configurations and payloads with the same chassis and operator control unit, providing customers with a single robot capable of performing a variety of missions. We also utilize Configure-To-Order (CTO) procurement options for our commercial 510 PackBot, allowing customers to tailor the product to their specific mission needs. The combined benefits of the Aware 2 software and CTO procurement options establish the 510 PackBot as a truly modular multi-mission robotic platform.

The 310 and XM1216 SUGVs are a family of lightweight, backpackable robots well suited to dismounted operations in Afghanistan. The SUGV has a modular design that accommodates a wide range of optional payloads and sensors, including a dexterous manipulator, and can easily climb stairs, roll over obstacles and enter inaccessible and dangerous areas.

Contract Research and Development Projects

We are involved in contract development projects with various U.S. governmental agencies and departments. The durations of these projects range from a few months to several years. These projects are usually funded as either cost-plus, firm fixed price, or time and materials contracts. In a cost-plus contract, we are allowed to recover our actual costs plus a fixed fee. The total price of a cost-plus contract is based primarily on allowable costs incurred, but generally is subject to a maximum contract funding limit. Under a firm fixed price contract, we receive a fixed amount upon satisfying contractually defined deliverables. On our time and materials contracts, we recover a specific amount per hour worked based on a bill rate schedule, plus the cost of direct materials, subcontracts, and other non-labor costs, including an agreed-upon mark-up. A time and materials contract may provide for a not-to-exceed price ceiling, as well as the potential that we will absorb any cost overrun.

6

Strategic Alliances

Strategic alliances are an important part of our product development and distribution strategies. We rely on strategic alliances to provide technology, complementary product offerings and increased and quicker access to markets. We seek to form relationships with organizations that can provide best-in-class technology or market advantages for establishing iRobot technology in new market segments. For example, in 2011 we signed a joint development and licensing agreement with InTouch Health, a leading remote presence telemedicine solution provider, to explore potential opportunities for healthcare applications on iRobot platforms such as the iRobot Ava mobile robotics platform. This alliance has resulted in the introduction in 2012 of the RP-VITA, the first autonomous navigation remote presence robot to receive U.S. Food and Drug Administration clearance for use in hospitals. The RP-VITA combines the latest in autonomous navigation and mobility technologies developed by iRobot with the state-of-the-art telemedicine and electronic health record integration developed by InTouch Health and we expect will begin shipping in early 2013.

Our strategy of working closely with third parties extends to the design of our products. By offering extensible platforms designed to carry payloads, we have designed and manufactured our products to leverage the work of those individuals and organizations that offer specialized technological expertise. The PackBot, Warrior and FirstLook robots are designed with open interfaces that allow third-party developers to add payloads to our robots, improving their functionality.

Sales and Distribution Channels

We sell our products through distinct sales channels to the consumer and defense and security markets. For the fiscal years ended December 29, 2012, December 31, 2011 and January 1, 2011, sales to non-U.S. customers accounted for 57.3%, 45.5% and 42.1% of total revenue, respectively. For the fiscal years ended December 29, 2012, December 31, 2011 and January 1, 2011, U.S. federal government orders, contracts and subcontracts accounted for 15.1%, 36.1% and 38.4% of total revenue, respectively. For the fiscal years ended December 29, 2012, December 31, 2011 and January 1, 2011, we generated 4.5%, 9.4% and 17.4% of total revenue from The Boeing Company as a subcontractor under U.S. federal government contracts. For the years ended December 29, 2012 and December 31, 2011, we generated an aggregate of 30.6% and 23.6% of our revenue, respectively from our home robots distributor in Japan (Sales on Demand Corporation) and a network of affiliated European distributors of our home robots. 

Home Robots

In the United States and Canada, we sell our consumer products through a network of national retailers. In 2012, this network consisted of more than 30 retailers which often sell either one or some combination of our products. Certain smaller domestic retail operations are supported by distributors to whom we sell our products directly. In support of these sales activities, we maintain an in-house sales and product management team. Outside of the United States and Canada, our products have been sold in more than 40 countries, primarily through a network of in-country distributors who resell to retail stores in their respective countries. These distributors are supported by our international sales and product marketing team.

Our retail and distributor networks are our primary distribution channels for our consumer products. We also offer products direct-to-consumer through our domestic and international on-line stores, representing 6.3% and 9.6% of total home robots business unit revenue for fiscal 2012 and 2011, respectively. We have established valuable databases and customer lists that allow us to target directly those consumers most likely to purchase a new robot or upgrade. We believe we maintain a close connection with our customers in each of our markets, which provides an enhanced position from which to improve our distribution and product offerings.

Defense and Security

We sell our defense and security products directly to end users and indirectly through prime contractors and distributors. While the majority of defense and security products have been sold to date to various operations within the U.S. federal government, we also sell to state and local as well as to international government organizations and research labs and universities. Our military products are sold overseas in compliance with the International Traffic in Arms Regulations, or ITAR. We have sold our products to the governments of various countries in the past several years, including the United Kingdom, France, Germany, Sweden, Norway, Italy, Israel, Australia, Republic of Korea, Singapore, Bosnia, Lithuania, Qatar, Taiwan, South Africa and Canada.

Our government products are sold by a team of sales specialists with significant experience in selling to government and defense agencies. All of these individuals have years of experience selling military products to government procurement offices, both in the United States and internationally. We maintain a direct sales and support presence in Europe.

7

Customer Service and Support

We also provide ongoing customer service and support. Consumer customer service representatives, the majority of whom are employees of outsourced service organizations or our distribution partners, are extensively trained on the technical intricacies of our consumer products. Defense and security customer representatives are usually former military personnel who are experienced in logistical and technical support requirements for military operations.

Marketing and Brand

We market our home robots to end-user customers through our sales and marketing teams as well as through our extensive network of retailers and in-country distributors. We market our defense and security products directly through our team of government sales specialists to end users and indirectly through prime contractors. Our website is also playing an increasing role in supporting brand awareness, addressing customer questions and serving as a showcase for our products.

Our marketing strategy is to increase our brand awareness and associate the iRobot brand with innovation, reliability, safety and value. Our sales and marketing expenses represented 16.4%, 12.6% and 12.6% of our total revenue in 2012, 2011 and 2010, respectively. We expect to continue to invest in national advertising, consumer and industry trade shows, direct marketing and public relations to further build brand awareness.

We believe that we have built a trusted, recognized brand by providing high-quality robots. We believe that customer word-of-mouth has been a significant driver of our brand's success to date, which can work very well for products that inspire a high level of user loyalty because users are likely to share their positive experiences. Our grass-roots marketing efforts focus on feeding this word-of-mouth momentum and we use public relations as well as advertising to promote our products.

Our innovative robots and public relations campaigns have generated extensive press coverage. In addition, iRobot and our consumer robots have won several awards and our inclusion among the first-tier partners on the U.S. Army's Brigade Combat Team Modernization program has greatly enhanced our brand and awareness among defense and security customers. Through these efforts, we have been able to build our brand, and we expect that our reputation for innovative products and customer support will continue to play a significant role in our growth and success.

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 both our consumer and military robots, we can focus our engineering expertise on the design of robots.

Manufacturing a new product requires a close relationship between our product designers and the manufacturing organizations. 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.

We outsource the manufacturing of our consumer products to six contract manufacturers, each of which manufactures at a single plant in China. We outsource the manufacturing of our defense and security robots to three contract manufacturers, all of which are located in the United States.

Research and Development

We believe that our future success depends upon our ability to continue to develop new products and product accessories, and enhancements to and applications for our existing products. For the years ended December 29, 2012, December 31, 2011 and January 1, 2011, our research and development expenses were $37.2 million, $36.5 million and $24.8 million, respectively. In addition to our internal research and development activities, for the years ended December 29, 2012, December 31, 2011 and January 1, 2011, we have incurred research and development expenses under funded development arrangements with defense and security third parties of $16.8 million, $26.5 million and $27.1 million, respectively. Of our total research and development spending in 2012, 2011 and 2010, approximately 29.6%, 40.2% and 50.4%, respectively was funded by government-sponsored research and development contracts. For the years ended December 29, 2012, December 31, 2011 and January 1, 2011, the combined investment in future technologies, classified as cost of revenue and research and development expense, was $54.0 million, $63.0 million and $51.9 million, respectively. We intend to continue our investment in research and development to respond to and anticipate customer needs, and to enable us to introduce new products over the next few years that will continue to address our existing and adjacent market sectors.

Our research and development is conducted by teams dedicated to particular projects. Our domestic research and development efforts are primarily located at our headquarters in Bedford, Massachusetts and our special projects engineering offices in San Luis Obispo and Pasadena, California.

Our research and development efforts for our next-generation products are supported by a variety of sources. Our next-generation defense products are predominately supported by U.S. governmental research organizations. Government funding is provided to further the development of robot technologies with the expectation that if the projects result in the development of technically viable prototypes, the government will purchase multiple production units for future use in the field. The government funding that we receive allows us to accelerate the development of multiple technologies. While the U.S. government retains certain rights to military projects that it has funded, such as the right to use inventions and disclose technical data relating to those projects without constraining the recipient's use of that data, we retain ownership of patents and know-how and are generally free to develop other commercial products, both consumer and industrial, utilizing the technologies developed during these projects. The rights which the government retains, however, may allow it to provide use of patent rights and know-how to others, and some of the know-how might be used by these third parties for their own development of consumer and industrial products. Similarly, expertise developed while designing consumer products is used in designing products for defense and security applications. We also work with strategic collaborators to develop industry-specific technologies.

Competition

The 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. We believe that 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 competitors include developers of robot floor cleaning products, developers of small unmanned ground vehicles and established government contractors working on unmanned systems.

While we believe many of our customers purchase our Roomba floor vacuuming robots, Mint floor cleaning and Scooba floor washing robots as 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.

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, including maintenance and support, ease of use, integration with existing equipment, quality, reliability, customer support, brand and reputation.

Our ability to remain competitive will depend to a great extent upon our ongoing performance in the areas of product development and customer support. We cannot provide assurance 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.

Intellectual Property

We believe that our continued success depends in large part on our proprietary technology, the intellectual skills of our employees 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 of December 29, 2012, we held 164 U.S. patents, 132 foreign patents, additional design registrations, and more than 300 patent applications pending worldwide. Our U.S. patents will begin to expire in 2019. 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. 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, Roomba, Scooba, Mint, ViPR, NorthStar, iRobot Dirt Dog, Create, PackBot, FirstLook, iAdapt, FasTac, Aware, Home Base, Looj, Verro, Virtual Wall, and Warrior. Our marks iRobot, Roomba, Scooba, 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. 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. 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 have been no additional actions or communications with respect to these 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. 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.

Regulations

We are subject to various government regulations, including various U.S. federal government regulations as a contractor and subcontractor to the U.S. federal government. Among the most significant U.S. federal government regulations affecting our business are:

• the Federal Acquisition Regulations and supplemental agency regulations, which comprehensively regulate the formation and administration of, and performance under government contracts;

• the Truth in Negotiations Act, which requires certification and disclosure of all cost and pricing data in connection with contract negotiations;

• the Cost Accounting Standards, which impose accounting requirements that govern our right to reimbursement under cost-based government contracts;

• the Foreign Corrupt Practices Act, which prohibits U.S. companies from providing anything of value to a foreign official to help obtain, retain or direct business, or obtain any unfair advantages;

• the False Claims Act and the False Statements Act, which, respectively, impose penalties for payments made on the basis of false facts provided to the government, and impose penalties on the basis of false statements, even if they do not result in a payment; and

• laws, regulations and executive orders restricting the use and dissemination of information classified for national security purposes and the exportation of certain products and technical data.

We also need special security clearances to continue working on and advancing certain of our projects with the U.S. federal government. Classified programs generally will require that we comply with various Executive Orders, federal laws and regulations and customer security requirements that may include restrictions on how we develop, store, protect and share information, and may require our employees to obtain government clearances.

The nature of the work we do for the federal government may also limit the parties who may invest in or acquire us. Export laws may keep us from providing potential foreign acquirers with a review of the technical data they would be acquiring. In addition, there are special requirements for foreign parties who wish to buy or acquire control or influence over companies that control technology or produce goods in the security interests of the United States. There may need to be a review under the Exon-Florio provisions of the Defense Production Act. Finally, the government may require a prospective foreign owner to establish intermediaries to actually run that part of the company that does classified work, and establishing a subsidiary and its separate operation may make such an acquisition less appealing to such potential acquirers.

10

In addition, the export from the United States of many of our products may require the issuance of a license by the U.S. Department of Commerce under the Export Administration Act, as amended, and its implementing Regulations as kept in force by the International Emergency Economic Powers Act of 1977, as amended. Some of our products may require the issuance of a license by the U.S. Department of State under the Arms Export Control Act and its implementing Regulations, which licenses are generally harder to obtain and take longer to obtain than do Export Administration Act licenses.

Our business may require the compliance with state or local laws designed to limit the uses of personal user information gathered online or require online services to establish privacy policies.

Defense and Security Product Backlog

Our defense and security product backlog consists of written orders or contracts to purchase our products received from our defense and security customers. Total backlog of product sales to defense and security customers, which includes federal, state, local and foreign governments, and non-government customers, as of December 29, 2012 and December 31, 2011 amounted to approximately $11.4 million and $7.6 million, respectively. Our funded research and development contracts may be cancelled or delayed at any time without significant, if any, penalty. As a result, we believe that backlog with respect to our funded research and development is not meaningful. There can be no assurance that any of our backlog will result in revenue.

Employees

As of December 29, 2012, we had 534 full-time employees located in the United States and abroad, of whom 234 are in research and development, 94 are in operations, 82 are in sales and marketing and 124 are in general and administration. We believe that we have a good relationship with our employees.

Available Information

We were incorporated in California in August 1990 under the name IS Robotics, Inc. and reincorporated as IS Robotics Corporation in Massachusetts in June 1994. We reincorporated in Delaware as iRobot Corporation in December 2000. We conduct operations and maintain a number of subsidiaries in the United States and abroad, including operations in Hong Kong, the United Kingdom and China. We also maintain iRobot Securities Corporation, a Massachusetts securities corporation, to invest our cash balances on a short-term basis. Our website address is www.irobot.com. Our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 are available free of charge through the investor relations page of our internet website as soon as reasonably practicable after we electronically file such material with, or furnish it to, the Securities and Exchange Commission.

ITEM 1A.     RISK FACTORS

We operate in a rapidly changing environment that involves a number of risks, some of which are beyond our control. This discussion highlights some of the risks which may affect future operating results. These are the risks and uncertainties we believe are most important for you to consider. 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

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 consumer robots will increase, if at all. Moreover, there are only a limited number of programs under which the U.S. federal government is currently funding the development or purchase of defense robots. 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 and defense markets;

• attract and retain customers of our consumer robots;

• develop and renew government contracts for our defense and security robots;

• attract and retain additional engineers and other highly-qualified personnel;

• expand our product offerings beyond our existing robots; and

• adapt to new or changing policies and spending priorities of governments and government agencies.

11

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.

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 and timing of orders from military and other government agencies;

• the size, timing and mix of orders from retail stores and international distributors for our home care robots;

• the mix of products that we sell in the period;

• disruption of supply of our products from our manufacturers;

• seasonality in the sales of our military and consumer products;

• the inability to attract and retain qualified, revenue-generating personnel;

• unanticipated costs incurred in the introduction of new products;

• costs 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;

• warranty costs associated with our consumer products;

• the amount of government funding and the political, budgetary and purchasing constraints of our government agency customers; and

• cancellations, delays or contract amendments by government agency customers.

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 and, therefore, we would not be able to reduce our operating expenses for the fiscal year. 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.

Global economic conditions and any associated impact on consumer spending could have a material adverse effect on our business, results of operations and financial condition.

Continued economic uncertainty and reductions in consumer spending, particularly in certain international markets such as the European Union, may result in reductions in sales of our consumer robots. Additionally, disruptions in credit markets may materially limit consumer credit availability and restrict credit availability 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 business, results of operations and financial condition.

12

A significant portion of our business currently depends 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 29, 2012 and December 31, 2011, we derived 81.8% and 59.8% of our total revenue from our consumer robots, respectively. For the foreseeable future, we expect that a significant portion of our revenue will be derived from sales of consumer robots in general and home floor care products in particular. Accordingly, our future success depends upon our ability to further penetrate the consumer home care market, to enhance our current consumer products and develop and introduce new consumer products offering enhanced performance and functionality at competitive prices. The development and application of new technologies involve 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 depend on the U.S. federal government for a significant portion of our revenue, and any unexpected reduction in the amount of business that we do with the U.S. federal government would negatively impact our operating results and financial condition.

For the years ended December 29, 2012 and December 31, 2011, we derived 15.1% and 36.1% of our total revenue, respectively, directly or indirectly, from the U.S. federal government and its agencies. Reduction in the amount of revenue that we derive from a limited number of U.S. federal government agencies without an offsetting increase in new sales to other customers would have a material adverse effect on our operating results. U.S. Government programs in which we participate, or in which we may seek to participate in the future, must compete with other programs for consideration during our nation’s budget formulation and appropriation processes, and are and will continue to be affected by changes in general economic conditions or the status of international conflicts. Budget decisions made in this environment may have long-term consequences for our size and structure and that of the defense industry. It is possible that one or more of our programs will be reduced, extended, or terminated. Reductions in our existing programs, unless offset by other programs and opportunities, could adversely affect our ability to grow our sales and profitability.

Specifically, the defense industry in which we operate is dependent upon the level of equipment expenditures by the armed forces of countries throughout the world, and especially those of the United States, which represents a significant portion of world-wide defense expenditures. In prior years, the war on terror increased the level of equipment expenditures by the U.S. armed forces; however, this level of spending does not appear to be sustainable in light of government spending priorities by the U.S. and the continued winding down of U.S. armed forces operations in Iraq and Afghanistan. In addition, as a result of the failure of the Joint Select Committee on Deficit Reduction (Super Committee) to agree on a deficit reduction plan, mandatory reductions in defense may be required under the Budget Control Act of 2011. The extent and scope of these cuts is difficult to assess at this time. Any decrease in demand for new equipment or use of existing equipment will likely result in a decrease in demand of our products and services, and correspondingly, our revenues, thereby adversely affecting our business, financial condition and results of operations.

Our participation in specific major U.S. federal government programs is critical to both the development and sale of our defense robots. For example, in the years ended December 29, 2012 and December 31, 2011, 71.0% and 63.2% of our total contract revenue was derived from our participation in the U.S. Army’s BCTM program, respectively. The BCTM program was terminated in 2011 and additional work related to this program is currently funded through April 2013. Future sales of our military robots will depend largely on our ability to secure contracts with the U.S. military under its robot programs. We expect that there will continue to be only a limited number of programs under which U.S. federal government agencies will seek to fund the development of, or purchase, robots. Moreover, it is difficult to predict the timing of the award of government contracts and our revenue could fluctuate significantly based on the timing of any such awards.

Even if we continue to receive funding for research and development under these contracts, there can be no assurance that we will successfully complete the development of robots pursuant to these contracts or that, if successfully developed, the U.S. federal government or any other customer will purchase these robots from us. The U.S. federal government has the right when it contracts to use the technology developed by us to have robots supplied by third parties. Any failure by us to complete the development of these robots, or to achieve successful sales of these robots, would harm our business and results of operations. Our business and results of operations could be negatively affected by significant changes in the policies and spending priorities of governments and government agencies, and could result in restructuring charges related to workforce reductions, excess and obsolete inventory, impairment of asset values or other charges. Many of our government customers are

13

subject to stringent budgetary constraints and our continued performance under these contracts, or award of additional contracts from these agencies, could be jeopardized by spending reductions or budget cutbacks at these agencies.

Our contracts with the U.S. federal government contain certain provisions that may be unfavorable to us and subject us to government audits, which could materially harm our business and results of operations.

Our contracts and subcontracts with the U.S. federal government subject us to certain risks and give the U.S. federal government rights and remedies not typically found in commercial contracts, including rights that allow the U.S. federal government to:

• terminate contracts for convenience, in whole or in part, at any time and for any reason;

• reduce or modify contracts or subcontracts if its requirements or budgetary constraints change;

• cancel multi-year contracts and related orders if funds for contract performance for any subsequent year become unavailable;

• exercise production priorities, which allow it to require that we accept government purchase orders or produce products under its contracts before we produce products under other contracts, which may displace or delay production of more profitable orders;

• claim certain rights in products provided by us; and

• control or prohibit the export of certain of our products.

Several of our prime contracts with the U.S. federal government do 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 us, especially given the use to which our products may be put.

In addition, we are 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 our performance on contracts, cost structures and compliance with applicable laws, regulations and standards. If any of our 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. Moreover, if an audit uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or debarment from doing business with the government.

If any of the foregoing were to occur, or if the U.S. federal government otherwise ceased doing business with us or decreased the amount of business with us, our business and operating results could be materially harmed and the value of your investment in our common stock could be impaired.

Some of our contracts with the U.S. federal government allow it to use inventions developed under the contracts and to disclose technical data to third parties, which could harm our ability to compete.

Some of our contracts allow the U.S. federal government rights to use, or have others use, patented inventions developed under those contracts on behalf of the government. Some of the contracts allow the federal government to disclose technical data without constraining the recipient in how that data is used. The ability of third parties to use patents and technical data for government purposes creates the possibility that the government could attempt to establish additional sources for the products we provide that stem from these contracts. It may also allow the government the ability to negotiate with us to reduce our prices for products we provide to it. The potential that the government may release some of the technical data without constraint creates the possibility that third parties may be able to use this data to compete with us in the commercial sector.

We depend on single source 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 contract manufacturers, for the manufacture of our various families of home care and defense products. All contract manufacturers for our home robots are located in China. These manufacturers supply substantially 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, we would be unable to manufacture 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.

Our reliance on these contract manufacturers involves certain risks, including the following:

• lack of direct control over production capacity and delivery schedules;

14

• 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

• 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, while our contract obligations with our contract manufacturers in China are typically denominated in U.S. dollars, changes in currency exchange rates could impact our suppliers and increase our prices.

Any efforts to expand our product offerings beyond our current markets may not succeed, which could negatively impact our operating results.

We have focused on selling our robots in the home floor care and defense markets. We plan to expand into other markets. Efforts to expand our product offerings beyond the markets that we currently serve, however, 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.

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 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, restructurings, 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 home care robot sales.

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.

We believe that a number of companies have developed or are developing robots that will compete directly with our product offerings. Additionally, large and small companies, government-sponsored laboratories and universities are aggressively pursuing contracts for robot-focused research and development. Many current and potential competitors have 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. 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 in some cases with providers of traditional vacuum cleaners. Our competitors include developers of robot floor cleaning products, developers of small unmanned ground vehicles, and established government contractors working on unmanned systems.

The 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, 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

15

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.

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 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 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 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.

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. Moreover, because military robots are used in dangerous situations, the failure or malfunction of any of these robots, including our own, could significantly damage our reputation and support for robot solutions in general. 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.

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. 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 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.

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 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

16

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.

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. 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. Some of our contracts with the U.S. federal government allow the federal government to disclose technical data regarding the products developed on behalf of the government under the contract without constraining the recipient on how it is used. This ability of the government creates the potential that third parties may be able to use this data to compete with us in the commercial sector. 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. We may be required to expend significant resources to monitor and protect our intellectual property rights. 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.

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. 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.

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. Moreover, we often must comply with provisions in government contracts that require employment of persons with specified levels of education and work experience. 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.

17

We are subject to extensive U.S. federal government regulation, and our failure to comply with applicable regulations could subject us to penalties that may restrict our ability to conduct our business.

As a contractor and subcontractor to the U.S. federal government, we are subject to and must comply with various government regulations that impact our operating costs, profit margins and the internal organization and operation of our business. Among the most significant regulations affecting our business are:

• the Federal Acquisition Regulations and supplemental agency regulations, which comprehensively regulate the formation and administration of, and performance under government contracts;

• the Truth in Negotiations Act, which requires certification and disclosure of all cost and pricing data in connection with contract negotiations;

• the Cost Accounting Standards, which impose accounting requirements that govern our right to reimbursement under cost-based government contracts;

• the Foreign Corrupt Practices Act, which prohibits U.S. companies from providing anything of value to a foreign official to help obtain, retain or direct business, or obtain any unfair advantage;

• the False Claims Act and the False Statements Act, which, respectively, impose penalties for payments made on the basis of false facts provided to the government, and impose penalties on the basis of false statements, even if they do not result in a payment;

• laws, regulations and executive orders restricting the use and dissemination of information classified for national security purposes and the exportation of certain products and technical data;

• Certain contracts from the U.S. federal government may require us to maintain certain certifications including but not limited to AS9100 and CMMI;

• Contractor Purchasing Systems review (CPSR) requirements, which evaluate the efficiency and effectiveness with which we spend U.S. Government funds; and

• The sale of our products in countries outside the United States is regulated by the governments of those countries. While compliance with such regulation will generally be undertaken by our international distributors, we may assist with such compliance and in certain cases may be liable if a distributor fails to comply.

We must comply with U.S. laws regulating the export of our products. In addition, we are required to obtain a license from the U.S. federal government to export our PackBot, Warrior, FirstLook and SUGV lines of tactical military robots. We cannot be sure of our ability to obtain any licenses required to export our products or to receive authorization from the U.S. federal government for international sales or domestic sales to foreign persons. Moreover, the export regimes and the governing policies applicable to our business are subject to change. We cannot assure you of the extent that such export authorizations will be available to us, if at all, in the future. In some cases where we act as a subcontractor, we rely upon the compliance activities of our prime contractors, and we cannot assure you that they have taken or will take all measures necessary to comply with applicable export laws. If we or our prime contractor partners cannot obtain required government approvals under applicable regulations in a timely manner or at all, we would be delayed or prevented from selling our products in international jurisdictions, which could materially harm our business, operating results and ability to generate revenue.

Also, we need special clearances to continue working on and advancing certain of our projects with the U.S. federal government. Obtaining and maintaining security clearances for employees involves a lengthy process, and it is difficult to identify, recruit and retain employees who already hold security clearances. If our employees are unable to obtain security clearances in a timely manner, or at all, or if our employees who hold security clearances are unable to maintain the clearances or terminate employment with us, then a customer requiring classified work could terminate the contract or decide not to renew it upon its expiration. In addition, we expect that many of the contracts on which we will bid will require us to demonstrate our ability to obtain facility security clearances and employ personnel with specified types of security clearances. To the extent we are not able to obtain facility security clearances or engage employees with the required security clearances for a particular contract, we may not be able to bid on or win new contracts, or effectively rebid on expiring contracts. Classified programs generally will require that we comply with various Executive Orders, federal laws and regulations and customer security requirements that may include restrictions on how we develop, store, protect and share information, and may require our employees to obtain government clearances.

Our failure to comply with applicable regulations, rules and approvals could result in the imposition of penalties, the loss of our government contracts or our suspension or debarment from contracting with the federal government generally, any of which would harm our business, financial condition and results of operations.

18

Acquisitions and potential future acquisitions could be difficult to integrate, divert the attention of key personnel, disrupt our business, dilute stockholder value and impair our financial results.

As part of our business strategy, we have in the past acquired, and we intend to continue to consider additional acquisitions of companies, technologies and products that we believe could accelerate our ability to compete in our core markets or allow us to enter new markets. For example, in October 2012, we acquired Evolution Robotics, Inc. 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, 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 a future acquisition or combination. 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.

In addition, 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 and non-income 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;

• charges to our operating results to eliminate certain duplicative pre-merger activities, to restructure our operations or to reduce our cost structure;

• charges to our operating results resulting from expenses incurred to effect the acquisition; and

• charges to our operating results due to the expensing of certain stock awards assumed in an acquisition.

We may fail to realize anticipated benefits from our acquisition of Evolution Robotics.

The success of our acquisition of Evolution Robotics will depend, in part, on our ability to realize the anticipated synergies, business opportunities and growth prospects from combining our business with that of Evolution Robotics. We may never realize these anticipated synergies, business opportunities and growth prospects. Assumptions underlying estimated benefits may be inaccurate and general industry and business conditions might deteriorate. Our management might have its attention diverted while trying to integrate operations and corporate and administrative infrastructures from the Evolution Robotics architecture into the correlative iRobot systems. If any of these factors limit our ability to integrate Evolution Robotics into our operations successfully or on a timely basis, the expectations of future results of operations, including synergies and other benefits expected to result from the Evolution Robotics acquisition, might not be met.

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, will be sufficient to meet our current and anticipated needs for general corporate purposes. We operate in an emerging 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

19

would be significantly limited. In addition, our access to credit through our working capital line of credit may be limited by the restrictive financial covenants contained in that agreement, which require us to maintain profitability.

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 Far East markets, and Canada. For the fiscal years ended December 29, 2012 and December 31, 2011, sales to non-U.S. customers accounted for 57.3% and 45.5% of total revenue, respectively. 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 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

• outside of the United States, we primarily rely on a network of exclusive 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 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.

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.

If we suffer any data breaches involving the designs, schematics or source code for our products, our 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. In addition, we work with e-commerce providers who hold significant sensitive customer data. 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

20

implementation of additional security measures, either of which could materially and adversely affect our business and financial results.

The effects of new 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 will require companies to diligence, disclose and report whether or not such minerals originate from the Democratic Republic of Congo and adjoining countries. We will have to diligence whether such minerals are used in the manufacture of our products.  However, the implementation of these new 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 will 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.  The first report is due on May 31, 2014 for the 2013 calendar year.  Recently, the U.S. Chamber of Commerce, the National Association of Manufacturers and the Business Roundtable filed a petition challenging the adoption of the rules by the SEC.  It is presently unclear if this challenge will delay the effectiveness of the rule.

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 and local authorities regarding income tax matters. Significant judgment is required to determine our provision for income taxes and our liabilities for federal, state, local and other taxes. Although we believe our approach to determining the appropriate tax treatment is supportable and in accordance with relevant authoritative guidance it is possible that the final tax authority will take a tax position that is materially different than that which is reflected in our income 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 taxable 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.

Provisions in our certificate of incorporation and by-laws, our shareholder rights agreement 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.

We have also adopted a shareholder rights agreement that entitles our stockholders to acquire shares of our common stock at a price equal to 50% of the then-current market value in limited circumstances when a third party acquires or announces its intention to acquire 15% or more of our outstanding common stock.

21

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.

ITEM 1B.    UNRESOLVED STAFF COMMENTS  

None.

ITEM 2.    PROPERTIES 

Our corporate headquarters are located in Bedford, Massachusetts, where we lease approximately 183,000 square feet. This lease expires on May 1, 2020.

We do not own any real property. We believe that our leased facilities and additional or alternative space available to us will be adequate to meet our needs for the foreseeable future.

ITEM 3.    LEGAL PROCEEDINGS 

From time to time and in the ordinary course of business, we are 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.

ITEM 4.    MINE SAFETY DISCLOSURES

Overview

iRobot designs and builds robots that make a difference. For over 20 years, we have developed proprietary technology incorporating advanced concepts in navigation, mobility, manipulation and artificial intelligence to build industry-leading robots. Our Roomba floor vacuuming robot, Scooba floor washing robot and Mint floor sweeping robot perform time-consuming domestic chores in the home, while our Looj gutter cleaning robot and Verro pool cleaning robot perform tasks outside the home. Our PackBot and Small Unmanned Ground Vehicle (SUGV) tactical ground military robots perform battlefield reconnaissance and bomb disposal. We sell our robots to consumers through a variety of distribution channels, including chain stores and other national retailers, and through our on-line store, and to the U.S. military and other government agencies worldwide. We maintain certifications for AS9100 for certain programs within our defense and security business unit.

As of December 29, 2012, we had 534 full-time employees. We have developed expertise in the disciplines necessary to build 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, reducing the time, cost and risk of product development. Our significant expertise in robot design and engineering, combined with our management team’s experience in defense and consumer markets, positions us to capitalize on the expected growth in the market for robots.

Although we have successfully launched consumer and defense and security products, our continued success depends upon our ability to respond to a number of future challenges. We believe the most significant of these challenges include increasing competition in the markets for both our consumer and defense and security products, our ability to obtain U.S. federal government funding for research and development programs, and our ability to successfully develop and introduce products and product enhancements.

Our total revenue for 2012 was $436.2 million, which represents a 6% decrease from 2011 revenue of $465.5 million. Revenue for 2012 in our home robots business increased $78.2 million compared to 2011 and represented 82% of our total 2012 revenue compared to 60% in 2011. The increase in home robots revenue was the result of growth in both domestic and international markets. Revenue for 2012 in our defense and security business decreased by $107.5 million compared to 2011 as a direct result of troop withdrawals in Afghanistan, program cancellations and ongoing budget reductions within the U.S. government. We anticipate that our business performance over the next few years will be primarily driven by our rapidly growing home technology business and expect that our home robots revenue will comprise approximately 90% of our total revenue in the near term.

During 2012, we recorded favorable adjustments to our home robots business revenue resulting from reductions to our defective returns provision that were directly attributable to lower defective returns experience and contractual modifications limiting our defective returns liability with certain customers. We also recorded favorable adjustments to our cost of product revenue relating to reductions in our international warranty accrual for our home robots business that were directly attributable to declining warranty cost experience. Both the lower defective returns and warranty cost experience are related to our sustained improvements in product quality for which we expect to receive continuing benefits in the foreseeable future. Offsetting these favorable adjustments were increases to our product cost of revenue resulting from reserves established for excess inventory caused by the significant reduction in sales in our defense and security business during the year. Additionally, we recorded restructuring charges during 2012 associated with the write-off of certain assets and the recording of severance related costs, the majority of which related to a realignment of our cost structure due to the decline in our defense and security business. Additionally, we closed our North Carolina office, where our Maritime business formerly operated, and moved the research component of that business to our Bedford, Massachusetts location. The net impact of these adjustments was an increase to our 2012 net income and earnings per share of approximately $6.6 million and $0.23, respectively.

On October 1, 2012, we acquired privately-held Evolution Robotics, Inc., the developer of Mint and Mint Plus automatic floor cleaning robots based in Pasadena, California, for approximately $74.5 million, net of cash received. Our 2012 net income and earnings per share were negatively impacted by $4.7 million and $0.17, respectively, as a result of the inclusion of Evolution Robotics operations as of the October 1, 2012 acquisition date. We currently expect the Evolution Robotics operations to have a dilutive effect on our earnings through the third quarter of 2013 and to become accretive beginning in the fourth quarter of 2013.

Revenue

We currently derive revenue from product sales, government research and development contracts, and commercial research and development contracts. Product revenue is derived from the sale of our various home cleaning robots and defense and security robots and related accessories. Research and development revenue is derived from the execution of contracts awarded by the U.S. federal government, other governments and a small number of other partners. In the future, we expect to derive increasing revenue from product maintenance and support services due to a focused effort to market these services to the expanding installed base of our robots.

We currently derive a majority of our product revenue from the sale of our home cleaning robots, and to a lesser extent, our PackBot and SUGV tactical military robots. For the fiscal years ended December 29, 2012 and December 31, 2011, product revenues accounted for 95.9% and 91.6% of total revenue, respectively. For the fiscal years ended December 29, 2012 and December 31, 2011, our funded research and development contracts accounted for approximately 4.1% and 8.4% of our total revenue, respectively. We expect to continue to perform funded research and development work with the intent of leveraging the technology developed to advance our new product development efforts. In the future, based on changes in operational needs from the U.S. armed forces, and significant pressures on U.S. spending levels, we anticipate that revenue from product sales to the U.S. armed forces will decrease in the near term. In addition, we expect that revenue from funded research and development contracts could decrease on an absolute dollar basis.

For the fiscal years ended December 29, 2012 and December 31, 2011, approximately 75.4% and 74.0%, respectively, of our home robot product revenue resulted from sales to 15 customers. For fiscal 2012 and fiscal 2011, the customers were comprised of both U.S. retailers and international distributors. Direct-to-consumer revenue generated through our domestic and international on-line stores accounted for 6.3% of our home robot product revenue for the fiscal year ended December 29, 2012 compared to 9.6% in the fiscal year ended December 31, 2011. We typically sell our recently launched products direct on-line, and then subsequently offer these products through other channels of distribution. In addition, 79.5% and 88.4% of defense product revenue, and 95.2% and 95.7% of funded research and development contract revenue, resulted from orders and contracts or subcontracts with the U.S. federal government in the fiscal years ended December 29, 2012 and December 31, 2011, respectively.

For the fiscal years ended December 29, 2012 and December 31, 2011, sales to non-U.S. customers accounted for 57.3% and 45.5% of total revenue, respectively.

26

Our revenue from product sales is generated through sales to our retail distribution channels, our distributor network and to certain U.S. and foreign governments. We recognize revenue from the sales of home robots under the terms of the customer agreement upon transfer of title and risk of loss to the customer, net of estimated returns, provided that collection is determined to be reasonably assured and no significant obligations remain. During 2012, we recorded favorable adjustments to our home robots business revenue resulting from reductions to our defective returns provision that were directly attributable to lower defective returns experience and contractual modifications limiting our defective returns liability with certain customers.

Revenue from our defense and security robot sales and revenue from funded research and development contracts are occasionally influenced by the September 30 fiscal year-end of the U.S. federal government. In addition, our revenue can be affected by the timing of the release of new products and the size and timing of contract awards from defense and other government agencies. Historically, revenue from consumer product sales has been significantly seasonal, with a majority of our consumer product revenue generated in the second half of the year (in advance of the holiday season). As a result of the growth of our international consumer business, which is less seasonal than our domestic consumer business, our consumer product revenue is currently spread more evenly throughout the year.

Cost of Revenue

Cost of product revenue includes the cost of raw materials and labor that go into the development and manufacture of our products as well as manufacturing overhead costs such as manufacturing engineering, quality assurance, logistics and warranty costs. For the fiscal years ended December 29, 2012 and December 31, 2011, cost of product revenue was 57.3% and 57.9% of total product revenue, respectively. The decrease in cost of product revenue as a percentage of revenue was driven primarily byunfavorable absorption of our overhead expense against lower revenue, restructuring charges, scrap, rework and excess and obsolete inventory costs in our defense and security business unit, offset by a shift in our product mix to higher margin home robot products and favorable adjustments relating to reductions in our international warranty accrual for our home robots business that were directly attributable to declining warranty cost experience. 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. We outsource the manufacture of our home robots to contract manufacturers in China. While labor costs in China traditionally have been favorable compared to labor costs elsewhere in the world, including the United States, we believe that labor in China is becoming more scarce. In addition fluctuations in currency exchange rates could increase the cost of labor. Consequently, the labor costs for our home robots could increase in the future.

Cost of contract revenue includes the direct labor costs of engineering resources committed to funded research and development contracts, as well as third-party consulting, travel and associated direct material costs. Additionally, we include overhead expenses such as indirect engineering labor, occupancy costs associated with the project resources, engineering tools and supplies and program management expenses. For the fiscal years ended December 29, 2012 and December 31, 2011, cost of contract revenue was 94.9% and 67.9% of total contract revenue, respectively.

Gross Margin

Our gross margin as a percentage of revenue varies according to the mix of product and contract revenue, the mix of products sold, total sales volume, the level of defective product returns, and levels of other product costs such as warranty, scrap, re-work and manufacturing overhead. For the years ended December 29, 2012 and December 31, 2011, gross margin was 41.2% and 41.3% of total revenue, respectively. The decrease in margin was driven primarily by unfavorable absorption of our overhead expense against lower revenue, restructuring charges, scrap, rework and excess and obsolete inventory costs in our defense and security business unit, offset by product mix to higher margin home robot products, favorable adjustments to our return provision due to gradual improvement in returns resulting from sustained investment in product quality, and favorable adjustments relating to reductions in our international warranty accrual for our home robots business that were directly attributable to declining warranty cost experience.

Research and Development Expenses

Research and development expenses consist primarily of:

• salaries and related costs for our engineers;

• costs for high technology components used in product and prototype development; and

• costs of test equipment used during product development.

We have significantly expanded our research and development capabilities and expect to continue to expand these capabilities in the future. We are committed to consistently maintaining the level of innovative design and development of new products as we strive to enhance our ability to serve our existing consumer and military markets as well as new markets for

27

robots. We anticipate that research and development expenses will increase in absolute dollars but remain relatively consistent as a percentage of revenue in the foreseeable future.

For the fiscal years ended December 29, 2012 and December 31, 2011, research and development expense was $37.2 million and $36.5 million, or 8.5% and 7.8% of total revenue, respectively.

In addition to our internal research and development activities discussed above, we incur research and development expenses under funded development arrangements with both governments and other third parties. For the fiscal years ended December 29, 2012 and December 31, 2011, these expenses amounted to $16.8 million and $26.5 million, respectively. In accordance with generally accepted accounting principles, these expenses have been classified as cost of revenue rather than research and development expense. For the years ended December 29, 2012 and December 31, 2011, the combined investment in future technologies, classified as cost of revenue and research and development expense, was $54.0 million and $63.0 million, respectively.

Selling, General and Administrative Expenses

Our selling, general and administrative expenses consist primarily of:

• salaries and related costs for sales and marketing personnel;

• salaries and related costs for executives and administrative personnel;

• advertising, marketing and other brand-building costs;

• fulfillment costs associated with direct-to-consumer sales through our on-line store;

• customer service costs;

• professional services costs;

• information systems and infrastructure costs;

• travel and related costs; and

• occupancy and other overhead costs.

We anticipate that selling, general and administrative expenses will increase in absolute dollars but remain relatively consistent as a percentage of revenue in the foreseeable future as we continue to build the iRobot brand and also maintain company profitability.

For the fiscal years ended December 29, 2012 and December 31, 2011, selling, general and administrative expense was $117.3 million and $102.3 million, or 26.9% and 22.0% of total revenue, respectively.

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.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates.

We believe that of our significant accounting policies, which are described in the notes to our consolidated financial statements, the following accounting policies involve a greater degree 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 results of operations.

Revenue Recognition

We recognize revenue from sales of consumer products under the terms of the customer agreement upon transfer of title and risk of loss to the customer, which is typically upon the delivery of the product, provided the price is fixed or determinable, collection is determined to be reasonably assured and no significant obligations remain. Sales to domestic resellers are typically subject to agreements allowing for limited rights of return for defective products only, rebates and price protection. Accordingly, we reduce revenue for our estimates of liabilities for these rights of return at the time the related sale is recorded. We establish a provision for sales returns for products sold by domestic resellers directly based on historical return experience and other relevant data. Our international distributor agreements do not currently allow for product returns and, as a result, no reserve for returns is established for this group of customers. We have aggregated and analyzed historical returns from domestic resellers and end users which form the basis of our estimate of future sales returns by resellers or end users. When a right of return exists, the provision for these estimated returns is recorded as a reduction of revenue at the time that the related revenue

28

is recorded. If actual returns from retailers differ significantly from our estimates, such differences could have a material impact on our results of operations for the period in which the actual returns become known. Our returns reserve is calculated as a percentage of gross consumer product revenue. A small increase or decrease in our actual experience of returns could have a material impact on our quarterly and annual results of operations. The estimates for returns are adjusted periodically based upon historical rates of returns. The estimates and reserve for rebates and price protection are based on specific programs, expected usage and historical experience. Actual results could differ from these estimates. If future trends or our ability to estimate were to change significantly from those experienced in the past, incremental reductions or increases to revenue may result based on this new experience.

Under cost-plus research and development contracts, we recognize revenue based on costs incurred plus a pro-rata portion of the total fixed fee. Costs and estimated gross margins on contracts are recorded as work is performed based on the percentage that incurred costs bear to estimated total costs utilizing the most recent estimates of costs and funding. We recognize revenue on firm fixed price (FFP) contracts using the percentage-of-completion method. For government product FFP contracts, revenue is recognized as the product is shipped or in accordance with the contract terms. Changes in job performance, job conditions and estimated profitability, including those arising from final contract settlements and government audit, may result in revisions to costs and income, and are recorded or recognized, as the case may be, in the period in which the revisions are determined. Since many contracts extend over a long period of time, revisions in cost and funding estimates during the progress of work have the effect of adjusting earnings applicable to past performance in the current period. When the current contract estimate indicates a loss, provision is made for the total anticipated loss in the current period. Revenue earned in excess of billings, if any, is recorded as unbilled revenue. Billings in excess of revenue earned, if any, are recorded as deferred revenue.

Accounting for Stock-Based Awards

We recognized $4.6 million of stock-based compensation expense during the fiscal year ended December 29, 2012 for stock options. The unamortized fair value as of December 29, 2012 associated with these grants was $10.8 million with a weighted-average remaining recognition period of 2.54 years.

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 that we have never paid and have no present intention to pay cash dividends. Prior to 2010, the expected term calculation was based upon the simplified method provided under the relevant authoritative guidance. During 2010, we began to rely solely on company specific historical data to calculate the expected term. Given our initial public offering in November 2005 and the resulting short history as a public company, we could not rely solely on company specific historical data for purposes of establishing expected volatility. Consequently, prior to 2010, we performed an analysis that included company specific historical data combined with data of several peer companies with similar expected option lives to develop expected volatility assumptions. During 2010, we began to rely solely on company specific historical data for purposes of establishing expected volatility.

Based upon the above assumptions, the weighted average fair value of each stock option granted for the fiscal year ended December 29, 2012 was $13.23.

During the fiscal year ended December 29, 2012, the Company recognized $6.4 million of stock-based compensation associated with restricted stock units. Unamortized expense associated with restricted stock units at December 29, 2012, was $17.9 million.

We have assumed a forfeiture rate for all stock options, restricted stock awards and restricted stock-based units granted subsequent to the Company’s initial filing of its Form S-1 with the SEC. In the future, we will record incremental stock-based compensation expense if the actual forfeiture rates are lower than estimated and will record a recovery of prior stock-based compensation expense if the actual forfeitures are higher than estimated.

Accounting for stock-based awards requires significant judgment and the use of estimates, particularly surrounding assumptions such as stock price volatility and expected option lives to value equity-based compensation.

Accounting for Income Taxes

Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are provided if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

We monitor the realization of our deferred tax assets based on changes in circumstances, for example, recurring periods of income for tax purposes following historical periods of cumulative losses or changes in tax laws or regulations. Our income tax provision and our assessment of the ability to realize our deferred tax assets involve significant judgments and estimates. In fiscal 2012, as part of the accounting for our acquisition of Evolution Robotics, Inc., we recorded a valuation allowance of $2.7

29

million related to certain state tax attributes of Evolution Robotics, Inc. At December 29, 2012, we have total deferred tax assets of $30.6 million offset by a valuation allowance of $2.7 million.

Warranty

We typically provide a one-year warranty (with the exception of European consumer products which typically have a two-year warranty period and our defense and security spares which typically have a warranty period of less than one year) 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, 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.

Inventory Valuation

We value our inventory at the lower of the actual cost of our inventory or its current estimated market value. We write down inventory for obsolescence or unmarketable inventories based upon assumptions about future demand and market conditions. Actual demand and market conditions may be lower than those that we project and this difference could have a material adverse effect on our gross margin if inventory write-downs beyond those initially recorded become necessary. Alternatively, if actual demand and market conditions are more favorable than those we estimated at the time of such a write-down, our gross margin could be favorably impacted in future periods.

	(In thousands)
Total Revenue	$	436,244	$	465,500	$	(29,256	)	(6.3	)%

Our revenue decreased 6.3% to $436.2 million in fiscal 2012 from $465.5 million in fiscal 2011. Revenue increased approximately $78.2 million, or 28.1%, in our home robots business unit, and decreased $107.5 million, or 57.5%, in our defense and security business unit.

The $78.2 million increase in revenue from our home robots business unit was driven by an 18.2% increase in units shipped and a 7.2% increase in net average selling price. In fiscal 2012, international home robots revenue increased $43.3 million and domestic home robots revenue increased $34.9 million, including $3.8 million in the three month period ended December 29, 2012 related to the newly acquired Mint floor sweeping robot. Total home robots shipped in fiscal 2012 were 1,621,000 units compared to 1,371,000 units in fiscal 2011. The increase in home robots business unit revenue and units shipped was primarily attributable to a 22.1% increase in international sales of our home robots products and a 42.2% increase

31

in domestic sales of our home robots products. The increase in international sales is due primarily to increased demand in our Asian and European markets. The increase in demand was driven by demand for our new Roomba 700 series robot and the introduction of the Roomba 600 series robot, and an increase in marketing programs by us and our international distributors. The increase in domestic sales of our home robots products was primarily attributable to increased sales to domestic retail stores driven by the success of our recent domestic advertising campaign, expanded distribution of our Roomba 700 series robot and the introduction of the Roomba 600 series robot, and favorable adjustments to our return provision due to gradual improvement in returns resulting from sustained investment in product quality. In addition, net average selling prices in the home robots business unit increased due to increased volume of higher priced products including the Roomba 700 series robot, and fewer sales of our lower priced Roomba series.

The $107.5 million decrease in revenue from our defense and security robots business unit was driven by an $81.1 million decrease in defense and security robot revenue, a $21.3 million decrease in recurring contract development revenue generated under research and development contracts, and a $5.1 million decrease in product life cycle revenue (spare parts, accessories). The $81.1 million decrease in defense and security robots revenue was primarily due to a decrease in sales of higher price PackBot and SUGV units in 2012 as compared to 2011. Net average selling price decreased by 38.2% due to product mix primarily attributable to FirstLook units shipped in 2012 which have a lower selling price than the PackBot and SUGV units that comprised a larger portion of the units shipped in 2011. Total defense and security robots shipped in 2012 were 289 units compared to 773 units in 2011. The $21.3 million decrease in recurring contract development revenue generated under research and development contracts was primarily the result of decreases in government funding for our SUGV, Research and Maritime programs. The $5.1 million decrease in product life cycle revenue is due to reduction in spares associated with lower robot sales and a decrease in PackBot upgrades. Continued funding delays for government contracts have reduced our near-term visibility in our defense and security robots business unit and contributed to the decrease in period-over-period revenue in this business unit. We cannot predict with any certainty the extent to which these funding delays will continue.

Gross margin decreased $12.4 million, or 6.5%, to $179.7 million (41.2% of revenue) in fiscal 2012 from $192.1 million (41.3% of revenue) in fiscal 2011. The decrease in gross margin as a percentage of revenue was the result of the home robots business unit gross margin increasing 4.3 percentage points offset by the defense and security robots business unit gross margin decreasing 31.5 percentage points. The 4.3 percentage point increase in the home robots business unit is attributable to favorable adjustments to our return provision due to gradual improvement in returns resulting from sustained investment in product quality, changes in customer and product mix to higher margin home robots products including the introduction of our Roomba 700 series and Scooba 230 robots, favorable adjustments relating to reductions in our international warranty accrual for our home robots business that were directly attributable to declining warranty cost experience, and improved leverage of our overhead expense against higher revenue in fiscal 2012 as compared to fiscal 2011. The 31.5 percentage point decrease in the defense and security robots business unit is primarily attributable to unfavorable absorption of our overhead expense against lower revenue, restructuring charges, scrap, rework and excess and obsolete inventory costs in fiscal 2012 as compared to fiscal

32

2011, and product mix primarily attributable to the lower-margin FirstLook units shipped in fiscal 2012 compared to PackBot and SUGV units shipped in fiscal 2011.

Research and development expenses increased $0.7 million, or 2.0%, to $37.2 million (8.5% of revenue) in fiscal 2012 from $36.5 million (7.8% of revenue) in fiscal 2011. The increase in research and development expenses is primarily due to increases in compensation, contractor, consultants and material associated with internal research and development projects in our home robots business unit partially offset by reduced compensation, contractor, consultants and material expense in our defense and security business unit. The increase in our home robots business unit is primarily the result of increased efforts in the areas of product development, including our efforts associated with the RP-VITA (Remote Presence Virtual + Independent Telemedicine Assistant) product that was jointly developed with, and is sold by, InTouch Technologies, Inc.

In addition to our research and development activities classified as research and development expense, we incur research and development expenses under funded development arrangements with governments and industrial third parties. For fiscal 2012, these expenses amounted to $16.8 million, compared to $26.5 million for fiscal 2011. These expenses have been classified as cost of revenue rather than research and development expense. The combined investment in future technologies, classified as cost of revenue and research and development expense, was $54.0 million for fiscal 2012, compared to $63.0 million for fiscal 2011.

Income tax provision	$	8,310		$	13,350		$	(5,040	)	(37.8	)%
As a percentage of pre-tax income	32.5		%	24.9		%

We recorded a tax provision of $8.3 million and $13.4 million for fiscal 2012 and fiscal 2011, respectively. The $8.3 million provision for fiscal 2012 was based upon a 2012 effective income tax rate of 30.3% plus a net tax expense of $0.6 million primarily resulting from the true-up of prior year permanent items. The $13.4 million provision for fiscal 2011 was based upon a 2011 effective income tax rate of 29.7% offset primarily by a net tax benefit of $3.5 million resulting from the completion in the period of a comprehensive evaluation of our research and development credit and domestic manufacturing deductions.

In January 2013, legislation was enacted that included the extension of the research and development tax credit. The legislation retroactively reinstated the research and development tax credit for 2012 and extended it through December 31, 2013. As a result, we expect to record a discrete benefit of approximately $1.8 million related to 2012 in 2013 and an annual benefit of $2.8 million related to 2013.

The increase in the effective tax rate from 29.7% in 2011 to 30.3% in 2012 was primarily due to the expiration of the federal research and development credit, offset by a decrease in state taxes and a higher domestic manufacturing deduction as a percentage of income before taxes in 2012 as compared with 2011.

Total Revenue	$	465,500	$	400,952	$	64,548	16.1	%

Our revenue increased 16.1% to $465.5 million in fiscal 2011 from $401.0 million in fiscal 2010. Revenue increased approximately $49.2 million, or 21.5%, in our home robots business unit and $15.3 million, or 8.9%, in our defense and security business unit.

The $49.2 million increase in revenue from our home robots business unit was driven by an 8.0% increase in units shipped and a 13.2% increase in net average selling price. In fiscal 2011, international home robots revenue increased $44.3 million and domestic home robots revenue increased $4.9 million. Total home robots shipped in fiscal 2011 were 1,371,000 units compared to 1,269,000 units in fiscal 2010. The increase in home robots business unit revenue and units shipped was primarily attributable to international sales increasing 29.3% due to increased demand in our European and Asian markets. The increase in demand was driven by demand for our new Roomba 700 series robot, an increase in marketing programs by us and our international distributors and continued efforts to increase international retail outlets for our home robots products across various countries. Domestic retail sales of our home robot products increased 7.9% and domestic direct sales through our website increased 2.3% in fiscal 2011 as compared to fiscal 2010. The increase in domestic retail demand is due in part to our increased and sustained domestic marketing activities which began in the fourth quarter of 2010. The increase in our direct to consumer sales through our website was driven by the introduction of our Roomba 700 series and Scooba 230

34

robots. Home robots business unit revenue from international sales was 70.3% of total home robots business unit revenue in fiscal 2011 as compared to 66.0% in fiscal 2010. The increase in net average selling prices was primarily driven by customer mix and product mix relating to the introduction of our Roomba 700 series and Scooba 230 robots.

The $15.3 million increase in revenue from our defense and security robots business unit was driven by a $4.5 million increase in product life cycle revenue (spare parts, accessories) and a $12.5 million increase in defense and security robot revenue offset by a $1.6 million decrease in recurring contract development revenue generated under research and development contracts. The $4.5 million increase in product life cycle revenue is the result of a higher installed base of our defense and security robots. The $1.6 million decrease in recurring contract development revenue generated under research and development contracts was primarily the result of decreases in funding and timing of work efforts for our Maritime and Warrior programs. The $12.5 million increase in defense and security robots revenue was primarily due to a 27.7% increase in net average selling prices partially offset by a 11.3% decrease in units shipped in fiscal 2011 as compared to fiscal 2010. The increase in net average selling price was due to product mix primarily attributable to PackBot and SUGV units with a higher selling price shipped in fiscal 2011 as compared to lower priced PackBot FasTac units and lower priced configuration of SUGV units shipped in fiscal 2010. Total defense and security robots shipped in fiscal 2011 were 773 units compared to 871 units in fiscal 2010.

Gross margin increased $46.7 million, or 32.1%, to $192.1 million (41.3% of revenue) in fiscal 2011 from $145.4 million (36.3% of revenue) in fiscal 2010. The increase in gross margin as a percentage of revenue was the result of the home robots business unit gross margin increasing 5.2 percentage points and the defense and security robots business unit gross margin increasing 4.3 percentage points. The 5.2 percentage point increase in the home robots business unit is attributable to changes in customer and product mix to higher margin home robots products including the introduction of our Roomba 700 series and Scooba 230 robots, improved leverage of our overhead expense against higher revenue, and lower return provisions and warranty expense in fiscal 2011 as compared to fiscal 2010. The 4.3 percentage point increase in the defense and security robots business unit is primarily due to lower overhead expenses with improved leverage of our overhead expense against higher revenue, lower sustaining engineering expense and lower warranty expense in fiscal 2011 as compared to fiscal 2010.

Research and development expenses increased by $11.7 million, or 47.1%, to $36.5 million (7.8% of revenue) in fiscal 2011. This was driven by increases in our home robots business unit of $8.8 million, defense and security robots business unit of $1.8 million and other research and development expense of $1.1 million primarily relating to ongoing development of our common software platform. The increase in other research and development expense is due to increases in compensation and

35

benefits, consulting and materials associated with internal research and development projects in both our home robots and defense and security robots business units. The increase in our home robots business unit is primarily the result of our increased efforts in the areas of new product development. The increase in our defense and security robots business unit is the result of our increased efforts in product development relating to our FirstLook, PackBot and Warrior programs.

In addition to our research and development activities classified as research and development expense, we incur research and development expenses under funded development arrangements with governments and industrial third parties. For fiscal 2011, these expenses amounted to $26.5 million, compared to $27.1 million for fiscal 2010. In accordance with generally accepted accounting principles, these expenses have been classified as cost of contract revenue rather than research and development expense. The combined investment in future technologies, classified as cost of revenue and research and development expense, was $63.0 million for fiscal 2011, compared to $51.9 million for fiscal 2010.

This was driven by an increase in our home robots business unit of $6.4 million primarily attributable to increases in advertising as part of our continued global marketing and branding efforts, other marketing, compensation, and employee-related expense for fiscal 2011 as compared to fiscal 2010. Selling and marketing expenses in our defense and security robots business unit increased by $1.2 million attributable to an increase in compensation, trade show, depreciation related to demonstration robots and travel expenses in fiscal 2011.

In fiscal 2012, we expect to continue to invest in sales and marketing to increase brand awareness. Accordingly, we anticipate selling and marketing expenses will increase in absolute dollars but remain at the same level or slightly above fiscal 2011 as a percentage of revenue.

We recorded a tax provision of $13.4 million and $8.5 million for fiscal 2011 and fiscal 2010, respectively. The $13.4 million provision for fiscal 2011 was based upon a 2011 effective income tax rate of 29.7% offset primarily by a net tax benefit of $3.5 million resulting from the completion in the period of a comprehensive evaluation of our research and development credit and domestic manufacturing deductions. The $8.5 million provision for fiscal 2010 was based upon a projected 2010 effective tax rate of 31.5% offset by a $2.3 million one-time benefit associated with the full release of our valuation allowance relating to state deferred tax assets.

The decrease in the projected effective tax rates from 31.5% in 2010 to 29.7% in 2011 was primarily due to higher domestic manufacturing deductions in 2011, partially offset by the release of our valuation allowance relating to state deferred tax assets in fiscal 2010.

Liquidity and Capital Resources

At December 29, 2012, our principal sources of liquidity were cash and cash equivalents totaling $126.8 million, short-term investments of $12.4 million and accounts receivable of $29.4 million.

We manufacture and distribute our products through contract manufacturers and third-party logistics providers. We believe that this approach gives us the advantages of relatively low capital investment and significant flexibility in scheduling production and managing inventory levels. By leasing our office facilities, we also minimize the cash needed for expansion. Accordingly, our capital spending is generally limited to leasehold improvements, computers, office furniture, product-specific production tooling, internal use software and test equipment. In the fiscal years ended December 29, 2012 and December 31, 2011, we spent $6.8 million and $13.0 million, respectively, on capital equipment.

Our strategy for delivering home robots products to our distributors and retail customers gives us the flexibility to provide container shipments directly to the retailer from China and, alternatively, allows our distributors and retail partners to take possession of product on a domestic basis. Accordingly, our home robots product inventory consists of goods shipped to our third-party logistics providers for the fulfillment of distributor, retail and direct-to-consumer sales. Our inventory of defense and security products consists mostly of components, as finished goods are generally built to order. Our contract manufacturers are also responsible for purchasing and stocking components required for the production of our products, and they typically invoice us when the finished goods are shipped.

The balance of cash, cash equivalents and short-term investments of $139.2 million at December 29, 2012 is primarily the result of our on-going focus on managing working capital. In 2012, we generated $37.9 million of cash from operations and we made investments of $82.4, including $74.5 million for the acquisition of Evolution Robotics, Inc. and $6.0 million for an equity interest in InTouch Technologies, Inc. As of December 29, 2012, we did not have any borrowings outstanding under our working capital line of credit and had $1.5 million in letters of credit outstanding under our revolving letter of credit facility.

Discussion of Cash Flows

Net cash provided by operating activities for the fiscal year ended December 29, 2012 was $37.9 million, a decrease of $17.9 million compared to the $55.7 million of net cash provided by operating activities for the fiscal year ended December 31, 2011. The decrease in net cash provided by operating activities was primarily driven by a decrease in cash of $22.9 million resulting from net income of $17.3 million in 2012 compared to net income of $40.2 million in 2011, as well as a decrease in cash of $18.4 million resulting from a decrease in accounts payable of $8.7 million in fiscal 2012 compared to a $9.7 million increase in accounts payable in fiscal 2011 as a result of normal purchasing and vendor payment activities, and a decrease of $9.9 million resulting from an increase in deferred tax assets of $3.8 million in 2012 compared to a decrease of $6.2 million in 2011, primarily due to the addition of deferred tax assets associated with the acquisition of Evolution Robotics and the net effect of changes in deferred tax assets and liabilities associated with operating assets and liabilities. These decreases were partially offset by an increase in cash of $24.4 million resulting from a decrease in accounts receivable (including unbilled revenue) of $16.7 million in fiscal 2012 compared to an increase of $7.6 million in 2011, primarily due to a decline in fiscal 2012 revenue and a reduction in the 2012 DSO (days sales outstanding) to 28 days from 32 days in 2011, as well as other net increases of $8.9 million due to normal operating activities.

37

Net cash used in investing activities for the fiscal year ended December 29, 2012 was $82.4 million, representing an increase of $65.2 million compared to the $17.2 million of net cash used in investing activities for the fiscal year ended December 31, 2011. This increase in net cash used in investing activities was primarily driven by the purchase of Evolution Robotics, Inc. in 2012 for net cash of $74.5 million and an investment of $6.0 million in preferred shares of InTouch Technologies, Inc. in 2012. These increases were partially offset by proceeds from the net sale of investments of $4.9 million in 2012 compared to the net purchase of investments of $4.2 million in 2011, as well as a decrease in purchases of property and equipment of $6.2 million from fiscal 2011 to fiscal 2012 primarily due to a decrease in spending on self-constructed and demonstration assets, leasehold improvements and internal use software.

Net cash provided by financing activities for the fiscal year ended December 29, 2012 was $5.0 million, a decrease of $14.4 million compared to the $19.4 million of net cash provided by financing activities for the fiscal year ended December 31, 2011. The decrease is due primarily to a decrease in proceeds from stock option exercises of $9.1 million and a decrease in the tax benefit associated with excess stock-based compensation deductions of $5.5 million.

Working Capital Facilities

Credit Facility

We have an unsecured revolving credit facility with Bank of America, N.A., which is available to fund working capital and other corporate purposes. As of December 29, 2012, the total amount available for borrowing under our credit facility was $75.0 million and the full amount was available for borrowing. The interest on loans under our credit facility accrues at a rate between LIBOR plus 1% and LIBOR plus 1.5%, based on our ratio of indebtedness to Adjusted EBITDA, and the credit facility termination date is June 30, 2014.

As of December 29, 2012, we had no outstanding borrowings under our working capital line of credit. This credit facility contains customary terms and conditions for credit facilities of this type, including restrictions on our ability to incur or guaranty additional indebtedness, create liens, enter into transactions with affiliates, make loans or investments, sell assets, pay dividends or make distributions on, or repurchase, our stock, and consolidate or merge with other entities.

This credit facility contains customary events of default, including for payment defaults, breaches of representations, breaches of affirmative or negative covenants, cross defaults to other material indebtedness, bankruptcy and failure to discharge certain judgments. If a default occurs and is not cured within any applicable cure period or is not waived, our obligations under the credit facility may be accelerated.

As of December 29, 2012, we were in compliance with all covenants under the revolving credit facility.

Letter of Credit Facility

On January 4, 2011, we entered into a revolving letter of credit facility with Bank of America, N.A. The credit facility is available to fund letters of credit on our behalf up to an aggregate outstanding amount of $5 million. We may terminate at any time, subject to proper notice, or from time to time permanently reduce the amount of the credit facility.

We pay a fee on outstanding letters of credit issued under the credit facility at a rate between LIBOR plus 1% and LIBOR plus 1.5% per annum, based on our ratio of indebtedness to Adjusted EBITDA. In addition, we pay a fee equal to 0.25% per annum of the actual daily amount by which the credit facility exceeds the aggregate undrawn amount of all outstanding letters of credit under the credit facility plus the aggregate of all unreimbursed drawings under all letters of credit under the credit facility. The maturity date for letters of credit issued under the credit facility must be no later than seven days prior to June 30, 2014.

As of December 29, 2012, we had letters of credit outstanding of $1.5 million under our revolving letter of credit facility. The credit facility contains customary terms and conditions for credit facilities of this type, including restrictions on our ability to incur or guaranty additional indebtedness, create liens, enter into transactions with affiliates, make loans or investments, sell assets, pay dividends or make distributions on, or repurchase, its stock, and consolidate or merge with other entities. In addition, we are required to meet certain financial covenants customary with this type of agreement, including maintaining a minimum specified consolidated net worth, a minimum ratio of indebtedness to Adjusted EBITDA and a minimum specified ratio of EBIT to interest expense.

The credit facility also contains customary events of default, including for payment defaults, breaches of representations, breaches of affirmative or negative covenants, cross defaults to other material indebtedness, bankruptcy, and failure to discharge certain judgments. If a default occurs and is not cured within any applicable cure period or is not waived, the lender may accelerate the obligations under the credit facility.

As of December 29, 2012, we were in compliance with all covenants under the revolving letter of credit facility.

Working Capital and Capital Expenditure Needs

We currently have no material cash commitments, except for normal recurring trade payables, expense accruals and operating leases, all of which we anticipate funding through working capital, funds provided by operating activities and our existing working capital line of credit. 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 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, the expansion 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. 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.

Contractual Obligations

We generally do not enter into binding purchase commitments. Our principal commitments consist of obligations under our working capital line of credit, leases for office space and minimum contractual obligations for services. The following table describes our commitments to settle contractual obligations in cash as of December 29, 2012:

Off-Balance Sheet Arrangements

As of December 29, 2012, we had no off-balance sheet arrangements as defined in Item 303(a)(4) of Regulation S-K.

Recently Issued Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board (“FASB”) issued amended guidance on fair value measurement and related disclosures. The new guidance clarifies the concepts applicable for fair value measurement of non-financial assets and requires the disclosure of quantitative information about the unobservable inputs used in a fair value measurement. This guidance will be effective for reporting periods beginning after December 15, 2011, and will be applied prospectively. This updated guidance did not have a material impact on our consolidated financial statements.

In June 2011, the FASB amended its accounting guidance on the presentation of other comprehensive income (OCI) in an entity’s financial statements. The amended guidance eliminates the option to present the components of OCI as part of the statement of changes in shareholders’ equity and provides two options for presenting OCI: in a statement included in the income statement or in a separate statement immediately following the income statement. The amendments do not change the guidance for the items that have to be reported in OCI or when an item of OCI has to be moved into net income. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. This updated guidance did not have a material impact on our consolidated financial statements.

In September 2011, the FASB issued updated guidance on the periodic testing of goodwill for impairment. The updated guidance gives companies the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The amendment is intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a qualitative assessment to determine whether

39

further impairment testing is necessary. The updated accounting guidance is effective for fiscal years beginning after December 15, 2011, with early adoption permitted. We elected to adopt the updated guidance in 2011. The adoption of this guidance did not impact our consolidated financial statements.

In February 2013, the FASB issued guidance requiring disclosure of amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present either on the face of the statement of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts not reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. This guidance is effective prospectively for the Company for annual and interim periods beginning January 1, 2013. The Company will comply with the disclosure requirements of this guidance for the quarter ending March 30, 2013.

From time to time, new accounting pronouncements are issued by FASB that are adopted by us as of the specified effective date. Unless otherwise discussed, we believe that the impact of recently issued standards, which are not yet effective, will not have a material impact on our consolidated financial statements upon adoption.

ITEM 7A.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Exchange Risk

We maintain sales and business operations in foreign countries. As such, we have exposure to adverse changes in exchange rates associated with operating expenses of our foreign operations, but we believe this exposure to be immaterial. Additionally, we accept orders for home robots products in currencies other than the U.S. dollar. We regularly monitor the level of non-U.S. dollar accounts receivable balances to determine if any actions, including possibly entering into foreign currency forward contracts, should be taken to minimize the impact of fluctuating exchange rates on our results of operations. Our international revenue is primarily denominated in U.S. dollars and therefore any fluctuations in the Euro or any other non-U.S. dollar currencies will have minimal direct impact on our international revenue. However, 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.

Interest Rate Sensitivity

At December 29, 2012, we had unrestricted cash and cash equivalents of $126.8 million and short term investments of $12.4 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 intend to maintain our portfolio of cash equivalents in a variety of securities, 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 29, 2012, all of our cash and cash equivalents were held in demand deposits and money market accounts.

Our exposure to market risk also relates to the increase or decrease in the amount of interest expense we must pay on any outstanding debt instruments, primarily certain borrowings under our working capital line of credit. The advances under the working capital line of credit bear a variable rate of interest determined as a function of the LIBOR rate at the time of the borrowing. At December 29, 2012, we had letters of credit outstanding of $1.5 million under our revolving letter of credit facility.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of

iRobot Corporation:

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, comprehensive income, stockholders' equity and cash flows present fairly, in all material respects, the financial position of iRobot Corporation and its subsidiariesat December 29, 2012and December 31, 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 29, 2012in 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 29, 2012, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on these financial statements and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. 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.

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.

As described in Item 9A, Controls and Procedures, management has excluded Evolution Robotics, Inc. from its assessment of internal control over financial reporting as of December 29, 2012 because it was acquired by the Company in a purchase business combination during 2012. We have also excluded Evolution Robotics, Inc. from our audit of internal control over financial reporting. Evolution Robotics, Inc. is a wholly-owned subsidiary whose total assets and total revenues represent 0.9% and 0.8%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 29, 2012.

iROBOT CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of the Business

iRobot Corporation (“iRobot” or the “Company”) develops robotics and artificial intelligence technologies and applies these technologies in producing and marketing robots. The majority of the Company’s revenue is generated from product sales and defense and security research and development contracts.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements include those of iRobot and its subsidiaries, after elimination of all intercompany accounts and transactions. In addition, certain prior year amounts have been reclassified to conform with the current year presentation. iRobot has prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America.

Use of Estimates

The preparation of these financial statements in conformity with accounting principles generally accepted in the United States requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates these estimates and judgments, including those related to revenue recognition, sales returns, bad debts, warranty claims, inventory reserves, valuation of investments, assumptions used in valuing stock-based compensation instruments and income taxes. The Company bases these estimates on historical and anticipated results, and trends and on various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results may differ from the Company’s estimates.

Fiscal Year-End

The Company operates and reports using a 52-53 week fiscal year ending on the Saturday closest to December 31. Accordingly, the Company’s fiscal quarters will end on the Saturday that falls closest to the last day of the third month of each quarter.

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 29, 2012 and December 31, 2011, cash equivalents were comprised of money market funds totaling $88.1 million and $117.2 million, respectively. These cash equivalents are carried at cost, which approximates fair value.

Short Term Investments

The Company’s investments are classified as available-for-sale and are recorded at fair value with any unrealized gain or loss recorded as an element of stockholders’ equity. The fair value of investments is determined based on quoted market prices at the reporting date for those instruments. As of December 29, 2012 and December 31, 2011, investments consisted of:

	December 29, 2012				December 31, 2011
	Cost		Fair Market Value		Cost		Fair Market Value
	(In thousands)
Corporate bonds	$	12,980	$	12,430	$	15,654	$	15,309
U.S. Government bond	—		—		2,500		2,502
Total short term investments	$	12,980	$	12,430	$	18,154	$	17,811

As of December 29, 2012, the Company’s investments had maturity dates ranging from January 2013 to November 2014.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Revenue Recognition

The Company derives its revenue from product sales, government research and development contracts, and commercial research and development contracts. The Company sells products directly to customers and indirectly through resellers and distributors. The Company recognizes revenue from sales of home robots under the terms of the customer agreement upon transfer of title and risk of loss to the customer, net of estimated returns, provided that collection is determined to be reasonably assured and no significant obligations remain. Sales to domestic resellers are typically subject to agreements allowing for limited rights of return, rebates and price protection. Accordingly, the Company reduces revenue for its estimates of liabilities for these rights of return at the time the related sale is recorded. The Company makes an estimate of sales returns for products sold by domestic resellers directly based on historical returns experience and other relevant data. The Company’s international distributor agreements do not currently allow for product returns and, as a result, no reserve for returns is established for this group of customers. The Company has aggregated and analyzed historical returns from domestic resellers and end users which form the basis of its estimate of future sales returns by resellers or end users. When a right of return exists, the provision for these estimated returns is recorded as a reduction of revenue at the time that the related revenue is recorded. If actual returns differ significantly from its estimates, such differences could have a material impact on the Company’s results of operations for the period in which the returns become known. The estimates for returns are adjusted periodically based upon historical rates of returns. The estimates and reserve for rebates and price protection are based on specific programs, expected usage and historical experience. Actual results could differ from these estimates.

Under cost-plus-fixed-fee (“CPFF”) type contracts, the Company recognizes revenue based on costs incurred plus a pro rata portion of the total fixed fee. Costs incurred include labor and material that are 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”). Annually, the Company submits 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 provisional rates currently in effect, 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 29, 2012, fiscal years 2007 through 2012 are open for audit by DCAA. In the situation where the Company’s anticipated actual billing rates will be lower than the provisional rates currently in effect, the Company records a cumulative revenue adjustment in the period in which the rate differential is identified. Revenue on firm fixed price (“FFP”) contracts is recognized using the percentage-of-completion method. For government product FFP contracts, revenue is recognized as the product is shipped or in accordance with the contract terms. Costs and estimated gross margins on contracts are recorded as revenue as work is performed based on the percentage that incurred costs compare to estimated total costs utilizing the most recent estimates of costs and funding. Changes in job performance, job conditions, and estimated profitability, including those arising from final contract settlements and government audits, may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Since many contracts extend over a long period of time, revisions in cost and funding estimates during the progress of work have the effect of adjusting earnings applicable to past performance in the current period. When the current contract estimate indicates a loss, a provision is made for the total anticipated loss in the current period. Revenue earned in excess of billings, if any, is recorded as unbilled revenue. Billings in excess of revenue earned, if any, are recorded as deferred revenue.

Allowance for Doubtful Accounts

The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivable that may not be collected. The allowance is based upon an assessment of customer creditworthiness, historical payment experience and the age of outstanding receivables.

(*) Deductions related to inventory reserve accounts represent amounts written off against the reserve.

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 equipment	3 years
Furniture	5
Machinery	2-5
Tooling	2-5
Business applications software	5-7
Capital leases and leasehold improvements	Term of lease

Expenditures for additions, renewals and betterments of plant 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.

Long-Lived Assets, including Purchased Intangible Assets

The Company periodically evaluates the recoverability of long-lived assets, including other purchased intangible 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.

50

iROBOT CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

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. There were no impairment charges recorded during any of the periods presented.

Goodwill

Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. The Company evaluates goodwill for impairment at the reporting unit level (operating segment or one level below an operating segment) annually or more frequently if the Company believes indicators of impairment exist. In accordance with the guidance, the Company is permitted to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then a two-step goodwill impairment test is performed.

The first step of the impairment test involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. If the carrying amount of a reporting unit exceeds the reporting unit's fair value, the Company performs the second step of the goodwill impairment test to determine the amount of impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit's goodwill with the carrying value of that goodwill.

Research and Development

Costs incurred in the research and development of the Company’s products, classified as cost of contract and research and development, are expensed as incurred.

Internal Use Software

The Company capitalizes costs associated with the development and implementation of software for internal use. At December 29, 2012 and December 31, 2011, the Company had $8.3 million and $8.3 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 $1.0 million, $0.9 million and $0.9 million of amortization expense for the years ended December 29, 2012, December 31, 2011 and January 1, 2011, respectively.

Concentration of Credit Risk and Significant Customers

Financial instruments which potentially expose the Company to concentrations of credit risk consist of accounts receivable. Management believes its credit policies are prudent and reflect normal industry terms and business risk. At December 29, 2012, three customers accounted for a total of 55% of the Company's accounts receivable balance, each of which was greater than 10% of the balance. Two of the customers accounting for 36% of the Company's accounts receivable balance secured their balance with guaranteed letters of credit. At December 31, 2011 four customers accounted for a total of 63% of the Company’s accounts receivable balance, each of which was greater than 10% of the balance. Two of the customers accounting for 29% of the Company’s accounts receivable balance secured their balance with guaranteed letters of credit. For the years ended December 29, 2012, December 31, 2011 and January 1, 2011, revenue from U.S. federal government orders, contracts and subcontracts, represented 15.1%, 36.1% and 38.4% of total revenue, respectively. For the fiscal years ended December 29, 2012 and December 31, 2011, the Company generated an aggregate of 30.6% and 23.6%, respectively, of total revenue from its home robots distributor in Japan and a network of affiliated European distributors of its home robots.

The Company maintains its cash in bank deposit accounts at high quality financial institutions. The individual balances, at times, may exceed federally insured limits.

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. Stock-based compensation cost for stock options is estimated at the grant date based on each option’s fair-value as calculated by the Black-Scholes option-pricing model. Stock-based compensation cost for restricted stock awards and restricted stock units is measured based on the closing fair market value of the Company’s common stock on the date of grant. The Company recognizes stock-based compensation cost as expense ratably on a straight-line basis over the requisite service period, net of estimated forfeitures.

Advertising Expense

The Company expenses advertising costs as they are incurred. During the years ended December 29, 2012, December 31, 2011 and January 1, 2011 advertising expense totaled $34.9 million, $20.4 million and $13.8 million, respectively.

Net Income Per Share

The following table presents the calculation of both basic and diluted net income per share:

	Fiscal Year Ended
	December 29, 2012		December 31, 2011		January 1, 2011
Net income	$	17,297	$	40,191	$	25,514
Weighted-average shares outstanding	27,577		26,712		25,394
Dilutive effect of employee stock options and restricted shares	724		1,212		1,074
Diluted weighted average shares outstanding	28,301		27,924		26,468
Basic income per share	$	0.63	$	1.50	$	1.00
Diluted income per share	$	0.61	$	1.44	$	0.96

Potentially dilutive securities representing approximately 0.8 million, 0.4 million and 1.0 million shares of common stock for the fiscal years ended December 29, 2012, December 31, 2011 and January 1, 2011, respectively, were excluded from the computation of diluted earnings per share for these periods because their effect would have been antidilutive.

Income Taxes

The Company is subject to taxation in the United States and various states and foreign jurisdictions. The statute of limitations for assessment by the IRS and state tax authorities is closed for fiscal years prior to December 31, 2008, although carryforward attributes that were generated prior to fiscal year 2008 may still be adjusted upon examination by the IRS or state tax authorities if they either have been or will be used in a future period. The IRS is currently examining the Company's tax returns for the years 2009 and 2010.

Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are provided if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

The Company monitors the realization of its deferred tax assets based on changes in circumstances, for example recurring periods of income for tax purposes following historical periods of cumulative losses or changes in tax laws or regulations. The Company's income tax provisions and its assessment of the ability to realize its deferred tax assets involve significant judgments and estimates.

In fiscal 2012, as part of the Company's acquisition accounting for the acquisition of Evolution Robotics, Inc., the Company recorded a valuation allowance of $2.7 million related to certain state tax attributes of Evolution Robotics, Inc. At December 29, 2012, the Company has total deferred tax assets of $30.6 million offset by a valuation allowance of $2.7 million.

Comprehensive Income

Accumulated other comprehensive income includes unrealized gains and losses on certain investments. The differences between net income and comprehensive income were related to unrealized gains (losses) on investments, net of tax.

Fair Value Measurements

The authoritative guidance for fair value establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The fair value of the Company’s bond investment is included in short term investments in its consolidated balance sheet.

Recent Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board (“FASB”) issued amended guidance on fair value measurement and related disclosures. The new guidance clarifies the concepts applicable for fair value measurement of non-financial assets and requires the disclosure of quantitative information about the unobservable inputs used in a fair value measurement. This guidance will be effective for reporting periods beginning after December 15, 2011, and will be applied prospectively. This updated guidance did not have a material impact on the Company's consolidated financial statements.

In June 2011, the FASB amended its accounting guidance on the presentation of other comprehensive income (OCI) in an entity’s financial statements. The amended guidance eliminates the option to present the components of OCI as part of the statement of changes in shareholders’ equity and provides two options for presenting OCI: in a statement included in the income statement or in a separate statement immediately following the income statement. The amendments do not change the guidance for the items that have to be reported in OCI or when an item of OCI has to be moved into net income. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. This updated guidance did not have a material impact on the Company's consolidated financial statements.

In September 2011, the FASB issued updated guidance on the periodic testing of goodwill for impairment. The updated guidance gives companies the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The amendment is intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a qualitative assessment to determine whether further impairment testing is necessary. The updated accounting guidance is effective for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company elected to adopt the updated guidance in 2011. The adoption of this guidance did not impact its consolidated financial statements.

53

iROBOT CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

In February 2013, the FASB issued guidance requiring disclosure of amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present either on the face of the statement of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts not reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. This guidance is effective prospectively for the Company for annual and interim periods beginning January 1, 2013. The Company will comply with the disclosure requirements of this guidance for the quarter ending March 30, 2013.

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 the impact of recently issued standards, which are not yet effective, will not have a material impact on its consolidated financial statements upon adoption.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

In November 2007, the Company recorded an investment of $2.5 million in a series of preferred stock of Advanced Scientific Concepts, Inc. In January 2012, the Company recorded an investment of $6.0 million in a series of preferred stock of InTouch Technologies, Inc. These investments are accounted for at cost. 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, 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. Since the Company believes the fair value of its investments is greater than the carrying value of its investments, it has not impaired these investments.

7. Revolving Line of Credit

The Company has an unsecured revolving credit facility with Bank of America, N.A., which is available to fund working capital and other corporate purposes. As of December 29, 2012, the total amount available for borrowing under its credit facility was $75.0 million and the full amount was available for borrowing. The interest on loans under the credit facility will accrue, at a rate between LIBOR plus 1% and LIBOR plus 1.5% based on the Company’s ratio of indebtedness to Adjusted EBITDA. The credit facility will terminate and all amounts outstanding thereunder will be due and payable in full on June 14, 2014.

As of December 29, 2012, the Company had no borrowings under its revolving credit facility. This credit facility contains customary terms and conditions for credit facilities of this type, including restrictions on the Company's ability to incur or guaranty additional indebtedness, create liens, enter into transactions with affiliates, make loans or investments, sell assets, pay dividends or make distributions on, or repurchase, the Company's stock, and consolidate or merge with other entities.

In addition, the Company is required to meet certain financial covenants customary with this type of agreement, including maintaining a minimum specified consolidated net worth, a minimum ratio of indebtedness to Adjusted EBITDA, and a minimum specified interest coverage ratio.

This credit facility contains customary events of default, including for payment defaults, breaches of representations, breaches of affirmative or negative covenants, cross defaults to other material indebtedness, bankruptcy and failure to discharge certain judgments. If a default occurs and is not cured within any applicable cure period or is not waived, the Company's obligations under the credit facility may be accelerated.

As of December 29, 2012, the Company was in compliance with all covenants under its credit facility.

8. Common Stock

Common stockholders are entitled to one vote for each share held and to receive dividends if and when declared by the Board of Directors and subject to and qualified by the rights of holders of the preferred stock. Upon dissolution or liquidation of the Company, holders of common stock will be entitled to receive all available assets subject to any preferential rights of any then outstanding preferred stock.

9. Stock Option Plans and Stock-Based Compensation

The Company has options outstanding under four stock incentive plans: the 1994 Stock Option Plan (the “1994 Plan”), the 2004 Stock Option and Incentive Plan (the “2004 Plan”), the 2005 Stock Option and Incentive Plan (the "2005 Plan") and the Evolution Robotics, Inc. 2007 Stock Plan (the "2007 Plan" and together with the 1994 Plan, the 2004 Plan and the 2005 Plan, the “Plans”). The 2005 Plan is the only one of the four plans under which new awards may currently be granted. Under the 2005 Plan, which became effective October 10, 2005, 1,583,682 shares were initially reserved for issuance in the form of incentive stock options, non-qualified stock options, stock appreciation rights, deferred stock awards and restricted stock awards. Additionally, the 2005 Plan provides that the number of shares reserved and available for issuance under the plan will automatically increase each January 1, beginning in 2007, by 4.5% of the outstanding number of shares of common stock on the immediately preceding December 31. Stock options returned to the Plans, with the exception of the 2007 Plan, as a result of their expiration, cancellation or termination are automatically made available for issuance under the 2005 Plan. Eligibility for incentive stock options is limited to those individuals whose employment status would qualify them for the tax treatment associated with incentive stock options in accordance with the Internal Revenue Code of 1986, as amended. As of December 29, 2012, there were 3,108,842 shares available for future grant under the 2005 Plan.

Options granted under the Plans are subject to terms and conditions as determined by the compensation committee of the board of directors, including vesting periods. Options granted under the Plans are exercisable in full at any time subsequent to vesting, generally vest over periods from zero to five years , and expire seven or ten years from the date of grant or, if earlier, 60 or 90 days from employee termination. The exercise price of incentive stock options is typically equal to the closing price on the NASDAQ Global Market on the date of grant. The exercise price of nonstatutory options may be set at a price other than the fair market value of the common stock.

In conjunction with the acquisition of Evolution Robotics, Inc. on October 1, 2012, each outstanding and unvested incentive stock option held by Evolution employees as of the acquisition date was automatically converted into stock options of the Company under the same terms and conditions as were applicable to the original Evolution grants. The number of replacement options granted and the associated exercise prices were determined utilizing a conversion ratio as defined in the merger agreement. There were 114,248 incentive stock options issued by the Company as a result of this automatic conversion with exercise prices ranging from $2.55 to $4.81. All of these options were granted from the 2007 Plan, which was assumed by the Company as a result of the acquisition.

The Company recognized $4.6 million of stock-based compensation expense during the fiscal year ended December 29, 2012 for stock options granted subsequent to the Company’s initial filing of its Form S-1 with the SEC. The unamortized fair value as of December 29, 2012 associated with these grants was $10.8 million with a weighted-average remaining recognition period of 2.54 years.

iROBOT CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The fair value of each option grant for the fiscal years ended December 29, 2012, December 31, 2011 and January 1, 2011 was computed on the grant date using the Black-Scholes option-pricing model with the following assumptions:

	Fiscal Year Ended	Fiscal Year Ended	Fiscal Year Ended
	December 29, 2012	December 31, 2011	January 1, 2011
Risk-free interest rate	0.63% — 0.90%	0.83% — 2.24%	1.27% — 2.28%
Expected dividend yield	—	—	—
Expected life	4.12 — 4.18 years	4.11 — 4.31 years	4.00 — 4.75 years
Expected volatility	63.0% — 64.0%	61.0% — 63.0%	57.0% — 62.0%

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. Prior to 2010, the expected term calculation was based upon the simplified method provided under the relevant authoritative guidance and was determined by averaging the contractual term of the stock option grants with the associated vesting term. In 2010, the Company determined that it had enough historical exercise experience and began to rely solely on company specific historical data for purposes of establishing expected term assumptions. Given the Company's initial public offering in November 2005 and the resulting short history as a public company, the Company could not rely solely on company specific historical data for purposes of establishing expected volatility. Consequently, prior to 2010, the Company performed an analysis that included company specific historical data combined with data of several peer companies with similar expected option lives to develop expected volatility assumptions. During 2010, the Company began to rely solely on company specific historical data for purposes of establishing expected volatility.

Based upon the above assumptions, the weighted average fair value of each stock option granted for the fiscal years ended December 29, 2012, December 31, 2011 and January 1, 2011 was $13.23, $16.55 and $8.24, respectively.

The table below summarizes stock option plan activity:

In certain jurisdictions, an insignificant provision has been made for deferred taxes on undistributed earnings of non-U.S. subsidiaries that the Company expects to distribute in 2013. In other jurisdictions, for the remaining undistributed earnings of non-U.S. subsidiaries, no provision has been made for deferred taxes as these earnings have been indefinitely reinvested. Determination of the amount of unrecognized deferred tax liability on these undistributed earnings is not practicable. As of December 29, 2012, a deferred tax liability has not been established for approximately $0.1 million of cumulative undistributed earnings of non-U.S. subsidiaries, as the Company plans to keep these amounts permanently reinvested overseas.

The net deferred tax assets as of December 29, 2012 and December 31, 2011 were $27.9 million and $21.5 million, respectively.

As of December 29, 2012, the Company has net operating loss carryforwards available to offset future federal and state taxes of $62.9 million, research and development credits carryforwards available to offset future federal and state taxes of $7.4 million and investment tax credit carryforwards to offset future state taxes of $0.6 million, which expire at various dates from 2013 to 2032. As of December 31, 2011, the Company had research and development credits carryforwards available to offset future state taxes of $4.4 million and investment tax credit carryforwards to offset future state taxes of $0.7 million, which expire at various dates from 2013 to 2026. Under the Internal Revenue Code, certain substantial changes in the Company’s ownership could result in an annual limitation on the amount of these tax carryforwards which can be utilized in future years. As of December 29, 2012, the Company has $62.9 million of net operating loss carryforwards and $1.8 million of federal and

state research and development credits related to the acquisition of Evolution Robotics that are limited by Section 382 and Section 383, respectively, of the Internal Revenue Code. However, these limitations do not cause any of these net operating loss carryforwards or federal and state research and development credits to expire unused.

The reconciliation of the expected tax (benefit) expense (computed by applying the federal statutory rate to income before income taxes) to actual tax expense was as follows:

	Fiscal Year Ended

The Company recognizes interest and penalties related to unrecognized tax benefits in its tax provision. As of December 29, 2012, December 31, 2011 and January 1, 2011, there were no material amounts related to accrued interest or penalties. We anticipate the settlement of federal tax audits may be finalized within the next twelve months and could result in a decrease in our unrecognized tax benefits of up to $2.9 million. If all of our unrecognized tax benefits as of December 29, 2012 were to become recognizable in the future, we would record a $3.9 million benefit to the income tax provision, reflective of federal benefit on state items.

We follow the with and without approach for direct and indirect effects of the windfall tax deductions.

11. Commitments and Contingencies

Legal

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 the Company's financial condition or results of operations.

Lease Obligations

The Company leases its facilities. Rental expense under operating leases for fiscal 2012, 2011 and 2010 amounted to $4.4 million, $4.1 million, and $3.7 million, respectively. Future minimum rental payments under operating leases were as follows as of December 29, 2012:

2013	$	3,158
2014	2,837
2015	2,820
2016	2,747
2017	2,505
Thereafter	5,682
Total minimum lease payments	$	19,749

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 with respect to the Company’s software. 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 29, 2012 and December 31, 2011, respectively.

Government Contract Contingencies

Several of the Company’s prime contracts with the U.S. federal government do 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 submits 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 29, 2012, fiscal years 2007 through 2012 are open for audit by DCAA.

Warranty

The Company provides warranties on most products and has established a reserve for warranty based on identified warranty costs. The reserve is included as part of accrued expenses (Note 6) in the accompanying consolidated balance sheets.

Activity related to the warranty accrual was as follows:

	Fiscal Year Ended
	December 29, 2012			December 31, 2011			January 1, 2011
	(In thousands)
Balance at beginning of period	$	10,306		$	9,284		$	6,105

Balance at end of period	$	6,057		$	10,306		$	9,284

 __________________________________

(*) During 2012, the Company recorded favorable adjustments relating to reductions in its international warranty accrual for our home robots business related to our sustained improvements in product quality, resulting in a net credit for its 2012 warranty provision.

(**) Warranty usage includes costs incurred for warranty obligations and the pro rata expiration of product warranties not utilized.

Sales Taxes

The Company collects and remits sales tax in jurisdictions in which it has a physical presence or it believes nexus exists, which therefore obligates the Company to collect and remit sales tax. The Company continually evaluates whether it has established a nexus in new jurisdictions with respect to sales tax. The Company has recorded a liability for potential exposure in several states where there is uncertainty about the point in time at which the Company established a sufficient business connection to create nexus. The Company continues to analyze possible sales tax exposure, but does not currently believe that any individual claim or aggregate claims that might arise will ultimately have a material effect on its consolidated results of operations, financial position or cash flows.

12. Employee Benefits

The Company sponsors a retirement plan under Section 401(k) of the Internal Revenue Code (the “Retirement Plan”). All Company employees, with the exception of temporary, contract and international employees are eligible to participate in the Retirement Plan after satisfying age and length of service requirements prescribed by the plan. Under the Retirement Plan, employees may make tax- deferred contributions, and the Company, at its sole discretion, and subject to the limits prescribed by the IRS, may make either a nonelective contribution on behalf of all eligible employees or a matching contribution on behalf of all plan participants.

The Company elected to make a matching contribution of approximately $1.7 million, $1.7 million and $1.5 million for the plan years ended December 29, 2012, December 31, 2011 and January 1, 2011 (“Plan-Year 2012,” “Plan-Year 2011” and “Plan-Year 2010”), respectively. The employer contribution represents a matching contribution at a rate of 50% of each employee’s first six percent contribution. Accordingly, each employee participating during Plan-Year 2012, Plan-Year 2011 and Plan-Year 2010 is entitled up to a maximum of three percent of his or her eligible annual payroll. The employer matching contribution for Plan-Year 2012 is included in accrued compensation.

13. Acquisition of Evolution Robotics, Inc.

On October 1, 2012, the Company acquired 100% of the equity of Evolution Robotics, Inc. (Evolution) for $74.8 million in cash, including the effect of working capital adjustments and cash received, with $8.88 million of the purchase price placed into an escrow account to settle certain claims for indemnification for breaches or inaccuracies in Evolution’s representations and warranties, covenants and agreements. Evolution is the developer of Mint and Mint Plus automatic floor cleaning robots, based in Pasadena, California, and is included in the Company's home robots business unit.

The assets and liabilities associated with Evolution were recorded at their fair values as of the acquisition date and the amounts are as follows:

	(In thousands)

iROBOT CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Intangible assets acquired totaling $27.0 million include completed technology of $26.9 million and a tradename of $0.1 million.

The completed technology consists of two separate assets, one valued at $17.9 million and one valued at $9.0 million. The estimated fair value attributed to $17.9 million of the completed technology was determined based upon a discounted cash flow forecast. Cash flows were discounted at a rate of 15.5%. The fair value of the $9.0 million relating to the second completed technology was determined based on the estimated cost to replace the technology. The fair value of the completed technology will be amortized over a period of 7-10 years on a straight-line basis, which approximates the pattern in which the economic benefits of the completed technology are expected to be realized.

The fair value of the tradename will be amortized over 3 years on a straight-line basis, which approximates the pattern in which the economic benefits of the tradename are expected to be realized.

Goodwill represents the excess of the purchase price over the fair values of the net tangible and intangible assets acquired and is primarily the result of expected synergies. None of the goodwill or identifiable intangibles associated with this transaction will be deductible for tax purposes.

Acquisition-related costs of $0.85 million were incurred in 2012.

Pro Forma Disclosures (Unaudited)

The following unaudited pro forma consolidated results of operations for fiscal 2012 and fiscal 2011 assume that the acquisition of Evolution occurred as of January 2, 2011.

	Fiscal Year Ended
	December 29, 2012		December 31, 2011
	(In thousands)
Revenue	$	445,469	$	482,850
Net Income	8,723		31,778

These pro forma amounts do not purport to be indicative of the results that would have actually been obtained if the acquisitions had occurred at the beginning of the periods presented or that may be obtained in the future.

Since the date of the acquisition, October 1, 2012, the Company has recorded $3.8 million of revenue attributable to Evolution within its consolidated financial statements.

14. Goodwill and other intangible assets

The carrying amount of the goodwill at December 29, 2012 is $49.0 million. $41.0 million resulted from the acquisition of Evolution Robotics, Inc. in October 2012, and $7.9 million resulted from the acquisition of Nekton completed in September 2008. In the fourth quarter of 2012, the Company completed its annual goodwill impairment test. The first step of the two-step impairment test, which involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill, was completed, and the Company did not identify any goodwill impairment.

Other intangible assets include the value assigned to completed technology, research contracts, and trade names. The estimated useful lives for all of these intangible assets are two to ten years. The intangible assets are being amortized on a straight-line basis, which is consistent with the pattern that the estimated economic benefits of the intangible assets are expected to be utilized.

During the fourth quarter of 2012, the Company identified certain immaterial errors to previously-reported product revenue and general and administrative expense and recorded out of period adjustments to correct for these items which resulted in a $0.3 million increase in fourth quarter 2012 net loss and a $0.1 million decrease in 2012 net income. These adjustments did not have a material impact on the reported financial position or results of operations for the year ended December 29, 2012. Additionally, had these adjustments been recorded in the prior periods to which they relate, the impact would not have been material to the reported financial position or results of operations for those periods.

18. Subsequent Event

In January 2013, the Company purchased an additional $2 million of preferred stock of InTouch Technologies, Inc. ("InTouch"), bringing its total investment in InTouch to $8 million. The total investment will be accounted utilizing the cost method of accounting since this investment is not in the form of common stock or in-substance common stock. The Company has concluded that it does not exert significant influence over InTouch since the Company does not have the right to appoint any members of the board of directors of InTouch and the Company’s investment as a percentage of the outstanding equity of InTouch is not significant. On a going forward basis, the Company will regularly monitor this investment to determine if facts and circumstances have changed in a manner that would require a change in accounting methodology.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

Not Applicable.

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”) and our Chief Financial Officer (“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. Management has excluded Evolution Robotics, Inc. from its assessment of internal control over financial reporting as of December 29, 2012 because it was acquired by the Company in a purchase business combination during 2012. We have also excluded Evolution Robotics, Inc. from our audit of internal control over financial reporting. Evolution Robotics, Inc. is a wholly-owned subsidiary whose total assets and total revenues represent 0.9% and 0.8%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 29, 2012. 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 29, 2012, based on criteria for effective internal control over financial reporting established in Internal Control — Integrated Framework, 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 29, 2012 based on the specified criteria.

The effectiveness of the Company’s internal control over financial reporting as of December 29, 2012 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Changes in Internal Control Over Financial Reporting

During the quarter ended December 29, 2012, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B.    OTHER INFORMATION

Our policy governing transactions in our securities by our directors, officers, and employees permits our officers, directors, funds affiliated with our directors, and certain other persons to enter into trading plans complying with Rule 10b5-l under the Securities Exchange Act of 1934, as amended. We have been advised that certain of our officers and directors (including Colin Angle, Chief Executive Officer, Glen Weinstein, Executive Vice President and Chief Legal Officer, and Alison Dean, Senior Vice President of Corporate Finance) of the Company have entered into trading plans (each a “Plan” and collectively, the “Plans”) covering periods after the date of this Annual Report on Form 10-K in accordance with Rule 10b5-l and our policy governing transactions in our securities. Generally, under these trading plans, the individual relinquishes control over the transactions once the trading plan is put into place. Accordingly, sales under these plans may occur at any time, including possibly before, simultaneously with, or immediately after significant events involving our company.

We anticipate that, as permitted by Rule 10b5-l and our policy governing transactions in our securities, some or all of our officers, directors and employees may establish trading plans in the future. We intend to disclose the names of our executive officers and directors who establish a trading plan in compliance with Rule 10b5-l and the requirements of our policy governing transactions in our securities in our future quarterly and annual reports on Form 10-Q and 10-K filed with the Securities and Exchange Commission. We, however, undertake no obligation to update or revise the information provided herein, including for revision or termination of an established trading plan, other than in such quarterly and annual reports.

Subsequent Event

18. Subsequent Event

In January 2013, the Company purchased an additional $2 million of preferred stock of InTouch Technologies, Inc. ("InTouch"), bringing its total investment in InTouch to $8 million. The total investment will be accounted utilizing the cost method of accounting since this investment is not in the form of common stock or in-substance common stock. The Company has concluded that it does not exert significant influence over InTouch since the Company does not have the right to appoint any members of the board of directors of InTouch and the Company’s investment as a percentage of the outstanding equity of InTouch is not significant. On a going forward basis, the Company will regularly monitor this investment to determine if facts and circumstances have changed in a manner that would require a change in accounting methodology.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements include those of iRobot and its subsidiaries, after elimination of all intercompany accounts and transactions. In addition, certain prior year amounts have been reclassified to conform with the current year presentation. iRobot has prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America.

Use of Estimates

The preparation of these financial statements in conformity with accounting principles generally accepted in the United States requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates these estimates and judgments, including those related to revenue recognition, sales returns, bad debts, warranty claims, inventory reserves, valuation of investments, assumptions used in valuing stock-based compensation instruments and income taxes. The Company bases these estimates on historical and anticipated results, and trends and on various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results may differ from the Company’s estimates.

Fiscal Year-End

The Company operates and reports using a 52-53 week fiscal year ending on the Saturday closest to December 31. Accordingly, the Company’s fiscal quarters will end on the Saturday that falls closest to the last day of the third month of each quarter.

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 29, 2012 and December 31, 2011, cash equivalents were comprised of money market funds totaling $88.1 million and $117.2 million, respectively. These cash equivalents are carried at cost, which approximates fair value.

Short Term Investments

The Company’s investments are classified as available-for-sale and are recorded at fair value with any unrealized gain or loss recorded as an element of stockholders’ equity. The fair value of investments is determined based on quoted market prices at the reporting date for those instruments. As of December 29, 2012 and December 31, 2011, investments consisted of:

	December 29, 2012				December 31, 2011
	Cost		Fair Market Value		Cost		Fair Market Value
	(In thousands)
Corporate bonds	$	12,980	$	12,430	$	15,654	$	15,309
U.S. Government bond	—		—		2,500		2,502
Total short term investments	$	12,980	$	12,430	$	18,154	$	17,811

As of December 29, 2012, the Company’s investments had maturity dates ranging from January 2013 to November 2014.

Revenue Recognition

The Company derives its revenue from product sales, government research and development contracts, and commercial research and development contracts. The Company sells products directly to customers and indirectly through resellers and distributors. The Company recognizes revenue from sales of home robots under the terms of the customer agreement upon transfer of title and risk of loss to the customer, net of estimated returns, provided that collection is determined to be reasonably assured and no significant obligations remain. Sales to domestic resellers are typically subject to agreements allowing for limited rights of return, rebates and price protection. Accordingly, the Company reduces revenue for its estimates of liabilities for these rights of return at the time the related sale is recorded. The Company makes an estimate of sales returns for products sold by domestic resellers directly based on historical returns experience and other relevant data. The Company’s international distributor agreements do not currently allow for product returns and, as a result, no reserve for returns is established for this group of customers. The Company has aggregated and analyzed historical returns from domestic resellers and end users which form the basis of its estimate of future sales returns by resellers or end users. When a right of return exists, the provision for these estimated returns is recorded as a reduction of revenue at the time that the related revenue is recorded. If actual returns differ significantly from its estimates, such differences could have a material impact on the Company’s results of operations for the period in which the returns become known. The estimates for returns are adjusted periodically based upon historical rates of returns. The estimates and reserve for rebates and price protection are based on specific programs, expected usage and historical experience. Actual results could differ from these estimates.

Under cost-plus-fixed-fee (“CPFF”) type contracts, the Company recognizes revenue based on costs incurred plus a pro rata portion of the total fixed fee. Costs incurred include labor and material that are 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”). Annually, the Company submits 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 provisional rates currently in effect, 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 29, 2012, fiscal years 2007 through 2012 are open for audit by DCAA. In the situation where the Company’s anticipated actual billing rates will be lower than the provisional rates currently in effect, the Company records a cumulative revenue adjustment in the period in which the rate differential is identified. Revenue on firm fixed price (“FFP”) contracts is recognized using the percentage-of-completion method. For government product FFP contracts, revenue is recognized as the product is shipped or in accordance with the contract terms. Costs and estimated gross margins on contracts are recorded as revenue as work is performed based on the percentage that incurred costs compare to estimated total costs utilizing the most recent estimates of costs and funding. Changes in job performance, job conditions, and estimated profitability, including those arising from final contract settlements and government audits, may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Since many contracts extend over a long period of time, revisions in cost and funding estimates during the progress of work have the effect of adjusting earnings applicable to past performance in the current period. When the current contract estimate indicates a loss, a provision is made for the total anticipated loss in the current period. Revenue earned in excess of billings, if any, is recorded as unbilled revenue. Billings in excess of revenue earned, if any, are recorded as deferred revenue.

Allowance for Doubtful Accounts

The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivable that may not be collected. The allowance is based upon an assessment of customer creditworthiness, historical payment experience and the age of outstanding receivables.

Activity related to the allowance for doubtful accounts was as follows:

	Fiscal Year Ended

_____________________  

(*) Deductions related to allowance for doubtful accounts represent amounts written off against the allowance, less recoveries.

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.

Activity related to the inventory reserve was as follows:

Balance at end of period	$	6,608		$	2,568		$	2,836

 ___________________________

(*) Deductions related to inventory reserve accounts represent amounts written off against the reserve.

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 equipment	3 years
Furniture	5
Machinery	2-5
Tooling	2-5
Business applications software	5-7
Capital leases and leasehold improvements	Term of lease

Expenditures for additions, renewals and betterments of plant 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.

Long-Lived Assets, including Purchased Intangible Assets

The Company periodically evaluates the recoverability of long-lived assets, including other purchased intangible 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. There were no impairment charges recorded during any of the periods presented.

Goodwill

Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. The Company evaluates goodwill for impairment at the reporting unit level (operating segment or one level below an operating segment) annually or more frequently if the Company believes indicators of impairment exist. In accordance with the guidance, the Company is permitted to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then a two-step goodwill impairment test is performed.

The first step of the impairment test involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. If the carrying amount of a reporting unit exceeds the reporting unit's fair value, the Company performs the second step of the goodwill impairment test to determine the amount of impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit's goodwill with the carrying value of that goodwill.

Research and Development

Costs incurred in the research and development of the Company’s products, classified as cost of contract and research and development, are expensed as incurred.

Internal Use Software

The Company capitalizes costs associated with the development and implementation of software for internal use. At December 29, 2012 and December 31, 2011, the Company had $8.3 million and $8.3 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 $1.0 million, $0.9 million and $0.9 million of amortization expense for the years ended December 29, 2012, December 31, 2011 and January 1, 2011, respectively.

Concentration of Credit Risk and Significant Customers

Financial instruments which potentially expose the Company to concentrations of credit risk consist of accounts receivable. Management believes its credit policies are prudent and reflect normal industry terms and business risk. At December 29, 2012, three customers accounted for a total of 55% of the Company's accounts receivable balance, each of which was greater than 10% of the balance. Two of the customers accounting for 36% of the Company's accounts receivable balance secured their balance with guaranteed letters of credit. At December 31, 2011 four customers accounted for a total of 63% of the Company’s accounts receivable balance, each of which was greater than 10% of the balance. Two of the customers accounting for 29% of the Company’s accounts receivable balance secured their balance with guaranteed letters of credit. For the years ended December 29, 2012, December 31, 2011 and January 1, 2011, revenue from U.S. federal government orders, contracts and subcontracts, represented 15.1%, 36.1% and 38.4% of total revenue, respectively. For the fiscal years ended December 29, 2012 and December 31, 2011, the Company generated an aggregate of 30.6% and 23.6%, respectively, of total revenue from its home robots distributor in Japan and a network of affiliated European distributors of its home robots.

The Company maintains its cash in bank deposit accounts at high quality financial institutions. The individual balances, at times, may exceed federally insured limits.

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. Stock-based compensation cost for stock options is estimated at the grant date based on each option’s fair-value as calculated by the Black-Scholes option-pricing model. Stock-based compensation cost for restricted stock awards and restricted stock units is measured based on the closing fair market value of the Company’s common stock on the date of grant. The Company recognizes stock-based compensation cost as expense ratably on a straight-line basis over the requisite service period, net of estimated forfeitures.

Advertising Expense

The Company expenses advertising costs as they are incurred. During the years ended December 29, 2012, December 31, 2011 and January 1, 2011 advertising expense totaled $34.9 million, $20.4 million and $13.8 million, respectively.

Net Income Per Share

The following table presents the calculation of both basic and diluted net income per share:

	Fiscal Year Ended
	December 29, 2012		December 31, 2011		January 1, 2011
Net income	$	17,297	$	40,191	$	25,514
Weighted-average shares outstanding	27,577		26,712		25,394
Dilutive effect of employee stock options and restricted shares	724		1,212		1,074
Diluted weighted average shares outstanding	28,301		27,924		26,468
Basic income per share	$	0.63	$	1.50	$	1.00
Diluted income per share	$	0.61	$	1.44	$	0.96

Potentially dilutive securities representing approximately 0.8 million, 0.4 million and 1.0 million shares of common stock for the fiscal years ended December 29, 2012, December 31, 2011 and January 1, 2011, respectively, were excluded from the computation of diluted earnings per share for these periods because their effect would have been antidilutive.

Income Taxes

The Company is subject to taxation in the United States and various states and foreign jurisdictions. The statute of limitations for assessment by the IRS and state tax authorities is closed for fiscal years prior to December 31, 2008, although carryforward attributes that were generated prior to fiscal year 2008 may still be adjusted upon examination by the IRS or state tax authorities if they either have been or will be used in a future period. The IRS is currently examining the Company's tax returns for the years 2009 and 2010.

Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are provided if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

The Company monitors the realization of its deferred tax assets based on changes in circumstances, for example recurring periods of income for tax purposes following historical periods of cumulative losses or changes in tax laws or regulations. The Company's income tax provisions and its assessment of the ability to realize its deferred tax assets involve significant judgments and estimates.

In fiscal 2012, as part of the Company's acquisition accounting for the acquisition of Evolution Robotics, Inc., the Company recorded a valuation allowance of $2.7 million related to certain state tax attributes of Evolution Robotics, Inc. At December 29, 2012, the Company has total deferred tax assets of $30.6 million offset by a valuation allowance of $2.7 million.

Comprehensive Income

Accumulated other comprehensive income includes unrealized gains and losses on certain investments. The differences between net income and comprehensive income were related to unrealized gains (losses) on investments, net of tax.

Fair Value Measurements

The authoritative guidance for fair value establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The Company’s assets measured at fair value on a recurring basis at December 29, 2012, were as follows:

	Fair Value Measurements as of
	December 29, 2012
Description	Level 1		Level 2		Level 3
	(In thousands)
Assets:
Money Market Funds	$	88,144	$	—	$	—
Corporate bonds	—		12,430		—
Total assets measured at fair value	$	88,144	$	12,430	$	—

The bond investments are valued based on observable market values as of the Company’s reporting date and are included in Level 2. The bond investments are recorded at fair value and marked-to-market at the end of each reporting period and realized and unrealized gains and losses are included in comprehensive income for that period. The fair value of the Company’s bond investments are included in short term investments in its consolidated balance sheet.

The Company’s assets measured at fair value on a recurring basis at December 31, 2011, were as follows:

	Fair Value Measurements as of
	December 31, 2011
Description	Level 1		Level 2		Level 3
	(In thousands)
Assets:
Money Market Funds	$	117,196	$	—	$	—

Corporate bonds	—		15,309		—
Total assets measured at fair value	$	117,196	$	17,811	$	—

The bond investments are valued based on observable market values as of the Company’s reporting date and is included in Level 2. The bond investment is recorded at fair value and marked-to-market at the end of each reporting period and realized and unrealized gains and losses are included in comprehensive income for that period. The fair value of the Company’s bond investment is included in short term investments in its consolidated balance sheet.

Recent Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board (“FASB”) issued amended guidance on fair value measurement and related disclosures. The new guidance clarifies the concepts applicable for fair value measurement of non-financial assets and requires the disclosure of quantitative information about the unobservable inputs used in a fair value measurement. This guidance will be effective for reporting periods beginning after December 15, 2011, and will be applied prospectively. This updated guidance did not have a material impact on the Company's consolidated financial statements.

In June 2011, the FASB amended its accounting guidance on the presentation of other comprehensive income (OCI) in an entity’s financial statements. The amended guidance eliminates the option to present the components of OCI as part of the statement of changes in shareholders’ equity and provides two options for presenting OCI: in a statement included in the income statement or in a separate statement immediately following the income statement. The amendments do not change the guidance for the items that have to be reported in OCI or when an item of OCI has to be moved into net income. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. This updated guidance did not have a material impact on the Company's consolidated financial statements.

In September 2011, the FASB issued updated guidance on the periodic testing of goodwill for impairment. The updated guidance gives companies the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The amendment is intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a qualitative assessment to determine whether further impairment testing is necessary. The updated accounting guidance is effective for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company elected to adopt the updated guidance in 2011. The adoption of this guidance did not impact its consolidated financial statements.

In February 2013, the FASB issued guidance requiring disclosure of amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present either on the face of the statement of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts not reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. This guidance is effective prospectively for the Company for annual and interim periods beginning January 1, 2013. The Company will comply with the disclosure requirements of this guidance for the quarter ending March 30, 2013.

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 the impact of recently issued standards, which are not yet effective, will not have a material impact on its consolidated financial statements upon adoption.

During the fourth quarter of 2012, the Company identified certain immaterial errors to previously-reported product revenue and general and administrative expense and recorded out of period adjustments to correct for these items which resulted in a $0.3 million increase in fourth quarter 2012 net loss and a $0.1 million decrease in 2012 net income. These adjustments did not have a material impact on the reported financial position or results of operations for the year ended December 29, 2012. Additionally, had these adjustments been recorded in the prior periods to which they relate, the impact would not have been material to the reported financial position or results of operations for those periods.

In certain jurisdictions, an insignificant provision has been made for deferred taxes on undistributed earnings of non-U.S. subsidiaries that the Company expects to distribute in 2013. In other jurisdictions, for the remaining undistributed earnings of non-U.S. subsidiaries, no provision has been made for deferred taxes as these earnings have been indefinitely reinvested. Determination of the amount of unrecognized deferred tax liability on these undistributed earnings is not practicable. As of December 29, 2012, a deferred tax liability has not been established for approximately $0.1 million of cumulative undistributed earnings of non-U.S. subsidiaries, as the Company plans to keep these amounts permanently reinvested overseas.

In fiscal 2012, as part of the Company's acquisition accounting for the acquisition of Evolution Robotics, Inc., the Company recorded a valuation allowance of $2.7 million related to certain state tax attributes of Evolution Robotics, Inc.

The table below summarizes activity relating to the valuation allowance:

Fiscal Year Ended	Balance at beginning  of period		Additions Charged to Costs and Expenses	Additions Charged to Goodwill	Deductions	Balance at End of Period
	(In thousands)

December 31, 2011	$	—	—	—	—	$	—
December 29, 2012	$	—	—	2,691	—	$	2,691

The net deferred tax assets as of December 29, 2012 and December 31, 2011 were $27.9 million and $21.5 million, respectively.

As of December 29, 2012, the Company has net operating loss carryforwards available to offset future federal and state taxes of $62.9 million, research and development credits carryforwards available to offset future federal and state taxes of $7.4 million and investment tax credit carryforwards to offset future state taxes of $0.6 million, which expire at various dates from 2013 to 2032. As of December 31, 2011, the Company had research and development credits carryforwards available to offset future state taxes of $4.4 million and investment tax credit carryforwards to offset future state taxes of $0.7 million, which expire at various dates from 2013 to 2026. Under the Internal Revenue Code, certain substantial changes in the Company’s ownership could result in an annual limitation on the amount of these tax carryforwards which can be utilized in future years. As of December 29, 2012, the Company has $62.9 million of net operating loss carryforwards and $1.8 million of federal and state research and development credits related to the acquisition of Evolution Robotics that are limited by Section 382 and Section 383, respectively, of the Internal Revenue Code. However, these limitations do not cause any of these net operating loss carryforwards or federal and state research and development credits to expire unused.

The reconciliation of the expected tax (benefit) expense (computed by applying the federal statutory rate to income before income taxes) to actual tax expense was as follows:

	Fiscal Year Ended
	December 29, 2012			December 31, 2011			January 1, 2011

A summary of the Company’s adjustments to its uncertain tax position is the current year is as follows:

	Fiscal Year Ended
	December 29, 2012
Balance at beginning of period	$	2,439
Increase for tax positions related to the current year	162
Increase for tax positions related to prior years	1,868
Decreases for settlements with applicable taxing authorities	—
Decreases for lapses of statute of limitations	—
Balance at end of period	$	4,469

The Company recognizes interest and penalties related to unrecognized tax benefits in its tax provision. As of December 29, 2012, December 31, 2011 and January 1, 2011, there were no material amounts related to accrued interest or penalties. We anticipate the settlement of federal tax audits may be finalized within the next twelve months and could result in a decrease in our unrecognized tax benefits of up to $2.9 million. If all of our unrecognized tax benefits as of December 29, 2012 were to become recognizable in the future, we would record a $3.9 million benefit to the income tax provision, reflective of federal benefit on state items.

We follow the with and without approach for direct and indirect effects of the windfall tax deductions.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

11. Commitments and Contingencies

Legal

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 the Company's financial condition or results of operations.

Lease Obligations

The Company leases its facilities. Rental expense under operating leases for fiscal 2012, 2011 and 2010 amounted to $4.4 million, $4.1 million, and $3.7 million, respectively. Future minimum rental payments under operating leases were as follows as of December 29, 2012:

	Operating Leases
2013	$	3,158
2014	2,837
2015	2,820
2016	2,747
2017	2,505
Thereafter	5,682
Total minimum lease payments	$	19,749

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 with respect to the Company’s software. 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 29, 2012 and December 31, 2011, respectively.

Government Contract Contingencies

Several of the Company’s prime contracts with the U.S. federal government do 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 submits 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 29, 2012, fiscal years 2007 through 2012 are open for audit by DCAA.

Warranty

The Company provides warranties on most products and has established a reserve for warranty based on identified warranty costs. The reserve is included as part of accrued expenses (Note 6) in the accompanying consolidated balance sheets.

Activity related to the warranty accrual was as follows:

	Fiscal Year Ended

Balance at end of period	$	6,057		$	10,306		$	9,284

 __________________________________

(*) During 2012, the Company recorded favorable adjustments relating to reductions in its international warranty accrual for our home robots business related to our sustained improvements in product quality, resulting in a net credit for its 2012 warranty provision.

(**) Warranty usage includes costs incurred for warranty obligations and the pro rata expiration of product warranties not utilized.

Sales Taxes

The Company collects and remits sales tax in jurisdictions in which it has a physical presence or it believes nexus exists, which therefore obligates the Company to collect and remit sales tax. The Company continually evaluates whether it has established a nexus in new jurisdictions with respect to sales tax. The Company has recorded a liability for potential exposure in several states where there is uncertainty about the point in time at which the Company established a sufficient business connection to create nexus. The Company continues to analyze possible sales tax exposure, but does not currently believe that any individual claim or aggregate claims that might arise will ultimately have a material effect on its consolidated results of operations, financial position or cash flows.

In November 2007, the Company recorded an investment of $2.5 million in a series of preferred stock of Advanced Scientific Concepts, Inc. In January 2012, the Company recorded an investment of $6.0 million in a series of preferred stock of InTouch Technologies, Inc. These investments are accounted for at cost. 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, 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. Since the Company believes the fair value of its investments is greater than the carrying value of its investments, it has not impaired these investments.

Stock Options Plans and Stock-Based Compensation

9. Stock Option Plans and Stock-Based Compensation

The Company has options outstanding under four stock incentive plans: the 1994 Stock Option Plan (the “1994 Plan”), the 2004 Stock Option and Incentive Plan (the “2004 Plan”), the 2005 Stock Option and Incentive Plan (the "2005 Plan") and the Evolution Robotics, Inc. 2007 Stock Plan (the "2007 Plan" and together with the 1994 Plan, the 2004 Plan and the 2005 Plan, the “Plans”). The 2005 Plan is the only one of the four plans under which new awards may currently be granted. Under the 2005 Plan, which became effective October 10, 2005, 1,583,682 shares were initially reserved for issuance in the form of incentive stock options, non-qualified stock options, stock appreciation rights, deferred stock awards and restricted stock awards. Additionally, the 2005 Plan provides that the number of shares reserved and available for issuance under the plan will automatically increase each January 1, beginning in 2007, by 4.5% of the outstanding number of shares of common stock on the immediately preceding December 31. Stock options returned to the Plans, with the exception of the 2007 Plan, as a result of their expiration, cancellation or termination are automatically made available for issuance under the 2005 Plan. Eligibility for incentive stock options is limited to those individuals whose employment status would qualify them for the tax treatment associated with incentive stock options in accordance with the Internal Revenue Code of 1986, as amended. As of December 29, 2012, there were 3,108,842 shares available for future grant under the 2005 Plan.

Options granted under the Plans are subject to terms and conditions as determined by the compensation committee of the board of directors, including vesting periods. Options granted under the Plans are exercisable in full at any time subsequent to vesting, generally vest over periods from zero to five years , and expire seven or ten years from the date of grant or, if earlier, 60 or 90 days from employee termination. The exercise price of incentive stock options is typically equal to the closing price on the NASDAQ Global Market on the date of grant. The exercise price of nonstatutory options may be set at a price other than the fair market value of the common stock.

In conjunction with the acquisition of Evolution Robotics, Inc. on October 1, 2012, each outstanding and unvested incentive stock option held by Evolution employees as of the acquisition date was automatically converted into stock options of the Company under the same terms and conditions as were applicable to the original Evolution grants. The number of replacement options granted and the associated exercise prices were determined utilizing a conversion ratio as defined in the merger agreement. There were 114,248 incentive stock options issued by the Company as a result of this automatic conversion with exercise prices ranging from $2.55 to $4.81. All of these options were granted from the 2007 Plan, which was assumed by the Company as a result of the acquisition.

The Company recognized $4.6 million of stock-based compensation expense during the fiscal year ended December 29, 2012 for stock options granted subsequent to the Company’s initial filing of its Form S-1 with the SEC. The unamortized fair value as of December 29, 2012 associated with these grants was $10.8 million with a weighted-average remaining recognition period of 2.54 years.

The fair value of each option grant for the fiscal years ended December 29, 2012, December 31, 2011 and January 1, 2011 was computed on the grant date using the Black-Scholes option-pricing model with the following assumptions:

	Fiscal Year Ended	Fiscal Year Ended	Fiscal Year Ended
	December 29, 2012	December 31, 2011	January 1, 2011
Risk-free interest rate	0.63% — 0.90%	0.83% — 2.24%	1.27% — 2.28%
Expected dividend yield	—	—	—
Expected life	4.12 — 4.18 years	4.11 — 4.31 years	4.00 — 4.75 years
Expected volatility	63.0% — 64.0%	61.0% — 63.0%	57.0% — 62.0%

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. Prior to 2010, the expected term calculation was based upon the simplified method provided under the relevant authoritative guidance and was determined by averaging the contractual term of the stock option grants with the associated vesting term. In 2010, the Company determined that it had enough historical exercise experience and began to rely solely on company specific historical data for purposes of establishing expected term assumptions. Given the Company's initial public offering in November 2005 and the resulting short history as a public company, the Company could not rely solely on company specific historical data for purposes of establishing expected volatility. Consequently, prior to 2010, the Company performed an analysis that included company specific historical data combined with data of several peer companies with similar expected option lives to develop expected volatility assumptions. During 2010, the Company began to rely solely on company specific historical data for purposes of establishing expected volatility.

Based upon the above assumptions, the weighted average fair value of each stock option granted for the fiscal years ended December 29, 2012, December 31, 2011 and January 1, 2011 was $13.23, $16.55 and $8.24, respectively.

The table below summarizes stock option plan activity:

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and other intangible assets

14. Goodwill and other intangible assets

The carrying amount of the goodwill at December 29, 2012 is $49.0 million. $41.0 million resulted from the acquisition of Evolution Robotics, Inc. in October 2012, and $7.9 million resulted from the acquisition of Nekton completed in September 2008. In the fourth quarter of 2012, the Company completed its annual goodwill impairment test. The first step of the two-step impairment test, which involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill, was completed, and the Company did not identify any goodwill impairment.

Other intangible assets include the value assigned to completed technology, research contracts, and trade names. The estimated useful lives for all of these intangible assets are two to ten years. The intangible assets are being amortized on a straight-line basis, which is consistent with the pattern that the estimated economic benefits of the intangible assets are expected to be utilized.

Intangible assets at December 29, 2012 and December 31, 2011 consisted of the following:

	December 29, 2012						December 31, 2011
	Cost		Accumulated Amortization		Net		Cost		Accumulated Amortization		Net

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 29, 2012

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying consolidated financial statements include those of iRobot and its subsidiaries, after elimination of all intercompany accounts and transactions. In addition, certain prior year amounts have been reclassified to conform with the current year presentation. iRobot has prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America.

Use of Estimates

Use of Estimates

The preparation of these financial statements in conformity with accounting principles generally accepted in the United States requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates these estimates and judgments, including those related to revenue recognition, sales returns, bad debts, warranty claims, inventory reserves, valuation of investments, assumptions used in valuing stock-based compensation instruments and income taxes. The Company bases these estimates on historical and anticipated results, and trends and on various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results may differ from the Company’s estimates.

Fiscal Year-End

Fiscal Year-End

The Company operates and reports using a 52-53 week fiscal year ending on the Saturday closest to December 31. Accordingly, the Company’s fiscal quarters will end on the Saturday that falls closest to the last day of the third month of each quarter.

Cash and Cash Equivalents

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 29, 2012 and December 31, 2011, cash equivalents were comprised of money market funds totaling $88.1 million and $117.2 million, respectively. These cash equivalents are carried at cost, which approximates fair value.

Short Term Investments

Short Term Investments

The Company’s investments are classified as available-for-sale and are recorded at fair value with any unrealized gain or loss recorded as an element of stockholders’ equity. The fair value of investments is determined based on quoted market prices at the reporting date for those instruments. As of December 29, 2012 and December 31, 2011, investments consisted of:

	December 29, 2012				December 31, 2011
	Cost		Fair Market Value		Cost		Fair Market Value
	(In thousands)
Corporate bonds	$	12,980	$	12,430	$	15,654	$	15,309
U.S. Government bond	—		—		2,500		2,502
Total short term investments	$	12,980	$	12,430	$	18,154	$	17,811

As of December 29, 2012, the Company’s investments had maturity dates ranging from January 2013 to November 2014.

Revenue Recognition

Revenue Recognition

The Company derives its revenue from product sales, government research and development contracts, and commercial research and development contracts. The Company sells products directly to customers and indirectly through resellers and distributors. The Company recognizes revenue from sales of home robots under the terms of the customer agreement upon transfer of title and risk of loss to the customer, net of estimated returns, provided that collection is determined to be reasonably assured and no significant obligations remain. Sales to domestic resellers are typically subject to agreements allowing for limited rights of return, rebates and price protection. Accordingly, the Company reduces revenue for its estimates of liabilities for these rights of return at the time the related sale is recorded. The Company makes an estimate of sales returns for products sold by domestic resellers directly based on historical returns experience and other relevant data. The Company’s international distributor agreements do not currently allow for product returns and, as a result, no reserve for returns is established for this group of customers. The Company has aggregated and analyzed historical returns from domestic resellers and end users which form the basis of its estimate of future sales returns by resellers or end users. When a right of return exists, the provision for these estimated returns is recorded as a reduction of revenue at the time that the related revenue is recorded. If actual returns differ significantly from its estimates, such differences could have a material impact on the Company’s results of operations for the period in which the returns become known. The estimates for returns are adjusted periodically based upon historical rates of returns. The estimates and reserve for rebates and price protection are based on specific programs, expected usage and historical experience. Actual results could differ from these estimates.

Under cost-plus-fixed-fee (“CPFF”) type contracts, the Company recognizes revenue based on costs incurred plus a pro rata portion of the total fixed fee. Costs incurred include labor and material that are 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”). Annually, the Company submits 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 provisional rates currently in effect, 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 29, 2012, fiscal years 2007 through 2012 are open for audit by DCAA. In the situation where the Company’s anticipated actual billing rates will be lower than the provisional rates currently in effect, the Company records a cumulative revenue adjustment in the period in which the rate differential is identified. Revenue on firm fixed price (“FFP”) contracts is recognized using the percentage-of-completion method. For government product FFP contracts, revenue is recognized as the product is shipped or in accordance with the contract terms. Costs and estimated gross margins on contracts are recorded as revenue as work is performed based on the percentage that incurred costs compare to estimated total costs utilizing the most recent estimates of costs and funding. Changes in job performance, job conditions, and estimated profitability, including those arising from final contract settlements and government audits, may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Since many contracts extend over a long period of time, revisions in cost and funding estimates during the progress of work have the effect of adjusting earnings applicable to past performance in the current period. When the current contract estimate indicates a loss, a provision is made for the total anticipated loss in the current period. Revenue earned in excess of billings, if any, is recorded as unbilled revenue. Billings in excess of revenue earned, if any, are recorded as deferred revenue.

Allowance for Doubtful Accounts

Allowance for Doubtful Accounts

The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivable that may not be collected. The allowance is based upon an assessment of customer creditworthiness, historical payment experience and the age of outstanding receivables.

Activity related to the allowance for doubtful accounts was as follows:

	Fiscal Year Ended
	December 29, 2012			December 31, 2011			January 1, 2011

(*) Deductions related to allowance for doubtful accounts represent amounts written off against the allowance, less recoveries.

Inventory

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.

Activity related to the inventory reserve was as follows:

	Fiscal Year Ended

Balance at end of period	$	6,608		$	2,568		$	2,836

 ___________________________

(*) Deductions related to inventory reserve accounts represent amounts written off against the reserve.

Property and Equipment

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 equipment	3 years
Furniture	5
Machinery	2-5
Tooling	2-5
Business applications software	5-7
Capital leases and leasehold improvements	Term of lease

Expenditures for additions, renewals and betterments of plant 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.

Long-Lived Assets, including Purchased Intangible Assets

Long-Lived Assets, including Purchased Intangible Assets

The Company periodically evaluates the recoverability of long-lived assets, including other purchased intangible 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. There were no impairment charges recorded during any of the periods presented.

Goodwill

Goodwill

Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. The Company evaluates goodwill for impairment at the reporting unit level (operating segment or one level below an operating segment) annually or more frequently if the Company believes indicators of impairment exist. In accordance with the guidance, the Company is permitted to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then a two-step goodwill impairment test is performed.

The first step of the impairment test involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. If the carrying amount of a reporting unit exceeds the reporting unit's fair value, the Company performs the second step of the goodwill impairment test to determine the amount of impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit's goodwill with the carrying value of that goodwill.

Research and Development

Research and Development

Costs incurred in the research and development of the Company’s products, classified as cost of contract and research and development, are expensed as incurred.

Internal Use Software

Internal Use Software

The Company capitalizes costs associated with the development and implementation of software for internal use. At December 29, 2012 and December 31, 2011, the Company had $8.3 million and $8.3 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 $1.0 million, $0.9 million and $0.9 million of amortization expense for the years ended December 29, 2012, December 31, 2011 and January 1, 2011, respectively.

Concentration of Credit Risk and Significant Customers

Concentration of Credit Risk and Significant Customers

Financial instruments which potentially expose the Company to concentrations of credit risk consist of accounts receivable. Management believes its credit policies are prudent and reflect normal industry terms and business risk. At December 29, 2012, three customers accounted for a total of 55% of the Company's accounts receivable balance, each of which was greater than 10% of the balance. Two of the customers accounting for 36% of the Company's accounts receivable balance secured their balance with guaranteed letters of credit. At December 31, 2011 four customers accounted for a total of 63% of the Company’s accounts receivable balance, each of which was greater than 10% of the balance. Two of the customers accounting for 29% of the Company’s accounts receivable balance secured their balance with guaranteed letters of credit. For the years ended December 29, 2012, December 31, 2011 and January 1, 2011, revenue from U.S. federal government orders, contracts and subcontracts, represented 15.1%, 36.1% and 38.4% of total revenue, respectively. For the fiscal years ended December 29, 2012 and December 31, 2011, the Company generated an aggregate of 30.6% and 23.6%, respectively, of total revenue from its home robots distributor in Japan and a network of affiliated European distributors of its home robots.

Stock-Based Compensation

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. Stock-based compensation cost for stock options is estimated at the grant date based on each option’s fair-value as calculated by the Black-Scholes option-pricing model. Stock-based compensation cost for restricted stock awards and restricted stock units is measured based on the closing fair market value of the Company’s common stock on the date of grant. The Company recognizes stock-based compensation cost as expense ratably on a straight-line basis over the requisite service period, net of estimated forfeitures.

Advertising Expense

Advertising Expense

The Company expenses advertising costs as they are incurred. During the years ended December 29, 2012, December 31, 2011 and January 1, 2011 advertising expense totaled $34.9 million, $20.4 million and $13.8 million, respectively.

Net Income Per Share

Net Income Per Share

The following table presents the calculation of both basic and diluted net income per share:

	Fiscal Year Ended
	December 29, 2012		December 31, 2011		January 1, 2011
Net income	$	17,297	$	40,191	$	25,514
Weighted-average shares outstanding	27,577		26,712		25,394
Dilutive effect of employee stock options and restricted shares	724		1,212		1,074
Diluted weighted average shares outstanding	28,301		27,924		26,468
Basic income per share	$	0.63	$	1.50	$	1.00
Diluted income per share	$	0.61	$	1.44	$	0.96

Potentially dilutive securities representing approximately 0.8 million, 0.4 million and 1.0 million shares of common stock for the fiscal years ended December 29, 2012, December 31, 2011 and January 1, 2011, respectively, were excluded from the computation of diluted earnings per share for these periods because their effect would have been antidilutive.

Income Taxes

Income Taxes

The Company is subject to taxation in the United States and various states and foreign jurisdictions. The statute of limitations for assessment by the IRS and state tax authorities is closed for fiscal years prior to December 31, 2008, although carryforward attributes that were generated prior to fiscal year 2008 may still be adjusted upon examination by the IRS or state tax authorities if they either have been or will be used in a future period. The IRS is currently examining the Company's tax returns for the years 2009 and 2010.

Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are provided if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

The Company monitors the realization of its deferred tax assets based on changes in circumstances, for example recurring periods of income for tax purposes following historical periods of cumulative losses or changes in tax laws or regulations. The Company's income tax provisions and its assessment of the ability to realize its deferred tax assets involve significant judgments and estimates.

In fiscal 2012, as part of the Company's acquisition accounting for the acquisition of Evolution Robotics, Inc., the Company recorded a valuation allowance of $2.7 million related to certain state tax attributes of Evolution Robotics, Inc. At December 29, 2012, the Company has total deferred tax assets of $30.6 million offset by a valuation allowance of $2.7 million.

Comprehensive Income

Comprehensive Income

Accumulated other comprehensive income includes unrealized gains and losses on certain investments. The differences between net income and comprehensive income were related to unrealized gains (losses) on investments, net of tax.

Fair Value Measurements

Fair Value Measurements

The authoritative guidance for fair value establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The Company’s assets measured at fair value on a recurring basis at December 29, 2012, were as follows:

	Fair Value Measurements as of
	December 29, 2012
Description	Level 1		Level 2		Level 3
	(In thousands)
Assets:
Money Market Funds	$	88,144	$	—	$	—
Corporate bonds	—		12,430		—
Total assets measured at fair value	$	88,144	$	12,430	$	—

The bond investments are valued based on observable market values as of the Company’s reporting date and are included in Level 2. The bond investments are recorded at fair value and marked-to-market at the end of each reporting period and realized and unrealized gains and losses are included in comprehensive income for that period. The fair value of the Company’s bond investments are included in short term investments in its consolidated balance sheet.

The Company’s assets measured at fair value on a recurring basis at December 31, 2011, were as follows:

	Fair Value Measurements as of
	December 31, 2011
Description	Level 1		Level 2		Level 3

Total assets measured at fair value	$	117,196	$	17,811	$	—

The bond investments are valued based on observable market values as of the Company’s reporting date and is included in Level 2. The bond investment is recorded at fair value and marked-to-market at the end of each reporting period and realized and unrealized gains and losses are included in comprehensive income for that period. The fair value of the Company’s bond investment is included in short term investments in its consolidated balance sheet.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board (“FASB”) issued amended guidance on fair value measurement and related disclosures. The new guidance clarifies the concepts applicable for fair value measurement of non-financial assets and requires the disclosure of quantitative information about the unobservable inputs used in a fair value measurement. This guidance will be effective for reporting periods beginning after December 15, 2011, and will be applied prospectively. This updated guidance did not have a material impact on the Company's consolidated financial statements.

In June 2011, the FASB amended its accounting guidance on the presentation of other comprehensive income (OCI) in an entity’s financial statements. The amended guidance eliminates the option to present the components of OCI as part of the statement of changes in shareholders’ equity and provides two options for presenting OCI: in a statement included in the income statement or in a separate statement immediately following the income statement. The amendments do not change the guidance for the items that have to be reported in OCI or when an item of OCI has to be moved into net income. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. This updated guidance did not have a material impact on the Company's consolidated financial statements.

In September 2011, the FASB issued updated guidance on the periodic testing of goodwill for impairment. The updated guidance gives companies the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The amendment is intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a qualitative assessment to determine whether further impairment testing is necessary. The updated accounting guidance is effective for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company elected to adopt the updated guidance in 2011. The adoption of this guidance did not impact its consolidated financial statements.

In February 2013, the FASB issued guidance requiring disclosure of amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present either on the face of the statement of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts not reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. This guidance is effective prospectively for the Company for annual and interim periods beginning January 1, 2013. The Company will comply with the disclosure requirements of this guidance for the quarter ending March 30, 2013.

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 the impact of recently issued standards, which are not yet effective, will not have a material impact on its consolidated financial statements upon adoption.

Acquisition of Evolution Robotics, Inc.

12 Months Ended

Dec. 29, 2012

Business Combinations [Abstract]

Acquisition of Evolution Robotics, Inc.

13. Acquisition of Evolution Robotics, Inc.

On October 1, 2012, the Company acquired 100% of the equity of Evolution Robotics, Inc. (Evolution) for $74.8 million in cash, including the effect of working capital adjustments and cash received, with $8.88 million of the purchase price placed into an escrow account to settle certain claims for indemnification for breaches or inaccuracies in Evolution’s representations and warranties, covenants and agreements. Evolution is the developer of Mint and Mint Plus automatic floor cleaning robots, based in Pasadena, California, and is included in the Company's home robots business unit.

The assets and liabilities associated with Evolution were recorded at their fair values as of the acquisition date and the amounts are as follows:

	(In thousands)
Cash and cash equivalents	$	356
Accounts receivable	1,635
Inventory	5,069
Other current assets	770
Deferred tax asset	1,740
Fixed assets	384
Goodwill	41,041
Intangible assets	27,000
Total Assets	77,995
Accounts payable	(2,793		)
Accrued expenses	(51		)
Accrued compensation	(91		)
Other liabilities	(174		)
Total consideration transferred	$	74,886

Intangible assets acquired totaling $27.0 million include completed technology of $26.9 million and a tradename of $0.1 million.

The completed technology consists of two separate assets, one valued at $17.9 million and one valued at $9.0 million. The estimated fair value attributed to $17.9 million of the completed technology was determined based upon a discounted cash flow forecast. Cash flows were discounted at a rate of 15.5%. The fair value of the $9.0 million relating to the second completed technology was determined based on the estimated cost to replace the technology. The fair value of the completed technology will be amortized over a period of 7-10 years on a straight-line basis, which approximates the pattern in which the economic benefits of the completed technology are expected to be realized.

The fair value of the tradename will be amortized over 3 years on a straight-line basis, which approximates the pattern in which the economic benefits of the tradename are expected to be realized.

Goodwill represents the excess of the purchase price over the fair values of the net tangible and intangible assets acquired and is primarily the result of expected synergies. None of the goodwill or identifiable intangibles associated with this transaction will be deductible for tax purposes.

Acquisition-related costs of $0.85 million were incurred in 2012.

Pro Forma Disclosures (Unaudited)

The following unaudited pro forma consolidated results of operations for fiscal 2012 and fiscal 2011 assume that the acquisition of Evolution occurred as of January 2, 2011.

	Fiscal Year Ended
	December 29, 2012		December 31, 2011
	(In thousands)
Revenue	$	445,469	$	482,850
Net Income	8,723		31,778

These pro forma amounts do not purport to be indicative of the results that would have actually been obtained if the acquisitions had occurred at the beginning of the periods presented or that may be obtained in the future.

Since the date of the acquisition, October 1, 2012, the Company has recorded $3.8 million of revenue attributable to Evolution within its consolidated financial statements.
