Notes To Consolidated Financial Statements

(unaudited)

1. Description of 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 government and commercial 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. iRobot has prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America.

The accompanying unaudited financial data as of March 30, 2013 and for the three months ended March 30, 2013 and March 31, 2012 has been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. The year-end balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto included in its Annual Report on Form 10-K for the fiscal year ended December 29, 2012, filed with the SEC on February 15, 2013.

In the opinion of management, all adjustments necessary to state fairly its statement of financial position as of March 30, 2013 and results of operations and cash flows for the periods ended March 30, 2013 and March 31, 2012 have been made. The results of operations and cash flows for any interim period are not necessarily indicative of the operating results and cash flows for the full fiscal year or any future periods.

Reorganization

In fiscal year 2012, the Company initiated a reorganization that resulted in, among other things, the centralization of all of the Company's engineering and operations activities. This reorganization was completed at the beginning of fiscal year 2013. In conjunction with this reorganization, the Company reviewed the financial statement classification of its costs and expenses. As a result of this review, the Company decided to classify certain expenses differently than had been classified and presented in prior periods to provide a more clear understanding of the Company's financial performance. As part of this review, the Company also evaluated the impact of the reorganization on its segment reporting and determined that certain modifications were necessary to present the segment information as now viewed by the Company's chief operating decision maker. Although the classification of certain expenses on the income statement has changed in fiscal year 2013 as compared to prior periods, the Company recast the financial results of prior periods in a manner consistent with the fiscal year 2013 presentation for comparability purposes. The reclassified amounts reflected in the consolidated statement of income for the three months ended March 31, 2012 included herein conform to the fiscal year 2013 presentation. This reclassification of costs and expenses did not impact previously reported net income or earnings per share as the changes only impacted the categorization of costs within the consolidated statements of income for the periods in question. Consequently, the classification changes did not impact previously presented consolidated balance sheets, statements of cash flow or statements of stockholders' equity.

Revision of Consolidated Balance Sheet as of December 29, 2012

During the three month period ended March 30, 2013, the Company identified a classification error related to its reserves for uncertain tax positions on its December 29, 2012 consolidated balance sheet. The Company had recorded a gross income tax receivable in current assets and a gross uncertain tax positions liability against that receivable in current liabilities as of December 29, 2012. In addition, the Company misclassified certain uncertain tax position liabilities in current and long-term liabilities. The impact of the errors on the December 29, 2012 consolidated balance sheet was a decrease in Other Current Assets of $2.7 million, an increase in Other Assets of $0.2 million, a decrease in Accrued Expenses of $2.9 million, and an increase in Long-term Liabilities of $0.4 million. These adjustments were not considered to be material individually or in the aggregate to previously issued financial statements. The Company has revised its December 29, 2012 consolidated balance sheet to correct these errors as reflected herein. This revision had no impact on the consolidated statement of income, the

consolidated statement of comprehensive income, or total cash flows from operating activities, total cash flows from investing activities, or total cash flows from financing activities.

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 end on the Saturday that falls closest to the last day of the third month of each quarter.

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 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 of home robots 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 March 30, 2013, 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

8

iROBOT CORPORATION

Notes to Consolidated Financial Statements - (Continued)

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.

Accounting for Share-Based Payments

The Company accounts for share-based payments to employees, including grants of employee stock options and awards in the form of restricted shares and restricted stock units by establishing the fair value of each option grant using the Black-Scholes option- pricing model and the fair value of awards based on stock price at the time of grant. The fair value of share-based payments is recorded by the Company as a charge against earnings. The Company recognizes share-based payment expense over the requisite service period of the underlying grants and awards. The Company’s share-based payment awards are accounted for as equity instruments.

Net Income Per Share

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

	Three Months Ended
	March 30, 2013		March 31, 2012
Net income	$	8,355	$	653
Weighted-average shares outstanding	27,930		27,352
Dilutive effect of employee stock options and restricted shares	628		931
Diluted weighted-average shares outstanding	28,558		28,283
Basic income per share	$	0.30	$	0.02
Diluted income per share	$	0.29	$	0.02

Restricted stock units and options to acquire representing approximately 1.1 million and 0.5 million shares of common stock for the three month periods ended March 30, 2013 and March 31, 2012, 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 examination by the Internal Revenue Service (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 2009 may still be adjusted upon examination by the IRS or state tax authorities if they either have been or will be used in a period for which the statute of limitations is still open. The IRS is currently examining the Company’s tax returns for the years 2008, 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.

The Company recorded a tax provision of $0.5 million and $0.2 million for the three month periods ended March 30, 2013 and March 31, 2012, respectively. The $0.5 million provision for the three month period ended March 30, 2013 resulted in an effective income tax rate of 5.8%. The $0.2 million provision for the three month period ended March 31, 2012 resulted in an effective income tax rate of 27.2%. In January 2013, legislation was enacted that included the extension of federal research and development tax credits. The legislation retroactively reinstated research and development tax credits for 2012 and extended them through December 31, 2013. As a result, the Company recorded a discrete benefit related to 2012 during the three month period ended March 30, 2013. The decrease in the effective income tax rate from 27.2% for the three month period ended March 31, 2012 to 5.8% for the three month period ended March 30, 2103 was primarily due to the extension of federal research and development tax credits in 2013.

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 March 30, 2013, were as follows:

	Fair Value Measurements as of March 30, 2013
	Level 1		Level 2		Level 3
	(In thousands)
Description
Assets:
Money market funds	$	86,774	$	—	$	—
Corporate bonds	—		13,869		—
Total assets measured at fair value	$	86,774	$	13,869	$	—

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
	Level 1		Level 2		Level 3
	(In thousands)
Description
Assets:
Money market funds	$	88,144	$	—	$	—
Corporate bonds	—		12,430		—
Total assets measured at fair value	$	88,144	$	12,430	$	—

In each table above, 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. The 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.

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. The Company first assesses 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.

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board ("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 impact of these amendments on the Company’s consolidated financial statements was not material.

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

4. Stock Option Plans

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 those issued under 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 March 30, 2013, there were 3,855,966 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 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.

On March 8, 2013, the Company granted to certain employees, including executive officers, an annual merit grant of stock options totaling 181,300 shares of the Company’s common stock and 331,725 restricted stock units. Additionally, an employee was granted 60,000 stock options and 30,000 restricted stock units in connection with the commencement of his employment. Each of the above stock options have a per share exercise price of $22.86, the closing price of the Company’s common stock on NASDAQ on March 8, 2013. The stock options and restricted stock units generally vest over a four year period.

Lease Obligations

Rental expense under operating leases for the three months ended March 30, 2013 and March 31, 2012 were $1.0 million and $1.1 million, respectively. Future minimum rental payments under operating leases were as follows as of March 30, 2013:

	Operating Leases
	(In thousands)
Remainder of 2013	$	2,353

2015	2,820
2016	2,747
2017	2,505
Thereafter	5,683
Total minimum lease payments	$	18,945

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.

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 products. The term of these indemnification agreements is generally perpetual 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 March 30, 2013 and December 29, 2012, respectively.

(1) Warranty usage includes the expiration of product warranties unutilized.

Inventory

Based upon its business outlook, the Company provides purchase orders and material authorizations to its contract manufacturers for future delivery of finished goods. On the basis of these purchase orders and material authorizations, the Company’s contract manufacturers order components from their respective suppliers. Should the Company’s business outlook not materialize as expected, it may be contractually obligated to purchase from the contract manufacturers inventory they have secured on behalf of the Company, which may be in excess of customer demand. The Company continually evaluates whether any such obligation or exposure exists and records a liability in the period in which such obligations or exposure are identified.

7. 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.

Pro Forma Disclosures (Unaudited)

The following unaudited pro forma consolidated results of operations for the three month periods ended March 30, 2013 and March 31, 2012 assume that the acquisition of Evolution occurred as of January 1, 2012.

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.

8. Industry Segment, Geographic Information and Significant Customers

The Company operates in two reportable segments, the home robots business unit and the defense and security robots business unit. The nature of products and types of customers for the two segments vary significantly. As such, the segments are managed separately. As a result of the reorganization completed at the beginning of fiscal year 2013, the Company determined that certain modifications were necessary to present the segment information as now viewed by the Company's chief operating decision maker. While no new reportable segments resulted from the reorganization, certain revenue and expenses previously included in the home robots business unit and the defense and security robots business unit are now combined with other revenue and expenses and presented separately from the two reportable segments.

Home Robots

The Company’s home robots business unit offers products to consumers through a network of retail businesses throughout the United States, to various countries through international distributors and retailers, and through the Company’s on-line store. The Company’s home robots business unit includes mobile robots used in the maintenance of households.

Defense and Security

The Company’s defense and security robots business unit offers products through a small U.S. government-focused sales force. Products are also sold to a limited number of countries, other than the United States, primarily through international distributors but also through a small internationally focused sales team. The Company’s defense and security robots are used by various U.S. and foreign governments, primarily for reconnaissance and bomb disposal missions.

Other

The Company’s other revenue and cost of revenue result from other, smaller business units that do not meet the criteria of a reportable segment, as well as certain operational costs included in cost of revenue.

The table below presents segment information about revenue, cost of revenue, gross margin and income before income taxes:

Notes to Consolidated Financial Statements - (Continued)

For the three months ended March 30, 2013, the Company generated 21.9% and 10.2%, respectively, of total revenue from two of its international distributors of home robots products. For the three months ended March 31, 2012, the Company generated 21.0% and 12.3%, respectively, of total revenue from two of its international distributors of home robot products.

9. Goodwill, Other Intangible Assets and Other Assets

Goodwill

The carrying amount of the Company's goodwill at March 30, 2013 is $49.0 million, of which $41.1 million resulted from the acquisition of Evolution Robotics, Inc. in October 2012 and was assigned to the home robots reporting unit. $7.9 million resulted from the acquisition of Nekton Research, LLC completed in September 2008 and was assigned to the defense and security reporting unit. In conjunction with the reorganization completed as of the beginning of the fiscal year 2013, the defense and security reporting unit was divided into two reporting units: the defense and security reporting unit and the research reporting unit. As a result, the goodwill of $7.9 million was reassigned utilizing a relative fair value allocation approach. $7.7 million and $0.2 million were reassigned to the defense and security and research reporting units, respectively. Further, the Company completed an interim impairment test for each reporting unit and did not identify any impairment.

Other Intangible Assets

Other intangible assets include the value assigned to completed technology, research contracts, and a trade name. 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 economic benefits of the intangible assets are expected to be utilized.

Intangible assets at March 30, 2013 and December 29, 2012 consisted of the following:

	March 30, 2013						December 29, 2012
	Cost		Accumulated Amortization		Net		Cost		Accumulated Amortization		Net
	(In thousands)
Completed technology	$	30,600	$	3,424	$	27,176	$	30,600	$	2,468	$	28,132

Total	$	31,500	$	4,241	$	27,259	$	31,500	$	3,276	$	28,224

Amortization expense related to acquired intangible assets was $965,000 and $93,000 for the three months ended March 30, 2013 and March 31, 2012, respectively. The estimated future amortization expense is expected to be as follows:

	(In thousands)
Remainder of 2013	$	2,895
2014	3,861
2015	3,852
2016	3,827
2017	3,827
Thereafter	8,997
Total	$	27,259

Other Assets

In January 2013, the Company recorded an additional investment of $2.0 million of preferred stock of InTouch Technologies, Inc. (“InTouch”), bringing its total investment to $8.0 million of preferred stock of InTouch. The total investment is 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

Notes to Consolidated Financial Statements - (Continued)

of the outstanding equity of InTouch is not significant. On a going forward basis, the Company will continue to monitor this investment to determine if facts and circumstances have changed in a manner that would require a change in accounting methodology. Additionally, the Company will continue to regularly evaluate whether or not this investment has been impaired by considering such factors as economic environment, market conditions, operational performance and other specific factors relating to the business underlying the investment. If any such impairment is identified, a reduction in the carrying value of the investment would be recorded at that time.

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 Braava, our iRobot-branded version of the 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 March 30, 2013, we had 531 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.

During the three month period ended March 30, 2013, domestic revenue growth of 44% drove a 14% increase in home robots revenue as compared to the three month period ended March 31, 2012. This increase resulted primarily from our domestic advertising campaign, strong sell through across our domestic retailers during the three month period ended December 29, 2012, and expanded distribution of the Roomba 600 and 700 series robots. Offsetting this increase was a decrease in our defense and security business unit revenue of 22% as compared to the three month period ended March 31, 2012 due to program cancellations and ongoing budget reductions within the U.S. government. We also shipped the first RP-

17

VITA units during the three month period ended March 30, 2013. RP-VITA (Remote Presence Virtual + Independent Telemedicine Assistant), which was jointly developed with InTouch Technologies, Inc., is the first autonomous navigation remote presence robot to receive U.S. Food and Drug Administration clearance for use in hospitals.

In fiscal year 2012, we initiated a reorganization that resulted in, among other things, the centralization of all of our engineering and operations activities. This reorganization was completed at the beginning of fiscal year 2013. In conjunction with this reorganization, we reviewed the financial statement classification of our costs and expenses. As a result of this review, we decided to classify certain expenses differently than had been classified and presented in prior periods to provide a more clear understanding of our financial performance. As part of this review, we also evaluated the impact of the reorganization on our segment reporting and determined that certain modifications were necessary to present the segment information as now viewed by our chief operating decision maker. Although the classification of certain expenses on the income statement has changed in fiscal year 2013 as compared to prior periods, we recast the financial results of prior periods in a manner consistent with the fiscal year 2013 presentation for comparability purposes. The reclassified amounts reflected in the consolidated statement of income for the three months ended March 31, 2012 included herein conform to the fiscal year 2013 presentation. This reclassification of costs and expenses did not impact previously reported net income or earnings per share as the changes only impacted the categorization of costs within the consolidated statements of income for the periods in question. Consequently, the classification changes did not impact previously presented consolidated balance sheets, statements of cash flow or statements of stockholders' equity.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and judgments, in particular those related to revenue recognition (specifically sales returns and other allowances); valuation allowances; assumptions used in valuing stock-based compensation instruments; evaluating loss contingencies; and valuation allowances for deferred tax assets. Actual amounts could differ significantly from these estimates. Our management bases its estimates and judgments on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the amounts of revenue and expenses that are not readily apparent from other sources. Additional information about these critical accounting policies may be found in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section included in our Annual Report on Form 10-K for the fiscal year ended December 29, 2012.

Comparison of Three Months Ended March 30, 2013 and March 31, 2012

Revenue

	Three Months Ended
	March 30, 2013		March 31, 2012		Dollar Change		Percent Change
			(In thousands)
Total revenue	$	106,195	$	97,807	$	8,388	8.6	%

Total revenue for the three months ended March 30, 2013 increased to $106.2 million, or 8.6%, compared to $97.8 million for the three months ended March 31, 2012. Revenue increased approximately $11.1 million, or 13.6%, in our home robots business unit and decreased approximately $3.1 million, or 21.6%, in our defense and security robots business unit.

The $11.1 million increase in revenue from our home robots business unit for the three months ended March 30, 2013 was driven by a 7.4% increase in units shipped and a 7.5% increase in net average selling price as compared to the three months ended March 31, 2012. In the three months ended March 30, 2013, domestic home robots revenue increased $9.6 million and international home robots revenue increased $1.5 million as compared to the three months ended March 31, 2012. Total home robots shipped in the three months ended March 30, 2013 were 230,000 units compared to 214,000 units in the three months ended March 31, 2012. The increase in home robots business unit revenue and units shipped was primarily attributable to a 43.9% increase in domestic sales of our home robots products, while international sales of our home robots products increased by 2.6%. The increase in domestic sales of our home robots resulted primarily from our domestic advertising campaign, strong sell-through across our domestic retailers during the three month period ended December 29, 2012, expanded distribution of the Roomba 600 and 700 series robots, and the addition of the Braava floor sweeping robot to our product lineup. Home robots business unit revenue from international sales was 66.1% of total home robots business unit

19

revenue in the three month period ending March 30, 2013 as compared to 73.3% in the three month period ended March 31, 2012. In addition, net average selling prices in the home robots business unit increased due to increased volume of higher priced products including the Roomba 600 and 700 series robot, and fewer sales of our lower priced Roomba series robots in the current quarter as compared to the prior year.

The $3.1 million decrease in revenue from our defense and security robots business unit was primarily attributable to a $1.0 million decrease in defense and security robots revenue and a $2.1 million decrease in recurring contract development revenue generated under research and development contracts. The $1.0 million decrease in defense and security robots revenue was primarily due to a decrease in sales of SUGV and FirstLook units in the three month period ended March 30, 2013 as compared to the three month period ended March 31, 2012, partially offset by an increase in sales of spare parts. Total defense and security robots shipped in the three months ended March 30, 2013 were 16 units compared to 132 units in the three months ended March 31, 2012. The $2.1 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 program.

Total cost of revenue increased to $59.7 million in the three months ended March 30, 2013, compared to $59.3 million in the three months ended March 31, 2012. The decrease is primarily due to the 87.9% decrease in defense and security units shipped offset by the 7.4% increase in home robots units shipped and the product mix of those units.

Gross Margin

Total gross margin	$	46,527		$	38,552		$	7,975	20.7	%
As a percentage of total revenue	43.8		%	39.4		%

Gross margin increased $8.0 million, or 20.7%, to $46.5 million (43.8% of revenue) in the three months ended March 30, 2013 from $38.6 million (39.4% of revenue) in the three months ended March 31, 2012. The increase in gross margin as a percentage of revenue was the result of the home robots business unit gross margin increasing 1.2 percentage points and the defense and security robots business unit gross margin increasing 17.4 percentage points. The 1.2 percentage point increase in the home robots business unit is primarily attributable to a 7.5% increase in net average selling price, driven by increased volume of higher priced robots including the Roomba 600 and 700 series, and fewer sales of our lower priced Roomba series robots in the current quarter as compared to the prior year. The 17.4 percentage point increase in the defense and security business unit is primarily attributable to lower rework and excess and obsolete inventory costs, as well as reduced compensation costs associated with a decrease in headcount in the three month period ended March 30, 2013, as compared to the three month period ended March 31, 2012.

Research and development expenses decreased $0.1 million, or 0.6%, to $14.4 million (13.6% of revenue) in the three months ended March 30, 2013 from $14.5 million (14.8% of revenue) in the three months ended March 31, 2012. Research and development expenses did not change significantly in the three months ended March 30, 2013 compared to the three months ended March 31, 2012.

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 the three months ended March 30, 2013, these expenses amounted to $1.9 million, compared to $3.0 million for the three months ended March 31, 2012. 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 $16.3 million for the three months ended March 30, 2013, compared to $17.5 million for the three months ended March 31, 2012.

Selling and marketing expenses decreased by $1.6 million, or 13.3%, to $10.7 million (10.1% of revenue) in the three months ended March 30, 2013 from $12.3 million (12.6% of revenue) in the three months ended March 31, 2012. This decrease is primarily attributable to marketing expenses incurred during the three months ended March 31, 2012 as part of our global marketing and branding efforts. We expect to incur more significant marketing expenses later in fiscal year 2013 than were incurred during the three months ended March 30, 2013.

This increase is primarily attributable to increases in stock based compensation expense, increased amortization expense resulting from the acquisition of Evolution Robotics, Inc. on October 1, 2012, and increased legal expenses in the three months ended March 30, 2013 as compared to the three months ended March 31, 2012.

Total income tax expense	$	513	$	244	$	269	110.2	%

We recorded a tax provision of $0.5 million and $0.2 million for the three month periods ended March 30, 2013 and March 31, 2012, respectively. The $0.5 million provision for the three month period ended March 30, 2013 resulted in an effective income tax rate of 5.8%. The $0.2 million provision for the three month period ended March 31, 2012 resulted in an effective income tax rate of 27.2%. The decrease in the effective income tax rate from 27.2% in the three month period ended March 31, 2012 to 5.8% in the three month period ended March 30, 2013 was primarily due to the retroactive reinstatement of federal research and development credits through December 31, 2013 during the three month period ended March 30, 2013 as part of the American Taxpayer Relief Act of 2012, which was enacted on January 2, 2013.

Liquidity and Capital Resources

At March 30, 2013, our principal sources of liquidity were cash and cash equivalents totaling $123.6 million, short-term investments of $13.9 million and accounts receivable of $27.3 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 three months ended March 30, 2013 and March 31, 2012, we spent $1.1 million and $1.6 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 is relatively low as they are generally built to order. Our contract manufacturers are responsible for purchasing and stocking the majority of components required for the production of our products, and they typically invoice us when the finished goods are shipped.

The balance of cash and short-term investments of $137.5 million at March 30, 2013 is primarily the result of cash generated by operations and our on-going focus on managing working capital. As of March 30, 2013, we did not have any borrowings outstanding under our working capital line of credit and had $1.7 million in letters of credit outstanding under our revolving letter of credit facility.

22

Discussion of Cash Flows

Net cash provided by operating activities for the three months ended March 30, 2013 was $0.2 million, a decrease of $3.6 million compared to the $3.8 million of net cash provided by operating activities for the three months ended March 31, 2012. The decrease in net cash provided by operating activities was primarily driven by a decrease in cash of $11.3 million resulting from a decrease in accounts receivable of $2.1 million in 2013 compared to a $13.4 million decrease in accounts receivable in 2012 as a result of the timing of revenue and the corresponding cash receipts, as well as a decrease in cash of $8.6 million resulting from a decrease in accounts payable of $12.7 million in 2013 compared to a decrease of $4.1 million in 2012 as a result of normal purchasing and vendor payment activities. These decreases were partially offset by an increase in cash of $7.7 million resulting from net income of $8.4 million in 2013 compared to net income of $0.7 million in 2012, and an increase of $6.2 million resulting from an increase in deferred tax assets of $0.5 million in 2013 compared to an increase of $6.7 million in 2012, primarily due to the net effect of changes in deferred tax assets and liabilities associated with operating assets and liabilities, as well as other net increases of $2.3 million due to normal operating activities.

Net cash used in investing activities for the three months ended March 30, 2013 was $4.6 million, a decrease of $0.5 million compared to the $5.1 of net cash used in investing activities for the three months ended March 31, 2012. Capital additions were $1.1 million and $1.6 million for the three months ended March 30, 2013 and March 31, 2012, respectively. The decrease in capital additions in 2013 was primarily attributable to lower spending on leasehold improvements, production tooling and enterprise software. Cash used for strategic investments was $2.0 million and $6.0 million for the three months ended March 30, 2013 and March 31, 2012, respectively.The $2.0 million used in 2013 represents an additional investment in the preferred shares of InTouch Technologies, Inc. compared to our initial investment of $6.0 million in 2012. The net purchase of investments was $1.5 million for three months ended March 30, 2013 and the net sale of investments was $2.5 million for the three months ended March 31, 2012. This activity varies from period to period based upon the maturity dates of our investments, yields on the types of short instruments in which we invest, and the level of cash available for investment.

Net cash provided by financing activities for the three months ended March 30, 2013 was $1.3 million, a decrease of $0.5 million compared to the $1.8 million of net cash provided by financing activities for the three months ended March 31, 2012. We generated $1.7 million and $1.3 million from the exercise of stock options during the three months ended March 30, 2013 and March 31, 2012, respectively. We generated $43,000 and $0.7 million of tax benefits from excess stock-based compensation deductions during the three months ended March 30, 2013 and March 31, 2012, respectively. We spent $0.5 million and $0.2 million in the payment of income tax withholdings associated with restricted stock vesting during the three months ended March 30, 2013 and March 31, 2012, respectively.

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 March 30, 2013, 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 March 30, 2013, 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.

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 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, our obligations under the credit facility may be accelerated.

As of March 30, 2013, we were in compliance with all covenants under the revolving credit facility.

23

Letter of Credit Facility

We have a revolving letter of credit facility with Bank of America, N.A. which 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 March 30, 2013, we had letters of credit outstanding of $1.7 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 March 30, 2013, 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.

24

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 and certain components. The following table describes our commitments to settle contractual obligations in cash as of March 30, 2013:

	Payments Due by Period
	Less Than 1 Year		1 to 3 Years		3 to 5 Years		More Than 5 Years		Total
	(In thousands)
Operating leases	$	2,353	$	5,657	$	5,252	$	5,683	$	18,945
Minimum contractual obligations	372		2,491		—		—		2,863
Other obligations	100		305		—		—		405
Total	$	2,825	$	8,453	$	5,252	$	5,683	$	22,213

Our minimum contractual obligations consist of obligations to key component suppliers for our home robots, which payments are incurred in the ordinary course of business. Other obligations consist of advertising agreements for corporate branding.

Off-Balance Sheet Arrangements

As of March 30, 2013, we had no off-balance sheet arrangements as defined in Item 303(a)(4) of Regulation S-K.

Recently Issued Accounting Pronouncements

See Footnote 2 to the Consolidated Financial Statements for a discussion of recently issued accounting pronouncements.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

Interest Rate Sensitivity

At March 30, 2013, we had unrestricted cash and cash equivalents of $123.6 million and short term investments of $13.9 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 March 30, 2013, 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. As of March 30, 2013, we do not have any borrowings outstanding under our working capital line of credit. As of March 30, 2013, we had letters of credit outstanding of $1.7 million under our revolving letter of credit facility.

Exchange Rate Sensitivity

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, Japanese Yen 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.

25

Item 4. Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report were effective at a reasonable assurance level in ensuring that information required to be disclosed by us in reports that we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms; and (ii) accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely discussions regarding required disclosure. We believe that a control system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the control system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

There was no change in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during the period covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Part II. Other Information

Item 1. 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 1A. Risk Factors

We operate in a rapidly changing environment that involves a number of risks that could materially affect our business, financial condition or future results, some of which are beyond our control. In addition to the other information set forth in this report, the risks and uncertainties that we believe are most important for you to consider are discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 29, 2012, which could materially affect our business, financial condition or future results. 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. There are no material changes to the Risk Factors described in our Annual Report on Form 10-K for the fiscal year ended December 29, 2012.

Item 5. 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, Jeffrey Beck, Chief Operating Officer, and Glen Weinstein, Executive Vice President and Chief Legal Officer) have entered into trading plans (each a “Plan” and collectively, the “Plans”) covering periods after the date of this quarterly report on Form 10-Q 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.

AS ADOPTED PURSUANT TO

SECTION 906 OF THE SARBANES-OXLEY ACT OF 2002

In connection with the Quarterly Report on Form 10-Q of iRobot Corporation (the “Company”) for the period ended March 30, 2013 as filed with the Securities and Exchange Commission on the date hereof (the “Report”), we, Colin M.

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. iRobot has prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America.

The accompanying unaudited financial data as of March 30, 2013 and for the three months ended March 30, 2013 and March 31, 2012 has been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. The year-end balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto included in its Annual Report on Form 10-K for the fiscal year ended December 29, 2012, filed with the SEC on February 15, 2013.

In the opinion of management, all adjustments necessary to state fairly its statement of financial position as of March 30, 2013 and results of operations and cash flows for the periods ended March 30, 2013 and March 31, 2012 have been made. The results of operations and cash flows for any interim period are not necessarily indicative of the operating results and cash flows for the full fiscal year or any future periods.

Reorganization

In fiscal year 2012, the Company initiated a reorganization that resulted in, among other things, the centralization of all of the Company's engineering and operations activities. This reorganization was completed at the beginning of fiscal year 2013. In conjunction with this reorganization, the Company reviewed the financial statement classification of its costs and expenses. As a result of this review, the Company decided to classify certain expenses differently than had been classified and presented in prior periods to provide a more clear understanding of the Company's financial performance. As part of this review, the Company also evaluated the impact of the reorganization on its segment reporting and determined that certain modifications were necessary to present the segment information as now viewed by the Company's chief operating decision maker. Although the classification of certain expenses on the income statement has changed in fiscal year 2013 as compared to prior periods, the Company recast the financial results of prior periods in a manner consistent with the fiscal year 2013 presentation for comparability purposes. The reclassified amounts reflected in the consolidated statement of income for the three months ended March 31, 2012 included herein conform to the fiscal year 2013 presentation. This reclassification of costs and expenses did not impact previously reported net income or earnings per share as the changes only impacted the categorization of costs within the consolidated statements of income for the periods in question. Consequently, the classification changes did not impact previously presented consolidated balance sheets, statements of cash flow or statements of stockholders' equity.

Revision of Consolidated Balance Sheet as of December 29, 2012

During the three month period ended March 30, 2013, the Company identified a classification error related to its reserves for uncertain tax positions on its December 29, 2012 consolidated balance sheet. The Company had recorded a gross income tax receivable in current assets and a gross uncertain tax positions liability against that receivable in current liabilities as of December 29, 2012. In addition, the Company misclassified certain uncertain tax position liabilities in current and long-term liabilities. The impact of the errors on the December 29, 2012 consolidated balance sheet was a decrease in Other Current Assets of $2.7 million, an increase in Other Assets of $0.2 million, a decrease in Accrued Expenses of $2.9 million, and an increase in Long-term Liabilities of $0.4 million. These adjustments were not considered to be material individually or in the aggregate to previously issued financial statements. The Company has revised its December 29, 2012 consolidated balance sheet to correct these errors as reflected herein. This revision had no impact on the consolidated statement of income, the consolidated statement of comprehensive income, or total cash flows from operating activities, total cash flows from investing activities, or total cash flows from financing activities.

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 end on the Saturday that falls closest to the last day of the third month of each quarter.

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 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 of home robots 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 March 30, 2013, 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.

Accounting for Share-Based Payments

The Company accounts for share-based payments to employees, including grants of employee stock options and awards in the form of restricted shares and restricted stock units by establishing the fair value of each option grant using the Black-Scholes option- pricing model and the fair value of awards based on stock price at the time of grant. The fair value of share-based payments is recorded by the Company as a charge against earnings. The Company recognizes share-based payment expense over the requisite service period of the underlying grants and awards. The Company’s share-based payment awards are accounted for as equity instruments.

Net Income Per Share

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

	Three Months Ended
	March 30, 2013		March 31, 2012
Net income	$	8,355	$	653
Weighted-average shares outstanding	27,930		27,352
Dilutive effect of employee stock options and restricted shares	628		931
Diluted weighted-average shares outstanding	28,558		28,283
Basic income per share	$	0.30	$	0.02
Diluted income per share	$	0.29	$	0.02

Restricted stock units and options to acquire representing approximately 1.1 million and 0.5 million shares of common stock for the three month periods ended March 30, 2013 and March 31, 2012, 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 examination by the Internal Revenue Service (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 2009 may still be adjusted upon examination by the IRS or state tax authorities if they either have been or will be used in a period for which the statute of limitations is still open. The IRS is currently examining the Company’s tax returns for the years 2008, 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.

The Company recorded a tax provision of $0.5 million and $0.2 million for the three month periods ended March 30, 2013 and March 31, 2012, respectively. The $0.5 million provision for the three month period ended March 30, 2013 resulted in an effective income tax rate of 5.8%. The $0.2 million provision for the three month period ended March 31, 2012 resulted in an effective income tax rate of 27.2%. In January 2013, legislation was enacted that included the extension of federal research and development tax credits. The legislation retroactively reinstated research and development tax credits for 2012 and extended them through December 31, 2013. As a result, the Company recorded a discrete benefit related to 2012 during the three month period ended March 30, 2013. The decrease in the effective income tax rate from 27.2% for the three month period ended March 31, 2012 to 5.8% for the three month period ended March 30, 2103 was primarily due to the extension of federal research and development tax credits in 2013.

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 March 30, 2013, were as follows:

	Fair Value Measurements as of March 30, 2013
	Level 1		Level 2		Level 3
	(In thousands)
Description
Assets:
Money market funds	$	86,774	$	—	$	—
Corporate bonds	—		13,869		—
Total assets measured at fair value	$	86,774	$	13,869	$	—

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
	Level 1		Level 2		Level 3
	(In thousands)
Description
Assets:
Money market funds	$	88,144	$	—	$	—
Corporate bonds	—		12,430		—
Total assets measured at fair value	$	88,144	$	12,430	$	—

In each table above, 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. The 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.

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. The Company first assesses 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.

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board ("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 impact of these amendments on the Company’s consolidated financial statements was not material.

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

Lease Obligations

Rental expense under operating leases for the three months ended March 30, 2013 and March 31, 2012 were $1.0 million and $1.1 million, respectively. Future minimum rental payments under operating leases were as follows as of March 30, 2013:

2016	2,747
2017	2,505
Thereafter	5,683
Total minimum lease payments	$	18,945

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.

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 products. The term of these indemnification agreements is generally perpetual 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 March 30, 2013 and December 29, 2012, respectively.

Warranty

The Company provides warranties on most products and has established a reserve for warranty based on identified or estimated warranty costs. The reserve is included as part of accrued expenses (Note 5) in the accompanying balance sheets.

Activity related to the warranty accrual was as follows:

Warranty usage(1)	(440		)	(1,088		)
Balance at end of period	$	6,021		$	10,132

(1) Warranty usage includes the expiration of product warranties unutilized.

Inventory

Based upon its business outlook, the Company provides purchase orders and material authorizations to its contract manufacturers for future delivery of finished goods. On the basis of these purchase orders and material authorizations, the Company’s contract manufacturers order components from their respective suppliers. Should the Company’s business outlook not materialize as expected, it may be contractually obligated to purchase from the contract manufacturers inventory they have secured on behalf of the Company, which may be in excess of customer demand. The Company continually evaluates whether any such obligation or exposure exists and records a liability in the period in which such obligations or exposure are identified.

9. Goodwill, Other Intangible Assets and Other Assets

Goodwill

The carrying amount of the Company's goodwill at March 30, 2013 is $49.0 million, of which $41.1 million resulted from the acquisition of Evolution Robotics, Inc. in October 2012 and was assigned to the home robots reporting unit. $7.9 million resulted from the acquisition of Nekton Research, LLC completed in September 2008 and was assigned to the defense and security reporting unit. In conjunction with the reorganization completed as of the beginning of the fiscal year 2013, the defense and security reporting unit was divided into two reporting units: the defense and security reporting unit and the research reporting unit. As a result, the goodwill of $7.9 million was reassigned utilizing a relative fair value allocation approach. $7.7 million and $0.2 million were reassigned to the defense and security and research reporting units, respectively. Further, the Company completed an interim impairment test for each reporting unit and did not identify any impairment.

Other Intangible Assets

Other intangible assets include the value assigned to completed technology, research contracts, and a trade name. 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 economic benefits of the intangible assets are expected to be utilized.

Intangible assets at March 30, 2013 and December 29, 2012 consisted of the following:

	March 30, 2013						December 29, 2012

Amortization expense related to acquired intangible assets was $965,000 and $93,000 for the three months ended March 30, 2013 and March 31, 2012, respectively. The estimated future amortization expense is expected to be as follows:

Other Assets

In January 2013, the Company recorded an additional investment of $2.0 million of preferred stock of InTouch Technologies, Inc. (“InTouch”), bringing its total investment to $8.0 million of preferred stock of InTouch. The total investment is 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 continue to monitor this investment to determine if facts and circumstances have changed in a manner that would require a change in accounting methodology. Additionally, the Company will continue to regularly evaluate whether or not this investment has been impaired by considering such factors as economic environment, market conditions, operational performance and other specific factors relating to the business underlying the investment. If any such impairment is identified, a reduction in the carrying value of the investment would be recorded at that time.

Industry Segment, Geographic Information and Significant Customers

8. Industry Segment, Geographic Information and Significant Customers

The Company operates in two reportable segments, the home robots business unit and the defense and security robots business unit. The nature of products and types of customers for the two segments vary significantly. As such, the segments are managed separately. As a result of the reorganization completed at the beginning of fiscal year 2013, the Company determined that certain modifications were necessary to present the segment information as now viewed by the Company's chief operating decision maker. While no new reportable segments resulted from the reorganization, certain revenue and expenses previously included in the home robots business unit and the defense and security robots business unit are now combined with other revenue and expenses and presented separately from the two reportable segments.

Home Robots

The Company’s home robots business unit offers products to consumers through a network of retail businesses throughout the United States, to various countries through international distributors and retailers, and through the Company’s on-line store. The Company’s home robots business unit includes mobile robots used in the maintenance of households.

Defense and Security

The Company’s defense and security robots business unit offers products through a small U.S. government-focused sales force. Products are also sold to a limited number of countries, other than the United States, primarily through international distributors but also through a small internationally focused sales team. The Company’s defense and security robots are used by various U.S. and foreign governments, primarily for reconnaissance and bomb disposal missions.

Other

The Company’s other revenue and cost of revenue result from other, smaller business units that do not meet the criteria of a reportable segment, as well as certain operational costs included in cost of revenue.

The table below presents segment information about revenue, cost of revenue, gross margin and income before income taxes:

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. iRobot has prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America.

The accompanying unaudited financial data as of March 30, 2013 and for the three months ended March 30, 2013 and March 31, 2012 has been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. The year-end balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto included in its Annual Report on Form 10-K for the fiscal year ended December 29, 2012, filed with the SEC on February 15, 2013.

In the opinion of management, all adjustments necessary to state fairly its statement of financial position as of March 30, 2013 and results of operations and cash flows for the periods ended March 30, 2013 and March 31, 2012 have been made. The results of operations and cash flows for any interim period are not necessarily indicative of the operating results and cash flows for the full fiscal year or any future periods.

Reorganization

Reorganization

In fiscal year 2012, the Company initiated a reorganization that resulted in, among other things, the centralization of all of the Company's engineering and operations activities. This reorganization was completed at the beginning of fiscal year 2013. In conjunction with this reorganization, the Company reviewed the financial statement classification of its costs and expenses. As a result of this review, the Company decided to classify certain expenses differently than had been classified and presented in prior periods to provide a more clear understanding of the Company's financial performance. As part of this review, the Company also evaluated the impact of the reorganization on its segment reporting and determined that certain modifications were necessary to present the segment information as now viewed by the Company's chief operating decision maker. Although the classification of certain expenses on the income statement has changed in fiscal year 2013 as compared to prior periods, the Company recast the financial results of prior periods in a manner consistent with the fiscal year 2013 presentation for comparability purposes. The reclassified amounts reflected in the consolidated statement of income for the three months ended March 31, 2012 included herein conform to the fiscal year 2013 presentation. This reclassification of costs and expenses did not impact previously reported net income or earnings per share as the changes only impacted the categorization of costs within the consolidated statements of income for the periods in question. Consequently, the classification changes did not impact previously presented consolidated balance sheets, statements of cash flow or statements of stockholders' equity.

Revision of Consolidated Balance Sheet as of December 29, 2012

Revision of Consolidated Balance Sheet as of December 29, 2012

During the three month period ended March 30, 2013, the Company identified a classification error related to its reserves for uncertain tax positions on its December 29, 2012 consolidated balance sheet. The Company had recorded a gross income tax receivable in current assets and a gross uncertain tax positions liability against that receivable in current liabilities as of December 29, 2012. In addition, the Company misclassified certain uncertain tax position liabilities in current and long-term liabilities. The impact of the errors on the December 29, 2012 consolidated balance sheet was a decrease in Other Current Assets of $2.7 million, an increase in Other Assets of $0.2 million, a decrease in Accrued Expenses of $2.9 million, and an increase in Long-term Liabilities of $0.4 million. These adjustments were not considered to be material individually or in the aggregate to previously issued financial statements. The Company has revised its December 29, 2012 consolidated balance sheet to correct these errors as reflected herein. This revision had no impact on the consolidated statement of income, the consolidated statement of comprehensive income, or total cash flows from operating activities, total cash flows from investing activities, or total cash flows from financing activities.

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 end on the Saturday that falls closest to the last day of the third month of each quarter.

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 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 of home robots 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 March 30, 2013, 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.

Accounting for Share-Based Payments

Accounting for Share-Based Payments

The Company accounts for share-based payments to employees, including grants of employee stock options and awards in the form of restricted shares and restricted stock units by establishing the fair value of each option grant using the Black-Scholes option- pricing model and the fair value of awards based on stock price at the time of grant. The fair value of share-based payments is recorded by the Company as a charge against earnings. The Company recognizes share-based payment expense over the requisite service period of the underlying grants and awards. The Company’s share-based payment awards are accounted for as equity instruments.

Net Income Per Share

Net Income Per Share

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

	Three Months Ended
	March 30, 2013		March 31, 2012
Net income	$	8,355	$	653
Weighted-average shares outstanding	27,930		27,352
Dilutive effect of employee stock options and restricted shares	628		931
Diluted weighted-average shares outstanding	28,558		28,283
Basic income per share	$	0.30	$	0.02
Diluted income per share	$	0.29	$	0.02

Restricted stock units and options to acquire representing approximately 1.1 million and 0.5 million shares of common stock for the three month periods ended March 30, 2013 and March 31, 2012, 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 examination by the Internal Revenue Service (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 2009 may still be adjusted upon examination by the IRS or state tax authorities if they either have been or will be used in a period for which the statute of limitations is still open. The IRS is currently examining the Company’s tax returns for the years 2008, 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.

The Company recorded a tax provision of $0.5 million and $0.2 million for the three month periods ended March 30, 2013 and March 31, 2012, respectively. The $0.5 million provision for the three month period ended March 30, 2013 resulted in an effective income tax rate of 5.8%. The $0.2 million provision for the three month period ended March 31, 2012 resulted in an effective income tax rate of 27.2%. In January 2013, legislation was enacted that included the extension of federal research and development tax credits. The legislation retroactively reinstated research and development tax credits for 2012 and extended them through December 31, 2013. As a result, the Company recorded a discrete benefit related to 2012 during the three month period ended March 30, 2013. The decrease in the effective income tax rate from 27.2% for the three month period ended March 31, 2012 to 5.8% for the three month period ended March 30, 2103 was primarily due to the extension of federal research and development tax credits in 2013.

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 March 30, 2013, were as follows:

	Fair Value Measurements as of March 30, 2013
	Level 1		Level 2		Level 3
	(In thousands)
Description
Assets:
Money market funds	$	86,774	$	—	$	—
Corporate bonds	—		13,869		—
Total assets measured at fair value	$	86,774	$	13,869	$	—

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
	Level 1		Level 2		Level 3
	(In thousands)
Description
Assets:
Money market funds	$	88,144	$	—	$	—
Corporate bonds	—		12,430		—
Total assets measured at fair value	$	88,144	$	12,430	$	—

In each table above, 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. The 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.

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. The Company first assesses 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.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board ("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 impact of these amendments on the Company’s consolidated financial statements was not material.

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

Stock Option Plans

4. Stock Option Plans

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 those issued under 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 March 30, 2013, there were 3,855,966 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 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.

On March 8, 2013, the Company granted to certain employees, including executive officers, an annual merit grant of stock options totaling 181,300 shares of the Company’s common stock and 331,725 restricted stock units. Additionally, an employee was granted 60,000 stock options and 30,000 restricted stock units in connection with the commencement of his employment. Each of the above stock options have a per share exercise price of $22.86, the closing price of the Company’s common stock on NASDAQ on March 8, 2013. The stock options and restricted stock units generally vest over a four year period.
