iROBOT CORPORATION
Notes To Consolidated Financial Statements
(unaudited)
1. Description of Business
     iRobot Corporation (“iRobot” or the “Company”) was incorporated in 1990 as IS Robotics, Inc. to develop robotics and artificial intelligence technologies and apply these technologies in producing and marketing robots. The majority of the Company’s revenue is generated from product sales and government and industrial research and development contracts.
     The Company is subject to risks common to companies in high-tech industries including, but not limited to, uncertainty of progress in developing technologies, new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations and uncertainty of market acceptance of products.
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 financial data as of September 30, 2006 and for the three and nine months ended September 30, 2006 and October 1, 2005 has been prepared by the Company, without audit, 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 of America 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. 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 31, 2005, filed with the SEC on March 16, 2006.
     In the opinion of management, all adjustments necessary to present a fair statement of financial position as of September 30, 2006 and results of operations and cash flows for the periods ended September 30, 2006 and October 1, 2005 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.
   Use of Estimates
     The preparation of these financial statements in conformity with accounting principles generally accepted in the United States of America 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, lease termination, 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.
   Reclassification
     Certain reclassifications have been made to the prior year financial statements to conform to the current year presentation.

   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 home robots under the terms of the customer agreement upon transfer of title to the customer, net of estimated returns, provided that collection is determined to be probable and no significant obligations remain. Sales to resellers are subject to agreements allowing for limited rights of return for defective products only, rebates and price protection. The Company has historically not taken product returns except for defective products. Accordingly, the Company reduces revenue for its estimates of liabilities for these rights at the time the related sale is recorded. The Company makes an estimate of sales returns for products sold by resellers directly or through its distributors based on historical returns experience. The Company has aggregated and analyzed historical returns from resellers and end users which form the basis of its estimate of future sales returns by resellers or end users. In accordance with Statement of Financial Accounting Standards No. 48, Revenue Recognition When 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. Revenue on firm fixed price (FFP) contracts is recognized using the percentage-of-completion method. Costs and estimated gross profits on contracts are recorded as revenue as work is performed based on the percentage that incurred costs bear to estimated total costs utilizing the most recent estimates of costs and funding. Changes in job performance, job conditions, and estimated profitability, including those arising from final contract settlements, 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, 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.
   Stock-Based Compensation
     Effective January 1, 2006, the Company adopted the provisions of SFAS No. 123(R), Share-Based Payment, which establishes accounting for equity instruments exchanged for employee services. Under the provisions of SFAS No. 123(R), share-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity grants). Prior to January 1, 2006, the Company accounted for share-based compensation to employees in accordance with Accounting Principles Board Opinion (“APB”) No. 25, Accounting for Stock Issued to Employees, and related interpretations. The Company also followed the disclosure requirements of SFAS No. 123, Accounting for Stock-Based Compensation, as amended by SFAS No. 148, Accounting for Stock-Based Compensation — Transition and Disclosure. The Company elected to adopt the modified prospective transition method as provided by SFAS No. 123(R) and, accordingly financial statement amounts for the prior periods presented in this Quarterly Report on Form 10-Q have not been restated to reflect the fair value method of expensing share-based compensation.
     Under SFAS No. 123(R), entities that become public companies after June 15, 2005 and used the minimum value method of measuring equity share options and similar instruments as a non-public company for either recognition or pro forma disclosure purposes under SFAS No. 123 must apply the provisions of SFAS No. 123(R)

prospectively to new and/or modified awards after the adoption of SFAS No. 123(R). Companies should continue to account for any portion of awards outstanding at the date of initial application of SFAS No. 123(R) using the accounting principles originally applied to those awards — either the minimum value method under SFAS No. 123 or the provisions of APB No. 25 and its related interpretive guidance. Accordingly, the Company did not record any cumulative effect of a change in accounting principle associated with the adoption of SFAS No. 123(R).
     The Company has historically granted stock options at exercise prices that equaled the fair value of its common stock as estimated by its board of directors, with input from management, as of the date of grant. Because there was no public market for the Company’s common stock prior to its initial public offering on November 9, 2005, its board of directors determined the fair value of its common stock by considering a number of objective and subjective factors, including the Company’s operating and financial performance and corporate milestones, the prices at which it sold shares of convertible preferred stock, the superior rights and preferences of securities senior to its common stock at the time of each grant, and the risk and non-liquid nature of its common stock. The Company has not historically obtained contemporaneous valuations by an unrelated valuation specialist because, at the time of the issuances of stock options, the Company believed its estimates of the fair value of its common stock to be reasonable based on the foregoing factors.
     In connection with the initial public offering, the Company retrospectively reassessed the fair value of its common stock for options granted during the period from July 1, 2004 to November 8, 2005. As a result of this reassessment, the Company determined that the estimated fair market value used in granting options for the period from July 1, 2004 to December 31, 2004 was reasonable and appropriate. Accordingly, no deferred compensation was recorded for these grants. For the period from January 1, 2005 through November 8, 2005, the Company determined that the estimated fair value of its common stock increased from $4.60 to $21.60 due to a number of factors such as, among other things, the likelihood of an initial public offering, its improving operating results and the achievement of other corporate milestones in 2005. Based upon this determination, the Company recorded deferred compensation of approximately $3.4 million in the twelve months ended December 31, 2005 under APB No. 25 relating to stock options with exercise prices below the retrospectively reassessed fair market value on the date of grant. The Company recognized associated stock-based compensation expense of $0.2 million and $0.5 million for the three and nine months ended September 30, 2006, respectively. As of September 30, 2006, the deferred stock-based compensation balance associated with these grants was $2.4 million. The Company will continue to recognize the associated stock-based compensation expense, in accordance with the provisions of APB No. 25, related to these shares of $0.2 million during the remaining three months of 2006 and $0.7 million, $0.7 million, $0.7 million and $0.1 million for 2007, 2008, 2009 and 2010, respectively.
     Under the provisions of SFAS No. 123(R), the Company recognized $0.5 million and $1.1 million of stock-based compensation expense during the three and nine months ended September 30, 2006 for stock options granted subsequent to the initial public offering. The unamortized fair value as of September 30, 2006 associated with these grants was $10.0 million with a weighted average remaining recognition period of 1.98 years.
     The fair value of each option grant for the three and nine months ended September 30, 2006 was computed on the grant date using the Black-Scholes option-pricing model with the following assumptions:
                 
    Three Months Ended   Nine Months Ended
    September 30, 2006   September 30, 2006
Risk-free interest rate
    4.77% - 5.11 %     4.32% - 5.11 %
Expected dividend yield
           
Expected life
    4.75     4.75 - 6.5 years
Expected volatility
    65 %     65 %
     The risk-free interest rate is derived from the average U.S. Treasury constant maturity rate, which approximates the rate in effect at the time of grant, commensurate with the expected life of the instrument. The dividend yield is zero based upon the fact the Company has never paid and has no present intention to pay cash dividends. The expected term calculation is based upon the simplified method provided under SEC Staff Accounting Bulletin (“SAB”) No. 107. Under SAB No. 107, the expected term is developed by averaging the contractual term of the stock option grants (7 or 10 years) with the associated vesting term (typically 4 to 5 years). Given the Company’s

initial public offering in November 2005 and the resulting short history as a public company, the Company could not rely solely on company specific historical data for purposes of establishing expected volatility. Consequently, the Company performed an analysis of several peer companies with similar expected option lives to develop an expected volatility assumption.
     Based upon the above assumptions, the weighted average fair value of each stock option granted for the three and nine months ended September 30, 2006 was $9.754 and $12.854 respectively.
     The Company has assumed a forfeiture rate of 5% for all stock options granted subsequent to the initial public offering with the exception of those issued to executives and directors for which a zero forfeiture rate has been assumed. In the future, the Company will record incremental stock-based compensation expense if the actual forfeiture rates are lower than estimated and will record a recovery of prior stock-based compensation expense if the actual forfeitures are higher than estimated.
     The Company had previously adopted the provisions of SFAS No. 123, Accounting for Stock-Based Compensation, as amended by SFAS No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure through disclosure only. The following table illustrates the effects on net income and earnings per share for the three and nine months ended October 1, 2005 as if the Company had applied the fair value recognition provisions of SFAS No. 123 to share-based employee awards.

     The fair value of each option grant for the three and nine months ended October 1, 2005 was estimated on the grant date using the Black-Scholes option pricing model with the following assumptions:
                 
    Three Months Ended   Nine Months Ended
    October 1, 2005   October 1, 2005
Risk-free interest rate
    3.88 %     3.88 %
Expected dividend yield
           
Expected life
  5 years   5 years
Expected volatility
    0.0 %     0.0 %
     In accordance with the provisions of SFAS No. 123 the Company valued options under the minimum value method up to its initial public offering on November 9, 2005, therefore options granted prior to this date had a zero expected volatility.
     Based upon the above assumptions, the weighted average fair value of each stock option granted for the three and nine months ended October 1, 2005 was $6.80 and $4.15, respectively.

   Net Income Per Share
     Prior to its initial public offering on November 9, 2005, the Company had outstanding preferred stock and, accordingly, presented basic and diluted net income per share available to common stockholders in conformity with SFAS No. 128, Earnings per Share and related interpretation Emerging Issues Task Force 03-06, Participating Securities and the Two — Class Method under FASB Statement No. 128. Basic net income per share available to common stockholders is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the period, excluding the dilutive effects of common stock equivalents. Income available to common stockholders excludes earnings allocated to participating preferred stockholders. Common stock equivalents include stock options, restricted stock and, in certain circumstances, convertible securities such as the preferred stock. Diluted net income per share assumes the conversion of the preferred stock using the “if converted” method, if dilutive, and includes the dilutive effect of stock options under the treasury stock method.
     In conjunction with the initial public offering, all outstanding shares of preferred stock were converted to common stock on a 1-for-1 basis. Consequently, the requirements of Emerging Issues Task Force 03-06 were not applicable for the three and nine months ended September 30, 2006.
     The following table presents the calculation of both basic and diluted net income per share:
                                 
    Three Months Ended     Nine Months Ended  
    September 30,     October 1,     September 30,     October 1,  
    2006     2005     2006     2005

    25,502       12,600       25,610       12,268  
 
                       
Basic earnings per share
  $ 0.43     $ 0.49     $ 0.23     $ 0.13  
Diluted earnings per share
  $ 0.39     $ 0.40     $ 0.21     $ 0.11  
     The assumed conversion of preferred stock totaling 9,557 shares was not included in the calculations for the three and nine months ended October 1, 2005 because the effect would have been antidilutive.
     Income Taxes
     Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are provided if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
     The Company monitors the realization of its deferred tax assets based on changes in circumstances, such as 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 realizability of its deferred tax assets involve significant judgments and estimates. If the Company continued to generate taxable income through profitable operations in future years it may be required to recognize these deferred tax assets through the reduction of the valuation allowance which would result in a material benefit to its results of operations in the period in which the benefit is determined, excluding the recognition of the portion of the valuation allowance which relates to stock compensation.

   Comprehensive Income
     SFAS No. 130, Reporting Comprehensive Income, establishes standards for the reporting and display of comprehensive income and its components in financial statements. The Company’s comprehensive income is equal to the Company’s net income for all periods presented.
   Recent Accounting Pronouncements
     In September 2006, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 157, Fair Value Measurements which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. This statement does not require any new fair value measurements; rather, it applies under other accounting pronouncements that require or permit fair value measurements. The provisions of SFAS No. 157 are effective for fiscal years beginning after November 15, 2007. The Company is currently assessing SFAS No. 157 and has not yet determined the impact, if any, that its adoption will have on its result of operations or financial condition.
     In September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements (“SAB 108”). SAB 108 provides guidance on how prior year misstatements should be taken into consideration when quantifying misstatements in current year financial statements for purposes of determining whether the current year’s financial statements are materially misstated. SAB 108 is effective for fiscal years ending on or after November 15, 2006. The Company does not expect the adoption of SAB 108 to have any impact on its results of operations or financial condition.
     In June 2006, FASB issued FASB Interpretation No. (“FIN”) 48, Accounting for Uncertainty in Income Taxes—An Interpretation of FASB Statement No. 109, which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 will be effective for fiscal years beginning after December 15, 2006. The Company is currently assessing FIN 48 and has not yet determined the impact, if any, that its adoption will have on its results of operations or financial condition.
     In May 2005, FASB issued SFAS No. 154, Accounting Changes and Error Corrections, which replaces APB No. 20, Accounting Changes, and SFAS No. 3, Reporting Accounting Changes in Interim Financial Statements — An Amendment of APB Opinion No. 28. SFAS No. 154 provides guidance on the accounting for and reporting of accounting changes and error corrections. It establishes retrospective application, or the latest practicable date, as the required method for reporting a change in accounting principle and the reporting of a correction of an error. SFAS No. 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. The Company adopted SFAS No. 154 effective January 1, 2006 and the adoption did not have an effect on its consolidated results of operations and financial condition.
     In November 2004, the FASB issued SFAS No. 151, Inventory Costs, an amendment of Accounting Research Bulletin (“ARB”) No. 43, Chapter 4, Inventory Pricing. SFAS No. 151 amends previous guidance regarding treatment of abnormal amounts of idle facility expense, freight, handling costs, and spoilage. SFAS No. 151 requires that those items be recognized as current period charges regardless of whether they meet the criterion of “so abnormal” which was the criterion specified in ARB No. 43. In addition, SFAS No. 151 requires that allocation of fixed production overheads to the cost of the production be based on normal capacity of the production facilities. The Company adopted SFAS No. 151 effective January 1, 2006 and the adoption did not have an effect on its consolidated results of operations and financial condition.
     From time to time, new accounting pronouncements are issued by FASB that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption.

3. Cash and Cash Equivalents
     Cash and cash equivalents include demand deposits, money market accounts, and other highly liquid investments with original maturities of three months or less at the date of acquisition. The Company invests its excess operating cash primarily in money market funds of major financial institutions. Cash equivalents are carried at cost, which approximates fair market value, and interest is accrued as earned.
4. Short-term Investments
     The Company’s investments are classified as available-for-sale and are recorded at fair value with any unrealized gain or loss recorded as an element of stockholders’ equity. The fair value of investments is determined based on quoted market prices at the reporting date for those instruments. As of September 30, 2006, investments consisted of:
                 
            Fair  
    Cost     Market Value  
    (In thousands)  
Auction Rate Debt Securities
  $   63,850     $ 63,850  
The Company did not hold any investments as of December 31, 2005.
As of September 30, 2006, the Company’s investments had maturity dates ranging from July 2020 to December 2045. Despite the long-term contractual maturities of the auction rate securities held at September 30, 2006, all of these securities are available for immediate sale and it is the Company’s intention to liquidate these securities within one year.
5. Inventory
     Inventory consists of the following at:
                 
    September 30,     December 31,  
    2006     2005  
    (In thousands)  
Raw materials

  $ 23,824     $ 15,903  
 
           
6. Stock Option Plans
     The Company has options outstanding under four stock incentive plans: the 1994 Stock Option Plan (the “1994 Plan”), the 2001 Special Stock Option Plan (the “2001 Plan”), the 2004 Stock Option and Incentive Plan (the “2004 Plan”) and the 2005 Stock Option and Incentive Plan (the “2005 Plan”). 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 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 1994 Plan, 2001 Plan, 2004 Plan and 2005 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. As of September 30, 2006, there were 715,679 shares available for future grant under the 2005 Plan.
     Options granted under the 1994 Plan, the 2001 Plan, the 2004 Plan and the 2005 Plan (the “Plans”) are subject to terms and conditions as determined by the compensation committee of the board of directors, including vesting

(unaudited)
periods. Options granted under the Plans are exercisable in full at any time subsequent to vesting, generally vest over periods from 0 to 5 years, and expire 7 or 10 years from the date of grant or, if earlier, 60 or 90 days from employee termination. Prior to the Company’s initial public offering, the exercise price for each incentive stock option was determined by the board of directors of the Company to be equal to the fair value of the common stock on the date of grant. In reaching this determination at the time of each such grant, the board of directors considered a broad range of factors, including the illiquid nature of an investment in the Company’s common stock, the Company’s historical financial performance, the Company’s future prospects and the value of preferred stock based on recent financing activities. Subsequent to the Company’s initial public offering, 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.
     Effective January 1, 2006, the Company adopted the provisions of SFAS No. 123(R), in accounting for stock options issued subsequent to this date. Prior to January 1, 2006, the Company utilized the provisions of APB No. 25 and related interpretations in accounting for options granted.
7. Accrued Expenses

8. Commitments and Contingencies
   Legal
     The Company received a letter from the United Kingdom’s Ministry of Defence (the “Customer”) dated February 9, 2004, attempting to terminate a contract for the design, development, production and support of a number of man-portable remote control vehicles for use in explosive ordnance disposal operations. The Company entered into the contract with the Customer on May 23, 2001, and substantially completed the product design and development phase of the work. The Company received payments based upon achieving a number of contract milestones and has recognized revenue based on progress under the percentage-of-completion method of accounting. In addition to the milestone payments, the Customer advanced the Company funds to purchase long-lead inventory components in advance of the production contemplated in the contract. On July 27, 2006, the Company signed an agreement with the United Kingdom’s Ministry of Defence (MoD) Defence Procurement Agency (DPA) to supply 30 iRobot PackBot EOD robots, spare parts and support in exchange for the payments received by the Company under the contract.
     Upon the signing of this agreement, and based upon the current estimate-to-complete, the Company recorded approximately $2.2 million in contract revenue and a $0.3 million reduction in cost of contract revenue thereby reducing the previously established $5.1 million reserve by $2.5 million. At September 30, 2006, the remaining $2.6 million was classified as $1.7 million in deferred revenue and $0.9 million in accrued expense.

   Lease Obligations
     The Company leases its facilities. Rental expense under operating leases for the three months ended September 30, 2006 and October 1, 2005 amounted to $0.5 million and $0.3 million, respectively, and for the nine months ended September 30, 2006 and October 1, 2005 amounted to $1.5 million and $0.9 million, respectively. Future minimum rental payments under operating leases were as follows as of September 30, 2006:
         
    Operating  
    Leases

   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 any time after execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal. Accordingly, the Company has no liabilities recorded for these agreements as of September 30, 2006 and December 31, 2005, respectively.

9. Industry Segment, Geographic Information and Significant Customers
     The Company operates in two reportable segments, the home robots division and government and industrial division.
     The nature of products and types of customers for the two segments vary significantly. As such, the segments are managed separately.
   Home Robots
     The Company’s home robots business offers products through a network of retail businesses throughout the United States and to certain countries through international distributors.

Overview
     iRobot provides robots that enable people to complete complex tasks in a better way. Founded in 1990 by roboticists who performed research at the Massachusetts Institute of Technology, 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 and Scooba floor washing robot perform time-consuming domestic chores, and our PackBot tactical military robots perform battlefield reconnaissance and bomb disposal. In addition, we are developing the Small Unmanned Ground Vehicle reconnaissance robot for the U.S. Army’s Future Combat Systems program and, in conjunction with Deere & Company, the R-Gator unmanned ground vehicle. We sell our robots to consumers through a variety of distribution channels, including chain stores and other national retailers, and our on-line store, and to the U.S. military and other government agencies worldwide.
     As of September 30, 2006, we had 347 full-time employees. We have developed expertise in most 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, thereby reducing the time, cost and risk of product development. We believe that our significant expertise in robot design and engineering, combined with our management team’s experience in military and consumer markets, positions us to capitalize on the expected growth in the market for robots.
     Although we have successfully launched home robot and military 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 home robot and military 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.
Critical Accounting Policies and Estimates
     The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America 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; valuation allowances (specifically sales returns and other 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

17

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.
     Effective January 1, 2006, we adopted the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 123(R), Share-Based Payment, which establishes accounting for equity instruments exchanged for employee services. Under the provisions of SFAS No. 123(R), share-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity grants). Prior to January 1, 2006, we accounted for share-based compensation to employees in accordance with Accounting Principles Board Opinion (“APB”) No. 25, Accounting for Stock Issued to Employees, and related interpretations. We also followed the disclosure requirements of SFAS No. 123, Accounting for Stock-Based Compensation, as amended by SFAS No. 148, Accounting for Stock-Based Compensation — Transition and Disclosure. We elected to adopt the modified prospective transition method as provided by SFAS No. 123(R) and, accordingly financial statement amounts for the prior periods presented in this Quarterly Report on Form 10-Q have not been restated to reflect the fair value method of expensing share-based compensation.
     Under SFAS No. 123(R), entities that become public companies after June 15, 2005 and used the minimum value method of measuring equity share options and similar instruments as a non-public company for either recognition or pro forma disclosure purposes under SFAS No. 123 shall apply the provisions of SFAS No. 123(R) prospectively to new and/or modified awards after the adoption of SFAS No. 123(R). Companies should continue to account for any portion of awards outstanding at the date of initial application of SFAS No. 123(R) using the accounting principles originally applied to those awards — either the minimum value method under SFAS No. 123 or the provisions of APB No. 25 and its related interpretive guidance. Accordingly, we did not record any cumulative effect of a change in accounting principle associated with the adoption of SFAS No. 123(R). Additionally, since we valued options under the minimum value method up to our initial public offering on November 9, 2005, options granted prior to this date had a zero expected volatility. Prior to our initial public offering, we had accounted for certain option grants under APB 25. As of September 30, 2006, the deferred stock-based compensation balance associated with these grants was $2.4 million. We will continue to recognize the associated stock-based compensation expense, in accordance with the provisions of APB No. 25, related to these shares of $0.2 million during the remaining three months of 2006 and $0.7 million, $0.7 million, $0.7 million and $0.1million for 2007, 2008, 2009 and 2010, respectively.
     Under the provisions of SFAS No. 123(R), we recognized $0.5 million and $1.1 million of stock-based compensation expense during the three and nine months ended September 30, 2006 for stock options granted subsequent to the initial public offering. The unamortized fair value as of September 30, 2006 associated with these grants was $10.0 million with a weighted average remaining recognition period of 1.98 years.
     The fair value of each option grant for the three and nine months ended September 30, 2006 was computed on the grant date using the Black-Scholes option-pricing model with the following assumptions:
                 
    Three Months Ended   Nine Months Ended
    September 30, 2006   September 30, 2006
Risk-free interest rate
    4.77% - 5.11 %     4.32% - 5.11 %
Expected dividend yield
           
Expected life
  4.75 years     4.75 - 6.5 years  
Expected volatility
    65 %     65 %
     The risk-free interest rate is derived from the average U.S. Treasury constant maturity rate, which approximates the rate in effect at the time of grant, commensurate with the expected life of the instrument. The dividend yield is zero based upon the fact that we have never paid and have no present intention to pay cash dividends. The expected term calculation is based upon the simplified method provided under SEC Staff Accounting Bulletin (“SAB”) No. 107. Under SAB No. 107, the expected term is developed by averaging the contractual term of the stock option grants (7 or 10 years) with the associated vesting term (typically 4 to 5 years). Given our initial public offering in November 2005 and the resulting short history as a public company, we could not rely solely on company specific historical data for purposes of establishing expected volatility. Consequently, we performed an analysis of several peer companies with similar expected option lives to develop an expected volatility assumption.

Table of Contents

     Based upon the above assumptions, the weighted average fair value of each stock option granted for the three and nine months ended September 30, 2006 was $9.754 and $12.854 respectively.
     We have assumed a forfeiture rate of 5% for all stock options granted subsequent to the initial public offering with the exception of those issued to executives and directors for which a zero forfeiture rate has been assumed. In the future, we will record incremental stock-based compensation expense if the actual forfeiture rates are lower than estimated and will record a recovery of prior stock-based compensation expense if the actual forfeitures are higher than estimated.
     SFAS No. 123(R) requires significant judgment and the use of estimates, particularly surrounding assumptions such as stock price volatility and expected option lives, as well as expected option forfeiture rates to value equity-based compensation. There is little experience or guidance with respect to developing these assumptions and models. There is also uncertainty as to how the standard will be interpreted and applied as more companies adopt the standard and companies and their advisors gain experience with the standard. SFAS No. 123(R) requires the recognition of the fair value of stock-based compensation in net income. Refer to Note 2 — Summary of Significant Accounting Policies in our notes to our consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for more discussion.
     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 31, 2005.

     Total revenue for the three months ended September 30, 2006 increased to $55.0 million, or 4.9%, compared to $52.5 million for the three months ended October 1, 2005. Revenue decreased approximately $9.8 million, or 24.2%, in our home robots business and increased approximately $12.4 million, or 102.3%, in our government and industrial business. The $9.8 million decrease in revenue from our home robots division was driven by a 4.7% decrease in net average selling prices and a 21.6% decrease in unit shipments resulting from a change in customer buying patterns due to our improved logistics capabilities which allow for shorter lead-time purchases as compared to the three months ended October 1, 2005. Total home floor care robots shipped in the three months ended September 30, 2006 was approximately 221,000 units compared to approximately 282,000 units in the three months ended October 1, 2005. The $12.4 million increase in revenue from our government and industrial business for the three months ended September 30, 2006 as compared to three months ended October 1, 2005 was due to a 78.7% increase in unit shipments of our military robots combined with a 6.1% increase in associated net average selling prices, a 17.6% increase in recurring contract development revenue generated under funded research and development contracts and the one-time impact of $2.2 million associated with the United Kingdom Ministry of Defence contract modification. Also included in this $12.4 million growth was an increase of approximately $3.5 million in product life cycle revenue (robot spares), which was primarily driven by the continued demand for our military robots, as compared to $1.6 million of product life cycle revenue in the three months ended October 1, 2005. Total military robot units shipped in the three months ended September 30, 2006 was 109 compared to 61 in the three months ended October 1, 2005.
     Total revenue for the nine months ended September 30, 2006 increased to $127.8 million, or 33.9%, compared to $95.5 million for the nine months ended October 1, 2005. Revenue increased approximately $10.6 million, or 17.7%, in our home robots business and $21.8 million, or 61.5%, in our government and industrial business, respectively. The $10.6 million increase in revenue from our home robots division was driven primarily by the initial distribution into the retail channel of our Scooba floor washing robot, which was released late in 2005, continued demand for our Roomba floor vacuuming robot and an 8.9% increase in net average selling prices. Total home floor care robots shipped in the nine months ended September 30, 2006 was approximately 458,000 units compared to approximately 428,000 units in the nine months ended October 1, 2005. Included within this unit increase were a significant number of Scooba floor washing robots associated with the initial distribution into the retail channel in the first quarter. The $21.8 million increase in revenue from our government and industrial business for the nine months ended September 30, 2006 as compared to nine months ended October 1, 2005 was due to a 34.7% increase in the number of military robots shipped combined with an 8.9% increase in associated net average selling prices, a 26.8% increase in recurring contract revenues generated under funded research and development contracts and the one-time impact of $2.2 million associated with the United Kingdom Ministry of Defence contract modification. Also included in this $21.8 million growth was an increase of approximately $6.9 million in product life cycle revenue (robot spares), which was primarily driven by the increased demand for our military robots, as compared to $3.5 million of product life cycle revenue in the nine months ended October 1, 2005. Total military robot units shipped in the nine months ended September 30, 2006 was 264 compared to 196 in the nine months ended October 1, 2005. The majority of this unit increase was related to 209 units shipped under our contract with the Naval Sea Systems Command for Man Transportable Robotics Systems.

As a percentage of total revenue
    58.2 %     60.5 %                     63.3 %     67.3 %                
     Total cost of revenue increased to $32.1 million in the three months ended September 30, 2006, compared to $31.8 million in the three months ended October 1, 2005. The increase is due to the higher costs associated with the 78.7% increase in the unit sales of our government and industrial robots and the 17.6% increase in recurring contract revenues generated under funded research and development contracts offset by a reduction in costs associated with the 21.6% decrease in the unit sales of our home floor care robots in the three months ended September 30, 2006 as compared to the three months ended October 1, 2005.
     The home robots division cost of revenue increased as a percent of revenue by 2.1 percentage points in the three months ended September 30, 2006 over the three months ended October 1, 2005. This increase was attributable to the above-mentioned reduction in average selling prices, offset partially by a reduction in average unit costs, and higher manufacturing overhead and warranty costs as compared to the three months ended October 1, 2005. The government and industrial robots division cost of revenue decreased as a percent of revenue by 17.7 percentage points in the three months ended September 30, 2006 as compared to the three months ended October 1, 2005. This decrease was due primarily to a the above-mentioned increase in average selling prices, a reduction in the average unit cost of product sold, higher margins on increased product life cycle revenue, reduced manufacturing overhead and a $0.3 million reduction in costs of contract revenue directly related to the United Kingdom Ministry of Defence contract modification.
     Total cost of revenue increased to $80.9 million in the nine months ended September 30, 2006, compared to $64.3 million in the nine months ended October 1, 2005. The increase is primarily attributable to a 7.0% increase in the unit sales of our home floor care robots, a 34.7% increase in the unit sales of our military robots and higher costs associated with a 26.8% increase in recurring contract revenues generated under funded research and development contracts in the nine months ended September 30, 2006 as compared to the nine months ended October 1, 2005.
     The home robots division cost of revenue increased as a percent of revenue by 0.2 percentage points in the nine months ended September 30, 2006 over the nine months ended October 1, 2005. This increase was attributable to the above-mentioned increase in average selling prices, offset by an increase in average unit costs, as a result of a shift in the product mix of the home floor care robots that we sold. In particular, the average unit cost increase was largely attributable to a significant number of Scooba floor washing robots shipped in the nine months ended September 30, 2006. Our Scooba floor washing robot carries a higher per unit cost than our Roomba floor vacuuming robot which represented 100% of home floor care robots shipped in the nine months ended October 1, 2005. The government and industrial robots division cost of revenue decreased as a percent of revenue by 12.1 percentage points for the nine months ended September 30, 2006 as compared to the nine months ended October 1, 2005. This decrease was due primarily to a the above-mentioned increase in average selling prices, a reduction in the average unit cost of product sold, higher margins on increased product life cycle revenue, reduced manufacturing overhead and a $0.3 million reduction in costs of contract revenue directly related to the United Kingdom Ministry of Defence contract modification.

     Gross profit increased 11.0% to $23.0 million in the three months ended September 30, 2006, from $20.7 million in the three months ended October 1, 2005. Gross profit as a percentage of revenue increased to 41.8% in the three months ended September 30, 2006 from 39.5% of revenue in the three months ended October 1, 2005. This 2.3 percentage point increase in gross profit was the result of the home robots division gross profit decreasing 2.1 percentage points and the government and industrial division increasing 17.7 percentage points. Additionally, the home robots division, which carries a higher overall gross profit percentage than the government and industrial division accounted for 56.2% of total gross profit in the three months ended September 30, 2006 as compared to 86.3% in the three months ended October 1, 2005. Included in the total gross profit was $2.5 million associated with the United Kingdom Ministry of Defence contract modification, which contributed 3.1 percentage points in gross profit for the three months ended September 30, 2006
     Gross profit increased 50.6% to $47.0 million in the nine months ended September 30, 2006, from $31.2 million in the nine months ended October 1, 2005. Gross profit as a percentage of revenue increased to 36.7% in the nine months ended September 30, 2006 from 32.7% of revenue in the nine months ended October 1, 2005. This 4.0 percentage increase in gross profit was the result of the home robots division gross profit decreasing 0.2 percentage points and the government and industrial gross profit increasing 12.1 percentage points. Additionally, the home robots division, which carries a higher overall gross profit than the government and industrial division, accounting for 57.2% of total gross profit in the nine months ended September 30, 2006 as compared to 73.6% in the nine months ended October 1, 2005. Included in the total gross profit was $2.5 million associated with the United Kingdom Ministry of Defence contract modification, which contributed 1.3 percentage points in gross profit for the nine months ended September 30, 2006

The increase in research and development expenses is primarily due to an increase of $0.9 million in compensation and benefit related expenses attributed to increased headcount. Consulting and related material costs associated with internal research projects increased by $0.3 million and $0.5 million, respectively. Additionally, $0.1 million of the increase relates to increased occupancy and depreciation expenses that include the addition of our Mysore, India office, which opened in late 2005, as well as increased depreciation expense on computer equipment related to increased headcount.
     Research and development expenses increased by $2.6 million or 31.3% to $10.9 million (8.6% percent of revenue) in the nine months ended September 30, 2006, from $8.3 million (8.7% of revenue) for the nine months ended October 1, 2005. The increase in research and development expense is primarily due to an increase of $2.7 million in compensation and benefit related expenses attributed to increased headcount. Consulting and related material costs associated with internal research projects increased by $0.3 million and $0.6 million, respectively. Additionally, $0.4 million of the increase related to increased occupancy and depreciation expenses that include the addition of the Mysore, India office, which opened in late 2005, as well as increased depreciation expense on computer equipment related to increased headcount. These increases were offset by a reduction of $1.7 million in internally funded research and development projects primarily related to the Scooba floor washing robot, which was launched late in the fourth quarter of 2005.

     Overall research and development headcount increased to 91 at September 30, 2006 compared to 68 as of October 1, 2005, an increase of 23 employees or 34% growth.
     We intend to accelerate our investment in research and development for the balance of fiscal 2006. Accordingly, we anticipate that research and development expenses will be between 8.5% and 9.0% of revenue for the full year.
     In addition to our internal research and development activities discussed above, we incur research and development expenses under funded development arrangements with both governments and industrial third parties. For the three and nine months ended September 30, 2006, these expenses amounted to $3.7 million and $11.2 million compared to $3.2 million and $9.0 million for the comparable three and nine month periods ended October 1, 2005, respectively. In accordance with generally accepted accounting principles, these expenses have been classified as cost of revenue rather than research and development expense.

     Selling and marketing expenses decreased by $0.2 million or 3.6% to $4.7 million (8.6% of revenue) in the three months ended September 30, 2006 from $4.9 million (9.3% of revenue) in the three months ended October 1, 2005. The decrease in selling and marketing expense was primarily driven by a decrease of $1.1 million in direct marketing and television media and production costs in the home robot division as compared to the three months ended October 1, 2005. Additionally, agency fees and marketing display costs decreased by $0.4 million. These decreases were partially offset by $0.3 million in increased customer service costs and $0.3 million in direct fulfillment costs, attributed to an increase in our direct business. Government and industrial division expenses were up $0.4 million from the comparable quarter last year due primarily to an increase in compensation and benefit as well as travel related expenses. Corporate sales and marketing increased $0.2 million which relates to public relations expenses not incurred in the prior year in which we were a private company.
     Selling and marketing expenses increased by $7.6 million or 65.7% to $19.2 million (15.0% of revenue) in the nine months ended September 30, 2006 from $11.6 million (12.1% of revenue) in the nine months ended October 1, 2005. The increase in selling and marketing expense was primarily driven by increased home robot division selling and marketing expense increase of $5.5 million over the comparable nine months ended October 1, 2005. This increase was primarily made up of $1.4 million of increased television advertising and related productions costs on Scooba and Roomba, $1.1 million increased in direct fulfillment costs, $0.6 million increased compensation and benefit related expense, $1.0 million increase in marketing display and on-line media advertising, $0.9 million increased cooperative advertising and $0.7 million increase in customer service costs. All of these increases are attributable to increased home robot revenue year-over-year of $10.6 million. Government and industrial division expenses were up $1.2 million from the comparable nine months last year due primarily to $0.5 million of increased bid and proposal activities and $0.3 million of increased compensation and benefit related expense attributed to incremental headcount. Corporate sales and marketing increased $0.9 million of which $0.6 million relates to public relations expenses.
     For the balance of fiscal 2006, we expect to aggressively invest in national advertising and direct marketing in support of the holiday buying season. Accordingly, we anticipate that selling and marketing expenses will increase in absolute dollars and will be between 18.0% and 19.0% of revenue for the full year.
     Overall selling and marketing headcount increased to 29 at September 30, 2006 compared to 22 as of October 1, 2005, an increase of 7 employees or 32% growth.

Liquidity and Capital Resources
     At September 30, 2006 our principal sources of liquidity were cash and cash equivalents totaling $8.3 million, short-term investments of $63.9 million, and accounts receivable of $30.6 million. Prior to our initial public offering in November 2005, we funded our growth primarily with proceeds from the issuance of convertible preferred stock for aggregate net cash proceeds of $37.5 million, occasional borrowings under a working capital line of credit and cash generated from operations. In the initial public offering, we raised $70.4 million net of underwriting commissions, professional fees and other expenses associated with the offering.
     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 and product-specific production tooling and test equipment. In the nine month periods ending September 30, 2006 and October 1, 2005, we spent $3.8 million and $3.9 million, respectively, on capital equipment.
     Our home robots product sales are, and are expected to continue to be, highly seasonal. This seasonality typically results in a break even or net use of cash in support of operating needs during the first half of the year with the low point generally occurring in the middle of the third quarter, and a favorable cash flow during the second half of the year.
     Discussion of Cash Flows
     Net cash used by our operating activities in the nine months ended September 30, 2006 was $0.8 million compared to net cash used by operating activities of $6.8 million in the nine months ended October 1, 2005. The cash used by our operating activities in the nine months ended September 30, 2006 was primarily due to an increase in accounts receivable (including unbilled revenue) of $7.3 million and an increase in inventory of $7.9 million in anticipation of the holiday buying season, offset by net income of $5.3 million, a decrease in other assets of $0.4 million, and a decrease in liabilities of $4.1 million. In addition, in the nine months ended September 30, 2006, we had depreciation and amortization of approximately $2.7 million and stock-based compensation of $1.8 million, both of which are non-cash expenses. The cash used by our operating activities in the nine months ended October 1, 2005 was primarily due to an increase in accounts receivable (including unbilled revenue) of $14.7 million, an increase in inventory of $6.7 million in anticipation of the holiday buying season, and an increase in other assets of $1.2 million, partially offset by net income of 2.6 million and an increase in total liabilities of approximately $11.4 million. In addition, in the nine months ended October 1, 2005, we had $1.4 million of depreciation expense and approximately $0.4 million in stock-based compensation, both of which are non-cash expenses.
     Net cash used in our investing activities was $67.7 million in the nine months ended September 30, 2006 and $3.9 million in the nine months ended October 1, 2005. Investing activities in the nine months ended September 30, 2006 represent the purchase of short-term investments of $108.2 million and capital equipment of $3.8 million,

25


Table of Contents

offset by the sale of short-term investments of $44.3 million. Investing activities in the nine months ended October 1, 2005 represent the purchase of capital equipment.
     Net cash provided by our financing activities was approximately $0.7 million in the nine months ended September 30, 2006 and $0.5 million in the nine months ended October 1, 2005 consisting primarily of proceeds from the exercise of common stock options.
     The majority of our long-lived assets for the nine months ended September 30, 2006 and October 1, 2005 are located in the United States. However, we have invested in production tooling for the manufacture of the Roomba and Scooba product lines in China.
     Historically, we have incurred significant losses, largely attributable to our investment in internally funded research and development. Based on our historical product development efforts, we launched our first commercial products, our Roomba floor vacuuming robot and our PackBot tactical military robot, in fiscal 2002. Since fiscal 2002, our revenue has significantly increased, our investment in internally-funded research and development has declined as a percentage of revenue, and we achieved profitability in both fiscal 2004 and fiscal 2005. We have not historically invested significantly in property, plant and equipment, primarily as a result of our outsourced approach to manufacturing that provides significant flexibility in both managing inventory levels and financing our inventory. Our home robot revenue has been highly seasonal. This seasonality tends to result in a break even or net use of cash during the first half of the year and significant generation of cash in the second half of the year. Given the recent success of our products and resulting growth in revenue, we believe that existing cash and cash equivalents, short-term investments, cash provided by operating activities and funds available through our bank line of credit will be sufficient to meet our working capital and capital expenditure needs for the foreseeable future.
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 our existing working capital line of credit, working capital and funds provided by operating activities. In addition, 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. Although we are currently not a party to any agreement or letter of intent with respect to potential investments in, or acquisitions of, businesses, services or technologies, we may enter into these types of arrangements in the future, which could also require us to seek additional equity or debt financing. Additional funds may not be available on terms favorable to us or at all.

     Contractual Obligations
     We generally do not enter into binding purchase commitments. Our principal commitments consist of obligations under our working capital line of credit, leases for office space and minimum contractual obligations for services. The following table describes our commitments to settle contractual obligations in cash as September 30, 2006:

Off-Balance Sheet Arrangements
     As of September 30, 2006, we had no off-balance sheet arrangements as defined in Item 303(a)(4) of Regulation S-K.
Foreign Operations
     Nearly all of our revenue is derived from transactions denominated in U.S. dollars, even though 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.
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 September 30, 2006, we had unrestricted cash and cash equivalents of $8.3 million and short-term investments of $63.9 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 principal amount of the investment to fluctuate. To minimize this risk in the future, we intend to maintain our portfolio of cash equivalents and short-term investments in a variety of securities, including auction rate 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 September 30, 2006, all of our cash equivalents were held in money market accounts and our short-term investments were comprised of auction rate securities.
     Our exposure to market risk also relates to the increase or decrease in the amount of interest expense we would be required to pay on outstanding debt instruments, primarily certain borrowings under our bank line of credit. The advances under this line of credit bear a variable rate of interest determined as a function of the prime rate or the published LIBOR rate at the time of the borrowing. At September 30, 2006, there were no amounts outstanding under our working capital line of credit.
Exchange Rate Sensitivity
     Nearly all of our revenue is derived from transactions denominated in U.S. dollars, even though 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.

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 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 in ensuring that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. 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 1A. Risk Factors
     We operate in a rapidly changing environment that involves a number of risks, some of which are beyond our control. In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2005, which could materially affect our business, financial condition or future results. In addition to the risks described in our Annual Report on Form 10-K, you are urged to consider the risk set forth below which may affect our future operating results. These are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or operating results
We recently introduced our Scooba home robot product line, and if this new product line does not generate significant sales or support the suggested unit pricing, our revenue and operating results would be negatively impacted.
     In December 2005, we made our Scooba floor washing robot available for volume distribution. We have limited experience with the enhancement, development and introduction of new product lines. In connection with the market introduction of Scooba, our retail distributors placed initial orders for Scooba robots late in the fourth quarter of 2005 and in the first quarter of 2006. The suggested retail price for our initial line of Scooba robots has been and is $399 per unit. A significant number of retail outlets independently began to offer and are offering Scooba robots for a discounted price per unit of less than $300. We have devoted significant time and have incurred significant expenses in connection with developing an extension of our Scooba line of floor washing robots with a suggested retail price of less than $300, which was introduced toward the end of the second quarter of 2006. We are unable to determine at this time whether any of our Scooba floor washing robots will attain market acceptance, at any price, or generate significant sales to consumers. Our revenues and operating results in 2006 and in the future will depend in large part on the success of this product line, and our revenues and operating results will be negatively impacted if this product line does not generate significant sales to consumers or support pricing that allows us to achieve an acceptable gross margin.

Item 5. Other Information
     Our policy governing transactions in our securities by 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 officers (including Colin Angle, Chief Executive Officer; Helen Greiner, Chairman; Dr. Rodney Brooks, Chief Technology Officer; Geoffrey Clear, Senior Vice President, Chief Financial Officer & Treasurer; Joseph Dyer, President, Government & Industrial Robots; Gregory White, President, Home Robots; and Glen Weinstein, Senior Vice President, General Counsel & Secretary) of the Company have entered into a trading plan (each a “Plan” and collectively, the “Plans”) covering periods after the date of this Quarterly Report 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 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. However, we undertake no obligation to update or revise the information provided herein, including for revision or termination of an established trading plan, other than in such quarterly and annual reports.
