Investments in debt and equity securities which are categorized neither as trading securities nor held-to-maturity securities and which are intended be sold or mature within one year from the balance sheet date or the normal operating cycle, whichever is longer. Such securities are reported at fair value; unrealized gains (losses) related to Available-for-sale Securities are excluded from earnings and reported in a separate component of shareholders' equity (other comprehensive income), unless the Available-for-sale security is designated as a hedge or is determined to have had an other than temporary decline in fair value below its amortized cost basis. All or a portion of the unrealized holding gain (loss) of an Available-for-sale security that is designated as being hedged in a fair value hedge is recognized in earnings during the period of the hedge, as are other than temporary declines in fair value below the cost basis for investments in equity securities and debt securities that an entity intends to sell or it is more likely than not that it will be required to sell before the recovery of its amortized cost basis.

Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).

For entities that net deferred tax assets and tax liabilities, represents the net amount of deferred tax assets (after reduction for valuation allowance) and liabilities as of the balance sheet date, which result from applying the applicable enacted tax rate to net temporary differences and carryforwards pertaining to assets or liabilities that are classified as current in the financial statements, or that are expected to reverse in the next twelve months (or normal operating cycle, if longer). A temporary difference is a difference between the tax basis of an asset or liability and its carrying amount in the financial statements prepared in accordance with generally accepted accounting principles that will reverse in ensuing periods. In a classified statement of financial position, an enterprise separates deferred tax liabilities and assets into a current amount and a noncurrent amount. Deferred tax liabilities and assets are classified as current or noncurrent based on the classification of the related asset or liability for financial reporting. A deferred tax liability or asset that is not related to an asset or liability for financial reporting, including deferred tax assets related to carryforwards, are classified according to the expected reversal date of the temporary difference.

Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).

| Summary of Significant Accounting Policies |
Basis of Presentation The accompanying consolidated financial statements include those of iRobot and its subsidiaries, after elimination of all intercompany accounts and transactions. In addition, certain prior year amounts have been reclassified to conform with the current year presentation. iRobot has prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. Use of Estimates The preparation of these financial statements in conformity with accounting principles generally accepted in the United States requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates these estimates and judgments, including those related to revenue recognition, sales returns, bad debts, warranty claims, inventory reserves, valuation of investments, assumptions used in valuing stock-based compensation instruments and income taxes. The Company bases these estimates on historical and anticipated results, and trends and on various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results may differ from the Company’s estimates. Fiscal Year-End The Company operates and reports using a 52-53 week fiscal year ending on the Saturday closest to December 31. Accordingly, the Company’s fiscal quarters will end on the Saturday that falls closest to the last day of the third month of each quarter. Cash and Cash Equivalents The Company considers all highly liquid investments with an original or remaining maturity of three months or less at the time of purchase to be cash equivalents. The Company invests its excess cash primarily in money market funds or savings accounts of major financial institutions. Accordingly, its cash equivalents are subject to minimal credit and market risk. At December 31, 2011 and January 1, 2011, cash equivalents were comprised of money market funds totaling $117.2 million and $5.1 million, respectively. These cash equivalents are carried at cost, which approximates fair value.
Short Term Investments The Company’s investments are classified as available-for-sale and are recorded at fair value with any unrealized gain or loss recorded as an element of stockholders’ equity. The fair value of investments is determined based on quoted market prices at the reporting date for those instruments. As of December 31, 2011 and January 1, 2011, investments consisted of:
As of December 31, 2011, the Company’s investments had maturity dates ranging from October 2012 to November 2014. Revenue Recognition The Company derives its revenue from product sales, government research and development contracts, and commercial research and development contracts. The Company sells products directly to customers and indirectly through resellers and distributors. The Company recognizes revenue from sales of home robots under the terms of the customer agreement upon transfer of title and risk of loss to the customer, net of estimated returns, provided that collection is determined to be reasonably assured and no significant obligations remain. Sales to domestic resellers are typically subject to agreements allowing for limited rights of return, rebates and price protection. Accordingly, the Company reduces revenue for its estimates of liabilities for these rights of return at the time the related sale is recorded. The Company makes an estimate of sales returns for products sold by domestic resellers directly based on historical returns experience and other relevant data. The Company’s international distributor agreements do not currently allow for product returns and, as a result, no reserve for returns is established for this group of customers. The Company has aggregated and analyzed historical returns from domestic resellers and end users which form the basis of its estimate of future sales returns by resellers or end users. When a right of return exists, the provision for these estimated returns is recorded as a reduction of revenue at the time that the related revenue is recorded. If actual returns differ significantly from its estimates, such differences could have a material impact on the Company’s results of operations for the period in which the returns become known. The estimates for returns are adjusted periodically based upon historical rates of returns. The estimates and reserve for rebates and price protection are based on specific programs, expected usage and historical experience. Actual results could differ from these estimates. Under cost-plus-fixed-fee (“CPFF”) type contracts, the Company recognizes revenue based on costs incurred plus a pro rata portion of the total fixed fee. Costs incurred include labor and material that are directly associated with individual CPFF contracts plus indirect overhead and general and administrative type costs based upon billing rates submitted by the Company to the Defense Contract Management Agency (“DCMA”). Annually, the Company submits final indirect billing rates to DCMA based upon actual costs incurred throughout the year. In the situation where the Company’s final actual billing rates are greater than the provisional rates currently in effect, the Company records a cumulative revenue adjustment in the period in which the rate differential is collected from the customer. These final billing rates are subject to audit by the Defense Contract Audit Agency (“DCAA”), which can occur several years after the final billing rates are submitted and may result in material adjustments to revenue recognized based on estimated final billing rates. As of December 31, 2011, fiscal years 2007, 2008, 2009, 2010 and 2011 are open for audit by DCAA. In the situation where the Company’s anticipated actual billing rates will be lower than the provisional rates currently in effect, the Company records a cumulative revenue adjustment in the period in which the rate differential is identified. Revenue on firm fixed price (“FFP”) contracts is recognized using the percentage-of-completion method. For government product FFP contracts, revenue is recognized as the product is shipped or in accordance with the contract terms. Costs and estimated gross margins on contracts are recorded as revenue as work is performed based on the percentage that incurred costs compare to estimated total costs utilizing the most recent estimates of costs and funding. Changes in job performance, job conditions, and estimated profitability, including those arising from final contract settlements and government audits, may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Since many contracts extend over a long period of time, revisions in cost and funding estimates during the progress of work have the effect of adjusting earnings applicable to past performance in the current period. When the current contract estimate indicates a loss, a provision is made for the total anticipated loss in the current period. Revenue earned in excess of billings, if any, is recorded as unbilled revenue. Billings in excess of revenue earned, if any, are recorded as deferred revenue. Allowance for Doubtful Accounts The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivable that may not be collected. The allowance is based upon an assessment of customer creditworthiness, historical payment experience and the age of outstanding receivables. Activity related to the allowance for doubtful accounts was as follows:
Inventory Inventory is stated at the lower of cost or net realizable value with cost being determined using the first-in, first-out (FIFO) method. The Company maintains a reserve for inventory items to provide for an estimated amount of excess or obsolete inventory. Activity related to the inventory reserve was as follows:
Property and Equipment Property and equipment are recorded at cost and consist primarily of computer equipment, leasehold improvements, business applications software and machinery. Depreciation is computed using the straight-line method over the estimated useful lives as follows:
Expenditures for additions, renewals and betterments of plant and equipment are capitalized. Expenditures for repairs and maintenance are charged to expense as incurred. As assets are retired or sold, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is credited or charged to operations. Long-Lived Assets, including Purchased Intangible Assets The Company periodically evaluates the recoverability of long-lived assets, including other purchased intangible assets whenever events and changes in circumstances, such as reductions in demand or significant economic slowdowns in the industry, indicate that the carrying amount of an asset may not be fully recoverable. When indicators of impairment are present, the carrying values of the asset group are evaluated in relation to the future undiscounted cash flows of the underlying business. The net book value of the underlying asset is adjusted to fair value if the sum of the expected discounted cash flows is less than book value. Fair values are based on estimates of market prices and assumptions concerning the amount and timing of estimated future cash flows and assumed discount rates, reflecting varying degrees of perceived risk. There were no impairment charges recorded during any of the periods presented. Goodwill Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. The Company evaluates goodwill for impairment at the reporting unit level (operating segment or one level below an operating segment) annually or more frequently if the Company believes indicators of impairment exist. In 2011, the Company early adopted the new provisions issued by the Financial Accounting Standards Board (“FASB”) that intended to simplify goodwill impairment testing. The updated guidance permits the Company to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then a two-step goodwill impairment test is performed. The first step of the impairment test involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. If the carrying amount of a reporting unit exceeds the reporting unit’s fair value, the Company performs the second step of the goodwill impairment test to determine the amount of impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill.
Research and Development Costs incurred in the research and development of the Company’s products, classified as cost of contract and research and development, are expensed as incurred. Internal Use Software The Company capitalizes costs associated with the development and implementation of software obtained for internal use. At December 31, 2011 and January 1, 2011, the Company had $8.3 million and $5.8 million respectively, of costs related to enterprise-wide software included in fixed assets. Capitalized costs are being amortized over the assets’ estimated useful lives. The Company has recorded $0.9 million, $0.9 million and $0.9 million of amortization expense for the years ended December 31, 2011, January 1, 2011 and January 2, 2010, respectively. Concentration of Credit Risk and Significant Customers The Company maintains its cash in bank deposit accounts at high quality financial institutions. The individual balances, at times, may exceed federally insured limits. At December 31, 2011 and January 1, 2011 the Company exceeded the insured limit by $187.5 million and $125.4 million, respectively. Financial instruments which potentially expose the Company to concentrations of credit risk consist of accounts receivable. Management believes its credit policies are prudent and reflect normal industry terms and business risk. At December 31, 2011 four customers accounted for a total of 63% of the Company’s accounts receivable balance, each of which was greater than 10% of the balance. Two of the customers accounting for 29% of the Company’s accounts receivable balance secured their balance with guaranteed letters of credit. At January 1, 2011, two customers accounted for 22% and 19% of the Company’s accounts receivable balance. The customer accounting for 22% of the Company’s accounts receivable balance secured their balance with guaranteed letters of credit. For the years ended December 31, 2011, January 1, 2011, and January 2, 2010, revenue from U.S. federal government orders, contracts and subcontracts, represented 36.1%, 38.4% and 36.9% of total revenue, respectively. For the fiscal year ended December 31, 2011 and January 1, 2011, the Company generated 9.4% and 17.4%, respectively of total revenue from The Boeing Company as a subcontractor under U.S. federal government contracts. For the fiscal year ended December 31, 2011, the Company generated 23.6% of total revenue from two of its international distributors of home robots products. Foreign Currency Forward Contracts The Company periodically enters into foreign currency forward contracts to sell foreign currencies for United States dollars. The Company’s objective in entering into these contracts was to reduce foreign currency exposure to appreciation or depreciation in the value of its foreign currency based accounts receivable balances by partially offsetting a portion of such exposure with gains or losses on the forward contracts. These foreign currency contracts did not qualify for hedge accounting. Accordingly, the foreign currency forward contracts were marked-to-market and recorded at fair value with unrealized gains and losses reported along with foreign currency gains or losses in the caption “other income (expense), net” on the Company’s consolidated statements of income. As of December 31, 2011, the Company did not have any foreign currency forward contracts. Stock-Based Compensation The Company accounts for stock-based compensation through recognition of the fair value of the stock-based compensation as a charge against earnings. Stock-based compensation cost for stock options is estimated at the grant date based on each option’s fair-value as calculated by the Black-Scholes option-pricing model. Stock-based compensation cost for restricted stock awards and restricted stock units is measured based on the closing fair market value of the Company’s common stock on the date of grant. The Company recognizes stock-based compensation cost as expense ratably on a straight-line basis over the requisite service period, net of estimated forfeitures. Advertising Expense The Company expenses advertising costs as they are incurred. During the years ended December 31, 2011, January 1, 2011 and January 2, 2010 advertising expense totaled $20.4 million, $13.8 million and $7.0 million, respectively. Net Income Per Share The following table presents the calculation of both basic and diluted net income per share:
Potentially dilutive securities representing approximately 0.4 million, 1.0 million and 2.3 million shares of common stock for the fiscal years ended December 31, 2011, January 1, 2011 and January 2, 2010, respectively, were excluded from the computation of diluted earnings per share for these periods because their effect would have been antidilutive.
Income Taxes The Company is subject to taxation in the United States and various states and foreign jurisdictions. The statute of limitations for assessment by the IRS and state tax authorities is closed for fiscal years prior to December 31, 2008, although carryforward attributes that were generated prior to fiscal year 2008 may still be adjusted upon examination by the IRS or state tax authorities if they either have been or will be used in a future period. The IRS is currently beginning to examine the Company’s tax returns for the years 2009 and 2010. Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are provided if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company monitors the realization of its deferred tax assets based on changes in circumstances, for example recurring periods of income for tax purposes following historical periods of cumulative losses or changes in tax laws or regulations. The Company’s income tax provisions and its assessment of the ability to realize its deferred tax assets involve significant judgments and estimates. In fiscal 2007, the Company completed an analysis of historical and projected future profitability which resulted in the full release of the valuation allowance relating to federal deferred tax assets. In fiscal 2010, based on recent and expected increased future profitability, the Company released its valuation allowance relating to state deferred tax assets. At December 31, 2011, the Company has total deferred tax assets of $21.5 million with no valuation allowance. Comprehensive Income Accumulated other comprehensive income includes unrealized gains and losses on certain investments. The differences between net income and comprehensive income were related to unrealized gains (losses) on investments, net of tax. Fair Value Measurements The authoritative guidance for fair value establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company’s assets measured at fair value on a recurring basis at December 31, 2011, were as follows:
The bond investments are valued based on observable market values as of the Company’s reporting date and are included in Level 2. The bond investments are recorded at fair value and marked-to-market at the end of each reporting period and realized and unrealized gains and losses are included in comprehensive income for that period. The fair value of the Company’s bond investments are included in short term investments in its consolidated balance sheet. The Company’s assets measured at fair value on a recurring basis at January 1, 2011, were as follows:
The bond investments are valued based on observable market values as of the Company’s reporting date and is included in Level 2. The bond investment is recorded at fair value and marked-to-market at the end of each reporting period and realized and unrealized gains and losses are included in comprehensive income for that period. The fair value of the Company’s bond investment is included in short term investments in its consolidated balance sheet. Recent Accounting Pronouncements In May 2011, the FASB issued amended guidance on fair value measurement and related disclosures. The new guidance clarifies the concepts applicable for fair value measurement of non-financial assets and requires the disclosure of quantitative information about the unobservable inputs used in a fair value measurement. This guidance will be effective for reporting periods beginning after December 15, 2011, and will be applied prospectively. The Company does not anticipate a material impact on its consolidated financial statements as a result of the adoption of this amended guidance. In June 2011, the FASB amended its accounting guidance on the presentation of other comprehensive income (OCI) in an entity’s financial statements. The amended guidance eliminates the option to present the components of OCI as part of the statement of changes in shareholders equity and provides two options for presenting OCI: in a statement included in the income statement or in a separate statement immediately following the income statement. The amendments do not change the guidance for the items that have to be reported in OCI or when an item of OCI has to be moved into net income. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The Company does not anticipate that its adoption of this guidance will have a material impact on its consolidated results. In September 2011, the FASB issued updated guidance on the periodic testing of goodwill for impairment. The updated guidance gives companies the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The amendment is intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a qualitative assessment to determine whether further impairment testing is necessary. The updated accounting guidance is effective for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company elected to adopt the updated guidance in 2011. The adoption of this guidance did not impact its consolidated financial statements. 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.

Goodwill and Intangible assets are the result of the acquisition of Nekton Research, LLC (“Nekton”), See Note 13 to the Consolidated Financial Statements for a more detailed discussion of the Goodwill and intangible assets, net. In November 2007, the Company recorded an investment of $2.5 million in a series of preferred stock of Advanced Scientific Concepts, Inc. This investment is accounted for at cost. The Company regularly monitors this investment to determine if facts and circumstances have changed in a manner that would require a change in accounting methodology. Additionally, the Company regularly evaluates whether or not 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. Since the Company believes the fair value of its investment is greater than the carrying value of its investment, it has not impaired this investment.

| Stock Options Plans and Stock-Based Compensation |
The Company has options outstanding under three stock incentive plans: the 1994 Stock Option Plan (the “1994 Plan”), the 2004 Stock Option and Incentive Plan (the “2004 Plan”) and the 2005 Stock Option and Incentive Plan (the “2005 Plan” and together with the 1994 Plan and the 2004 Plan, the “Plans”). The 2005 Plan is the only one of the three 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 as a result of their expiration, cancellation or termination are automatically made available for issuance under the 2005 Plan. Eligibility for incentive stock options is limited to those individuals whose employment status would qualify them for the tax treatment associated with incentive stock options in accordance with the Internal Revenue Code of 1986, as amended. As of December 31, 2011, there were 2,695,397 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. 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 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 $0.0 million, $0.1 million and $0.2 million for the fiscal years ended December 31, 2011, January 1, 2011 and January 2, 2010, respectively. The Company recognized $5.2 million of stock-based compensation expense during the fiscal year ended December 31, 2011 for stock options granted subsequent to the Company’s initial filing of its Form S-1 with the SEC. The unamortized fair value as of December 31, 2011 associated with these grants was $11.0 million with a weighted-average remaining recognition period of 2.39 years. On May 29, 2009, the Company completed a one-time stock option exchange program as approved by its stockholders on May 28, 2009. In accordance with the terms and conditions of the stock option exchange program, the Company issued new options to purchase an aggregate of 310,607 shares of the Company’s common stock in exchange for the cancellation of options to purchase an aggregate of 678,850 of the Company’s common stock. The exchange ratios were designed to result in the fair value, for accounting purposes, of the new options being approximately equal to the fair value of the exchanged eligible options to ensure the Company minimized any additional compensation expense in connection with the stock option exchange program. The Company incurred no additional compensation expense in connection with the program.
The fair value of each option grant for the fiscal years ended December 31, 2011, January 1, 2011 and January 2, 2010 (excluding the new options issued in conjunction with the stock option exchange program described in the preceding paragraph for which no incremental compensation expense was realized) was computed on the grant date using the Black-Scholes option-pricing model with the following assumptions:
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 the relevant authoritative guidance, 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, prior to 2010, the Company performed an analysis that included company specific historical data combined with data of several peer companies with similar expected option lives to develop expected volatility assumptions. During 2010, the Company began to rely solely on company specific historical data for purposes of establishing expected volatility. Based upon the above assumptions, the weighted average fair value of each stock option granted for the fiscal years ended December 31, 2011, January 1, 2011 and January 2, 2010 (excluding the new options issued in conjunction with the stock option exchange program for which no incremental compensation expense was realized) was $16.55, $8.24 and $4.91, respectively.
The table below summarizes stock option plan activity:
During fiscal years 2011, 2010, and 2009, the total intrinsic value of stock options exercised was $25.4 million, $7.5 million and $2.0 million, respectively. No amounts relating to stock-based compensation have been capitalized.
The following table summarizes information about stock options outstanding at December 31, 2011:
The table below summarizes activity relating to restricted stock awards:
During the fiscal year ended December 31, 2011, the Company recognized $0.0 million of stock based compensation expense associated with restricted stock awards. As of December 31, 2011, the unamortized fair value of all restricted stock awards was $0.0 million. The table below summarizes activity relating to restricted stock units:
During the fiscal year ended December 31, 2011, the Company recognized $3.6 million of stock based compensation expense associated with restricted stock units. As of December 31, 2011, January 1, 2011 and January 2, 2010 the unamortized fair value of all restricted stock units was $11.7 million, $7.6 million and $3.2 million, respectively. The Company expects to recognize associated stock-based compensation expense of $3.9 million, $3.5 million, $3.1 million and $1.2 million in 2012, 2013, 2014 and 2015, respectively. The following includes significant activity that is included in the stock option activity and restricted stock activity tables above: On December 30, 2011, in connection with the appointment of a new member to its board of directors, the Company granted 7,370 restricted stock units. Additionally on December 30, 2011, in connection with the commencement of his employment, the Company granted one employee stock options exercisable for an aggregate of 15,000 shares of the Company’s common stock and 7,500 restricted stock units. The above stock options have a per share exercise price of $29.85, the closing price of the Company’s common stock on NASDAQ on December 30, 2011. The stock options will vest 25% on the first anniversary of the grant date and quarterly over the following three years, and the restricted stock units will vest 25% on each anniversary of the grant date. On September 30, 2011, the Company granted to certain employees an annual merit grant totaling 43,400 restricted stock units. These restricted stock units will vest 25% on each anniversary of the grant date. On July 1, 2011, the Company granted one member of the Board of Directors 6,118 restricted stock units in connection with the commencement of her appointment. These restricted stock units will vest 25% on each anniversary of the grant date. Also on July 1, 2011, the Company granted each of its nine non-employee board members 3,059 restricted stock units. These restricted stock units will vest 100% on the first anniversary of the grant.
On April 1, 2011, in connection with the commencement of their employment, the Company granted five employees stock options exercisable for an aggregate of 40,000 shares of the Company’s common stock and 19,000 restricted stock units. Additionally, on April 1, 2011, the Company granted to certain employees, including executive officers, an annual merit grant of stock options totaling 281,150 shares of the Company’s common stock and 141,575 restricted stock units. Each of the above stock options have a per share exercise price of $33.48, the closing price of the Company’s common stock on NASDAQ on April 1, 2011. The stock options will vest 25% on the first anniversary of the grant date and quarterly thereafter over the following three years. The restricted stock units will vest 25% on each anniversary of the grant date.

| Income Taxes |
The components of income tax expense were as follows:
An immaterial provision has been made for deferred taxes on undistributed earnings of non-U.S. subsidiaries that the Company expects to distribute in 2012. For the remaining undistributed earnings of non-U.S. subsidiaries, no provision has been made for deferred taxes as these earnings have been indefinitely reinvested. Determination of the amount of unrecognized deferred tax liability on these undistributed earnings is not practicable. As of December 31, 2011, a deferred tax liability has not been established for approximately $0.1 million of cumulative undistributed earnings of non-U.S. subsidiaries, as the Company plans to keep these amounts permanently reinvested overseas. During the quarter ending January 2, 2010, the Company recorded an out-of-period adjustment in the income tax provision of $0.2 million to correct an error with respect to the earnings of the Company’s India subsidiary. The Company believes that this adjustment did not have a material impact to its full year 2009 results. In addition, management does not believe the adjustment is material to the amounts reported by the Company in previous periods.
The components of net deferred tax assets were as follows:
In fiscal 2010, based on recent and expected increased future profitability, the Company released its valuation allowance relating to state deferred tax assets. The table below summarizes activity relating to the valuation allowance:
The net deferred tax assets as of December 31, 2011 and January 1, 2011 were $21.5 million and $21.3 million, respectively. As of December 31, 2011, the Company has research and development credits carryforwards available to offset future state taxes of $4.4 million and investment tax credit carryforwards to offset future state taxes of $0.7 million, which expire at various dates from 2012 to 2026. As of January 1, 2011, the Company had research and development credits carryforwards available to offset future state taxes of $2.7 million and investment tax credit carryforwards to offset future state taxes of $0.4 million, which expire at various dates from 2016 to 2025. Under the Internal Revenue Code, certain substantial changes in the Company’s ownership could result in an annual limitation on the amount of these tax carryforwards which can be utilized in future years.
The reconciliation of the expected tax (benefit) expense (computed by applying the federal statutory rate to income before income taxes) to actual tax expense was as follows:
Prior to January 1, 2011, the Company had no material unrecognized tax benefits recorded. A summary of the Company’s adjustments to its uncertain tax position is the current year is as follows:
The Company recognizes interest and penalties related to unrecognized tax benefits in its tax provision. As of December 31, 2011, January 1, 2011 and January 2, 2010, there were no material accrued interest or penalties. We anticipate the settlement of federal tax audits may be finalized within the next twelve months and could result in a decrease in our unrecognized tax benefits of up to $1.0 million. If all of our unrecognized tax benefits as of December 31, 2011 were to become recognizable in the future, we would record a $1.9 million benefit to the income tax provision. We follow the with and without approach for direct and indirect effects of the windfall tax deductions.

Legal On August 17, 2007, the Company filed a lawsuit in Massachusetts Superior Court against Robotic FX, Inc. and Jameel Ahed alleging, among other things, misappropriation of trade secrets and breach of contract, and seeking both injunctive and monetary relief. The case was subsequently removed to the United States District Court for the District of Massachusetts. On November 2, 2007, the court issued a preliminary injunction, and on December 21, 2007 issued a permanent injunction, against Robotic FX, Inc. and Mr. Ahed preventing the sale of products using certain of the Company’s trade secrets, including the Robotic FX Negotiator product. In addition, on August 17, 2007, the Company filed a lawsuit in the United States District Court for the Northern District of Alabama against Robotic FX, Inc. alleging willful infringement of two patents owned by the Company, and seeking both injunctive and monetary relief. On December 21, 2007, the court entered a judgment that Robotic FX, Inc. knowingly infringed on both asserted patents. In a related settlement, Robotic FX, Inc. was dissolved and certain residual assets were retained by the Company at its election. Mr. Ahed is prohibited from participating in competitive activities in the robotics industry for five years. The cumulative litigation and settlement-related expenditures associated with this dispute are expected to total approximately $3.0 million, including an obligation to make cash payments up to $0.4 million through 2012, contingent upon Mr. Ahed and Robotic FX, Inc. continuing to meet obligations pursuant to various agreements, including but not limited to certain non-competition provisions. The Company paid $0.1 million to Mr. Ahed during the fiscal year ended December 31, 2011. These contingent payments will continue to be expensed, when and if earned. Lease Obligations The Company leases its facilities. Rental expense under operating leases for fiscal 2011, 2010 and 2009 amounted to $4.1 million, $3.7 million, and $3.9 million, respectively. Future minimum rental payments under operating leases were as follows as of December 31, 2011:
Guarantees and Indemnification Obligations The Company enters into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, the Company indemnifies and agrees to reimburse the indemnified party for losses incurred by the indemnified party, generally the Company’s customers, in connection with any patent, copyright, trade secret or other proprietary right infringement claim by any third party with respect to the Company’s software. The term of these indemnification agreements is generally perpetual any time after execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal. Accordingly, the Company has no liabilities recorded for these agreements as of December 31, 2011 and January 1, 2011, respectively.
Government Contract Contingencies Several of the Company’s prime contracts with the U.S. federal government do not contain a limitation of liability provision, creating a risk of responsibility for direct and consequential damages. Several subcontracts with prime contractors hold the prime contractor harmless against liability that stems from our work and do not contain a limitation of liability. These provisions could cause substantial liability for the Company. In addition, the Company is subject to audits by the U.S. federal government as part of routine audits of government contracts. As part of an audit, these agencies may review the Company’s performance on contracts, cost structures and compliance with applicable laws, regulations and standards. If any of its costs are found to be allocated improperly to a specific contract, the costs may not be reimbursed and any costs already reimbursed for such contract may have to be refunded. Accordingly, an audit could result in a material adjustment to our revenue and results of operations. Annually, the Company submits final indirect billing rates to DCMA based upon actual costs incurred throughout the year. These final billing rates are subject to audit by DCAA. As of December 31, 2011, fiscal years 2007, 2008, 2009, 2010 and 2011 are open for audit by DCAA. Warranty The Company provides warranties on most products and has established a reserve for warranty based on identified warranty costs. The reserve is included as part of accrued expenses (Note 6) in the accompanying consolidated balance sheets. Activity related to the warranty accrual was as follows:
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.

| Employee Benefits |
The Company sponsors a retirement plan under Section 401(k) of the Internal Revenue Code (the “Retirement Plan”). All Company employees, with the exception of temporary, contract and international employees are eligible to participate in the Retirement Plan after satisfying age and length of service requirements prescribed by the plan. Under the Retirement Plan, employees may make tax- deferred contributions, and the Company, at its sole discretion, and subject to the limits prescribed by the IRS, may make either a nonelective contribution on behalf of all eligible employees or a matching contribution on behalf of all plan participants. The Company elected to make a matching contribution of approximately $1.7 million, $1.5 million and $1.2 million for the plan years ended December 31, 2011, January 1, 2011 and January 2, 2010 (“Plan-Year 2011,” “Plan-Year 2010” and “Plan-Year 2009”), respectively. The employer contribution represents a matching contribution at a rate of 50% of each employee’s first six percent contribution. Accordingly, each employee participating during Plan-Year 2011, Plan-Year 2010 and Plan-Year 2009 is entitled up to a maximum of three percent of his or her eligible annual payroll. The employer matching contribution for Plan-Year 2011 is included in accrued compensation.

| Goodwill and other intangible assets |
The carrying amount of the goodwill at December 31, 2011 of $7.9 million is from the acquisition of Nekton completed in September 2008. In the fourth quarter of 2011, the Company completed its annual goodwill impairment test and did not identify any goodwill impairment. 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 estimated economic benefits of the intangible assets are expected to be utilized. Intangible assets at December 31, 2011 and January 1, 2011 consisted of the following:
Amortization expense related to acquired intangible assets was $903,000 and $475,000 for the fiscal years ended December 31, 2011 and January 1, 2011. The estimated future amortization expense related to current intangible assets in each of the five succeeding fiscal years is expected to be as follows:

| Industry Segment, Geographic Information and Significant Customers |
The Company operates in two reportable segments, the home robots division and the government and industrial robots 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 division 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 division includes mobile robots used in the maintenance of domestic households. Government and Industrial Robots The Company’s government and industrial robots division offers products through a small U.S. government-focused sales force, while products are 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 government and industrial robots are used by various U.S. and foreign governments, primarily for reconnaissance and bomb disposal missions. The table below presents segment information about revenue, cost of revenue, gross margin and income before income taxes:

| Summary of Significant Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Basis of Presentation |
Basis of Presentation The accompanying consolidated financial statements include those of iRobot and its subsidiaries, after elimination of all intercompany accounts and transactions. In addition, certain prior year amounts have been reclassified to conform with the current year presentation. iRobot has prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Use of Estimates |
Use of Estimates The preparation of these financial statements in conformity with accounting principles generally accepted in the United States requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates these estimates and judgments, including those related to revenue recognition, sales returns, bad debts, warranty claims, inventory reserves, valuation of investments, assumptions used in valuing stock-based compensation instruments and income taxes. The Company bases these estimates on historical and anticipated results, and trends and on various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results may differ from the Company’s estimates. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fiscal Year-End |
Fiscal Year-End The Company operates and reports using a 52-53 week fiscal year ending on the Saturday closest to December 31. Accordingly, the Company’s fiscal quarters will end on the Saturday that falls closest to the last day of the third month of each quarter. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Cash and Cash Equivalents |
Cash and Cash Equivalents The Company considers all highly liquid investments with an original or remaining maturity of three months or less at the time of purchase to be cash equivalents. The Company invests its excess cash primarily in money market funds or savings accounts of major financial institutions. Accordingly, its cash equivalents are subject to minimal credit and market risk. At December 31, 2011 and January 1, 2011, cash equivalents were comprised of money market funds totaling $117.2 million and $5.1 million, respectively. These cash equivalents are carried at cost, which approximates fair value. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Short Term Investments |
Short Term Investments The Company’s investments are classified as available-for-sale and are recorded at fair value with any unrealized gain or loss recorded as an element of stockholders’ equity. The fair value of investments is determined based on quoted market prices at the reporting date for those instruments. As of December 31, 2011 and January 1, 2011, investments consisted of:
As of December 31, 2011, the Company’s investments had maturity dates ranging from October 2012 to November 2014. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Revenue Recognition |
Revenue Recognition The Company derives its revenue from product sales, government research and development contracts, and commercial research and development contracts. The Company sells products directly to customers and indirectly through resellers and distributors. The Company recognizes revenue from sales of home robots under the terms of the customer agreement upon transfer of title and risk of loss to the customer, net of estimated returns, provided that collection is determined to be reasonably assured and no significant obligations remain. Sales to domestic resellers are typically subject to agreements allowing for limited rights of return, rebates and price protection. Accordingly, the Company reduces revenue for its estimates of liabilities for these rights of return at the time the related sale is recorded. The Company makes an estimate of sales returns for products sold by domestic resellers directly based on historical returns experience and other relevant data. The Company’s international distributor agreements do not currently allow for product returns and, as a result, no reserve for returns is established for this group of customers. The Company has aggregated and analyzed historical returns from domestic resellers and end users which form the basis of its estimate of future sales returns by resellers or end users. When a right of return exists, the provision for these estimated returns is recorded as a reduction of revenue at the time that the related revenue is recorded. If actual returns differ significantly from its estimates, such differences could have a material impact on the Company’s results of operations for the period in which the returns become known. The estimates for returns are adjusted periodically based upon historical rates of returns. The estimates and reserve for rebates and price protection are based on specific programs, expected usage and historical experience. Actual results could differ from these estimates. Under cost-plus-fixed-fee (“CPFF”) type contracts, the Company recognizes revenue based on costs incurred plus a pro rata portion of the total fixed fee. Costs incurred include labor and material that are directly associated with individual CPFF contracts plus indirect overhead and general and administrative type costs based upon billing rates submitted by the Company to the Defense Contract Management Agency (“DCMA”). Annually, the Company submits final indirect billing rates to DCMA based upon actual costs incurred throughout the year. In the situation where the Company’s final actual billing rates are greater than the provisional rates currently in effect, the Company records a cumulative revenue adjustment in the period in which the rate differential is collected from the customer. These final billing rates are subject to audit by the Defense Contract Audit Agency (“DCAA”), which can occur several years after the final billing rates are submitted and may result in material adjustments to revenue recognized based on estimated final billing rates. As of December 31, 2011, fiscal years 2007, 2008, 2009, 2010 and 2011 are open for audit by DCAA. In the situation where the Company’s anticipated actual billing rates will be lower than the provisional rates currently in effect, the Company records a cumulative revenue adjustment in the period in which the rate differential is identified. Revenue on firm fixed price (“FFP”) contracts is recognized using the percentage-of-completion method. For government product FFP contracts, revenue is recognized as the product is shipped or in accordance with the contract terms. Costs and estimated gross margins on contracts are recorded as revenue as work is performed based on the percentage that incurred costs compare to estimated total costs utilizing the most recent estimates of costs and funding. Changes in job performance, job conditions, and estimated profitability, including those arising from final contract settlements and government audits, may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Since many contracts extend over a long period of time, revisions in cost and funding estimates during the progress of work have the effect of adjusting earnings applicable to past performance in the current period. When the current contract estimate indicates a loss, a provision is made for the total anticipated loss in the current period. Revenue earned in excess of billings, if any, is recorded as unbilled revenue. Billings in excess of revenue earned, if any, are recorded as deferred revenue. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Allowance for Doubtful Accounts |
Allowance for Doubtful Accounts The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivable that may not be collected. The allowance is based upon an assessment of customer creditworthiness, historical payment experience and the age of outstanding receivables. Activity related to the allowance for doubtful accounts was as follows:
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Inventory |
Inventory Inventory is stated at the lower of cost or net realizable value with cost being determined using the first-in, first-out (FIFO) method. The Company maintains a reserve for inventory items to provide for an estimated amount of excess or obsolete inventory. Activity related to the inventory reserve was as follows:
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Property and Equipment |
Property and Equipment Property and equipment are recorded at cost and consist primarily of computer equipment, leasehold improvements, business applications software and machinery. Depreciation is computed using the straight-line method over the estimated useful lives as follows:
Expenditures for additions, renewals and betterments of plant and equipment are capitalized. Expenditures for repairs and maintenance are charged to expense as incurred. As assets are retired or sold, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is credited or charged to operations. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Long-Lived Assets Including Purchased Intangible Assets |
Long-Lived Assets, including Purchased Intangible Assets The Company periodically evaluates the recoverability of long-lived assets, including other purchased intangible assets whenever events and changes in circumstances, such as reductions in demand or significant economic slowdowns in the industry, indicate that the carrying amount of an asset may not be fully recoverable. When indicators of impairment are present, the carrying values of the asset group are evaluated in relation to the future undiscounted cash flows of the underlying business. The net book value of the underlying asset is adjusted to fair value if the sum of the expected discounted cash flows is less than book value. Fair values are based on estimates of market prices and assumptions concerning the amount and timing of estimated future cash flows and assumed discount rates, reflecting varying degrees of perceived risk. There were no impairment charges recorded during any of the periods presented. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Goodwill |
Goodwill Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. The Company evaluates goodwill for impairment at the reporting unit level (operating segment or one level below an operating segment) annually or more frequently if the Company believes indicators of impairment exist. In 2011, the Company early adopted the new provisions issued by the Financial Accounting Standards Board (“FASB”) that intended to simplify goodwill impairment testing. The updated guidance permits the Company to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then a two-step goodwill impairment test is performed. The first step of the impairment test involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. If the carrying amount of a reporting unit exceeds the reporting unit’s fair value, the Company performs the second step of the goodwill impairment test to determine the amount of impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Research and Development |
Research and Development Costs incurred in the research and development of the Company’s products, classified as cost of contract and research and development, are expensed as incurred. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Internal Use Software |
Internal Use Software The Company capitalizes costs associated with the development and implementation of software obtained for internal use. At December 31, 2011 and January 1, 2011, the Company had $8.3 million and $5.8 million respectively, of costs related to enterprise-wide software included in fixed assets. Capitalized costs are being amortized over the assets’ estimated useful lives. The Company has recorded $0.9 million, $0.9 million and $0.9 million of amortization expense for the years ended December 31, 2011, January 1, 2011 and January 2, 2010, respectively. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Concentration of Credit Risk and Significant Customers |
Concentration of Credit Risk and Significant Customers The Company maintains its cash in bank deposit accounts at high quality financial institutions. The individual balances, at times, may exceed federally insured limits. At December 31, 2011 and January 1, 2011 the Company exceeded the insured limit by $187.5 million and $125.4 million, respectively. Financial instruments which potentially expose the Company to concentrations of credit risk consist of accounts receivable. Management believes its credit policies are prudent and reflect normal industry terms and business risk. At December 31, 2011 four customers accounted for a total of 63% of the Company’s accounts receivable balance, each of which was greater than 10% of the balance. Two of the customers accounting for 29% of the Company’s accounts receivable balance secured their balance with guaranteed letters of credit. At January 1, 2011, two customers accounted for 22% and 19% of the Company’s accounts receivable balance. The customer accounting for 22% of the Company’s accounts receivable balance secured their balance with guaranteed letters of credit. For the years ended December 31, 2011, January 1, 2011, and January 2, 2010, revenue from U.S. federal government orders, contracts and subcontracts, represented 36.1%, 38.4% and 36.9% of total revenue, respectively. For the fiscal year ended December 31, 2011 and January 1, 2011, the Company generated 9.4% and 17.4%, respectively of total revenue from The Boeing Company as a subcontractor under U.S. federal government contracts. For the fiscal year ended December 31, 2011, the Company generated 23.6% of total revenue from two of its international distributors of home robots products. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Foreign Currency Forward Contracts |
Foreign Currency Forward Contracts The Company periodically enters into foreign currency forward contracts to sell foreign currencies for United States dollars. The Company’s objective in entering into these contracts was to reduce foreign currency exposure to appreciation or depreciation in the value of its foreign currency based accounts receivable balances by partially offsetting a portion of such exposure with gains or losses on the forward contracts. These foreign currency contracts did not qualify for hedge accounting. Accordingly, the foreign currency forward contracts were marked-to-market and recorded at fair value with unrealized gains and losses reported along with foreign currency gains or losses in the caption “other income (expense), net” on the Company’s consolidated statements of income. As of December 31, 2011, the Company did not have any foreign currency forward contracts. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Stock-Based Compensation |
Stock-Based Compensation The Company accounts for stock-based compensation through recognition of the fair value of the stock-based compensation as a charge against earnings. Stock-based compensation cost for stock options is estimated at the grant date based on each option’s fair-value as calculated by the Black-Scholes option-pricing model. Stock-based compensation cost for restricted stock awards and restricted stock units is measured based on the closing fair market value of the Company’s common stock on the date of grant. The Company recognizes stock-based compensation cost as expense ratably on a straight-line basis over the requisite service period, net of estimated forfeitures. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Advertising Expense |
Advertising Expense The Company expenses advertising costs as they are incurred. During the years ended December 31, 2011, January 1, 2011 and January 2, 2010 advertising expense totaled $20.4 million, $13.8 million and $7.0 million, respectively. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Net Income Per Share |
Net Income Per Share The following table presents the calculation of both basic and diluted net income per share:
Potentially dilutive securities representing approximately 0.4 million, 1.0 million and 2.3 million shares of common stock for the fiscal years ended December 31, 2011, January 1, 2011 and January 2, 2010, respectively, were excluded from the computation of diluted earnings per share for these periods because their effect would have been antidilutive. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Income Taxes |
Income Taxes The Company is subject to taxation in the United States and various states and foreign jurisdictions. The statute of limitations for assessment by the IRS and state tax authorities is closed for fiscal years prior to December 31, 2008, although carryforward attributes that were generated prior to fiscal year 2008 may still be adjusted upon examination by the IRS or state tax authorities if they either have been or will be used in a future period. The IRS is currently beginning to examine the Company’s tax returns for the years 2009 and 2010. Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are provided if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company monitors the realization of its deferred tax assets based on changes in circumstances, for example recurring periods of income for tax purposes following historical periods of cumulative losses or changes in tax laws or regulations. The Company’s income tax provisions and its assessment of the ability to realize its deferred tax assets involve significant judgments and estimates. In fiscal 2007, the Company completed an analysis of historical and projected future profitability which resulted in the full release of the valuation allowance relating to federal deferred tax assets. In fiscal 2010, based on recent and expected increased future profitability, the Company released its valuation allowance relating to state deferred tax assets. At December 31, 2011, the Company has total deferred tax assets of $21.5 million with no valuation allowance. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Comprehensive Income |
Comprehensive Income Accumulated other comprehensive income includes unrealized gains and losses on certain investments. The differences between net income and comprehensive income were related to unrealized gains (losses) on investments, net of tax. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair Value Measurements |
Fair Value Measurements The authoritative guidance for fair value establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company’s assets measured at fair value on a recurring basis at December 31, 2011, were as follows:
The bond investments are valued based on observable market values as of the Company’s reporting date and are included in Level 2. The bond investments are recorded at fair value and marked-to-market at the end of each reporting period and realized and unrealized gains and losses are included in comprehensive income for that period. The fair value of the Company’s bond investments are included in short term investments in its consolidated balance sheet. The Company’s assets measured at fair value on a recurring basis at January 1, 2011, were as follows:
The bond investments are valued based on observable market values as of the Company’s reporting date and is included in Level 2. The bond investment is recorded at fair value and marked-to-market at the end of each reporting period and realized and unrealized gains and losses are included in comprehensive income for that period. The fair value of the Company’s bond investment is included in short term investments in its consolidated balance sheet. |

| Recent Accounting Pronouncements |
Recent Accounting Pronouncements In May 2011, the FASB issued amended guidance on fair value measurement and related disclosures. The new guidance clarifies the concepts applicable for fair value measurement of non-financial assets and requires the disclosure of quantitative information about the unobservable inputs used in a fair value measurement. This guidance will be effective for reporting periods beginning after December 15, 2011, and will be applied prospectively. The Company does not anticipate a material impact on its consolidated financial statements as a result of the adoption of this amended guidance. In June 2011, the FASB amended its accounting guidance on the presentation of other comprehensive income (OCI) in an entity’s financial statements. The amended guidance eliminates the option to present the components of OCI as part of the statement of changes in shareholders equity and provides two options for presenting OCI: in a statement included in the income statement or in a separate statement immediately following the income statement. The amendments do not change the guidance for the items that have to be reported in OCI or when an item of OCI has to be moved into net income. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The Company does not anticipate that its adoption of this guidance will have a material impact on its consolidated results. In September 2011, the FASB issued updated guidance on the periodic testing of goodwill for impairment. The updated guidance gives companies the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The amendment is intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a qualitative assessment to determine whether further impairment testing is necessary. The updated accounting guidance is effective for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company elected to adopt the updated guidance in 2011. The adoption of this guidance did not impact its consolidated financial statements. 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. |

- Definition
Investments in debt and equity securities which are categorized neither as trading securities nor held-to-maturity securities and which are intended be sold or mature within one year from the balance sheet date or the normal operating cycle, whichever is longer. Such securities are reported at fair value; unrealized gains (losses) related to Available-for-sale Securities are excluded from earnings and reported in a separate component of shareholders' equity (other comprehensive income), unless the Available-for-sale security is designated as a hedge or is determined to have had an other than temporary decline in fair value below its amortized cost basis. All or a portion of the unrealized holding gain (loss) of an Available-for-sale security that is designated as being hedged in a fair value hedge is recognized in earnings during the period of the hedge, as are other than temporary declines in fair value below the cost basis for investments in equity securities and debt securities that an entity intends to sell or it is more likely than not that it will be required to sell before the recovery of its amortized cost basis. Other than temporary declines in fair value below the cost basis for debt securities categorized as Available-for-sale that an entity does not intend to sell and for which it is not more likely than not that the entity will be required to sell before the recovery of its amortized cost basis are bifurcated into credit losses and losses related to all other factors. Other than temporary declines in fair value below cost basis related to credit losses are recognized in earnings, and losses related to all other factors are recognized in other comprehensive income.
