Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation and Foreign Currency Translation The accompanying consolidated financial statements include those of iRobot and its subsidiaries, after elimination of all intercompany balances and transactions. iRobot has prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP"). For the Company's subsidiaries that transact in a functional currency other than the U.S. dollar, assets and liabilities are translated into U.S. dollars at period-end foreign exchange rates. Revenues and expenses are translated into U.S. dollars at the average foreign exchange rates for the period. Translation adjustments are excluded from the determination of net income (loss) and are recorded in accumulated other comprehensive income (loss), a separate component of stockholders' equity. 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. As used in the Annual Report on Form 10-K, "fiscal 2022" refers to the 52-week fiscal year ending December 31, 2022, "fiscal 2021" refers to the 52-week fiscal year ended January 1, 2022, and "fiscal 2020" refers to the 53-week fiscal year ended January 2, 2021. Liquidity The accompanying audited consolidated financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the continuity of operations, realization of assets, and liquidation of liabilities in the normal course of business. The Company has a long history of profitable operations, positive operating cash flows and substantial liquidity that was further strengthened during the first year of the COVID-19 pandemic as consumer demand for iRobot's products increased considerably. During fiscal 2022, the Company’s revenue declined 24% from fiscal 2021 primarily due to lower orders from retailers and distributors in the United States and EMEA largely resulting from a decline in consumer sentiment, and resultant spending, driven by high inflation, rising interest rates, rising energy costs, the potential recessionary outlook and geopolitical instability, which was exacerbated by the Russia-Ukraine war. The lower revenue has resulted in operating losses of $240.4 million and operating cash outflows of $90.0 million for the fiscal 2022. As a result, the Company's cash and cash equivalents and short-term investments have declined from $234.5 million as of January 1, 2022 to $117.9 million as of December 31, 2022. As of December 31, 2022, the Company has no outstanding borrowings from its $150.0 million available revolving line of credit which expires on June 30, 2023. On January 17, 2023, the Company entered into a Fourth Amendment (the "Fourth Amendment") to the Credit Agreement which reduces the amount of the facility from $150.0 million to $100.0 million and extends the maturity date of the Credit Agreement from June 30, 2023 to September 17, 2024 (see Note 8 for additional details about its Credit Agreement). Management has considered and assessed its ability to continue as a going concern for the one year from the date that the audited consolidated financial statements are issued. Management’s assessment included the preparation of cash flow forecasts taking into account actions already implemented. Management considered additional actions within its control that it would implement, if necessary, to maintain liquidity and operations in the ordinary course. Management has already undertaken the following actions to improve profitability and operating cash flows and align the organization to the lower revenue level: • During August 2022, the Company initiated a restructuring of its operations designed to better align its cost structure with near-term revenue and cash flow generation, advance key strategic priorities, increase efficiencies and improve its profitability going forward. As part of this August 2022 restructuring, the Company reduced its workforce and terminated approximately 100 employees, which represents 8% of its workforce and eliminated a number of open positions entering the third quarter of 2022. As a follow-on action to the company’s August 2022 restructuring of operations and in anticipation that market conditions will remain challenging into 2023, the Company initiated a new restructuring program at the beginning of February 2023 and reduced its workforce by approximately 85 employees or 7%. In addition to the reduction in force, iRobot’s 2023 operating plan incorporates scaled back working media and other demand-generation activities, limited investment in non-robotic product categories and minimal new hiring plans in 2023. At December 31, 2022, the Company had 1,254 employees. Including the aforementioned reduction in force of 85 employees, the Company has had a total reduction of 203 employees since the end of fiscal 2021. In addition to the reduction of its headcount, the Company signed a sublease agreement for a portion of its headquarter during the fourth quarter of fiscal 2022 and plans to further consolidate its global facilities footprint during fiscal 2023. iRobot currently anticipates that its August 2022 and February 2023 restructuring actions will deliver net cost savings of approximately $42.0 million in 2023, including actions associated with the facilities consolidation. • Inventory has consumed a significant amount of cash and the Company continues to manage its inventory level carefully. As of December 31, 2022, the inventory balance was $285.3 million, or 95 days, a reduction of $133.8 million, or 95 days from the third quarter of fiscal 2022. In 2023, the Company will continue to manage its inventory to a level that aligns with current run rates of the business. As such, iRobot has temporarily reduced robot production since late January 2023 at its contract manufacturing partners in China and Malaysia with plans to increase production in April 2023. While management estimates such actions will be sufficient to allow it to maintain liquidity and its operations in the ordinary course for at least 12 months from the issuance of these financial statements, there can be no assurance the Company will generate sufficient future cash flows from operations due to potential factors, including, but not limited to, further inflation, the continued rising interest rates, ongoing recessionary conditions or continued reduced demand for the Company’s products. If the Company is not successful in increasing demand for its products, or if macroeconomic conditions further constrain consumer demand, the Company may continue to experience adverse impacts to revenue and profitability. Additional actions within the Company’s control to maintain its liquidity and operations include optimizing its production volumes with contract manufacturers by reducing inventory supply forecast for cancellable purchase orders, further reducing discretionary spending in all areas of the business, decreasing working media spending and realigning resources through ongoing attrition without rehiring activity. Should the Company require further funding in the future, there can be no assurance that it will be able to obtain additional debt financing on terms acceptable to the Company, or at all. The consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of these uncertainties. Use of Estimates The preparation of these financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenue and expenses. These estimates and judgments, include but are not limited to, revenue recognition, including performance obligations, standalone selling price, variable consideration and other obligations such as sales incentives and product returns; allowance for credit losses; impairment of goodwill and long-lived assets; valuation of non-marketable equity investments; product warranties; inventory excess and obsolescence; loss contingencies; accounting for stock-based compensation including valuation and assessments of performance-based awards; accounting for income taxes and related valuation allowances. The Company bases its estimates and assumptions on historical experience, market participant fair value considerations, projected future cash flows, current economic conditions, and various other factors that the Company believes are reasonable under the circumstances. Actual results and outcomes may differ from the Company’s estimates and assumptions. Cash and Cash Equivalents The Company considers all highly liquid investments with maturity of three months or less at the time of purchase to be cash and cash equivalents. The Company invests its excess cash primarily in money market funds or demand deposit accounts of major financial institutions. Accordingly, its cash and cash equivalents are subject to minimal credit and market risk. At December 31, 2022 and January 1, 2022, cash and cash equivalents totaled $117.9 million and $201.5 million, respectively. These cash and cash equivalents are carried at cost, which approximates fair value. Short Term Investments The Company's short term investments include marketable equity securities with readily determinable fair value. The fair value of investments is determined based on quoted market prices at the reporting date for those instruments. The change in fair value of the Company's investments in marketable equity securities is recognized as unrealized gains and losses in other (expense) income, net at the end of each reporting period. Investments consisted of the following (in thousands): December 31, January 1, Cost Fair Cost Fair Marketable equity securities $ — $ — $ 23,286 $ 33,044 Total short term investments $ — $ — $ 23,286 $ 33,044 On July 22, 2021, Matterport, Inc. ("Matterport"), of which the Company held non-marketable equity securities, completed a merger with a special purpose acquisition company and began trading on Nasdaq under the symbol "MTTR." Prior to the merger, the Company accounted for the shares in Matterport as equity securities without readily determinable fair value. Upon consummation of the merger, the Company received 1.6 million shares of MTTR. The post merger Matterport shares received were subject to time based contractual sales restrictions which expired in January 2022. These shares were accounted for as marketable equity securities and measured at fair value with unrealized gains and losses recognized in other (expense) income, net at the end of each reporting period. During fiscal 2021, the Company recorded gains of $30.2 million associated with the Matterport investment. During the first quarter of 2022, the Company sold these Matterport shares and received net proceeds of $16.2 million. In addition, the Company received an additional 0.2 million shares of Matterport during the first quarter of 2022 upon achievement of conditions set forth in the merger agreement, and sold these shares during the second quarter of 2022 for net proceeds of $1.2 million. During fiscal 2022, the Company recognized losses of $17.1 million in other (expense) income, net related to the sales of Matterport shares. As of December 31, 2022, the Company did not have any short term investments. On July 1, 2020, Teladoc Health, Inc. ("Teladoc") closed on its previously announced acquisition of InTouch Health, of which the Company held non-marketable equity securities. In exchange for its shares of InTouch Health, the Company received 0.2 million shares of Teladoc and recorded a gain of $38.6 million to other income, net during fiscal 2020. The Teladoc shares received were subject to time based contractual sales restrictions which expired in January 2021. These shares were accounted for as marketable equity securities and measured at fair value with unrealized gains and losses recognized in other (expense) income, net at the end of each reporting period. As a result, the Company entered into an economic hedge in July 2020 to reduce the Company's exposure to stock price fluctuations during the restricted period. During the first quarter of 2021, the Company received net proceeds of $51.5 million related to the sale of Teladoc shares with gross proceeds of $60.1 million, net of settlement payment of $8.6 million for the related economic hedge. Allowance for Credit Losses The Company maintains an allowance for credit losses for accounts receivable using an expected loss model that requires the use of forward-looking information to calculate credit loss estimate. The expected loss methodology is developed through consideration of factors including, but not limited to, historical collection experience, current customer credit ratings, customer concentrations, current and future economic and market conditions and age of the receivable. The Company reviews and adjusts the allowance for credit losses on a quarterly basis. Accounts receivable balances are written off against the allowance when the Company determines that the balances are not recoverable. As of December 31, 2022 and January 1, 2022, the Company had an allowance for credit losses of $4.7 million and $4.6 million, respectively. Bad debt expense recorded in general and administrative expenses in the consolidated statements of operations during fiscal 2022 and 2021 were immaterial. Accounts receivable allowances Allowance for product returns : The Company records an allowance for product returns based on specific terms and conditions included in the customer agreements or based on historical experience and the Company's expectation of future returns. Allowance for other credits and incentives: The Company records an allowance related to customer incentives such as discounts, promotions, price protection and other support programs. The allowance is based on specific terms and conditions included in customer agreements, specific programs and sell-through expectations, historical experience and other factors. Activity related to accounts receivable allowances was as follows (in thousands): Fiscal Year Ended December 31, January 1, January 2, Allowance for product returns Balance at beginning of period $ 56,839 $ 64,343 $ 55,191 Provision 41,969 61,014 68,028 Deduction (49,657) (68,518) (58,876) Balance at end of period $ 49,151 $ 56,839 $ 64,343 Allowance for other credits and incentives Balance at beginning of period $ 101,606 $ 142,173 $ 134,046 Provision 269,187 267,821 285,139 Deduction (264,274) (308,388) (277,012) Balance at end of period $ 106,519 $ 101,606 $ 142,173 Inventory Inventory primarily consists of finished goods and, to a lesser extent, components, which are purchased from contract manufacturers. Inventory is stated at the lower of cost or net realizable value with cost being determined using the standard cost method, which approximates actual costs determined on the first-in, first-out basis. Inventory costs primarily consist of materials, inbound freight, import duties, tariffs, and other handling fees. The Company writes down its inventory for estimated obsolescence or excess inventory based upon assumptions around market conditions and estimates of future demand. Net realizable value is the estimated selling price less estimated costs of completion, disposal and transportation. Adjustments to reduce inventory to net realizable value are recognized in cost of revenue and have not been significant for the periods presented. Tariff Refunds In April 2020, the Company was granted a temporary exclusion from Section 301 List 3 tariffs by the United States Trade Representative ("USTR"). This exclusion, as extended in August 2020, eliminated the 25% tariff on Roomba products imported from China until December 31, 2020 and entitled the Company to a refund of approximately $57.0 million in tariffs paid since the date the Section 301 List 3 tariffs were imposed. The Company recognized a benefit of $36.5 million from tariff refund during fiscal 2020. In March 2022, the Section 301 List 3 Tariff Exclusion was reinstated, which eliminated the 25% tariff on Roomba products imported from China beginning on October 12, 2021 and continuing until December 31, 2022. This exclusion, which was subsequently extended until September 30, 2023 entitled the Company to a refund of approximately $32.0 million in tariffs paid. During fiscal 2022, the Company recognized a benefit of $11.7 million from tariff refunds as reduction to cost of product revenue related to tariffs paid on products imported after October 12, 2021 and sold during fiscal 2021. As of December 31, 2022, the Company had received $26.8 million of the tariff refund and the outstanding refund receivable of $5.2 million is recorded in other current assets on the consolidated balance sheet. Property and Equipment Property and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives as follows: Estimated Useful Life Computer and equipment 2-5 years Furniture and fixtures 5 Machinery and tooling 2-5 Business applications software 3-7 Leasehold improvements Lesser of economic benefit period or term of lease Expenditures for additions and improvements that extend the useful lives of property and equipment are capitalized. Repairs, maintenance costs and losses associated with disposals or retirements are charged to expense as incurred. Capitalization of Cloud Computing Arrangements The Company incurs costs to implement cloud computing arrangements that are hosted by third-party vendors. Beginning in fiscal 2020, and continuing through fiscal 2022, the Company began investing and implementing various new direct-to-consumer and marketing technology and tools. Implementation costs incurred during the application development stage are capitalized until the software is ready for its intended use. The costs are then amortized on a straight-line basis over the term of the associated hosting arrangement and are recognized as an operating expense within the consolidated statements of operations. During fiscal 2022 and 2021, the Company recorded amortization expenses of $1.8 million and $0.6 million, respectively, for these implementation costs. Capitalized costs were $7.3 million and $7.4 million as of December 31, 2022 and January 1, 2022, respectively, and are reported as a component of other assets on the Company's consolidated balance sheets. Business Combinations The Company allocates the purchase price of each acquisition to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values as of the date of acquisition. Goodwill is measured as the excess of the purchase price over the value of net identified assets acquired. While the Company uses its best estimates and assumptions to accurately value assets acquired, liabilities assumed, and contingent consideration, where applicable, at the acquisition date, its estimates and assumptions are inherently uncertain and subject to refinement. As a result, during the measurement period, which is generally one year from the acquisition date, any adjustment to the assets acquired and liabilities assumed is recorded against goodwill in the period in which the amount is determined. Any adjustment identified subsequent to the measurement period or the Company's final determination of estimated fair value, whichever comes first, is included in operating results in the period in which the adjustment is determined. Goodwill and Other Long-Lived Assets Goodwill represents the excess of the purchase price in a business combination over the fair value of the net tangible and intangible assets acquired. Goodwill is not amortized but rather is assessed for impairment at the reporting unit level annually during the fourth quarter of each fiscal year or more frequently if the Company believes indicators of impairment exist. Goodwill impairment, if any, is determined by comparing the reporting unit's fair value to its carrying value. An impairment loss is recognized in an amount equal to the excess of the reporting unit's carrying value over its fair value, up to the amount of goodwill allocated to the reporting unit. Other long-lived assets primarily consist of property and equipment, operating lease right-of-use assets and intangible assets. The Company periodically evaluates the recoverability of other long-lived assets whenever events and changes in circumstances, such as reductions in demand or significant economic slowdowns in the industry, indicate that the carrying amount of an asset may not be fully recoverable. When indicators of impairment are present, the carrying values of the asset group are evaluated in relation to the future undiscounted cash flows of the underlying business. The net book value of the underlying asset is adjusted to fair value if the sum of the expected discounted cash flows is less than book value. Fair values are based on estimates of market prices and assumptions concerning the amount and timing of estimated future cash flows and assumed discount rates, reflecting varying degrees of perceived risk. The impairment assessment of goodwill and other long-lived assets involves significant estimates and assumptions, which may be unpredictable and inherently uncertain. These estimates and assumptions include identification of reporting units and asset groups, long-term growth rates, profitability, estimated useful lives, comparable market multiples, and discount rates. Any changes in these assumptions could impact the result of the impairment assessment. There was no impairment of goodwill during fiscal 2022, 2021 and 2020. The Company performed its annual goodwill impairment analysis in fiscal 2022 using an entity valuation which was derived based on the attribution of the agreed-upon purchase price for the Merger. During fiscal 2022, the Company recognized impairment charges on intangible assets associated with the acquisition of Aeris Cleantec AG (see Note 6) and incurred impairment charges related to the Facility restructuring plan discussed within Restructuring Charges in Note 2. There was no impairment of long-lived assets during fiscal 2021 and 2020. Strategic Investments The Company holds non-marketable equity securities as part of its strategic investments portfolio. The Company classifies the majority of these securities as equity securities without readily determinable fair values and measures these investments at cost, less any impairment, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. These investments are valued using significant unobservable inputs or data in an inactive market and the valuation requires the Company's judgment due to the absence of market prices and inherent lack of liquidity. The Company monitors non-marketable equity investments for impairment indicators, such as deterioration in the investee's financial condition and business forecasts and lower valuations in recent or proposed financings. The estimated fair value is based on quantitative and qualitative factors including, but not limited to, subsequent financing activities by the investee and projected discounted cash flows. The Company performs an assessment on a quarterly basis to assess whether triggering events for impairment exist and to identify any observable price changes. During fiscal 2022, the Company recorded impairment charges of $3.9 million related to investments in non-marketable equity securities. Changes in fair value of non-marketable equity investments are recorded in other (expense) income, net on the consolidated statements of operations. At December 31, 2022 and January 1, 2022, the Company's equity securities without readily determinable fair values totaled $15.1 million and $16.3 million, respectively, and are included in other assets on the consolidated balance sheets. Warranty The Company generally provides a one-year warranty on all of its products except in countries where a two-year warranty is required against defects in materials and workmanship. The Company's standard warranty provides for repair or replacement of the associated products during the warranty period. The Company records estimated warranty costs in the period the related revenue is recognized based on historical experience, expectations of future costs to repair or replace including freight and knowledge of specific product failures outside the Company's historical experience. Actual results could differ from these estimates, which could cause increases or decreases to the warranty reserves in future periods. Financial Instruments and Hedging Activities The Company utilizes derivative instruments to partially offset its financial risks to foreign exchange risk. The Company does not engage in speculative hedging activity. In order to account for a derivative instrument as a cash flow hedge, specific criteria must be met, including: (i) ensuring at the inception of the hedge that formal documentation exists for both the hedging relationship and the entity’s risk management objective and strategy for undertaking the hedge and (ii) at the inception of the hedge and on an ongoing basis, the hedging relationship is expected to be highly effective in achieving offsetting changes in fair value attributed to the hedged risk during the period that the hedge is designated. Cash flow hedge amounts that are included in the assessment of hedge effectiveness are deferred in accumulated other comprehensive income (loss) until the hedged item is recognized in earnings. Deferred gains and losses associated with cash flow hedges are recognized as a component of net sales in the same period as the related revenue is recognized. Absent meeting these criteria, changes in fair value are recognized in other (expense) income, net, in the consolidated statements of operations. The Company may also enter into non-designated foreign currency contracts to offset a portion of the foreign currency exchange gains and losses generated by the remeasurement of certain assets and liabilities denominated in non-functional currencies. Changes in fair value are recognized in other (expense) income, net, in the consolidated statements of operations. Fair Value Measurements The Company accounts for certain assets and liabilities at fair value. The fair value is established based on a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. These tiers include: • Level 1 - observable inputs such as quoted prices for identical instruments in active markets; • Level 2 - inputs other than quoted prices in active markets that are either directly or indirectly observable; and • Level 3 - unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Stock-Based Compensation The Company accounts for stock-based compensation through recognition of the fair value of the stock-based compensation as a charge against earnings. The Company issues equity incentive awards in the form of restricted stock units ("RSUs") and performance-based restricted stock units ("PSUs"). The fair value for RSUs is based on the closing share price of the Company's common stock on the date of grant. PSUs are aligned to specified performance targets such as financial metrics or the relative returns of the Company's common stock ("TSRs"). The fair value of PSUs aligned to specified performance metrics is determined based on the number of units expected to vest upon achievement of the performance conditions. The fair value for PSUs aligned to the TSR is based on a Monte Carlo simulation model. The Company recognizes stock-based compensation as an expense on a straight-line basis, over the requisite service period. The Company accounts for forfeitures as they occur, rather than applying an estimated forfeiture rate. Research and Development Costs incurred in the research and development of the Company’s products are expensed as incurred. Advertising Expense Advertising costs are expensed as incurred and included in selling and marketing expenses. During the years ended December 31, 2022, January 1, 2022 and January 2, 2021 advertising expense totaled $146.6 million, $147.2 million and $145.2 million, respectively. Income Taxes The Company accounts for its income taxes using the asset and liability method, under which the Company recognizes the amount of taxes payable or refundable for the current year. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis using enacted tax rates in effect in the years in which those temporary differences are expected to be recovered or settled in each jurisdiction. A valuation allowance is provided if, based upon the weight of available evidence, it is more likely than not that the related benefits will not be realized. In assessing the recoverability of its deferred tax assets, the Company evaluates all available evidence, both positive and negative, to assess whether it is more likely than not that sufficient future taxable income will be generated to permit use of existing deferred tax assets in each taxpaying jurisdiction. For any deferred tax asset that exceeds the amount for which it is more likely than not that the Company will realize a benefit, the Company establishes a valuation allowance. During the third quarter of fiscal 2022, the Company concluded that, based on its evaluation of available positive and negative evidence, it is no longer more likely than not that its net U.S. federal and state deferred tax assets are recoverable. In assessing the realizability of its U.S. deferred tax assets, the key factors used to determine positive and negative evidence included its recent losses resulting in cumulative loss for the three-year period ended December 31, 2022, current macroeconomic trends, and expected future reversals of existing taxable temporary differences. Such objective negative evidence limits the Company's ability to consider other subjective evidence, such as its projections for future growth. Given the weight of objectively verifiable historical losses from the Company's U.S. operations, the Company recorded a valuation allowance of $57.5 million in the third quarter of fiscal 2022 as a reserve against our net U.S. federal and state deferred tax assets. The Company expects to continue to record a valuation allowance against these assets until sufficient positive evidence exists to support its reversal. As of December 31, 2022, January 1, 2022 and January 2, 2021, the Company had a valuation allowance of $99.4 million, $13.1 million and $7.6 million, respectively, for certain deferred tax assets for which the Company believes do not meet the "more likely than not" criteria for recognition. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in the income tax provision. Concentration of Credit Risk and Significant Customers Financial instruments which potentially expose the Company to concentrations of credit risk consist of accounts receivable and cash and cash equivalents. Management believes its credit policies are prudent and reflect normal industry terms and business risk. At December 31, 2022 and January 1, 2022, one customer accounted for 16.6% and 14.5% , respectively, of the Company's accounts receivable balance. For the fiscal years ended December 31, 2022, January 1, 2022, and January 2, 2021, there was one customer that accounted for 10% or more of total revenue, representing 22.6%, 21.8% and 22.7%, of the Company's total revenue, respectively. The Company maintains its cash in bank deposit accounts and money market fund

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer	3. Revenue Recognition The Company primarily derives its revenue from the sale of consumer robots and accessories. The Company sells products directly to consumers through online stores and indirectly through resellers and distributors. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Revenue is allocated to distinct performance obligations and is recognized net of allowances for returns and other credits and incentives. Revenue is recognized only to the extent that it is probable that a significant reversal of revenue will not occur and when collection is considered probable. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from revenue. Shipping and handling expenses are considered fulfillment activities and are expensed as incurred. Frequently, the Company’s contracts with customers contain multiple promised goods or services. Such contracts may include any of the following, the consumer robot, downloadable app, cloud services, accessories on demand, potential future unspecified software upgrades, premium customer care and extended warranties. For these contracts, the Company accounts for the promises separately as individual performance obligations if they are distinct. Performance obligations are considered distinct if they are both capable of being distinct and distinct within the context of the contract. In determining whether performance obligations meet the criteria for being distinct, the Company considers a number of factors, such as the degree of interrelation and interdependence between obligations, and whether or not the good or service significantly modifies or transforms another good or service in the contract. The Company’s consumer robots are highly dependent on, and interrelated with, the embedded software and cannot function without the software. As such, the consumer robots are accounted for as a single performance obligation. The Company has determined that the app, cloud services and potential future unspecified software upgrades represent one performance obligation to the customer to enhance the functionality and interaction with the robot (referred to collectively as "Cloud Services"). Other services and support are considered distinct and therefore are treated as separate performance obligations. The Company allocates revenue to all distinct performance obligations based on their relative stand-alone selling prices ("SSPs"). When available, the Company uses observable prices to determine SSPs. When observable prices are not available, SSPs are established that reflect the Company’s best estimates of what the selling prices of the performance obligations would be if they were sold regularly on a stand-alone basis. The Company’s process for estimating SSPs without observable prices considers multiple factors that may vary depending upon the facts and circumstances related to each performance obligation including market data or the estimated cost of providing the products or services. The transaction price allocated to the robot is recognized as revenue at a point in time when control is transferred, generally as title and risk of loss pass, and when collection is considered probable. The transaction price allocated to the Cloud Services is deferred and recognized on a straight-line basis over the estimated term of the Cloud Services. Other services and support are recognized over their service periods. For contracts with a duration of greater than one year, the transaction price allocated to performance obligations that are unsatisfied as of December 31, 2022 and January 1, 2022 was $23.2 million and $20.9 million, respectively. The Company’s products generally carry a one-year or two-year limited warranty that promises customers that delivered products are as specified. The Company does not consider these assurance-type warranties as a separate performance obligation and therefore, the Company accounts for such warranties under ASC 460, "Guarantees." For contracts with the right to upgrade to a new product after a specified period of time, the Company accounts for this trade-in right as a guarantee obligation under ASC 460. The total transaction price is reduced by the full amount of the trade-in right's fair value and the remaining transaction price is allocated between the performance obligations within the contract. The Company provides limited rights of returns for direct-to-consumer sales generated through its online stores and certain resellers and distributors. The Company records an allowance for product returns based on specific terms and conditions included in the customer agreements or based on historical experience and the Company's expectation of future returns. In addition, the Company may provide other credits or incentives which are accounted for as variable consideration when estimating the amount of revenue to recognize. Where appropriate, these estimates take into consideration relevant factors such as the Company’s historical experience, current contractual requirements, specific known market events and forecasted inventory level in the channels. Overall, these reserves reflect the Company’s best estimates, and the actual amounts of consideration ultimately received may differ from the Company’s estimates. Returns and credits are estimated at the time of sale and updated at the end of each reporting period as additional information becomes available. As of December 31, 2022, the Company had reserves for product returns of $49.2 million and other credits and incentives of $106.5 million. As of January 1, 2022, the Company had reserves for product returns of $56.8 million and other credits and incentives of $101.6 million. The Company regularly evaluates the adequacy of its estimates for product returns and other credits and incentives. Future market conditions and product transitions may require the Company to take action to change such programs and related estimates. When the variables used to estimate these reserves change, or if actual results differ significantly from the estimates, the Company increases or reduces revenue to reflect the impact. During fiscal 2022 and 2021, changes to these estimates related to performance obligations satisfied in prior periods were not material.

Leases [Abstract]
Lessee, Operating Leases [Text Block]	4. Leases The Company's leasing arrangements primarily consist of operating leases for its facilities which include corporate, sales and marketing and research and development offices and equipment under various non-cancelable lease arrangements. The operating leases expire at various dates through 2030. For leases with terms greater than 12 months, the Company records the related right-of-use asset and lease obligation at the present value of lease payments over the term. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Lease expense is recognized on a straight-line basis over the lease term. The Company's leases typically include rental escalation clauses, renewal options and/or termination options that are factored into the determination of lease payments when appropriate. The Company does not separate lease and non-lease components of contracts and excludes all variable lease payments from the measurement of right-of-use assets and lease liabilities. The Company's variable lease payments generally include usage based nonlease components. The Company's lease agreements do not contain any residual value guarantees or restrictive covenants. The Company's existing leases do not provide a readily determinable implicit rate. Therefore, the Company estimates its incremental borrowing rate to discount the lease payments. At December 31, 2022, the Company's weighted average discount rate was 4.02%, while the weighted average remaining lease term was 6.70 years. The components of lease expense were as follows (in thousands): December 31, 2022 January 1, 2022 January 2, 2021 Operating lease cost $ 6,622 $ 8,510 $ 9,363 Variable lease cost 3,644 3,633 3,583 Total lease cost $ 10,266 $ 12,143 $ 12,946 Supplemental cash flow information related to leases was as follows (in thousands): December 31, 2022 January 1, 2022 January 2, 2021 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 8,187 $ 8,762 $ 9,862 Right-of-use assets obtained in exchange for lease obligations: Operating leases $ — $ — $ 2,310 Maturities of operating lease liabilities were as follows as of December 31, 2022 (in thousands): 2023 $ 7,265 2024 6,598 2025 5,688 2026 5,800 2027 5,877 Thereafter 13,048 Total minimum lease payments $ 44,276 Less: imputed interest 5,614 Present value of future minimum lease payments $ 38,662 Less: current portion of operating lease liabilities (Note 7) 5,415 Long-term lease liabilities $ 33,247

As a result, the Company recognized goodwill of $52.7 million and acquired intangible assets of $21.0 million mainly related to developed technology with a weighted estimated useful life of 5 years. The acquisition was a stock purchase and the goodwill resulting from this acquisition is not deductible for tax purposes. The results of operations of the acquired entity has been included within its consolidated results of operations from the acquisition date and was not material to its consolidated financial statements. Intangible assets consisted of the following (in thousands): December 31, 2022 January 1, 2022 Cost Accumulated Net Cost Accumulated Net Completed technology $ 33,909 $ 28,383 $ 5,526 $ 43,727 $ 27,752 $ 15,975 Tradename 100 100 — 100 100 — Customer relationships 10,104 4,370 5,734 16,628 4,193 12,435 Reacquired distribution rights 29,915 29,915 — 32,096 32,096 — Non-competition agreements 245 245 — 260 260 — Total $ 74,273 $ 63,013 $ 11,260 $ 92,811 $ 64,401 $ 28,410 Amortization expense related to acquired intangible assets was $15.4 million, $2.3 million and $2.9 million for the fiscal years ended December 31, 2022, January 1, 2022 and January 2, 2021, respectively. During the third quarter of 2022, the Company evaluated its long-lived assets, including intangible assets, for indicators of impairment given recent and anticipated unfavorable changes in the macroeconomic environment on the Company's short-term forecasts as well as the Company's negative operating cash flows and operating losses. As a result, the Company determined indicators of impairment existed for the asset group associated with the Company's acquisition of Aeris Cleantec AG and performed an undiscounted cash flow analysis. Based on this undiscounted cash flow analysis, the Company determined that the cash flows expected to be generated by this asset group over the estimated remaining useful life were not sufficient to recover the carrying value of the asset group. As a result, the Company was required to perform Step 3 of the impairment test and determine the fair value of the asset group utilizing the income approach which is based on a discounted cash flow analysis. The Company concluded that the fair value of the asset group was below its carrying value and recorded an $11.1 million impairment loss on these intangible assets. The impairment loss is recorded in amortization of acquired intangible assets under operating expenses on the consolidated statement of operations. The estimated future amortization expense related to current intangible assets in each of the five succeeding fiscal years is expected to be as follows (in thousands): Cost of Revenue Operating Expenses Total 2023 $ 1,133 $ 708 $ 1,841 2024 1,133 708 1,841 2025 1,133 708 1,841 2026 1,133 708 1,841 2027 994 708 1,702 Thereafter — 2,194 2,194 Total $ 5,526 $ 5,734 $ 11,260

Revolving Line of Credit	8. Working Capital Facility Credit Facility As of December 31, 2022, we had a $150.0 million secured revolving line of credit which expires in June 2023, and no outstanding borrowings under our revolving credit facility. The credit facility contains customary terms and conditions for credit facilities of this type, including restrictions on our ability to incur or guarantee additional indebtedness, create liens, enter into transactions with affiliates, make loans or investments, sell assets, pay dividends or make distributions on, or repurchase, our stock, and consolidate or merge with other entities. The credit facility contains customary events of default, including for payment defaults, breaches of representations, breaches of affirmative or negative covenants, cross defaults to other material indebtedness, bankruptcy and failure to discharge certain judgments. If a default occurs and is not cured within any applicable cure period or is not waived, our obligations under the credit facility may be accelerated. On May 4, 2022, we entered into a Second Amendment (the "Second Amendment") to the Amended and Restated Credit Agreement (as amended, the "Credit Agreement") with Bank of America N.A. (the "Lender") with an effective date of March 31, 2022. The Second Amendment waived the quarterly tested leverage and interest coverage covenants in the Credit Agreement for the first, second and third quarters of 2022. The interest coverage ratio calculation for the fourth quarter of 2022 was changed to a trailing nine months. Additionally, a new liquidity covenant was added for the remainder of 2022. The Second Amendment also increased the borrowing rate under the Credit Agreement for 2022 to LIBOR plus 1.5%. On October 28, 2022, we entered into a Third Amendment to the Credit Agreement (the "Third Amendment"). The Third Amendment temporarily increased the commitments under the facility to $200.0 million for the time period from October 28, 2022 to December 29, 2022. On December 30, 2022, the commitment was reduced by $50.0 million and returned to the previous $150.0 million. In addition, the Third Amendment replaced the quarterly tested leverage and interest coverage covenants with a new minimum cash requirement of $25.0 million to be tested on October 31, 2022 and November 30, 2022. The Third Amendment also requires that the borrowing under the Credit Agreement must be below $75.0 million on December 30, 2022 and for ten On January 17, 2023, the Company entered into a Fourth Amendment (the "Fourth Amendment") to the Credit Agreement which reduced the amount of the facility from $150.0 million to $100.0 million and increased the interest rate of (1) Term SOFR Loans to 4.50%, (2) Base Rate Loans to 3.50%, and (3) unused Commitments to 3.50%. In addition, the Fourth Amendment established a borrowing base for the revolving facility equal to the total of 80% of eligible receivables, 50% of eligible inventory, and upon the satisfaction of certain conditions, up to 30% of eligible in-transit inventory, all subject to any applicable reserves. Additionally, the Fourth Amendment required the Company to maintain $25.0 million of cash in the U.S. at all times, which is tested monthly and replaced the requirement that the borrowing under the Credit Agreement be under $75.0 million (1) on December 30, 2022 and (2) for ten thirty As of December 31, 2022, we were in compliance with covenants under the Credit Agreement. Lines of Credit The Company has a secured letter of credit facility with Bank of America, N.A., available to fund letters of credit up to an aggregate outstanding amount of $5.0 million. As of December 31, 2022, the Company had letters of credit outstanding of $0.4 million under the letter of credit facility and other lines of credit with Bank of America, N.A.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	9. Derivative Instruments and Hedging Activities The Company operates internationally and, in the normal course of business, is exposed to fluctuations in foreign currency exchange rates. The foreign currency exposures typically arise from transactions denominated in currencies other than the functional currency of the Company's operations, primarily the British Pound, Canadian Dollar, Euro and Japanese Yen. The Company uses derivative instruments that are designated in cash flow hedge relationships to reduce or eliminate the effects of foreign exchange rate change on sales. These contracts typically have maturities of three years or less. At December 31, 2022 and January 1, 2022, the Company had outstanding cash flow hedges with a total notional value of $362.9 million and $423.3 million, respectively. The Company also enters into economic hedges that are not designated as hedges from an accounting standpoint to reduce or eliminate the effects of foreign exchange rate changes typically related to short term trade receivables and payables. These contracts typically have maturities of twelve months or less. As of December 31, 2022 and January 1, 2022, the Company had outstanding foreign currency economic hedges with a total notional value of $242.0 million and $325.4 million, respectively. During the third quarter of 2022, the appreciation of the U.S. dollar resulted in the Company’s foreign currency forward contracts being substantially in-the-money. Given the increased cash value of the hedges and the Company’s overall desire to strengthen its cash position, the Company terminated the contracts during the third quarter of 2022, resulting in cash proceeds of $51.7 million which were recognized within cash used in operating activities in the consolidated statement of cash flows. Amounts previously recorded in AOCI were frozen at the time of termination, and will be recognized in earnings when the original forecasted transaction occurs. In conjunction with the termination of the existing contracts, the Company entered into new foreign currency forward contracts with the same notional values and value dates.

In September 2021, Wells Fargo delivered an additional 254,933 shares of the Company's common stock to complete settlement of the ASR agreement. Under this agreement, the Company repurchased a total of 1,198,218 shares of its common stock at an average price of $83.46, totaling $100.0 million during the third quarter of 2021.

Stock-Based Compensation	12. Stock-Based Compensation The Company has awards and options outstanding under three stock incentive plans: the 2005 Stock Option and Incentive Plan (the "2005 Plan"), the 2015 Stock Option and Incentive Plan (the "2015 Plan") and the 2018 Stock Option and Incentive Plan (the "2018 Plan" and together with the 2005 Plan and the 2015 Plan, the "Plans"). The 2018 Plan is the only one of the three plans under which new awards may currently be granted. Under the 2018 Plan, which became effective on May 23, 2018, 1,750,000 shares were initially reserved for issuance in the form of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock awards, restricted stock units, unrestricted stock awards, cash-based awards, and dividend equivalent rights. On May 21, 2020, the stockholders approved an amendment to the 2018 Plan to increase the number of aggregate shares authorized for issuance to 2,495,000 shares, an increase of 745,000 shares. On May 27, 2022, the stockholders approved an amendment to the 2018 Plan to increase the number of aggregate shares authorized for issuance to 3,395,000 shares, an increase of 900,000 shares. Stock awards returned to the Plans, with the exception of those issued under the 2005 Plan, as a result of their expiration, cancellation or termination are automatically made available for issuance under the 2018 Plan. As of December 31, 2022, there were 1,394,174 shares available for future grant under the 2018 Plan. The Company recognized $31.9 million, $21.7 million and $30.0 million of stock-based compensation expense during the fiscal years ended December 31, 2022, January 1, 2022, and January 2, 2021, respectively.

As of December 31, 2022, the unamortized compensation costs associated with restricted stock units was $71.1 million with a weighted-average remaining recognition period of 2.19 years. The following table summarizes the time-based restricted stock unit activity for fiscal 2022, 2021 and 2020: Number of Weighted Average Outstanding at December 28, 2019 819,232 $ 73.83 Granted 493,908 61.53 Vested (318,079) 67.95 Forfeited (101,028) 75.20 Outstanding at January 2, 2021 894,033 68.97 Granted 523,496 88.73 Vested (314,427) 71.36 Forfeited (99,886) 75.82 Outstanding at January 1, 2022 1,003,216 77.85 Granted 638,554 54.26 Vested (321,443) 78.10 Forfeited (187,227) 73.45 Outstanding at December 31, 2022 1,133,100 $ 65.21 The aggregate intrinsic value of outstanding time-based restricted stock units at December 31, 2022 was $54.5 million based on the Company's closing stock price on December 31, 2022 of $48.13, with a weighted average remaining contractual term of 1.22 years. Performance-Based Restricted Stock Units The Company grants performance-based restricted stock units ("PSUs") to certain of its employees that vest on the satisfaction of service and performance or market conditions. The performance conditions are based on certain financial performance targets at the end of a three year performance period, and therefore awards generally cliff vest at the end of a three year performance period. The market conditions are based on the relative TSRs compared to a certain index for each performance period, and therefore awards vest at the end of each performance period. The number of shares actually vested may range from 0% to 200% of the target number of PSUs granted based on the actual achievement of the conditions. The unamortized fair value as of December 31, 2022 associated with performance based restricted stock units was $4.7 million with a weighted-average remaining recognition period of 0.99 years. The following table summarizes the performance-based restricted stock unit activity for fiscal 2022, 2021 and 2020: Number of Weighted Average Outstanding at December 28, 2019 216,231 $ 78.42 Granted 130,284 46.77 Vested (71,734) 61.44 Forfeited (45,129) 75.17 Outstanding at January 2, 2021 229,652 66.41 Granted 134,127 94.74 Vested (55,503) 68.41 Forfeited (23,154) 71.68 Outstanding at January 1, 2022 285,122 78.92 Granted 153,676 57.94 Vested — — Forfeited (71,616) 97.31 Outstanding at December 31, 2022 367,182 $ 66.55 The aggregate intrinsic value of outstanding PSUs was $17.7 million based on the Company's closing stock price on December 31, 2022 of $48.13 with a weighted average remaining contractual term of 0.99 years. Employee Stock Purchase Plan In May 2017, the Company’s stockholders approved the 2017 Employee Stock Purchase Plan ("ESPP"). Eligible employees could purchase the Company’s common stock through payroll deductions at a price equal to 85% of the lower of the fair market values of the stock as of the beginning or the end of six-month offering periods beginning November 15 and May 15 of each year. An employee’s payroll deductions under the ESPP were limited to 15% of the employee’s compensation, up to $4,000 each period, for the purchase of common stock not to exceed 1,000 shares per offering period. The Company recognized $0.8 million, $1.2 million, and $1.0 million of stock-based compensation expense during the fiscal years ended December 31, 2022, January 1, 2022, and January 2, 2021, respectively. The final offering period under the ESPP closed on November 15, 2022, and under the terms of the Merger Agreement, no additional offering period may be commenced. The Company will terminate the ESPP immediately prior to, but contingent upon the occurrence of, the closing of the Merger.

Commitments and Contingencies	13. Commitments and Contingencies Legal Proceedings From time to time and in the ordinary course of business, the Company is subject to various claims, charges and litigation. The outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to us, which could materially affect our financial condition or results of operations. Outstanding Purchase Orders As of December 31, 2022, we had outstanding purchase orders aggregating approximately $151.5 million. Included in the outstanding purchase orders, $18.5 million are not cancellable without penalty which is a decrease of $23.4 million from prior year as we continue to manage liquidity. The purchase orders, the majority of which are with our contract manufacturers for the purchase of inventory in the normal course of business, are for manufacturing and non-manufacturing related goods and services. Guarantees and Indemnification Obligations The Company enters into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, the Company indemnifies and agrees to reimburse the indemnified party for losses incurred by the indemnified party, generally the Company’s customers, in connection with any patent, copyright, trade secret or other proprietary right infringement claim by any third party. The term of these indemnification agreements is generally perpetual any time after execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal. Accordingly, the Company has no liabilities recorded for these agreements as of December 31, 2022 and January 1, 2022, respectively. Warranty The Company provides warranties on most products and has established a reserve for warranty obligations based on estimated warranty costs. The reserve is included as part of accrued expenses (Note 7) in the accompanying consolidated balance sheets. Activity related to the warranty accrual was as follows (in thousands): Fiscal Year Ended December 31, January 1, January 2, Balance at beginning of period $ 32,019 $ 24,392 $ 13,856 Provision 22,155 42,430 28,884 Warranty claims (26,795) (34,803) (18,348) Balance at end of period $ 27,379 $ 32,019 $ 24,392

This rule became effective for the Company during the year and resulted in the capitalization of R&D costs $224.5 million. The Company will amortize these costs for tax purposes over 5 years if the R&D was performed in the U.S. and over 15 years if the R&D was performed outside the U.S. The Company intends to continue to invest all of its unremitted foreign earnings, as well as the capital in its foreign subsidiaries, indefinitely outside of the U.S. At December 31, 2022, the Company has unremitted foreign earnings for which any unrecognized deferred tax liability on these unremitted earnings would be immaterial. The Company has federal and foreign net operating loss carryforwards of $3.8 million and $29.0 million, respectively, as of December 31, 2022. As of December 31, 2022, the Company has a full valuation allowance of $0.9 million against its U.S. net operating loss carryforwards and a valuation allowance of $4.7 million in certain foreign jurisdictions for net operating loss carryforwards and other deferred tax assets that have statutory limitations on deductibility. The Company has federal research and development credit carryforwards of $4.6 million as of December 31, 2022 that will expire in 2043. It has state research and development credit carryforwards of $23.1 million and $19.4 million as of December 31, 2022 and January 1, 2022, respectively, which expire from 2029 to 2038. Under the Internal Revenue Code and state law, 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. During the third quarter of fiscal 2022, the Company concluded that, based on its evaluation of available positive and negative evidence, it is no longer more likely than not that its net U.S. federal and state deferred tax assets are recoverable. In assessing the realizability of its U.S. deferred tax assets, the key factors used to determine positive and negative evidence included its recent losses resulting in cumulative loss for the three-year period ended December 31, 2022, current macroeconomic trends, and expected future reversals of existing taxable temporary differences. Such objective negative evidence limits the Company's ability to consider other subjective evidence, such as its projections for future growth. Given the weight of objectively verifiable historical losses from the Company's U.S. operations, the Company recorded a valuation allowance of $57.5 million in the third quarter of fiscal 2022 as a reserve against our net U.S. federal and state deferred tax assets. The change in valuation allowance for all of fiscal 2022 was $86.3 million. As of December 31, 2022, January 1, 2022 and January 2, 2021, the Company had a valuation allowance of $99.4 million, $13.1 million and $7.6 million, respectively, for all of its U.S. deferred tax assets and certain foreign deferred tax assets for which the Company believes do not meet the "more likely than not" criteria for recognition. A valuation allowance is a non-cash charge, and does not limit the Company’s ability to utilize its deferred tax assets, including its ability to utilize tax loss and credit carryforward amounts, against future taxable income. The amount of the deferred tax assets considered realizable, and the associated valuation allowance, could be adjusted in a future period if estimates of future taxable income change or if objective negative evidence in the form of cumulative losses is no longer present and additional weight is given to subjective evidence such as projections for future growth. The following table summarized the activity related to the Company's gross unrecognized tax benefits (in thousands): Fiscal Year Ended December 31, January 1, January 2, Balance at beginning of period $ 9,842 $ 8,559 $ 7,121 Increase for tax positions related to the current year 1,117 914 765 Increase for tax positions related to prior years 672 369 1,231 Decrease related to settlement with taxing authorities (1,412) — — Decrease for lapses of statute of limitations (613) — (558) Balance at end of period $ 9,606 $ 9,842 $ 8,559 The Company accrues interest and, if applicable, penalties for any uncertain tax positions as a component of income tax expense. As of December 31, 2022, January 1, 2022 and January 2, 2021 there were no material accrued interest or penalties. Significant judgment is required in evaluating its uncertain tax positions and determining its provision for income taxes. The Company does not expect a significant change in the amount of unrecognized tax benefits within the next 12 months. If all of the Company's unrecognized tax benefits as of December 31, 2022 were to become recognizable in the future, it would record a $10.8 million benefit, inclusive of interest, to the income tax provision.

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation and Foreign Currency Translation The accompanying consolidated financial statements include those of iRobot and its subsidiaries, after elimination of all intercompany balances and transactions. iRobot has prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP"). For the Company's subsidiaries that transact in a functional currency other than the U.S. dollar, assets and liabilities are translated into U.S. dollars at period-end foreign exchange rates. Revenues and expenses are translated into U.S. dollars at the average foreign exchange rates for the period. Translation adjustments are excluded from the determination of net income (loss) and are recorded in accumulated other comprehensive income (loss), a separate component of stockholders' equity.
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. As used in the Annual Report on Form 10-K, "fiscal 2022" refers to the 52-week fiscal year ending December 31, 2022, "fiscal 2021" refers to the 52-week fiscal year ended January 1, 2022, and "fiscal 2020" refers to the 53-week fiscal year ended January 2, 2021.
Use of Estimates	Use of Estimates The preparation of these financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenue and expenses. These estimates and judgments, include but are not limited to, revenue recognition, including performance obligations, standalone selling price, variable consideration and other obligations such as sales incentives and product returns; allowance for credit losses; impairment of goodwill and long-lived assets; valuation of non-marketable equity investments; product warranties; inventory excess and obsolescence; loss contingencies; accounting for stock-based compensation including valuation and assessments of performance-based awards; accounting for income taxes and related valuation allowances. The Company bases its estimates and assumptions on historical experience, market participant fair value considerations, projected future cash flows, current economic conditions, and various other factors that the Company believes are reasonable under the circumstances. Actual results and outcomes may differ from the Company’s estimates and assumptions.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with maturity of three months or less at the time of purchase to be cash and cash equivalents. The Company invests its excess cash primarily in money market funds or demand deposit accounts of major financial institutions. Accordingly, its cash and cash equivalents are subject to minimal credit and market risk. At December 31, 2022 and January 1, 2022, cash and cash equivalents totaled $117.9 million and $201.5 million, respectively. These cash and cash equivalents are carried at cost, which approximates fair value.
Short Term Investments	Short Term Investments The Company's short term investments include marketable equity securities with readily determinable fair value. The fair value of investments is determined based on quoted market prices at the reporting date for those instruments. The change in fair value of the Company's investments in marketable equity securities is recognized as unrealized gains and losses in other (expense) income, net at the end of each reporting period. Investments consisted of the following (in thousands): December 31, January 1, Cost Fair Cost Fair Marketable equity securities $ — $ — $ 23,286 $ 33,044 Total short term investments $ — $ — $ 23,286 $ 33,044 On July 22, 2021, Matterport, Inc. ("Matterport"), of which the Company held non-marketable equity securities, completed a merger with a special purpose acquisition company and began trading on Nasdaq under the symbol "MTTR." Prior to the merger, the Company accounted for the shares in Matterport as equity securities without readily determinable fair value. Upon consummation of the merger, the Company received 1.6 million shares of MTTR. The post merger Matterport shares received were subject to time based contractual sales restrictions which expired in January 2022. These shares were accounted for as marketable equity securities and measured at fair value with unrealized gains and losses recognized in other (expense) income, net at the end of each reporting period. During fiscal 2021, the Company recorded gains of $30.2 million associated with the Matterport investment. During the first quarter of 2022, the Company sold these Matterport shares and received net proceeds of $16.2 million. In addition, the Company received an additional 0.2 million shares of Matterport during the first quarter of 2022 upon achievement of conditions set forth in the merger agreement, and sold these shares during the second quarter of 2022 for net proceeds of $1.2 million. During fiscal 2022, the Company recognized losses of $17.1 million in other (expense) income, net related to the sales of Matterport shares. As of December 31, 2022, the Company did not have any short term investments. On July 1, 2020, Teladoc Health, Inc. ("Teladoc") closed on its previously announced acquisition of InTouch Health, of which the Company held non-marketable equity securities. In exchange for its shares of InTouch Health, the Company received 0.2 million shares of Teladoc and recorded a gain of $38.6 million to other income, net during fiscal 2020. The Teladoc shares received were subject to time based contractual sales restrictions which expired in January 2021. These shares were accounted for as marketable equity securities and measured at fair value with unrealized gains and losses recognized in other (expense) income, net at the end of each reporting period. As a result, the Company entered into an economic hedge in July 2020 to reduce the Company's exposure to stock price fluctuations during the restricted period. During the first quarter of 2021, the Company received net proceeds of $51.5 million related to the sale of Teladoc shares with gross proceeds of $60.1 million, net of settlement payment of $8.6 million for the related economic hedge.
Credit Losses	Allowance for Credit LossesThe Company maintains an allowance for credit losses for accounts receivable using an expected loss model that requires the use of forward-looking information to calculate credit loss estimate. The expected loss methodology is developed through consideration of factors including, but not limited to, historical collection experience, current customer credit ratings, customer concentrations, current and future economic and market conditions and age of the receivable. The Company reviews and adjusts the allowance for credit losses on a quarterly basis. Accounts receivable balances are written off against the allowance when the Company determines that the balances are not recoverable.
Accounts receivable allowances	Accounts receivable allowances Allowance for product returns : The Company records an allowance for product returns based on specific terms and conditions included in the customer agreements or based on historical experience and the Company's expectation of future returns. Allowance for other credits and incentives: The Company records an allowance related to customer incentives such as discounts, promotions, price protection and other support programs. The allowance is based on specific terms and conditions included in customer agreements, specific programs and sell-through expectations, historical experience and other factors.
Inventory	Inventory Inventory primarily consists of finished goods and, to a lesser extent, components, which are purchased from contract manufacturers. Inventory is stated at the lower of cost or net realizable value with cost being determined using the standard cost method, which approximates actual costs determined on the first-in, first-out basis. Inventory costs primarily consist of materials, inbound freight, import duties, tariffs, and other handling fees. The Company writes down its inventory for estimated obsolescence or excess inventory based upon assumptions around market conditions and estimates of future demand. Net realizable value is the estimated selling price less estimated costs of completion, disposal and transportation. Adjustments to reduce inventory to net realizable value are recognized in cost of revenue and have not been significant for the periods presented.
Warranty	Warranty The Company generally provides a one-year warranty on all of its products except in countries where a two-year warranty is required against defects in materials and workmanship. The Company's standard warranty provides for repair or replacement of the associated products during the warranty period. The Company records estimated warranty costs in the period the related revenue is recognized based on historical experience, expectations of future costs to repair or replace including freight and knowledge of specific product failures outside the Company's historical experience. Actual results could differ from these estimates, which could cause increases or decreases to the warranty reserves in future periods.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives as follows: Estimated Useful Life Computer and equipment 2-5 years Furniture and fixtures 5 Machinery and tooling 2-5 Business applications software 3-7 Leasehold improvements Lesser of economic benefit period or term of lease
Business Combinations	Business Combinations The Company allocates the purchase price of each acquisition to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values as of the date of acquisition. Goodwill is measured as the excess of the purchase price over the value of net identified assets acquired. While the Company uses its best estimates and assumptions to accurately value assets acquired, liabilities assumed, and contingent consideration, where applicable, at the acquisition date, its estimates and assumptions are inherently uncertain and subject to refinement. As a result, during the measurement period, which is generally one year from the acquisition date, any adjustment to the assets acquired and liabilities assumed is recorded against goodwill in the period in which the amount is determined. Any adjustment identified subsequent to the measurement period or the Company's final determination of estimated fair value, whichever comes first, is included in operating results in the period in which the adjustment is determined.
Goodwill and Other Long-Lived Assets	Goodwill and Other Long-Lived Assets Goodwill represents the excess of the purchase price in a business combination over the fair value of the net tangible and intangible assets acquired. Goodwill is not amortized but rather is assessed for impairment at the reporting unit level annually during the fourth quarter of each fiscal year or more frequently if the Company believes indicators of impairment exist. Goodwill impairment, if any, is determined by comparing the reporting unit's fair value to its carrying value. An impairment loss is recognized in an amount equal to the excess of the reporting unit's carrying value over its fair value, up to the amount of goodwill allocated to the reporting unit. Other long-lived assets primarily consist of property and equipment, operating lease right-of-use assets and intangible assets. The Company periodically evaluates the recoverability of other long-lived assets whenever events and changes in circumstances, such as reductions in demand or significant economic slowdowns in the industry, indicate that the carrying amount of an asset may not be fully recoverable. When indicators of impairment are present, the carrying values of the asset group are evaluated in relation to the future undiscounted cash flows of the underlying business. The net book value of the underlying asset is adjusted to fair value if the sum of the expected discounted cash flows is less than book value. Fair values are based on estimates of market prices and assumptions concerning the amount and timing of estimated future cash flows and assumed discount rates, reflecting varying degrees of perceived risk. The impairment assessment of goodwill and other long-lived assets involves significant estimates and assumptions, which may be unpredictable and inherently uncertain. These estimates and assumptions include identification of reporting units and asset groups, long-term growth rates, profitability, estimated useful lives, comparable market multiples, and discount rates. Any changes in these assumptions could impact the result of the impairment assessment. There was no impairment of goodwill during fiscal 2022, 2021 and 2020. The Company performed its annual goodwill impairment analysis in fiscal 2022 using an entity valuation which was derived based on the attribution of the agreed-upon purchase price for the Merger. During fiscal 2022, the Company recognized impairment charges on intangible assets associated with the acquisition of Aeris Cleantec AG (see Note 6) and incurred impairment charges related to the Facility restructuring plan discussed within Restructuring Charges in Note 2. There was no impairment of long-lived assets during fiscal 2021 and 2020.
Other Assets	Strategic Investments The Company holds non-marketable equity securities as part of its strategic investments portfolio. The Company classifies the majority of these securities as equity securities without readily determinable fair values and measures these investments at cost, less any impairment, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. These investments are valued using significant unobservable inputs or data in an inactive market and the valuation requires the Company's judgment due to the absence of market prices and inherent lack of liquidity. The Company monitors non-marketable equity investments for impairment indicators, such as deterioration in the investee's financial condition and business forecasts and lower valuations in recent or proposed financings. The estimated fair value is based on quantitative and qualitative factors including, but not limited to, subsequent financing activities by the investee and projected discounted cash flows. The Company performs an assessment on a quarterly basis to assess whether triggering events for impairment exist and to identify any observable price changes. During fiscal 2022, the Company recorded impairment charges of $3.9 million related to investments in non-marketable equity securities. Changes in fair value of non-marketable equity investments are recorded in other (expense) income, net on the consolidated statements of operations. At December 31, 2022 and January 1, 2022, the Company's equity securities without readily determinable fair values totaled $15.1 million and $16.3 million, respectively, and are included in other assets on the consolidated balance sheets.
Financial Instruments and Hedging Activities	Financial Instruments and Hedging Activities The Company utilizes derivative instruments to partially offset its financial risks to foreign exchange risk. The Company does not engage in speculative hedging activity. In order to account for a derivative instrument as a cash flow hedge, specific criteria must be met, including: (i) ensuring at the inception of the hedge that formal documentation exists for both the hedging relationship and the entity’s risk management objective and strategy for undertaking the hedge and (ii) at the inception of the hedge and on an ongoing basis, the hedging relationship is expected to be highly effective in achieving offsetting changes in fair value attributed to the hedged risk during the period that the hedge is designated. Cash flow hedge amounts that are included in the assessment of hedge effectiveness are deferred in accumulated other comprehensive income (loss) until the hedged item is recognized in earnings. Deferred gains and losses associated with cash flow hedges are recognized as a component of net sales in the same period as the related revenue is recognized. Absent meeting these criteria, changes in fair value are recognized in other (expense) income, net, in the consolidated statements of operations. The Company may also enter into non-designated foreign currency contracts to offset a portion of the foreign currency exchange gains and losses generated by the remeasurement of certain assets and liabilities denominated in non-functional currencies. Changes in fair value are recognized in other (expense) income, net, in the consolidated statements of operations.
Fair Value Measurements	Fair Value Measurements The Company accounts for certain assets and liabilities at fair value. The fair value is established based on a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. These tiers include: • Level 1 - observable inputs such as quoted prices for identical instruments in active markets; • Level 2 - inputs other than quoted prices in active markets that are either directly or indirectly observable; and • Level 3 - unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation through recognition of the fair value of the stock-based compensation as a charge against earnings. The Company issues equity incentive awards in the form of restricted stock units ("RSUs") and performance-based restricted stock units ("PSUs"). The fair value for RSUs is based on the closing share price of the Company's common stock on the date of grant. PSUs are aligned to specified performance targets such as financial metrics or the relative returns of the Company's common stock ("TSRs"). The fair value of PSUs aligned to specified performance metrics is determined based on the number of units expected to vest upon achievement of the performance conditions. The fair value for PSUs aligned to the TSR is based on a Monte Carlo simulation model. The Company recognizes stock-based compensation as an expense on a straight-line basis, over the requisite service period. The Company accounts for forfeitures as they occur, rather than applying an estimated forfeiture rate.
Research and Development	Research and Development Costs incurred in the research and development of the Company’s products are expensed as incurred.
Advertising Expense	Advertising ExpenseAdvertising costs are expensed as incurred and included in selling and marketing expenses.
Income Taxes	Income TaxesThe Company accounts for its income taxes using the asset and liability method, under which the Company recognizes the amount of taxes payable or refundable for the current year. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis using enacted tax rates in effect in the years in which those temporary differences are expected to be recovered or settled in each jurisdiction. A valuation allowance is provided if, based upon the weight of available evidence, it is more likely than not that the related benefits will not be realized. In assessing the recoverability of its deferred tax assets, the Company evaluates all available evidence, both positive and negative, to assess whether it is more likely than not that sufficient future taxable income will be generated to permit use of existing deferred tax assets in each taxpaying jurisdiction. For any deferred tax asset that exceeds the amount for which it is more likely than not that the Company will realize a benefit, the Company establishes a valuation allowance. During the third quarter of fiscal 2022, the Company concluded that, based on its evaluation of available positive and negative evidence, it is no longer more likely than not that its net U.S. federal and state deferred tax assets are recoverable. In assessing the realizability of its U.S. deferred tax assets, the key factors used to determine positive and negative evidence included its recent losses resulting in cumulative loss for the three-year period ended December 31, 2022, current macroeconomic trends, and expected future reversals of existing taxable temporary differences. Such objective negative evidence limits the Company's ability to consider other subjective evidence, such as its projections for future growth. Given the weight of objectively verifiable historical losses from the Company's U.S. operations, the Company recorded a valuation allowance of $57.5 million in the third quarter of fiscal 2022 as a reserve against our net U.S. federal and state deferred tax assets. The Company expects to continue to record a valuation allowance against these assets until sufficient positive evidence exists to support its reversal.
Concentration of Credit Risk and Significant Customers	Concentration of Credit Risk and Significant Customers Financial instruments which potentially expose the Company to concentrations of credit risk consist of accounts receivable and cash and cash equivalents. Management believes its credit policies are prudent and reflect normal industry terms and business risk. At December 31, 2022 and January 1, 2022, one customer accounted for 16.6% and 14.5% , respectively, of the Company's accounts receivable balance. For the fiscal years ended December 31, 2022, January 1, 2022, and January 2, 2021, there was one customer that accounted for 10% or more of total revenue, representing 22.6%, 21.8% and 22.7%, of the Company's total revenue, respectively. The Company maintains its cash in bank deposit accounts and money market funds at high quality financial institutions. The individual balances, at times, may exceed federally insured limits. These deposits may be redeemed upon demand, and management believes that the financial institutions that hold the Company’s cash and cash equivalents are financially sound and, accordingly, minimal credit risk exists with respect to cash and cash equivalents. Restructuring Charges During August 2022, the Company initiated a restructuring of its operations designed to better align its cost structure with near-term revenue and cash flow generation ("August 2022 restructuring"). The Company recorded restructuring charges of $5.2 million for employee severance and benefit costs related to the termination of approximately 100 employees, and made severance and benefit payments of approximately $3.6 million resulting from the restructuring during fiscal 2022. These restructuring charges are recorded in the consolidated statement of operations. In October 2022, the Company approved a plan to market portions of its headquarters with the intent to reduce its global office footprint ("Facility restructuring"). During December 2022, the Company executed an agreement to sublease a portion of the space. As a result of the execution of the sublease agreement, the subleased space was considered as one asset group and the Company determined that indicators of impairment existed related to the right-of-use asset and property and equipment associated with the subleased space. Accordingly, the Company conducted an impairment test to assess whether the fair value of the asset group was lower than its carrying value. The results of the impairment test indicated that the fair value of the asset group was lower than its carrying value. The Company determined the fair value of the asset group using a discounted cash flow method. The assumptions used in the discounted cash flow analysis included projected sublease income over the sublease term and a discount rate based on the weighted-average cost of capital. Based on the results of the Company’s assessment, the Company recognized an impairment loss of $3.4 million, of which $2.3 million was allocated to the right-of-use asset and $1.1 million was allocated to property and equipment. This impairment loss is recorded under general and administrative expenses in the consolidated statement of operations for the fiscal year ended December 31, 2022.
Net Income Per Share	Net (loss) income per share:Basic (loss) income per share is calculated using the Company's weighted-average outstanding common shares. Diluted (loss) income per share is calculated using the Company's weighted-average outstanding common shares including the dilutive effect of stock awards as determined under the treasury stock method.
Recent Accounting Pronouncements	Recently Issued Accounting StandardsFrom time to time, new accounting pronouncements are issued by FASB that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption.
Revenue Recognition	For contracts with a duration of greater than one year, the transaction price allocated to performance obligations that are unsatisfied as of December 31, 2022 and January 1, 2022 was $23.2 million and $20.9 million, respectively.The Company’s products generally carry a one-year or two-year limited warranty that promises customers that delivered products are as specified. The Company does not consider these assurance-type warranties as a separate performance obligation and therefore, the Company accounts for such warranties under ASC 460, "Guarantees." For contracts with the right to upgrade to a new product after a specified period of time, the Company accounts for this trade-in right as a guarantee obligation under ASC 460. The total transaction price is reduced by the full amount of the trade-in right's fair value and the remaining transaction price is allocated between the performance obligations within the contract. The Company provides limited rights of returns for direct-to-consumer sales generated through its online stores and certain resellers and distributors. The Company records an allowance for product returns based on specific terms and conditions included in the customer agreements or based on historical experience and the Company's expectation of future returns. In addition, the Company may provide other credits or incentives which are accounted for as variable consideration when estimating the amount of revenue to recognize. Where appropriate, these estimates take into consideration relevant factors such as the Company’s historical experience, current contractual requirements, specific known market events and forecasted inventory level in the channels. Overall, these reserves reflect the Company’s best estimates, and the actual amounts of consideration ultimately received may differ from the Company’s estimates. Returns and credits are estimated at the time of sale and updated at the end of each reporting period as additional information becomes available.
