NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. Description of Business

iRobot Corporation ("iRobot" or the "Company") designs and builds robots that empower people to do more. The Company develops robotic technology and applies it to produce and market consumer robots. The Company’s revenue is primarily generated from product sales through distributor and retail sales channels, as well as its on-line stores.

2. Summary of Significant Accounting Policies

Basis of Presentation

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

In the opinion of management, all adjustments necessary to the unaudited interim consolidated financial statements have been made to state fairly the Company's financial position. Interim results are not necessarily indicative of results for the full fiscal year or any future periods. The information included in this Form 10-Q should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in its Annual Report on Form 10-K for the fiscal year ended December 29, 2018, filed with the Securities and Exchange Commission on February 14, 2019.

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.

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 revenues and expenses. These estimates and judgments, include but are not limited to, revenue recognition, including performance obligations, variable consideration and other obligations such as product returns and incentives; warranty costs; valuation of goodwill and acquired intangible assets; valuation of financial instruments; evaluating loss contingencies; accounting for stock-based compensation including performance-based assessments; and accounting for income taxes and related valuation allowances. The Company bases these estimates and judgments on historical experience, market participant fair value considerations, projected future cash flows and various other factors that the Company believes are reasonable under the circumstances. Actual results may differ from the Company’s estimates.

Other Assets

The Company holds non-marketable equity securities as part of its strategic investments portfolio. The Company classifies its cost method investments as equity securities without readily determinable fair values and measures these investments at cost, less any impairment, adjusted for observable price changes. At June 29, 2019 and December 29, 2018, other assets consisted primarily of equity securities without readily determinable fair values and an equity method investment totaling $21.6 million and $15.1 million, respectively.

Net Income Per Share

Basic income per share is calculated using the Company's weighted-average outstanding common shares. Diluted 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.

iROBOT CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (continued)

The following table presents the calculation of both basic and diluted net income per share (in thousands, except per share amounts): 

	Three Months Ended				Six Months Ended
	June 29, 2019		June 30, 2018		June 29, 2019		June 30, 2018
Net income	$	7,207	$	10,471	$	29,727	$	30,872
Weighted-average common shares outstanding	28,079		27,615		27,970		27,802
Dilutive effect of employee stock awards	684		722		809		856
Diluted weighted-average common shares outstanding	28,763		28,337		28,779		28,658
Basic income per share	$	0.26	$	0.38	$	1.06	$	1.11
Diluted income per share	$	0.25	$	0.37	$	1.03	$	1.08

Employee stock awards representing approximately 0.2 million shares of common stock for the three months ended June 29, 2019 and June 30, 2018, and approximately 0.1 million shares of common stock for the six months ended June 29, 2019 and June 30, 2018, were excluded from the computation of diluted earnings per share as their effect would have been antidilutive.

Recently Adopted Accounting Standards

In June 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-07, "Compensation - Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting (Topic 718)." The amendments in ASU No. 2018-07 expand the scope of Topic 718 to include share-based payments issued to nonemployees for goods or services. The amendments in this ASU are effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods, with early adoption permitted. The Company adopted this standard effective December 30, 2018 which did not have a material impact on the Company's consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02 "Leases." This ASU and subsequently issued amendments require lessees to recognize the assets and liabilities on their balance sheet for the rights and obligations created by most leases and continue to recognize expenses on their income statements over the lease term. The standard also requires disclosures designed to give financial statement users information on the amount, timing and uncertainty of cash flows arising from leases. In July 2018, the FASB issued ASU No. 2018-11, "Leases (Topic 842): Targeted Improvements," which provides an alternative transition method that entities can elect when adopting the new standard. Under this alternative transition method, a company is permitted to use its effective date as the date of initial application without restating comparative period financial statements. The Company adopted the standard effective December 30, 2018 using the alternative transition method which resulted in the recognition of operating lease right-of-use assets and operating lease liabilities of approximately $52.8 million and $67.3 million, respectively. The Company's consolidated financial statements as of and for the three and six months ended June 29, 2019 are presented under the new standard, while the comparative quarter presented is not adjusted and continues to be reported in accordance with the historical accounting policy. See Note 4, "Leases," for the required disclosures related to the impact of adopting this standard and a discussion of the Company's updated policies related to lease accounting.

Recently Issued Accounting Standards

In August 2018, the FASB issued ASU No. 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software." The new standard aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The amendments to this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. Implementation should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently evaluating the impact of the standard on its consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurement: Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement." The amendment modifies disclosure requirements related to fair value measurement. The amendments to this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Implementation on a prospective or retrospective basis varies by specific disclosure requirement. Early adoption is permitted. The standard also allows for early adoption of any removed or modified disclosures upon issuance of this ASU while delaying adoption of the additional disclosures until their effective date. The Company does not believe this amendment will have a material impact on its consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, "Measurement of Credit Losses on Financial Instruments," as clarified in ASU No. 2019-04 and ASU No. 2019-05. The guidance amends the impairment model by requiring entities to use a forward-

iROBOT CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (continued)

looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments. This may result in the earlier recognition of allowances for losses. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of the standards on 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 recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption.

3. Revenue Recognition

The Company primarily derives its revenue from product sales. The Company sells products directly to consumers through on-line stores and indirectly through resellers and distributors. Revenue is recognized upon transfer of control of promised products or services to customers, generally as title and risk of loss passes, in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. 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.

The Company’s product portfolio includes various consumer robots, many of which are Wi-Fi connected. The consumer robots are generally 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, and the revenue is recognized at a point in time when the control is transferred to distributors, resellers or directly to end customers through on-line stores. For consumer robots with Wi-Fi capability ("connected robots"), each sale represents an arrangement with multiple promises consisting of the robot, an app, cloud services and potential future unspecified software upgrades. The Company has determined that the app, cloud services and potential future unspecified software upgrades represent one promised service to the customer to enhance the functionality and interaction with the robot (referred to collectively as "Cloud Services"). For certain connected robots, the Company has concluded that, on a quantitative and qualitative basis, the Cloud Services do not constitute a material performance obligation and, as such, these services are not considered a separate performance obligation that requires allocation of transaction price.

During the third quarter of 2018, the Company launched Roomba i7 and i7+ which brought a new level of intelligence and automation to robotic vacuum cleaners with the ability to learn, map and adapt to a home's floor plan. The Company has concluded that beginning with this launch, the Cloud Services related to these new products are a material performance obligation. For contracts that contain multiple performance obligations, the transaction price is allocated to each performance obligation based on a relative standalone selling price ("SSP"). The SSP reflects the Company's best estimate of what the selling prices of performance obligations would be if they were sold regularly on a standalone basis. Revenue allocated to the robots is recognized at a point in time when control is transferred. Revenue allocated to the Cloud Services is deferred and recognized on a straight-line basis over the estimated period the software upgrades and services are expected to be provided. For contracts with a duration of greater than one year, the transaction price allocated to performance obligations that are unsatisfied as of June 29, 2019 is not material. The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less.

The Company’s products generally carry a one-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."

Significant Judgments

The Company provides limited rights of returns for direct-to-consumer sales generated through its on-line stores and certain resellers and distributors. In addition, the Company may provide other credits or incentives, including price protection, 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 trends and forecasted customer buying and payment patterns. 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 contract inception and updated at the end of each reporting period as additional information becomes available and only to the extent that it is probable that a significant reversal of any incremental revenue will not occur. As of June 29, 2019, the Company has reserves for product returns of $44.5 million and other credits and incentives of $69.7 million. As of December 29, 2018, the Company had reserves for product returns of $53.9 million and other credits and incentives of $97.7 million. Revenue recognized during the three months ended June 29, 2019 and June 30, 2018 related to performance obligations satisfied in a prior period was not material.

Disaggregation of Revenue

The following table provides information about disaggregated revenue by geographical region (in thousands):

	Three Months Ended				Six Months Ended
	June 29, 2019		June 30, 2018		June 29, 2019		June 30, 2018
United States	$	124,472	$	111,526	$	238,537	$	218,388
EMEA	82,893		70,123		157,462		139,710
Other	52,807		44,668		101,834		85,287
Total revenue	$	260,172	$	226,317	$	497,833	$	443,385

Contract Balances

The following table provides information about receivables and contract liabilities from contracts with customers (in thousands):

	June 29, 2019		December 29, 2018
Accounts receivable, net	$	90,401	$	162,166
Contract liabilities	3,075		5,756

The Company invoices customers based upon contractual billing schedules, and accounts receivable are recorded when the right to consideration becomes unconditional. Contract liabilities primarily relate to prepayments received from customers in advance of product shipments. The change in the opening and closing balances of the Company’s contract assets and contract liabilities primarily results from the timing difference between the Company’s performance and the customer’s payment. During the three months ended June 29, 2019 and June 30, 2018, the Company recognized $5.3 million and $6.3 million, respectively, of the contract liability balance as revenue upon transfer of the products to customers. During the six months ended June 29, 2019 and June 30, 2018, the Company recognized $5.8 million and $6.7 million, respectively, of the contract liability balance as revenue upon transfer of the products to customers. The Company does not assess whether a prepayment received represents a significant financing component as the period between when the payment is received and the transfer of the products to the customer is generally one year or less.

4. Leases

The Company's leasing arrangements primarily consist of operating leases for its facilities which include corporate, sales and research and development offices. 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. 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 nonlease 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. 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 existing leases do not provide a readily determinable implicit rate. Therefore, the Company estimates its incremental borrowing rate to discount the lease payments based on information available at December 30, 2018 (date of initial application) or the lease commencement date for existing leases upon adoption or new leases post adoption, respectively. At June 29, 2019, the Company's weighted average discount rate was 3.61%, while the weighted average remaining lease term was 9.58 years.

The components of lease expense were as follows (in thousands):

	Three Months Ended		Six Months Ended
	June 29, 2019
Operating lease cost	$	1,969	$	3,939
Variable lease cost	1,316		2,136

Financial Statement Impact of Adopting ASC 842

The Company adopted ASC 842 effective December 30, 2018 using the alternative transition method. Under this alternative transition method, a company is permitted to use its effective date as the date of initial application without restating comparative period financial statements. The Company elected the package of practical expedients permitted under the transition guidance, which allowed the Company to carryforward its historical assessments of (1) whether contracts are or contain leases, (2) lease classification and (3) initial direct costs. In addition, the Company elected the practical expedient to use hindsight in determining lease term. The adoption of the new standard resulted in the recognition of right-of-use assets and lease liabilities of approximately $52.8 million and $67.3 million, respectively. The standard did not materially impact the Company's consolidated income or cash flows.

8. Derivative Instruments

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 Japanese Yen, Canadian Dollar, British Pound and the Euro. The Company uses derivative instruments that are designated in cash flow hedge relationships to reduce or eliminate the effects of foreign exchange rate changes on sales and purchases. These contracts typically have maturities of thirty-seven months or less. At June 29, 2019 and December 29, 2018, the Company had outstanding cash flow hedges with a total notional value of $389.9 million and $366.7 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 ten months or less. At June 29, 2019 and December 29, 2018, the Company had outstanding economic hedges with a total notional value of $48.0 million and $56.0 million, respectively.

The fair values of derivative instruments are as follows (in thousands):

(2) Level 3 fair value estimates are based on inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques, including option pricing and discounted cash flow models. Unobservable inputs used in the models are significant to the fair values of the assets and liabilities.

(3) As of June 29, 2019, the Company’s investments had maturity dates ranging from August 2019 to March 2021.

10. Stockholders' Equity

Share Repurchase Activity

On February 27, 2018, the Company's board of directors approved a stock repurchase program authorizing up to $50.0 million in share repurchases. This share repurchase program commenced on March 28, 2018 with an expiration date of December 28, 2018. As of June 30, 2018, the Company completed the repurchase program and repurchased 798,794 shares of common stock totaling $50.0 million.

11. 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

At June 29, 2019, the Company had outstanding purchase orders aggregating approximately $213.0 million. These purchase orders, the majority of which are with contract manufacturers for the purchase of inventory in the normal course of business, are for manufacturing and non-manufacturing related goods and services, and are generally cancelable without penalty. In circumstances where the Company determines that it has financial exposure associated with any of these commitments, the Company records a liability in the period in which that exposure is identified.

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 June 29, 2019 and December 29, 2018, 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):

	Three Months Ended						Six Months Ended

12. Income Taxes

The Company’s effective income tax rate for the three months ended June 29, 2019 and June 30, 2018, was (6.3)% and 29.6%, respectively. The decrease in the effective income tax rate was primarily due to increased tax benefits related to excess stock-based compensation and the recognition of a discrete tax benefit upon the effective settlement of a foreign tax audit in the three months ended June 29, 2019. In addition, the Company recorded a discrete charge for estimated taxes associated with a restructuring of the EMEA business in the three months ended June 30, 2018.

The Company's effective income tax rate of (6.3)% for the three months ended June 29, 2019 differed from the federal statutory tax rate of 21% primarily due to the recognition of tax benefits related to excess stock-based compensation and the recognition of a discrete tax benefit upon the effective settlement of a foreign tax audit.

iROBOT CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (continued)

The Company’s effective income tax rate for the six months ended June 29, 2019 and June 30, 2018, was 2.0% and 24.3%, respectively. The decrease in the effective income tax rate was primarily due to increased tax benefits related to excess stock-based compensation and a decrease in foreign taxes related to a discrete charge for estimated taxes associated with a restructuring of the EMEA business in the three months ended June 30, 2018.

The Company's effective income tax rate of 2.0% for the six months ended June 29, 2019 differed from the federal statutory tax rate of 21% primarily due to the recognition of tax benefits related to excess stock-based compensation.

13. Industry Segment, Geographic Information and Significant Customers

The Company operates as one operating segment. The Company's consumer robots products are offered to consumers through distributor and retail sales channels, as well as its on-line stores.

Significant Customers

For the three months ended June 29, 2019 and June 30, 2018, the Company generated 28.0% and 23.8% of total revenue, respectively, from one of its retailers (Amazon).

For the six months ended June 29, 2019 and June 30, 2018, the Company generated 22.3% and 17.7% of total revenue, respectively, from one of its retailers (Amazon).

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The information contained in this section has been derived from our consolidated financial statements and should be read together with our consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q.

Overview

iRobot is a leading consumer robot company that designs and builds robots that empower people to do more both inside and outside of the home. Our consumer robots help people find smarter ways to clean and accomplish more in their daily lives. Our portfolio of solutions features proprietary technologies for the connected home and advanced concepts in cleaning, mapping and navigation, human-robot interaction and physical solutions. Leveraging this portfolio, our engineers are building an ecosystem of robots to empower the smart home. For more than 25 years, we have been a pioneer in the robotics and consumer products industries. We sell our robots through a variety of distribution channels, including chain stores and other national retailers, through our on-line store, and through value-added distributors and resellers worldwide.

As of June 29, 2019, we had 1,120 full-time employees. We have developed expertise in the disciplines necessary to build durable, high-performance and cost-effective robots through the close integration of software, electronics and hardware. Our core technologies serve as reusable building blocks that we adapt and expand to enhance existing products, develop next-generation versions of our products and design and launch new products, reducing the time, cost and risk associated with product development. Our significant expertise in consumer needs, robot design, engineering and smart home technologies and trends positions us to capitalize on the growth we expect in the market for robot-based consumer products.

19

Our continued success depends upon our ability to respond to a number of challenges in the consumer robots market. We believe the most significant of these include increasing competition and our ability to successfully develop and introduce products and product enhancements into both new and existing markets.

In the third quarter of 2018, we introduced the Roomba i7 and i7+ in the U.S., which are robot vacuums that remember a home's floor plan and clean specific rooms by name. Using Imprint™ Smart Mapping, the Roomba i7+ learns the home's floor plan, giving customers total control over which rooms to clean and when. When the Roomba i7+ robot vacuum is finished cleaning, it empties its own dust bin into the Clean Base™, which holds 30 bins of dirt. In the third quarter of 2018, the Company also introduced the Roomba e5, a highly-featured product at a more accessible price, to our lineup in the U.S. In the fourth quarter of 2018, we introduced the Roomba e5 in markets outside of the U.S. in advance of the holiday season.

During the first quarter of 2019, we launched Roomba i7 and i7+ in EMEA, Japan and China. During the second quarter of 2019, we successfully launched two new cleaning robots in the U.S., the Roomba s9 and s9+, which, along with the features of the Roomba i7 and i7+, are robot vacuums that can clean deep into corners and along edges, and the Braava jet m6 robot mop, which can tackle multiple rooms and large spaces with advanced navigation and mapping capabilities. Together, these two robots can use Imprint Link Technology to talk to each other, automatically vacuuming and then mopping without additional action by the user. We anticipate that the s9 and s9+ will be launched in EMEA in the third quarter of 2019 and in all other target markets in early 2020. We anticipate that the m6 will be launched in all target markets during the second half of 2019.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses. These estimates and judgments, include but are not limited to, revenue recognition including performance obligations, variable consideration and other obligations such as product returns and incentives; warranty costs, valuation of goodwill and acquired intangible assets; evaluating loss contingencies; accounting for stock-based compensation including performance-based assessments; and accounting for income taxes and related valuation allowances. We base these estimates and judgments on historical experience, market participant fair value considerations, projected future cash flows and various other factors that we believe are reasonable under the circumstances. Actual results may differ from our estimates. Additional information about these critical accounting policies may be found in the "Management’s Discussion and Analysis of Financial Condition and Results of Operations" section included in our Annual Report on Form 10-K for the fiscal year ended December 29, 2018.

Effective December 30, 2018, we adopted the new leasing standard under ASC 842 using the alternative transition method. The adoption of the new standard resulted in a material increase in the assets and liabilities, while the impact on the Company's results of operations and cash flows was not material for the three and six months ended June 29, 2019. We have updated our accounting policy as it relates to lease accounting. Refer to Note 4 of the consolidated financial statements.

Gross margin decreased to 45.4% in the three months ended June 29, 2019 compared to 52.1% in the three months ended June 30, 2018. The decrease in gross margin is primarily related to increased pricing and promotional activity in our international markets, most notably EMEA, as well as the increased tariffs on our Roomba products imported to the United States from China.

Gross margin decreased to 47.8% in the six months ended June 29, 2019 compared to 52.7% in the six months ended June 30, 2018.

This increase is primarily due to an increase in people-related costs of $2.5 million resulting from increased headcount, offset by lower program-related cost of $1.8 million during the three months ended June 29, 2019.

Research and development expenses increased $3.1 million, or 4.5%, to $70.9 million (14.2% of revenue) in the six months ended June 29, 2019 from $67.9 million (15.3% of revenue) in the six months ended June 30, 2018.

This increase was primarily attributable to an increase in marketing investments totaling $8.7 million to support our new product launches in the U.S. and certain promotional and advertising campaigns in the US. and abroad as well as higher people-related costs of $1.3 million.

Selling and marketing expenses increased by $18.0 million, or 23.3%, to $95.2 million (19.2% of revenue) in the six months ended June 29, 2019 from $77.2 million (17.5% of revenue) in the six months ended June 30, 2018. This increase was primarily attributable to an increase in marketing investments totaling $13.8 million to support our new product launches and certain promotional and advertising campaigns in all regions as well as higher people-related costs of $3.1 million.

Effective income tax rate	(6.3		)%	29.6		%						2.0		%	24.3		%

We recorded an income tax benefit of $(0.4) million and income tax expense of $4.4 million for the three months ended June 29, 2019 and June 30, 2018, respectively. The $(0.4) million income tax benefit for the three months ended June 29, 2019 resulted in an effective income tax rate of (6.3)%. The $4.4 million income tax expense for the three months ended June 30, 2018 resulted in an effective income tax rate of 29.6%. The decrease in the effective income tax rate was primarily due to increased tax benefits related to excess stock-based compensation and the recognition of a discrete tax benefit upon the effective settlement of a foreign tax audit in the three months ended June 29, 2019. In addition, we recorded a discrete charge for estimated taxes associated with a restructuring of the EMEA business in the three months ended June 30, 2018.

Our effective income tax rate of (6.3)% for the three months ended June 29, 2019 differed from the federal statutory tax rate of 21% primarily due to the recognition of tax benefits related to excess stock-based compensation and the recognition of a discrete tax benefit upon the effective settlement of a foreign tax audit.

We recorded an income tax expense of $0.6 million and $9.9 million for the six months ended June 29, 2019 and June 30, 2018, respectively. The $0.6 million income tax expense for the six months ended June 29, 2019 resulted in an effective income tax rate of 2.0%. The $9.9 million income tax expense for the six months ended June 30, 2018 resulted in an effective income tax rate of 24.3%. The decrease in the effective income tax rate was primarily due to increased tax benefits related to excess stock-based compensation and a decrease in foreign taxes related to a discrete charge for estimated taxes associated with a restructuring of the EMEA business recorded in the six months ended June 30, 2018.

Our effective income tax rate of 2.0% for the six months ended June 29, 2019 differed from the federal statutory tax rate of 21% primarily due to the recognition of tax benefits related to excess stock-based compensation.

Liquidity and Capital Resources

At June 29, 2019, our principal sources of liquidity were cash and cash equivalents totaling $132.8 million and short-term investments of $24.0 million. Our working capital, which represents our total current assets less total current liabilities, was $328.6 million as of June 29, 2019, compared to $227.7 million as of June 30, 2018.

We manufacture and distribute our products through contract manufacturers and third-party logistics providers. We believe this approach gives us the advantages of relatively low capital investment and significant flexibility in scheduling production and managing inventory levels. By leasing our office facilities, we also minimize the cash needed for expansion. Accordingly, our capital spending is generally limited to leasehold improvements, computers, office furniture, product-specific production tooling, internal use software and test equipment. In the six months ended June 29, 2019 and June 30, 2018, we spent $14.7 million and $14.3 million, respectively, on capital expenditures.

Our strategy for delivering consumer products to our distributors and retail customers gives us the flexibility to provide container shipments directly from our contract manufacturers in Southern China to our customers and, alternatively, allows our distributors and certain retail customers to take possession of product on a domestic basis. Accordingly, our consumer product

24

inventory consists of goods shipped to our third-party logistics providers for the fulfillment of distributor, retail and direct-to-consumer sales. Our contract manufacturers are also responsible for purchasing and stocking components required for the production of our products, and they typically invoice us when the finished goods are shipped.

Cash provided by operating activities

Net cash provided by operating activities for the six months ended June 29, 2019 was $21.3 million, of which the principal components were our net income of $29.7 million, non-cash charges of $36.0 million and changes in working capital. The change in working capital mainly includes a decrease in accounts receivable of $67.8 million, partially offset by a decrease in accounts payable and accrued expenses of $70.9 million and increases in inventory and other current assets of $27.1 million and $14.2 million, respectively.

Cash used in investing activities

Net cash used in investing activities for the six months ended June 29, 2019 was $16.2 million. During the six months ended June 29, 2019, we invested $14.7 million in the purchase of property and equipment, including machinery and tooling for new products. In addition, we made strategic investments of $4.5 million and paid $2.8 million for a business acquisition, while sales and maturities of marketable securities amounted to $5.9 million.

Cash used in financing activities

Net cash used in financing activities for the six months ended June 29, 2019 was $2.6 million. During the six months ended June 29, 2019, we received $4.7 million from employee stock plans and paid $7.3 million upon vesting of restricted stock where 59,260 shares were retained by us to cover employee tax withholdings.

Working Capital Facilities

Credit Facility

In June 2018, we entered into a new agreement with Bank of America, N.A., increasing the amount of our unsecured revolving line of credit from $75.0 million to $150.0 million extending the term of the credit facilities to June 2023. As of June 29, 2019, we had no outstanding borrowings under our revolving credit facility. The revolving line of credit is available to fund working capital and other corporate purposes. The interest on loans under our credit facility accrues, at our election, at either (1) LIBOR plus a margin, currently equal to 1.0%, based on our ratio of indebtedness to Adjusted EBITDA (the "Eurodollar Rate"), or (2) the lender’s base rate. The lender’s base rate is equal to the highest of (1) the federal funds rate plus 0.5%, (2) the lender’s prime rate and (3) the Eurodollar Rate plus 1.0%. In the event that LIBOR is discontinued as expected in 2021, we expect the interest rates for our debt following such event will be based on either alternate base rates or agreed upon replacement rates. While we do not expect a LIBOR discontinuation would affect our ability to borrow or maintain already outstanding borrowings, it could result in higher interest rates.

This 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. In addition, we are required to meet certain financial covenants customary with this type of agreement, including maintaining a maximum ratio of indebtedness to Adjusted EBITDA and a minimum specified interest coverage ratio.

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

As of June 29, 2019, we were in compliance with all covenants under the revolving credit facility.

Working Capital and Capital Expenditure Needs

We currently have no material cash commitments, except for normal recurring trade payables, expense accruals, capital expenditures and operating leases, all of which we anticipate funding through working capital, funds provided by operating activities and our existing revolving line of credit. We believe our outsourced approach to manufacturing provides us with flexibility in both managing inventory levels and financing our inventory. We believe our existing cash and cash equivalents, short-term investments, cash provided by operating activities, and funds available through our revolving line of credit will be sufficient to meet our working capital and capital expenditure needs over at least the next twelve months. In the event our revenue plan does not meet our expectations, we may eliminate or curtail expenditures to mitigate the impact on our working capital. Our future capital requirements will depend on many factors, including our rate of revenue growth, the expansion of our marketing and sales activities, the timing and extent of spending to support product development efforts, the timing of introductions of new products and enhancements to existing products, the acquisition of new capabilities or technologies, and the continuing market acceptance of our products and services. Moreover, to the extent existing cash and cash equivalents,

25

short-term investments, cash from operations, and cash from short-term borrowing are insufficient to fund our future activities, we may need to raise additional funds through public or private equity or debt financing. As part of our business strategy, we may consider additional acquisitions of companies, technologies and products, which could also require us to seek additional equity or debt financing. Additional funds may not be available on terms favorable to us or at all.

Contractual Obligations

The disclosure of our contractual obligations and commitments is set forth under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations - Contractual Obligations" in our Annual Report on Form 10-K for the year ended December 29, 2018. Our principal commitments generally consist of obligations under our credit facility, leases for office space and minimum purchase commitments for services such as cloud support and other non-cancelable contractual obligations for subscription software services. There have been no material changes in our contractual obligations and commitments since December 29, 2018.

Off-Balance Sheet Arrangements

As of June 29, 2019, we had no off-balance sheet arrangements as defined in Item 303(a)(4) of Regulation S-K.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

Exchange Rate Sensitivity

Our international revenue and expenses are denominated in multiple currencies, including Japanese Yen, Canadian Dollars, Chinese Renminbi, British Pounds and Euros. As such, we have exposure to adverse changes in exchange rates associated with the revenue and operating expenses of our foreign operations. Any fluctuations in other currencies will have minimal direct impact on our international revenue.

In addition to international business conducted in foreign currencies, we have international revenue denominated in U.S. dollars. As the U.S. dollar strengthens or weakens against other currencies, our international distributors may be impacted, which could affect their profitability and our ability to maintain current pricing levels on our international consumer products.

We regularly monitor the forecast of non-U.S. dollar revenue and expenses and the level of non-U.S. dollar monetary asset and liability balances to determine if any actions, including possibly entering into foreign currency contracts should be taken to minimize the impact of fluctuating exchange rates on our results of operations. Periodically, we enter into forward exchange contracts to hedge against foreign currency fluctuations. These contracts may or may not be designated as cash flow hedges for accounting purposes. We use cash flow hedges primarily to reduce the effects of foreign exchange rate changes on sales primarily in Japanese Yen and Euros. At June 29, 2019 and December 29, 2018, we had outstanding cash flow hedges with a total notional value of $389.9 million and $366.7 million, respectively.

We also enter 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 have maturities of ten months or less. At June 29, 2019 and December 29, 2018, we had outstanding economic hedges with a total notional value of $48.0 million and $56.0 million, respectively.

At June 29, 2019, assuming all other variables are constant, if the U.S. Dollar weakened or strengthened by 10%, the fair market value of our foreign currency contracts would increase or decrease by approximately $45.9 million.

Item 4. Controls and Procedures

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

26

are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

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

Part II. Other Information

Item 1. Legal Proceedings

From time to time and in the ordinary course of business, we are subject to various claims, charges and litigation. The outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to us, which could materially affect our financial condition or results of operations.

Item 1A. Risk Factors

We operate in a rapidly changing environment that involves a number of risks that could materially affect our business, financial condition or future results, some of which are beyond our control. In addition to the other information set forth in this report, the risks and uncertainties that we believe are most important for you to consider are discussed in Part I, "Item 1A. Risk Factors" in our Annual Report on Form 10-K for the year ended December 29, 2018, which could materially affect our business, financial condition or future results. Additional risks and uncertainties not presently known to us, which we currently deem immaterial or which are similar to those faced by other companies in our industry or business in general, may also impair our business operations. There are no material changes to the Risk Factors described in our Annual Report on Form 10-K for the year ended December 29, 2018, other than updates regarding the tariff increase as set forth in the following:

Significant developments from the recent and potential changes in U.S. trade policies have had, and we expect will continue to have, a material adverse effect on our business, financial condition and results of operations.

The U.S. government has indicated its intent to alter its approach to international trade policy and in some cases to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements and treaties with foreign countries. Effective September 24, 2018, the U.S. government implemented a 10% tariff on certain goods imported from China, which include the majority of those imported by the Company. These tariffs were increased to 25% on May 10, 2019. In addition, the U.S. government has indicated a desire to implement tariffs on the remainder of the goods the Company imports from China, although the timing of such an increase is unpredictable.  These tariffs, and other governmental action relating to international trade agreements or policies, have adversely impacted demand for our products, our costs, customers, suppliers, distributors, resellers and/or the U.S. economy or certain sectors thereof and, as a result, have adversely impacted, and we expect will continue to adversely impact, our business, financial condition and results of operations. The already-implemented, and any additional or increased, tariffs have caused and may in the future cause us to further increase prices to our customers which we believe has reduced, and in the future may reduce, demand for our products.  Any such price increase, may not be sufficient to fully offset the impact of the tariffs, result in lowering our margin on products sold, as was the case during the first half of 2019 and we expect going forward. It remains unclear what the U.S. or foreign governments will or will not do with respect to tariffs, international trade agreements and policies on a short-term or long-term basis. We cannot predict future trade policy or the terms of any renegotiated trade agreements and their impacts on our business. The adoption and expansion of trade restrictions, the occurrence of a trade war, or other governmental action related to tariffs or trade agreements or policies has the potential to further adversely impact demand for our products, our costs, our customers, our suppliers, and the U.S. economy, which in turn could further adversely impact our business, financial condition and results of operations.

Item 5. Other Information

Our policy governing transactions in our securities by our directors, officers, and employees permits our officers, directors, funds affiliated with our directors, and certain other persons to enter into trading plans complying with Rule 10b5-l under the Exchange Act. We have been advised that certain of our officers and directors (including Colin Angle, Chief Executive Officer, Russell Campanello, EVP, Human Resources and Corporate Communications, Christian Cerda, Chief Operating Officer, Glen Weinstein, EVP & Chief Legal Officer, as well as Mohamad Ali, Deborah Ellinger, Ruey-bin Kao, Andrew Miller and Michelle Stacy, each a director of the Company) have entered into trading plans (each a "Plan" and collectively, the "Plans") covering periods after the date of this quarterly report on Form 10-Q in accordance with Rule 10b5-1 and our policy governing transactions in our securities. Generally, under these trading plans, the individual relinquishes control over the transactions once the trading plan is put into place. Accordingly, sales under these plans may occur at any time, including possibly before, simultaneously with, or immediately after significant events involving our company.

We anticipate that, as permitted by Rule 10b5-l and our policy governing transactions in our securities, some or all of our officers, directors and employees may establish trading plans in the future. We intend to disclose the names of our executive officers and directors who establish a trading plan in compliance with Rule 10b5-1 and the requirements of our policy governing transactions in our securities in our future quarterly and annual reports on Form 10-Q and 10-K filed with the Securities and Exchange Commission. We undertake no obligation to update or revise the information provided herein.

Summary of Significant Accounting Policies

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 balances and transactions. iRobot has prepared the accompanying unaudited consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP"). In addition, certain prior year amounts have been reclassified to conform to the current year presentation.

In the opinion of management, all adjustments necessary to the unaudited interim consolidated financial statements have been made to state fairly the Company's financial position. Interim results are not necessarily indicative of results for the full fiscal year or any future periods. The information included in this Form 10-Q should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in its Annual Report on Form 10-K for the fiscal year ended December 29, 2018, filed with the Securities and Exchange Commission on February 14, 2019.

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.

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 revenues and expenses. These estimates and judgments, include but are not limited to, revenue recognition, including performance obligations, variable consideration and other obligations such as product returns and incentives; warranty costs; valuation of goodwill and acquired intangible assets; valuation of financial instruments; evaluating loss contingencies; accounting for stock-based compensation including performance-based assessments; and accounting for income taxes and related valuation allowances. The Company bases these estimates and judgments on historical experience, market participant fair value considerations, projected future cash flows and various other factors that the Company believes are reasonable under the circumstances. Actual results may differ from the Company’s estimates.

Other Assets

The Company holds non-marketable equity securities as part of its strategic investments portfolio. The Company classifies its cost method investments as equity securities without readily determinable fair values and measures these investments at cost, less any impairment, adjusted for observable price changes. At June 29, 2019 and December 29, 2018, other assets consisted primarily of equity securities without readily determinable fair values and an equity method investment totaling $21.6 million and $15.1 million, respectively.

Net Income Per Share

Basic income per share is calculated using the Company's weighted-average outstanding common shares. Diluted 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.

The following table presents the calculation of both basic and diluted net income per share (in thousands, except per share amounts): 

	Three Months Ended				Six Months Ended
	June 29, 2019		June 30, 2018		June 29, 2019		June 30, 2018
Net income	$	7,207	$	10,471	$	29,727	$	30,872
Weighted-average common shares outstanding	28,079		27,615		27,970		27,802
Dilutive effect of employee stock awards	684		722		809		856
Diluted weighted-average common shares outstanding	28,763		28,337		28,779		28,658
Basic income per share	$	0.26	$	0.38	$	1.06	$	1.11
Diluted income per share	$	0.25	$	0.37	$	1.03	$	1.08

Employee stock awards representing approximately 0.2 million shares of common stock for the three months ended June 29, 2019 and June 30, 2018, and approximately 0.1 million shares of common stock for the six months ended June 29, 2019 and June 30, 2018, were excluded from the computation of diluted earnings per share as their effect would have been antidilutive.

Recently Adopted Accounting Standards

In June 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-07, "Compensation - Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting (Topic 718)." The amendments in ASU No. 2018-07 expand the scope of Topic 718 to include share-based payments issued to nonemployees for goods or services. The amendments in this ASU are effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods, with early adoption permitted. The Company adopted this standard effective December 30, 2018 which did not have a material impact on the Company's consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02 "Leases." This ASU and subsequently issued amendments require lessees to recognize the assets and liabilities on their balance sheet for the rights and obligations created by most leases and continue to recognize expenses on their income statements over the lease term. The standard also requires disclosures designed to give financial statement users information on the amount, timing and uncertainty of cash flows arising from leases. In July 2018, the FASB issued ASU No. 2018-11, "Leases (Topic 842): Targeted Improvements," which provides an alternative transition method that entities can elect when adopting the new standard. Under this alternative transition method, a company is permitted to use its effective date as the date of initial application without restating comparative period financial statements. The Company adopted the standard effective December 30, 2018 using the alternative transition method which resulted in the recognition of operating lease right-of-use assets and operating lease liabilities of approximately $52.8 million and $67.3 million, respectively. The Company's consolidated financial statements as of and for the three and six months ended June 29, 2019 are presented under the new standard, while the comparative quarter presented is not adjusted and continues to be reported in accordance with the historical accounting policy. See Note 4, "Leases," for the required disclosures related to the impact of adopting this standard and a discussion of the Company's updated policies related to lease accounting.

Recently Issued Accounting Standards

In August 2018, the FASB issued ASU No. 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software." The new standard aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The amendments to this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. Implementation should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently evaluating the impact of the standard on its consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurement: Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement." The amendment modifies disclosure requirements related to fair value measurement. The amendments to this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Implementation on a prospective or retrospective basis varies by specific disclosure requirement. Early adoption is permitted. The standard also allows for early adoption of any removed or modified disclosures upon issuance of this ASU while delaying adoption of the additional disclosures until their effective date. The Company does not believe this amendment will have a material impact on its consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, "Measurement of Credit Losses on Financial Instruments," as clarified in ASU No. 2019-04 and ASU No. 2019-05. The guidance amends the impairment model by requiring entities to use a forward-

looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments. This may result in the earlier recognition of allowances for losses. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of the standards on 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 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 (Notes)

6 Months Ended

Revenue Recognition and Deferred Revenue [Abstract]

Revenue from Contract with Customer [Text Block]

Revenue Recognition

The Company primarily derives its revenue from product sales. The Company sells products directly to consumers through on-line stores and indirectly through resellers and distributors. Revenue is recognized upon transfer of control of promised products or services to customers, generally as title and risk of loss passes, in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. 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.

The Company’s product portfolio includes various consumer robots, many of which are Wi-Fi connected. The consumer robots are generally 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, and the revenue is recognized at a point in time when the control is transferred to distributors, resellers or directly to end customers through on-line stores. For consumer robots with Wi-Fi capability ("connected robots"), each sale represents an arrangement with multiple promises consisting of the robot, an app, cloud services and potential future unspecified software upgrades. The Company has determined that the app, cloud services and potential future unspecified software upgrades represent one promised service to the customer to enhance the functionality and interaction with the robot (referred to collectively as "Cloud Services"). For certain connected robots, the Company has concluded that, on a quantitative and qualitative basis, the Cloud Services do not constitute a material performance obligation and, as such, these services are not considered a separate performance obligation that requires allocation of transaction price.

During the third quarter of 2018, the Company launched Roomba i7 and i7+ which brought a new level of intelligence and automation to robotic vacuum cleaners with the ability to learn, map and adapt to a home's floor plan. The Company has concluded that beginning with this launch, the Cloud Services related to these new products are a material performance obligation. For contracts that contain multiple performance obligations, the transaction price is allocated to each performance obligation based on a relative standalone selling price ("SSP"). The SSP reflects the Company's best estimate of what the selling prices of performance obligations would be if they were sold regularly on a standalone basis. Revenue allocated to the robots is recognized at a point in time when control is transferred. Revenue allocated to the Cloud Services is deferred and recognized on a straight-line basis over the estimated period the software upgrades and services are expected to be provided. For contracts with a duration of greater than one year, the transaction price allocated to performance obligations that are unsatisfied as of June 29, 2019 is not material. The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less.

The Company’s products generally carry a one-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."

Significant Judgments

The Company provides limited rights of returns for direct-to-consumer sales generated through its on-line stores and certain resellers and distributors. In addition, the Company may provide other credits or incentives, including price protection, 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 trends and forecasted customer buying and payment patterns. 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 contract inception and updated at the end of each reporting period as additional information becomes available and only to the extent that it is probable that a significant reversal of any incremental revenue will not occur. As of June 29, 2019, the Company has reserves for product returns of $44.5 million and other credits and incentives of $69.7 million. As of December 29, 2018, the Company had reserves for product returns of $53.9 million and other credits and incentives of $97.7 million. Revenue recognized during the three months ended June 29, 2019 and June 30, 2018 related to performance obligations satisfied in a prior period was not material.

Disaggregation of Revenue

The following table provides information about disaggregated revenue by geographical region (in thousands):

	Three Months Ended				Six Months Ended
	June 29, 2019		June 30, 2018		June 29, 2019		June 30, 2018
United States	$	124,472	$	111,526	$	238,537	$	218,388
EMEA	82,893		70,123		157,462		139,710
Other	52,807		44,668		101,834		85,287
Total revenue	$	260,172	$	226,317	$	497,833	$	443,385

Contract Balances

The following table provides information about receivables and contract liabilities from contracts with customers (in thousands):

	June 29, 2019		December 29, 2018
Accounts receivable, net	$	90,401	$	162,166
Contract liabilities	3,075		5,756

The Company invoices customers based upon contractual billing schedules, and accounts receivable are recorded when the right to consideration becomes unconditional. Contract liabilities primarily relate to prepayments received from customers in advance of product shipments. The change in the opening and closing balances of the Company’s contract assets and contract liabilities primarily results from the timing difference between the Company’s performance and the customer’s payment. During the three months ended June 29, 2019 and June 30, 2018, the Company recognized $5.3 million and $6.3 million, respectively, of the contract liability balance as revenue upon transfer of the products to customers. During the six months ended June 29, 2019 and June 30, 2018, the Company recognized $5.8 million and $6.7 million, respectively, of the contract liability balance as revenue upon transfer of the products to customers. The Company does not assess whether a prepayment received represents a significant financing component as the period between when the payment is received and the transfer of the products to the customer is generally one year or less.

Leases (Notes)

Leases [Abstract]

Lessee, Operating Leases [Text Block]

Leases

The Company's leasing arrangements primarily consist of operating leases for its facilities which include corporate, sales and research and development offices. 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. 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 nonlease 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. 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 existing leases do not provide a readily determinable implicit rate. Therefore, the Company estimates its incremental borrowing rate to discount the lease payments based on information available at December 30, 2018 (date of initial application) or the lease commencement date for existing leases upon adoption or new leases post adoption, respectively. At June 29, 2019, the Company's weighted average discount rate was 3.61%, while the weighted average remaining lease term was 9.58 years.

The components of lease expense were as follows (in thousands):

	Three Months Ended		Six Months Ended
	June 29, 2019
Operating lease cost	$	1,969	$	3,939
Variable lease cost	1,316		2,136

Present value of future minimum lease payments	$	63,590
Less: current portion of operating lease liabilities (Note 7)	5,522
Long-term lease liabilities	$	58,068

Financial Statement Impact of Adopting ASC 842

The Company adopted ASC 842 effective December 30, 2018 using the alternative transition method. Under this alternative transition method, a company is permitted to use its effective date as the date of initial application without restating comparative period financial statements. The Company elected the package of practical expedients permitted under the transition guidance, which allowed the Company to carryforward its historical assessments of (1) whether contracts are or contain leases, (2) lease classification and (3) initial direct costs. In addition, the Company elected the practical expedient to use hindsight in determining lease term. The adoption of the new standard resulted in the recognition of right-of-use assets and lease liabilities of approximately $52.8 million and $67.3 million, respectively. The standard did not materially impact the Company's consolidated income or cash flows.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

Derivative Instruments

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 Japanese Yen, Canadian Dollar, British Pound and the Euro. The Company uses derivative instruments that are designated in cash flow hedge relationships to reduce or eliminate the effects of foreign exchange rate changes on sales and purchases. These contracts typically have maturities of thirty-seven months or less. At June 29, 2019 and December 29, 2018, the Company had outstanding cash flow hedges with a total notional value of $389.9 million and $366.7 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 ten months or less. At June 29, 2019 and December 29, 2018, the Company had outstanding economic hedges with a total notional value of $48.0 million and $56.0 million, respectively.

The fair values of derivative instruments are as follows (in thousands):

(1) Level 2 fair value estimates are based on observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

(2) Level 3 fair value estimates are based on inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques, including option pricing and discounted cash flow models. Unobservable inputs used in the models are significant to the fair values of the assets and liabilities.

(3) As of June 29, 2019, the Company’s investments had maturity dates ranging from August 2019 to March 2021.

Commitments and Contingencies

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

At June 29, 2019, the Company had outstanding purchase orders aggregating approximately $213.0 million. These purchase orders, the majority of which are with contract manufacturers for the purchase of inventory in the normal course of business, are for manufacturing and non-manufacturing related goods and services, and are generally cancelable without penalty. In circumstances where the Company determines that it has financial exposure associated with any of these commitments, the Company records a liability in the period in which that exposure is identified.

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 June 29, 2019 and December 29, 2018, 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):

Income Taxes

The Company’s effective income tax rate for the three months ended June 29, 2019 and June 30, 2018, was (6.3)% and 29.6%, respectively. The decrease in the effective income tax rate was primarily due to increased tax benefits related to excess stock-based compensation and the recognition of a discrete tax benefit upon the effective settlement of a foreign tax audit in the three months ended June 29, 2019. In addition, the Company recorded a discrete charge for estimated taxes associated with a restructuring of the EMEA business in the three months ended June 30, 2018.

The Company's effective income tax rate of (6.3)% for the three months ended June 29, 2019 differed from the federal statutory tax rate of 21% primarily due to the recognition of tax benefits related to excess stock-based compensation and the recognition of a discrete tax benefit upon the effective settlement of a foreign tax audit.

The Company’s effective income tax rate for the six months ended June 29, 2019 and June 30, 2018, was 2.0% and 24.3%, respectively. The decrease in the effective income tax rate was primarily due to increased tax benefits related to excess stock-based compensation and a decrease in foreign taxes related to a discrete charge for estimated taxes associated with a restructuring of the EMEA business in the three months ended June 30, 2018.

The Company's effective income tax rate of 2.0% for the six months ended June 29, 2019 differed from the federal statutory tax rate of 21% primarily due to the recognition of tax benefits related to excess stock-based compensation.

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 balances and transactions. iRobot has prepared the accompanying unaudited consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP"). In addition, certain prior year amounts have been reclassified to conform to the current year presentation.

In the opinion of management, all adjustments necessary to the unaudited interim consolidated financial statements have been made to state fairly the Company's financial position. Interim results are not necessarily indicative of results for the full fiscal year or any future periods. The information included in this Form 10-Q should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in its Annual Report on Form 10-K for the fiscal year ended December 29, 2018, filed with the Securities and Exchange Commission on February 14, 2019.

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.

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 revenues and expenses. These estimates and judgments, include but are not limited to, revenue recognition, including performance obligations, variable consideration and other obligations such as product returns and incentives; warranty costs; valuation of goodwill and acquired intangible assets; valuation of financial instruments; evaluating loss contingencies; accounting for stock-based compensation including performance-based assessments; and accounting for income taxes and related valuation allowances. The Company bases these estimates and judgments on historical experience, market participant fair value considerations, projected future cash flows and various other factors that the Company believes are reasonable under the circumstances. Actual results may differ from the Company’s estimates.

Investment, Policy [Policy Text Block]

Other Assets

The Company holds non-marketable equity securities as part of its strategic investments portfolio. The Company classifies its cost method investments as equity securities without readily determinable fair values and measures these investments at cost, less any impairment, adjusted for observable price changes. At June 29, 2019 and December 29, 2018, other assets consisted primarily of equity securities without readily determinable fair values and an equity method investment totaling $21.6 million and $15.1 million, respectively.

Net Income Per Share

Net Income Per Share

Basic income per share is calculated using the Company's weighted-average outstanding common shares. Diluted 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.

The following table presents the calculation of both basic and diluted net income per share (in thousands, except per share amounts): 

	Three Months Ended				Six Months Ended
	June 29, 2019		June 30, 2018		June 29, 2019		June 30, 2018
Net income	$	7,207	$	10,471	$	29,727	$	30,872
Weighted-average common shares outstanding	28,079		27,615		27,970		27,802
Dilutive effect of employee stock awards	684		722		809		856
Diluted weighted-average common shares outstanding	28,763		28,337		28,779		28,658
Basic income per share	$	0.26	$	0.38	$	1.06	$	1.11
Diluted income per share	$	0.25	$	0.37	$	1.03	$	1.08

Employee stock awards representing approximately 0.2 million shares of common stock for the three months ended June 29, 2019 and June 30, 2018, and approximately 0.1 million shares of common stock for the six months ended June 29, 2019 and June 30, 2018, were excluded from the computation of diluted earnings per share as their effect would have been antidilutive.

Recent Accounting Pronouncements

Recently Adopted Accounting Standards

In June 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-07, "Compensation - Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting (Topic 718)." The amendments in ASU No. 2018-07 expand the scope of Topic 718 to include share-based payments issued to nonemployees for goods or services. The amendments in this ASU are effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods, with early adoption permitted. The Company adopted this standard effective December 30, 2018 which did not have a material impact on the Company's consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02 "Leases." This ASU and subsequently issued amendments require lessees to recognize the assets and liabilities on their balance sheet for the rights and obligations created by most leases and continue to recognize expenses on their income statements over the lease term. The standard also requires disclosures designed to give financial statement users information on the amount, timing and uncertainty of cash flows arising from leases. In July 2018, the FASB issued ASU No. 2018-11, "Leases (Topic 842): Targeted Improvements," which provides an alternative transition method that entities can elect when adopting the new standard. Under this alternative transition method, a company is permitted to use its effective date as the date of initial application without restating comparative period financial statements. The Company adopted the standard effective December 30, 2018 using the alternative transition method which resulted in the recognition of operating lease right-of-use assets and operating lease liabilities of approximately $52.8 million and $67.3 million, respectively. The Company's consolidated financial statements as of and for the three and six months ended June 29, 2019 are presented under the new standard, while the comparative quarter presented is not adjusted and continues to be reported in accordance with the historical accounting policy. See Note 4, "Leases," for the required disclosures related to the impact of adopting this standard and a discussion of the Company's updated policies related to lease accounting.

Recently Issued Accounting Standards

In August 2018, the FASB issued ASU No. 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software." The new standard aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The amendments to this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. Implementation should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently evaluating the impact of the standard on its consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurement: Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement." The amendment modifies disclosure requirements related to fair value measurement. The amendments to this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Implementation on a prospective or retrospective basis varies by specific disclosure requirement. Early adoption is permitted. The standard also allows for early adoption of any removed or modified disclosures upon issuance of this ASU while delaying adoption of the additional disclosures until their effective date. The Company does not believe this amendment will have a material impact on its consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, "Measurement of Credit Losses on Financial Instruments," as clarified in ASU No. 2019-04 and ASU No. 2019-05. The guidance amends the impairment model by requiring entities to use a forward-

looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments. This may result in the earlier recognition of allowances for losses. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of the standards on 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 recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption.

Contract liabilities	3,075		5,756

The Company invoices customers based upon contractual billing schedules, and accounts receivable are recorded when the right to consideration becomes unconditional. Contract liabilities primarily relate to prepayments received from customers in advance of product shipments. The change in the opening and closing balances of the Company’s contract assets and contract liabilities primarily results from the timing difference between the Company’s performance and the customer’s payment. During the three months ended June 29, 2019 and June 30, 2018, the Company recognized $5.3 million and $6.3 million, respectively, of the contract liability balance as revenue upon transfer of the products to customers. During the six months ended June 29, 2019 and June 30, 2018, the Company recognized $5.8 million and $6.7 million, respectively, of the contract liability balance as revenue upon transfer of the products to customers. The Company does not assess whether a prepayment received represents a significant financing component as the period between when the payment is received and the transfer of the products to the customer is generally one year or less.

[1] As of June 29, 2019, the Company’s investments had maturity dates ranging from August 2019 to March 2021.

[2] Level 2 fair value estimates are based on observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

[3] Level 3 fair value estimates are based on inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques, including option pricing and discounted cash flow models. Unobservable inputs used in the models are significant to the fair values of the assets and liabilities.
