NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1: Summary of Significant Accounting Policies

As permitted by the rules of the Securities and Exchange Commission applicable to Quarterly Reports on Form 10-Q, these notes are condensed and do not contain all disclosures required by generally accepted accounting principles (GAAP). As a result of the adoption of ASC 842 "Leases," Cognex Corporation (the "Company") has provided new disclosures related to leases in this Quarterly Report on Form 10-Q. Reference should be made to the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 for a full description of other significant accounting policies.

In the opinion of the management of the Company, the accompanying consolidated unaudited financial statements contain all adjustments, consisting of normal, recurring adjustments, and financial statement reclassifications necessary to present fairly the Company’s financial position as of June 30, 2019, and the results of its operations for the three-month and six-month periods ended June 30, 2019 and July 1, 2018, and changes in shareholders’ equity, comprehensive income, and cash flows for the periods presented.

The results disclosed in the Consolidated Statements of Operations for the three-month and six-month periods ended June 30, 2019 are not necessarily indicative of the results to be expected for the full year.

Leases

The Company accounts for leases in accordance with Accounting Standard Codification (ASC) 842, "Leases." The core principle of ASC 842 is that a lessee should recognize on the balance sheet the assets and liabilities that arise from leases.

At inception of a contract, the Company determines whether that contract is or contains a lease. The Company determines whether a contract contains a lease by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset for a period of time in exchange for consideration. The Company has control of the asset if it has the right to direct the use of the asset and obtains substantially all of the economic benefits from the use of the asset throughout the period of use.

As a practical expedient, the Company does not recognize a lease asset or lease liability for leases with a lease term of 12 months or less. In the determination of the lease term, the Company considers the existence of extension or termination options and the probability of those options being exercised.

Lease contracts may include lease components and non-lease components, such as common area maintenance and utilities for property leases. As a practical expedient, the Company accounts for the non-lease components together with the lease components as a single lease component for all of its leases.

The Company classifies a lease as a finance lease when it meets any of the following criteria at the lease commencement date: a) the lease transfers ownership of the underlying asset to the Company by the end of the lease term; b) the lease grants the Company an option to purchase the underlying asset that the Company is reasonably certain to exercise; c) the lease term is for the major part of the remaining economic life of the underlying asset (the Company considers a major part to be 75% or more of the remaining economic life of the underlying asset); d) the present value of the sum of the lease payments and any residual value guaranteed by the Company equals or exceeds substantially all of the fair value of the underlying asset (the Company considers substantially all the fair value to be 90% or more of the fair value of the underlying asset amount); or e) the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. When none of the criteria above are met, the Company classifies the lease as an operating lease.

On the lease commencement date, the Company records a lease asset and lease liability on the balance sheet. The lease asset consists of: 1) the amount of the initial lease liability; 2) any lease payments made to the lessor at or before the lease commencement date, minus any lease incentives received; and 3) any initial direct cost incurred by the Company. Initial direct costs are incremental costs of a lease that would not have been incurred if the lease had not been obtained and are capitalized as part of the lease asset.

The lease liability equals the present value of the future cash payments discounted using the Company's incremental borrowing rate. The Company’s incremental borrowing rate is the rate of interest that the Company would have to pay to borrow an amount equal to the lease payments over a similar term, which is the three-month London Interbank Offered Rate (LIBOR) plus a 2.5% credit risk spread.

9

Operating lease expense equals the total cash payments recognized on a straight-line basis over the lease term. The amortization of the lease asset is calculated as the straight-line lease expense less the accretion of the interest on the lease liability each period. The lease liability is reduced by the cash payment less the interest each period.

NOTE 2: New Pronouncements

Accounting Standards Update (ASU) 2016-13, "Financial Instruments - Measurement of Credit Losses"

ASU 2016-13 applies to all reporting entities holding financial assets that are not accounted for at fair value through net income (debt securities).  The amendments in this ASU eliminate the probable initial recognition threshold to recognize a credit loss under current U.S. GAAP and, instead, reflect an entity’s current estimate of all expected credit losses. In addition, this ASU broadens the information an entity must consider in developing the credit loss estimate, including the use of reasonable and supportable forecasted information.  The amendments in this ASU require that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down and an entity will be able to record reversals of credit losses in current period net income. For public companies, the guidance in ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods.  This ASU should be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective.  Management does not expect ASU 2016-13 to have a material impact on the Company's financial statements and disclosures.

Accounting Standards Update (ASU) 2017-08, "Receivables - Nonrefundable Fees and Other Costs - Premium Amortization on Purchased Callable Debt Securities"

ASU 2017-08 applies to all reporting entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date (that is, at a premium). The amendments in this ASU shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. Under current GAAP, premiums and discounts on callable debt securities generally are amortized to the maturity date. If that callable debt security is subsequently called, the entity records a loss equal to the unamortized premium. The amendments in this ASU more closely align the amortization period of premiums and discounts to expectations incorporated in market pricing on the underlying securities. For public companies, the amendments in ASU 2017-08 are effective for annual periods beginning after December 15, 2019 and interim reporting periods within annual years beginning after December 15, 2020. This ASU should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption, and, in the period of adoption, the entity is required to provide disclosures about the change in accounting principle. Early adoption is permitted, including adoption in an interim period. Management does not expect ASU 2017-08 to have a material impact on the Company's financial statements and disclosures.

Accounting Standards Update (ASU) 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software"

ASU 2018-15 applies to entities that are a customer in a hosting arrangement that is a service contract. The amendments in this ASU align 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. Accordingly, the amendments in this ASU require an entity in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. Further, it requires the entity to expense the capitalized implementation costs over the term of the hosting arrangement. In addition, it requires the presentation of the expenses related to the capitalized implementation costs in the same line item in the statement of income as the fees associated with the hosting element of the arrangement and the classification of the payments for the capitalized implementation costs in the statement of cash flows in the same manner as the payments made for the fees associated with the hosting element. The amendments in this ASU are effective for public entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. Management does not expect ASU 2018-15 to have a material impact on the Company's financial statements and disclosures.

NOTE 3: Fair Value Measurements

Financial Assets and Liabilities that are Measured at Fair Value on a Recurring Basis

The following table summarizes the financial assets and liabilities required to be measured at fair value on a recurring basis as of June 30, 2019 (in thousands):

	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant  Other Observable Inputs (Level 2)		Unobservable Inputs (Level 3)
Assets:
Money market instruments	$	3,099	$	—	$	—
Treasury bills	—		307,490		—
Corporate bonds	—		278,991		—
Asset-backed securities	—		145,432		—
Sovereign bonds	—		20,823		—
Agency bonds	—		13,686		—
Municipal bonds	—		6,097		—
Economic hedge forward contracts	—		20		—
Liabilities:
Economic hedge forward contracts	—		13		—
Contingent consideration liabilities	—		—		1,691

The Company’s money market instruments are reported at fair value based upon the daily market price for identical assets in active markets, and are therefore classified as Level 1.

The Company’s debt securities and forward contracts are reported at fair value based upon model-driven valuations in which all significant inputs are observable or can be derived from or corroborated by observable market data for substantially the full term of the asset or liability, and are therefore classified as Level 2. Management is responsible for estimating the fair value of these financial assets and liabilities, and in doing so, considers valuations provided by a large, third-party pricing service. For debt securities, this service maintains regular contact with market makers, brokers, dealers, and analysts to gather information on market movement, direction, trends, and other specific data. They use this information to structure yield curves for various types of debt securities and arrive at the daily valuations. The Company's forward contracts are typically traded or executed in over-the-counter markets with a high degree of pricing transparency. The market participants are generally large commercial banks.

The Company did not record an other-than-temporary impairment of these financial assets during the three-month or six-month periods ended June 30, 2019 and July 1, 2018.

The Company's contingent consideration liabilities are reported at fair value based upon probability-adjusted present values of the consideration expected to be paid using significant inputs that are not observable in the market and are therefore classified as Level 3. Key assumptions used in these estimates include probability assessments with respect to the likelihood of achieving certain revenue milestones. The fair values of these contingent consideration liabilities were calculated using discount rates consistent with the level of risk of achievement, and are remeasured each reporting period with changes in fair value recorded in "Other income (expense)" on the Consolidated Statements of Operations.

The following table summarizes the activity for the Company's liability measured at fair value using Level 3 inputs for the six-month period ended June 30, 2019 (in thousands):

Balance as of December 31, 2018	$	2,554
Fair value adjustment to GVi contingent consideration	(1,019		)
Fair value adjustment to Chiaro contingent consideration	156
Balance as of June 30, 2019	$	1,691

Non-financial Assets that are Measured at Fair Value on a Non-recurring Basis

Non-financial assets such as property, plant and equipment, goodwill, and intangible assets are required to be measured at fair value only when an impairment loss is recognized. The Company did not record an impairment charge related to these assets during the three-month or six-month periods ended June 30, 2019 and July 1, 2018.

As of June 30, 2019, the Company did not recognize any other-than-temporary impairment of these investments. In its evaluation, management considered the type of security, the credit rating of the security, the length of time the security has been in a loss position, the size of the loss position, the Company's intent and ability to hold the security to expected recovery of value, and other meaningful information. The Company does not intend to sell, and is unlikely to be required to sell, any of these available-for-sale investments before their effective maturity or market price recovery.

The Company recorded gross realized gains and gross realized losses on the sale of debt securities totaling $394,000 and $12,000, respectively, during the three-month period ended June 30, 2019 and $308,000 and $61,000, respectively, during the three-month period ended July 1, 2018. The Company recorded gross realized gains and gross realized losses on the sale of debt securities totaling $458,000 and $36,000, respectively, during the six-month period ended June 30, 2019 and $363,000 and $94,000, respectively, during the six-month period ended July 1, 2018. These gains and losses are included in "Investment income" on the Consolidated Statements of Operations. Prior to the sale of these securities, unrealized gains and losses for these debt securities, net of tax, are recorded in shareholders’ equity as accumulated other comprehensive loss.

NOTE 6:  Leases

On January 1, 2019, the Company adopted Accounting Standards Codification (ASC) 842, “Leases,” using the transition method of adoption, which allowed the Company to apply the standard on a prospective basis with a cumulative-effect adjustment to the opening balance sheet as of the adoption date. Accordingly, the Company recorded lease assets

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

of $17,522,000, current lease liabilities of $4,736,000, and non-current lease liabilities of $12,669,000 on its Consolidated Balance Sheet as of January 1, 2019.

As part of the adoption, the Company elected a practical expedient package to be applied to all of its leases upon transition, and as a result, the Company did not reassess: 1) whether any expired or existing contracts contain leases; 2) the lease classification for any expired or existing leases; and 3) the accounting for initial direct costs for any existing leases.

The Company's leases are primarily leased properties across different worldwide locations where the Company conducts its operations. All of these leases are classified as operating leases. Certain leases may contain options to extend or terminate the lease at the Company's sole discretion. There were no options to extend or terminate that were included in the determination of the lease term for the leases outstanding as of June 30, 2019. Certain leases contain leasehold improvement incentives, retirement obligations, escalating clauses, rent holidays, and variable payments tied to a consumer price index. There were no restrictions or covenants for the leases outstanding as of June 30, 2019.

The total operating lease expense for the three-month and six-month periods ended June 30, 2019 was $1,742,000 and $3,227,000, respectively. The total operating lease cash payments for the three-month and six-month periods ended June 30, 2019 was $1,669,000 and $3,070,000, respectively. The total lease expense for leases with a term of twelve months or less for which the Company elected not to recognize a lease asset or lease liability was $64,000 and $233,000 for the three-month and six-month periods ended June 30, 2019, respectively.

Future operating lease cash payments are as follows (in thousands):

Year Ended December 31,	Amount
Remainder of fiscal 2019	$	3,387
2020	5,730
2021	4,397
2022	2,890
2023	2,035
2024	842
Thereafter	311
	$	19,592

The discounted present value of the future lease cash payments resulted in a lease liability of $17,984,000 as of June 30, 2019.

The weighted-average discount rate was 4.8% for the leases outstanding as of June 30, 2019. The weighted-average remaining lease term was 3.6 years for the leases outstanding as of June 30, 2019. The Company did not have any leases that have not yet commenced but that create significant rights and obligations as of June 30, 2019.

The Company owns a building adjacent to its corporate headquarters that is partially occupied with a tenant who has a lease agreement that will expire in 2022. Rental income was $81,000 and $83,000 for the three-month period ended June 30, 2019 and July 1, 2018, respectively. Rental income was $158,000 and $159,000 for the six-month period ended June 30, 2019 and July 1, 2018, respectively.

Future minimum rental receipts under non-cancelable lease agreements are as follows (in thousands):

NOTE 8: Warranty Obligations

The Company records the estimated cost of fulfilling product warranties at the time of sale based upon historical costs to fulfill claims. Obligations may also be recorded subsequent to the time of sale whenever specific events or circumstances impacting product quality become known that would not have been taken into account using historical data. While we engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers and third-party contract manufacturers, the Company’s warranty obligation is affected by product failure rates, material usage, and service delivery costs incurred in correcting a product failure. An adverse change in any of these factors may result in the need for additional warranty provisions. Warranty obligations are included in “Accrued expenses” on the Consolidated Balance Sheets.

The changes in the warranty obligation were as follows (in thousands):

Balance as of December 31, 2018	$	4,743
Provisions for warranties issued during the period	2,533
Fulfillment of warranty obligations	(1,824		)

NOTE 9: Derivative Instruments

The Company’s foreign currency risk management strategy is principally designed to mitigate the potential financial impact of changes in the value of transactions and balances denominated in foreign currencies resulting from changes in foreign currency exchange rates. Currently, the Company enters into economic hedges to manage this risk. The economic hedges utilize foreign currency forward contracts with maturities of up to 45 days to manage the exposure to fluctuations in foreign currency exchange rates arising primarily from foreign-denominated receivables and payables. The gains and losses on these derivatives are intended to be offset by the changes in the fair value of the assets and

Costs to Fulfill a Contract

Costs to fulfill a contract are included in "Prepaid expenses and other current assets" on the Consolidated Balance Sheet and amounted to $6,852,000 and $3,514,000 as of June 30, 2019 and December 31, 2018, respectively.

Accounts Receivable, Contract Assets, and Contract Liabilities

Accounts receivable represent amounts billed and currently due from customers which are reported at their net estimated realizable value. The Company maintains reserves against its accounts receivable for potential credit losses. Credit losses recognized on accounts receivable were immaterial for the three-month and six-month periods ended June 30, 2019 and July 1, 2018, respectively. Contract assets consist of unbilled revenue which arises when revenue is recognized in advance of billing for certain application-specific customer solutions contracts. Contract liabilities consist of deferred revenue and customer deposits which arise when amounts are billed to or collected from customers in advance of revenue recognition.

The following table summarizes the deferred revenue and customer deposits activity for the six-month period ended June 30, 2019 (in thousands):

Balance as of December 31, 2018	$	9,845

Balance as of June 30, 2019	$	18,332

As a practical expedient, the Company has elected not to disclose the aggregate amount of the transaction price allocated to unsatisfied performance obligations, as our contracts have an original expected duration of less than one year.

NOTE 11: Stock-Based Compensation Expense

The Company’s share-based payments that result in compensation expense consist of stock option grants and restricted stock awards. As of June 30, 2019, the Company had 17,363,952 shares available for grant. Stock options are granted with an exercise price equal to the market value of the Company’s common stock at the grant date and generally vest over four or five years based upon continuous service and expire ten years from the grant date.

 (1) In addition to the vested options, the Company expects a portion of the unvested options to vest at some point in the future. Options expected to vest are calculated by applying an estimated forfeiture rate to the unvested options.

The fair values of stock options granted in each period presented were estimated using the following weighted-average assumptions:

	Three-months Ended				Six-months Ended
	June 30, 2019		July 1, 2018		June 30, 2019		July 1, 2018
Risk-free rate	2.7	%	2.9	%	2.7	%	2.9	%
Expected dividend yield	0.39	%	0.32	%	0.39	%	0.32	%
Expected volatility	37	%	39	%	37	%	39	%
Expected term (in years)	5.2		5.4		5.3		5.3

Risk-free rate

The risk-free rate was based upon a treasury instrument whose term was consistent with the contractual term of the option.

Expected dividend yield

Generally, the current dividend yield is calculated by annualizing the cash dividend declared by the Company’s Board of Directors and dividing that result by the closing stock price on the grant date. 

Expected volatility

The expected volatility was based upon a combination of historical volatility of the Company’s common stock over the contractual term of the option and implied volatility for traded options of the Company’s stock.

Expected term

The expected term was derived from the binomial lattice model from the impact of events that trigger exercises over time.

The Company stratifies its employee population into two groups: one consisting of senior management and another consisting of all other employees. The Company currently applies an estimated annual forfeiture rate of 9% to all unvested options for senior management and a rate of 12% for all other employees. Each year during the first quarter, the Company revises its estimated forfeiture rate. This resulted in a decrease to compensation expense of $499,000 in 2019 and in increase to compensation expense of $1,283,000 in 2018.

The weighted-average grant-date fair values of stock options granted during the three-month periods ended June 30, 2019 and July 1, 2018 were $18.68 and $21.63, respectively. The weighted-average grant-date fair values of stock options granted during the six-month periods ended June 30, 2019 and July 1, 2018 were $18.59 and $21.62, respectively.

NOTE 12: Stock Repurchase Program

In October 2018, the Company's Board of Directors authorized the repurchase of $200,000,000 of the Company's common stock. As of June 30, 2019, the Company repurchased 1,601,000 shares at a cost of $70,312,000 under this program, including 1,398,000 shares at a cost of $61,690,000 in 2019, all of which were repurchased in the three-month period ended June 30, 2019. The Company may repurchase shares under this program in future periods, up to the remaining balance of $129,688,000, depending upon a variety of factors, including, among other things, the impact of dilution from employee stock options, stock price, share availability, and cash requirements.

NOTE 13: Taxes

A reconciliation of the United States federal statutory corporate tax rate to the Company’s income tax expense, or effective tax rate, was as follows:

	Three-months Ended				Six-months Ended
	June 30, 2019		July 1, 2018		June 30, 2019		July 1, 2018
Income tax expense at U.S. federal statutory corporate tax rate	21	%	21	%	21	%	21	%
State income taxes, net of federal benefit	1	%	2	%	1	%	2	%
Foreign tax rate differential	(7	)%	(7	)%	(7	)%	(7	)%

Management has determined that earnings from its legal entity in China will be indefinitely reinvested to provide sufficient local funding for growth, and that earnings from all other jurisdictions will not be indefinitely reinvested. The Company is tax resident in numerous jurisdictions around the world and has identified its major tax jurisdictions as the United States, Ireland, and China. The statutory tax rate is 12.5% in Ireland and 25% in China, compared to the U.S. federal statutory corporate tax rate of 21%. International rights to certain of the Company's intellectual property are held by a subsidiary whose legal jurisdiction does not tax this income, resulting in a foreign effective tax rate that is lower than

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

the above mentioned statutory rates, although the reduced taxes overseas have been partially offset by changes in U.S. tax law. These differences resulted in a decrease in the effective tax rate by 7 percentage points for all periods presented.

The excess tax benefit arising from the difference between the deduction for tax purposes and the compensation cost recognized for financial reporting purposes from stock option exercises resulted in a decrease in the effective tax rate by 2 and 1 percentage points for the three-month periods ended June 30, 2019 and July 1, 2018, respectively, and a decrease in the effective tax rate by 4 and 5 percentage points for the six-month periods ended June 30, 2019 and July 1, 2018, respectively.

During the six-month period ended June 30, 2019, the Company recorded a $952,000 increase in reserves for income taxes, net of deferred tax benefit. Estimated interest and penalties included in these amounts totaled $155,000 for the six-month period ended June 30, 2019.

The Company’s reserve for income taxes, including gross interest and penalties, was $9,119,000 as of June 30, 2019, which included $8,091,000 classified as a non-current liability and $1,028,000 recorded as a reduction to non-current deferred tax assets. The amount of gross interest and penalties included in these balances was $1,019,000. If the Company’s tax positions were sustained or the statutes of limitations related to certain positions expired, these reserves would be released and income tax expense would be reduced in a future period. As a result of the expiration of certain statutes of limitations, there is a potential that a portion of these reserves could be released, which would decrease income tax expense by approximately $1,250,000 to $1,350,000 over the next twelve months.

The Company has defined its major tax jurisdictions as the United States, Ireland, and China, and within the United States, Massachusetts. Within the United States, the tax years 2015 through 2018 remain open to examination by the Internal Revenue Service and various state tax authorities. The tax years 2014 through 2018 remain open to examination by various taxing authorities in other jurisdictions in which the Company operates.

Executive Overview

Cognex Corporation is a leading worldwide provider of machine vision products that capture and analyze visual information in order to automate tasks, primarily in manufacturing processes, where vision is required. In addition to product revenue derived from the sale of machine vision products, the Company also generates revenue by providing maintenance and support, consulting, and training services to its customers; however, service revenue accounted for less than 10% of total revenue for all periods presented.

Cognex machine vision is primarily used to automate manufacturing and distribution processes in a variety of industries where the technology is widely recognized as an important component of automated production and quality assurance. Virtually every manufacturer can achieve better quality and manufacturing efficiency by using machine vision, and therefore, Cognex products are used by a broad base of customers across a variety of industries, including consumer electronics, automotive, consumer products, food and beverage, pharmaceuticals, and medical devices. Cognex products are also used to automate distribution processes in the logistics industry for applications in retail distribution and ecommerce to scan, track, and sort goods through distribution centers.

Revenue for the second quarter of 2019 totaled $199,047,000, representing a decrease of 6% from the second quarter of 2018. Strong sales in the logistics industry were offset by lower sales in the consumer electronics and automotive industries, as well as the unfavorable impact of changes in foreign currency exchange rates on revenue. Gross margin as a percentage of revenue remained consistent at 74% for each of the second quarter of 2019 and 2018. Operating expenses in the second quarter of 2019 increased by 3% over the second quarter of 2018 due principally to the impact of headcount additions to support our future growth plans. Operating income was 26% of revenue in the second quarter of 2019 compared to 30% of revenue in the second quarter of 2018; net income was 24% of revenue in the second quarter of 2019 compared to 27% of revenue in the second quarter of 2018; and net income per diluted share was $0.28 in the second quarter of 2019 compared to $0.32 in the second quarter of 2018.

Results of Operations

As foreign currency exchange rates are a factor in understanding period-to-period comparisons, we believe the presentation of results on a constant-currency basis in addition to reported results helps improve investors’ ability to understand our operating results and evaluate our performance in comparison to prior periods. We also use results on a constant-currency basis as one measure to evaluate our performance. Constant-currency information compares results between periods as if exchange rates had remained constant period-over-period. We generally refer to such amounts calculated on a constant-currency basis as excluding the impact of foreign currency exchange rate changes. Results on a constant-currency basis are not in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and should be considered in addition to, and not as a substitute for, results prepared in accordance with U.S. GAAP.

Revenue

Revenue decreased by $12,217,000, or 6%, for the three-month period and decreased by $8,300,000, or 2%, for the six-month period. Changes in foreign currency exchange rates accounted for a decrease in revenue of approximately 3 percentage points in both periods, as sales denominated in Euros and Chinese Yuan were translated to U.S. Dollars at a lower rate. Excluding the impact of changes in foreign currency exchange rates, constant-currency revenue decreased by 3% for the three-month period and increased by 1% for the six-month period. Strong sales in the logistics industry were offset by lower sales in the consumer electronics and automotive industries, as described by region below.

Sales to customers based in the Americas increased by 9% for the three-month period and 10% for the six-month period driven by higher sales in the logistics industry, partially offset by lower sales in the automotive industry.

Sales to customers based in Europe decreased by 16% for the three-month period and 6% for the six-month period, with changes in foreign currency exchange rates accounting for approximately 6 percentage points of the decrease in both periods. On a constant-currency basis, sales to customers based in Europe decreased by 10% for the three-month period and were relatively flat for the six-month period. Lower sales in the consumer electronics industry drove the decrease in both periods, which was offset by higher sales in the logistics industry for the six-month period.

Sales to customers based in Greater China decreased by 13% for the three-month period and 14% for the six-month period, with changes in foreign currency exchange rates accounting for approximately 6 percentage points of the decrease in both periods. On a constant-currency basis, sales to customers based in Greater China decreased by 7% for the three-month period and 8% for the six-month period. Sales to customers based in other regions in Asia decreased by 7% for the three-month period and 6% for the six-month period. The decline for both periods in Greater China and other Asia was due to lower sales in the consumer electronics industry.

As of the date of this report, we expect revenue for the third quarter of 2019 to decrease from both the $199 million we reported in the second quarter of 2019 and the $232 million we reported in the third quarter of 2018.

The decrease from the third quarter of 2018 is expected to come from significantly lower revenue in the consumer electronics industry, primarily related to smartphone manufacturing. Delays and reductions in capital spending from a broad base of factory automation customers, including those in the automotive industry, are also expected to contribute to the decrease from the prior year, offset by expected growth in the logistics industry.

The decrease from the second quarter of 2019 is expected to come from seasonal softness we typically experience in the third quarter outside of the consumer electronics industry. As of the date of this report, we believe this year’s sequential decline will be more pronounced than the prior year given current uncertainties around global growth and trade.

Gross Margin

Gross margin as a percentage of revenue was 74% for both the three-month and six-month periods in 2019 compared to 74% and 75% for the same quarters in 2018. The decline in the gross margin percentage for the six-month period was due primarily to the unfavorable absorption of manufacturing overhead costs, as well as the unfavorable impact of changes in foreign currency exchange rates on revenue, as the majority of our cost of revenue is based in U.S. Dollars.

As of the date of this report, we expect the gross margin percentage to be in the mid 70s range for the third quarter of 2019, slightly lower than the gross margin percentage we reported in the second quarter of 2019.

22

Operating Expenses

Research, development, and engineering (RD&E) expenses increased by $1,191,000, or 4%, for the three-month period and $357,000, or 1%, for the six-month period as detailed in the table below (in thousands).

	Three-month period			Six-month period
RD&E expenses in 2018	$	26,888		$	57,964
Personnel-related costs	1,099			2,198
Incentive compensation plans	(1,086		)	(1,344		)
Foreign currency exchange rate changes	(537		)	(1,266		)
Other	1,715			769
RD&E expenses in 2019	$	28,079		$	58,321

RD&E expenses increased due to higher personnel-related costs resulting primarily from headcount additions to support new product initiatives. These increases were partially offset by lower expenses related to incentive compensation plans resulting from lower levels of achievement on performance plans that were set at the beginning of the year. Changes in foreign currency exchange rates also resulted in a lower level of expenses, as costs denominated in foreign currencies were translated to U.S. Dollars at a lower rate.

RD&E expenses as a percentage of revenue were 14% and 16% for the three-month and six-month periods in 2019, respectively, compared to 13% and 15% for the same periods in 2018. We believe that a continued commitment to RD&E activities is essential in order to maintain or achieve product leadership with our existing products and to provide innovative new product offerings, as well as to provide engineering support for large customers. In addition, we consider our ability to accelerate time to market for new products to be critical to our revenue growth. Therefore, we expect to continue to make significant RD&E investments in the future, and we target our RD&E spending to be between 10% and 15% of revenue on an annual basis. This quarterly percentage is impacted by revenue levels and investing cycles.

Selling, General, and Administrative Expenses

Selling, general, and administrative (SG&A) expenses increased by $1,493,000, or 2%, for the three-month period and $4,607,000, or 4%, for the six-month period as detailed in the table below (in thousands).

	Three-month period			Six-month period
SG&A expenses in 2018	$	66,752		$	130,449
Personnel-related costs	6,093			13,878
Foreign currency exchange rate changes	(1,931		)	(3,616		)
Incentive compensation plans	(2,117		)	(3,097		)
ERP project costs	(1,422		)	(2,667		)
Other	870			109
SG&A expenses in 2019	$	68,245		$	135,056

SG&A expenses increased due to higher personnel-related costs resulting primarily from headcount additions, principally sales personnel. In addition to salaries and fringe benefits, these personnel-related costs included sales commissions and travel expenses related to the additional headcount. These increases were partially offset by lower expenses related to incentive compensation plans, including company bonuses and sales commissions, resulting from lower levels of achievement on performance plans that were set at the beginning of the year. Expenses were also lower due to project costs incurred in the first half of 2018 related to the Company's new Enterprise Resource Planning (ERP) system. This system was placed into service in the middle of 2018, and therefore, similar costs were not incurred in the first half of 2019. Changes in foreign currency exchange rates also resulted in a lower level of expenses, as costs denominated in foreign currencies were translated to U.S. Dollars at a lower rate.

Non-operating Income (Expense)

The Company recorded foreign currency gains of $140,000 and foreign currency losses of $108,000 for the three-month and six-month periods in 2019, respectively, compared to foreign currency losses of $195,000 and $329,000 for the same periods in 2018. Foreign currency gains and losses result primarily from the revaluation and settlement of accounts receivable, accounts payable, and intercompany balances that are reported in one currency and collected in another.

23

Investment income increased by $1,664,000, or 47%, for the three-month period and increased by $3,329,000, or 49%, for the six-month period. The increase was due to higher yields on the Company's portfolio of debt securities, and to a lesser extent additional funds available for investment.

The Company recorded other expense of $144,000 and other income of $783,000 for the three-month and six-month periods in 2019, respectively, compared to other expense of $246,000 and other income of $31,000 for the same periods in 2018. Other income (expense) includes fair value adjustments of contingent consideration liabilities arising from business acquisitions.

Income Tax Expense

The Company’s effective tax rate was 14% and 12% of pre-tax income for the three-month and six-month periods in 2019, respectively, compared to 16% and 11% for the same periods in 2018.

The effective tax rate included a decrease in tax expense of $1,248,000 and $3,978,000 for the three-month and six-month periods in 2019, respectively, and $654,000 and $5,589,000 for the same periods in 2018 primarily from the excess tax benefit arising from the difference between the deduction for tax purposes and the compensation cost recognized for financial reporting purposes from stock option exercises. The Company cannot predict the level of stock option exercises by employees in future periods.

Excluding the impact of these discrete tax events, the Company’s effective tax rate was 17% of pre-tax income for both three-month periods and 16% for both six-month periods.

The Company is tax resident in numerous jurisdictions around the world and has identified its major tax jurisdictions as the United States, Ireland, and China. The statutory tax rate is 12.5% in Ireland and 25% in China, compared to the U.S. federal statutory corporate tax rate of 21%. International rights to certain of the Company’s intellectual property are held by a subsidiary whose legal jurisdiction does not tax this income, resulting in a foreign effective tax rate lower than the above mentioned statutory rates, although the reduced taxes overseas have been partially offset by changes in U.S. tax law. The European Union has initiated a series of tax reform legislation over the past few years that may have an impact on the Company’s tax provision and related filings in future periods. The Company is reviewing the legislation but has not determined the impact to future periods or whether changes to its tax structure will be made.

Liquidity and Capital Resources

The Company has historically been able to generate positive cash flow from operations, which has funded its operating activities and other cash requirements and has resulted in an accumulated cash and investment balance of $861,623,000 as of June 30, 2019. The Company has established guidelines relative to credit ratings, diversification, and maturities of its investments that maintain liquidity.

The Company’s cash requirements during the six months ended June 30, 2019 were primarily met with positive cash flows from operations. Cash requirements consisted of operating activities, the repurchase of common stock, the payment of dividends, and capital expenditures. Operating cash inflows included a reduction in accounts receivable from the collection of a significant amount due from a material customer in the consumer electronics industry, as well as a reduction in inventory levels. Operating cash outflows included the payment of company bonuses that were earned and accrued in 2018.

Capital expenditures during the six months ended June 30, 2019 totaled $8,969,000 and consisted of computer hardware and software, manufacturing test equipment related to new product introductions, and improvements made to the Company's headquarters building in Natick, Massachusetts and various leased facilities.

In October 2018, the Company's Board of Directors authorized the repurchase of $200,000,000 of the Company's common stock. As of June 30, 2019, the Company repurchased 1,601,000 shares at a cost of $70,312,000 under this program, including 1,398,000 shares at a cost of $61,690,000 during the six-months ended June 30, 2019. The Company may repurchase shares under this program in future periods, up to the remaining balance of $129,688,000, depending on a variety of factors, including, among other things, the impact of dilution from employee stock options, stock price, share availability, and cash requirements.

The Company’s Board of Directors declared and paid a cash dividend of $0.05 per share in both the first and second quarters of 2019, amounting to $17,146,000. Future dividends will be declared at the discretion of the Company’s Board of Directors and will depend upon such factors as the Board deems relevant including, among other things, the Company’s ability to generate positive cash flows from operations.

The Company believes that its existing cash and investment balances, together with cash flow from operations, will be sufficient to meet its operating, investing, and financing activities for the next twelve months. As of June 30, 2019, the Company had $861,623,000 in cash and investments. In addition, the Company has no long-term debt and does

24

not anticipate needing debt financing in the near future. We believe that our strong cash position has put us in a relatively good position with respect to our longer-term liquidity needs.

EX-10.1

Exhibit 10.1 PERSONAL AND CONFIDENTIAL John J. Curran [Address] Re: Resignation Agreement Dear John: This letter confirms your upcoming separation from employment with Cognex Corporation (the “Company”). This letter also proposes an agreement between you and the Company. Entitlements and Obligations Your employment with the Company will end effective May 3, 2019 following the filing of the Company’s Form 10-Q with the Securities and Exchange Commission determined in consultation with you (the “Employment Termination Date”). Regardless of whether you enter into an agreement with the Company, the Company will: • pay you salary accrued to you through the date of termination of your employment; • pay you for all accrued but unused Paid Time Off due to you through the date of termination of your employment; • provide you with the right to continue group health plan coverage after the termination of your employment under the law known as “COBRA,” which will be described in a separate written notice; and • reimburse you for any outstanding, reasonable business expenses that you have incurred on the Company’s behalf through the termination of your employment, after the Company’s timely receipt of appropriate documentation pursuant to the Company’s business expense reimbursement policy. In addition, you have certain equity agreements with the Company, pursuant to the Company’s 2001 General Stock Option Plan, consisting of the following: • Stock Option Agreement (Non-Qualified), Grant # NH001481, with a grant date of November 2, 2016; Cognex Corporation One Vision Drive Natick, MA 01760-2059 (508) 650-3000 fax (508) 650-3333 www.cognex.com

• Stock Option Agreement (Non-Qualified), Grant # NH001482, with a grant date of November 2, 2016; and • Stock Option Agreement (Non-Qualified), Grant # NH001483, with a grant date of November 2, 2016. You also have certain equity agreements with the Company, pursuant to the Company’s 2007 Stock Option and Incentive Plan, consisting of the following: • Stock Option Agreement (Non-Qualified), Grant # NH001487, with a grant date of February 21, 2017; • Stock Option Agreement (Non-Qualified), Grant # NH001488, with a grant date of February 21, 2017; • Stock Option Agreement (Non-Qualified), Grant # NH001489, with a grant date of February 21, 2017; • Stock Option Agreement (Non-Qualified), Grant # AR011525, with a grant date of February 20, 2018; and • Stock Option Agreement (Non-Qualified), Grant # AR012020, with a grant date of February 19, 2019. The foregoing Stock Option Agreements are together referred to as the “Award Agreements.” You will be entitled to your rights under and subject to the terms of the Award Agreements regardless of whether you enter this Agreement, though the terms of or rights under the Award Agreements may be enhanced pursuant to the terms of this Agreement. Also, regardless of whether you agree to the Agreement, you will remain subject to the terms of the Employee Invention, Non-Disclosure and Non-Competition Agreement (the “Restrictive Covenants Agreement”) that you entered into with the Company on September 30, 2016, and reaffirmed in each of the Award Agreements. Agreement The remainder of this letter proposes an agreement (the “Agreement”) between you and the Company. The purpose of this Agreement is to establish an amicable arrangement for ending your employment relationship, including releasing the Company and related persons or entities from any claims and permitting you to receive separation pay and related benefits. You acknowledge that you are entering into this Agreement knowingly and voluntarily. It is customary in employment separation agreements for the departing employee to release the employer from any possible claims, even if the employer believes, as is the case here, that no such claims exist. By proposing and entering into this Agreement, the Company is not admitting in any way that it violated any legal obligation that it owed to you. Cognex Corporation One Vision Drive Natick, MA 01760-2059 (508) 650-3000 fax (508) 650-3333 www.cognex.com

With those understandings, you and the Company agree as follows: Resignation from Employment This confirms that you have resigned from your employment with the Company as Senior Vice President and Chief Financial Officer of the Company, to be effective on the Employment Termination Date (the “Resignation Date”). You further confirm that you also resign from any and all other positions that you hold with any affiliates of the Company as an officer, director or otherwise effective on the Resignation Date. You acknowledge that as of the Company’s most recent payroll payment of salary to you, you were fully paid for all salary then due and payable to you based on your employment through the payroll period applicable to such payroll date. You acknowledge that as of the date of this letter, your accrued but unused vacation time totaled [___] days. If you apply to the Massachusetts Department of Unemployment Assistance for unemployment compensation benefits under state law, the Company shall not dispute your eligibility for such benefits. This shall not affect the Company’s obligation to respond truthfully to governmental agency requests for information related to unemployment compensation eligibility. Severance Benefits Provided that you use reasonable efforts to perform your responsibilities until the Resignation Date, the Company shall provide you with the pay, benefits and other terms set forth in this Section 2 below. Severance Pay. The Company shall pay you severance pay (“Severance Pay”) consisting of salary continuation at your final base salary rate of $311,000 per year effective for the period from the date immediately following the Resignation Date to and including twelve (12) weeks following the Resignation Date (the “Severance Pay Period”). The Company shall pay you Severance Pay on its regular payroll dates; provided that the Company shall not be obligated to pay you severance pay before this Agreement becomes effective. If the Company does not make one or more payments of Severance Pay on a regular payroll date because this Agreement has not yet become effective, the Company shall make all such delayed payments by the first payroll date when it is practicable to do so after the Agreement becomes effective. Accelerated Vesting. On the Resignation Date, stock options to purchase a total of 50,000 shares of Company common stock that are scheduled to vest in accordance with their terms on November 2, 2019 but will continue to be unvested on the Resignation Date (such that they would otherwise be forfeited in the absence of this Agreement) shall vest (the “Accelerated Vesting”). The stock options subject to the Accelerated Vesting include: (i) 12,500 shares underlying options granted to you on November 2, 2016 through Grant # NH001481; (ii) 12,500 shares underlying options granted to you on November 2, 2016 through Grant # NH001482; (iii) 12,500 shares underlying options granted to you on February 21, 2017 through Grant # NH001487; and (iv) 12,500 shares underlying options granted to you on February 21, 2017 through Grant # NH001488. Any termination or forfeiture of such stock options that otherwise would have occurred as a result of the termination of your employment shall be delayed and such termination or forfeiture shall only occur if the Agreement does not become effective. In all other respects, all equity awards granted by the Company shall be subject to the terms of the Award Agreements including, without limitation, the time limits on exercise and, for the avoidance of doubt, except as Cognex Corporation One Vision Drive Natick, MA 01760-2059 (508) 650-3000 fax (508) 650-3333 www.cognex.com

specifically provided above, all equity awards granted by the Company that have not vested prior to the Resignation Date shall be automatically forfeited on the Resignation Date. Supplemental Payments. The Company shall pay the employer portion (the “Supplemental Payments”), which you may but are not required to use to defray the cost of group health plan coverage through COBRA or otherwise. The Company shall make the Supplemental Payments effective for the period from the day immediately following the Resignation Date until the earlier of the eighteen (18)-month anniversary of the Resignation Date or the date when you commence other employment. You agree to notify the Company promptly if you anticipate commencing other employment before the 18-month anniversary of the Resignation Date, including the date of such anticipated commencement of other employment. You also agree to respond promptly and fully to any reasonable requests for information by the Company concerning your employment status and anticipated employment status during such 18-month period. The Company shall commence paying the Supplemental Payments when it commences payment of Severance Pay (with any catch-up payment consistent with a catch-up payment of Severance Pay pursuant to the last sentence of Section 2(a)). Outplacement Benefits. The Company shall pay up to $5,000 with our outplacement service provider for the purpose of providing outplacement services to you; provided that you begin utilizing such services no later than three (3) months after the Effective Date. Tax Treatment. The Company shall make deductions, withholdings and tax reports with respect to payments and benefits under this Agreement that it reasonably determines to be required. Payments under this Agreement shall be in amounts net of any such deductions or withholdings. Nothing in this Agreement shall be construed to require the Company to make any payments to compensate you for any adverse tax effect associated with any payments or benefits or for any deduction or withholding from any payment or benefit. Stock Options All stock options that you hold to purchase shares of the Company’s common stock pursuant to the Award Agreements or any predecessor plan that will not have vested as of your Resignation Date shall lapse on that date and shall not be exercisable, with exception of those options explicitly set forth in Section 2(b) of this Agreement as subject to Accelerated Vesting. You acknowledge that the following summarizes all vested options that have not been exercised as of the date of this letter and that shall remain exercisable by you in accordance with the terms of the applicable Award Agreements as of the Resignation Date: Grant Date Grant Number Vested, Unexercised Shares Exercise Price November 2, 2016 NH001481 12,500 $24.86 November 2, 2016 NH001482 12,500 $24.86 February 21, 2017 NH001487 12,500 $38.39 Cognex Corporation One Vision Drive Natick, MA 01760-2059 (508) 650-3000 fax (508) 650-3333 www.cognex.com

February 21, 2017 NH001488 12,500 $38.39 February 20, 2018 AR011525 10,000 $56.44 The exercise of any such stock options shall be subject to the terms of the Award Agreements, including, without limitation, the time limits on exercise. This section is not intended to modify in any respect the rights to which you would otherwise be entitled if you were not to agree to this Agreement or the terms governing stock options. The above summary is set forth solely to confirm certain information concerning stock options. Continuing Obligations You acknowledge that your obligations under the Restrictive Covenants Agreement shall continue in effect, including, without limitation, your obligations to maintain the confidentiality of Confidential Information as defined in the Restrictive Covenants Agreement, to return documents and other property of the Company and to refrain from certain competition and solicitation activities for a period of eighteen (18) months after the Resignation Date. A copy of the Restrictive Covenants Agreement is enclosed as Exhibit A.

• for damages or other remedies of any sort, including, without limitation, compensatory damages, punitive damages, injunctive relief and attorney’s fees; provided, however, that this release shall not affect your vested rights under the Company’s Section 401(k) plan, the Award Agreements (as modified pursuant to Section 2(b) of this Agreement), rights as a stockholder of the Company, rights to be covered under applicable indemnification agreements and policies and under applicable directors and officers liability insurance for acts or omissions while serving as an executive of the Company, and your rights under this Agreement.

As a material inducement to the Company to enter into this Agreement, you represent that you have not assigned any Claim to any third party. Transitional Services You agree to provide up to ten (10) hours of transitional services to the Company during the Severance Pay Period at any reasonable times requested by the Company; provided that the Company shall not require you to provide any such services at any times that would unreasonably interfere with your search for employment or with any subsequent employment. Future Cooperation You agree to cooperate reasonably with the Company and all of its affiliates (including its and their outside counsel) in connection with (i) the contemplation, prosecution and defense of all phases of existing, past and future litigation about which the Company believes you may have knowledge or information; and (ii) responding to requests for information from regulatory agencies or other governmental authorities (together “Cooperation Services”). You further agree to make yourself available to provide Cooperation Services at mutually convenient times during and outside of regular business hours as reasonably deemed necessary by the Company’s counsel.

Cooperation Services include, without limitation, appearing without the necessity of a subpoena to testify truthfully in any legal proceedings in which the Company or an affiliate calls you as a witness. The Company shall reimburse you for any reasonable travel expenses that you incur due to your performance of Cooperation Services, after receipt of appropriate documentation consistent with the Company’s business expense reimbursement policy. In addition, for all time that you reasonably expend in providing Cooperation Services after the end of the Severance Pay Period, the Company shall compensate you at the rate of $150 per hour; provided that your right to such compensation shall not apply to time spent in activities that could have been compelled pursuant to a subpoena, including testimony and related attendance at depositions, hearings or trials.

Non-Disparagement You agree not to make any disparaging statements concerning the Company or any of its affiliates, products, services, or current or former officers, directors, shareholders, employees or agents. Protected Disclosures and Other Protected Actions Nothing contained in this Agreement limits your ability to file a charge or complaint with any federal, state or local governmental agency or commission (a “Government Agency”). In addition, nothing contained in this Agreement limits your ability to communicate with any Government Agency or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including your ability to provide documents or other information, without notice to the Company, nor does anything contained in this Agreement apply to truthful testimony in litigation. If you file any charge or complaint with any Government Agency and if the Government Agency pursues any claim on your behalf, or if any other third party pursues any claim on your behalf, you waive any right to monetary or other individualized relief (either individually or as part of any collective or class action); provided that nothing in this Agreement limits any right you may have to receive a whistleblower award or bounty for information provided to the Securities and Exchange Commission. In addition, for the avoidance of doubt, pursuant to the federal Defend Trade Secrets Act of 2016, you shall not be held criminally or civilly liable under any federal or state trade secret law or under this Agreement, the Restrictive Covenants Agreement, or the Award Agreements for the disclosure of a trade secret that (a) is made (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (b) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Other Provisions Termination of Payments. If you breach any of your obligations under this Agreement, in addition to any other legal or equitable remedies it may have for such breach, the Company shall have the right to terminate its payments to you or for your benefit under this Agreement. The termination of such payments in the event of your breach will not affect your continuing obligations under this Agreement. Absence of Reliance. In signing this Agreement, you are not relying upon any promises or representations made by anyone at or on behalf of the Company. Enforceability. If any portion or provision of this Agreement (including, without limitation, any portion or provision of any section of this Agreement) shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable, shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law. Cognex Corporation One Vision Drive Natick, MA 01760-2059 (508) 650-3000 fax (508) 650-3333 www.cognex.com

Waiver. No waiver of any provision of this Agreement shall be effective unless made in writing and signed by the waiving party. The failure of a party to require the performance of any term or obligation of this Agreement, or the waiver by a party of any breach of this Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach. Jurisdiction. You and the Company hereby agree that the Superior Court of the Commonwealth of Massachusetts and the United States District Court for the District of Massachusetts shall have the exclusive jurisdiction to consider any matters related to this Agreement, including, without limitation, any claim of a violation of this Agreement. With respect to any such court action, you submit to the jurisdiction of such courts and you acknowledge that venue in such courts is proper. Relief. You agree that it would be difficult to measure any harm caused to the Company that might result from any breach by you of your promises set forth in Sections 4 and 6-9 (the “Specified Sections”). You further agree that money damages would be an inadequate remedy for any breach of any of the Specified Sections. Accordingly, you agree that if you breach, or propose to breach, any portion of your obligations under any of the Specified Sections, the Company shall be entitled, in addition to all other remedies it may have, to an injunction or other appropriate equitable relief to restrain any such breach, without showing or proving any actual damage to the Company and without the necessity of posting a bond. If the Company prevails in any action to enforce any of the Specified Sections, then you also shall be liable to the Company for reasonable attorney’s fees and costs incurred by the Company in enforcing any of the Specified Sections. Governing Law; Interpretation. This Agreement shall be interpreted and enforced under the laws of the Commonwealth of Massachusetts, without regard to conflict of law principles. In the event of any dispute, this Agreement is intended by the parties to be construed as a whole, to be interpreted in accordance with its fair meaning, and not to be construed strictly for or against either you or the Company or the “drafter” of all or any portion of this Agreement. Entire Agreement. This Agreement constitutes the entire agreement between you and the Company. This Agreement supersedes any previous agreements or understandings between you and the Company, except the Restrictive Covenants Agreement, the Award Agreements, and any other obligations specifically preserved in this Agreement. Time for Consideration; Effective Date.

Exhibit 10.2 Grant # OT002556 LAURA MACDONALD COGNEX CORPORATION STOCK OPTION AGREEMENT (NON-QUALIFIED) UNDER 2007 STOCK OPTION AND INCENTIVE PLAN As Amended and Restated AGREEMENT entered into as of 05/01/2019, by and between COGNEX CORPORATION, a Massachusetts corporation (the "Company") and the undersigned employee of the Company or one of its subsidiaries (the "Optionee").

The Company desires to afford the Optionee an opportunity to purchase shares of its common stock ($0.002 par value) ("Shares") to carry out the purposes of the Cognex Corporation 2007 Stock Option and Incentive Plan, As Amended and Restated (the "Plan"). 2. Section 2(d) of the Plan provides that each option is to be evidenced by an option agreement, setting forth the terms and conditions of the option. ACCORDINGLY, in consideration of the premises and of the mutual covenants and agreements contained herein, the Company and the Optionee hereby agree as follows: 1. Grant of Option The Company hereby grants to the Optionee a non-qualified stock option (the "Option") to purchase all or any part of an aggregate of 10000 Shares on the terms and conditions hereinafter set forth, and the terms and conditions set forth in the Plan. 2.

Time and Manner of Exercise of Option 3.1 The Option shall not be exercisable prior to 05/01/2022. Thereafter, the Option shall only be exercisable, in the amounts and on or after the vesting dates as follows: Shares Becoming Available On or After for Exercise 05/01/2022 10000

STOCK OPTION AGREEMENT (NON-QUALIFIED) PAGE 2 Notwithstanding the foregoing, the Option shall not be exercisable until such time that the Optionee and the Company have duly executed all of the agreements required at the time of grant of the Option by the Company for 1) full-time employment by the Company, if the Optionee is an employee of the Company, including, but not limited to, the Company's Employee, Invention, Non-Disclosure and Non- Competition Agreement, or 2) consultancy by the Company, if the optionee is a consultant to the Company, including, but not limited to, the Company's Consultant Agreement, or 3) directorship of the Company, if the Optionee is a director of the Company, including, but not limited to, the Company's Confidentiality and Non-Competition Agreement. 3.2 To the extent that the right to exercise the Option has accrued and is in effect, the Option may be exercised in full at one time or in part from time to time, by giving written notice, signed by the person or persons exercising the Option, to the Company, stating the number of Shares with respect to which the Option is being exercised, accompanied by payment in full of the Purchase Price for such Shares, which payment may, at the Optionee's request and in the Company's sole discretion, be in whole or in part in shares of the common stock of the Company already owned by the person or persons exercising the Option, valued at fair market value. If such stock is traded on the NASDAQ Global Select Market System, the price shall be the last reported sale price of the stock reported by NASDAQ on such date or if no stock is traded on such date the next preceding date on which stock was traded. The Option may also be exercised by means of a broker-assisted cashless exercise method contemplated by Section 7(a) of the Plan. 3.3 The Company shall at all times during the term of the Option reserve and keep available such number of shares of its common stock as will be sufficient to satisfy the requirements of the Option, shall pay all original issue and transfer taxes with respect to the issue and transfer of Shares pursuant hereto, and all other fees and expenses necessarily incurred by the Company in connection therewith.

In the case of disability, the Option may be exercised, to the extent then exercisable under Section 3.1, at any time within twelve (12) months after the date of termination of his or her such affiliation with the Company, but in any event prior to the expiration of ten (10) years from the date hereof. 4.3 In the event of the death of the Optionee, the Option may be exercised, to the extent the Optionee was entitled to do so on the date of his or her death under the provisions of Section 3.1 by the estate of the Optionee or by any person or persons who acquire the right to exercise the Option by bequest or inheritance or otherwise by reason of the death of the Optionee. In such circumstances, the Option may be exercised at any time within twelve (12) months after the date of death of the Optionee, but in any event prior to the expiration of ten (10) years from the date hereof. 5.

Severability Each provision of this Agreement shall be treated as a separate and independent clause, and the unenforceability of any one clause shall in no way impair the enforceability of any of the other clauses herein. In the event that any provision hereof or any obligation or grant, or rights by the undersigned hereunder is found invalid or unenforceable pursuant to judicial decree or decision, any such provision, obligation, or grant of right shall be deemed and construed to extend only to the maximum permitted by law, and the remainder of this Agreement shall remain valid and enforceable according to its terms. 7.

STOCK OPTION AGREEMENT (NON-QUALIFIED) PAGE 4 8. No Special Rights Nothing contained in the Plan or in this Agreement shall be construed or deemed by any person under any circumstances to bind the Company to continue the affiliation of the Optionee as either an employee or consultant or director, with the Company for the period within which this Option may be exercised. If Optionee is an employee of the Company, he/she acknowledges the he/she is an employee “at will” and that Company provides no guarantee or assurance of the Optionee's employment with Company prior to or after the vesting dates contained in Section 3 above. 9. Non-Competition The Optionee reaffirms his/her promise to be bound by the non-competition provision as stated in the Employee Invention, Non-Disclosure and Non-Competition Agreement entered into between the Optionee and the Company (the “Employment Agreement”). The Optionee agrees that the granting of this Option and any pre-tax gains realized by the Optionee pursuant to the exercise of this Option (along with other good and valuable consideration including, but not limited to employment by the Company, salary and other Company-provided benefits) are additional and sufficient consideration for the Optionee's performance of his/her non-competition obligations as stated in the Optionee's Employment Agreement. Optionee agrees that if he or she breaches the non-competition obligations of Optionee's Employment Agreement then he or she shall pay damages to the Company, including, but not limited to an amount equal to the sum of: (a) the total of all pre-tax gains realized by Optionee as a result of the exercise of any portion of the Option and (b) the total of all pre-tax gains realized by Optionee as a result of the sale of any shares acquired by him/her through the exercise of any portion of the Option. IN WITNESS WHEREOF, the Company has caused this Agreement to be executed and its corporate seal to be hereto affixed by Robert Willett, its CEO, and President thereunto duly authorized, and the Optionee has hereunto set his or her hand and seal, all as of the day and year first above written.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

As permitted by the rules of the Securities and Exchange Commission applicable to Quarterly Reports on Form 10-Q, these notes are condensed and do not contain all disclosures required by generally accepted accounting principles (GAAP). As a result of the adoption of ASC 842 "Leases," Cognex Corporation (the "Company") has provided new disclosures related to leases in this Quarterly Report on Form 10-Q. Reference should be made to the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 for a full description of other significant accounting policies.

In the opinion of the management of the Company, the accompanying consolidated unaudited financial statements contain all adjustments, consisting of normal, recurring adjustments, and financial statement reclassifications necessary to present fairly the Company’s financial position as of June 30, 2019, and the results of its operations for the three-month and six-month periods ended June 30, 2019 and July 1, 2018, and changes in shareholders’ equity, comprehensive income, and cash flows for the periods presented.

The results disclosed in the Consolidated Statements of Operations for the three-month and six-month periods ended June 30, 2019 are not necessarily indicative of the results to be expected for the full year.

Leases

The Company accounts for leases in accordance with Accounting Standard Codification (ASC) 842, "Leases." The core principle of ASC 842 is that a lessee should recognize on the balance sheet the assets and liabilities that arise from leases.

At inception of a contract, the Company determines whether that contract is or contains a lease. The Company determines whether a contract contains a lease by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset for a period of time in exchange for consideration. The Company has control of the asset if it has the right to direct the use of the asset and obtains substantially all of the economic benefits from the use of the asset throughout the period of use.

As a practical expedient, the Company does not recognize a lease asset or lease liability for leases with a lease term of 12 months or less. In the determination of the lease term, the Company considers the existence of extension or termination options and the probability of those options being exercised.

Lease contracts may include lease components and non-lease components, such as common area maintenance and utilities for property leases. As a practical expedient, the Company accounts for the non-lease components together with the lease components as a single lease component for all of its leases.

The Company classifies a lease as a finance lease when it meets any of the following criteria at the lease commencement date: a) the lease transfers ownership of the underlying asset to the Company by the end of the lease term; b) the lease grants the Company an option to purchase the underlying asset that the Company is reasonably certain to exercise; c) the lease term is for the major part of the remaining economic life of the underlying asset (the Company considers a major part to be 75% or more of the remaining economic life of the underlying asset); d) the present value of the sum of the lease payments and any residual value guaranteed by the Company equals or exceeds substantially all of the fair value of the underlying asset (the Company considers substantially all the fair value to be 90% or more of the fair value of the underlying asset amount); or e) the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. When none of the criteria above are met, the Company classifies the lease as an operating lease.

On the lease commencement date, the Company records a lease asset and lease liability on the balance sheet. The lease asset consists of: 1) the amount of the initial lease liability; 2) any lease payments made to the lessor at or before the lease commencement date, minus any lease incentives received; and 3) any initial direct cost incurred by the Company. Initial direct costs are incremental costs of a lease that would not have been incurred if the lease had not been obtained and are capitalized as part of the lease asset.

The lease liability equals the present value of the future cash payments discounted using the Company's incremental borrowing rate. The Company’s incremental borrowing rate is the rate of interest that the Company would have to pay to borrow an amount equal to the lease payments over a similar term, which is the three-month London Interbank Offered Rate (LIBOR) plus a 2.5% credit risk spread.

Operating lease expense equals the total cash payments recognized on a straight-line basis over the lease term. The amortization of the lease asset is calculated as the straight-line lease expense less the accretion of the interest on the lease liability each period. The lease liability is reduced by the cash payment less the interest each period.

New Pronouncements

Accounting Standards Update (ASU) 2016-13, "Financial Instruments - Measurement of Credit Losses"

ASU 2016-13 applies to all reporting entities holding financial assets that are not accounted for at fair value through net income (debt securities).  The amendments in this ASU eliminate the probable initial recognition threshold to recognize a credit loss under current U.S. GAAP and, instead, reflect an entity’s current estimate of all expected credit losses. In addition, this ASU broadens the information an entity must consider in developing the credit loss estimate, including the use of reasonable and supportable forecasted information.  The amendments in this ASU require that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down and an entity will be able to record reversals of credit losses in current period net income. For public companies, the guidance in ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods.  This ASU should be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective.  Management does not expect ASU 2016-13 to have a material impact on the Company's financial statements and disclosures.

Accounting Standards Update (ASU) 2017-08, "Receivables - Nonrefundable Fees and Other Costs - Premium Amortization on Purchased Callable Debt Securities"

ASU 2017-08 applies to all reporting entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date (that is, at a premium). The amendments in this ASU shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. Under current GAAP, premiums and discounts on callable debt securities generally are amortized to the maturity date. If that callable debt security is subsequently called, the entity records a loss equal to the unamortized premium. The amendments in this ASU more closely align the amortization period of premiums and discounts to expectations incorporated in market pricing on the underlying securities. For public companies, the amendments in ASU 2017-08 are effective for annual periods beginning after December 15, 2019 and interim reporting periods within annual years beginning after December 15, 2020. This ASU should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption, and, in the period of adoption, the entity is required to provide disclosures about the change in accounting principle. Early adoption is permitted, including adoption in an interim period. Management does not expect ASU 2017-08 to have a material impact on the Company's financial statements and disclosures.

Accounting Standards Update (ASU) 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software"

ASU 2018-15 applies to entities that are a customer in a hosting arrangement that is a service contract. The amendments in this ASU align 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. Accordingly, the amendments in this ASU require an entity in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. Further, it requires the entity to expense the capitalized implementation costs over the term of the hosting arrangement. In addition, it requires the presentation of the expenses related to the capitalized implementation costs in the same line item in the statement of income as the fees associated with the hosting element of the arrangement and the classification of the payments for the capitalized implementation costs in the statement of cash flows in the same manner as the payments made for the fees associated with the hosting element. The amendments in this ASU are effective for public entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. Management does not expect ASU 2018-15 to have a material impact on the Company's financial statements and disclosures.

Fair Value Measurements

Financial Assets and Liabilities that are Measured at Fair Value on a Recurring Basis

The following table summarizes the financial assets and liabilities required to be measured at fair value on a recurring basis as of June 30, 2019 (in thousands):

	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant  Other Observable Inputs (Level 2)		Unobservable Inputs (Level 3)
Assets:
Money market instruments	$	3,099	$	—	$	—
Treasury bills	—		307,490		—
Corporate bonds	—		278,991		—
Asset-backed securities	—		145,432		—
Sovereign bonds	—		20,823		—
Agency bonds	—		13,686		—
Municipal bonds	—		6,097		—
Economic hedge forward contracts	—		20		—
Liabilities:
Economic hedge forward contracts	—		13		—
Contingent consideration liabilities	—		—		1,691

The Company’s money market instruments are reported at fair value based upon the daily market price for identical assets in active markets, and are therefore classified as Level 1.

The Company’s debt securities and forward contracts are reported at fair value based upon model-driven valuations in which all significant inputs are observable or can be derived from or corroborated by observable market data for substantially the full term of the asset or liability, and are therefore classified as Level 2. Management is responsible for estimating the fair value of these financial assets and liabilities, and in doing so, considers valuations provided by a large, third-party pricing service. For debt securities, this service maintains regular contact with market makers, brokers, dealers, and analysts to gather information on market movement, direction, trends, and other specific data. They use this information to structure yield curves for various types of debt securities and arrive at the daily valuations. The Company's forward contracts are typically traded or executed in over-the-counter markets with a high degree of pricing transparency. The market participants are generally large commercial banks.

The Company did not record an other-than-temporary impairment of these financial assets during the three-month or six-month periods ended June 30, 2019 and July 1, 2018.

The Company's contingent consideration liabilities are reported at fair value based upon probability-adjusted present values of the consideration expected to be paid using significant inputs that are not observable in the market and are therefore classified as Level 3. Key assumptions used in these estimates include probability assessments with respect to the likelihood of achieving certain revenue milestones. The fair values of these contingent consideration liabilities were calculated using discount rates consistent with the level of risk of achievement, and are remeasured each reporting period with changes in fair value recorded in "Other income (expense)" on the Consolidated Statements of Operations.

The following table summarizes the activity for the Company's liability measured at fair value using Level 3 inputs for the six-month period ended June 30, 2019 (in thousands):

Balance as of December 31, 2018	$	2,554
Fair value adjustment to GVi contingent consideration	(1,019		)
Fair value adjustment to Chiaro contingent consideration	156
Balance as of June 30, 2019	$	1,691

Non-financial Assets that are Measured at Fair Value on a Non-recurring Basis

Non-financial assets such as property, plant and equipment, goodwill, and intangible assets are required to be measured at fair value only when an impairment loss is recognized. The Company did not record an impairment charge related to these assets during the three-month or six-month periods ended June 30, 2019 and July 1, 2018.

As of June 30, 2019, the Company did not recognize any other-than-temporary impairment of these investments. In its evaluation, management considered the type of security, the credit rating of the security, the length of time the security has been in a loss position, the size of the loss position, the Company's intent and ability to hold the security to expected recovery of value, and other meaningful information. The Company does not intend to sell, and is unlikely to be required to sell, any of these available-for-sale investments before their effective maturity or market price recovery.

The Company recorded gross realized gains and gross realized losses on the sale of debt securities totaling $394,000 and $12,000, respectively, during the three-month period ended June 30, 2019 and $308,000 and $61,000, respectively, during the three-month period ended July 1, 2018. The Company recorded gross realized gains and gross realized losses on the sale of debt securities totaling $458,000 and $36,000, respectively, during the six-month period ended June 30, 2019 and $363,000 and $94,000, respectively, during the six-month period ended July 1, 2018. These gains and losses are included in "Investment income" on the Consolidated Statements of Operations. Prior to the sale of these securities, unrealized gains and losses for these debt securities, net of tax, are recorded in shareholders’ equity as accumulated other comprehensive loss.

Leases [Abstract]

Leases

Leases

On January 1, 2019, the Company adopted Accounting Standards Codification (ASC) 842, “Leases,” using the transition method of adoption, which allowed the Company to apply the standard on a prospective basis with a cumulative-effect adjustment to the opening balance sheet as of the adoption date. Accordingly, the Company recorded lease assets

of $17,522,000, current lease liabilities of $4,736,000, and non-current lease liabilities of $12,669,000 on its Consolidated Balance Sheet as of January 1, 2019.

As part of the adoption, the Company elected a practical expedient package to be applied to all of its leases upon transition, and as a result, the Company did not reassess: 1) whether any expired or existing contracts contain leases; 2) the lease classification for any expired or existing leases; and 3) the accounting for initial direct costs for any existing leases.

The Company's leases are primarily leased properties across different worldwide locations where the Company conducts its operations. All of these leases are classified as operating leases. Certain leases may contain options to extend or terminate the lease at the Company's sole discretion. There were no options to extend or terminate that were included in the determination of the lease term for the leases outstanding as of June 30, 2019. Certain leases contain leasehold improvement incentives, retirement obligations, escalating clauses, rent holidays, and variable payments tied to a consumer price index. There were no restrictions or covenants for the leases outstanding as of June 30, 2019.

The total operating lease expense for the three-month and six-month periods ended June 30, 2019 was $1,742,000 and $3,227,000, respectively. The total operating lease cash payments for the three-month and six-month periods ended June 30, 2019 was $1,669,000 and $3,070,000, respectively. The total lease expense for leases with a term of twelve months or less for which the Company elected not to recognize a lease asset or lease liability was $64,000 and $233,000 for the three-month and six-month periods ended June 30, 2019, respectively.

Future operating lease cash payments are as follows (in thousands):

Year Ended December 31,	Amount
Remainder of fiscal 2019	$	3,387
2020	5,730
2021	4,397
2022	2,890
2023	2,035
2024	842
Thereafter	311
	$	19,592

The discounted present value of the future lease cash payments resulted in a lease liability of $17,984,000 as of June 30, 2019.

The weighted-average discount rate was 4.8% for the leases outstanding as of June 30, 2019. The weighted-average remaining lease term was 3.6 years for the leases outstanding as of June 30, 2019. The Company did not have any leases that have not yet commenced but that create significant rights and obligations as of June 30, 2019.

The Company owns a building adjacent to its corporate headquarters that is partially occupied with a tenant who has a lease agreement that will expire in 2022. Rental income was $81,000 and $83,000 for the three-month period ended June 30, 2019 and July 1, 2018, respectively. Rental income was $158,000 and $159,000 for the six-month period ended June 30, 2019 and July 1, 2018, respectively.

Warranty Obligations

Warranty Obligations

The Company records the estimated cost of fulfilling product warranties at the time of sale based upon historical costs to fulfill claims. Obligations may also be recorded subsequent to the time of sale whenever specific events or circumstances impacting product quality become known that would not have been taken into account using historical data. While we engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers and third-party contract manufacturers, the Company’s warranty obligation is affected by product failure rates, material usage, and service delivery costs incurred in correcting a product failure. An adverse change in any of these factors may result in the need for additional warranty provisions. Warranty obligations are included in “Accrued expenses” on the Consolidated Balance Sheets.

The changes in the warranty obligation were as follows (in thousands):

Derivative Instruments

Derivative Instruments

The Company’s foreign currency risk management strategy is principally designed to mitigate the potential financial impact of changes in the value of transactions and balances denominated in foreign currencies resulting from changes in foreign currency exchange rates. Currently, the Company enters into economic hedges to manage this risk. The economic hedges utilize foreign currency forward contracts with maturities of up to 45 days to manage the exposure to fluctuations in foreign currency exchange rates arising primarily from foreign-denominated receivables and payables. The gains and losses on these derivatives are intended to be offset by the changes in the fair value of the assets and

liabilities being hedged. These economic hedges are not designated as hedging instruments for hedge accounting treatment.

The Company had the following outstanding forward contracts (in thousands):

Costs to Fulfill a Contract

Costs to fulfill a contract are included in "Prepaid expenses and other current assets" on the Consolidated Balance Sheet and amounted to $6,852,000 and $3,514,000 as of June 30, 2019 and December 31, 2018, respectively.

Accounts Receivable, Contract Assets, and Contract Liabilities

Accounts receivable represent amounts billed and currently due from customers which are reported at their net estimated realizable value. The Company maintains reserves against its accounts receivable for potential credit losses. Credit losses recognized on accounts receivable were immaterial for the three-month and six-month periods ended June 30, 2019 and July 1, 2018, respectively.

Stock-Based Compensation Expense

Stock-Based Compensation Expense

The Company’s share-based payments that result in compensation expense consist of stock option grants and restricted stock awards. As of June 30, 2019, the Company had 17,363,952 shares available for grant. Stock options are granted with an exercise price equal to the market value of the Company’s common stock at the grant date and generally vest over four or five years based upon continuous service and expire ten years from the grant date.

The following table summarizes the Company’s stock option activity for the six-month period ended June 30, 2019:

	Shares (in thousands)		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)
Outstanding as of December 31, 2018	13,789		$	31.73
Granted	2,821		51.37
Exercised	(1,239	)	21.32
Forfeited or expired	(606	)	40.27
Outstanding as of June 30, 2019	14,765		$	36.00	7.42	$	207,599
Exercisable as of June 30, 2019	5,867		$	25.12	5.95	$	138,370
Options vested or expected to vest as of June 30, 2019 (1)	13,214		$	34.65	7.25	$	201,420

 (1) In addition to the vested options, the Company expects a portion of the unvested options to vest at some point in the future. Options expected to vest are calculated by applying an estimated forfeiture rate to the unvested options.

The fair values of stock options granted in each period presented were estimated using the following weighted-average assumptions:

	Three-months Ended				Six-months Ended
	June 30, 2019		July 1, 2018		June 30, 2019		July 1, 2018
Risk-free rate	2.7	%	2.9	%	2.7	%	2.9	%
Expected dividend yield	0.39	%	0.32	%	0.39	%	0.32	%
Expected volatility	37	%	39	%	37	%	39	%
Expected term (in years)	5.2		5.4		5.3		5.3

Risk-free rate

The risk-free rate was based upon a treasury instrument whose term was consistent with the contractual term of the option.

Expected dividend yield

Generally, the current dividend yield is calculated by annualizing the cash dividend declared by the Company’s Board of Directors and dividing that result by the closing stock price on the grant date. 

Expected volatility

The expected volatility was based upon a combination of historical volatility of the Company’s common stock over the contractual term of the option and implied volatility for traded options of the Company’s stock.

Expected term

The expected term was derived from the binomial lattice model from the impact of events that trigger exercises over time.

The Company stratifies its employee population into two groups: one consisting of senior management and another consisting of all other employees. The Company currently applies an estimated annual forfeiture rate of 9% to all unvested options for senior management and a rate of 12% for all other employees. Each year during the first quarter, the Company revises its estimated forfeiture rate. This resulted in a decrease to compensation expense of $499,000 in 2019 and in increase to compensation expense of $1,283,000 in 2018.

The weighted-average grant-date fair values of stock options granted during the three-month periods ended June 30, 2019 and July 1, 2018 were $18.68 and $21.63, respectively. The weighted-average grant-date fair values of stock options granted during the six-month periods ended June 30, 2019 and July 1, 2018 were $18.59 and $21.62, respectively.

The total intrinsic values of stock options exercised for the three-month periods ended June 30, 2019 and July 1, 2018 were $14,220,000 and $4,902,000, respectively. The total intrinsic values of stock options exercised for the six-month periods ended June 30, 2019 and July 1, 2018 were $36,799,000 and $32,991,000, respectively. The total fair values of stock options vested for the three-month periods ended June 30, 2019 and July 1, 2018 were $887,000 and $887,000, respectively. The total fair values of stock options vested for the six-month periods ended June 30, 2019 and July 1, 2018 were $30,859,000 and $26,560,000, respectively.

As of June 30, 2019, total unrecognized compensation expense related to non-vested stock options was $66,645,000, which is expected to be recognized over a weighted-average period of 1.88 years.

The total stock-based compensation expense and the related income tax benefit recognized for the three-month period ended June 30, 2019 were $10,967,000 and $1,813,000, respectively, and for the three-month period ended July 1, 2018 were $9,002,000 and $1,607,000, respectively. The total stock-based compensation expense and the related income tax benefit recognized for the six-month period ended June 30, 2019 were $23,248,000 and $4,035,000, respectively, and for the six-month period ended July 1, 2018 were $22,196,000 and $3,954,000, respectively. No compensation expense was capitalized as of June 30, 2019 or December 31, 2018.

Management has determined that earnings from its legal entity in China will be indefinitely reinvested to provide sufficient local funding for growth, and that earnings from all other jurisdictions will not be indefinitely reinvested. The Company is tax resident in numerous jurisdictions around the world and has identified its major tax jurisdictions as the United States, Ireland, and China. The statutory tax rate is 12.5% in Ireland and 25% in China, compared to the U.S. federal statutory corporate tax rate of 21%. International rights to certain of the Company's intellectual property are held by a subsidiary whose legal jurisdiction does not tax this income, resulting in a foreign effective tax rate that is lower than

the above mentioned statutory rates, although the reduced taxes overseas have been partially offset by changes in U.S. tax law. These differences resulted in a decrease in the effective tax rate by 7 percentage points for all periods presented.

The excess tax benefit arising from the difference between the deduction for tax purposes and the compensation cost recognized for financial reporting purposes from stock option exercises resulted in a decrease in the effective tax rate by 2 and 1 percentage points for the three-month periods ended June 30, 2019 and July 1, 2018, respectively, and a decrease in the effective tax rate by 4 and 5 percentage points for the six-month periods ended June 30, 2019 and July 1, 2018, respectively.

During the six-month period ended June 30, 2019, the Company recorded a $952,000 increase in reserves for income taxes, net of deferred tax benefit. Estimated interest and penalties included in these amounts totaled $155,000 for the six-month period ended June 30, 2019.

The Company’s reserve for income taxes, including gross interest and penalties, was $9,119,000 as of June 30, 2019, which included $8,091,000 classified as a non-current liability and $1,028,000 recorded as a reduction to non-current deferred tax assets. The amount of gross interest and penalties included in these balances was $1,019,000. If the Company’s tax positions were sustained or the statutes of limitations related to certain positions expired, these reserves would be released and income tax expense would be reduced in a future period. As a result of the expiration of certain statutes of limitations, there is a potential that a portion of these reserves could be released, which would decrease income tax expense by approximately $1,250,000 to $1,350,000 over the next twelve months.

The Company has defined its major tax jurisdictions as the United States, Ireland, and China, and within the United States, Massachusetts. Within the United States, the tax years 2015 through 2018 remain open to examination by the Internal Revenue Service and various state tax authorities. The tax years 2014 through 2018 remain open to examination by various taxing authorities in other jurisdictions in which the Company operates.

Summary of Significant Accounting Policies (Policies)

Jun. 30, 2019

Accounting Policies [Abstract]

Leases

As permitted by the rules of the Securities and Exchange Commission applicable to Quarterly Reports on Form 10-Q, these notes are condensed and do not contain all disclosures required by generally accepted accounting principles (GAAP). As a result of the adoption of ASC 842 "Leases," Cognex Corporation (the "Company") has provided new disclosures related to leases in this Quarterly Report on Form 10-Q. Reference should be made to the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 for a full description of other significant accounting policies.

In the opinion of the management of the Company, the accompanying consolidated unaudited financial statements contain all adjustments, consisting of normal, recurring adjustments, and financial statement reclassifications necessary to present fairly the Company’s financial position as of June 30, 2019, and the results of its operations for the three-month and six-month periods ended June 30, 2019 and July 1, 2018, and changes in shareholders’ equity, comprehensive income, and cash flows for the periods presented.

The results disclosed in the Consolidated Statements of Operations for the three-month and six-month periods ended June 30, 2019 are not necessarily indicative of the results to be expected for the full year.

Leases

The Company accounts for leases in accordance with Accounting Standard Codification (ASC) 842, "Leases." The core principle of ASC 842 is that a lessee should recognize on the balance sheet the assets and liabilities that arise from leases.

At inception of a contract, the Company determines whether that contract is or contains a lease. The Company determines whether a contract contains a lease by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset for a period of time in exchange for consideration. The Company has control of the asset if it has the right to direct the use of the asset and obtains substantially all of the economic benefits from the use of the asset throughout the period of use.

As a practical expedient, the Company does not recognize a lease asset or lease liability for leases with a lease term of 12 months or less. In the determination of the lease term, the Company considers the existence of extension or termination options and the probability of those options being exercised.

Lease contracts may include lease components and non-lease components, such as common area maintenance and utilities for property leases. As a practical expedient, the Company accounts for the non-lease components together with the lease components as a single lease component for all of its leases.

The Company classifies a lease as a finance lease when it meets any of the following criteria at the lease commencement date: a) the lease transfers ownership of the underlying asset to the Company by the end of the lease term; b) the lease grants the Company an option to purchase the underlying asset that the Company is reasonably certain to exercise; c) the lease term is for the major part of the remaining economic life of the underlying asset (the Company considers a major part to be 75% or more of the remaining economic life of the underlying asset); d) the present value of the sum of the lease payments and any residual value guaranteed by the Company equals or exceeds substantially all of the fair value of the underlying asset (the Company considers substantially all the fair value to be 90% or more of the fair value of the underlying asset amount); or e) the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. When none of the criteria above are met, the Company classifies the lease as an operating lease.

On the lease commencement date, the Company records a lease asset and lease liability on the balance sheet. The lease asset consists of: 1) the amount of the initial lease liability; 2) any lease payments made to the lessor at or before the lease commencement date, minus any lease incentives received; and 3) any initial direct cost incurred by the Company. Initial direct costs are incremental costs of a lease that would not have been incurred if the lease had not been obtained and are capitalized as part of the lease asset.

The lease liability equals the present value of the future cash payments discounted using the Company's incremental borrowing rate. The Company’s incremental borrowing rate is the rate of interest that the Company would have to pay to borrow an amount equal to the lease payments over a similar term, which is the three-month London Interbank Offered Rate (LIBOR) plus a 2.5% credit risk spread.

Operating lease expense equals the total cash payments recognized on a straight-line basis over the lease term. The amortization of the lease asset is calculated as the straight-line lease expense less the accretion of the interest on the lease liability each period. The lease liability is reduced by the cash payment less the interest each period.

New Pronouncements

ew Pronouncements

Accounting Standards Update (ASU) 2016-13, "Financial Instruments - Measurement of Credit Losses"

ASU 2016-13 applies to all reporting entities holding financial assets that are not accounted for at fair value through net income (debt securities).  The amendments in this ASU eliminate the probable initial recognition threshold to recognize a credit loss under current U.S. GAAP and, instead, reflect an entity’s current estimate of all expected credit losses. In addition, this ASU broadens the information an entity must consider in developing the credit loss estimate, including the use of reasonable and supportable forecasted information.  The amendments in this ASU require that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down and an entity will be able to record reversals of credit losses in current period net income. For public companies, the guidance in ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods.  This ASU should be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective.  Management does not expect ASU 2016-13 to have a material impact on the Company's financial statements and disclosures.

Accounting Standards Update (ASU) 2017-08, "Receivables - Nonrefundable Fees and Other Costs - Premium Amortization on Purchased Callable Debt Securities"

ASU 2017-08 applies to all reporting entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date (that is, at a premium). The amendments in this ASU shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. Under current GAAP, premiums and discounts on callable debt securities generally are amortized to the maturity date. If that callable debt security is subsequently called, the entity records a loss equal to the unamortized premium. The amendments in this ASU more closely align the amortization period of premiums and discounts to expectations incorporated in market pricing on the underlying securities. For public companies, the amendments in ASU 2017-08 are effective for annual periods beginning after December 15, 2019 and interim reporting periods within annual years beginning after December 15, 2020. This ASU should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption, and, in the period of adoption, the entity is required to provide disclosures about the change in accounting principle. Early adoption is permitted, including adoption in an interim period. Management does not expect ASU 2017-08 to have a material impact on the Company's financial statements and disclosures.

Accounting Standards Update (ASU) 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software"

ASU 2018-15 applies to entities that are a customer in a hosting arrangement that is a service contract. The amendments in this ASU align 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. Accordingly, the amendments in this ASU require an entity in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. Further, it requires the entity to expense the capitalized implementation costs over the term of the hosting arrangement. In addition, it requires the presentation of the expenses related to the capitalized implementation costs in the same line item in the statement of income as the fees associated with the hosting element of the arrangement and the classification of the payments for the capitalized implementation costs in the statement of cash flows in the same manner as the payments made for the fees associated with the hosting element. The amendments in this ASU are effective for public entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. Management does not expect ASU 2018-15 to have a material impact on the Company's financial statements and disclosures.
