BUSINESS DESCRIPTION AND SIGNIFICANT ACCOUNTING POLICIES [Abstract]
BUSINESS DESCRIPTION AND SIGNICANT ACCOUNTING POLICIES	NOTE 1 – BUSINESS DESCRIPTION AND SIGNIFICANT ACCOUNTING POLICIES Description of Business We are a leading global developer and manufacturer of high precision 3D sensors and systems for inspection and metrology. We also develop and manufacture our WaferSense® products, a family of wireless, wafer-shaped sensors that provide measurements of critical factors in the semiconductor fabrication process. Our sensors and system products are used in surface mount technology (SMT) and semiconductor markets to significantly improve yields and productivity. Principles of Consolidation The consolidated financial statements include the accounts of CyberOptics Corporation and its wholly-owned subsidiaries. In these notes to the consolidated financial statements, these companies are collectively referred to as “CyberOptics,” “we,” “us,” or “our.” All significant inter-company accounts and transactions have been eliminated in consolidation. Segment Reporting We operate in a single reportable segment that includes the design, development and manufacture of high precision sensing, inspection and metrology solutions for the SMT and semiconductor markets. Use of Estimates The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Cash and Cash Equivalents We consider all highly liquid investments purchased with an original maturity of 90 days or less to be cash equivalents. Cash and cash equivalents consist of funds maintained in demand deposit accounts, money market accounts, corporate debt instruments and U.S. government backed obligations. Cash and cash equivalent balances, at times, may exceed federally insured limits. Marketable Securities All marketable securities are classified as available-for-sale and consist of U.S. government and agency backed obligations, certificates of deposit, corporate debt instruments, asset backed securities or equity securities. Marketable securities are classified as short-term or long-term in the consolidated balance sheets based on their maturity date and expectations regarding sales. Available-for-sale securities are carried at fair value. Unrealized gains and losses for marketable debt securities are reported as a separate component of stockholders’ equity until realized. Unrealized gains and losses for marketable equity securities are recognized in net income. Fair values are primarily determined using quoted market prices. The carrying amounts of securities, for purposes of computing unrealized gains and losses, are determined by specific identification. The cost of securities sold is also determined by specific identification. We monitor the carrying value of our marketable debt securities compared to their fair value to determine whether an other-than-temporary impairment has occurred. Factors considered in determining whether a loss is other-than-temporary include the length of time and extent to which fair value has been less than the cost basis, credit quality and our ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. If a decline in fair value of our marketable debt securities is determined to be other-than-temporary, an impairment charge related to that specific investment is recorded in net income. Cash and marketable securities held by foreign subsidiaries totaled $327,000 at December 31, 2019 and $362,000 at December 31, 2018. Inventories Inventories are stated at the lower of cost or net realizable value, with cost determined using the first-in, first-out (FIFO) method. Appropriate consideration is given to deterioration, obsolescence, and other factors in evaluating net realizable value. Accounts and Trade Notes Receivable We extend unsecured credit to our customers in the normal course of business. In the fourth quarter of 2019, we provided financing to a recurring customer for the purchase of SQ3000™ Multi-Function inspection and measurement machines. The trade notes receivable bear interest at an annual effective rate of approximately 7%, and are repayable over a 36-month period. The current portion of the notes are classified as accounts receivable in the accompanying balance sheets. Interest income will be discontinued for any trade notes receivable with a specific reserve established if it is likely that we will be unable to collect all amounts due according to the original terms of the trade notes. For these trade notes receivable, cash collection will first be applied as a reduction to principal outstanding. Any cash received in excess of the outstanding principal payments will be recognized as interest income. Trade notes receivable may be removed from non-accrual status with respect to interest income based upon changes in customer circumstances, including a sustained history of payments. At December 31, 2019, none of our trade notes receivable were in a non-accrual status with respect to interest income. Allowance for Doubtful Accounts and Trade Notes Allowances for doubtful accounts are maintained for estimated losses resulting from the inability of our customers to make required payments. In making the determination of the appropriate allowance for doubtful accounts, we consider specific accounts, historical write-offs, changes in customer relationships and credit worthiness and concentrations of credit risk. Specific accounts and trade notes receivable are written-off once a determination is made that the account is uncollectible. Equipment and Leasehold Improvements Equipment and leasehold improvements are stated at cost. Significant additions or improvements extending asset lives are capitalized, while repairs and maintenance are charged to expense as incurred. In-progress costs are capitalized with depreciation beginning when assets are placed in service. Depreciation is recorded using the straight-line method over the estimated useful lives of the equipment, ranging from one to seven years. Leasehold improvements are amortized using the straight-line method over the shorter of the asset useful life or the underlying lease term, ranging from one to eight years. Gains or losses on dispositions are included in current operations. Goodwill Goodwill represents the excess of purchase price over the fair value of net assets acquired in a business combination. We have determined that we have one reporting unit. We evaluate the carrying value of goodwill annually on December 31st and more frequently if management believes indicators of impairment exist. Such indicators could include, but are not limited to (1) a significant adverse change in legal factors or in business climate, (2) unanticipated competition, or (3) an adverse action or assessment by a regulator. We first assess qualitative factors to determine whether it is more likely than not that our fair value is greater than carrying value (i.e. net book value). If we conclude that it is more likely than not that our fair value is greater than carrying value, no further testing is required. If we conclude that it is more likely than not that our fair value is less than carrying value, we conduct a two-step quantitative goodwill impairment test. The first step of the impairment test involves comparing our fair value to carrying value. We estimate our fair value using the income approach. The income approach is a valuation technique under which we estimate future cash flows using financial forecasts. Future estimated cash flows are discounted to their present value to calculate fair value. When considering fair value, we also give consideration to the control premium in excess of our current market capitalization that might be obtained from a third party acquirer. If we determine that our carrying value exceeds fair value, the amount of impairment loss must be measured. The second step of the goodwill impairment test involves comparing the implied fair value of our goodwill with the carrying value of that goodwill. The amount by which the carrying value of the goodwill exceeds its implied value, if any, is recognized as an impairment loss. On December 31, 2019 and 2018, we performed a qualitative assessment to determine if there was any indication that our goodwill might be impaired. After considering all available evidence, including our financial performance, financial outlook and current market capitalization, we concluded that it is more likely than not that our fair value is greater than carrying value. As a result, no further testing was deemed necessary, and we determined that our goodwill was not impaired. Therefore, no amounts were recorded for goodwill impairment in 2019 or 2018. Patents Patents consist of legal and patent registration costs for protection of our proprietary technology. We amortize patent costs on a straight-line basis, based upon their estimated life. Long Lived Assets Intangible assets subject to amortization and other long-lived assets are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An impairment loss would be recognized when future undiscounted cash flows expected to result from use of the asset and eventual disposition are less than the carrying amount. Revenue Recognition Revenue is measured based on consideration specified in the contract with a customer. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account for purposes of revenue recognition. Revenue from all customers, including distributors, is recognized when a performance obligation is satisfied by transferring control of a product or service to a customer. Amounts billed to customers for shipping and handling are included in revenue. All shipping and handling costs associated with outbound freight are accounted for as fulfillment costs and are included in cost of sales. Taxes collected from customers and remitted to governmental authorities are excluded from revenue on the net basis of accounting. Accounts receivable are due under normal trade terms, typically 120 days or less. Our performance obligations are mostly satisfied at a point in time and to a lesser extent over time as work progresses. Revenue for products and services transferred to customers at a point in time is recognized when obligations under the terms of the contract with our customer are satisfied; generally with the transfer of control upon shipment. Sales of some products may require customer acceptance due to performance or other acceptance criteria that is considered more than a formality. For these product sales, revenue is recognized upon notification of customer acceptance. Sales involving multiple performance obligations typically include the sale of an inspection or metrology systems product, installation and training, and in some cases, an extended warranty. When a sale involves multiple performance obligations, we account for individual products and services separately if the customer can benefit from the product or service on its own or with other resources that are readily available to the customer and the product or service are separately identifiable from other promises in the arrangement. Undelivered performance obligations in an arrangement are typically minimal, consisting of undelivered installation and training services. The consideration is allocated between separate performance obligations in proportion to their estimated stand-alone selling price. If the stand-alone selling price is not directly observable, we use the cost plus margin approach to estimate stand-alone selling price. Costs related to products delivered are recognized in the period revenue is recognized; including product warranties for periods ranging from 1 to 3 years (see Note 8). Periodically, sensor product arrangements with our original equipment manufacturers (OEM's) will create an asset with no alternative use and include an enforceable right to payment. For these arrangements, control is transferred over the manufacturing process; therefore, revenue is recognized over time utilizing an input method based on actual costs incurred in the manufacturing process to date relative to total expected production costs. For certain longer duration 3D scanning service projects, we progress bill as the services are performed. These arrangements create an asset with no alternative use and include an enforceable right to payment. For these arrangements, control is transferred over the hours incurred to complete the scanning project; therefore, revenue is recognized over time utilizing an input method based on actual hours incurred relative to total projected project hours. For maintenance and extended warranty contracts, revenue is recognized over time on a straight-line basis over the term of the contract as the customer simultaneously receives and consumes the benefits of the coverage. *Practical Expedients* We generally expense the incremental costs of obtaining a contract when incurred because the amortization period for these costs would be less than one year. These costs primarily relate to sales commissions and are recorded in selling, general and administrative expense in our consolidated statements of operations. We do not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less, primarily consisting of product installation and training. We do not adjust the promised amount of consideration for the effects of a significant financing component if we expect, at contract inception, that the period between when we transfer a promised good or service to a customer and when the customer pays for that good or service will be one year or less. Foreign Currency Translation Financial position and results of operations of our international subsidiaries are measured using local currency as their functional currency. Assets and liabilities of these operations are translated at the exchange rates in effect at each fiscal year-end. Statements of operations accounts are translated at the average rates of exchange prevailing during the year. Translation adjustments arising from the use of differing exchange rates from period to period are included as a cumulative translation adjustment in stockholders’ equity. Foreign Currency Transactions Foreign currency transaction gains and losses are included in interest income and other, net in the statement of operations. We recognized a foreign currency transaction loss of $127,000 in 2019 and a foreign currency transaction gain of $72,000 in 2018. Research and Development Research and development (R&D) costs, including product software development, are expensed when incurred. Product software development costs are required to be expensed until the point that technological feasibility and proven marketability of the product are established; costs otherwise capitalizable after such point also are expensed because they are insignificant. All other R&D costs are expensed as incurred. R&D expenses consist primarily of salaries, project materials, contract labor and other costs associated with ongoing product development and enhancement efforts. Advertising Costs We expense all advertising costs as incurred. Advertising expense incurred was $408,000 in 2019 and $314,000 in 2018. Warranty Costs We provide for the estimated cost of product warranties, which cover products for periods ranging from one to three years at the time revenue is recognized. Income Taxes We evaluate uncertain tax positions using the “more likely than not” threshold (i.e., a likelihood of occurrence greater than fifty percent). The recognition threshold is met when an entity concludes that a tax position, based solely on its technical merits, is more likely than not to be sustained upon examination by the relevant taxing authority. Those tax positions failing to qualify for initial recognition are classified as a gross unrecognized tax benefit until the first interim period in which they meet the more likely than not standard, or are resolved through negotiation or litigation with the taxing authority, or upon expiration of the statute of limitations. De-recognition of a tax position that was previously recognized occurs when an entity subsequently determines that a tax position no longer meets the more likely than not threshold of being sustained. Only the portion of the unrecognized tax benefit that is expected to be paid within one year is classified as a current liability. As a result, liabilities expected to be resolved without the payment of cash (e.g., resolution due to the expiration of the statute of limitations) or are not expected to be paid within one year are not classified as current. It is our policy to record estimated interest and penalties as income tax expense and tax credits as a reduction in income tax expense. Deferred income taxes are recorded to reflect the tax consequences in future years of differences between the financial reporting and tax bases of assets and liabilities. Income tax expense is the sum of the tax currently payable and the change in the deferred tax assets and liabilities during the period, excluding changes in deferred tax assets recorded to goodwill. Valuation allowances are established when, in the opinion of management, there is uncertainty that some portion or all of the deferred tax assets will not be realized. We assess the realizability of our deferred tax assets and the need for a valuation allowance based on all positive and negative evidence. Net Income Per Share Basic net income per basic share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Net income per diluted share is computed by dividing net income by the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares consist of common shares to be issued upon exercise of stock options, vesting of restricted stock units, vesting of restricted shares and from purchases of shares under our employee stock purchase plan, as calculated using the treasury stock method. Common equivalent shares are excluded from the calculation of net income per diluted share if their effect is anti-dilutive. Fair Value of Financial Instruments The carrying amounts of financial instruments such as cash equivalents, accounts receivable, other assets, accounts payable, advance customer payments, accrued expenses and other liabilities approximate their related fair values due to the short-term maturities of these instruments. The fair value for trade notes receivable is based on discounted future cash flows using current interest rates that would be offered for a similar transaction to a similarly situated customer. The difference between the carrying amount and estimated fair value for trade notes receivable is immaterial. Share-Based Compensation All share-based payments to employees, including grants of stock options, are required to be recognized as an expense in our consolidated statements of operations based on the grant date fair value of the award. We utilize the straight-line method of expense recognition over the award’s service period for our graded vesting options. The fair value of stock options has been determined using the Black-Scholes model. We account for the impact of forfeitures related to employee share-based payment arrangements when the forfeitures occur. We have classified employee share-based compensation within our consolidated statements of operations in the same manner as our cash based employee compensation costs. See Note 6 to the consolidated financial statements for additional information related to employee share-based compensation. Related Party Transactions One of our board members serves as the President and Chief Executive Officer of Key Tronic Corporation, and our President and Chief Executive Officer serves on the board of Key Tronic Corporation. Our cumulative sales to Key Tronic Corporation in 2019 and 2018 were less than $20,000. Recent Accounting Developments On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers and related amendments (Topic 606), which provided guidance on the recognition of revenue from contracts with customers. Topic 606 requires disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. We performed a review of the requirements of the new guidance and identified which of our revenue streams are within the scope of Topic 606. We applied the five-step model of the new standard to a selection of contracts within each of our revenue streams, and compared the results to our current accounting practices. We also expanded our consolidated financial statement disclosures to comply with the requirements of Topic 606. We adopted Topic 606 using the modified retrospective method, with the cumulative effect of initially applying the guidance to all uncompleted contracts as an adjustment to the opening balance of retained earnings. Our adoption of Topic 606 on January 1, 2018 resulted in a $218,000 decrease in retained earnings to record the cumulative effect adjustment. On January 1, 2018, we adopted ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities (ASU 2016-01), which revised the accounting related to (1) the classification and measurement of investments in equity securities and (2) the presentation of certain fair value changes for financial liabilities measured at fair value. The new standard also amended certain disclosure requirements associated with the fair value of financial instruments. ASU 2016-01 requires the fair value measurement of investments in equity securities and other ownership interests in an entity that do not result in consolidation and are not accounted for under the equity method. Entities are now required to recognize the change in the fair value of these investments in net income. Entities are no longer able to recognize unrealized holding gains and losses on equity securities in other comprehensive income. ASU 2016-01 was effective beginning January 1, 2018 and resulted in a cumulative-effect adjustment to beginning retained earnings, except for guidance relative to equity securities without readily determinable fair values, which was applied prospectively. Our adoption of ASU 2016-01 on January 1, 2018 resulted in a $44,000 increase in retained earnings and accumulated other comprehensive loss. In February 2016, the Financial Accounting Standards Board (FASB) issued new lease accounting guidance, ASU 2016-02, Leases (Topic 842), which we adopted on January 1, 2019. Under Topic 842, at the commencement date, lessees are required (a) to recognize a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis, and (b) to record a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842), Targeted Improvements, which gives companies the option of applying the new standard at the adoption date, rather than retrospectively to the earliest period presented in the financial statements, with recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. We chose the option to apply the new standard at the adoption date, and therefore we were not required to restate the financial statements of prior periods, nor were we required to provide the disclosures required by Topic 842 for those prior periods. Upon adoption of Topic 842, we recognized an approximate $2.6 million right-of-use asset, and an approximate $3.2 million lease liability. Our previously recognized liability for lease incentives recorded under prior accounting standards was eliminated. Our adoption of Topic 842 on January 1, 2019 resulted in a $33,000 increase in retained earnings to record the cumulative effect adjustment. Our adoption of Topic 842 did not impact our cash flows or have a material impact on our results of operations. We have expanded our consolidated financial statement disclosures to comply with the requirements of Topic 842. In February 2018, the FASB issued ASU 2018-02, Reclassification of Tax Effects from Accumulated Other Comprehensive Income (ASU 2018-02), which allows an entity to elect an option to reclassify the stranded tax effects related to the application of the Tax Cuts and Jobs Act (TCJA) from accumulated other comprehensive loss to retained earnings. ASU 2018-02 was effective January 1, 2019 and could be applied either in the period of adoption or retrospectively to all applicable periods. We did not elect to reclassify the stranded tax effects related to the application of the TCJA from accumulated other comprehensive loss to retained earnings. In January 2017, the FASB issued guidance on simplifying the test for goodwill impairment, ASU 2017-04, Simplifying the Test for Goodwill Impairment (ASU 2017-04). Under ASU 2017-04, goodwill impairment would be measured as the amount by which a reporting unit’s carrying value exceeds its fair value, but not in an amount in excess of the carrying value of goodwill. The new standard eliminates the requirement to determine goodwill impairment by calculating the implied fair value of goodwill by hypothetically assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. ASU 2017-04 is to be applied prospectively to impairment tests beginning January 1, 2020. We do not expect our adoption of ASU 2017-04 to have a material impact on our consolidated financial statements.

BUSINESS DESCRIPTION AND SIGNICANT ACCOUNTING POLICIES

NOTE 1 – BUSINESS DESCRIPTION AND SIGNIFICANT ACCOUNTING POLICIES

Description of Business

We are a leading global developer and manufacturer of high precision 3D sensors and systems for inspection and metrology. We also develop and manufacture our WaferSense® products, a family of wireless, wafer-shaped sensors that provide measurements of critical factors in the semiconductor fabrication process. Our sensors and system products are used in surface mount technology (SMT) and semiconductor markets to significantly improve yields and productivity.

Principles of Consolidation

The consolidated financial statements include the accounts of CyberOptics Corporation and its wholly-owned subsidiaries. In these notes to the consolidated financial statements, these companies are collectively referred to as “CyberOptics,” “we,” “us,” or “our.” All significant inter-company accounts and transactions have been eliminated in consolidation.

Segment Reporting

We operate in a single reportable segment that includes the design, development and manufacture of high precision sensing, inspection and metrology solutions for the SMT and semiconductor markets.

Use of Estimates

The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates.

Cash and Cash Equivalents

We consider all highly liquid investments purchased with an original maturity of 90 days or less to be cash equivalents. Cash and cash equivalents consist of funds maintained in demand deposit accounts, money market accounts, corporate debt instruments and U.S. government backed obligations. Cash and cash equivalent balances, at times, may exceed federally insured limits.

Marketable Securities

All marketable securities are classified as available-for-sale and consist of U.S. government and agency backed obligations, certificates of deposit, corporate debt instruments, asset backed securities or equity securities. Marketable securities are classified as short-term or long-term in the consolidated balance sheets based on their maturity date and expectations regarding sales.

Available-for-sale securities are carried at fair value. Unrealized gains and losses for marketable debt securities are reported as a separate component of stockholders’ equity until realized. Unrealized gains and losses for marketable equity securities are recognized in net income. Fair values are primarily determined using quoted market prices. The carrying amounts of securities, for purposes of computing unrealized gains and losses, are determined by specific identification. The cost of securities sold is also determined by specific identification.

We monitor the carrying value of our marketable debt securities compared to their fair value to determine whether an other-than-temporary impairment has occurred. Factors considered in determining whether a loss is other-than-temporary include the length of time and extent to which fair value has been less than the cost basis, credit quality and our ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. If a decline in fair value of our marketable debt securities is determined to be other-than-temporary, an impairment charge related to that specific investment is recorded in net income.

Cash and marketable securities held by foreign subsidiaries totaled $327,000 at December 31, 2019 and $362,000 at December 31, 2018.

Inventories

Inventories are stated at the lower of cost or net realizable value, with cost determined using the first-in, first-out (FIFO) method. Appropriate consideration is given to deterioration, obsolescence, and other factors in evaluating net realizable value.

Accounts and Trade Notes Receivable

We extend unsecured credit to our customers in the normal course of business. In the fourth quarter of 2019, we provided financing to a recurring customer for the purchase of SQ3000™ Multi-Function inspection and measurement machines. The trade notes receivable bear interest at an annual effective rate of approximately 7%, and are repayable over a 36-month period. The current portion of the notes are classified as accounts receivable in the accompanying balance sheets.

Interest income will be discontinued for any trade notes receivable with a specific reserve established if it is likely that we will be unable to collect all amounts due according to the original terms of the trade notes. For these trade notes receivable, cash collection will first be applied as a reduction to principal outstanding. Any cash received in excess of the outstanding principal payments will be recognized as interest income. Trade notes receivable may be removed from non-accrual status with respect to interest income based upon changes in customer circumstances, including a sustained history of payments. At December 31, 2019, none of our trade notes receivable were in a non-accrual status with respect to interest income.

Allowance for Doubtful Accounts and Trade Notes

Allowances for doubtful accounts are maintained for estimated losses resulting from the inability of our customers to make required payments. In making the determination of the appropriate allowance for doubtful accounts, we consider specific accounts, historical write-offs, changes in customer relationships and credit worthiness and concentrations of credit risk. Specific accounts and trade notes receivable are written-off once a determination is made that the account is uncollectible.

Equipment and Leasehold Improvements

Equipment and leasehold improvements are stated at cost. Significant additions or improvements extending asset lives are capitalized, while repairs and maintenance are charged to expense as incurred. In-progress costs are capitalized with depreciation beginning when assets are placed in service. Depreciation is recorded using the straight-line method over the estimated useful lives of the equipment, ranging from one to seven years. Leasehold improvements are amortized using the straight-line method over the shorter of the asset useful life or the underlying lease term, ranging from one to eight years. Gains or losses on dispositions are included in current operations.

Goodwill

Goodwill represents the excess of purchase price over the fair value of net assets acquired in a business combination. We have determined that we have one reporting unit. We evaluate the carrying value of goodwill annually on December 31st and more frequently if management believes indicators of impairment exist. Such indicators could include, but are not limited to (1) a significant adverse change in legal factors or in business climate, (2) unanticipated competition, or (3) an adverse action or assessment by a regulator. We first assess qualitative factors to determine whether it is more likely than not that our fair value is greater than carrying value (i.e. net book value). If we conclude that it is more likely than not that our fair value is greater than carrying value, no further testing is required. If we conclude that it is more likely than not that our fair value is less than carrying value, we conduct a two-step quantitative goodwill impairment test. The first step of the impairment test involves comparing our fair value to carrying value. We estimate our fair value using the income approach. The income approach is a valuation technique under which we estimate future cash flows using financial forecasts. Future estimated cash flows are discounted to their present value to calculate fair value. When considering fair value, we also give consideration to the control premium in excess of our current market capitalization that might be obtained from a third party acquirer. If we determine that our carrying value exceeds fair value, the amount of impairment loss must be measured. The second step of the goodwill impairment test involves comparing the implied fair value of our goodwill with the carrying value of that goodwill. The amount by which the carrying value of the goodwill exceeds its implied value, if any, is recognized as an impairment loss.

On December 31, 2019 and 2018, we performed a qualitative assessment to determine if there was any indication that our goodwill might be impaired. After considering all available evidence, including our financial performance, financial outlook and current market capitalization, we concluded that it is more likely than not that our fair value is greater than carrying value. As a result, no further testing was deemed necessary, and we determined that our goodwill was not impaired. Therefore, no amounts were recorded for goodwill impairment in 2019 or 2018.

Patents

Patents consist of legal and patent registration costs for protection of our proprietary technology. We amortize patent costs on a straight-line basis, based upon their estimated life.

Long Lived Assets

Intangible assets subject to amortization and other long-lived assets are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An impairment loss would be recognized when future undiscounted cash flows expected to result from use of the asset and eventual disposition are less than the carrying amount.

Revenue Recognition

Revenue is measured based on consideration specified in the contract with a customer. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account for purposes of revenue recognition. Revenue from all customers, including distributors, is recognized when a performance obligation is satisfied by transferring control of a product or service to a customer. Amounts billed to customers for shipping and handling are included in revenue. All shipping and handling costs associated with outbound freight are accounted for as fulfillment costs and are included in cost of sales. Taxes collected from customers and remitted to governmental authorities are excluded from revenue on the net basis of accounting. Accounts receivable are due under normal trade terms, typically 120 days or less.

Our performance obligations are mostly satisfied at a point in time and to a lesser extent over time as work progresses. Revenue for products and services transferred to customers at a point in time is recognized when obligations under the terms of the contract with our customer are satisfied; generally with the transfer of control upon shipment. Sales of some products may require customer acceptance due to performance or other acceptance criteria that is considered more than a formality. For these product sales, revenue is recognized upon notification of customer acceptance.

Sales involving multiple performance obligations typically include the sale of an inspection or metrology systems product, installation and training, and in some cases, an extended warranty. When a sale involves multiple performance obligations, we account for individual products and services separately if the customer can benefit from the product or service on its own or with other resources that are readily available to the customer and the product or service are separately identifiable from other promises in the arrangement. Undelivered performance obligations in an arrangement are typically minimal, consisting of undelivered installation and training services. The consideration is allocated between separate performance obligations in proportion to their estimated stand-alone selling price. If the stand-alone selling price is not directly observable, we use the cost plus margin approach to estimate stand-alone selling price. Costs related to products delivered are recognized in the period revenue is recognized; including product warranties for periods ranging from 1 to 3 years (see Note 8).

Periodically, sensor product arrangements with our original equipment manufacturers (OEM's) will create an asset with no alternative use and include an enforceable right to payment. For these arrangements, control is transferred over the manufacturing process; therefore, revenue is recognized over time utilizing an input method based on actual costs incurred in the manufacturing process to date relative to total expected production costs.

Practical Expedients

We generally expense the incremental costs of obtaining a contract when incurred because the amortization period for these costs would be less than one year. These costs primarily relate to sales commissions and are recorded in selling, general and administrative expense in our consolidated statements of operations.

We do not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less, primarily consisting of product installation and training. We do not adjust the promised amount of consideration for the effects of a significant financing component if we expect, at contract inception, that the period between when we transfer a promised good or service to a customer and when the customer pays for that good or service will be one year or less.

Foreign Currency Translation

Financial position and results of operations of our international subsidiaries are measured using local currency as their functional currency. Assets and liabilities of these operations are translated at the exchange rates in effect at each fiscal year-end. Statements of operations accounts are translated at the average rates of exchange prevailing during the year. Translation adjustments arising from the use of differing exchange rates from period to period are included as a cumulative translation adjustment in stockholders’ equity.

Foreign Currency Transactions

Foreign currency transaction gains and losses are included in interest income and other, net in the statement of operations. We recognized a foreign currency transaction loss of $127,000 in 2019 and a foreign currency transaction gain of $72,000 in 2018.

Research and Development

Research and development (R&D) costs, including product software development, are expensed when incurred. Product software development costs are required to be expensed until the point that technological feasibility and proven marketability of the product are established; costs otherwise capitalizable after such point also are expensed because they are insignificant. All other R&D costs are expensed as incurred. R&D expenses consist primarily of salaries, project materials, contract labor and other costs associated with ongoing product development and enhancement efforts.

Advertising Costs

We expense all advertising costs as incurred. Advertising expense incurred was $408,000 in 2019 and $314,000 in 2018.

Warranty Costs

We provide for the estimated cost of product warranties, which cover products for periods ranging from one to three years at the time revenue is recognized.

Income Taxes

We evaluate uncertain tax positions using the “more likely than not” threshold (i.e., a likelihood of occurrence greater than fifty percent). The recognition threshold is met when an entity concludes that a tax position, based solely on its technical merits, is more likely than not to be sustained upon examination by the relevant taxing authority. Those tax positions failing to qualify for initial recognition are classified as a gross unrecognized tax benefit until the first interim period in which they meet the more likely than not standard, or are resolved through negotiation or litigation with the taxing authority, or upon expiration of the statute of limitations. De-recognition of a tax position that was previously recognized occurs when an entity subsequently determines that a tax position no longer meets the more likely than not threshold of being sustained.

Only the portion of the unrecognized tax benefit that is expected to be paid within one year is classified as a current liability. As a result, liabilities expected to be resolved without the payment of cash (e.g., resolution due to the expiration of the statute of limitations) or are not expected to be paid within one year are not classified as current. It is our policy to record estimated interest and penalties as income tax expense and tax credits as a reduction in income tax expense.

Deferred income taxes are recorded to reflect the tax consequences in future years of differences between the financial reporting and tax bases of assets and liabilities. Income tax expense is the sum of the tax currently payable and the change in the deferred tax assets and liabilities during the period, excluding changes in deferred tax assets recorded to goodwill. Valuation allowances are established when, in the opinion of management, there is uncertainty that some portion or all of the deferred tax assets will not be realized. We assess the realizability of our deferred tax assets and the need for a valuation allowance based on all positive and negative evidence.

Net Income Per Share

Basic net income per basic share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Net income per diluted share is computed by dividing net income by the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares consist of common shares to be issued upon exercise of stock options, vesting of restricted stock units, vesting of restricted shares and from purchases of shares under our employee stock purchase plan, as calculated using the treasury stock method. Common equivalent shares are excluded from the calculation of net income per diluted share if their effect is anti-dilutive.

Fair Value of Financial Instruments

The carrying amounts of financial instruments such as cash equivalents, accounts receivable, other assets, accounts payable, advance customer payments, accrued expenses and other liabilities approximate their related fair values due to the short-term maturities of these instruments. The fair value for trade notes receivable is based on discounted future cash flows using current interest rates that would be offered for a similar transaction to a similarly situated customer. The difference between the carrying amount and estimated fair value for trade notes receivable is immaterial.

Share-Based Compensation

All share-based payments to employees, including grants of stock options, are required to be recognized as an expense in our consolidated statements of operations based on the grant date fair value of the award. We utilize the straight-line method of expense recognition over the award’s service period for our graded vesting options. The fair value of stock options has been determined using the Black-Scholes model. We account for the impact of forfeitures related to employee share-based payment arrangements when the forfeitures occur. We have classified employee share-based compensation within our consolidated statements of operations in the same manner as our cash based employee compensation costs.

See Note 6 to the consolidated financial statements for additional information related to employee share-based compensation.

Recent Accounting Developments

On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers and related amendments (Topic 606), which provided guidance on the recognition of revenue from contracts with customers. Topic 606 requires disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. We performed a review of the requirements of the new guidance and identified which of our revenue streams are within the scope of Topic 606. We applied the five-step model of the new standard to a selection of contracts within each of our revenue streams, and compared the results to our current accounting practices. We also expanded our consolidated financial statement disclosures to comply with the requirements of Topic 606. We adopted Topic 606 using the modified retrospective method, with the cumulative effect of initially applying the guidance to all uncompleted contracts as an adjustment to the opening balance of retained earnings. Our adoption of Topic 606 on January 1, 2018 resulted in a $218,000 decrease in retained earnings to record the cumulative effect adjustment.

On January 1, 2018, we adopted ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities (ASU 2016-01), which revised the accounting related to (1) the classification and measurement of investments in equity securities and (2) the presentation of certain fair value changes for financial liabilities measured at fair value. The new standard also amended certain disclosure requirements associated with the fair value of financial instruments. ASU 2016-01 requires the fair value measurement of investments in equity securities and other ownership interests in an entity that do not result in consolidation and are not accounted for under the equity method. Entities are now required to recognize the change in the fair value of these investments in net income. Entities are no longer able to recognize unrealized holding gains and losses on equity securities in other comprehensive income. ASU 2016-01 was effective beginning January 1, 2018 and resulted in a cumulative-effect adjustment to beginning retained earnings, except for guidance relative to equity securities without readily determinable fair values, which was applied prospectively. Our adoption of ASU 2016-01 on January 1, 2018 resulted in a $44,000 increase in retained earnings and accumulated other comprehensive loss.

In February 2016, the Financial Accounting Standards Board (FASB) issued new lease accounting guidance, ASU 2016-02, Leases (Topic 842), which we adopted on January 1, 2019. Under Topic 842, at the commencement date, lessees are required (a) to recognize a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis, and (b) to record a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842), Targeted Improvements, which gives companies the option of applying the new standard at the adoption date, rather than retrospectively to the earliest period presented in the financial statements, with recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. We chose the option to apply the new standard at the adoption date, and therefore we were not required to restate the financial statements of prior periods, nor were we required to provide the disclosures required by Topic 842 for those prior periods. Upon adoption of Topic 842, we recognized an approximate $2.6 million right-of-use asset, and an approximate $3.2 million lease liability. Our previously recognized liability for lease incentives recorded under prior accounting standards was eliminated. Our adoption of Topic 842 on January 1, 2019 resulted in a $33,000 increase in retained earnings to record the cumulative effect adjustment. Our adoption of Topic 842 did not impact our cash flows or have a material impact on our results of operations. We have expanded our consolidated financial statement disclosures to comply with the requirements of Topic 842.

In February 2018, the FASB issued ASU 2018-02, Reclassification of Tax Effects from Accumulated Other Comprehensive Income (ASU 2018-02), which allows an entity to elect an option to reclassify the stranded tax effects related to the application of the Tax Cuts and Jobs Act (TCJA) from accumulated other comprehensive loss to retained earnings. ASU 2018-02 was effective January 1, 2019 and could be applied either in the period of adoption or retrospectively to all applicable periods. We did not elect to reclassify the stranded tax effects related to the application of the TCJA from accumulated other comprehensive loss to retained earnings.

In January 2017, the FASB issued guidance on simplifying the test for goodwill impairment, ASU 2017-04, Simplifying the Test for Goodwill Impairment (ASU 2017-04). Under ASU 2017-04, goodwill impairment would be measured as the amount by which a reporting unit’s carrying value exceeds its fair value, but not in an amount in excess of the carrying value of goodwill. The new standard eliminates the requirement to determine goodwill impairment by calculating the implied fair value of goodwill by hypothetically assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. ASU 2017-04 is to be applied prospectively to impairment tests beginning January 1, 2020. We do not expect our adoption of ASU 2017-04 to have a material impact on our consolidated financial statements.
