inTEST CORPORATION

INDEX

We are a global supplier of innovative test and process solutions for use in manufacturing and testing across a wide range of markets including automotive, defense/aerospace, industrial, medical, semiconductor and telecommunications. We manage our business as two operating segments which are also our reportable segments and reporting units: Thermal Products ("Thermal") and Electromechanical Solutions ("EMS"). Our Thermal segment designs, manufactures and sells our thermal test and thermal process products while our EMS segment designs, manufactures and sells our semiconductor test products. We manufacture our products in the U.S. Marketing and support activities are conducted worldwide from our facilities in the U.S., Germany, Singapore, the Netherlands and the U.K. The consolidated entity is comprised of inTEST Corporation and our wholly-owned subsidiaries.

Our EMS segment sells its products to semiconductor manufacturers and third-party test and assembly houses (end user sales) and to automated test equipment (“ATE”) manufacturers (original equipment manufacturer (“OEM”) sales), who ultimately resell our equipment with theirs to both semiconductor manufacturers and third-party test and assembly houses. These sales all fall within the ATE sector of the broader semiconductor market. Our Thermal segment sells its products to many of these same types of customers; however, it also sells to customers in the wafer processing sector within the broader semiconductor market and to customers in a variety of other markets outside the semiconductor market, including the automotive, defense/aerospace, industrial (including consumer products packaging, fiber optics and other sectors within the broader industrial market), medical and telecommunications markets.

Both of our operating segments have multiple products that we design, manufacture and market to our customers. Due to a number of factors, our products have varying levels of gross margin. The mix of products we sell in any period is ultimately determined by our customers' needs. Therefore, the mix of products sold in any given period can change significantly from the prior period. As a result, our consolidated gross margin can be significantly impacted in any given period by a change in the mix of products sold in that period.

We refer to the broader semiconductor market, including the more specialized ATE and wafer processing sectors within that market, as the “Semi Market.” All other markets are designated as “Multimarket.” The Semi Market, which is the principal market in which we operate, is characterized by rapid technological change, competitive pricing pressures and cyclical market patterns. This market is subject to significant economic downturns at various times.

Our financial results are affected by a wide variety of factors, including, but not limited to, general economic conditions worldwide and in the markets in which we operate, economic conditions specific to the Semi Market and the other markets we serve, our ability to safeguard patented technology and intellectual property in a rapidly evolving market, downward pricing pressures from customers, and our reliance on a relatively few number of customers for a significant portion of our sales. In addition, we are exposed to the risk of obsolescence of our inventory depending on the mix of future business and technological changes within the markets that we serve. Part of our strategy for growth includes potential acquisitions that may cause us to incur substantial expense in the review and evaluation of potential transactions. We may or may not be successful in locating suitable businesses to acquire or in closing acquisitions of businesses we pursue. In addition, we may not be able to successfully integrate any business we do acquire with our existing business and we may not be able to operate the acquired business profitably. As a result of these or other factors, we may experience significant period-to-period fluctuations in our future operating results.

COVID-19 Pandemic

Demand from all of the markets we serve was significantly affected by COVID-19 during the first half of 2020. The impact of COVID-19 on demand from the Semi Market was intensified during the first half of 2020 because our business operations were also being negatively affected by a global downturn in the Semi Market at that time. The Semi Market, from which approximately half of our orders and net revenues are derived, entered a cyclical downturn in the beginning of 2019. During the first quarter of 2020, before the spread of COVID-19, we had started to see indications that the downturn was coming to an end. These indications included increased quoting activity and order levels for the first quarter of 2020 compared to the fourth quarter of 2019. However, we believe COVID-19 delayed the recovery in the Semi Market as the increase in activity leveled off during late March 2020. Although we saw slightly increased order rates from our customers in the Semi Market during the second and third quarters of 2020, it was not until the fourth quarter of 2020 that we saw a significant increase in our orders from the Semi Market, which we believe indicates that we have now entered the next cyclical upturn. During the fourth quarter of 2020, our orders from the Semi Market increased 53% sequentially and were 141% higher than in the fourth quarter of 2019, the low point of the prior cyclical downturn for the products that we sell. This trend in our orders from the Semi Market continued in the first quarter of 2021 with a further 54% sequential increase from the level in the fourth quarter of 2020. We believe the level of increase in our orders and net revenues from the Semi Market during the fourth quarter of 2020 and the first quarter of 2021 reflects a combination of increased demand in the market resulting from the interruption of the normal recovery in the Semi Market cycle caused by the onset of COVID-19 in the first half of 2020, as well as increased demand for semiconductors, generally. We believe this increase in demand is being driven both by changing technology as well as increased use of technology across all aspects of daily life, such as in devices that facilitate remote work and education, smart technology used in homes and businesses, the increase in the number of integrated circuits used in the automotive industry and changes occurring in the telecommunications and mobility markets.

As of the date of this filing, all of our operations continue to be deemed “critical and essential business operations” under the various governmental COVID-19 mandates, which has allowed us to continue to operate our business with certain modifications. These modifications include a significant number of our employees working remotely. Such employees have been provided with the tools and technology necessary to do so. Additionally, we have implemented workplace safeguards designed to protect the health and well-being of our employees. Employees who remain in our facilities are following World Health Organization (“WHO”) and Centers for Disease Control and Prevention (“CDC”) recommended safety practices, as well as state and local directives. We have had occasions where one or more employees have contracted COVID-19 and entered our facilities while infected. To date, we have managed these occurrences with minimal disruption to our business while protecting other employees, but there can be no assurances that we can avoid similar occurrences in the future or, that in such cases, we can avoid significant disruption of our operations.

The aftermarket service and support that we provide to our customers has been, and we expect may continue to be, adversely impacted by COVID-19. Specifically, the travel restrictions that remain in place, coupled with limitations on visitors into customer facilities, have resulted in the reduction or suspension of in-person service and support activities. The net revenues associated with these aftermarket service and support activities typically range from 8% to 10% of our consolidated net revenues. Although these net revenues returned to a more typical range during the second half of 2020, they declined again in the first quarter of 2021. If the spread of COVID-19 or variations of the virus worsen, these revenues may continue to be reduced in future periods.

While the negative impact of COVID-19 on our business was reduced significantly in the second half of 2020 and the first quarter of 2021, the spread of the virus or variants of the virus could worsen and one or more of our significant customers or suppliers could be impacted, or significant additional governmental regulations and restrictions could be imposed, thus negatively impacting our business in the future. As a result of our current level of working capital as well as the availability of our revolving credit facility, which is discussed in Note 9, we currently expect to have sufficient liquidity to operate our business throughout 2021. Our revolving credit facility, which had no outstanding balance, was set to mature on April 9, 2021. As discussed in Note 14, we modified this facility on April 10, 2021 and extended it as modified through April 9, 2024.

Basis of Presentation and Use of Estimates

The accompanying consolidated financial statements include our accounts and those of our wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated upon consolidation. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires us 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain of our accounts, including inventories, long-lived assets, goodwill, identifiable intangibles and deferred tax assets and liabilities including related valuation allowances, are particularly impacted by estimates.
 

In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the financial position, results of operations, and changes in cash flows for the interim periods presented. Certain footnote information has been condensed or omitted from these consolidated financial statements. Therefore, these consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying footnotes included in our Form 10-K for the year ended December 31, 2020 (“2020 Form 10-K”) filed on March 23, 2021 with the Securities and Exchange Commission.

Reclassification

Certain prior period amounts have been reclassified to be comparable with the current period's presentation.

Subsequent Events

We have made an assessment of our operations and determined that there were no material subsequent events requiring adjustment to, or disclosure in, our consolidated financial statements for the three months ended March 31, 2021 other than those described in Note 14.

Business Combinations

Acquired businesses are accounted for using the purchase method of accounting, which requires that the purchase price be allocated to the net assets acquired at their respective fair values. Any excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Fair values of intangible assets are estimated by valuation models prepared by our management and third-party advisors. The assets purchased and liabilities assumed have been reflected in our consolidated balance sheets, and the results are included in the consolidated statements of operations and consolidated statements of cash flows from the date of acquisition. Any change in the fair value of acquisition-related contingent consideration subsequent to the acquisition date, including changes from events after the acquisition date, will be recognized in the consolidated statement of operations in the period of the estimated fair value change. Acquisition-related transaction costs, including legal and accounting fees and other external costs directly related to the acquisition, are recognized separately from the acquisition and expensed as incurred in general and administrative expense in the consolidated statements of operations.

Restructuring and Other Charges

In accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 420 (Exit or Disposal Cost Obligations), we recognize a liability for restructuring costs at fair value only when the liability is incurred. Workforce-related charges are accrued when it is determined that a liability has been incurred, which is generally after individuals have been notified of their termination dates and expected severance benefits. Depending on the timing of the termination dates, these charges may be recognized upon notification or ratably over the remaining required service period of the employees. Plans to consolidate excess facilities may result in lease termination fees and impairment charges related to our right-of-use (“ROU”) assets that are associated with the leases for these facilities. Other long-lived assets that may be impaired as a result of restructuring consist of property and equipment, goodwill and intangible assets. Asset impairment charges included in restructuring and other charges are based on an estimate of the amounts and timing of future cash flows related to the expected future remaining use and ultimate sale or disposal of the asset, and, in the case of our ROU assets, would include expected future sublease rental income, if applicable. These estimates are derived using the guidance in ASC Topic 842 (Leases), ASC Topic 360 (Property, Plant and Equipment) and ASC Topic 350 (Intangibles - Goodwill and Other).

Goodwill, Intangible and Long-Lived Assets

We account for goodwill and intangible assets in accordance with ASC Topic 350 (Intangibles - Goodwill and Other). Finite-lived intangible assets are amortized over their estimated useful economic life and are carried at cost less accumulated amortization. Goodwill is assessed for impairment annually in the fourth quarter on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. Goodwill is considered to be impaired if the fair value of a reporting unit is less than its carrying amount. As a part of the goodwill impairment assessment, we have the option to perform a qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. If, as a result of our qualitative assessment, we determine that it is more-likely-than-not that the fair value of the reporting unit is greater than its carrying amount, a quantitative goodwill impairment test is not required. However, if, as a result of our qualitative assessment, we determine it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, or, if we choose not to perform a qualitative assessment, we are required to perform a quantitative goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized.

The quantitative goodwill impairment test compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss will be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. The goodwill impairment assessment is based upon the income approach, which estimates the fair value of our reporting units based upon a discounted cash flow approach. This fair value is then reconciled to our market capitalization at year end with an appropriate control premium. The determination of the fair value of our reporting units requires management to make significant estimates and assumptions, including the selection of control premiums, discount rates, terminal growth rates, forecasts of revenue and expense growth rates, income tax rates, changes in working capital, depreciation, amortization and capital expenditures. Changes in assumptions concerning future financial results or other underlying assumptions could have a significant impact on either the fair value of the reporting unit or the amount of the goodwill impairment charge.

Indefinite-lived intangible assets are assessed for impairment annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that the asset might be impaired. As a part of the impairment assessment, we have the option to perform a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired. If, as a result of our qualitative assessment, we determine that it is more-likely-than-not that the fair value of the indefinite-lived intangible asset is less than its carrying amount, the quantitative impairment test is required; otherwise, no further testing is required. The quantitative impairment test consists of a comparison of the fair value of the intangible asset with its carrying amount. If the carrying amount of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.

Long-lived assets, which consist of finite-lived intangible assets, property and equipment and ROU assets, are assessed for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the estimated undiscounted cash flows to the recorded value of the asset. If impairment is indicated, the asset is written down to its estimated fair value. The cash flow estimates used to determine the impairment, if any, contain management's best estimates using appropriate assumptions and projections at that time.

Revenue Recognition

We recognize revenue in accordance with the guidance in ASC Topic 606 (Revenue from Contracts with Customers). We recognize revenue for the sale of products or services when our performance obligations under the terms of a contract with a customer are satisfied and control of the product or service has been transferred to the customer. Generally, this occurs when we ship a product or perform a service. In certain cases, recognition of revenue is deferred until the product is received by the customer or at some other point in the future when we have determined that we have satisfied our performance obligations under the contract. Our contracts with customers may include a combination of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. In addition to the sale of products and services, we also lease certain of our equipment to customers under short-term lease agreements. We recognize revenue from equipment leases on a straight-line basis over the lease term. 

Revenue is recorded in an amount that reflects the consideration we expect to receive in exchange for those products or services. We do not have any material variable consideration arrangements, or any material payment terms with our customers other than standard payment terms which generally range from net 30 to net 90 days. We generally do not provide a right of return to our customers. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities.

Nature of Products and Services

We are a global supplier of innovative test and process solutions for use in manufacturing and testing across a wide range of markets including automotive, defense/aerospace, industrial, medical, semiconductor and telecommunications. We sell thermal management products including ThermoStreams, ThermoChambers and process chillers, which we sell under our Temptronic, Sigma and Thermonics product lines, and Ambrell Corporation’s (“Ambrell”) precision induction heating systems, including EKOHEAT and EASYHEAT products. We sell semiconductor ATE interface solutions which include manipulators, docking hardware and electrical interface products. We provide post-warranty service for the equipment we sell. We sell semiconductor ATE interface solutions and certain thermal management products to the Semi Market. We also sell our thermal management products to various other markets including the automotive, defense/aerospace, industrial, medical and telecommunications markets.

We lease certain of our equipment under short-term leasing agreements with original lease terms of six months or less. Our lease agreements do not contain purchase options.

Types of Contracts with Customers  

Our contracts with customers are generally structured as individual purchase orders which specify the exact products or services being sold or equipment being leased along with the selling price, service fee or monthly lease amount for each individual item on the purchase order. Payment terms and any other customer-specific acceptance criteria are also specified on the purchase order. We generally do not have any customer-specific acceptance criteria, other than that the product performs within the agreed upon specifications. We test substantially all products manufactured as part of our quality assurance process to determine that they comply with specifications prior to shipment to a customer.

Contract Balances  

We record accounts receivable at the time of invoicing. Accounts receivable, net of the allowance for doubtful accounts, is included in current assets on our balance sheet. To the extent that we do not recognize revenue at the same time as we invoice, we record a liability for deferred revenue. In certain instances, we also receive customer deposits in advance of invoicing and recording of accounts receivable. Deferred revenue and customer deposits are included in current liabilities on our consolidated balance sheets.

The allowance for doubtful accounts reflects our best estimate of probable losses inherent in the accounts receivable balance. We determine the allowance based on known troubled accounts, if any, historical experience, and other currently available evidence.

Costs to Obtain a Contract with a Customer 

The only costs we incur associated with obtaining contracts with customers are sales commissions that we pay to our internal sales personnel or third-party sales representatives. These costs are calculated based on set percentages of the selling price of each product or service sold. Commissions are considered earned by our internal sales personnel at the time we recognize revenue for a particular transaction. Commissions are considered earned by third-party sales representatives at the time that revenue is recognized for a particular transaction. We record commission expense in our consolidated statements of operations at the time the commission is earned. Commissions earned but not yet paid are included in current liabilities on our balance sheets.

Product Warranties

In connection with the sale of our products, we generally provide standard one- or two-year product warranties which are detailed in our terms and conditions and communicated to our customers. Our standard warranties are not offered for sale separately from our products; therefore, there is not a separate performance obligation related to our standard warranties. We record estimated warranty expense for our standard warranties at the time of sale based upon historical claims experience. We offer customers an option to separately purchase an extended warranty on certain products. In the case of extended warranties, we recognize revenue in the amount of the sale price for the extended warranty on a straight-line basis over the extended warranty period. We record costs incurred to provide service under an extended warranty at the time the service is provided. Warranty expense is included in selling expense in our consolidated statements of operations. 

Refer to Notes 5 and 13 for further information about our revenue from contracts with customers.

Inventories

Inventories are valued at cost on a first-in, first-out basis, not in excess of market value. Cash flows from the sale of inventories are recorded in operating cash flows. On a quarterly basis, we review our inventories and record excess and obsolete inventory charges based upon our established objective excess and obsolete inventory criteria. Our criteria identify excess material as the quantity of material on hand that is greater than the average annual usage of that material over the prior three years. Effective January 1, 2021, our criteria identify obsolete material as material that has not been used in a work order during the prior twenty-four months. Prior to January 1, 2021, these criteria identified obsolete material as material that had not been used in a work order during the prior twelve months. In certain cases, additional excess and obsolete inventory charges are recorded based upon current market conditions, anticipated product life cycles, new product introductions and expected future use of the inventory. The excess and obsolete inventory charges we record establish a new cost basis for the related inventories. We incurred excess and obsolete inventory charges of $39 and $171 for the three months ended March 31, 2021 and 2020, respectively. The change in our estimate of obsolete material that was effective as of January 1, 2021 reflects changes that have occurred in the markets we serve and the business cycles within those markets. This change in estimate did not have a material impact on our consolidated financial statements.

Leases

We account for leases in accordance with ASC Topic 842 (Leases) which was effective for us as of January 1, 2019. Upon adoption of ASC Topic 842, we elected the package of practical expedients which included the grandfathering of the lease classification that had been made under prior guidance and, accordingly, we did not re-evaluate any of our leases for classification purposes in connection with the implementation of ASC Topic 842. All our lease contracts are still being treated as operating leases. We do not currently have any lease contracts that meet the criteria to be categorized as finance leases. We did not elect the hindsight practical expedient and therefore did not reevaluate the lease terms that we used under prior guidance. The implementation of ASC Topic 842 had a significant impact on our consolidated balance sheet as a result of recording ROU assets and lease liabilities for all our multi-year leases. Under prior guidance, none of these leases had any related asset recorded on our balance sheets. The only related liability recorded on our balance sheets was the amount which represented the difference between the lease payments we had made and the straight-line rent expense we had recorded in our statements of operations. The implementation of ASC Topic 842 did not have a significant impact on our pattern of expense recognition for any of our multi-year leases.

We determine if an arrangement is a lease at inception. A lease contract is within scope if the contract has an identified asset (property, plant or equipment) and grants the lessee the right to control the use of the asset during the lease term. The identified asset may be either explicitly or implicitly specified in the contract. In addition, the supplier must not have any practical ability to substitute a different asset and would not economically benefit from doing so for the lease contract to be in scope. The lessee’s right to control the use of the asset during the term of the lease must include the ability to obtain substantially all the economic benefits from the use of the asset as well as decision-making authority over how the asset will be used. Leases are classified as either operating leases or finance leases based on the guidance in ASC Topic 842. Operating leases are included in operating lease ROU assets and operating lease liabilities in our consolidated balance sheets. Finance leases are included in property and equipment and finance lease liabilities. We do not currently have any finance leases. We do not have embedded leases nor do we have any initial direct costs related to our lease contracts.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. None of our leases provide an implicit rate; therefore, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease. We include these options in the determination of the amount of the ROU asset and lease liability when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Certain of our operating leases contain predetermined fixed escalations of minimum rentals and rent holidays during the original lease terms. Rent holidays are periods during which we have control of the leased facility but are not obligated to pay rent. For these leases, our ROU asset and lease liability are calculated including any rent holiday in the determination of the life of the lease.

We have lease agreements which contain both lease and non-lease components, which are generally accounted for separately. In addition to the monthly rental payments due, most of our leases for our offices and warehouse facilities include non-lease components representing our portion of the common area maintenance, property taxes and insurance charges incurred by the landlord for the facilities which we occupy. These amounts are not included in the calculation of the ROU assets and lease liabilities as they are based on actual charges incurred in the periods to which they apply.

Operating lease payments are included in cash outflows from operating activities on our consolidated statements of cash flows. Amortization of ROU assets is presented separately from the change in operating lease liabilities and is included in depreciation and amortization in our consolidated statements of cash flows.

We have made an accounting policy election not to apply the recognition requirements of ASC Topic 842 to short-term leases (leases with a term of one year or less at the commencement date of the lease). Lease expense for short-term lease payments is recognized on a straight-line basis over the lease term.

See Note 8 for further disclosures regarding our leases. 

Contingent Liability for Repayment of State and Local Grant Proceeds

In connection with leasing a new facility in Rochester, New York, which our subsidiary, Ambrell, occupied in May 2018, we entered into agreements with the city of Rochester and the state of New York under which we received grants totaling $463 to help offset a portion of the cost of the leasehold improvements we have made to this facility. In exchange for the funds we received under these agreements, we are required to create and maintain specified levels of employment in this location through various dates ending in 2023. If we fail to meet these employment targets, we may be required to repay a proportionate share of the proceeds. As of March 31, 2021, $370 of the total proceeds received could still be required to be repaid if we do not meet the targets. We have recorded this amount as a contingent liability which is included in other liabilities on our balance sheet. Those portions of the proceeds which are no longer subject to repayment are reclassified to deferred grant proceeds and amortized to income on a straight-line basis over the remaining lease term for the Rochester facility. Deferred grant proceeds are included in other current liabilities and other liabilities on our balance sheet and totaled $81 at March 31, 2021.

As of December 31, 2020, we were not in compliance with the employment targets as specified in the grant agreement with the city of Rochester. We applied for and received a waiver of this requirement for the year ended December 31, 2020. The waiver provided us until December 31, 2021 to come into compliance with the targets as outlined in the waiver. As of March 31, 2021, we were in compliance with those targets.

Stock-Based Compensation

We account for stock-based compensation in accordance with ASC Topic 718 (Compensation - Stock Compensation), which requires that employee share-based equity awards be accounted for under the fair value method and requires the use of an option pricing model for estimating fair value of stock options granted, which is then amortized to expense over the service periods. See further disclosures related to our stock-based compensation plan in Note 10.

Income Taxes

The asset and liability method is used in accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for operating loss and tax credit carryforwards and for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period that includes the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if it is more likely than not that such assets will not be realized.

Net Earnings (Loss) Per Common Share

Net earnings (loss) per common share - basic is computed by dividing net earnings (loss) by the weighted average number of common shares outstanding during each period. Net earnings (loss) per common share - diluted is computed by dividing net earnings (loss) by the weighted average number of common shares and common share equivalents outstanding during each period. Common share equivalents represent unvested shares of restricted stock and stock options and are calculated using the treasury stock method. Common share equivalents are excluded from the calculation if their effect is anti-dilutive.

The table below sets forth, for the periods indicated, a reconciliation of weighted average common shares outstanding - basic to weighted average common shares and common share equivalents outstanding - diluted and the average number of potentially dilutive securities that were excluded from the calculation of diluted earnings per share because their effect was anti-dilutive:

Effect of Recently Issued Amendments to Authoritative Accounting Guidance

In June 2016, the Financial Accounting Standards Board (“FASB”) issued amendments to the guidance for accounting for credit losses. In November 2019, the FASB deferred the effective date of these amendments for certain companies, including smaller reporting companies. As a result of the deferral, the amendments are effective for us for reporting periods beginning after December 15, 2022. The amendments replace the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires the use of a forward-looking expected credit loss model for accounts receivables, loans, and other financial instruments. The amendments require a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We plan to adopt the amendments when they become effective for us on January 1, 2023. We do not currently expect that the adoption of these amendments will have a material impact on our consolidated financial statements.

EMS Segment Restructuring and Facility Consolidation

On September 21, 2020, we notified employees in our Fremont, California facility of a plan to consolidate all manufacturing for our EMS segment into our manufacturing operations located in Mt. Laurel, New Jersey. The consolidation was substantially completed during the fourth quarter of 2020 and resulted in the termination of employment for certain employees at the Fremont location. Prior to the consolidation, our interface products were manufactured in the Fremont facility, and our manipulator and docking hardware products were manufactured in the Mt. Laurel facility. The consolidation was undertaken to better serve customers through streamlined operations and reduce the fixed annual operating costs for the EMS segment. A small engineering and sales office will be maintained in northern California.

As a result of the consolidation, we incurred charges for severance and other one-time termination benefits, other associated costs, including moving and production start-up costs, and charges related to exiting the facility, including an impairment charge related to the ROU asset for the lease of the Fremont facility, which are more fully discussed in Note 3 to our consolidated financial statements in our 2020 Form 10-K. During the first quarter of 2021, we incurred $55 of additional charges associated with finalizing the integration of the manufacturing operations. All of these charges were cash charges. We expect to complete the integration in the second quarter of 2021 and expect to incur additional cash charges in the range of $50 to $100.

Other Restructuring Actions

During the first quarter of 2020, we recorded cash charges for severance and other one-time termination benefits of $8 related to headcount reductions in our corporate office.

Accrued Restructuring

The liability for accrued restructuring charges is included in other current liabilities on our consolidated balance sheet. Changes in the amount of the liability for accrued restructuring for the three months ended March 31, 2021 is as follows:

We have two operating segments which are also our reporting units: Thermal and EMS. Goodwill and intangible assets on our balance sheets are the result of our acquisitions of Sigma Systems Corp. ("Sigma") in October 2008, Thermonics, Inc. ("Thermonics") in January 2012 and Ambrell in May 2017. All our goodwill and intangible assets are allocated to our Thermal segment.

The following tables provide further detail about our intangible assets as of March 31, 2021 and December 31, 2020:

We generally amortize our finite-lived intangible assets over their estimated useful lives on a straight-line basis, unless an alternate amortization method can be reliably determined. Any such alternate amortization method would be based on the pattern in which the economic benefits of the intangible asset are expected to be consumed. None of our intangible assets have any residual value.

Total amortization expense for our finite-lived intangible assets was $304 and $311, respectively, for the three months ended March 31, 2021 and 2020. The following table sets forth the estimated annual amortization expense for each of the next five years:

Letters of Credit

We have issued letters of credit as security deposits for certain of our domestic leases. These letters of credit are secured by pledged certificates of deposit which are classified as Restricted Certificates of Deposit on our balance sheets. The terms of our leases require us to renew these letters of credit at least 30 days prior to their expiration dates for successive terms of not less than one year until lease expiration.

Our outstanding letters of credit at March 31, 2021 and December 31, 2020 consisted of the following:

Line of Credit

As discussed more fully in Note 10 to our consolidated financial statements in our 2020 Form 10-K, on April 10, 2020, we entered into a Loan and Security Agreement (the “Agreement”) with M&T Bank (“M&T”). Under the terms of the Agreement, M&T has provided us with a $7,500 revolving credit facility which is guaranteed by our subsidiaries. This facility was put in place to provide us with additional liquidity in response to the current business environment, as a result of the COVID-19 pandemic. This facility, which had no outstanding balance, was set to mature on April 9, 2021. As discussed in Note 14, we modified this facility on April 10, 2021 and extended it as modified through April 9, 2024.

As of March 31, 2021, we had unvested restricted stock awards and stock options outstanding which were granted under stock-based compensation plans that are described more fully in Note 13 to the consolidated financial statements in our 2020 Form 10-K.

Our unvested restricted stock awards and stock options are accounted for based on their grant date fair value. As of March 31, 2021, total compensation expense to be recognized in future periods is $2,787. The weighted average period over which this expense is expected to be recognized is 2.8 years. The following table shows the allocation of the compensation expense we recorded during the three months ended March 31, 2021 and 2020, respectively, related to stock-based compensation:

There was no stock-based compensation expense capitalized in the three months ended March 31, 2021 or 2020.

Restricted Stock Awards

We record compensation expense for restricted stock awards based on the quoted market price of our stock at the grant date and amortize the expense over the vesting period. Restricted stock awards generally vest over four years for employees and over one year for our independent directors (25% at each of March 31, June 30, September 30, and December 31 of the year in which they were granted).

On August 24, 2020, our new President and CEO received two restricted stock awards totaling 141,610 shares valued at $650 as of the date of grant, which was also his hire date. Of the total shares awarded, 66,448 shares vest over 4 years (25% at each anniversary) and 75,162 vest on the third anniversary of the grant date at a vesting percentage that could range from 0% to 150% of the number of shares awarded on August 24, 2020. The final vesting percentage will be based on the achievement of certain performance metrics, including net revenue compound annual growth rate and diluted earnings per share excluding amortization of intangibles, for specified time periods as determined by the Compensation Committee of our Board of Directors. As of March 31, 2021, we have estimated that these shares will vest at 100% of the original amount awarded and are recording expense based on this estimate on a straight-line basis over the three-year vesting period. Our estimate of the final expected vesting percentage is reassessed and adjusted, as needed, at the end of each reporting period.

On March 10, 2021 we issued restricted stock awards totaling 18,000 shares to members of the senior management within our operating segments. These shares will vest on the third anniversary of the grant date at a vesting percentage that could range from 0% to 150% of the number of shares awarded on March 10, 2021. The final vesting percentage will be based on the achievement of certain performance metrics related to the operating results of the business units for which these members of management are responsible. As of March 31, 2021, we have estimated that these shares will vest at 100% of the original amount awarded and are recording expense based on this estimate on a straight-line basis over the three-year vesting period. Our estimate of the final expected vesting percentage is reassessed and adjusted, as needed, at the end of each reporting period.

The following table summarizes the activity related to unvested shares of restricted stock for the three months ended March 31, 2021:

The total fair value of the shares that vested during the three months ended March 31, 2021 and 2020 was $244 and $155, respectively, as of the vesting dates of these shares.

Stock Options

We record compensation expense for stock options based on the fair value of the options as of the grant date. No option may be granted with an exercise period in excess of ten years from the date of grant. Generally, stock options will be granted with an exercise price equal to the fair market value of our stock on the date of grant and will vest over four years. 

The fair value for stock options granted during the three months ended March 31, 2021 and 2020 was estimated at the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions:

The per share weighted average fair value of stock options issued during the three months ended March 31, 2021 and 2020 was $5.09 and $1.55, respectively.

The following table summarizes the activity related to stock options for the three months ended March 31, 2021:

On July 31, 2019, our Board of Directors authorized the repurchase of up to $3,000 of our common stock from time to time on the open market, in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or in privately negotiated transactions pursuant to a newly authorized stock repurchase plan (the “2019 Repurchase Plan”). Repurchases may be made under a Rule 10b5-1 plan entered into with RW Baird & Co., which would permit shares to be repurchased when we might otherwise be precluded from doing so under insider trading laws and our internal trading windows. The 2019 Repurchase Plan does not obligate us to purchase any particular amount of common stock and may be suspended or discontinued at any time without prior notice. The 2019 Repurchase Plan is funded using our operating cash flow or available cash. Purchases began on September 18, 2019 under this plan. On March 2, 2020, we suspended repurchases under the 2019 Repurchase Plan. For the term of the 2019 Repurchase Plan through March 31, 2021, we have repurchased a total of 243,075 shares at a cost of $1,216, which includes fees paid to our broker of $6. All of the repurchased shares were retired.

We have defined contribution 401(k) plans for our employees who work in the U.S. All permanent employees of inTEST Corporation, inTEST EMS LLC, Temptronic Corporation and inTEST Silicon Valley Corporation who are at least 18 years of age are eligible to participate in the inTEST Corporation Incentive Savings Plan. We match employee contributions dollar for dollar up to 10% of the employee's annual compensation, with a maximum limit of $5. Employer contributions vest ratably over four years. Matching contributions are discretionary. For the three months ended March 31, 2021 and 2020, expense under the plan was $171 and $165, respectively.

All permanent employees of Ambrell are immediately eligible to participate in the Ambrell Corporation Savings & Profit Sharing Plan (the "Ambrell Plan") upon employment and are eligible for employer matching contributions after completing six months of service, as defined in the Ambrell Plan. The Ambrell Plan allows eligible employees to make voluntary contributions up to 100% of compensation, up to the federal government contribution limits. We will make a matching contribution of 50% of each employee's contributions up to a maximum of 10% of the employee's deferral with a maximum limit of $5. For the three months ended March 31, 2021 and 2020, expense under the plan was $43 and $17, respectively.

We have two reportable segments, Thermal and EMS, which are also our reporting units. Thermal includes the operations of Temptronic, Thermonics, Sigma, inTEST Thermal Solutions GmbH (Germany), inTEST Pte, Limited (Singapore) and Ambrell. Sales of this segment consist primarily of temperature management systems which we design, manufacture and market under our Temptronic, Thermonics and Sigma product lines, and precision induction heating systems which are designed, manufactured and marketed by Ambrell. In addition, this segment provides post-warranty service and support. EMS includes the operations of our manufacturing facilities in Mt. Laurel, New Jersey and, prior to the consolidation of manufacturing operations late in the fourth quarter of 2020, Fremont, California. Sales of this segment consist primarily of manipulator, docking hardware and tester interface products, which we design, manufacture and market.

We operate our business worldwide and sell our products both domestically and internationally. Both of our segments sell to semiconductor manufacturers, third-party test and assembly houses and ATE manufacturers. Thermal also sells into a variety of markets outside of the Semi Market, including the automotive, defense/aerospace, medical, industrial, telecommunications and other markets.

The following table provides information about our geographic areas of operation. Net revenues from unaffiliated customers are based on the location to which the goods are shipped.

On April 10, 2021, we amended our Agreement with M&T, with the execution of the Second Amendment to the Agreement (the “Second Amendment”). Under the terms of the Second Amendment, the maximum amount available under the revolving credit facility was increased from $7,500 to $10,000, and an unused facility fee of fifteen basis points per annum was added. This facility was amended to provide us with additional liquidity to operate our business, if needed. This facility will mature on April 9, 2024.
