NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(Dollars in thousands, except share data)

Note 1. Financial Statements

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all estimates and adjustments (consisting of normal recurring accruals, unless otherwise stated herein) considered necessary for a fair presentation of the financial position of L.B. Foster Company and subsidiaries as of September 30, 2020 and December 31, 2019, its Condensed Consolidated Statements of Operations, Condensed Consolidated Statements of Comprehensive Income, and its Condensed Consolidated Statements of Stockholders' Equity for the three and nine months ended September 30, 2020 and 2019, and its Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2020 and 2019, have been included. However, actual results could differ from those estimates. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. The Condensed Consolidated Balance Sheet as of December 31, 2019 was derived from audited financial statements. This Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and footnotes thereto included in L.B. Foster Company’s Annual Report on Form 10-K for the year ended December 31, 2019. In this Quarterly Report on Form 10-Q, references to “we,” “us,” “our,” and the “Company” refer collectively to L.B. Foster Company and its consolidated subsidiaries.

Recently Issued Accounting Standards

In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. (“ASU”) 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”), which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022. We are currently evaluating the impacts of the provisions of ASU 2020-04 on our financial condition, results of operations, and cash flows.

Recently Adopted Accounting Standards

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 added a new impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses and presents financial assets measured at amortized cost basis at the net amount expected to be collected upon inception. The CECL model applies to trade receivables, other receivables, and most debt instruments. The CECL model does not have a minimum threshold for recognition of impairment losses, and entities must measure expected credit losses on assets that have a low risk of loss. The Company adopted the provisions of ASU 2016-13 on January 1, 2020, using the modified retrospective approach as of the beginning of the period of adoption. In accordance with the standard, the Company evaluated its allowance for credit losses for trade receivables and contract assets, the only assets held by the Company that were impacted by the scope of the standard. The adoption of ASU 2016-13 had no material effect on the Company’s financial position or results of operations, and no adjustment to January 1, 2020 Retained earnings was recorded. The Company has presented the disclosures required by this new standard in Note 6 Accounts Receivable and Note 7 Inventory.

In August 2018, the FASB issued ASU 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software” (“ASU 2018-15”). ASU 2018-15 requires capitalization of certain implementation costs incurred in a cloud computing arrangement that qualifies as a service contract. The amendments in ASU 2018-15 are effective for fiscal years beginning after December 15, 2019 and for interim periods therein with early adoption permitted. The adoption of ASU 2018-15 had no impact on the Company’s consolidated financial statements and related disclosures.

Note 2. Business Segments

The Company is a leading manufacturer and distributor of products and provider of services for transportation and energy infrastructure with locations in North America and Europe. The Company's segments represent components of the Company (a) that engage in activities from which revenue is generated and expenses are incurred; (b) whose operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”), who uses such information to make decisions about resources to be allocated to the segments, and (c) for which discrete financial information is available. Operating segments are evaluated on their segment profit contribution to the Company's consolidated results. Other income and expenses, interest, income taxes, and certain other items are managed on a consolidated basis. The Company's segment accounting policies are the same as those described in Note 2. Business Segments of the Notes to the Company's Consolidated Financial Statements contained in its Annual Report on Form 10-K for the year-ended December 31, 2019.

The following table illustrates the Company's revenues and profit from operations by segment for the periods indicated:

	Three Months Ended September 30, 2020				Three Months Ended September 30, 2019

Total	$	381,835	$	19,565	$	475,097	$	35,811

Segment profit from operations, as shown above, includes allocated corporate operating expenses. Operating expenses related to corporate headquarter functions that directly support the segment activity are allocated based on segment headcount, revenue contribution, or activity of the business units within the segments, based on the corporate activity type provided to the segment. The expense allocation excludes certain corporate costs that are separately managed from the segments.

The following table provides a reconciliation of segment net profit from continuing operations to the Company’s consolidated continuing operations total for the periods presented:

	Three Months Ended September 30,				Nine Months Ended September 30,

Note 3. Discontinued Operations

Since the middle of 2019, the upstream energy markets that the Company served has deteriorated as prices of oil and natural gas declined due to weakening demand. This deterioration has recently accelerated as a result of the global COVID-19 pandemic and the associated reduction in demand due to reduced travel and movement of goods throughout the world. As U.S. exploration and production companies have reduced production and implemented spending cuts, demand for much of the Company’s offerings in its IOS Test and Inspection Services business had sharply declined. As a result, on September 4, 2020, the Company completed the sale of the issued and outstanding membership interests of its upstream oil and gas test and inspection business, IOS Acquisitions, LLC and subsidiaries (“Test and Inspection Services”). Proceeds from the sale were $4,000 and resulted in a loss of $10,034, net of tax. We have reflected the results of operations of the Test and Inspection Services business as discontinued operations in the Condensed Consolidated Financial Statements for all periods presented. The Test and Inspection Services business was historically included in the Tubular and Energy Services business segment.

(1) The assets of discontinued operations as of December 31, 2019 included $9,116 attributable to IOS Acquisitions, Inc. As part of the Company's restructuring activities in the second quarter of 2020, IOS Acquisitions, Inc. was converted to a limited liability company and subsequently treated as a disregarded entity for income tax purposes. As a result of this transaction, the deferred tax assets were not transferred upon the disposition of the Test and Inspection Services business.

Note 4. Revenue

Revenue from products or services provided to customers over time accounted for 32.2% and 35.6% of revenue for the three months ended September 30, 2020 and 2019, respectively, and 27.9% and 29.9% of revenue for the nine months ended September 30, 2020 and 2019, respectively. Revenue under these long-term agreements is generally recognized over time either using an input measure based upon the proportion of actual costs incurred to estimated total project costs or an input measure based upon actual labor costs as a percentage of estimated total labor costs, depending upon which measure the Company believes best depicts the Company’s performance to date under the terms of the contract. Revenue recognized over time using an input measure was $27,316 and $37,488 for the three months ended September 30, 2020 and 2019, respectively, and $76,606 and $104,309 for the nine months ended

11

September 30, 2020 and 2019, respectively. A certain portion of the Company’s revenue recognized over time under these long-term agreements is recognized using an output method, specifically units delivered, based upon certain customer acceptance and delivery requirements. Revenue recognized over time using an output measure was $10,800 and $14,031 for the three months ended September 30, 2020 and 2019, respectively, and $29,833 and $37,553 for the nine months ended September 30, 2020 and 2019, respectively. As of September 30, 2020 and December 31, 2019, the Company had contract assets of $36,891 and $37,032, respectively, that were recorded in “Inventories - net” within the Condensed Consolidated Balance Sheets. As of September 30, 2020 and December 31, 2019, the Company had contract liabilities of $3,606 and $4,472, respectively, that were recorded in “Deferred revenue” within the Condensed Consolidated Balance Sheets.

The majority of the Company’s revenue is from products transferred and services rendered to customers at a point in time. Point in time revenue accounted for 67.8% and 64.4% of revenue for the three months ended September 30, 2020 and 2019, respectively, and 72.1% and 70.1% of revenue for the nine months ended September 30, 2020 and 2019, respectively. The Company recognizes revenue at the point in time at which the customer obtains control of the product or service, which is generally when the product title passes to the customer upon shipment or the service has been rendered to the customer. In limited cases, title does not transfer and revenue is not recognized until the customer has received the products at a physical location.

The following table summarizes the Company's net sales by major product and service category for the periods presented:

The timing of revenue recognition, billings, and cash collections results in billed receivables, costs in excess of billings (contract assets, included in “Inventories - net”), and billings in excess of costs (contract liabilities, included in “Deferred revenue”) on the Condensed Consolidated Balance Sheets.

Significant changes in contract assets during the nine months ended September 30, 2020 resulted from transfers of $23,907 from the contract assets balance as of December 31, 2019 to receivables. Significant changes in contract liabilities during the nine months ended September 30, 2020 resulted from increases of $3,286 due to billings in excess of costs, excluding amounts recognized as revenue during the period. Contract liabilities were reduced due to revenue recognized during the three months ended September 30, 2020 and 2019 of $175 and $194, respectively, and reductions due to revenue recognized during the nine months ended September 30, 2020 and 2019 of $3,708 and $1,460, respectively, which were included in the contract liabilities at the beginning of each period.

As of September 30, 2020, the Company had approximately $235,190 of obligations under new contracts and remaining performance obligations, which is also referred to as backlog. Approximately 20.6% of the September 30, 2020 backlog was related to projects that are anticipated to extend beyond September 30, 2021.

Note 5. Goodwill and Other Intangible Assets

The following table presents the goodwill balance by reportable segment:

	Rail Products and Services		Construction Products		Tubular and Energy Services		Total

Balance as of September 30, 2020	$	14,210	$	5,613	$	—	$	19,823

The Company performs goodwill impairment tests annually during the fourth quarter, and also performs interim goodwill impairment tests if it is determined that it is more likely than not that the fair value of a reporting unit is less than the carrying amount. Qualitative factors are assessed to determine whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount, which included the impacts of COVID-19. However, the future impacts of COVID-19 are unpredictable and are subject to change. No interim goodwill impairment test was required as a result of the evaluation of qualitative factors as of September 30, 2020.

On August 17, 2020, the Company acquired LarKen Precast, LLC (“LarKen”) for $1,406, which is inclusive of an estimated $106 post-closing working capital adjustment, $250 which was withheld by the Company to satisfy any indemnity claims under the purchase agreement, and contingent considerations. Located in Boise, ID, LarKen is a manufacturer and provider of engineered precast concrete products and has been included in the Company’s Construction Products segment. The following table summarizes the estimates of the fair value of the goodwill and identifiable intangible assets acquired as of September 30, 2020:

		$	80,769	$	(38,656)	$	42,113

The Company amortizes intangible assets over their useful lives, which range from 5 to 25 years, with a total weighted average amortization period of approximately 16 years as of September 30, 2020. Amortization expense was $1,428 and $1,622 for the three months ended September 30, 2020 and 2019, respectively, and $4,271 and $4,947 for the nine months ended September 30, 2020 and 2019, respectively. During the nine months ended September 30, 2020, certain fully amortized intangible assets of $1,186 related to non-compete agreements were eliminated from gross intangible assets and accumulated amortization. As a result of the sale of Test and Inspection Services during the three months ended September 30, 2020, intangible assets related to customer relationships with gross carrying values of $1,893 and accumulated amortization of $587 were eliminated and are reflected in “Other assets of discontinued operations” as of December 31, 2019.

As of September 30, 2020, estimated amortization expense for the remainder of 2020 and thereafter was as follows:

	Amortization Expense
Remainder of 2020	$	1,452
2021	5,780
2022	5,694
2023	5,223
2024	4,210
2025 and thereafter	15,687
	$	38,046

Note 6. Accounts Receivable

The Company extends credit based upon an evaluation of the customer’s financial condition and, while collateral is not required, the Company periodically receives surety bonds that guarantee payment. Credit terms are consistent with industry standards and practices. The amounts of trade accounts receivable as of September 30, 2020 and December 31, 2019 have been reduced by an allowance for doubtful accounts of $1,176 and $1,073, respectively. Changes in reserves for uncollectable accounts, which are recorded as part of “Selling and administrative expenses” in the Condensed Consolidated Statements of Operations, resulted in income of $63 and $119 for the three months ended September 30, 2020 and 2019, respectively, and expense of $221 and income of $34 for the nine months ended September 30, 2020 and 2019, respectively.

On January 1, 2020, the Company adopted ASU 2016-13 and all the related amendments using the modified retrospective approach, which did not result in any changes to the previously reported financial information. The updates related to ASU 2016-13 were applied to assets held as of January 1, 2020.

In accordance with adoption of the new standard, the Company evaluated and revised its policies surrounding the allowance for credit losses for trade receivables. The Company established the allowance for credit losses by calculating the amount to reserve based on

14

the age of a given trade receivable and considering historical collection patterns and bad debt expense experience, in addition to any other relevant subjective adjustments to individual receivables made by management. The Company also considered current and expected future market and other conditions. Trade receivables are pooled within the calculation based on a range of ages, which appropriately groups receivables of similar credit risk together.

The established reserve thresholds to calculate the allowance for credit loss are based on and supported by historic collection patterns and bad debt expense incurred by the Company, as well as the expectation that collection patterns and bad debt expense will continue to adhere to patterns observed in recent years, which was formed based on trends observed as well as current and expected future conditions. Management maintains high-quality credit review practices as well as positive customer relationships that further mitigate credit risk. Management monitors and reviews the contributing factors to our reserve, and makes any appropriate revisions as they become necessary.

The Company’s adoption of ASU 2016-13 did not require material changes to the allowance for credit losses and no adjustment was recorded to opening retained earnings as of January 1, 2020.

Note 7. Inventory

Inventories as of September 30, 2020 and December 31, 2019 are summarized in the following table:

	September 30, 2020		December 31, 2019
Finished goods	$	63,462	$	59,024
Contract assets	36,891		37,032
Work-in-process	4,612		3,728
Raw materials	12,302		18,677
Inventories - net	$	117,267	$	118,461

Inventories of the Company are valued at average cost or net realizable value, whichever is lower.

In accordance with adoption of ASU 2016-13, the Company evaluated and revised its policies relating to the allowance for credit losses as they pertain to contract assets, as these assets held in inventory will convert to trade receivables upon recognition of revenue for the contract to which they pertain.

In addition to contract-specific provisions for which reserves were historically established as a result of our contract review process, management also elected to implement a standard credit loss provision over any remaining contract assets considered to have a similar low risk of credit loss.

The development of these estimates is based on historic collection trends, accuracy of estimates within contract margin reporting, as well as the expectation that collection patterns, margin reporting, and bad debt expense will continue to adhere to patterns observed in recent years. These expectations were formed based on trends observed as well as current and expected future conditions. Management monitors and reviews the contributing factors to our reserve, and makes any appropriate revisions as they become necessary.

Note 8. Property, Plant, and Equipment

Property, plant, and equipment as of September 30, 2020 and December 31, 2019 consisted of the following:

	September 30, 2020		December 31, 2019

The Company reviews its property, plant, and equipment for recoverability whenever events or changes in circumstances indicate that carrying amounts may not be recoverable. The Company recognizes an impairment loss if it believes that the carrying amount of a

15

long-lived asset is not recoverable and exceeds its fair value. There were no impairments of property, plant, and equipment during the three and nine months ended September 30, 2020 and 2019.

Note 9. Leases

The Company determines if an arrangement is a lease at its inception. Operating leases are included in “Operating lease right-of-use assets - net,” “Other accrued liabilities,” and “Long-term operating lease liabilities” within the Condensed Consolidated Balance Sheets. Finance leases are included in “Property, plant, and equipment - net,” “Current maturities of long-term debt,” and “Long-term debt” in the Condensed Consolidated Balance Sheets.

The Company has operating and finance leases for manufacturing facilities, corporate offices, sales offices, vehicles, and certain equipment.

On June 26, 2020, the Company, its domestic subsidiaries, and certain of its Canadian and United Kingdom subsidiaries (collectively, the “Borrowers”), entered into the First Amendment (the “First Amendment”) to its Third Amended and Restated Credit Agreement (the “Credit Agreement”) with PNC Bank, N.A., Bank of America, N.A., Wells Fargo Bank, N.A., Citizens Bank, N.A., and BMO Harris Bank, N.A. The First Amendment modified the Credit Agreement, which had a maximum revolving credit line of $140,000 and provided for a $25,000 term loan of which $22,500 remained outstanding as of June 26, 2020. The First Amendment provides for a reduction in the revolving credit facility to permit aggregate borrowings of the Borrowers up to $120,000 with a sublimit of the equivalent of $25,000 U.S. dollars that is available to the Canadian and United Kingdom borrowers in the aggregate, and repaid and terminated the outstanding term loan by drawing funds on the revolving credit facility. The First Amendment provides additional $5,000 annual reductions to the revolving credit facility beginning on December 31, 2020 through the maturity of the facility on April 30, 2024.

Borrowings under the First Amendment bear interest at rates based upon either the base rate or Euro-rate plus applicable margins. The applicable margins have been adjusted as part of the First Amendment and are dictated by the ratio of the Company’s total net indebtedness to the Company’s consolidated earnings before interest, taxes, depreciation, and amortization (“Consolidated EBITDA”) for four trailing quarters, as defined in the Credit Agreement. The base rate is the highest of (a) the Overnight Bank Funding Rate plus 50 basis points, (b) the Prime Rate, or (c) the Daily Euro-rate plus 100 basis points (each as defined in the Credit Agreement) and an increase to the interest rate floor to 100 basis points. The base rate and Euro-rate spreads range from 100 to 200 basis points and 200 to 300 basis points, respectively.

The First Amendment further provides for modifications to the financial covenants as defined in the Credit Agreement. The First Amendment modified three financial covenants in the Credit Agreement: (a) Maximum Gross Leverage Ratio, defined as the

17

Company’s Consolidated Indebtedness divided by the Company’s Consolidated EBITDA, which must not exceed, other than during a period of four consecutive fiscal quarters of the Company beginning with a fiscal quarter during which the Company consummates a permitted acquisition, and including such fiscal quarter and the immediately three succeeding fiscal quarters (the “Acquisition Period”), (i) 3.25 to 1.00 for the testing period ended June 30, 2020, 3.00 to 1.00 for the testing periods ending September 30, 2020 through March 31, 2022, and 2.75 to 1.00 for the testing periods June 30, 2022 and thereafter, and (ii) 3.50 to 1.00 for the testing period ended June 30, 2020, 3.25 to 1.00 for the testing periods ending September 30, 2020 through March 31, 2022, and 3.00 to 1.00 for the testing periods ending June 30, 2022 and thereafter occurring during an Acquisition Period; (b) Minimum Consolidated Fixed Charge Coverage Ratio, defined as the Company's Consolidated EBITDA divided by the Company's Fixed Charges, which must be a minimum of 1.00 to 1.00 for the testing period ended June 30, 2020, 1.05 to 1.00 for the testing periods ending September 30, 2020 through June 30, 2021, 1.15 to 1.00 for the testing periods ending September 30, 2021 through June 30, 2022, and 1.25 to 1.00 for the testing periods ending September 30, 2022 and thereafter; and (c) Minimum Working Capital to Revolving Facility Usage Ratio, defined as the sum of 50% of the inventory and 85% of the accounts receivable of the Borrowers and certain other Guarantors divided by the dollar equivalent sum of the outstanding revolving credit loans, the outstanding swing loans, and the letter of credit obligations (the “Revolving Facility Usage”), which must not be less than 1.50 to 1.00. In addition, the First Amendment modifies the definition of Consolidated EBITDA to allow for certain additional adjustments. The First Amendment also includes changes to the non-financial covenants as defined in the Credit Agreement by increasing the basket for dispositions from $25,000 to $40,000. The Credit Agreement’s incremental loan feature permits the Company to increase the available revolving borrowings under the facility by up to an additional $50,000 subject to the Company’s receipt of increased commitments from existing or new lenders and the satisfaction of certain conditions.

The Company’s and the domestic, Canadian, and United Kingdom guarantors’ (the “Guarantors”) obligations under the Credit Agreement are secured by the grant of a security interest by the Borrowers and Guarantors in substantially all of the personal property owned by such entities. Additionally, the equity interests in each of the loan parties, other than the Company, and the equity interests held by each loan party in its respective domestic subsidiaries, have been pledged to the lenders as collateral for the lending obligations.

The Credit Agreement permits the Company to pay dividends and make distributions and redemptions with respect to its stock provided no event of default or potential default (as defined in the Credit Agreement) has occurred prior to or after giving effect to the dividend, distribution, or redemption. Additionally, the Credit Agreement permits the Company to complete acquisitions so long as (a) no event of default or potential default has occurred prior to or as a result of such acquisition; (b) the liquidity of the Borrowers is not less than $25,000 prior to and after giving effect to such acquisition; and (c) the aggregate consideration for the acquisition did not exceed: (i) $50,000 per acquisition; (ii) $50,000 in the aggregate for multiple acquisitions entered into during four consecutive quarters; and (iii) $100,000 in the aggregate over the term of the Credit Agreement.

Other restrictions exist at all times including, but not limited to, limitations on the Company’s sale of assets and the incurrence by either the Borrowers or the non-borrower subsidiaries of the Company of other indebtedness, guarantees, and liens.

As of September 30, 2020, the Company was in compliance with the covenants in the First Amendment.

As of September 30, 2020, the Company had outstanding letters of credit of approximately $1,043 and had net available borrowing capacity of $70,105. The maturity date of the facility is April 30, 2024.

Note 11. Fair Value Measurements

The Company determines the fair value of assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair values are based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations. The fair value hierarchy is based on whether the inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s own assumptions of what market participants would use. The fair value hierarchy includes three levels of inputs that may be used to measure fair value as described below:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

The classification of a financial asset or liability within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Cash equivalents - Included within “Cash and cash equivalents” in the Condensed Consolidated Balance Sheets are investments in non-domestic term deposits. The carrying amounts approximate fair value because of the short maturity of the instruments.

18

LIBOR-based interest rate swaps - To reduce the impact of interest rate changes on outstanding variable-rate debt, the Company entered into forward starting LIBOR-based interest rate swaps with notional values totaling $50,000. The fair value of the interest rate swaps is based on market-observable forward interest rates and represents the estimated amount that the Company would pay to terminate the agreements. As such, the swap agreements are classified as Level 2 within the fair value hierarchy. As of September 30, 2020 and December 31, 2019, the interest rate swaps were recorded within “Other accrued liabilities” in the Condensed Consolidated Balance Sheets.

	Fair Value Measurements at Reporting Date								Fair Value Measurements at Reporting Date
	September 30, 2020		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		December 31, 2019		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

The Company accounts for the interest rate swaps as cash flow hedges and the objective of the hedges is to offset the expected interest variability on payments associated with the interest rate on our debt. The Company de-designated its cash flow hedges and accounts for all existing and future interest rate swaps on a mark-to-market basis with changes in fair value recorded in current period earnings. In connection with this de-designation, the Company froze the balances recorded in “Accumulated other comprehesive loss” at June 30, 2020 and reclassifies balances to earnings as the underlying physical transactions occur, unless it is no longer probable that the physical transaction will occur at which time the related gains deferred in Other Comprehesive Income will be immediately recorded in earnings. The gains and losses related to the interest rate swaps are reclassified from “Accumulated other comprehensive loss” in the Condensed Consolidated Balance Sheets and included in “Interest expense - net” in the Condensed Consolidated Statements of Operations as the interest expense from our debt is recognized. For the three months ended September 30, 2020 and 2019, we recognized interest expense of $178 and interest income of $21, respectively, and for the nine months ended September 30, 2020 and 2019, we recognized interest expense of $468 and interest income of $142, respectively, from interest rate swaps.

The Company recognized interest income of $234 from the change in fair value of the interest rate swaps in “Interest expense - net” in the Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2020.

In accordance with the provisions of the FASB's Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurement,” the Company measures certain nonfinancial assets and liabilities at fair value, which are recognized and disclosed on a nonrecurring basis.

There were no anti-dilutive shares during the three and nine months ended September 30, 2020 and 2019.

Note 13. Stock-based Compensation

The Company applies the provisions of ASC 718, “Compensation – Stock Compensation,” to account for the Company’s stock-based compensation. Stock-based compensation cost is measured at the grant date based on the calculated fair value of the award and is recognized over the employees’ requisite service periods. The Company recorded stock compensation expense related to restricted stock awards and performance share units of $604 and $876 for the three months ended September 30, 2020 and 2019, respectively, and $1,842 and $2,910 for the nine months ended September 30, 2020 and 2019, respectively. As of September 30, 2020, unrecognized compensation expense for unvested awards approximated $4,096. The Company expects to recognize this expense over the upcoming 3.5 years through March 2024.

Shares issued as a result of vested stock-based compensation awards generally will be from previously issued shares that have been reacquired by the Company and held as treasury stock or authorized and previously unissued common stock.

Restricted Stock Awards and Performance Share Units

Under the 2006 Omnibus Plan, the Company grants eligible employees restricted stock and performance share units. The forfeitable restricted stock awards granted generally time-vest ratably over a three-year period, unless indicated otherwise by the underlying restricted stock agreement. Since May 2018, awards of restricted stock have been subject to a minimum one-year vesting period, including those granted to non-employee directors. Prior to May 2018, awards to non-employee directors were made in fully-vested shares. Performance share units are offered annually under separate three-year long-term incentive programs. Performance share units are subject to forfeiture and will be converted into common stock of the Company based upon the Company’s performance relative to performance measures and conversion multiples, as defined in the underlying program. If the Company’s estimate of the number of performance share units expected to vest changes in a subsequent accounting period, cumulative compensation expense could increase or decrease. The change will be recognized in the current period for the vested shares and would change future expense over the remaining vesting period.

Since May 1, 2017, non-employee directors have been permitted to defer receipt of annual stock awards and equity elected to be received in lieu of quarterly cash compensation. If so elected, these deferred stock units will be issued as common stock six months

20

after separation from their service on the Board of Directors. Since May 2018, no non-employee directors have elected the option to receive deferred stock units of the Company’s common stock in lieu of director cash compensation.

In February 2020, the Compensation Committee approved the 2020 Performance Share Unit Program and the Executive Annual Incentive Compensation Plan (consisting of cash and equity components).

The following table summarizes the restricted stock awards, deferred stock units, and performance share units activity for the nine months ended September 30, 2020:

	Restricted Stock	Deferred Stock Units	Performance Share Units	Weighted Average Grant Date Fair Value
Outstanding as of December 31, 2019	150,799	54,078	331,148	$	18.50

Note 14. Retirement Plans

Retirement Plans

The Company has three retirement plans that cover its hourly and salaried employees in the United States: one defined benefit plan, which is frozen, and two defined contribution plans. Employees are eligible to participate in the appropriate plan based on employment classification. The Company’s contributions to the defined benefit and defined contribution plans are governed by the Employee Retirement Income Security Act of 1974 (“ERISA”) and the Company’s policy and investment guidelines applicable to each respective plan. The Company’s policy is to contribute at least the minimum in accordance with the funding standards of ERISA.

The Company maintains two defined contribution plans for its employees in Canada, as well as one post-retirement benefit plan. The Company also maintains two defined contribution plans and one defined benefit plan for its employees in the United Kingdom.

Note 15. Commitments and Contingent Liabilities

Product Liability Claims

The Company is subject to product warranty claims that arise in the ordinary course of its business. For certain manufactured products, the Company maintains a product warranty accrual, which is adjusted on a monthly basis as a percentage of cost of sales. In addition, the product warranty accrual is adjusted periodically based on the identification or resolution of known individual product warranty claims.

The following table sets forth the Company’s product warranty accrual:

	Warranty Liability
Balance as of December 31, 2019	$	1,222
Additions to warranty liability	571
Warranty liability utilized	(607)
Balance as of September 30, 2020	$	1,186

Union Pacific Railroad (“UPRR”) Concrete Tie Matter

On March 13, 2019, the Company and its subsidiary, CXT Incorporated (“CXT”), entered into a Settlement Agreement (the “Settlement Agreement”) with UPRR to resolve the pending litigation in the matter of Union Pacific Railroad Company v. L.B. Foster Company and CXT Incorporated, Case No. CI 15-564, in the District Court for Douglas County, Nebraska.

Under the Settlement Agreement, the Company and CXT will pay UPRR the aggregate amount of $50,000 without pre-judgment interest, which began with a $2,000 immediate payment, and with the remaining $48,000 paid in installments over a six-year period commencing on the effective date of the Settlement Agreement through December 2024 pursuant to a Promissory Note. Additionally, commencing in January 2019 and through December 2024, UPRR agreed to purchase and has been purchasing from the Company and its subsidiaries and affiliates, a cumulative total amount of $48,000 of products and services, targeting $8,000 of annual purchases per year beginning March 13, 2019 per letters of intent under the Settlement Agreement. The Settlement Agreement also includes a mutual release of all claims and liability regarding or relating to all CXT pre-stressed concrete railroad ties with no admission of liability and dismissal of the litigation with prejudice.

The expected payments under the UPRR Settlement Agreement for the remainder of the year ending December 31, 2020 and thereafter are as follows:

Year Ending December 31,
Remainder of 2020	$	4,000
2021	8,000

Environmental and Legal Proceedings

The Company is subject to national, state, foreign, provincial, and/or local laws and regulations relating to the protection of the environment. The Company’s efforts to comply with environmental regulations may have an adverse effect on its future earnings.

On June 5, 2017, a General Notice Letter was received from the United States Environmental Protection Agency (“EPA”) indicating that the Company may be a potentially responsible party (“PRP”) regarding the Portland Harbor Superfund Site cleanup along with numerous other companies. More than 140 other companies received such a notice. The Company and a predecessor owned and operated a facility near the harbor site for a period prior to 1982. The net present value and undiscounted costs of the selected remedy throughout the harbor site are estimated by the EPA to be approximately $1.1 billion and $1.7 billion, respectively, and the remedial work is expected to take as long as 13 years to complete. The Company is reviewing the basis for its identification by the EPA and the nature of the historic operations of a Company predecessor near the site. Additionally, the Company executed a PRP agreement which provides for a private allocation process among almost 100 PRPs in a working group whose work is ongoing. On March 26, 2020, the EPA issued a Unilateral Administrative Order to two parties requiring them to perform remedial design work for that portion of the Harbor Superfund Site that includes the area closest to the facility; the Company was not a recipient of this Unilateral Administrative Order. We cannot predict the ultimate impact of these proceedings because of the large number of PRPs involved throughout the harbor site, the degree of contamination of various wastes, varying environmental impacts throughout the harbor site, the scarcity of data related to the facility once operated by the Company and a predecessor, and the speculative nature of the remediation costs. Based upon information currently available, management does not believe that the Company’s alleged PRP status regarding the Portland Harbor Superfund Site or other compliance with the present environmental protection laws will have a material adverse effect on the financial condition, results of operations, cash flows, competitive position, or capital expenditures of the Company.

As of September 30, 2020 and December 31, 2019, the Company maintained environmental reserves approximating $2,562 and $2,608, respectively. The following table sets forth the Company’s environmental obligation:

	Environmental liability
Balance as of December 31, 2019	$	2,608
Environmental obligations utilized	(46)
Balance as of September 30, 2020	$	2,562

The Company is also subject to other legal proceedings and claims that arise in the ordinary course of its business. Legal actions are subject to inherent uncertainties, and future events could change management's assessment of the probability or estimated amount of potential losses from pending or threatened legal actions. Based on available information, it is the opinion of management that the ultimate resolution of pending or threatened legal actions, both individually and in the aggregate, will not result in losses having a material adverse effect on the Company's financial position or liquidity as of September 30, 2020.

If management believes that, based on available information, it is at least reasonably possible that a material loss (or additional material loss in excess of any accrual) will be incurred in connection with any legal actions, the Company discloses an estimate of the possible loss or range of loss, either individually or in the aggregate, as appropriate, if such an estimate can be made, or discloses that an estimate cannot be made. Based on the Company's assessment as of September 30, 2020, no such disclosures were considered necessary.

Note 16. Income Taxes

For the three months ended September 30, 2020 and 2019, the Company recorded an income tax benefit of $13,742 on pre-tax income from continuing operations of $2,836 and an income tax expense of $836 on pre-tax income from continuing operations of $4,590, respectively, for effective income tax rates of (484.6)% and 18.2%, respectively. For the nine months ended September 30, 2020 and 2019, the Company recorded an income tax benefit of $11,698 on pre-tax income from continuing operations of $11,845 and an income tax expense of $3,883 on pre-tax income from continuing operations of $21,656, respectively, for effective income tax rates of (98.8)% and 17.9%, respectively. The Company’s income tax benefit from continuing operations for the three- and nine-month periods ended September 30, 2020 included a discrete income tax benefit of $15,824 related to the disposition of the Test and Inspection Services business. In addition to the impact of discrete items, the Company's effective tax rate for the nine months ended September 30, 2020 differed from the federal statutory rate of 21% primarily due to state income taxes, nondeductible expenses, and global intangible low-taxed income (“GILTI”) inclusions.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted in response to the COVID-19 pandemic. The CARES Act contains several corporate income tax provisions, including providing for a five-year carryback of net operating losses (“NOL”) generated in tax years 2018 through 2020, removing the 80% taxable income limitation on utilization of those NOLs if carried back to prior tax years or utilized in tax years beginning before 2021, making remaining alternative minimum tax (“AMT”) credits immediately refundable, and temporarily relaxing the interest deductibility rules by raising the adjusted taxable income limitation from 30% to 50% for tax years 2019 and 2020. As of September 30, 2020, the Company has recorded an income tax receivable of $9,008 to reflect expected tax refunds of federal taxes paid within the five year NOL carryback period.

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

(Dollars in thousands, except share data)

Forward-Looking Statements

This Quarterly Report on Form 10-Q contains “forward-looking” statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and Section 27A of the Securities Act of 1933, as amended. Many of the forward-looking statements are located in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (“MD&A”). Forward-looking statements provide management’s current expectations of future events based on certain assumptions and include any statement that does not directly relate to any historical or current fact. Sentences containing words such as “believe,” “intend,” “plan,” “may,” “expect,” “should,” “could,” “anticipate,” “estimate,” “predict,” “project,” or their negatives, or other similar expressions of a future or forward-looking nature generally should be considered forward-looking statements. Forward-looking statements in this Quarterly Report on Form 10-Q are based on management’s current expectations and assumptions about future events that involve inherent risks and uncertainties and may concern, among other things, the Company’s expectations relating to our strategy, goals, projections, and plans regarding our financial position, liquidity, capital resources, and results of operations and decisions regarding our strategic growth initiatives, market position, and product development. While the Company considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory, and other risks and uncertainties, most of which are difficult to predict and many of which are beyond the Company’s control. The Company cautions readers that various factors could cause the actual results of the Company to differ materially from those indicated by forward-looking statements. Accordingly, investors should not place undue reliance on forward-looking statements as a prediction of actual results. Among the factors that could cause the actual results to differ materially from those indicated in the forward-looking statements are risks and uncertainties related to: the COVID-19 pandemic, and any future global health crises, and the related social, regulatory, and economic impacts and the response thereto by the Company, our employees, our customers, and national, state, or local governments; a continued deterioration in the prices of oil and natural gas and the related impact on the upstream and midstream energy markets; a continuation or worsening of the adverse economic conditions in the markets we serve, whether as a result of the current COVID-19 pandemic, including its impact on travel and demand for oil and gas, and the continued deterioration in the prices for oil and gas, or otherwise; volatility in the global capital markets, including interest rate fluctuations, which could adversely affect our ability to access the capital markets on terms that are favorable to us; restrictions on our ability to draw on our credit agreement, including as a result of any future inability to comply with restrictive covenants contained therein; a continuing decrease in freight or transit rail traffic, including as a result of the COVID-19 pandemic; environmental matters, including any costs associated with any remediation and monitoring; the risk of doing business in international markets, including compliance with anti-corruption and bribery laws, foreign currency fluctuations and inflation, and trade restrictions or embargoes; our ability to effectuate our strategy, including cost reduction initiatives, and our ability to effectively integrate acquired businesses or to divest businesses, such as the recent disposition of the IOS Test and Inspection Services business and acquisition of LarKen Precast, LLC and to realize anticipated benefits; costs of and impacts associated with shareholder activism; continued customer restrictions regarding the on-site presence of third party providers due to the COVID-19 pandemic; the timeliness and availability of materials from our major suppliers, including any continuation or worsening of the disruptions in the supply chain experienced as a result of the COVID-19 pandemic, as well as the impact on our access to supplies of customer preferences as to the origin of such supplies, such as customers’ concerns about conflict minerals; labor disputes; cyber-security risks such as data security breaches, malware, ransomware, “hacking,” and identity theft, a failure of which could disrupt our business and may result in misuse or misappropriation of confidential or proprietary information, and could result in the disruption or damage to our systems, increased costs and losses, or an adverse effect to our reputation; the continuing effective implementation of an enterprise resource planning system; changes in current accounting estimates and their ultimate outcomes; the adequacy of internal and external sources of funds to meet financing needs, including our ability to negotiate any additional necessary amendments to our credit agreement or the terms of any new credit agreement, and reforms regarding the use of LIBOR as a benchmark for establishing applicable interest rates; the Company’s ability to manage its working capital requirements and indebtedness; domestic and international taxes, including estimates that may impact taxes; domestic and foreign government regulations, including tariffs; economic conditions and regulatory changes caused by the United Kingdom’s exit from the European Union; a lack of state or federal funding for new infrastructure projects; an increase in manufacturing or material costs; the loss of future revenues from current customers; and risks inherent in litigation and the outcome of litigation and product warranty claims. Should one or more of these risks or uncertainties materialize, or should the assumptions underlying the forward-looking statements prove incorrect, actual outcomes could vary materially from those indicated. Significant risks and uncertainties that may affect the operations, performance, and results of the Company’s business and forward-looking statements include, but are not limited to, those set forth under Item 1A, “Risk Factors,” and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2019, or as updated and amended by other current or periodic filings with the Securities and Exchange Commission.

The forward-looking statements in this report are made as of the date of this report and we assume no obligation to update or revise any forward-looking statement, whether as a result of new information, future developments, or otherwise, except as required by the federal securities laws.

L.B. Foster Company is a leading manufacturer and distributor of products and provider of services for transportation and energy infrastructure with locations in North America and Europe. The Company is comprised of three operating segments: Rail Products and Services, Construction Products, and Tubular and Energy Services.

Beginning in March 2020, in response to the COVID-19 pandemic, several national, state, provincial, and local state of emergency orders were declared that included significant restrictive measures in the countries and other jurisdictions in which the Company sells, manufactures, and services products and systems. The Company has been considered an “essential” business under the majority of these governmental orders and, as such, has been allowed to continue operating in such jurisdictions. In response, the Company adopted its Pandemic Action Plan, pursuant to which the Company implemented a range of enhanced safety protocols recommended by the United States (“U.S.”) Centers for Disease Control and Prevention and by applicable recommendations of non-U.S. governments and authorities in order to mitigate the spread of the virus while the Company continues operations in various locations.

As a result of the COVID-19 pandemic, the Company has experienced disruptions in supply chains, delays in deliveries to customers, and customer unwillingness to have the Company's employees work on site, as well as general weakness in demand as certain restrictions continued to be in place in most areas. Most notably, the collapse in oil demand associated with reduced travel resulting from the COVID-19 pandemic that led to a significant drop in demand for most of the services offered by our Tubular and Energy Services segment has persisted.

Despite some easing of initial restrictive measures, the Company anticipates continued disruptions in the fourth quarter of 2020 and beyond as various restrictive measures have remained in effect in the major markets we serve. The Company has experienced minimal disruption with its on-premise workforce in its facilities up to this point, and the Company expects to continue to operate under its pandemic protocols with minimal changes. The third quarter has historically been an important quarter for the Company, as it typically experiences a seasonal increase in sales as construction projects are at the height of their activity. However, sales for the third quarter of 2020 declined when compared to the prior year quarter. While sales declined in the current quarter, the Rail Products and Services and Construction Products segments reported increased order activity during the third quarter of 2020, as compared to the third quarter of 2019, despite the COVID-19 pandemic, and continue to experience steady proposal activity as of the date of the filing of this Quarterly Report on Form 10-Q. However, the outlook for the Tubular and Energy Services segment continues to remain much less favorable due to the more severe impact on demand that the COVID-19 pandemic has had in the energy markets.

The year-over-year increase in new orders for the three months ended September 30, 2020 of 8.3% and 6.6% in Construction Products and Rail Products and Services, respectively, led to backlog increases in the third quarter of 2020 of 36.6% for the Construction Products segment and 23.9% for the Rail Products and Services segment compared to the prior year period. This increase highlights the ongoing spending in the infrastructure markets served by these two segments despite pockets of weakness associated with traffic volume and transportation related projects due to the COVID-19 pandemic.

The Rail Products and Services segment is anticipating further recovery in Rail Technologies, particularly products and services related to its operations in the United Kingdom, barring any new COVID-19 restrictive measures. Transit based bookings were strong in the third quarter of 2020, including concrete ties for transit systems. As the Company monitors the budget shortfalls incurred by transit operators in all markets, projects associated with long term planning have been moving forward. However, the Company is not expecting a notable improvement in the sales of consumable products that are usually correlated to traffic volume through the remainder of 2020 and into 2021 given the on-going depressed travel volume driven by the COVID-19 pandemic, which the Company expects to continue.

The Construction Products segment backlog increase was driven by a steady quarter of order activity in the Piling and Fabricated Bridge division. This division saw key projects drive growth in the segment's backlog, as it increased sequentially from the second quarter of 2020. The backlog for bridge decking is expected to continue to result in production rates at near capacity levels. The Precast Concrete Products division continues to benefit from new infrastructure in the regions that the Company serves. While this business depends on municipal, state, and federal spending for certain programs that may experience budget pressures, these programs could benefit from continued government spending on infrastructure and economic stimulus efforts related to civil construction projects.

Since the middle of 2019, the upstream energy markets that the Company served has deteriorated as prices of oil and natural gas declined due to weakening demand. This deterioration has recently accelerated as a result of the global COVID-19 pandemic and the associated reduction in demand due to reduced travel and movement of goods throughout the world. As U.S. exploration and production companies have reduced production and implemented spending cuts, demand for much of the Company’s offerings in its IOS Test and Inspection Services business of the Tubular and Energy segment had sharply declined. As a result, on September 4, 2020, the Company completed the sale of the issued and outstanding membership interests of its upstream oil and gas test and

25

inspection business (“Test and Inspection Services”). Proceeds from the sale were $4,000 and resulted in a loss of $10,034, net of tax. As a result of the sale of this business, the Company recognized an aggregate of $18,962 in tax benefits, including tax benefits recognized in discontinued operations, for the three months ended September 30, 2020. In addition, the Company anticipates receiving approximately $9,008 in tax refunds within the next year due to extended carryback provisions in the CARES Act and the acceleration of existing deferred tax assets related to the sale. The sale represents a strategic shift away from providing services to the upstream oil and gas market. The Company believes that this divestiture also changes the risk profile of the Company by: (a) eliminating dependence on the upstream energy market and the liability associated with serving upstream applications; (b) reducing exposure to a volatile industry that can turnoff demand quickly under poor conditions; and (c) avoiding the price and production cyclicality of the global oil market. On a prospective basis, the Company’s tubular and energy businesses will continue to be focused on core competencies around corrosion protection and measurement systems in midstream pipeline applications, where the market has been much less volatile and tends to have longer term investments and associated backlog compared to upstream activities. The Company has reflected the results of operations of the Test and Inspection Services business as discontinued operations in the Condensed Consolidated Financial Statements and recast the Tubular and Energy Services segment results for all periods presented.

In the Tubular and Energy Services segment, the severe decline in travel due to the COVID-19 pandemic has led to significant reductions in the production of oil as demand for fuel has declined by record amounts. On a year-to-date basis for 2020, sales have declined 29.4% and orders have declined by 50.8% in the Tubular and Energy segment. As a result of the significant decline in order activity, backlog is down substantially compared to September 30, 2019 and December 31, 2019. This has led to the Company projecting material declines in sales for this segment for the remainder of 2020 and into 2021. As a result of these projections, the Company is continuing to take actions to align the costs associated with this segment to the projected revenue streams. The served midstream energy market has longer-term projects associated with it, and certain of these projects are expected to continue based on projected needs once the market returns to a more historically normalized volume level.

Third Quarter 2020 Compared to Third Quarter 2019 – Company Analysis

Net sales of $118,365 for the three months ended September 30, 2020 decreased by $26,483, or 18.3%, compared to the prior year quarter. The decline was attributable to reductions within each of the three segments, due in part to disruptions across each of the segments caused by the COVID-19 pandemic. Sales for the Tubular and Energy Services segment decreased by 44.9%, the Construction Products segment decreased by 19.7%, and the Rail Products and Services segment decreased by 5.5%.

Gross profit decreased by $5,890 compared to the prior year quarter to $22,061 for the three months ended September 30, 2020. The decline in gross profit was attributable to each of the three segments, as Tubular and Energy Services decreased by 55.6%, Rail Products and Services decreased by 10.5%, and Construction Products decreased by 4.4%. Gross profit margin for the three months ended September 30, 2020 was 18.6%, or 70 basis points (“bps”) lower than the prior year quarter, primarily due to Tubular and Energy Services.

Selling and administrative expenses decreased by $3,969, or 18.9%, compared to the prior year quarter. The decrease in expense was primarily driven by reductions in personnel related expenses of $2,693 and third-party professional service expenses of $592, primarily as a result of cost containment measures across all segments. As a percent of sales, selling and administrative expenses decreased 10 bps compared to the prior year quarter, despite the 18.3% reduction in sales.

The Company’s effective income tax rate for the three months ended September 30, 2020 was (484.6)%, compared to 18.2% in the prior year quarter. For the three months ended September 30, 2020, the Company recorded an income tax benefit of $13,742,

27

compared to income tax expense of $836 in the three months ended September 30, 2019. The Company’s provision for income taxes for the three months ended September 30, 2020 included a discrete income tax benefit of $15,824 related to the disposition of the Test and Inspection Services business. In addition to the impact of the discrete item, the effective tax rate for the quarter ended September 30, 2020 differed from the federal statutory rate of 21% primarily due to state income taxes, nondeductible expenses, and GILTI inclusions.

Net income from continuing operations for the third quarter of 2020 was $16,578, or $1.56 per diluted share, compared to $3,754, or $0.35 per diluted share, in the prior year quarter.

Third Quarter 2020 Compared to Third Quarter 2019

The Rail Products and Services segment sales for the three months ended September 30, 2020 decreased by $3,753, or 5.5%, compared to the prior year quarter. The sales decline was primarily driven by the Rail Technologies business unit, which decreased by $2,586, or 9.1%, due primarily to reduced sales of our North American friction management consumable products and services as freight and transit rail customer traffic declined due to the COVID-19 pandemic and also reduced activity levels on the London Crossrail project in the U.K., primarily from a work stoppage due to stay-at-home orders resulting from the COVID-19 pandemic. On-site services for the London Crossrail project resumed during the third quarter of 2020. Also contributing to the sales decline was the Rail Products business, which decreased by $1,167, or 3.0%, from the prior year, primarily related to the decline in freight and passenger traffic resulting in infrastructure spending reductions impacting the segment’s offerings.

The Rail Products and Services segment gross profit decreased by $1,523, or 10.5%, from the prior year quarter. The decrease was primarily driven by the volume decline in the Rail Technologies business. Segment gross profit margin decreased by 120 bps as a result of the reduced sales volume. Segment profit was $3,742, a $325 increase over the prior year quarter. Selling and administrative expenses incurred by the segment decreased by $1,804 compared to the prior year quarter, primarily attributable to decreased personnel related costs and third-party professional service costs, as cost containment remained a key focus given the challenging market conditions.

During the current quarter, the Rail Products and Services segment had an increase in new orders of 6.6% compared to the prior year period. The increase was primarily related to activity within our North American transit market, including new rail and concrete tie products.

Third Quarter 2020 Compared to Third Quarter 2019

The Construction Products segment sales for the three months ended September 30, 2020 decreased by $9,292, or 19.7%, compared to the prior year quarter. The decline was attributable to volume decreases in both the Piling and Fabricated Bridge division and the Precast Concrete Products division, resulting in sales reductions of $6,565 and $2,727, respectively. Piling and Fabricated Bridge experienced a decline in volume during the current year quarter primarily due to the completion of the Port Everglades project in the

28

fourth quarter of 2019. The Precast Concrete Products business unit sales were unfavorably impacted by installation delays of precast concrete buildings caused by inclement weather conditions, as well as wildfires effecting the western U.S.

Construction Products gross profit decreased by $267, or 4.4%, over the prior year quarter. The decrease was attributable to lower sales volume in the Precast Concrete Products division. Gross profit margin for the third quarter of 2020 increased by 250 bps compared to the prior year quarter, which was a result of margin improvements within Piling Products as project overage costs negatively impacted the prior year quarter. The segment profit of $1,756 was a reduction of $92 from the prior year quarter segment profit of $1,848.

During the quarter, the Construction Products segment had an increase in new orders of 8.3% compared to the prior year quarter, which was primarily related to Piling and Fabricated Bridge products. The Company believes that while order activity continues to be steady, the various restrictive measures enacted associated with COVID-19 are causing delays in the progress of scheduled projects. As of September 30, 2020, backlog for the Construction Products segment was $118,368, a 10.8% increase from June 30, 2020.

Tubular and Energy Services

On September 4, 2020, the Company sold its upstream oil and gas test and inspection business. Proceeds from the sale were $4,000 and resulted in a loss of $10,034, net of tax. The sale represents a strategic shift away from providing services to the upstream oil and gas market. We believe that this divestiture also changes the risk profile of the Company by (a) eliminating dependence on the upstream energy market and the liability associated with serving upstream applications; (b) reducing exposure to a volatile industry that can turnoff demand quickly under poor conditions; and (c) avoiding the price and production cyclicality of the global oil market. On a prospective basis, the Company’s tubular and energy businesses will continue to be focused on core competencies around corrosion protection and measurement systems in midstream pipeline applications, where the market has been much less volatile and tends to have longer term investments and associated backlog compared to upstream activities. We have reflected the results of operations of the Test and Inspection Services business as discontinued operations in the Condensed Consolidated Financial Statements and recast the segment results for all periods presented.

Third Quarter 2020 Compared to Third Quarter 2019

Tubular and Energy Services segment sales for the three months ended September 30, 2020 decreased by $13,438, or 44.9%, compared to the prior year quarter. The decrease was due to the deteriorated conditions in the served U.S. oil and gas market. The reduction in demand caused by reduced travel throughout the world as a result of the COVID-19 pandemic has caused exploration and production companies to further decrease their activities and reduce spending, which adversely impacted the need for our products and services offered by the segment. This led to a sales decrease of $14,141 in the Protective Coatings and Measurement Systems division.

Tubular and Energy Services segment gross profit decreased by $4,100, or 55.6%, which was primarily attributable to the reduced volumes within Protective Coatings and Measurement Systems. Segment gross profit margin decreased by 480 bps from the prior year quarter, primarily driven by reduced revenue volume. The segment profit decreased by $3,086, or 83.3%, from the prior year quarter.

The Tubular and Energy Services segment had a decrease of 50.7% in new orders compared to the prior year quarter. Each of the business units within the segment contributed to the decline in new orders, as capital spending and project delays within the served domestic oil and gas market negatively impacted the segment.

First Nine Months 2020 Compared to First Nine Months 2019

The Rail Products and Services segment sales for the nine months ended September 30, 2020 decreased by $35,705, or 14.6%, compared to the prior year period. The sales decline was driven by our Rail Products business which declined by $19,595, or 12.8%, and our Rail Technologies business which decreased by $16,110, or 17.6%, from the prior year. The decreases were due primarily to our North American transit projects and friction management consumable products and services, as freight and transit rail customer traffic declined as a result of the impact of the COVID-19 pandemic. Also contributing to the decline was reduced activity levels on the London Crossrail project in the U.K, primarily from the project nearing its completion and a temporary work stoppage due to stay-at-home orders resulting from the COVID-19 pandemic.

The Rail Products and Services segment gross profit decreased by $7,177, or 15.1%, from the prior year period. The decrease was primarily driven by the volume decline in the Rail Technologies business and, to a lesser extent, North American transit projects impacting the Rail Products business. Segment gross profit margin decreased by 10 bps as a result of reduced sales volume and was partially offset by favorable product mix of higher margin offerings within the Rail Products business. Segment profit was $10,729, a $4,086 decline from the prior year period.

During the nine months ended September 30, 2020, the Rail Products and Services segment had a decrease in new orders of 9.7% compared to the prior year period. The decrease was primarily related to reduced order activity related to global transit projects, friction management consumables, and on-track services. Backlog as of September 30, 2020 was $109,059, a 5.2% increase from December 31, 2019.

First Nine Months 2020 Compared to First Nine Months 2019

The Construction Products segment sales for the nine months ended September 30, 2020 decreased by $31,001, or 22.2%, compared to the prior year period. The decline was attributable to volume decreases in both the Piling and Fabricated Bridge division and the Precast Concrete Products division, resulting in sales reductions of $23,914 and $7,087, respectively. Piling and Fabricated Bridge

31

experienced decreased volume compared to the prior year period due to the significant activity level on the Port Everglades piling project in the prior year period without a project of comparable size during the nine months ended September 30, 2020. Our Precast Concrete Products business unit sales were unfavorably impacted by the relocation of operations to Boise, ID during the first half of 2020. This relocation resulted in the expected downtime of production until the new facility achieved full operational efficiency.

Construction Products gross profit decreased by $3,600, or 18.4%, from the prior year period. The decrease was primarily attributable to start-up activities resulting in reduced operational efficiency during the ramp-up of the new precast concrete facility in Boise, ID. The segment profit of $1,623 was a reduction of $4,472 from the prior year period segment profit of $6,095. Included within the first nine months of 2020 segment profit are relocation costs of $674 related to the Boise, ID facility.

During the nine months ended September 30, 2020, the Construction Products segment had new orders that increased by 2.4% when compared to the prior year period. The Company believes that the stay-at-home orders associated with COVID-19 have delayed the progress of scheduled projects. As of September 30, 2020, backlog was $118,368, a 28.3% increase from December 31, 2019.

First Nine Months 2020 Compared to First Nine Months 2019

Tubular and Energy Services segment sales decreased by $26,556, or 29.4%, compared to the prior year period. The decrease was due to deteriorating conditions in the served U.S. oil and gas market. The reduction in demand caused by reduced travel throughout the world as a result of the COVID-19 pandemic has caused exploration and production companies to decrease their activities and reduce spending, which impacted the need for our products and services within the segment. This led to a sales decrease of $27,190 from the prior year period in the Protective Coatings and Measurement Systems division, which primarily serves the midstream market.

Tubular and Energy Services segment gross profit decreased by $8,642, or 33.9%, which was primarily attributable to the reduced volumes within the Protective Coatings and Measurement Systems division. Segment gross profit margin decreased by 180 bps from the prior year period, which was primarily driven by reduced revenue volume. The segment profit decreased by $7,688, or 51.6%, from the prior year period to $7,213.

The Tubular and Energy Services segment had a decrease of 50.8% in new orders compared to the prior year period. Each of the business units within the segment contributed to the decline in new orders as capital spending and project delays within the served domestic oil and gas market negatively impacted the segment.

Other

Segment Backlog

Total Company backlog is summarized by business segment in the following table for the periods indicated:

	September 30, 2020		December 31, 2019		September 30, 2019
Rail Products and Services	$	109,059	$	103,694	$	88,051
Construction Products	118,368		92,280		86,626
Tubular and Energy Services	7,763		33,058		18,553
Total backlog	$	235,190	$	229,032	$	193,230

The Company’s backlog represents the sales price of received customer purchase orders and any contracts in which the performance obligations have not been met, and therefore are precluded from revenue recognition. Although the Company believes that the orders included in backlog are firm, customers may cancel or change their orders with limited advance notice; however, these instances have been rare. Backlog should not be considered a reliable indicator of the Company’s ability to achieve any particular level of revenue or financial performance. While a considerable portion of our business is backlog-driven, certain product lines within the Rail Products and Services and Tubular and Energy Services segments are not driven by backlog.

Liquidity and Capital Resources

Our principal sources of liquidity are our existing cash and cash equivalents, cash generated by operations, and the available capacity under our revolving credit facility, which provides for a total commitment of up to $120,000. Our primary needs for liquidity relate to working capital requirements for operations, capital expenditures, debt service obligations, and payments related to the Union Pacific Railroad Settlement. Our total debt was $49,104 and $58,152 as of September 30, 2020 and December 31, 2019, respectively, and was primarily comprised of borrowings under our revolving credit facility.

The following table reflects our available funding capacity as of September 30, 2020:

	September 30, 2020
Cash and cash equivalents		$	9,311
Credit agreement:
Total availability under the credit agreement	120,000
Outstanding borrowings on revolving credit facility	(48,852)
Letters of credit outstanding	(1,043)
Net availability under the revolving credit facility		70,105
Total available funding capacity		$	79,416

Our cash flows are impacted from period to period by fluctuations in working capital. While we place an emphasis on working capital management in our operations, factors such as our contract mix, commercial terms, days sales outstanding (“DSO”), and market conditions as well as seasonality may impact our working capital. We regularly assess our receivables for collectability, and provide allowances for doubtful accounts where appropriate. We believe that our reserves for doubtful accounts are appropriate as of September 30, 2020, but adverse changes in the economic environment, including further deterioration of demand for crude oil and natural gas in the energy markets, and adverse financial conditions of our customers resulting from, among other things, the COVID-19 pandemic, may impact certain of our customers’ ability to access capital and compensate us for our products and services, as well as impact demand for our products and services.

The changes in cash and cash equivalents for the nine months ended September 30, 2020 and 2019 were as follows:

	Nine Months Ended September 30,
	2020		2019
Net cash provided by continuing operating activities	$	16,201	$	10,311
Net cash used in continuing investing activities	(8,688)		(2,478)
Net cash used in continuing financing activities	(11,147)		(3,384)
Effect of exchange rate changes on cash and cash equivalents	(571)		12
Net cash (used) provided by discontinued operations	(662)		631
Net (decrease) increase in cash and cash equivalents	$	(4,867)	$	5,092

Cash Flow from Operating Activities

During the nine months ended September 30, 2020, cash flows provided by continuing operating activities were $16,201, compared $10,311 during the prior year to date period. For the nine months ended September 30, 2020, the net income from continuing operations and adjustments to net income from continuing operating activities provided $26,841, compared to $32,562 in the 2019 period. Working capital and other assets and liabilities used $10,640 in the current period, compared to $22,251 in the prior year period. During the nine months ended September 30, 2020 and 2019, the Company made payments totaling $4,000 and $6,000, respectively, under the terms of the concrete tie settlement agreement with Union Pacific Railroad. During the nine months ended September 30, 2020, the Company received a non-recurring disbursement of $1,874 from an unconsolidated partnership.

The Company’s calculation for DSO at September 30, 2020 and December 31, 2019 was 50 and 49 days, respectively, and we believe our receivables portfolio is strong.

Cash Flow from Investing Activities

Capital expenditures for the nine months ended September 30, 2020 and 2019 were $7,650 and $2,510, respectively. The current year expenditures include the purchase of a continuous welded rail car and unloader within our Rail Products and Services segment, facility start-up expenditures within our Construction Products segment, and general plant and operational improvements throughout the Company. Expenditures for the nine months ended September 30, 2019 related to plant expansion within our Tubular and Energy Services segment as well as general plant and operational improvements throughout the Company. Cash flows from investing

33

activities also includes $1,050 paid for the asset acquisition of a company in Boise, Idaho to expand our precast concrete offerings in that region.

Cash Flow from Financing Activities

During the nine months ended September 30, 2020, the Company had a reduction in outstanding debt of $9,033, primarily attributable to the utilization of excess cash generated through operating activities. During the nine months ended September 30, 2019, the Company had a decrease in outstanding debt of $1,948, primarily related to the reduction of working capital for operations. Treasury stock acquisitions of $1,660 and $600 for the nine months ended September 30, 2020 and 2019, respectively, represent income tax withholdings from employees and non-employee directors in connection with the vesting of restricted stock awards. During the nine months ended September 30, 2020 and 2019, the Company incurred debt issuance costs of $454 and $836, respectively.

Financial Condition

As of September 30, 2020, we had $9,311 in cash and cash equivalents. Our cash management priority continues to be short-term maturities and the preservation of our principal balances. As of September 30, 2020, approximately $8,386 of our cash and cash equivalents was held in non-domestic bank accounts. During the nine months ended September 30, 2020, the Company repatriated $5,387 in excess cash from our international locations. We principally maintain our cash and cash equivalents in accounts held by major banks and financial institutions.

Our principal uses of cash in recent years have been to fund our operations, including capital expenditures, and to service our indebtedness. We view our short and long-term liquidity as being dependent on our results of operations, changes in working capital and our borrowing capacity. As of September 30, 2020, our revolving credit facility had $70,105 of net availability, while we had $49,104 in total debt. Our current ratio as of September 30, 2020 was 2.05.

On June 26, 2020, we entered into the First Amendment that reduced the total commitments under the revolving credit facility to $120,000 from $140,000. The First Amendment requires additional $5,000 annual reductions to the revolving credit facility capacity beginning on December 31, 2020 through the maturity of the facility. In addition, the First Amendment terminated the existing term loan by drawing on the revolving credit facility. Borrowings under the First Amendment continue to bear interest rates based upon either the base rate or Euro-rate plus applicable margins. However, the First Amendment increased the applicable margins on the interest rates, and implemented an interest rate floor of 100 basis points. The First Amendment also modified the covenants associated with the credit agreement. We believe that the combination of our cash and cash equivalents, cash generated from operations and the capacity under our revolving credit facility will provide us with sufficient liquidity to provide the flexibility to operate the business in a prudent manner and enable us to continue to service our outstanding debt. For a discussion of the terms and availability of our credit facilities, please refer to Note 10 of the Notes to Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q.

To reduce the impact of interest rate changes on outstanding variable-rate debt, we entered into forward starting LIBOR-based interest rate swaps with notional values totaling $50,000. The swaps became effective on February 28, 2017, at which point they effectively converted a portion of the debt from variable to fixed-rate borrowings during the term of the swap contract. As of September 30, 2020 and December 31, 2019, the swap liability was $1,332 and $480, respectively.

On September 4, 2020, the Company sold its membership interests in the Test and Inspection Services business for gross proceeds of $4,000. As a result of this divestiture, the Company has reclassified the results of this business into discontinued operations. Due to the sale of this business, the Company recognized approximately $18,962 in tax benefits, including tax benefits recognized in discontinued operations, for the three and nine months ended September 30, 2020. In addition, the Company anticipates receiving approximately $9,008 in tax refunds within the next year due to extended carryback provisions in the CARES Act and the acceleration of existing deferred tax assets related to the sale. For additional information regarding the Test and Inspection Services sale, please refer to Note 3 of the Notes to Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q.

Critical Accounting Policies

The Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States. When more than one accounting principle, or method of its application, is generally accepted, management selects the principle or method that, in its opinion, is appropriate in the Company’s specific circumstances. Application of these accounting principles requires management to reach opinions regarding estimates about the future resolution of existing uncertainties. As a result, actual results could differ from these estimates. In preparing these financial statements, management has reached its opinions regarding the best estimates and judgments of the amounts and disclosures included in the financial statements giving due regard to materiality. We have updated our allowance for doubtful accounts policies since December 31, 2019, in conjunction with our adoption of Accounting Standards Codification Topic 326, “Financial Instruments - Credit Losses” (“ASC 326”), as further described in Note 6 and Note 7 of the Notes to Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q. A summary of the Company’s critical accounting policies and estimates is included in Item 7. Management’s Discussion and Analysis of

34

Financial Condition and Results of Operations - Critical Accounting Policies and Estimates in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Off-Balance Sheet Arrangements

The Company’s off-balance sheet arrangements include purchase obligations and standby letters of credit. A schedule of the Company’s required payments under financial instruments and other commitments as of December 31, 2019 is included in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources - Tabular Disclosure of Contractual Obligations in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. There were no material changes to these off-balance sheet arrangements during the current quarter. These arrangements provide the Company with increased flexibility relative to the utilization and investment of cash resources.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

The Company is exposed to risks that increases in interest rates may adversely affect funding costs associated with its variable-rate debt. To reduce the impact of interest rate changes on a portion of this variable-rate debt, the Company entered into forward starting interest rate swap agreements which effectively converted a portion of the debt from a variable to a fixed-rate borrowing during the term of the swap contracts. See Note 11 Fair Value Measurements of the Notes to Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q for additional information.

For the nine months ended September 30, 2020, a 1% change in the interest rate for variable rate debt as of September 30, 2020 would increase or decrease interest expense by approximately $753.

The Company does not purchase or hold any derivative financial instruments for trading purposes. It does enter into interest rate hedges to reduce the risk in the variability of interest rate fluctuations. At contract inception, the Company designates its derivative instruments as hedges. The Company recognizes all derivative instruments on the balance sheet at fair value. Fluctuations in the fair values of derivative instruments designated as cash flow hedges are recorded in “Accumulated other comprehensive loss” and reclassified into earnings within “Interest expense - net” as the underlying hedged items affect earnings. To the extent that a change in a derivative does not perfectly offset the change in value of the interest rate being hedged, the ineffective portion is recognized in earnings immediately.

As of September 30, 2020 and December 31, 2019, the Company recorded a current liability of $1,332 and $480, respectively, related to its LIBOR-based interest rate swap agreements.

Foreign Currency Exchange Rate Risk

The Company is subject to exposures to changes in foreign currency exchange rates. The Company may manage its exposure to changes in foreign currency exchange rates on firm sale and purchase commitments by entering into foreign currency forward contracts. The Company’s risk management objective is to reduce its exposure to the effects of changes in exchange rates on these transactions over the duration of the transactions. The Company did not engage in foreign currency hedging transactions during the nine months ended September 30, 2020.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

L.B. Foster Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and the Principal Accounting Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of September 30, 2020. Based upon that evaluation, the Chief Executive Officer and Principal Accounting Officer concluded that the Company’s disclosure controls and procedures were effective as of such date such that the information required to be disclosed by the Company in reports filed under the Exchange Act is (i) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to management, including the chief executive officer, chief financial officer, or person performing such functions, as appropriate to allow timely decisions regarding disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes to our “internal control over financial reporting” (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the nine months ended September 30, 2020, and that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

35

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating disclosure controls and procedures and internal control over financial reporting, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures and internal control over financial reporting must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Financial Statements

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all estimates and adjustments (consisting of normal recurring accruals, unless otherwise stated herein) considered necessary for a fair presentation of the financial position of L.B. Foster Company and subsidiaries as of September 30, 2020 and December 31, 2019, its Condensed Consolidated Statements of Operations, Condensed Consolidated Statements of Comprehensive Income, and its Condensed Consolidated Statements of Stockholders' Equity for the three and nine months ended September 30, 2020 and 2019, and its Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2020 and 2019, have been included. However, actual results could differ from those estimates. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. The Condensed Consolidated Balance Sheet as of December 31, 2019 was derived from audited financial statements. This Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and footnotes thereto included in L.B. Foster Company’s Annual Report on Form 10-K for the year ended December 31, 2019. In this Quarterly Report on Form 10-Q, references to “we,” “us,” “our,” and the “Company” refer collectively to L.B. Foster Company and its consolidated subsidiaries.

Recently Issued Accounting Standards

In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. (“ASU”) 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”), which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022. We are currently evaluating the impacts of the provisions of ASU 2020-04 on our financial condition, results of operations, and cash flows.

Recently Adopted Accounting Standards

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 added a new impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses and presents financial assets measured at amortized cost basis at the net amount expected to be collected upon inception. The CECL model applies to trade receivables, other receivables, and most debt instruments. The CECL model does not have a minimum threshold for recognition of impairment losses, and entities must measure expected credit losses on assets that have a low risk of loss. The Company adopted the provisions of ASU 2016-13 on January 1, 2020, using the modified retrospective approach as of the beginning of the period of adoption. In accordance with the standard, the Company evaluated its allowance for credit losses for trade receivables and contract assets, the only assets held by the Company that were impacted by the scope of the standard. The adoption of ASU 2016-13 had no material effect on the Company’s financial position or results of operations, and no adjustment to January 1, 2020 Retained earnings was recorded. The Company has presented the disclosures required by this new standard in Note 6 Accounts Receivable and Note 7 Inventory.

In August 2018, the FASB issued ASU 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software” (“ASU 2018-15”). ASU 2018-15 requires capitalization of certain implementation costs incurred in a cloud computing arrangement that qualifies as a service contract. The amendments in ASU 2018-15 are effective for fiscal years beginning after December 15, 2019 and for interim periods therein with early adoption permitted. The adoption of ASU 2018-15 had no impact on the Company’s consolidated financial statements and related disclosures.

Segment Reporting [Abstract]

Business Segments

Business Segments The Company is a leading manufacturer and distributor of products and provider of services for transportation and energy infrastructure with locations in North America and Europe. The Company's segments represent components of the Company (a) that engage in activities from which revenue is generated and expenses are incurred; (b) whose operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”), who uses such information to make decisions about resources to be allocated to the segments, and (c) for which discrete financial information is available. Operating segments are evaluated on their segment profit contribution to the Company's consolidated results. Other income and expenses, interest, income taxes, and certain other items are managed on a consolidated basis. The Company's segment accounting policies are the same as those described in Note 2. Business Segments of the Notes to the Company's Consolidated Financial Statements contained in its Annual Report on Form 10-K for the year-ended December 31, 2019.

The following table illustrates the Company's revenues and profit from operations by segment for the periods indicated:

	Three Months Ended September 30, 2020				Three Months Ended September 30, 2019

Total	$	381,835	$	19,565	$	475,097	$	35,811

Segment profit from operations, as shown above, includes allocated corporate operating expenses. Operating expenses related to corporate headquarter functions that directly support the segment activity are allocated based on segment headcount, revenue contribution, or activity of the business units within the segments, based on the corporate activity type provided to the segment. The expense allocation excludes certain corporate costs that are separately managed from the segments.

The following table provides a reconciliation of segment net profit from continuing operations to the Company’s consolidated continuing operations total for the periods presented:

Discontinued Operations and Disposal Groups [Abstract]

Discontinued Operations

Discontinued OperationsSince the middle of 2019, the upstream energy markets that the Company served has deteriorated as prices of oil and natural gas declined due to weakening demand. This deterioration has recently accelerated as a result of the global COVID-19 pandemic and the associated reduction in demand due to reduced travel and movement of goods throughout the world. As U.S. exploration and production companies have reduced production and implemented spending cuts, demand for much of the Company’s offerings in its IOS Test and Inspection Services business had sharply declined. As a result, on September 4, 2020, the Company completed the sale of the issued and outstanding membership interests of its upstream oil and gas test and inspection business, IOS Acquisitions, LLC and subsidiaries (“Test and Inspection Services”). Proceeds from the sale were $4,000 and resulted in a loss of $10,034, net of tax. We have reflected the results of operations of the Test and Inspection Services business as discontinued operations in the Condensed Consolidated Financial Statements for all periods presented. The Test and Inspection Services business was historically included in the Tubular and Energy Services business segment.

The following table provides the net sales and losses from discontinued operations for the periods presented:

	Three Months Ended September 30,				Nine Months Ended September 30,

Revenue from Contract with Customer [Abstract]

Revenue

RevenueRevenue from products or services provided to customers over time accounted for 32.2% and 35.6% of revenue for the three months ended September 30, 2020 and 2019, respectively, and 27.9% and 29.9% of revenue for the nine months ended September 30, 2020 and 2019, respectively. Revenue under these long-term agreements is generally recognized over time either using an input measure based upon the proportion of actual costs incurred to estimated total project costs or an input measure based upon actual labor costs as a percentage of estimated total labor costs, depending upon which measure the Company believes best depicts the Company’s performance to date under the terms of the contract. Revenue recognized over time using an input measure was $27,316 and $37,488 for the three months ended September 30, 2020 and 2019, respectively, and $76,606 and $104,309 for the nine months ended

September 30, 2020 and 2019, respectively. A certain portion of the Company’s revenue recognized over time under these long-term agreements is recognized using an output method, specifically units delivered, based upon certain customer acceptance and delivery requirements. Revenue recognized over time using an output measure was $10,800 and $14,031 for the three months ended September 30, 2020 and 2019, respectively, and $29,833 and $37,553 for the nine months ended September 30, 2020 and 2019, respectively. As of September 30, 2020 and December 31, 2019, the Company had contract assets of $36,891 and $37,032, respectively, that were recorded in “Inventories - net” within the Condensed Consolidated Balance Sheets. As of September 30, 2020 and December 31, 2019, the Company had contract liabilities of $3,606 and $4,472, respectively, that were recorded in “Deferred revenue” within the Condensed Consolidated Balance Sheets.

The majority of the Company’s revenue is from products transferred and services rendered to customers at a point in time. Point in time revenue accounted for 67.8% and 64.4% of revenue for the three months ended September 30, 2020 and 2019, respectively, and 72.1% and 70.1% of revenue for the nine months ended September 30, 2020 and 2019, respectively. The Company recognizes revenue at the point in time at which the customer obtains control of the product or service, which is generally when the product title passes to the customer upon shipment or the service has been rendered to the customer. In limited cases, title does not transfer and revenue is not recognized until the customer has received the products at a physical location.

The Company performs goodwill impairment tests annually during the fourth quarter, and also performs interim goodwill impairment tests if it is determined that it is more likely than not that the fair value of a reporting unit is less than the carrying amount. Qualitative factors are assessed to determine whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount, which included the impacts of COVID-19. However, the future impacts of COVID-19 are unpredictable and are subject to change. No interim goodwill impairment test was required as a result of the evaluation of qualitative factors as of September 30, 2020.

Accounts Receivable Additional Disclosures [Abstract]

Accounts Receivable

Accounts Receivable

The Company extends credit based upon an evaluation of the customer’s financial condition and, while collateral is not required, the Company periodically receives surety bonds that guarantee payment. Credit terms are consistent with industry standards and practices. The amounts of trade accounts receivable as of September 30, 2020 and December 31, 2019 have been reduced by an allowance for doubtful accounts of $1,176 and $1,073, respectively. Changes in reserves for uncollectable accounts, which are recorded as part of “Selling and administrative expenses” in the Condensed Consolidated Statements of Operations, resulted in income of $63 and $119 for the three months ended September 30, 2020 and 2019, respectively, and expense of $221 and income of $34 for the nine months ended September 30, 2020 and 2019, respectively.

On January 1, 2020, the Company adopted ASU 2016-13 and all the related amendments using the modified retrospective approach, which did not result in any changes to the previously reported financial information. The updates related to ASU 2016-13 were applied to assets held as of January 1, 2020.

In accordance with adoption of the new standard, the Company evaluated and revised its policies surrounding the allowance for credit losses for trade receivables. The Company established the allowance for credit losses by calculating the amount to reserve based on

the age of a given trade receivable and considering historical collection patterns and bad debt expense experience, in addition to any other relevant subjective adjustments to individual receivables made by management. The Company also considered current and expected future market and other conditions. Trade receivables are pooled within the calculation based on a range of ages, which appropriately groups receivables of similar credit risk together.

The established reserve thresholds to calculate the allowance for credit loss are based on and supported by historic collection patterns and bad debt expense incurred by the Company, as well as the expectation that collection patterns and bad debt expense will continue to adhere to patterns observed in recent years, which was formed based on trends observed as well as current and expected future conditions. Management maintains high-quality credit review practices as well as positive customer relationships that further mitigate credit risk. Management monitors and reviews the contributing factors to our reserve, and makes any appropriate revisions as they become necessary.

The Company’s adoption of ASU 2016-13 did not require material changes to the allowance for credit losses and no adjustment was recorded to opening retained earnings as of January 1, 2020.

Inventories - net	$	117,267	$	118,461

Inventories of the Company are valued at average cost or net realizable value, whichever is lower.

In accordance with adoption of ASU 2016-13, the Company evaluated and revised its policies relating to the allowance for credit losses as they pertain to contract assets, as these assets held in inventory will convert to trade receivables upon recognition of revenue for the contract to which they pertain.

In addition to contract-specific provisions for which reserves were historically established as a result of our contract review process, management also elected to implement a standard credit loss provision over any remaining contract assets considered to have a similar low risk of credit loss.

The development of these estimates is based on historic collection trends, accuracy of estimates within contract margin reporting, as well as the expectation that collection patterns, margin reporting, and bad debt expense will continue to adhere to patterns observed in recent years. These expectations were formed based on trends observed as well as current and expected future conditions. Management monitors and reviews the contributing factors to our reserve, and makes any appropriate revisions as they become necessary.

The First Amendment provides for a reduction in the revolving credit facility to permit aggregate borrowings of the Borrowers up to $120,000 with a sublimit of the equivalent of $25,000 U.S. dollars that is available to the Canadian and United Kingdom borrowers in the aggregate, and repaid and terminated the outstanding term loan by drawing funds on the revolving credit facility. The First Amendment provides additional $5,000 annual reductions to the revolving credit facility beginning on December 31, 2020 through the maturity of the facility on April 30, 2024.

Borrowings under the First Amendment bear interest at rates based upon either the base rate or Euro-rate plus applicable margins. The applicable margins have been adjusted as part of the First Amendment and are dictated by the ratio of the Company’s total net indebtedness to the Company’s consolidated earnings before interest, taxes, depreciation, and amortization (“Consolidated EBITDA”) for four trailing quarters, as defined in the Credit Agreement. The base rate is the highest of (a) the Overnight Bank Funding Rate plus 50 basis points, (b) the Prime Rate, or (c) the Daily Euro-rate plus 100 basis points (each as defined in the Credit Agreement) and an increase to the interest rate floor to 100 basis points. The base rate and Euro-rate spreads range from 100 to 200 basis points and 200 to 300 basis points, respectively.

The First Amendment further provides for modifications to the financial covenants as defined in the Credit Agreement. The First Amendment modified three financial covenants in the Credit Agreement: (a) Maximum Gross Leverage Ratio, defined as the

Company’s Consolidated Indebtedness divided by the Company’s Consolidated EBITDA, which must not exceed, other than during a period of four consecutive fiscal quarters of the Company beginning with a fiscal quarter during which the Company consummates a permitted acquisition, and including such fiscal quarter and the immediately three succeeding fiscal quarters (the “Acquisition Period”), (i) 3.25 to 1.00 for the testing period ended June 30, 2020, 3.00 to 1.00 for the testing periods ending September 30, 2020 through March 31, 2022, and 2.75 to 1.00 for the testing periods June 30, 2022 and thereafter, and (ii) 3.50 to 1.00 for the testing period ended June 30, 2020, 3.25 to 1.00 for the testing periods ending September 30, 2020 through March 31, 2022, and 3.00 to 1.00 for the testing periods ending June 30, 2022 and thereafter occurring during an Acquisition Period; (b) Minimum Consolidated Fixed Charge Coverage Ratio, defined as the Company's Consolidated EBITDA divided by the Company's Fixed Charges, which must be a minimum of 1.00 to 1.00 for the testing period ended June 30, 2020, 1.05 to 1.00 for the testing periods ending September 30, 2020 through June 30, 2021, 1.15 to 1.00 for the testing periods ending September 30, 2021 through June 30, 2022, and 1.25 to 1.00 for the testing periods ending September 30, 2022 and thereafter; and (c) Minimum Working Capital to Revolving Facility Usage Ratio, defined as the sum of 50% of the inventory and 85% of the accounts receivable of the Borrowers and certain other Guarantors divided by the dollar equivalent sum of the outstanding revolving credit loans, the outstanding swing loans, and the letter of credit obligations (the “Revolving Facility Usage”), which must not be less than 1.50 to 1.00. In addition, the First Amendment modifies the definition of Consolidated EBITDA to allow for certain additional adjustments. The First Amendment also includes changes to the non-financial covenants as defined in the Credit Agreement by increasing the basket for dispositions from $25,000 to $40,000. The Credit Agreement’s incremental loan feature permits the Company to increase the available revolving borrowings under the facility by up to an additional $50,000 subject to the Company’s receipt of increased commitments from existing or new lenders and the satisfaction of certain conditions.

The Company’s and the domestic, Canadian, and United Kingdom guarantors’ (the “Guarantors”) obligations under the Credit Agreement are secured by the grant of a security interest by the Borrowers and Guarantors in substantially all of the personal property owned by such entities. Additionally, the equity interests in each of the loan parties, other than the Company, and the equity interests held by each loan party in its respective domestic subsidiaries, have been pledged to the lenders as collateral for the lending obligations.

The Credit Agreement permits the Company to pay dividends and make distributions and redemptions with respect to its stock provided no event of default or potential default (as defined in the Credit Agreement) has occurred prior to or after giving effect to the dividend, distribution, or redemption. Additionally, the Credit Agreement permits the Company to complete acquisitions so long as (a) no event of default or potential default has occurred prior to or as a result of such acquisition; (b) the liquidity of the Borrowers is not less than $25,000 prior to and after giving effect to such acquisition; and (c) the aggregate consideration for the acquisition did not exceed: (i) $50,000 per acquisition; (ii) $50,000 in the aggregate for multiple acquisitions entered into during four consecutive quarters; and (iii) $100,000 in the aggregate over the term of the Credit Agreement.

Other restrictions exist at all times including, but not limited to, limitations on the Company’s sale of assets and the incurrence by either the Borrowers or the non-borrower subsidiaries of the Company of other indebtedness, guarantees, and liens.

As of September 30, 2020, the Company was in compliance with the covenants in the First Amendment.

As of September 30, 2020, the Company had outstanding letters of credit of approximately $1,043 and had net available borrowing capacity of $70,105. The maturity date of the facility is April 30, 2024.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

The Company determines the fair value of assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair values are based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations. The fair value hierarchy is based on whether the inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s own assumptions of what market participants would use. The fair value hierarchy includes three levels of inputs that may be used to measure fair value as described below:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

The classification of a financial asset or liability within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Cash equivalents - Included within “Cash and cash equivalents” in the Condensed Consolidated Balance Sheets are investments in non-domestic term deposits. The carrying amounts approximate fair value because of the short maturity of the instruments.

LIBOR-based interest rate swaps - To reduce the impact of interest rate changes on outstanding variable-rate debt, the Company entered into forward starting LIBOR-based interest rate swaps with notional values totaling $50,000. The fair value of the interest rate swaps is based on market-observable forward interest rates and represents the estimated amount that the Company would pay to terminate the agreements. As such, the swap agreements are classified as Level 2 within the fair value hierarchy. As of September 30, 2020 and December 31, 2019, the interest rate swaps were recorded within “Other accrued liabilities” in the Condensed Consolidated Balance Sheets.

	Fair Value Measurements at Reporting Date								Fair Value Measurements at Reporting Date

The Company accounts for the interest rate swaps as cash flow hedges and the objective of the hedges is to offset the expected interest variability on payments associated with the interest rate on our debt. The Company de-designated its cash flow hedges and accounts for all existing and future interest rate swaps on a mark-to-market basis with changes in fair value recorded in current period earnings. In connection with this de-designation, the Company froze the balances recorded in “Accumulated other comprehesive loss” at June 30, 2020 and reclassifies balances to earnings as the underlying physical transactions occur, unless it is no longer probable that the physical transaction will occur at which time the related gains deferred in Other Comprehesive Income will be immediately recorded in earnings. The gains and losses related to the interest rate swaps are reclassified from “Accumulated other comprehensive loss” in the Condensed Consolidated Balance Sheets and included in “Interest expense - net” in the Condensed Consolidated Statements of Operations as the interest expense from our debt is recognized. For the three months ended September 30, 2020 and 2019, we recognized interest expense of $178 and interest income of $21, respectively, and for the nine months ended September 30, 2020 and 2019, we recognized interest expense of $468 and interest income of $142, respectively, from interest rate swaps.

The Company recognized interest income of $234 from the change in fair value of the interest rate swaps in “Interest expense - net” in the Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2020.

In accordance with the provisions of the FASB's Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurement,” the Company measures certain nonfinancial assets and liabilities at fair value, which are recognized and disclosed on a nonrecurring basis.

Stock-Based Compensation

Share-based Payment Arrangement, Noncash Expense [Abstract]

Stock-based Compensation

Stock-based Compensation

The Company applies the provisions of ASC 718, “Compensation – Stock Compensation,” to account for the Company’s stock-based compensation. Stock-based compensation cost is measured at the grant date based on the calculated fair value of the award and is recognized over the employees’ requisite service periods. The Company recorded stock compensation expense related to restricted stock awards and performance share units of $604 and $876 for the three months ended September 30, 2020 and 2019, respectively, and $1,842 and $2,910 for the nine months ended September 30, 2020 and 2019, respectively. As of September 30, 2020, unrecognized compensation expense for unvested awards approximated $4,096. The Company expects to recognize this expense over the upcoming 3.5 years through March 2024.

Shares issued as a result of vested stock-based compensation awards generally will be from previously issued shares that have been reacquired by the Company and held as treasury stock or authorized and previously unissued common stock.

Restricted Stock Awards and Performance Share Units

Under the 2006 Omnibus Plan, the Company grants eligible employees restricted stock and performance share units. The forfeitable restricted stock awards granted generally time-vest ratably over a three-year period, unless indicated otherwise by the underlying restricted stock agreement. Since May 2018, awards of restricted stock have been subject to a minimum one-year vesting period, including those granted to non-employee directors. Prior to May 2018, awards to non-employee directors were made in fully-vested shares. Performance share units are offered annually under separate three-year long-term incentive programs. Performance share units are subject to forfeiture and will be converted into common stock of the Company based upon the Company’s performance relative to performance measures and conversion multiples, as defined in the underlying program. If the Company’s estimate of the number of performance share units expected to vest changes in a subsequent accounting period, cumulative compensation expense could increase or decrease. The change will be recognized in the current period for the vested shares and would change future expense over the remaining vesting period.

Since May 1, 2017, non-employee directors have been permitted to defer receipt of annual stock awards and equity elected to be received in lieu of quarterly cash compensation. If so elected, these deferred stock units will be issued as common stock six months

after separation from their service on the Board of Directors. Since May 2018, no non-employee directors have elected the option to receive deferred stock units of the Company’s common stock in lieu of director cash compensation.

In February 2020, the Compensation Committee approved the 2020 Performance Share Unit Program and the Executive Annual Incentive Compensation Plan (consisting of cash and equity components).

The following table summarizes the restricted stock awards, deferred stock units, and performance share units activity for the nine months ended September 30, 2020:

Union Pacific Railroad (“UPRR”) Concrete Tie Matter

On March 13, 2019, the Company and its subsidiary, CXT Incorporated (“CXT”), entered into a Settlement Agreement (the “Settlement Agreement”) with UPRR to resolve the pending litigation in the matter of Union Pacific Railroad Company v. L.B. Foster Company and CXT Incorporated, Case No. CI 15-564, in the District Court for Douglas County, Nebraska.

Under the Settlement Agreement, the Company and CXT will pay UPRR the aggregate amount of $50,000 without pre-judgment interest, which began with a $2,000 immediate payment, and with the remaining $48,000 paid in installments over a six-year period commencing on the effective date of the Settlement Agreement through December 2024 pursuant to a Promissory Note. Additionally, commencing in January 2019 and through December 2024, UPRR agreed to purchase and has been purchasing from the Company and its subsidiaries and affiliates, a cumulative total amount of $48,000 of products and services, targeting $8,000 of annual purchases per year beginning March 13, 2019 per letters of intent under the Settlement Agreement. The Settlement Agreement also includes a mutual release of all claims and liability regarding or relating to all CXT pre-stressed concrete railroad ties with no admission of liability and dismissal of the litigation with prejudice.

The expected payments under the UPRR Settlement Agreement for the remainder of the year ending December 31, 2020 and thereafter are as follows:

Year Ending December 31,
Remainder of 2020	$	4,000

Environmental and Legal Proceedings

The Company is subject to national, state, foreign, provincial, and/or local laws and regulations relating to the protection of the environment. The Company’s efforts to comply with environmental regulations may have an adverse effect on its future earnings.

On June 5, 2017, a General Notice Letter was received from the United States Environmental Protection Agency (“EPA”) indicating that the Company may be a potentially responsible party (“PRP”) regarding the Portland Harbor Superfund Site cleanup along with numerous other companies. More than 140 other companies received such a notice. The Company and a predecessor owned and operated a facility near the harbor site for a period prior to 1982. The net present value and undiscounted costs of the selected remedy throughout the harbor site are estimated by the EPA to be approximately $1.1 billion and $1.7 billion, respectively, and the remedial work is expected to take as long as 13 years to complete. The Company is reviewing the basis for its identification by the EPA and the nature of the historic operations of a Company predecessor near the site. Additionally, the Company executed a PRP agreement which provides for a private allocation process among almost 100 PRPs in a working group whose work is ongoing. On March 26, 2020, the EPA issued a Unilateral Administrative Order to two parties requiring them to perform remedial design work for that portion of the Harbor Superfund Site that includes the area closest to the facility; the Company was not a recipient of this Unilateral Administrative Order. We cannot predict the ultimate impact of these proceedings because of the large number of PRPs involved throughout the harbor site, the degree of contamination of various wastes, varying environmental impacts throughout the harbor site, the scarcity of data related to the facility once operated by the Company and a predecessor, and the speculative nature of the remediation costs. Based upon information currently available, management does not believe that the Company’s alleged PRP status regarding the Portland Harbor Superfund Site or other compliance with the present environmental protection laws will have a material adverse effect on the financial condition, results of operations, cash flows, competitive position, or capital expenditures of the Company.

As of September 30, 2020 and December 31, 2019, the Company maintained environmental reserves approximating $2,562 and $2,608, respectively. The following table sets forth the Company’s environmental obligation:

	Environmental liability
Balance as of December 31, 2019	$	2,608
Environmental obligations utilized	(46)
Balance as of September 30, 2020	$	2,562

The Company is also subject to other legal proceedings and claims that arise in the ordinary course of its business. Legal actions are subject to inherent uncertainties, and future events could change management's assessment of the probability or estimated amount of potential losses from pending or threatened legal actions. Based on available information, it is the opinion of management that the ultimate resolution of pending or threatened legal actions, both individually and in the aggregate, will not result in losses having a material adverse effect on the Company's financial position or liquidity as of September 30, 2020.

If management believes that, based on available information, it is at least reasonably possible that a material loss (or additional material loss in excess of any accrual) will be incurred in connection with any legal actions, the Company discloses an estimate of the possible loss or range of loss, either individually or in the aggregate, as appropriate, if such an estimate can be made, or discloses that an estimate cannot be made. Based on the Company's assessment as of September 30, 2020, no such disclosures were considered necessary.

For the three months ended September 30, 2020 and 2019, the Company recorded an income tax benefit of $13,742 on pre-tax income from continuing operations of $2,836 and an income tax expense of $836 on pre-tax income from continuing operations of $4,590, respectively, for effective income tax rates of (484.6)% and 18.2%, respectively. For the nine months ended September 30, 2020 and 2019, the Company recorded an income tax benefit of $11,698 on pre-tax income from continuing operations of $11,845 and an income tax expense of $3,883 on pre-tax income from continuing operations of $21,656, respectively, for effective income tax rates of (98.8)% and 17.9%, respectively. The Company’s income tax benefit from continuing operations for the three- and nine-month periods ended September 30, 2020 included a discrete income tax benefit of $15,824 related to the disposition of the Test and Inspection Services business. In addition to the impact of discrete items, the Company's effective tax rate for the nine months ended September 30, 2020 differed from the federal statutory rate of 21% primarily due to state income taxes, nondeductible expenses, and global intangible low-taxed income (“GILTI”) inclusions.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted in response to the COVID-19 pandemic. The CARES Act contains several corporate income tax provisions, including providing for a five-year carryback of net operating losses (“NOL”) generated in tax years 2018 through 2020, removing the 80% taxable income limitation on utilization of those NOLs if carried back to prior tax years or utilized in tax years beginning before 2021, making remaining alternative minimum tax (“AMT”) credits immediately refundable, and temporarily relaxing the interest deductibility rules by raising the adjusted taxable income limitation from 30% to 50% for tax years 2019 and 2020. As of September 30, 2020, the Company has recorded an income tax receivable of $9,008 to reflect expected tax refunds of federal taxes paid within the five year NOL carryback period.

The amendments are effective for all entities as of March 12, 2020 through December 31, 2022. We are currently evaluating the impacts of the provisions of ASU 2020-04 on our financial condition, results of operations, and cash flows.

Recently Adopted Accounting Standards

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 added a new impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses and presents financial assets measured at amortized cost basis at the net amount expected to be collected upon inception. The CECL model applies to trade receivables, other receivables, and most debt instruments. The CECL model does not have a minimum threshold for recognition of impairment losses, and entities must measure expected credit losses on assets that have a low risk of loss. The Company adopted the provisions of ASU 2016-13 on January 1, 2020, using the modified retrospective approach as of the beginning of the period of adoption. In accordance with the standard, the Company evaluated its allowance for credit losses for trade receivables and contract assets, the only assets held by the Company that were impacted by the scope of the standard. The adoption of ASU 2016-13 had no material effect on the Company’s financial position or results of operations, and no adjustment to January 1, 2020 Retained earnings was recorded. The Company has presented the disclosures required by this new standard in Note 6 Accounts Receivable and Note 7 Inventory.

In August 2018, the FASB issued ASU 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software” (“ASU 2018-15”). ASU 2018-15 requires capitalization of certain implementation costs incurred in a cloud computing arrangement that qualifies as a service contract. The amendments in ASU 2018-15 are effective for fiscal years beginning after December 15, 2019 and for interim periods therein with early adoption permitted. The adoption of ASU 2018-15 had no impact on the Company’s consolidated financial statements and related disclosures.

Inventory

Inventories of the Company are valued at average cost or net realizable value, whichever is lower.

Share based compensation

The Company applies the provisions of ASC 718, “Compensation – Stock Compensation,” to account for the Company’s stock-based compensation. Stock-based compensation cost is measured at the grant date based on the calculated fair value of the award and is recognized over the employees’ requisite service periods
