Accounting Policies [Abstract]
Financial Statements	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 8 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 March 31, 2022 and December 31, 2021 and its Condensed Consolidated Statements of Operations, Condensed Consolidated Statements of Comprehensive Loss, Condensed Consolidated Statements of Cash Flows, and Condensed Consolidated Statements of Stockholders’ Equity for the three months ended March 31, 2022 and 2021 have been included. However, actual results could differ from those estimates and changes in those estimates are recorded when known. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. The Condensed Consolidated Balance Sheet as of December 31, 2021 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, 2021. 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. Reclassifications Certain accounts in the prior year consolidated financial statements have been reclassified for comparative purposes principally to conform to the presentation of the current year period. Effective for the quarter and year ended December 31, 2021, the Company implemented operational changes in how its Chief Operating Decision Maker (“CODM”) manages its businesses, including resource allocation and operating decisions. As a result of these changes, the Company now has three reporting segments, representing the individual businesses that are run separately under the new structure: Rail, Technologies, and Services; Precast Concrete Products; and Steel Products and Measurement. The Company has revised the information for all periods presented in this Quarterly Report on Form 10-Q to reflect these reclassifications. Recently Issued Accounting Standards In March 2020 and as clarified in January 2021, 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 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. The Company is currently evaluating the impacts of the provisions of ASU 2020-04 on its financial condition, results of operations, and cash flows.

Segment Reporting [Abstract]

Business Segments

Business Segments The Company is a global solutions provider of engineered, manufactured products and services that builds and supports infrastructure. The Company’s innovative engineering and product development solutions address the safety, reliability, and performance needs of its customers’ most challenging requirements. The Company maintains locations in North America, South America, Europe, and Asia. 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 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 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, 2021.

The following table illustrates the Company’s revenues and profit (loss) from operations by segment for the periods indicated:


	Three Months Ended March 31, 2022				Three Months Ended March 31, 2021

Total	$	98,794	$	(1,900)	$	116,080	$	1,185

Segment profit (loss) 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 (loss) profit to the Company’s consolidated total for the periods presented:

Revenue

3 Months Ended

Revenue from Contract with Customer [Abstract]

Revenue

Revenue from products or services provided to customers over time accounted for 30.7% and 25.3% of revenue for the three months ended March 31, 2022 and 2021, respectively. The majority of revenue under these long-term agreements is 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 its performance to date under the terms of the contract. Revenue recognized over time using an input measure was $19,322 and $21,108 for the three months ended March 31, 2022 and 2021, 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 $10,981 and $8,264 for the three months ended March 31, 2022 and 2021, respectively. As of March 31, 2022 and December 31, 2021, the Company had contract assets of $34,268 and $36,179, respectively, that were recorded within the Condensed Consolidated Balance Sheets. As of March 31, 2022 and December 31, 2021, the Company had contract liabilities of $3,682 and $3,235, 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 69.3% and 74.7% of revenue for the three months ended March 31, 2022 and 2021. 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 (included in “Contract assets”), and billings in excess of costs (contract liabilities, included in “Deferred revenue”) within the Condensed Consolidated Balance Sheets.

Significant changes in contract assets during the three months ended March 31, 2022 included transfers of $11,607 from the contract assets balance as of December 31, 2021 to accounts receivable. Significant changes in contract liabilities during the three months ended March 31, 2022 resulted from increases of $1,957 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 March 31, 2022 and 2021 of $1,441 and $676, respectively, which were included in contract liabilities at the beginning of each period.

The Company records provisions related to the allowance for credit losses associated with contract assets. Provisions are recorded based upon a specific review of individual contracts as necessary, and a standard provision over any remaining contract assets pooled together based on similar risk of credit loss. The development of these provisions are 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 are formed based on trends observed as well as current and expected future conditions.

As of March 31, 2022, the Company had approximately $244,618 of obligations under new contracts and remaining performance obligations, which is also referred to as backlog. Approximately 10.8% of the March 31, 2022 backlog was related to projects that are anticipated to extend beyond March 31, 2023.

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 March 31, 2022.

Accounts Receivable Additional Disclosures [Abstract]

Accounts Receivable

Accounts ReceivableThe 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 March 31, 2022 and December 31, 2021 have been reduced by an allowance for credit

losses of $423 and $547, respectively. Changes in reserves for uncollectible accounts, which are recorded as part of “Selling and administrative expenses” within the Condensed Consolidated Statements of Operations, resulted in expense of $61 and income of $22 for the three months ended March 31, 2022 and 2021, respectively.

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 considers 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, including the impacts of the COVID-19 pandemic. Management maintains stringent credit review practices and works to maintain positive customer relationships to further mitigate credit risk.

The following table sets forth the Company’s allowance for credit losses:


	Allowance for Credit Losses

On August 13, 2021, the Company, its domestic subsidiaries, and certain of its Canadian and United Kingdom subsidiaries (collectively, the “Borrowers”), entered into the Fourth Amended and Restated Credit Agreement (the “Credit Agreement”) with PNC Bank, N.A., Citizens Bank, N.A., Wells Fargo Bank, National Association, Bank of America, N.A., and BMO Harris Bank, National Association. The Credit Agreement modifies the prior revolving credit facility, as amended, on more favorable terms and extends the maturity date from April 30, 2024 to August 13, 2026. The Credit Agreement provides for a five-year, revolving credit facility that permits aggregate borrowings of the Borrowers up to $130,000 (a $15,000 increase over the previous commitment) 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. The Credit Agreement’s incremental loan feature permits the Company to increase the available commitments 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 obligation of the Company and its domestic, Canadian, and United Kingdom subsidiaries (the “Guarantors”) under the Credit Agreement will be secured by the grant of a security interest by the Borrowers and Guarantors in substantially all of the assets 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 their subsidiaries, will be pledged to the lenders as collateral for the lending obligations.

Borrowings under the Credit Agreement will bear interest at rates based upon either the base rate or LIBOR rate plus applicable margins. Applicable margins are dictated by the ratio of the Company’s total net indebtedness to the Company’s 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 LIBOR rate plus 100 basis points so long as the Daily LIBOR Rate is offered, ascertainable, and not unlawful (each as defined in the Credit Agreement). The base rate and LIBOR rate spreads range from 25 to 125 basis points and 125 to 225 basis points, respectively.

The Credit Agreement includes two financial covenants: (a) Maximum Gross Leverage Ratio, defined as the Company’s consolidated Indebtedness divided by the Company’s consolidated EBITDA, which must not exceed (i) 3.25 to 1.00 for all testing periods other than during an Acquisition Period, and (ii) 3.50 to 1.00 for all testing periods occurring during an Acquisition Period (as defined in the Credit Agreement), and (b) Minimum Consolidated Fixed Charge Coverage Ratio, defined as the Company’s consolidated EBITDA divided by the Company’s Fixed Charges (as defined in the Credit Agreement), which must be more than 1.05 to 1.00.

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 $15,000 prior to and after giving effect to such acquisition; and (c) the aggregate consideration for the acquisition does not exceed: (i) $50,000 per acquisition, so long as the Gross Leverage Ratio (as defined in the Credit Agreement) is less than or equal to 2.75 after giving effect to such acquisition; or (ii) $75,000 per acquisition, so long as the Gross Leverage Ratio is less than or equal to 1.75 after giving effect to such acquisition.

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 March 31, 2022, the Company was in compliance with the covenants in the Credit Agreement, as amended. As of March 31, 2022, the Company had outstanding letters of credit of approximately $636 and had net available borrowing capacity of $93,868, subject to covenant restrictions. The maturity date of the facility is August 13, 2026.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Stock-Based Compensation

3 Months Ended

Mar. 31, 2022

Share-based Payment Arrangement, Noncash Expense [Abstract]

Stock-Based Compensation

Stock-Based CompensationThe Company applies the provisions of the FASB’s Accounting Standards Codification (“ASC”) Topic 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-based compensation expense related to restricted stock awards and performance share units of $258 and $827 for the three months ended March 31, 2022 and 2021, respectively. As of March 31, 2022, unrecognized compensation expense for unvested awards approximated $4,064. The Company expects to recognize this expense over the upcoming 3.9 years through March 2026.

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, Performance Share Units, and Performance-Based Stock Awards

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 award 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. 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 2022, the Compensation Committee approved the 2022 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 three months ended March 31, 2022:


	Restricted Stock	Deferred Stock Units	Performance Share Units	Weighted Average Grant Date Fair Value
Outstanding as of December 31, 2021	135,704	74,950	116,571	$	19.75

Fair Value Measurements

3 Months Ended

Mar. 31, 2022

Fair Value Disclosures [Abstract]

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 in “Cash and cash equivalents” within 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 a forward starting LIBOR-based interest rate swaps with notional values totaling $50,000 and $20,000 effective February 2017 and March 2022, respectively. The fair value of the interest rate swaps are 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 March 31, 2022 and December 31, 2021, the interest rate swaps were recorded in "Other current assets" when the interest rate swaps’ fair market value are in an asset position, and "Other accrued liabilities" when in a liability position within our Consolidated Balance Sheets.


	Fair Value Measurements at Reporting Date								Fair Value Measurements at Reporting Date
	March 31, 2022		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		December 31, 2021		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Total liabilities	$	—	$	—	$	—	$	—	$	159	$	—	$	159	$	—

The $20,000 interest rate swaps that become effective March 2022 are accounted for 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 gains and losses related to the interest rate swaps are reclassified from “Accumulated other comprehensive loss” in our Condensed Consolidated Balance Sheets and included in “Interest expense - net” in our Condensed Consolidated Statements of Operations as the interest expense from our debt is recognized.

The Company accounted for the $50,000 of interest rate swaps that became effective February 2017 as cash flow hedges, these interest rate swaps expired February 2022.

For the three months ended March 31, 2022 and 2021, the Company recognized interest expense of $97 and $235, respectively, from interest rate swaps.

In accordance with the provisions of 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.

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. During the third quarter of 2021, in connection with the Company’s divestiture of its Piling Products division, the targeted annual purchases per year have been reduced to $6,000 for

2021 through 2024. 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, 2022 and thereafter are as follows:

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. These costs may increase given that the remedy will not be initiated or completed for several years. 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. The Company cannot predict the ultimate impact of these proceedings because of the large number of PRPs involved throughout the harbor site, the size and extent of the 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, potential comparative liability between the allocation parties and regarding non-participants, 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 more information develops and the allocation process is completed, and given the resolution of factors like those described above, an unfavorable resolution could have a material adverse effect.

As of March 31, 2022 and December 31, 2021, the Company maintained environmental reserves approximating $2,507 and $2,519, respectively. The following table sets forth the Company’s environmental obligation:


	Environmental liability
Balance as of December 31, 2021	$	2,519

Environmental obligations utilized	(12)
Balance as of March 31, 2022	$	2,507

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 March 31, 2022.

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 March 31, 2022, no such disclosures were considered necessary.

Accounting Policies [Abstract]
Basis of Presentation	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 8 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 March 31, 2022 and December 31, 2021 and its Condensed Consolidated Statements of Operations, Condensed Consolidated Statements of Comprehensive Loss, Condensed Consolidated Statements of Cash Flows, and Condensed Consolidated Statements of Stockholders’ Equity for the three months ended March 31, 2022 and 2021 have been included. However, actual results could differ from those estimates and changes in those estimates are recorded when known. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. The Condensed Consolidated Balance Sheet as of December 31, 2021 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, 2021. 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.
Reclassifications	Reclassifications Certain accounts in the prior year consolidated financial statements have been reclassified for comparative purposes principally to conform to the presentation of the current year period. Effective for the quarter and year ended December 31, 2021, the Company implemented operational changes in how its Chief Operating Decision Maker (“CODM”) manages its businesses, including resource allocation and operating decisions. As a result of these changes, the Company now has three reporting segments, representing the individual businesses that are run separately under the new structure: Rail, Technologies, and Services; Precast Concrete Products; and Steel Products and Measurement. The Company has revised the information for all periods presented in this Quarterly Report on Form 10-Q to reflect these reclassifications.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In March 2020 and as clarified in January 2021, 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 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. The Company is currently evaluating the impacts of the provisions of ASU 2020-04 on its financial condition, results of operations, and cash flows.
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 the FASB’s Accounting Standards Codification (“ASC”) Topic 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.
