Forward-Looking Statements

This Annual Report on Form 10-K 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.” Forward-looking statements 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 Annual Report on Form 10-K are based on management’s current expectations and assumptions about future events that involve inherent risks and uncertainties and may concern, among other things, L.B. Foster Company’s (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: a resumption of the economic slowdown we experienced in previous years in the markets we serve; a decrease in freight or passenger rail traffic; environmental matters, including any costs associated with any remediation and monitoring; the risk of doing business in international markets; global health epidemics; our ability to effectuate our strategy, including cost reduction initiatives, and our ability to effectively integrate acquired businesses and realize anticipated benefits; costs of and impacts associated with shareholder activism; the timeliness and availability of materials from our major suppliers, 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 these amounts; foreign currency fluctuations; inflation; domestic and foreign government regulations, including tariffs; economic conditions and regulatory changes caused by the United Kingdom’s exit from the European Union in January 2020; sustained declines in energy prices; 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 this Annual Report on Form 10-K and our other 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.

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. As used herein, “L.B. Foster,” the “Company,” “we,” “us,” and “our” or similar references refer collectively to L.B. Foster Company and its subsidiaries, unless the context indicates otherwise.

The following table shows the net sales generated by each business segment as a percentage of total net sales for the years ended December 31, 2019 and 2018:

	Percentage of Net Sales
	2019		2018
Rail Products and Services	49	%	51	%
Construction Products	28		25
Tubular and Energy Services	23		24
	100	%	100	%

Financial information concerning these segments is set forth in Part II, Item 8, Financial Statements and Supplementary Data, Note 2 to the Consolidated Financial Statements contained in this Annual Report on Form 10-K, which is incorporated by reference into this Item 1.

Rail Products and Services

The Company’s Rail Products and Services (“Rail”) segment is comprised of several manufacturing, distribution, and service businesses that provide a variety of products and services for freight and passenger railroads and industrial companies throughout the world. The Rail segment has sales offices throughout North America and Europe, and works on rail projects where it offers products manufactured by the Company, or sourced from numerous supply chain partners, and also offers aftermarket services. The Rail segment is comprised of the following business units: Rail Products and Rail Technologies.

Rail Products

The Rail Products business is comprised of the Company’s Rail Distribution, Allegheny Rail Products, Transit Products, and Concrete Tie divisions.

Rail Distribution sells new rail mainly to passenger and short line freight railroads, industrial companies, and rail contractors for the replacement of existing lines or expansion of new lines. Rail accessories sold by the Rail Distribution division include track spikes, bolts, angle bars, and other products required to install or maintain rail lines. These products are manufactured by the Company or purchased from other manufacturers and distributed accordingly. Rail Distribution also sells trackwork products to Class II and III railroads, industrial, and export markets.

The Company’s Allegheny Rail Products (“ARP”) division engineers and fabricates insulated rail joints and related accessories for freight and passenger railroads and industrial customers. Insulated joints are manufactured domestically at the Company’s facilities in Pueblo, CO and Niles, OH.

The Company’s Transit Products division supplies power rail, direct fixation fasteners, coverboards, and special accessories primarily for passenger railroad systems. These products are fabricated at Company facilities or by subcontractors and are usually sold by sealed bid to passenger railroads or to rail contractors.

The Concrete Tie division manufactures engineered concrete railroad ties for freight and passenger railroads and industrial companies at its facility in Spokane, WA.

Rail Technologies

The Company’s Rail Technologies business unit engineers, manufactures, and fabricates friction management products and application systems, railroad condition monitoring systems and equipment, wheel impact load detection, fire protection systems, rail anchors and spikes, wayside data collection and management systems, epoxy and nylon-encapsulated insulated rail joints, track fasteners, and also provides aftermarket services. The Company’s friction management products control the friction at the rail/wheel interface, which help our customers to reduce fuel consumption, improve operating efficiencies, extend the life of operating assets such as rail and wheels, reduce track stresses, and lower the related maintenance and operating costs. Friction management products include mobile and wayside systems that apply lubricants and liquid or solid friction modifiers. In addition, the business unit provides controls, display, and telecommunication solutions for the transit, control room, and customer information and display sectors. These products and systems are designed, engineered, manufactured, fabricated, serviced, and marketed by certain wholly-owned subsidiaries located in the United States, Canada, the United Kingdom (“U.K.”), and Germany.

4

Construction Products

The Construction Products (“Construction”) segment is composed of the following business units: Piling and Fabricated Bridge Products and Precast Concrete Products.

Piling and Fabricated Bridge Products

The Piling and Fabricated Bridge Products business unit sells or rents piling products and manufactures fabricated steel and aluminum bridge products. Sheet piling products are interlocking structural steel sections that are generally used to provide lateral support at construction sites. Bearing piling products are steel H-beam sections which are driven into the ground for support of structures such as bridge piers and high-rise buildings. Piling is often used in water and land applications, including cellular cofferdams and OPEN CELL^® structures in inland river systems and ports.

Piling products are sourced from various manufacturers and either sold or rented to project owners and contractors. The Piling division, via a sales force deployed throughout the United States, markets and sells piling products both domestically and internationally. This division offers its customers various types and dimensions of structural beam piling, sheet piling, and pipe piling. The Company is the primary distributor of domestic steel sheet piling for its primary supplier.

The Fabricated Bridge Products facility in Bedford, PA manufactures a number of fabricated steel and aluminum products primarily for the highway, bridge, and transit industries, including concrete reinforced steel grid deck, open steel grid deck, aluminum bridge railing, and stay-in-place steel bridge forms.

Precast Concrete Products

The Precast Concrete Products business unit primarily manufactures concrete buildings for national, state, and municipal parks. This unit manufactures restrooms, concession stands, and other protective storage buildings available in multiple designs, textures, and colors. The Company is a leading high-end supplier in terms of volume, product options, and capabilities. The unit also manufactures various other precast products, such as burial vaults, bridge beams, box culverts, septic tanks, and other custom pre-stressed and precast concrete products. The products are manufactured in Spokane, WA, Hillsboro, TX, and Waverly, WV. The Company ceased precast building operations in Spokane, WA, and commenced precast product operations in Boise, ID, in the first quarter of 2020. This move is part of an initiative focusing on regional growth opportunities and logistical savings associated with fabricating products in a more centralized location closer to the Company’s existing and prospective customer base.

Tubular and Energy Services

The Tubular and Energy Services (“Tubular and Energy”) segment has two business units: Protective Coatings and Measurement Systems business and Test, Inspection, and Threading Services business. The segment provides products and services predominantly to the mid and upstream oil and gas markets.

Protective Coatings and Measurement Systems

The Protective Coatings and Measurement Systems business unit consists of operations at two primary locations. The Birmingham, AL facility coats the outside and inside diameter of pipe primarily for oil and gas transmission pipelines. This location partners with its primary customer, a pipe manufacturer, to market fusion bonded epoxy coatings, abrasion resistant coatings, and internal linings for a wide variety of pipe diameters for use in pipeline projects throughout North America.

The second location is in Willis, TX and consists of two operating facilities. One facility applies specialty outside and inside diameter coatings for a wide variety of pipe diameters for oil and gas transmission, mining, and waste water pipelines, as well as provides custom coatings for specialty pipe fittings and connections. The second facility manufactures and provides turnkey solutions for metering and injection systems for the oil, and, to a lesser extent, gas industry. This location operates a fabrication plant that builds metering systems for custody transfer applications, including crude oil and other petroleum-based products. These systems are used at well sites, pipelines, refineries, chemical plants, and loading/unloading facilities. The location also manufactures and installs additive and dye injection systems. These systems are used to inject performance additives and/or dyes into petroleum products.

Test, Inspection, and Threading Services

The Test, Inspection, and Threading Services business unit provides inspection and tubular integrity management services for the upstream oil and gas industry. Services include non-destructive testing, inspection, and other asset integrity services such as repair and threading for Oil Country Tubular Goods (“OCTG”) and drill tools. Inspection and testing of these products, which include replaceable and re-usable products such as casing, production tubing, drill pipe, directional motors, drill collars, and their related equipment, is a critical preventative measure to reinforce personnel and well-site safety, enhance efficiency, and avoid costly equipment failures and well-site shutdowns. The business offers these services in every major oil and gas producing region throughout the United States.

The business also provides asset integrity services such as repair and threading for tubular and drill tools. Our facilities cut, thread, and paint pipe primarily for water well applications in the agriculture industry, municipal water authorities, and OCTG markets.

Marketing and Competition

L.B. Foster Company generally markets its Rail Products and Services directly in all major industrial areas of the United States, Canada, and Europe. The Construction Products and Tubular and Energy Services are primarily marketed domestically. The Company employs a sales force of approximately 80 people that is supplemented with a network of agents across Europe, South America, and Asia to reach current customers and cultivate potential customers in these areas. For the years ended 2019 and 2018, approximately 19% and 23%, respectively, of the Company’s total sales were outside the United States.

The major markets for the Company’s products are highly competitive. Product availability, quality, service, and price are principal factors of competition within each of these markets. No other company provides the same product mix to the various markets the Company serves. However, there are one or more companies that compete with the Company in each product line. Therefore, the Company faces significant competition from different groups of companies.

During 2019 and 2018, no single customer accounted for more than 10% of the Company’s consolidated net sales.

Raw Materials and Supplies

Most of the Company’s products are purchased in the form of finished or semi-finished products. The Company purchases the majority of its supplies from domestic and foreign steel producers. Generally, the Company has a number of vendor options. However, the Company has an arrangement with a steel mill to distribute steel piling in North America. Should piling from its present supplier not be available for any reason, the Company risks not being able to provide such product to its customers.

The Company’s purchases from foreign suppliers are subject to foreign currency exchange rate changes as well as the usual risks associated with changes in international conditions as well as United States and international laws that could impose import restrictions on selected classes of products and for anti-dumping duties if products are sold in the United States at prices that are below specified prices.

Backlog

The Company’s backlog represents the sales price of received customer purchase orders or 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 are rare. Backlog should not be considered a reliable indicator of the Company’s ability to achieve any particular level of revenue or financial performance. The backlog as of December 31, 2019 and 2018 by business segment was as follows:

	December 31,
	2019		2018
Rail Products and Services	$	103,694	$	97,447
Construction Products	92,280		95,419
Tubular and Energy Services	34,093		27,552
Total	$	230,067	$	220,418

Approximately 8.3% of the December 31, 2019 backlog was related to projects that will extend beyond 2020.

Research and Development

Expenditures for research and development approximated $2,614 and $2,646 in 2019 and 2018, respectively. These expenditures were predominately associated with expanding product lines and capabilities within the Company’s Rail Technologies business unit.

Patents and Trademarks

The Company owns a number of domestic and international patents and trademarks, primarily related to its Rail Technologies products. The Company’s business segments are not dependent upon any individual patents or related group of patents, nor any individual licenses or distribution rights. The Company believes that, in the aggregate, the rights under its patents, trademarks, and licenses are generally important to its operations, but it does not consider any individual patent or trademark, nor any licensing or distribution rights related to a specific process or product, to be of material importance in relation to its total business.

Environmental Disclosures

Information regarding environmental matters is included in Part II, Item 8, Financial Statements and Supplementary Data, Note 18 to the Consolidated Financial Statements included herein, which is incorporated by reference into this Item 1.

Employees and Employee Relations

As of December 31, 2019, the Company had approximately 1,330 employees, 1,161 located within the Americas and 169 located in Europe. There were 681 hourly production workers and 649 salaried employees. Of the hourly production workers, approximately 111 were represented by unions. The Company has not suffered any major work stoppages during the past five years and considers its relations with its employees to be satisfactory.

6

Three collective bargaining agreements covering approximately 33, 23, and 55 employees are scheduled to expire in March 2020, August 2021, and September 2021, respectively. As a result of the Company’s relocation of the concrete products operations from Spokane, WA to Boise, ID, a separation agreement has been executed with the collective bargaining unit representing the employees affected by this relocation. This agreement had no impact on the employees under the same collective bargaining agreement at the concrete tie operations in Spokane, WA.

Substantially all of the Company’s hourly paid employees are covered by one of the Company’s noncontributory, defined benefit plans or defined contribution plans. Substantially all of the Company’s salaried employees are covered by defined contribution plans.

ITEM 1A. RISK FACTORS

Risks and Uncertainties

We operate in a changing environment that involves numerous known and unknown risks and uncertainties that could have a material and adverse effect on our business, financial condition, and results of operations. The following risks highlight some of the more significant factors that have affected us and could affect us in the future. We may also be affected by unknown risks or risks that we currently believe are immaterial. If any one or more such events actually occur, our business, financial condition, and results of operations could be materially and adversely affected. One should carefully consider the following factors and other information contained in this Annual Report on Form 10-K and any other risks discussed in our other periodic filings with the SEC before deciding to invest in our common stock.

Our inability to successfully manage divestitures and other significant transactions could harm our financial results, business, and prospects.

As part of our business strategy, we may divest businesses or assets, enter into strategic alliances and joint ventures, or make investments to realize anticipated benefits, actions which involve a number of inherent risks and uncertainties. We can give no assurances that the opportunities will be consummated or that financing will be available. We may not be able to achieve the synergies and other benefits we expect from strategic transactions as successfully or as rapidly as projected, if at all.

Our future performance and market value could cause write-downs of long-lived and intangible assets in future periods.

We are required under U.S. generally accepted accounting principles to review intangible assets for impairment when events or changes in circumstances indicate that the carrying value may not be recoverable. In addition, goodwill is required to be tested for impairment at least annually. Factors that may be considered to be a change in circumstances indicating that the carrying value of our intangible assets may not be recoverable include, but are not limited to, a decline in stock price and resulting market capitalization, a significant decrease in the market value of an asset, or a significant decrease in operating or cash flow projections. No impairments of goodwill or long-lived assets were recorded in 2019 or 2018.

No assurances can be given that we will not be required to record future significant charges related to tangible or intangible asset impairments.

Our indebtedness could materially and adversely affect our business, financial condition, and results of operations and prevent us from fulfilling our obligations.

Our indebtedness could materially and adversely affect our business, financial condition, and results of operations. For example, it could:

•require us to dedicate a substantial portion of our cash flows to payments of our indebtedness, which would reduce the availability of our cash flows to fund working capital, capital expenditures, expansion efforts, or other general corporate purposes;

8

•limit our flexibility in planning for, or reacting to, changes in our business and the industries in which we operate;

•place us at a competitive disadvantage compared to our competitors that have less debt; and

•limit, among other things, our ability to borrow additional funds for working capital, capital expenditures, or other general corporate purposes.

Our inability to comply with covenants in place or our inability to make the required principal and interest payments may cause an event of default, which could have a substantial adverse impact to our business, financial condition, and results of operations. There is no assurance that refinancings or asset dispositions could be effected on a timely basis or on satisfactory terms, if at all, particularly if credit market conditions deteriorate. Furthermore, there can be no assurance that refinancings or asset dispositions would be permitted by the terms of our credit agreements or debt instruments. Our existing credit agreements contain, and any future debt agreements we may enter into may contain, certain financial tests and other covenants that limit our ability to incur indebtedness, acquire other businesses, and may impose various other restrictions. Our ability to comply with financial tests may be adversely affected by changes in economic or business conditions beyond our control, and these covenants may limit our ability to take advantage of potential business opportunities as they arise. We cannot be certain that we will be able to comply with the financial tests and other covenants, or, if we fail to do so, that we will be able to obtain waivers or amended terms from our lenders. An uncured default with respect to one or more of the covenants could result in the amounts outstanding being declared immediately due and payable, which may also trigger an obligation to redeem our outstanding debt securities and repay all other outstanding indebtedness. Any such acceleration of our indebtedness would have a material and adverse effect on our business, financial condition, and results of operations.

Certain portions of our variable rate debt, including our revolving credit facility, currently uses LIBOR as a benchmark for establishing the interest rate. The SEC staff has stated that “[i]t is expected that a number of private-sector banks currently reporting information used to set LIBOR will stop doing so after 2021 when their current reporting commitment ends, which could either cause LIBOR to stop publication immediately or cause LIBOR’s regulator to determine that its quality has degraded to the degree that it is no longer representative of its underlying market.” The consequences of this and other developments with respect to LIBOR cannot be entirely predicted but may result in an increase in the interest cost of our variable rate debt.

Prolonged depressed energy prices and other unfavorable changes in U.S., global, or regional economic and market conditions could adversely affect our business.

We could be adversely impacted by prolonged negative changes in economic conditions affecting either our suppliers or customers, as well as the capital markets. Negative changes in government spending may result in delayed or permanent deferrals of existing or potential projects. No assurances can be given that we will be able to successfully mitigate various prolonged uncertainties, including materials cost variability, delayed or reduced customer orders and payments, and access to available capital resources outside of operations.

In addition, volatile market conditions and depressed energy prices could continue for an extended period, which would negatively affect our business prospects and reduce profitability. Historically, oil and natural gas prices have been volatile and are subject to fluctuations in response to changes in supply and demand, market uncertainty, and a variety of additional factors that are beyond our control. Sustained declines or significant and frequent fluctuations in the price of oil and natural gas may have a material and adverse effect on our operations and financial condition.

Our ability to maintain or improve our profitability could be adversely impacted by cost pressures.

Our profitability is dependent upon the efficient use of our resources. Rising inflation, labor costs, labor disruptions, and other increases in costs due to tariffs or other reasons in the geographic areas in which we operate could have a significant adverse impact on our profitability and results of operations.

Management projections, estimates, and judgments may not be indicative of our future performance.

Our management team is required to use certain estimates in preparing our financial statements, including accounting estimates to determine reserves related to litigation, deferred tax assets, and the fair market value of certain assets and liabilities. Certain asset and liability valuations are subject to management’s judgment and actual results are influenced by factors outside our control.

We are required to maintain a valuation allowance for deferred tax assets and record a charge to income if we determine, based on evidence available at the time the determination is made, that it is more likely than not some portion or all of the deferred tax assets will not be realized. This evaluation process involves significant management judgment about assumptions that are subject to change from period to period. The use of different estimates can result in changes in the amount of deferred taxes recognized, which can result in earnings volatility because such changes are reported in current period earnings. See Part II, Item 8, Financial Statements and Supplementary Data, Note 14 to the Consolidated Financial Statements, contained in this Annual Report on Form 10-K, for additional discussion of our deferred taxes.

Our business operates in highly competitive markets and a failure to react to changing market conditions could adversely impact our business.

We face strong competition in each of the markets in which we operate. A slow response to competitor pricing actions and new competitor entries into our product lines could negatively impact our overall pricing. Efforts to improve pricing could negatively impact our sales volume in all product categories. We may be required to invest more heavily to maintain and expand our product

9

offerings. There can be no assurance that new product offerings will be widely accepted in the markets we serve. Significant negative developments in any of these areas could adversely affect our financial results and condition.

If we are unable to protect our intellectual property and prevent its improper use by third parties, our ability to compete may be harmed.

We own a number of patents and trademarks under the intellectual property laws of the United States, Canada, Europe, and other countries in which product sales are possible. However, we have not perfected patent and trademark protection of our proprietary intellectual property for all products in all countries. The decision not to obtain patent and trademark protection in additional countries may result in other companies copying and marketing products that are based upon our proprietary intellectual property. This could impede growth into new markets where we do not have such protections and result in a greater supply of similar products in such markets, which in turn could result in a loss of pricing power and reduced revenue.

Our success is in part dependent on the accuracy and proper utilization of our management information and communications systems.

We are currently working through an enterprise resource program (“ERP”) system transition. Certain divisions of our Company migrated into the new ERP system during 2016, additional divisions migrated during 2019, and certain other divisions may be transitioned during 2020 and subsequent years. The system implementation is intended to enable us to better meet the information requirements of our users, increase our integration efficiencies, and identify additional synergies in the future. The implementation of our ERP system is complex because of the wide range of processes and systems to be integrated across our business. Any disruptions, delays, or deficiencies in the design, operation, or implementation of our various systems, or in the performance of our systems, particularly any disruptions, delays, or deficiencies that impact our operations, could adversely affect our ability to effectively run and manage our business, including our ability to receive, process, ship, and bill for orders in a timely manner or our ability to properly manage our inventory or accurately present our inventory availability or pricing. Project delays, business interruptions, or loss of expected benefits could have a material and adverse effect on our business, financial condition, or results of operations.

We are subject to cybersecurity risks and may incur increasing costs in an effort to minimize those risks.

Our business employs systems and websites that allow for the storage and transmission of proprietary or confidential information regarding our customers, employees, job applicants, and other parties, including financial information, intellectual property, and personal identification information. Security breaches and other disruptions could compromise our information, expose us to liability, and harm our reputation and business. The steps we take to deter and mitigate these risks may not be successful. We may not have the resources or technical sophistication to anticipate or prevent current or rapidly evolving types of cyber-attacks. Data and security breaches can also occur as a result of non-technical issues, including an intentional or inadvertent breach by our employees or by persons with whom we have commercial relationships. Federal, state, and foreign government bodies and agencies have adopted or are considering the adoption of laws and regulations regarding the collection, use, and disclosure of personal information obtained from customers and individuals. The costs of compliance with, and other burdens imposed by, such data privacy laws and regulations, including those of the European Union (“E.U.”) and the U.K. which are, in some respects, more stringent than U.S. standards, could be significant. Any compromise or breach of our security could result in a violation of applicable privacy and other laws, legal and financial exposure, negative impacts on our customers’ willingness to transact business with us, and a loss of confidence in our security measures, which could have an adverse effect on our results of operations and our reputation.

We are dependent upon key customers.

We could be adversely affected by changes in the business or financial condition of a customer or customers. A prolonged decrease in capital spending by our rail customers or decline in sales orders from other customers could negatively impact our sales and profitability. No assurances can be given that a significant downturn in the business or financial condition of a current customer, or customers, or potential litigation with a current customer, would not also impact our future results of operations and/or financial condition.

An adverse outcome in any pending or future litigation or pending or future warranty claims against the Company or its subsidiaries or our determination that a customer has a substantial product warranty claim could negatively impact our financial results and/or our financial condition.

We are party to various legal proceedings. In addition, from time to time our customers assert claims against us relating to the warranties which apply to products we have sold. There is the potential that an outcome adverse to us or our subsidiaries in pending or future legal proceedings or pending or future product warranty claims could materially exceed any accruals we have established and adversely affect our financial results and/or financial condition. In addition, we could suffer a significant loss of business from a customer who is dissatisfied with the resolution of a warranty claim.

A portion of our sales are derived from our international operations, which expose us to certain risks inherent in doing business on an international level.

Doing business outside the United States subjects the Company to various risks, including changing economic and political conditions, work stoppages, exchange controls, currency fluctuations, armed conflicts, and unexpected changes in U.S. and foreign laws relating to tariffs, trade restrictions, transportation regulations, foreign investments, and taxation. Increasing sales to foreign

10

countries, including Canada, China, India, Mexico, the U.K., and countries within the E.U., exposes the Company to increased risk of loss from foreign currency fluctuations and exchange controls as well as longer accounts receivable payment cycles. We have little control over most of these risks and may be unable to anticipate changes in international economic and political conditions and, therefore, unable to alter our business practices in time to avoid the adverse effect of any of these possible changes.

Changes in exchange rates for foreign currencies may reduce international demand for our products or increase our labor or supply costs in non-U.S. markets. Fluctuations in the relative values of the U.S. dollar, Canadian dollar, British pound, and Euro may result in volatile earnings to reflect exchange rate translation in our Canadian and European sales and operations. If the U.S. dollar strengthens in value as compared to the value of the Canadian dollar, British pound, or Euro, our reported earnings in dollars from sales in those currencies will be unfavorable. Conversely, a favorable result will be reported if the U.S. dollar weakens in value as compared to the value of the Canadian dollar, British pound, or Euro.

Economic conditions and regulatory changes caused by the United Kingdom’s exit from the European Union could adversely affect our business.

Pursuant to a June 2016 referendum, the U.K. left the E.U. on January 31, 2020, commonly referred to as “Brexit.” The U.K. government and the E.U. are operating under a transitional arrangement that expires on December 31, 2020, and the parties are working on the terms of a future relationship, including a potential trade agreement. The nature and terms of the future relationship between the U.K. and the E.U. remain subject to negotiation and uncertain. Additionally, Brexit could lead to legal uncertainties related to applicable laws and regulations that apply to our operations and as the U.K. determines which E.U. laws and regulations to adopt, replace, or disregard. There has been volatility in currency exchange rate fluctuations between the U.S. dollar relative to the British pound, which could continue. The withdrawal of the U.K. from the E.U. has also created market volatility and could continue to contribute to instability in global financial and foreign exchange markets, political institutions, and regulatory agencies as negotiations of trade deals between the U.K. and the E.U., and also between the U.K. and other countries, possibly including the U.S., occur during the transition period. Brexit is an unprecedented event, and, accordingly, it is unclear what long-term economic, financial, trade, and legal effects will result.

The majority of our U.K. operations are heavily concentrated within the U.K. borders; however, this could adversely affect the future growth of our U.K. operations into other European locations. Our U.K. operations represented approximately 9% and 11% of our total revenue for the years ended December 31, 2019 and 2018, respectively. During the years ended December 31, 2019 and 2018, less than 1% of our consolidated net revenue was from the U.K. operation’s sales exported to E.U. members other than the U.K.

Material modification to the North American Free Trade Agreement (“NAFTA”) and certain other international trade agreements could affect our business, financial condition, and results of operations.

The current Presidential administration has made comments suggesting it is not supportive of certain international trade agreements, including NAFTA. On November 30, 2018, the United States-Mexico-Canada Agreement (“USMCA”) was signed by the parties, and has been ratified by each country except Canada. At this time, it remains unclear what the current administration and Congress would or would not do with respect to these international trade agreements. Potential material modifications to NAFTA, or certain other international trade agreements, including USMCA, may have a material adverse effect on our business, financial condition, and results of operations.

Violations of foreign governmental regulations, including the U.S. Foreign Corrupt Practices Act and similar worldwide anti-corruption laws, could result in fines, penalties, and criminal sanctions against the Company, its officers, or both and could have a material and adverse effect on our business.

Our foreign operations are subject to governmental regulations in the countries in which we operate, as well as U.S. laws. These regulations include those related to currency conversion, repatriation of earnings, taxation of our earnings and the earnings of our personnel, and the increasing requirement in some countries to make greater use of local employees and suppliers, including, in some jurisdictions, mandates that provide for greater local participation in the ownership and control of certain local business assets.

The U.S. Foreign Corrupt Practices Act and other similar worldwide anti-corruption laws, such as the U.K. Bribery Act, prohibit improper payments for the purpose of obtaining or retaining business. Although we have established an internal control structure, corporate policies, compliance, and training processes to reduce the risk of violation, we cannot ensure that these procedures protect us from violations of such policies by our employees or agents. Failure to comply with applicable laws or regulations could subject us to fines, penalties, and suspension or debarment from contracting. Events of non-compliance could harm our reputation, reduce our revenues and profits, and subject us to criminal and civil enforcement actions. Violations of such laws or allegations of violation could disrupt our business and result in material adverse results to our operating results or future profitability.

Certain divisions of our business depend on a small number of suppliers. The loss of any such supplier could have a material and adverse effect on our business, financial condition, and result of operations.

In our Rail Products business unit, we rely on a limited number of suppliers for key products that we sell to our customers. In addition, our Piling division is predominantly dependent upon one supplier for sheet piling while our Protective Coatings division is predominately dependent on two suppliers of epoxy coating. A significant downturn in the business of one or more of these suppliers, a disruption in their manufacturing operations, an unwillingness to continue to sell to us, or a disruption in the availability of existing and new piling and rail products may adversely impact our financial results.

11

Fluctuations in the price, quality, and availability of the primary raw materials used in our business could have a material and adverse effect on our operations and profitability.

Many of our businesses utilize steel as a significant product component. The steel industry is cyclical and prices and availability are subject to these cycles, as well as to international market forces. We also use significant amounts of cement and aggregate in our Concrete Ties and Precast Concrete Products businesses. No assurances can be given that our financial results would not be adversely affected if prices or availability of these materials were to change in a significantly unfavorable manner.

Labor disputes may have a material and adverse effect on our operations and profitability.

Four of our manufacturing facilities are staffed by employees represented by labor unions. Approximately 111 employees employed at these facilities are currently working under three separate collective bargaining agreements. Disputes with regard to the terms of these agreements or our potential inability to renegotiate acceptable contracts with these unions could result in, among other things, strikes, work stoppages, slowdowns, or lockouts, which could cause a disruption of our operations and have a material and adverse effect on our results of operations, financial condition, and liquidity.

Actions of activist shareholders could be disruptive and potentially costly and the possibility that activist shareholders may seek changes that conflict with our strategic direction could cause uncertainty about the strategic direction of our business.

In February 2016, the Company entered into an agreement with an activist investor, Legion Partners Asset Management, LLC and various of its affiliates (collectively, “Legion Partners”) that had filed a Schedule 13D with the SEC with respect to the Company. This agreement expired by its terms on February 13, 2018, and Legion Partners remains a greater than 5% owner of Company stock.

Activist investors may attempt to effect changes in the Company’s strategic direction and how the Company is governed, or to acquire control over the Company. Some investors seek to increase short-term shareholder value by advocating corporate actions, such as financial restructuring, increased borrowing, special dividends, stock repurchases, or even sales of assets or the entire company. While the Company welcomes varying opinions from all shareholders, activist campaigns that contest or conflict with our strategic direction could have an adverse effect on the Company’s results of operations and financial condition, as responding to proxy contests and other actions by activist shareholders can disrupt our operations, be costly and time-consuming, and divert the attention of the Company’s board and senior management from the pursuit of business strategies. In addition, perceived uncertainties as to our future direction as a result of changes to the composition of our Board may lead to the perception of a change in the direction of the business, instability or lack of continuity, which may be exploited by our competitors, may cause concern to our current or potential customers, may result in the loss of potential business opportunities and may make it more difficult to attract and retain qualified personnel and business partners. These types of actions could cause significant fluctuations in our stock price based on temporary or speculative market perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of our business.

Our success is highly dependent on the continued service and availability of qualified personnel.

Much of our future success depends on the continued availability and service of key personnel, including our Chief Executive Officer, the executive team, and other highly skilled employees. Changes in demographics, training requirements, and the availability of qualified personnel could negatively affect our ability to compete and lead to a reduction in our profitability.

We may not foresee or be able to control certain events that could adversely affect our business.

Unexpected events, including fires or explosions at our facilities, natural disasters, armed conflicts, terrorism, health epidemics or pandemics, economic or political uncertainties or instability, civil unrest, strikes, unplanned outages, equipment failures, failure to meet product specifications, or disruptions in certain areas of our operations, may cause our operating costs to increase or otherwise negatively impact our financial performance.

Shifting federal, state, local, and foreign regulatory policies impose risks to our operations.

We are subject to regulation by federal, state, local, and foreign regulatory agencies and are therefore subject to a variety of legal proceedings and compliance risks, including those described in Item 3 - Legal Proceedings and in Part II, Item 8, Financial Statements and Supplementary Data, Note 18 to the Consolidated Financial Statements, contained in this Annual Report on Form 10-K. Like other companies engaged in environmentally sensitive businesses, we are required to comply with numerous laws and regulations, including environmental matters relating to, among other things, the treatment, disposal, and storage of wastes, investigation and remediation of contaminated soil and groundwater, the discharge of effluent into waterways, and the emissions of substances into the air. We are required to obtain various authorizations, permits, approvals, and certificates from governmental agencies. The Company could be subject to liability with respect to remediation of past contamination in the operation of some of its current and former facilities and remediation of contamination by former owners or operators of the Company’s current or former facilities. Compliance with emerging regulatory initiatives, delays, discontinuations, or reversals of existing regulatory policies in the markets in which we operate, including costs associated with any required environmental remediation and monitoring, could have an adverse effect on our business, results of operations, cash flows, and financial condition.

A substantial portion of our operations is heavily dependent on governmental funding of infrastructure projects. Many of these projects have “Buy America” or “Buy American” provisions. Significant changes in the level of government funding of these projects could have a favorable or unfavorable impact on our operating results. Additionally, government actions concerning “Buy America” provisions, taxation, tariffs, the environment, or other matters could impact our operating results.

PART II

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITY SECURITIES

(Dollars in thousands, except share data unless otherwise noted)

Stock Market Information

The Company had 302 common shareholders of record on February 19, 2020. Common stock prices are quoted daily through the NASDAQ Global Select Market quotation service (Symbol: FSTR).

Dividends

During 2019 and 2018, the Company did not declare any quarterly dividends.

The Company’s April 30, 2019 credit facility permits it to pay dividends and distributions and to make redemptions with respect to its stock providing no event of default or potential default (as defined in the facility agreement) has occurred prior to or after giving effect to the dividend, distribution, or redemption.

Securities Authorized for Issuance Under Equity Compensation Plans

Under the 2006 Omnibus Incentive Plan, from May 2006 through May 2017, non-employee directors were automatically awarded fully-vested shares of the Company’s common stock as determined by the Board of Directors at each annual shareholder meeting at which such non-employee director is elected or re-elected. Since May 2018, the non-employee directors have received annual awards of forfeitable restricted shares subject to a one-year vesting requirement. During 2019, pursuant to the 2006 Omnibus Incentive Plan, the Company issued approximately 22,000 shares of the Company’s common stock for the annual non-employee director equity award, which shares vest on the one-year anniversary of the date of grant. During 2019, there were no non-employee directors who elected the option to receive fully-vested shares of the Company’s common stock in lieu of director cash compensation. Through December 31, 2019, there were approximately 206,000 fully vested shares issued under the 2006 Omnibus Incentive Plan to non-employee directors. During the quarter ended June 30, 2017, the Nomination and Governance Committee and Board of Directors jointly approved the Deferred Compensation Plan for Non-Employee Directors under the 2006 Omnibus Incentive Plan, which permits non-employee directors of the Company to defer receipt of earned cash and/or stock compensation for service on the Board. As of December 31, 2019, approximately 54,000 deferred share units were allotted to the accounts of non-employee directors pursuant to the Deferred Compensation Plan for Non-Employee Directors.

The Company grants eligible employees restricted stock and performance unit awards under the 2006 Incentive Omnibus Plan. The forfeitable restricted stock awards granted prior to March 2015 generally time-vest after a four-year period, and those granted after March 2015 generally time-vest ratably over a three-year period, unless indicated otherwise in the underlying restricted stock award agreement. Performance unit awards are offered annually under separate three-year long-term incentive programs. Performance 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.

With respect to awards made prior to December 31, 2016, the Company will withhold or employees may tender shares of restricted stock when issued to pay for withholding taxes. Since 2017, the Company has withheld shares of restricted stock for satisfaction of tax withholding obligations. During 2019 and 2018, the Company withheld 34,198 and 11,445 shares, respectively, for this purpose. The values of the shares withheld were $621 and $316 in 2019 and 2018, respectively.

Issuer Purchases of Equity Securities

The Company’s purchases of equity securities for the three months ended December 31, 2019 were as follows:

	Total number of shares purchased (1)	Average price paid per share		Total number of shares purchased as part of publicly announced plans or programs	Approximate dollar value of shares that may yet be purchased under the plans or programs

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

(Dollars in thousands, except share data unless otherwise noted)

Executive Level Overview

2019 Developments and 2020 Outlook

During 2019:

•Net sales increased by $28,088, or 4.5%, to $655,057;

•New orders^(a) decreased by 2.5%; however, backlog^(a) of $230,067 was a 4.4% increase over the prior year end;

•The Company generated net income of $42,568, or $4.00 per diluted share;

•We reversed a valuation allowance of $29,648 on our U.S. deferred tax assets;

•The Company reported adjusted EBITDA (earnings before interest, taxes, depreciation, amortization, and certain expenses) of $45,642; ^(b)

•We effectively managed working capital levels, resulting in $29,297 of net cash provided by operating activities;

•We reduced borrowings by $16,789, or 22.4%, to 58,193, resulting in net debt $44,015; ^(b)

•The Company successfully implemented cost containment programs resulting in a 60 basis point decline year over year in selling and administrative expense as a percent of sales;

•Our credit agreement was amended from a maximum capacity of $195,000 to $165,000, including a term loan of $25,000;

•We announced and commenced the relocation of the CXT Concrete Buildings facility in Spokane, WA to Boise, ID, which was complete in the first quarter of 2020; and

•The Company concluded U.S. pension settlements which resulted in a $2,210 non-cash expense.

^(a) The Company defines new orders as a contractual agreement between the Company and a third-party in which the Company will, or has the ability to, satisfy the performance obligations of the promised products or services under the terms of the agreement. The Company defines backlog as contractual commitments to customers for which the Company’s performance obligations have not been met, including with respect to new orders and contracts for which the Company has not begun any performance. Management utilizes new orders and backlog to evaluate the health of the industries in which the Company operates, the Company’s current and future results of operations and financial prospects, and strategies for business development. The Company believes that new orders and backlog are useful to investors as supplemental metrics by which to measure the Company’s current performance and prospective results of operations and financial performance.

^(b) The following tables display reconciliations of non-GAAP financial measures for the years ended December 31, 2019 and 2018. EBITDA is a financial metric utilized by management to evaluate the Company’s performance on a comparable basis. The Company believes that EBITDA is useful to investors as a supplemental way to evaluate the ongoing operations of the Company’s business as EBITDA enhances investors’ ability to compare historical periods as it adjusts for the impact of financing methods, tax law and strategy changes, and depreciation and amortization. In addition, EBITDA is a financial measurement that management and the Company’s Board of Directors use in their financial and operational decision-making and in the determination of certain compensation programs. Adjusted EBITDA includes certain adjustments to EBITDA. In 2019, the Company made adjustments to exclude the impact of the U.S. defined benefit plan settlements, costs associated with relocation and closure activities, including nonoperational start-up costs related to the Boise, ID facility. In 2018, the Company made adjustments to exclude the impact of the Union Pacific Railroad Concrete Tie Settlement. The Company views net debt, which is total debt less cash and cash equivalents, as an important metric of the operational and financial health of the organization and useful to investors as an indicator of our ability to incur additional debt and to service our existing debt. Non-GAAP financial measures are not a substitute for GAAP financial results and should only be considered in conjunction with the Company’s financial information that is presented in accordance with GAAP. Quantitative reconciliations of EBITDA and debt to the non-GAAP financial measures are presented below.

	Year Ended December 31,

The Company entered 2019 with a solid starting backlog that was coupled with sustained, but uneven at times, order activity throughout the year, which led to each of our three segments exceeding their prior year sales totals. This facilitated our year over year increase in operating results while still being able to maintain a strong backlog as we enter 2020. While sales and gross profit increased over the prior year, the Company’s gross profit margins were unfavorably impacted by weakness in our energy market test and inspection services, operational execution in piling distribution, as well as product mix dilution by increased contributions from our lower margin distribution product lines. We were able to continue our containment of selling and administrative expenses, which were reduced on a percent of sales basis. Our operating teams were able to successfully manage working capital levels while sales increased over the prior year. The operating cash generated allowed us to continue to reduce our outstanding debt as well as improve our leverage ratio throughout the year. This in turn provided us the flexibility in our capital deployment strategies to enhance and expand our operations as we look forward.

In 2019, our Rail Products and Services segment reported increased sales in our North American markets when compared to the prior year. The North American transit market primarily supported our sales growth, as demand for expansion projects aimed at congested cities remained strong during the year, despite timing delays. This trend was reinforced during the fourth quarter with two significant transit projects being secured. With rail transit spending significantly up over the prior year, we continued to see transit operators investing in infrastructure with the expansion and modernization of existing operations across both North America and Europe. The North American transit networks were favorably impacted by funding for capacity expansion as ridership levels on a macro basis increased. Conversely, our sales in Europe decreased in 2019, as service work related to the London Crossrail transit system project has been reduced as we began to near the completion of the project. We have expanded our service team in the U.K. to meet the requirements of these major projects for the London Underground rail and other significant modernization projects. Much of this work is directed to on-track services for the integration of driver automation, passenger information systems, access control, and security system interface.

Our friction management products and services also contributed to the year over year sales growth. The Company continues to target and advance products and solutions to help improve safety and operating efficiency as well as introduce services that contribute to extending the useful life of certain rail equipment and lowering maintenance costs for operators. As friction management becomes increasingly important to freight railroads as operators see the demonstrated savings and reduced wear and tear, our initiatives around growth and service contracts for friction management are continuing to move forward. Our on-track services in the United States continued to expand during 2019, providing installation, maintenance, monitoring, and inspection of our on-track products.

During the second half of 2019, the United States freight rail market showed signs of weakness, with carriers reporting declining commodity carload volume. This was driven by an overall manufacturing economic slowdown, unfavorable conditions in agriculture, continuing decline in coal, and reduced intermodal shipments. While the segment was not significantly impacted by this slowdown during 2019, we will continue to monitor this market in 2020. With steel prices relatively stable during the year, our pricing exposures were minimized compared to what we would expect to see in more volatile market conditions.

The segment continued to focus on maintaining a tight cost structure and maximizing profitability, which was evidenced by the increased gross profit margins. We believe our current structure in our Rail Products and Services segment resulted in positive results in 2019 and has positioned us for continued growth in 2020, supported by a strong ending backlog and plans to expand our served markets.

Year over year improvement in the Tubular and Energy Services segment was driven by the midstream markets we serve that include our Protective Coatings and Measurement Systems offerings for pipelines. We benefited from the market investments being targeted at increasing pipeline capacity needed for continued oil and gas production growth in the United States shale territories. These projects require many miles of pipe and multiple metering systems along the way.

Our upstream energy market weakened during 2019, with sales declining in Test, Inspection, and Threading Services from the prior year. Our services in this particular market felt the most significant headwinds as a result of cutbacks in new rig deployments, tariffs and quotas that impacted our volume from foreign pipe sources, and other supply chain pressures resulting from customer cost cutting actions that reduced sales of our provided services. With energy well economics driving decisions, we believe that it is critical to be focused on the most profitable locations. We continued to analyze our efficiency and operating footprint and take action to address this need by expanding our service offerings in the Permian region as well as redeploying operations to Wyoming to react to the shift in demand in that region. Additionally, we ceased operating activities during 2019 at three separate locations in the Gulf coast and lower midcontinent regions in response to this shifting demand. Management continues to prioritize efforts to improve profitability of our upstream services while maintaining the success we have seen in our midstream offerings.

Our Construction Products segment reported favorable results during 2019, which included increased sales, gross profit, and segment profit, excluding relocation and closure costs, compared to the prior year. Sales were supported by each of the businesses within the segment, as Piling capitalized on the Port Everglades project, Fabricated Bridge was able to secure a significant number of small and midsize jobs that provided higher margin returns, and Precast Concrete Products saw increased demand at each of its regions.

During 2019, our Piling division sales exceeded prior year levels as we entered the year with a very strong backlog that included the Port Everglades project. The profitability of the division was challenged as cost overages from project scope adjustments, product rework, and supply chain inefficiencies were absorbed by the Company and reduced the profit margins considerably. Management has enacted programs, including establishing additional yards, to alleviate supply chain disruptions by creating more efficient ways for our products to reach the end customer in the anticipated manner. Our Fabricated Bridge division was able to secure a high volume of small to midsize projects during the year which led to increased sales and profitability when compared to the prior year. While these types of projects are generally highly competitive and produce lower margins, the division was able to surpass the prior year in both gross profit and gross profit margin. Management continues to believe that neither the dynamics of our served market nor the number of structurally deficient, obsolete bridges have changed in a meaningful way. We have identified a number of large projects being planned for both the near and long term that support the need for the infrastructure restoration.

The Precast Concrete Products business unit increased its 2019 sales when compared to the prior year, primarily through precast building sales to various county and municipal agencies. The business was able to capitalize on the recent expansion of one of its facilities, through which the business was able to grow its market reach as well as increase its product offerings. The business was also able to capitalize on programs focused on creating and maintaining operating efficiencies that were implemented due to unfavorable production costs and an unexpected interruption in the prior year. This resulted in a significant improvement in gross profit margin for the business. During the fourth quarter, the Company announced and commenced the plan to close the Precast Concrete Products facility in Spokane, WA and relocate this operation to Boise, ID, which was complete during the first quarter of 2020. This relocation is part of an initiative focusing on regional growth opportunities and logistical savings associated with a more centralized location closer to the Company’s existing and prospective customer base.

Our management team has done an exceptional job focusing on cost control as we continued to grow for the third consecutive year. Management intends to stay focused on prudent working capital management and operating cash flow. We believe that the Company’s expenses and operating leverage now provide the agility needed to succeed in the cyclical markets in which we participate. Our long-term objective is to continue the modernization of the entire Company with the ongoing integration of our enterprise resource program system from which we can grow and leverage best in class business processes.

Fiscal 2019 Compared to Fiscal 2018 — Company Analysis

Net sales of $655,057 for the year ended December 31, 2019 increased by $28,088, or 4.5%, compared to the prior year. Each of our three reporting segments contributed to the increase, with Construction Products increasing by 15.0%, Tubular and Energy Services increasing by 1.3%, and Rail Products and Services increasing by 0.7% over the prior year.

Gross profit increased by $4,213 over the prior year to $121,372 for 2019. This increase was attributable to each of our segments, with Construction Products increasing by $2,602, Rail Products and Services increasing by $1,360, and Tubular and Energy Services increasing by $251. While gross profit increased, gross profit margin for 2019 was 18.5%, or 20 basis points (“bps”) lower than the prior year. The current year margin was primarily impacted by excess operational execution costs incurred, decreased volume in our upstream energy services, and the dilutive effect of our increased volume contributions from our lower margin distribution businesses.

Selling and administrative expenses increased by $307, or 0.4%, over the prior year. The increase was primarily attributable to increases in bad debt allowance expenses of $1,395 over the prior year, costs related to the continuing implementation of our ERP system of $1,197, third-party services, including insurance services, of $976, and personnel-related costs of $906 compared to the prior year. These increases were partially offset by a reduction of legal fees related to the Union Pacific Railroad (“UPRR”) Concrete Tie Settlement of $4,485 when compared to the prior year. As a result of our continuing cost containment programs, selling and administrative expenses were reduced by 60 bps as a percentage of net sales as compared to the prior year.

For the year ended December 31, 2019, the Company recorded an expense of $3,484 related to relocation and closure activities and an expense of $2,210 related to U.S. pension settlements within “Other expense (income) - net.” Interest expense, net of interest income, for the year ended December 31, 2019 was reduced by $1,234 as a result of the $16,789 reduction in outstanding debt as well as the more favorable interest rate terms within our April 30, 2019 amended credit agreement.

The Company’s effective income tax rate for 2019 was (144.7)%, compared to (16.7)% in the prior year period. During 2019, the Company reversed $29,648 of its valuation allowance previously recorded against U.S. deferred tax assets. The positive evidence considered in evaluating U.S. deferred tax assets included cumulative financial income over the three-year period ended December 31, 2019, as well as the composition and reversal patterns of existing taxable and deductible temporary differences between financial reporting and tax. Based on our evaluation, the Company believed it was appropriate to rely on forecasted future taxable income to support its U.S. deferred tax assets. The amount of deferred tax assets considered to be realizable, however, could be adjusted if negative evidence outweighs additional subjective evidence such as our projections for growth. In 2018, the Company’s effective tax rate was significantly affected by an increase to our domestic valuation allowance against deferred tax assets resulting from the effects of the Concrete Tie Settlement.

Net income for the year ended December 31, 2019 was $42,568, or $4.00 per diluted share, compared to net loss for the 2018 period of $31,168, or $3.01 loss per diluted share.

Results of Operations — Segment Analysis

Our Rail Products and Services segment sales increased by $2,284, or 0.7%, compared to the prior year. The increase was attributable to our Rail Products business unit, which grew by $5,874 and was partially offset by a decline of $3,590 in our Rail Technologies business unit. The Rail Products increase was primarily attributable to growth the domestic transit market. We saw demand in this area as investments are being made in expansion projects to address commuter demand in congested cities. Also contributing to the growth in Rail Products were increased sales volume of new rail and insulated joint product offerings. The reduction in Rail Technologies sales was primarily attributable to the reduced activity level of the London Crossrail project, as it nears its completion.

Segment gross profit increased by $1,360, or 2.2%, which was driven by an increase in our Rail Products business unit and was partially offset by a reduction in Rail Technologies gross profit. Segment gross profit margin increased by 30 bps principally attributable to our insulated rail joint and related track accessory offerings within Rail Products and, to a lesser extent, our domestic Rail Technologies friction management operations. Additionally, gross profit in 2018 was unfavorably impacted by a charge of $611 within our Rail Technologies business unit related to a commercial decision to support a customer concern for an automation project. The Rail Products and Services segment profit for 2019 was $19,641, a segment profit margin of 6.1%, compared to $19,468, and a margin of 6.1% for 2018. Segment profit for 2019 included an increase in realized foreign exchange expense of $685 when compared

19

to the prior year. The 2018 segment profit included an expense of $169 related to diligence activities from a business opportunity to expand our technological offerings that did not materialize.

During 2019, the new orders within the Rail Products and Services segment decreased by 5.2% when compared to the prior year. Each of the business units within the segment had decreases in new orders compared to 2018. Despite the decline in new orders, backlog increased by 6.4% compared to the prior year, ending 2019 at $103,694. The increase in backlog was driven by significant fourth quarter 2019 order activity from domestic transit authorities within our Rail Products business unit.

Construction Products

	Year Ended December 31,						Increase/(Decrease)			Percent Increase/(Decrease)
	2019			2018			2019 vs. 2018			2019 vs. 2018
Net Sales	$	182,486		$	158,653		$	23,833		15.0	%
Gross Profit	$	25,501		$	22,899		$	2,602		11.4	%

Segment Profit Percentage	3.1		%	4.3		%	(1.1)		%	(26.8)	%

Our Construction Products segment sales increased $23,833, or 15.0%, compared to the prior year, which was attributable to each of our business units within the segment. Precast Concrete Products experienced a sales increase of 21.3%, primarily within building sales, driven by orders from county and municipal agencies. The Fabricated Bridge sales increase was primarily driven by our ability to secure small and midsize orders while a significantly large project did not materialize. Our favorable Piling sales results included the Port Everglades project, with the order being secured in 2018 and fulfilled during 2019.

The Construction Products segment gross profit increased by $2,602, or 11.4%, compared to the prior year. The gross profit increase was primarily due to sales volume within our Precast Concrete Products and Fabricated Bridge offerings. The gross profit and gross profit margin were unfavorably impacted by increased project costs from scope adjustments, product rework, and supply chain inefficiencies incurred within our Piling distribution lines. The segment profit of $5,726 decreased by $1,072 compared to the prior year to 3.1% of net sales. Included within segment profit for 2019 are relocation and closure costs of $1,768 related to our closure of the Spokane, WA concrete building facility and subsequent relocation of operations to Boise, ID, which was completed during the first quarter of 2020. This relocation is part of an initiative focusing on regional growth opportunities and logistical saving associated with a more centralized location closer to the Company’s existing and prospective customer base.

For 2019, the Construction Products segment had a 3.1% decrease in new orders compared to the prior year period. This decrease was attributable to Piling as a project comparable to the 2018 Port Everglades order was not secured during the 2019 period. The segment’s backlog as of December 31, 2019 was $92,280, a 3.3% decrease compared to the prior year end.

Tubular and Energy Services

	Year Ended December 31,						Increase/(Decrease)			Percent Increase/(Decrease)
	2019			2018			2019 vs. 2018			2019 vs. 2018
Net Sales	$	150,763		$	148,792		$	1,971		1.3	%
Gross Profit	$	32,204		$	31,953		$	251		0.8	%
Gross Profit Percentage	21.4		%	21.5		%	(0.1)		%	(0.5)	%
Segment Profit	$	11,147		$	12,647		$	(1,500)		(11.9)	%
Segment Profit Percentage	7.4		%	8.5		%	(1.1)		%	(13.0)	%

Our Tubular and Energy Services segment sales increased by $1,971, or 1.3%, compared to the prior year. The increase was supported by our Protective Coatings and Measurement Systems business unit. The increase in demand for midstream infrastructure led to a 12.1% increase in Protective Coatings and Measurement Systems sales. The increase was partially offset by a reduction of sales of 14.7% in our Test, Inspection, and Threading Services business unit as weakness in the upstream energy market led to a decline in demand for our provided services.

Tubular and Energy Services gross profit increased by $251, which was favorably impacted by both sales volume and improved margins within Protective Coatings and Measurement Systems business. The increase was partially offset by a reduction in our Test, Inspection, and Threading Services gross profit, which was caused by the decreased sales volume. The segment profit decreased to $11,147, or 7.4% of net sales, in 2019 compared to $12,647, or 8.5% of net sales, in 2018. Included in 2019 segment profit are closure costs of $1,716 related to three separate site closings during the year and an increase in bad debt expense of $610. In 2018, segment profit was negatively impacted by the sale of a 54.5 acre greenfield plot of land which resulted in a $269 loss, a $786 loss on the sale or disposal of multiple fixed assets, and expenses of $586 related to a site closure as management positions the segment away from non-core assets.

20

The Tubular and Energy Services segment had an increase in new orders of 4.6% compared to the prior year period. The increase in new orders during 2019 was due to the demand created by midstream energy markets continuing to invest in their infrastructure, which favorably impacted our Protective Coating and Measurement Systems business unit operating results. The increase in new orders, specifically during the fourth quarter, led to a 23.7% increase in backlog, with a December 31, 2019 balance of $34,093.

Liquidity and Capital Resources

Total debt as of December 31, 2019 and 2018 was $58,193 and $74,982, respectively, and was primarily comprised of borrowings on the revolving credit facility and our term loan. Our need for liquidity relates primarily to working capital requirements for operating activities, debt service payments, and capital expenditures.

The change in cash and cash equivalents for the years ended December 31, 2019 and 2018 were as follows:

	Year Ended December 31,
	2019		2018
Net cash provided by operating activities	$	29,297	$	25,964
Net cash (used in) provided by investing activities	(7,680)		2,248
Net cash used in financing activities	(18,246)		(55,300)
Effect of exchange rate changes on cash and cash equivalents	525		(308)
Net increase (decrease) in cash and cash equivalents	$	3,896	$	(27,396)

Cash Flows from Operating Activities

During the year ended December 31, 2019, net cash provided by operating activities was $29,297 compared to $25,964 during the prior year period. For the year ended December 31, 2019, income and adjustments to income from operating activities provided $37,229 compared to $34,367 in 2018. Working capital and other assets and liabilities used $7,932 in the current period compared to $8,403 during 2018. During the year ended December 31, 2019, the Company made payments of $10,000 related to the UPRR Concrete Tie Settlement.

The Company’s calculation of days sales outstanding was 49 days as of December 31, 2019 compared to 50 days as of December 31, 2018. We believe our receivables portfolio is strong.

Cash Flows from Investing Activities

For the year ended December 31, 2019, the Company had capital expenditures of $8,831, a $3,580 increase from 2018. The current year expenditures were primarily related to plant expansion and automation integration programs within our Tubular and Energy Services segment, the purchase of a continuous welded rail car and unloader within our Rail Products and Services segment, and general plant and operational improvements. The capital expenditures during 2018 related to general plant and operational improvements. The Company received proceeds of $1,151 from the sale of assets during the year ended December 31, 2019 compared to $2,389 in 2018. The current year proceeds were primarily attributable to the sale of land and improvements in Castle Rock, CO. The 2018 proceeds were primarily from the sale of a greenfield site in Willis, TX in the Tubular and Energy Services segment. On August 1, 2018, the Company executed the sale of its 45% ownership in L B Pipe and Couplings Products, LLC (“L B Pipe JV”), which provided $3,875 and $1,235 from the sale of its ownership interest and repayment of revolving line of credit from L B Pipe JV, respectively.

Cash Flows from Financing Activities

The Company reduced its outstanding debt by $16,789 during the year ended December 31, 2019 primarily from operational cash flows and proceeds from the sale of non-core assets. During the year ended December 31, 2018, the Company reduced outstanding debt by $54,984, primarily from international excess cash repatriation, proceeds from the sale of non-core assets, and operational cash flows. The Company paid $836 in financing fees related to our 2019 amended credit facility agreement.

Financial Condition

The Company generated $29,297 from cash flows from operations during 2019 that was utilized to make payments against our revolving credit facility and fund capital expenditures. As of December 31, 2019, we had $14,178 in cash and cash equivalents and $105,640 of availability under the Third Amended and Restated Credit Agreement while carrying $58,193 in total debt. We believe this liquidity will provide adequate flexibility to operate the business in a prudent manner, continue to service our revolving credit facility, and be better leveraged to weather any future downturn in our markets.

Non-domestic cash balances of $13,660 are held in various locations throughout the world. Management determined that should the cash balances of our Canadian and U.K. subsidiaries exceed our projected capital needs, excess funds will continue to be repatriated. There were no such repatriations of excess cash during 2019.

On April 30, 2019, the Company, its domestic subsidiaries, and certain of its Canadian and European subsidiaries (collectively, the “Borrowers”), entered into the Third Amended and Restated Credit Agreement (“Amended 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. This Amended Credit

21

Agreement modifies the prior revolving credit facility, which had a maximum credit line of $195,000 and extends the maturity date from March 13, 2020 to April 30, 2024. The Amended Credit Agreement provides for a five-year, revolving credit facility that permits aggregate borrowings of the Borrowers up to $140,000 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. The Amended 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 and provides for additional term loan borrowings of up to $25,000 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 Amended 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 their domestic subsidiaries, have been pledged to the lenders as collateral for the lending obligations.

Borrowings under the Amended Credit Agreement bear interest at rates based upon either the base rate or Euro-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 Amended 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 Amended Credit Agreement). The base rate and Euro-rate spreads range from 25 to 125 basis points and 125 to 225 basis points, respectively.

The Amended Credit Agreement includes three 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, as defined in the Amended Credit Agreement, and (ii) 3.50 to 1.00 for all testing periods 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, as defined in the Amended Credit Agreement, which must be a minimum of 1.25 to 1.00; and (c) Minimum Working Capital to Revolving Facility Usage Ratio, defined as the sum of the inventory and accounts receivable of the Borrowers and certain other Guarantors divided by the Revolving Facility Usage, as defined in the Amended Credit Agreement, which must be a minimum of 1.40 to 1.00.

As of December 31, 2019, the Company was in compliance with the covenants in the Amended Credit Agreement.

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 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 December 31, 2019, the swap liability was $480, and as of December 31, 2018, the swap asset was $675. The Company continues to monitor the impact of the dissolution of LIBOR and its effect on our LIBOR-based interest rate swaps.

For a discussion of the terms and availability of the Company’s credit facilities, please see Part II, Item 8, Financial Statements and Supplementary Data, Note 10 of the Notes to Consolidated Financial Statements contained in this Annual Report on Form 10-K.

3.Further detail on the UPRR Concrete Tie Settlement is disclosed in Note 18 to Consolidated Financial Statements included in Part II, Item 8, Financial Statements and Supplementary Data of this report.

Other long-term liabilities include items such as deferred income taxes which are not contractual obligations by nature. The Company cannot estimate the settlement years for these items and has excluded them from the above table.

Management believes its internal and external sources of funds are adequate to meet anticipated needs, including those disclosed above, for the foreseeable future.

Off-Balance Sheet Arrangements

The Company’s off-balance sheet arrangements include the purchase obligations and standby letters of credit disclosed within the contractual obligations table above in the “Liquidity and Capital Resources” section. These arrangements provide the Company with increased flexibility relative to the utilization and investment of cash resources.

Backlog

Although backlog is not necessarily indicative of future operating results, the following table provides the backlog by business segment:

	December 31,
	2019		2018
Rail Products and Services	$	103,694	$	97,447
Construction Products	92,280		95,419
Tubular and Energy Services	34,093		27,552
Total backlog	$	230,067	$	220,418

While a considerable portion of our business is backlog driven, certain businesses, including the Test, Inspection, and Threading Services and the Rail Technologies business units, are not driven by backlog and therefore have insignificant levels of backlog throughout the year.

Critical Accounting Policies and Estimates

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States. The preparation of the consolidated financial statements requires management to make estimates and judgments that affect the reported amount of assets, liabilities, revenues, and expenses, and the related disclosure of contingent assets and liabilities. The following critical accounting policies, which are reviewed by the Company’s Audit Committee of the Board of Directors, relate to the Company’s more significant estimates and judgments used in the preparation of its consolidated financial statements. Actual results could differ from those estimates.

For a summary of the Company’s significant accounting policies, see Part II, Item 8, Financial Statements and Supplementary Data, Note 1 to the Consolidated Financial Statements, which is incorporated by reference into this Item 7.

Income Taxes - The recognition of deferred tax assets requires management to make judgments regarding the future realization of these assets. As prescribed by ASC 740, “Income Taxes,” valuation allowances must be provided for those deferred tax assets for which it is more likely than not (a likelihood of more than 50%) that some portion or all of the deferred tax assets will not be realized. This guidance requires management to evaluate positive and negative evidence regarding the recoverability of deferred tax assets. The determination of whether the positive evidence outweighs the negative evidence and quantification of the valuation allowance requires management to make estimates and judgments of future financial results.

The Company evaluates all tax positions taken on its federal, state, and foreign tax filings to determine if the position is more likely than not to be sustained upon examination. For positions that meet the more likely than not to be sustained criteria, the largest amount of benefit to be realized upon ultimate settlement is determined on a cumulative probability basis. A previously recognized tax position is derecognized when it is subsequently determined that a tax position no longer meets the more likely than not threshold to be sustained. The evaluation of the sustainability of a tax position and the expected tax benefit is based on judgment, historical experience, and other assumptions. Actual results could differ from those estimates upon subsequent resolution of identified matters.

The Company’s income tax rate is significantly affected by the tax rate on global operations. In addition to local country tax laws and regulations, this rate depends on the extent earnings are indefinitely reinvested outside the United States. Indefinite reinvestment is determined by management’s judgment about and intentions concerning the future operations of the Company.

Refer to Part II, Item 8, Financial Statements and Supplementary Data, Note 14 which is incorporated by reference into this Item 7, for additional information regarding the Company’s deferred tax assets. The Company’s ability to realize these tax benefits may affect the Company’s reported income tax expense and net income.

23

Revenue Recognition - We account for revenue in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 606, “Revenue from Contracts with Customers,” whereby the unit of account is a performance obligation. The majority of the Company’s revenue is from products transferred and services rendered to customers at a point in time. The Company recognizes revenue at the point in time at which the customer obtains control of the product or service, which is generally when 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 its physical location.

The Company also derives revenue from products and services provided under long-term agreements with its customers. The transaction price of a long-term agreement is allocated to each distinct performance obligation. The majority of the Company’s long-term contracts have a single performance obligation as the promise to transfer products or services is not separately identifiable from other promises in the contract and, therefore, not distinct. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or providing services.

The Company’s performance obligations under long-term agreements with its customers are generally satisfied as over time. 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. 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. Contract assets from over time contracts are recorded in “Inventories - net” within the Consolidated Balance Sheets and contract liabilities from over time contracts are recorded in “Deferred revenue” within the Consolidated Balance Sheets.

Accounting for these long-term agreements involves the use of various techniques to estimate total revenues and costs. The Company estimates profit on these long-term agreements as the difference between total estimated revenues and expected costs to complete a contract and recognizes that profit over the life of the contract. Contract estimates are based on various assumptions to project the outcome of future events that may span several years. These assumptions include, among other things, labor productivity, cost and availability of materials, and timing of funding by customers. The nature of these long-term agreements may give rise to several types of variable considerations, such as claims, awards, and incentive fees. Historically, these amounts of variable consideration have not been considered significant. Contract estimates may include additional revenue for submitted contract modifications if there exists an enforceable right to the modification, the amount can be reasonably estimated, and its realization is probable. These estimates are based on historical collection experience, anticipated performance, and the Company’s best judgment at that time. These amounts are generally included in the contract’s transaction price and are allocated over the remaining performance obligations. As significant changes in the above estimates could impact the timing and amount of revenue and profitability of our long-term contracts, we review and update contract-related estimates regularly. In the event a contract loss becomes known, the entire amount of the estimated loss is recognized in the Consolidated Statements of Operations.

See Part II, Item 8, Financial Statements and Supplementary Data, Note 3 to the Consolidated Financial Statements, which is incorporated by reference into this Item 7.

Goodwill - Goodwill is the cost of an acquisition less the fair value of the identifiable net assets of the acquired business. Goodwill is required to be tested for impairment at least annually. The Company performs its annual impairment test in the fourth quarter, or whenever events or changes in circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount.

The Company may first consider qualitative factors to assess whether there are indicators that it is more likely than not that the fair value of a reporting unit may not exceed its carrying amount. The quantitative goodwill impairment analysis involves comparing the fair value of a reporting unit to its carrying value, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss equal to the excess amount up to the goodwill balance is recorded as an impairment to goodwill of the reporting unit. The Company uses a combination of a discounted cash flow method and a market approach to determine the fair values of the reporting units.

A number of significant assumptions and estimates are involved in the estimation of the fair value of reporting units, including the identification of macroeconomic conditions, industry and market considerations, cost factors, and overall financial performance. The estimated fair value of a reporting unit is sensitive to changes in assumptions, including forecasted future operating cash flows, weighted-average cost of capital, terminal growth rates, and industry multiples.

The Company considers historical experience and available information at the time the fair values of its reporting units are estimated. The Company believes the estimates and assumptions used in estimating the fair value of its reporting units are reasonable and appropriate; however, different assumptions and estimates could materially impact the estimated fair value of its reporting units and the resulting determinations about goodwill impairment. This could materially impact the Company’s Consolidated Statements of Operations and Consolidated Balance Sheets. Future estimates may differ materially from current estimates and assumptions.

Additional information concerning the impairments is set forth in Part II, Item 8, Financial Statements and Supplementary Data, Note 4 to the Consolidated Financial Statements included herein, which is incorporated by reference into this Item 7.

24

Intangible Assets and Long-Lived Assets - The Company tests intangible assets and long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset or asset group may not be recoverable. Recoverability of assets is determined by comparing the estimated undiscounted future cash flows of the asset or asset group to their carrying amount. If the carrying value of the assets exceeds their estimated undiscounted future cash flows, an impairment loss would be determined as the difference between the fair value of the assets and its carrying value. Typically, the fair value of the assets would be determined using a discounted cash flow model which would be sensitive to judgments of what constitutes an asset group and certain assumptions such as estimated future financial performance, discount rates, and other assumptions that marketplace participants would use in their estimates of fair value. The accounting estimate related to asset impairments is highly susceptible to change from period to period because it requires management to make assumptions about the existence of impairment indicators and cash flows over future years. These assumptions impact the amount of an impairment, which would have an impact on the Consolidated Statements of Operations.

Additional information concerning the impairments is set forth in Part II, Item 8, Financial Statements and Supplementary Data, Note 4 to the Consolidated Financial Statements included herein, which is incorporated by reference into this Item 7.

New Accounting Pronouncements - See Part II, Item 8, Financial Statements and Supplementary Data, Note 1 to the Consolidated Financial Statements, included herein for information regarding new accounting pronouncements.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of L.B. Foster Company and Subsidiaries

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of L.B. Foster Company and Subsidiaries (the Company) as of December 31, 2019 and 2018, the related consolidated statements of operations, comprehensive (loss) income, stockholders’ equity and cash flows for each of the two years in the period ended December 31, 2019, and the related notes and financial statement schedule listed in the Index at Item 15 (a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2019, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 27, 2020 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

L.B. FOSTER COMPANY AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in thousands, except share data unless otherwise noted)

Note 1. Summary of Significant Accounting Policies

Organization, operations, and basis of consolidation

The consolidated financial statements include the accounts of L.B. Foster Company and its wholly-owned subsidiaries, joint ventures, and partnerships in which a controlling interest is held. Inter-company transactions and accounts have been eliminated. The Company utilizes the equity method of accounting for companies where its ownership is less than or equal to 50% and significant influence exists.

L.B. Foster Company (“Company”) is a leading manufacturer and distributor of products and service provider for transportation and energy infrastructure with locations in North America and Europe. The Company is organized and operates in three business segments: Rail Products and Services (“Rail”), Construction Products (“Construction”), and Tubular and Energy Services (“Tubular and Energy”). The Rail segment is comprised of several manufacturing and distribution businesses that provide a variety of products and services for freight and passenger railroads and industrial companies throughout the world. The Construction segment is composed of piling, fabricated bridge, and precast concrete product offerings across North America. The Tubular and Energy segment provides products and services predominantly to the U.S. mid and upstream oil and gas markets.

Use of estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates, judgements, and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates and changes in these estimates are recorded when known.

Significant accounting policies

Cash and cash equivalents

The Company considers cash and other instruments with maturities of three months or less when purchased to be cash and cash equivalents. The Company invests available funds in a manner to maximize returns, preserve investment principal, and maintain liquidity, while seeking the highest yield available.

Cash and cash equivalents held in non-domestic accounts were $13,660 and $8,058 as of December 31, 2019 and 2018, respectively. Included in non-domestic cash equivalents are investments in bank term deposits of approximately $17 and $16 as of December 31, 2019 and 2018, respectively. The carrying amounts approximated fair value due to the short maturity of the instruments.

Inventory

Inventory is valued at the lower of average cost or net realizable value. Slow-moving inventory is reviewed and adjusted regularly, based upon product knowledge, physical inventory observation, inventory turnover, and the age of the inventory. Inventory contains product costs, including inbound freight, direct labor, overhead costs relating to the manufacturing and distribution of products, and absorption costs representing the excess manufacturing or production costs over the amounts charged to the cost of sales or services.

Property, plant, and equipment

Depreciation and amortization are provided on a straight-line basis over the estimated useful lives of 7 to 40 years for buildings and 2 to 13 years for machinery and equipment. Leasehold improvements are amortized over 6 to 10 years, which represent the lives of the respective leases or the lives of the improvements, whichever is shorter. Depreciation expense is recorded within “Cost of goods sold,” “Cost of services sold,” and “Selling and administrative expenses” on the Consolidated Statements of Operations based upon the particular asset’s use. The Company reviews a long-lived asset for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The Company recognizes an impairment loss if the carrying amount of a long-lived asset is not recoverable and exceeds its fair value. There were no property, plant, and equipment impairments recorded for the years ended December 31, 2019 and 2018.

Maintenance, repairs, and minor renewals are charged to operations as incurred. Major renewals and betterments that substantially extend the useful life of the property are capitalized at cost. Upon sale or other disposition of assets, the costs and related accumulated depreciation and amortization are removed from the accounts and the resulting gain or loss, if any, is reflected in “Other income or expense.”

Allowance for doubtful accounts

The allowance for doubtful accounts is recorded to reflect the estimated realization of the Company’s accounts receivable and includes assessments of the probability of collection and the credit-worthiness of certain customers. Reserves for uncollectible accounts are recorded as part of “Selling and administrative expenses” on the Consolidated Statements of Operations. The Company reviews its accounts receivable aging and calculates an allowance through application of historic reserve factors to overdue receivables. This calculation is supplemented by specific account reviews performed by the Company’s credit department. As

32

necessary, the application of the Company’s allowance rates to specific customers is reviewed and adjusted to more accurately reflect the credit risk inherent within that customer relationship.

Goodwill and other intangible assets

Goodwill is the cost of an acquisition less the fair value of the identifiable net assets of the acquired business. Goodwill is tested annually for impairment or more often if there are indicators of impairment within a reporting unit. A reporting unit is an operating segment or a component of an operating segment for which discrete financial information is available and reviewed by management on a regular basis. The goodwill impairment test involves comparing the fair value of a reporting unit to its carrying value, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss equal to the excess amount up to the goodwill balance is recorded as a component of operations. The Company performs its annual impairment tests in the fourth quarter.

The Company’s fourth quarter 2019 annual test included the assessment of qualitative factors to determine whether it was more likely than not that the fair value of each reporting unit is less than its carrying value. The qualitative assessment encompassed a review of events and circumstances specific to each reporting unit with goodwill, as well as specific to the entity as a whole. The Company’s qualitative assessment considered, among other things, factors such as macroeconomic conditions, industry and market considerations, including changes in the Company’s stock price and market multiples, projected financial performance, cost factors, changes in carrying values, and other relevant factors. Considering the totality of the qualitative factors assessed, based on the weight of evidence, no circumstances existed that would indicate it was more likely than not that goodwill was impaired. There was no goodwill impairment recognized during 2019 or 2018. The Company continues to monitor the recoverability of the long-lived assets associated with certain reporting units of the Company and the long-term financial projections of the businesses. Sustained declines in the markets we serve may result in future long-lived asset impairment.

The Company has no indefinite-lived intangible assets. The Company reviews a long-lived intangible asset for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. All intangible assets are amortized over their estimated useful lives. There were no definite-lived intangible asset impairments during the years ended December 31, 2019 and 2018.

Environmental remediation and compliance

Environmental remediation costs are accrued when the liability is probable and costs are estimable. Environmental compliance costs, which principally include the disposal of waste generated by routine operations, are expensed as incurred. Capitalized environmental costs, when appropriate, are depreciated over their useful life. Reserves are not reduced by potential claims for recovery and are not discounted. Claims for recovery are recognized as agreements are reached with third parties or as amounts are received. Reserves are periodically reviewed throughout the year and adjusted to reflect current remediation progress, prospective estimates of required activity, and other factors that may be relevant, including changes in technology or regulations. See Note 18 for additional information regarding the Company’s outstanding environmental and litigation reserves.

Revenue recognition

The Company’s revenues are comprised of product and service sales, including products and services provided under long-term agreements with its customers. All revenue is recognized when the Company satisfies its performance obligations under the contract, either implicit or explicit, by transferring the promised product or rendering a service to its customer either when or as its customer obtains control of the product or the service is rendered. Deferred revenue consists of customer billings or payments received for which the revenue recognition criteria have not yet been met as well as contract liabilities (billings in excess of costs) on over time contracts. Advance payments from customers typically relate to contracts for which the Company has significantly fulfilled its obligations, but due to the Company’s continuing involvement with the project, revenue is precluded from being recognized until the performance obligation is met for the customer. See Note 3 for additional information.

Product warranty

The Company maintains a current warranty liability for the repair or replacement of defective products. For certain manufactured products, an accrual is made on a monthly basis as a percentage of cost of sales based upon historical experience. For long-lived construction products, a warranty is established when the claim is known and quantifiable. The product warranty accrual is periodically adjusted based on the identification or resolution of known individual product warranty claims or due to changes in the Company’s historical warranty experience. As of December 31, 2019 and 2018, the product warranty reserve was $1,222 and $2,057, respectively. See Note 18 for additional information regarding the product warranty.

Income taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. Deferred taxes are measured using enacted tax laws and rates expected to be in effect when such differences are recovered or settled. The effect of a change in tax rates on deferred taxes is recognized in income in the period that includes the enactment date of the change. The Company has also elected to record global intangible low-taxed income (“GILTI”) as period costs if and when incurred.

33

The Company makes judgments regarding the recognition of deferred tax assets and the future realization of these assets. As prescribed by the Financial Accounting Standards Board’s (“FASB”) Accounting Standard Codification (“ASC”) 740, “Income Taxes” and applicable guidance, valuation allowances must be provided for those deferred tax assets for which it is more likely than not (a likelihood of more than 50%) that some portion or all of the deferred tax assets will not be realized. The guidance requires the Company to evaluate positive and negative evidence regarding the recoverability of deferred tax assets. The determination of whether the positive evidence outweighs the negative evidence and quantification of the valuation allowance requires the Company to make estimates and judgments of future financial results. The Company has concluded that for purposes of quantifying valuation allowances, it would be appropriate to consider the reversal of taxable temporary differences related to indefinite-lived intangible assets when assessing the realizability of deferred tax assets that upon reversal, would give rise to operating losses that do not expire.

The Company evaluates all tax positions taken on its federal, state, and foreign tax filings to determine if the position is more likely than not to be sustained upon examination. For positions that meet the more likely than not to be sustained criteria, the largest amount of benefit to be realized upon ultimate settlement is determined on a cumulative probability basis. A previously recognized tax position is derecognized when it is subsequently determined that a tax position no longer meets the more likely than not threshold to be sustained. The evaluation of the sustainability of a tax position and the expected tax benefit is based on judgment, historical experience, and various other assumptions. Actual results could differ from those estimates upon subsequent resolution of identified matters. The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes.

Foreign currency translation

The assets and liabilities of our foreign subsidiaries are measured using the local currency as the functional currency and are translated into U.S. dollars at exchange rates as of the balance sheet date. Income statement amounts are translated at the weighted-average rates of exchange during the year. The translation adjustment is accumulated as a separate component of “Accumulated other comprehensive loss” within our Consolidated Balance Sheets. Foreign currency transaction gains and losses are included in “Other income or expense.” For the years ended December 31, 2019 and 2018, foreign currency transaction losses of approximately $202 and gains of $483, respectively, were included in “Other expense (income) - net” in the Consolidated Statements of Operations.

Research and development

The Company expenses research and development costs as costs are incurred. For the years ended December 31, 2019 and 2018, research and development expenses were $2,614 and $2,646, respectively, and were principally related to the Company’s friction management and railroad monitoring system products within the Rail Products and Services segment.

Reclassifications

Certain accounts in the prior year consolidated financial statements have been reclassified for comparative purposes principally to conform to the presentation in the current year period.

Recently issued accounting guidance

In August 2018, the FASB issued Accounting Standards Update (“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 is a service contract. The amendments in ASU 20118-15 are effective for fiscal years beginning after December 15, 2019 and for interim periods therein with early adoption permitted. The Company evaluated the potential impact of ASU 2018-15 on its consolidated financial position, results of operations, and cash flows and anticipates the adoption will have an immaterial effect on the Company’s Consolidated Financial Statements.

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. 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 will need to measure expected credit losses on assets that have a low risk of loss. The new standard will become effective for the Company January 1, 2020 and will be applied using the modified retrospective basis. The Company anticipates the adoption of this standard will not have a material impact on the Company’s Consolidated Financial Statements.

Recently adopted accounting guidance

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The new accounting requirements include the accounting for, presentation of, and classification of leases. The guidance resulted in most leases being capitalized as a right-of-use asset with a related balance sheet liability. The requirements of the new standard are effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. The Company adopted the provisions of ASU 2016-02 on January 1, 2019, using the modified retrospective approach as of the beginning of the period of adoption. Additionally, the Company has elected to apply the practical expedients for leases that commenced prior to the effective date, not to apply the recognition requirements in the standard to short-term leases, and not to separate non-lease components from lease components. The Company has presented the disclosures required by ASU 2016-02 in Note 8.

34

In February 2018, the FASB issued ASU 2018-02, “Income Statement – Reporting Comprehensive Income; Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”), which allows companies to reclassify stranded tax effects caused by the U.S. Tax Cuts and Jobs Act (the “Tax Act”) from accumulated other comprehensive income to retained earnings. The amendments eliminate the stranded tax effects resulting from the Tax Act and improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The Company adopted ASU 2018-02 during the first quarter of 2019 and has chosen to record the reclassification as of the beginning of the period of adoption. As a result of adopting this standard, we reclassified stranded tax effects of $633 from “Accumulated other comprehensive loss” to “Retained earnings.”

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 is organized and operates in three different operating segments: the Rail Products and Services segment, the Construction Products segment, and the Tubular and Energy Services segment. The 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 makes 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 markets its products directly in all major industrial areas of the United States, Canada, and Europe, primarily through an internal sales force.

The Company’s Rail Products and Services segment provides a full line of new and used rail, trackwork, and accessories to railroads, mines, and other customers in the rail industry. The Rail Products and Services segment also designs and produces insulated rail joints, power rail, track fasteners, concrete railroad ties, coverboards, and special accessories for mass transit and other rail systems. In addition, the Rail Products and Services segment engineers, manufactures, and assembles friction management products and railway wayside data collection, application systems, railroad condition monitoring systems and equipment, wheel impact load detection, fire protection systems, and management systems.

The Company’s Construction Products segment sells and rents steel sheet piling, H-bearing pile, and other piling products for foundation and earth retention requirements. The Construction Products segment also sells bridge decking, bridge railing, structural steel fabrications, expansion joints, bridge forms, and other products for highway construction and repair. Lastly, the Construction Products segment produces precast concrete buildings and a variety of specialty precast concrete products.

The Company’s Tubular and Energy Services segment provides pipe coatings for natural gas pipelines and utilities, upstream test and inspection services, precision measurement systems for the oil and gas market, and produces threaded pipe products for the oil and gas markets as well as industrial water well and irrigation markets.

The following table illustrates net sales, profit, assets, depreciation/amortization, and expenditures for long-lived assets of the Company by segment. Segment profit from operations includes allocated corporate operating expenses. Operating expenses related to corporate headquarter functions that directly support the segment activity were 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.

Management believes the allocation of corporate operating expenses provides an accurate presentation of how the segments utilize corporate support activities. This provides the CODM a meaningful segment profitability reporting to support operating decisions and the allocation of resources.

The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies found in Note 1.

The operating results and assets of the Company’s operating segments were as follows as of and for the year ended December 31, 2019:

Note 3. Revenue

The Company’s revenues are comprised of product and service sales, including products and services provided under long-term agreements with its customers. All revenue is recognized when the Company satisfies its performance obligations under the contract, either implicit or explicit, by transferring the promised product or rendering a service to its customer either when or as its customer obtains control of the product or as the service is rendered. A performance obligation is a promise in a contract to transfer a distinct product or render a specific service to a customer. A contract’s transaction price is allocated to each distinct performance obligation. The majority of the Company’s contracts have a single performance obligation, as the promise to transfer products or render services is not separately identifiable from other promises in the contract and, therefore, not distinct. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or providing services. Revenue is recorded net of returns, allowances, customer discounts, and incentives. Sales, value added, and other taxes collected from customers and remitted to governmental authorities are accounted for on a net (excluded from revenues) basis. Shipping and handling costs are included in cost of goods sold.

The Company’s performance obligations under long-term agreements with its customers are generally satisfied as over time. Over time revenue is primarily comprised of transit infrastructure projects within Rail Products and Rail Technologies, long-term bridge projects within Piling and Fabricated Bridge Products, precast concrete buildings within Precast Concrete Products, and custom precision metering systems within Protective Coatings and Measurement Systems. Revenue from products or services provided to customers over time accounted for 28.5% and 26.0% of revenue for the years ended December 31, 2019 and 2018, 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 $136,014 and $121,919 for the years ended December 31, 2019 and 2018, 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 $50,761 and $41,334 for the years ended December 31, 2019 and 2018, respectively. As of December 31, 2019 and 2018, the Company had contract assets of $37,032 and $26,692, respectively, that were recorded in “Inventories - net” within the Consolidated Balance Sheets. As of December 31, 2019 and 2018, the Company had contract liabilities of $4,472 and $1,505, respectively, that were recorded in “Deferred revenue” within the Consolidated Balance Sheets.

Accounting for these long-term agreements involves the use of various techniques to estimate total revenues and costs. The Company estimates profit on these long-term agreements as the difference between total estimated revenues and expected costs to complete a contract and recognizes that profit over the life of the contract. Contract estimates are based on various assumptions to project the outcome of future events that may span several years. These assumptions include, among other things, labor productivity, cost and availability of materials, and timing of funding by customers. The nature of these long-term agreements may give rise to several types of variable consideration, such as claims, awards, and incentive fees. Historically, these amounts of variable consideration have not been considered significant. Contract estimates may include additional revenue for submitted contract modifications if there exists an enforceable right to the modification, the amount can be reasonably estimated, and its realization is probable. These estimates are based on historical collection experience, anticipated performance, and the Company’s best judgment at

37

that time. These amounts are generally included in the contract’s transaction price and are allocated over the remaining performance obligations. Changes in judgments related to the estimates above could impact the timing and amount of revenue recognized and, accordingly, the timing and amount of associated income. In the event that a contract loss becomes known, the entire amount of the estimated loss is recognized in the Consolidated Statements of Operations.

The majority of the Company’s revenue is from products transferred and services rendered to customers at a point in time, which is inherent in all major product and service categories. Point in time revenue accounted for 71.5% and 74.0% of revenue for the years ended December 31, 2019 and 2018, respectively. The Company recognizes revenue at the point in time in which the customer obtains control of the product or service, which is generally when 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 designated physical location.

The following table summarizes the Company’s net sales by major product and service category:

	December 31,
	2019		2018
Rail Products	$	194,464	$	188,590
Rail Technologies	127,344		130,934
Rail Products and Services	321,808		319,524
Piling and Fabricated Bridge Products	114,076		102,246
Precast Concrete Products	68,410		56,407
Construction Products	182,486		158,653
Test, Inspection, and Threading Services	51,003		59,766
Protective Coatings and Measurement Systems	99,760		89,026
Tubular and Energy Services	150,763		148,792
Total net sales	$	655,057	$	626,969

For the years ended December 31, 2019 and 2018, net sales by the timing of the transfer of goods and services are as follows:

Year ended December 31, 2019	Rail Products and Services		Construction Products		Tubular and Energy Services		Total
Point in time	$	240,047	$	115,590	$	112,645	$	468,282
Over time	81,761		66,896		38,118		186,775
Total net sales	$	321,808	$	182,486	$	150,763	$	655,057
Year ended December 31, 2018	Rail Products and Services		Construction Products		Tubular and Energy Services		Total
Point in time	$	232,814	$	106,168	$	124,734	$	463,716
Over time	86,710		52,485		24,058		163,253
Total net sales	$	319,524	$	158,653	$	148,792	$	626,969

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 Consolidated Balance Sheets.

Significant changes in contract assets during the year ended December 31, 2019 and 2018 included transfers to receivables from contract assets recognized at the beginning of the period of $24,487 and $18,941, respectively. Significant changes in contract liabilities during the year ended December 31, 2019 and 2018 included increases of $4,358 and $1,447, respectively, 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 year ended December 31, 2019 and 2018 of $1,462 and $1,141, respectively, that were included in the contract liabilities at the beginning of the respective period.

As of December 31, 2019, the Company had approximately $230,067 of remaining performance obligations, which is also referred to as backlog. Approximately 8.3% of the backlog as of December 31, 2019 was related to projects that are anticipated to extend beyond December 31, 2020.

Note 7. Property, Plant, and Equipment

Property, plant, and equipment as of December 31, 2019 and 2018 consisted of the following:

	December 31,
	2019		2018
Land	$	11,076	$	12,440

Depreciation expense, including amortization of assets under capital leases, for the years ended December 31, 2019 and 2018 amounted to $11,054 and $11,495, respectively.

During the year ended December 31, 2019, the Company sold land and building for cash proceeds of $900, resulting in a gain of $198. During the year ended December 31, 2018, the Company sold 54.5 acres of land in exchange for cash proceeds of $2,047, resulting in a loss of $269.

Note 8. Leases

On January 1, 2019, the Company adopted ASU 2016-02 and all related amendments using the modified retrospective approach, which resulted in an increase in assets of $13,585 and an increase in current and long-term liabilities of $3,322 and $10,263, respectively. This adoption did not affect the Company’s results of operations or cash flows.

The Company determines if an arrangement is a lease at its inception. Operating leases are included in “Operating lease right-of-use assets,” “Other current liabilities,” and “Long-term operating lease liabilities” within the Company’s Consolidated Balance

40

Sheets. Finance leases are included in “Property, plant, and equipment - net,” “Current maturities of long-term debt,” and “Long-term debt” in the Company’s Consolidated Balance Sheets.

Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of the lease payments. The Company uses the implicit rate when readily determinable. The operating lease right-of-use asset also includes indirect costs incurred and lease payments made prior to the commencement date, less any lease incentives received. The Company’s lease terms may include options to extend or terminate the lease and will be recognized when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

The Company has lease agreements with lease and non-lease components that it accounts for as a single lease component. Also, for certain equipment leases, the Company applies a portfolio approach to effectively account for the operating lease right-of-use assets and liabilities.

Finance lease and lessor accounting recognition has remained substantially unchanged under ASU 2016-02. The adoption of ASU 2016-02 had no impact on the Company’s balance sheet, results of operations, or cash flows for finance leases.

The Company has operating and finance leases for manufacturing facilities, corporate offices, sales offices, vehicles, and certain equipment. As of December 31, 2019, its leases had remaining lease terms of 1 to 12 years, some of which include options to extend the leases for up to 12 years, and some of which include options to terminate the leases within 1 year. As of December 31, 2019, the Company’s operating leases had a weighted average remaining lease term of 7 years and a weighted average discount rate of 5.1%. As of December 31, 2019, the Company’s finance leases had a weighted average remaining lease term of 1 year and a weighted average discount rate of 4.3%.

The balance sheet components of the Company’s leases were as follows as of December 31, 2019:

	December 31, 2019

Note 9. Deferred Revenue

Deferred revenue of $8,446 and $6,619 as of December 31, 2019 and 2018, respectively, consists of customer billings or payments received for which the revenue recognition criteria have not yet been met as well as contract liabilities (billings in excess of costs) on over time revenue projects. As of December 31, 2019 and 2018, contract liabilities, recorded within “Deferred revenue,” was $4,472 and $1,505, respectively. Advanced payments from customers typically relate to contracts with respect to which the Company has significantly fulfilled its obligations, but due to the Company’s continuing involvement with the project, revenue is not recognized until title, ownership, and risk of loss have passed to the customer.

Note 10. Long-Term Debt and Related Matters

Borrowings

On April 30, 2019, the Company, its domestic subsidiaries, and certain of its Canadian and European subsidiaries (collectively, the “Borrowers”), entered into the Third Amended and Restated Credit Agreement (“Amended 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. This Amended Credit Agreement modifies the prior revolving credit facility, which had a maximum credit line of $195,000 and extends the maturity date from March 13, 2020 to April 30, 2024. The Amended Credit Agreement provides for a five-year, revolving credit facility that permits aggregate borrowings of the Borrowers up to $140,000 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. The Amended 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 and provides for additional term loan borrowings of up to $25,000 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 Amended 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 their domestic subsidiaries, have been pledged to the lenders as collateral for the lending obligations.

Borrowings under the Amended Credit Agreement bear interest at rates based upon either the base rate or Euro-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 Amended 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 Amended Credit Agreement). The base rate and Euro-rate spreads range from 25 to 125 basis points and 125 to 225 basis points, respectively.

The Amended Credit Agreement includes three 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, as defined in the Amended Credit Agreement, and (ii) 3.50 to 1.00 for all testing periods 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, as defined in the Amended Credit Agreement, which must be a minimum of 1.25 to 1.00; and (c) Minimum Working Capital to Revolving Facility Usage Ratio, defined as the sum of the inventory and accounts receivable of the Borrowers and certain other Guarantors divided by the Revolving Facility Usage, as defined in the Amended Credit Agreement, which must be a minimum of 1.40 to 1.00.

As of December 31, 2019, the Company was in compliance with the covenants in the Amended Credit Agreement.

As of December 31, 2019 and 2018, the Company had outstanding letters of credit of approximately $492 and $425, respectively, and had net available borrowing capacity of $105,640 and $120,567, respectively.

United Kingdom

On April 29,2019, a subsidiary of the Company terminated a credit facility with NatWest Bank used for its United Kingdom operations. The facility had included an overdraft availability of £1,500 pounds sterling (approximately $1,924 as of December 31, 2018). There were no outstanding borrowings under this credit facility as of December 31, 2018, however, there were $318 in outstanding guarantees (as defined in the underlying agreement) as of December 31, 2018. The subsidiary had available borrowing capacity of $1,606 as of December 31, 2018.

Note 11. Stockholders’ Equity

The Company had authorized shares of 20,000,000 in common stock with 11,115,779 shares issued as of December 31, 2019 and 2018. The common stock has a par value of $0.01 per share and the Company suspended its dividend payments during each year ended December 31, 2019 and 2018, respectively.

Each quarter, management reviews operations and liquidity needs in each jurisdiction to assess the Company’s intent to reinvest foreign earnings outside of the United States. As of December 31, 2019, management determined that cash balances of its Canadian and United Kingdom subsidiaries exceeded projected capital needs by $7,800. Management does not intend for such amounts to be permanently reinvested outside of the United States and has therefore accrued foreign withholding taxes of $390 as of December 31, 2019. It is management’s intent and practice to indefinitely reinvest other undistributed earnings outside of the United States. Determination of the amount of any unrecognized deferred income tax liability associated with these undistributed earnings is not practicable because of the complexities of the hypothetical calculation.

A valuation allowance is required to be established or maintained when, based on currently available information and other factors, it is more likely than not that all or a portion of a deferred tax asset will not be realized. The Company has considered all available evidence, both positive and negative, in assessing the need for a valuation allowance in each jurisdiction.

During 2019, the Company reversed $29,648 of its valuation allowance previously recorded against U.S. deferred tax assets. The positive evidence considered in evaluating U.S. deferred tax assets included cumulative financial income over the three-year period ended December 31, 2019, as well as the composition and reversal patterns of existing taxable and deductible temporary differences between financial reporting and tax. Based on our evaluation, the Company believed it was appropriate to rely on forecasted future taxable income to support its U.S. deferred tax assets. The amount of deferred tax assets considered realizable, however, could be adjusted if negative evidence outweighs additional subjective evidence such as our projections for growth.

As of December 31, 2019 and 2018, the tax benefit of net operating loss carryforwards available for state income tax purposes was $901 and $1,253, respectively. The state net operating loss carryforwards will expire in various years through 2039. We believe it is more likely than not that a portion of the tax benefit from state operating loss carryforwards will not be realized. In recognition of this risk, we have provided a valuation allowance of $388 against deferred tax assets related to state operating loss carryforwards as of December 31, 2019.

As of December 31, 2019, the Company has foreign tax credit carryforwards in the amount of $34 that will expire in 2028 through 2029. We believe it is more likely than not that the tax benefit from foreign tax credit carryforwards will not be realized. In recognition of this risk, we have provided a valuation allowance of $34 against deferred tax assets related to foreign tax credit carryforwards at December 31, 2019.

As of December 31, 2019, the Company has net operating loss carryforwards in certain foreign jurisdictions of $2,019, which may be carried forward indefinitely. The foreign jurisdictions have incurred cumulative financial losses over the three-year period ended December 31, 2019 and have projected future taxable losses. We believe it is more likely than not that the tax benefit from these

46

loss carryforwards will not be realized. In recognition of this risk, we have provided a valuation allowance of $650, collectively, against deferred tax assets in foreign jurisdictions as of December 31, 2019.

The determination to record or not record a valuation allowance involves management judgment, based on the consideration of positive and negative evidence available at the time of the assessment. Management will continue to assess the realization of its deferred tax assets based upon future evidence, and may record adjustments to valuation allowances against deferred tax assets in future periods, as appropriate, that could materially impact net income.

The following table provides a reconciliation of unrecognized tax benefits as of December 31, 2019 and 2018:

	December 31,
	2019		2018
Unrecognized tax benefits at beginning of period:	$	481	$	599
Decreases based on tax positions for prior periods	(67)		(118)
Balance at end of period	$	414	$	481

The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $414 as of December 31, 2019. The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes. As of December 31, 2019 and 2018, the Company had accrued interest and penalties related to unrecognized tax benefits of $327 and $398, respectively. As of December 31, 2019, the Company did not expect any material increases or decreases to its unrecognized tax benefits within the next 12 months. Ultimate realization of these tax benefits is dependent upon the occurrence of certain events, including the completion of audits by tax authorities and expiration of statutes of limitations.

The Company files income tax returns in the United States and in various state, local, and foreign jurisdictions. The Company is subject to federal income tax examinations for the 2016 period and thereafter. With respect to the state, local, and foreign filings, certain entities of the Company are subject to income tax examinations for the 2015 period and thereafter.

Note 15. 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 period. Stock forfeitures and cancellations are recognized as they occur. The Company recorded stock-based compensation expense of $3,155 and $3,836 for the years ended December 31, 2019 and 2018, respectively, related to fully-vested stock awards, restricted stock awards, and performance unit awards. As of December 31, 2019, unrecognized compensation expense for awards the Company expects to vest approximated $3,576. The Company will recognize this unrecognized compensation expense over approximately 3.2 years.

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

As of December 31, 2019, the Company had stock awards issued pursuant to the 2006 Omnibus Incentive Plan, as amended and restated in May 2018 (“Omnibus Plan”). The Omnibus Plan allows for the issuance of 2,058,000 shares of common stock through the granting of stock options or stock awards (including performance units convertible into stock) to key employees and directors at no less than 100% of fair market value on the date of the grant. The Omnibus Plan provides for the granting of “nonqualified options” with a duration of not more than ten years from the date of grant. The Omnibus Plan also provides that, unless otherwise set forth in the option agreement, stock options are exercisable in installments of up to 25% annually beginning one year from the date of grant. No stock options have been granted under the Omnibus Plan and, as such, there was no stock-based compensation expense related to stock options recorded in 2019 or 2018.

Non-Employee Director Fully-Vested and Restricted Stock Awards

Prior to May 2018, non-employee directors were awarded fully-vested shares of the Company’s common stock on each date the non-employee directors were elected at the annual shareholders’ meeting to serve as directors. Since May 2018, such annual equity awards have been subject to a one-year vesting requirement. During the quarter ended June 30, 2017, the Nomination and Governance Committee and Board of Directors jointly approved the Deferred Compensation Plan for Non-Employee Directors under the Omnibus Plan, which permits non-employee directors of the Company to defer receipt of earned cash and/or stock compensation for service on the Board.

The non-employee directors were granted a total of 21,532 and 24,427 fully-vested and restricted shares for the years ended December 31, 2019 and 2018, respectively. Compensation expense recorded by the Company related to such awards to non-employee directors was approximately $526 and $880 for the years ended December 31, 2019 and 2018, respectively. During 2019, 12,304 deferred share units were allotted to the accounts of the non-employee directors pursuant to the Deferred Compensation Plan for Non-Employee Directors.

The weighted average fair value of all the fully-vested and restricted stock grants awarded was $24.38 and $23.64 per share for the years ended December 31, 2019 and 2018, respectively.

Restricted Stock Awards and Performance Unit Awards

Under the Omnibus Plan, the Company grants certain employees restricted stock and performance unit awards. The forfeitable restricted stock awards granted prior to March 2015 generally time-vest after a four-year period, and those granted subsequent to March 2015 generally time-vest ratably over a three-year period, unless indicated otherwise by the underlying restricted stock award agreement. Performance unit awards are offered annually under separate three-year long-term incentive programs. Performance units are subject to forfeiture and will be converted into common stock 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 stock awards expected to vest changes in a subsequent accounting period, cumulative compensation expense could increase or decrease. The change is recognized in the current period for the performance unit awards and would change future expense over the remaining service period.

The following table summarizes the restricted stock award, deferred stock units, and performance unit award activity for the years ended December 31, 2019 and 2018:

	Restricted Stock	Deferred Stock Units	Performance Stock Units	Weighted Average Aggregate Grant Date Fair Value
Outstanding as of January 1, 2018	186,806	26,860	181,341	$	16.53

Outstanding as of December 31, 2019	150,799	54,078	331,148	$	18.50

Performance 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 plan. Performance Stock Units are adjusted to the Company’s expected performance target attainment, while the aggregate fair value in the above table is based upon achieving 100% of the performance targets as defined in the underlying plan.

Excluding the fully-vested and restricted stock awards granted to non-employee directors, the Company recorded stock-based compensation expense of $2,630 and $2,956, respectively, for the periods ended December 31, 2019 and 2018 related to restricted stock and performance unit awards.

Note 16. 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 of the applicable plan. The Company’s policy is to contribute at least the required minimum in accordance with the funding standards of ERISA.

The Company maintains two defined contribution plans for its employees in Canada, as well as a post-retirement benefit plan. In the United Kingdom, the Company maintains two defined contribution plans and a defined benefit plan, which is frozen. These plans are discussed in further detail below.

The weighted average assumptions in the following table represent the rates used to develop the actuarial present value of the projected benefit obligation for the year listed and also the net periodic benefit cost for the following year.

	Year Ended December 31,
	2019		2018
Discount rate	4.0	%	3.4	%
Expected rate of return on plan assets	5.9	%	5.9	%

The expected long-term rate of return is based on numerous factors, including the target asset allocation for plan assets, historical rate of return, long-term inflation assumptions, and current and projected market conditions.

49

Amounts applicable to the Company’s pension plan with accumulated benefit obligations in excess of plan assets were as follows as of December 31, 2019 and 2018:

	December 31,
	2019		2018
Projected benefit obligation	$	7,809	$	16,717
Accumulated benefit obligation	7,809		16,717
Fair value of plan assets	4,360		12,468

Plan assets consist primarily of various fixed income and equity investments. The Company’s primary investment objective is to provide long-term growth of capital while accepting a moderate level of risk. The investments are limited to cash and cash equivalents, bonds, preferred stocks, and common stocks. The investment target ranges and actual allocation of pension plan assets by major category as of December 31, 2019 and 2018 were as follows:

		December 31,
	Target	2019		2018
Asset Category
Cash and cash equivalents	0 - 20%	19	%	3	%
Total fixed income funds	25 - 50%	30		28
Total mutual funds and equities	35 - 70%	51		69
Total		100	%	100	%

In accordance with the fair value disclosure requirements of ASC 820, “Fair Value Measurements and Disclosures,” the following assets were measured at fair value on a recurring basis as of December 31, 2019 and 2018. Additional information regarding ASC 820 and the fair value hierarchy can be found in Note 18.

	December 31,
	2019		2018

Exchange-traded funds	1,513		6,711
Total mutual funds and equities	2,207		8,592
Total	$	4,360	$	12,468

Cash equivalents: The Company uses quoted market prices to determine the fair value of these investments in interest-bearing cash accounts and they are classified as Level 1 of the fair value hierarchy. The carrying amounts approximate fair value because of the short maturity of the instruments.

Fixed income funds: Investments within the fixed income funds category consist of fixed income corporate debt. The Company uses quoted market prices to determine the fair values of these fixed income funds. These instruments consist of exchange-traded government and corporate bonds and are classified as Level 1 of the fair value hierarchy.

Equity funds and equities: The valuation of investments in registered investment companies is based on the underlying investments in securities. Securities traded on security exchanges are valued at the latest quoted sales price. Securities traded in the over-the-counter market and listed securities for which no sale was reported on that date are valued at the average of the last reported bid and ask quotations. These investments are classified as Level 1 of the fair value hierarchy.

The Company currently anticipates contributions of $660 to its United States defined benefit plan in 2020.

The Company has estimated the long-term rate of return on plan assets based primarily on historical returns on plan assets, adjusted for changes in target portfolio allocations, and recent changes in long-term interest rates based on publicly available information.

Plan assets are invested by the trustees in accordance with a written statement of investment principles. This statement permits investment in equities, corporate bonds, United Kingdom government securities, commercial property, and cash, based on certain target allocation percentages. Asset allocation is primarily based on a strategy to provide steady growth without undue fluctuations. The target asset allocation percentages for 2019 were as follows:

	Portec Rail
	Plan
Equity securities	Up to 100%
Commercial property	Not to exceed 50%
U.K. Government securities	Not to exceed 50%
Cash	Up to 100%

Plan assets held within the United Kingdom defined benefit plan consist of cash and equity securities that have been classified as Level 1 of the fair value hierarchy. All other plan assets have been classified as Level 2 of the fair value hierarchy.

The plan assets by category for the years ended December 31, 2019 and 2018 were as follows:

	December 31,
	2019		2018
Asset Category
Cash and cash equivalents	$	516	$	685
Equity securities	2,090		2,001
Bonds	3,735		2,866
Other	949		795
Total	$	7,290	$	6,347

United Kingdom regulations require trustees to adopt a prudent approach to funding required contributions to defined benefit pension plans. The Company anticipates making contributions of $318 to the United Kingdom defined benefit plan during 2020.

The following estimated future benefits payments are expected to be paid under the United Kingdom defined benefit plan:

Year Ending December 31,
2020	$	280
2021	299
2022	312
2023	370
2024	396
Years 2025-2029	1,744

Other Post-Retirement Benefit Plan

The Company’s operation near Montreal, Quebec, Canada, maintains a post-retirement benefit plan, which provides retiree life insurance, health care benefits, and, for a closed group of employees, dental care. Retiring employees with a minimum of 10 years of

52

service are eligible for the plan benefits. The plan is not funded. Cost of benefits earned by employees is charged to expense as services are rendered. The expense related to this plan was not material for 2019 or 2018. The accrued benefit obligation was $840 and $724 as of December 31, 2019 and 2018, respectively. This obligation is recognized within “Other long-term liabilities” on the Consolidated Balance Sheets. During 2018, the plan recognized a curtailment gain of $113. Benefit payments anticipated for 2020 are not material.

The weighted average assumptions in the following table represent the rates used to develop the actuarial present value of the projected benefit obligation for the year listed and also the net periodic benefit cost for the following year.

	Year Ended December 31,
	2019		2018
Discount rate	3.1	%	3.8	%
Weighted average health care trend rate	4.9	%	4.9	%

Note 17. 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.

The Company has an established process for determining fair value for its financial assets and liabilities, principally cash and cash equivalents and interest rate swaps. Fair value is based on quoted market prices, where available. If quoted market prices are not available, fair value is based on assumptions that use as inputs market-based parameters. The following section describes the valuation methodologies used by the Company to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which each instrument is generally classified. Where appropriate, the description includes details of the key inputs to the valuations and any significant assumptions.

Cash equivalents. Included within “Cash and cash equivalents” 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 swaps became effective in February 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. 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 have been classified as Level 2 within the fair value hierarchy. When the interest rate swap fair market value is in an asset position, they are recorded in “Other current assets” and when in a liability position, they are recorded in “Other accrued liabilities” within our Consolidated Balance Sheets.

53

The following assets and liabilities of the Company were measured at fair value on a recurring basis subject to the disclosure requirements of ASC 820, “Fair Value Measurement,” as of December 31, 2019 and 2018:

	Fair Value Measurements as of December 31, 2019								Fair Value Measurements as of December 31, 2018
	December 31, 2019		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		December 31, 2018		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Term deposits	$	17	$	17	$	—	$	—	$	16	$	16	$	—	$	—
Interest rate swaps	—		—		—		—		675		—		675		—
Total assets	$	17	$	17	$	—	$	—	$	691	$	16	$	675	$	—
Interest rate swaps	$	480	$	—	$	480	$	—	$	—	$	—	$	—	$	—
Total liabilities	$	480	$	—	$	480	$	—	$	—	$	—	$	—	$	—

The interest rate swaps 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 domestic debt. Therefore, the gains and losses related to the interest rate swaps are reclassified from “Accumulated other comprehensive loss” and included in “Interest expense - net” in our Consolidated Statements of Operations. For the year ended December 31, 2019 and 2018, interest income from interest rate swaps was $114 and $34, respectively.

The gross carrying value of the Company’s revolving credit facility approximates fair value for the periods presented. Additional information regarding the revolving credit facility can be found in Note 10.

Information regarding the fair value disclosures associated with the assets of the Company’s defined benefit plans can be found in Note 16.

Note 18. Commitments and Contingent Liabilities

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 that is adjusted on a monthly basis as a percentage of cost of sales. This product warranty accrual is periodically adjusted 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, 2018	$	2,057
Additions to warranty liability	767
Warranty liability utilized	(1,602)
Balance as of December 31, 2019	$	1,222

During the year ended December 31, 2018, the Company incurred a charge of $611 within "Cost of goods sold" in our Rail Products and Services segment related to a commercial decision to support a customer concern related to a previous project.

On March 13, 2019, the Company and its subsidiary, CXT Incorporated entered into a Settlement Agreement (the “Settlement Agreement”) with Union Pacific Railroad (“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, beginning with a $2,000 immediate payment, and with the remaining $48,000 paid in installments over a six-year period commencing on March 13, 2019 through December 2024 pursuant to a Promissory Note. Additionally, commencing in January 2019 and through December 2024, UPRR has agreed to purchase 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 with 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.

54

The expected payments under the UPRR settlement agreement for the year ending December 31, 2020 and thereafter were as follows:

Year Ending December 31,
2020	$	8,000
2021	8,000
2022	8,000
2023	8,000
2024	8,000
Total	$	40,000

The Company reclassified $6,600 of the previously accrued warranty reserve related to the UPRR matter into its aggregate accrued settlement liability of $50,000 as of December 31, 2018. Therefore the Company recognized $43,400 in expense for the year ended December 31, 2018 for the remaining amount per the Settlement Agreement, which was recorded in “Concrete Tie Settlement expense” within our Consolidated Statements of Operations. As of December 31, 2019 and 2018, $8,000 and $10,000 was recorded within “Current portion of accrued settlement,” respectively, and $32,000 and $40,000 was recorded within “Long-term portion of accrued settlement,” respectively, within our Consolidated Balance Sheets.

Other Legal Matters

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 December 31, 2019.

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 December 31, 2019, no such disclosures were considered necessary.

Environmental Matters

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. 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.

The following table sets forth the Company’s undiscounted environmental obligation:

	Environmental Liability
Balance as of December 31, 2018	$	6,128
Additions to environmental obligations	54
Environmental obligations utilized	(114)
Balance as of December 31, 2019	$	6,068

ITEM 9A. 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 Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a–15(e) under the Securities Exchange Act of 1934, as amended (“the Exchange Act”)) as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective at the end of the period covered by this report.

Managements’ Report on Internal Control Over Financial Reporting

The management of L.B. Foster Company is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). L.B. Foster Company’s internal control system is designed to provide reasonable assurance to the Company’s management and Board of Directors regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States. All internal control systems, no matter how well designed, have inherent limitations. Accordingly, even effective controls can provide only reasonable assurance with respect to financial statement preparation and presentation. There were no significant changes in internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the fourth quarter of 2019 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

L.B. Foster Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2019. In making this assessment, management used criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control - Integrated Framework (2013 Framework). Based on this assessment, management concluded that the Company maintained effective internal control over financial reporting as of December 31, 2019.

Ernst & Young LLP, the independent registered public accounting firm that also audited the Company’s consolidated financial statements, has issued an attestation report on the Company’s internal control over financial reporting. Ernst & Young’s attestation report on the Company’s internal control over financial reporting appears in Part II, Item 8 of this Annual Report on Form 10-K and is incorporated herein by reference.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of L.B. Foster Company and Subsidiaries

Opinion on Internal Control over Financial Reporting

We have audited L.B. Foster Company and Subsidiaries’ internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, L.B. Foster Company and Subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2019 and 2018, the related consolidated statements of operations, comprehensive (loss) income, stockholders’ equity and cash flows for each of the two years in the period ended December 31, 2019, and the related notes and the financial statement schedule listed in the index at Item 15(a) and our report dated February 27, 2020 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Managements’ Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

EX-4.1

Exhibit 4.1

DESCRIPTION OF THE REGISTRANT’S SECURITIES

REGISTERED PURSUANT TO SECTION 12 OF THE

SECURITIES EXCHANGE ACT OF 1934

The following is a brief description of the common stock, par value $0.01 per share (“Common Stock”), of the L.B. Foster Company (the “Company”), which is the only security of the Company registered under Section 12 of the Securities Exchange Act of 1934, as amended. The summary of the terms of the Common Stock is not complete and is subject to, and qualified in its entirety by reference to, the relevant provisions of the laws of the Commonwealth of Pennsylvania, including the Pennsylvania Business Corporation Law (“PBCL”), the Company’s Articles of Incorporation (“Articles of Incorporation”) and its Bylaws (the “Bylaws”). Copies of the Articles of Incorporation and Bylaws have been filed with the Securities and Exchange Commission and are incorporated by reference as an exhibit to the Annual Report on Form 10-K of which this Exhibit 4.1 is a part. We encourage you to read our Articles of Incorporation and Bylaws for additional information.

Overview of Capital Stock

Authorized Capital Stock

Our authorized capital shares consist of 20,000,000 shares of Common Stock and 5,000,000 shares of preferred stock (“Preferred Stock”). The Board of Directors of the Company (the “Board of Directors”) may issue Preferred Stock from time to time. Subject to the limits imposed by the PBCL, our Board of Directors is authorized to divide the authorized and unissued shares of Preferred Stock into classes or series, or both, and to determine for any such class or series its designation and the number of shares of the class or series and the voting rights, preferences, limitations and special rights, if any, of the class or series. As of December 31, 2019, no shares of Preferred Stock were registered or outstanding.

Description of Common Stock

Voting Rights

Holders of Common Stock are entitled to one vote per share on all matters voted on by shareholders, including the election of directors. Our Common Stock does not have cumulative voting rights and our Board of Directors is not classified. Except as otherwise provided in the PBCL, Articles of Incorporation or Bylaws, actions by shareholders shall be effective upon the affirmative vote of a majority of the votes cast by all shareholders entitled to vote thereon and, if any shareholders are entitled to vote thereon as a class, upon receiving the affirmative vote of a majority of the votes cast by the shareholders entitled to vote as a class. The Bylaws provide that, in the case of director elections, candidates receiving the highest number of votes from each class or group of classes shall be elected (i.e., plurality vote standard).

Notwithstanding the foregoing, the affirmative vote of no less than two-thirds of the votes that all shareholders are entitled to cast is required to amend certain provisions of the Bylaws regarding (i) advance notice of nominations and proposals (Section 2.05) and (ii) amendment of Bylaws (Section 7.02).

Dividend Rights

Subject to the rights of any Preferred Stock then outstanding, holders of Common Stock are entitled to receive dividends for each outstanding share, if any, as may be declared from time to time by the Board of Directors in its discretion out of funds legally available for the payment of dividends.

Liquidation Rights

In the event of the Company’s liquidation, dissolution, or winding up, either voluntarily or involuntarily, holders of Common Stock are entitled to receive, subject to any liquidation preference of any Preferred Stock then outstanding, the remaining assets of the Company available for distribution, if any, in proportion to the number of shares held.

Other Rights and Preferences

The holders of Common Stock do not have any preemptive, redemption, sinking fund, or conversion rights and the Common Stock is not subject to any restriction on alienability, except as required by law.

Certain Anti-Takeover Provisions

Governance Document Provisions

The Articles of Incorporation and Bylaws include certain provisions which may be considered to be “anti-takeover” in nature because they may have the effect of discouraging or making more difficult the acquisition of control by means of a hostile tender offer, exchange offer, proxy contest or similar transaction. The Company believes these provisions protect shareholders by providing a measure of assurance that shareholders will be treated fairly in the

event of an unsolicited takeover bid and by preventing a successful takeover bidder from exercising its voting control to the detriment of the other shareholders.

The provisions in the Articles of Incorporation and Bylaws (or lack thereof) which may be considered to be “anti-takeover” in nature include the following:

•Availability of authorized but unissued capital stock, including the ability to issue a class or series, or both, of Preferred Stock whose rights and privileges may be determined by the Board of Directors;

•A provision that does not permit shareholders to cumulate their votes for the election of directors;

•A provision that limits the permissible number of directors;

•A provision that requires, in certain circumstances, a greater than majority shareholder vote in order to amend the Bylaws and advance notice provisions set forth therein;

•A provision requiring that advance notice be delivered to the Company of any business to be brought by an eligible shareholder before a meeting of shareholders and requiring certain procedures to be followed by shareholders in nominating candidates for election as directors;

•No provision for shareholders to call special meetings of shareholders; and

•No provision for shareholders to act by partial written consent.

Pennsylvania Business Corporation Law Provisions

The PBCL contains a number of statutory “anti-takeover” provisions, including Subchapters E, F, G and H of Chapter 25 and Sections 2521, 2524 and 2538 of the PBCL, which apply automatically to Pennsylvania registered corporations unless the corporation elects to opt-out of those provisions. The Company is a Pennsylvania registered corporation, and has elected to opt-out of certain provisions as described below. Descriptions of the anti-takeover provisions that the Company opted out of are qualified in their entirety by reference to the PBCL:

•Section 1715 (relating to exercise of powers generally) provides that the board of directors, when considering the best interests of the corporation generally, may consider the effects of an action upon any or all groups affected by the action, the short- and long-term interests of the corporation, and the resources, intent, and conduct of any person seeking to acquire control of the corporation. In considering the best interests of the corporation and the effect of an action, the board of directors shall not be required to regard the corporate interest or interest of any particular group as the dominant or controlling interest, and the act of the board of directors, absent any breach of fiduciary duty, shall be presumed to be in the best interest of the corporation.

•Section 2538 of the PBCL generally establishes certain shareholder approval requirements with respect to specified transactions with “interested shareholders.”

•Subchapter E (relating to control transactions) generally provides that if any person or group acquires 20% or more of the Company’s voting power, the remaining holders of voting shares may demand from such person or group the fair value of their voting shares, including a proportionate amount of any control premium.

•Subchapter F (relating to business combinations) imposes conditions upon “business combinations,” including a five-year moratorium on certain “business combinations” unless certain conditions are met, between an “interested shareholder” and the Company. The term “business combination” is defined broadly to include various transactions between a corporation and an interested shareholder including mergers, sales or leases of specified amounts of assets, liquidations, reclassifications and issuances of specified amounts of additional shares of stock of the corporation. An “interested shareholder” is defined generally as the beneficial owner of at least 20% of a corporation’s voting shares.

•Subchapter G (relating to control share acquisitions) generally requires a shareholder vote to reinstate voting rights to control shares acquired by a 20% shareholder in a control-share acquisition.

•Subchapter H (relating to disgorgement of profits) generally requires a person or group that owns 20% or more of a company’s equity securities, or that publicly announces an intention to acquire control of a company, to disgorge within 24 months prior to, or within 18 months after, acquiring control status any profits received from a sale of the company’s shares.

Leases [Abstract]

Leases

Leases

On January 1, 2019, the Company adopted ASU 2016-02 and all related amendments using the modified retrospective approach, which resulted in an increase in assets of $13,585 and an increase in current and long-term liabilities of $3,322 and $10,263, respectively. This adoption did not affect the Company’s results of operations or cash flows.

The Company determines if an arrangement is a lease at its inception. Operating leases are included in “Operating lease right-of-use assets,” “Other current liabilities,” and “Long-term operating lease liabilities” within the Company’s 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 Company’s Consolidated Balance Sheets.

Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of the lease payments. The Company uses the implicit rate when readily determinable. The operating lease right-of-use asset also includes indirect costs incurred and lease payments made prior to the commencement date, less any lease incentives received. The Company’s lease terms may include options to extend or terminate the lease and will be recognized when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

The Company has lease agreements with lease and non-lease components that it accounts for as a single lease component. Also, for certain equipment leases, the Company applies a portfolio approach to effectively account for the operating lease right-of-use assets and liabilities.

Finance lease and lessor accounting recognition has remained substantially unchanged under ASU 2016-02. The adoption of ASU 2016-02 had no impact on the Company’s balance sheet, results of operations, or cash flows for finance leases.

The Company has operating and finance leases for manufacturing facilities, corporate offices, sales offices, vehicles, and certain equipment. As of December 31, 2019, its leases had remaining lease terms of 1 to 12 years, some of which include options to extend the leases for up to 12 years, and some of which include options to terminate the leases within 1 year. As of December 31, 2019, the Company’s operating leases had a weighted average remaining lease term of 7 years and a weighted average discount rate of 5.1%. As of December 31, 2019, the Company’s finance leases had a weighted average remaining lease term of 1 year and a weighted average discount rate of 4.3%.

The balance sheet components of the Company’s leases were as follows as of December 31, 2019:

	December 31, 2019

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2019

Accounting Policies [Abstract]

Organization, operations, and basis of consolidations

Organization, operations, and basis of consolidation

The consolidated financial statements include the accounts of L.B. Foster Company and its wholly-owned subsidiaries, joint ventures, and partnerships in which a controlling interest is held. Inter-company transactions and accounts have been eliminated. The Company utilizes the equity method of accounting for companies where its ownership is less than or equal to 50% and significant influence exists.

L.B. Foster Company (“Company”) is a leading manufacturer and distributor of products and service provider for transportation and energy infrastructure with locations in North America and Europe. The Company is organized and operates in three business segments: Rail Products and Services (“Rail”), Construction Products (“Construction”), and Tubular and Energy Services (“Tubular and Energy”). The Rail segment is comprised of several manufacturing and distribution businesses that provide a variety of products and services for freight and passenger railroads and industrial companies throughout the world. The Construction segment is composed of piling, fabricated bridge, and precast concrete product offerings across North America. The Tubular and Energy segment provides products and services predominantly to the U.S. mid and upstream oil and gas markets.

Cash and cash equivalents

Cash and cash equivalents

The Company considers cash and other instruments with maturities of three months or less when purchased to be cash and cash equivalents. The Company invests available funds in a manner to maximize returns, preserve investment principal, and maintain liquidity, while seeking the highest yield available.

Cash and cash equivalents held in non-domestic accounts were $13,660 and $8,058 as of December 31, 2019 and 2018, respectively. Included in non-domestic cash equivalents are investments in bank term deposits of approximately $17 and $16 as of December 31, 2019 and 2018, respectively. The carrying amounts approximated fair value due to the short maturity of the instruments.

Inventory

Inventory

Inventory is valued at the lower of average cost or net realizable value. Slow-moving inventory is reviewed and adjusted regularly, based upon product knowledge, physical inventory observation, inventory turnover, and the age of the inventory. Inventory contains product costs, including inbound freight, direct labor, overhead costs relating to the manufacturing and distribution of products, and absorption costs representing the excess manufacturing or production costs over the amounts charged to the cost of sales or services.

Property, plant and equipment

Property, plant, and equipment

Depreciation and amortization are provided on a straight-line basis over the estimated useful lives of 7 to 40 years for buildings and 2 to 13 years for machinery and equipment. Leasehold improvements are amortized over 6 to 10 years, which represent the lives of the respective leases or the lives of the improvements, whichever is shorter. Depreciation expense is recorded within “Cost of goods sold,” “Cost of services sold,” and “Selling and administrative expenses” on the Consolidated Statements of Operations based upon the particular asset’s use. The Company reviews a long-lived asset for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The Company recognizes an impairment loss if the carrying amount of a long-lived asset is not recoverable and exceeds its fair value. There were no property, plant, and equipment impairments recorded for the years ended December 31, 2019 and 2018.

Maintenance, repairs, and minor renewals are charged to operations as incurred. Major renewals and betterments that substantially extend the useful life of the property are capitalized at cost. Upon sale or other disposition of assets, the costs and related accumulated depreciation and amortization are removed from the accounts and the resulting gain or loss, if any, is reflected in “Other income or expense.”

Allowance for doubtful accounts

Allowance for doubtful accounts

The allowance for doubtful accounts is recorded to reflect the estimated realization of the Company’s accounts receivable and includes assessments of the probability of collection and the credit-worthiness of certain customers. Reserves for uncollectible accounts are recorded as part of “Selling and administrative expenses” on the Consolidated Statements of Operations. The Company reviews its accounts receivable aging and calculates an allowance through application of historic reserve factors to overdue receivables. This calculation is supplemented by specific account reviews performed by the Company’s credit department. As

necessary, the application of the Company’s allowance rates to specific customers is reviewed and adjusted to more accurately reflect the credit risk inherent within that customer relationship.

Goodwill and other intangible assets

Goodwill and other intangible assets

Goodwill is the cost of an acquisition less the fair value of the identifiable net assets of the acquired business. Goodwill is tested annually for impairment or more often if there are indicators of impairment within a reporting unit. A reporting unit is an operating segment or a component of an operating segment for which discrete financial information is available and reviewed by management on a regular basis. The goodwill impairment test involves comparing the fair value of a reporting unit to its carrying value, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss equal to the excess amount up to the goodwill balance is recorded as a component of operations. The Company performs its annual impairment tests in the fourth quarter.

The Company’s fourth quarter 2019 annual test included the assessment of qualitative factors to determine whether it was more likely than not that the fair value of each reporting unit is less than its carrying value. The qualitative assessment encompassed a review of events and circumstances specific to each reporting unit with goodwill, as well as specific to the entity as a whole. The Company’s qualitative assessment considered, among other things, factors such as macroeconomic conditions, industry and market considerations, including changes in the Company’s stock price and market multiples, projected financial performance, cost factors, changes in carrying values, and other relevant factors. Considering the totality of the qualitative factors assessed, based on the weight of evidence, no circumstances existed that would indicate it was more likely than not that goodwill was impaired. There was no goodwill impairment recognized during 2019 or 2018. The Company continues to monitor the recoverability of the long-lived assets associated with certain reporting units of the Company and the long-term financial projections of the businesses. Sustained declines in the markets we serve may result in future long-lived asset impairment.

The Company has no indefinite-lived intangible assets. The Company reviews a long-lived intangible asset for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. All intangible assets are amortized over their estimated useful lives.

Environmental and remediation and compliance

Environmental remediation and compliance

Environmental remediation costs are accrued when the liability is probable and costs are estimable. Environmental compliance costs, which principally include the disposal of waste generated by routine operations, are expensed as incurred. Capitalized environmental costs, when appropriate, are depreciated over their useful life. Reserves are not reduced by potential claims for recovery and are not discounted. Claims for recovery are recognized as agreements are reached with third parties or as amounts are received. Reserves are periodically reviewed throughout the year and adjusted to reflect current remediation progress, prospective estimates of required activity, and other factors that may be relevant, including changes in technology or regulations. See Note 18 for additional information regarding the Company’s outstanding environmental and litigation reserves.

Revenue recognition

Revenue recognition

The Company’s revenues are comprised of product and service sales, including products and services provided under long-term agreements with its customers. All revenue is recognized when the Company satisfies its performance obligations under the contract, either implicit or explicit, by transferring the promised product or rendering a service to its customer either when or as its customer obtains control of the product or the service is rendered. Deferred revenue consists of customer billings or payments received for which the revenue recognition criteria have not yet been met as well as contract liabilities (billings in excess of costs) on over time contracts. Advance payments from customers typically relate to contracts for which the Company has significantly fulfilled its obligations, but due to the Company’s continuing involvement with the project, revenue is precluded from being recognized until the performance obligation is met for the customer. See Note 3 for additional information.

Product warranty

Product warrantyThe Company maintains a current warranty liability for the repair or replacement of defective products. For certain manufactured products, an accrual is made on a monthly basis as a percentage of cost of sales based upon historical experience. For long-lived construction products, a warranty is established when the claim is known and quantifiable. The product warranty accrual is periodically adjusted based on the identification or resolution of known individual product warranty claims or due to changes in the Company’s historical warranty experience.

Income taxes

Income taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. Deferred taxes are measured using enacted tax laws and rates expected to be in effect when such differences are recovered or settled. The effect of a change in tax rates on deferred taxes is recognized in income in the period that includes the enactment date of the change. The Company has also elected to record global intangible low-taxed income (“GILTI”) as period costs if and when incurred.

The Company makes judgments regarding the recognition of deferred tax assets and the future realization of these assets. As prescribed by the Financial Accounting Standards Board’s (“FASB”) Accounting Standard Codification (“ASC”) 740, “Income Taxes” and applicable guidance, valuation allowances must be provided for those deferred tax assets for which it is more likely than not (a likelihood of more than 50%) that some portion or all of the deferred tax assets will not be realized. The guidance requires the Company to evaluate positive and negative evidence regarding the recoverability of deferred tax assets. The determination of whether the positive evidence outweighs the negative evidence and quantification of the valuation allowance requires the Company to make estimates and judgments of future financial results. The Company has concluded that for purposes of quantifying valuation allowances, it would be appropriate to consider the reversal of taxable temporary differences related to indefinite-lived intangible assets when assessing the realizability of deferred tax assets that upon reversal, would give rise to operating losses that do not expire.

The Company evaluates all tax positions taken on its federal, state, and foreign tax filings to determine if the position is more likely than not to be sustained upon examination. For positions that meet the more likely than not to be sustained criteria, the largest amount of benefit to be realized upon ultimate settlement is determined on a cumulative probability basis. A previously recognized tax position is derecognized when it is subsequently determined that a tax position no longer meets the more likely than not threshold to be sustained. The evaluation of the sustainability of a tax position and the expected tax benefit is based on judgment, historical experience, and various other assumptions. Actual results could differ from those estimates upon subsequent resolution of identified matters. The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes.

Foreign currency translation

Foreign currency translationThe assets and liabilities of our foreign subsidiaries are measured using the local currency as the functional currency and are translated into U.S. dollars at exchange rates as of the balance sheet date. Income statement amounts are translated at the weighted-average rates of exchange during the year. The translation adjustment is accumulated as a separate component of “Accumulated other comprehensive loss” within our Consolidated Balance Sheets.

Research and development

Research and developmentThe Company expenses research and development costs as costs are incurred.

Reclassifications

Reclassifications

Certain accounts in the prior year consolidated financial statements have been reclassified for comparative purposes principally to conform to the presentation in the current year period.

Recently issued accounting standards

Recently issued accounting guidance

In August 2018, the FASB issued Accounting Standards Update (“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 is a service contract. The amendments in ASU 20118-15 are effective for fiscal years beginning after December 15, 2019 and for interim periods therein with early adoption permitted. The Company evaluated the potential impact of ASU 2018-15 on its consolidated financial position, results of operations, and cash flows and anticipates the adoption will have an immaterial effect on the Company’s Consolidated Financial Statements.

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. 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 will need to measure expected credit losses on assets that have a low risk of loss. The new standard will become effective for the Company January 1, 2020 and will be applied using the modified retrospective basis. The Company anticipates the adoption of this standard will not have a material impact on the Company’s Consolidated Financial Statements.

Recently adopted accounting guidance

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The new accounting requirements include the accounting for, presentation of, and classification of leases. The guidance resulted in most leases being capitalized as a right-of-use asset with a related balance sheet liability. The requirements of the new standard are effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. The Company adopted the provisions of ASU 2016-02 on January 1, 2019, using the modified retrospective approach as of the beginning of the period of adoption. Additionally, the Company has elected to apply the practical expedients for leases that commenced prior to the effective date, not to apply the recognition requirements in the standard to short-term leases, and not to separate non-lease components from lease components. The Company has presented the disclosures required by ASU 2016-02 in Note 8.

In February 2018, the FASB issued ASU 2018-02, “Income Statement – Reporting Comprehensive Income; Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”), which allows companies to reclassify stranded tax effects caused by the U.S. Tax Cuts and Jobs Act (the “Tax Act”) from accumulated other comprehensive income to retained earnings. The amendments eliminate the stranded tax effects resulting from the Tax Act and improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The Company adopted ASU 2018-02 during the first quarter of 2019 and has chosen to record the reclassification as of the beginning of the period of adoption. As a result of adopting this standard, we reclassified stranded tax effects of $633 from “Accumulated other comprehensive loss” to “Retained earnings.”

Expected rate of return on plan assets	5.9	%	5.9	%

The expected long-term rate of return is based on numerous factors, including the target asset allocation for plan assets, historical rate of return, long-term inflation assumptions, and current and projected market conditions.

Amounts applicable to the Company’s pension plan with accumulated benefit obligations in excess of plan assets were as follows as of December 31, 2019 and 2018:

	December 31,
	2019		2018
Projected benefit obligation	$	7,809	$	16,717
Accumulated benefit obligation	7,809		16,717
Fair value of plan assets	4,360		12,468

Plan assets consist primarily of various fixed income and equity investments. The Company’s primary investment objective is to provide long-term growth of capital while accepting a moderate level of risk. The investments are limited to cash and cash equivalents, bonds, preferred stocks, and common stocks. The investment target ranges and actual allocation of pension plan assets by major category as of December 31, 2019 and 2018 were as follows:

		December 31,
	Target	2019		2018
Asset Category
Cash and cash equivalents	0 - 20%	19	%	3	%
Total fixed income funds	25 - 50%	30		28
Total mutual funds and equities	35 - 70%	51		69
Total		100	%	100	%

In accordance with the fair value disclosure requirements of ASC 820, “Fair Value Measurements and Disclosures,” the following assets were measured at fair value on a recurring basis as of December 31, 2019 and 2018. Additional information regarding ASC 820 and the fair value hierarchy can be found in Note 18.

Exchange-traded funds	1,513		6,711
Total mutual funds and equities	2,207		8,592
Total	$	4,360	$	12,468

Cash equivalents: The Company uses quoted market prices to determine the fair value of these investments in interest-bearing cash accounts and they are classified as Level 1 of the fair value hierarchy. The carrying amounts approximate fair value because of the short maturity of the instruments.

Fixed income funds: Investments within the fixed income funds category consist of fixed income corporate debt. The Company uses quoted market prices to determine the fair values of these fixed income funds. These instruments consist of exchange-traded government and corporate bonds and are classified as Level 1 of the fair value hierarchy.

Equity funds and equities: The valuation of investments in registered investment companies is based on the underlying investments in securities. Securities traded on security exchanges are valued at the latest quoted sales price. Securities traded in the over-the-counter market and listed securities for which no sale was reported on that date are valued at the average of the last reported bid and ask quotations. These investments are classified as Level 1 of the fair value hierarchy.

The Company currently anticipates contributions of $660 to its United States defined benefit plan in 2020.

The following benefit payments are expected to be paid during the years indicated:

The Company has estimated the long-term rate of return on plan assets based primarily on historical returns on plan assets, adjusted for changes in target portfolio allocations, and recent changes in long-term interest rates based on publicly available information.

Plan assets are invested by the trustees in accordance with a written statement of investment principles. This statement permits investment in equities, corporate bonds, United Kingdom government securities, commercial property, and cash, based on certain target allocation percentages. Asset allocation is primarily based on a strategy to provide steady growth without undue fluctuations. The target asset allocation percentages for 2019 were as follows:

	Portec Rail
	Plan
Equity securities	Up to 100%
Commercial property	Not to exceed 50%
U.K. Government securities	Not to exceed 50%
Cash	Up to 100%

Plan assets held within the United Kingdom defined benefit plan consist of cash and equity securities that have been classified as Level 1 of the fair value hierarchy. All other plan assets have been classified as Level 2 of the fair value hierarchy.

The plan assets by category for the years ended December 31, 2019 and 2018 were as follows:

The expense related to this plan was not material for 2019 or 2018. The accrued benefit obligation was $840 and $724 as of December 31, 2019 and 2018, respectively. This obligation is recognized within “Other long-term liabilities” on the Consolidated Balance Sheets. During 2018, the plan recognized a curtailment gain of $113. Benefit payments anticipated for 2020 are not material.

The weighted average assumptions in the following table represent the rates used to develop the actuarial present value of the projected benefit obligation for the year listed and also the net periodic benefit cost for the following year.

Stock-based Compensation

12 Months Ended

Dec. 31, 2019

Share-based Compensation [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 period. Stock forfeitures and cancellations are recognized as they occur. The Company recorded stock-based compensation expense of $3,155 and $3,836 for the years ended December 31, 2019 and 2018, respectively, related to fully-vested stock awards, restricted stock awards, and performance unit awards. As of December 31, 2019, unrecognized compensation expense for awards the Company expects to vest approximated $3,576. The Company will recognize this unrecognized compensation expense over approximately 3.2 years.

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

As of December 31, 2019, the Company had stock awards issued pursuant to the 2006 Omnibus Incentive Plan, as amended and restated in May 2018 (“Omnibus Plan”). The Omnibus Plan allows for the issuance of 2,058,000 shares of common stock through the granting of stock options or stock awards (including performance units convertible into stock) to key employees and directors at no less than 100% of fair market value on the date of the grant. The Omnibus Plan provides for the granting of “nonqualified options” with a duration of not more than ten years from the date of grant. The Omnibus Plan also provides that, unless otherwise set forth in the option agreement, stock options are exercisable in installments of up to 25% annually beginning one year from the date of grant. No stock options have been granted under the Omnibus Plan and, as such, there was no stock-based compensation expense related to stock options recorded in 2019 or 2018.

Non-Employee Director Fully-Vested and Restricted Stock Awards

Prior to May 2018, non-employee directors were awarded fully-vested shares of the Company’s common stock on each date the non-employee directors were elected at the annual shareholders’ meeting to serve as directors. Since May 2018, such annual equity awards have been subject to a one-year vesting requirement. During the quarter ended June 30, 2017, the Nomination and Governance Committee and Board of Directors jointly approved the Deferred Compensation Plan for Non-Employee Directors under the Omnibus Plan, which permits non-employee directors of the Company to defer receipt of earned cash and/or stock compensation for service on the Board.

The non-employee directors were granted a total of 21,532 and 24,427 fully-vested and restricted shares for the years ended December 31, 2019 and 2018, respectively. Compensation expense recorded by the Company related to such awards to non-employee directors was approximately $526 and $880 for the years ended December 31, 2019 and 2018, respectively. During 2019, 12,304 deferred share units were allotted to the accounts of the non-employee directors pursuant to the Deferred Compensation Plan for Non-Employee Directors.

The weighted average fair value of all the fully-vested and restricted stock grants awarded was $24.38 and $23.64 per share for the years ended December 31, 2019 and 2018, respectively.

Restricted Stock Awards and Performance Unit Awards

Under the Omnibus Plan, the Company grants certain employees restricted stock and performance unit awards. The forfeitable restricted stock awards granted prior to March 2015 generally time-vest after a four-year period, and those granted subsequent to March 2015 generally time-vest ratably over a three-year period, unless indicated otherwise by the underlying restricted stock award agreement. Performance unit awards are offered annually under separate three-year long-term incentive programs. Performance units are subject to forfeiture and will be converted into common stock 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 stock awards expected to vest changes in a subsequent accounting period, cumulative compensation expense could increase or decrease. The change is recognized in the current period for the performance unit awards and would change future expense over the remaining service period.

The following table summarizes the restricted stock award, deferred stock units, and performance unit award activity for the years ended December 31, 2019 and 2018:

	Restricted Stock	Deferred Stock Units	Performance Stock Units	Weighted Average Aggregate Grant Date Fair Value
Outstanding as of January 1, 2018	186,806	26,860	181,341	$	16.53

Outstanding as of December 31, 2019	150,799	54,078	331,148	$	18.50

Performance 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 plan. Performance Stock Units are adjusted to the Company’s expected performance target attainment, while the aggregate fair value in the above table is based upon achieving 100% of the performance targets as defined in the underlying plan.

Excluding the fully-vested and restricted stock awards granted to non-employee directors, the Company recorded stock-based compensation expense of $2,630 and $2,956, respectively, for the periods ended December 31, 2019 and 2018 related to restricted stock and performance unit awards.

Revenue from Contract with Customer [Abstract]

Revenue

Revenue

The Company’s revenues are comprised of product and service sales, including products and services provided under long-term agreements with its customers. All revenue is recognized when the Company satisfies its performance obligations under the contract, either implicit or explicit, by transferring the promised product or rendering a service to its customer either when or as its customer obtains control of the product or as the service is rendered. A performance obligation is a promise in a contract to transfer a distinct product or render a specific service to a customer. A contract’s transaction price is allocated to each distinct performance obligation. The majority of the Company’s contracts have a single performance obligation, as the promise to transfer products or render services is not separately identifiable from other promises in the contract and, therefore, not distinct. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or providing services. Revenue is recorded net of returns, allowances, customer discounts, and incentives. Sales, value added, and other taxes collected from customers and remitted to governmental authorities are accounted for on a net (excluded from revenues) basis. Shipping and handling costs are included in cost of goods sold.

The Company’s performance obligations under long-term agreements with its customers are generally satisfied as over time. Over time revenue is primarily comprised of transit infrastructure projects within Rail Products and Rail Technologies, long-term bridge projects within Piling and Fabricated Bridge Products, precast concrete buildings within Precast Concrete Products, and custom precision metering systems within Protective Coatings and Measurement Systems. Revenue from products or services provided to customers over time accounted for 28.5% and 26.0% of revenue for the years ended December 31, 2019 and 2018, 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 $136,014 and $121,919 for the years ended December 31, 2019 and 2018, 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 $50,761 and $41,334 for the years ended December 31, 2019 and 2018, respectively. As of December 31, 2019 and 2018, the Company had contract assets of $37,032 and $26,692, respectively, that were recorded in “Inventories - net” within the Consolidated Balance Sheets. As of December 31, 2019 and 2018, the Company had contract liabilities of $4,472 and $1,505, respectively, that were recorded in “Deferred revenue” within the Consolidated Balance Sheets.

Accounting for these long-term agreements involves the use of various techniques to estimate total revenues and costs. The Company estimates profit on these long-term agreements as the difference between total estimated revenues and expected costs to complete a contract and recognizes that profit over the life of the contract. Contract estimates are based on various assumptions to project the outcome of future events that may span several years. These assumptions include, among other things, labor productivity, cost and availability of materials, and timing of funding by customers. The nature of these long-term agreements may give rise to several types of variable consideration, such as claims, awards, and incentive fees. Historically, these amounts of variable consideration have not been considered significant. Contract estimates may include additional revenue for submitted contract modifications if there exists an enforceable right to the modification, the amount can be reasonably estimated, and its realization is probable. These estimates are based on historical collection experience, anticipated performance, and the Company’s best judgment at

that time. These amounts are generally included in the contract’s transaction price and are allocated over the remaining performance obligations. Changes in judgments related to the estimates above could impact the timing and amount of revenue recognized and, accordingly, the timing and amount of associated income. In the event that a contract loss becomes known, the entire amount of the estimated loss is recognized in the Consolidated Statements of Operations.

The majority of the Company’s revenue is from products transferred and services rendered to customers at a point in time, which is inherent in all major product and service categories. Point in time revenue accounted for 71.5% and 74.0% of revenue for the years ended December 31, 2019 and 2018, respectively. The Company recognizes revenue at the point in time in which the customer obtains control of the product or service, which is generally when 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 designated physical location.

The following table summarizes the Company’s net sales by major product and service category:

	December 31,
	2019		2018
Rail Products	$	194,464	$	188,590
Rail Technologies	127,344		130,934

Total net sales	$	655,057	$	626,969

For the years ended December 31, 2019 and 2018, net sales by the timing of the transfer of goods and services are as follows:

Year ended December 31, 2019	Rail Products and Services		Construction Products		Tubular and Energy Services		Total
Point in time	$	240,047	$	115,590	$	112,645	$	468,282
Over time	81,761		66,896		38,118		186,775
Total net sales	$	321,808	$	182,486	$	150,763	$	655,057
Year ended December 31, 2018	Rail Products and Services		Construction Products		Tubular and Energy Services		Total
Point in time	$	232,814	$	106,168	$	124,734	$	463,716
Over time	86,710		52,485		24,058		163,253
Total net sales	$	319,524	$	158,653	$	148,792	$	626,969

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 Consolidated Balance Sheets.

Significant changes in contract assets during the year ended December 31, 2019 and 2018 included transfers to receivables from contract assets recognized at the beginning of the period of $24,487 and $18,941, respectively. Significant changes in contract liabilities during the year ended December 31, 2019 and 2018 included increases of $4,358 and $1,447, respectively, 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 year ended December 31, 2019 and 2018 of $1,462 and $1,141, respectively, that were included in the contract liabilities at the beginning of the respective period.

As of December 31, 2019, the Company had approximately $230,067 of remaining performance obligations, which is also referred to as backlog. Approximately 8.3% of the backlog as of December 31, 2019 was related to projects that are anticipated to extend beyond December 31, 2020.

Deferred RevenueDeferred revenue of $8,446 and $6,619 as of December 31, 2019 and 2018, respectively, consists of customer billings or payments received for which the revenue recognition criteria have not yet been met as well as contract liabilities (billings in excess of costs) on over time revenue projects. As of December 31, 2019 and 2018, contract liabilities, recorded within “Deferred revenue,” was $4,472 and $1,505, respectively. Advanced payments from customers typically relate to contracts with respect to which the Company has significantly fulfilled its obligations, but due to the Company’s continuing involvement with the project, revenue is not recognized until title, ownership, and risk of loss have passed to the customer.

Fair Value Measurements

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.

The Company has an established process for determining fair value for its financial assets and liabilities, principally cash and cash equivalents and interest rate swaps. Fair value is based on quoted market prices, where available. If quoted market prices are not available, fair value is based on assumptions that use as inputs market-based parameters. The following section describes the valuation methodologies used by the Company to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which each instrument is generally classified. Where appropriate, the description includes details of the key inputs to the valuations and any significant assumptions.

Cash equivalents. Included within “Cash and cash equivalents” 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 swaps became effective in February 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. 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 have been classified as Level 2 within the fair value hierarchy. When the interest rate swap fair market value is in an asset position, they are recorded in “Other current assets” and when in a liability position, they are recorded in “Other accrued liabilities” within our Consolidated Balance Sheets.

The following assets and liabilities of the Company were measured at fair value on a recurring basis subject to the disclosure requirements of ASC 820, “Fair Value Measurement,” as of December 31, 2019 and 2018:

	Fair Value Measurements as of December 31, 2019								Fair Value Measurements as of December 31, 2018
	December 31, 2019		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		December 31, 2018		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Term deposits	$	17	$	17	$	—	$	—	$	16	$	16	$	—	$	—
Interest rate swaps	—		—		—		—		675		—		675		—

Total liabilities	$	480	$	—	$	480	$	—	$	—	$	—	$	—	$	—

The interest rate swaps 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 domestic debt. Therefore, the gains and losses related to the interest rate swaps are reclassified from “Accumulated other comprehensive loss” and included in “Interest expense - net” in our Consolidated Statements of Operations. For the year ended December 31, 2019 and 2018, interest income from interest rate swaps was $114 and $34, respectively.

The gross carrying value of the Company’s revolving credit facility approximates fair value for the periods presented. Additional information regarding the revolving credit facility can be found in Note 10.

Information regarding the fair value disclosures associated with the assets of the Company’s defined benefit plans can be found in Note 16.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Organization, operations, and basis of consolidation

The consolidated financial statements include the accounts of L.B. Foster Company and its wholly-owned subsidiaries, joint ventures, and partnerships in which a controlling interest is held. Inter-company transactions and accounts have been eliminated. The Company utilizes the equity method of accounting for companies where its ownership is less than or equal to 50% and significant influence exists.

L.B. Foster Company (“Company”) is a leading manufacturer and distributor of products and service provider for transportation and energy infrastructure with locations in North America and Europe. The Company is organized and operates in three business segments: Rail Products and Services (“Rail”), Construction Products (“Construction”), and Tubular and Energy Services (“Tubular and Energy”). The Rail segment is comprised of several manufacturing and distribution businesses that provide a variety of products and services for freight and passenger railroads and industrial companies throughout the world. The Construction segment is composed of piling, fabricated bridge, and precast concrete product offerings across North America. The Tubular and Energy segment provides products and services predominantly to the U.S. mid and upstream oil and gas markets.

Use of estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates, judgements, and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates and changes in these estimates are recorded when known.

Significant accounting policies

Cash and cash equivalents

The Company considers cash and other instruments with maturities of three months or less when purchased to be cash and cash equivalents. The Company invests available funds in a manner to maximize returns, preserve investment principal, and maintain liquidity, while seeking the highest yield available.

Cash and cash equivalents held in non-domestic accounts were $13,660 and $8,058 as of December 31, 2019 and 2018, respectively. Included in non-domestic cash equivalents are investments in bank term deposits of approximately $17 and $16 as of December 31, 2019 and 2018, respectively. The carrying amounts approximated fair value due to the short maturity of the instruments.

Inventory

Inventory is valued at the lower of average cost or net realizable value. Slow-moving inventory is reviewed and adjusted regularly, based upon product knowledge, physical inventory observation, inventory turnover, and the age of the inventory. Inventory contains product costs, including inbound freight, direct labor, overhead costs relating to the manufacturing and distribution of products, and absorption costs representing the excess manufacturing or production costs over the amounts charged to the cost of sales or services.

Property, plant, and equipment

Depreciation and amortization are provided on a straight-line basis over the estimated useful lives of 7 to 40 years for buildings and 2 to 13 years for machinery and equipment. Leasehold improvements are amortized over 6 to 10 years, which represent the lives of the respective leases or the lives of the improvements, whichever is shorter. Depreciation expense is recorded within “Cost of goods sold,” “Cost of services sold,” and “Selling and administrative expenses” on the Consolidated Statements of Operations based upon the particular asset’s use. The Company reviews a long-lived asset for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The Company recognizes an impairment loss if the carrying amount of a long-lived asset is not recoverable and exceeds its fair value. There were no property, plant, and equipment impairments recorded for the years ended December 31, 2019 and 2018.

Maintenance, repairs, and minor renewals are charged to operations as incurred. Major renewals and betterments that substantially extend the useful life of the property are capitalized at cost. Upon sale or other disposition of assets, the costs and related accumulated depreciation and amortization are removed from the accounts and the resulting gain or loss, if any, is reflected in “Other income or expense.”

Allowance for doubtful accounts

The allowance for doubtful accounts is recorded to reflect the estimated realization of the Company’s accounts receivable and includes assessments of the probability of collection and the credit-worthiness of certain customers. Reserves for uncollectible accounts are recorded as part of “Selling and administrative expenses” on the Consolidated Statements of Operations. The Company reviews its accounts receivable aging and calculates an allowance through application of historic reserve factors to overdue receivables. This calculation is supplemented by specific account reviews performed by the Company’s credit department. As

necessary, the application of the Company’s allowance rates to specific customers is reviewed and adjusted to more accurately reflect the credit risk inherent within that customer relationship.

Goodwill and other intangible assets

Goodwill is the cost of an acquisition less the fair value of the identifiable net assets of the acquired business. Goodwill is tested annually for impairment or more often if there are indicators of impairment within a reporting unit. A reporting unit is an operating segment or a component of an operating segment for which discrete financial information is available and reviewed by management on a regular basis. The goodwill impairment test involves comparing the fair value of a reporting unit to its carrying value, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss equal to the excess amount up to the goodwill balance is recorded as a component of operations. The Company performs its annual impairment tests in the fourth quarter.

The Company’s fourth quarter 2019 annual test included the assessment of qualitative factors to determine whether it was more likely than not that the fair value of each reporting unit is less than its carrying value. The qualitative assessment encompassed a review of events and circumstances specific to each reporting unit with goodwill, as well as specific to the entity as a whole. The Company’s qualitative assessment considered, among other things, factors such as macroeconomic conditions, industry and market considerations, including changes in the Company’s stock price and market multiples, projected financial performance, cost factors, changes in carrying values, and other relevant factors. Considering the totality of the qualitative factors assessed, based on the weight of evidence, no circumstances existed that would indicate it was more likely than not that goodwill was impaired. There was no goodwill impairment recognized during 2019 or 2018. The Company continues to monitor the recoverability of the long-lived assets associated with certain reporting units of the Company and the long-term financial projections of the businesses. Sustained declines in the markets we serve may result in future long-lived asset impairment.

The Company has no indefinite-lived intangible assets. The Company reviews a long-lived intangible asset for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. All intangible assets are amortized over their estimated useful lives. There were no definite-lived intangible asset impairments during the years ended December 31, 2019 and 2018.

Environmental remediation and compliance

Environmental remediation costs are accrued when the liability is probable and costs are estimable. Environmental compliance costs, which principally include the disposal of waste generated by routine operations, are expensed as incurred. Capitalized environmental costs, when appropriate, are depreciated over their useful life. Reserves are not reduced by potential claims for recovery and are not discounted. Claims for recovery are recognized as agreements are reached with third parties or as amounts are received. Reserves are periodically reviewed throughout the year and adjusted to reflect current remediation progress, prospective estimates of required activity, and other factors that may be relevant, including changes in technology or regulations. See Note 18 for additional information regarding the Company’s outstanding environmental and litigation reserves.

Revenue recognition

The Company’s revenues are comprised of product and service sales, including products and services provided under long-term agreements with its customers. All revenue is recognized when the Company satisfies its performance obligations under the contract, either implicit or explicit, by transferring the promised product or rendering a service to its customer either when or as its customer obtains control of the product or the service is rendered. Deferred revenue consists of customer billings or payments received for which the revenue recognition criteria have not yet been met as well as contract liabilities (billings in excess of costs) on over time contracts. Advance payments from customers typically relate to contracts for which the Company has significantly fulfilled its obligations, but due to the Company’s continuing involvement with the project, revenue is precluded from being recognized until the performance obligation is met for the customer. See Note 3 for additional information.

Product warranty

The Company maintains a current warranty liability for the repair or replacement of defective products. For certain manufactured products, an accrual is made on a monthly basis as a percentage of cost of sales based upon historical experience. For long-lived construction products, a warranty is established when the claim is known and quantifiable. The product warranty accrual is periodically adjusted based on the identification or resolution of known individual product warranty claims or due to changes in the Company’s historical warranty experience. As of December 31, 2019 and 2018, the product warranty reserve was $1,222 and $2,057, respectively. See Note 18 for additional information regarding the product warranty.

Income taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. Deferred taxes are measured using enacted tax laws and rates expected to be in effect when such differences are recovered or settled. The effect of a change in tax rates on deferred taxes is recognized in income in the period that includes the enactment date of the change. The Company has also elected to record global intangible low-taxed income (“GILTI”) as period costs if and when incurred.

The Company makes judgments regarding the recognition of deferred tax assets and the future realization of these assets. As prescribed by the Financial Accounting Standards Board’s (“FASB”) Accounting Standard Codification (“ASC”) 740, “Income Taxes” and applicable guidance, valuation allowances must be provided for those deferred tax assets for which it is more likely than not (a likelihood of more than 50%) that some portion or all of the deferred tax assets will not be realized. The guidance requires the Company to evaluate positive and negative evidence regarding the recoverability of deferred tax assets. The determination of whether the positive evidence outweighs the negative evidence and quantification of the valuation allowance requires the Company to make estimates and judgments of future financial results. The Company has concluded that for purposes of quantifying valuation allowances, it would be appropriate to consider the reversal of taxable temporary differences related to indefinite-lived intangible assets when assessing the realizability of deferred tax assets that upon reversal, would give rise to operating losses that do not expire.

The Company evaluates all tax positions taken on its federal, state, and foreign tax filings to determine if the position is more likely than not to be sustained upon examination. For positions that meet the more likely than not to be sustained criteria, the largest amount of benefit to be realized upon ultimate settlement is determined on a cumulative probability basis. A previously recognized tax position is derecognized when it is subsequently determined that a tax position no longer meets the more likely than not threshold to be sustained. The evaluation of the sustainability of a tax position and the expected tax benefit is based on judgment, historical experience, and various other assumptions. Actual results could differ from those estimates upon subsequent resolution of identified matters. The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes.

Foreign currency translation

The assets and liabilities of our foreign subsidiaries are measured using the local currency as the functional currency and are translated into U.S. dollars at exchange rates as of the balance sheet date. Income statement amounts are translated at the weighted-average rates of exchange during the year. The translation adjustment is accumulated as a separate component of “Accumulated other comprehensive loss” within our Consolidated Balance Sheets. Foreign currency transaction gains and losses are included in “Other income or expense.” For the years ended December 31, 2019 and 2018, foreign currency transaction losses of approximately $202 and gains of $483, respectively, were included in “Other expense (income) - net” in the Consolidated Statements of Operations.

Research and development

The Company expenses research and development costs as costs are incurred. For the years ended December 31, 2019 and 2018, research and development expenses were $2,614 and $2,646, respectively, and were principally related to the Company’s friction management and railroad monitoring system products within the Rail Products and Services segment.

Reclassifications

Certain accounts in the prior year consolidated financial statements have been reclassified for comparative purposes principally to conform to the presentation in the current year period.

Recently issued accounting guidance

In August 2018, the FASB issued Accounting Standards Update (“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 is a service contract. The amendments in ASU 20118-15 are effective for fiscal years beginning after December 15, 2019 and for interim periods therein with early adoption permitted. The Company evaluated the potential impact of ASU 2018-15 on its consolidated financial position, results of operations, and cash flows and anticipates the adoption will have an immaterial effect on the Company’s Consolidated Financial Statements.

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. 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 will need to measure expected credit losses on assets that have a low risk of loss. The new standard will become effective for the Company January 1, 2020 and will be applied using the modified retrospective basis. The Company anticipates the adoption of this standard will not have a material impact on the Company’s Consolidated Financial Statements.

Recently adopted accounting guidance

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The new accounting requirements include the accounting for, presentation of, and classification of leases. The guidance resulted in most leases being capitalized as a right-of-use asset with a related balance sheet liability. The requirements of the new standard are effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. The Company adopted the provisions of ASU 2016-02 on January 1, 2019, using the modified retrospective approach as of the beginning of the period of adoption. Additionally, the Company has elected to apply the practical expedients for leases that commenced prior to the effective date, not to apply the recognition requirements in the standard to short-term leases, and not to separate non-lease components from lease components. The Company has presented the disclosures required by ASU 2016-02 in Note 8.

In February 2018, the FASB issued ASU 2018-02, “Income Statement – Reporting Comprehensive Income; Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”), which allows companies to reclassify stranded tax effects caused by the U.S. Tax Cuts and Jobs Act (the “Tax Act”) from accumulated other comprehensive income to retained earnings. The amendments eliminate the stranded tax effects resulting from the Tax Act and improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The Company adopted ASU 2018-02 during the first quarter of 2019 and has chosen to record the reclassification as of the beginning of the period of adoption. As a result of adopting this standard, we reclassified stranded tax effects of $633 from “Accumulated other comprehensive loss” to “Retained earnings.”

Revenue Recognition and Deferred Revenue [Abstract]

Deferred Revenue

Revenue

The Company’s revenues are comprised of product and service sales, including products and services provided under long-term agreements with its customers. All revenue is recognized when the Company satisfies its performance obligations under the contract, either implicit or explicit, by transferring the promised product or rendering a service to its customer either when or as its customer obtains control of the product or as the service is rendered. A performance obligation is a promise in a contract to transfer a distinct product or render a specific service to a customer. A contract’s transaction price is allocated to each distinct performance obligation. The majority of the Company’s contracts have a single performance obligation, as the promise to transfer products or render services is not separately identifiable from other promises in the contract and, therefore, not distinct. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or providing services. Revenue is recorded net of returns, allowances, customer discounts, and incentives. Sales, value added, and other taxes collected from customers and remitted to governmental authorities are accounted for on a net (excluded from revenues) basis. Shipping and handling costs are included in cost of goods sold.

The Company’s performance obligations under long-term agreements with its customers are generally satisfied as over time. Over time revenue is primarily comprised of transit infrastructure projects within Rail Products and Rail Technologies, long-term bridge projects within Piling and Fabricated Bridge Products, precast concrete buildings within Precast Concrete Products, and custom precision metering systems within Protective Coatings and Measurement Systems. Revenue from products or services provided to customers over time accounted for 28.5% and 26.0% of revenue for the years ended December 31, 2019 and 2018, 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 $136,014 and $121,919 for the years ended December 31, 2019 and 2018, 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 $50,761 and $41,334 for the years ended December 31, 2019 and 2018, respectively. As of December 31, 2019 and 2018, the Company had contract assets of $37,032 and $26,692, respectively, that were recorded in “Inventories - net” within the Consolidated Balance Sheets. As of December 31, 2019 and 2018, the Company had contract liabilities of $4,472 and $1,505, respectively, that were recorded in “Deferred revenue” within the Consolidated Balance Sheets.

Accounting for these long-term agreements involves the use of various techniques to estimate total revenues and costs. The Company estimates profit on these long-term agreements as the difference between total estimated revenues and expected costs to complete a contract and recognizes that profit over the life of the contract. Contract estimates are based on various assumptions to project the outcome of future events that may span several years. These assumptions include, among other things, labor productivity, cost and availability of materials, and timing of funding by customers. The nature of these long-term agreements may give rise to several types of variable consideration, such as claims, awards, and incentive fees. Historically, these amounts of variable consideration have not been considered significant. Contract estimates may include additional revenue for submitted contract modifications if there exists an enforceable right to the modification, the amount can be reasonably estimated, and its realization is probable. These estimates are based on historical collection experience, anticipated performance, and the Company’s best judgment at

that time. These amounts are generally included in the contract’s transaction price and are allocated over the remaining performance obligations. Changes in judgments related to the estimates above could impact the timing and amount of revenue recognized and, accordingly, the timing and amount of associated income. In the event that a contract loss becomes known, the entire amount of the estimated loss is recognized in the Consolidated Statements of Operations.

The majority of the Company’s revenue is from products transferred and services rendered to customers at a point in time, which is inherent in all major product and service categories. Point in time revenue accounted for 71.5% and 74.0% of revenue for the years ended December 31, 2019 and 2018, respectively. The Company recognizes revenue at the point in time in which the customer obtains control of the product or service, which is generally when 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 designated physical location.

The following table summarizes the Company’s net sales by major product and service category:

	December 31,
	2019		2018
Rail Products	$	194,464	$	188,590
Rail Technologies	127,344		130,934

Tubular and Energy Services	150,763		148,792
Total net sales	$	655,057	$	626,969

For the years ended December 31, 2019 and 2018, net sales by the timing of the transfer of goods and services are as follows:

Year ended December 31, 2019	Rail Products and Services		Construction Products		Tubular and Energy Services		Total
Point in time	$	240,047	$	115,590	$	112,645	$	468,282
Over time	81,761		66,896		38,118		186,775
Total net sales	$	321,808	$	182,486	$	150,763	$	655,057
Year ended December 31, 2018	Rail Products and Services		Construction Products		Tubular and Energy Services		Total
Point in time	$	232,814	$	106,168	$	124,734	$	463,716
Over time	86,710		52,485		24,058		163,253
Total net sales	$	319,524	$	158,653	$	148,792	$	626,969

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 Consolidated Balance Sheets.

Significant changes in contract assets during the year ended December 31, 2019 and 2018 included transfers to receivables from contract assets recognized at the beginning of the period of $24,487 and $18,941, respectively. Significant changes in contract liabilities during the year ended December 31, 2019 and 2018 included increases of $4,358 and $1,447, respectively, 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 year ended December 31, 2019 and 2018 of $1,462 and $1,141, respectively, that were included in the contract liabilities at the beginning of the respective period.

As of December 31, 2019, the Company had approximately $230,067 of remaining performance obligations, which is also referred to as backlog. Approximately 8.3% of the backlog as of December 31, 2019 was related to projects that are anticipated to extend beyond December 31, 2020.

Deferred RevenueDeferred revenue of $8,446 and $6,619 as of December 31, 2019 and 2018, respectively, consists of customer billings or payments received for which the revenue recognition criteria have not yet been met as well as contract liabilities (billings in excess of costs) on over time revenue projects. As of December 31, 2019 and 2018, contract liabilities, recorded within “Deferred revenue,” was $4,472 and $1,505, respectively. Advanced payments from customers typically relate to contracts with respect to which the Company has significantly fulfilled its obligations, but due to the Company’s continuing involvement with the project, revenue is not recognized until title, ownership, and risk of loss have passed to the customer.

Borrowings

On April 30, 2019, the Company, its domestic subsidiaries, and certain of its Canadian and European subsidiaries (collectively, the “Borrowers”), entered into the Third Amended and Restated Credit Agreement (“Amended 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. This Amended Credit Agreement modifies the prior revolving credit facility, which had a maximum credit line of $195,000 and extends the maturity date from March 13, 2020 to April 30, 2024. The Amended Credit Agreement provides for a five-year, revolving credit facility that permits aggregate borrowings of the Borrowers up to $140,000 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. The Amended 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 and provides for additional term loan borrowings of up to $25,000 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 Amended 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 their domestic subsidiaries, have been pledged to the lenders as collateral for the lending obligations.

Borrowings under the Amended Credit Agreement bear interest at rates based upon either the base rate or Euro-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 Amended 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 Amended Credit Agreement). The base rate and Euro-rate spreads range from 25 to 125 basis points and 125 to 225 basis points, respectively.

The Amended Credit Agreement includes three 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, as defined in the Amended Credit Agreement, and (ii) 3.50 to 1.00 for all testing periods 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, as defined in the Amended Credit Agreement, which must be a minimum of 1.25 to 1.00; and (c) Minimum Working Capital to Revolving Facility Usage Ratio, defined as the sum of the inventory and accounts receivable of the Borrowers and certain other Guarantors divided by the Revolving Facility Usage, as defined in the Amended Credit Agreement, which must be a minimum of 1.40 to 1.00.

As of December 31, 2019, the Company was in compliance with the covenants in the Amended Credit Agreement.

As of December 31, 2019 and 2018, the Company had outstanding letters of credit of approximately $492 and $425, respectively, and had net available borrowing capacity of $105,640 and $120,567, respectively.

United Kingdom

On April 29,2019, a subsidiary of the Company terminated a credit facility with NatWest Bank used for its United Kingdom operations. The facility had included an overdraft availability of £1,500 pounds sterling (approximately $1,924 as of December 31, 2018). There were no outstanding borrowings under this credit facility as of December 31, 2018, however, there were $318 in outstanding guarantees (as defined in the underlying agreement) as of December 31, 2018. The subsidiary had available borrowing capacity of $1,606 as of December 31, 2018.

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 is organized and operates in three different operating segments: the Rail Products and Services segment, the Construction Products segment, and the Tubular and Energy Services segment. The 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 makes 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 markets its products directly in all major industrial areas of the United States, Canada, and Europe, primarily through an internal sales force.

The Company’s Rail Products and Services segment provides a full line of new and used rail, trackwork, and accessories to railroads, mines, and other customers in the rail industry. The Rail Products and Services segment also designs and produces insulated rail joints, power rail, track fasteners, concrete railroad ties, coverboards, and special accessories for mass transit and other rail systems. In addition, the Rail Products and Services segment engineers, manufactures, and assembles friction management products and railway wayside data collection, application systems, railroad condition monitoring systems and equipment, wheel impact load detection, fire protection systems, and management systems.

The Company’s Construction Products segment sells and rents steel sheet piling, H-bearing pile, and other piling products for foundation and earth retention requirements. The Construction Products segment also sells bridge decking, bridge railing, structural steel fabrications, expansion joints, bridge forms, and other products for highway construction and repair. Lastly, the Construction Products segment produces precast concrete buildings and a variety of specialty precast concrete products.

The Company’s Tubular and Energy Services segment provides pipe coatings for natural gas pipelines and utilities, upstream test and inspection services, precision measurement systems for the oil and gas market, and produces threaded pipe products for the oil and gas markets as well as industrial water well and irrigation markets.

The following table illustrates net sales, profit, assets, depreciation/amortization, and expenditures for long-lived assets of the Company by segment. Segment profit from operations includes allocated corporate operating expenses. Operating expenses related to corporate headquarter functions that directly support the segment activity were 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.

Management believes the allocation of corporate operating expenses provides an accurate presentation of how the segments utilize corporate support activities. This provides the CODM a meaningful segment profitability reporting to support operating decisions and the allocation of resources.

The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies found in Note 1.

The operating results and assets of the Company’s operating segments were as follows as of and for the year ended December 31, 2019:

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingent Liabilities

Commitments and Contingent Liabilities

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 that is adjusted on a monthly basis as a percentage of cost of sales. This product warranty accrual is periodically adjusted 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, 2018	$	2,057
Additions to warranty liability	767
Warranty liability utilized	(1,602)
Balance as of December 31, 2019	$	1,222

During the year ended December 31, 2018, the Company incurred a charge of $611 within "Cost of goods sold" in our Rail Products and Services segment related to a commercial decision to support a customer concern related to a previous project.

On March 13, 2019, the Company and its subsidiary, CXT Incorporated entered into a Settlement Agreement (the “Settlement Agreement”) with Union Pacific Railroad (“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, beginning with a $2,000 immediate payment, and with the remaining $48,000 paid in installments over a six-year period commencing on March 13, 2019 through December 2024 pursuant to a Promissory Note. Additionally, commencing in January 2019 and through December 2024, UPRR has agreed to purchase 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 with 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 year ending December 31, 2020 and thereafter were as follows:

Year Ending December 31,
2020	$	8,000
2021	8,000
2022	8,000
2023	8,000
2024	8,000
Total	$	40,000

The Company reclassified $6,600 of the previously accrued warranty reserve related to the UPRR matter into its aggregate accrued settlement liability of $50,000 as of December 31, 2018. Therefore the Company recognized $43,400 in expense for the year ended December 31, 2018 for the remaining amount per the Settlement Agreement, which was recorded in “Concrete Tie Settlement expense” within our Consolidated Statements of Operations. As of December 31, 2019 and 2018, $8,000 and $10,000 was recorded within “Current portion of accrued settlement,” respectively, and $32,000 and $40,000 was recorded within “Long-term portion of accrued settlement,” respectively, within our Consolidated Balance Sheets.

Other Legal Matters

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 December 31, 2019.

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 December 31, 2019, no such disclosures were considered necessary.

Environmental Matters

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. 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.

The following table sets forth the Company’s undiscounted environmental obligation:

	Environmental Liability
Balance as of December 31, 2018	$	6,128
Additions to environmental obligations	54

Each quarter, management reviews operations and liquidity needs in each jurisdiction to assess the Company’s intent to reinvest foreign earnings outside of the United States. As of December 31, 2019, management determined that cash balances of its Canadian and United Kingdom subsidiaries exceeded projected capital needs by $7,800. Management does not intend for such amounts to be permanently reinvested outside of the United States and has therefore accrued foreign withholding taxes of $390 as of December 31, 2019. It is management’s intent and practice to indefinitely reinvest other undistributed earnings outside of the United States. Determination of the amount of any unrecognized deferred income tax liability associated with these undistributed earnings is not practicable because of the complexities of the hypothetical calculation.

A valuation allowance is required to be established or maintained when, based on currently available information and other factors, it is more likely than not that all or a portion of a deferred tax asset will not be realized. The Company has considered all available evidence, both positive and negative, in assessing the need for a valuation allowance in each jurisdiction.

During 2019, the Company reversed $29,648 of its valuation allowance previously recorded against U.S. deferred tax assets. The positive evidence considered in evaluating U.S. deferred tax assets included cumulative financial income over the three-year period ended December 31, 2019, as well as the composition and reversal patterns of existing taxable and deductible temporary differences between financial reporting and tax. Based on our evaluation, the Company believed it was appropriate to rely on forecasted future taxable income to support its U.S. deferred tax assets. The amount of deferred tax assets considered realizable, however, could be adjusted if negative evidence outweighs additional subjective evidence such as our projections for growth.

As of December 31, 2019 and 2018, the tax benefit of net operating loss carryforwards available for state income tax purposes was $901 and $1,253, respectively. The state net operating loss carryforwards will expire in various years through 2039. We believe it is more likely than not that a portion of the tax benefit from state operating loss carryforwards will not be realized. In recognition of this risk, we have provided a valuation allowance of $388 against deferred tax assets related to state operating loss carryforwards as of December 31, 2019.

As of December 31, 2019, the Company has foreign tax credit carryforwards in the amount of $34 that will expire in 2028 through 2029. We believe it is more likely than not that the tax benefit from foreign tax credit carryforwards will not be realized. In recognition of this risk, we have provided a valuation allowance of $34 against deferred tax assets related to foreign tax credit carryforwards at December 31, 2019.

As of December 31, 2019, the Company has net operating loss carryforwards in certain foreign jurisdictions of $2,019, which may be carried forward indefinitely. The foreign jurisdictions have incurred cumulative financial losses over the three-year period ended December 31, 2019 and have projected future taxable losses. We believe it is more likely than not that the tax benefit from these

loss carryforwards will not be realized. In recognition of this risk, we have provided a valuation allowance of $650, collectively, against deferred tax assets in foreign jurisdictions as of December 31, 2019.

The determination to record or not record a valuation allowance involves management judgment, based on the consideration of positive and negative evidence available at the time of the assessment. Management will continue to assess the realization of its deferred tax assets based upon future evidence, and may record adjustments to valuation allowances against deferred tax assets in future periods, as appropriate, that could materially impact net income.

The following table provides a reconciliation of unrecognized tax benefits as of December 31, 2019 and 2018:

	December 31,
	2019		2018
Unrecognized tax benefits at beginning of period:	$	481	$	599
Decreases based on tax positions for prior periods	(67)		(118)
Balance at end of period	$	414	$	481

The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $414 as of December 31, 2019. The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes. As of December 31, 2019 and 2018, the Company had accrued interest and penalties related to unrecognized tax benefits of $327 and $398, respectively. As of December 31, 2019, the Company did not expect any material increases or decreases to its unrecognized tax benefits within the next 12 months. Ultimate realization of these tax benefits is dependent upon the occurrence of certain events, including the completion of audits by tax authorities and expiration of statutes of limitations.

The Company files income tax returns in the United States and in various state, local, and foreign jurisdictions. The Company is subject to federal income tax examinations for the 2016 period and thereafter. With respect to the state, local, and foreign filings, certain entities of the Company are subject to income tax examinations for the 2015 period and thereafter.
