Item 1. | BUSINESS

General
Westinghouse Air Brake Technologies Corporation, doing business as Wabtec Corporation, is a Delaware corporation with headquarters at 30 Isabella Street in Pittsburgh, Pennsylvania. Our telephone number is 412-825-1000, and our website is located at www.wabteccorp.com. Except as the context otherwise requires, all references to “we”, “our”, “us”, the “Company” and “Wabtec” refer to Westinghouse Air Brake Technologies Corporation and its consolidated subsidiaries. George Westinghouse founded the original Westinghouse Air Brake Co. in 1869 when he invented the air brake. Westinghouse Air Brake Company (“WABCO”) was formed in 1990 when it acquired certain assets and operations from American Standard, Inc., now known as Trane (“Trane”). The Company went public on the New York Stock Exchange in 1995.
Throughout the years, the Company has made a number of strategic acquisitions leading the Company to where it is today. These have primarily included:
•the 1999 merger with MotivePower Industries, Inc. whereby the Company adopted its current name of Westinghouse Air Brake Technologies Corporation, or Wabtec;
•the 2017 acquisition of Faiveley Transport, S.A. (“Faiveley Transport”), a leading provider of value-added, integrated systems and services, primarily for the global transit rail market. Based in France, the Faiveley Transport business has roots to 1919 and made Wabtec a leader in manufacturing pantographs, automatic door mechanisms, air conditioning systems, railway braking systems and couplers; and
•the 2019 acquisition of GE Transportation, a business unit of General Electric Company. This brought a global technology leader and supplier of locomotives, equipment, services and digital solutions to the rail, mining, marine, stationary power and drilling industries into Wabtec.
As a result of those strategic acquisitions, as well as other smaller acquisitions and organic growth, Wabtec is now one of the world’s largest providers of locomotives, value-added, technology-based equipment, systems and services for the global freight rail and passenger transit industries with approximately 25,000 employees, excluding contingent workers, and operations in over 50 countries.

Industry Overview
The Company primarily serves the global freight rail and passenger transit industries. As such, our operating results are largely dependent on the level of activity, financial condition and capital spending plans of freight railroads and passenger transit agencies around the world, and transportation equipment manufacturers who serve those markets. Many factors influence these industries, including general economic conditions; traffic volumes, as measured by freight carloadings and passenger ridership; government spending on public transportation; and investment in new technologies. In general, trends such as increasing urbanization and growth in developing markets, a focus on sustainability and environmental awareness, increasing investment in technology solutions, an aging equipment fleet, and growth in global trade are expected to drive continued investment in freight rail and passenger transit.
The Association of the European Rail Industry, UNIFE, advocates for and represents European train builders and rail suppliers. UNIFE publishes a biennial market study that provides an overview of the market in its current form and a forecast of its future development in different regions and market segments. According to the 2020 biennial edition of the study, the accessible global market for railway products and services is more than $120 billion and is expected to grow in the medium- and long-term at an average annual growth rate of 2.3% through 2025, despite an 8% COVID-induced decline in 2020. The 2020 study also concluded that the rail sector had grown 3.6% annually since 2017, supporting the appeal of rail transport for all sectors from urban metro to commercial freight. The three largest geographic markets, which represented about 85% of the total accessible market, were Europe, North America and Asia Pacific, all of which are projected to continue to grow.
In Europe, only 19% of freight traffic is rail while the majority of the rail system serves the passenger transit market, which is expected to continue growing as energy and environmental policies encourage continued investment in public mass transit, and modal shift from car to rail, although this growth may be stunted in the near-term as a result of the COVID-19 pandemic. In North America, railroads carry about 40% of intercity freight, as measured by ton-miles, which is more than any other mode of transportation. North America’s rail network is regarded as the world’s most-efficient and lowest-cost freight rail service. There are more than 600 railroads operating in North America, with the largest railroads, referred to as “Class I”, accounting for more than 90% of the industry’s revenues. Growth in the Asia Pacific market has been driven mainly by the continued urbanization of China and India, and by continued investments in freight rail rolling stock and infrastructure in Australia to serve its mining and natural resources markets. India is making significant investments in rolling stock and infrastructure to modernize its rail system
According to UNIFE, most emerging markets, including Russia-CIS (Commonwealth of Independent States) and Africa-Middle East, are expected to grow at above-average rates as global trade leads to increased freight volumes and urbanization leads to increased demand for efficient mass-transportation systems. With about 1.3 million freight cars and about 21,000 locomotives, Russia-CIS is among the largest freight rail markets in the world. The COVID-19 pandemic has impacted the expected growth in these emerging markets.
As growth occurs, Wabtec expects to have additional opportunities to provide products and services in these markets. New technologies offered by Wabtec can provide solutions to improve safety, cost and reliability of rail, as well as support the modernization of the global rail fleets. In its study, UNIFE also said it expected increased investment in digitalization, automation, and predictive maintenance through artificial intelligence, all of which would improve efficiency in the global rail industry.

These principles are also rigorously applied to sustainability and safety.
Recent Acquisitions and Joint Ventures
See Note 3 of the Notes to Consolidated Financial Statements included in Part IV, Item 5 of this report for additional information about our recent acquisitions and joint ventures.
Backlog
The Company’s backlog was approximately $22 billion at December 31, 2021. For 2021, approximately 60% of total net sales came from aftermarket orders, which typically carry lead times of less than 30 days and are not included in backlog for a significant period of time.
The Company’s contracts are subject to standard industry cancellation provisions, including cancellations on short notice or upon completion of designated stages. Generally, if a customer were to cancel a contract we would have an enforceable right to payment for work completed up to the date of cancellation which would include a reasonable profit margin. Substantial scope-of-work adjustments are common. For these and other reasons, completion of the Company’s backlog may be delayed or canceled. The railroad industry, in general, has historically been subject to fluctuations due to overall economic conditions and the level of use of alternative modes of transportation.
The rollforward of the Company's backlog of firm customer orders and the expected year of completion are as follows:

In millions |  | Freight Segment |  | Transit Segment |  | Consolidated
Balance at December 31, 2020 |  | $ | 17,887 |  |  | $ | 3,704 |  |  | $ | 21,591 |
New orders |  | 5,964 |  |  | 2,763 |  |  | 8,727 |
Less: Net sales |  | (5,239) |  |  | (2,583) |  |  | (7,822) |
Adjustments / foreign exchange |  | (110) |  |  | (217) |  |  | (327) |
Balance at December 31, 2021 |  | $ | 18,502 |  |  | $ | 3,667 |  |  | $ | 22,169 |
Expected Delivery |  |  |  |  |  |
2022 |  | $ | 4,520 |  |  | $ | 1,748 |  |  | $ | 6,268 |
Other years |  | $ | 13,982 |  |  | $ | 1,919 |  |  | $ | 15,901 |

The Company saw no significant cancellations of backlog during the year ended December 31, 2021 despite the unprecedented pandemic caused by COVID-19 and its effects on locomotive parkings, carbuilds, and transit ridership levels. However, the economic slowdown and disruptions that were caused by COVID-19 did impact the timing of some orders in backlog as in certain cases the delivery of goods and services previously expected to be completed in the current year has been pushed out to future years.
Engineering and Development
To execute our strategy to develop new products, we invest in a variety of engineering and development activities. For the fiscal years ended December 31, 2021, 2020 and 2019, we invested $176 million, $162 million and $210 million, respectively, on product development and improvement activities.

Projects supported by green financing will largely target the objective of climate change mitigation by focusing on the efficiency of freight rail systems and public transport, as well as on the provision of energy-efficient customer solution services. Focus areas include:
• Clean transportation
• Eco-efficient and/or circular economy adapted products, production technologies and processes
• Renewable energy
• Pollution prevention and control
• Energy efficiency
Cybersecurity Framework
Cybersecurity and data protection are important considerations in the design and production of Wabtec products, projects, and services. Information technology is used and relied upon extensively by our business. We collect, process, and retain sensitive and confidential customer information, including proprietary business information, personal data and other information, some of which may be subject to privacy and security laws, regulations and/or customer-imposed data protection controls. To address risks related to cybersecurity and privacy, Wabtec seeks to leverage industry cybersecurity practices that have been developed by organizations such as National Institute of Standards and Technology (NIST) and the International Standardization Organization (ISO) and also engages external independent advisors. Wabtec’s Data Protection Plan describes the technical, physical and administrative controls used to protect the confidentiality, integrity, and availability of information provided to and managed by Wabtec. Cybersecurity is addressed and discussed regularly with our Chief Information Officer, the Audit Committee and Board of Directors. Wabtec also maintains SOC 1 Type 2 certification for select digital products, as well as cyber liability insurance coverage. We also regularly evaluate our response readiness, including disaster recovery plans and business continuity considerations in the case of a cyber incident. Finally, Wabtec engages in regular security awareness training to highlight and educate its employees on how to identify and mitigate cybersecurity risks at the individual level.

ESG Goals
Wabtec is committed to transparency on ESG topics, including the opportunities and challenges we encounter as we work to enhance performance and conduct business in a responsible manner. In 2020, we established ESG goals around innovation, operations, safety, and people. We report our progress on these goals annually in our published Sustainability Report, which can be found on our website at www.wabteccorp.com/sustainability. The content referred to on any website referred to in this annual report, including the Sustainability Report, is not incorporated by reference into this Form 10-K.
Wabtec developed an ESG governance framework to provide oversight for our climate action strategy. This structure starts with Wabtec's Board of Directors and its committees who oversee the execution of the Company’s ESG strategy as part of their oversight of Wabtec’s overall business. In particular, the Nominating and Corporate Governance Committee assists the Board in its oversight of Wabtec’s sustainability strategy and execution against key goals, as well as the review of climate-related risks and opportunities. To further facilitate the Board’s engagement and oversight, climate was added as a risk category in Wabtec’s enterprise risk management process.
Employees
Human Capital
At Wabtec, we believe performance drives progress, and are committed to developing sustainable transportation solutions that move and improve the world. We are committed to driving an inclusive culture and integrating our talent and capabilities across the enterprise. As a company, we believe that protecting the health and safety of our people and the environment is the responsibility of everyone at Wabtec, especially during a global pandemic.
Our headquarters are in Pittsburgh, Pennsylvania and we have offices and facilities in over 50 countries around the globe. As of December 31, 2021, we have a global workforce of approximately 25,000 employees, excluding contingent workers.
Diversity and Inclusion
Wabtec is committed to ensuring a diverse and inclusive workplace that respects and seeks the unique talents, experiences and viewpoints of all our employees. Wabtec has a Diversity and Inclusion Council, led by members of Wabtec’s executive leadership team, who oversee global diversity and inclusion policies and initiatives. We strive to create an inclusive workplace where employees can be themselves. Our Board of Directors also plays a critical role in creating an organization that prioritizes, supports, and invests in diversity, inclusion, and equity. Over the last two years, Wabtec has named three diverse
members to its Board. Currently, 40% of Wabtec’s Board is diverse (gender; race/ethnicity), and over 18% of Wabtec’s global senior management are female and roughly 18% are people of color based in the U.S. In 2020, women constituted approximately 16% of our global workforce and approximately 18% of our salaried employees and people of color constituted approximately 20% of our U.S. salaried workforce and approximately 24% of the total U.S. workforce.
Training and Development
We continually invest in our employees’ career growth and provide employees with a wide range of development opportunities, including face-to-face, virtual, social and self-directed learning, mentoring and coaching programs. We have invested in training courses through Wabtec’s Learning Management System (LMS). In 2021, Wabtec partnered with a third-party to provide diversity and inclusion training. Over 4,000 employees participated in the training, which was coupled with tools and resources for people leaders to help make diversity and inclusion part of a long-term conversation rather than a one-time training.
Our two-year Leadership, Expertise, Advancement and Development (LEAD) program is the primary path for university graduates into Wabtec. LEAD is a two-year program that offers an immersive learning experience in the fields of engineering, operations, finance and IT along with extensive leadership training designed to build the next generation of leaders. On average, there are 100 participants in the LEAD program that rotate between business units every six months to work on strategic projects and assignments, gain exposure to senior leadership and build their global professional network. We are focused on strengthening this program to support our global talent pipeline.
Health and Safety
When it comes to employee safety, our commitment is to provide safe work environments for our employees and to meet or exceed environmental, health, and safety (EHS) laws and regulations in the places where we operate. In 2020, the Company relaunched the Environment, Health, and Safety component of the Wabtec Management System (known as the “EHS WMS”) to strengthen our management system approach to addressing EHS risks and promote the consistent implementation of best practices across all our global manufacturing and services sites, regardless of how local laws are implemented or enforced. The EHS WMS establishes standard expectations in 13 core competency areas, including leadership and accountability, regulatory applicability review, EHS processes and systems, risk assessment, safety defenses, exposure defenses, environmental defenses
12

and contractor management. Operational sites are measured against these EHS program expectations. In addition, the Company’s EHS WMS is directly aligned to accepted international standards, such as ISO 14001 for Environmental and ISO 45001 for Occupational Health and Safety. With zero fatalities and over 80 operational sites with zero recordable injuries, 2020 marked the 13th consecutive year of injury rate reductions across Wabtec's vast operations.
In 2021, Wabtec continued its commitment to safety and launched a four week EHS leadership training course aimed at building the toolkits of front-line supervisors and plant managers. The course was designed to establish a common understanding of Wabtec’s EHS tools and terminology, initiate a partnership between the plant manager and their EHS leader on a personal action plan, connect plant managers to the broader network of global leaders, and encourage decision making at the site level that is informed by an understanding of EHS impacts and of legal and compliance responsibilities. In 2021, over 120 leaders from 26 countries attended the training.
COVID-19
The pandemic has reinforced the importance of keeping Wabtec employees safe and healthy while keeping essential rail services and the global economy moving. When the pandemic began, Wabtec launched its COVID-19 Crisis Management Team, which met daily to focus on three key elements: protecting our people, serving our customers, and ensuring business continuity. Manufacturing and office locations were required to implement risk assessment methodologies and rethink work practices to allow for remote working or social distancing, develop new procedures for workplace entry, strengthen site-level crisis management teams and implement new tools for rapid communication with site employees. Site leaders and people managers were trained on techniques for communicating transparently and navigating complex business decisions during a crisis.
Compensation and Benefits
We remain committed to a strong pay-for performance philosophy that aligns individual performance, behaviors and business results with individual rewards. To deliver on that commitment, we utilize market data to benchmark to the external market, and consider factors such as an employee’s role and experience, the location of the job and performance when determining compensation.
We provide our employees resources to help them succeed. We offer a wide range of benefits including healthcare and wellness benefits, retirement benefits, an Employee Assistance Program, Employee Resource Groups to build diverse communities at Wabtec, and paid time off.
Regulation
In the course of our operations, we are subject to various regulations and standards of governments and other agencies in the U.S. and around the world. These entities typically govern equipment, safety and interoperability standards for freight rail rolling stock and passenger transit, oversee a wide variety of rules and regulations governing safety and design of equipment, and evaluate certification and qualification requirements for suppliers. New products generally must undergo testing and approval processes that are rigorous and lengthy. As a result of these regulations and requirements, we must usually obtain and maintain certifications in a variety of jurisdictions and countries. The governing bodies include the FRA and the Association of American Railroads ("AAR") in the U.S., and the International Union of Railways (“UIC”) and the European Railway Agencies in Europe. Also, in Europe, the European Committees for Standardization continually draft new European standards which cover, for example, the Reliability, Availability, Maintainability and Safety of railways systems. To guarantee interoperability in Europe, the European Union for Railway Agencies is responsible for defining and implementing Technical Standards of Interoperability, which covers areas such as infrastructure, energy, rolling stock, telematic applications, traffic operation and management subsystems, noise pollution and waste generation, protection against fire and smoke, and system safety.
Most countries and regions in which Wabtec does business have similar rule-making bodies. For example, in Russia, a GOST-R certificate of conformity is mandatory for all products related to the safety of individuals in Russian territory. In China, any product or system sold on the Chinese market must have been certified in accordance with national standards. In the local Indian market, most products are covered by regulations patterned after AAR and UIC standards.
Effects of Seasonality
Our business has limited seasonality. Third quarter results may be affected by the timing of services performed under our locomotive maintenance contracts and vacation and scheduled plant shutdowns at several of our major customers. Fourth quarter results may be affected by the timing of spare parts and service orders placed by transit agencies worldwide. Quarterly results can also be affected by the timing of projects in backlog and by project delays.
Environmental Matters
The Company is subject to a variety of environmental laws and regulations governing discharges to air and water, the handling, storage and disposal of hazardous or solid waste materials and the remediation of contamination associated with
13

releases of hazardous substances. The Company believes its operations currently comply in all material respects with all of the various environmental laws and regulations applicable to our business; however, there can be no assurance that environmental requirements will not change in the future or that we will not incur significant costs to comply with such requirements.

Item 1A. | RISK FACTORS

RISKS RELATED TO OUR BUSINESS AND OPERATIONS
We are dependent upon key customers.
We rely on several key customers who represent a significant portion of our business. While we believe our relationships with our customers are generally good, our top customers could choose to reduce or terminate their relationships with Wabtec. In addition, many of our customers place orders for products on an as-needed basis and operate in cyclical industries. As a result, customer order levels have varied from period to period in the past and may vary significantly in the future. Such customer orders are dependent upon their markets and customers and may be subject to delays and cancellations. Furthermore, the average service life of certain products in our end markets has increased in recent years due to innovations in technologies and manufacturing processes, which has also allowed end users to replace parts less often. As a result of our dependence on our key customers, we could experience a material adverse effect on our business, results of operations and financial condition if we lost any one or more of our key customers or if there is a reduction in their demand for our products.
Our business operates in a highly competitive industry.
We operate in a global, competitive marketplace and face substantial competition from a limited number of established competitors, some of which may have greater financial resources than we do, may have a more extensive low-cost sourcing strategy and presence in low-cost regions than we do or may receive significant governmental support. Price competition is strong and, coupled with the existence of a number of cost conscious customers with significant negotiating power, has historically limited our ability to increase prices. In addition to price, competition is based on product performance and technological leadership, quality, reliability of delivery and customer service and support. If our competitors invest heavily in innovation and develop products that are more efficient or effective than our products, we may not be able to compete effectively. There can be no assurance that competition in one or more of our markets will not adversely affect us and our results of operations.
16

A failure to predict and react to customer demand could adversely affect our business.
If we are unable to accurately forecast demand for our existing products or to react appropriately to changes in demand, we may experience delayed product shipments and customer dissatisfaction. If demand increases significantly from current levels, both we and our suppliers may have difficulty meeting such demand, particularly if such demand increases occur rapidly. Alternatively, we may carry excess inventory if demand for our products decreases below projected levels.
Additionally, we have dedicated significant resources to the development, manufacturing and marketing of new products. Decisions to develop and market new transportation products are typically made without firm indications of customer acceptance. Moreover, by their nature, new products may require alteration of existing business methods or threaten to displace existing equipment in which our customers may have a substantial capital investment. There can be no assurance that any new products that we develop will gain widespread acceptance in the marketplace or that such products will be able to compete successfully with other new products or services that may be introduced by competitors. Furthermore, we may incur additional warranty or other costs as new products are tested and used by customers.
Failure to accurately predict and react to customer demand could have a material adverse effect on our business, results of operations and financial condition.
We may fail to respond adequately or in a timely manner to innovative changes in new technology.
In recent years, the global transportation landscape has been characterized by rapid changes in technology, leading to innovative transportation and logistics concepts that could change the way the railway industry does business. There may be additional innovations impacting the railway industry that we cannot yet foresee. Any failure by us to quickly adapt to and adopt new innovations in products and processes desired by our customers may result in a significant loss of demand for our product and service offerings. In addition, advances in technology may require us to increase investments in order to remain competitive, and our customers may not be willing to accept higher prices to cover the cost of these investments.
Our revenues are subject to cyclical variations in the railway and passenger transit markets and changes in government spending.
The railway industry historically has been subject to significant fluctuations due to overall economic conditions, the use of alternate methods of transportation and the levels of government spending on railway projects. In economic downturns, railroads have deferred, and may defer, certain expenditures in order to conserve cash in the short term. For example, the economic slowdown that was caused by COVID-19 impacted the timing of some orders, as customers deferred the delivery of some goods and services to future years. Reductions in freight traffic may reduce demand for our replacement products.
The passenger transit railroad industry is also cyclical and is influenced by a variety of factors. New passenger transit car orders vary from year to year and are influenced by a variety of factors, including major replacement programs, the construction or expansion of transit systems by transit authorities and the quality and cost of alternative modes of transportation. To the extent that future funding for proposed public projects is curtailed or withdrawn altogether as a result of changes in political, economic, fiscal or other conditions beyond our control, such projects may be delayed or canceled, resulting in a potential loss of business for us, including transit aftermarket and new transit car orders. There can be no assurance that economic conditions will be favorable or that there will not be significant fluctuations adversely affecting the industry as a whole and Wabtec.
Our backlog is not necessarily indicative of the level of our future revenues.
Our backlog represents future production and estimated potential revenue attributable to firm contracts with, or written orders from, our customers for delivery in various periods. Instability in the global economy, negative conditions in the global credit markets, volatility in the industries that our products serve, changes in legislative policy, adverse changes in the financial condition of our customers, adverse changes in the availability of raw materials and supplies, or un-remedied contract breaches could possibly lead to contract termination or cancellations of orders in our backlog or request for deferred deliveries of our backlog orders, each of which could adversely affect our cash flows and results of operations. For example, although the Company saw no material cancellations of backlog during the year ended December 31, 2021, the economic slowdown that was caused by COVID-19 did impact the timing of some orders in backlog as the delivery of goods and services previously expected to be completed in the current year were pushed out to subsequent periods.
Equipment failures, interruptions, delays in deliveries or extensive damage to our facilities, supply chains, distribution systems or information technology systems, could adversely affect our business.
All of our facilities, equipment, supply chains, distribution systems and information technology systems are subject to the risk of catastrophic loss due to unanticipated events, such as cyber attacks, disease outbreak, fires, earthquakes, explosions, floods, tornadoes, hurricanes or weather conditions. An interruption in our manufacturing capabilities, supply chains, distribution systems or information technology systems, whether as a result of such catastrophic loss or any other reason, could reduce, prevent or delay our production and shipment of our product offerings, result in defective products or services, damage customer relationships and our reputation and result in legal exposure and large repair or replacement expenses. This could result in the delay or termination of orders, the loss of future sales and a negative impact to our reputation with our customers.
17

Third-party insurance coverage that we maintain with respect to such matters will vary from time to time in both type and amount depending on cost, availability and our decisions regarding risk retention, and may be unavailable or insufficient to protect us against losses. Any of these risks coming to fruition could materially adversely affect our business, results of operations and financial condition.
Disruption of our supply chain could have an adverse impact on our business, financial condition, and results of operations.
Our ability to make, move, and sell our products is critical to our success. Damage or disruption to our supply chain, including third-party manufacturing or transportation and distribution capabilities, could impair our ability to manufacture or sell our products. Failure to take adequate steps to mitigate the likelihood or potential impact of disruptions, or to effectively manage such events if they occur, particularly when a product is sourced from a single supplier or location, could adversely affect our business or financial results. Due to the ongoing impacts and uncertainty of continued impacts of the COVID-19 pandemic and the global government actions to contain it, some of our supply chains, particularly in China, India, the U.S., and Europe, have been, and continue to be, impacted. Supply chain disruptions and labor availability have caused component and chip shortages resulting in an adverse effect on the timing of the Company’s revenue generation. Additionally, broad-based inflation, escalation of metals and commodities costs, transportation and logistics costs and labor costs have all resulted from the COVID-19 pandemic. There can be no assurance that there will not be further, or deeper, supply chain disruptions, or that the steps we are taking to mitigate such disruptions will be effective or achieve their desired results in a timely fashion.
In addition, disputes with significant suppliers, including disputes regarding pricing or performance, could adversely affect our ability to supply products to our customers and could materially and adversely affect our product sales, financial condition, and results of operations.
We intend to pursue acquisitions, joint ventures and alliances that involve a number of inherent risks, any of which may cause us not to realize anticipated benefits.
One aspect of our business strategy is to selectively pursue acquisitions, joint ventures and alliances that we believe will improve our market position and provide opportunities to realize operating synergies. These transactions involve inherent risks and uncertainties, any one of which could have a material adverse effect on our business, results of operations and financial condition including:
•difficulties in achieving identified financial and operating synergies, including the integration of operations, services and products;
•diversion of management’s attention from other business concerns;
•the assumption of unknown liabilities; and
•unanticipated changes in the market conditions, business and economic factors affecting such an acquisition, joint venture or alliance.
We cannot assure that we will be able to consummate any future acquisitions, joint ventures or other business combinations. If we are unable to identify or consummate suitable acquisitions, joint ventures or alliances, we may be unable to fully implement our business strategy, and our business and results of operations may be adversely affected as a result. In addition, our ability to engage in such strategic transactions will be dependent on our ability to raise substantial capital, and we may not be able to raise the funds necessary to implement this strategy on terms satisfactory to us, if at all.
The integration of our recently completed acquisitions may not result in anticipated improvements in market position or the realization of anticipated operating synergies or may take longer to realize than expected.
Although we believe that our recent acquisitions will improve our market position and realize positive operating results, including operating synergies, operating expense reductions and overhead cost savings, we cannot be assured that these improvements will be obtained or the timing of such improvements. The management and acquisition of businesses involves substantial risks, any of which may result in a material adverse effect on our business and results of operations, including:
•the uncertainty that an acquired business will achieve anticipated operating results;
•significant expenses to integrate;
•diversion of management’s attention from business operations to integration matters;
•departure of key personnel from the acquired business;
•effectively managing entrepreneurial spirit and decision-making;
•integration of different information systems;
•unanticipated costs and exposure to unforeseen liabilities; and
18

•impairment of assets.
The effects of COVID-19 and other potential future public health crises, epidemics, pandemics or similar events on our business, operating results and cash flows are uncertain.
We face a wide variety of risks related to health epidemics, pandemics and similar outbreaks, including the global outbreak of COVID-19. Since first reported in late 2019, the COVID-19 pandemic has dramatically impacted the global health and economic environment, including millions of confirmed cases, business slowdowns or shutdowns, government challenges and market volatility of an unprecedented nature. Although we have, to date, managed to continue most of our operations, we cannot predict the future course of events nor can we assure that this global pandemic, including its economic impact, will not have a material adverse impact on our business, financial position, results of operations and/or cash flows. The extent of the impact of the COVID-19 pandemic on our operational and financial performance remains uncertain and will depend on future pandemic related developments, including the duration of the pandemic, any potential subsequent waves of COVID-19 and new strains of the virus, the effectiveness, distribution and acceptance of COVID-19 vaccines, and related government actions to prevent and manage disease spread, all of which are uncertain and cannot be predicted. Our operations may be further impacted by the COVID-19 pandemic if significant portions of our workforce are unable to work effectively, including because of illness, quarantines, travel restrictions or absenteeism; steps the company has taken to protect health and well-being; government actions; facility closures; work slowdowns or stoppages; inadequate supplies or resources (such as reliable personal protective equipment, testing and vaccines); or other circumstances related to COVID-19. Governments around the world have taken steps to mitigate some of the more severe anticipated economic effects, but there can be no assurance that such steps will be effective or achieve their desired results in a timely fashion.
The COVID-19 pandemic has resulted in operational and supply chain disruptions for us and our customers and may further adversely affect operations and the operations of our customers and suppliers. Accordingly, COVID-19 had a materially adverse impact on our operations and business results for the years ended December 31, 2021, and 2020. Supply chain disruptions and shortages in labor availability have caused component and chip shortages, which have resulted in adverse effects on the timing of our revenue generation. Additionally, broad-based inflation, escalation of metals and commodities costs, transportation and logistics costs and labor costs have all resulted from the COVID-19 pandemic and have adversely impacted our business. W e expect COVID-19 to continue to have a materially adverse impact on our operations and business results into 2022. The spread of COVID-19, and the emergence of new strains of the virus, have caused us to modify our business practices and to implement significant proactive measures to protect the health and safety of employees, and we may take further actions as may be required by government authorities or as we determine are appropriate under the circumstances. There is no certainty that such measures will be sufficient to mitigate the continued risks posed by the pandemic.
The COVID-19 pandemic and related volatility in financial markets and deterioration of national and global economic conditions could affect our business and operations in a variety of ways. For example, we have experienced and could experience further operational disruptions and financial losses as a result of the following:
•a decrease in demand for our products as a result of COVID-19 and cost control measures implemented by our customers;
•delays in orders or delivery of orders, the occurrence of which negatively impacts our cash conversion cycle and ability to convert our backlog into cash;
•inability to collect full or partial payments from customers due to deterioration in customer liquidity, including customer bankruptcies;
•a shutdown of one or multiple of our manufacturing facilities due to government restrictions or illness in connection with COVID-19.
The continued spread of COVID-19 has also led to disruption and volatility in the global capital markets, which depending on future developments may make it more costly or difficult for us to obtain debt or equity financing, including to refinance our existing debt, or to identify or execute on investment opportunities, in each case on terms and within time periods acceptable to us. We are also monitoring the impacts of COVID-19 on the fair value of our assets. While we do not currently anticipate any material impairments on our assets as a result of COVID-19, future changes in expectations for sales, earnings and cash flows related to intangible assets and goodwill below our current projections could cause these assets to be impaired.
We continue to work with our stakeholders (including customers, employees, suppliers and local communities) in an effort to address responsibly this global pandemic. We continue to monitor the situation, to assess further possible implications to our employees, business, supply chain and customers, and to take certain actions in an effort to mitigate various adverse consequences. However, uncertainty around general global economic and market conditions, exacerbated by the COVID-19 pandemic, will have an impact on our sales and operations in 2022 and beyond.
19

We expect that the longer the COVID-19 pandemic, including its economic disruption, continues, the greater the adverse impact on our business operations, financial performance and results of operations could be. Given the tremendous uncertainties and variables, we cannot at this time predict the impact of the global COVID-19 pandemic, or any future pandemic, but any one could have a material adverse impact on our business, financial position, results of operations and/or cash flows.
RISKS RELATED TO INTERNATIONAL OPERATIONS
A growing portion of our sales may be derived from our international operations, which exposes us to certain risks inherent in doing business on an international level.
For the fiscal year ended December 31, 2021, approximately 60% of our consolidated net sales were to customers outside of the United States. We intend to continue to expand our international operations, including in emerging markets, in the future. Our global headquarters for the Transit group is located in France, and we conduct other international operations through a variety of wholly and majority-owned subsidiaries and joint ventures, including in Australia, Austria, Brazil, Canada, China, Czech Republic, France, Germany, India, Italy, Kazakhstan, Macedonia, Mexico, the Netherlands, Poland, Russia, Spain, South Africa, Turkey, and the United Kingdom. As a result, we are subject to various risks, any one of which could have a material adverse effect on those operations and on our business as a whole, including:
•lack of complete operating control;
•lack of local business experience;
•currency exchange fluctuations and devaluations;
•restrictions on currency conversion or the transfer of funds or limitations on our ability to repatriate income or capital;
•the complexities of operating within multiple tax jurisdictions;
•foreign trade restrictions and exchange controls;
•adverse impacts of international trade policies, such as import quotas, capital controls or tariffs;
•difficulty enforcing agreements and intellectual property rights;
•the challenges of complying with complex and changing laws, regulations, and policies of foreign governments;
•the difficulties involved in staffing and managing widespread operations;
•the potential for nationalization of enterprises;
•economic, political and social instability;
•possible local catastrophes, such as natural disasters and epidemics; and
•possible terrorist attacks, conflicts and wars, including those against American interests.
Our exposure to the risks associated with international operations may intensify if our international operations expand in the future.
We may incur increased costs due to fluctuations in interest rates and foreign currency exchange rates
In the ordinary course of business, we are exposed to increases in interest rates that may adversely affect funding costs associated with variable-rate debt and changes in foreign currency exchange rates. We are subject to currency exchange rate risk to the extent that our costs may be denominated in currencies other than those in which we earn and report revenues and vice versa. In addition, a decrease in the value of any of these currencies relative to the U.S. dollar could reduce our profits from non-U.S. operations and the translated value of the net assets of our non-U.S. operations when reported in U.S. dollars in our consolidated financial statements. We may seek to minimize these risks through the use of interest rate swap contracts and currency hedging agreements. There can be no assurance that any of these measures will be effective. Material changes in interest or exchange rates could result in material losses to us.
We have substantial operations located in emerging markets, and are subject to regulatory, economic, social and political uncertainties in such markets.
We have substantial operations located in emerging markets, such as Brazil, India, Kazakhstan, the Russian Federation and Ukraine. Operations in such emerging markets are inherently risky due to a number of regulatory, economic, social and political uncertainties. These risks include economies that may be dependent on only a few products and are therefore subject to significant fluctuations, weak legal systems which may affect our ability to enforce contractual rights, possible exchange controls, unstable governments, nationalization or privatization actions or other government actions affecting the flow of goods and currency.
20

Significant changes in economic and regulatory policy in emerging countries as well as social or political uncertainties could significantly harm business and economic conditions in these markets generally and could disproportionately impact the rail industry, which could adversely affect our business and prospects in these markets.
In addition, physical and financial infrastructure may be less developed in some emerging countries than that of many developed nations. Any disruptions with respect to banking and financial infrastructure, communication systems or any public facility, including transportation infrastructure, could disrupt our normal business activity. Such disruptions could interrupt our business operations and significantly harm our results of operations, financial condition and cash flows.
RISKS RELATED TO MACRO-ECONOMIC CONDITIONS AND POLICIES
Prolonged unfavorable economic and market conditions could adversely affect our business.
Unfavorable general economic and market conditions in the United States and internationally, particularly in our key end markets, could have a negative impact on our sales and operations. To the extent that these factors result in continued instability of capital markets, shortages of raw materials or component parts, longer sales cycles, deferral or delay of customer orders or an inability to market our products effectively, our business and results of operations could be materially adversely affected.
We may be exposed to raw material shortages, supply shortages and fluctuations in raw material, energy and commodity prices.
We purchase energy, steel, aluminum, copper, rubber and rubber-based materials, chemicals, polymers and other key manufacturing inputs from outside sources, and traditionally have not had long-term pricing contracts with our pure raw material suppliers. The costs of these raw materials have been volatile historically and are influenced by factors that are outside our control. If we are unable to pass increases in the costs of our raw materials on to our customers, experience a lag in our ability to pass increases to our customers, or operational efficiencies are not achieved, our operating margins and results of operations may be materially adversely affected.
Our businesses compete globally for key production inputs. In addition, we rely upon third-party suppliers, including certain single-sourced suppliers, for various components for our products. In the event of a shortage or discontinuation of certain raw materials or key inputs, we may experience challenges sourcing certain of our components to meet our production requirements and may not be able to arrange for alternative sources of certain raw materials or key inputs. Any such shortage may materially adversely affect our competitive position versus companies that are able to better or more cheaply source such raw materials or key inputs.
Changes to international trade policies, including tariffs and foreign trade restrictions, could adversely affect our business.
As a global transportation company, we generate export sales from our U.S. operations and also derive international sales through our foreign subsidiaries, licensees and joint ventures. We also do business with industry suppliers located in various international markets. A protectionist trade environment in either the United States or those foreign countries in which we do business, such as a change in the current tariff structures, export compliance or other trade policies, may adversely affect our business. In particular, such policies may impact or delay our customers' investments in our products, reduce the competitiveness of our products in certain markets, and inhibit our ability to cost-effectively purchase necessary inputs from certain suppliers. In addition, to the extent developments in international trade relations result in reduced global trade or slower growth in global trade, it is likely that this would result in reductions in investment in freight and transit rail.
International trade policies are affected by a diverse array of factors, including global and national economic and political conditions, which make it impossible for us to predict future developments regarding tariffs and other trade restrictions. Although we actively monitor developments in international trade and proactively engage in efforts to mitigate the effect of trade policies, there can be no guarantee that these efforts will be successful.
LEGAL AND REGULATORY RISKS
We are subject to a variety of laws and regulations, including anti-corruption laws, in various jurisdictions.
We are subject to various laws, rules and regulations administered by authorities in jurisdictions in which we do business, such as the anti-corruption laws of the U.S. Foreign Corrupt Practices Act, the French Law n° 2016-1691 (Sapin II) and the U.K. Bribery Act, relating to our business and our employees. We are also subject to other laws and regulations governing our international operations, including regulations administered by the U.S. Department of Commerce’s Bureau of Industry and Security, the U.S. Department of Treasury’s Office of Foreign Assets Control, and various non-U.S. government entities, including applicable export control regulations, economic sanctions on countries and persons, customs requirements, currency exchange regulations, and transfer pricing regulations. Despite our policies, procedures and compliance programs, our internal controls and compliance systems may not be able to protect us from prohibited acts willfully committed by our employees, agents or business partners that would violate such applicable laws and regulations. Any such improper acts could
21

damage our reputation, subject us to civil or criminal judgments, fines or penalties, and could otherwise disrupt our business, and as a result, could materially adversely impact our business, results of operations and financial condition.
In addition, our manufacturing operations are subject to safety, operations, maintenance and mechanical standards, rules and regulations enforced by various federal and state agencies and industry organizations both domestically and internationally. Our business may be adversely impacted by new rules and regulations or changes to existing rules or regulations, which could require additional maintenance or substantial modification or refurbishment of certain of our products or could make such products obsolete or require them to be phased out prior to their useful lives. We are unable to predict what impact these or other regulatory changes may have, if any, on our business or the industry as a whole. We cannot assure that costs incurred to comply with any new standards or regulations will not be material to our business, results of operations and financial condition.
We are subject to a variety of environmental laws and regulations.
We are subject to a variety of increasingly stringent environmental laws and regulations governing discharges to air and water, substances in products, the handling, storage and disposal of hazardous or solid waste materials and the remediation of contamination associated with releases of hazardous substances. We have incurred, and will continue to incur, both operating and capital costs to comply with environmental laws and regulations, including costs associated with the clean-up and investigation of some of our current and former properties and offsite disposal locations. We believe our operations currently comply in all material respects with all of the various environmental laws and regulations applicable to our business; however, there can be no assurance that environmental requirements will not change in the future or that we will not incur significant costs to comply with such requirements. Failure to comply with environmental laws and regulations could have significant consequences on our business and results of operations, including the imposition of substantial fines and sanctions for violations, injunctive relief (including requirements that we limit or cease operations at affected facilities), and reputational risk.
In addition, certain of our products are subject to extensive, and increasingly stringent, statutory and regulatory requirements governing, e.g., emissions and noise, including standards imposed by the U.S. Environmental Protection Agency, the European Union and other regulatory agencies around the world. We have made, and will continue to make, significant capital and research expenditures relating to compliance with these standards. The successful development and introduction of new and enhanced products in order to comply with new regulatory requirements are subject to other risks, such as delays in product development, cost over-runs and unanticipated technical and manufacturing difficulties. In addition to these risks, the nature and timing of government implementation and enforcement of these standards-particularly in emerging markets-are unpredictable and subject to change.
Future climate change regulation could result in increased operating costs, affect the demand for our products or affect the ability of our critical suppliers to meet our needs.
Management believes it is reasonably likely that the scientific and political attention to issues concerning the existence and extent of climate change, and the role of human activity in it, will continue, with the potential for further regulation that affects the company’s operations. The potential challenges posed by evolving climate change policy and prospective legislation are heavily dependent on the nature and degree of climate change legislation and the extent to which it applies to our industry. Although uncertain, these developments could increase costs or reduce the demand for the products the company sells. The company’s production and processing operations typically result in emissions of greenhouse gases. Likewise, emissions arise from midstream and downstream operations, including operations of our locomotives and other products. Finally, although beyond the control of the company, the use of fuels and related products by operators also results in greenhouse gas emissions that may be regulated. International agreements, domestic legislation and regulatory measures to limit greenhouse gas emissions are currently in various phases of discussion or implementation. While we are carefully monitoring developments and reviewing the challenges associated with alternative proposals, at this time, we cannot predict the ultimate impact of climate change and climate change legislation on our operations. Further, when or if these impacts may occur cannot be assessed until legislative policy is more developed and specific legislative proposals begin to take shape. Any laws or regulations that may be adopted to restrict or reduce emissions of greenhouse gas could require us to incur increased operating costs and could have an adverse effect on demand for our products. In addition, the price and availability of certain of the raw materials that we use could vary in the future as a result of environmental laws and regulations affecting our suppliers. An increase in the price of our raw materials or a decline in their availability could adversely affect our operating margins or result in reduced demand for our products.
The occurrence of litigation in which we are, or could be, named as a defendant is unpredictable.
From time to time, we are subject, directly or through our subsidiaries, to litigation or other commercial disputes and other legal and regulatory proceedings with respect to our business, customers, suppliers, creditors, stockholders, product liability (including, asbestos claims), intellectual property infringement, competition and antitrust claims, warranty claims or environmental-related matters.
22

Due to the inherent uncertainties of any litigation, commercial disputes or other legal or regulatory proceedings, we cannot accurately predict their ultimate outcome, including the outcome of any related appeals. We may incur significant expense to defend or otherwise address current or future claims. Although we maintain insurance policies for certain risks, we cannot make assurances that this insurance will be adequate to protect us from all material judgments and expenses related to potential future claims or that these levels of insurance will be available in the future at economical prices or at all. In addition, although in some cases we may be indemnified by non-affiliated entities that retain liabilities in connection with specific matters, there can be no assurance that these indemnitors will remain financially viable and capable of satisfying their obligations.
Any litigation, even a claim without merit, could result in substantial costs and diversion of resources and could have a material adverse effect on our business and results of operations.
Our manufacturer’s warranties or product liability may expose us to potentially significant claims.
We warrant the workmanship and materials of many of our products. Accordingly, we are subject to a risk of product liability or warranty claims in the event that the failure of any of our products results in personal injury or death or does not conform to our customers’ specifications. In addition, in recent years, we have introduced a number of new products for which we do not have a history of warranty experience. Although we currently maintain liability insurance coverage, we cannot assure that product liability claims, if made, would not exceed our insurance coverage limits or that insurance will continue to be available on commercially acceptable terms, if at all. The possibility exists for these types of warranty claims to result in costly product recalls, significant repair costs and damage to our reputation.
RISKS RELATED TO DATA SECURITY AND INTELLECTUAL PROPERTY
If we are not able to protect our intellectual property and other proprietary rights, we may be adversely affected.
Our success can be impacted by our ability to protect our intellectual property and other proprietary rights. We rely primarily on patents, trademarks, copyrights, trade secrets and unfair competition laws, as well as license agreements and other contractual provisions, to protect our intellectual property and other proprietary rights. However, filing, prosecuting and defending patents on our products in all countries and jurisdictions throughout the world would be prohibitively expensive. Moreover, existing U.S. legal standards relating to the validity, enforceability and scope of protection of intellectual property rights offer only limited protection, may not provide us with any competitive advantages and may be challenged by third parties. The laws of countries other than the United States may be even less protective of intellectual property rights. As a result, a significant portion of our technology is not patented, and we may be unable or may not seek to obtain patent protection for this technology. Further, although we routinely conduct anti-counterfeiting activities in multiple jurisdictions, we have encountered counterfeit reproductions of our products or products that otherwise infringe on our intellectual property rights. Counterfeit components of low quality may negatively impact our brand value. Accordingly, despite our efforts, we may be unable to prevent third parties from infringing upon, counterfeiting or misappropriating our intellectual property or otherwise gaining access to our technology. If we fail to protect our intellectual property and other proprietary rights, then our business, results of operations and financial condition could be negatively impacted.
In addition, we operate in industries in which there are many third-party owners of intellectual property rights. Owners of intellectual property that we need to conduct our business as it evolves may be unwilling to license such intellectual property rights to us on terms we consider reasonable. Third party intellectual property owners may assert infringement claims against us based on their intellectual property portfolios. If we are sued for intellectual property infringement, we may incur significant expenses investigating and defending such claims, even if we prevail.
We face cybersecurity and data protection risks relating to cyber-attacks and information technology failures that could cause loss of confidential information and other business disruptions.
We rely extensively on the security, stability, and availability of technology systems in our business. We also collect, process, and retain sensitive and confidential customer information, including proprietary business information, personal data and other information that may be subject to privacy and security laws, regulations and/or customer-imposed data protection controls. Our business may be adversely impacted by unintentional technology disruptions, including those resulting from programming errors, employee operational errors, software defects, and product vulnerabilities.
We also provide technological products integral to train operation. Accordingly, our business may be adversely impacted by disruptions to our own or third-party information technology infrastructure, which could result from cybersecurity incidents, including, but not limited to, unauthorized access to the Company’s information technology systems, data access or acquisition, and/or encryption of the Company’s environment. For instance, one of our vendors publicly disclosed vulnerabilities in its operating system that we use for certain Wabtec products. A successful exploitation of our own or our vendors’ information technology infrastructure could result in service interruptions, safety hazards, misappropriation of confidential information, process failures, security breaches or other operational difficulties. Such an event could result in decreased revenues and increased capital, insurance or operating costs, including the increased costs of security to protect the
23

Company’s infrastructure, among other results. Insurance maintained by the Company to protect against loss of business and other related consequences resulting from cyber incidents may not be sufficient to cover all damages. A disruption or compromise of the Company’s technology systems, even for short periods of time, could have a material adverse effect.
RISKS RELATED TO HUMAN CAPITAL
Labor shortages and labor disputes may have a material adverse effect on our operations and profitability.
We depend on skilled labor in our manufacturing and other businesses. Due to the competitive nature of the labor markets in which we operate, we may not be able to retain, recruit and train the personnel we require, particularly when the economy expands, production rates are high or competition for such skilled labor increases.
We collectively bargain with labor unions at some of our operations throughout the world. Failure to reach an agreement could result in strikes or other labor protests which could disrupt our operations. Furthermore, non-union employees in certain countries have the right to strike. If we were to experience a strike or work stoppage, it would be difficult for us to find a sufficient number of employees with the necessary skills to replace these employees. We cannot assure that we will reach any such agreement or that we will not encounter strikes or other types of conflicts with the labor unions of our personnel.
Any such labor shortages or labor disputes could have an adverse effect on our business, results of operations and financial condition, could cause us to lose revenues and customers and might have permanent effects on our business.
We rely on our management team and other key personnel.
We depend on the skills, working relationships, and continued services of key personnel, including our experienced management team, and other key employees. In addition, our ability to achieve our operating goals depends on our ability to identify, hire, train, and retain qualified individuals. We compete with other companies both within and outside of our industry for talented personnel, and we may lose key personnel or fail to attract, train, and retain other talented personnel. Any such loss or failure could adversely affect our product sales, financial condition, and operating results. If we lose key personnel, because they terminate their employment or retire, or as a result of illness, disability or death, or if an insufficient number of employees is retained to maintain effective operations, our business activities may be adversely affected and our management team's attention may be diverted. In addition, we may not be able to locate suitable replacements for any key personnel that we lose, or we may not be able to hire potential replacements on reasonable terms, all of which could adversely affect our product sales, financial condition, and operating results.
RISKS RELATED TO OUR INDEBTEDNESS
Our indebtedness could adversely affect our financial health.
At December 31, 2021, we had total debt of $4.1 billion, primarily related to Senior Notes. Being indebted could have important consequences to us. For example, our indebtedness could:
•increase our vulnerability to general adverse economic and industry conditions;
•require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, acquisitions and other general corporate purposes;
•limit our flexibility in planning for, or reacting to, changes in our business and the industries in which we operate;
•place us at a disadvantage compared to competitors that have less debt; and
•limit our ability to borrow additional funds.
Moreover, our Credit Agreement and the indentures governing our senior notes permit us to incur substantial additional indebtedness, which may further contribute to, or exacerbate the impact of, the foregoing impacts.
The indentures for our outstanding senior notes and our Credit Agreement contain various covenants that limit our management’s discretion in the operation of our businesses.
Our Credit Agreement subjects us to customary (i) affirmative covenants, including requirements with respect to certain reporting obligations on us and our subsidiaries, and (ii) negative covenants, including limitations on: indebtedness; liens; restricted payments; fundamental changes (including certain changes in control); business activities; transactions with affiliates; restrictive agreements; changes in fiscal year; and use of proceeds. In addition, we are required to maintain (i) a ratio of EBITDA to interest expense of at least 3.00 to 1.00 over each period of four consecutive fiscal quarters ending on the last day of a fiscal quarter and (ii) a Leverage Ratio, calculated as of the last day of a fiscal quarter for a period of four consecutive fiscal quarters, of 3.25 to 1.00 or less; provided that, in the second quarter of 2021, the Credit Agreement was amended so that we may, upon our request, increase the maximum Leverage Ratio to (x) 3.75 to 1.00 at the end of the fiscal quarter in which our acquisition of Nordco was consummated and each of the three fiscal quarters immediately following such fiscal quarter and (y)
24

3.50 to 1.00 at the end of each of the fourth and fifth full fiscal quarters after the consummation of such acquisition. The Company has not requested any such increase in the leverage ratio at this time.
The indentures under which our Senior Notes were issued contain covenants and restrictions which limit, subject to certain exceptions, certain sale and leaseback transactions with respect to principal properties, the incurrence of secured debt without equally and ratably securing the senior notes and certain merger and consolidation transactions. In addition, the indentures require that we offer to repurchase our outstanding Senior Notes upon the occurrence of certain change of control triggering events.

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

OVERVIEW
Wabtec is one of the world’s largest providers of locomotives, value-added, technology-based equipment, systems and services for the global freight rail and passenger transit industries. Our highly engineered products, which are intended to enhance safety, improve productivity and reduce maintenance costs for customers, can be found on most locomotives, freight cars, passenger transit cars and buses around the world. Our core products and services are essential in the safe and efficient operation of freight rail and passenger transit vehicles. Wabtec is a global company with operations in over 50 countries and our products can be found in more than 100 countries throughout the world. In 2021, approximately 60% of the Company’s net sales came from customers outside the U.S.
Wabtec’s long-term financial goals are to drive strong cash flow conversion, maintain a strong credit profile while minimizing our overall cost of capital, increase margins through strict attention to cost controls, drive improved efficiencies across the business, and increase revenues through a focused growth strategy, including product innovation and new technologies, global and market expansion, aftermarket products and services, and acquisitions. In addition, Management evaluates the Company’s current operational performance through measures such as safety, quality and on-time delivery.
The Company primarily serves the worldwide freight and transit rail industries. As such, our operating results are largely dependent on the level of activity, financial condition and capital spending plans of railroads and passenger transit agencies around the world, and transportation equipment manufacturers who serve those markets. Many factors influence these industries, including general economic conditions; traffic volumes, as measured by freight carloads and passenger ridership; government spending on public transportation; and investment in new technologies. In general, trends such as increasing urbanization, a focus on sustainability and environmental awareness, an aging equipment fleet, and growth in global trade are expected to drive continued investment in freight and transit rail.
The Company monitors a variety of factors and statistics to gauge market activity. Freight rail markets around the world are driven primarily by overall economic conditions and activity, while Transit markets are driven primarily by government funding and passenger ridership. Changes in these market drivers can cause fluctuations in demand for Wabtec's products and services.
Business Update
The COVID-19 pandemic has continued to impact our sales channels, supply chain, manufacturing operations, workforce and other key aspects of our operations. The Company continues to monitor the situation and guidance from international and domestic authorities, including federal, state, and local public health authorities; however, there are numerous uncertainties, including the duration and severity of the pandemic, availability and effectiveness of vaccines, impact of variants of the disease, actions that may be taken by governmental authorities and private industry, including preventing or curtailing the operations of our plants, the potential impact on global economic activity, global supply chain operations, our employees, our customers, suppliers and end-markets and other consequences that could negatively impact our business. We also face the possibility that government policies may become more restrictive especially if COVID-19 transmission rates increase in certain areas. As a result of these numerous uncertainties, we are unable to specifically predict the extent and length of time the COVID-19 pandemic will negatively impact our business.
The COVID-19 pandemic has increased the uncertainty around global economic and market conditions, which impacts our sales and operations. To the extent that these factors cause, or exacerbate, instability of capital markets, shortages of raw materials or component parts, longer sales cycles, deferral or delay of customer orders or an inability to market our products effectively, our business and results of operations could be materially adversely affected, and the materially adverse impacts that we have experienced as a result of the COVID-19 pandemic could continue or worsen. In addition, we face risks associated with our growth strategy including the level of investment that customers are willing to make in new technologies developed by the industry and the Company, and risks inherent in global expansion. When necessary, we will modify our financial and operating strategies to address changes in market conditions and risks.
Although the U.S. and other international governments deemed rail transportation as “critical infrastructure” providing essential services during the COVID-19 pandemic, the COVID-19 pandemic had a materially adverse impact on our operations and business results for the years ended December 31, 2021 and 2020, which is discussed in more detail in the Results of Operations section below. Supply chain disruptions and labor availability have caused component, raw material and chip shortages resulting in an adverse effect on the timing of the Company’s revenue generation. Additionally, broad-based inflation, escalation of metals and commodities costs, transportation and logistics costs and labor costs have all resulted from the COVID-19 pandemic. The Company has implemented various mitigating actions to lessen the impact of supply chain disruptions caused by the COVID-19 pandemic. These actions include price escalations in long-term contracts, implementing price surcharges, driving operational efficiencies through various cost mitigation efforts and discretionary spend management,
29

strategic sourcing alignments, and accelerating integration synergies where possible. The Company expects to continue to realize these increased costs over the next few quarters.
Uncertainty around general global economic and market conditions, exacerbated by the COVID-19 pandemic, will have an impact on our sales and operations in 2022 and beyond. To the extent that these factors cause instability of capital markets, supply chain disruptions including shortages of raw materials or component parts, labor availability, longer sales cycles, deferral or delay of customer orders, or an inability to market our products effectively, our business and results of operations could be materially adversely affected.
Cybersecurity Exposure
During the third quarter 2021, one of our vendors publicly disclosed vulnerabilities in one of its operating systems that is used in a range of products across the rail sector and other industries, including in certain Wabtec products. In response, Wabtec reviewed its digital onboard locomotive products and locomotive control systems to determine which products may be affected and the potential impact to Wabtec, our customers and other relevant parties. To date, we are unaware of any exploitation of these vulnerabilities; however, we are working closely with our vendor to appropriately address potentially impacted products. Additionally, we have communicated with potentially affected customers and discussed mitigation strategies.
ACQUISITIONS
Wabtec acquired Nordco, a leading North American supplier of new, rebuilt and used maintenance of way equipment, on March 31, 2021, and GE Transportation, a former business unit of GE, on February 25, 2019. For additional information related to these acquisitions refer to Note 3 of "Notes to Consolidated Financial Statements" included in Part IV, Item 15 of this report.

The following discussion compares our results for the year ended December 31, 2021 to the year ended December 31, 2020. The discussion comparing our results for the year ended December 31, 2020 to the year ended December 31, 2019 is included within Management's Discussion and Analysis of Financial Condition and Results of Operation in our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on February 19, 2021.
Net sales
Net sales for the year ended December 31, 2021 increased by $266 million, or 3.5%, to $7.82 billion compared to the same period in 2020. Organic sales decreased $6 million which is primarily attributable to a net organic decrease of $4 million in the Freight Segment. Services sales increased from higher locomotive modernizations and overhauls and a decrease in locomotive parkings while Components sales increased due to a higher railcar build and lower railcar parkings. These increases were offset by lower Equipment sales due to lower locomotive sales, particularly in North America and Egypt, and lower Digital Electronics sales primarily due to chip shortages caused by supply chain disruptions. These decreases in Freight were
31

offset by an increase in sales from acquisitions, which contributed $138 million, and favorable changes in foreign exchange rates increased sales by $134 million, primarily in the Transit segment.
Cost of sales
Cost of sales for the year ended December 31, 2021 increased by $34 million, or 0.6%, to $5.45 billion compared to the same period in 2020. The increase is primarily due to the increase in sales, increased metals, transportation and labor costs and higher restructuring costs. Cost of sales as a percentage of sales was 69.7% and 71.7% for the years ended December 31, 2021 and 2020, respectively, representing a 2.0 percentage point decrease. The decrease as a percentage of sales is primarily due to favorable product mix, improved productivity, synergy savings and the structural cost actions taken in the prior year, partially offset by the increase in the costs described above. Cost of sales for the year ended December 31, 2021 included $53 million of restructuring costs, primarily for footprint rationalization and headcount actions in Europe. Cost of sales for the year ended December 31, 2020 included $45 million of restructuring costs, primarily for footprint rationalization and related headcount actions as part of the acquisition of GE Transportation and in response to the COVID-19 pandemic.
Operating expenses
Total operating expenses increased $101 million, or 7.3%, for the year ended December 31, 2021 compared to the same period in 2020. Operating expenses as a percentage of sales was 19.1% and 18.4% for the year ended December 31, 2021 and 2020, respectively. Selling, general and administrative expenses ("SG&A") increased $82 million for the year ended December 31, 2021 compared to the same period in 2020. The increase is primarily due to higher employee compensation and benefit costs, costs incurred to support the higher sales volume and incremental expense from the acquisition of Nordco, partially offset by a decrease in restructuring and transaction costs. Restructuring and transaction costs included in SG&A were $25 million and $71 million for the year ended December 31, 2021 and 2020, respectively, and were primarily for headcount actions and footprint rationalization programs. Engineering expense increased $14 million primarily due to investments in new technology and incremental expense from the acquisition of Nordco. Amortization expense increased $5 million, due to the acquisition of Nordco.
Interest expense, net
Interest expense, net, decreased $22 million for the year ended December 31, 2021 over the same period in 2020 attributable to lower overall average debt balances and lower interest rates.
Other income, net
Other income, net, was $38 million of income in 2021 compared to $11 million of income in the same period of 2020. The increase is primarily attributable to foreign exchange gains in the current year compared to losses in the prior year as well as higher equity income in the current year.
Income taxes
The effective income tax rate was 23.2% and 26.0% in 2021 and 2020, respectively. The change in effective tax rate in 2021 is primarily the result of filing amended federal and state income tax returns in 2021. The Company amended the 2019 federal tax return to incorporate changes in tax regulations which generated a net operating loss that was carried back to tax years 2014 to 2016, which were at a higher federal tax rate. See Note 11 of "Notes to Consolidated Financial Statements" included in Part IV, Item 15 of this report for additional information.

2021 Net Sales |  | $ | 5,239 |

Net sales
Freight Segment sales increased by $157 million, or 3.1%, to $5.24 billion, compared to the same period in 2020, however, net organic sales decreased $4 million. Services sales increased from higher locomotive modernizations and overhauls and a decrease in locomotive parkings while Components sales increased due to a higher railcar build and lower railcar parkings. These increases were offset by lower Equipment Sales due to lower locomotive sales, particularly in North America and Egypt, and lower Digital Electronics sales primarily due to chip shortages caused by supply chain disruptions that have caused order delays but have not resulted in order cancellations. The organic sales decrease was more than offset by sales from acquisitions of $138 million and the effects of favorable foreign exchange rates of $23 million.
Cost of sales
Freight Segment cost of sales decreased by $22 million, to $3.57 billion, compared to the same period in 2020. The decrease is primarily due to favorable product mix, productivity and synergies and lower restructuring costs partially offset by increased metals, transportation and labor costs. Cost of sales as a percentage of sales was 68.2% and 70.7% for the years ended December 31, 2021 and 2020, respectively, representing a 2.5 percentage point decrease which also benefited from improved absorption of fixed costs. Cost of sales for the year ended December 31, 2021 includes $8 million of restructuring and transaction costs, primarily for amortization of the inventory step-up recorded in purchase accounting for the acquisition of Nordco and headcount actions as part of the ongoing integration of GE Transportation. Cost of sales for the year ended December 31, 2020 included $30 million of restructuring costs, primarily for costs for footprint rationalization and related headcount actions as part of the integration of GE Transportation and in response to the COVID-19 pandemic.
33

Operating expenses
Freight Segment operating expenses increased $46 million, or 5.1%, for the year ended December 31, 2021 compared to the same period in 2020. SG&A increased $31 million for the year ended December 31, 2021 compared to the same period in 2020. The increase is primarily due to higher employee compensation and benefit costs and incremental expense from the acquisition of Nordco, partially offset by a decrease in restructuring and transaction costs. Restructuring and transaction costs included in SG&A were $1 million and $46 million for the years ended December 31, 2021 and 2020, respectively, and were primarily for headcount actions and footprint rationalization as part of the integration of GE Transportation. Engineering expense increased $10 million primarily due to investments in new technology and incremental expense from the acquisition of Nordco. Amortization expense increased $5 million due to the acquisition of Nordco.

Net sales
Transit Segment sales for the year ended December 31, 2021 increased by $109 million, or 4.4%, to $2.58 billion compared to the same period in 2020, with foreign exchange rates being the primary driver of the increase. Transit segment organic sales decreased $2 million due to supply chain issues and disruptions caused by the COVID-19 pandemic.
Cost of sales
Transit Segment cost of sales for the year ended December 31, 2021 increased by $56 million, or 3.1%, to $1.88 billion compared to the same period in 2020. The increase is primarily due to higher restructuring costs, increased metals, transportation and labor costs and the effect of foreign exchange rates. Cost of sales as a percentage of sales was 72.8% and 73.8% for the years ended December 31, 2021 and 2020, respectively, representing a 1.0 percentage point decrease which also benefited from improved operational efficiency and the impact that the COVID-19 pandemic had on margins in 2020.

Although open purchase orders are considered enforceable and legally binding, their terms generally allow us the option to cancel, reschedule and adjust our requirements based on our business needs prior to the delivery of goods or performance of services.
(2)Operating leases represent multi-year obligations for rental of facilities and equipment.
(3)Pension and postretirement benefit payments includes expected payments to participants out of plan assets and corporate assets. The benefit payments are based on actuarial estimates using current assumptions for discount rates, expected return on long-term assets and rate of compensation increases. The Company expects to contribute $3 million to pension plan investments in 2022.
(4)Interest payments on the Senior Notes are based on interest rates in effect as of December 31, 2021 and are calculated on debt with maturities that extend to 2028. Interest payments for the Revolving Credit Facility and Other Borrowings are based on contractual terms and the Company’s current interest rates.
(5)Shareholder dividends are subject to approval by the Company’s Board of Directors, currently at an annual rate of approximately $111 million.
(6)Contingent consideration represents the total remaining payable to General Electric (GE) resulting from the 2019 acquisition of GE Transportation. The timing of the cash payments to GE is directly related to the future timing of tax benefits received by the Company and could change.
The above table does not reflect uncertain tax positions of $32 million, the timing of which are uncertain. Refer to Note 11 of the “Notes to Consolidated Financial Statements” for additional information on uncertain tax positions. Additionally, the Company arranges for certain types of bank guarantees and letters of credit, such as performance bonds, bid bonds and financial guarantees, that are issued by certain banks and insurance companies to support customer contracts. At December 31, 2021, the total value of these bank guarantees and letters of credit were $791 million and expire on various dates through 2039. Amounts include interest payments based on contractual terms and the Company’s current interest rate.

Critical Accounting Estimates
The preparation of the financial statements in accordance with generally accepted accounting principles requires Management to make judgments, estimates and assumptions regarding uncertainties that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. Areas of uncertainty that require judgments, estimates and assumptions include the accounting for allowance for doubtful accounts, inventories, business combinations, the testing of goodwill and other intangibles for impairment, warranty reserves, stock based compensation, income taxes, and revenue recognition. Management uses historical experience and all available information to make these judgments and estimates, and actual results will inevitably differ from those estimates and assumptions that are used to prepare the Company’s financial statements at any given time. Despite these inherent limitations, Management believes that Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) and the financial statements and related footnotes provide a meaningful and fair perspective of the Company.
A summary of the Company’s significant accounting policies is included in Note 2 in the “Notes to Consolidated Financial Statements” included in Part IV, Item 15 of this report. Management believes that the application of these policies on a consistent basis enables the Company to provide the users of the financial statements with useful and reliable information about the Company’s operating results and financial condition.
Accounts Receivable and Allowance for Doubtful Accounts:
Description The Company provides an allowance for doubtful accounts to cover anticipated losses on uncollectible accounts receivable.
Judgments and Uncertainties The allowance for doubtful accounts receivable reflects our best estimate of expected losses inherent in our receivable portfolio determined on the basis of historical experience, relevant credit forecast information, changes to customer's solvency and other currently available evidence.
Effect if Actual Results Differ From Assumptions If our estimates regarding the collectability of troubled accounts, and/or our actual losses within our receivable portfolio exceed our estimated losses, we may be exposed to the expense of increasing our allowance for doubtful accounts and loss of cash flows.
Inventories:
Description Inventories are stated at the lower of cost or net realizable value and are reviewed to ensure that an adequate provision is recognized for excess, slow moving and obsolete inventories, and net realizable value reserves.
Judgments and Uncertainties Cost is determined under the first-in, first-out (FIFO) method. Inventory costs include material, labor and overhead. The Company compares inventory components to prior year sales history and current backlog and anticipated future requirements. To the extent that inventory parts exceed estimated usage and demand, a reserve is recognized to reduce the carrying value of inventory. Also, specific reserves are established for known inventory obsolescence, a decline in market value, or loss of a customer with specific inventory.
Effect if Actual Results Differ From Assumptions If the market value or demand for our products were to decrease due to changing market conditions, the Company could be at risk of incurring write-downs to adjust inventory value to a net realizable value lower than stated cost. If our estimates regarding sales and backlog requirements are inaccurate, we may be exposed to the expense of increasing our reserves for slow moving and obsolete inventory.
42

Business Combinations:
Description The Company accounts for business acquisitions in accordance with ASC 805, Business Combinations, which requires the purchase price of the acquired business to be allocated to tangible and intangible assets acquired and liabilities assumed based on the respective fair values. The amount of purchase price which is in excess of the fair values of assets acquired and liabilities assumed is recognized as goodwill.
Judgments and Uncertainties Discounted cash flow models are used to estimate the fair values of acquired contract backlog, customer relationships, intellectual property intangibles and trade names, and below-market customer contract liabilities. The significant assumptions used to estimate the value of the intangible assets and below-market customer contract liabilities included revenue growth rates, projected profit margins, discount rates, royalty rates, customer attrition rates, revenue obsolescence rates and market participant profit margins. These significant assumptions are forward-looking and could be affected by future economic and market conditions.
Effect if Actual Results Differ From Assumptions Different assumptions may result in materially different values for assets acquired and liabilities assumed, which may impact the Company's financial position and future results of operations.
Goodwill and Indefinite-Lived Intangibles:
Description Goodwill and indefinite-lived intangibles are required to be tested for impairment at least annually. The Company performs its annual impairment test during the fourth quarter and more frequently when indicators of impairment are present. The Company reviews goodwill for impairment at the reporting unit level. The Company has identified three reporting units for purposes of testing goodwill for impairment. Two reporting units exist within the Freight segment and the Transit segment is also a reporting unit. The evaluation of impairment involves comparing the current fair value of the business to the recorded value (including goodwill).
Judgments and Uncertainties A number of significant assumptions and estimates are involved in the application of the impairment test, including the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, Wabtec specific events and share price trends and making the assessment on whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such amount.
Effect if Actual Results Differ From Assumptions Management considers historical experience and all available information at the time the fair values of its reporting units are estimated. However, actual amounts realized may differ from those used to evaluate the impairment of goodwill. If actual results are not consistent with our assumptions and judgments used in estimating future cash flows and asset fair values, we may be exposed to impairment losses that could be material to our results of operations. At December 31, 2021, all three of the Company’s reporting units had fair values which were substantially in excess of their carrying values. See Note 2 in the “Notes to Consolidated Financial Statements” included in Part IV, Item 15 of this report for additional discussion regarding impairment testing.
Warranty Reserves:
Description The Company provides warranty reserves to cover expected costs from repairing or replacing products with durability, quality or workmanship issues occurring during established warranty periods.
Judgments and Uncertainties In general, reserves are provided for as a percentage of sales, based on historical experience. In addition, specific reserves are established for known warranty issues and their estimable losses.
Effect if Actual Results Differ From Assumptions If actual results are not consistent with the assumptions and judgments used to calculate our warranty liability, the Company may be exposed to the expense of increasing our reserves for warranty expense.
Stock-based Compensation:
Description The Company has issued incentive stock units to eligible employees that vest upon attainment of certain cumulative three-year performance goals. The program is structured as a rolling three-year plan; each year starts a new three-year performance cycle with the most recently completed cycle being 2019-2021. No incentive stock units will vest for performance below the three-year cumulative threshold. The Company utilizes an economic profit measure for this performance goal. Economic profit is a measure of the extent to which the Company produces financial results in excess of its cost of capital. Based on the Company’s achievement of the threshold and three-year cumulative performance, the stock units vested can range from 0% to 200% of the shares granted.
Judgments and Uncertainties Significant judgments and estimates are used in determining the estimated three-year performance, which is then used to estimate the total shares expected to vest over the three year vesting cycle and corresponding expense based on the grant date fair value of the award. When determining the estimated three-year performance, the Company utilizes a combination of historical actual results, budgeted results and forecasts. Upon the initial grant of a performance cycle, the Company estimates the three-year performance at 100%. As actual performance results for a cycle begin to accumulate and the Company completes its budgeting and forecasting cycles the performance estimates are updated. These judgments and estimates are reviewed and updated on a quarterly basis.
43

Effect if Actual Results Differ From Assumptions If assumptions used in determining the estimated three-year performance change significantly, stock-based compensation expense related to the unvested incentive stock awards can fluctuate from period to period.
Income Taxes:
Description Wabtec records an estimated liability or benefit for income and other taxes based on what it determines will likely be paid in various tax jurisdictions in which it operates in accordance with ASC 740-10 Accounting for Income Taxes and Accounting for Uncertainty in Income Taxes.
Judgments and Uncertainties The estimate of our tax obligations are uncertain because Management must use judgment to estimate the exposures associated with our various filing positions, as well as realization of our deferred tax assets. ASC 740-10 establishes a recognition and measurement threshold to determine the amount of tax benefit that should be recognized related to uncertain tax positions.
Effect if Actual Results Differ From Assumptions Management uses its best judgment in the determination of these amounts. However, the liabilities ultimately realized and paid are dependent on various matters including the resolution of the tax audits in the various affected tax jurisdictions and may differ from the amounts recorded. An adjustment to the estimated liability would be recorded through income in the period in which new information changes the expected outcome of an uncertain tax position. A deferred tax valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized.
Revenue Recognition:
Description Revenue is recognized in accordance with ASC 606 Revenue from Contracts with Customers. Company recognizes a portion of its revenues on long-term customer agreements involving the design and production of highly engineered products that require revenue to be recognized over time because these products have no alternative use without significant economic loss and the agreements contain an enforceable right to payment including a reasonable profit margin from the customer in the event of contract termination. Generally, the Company uses an input method for determining the amount of revenue, cost and gross margin to recognize over time for these customer agreements. The input methods used for these agreements include costs of material and labor, both of which give an accurate representation of the progress made toward complete satisfaction of a particular performance obligation.
Judgments and Uncertainties Accounting for long-term customer agreements involves a judgmental process of estimating the total sales and costs for each contract, which results in the development of estimated profit margin percentages. Contract estimates related to long-term projects are based on various assumptions to project the outcome of future events that could span several years. These assumptions include cost of materials; labor availability and productivity; complexity of the work to be performed; and the performance of suppliers, customers and subcontracts that may be associated with the contract. Factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, asset utilization, and anticipated labor agreements. Generally, pricing is defined in our contracts but may include an estimate of variable consideration when required by the terms of the individual customer contract. Types of variable consideration that the Company typically has include volume discounts, prompt payment discounts, liquidating damages, and performance bonuses.
Effect if Actual Results Differ From Assumptions Should market conditions and customer demands dictate changes to our standard shipping terms, the Company may be impacted by longer than typical revenue recognition cycles. The development of expected contract costs and contract profit margin percentages involves procedures and personnel in all areas that provide financial or production information on the status of contracts. Due to the significance of judgments in the estimation process, it is likely that materially different revenue amounts could be recorded if we used different assumptions or if the underlying circumstances were to change. Changes in underlying assumptions/estimates, supplier performance, or circumstances may adversely or positively affect financial performance in future periods. Some of our contracts are expected to be completed in a loss position. Provisions are made currently for estimated losses on uncompleted contracts.

MANAGEMENT’S REPORTS TO WABTEC SHAREHOLDERS
Management’s Report on Financial Statements and Practices
The accompanying consolidated financial statements of Westinghouse Air Brake Technologies Corporation and subsidiaries (the “Company”) were prepared by Management, which is responsible for their integrity and objectivity. The statements were prepared in accordance with U.S. generally accepted accounting principles and include amounts that are based on Management’s best judgments and estimates. The other financial information included in the 10-K is consistent with that in the financial statements.
Management also recognizes its responsibility for conducting the Company’s affairs according to the highest standards of personal and corporate conduct. This responsibility is characterized and reflected in key policy statements issued from time to time regarding, among other things, conduct of its business activities within the laws of host countries in which the Company operates and potentially conflicting outside business interests of its employees. The Company maintains a systematic program to assess compliance with these policies.
Management’s Report on Internal Control over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. In order to evaluate the effectiveness of internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act, Management has conducted an assessment, including testing, using the criteria in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) (COSO). The Company’s system of internal control over financial reporting is 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. 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.
Management has excluded Nordco from its assessment of internal controls over financial reporting as of December 31, 2021 because the Company acquired Nordco effective March 31, 2021. Nordco is a subsidiary whose total assets and customer revenues represents 2.5% and 1.8%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2021.
Based on its assessment, Management has concluded that the Company maintained effective internal control over financial reporting as of December 31, 2021, based on criteria in Internal Control-Integrated Framework issued by the COSO. The effectiveness of the Company’s internal control over financial reporting as of December 31, 2021, has been audited by Ernst & Young LLP, independent registered public accounting firm, as stated in their report which is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and the Board of Directors of Westinghouse Air Brake Technologies Corporation
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Westinghouse Air Brake Technologies Corporation (the Company) as of December 31, 2021 and 2020, the related consolidated statements of income, comprehensive income, cash flows and shareholders' equity for each of the three years in the period ended December 31, 2021, and the related notes and financial statement schedule listed in the Index at Item 15.(2) (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, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, 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, 2021, 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 17, 2022 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.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

| Over Time Revenue Recognition for Long-Term Contracts
Description of the Matter | As described in Note 2 to the consolidated financial statements, the Company has long-term customer arrangements involving the design and production of highly engineered products that require revenue to be recognized over time. The Company uses input-based measures for determining the amount of revenue, cost and gross margin to recognize over time for these customer arrangements. The input methods used for these arrangements include costs of material and labor. During the year ended December 31, 2021, a material amount of the Company's total revenues were derived from performance obligations that are satisfied over time. Auditing the Company's measurement of revenue recognized over time on long-term contracts is especially challenging because it involves subjective management assumptions regarding the estimated remaining costs of the long-term contract that could span several years. These assumptions could be impacted by the future cost of materials, labor availability and productivity, complexity of the work to be performed, and the performance of suppliers, customers and subcontractors that may be associated with the contract and may be affected by future market or economic conditions.
How We Addressed the Matter in Our Audit | We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company's process to recognize revenue over time on long-term contracts, including controls over management’s review of the significant underlying assumptions described above. Our audit procedures also included, among others, evaluating the significant assumptions and the accuracy and completeness of the underlying data used in management's calculations. This included, for example, inspection of the executed contracts and testing management's cost estimates by comparing the inputs to the Company’s historical data or experience for similar contracts, the performance of sensitivity analysis and the performance of retrospective review analysis of prior management cost estimates to actual costs incurred for completed contracts. In addition, for a sample of contracts, we involved our construction and engineering specialists to assist in our evaluation of management’s cost estimates at completion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and the Board of Directors of Westinghouse Air Brake Technologies Corporation
Opinion on Internal Control over Financial Reporting
We have audited Westinghouse Air Brake Technologies Corporation’s internal control over financial reporting as of December 31, 2021, 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, Westinghouse Air Brake Technologies Corporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.
As indicated in the accompanying Management’s Report on Internal Control over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Nordco, which is included in the 2021 consolidated financial statements of the Company and constituted 2.5% of total assets as of December 31, 2021 and 1.8% of net sales for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of Nordco.
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, 2021 and 2020, the related consolidated statements of income, comprehensive income, cash flows and shareholders’ equity for each of the three years in the period ended December 31, 2021, and the related notes and financial statement schedule listed in the Index at Item 15.(2) and our report dated February 17, 2022 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 Management’s 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. BUSINESS
Wabtec is one of the world’s largest providers of locomotives, value-added, technology-based equipment, systems and services for the global freight rail and passenger transit industries. Our highly engineered products, which are intended to enhance safety, improve productivity and reduce maintenance costs for customers, can be found on most locomotives, freight cars, passenger transit cars and buses around the world. Our core products and services are essential in the safe and efficient operation of freight rail and passenger transit vehicles. Wabtec is a global company with operations in over 50 countries and our products can be found in more than 100 countries throughout the world. In 2021, approximately 60% of the Company’s net sales came from customers outside the U.S.
The COVID-19 pandemic had a materially adverse impact on our operations and business results for the years ended December 31, 2021, and 2020 which is discussed in more detail in the Results of Operations section in Part II, Item 7 of this report. COVID-19 has continued to impact our sales channels, supply chain, manufacturing operations, workforce, and other key aspects of our operations. Our top concern is, and remains, the health and well-being of our employees around the world. The outbreak and preventive measures taken to help curb the spread, including temporary plant closures during 2020 in China, India, Italy and other countries where outbreaks and stay-at-home orders were most prevalent, had an adverse impact on our operations and business results. Supply chain disruptions and labor availability have caused component and chip shortages resulting in an adverse effect on the timing of the Company’s revenue generation. Additionally, broad-based inflation, escalation of metals and commodities costs, transportation and logistics costs and labor costs have all resulted from the COVID-19 pandemic. The Company has implemented various mitigating actions to lessen the impact of supply chain disruptions caused by the COVID-19 pandemic. These actions include price escalations in long-term contracts, implementing price surcharges, driving operational efficiencies through various cost mitigation efforts and discretionary spend management, strategic sourcing alignments, and accelerating integration synergies where possible. The Company expects to continue to realize these increased costs over the next few quarters.
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Principles of Consolidation The consolidated financial statements include the accounts of the Company and all subsidiaries that it controls. For consolidated subsidiaries in which the Company's ownership is less than 100%, the outside shareholders' interests are shown as noncontrolling interests. These statements have been prepared in accordance with U.S. generally accepted accounting principles. Sales between subsidiaries are billed at prices consistent with sales to third parties and are eliminated in consolidation.
Cash Equivalents Cash equivalents are highly liquid investments purchased with an original maturity of three months or less.
Allowance for Doubtful Accounts The allowance for doubtful accounts receivable reflects our best estimate of expected losses inherent in our receivable portfolio determined on the basis of historical experience, relevant credit forecast information, changes to customer's solvency and other currently available evidence. The allowance for doubtful accounts was $32 million and $37 million as of December 31, 2021 and 2020, respectively.
Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined under the first-in, first-out (FIFO) method. Inventory costs include material, labor and overhead.
Property, Plant and Equipment Property, plant and equipment additions are stated at cost. Expenditures for renewals and improvements are capitalized. Expenditures for ordinary maintenance and repairs are expensed as incurred. The Company computes book depreciation principally on the straight-line method. Accelerated depreciation methods are utilized for income tax purposes.
Leasing Arrangements The Company conducts a portion of its operations from leased facilities and finances certain equipment purchases through lease agreements. In those cases in which the lease term approximates the useful life of the leased asset or the lease meets certain other prerequisites, the leasing arrangement is classified as a financing lease. The remaining arrangements are treated as operating leases. Right-of-use lease assets are classified as long-term assets under the caption "Other noncurrent assets" and lease liabilities are classified under the captions "Other accrued liabilities" and "Other long-term liabilities" on the Consolidated Balance Sheets.
Goodwill and Intangible Assets Goodwill and other intangible assets with indefinite lives are not amortized. Other intangibles (with definite lives) are amortized on a straight-line basis over their estimated economic lives. Amortizable intangible assets are reviewed for impairment when indicators of impairment are present. The Company tests goodwill and indefinite-lived intangible assets for impairment at the reporting unit level and at least annually. The Company performs its annual impairment test during the fourth quarter after the annual forecasting process is completed, and also tests for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Periodically,
60

Management of the Company assesses whether or not an indicator of impairment is present that would necessitate an impairment analysis be performed.
Equity Method Investments The Company invests in privately-held companies which are accounted for using the equity method. The equity method is applied in situations where the Company has the ability to exercise significant influence, but not control, over the investee. Equity method investments are classified as other assets under the caption "Other noncurrent assets" on the Consolidated Balance Sheets. Equity method investments were $96 million and $100 million at December 31, 2021 and 2020, respectively.
Depreciation Expense Depreciation of property, plant and equipment related to the manufacturing of products or services provided is included in Cost of goods or Cost of services. Depreciation of other property, plant and equipment that is not attributable to the manufacturing of products or services provided is included in Selling, general and administrative expenses or Engineering expense to the extent the property, plant, and equipment is used for research and development purposes.
Warranty Costs Warranty costs are accrued based on Management’s estimates of repair or upgrade costs per unit and historical experience.
Income Taxes Income taxes are accounted for under the liability method. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws. The provision for income taxes includes federal, state and foreign income taxes.
Stock-Based Compensation The Company recognizes compensation expense for stock-based compensation based on the grant date fair value amortized ratably over the requisite service period following the date of grant.
Financial Derivatives and Hedging Activities In the normal course of business, the Company is exposed to interest rate, commodity price and foreign currency exchange rate fluctuations. At times, the Company limits these risks through the use of derivatives such as cross-currency swaps, foreign currency forward contracts, interest rate swaps, commodity swaps and options. In accordance with the Company's policy, derivatives are only used for hedging purposes. The Company does not use derivatives for trading or speculative purposes. Foreign currency forward contracts are agreements with a counterparty to exchange two distinct currencies at a set exchange rate for delivery on a set date at some point in the future. There is no exchange of funds until the delivery date. At the delivery date, the Company can either take delivery of the currency or settle on a net basis. For further information regarding the foreign currency forward contracts see Note 17.
Foreign Currency Translation Certain of our international operations have determined that the local currency is the functional currency whereas others have determined the U.S. dollar is their functional currency. Assets and liabilities of foreign subsidiaries where the functional currency is the local currency are translated at the rate of exchange in effect on the balance sheet date while income and expenses are translated at the average rates of exchange prevailing during the period. Foreign currency gains and losses resulting from transactions and the translation of financial statements are recorded in the Company’s consolidated financial statements based upon the provisions of ASC 830 “Foreign Currency Matters.” The effects of currency exchange rate changes on intercompany transactions and balances of a long-term investment nature are accumulated and carried as a component of Accumulated other comprehensive loss. The effects of currency exchange rate changes on intercompany transactions that are denominated in a currency other than an entity’s functional currency are charged or credited to earnings. Foreign exchange transaction gains (losses) recognized in Other income, net were $8 million, $(8) million and $(14) million for 2021, 2020 and 2019, respectively.
Noncontrolling Interests In accordance with ASC 810, the Company has classified noncontrolling interests as equity on our consolidated balance sheets as of December 31, 2021 and 2020. Net (income) loss attributable to noncontrolling interests was not material for the years ended December 31, 2021, 2020 and 2019.
Revenue Recognition The Company accounts for Revenue under ASC 606 Revenue from Contracts with Customers. This guidance provides a five-step analysis of transactions to determine when and how revenue is recognized and requires entities to recognize revenue at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer.
A majority of the Company’s revenues are derived from performance obligations that are satisfied at a point in time when control passes to the customer which is generally at the time of shipment in accordance with agreed upon delivery terms. The remaining revenues are earned over time. All fees billed to the customer for shipping and handling are classified as a component of Net sales. All costs associated with shipping and handling are classified as a component of Cost of sales.
The Company also has long-term customer agreements involving the design and production of highly engineered products that require revenue to be recognized over time because these products have no alternative use without significant economic loss, and the agreements contain an enforceable right to payment including a reasonable profit margin from the customer in the event of contract termination. Additionally, the Company has customer agreements involving the creation or enhancement of an asset that the customer controls which also require revenue to be recognized over time. Generally, the
61

Company uses an input method for determining the amount of revenue, cost and gross margin to recognize over time for these customer agreements. The input methods used for these agreements include costs of material and labor, both of which give an accurate representation of the progress made toward complete satisfaction of a particular performance obligation. Contract revenues and cost estimates are reviewed and revised periodically throughout the year and adjustments are reflected in the accounting period as such amounts are determined. Additional information with respect to contract assets and liabilities is included in Note 8.
Due to the nature of work required to be performed on the Company’s long-term projects, the estimation of total revenue and cost at completion is subject to many variables and requires significant judgment. Contract estimates related to long-term projects are based on various assumptions to project the outcome of future events that could span several years. These assumptions include cost of materials; labor availability and productivity; complexity of the work to be performed; and the performance of suppliers, customers and subcontractors that may be associated with the contract. We have a disciplined process where management reviews the progress of long term-projects periodically throughout the year. As part of this process, management reviews information including key contract matters, progress towards completion, identified risks and opportunities and any other information that could impact the Company’s estimates of revenue and costs. After completing this analysis, any adjustments to net sales, cost of goods sold, and the related impact to operating income are recognized as necessary in the period they become known.
Generally, the Company’s revenue contains a single performance obligation for each distinct good or service; however, a single contract may have multiple performance obligations comprising multiple promises to customers. When there are multiple performance obligations, revenue is allocated based on the relative stand-alone selling price. Pricing is defined in our contracts on a line item basis and includes an estimate of variable consideration when required by the terms of the individual customer contract. Types of variable consideration the Company typically has include volume discounts, prompt payment discounts, price escalation clauses, liquidating damages, and performance bonuses. Sales returns and allowances are also estimated and recognized in the same period the related revenue is recognized, based upon the Company’s experience and future expectations.
Remaining performance obligations represent the allocated transaction price of unsatisfied or partially unsatisfied performance obligations. As of December 31, 2021, the Company's remaining performance obligations were approximately $22 billion. The Company expects to recognize revenue of approximately 25% of remaining performance obligations over the next 12 months, with the remainder recognized thereafter.
Revolving Receivables Program In May 2020, the Company entered into a revolving agreement to transfer up to $150 million of certain receivables of certain subsidiaries of the Company (the "Originators") through our bankruptcy-remote subsidiary to a financial institution on a recurring basis in exchange for cash equal to the gross receivables transferred. The bankruptcy remote subsidiary is a separate legal entity with its own creditors, and its assets are not available to pay creditors of the Company or any other affiliates of the Company. During the first quarter of 2021, the Company amended its revolving agreement to increase the amount of certain receivables that can be transferred from $150 million to $200 million. As customers pay their balances, we transfer additional receivables into the program, resulting in our gross receivables sold exceeding net cash flow impacts (e.g., collect and reinvest). The sold receivables are fully guaranteed by our bankruptcy-remote subsidiary that are pledged as collateral under this agreement. At December 31, 2021, and 2020 the bankruptcy-remote subsidiary held receivables of $324 million and $114 million, respectively. The transfers are recorded at the fair value of the proceeds received and obligations assumed less derecognized receivables. No obligation was recorded at December 31, 2021 or 2020 as the estimated expected credit losses on receivables sold is insignificant. Our maximum exposure to loss related to these receivables transferred is limited to the amount outstanding. The Company has agreed to guarantee the performance of the Originators respective obligations under the revolving agreement. None of the Company (except for the bankruptcy-remote consolidated subsidiary referenced above) nor the Originators guarantees the collectability of the receivables under the revolving agreements.
The following table sets forth a summary of receivables sold:

In millions |  | Twelve Months Ended December 31, 2021 | Twelve Months Ended December 31, 2020
Gross receivables sold/cash proceeds received |  | $ | 1,319 |  | $ | 852 |
Collections reinvested under revolving agreement |  | 1,372 |  | 779 |
Net cash proceeds (remitted) received |  | (53) |  | 73 |

Pre-Production Costs Certain pre-production costs relating to long-term production and supply contracts have been deferred and will be recognized over the life of the contracts. Deferred pre-production costs were $86 million and $87 million at December 31, 2021 and 2020, respectively.
Preferred Stock The Company’s authorized capital stock includes 1,000,000 shares of preferred stock. The Board of Directors has the authority to issue the preferred stock and to fix the designations, powers, preferences and rights of the shares
62

of each such class or series, including dividend rates, conversion rights, voting rights, terms of redemption and liquidation preferences, without any further vote or action by the Company’s shareholders. The rights and preferences of the preferred stock would be superior to those of the common stock. At December 31, 2021 and 2020 there was no preferred stock issued or outstanding.
Significant Customers and Concentrations of Credit Risk The Company’s trade receivables are primarily from rail and transit industry original equipment manufacturers, Class I railroads, railroad carriers and commercial companies that utilize rail cars in their operations, such as utility and chemical companies. No one customer accounted for more than 10% of the Company’s consolidated net sales in 2021, 2020 or 2019.
Reclassifications Certain prior year amounts have been reclassified, where necessary, to conform to the current year presentation.
Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual amounts could differ materially from the estimates. On an ongoing basis, Management reviews its estimates based on currently available information. Changes in facts and circumstances may result in revised estimates.
Accounting Standards Adopted in 2021
In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2019-12, Income Taxes: Simplifying the Accounting for Income Taxes. The amendments in this update simplify the accounting for certain income tax transactions by removing specific exceptions to the general principles in Accounting Standards Codification ("ASC") 740, "Income Taxes." This guidance was effective for fiscal years beginning after December 15, 2020 with early adoption permitted. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.
Accounting Standards Issued in 2021
In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendments in this update provide specific guidance on how to recognize and measure acquired contract assets and contract liabilities from revenue contracts in a business combination and address how to determine whether a contract liability is recognized by the acquirer in a business combination. The amendments in this update will be effective for Wabtec on January 1, 2023 and will be applied prospectively to business combinations occurring on or after the effective date.

3. ACQUISITIONS
Nordco
On March 31, 2021, the Company acquired Nordco, a leading North American supplier of new, rebuilt and used maintenance of way equipment. Nordco's products and services portfolio includes mobile railcar movers and ultrasonic rail flaw detection technologies. The purchase price paid for 100% ownership of Nordco was approximately $410 million.
The following table summarizes the preliminary fair value of the Nordco assets acquired and liabilities assumed:

In millions |  |
Assets acquired |  |
Cash and cash equivalents |  | $ | 5 |
Accounts receivable |  | 23 |
Inventory |  | 34 |
Other current assets |  | 2 |
Property, plant and equipment |  | 17 |
Goodwill |  | 214 |
Other intangible assets |  | 168 |
Other noncurrent assets |  | 12 |
Total assets acquired |  | 475 |
Liabilities assumed |  |
Current liabilities |  | 19 |
Noncurrent liabilities |  | 46 |
Total liabilities assumed |  | 65 |
Net assets acquired |  | $ | 410 |

The fair values of the assets acquired and liabilities assumed were determined using the income, cost and market approaches. Discounted cash flow models were used to estimate the fair values of acquired intangibles. The fair value measurements were primarily based on significant inputs that are not observable in the market and are considered Level 3 in the fair value hierarchy. These estimates are preliminary in nature and subject to adjustments, which could be material. Any necessary adjustments will be finalized within one year from the date of acquisition; adjustments to date have not been significant. Intangible assets acquired include customer relationships and intellectual property that are subject to amortization, and trade names that were assigned an indefinite life and are not subject to amortization. Contingent liabilities assumed as part of the transaction were not material.
Goodwill was calculated as the difference between the acquisition date fair value of the consideration transferred and the fair value of the net assets acquired, and represents the assembled workforce and the future economic benefits, including synergies, that are expected to be achieved as a result of the acquisition. The purchased goodwill is not expected to be deductible for tax purposes. The results of this business since the date of acquisition are reported within the Freight segment and the Services product line. The pro forma impact on Wabtec’s sales and results of operations, including the pro forma effect of events that are directly attributable to the acquisition, was not significant.
General Electric Transportation
Wabtec, General Electric Company ("GE"), GE Transportation, a Wabtec company formerly known as Transportation System Holdings Inc. ("SpinCo"), which was a newly formed wholly owned subsidiary of GE, and Wabtec US Rail Holdings, Inc. ("Merger Sub"), which was a newly formed wholly owned subsidiary of the Company, entered into the Original Merger Agreement on May 20, 2018, and GE, SpinCo, Wabtec and Wabtec US Rail, Inc. ("Direct Sale Purchaser") entered into the Original Separation Agreement on May 20, 2018, which together provided for the combination of Wabtec and GE Transportation. The Original Merger Agreement and Original Separation Agreement were subsequently amended on January 25, 2019 and the Merger was completed on February 25, 2019.
As part of the Merger, certain assets of GE Transportation, including the equity interests of certain pre-Transaction subsidiaries of GE that compose part of GE Transportation, were sold to Direct Sale Purchaser for a cash payment of $2.875 billion, and Direct Sale Purchaser assumed certain liabilities of GE Transportation in connection with this purchase (the "Direct Sale"). Thereafter, GE transferred the SpinCo business to SpinCo and its subsidiaries (to the extent not already held by SpinCo and its subsidiaries), and SpinCo issued to GE shares of SpinCo Class A preferred stock, SpinCo Class B preferred
64

stock, SpinCo Class C preferred stock and additional shares of SpinCo common stock. Following this issuance of additional SpinCo common stock to GE, and immediately prior to the Distribution (as defined below), GE owned 8,700,000,000 shares of SpinCo common stock, 15,000 shares of SpinCo Class A preferred stock, 10,000 shares of SpinCo Class B preferred stock and one share of SpinCo Class C preferred stock, which constituted all of the outstanding stock of SpinCo.
Following the Direct Sale, GE distributed the distribution shares of SpinCo in a spin-off transaction to its stockholder (the "Distribution"). Immediately after the Distribution, Merger Sub merged with and into SpinCo (the "Merger"), whereby the separate corporate existence of Merger Sub ceased and SpinCo continued as the surviving company and a wholly owned subsidiary of Wabtec (except with respect to shares of SpinCo Class A preferred stock held by GE). In the Merger, subject to adjustment in accordance with the Merger Agreement, each share of SpinCo common stock converted into the right to receive a number of shares of Wabtec common stock based on the common stock exchange ratio set forth in the Merger Agreement and the share of SpinCo Class C preferred stock was converted into the right to receive (a) 10,000 shares of Wabtec convertible preferred stock and (b) a number of shares of Wabtec common stock equal to 9.9% of the fully-diluted pro forma Wabtec shares. Immediately prior to the Merger, Wabtec paid $10 million in cash to GE in exchange for all of the shares of SpinCo Class B preferred stock.
Upon consummation of the Merger, Wabtec issued 46,763,975 shares of common stock to the holders of GE common stock, 19,018,207 shares of common stock to GE and 10,000 shares of preferred stock to GE and made a cash payment to GE of $2.885 billion. As a result and calculated based on Wabtec’s outstanding common stock on a fully-diluted, as-converted and as-exercised basis, as of February 25, 2019, approximately 49.2% of the outstanding shares of Wabtec common stock was held collectively by GE and holders of GE common stock (with 9.9% held by GE directly in shares of Wabtec common stock and 15% underlying the shares of Wabtec convertible preferred stock held by GE) and approximately 50.8% of the outstanding shares of Wabtec common stock would be held by pre-Merger Wabtec stockholders, in each case calculated on a fully-diluted, as-converted and as-exercised basis. Following the Merger, GE also retained 15,000 shares of SpinCo Class A non-voting preferred stock, and Wabtec held 10,000 shares of SpinCo Class B non-voting preferred stock.
After the Merger, SpinCo, which is Wabtec’s wholly owned subsidiary (except with respect to shares of SpinCo Class A preferred stock held by GE), and Direct Sale Purchaser, which also is Wabtec’s wholly owned subsidiary, together, SpinCo and Direct Sale Purchaser own and operate the post-transaction GE Transportation. All shares of the Company’s common stock, including those issued in the Merger, are listed on the NYSE under the Company’s current trading symbol “WAB.” On the date of the Distribution, GE and SpinCo, directly or through subsidiaries entered into additional agreements relating to, among other things, intellectual property, employee matters, tax matters, research and development and transition services.
On May 6, 2019, GE completed the sale of approximately 8,780 shares of Wabtec's Series A Preferred stock which converted upon the sale to 25,300,000 shares of Wabtec's common stock. On August 9, 2019, GE completed a sale of the remaining shares of Series A Preferred Stock outstanding which converted to approximately 3,515,500 shares of common stock, as well as 16,969,656 shares of common stock owned directly by GE. Finally, on September 12, 2019, GE completed a sale of all of its remaining shares of common stock of Wabtec, approximately 2,048,515 shares. In conjunction with these secondary offerings, the Company waived the requirements under the shareholders agreement for GE to maintain certain ownership levels of Wabtec's stock following the closing date of the Merger. The Company did not receive any proceeds from the sale of any of these shares.
Total future consideration to be paid by Wabtec to GE included a fixed payment of $470 million, of which $99 million and $115 million were paid during 2021 and 2020, respectively, which is directly related to the timing of tax benefits expected to be realized by Wabtec as a result of the acquisition of GE Transportation. This payment is considered contingent consideration because the timing of cash payments to GE is directly related to the future timing of tax benefits received by the Company as a result of the acquisition of GE Transportation. The estimated total value of the consideration to be paid by Wabtec in the acquisition transactions is approximately $10.3 billion, including the cash paid for the Direct Sales Assets, equity transferred for SpinCo, contingent consideration, assumed debt and net of cash acquired. The consideration is based on the Company’s closing share price of $73.36 on February 22, 2019 and the fair value of the contingent consideration.
The fair values of the assets acquired and liabilities assumed were determined using the income, cost and market approaches. Discounted cash flow models were used to estimate the fair values of acquired contract backlog, customer relationships, intellectual property intangibles, and below-market customer contracts liabilities. The fair value measurements were primarily based on significant inputs that are not observable in the market and are considered Level 3. The noncontrolling interest includes equity interests in GE Transportation's Brazil operations held by third parties on the date of acquisition. At the time of acquisition, quotable market prices of the noncontrolling interest existed; therefore, the noncontrolling interest in the GE Transportation Brazil operations were measured using a Level 1 input. In April 2019, the Company acquired the noncontrolling interest in GE Transportation's Brazil operations for $56 million which approximated the fair value assigned to the noncontrolling interest on the date of acquisition. The remaining noncontrolling interest value was determined based on inputs that are not observable in the market and are considered Level 3.

The following table summarizes the final fair value of the GE Transportation assets acquired and liabilities assumed:

In millions |  |
Assets acquired |  |
Cash and cash equivalents |  | $ | 177 |
Accounts receivable |  | 541 |
Inventories |  | 1,190 |
Other current assets |  | 71 |
Property, plant, and equipment |  | 1,089 |
Goodwill |  | 5,984 |
Trade names |  | 55 |
Customer relationships |  | 550 |
Intellectual property |  | 1,180 |
Backlog |  | 1,450 |
Other noncurrent assets |  | 321 |
Total assets acquired |  | 12,608 |
Liabilities assumed |  |
Current liabilities |  | 1,594 |
Contingent consideration |  | 440 |
Other noncurrent liabilities |  | 667 |
Total liabilities assumed |  | 2,701 |
Net assets acquired |  | 9,907 |
Noncontrolling interest |  | $ | 88 |

The revisions to the initial estimates were based on information that existed at the date of the acquisition. Trade names, customer relationships, patents and backlog intangible assets are subject to amortization. Customer relationship and backlog intangible assets are amortized using the straight-line method of amortization using a shortened estimated useful life then the projected future cash flow benefits of the intangible assets. Contingent liabilities assumed as part of the transaction were not material and are related to legal and tax matters. Contingent liabilities are recorded at fair value in purchase accounting, aside from those pertaining to uncertainty in income taxes which are an exception to the fair value basis of accounting. Included in other noncurrent liabilities are approximately $525 million of customer contracts whose terms are unfavorable compared to market terms at the date of consummation of the GE Transportation acquisition.
Goodwill was calculated as the difference between the acquisition date fair value of the consideration transferred and the fair value of the net assets acquired, and represents the future economic benefits, including synergies, and assembled workforce, that are expected to be achieved as a result of the consummation of the acquisition of GE Transportation. A majority of the purchased goodwill is expected to be deductible for tax purposes. The goodwill has been allocated to the Freight segment.
Costs related to the acquisition and integration of GE Transportation were approximately $3 million, $48 million and $63 million for the years ended December 31, 2021, 2020 and 2019, respectively, and are included in Selling, general and administrative expenses on the Consolidated Statements of Income.
The following unaudited pro forma consolidated financial information presents income statement results as if the GE Transportation acquisition had occurred January 1, 2018:

Building and improvements |  | 20 to 40
Machinery and equipment |  | 3 to 15

Depreciation expense was $198 million, $183 million, and $158 million for 2021, 2020 and 2019, respectively.
7. INTANGIBLES
Goodwill and indefinite lived intangible assets are reviewed annually during the fourth quarter for impairment. For 2021, the Company opted to proceed directly to the quantitative impairment test for all reporting units with goodwill. The discounted cash flow method and the market approach were used to estimate the fair value of each reporting unit using a weighting of 75% and 25%, respectively. The discounted cash flow model requires several assumptions including future sales growth, EBIT (earnings before interest and taxes) margins, capital expenditures, a discount rate and a terminal revenue growth rate (the revenue growth rate for the period beyond the years forecasted by the reporting units) for each reporting unit. The market approach requires several assumptions including EBITDA (earnings before interest, taxes, depreciation and amortization) multiples for comparable companies that operate in the same markets as the Company’s reporting units. For 2021, the discounted cash flow method was given more weight compared to the market approach due to a relatively reduced amount of publicly available data from companies with comparable operations to those of Wabtec; however, both valuations resulted in a conclusion that the estimated fair value of all three of the Company's reporting units was in excess of their respective carrying value, which resulted in a conclusion that no impairment existed.
Additionally, the Company proceeded directly to the quantitative impairment test for some trade names with indefinite lives. The fair value of all material trade names subject to the quantitative impairment test exceeded its respective carrying value, resulting in a conclusion that no material impairment existed. For trade names not subject to the quantitative testing, the Company opted to perform a qualitative trade name impairment assessment and determined from the qualitative assessment that it was not more likely than not that the estimated fair values of the trade names were less than their carrying values; therefore, no further analysis was required. In assessing the qualitative factors to determine whether it is more likely than not that the fair value of a trade name is less than its carrying amount, the Company assessed relevant events and circumstances that may impact the fair value and the carrying amount of the trade name. The identification of relevant events and circumstances and how these may impact a trade name’s fair value or carrying amount involve significant judgments and assumptions. The judgment and assumptions include the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, Wabtec specific events, share price trends and making the assessment on whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact.
The change in the carrying amount of goodwill by segment is as follows:

In millions |  | Freight Segment |  | Transit Segment |  | Total
Balance at December 31, 2019 |  | $ | 6,877 |  |  | $ | 1,484 |  |  | $ | 8,361 |
Additions |  | 2 |  |  | — |  |  | 2 |
Disposals |  | (6) |  |  | — |  |  | (6) |
Foreign currency impact |  | (1) |  |  | 129 |  |  | 128 |
Balance at December 31, 2020 |  | $ | 6,872 |  |  | $ | 1,613 |  |  | $ | 8,485 |
Additions |  | 214 |  |  | 15 |  |  | 229 |
Foreign currency impact |  | (13) |  |  | (114) |  |  | (127) |
Balance at December 31, 2021 |  | $ | 7,073 |  |  | $ | 1,514 |  |  | $ | 8,587 |

As of December 31, 2021 and 2020, the Company’s trade names had a net carrying amount of $635 million and $651 million, respectively, and the Company believes these intangibles have indefinite lives, with the exception of the right to use the GE Transportation trade name, to which the Company has assigned a useful life of 5 years.
68

Intangible assets of the Company, other than goodwill and trade names, consist of the following:

|  | December 31,
In millions |  | 2021 |  | 2020
Intellectual property, patents, and other intangibles, net of accumulated amortization of $334 and $223 |  | $ | 977 |  |  | $ | 1,008 |
Backlog, net of accumulated amortization of $309 and $206 |  | 1,114 |  |  | 1,224 |
Customer relationships, net of accumulated amortization of $331 and $276 |  | 979 |  |  | 986 |
Total |  | $ | 3,070 |  |  | $ | 3,218 |

The remaining weighted average useful lives of backlog, intellectual property, customer relationships, and other intangibles were 10 years, 11 years, 17 years, and 9 years, respectively. The backlog intangible primarily consists of in-place long-term service agreements acquired by the Company in conjunction with the acquisition of GE Transportation. Amortization expense for intangible assets was $287 million, $282 million, and $238 million for the years ended December 31, 2021, 2020, and 2019, respectively.
Estimated amortization expense for the five succeeding years is as follows (in millions):

2022 |  | $ | 291 |
2023 |  | $ | 290 |
2024 |  | $ | 281 |
2025 |  | $ | 278 |
2026 |  | $ | 274 |

8. CONTRACT ASSETS AND CONTRACT LIABILITIES
Contract assets include unbilled amounts resulting from sales under long-term contracts where revenue is recognized over time and revenue exceeds the amount that can be billed to the customer based on the terms of the contract. The current portion of the contract assets are classified as current assets under the caption “Unbilled accounts receivable” while the noncurrent contract assets are classified as other assets under the caption "Other noncurrent assets" on the Consolidated Balance Sheets. Noncurrent contract assets were $153 million and $101 million at December 31, 2021 and 2020, respectively. Included in noncurrent contract assets are certain costs that are specifically related to a contract, however, do not directly contribute to the transfer of control of the tangible product being created, such as pre-production costs. The Company has elected to use the practical expedient and not consider unbilled amounts anticipated to be paid within one year as significant financing components.
Contract liabilities include customer deposits that are made prior to the incurrence of costs related to a newly agreed upon contract and advanced customer payments that are in excess of revenue recognized. The current portion of contract liabilities are classified as current liabilities under the caption “Customer deposits” while the noncurrent contract liabilities are classified as noncurrent liabilities under the caption "Other long-term liabilities" on the Consolidated Balance Sheets. Noncurrent contract liabilities were $88 million and $80 million at December 31, 2021 and 2020, respectively. These contract liabilities are not considered a significant financing component because they are used to meet working capital demands that can be higher in the early stages of a contract and revenue associated with the contract liabilities is expected to be recognized within one year. Contract liabilities also include provisions for estimated losses from uncompleted contracts. Provisions for loss contracts were $107 million and $109 million at December 31, 2021 and 2020, respectively. These provisions for estimated losses are classified as current liabilities and included within the caption “Other accrued liabilities” on the Consolidated Balance Sheets.

1. See Note 17 for information on the fair value measurement of the Company's long-term debt.
2. During the second quarter of 2021, the Company repaid all outstanding term loan borrowings and related interest under the Senior Credit Facility and the 364 Day Facility.
3. U.S. dollar-denominated Term Loans includes the total outstanding balance of term loans denominated in U.S. dollars from the Senior Credit Facility and the 364 Day Facility.
Variances between Face Value and Book Value are the result of unamortized discounts and debt issuance fees.
The Company borrows and repays against the Multi-Currency Revolving loan facility for added flexibility in liquidity to manage cash during the operating cycle. The proceeds from borrowing and the repayments are included within the Financing Activities section of the Consolidated Statements of Cash Flows.
As of December 31, 2021, the annual repayment requirements for debt obligations are as follows:

In millions |
2022 | $ | 2 |
2023 | 250 |
2024 | 762 |
2025 | 500 |
2026 | 750 |
Thereafter | 1,817 |
Total | $ | 4,081 |

For those debt securities that have a premium or discount at the time of issuance, the Company amortizes the amount through interest expense based on the maturity date or the first date the holders may require the Company to repurchase the debt securities, if applicable. A premium would result in a decrease in interest expense, and a discount would result in an increase in interest expense in future periods. Additionally, the Company has debt issuance costs related to certain financing transactions which are also amortized through interest expense. As of December 31, 2021 and 2020, the Company had total unamortized debt issuance costs and discounts of $23 million and $21 million, respectively. At December 31, 2021, the weighted average interest rate on the Company's available variable debt facilities was 1.5%.
Credit Facilities
Senior Credit Facility
On June 8, 2018, the Company entered into a credit agreement ("Senior Credit Facility"), which replaced the Company's then-existing credit agreement. The Senior Credit Facility is with a syndicate of lenders and provides for borrowings consisting of (i) term loans denominated in euros and U.S. dollars ("Term Loans"); and (ii) a multi-currency revolving loan facility, providing for an equivalent in U.S. dollars of up to $1,200 million in multi-currency revolving loans (inclusive of swingline
71

loans of up to $75 million and letters of credit of up to $450 million (the "Revolving Credit Facility")). The Revolving Credit Facility will mature on June 8, 2023.
Under the Senior Credit Facility, we can elect to receive advances bearing interest based on either the ABR rate, the LIBOR rate or the adjusted risk free rate (each as defined in the Senior Credit Facility) plus applicable margin that is determined based on our credit ratings or the Company's Leverage. The agreement contains affirmative, negative and financial covenants, and events of default customary for facilities of this type. The obligations under the Senior Credit Facility are guaranteed by Wabtec and certain of Wabtec's U.S. subsidiaries, as guarantors.
The Company has agreed that, so long as any lender has any commitment under the Senior Credit Facility, any letter of credit is outstanding under the Senior Credit Facility, or any loan or other obligation is outstanding under the Senior Credit Facility, it will maintain the following as of the end of each fiscal quarter or the period of four quarters the ended:

Interest Coverage Ratio 1 |  | 3.0x
Leverage Ratio 2 |  | 3.25x

1. The interest coverage ratio is defined as EBITDA (earnings before interest, taxes, depreciation, and amortization), as defined in the Senior Credit Facility, to net interest expense for the four quarters then ended.
2. The leverage ratio is defined as net debt as of the last day of such fiscal quarter to EBITDA, as defined in the Senior Credit Facility for the four quarters then ended.
The Senior Credit Facility was amended in the second quarter of 2021 so the Company may increase the maximum leverage ratio to (x) 3.75 to 1.00 at the end of the fiscal quarter in which the Nordco acquisition was consummated and each of the three fiscal quarters immediately following such fiscal quarter and (y) 3.50 to 1.00 at the end of each of the fourth and fifth full fiscal quarters after the consummation of the Nordco acquisition upon the Company's request. The Company has not requested any increase in the leverage ratio at this time.
The Company was in compliance with all covenants in the Senior Credit Facility as of December 31, 2021.
The following table presents availability under the Revolving Facilities:

(in millions) |  | Revolving Credit Facility
Maximum Availability |  | $ | 1,200 |
Letters of Credit Under Credit Agreement |  | (3) |
Current Availability |  | $ | 1,197 |

364-Day Facility
On April 10, 2020 the Company entered into a new $600 million 364 day credit facility ("364 Day Facility") maturing April 2021 with a group of banks which included a $144 million revolving credit facility ("364 Day Revolver") and a $456 million term loan ("364 Term Loan"). The agreement called for interest at either a LIBOR-based rate, or a rate based on the prime lending rate of the agent bank, at the Company's option. The agreement contained affirmative, negative and financial covenants, and events of default customary for facilities of this type and substantially similar to our existing Senior Credit Facility. The obligations under the 364 Day Facility were guaranteed by certain of the Company's U.S. subsidiaries, as guarantors. On June 12, 2020, the Company amended the 364 Day Facility maturity to July 9, 2021. On June 3, 2021, the Company repaid all outstanding borrowings and related interest, effectively retiring the facility.
Senior Notes
The Company or its subsidiaries may issue senior notes from time to time. These notes are comprised of our 4.375% Senior Notes due 2023 (the "2023 Notes"), 4.15% Senior Notes due 2024 (the "2024 Notes"), 3.20% Senior Notes due 2025 (the "2025 Notes"), 3.45% Senior Notes due 2026 (the "2026 Notes"), 1.25% Senior Notes (EUR) due 2027 (the "Euro Notes" discussed below), and 4.70% Senior Notes due 2028 (the "2028 Notes"). The 2023 Notes, 2024 Notes, 2025 Notes, 2026 Notes and 2028 Notes are the “US Notes”, and collectively with the Euro Notes, the “Senior Notes.” Interest on the US Notes is payable semi-annually and interest on the Euro Notes is paid annually. Each series of the Senior Notes may be redeemed any time in whole or from time to time in part in accordance with the provisions of the indenture, under which such series of notes was issued. Each of the Senior Notes may be redeemed at a redemption price of 100% of the principal amount plus a specified make-whole premium and accrued interest. The US Notes and the Company's guarantee of the Euro Notes are senior unsecured obligations of the Company and rank pari passu with all existing and future senior debt and senior to all existing and future subordinated indebtedness of the Company.
On June 3, 2021, Wabtec Transportation Netherlands B.V. ("Wabtec Netherlands") issued €500 million of 1.25% Senior Notes due in 2027, which are fully and unconditionally guaranteed by the Company. The Euro Notes were issued at 99.267% of face value. Interest on the Euro Notes accrues at a rate of 1.25% per annum and is payable annually beginning December 3,
72

2021. The Company incurred approximately $4 million of deferred financing costs related to the issuance of the Euro Notes for total net proceeds of approximately $599 million after consideration of the discount.
On June 29, 2020, the Company issued $500 million of 3.20% Senior Notes due in 2025 (the "2025 Notes"). The 2025 Notes were issued at 99.892% of face value. Interest on the 2025 Notes accrues at a rate of 3.20% per annum and is payable semi-annually on June 15 and December 15 of each year beginning December 15, 2020. The proceeds were used to redeem outstanding variable rate debt. The Company incurred $2 million of deferred financing costs related to the issuance of the 2025 Notes.
The indentures under which the Senior Notes were issued contain covenants and restrictions which limit, subject to certain exceptions, certain sale and leaseback transactions with respect to principal properties, the incurrence of secured debt without equally and ratably securing the Senior Notes, and certain merger and consolidation transactions. The covenants do not require the Company to maintain any financial ratios or specified levels of net worth or liquidity. The US Notes are fully and unconditionally guaranteed, jointly and severally, on an unsecured basis by each of the Company's subsidiaries that is a guarantor under the Senior Credit Facility.
The Company is in compliance with the restrictions and covenants in the indentures under which the Senior Notes were issued and expects that these restrictions and covenants will not be any type of limiting factor in executing our operating activities.

Wabtec aggregates the Company's domestic cash position on a daily basis. Outside the United States, the Company uses cash pooling arrangements with banks to help manage our liquidity requirements. In these pooling arrangements, Wabtec subsidiary “Participants” agree with a single bank that the cash balances of any of the pool Participants with the bank will be subject to a full right of set-off against amounts other Participants owe the bank, and the bank provides for overdrafts as long as the net balance for all Participants does not exceed an agreed-upon level. Typically, each Participant pays interest on outstanding overdrafts and receives interest on cash balances. The Company's Consolidated Balance Sheets reflect cash, net of bank overdrafts, under all pooling arrangements.
Letters of Credit and Bank Guarantees
In the ordinary course of its business, the Company arranges for certain types of bank guarantees and letters of credit, such as performance bonds, bid bonds and financial guarantees, that are issued by certain banks and insurance companies to support customer contracts. The outstanding amount, including the letters of credit issued under the credit facility, were $791 million and $737 million at December 31, 2021 and 2020, respectively.

10. EMPLOYEE BENEFIT PLANS
Defined Benefit Pension Plans
The Company sponsors defined benefit pension plans that cover certain U.S., Canadian, German, and United Kingdom employees and which provide benefits of stated amounts for each year of service of the employee. The Company uses a December 31 measurement date for the plans.
The following tables provide information regarding the Company’s significant defined benefit pension plans summarized by U.S. and international components.

The discount rate is based on settling the pension obligation with high grade, high yield corporate bonds, and the rate of compensation increase is based on actual experience. The expected return on plan assets is based on historical performance as well as expected future rates of return on plan assets considering the current investment portfolio mix and the long-term investment strategy.

The amounts of net actuarial loss and prior service cost included in other comprehensive loss expected to be recognized as components of periodic benefit costs in 2022 are not material.
Pension Plan Assets
The Company has established formal investment policies for the assets associated with our pension plans. Objectives include maximizing long-term return at acceptable risk levels and diversifying among asset classes. Asset allocation targets are based on periodic asset liability study results which help determine the appropriate investment strategies. The investment policies permit variances from the targets within certain parameters. The plan assets consist primarily of equity security funds, debt security funds, insurance contracts, and temporary cash and cash equivalent investments. The assets held in these funds are generally actively managed and are valued at the net asset value per share multiplied by the number of shares held as of the measurement date. (See Note 17 “Fair Value Measurement” included herein). Plan assets by asset category at December 31, 2021 and 2020 are as follows:

|  | U.S. |  | International
In millions |  | 2021 |  | 2020 |  | 2021 |  | 2020
Pension Plan Assets |  |  |  |  |  |  |  |

Fair value of plan assets |  | $ | 40 |  |  | $ | 36 |  |  | $ | 307 |  |  | $ | 305 |

The U.S. plan has a target asset allocation of 75% equity securities and 25% debt securities. The International plan has a target asset allocation of 10% equity securities, 22% debt securities and 68% in other investments. Investment policies are determined by the respective Plan’s Pension Committee and set forth in its Investment Policy. Rebalancing of the asset allocation occurs on a quarterly basis.
The following tables summarize our pension plan assets measured at fair value on a recurring basis by fair value hierarchy level (See Note 17):

Cash Flows
The Company’s funding methods are based on governmental requirements and differ from those methods used to recognize pension expense. The Company expects to contribute $3 million to the international pension plan and does not expect to make a contribution to the U.S. pension plan during 2022.
Benefit payments expected to be paid to plan participants are as follows:

In millions |  | U.S. |  | International

Defined Contribution Plans
The Company participates in certain defined contribution plans. Costs recognized during 2021, 2020, and 2019 were approximately $55 million each year. The 401(k) savings plan is a participant directed defined contribution plan that holds shares of the Company’s stock as one of the investment options. At December 31, 2021 and 2020, the plan held on behalf of its participants approximately 387,000 shares with a market value of $36 million, and approximately 409,000 shares with a market value of $30 million, respectively.
11. INCOME TAXES
The Company is responsible for filing consolidated U.S., foreign and combined, unitary or separate state income tax returns. The Company is responsible for paying the taxes relating to such returns, including any subsequent adjustments resulting from the redetermination of such tax liabilities by the applicable taxing authorities.
The components of the income before income taxes for the Company’s domestic and foreign operations for the years ended December 31 are provided below:

A reconciliation of the United States federal statutory income tax rate to the effective income tax rate on operations for the years ended December 31 is provided below:

|  | For the year ended December 31,
In millions |  | 2021 |  | 2020 |  | 2019
U.S. federal statutory rate |  | 21.0 | % |  | 21.0 | % |  | 21.0 | %

Other, net |  | (1.0) |  |  | — |  |  | 0.7 |
Effective rate |  | 23.2 | % |  | 26.0 | % |  | 26.9 | %

The decrease in the effective tax rate is primarily the result of filing amended federal and state income tax returns in 2021. The Company amended the 2019 federal tax return to incorporate changes in tax regulations which generated a net operating loss that was carried back to tax years 2014 to 2016, which were at a higher federal tax rate. Other, net includes the impact of amended state returns reflecting changes in apportioned state income. These amendments resulted in a current year tax benefit. In addition, there was a decrease in the US tax reform provision resulting from the provisions of the Tax Cut and Jobs Act, a decrease in state tax expense and a decrease in foreign tax expense due to mix of taxable income which were partially offset by an increase in valuation allowances.

Components of deferred tax assets and liabilities were as follows:

Total deferred income tax assets |  | 445 |  |  | 409 |
Deferred income tax liabilities: |  |  |  |
Property, plant & equipment |  | 85 |  |  | — |
Right-of-use liability |  | 78 |  |  | 69 |
Intangibles |  | 503 |  |  | 444 |
Total deferred income tax liabilities |  | 666 |  |  | 513 |
Net deferred income tax liability |  | $ | 221 |  |  | $ | 104 |

A valuation allowance is recorded when it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of December 31, 2021, the valuation allowance for certain foreign deferred tax asset carryforwards was $(64) million primarily in China, Denmark, France, the Netherlands, South Africa, and the United States. The increase in valuation allowance in 2021 is primarily related to state net operating loss carry-forwards that are not expected to be realized.
The Company has net operating loss carry-forwards in the amount of $311 million, of which $192 million are indefinite lived, $66 million expire within ten years and $53 million expire in various periods between December 31, 2032 to December 31, 2041.
As of December 31, 2021, the liability for income taxes associated with unrecognized tax benefits was $32 million, of which $18 million, if recognized, would favorably affect the Company’s effective income tax rate. As of December 31, 2020, the liability for income taxes associated with unrecognized tax benefits was $16 million, of which $15 million, if recognized, would favorably affect the Company’s effective income tax rate. A reconciliation of the beginning and ending amount of the liability for income taxes associated with unrecognized tax benefits follows:

In millions |  | 2021 |  | 2020 |  | 2019
Gross liability for unrecognized tax benefits at beginning of year |  | $ | 16 |  |  | $ | 17 |  |  | $ | 9 |
Gross increases - unrecognized tax benefits in prior periods |  | 19 |  |  | 4 |  |  | 10 |
Gross decreases - audit settlement during year |  | (1) |  |  | (5) |  |  | — |
Gross decreases - expiration of audit statute of limitations |  | (2) |  |  | — |  |  | (2) |
Gross liability for unrecognized tax benefits at end of year |  | $ | 32 |  |  | $ | 16 |  |  | $ | 17 |

The Company includes interest and penalties related to unrecognized tax benefits in income tax expense. As of December 31, 2021 and 2020, the total interest and penalties accrued was approximately $5 million.
With limited exception, the Company is no longer subject to examination by various U.S. and foreign taxing authorities for years before 2016. At this time, the Company believes that it is reasonably possible that unrecognized tax benefits of approximately $5 million may change within the next 12 months due to the expiration of statutory review periods and current examinations.

12. EARNINGS PER SHARE
The computation of earnings per share from operations is as follows:

|  | For the Year Ended December 31,
In millions, except per share data |  | 2021 |  | 2020 |  | 2019
Numerator |  |  |  |  |  |
Net income attributable to Wabtec common shareholders - basic |  | $ | 556 |  |  | $ | 413 |  |  | $ | 325 |
Add: dividends declared - preferred shares |  | — |  |  | — |  |  | 1 |
Net income attributable to Wabtec common shareholders - diluted |  | $ | 556 |  |  | $ | 413 |  |  | $ | 326 |
Denominator |  |  |  |  |  |
Weighted average shares outstanding - basic |  | 187.7 |  |  | 189.9 |  |  | 170.5 |
Effect of dilutive securities: |  |  |  |  |  |
Assumed conversion of preferred shares |  | — |  |  | — |  |  | 6.4 |
Assumed conversion of dilutive stock-based compensation plans |  | 0.4 |  |  | 0.5 |  |  | 0.4 |
Weighted average shares outstanding - diluted |  | 188.1 |  |  | 190.4 |  |  | 177.3 |
Net income per common share attributable to Wabtec shareholders |  |  |  |  |  |
Basic |  | $ | 2.96 |  |  | $ | 2.18 |  |  | $ | 1.91 |
Diluted |  | $ | 2.96 |  |  | $ | 2.17 |  |  | $ | 1.84 |

The Company’s non-vested restricted stock contains rights to receive non-forfeitable dividends, and thus are participating securities requiring the two-class method of computing earnings per share. The calculation of earnings per share for common stock shown above excludes the income attributable to the non-vested restricted stock from the numerator resulting in a variance between net income used in the numerator and Net income attributable to Wabtec shareholders shown within the Consolidated Statements of Income. Additionally, the weighted average share counts in the denominator excludes the dilutive impact of the respective non-vested restricted stock.
Approximately 0.4 million, and 0.3 million outstanding shares of Common Stock for the years ended December 31, 2020 and 2019, respectively, were not included in the computation of year-to-date diluted earnings per share because their exercise price exceeded the average market price of the Company's common stock.
13. STOCK-BASED COMPENSATION PLANS
As of December 31, 2021, the Company maintains employee stock-based compensation plans for stock options, restricted stock, and incentive stock units as governed by the 2011 Stock Incentive Compensation Plan, as amended and restated (the “2011 Plan”) and the 2000 Stock Incentive Plan, as amended (the “2000 Plan”). The 2011 Plan has a term through May 10, 2027 and as of December 31, 2021 the number of shares available for future grants under the 2011 Plan was 6,399,200 shares, which includes remaining shares to grant under the 2000 Plan. The Company also maintains a 1995 Non-Employee Directors’ Fee and Stock Option Plan as amended and restated (“the Directors Plan”). The Directors Plan, as amended, authorizes a total of 1,000,000 shares of Common Stock to be issued. Under the Directors Plan options issued become exercisable over a three-year vesting period and expire ten years from the date of grant, and restricted stock issued under the plan vests one year from the date of grant. The amount of restricted stock issued to non-employee directors as compensation for directors’ fees was as follows: 18,142 shares for 2021; 23,152 shares for 2020; and 15,729 shares for 2019. The total number of shares issued under the Directors Plan as of December 31, 2021 was 951,175 shares.
Stock-based compensation expense for all of the plans was $46 million, $20 million and $50 million for the years ended December 31, 2021, 2020 and 2019, respectively. The Company recognized associated tax benefits related to the stock-based compensation plans of $1 million, $2 million and $1 million for the respective periods. Included in the stock-based compensation expense for 2021 above is $3 million of expense related to stock options, $13 million related to non-vested restricted stock, $6 million related to restricted stock units, $1 million related to units issued for Directors’ fees and $23 million of expense related to incentive stock units. At December 31, 2021, unamortized compensation expense related to those stock options, non-vested restricted shares and incentive stock units expected to vest totaled $38 million and will be recognized over a weighted period of 1.3 years.
Stock Options Stock options are granted to eligible employees and directors at the fair market value, which is the average of the high and low Wabtec stock price on the date of grant. Under the 2011 Plan and the 2000 Plan, options become exercisable over a three year vesting period and expire 10 years from the date of grant.

Options outstanding at December 31, 2021 were as follows:

Range of exercise prices |  | Number of Options Outstanding |  | Weighted Average Exercise Price of Options Outstanding |  | Weighted Average Remaining Contractual Life |  | Number of Options Currently Exercisable |  | Weighted Average Exercise Price of Options Currently Exercisable

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

|  | For the year ended December 31,
|  | 2021 |  | 2020 |  | 2019
Dividend yield |  | 0.60 | % |  | 0.60 | % |  | 0.66 | %
Risk-free interest rate |  | 0.8 | % |  | 1.5 | % |  | 2.6 | %
Stock price volatility |  | 36.1 | % |  | 28.1 | % |  | 25.8 | %
Expected life (years) |  | 5.0 |  | 5.0 |  | 5.0
Weighted average fair value of options granted during the year |  | $ | 25.01 |  |  | $ | 21.05 |  |  | $ | 19.54 |

The dividend yield is based on the Company’s dividend rate and the current market price of the underlying common stock at the date of grant. Expected life in years is determined from historical stock option exercise data. Expected volatility is based on the historical volatility of the Company’s stock. The risk-free interest rate is based on the 7 years U.S. Treasury bond rates for the expected life of the option.
Restricted Stock and Incentive Stock Beginning in 2006 the Company adopted a restricted stock program. As provided for under the 2011 and 2000 Plans, eligible employees are granted restricted stock that generally vests over three years from the date of grant. Under the Directors Plan, restricted stock units vest one year from the date of grant.
81

In addition, the Company has issued incentive stock units to eligible employees that vest upon attainment of certain cumulative three-year performance goals. Based on the Company’s performance for each three year period then ended, the incentive stock units can vest and be awarded ranging from 0% to 200% of the initial incentive stock units granted. The incentive stock units included in the table below represent the number of shares that are expected to vest based on the Company’s estimate for meeting those established performance targets. As of December 31, 2021, the Company estimates that it will achieve 33%, 121% and 117% for the incentive stock awards expected to vest based on performance for the three year periods ending December 31, 2021, 2022, and 2023, respectively, and has recorded incentive compensation expense accordingly. If estimates of the number of these stock units expected to vest changes in a future accounting period, cumulative compensation expense could increase or decrease and will be recognized in the current period for the elapsed portion of the vesting period and would change future expense for the remaining vesting period.
Compensation expense for the non-vested restricted stock and incentive stock units is based on the closing price of the Company’s common stock on the date of grant and recognized over the applicable vesting period.
The following table summarizes the restricted stock activity and related information for the 2011 Plan, the 2000 Plan, and Directors Plan, and incentive stock units activity and related information for the 2011 Plan and the 2000 Plan with related information for the years ended December 31:

15. LEASES
The Company leases certain, property, buildings and equipment. For leases with terms greater than 12 months, the Company records the related asset and obligation at the present value of lease payments. Many of the Company's leases include rental escalation clauses, renewal options, and/or termination options that are factored into our determination of lease payments when appropriate. The Company does not separate lease and non-lease components. Operating lease expense for the years ended December 31, 2021, 2020, and 2019 were $59 million, $57 million, and $54 million, respectively. New operating leases of $80 million and $68 million were added during the years ended December 31, 2021 and 2020, respectively. Wabtec does not have material financing leases, short-term or variable leases or sublease income.
As most of the Company's leases do not provide a readily stated discount rate, the Company must estimate the rate to discount lease payments using its incremental borrowing rate. The Company has established discount rates by geographic region ranging from 1% to 9%.
Scheduled payments of Operating lease liabilities are as follows:

In millions | Operating Leases
2022 | $ | 60 |
2023 | 52 |
2024 | 47 |
2025 | 40 |

17. FAIR VALUE MEASUREMENT AND DERIVATIVE INSTRUMENTS
ASC 820 “Fair Value Measurements and Disclosures” defines fair value, establishes a framework for measuring fair value and explains the related disclosure requirements. ASC 820 indicates, among other things, that a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability and defines fair value based upon an exit price model.
Valuation Hierarchy. ASC 820 establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.
The Company’s cash and cash equivalents are highly liquid investments purchased with an original maturity of three months or less and are considered Level 1 on the fair value valuation hierarchy. The fair value of cash and cash equivalents approximated the carrying value at December 31, 2021 and December 31, 2020. The Company’s defined benefit pension plan assets consist primarily of equity security funds, debt security funds, insurance contracts, and temporary cash and cash equivalent investments. These investments are comprised of a number of investment funds that invest in a diverse portfolio of assets including equity securities, corporate and governmental bonds, and money markets. Trusts are valued at the net asset value (“NAV”) as determined by their custodian. NAV represents the accumulation of the unadjusted quoted close prices on the reporting date for the underlying investments divided by the total shares outstanding at the reporting dates (see Note 10). The Senior Notes are considered Level 2 based on the fair value valuation hierarchy. Contingent consideration related to the GE Transportation acquisition is considered Level 3 based on the fair value valuation hierarchy. At December 31, 2021 and 2020, $110 million and $130 million, respectively, were classified as "Other accrued liabilities" on the Company's Consolidated Balance Sheets and $141 million and $218 million, respectively, were included within long-term liabilities shown as "Contingent consideration" on the Company's Consolidated Balance Sheets. The fair value approximates the carrying value at December 31, 2021 and 2020.
Hedging Activities In the normal course of business, the Company is exposed to market risks related to interest rates, commodity prices and foreign currency exchange rate fluctuations, which may adversely affect our operating results and financial position. At times, we limit these risks through the use of derivatives such as cross-currency swaps, foreign currency forward contracts, interest rate swaps, commodity swaps and options. These hedging contracts are valued using broker quotations, or market transactions in either the listed or over-the counter markets. As such, these derivative instruments are classified within level 2. In accordance with our policy, derivatives are only used for hedging purposes. We do not use derivatives for trading or speculative purposes.
84

Foreign Currency Exchange Risk
The Company uses forward contracts to hedge forecasted foreign currency denominated sales of finished goods and future settlement of foreign currency denominated assets and liabilities. Derivatives used to hedge firm commitments relevant to sales and purchases and forecasted transactions to be realized with high probability that meet the criteria for hedge accounting are designated as cash flow hedges. The effective portion of gains and losses is deferred as a component of Accumulated other comprehensive loss and is recognized in earnings at the time the hedged item affects earnings, in the same line item as the underlying hedged item. For the years ended December 31, 2021, 2020 and 2019, the amounts reclassified into income were not material.
The Company has also established balance sheet risk management and net investment hedging programs to protect its balance sheet against foreign currency exchange rate volatility. We conduct our business worldwide in U.S. dollars and the functional currencies of our foreign subsidiaries, including euro, Indian rupee, British pound sterling, Australian dollars and several other foreign currencies. Changes in these foreign currency exchange rates could have a material adverse impact on our financial results that are reported in U.S. dollars. We are also exposed to foreign currency exchange rate risk related to our foreign subsidiaries, including intercompany loans denominated in non-functional currencies. We hedge these exposures using foreign currency swap contracts and cross-currency swaps to offset the potential income statement effects on intercompany loans denominated in non-functional currencies. These programs reduce but do not eliminate foreign currency exchange rate risk entirely.
The Company enters into certain derivative contracts in accordance with its risk management strategy that do not meet the criteria for hedge accounting, but which have the impact of largely mitigating foreign currency exposure. These foreign exchange contracts are accounted for on a full mark to market basis through earnings, with gains and losses recorded as a component of Other income, net. The net (loss) gain related to these contracts were $(5), $(1) and $2 million for the years ended December 31, 2021, 2020 and 2019, respectively. These contracts typically mature within one year.
The following table summarizes the assets, liabilities, gross notional amounts, fair values, and fair value hierarchy classification of the designated and non-designated hedges discussed in the above sections as of December 31, 2021, which are included in other current assets and liabilities on the Consolidated Balance Sheets:

Interest Rate Risk
The Company may use interest rate swap contracts on certain investing and borrowing transactions to manage its net exposure to interest rate changes and to reduce its overall cost of borrowing. The Company does not use leveraged swaps and, in general, does not leverage any of its investment activities that would put principal capital at risk. For the years ended December 31, 2021, 2020 and 2019, the amounts reclassified into income were not material.
85

Commodity Price Risk
The Company may use commodity forward swaps to manage its exposure to commodity price changes and to reduce its overall cost of manufacturing. For the years ended December 31, 2021, 2020 and 2019, the amounts reclassified into income were not material.
18. COMMITMENTS AND CONTINGENCIES
The Company is subject to a variety of environmental laws and regulations governing discharges to air and water, the handling, storage and disposal of hazardous or solid waste materials and the remediation of contamination associated with releases of hazardous substances. The Company believes its operations currently comply in all material respects with all of the various environmental laws and regulations applicable to our business; however, there can be no assurance that environmental requirements will not change in the future or that we will not incur significant costs to comply with such requirements.
Claims have been filed against the Company and certain of its affiliates in various jurisdictions across the United States by persons alleging bodily injury as a result of exposure to asbestos-containing products. The vast majority of the claims are submitted to insurance carriers for defense and indemnity, or to non-affiliated companies that retain the liabilities for the asbestos-containing products at issue. We cannot, however, assure that all of these claims will be fully covered by insurance, or that the indemnitors or insurers will remain financially viable. Our ultimate legal and financial liability with respect to these claims, as is the case with other pending litigation, cannot be estimated. A limited number of claims are not covered by insurance, nor are they subject to indemnity from non-affiliated parties. Management believes that the costs of the Company’s asbestos-related cases will not be material to the Company’s overall financial position, results of operations and cash flows.
Xorail, Inc., a wholly owned subsidiary of the Company (“Xorail”), has received notices from Denver Transit Constructors (“DTC”) alleging breach of contract related to the operating of constant warning wireless crossings, and late delivery of the Train Management & Dispatch System (“TMDS”) for the Denver Eagle P3 Project, which is owned by the Denver Regional Transit District ("RTD"). No damages have been asserted for the alleged late delivery of the TMDS, and no formal claim has been filed; Xorail has successfully completed a remediation plan concerning the TMDS issues. With regard to the wireless crossing issue, as of September 8, 2017, DTC alleged that total damages were $37 million through July 31, 2017 and are continuing to accumulate. The majority of the damages stems from a delay in approval of the wireless crossing system by the Federal Railway Administration ("FRA") and the Public Utility Commission ("PUC"), resulting in the use of flaggers at all of the crossings pending approval of the wireless crossing system and certification of the crossings. DTC has alleged that the delay is due to Xorail's failure to achieve constant warning times for the crossings in accordance with the approval requirements imposed by the FRA and PUC. Xorail has denied DTC's assertions, stating that its system satisfied the contractual requirements. Xorail has worked with DTC to modify its system and implement the FRA's and PUC's previously undefined approval requirements; the FRA and PUC have both approved modified wireless crossing system, and as of August 2018, DTC completed the process of certifying the crossings and eliminated the use of flaggers. DTC has not updated its notices against Xorail, nor have they filed any formal claim against Xorail. On September 21, 2018, DTC filed a complaint against RTD in Colorado state court for breach of contract related to non-payments and the costs for the flaggers, asserting a change-in-law arising from the FRA/PUC’s new certification requirements. DTC’s complaint generally supports Xorail’s position and does not name or implicate Xorail. DTC's claim against RTD proceeded to trial on September 21, 2020; the trial has been completed, included post-trial submission.
From time to time the Company is involved in litigation relating to claims arising out of its operations in the ordinary course of business. As of the date hereof, the Company is involved in no litigation that the Company believes will have a material adverse effect on its financial condition, results of operations or liquidity.
19. SEGMENT INFORMATION
The Company has two reportable segments—the Freight Segment and the Transit Segment. The key factors used to identify these reportable segments are the organization and alignment of the Company’s internal operations, the nature of the products and services, and customer type. Initiatives to integrate GE Transportation operations into Wabtec including recent restructuring programs announced in late 2019 resulted in changes to the Company's organizational structure and the financial reporting utilized by the Company's chief operating decision maker to assess performance and allocate resources; as a result, certain asset groups were reorganized from the Freight Segment to the Transit Segment and vice versa. The change in the Company’s reportable segments was effective in the fourth quarter of 2019 and is reflected below. The Company believes these changes better present Management's view of the business. The Company’s business segments are:
Freight Segment primarily builds new locomotives, manufactures and services components for new and existing freight cars and locomotives, rebuilds freight locomotives, supplies railway electronics, positive train control equipment, signal design and engineering services, and provides related heat exchange and cooling systems. Customers include large, publicly traded railroads, leasing companies, manufacturers of original equipment such as locomotives and freight cars, and utilities. We refer
86

to sales of both goods, such as spare parts and equipment upgrades, and related services, such as monitoring, maintenance and repairs, as sales in our Services product line.
Transit Segment primarily manufactures and services components for new and existing passenger transit vehicles, typically regional trains, high speed trains, subway cars, light-rail vehicles and buses. It also refurbishes subway cars and provides heating, ventilation, and air conditioning equipment, and doors for buses and subways. Customers include public transit authorities and municipalities, leasing companies, and manufacturers of subway cars and buses around the world.
The Company evaluates its business segments’ operating results based on income from operations. Intersegment sales are accounted for at prices that are generally established by reference to similar transactions with unaffiliated customers. Corporate activities include general corporate expenses, elimination of intersegment transactions, interest income and expense and other unallocated charges.

Segment financial information for 2021 is as follows: |  |  |  |  |  |  |  |
In million |  | Freight Segment |  | Transit Segment |  | Corporate Activities and Elimination |  | Total
