PART I

ITEM 1. Business

OVERVIEW

We were founded in 1919 as Cummins Engine Company, a corporation in Columbus, Indiana and one of the first diesel engine manufacturers. In 2001, we changed our name to Cummins Inc. We are a global power leader that designs, manufactures, distributes and services diesel, natural gas, electric and hybrid powertrains and powertrain-related components including filtration, aftertreatment, turbochargers, fuel systems, controls systems, air handling systems, automated transmissions, electric power generation systems, batteries, electrified power systems, hydrogen production and fuel cell products. We sell our products to original equipment manufacturers (OEMs), distributors, dealers and other customers worldwide. We serve our customers through a network of over 500 wholly-owned, joint venture and independent distributor locations and over 9,000 Cummins certified dealer locations with service to approximately 190 countries and territories.

COVID-19

The outbreak of the coronavirus disease of 2019 (COVID-19) spread throughout the world and became a global pandemic with the resultant economic impacts evolving into a worldwide recession. The pandemic triggered a significant downturn in our markets globally, which continued to unfavorably impact market conditions throughout 2020 and these challenging market conditions could continue for an extended period of time. In an effort to contain the spread of COVID-19, maintain the well-being of our employees and stakeholders, match the reduced demand from our customers and in accordance with governmental requirements, we closed or partially shut down certain office, manufacturing, distribution and technical center facilities around the world in March 2020. Although most of our manufacturing, distribution and technical center facilities re-opened early in the second quarter of 2020, some operated at reduced capacities, most of our global office buildings remained closed through the remainder of 2020. Despite many of our markets recovering in the second half of 2020, the ongoing spread of the virus prior to widespread vaccination presents several risks to our business, especially in the first half of 2021.

COVID-19 vaccines are currently being administered around the world with the hope that the majority of the population will have access to the vaccine by the middle of 2021. If the distribution and the effectiveness of the vaccine are consistent with current government and health organization estimates, we anticipate the vaccine will mitigate the spread of the virus by the end of 2021 and allow a return to more normal operations in the second half of the year.

OPERATING SEGMENTS

We have five complementary operating segments: Engine, Distribution, Components, Power Systems and New Power. These segments share technology, customers, strategic partners, brand recognition and our distribution network in order to compete more efficiently and effectively in their respective markets. In each of our operating segments, we compete worldwide with a number of other manufacturers and distributors that produce and sell similar products. Our products primarily compete on the basis of performance, price, total cost of ownership, fuel economy, emissions compliance, speed of delivery, quality and customer support.

We use segment earnings or losses before interest expense, income taxes, depreciation and amortization and noncontrolling interests (EBITDA) as the primary basis for the Chief Operating Decision Maker to evaluate the performance of each of our reportable operating segments. We believe EBITDA is a useful measure of our operating performance as it assists investors and debt holders in comparing our performance on a consistent basis without regard to financing methods, capital structure, income taxes or depreciation and amortization methods, which can vary significantly depending upon many factors. See Note 22, "OPERATING SEGMENTS," to the Consolidated Financial Statements for additional information and a reconciliation of our segment information to the corresponding amounts in our Consolidated Statements of Net Income.

In the third quarter of 2019, we formed a joint venture with L'Air Liquide S.A. via the purchase of Hydrogenics Corporation, which was consolidated and included in our New Power segment. The Hydrogen Company, a wholly-owned subsidiary of L'Air Liquide S.A., maintains a 19 percent noncontrolling interest in Hydrogenics Corporation. See Note 20, "ACQUISITIONS", to the Consolidated Financial Statements for additional information.

SUPPLY

The performance of the end-to-end supply chain, extending through to our suppliers, is foundational to our ability to meet customers' expectations and support long-term growth. We are committed to having a robust strategy for how we select and manage our suppliers to enable a market focused supply chain. This requires us to continuously evaluate and upgrade our supply base, as necessary, to ensure we are meeting the needs of our customers.

We use a combination of proactive and reactive methodologies to enhance our understanding of supply base risks which guide the development of risk monitoring and sourcing strategies. Our category strategy process (a process designed to create the most value for the company) supports the review of our long-term needs and guides decisions on what we make internally and what we purchase externally. For the items we decide to purchase externally, the strategies also identify the suppliers we should partner with long-term to provide the best technology, the lowest total cost and highest supply chain performance. We design and/or manufacture our strategic components used in or with our engines and power generation units and New Power products. Key suppliers are managed through long-term supply and cost sharing agreements that assure capacity, delivery, quality and cost requirements are met over an extended period.

Other important elements of our sourcing strategy include:

• working with suppliers to measure and improve their environmental footprint;

• selecting and managing suppliers to comply with our supplier code of conduct; and

• assuring our suppliers comply with our prohibited and restricted materials policy.

PATENTS AND TRADEMARKS

We own or control a significant number of patents and trademarks relating to the products we manufacture. These patents and trademarks were granted and registered over a period of years. Although these patents and trademarks are generally considered beneficial to our operations, we do not believe any patent, group of patents or trademark (other than our leading brand house trademarks) is significant to our business.

SEASONALITY

While individual product lines may experience modest seasonal variation in production, there is no material effect on the demand for the majority of our products on a quarterly basis with the exception that our Power Systems segment normally experiences seasonal declines in the first quarter due to general declines in construction spending during this period.

LARGEST CUSTOMERS

We have thousands of customers around the world and have developed long-standing business relationships with many of them. PACCAR is our largest customer, accounting for 15 percent of our consolidated net sales in 2020, 17 percent in 2019 and 15 percent in 2018. We have long-term supply agreements with PACCAR for our heavy-duty and medium-duty engines and aftertreatment systems. While a significant number of our sales to PACCAR are under long-term supply agreements, these agreements provide for particular engine requirements for specific vehicle models and not a specific volume of engines or aftertreatment systems. PACCAR is our only customer accounting for more than 10 percent of our net sales in 2020. The loss of this customer or a significant decline in the production level of PACCAR vehicles that use our engines would have an adverse effect on our results of operations and financial condition. We have been an engine supplier to PACCAR for 76 years. A summary of principal customers for each operating segment is included in our segment discussion.

In addition to our agreement with PACCAR, we have long-term heavy-duty and medium-duty engine and aftertreatment system supply agreements with Navistar and Daimler. We also have an agreement with Chrysler to supply engines for its Ram trucks. Collectively, our net sales to these four customers, including PACCAR, were 32 percent of our consolidated net sales in 2020, 37 percent in 2019 and 35 percent in 2018. Excluding PACCAR, net sales to any single customer were less than 7 percent of our consolidated net sales in 2020, less than 9 percent in 2019 and less than 9 percent in 2018. These agreements contain standard purchase and sale agreement terms covering engine, aftertreatment and engine parts pricing, quality and delivery commitments, as well as engineering product support obligations. The basic nature of our agreements with OEM customers is that they are long-term price and operations agreements that help assure the availability of our products to each customer through the duration of the respective agreements. Agreements with most OEMs contain bilateral termination provisions giving either party the right to terminate in the event of a material breach, change of control or insolvency or bankruptcy of the other party.

BACKLOG

We have supply agreements with some truck and off-highway equipment OEMs, however most of our business is transacted through open purchase orders. These open orders are historically subject to month-to-month releases and are subject to cancellation on reasonable notice without cancellation charges and therefore are not considered firm. At December 31, 2020, we did not have any significant backlogs.

RESEARCH AND DEVELOPMENT

In 2020, we continued to invest in future critical technologies and products. We will continue to make investments to develop new products and improve our current technologies to meet future emission requirements around the world and improve fuel economy performance of diesel and natural gas-powered engines and related components as well as development activities around fully electric, hybrid and hydrogen power solutions and hydrogen production.

Our research and development programs are focused on product improvements, product extensions, innovations and cost reductions for our customers. Research and development expenditures include salaries, contractor fees, building costs, utilities, testing, technical IT, administrative expenses and allocation of corporate costs and are expensed, net of contract reimbursements, when incurred. From time to time, we enter into agreements with customers and government agencies to fund a portion of the research and development costs of a particular project. When not associated with a sales contract, we generally account for these reimbursements as an offset to the related research and development expenditure. Research and development expenses, net of contract reimbursements, were $903 million in 2020, $998 million in 2019 and $894 million in 2018. Contract reimbursements were $86 million, $90 million and $120 million in 2020, 2019 and 2018, respectively.

ENVIRONMENTAL SUSTAINABILITY

We are committed to making people's lives better by powering a more prosperous world. That prosperity includes strong communities, robust business and environmental sustainability.

Table of Contents

The highest level of accountability for our climate-related risks and opportunities is with the Safety, Environment and Technology (SET) Committee of the Board of Directors (the Board). The Action Committee for Environmental Sustainability meets monthly and reports to the Chairman and to the SET Committee at least annually.

In late 2019, we introduced PLANET 2050, a sustainability strategy focused on three priority areas: addressing climate change and air emissions, using natural resources in the most sustainable way and improving communities. The strategy includes eight specific goals to achieve by 2030, including science-based carbon dioxide reduction targets for newly sold products and facilities, as well as aspirational targets for 2050. We are currently evaluating how the new goals will be integrated into business planning and will report on progress beginning in 2022.

Our Sustainability Progress Report for 2019/2020 reports on environmental sustainability goals and commitments from our 2014 plan as well as other key environmental and climate metrics and targets. The 2014 plan goals were as follows:

•partnering with customers to improve the fuel efficiency of our products in use, targeting an annual run-rate reduction of 3.5 million metric tons of carbon dioxide;

•achieving a 32 percent energy intensity reduction from company facilities by the end of 2020 (using a baseline year of 2010) and increasing the portion of electricity we use derived from renewable sources;

•reducing direct water use by 50 percent adjusted for hours worked and achieving water neutrality at 15 sites by the end of 2020;

•increasing our recycling rate from 88 percent to 95 percent and achieving zero disposal at 30 sites by the end of 2020 and

•utilizing the most efficient methods and modes to move goods across our network to reduce carbon dioxide per kilogram of goods moved by 10 percent by the end of 2020.

Our progress through the end of 2020 will be summarized in our Sustainability Progress Report to be published later in 2021. This report is not incorporated by reference into this filing.

The most recent Sustainability Progress Report and prior reports, as well as a Data Book of more detailed environmental data in accordance with the Global Reporting Initiative's Standard core compliance designation, are available on our website at www.cummins.com. Our annual submission to the Carbon Disclosure Project (CDP) for climate change and water are also available on the website. The climate submission provides information on our scenario planning exercise for climate and other risks as requested by CDP. We also published our first report in accordance with the Sustainability Accounting Standards Board in 2020. These reports and data book are not incorporated into this Form 10-K by reference.

We continue to articulate our positions on key public policy issues and on a wide range of environmental issues. We are actively engaged with regulatory, industry and other stakeholder groups around the world as greenhouse gases (GHG) and fuel efficiency standards become more prevalent globally. We were named number 24 in Newsweek's Most Responsible Companies ranking, number 50 among Barron's Top 100 Most Sustainable Companies as well as named to the Dow Jones North American Sustainability Index for the fifteenth consecutive year in 2020.

ENVIRONMENTAL COMPLIANCE

Product Certification and Compliance

Our engines are subject to extensive statutory and regulatory requirements that directly or indirectly impose standards governing emissions and noise. Over the past several years we have increased our global environmental compliance presence and expertise to understand and meet emerging product environmental regulations around the world. Our ability to comply with these and future emission standards is an essential element in maintaining our leadership position in regulated markets. We have made, and will continue to make, significant capital and research expenditures to comply with these standards.

We strive to be a leader in developing and implementing technologies that provide customers with the highest performing products while minimizing the impact on the environment, and we have a long history of working with governments and regulators to achieve these goals. We remain committed to ensuring our products meet all current and future emission standards and delivering value to our customers.

Formed in 2019, the Product Compliance and Regulatory Affairs team leads both engine emissions certification and compliance and regulatory affairs initiatives. This organization is led by the Vice President - Product Compliance and Regulatory Affairs who reports directly to the Chief Executive Officer, and the new Vice President joins the Cummins Executive Team and Cummins Leadership Team. The focus of this organization is to strengthen our ability to design great products that help our customers win while ensuring compliance with increasingly challenging global emission regulations. The organization also works to enhance our collaboration with

Table of Contents

the agencies setting the direction and regulations of emissions to best ensure we are meeting every expectation today while planning for future changes.

Following conversations with the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) regarding certification for the engines in the 2019 RAM 2500 and 3500 trucks, we made the decision to review our certification process and compliance with emission standards. This review is being conducted with external advisers to ensure the certification and all of our processes for our pick-up truck applications are consistent with our internal policies, engineering standards and applicable laws. In addition, we voluntarily disclosed our formal internal review to the regulators and to other government agencies, the Department of Justice (DOJ) and the Securities and Exchange Commission (SEC), and worked cooperatively with them to ensure a complete and thorough review. We fully cooperated with the DOJ's and the SEC's information requests and inquiries and, based on recent communications with these agencies, we do not expect further inquiries. See Note 14, "COMMITMENTS AND CONTINGENCIES," to the Consolidated Financial Statements for additional information.

Engine Certifications

Our engines are certified globally through various categories within on-highway and off-highway applications. Regulations in these categories typically control nitrous oxides (NOx), particulate matter (PM) and GHG. The current on-highway NOx and PM emission standards came into effect in India on April 1, 2020, (BS VI), China on July 1, 2019, (NS VI), the EU on January 1, 2013, (Euro VI) and on January 1, 2010, for the EPA. To meet these regulations, mid-range and heavy-duty engines for India, China, EU and EPA require NOx aftertreatment. NOx reduction is achieved by an integrated technology solution comprised of the XPI High Pressure Common Rail fuel system, SCR technology (in some cases), next-generation cooled EGR, advanced electronic controls, proven air handling and the Cummins Diesel Particulate Filter (DPF). The Ministry of Road Transport and Highways, Ministry of Ecology and Environment, EU, EPA and CARB have certified that our engines meet the current emission requirements. Emission standards in international markets, including Japan, Mexico, Australia, Brazil and Russia are becoming more stringent. We believe that our experience in meeting the EU and EPA emission standards leaves us well positioned to take advantage of opportunities in these markets as the need for emission control capability grows.

In 2013, we certified to EPA's first ever GHG regulations for on-highway medium and heavy-duty engines. Additionally, the EPA 2013 regulations added the requirement of on-board diagnostics, which were introduced on the ISX 15 in 2010, across the full on-highway product line while maintaining the same near-zero emission levels of NOx and PM required in 2010. On-board diagnostics provide enhanced service capability with standardized diagnostic trouble codes, service tool interface, in-cab warning lamp and service information availability. The new GHG and fuel-efficiency regulations were required for all heavy-duty diesel and natural gas engines beginning in January 2014. Our GHG certification was the first engine certificate issued by the EPA and uses the same proven base engine with the XPI fuel system, variable geometry turbocharger (VGTTM) and Cummins aftertreatment system with DPF and SCR technology. Application of these engines and aftertreatment technologies continues in our products that comply with the 2021 GHG regulations.

Our off-highway engines designed for Tier 4 / Stage V standards were based on our extensive on-highway experience developing SCR, high pressure fuel systems, DPF and VGTTM. Our products offer low fuel consumption, high torque rise and power output, extended maintenance intervals, reliable and durable operation and a long life to overhaul period, all while meeting the most stringent emission standards in the industrial market. Our off-highway products power multiple applications including construction, mining, marine, agriculture, rail, defense and oil and gas and serve a global customer base. The current EPA Tier 4 off-highway emission standards came into effect between 2013-2015 for all engine power categories. The current EU Stage V off-highway emission standards became effective in 2019 for certain engine power categories and were completely effective January 2021 for all remaining categories.

Other Environmental Statutes and Regulations

Expenditures for environmental control activities and environmental remediation projects at our facilities in the U.S. have not been a substantial portion of our annual expenses and are not expected to be material in 2021. We believe we are in compliance in all material respects with laws and regulations applicable to our plants and operations.

In the U.S., pursuant to notices received from federal and state agencies and/or defendant parties in site environmental contribution actions, we have been identified as a potentially responsible party under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended or similar state laws, at fewer than 20 waste disposal sites.

Based upon our experiences at similar sites we believe that our aggregate future remediation costs will not be material. We have established accruals that we believe are adequate for our expected future liability with respect to these sites. In addition, we have several other sites where we are working with governmental authorities on remediation projects. The costs for these remediation projects are not expected to be material.

HUMAN CAPITAL RESOURCES

At December 31, 2020, we employed approximately 57,825 persons worldwide. Approximately 20,279 of our employees worldwide are represented by various unions under collective bargaining agreements that expire between 2021 and 2025.

Throughout our company’s 100-year history, we always recognized that people drive the strength of our business and our ability to effectively serve our clients and sustain our competitive position. We are focused on harmonizing our approach to talent to provide seamless opportunities and better experiences to our employees around the world. The disruptive events of 2020 gave even greater importance for us to complete the strategic work in Human Resources that calls for our company to “Inspire and Encourage All Employees to Reach Their Full Potential.” This strategy has key focus areas: creating a diverse and inclusive work environment; engaging employees and their families in improving wellness; developing self-aware and effective leaders; and extending our talent management philosophies in performance management, compensation management, competency building, and access to development opportunities to all employees.

Leadership and Talent Management

Managing our human capital resources is a key focus of the company. In 2020, the Board recast our Compensation Committee as the Talent Management and Compensation Committee to reflect the Board’s commitment to overseeing and providing guidance to our leadership team in this important work.

We strive to create a leadership culture that begins with authentic leaders who create an outstanding place to work by encouraging all employees to achieve their full potential. We encourage leaders to connect our people and their work to our mission, vision, values, brand promise and strategies of the company, motivating and giving them a higher sense of purpose. We have developed leadership and employee development programs for employees ranging from the manufacturing floor and technicians through middle management and executive development. When an individual joins Cummins, we are committed to providing both that employee and their manager with the tools and resources to manage their career and navigate in a large global organization. Through our Talent Management strategy our goal is to ensure all employees have access to the development and career opportunities that a global company enables.

Competitive Pay and Benefits

To attract and retain the best employees, we focus on providing competitive pay and benefits. Our programs target the market for competitiveness and sustainability while ensuring that we honor our core values. We provide benefit programs with the goal of improving physical, mental and financial wellness of our employees throughout their lifetime. Some examples include base and variable pay, medical, paid time off, retirement saving plans and employee stock purchase plans.

When designing our base pay compensation ranges, we do market analysis to be sure ranges are current and our employees are advancing their earning potential. We also do annual compensation studies to assess market movement, pay equity and living wages. For example, in 2018, we conducted a living wage analysis globally to ensure our employees were making a living wage in the countries they live and work. We incorporated this living wage assessment into our annual compensation structure to ensure that current and new hires never fall below this threshold. In the U.S. for example, the living wage in 2019 was $15 per hour, although most positions pay more than that. We continually review wages globally to ensure we are fair, equitable, competitive and can attract and retain the best talent.

We also provide diverse benefit programs that are aligned with our values and focused on supporting employees and their families based on their unique needs, some of which are: tiered health care cost so that more junior employees pay less for their premiums; paid parental leave for primary and secondary caregivers; advanced medical services from clinicians to support complex health care needs and employee assistance programs with diverse providers that can meet a range of employee needs from race related trauma to financial planning to transgender transition support.

Employee Safety and Wellness

Cummins is committed to being world-class in health and safety. We strive to ensure a workplace with zero incidents. We are committed to removing conditions that cause personal injury or occupational illness and we make decisions and promote behaviors that protect others from risk of injury. We publicly disclose metrics on our rate of recordable injuries, our rate of lost workdays due to injury and the rate of injuries involving contractors.

Our response to the COVID-19 global pandemic illustrated our commitment to safety. To support both our customers and communities, we made keeping employees safe our top priority. Most of our employees who can work from home have been doing so since the outbreak of the pandemic and we have provided them with the tools and support to do so. This allowed us to focus resources

Table of Contents

and investments on our engineering and production facilities. In those facilities, we have taken many steps to protect the health and safety of our people, including:

•Mandatory health screenings at our plants and facilities;

•Personal protective equipment for frontline employees;

•Masks required inside open plants and facilities;

•Redesigned exits, entrances and production lines to encourage social distancing;

•Enhanced cleaning protocols before, during and after shifts;

•Expanded healthcare and leave programs to support employees and their families; and

•Manufacturing our own face masks to provide to our employees free of charge.

Diversity, Equity and Inclusion

Diversity, equity and inclusion at all levels of the company are critical to our ability to innovate, to win in the marketplace and to create sustainable success. Having diverse, equitable and inclusive workplaces allows us to attract and retain the best employees to deliver results for our shareholders. This is exemplified by the composition of the Board of which 4 of 12 directors are female and 4 of 12 directors are ethnically diverse. In addition, 50 percent of our executive team is female and 40 percent of our leadership team is female. We disclose publicly the percentage of women in supervisory roles and the overall workforce. We also launched several initiatives to increase representation of minorities in the workplace. We have created a Global Inclusion Leadership Council to oversee more than 100 employee resource groups around the world to provide opportunities to employees from all backgrounds for leadership training, cross cultural learning and professional development. In 2020, we launched Cummins Advocating for Racial Equity (CARE), which seeks to drive a sustainable impact in dismantling institutional racism and creating systemic equity.

ITEM 1A. Risk Factors

Set forth below and elsewhere in this Annual Report on Form 10-K are some of the principal risks and uncertainties that could cause our actual business results to differ materially from any forward-looking statements contained in this Report and could individually, or in combination, have a material adverse effect on our results of operations, financial position and cash flows. These risk factors should be considered in addition to our cautionary comments concerning forward-looking statements in this Report, including statements related to markets for our products and trends in our business that involve a number of risks and uncertainties. Our separate section above, "CAUTIONARY STATEMENTS REGARDING FORWARD-LOOKING INFORMATION," should be considered in addition to the following statements.

GOVERNMENT REGULATION

We are conducting a formal internal review of our emission certification process and compliance with emission standards with respect to our pick-up truck applications and are working with the EPA and CARB to address their questions about these applications. The results of this formal review and regulatory processes, or the discovery of any noncompliance issues, could have a material adverse impact on our results of operations and cash flows.

We previously announced that we are conducting a formal internal review of our emissions certification process and compliance with emission standards with respect to all of our pick-up truck applications, following conversations with the EPA and CARB regarding certification of our engines for model year 2019 RAM 2500 and 3500 trucks. During conversations with the EPA and CARB about the effectiveness of our pick-up truck applications, the regulators raised concerns that certain aspects of our emissions systems may reduce the effectiveness of our emissions control systems and thereby act as defeat devices. As a result, our internal review focuses, in part, on the regulators’ concerns. We are working closely with the regulators to enhance our emissions systems to improve the effectiveness of all of our pick-up truck applications and to fully address the regulators’ requirements. Based on discussions with the regulators, we have developed a new calibration for the engines in model year 2019 RAM 2500 and 3500 trucks that has been included in all engines shipped since September 2019. During our discussions, the regulators have asked us to look at other model years and other engines. We will continue to work together closely with the relevant regulators to develop and implement recommendations for improvement as part of our ongoing commitment to compliance.

Due to the continuing nature of the formal review, our ongoing cooperation with the regulators and the presence of many unknown facts and circumstances, we are not yet able to estimate the financial impact of these matters. It is possible that the consequences of any remediation plans resulting from our formal review and these regulatory processes could have a material adverse impact on our results of operations and cash flows in the periods in which these emissions certification issues are addressed.

Our products are subject to extensive statutory and regulatory requirements that can significantly increase our costs and, along with increased scrutiny from regulatory agencies and unpredictability in the adoption, implementation and enforcement of increasingly stringent and fragmented emission standards by multiple jurisdictions around the world, could have a material adverse impact on our results of operations, financial condition and cash flows.

Our engines are subject to extensive statutory and regulatory requirements governing emissions and noise, including standards imposed by the EPA, the EU, state regulatory agencies (such as the CARB) and other regulatory agencies around the world. Regulatory agencies are making certification and compliance with emissions and noise standards more stringent and subjecting diesel engine products to an increasing level of scrutiny. The discovery of noncompliance issues could have a material adverse impact on our results of operations, financial condition and cash flows.

Developing engines and components to meet more stringent and changing regulatory requirements, with different implementation timelines and emission requirements, makes developing engines efficiently for multiple markets complicated and could result in substantial additional costs that may be difficult to recover in certain markets. While we have met previous deadlines, our ability to comply with existing and future regulatory standards will be essential for us to maintain our competitive position in the engine applications and industries we serve. 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 increasingly stringent emission standards in our worldwide markets are unpredictable and subject to change. Any delays in implementation or enforcement could result in a loss of our competitive advantage and could have a material adverse impact on our results of operations, financial condition and cash flows.

Table of Contents

We operate our business on a global basis and policy changes affecting international trade could adversely impact the demand for our products and our competitive position.

We manufacture, sell and service products globally and rely upon a global supply chain to deliver the raw materials, components, systems and parts that we need to manufacture and service our products. Changes in government policies on foreign trade and investment can affect the demand for our products and services, cause non-U.S. customers to shift preferences toward domestically manufactured or branded products and impact the competitive position of our products or prevent us from being able to sell products in certain countries. Our business benefits from free trade agreements, such as the new United States-Mexico-Canada Agreement and the U.S. trade relationship with China, Brazil and France and efforts to withdraw from, or substantially modify such agreements or arrangements, in addition to the implementation of more restrictive trade policies, such as more detailed inspections, higher tariffs (including, but not limited to, additional tariffs on the import of steel or aluminum), import or export licensing requirements, exchange controls or new barriers to entry, could adversely impact our production costs, customer demand and our relationships with customers and suppliers. Any of these consequences could have a material adverse effect on our results of operations, financial condition and cash flows.

The U.K.’s exit from the European Union (EU) could materially and adversely impact our results of operations, financial condition and cash flows.

On January 31, 2020, the U.K. exited from the EU (BREXIT). Additionally, the results of the U.K.’s BREXIT caused, and may continue to cause, volatility in global stock markets, currency exchange rate fluctuations and global economic uncertainty. Although it is unknown what the terms of the U.K.’s future relationship with the EU will be, it is possible that there will be higher tariffs or greater restrictions on imports and exports between the U.K. and the EU and increased regulatory complexities. The effects of BREXIT will depend on any agreements the U.K. makes to retain access to EU markets either during a transitional period or on a permanent basis. These measures could potentially disrupt our supply chain, including delays of imports and exports, limited access to human capital within some of the target markets and jurisdictions in which we operate and adverse changes to tax benefits or liabilities in these or other jurisdictions. In addition, BREXIT could lead to legal uncertainty and potentially divergent national laws and regulations, including with respect to emissions and similar certifications granted to us by the EU, as the U.K. determines which EU laws to replace or replicate. Any of these effects of BREXIT, among others, could have a material adverse impact on our results of operations, financial condition and cash flows.

Unanticipated changes in our effective tax rate, the adoption of new tax legislation or exposure to additional income tax liabilities could adversely affect our profitability.

We are subject to income taxes in the U.S. and numerous international jurisdictions. Our income tax provision and cash tax liability in the future could be adversely affected by changes in earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities, changes in tax laws and the discovery of new information in the course of our tax return preparation process. The carrying value of deferred tax assets, which are predominantly in the U.S., is dependent on our ability to generate future taxable income in the U.S. We are also subject to ongoing tax audits. These audits can involve complex issues, which may require an extended period of time to resolve and can be highly judgmental. Tax authorities may disagree with certain tax reporting positions taken by us and, as a result, assess additional taxes against us. We regularly assess the likely outcomes of these audits in order to determine the appropriateness of our tax provision. The amounts ultimately paid upon resolution of these or subsequent tax audits could be materially different from the amounts previously included in our income tax provision and, therefore, could have a material impact on our tax provision.

Our global operations are subject to laws and regulations that impose significant compliance costs and create reputational and legal risk.

Due to the international scope of our operations, we are subject to a complex system of commercial and trade regulations around the world. Recent years have seen an increase in the development and enforcement of laws regarding trade compliance and anti-corruption, such as the U.S. Foreign Corrupt Practices Act and similar laws from other countries, as well as new regulatory requirements regarding data privacy, such as the European Union General Data Protection Regulation. Our numerous foreign subsidiaries, affiliates and joint venture partners are governed by laws, rules and business practices that differ from those of the U.S. The activities of these entities may not comply with U.S. laws or business practices or our Code of Business Conduct. Violations of these laws may result in severe criminal or civil sanctions, could disrupt our business and result in an adverse effect on our reputation, business and results of operations, financial condition and cash flows. We cannot predict the nature, scope or effect of future regulatory requirements to which our operations might be subject or the manner in which existing laws might be administered or interpreted.

Our operations are subject to increasingly stringent environmental laws and regulations.

Our plants and operations are subject to increasingly stringent environmental laws and regulations in all of the countries in which we operate, including laws and regulations governing air emission, discharges to water and the generation, handling, storage,

Table of Contents

transportation, treatment and disposal of waste materials. While we believe that we are in compliance in all material respects with these environmental laws and regulations, there can be no assurance that we will not be adversely impacted by costs, liabilities or claims with respect to existing or subsequently acquired operations, under either present laws and regulations or those that may be adopted or imposed in the future. We are also subject to laws requiring the cleanup of contaminated property. If a release of hazardous substances occurs at or from any of our current or former properties or at a landfill or another location where we have disposed of hazardous materials, we may be held liable for the contamination and the amount of such liability could be material.

Future bans or limitations on the use of diesel-powered vehicles or other applications could have a material adverse impact on our business over the long term.

In an effort to limit greenhouse gas emissions and combat climate change, multiple countries and cities have announced that they plan to implement a ban on the use in their countries or cities of diesel-powered products in the near or distant future. These countries include China, India and Germany. In addition, California government officials have called for the state to phase out sales of diesel-powered certain vehicles by 2035. To the extent that these types of bans are actually implemented in the future on a broad basis, or in one or more of our key markets, our diesel business over the long-term could experience material adverse impacts.

BUSINESS CONDITIONS / DISRUPTIONS

We are vulnerable to supply shortages from single-sourced suppliers, including suppliers that may be impacted by the COVID-19 pandemic, and any delay in receiving critical supplies could have a material adverse effect on our results of operations, financial condition and cash flows.

We single source a significant number of parts and raw materials critical to our business operations. Any delay in our suppliers' deliveries may adversely affect our operations at multiple manufacturing locations, forcing us to seek alternative supply sources to avoid serious disruptions. Delays may be caused by factors affecting our suppliers (including the COVID-19 pandemic, capacity constraints, port congestion, labor disputes, economic downturns, availability of credit or impaired financial condition), suppliers' allocations to other purchasers, weather emergencies, natural disasters, acts of government or acts of war or terrorism. In particular, if the COVID-19 pandemic continues and results in extended periods of travel, commercial and other restrictions, we could continue to incur global supply disruptions. Any extended delay in receiving critical supplies could impair our ability to deliver products to our customers and have a material adverse effect on our results of operations, financial condition and cash flows.

A sustained market slowdown due to the impacts from the COVID-19 pandemic, other public health crises, epidemics or pandemics or otherwise, could have a material and adverse effect on our results of operations, financial condition and cash flows.

The COVID-19 pandemic triggered a significant downturn in our markets globally and these challenging market conditions could continue for an extended period of time. Most global economies slowed and there is still much uncertainty as to when these global markets will fully recover. If any or all of these major markets were to endure a sustained slowdown or recession due to the impacts of the COVID-19 pandemic, other public health crises, epidemics or pandemics or otherwise decline, it could have a material adverse effect on our results of operations, financial condition and cash flows.

Our manufacturing and supply chain abilities may be materially and adversely impacted by an extended shutdown or disruption of our operations due to the COVID-19 pandemic which could materially and adversely affect our results of operations, financial condition and cash flows.

The outbreak of COVID-19 spread throughout the world and became a global pandemic with the resultant economic impacts evolving into a worldwide recession. The pandemic triggered a significant downturn in our markets globally, which continued to unfavorably impact market conditions throughout 2020 and these challenging market conditions could continue for an extended period of time. In an effort to contain the spread of COVID-19, maintain the well-being of our employees and stakeholders, match the reduced demand from our customers and in accordance with governmental requirements, we closed or partially shut down certain office, manufacturing, distribution and technical center facilities around the world in March 2020. Although most of our manufacturing, distribution and technical center facilities re-opened early in the second quarter of 2020, some operated at reduced capacities, most of our global office buildings remained closed through the remainder of 2020. Despite many of our markets recovering in the second half of 2020, the ongoing spread of the virus prior to widespread vaccination presents several risks to our business, especially in the first half of 2021. While the impacts of the pandemic and the resulting global recession are expected to be temporary, the duration of the production and supply chain disruptions, and related financial impacts, cannot be estimated at this time. Should the reduced manufacturing and distribution capacities continue for an extended period of time or worsen, the impact on our production and supply chain could have a material adverse effect on our results of operations, financial condition and cash flows.

We face the challenge of accurately aligning our capacity with our demand.

Our markets are cyclical in nature and we face periods when demand fluctuates significantly higher or lower than our normal operating levels, including COVID-19 related shut-downs. Accurately forecasting our expected volumes and appropriately adjusting

Table of Contents

our capacity are important factors in determining our results of operations and cash flows. We manage our capacity by adjusting our manufacturing workforce, capital expenditures and purchases from suppliers. In periods of weak demand we may face under-utilized capacity and un-recovered overhead costs, while in periods of strong demand we may experience unplanned costs and could fail to meet customer demand. We cannot guarantee that we will be able to adequately adjust our manufacturing capacity in response to significant changes in customer demand, which could harm our business. In addition, the COVID-19 pandemic and related reductions in demand forced certain of our customer’s facilities around the world to close or partially shut down operations, inhibiting our ability to forecast demand and caused related closures and partial shut-downs of certain of our manufacturing facilities. If we do not accurately align our manufacturing capabilities with demand it could have a material adverse effect on our results of operations, financial condition and cash flows.

Our truck manufacturers and OEM customers discontinuing outsourcing their engine supply needs, financial distress, particularly related to the COVID-19 pandemic or bankruptcy, or a change-in-control of one of our large truck OEM customers could have a material adverse impact on our results of operations, financial condition and cash flows.

We recognize significant sales of engines and components to a few large on-highway truck OEM customers which have been an integral part of our positive business results for several years. Many are truck manufacturers or OEMs that manufacture engines for some of their own vehicles. Despite their own engine manufacturing abilities, these customers have historically chosen to outsource certain types of engine production to us due to the quality of our engine products, our emission compliance capabilities, our systems integration, their customers' preferences, their desire for cost reductions, their desire for eliminating production risks and their desire to maintain company focus. However, there can be no assurance that these customers will continue to outsource, or outsource as much of, their engine production in the future. In addition, increased levels of OEM vertical integration could result from a number of factors, such as shifts in our customers' business strategies, acquisition by a customer of another engine manufacturer, the inability of third-party suppliers to meet product specifications and the emergence of low-cost production opportunities in foreign countries. Any significant reduction in the level of engine production outsourcing from our truck manufacturer or OEM customers, financial distress of one of our large truck OEM customers due to the COVID-19 pandemic or bankruptcy or a change-in-control, could likely lead to significant reductions in our sales volumes, commercial disputes, receivable collection issues, and other negative consequences that could have a material adverse impact on our results of operations, financial condition and cash flows.

A slowdown in infrastructure development and/or depressed commodity prices could adversely affect our business.

Infrastructure development and strong commodity prices have been significant drivers of our historical growth, but as the pace of investment in infrastructure slowed in recent years (especially in China and Brazil), commodity prices were significantly lower and demand for our products in off-highway markets was weak. Weakness in commodity prices, including any negative impacts on commodity prices such as oil, gas and coal, adversely impacted mining industry participants’ demand for vehicles and equipment that contain our engines and other products over the past several years. Continued deterioration in infrastructure and commodities markets, including the impacts from COVID-19, could adversely affect our customers’ demand for vehicles and equipment and, as a result, could adversely affect our business.

We may fail to realize all of the expected enhanced revenue, earnings and cash flow from our investment in the Eaton Cummins Automated Transmission Technologies joint venture.

A significant component of our investment in the Eaton Cummins Automated Transmission Technologies joint venture related to the expected growth in automated transmission products in North America and China. While we believe we will ultimately achieve these objectives, it is possible that we will be unable to achieve our original expectations within our anticipated time frame or in the anticipated amounts. As part of the purchase accounting associated with the formation of the joint venture, significant goodwill and intangible asset balances were recorded on the consolidated balance sheet. If cash flows from the joint venture fall short of our anticipated amounts, these assets could be subject to non-cash impairment charges, negatively impacting our earnings.

We derive significant earnings from investees that we do not directly control, with more than 50 percent of these earnings from our China-based investees.

For 2020, we recognized $452 million of equity, royalty and interest income from investees, compared to $330 million in 2019. Approximately half of our equity, royalty and interest income from investees is from four of our 50 percent owned joint ventures in China - Beijing Foton Cummins Engine Co., Ltd., Dongfeng Cummins Engine Company, Ltd., Chongqing Cummins Engine Company, Ltd. and Dongfeng Cummins Emission Solutions Co. Ltd. Although a significant percentage of our net income is derived from these unconsolidated entities, we do not unilaterally control their management or their operations, which puts a substantial portion of our net income at risk from the actions or inactions of these entities. A significant reduction in the level of contribution by these entities to our net income would likely have a material adverse effect on our results of operations and cash flows.

PRODUCTS AND TECHNOLOGY

Our products are subject to recall for performance or safety-related issues.

Our products are subject to recall for performance or safety-related issues. Product recalls subject us to reputational risk, loss of current and future customers, reduced revenue and product recall costs. Product recall costs are incurred when we decide, either voluntarily or involuntarily, to recall a product through a formal campaign to solicit the return of specific products due to known or suspected performance or safety issues. Any significant product recalls could have material adverse effects on our results of operations, financial condition and cash flows. See Note 12, "PRODUCT WARRANTY LIABILITY" to the Consolidated Financial Statements for additional information.

The development of new technologies may materially reduce the demand for our current products and services.

We are investing in new products and technologies, including electrified powertrains, hydrogen production and fuel cells, for planned introduction into certain new and existing markets. Given the early stages of development of some of these new products and technologies, there can be no guarantee of the future market acceptance and investment returns with respect to our planned products, which will face competition from an array of other technologies and manufacturers. The increased adoption of electrified powertrains in some market segments could result in lower demand for current diesel or natural gas engines and components and, over time, reduce the demand for related parts and service revenues from diesel or natural gas powertrains. Furthermore, it is possible that we may not be successful in developing segment-leading electrified or alternate fuel powertrains and some of our existing customers could choose to develop their own, or source from other manufacturers, and any of these factors could have a material adverse impact on our results of operations, financial condition and cash flows.

Lower-than-anticipated market acceptance of our new or existing products or services could have a material adverse impact on our results of operations, financial condition and cash flows.

Although we conduct market research before launching new or refreshed engines and introducing new services, many factors both within and outside our control affect the success of new or existing products and services in the marketplace. Offering engines and services that customers desire and value can mitigate the risks of increasing competition and declining demand, but products and services that are perceived to be less than desirable (whether in terms of price, quality, overall value, fuel efficiency or other attributes) can exacerbate these risks. With increased consumer interconnectedness through the internet, social media and other media, mere allegations relating to poor quality, safety, fuel efficiency, corporate responsibility or other key attributes can negatively impact our reputation or market acceptance of our products or services, even if such allegations prove to be inaccurate or unfounded.

Our products are exposed to variability in material and commodity costs.

Our businesses establish prices with our customers in accordance with contractual time frames; however, the timing of material and commodity market price increases may prevent us from passing these additional costs on to our customers through timely pricing actions. Additionally, higher material and commodity costs around the world may offset our efforts to reduce our cost structure. While we customarily enter into financial transactions and contractual pricing adjustment provisions with our customers that attempt to address some of these risks (notably with respect to copper, platinum and palladium), there can be no assurance that commodity price fluctuations will not adversely affect our results of operations and cash flows. In addition, while the use of commodity price hedging instruments and contractual pricing adjustments may provide us with some protection from adverse fluctuations in commodity prices, by utilizing these instruments, we potentially forego the benefits that might result from favorable fluctuations in price. As a result, higher material and commodity costs, as well as hedging these commodity costs during periods of decreasing prices, could result in declining margins.

Our business is exposed to potential product liability claims.

We face an inherent business risk of exposure to product liability claims in the event that our products' failure to perform to specification results, or is alleged to result, in property damage, bodily injury and/or death. At any given time, we are subject to various and multiple product liability claims, any one of which, if decided adversely to us, may have a material adverse effect on our reported results of operation in the period in which our liability with respect to any such claim is recognized. While we maintain insurance coverage with respect to certain product liability claims, we may not be able to obtain such insurance on acceptable terms in the future, if at all, and any such insurance may not provide adequate coverage against product liability claims. In addition, product liability claims can be expensive to defend and can divert the attention of management and other personnel for significant periods of time, regardless of the ultimate outcome. Furthermore, even if we are successful in defending against a claim relating to our products, claims of this nature could cause our customers to lose confidence in our products and us.

GENERAL

The COVID-19 pandemic created disruptions and turmoil in global credit and financial markets and ongoing impacts could have a material adverse effect on our results of operations, financial condition and cash flows.

The COVID-19 pandemic created disruptions and turmoil in the global credit and financial markets and made it more difficult and costly for us to access capital on favorable terms to meet our liquidity needs. The disruptions to the global credit and financial markets could also have material negative impacts on business operations and financial positions of our customers and suppliers, which may negatively impact our orders, sales and supply chain. If the impacts of the COVID-19 pandemic on global credit and financial markets continue, or worsen, it could negatively impact our business, along with the financial condition of our customers and suppliers, and it could have a material adverse impact on our results of operations, financial condition and cash flows.

We may be adversely impacted by work stoppages and other labor matters.

At December 31, 2020, we employed approximately 57,825 persons worldwide. Approximately 20,279 of our employees worldwide were represented by various unions under collective bargaining agreements that expire between 2021 and 2025. While we have no reason to believe that we will be materially impacted by work stoppages or other labor matters, there can be no assurance that future issues with our labor unions will be resolved favorably or that we will not encounter future strikes, work stoppages, or other types of conflicts with labor unions or our employees. Any of these consequences may have an adverse effect on us or may limit our flexibility in dealing with our workforce. In addition, many of our customers and suppliers have unionized work forces. Work stoppages or slowdowns experienced by us, our customers or suppliers, including any work stoppages or slowdowns related to the COVID-19 pandemic, could result in slowdowns or closures that would have a material adverse effect on our results of operations, financial condition and cash flow.

We rely on our executive leadership team and other key personnel as a critical part of our human capital resources.

We depend on the skills, institutional knowledge, working relationships, and continued services and contributions of key personnel, including our executive leadership team as a critical part of our human capital resources. In addition, our ability to achieve our operating and strategic 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 have material adverse effects on our results of operations, financial condition and cash flows.

In particular, our continued success will depend in part on our ability to retain the talents and dedication of key employees. If key employees terminate their employment or become ill as a result of the COVID-19 pandemic or otherwise, 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 employees who leave.

We may be adversely impacted by the effects of climate change and may incur increased costs and experience other impacts due to new or more stringent greenhouse gas regulations designed to address climate change.

The scientific consensus indicates that emissions of greenhouse gases (GHG) continue to alter the composition of Earth’s atmosphere in ways that are affecting, and are expected to continue to affect, the global climate. The potential impacts of climate change on our customers, product offerings, operations, facilities and suppliers are accelerating and uncertain, as they will be particular to local and customer-specific circumstances. These potential impacts may include, among other items, physical long-term changes in freshwater availability and the frequency and severity of weather events as well as customer product changes either through preference or regulation.

Concerns regarding climate change may lead to additional international, national, regional and local legislative and regulatory responses. Various stakeholders, including legislators and regulators, shareholders and non-governmental organizations, are continuing to look for ways to reduce GHG emissions. We could face risks to our brand reputation, investor confidence and market share due to an inability to innovate and develop new products that decrease GHG emissions. Increased input costs, such as fuel and electricity, and compliance-related costs could also impact customer operations and demand for our products. As the impact of any future GHG legislative or regulatory requirements on our global businesses and products is dependent on the timing, scope and design of the mandates or standards, we are currently unable to predict its potential impact which could have a material adverse effect on our results of operations, financial condition and cash flows. The regulation of GHG emissions could also increase our operating costs through higher utility, transportation and materials costs.

Our plan to reposition our portfolio of product offerings through exploration of strategic acquisitions and divestitures may expose us to additional costs and risks.

Part of our strategic plan is to improve our revenue growth, gross margins and earnings by exploring the repositioning of our portfolio of product line offerings through the pursuit of potential strategic acquisitions and/or divestitures to provide future strategic, financial and operational benefits and improve shareholder value. There can be no assurance that we will be able to identify suitable candidates or consummate these transactions on favorable terms. The successful identification and completion of any strategic transaction depends on a number of factors that are not entirely within our control, including the availability of suitable candidates and our ability to negotiate terms acceptable to all parties involved, conclude satisfactory agreements and obtain all necessary regulatory approvals. Accordingly, we may not be able to successfully negotiate and complete specific transactions. The exploration, negotiation and consummation of strategic transactions may involve significant expenditures by us, which may adversely affect our results of operations at the time such expenses are incurred, and may divert management’s attention from our existing business. Strategic transactions also may have adverse effects on our existing business relationships with suppliers and customers.

If required, the financing for strategic acquisitions could result in an increase in our indebtedness, dilute the interests of our shareholders or both. Any acquisition may not be accretive to us for a significant period of time following the completion of such acquisition. Also, our ability to effectively integrate any potential acquisition into our existing business and culture may not be successful, which could jeopardize future financial and operational performance for the combined businesses. In addition, if an acquisition results in any additional goodwill or increase in other intangible assets on our balance sheet and subsequently becomes impaired, we would be required to record a non-cash impairment charge, which could result in a material adverse effect on our financial condition.

Similarly, any strategic divestiture of a product line or business may reduce our revenue and earnings, reduce the diversity of our business, result in substantial costs and expenses and cause disruption to our employees, customers, vendors and communities in which we operate.

Our information technology systems and our products are exposed to potential security breaches or other disruptions which may adversely impact our competitive position, reputation, results of operations, financial condition and cash flows.

We rely on the capacity, reliability and security of our information technology systems and data security infrastructure in connection with various aspects of our business activities. We also rely on our ability to expand and continually update these systems and related infrastructure in response to the changing needs of our business. As we implement new systems, they may not perform as expected. We face the challenge of supporting our older systems and implementing necessary upgrades. In addition, some of these systems are managed by third-party service providers and are not under our direct control. If we experience a problem with an important information technology system, including during system upgrades and/or new system implementations, the resulting disruptions could have an adverse effect on our business and reputation. As customers adopt and rely on cloud-based digital technologies and services we offer, any disruption of the confidentiality, integrity or availability of those services could have an adverse effect on our business and reputation.

The data handled by our information technology systems is vulnerable to security threats. Our operations routinely involve receiving, storing, processing and transmitting sensitive information pertaining to our business, customers, dealers, suppliers, employees and other sensitive matters. While we continually work to safeguard our systems and mitigate potential risks, there is no assurance that these actions will be sufficient to prevent information technology security threats, such as security breaches, computer malware, computer viruses and other "cyber attacks," which are increasing in both frequency and sophistication, along with power outages or hardware failures. These threats could result in unauthorized public disclosures of information, create financial liability, subject us to legal or regulatory sanctions, disrupt our ability to conduct our business, result in the loss of intellectual property or damage our reputation with customers, dealers, suppliers and other stakeholders. As a result of the COVID-19 pandemic and resulting government actions to restrict movement, a large percentage of our salaried employees are working remotely. This remote working environment may pose a heightened risk for security breaches or other disruptions of our information technology systems.

In addition, our products, including our engines, contain interconnected and increasingly complex systems that control various processes and these systems are potentially subject to "cyber attacks" and disruption. The impact of a significant information technology event on either of our information technology systems or our products could have a material adverse effect on our competitive position, reputation, results of operations, financial condition and cash flows.

We are exposed to political, economic and other risks that arise from operating a multinational business.

Our business is subject to the political, economic and other risks that are inherent in operating in numerous countries. These risks include:

•public health crises, including the spread of a contagious disease, such as COVID-19, and other catastrophic events;

Table of Contents

•the difficulty of enforcing agreements and collecting receivables through foreign legal systems;

•trade protection measures and import or export licensing requirements;

•the imposition of taxes on foreign income and tax rates in certain foreign countries that exceed those in the U.S.;

•the imposition of tariffs, exchange controls or other restrictions;

•difficulty in staffing and managing widespread operations and the application of foreign labor regulations;

•required compliance with a variety of foreign laws and regulations; and

•changes in general economic and political conditions in countries where we operate, particularly in emerging markets.

As we continue to operate our business globally, our success will depend, in part, on our ability to anticipate and effectively manage these and other related risks. There can be no assurance that the consequences of these and other factors relating to our multinational operations will not have a material adverse effect upon us.

We face significant competition in the regions we serve.

The markets in which we operate are highly competitive. We compete worldwide with a number of other manufacturers and distributors that produce and sell similar products. We primarily compete with diesel engines and related diesel products; however, new technologies continue to be developed for gasoline, natural gas, electrification and other technologies and we will continue to face new competition from these expanding technologies. Our products primarily compete on the basis of performance, price, total cost of ownership, fuel economy, emissions compliance, speed of delivery, quality and customer support. We also face competitors in some emerging regions who have established local practices and long standing relationships with participants in these markets. There can be no assurance that our products will be able to compete successfully with the products of other companies and in other markets.

Increasing global competition among our customers may affect our existing customer relationships and restrict our ability to benefit from some of our customers' growth.

As our customers in emerging markets continue to grow in size and scope, they are increasingly seeking to export their products to other countries. This has meant greater demand for our advanced engine technologies to help these customers meet the more stringent emissions requirements of developed markets, as well as greater demand for access to our distribution systems for purposes of equipment servicing. As these emerging market customers enter into, and begin to compete in more developed markets, they may increasingly begin to compete with our existing customers in these markets. Our further aid to emerging market customers could adversely affect our relationships with developed market customers. In addition, to the extent the competition does not correspond to overall growth in demand, we may see little or no benefit from this type of expansion by our emerging market customers.

We are subject to foreign currency exchange rate and other related risks.

We conduct operations in many areas of the world involving transactions denominated in a variety of currencies. We are subject to foreign currency exchange rate risk to the extent that our costs are denominated in currencies other than those in which we earn revenues. In addition, since our financial statements are denominated in U.S. dollars, changes in foreign currency exchange rates between the U.S. dollar and other currencies have had, and will continue to have, an impact on our results of operations, financial condition and cash flows. The U.S. dollar strengthened in recent years resulting in material unfavorable impacts on our revenues in those years. If the U.S. dollar continues strengthening against other currencies, we will experience additional volatility in our financial statements.

While we customarily enter into financial transactions that attempt to address these risks and many of our supply agreements with customers include foreign currency exchange rate adjustment provisions, there can be no assurance that foreign currency exchange rate fluctuations will not adversely affect our future results of operations and cash flows. In addition, while the use of currency hedging instruments may provide us with some protection from adverse fluctuations in foreign currency exchange rates, by utilizing these instruments we potentially forego the benefits that might result from favorable fluctuations in foreign currency exchange rates.

We also face risks arising from the imposition of foreign exchange controls and currency devaluations. Foreign exchange controls may limit our ability to convert foreign currencies into U.S. dollars or to remit dividends and other payments by our foreign subsidiaries or businesses located in or conducted within a country imposing controls. Currency devaluations result in a diminished value of funds denominated in the currency of the country instituting the devaluation. See Management's Discussion and Analysis for additional information.

Significant declines in future financial and stock market conditions, particularly those related to the global recession due to the COVID-19 pandemic, could diminish our pension plan asset performance and adversely impact our results of operations, financial condition and cash flow.

We sponsor both funded and unfunded domestic and foreign defined benefit pension and other retirement plans. Our pension cost and the required contributions to our pension plans are directly affected by the value of plan assets, the projected and actual rates of return on plan assets and the actuarial assumptions we use to measure our defined benefit pension plan obligations, including the discount rate at which future projected and accumulated pension obligations are discounted to a present value. We could experience increased pension cost due to a combination of factors, including the decreased investment performance of pension plan assets, decreases in the discount rate and changes in our assumptions relating to the expected return on plan assets.

Significant declines in current and future financial and stock market conditions related to the COVID-19 pandemic could cause material losses in our pension plan assets, which could result in increased pension cost in future years and adversely impact our results of operations, financial condition and cash flow. Depending upon the severity and length of market declines and government regulatory changes, we may be legally obligated to make pension payments in the U.S. and perhaps other countries and these contributions could be material.

We are exposed to risks arising from the price and availability of energy.

The level of demand for our products and services is influenced in multiple ways by the price and availability of energy. High energy costs generally drive greater demand for better fuel economy in almost all countries in which we operate. Some of our engine products have been developed with a primary purpose of offering fuel economy improvements, and if energy costs decrease or increase less than expected, demand for these products may likewise decrease. The relative unavailability of electricity in some emerging market countries also influences demand for our electricity generating products, such as our diesel generators. If these countries add energy capacity by expanding their power grids at a rate equal to or faster than the growth in demand for energy, the demand for our generating products could also decrease or increase less than would otherwise be the case.

In December 2019, the Board authorized the acquisition of up to $2.0 billion of additional common stock upon completion of the 2018 repurchase plan. In October 2018, the Board authorized the acquisition of up to $2.0 billion of additional common stock. During the three months ended December 31, 2020, we repurchased $85 million of common stock under the 2018 authorization, completing this program, and repurchased $6 million of common stock under the 2019 authorization. The dollar value remaining available for future purchases under the 2019 program at December 31, 2020, was $1,994 million.

Our Key Employee Stock Investment Plan allows certain employees, other than officers, to purchase shares of common stock on an installment basis up to an established credit limit. We hold participants’ shares as security for the loans and would, in effect, repurchase shares only if the participant defaulted in repayment of the loan. Shares associated with participants' sales are sold as open-market transactions via a third-party broker as of May 1, 2020.

EXECUTIVE SUMMARY AND FINANCIAL HIGHLIGHTS

Overview

We are a global power leader that designs, manufactures, distributes and services diesel, natural gas, electric and hybrid powertrains and powertrain-related components including filtration, aftertreatment, turbochargers, fuel systems, controls systems, air handling systems, automated transmissions, electric power generation systems, batteries, electrified power systems, hydrogen production and fuel cell products. We sell our products to original equipment manufacturers (OEMs), distributors, dealers and other customers worldwide. We have long-standing relationships with many of the leading manufacturers in the markets we serve, including PACCAR Inc, Navistar International Corporation, Daimler Trucks North America and Stellantis N.V. (Chrysler). We serve our customers through a network of over 500 wholly-owned, joint venture and independent distributor locations and over 9,000 Cummins certified dealer locations with service to approximately 190 countries and territories.

Our reportable operating segments consist of Engine, Distribution, Components, Power Systems and New Power. This reporting structure is organized according to the products and markets each segment serves. The Engine segment produces engines (15 liters and smaller) and associated parts for sale to customers in on-highway and various off-highway markets. Our engines are used in trucks of all sizes, buses and recreational vehicles, as well as in various industrial applications, including construction, agriculture, power generation systems and other off-highway applications. The Distribution segment includes wholly-owned and partially-owned distributorships engaged in wholesaling engines, generator sets and service parts, as well as performing service and repair activities on our products and maintaining relationships with various OEMs throughout the world. The Components segment sells filtration products, aftertreatment systems, turbochargers, electronics, fuel systems and automated transmissions. The Power Systems segment is an integrated power provider, which designs, manufactures and sells engines (16 liters and larger) for industrial applications (including mining, oil and gas, marine and rail), standby and prime power generator sets, alternators and other power components. The New Power segment designs, manufactures, sells and supports hydrogen production solutions as well as electrified power systems ranging from fully electric to hybrid along with innovative components and subsystems, including battery and fuel cell technologies. We continue to serve all our markets as they adopt electrification and alternative power technologies, meeting the needs of our OEM partners and end customers.

Table of Contents

Our financial performance depends, in large part, on varying conditions in the markets we serve, particularly the on-highway, construction and general industrial markets. Demand in these markets tends to fluctuate in response to overall economic conditions. Our sales may also be impacted by OEM inventory levels, production schedules and stoppages. Economic downturns in markets we serve generally result in reduced sales of our products and can result in price reductions in certain products and/or markets. As a worldwide business, our operations are also affected by currency, political, economic, public health crises, epidemics or pandemics and regulatory matters, including adoption and enforcement of environmental and emission standards, in the countries we serve. As part of our growth strategy, we invest in businesses in certain countries that carry high levels of these risks such as China, Brazil, India, Mexico, Russia and countries in the Middle East and Africa. At the same time, our geographic diversity and broad product and service offerings have helped limit the impact from a drop in demand in any one industry or customer or the economy of any single country on our consolidated results.

COVID-19 Update

While the impacts of the pandemic and the resulting global recession are expected to be temporary, the duration of the production and supply chain disruptions, and related financial impacts, cannot be estimated at this time. Should the reduced manufacturing and distribution capacities continue for an extended period of time or worsen, the impact on our production and supply chain could have a material adverse effect on our results of operations, financial condition and cash flows. Our Board of Directors (the Board) continues to monitor and evaluate all of these factors along with the continuing impacts of the COVID-19 pandemic on our business and operations.

2020 Results

A summary of our results is as follows:


	Years ended December 31,
In millions, except per share amounts	2020		2019		2018

Net sales	$	19,811	$	23,571	$	23,771







Net income attributable to Cummins Inc.	1,789		2,260		2,141
Earnings per common share attributable to Cummins Inc.
Basic	$	12.07	$	14.54	$	13.20
Diluted	12.01		14.48		13.15

Worldwide revenues decreased 16 percent in 2020 compared to 2019, as we experienced lower demand in all major operating segments and most geographic regions due to the economic impacts of COVID-19 and the anticipated 2020 down cycle in most of our markets. Net sales in the U.S. and Canada declined by 21 percent primarily due to COVID-19 impacts resulting in decreased demand in the North American on-highway markets, which also negatively impacted our emission solutions, automated transmissions and turbo technologies businesses, reduced sales in all distribution product lines, decreased demand for power generation equipment and lower demand in off-highway markets (especially construction). International demand (excludes the U.S. and Canada) declined by 7 percent compared to 2019, with lower sales in all geographic regions except China. The decrease in international sales was principally due to COVID-19 impacts resulting in lower demand for industrial products (primarily international mining markets), decreased demand for power generation equipment, lower volumes in on-highway markets (mainly medium-duty truck markets), reduced demand in all distribution product lines and unfavorable foreign currency impacts of 2 percent of international sales (primarily the

Brazilian real and Indian rupee), partially offset by higher demand in our emission solutions business in China and India and our electronics and fuel systems business in China.

The following table contains sales and EBITDA (defined as earnings or losses before interest expense, income taxes, depreciation and amortization and noncontrolling interests) by operating segment for the years ended December 31, 2020 and 2019. See Note 22, "OPERATING SEGMENTS," to the Consolidated Financial Statements for additional information and a reconciliation of our segment information to the corresponding amounts in our Consolidated Statements of Net Income.

Net income attributable to Cummins Inc. for 2020 was $1.8 billion, or $12.01 per diluted share, on sales of $19.8 billion, compared to 2019 net income attributable to Cummins Inc. of $2.3 billion, or $14.48 per diluted share, on sales of $23.6 billion. The decrease in net income attributable to Cummins Inc. and earnings per diluted share was driven by lower net sales, decreased gross margin, a higher effective tax rate and unfavorable foreign currency fluctuations (primarily the Brazilian real), partially offset by prior restructuring actions, temporary salary reductions and reduced variable compensation resulting in lower overall compensation expenses, increased equity, royalty and interest income from investees primarily in China (due to stronger demand for construction equipment and trucks) and favorable adjustments related to India Tax Law Changes in March 2020. The decrease in gross margin and gross margin percentage was mainly due to lower volumes, partially offset by prior restructuring actions, temporary salary reductions and lower variable compensation resulting in decreased compensation expenses and lower material costs. Diluted earnings per common share for 2020 benefited $0.24 per share from fewer weighted-average shares outstanding, primarily due to the stock repurchase program.

We generated $2.7 billion of operating cash flows in 2020, compared to $3.2 billion in 2019. See the section titled "Cash Flows" in the "LIQUIDITY AND CAPITAL RESOURCES" section for a discussion of items impacting cash flows.

Our debt to capital ratio (total capital defined as debt plus equity) at December 31, 2020, was 31.7 percent, compared to 21.9 percent at December 31, 2019. The increase was primarily due to a $1,797 million higher total debt balance as the result of our August 2020 debt issuance. At December 31, 2020, we had $3.9 billion in cash and marketable securities on hand and access to our $3.5 billion credit facilities, if necessary, to meet currently anticipated working capital, investment and funding needs.

In the first half of 2020, we entered into additional interest rate lock agreements to reduce the variability of the cash flows of the interest payments on a total of $500 million of fixed rate debt forecast to be issued in 2023 to replace our senior notes at maturity.

In 2020, we repurchased $641 million or 3.9 million shares of common stock. See Note 15, "CUMMINS INC. SHAREHOLDERS' EQUITY" to the Consolidated Financial Statements for additional information.

In June and July of 2020, we settled our February 2014 interest rate swaps, which previously converted our $500 million debt issue, due in 2023, from fixed rate to floating rate based on a LIBOR spread. We will amortize the $24 million gain realized upon settlement over the remaining three-year term of the related debt.

On August 19, 2020, we entered into an amended and restated 364-day credit agreement that allows us to borrow up to $1.5 billion of unsecured funds at any time prior to August 18, 2021. This credit agreement amended and restated the prior $1.5 billion-day credit facility that matured on August 19, 2020.

In October 2020, the Board authorized an increase to our quarterly dividend of 3 percent from $1.311 per share to $1.35 per share.

In 2020, the investment gain on our U.S. pension trust was 8.9 percent while our U.K. pension trust gain was 13.7 percent. Our global pension plans, including our unfunded and non-qualified plans, were 112 percent funded at December 31, 2020. Our U.S. defined benefit plan, which represents approximately 52 percent of the worldwide pension obligation, was 128 percent funded, and our U.K. defined benefit plan was 114 percent funded. We expect to contribute approximately $75 million in cash to our global pension plans in 2021. In addition, we expect our 2021 net periodic pension cost to approximate $78 million. See application of critical accounting estimates within MD&A and Note 13, "PENSIONS AND OTHER POSTRETIREMENT BENEFITS," to the Consolidated Financial Statements, for additional information concerning our pension and other postretirement benefit plans.

On April 29, 2019, we announced that we were conducting a formal internal review of our emissions certification process and compliance with emission standards for our pick-up truck applications, following conversations with the U.S. Environmental Protection Agency and California Air Resources Board regarding certification of our engines in model year 2019 RAM 2500 and 3500 trucks. We voluntarily disclosed our formal internal review to the regulators and to other government agencies, the Department of Justice (DOJ) and the SEC. We fully cooperated with the DOJ’s and the SEC’s information requests and inquiries and, based on recent communications with these agencies, we do not expect further inquiries. Due to the continuing nature of our formal review, our ongoing cooperation with our regulators and the presence of many unknown facts and circumstances, we cannot predict the final outcome of this review and these regulatory processes, and we cannot provide assurance that the matter will not have a materially adverse impact on our results of operations and cash flows. See Note 14, "COMMITMENTS AND CONTINGENCIES," to the Consolidated Financial Statements for additional information.

As of the date of this filing, our credit ratings and outlooks from the credit rating agencies remain unchanged.

2020 vs. 2019

Net Sales

Net sales decreased $3,760 million, primarily driven by the following:

•Engine segment sales decreased 20 percent due to lower volumes in all North American on-highway markets.

•Distribution segment sales decreased 12 percent due to lower demand in all product lines.

•Components segment sales decreased 13 percent largely due to decreased demand in North America and Western Europe, partially offset by higher demand in China.

•Power Systems segment sales decreased 19 percent primarily due to reduced industrial demand in international mining markets and oil and gas markets in China and North America and lower demand in power generation markets in North America, India and Asia Pacific.

•Unfavorable foreign currency impacts of 1 percent of total sales, mainly the Brazilian real and Indian rupee.

Sales to international markets (excluding the U.S. and Canada), based on location of customers, were 42 percent of total net sales in 2020, compared with 38 percent of total net sales in 2019. A more detailed discussion of sales by segment is presented in the "OPERATING SEGMENT RESULTS" section.

Table of Contents

Cost of Sales

The types of expenses included in cost of sales are the following: parts and material consumption, including direct and indirect materials; salaries, wages and benefits; depreciation on production equipment and facilities and amortization of technology intangibles; estimated costs of warranty programs and campaigns; production utilities; production-related purchasing; warehousing, including receiving and inspection; engineering support costs; repairs and maintenance; production and warehousing facility property insurance; rent for production facilities and other production overhead.

Gross Margin

Gross margin decreased $1,086 million and 0.7 points as a percentage of sales. The decrease in gross margin and gross margin as a percentage of sales were mainly due to lower volumes, partially offset by prior restructuring actions, temporary salary reductions and lower variable compensation resulting in decreased compensation expenses and lower material costs. The provision for warranties issued as a percentage of sales, was 2.2 percent in 2020 and 1.9 percent in 2019. A more detailed discussion of margin by segment is presented in the "OPERATING SEGMENT RESULTS" section.

Selling, General and Administrative Expenses

Selling, general and administrative expenses decreased $329 million, primarily due to prior restructuring actions, temporary salary reductions and lower variable compensation resulting in decreased compensation expenses and reduced travel expenses. Overall, selling, general and administrative expenses, as a percentage of sales, increased to 10.7 percent in 2020 from 10.4 percent in 2019. The increase in selling, general and administrative expenses as a percentage of sales was primarily due to sales declining faster than selling, general and administrative expenses, despite lower compensation expenses.

Research, Development and Engineering Expenses

Research, development and engineering expenses decreased $95 million, primarily due to prior restructuring actions, temporary salary reductions and lower variable compensation resulting in decreased compensation expenses and reduced consulting expenses. Overall, research, development and engineering expenses, as a percentage of sales, increased to 4.6 percent in 2020 from 4.2 percent in 2019, primarily due to sales declining faster than research, development and engineering expenses decreased, despite lower compensation expenses. Research activities continue to focus on development of new products to meet future emission standards around the world, improvements in fuel economy performance of diesel and natural gas-powered engines and related components as well as development activities around fully electric, hybrid and hydrogen powertrain solutions.

Equity, Royalty and Interest Income From Investees

Equity, royalty and interest income from investees increased $122 million, primarily due to higher earnings at Beijing Foton Cummins Engine Co., Ltd., a $37 million favorable adjustment as the result of tax changes within India's 2020-2021 Union Budget of India (India Tax Law Changes) passed in March 2020 and $18 million of technology fee revenue recorded in the first quarter of 2020. See NOTE 4, "INCOME TAXES" to the Consolidated Financial Statements for additional information on India Tax Law Changes.

Restructuring Actions

In the fourth quarter of 2019, we began executing restructuring actions, primarily in the form of voluntary and involuntary employee separation programs. To the extent these programs involved voluntary separations, a liability was recorded at the time offers to employees were accepted. To the extent these programs provided separation benefits in accordance with pre-existing agreements or policies, a liability was recorded once the amount was probable and reasonably estimable. We incurred a charge of $119 million ($90 million after-tax) in the fourth quarter of 2019 for these actions which impacted approximately 2,300 employees. The voluntary actions were completed by December 31, 2019 and the involuntary actions were completed by June 28, 2020. See Note 21, "RESTRUCTURING ACTIONS," to the Consolidated Financial Statements, for additional information.

Income Tax Expense

Our effective tax rate for 2020 was 22.5 percent compared to 20.0 percent for 2019.

The year ended December 31, 2020, contained $26 million, or $0.17 per share, of unfavorable net discrete tax items, primarily due to $33 million of unfavorable changes in tax reserves and $10 million of withholding tax adjustments, partially offset by $15 million of favorable changes due to the India Tax Law Change. The India Tax Law Change eliminated the dividend distribution tax and replaced it with a lower rate withholding tax as the burden shifted from the dividend payor to the dividend recipient for a net favorable income statement impact of $35 million. See NOTE 4, "INCOME TAXES" to the Consolidated Financial Statements for additional information on India Tax Law Changes.

The year ended December 31, 2019, contained $34 million of favorable net discrete tax items, primarily due to withholding taxes and provision to return adjustments.

The change in effective tax rate for the year ended December 31, 2020, versus year ended December 31, 2019, was primarily due to a $60 million swing from favorable to unfavorable net discrete tax items.

Our effective tax rate for 2021 is expected to approximate 22.5 percent, excluding any discrete items that may arise.

Net Income Attributable to Noncontrolling Interests

Noncontrolling interests eliminate the income or loss attributable to non-Cummins ownership interests in our consolidated entities. Noncontrolling interests in income of consolidated subsidiaries increased $14 million principally due to a $19 million unfavorable adjustment as the result of India Tax Law Changes passed in March 2020. See NOTE 4, "INCOME TAXES" to the Consolidated Financial Statements for additional information on India Tax Law Changes.

Net Income Attributable to Cummins Inc. and Diluted Earnings Per Common Share Attributable to Cummins Inc.

Net income and diluted earnings per share attributable to Cummins Inc. decreased $471 million and $2.47 per share, respectively, primarily due to lower net sales, decreased gross margin, a higher effective tax rate and unfavorable foreign currency fluctuations (primarily the Brazilian real), partially offset by prior restructuring actions, temporary salary reductions and reduced variable compensation resulting in lower overall compensation expenses, increased equity, royalty and interest income from investees primarily in China (due to stronger demand for construction equipment and trucks) and favorable adjustments related to India Tax Law Changes in March 2020. Diluted earnings per common share for 2020 benefited $0.24 per share from fewer weighted-average shares outstanding, primarily due to the stock repurchase program.

OPERATING SEGMENT RESULTS

Our reportable operating segments consist of the Engine, Distribution, Components, Power Systems and New Power segments. This reporting structure is organized according to the products and markets each segment serves. We use segment EBITDA as the primary basis for the Chief Operating Decision Maker to evaluate the performance of each of our reportable operating segments. We believe EBITDA is a useful measure of our operating performance as it assists investors and debt holders in comparing our performance on a consistent basis without regard to financing methods, capital structure, income taxes or depreciation and amortization methods, which can vary significantly depending upon many factors. Segment amounts exclude certain expenses not specifically identifiable to segments. See Note 22, "OPERATING SEGMENTS," to the Consolidated Financial Statements for additional information and a reconciliation of our segment information to the corresponding amounts in our Consolidated Statements of Net Income.

Following is a discussion of results for each of our operating segments.

For all prior year segment results comparisons to 2018 see the Results of Operations section of our 2019 Form 10-K.

2020 vs. 2019

Sales

Engine segment sales decreased $2,034 million across all markets. The following were the primary drivers by market:

•Heavy-duty truck engine sales decreased $907 million principally due to lower volumes in North America with lower shipments of 35 percent, partially offset by stronger demand in China.

•Medium-duty truck and bus sales decreased $641 million mainly due to lower demand in North America with decreased shipments of 30 percent.

•Light-duty automotive sales decreased $257 million primarily due to lower pick-up sales in North America with decreased shipments of 16 percent.

•Off-highway sales decreased $229 million principally due to lower demand in construction markets in North America, Western Europe and Asia Pacific, partially offset by higher construction demand in China.

•Unfavorable foreign currency fluctuations, primarily in the Brazilian real.

Total on-highway-related sales for 2020 were 78 percent of total engine segment sales, compared to 80 percent in 2019.

Segment EBITDA

Engine segment EBITDA decreased $219 million, primarily due to lower gross margin, partially offset by increased equity, royalty and interest income from investees, lower selling, general and administrative expenses and decreased research, development and engineering expenses. Gross margin and gross margin as a percentage of sales decreased mainly due to lower volumes, partially offset by prior restructuring actions, temporary salary reductions and lower variable compensation resulting in lower compensation expenses and decreased material costs. Selling, general and administrative expenses decreased principally due to prior restructuring actions, temporary salary reductions and lower variable compensation resulting in decreased compensation expenses, reduced consulting expenses and lower travel expenses. Research, development and engineering expenses decreased principally due to prior restructuring actions, temporary salary reductions and lower variable compensation resulting in decreased compensation expenses and reduced consulting expenses. Equity, royalty and interest income from investees increased largely due to higher earnings at Beijing Foton Cummins Engine Co., Ltd. and increased earnings at Tata Cummins Ltd., mainly due to an $18 million favorable adjustment related to India Tax Law Changes passed in March 2020 and $18 million of technology fee revenue recorded in the first quarter of 2020. See NOTE 4, "INCOME TAXES" to the Consolidated Financial Statements for additional information on India Tax Law Changes.

2021 OUTLOOK

COVID-19 Impacts

The COVID-19 pandemic negatively impacted our financial performance in 2020 and may continue to do so in the future. Because the magnitude and duration of the pandemic and its economic consequences are unclear, the pandemic’s impact on our performance is difficult to predict.

COVID-19 Positive Trends

COVID-19 vaccines are currently being administered around the world with the hope that the majority of the population will have access to the vaccine by the middle of 2021. If the distribution and the effectiveness of the vaccine are consistent with current government and health organization estimates we anticipate the vaccine will mitigate the spread of the virus by the end of 2021 and allow a return to more normal operations in the second half of the year.

COVID-19 Challenges

The ongoing spread of the virus and increase in infections prior to widespread vaccination presents several risks to our business, especially in the first half of 2021. The three principle areas where COVID-19 may negatively impact our financial performance are through its impact on customer demand, the impact on our ability to procure parts from suppliers and our ability to operate our manufacturing and distribution facilities.

Customer Demand – The majority of our major customers, including PACCAR, Navistar, Daimler and Chrysler experienced extended production shutdowns in response to the pandemic in the first half of 2020. Although many of these customers reopened their facilities and ramped up their production in the second half of 2020, levels of future production remain uncertain and will be determined by supply chain constraints, market demand and government decisions to keep economies open.

Supply Chain Impact – Supplier shutdowns may result in parts shortages and negatively impact our ability to manufacture products and meet aftermarket demand. In addition, industry parts shortages may impact the timing of when customer facilities reopen and the speed at which customers ramp up production, negatively impacting demand for our products. Lower demand increases the risk that certain suppliers will face financial issues, potentially impacting their ability to supply parts.

Operations Impact - Our manufacturing and distribution locations are generally considered critical services and the majority of our facilities remain open to meet customer demand. In an effort to contain the spread of COVID-19, maintain the well-being of our employees, ensure compliance with governmental requirements or respond to declines in demand from customers, we closed or partially shut down certain office, manufacturing and distribution facilities around the world at the end of the first quarter and into the third quarter of 2020. We have taken, and will continue to take, a variety of steps to reduce the risk of employees contracting COVID-19 at work. These steps include social distancing, expanded cleaning and sanitization, adjusting work hours and temperature checks. All manufacturing and distribution facilities are now open, but remain subject to future closure if deemed necessary for the safety of our employees or to comply with future government mandates.

Business Outlook Considering Potential COVID-19 Impacts

Our outlook reflects the following positive trends and challenges to our business that could impact our revenue and earnings potential in 2021. Specific impacts of the COVID-19 pandemic are highlighted in the above section but are reflected in our market outlook.

Positive Trends

•We expect demand for pick-up trucks in North America to remain strong and in line with the second half of 2020.

•North American medium-duty and heavy-duty truck demand improved in the fourth quarter and could continue to strengthen above second half of 2020 levels.

•Market demand for trucks in India is expected to improve from 2020 levels.

•We anticipate our aftermarket business will strengthen from second half of 2020 levels, driven primarily by increased truck utilization in North America.

•Our liquidity of $7.0 billion in cash, marketable securities and available credit facilities puts us in a strong position to deal with any uncertainties that may arise in 2021.

Challenges

•Market demand in truck and construction markets in China is expected to decline from record levels in 2020.

•We may close or restructure additional manufacturing and distribution facilities as we evaluate the appropriate size and structure of our manufacturing and distribution capacity, which could result in additional charges.

•Uncertainty in the U.K. surrounding its ability to negotiate trade agreements as a sovereign country could have material negative impacts on our European operations in the long-term.

LIQUIDITY AND CAPITAL RESOURCES

Key Working Capital and Balance Sheet Data

We fund our working capital with cash from operations and short-term borrowings, including commercial paper, when necessary. Various assets and liabilities, including short-term debt, can fluctuate significantly from month to month depending on short-term liquidity needs. As a result, working capital is a prime focus of management's attention. Working capital and balance sheet measures are provided in the following table:


Dollars in millions	December 31, 2020			December 31, 2019
Working capital (1)	$	5,562		$	3,127

Cash Flows

Cash and cash equivalents were impacted as follows:


	Years ended December 31,						Change
In millions	2020		2019		2018		2020 vs. 2019		2019 vs. 2018

Net increase (decrease) in cash and cash equivalents	$	2,272	$	(174)	$	(66)	$	2,446	$	(108)

2020 vs. 2019

Net cash provided by operating activities decreased $459 million, primarily due to lower consolidated net income of $457 million, higher restructuring payments of $106 million, increased equity in income of investees, net of dividends of $91 million and lower other liabilities of $51 million, partially offset by lower working capital requirements of $396 million. During 2020, lower working capital requirements resulted in a cash inflow of $365 million compared to a cash outflow of $31 million in 2019, mainly due to higher accounts payable and accrued expenses, partially offset by a decrease in inventory and higher accounts and notes receivable.

Net cash used in investing activities decreased $431 million, primarily due to the prior year acquisition of Hydrogenics for $235 million, lower capital expenditures of $172 million and higher cash flows from derivatives not designated as hedges of $48 million, partially offset by higher investments in and advances to equity investees of $31 million.

Net cash provided by financing activities increased $2,375 million, principally due to the issuance of $2 billion of long-term debt and lower repurchases of common stock of $630 million, partially offset by higher net payments of commercial paper of $217 million.

The effect of exchange rate changes on cash and cash equivalents decreased $99 million, primarily due to favorable fluctuations in the British pound of $73 million.

Sources of Liquidity

We generate significant ongoing cash flow. Cash provided by operations is our principal source of liquidity with $2.7 billion provided in 2020. At December 31, 2020, our sources of liquidity included:


	December 31, 2020
In millions	Total		U.S.		International		Primary location of international balances
Cash and cash equivalents	$	3,401	$	1,914	$	1,487	China, Singapore, Mexico, Belgium, Australia, Canada

Marketable securities (1)	461		86		375		India
Total	$	3,862	$	2,000	$	1,862
Available credit capacity
Revolving credit facilities (2)	$	3,177
International and other uncommitted domestic credit facilities	$	256

(1) The majority of marketable securities could be liquidated into cash within a few days.
(2) The five-year credit facility for $2.0 billion and the 364-day credit facility for $1.5 billion, maturing August 2023 and August 2021, respectively, are maintained primarily to provide backup liquidity for our commercial paper borrowings and general corporate purposes. At December 31, 2020, we had $323 million of commercial paper outstanding, which effectively reduced the available capacity under our revolving credit facilities to $3.2 billion.

Cash, Cash Equivalents and Marketable Securities

A significant portion of our cash flows are generated outside the U.S. We manage our worldwide cash requirements considering available funds among the many subsidiaries through which we conduct our business and the cost effectiveness with which those funds can be accessed. As a result, we do not anticipate any local liquidity restrictions to preclude us from funding our operating needs with local resources.

If we distribute our foreign cash balances to the U.S. or to other foreign subsidiaries, we could be required to accrue and pay withholding taxes, for example, if we repatriated cash from certain foreign subsidiaries whose earnings we have asserted are permanently reinvested outside of the U.S. Foreign earnings for which we assert permanent reinvestment outside the U.S. consist primarily of earnings of our China, India and Netherlands domiciled subsidiaries. At present, we do not foresee a need to repatriate any earnings from these subsidiaries for which we have asserted permanent reinvestment. However, to help fund cash needs of the U.S. or other international subsidiaries as they arise, we repatriate available cash from certain foreign subsidiaries whose earnings are not permanently reinvested when it is cost effective to do so.

Debt Facilities and Other Sources of Liquidity

On April 14, 2020, we were approved for the Federal Reserve Bank of New York’s Commercial Paper Funding Facility (CPFF) program to assure access to the commercial paper funding markets during volatile credit market conditions. The CPFF was intended to provide a liquidity backstop to U.S. issuers of commercial paper through a special purpose vehicle (SPV). The facility allows us, based on our current short-term credit rating, to issue three-month unsecured commercial paper at a rate equal to a + 110 basis point spread over the three-month overnight index swap rate on the date of issuance. The maximum amount of commercial paper that we may issue at any time through this program is $1.5 billion less the total principal amount of all other outstanding commercial paper that we have issued. We retain full access to our Board authorized $3.5 billion commercial paper program, as reduced by any amounts issued under this facility. The SPV is currently scheduled to cease purchasing commercial paper on March 17, 2021. At December 31, 2020, there were no outstanding borrowings under the CPFF program.

On August 19, 2020, we entered into an amended and restated 364-day credit agreement that allows us to borrow up to $1.5 billion of unsecured funds at any time prior to August 18, 2021. This credit agreement amended and restated the prior $1.5 billion 364-day credit facility that matured on August 19, 2020.

Table of Contents

We have access to committed credit facilities that total $3.5 billion, including the new $1.5 billion 364-day facility that expires August 18, 2021 and our $2.0 billion five-year facility that expires on August 22, 2023. We maintain credit facilities at the current or higher aggregate amounts by renewing or replacing these facilities at or before expiration. These revolving credit facilities are maintained primarily to provide backup liquidity for our commercial paper borrowings and for general corporate purposes. Both credit agreements include a financial covenant requiring that the leverage ratio of net debt of the company and its subsidiaries to the consolidated total capital of the company and its subsidiaries may not exceed 0.65 to 1.0. At December 31, 2020, our leverage ratio was 0.07 to 1.0.

We can issue up to $3.5 billion of unsecured, short-term promissory notes (commercial paper) pursuant to the Board authorized commercial paper programs. The programs facilitate the private placement of unsecured short-term debt through third-party brokers. We intend to use the net proceeds from the commercial paper borrowings for general corporate purposes. At December 31, 2020, we had $323 million of commercial paper outstanding, which effectively reduced the available capacity under our revolving credit facilities to $3.2 billion. The total combined borrowing capacity under the revolving credit facilities and commercial paper programs should not exceed $3.5 billion. See Note 11, "DEBT," to our Consolidated Financial Statements for additional information.

As a well-known seasoned issuer, we filed an automatic shelf registration for an undetermined amount of debt and equity securities with the SEC on February 13, 2019. Under this shelf registration we may offer, from time to time, debt securities, common stock, preferred and preference stock, depositary shares, warrants, stock purchase contracts and stock purchase units.

In July 2017, the U.K.'s Financial Conduct Authority, which regulates the London Interbank Offered Rate (LIBOR), announced it intends to phase out LIBOR by the end of 2021. The cessation date for submission and publication of rates for certain tenors of LIBOR has since been extended until mid-2023. Various central bank committees and working groups continue to discuss replacement of benchmark rates, the process for amending existing LIBOR-based contracts and the potential economic impacts of different alternatives. The Alternative Reference Rates Committee has identified the Secured Overnight Financing Rate (SOFR) as its preferred alternative rate for USD LIBOR. SOFR is a measure of the cost of borrowing cash overnight, collateralized by U.S. Treasury securities, and is based on directly observable U.S. Treasury-backed repurchase transactions. We are evaluating the potential impact of the replacement of the LIBOR benchmark interest rate including risk management, internal operational readiness and monitoring the Financial Accounting Standards Board standard-setting process to address financial reporting issues that might arise in connection with transition from LIBOR to a new benchmark rate. While we do not believe the change will impact us significantly, we continue to evaluate contracts throughout the company. In anticipation of LIBOR's phase out, our revolving credit agreements include a transition mechanism for selecting a benchmark replacement rate for LIBOR, with such benchmark replacement rate to be subject to our agreement.

Supply Chain Financing

We currently have supply chain financing programs with financial intermediaries, which provide certain vendors the option to be paid by financial intermediaries earlier than the due date on the applicable invoice. When a vendor utilizes the program and receives an early payment from a financial intermediary, they take a discount on the invoice. We then pay the financial intermediary the face amount of the invoice on the regularly scheduled due date. We do not reimburse vendors for any costs they incur for participation in the program and their participation is completely voluntary. As a result, all amounts owed to the financial intermediaries are presented as "Accounts payable" in our Consolidated Balance Sheets.

(1) The remaining authorized capacity under these plans was calculated based on the cost to purchase the shares but excludes commission expenses in accordance with the authorized plan.
(2) The shares purchased under the 2019 repurchase program rounded to zero.

We temporarily suspended share repurchases after the purchases made in the first quarter of 2020 to conserve cash, but resumed repurchasing shares in the fourth quarter of 2020. We may repurchase outstanding shares from time to time during 2021 to enhance shareholder value and to offset the dilutive impact of employee stock-based compensation plans.

Dividends

Total dividends paid to common shareholders in 2020, 2019 and 2018 were $782 million, $761 million and $718 million, respectively. Declaration and payment of dividends in the future depends upon our income and liquidity position, among other factors, and is subject to declaration by the Board, who meets quarterly to consider our dividend payment. We expect to fund dividend payments with cash from operations.

In October 2020, the Board authorized an increase to our quarterly dividend of 3 percent from $1.311 per share to $1.35 per share. Cash dividends per share paid to common shareholders and the Board authorized increases for the last three years were as follows:


	Quarterly Dividends
	2020		2019		2018
First quarter	$	1.311	$	1.14	$	1.08
Second quarter	1.311		1.14		1.08

Capital Expenditures

Capital expenditures, including spending on internal use software, were $575 million, $775 million and $784 million in 2020, 2019 and 2018, respectively. We continue to invest in new product lines and targeted capacity expansions. We plan to spend an estimated $725 million to $775 million in 2021 on capital expenditures, excluding internal use software, with over 50 percent of these expenditures expected to be invested in North America. In addition, we plan to spend an estimated $60 million to $70 million on internal use software in 2021.

Pensions

Our global pension plans, including our unfunded and non-qualified plans, were 112 percent funded at December 31, 2020. Our U.S. defined benefit plan, which represents approximately 52 percent of the worldwide pension obligation, was 128 percent funded, and our U.K. defined benefit plan was 114 percent funded. The funded status of our pension plans is dependent upon a variety of variables and assumptions including return on invested assets, market interest rates and levels of voluntary contributions to the plans. In 2020, the investment gain on our U.S. pension trust was 8.9 percent while our U.K. pension trust gain was 13.7 percent. Approximately 72 percent of our pension plan assets are held in highly liquid investments such as fixed income and equity securities. The remaining 28 percent of our plan assets are held in less liquid, but market valued investments, including real estate, private equity, venture capital, opportunistic credit and insurance contracts.

We sponsor funded and unfunded domestic and foreign defined benefit pension plans. Contributions to the U.S. and U.K. plans were as follows:


	Years ended December 31,
In millions		2020		2019		2018



Defined benefit pension contributions		$	92	$	121	$	37



Defined contribution pension plans		85		102		104

We anticipate making total contributions of approximately $75 million to our global defined benefit pension plans in 2021. Expected contributions to our defined benefit pension plans in 2021 will meet or exceed the current funding requirements.

Current Maturities of Short and Long-Term Debt

We had $323 million of commercial paper outstanding at December 31, 2020, that matures in less than one year. The maturity schedule of our existing long-term debt does not require significant cash outflows until 2023 when our 3.65% senior notes are due. Required annual long-term debt principal payments range from $23 million to $526 million over the next five years. See Note 11, "DEBT," to the Consolidated Financial Statements for additional information.

Restructuring Actions

In the fourth quarter of 2019, we began executing restructuring actions, primarily in the form of voluntary and involuntary employee separation programs. We incurred a charge of $119 million ($90 million after-tax) in the fourth quarter of 2019 for these actions which impacted approximately 2,300 employees. Restructuring payments were substantially complete at September 27, 2020. See Note 21, "RESTRUCTURING ACTIONS," to the Consolidated Financial Statements, for additional information.

Management's Assessment of Liquidity

Despite the global recession and volatility in the capital markets due to the pandemic, our financial condition and liquidity remain strong. Our solid balance sheet and credit ratings enable us to have ready access to credit and the capital markets. We assess our liquidity in terms of our ability to generate adequate cash to fund our operating, investing and financing activities. We believe our existing cash and marketable securities, operating cash flow and revolving credit facilities provide us with the financial flexibility needed to fund working capital, common stock repurchases, acquisitions, targeted capital expenditures, dividend payments, projected pension obligations and debt service obligations through 2021 and beyond. We continue to generate significant cash from operations and maintain access to our expanded revolving credit facilities and commercial paper programs as noted above.

The contractual obligations reported above exclude our unrecognized tax benefits of $122 million as of December 31, 2020. We are not able to reasonably estimate the period in which cash outflows relating to uncertain tax contingencies could occur. See Note 4, "INCOME TAXES," to the Consolidated Financial Statements for additional information.

APPLICATION OF CRITICAL ACCOUNTING ESTIMATES

A summary of our significant accounting policies is included in Note 1, "SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES," of our Consolidated Financial Statements which discusses accounting policies that we have selected from acceptable alternatives.

Our Consolidated Financial Statements are prepared in accordance with generally accepted accounting principles in the U.S. which often requires management to make judgments, estimates and assumptions regarding uncertainties that affect the reported amounts presented and disclosed in the financial statements. Management reviews these estimates and assumptions based on historical experience, changes in business conditions, including the impacts of COVID-19, and other relevant factors they believe to be reasonable under the circumstances. In any given reporting period, our actual results may differ from the estimates and assumptions used in preparing our Consolidated Financial Statements.

Critical accounting estimates are defined as follows: the estimate requires management to make assumptions about matters that were highly uncertain at the time the estimate was made; different estimates reasonably could have been used; or if changes in the estimate are reasonably likely to occur from period to period and the change would have a material impact on our financial condition or results of operations. Our senior management has discussed the development and selection of our accounting policies, related accounting estimates and the disclosures set forth below with the Audit Committee of the Board. We believe our critical accounting estimates include estimating liabilities for warranty programs, assessing goodwill impairments, accounting for income taxes and pension benefits.

Warranty Programs

We estimate and record a liability for base warranty programs at the time our products are sold. Our estimates are based on historical experience and reflect management's best estimates of expected costs at the time products are sold and subsequent adjustment to those expected costs when actual costs differ. As a result of the uncertainty surrounding the nature and frequency of product recall programs, the liability for such programs is recorded when we commit to a recall action or when a recall becomes probable and estimable, which generally occurs when management internally approves or commits to the action. Our warranty liability is generally affected by component failure rates, repair costs and the point of failure within the product life cycle. Future events and circumstances related to these factors could materially change our estimates and require adjustments to our liability. New product launches require a greater use of judgment in developing estimates until historical experience becomes available. Product specific experience is typically available four or five quarters after product launch, with a clear experience trend evident eight quarters after launch. We generally record warranty expense for new products upon shipment using a preceding product's warranty history and a multiplicative factor based upon preceding similar product experience and new product assessment until sufficient new product data is available for warranty estimation. We then use a blend of actual new product experience and preceding product historical experience for several subsequent

Table of Contents

quarters, and new product specific experience thereafter. Note 12, "PRODUCT WARRANTY LIABILITY," to our Consolidated Financial Statements contains a summary of the activity in our warranty liability account for 2020, 2019 and 2018 including adjustments to pre-existing warranties.

Goodwill Impairment

We are required to make certain subjective and complex judgments in assessing whether a goodwill impairment event has occurred, including assumptions and estimates used to determine the fair value of our reporting units. We test for goodwill impairment at the reporting unit level and our reporting units are the operating segments or the components of operating segments that constitute businesses for which discrete financial information is available and is regularly reviewed by management.

•Macroeconomic conditions, such as a deterioration in general economic conditions, including COVID-19 impacts, fluctuations in foreign exchange rates and/or other developments in equity and credit markets;

•Industry and market considerations, such as a deterioration in the environment in which an entity operates, material loss in market share and significant declines in product pricing;

•Cost factors, such as an increase in raw materials, labor or other costs;

•Overall financial performance, such as negative or declining cash flows or a decline in actual or forecasted revenue;

•Other relevant entity-specific events, such as material changes in management or key personnel and

•Events affecting a reporting unit, such as a change in the composition or carrying amount of its net assets including acquisitions and dispositions.

The examples noted above are not all-inclusive, and we consider other relevant events and circumstances that affect the fair value of a reporting unit in determining whether to perform the quantitative goodwill impairment test.

Our goodwill recoverability assessment is based on our annual strategic planning process. This process includes an extensive review of expectations for the long-term growth of our businesses and forecasted future cash flows. In order to determine the valuation of our reporting units, we use either the market approach or the income approach using a discounted cash flow model. Our income approach method uses a discounted cash flow model in which cash flows anticipated over several periods, plus a terminal value at the end of that time horizon, are discounted to their present value using an appropriate rate of return. Our estimates are based upon our historical experience, our current knowledge from our commercial relationships and available external information about future trends.

The discounted cash flow model requires us to make projections of revenue, gross margin, operating expenses, working capital investment and fixed asset additions for the reporting units over a multi-year period. Additionally, management must estimate a weighted-average cost of capital, which reflects a market rate, for each reporting unit for use as a discount rate. The discounted cash flows are compared to the carrying value of the reporting unit and, if less than the carrying value, the difference is recorded as a goodwill impairment loss. In addition, we also perform a sensitivity analysis to determine how much our forecasts can fluctuate before the fair value of a reporting unit would be lower than its carrying amount. We perform the required procedures as of the end of our fiscal third quarter.

While none of our reporting units recorded a goodwill impairment in 2020, we determined the automated transmission business is our only reporting unit with material goodwill where the estimated fair value does not substantially exceed the carrying value. The estimated fair value of the reporting unit exceeds its carrying amount of $1.1 billion by approximately 18 percent. Total goodwill in this reporting unit is $544 million. Since this reporting unit is made up of only one business, our joint venture with Eaton Corporation plc (Eaton Cummins Automated Transmission Technologies), acquired in 2017, we did not expect the estimated fair value would exceed the carrying value by a significant amount. We valued this reporting unit primarily using an income approach based on its expected future cash flows. The critical assumptions that factored into the valuation are the projected future revenues and EBITDA margins of the business as well as the discount rate used to present value these future cash flows. A 100 basis point increase in the discount rate would result in a 16 percent decline in the fair value of the reporting unit.

Table of Contents

Accounting for Income Taxes

We determine our income tax expense using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax effects of temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Future tax benefits of net operating loss and credit carryforwards are also recognized as deferred tax assets. We evaluate the recoverability of our deferred tax assets each quarter by assessing the likelihood of future profitability and available tax planning strategies that could be implemented to realize our net deferred tax assets. At December 31, 2020, we recorded net deferred tax assets of $154 million. The assets included $382 million for the value of net operating loss and credit carryforwards. A valuation allowance of $346 million was recorded to reduce the tax assets to the net value management believed was more likely than not to be realized. In the event our operating performance deteriorates, future assessments could conclude that a larger valuation allowance will be needed to further reduce the deferred tax assets.

In addition, we operate within multiple taxing jurisdictions and are subject to tax audits in these jurisdictions. These audits can involve complex issues, which may require an extended period of time to resolve. We accrue for the estimated additional tax and interest that may result from tax authorities disputing uncertain tax positions. We believe we made adequate provisions for income taxes for all years that are subject to audit based upon the latest information available. A more complete description of our income taxes and the future benefits of our net operating loss and credit carryforwards is disclosed in Note 4, "INCOME TAXES," to our Consolidated Financial Statements.

Pension Benefits

We sponsor a number of pension plans globally, with the majority of assets in the U.S. and the U.K. In the U.S. and the U.K., we have several major defined benefit plans that are separately funded. We account for our pension programs in accordance with employers' accounting for defined benefit pension plans, which requires that amounts recognized in financial statements be determined using an actuarial basis. As a result, our pension benefit programs are based on a number of statistical and judgmental assumptions that attempt to anticipate future events and are used in calculating the expense and liability related to our plans each year at December 31. These assumptions include discount rates used to value liabilities, assumed rates of return on plan assets, future compensation increases, employee turnover rates, actuarial assumptions relating to retirement age, mortality rates and participant withdrawals. The actuarial assumptions we use may differ significantly from actual results due to changing economic conditions, participant life span and withdrawal rates. These differences may result in a material impact to the amount of net periodic pension cost to be recorded in our Consolidated Financial Statements in the future.

The expected long-term return on plan assets is used in calculating the net periodic pension cost. We considered several factors in developing our expected rate of return on plan assets. The long-term rate of return considers historical returns and expected returns on current and projected asset allocations. Projected returns are based primarily on broad, publicly traded passive fixed income and equity indices and forward-looking estimates of the value added by active investment management. At December 31, 2020, based upon our target asset allocations, it is anticipated that our U.S. investment policy will generate an average annual return over the 30-year projection period equal to or in excess of 6.25 percent, including the additional positive returns expected from active investment management.

The one-year return for our U.S. plans was 8.9 percent for 2020. Our U.S. plan assets averaged annualized returns of 9.12 percent over the prior ten years and resulted in approximately $443 million of actuarial gains in accumulated other comprehensive loss (AOCL) in the same period. Based on the historical returns and forward-looking return expectations as plan assets continue to be de-risked, consistent with our investment policy, we believe continuing our investment return assumption of 6.25 percent per year in 2021 for U.S. pension assets is reasonable.

The methodology used to determine the rate of return on pension plan assets in the U.K. was based on establishing an equity-risk premium over current long-term bond yields adjusted based on target asset allocations. At December 31, 2020, based upon our target asset allocations, it is anticipated that our U.K. investment policy will generate an average annual return over the 20-year projection period equal to or in excess of 4 percent. The one-year return for our U.K. plans was 13.7 percent for 2020. We generated average annualized returns of 9.20 percent over ten years, resulting in approximately $724 million of actuarial gains in AOCL. Our strategy with respect to our investments in pension plan assets is to be invested with a long-term outlook. Based on the historical returns and forward-looking return expectations as the plan assets continue to be de-risked, we believe continuing our investment return

Table of Contents

assumption of 4.0 percent in 2021 for U.K. pension assets is reasonable. Our pension plan asset allocations at December 31, 2020 and 2019 and target allocation for 2021 are as follows:

The differences between the actual return on plan assets and expected long-term return on plan assets are recognized in the asset value used to calculate net periodic cost over five years. The table below sets forth the expected return assumptions used to develop our pension cost for the period 2018-2020 and our expected rate of return for 2021.


	Long-term Expected Return Assumptions
	2021		2020		2019		2018
U.S. plans	6.25	%	6.25	%	6.25	%	6.50	%
U.K. plans	4.00	%	4.00	%	4.00	%	4.00	%

Pension accounting offers various acceptable alternatives to account for the differences that eventually arise between the estimates used in the actuarial valuations and the actual results. It is acceptable to delay or immediately recognize these differences. Under the delayed recognition alternative, changes in pension obligations (including those resulting from plan amendments) and changes in the value of assets set aside to meet those obligations are not recognized in net periodic pension cost as they occur but are recognized initially in AOCL and subsequently amortized as components of net periodic pension cost systematically and gradually over future periods. In addition to this approach, we may also adopt immediate recognition of actuarial gains or losses. Immediate recognition introduces volatility in financial results. We have chosen to delay recognition and amortize actuarial differences over future periods. If we adopted the immediate recognition approach, we would record a loss of $989 million ($772 million after-tax) from cumulative actuarial net losses for our U.S. and U.K. pension plans.

The difference between the expected return and the actual return on plan assets is deferred from recognition in our results of operations and under certain circumstances, such as when the difference exceeds 10 percent of the greater of the market value of plan assets or the projected benefit obligation, the difference is amortized over future years of service. This is also true of changes to actuarial assumptions. Under the delayed recognition alternative, the actuarial gains and losses are recognized and recorded in AOCL. At December 31, 2020, we had net pension actuarial losses of $714 million and $250 million for the U.S. and U.K. pension plans, respectively. As these amounts exceed 10 percent of their respective plan assets, the excess is amortized over the average remaining service lives of participating employees. Net actuarial losses decreased our shareholders' equity by $63 million after-tax in 2020. The loss is primarily due to lower discount rates in the U.S. and U.K, partially offset by strong asset returns in the U.S. and U.K.

The table below sets forth the net periodic pension cost for the years ended December 31 and our expected cost for 2021.


In millions	2021		2020		2019		2018
Net periodic pension cost	$	78	$	102	$	65	$	86

We expect 2021 net periodic pension cost to decrease compared to 2020, primarily due to favorable actuarial experience and investment returns, partially offset by lower discount rates in the U.S. and U.K. The increase in net periodic pension cost in 2020 compared to 2019 was primarily due to lower discount rates in the U.S. and U.K. The decrease in net periodic pension cost in 2019 compared to 2018 was due to higher discount rates and favorable actuarial experience in the U.S. and U.K., partially offset by a lower expected rate of return in the U.S.

The weighted-average discount rates used to develop our net periodic pension cost are set forth in the table below.


	Discount Rates
	2021		2020		2019		2018
U.S. plans	2.62	%	3.36	%	4.36	%	3.66	%
U.K. plans	1.50	%	2.00	%	2.80	%	2.55	%

The discount rate enables us to state expected future cash payments for benefits as a present value on the measurement date. The guidelines for setting this rate suggest the use of a high-quality corporate bond rate. We used bond information provided by Moody's Investor Services, Inc. and Standard & Poor's Rating Services. All bonds used to develop our hypothetical portfolio in the U.S. and U.K. were deemed high-quality, non-callable bonds (Aa or better) at December 31, 2020, by at least one of the bond rating agencies.

Our model called for projected payments until near extinction for the U.S. and the U.K. For both countries, our model matches the present value of the plan's projected benefit payments to the market value of the theoretical settlement bond portfolio. A single equivalent discount rate is determined to align the present value of the required cash flow with the value of the bond portfolio. The resulting discount rate is reflective of both the current interest rate environment and the plan's distinct liability characteristics.

The table below sets forth the estimated impact on our 2021 net periodic pension cost relative to a change in the discount rate and a change in the expected rate of return on plan assets.


In millions	Impact on Pension Cost Increase/(Decrease)
Discount rate used to value liabilities
0.25 percent increase	$	(19)
0.25 percent decrease	19
Expected rate of return on assets
1 percent increase	(53)
1 percent decrease	53

The above sensitivities reflect the impact of changing one assumption at a time. A higher discount rate decreases the plan obligations and decreases our net periodic pension cost. A lower discount rate increases the plan obligations and increases our net periodic pension cost. It should be noted that economic factors and conditions often affect multiple assumptions simultaneously and the effects of changes in key assumptions are not necessarily linear. Note 13, "PENSIONS AND OTHER POSTRETIREMENT BENEFITS," to our Consolidated Financial Statements provides a summary of our pension benefit plan activity, the funded status of our plans and the amounts recognized in our Consolidated Financial Statements.

ITEM 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to financial risk resulting from volatility in foreign exchange rates, interest rates and commodity prices. This risk is closely monitored and managed through the use of financial derivative instruments including foreign currency forward contracts, interest rate swaps, commodity swap contracts, zero-cost collars and physical forward contracts. These instruments, as further described below, are accounted for as cash flow or fair value hedges or as economic hedges not designated as hedges for accounting purposes. Financial derivatives are used expressly for hedging purposes and under no circumstances are they used for speculative purposes. When material, we adjust the estimated fair value of our derivative contracts for counterparty or our credit risk. None of our derivative instruments are subject to collateral requirements. Substantially all of our derivative contracts are subject to master netting arrangements, which provide us with the option to settle certain contracts on a net basis when they settle on the same day with the same currency. In addition, these arrangements provide for a net settlement of all contracts with a given counterparty in the event that the arrangement is terminated due to the occurrence of default or a termination event.

We also enter into physical forward contracts with certain suppliers to purchase minimum volumes of commodities at contractually stated prices for various periods. These arrangements, as further described below, enable us to fix the prices of portions of our normal purchases of these commodities, which otherwise are subject to market volatility.

The following describes our risk exposures and provides the results of a sensitivity analysis performed at December 31, 2020. The sensitivity analysis assumes instantaneous, parallel shifts in foreign currency exchange rates and commodity prices.

Table of Contents

Foreign Exchange Rate Risk

As a result of our international business presence, we are exposed to foreign currency exchange rate risks. We transact business in foreign currencies and, as a result, our income experiences some volatility related to movements in foreign currency exchange rates. To help manage our exposure to exchange rate volatility, we use foreign currency forward contracts on a regular basis to hedge forecasted intercompany and third-party sales and purchases denominated in non-functional currencies. Our foreign currency cash flow hedges generally mature within two years. These foreign currency forward contracts are designated and qualify as foreign currency cash flow hedges. For the years ended December 31, 2020 and 2019, there were no circumstances that resulted in the discontinuance of a foreign currency cash flow hedge.

To minimize the income volatility resulting from the remeasurement of net monetary assets and payables denominated in a currency other than the functional currency, we enter into foreign currency forward contracts, which are considered economic hedges. The objective is to offset the gain or loss from remeasurement with the gain or loss from the fair market valuation of the forward contract. These derivative instruments are not designated as hedges.

At December 31, 2020, the potential gain or loss in the fair value of our outstanding foreign currency contracts, assuming a hypothetical 10 percent fluctuation in the currencies of such contracts, would be approximately $10 million. The sensitivity analysis of the effects of changes in foreign currency exchange rates assumes the notional value to remain constant for the next 12 months. The analysis ignores the impact of foreign exchange movements on our competitive position and potential changes in sales levels. Any change in the value of the contracts, real or hypothetical, would be significantly offset by an inverse change in the value of the underlying hedged items.

Interest Rate Risk

Commodity Price Risk

We are exposed to fluctuations in commodity prices due to contractual agreements with component suppliers. In order to protect ourselves against future price volatility and, consequently, fluctuations in gross margins, we periodically enter into commodity swap, forward and zero-cost collar contracts with designated banks and other counterparties to fix the cost of certain raw material purchases with the objective of minimizing changes in inventory cost due to market price fluctuations. Commencing in 2019, these commodity swaps are designated and qualify as cash flow hedges. At December 31, 2020, realized and unrealized gains and losses related to these hedges were not material to our financial statements. The physical forward contracts qualify for the normal purchases scope exceptions and are treated as purchase commitments. The commodity zero-cost collar contracts that represent an economic hedge, but are not designated for hedge accounting, are marked to market through earnings.

At December 31, 2020, the potential gain or loss related to the outstanding commodity zero-cost collar contracts, assuming a hypothetical 10 percent fluctuation in the price of such commodities, would be approximately $1 million. The sensitivity analysis of the effects of changes in commodity prices assumes the notional value to remain constant for the next 12 months. The analysis ignores the impact of commodity price movements on our competitive position and potential changes in sales levels. Any change in the value of the zero-cost collar contracts, real or hypothetical, would be significantly offset by an inverse change in the value of the underlying hedged items.

We also limit our exposure to commodity price risk by entering into purchasing arrangements to fix the price of certain volumes of platinum and palladium expected to be used in our products. We enter into physical forward contracts with suppliers of platinum and palladium to purchase some volumes of the commodities at contractually stated prices for various periods, generally less than two years. These arrangements enable us to fix the prices of a portion of our purchases of these commodities, which otherwise are subject to market volatility.

MANAGEMENT'S REPORT TO SHAREHOLDERS

Management's Report on Financial Statements and Practices

The accompanying Consolidated Financial Statements of Cummins Inc. were prepared by management, which is responsible for their integrity and objectivity. The statements were prepared in accordance with generally accepted accounting principles and include amounts that are based on management's best judgments and estimates. The other financial information included in the annual report is consistent with that in the financial statements.

Management also recognizes its responsibility for conducting our 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 the host countries in which we operate, within the Foreign Corrupt Practices Act and potentially conflicting interests of its employees. We maintain a systematic program to assess compliance with these policies.

To comply with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, we designed and implemented a structured and comprehensive compliance process to evaluate our internal control over financial reporting across the enterprise.

Management's Report on Internal Control Over Financial Reporting

The management of Cummins Inc. is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and preparation of our Consolidated Financial Statements for external purposes in accordance with accounting principles generally accepted in the United States of America.

Management assessed the effectiveness of our internal control over financial reporting and concluded it was effective as of December 31, 2020. In making its assessment, management utilized the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (2013).

The effectiveness of our internal control over financial reporting as of December 31, 2020, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Cummins Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Cummins Inc. and its subsidiaries (the “Company”) as of December 31, 2020 and 2019, and the related consolidated statements of net income, comprehensive income, changes in equity, and cash flows for each of the three years in the period ended December 31, 2020, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Change in Accounting Principle

As discussed in Note 1 to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, 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 opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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 audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated 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 consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) provide reasonable assurance regarding

Table of Contents

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.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters 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 matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Goodwill Impairment Assessment - Automated Transmission Reporting Unit

As described in Notes 1 and 9 to the consolidated financial statements, the Company’s consolidated goodwill balance was $1,293 million, and the goodwill associated with the Automated Transmission reporting unit was $544 million as of December 31, 2020. Management performs an impairment test as of the end of the fiscal third quarter each year, or more frequently if events or circumstances indicate the fair value of a reporting unit is less than its carrying amount. Management performs the annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying value. Management’s valuation method is an income approach using a discounted cash flow model. The discounted cash flow model requires projections of revenue, gross margin, operating expenses, working capital investment and fixed asset additions for the Automated Transmission reporting unit over a multi-year period, and a discount rate based upon a weighted-average cost of capital.

The principal considerations for our determination that performing procedures relating to the goodwill impairment assessment for the Automated Transmission reporting unit is a critical audit matter are (i) the significant judgment by management when developing the fair value measurement of the reporting unit; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and in evaluating audit evidence relating to management’s cash flow projections and significant assumptions related to projected revenue, projected gross margin, and the discount rate; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s goodwill impairment assessment, including controls over the valuation of the Automated Transmission reporting unit. These procedures also included, among others, testing management’s process for developing the fair value estimate. This included evaluating the appropriateness of the discounted cash flow model, testing the completeness, accuracy, and relevance of underlying data used in the model, and evaluating the reasonableness of significant assumptions used by management related to projected revenue, projected gross margin, and the discount rate. Evaluating management assumptions related to projected revenue and projected gross margin involved evaluating whether the assumptions used by management were reasonable considering (i) the current and past performance of the Automated Transmission reporting unit, and (ii) the consistency with external market and industry data. Professionals with specialized skill and knowledge were used to assist in the evaluation of the appropriateness of the Company’s discounted cash flow model and reasonableness of the discount rate assumption.

Base Product Warranty

As described in Notes 1 and 12 to the consolidated financial statements, management estimates and records a liability for base product warranty programs at the time products are sold. As of December 31, 2020, the accrued liability for base product warranty programs was $1,346 million. As disclosed by management, the estimate for one of the base product warranty programs is based on historical experience and reflects management's best estimates of expected costs at the time products are sold and subsequent adjustment to those expected costs when actual costs differ. Management’s estimate of base product warranty liability is generally affected by component failure rates, repair costs, and the point of failure within the product life cycle.

The principal considerations for our determination that performing procedures relating to the base product warranty liability is a critical audit matter are (i) the significant judgment by management when determining the estimate for the base product warranty liability; and (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures to evaluate management’s

Table of Contents

estimate and significant assumptions related to component failure rates, repair costs, and the point of failure within the product life cycle.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements.

Procedures related to management’s estimate included evaluating the appropriateness of the method used by management, the completeness, accuracy, and relevance of underlying data used in the warranty estimate, and the reasonableness of significant assumptions used by management in estimating the base product warranty liability related to the component failure rates, repair costs, and the point of failure within the product life cycle. Evaluating management’s assumptions relating to the component failure rates, repair costs, and the point of failure within the product life cycle involved evaluating whether the assumptions were reasonable considering historical product experience of the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

COVID-19

Principles of Consolidation

Our Consolidated Financial Statements are prepared in accordance with generally accepted accounting principles in the United States of America (GAAP). All intercompany balances and transactions are eliminated in consolidation.

We include the accounts of all wholly-owned and majority-owned domestic and foreign subsidiaries where our ownership is more than 50 percent of outstanding equity interests except for majority-owned subsidiaries that are considered variable interest entities (VIEs) where we are not deemed to have a controlling financial interest. In addition, we also consolidate, regardless of our ownership percentage, VIEs or joint ventures for which we are deemed to have a controlling financial interest. We have variable interests in several businesses accounted for under the equity method of accounting, however most of these VIEs are unconsolidated.

For consolidated entities where our ownership interest is less than 100 percent, the noncontrolling ownership interests are reported in our Consolidated Balance Sheets. The noncontrolling ownership interest in our income, net of tax, is classified as "Net income attributable to noncontrolling interests" in our Consolidated Statements of Net Income.

Reclassifications

Certain amounts for 2019 and 2018 have been reclassified to conform to the current year presentation.

Investments in Equity Investees

We use the equity method to account for our investments in joint ventures, affiliated companies and alliances in which we have the ability to exercise significant influence, generally represented by equity ownership or partnership equity of at least 20 percent but not more than 50 percent. Generally, under the equity method, original investments in these entities are recorded at cost and subsequently adjusted by our share of equity in income or losses after the date of acquisition. Investment amounts in excess of our share of an investee's net assets are amortized over the life of the related asset creating the excess, except goodwill which is not amortized. Equity in income or losses of each investee is recorded according to our level of ownership; if losses accumulate, we record our share of losses until our investment has been fully depleted. If our investment has been fully depleted, we recognize additional losses only when we are the primary funding source. We eliminate (to the extent of our ownership percentage) in our Consolidated Financial Statements the profit in inventory held by our equity method investees that has not yet been sold to a third-party. Dividends received from equity method investees reduce the amount of our investment when received and do not impact our earnings. Our investments are classified as "Investments and advances related to equity method investees" in our Consolidated Balance Sheets. Our share of the results from joint ventures, affiliated companies and alliances is reported in our Consolidated Statements of Net Income as "Equity, royalty and interest income from investees," and is reported net of all applicable income taxes.

Table of Contents

Our foreign equity investees are presented net of applicable foreign income taxes in our Consolidated Statements of Net Income. Our remaining U.S. equity investees are partnerships (non-taxable), thus there is no difference between gross or net of tax presentation as the investees are not taxed. See Note 3, "INVESTMENTS IN EQUITY INVESTEES," for additional information.

Use of Estimates in the Preparation of the Financial Statements

Preparation of financial statements requires management to make estimates and assumptions that affect reported amounts presented and disclosed in our Consolidated Financial Statements. Significant estimates and assumptions in these Consolidated Financial Statements require the exercise of judgement and are used for, but not limited to, estimates of future cash flows and other assumptions associated with goodwill and long-lived asset impairment tests, useful lives for depreciation and amortization, warranty programs, determination of discount rate and other assumptions for pensions and other postretirement benefit costs, restructuring costs, income taxes, deferred tax valuation allowances and contingencies and allowances for doubtful accounts. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be different from these estimates.

The global market downturn, closures and limitations on movement related to COVID-19 are expected to be temporary, however, the duration of the production and supply chain disruptions, and related financial impacts, cannot be estimated at this time. This uncertainty could have an impact on certain estimates used in the preparation of our 2020 financial results.

Revenue From Contracts with Customers

Revenue Recognition Sales of Products

We sell to customers either through long-term arrangements or standalone purchase orders. Our long-term arrangements generally do not include committed volumes until underlying purchase orders are issued. Our performance obligations vary by contract, but may include diesel and natural gas engines and engine-related component products, including filtration, aftertreatment, turbochargers, fuel systems, controls systems, air handling systems, automated transmissions, electric power generation systems and construction related projects, batteries, electrified power systems, hydrogen production and fuel cell products, parts, maintenance services and extended warranty coverage.

Typically, we recognize revenue on the products we sell at a point in time, generally in accordance with shipping terms, which reflects the transfer of control to the customer. Since control of construction projects transfer to the customer as the work is performed, revenue on these projects is recognized based on the percentage of inputs incurred to date compared to the total expected cost of inputs, which is reflective of the value transferred to the customer. Revenue is recognized under long-term maintenance and other service agreements over the term of the agreement as underlying services are performed based on the percentage of the cost of services provided to date compared to the total expected cost of services to be provided under the contract. Sales of extended coverage are recognized based on the pattern of expected costs over the extended coverage period or, if such a pattern is unknown, on a straight-line basis over the coverage period as the customer is considered to benefit from our stand ready obligation over the coverage period. In all cases, we believe cost incurred is the most representative depiction of the extent of service performed to date on a particular contract.

Our arrangements may include the act of shipping products to our customers after the performance obligation related to that product has been satisfied. We have elected to account for shipping and handling as activities to fulfill the promise to transfer goods and have not allocated revenue to the shipping activity. All related shipping and handling costs are accrued at the time the related performance obligation has been satisfied.

Our sales arrangements may include the collection of sales and other similar taxes that are then remitted to the related taxing authority. We have elected to present the amounts collected for these taxes net of the related tax expense rather than presenting them as additional revenue.

We grant credit limits and terms to customers based upon traditional practices and competitive conditions. Typical terms vary by market, but payments are generally due in 90 days or less from invoicing for most of our product and service sales, while payments on construction and other similar arrangements may be due on an installment basis.

For contracts where the time between cash collection and performance is less than one year, we have elected to use the practical expedient that allows us to ignore the possible existence of a significant financing component within the contract. For contracts where this time period exceeds one year, generally the timing difference is the result of business concerns other than financing. We do have a limited amount of customer financing for which we charge or impute interest, but such amounts are immaterial to our Consolidated Statements of Net Income.

Sales Incentives

We provide various sales incentives to both our distribution network and OEM customers. These programs are designed to promote the sale of our products in the channel or encourage the usage of our products by OEM customers. When there is uncertainty

Table of Contents

surrounding these sales incentives, we may limit the amount of revenue we recognize under a contract until the uncertainty has been resolved. Sales incentives primarily fall into three categories:

•Volume rebates;

•Market share rebates; and

•Aftermarket rebates.

For volume rebates, we provide certain customers with rebate opportunities for attaining specified volumes during a particular quarter or year. We consider the expected amount of these rebates at the time of the original sale as we determine the overall transaction price. We update our assessment of the amount of rebates that will be earned quarterly based on our best estimate of the volume levels the customer will reach during the measurement period. For market share rebates, we provide certain customers with rebate opportunities based on the percentage of their production that utilizes our product. These rebates are typically measured either quarterly or annually and we assess them at least quarterly to determine our current estimates of amounts expected to be earned. These estimates are considered in the determination of transaction price at the time of the original sale based on the current market shares, with adjustments made as the level changes. For aftermarket rebates, we provide incentives to promote sales to certain dealers and end-markets. These rebates are typically paid on a quarterly, or more frequent basis. At the time of the sales, we consider the expected amount of these rebates when determining the overall transaction price. Estimates are adjusted at the end of each quarter based on the amounts yet to be paid. These estimates are based on historical experience with the particular program.

Sales Returns

The initial determination of the transaction price may also be impacted by expected product returns. Rights of return do not exist for the majority of our sales other than for quality issues. We do offer certain return rights in our aftermarket business, where some aftermarket customers are permitted to return small amounts of parts and filters each year, and in our power generation business, which sells portable generators to retail customers. An estimate of future returns is accounted for at the time of sale as a reduction in the overall contract transaction price based on historical return rates.

Multiple Performance Obligations

Our sales arrangements may include multiple performance obligations. We identify each of the material performance obligations in these arrangements and allocate the total transaction price to each performance obligation based on its relative selling price. In most cases, the individual performance obligations are also sold separately and we use that price as the basis for allocating revenue to the included performance obligations. When an arrangement includes multiple performance obligations and invoicing to the customer does not match the allocated portion of the transaction price, unbilled revenue or deferred revenue is recorded reflecting that difference. Unbilled and deferred revenue are discussed in more detail below.

Long-term Contracts

Our long-term maintenance agreements often include a variable component of the transaction price. We are generally compensated under such arrangements on a cost per hour of usage basis. We typically can estimate the expected usage over the life of the contract, but reassess the transaction price each quarter and adjust our recognized revenue accordingly. Certain maintenance agreements apply to generators used to provide standby power, which have limited expectations of usage. These agreements may include monthly minimum payments, providing some certainty to the total transaction price. For these particular contracts that relate to standby power, we limit revenue recognized to date to an amount representing the total minimums earned to date under the contract plus any cumulative billings earned in excess of the minimums. We reassess the estimates of progress and transaction price on a quarterly basis. For prime power arrangements, revenue is not subject to such a constraint and is generally equal to the current estimate on a percentage of completion basis times the total expected revenue under the contract.

Deferred Revenue

The timing of our billing does not always match the timing of our revenue recognition. We record deferred revenue when we are entitled to bill a customer in advance of when we are permitted to recognize revenue. Deferred revenue may arise in construction contracts, where billings may occur in advance of performance or in accordance with specific milestones. Deferred revenue may also occur in long-term maintenance contracts, where billings are often based on usage of the underlying equipment, which generally follows a predictable pattern that often will result in the accumulation of collections in advance of our performance of the related maintenance services. Finally, deferred revenue exists in our extended coverage contracts, where the cash is collected prior to the commencement of the coverage period. Deferred revenue is included in our Consolidated Balance Sheets as a component of current liabilities for the amount expected to be recognized in revenue in a period of less than one year and long-term liabilities for the amount expected to be recognized as revenue in a period beyond one year. Deferred revenue is recognized as revenue when control of the underlying product, project or service passes to the customer under the related contract.

Table of Contents

Unbilled Revenue

We recognize unbilled revenue when the revenue has been earned, but not yet billed. Unbilled revenue is included in our Consolidated Balance Sheets as a component of current assets for those expected to be collected in a period of less than one year and long-term assets for those expected to be collected in a period beyond one year. Unbilled revenue relates to our right to consideration for our completed performance under a contract. Unbilled revenue generally arises from contractual provisions that delay a portion of the billings on genset deliveries until commissioning occurs. Unbilled revenue may also occur when billings trail the provision of service in construction and long-term maintenance contracts. Our unbilled revenue is assessed for collection risks at the time the amounts are initially recorded. This estimate of expected losses reflects those losses expected to occur over the contractual life of the unbilled amount through the time of collection. We did not record any impairment losses on our unbilled revenues during the years ended December 31, 2020, 2019 and 2018.

Contract Costs

We are required to record an asset for the incremental costs of obtaining a contract with a customer and other costs to fulfill a contract not otherwise required to be immediately expensed when we expect to recover those costs. The only material incremental cost we incur is commission expense, which is generally incurred in the same period as the underlying revenue. Costs to fulfill a contract are generally limited to customer-specific engineering expenses that do not meet the definition of research and development expenses. As a practical expedient, we have elected to recognize these costs of obtaining a contract as an expense when the related contract period is less than one year. When the period exceeds one year, this asset is amortized over the life of the contract. We did not have any material capitalized balances at December 31, 2020 or 2019.

Extended Warranty

We sell extended warranty coverage on most of our engines and on certain components. We consider a warranty to be extended coverage in any of the following situations:

•When a warranty is sold separately or is optional (extended coverage contracts, for example) or

•When a warranty provides additional services.

The consideration collected is initially deferred and is recognized as revenue in proportion to the costs expected to be incurred in performing services over the contract period. We compare the remaining deferred revenue balance quarterly to the estimated amount of future claims under extended warranty programs and provide an additional accrual when the deferred revenue balance is less than expected future costs.

Foreign Currency Transactions and Translation

We translate assets and liabilities of foreign entities to U.S. dollars, where the local currency is the functional currency, at month-end exchange rates. We translate income and expenses to U.S. dollars using weighted-average exchange rates. We record adjustments resulting from translation in a separate component of accumulated other comprehensive loss (AOCL) and include the adjustments in net income only upon sale, loss of controlling financial interest or liquidation of the underlying foreign investment.

Foreign currency transaction gains and losses are included in current net income. For foreign entities where the U.S. dollar is the functional currency, including those operating in highly inflationary economies when applicable, we remeasure non-monetary balances and the related income statement amounts using historical exchange rates. We include the resulting gains and losses in income, including the effect of derivatives in our Consolidated Statements of Net Income, which combined with transaction gains and losses amounted to a net gain of $4 million and $28 million and a net loss of $34 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Fair Value Measurements

A three-level valuation hierarchy, based upon the observable and unobservable inputs, is used for fair value measurements. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions based on the best evidence available. These two types of inputs create the following fair value hierarchy:

•Level 1 - Quoted prices for identical instruments in active markets;

•Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations whose significant inputs are observable; and

•Level 3 - Instruments whose significant inputs are unobservable.

Table of Contents

Derivative Instruments

We make use of derivative instruments in foreign exchange, commodity price and interest rate hedging programs. Derivatives currently in use are foreign currency forward contracts, commodity swap and physical forward contracts, commodity zero-cost collars and interest rate swaps. These contracts are used strictly for hedging and not for speculative purposes.

We are exposed to market risk from fluctuations in interest rates. We manage our exposure to interest rate fluctuations through the use of interest rate swaps. The objective of the swaps is to more effectively balance our borrowing costs and interest rate risk. The gain or loss on these derivative instruments as well as the offsetting gain or loss on the hedged item are recognized in current income as "Interest expense." For more detail on our interest rate swaps, see Note 11, "DEBT."

Due to our international business presence, we are exposed to foreign currency exchange risk. We transact in foreign currencies and have assets and liabilities denominated in foreign currencies. Consequently, our income experiences some volatility related to movements in foreign currency exchange rates. In order to benefit from global diversification and after considering naturally offsetting currency positions, we enter into foreign currency forward contracts to minimize our existing exposures (recognized assets and liabilities) and hedge forecasted transactions. Foreign currency forward contracts are designated and qualify as foreign currency cash flow hedges. The unrealized gain or loss on the forward contract is deferred and reported as a component of AOCL. When the hedged forecasted transaction (sale or purchase) occurs, the unrealized gain or loss is reclassified into income in the same line item associated with the hedged transaction in the same period or periods during which the hedged transaction affects income. At December 31, 2020 and 2019, realized and unrealized gains and losses related to these hedges were not material to our financial statements.

We are exposed to fluctuations in commodity prices due to contractual agreements with component suppliers. In order to protect ourselves against future price volatility and, consequently, fluctuations in gross margins, we periodically enter into commodity swap, forward and zero-cost collar contracts with designated banks and other counterparties to fix the cost of certain raw material purchases with the objective of minimizing changes in inventory cost due to market price fluctuations. Commencing in 2019, these commodity swaps are designated and qualify as cash flow hedges. At December 31, 2020, realized and unrealized gains and losses related to these hedges were not material to our financial statements. The physical forward contracts qualify for the normal purchases scope exceptions and are treated as purchase commitments. Additional information on the physical forwards is included in Note 14, "COMMITMENTS AND CONTINGENCIES." The commodity zero-cost collar contracts that represent an economic hedge, but are not designated for hedge accounting, are marked to market through earnings.

We record all derivatives at fair value in our financial statements. Cash flows related to derivatives that are designated as hedges are included in the Cash Flows From Operating Activities, while cash flows related to derivatives, that are not designated as hedges, are included in Cash Flows From Investing Activities in our Consolidated Statements of Cash Flows.

Substantially all of our derivative contracts are subject to master netting arrangements, which provide us with the option to settle certain contracts on a net basis when they settle on the same day with the same currency. In addition, these arrangements provide for a net settlement of all contracts with a given counterparty in the event that the arrangement is terminated due to the occurrence of default or a termination event. When material, we adjust the value of our derivative contracts for counter-party or our credit risk. None of our derivative instruments are subject to collateral requirements.

Income Tax Accounting

We determine our income tax expense using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax effects of temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Future tax benefits of net operating loss and credit carryforwards are also recognized as deferred tax assets. We evaluate the recoverability of our deferred tax assets each quarter by assessing the likelihood of future profitability and available tax planning strategies that could be implemented to realize our net deferred tax assets. A valuation allowance is recorded to reduce the tax assets to the net value management believes is more likely than not to be realized. In the event our operating performance deteriorates, future assessments could conclude that a larger valuation allowance will be needed to further reduce the deferred tax assets. In addition, we operate within multiple taxing jurisdictions and are subject to tax audits in these jurisdictions. These audits can involve complex issues, which may require an extended period of time to resolve. We accrue for the estimated additional tax and interest that may result from tax authorities disputing uncertain tax positions. We believe we made adequate provisions for income taxes for all years that are subject to audit based upon the latest information available. A more complete description of our income taxes and the future benefits of our net operating loss and credit carryforwards is disclosed in Note 4, "INCOME TAXES."

Table of Contents

Cash and Cash Equivalents

Cash equivalents are defined as short-term, highly liquid investments with an original maturity of 90 days or less at the time of purchase. The carrying amounts reflected in our Consolidated Balance Sheets for cash and cash equivalents approximate fair value due to the short-term maturity of these investments.

Cash payments for income taxes and interest were as follows:


	Years ended December 31,
In millions	2020		2019		2018








Cash payments for income taxes, net of refunds	$	432	$	691	$	699
Cash payments for interest, net of capitalized interest	88		109		114

Marketable Securities

Debt securities are classified as "held-to-maturity," "available-for-sale" or "trading." We determine the appropriate classification of debt securities at the time of purchase and re-evaluate such classifications at each balance sheet date. At December 31, 2020 and 2019, all of our debt securities were classified as available-for-sale. Debt and equity securities are carried at fair value with the unrealized gain or loss, net of tax, reported in other comprehensive income and other income, respectively. For debt securities, unrealized losses considered to be "other-than-temporary" are recognized currently in other income. The cost of securities sold is based on the specific identification method. The fair value of most investment securities is determined by currently available market prices. Where quoted market prices are not available, we use the market price of similar types of securities that are traded in the market to estimate fair value. See Note 5, "MARKETABLE SECURITIES," for a detailed description of our investments in marketable securities.

Accounts Receivable and Allowance for Doubtful Accounts

Trade accounts receivable represent amounts billed to customers and not yet collected or amounts that have been earned, but may not be billed until the passage of time, and are recorded when the right to consideration becomes unconditional. Trade accounts receivable are recorded at the invoiced amount, which approximates net realizable value, and generally do not bear interest. The allowance for doubtful accounts is our best estimate of the amount of expected credit losses in our existing accounts receivable. We determine the allowance based on our historical collection experience and by performing an analysis of our accounts receivable in light of the current economic environment. This estimate of expected losses reflects those losses expected to occur over the contractual life of the receivable. We review our allowance for doubtful accounts on a regular basis. In addition, when necessary, we provide an allowance for the full amount of specific accounts deemed to be uncollectible. Account balances are charged off against the allowance in the period in which we determine that it is probable the receivable will not be recovered. The allowance for doubtful accounts balances were $39 million and $19 million at December 31, 2020, and 2019, respectively, and bad debt write-offs were not material.

Inventories

Our inventories are stated at the lower of cost or net realizable value. For the years ended December 31, 2020 and 2019, approximately 14 percent and 14 percent, respectively, of our consolidated inventories (primarily heavy-duty and high-horsepower engines and parts) were valued using the last-in, first-out (LIFO) cost method. The cost of other inventories is generally valued using the first-in, first-out (FIFO) cost method. Our inventories at interim and year-end reporting dates include estimates for adjustments related to annual physical inventory results and for inventory cost changes under the LIFO cost method. Due to significant movements of partially-manufactured components and parts between manufacturing plants, we do not internally measure, nor do our accounting systems provide, a meaningful segregation between raw materials and work-in-process. See Note 6, "INVENTORIES," for additional information.

Property, Plant and Equipment

We record property, plant and equipment at cost, inclusive of assets under capital leases in 2018 and finance lease assets starting in 2019, with the adoption of the new lease standard. We depreciate the cost of the majority of our property, plant and equipment using the straight-line method with depreciable lives ranging from 20 to 40 years for buildings and 3 to 15 years for machinery, equipment and fixtures. Finance lease (capital lease in 2018) asset amortization is recorded in depreciation expense. We expense normal maintenance and repair costs as incurred. Depreciation expense totaled $504 million, $494 million and $455 million for the years ended December 31, 2020, 2019 and 2018, respectively. See Note 7, "PROPERTY, PLANT AND EQUIPMENT" and Note 8, "LEASES," for additional information.

Impairment of Long-Lived Assets

We review our long-lived assets for possible impairment whenever events or circumstances indicate that the carrying value of an asset or asset group may not be recoverable. We assess the recoverability of the carrying value of the long-lived assets at the lowest level for

which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. An impairment of a long-lived asset or asset group exists when the expected future pre-tax cash flows (undiscounted and without interest charges) estimated to be generated by the asset or asset group is less than its carrying value. If these cash flows are less than the carrying value of such asset or asset group, an impairment loss is measured based on the difference between the estimated fair value and carrying value of the asset or asset group. Assumptions and estimates used to estimate cash flows in the evaluation of impairment and the fair values used to determine the impairment are subject to a degree of judgment and complexity. Any changes to the assumptions and estimates resulting from changes in actual results or market conditions from those anticipated may affect the carrying value of long-lived assets and could result in a future impairment charge.

Lease Policies

We adopted the new standard on January 1, 2019, using a modified retrospective approach and as a result did not adjust prior periods. Adoption of the standard resulted in the recording of $450 million of operating lease ROU assets and operating lease liabilities, but did not have a material impact on our net income or cash flows.

We determine if an arrangement contains a lease in whole or in part at the inception of the contract. Right-of-use (ROU) assets represent our right to use an underlying asset for the lease term while lease liabilities represent our obligation to make lease payments arising from the lease. All leases greater than 12 months result in the recognition of a ROU asset and a liability at the lease commencement date based on the present value of the lease payments over the lease term. As most of our leases do not provide the information required to determine the implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. This rate is determined considering factors such as the lease term, our credit standing and the economic environment of the location of the lease. We use the implicit rate when readily determinable.

Our lease terms include all non-cancelable periods and may include options to extend (or to not terminate) the lease when it is reasonably certain that we will exercise that option. Leases that have a term of 12 months or less at the commencement date are expensed on a straight-line basis over the lease term and do not result in the recognition of an asset or a liability.

Lease expense for operating leases is recognized on a straight-line basis over the lease term. Lease expense for finance leases are generally front-loaded as the finance lease ROU asset is depreciated on a straight-line basis, but interest expense on the liability is recognized utilizing the interest method that results in more expense during the early years of the lease. We have lease agreements with lease and non-lease components, primarily related to real estate, vehicle and information technology (IT) assets. For vehicle and real estate leases, we account for the lease and non-lease components as a single lease component. For IT leases, we allocate the payment between the lease and non-lease components based on the relative value of each component. See Note 8, "LEASES," for additional information.

Goodwill

We have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value as a basis for determining whether it is necessary to perform an annual quantitative goodwill impairment test. We have elected this option on certain reporting units. The quantitative impairment test is only required if an entity determines through this qualitative analysis that it is more likely than not that the fair value of the reporting unit is less than its carrying value. In addition, the carrying value of goodwill must be tested for impairment on an interim basis in certain circumstances where impairment may be indicated. We perform our annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value.

When we are required or opt to perform the quantitative impairment test, the fair value of each reporting unit is estimated with either the market approach or the income approach using a discounted cash flow model. Our income approach method uses a discounted cash flow model in which cash flows anticipated over several periods, plus a terminal value at the end of that time horizon, are discounted to their present value using an appropriate rate of return. Our reporting units are generally defined as one level below an operating segment. However, there are three situations where we have aggregated two or more reporting units which share similar economic characteristics and thus are aggregated into a single reporting unit for testing purposes. These three situations are described further below:

•Within our Components segment, our emission solutions and filtration businesses have been aggregated into a single reporting unit,

•Within our New Power segment, our electrified power, fuel cell and hydrogen technologies businesses have been aggregated into a single reporting unit and

Table of Contents

•Our Distribution segment is considered a single reporting unit as it is managed geographically and all regions share similar economic characteristics and provide similar products and services.

At December 31, 2020, our recorded goodwill was $1,293 million, approximately 42 percent of which resided in the automated transmissions reporting unit, 30 percent in the aggregated emission solutions and filtration reporting unit, 20 percent in the new power reporting unit and 6 percent in the distribution reporting unit. Changes in our projections or estimates, a deterioration of our operating results and the related cash flow effect or a significant increase in the discount rate could decrease the estimated fair value of our reporting units and result in a future impairment of goodwill. See Note 9, "GOODWILL AND OTHER INTANGIBLE ASSETS," for additional information.

Other Intangible Assets

We capitalize other intangible assets, such as trademarks, patents and customer relationships, that have been acquired either individually or with a group of other assets. These intangible assets are amortized on a straight-line basis over their estimated useful lives generally ranging from 3 to 25 years. Intangible assets are reviewed for impairment when events or circumstances indicate that the carrying value may not be recoverable over the remaining lives of the assets. See Note 9, "GOODWILL AND OTHER INTANGIBLE ASSETS," for additional information.

Software

We capitalize software that is developed or obtained for internal use. Software costs are amortized on a straight-line basis over their estimated useful lives generally ranging from 2 to 12 years. Software assets are reviewed for impairment when events or circumstances indicate that the carrying value may not be recoverable over the remaining lives of the assets. Upgrades and enhancements are capitalized if they result in significant modifications that enable the software to perform tasks it was previously incapable of performing. Software maintenance, training, data conversion and business process reengineering costs are expensed in the period in which they are incurred. See Note 9, "GOODWILL AND OTHER INTANGIBLE ASSETS," for additional information.

Warranty

We estimate and record a liability for base warranty programs at the time our products are sold. Our estimates are based on historical experience and reflect management's best estimates of expected costs at the time products are sold and subsequent adjustment to those expected costs when actual costs differ. Factors considered in developing these estimates included component failure rates, repair costs and the point of failure within the product life cycle. As a result of the uncertainty surrounding the nature and frequency of product campaigns, the liability for such campaigns is recorded when we commit to a recall action or when a recall becomes probable and estimable, which generally occurs when it is announced. The liability for these campaigns is reflected in the provision for warranties issued. We review and assess the liability for these programs on a quarterly basis. We also assess our ability to recover certain costs from our suppliers and record a receivable when we believe a recovery is probable. In addition to costs incurred on warranty and product campaigns, from time to time we also incur costs related to customer satisfaction programs for items not covered by warranty. We accrue for these costs when agreement is reached with a specific customer. These costs are not included in the provision for warranties, but are included in cost of sales. In addition, we sell extended warranty coverage on most of our engines. See Extended Warranty policy discussion above and Note 12, "PRODUCT WARRANTY LIABILITY," for additional information.

Research and Development

Table of Contents

time to time, we enter into agreements with customers and government agencies to fund a portion of the research and development costs of a particular project. When not associated with a sales contract, we generally account for these reimbursements as an offset to the related research and development expenditure. Research and development expenses, net of contract reimbursements, were $903 million, $998 million and $894 million for the years ended December 31, 2020, 2019 and 2018, respectively. Contract reimbursements were $86 million, $90 million and $120 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Related Party Transactions

In accordance with the provisions of various joint venture agreements, we may purchase products and components from our joint ventures, sell products and components to our joint ventures and our joint ventures may sell products and components to unrelated parties. Joint venture transfer prices may differ from normal selling prices. Certain joint venture agreements transfer product at cost, some transfer product on a cost-plus basis, and others transfer product at market value. Our related party sales are presented on the face of our Consolidated Statements of Net Income. Our related party purchases were not material to our financial position or results of operations.

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

In August 2018, the Financial Accounting Standards Board (FASB) issued a new standard that aligns the accounting for implementation costs incurred in a cloud computing arrangement accounted for as a service contract with the model currently used for internal use software costs. Under the new standard, costs that meet certain criteria will be required to be capitalized on the balance sheet and subsequently amortized over the term of the hosting arrangement. We adopted the standard on January 1, 2020, on a prospective basis as allowed by the standard. The adoption did not have a material impact on our Consolidated Financial Statements.

On January 1, 2020, we adopted the new FASB standard related to accounting for credit losses on financial instruments. This standard introduced new guidance for accounting for credit losses on instruments including trade receivables and held-to-maturity debt securities. The standard required entities to record a cumulative effect adjustment to the statement of financial position. We recorded a net decrease to opening retained earnings of $4 million, net of tax, as of January 1, 2020, due to the cumulative impact of adopting the new standard. The impact to any individual financial statement line item as a result of applying the new standard, as compared to the old standard, was not material for the year ended December 31, 2020.

In March 2020, the FASB amended its standard to provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendment allows entities to elect not to apply certain modification accounting requirements to contracts affected by reference rate reform if certain criteria are met. An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination. Entities can elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met. These expedients also apply to interest rate locks. The guidance was effective upon issuance and expires after December 31, 2022. The amendment did not have an effect on our Consolidated Financial Statements at December 31, 2020. We are still evaluating which contracts will be impacted by reference rate reform, but the expedients will allow us to make permitted changes prior to the expiration of the amendments without resulting in a material impact to our Consolidated Financial Statements.

NOTE 2. REVENUE FROM CONTRACTS WITH CUSTOMERS

Long-term Contracts

Most of our contracts are for a period of less than one year. We have certain long-term maintenance agreements, construction contracts and extended warranty coverage arrangements that span a period in excess of one year. The aggregate amount of the transaction price for long-term maintenance agreements and construction contracts allocated to performance obligations that had not been satisfied as of December 31, 2020, was $879 million. We expect to recognize the related revenue of $160 million over the next 12 months and $719 million over periods up to 10 years. See Note 12,"PRODUCT WARRANTY LIABILITY," for additional disclosures on extended warranty coverage arrangements. Our other contracts generally are for a duration of less than one year, include payment terms that correspond to the timing of costs incurred when providing goods and services to our customers or represent sales-based royalties.

Manufacturing Entities

Our manufacturing joint ventures have generally been formed with customers and are primarily intended to allow us to increase our market penetration in geographic regions, reduce capital spending, streamline our supply chain management and develop technologies. Our largest manufacturing joint ventures are based in China and are included in the list below. Our engine manufacturing joint ventures are supplied by our Components segment in the same manner as it supplies our wholly-owned Engine segment and Power Systems segment manufacturing facilities. Our Components segment joint ventures and wholly-owned entities provide electronics, fuel systems, filtration, aftertreatment systems, turbocharger products and automated transmissions that are used with our engines as well as some competitors' products. The results and investments in our joint ventures in which we have 50 percent or less ownership interest (except for Eaton Cummins Automated Transmission Technologies joint venture which is consolidated due to our majority voting interest) are included in “Equity, royalty and interest income from investees” and “Investments and advances related to equity method investees” in our Consolidated Statements of Net Income and Consolidated Balance Sheets, respectively.

•Beijing Foton Cummins Engine Co., Ltd. - Beijing Foton Cummins Engine Co., Ltd. is a joint venture in China with Beiqi Foton Motor Co., Ltd., a commercial vehicle manufacturer, which has two distinct lines of business - a light-duty business and a heavy-duty business. The light-duty business produces our families of ISF 2.8 liter to 4.5 liter high performance light-duty diesel engines in Beijing. These engines are used in light-duty and medium-duty commercial trucks, pick-up trucks, buses, multipurpose and sport utility vehicles with main markets in China, Brazil and Russia. Certain types of small construction equipment and industrial applications are also served by these engine families. The heavy-duty business produces the X11, X12 and X13, ranging from 10.5 liter to 12.9 liter, high performance heavy-duty diesel engines in Beijing. Certain types of construction equipment and industrial applications are also served by these engine families.

Distribution Entities

We have an extensive worldwide distributor and dealer network through which we sell and distribute our products and services. Generally, our distributors are divided by geographic region with some of our distributors being wholly-owned by Cummins, some partially-owned and some independently owned. We consolidate all wholly-owned distributors and partially-owned distributors where we are the primary beneficiary and account for other partially-owned distributors using the equity method of accounting.

Table of Contents

In certain cases where we own a partial interest in a distributor, we may be obligated to purchase the other equity holders' interests if certain events occur (such as the death or resignation of the distributor principal or a change in control of Cummins Inc.). The purchase consideration of the equity interests may be determined based on the fair value of the distributor's assets. Repurchase obligations and practices vary by geographic region.

All distributors that are partially-owned are considered to be related parties in our Consolidated Financial Statements.

Our effective tax rate for 2020 was 22.5 percent compared to 20.0 percent for 2019 and 20.6 percent for 2018. The year ended December 31, 2020, contained $26 million, or $0.17 per share, of unfavorable net discrete tax items, primarily due to $33 million of unfavorable changes in tax reserves and $10 million of withholding tax adjustments, partially offset by $15 million of favorable changes due to the India Tax Law Change. The India Tax Law Change eliminated the dividend distribution tax and replaced it with a lower rate withholding tax as the burden shifted from the dividend payor to the dividend recipient for a net favorable income statement impact of $35 million.

The year ended December 31, 2019, contained $34 million of favorable net discrete tax items, primarily due to withholding taxes and provision to return adjustments.

The year ended December 31, 2018, contained $14 million of favorable net discrete tax items, primarily due to $26 million of other favorable discrete tax items, partially offset by $12 million of unfavorable discrete tax items related to final adjustments for 2017 tax legislation.

The India Tax Law Change resulted in the following adjustments to the Consolidated Statements of Net Income for the year ended December 31, 2020:




In millions	Favorable (Unfavorable)
Equity, royalty and interest income from investees	$	37
Income tax expense (1)	17

At December 31, 2020, $3.7 billion of non-U.S. earnings are considered indefinitely reinvested in operations outside the U.S. for which deferred taxes have not been provided. Determination of the related deferred tax liability, if any, is not practicable because of the complexities associated with the hypothetical calculation.

Our 2020 U.S. carryforward benefits include $223 million of state credit and net operating loss carryforward benefits that begin to expire in 2021. Our foreign carryforward benefits include $159 million of net operating loss carryforwards that begin to expire in 2021. A valuation allowance is recorded to reduce the gross deferred tax assets to an amount we believe is more likely than not to be realized. The valuation allowance is $346 million and increased in 2020 by a net $29 million. The valuation allowance is primarily attributable to the uncertainty regarding the realization of a portion of the U.S. state and foreign net operating loss and tax credit carryforward benefits.

We have also accrued interest expense related to the unrecognized tax benefits of $17 million, $5 million and $4 million as of December 31, 2020, 2019 and 2018, respectively. We recognize potential accrued interest and penalties related to unrecognized tax benefits in income tax expense.

Audit outcomes and the timing of audit settlements are subject to significant uncertainty. Although we believe that adequate provision has been made for such issues, there is the possibility that the ultimate resolution of such issues could have an adverse effect on our earnings. Conversely, if these issues are resolved favorably in the future, the related provision would be reduced, thus having a positive impact on earnings.

As a result of our global operations, we file income tax returns in various jurisdictions including U.S. federal, state and foreign jurisdictions. We are routinely subject to examination by taxing authorities throughout the world, including Australia, Belgium, Brazil, Canada, China, France, India, Mexico, the U.K. and the U.S. With few exceptions, our U.S. federal, major state and foreign jurisdictions are no longer subject to income tax assessments for years before 2016.

(1) Unrealized gains and losses for debt securities are recorded in other comprehensive income while unrealized gains and losses for equity securities are recorded in "Other income, net" in our Consolidated Statements of Net Income.

All debt securities are classified as available-for-sale. All marketable securities presented use a Level 2 fair value measure. The fair value of Level 2 securities is estimated using actively quoted prices for similar instruments from brokers and observable inputs where available, including market transactions and third-party pricing services, or net asset values provided to investors. We do not currently have any Level 3 securities, and there were no transfers between Level 2 or 3 during 2020 or 2019.

A description of the valuation techniques and inputs used for our Level 2 fair value measures is as follows:

•Debt mutual funds— The fair value measures for the vast majority of these investments are the daily net asset values published on a regulated governmental website. Daily quoted prices are available from the issuing brokerage and are used on a test basis to corroborate this Level 2 input.

Table of Contents

•Certificates of deposit and bank debentures— These investments provide us with a contractual rate of return and generally range in maturity from three months to five years. The counterparties to these investments are reputable financial institutions with investment grade credit ratings. Since these instruments are not tradable and must be settled directly by us with the respective financial institution, our fair value measure is the financial institution's month-end statement.

•Equity mutual funds— The fair value measures for these investments are the net asset values published by the issuing brokerage. Daily quoted prices are available from reputable third-party pricing services and are used on a test basis to corroborate this Level 2 input measure.

•Debt securities— The fair value measures for these securities are broker quotes received from reputable firms. These securities are infrequently traded on a national exchange and these values are used on a test basis to corroborate our Level 2 input measure.

NOTE 8. LEASES

Our lease portfolio consists primarily of real estate and equipment leases. Our real estate leases primarily consist of land, office, distribution, warehousing and manufacturing facilities. These leases typically range in term from 2 to 50 years and may contain renewal options for periods up to 10 years at our discretion. Our equipment lease portfolio consists primarily of vehicles (including service vehicles), forktrucks and IT equipment. These leases typically range in term from two years to three years and may contain renewal options. Our leases generally do not contain variable lease payments other than (1) certain foreign real estate leases which have payments indexed to inflation and (2) certain real estate executory costs (such as taxes, insurance and maintenance), which are

NOTE 11. DEBT

Loans Payable and Commercial Paper

Loans payable at December 31, 2020 and 2019 were $169 million and $100 million, respectively, and consisted primarily of notes payable to financial institutions. The weighted-average interest rate for notes payable, bank overdrafts and current maturities of long-term debt at December 31 was as follows:


	2020		2019		2018
Weighted-average interest rate	2.53	%	3.20	%	4.66	%

We can issue up to $3.5 billion of unsecured, short-term promissory notes (commercial paper) pursuant to the Board of Directors (the Board) authorized commercial paper programs. The programs facilitate the private placement of unsecured short-term debt through third-party brokers. We intend to use the net proceeds from the commercial paper borrowings for general corporate purposes. We had $323 million and $660 million in outstanding borrowings under our commercial paper programs at December 31, 2020 and 2019, respectively. The weighted-average interest rate for commercial paper at December 31 was as follows:


	2020			2019		2018
Weighted-average interest rate	(0.01)	%	(1)	1.82	%	2.59	%

(1) The weighted-average interest rate, inclusive of all brokerage fees, was negative 0.01 percent at December 31, 2020. This includes $123 million of borrowings under the EUR program that were at a negative weighted-average interest rate of 0.34 percent and $200 million of borrowings under the U.S. program at a weighted-average interest rate of 0.19 percent.

On April 14, 2020, we were approved for the Federal Reserve Bank of New York’s Commercial Paper Funding Facility (CPFF) program to assure access to the commercial paper funding markets during volatile credit market conditions. The CPFF was intended to provide a liquidity backstop to U.S. issuers of commercial paper through a special purpose vehicle (SPV). The facility allows us, based on our current short-term credit rating, to issue three-month unsecured commercial paper at a rate equal to a +110 basis point spread over the three-month overnight index swap rate on the date of issuance. The maximum amount of commercial paper that we may issue at any time through this program is $1.5 billion less the total principal amount of all other outstanding commercial paper that we have issued. We retain full access to our Board authorized $3.5 billion commercial paper program, as reduced by any amounts issued under this facility. The SPV is currently scheduled to cease purchasing commercial paper on March 17, 2021. At December 31, 2020, there were no outstanding borrowings under the CPFF program.

Revolving Credit Facilities

On August 19, 2020, we entered into an amended and restated 364-day credit agreement that allows us to borrow up to $1.5 billion of unsecured funds at any time prior to August 18, 2021. This credit agreement amended and restated the prior $1.5 billion 364-day credit facility that matured on August 19, 2020.

On August 22, 2018, we entered into a new 5-year revolving credit agreement with a syndicate of lenders and we amended the agreement on August 21, 2019. The amended credit agreement provides us with a $2 billion senior unsecured revolving credit facility until August 22, 2023. Amounts payable under our revolving credit facility will rank pro rata with all of our unsecured, unsubordinated indebtedness. Advances under the facility bear interest at (i) an alternate base rate or (ii) a rate equal to the adjusted LIBOR plus an applicable margin based on the credit ratings of our outstanding senior unsecured long-term debt. Based on our current

Table of Contents

long-term debt ratings, the applicable margin on adjusted LIBOR rate loans was 0.75 percent per annum as of December 31, 2020. Advances under the facility may be prepaid without premium or penalty, subject to customary breakage costs.

Both credit agreements include various covenants, including, among others, maintaining a net debt to total capital leverage ratio of no more than 0.65 to 1.0. At December 31, 2020, we were in compliance with the covenants. We maintain credit facilities at the current or higher aggregate amounts by renewing or replacing these facilities at or before expiration. These revolving credit facilities are maintained primarily to provide backup liquidity for our commercial paper borrowings and for general corporate purposes. There were no outstanding borrowings under these facilities at December 31, 2020.

At December 31, 2020, our $323 million of commercial paper outstanding effectively reduced the $3.5 billion available capacity under our revolving credit facilities to $3.2 billion.

At December 31, 2020, we also had $256 million available for borrowings under our international and other domestic credit facilities.

In millions	2021		2022		2023		2024		2025
Principal payments	$	62	$	49	$	526	$	23	$	506

On August 24, 2020, we issued $2 billion aggregate principal amount of senior unsecured notes consisting of $500 million aggregate principal amount of 0.75% senior unsecured notes due in 2025, $850 million aggregate principal amount of 1.50% senior unsecured notes due in 2030 and $650 million aggregate principal amount of 2.60% senior unsecured notes due in 2050. We received net proceeds of $1.98 billion. The senior unsecured notes pay interest semi-annually on March 1 and September 1, commencing on March 1, 2021. The indenture governing the senior unsecured notes contains covenants that, among other matters, limit (i) our ability to consolidate or merge into, or sell, assign, convey, lease, transfer or otherwise dispose of all or substantially all of our and our subsidiaries' assets to another person, (ii) our and certain of our subsidiaries' ability to create or assume liens and (iii) our and certain of our subsidiaries' ability to engage in sale and leaseback transactions.

Table of Contents

The $250 million 7.125% debentures and $165 million 5.65% debentures are unsecured and are not subject to any sinking fund requirements. We can redeem these debentures at any time prior to maturity at the greater of par plus accrued interest or an amount designed to ensure that the debenture holders are not penalized by the early redemption.

Our debt agreements contain several restrictive covenants. The most restrictive of these covenants applies to our revolving credit facility which will upon default, among other things, limit our ability to incur additional debt or issue preferred stock, enter into sale-leaseback transactions, sell or create liens on our assets, make investments and merge or consolidate with any other entity. At December 31, 2020, we were in compliance with all of the covenants under our borrowing agreements.

Shelf Registration

As a well-known seasoned issuer, we filed an automatic shelf registration for an undetermined amount of debt and equity securities with the Securities and Exchange Commission on February 13, 2019. Under this shelf registration we may offer, from time to time, debt securities, common stock, preferred and preference stock, depositary shares, warrants, stock purchase contracts and stock purchase units. Our current shelf is scheduled to expire in February 2022.

Interest Expense

For the years ended December 31, 2020, 2019 and 2018, total interest incurred was $102 million, $112 million and $116 million, respectively, and interest capitalized was $2 million, $3 million and $2 million, respectively.

Interest Rate Risk

In 2019 we entered into $350 million of interest rate lock agreements, and in the first half of 2020 we entered into an additional $150 million of lock agreements to reduce the variability of the cash flows of the interest payments on a total of $500 million of fixed rate debt forecast to be issued in 2023 to replace our senior notes at maturity. The terms of the rate locks mirror the time period of the expected fixed rate debt issuance and the expected timing of interest payments on that debt. The gains and losses on these derivative instruments will be initially recorded in "Other comprehensive income" and will be released to earnings in "Interest expense" in future periods to reflect the difference in (1) the fixed rates economically locked in at the inception of the hedge and (2) the actual fixed rates established in the debt instrument at issuance.

The following table summarizes the interest rate lock activity in AOCL:

Interest rate locks	$	(22)	$	—	(10)	—

We had a series of interest rate swaps to effectively convert our September 2013, $500 million debt issue, due in 2023, from a fixed rate of 3.65 percent to a floating rate equal to the one-month LIBOR plus a spread. The debt is included in the Consolidated Balance Sheets as "Long-term debt." The terms of the swaps mirrored those of the debt, with interest paid semi-annually. The swaps were designated, and were accounted for, as fair value hedges. The gain or loss on these derivative instruments, as well as the offsetting gain or loss on the hedged item attributable to the hedged risk, were recognized in current income as “Interest expense.” The net swap settlements that accrued each period were also reported in the Consolidated Financial Statements as "Interest expense." A basis adjustment related to credit risk, excluded from the assessment of effectiveness, was being amortized over the life of the hedge using a straight-line method and was considered de minimis.

Engine System Campaign Accrual

During 2017, the California Air Resources Board (CARB) and the U.S. Environmental Protection Agency (EPA) selected certain of our pre-2013 model year engine systems for additional emissions testing. Some of these engine systems failed CARB and EPA tests as a result of degradation of an aftertreatment component. In the second quarter of 2018, we reached agreement with the CARB and EPA regarding our plans to address the affected populations. From the fourth quarter of 2017 through the second quarter of 2018, we recorded charges for the expected costs of field campaigns to repair these engine systems.

The campaigns launched in the third quarter of 2018 are being completed in phases across the affected population. The total engine system campaign charge, excluding supplier recoveries, was $410 million. In the fourth quarter of 2020, we recorded an additional $20 million charge related to this campaign, as a change in estimate, to bring the total campaign, excluding supplier recoveries, to $430 million. At December 31, 2020, the remaining accrual balance was $151 million.

NOTE 13. PENSIONS AND OTHER POSTRETIREMENT BENEFITS

Pension Plans

We sponsor several pension plans covering substantially all employees. Generally, pension benefits for salaried employees are determined as a function of employee’s compensation. Pension benefits for most hourly employees are determined similarly and as a function of employee’s compensation, with the exception of a small group of hourly employees whose pension benefits were grandfathered in accordance with agreements with their union representation and are based on their years of service and compensation during active employment. The level of benefits and terms of vesting may vary among plans and are offered in accordance with applicable laws. Pension plans assets are administered by trustees and are principally invested in fixed income securities and equity securities. It is our policy to make contributions to our various qualified plans in accordance with statutory and contractual funding requirements, and any additional contributions we determine are appropriate.

In addition to the pension plans in the above table, we also maintain less significant defined benefit pension plans in 14 other countries outside of the U.S. and the U.K. that comprise approximately 3 percent and 5 percent of our pension plan assets and obligations, respectively, at December 31, 2020. These plans are reflected in "Other liabilities" on our Consolidated Balance Sheets. In 2020 and 2019, we made $16 million and $15 million of contributions to these plans, respectively.

Plan Assets

Our investment policies in the U.S. and U.K. provide for the rebalancing of assets to maintain our long-term strategic asset allocation. We are committed to this long-term strategy and do not attempt to time the market. Given empirical evidence that asset allocation is critical, rebalancing of the assets has and continues to occur, maintaining the proper weighting of assets to achieve the expected total portfolio returns. We believe that our portfolio is highly diversified and does not have any significant exposure to concentration risk. The plan assets for our defined benefit pension plans do not include any of our common stock.

U.S. Plan Assets

For the U.S. qualified pension plans, our assumption for the expected return on assets was 6.25 percent in 2020. Projected returns are based primarily on broad, publicly traded equity and fixed income indices and forward-looking estimates of active portfolio and investment management. We expect additional positive returns from this active investment management. Based on the historical returns and forward-looking return expectations, we have elected to maintain our assumption of 6.25 percent in 2021.

The primary investment objective is to exceed, on a net-of-fee basis, the rate of return of a policy portfolio comprised of the following:


Asset Class	Target		Range
U.S. equities	7.0	%	+5.0/ -5.0%
Non-U.S. equities	2.0	%	+3.0/ -2.0%
Global equities	6.0	%	+3.0/ -3.0%
Total equities	15.0	%
Real assets	6.5	%	+3.5/ -6.5%
Private equity/venture capital	6.5	%	+3.5/ -6.5%
Opportunistic credit	4.0	%	+6.0/ -4.0%
Fixed income	68.0	%	+5.0/ -5.0%
Total	100.0	%

The fixed income component is structured to represent a custom bond benchmark that will closely hedge the change in the value of our liabilities. This component is structured in such a way that its benchmark covers approximately 100 percent of the plan's exposure to changes in its discount rate (AA corporate bond yields). In order to achieve a hedge on more than the targeted 68 percent of plan assets invested in fixed income securities, our Benefits Policy Committee (BPC) permits the fixed income managers, other managers or the custodian/trustee to utilize derivative securities, as part of a liability driven investment strategy to further reduce the plan's risk of declining interest rates. However, all managers hired to manage assets for the trust are prohibited from using leverage unless approved by the BPC.

U.K. Plan Assets

For the U.K. qualified pension plans, our assumption for the expected return on assets was 4.0 percent in 2020. The methodology used to determine the rate of return on pension plan assets in the U.K. was based on establishing an equity-risk premium over current long-term bond yields adjusted based on target asset allocations. Our strategy with respect to our investments in these assets is to be invested in a suitable mixture of return-seeking assets such as equities, real estate and liability matching assets such as group annuity insurance contracts and duration matched bonds. Therefore, the risk and return balance of our U.K. asset portfolio should reflect a long-term horizon. To achieve these objectives we have established the following targets:


Asset Class	Target
Equities	10.0	%
Private markets/secure income assets	18.0	%
Credit	7.5	%
Diversifying strategies	8.0	%

Fixed income/insurance annuity	55.5	%
Cash	1.0	%
Total	100.0	%

As part of our strategy in the U.K. we have not prohibited the use of any financial instrument, including derivatives. As in the U.S. plan, derivatives may be used to better match liability duration and are not used in a speculative way. The 55.5 percent fixed income component is structured in a way that covers approximately 80 percent of the plan's exposure to changes in its discount rate. Based on the above discussion, we have elected an assumption of 4.0 percent in 2021.

Level 3 Assets

The investments in an insurance annuity contract, venture capital, private equity and real estate, for which quoted market prices are not available, are valued at their estimated fair value as determined by applicable investment managers or by quarterly financial statements of the funds. These financial statements are audited at least annually. In conjunction with our investment consultant, we monitor the fair value of the insurance contract as periodically reported by our insurer and their counterparty risk. The fair value of all real estate properties, held in the partnerships, are valued at least once per year by an independent professional real estate valuation firm. Fair value generally represents the fund's proportionate share of the net assets of the investment partnerships as reported by the general partners of the underlying partnerships. Some securities with no readily available market are initially valued at cost, utilizing independent professional valuation firms as well as market comparisons with subsequent adjustments to values which reflect either the basis of meaningful third-party transactions in the private market or the fair value deemed appropriate by the general partners of the underlying investment partnerships. In such instances, consideration is also given to the financial condition and operating results of the issuer, the amount that the investment partnerships can reasonably expect to realize upon the sale of the securities and any other factors deemed relevant. The estimated fair values are subject to uncertainty and therefore may differ from the values that would have been used had a ready market for such investments existed and such differences could be material.

Estimated Future Contributions and Benefit Payments

We plan to contribute approximately $75 million to our defined benefit pension plans in 2021. The table below presents expected future benefit payments under our pension plans:

(1)Earnings per share in each quarter is computed using the weighted-average number of shares outstanding during that quarter while earnings per share for the full year is computed using the weighted-average number of shares outstanding during the year. Thus, the sum of the four quarters earnings per share may not equal the full year earnings per share.
(2) Net income attributable to Cummins Inc. and earnings per share were negatively impacted by $119 million ($90 million after-tax) of restructuring actions in the fourth quarter of 2019 ($0.59 per basic share and $0.59 per diluted share).
