Information Concerning Eaton's Business in General
Raw Materials
Eaton's major requirements for raw materials include iron, steel, copper, nickel, aluminum, lead, silver, gold, titanium, rubber, plastic, electronic components, chemicals, and fluids. Materials are purchased in various forms, such as bar stock, extrusions, castings, forgings, powder metal, coils, sheets, strips, stampings, plastic resins and pellets. Raw materials, as well as parts and other components, are purchased from many suppliers. Under normal circumstances, the Company has no difficulty obtaining its raw materials. However, as global economies recovered from the COVID-19 pandemic in 2021, some of our businesses were impacted by inflation and supply chain constraints, including limited availability of select materials and delivery delays. During this time, we worked closely with our suppliers to manage and minimize the impact on our supply chain. Additional information related to the impact of supply chain constraints and inflation is presented in “Management's Discussion and Analysis of Financial Condition and Results of Operations” of this Form 10-K.
Patents and Trademarks
Eaton considers its intellectual property, including without limitation patents, trade names, domain names, trademarks, confidential information, and trade secrets to be of significant value to its business as a whole. The Company's products are manufactured, marketed and sold using a portfolio of patents, trademarks, licenses, and other forms of intellectual property, some of which expire in the future. Eaton develops and acquires new intellectual property on an ongoing basis and considers all of its intellectual property to be valuable. Based on the broad scope of the Company's product lines, management believes that the loss or expiration of any single intellectual property right would not have a material effect on Eaton's consolidated financial statements or its business segments. The Company's policy is to file applications and obtain patents for the majority of its novel and innovative new products including product modifications and improvements.
Environmental Contingencies
Our comprehensive sustainability strategy is driven by our mission to improve the quality of life and the environment. We are committed to reducing our footprint, eliminating waste, and making the best use of natural resources. Operations of the Company involve the use and disposal of certain substances regulated under environmental protection laws. Eaton continues to modify processes on an ongoing, regular basis in order to reduce the impact on the environment, including the reduction or elimination of certain chemicals used in, and wastes generated from, operations. Compliance with laws that have been enacted or adopted regulating the discharge of materials into the environment, or otherwise relating to the protection of the environment, are not expected to have a material adverse effect upon capital expenditures, including expenditures for environmental control facilities, earnings or the competitive position of the Company. Compliance with future environmental protection laws may require an increase in capital expenditures. Information regarding the Company's liabilities related to environmental matters is presented in Note 10 of the Notes to the Consolidated Financial Statements.

Eaton uses and monitors a variety of metrics to ensure our objectives related to employee attraction, development, and retention are met. Most notably, Eaton tracks the following:
Inclusion and Diversity
Eaton is committed to having a workforce that is diverse and inclusive at all levels, reflecting the diversity of our customers and communities. Our success depends on our ability to attract and retain the best employees without regard to race, color, social or economic status, religion, national origin, marital status, age, veteran status, sexual orientation, gender identity, or any protected status. It is the policy of the Company to make all decisions regarding employment, including hiring, compensation, training, promotions, transfers, or lay-offs, based on the principle of equal employment opportunity and without discrimination.
At December 31, 2021, Eaton’s distribution by gender, and United States distribution by minority status, is as follows:

|  | Total Global |  | Number of women (Global) |  | Percentage of women (Global) |  | U.S. total |  | Number of minorities (U.S. only)1 |  | Percentage of minorities (U.S. only)1
Board of directors |  | 12 |  |  | 4 |  |  | 33.3 | % |  | 10 |  |  | 4 |  |  | 40.0 | %
Global leadership team |  | 25 |  |  | 6 |  |  | 24.0 | % |  | 23 |  |  | 13 |  |  | 56.5 | %
Executives |  | 587 |  |  | 137 |  |  | 23.3 | % |  | 413 |  |  | 70 |  |  | 16.9 | %
Managers |  | 7,185 |  |  | 1,697 |  |  | 23.6 | % |  | 3,668 |  |  | 731 |  |  | 19.9 | %
All other employees |  | 78,150 |  |  | 26,827 |  |  | 34.3 | % |  | 20,171 |  |  | 7,340 |  |  | 36.4 | %
All employees |  | 85,947 |  |  | 28,667 |  |  | 33.4 | % |  | 24,275 |  |  | 8,154 |  |  | 33.6 | %

1 Excluding Puerto Rico
At Eaton, one of our aspirational goals is to be a model of inclusion and diversity among our peers. Our plan to achieve this goal encompasses a number of actions, including an examination into our programs, practices, processes, and policies to look for opportunities to strengthen our support of underrepresented individuals, groups and businesses across our operations.
Compensation
A key component of Eaton’s attraction and retention strategy is competitive compensation. Eaton regularly benchmarks its compensation practices with industry peers to maintain a top performing workforce. Eaton’s 2021 total employee costs was $5.5 billion including salaries, wages, equity-based compensation, pension and other benefits. The total compensation of our median employee on October 1, 2020, as reported in our 2021 Proxy Statement filed in March 2021, and as calculated in accordance with Item 402(u) of Regulation S-K, was $63,951.
Safety
Throughout our operations, our goal is to have no safety incidents and we continue to make progress towards that goal. For example, in 2020 we reduced our Total Recordable Case Rate (TRCR) by 26% (0.40) and our Days Away Case Rate (DACR) by 26% (0.17) compared to 2019. Our TRCR of 0.40 approaches our long-term goal of 0.25, which we believe is a world-class safety rate.
Further, in 2021, the Company took a number of measures to continue to protect our workforce from the COVID-19 pandemic, including the following as appropriate:
•Training our employees at sites around the world in cleaning and disinfecting protocols
•Enacting social distancing procedures, staggered shifts, a rotating office work schedule, and modified workspace and meeting space layouts as appropriate
•Requiring employees to stay at home if they are feeling ill, and encouraging increased hand washing and hygiene practices across all sites
•Advising employees to take advantage of flexible work options
•Restricting visitors to all sites
•Encouraging vaccination for all employees and at select locations, arranging for vaccination clinics and transportation
•Consulting regularly with doctors and health care organizations
•Updating the Company's response plan as new information became available

Table of contents
In the event an employee suspects they have been exposed to COVID-19, or testing confirms it, sites will implement a response plan that includes:
•Communication with all who may have been exposed
•Disinfecting work stations and common areas
•Shutting down the facility if warranted
These actions are aligned with preventive health protocols of governmental authorities and health organizations including the Centers for Disease Control (U.S.) and the World Health Organization.
Achieving work-life balance
Achieving work-life balance is a common concern of today's employees. Flexible work solutions and inclusive programs will help us remain competitive in attracting and retaining the best talent and make it possible for employees in varied situations to be able to remain at Eaton. Flexible solutions include compressed work weeks, remote working, job sharing, part-time work, flextime, and telework.
Engagement
Fully engaged employees are more productive, innovative, and satisfied in their work. Examples of how we engage our employees include enterprise-wide town halls, hosting informal listening meetings and surveying groups of employees on specific subjects. In addition, we have programs focused on career development of employees at all levels. Our 2021 survey on employee engagement showed a favorable response from 83 percent of employees who completed it. This group reported that they were proud to work at Eaton, felt personal accomplishment from their work, and would recommend Eaton as a place to work. We are committed to a wide range of strategies designed to improve and sustain employee engagement over the long-term.
Item 1A. Risk Factors.
Among the risks that could materially adversely affect Eaton's businesses, financial condition or results of operations are the following:
Operational Risks
Impacts related to, and recovery from, the COVID-19 pandemic could have an adverse effect on our business and results of operations.
The global outbreak of COVID-19 has disrupted economic activity around the world. As a result, we and our employees, suppliers, customers and others have been and may continue to be restricted or prevented from conducting normal business activities, including as a result of shutdowns, travel restrictions and other actions that may be requested or mandated by governmental authorities. While a substantial portion of our businesses and facilities have been classified as essential in jurisdictions in which facility closures have been mandated, we can give no assurance that there will not be additional closures in the future or that our businesses and facilities will be classified as essential in each of the jurisdictions in which we operate. We have experienced and could continue to experience supply and labor shortages as the Company expands its production capacity to meet increased customer demand as global economies recover. The extent to which the COVID-19 pandemic continues to impact our results of operations and financial condition will depend on future developments that are highly uncertain and cannot be predicted, including the resurgence of COVID-19 as a result of new variants, the effectiveness of COVID-19 vaccines and the speed at which populations are vaccinated around the globe, the impact of COVID-19 on economic activity and regulatory actions taken to contain the impact of COVID-19 on public health and the global economy. The impact of COVID-19 may also exacerbate other risks discussed in Item 1A of this Annual Report on Form 10-K, any of which could have a material effect on our results of operations.
If Eaton is unable to protect its information technology infrastructure against service interruptions, data corruption, cyber-based attacks or network security breaches, product or service offerings could be compromised or operations could be disrupted or data confidentiality impaired.
Eaton relies on information technology networks and systems, including the Internet, to process, transmit and store electronic information, and to manage or support a variety of business processes and activities, including procurement, manufacturing, distribution, invoicing and collection. Additionally, many of our products and services include integrated software and information technology that collects data or connects to external and internal systems. Because of this, cybersecurity threats pose a material risk to our business operations.
5

Table of contents
Global cybersecurity threats range from widespread vulnerabilities, sophisticated and targeted measures known as advanced persistent threats, or uncoordinated individual attempts to gain unauthorized access to IT/OT systems. These threats may be directed at Eaton, its products, software embedded in Eaton’s products, or its third-party service providers. The risk is amplified by the increasingly connected nature of our products and systems. These threats may originate from anywhere in the connected world and take the form of phishing, malware, bots, or human-centric attacks. Eaton continually seeks to deploy comprehensive measures to deter, prevent, detect, respond to and mitigate these threats.
As a result of our worldwide operations, we are subject to laws and regulations, including data protection/privacy and cybersecurity laws and regulations, in many jurisdictions. In addition, we operate in an environment in which there are different and potentially conflicting data privacy laws in effect in the various U.S. states and foreign jurisdictions in which we operate and we must understand and comply with each law and standard in each of these jurisdictions while ensuring the data is secure. For example, the Global Data Protection Regulation (GDPR) prefers that we manage personal data in the E.U. and may impose fines of up to four percent of our global revenue in the event of certain violations.
Eaton’s customers, including Governmental Agencies, are increasingly requiring cybersecurity protections and mandating cybersecurity standards which may result in additional operating or production costs. Our cybersecurity program aligns with well-known industry-wide security control frameworks. Despite these efforts, cybersecurity incidents could potentially result in the misappropriation, destruction, corruption or unavailability of critical data and confidential or proprietary information and the disruption of business operations. The potential consequences of a material cybersecurity incident include theft of intellectual property, disruption of operations, reputational damage, adverse health and safety consequences, the loss or misuse of confidential information, product failure, as well as exposure to fines, legal claims or enforcement actions.
The effects of climate change, including weather disruptions and regulatory/market reactions, create uncertainties that could negatively impact our business.
Global increases in greenhouse gas emissions are linked to climate change, and there is a growing consensus that dramatic emissions reductions are needed to avoid severe climate impacts. Extreme weather events linked to climate change, including hurricanes, flooding, wildfires, and high heat/water scarcity, create physical risks to Eaton’s operating locations and supply chains. While Eaton is working to make its own operations carbon neutral by 2030, a global failure to achieve commitments could cause increases in these extreme weather events, political instability, and workforce migration, ultimately increasing Eaton’s cost of doing business.
Regulatory reactions to climate change may pose more stringent obligations on Eaton’s operations and change customer demands. While Eaton is already gearing its portfolio towards products that will reduce carbon and combat climate change, there is a risk that Eaton may not innovate quickly enough to meet changing regulatory or market demands. Increasing demands for metals as the world electrifies may lead to scarcity and increased costs, as may uncertainty over carbon taxes and grid stability during a renewables transition. Despite these uncertainties, we believe Eaton is well positioned to capitalize on secular trends and market opportunities arising from these risks.
Eaton's operations depend on production facilities throughout the world, which subjects them to varying degrees of risk of disrupted production.
Eaton manages businesses with manufacturing facilities worldwide. The Company's manufacturing facilities and operations could be disrupted by a natural disaster, labor strike, war, political unrest, terrorist activity, economic upheaval, or public health concerns such as the spread of COVID-19. Any such disruption could cause delays in shipments of products and the loss of sales and customers, and insurance proceeds may not adequately compensate for losses.
Eaton uses a variety of raw materials and components in its businesses, and significant shortages, price increases, or supplier insolvencies could increase operating costs and adversely impact the competitive positions of Eaton's products.
Eaton's major requirements for raw materials are described above in Item 1 “Raw Materials”. Shortages have affected the prices Eaton's businesses are charged as global economies recover from the COVID-19 pandemic. If this trend continues, the competitive position of our products and services may be impacted, which could have a material adverse impact on operating results.
Further, some of Eaton's suppliers of component parts have increased their prices in response to increases in costs of raw materials that they use to manufacture component parts, including logistics inflation. Should this trend continue or become more prevalent, the Company may not be able to increase its prices commensurately with its increased costs, adversely affecting operating results.

Industry and Market Risks
Volatility of end markets that Eaton serves.
Eaton's segment revenues, operating results, and profitability have varied in the past and may vary from quarter to quarter in the future. Profitability can be negatively impacted by volatility in the end markets that Eaton serves. The Company has undertaken measures to reduce the impact of this volatility through diversification of the markets it serves and expansion of the geographic regions in which it operates. Future downturns in any of the markets could adversely affect revenues, operating results, and profitability.
Eaton's operating results depend in part on continued successful research, development, and marketing of new and/or improved products and services, and there can be no assurance that Eaton will continue to successfully introduce new products and services or maintain its present market positions.
The success of new and improved products and services depends on their initial and continued acceptance by Eaton's customers. The Company's businesses are affected, to varying degrees, by technological change and corresponding shifts in customer demand, which could result in unpredictable product transitions or shortened life cycles. Eaton may experience difficulties or delays in the research, development, production, or marketing of new products and services which may prevent Eaton from recouping or realizing a return on the investments required to bring new products and services to market. The Company's market positions may also be impacted by new entrants into Eaton's product or regional markets.
Legal and Regulatory Risks
Eaton's global operations subject it to economic risk as Eaton's results of operations may be adversely affected by changes in government legislation, regulations and policies, or currency fluctuations.
Operating globally subjects Eaton to changes in government regulations and policies in a large number of jurisdictions around the world, including those related to tariffs and trade barriers, investments, property ownership rights, taxation, data privacy, and exchange controls. Changes in the relative values of currencies occur from time to time and could affect Eaton's operating results. While the Company monitors exchange rate exposures and attempts to reduce these exposures through hedging activities, these risks could adversely affect operating results.
Further, existing free trade laws and regulations provide certain beneficial duties and tariffs for qualifying imports and exports, subject to compliance with applicable classification and other requirements. Changes in laws or policies governing the terms of foreign trade, and in particular increased trade restrictions, tariffs or taxes on imports from countries where we manufacture products, could have an impact on our business and financial results.
Eaton may be subject to risks relating to changes in its tax rates or exposure to additional income tax liabilities.
Eaton is subject to income taxes in many jurisdictions around the world. Income tax liabilities are subject to the allocation of income among various tax jurisdictions. The Company's effective tax rate could be affected materially by changes in the mix among earnings in countries with differing statutory tax rates, changes in the valuation allowance of deferred tax assets, or changes in tax legislation, regulations, and policies. The amount of income taxes paid is subject to ongoing audits by tax authorities in the countries in which Eaton operates. If these audits result in assessments different from amounts reserved, future financial results may include material unfavorable adjustments to the Company's tax liabilities.
Eaton may be unable to adequately protect its intellectual property rights, which could affect the Company's ability to compete.
Protecting Eaton's intellectual property rights is critical to its ability to compete and succeed. The Company owns a large number of patents and patent applications worldwide, as well as trademark and copyright registrations that are necessary, and contribute significantly, to the preservation of Eaton's competitive position in various markets. Although management believes that the loss or expiration of any single intellectual property right would not have a material effect on the results of operations or financial position of Eaton or its business segments, there can be no assurance that any one, or more, of these patents and other intellectual property will not be challenged, invalidated, or circumvented by third parties. Eaton enters into confidentiality and invention assignment agreements with the Company's employees, and into non-disclosure agreements with suppliers and appropriate customers, so as to limit access to and disclosure of proprietary information. These measures may not suffice to deter misappropriation or independent third party development of similar technologies.
Eaton is subject to litigation and environmental regulations that could adversely impact Eaton's businesses.
At any given time, Eaton may be subject to litigation, the disposition of which may have a material adverse effect on the Company's businesses, financial condition or results of operations. Information regarding current legal proceedings is presented in Note 10 and Note 11 of the Notes to the Consolidated Financial Statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and the Board of Directors of Eaton Corporation plc
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Eaton Corporation plc (“the Company”) as of December 31, 2021 and 2020, the related consolidated statements of income, comprehensive income, shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 23, 2022 expressed an unqualified opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit 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: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) 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.

| Unrecognized Income Tax Benefits
Description of the Matter | As discussed in Note 11 to the consolidated financial statements, the Company had gross unrecognized income tax benefits of $1,120 million related to its uncertain tax positions at December 31, 2021. Unrecognized income tax benefits are recorded under the two-step recognition and measurement principles when a tax position does not meet the more likely than not standard, or if a tax position meets the more likely than not standard, but the financial statement tax benefit is reduced as part of the measurement step. The balance of unrecognized income tax benefits is comprised of uncertain tax positions which meet the more likely than not standard, but the financial statement tax benefit has been reduced as part of measuring the tax position. Auditing management’s analysis of its uncertain tax positions and resulting unrecognized income tax benefits is complex as each tax position carries unique facts and circumstances that must be evaluated and ultimate resolution is dependent on uncontrollable factors such as the timing of finalizing resolutions of audit disputes through reaching settlement agreements or concluding litigation, or changes in law, and other factors.
How We Addressed the Matter in Our Audit | We obtained an understanding, evaluated the design and tested the operating effectiveness of management’s controls related to uncertain tax positions. For example, we tested controls over management’s application of the two-step recognition and measurement principles and management’s review of the inputs and resultant calculations of unrecognized income tax benefits, as well as the identification of uncertain tax positions. We also evaluated the Company’s assessment of its uncertain tax positions. Our audit procedures included evaluating management’s accounting policies and documentation to assess the appropriateness and consistency of the methods and assumptions used to develop its uncertain tax positions and related unrecognized income tax benefit amounts by jurisdiction. We also tested the completeness and accuracy of the underlying data used by the Company. For example, we compared the unrecognized income tax benefits recorded with similar positions in prior periods and assessed management’s consideration of current tax controversy and litigation and trends in similar positions challenged by tax authorities. We also assessed the historical accuracy of management’s estimates of its unrecognized income tax benefits with the resolution of those positions. In addition, we involved tax subject matter professionals to evaluate the application of relevant tax laws in the Company’s recognition determination. We have also evaluated the Company’s income tax disclosures in relation to these matters.

| Valuation of Customer Relationships Intangible Asset in the Acquisition of Tripp Lite
Description of the Matter | As discussed in Note 2 to the consolidated financial statements, during March 2021, the Company completed the acquisition of Tripp Lite for a total purchase price of approximately $1.65 billion, net of cash received. The acquisition was accounted for using the acquisition method of accounting. The consideration paid in the acquisition must be allocated to the acquired assets and liabilities assumed generally based on their fair value with the excess of the purchase price over those fair values allocated to goodwill. The estimates of the fair value of intangible assets were recorded in 2021 based upon third-party valuations, which resulted in the recognition of intangible assets totaling approximately $604 million, of which approximately $539 million related to customer relationships. Auditing the Company’s accounting for its acquisition of Tripp Lite was complex because the customer relationships intangible asset recognized was material to the consolidated financial statements and the estimate of fair value involved subjectivity. The subjectivity was primarily due to the sensitivity of the fair value to underlying assumptions about the future performance of the acquired business. The Company used a discounted cash flow model to measure the customer relationships intangible asset. The significant assumptions used to estimate the fair value of the customer relationships intangible asset included the discount rate and certain assumptions that form the basis of the forecasted results (e.g., revenue growth rates and future EBITDA margins). These significant assumptions are forward looking and could be affected by future economic and market conditions.
How We Addressed the Matter in Our Audit | We obtained an understanding, evaluated the design, and tested the operating effectiveness of the Company’s controls over its accounting for the acquisition of Tripp Lite, including recognition and measurement of the intangible assets acquired. For example, we tested controls over the recognition and measurement of the customer relationships intangible asset, including management’s review of the methods and significant assumptions used to develop the fair value estimate. To test the estimated fair value of the customer relationships intangible asset, we performed audit procedures that included, among others, evaluating the Company's selection of the valuation methodology, evaluating the methods and significant assumptions used by the Company's valuation specialist, and evaluating the completeness and accuracy of the underlying data supporting the significant assumptions and estimates. For example, when evaluating the assumptions related to the revenue growth rates and future EBITDA margins, we compared the assumptions to the past performance of Tripp Lite and expected industry trends and considered whether they were consistent with evidence obtained in other areas of the audit. We also performed sensitivity analyses to evaluate the changes in the fair value of the customer relationships intangible asset that would result from changes in the significant assumptions. We involved our EY valuation specialists to assist with our evaluation of the methodology used by the Company and certain significant assumptions included in the fair value estimate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and the Board of Directors of Eaton Corporation plc
Opinion on Internal Control Over Financial Reporting
We have audited Eaton Corporation plc’s (“the Company”) internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.
As indicated in the accompanying Management’s Report on Internal Control over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of the entities that were acquired during 2021 (as described in Note 2), which are included in the 2021 consolidated financial statements of the Company and constituted approximately 12% of total assets (inclusive of acquired intangible assets) as of December 31, 2021 and approximately 5% of net sales for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of the entities that were acquired during 2021.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2021 and 2020, the related consolidated statements of income, comprehensive income, shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2021, and the related notes and our report dated February 23, 2022 expressed an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
The management of Eaton Corporation plc ("Eaton") is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act rules 13a-15(f)).
Under the supervision and with the participation of Eaton's management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of the Company's internal control over financial reporting as of December 31, 2021. Our evaluation of internal control over financial reporting did not include the internal controls of the entities that were acquired during 2021 (as described in Note 2), which are included in the 2021 consolidated financial statements and constituted approximately 12% of total assets (inclusive of acquired intangible assets) as of December 31, 2021 and approximately 5% of net sales for the year then ended. In conducting this evaluation, we used the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (2013 Framework). Based on this evaluation under the framework referred to above, management concluded that the Company's internal control over financial reporting was effective as of December 31, 2021.
The independent registered public accounting firm Ernst & Young LLP has issued an audit report on the effectiveness of the Company's internal control over financial reporting as of December 31, 2021. This report is included herein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Amounts are in millions unless indicated otherwise (per share data assume dilution).
Note 1.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
General Information and Basis of Presentation
Eaton Corporation plc (Eaton or the Company) is an intelligent power management company dedicated to improving the quality of life and protecting the environment for people everywhere. We are guided by our commitment to do business right, to operate sustainably and to help our customers manage power – today and well into the future. By capitalizing on the global growth trends of electrification and digitalization, we're accelerating the planet's transition to renewable energy, helping to solve the world's most urgent power management challenges, and doing what's best for our stakeholders and all of society.
Founded in 1911, Eaton has been listed on the New York Stock Exchange for nearly a century. We reported revenues of $19.6 billion in 2021 and serve customers in more than 170 countries.
The consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States. Preparation of the consolidated financial statements requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and notes. Actual results could differ from these estimates. Management has evaluated subsequent events through the date the consolidated financial statements were filed with the Securities Exchange Commission.
The consolidated financial statements include the accounts of Eaton and all subsidiaries and other entities it controls. Intercompany transactions and balances have been eliminated. The equity method of accounting is used for investments in associate companies where the Company has significant influence and generally a 20% to 50% ownership interest. Equity investments are evaluated for impairment whenever events or circumstances indicate the book value of the investment exceeds fair value. An impairment would exist if there is an other-than-temporary decline in value. Investments in associate companies included in Other assets were $777 million and $680 million as of December 31, 2021 and December 31, 2020, respectively, and income from these investments is reported in Other expense - net. Eaton does not have off-balance sheet arrangements with unconsolidated entities.
Eaton's reporting currency is United States Dollars (USD). The functional currency for most subsidiaries is their local currency. Financial statements for these subsidiaries are translated at year-end exchange rates as to assets and liabilities and weighted-average exchange rates as to revenues and expenses. The resulting translation adjustments are recognized in Accumulated other comprehensive loss.
Certain prior year amounts have been reclassified to conform to the current year presentation.
Adoption of New Accounting Standard
Eaton adopted Accounting Standards Update 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, in the fourth quarter of 2021. This standard requires unbilled receivables (revenue recognized exceeds amount billed to customer) and deferred revenue liabilities (advanced payments and billings in excess of revenue recognized) from contracts with customers acquired as part of an acquisition of a business to be recognized and measured using revenue recognition accounting guidance, rather than at fair value. The adoption of the standard was applied to businesses acquired during 2021 and did not have a material impact on the consolidated financial statements.
LIBOR Transition
In July 2017, the United Kingdom’s Financial Cond uct Authority, which regulates the London Interbank Offered Rate (LIBOR), announced it intends to phase out LIBOR. The final publication of rates for certain USD LIBOR tenors is expected to be on June 30, 2023. Various parties, including government agencies, are seeking to identify alternative rates to replace LIBOR. The Company has established a cross-functional project team to evaluate the potential impacts of alternative rates as replacements to LIBOR in the Company’s contracts, which primarily include revolving credit facilities, fixed-to-floating interest rate swaps, and forward starting floating-to-fixed interest rate swaps. As of December 31, 2021, the Company’s $500 million 364-day revolving credit facility that will expire on October 3, 2022 and $2,000 million five-year revolving credit facility that will expire on October 4, 2026 both include a transition process from LIBOR to an alternative rate. The Company’s interest rate swaps are expected to settle prior to June 30, 2023. The Company continues to evaluate the potential impacts of the transition from LIBOR to alternative rates in its contracts and the transition is not expected to have a material impact on the consolidated financial statements.

Goodwill and Indefinite Life Intangible Assets
Goodwill is evaluated annually for impairment as of July 1 using either a quantitative or qualitative analysis. Additionally, goodwill is evaluated for impairment whenever an event occurs or circumstances change that would indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Goodwill is tested for impairment at the reporting unit level, and is based on the net assets for each reporting unit, including goodwill and intangible assets. The Company’s reporting units are equivalent to the reportable operating segments, except for the Aerospace segment which has two reporting units. Goodwill is assigned to each reporting unit, as this represents the lowest level that constitutes a business and is the level at which management regularly reviews the operating results. The Company performs a quantitative analysis using a discounted cash flow model and other valuation techniques, but may elect to perform a qualitative analysis.
The annual goodwill impairment test was performed using a qualitative analysis in 2021 and 2020, except for the eMobility reporting unit which used a quantitative analysis. A qualitative analysis is performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales and operating profit margins, discount rates, industry data, and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative analysis performed for each reporting unit. The results of the qualitative analyses did not indicate a need to perform quantitative analysis.
Goodwill impairment testing was also performed using quantitative analyses in 2020 for the Electrical Americas, Electrical Global, Hydraulics and Aerospace reporting units due to a reorganization of the Company’s businesses and in 2020 as a result of the Hydraulics business being classified as held for sale as discussed in Note 2. The Company used the relative fair value method to reallocate goodwill.
Quantitative analyses were performed by estimating the fair value for each reporting unit using a discounted cash flow model. The model includes estimates of future cash flows, future growth rates, terminal value amounts, and the applicable weighted-average cost of capital used to discount those estimated cash flows. The future cash flows were based on the Company's long-term operating plan and a terminal value was used to estimate the reporting unit's cash flows beyond the period covered by the operating plan. The weighted-average cost of capital is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. These analyses require the exercise of judgments, including judgments about appropriate discount rates, perpetual growth rates, revenue growth, and margin assumptions. Sensitivity analyses were performed around certain of these assumptions in order to assess the reasonableness of the assumptions and the resulting estimated fair values.
Based on these analyses performed in 2021 and 2020, the fair value of Eaton's reporting units continue to substantially exceed their respective carrying amounts and thus, no impairment exists.
Indefinite life intangible assets consist of certain trademarks. They are evaluated annually for impairment as of July 1 using either a quantitative or qualitative analysis to determine whether their fair values exceed their respective carrying amounts. Indefinite life intangible asset impairment testing for 2021 and 2020 was performed using a quantitative analysis. The Company determines the fair value of these assets using a royalty relief methodology similar to that employed when the associated assets were acquired, but using updated estimates of future sales, cash flows, and profitability. Additionally, indefinite life intangible assets are evaluated for impairment whenever an event occurs or circumstances change that would indicate that it is more likely than not that the asset is impaired. For 2021 and 2020, the fair value of indefinite lived intangible assets exceeded the respective carrying value.
For additional information about goodwill and other intangible assets, see Note 6.
Leases
The Company determines if an arrangement is a lease at inception. Operating lease assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. Lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. As most leases do not provide an implicit interest rate, Eaton uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. The length of a lease term includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. The Company made an accounting policy election to not recognize lease assets or liabilities for leases with a term of 12 months or less. Additionally, when accounting for leases, the Company combines payments for leased assets, related services and other components of a lease.

Other Long-Lived Assets
Depreciation and amortization for property, plant and equipment, and intangible assets subject to amortization, are generally computed by the straight-line method and included in Cost of products sold, Selling and administrative expense, and Research and development expense, as appropriate. The Company uses the following depreciation and amortization periods:

Category |  | Estimated useful life or amortization period
Buildings |  | Generally 40 years
Machinery and equipment |  | 3 - 10 years
Software |  | 5 - 15 years
Customer relationships, certain trademarks, and patents and technology |  | Weighted-average of 18 years

Other long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Upon indications of impairment, assets and liabilities are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The asset group would be considered impaired when the estimated future net undiscounted cash flows generated by the asset group are less than its carrying value. Determining asset groups and underlying cash flows requires the use of significant judgment.
Retirement Benefits Plans
For the principal pension plans in the United States, Canada, Puerto Rico, and the United Kingdom, the Company uses a market-related value of plan assets to calculate the expected return on assets used to determine net periodic benefit costs. The market-related value of plan assets is a calculated value that recognizes changes in the fair value of plan assets over a five year period. All other plans use fair value of plan assets.
Net actuarial gains or losses are amortized to expense on a plan-by-plan basis when they exceed the accounting corridor. The Company’s corridors are set at either 8% or 10%, depending on the plan, of the greater of the plan assets or benefit obligations. Gains or losses outside of the corridor are subject to amortization over an average employee future service period that differs by plan. If most or all of the plan’s participants are no longer actively accruing benefits, the average life expectancy is used. The amortization periods on a weighted average basis for United States and Non-United States pension plans are approximately 23 years and 10 years, respectively. The amortization period for other postretirement benefits plans is 7 years.
Asset Retirement Obligations
A conditional asset retirement obligation is recognized at fair value when incurred if the fair value of the liability can be reasonably estimated. Uncertainty about the timing or method of settlement of a conditional asset retirement obligation would be considered in the measurement of the liability when sufficient information exists. Eaton believes that for substantially all of its asset retirement obligations, there is an indeterminate settlement date because the range of time over which the Company may settle the obligation is unknown or cannot be estimated. A liability for these obligations will be recognized when sufficient information is available to estimate fair value.
Income Taxes
Deferred income tax assets and liabilities are determined based on the difference between the financial statement and tax basis of the respective assets and liabilities, using enacted tax rates in effect for the year when the differences are expected to reverse. Deferred income tax assets are recognized for income tax loss carryforwards and income tax credit carryforwards. Judgment is required in determining and evaluating income tax provisions and valuation allowances for deferred income tax assets. Eaton recognizes an income tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. Eaton evaluates and adjusts these accruals based on changing facts and circumstances. Eaton recognizes interest and penalties related to unrecognized income tax benefits in the provision for income tax expense. Eaton's policy is to recognize income tax effects from accumulated other comprehensive income when individual units of account are sold, terminated, or extinguished. For additional information about income taxes, see Note 11.

Derivative Financial Instruments and Hedging Activities
Eaton uses derivative financial instruments to manage the exposure to the volatility in raw material costs, currency, and interest rates on certain debt. These instruments are marked to fair value in the accompanying Consolidated Balance Sheets. Changes in the fair value of derivative assets or liabilities (i.e., gains or losses) are recognized depending upon the type of hedging relationship and whether an instrument has been designated as a hedge. For those instruments that qualify for hedge accounting, Eaton designates the hedging instrument, based upon the exposure being hedged, as a cash flow hedge, a fair value hedge, or a hedge of a net investment in a foreign operation. Changes in fair value of these instruments that do not qualify for hedge accounting are recognized immediately in net income. See Note 15 for additional information about hedges and derivative financial instruments.
Note 2.ACQUISITIONS AND DIVESTITURES OF BUSINESSES

Table of Contents
Goodwill is calculated as the excess of the consideration transferred over the fair value of net assets recognized and represents the anticipated synergies of acquiring Souriau-Sunbank. Goodwill recognized as a result of the acquisition is not deductible for tax purposes. The estimated fair values of the customer relationships and technology intangible assets were $250 million and $95 million, respectively. The Company generally determines the fair value of intangible assets acquired using third-party valuations that are prepared using discounted cash flow models that rely on the Company's estimates. These estimates require judgment of future revenue growth rates, future margins, and the applicable weighted-average cost of capital used to discount those estimated cash flows. The estimated weighted-average useful lives was 20 years for customer relationships and 15 years for technology intangible assets. See Note 6 for additional information about goodwill and other intangible assets.

Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the anticipated synergies of acquiring Tripp Lite. Goodwill recognized as a result of the acquisition is not deductible for tax purposes. The adjusted preliminary estimated fair values of the customer relationships, trademarks and technology intangible assets of $539 million, $33 million and $32 million, respectively, were determined using either the relief-from-royalty model or the multi-period excess earnings model, which are discounted cash flow models that rely on the Company's estimates. These estimates require judgment of future revenue growth rates, future margins, and the applicable weighted-average cost of capital used to discount those estimated cash flows. The weighted-average cost of capital is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. The estimated useful lives for customer relationships, trademarks and technology intangible assets were 20 years, 15 years, and 5 years, respectively. See Note 6 for additional information about goodwill and other intangible assets.

Acquisition of a 50% stake in Jiangsu YiNeng Electric's busway business
On June 25, 2021, Eaton acquired a 50 percent stake in Jiangsu YiNeng Electric's busway business, which manufactures and markets busway products in China. Eaton accounts for this investment on the equity method of accounting and is reported within the Electrical Global business segment.
Sale of Hydraulics business
On January 21, 2020, Eaton entered into an agreement to sell its Hydraulics business to Danfoss A/S, a Danish industrial company. The Hydraulics business sold hydraulics components, systems, and services for industrial and mobile equipment. The business had sales of $1.8 billion in 2020 and $1.3 billion in 2021 through the date of the sale.
During the first quarter of 2020, the Company determined the Hydraulics business met the criteria to be classified as held for sale. Therefore, assets and liabilities of the business have been presented as held for sale in the Consolidated Balance Sheet as of December 31, 2020. Assets and liabilities classified as held for sale are measured at the lower of carrying value or fair value less costs to sell.
No write-down was required as fair value of the Hydraulics business assets less the costs to sell exceed their respective carrying value. Depreciation and amortization expense was not recorded for the period in which Other long-lived assets were classified as held for sale.

Table of Contents
The Company used the relative fair value method to allocate goodwill to the Hydraulics business. The fair value of the Hydraulics business was estimated based on a combination of the price paid to Eaton by Danfoss A/S and a discounted cash flow model. The model includes estimates of future cash flows, future growth rates, terminal value amounts, and the applicable weighted-average cost of capital used to discount those estimated cash flows. The weighted-average cost of capital is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. These analyses require the exercise of judgments, including judgments about appropriate discount rates, perpetual growth rates, revenue growth, and margin assumptions.
The assets and liabilities classified as held for sale for the Hydraulics business on the December 31, 2020 Consolidated Balance Sheet are as follows:

(In millions) | December 31, 2020 |  |
Accounts receivable - net | $ | 345 |  |  |
Inventory | 369 |  |  |
Prepaid expenses and other current assets | 18 |  |  |
Net property, plant and equipment | 504 |  |  |
Goodwill | 920 |  |  |
Other intangible assets | 248 |  |  |
Operating lease assets | 61 |  |  |
Deferred income taxes | 6 |  |  |
Other noncurrent assets | 16 |  |  |
Assets held for sale - current | $ | 2,487 |  |  |
Accounts payable | $ | 241 |  |  |
Accrued compensation | 26 |  |  |
Other current liabilities | 101 |  |  |
Pension liabilities | 60 |  |  |
Operating lease liabilities | 35 |  |  |
Deferred income taxes | 3 |  |  |
Other noncurrent liabilities | 2 |  |  |
Liabilities held for sale - current | $ | 468 |  |  |

On August 2, 2021, Eaton completed the sale of the Hydraulics business to Danfoss A/S. As a result of the sale, the Company received $3.1 billion, net of cash sold, and recognized a pre-tax gain of $617 million, subject to post-closing adjustments to be negotiated with Danfoss A/S. The Hydraulics business did not meet the criteria to be classified as discontinued operations as the sale does not represent a strategic shift that will have a major effect on the Company's operations.
Acquisition of Royal Power Solutions
On January 5, 2022, Eaton acquired Royal Power Solutions for $600 million. Royal Power Solutions is a U.S. based manufacturer of high-precision electrical connectivity components used in electric vehicle, energy management, industrial and mobility markets.

Note 3. REVENUE RECOGNITION
Sales are recognized when obligations under the terms of the contract are satisfied and control of promised goods or services have transferred to our customers. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services. Sales are measured at the amount of consideration the Company expects to be paid in exchange for these products or services.
The majority of the Company’s sales agreements contain performance obligations satisfied at a point in time when title and risk and rewards of ownership have transferred to the customer. Sales recognized over time are less than 5% of Eaton’s Consolidated Net Sales. Sales recognized over time are generally accounted for using an input measure to determine progress completed at the end of the period. Sales for service contracts generally are recognized as the services are provided. For agreements with multiple performance obligations, judgment is required to determine whether performance obligations specified in these agreements are distinct and should be accounted for as separate revenue transactions for recognition purposes. In these types of agreements, we generally allocate sales price to each distinct obligation based on the price of each item sold in separate transactions.
Due to the nature of the work required to be performed for obligations recognized over time, Eaton estimates total costs by contract. The estimate of total costs are subject to judgment. Estimated amounts are included in the recognized sales price to the extent it is not probable that a significant reversal of cumulative sales will occur. Additionally, contracts can be modified to account for changes in contract specifications, requirements or sale price. The effect of a contract modification on the sales price or adjustments to the measure of completion under the input method are recognized as adjustments to revenue on a cumulative catch-up basis.
Payment terms vary by the type and location of the customer and the products or services offered. Generally, the time between when revenue is recognized and when payment is due is not significant. Eaton does not evaluate whether the selling price includes a financing interest component for contracts that are less than a year. Sales, value added, and other taxes collected concurrent with revenue are excluded from sales. Shipping and handling costs are treated as fulfillment costs and are included in Cost of products sold.
Eaton records reductions to sales for returns, and customer and distributor incentives, primarily comprised of rebates, at the time of the initial sale. Rebates are estimated based on sales terms, historical experience, trend analysis, and projected market conditions in the various markets served. The rebate programs offered vary across businesses due to the numerous markets Eaton serves, but the most common incentives relate to amounts paid or credited to customers for achieving defined volume levels. Returns are estimated at the time of the sale primarily based on historical experience and are recorded gross on the Consolidated Balance Sheet.
Sales commissions are expensed when the amortization period is less than a year and are generally not capitalized as they are typically earned at the completion of the contract when the customer is invoiced or when the customer pays Eaton.
Sales of products and services varies by segment and are discussed in Note 17.
In the Electrical Americas segment, sales contracts are primarily for electrical components, industrial components, power distribution and assemblies, residential products, single phase power quality and connectivity, three phase power quality, wiring devices, circuit protection, utility power distribution, power reliability equipment, and services that are primarily produced and sold in North and South America. The majority of the sales in this segment contain performance obligations satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility. However, certain power distribution and power quality services are recognized over time.
In the Electrical Global segment, sales contracts are primarily for electrical components, industrial components, power distribution and assemblies, single phase and three phase power quality, and services that are primarily produced and sold outside of North and South America, as well as hazardous duty electrical equipment, emergency lighting, fire detection, intrinsically safe explosion-proof instrumentation, and structural support systems that are produced and sold globally. The majority of the sales contracts in this segment contain performance obligations satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility. However, certain power distribution and power quality services are recognized over time.
In the Aerospace segment, sales contracts are primarily for aerospace fuel, hydraulics, and pneumatic systems for commercial and military use, as well as filtration systems for industrial applications. These sales contracts are primarily based on a customer’s purchase order, and frequently covered by terms and conditions included in a long-term agreement. In this segment, performance obligations are generally satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility. Our military contracts are primarily fixed-price contracts that are not subject to performance-based payments or progress payments from the customer.

Table of Contents
Many of the products and services in power distribution and power quality services in the Electrical Americas and Electrical Global business segments and contracts to develop new products that are fully funded by customers in the Aerospace business segment meet the definition of continuous transfer of control to customers and are recognized over time. These products are engineered to a customer’s design specifications, have no alternative use to Eaton, and are controlled by the customer as evidenced by the customer’s contractual ownership of the work in process or our right to payment for work performed to date plus a reasonable margin. As control is transferring over time, sales are recognized based on the extent of progress towards completion of the obligation. Eaton generally uses an input method to determine the progress completed and sales are recorded proportionally as costs are incurred. Incurred costs represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer.
In the Hydraulics segment, sales contracts were primarily for hydraulic components and systems for industrial and mobile equipment. These sales contracts were primarily based on a customer’s purchase order. In this segment, performance obligations were generally satisfied at a point in time when we ship the product from our facility.
In the Vehicle segment, sales contracts are primarily for drivetrains, powertrain systems and critical components that reduce emissions and improve fuel economy, stability, performance, and safety of cars, light trucks, and commercial vehicles. These sales contracts are primarily based on a customer’s purchase order or a blanket purchase order subject to firm releases, frequently covered by terms and conditions included in a master supply agreement. In this segment, performance obligations are generally satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility.
In the eMobility segment, sales contracts are primarily for mechanical, electrical, and electronic components and systems that improve the power management and performance of both on-road and off-road vehicles. These sales contracts are primarily based on a customer’s purchase order. In this segment, performance obligations are generally satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility.
In limited circumstances, primarily in the Electrical and Vehicle segments, Eaton sells separately-priced warranties that extend the warranty coverage beyond the standard coverage offered on specific products. Sales for these separately-priced warranties are recorded based on their stand-alone selling price and are recognized as revenue over the length of the warranty period.

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (revenue recognized exceeds amount billed to the customer), and deferred revenue (advance payments and billings in excess of revenue recognized). Accounts receivables from customers were $2,896 million and $2,539 million at December 31, 2021 and December 31, 2020, respectively. Amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals or upon achievement of contractual milestones. These assets and liabilities are reported on the Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period. Unbilled receivables were $187 million and $90 million at December 31, 2021 and December 31, 2020, respectively, and are recorded in Prepaid expenses and other current assets. The increase in unbilled receivables reflects higher revenue recognized from increased business activity in 2021 and the addition of unbilled receivables from acquisitions.

A significant portion of open orders placed with Eaton are by original equipment manufacturers or distributors. These open orders are not considered firm as they have been historically subject to releases by customers. In measuring backlog of unsatisfied or partially satisfied obligations, only the amount of orders to which customers are firmly committed are included. Using this criterion, total backlog at December 31, 2021 was approximately $7.7 billion. At December 31, 2021, approximately 87% of this backlog is targeted for delivery to customers in the next twelve months and the rest thereafter.
Note 4. CREDIT LOSSES FOR RECEIVABLES
Receivables are exposed to credit risk based on the customers' ability to pay which is influenced by, among other factors, their financial liquidity position. Eaton's receivables are generally short-term in nature with a majority outstanding less than 90 days.
Eaton performs ongoing credit evaluation of its customers and maintains sufficient allowances for potential credit losses. The Company evaluates the collectability of its receivables based on the length of time the receivable is past due, and any anticipated future write-off based on historic experience adjusted for market conditions. The Company's segments, supported by our global credit department, perform the credit evaluation and monitoring process to estimate and manage credit risk. The process includes an evaluation of credit losses for both the overall segment receivable and specific customer balances. The process also includes review of customer financial information and credit ratings, approval and monitoring of customer credit limits, and an assessment of market conditions. The Company may also require prepayment from customers to mitigate credit risk. Receivable balances are written off against an allowance for credit losses after a final determination of collectability has been made.
Accounts receivable are net of an allowance for credit losses of $42 million and $48 million at December 31, 2021 and 2020. The change in the allowance for credit losses includes expense and net write-offs, none of which are significant.

During 2020, the Company announced it was freezing its United States pension plans for its non-union employees. The freeze was effective January 1, 2021 for non-union U.S. employees whose retirement benefit was determined under a cash balance formula and is effective January 1, 2026 for non-union U.S. employees whose retirement benefit is determined under a final average pay formula.
Actuarial gains related to changes in the United States and Non-United States benefit obligations in 2021 of $82 million and $143 million, respectively, were primarily due to increases in the discount rates used to measure the obligations. Actuarial losses related to changes in the United States and Non-United States benefit obligations in 2020 of $223 million and $217 million, respectively, were primarily due to decreases in the discount rates used to measure the obligations, partially offset by curtailment gains related to amendments to freeze the Company's United States pension plans for its non-union employees.

Retirement Benefits Plans Assumptions
In 2019, 2020, and 2021, for purposes of determining liabilities related to the majority of its plans in the United States, the Company used mortality tables that are based on the Company's own experience and generational improvement scales that are based on MP-2019, MP-2020, and MP-2021, respectively.
To estimate the service and interest cost components of net periodic benefit cost for the vast majority of its defined benefits pension and other postretirement benefits plans, the Company used a spot rate approach by applying the specific spot rates along the yield curve used to measure the benefit obligation at the beginning of the period to the relevant projected cash flows.

Pension Plan Assets
Investment policies and strategies are developed on a country and plan specific basis. The United States plans, representing 62% of worldwide pension assets, and the United Kingdom plans representing 29% of worldwide pension assets, are invested primarily for growth, as the majority of the assets are in plans with active participants and ongoing accruals. In general, the plans are primarily allocated to diversified global equities, primarily through index funds in the form of common collective and other trusts. The United States plans' target allocation is 19% United States equities, 19% non-United States equities, 6% real estate (primarily equity of real estate investment trusts), 47% debt securities and 9% other, including private equity, private debt and cash equivalents. The United Kingdom plans' target asset allocations are 44% equities and the remainder in debt securities, cash equivalents and real estate investments. The equity risk for the plans is managed through broad geographic diversification and diversification across industries and levels of market capitalization. The majority of debt allocations for these plans are longer duration government and corporate debt. The United States, United Kingdom and Canada pension plans are authorized to use derivatives to achieve more economically desired market exposures through the use of futures, swaps and options to gain or hedge exposures.
Fair Value Measurements
Financial instruments included in pension and other postretirement benefits plan assets are categorized into a fair value hierarchy of three levels, based on the degree of subjectivity inherent in the valuation methodology are as follows:
Level 1 -Quoted prices (unadjusted) for identical assets in active markets.
Level 2 -Quoted prices for similar assets in active markets, and inputs that are observable for the asset, either directly or indirectly, for substantially the full term of the financial instrument.
Level 3 -Unobservable prices or inputs.
Certain investments that are measured at fair value using the net asset value per share practical expedient have not been categorized in the fair value hierarchy and are being presented in the tables to permit a reconciliation to total plan assets.

Valuation Methodologies
Following is a description of the valuation methodologies used for pension and other postretirement benefits plan assets measured at fair value. There have been no changes in the methodologies used at December 31, 2021 and 2020.
Common collective and other trusts - Valued at the net unit value of units held by the trust at year end. The unit value is determined by the total value of fund assets divided by the total number of units of the fund owned. The equity investments in collective trusts are predominantly in index funds for which the underlying securities are actively traded in public markets based upon readily measurable prices. The investments in other trusts are predominantly in exchange traded funds for which the underlying securities are actively traded in public markets based upon readily measurable prices. Common collective and other trusts measured at fair value using the net asset value per share practical expedient have not been categorized in the fair value hierarchy and are being presented in the tables above to permit a reconciliation of the fair value hierarchy to the total plan assets.
Fixed income securities - These securities consist of publicly traded United States and non-United States fixed interest obligations (principally corporate and government bonds and debentures). The fair value of corporate and government debt securities is determined through third-party pricing models that consider various assumptions, including time value, yield curves, credit ratings, and current market prices. The Company verifies the results of trustees or custodians and evaluates the pricing classification of these securities by performing analyses using other third-party sources.
Equity securities - These securities consist of comingled funds and direct investments consisting of the stock of publicly traded companies. Such investments are valued based on the closing price reported in an active market on which the individual securities are traded.
United States treasuries - Valued at the closing price of each security.
Bank loans - These securities consist of senior secured term loans of publicly traded and privately held United States and non-United States floating rate obligations (principally corporations of non-investment grade rating). The fair value is determined through third-party pricing models that primarily utilize dealer quoted current market prices. The Company verifies the results of trustees or custodians and evaluates the pricing classification of these securities by performing analyses using other third-party sources.

Table of Contents
Real estate - Consists of direct investments in the stock of publicly traded companies and investments in pooled funds that invest directly in real estate. The publicly traded companies are valued based on the closing price reported in an active market on which the individual securities are traded and as such are classified as Level 1. The pooled funds rely on appraisal-based valuations and as such are classified as Level 3.
Cash equivalents - Primarily certificates of deposit, commercial paper, and repurchase agreements.
Exchange traded funds - Valued at the closing price of the exchange traded fund's shares.
Money market funds - Money market funds measured at fair value using the net asset value per share practical expedient have not been categorized in the fair value hierarchy and are being presented in the tables above to permit a reconciliation of the fair value hierarchy to the total plan assets.
Other - These assets consist of private equity, private debt, insurance contracts primarily for international plans, futures contracts, and over-the-counter options. Investments in private equity and private debt are valued at net asset value or estimated fair value based on quarterly financial information received from the investment advisor, third party appraisal or general partner. These estimates incorporate factors such as contributions and distributions, market transactions, market comparables and performance multiples. Futures contracts and options are valued based on the closing prices of contracts or indices as available using third-party sources.
For additional information regarding fair value measurements, see Note 14.

Note 10. COMMITMENTS AND CONTINGENCIES
Legal Contingencies
Eaton is subject to a broad range of claims, administrative and legal proceedings such as lawsuits that relate to contractual allegations and indemnity claims, tax audits, patent infringement, personal injuries, antitrust matters, and employment-related matters. Eaton is also subject to asbestos claims from historic products which may have contained asbestos. Insurance may cover some of the costs associated with these claims and proceedings. Although it is not possible to predict with certainty the outcome or cost of these matters, the Company believes they will not have a material adverse effect on the consolidated financial statements.
Environmental Contingencies
Eaton has established policies to ensure that its operations are conducted in keeping with good corporate citizenship and with a positive commitment to the protection of the natural and workplace environments. The Company requires that its businesses be certified to ISO 14001, an international standard for environmental management systems. The Company routinely reviews EHS performance at each of its manufacturing facilities and continuously strives to improve its environmental footprint, including carbon, waste, water and related operational profiles consistent with our sustainability goals.
Eaton is involved in remedial response and voluntary environmental remediation at a number of sites, including certain of its currently-owned or formerly-owned plants. The Company has also been named a potentially responsible party under the United States federal Superfund law, or the state equivalents thereof, at a number of disposal sites. The Company became involved in these sites as a result of government action or in connection with business acquisitions. At the end of 2021, the Company was involved with a total of 115 sites worldwide, including the Superfund sites mentioned above, with none of these sites being individually significant to the Company.
Remediation activities, generally involving soil and/or groundwater contamination, include pre-cleanup activities such as fact finding and investigation, risk assessment, feasibility study, design and action planning, performance (where actions may range from monitoring, to removal of contaminants, to installation of longer-term remediation systems), and operation and maintenance of a remediation system. The extent of expected remediation activities and costs varies by site. A number of factors affect the cost of environmental remediation, including the number of parties involved at a particular site, the determination of the extent of contamination, the length of time the remediation may require, the complexity of environmental regulations, and the continuing advancement of remediation technology. Taking these factors into account, Eaton has estimated the costs of remediation, which will be paid over a period of years. The Company accrues an amount on an undiscounted basis, consistent with the estimates of these costs, when it is probable that a liability has been incurred. Actual results may differ from these estimates. At December 31, 2021 and 2020, the Company had an accrual totaling $99 million and $103 million, respectively, for these costs.
Based upon Eaton's analysis and subject to the difficulty in estimating these future costs, the Company expects that any sum it may be required to pay in connection with environmental matters is not reasonably possible to exceed the recorded liability by an amount that would have a material effect on its financial position, results of operations or cash flows.
Warranty Accruals
Product warranty accruals are established at the time the related sale is recognized through a charge to Cost of products sold. Warranty accrual estimates are based primarily on historical warranty claim experience and specific customer contracts. Provisions for warranty accruals are comprised of basic warranties for products sold, as well as accruals for product recalls and other events when they are known and estimable. A summary of the current and long-term warranty accruals is as follows:

During 2021, income tax expense of $750 million was recognized (an effective tax rate of 25.9%) compared to income tax expense of $331 million in 2020 (an effective tax rate of 19.0%) and income tax expense of $378 million in 2019 (an effective tax rate of 14.6%). The increase in the effective tax rate from 19% in 2020 to 25.9% in 2021 was primarily due to the tax expense on the gain from the sale of the Hydraulics business in 2021 discussed in Note 2. The increase in the effective tax rate from 14.6% in 2019 to 19.0% in 2020 was primarily due to the tax expense on the gain from the sale of the Lighting business in 2020 discussed in Note 2, partially offset by a tax benefit on the restructuring charges discussed in Note 16.

No provision has been made for income taxes on undistributed earnings of foreign subsidiaries of approximately $29.9 billion at December 31, 2021, since it is the Company's intention to indefinitely reinvest undistributed earnings of its foreign subsidiaries. The Company expects to deploy capital to those markets which offer particularly attractive growth opportunities. The cash that is permanently reinvested is typically used to expand operations either organically or through acquisitions. It is not practicable to estimate the additional income taxes and applicable withholding taxes that would be payable on the remittance of such undistributed earnings.

In 2021, the Company recorded an increase of $1.5 billion in its deferred tax assets for foreign income tax loss carryforwards related to a tax deductible statutory adjustment in Luxembourg. The Company also recorded a corresponding increase in its valuation allowance for income tax loss carryforwards, since it does not believe that it is more likely than not that the net operating loss is realizable, resulting in no impact to the Consolidated Statements of Income.

Recoverability of Deferred Income Tax Assets
Eaton is subject to the income tax laws in the jurisdictions in which it operates. In order to determine its income tax provision for financial statement purposes, Eaton must make significant estimates and judgments about its business operations in these jurisdictions. These estimates and judgments are also used in determining the deferred income tax assets and liabilities that have been recognized for differences between the financial statement and income tax basis of assets and liabilities, and income tax loss carryforwards and income tax credit carryforwards.
Management evaluates the realizability of deferred income tax assets for each of the jurisdictions in which it operates. If the Company experiences cumulative pre-tax income in a particular jurisdiction in the three-year period including the current and prior two years, management normally concludes that the deferred income tax assets will more likely than not be realizable and no valuation allowance is recognized, unless known or planned operating developments, or changes in tax laws, would lead management to conclude otherwise. However, if the Company experiences cumulative pre-tax losses in a particular jurisdiction in the three-year period including the current and prior two years, management then considers a series of factors in the determination of whether the deferred income tax assets can be realized. These factors include historical operating results, known or planned operating developments, the period of time over which certain temporary differences will reverse, consideration of the utilization of certain deferred income tax liabilities, tax law carryback capability in the particular country, prudent and feasible tax planning strategies, changes in tax laws, and estimates of future earnings and taxable income using the same assumptions as those used for the Company's goodwill and other impairment testing. After evaluation of these factors, if the deferred income tax assets are expected to be realized within the tax carryforward period allowed for that specific country, management would conclude that no valuation allowance would be required. To the extent that the deferred income tax assets exceed the amount that is expected to be realized within the tax carryforward period for a particular jurisdiction, management would establish a valuation allowance.
Applying the above methodology, valuation allowances have been established for certain deferred income tax assets to the extent they are not expected to be realized within the particular tax carryforward period.

Eaton recognizes an income tax benefit from an uncertain tax position only if it is more likely than not that the benefit would be sustained upon examination by taxing authorities, based on the technical merits of the position. The Company evaluates and adjusts the amount of unrecognized income tax benefits based on changes in facts and circumstances. The Company does not enter into any of the United States Internal Revenue Service (IRS) Listed Transactions as set forth in Treasury Regulation 1.6011-4.
If all unrecognized income tax benefits were recognized, the net impact on the provision for income tax expense would be $755 million.
As of December 31, 2021 and 2020, Eaton had accrued approximately $128 million and $110 million, respectively, for the payment of worldwide interest and penalties, which are not included in the table of unrecognized income tax benefits above. Eaton recognizes interest and penalties related to unrecognized income tax benefits in the provision for income tax expense.
The resolution of the majority of Eaton's unrecognized income tax benefits is dependent upon uncontrollable factors such as the timing of finalizing resolutions of audit disputes through reaching settlement agreements or concluding litigation, or changes in law. Therefore, for the majority of Eaton’s unrecognized income tax benefits, it is not reasonably possible to estimate the increase or decrease in the next 12 months. For each of the unrecognized income tax benefits where it is possible to estimate the increase or decrease in the balance within the next 12 months, the Company does not anticipate any significant change.
The Company believes that the final resolution of all the assessments discussed below will not have a material impact on its consolidated financial statements. The ultimate outcome of these matters cannot be predicted with certainty given the complex nature of tax controversies. Should the ultimate outcome of any one of these matters deviate from our reasonable expectations, they may have a material adverse impact on the Company’s consolidated financial statements. However, Eaton believes that its interpretations of tax laws and application of tax laws to its facts are correct, and that its accrual of unrecognized income tax benefits is appropriate with respect to these matters.
Eaton or its subsidiaries file income tax returns in Ireland and many countries around the world. With only a few exceptions, including the tax years in Brazil and the United States discussed below, Eaton and its subsidiaries are no longer subject to examinations for years before 2014.

Brazil Tax Years 2005-2012
During 2010, the Company received a tax assessment, which included interest and penalties, in Brazil for the tax years 2005 through 2008 that relates to the amortization of certain goodwill generated from the acquisition of third-party businesses and corporate reorganizations. In 2018, the Company received an unfavorable result at the final tax administrative appeals level. In August 2021, the Company was notified of a recalculation from an original alleged tax deficiency of $23 million plus $65 million of interest and penalties to a revised alleged tax deficiency of $30 million plus $97 million of interest and penalties (translated at the December 31, 2021 exchange rate). During 2014, the Company received a tax assessment, which included interest and penalties, for the 2009 through 2012 tax years (primarily relating to the same issues concerning the 2005 through 2008 tax years). In November 2019, the Company received an unfavorable result at the final tax administrative appeals level, resulting in an alleged tax deficiency of $25 million plus $90 million of interest and penalties (translated at the December 31, 2021 exchange rate). The Company is challenging both of the assessments in the judicial system. Challenges in the judicial system are expected to take several years to resolve and require provision of certain assets as security for the alleged deficiencies. As of December 31, 2021, the Company pledged Brazilian real estate assets with net book value of $18 million and provided additional security in the form of three separate bonds totaling $96 million and a cash deposit of $17 million (translated at the December 31, 2021 exchange rate).
United States Tax Disputes
The United States Internal Revenue Service (IRS) typically audits large corporate taxpayers on a continuous basis, generally resulting in many open tax years if there are disputed tax positions upon completion of the audits. The IRS has completed its examination of the consolidated income tax returns of the Company’s United States subsidiaries (Eaton US) for 2005 through 2016 and the statuses of the various tax years are discussed below. The IRS has challenged certain tax positions of Eaton US, and the Company is attempting to resolve those issues in litigation and the IRS administrative process, as described in more detail below. The IRS is currently examining tax years 2017 through 2019, and the statute of limitations for those years is open until December 31, 2024. Tax years 2020 and later are subject to future examination by the IRS. Income tax returns of states and localities within the United States will be reopened to the extent of United States federal income tax adjustments, if any, going back to 2005 when those audit years are finalized. The Eaton US tax positions challenged by the IRS are items that recur beyond the tax years for which the IRS has proposed adjustments. Eaton believes that its interpretations of tax laws and application of tax laws to its facts are correct. However, if there is a final unfavorable resolution of any of the issues discussed below, it may have a material adverse impact on the Company’s consolidated financial statements.
U.S. Tax Years 2005-2006
In 2011, the IRS issued a Statutory Notice of Deficiency for Eaton US for the 2005 and 2006 tax years (the 2005-06 Notice), which Eaton US contested in United States Tax Court. The 2005-06 Notice proposed assessments of $75 million in additional taxes plus $52 million in penalties related primarily to transfer pricing adjustments for products manufactured in the Company's facilities in Puerto Rico and the Dominican Republic and sold to affiliated companies located in the United States. Eaton US has set its transfer prices for products sold between these affiliates at the same prices that Eaton US sells such products to third parties as required by two successive Advance Pricing Agreements (APAs) Eaton US entered into with the IRS that governed the 2005-2010 tax years. Eaton US has continued to apply the APA pricing methodology for 2011 through the current reporting period. Immediately prior to the 2005-06 Notice being issued, the IRS sent a letter stating that it was retrospectively canceling the APAs. The case in Tax Court involved whether the IRS improperly cancelled the APAs. On July 26, 2017, the Tax Court issued a ruling in which it agreed with Eaton US that the IRS must abide by the terms of the APAs for the tax years 2005-2006. The Tax Court’s ruling on the APAs did not have a material impact on Eaton’s consolidated financial statements. On May 24, 2021, the IRS filed a notice to appeal the Tax Court’s ruling to the United States Sixth Circuit Court of Appeals, and the appellate process is anticipated to be ongoing in 2022. Tax years 2005 and 2006 remain open until this matter is resolved.

Table of Contents
U.S. Tax Years 2007-2010
In 2014, the IRS issued a Statutory Notice of Deficiency for Eaton US for the 2007 through 2010 tax years (the 2007-10 Notice), which Eaton US contested in Tax Court. The 2007-10 Notice proposed assessments of $190 million in additional taxes plus $72 million in penalties, net of agreed credits and deductions. The proposed assessments pertain to: (i) the same transfer pricing issues and APA for which the Tax Court has issued its ruling during 2017 as noted above; and (ii) the separate proposed assessment noted below. The Company believes that the Tax Court’s ruling for tax years 2005-2006 will also be applicable to the 2007-2010 years. Following the issuance of the Tax Court’s ruling, Eaton and the IRS recognized that the ruling on the enforceability of the APA did not address a secondary issue regarding the transfer pricing for a certain royalty paid from 2006-2010. Eaton US reported a consistent royalty rate for 2006-2010. The IRS has agreed to the royalty rate as reported by Eaton US in 2006. Although the IRS has not proposed an alternative rate, it has not agreed to apply the same royalty rate in the 2007-2010 years.
The 2007-10 Notice also includes a separate proposed assessment involving the recognition of income for several of Eaton US’s controlled foreign corporations. The Company believes that the proposed assessment is without merit and contested the matter in Tax Court. In October 2017, Eaton and the IRS both moved for partial summary judgment on this issue. On February 25, 2019, the Tax Court granted the IRS’s motion for partial summary judgment and denied Eaton’s. The Company intends to appeal the Tax Court’s partial summary judgment decision to the United States Sixth Circuit Court of Appeals. The total potential impact of the Tax Court's partial summary judgment decision on the controlled foreign corporation income recognition issue is not estimable until all matters in the open tax years have been resolved.
U.S. Tax Years 2011-2013
In 2018, the IRS completed its examination of Eaton US for tax years 2011 through 2013 and has proposed adjustments, including: (i) transfer pricing adjustments similar to those proposed in the 2005-06 and 2007-10 Notices for products manufactured in the Company’s facilities in Puerto Rico and the Dominican Republic and sold to affiliated companies located in the U.S.; (ii) adjustments involving the recognition of income for several of Eaton US’s controlled foreign corporations, which is the same issue included in the 2007-10 Notice described above and subject to litigation in Tax Court; (iii) transfer pricing adjustments for products manufactured in one of the Company’s facilities in Mexico and sold to affiliated companies located in the U.S.; and (iv) adjustments challenging the appropriate interest rate on intercompany debt and amount of intercompany fees charged for financial guarantees on external debt. The Company is attempting to resolve certain of these issues in administrative appeals. However, if acceptable resolutions are not achieved, the Company will vigorously defend its positions through litigation, which if undertaken will likely take several years for final resolution. The statute of limitations on these tax years currently remains open until December 31, 2022.
U.S. Tax Years 2014-2016
In 2021, the IRS completed its examination of Eaton US for tax years 2014 through 2016 and has proposed adjustments, including: (i) transfer pricing adjustments similar to those proposed in the 2005-06 Notice, 2007-10 Notice, and in tax years 2011-2013 for products manufactured in the Company’s facilities in Puerto Rico, and the Dominican Republic and sold to affiliated companies located in the U.S.; (ii) transfer pricing adjustments similar to those proposed in tax years 2011-2013 for products manufactured in one of the Company’s facilities in Mexico and sold to affiliated companies located in the U.S.; and (iii) adjustments similar to those proposed in tax years 2011-2013 challenging the appropriate interest rate on intercompany debt and amount of intercompany fees charged for financial guarantees on external debt. On November 29, 2021, the case was formally assigned to administrative appeals, and the Company will attempt to resolve certain of the issues in this administrative forum. However, if acceptable resolutions are not achieved, the Company will vigorously defend its positions through litigation, which if undertaken will likely take several years for final resolution. The statute of limitations on these tax years currently remains open until December 31, 2022.

Note 12. EATON SHAREHOLDERS' EQUITY
There are 750 million Eaton ordinary shares authorized ($0.01 par value per share), 398.8 million and 398.1 million of which were issued and outstanding at December 31, 2021 and 2020, respectively. Eaton's Memorandum and Articles of Association authorized 40 thousand deferred ordinary shares (€1.00 par value per share) and 10 thousand preferred A shares ($1.00 par value per share), all of which were issued and outstanding at December 31, 2021 and 2020, and 10 million serial preferred shares ($0.01 par value per share), none of which is outstanding at December 31, 2021 and 2020. At December 31, 2021, there were 10,447 holders of record of Eaton ordinary shares. Additionally, 14,835 current and former employees were shareholders through participation in the Eaton Savings Plan, the Eaton Personal Investment Plan, or the Eaton Puerto Rico Retirement Savings Plan.
On February 27, 2019, the Board of Directors adopted a share repurchase program for share repurchases up to $5.0 billion of ordinary shares (2019 Program). Under the 2019 Program, the ordinary shares are expected to be repurchased over time, depending on market conditions, the market price of ordinary shares, capital levels, and other considerations. During 2021 and 2020, 0.9 million and 17.1 million ordinary shares, respectively, were repurchased under the 2019 Program in the open market at a total cost of $122 million and $1,608 million, respectively. On February 23, 2022, the Board renewed the 2019 Program by providing authority for up to $5.0 billion in repurchases to be made during the three-year period commencing on that date (2022 Program).
Eaton has deferral plans that permit certain employees and directors to defer a portion of their compensation. A trust contains $4 million and $3 million of ordinary shares and marketable securities at December 31, 2021 and 2020, respectively, to fund a portion of these liabilities. The marketable securities were included in Other assets and the ordinary shares were included in Shareholders' equity at historical cost.
On February 23, 2022, Eaton's Board of Directors declared a quarterly dividend of $0.81 per ordinary share, a 7% increase over the dividend paid in the fourth quarter of 2021. The dividend is payable on March 31, 2022 to shareholders of record on March 11, 2022.
Comprehensive Income (Loss)

Net Income Per Share Attributable to Eaton Ordinary Shareholders
A summary of the calculation of net income per share attributable to Eaton ordinary shareholders is as follows:

(In millions except for per share data) | 2021 |  | 2020 |  | 2019
Net income attributable to Eaton ordinary shareholders | $ | 2,144 |  |  | $ | 1,410 |  |  | $ | 2,211 |
Weighted-average number of ordinary shares outstanding - diluted | 401.6 |  |  | 404.0 |  |  | 420.8 |
Less dilutive effect of equity-based compensation | 2.9 |  |  | 1.8 |  |  | 1.8 |
Weighted-average number of ordinary shares outstanding - basic | 398.7 |  |  | 402.2 |  |  | 419.0 |
Net income per share attributable to Eaton ordinary shareholders |  |  |  |  |
Diluted | $ | 5.34 |  |  | $ | 3.49 |  |  | $ | 5.25 |
Basic | 5.38 |  |  | 3.51 |  |  | 5.28 |

In 2021, all stock options were included in the calculation of diluted net income per share attributable to Eaton ordinary shareholders because they were all dilutive. In 2020 and 2019, 0.6 million and 0.8 million of stock options, respectively, were excluded from the calculation of diluted net income per share attributable to Eaton ordinary shareholders because the exercise price of the options exceeded the average market price of the ordinary shares during the period and their effect, accordingly, would have been antidilutive.
Note 13. EQUITY-BASED COMPENSATION
Eaton recognizes equity-based compensation expense based on the grant date fair value of the award. Awards with service conditions or both service and market conditions are expensed over the period during which an employee is required to provide service in exchange for the award. Awards with both service and performance conditions are expensed over the period an employee is required to provide service based on the number of units for which achievement of the performance objective is probable. The Company estimates forfeitures as part of recording equity-based compensation expense.
Restricted Stock Units and Awards
Restricted stock units (RSUs) and restricted stock awards (RSAs) have been issued to certain employees and directors. The fair value of RSUs and RSAs are determined based on the closing market price of the Company’s ordinary shares at the date of grant. The RSUs entitle the holder to receive one ordinary share for each RSU upon vesting, generally over three years. RSAs are issued and outstanding at the time of grant, but remain subject to forfeiture until vested, generally over ten years. A summary of the RSU and RSA activity for 2021 is as follows:

(Restricted stock units and awards in millions) | Number of restricted stock units and awards |  | Weighted-average fair value per unit and award
Non-vested at January 1 | 1.5 |  |  | $ | 85.09 |
Granted | 0.6 |  |  | 132.69 |
Vested | (0.7) |  |  | 91.20 |
Forfeited | (0.1) |  |  | 105.68 |
Non-vested at December 31 | 1.3 |  |  | $ | 104.86 |

Information related to RSUs and RSAs is as follows:

(In millions) | 2021 |  | 2020 |  | 2019
Pre-tax expense for RSUs and RSAs | $ | 61 |  |  | $ | 58 |  |  | $ | 57 |
After-tax expense for RSUs and RSAs | 48 |  |  | 46 |  |  | 45 |
Fair value of vested RSUs and RSAs | 92 |  |  | 75 |  |  | 103 |

As of December 31, 2021, total compensation expense not yet recognized related to non-vested RSUs and RSAs was $82 million, and the weighted-average period in which the expense is expected to be recognized is 2.7 years. Excess tax benefit for RSUs and RSAs totaled $5 million, $2 million and $3 million for 2021, 2020, and 2019, respectively.

Performance Share Units
Performance share units (PSUs) have been issued to certain employees that vest based on the satisfaction of a three-year service period and total shareholder return relative to that of a group of peers. Awards earned at the end of the three-year vesting period range from 0% to 200% of the targeted number of PSUs granted based on the ranking of total shareholder return of the Company, assuming reinvestment of all dividends, relative to a defined peer group of companies. Equity-based compensation expense for these PSUs is recognized over the period during which an employee is required to provide service in exchange for the award. Upon vesting, dividends that have accumulated during the vesting period are paid on earned awards.
The Company uses a Monte Carlo simulation to estimate the fair value of PSUs with market conditions. The principal assumptions utilized in valuing these PSUs include the expected stock price volatility (based on the most recent 3-year period as of the grant date) and the risk-free interest rate (an estimate based on the yield of United States Treasury zero coupon bonds with a three-year maturity as of the grant date). A summary of the assumptions used in determining fair value of these PSUs is as follows:

|  | 2021 |  | 2020 |  | 2019
Expected volatility |  | 35 | % |  | 21 | % |  | 21 | %
Risk-free interest rate |  | 0.20 | % |  | 1.16 | % |  | 2.42 | %
Weighted-average fair value of PSUs granted |  | $ | 159.74 |  |  | $ | 121.01 |  |  | $ | 92.50 |

A summary of these PSUs that vested is as follows:

Stock Options
Under various plans, stock options have been granted to certain employees and directors to purchase ordinary shares at prices equal to fair market value on the date of grant. Substantially all of these options vest ratably during the three-year period following the date of grant and expire 10 years from the date of grant. Compensation expense is recognized for stock options based on the fair value of the options at the date of grant and amortized on a straight-line basis over the period the employee or director is required to provide service.
The Company uses a Black-Scholes option pricing model to estimate the fair value of stock options. The principal assumptions utilized in valuing stock options include the expected stock price volatility (based on the most recent historical period equal to the expected life of the option); the expected option life (an estimate based on historical experience); the expected dividend yield; and the risk-free interest rate (an estimate based on the yield of United States Treasury zero coupon with a maturity equal to the expected life of the option). A summary of the assumptions used in determining the fair value of stock options is as follows:

| 2021 |  | 2020 |  | 2019
Expected volatility | 28 | % |  | 24 | % |  | 23 | %
Expected option life in years | 6.5 |  | 6.6 |  | 6.6

Note 14. FAIR VALUE MEASUREMENTS
Fair value is measured based on an exit price, representing the amount that would be received to sell an asset or paid to satisfy a liability in an orderly transaction between market participants. Fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a fair value hierarchy is established, which categorizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
A summary of financial instruments recognized at fair value, and the fair value measurements used, is as follows:

(In millions) | Total |  | Quoted prices in active markets for identical assets (Level 1) |  | Other observable inputs (Level 2) |  | Unobservable inputs (Level 3)

Eaton values its financial instruments using an industry standard market approach, in which prices and other relevant information is generated by market transactions involving identical or comparable assets or liabilities.
Other Fair Value Measurements
Long-term debt and the current portion of long-term debt had a carrying value of $8,566 million and fair value of $9,232 million at December 31, 2021 compared to $8,057 million and $9,075 million, respectively, at December 31, 2020. The fair value of Eaton's debt instruments was estimated using prevailing market interest rates on debt with similar creditworthiness, terms and maturities and is considered a Level 2 fair value measurement.
Short-Term Investments
Eaton invests excess cash generated from operations in short-term marketable investments. Investments in marketable equity securities are valued at the closing price of the shares. All other short-term investments are at carrying value, which approximates the fair value due to the short-term maturities of these investments. A summary of short-term investments is as follows:

Note 15. DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES
In the normal course of business, Eaton is exposed to certain risks related to fluctuations in interest rates, currency exchange rates and commodity prices. The Company uses various derivative and non-derivative financial instruments, primarily interest rate swaps, currency forward exchange contracts, currency swaps and, commodity contracts to manage risks from these market fluctuations. The instruments used by Eaton are straightforward, non-leveraged instruments. The counterparties to these instruments are financial institutions with strong credit ratings. Eaton maintains control over the size of positions entered into with any one counterparty and regularly monitors the credit rating of these institutions. Such instruments are not purchased and sold for trading purposes.
Derivative financial instruments are accounted for at fair value and recognized as assets or liabilities in the Consolidated Balance Sheets. Accounting for the gain or loss resulting from the change in the fair value of the derivative financial instrument depends on whether it has been designated, and is effective, as part of a hedging relationship and, if so, as to the nature of the hedging activity. Eaton formally documents all relationships between derivative financial instruments accounted for as designated hedges and the hedged item, as well as its risk-management objective and strategy for undertaking the hedge transaction. This process includes linking derivative financial instruments to a recognized asset or liability, specific firm commitment, forecasted transaction, or net investment in a foreign operation. These financial instruments can be designated as:
•Hedges of the change in the fair value of a recognized fixed-rate asset or liability, or the firm commitment to acquire such an asset or liability (a fair value hedge); for these hedges, the gain or loss from the derivative financial instrument, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in income during the period of change in fair value.
•Hedges of the variable cash flows of a recognized variable-rate asset or liability, or the forecasted acquisition of such an asset or liability (a cash flow hedge); for these hedges, the gain or loss from the derivative financial instrument is recognized in Accumulated other comprehensive income and reclassified to income in the same period when the gain or loss on the hedged item is included in income.
•Hedges of the currency exposure related to a net investment in a foreign operation (a net investment hedge); for these hedges, the gain or loss from the derivative financial instrument is recognized in Accumulated other comprehensive income and reclassified to income in the same period when the gain or loss related to the net investment in the foreign operation is included in income.
The gain or loss from a derivative financial instrument designated as a hedge is classified in the same line of the Consolidated Statements of Income as the offsetting loss or gain on the hedged item. The cash flows resulting from these financial instruments are classified in operating activities on the Consolidated Statements of Cash Flows.
For derivatives that are not designated as a hedge, any gain or loss is immediately recognized in income. The majority of derivatives used in this manner relate to risks resulting from assets or liabilities denominated in a foreign currency and certain commodity contracts that arise in the normal course of business.
Eaton uses certain of its debt denominated in foreign currency to hedge portions of its net investments in foreign operations against foreign currency exposure (net investment hedges). Foreign currency denominated debt designated as non-derivative net investment hedging instruments had a carrying value on an after-tax basis of $2,880 million and $2,020 million at December 31, 2021 and 2020, respectively. See Note 8 for additional information about debt.
Interest Rate Risk
Eaton has entered into fixed-to-floating interest rate swaps to manage interest rate risk of certain long-term debt. These interest rate swaps are accounted for as fair value hedges of certain long-term debt. The maturity of the swap corresponds with the maturity of the debt instrument as noted in the table of long-term debt in Note 8. Eaton also entered into several forward starting floating-to-fixed interest rate swaps to manage interest rate risk on a future anticipated debt issuance.

The currency exchange contracts shown in the table above as derivatives not designated as hedges are primarily contracts entered into to manage currency volatility or exposure on intercompany receivables, payables and loans. While Eaton does not elect hedge accounting treatment for these derivatives, Eaton targets managing 100% of the intercompany balance sheet exposure to minimize the effect of currency volatility related to the movement of goods and services in the normal course of its operations. This activity represents the great majority of these currency exchange contracts. The cash flows resulting from the settlement of these derivatives have been classified in investing activities in the Consolidated Statement of Cash Flows.
As of December 31, 2021, the volume of outstanding commodity contracts that were entered into to hedge forecasted transactions:

Commodity |  | December 31, 2021 |  |  |  | Term

Note 17. BUSINESS SEGMENT AND GEOGRAPHIC REGION INFORMATION
Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated on a regular basis by the chief operating decision maker, or decision making group, in deciding how to allocate resources to an individual segment and in assessing performance. Eaton’s segments are as follows:
Electrical Americas and Electrical Global
The Electrical Americas segment consists of electrical components, industrial components, power distribution and assemblies, residential products, single phase power quality and connectivity, three phase power quality, wiring devices, circuit protection, utility power distribution, power reliability equipment, and services that are primarily produced and sold in North and South America. The Electrical Global segment consists of electrical components, industrial components, power distribution and assemblies, single phase and three phase power quality, and services that are primarily produced and sold outside of North and South America; as well as hazardous duty electrical equipment, emergency lighting, fire detection, intrinsically safe explosion-proof instrumentation, and structural support systems that are produced and sold globally. The principal markets for these segments are industrial, institutional, governmental, utility, commercial, residential and information technology. These products are used wherever there is a demand for electrical power in commercial buildings, data centers, residences, apartment and office buildings, hospitals, factories, utilities, and industrial and energy facilities. The segments share certain common global customers, but a large number of customers are located regionally. Sales are made through distributors, resellers, and manufacturers' representatives, as well as directly to original equipment manufacturers, utilities, and certain other end users.
Hydraulics
On August 2, 2021, Eaton completed the sale of the Hydraulics business to Danfoss A/S. The Hydraulics business sold hydraulics components, systems and services for industrial and mobile equipment. The Hydraulics business offered a wide range of power products including pumps, motors and hydraulic power units; a broad range of controls and sensing products including valves, cylinders and electronic controls; a full range of fluid conveyance products including industrial and hydraulic hose, fittings, and assemblies, thermoplastic hose and tubing, couplings, connectors, and assembly equipment; industrial drum and disc brakes.

eMobility
The eMobility segment designs, manufactures, markets, and supplies mechanical, electrical, and electronic components and systems that improve the power management and performance of both on-road and off-road vehicles. Products include high voltage inverters, converters, fuses, onboard chargers, circuit protection units, vehicle controls, power distribution, fuel tank isolation valves, and commercial vehicle hybrid systems. The principle markets for the eMobility segment are original equipment manufacturers and aftermarket customers of passenger cars, commercial vehicles, and construction, agriculture, and mining equipment.
Other Information
No single customer represented greater than 10% of net sales in 2021, 2020 or 2019, respectively.
The accounting policies of the business segments are generally the same as the policies described in Note 1, except that, as described further in the following paragraph, certain items are not allocated to the businesses. Intersegment sales and transfers are accounted for at the same prices as if the sales and transfers were made to third parties. These intersegment sales are eliminated in consolidation. Operating profit includes the operating profit from intersegment sales.
Corporate includes all the Company's amortization of intangible assets, interest expense-net and restructuring program costs (Note 16) and the non-service cost portion of pensions and other postretirement benefits expense. Other expense-net includes all the Company's costs associated with acquisitions, divestitures, and gains and losses on the sale of certain businesses and other items that are of a corporate or functional governance nature. For purposes of business segment performance measurement, a portion of corporate costs, excluding amortization of intangibles assets, acquisition integration and divestiture costs, and restructuring program charges, are allocated to the businesses. These allocations are periodically adjusted to pass on year-over-year cost savings or increases to the businesses in a manner that is consistent with how the chief operating decision maker assesses performance. Identifiable assets of the business segments exclude goodwill, other intangible assets, and general corporate assets, which principally consist of certain cash, short-term investments, deferred income taxes, certain accounts receivable, certain property, plant and equipment, and certain other assets.

Restructuring
In the second quarter of 2020, Eaton decided to undertake a multi-year restructuring program to reduce its cost structure and gain efficiencies in its business segments and at corporate in order to respond to declining market conditions brought on by the COVID-19 pandemic. Since the inception of the program, the Company has incurred charges of $292 million. These restructuring activities are expected to incur additional expenses of $28 million in 2022 primarily comprised of plant closing and other costs, resulting in total estimated charges of $320 million for the entire program. The projected mature year savings from these restructuring actions are expected to be $230 million when fully implemented in 2023. Additional information related to this restructuring is presented in Note 16.
Summary of Results of Operations
A summary of Eaton’s Net sales, Net income attributable to Eaton ordinary shareholders, and Net income per share attributable to Eaton ordinary shareholders - diluted is as follows:

(In millions except for per share data) | 2021 |  | 2020 |  | 2019
Net sales | $ | 19,628 |  |  | $ | 17,858 |  |  | $ | 21,390 |
Net income attributable to Eaton ordinary shareholders | 2,144 |  |  | 1,410 |  |  | 2,211 |
Net income per share attributable to Eaton ordinary shareholders - diluted | $ | 5.34 |  |  | $ | 3.49 |  |  | $ | 5.25 |

During 2019, the Company’s results of operations were impacted by negative currency translation and weaker than expected growth in the Company’s end markets, particularly in the second half of 2019. Despite the declining market conditions and unfavorable impact of currency translation, the Company generated solid operating margins and Net income per ordinary share.
During 2020, the Company's results of operations were impacted by the COVID-19 pandemic. Organic sales were down 11% in 2020 primarily due to the impact from the COVID-19 pandemic. The divestitures of the Lighting and Automotive Fluid Conveyance businesses reduced sales, which was partially offset by growth from the acquisitions of Souriau-Sunbank Connection Technologies (Souriau-Sunbank) and Power Distribution, Inc.
During 2021, the Company's organic sales increased 10% as end-markets and regions served by our business segments have largely recovered from the negative impact of the COVID-19 pandemic. Our Electrical Global, Vehicle and eMobility business segments all realized organic growth greater than 10% during the year. This level of organic growth was achieved despite supply chain constraints limiting the availability of materials in select businesses, travel restrictions continuing to impact commercial aviation, and reduced production levels at our customers leading to historic low vehicle inventory. Additionally, over the past several years, Eaton has completed a number of transactions to add higher growth, better margin businesses to its portfolio. These portfolio updates, along with continued improvements in supply chains and recovery of the Aerospace and Vehicle markets from the pandemic, have the Company better aligned with secular growth trends and well positioned for expected further growth.
COVID-19
The Company has been impacted by the COVID-19 pandemic in select markets and industries. As a result, our businesses have been focused on cost control measures where appropriate to offset the volume declines we experienced in addition to executing on our multi-year restructuring program we decided to undertake in the second quarter of 2020. In 2021, the Company has seen broad-based strength in its end-markets and regions as our businesses have largely recovered from the negative impact of the COVID-19 pandemic. However as global economies recover, many of our businesses have been impacted by supply chain disruptions, inflation and labor shortages. Additionally, our Aerospace business segment continues to see some softness in demand due to the impact of continued travel restrictions on commercial aviation, particularly in international travel.
Eaton's products and support services are vital to hospitals, emergency services, military sites, utilities, public works, transportation, and shipping providers. In addition, data centers, retail outlets, airports, and governments, as well as the networks that support schools and remote workers, rely on the Company's products to serve their customers and communities. As a result, the Company's plants are generally not subject to extended shutdowns.
The Company continues to monitor the pandemic’s impact throughout the world, including guidance from governmental authorities and world health organizations. The Company’s actions to protect the safety and health of its workforce are aligned with its preventive health protocols and those of governmental authorities and health organizations including the Centers for Disease Controls (U.S.) and the World Health Organization.

RESULTS OF OPERATIONS
Non-GAAP Financial Measures
The following discussion of Consolidated Financial Results includes certain non-GAAP financial measures. These financial measures include adjusted earnings and adjusted earnings per ordinary share, each of which differs from the most directly comparable measure calculated in accordance with generally accepted accounting principles (GAAP). A reconciliation of adjusted earnings and adjusted earnings per ordinary share to the most directly comparable GAAP measure is included in the Consolidated Financial Results table below. During the first quarter of 2021, the Company revised its definition of adjusted earnings to exclude intangible asset amortization expense and prior periods have been retrospectively adjusted to apply this change. Management believes that these financial measures are useful to investors because they exclude certain transactions, allowing investors to more easily compare Eaton’s financial performance period to period. Management uses this information in monitoring and evaluating the on-going performance of Eaton.
Acquisition and Divestiture Charges
Eaton incurs integration charges and transaction costs to acquire and integrate businesses, and transaction, separation and other costs to divest and exit businesses. Eaton also recognizes gains and losses on the sale of businesses. A summary of these Corporate items is as follows:

(In millions except for per share data) | 2021 |  | 2020 |  | 2019
Acquisition integration, divestiture charges and transactions costs | $ | 349 |  |  | $ | 288 |  |  | $ | 198 |
Gain on the sale of the Hydraulics and Lighting businesses | (617) |  |  | (221) |  |  | — |
Total charges (income) before income taxes | (268) |  |  | 67 |  |  | 198 |
Income tax expense (benefit) | 362 |  |  | 66 |  |  | (24) |
Total after income taxes | $ | 94 |  |  | $ | 133 |  |  | $ | 174 |
Per ordinary share - diluted | $ | 0.23 |  |  | $ | 0.33 |  |  | $ | 0.42 |

Acquisition integration, divestiture charges and transaction costs in 2021 are primarily related to the divestiture of the Hydraulics business, the acquisitions of Tripp Lite, Cobham Mission Systems, Souriau-Sunbank Connection Technologies, and Ulusoy Elektrik Imalat Taahhut ve Ticaret A.S., and other charges to acquire and exit businesses including certain indemnity claims associated with the sale of 50% interest in the commercial vehicle automated transmission business in 2017. Charges in 2020 are primarily related to the divestitures of the Hydraulics business and the Lighting business, the acquisitions of Souriau-Sunbank, Ulusoy Elektrik, and Power Distribution, Inc., and other charges to exit businesses. Charges in 2019 related to the divestiture of the Lighting business, the acquisitions of Ulusoy Elektrik, ISG, and Souriau-Sunbank, the loss on the sale of the Automotive Fluid Conveyance business, and other charges to exit businesses. These charges were included in Cost of products sold, Selling and administrative expense, Research and development expense, Interest expense - net, or Other expense - net. In Business Segment Information in Note 17, the charges were included in Other expense - net.
Intangible Asset Amortization Expense
Intangible asset amortization expense is as follows:

(In millions except for per share data) | 2021 |  | 2020 |  | 2019

Net Sales

Changes in Net sales are summarized as follows: |  |  |  |  |  |  |  |  |
| 2021 |  |  |  | 2020 |  |  |  |
Organic growth | 10 | % |  |  |  | (11) | % |  |  |  |
Acquisitions of businesses | 5 | % |  |  |  | 2 | % |  |  |  |
Divestitures of businesses | (6) | % |  |  |  | (7) | % |  |  |  |
Foreign currency | 1 | % |  |  |  | (1) | % |  |  |  |
Total increase (decrease) in Net sales | 10 | % |  |  |  | (17) | % |  |  |  |

Organic sales increased 10% in 2021 due to broad-based strength in end-markets and regions as our business segments have largely recovered from the negative impact of the COVID-19 pandemic. T his organic growth was achieved despite the supply chain constraints experienced by the Electrical Americas business segment, and customers of the Vehicle and eMobility business segments also experienced supply chain constraints leading to reduced production levels. Additionally, organic sales in the Aerospace business segment continued to be impacted by travel restrictions from the COVID-19 pandemic on commercial aviation. The decrease in organic sales in 2020 was primarily due to the impact from the COVID-19 pandemic, with lower sales in all business segments.
The acquisitions of Tripp Lite and Cobham Mission Systems increased sales in 2021, while the divestitures of the Hydraulics and Lighting businesses reduced sales.
Gross Profit
Gross profit margin increased from 30.5% in 2020 to 32.3% in 2021 primarily due to higher sales volumes and savings from restructuring actions. Organic sales volumes improved in the Electrical Americas, Electrical Global, and Vehicle business segments, and declined in the Aerospace business segment. Gross profit also improved due to the net impact of the acquisitions of Tripp Lite and Cobham Mission Systems and the divestiture of the Hydraulics business. Conversely, commodity and logistics inflation had an unfavorable impact on gross margin during 2021. Gross profit margin decreased from 33.0% in 2019 to 30.5% in 2020 primarily due to the impact from the COVID-19 pandemic, with lower sales in all business segments.

Income Taxes
During 2021, income tax expense of $750 million was recognized (an effective tax rate of 25.9%) compared to income tax expense of $331 million in 2020 (an effective tax rate of 19.0%) and income tax expense of $378 million in 2019 (an effective tax rate of 14.6%). The increase in the effective tax rate from 19.0% in 2020 to 25.9% in 2021 was primarily due to the tax expense on the gain from the sale of the Hydraulics business in 2021 discussed in Note 2. The increase in the effective tax rate from 14.6% in 2019 to 19.0% in 2020 was primarily due to the tax expense on the gain from the sale of the Lighting business in 2020 discussed in Note 2, partially offset by a tax benefit on the restructuring charges discussed in Note 16. Additionally, see Note 11 for income tax rate reconciliations from Ireland's national statutory rate to the consolidated effective rate.
Net Income
Net income attributable to Eaton ordinary shareholders of $2,144 million in 2021 increased 52% compared to $1,410 million in 2020. Net income in 2021 and 2020 included after-tax gains of $197 million on the sale of the Hydraulics business and $91 million on the sale of the Lighting business, respectively. Excluding these gains, the increase in 2021 net income was primarily due to higher gross profit and lower restructuring program charges, partially offset by higher income tax expense, acquisition and divestiture charges, and intangible asset amortization expense. Net income attributable to Eaton ordinary shareholders of $1,410 million in 2020 decreased 36% compared to $2,211 million in 2019. Net income in 2020 included an after-tax gain of $91 million on the sale of the Lighting business. The decrease in 2020 net income was primarily due to lower sales volumes as a result of the COVID-19 pandemic.
Net income per ordinary share increased to $5.34 in 2021 compared to $3.49 in 2020. Net income per ordinary share in 2021 and 2020 included $0.49 and $0.22 from the sale of the Hydraulics and Lighting businesses, respectively. Excluding these gains, the increase in Net income per ordinary share in 2021 was due to higher Net income attributable to Eaton ordinary shareholders and the impact of the Company's share repurchases over the past two years. Net income per ordinary share decreased to $3.49 in 2020 compared to $5.25 in 2019. The decrease in Net income per ordinary share in 2020 was due to lower Net income attributable to Eaton ordinary shareholders, adjusted for the impact of the Company's share repurchases over the past few years.
Adjusted Earnings
Adjusted earnings of $2,659 million in 2021 increased 34% compared to Adjusted earnings of $1,985 million in 2020. The increase in Adjusted earnings in 2021 was primarily due to higher Net income attributable to Eaton ordinary shareholders, adjusted for acquisition and divestiture charges, restructuring program charges, and intangible asset amortization expense. Adjusted earnings of $1,985 million in 2020 decreased 26% compared to Adjusted Earnings of $2,668 million in 2019. The decrease in Adjusted earnings in 2020 was primarily due to lower Net income attributable to Eaton ordinary shareholders, adjusted for acquisition and divestiture charges, and restructuring program charges.
Adjusted earnings per ordinary share increased to $6.62 in 2021 compared to $4.91 in 2020. The increase in Adjusted earnings per ordinary share in 2021 was due to higher Adjusted earnings and the impact of the Company's share repurchases over the past two years. Adjusted earnings per ordinary share decreased to $4.91 in 2020 compared to $6.34 in 2019. The decrease in Adjusted earnings per ordinary share in 2020 was due to lower Adjusted earnings, adjusted for the impact of the Company's share repurchases over the past few years.

Total increase (decrease) in Net sales | 8 | % |  |  |  | (18) | % |  |  |  |

The increase in organic sales in 2021 was primarily due to broad-based strength in end-markets as they have largely recovered from the COVID-19 pandemic with particular strength in residential and data centers, partially offset by weakness in sales to utilities. This organic growth was achieved despite the supply chain constraints experienced by the Electrical Americas business segment during 2021, which had a negative impact on Net sales. The decrease in organic sales in 2020 was primarily driven by the impact of the COVID-19 pandemic, partially offset by growth in residential, data center, and utility end-markets.
The operating margin increased from 20.2% in 2020 to 20.6% in 2021 primarily due to higher organic sales volumes, the favorable net impact of an acquisition and a divestiture, and savings from restructuring actions. Conversely, commodity and logistics inflation had an unfavorable impact on the operating margin. The operating margin increased from 18.9% in 2019 to 20.2% in 2020 primarily due to the favorable impact from the divestiture of the Lighting business and cost containment actions to counteract the impact of the COVID-19 pandemic, partially offset by lower volumes.

The increase in organic sales in 2021 was primarily due to broad-based strength in end-markets as they have largely recovered from the COVID-19 pandemic. The decrease in organic sales in 2020 was primarily driven by the impact of the COVID-19 pandemic, with particular weakness in global oil and gas markets and industrial applications.
The operating margin increased from 15.9% in 2020 to 18.7% in 2021 primarily due to higher sales volumes and savings from restructuring actions, partially offset by commodity and logistics inflation. The operating margin decreased from 17.3% in 2019 to 15.9% in 2020 primarily due to lower sales volumes and unfavorable product mix, partially offset by cost containment actions to mitigate the impact of the COVID-19 pandemic.

On August 2, 2021, Eaton completed the sale of the Hydraulics business segment. As a result, net sales and operating profit for 2021 are not directly comparable to 2020, since 2021 only includes the results of the Hydraulics business through the date of the sale.
The decrease in organic sales in 2020 was primarily due to the impact from the COVID-19 pandemic, with weakness at both OEMs and distributors globally.
The operating margin increased from 8.8% in 2019 to 10.1% in 2020 primarily due to depreciation expense no longer being charged as a result of the business being classified as held for sale as discussed in Note 2 and cost containment actions to counteract the impact of the COVID-19 pandemic, partially offset by lower sales volumes.

The decrease in organic sales in 2021 was primarily due to the impact of continued travel restrictions from the COVID-19 pandemic on commercial aviation and weakness in military aftermarket. The decrease in organic sales in 2020 was primarily due to the impact of the COVID-19 pandemic on commercial aviation, partially offset by growth in military sales.
The operating margin increased from 18.6% in 2020 to 21.9% in 2021 primarily due to the acquisition of Cobham Mission Systems and savings from restructuring actions, partially offset by lower organic sales volumes. The operating margin decrease from 24.0% in 2019 to 18.6% in 2020 primarily due to lower sales volumes and the acquisition of Souriau-Sunbank, partially offset by cost containment actions to mitigate the impact of the COVID-19 pandemic.

The increase in organic sales in 2021 was primarily due to strength in all regions compared to 2020 which was significantly impacted by plant shutdowns due to the COVID-19 pandemic. This organic growth was achieved despite the Vehicle business segment's organic sales being negatively impacted in 2021 as a result of its customers experiencing supply chain constraints leading to reduced production levels and historic low vehicle inventory. The decrease in organic sales in 2020 was driven by plant shutdowns in the second quarter of 2020, lower Class 8 OEM production, and weakness in light vehicle sales primarily due to the impact from the COVID-19 pandemic.
The operating margin increased from 11.5% in 2020 to 17.4% in 2021 primarily due to higher sales volumes and savings from restructuring actions, partially offset by commodity and logistics inflation. The operating margin decreased from 15.1% in 2019 to 11.5% in 2020 primarily due to lower sales volumes, partially offset by cost containment actions to mitigate the impact of the COVID-19 pandemic.

The increase in organic sales in 2021 was primarily due to strength in North American and Asia Pacific regions compared to 2020 which was significantly impacted by plant shutdowns due to the COVID-19 pandemic. This organic growth was achieved despite the eMobility business segment's organic sales being negatively impacted in 2021 as a result of its customers experiencing supply chain constraints leading to reduced production levels. The decrease in organic sales in 2020 was primarily due to the impact from the COVID-19 pandemic, with particular weakness in the legacy internal combustion engine platforms.
The operating margin decreased from negative 2.7% in 2020 to negative 8.5% in 2021 primarily due to increased research and development costs and manufacturing start-up costs associated with new electric vehicle programs, and commodity and logistics inflation, partially offset by higher sales volumes. The operating margin decreased from 5.3% in 2019 to negative 2.7% in 2020 primarily due to lower sales volumes and increased research and development costs.

Total corporate expense was $810 million in 2021 compared to Total corporate expense of $1,191 million in 2020. The decrease in Total corporate expense was primarily due to lower Other expense - net, lower Restructuring program charges, and the favorable impact of the freeze on the Company's United States pension plans, partially offset by higher Intangible asset amortization expense due to acquisitions of businesses. The decrease in Other expense - net is primarily due to the 2021 gain on sale of the Hydraulics business exceeding the 2020 gain on the sale of the Lighting business by $396 million. This decrease was partially offset by higher acquisition and divestiture charges and higher other corporate expenses due to the removal of the temporary cost containment actions taken during 2020 to mitigate the impact of the COVID-19 pandemic. Total corporate expense was $1,191 million in 2020 compared to Total Corporate expense of $1,120 million in 2019. The increase in Total corporate expense was primarily due to higher Restructuring program charges, partially offset by lower Other expense - net. The decrease in Other expense - net is primarily due to the 2020 gain on the sale of the Lighting business, partially offset by higher acquisition and divestiture charges.

LIQUIDITY, CAPITAL RESOURCES, AND FINANCIAL CONDITION
Liquidity and Financial Condition
Eaton’s objective is to finance its business through operating cash flow and an appropriate mix of equity and long-term and short-term debt. By diversifying its debt maturity structure, Eaton reduces liquidity risk.
On March 8, 2021, a subsidiary of Eaton issued Euro denominated notes (2021 Euro Notes) with a face value of €1,500 million ($1,798 million), in accordance with Regulation S promulgated under the Securities Act of 1933, as amended. The 2021 Euro Notes are comprised of two tranches of €900 million and €600 million, which mature in 2026 and 2030, respectively, with interest payable annually at a respective rate of 0.128% and 0.577%. The issuer received proceeds totaling €1,494 million ($1,790 million) from the issuance, net of financing costs and discounts.
On May 17, 2021, the Company entered into a $2,500 million 364-day revolving credit facility, which brought the Company’s total revolving credit facilities to $4,500 million. At June 30, 2021, the Company had access to the commercial paper markets through its $4,500 million commercial paper program, of which $3,372 million was outstanding including funds to finance the acquisition of Cobham Mission Systems discussed in Note 2. Eaton used the proceeds from the sale of the Hydraulics business, which was completed August 2, 2021, to reduce its outstanding commercial paper borrowings.
On September 22, 2021, the Company downsized the 364-day revolving credit facility from $2,500 million to $500 million, which reduced the Company's total revolving credit facilities to $2,500 million. In September 2021, the Company also downsized its commercial paper program to $2,500 million.
On October 4, 2021, the Company replaced its existing $500 million 364-day revolving credit facility, $750 million five-year revolving credit facility, $500 million four-year revolving credit facility, and $750 million five-year revolving credit facility, with a new $500 million 364-day revolving credit facility and a new $2,000 million five-year revolving credit facility that will expire on October 4, 2026. The revolving credit facilities totaling $2,500 million are used to support commercial paper borrowings and are fully and unconditionally guaranteed by Eaton and certain of its direct and indirect subsidiaries on an unsubordinated, unsecured basis. There were no borrowings outstanding under Eaton’s revolving credit facilities at December 31, 2021. The Company maintains access to the commercial paper markets through its $2,500 million commercial paper program, of which none was outstanding on December 31, 2021. In addition to the revolving credit facilities, the Company also had available lines of credit of $972 million from various banks primarily for the issuance of letters of credit, of which there was $335 million outstanding at December 31, 2021.
Eaton received proceeds of $1.4 billion from the sale of its Lighting business in 2020 and $3.1 billion from the sale of its Hydraulics business in 2021. The Company paid $4.45 billion to acquire Tripp Lite and Cobham Mission Systems in 2021.
Over the course of a year, cash, short-term investments, and short-term debt may fluctuate in order to manage global liquidity. As of December 31, 2021 and 2020, Eaton had cash of $297 million and $438 million, short-term investments of $271 million and $664 million, and short-term debt of $13 million and $1 million, respectively. Eaton believes it has the operating flexibility, cash flow, cash and short-term investment balances, availability under existing revolving credit facilities, and access to capital markets in excess of the liquidity necessary to meet future operating needs of the business, fund capital expenditures and acquisitions of businesses, as well as scheduled payments of long-term debt.
For additional information on financing transactions and debt, see Note 8.
Eaton’s credit facilities and indentures governing certain long-term debt contain various covenants, the violation of which would limit or preclude the use of the credit facilities for future borrowings, or might accelerate the maturity of the related outstanding borrowings covered by the indentures. At Eaton’s present credit rating level, the most restrictive financial covenant provides that the ratio of secured debt (or lease payments due under a sale and leaseback transaction) to adjusted consolidated net worth (or consolidated net tangible assets, in each case as defined in the relevant credit agreement or indenture) may not exceed 10%. Eaton's actual ratios are substantially below the required threshold. In addition, Eaton is in compliance with each of its debt covenants for all periods presented.

Operating Cash Flow
Net cash provided by operating activities decreased by $781 million in 2021 compared to 2020. The decrease in net cash provided by operating activities in 2021 was primarily due to higher working capital balances to support the Company’s organic growth as our business segments have largely recovered from the negative impact of the COVID-19 pandemic, taxes paid on the sale of the Hydraulics business, and a $200 million pension contribution to Eaton's U.S. qualified pension plan in 2021.
Net cash provided by operating activities decreased by $507 million in 2020 compared to 2019. The decrease in net cash provided by operating activities in 2020 was driven by lower net income, partially offset by lower working capital balances compared to 2019.
Investing Cash Flow
Net cash used in investing activities increased by $2,161 million in 2021 compared to 2020. The increase in the use of cash was primarily driven by cash paid in 2021 for business acquisitions of $4,500 million compared to cash paid in 2020 for business acquisitions of $200 million, partially offset by proceeds received in 2021 from the sale of Hydraulics business of $3,129 million compared to proceeds received in 2020 from the sale of the Lighting business of $1,408 million, and net sales of short-term investments of $379 million in 2021 compared to net purchases of $441 million in 2020. Capital expenditures were $575 million in 2021 compared to $389 million in 2020.
Net cash provided by investing activities increased by $2,263 million in 2020 compared to 2019. The increase in the source of cash was primarily driven by proceeds from the sale of the Lighting business and lower cash paid for business acquisitions, partially offset by net purchases of short-term investments of $441 million in 2020 compared to net purchases of $70 million in 2019. Capital expenditures were $389 million in 2020 compared to $587 million in 2019.
Financing Cash Flow
Net cash used in financing activities decreased by $2,723 million in 2021 compared to 2020. The decrease in the use of cash was primarily due to higher proceeds from borrowings of $1,798 million in 2021 compared to no proceeds from borrowings in 2020, lower share repurchases of $122 million in 2021 compared to $1,608 million in 2020, and net proceeds of short-term debt of $20 million in 2021 compared to net payments of $254 million in 2020, partially offset by higher payments on borrowings of $1,013 million in 2021 compared to $249 million in 2020.
Net cash used in financing activities increased by $1,764 million in 2020 compared to 2019. The increase in the use of cash was primarily due to no proceeds from borrowings in 2020 compared to $1,232 million in 2019 and higher share repurchases of $1,608 million in 2020 compared to $1,029 million in 2019.
Uses of Cash
Purchases of Goods and Services
The Company purchases goods and services in the normal course of business based on expected usage. For certain purchases, the Company enters into purchase obligations with various vendors, which include short-term and long-term commitments for purchases of raw materials, outstanding non-cancelable purchase orders, releases under blanket purchase orders, and commitments under ongoing service arrangements. As of December 31, 2021, the Company has purchase obligations to support the operation of its business similar to those included in historical cash flow trends.
Capital Expenditures
Capital expenditures were $575 million, $389 million, and $587 million in 2021, 2020 and 2019, respectively. Eaton expects approximately $650 million in capital expenditures in 2022.

Dividends
Cash dividend payments were $1,219 million, $1,175 million, and $1,201 million for 2021, 2020 and 2019, respectively. On February 23, 2022, Eaton's Board of Directors declared a quarterly dividend of $0.81 per ordinary share, a 7% increase over the dividend paid in the fourth quarter of 2021. The dividend is payable on March 31, 2022 to shareholders of record on March 11, 2022. Payment of quarterly dividends in the future depends upon the Company’s ability to generate net income and operating cash flows, among other factors, and is subject to declaration by the Eaton Board of Directors. The Company intends to continue to pay quarterly dividends in 2022.
Share Repurchases
On February 27, 2019, the Board of Directors adopted a share repurchase program for share repurchases up to $5.0 billion of ordinary shares (2019 Program). Under the 2019 Program, the ordinary shares are expected to be repurchased over time, depending on market conditions, the market price of ordinary shares, capital levels, and other considerations. During 2021 and 2020, 0.9 million and 17.1 million ordinary shares, respectively, were repurchased under the 2019 Program in the open market at a total cost of $122 million and $1,608 million, respectively. The Company will continue to pursue share repurchases in 2022 depending on market conditions and capital levels. On February 23, 2022, the Board renewed the 2019 Program by providing authority for up to $5.0 billion in repurchases to be made during the three-year period commencing on that date (2022 Program).
Acquisition of Businesses
The Company paid cash of $4,500 million, $200 million, and $1,180 million to acquire businesses in 2021, 2020 and 2019, respectively. The Company will continue to focus on deploying its capital toward businesses that provide opportunities for higher growth and strong returns, and align with secular trends and its power management strategies.
Debt
The Company manages a number of short-term and long-term debt instruments, including commercial paper. For additional information on financing transactions and debt, see Note 8.
Leases
See Note 7 for maturities of lease liabilities.
Unrecognized Income Tax Benefits
At December 31, 2021, the gross unrecognized income tax benefits totaled $1,120 million and interest and penalties were $128 million. Eaton cannot predict with reasonable certainty the timing of cash settlements with the respective taxing authorities. For additional information about income taxes see Note 11.
Defined Benefits Plans
Pension Plans
During 2021, the fair value of plan assets in the Company’s employee pension plans increased $319 million to $5,919 million at December 31, 2021. The increase in plan assets was primarily due to strong returns on plan assets and the Company's contributions to the pension plans. At December 31, 2021, the net unfunded position of $678 million in pension liabilities consisted of $819 million in plans that have no funding requirements and $97 million in plans that require funding, partially offset by $59 million in the U.S. qualified pension plan that is overfunded and $179 million in all other plans that are overfunded.
Funding requirements are a major consideration in making contributions to Eaton’s pension plans. With respect to the Company’s pension plans worldwide, the Company intends to contribute annually not less than the minimum required by applicable law and regulations. In 2021, $343 million was contributed to the pension plans. The Company anticipates making $114 million of contributions to certain pension plans during 2022. The funded status of the Company’s pension plans at the end of 2022, and future contributions, will depend primarily on the actual return on assets during the year and the discount rate used to calculate certain benefits at the end of the year. For additional information about pension plans see Note 9.

Supply Chain Finance Program
The Company negotiates payment terms directly with its suppliers for the purchase of goods and services. In addition, a third-party financial institution offers a voluntary supply chain finance (SCF) program that enables certain of the Company’s suppliers, at the supplier’s sole discretion, to sell receivables due from the Company to the financial institution on terms directly negotiated with the financial institution. If a supplier elects to participate in the SCF program, the supplier decides which invoices are sold to the financial institution and the Company has no economic interest in a supplier’s decision to sell an invoice. The SCF program does not have a significant impact on the Company’s liquidity as payments by the Company to participating suppliers are paid to the financial institution on the invoice due date, regardless of whether an individual invoice is sold by the supplier to the financial institution. The amounts due to the financial institution for suppliers that participate in the SCF program are included in Accounts payable on the Company’s Consolidated Balance Sheets, and the associated payments are included in operating activities on the Consolidated Statements of Cash Flows. At  December 31, 2021 and 2020, Accounts payable included $151 million and $15 million, respectively, payable to suppliers that have elected to participate in the SCF program.
Guaranteed Debt
Issuers, Guarantors and Guarantor Structure
Eaton Corporation has issued senior notes pursuant to indentures dated April 1, 1994 (the 1994 Indenture), November 20, 2012 (the 2012 Indenture) and September 15, 2017 (the 2017 Indenture). The senior notes of Eaton Corporation are registered under the Securities Act of 1933, as amended (the Registered Senior Notes). Eaton Corporation is also the issuer of one outstanding series of privately placed debt securities (the PPNs), and Eaton Capital Unlimited Company, another subsidiary of Eaton, is the issuer of four outstanding series of debt securities sold in offshore transactions under Regulation S promulgated under the Securities Act (the Eurobonds). The PPNs, the Eurobonds and the Registered Senior Notes (together, the Senior Notes) comprise substantially all of Eaton’s long-term indebtedness.
Substantially all of the Senior Notes, together with the credit facilities described above under Financial Condition and Liquidity (the Credit Facilities), are guaranteed by Eaton and 18 of its subsidiaries. Accordingly, they rank equally with each other. However, because these obligations are not secured, they would be effectively subordinated to any existing or future secured indebtedness of Eaton and its subsidiaries. As of December 31, 2021, Eaton has no material, long-term secured debt. The guaranteed Registered Senior Notes are also structurally subordinated to the liabilities of Eaton's subsidiaries that are not guarantors. Except as described below under Future Guarantors, Eaton is not obligated to cause its subsidiaries to guarantee the Registered Senior Notes.
The table set forth in Exhibit 22 filed with the 2020 Form 10-K filed on February 24, 2021, details the primary obligors and guarantors with respect to the guaranteed Registered Senior Notes.
Terms of Guarantees of Registered Securities
Payment of principal and interest on the Registered Senior Notes is guaranteed, on an unsecured, unsubordinated basis by the subsidiaries of Eaton set forth in the table referenced in Exhibit 22. Each guarantee is full and unconditional, and joint and several. Each guarantor's guarantee is an unsecured obligation that ranks equally with all its other unsecured and unsubordinated indebtedness. The obligations of each guarantor under its guarantee of the Registered Senior Notes is subject to a customary savings clause or similar provision designed to prevent such guarantee from constituting a fraudulent conveyance or otherwise legally impermissible or voidable obligation.
Generally, each guarantee of the Registered Senior Notes by a guarantor other than Eaton provides that it will be automatically and unconditionally released and discharged upon:
(a)the consummation of any transaction permitted under the applicable indenture resulting in such guarantor ceasing to be a subsidiary, such as a sale to a third party;
(b)such guarantee (so long as the guarantor is not obligated under any other U.S. debt obligations), becoming prohibited by any applicable law, rule or regulation or by any contractual obligation;
(c)such guarantee resulting in material adverse tax consequences to Eaton or any of its subsidiaries (so long as the applicable guarantor is not obligated under any other U.S. debt obligation); or
(d)such guarantor becoming a controlled foreign corporation within the meaning Section 957(a) of the Internal Revenue Code (a CFC), or an entity the material assets of which is limited to equity interests of a CFC.
Notwithstanding the foregoing, each guarantee by a direct or indirect parent of Eaton Corporation (other than Eaton) provides that it will be released only under the circumstances described in subparagraphs (b) and (c) above.
The guarantee of Eaton does not contain any release provisions.

Table of Contents
Future Guarantors
The 2012 and 2017 Indentures generally provide that, with certain limited exceptions, any subsidiary of Eaton must become a guarantor if it becomes obligated as borrower or guarantor under any series of debt securities or a syndicated credit facility. Further, any entity that becomes a direct or indirect parent entity of Eaton Corporation and holds any material assets, with certain limited exceptions, or owes any material liabilities must become a guarantor.
The 1994 Indenture does not contain provisions with respect to future guarantors.

CRITICAL ACCOUNTING POLICIES
The preparation of financial statements in conformity with generally accepted accounting principles (GAAP) in the United States requires management to make certain estimates and assumptions that may involve the exercise of significant judgment. For any estimate or assumption used, there may be other reasonable estimates or assumptions that could have been used. However, based on facts and circumstances inherent in developing estimates and assumptions, management believes it is unlikely that applying other such estimates and assumptions would have caused materially different amounts to have been reported. Actual results may differ from these estimates.
Revenue Recognition
Sales are recognized when control of promised goods or services are transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services. The majority of the Company’s sales agreements contain performance obligations satisfied at a point in time when control is transferred to the customer. Sales recognized over time are generally accounted for using an input measure to determine progress completed at the end of the period. Sales for service contracts generally are recognized as the services are provided. For agreements with multiple performance obligations, judgment is required to determine whether performance obligations specified in these agreements are distinct and should be accounted for as separate revenue transactions for recognition purposes. In these types of agreements, we generally allocate sales price to each distinct obligation based on the price of each item sold in separate transactions.
Due to the nature of the work required to be performed for obligations recognized over time, Eaton estimates total costs by contract. The estimate of total costs are subject to judgment. Estimated amounts are included in the recognized sales price to the extent it is not probable that a significant reversal of cumulative sales will occur. Additionally, contracts can be modified to account for changes in contract specifications, requirements or sale price. The effect of a contract modification on the sales price or adjustments to the measure of completion under the input method are recognized as adjustments to revenue on a cumulative catch-up basis.
Eaton records reductions to sales for returns, and customer and distributor incentives, primarily comprised of rebates, at the time of the initial sale. Rebates are estimated based on sales terms, historical experience, trend analysis, and projected market conditions in the various markets served. The rebate programs offered vary across businesses due to the numerous markets Eaton serves, but the most common incentives relate to amounts paid or credited to customers for achieving defined volume levels. Returns are estimated at the time of the sale primarily based on historical experience and recorded gross on the Consolidated Balance Sheet. See Note 3 for additional information.
Impairment of Goodwill and Other Long-Lived Assets
Goodwill
Goodwill is evaluated annually for impairment as of July 1 using either a quantitative or qualitative analysis. Goodwill is tested for impairment at the reporting unit level, and is based on the net assets for each reporting unit, including goodwill and intangible assets. The Company’s reporting units are equivalent to the reportable operating segments, except for the Aerospace segment which has two reporting units. Goodwill is assigned to each reporting unit, as this represents the lowest level that constitutes a business and is the level at which management regularly reviews the operating results. The Company performs a quantitative analysis using a discounted cash flow model and other valuation techniques, but may elect to perform a qualitative analysis.
Additionally, goodwill is evaluated for impairment whenever an event occurs or circumstances change that would indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Events or circumstances that may result in an impairment review include changes in macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, other relevant entity-specific events, specific events affecting the reporting unit or sustained decrease in share price.
The annual goodwill impairment test was performed using a qualitative analysis in 2021 and 2020, except for the eMobility reporting unit which used a quantitative analysis. A qualitative analysis is performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales and operating profit margins, discount rates, industry data, and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative analysis performed for each reporting unit. The results of the qualitative analyses did not indicate a need to perform quantitative analysis.
Goodwill impairment testing was also performed using quantitative analyses in 2020 for the Electrical Americas, Electrical Global, Hydraulics and Aerospace reporting units due to a reorganization of the Company’s businesses and in 2020 as a result of the Hydraulics business being classified as held for sale as discussed in Note 2. The Company used the relative fair value method to reallocate goodwill.

Quantitative analyses were performed by estimating the fair value for each reporting unit using a discounted cash flow model. The model includes estimates of future cash flows, future growth rates, terminal value amounts, and the applicable weighted-average cost of capital used to discount those estimated cash flows. The future cash flows were based on the Company's long-term operating plan and a terminal value was used to estimate the reporting unit's cash flows beyond the period covered by the operating plan. The weighted-average cost of capital is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. These analyses require the exercise of judgments, including judgments about appropriate discount rates, perpetual growth rates, revenue growth, and margin assumptions. Sensitivity analyses were performed around certain of these assumptions in order to assess the reasonableness of the assumptions and the resulting estimated fair values.
Based on these analyses performed in 2021 and 2020, the fair value of Eaton's reporting units continue to substantially exceed their respective carrying amounts and thus, no impairment exists.
Indefinite Life Intangible Assets
Indefinite life intangible assets consist of certain trademarks. They are evaluated annually for impairment as of July 1 using either a quantitative or qualitative analysis to determine whether their fair values exceed their respective carrying amounts. Indefinite life intangible asset impairment testing for 2021 and 2020 was performed using a quantitative analysis. Determining the fair value of these assets requires significant judgment and the Company uses a royalty relief methodology similar to that employed when the associated assets were acquired, but using updated estimates of future sales, cash flows and profitability. Sensitivity analyses were performed around certain of these assumptions in order to assess the reasonableness of the assumptions and the resulting estimated fair values.
Additionally, indefinite life intangible assets are evaluated for impairment whenever an event occurs or circumstances change that would indicate that it is more likely than not that the asset is impaired. Events or circumstances that may result in an impairment review include changes in industry and market considerations, cost factors, financial performance, and other relevant entity-specific events that could affect inputs used to determine the respective fair values of the indefinite-lived intangible assets.
For 2021 and 2020, the fair value of indefinite lived intangible assets exceeded the respective carrying value.
For additional information about goodwill and other intangible assets see Note 6.
Acquisitions of Businesses
The acquisition of a business is accounted for using the acquisition method of accounting which requires assets and liabilities to be recognized at their fair values on the acquisition date. The initial fair value of assets acquired and liabilities assumed may be revised based on the final determination of fair value during the measurement period of 12 months from the acquisition date. The Company generally determines the fair value of intangible assets acquired using third-party valuations that are prepared using discounted cash flow models that rely on the Company's estimates. These estimates require judgement of future revenue growth rates, future margins, and the applicable weighted-average cost of capital used to discount those estimated cash flows. Sensitivity analyses were performed around certain of these assumptions in order to assess the reasonableness of the assumptions and the resulting estimated fair values. For additional information about the acquisitions of businesses see Note 2.

Divestitures of Businesses
The Company records assets and liabilities of a business to be sold as held for sale in the Consolidated Balance Sheet when all the required criteria are met. The held for sale assets and liabilities are initially measured at the lesser of their carrying value or fair value less cost to sell, with any resulting loss being immediately recognized. In each subsequent reporting period until the business is sold, the Company continues to estimate the fair value less cost to sell of the business and recognizes any additional losses, or any gains to the extent losses were previously recorded on the held for sale assets and liabilities.
In the first quarter of 2020, the Company used the relative fair value method to allocate goodwill to the Hydraulics business. The fair value of the Hydraulics business was estimated based on a combination of the price paid to Eaton by Danfoss A/S and a discounted cash flow model. The model includes estimates of future cash flows, future growth rates, terminal value amounts, and the applicable weighted-average cost of capital used to discount those estimated cash flows. The weighted-average cost of capital is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. These analyses require the exercise of judgments, including judgments about appropriate discount rates, perpetual growth rates, revenue growth, and margin assumptions. For additional information about the divestitures of businesses see Note 2.
Recoverability of Deferred Income Tax Assets
Eaton is subject to the income tax laws in the jurisdictions in which it operates. In order to determine the income tax provision for financial statement purposes, Eaton must make significant estimates and judgments about its business operations in these jurisdictions. These estimates and judgments are also used in determining the deferred income tax assets and liabilities that have been recognized for differences between the financial statement and income tax basis of assets and liabilities, and income tax loss carryforwards and income tax credit carryforwards.
Management evaluates the realizability of deferred income tax assets for each jurisdiction in which it operates. If the Company experiences cumulative pre-tax income in a particular jurisdiction in a three-year period including the current and prior two years, management normally concludes that the deferred income tax assets will more likely than not be realizable and no valuation allowance is recognized, unless known or planned operating developments, or changes in tax laws, would lead management to conclude otherwise. However, if the Company experiences cumulative pre-tax losses in a particular jurisdiction in a three-year period including the current and prior two years, management then considers a series of factors in the determination of whether the deferred income tax assets can be realized. These factors include historical operating results, known or planned operating developments, the period of time over which certain temporary differences will reverse, consideration of the utilization of certain deferred income tax liabilities, tax law carryback capability in a particular country, prudent and feasible tax planning strategies, changes in tax laws, and estimates of future earnings and taxable income using the same assumptions as those used for the Company’s goodwill and other impairment testing. After evaluation of these factors, if the deferred income tax assets are expected to be realized within the tax carryforward period allowed for that specific country, management would conclude that no valuation allowance would be required. To the extent that the deferred income tax assets exceed the amount that is expected to be realized within the tax carryforward period for a particular jurisdiction, management would establish a valuation allowance. For additional information about income taxes see Note 11.
Unrecognized Income Tax Benefits
Eaton recognizes an income tax benefit from an uncertain tax position only if it is more likely than not that the benefit would be sustained upon examination by taxing authorities, based on the technical merits of the position. The Company evaluates and adjusts the amount of unrecognized income tax benefits based on changes in law, facts and circumstances. Eaton also estimates, where reasonably possible, the increase or decrease in the amount of unrecognized income tax benefits in the next 12 months.
The evaluation and determination of the amount of unrecognized income tax benefits related to uncertain tax positions is complex and involves both the exercise of judgement and the utilization of certain estimates and assumptions. Each tax position carries unique facts and circumstances that must be evaluated in light of current tax laws, regulations, and judicial decisions. Additionally, the ultimate resolution of the majority of Eaton’s unrecognized income tax benefits is dependent upon uncontrollable factors such as the timing of finalizing resolutions of audit disputes through reaching settlement agreements or concluding litigation, or changes in law.
Pension and Other Postretirement Benefits Plans
The measurement of liabilities related to pension plans and other postretirement benefits plans is based on assumptions related to future events including interest rates, return on plan assets, rate of compensation increases, and health care cost trend rates. Actual plan asset performance will either reduce or increase losses included in accumulated other comprehensive loss, which ultimately affects net income.

The discount rate for United States plans was determined by discounting the expected future benefit payments using a theoretical zero-coupon spot yield curve derived from a universe of high-quality bonds as of the measurement date and solving for the single rate that would generate the same benefit obligation. Only corporate bonds with a rating of Aa, determined by averaging the ratings by Moody’s, Standard & Poor's, and Fitch, were included. Callable bonds that are not make-whole bonds and certain other non-comparable bonds were eliminated. Finally, a subset of bonds was selected by grouping the universe of bonds by duration and retaining 50% of the bonds that had the highest yields.
The discount rates for non-United States plans were determined by region and are based on high quality long-term corporate and government bonds. Consideration has been given to the duration of the liabilities in each plan when selecting the bonds to be used in determining the discount rate.
To estimate the service and interest cost components of net periodic benefit cost for the vast majority of its defined benefits pension and other postretirement benefits plans, the Company used a spot rate approach by applying the specific spot rates along the yield curve used to measure the benefit obligation at the beginning of the period to the relevant projected cash flows.
Key assumptions used to calculate pension and other postretirement benefits expense are adjusted at each year-end. A 1-percentage point change in the assumed rate of return on pension plan assets is estimated to have approximately a $54 million effect on pension expense. Likewise, a 1-percentage point change in the discount rate is estimated to have approximately a $48 million effect on pension expense. A 1-percentage point change in the assumed rate of return on other postretirement benefits assets is estimated to have less than $1 million effect on other postretirement benefits expense. A 1-percentage point change in the discount rate is estimated to have less than $1 million effect on expense for other postretirement benefits plans.
Additional information related to changes in key assumptions used to recognize expense for other postretirement benefits plans is found in Note 9.
MARKET RISK DISCLOSURE
On a regular basis, Eaton monitors third-party depository institutions that hold its cash and short-term investments, primarily for safety of principal and secondarily for maximizing yield on those funds. The Company diversifies its cash and short-term investments among counterparties to minimize exposure to any one of these entities. Eaton also monitors the creditworthiness of its customers and suppliers to mitigate any adverse impact.
Eaton uses derivative instruments to manage exposure to volatility in raw material costs, currency, and interest rates on certain debt instruments. Derivative financial instruments used by the Company are straightforward and non-leveraged. The counterparties to these instruments are financial institutions with strong credit ratings. Eaton maintains control over the size of positions entered into with any one counterparty and regularly monitors the credit rating of these institutions. See Note 15 for additional information about hedges and derivative financial instruments.
Eaton’s ability to access the commercial paper market, and the related cost of these borrowings, is based on the strength of its credit rating and overall market conditions. During 2021, the Company has not experienced any material limitations in its ability to access these sources of liquidity. At December 31, 2021, Eaton had $2,500 million of long-term revolving credit facilities with banks in support of its commercial paper program. It has no borrowings outstanding under these revolving credit facilities.
Interest rate risk can be measured by calculating the short-term earnings impact that would result from adverse changes in interest rates. This exposure results from short-term debt, which includes commercial paper at a floating interest rate, long-term debt that has been swapped to floating rates, and money market investments that have not been swapped to fixed rates. Based upon the balances of investments and floating rate debt at year end 2021, a 100 basis point increase in short-term interest rates would have increased the Company’s net, pre-tax interest expense by $15 million.
Eaton also measures interest rate risk by estimating the net amount by which the fair value of the Company’s financial liabilities would change as a result of movements in interest rates. Based on Eaton’s best estimate for a hypothetical, 100 basis point increase in interest rates at December 31, 2021, the market value of the Company’s debt and interest rate swap portfolio, in aggregate, would decrease by $503 million.

In July 2017, the United Kingdom’s Financial Cond uct Authority, which regulates the London Interbank Offered Rate (LIBOR), announced it intends to phase out LIBOR. The final publication of rates for certain USD LIBOR tenors is expected to be on June 30, 2023. Various parties, including government agencies, are seeking to identify alternative rates to replace LIBOR. The Company has established a cross-functional project team to evaluate the potential impacts of alternative rates as replacements to LIBOR in the Company’s contracts, which primarily include revolving credit facilities, fixed-to-floating interest rate swaps, and forward starting floating-to-fixed interest rate swaps. As of December 31, 2021, the Company’s $500 million 364-day revolving credit facility that will expire on October 3, 2022 and $2,000 million five-year revolving credit facility that will expire on October 4, 2026 both include a transition process from LIBOR to an alternative rate. The Company’s interest rate swaps are expected to settle prior to June 30, 2023. The Company continues to evaluate the potential impacts of the transition from LIBOR to alternative rates in its contracts and the transition is not expected to have a material impact on the consolidated financial statements.
The Company is exposed to fluctuations in commodity prices due to volatility in raw material costs and contractual agreements with suppliers. To partially mitigate this exposure, Eaton enters into commodity contracts for certain raw material purchases with the objective of minimizing changes in inventory cost due to market price fluctuations. These commodity contracts are designated for hedge accounting and are generally less than one year in duration. Based on Eaton’s best estimate for a hypothetical 10% fluctuation in commodity prices the gain or loss would be $4 million. The sensitivity analysis of the effects of changes in commodity prices assumes the notional value to remain constant for the next 12 months. Any change in the value of the contracts would be offset by an inverse change in the value of the underlying hedged transactions.
The Company is exposed to currency risk associated with translating its functional currency financial statements into its reporting currency, which is the U.S. dollar. As a result, the Company is exposed to movements in the exchange rates of various currencies against the U.S. dollar. Eaton also monitors exposure to transactions denominated in currencies other than the functional currency of each country in which the Company operates, and regularly enters into forward contracts to mitigate that exposure. In the aggregate, Eaton’s portfolio of forward contracts related to such transactions was not material to its Consolidated Financial Statements.
