ITEM 1. | BUSINESS

Overview
EnerSys (the “Company,” “we,” or “us”) is a world leader in stored energy solutions for industrial applications. We also manufacture and distribute energy systems solutions and motive power batteries, specialty batteries, battery chargers, power equipment, battery accessories and outdoor equipment enclosure solutions to customers worldwide. Energy Systems which combine enclosures, power conversion, power distribution and energy storage are used in the telecommunication and broadband, utility industries, uninterruptible power supplies, and numerous applications requiring stored energy solutions. Motive Power batteries and chargers are utilized in electric forklift trucks and other industrial electric powered vehicles. Specialty batteries are used in aerospace and defense applications, large over the road trucks, premium automotive and medical. We also provide aftermarket and customer support services to over 10,000 customers in more than 100 countries through a network of distributors, independent representatives and our internal sales force around the world.
During the first quarter of fiscal 2021, the Company's chief operating decision maker, or CODM (the Company's Chief Executive Officer), changed the manner in which he reviews financial information for purposes of assessing business performance and allocating resources, by focusing on the lines of business on a global basis, rather than on geographic basis. As a result of this change, the Company re-evaluated the identification of its operating segments and reportable segments. The new operating segments were identified as Energy Systems, Motive Power and Specialty. The Company’s operating segments also represent its reportable segments under ASC 280, Segment Reporting. Therefore, the Company has changed its segment presentation from three reportable segments based on geographic basis to three reportable segments based on line of business. All prior comparative periods presented have been recast to reflect these changes.
The Company's three reportable segments, based on lines of business, are as follows:
•Energy Systems - uninterruptible power systems, or “UPS” applications for computer and computer-controlled systems, as well as telecommunications systems, switchgear and electrical control systems used in industrial facilities and electric utilities, large-scale energy storage and energy pipelines. Energy Systems also includes highly integrated power solutions and services to broadband, telecom, renewable and industrial customers, as well as thermally managed cabinets and enclosures for electronic equipment and batteries.
•Motive Power - power for electric industrial forklifts used in manufacturing, warehousing and other material handling applications as well as mining equipment, diesel locomotive starting and other rail equipment; and
•Specialty - premium starting, lighting and ignition applications in transportation, energy solutions for satellites, military aircraft, submarines, ships and other tactical vehicles as well as medical and security systems.
See Note 23 to the Consolidated Financial Statements for information on segment reporting.
Fiscal Year Reporting
In this Annual Report on Form 10-K, when we refer to our fiscal years, we state “fiscal” and the year, as in “fiscal 2021”, which refers to our fiscal year ended March 31, 2021. The Company reports interim financial information for 13-week periods, except for the first quarter, which always begins on April 1, and the fourth quarter, which always ends on March 31. The four quarters in fiscal 2021 ended on July 5, 2020, October 4, 2020, January 3, 2021, and March 31, 2021, respectively. The four quarters in fiscal 2020 ended on June 30, 2019, September 29, 2019, December 29, 2019, and March 31, 2020, respectively.
History
EnerSys and its predecessor companies have been manufacturers of industrial batteries for over 125 years. Morgan Stanley Capital Partners teamed with the management of Yuasa, Inc. in late 2000 to acquire from Yuasa Corporation (Japan) its reserve power and motive power battery businesses in North and South America. We were incorporated in October 2000 for the purpose of completing the Yuasa, Inc. acquisition. On January 1, 2001, we changed our name from Yuasa, Inc. to EnerSys to reflect our focus on the energy systems nature of our businesses.
In 2004, EnerSys completed its initial public offering (the “IPO”) and the Company’s common stock commenced trading on the New York Stock Exchange, under the trading symbol “ENS”.

Key Developments
There have been several key stages in the development of our business, which explain to a significant degree our results of operations over the past several years.
In March 2002, we acquired the reserve power and motive power business of the Energy Storage Group of Invensys plc. (“ESGI”). Our successful integration of ESGI provided global scale in both the reserve and motive power markets. The ESGI acquisition also provided us with a further opportunity to reduce costs and improve operating efficiency.
During fiscal years 2003 through 2021, we made thirty-four acquisitions around the globe. There were no acquisitions in fiscal 2021 but in fiscal 2020, we completed the acquisition of NorthStar, headquartered in Stockholm, Sweden and in fiscal 2019, we completed the acquisition of Alpha.
NorthStar Acquisition
On September 30, 2019, we completed the acquisition of NorthStar, for $77.8 million in cash consideration and the assumption of $107.0 million in debt, which was funded using existing cash and credit facilities. NorthStar, through its direct and indirect subsidiaries, manufactures and distributes thin plate pure lead (TPPL) batteries and battery enclosures. NorthStar has two large manufacturing facilities in Springfield, Missouri.
The results of the NorthStar acquisition have been included in our results of operations from the date of acquisition. Pro forma earnings and earnings per share computations have not been presented as this acquisition was not considered material.
The results of operations of NorthStar have been included in our Energy Systems segment and Specialty segment, respectively.
Alpha Acquisition
On December 7, 2018, the Company completed the acquisition of all of the issued and outstanding common stock of Alpha Technologies Services, Inc. (“ATS”) and Alpha Technologies Ltd. (“ATL”), resulting in ATS and ATL becoming wholly-owned subsidiaries of the Company (the “Alpha share purchase”). Additionally, the Company acquired substantially all of the assets of Alpha Technologies Inc. and certain assets of Altair Advanced Industries, Inc. and other affiliates of ATS and ATL (all such sellers, together with ATS and ATL, “Alpha”), in each case in accordance with the terms and conditions of certain restructuring agreements (collectively, the “Alpha asset acquisition” and together with the Alpha share purchase, the “Alpha acquisition”). Based in Bellingham, Washington, Alpha is a global industry leader in the comprehensive commercial-grade energy solutions for broadband, telecom, renewable, industrial and traffic customers around the world. The initial purchase consideration for the Alpha acquisition was $750.0 million of which $650.0 million was paid in cash and the balance was settled by issuing 1,177,630 shares of EnerSys common stock. These shares were issued out of the Company's treasury stock and were valued at $84.92 per share, which was based on the thirty-day volume weighted average stock price of the Company’s common stock at closing, in accordance with the purchase agreement. The 1,177,630 shares had a closing date fair value of $93.3 million, based upon the December 7, 2018 closing date spot rate of $79.20. The total purchase consideration, consisting of cash paid of $650.0 million, shares valued at $93.3 million and adjustment for working capital (due from seller of $0.8 million) was $742.5 million.
The Company funded the cash portion of the acquisition with borrowings from the Amended Credit Facility (as defined in the Liquidity and Capital Resources section in Item 7. below).
The results of operations of Alpha have been included in the Company’s Energy Systems segment beginning December 8, 2018.
Our Customers
We serve over 10,000 customers in over 100 countries, on a direct basis or through our distributors. We are not overly dependent on any particular end market. Our customer base is highly diverse, and no single customer accounts for more than 10% of our revenues.
Our Energy Systems customers consist of both global and regional customers. These customers are in diverse markets including telecom, UPS, electric utilities, security systems, emergency lighting, services to broadband, telecom, renewable and industrial customers, as well as thermally managed cabinets and enclosures for electronic equipment and batteries.

Table of Contents
Our Motive Power products are sold to a large, diversified customer base. These customers include material handling equipment dealers, forklift and heavy truck original equipment manufacturers (“OEMs”) and end users of such equipment. End users include manufacturers, distributors, warehouse operators, retailers, airports, mine operators and railroads.
Our Specialty products are utilized in transportation, aerospace and defense markets. The products are sold globally to OEMs, distribution partners, vehicle fleets and directly to government entities such as the United States of America, Germany and the United Kingdom.
Distribution and Services
We distribute, sell and service our products throughout the world, principally through company-owned sales and service facilities, as well as through independent manufacturers’ representatives. Our company-owned network allows us to offer high-quality service, including preventative maintenance programs and customer support. Our warehouses and service locations enable us to respond quickly to customers in the markets we serve. We believe that the extensive industry experience of our sales organization results in strong long-term customer relationships.
Manufacturing and Raw Materials
We manufacture and assemble our products at manufacturing facilities located in the Americas, EMEA and Asia. With a view toward projected demand, we strive to optimize and balance capacity at our battery manufacturing facilities globally, while simultaneously minimizing our product cost. By taking a global view of our manufacturing requirements and capacity, we believe we are better able to anticipate potential capacity bottlenecks and equipment and capital funding needs.
The primary raw materials used to manufacture our products include lead, plastics, steel and copper. We purchase lead from a number of leading suppliers throughout the world. Because lead is traded on the world’s commodity markets and its price fluctuates daily, we periodically enter into hedging arrangements for a portion of our projected requirements to reduce the volatility of our costs.
Competition
The industrial energy storage market is highly competitive both among competitors who manufacture and sell industrial batteries and other energy storage systems and solutions and among customers who purchase industrial energy solutions. Our competitors range from development stage companies to large domestic and international corporations. Certain of our competitors produce energy storage products utilizing technologies or chemistries different from our own. We compete primarily on the basis of reputation, product quality, reliability of service, delivery and price. We believe that our products and services are competitively priced.
Energy Systems
We compete principally with East Penn Manufacturing, Exide Technologies (Stryten), New Power, C&D Technologies Inc., Vertiv, ABB, Amphenol (Delta/Eltek), as well as Chinese producers.
Motive Power
Our primary global competitors in traditional lead-acid include East Penn Manufacturing, Exide Technologies (Stryten), Hoppecke, Eternity, Midac, Sunlight and TAB, as well as a number of domestic Chinese manufacturers.
Additionally, while lithium-ion battery technology in the motive power space has traditionally been relegated to smaller material handling applications, we have seen the entrance of a number of companies into larger battery types, acting as lithium cell packagers or integrators of cells sourced primarily from Asia. The integrators include forklift original equipment manufacturers either directly or through partnership with other entities.

Table of Contents
Specialty
We compete globally within the Transportation, Aerospace and Defense markets and specialized lithium technologies used in these critical applications. Our TPPL technology is a significant player in the applications using absorbed glass materials (AGM). Our major competitors in AGM technology are Clarios, East Penn Manufacturing, Exide Technologies (Stryten) Stryten, Fiamm, Banner and Atlas. In the Aerospace and Defense specialized markets our main competitors are Eagle Picher and SAFT.
Warranties
Warranties for our products vary geographically and by product type and are competitive with other suppliers of these types of products. Generally, our Energy Systems product warranties range from one to twenty years, our Motive Power product warranties range from one to seven years and from one to four years for Specialty transportation batteries. The length of our warranties is varied to reflect regional characteristics and competitive influences. In some cases, our warranty period may include a pro rata period, which is typically based around the design life of the product and the application served. Our warranties generally cover defects in workmanship and materials and are limited to specific usage parameters.
Intellectual Property
We have numerous patents and patent licenses in the United States and other jurisdictions but do not consider any one patent to be material to our business. From time to time, we apply for patents on new inventions and designs, but we believe that the growth of our business will depend primarily upon the quality of our products and our relationships with our customers, rather than the extent of our patent protection.
We believe we are the leader in TPPL. We believe that a significant capital investment would be required by any party desiring to produce products using TPPL technology for our markets.
We own or possess exclusive and non-exclusive licenses and other rights to use a number of trademarks in various jurisdictions. We have obtained registrations for many of these trademarks in the United States and other jurisdictions. Our various trademark registrations currently have durations of approximately 10 to 20 years, varying by mark and jurisdiction of registration and may be renewable. We endeavor to keep all of our material registrations current. We believe that many such rights and licenses are important to our business by helping to develop strong brand-name recognition in the marketplace.
Seasonality
Our business generally does not experience significant quarterly fluctuations in net sales as a result of weather or other trends that can be directly linked to seasonality patterns, although transportation and power electronics can experience seasonality in colder months. Despite that, historically our fourth quarter is our best quarter with higher revenues and generally more working days while our second quarter is the weakest due to the summer holiday season in Western Europe and North America.
Product and Process Development
Our product and process development efforts are focused on the creation of new stored energy products, and integrated power systems and controls. We allocate our resources to the following key areas:
•the design and development of new products;
•optimizing and expanding our existing product offering;
•waste and scrap reduction;
•production efficiency and utilization;
•capacity expansion without additional facilities; and
•quality attribute maximization.

Environmental Matters and Climate Change Impacts
We are committed to the protection of the environment and train our employees to perform their duties accordingly. In the manufacture of our products throughout the world, we process, store, dispose of and otherwise use large amounts of hazardous materials, especially lead and acid. As a result, we are subject to extensive and evolving environmental, health and safety laws and regulations governing, among other things: the generation, handling, storage, use, transportation and disposal of hazardous materials; emissions or discharges of hazardous materials into the ground, air or water; and the health and safety of our employees. In addition, we are required to comply with the regulation issued from the European Union called Registration, Evaluation, Authorization and Restriction of Chemicals or “REACH”. Under the regulation, companies which manufacture or import more than one ton of a covered chemical substance per year are required to register it in a central database administered by the European Chemicals Agency. The registration process requires the submission of information to demonstrate the safety of chemicals as used and could result in significant costs or delay the manufacture or sale of our products in the European Union. Additionally, industry associations and their member companies, including EnerSys, have scheduled meetings with the European Union member countries to advocate for their support of an exemption for lead compounds. Compliance with these laws and regulations results in ongoing costs. Failure to comply with these laws and regulations, or to obtain or comply with required environmental permits, could result in fines, criminal charges or other sanctions by regulators. From time to time, we have had instances of alleged or actual noncompliance that have resulted in the imposition of fines, penalties and required corrective actions. Our ongoing compliance with environmental, health and safety laws, regulations and permits could require us to incur significant expenses, limit our ability to modify or expand our facilities or continue production and require us to install additional pollution control equipment and make other capital improvements. In addition, private parties, including current or former employees, can bring personal injury or other claims against us due to the presence of, or their exposure to, hazardous substances used, stored, transported or disposed of by us or contained in our products.
Environmental and safety certifications
Sixteen of our facilities in the Americas, EMEA and Asia are certified to ISO 14001 standards. ISO 14001 is a globally recognized, voluntary program that focuses on the implementation, maintenance and continual improvement of an environmental management system and the improvement of environmental performance. Eight facilities in EMEA and Asia are certified to ISO 45001 standards. The ISO 45001 is a globally recognized occupational health and safety management systems standard.
Climate change impacts
The potential impact of climate change on our operations is uncertain. Climate change may result in, among other things, changes in rainfall and storm patterns and intensity and increased temperature and sea levels. As discussed elsewhere in this Annual Report on Form 10-K (Annual Report), including in Item 1A. Risk Factors, our operating results are significantly influenced by weather, and significant changes in historical weather patterns could significantly impact our future operating results. For example, if climate change results in drier weather and more accommodating temperatures over a greater period of time, we may be able to increase our productivity, which could positively impact our revenues and gross margins. Conversely, if climate change results in a greater amount of rainfall, snow, ice or other less accommodating weather conditions, we could experience reduced productivity, which could negatively impact our revenues and gross margins. Further, while an increase in severe weather events, such as hurricanes, tropical storms, blizzards and ice storms, can create a greater amount of emergency restoration service work, it often also can result in delays or other negative consequences for our manufacturing operations, which could negatively impact our financial results. Climate change may also affect the conditions in which we operate, and in some cases, expose us to potentially increased liabilities associated with those environmental conditions. Concerns about climate change could also result in potential new regulations, regulatory actions or requirements to fund energy efficiency activities, any of which could result in increased costs associated with our operations.
We strive to operate our facilities in a manner that protects the environment and the health and safety of our employees, customers and communities. We have implemented company-wide environmental, health and safety policies and practices, which includes monitoring, training and communication of these policies, formulation of relevant policies and standards.

Quality Systems
We utilize a global strategy for quality management systems, policies and procedures, the basis of which is the ISO 9001:2015 standard, a worldwide recognized quality standard. We believe in the principles of this standard and reinforce the same by requiring mandatory compliance for all manufacturing, sales and service locations globally that are registered to the ISO 9001 standard. We also focus on specific plant certifications such as AS9100 (Aerospace), ISO13485:2016 (Medical Devices), ISO/TS 22163:2017 (Rail), TL9000 (Telecom), IATF16949:2018 (Automotive). We have also acquired our first Lithium-Ion product certification in accordance with ISO 26262 (Product Safety).
This strategy enables us to provide consistent quality products and services to meet our customers’ needs.
Human Capital Management
EnerSys is committed to developing a comprehensive, cohesive and positive employee experience. We consider talent acquisition, development, engagement and retention a key driver of our business success.
Our Board of Directors, through the Compensation Committee and the Nominating and Corporate Governance Committee, retains oversight of our human capital management process, including demographics, talent development, employee retention, material aspects of employee compensation, as well as diversity and inclusion, recruitment, and compensation efforts. The Nominating and Corporate Governance Committee reports on human capital matters at each regularly scheduled Board of Directors meeting. The most significant human capital measures, objectives and initiatives include the following:
Equity, Inclusion and Belonging: We strive to create a work environment that emphasizes respect, fairness and dignity and that does not tolerate discrimination or harassment. Individuals are evaluated based on merit, without discrimination, including discrimination based on race, color, religion, national origin, citizenship, marital status, gender (including pregnancy), gender identity, gender expression, sexual orientation, age, disability, veteran status, or other characteristics protected by law. We are committed to providing equal opportunities to every member of our workforce. In addition to following all applicable local laws and regulations, for fiscal year 2022, we have also formed an executive steering committee and funded additional staffing to further support these efforts.
Health, Safety, and Wellness: Our fundamental responsibility as an employer is to provide a safe and healthy workplace for all of our employees. This undertaking is explained further in our Safety and Health Policy. We equally realize that we must address environmental challenges, which include undertaking initiatives to promote greater environmental responsibility and encouraging the development of new technologies.
Our health and safety programs are designed around global standards with appropriate variations addressing the multiple jurisdictions and regulations, specific hazards and unique working environments of our manufacturing and production facilities, service centers and headquarter operations. Above all else, we are dedicated to the safety and well-being of our employees. As the COVID-19 pandemic unfolded in 2020, we quickly shifted to a remote work environment where possible, and provided employees with the resources necessary to effectively perform their job responsibilities. Additionally, we implemented changes to our manufacturing and distribution operations to include the use of personal protective equipment, intensive cleaning measures, and social distancing.
Philanthropy and Volunteerism: EnerSys is strongly committed to being an outstanding corporate citizen on a global basis in all of the countries and communities where we do business. This commitment is reflected in a strong ethic for charitable contributions, endorsement of community activities, encouraging employees to give freely of their own time to serve on boards or committees in many organizations and supporting educational programs in schools and colleges.
We created several committees to assist the company in its philanthropic endeavors that support all communities in which we work. Additionally, we regularly sponsor volunteer events and fundraising campaigns, to encourage our employees to give back to our communities, a commitment that we further support by offering employees paid time off for charitable volunteering.
Training and Career Management: Employees receive regular development feedback through quarterly 1:1 reviews with their manager, which encourages open dialogues to identify and cultivate skills and opportunities. We encourage our leaders to facilitate effective conversations and measure the effectiveness of these conversations by regularly surveying our employees. In addition to training and development opportunities, all new employees are required to participate in substantial training seminars to introduce them to the EnerSys business, our strategy, our culture and philosophies. We encourage all of our employees to engage in ongoing training, professional development and educational advancement programs. Through our
12

Table of Contents
established EnerSys Academy, we provide employees worldwide with resources to expand their knowledge on a broad scope of relevant topics to promote their growth and development.
Compensation and Benefits: To attract, retain and recognize talent, we aim to ensure merit-based, compensation practices and strive to provide competitive compensation and benefit packages to our workforce. We provide employee wages that are consistent with employee positions, skill levels, experience, knowledge and geographic location. We align our executives' and eligible employees' annual bonus opportunity and long-term equity compensation with our stockholders' interests by linking realizable pay with company financial and stock performance. We completed an initial pay equity study in fiscal year 2021 to further evaluate our global pay practices across the organization. In response to the COVID-19 pandemic, we provided resources for well-being and work life flexibility for our employees to take care of themselves and their families.
Environmental, Social and Governance
We have been integrating the fundamental sustainable values of environmental, social, and governance (“ESG”) into our everyday operations and future business strategies. Our sustainability team leads our significant efforts with respect to climate change management, product sustainability, operations, supply chain management, workforce health and safety, diversity, equity, inclusion, and community engagement.
We further believe that the power systems and energy management sector has a key role to play in finding innovative solutions to address global climate change. Our climate change policy underscores our goal to carry out all business activities in a sustainable manner. Our environmental policies and practices aim to protect, conserve, and sustain the world’s natural resources, as well as to protect our customers and the communities in which we live and operate. We also offer a complete battery recycling program to assist our customers in preserving our environment and comply with recycling and waste disposal regulations.
Relationships between EnerSys and our suppliers must be based on mutual respect and integrity. Our purchasing and quality teams strive to maintain the highest standards and principles of business ethics, courtesy and competence in dealings and transactions with suppliers. Our code of supplier conduct reflects our commitment to the values of honesty, integrity, respect, and responsibility. We expect our suppliers will share and embrace our values, as well as our commitment to regulatory compliance.
We have formed an ESG steering committee, which includes members of senior management and funded additional staffing to further support the ongoing development of our ESG program. In addition, we clarified that our Board of Directors oversees our programs related to matters of corporate responsibility and sustainability performance, including climate change, through the Nominating and Corporate Governance Committee. These actions demonstrate the strength and commitment to sustainability throughout the organization worldwide.

ITEM 1A. | RISK FACTORS

The following risks and uncertainties, as well as others described in this Annual Report on Form 10-K, could materially and adversely affect our business, our results of operations and financial condition and could cause actual results to differ materially from our expectations and projections. Stockholders are cautioned that these and other factors, including those beyond our control, may affect future performance and cause actual results to differ from those which may, from time to time, be anticipated. There may be additional risks that are not presently material or known. See “Cautionary Note Regarding Forward-Looking Statements.” All forward-looking statements made by us or on our behalf are qualified by the risks described below.
We operate in an extremely competitive industry and are subject to pricing pressures.
We compete with a number of major international manufacturers and distributors, as well as a large number of smaller, regional competitors. Due to excess capacity in some sectors of our industry and consolidation among industrial battery purchasers, we have been subjected to significant pricing pressures. We anticipate continued competitive pricing pressure as foreign producers are able to employ labor at significantly lower costs than producers in the U.S. and Western Europe, expand their export capacity and increase their marketing presence in our major Americas and European markets. Several of our competitors have strong technical, marketing, sales, manufacturing, distribution and other resources, as well as significant name recognition, established positions in the market and long-standing relationships with OEMs and other customers. In addition, certain of our competitors own lead smelting facilities which, during periods of lead cost increases or price volatility, may provide a competitive pricing advantage and reduce their exposure to volatile raw material costs. Our ability to maintain and improve our operating margins has depended, and continues to depend, on our ability to control and reduce our costs. We cannot assure you that we will be able to continue to control our operating expenses, to raise or maintain our prices or increase our unit volume, in order to maintain or improve our operating results.
Our results of operations may be negatively impacted by public health epidemics or outbreaks, including the novel coronavirus (“COVID-19”).
Public health epidemics or outbreaks could adversely impact our business. In December 2019, a novel strain of coronavirus (COVID-19) emerged in Wuhan, Hubei Province, China. While initially the outbreak was largely concentrated in China, infections have been reported globally and causing disruption to many economies. The extent to which the coronavirus continues to impact our operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration of the outbreak, new information which may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, as well as the distribution and effectiveness of COVID-19 vaccines, among others. In particular, the continued spread of the coronavirus globally could adversely impact our operations, including among others, our manufacturing and supply chain, sales and marketing and could have an adverse impact on our business and our financial results. Additionally, countries may impose prolonged quarantines and travel restrictions, which may significantly impact the ability of our employees to get to their places of work to produce products, may make it such that we are unable to obtain sufficient components or raw materials and component parts on a timely basis or at a cost-effective price or may significantly hamper our products from moving through the supply chain.
Our global operations expose us to risks associated with public health crises and epidemics/pandemics, such as COVID-19. We rely on our production facilities, as well as third-party suppliers and manufacturers, in the United States, Australia, Canada, France, Germany, Italy, the People's Republic of China (“PRC”), the United Kingdom and other countries significantly impacted by COVID-19. This outbreak has resulted in the extended shutdown of certain businesses in many of these countries, which has resulted and may continue to result in disruptions or delays to our supply chain. Any disruption in these businesses will likely impact our sales and operating results. COVID-19 has had, and may continue to have, an adverse impact on our operations, supply chains and distribution systems and increase our expenses, including as a result of impacts associated with preventive and precautionary measures that we, other businesses and governments are taking. Due to these impacts and measures, we have experienced, and may continue to experience, significant and unpredictable reductions in demand for certain of our products. The degree and duration of disruptions to business activity are unknown at this time. The rapid spread of a contagious illness such as a novel coronavirus, or fear of such an event, can have a material adverse effect on the demand for our products and services and therefore have a material adverse effect on our business and results of operations.
A widespread health crisis could adversely affect the global economy, resulting in an economic downturn that could impact demand for our products.
14

Table of Contents
The future impact of the outbreak is highly uncertain and cannot be predicted and there is no assurance that the outbreak will not have a material adverse impact on our business, financial condition and results of operations. The extent of the impact will depend on future developments, including actions taken to contain COVID-19, and if these impacts persist or exacerbate over an extended period of time.
The uncertainty in global economic conditions could negatively affect the Company’s operating results.
Our operating results are directly affected by the general global economic conditions of the industries in which our major customer groups operate. Our business segments are highly dependent on the economic and market conditions in each of the geographic areas in which we operate. Our products are heavily dependent on the end markets that we serve and our operating results will vary by location, depending on the economic environment in these markets. Sales of our motive power products, for example, depend significantly on demand for new electric industrial forklift trucks, which in turn depends on end-user demand for additional motive capacity in their distribution and manufacturing facilities. The uncertainty in global economic conditions varies by geographic location, and can result in substantial volatility in global credit markets, particularly in the United States, where we service the vast majority of our debt. These conditions affect our business by reducing prices that our customers may be able or willing to pay for our products or by reducing the demand for our products, which could in turn negatively impact our sales and earnings generation and result in a material adverse effect on our business, cash flow, results of operations and financial position.
Government reviews, inquiries, investigations, and actions could harm our business or reputation.
As we operate in various locations around the world, our operations in certain countries are subject to significant governmental scrutiny and may be adversely impacted by the results of such scrutiny. The regulatory environment with regard to our business is evolving, and officials often exercise broad discretion in deciding how to interpret and apply applicable regulations. From time to time, we receive formal and informal inquiries from various government regulatory authorities, as well as self-regulatory organizations, about our business and compliance with local laws, regulations or standards.
Any determination that our operations or activities, or the activities of our employees, are not in compliance with existing laws, regulations or standards could result in the imposition of substantial fines, interruptions of business, loss of supplier, vendor, customer or other third-party relationships, termination of necessary licenses and permits, or similar results, all of which could potentially harm our business and/or reputation. Even if an inquiry does not result in these types of determinations, regulatory authorities could cause us to incur substantial costs or require us to change our business practices in a manner materially adverse to our business, and it potentially could create negative publicity which could harm our business and/or reputation.
Reliance on third party relationships and derivative agreements could adversely affect the Company’s business.
We depend on third parties, including suppliers, distributors, lead toll operators, freight forwarders, insurance brokers, commodity brokers, major financial institutions and other third party service providers, for key aspects of our business, including the provision of derivative contracts to manage risks of (a) commodity cost volatility, (b) foreign currency exposures and (c) interest rate volatility. Failure of these third parties to meet their contractual, regulatory and other obligations to the Company, or the development of factors that materially disrupt our relationships with these third parties, could expose us to the risks of business disruption, higher commodity and interest costs, unfavorable foreign currency rates and higher expenses, which could have a material adverse effect on our business.
Our operating results could be adversely affected by changes in the cost and availability of raw materials.
Lead is our most significant raw material and is used along with significant amounts of plastics, steel, copper and other materials in our manufacturing processes. We estimate that raw material costs account for over half of our cost of goods sold. The costs of these raw materials, particularly lead, are volatile and beyond our control. Additionally, availability of the raw materials used to manufacture our products may be limited at times resulting in higher prices and/or the need to find alternative suppliers. Furthermore, the cost of raw materials may also be influenced by transportation costs. Volatile raw material costs can significantly affect our operating results and make period-to-period comparisons extremely difficult. We cannot assure you that we will be able to either hedge the costs or secure the availability of our raw material requirements at a reasonable level or, even with respect to our agreements that adjust pricing to a market-based index for lead, pass on to our customers the increased costs of our raw materials without affecting demand or that limited availability of materials will not impact our production capabilities. Our inability to raise the price of our products in response to increases in prices of raw materials or to maintain a proper supply of raw materials could have an adverse effect on our revenue, operating profit and net income.

Increases in costs, disruption of supply or shortage of any of our battery components, such as electronic and mechanical parts, or raw materials used in the production of such parts could harm our business.
From time to time, we may experience increases in the cost or a sustained interruption in the supply or shortage of our components. For example, a global shortage and component supply disruptions of electronic battery components is currently being reported, and the full impact to us is yet unknown. Other examples of shortages and component supply disruptions could include the supply of electronic components and raw materials (such as resins and other raw metal materials) that go into the production of our components. Any such cost increase or supply interruption could materially and negatively impact our business, prospects, financial condition and operating results. The prices for our components fluctuate depending on market conditions and global demand and could adversely affect our business, prospects, financial condition and operating results. For instance, we are exposed to multiple risks relating to price fluctuations for battery cells. These risks include, but are not limited to:
•supply shortages caused by the inability or unwillingness of our suppliers and their competitors to build or operate component production facilities to supply the numbers of battery components required to support the rapid growth of the electric vehicle industry and other industries in which we operate as demand for such components increases;
•disruption in the supply of electronic circuits due to quality issues or insufficient raw materials;
•a decrease in the number of manufacturers of battery components; and
•an increase in the cost of raw materials.
We are dependent on the continued supply of battery components for our products. We have, to date, fully qualified only a very limited number of such suppliers and have limited flexibility in changing suppliers, though we are actively engaged in activities to qualify additional suppliers. Any disruption in the supply of battery components could temporarily disrupt production of our products until a different supplier is fully qualified.
The cost of our battery products depends in part upon the prices and availability of raw materials such as lithium, nickel, cobalt and/or other metals. The prices for these materials fluctuate and their available supply may be unstable, depending on market conditions and global demand for these materials, including as a result of increased global production of electric vehicles and energy storage products. Furthermore, fluctuations or shortages in petroleum and other economic conditions may cause us to experience significant increases in freight charges. Any reduced availability of these raw materials or substantial increases in the prices for such materials may increase the cost of our components and consequently, the cost of our products. There can be no assurance that we will be able to recoup increasing costs of our components by increasing prices, which in turn could damage our brand, business, prospects, financial condition and operating results.
Our operations expose us to litigation, tax, environmental and other legal compliance risks.
We are subject to a variety of litigation, tax, environmental, health and safety and other legal compliance risks. These risks include, among other things, possible liability relating to product liability matters, personal injuries, intellectual property rights, contract-related claims, government contracts, taxes, health and safety liabilities, environmental matters and compliance with U.S. and foreign laws, competition laws and laws governing improper business practices. We or one of our business units could be charged with wrongdoing as a result of such matters. If convicted or found liable, we could be subject to significant fines, penalties, repayments or other damages (in certain cases, treble damages). As a global business, we are subject to complex laws and regulations in the U.S. and other countries in which we operate. Those laws and regulations may be interpreted in different ways. They may also change from time to time, as may related interpretations and other guidance. Changes in laws or regulations could result in higher expenses and payments, and uncertainty relating to laws or regulations may also affect how we conduct our operations and structure our investments and could limit our ability to enforce our rights.
In the area of taxes, changes in tax laws and regulations, as well as changes in related interpretations and other tax guidance could materially impact our tax receivables and liabilities and our deferred tax assets and tax liabilities. Additionally, in the ordinary course of business, we are subject to examinations by various authorities, including tax authorities. In addition to ongoing examinations, there could be additional investigations launched in the future by governmental authorities in various jurisdictions and existing investigations could be expanded. The global and diverse nature of our operations means that these risks will continue to exist and additional legal proceedings and contingencies will arise from time to time. Our results may be affected by the outcome of legal proceedings and other contingencies that cannot be predicted with certainty.
In the manufacture of our products throughout the world, we process, store, dispose of and otherwise use large amounts of hazardous materials, especially lead and acid. As a result, we are subject to extensive and changing environmental, health and safety laws and regulations governing, among other things: the generation, handling, storage, use, transportation and disposal of
16

Table of Contents
hazardous materials; remediation of polluted ground or water; emissions or discharges of hazardous materials into the ground, air or water; and the health and safety of our employees. In light of the efforts to slow the spread of COVID-19 by many governments, we have also become subject to a number of restrictions on the operation of our business. Compliance with these laws and regulations results in ongoing costs. Failure to comply with these laws or regulations, or to obtain or comply with required environmental permits, could result in fines, criminal charges or other sanctions by regulators. From time to time we have had instances of alleged or actual noncompliance that have resulted in the imposition of fines, penalties and required corrective actions. Our ongoing compliance with environmental, health and safety laws, regulations and permits could require us to incur significant expenses, limit our ability to modify or expand our facilities or continue production and require us to install additional pollution control equipment and make other capital improvements. In addition, private parties, including current or former employees, could bring personal injury or other claims against us due to the presence of, or exposure to, hazardous substances used, stored or disposed of by us or contained in our products.
Certain environmental laws assess liability on owners or operators of real property for the cost of investigation, removal or remediation of hazardous substances at their current or former properties or at properties at which they have disposed of hazardous substances. These laws may also assess costs to repair damage to natural resources. We may be responsible for remediating damage to our properties caused by former owners. Soil and groundwater contamination has occurred at some of our current and former properties and may occur or be discovered at other properties in the future. We are currently investigating and monitoring soil and groundwater contamination at several of our properties, in most cases as required by regulatory permitting processes. We may be required to conduct these operations at other properties in the future. In addition, we have been, and in the future, may be liable to contribute to the cleanup of locations owned or operated by other persons to which we or our predecessor companies have sent wastes for disposal, pursuant to federal and other environmental laws. Under these laws, the owner or operator of contaminated properties and companies that generated, disposed of or arranged for the disposal of wastes sent to a contaminated disposal facility can be held jointly and severally liable for the investigation and cleanup of such properties, regardless of fault. Additionally, our products may become subject to fees and taxes in order to fund cleanup of such properties, including those operated or used by other lead-battery industry participants.
Changes in environmental and climate laws or regulations could lead to new or additional investment in production designs and could increase environmental compliance expenditures. For example, the European Union has enacted greenhouse gas emissions legislation, and continues to expand the scope of such legislation. The United States Environmental Protection Agency has promulgated regulations applicable to projects involving greenhouse gas emissions above a certain threshold, and the United States and certain states within the United States have enacted, or are considering, limitations on greenhouse gas emissions.
Changes in climate change concerns, or in the regulation of such concerns, including greenhouse gas emissions, could subject us to additional costs and restrictions, including increased energy and raw materials costs. Additionally, we cannot assure you that we have been or at all times will be in compliance with environmental laws and regulations or that we will not be required to expend significant funds to comply with, or discharge liabilities arising under, environmental laws, regulations and permits, or that we will not be exposed to material environmental, health or safety litigation.
Also, the U.S. Foreign Corrupt Practices Act (“FCPA”) and similar worldwide anti-bribery laws in non-U.S. jurisdictions generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. The FCPA applies to companies, individual directors, officers, employees and agents. Under the FCPA, U.S. companies may be held liable for actions taken by strategic or local partners or representatives. The FCPA also imposes accounting standards and requirements on publicly traded U.S. corporations and their foreign affiliates, which are intended to prevent the diversion of corporate funds to the payment of bribes and other improper payments. Certain of our customer relationships outside of the U.S. are with governmental entities and are therefore subject to such anti-bribery laws. Our policies mandate compliance with these anti-bribery laws. Despite meaningful measures that we undertake to facilitate lawful conduct, which include training and internal control policies, these measures may not always prevent reckless or criminal acts by our employees or agents. As a result, we could be subject to criminal and civil penalties, disgorgement, further changes or enhancements to our procedures, policies and controls, personnel changes or other remedial actions. Violations of these laws, or allegations of such violations, could disrupt our operations, involve significant management distraction and result in a material adverse effect on our competitive position, results of operations, cash flows or financial condition.
There is also a regulation to improve the transparency and accountability concerning the supply of minerals coming from the conflict zones in and around the Democratic Republic of Congo. U.S. legislation included disclosure requirements regarding the use of conflict minerals mined from the Democratic Republic of Congo and adjoining countries and procedures regarding a manufacturer’s efforts to prevent the sourcing of such conflict minerals. In addition, the European Union adopted an EU-wide conflict minerals rule under which most EU importers of tin, tungsten, tantalum, gold and their ores will have to conduct due
17

Table of Contents
diligence to ensure the minerals do not originate from conflict zones and do not fund armed conflicts. Large manufacturers also will have to disclose how they plan to monitor their sources to comply with the rules. Compliance with the regulation began January 1, 2021. The implementation of these requirements could affect the sourcing and availability of minerals used in the manufacture of our products. As a result, there may only be a limited pool of suppliers who provide conflict-free metals, and we cannot assure you that we will be able to obtain products in sufficient quantities or at competitive prices. Future regulations may become more stringent or costly and our compliance costs and potential liabilities could increase, which may harm our business.
We are exposed to exchange rate risks, and our net earnings and financial condition may suffer due to currency translations.
We invoice our foreign sales and service transactions in local and foreign currencies and translate net sales using actual exchange rates during the period. We translate our non-U.S. assets and liabilities into U.S. dollars using current exchange rates as of the balance sheet dates. Because a significant portion of our revenues and expenses are denominated in foreign currencies, changes in exchange rates between the U.S. dollar and foreign currencies, primarily the euro, British pound, Polish zloty, Chinese renminbi, Mexican peso and Swiss franc may adversely affect our revenue, cost of goods sold and operating margins. For example, foreign currency depreciation against the U.S. dollar will reduce the value of our foreign revenues and operating earnings as well as reduce our net investment in foreign subsidiaries. Approximately 40% of net sales were generated outside of the United States in fiscal 2021.
Most of the risk of fluctuating foreign currencies is in our European operations, which comprised approximately one-third of our net sales during the last three fiscal years. The euro is the dominant currency in our EMEA operations. In the event that one or more European countries were to replace the euro with another currency, our sales into such countries, or into Europe generally, would likely be adversely affected until stable exchange rates are established.
The translation impact from currency fluctuations on net sales and operating earnings in our Americas and Asia operations are not as significant as our European operations, as a substantial majority of these net sales and operating earnings are in U.S. dollars or foreign currencies that have been closely correlated to the U.S. dollar.
If foreign currencies depreciate against the U.S. dollar, it would make it more expensive for our non-U.S. subsidiaries to purchase certain of our raw material commodities that are priced globally in U.S. dollars, while the related revenue will decrease when translated to U.S. dollars. Significant movements in foreign exchange rates can have a material impact on our results of operations and financial condition. We periodically engage in hedging of our foreign currency exposures, but cannot assure you that we can successfully hedge all of our foreign currency exposures or do so at a reasonable cost.
We quantify and monitor our global foreign currency exposures. Our largest foreign currency exposure is from the purchase and conversion of U.S. dollar-based lead costs into local currencies in Europe. Additionally, we have currency exposures from intercompany financing and intercompany and third party trade transactions. On a selective basis, we enter into foreign currency forward contracts and purchase option contracts to reduce the impact from the volatility of currency movements; however, we cannot be certain that foreign currency fluctuations will not impact our operations in the future.
If we are unable to effectively hedge against currency fluctuations, our operating costs and revenues in our non-U.S. operations may be adversely affected, which would have an adverse effect on our operating profit and net income.
We have experienced and may continue to experience, difficulties implementing our new global enterprise resource planning system.
We are engaged in a multi-year implementation of a new global enterprise resource planning system (“ERP”). The ERP is designed to efficiently maintain our financial records and provide information important to the operation of our business to our management team. The ERP will continue to require significant investment of human and financial resources. In implementing the ERP, we have experienced significant production and shipping delays, increased costs and other difficulties. Any significant disruption or deficiency in the design and implementation of the ERP will adversely affect our ability to process orders, ship product, send invoices and track payments, fulfill contractual obligations or otherwise operate our business. While we have invested significant resources in planning, project management and training, additional and significant implementation issues may arise. In addition, our efforts to centralize various business processes and functions within our organization in connection with our ERP implementation may disrupt our operations and negatively impact our business, results of operations and financial condition.

The failure to successfully implement efficiency and cost reduction initiatives, including restructuring activities, could materially adversely affect our business and results of operations, and we may not realize some or all of the anticipated benefits of those initiatives.
From time to time we have implemented efficiency and cost reduction initiatives intended to improve our profitability and to respond to changes impacting our business and industry. These initiatives include relocating manufacturing to lower cost regions, working with our material suppliers to lower costs, product design and manufacturing improvements, personnel reductions and voluntary retirement programs, and strategically planning capital expenditures and development activities. In the past we have recorded net restructuring charges to cover costs associated with our cost reduction initiatives involving restructuring. These costs have been primarily composed of employee separation costs, including severance payments, and asset impairments or losses from disposal. We also undertake restructuring activities and programs to improve our cost structure in connection with our business acquisitions, which can result in significant charges, including charges for severance payments to terminated employees and asset impairment charges.
We cannot assure you that our efficiency and cost reduction initiatives will be successfully or timely implemented, or that they will materially and positively impact our profitability. Because our initiatives involve changes to many aspects of our business, the associated cost reductions could adversely impact productivity and sales to an extent we have not anticipated. In addition, our ability to complete our efficiency and cost-savings initiatives and achieve the anticipated benefits within the expected time frame is subject to estimates and assumptions and may vary materially from our expectations, including as a result of factors that are beyond our control. Furthermore, our efforts to improve the efficiencies of our business operations and improve growth may not be successful. Even if we fully execute and implement these activities and they generate the anticipated cost savings, there may be other unforeseeable and unintended consequences that could materially adversely impact our profitability and business, including unintended employee attrition or harm to our competitive position. To the extent that we do not achieve the profitability enhancement or other benefits of our efficiency and cost reduction initiatives that we anticipate, our results of operations may be materially adversely affected.
Our international operations may be adversely affected by actions taken by foreign governments or other forces or events over which we may have no control.
We currently have significant manufacturing and/or distribution facilities outside of the United States, in Argentina, Australia, Belgium, Brazil, Canada, the Czech Republic, France, Germany, India, Italy, Malaysia, Mexico, the PRC, Poland, Spain, Switzerland and the United Kingdom. Our global operations are dependent upon products manufactured, purchased and sold in the U.S. and internationally, including in countries with political and economic instability or uncertainty. This includes, for example, the uncertainty related to the United Kingdom’s withdrawal from the European Union (commonly known as “Brexit”) and the adoption and expansion of trade restrictions, including the occurrence or escalation of a "trade war," or other governmental action related to tariffs or trade agreements or policies among the governments of the United States, the PRC and other countries. On January 31, 2020, the United Kingdom left the European Union pursuant to a withdrawal agreement which provides for, among other things, a transition period ending on December 31, 2020 during which the United Kingdom will remain (i) subject to all European Union laws and all international agreements that the European Union has signed and (ii) in the European Union Customs Union and the European Union Single Market.
Some countries have greater political and economic volatility and greater vulnerability to infrastructure and labor disruptions than others. Our business could be negatively impacted by adverse fluctuations in freight costs, limitations on shipping and receiving capacity, and other disruptions in the transportation and shipping infrastructure at important geographic points of exit and entry for our products. Operating in different regions and countries exposes us to a number of risks, including:
•multiple and potentially conflicting laws, regulations and policies that are subject to change;
•imposition of currency restrictions, restrictions on repatriation of earnings or other restraints imposition of burdensome import duties, tariffs or quotas;
•changes in trade agreements;
•imposition of new or additional trade and economic sanctions laws imposed by the U.S. or foreign governments;
•war or terrorist acts; and
•political and economic instability or civil unrest that may severely disrupt economic activity in affected countries.
The occurrence of one or more of these events may negatively impact our business, results of operations and financial condition.
Our failure to introduce new products and product enhancements and broad market acceptance of new technologies introduced by our competitors could adversely affect our business.
19

Table of Contents
Many new energy storage technologies have been introduced over the past several years. For certain important and growing markets, such as aerospace and defense, lithium-based battery technologies have a large and growing market share. Our ability to achieve significant and sustained penetration of key developing markets, including aerospace and defense, will depend upon our success in developing or acquiring these and other technologies, either independently, through joint ventures or through acquisitions. If we fail to develop or acquire, and manufacture and sell, products that satisfy our customers’ demands, or we fail to respond effectively to new product announcements by our competitors by quickly introducing competitive products, then market acceptance of our products could be reduced and our business could be adversely affected. We cannot assure you that our portfolio of primarily lead-acid products will remain competitive with products based on new technologies.
We may not be able to adequately protect our proprietary intellectual property and technology.
We rely on a combination of copyright, trademark, patent and trade secret laws, non-disclosure agreements and other confidentiality procedures and contractual provisions to establish, protect and maintain our proprietary intellectual property and technology and other confidential information. Certain of these technologies, especially TPPL technology, are important to our business and are not protected by patents. Despite our efforts to protect our proprietary intellectual property and technology and other confidential information, unauthorized parties may attempt to copy or otherwise obtain and use our intellectual property and proprietary technologies. If we are unable to protect our intellectual property and technology, we may lose any technological advantage we currently enjoy and may be required to take an impairment charge with respect to the carrying value of such intellectual property or goodwill established in connection with the acquisition thereof. In either case, our operating results and net income may be adversely affected.
Relocation of our customers’ operations could adversely affect our business.
The trend by a number of our North American and Western European customers to move manufacturing operations and expand their businesses in faster growing and low labor-cost markets may have an adverse impact on our business. As our customers in traditional manufacturing-based industries seek to move their manufacturing operations to these locations, there is a risk that these customers will source their energy storage products from competitors located in those territories and will cease or reduce the purchase of products from our manufacturing plants. We cannot assure you that we will be able to compete effectively with manufacturing operations of energy storage products in those territories, whether by establishing or expanding our manufacturing operations in those lower-cost territories or acquiring existing manufacturers.
Quality problems with our products could harm our reputation and erode our competitive position.
The success of our business will depend upon the quality of our products and our relationships with customers. In the event that our products fail to meet our customers’ standards, our reputation could be harmed, which would adversely affect our marketing and sales efforts. We cannot assure you that our customers will not experience quality problems with our products.
We offer our products under a variety of brand names, the protection of which is important to our reputation for quality in the consumer marketplace.
We rely upon a combination of trademark, licensing and contractual covenants to establish and protect the brand names of our products. We have registered many of our trademarks in the U.S. Patent and Trademark Office and in other countries. In many market segments, our reputation is closely related to our brand names. Monitoring unauthorized use of our brand names is difficult, and we cannot be certain that the steps we have taken will prevent their unauthorized use, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the U.S. We cannot assure you that our brand names will not be misappropriated or utilized without our consent or that such actions will not have a material adverse effect on our reputation and on our results of operations.
We may fail to implement our plans to make acquisitions or successfully integrate them into our operations.
As part of our business strategy, we have grown, and plan to continue growing, by acquiring other product lines, technologies or facilities that complement or expand our existing business, such as the acquisition of NorthStar during fiscal 2020. There is significant competition for acquisition targets in the stored energy industry. We may not be able to identify suitable acquisition candidates or negotiate attractive terms. In addition, we may have difficulty obtaining the financing necessary to complete transactions we pursue. In that regard, our credit facilities restrict the amount of additional indebtedness that we may incur to finance acquisitions and place other restrictions on our ability to make acquisitions. Exceeding any of these restrictions would require the consent of our lenders. Even if acquisition candidates are identified, we cannot be sure that our diligence will
20

Table of Contents
surface all material issues that may be present, including as they relate to inside NorthStar or its business, or that it would be possible to uncover all material issues through a customary amount of due diligence, or that factors outside of such acquisition candidate, NorthStar and its business and outside of their respective control will not arise later. If any such material issues arise, they may materially and adversely impact the on-going business of EnerSys and our stockholders’ investment. We may be unable to successfully integrate any assets, liabilities, customers, systems and management personnel we acquire into our operations and we may not be able to realize related revenue synergies and cost savings within expected time frames. For example, the ability of EnerSys to realize the anticipated benefits of the NorthStar acquisition will depend, to a large extent, on our ability to combine NorthStar's and our businesses in a manner that facilitates growth opportunities and realizes anticipated synergies, and achieves the projected stand-alone cost savings and revenue growth trends identified by each company. It is expected that we will benefit from operational and general and administrative cost synergies resulting from the warehouse and transportation integration, direct procurement savings on overlapping materials, purchasing scale on indirect spend categories and optimization of duplicate positions and processes. We may also enjoy revenue synergies, driven by a strong portfolio of brands with exposure to higher growth segments and the ability to leverage our collective distribution strength. In order to achieve these expected benefits, we must successfully combine the businesses of NorthStar and EnerSys in a manner that permits these cost savings and synergies to be realized and must achieve the anticipated savings and synergies without adversely affecting current revenues and investments in future growth. If we experience difficulties with the integration process or are not able to successfully achieve these objectives, the anticipated benefits of the NorthStar acquisition may not be realized fully or at all or may take longer to realize than expected. Our failure to execute our acquisition strategy could have a material adverse effect on our business. We cannot assure you that our acquisition strategy will be successful or that we will be able to successfully integrate acquisitions we do make.
Any acquisitions that we complete may dilute stockholder ownership interests in EnerSys, may have adverse effects on our financial condition and results of operations and may cause unanticipated liabilities.
Future acquisitions may involve the issuance of our equity securities as payment, in part or in full, for the businesses or assets acquired. Any future issuances of equity securities would dilute stockholder ownership interests. In addition, future acquisitions might not increase, and may even decrease, our earnings or earnings per share and the benefits derived by us from an acquisition might not outweigh or might not exceed the dilutive effect of the acquisition. We also may incur additional debt or suffer adverse tax and accounting consequences in connection with any future acquisitions.
If our electronic data is compromised, our business could be significantly harmed.
We and our business partners maintain significant amounts of data electronically in locations around the world. This data relates to all aspects of our business, including current and future products and services under development, and also contains certain customer, supplier, partner and employee data. We maintain systems and processes designed to protect this data, but notwithstanding such protective measures, there is a risk of intrusion, cyberattacks, tampering, theft, misplaced or lost data, programming and/or human errors that could compromise the integrity and privacy of this data, improper use of our systems, software solutions or networks, unauthorized access, use, disclosure, modification or destruction of information, defective products, production downtimes and operational disruptions, which in turn could adversely affect our reputation, competitiveness, and results of operations. In addition, we provide confidential and proprietary information to our third-party business partners in certain cases where doing so is necessary to conduct our business. While we obtain assurances from those parties that they have systems and processes in place to protect such data, and where applicable, that they will take steps to assure the protections of such data by third parties, nonetheless those partners may also be subject to data intrusion or otherwise compromise the protection of such data. Any compromise of the confidential data of our customers, suppliers, partners, employees or ourselves, or failure to prevent or mitigate the loss of or damage to this data through breach of our information technology systems or other means could substantially disrupt our operations, harm our customers, employees and other business partners, damage our reputation, violate applicable laws and regulations, subject us to potentially significant costs and liabilities and result in a loss of business that could be material.
We operate a number of critical computer systems throughout our business that can fail for a variety of reasons. If such a failure were to occur, we may not be able to sufficiently recover from the failure in time to avoid the loss of data or any adverse impact on certain of our operations that are dependent on such systems. This could result in lost sales and the inefficient operation of our facilities for the duration of such a failure.
We may not be able to maintain adequate credit facilities.
Our ability to continue our ongoing business operations and fund future growth depends on our ability to maintain adequate credit facilities and to comply with the financial and other covenants in such credit facilities or to secure alternative sources of
21

Table of Contents
financing. However, such credit facilities or alternate financing may not be available or, if available, may not be on terms favorable to us. If we do not have adequate access to credit, we may be unable to refinance our existing borrowings and credit facilities when they mature and to fund future acquisitions, and this may reduce our flexibility in responding to changing industry conditions.
Our indebtedness could adversely affect our financial condition and results of operations.
As of March 31, 2021, we had $1,004 million of total consolidated debt (including finance leases). This level of debt could:
•increase our vulnerability to adverse general economic and industry conditions, including interest rate fluctuations, because a portion of our borrowings bear, and will continue to bear, interest at floating rates;
•require us to dedicate a substantial portion of our cash flow from operations to debt service payments, which would reduce the availability of our cash to fund working capital, capital expenditures or other general corporate purposes, including acquisitions;
•limit our flexibility in planning for, or reacting to, changes in our business and industry;
•restrict our ability to introduce new products or new technologies or exploit business opportunities;
•place us at a disadvantage compared with competitors that have proportionately less debt;
•limit our ability to borrow additional funds in the future, if we need them, due to financial and restrictive covenants in our debt agreements; and
•have a material adverse effect on us if we fail to comply with the financial and restrictive covenants in our debt agreements.
There can be no assurance that we will continue to declare cash dividends at all or in any particular amounts.
During fiscal 2021, we announced the declaration of a quarterly cash dividend of $0.175 per share of common stock for quarters ended July 5, 2020, October 4, 2020, January 3, 2021 and March 31, 2021. On May 20, 2021, we announced a fiscal 2022 first quarter cash dividend of $0.175 per share of common stock. Future payment of a regular quarterly cash dividend on our common shares will be subject to, among other things, our results of operations, cash balances and future cash requirements, financial condition, statutory requirements of Delaware law, compliance with the terms of existing and future indebtedness and credit facilities, and other factors that the Board of Directors may deem relevant. Our dividend payments may change from time to time, and we cannot provide assurance that we will continue to declare dividends at all or in any particular amounts. A reduction in or elimination of our dividend payments could have a negative effect on our share price.
We cannot guarantee that our share repurchase programs will be fully consummated or that they will enhance long-term stockholder value. Share repurchases could also increase the volatility of the trading price of our stock and could diminish our cash reserves.
Our Board of Directors has authorized two share repurchase programs, one authorizing the repurchase of up to $100 million of our common stock, of which authority, as of March 31, 2021, approximately $59 million remains available and another authorizing the repurchase of up to such number of shares as shall equal the dilutive effects of any equity-based award granted during such fiscal year and the number of shares exercised through stock option awards during such fiscal year. Although our board of directors has authorized these share repurchase programs, the programs do not obligate us to repurchase any specific dollar amount or to acquire any specific number of shares. We cannot guarantee that the programs will be fully consummated or that they will enhance long-term stockholder value. The programs could affect the trading price of our stock and increase volatility, and any announcement of a termination of these programs may result in a decrease in the trading price of our stock. In addition, these programs could diminish our cash reserves.
We depend on our senior management team and other key employees, and significant attrition within our management team or unsuccessful succession planning could adversely affect our business.
Our success depends in part on our ability to attract, retain and motivate senior management and other key employees. Achieving this objective may be difficult due to many factors, including fluctuations in global economic and industry conditions, competitors’ hiring practices, cost reduction activities, and the effectiveness of our compensation programs. Competition for qualified personnel can be very intense. We must continue to recruit, retain and motivate senior management and other key employees sufficient to maintain our current business and support our future projects. We are vulnerable to attrition among our current senior management team and other key employees. A loss of any such personnel, or the inability to recruit and retain qualified personnel in the future, could have an adverse effect on our business, financial condition and results
22

Table of Contents
of operations. In addition, if we are unsuccessful in our succession planning efforts, the continuity of our business and results of operations could be adversely affected.
We may have exposure to greater than anticipated tax liabilities.
Our income tax obligations are based in part on our corporate operating structure and intercompany arrangements, including the manner in which we operate our business, develop, value, manage, protect, and use our intellectual property and the valuations of our intercompany transactions. We may also be subject to additional indirect or non-income taxes. The tax laws applicable to our business, including the laws of the United States and other jurisdictions, are subject to interpretation and certain jurisdictions are aggressively interpreting their laws in new ways in an effort to raise additional tax revenue from multi-national companies, like us. The taxing authorities of the jurisdictions in which we operate may challenge our methodologies for valuing developed technology or intercompany arrangements, which could increase our worldwide effective tax rate and harm our financial position, results of operations, and cash flows. Although we believe that our provision for income taxes is reasonable, the ultimate tax outcome may differ from the amounts recorded in our financial statements and may materially affect our financial results in the period or periods for which such determination is made. In addition, our future income tax rates could be adversely affected by earnings being lower than anticipated in jurisdictions that have lower statutory tax rates and higher than anticipated in jurisdictions that have higher statutory tax rates, by changes in the valuation of our deferred tax assets and liabilities, or by changes in tax laws, regulations, or accounting principles.
Changes in tax laws or tax rulings could materially affect our financial position, results of operations, and cash flows.
The income and non-income tax regimes we are subject to or operate under are unsettled and may be subject to significant change. Changes in tax laws or tax rulings, or changes in interpretations of existing laws, could materially affect our financial position, results of operations, and cash flows. For example, changes to U.S. tax laws enacted in December 2017 had a significant impact on our tax obligations and effective tax rate beginning 2018. In fiscal year 2020, Switzerland enacted the Federal Act on Tax Reform and AHV (Old-Age and Survivors Insurance) Financing (TRAF) which became effective on January 1, 2020. These enactments and future possible guidance from the applicable taxing authorities may have a material impact on the Company’s operating results. In addition, many countries in Europe, as well as a number of other countries and organizations, have recently proposed or recommended changes to existing tax laws or have enacted new laws that could significantly increase our tax obligations in many countries where we do business or require us to change the manner in which we operate our business. The Company closely monitors these proposals as they arise in the countries where it operates. Changes to the statutory tax rate may occur at any time, and any related expense or benefit recorded may be material to the fiscal quarter and year in which the law change is enacted. The European Commission has conducted investigations in multiple countries focusing on whether local country tax rulings or tax legislation provides preferential tax treatment that violates European Union state aid rules and concluded that certain countries, have provided illegal state aid in certain cases. These investigations may result in changes to the tax treatment of our foreign operations. Due to the large and expanding scale of our international business activities, many of these types of changes to the taxation of our activities could increase our worldwide effective tax rate and harm our financial position, results of operations, and cash flows.
In connection with the Organization for Economic Cooperation and Development Base Erosion and Profit Shifting (BEPS) project, companies are required to disclose more information to tax authorities on operations around the world, which may lead to greater audit scrutiny of profits earned in other countries. The Company regularly assesses the likely outcomes of its tax audits and disputes to determine the appropriateness of its tax reserves. However, any tax authority could take a position on tax treatment that is contrary to the Company’s expectations, which could result in tax liabilities in excess of reserves.
Our software and related services are highly technical and may contain undetected software bugs or vulnerabilities, which could manifest in ways that could seriously harm our reputation and our business.
The software and related services that we offer, including those as a result of the Alpha acquisition, are highly technical and complex. Our services or any other products that we may introduce in the future may contain undetected software bugs, hardware errors, and other vulnerabilities. These bugs and errors can manifest in any number of ways in our products, including through diminished performance, security vulnerabilities, malfunctions, or even permanently disabled products. We have a practice of regularly updating our products and some errors in our products may be discovered only after a product has been used by users, and may in some cases be detected only under certain circumstances or after extended use. Any errors, bugs or other vulnerabilities discovered in our code or backend after release could damage our reputation, drive away users, allow third parties to manipulate or exploit our software, lower revenue and expose us to claims for damages, any of which could seriously
23

Table of Contents
harm our business. Additionally, errors, bugs, or other vulnerabilities may, either directly or if exploited by third parties, affect our ability to make accurate royalty payments.
We also could face claims for product liability, tort or breach of warranty. Defending a lawsuit, regardless of its merit, is costly and may divert management’s attention and seriously harm our reputation and our business. In addition, if our liability insurance coverage proves inadequate or future coverage is unavailable on acceptable terms or at all, our business could be seriously harmed.
A failure to keep pace with developments in technology could impair our operations or competitive position.
Our business continues to demand the use of sophisticated systems and technology. These systems and technologies must be refined, updated and replaced with more advanced systems on a regular basis in order for us to meet our customers’ demands and expectations. If we are unable to do so on a timely basis or within reasonable cost parameters, or if we are unable to appropriately and timely train our employees to operate any of these new systems, our business could suffer. We also may not achieve the benefits that we anticipate from any new system or technology, such as fuel abatement technologies, and a failure to do so could result in higher than anticipated costs or could impair our operating results.

Market Information
The Company’s common stock has been listed on the New York Stock Exchange under the symbol “ENS” since it began trading on July 30, 2004. Prior to that time, there had been no public market for our common stock.
Holders of Record
As of May 21, 2021, there were approximately 497 record holders of common stock of the Company. Because many of these shares are held by brokers and other institutions on behalf of stockholders, the Company is unable to estimate the total number of stockholders represented by these record holders.
Recent Sales of Unregistered Securities
During the fourth quarter of fiscal 2021, we did not issue any unregistered securities.
Dividends
During fiscal 2021, the Company’s quarterly dividend was $0.175 per share. The Company declared aggregate regular cash dividends of $0.70 per share in each of the years ended March 31, 2021, March 31, 2020 and 2019.
The Company anticipates that it will continue to pay quarterly cash dividends in the future. However, the payment and amount of future dividends remain within the discretion of the Board and will depend upon the Company's future earnings, financial condition, capital requirements, restrictions under existing or future credit facilities or debt and other factors. See “There can be no assurance that we will continue to declare cash dividends at all or in any particular amounts.” Under Item 1A. Risk Factors for additional information.

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

The following discussion and analysis of our results of operations and financial condition for the fiscal years ended March 31, 2021, 2020 and 2019, should be read in conjunction with our audited Consolidated Financial Statements and the notes to those statements included in Item 8. Financial Statements and Supplementary Data, of this Annual Report on Form 10-K. Our discussion contains forward-looking statements based upon current expectations that involve risks and uncertainties, such as our plans, objectives, opinions, expectations, anticipations and intentions and beliefs. Actual results and the timing of events could differ materially from those anticipated in those forward-looking statements as a result of a number of factors. See “Cautionary Note Regarding Forward-Looking Statements,” “Business” and “Risk Factors,” sections elsewhere in this Annual Report on Form 10-K. In the following discussion and analysis of results of operations and financial condition, certain financial measures may be considered “non-GAAP financial measures” under the SEC rules. These rules require supplemental explanation and reconciliation, which is provided in this Annual Report on Form 10-K.
EnerSys’ management uses the non-GAAP measures, EBITDA and adjusted EBITDA, in its computation of compliance with loan covenants. These measures, as used by EnerSys, adjust net earnings determined in accordance with GAAP for interest, taxes, depreciation and amortization, and certain charges or credits as permitted by our credit agreements, that were recorded during the periods presented.
EnerSys’ management uses the non-GAAP measures, “free cash flows”, “primary working capital” and “primary working capital percentage” along with capital expenditures, in its evaluation of business segment cash flow and financial position performance. Primary working capital is trade accounts receivable, plus inventories, minus trade accounts payable and the resulting net amount is divided by the trailing three-month net sales (annualized) to derive a primary working capital percentage. Free cash flows are cash flows from operating activities less capital expenditures.
These non-GAAP disclosures have limitations as analytical tools, should not be viewed as a substitute for cash flow or operating earnings determined in accordance with GAAP, and should not be considered in isolation or as a substitute for analysis of the Company’s results as reported under GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. This supplemental presentation should not be construed as an inference that the Company’s future results will be unaffected by similar adjustments to operating earnings determined in accordance with GAAP.
Overview
EnerSys (the “Company,” “we,” or “us”) is a world leader in stored energy solutions for industrial applications. We also manufacture and distribute energy systems solutions and motive power batteries, specialty batteries, battery chargers, power equipment, battery accessories and outdoor equipment enclosure solutions to customers worldwide. Energy Systems which combine enclosures, power conversion, power distribution and energy storage are used in the telecommunication and broadband, utility industries, uninterruptible power supplies, and numerous applications requiring stored energy solutions. Motive Power batteries and chargers are utilized in electric forklift trucks and other industrial electric powered vehicles. Specialty batteries are used in aerospace and defense applications, large over the road trucks, premium automotive and medical. We also provide aftermarket and customer support services to over 10,000 customers in more than 100 countries through a network of distributors, independent representatives and our internal sales force around the world.
During the first quarter of fiscal 2021, the Company's chief operating decision maker, or CODM (the Company's Chief Executive Officer), changed the manner in which he reviews financial information for purposes of assessing business performance and allocating resources, by focusing on the lines of business on a global basis, rather than on geographic basis. As a result of this change, the Company re-evaluated the identification of its operating segments and reportable segments. The new operating segments were identified as Energy Systems, Motive Power and Specialty. The Company’s operating segments also represent its reportable segments under ASC 280, Segment Reporting. Therefore, the Company has changed its segment presentation from three reportable segments based on geographic basis to three reportable segments based on line of business. All prior comparative periods presented have been recast to reflect these changes.
The Company's three reportable segments, based on lines of business, are as follows:
•Energy Systems - uninterruptible power systems, or “UPS” applications for computer and computer-controlled systems, as well as telecommunications systems, switchgear and electrical control systems used in industrial facilities and electric utilities, large-scale energy storage and energy pipelines. Energy Systems also includes highly integrated
30

Table of Contents
power solutions and services to broadband, telecom, renewable and industrial customers, as well as thermally managed cabinets and enclosures for electronic equipment and batteries.
•Motive Power - power for electric industrial forklifts used in manufacturing, warehousing and other material handling applications, as well as mining equipment, diesel locomotive starting and other rail equipment; and
•Specialty - premium starting, lighting and ignition applications in transportation, energy solutions for satellites, military aircraft, submarines, ships and other tactical vehicles, as well as medical and security systems.
We evaluate business segment performance based primarily upon operating earnings exclusive of highlighted items. Highlighted items are those that the Company deems are not indicative of ongoing operating results, including those charges that the Company incurs as a result of restructuring activities, impairment of goodwill and indefinite-lived intangibles and other assets, acquisition activities and those charges and credits that are not directly related to operating unit performance, such as significant legal proceedings, ERP system implementation, amortization of recently acquired intangible assets and tax valuation allowance changes, including those related to the adoption of the Tax Cuts and Jobs Act. Because these charges are not incurred as a result of ongoing operations, or are incurred as a result of a potential or previous acquisition, they are not as helpful a measure of the performance of our underlying business, particularly in light of their unpredictable nature and are difficult to forecast. All corporate and centrally incurred costs are allocated to the business segments based principally on net sales. We evaluate business segment cash flow and financial position performance based primarily upon free cash flows, capital expenditures and primary working capital levels. Although we monitor the three elements of primary working capital (receivables, inventory and payables), our primary focus is on the total amount due to the significant impact it has on our cash flow.
Our management structure, financial reporting systems, and associated internal controls and procedures, are all consistent with our three lines of business. We report on a March 31 fiscal year-end. Our financial results are largely driven by the following factors:
•global economic conditions and general cyclical patterns of the industries in which our customers operate;
•changes in our selling prices and, in periods when our product costs increase, our ability to raise our selling prices to pass such cost increases through to our customers;
•the extent to which we are able to efficiently utilize our global manufacturing facilities and optimize our capacity;
•the extent to which we can control our fixed and variable costs, including those for our raw materials, manufacturing, distribution and operating activities;
•changes in our level of debt and changes in the variable interest rates under our credit facilities; and
•the size and number of acquisitions and our ability to achieve their intended benefits.
Current Market Conditions
Economic Climate
Global economies are recovering differently from the COVID-19 pandemic. The United States and Chinese economies are experiencing a strong recovery while EMEA’s economy continues to be slowed by high levels of COVID-19 cases.
EnerSys is experiencing some supply chain disruptions in certain materials such as plastic resins and electronic components along with occasional transportation challenges. In addition, some locations have difficulty meeting hiring goals. Generally, our mitigation efforts and the recent economic recovery, limit the impact of the pandemic-related challenges.
Volatility of Commodities and Foreign Currencies
Our most significant commodity and foreign currency exposures are related to lead and the Euro, respectively. Historically, volatility of commodity costs and foreign currency exchange rates have caused large swings in our production costs. As a result of the COVID-19 pandemic, lead dropped into the low 70 cents per pound rate during our first fiscal quarter of 2021 and has currently rallied back to the mid 90 cents per pound rate which is approximately the pre-COVID-19 levels. We are experiencing increasing costs in some of our raw materials such as plastic resins, steel, copper and electronics.
Customer Pricing
Our selling prices fluctuated during the last several years to offset the volatile cost of commodities. Approximately 30% of our revenue is now subject to agreements that adjust pricing to a market-based index for lead. Lead prices peaked in the first quarter of fiscal 2019 and then declined sequentially in every quarter in fiscal 2019. In fiscal 2020, our selling prices declined in
31

Table of Contents
response to declining commodity costs, including lead. In fiscal 2021, lead prices declined further in the first quarter and then recovered slowly throughout the rest of the fiscal year. Based on current commodity markets, we will likely see year over year headwinds from increasing commodity prices, with some related increase in our selling prices in the upcoming year. As we concentrate more on energy systems and non-lead chemistries, the emphasis on lead will continue to decline.
Liquidity and Capital Resources
We believe that our financial position is strong, and we have substantial liquidity with $452 million of available cash and cash equivalents and available and undrawn committed credit lines of approximately $698 million at March 31, 2021 to cover short-term liquidity requirements and anticipated growth in the foreseeable future. The nominal amount of credit available is subject to a leverage ratio maximum of 3.5x EBITDA, as discussed in Liquidity and Capital Resources, which effectively limits additional debt or lowered cash balances by approximately $600 million.
In fiscal 2020, we issued $300 million in aggregate principal amount of our 4.375% Senior Notes due 2027 (the “2027 Notes”). Proceeds from this offering, net of debt issuance costs were $296.3 million and were utilized to pay down the balance outstanding on the revolver borrowings.
In fiscal 2018, we entered into a credit facility (“2017 Credit Facility”) that consisted of a $600.0 million senior secured revolving credit facility (“2017 Revolver”) and a $150.0 million senior secured term loan (“2017 Term Loan”) with a maturity date of September 30, 2022. On December 7, 2018, we amended the 2017 Credit Facility (as amended, the “Amended Credit Facility”). The Amended Credit Facility consists of $449.1 million senior secured term loans (the “Amended 2017 Term Loan”), including a CAD 133.1 million ($99.1 million) term loan and a $700.0 million senior secured revolving credit facility (the “Amended 2017 Revolver”). The amendment resulted in an increase of the 2017 Term Loan and the 2017 Revolver by $299.1 million and $100.0 million, respectively.
In fiscal 2021, we did not repurchase any shares but in fiscal 2020 and 2019 we repurchased $34.6 million and $56.4 million of our common stock under existing authorizations, respectively. In fiscal 2021, 2020 and 2019, we reissued 13,465, 17,410 and 3,256 shares out of our treasury stock, respectively, to participants under the Company's Employee Stock Purchase Plan.
In fiscal 2019, we reissued 1,177,630 shares from our treasury stock to satisfy $100.0 million of the initial purchase consideration of $750.0 million, in connection with the Alpha acquisition.
A substantial majority of the Company’s cash and investments are held by foreign subsidiaries. The majority of that cash and investments is expected to be utilized to fund local operating activities, capital expenditure requirements and acquisitions. The Company believes that it has sufficient sources of domestic and foreign liquidity.
We believe that our strong capital structure and liquidity affords us access to capital for future capital expenditures, acquisition and stock repurchase opportunities and continued dividend payments.
Critical Accounting Policies and Estimates
Our significant accounting policies are described in Note 1 - Summary of Significant Accounting Policies to the Consolidated Financial Statements in Item 8. In preparing our financial statements, management is required to make estimates and assumptions that, among other things, affect the reported amounts in the Consolidated Financial Statements and accompanying notes. These estimates and assumptions are most significant where they involve levels of subjectivity and judgment necessary to account for highly uncertain matters or matters susceptible to change, and where they can have a material impact on our financial condition and operating performance. We discuss below the more significant estimates and related assumptions used in the preparation of our Consolidated Financial Statements. If actual results were to differ materially from the estimates made, the reported results could be materially affected.
Revenue Recognition
We adopted the accounting standard for the recognition of revenue under ASC 606 for the fiscal year beginning on April 1, 2019. Under this standard, we recognize revenue only when we have satisfied a performance obligation through transferring control of the promised good or service to a customer. The standard indicates that an entity must determine at contract inception whether it will transfer control of a promised good or service over time or satisfy the performance obligation at a point in time through analysis of the following criteria: (i) the entity has a present right to payment, (ii) the customer has legal title, (iii) the
32

Table of Contents
customer has physical possession, (iv) the customer has the significant risks and rewards of ownership and (v) the customer has accepted the asset. Our primary performance obligation to our customers is the delivery of finished goods and products, pursuant to purchase orders. Control of the products sold typically transfers to our customers at the point in time when the goods are shipped as this is also when title generally passes to our customers under the terms and conditions of our customer arrangements.
We assess collectibility based primarily on the customer’s payment history and on the creditworthiness of the customer.
Management believes that the accounting estimates related to revenue recognition are critical accounting estimates because they require reasonable assurance of collection of revenue proceeds and completion of all performance obligations. Also, revenues are recorded net of provisions for sales discounts and returns, which are established at the time of sale. These estimates are based on our past experience. For additional information on the new accounting standard for the recognition of revenue see Note 1 of Notes to the Consolidated Financial Statements.
Asset Impairment Determinations
We test for the impairment of our goodwill and indefinite-lived trademarks at least annually and whenever events or circumstances occur indicating that a possible impairment has been incurred.
We assess whether goodwill impairment exists using both qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If, based on this qualitative assessment, we determine it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, or if we elect not to perform a qualitative assessment, a quantitative assessment is performed to determine whether a goodwill impairment exists at the reporting unit.
We perform our annual goodwill impairment test on the first day of our fourth quarter for each of our reporting units based on the income approach, also known as the discounted cash flow (“DCF”) method, which utilizes the present value of future cash flows to estimate fair value. We also use the market approach, which utilizes market price data of companies engaged in the same or a similar line of business as that of our company, to estimate fair value. A reconciliation of the two methods is performed to assess the reasonableness of fair value of each of the reporting units.
The future cash flows used under the DCF method are derived from estimates of future revenues, operating income, working capital requirements and capital expenditures, which in turn reflect our expectations of specific global, industry and market conditions. The discount rate developed for each of the reporting units is based on data and factors relevant to the economies in which the business operates and other risks associated with those cash flows, including the potential variability in the amount and timing of the cash flows. A terminal growth rate is applied to the final year of the projected period and reflects our estimate of stable growth to perpetuity. We then calculate the present value of the respective cash flows for each reporting unit to arrive at the fair value using the income approach and then determine the appropriate weighting between the fair value estimated using the income approach and the fair value estimated using the market approach. Finally, we compare the estimated fair value of each reporting unit to its respective carrying value in order to determine if the goodwill assigned to each reporting unit is potentially impaired. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value, an impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit.
Significant assumptions used include management’s estimates of future growth rates, the amount and timing of future operating cash flows, capital expenditures, discount rates, as well as market and industry conditions and relevant comparable company multiples for the market approach. Assumptions utilized are highly judgmental, especially given the role technology plays in driving the demand for products in the telecommunications and aerospace markets.
Based on the results of the annual impairment test as of January 4, 2021, we determined there were no indicators of goodwill impairment.
The indefinite-lived trademarks are tested for impairment by comparing the carrying value to the fair value based on current revenue projections of the related operations, under the relief from royalty method. Any excess carrying value over the amount of fair value is recognized as impairment. Any impairment would be recognized in full in the reporting period in which it has been identified.
33

Table of Contents
With respect to our other long-lived assets other than goodwill and indefinite-lived trademarks, we test for impairment when indicators of impairment are present. An asset is considered impaired when the undiscounted estimated net cash flows expected to be generated by the asset are less than its carrying amount. The impairment recognized is the amount by which the carrying amount exceeds the fair value of the impaired asset.
Business Combinations
We account for business combinations in accordance with ASC 805, Business Combinations. We recognize assets acquired and liabilities assumed in acquisitions at their fair values as of the acquisition date, with the acquisition-related transaction and
restructuring costs expensed in the period incurred. Determining the fair value of assets acquired and liabilities assumed often involves estimates based on third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses and may include estimates of attrition, inflation, asset growth rates, discount rates, multiples of earnings or other relevant factors. In addition, fair values are subject to refinement for up to a year after the closing date of an acquisition. Adjustments recorded to the acquired assets and liabilities are applied prospectively.
Fair values are based on estimates using management's assumptions using future growth rates, future attrition of the customer base, discount rates, multiples of earnings or other relevant factors.
Any change in the acquisition date fair value of assets acquired and liabilities assumed may materially affect our financial position, results of operations and liquidity.
Litigation and Claims
From time to time, the Company has been or may be a party to various legal actions and investigations including, among others, employment matters, compliance with government regulations, federal and state employment laws, including wage and hour laws, contractual disputes and other matters, including matters arising in the ordinary course of business. These claims may be brought by, among others, governments, customers, suppliers and employees. Management considers the measurement of litigation reserves as a critical accounting estimate because of the significant uncertainty in some cases relating to the outcome of potential claims or litigation and the difficulty of predicting the likelihood and range of potential liability involved, coupled with the material impact on our results of operations that could result from litigation or other claims.
In determining legal reserves, management considers, among other inputs:
•interpretation of contractual rights and obligations;
•the status of government regulatory initiatives, interpretations and investigations;
•the status of settlement negotiations;
•prior experience with similar types of claims;
•whether there is available insurance coverage; and
•advice of outside counsel.
For certain matters, management is able to estimate a range of losses. When a loss is probable, but no amount of loss within a range of outcomes is more likely than any other outcome, management will record a liability based on the low end of the estimated range. Additionally, management will evaluate whether losses in excess of amounts accrued are reasonably possible, and will make disclosure of those matters based on an assessment of the materiality of those addition possible losses.
Environmental Loss Contingencies
Accruals for environmental loss contingencies (i.e., environmental reserves) are recorded when it is probable that a liability has been incurred and the amount can reasonably be estimated. Management views the measurement of environmental reserves as a critical accounting estimate because of the considerable uncertainty surrounding estimation, including the need to forecast well into the future. From time to time, we may be involved in legal proceedings under federal, state and local, as well as international environmental laws in connection with our operations and companies that we have acquired. The estimation of environmental reserves is based on the evaluation of currently available information, prior experience in the remediation of contaminated sites and assumptions with respect to government regulations and enforcement activity, changes in remediation technology and practices, and financial obligations and creditworthiness of other responsible parties and insurers.
34

Table of Contents
Warranty
We record a warranty reserve for possible claims against our product warranties, which generally run for a period ranging from one to twenty years for our Energy Systems batteries, one to seven years for our Motive Power batteries and for a period ranging from one to four for Specialty transportation batteries. The assessment of the adequacy of the reserve includes a review of open claims and historical experience.
Management believes that the accounting estimate related to the warranty reserve is a critical accounting estimate because the underlying assumptions used for the reserve can change from time to time and warranty claims could potentially have a material impact on our results of operations.
Allowance for Doubtful Accounts
Subsequent to the adoption of ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326)” effective April 1, 2020 the Company uses an expected loss model as mandated by the standard. The expected loss model: (i) estimates the risk of loss even when risk is remote, (ii) estimates losses over the contractual life, (iii) considers past events, current conditions and reasonable supported forecasts and (iv) has no recognition threshold.
The Company estimates the allowance for credit losses in relation to accounts receivable based on relevant qualitative and quantitative information about historical events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported accounts receivable. Subsequent to April 1, 2020, accounts receivable are recorded at amortized cost less an allowance for expected credit losses. The Company maintains an allowance for credit losses for the expected failure or inability of its customers to make required payments. The Company recognizes the allowance for expected credit losses at inception and reassesses quarterly, based on management’s expectation of the asset’s collectability. The allowance is based on multiple factors including historical experience with bad debts, the credit quality of the customer base, the aging of such receivables and current macroeconomic conditions, as well as management’s expectations of conditions in the future. The Company’s allowance for uncollectible accounts receivable is based on management’s assessment of the collectability of assets pooled together with similar risk characteristics. The Company then adjusts the historical credit loss percentage by current and forecasted economic conditions. The Company then includes a baseline credit loss percentage into the historical credit loss percentage for each aging category to reflect the potential impact of the current and economic conditions. Such a baseline calculation will be adjusted further if changes in the economic environment impacts the Company's expectation for future credit losses.
Management believes that the accounting estimate related to the allowance for doubtful accounts is a critical accounting estimate because the underlying assumptions used for the allowance can change from time to time and uncollectible accounts could potentially have a material impact on our results of operations.
Retirement Plans
We use certain economic and demographic assumptions in the calculation of the actuarial valuation of liabilities associated with our defined benefit plans. These assumptions include the discount rate, expected long-term rates of return on assets and rates of increase in compensation levels. Changes in these assumptions can result in changes to the pension expense and recorded liabilities. Management reviews these assumptions at least annually. We use independent actuaries to assist us in formulating assumptions and making estimates. These assumptions are updated periodically to reflect the actual experience and expectations on a plan-specific basis, as appropriate.
For benefit plans which are funded, we establish strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent balance between return and risk. We set the expected long-term rate of return based on the expected long-term average rates of return to be achieved by the underlying investment portfolios. In establishing this rate, we consider historical and expected returns for the asset classes in which the plans are invested, advice from pension consultants and investment advisors, and current economic and capital market conditions. The expected return on plan assets is incorporated into the computation of pension expense. The difference between this expected return and the actual return on plan assets is deferred and will affect future net periodic pension costs through subsequent amortization.
We believe that the current assumptions used to estimate plan obligations and annual expense are appropriate in the current economic environment. However, if economic conditions change materially, we may change our assumptions, and the resulting change could have a material impact on the Consolidated Statements of Income and on the Consolidated Balance Sheets.

Equity-Based Compensation
We recognize compensation cost relating to equity-based payment transactions by using a fair-value measurement method whereby all equity-based payments to employees, including grants of restricted stock units, stock options, market and performance condition-based awards are recognized as compensation expense based on fair value at grant date over the requisite service period of the awards. We determine the fair value of restricted stock units based on the quoted market price of our common stock on the date of grant. The fair value of stock options is determined using the Black-Scholes option-pricing model, which uses both historical and current market data to estimate the fair value. The fair value of market condition-based awards is estimated at the date of grant using a Monte Carlo Simulation. The fair value of performance condition-based awards is based on the closing stock price on the date of grant, adjusted for a discount to reflect the illiquidity inherent in these awards.
All models incorporate various assumptions such as the risk-free interest rate, expected volatility, expected dividend yield and expected life of the awards. When estimating the requisite service period of the awards, we consider many related factors including types of awards, employee class, and historical experience. Actual results, and future changes in estimates of the requisite service period may differ substantially from our current estimates.
Income Taxes
Our effective tax rate is based on pretax income and statutory tax rates available in the various jurisdictions in which we operate. We account for income taxes in accordance with applicable guidance on accounting for income taxes, which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between book and tax bases on recorded assets and liabilities. Accounting guidance also requires that deferred tax assets be reduced by a valuation allowance, when it is more likely than not that a tax benefit will not be realized.
The recognition and measurement of a tax position is based on management’s best judgment given the facts, circumstances and information available at the reporting date. We evaluate tax positions to determine whether the benefits of tax positions are more likely than not of being sustained upon audit based on the technical merits of the tax position. For tax positions that are more likely than not of being sustained upon audit, we recognize the largest amount of the benefit that is greater than 50% likely of being realized upon ultimate settlement in the financial statements. For tax positions that are not more likely than not of being sustained upon audit, we do not recognize any portion of the benefit in the financial statements. If the more likely than not threshold is not met in the period for which a tax position is taken, we may subsequently recognize the benefit of that tax position if the tax matter is effectively settled, the statute of limitations expires, or if the more likely than not threshold is met in a subsequent period.
We evaluate, on a quarterly basis, our ability to realize deferred tax assets by assessing our valuation allowance and by adjusting the amount of such allowance, if necessary. The factors used to assess the likelihood of realization are our forecast of future taxable income and available tax planning strategies that could be implemented to realize the net deferred tax assets.
To the extent we prevail in matters for which reserves have been established, or are required to pay amounts in excess of our reserves, our effective tax rate in a given financial statement period could be materially affected.

Overview
Our sales in fiscal 2021 were $3.0 billion, a 4% decrease from prior year's sales. This decline was the result of a 5% decrease in organic volume resulting from the pandemic and a 1% decrease in pricing, partially offset by a 2% increase from the NorthStar acquisition.
A discussion of specific fiscal 2021 versus fiscal 2020 operating results follows, including an analysis and discussion of the results of our reportable segments.

Table of Contents
Net sales of our Energy Systems segment in fiscal 2021 increased $22.9 million, or 1.7%, compared to fiscal 2020. This increase was primarily due to a 2% increase from the NorthStar acquisition and a 1% increase in foreign currency translation impact partially offset by a 1% decrease in pricing. Continued strong demand in telecommunication and data center products has offset softness in demand for power supplies from broadband customers.
Net sales of our Motive Power segment in fiscal 2021 decreased by $184.4 million, or 13.7%, compared to fiscal 2020. This decrease was primarily due to a 14% decrease in organic volume and a 1% decrease in pricing, partially offset by a 1% increase in foreign currency translation impact. COVID-19 restrictions and related economic slowdown impacted this segment more than our other lines of business.
Net sales of our Specialty segment in fiscal 2021 increased by $51.6 million, or 13.5%, compared to fiscal 2020. The increase was primarily due to an 8% increase in organic volume, a 6% increase from the NorthStar acquisition and a 1% increase in foreign currency translation impact, partially offset by a 1% decrease in pricing. Demand from customers in the transportation, starting, lighting and ignition market continues to drive significant improvement in revenues in this segment.

Gross profit decreased $45.8 million or 5.8% in fiscal 2021 compared to fiscal 2020. Gross profit, as a percentage of net sales, decreased 60 basis points in fiscal 2021 compared to fiscal 2020. The decrease in the gross profit margin in fiscal 2021 compared to the prior year reflects the impact of unfavorable manufacturing variances resulting from inefficiencies caused by pandemic related lower volumes and transition inefficiencies in the NorthStar facilities as they commission the High Speed Lines (“HSL”) and EnerSys products, partially offset by lower commodity costs net of pricing and the receipt of $7.5 million of insurance proceeds relating to the Richmond fire business interruption claim.

Operating Expenses
Operating expenses decreased $47.4 million or 8.9% in fiscal 2021 from fiscal 2020 and decreased as a percentage of net sales by 90 basis points. Decisive reductions in headcount and discretionary spending made early in our fiscal year along with targeted restructuring and automation efforts, allowed us to substantially reduce our operating expenses, particularly selling expenses, as noted below.
Selling expenses, our main component of operating expenses, were 42.4% of total operating expenses in fiscal 2021, compared to 44.7% of total operating expenses in fiscal 2020.

Restructuring, exit and other charges
Fiscal 2021
During the third quarter of fiscal 2021, we committed to a plan to substantially close our facility in Hagen, Germany, which produces flooded motive power batteries for forklifts. Management determined that future demand for the motive power batteries produced at this facility was not sufficient, given the conversion from flooded to maintenance free batteries by customers, the existing number of competitors in the market, as well as the near term decline in demand and increased uncertainty from the pandemic. We plan to retain the facility with limited sales, service and administrative functions along with related personnel for the foreseeable future.
We currently estimate that the total charges for these actions will amount to approximately $60.0 million, the majority of which are expected to be recorded by the end of calendar 2021. Cash charges of approximately $40.0 million are primarily for employee severance related payments, but also include payments for cleanup related to the facility, contractual releases and legal expenses. Non-cash charges from inventory and equipment write-offs are estimated to be $20.0 million. These actions will result in the reduction of approximately 200 employees. During fiscal 2021, the Company recorded charges relating to severance of $23.3 million and $7.9 million primarily relating to fixed asset write-offs.
During fiscal 2021, we also committed to a plan to close our facility in Vijayawada, India to align with the strategic vision for our new line of business structure and footprint and recorded exit charges of $1.5 million primarily relating to asset write-offs.
In addition, included in our fiscal 2021 operating results are restructuring charges of $3.2 million in Energy Systems, primarily relating to our recent acquisitions and $4.0 million in Motive Power primarily relating to improving operational efficiency in Europe.
Fiscal 2020
Included in our fiscal 2020 operating results were restructuring charges of $6.8 million in the Energy Systems, $1.9 million in Motive Power and $2.3 million in Specialty. Restructuring charges in Energy Systems and Specialty primarily related to the NorthStar acquisition.
Also included in our fiscal 2020 operating results were exit charges of $9.8 million, of which $5.1 million related to the closure of our facility in Targovishte, Bulgaria.
In keeping with our strategy of exiting the manufacture of batteries for diesel-electric submarines, during fiscal 2020, we sold certain licenses and assets for $2.0 million and recorded a net gain of $0.9 million, which were reported as other exit charges in Specialty.
During fiscal 2020, we also wrote off $5.5 million of assets at our Kentucky and Tennessee Motive Power plants, as a result of our strategic product mix shift from traditional flooded batteries to maintenance free lead acid and lithium batteries.
Richmond, Kentucky Plant Fire
During fiscal 2021, the Company settled its claims with its insurance carrier relating to the fire that broke out in the battery formation area of the Company's Richmond, Kentucky motive power production facility in fiscal 2020. The total claims for both property and business interruption of $46.1 million were received through March 31, 2021. The final settlement of insurance recoveries and finalization of costs related to the replacement of property, plant and equipment, resulted in a net gain of $4.4 million, which was recorded as a reduction to operating expenses in the Consolidated Statements of Income.
The details of charges and recoveries for fiscal 2021 and fiscal 2020 are as follows:
In fiscal 2020, the Company recorded $17.0 million as receivable, consisting of write-offs for damages caused to its fixed assets and inventories, as well as for cleanup, asset replacement and other ancillary activities directly associated with the fire and received $12.0 million related to its initial claims.
During fiscal 2021, the Company recorded an additional $16.6 million as receivable for cleanup and received $21.6 million from the insurance carrier.

(1)The percentages shown for the segments are computed as a percentage of the applicable segment’s net sales except for impairment of goodwill and indefinite-lived intangibles, which are shown as percentage of total company net sales, as they related to the Company's legacy reporting units as discussed in Results of Operations—Fiscal 2020 Compared to Fiscal 2019.
Operating earnings increased $26.2 million or 13.8% in fiscal 2021, compared to fiscal 2020. Operating earnings, as a percentage of net sales, increased 110 basis points in fiscal 2021, compared to fiscal 2020.
The Energy Systems operating earnings decreased 10 basis points in fiscal 2021 compared to fiscal 2020. Energy Systems had a very strong year in its sales of batteries and enclosures due to strong telecom demand. Weakness in Power Systems, particularly in the broadband or cable modem/television market largely negated those benefits, resulting in slightly lower year over year results. We believe the influence of the “work from home” phenomenon, resulting from the pandemic made broadband customers focus on expanding capacity in suburban areas rather than focusing on adding power to their networks.
The Motive Power operating earnings increased 140 basis points in fiscal 2021 compared to fiscal 2020. Our Motive Power segment was the most impacted by COVID-19 with revenues in the first half of our fiscal year down by 20%, but recovered in the second half. The Richmond, KY facility has fully recovered from the damage caused by the fire discussed earlier and is operating at near historic levels of efficiency. The restructuring of our Hagen facility announced in November 2020, also allowed us to start shedding significant fixed costs, while absorbing Hagen’s output in existing facilities.
Despite Specialty operating earnings decreasing by 50 basis points in fiscal 2021 compared to fiscal 2020, this segment had a strong year, primarily from burgeoning demand from the transportation market. This segment also incurred significant manufacturing inefficiencies from the pandemic in the first half of fiscal 2021 and the startup of the new HSL in our

Springfield, MO facilities in the second half. Specialty did increase its operating earnings dollars by $3.8 million, compared to the prior year.

Interest expense of $38.5 million in fiscal 2021 (net of interest income of $2.3 million) was $5.2 million lower than the $43.7 million in fiscal 2020 (net of interest income of $2.2 million).
Our average debt outstanding was $1,105.5 million in fiscal 2021, compared to our average debt outstanding of $1,097.9 million in fiscal 2020. Our average cash interest rate incurred in fiscal 2021 was 3.3% and was 3.8% in fiscal 2020. The decrease in interest expense in fiscal 2021 compared to fiscal 2020 is primarily due to lower average interest rates.
In fiscal 2020, in connection with the issuance of the 2027 Notes, we capitalized $4.6 million of debt issuance costs. Included in interest expense were non-cash charges related to amortization of deferred financing fees of $2.1 million in fiscal 2021 and $1.7 million in fiscal 2020.

to fiscal 2020 is primarily due to Swiss tax reform, partially offset by the Hagen, Germany exit charges and changes in the mix of earnings among tax jurisdictions.
On May 19, 2019, a public referendum held in Switzerland approved the Federal Act on Tax Reform and AHV (Old-Age and Survivors Insurance) Financing (TRAF) as adopted by the Swiss Federal Parliament on September 28, 2018. The Swiss tax reform measures were effective January 1, 2020. We recorded a net deferred tax asset of $22.5 million during fiscal 2020, related to the amortizable goodwill and based on further evaluation with the Swiss tax authority, recorded an additional income tax benefit of $1.9 million during fiscal 2021.
The fiscal 2021 foreign effective income tax rate was 6.8% on foreign pre-tax income of $114.1 million compared to an effective income tax rate of (7.4%) on foreign pre-tax income of $110.7 million in fiscal 2020. For both fiscal 2021 and 2020, the difference in the foreign effective tax rate versus the U.S. statutory rate of 21% is primarily attributable to lower tax rates in the foreign countries in which we operate. The rate increase in fiscal 2021 compared to fiscal 2020 is primarily due to Swiss tax reform, partially offset by the Hagen, Germany exit charges and changes in the mix of earnings among tax jurisdictions. Income from our Swiss subsidiary comprised a substantial portion of our overall foreign mix of income for both fiscal 2021 and fiscal 2020 and was taxed, excluding the impact from Swiss tax reform, at approximately 8% and 3%, respectively.

Overview
Our sales in fiscal 2020 were $3.1 billion, a 10% increase from prior year's sales. This increase was the result of a 17% increase due to the Alpha and NorthStar acquisitions (as discussed in Part I, Item 1 of this Annual Report), partially offset by a 4% decrease in organic volume, a 2% decrease in foreign currency translation impact and a 1% decrease in pricing. Organic volume decline in fiscal 2020 reflects the impact of the recent fire and ERP execution challenges in our Richmond, Kentucky facility and weakness in the European and Asian markets.

Net sales of our Energy Systems segment increased in fiscal 2020 by $271.0 million, or 25.0%, compared to the prior year, primarily due to a 40% increase from the Alpha and NorthStar acquisitions, partially offset by a 12% decrease in organic volume, a 2% decrease in currency translation impact and a 1% decrease in pricing. The decrease in organic volume in fiscal 2020 is primarily from the deferral of spending by telecom and broadband customers and the conclusion of a large enclosure order in the preceding year.
Net sales of our Motive Power segment decreased in fiscal 2020 by $43.6 million, or 3.1%, compared to the prior year, primarily due to a 2% decrease in currency translation impact and a 1% decrease in pricing. The lack of organic growth in motive power product volume was due to greater competition in European markets and the September 2019 fire in our Richmond, Kentucky facility.
Net sales of our Specialty segment increased in fiscal 2020 by $52.4 million, or 15.9%, compared to the prior year, primarily due to a 9% increase from the NorthStar acquisition and an 8% increase in organic volume, partially offset by a 1% decrease in pricing. Organic volume improvement is primarily due to our continuing push into the transportation markets for starting, lighting and ignition batteries for cars and trucks.

Gross profit increased $91.8 million or 13.3% in fiscal 2020 compared to fiscal 2019. Gross profit, as a percentage of net sales, increased 70 basis points in fiscal 2020 compared to fiscal 2019. This increase in the gross profit margin is largely a function of declines in commodity costs relative to pricing, partially offset by higher manufacturing costs.

Operating Expenses
Operating expenses increased $88.3 million or 20% in fiscal 2020 from fiscal 2019 and increased as a percentage of net sales by 140 basis points. Excluding the impact of the foreign currency translation, the increase reflects the inclusion of Alpha and NorthStar, as well as an increase of $25.0 million towards new product development.
Selling expenses, our main component of operating expenses, were 44.7% of total operating expenses in fiscal 2020, compared to 46.4% of total operating expenses in fiscal 2019.
Impairment of goodwill and indefinite-lived intangibles
Goodwill is tested annually for impairment during the fourth quarter or earlier upon the occurrence of certain events or substantive changes in circumstances that indicate goodwill is more likely than not impaired.
In the fourth quarter of fiscal 2020, we conducted our annual goodwill impairment test which indicated that the fair value of Asia was less than its carrying value. We recorded a non-cash charge of $39.7 million related to goodwill impairment in our legacy Asia reporting unit under the caption “Impairment of goodwill” in the Consolidated Statements of Income. We also recorded a non-cash charge of $4.5 million related to indefinite-lived trademarks in our legacy EMEA segment, under the caption “Impairment of indefinite-lived intangibles” in the Consolidated Statements of Income. The key factors contributing to the impairment in Asia was the increasing pressure on organic sales growth that we began to experience in fiscal 2019 due to a slowdown in telecom spending in the PRC amidst growing trade tensions between the U.S.A and China. The impact of these trade tensions on our ability to capture market share in the PRC accelerated in the second half of the fiscal year. Throughout fiscal 2020, there was a general slowdown in the Chinese economy which was further exacerbated by the outbreak of the COVID-19 pandemic, causing disruption to two of our plants in China in the fourth quarter. Also contributing to the poor performance of the Asia region was a general softening of demand in Australia, that began in fiscal 2019 and continued throughout fiscal 2020. We monitored the performance of our Asia reporting unit for interim impairment indicators throughout fiscal 2020, but the emergence of COVID-19 in China in December 2019 coupled with the totality of economic headwinds in the region resulted in the recognition of a goodwill impairment loss in connection with our annual impairment test.
During the fourth quarter of fiscal 2020, management completed its evaluation of key inputs used to estimate the fair value of its indefinite-lived trademarks and determined that an impairment charge relating to two of its trademarks in the EMEA segment, that were acquired through legacy acquisitions was appropriate, as it plans to phase out these trademarks.
Restructuring, exit and other charges
Fiscal 2020
Included in our fiscal 2020 operating results were restructuring charges of $6.8 million in the Energy Systems, $1.9 million in Motive Power and $2.3 million in Specialty. Restructuring charges in Energy Systems and Specialty primarily related to the NorthStar acquisition.
Also included in our fiscal 2020 operating results were exit charges of $9.8 million, of which $5.1 million related to the closure of our facility in Targovishte, Bulgaria in Specialty.
In keeping with our strategy of exiting the manufacture of batteries for diesel-electric submarines, during fiscal 2020, we sold certain licenses and assets for $2.0 million and recorded a net gain of $0.9 million, which were reported as other exit charges in Specialty.
During fiscal 2020, we also wrote off $5.5 million of assets at our Kentucky and Tennessee Motive Power plants, as a result of our strategic product mix shift from traditional flooded batteries to maintenance free lead acid and lithium batteries.
Fiscal 2019
Included in our fiscal 2019 operating results were restructuring charges of $5.1 million in the Energy Systems, $4.8 million in Motive Power and $0.7 million in Specialty.
Also included in our fiscal 2019 operating results were exit charges of $24.1 million, of which $17.7 million related to the closure of our facility in Targovishte, Bulgaria (Specialty), $4.9 million related to the disposition of GAZ Geräte - und

Akkumulatorenwerk Zwickau GmbH, a wholly-owned German subsidiary (Energy Systems) and $1.0 million related to dissolving a joint venture in Tunisia (Motive).
The facility in Bulgaria produced diesel-electric submarine batteries. Management determined that the future demand for batteries of diesel-electric submarines was not sufficient given the number of competitors in the market. The $17.7 million charges were primarily non-cash charges of $15.0 million related to the write-off of fixed assets and $2.7 million of severance payments. In addition, cost of goods sold also included a $2.5 million of inventory write-off relating to the closure of the Bulgaria facility. These exit activities are a consequence of the Company's strategic decision to streamline its product portfolio and focus its efforts on new technologies.
Richmond, Kentucky Plant Fire
On September 19, 2019, a fire broke out in the battery formation area of our Richmond, Kentucky motive power production facility. We maintain insurance policies for both property damage and business interruption and are finishing cleanup and repair.
We recorded $10.0 million of damages caused to our fixed assets and inventories, as well as for cleanup, asset replacement and other ancillary activities directly associated with the fire, which were initially reflected as a receivable for probable insurance recoveries. We received $12.0 million in advances related to our initial claims for recovery from our property and casualty insurance carriers in fiscal 2020. Subsequent to March 31, 2020, we also received an additional $8.7 million towards the business interruption claim, of which, $5.0 million was booked as a reduction to our cost of goods sold in our fourth quarter. The final settlement of this claim is discussed further under Results of Operations—Fiscal 2021 Compared to Fiscal 2020 in this section.

Operating earnings decreased $22.3 million or 10.5% in fiscal 2020, compared to fiscal 2019. Operating earnings, as a percentage of net sales, decreased 150 basis points in fiscal 2020, compared to fiscal 2019. Excluding the impact of highlighted items, operating earnings in fiscal 2020 decreased 100 basis points primarily due to the September 2019 fire at our Richmond, Kentucky motive power production facility which resulted in missed sales opportunities and higher manufacturing costs, as well as the decline in our organic volume.
The Energy Systems operating earnings, increased $22.7 million, or 50.1%, in fiscal 2020 compared to fiscal 2019, with the operating margin increasing 80 basis points to 5.0%. This positive impact was primarily due to Alpha's contribution to operating earnings of $53.2 million or 9.7% of its sales for fiscal 2020, as well as the impact of lower commodity costs.
The Motive Power operating earnings, decreased $26.0 million, or 15.0%, in fiscal 2020 compared to fiscal 2019, with the operating margin decreasing 150 basis points to 10.9%. The decrease is primarily due to the fire at our Richmond, Kentucky, facility that resulted in missed sales opportunities and higher manufacturing costs.

Table of Contents
The Specialty operating earnings, decreased $1.6 million, or 3.7%, in fiscal 2020 compared to fiscal 2019, with the operating margin decreasing by 230 basis points to 11.1% mainly due to manufacturing inefficiencies at its primary source of product, as that facility attempted to ramp up production.

Interest expense of $43.7 million in fiscal 2020 (net of interest income of $2.2 million) was $12.8 million higher than the $30.9 million in fiscal 2019 (net of interest income of $2.1 million).
Our average debt outstanding was $1,097.9 million in fiscal 2020, compared to our average debt outstanding of $742.0 million in fiscal 2019. Our average cash interest rate incurred in fiscal 2020 was 3.8% and was 4.1% in fiscal 2019. The increase in interest expense was primarily due to higher average debt incurred to fund the Alpha and NorthStar acquisitions.
In connection with the issuance of the 2027 Notes, we capitalized $4.6 million of debt issuance costs. Included in interest expense were non-cash charges related to amortization of deferred financing fees of $1.7 million in fiscal 2020 and $1.3 million in fiscal 2019.

Our effective income tax rate with respect to any period may be volatile based on the mix of income in the tax jurisdictions in which we operate and the amount of our consolidated income before taxes.
On December 22, 2017, the Tax Cuts and Jobs Act (“Tax Act”) was enacted into law. Among the significant changes resulting from the law, the Tax Act reduced the U.S. federal income tax rate from 35% to 21% effective January 1, 2018, and required companies to pay a one-time transition tax on unrepatriated cumulative non-U.S. earnings of foreign subsidiaries and created new taxes on certain foreign sourced earnings. The U.S. federal statutory tax rate for fiscal 2020 and 2019 is 21.0%.
The Company’s income tax provision consists of federal, state and foreign income taxes. The effective income tax rate was 6.7% in fiscal 2020 compared to the fiscal 2019 effective income tax rate of 11.9%. The rate decrease in fiscal 2020 compared to fiscal 2019 is primarily due to changes in mix of earnings among tax jurisdictions, Swiss tax reform, and items related to the Tax Act in fiscal 2019.
On May 19, 2019, a public referendum held in Switzerland approved the Federal Act on Tax Reform and AHV (Old-Age and Survivors Insurance) Financing (TRAF) as adopted by the Swiss Federal Parliament on September 28, 2018. The Swiss tax reform measures are effective January 1, 2020. Certain provisions of the TRAF were enacted during the second quarter of fiscal 2020. Significant changes in the tax reform include the abolishment of preferential tax regimes for holding companies, domicile companies and mixed companies at the cantonal level. The transitional provisions of the TRAF allow companies to elect tax basis adjustments to fair value, which is used for tax depreciation and amortization purposes resulting in a deduction over the transitional period. We recorded a net deferred tax asset of $22.5 million during fiscal 2020, related to the amortizable goodwill.
The fiscal 2020 foreign effective income tax rate was (7.4%) on foreign pre-tax income of $110.7 million compared to effective income tax rate of 12.3% on foreign pre-tax income of $128.9 million in fiscal 2019. For both fiscal 2020 and 2019, the difference in the foreign effective tax rate versus the U.S. statutory rate of 21% is primarily attributable to lower tax rates in the foreign countries in which we operate. The rate decrease in fiscal 2020 compared to fiscal 2019 is primarily due to Swiss tax reform and changes in the mix of earnings among tax jurisdictions. Income from our Swiss subsidiary comprised a substantial portion of our overall foreign mix of income for both fiscal 2020 and fiscal 2019 and was taxed, excluding the impact from Swiss tax reform, at approximately 3% and 4%, respectively.
Liquidity and Capital Resources
Cash Flow and Financing Activities
Cash and cash equivalents at March 31, 2021, 2020 and 2019, were $451.8 million, $327.0 million and $299.2 million, respectively.

Table of Contents
In fiscal 2021, net earnings were $143.3 million, depreciation and amortization $94.1 million, stock-based compensation $19.8 million, non-cash charges relating to exit charges $10.2 million, primarily relating to the Hagen, Germany plant closure, net gain from the disposal of assets of $3.9 million ($4.4 million from the insurance settlement relating to the Richmond fire claim), deferred tax benefit of $9.0 million and non-cash interest of $2.1 million. Decrease in primary working capital of $53.7 million, net of currency translation changes provided a source of funds and are explained below. Prepaid and other current assets provided a source of funds of $27.3 million, primarily from the receipt of $29.1 million towards the insurance receivable relating to the Richmond plant claim in fiscal 2020 and the receipt of a working capital adjustment claim of $2.0 million, relating to an acquisition made several years ago, partially offset by an increase of $3.8 million in other prepaid expenses. Accrued expenses provided a source of funds of $32.4 million primarily from payroll related accruals of $27.8 million, taxes payable of $4.5 million and selling and other expenses of $3.3 million, partially offset by payments relating to warranty of $5.8 million. Other liabilities decreased by $12.7 million primarily relating to income taxes.
During fiscal 2020, cash provided by operating activities was primarily from net earnings of $137.1 million, depreciation and amortization of $87.3 million, non-cash charges relating to impairment of goodwill and other intangible assets of $44.2 million, restructuring, exit and other charges of $11.0 million, stock-based compensation of $20.8 million, provision for bad debts of $4.8 million and non-cash interest of $1.7 million, partially offset by deferred taxes of $16.5 million primarily from the Swiss Tax Reform. Cash provided by earnings adjusted for non-cash items were partially offset by the increase in primary working capital of $16.4 million, net of currency translation changes. Accrued expenses increased by $7.1 million, primarily due to payroll accruals of $8.6 million, sales incentives of $8.0 million, interest of $3.9 million, partially offset by payments of $7.3 million related to the German competition authority matter and $6.1 million paid to the seller in connection with the Alpha acquisition, for certain reimbursable pre-acquisition items. Prepaid and other current assets increased by $17.5 million, primarily due to contract assets of $11.1 million, insurance receivable of $22.0 million relating to the Richmond plant claim, partially offset by insurance proceeds of $12.0 million and the receipt of $4.1 million in connection with the Alpha transaction. Other liabilities decreased by $12.7 million due to income taxes.
During fiscal 2019, cash provided by operating activities was primarily from net earnings of $160.5 million, depreciation and amortization of $63.3 million, non-cash charges relating to write-off of assets of $26.3 million, stock-based compensation of $22.6 million, non-cash interest of $1.3 million and provision for bad debts accounts of $1.4 million, partially offset by deferred tax benefit of $6.5 million. Cash provided by earnings as adjusted for non-cash items was partially offset by the increase in primary working capital of $30.7 million, net of currency translation changes, and a decrease in other long-term liabilities of $14.9 million, primarily related to income taxes. Prepaid and other current assets, primarily comprising of contract assets, also resulted in a decrease of $20.2 million to operating cash.
As explained in the discussion of our use of “non-GAAP financial measures,” we monitor the level and percentage of primary working capital to sales. Primary working capital was $797.9 million (yielding a primary working capital percentage of 24.5%) at March 31, 2021 and $833.5 million (yielding a primary working capital percentage of 26.7%) at March 31, 2020. The primary working capital percentage of 24.5% at March 31, 2021 is 220 basis points lower than that for March 31, 2020, and 170 basis points lower than that for March 31, 2019. The large decrease in primary working capital dollars, compared to the prior year periods is primarily due to improved accounts receivable collections, improved inventory turns and increased accounts payable primarily due to our TPPL plant ramp-up.
Primary Working Capital and Primary Working Capital percentages at March 31, 2021, 2020 and 2019 are computed as follows:

Balance at March 31, (1) (2) |  | Trade Receivables |  | Inventory |  | Accounts Payable |  | Primary Working Capital |  | Quarter Revenue Annualized |  | Primary Working Capital (%)
|  |  |  | (in millions) |  |  |  |

(1) The Company acquired NorthStar on September 30, 2019, as disclosed in Note 4 to the Consolidated Financial Statements. Therefore, the primary working capital and related calculations as of March 31, 2019 did not include NorthStar's primary working capital and its components.
(2) The inclusion of NorthStar from its respective date of acquisition did not have a material impact on the Company's consolidated primary working capital as of March 31, 2020.

Proceeds from stock options were $9.0 million and net borrowings on short-term debt were $37.4 million.
As a result of the above, total cash and cash equivalents increased by $124.8 million from $327.0 million at March 31, 2020 to $451.8 million at March 31, 2021.
In addition to cash flows from operating activities, we had available committed and uncommitted credit lines of approximately $820 million at March 31, 2021 to cover short-term liquidity requirements. Our Amended Credit Facility is committed through September 30, 2022, as long as we continue to comply with the covenants and conditions of the credit facility agreement. We have $698 million in available committed credit lines under our Amended Credit Facility at March 31, 2021.
Compliance with Debt Covenants
All obligations under our Amended Credit Facility are secured by, among other things, substantially all of our U.S. assets. The Amended Credit Facility contains various covenants which, absent prepayment in full of the indebtedness and other obligations, or the receipt of waivers, limit our ability to conduct certain specified business transactions, buy or sell assets out of the ordinary course of business, engage in sale and leaseback transactions, pay dividends and take certain other actions. There are no prepayment penalties on loans under this credit facility.
We are in compliance with all covenants and conditions under our Amended Credit Facility and Senior Notes. We believe that we will continue to comply with these covenants and conditions, and that we have the financial resources and the capital available to fund the foreseeable organic growth in our business and to remain active in pursuing further acquisition opportunities. See Note 10 to the Consolidated Financial Statements included in this Annual Report on Form 10-K.

Due to the uncertainty of future cash outflows, uncertain tax positions have been excluded from the above table.
Under our Amended Credit Facility and other credit arrangements, we had outstanding standby letters of credit of $3.0 million as of March 31, 2021.
Credit Facilities and Leverage
Our focus on working capital management and cash flow from operations is measured by our ability to reduce debt and reduce our leverage ratios.
In the third quarter of fiscal 2020, we issued $300 million in aggregate principal amount of our 4.375% Senior Notes due 2027 (the “2027 Notes”). Proceeds from this offering, net of debt issuance costs were $296.3 million and were utilized to pay down the balance outstanding on the revolver borrowings.
In the second quarter of fiscal 2018, we entered into the 2017 Credit Facility that comprised a $600.0 million senior secured revolving credit facility (“2017 Revolver”) and a $150.0 million senior secured term loan (“2017 Term Loan”) with a maturity date of September 30, 2022. On December 7, 2018, we amended the 2017 Credit Facility (as amended, the “Amended Credit Facility”). The Amended Credit Facility consists of $449.1 million senior secured term loans (the “Amended 2017 Term Loan”), including a CAD 133.1 million ($99.1 million) term loan and a $700.0 million senior secured revolving credit facility (the “Amended 2017 Revolver”). The amendment resulted in an increase of the 2017 Term Loan and the 2017 Revolver by $299.1 million and $100.0 million, respectively.
Shown below are the leverage ratios at March 31, 2021 and 2020, in connection with the Amended Credit Facility.
The total net debt, as defined under the Amended Credit Facility is $615.0 million for fiscal 2021 and is 1.7 times adjusted EBITDA (non-GAAP), compared to total net debt of $905.6 million and 2.3 times adjusted EBITDA (non-GAAP) for fiscal 2020.

The following table provides a reconciliation of net earnings to EBITDA (non-GAAP) and adjusted EBITDA (non-GAAP) for March 31, 2021 and 2020, in connection with the Amended Credit Facility:

|  | Fiscal 2021 |  | Fiscal 2020
|  | (in millions, except ratios)
Net earnings as reported |  | $ | 143.3 |  |  | $ | 137.1 |

EBITDA (non GAAP)(1) |  | $ | 302.7 |  |  | $ | 278.0 |

Adjusted EBITDA (non-GAAP) per credit agreement(1) |  | $ | 359.0 |  |  | $ | 401.6 |
Total net debt(3) |  | $ | 615.0 |  |  | $ | 905.6 |

Consolidated interest coverage ratio(5) |  | 9.8 X |  | 9.1 X
Minimum ratio required |  | 3.0 X |  | 3.0 X

(1)We have included EBITDA (non-GAAP) and adjusted EBITDA (non-GAAP) because our lenders use them as key measures of our performance. EBITDA is defined as earnings before interest expense, income tax expense, depreciation and amortization. EBITDA is not a measure of financial performance under GAAP and should not be considered an alternative to net earnings or any other measure of performance under GAAP or to cash flows from operating, investing or financing activities as an indicator of cash flows or as a measure of liquidity. Our calculation of EBITDA may be different from the calculations used by other companies, and therefore comparability may be limited. Certain financial covenants in our Amended Credit Facility are based on EBITDA, subject to adjustments, which are shown above. Continued availability of credit under our Amended Credit Facility is critical to our ability to meet our business plans. We believe that an understanding of the key terms of our credit agreement is important to an investor’s understanding of our financial condition and liquidity risks. Failure to comply with our financial covenants, unless waived by our lenders, would mean we could not borrow any further amounts under our revolving credit facility and would give our lenders the right to demand immediate repayment of all outstanding revolving credit and term loans. We would be unable to continue our operations at current levels if we lost the liquidity provided under our credit agreements. Depreciation and amortization in this table excludes the amortization of deferred financing fees, which is included in interest expense.
(2)The $56.3 million adjustment to EBITDA in fiscal 2021 primarily related to $19.8 million of non-cash stock compensation, $33.2 million of restructuring and other exit charges, business integration costs of $7.3 million, partially offset by $3.9 million of gain ($4.4 million gain less insurance deductibles) relating to the final settlement of the Richmond, KY fire claim. The $123.6 million adjustment to EBITDA in fiscal 2020 primarily related to impairment of goodwill and other intangible assets of $44.2 million, $20.8 million of non-cash stock compensation, inclusion of $18.5 million of six months of pro forma earnings of NorthStar, $20.8 million of restructuring and other exit charges and $1.9 million of inventory adjustments (fair value step up relating to the NorthStar transaction), $14.3 million for insurance reimbursement for business interruption due to the Richmond, KY fire and other charges of $3.1 million.
(3)Debt includes finance lease obligations and letters of credit and is net of all U.S. cash and cash equivalents and excludes $53 million of foreign cash and investments, as defined in the Amended Credit Facility. In fiscal 2021, the amounts deducted in the calculation of net debt were U.S. cash and cash equivalents and foreign cash investments of $399 million, and in fiscal 2020, were $262 million.
(4)These ratios are included to show compliance with the leverage ratios set forth in our credit facilities. We show both our current ratios and the maximum ratio permitted or minimum ratio required under our Amended Credit Facility, for fiscal 2021 and fiscal 2020, respectively.
(5)As defined in the Amended Credit Facility, interest expense used in the consolidated interest coverage ratio excludes non-cash interest of $2.1 million and $1.7 million for fiscal 2021 and fiscal 2020, respectively.

Sequential Quarterly Information
The first half of fiscal 2021 was negatively impacted by COVID-19 but the Company rebounded in the second half of the year, which also saw the closure of our Hagen facility in Germany. The Company incurred exit charges of $11.7 million in the third quarter and $19.6 million in the fourth quarter, primarily for severance payments, related to this closure. Gross margins remained relatively stable throughout the two years. In the fourth quarter of fiscal 2020, the Company recorded impairment charges relating to goodwill in Asia of $39.7 million and trademarks in EMEA of $4.5 million in the fourth quarter of fiscal 2020. The Company also had an income tax benefit of $21.0 million in the second quarter of fiscal 2020, on account of the Swiss tax reform.
We have also included the operating results of NorthStar, in our third and fourth quarter results, for the period commencing on September 30, 2019 (the date of acquisition). NorthStar's sales for the third and fourth quarters of fiscal 2020 were $27.8 million and $26.7 million, respectively, while net loss, for the same periods were $13.5 million and $0.5 million, respectively. NorthStar sales for the four quarters of fiscal 2021 were $29.9 million, $27.3 million, $17.5 million and $10.3 million, respectively.

ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risks
Our cash flows and earnings are subject to fluctuations resulting from changes in raw material costs, foreign currency exchange rates and interest rates. We manage our exposure to these market risks through internally established policies and procedures and, when deemed appropriate, through the use of derivative financial instruments. Our policy does not allow speculation in derivative instruments for profit or execution of derivative instrument contracts for which there are no underlying exposures. We do not use financial instruments for trading purposes and are not a party to any leveraged derivatives. We monitor our underlying market risk exposures on an ongoing basis and believe that we can modify or adapt our hedging strategies as needed.
Counterparty Risks
We have entered into lead forward purchase contracts and foreign exchange forward and purchased option contracts to manage the risk associated with our exposures to fluctuations resulting from changes in raw material costs and foreign currency exchange rates. The Company’s agreements are with creditworthy financial institutions. Those contracts that result in a liability position at March 31, 2021 are $2.6 million (pre-tax). Those contracts that result in an asset position at March 31, 2021 are $1.0 million (pre-tax) and the vast majority of these will settle within one year. The impact on the Company due to nonperformance by the counterparties has been evaluated and not deemed material.
Interest Rate Risks
We are exposed to changes in variable U.S. interest rates on borrowings under our credit agreements, as well as short term borrowings in our foreign subsidiaries.
A 100 basis point increase in interest rates would have increased annual interest expense by approximately $4.1 million on the variable rate portions of our debt.
Commodity Cost Risks—Lead Contracts
We have a significant risk in our exposure to certain raw materials. Our largest single raw material cost is for lead, for which the cost remains volatile. In order to hedge against increases in our lead cost, we have entered into forward contracts with
55

Table of Contents
financial institutions to fix the price of lead. A vast majority of such contracts are for a period not extending beyond one year. We had the following contracts outstanding at the dates shown below:

Date |  | $’s Under Contract |  | # Pounds Purchased |  | Average Cost/Pound |  | Approximate % of Lead Requirements (1)
|  | (in millions) |  | (in millions) |  |  |  |
March 31, 2021 |  | $50.6 |  | 54.5 |  | $0.93 |  | 10%
March 31, 2020 |  | 30.1 |  | 35.0 |  | 0.86 |  | 6
March 31, 2019 |  | 39.2 |  | 42.0 |  | 0.93 |  | 7

(1)Based on the fiscal year lead requirements for the periods then ended.
We estimate that a 10% increase in our cost of lead would have increased our cost of goods sold by approximately $54 million for the fiscal year ended March 31, 2021.
Foreign Currency Exchange Rate Risks
We manufacture and assemble our products globally in the Americas, EMEA and Asia. Approximately 40% of our sales and related expenses are transacted in foreign currencies. Our sales revenue, production costs, profit margins and competitive position are affected by the strength of the currencies in countries where we manufacture or purchase goods relative to the strength of the currencies in countries where our products are sold. Additionally, as we report our financial statements in U.S. dollars, our financial results are affected by the strength of the currencies in countries where we have operations relative to the strength of the U.S. dollar. The principal foreign currencies in which we conduct business are the Euro, Swiss franc, British pound, Polish zloty, Chinese renminbi, Canadian dollar, Brazilian Real and Mexican peso.
We quantify and monitor our global foreign currency exposures. Our largest foreign currency exposure is from the purchase and conversion of U.S. dollar based lead costs into local currencies in Europe. Additionally, we have currency exposures from intercompany financing and intercompany and third party trade transactions. On a selective basis, we enter into foreign currency forward contracts and purchase option contracts to reduce the impact from the volatility of currency movements; however, we cannot be certain that foreign currency fluctuations will not impact our operations in the future.
We hedge approximately 10% - 15% of the nominal amount of our known foreign exchange transactional exposures. We primarily enter into foreign currency exchange contracts to reduce the earnings and cash flow impact of the variation of non-functional currency denominated receivables and payables. The vast majority of such contracts are for a period not extending beyond one year.
Gains and losses resulting from hedging instruments offset the foreign exchange gains or losses on the underlying assets and liabilities being hedged. The maturities of the forward exchange contracts generally coincide with the settlement dates of the related transactions. Realized and unrealized gains and losses on these contracts are recognized in the same period as gains and losses on the hedged items. We also selectively hedge anticipated transactions that are subject to foreign exchange exposure, primarily with foreign currency exchange contracts, which are designated as cash flow hedges in accordance with Topic 815 - Derivatives and Hedging.
At March 31, 2021 and 2020, we estimate that an unfavorable 10% movement in the exchange rates would have adversely changed our hedge valuations by approximately $3.7 million and $3.0 million, respectively.

To the Stockholders and the Board of Directors of EnerSys
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of EnerSys (the Company) as of March 31, 2021 and 2020, the related consolidated statements of income, comprehensive income, changes in equity, and cash flows for each of the three years in the period ended March 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 March 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended March 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 March 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 May 26, 2021 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 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 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.

|  | Valuation of Indefinite-Lived Intangible Assets
Description of the Matter |  | As reflected in the Company’s consolidated financial statements, the Company’s indefinite-lived intangible assets were $147.2 million as of March 31, 2021 and included $56.0 million of trademarks recognized in connection with the acquisition of the Alpha Group. As discussed in Note 1 to the consolidated financial statements, indefinite-lived intangible assets are tested for impairment at least annually. Auditing management’s annual quantitative indefinite-lived intangible assets impairment tests was complex and involved a high degree of subjectivity due to the significant estimation required in determining the fair value of the indefinite-lived intangible assets. The fair value estimates related to the Company’s indefinite-lived intangible assets were sensitive to significant assumptions such as discount rates, revenue growth rates, royalty rates, and terminal growth rates, which are forward-looking and could be affected by future economic and market conditions.

Table of Contents

How We Addressed the Matter in Our Audit |  | We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s annual quantitative indefinite-lived intangible assets impairment tests. For example, we tested controls over management’s review of the valuation models, the significant assumptions used to develop the estimate including forecasted revenue growth rates and royalty rates, and the completeness and accuracy of the data used in the valuations. To test the estimated fair value of the Company’s indefinite-lived intangible assets, we performed audit procedures that included, among other procedures, assessing fair value methodologies and testing the significant assumptions discussed above and the completeness and accuracy of the underlying data used by the Company in its analyses. For example, we compared the significant assumptions used by management to current industry, market and economic trends, to historical results of the Company's business and other guideline companies within the same industry and to other relevant factors. We assessed the historical accuracy of management’s estimates and performed sensitivity analyses of significant assumptions to evaluate the changes in the fair value of the indefinite-lived intangible assets that would result from changes in the assumptions. We also involved internal valuation specialists to assist in our evaluation of the significant assumptions and methodologies used by the Company.
|  | Income Taxes - Uncertain Tax Positions
Description of the Matter |  | As discussed in Note 14 to the Company’s consolidated financial statements, the Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. Also as disclosed in Note 14, approximately 67% of the Company’s consolidated earnings before taxes are generated in foreign jurisdictions. Uncertainty in a tax position taken or to be taken on a tax return may arise as tax laws are subject to interpretation. The Company must identify its uncertain tax positions and uses significant judgment in (1) determining whether a tax position’s technical merits are more-likely-than-not to be sustained and (2) measuring the amount of tax benefit that qualifies for recognition. As of March 31, 2021, the Company accrued liabilities of $6.8 million for uncertain tax positions. Auditing the completeness of the Company’s uncertain tax positions and the evaluation of the technical merits of those uncertain tax positions is complex given the scope of its international operations and the significant judgment required in evaluating the technical merits of the Company’s uncertain tax positions.
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 identifying uncertain tax positions and evaluating the technical merits of those positions. For example, we tested controls over the review of the Company’s foreign operations, including the tax positions taken by those operations, differences between statutory and effective tax rates, permanent differences impacting taxable income, and the monitoring of tax audits. We involved our tax professionals with subject matter expertise in the areas of international taxation and transfer pricing to assess the technical merits of the Company’s tax positions. This included assessing the Company’s correspondence with the relevant tax authorities and evaluating income tax opinions or other third-party advice obtained by the Company. We also used our knowledge of, and experience with, the application of international and local income tax laws by the relevant income tax authorities to evaluate the Company’s accounting for those tax positions. We analyzed the Company’s assumptions and data used to determine the amount of tax benefit to recognize and tested the accuracy of the calculations. We also evaluated the Company’s income tax disclosures included in Note 14 to the consolidated financial statements in relation to these matters.

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of EnerSys
Opinion on Internal Control over Financial Reporting
We have audited EnerSys’ internal control over financial reporting as of March 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, EnerSys (the Company) maintained, in all material respects, effective internal control over financial reporting as of March 31, 2021, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 2021 consolidated financial statements of the Company and our report dated May 26, 2021 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 Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Consolidated Financial Statements
March 31, 2021
(In Thousands, Except Share and Per Share Data)
1. Summary of Significant Accounting Policies
Description of Business
EnerSys (the “Company”) and its predecessor companies have been manufacturers of industrial batteries for over 125 years. EnerSys is a global leader in stored energy solutions for industrial applications. The Company manufactures, markets and distributes industrial batteries and related products such as chargers, outdoor cabinet enclosures, power equipment and battery accessories, and provides related after-market and customer-support services for its products. With the Alpha acquisition, the Company is also a provider of highly integrated power solutions and services to broadband, telecom, renewable and industrial customers.
Principles of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries and any partially owned subsidiaries that the Company has the ability to control. Control generally equates to ownership percentage, whereby investments that are more than 50% owned are generally consolidated, investments in affiliates of 50% or less but greater than 20% are generally accounted for using the equity method, and investments in affiliates of 20% or less are accounted for using the cost method. All intercompany transactions and balances have been eliminated in consolidation.
Foreign Currency Translation
Results of foreign operations of subsidiaries, whose functional currency is the local currency, are translated into U.S. dollars using average exchange rates during the periods. The assets and liabilities are translated into U.S. dollars using exchange rates as of the balance sheet dates. Gains or losses resulting from translating the foreign currency financial statements are accumulated as a separate component of accumulated other comprehensive income (“AOCI”) in EnerSys’ stockholders’ equity and noncontrolling interests.
Transaction gains and losses resulting from exchange rate changes on transactions denominated in currencies other than the functional currency of the applicable subsidiary are included in the Consolidated Statements of Income, within “Other (income) expense, net”, in the year in which the change occurs.
Revenue Recognition
Beginning April 1, 2018, the Company adopted ASC 606, Revenue from Contracts with Customers. Concurrent with the adoption of the new standard, the Company updated its revenue recognition policy as follows:
The Company determines revenue recognition by applying the following steps:
1. identify the contract with a customer;
2. identify the performance obligations in the contract;
3. determine the transaction price;
4. allocate the transaction price to the performance obligations; and
5. recognize revenue as the performance obligations are satisfied.
The Company recognizes revenue when (or as) performance obligations are satisfied by transferring control of the performance obligation to a customer. Control of a performance obligation may transfer to the customer either at a point in time or over time depending on an evaluation of the specific facts and circumstances for each contract, including the terms and conditions of the contract as agreed with the customer, as well as the nature of the products or services to be provided.
The Company's primary performance obligation to its customers is the delivery of finished goods and products, pursuant to
purchase orders. Control of the products sold typically transfers to its customers at the point in time when the goods are shipped
as this is also when title generally passes to its customers under the terms and conditions of the customer arrangements.
67

Table of Contents
Each customer purchase order sets forth the transaction price for the products and services purchased under that arrangement. Some customer arrangements include variable consideration, such as volume rebates, some of which depend upon the customers meeting specified performance criteria, such as a purchasing level over a period of time. The Company uses judgment to estimate the most likely amount of variable consideration at each reporting date. When estimating variable consideration, the Company also applies judgment when considering the probability of whether a reversal of revenue could occur and only recognize revenue subject to this constraint.
Service revenues related to the work performed for the Company’s customers by its maintenance technicians generally represent a separate and distinct performance obligation. Control for these services passes to the customer as the services are performed.
The Company's typical payment terms are 30 days and sales arrangements do not contain any significant financing component for its customers.
The Company uses historic customer product return data as a basis of estimation for customer returns and records the reduction of sales at the time revenue is recognized.
Freight charges billed to customers are included in sales and the related shipping costs are included in cost of sales in the Consolidated Statements of Income. If shipping activities are performed after a customer obtains control of a product, the Company applies a policy election to account for shipping as an activity to fulfill the promise to transfer the product to the customer.
The Company applies a policy election to exclude transaction taxes collected from customers from sales when the tax is both imposed on and concurrent with a specific revenue-producing transaction.
The Company generally provides customers with a product warranty that provides assurance that the products meet standard specifications and are free of defects. The Company maintains a reserve for claims incurred under standard product warranty programs. Performance obligations related to service warranties are not material to the Consolidated Financial Statements.
The Company pays sales commissions to its sales representatives, which may be considered as incremental costs to obtain a contract. However, since the recoverability period is less than one year, the Company has utilized the practical expedient to record these costs of obtaining a contract as an expense as they are incurred.
Warranties
The Company’s products are warranted for a period ranging from one to twenty years for Energy Systems batteries, from one to seven years for Motive Power batteries and for a period ranging from one to four years for Specialty transportation batteries. The Company provides for estimated product warranty expenses when the related products are sold. The assessment of the adequacy of the reserve includes a review of open claims and historical experience.
Cash and Cash Equivalents
Cash and cash equivalents include all highly liquid investments with an original maturity of three months or less when purchased.
Concentration of Credit Risk
Financial instruments that subject the Company to potential concentration of credit risk consist principally of short-term cash investments and trade accounts receivable. The Company invests its cash with various financial institutions and in various investment instruments limiting the amount of credit exposure to any one financial institution or entity. The Company has bank deposits that exceed federally insured limits. In addition, certain cash investments may be made in U.S. and foreign government bonds, or other highly rated investments guaranteed by the U.S. or foreign governments. Concentration of credit risk with respect to trade receivables is limited by a large, diversified customer base and its geographic dispersion. The Company performs ongoing credit evaluations of its customers’ financial condition and requires collateral, such as letters of credit, in certain circumstances.
68

Table of Contents
Accounts Receivable
Accounts receivable are recorded net of an allowance for expected credit losses. The Company maintains an allowance for credit losses for the expected failure or inability of its customers to make required payments. The Company recognizes the allowance for expected credit losses at inception and reassesses quarterly based on management’s expectation of the asset’s collectability. The allowance is based on multiple factors including historical experience with bad debts, the credit quality of the customer base, the aging of such receivables and current macroeconomic conditions, as well as management’s expectations of conditions in the future. The Company’s allowance for uncollectible accounts receivable is based on management’s assessment of the collectability of assets pooled together with similar risk characteristics. Accounts are written off when management determines the account is uncollectible.
Inventories
Inventories are stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out (FIFO) method. The cost of inventory consists of material, labor, and associated overhead.
Property, Plant, and Equipment
Property, plant, and equipment are recorded at cost and include expenditures that substantially increase the useful lives of the assets. Depreciation is provided using the straight-line method over the estimated useful lives of the assets as follows: 10 to 33 years for buildings and improvements and 3 to 15 years for machinery and equipment.
Maintenance and repairs are expensed as incurred. Interest on capital projects is capitalized during the construction period.
Business Combinations
The Company records an acquisition using the acquisition method of accounting and recognizes the assets acquired and liabilities assumed at their fair values as of the date of the acquisition. The excess of the purchase price over the net tangible and intangible assets is recorded to goodwill. The results of operations of the acquired business are included in the Company’s operating results from the date of acquisition.
Goodwill and Other Intangible Assets
Goodwill and indefinite-lived trademarks are tested for impairment at least annually and whenever events or circumstances occur indicating that a possible impairment may have been incurred. The Company assesses whether goodwill impairment exists using both the qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If based on this qualitative assessment the Company determines it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if the Company elects not to perform a qualitative assessment, a quantitative assessment is performed by determining the fair value of the Company's reporting units.
Goodwill is tested for impairment by determining the fair value of the Company’s reporting units. These estimated fair values are based on financial projections, certain cash flow measures, and market capitalization.
The Company estimates the fair value of its reporting units using a weighting of fair values derived from both the income approach and the market approach. Under the income approach, the Company calculates the fair value of a reporting unit based on the present value of estimated future cash flows. Cash flow projections are based on management's estimates of revenue growth rates and operating margins, taking into consideration industry and market conditions. The discount rate used is based on the weighted-average cost of capital adjusted for the relevant risk associated with business-specific characteristics and the uncertainty related to the business's ability to execute on the projected cash flows. The market approach estimates fair value based on market multiples of revenue and earnings derived from comparable publicly-traded companies with similar operating and investment characteristics as the reporting unit. The weighting of the fair value derived from the market approach ranges from 0% to 50% depending on the level of comparability of these publicly-traded companies to the reporting unit.
In order to assess the reasonableness of the calculated fair values of its reporting units, the Company also compares the sum of the reporting units' fair values to its market capitalization and calculates an implied control premium (the excess of the sum of the reporting units' fair values over the market capitalization). The Company evaluates the control premium by comparing it to control premiums of recent comparable market transactions.

Table of Contents
The Company assesses whether indefinite-lived intangible assets impairment exists using both the qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount. If based on this qualitative assessment, the Company determines it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount or if the Company elects not to perform a qualitative assessment, a quantitative assessment is performed to determine whether an indefinite-lived intangible asset impairment exists. The Company tests the indefinite-lived intangible assets for impairment by comparing the carrying value to the fair value based on current revenue projections of the related operations, under the relief from royalty method. Any excess of the carrying value over the amount of fair value is recognized as an impairment. Any such impairment is recognized in the reporting period in which it has been identified.
Finite-lived assets such as customer relationships, technology, trademarks, licenses, and non-compete agreements are amortized on a straight-line basis over their estimated useful lives, generally over periods ranging from 3 to 20 years. The Company continually evaluates the reasonableness of the useful lives of these assets.
Impairment of Long-Lived Assets
The Company reviews the carrying values of its long-lived assets to be held and used for possible impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable, based on undiscounted estimated cash flows expected to result from its use and eventual disposition. The factors considered by the Company in performing this assessment include current operating results, trends and other economic factors. In assessing the recoverability of the carrying value of a long-lived asset, the Company must make assumptions regarding future cash flows and other factors. If these estimates or the related assumptions change in the future, the Company may be required to record an impairment loss for these assets.
Environmental Expenditures
The Company records a loss and establishes a reserve for environmental remediation liabilities when it is probable that an asset has been impaired or a liability exists and the amount of the liability can be reasonably estimated. Reasonable estimates involve judgments made by management after considering a broad range of information including notifications, demands or settlements that have been received from a regulatory authority or private party, estimates performed by independent engineering companies and outside counsel, available facts, existing and proposed technology, the identification of other potentially responsible parties, their ability to contribute and prior experience. These judgments are reviewed quarterly as more information is received and the amounts reserved are updated as necessary. However, the reserves may materially differ from ultimate actual liabilities if the loss contingency is difficult to estimate or if management’s judgments turn out to be inaccurate. If management believes no best estimate exists, the minimum probable loss is accrued.
Derivative Financial Instruments
The Company utilizes derivative instruments to mitigate volatility related to interest rates, lead prices and foreign currency exposures. The Company does not hold or issue derivative financial instruments for trading or speculative purposes. The Company recognizes derivatives as either assets or liabilities in the accompanying Consolidated Balance Sheets and measures those instruments at fair value. Changes in the fair value of those instruments are reported in AOCI if they qualify for hedge accounting or in earnings if they do not qualify for hedge accounting. Derivatives qualify for hedge accounting if they are designated as hedge instruments and if the hedge is highly effective in achieving offsetting changes in the fair value or cash flows of the asset or liability hedged. Effectiveness is measured on a regular basis using statistical analysis and by comparing the overall changes in the expected cash flows on the lead and foreign currency forward contracts with the changes in the expected all-in cash outflow required for the lead and foreign currency purchases. This analysis is performed on the initial purchases quarterly that cover the quantities hedged. Accordingly, gains and losses from changes in derivative fair value of effective hedges are deferred and reported in AOCI until the underlying transaction affects earnings.
The Company has commodity, foreign exchange and interest rate hedging authorization from the Board of Directors and has established a hedging and risk management program that includes the management of market and counterparty risk. Key risk control activities designed to ensure compliance with the risk management program include, but are not limited to, credit review and approval, validation of transactions and market prices, verification of risk and transaction limits, portfolio stress tests, sensitivity analyses and frequent portfolio reporting, including open positions, determinations of fair value and other risk management metrics.

Table of Contents
Market risk is the potential loss the Company and its subsidiaries may incur as a result of price changes associated with a particular financial or commodity instrument. The Company utilizes forward contracts, options, and swaps as part of its risk management strategies, to minimize unanticipated fluctuations in earnings caused by changes in commodity prices, interest rates and / or foreign currency exchange rates. All derivatives are recognized on the balance sheet at their fair value, unless they qualify for the Normal Purchase Normal Sale exemption.
Credit risk is the potential loss the Company may incur due to the counterparty’s non-performance. The Company is exposed to credit risk from interest rate, foreign currency and commodity derivatives with financial institutions. The Company has credit policies to manage their credit risk, including the use of an established credit approval process, monitoring of the counterparty positions and the use of master netting agreements.
The Company has elected to offset net derivative positions under master netting arrangements. The Company does not have any positions involving cash collateral (payables or receivables) under a master netting arrangement as of March 31, 2021 and 2020.
The Company does not have any credit-related contingent features associated with its derivative instruments.
Fair Value of Financial Instruments
The Company groups its recurring, non-recurring and disclosure-only fair value measurements into the following levels when making fair value measurement disclosures:

Level 1 |  | Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2 |  | Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.
Level 3 |  | Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). The Company and its subsidiaries use, as appropriate, a market approach (generally, data from market transactions), an income approach (generally, present value techniques and option-pricing models), and / or a cost approach (generally, replacement cost) to measure the fair value of an asset or liability. These valuation approaches incorporate inputs such as observable, independent market data and / or unobservable data that management believes are predicated on the assumptions market participants would use to price an asset or liability. These inputs may incorporate, as applicable, certain risks such as nonperformance risk, which includes credit risk.
Lead contracts, foreign currency contracts and interest rate contracts generally use an income approach to measure the fair value of these contracts, utilizing readily observable inputs, such as forward interest rates (e.g., London Interbank Offered Rate—“LIBOR”), forward foreign currency exchange rates (e.g., GBP and euro) and commodity prices (e.g., London Metals Exchange), as well as inputs that may not be observable, such as credit valuation adjustments. When observable inputs are used to measure all or most of the value of a contract, the contract is classified as Level 2. Over-the-counter (OTC) contracts are valued using quotes obtained from an exchange, binding and non-binding broker quotes. Furthermore, the Company obtains independent quotes from the market to validate the forward price curves. OTC contracts include forwards, swaps and options. To the extent possible, fair value measurements utilize various inputs that include quoted prices for similar contracts or market-corroborated inputs.
When unobservable inputs are significant to the fair value measurement, the asset or liability is classified as Level 3. Additionally, Level 2 fair value measurements include adjustments for credit risk based on the Company’s own creditworthiness (for net liabilities) and its counterparties’ creditworthiness (for net assets). The Company assumes that observable market prices include sufficient adjustments for liquidity and modeling risks. The Company did not have any fair value measurements that transferred between Level 2 and Level 3 as well as Level 1 and Level 2.
Income Taxes
The Company accounts for income taxes using the asset and liability approach, which requires deferred tax assets and liabilities be recognized using enacted tax rates to measure the effect of temporary differences between book and tax bases on recorded
71

Table of Contents
assets and liabilities. Valuation allowances are recorded to reduce deferred tax assets, if it is more likely than not some portion or all of the deferred tax assets will not be realized. The need to establish valuation allowances against deferred tax assets is assessed quarterly. The primary factors used to assess the likelihood of realization are expected reversals of taxable temporary timing differences, forecasts of future taxable income and available tax planning strategies that could be implemented to realize the net deferred tax assets.
The Company recognizes tax related interest and penalties in income tax expense in its Consolidated Statement of Income.
With respect to accounting for uncertainty in income taxes, the Company evaluates tax positions to determine whether the benefits of tax positions are more likely than not of being sustained upon audit based on the technical merits of the tax position. For tax positions that are more likely than not of being sustained upon audit, the Company recognizes the largest amount of the benefit that is greater than 50% likely of being realized upon ultimate settlement. For tax positions that are not more likely than not of being sustained upon audit, the Company does not recognize any portion of the benefit. If the more likely than not threshold is not met in the period for which a tax position is taken, the Company may subsequently recognize the benefit of that tax position if the tax matter is effectively settled, the statute of limitations expires, or if the more likely than not threshold is met in a subsequent period.
No additional income taxes have been provided for any undistributed foreign earnings or any additional outside basis difference inherent in these entities, as these amounts continue to be indefinitely reinvested in foreign operations.
Regarding the GILTI tax rules, the Company is allowed to make an accounting policy choice of either (1) treating the taxes due on future US inclusions in taxable income as a current-period expense when incurred (“period cost method”) or (2) factoring amounts into a Company’s measurement of its deferred taxes (“deferred method”). The Company has elected the period cost method.
Deferred Financing Fees
Debt issuance costs that are incurred by the Company in connection with the issuance of debt are deferred and amortized to interest expense over the life of the underlying indebtedness, adjusted to reflect any early repayments and are shown as a deduction from long-term debt.
Stock-Based Compensation Plans
The Company measures the cost of employee services received in exchange for the award of an equity instrument based on the grant-date fair value of the award, with such cost recognized over the applicable vesting period.
Market and Performance condition-based awards
The Company grants market condition-based awards and performance condition-based awards.
Beginning in fiscal 2017 and until fiscal 2020, the Company granted market condition-based awards (“TSR”). A participant may earn between 0% to 200% of the number of awards granted, based on the total shareholder return of the Company's common stock over a three-year period, relative to the shareholder return of a defined peer group. The awards cliff vest on the third anniversary of the date of grant and are settled in common stock on the first anniversary of the vesting date. The TSR is calculated by dividing the sixty or ninety calendar day average price at end of the period (as applicable) and the reinvested dividends thereon by such sixty or ninety calendar day average price at start of the period. The maximum number of awards earned is capped at 200% of the target award. Additionally, no payout will be awarded in the event that the TSR at the vesting date reflects less than a 25% return from the average price at the grant date. These share units are similar to the share units granted prior to fiscal 2016, except that under these awards, the targets are more difficult to achieve as they are tied to the TSR of a defined peer group. The fair value of these awards is estimated at the date of grant, using a Monte Carlo Simulation.
The Company recognizes compensation expense using the straight-line method over the life of the market condition-based awards except for those issued to certain retirement-eligible participants, which are expensed on an accelerated basis.
In fiscal 2019 and fiscal 2020, the Company granted performance condition-based awards (“PSU”). A participant may earn between 0% to 200% of the number of awards granted, based on the Company’s cumulative adjusted earnings per share performance over a three-year period. The vesting of these awards is contingent upon meeting or exceeding performance conditions. The awards cliff vest on the third anniversary of the date of grant and are settled in common stock on the first anniversary of the vesting date. The maximum number of awards earned is capped at 200% of the target award. Expense for the
72

Table of Contents
performance condition-based award is recorded when the achievement of the performance condition is considered probable of achievement and is recorded on a straight-line basis over the requisite service period. If such performance criteria are not met, no compensation cost is recognized, and any recognized compensation cost is reversed. The closing stock price on the date of grant, adjusted for a discount to reflect the illiquidity inherent in the PSUs, represents the grant-date fair value for these awards.
Restricted Stock Units
The fair value of restricted stock units is based on the closing market price of the Company’s common stock on the date of grant. These awards generally vest, and are settled in common stock, at 25% per year, over a four-year period from the date of grant. The Company recognizes compensation expense using the straight-line method over the life of the restricted stock units.
Stock Options
The fair value of the options granted is estimated at the date of grant using the Black-Scholes option-pricing model utilizing assumptions based on historical data and current market data. The assumptions include expected term of the options, risk-free interest rate, expected volatility, and dividend yield. The expected term represents the expected amount of time that options granted are expected to be outstanding, based on historical and forecasted exercise behavior. The risk-free rate is based on the rate at the grant date of zero-coupon U.S. Treasury Notes with a term equal to the expected term of the option. Expected volatility is estimated using historical volatility rates based on historical weekly price changes over a term equal to the expected term of the options. The Company’s dividend yield is based on historical data. The Company recognizes compensation expense using the straight-line method over the vesting period of the options except for those issued to certain retirement-eligible participants, which are expensed on an accelerated basis.
Forfeitures
Forfeitures of share-based awards are estimated at the time of grant and revised, if necessary, in subsequent periods if actual
forfeitures differ from those estimates.
Earnings Per Share
Basic earnings per common share (“EPS”) are computed by dividing net earnings attributable to EnerSys stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. At March 31, 2021, 2020 and 2019, the Company had outstanding stock options, restricted stock units, market condition and performance condition-based awards, which could potentially dilute basic earnings per share in the future.
Segment Reporting
Effective April 1, 2020, the Company's chief operating decision maker, or CODM (the Company's Chief Executive Officer), changed the manner in which he reviews financial information for purposes of assessing business performance and allocating resources, by focusing on the lines of business on a global basis, rather than on geographic basis. As a result of this change, the Company re-evaluated the identification of its operating segments and reportable segments and identified the following as its three new operating segments, based on lines of business:
•Energy Systems - uninterruptible power systems, or “UPS” applications for computer and computer-controlled systems, as well as telecommunications systems, switchgear and electrical control systems used in industrial facilities and electric utilities, large-scale energy storage and energy pipelines. Energy Systems also includes highly integrated power solutions and services to broadband, telecom, renewable and industrial customers, as well as thermally managed cabinets and enclosures for electronic equipment and batteries.
•Motive Power - power for electric industrial forklifts used in manufacturing, warehousing and other material handling applications, as well as mining equipment, diesel locomotive starting and other rail equipment; and
•Specialty - premium starting, lighting and ignition applications in transportation, energy solutions for satellites, military aircraft, submarines, ships and other tactical vehicles, as well as medical and security systems.
The new operating segments also represent the Company's reportable segments under ASC 280, Segment Reporting. All prior comparative periods presented have been recast to conform to these changes.

Recently Adopted Accounting Pronouncements
In June 2016, the FASB, issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326)”: Measurement of Credit Losses on Financial Instruments, which changes the recognition model for the impairment of financial instruments, including accounts receivable, loans and held-to-maturity debt securities, among others. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In contrast to previous guidance, which considers current information and events and utilizes a probable threshold, (an “incurred loss” model), ASU 2016–13 mandates an “expected loss” model. The expected loss model: (i) estimates the risk of loss even when risk is remote, (ii) estimates losses over the contractual life, (iii) considers past events, current conditions and reasonable supported forecasts and (iv) has no recognition threshold. The Company adopted the standard effective April 1, 2020 and the adoption did not have a material impact on the Company's operating results, financial position or cash flows.
The Company estimates the allowance for credit losses in relation to accounts receivable based on relevant qualitative and quantitative information about historical events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported accounts receivable. Subsequent to April 1, 2020, accounts receivable are recorded at amortized cost less an allowance for expected credit losses. The Company maintains an allowance for credit losses for the expected failure or inability of its customers to make required payments. The Company recognizes the allowance for expected credit losses at inception and reassesses quarterly, based on management’s expectation of the asset’s collectability. The allowance is based on multiple factors including historical experience with bad debts, the credit quality of the customer base, the aging of such receivables and current macroeconomic conditions, as well as management’s expectations of conditions in the future. The Company’s allowance for uncollectible accounts receivable is based on management’s assessment of the collectability of assets pooled together with similar risk characteristics. The Company then adjusts the historical credit loss percentage by current and forecasted economic conditions. The Company then includes a baseline credit loss percentage into the historical credit loss percentage for each aging category to reflect the potential impact of the current and economic conditions. Such a baseline calculation will be adjusted further if changes in the economic environment impacts the Company's expectation for future credit losses.
The following table sets forth the changes in the Company's allowance for doubtful accounts:

|  | Balance at Beginning of Period |  | Provision for Doubtful Debts |  | Write-offs, net of Recoveries and Other |  | Balance at End of Period
Fiscal year ended March 31, 2019 |  | $ | 12,643 |  |  | $ | 1,385 |  |  | $ | (3,215) |  |  | $ | 10,813 |
Fiscal year ended March 31, 2020 |  | 10,813 |  |  | 4,821 |  |  | (388) |  |  | 15,246 |
Fiscal year ended March 31, 2021 |  | 15,246 |  |  | 178 |  |  | (2,432) |  |  | 12,992 |

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848)”: Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional expedients to ease the financial reporting burdens of the expected market transition from London Interbank Offered Rate (LIBOR) to an alternative reference rate such as Secured Overnight Financing Rate (SOFR). The amendments in this ASU were effective immediately and may be applied to impacted contracts and hedges prospectively through December 31, 2022. The adoption of the ASU had no impact on the Company’s Consolidated Financial Statements for the period ended March 31, 2021.
Accounting Pronouncements Issued But Not Adopted as of March 31, 2021
In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740)”: Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The guidance is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The adoption is not expected to have a material impact on its consolidated financial statements.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions take into account historical and forward looking factors that the Company believes are reasonable, including, but not limited to, the potential impacts arising from the coronavirus pandemic of 2019 (“COVID-19”) and public and private sector policies and initiatives aimed at reducing its transmission. As the extent and
74

Table of Contents
duration of the impacts of COVID-19 remain unclear, the Company’s estimates and assumptions may evolve as conditions change. Actual results could differ significantly from those estimates.
Examples of significant estimates include the allowance for credit losses, the recoverability of property, plant and equipment, the incremental borrowing rate for lease liabilities, the recoverability of intangible assets and other long-lived assets, fair value measurements, including those related to financial instruments, goodwill and intangible assets, valuation allowances on tax assets, pension and postretirement benefit obligations, contingencies and the identification and valuation of assets acquired and liabilities assumed in connection with business combinations.
2. Revenue Recognition
The Company's revenues by reportable segments are presented in Note 23.
Service revenues for fiscal 2021, 2020 and 2019 amounted to $296,213, $270,704 and $157,236, respectively.
A small portion of the Company's customer arrangements oblige the Company to create customized products for its customers that require the bundling of both products and services into a single performance obligation because the individual products and services that are required to fulfill the customer requirements do not meet the definition for a distinct performance obligation. These customized products generally have no alternative use to the Company and the terms and conditions of these arrangements give the Company the enforceable right to payment for performance completed to date, including a reasonable profit margin. For these arrangements, control transfers over time and the Company measures progress towards completion by selecting the input or output method that best depicts the transfer of control of the underlying goods and services to the customer for each respective arrangement. Methods used by the Company to measure progress toward completion include labor hours, costs incurred and units of production. Revenues recognized over time for fiscal 2021, 2020 and 2019 amounted to $155,217, $142,153 and $100,809, respectively.
On March 31, 2021, the aggregate transaction price allocated to unsatisfied (or partially unsatisfied) performance obligations was approximately $115,775, of which, the Company estimates that approximately $93,941 will be recognized as revenue in fiscal 2022, $21,011 in fiscal 2023, $774 in fiscal 2024, $49 in fiscal 2025 and $0 in fiscal 2026.
Any payments that are received from a customer in advance, prior to the satisfaction of a related performance obligation and billings in excess of revenue recognized, are deferred and treated as a contract liability. Advance payments and billings in excess of revenue recognized are classified as current or non-current based on the timing of when recognition of revenue is expected. As of March 31, 2021, the current and non-current portion of contract liabilities were $15,992 and $2,072, respectively. As of March 31, 2020, the current and non-current portion of contract liabilities were $17,342 and $8,356, respectively. Revenues recognized during fiscal 2021 and fiscal 2020, that were included in the contract liability at the beginning of the year, amounted to $14,064 and $18,697, respectively.
Amounts representing work completed and not billed to customers represent contract assets and were $46,451 and $39,048 as of March 31, 2021 and March 31, 2020, respectively.
The Company uses historic customer product return data as a basis of estimation for customer returns and records the reduction of sales at the time revenue is recognized. At March 31, 2021, the right of return asset related to the value of inventory anticipated to be returned from customers was $4,271 and refund liability representing amounts estimated to be refunded to customers was $7,475.

3. Leases
The Company leases manufacturing facilities, distribution centers, office space, vehicles and other equipment under non-cancellable leases with initial terms typically ranging from 1 to 17 years. At contract inception, the Company reviews the terms of the arrangement to determine if the contract is or contains a lease. Guidance in Topic 842 is used to evaluate whether the contract has an identified asset; if the Company has the right to obtain substantially all economic benefits from the asset; and if it has the right to direct the use of the underlying asset. When determining if a contract has an identified asset, the Company considers both explicit and implicit assets, and whether the supplier has the right to substitute the asset. When determining if the Company has the right to obtain substantially all economic benefits from the asset, the Company considers the primary outputs of the identified asset throughout the period of use and determines if it receives greater than 90% of those benefits. When determining if it has the right to direct the use of an underlying asset, the Company considers if it has the right to direct how and for what purpose the asset is used throughout the period of use and if it controls the decision-making rights over the asset.
Lease terms may include options to extend or terminate the lease. The Company exercises its judgment to determine the term of those leases when extension or termination options are present and include such options in the calculation of the lease term when it is reasonably certain that the Company will exercise those options.
The Company has elected to include both lease and non-lease components in the determination of lease payments for all asset classes. Payments made to a lessor for items such as taxes, insurance, common area maintenance, or other costs commonly referred to as executory costs, are also included in lease payments if they are fixed. The fixed portion of these payments are included in the calculation of the lease liability, while any variable portion would be recognized as variable lease expenses, when incurred. Variable payments made to third parties for these, or similar costs, such as utilities, are not included in the calculation of lease payments.
Both finance and operating leases are reflected as liabilities on the commencement date of the lease based on the present value of the lease payments to be made over the lease term. As most of the leases do not provide an implicit rate, the Company has exercised judgment in electing the incremental borrowing rate based on the information available when the lease commences to determine the present value of future payments. Right-of-use assets are valued at the initial measurement of the lease liability, plus any initial direct costs or rent prepayments and reduced by any lease incentives and any deferred lease payments.
Operating lease expense is recognized on a straight-line basis over the lease term. Finance lease expense includes depreciation, which is recognized on a straight-line basis over the expected life of the leased asset, and interest expense, which is recognized following an effective interest rate method.
Short term leases with an initial term of 12 months or less are not presented on the balance sheet and expense is recognized as incurred. The current and non-current portion of operating lease liabilities are reflected in accrued expenses and other liabilities, respectively, on the consolidated balance sheets. The right-of use assets relating to operating and finance leases are reflected in other assets and property, plant and equipment, respectively, on the consolidated balance sheets.
The following table presents lease assets and liabilities and their balance sheet classification:

|  | Classification |  | As of March 31, 2021 |  | As of March 31, 2020

4. Acquisitions
The Company made no acquisitions in fiscal 2021. Acquisitions made in fiscal 2020 and fiscal 2019 are as follows:
NorthStar
On September 30, 2019, the Company completed the acquisition of N Holding, AB (“NorthStar”) for $77,777 in cash consideration and the assumption of $107,018 in debt, which was funded using existing cash and credit facilities. NorthStar, through its direct and indirect subsidiaries, manufactures and distributes thin plate pure lead (TPPL) batteries and battery enclosures. NorthStar has two large manufacturing facilities in Springfield, Missouri. The Company acquired tangible and intangible assets, including trademarks, technology, customer relationships and goodwill. Based on valuations performed, trademarks were valued at $6,000, technology at $19,000, customer relationships at $9,000, and goodwill was recorded at $76,784. As a result of the change in operating segments discussed in Note 23, goodwill associated with the acquisition of NorthStar has been allocated to the Energy Systems and Specialty segments on a relative fair value basis. The useful lives of technology were estimated at 10 years, customer relationships were estimated at 15 to 18 years and trademarks were estimated at 5 years. Goodwill deductible for tax purposes is $68,522.
During fiscal 2021, the Company finalized the measurement of all provisional amounts recognized in connection with the NorthStar business combination. The purchase accounting adjustments resulted in an increase to goodwill by $2,996 as a result of finalizing income tax accounting.
The results of the NorthStar acquisition have been included in the Company’s results of operations from the date of acquisition. Pro forma earnings and earnings per share computations have not been presented as this acquisition is not considered material.
Alpha
On December 7, 2018, the Company completed the acquisition of all of the issued and outstanding common stock of Alpha Technologies Services, Inc. (“ATS”) and Alpha Technologies Ltd. (“ATL”), resulting in ATS and ATL becoming wholly-owned subsidiaries of the Company (the “Alpha share purchase”). Additionally, the Company acquired substantially all of the assets of Alpha Technologies Inc. and certain assets of Altair Advanced Industries, Inc. and other affiliates of ATS and ATL (all such sellers, together with ATS and ATL, “Alpha”), in each case in accordance with the terms and conditions of certain restructuring agreements (collectively, the “Alpha asset acquisition” and together with the Alpha share purchase, the “Alpha acquisition”). Based in Bellingham, Washington, Alpha is a global industry leader in comprehensive commercial-grade energy solutions for broadband, telecom, renewable, industrial and traffic customers around the world. The initial purchase consideration for the Alpha acquisition was $750,000, of which $650,000 was paid in cash and the balance was settled by issuing 1,177,630 shares of EnerSys common stock. These shares were issued out of the Company's treasury stock and were valued at $84.92 per share, which was based on the thirty-day volume weighted average stock price of the Company’s common stock at closing, in accordance with the purchase agreement. The 1,177,630 shares had a closing date fair value of $93,268, based upon the December 7, 2018, closing date spot rate of $79.20. The total purchase consideration, consisting of cash paid of $650,000, shares valued at $93,268 and an adjustment for working capital (due post - closing from seller of $766) was $742,502. The Company funded the cash portion of the Alpha acquisition with borrowings from the Amended Credit Facility as defined in Note 10. See Note 10 for additional information.
The results of operations of Alpha have been included in the Company’s Energy Systems segment.
For the period ended March 31, 2019, that EnerSys owned Alpha, the contribution of the acquisition to net sales was $162,454 and net loss of $1,252, excluding the effect of the transaction and integration costs, and interest expense on the debt to finance the acquisition.

Impairment of goodwill, finite and indefinite-lived intangibles
Goodwill is tested annually for impairment during the fourth quarter or earlier upon the occurrence of certain events or substantive changes in circumstances that indicate goodwill is more likely than not impaired. The Company did not record any impairment relating to its goodwill and intangible assets during fiscal 2021 and 2019.
In the fourth quarter of fiscal 2020, the Company conducted its annual goodwill impairment test which indicated that the fair value of its legacy Asia reporting unit was less than its carrying value. The Company recorded a non-cash charge of $39,713 related to goodwill impairment in Asia under the caption “Impairment of goodwill” in the Consolidated Statements of Income. The Company also recorded a non-cash charge of $4,549 related to impairment of indefinite-lived trademarks in its legacy EMEA reportable segment under the caption “Impairment of indefinite-lived intangibles” in the Consolidated Statements of Income. The key factors contributing to the impairment in Asia was the increasing pressure on organic sales growth that the Company began to experience in fiscal 2019 due to a slowdown in telecom spending in the People's Republic of China (“PRC”) amidst growing trade tensions between the U.S.A and China. The impact of these trade tensions on the Company's ability to capture market share in the PRC accelerated in the second half of the fiscal year. Throughout fiscal 2020, there was a general slowdown in the Chinese economy which was further exacerbated by the outbreak of the COVID -19 pandemic, causing disruption to two of the Company's plants in China in the fourth quarter. Also contributing to the poor performance of the Asia region was a general softening of demand in Australia, that began in fiscal 2019 and continued throughout fiscal 2020. The Company monitored the performance of its Asia reporting unit for interim impairment indicators throughout fiscal 2020, but the emergence of COVID-19 in China in December 2019 coupled with the totality of economic headwinds in the region resulted in the recognition of a goodwill impairment loss in connection with its annual impairment test.
During the fourth quarter of fiscal 2020, management completed its evaluation of key inputs used to estimate the fair value of its indefinite-lived trademarks and determined that an impairment charge relating to two of its trademarks in EMEA, that were acquired through legacy acquisitions was appropriate, as it plans to phase out these trademarks.
The Company estimated tax-deductible goodwill to be approximately $110,063 and $120,708 as of March 31, 2021 and 2020, respectively.

2017 Credit Facility and Subsequent Amendment
In fiscal 2018, the Company entered into a credit facility (the “2017 Credit Facility”). The 2017 Credit Facility scheduled to mature on September 30, 2022, initially comprised a $600,000 senior secured revolving credit facility (“2017 Revolver”) and a $150,000 senior secured term loan (“2017 Term Loan”). The Company utilized the borrowings from the 2017 Credit Facility to repay its pre-existing credit facility.
In fiscal 2019, the Company amended the 2017 Credit Facility (as amended, the “Amended Credit Facility”) to fund the Alpha acquisition. The Amended Credit Facility consists of $449,105 senior secured term loans (the “Amended 2017 Term Loan”), including a CAD 133,050 ($99,105) term loan and a $700,000 senior secured revolving credit facility (the “Amended 2017 Revolver”). The amendment resulted in an increase of the 2017 Term Loan and the 2017 Revolver by $299,105 and $100,000, respectively.
Subsequent to the amendment, the quarterly installments payable on the Amended 2017 Term Loan are $5,645 beginning December 31, 2018, $8,468 beginning December 31, 2019 and $11,290 beginning December 31, 2020 with a final payment of $320,000 on September 30, 2022. The Amended Credit Facility may be increased by an aggregate amount of $325,000 in revolving commitments and /or one or more new tranches of term loans, under certain conditions. Both the Amended 2017 Revolver and the Amended 2017 Term Loan bear interest, at the Company's option, at a rate per annum equal to either (i) the London Interbank Offered Rate (“LIBOR”) or Canadian Dollar Offered Rate (“CDOR”) plus (i) LIBOR plus between 1.25% and 2.00% (currently 1.25% and based on the Company's consolidated net leverage ratio) or (ii) the U.S. Dollar Base Rate (which equals, for any day a fluctuating rate per annum equal to the highest of (a) the Federal Funds Effective Rate plus 0.50%, (b) Bank of America “Prime Rate” and (c) the Eurocurrency Base Rate plus 1%; provided that, if the Base Rate shall be less than zero, such rate shall be deemed zero) (iii) the CDOR Base Rate equal to the higher of (a) Bank of America “Prime Rate” and (b) average 30-day CDOR rate plus 0.50%. Obligations under the Amended Credit Facility are secured by substantially all of the Company’s existing and future acquired assets, including substantially all of the capital stock of the Company’s United States subsidiaries that are guarantors under the Amended Credit Facility and up to 65% of the capital stock of certain of the Company’s foreign subsidiaries that are owned by the Company’s United States subsidiaries.
The Amended Credit Facility allows for up to two temporary increases in the maximum leverage ratio from 3.50x to 4.00x for a four quarter period following an acquisition larger than $250,000. Effective December 7, 2018 through December 28, 2019, the maximum leverage ratio was increased to 4.00x. On December 29, 2019, the maximum leverage ratio returned to 3.50x.
As of March 31, 2021, the Company had $0 outstanding under the Amended 2017 Revolver and $376,039 under the Amended 2017 Term Loan.
The current portion of the Amended 2017 Term Loan of $45,579 is classified as long-term debt as the Company expects to refinance the future quarterly payments with revolver borrowings under the Amended Credit Facility.
Interest Rates on Long Term Debt
The weighted average interest rate on the long term debt at March 31, 2021 and March 31, 2020, was 3.5% and 3.7%, respectively.

Total derivatives |  | $ | (2,432) |  |  | $ | — |  |  | $ | (2,432) |  |  | $ | — |

The fair values of lead forward contracts are calculated using observable prices for lead as quoted on the London Metal Exchange (“LME”) and, therefore, were classified as Level 2 within the fair value hierarchy as described in Note 1, Summary of Significant Accounting Policies.
The fair values for foreign currency forward contracts are based upon current quoted market prices and are classified as Level 2 based on the nature of the underlying market in which these derivatives are traded.
Financial Instruments
The fair values of the Company’s cash and cash equivalents approximate carrying value due to their short maturities.
The fair value of the Company’s short-term debt and borrowings under the Amended Credit Facility (as defined in Note 10), approximate their respective carrying value, as they are variable rate debt and the terms are comparable to market terms as of the balance sheet dates and are classified as Level 2.
The fair value of the Company's 2027 Notes and 2023 Notes, (collectively, the “Senior Notes”) represent the trading values based upon quoted market prices and are classified as Level 2. The 2027 Notes were trading at approximately 102% and 94% of face value on March 31, 2021 and March 31, 2020, respectively. The 2023 Notes were trading at approximately 105% and 97% of face value on March 31, 2021 and March 31, 2020, respectively.

(2)The fair value amount of the Senior Notes at March 31, 2021 and March 31, 2020 represent the trading value of the instruments.
Non-recurring fair value measurements
The valuation of goodwill and other intangible assets is based on information and assumptions available to the Company at the time of acquisition, using income and market approaches to determine fair value. The Company tests goodwill and other intangible assets annually for impairment, or when indications of potential impairment exist (see Note 1).
Goodwill is tested for impairment by determining the fair value of the Company’s reporting units. The unobservable inputs used to measure the fair value of the reporting units include projected growth rates, profitability, and the risk factor premium added to the discount rate. The remeasurement of the reporting unit fair value is classified as a Level 3 fair value assessment due to the significance of unobservable inputs developed using company-specific information.
The inputs used to measure the fair value of other intangible assets were largely unobservable and accordingly were also classified as Level 3. The fair value of trademarks is based on an estimate of the royalties saved that would have been paid to a third party had the Company not owned the trademark. The fair value of other indefinite-lived intangibles was estimated using the income approach, based on cash flow projections of revenue growth rates, taking into consideration industry and market conditions.
In connection with the annual impairment testing conducted as of December 30, 2019 for fiscal 2020, two of the Company's indefinite-lived trademarks, that were acquired through legacy acquisitions were recorded at fair value on a non-recurring basis at $1,700 and the remeasurement resulted in an impairment of $4,549. In determining the fair value of these assets, the Company used a royalty rate of 1.25% based on comparable market rates and used a discount rate of 13.0%.
These impairment charges relating to goodwill and indefinite-lived trademarks are included under the captions Impairment of goodwill and Impairment of indefinite-lived intangibles in the Consolidated Statements of Income.
On November 11, 2020, the Company committed to a plan to substantially close its facility in Hagen, Germany, which produces flooded motive power batteries for forklifts. Management determined that future demand for the motive power batteries produced at this facility was not sufficient, given the conversion from flooded to maintenance free batteries by customers, the existing number of competitors in the market, as well as the near term decline in demand and increased uncertainty from the pandemic. As a result, the Company concluded that the carrying value of the asset group is not recoverable and recorded a write-off of $3,975 of the fixed assets to their estimated fair value of $14,456, which was recognized in the third quarter of fiscal 2021. The valuation technique used to measure the fair value of fixed assets was a combination of the income and market approaches. The inputs used to measure the fair value of these fixed assets under the income approach were largely unobservable and accordingly were classified as Level 3.
On March 5, 2019, the Company committed to a plan to close its facility in Targovishte, Bulgaria, which produced diesel-electric submarine batteries. Management determined that the future demand for batteries of diesel-electric submarines was not sufficient given the number of competitors in the market. As a result, the Company concluded that the carrying value of the asset group is not recoverable and recorded a write-off of $14,958 in the fixed assets to their estimated fair value of $242, which was recognized in the fourth quarter of fiscal 2019. The valuation technique used to measure the fair value of fixed assets was a

combination of the income and market approaches. The inputs used to measure the fair value of these fixed assets under the income approach were largely unobservable and accordingly were classified as Level 3.
13. Derivative Financial Instruments
The Company utilizes derivative instruments to reduce its exposure to fluctuations in commodity prices and foreign exchange rates, under established procedures and controls. The Company does not enter into derivative contracts for speculative purposes. The Company’s agreements are with creditworthy financial institutions and the Company anticipates performance by counterparties to these contracts and therefore no material loss is expected.
Derivatives in Cash Flow Hedging Relationships
Lead Forward Contracts
The Company enters into lead forward contracts to fix the price for a portion of its lead purchases. Management considers the lead forward contracts to be effective against changes in the cash flows of the underlying lead purchases. The vast majority of such contracts are for a period not extending beyond one year. At March 31, 2021 and 2020, the Company has hedged the price to purchase approximately 54.5 million pounds and 35.0 million pounds of lead, respectively, for a total purchase price of $50,567 and $30,078, respectively.
Foreign Currency Forward Contracts
The Company uses foreign currency forward contracts and options to hedge a portion of the Company’s foreign currency exposures for lead, as well as other foreign currency exposures so that gains and losses on these contracts offset changes in the underlying foreign currency denominated exposures. The vast majority of such contracts are for a period not extending beyond one year. As of March 31, 2021 and 2020, the Company had entered into a total of $26,033 and $34,008, respectively, of such contracts.
In the coming twelve months, the Company anticipates that $597 of pretax gain relating to lead and foreign currency forward contracts will be reclassified from AOCI as part of cost of goods sold. This amount represents the current net unrealized impact of hedging lead and foreign exchange rates, which will change as market rates change in the future, and will ultimately be realized in the Consolidated Statements of Income as an offset to the corresponding actual changes in lead costs to be realized in connection with the variable lead cost and foreign exchange rates being hedged.
Derivatives not Designated in Hedging Relationships
Foreign Currency Forward Contracts
The Company also enters into foreign currency forward contracts to economically hedge foreign currency fluctuations on intercompany loans and foreign currency denominated receivables and payables. These are not designated as hedging instruments and changes in fair value of these instruments are recorded directly in the Consolidated Statements of Income. As of March 31, 2021 and 2020, the notional amount of these contracts was $28,995 and $42,232, respectively.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was signed into law in the U.S. to provide certain relief as a result of the COVID-19 pandemic. In addition, governments around the world have enacted or implemented various forms of tax relief measures in response to the economic conditions in the wake of COVID-19. As of March 31, 2021, neither the CARES Act nor changes to income tax laws or regulations in other jurisdictions had a significant impact on the Company’s effective tax rate.

The Company has approximately $1,078 in United States federal net operating loss carryforwards, all of which are limited by Section 382 of the Internal Revenue Code, with expirations between 2023 and 2027. The Company has approximately $235,225 of foreign net operating loss carryforwards, of which $186,816 may be carried forward indefinitely and $48,409 expire between fiscal 2022 and fiscal 2041. In addition, the Company also has approximately $28,955 of state net operating loss carryforwards with expirations between fiscal 2022 and fiscal 2041.

The effective income tax rates for the fiscal years ended March 31, 2021, 2020 and 2019 were 15.7%, 6.7% and 11.9%, respectively. The effective income tax rate with respect to any period may be volatile based on the mix of income in the tax jurisdictions in which the Company operates and the amount of its consolidated income before taxes. The rate increase in fiscal 2021 compared to fiscal 2020 is primarily due to Swiss tax reform, partially offset by the Hagen, Germany exit charges and changes in the mix of earnings among tax jurisdictions. The rate decrease in fiscal 2020 compared to fiscal 2019 is primarily due to changes in mix of earnings among tax jurisdictions, Swiss tax reform, and items related to the Tax Act in fiscal 2019.
On May 19, 2019, a public referendum held in Switzerland approved the Federal Act on Tax Reform and AHV (Old-Age and Survivors Insurance) Financing (TRAF) as adopted by the Swiss Federal Parliament on September 28, 2018. The Swiss tax reform measures were effective January 1, 2020. The Company recorded a net deferred tax asset of $22,500 during fiscal 2020, related to the amortizable goodwill and based on further evaluation with the Swiss tax authority, recorded an additional income tax benefit of $1,883 during fiscal 2021.
In fiscal 2021, the foreign effective income tax rate on foreign pre-tax income of $114,080 was 6.8%. In fiscal 2020, the foreign effective income tax rate on foreign pre-tax income of $110,744 was (7.4)% and in fiscal 2019, the foreign effective income tax rate on foreign pre-tax income of $128,872 was 12.3%. The rate increase in fiscal 2021 compared to fiscal 2020 is primarily due to Swiss tax reform, partially offset by the Hagen, Germany exit charges and changes in the mix of earnings among tax jurisdictions. The rate decrease in fiscal 2020 compared to fiscal 2019 is primarily due to Swiss tax reform and changes in the mix of earnings among tax jurisdictions.
Income from the Company's Swiss subsidiary comprised a substantial portion of its overall foreign mix of income for the fiscal years ended March 31, 2021, 2020 and 2019 and was taxed, excluding the impact from the Swiss tax reform, at approximately 8%, 3% and 4%, respectively.
The Company has approximately $1,591,000 and $1,376,000 of undistributed earnings of foreign subsidiaries for fiscal years 2021 and 2020, respectively. During fiscal 2021, previously undistributed earnings of certain foreign subsidiaries were no longer considered indefinitely reinvested. As a result, no additional income taxes have been provided as the Company had previously recognized a one-time transition tax on these earnings under the Tax Act. The Company intends to continue to be indefinitely reinvested on the remaining undistributed foreign earnings and outside basis differences and therefore, no additional income taxes have been provided.

All of the balance of unrecognized tax benefits at March 31, 2021, if recognized, would be included in the Company’s Consolidated Statements of Income and have a favorable impact on both the Company’s net earnings and effective tax rate.
The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2010.
While the net effect on total unrecognized tax benefits cannot be reasonably estimated, approximately $1,850 is expected to reverse in fiscal 2022 due to expiration of various statute of limitations.
The Company recognizes tax related interest and penalties in income tax expense in its Consolidated Statements of Income. As of March 31, 2021 and 2020, the Company had an accrual of $400 and $285, respectively, for interest and penalties.

Assumptions
Significant assumptions used to determine the net periodic benefit cost for the U.S. and International plans were as follows:

|  | United States Plans |  | International Plans
|  | Fiscal year ended March 31, |  | Fiscal year ended March 31,
|  | 2021 |  | 2020 |  | 2019 |  | 2021 |  | 2020 |  | 2019

N/A = not applicable
Significant assumptions used to determine the projected benefit obligations for the U.S. and International plans were as follows:

|  | United States Plans |  | International Plans
|  | March 31, |  | March 31,
|  | 2021 |  | 2020 |  | 2021 |  | 2020
Discount rate |  | 3.0 | % |  | 3.0 | % |  | 0.5%-2.3% |  | 1.3%-2.3%
Rate of compensation increase |  | N/A |  | N/A |  | 1.5-4.0 |  | 2.0-3.5

N/A = not applicable
The United States plans do not include compensation in the formula for determining the pension benefit as it is based solely on years of service.
The expected long-term rate of return for the Company’s pension plan assets is based upon the target asset allocation and is determined using forward looking assumptions in the context of historical returns and volatilities for each asset class, as well as correlations among asset classes. The Company evaluates the rate of return assumptions for each of its plans on an annual basis.
Pension Plan Investment Strategy
The Company’s investment policy emphasizes a balanced approach to investing in securities of high quality and ready marketability. Investment flexibility is encouraged so as not to exclude opportunities available through a diversified investment strategy.
Equity investments are maintained within a target range of 40% - 75% of the total portfolio market value for the U.S. plans and with a target of approximately 65% for international plans. Investments in debt securities include issues of various maturities, and the average quality rating of bonds should be investment grade with a minimum quality rating of “B” at the time of purchase.
The Company periodically reviews the asset allocation of its portfolio. The proportion committed to equities, debt securities and cash and cash equivalents is a function of the values available in each category and risk considerations. The plan’s overall return will be compared to and is expected to meet or exceed established benchmark funds and returns over a three to five year period.
The objectives of the Company’s investment strategies are: (a) the achievement of a reasonable long-term rate of total return consistent with an emphasis on preservation of capital and purchasing power, (b) stability of annual returns through a portfolio that reflects a conservative mix of risk versus return, and (c) reflective of the Company’s willingness to forgo significantly above-average rewards in order to minimize above-average risks. These objectives may not be met each year but should be attained over a reasonable period of time.

Exit Charges
Fiscal 2021 Programs
Hagen, Germany
On November 10, 2020, the EnerSys’ Board of Directors approved a plan to substantially close its facility in Hagen, Germany, which produces flooded motive power batteries for forklifts. Management determined that future demand for the motive power batteries produced at this facility was not sufficient, given the conversion from flooded to maintenance free batteries by customers, the existing number of competitors in the market, as well as the near term decline in demand and increased
uncertainty from the pandemic. The Company plans to retain the facility with limited sales, service and administrative functions along with related personnel for the foreseeable future.
The Company currently estimates that the total charges for these actions will amount to approximately $60,000, the majority of which are expected to be recorded by the end of calendar 2021. Cash charges of approximately $40,000 are primarily for employee severance related payments, but also include payments for cleanup related to the facility, contractual releases and legal expenses. Non-cash charges from inventory and equipment write-offs are estimated to be $20,000. These actions will result in the reduction of approximately 200 employees.
During fiscal 2021, the Company recorded cash charges relating to severance of $23,331 and non-cash charges of $7,946 primarily relating to fixed asset write-offs.
Vijayawada, India
During fiscal 2021, the Company committed to a plan to close its facility in Vijayawada, India to align with its strategic vision for the new line of business structure and footprint and recorded exit charges of $1,509, primarily relating to asset write-offs.
Targovishte, Bulgaria
During fiscal 2019, the Company committed to a plan to close its facility in Targovishte, Bulgaria, which produced diesel-electric submarine batteries. Management determined that the future demand for batteries of diesel-electric submarines was not sufficient given the number of competitors in the market. Of the estimated total charges of $26,000 for this plan, the Company had recorded charges amounting to $20,242 in fiscal 2019, relating to severance and inventory and fixed asset write-offs and an additional $5,123 relating to cash and non-cash charges during fiscal 2020. During fiscal 2021, in keeping with its strategy of exiting the manufacture of batteries for diesel-electric submarines, the Company completed further actions which resulted in $220 relating to cash and non-cash charges.

Fiscal 2020 Programs
During fiscal 2020, in keeping with its strategy of exiting the manufacture of batteries for diesel-electric submarines, the Company also sold certain licenses and assets for $2,031 and recorded a net gain of $892, which were reported as other exit charges in the Specialty segment.
During fiscal 2020, the Company also wrote off $5,441 of assets at its Kentucky and Tennessee Motive Power plants, as a result of its strategic product mix shift from traditional flooded batteries to maintenance free lead acid and lithium batteries.
Fiscal 2019 Programs
During fiscal 2019, the Company recorded exit charges of $4,930 relating to the disposition of GAZ Geräte- und Akkumulatorenwerk Zwickau GmbH, a wholly-owned German subsidiary and $957 relating to dissolving a joint venture in Tunisia. These exit activities are a consequence of the Company's strategic decision to streamline its product portfolio and focus its efforts on new technologies.
During fiscal 2019, as part of the aforementioned program to convert its India operations from mainly reserve power production to motive power production, the Company recorded a non-cash write off of reserve power inventories of $526, which was reported in cost of goods sold and a $660 noncash write-off related to reserve power fixed assets in restructuring charges.
Richmond, Kentucky Plant Fire
During fiscal 2021, the Company settled its claims with its insurance carrier relating to the fire that broke out in the battery formation area of the Company's Richmond, Kentucky motive power production facility in fiscal 2020. The total claims, for both property and business interruption of $46,117 were received through March 31, 2021.
The final settlement of insurance recoveries and finalization of costs related to the replacement of property, plant and equipment, resulted in a net gain of $4,397, which was recorded as a reduction to operating expenses in the Consolidated Statements of Income.
The details of charges and recoveries for fiscal 2021 and fiscal 2020 are as follows:
In fiscal 2020, the Company recorded as a receivable, $17,037, consisting of write-offs for damages caused to its fixed assets and inventories, as well as for cleanup, asset replacement and other ancillary activities directly associated with the fire and received $12,000 related to its initial claims.
During fiscal 2021, the Company recorded an additional $16,580 as a receivable for cleanup and received $21,617 from the insurance carrier.
In addition to the property damage claim, the Company received $12,500 in business interruption claims, of which $5,000 was recorded in fiscal 2020 and $7,500 in fiscal 2021, and was credited to cost of goods sold, in the respective periods.

23. Business Segments
Effective April 1, 2020, the Company's chief operating decision maker, or CODM (the Company's Chief Executive Officer), changed the manner in which he reviews financial information for purposes of assessing business performance and allocating resources, by focusing on the lines of business on a global basis, rather than on geographic basis. As a result of this change, the Company re-evaluated the identification of its operating segments and reportable segments and identified the following as its three new operating segments, based on lines of business:
•Energy Systems - uninterruptible power systems, or “UPS” applications for computer and computer-controlled systems, as well as telecommunications systems, switchgear and electrical control systems used in industrial facilities and electric utilities, large-scale energy storage and energy pipelines. Energy Systems also includes highly integrated power solutions and services to broadband, telecom, renewable and industrial customers, as well as thermally managed cabinets and enclosures for electronic equipment and batteries.
•Motive Power - power for electric industrial forklifts used in manufacturing, warehousing and other material handling applications, as well as mining equipment, diesel locomotive starting and other rail equipment; and
•Specialty - premium starting, lighting and ignition applications in transportation, energy solutions for satellites, military aircraft, submarines, ships and other tactical vehicles, as well as medical and security systems.
The new operating segments also represent the Company's reportable segments under ASC 280, Segment Reporting. All prior comparative periods presented have been recast to conform to these changes.
