CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
The Private Securities Litigation Reform Act of 1995 (the “Reform Act”) provides a safe harbor for forward-looking statements made by or on behalf of EnerSys. EnerSys and its representatives may, from time to time, make written or verbal forward-looking statements, including statements contained in EnerSys' filings with the Securities and Exchange Commission ( “SEC”) and its reports to stockholders. Generally, the inclusion of the words “anticipate,” “believe,” “expect,” “future,” “intend,” “estimate,” “will,” “plans,” or the negative of such terms and similar expressions identify statements that constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 and that are intended to come within the safe harbor protection provided by those sections. All statements addressing operating performance, events, or developments that EnerSys expects or anticipates will occur in the future, including statements relating to sales growth, earnings or earnings per share growth, and market share, as well as statements expressing optimism or pessimism about future operating results, are forward-looking statements within the meaning of the Reform Act. The forward-looking statements are and will be based on management’s then-current beliefs and assumptions regarding future events and operating performance and on information currently available to management, and are applicable only as of the dates of such statements.
Forward-looking statements involve risks, uncertainties and assumptions. Although we do not make forward-looking statements unless we believe we have a reasonable basis for doing so, we cannot guarantee their accuracy. Actual results may differ materially from those expressed in these forward-looking statements due to a number of uncertainties and risks, including the risks described in this Annual Report on Form 10-K and other unforeseen risks. You should not put undue reliance on any forward-looking statements.

ITEM 1. | BUSINESS

Overview
EnerSys (the “Company,” “we,” or “us”) is the world’s largest manufacturer, marketer and distributor of industrial batteries. We also manufacture, market and distribute products such as battery chargers, power equipment, battery accessories, and outdoor cabinet enclosures. Additionally, we provide related aftermarket and customer-support services for our products. We market our products globally to over 10,000 customers in more than 100 countries through a network of distributors, independent representatives and our internal sales force.
We operate and manage our business in three geographic regions of the world—Americas, EMEA and Asia, as described below. Our business is highly decentralized with manufacturing locations throughout the world. More than half of our manufacturing capacity is located outside of the United States, and approximately 50% of our net sales were generated outside of the United States. The Company has three reportable business segments based on geographic regions, defined as follows:

• | Americas, which includes North and South America, with our segment headquarters in Reading, Pennsylvania, U.S.A.;

• | EMEA, which includes Europe, the Middle East and Africa, with our segment headquarters in Zug, Switzerland; and

• | Asia, which includes Asia, Australia and Oceania, with our segment headquarters in Singapore.

We have two primary product lines: reserve power and motive power products. Net sales classifications by product line are as follows:

• | Reserve power products are used for backup power for the continuous operation of critical applications in telecommunications systems, uninterruptible power systems, or “UPS” applications for computer and computer-controlled systems, and other specialty power applications, including medical and security systems, premium starting, lighting and ignition applications, in switchgear, electrical control systems used in electric utilities, large-scale energy storage, energy pipelines, in commercial aircraft, satellites, military aircraft, submarines, ships and tactical vehicles. Reserve power products also include thermally managed cabinets and enclosures for electronic equipment and batteries.

• | Motive power products are used to provide 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.

Additionally, see Note 22 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 2017”, which refers to our fiscal year ended March 31, 2017. 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 2017 ended on July 3, 2016, October 2, 2016, January 1, 2017, and March 31, 2017, respectively. The four quarters in fiscal 2016 ended on June 28, 2015, September 27, 2015, December 27, 2015, and March 31, 2016, 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. (“ESG”). Our successful integration of ESG provided global scale in both the reserve and motive power markets. The ESG acquisition also provided us with a further opportunity to reduce costs and improve operating efficiency.
During fiscal years 2003 through 2017, we made twenty-seven acquisitions around the globe. In fiscal 2016, we completed the acquisition of ICS Industries Pty. Ltd. (ICS), headquartered in Melbourne, Australia. ICS is a leading full line shelter designer and manufacturer with installation and maintenance services serving the telecommunications, utilities, datacenter, natural resources and transport industries operating in Australia and serving customers in the Asia Pacific region.
Effective April 1, 2016, David Shaffer became our new President and Chief Executive Officer and Todd Sechrist became our new Executive Vice President and Chief Operating Officer of EnerSys. In addition, we hired a Chief Technical Officer, who reviewed our existing product portfolio and development programs and generated a new product roadmap.
We also hired a Vice President - Business Development to expand our capabilities to identify, review and execute M & A transitions. Mr. Shaffer and senior management of the company have performed a company-wide strategic review of our operations, product portfolio, enterprise systems and management capabilities, which resulted in the following key action items:
Develop operational excellence priorities to:

• | Update and upgrade our digital core;

• | Implement Lean initiatives to further substantial productivity gains; and

• | Invest in productivity and capacity automation.

Our goal is to improve our operating margins by a minimum of 200 basis points by the end of fiscal 2021.
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 5% of our revenues.
Our reserve power customers consist of both global and regional customers. These customers are in diverse markets including telecom, UPS, electric utilities, security systems, emergency lighting, premium starting, lighting and ignition applications and space satellites. In addition, we sell our aerospace and defense products in numerous countries, including the governments of the U.S., Germany and the U.K. and to major defense and aviation original equipment manufacturers (“OEMs”).
Our motive power products are sold to a large, diversified customer base. These customers include material handling equipment dealers, OEMs and end users of such equipment. End users include manufacturers, distributors, warehouse operators, retailers, airports, mine operators and railroads.
Distribution and Services
We distribute, sell and service reserve and motive power 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
7

Table of Contents
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 battery market is highly competitive both among competitors who manufacture and sell industrial batteries and among customers who purchase industrial batteries. 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.
Americas
We believe that we have the largest market share in the Americas industrial battery market. We compete principally with East Penn Manufacturing, Exide Technologies and New Power in both the reserve and motive products markets; and also C&D Technologies Inc., EaglePicher (OM Group), NorthStar Battery, SAFT as well as Chinese producers in the reserve products market.
EMEA
We believe that we have the largest market share in the European industrial battery market. Our primary competitors are Exide Technologies, FIAMM, Hoppecke, SAFT as well as Chinese producers in the reserve products market; and Exide Technologies, Hoppecke, Midac, Eternity, and TAB in the motive products market.
Asia
We have a small share of the fragmented Asian industrial battery market. We compete principally with GS-Yuasa, Shin-Kobe, Hoppecke and Zibo Torch in the motive products market; and Amara Raja, China Shoto, Coslight, Exide Industries, Leoch and Narada, in the reserve products market.
Warranties
Warranties for our products vary geographically and by product type and are competitive with other suppliers of these types of products. Generally, our reserve power product warranties range from one to twenty years and our motive power product warranties range from one to seven years. 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 leaders in thin plate pure lead technology (“TPPL”). Some aspects of this technology may be patented in the future. 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
8

Table of Contents
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, but historically our fourth quarter is our best quarter with higher revenues and generally more working days and 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 and optimization of new battery products using existing technologies, which, in certain cases, differentiate our stored energy solutions from that of our competition. 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.

Employees
At March 31, 2017, we had approximately 9,400 employees. Of these employees, approximately 29% were covered by collective bargaining agreements. Employees covered by collective bargaining agreements that did not exceed twelve months were approximately 7% of the total workforce. The average term of these agreements is two years, with the longest term being three years. We consider our employee relations to be good. We did not experience any significant labor unrest or disruption of production during fiscal 2017.
Environmental Matters
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.
Sumter, South Carolina
We currently are responsible for certain environmental obligations at our former battery facility in Sumter, South Carolina, that predate our ownership of this facility. This battery facility was closed in 2001 and is separate from our current metal fabrication
9

Table of Contents
facility in Sumter. We have a reserve for this facility that totaled $1.1 million as of March 31, 2017. Based on current information, we believe this reserve is adequate to satisfy our environmental liabilities at this facility.
Environmental and safety certifications
Twenty 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 Europe and one in Africa are certified to OHSAS 18001 standards. OHSAS 18001 is a globally recognized occupational health and safety management systems standard.
Quality Systems
We utilize a global strategy for quality management systems, policies and procedures, the basis of which is the ISO 9001:2008 standard, which is a worldwide recognized quality standard. We believe in the principles of this standard and reinforce this by requiring mandatory compliance for all manufacturing, sales and service locations globally that are registered to the ISO 9001 standard. This strategy enables us to provide consistent quality products and services to meet our customers’ needs.

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.
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
10

Table of Contents
results will vary by geographic segment, 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 segment, 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. For example, certain of the Company’s European subsidiaries have received subpoenas and requests for documents and, in some cases, interviews from, and have had on-site inspections conducted by the competition authorities of Belgium, Germany and the Netherlands relating to conduct and anticompetitive practices of certain industrial battery participants. The Company is responding to inquiries related to these matters. The Company settled the Belgian regulatory proceeding in February 2016 by acknowledging certain anticompetitive practices and conduct and agreeing to pay a fine of $2.0 million, which was paid in March 2016. As of March 31, 2017, the Company had a reserve balance of $1.8 million relating to the Belgian regulatory proceeding, $10.3 million relating to the Dutch regulatory proceeding and $13.5 million to a portion of the German regulatory proceeding and does not believe that an estimate can be made at this time given the current stage of a portion of the German regulatory proceeding. (See Note 18 to the Consolidated Financial Statement).
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) lead 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 lead 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.
Our operations expose us to litigation, tax, environmental and other legal compliance risks.
11

Table of Contents
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 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. 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. 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
12

Table of Contents
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 a EU-wide conflict minerals rule under which most EU importers of tin, tungsten, tantalum, gold and their ores will have to conduct due 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 is required by 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 50% of net sales were generated outside of the United States for the last three fiscal years.
Most of the risk of fluctuating foreign currencies is in our EMEA segment, 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 segments are not as significant as our EMEA segment, 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 may 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 may experience significant delays, increased costs and other difficulties. Any significant disruption or deficiency in the design and implementation of the ERP could 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 effected.
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, Bulgaria, Canada, the Czech Republic, France, Germany, India, Italy, Malaysia, Mexico, the People’s Republic of China (“PRC”), Poland, Spain, Switzerland, Tunisia and the United Kingdom. We may face political instability, economic uncertainty, and/or difficult labor relations in our foreign operations. We also may face barriers in the form of long-standing relationships between potential customers and their existing suppliers, national policies favoring domestic manufacturers and protective regulations including exchange controls, restrictions on foreign investment or the repatriation of profits or invested capital, changes in export or import restrictions and changes in the tax system or rate of taxation in countries where we do business. We cannot assure you that we will be able to successfully develop and expand our international operations and sales or that we will be able to overcome the significant obstacles and risks of our international operations. This may impair our ability to compete with battery manufacturers who are based in such foreign countries or who have long established manufacturing or distribution facilities or networks in such countries.
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.
14

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. There is significant competition for acquisition targets in the industrial battery 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. We may be unable to successfully integrate any assets, liabilities, customers, systems and management personnel we acquire into our
15

Table of Contents
operations and we may not be able to realize related revenue synergies and cost savings within expected time frames. 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.
The failure or security breach of critical computer systems could seriously affect our sales and operations.
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.
In addition, our computer systems are essential for the exchange of information both within the company and in communicating with third parties. Despite our efforts to protect the integrity of our systems and network as well as sensitive, confidential or personal data or information, our facilities and systems and those of our third-party service providers may be vulnerable to security breaches, theft, misplaced or lost data, programming and/or human errors that could potentially lead to the compromising of sensitive, confidential or personal data or information, 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.
The approval of the Brexit Referendum in the United Kingdom may have an adverse impact on our results of operations.
In a referendum vote held on June 23, 2016, the United Kingdom voted to leave the European Union. Approximately 3% of our net sales from continuing operations in fiscal 2017 came from the U.K. At this time, we are not able to predict the impact that this vote will have on the economy in Europe, including in the U.K., or on the Great Britain Pound (the “GBP”) or other European exchange rates. Weakening of economic conditions or economic uncertainties tend to harm our business, and if such conditions emerge in the U.K. or in the rest of Europe, it may have a material adverse effect on our sales. In addition, any significant weakening of the GBP to the U.S. dollar will have an adverse impact on our European revenues due to the importance of U.K. sales.
Our ability 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 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, 2017, we had $606.1 million of total consolidated debt (including capital lease obligations). 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;

16

Table of Contents

• | 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 2017, we announced the declaration of a quarterly cash dividend of $0.175 per share of common stock for quarters ended July 3, 2016, October 2, 2016, January 1, 2017 and March 31, 2017. On May 4, 2017, we announced a fiscal 2018 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 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 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.

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, 2017, 2016 and 2015, 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,"primary working capital" and "primary working capital percentage" (see definition in “Liquidity and Capital Resources” below) along with capital expenditures, in its evaluation of business segment cash flow and financial position performance.
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 the world’s largest manufacturer, marketer and distributor of industrial batteries. We also manufacture, market and distribute products such as battery chargers, power equipment, battery accessories, and outdoor cabinet enclosures. Additionally, we provide related aftermarket and customer-support services for our products. We market our products globally to over 10,000 customers in more than 100 countries through a network of distributors, independent representatives and our internal sales force.
We operate and manage our business in three geographic regions of the world—Americas, EMEA and Asia, as described below. Our business is highly decentralized with manufacturing locations throughout the world. More than half of our manufacturing capacity is located outside the United States, and approximately 50% of our net sales were generated outside the United States. The Company has three reportable business segments based on geographic regions, defined as follows:

• | Americas, which includes North and South America, with our segment headquarters in Reading, Pennsylvania, U.S.A.;

• | EMEA, which includes Europe, the Middle East and Africa, with our segment headquarters in Zug, Switzerland; and

• | Asia, which includes Asia, Australia and Oceania, with our segment headquarters in Singapore.

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 and those charges and credits that are not directly related to ongoing business segment performance. 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 capital expenditures and primary working capital levels (see definition of primary working capital in “Liquidity and Capital Resources” below). 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.

Table of Contents
Our management structure, financial reporting systems, and associated internal controls and procedures, are all consistent with our three geographic business segments. 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.

We have two primary product lines: reserve power and motive power products. Net sales classifications by product line are as follows:

• | Reserve power products are used for backup power for the continuous operation of critical applications in telecommunications systems, uninterruptible power systems, or “UPS” applications for computer and computer-controlled systems, and other specialty power applications, including medical and security systems, premium starting, lighting and ignition applications, in switchgear, electrical control systems used in electric utilities, large-scale energy storage, energy pipelines, in commercial aircraft, satellites, military aircraft, submarines, ships and tactical vehicles. Reserve power products also include thermally managed cabinets and enclosures for electronic equipment and batteries.

• | Motive power products are used to provide 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.

Current Market Conditions
Economic Climate
Recent indicators continue to suggest a mixed trend in economic activity among the different geographical regions. North America and EMEA are experiencing limited economic growth. Our Asia region continues to grow faster than any other region in which we do business, but at a slower pace than a few years ago.
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 the global economic climate changes, we anticipate that our commodity costs and foreign currency exposures may continue to fluctuate as they have in the past several years. Over the past year, on a consolidated basis, we have experienced rising commodity costs. In addition, we have experienced unfavorable movements in foreign currency exchange rates.
Customer Pricing
Our selling prices fluctuated during the past year to offset the rising cost of commodities. Approximately 30% of our revenue is currently subject to agreements that adjust pricing to a market-based index for lead. During fiscal 2017, our selling prices increased slightly, compared to the prior year.
Liquidity and Capital Resources
We believe that our financial position is strong, and we have substantial liquidity with $500 million of available cash and cash equivalents and available and undrawn credit lines of approximately $476 million at March 31, 2017 to cover short-term liquidity requirements and anticipated growth in the foreseeable future. Our $500 million senior secured revolving credit facility and $150 million senior secured incremental term loan (the “Term Loan”), comprising the “2011 Credit Facility” is committed through September 2018 as long as we continue to comply with its covenants and conditions.
Current market conditions related to our liquidity and capital resources are favorable. We believe current conditions remain favorable for the Company to have continued positive cash flow from operations that, along with available cash and cash
24

Table of Contents
equivalents and our undrawn lines of credit, will be sufficient to fund our capital expenditures, acquisitions and other investments for growth.
In fiscal 2016, we issued $300 million of 5.00% Senior Notes due 2023 (the “Notes”), with the net proceeds used primarily to fund the payment of principal and accreted interest outstanding on the senior 3.375% convertible notes due 2038 (the “Convertible Notes”) that were settled in fiscal 2016. See Note 8 to the Consolidated Financial Statements for additional details.
Subsequent to the extinguishment of the Convertible Notes, other than the Notes and the 2011 Credit Facility, we have no other significant amount of long-term debt maturing in the near future.
In fiscal 2016, we repurchased $178 million of treasury stock through open market purchases and through an accelerated share repurchase program with a major financial institution. Share repurchases had a modest positive impact on earnings per diluted share. There were no repurchases of treasury stock in fiscal 2017.
A substantial majority of the Company’s cash and investments are held by foreign subsidiaries and are considered to be indefinitely reinvested and 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.
Cost Savings Initiatives
Cost savings programs remain a continuous element of our business strategy and are directed primarily at further reductions in plant manufacturing (labor and overhead), raw material costs and our operating expenses (primarily selling, general and administrative). In order to realize cost savings benefits for a majority of these initiatives, costs are incurred either in the form of capital expenditures, funding the cash obligations of previously recorded restructuring expenses or current period expenses.
During fiscal 2013, we announced further restructuring related to improving the efficiency of our manufacturing operations in EMEA, primarily consisting of cash expenses for employee severance-related payments and non-cash expenses associated with the write-off of certain fixed assets and inventory. These actions were substantially completed in fiscal 2015 and resulted in the reduction of approximately 140 employees. Our fiscal 2015 operating results reflected the full benefit of the estimated $7.0 million of favorable annualized pre-tax earnings impact of the fiscal 2013 programs.
During fiscal 2014, we announced additional restructuring programs to improve the efficiency of our manufacturing, sales and engineering operations in EMEA including the restructuring of its manufacturing operations in Bulgaria. The restructuring of the Bulgaria operations, which was announced during the third quarter of fiscal 2014, transferred motive power and a portion of reserve power battery manufacturing to our facilities in Western Europe. These actions resulted in the reduction of approximately 500 employees upon completion during fiscal 2016. Our fiscal 2015 operating results reflected substantially all of the approximately $19.0 million of expected favorable annualized pre-tax earnings impact of the fiscal 2014 programs.
During fiscal 2016 we announced restructuring programs related to improving operational efficiencies in EMEA and the Americas. These actions were completed in fiscal 2017 resulted in the reduction of approximately 240 employees and the closure of our Cleveland, Ohio, U.S.A., manufacturing facility. Approximately $3.0 million pre-tax savings have been reflected in the fiscal 2016 results, and an additional pre-tax savings of approximately $6.0 million have been reflected in the fiscal 2017 results.
We recently initiated an operational excellence program, referred to as EnerSys Operating System or EOS, to increase the focus on cost saving programs, as well as to improve targeted business processes, using lean tools and techniques. We began this effort in January 2017 and will gradually roll out the tools and techniques globally over a period of years. EOS is a major initiative towards our efforts to improve our operating margins by a minimum of 200 basis points by the end of fiscal 2021.

Critical Accounting Policies and Estimates
Our significant accounting policies are described in Notes to 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 recognize revenue when the earnings process is complete. This occurs when risk and title transfers, collectibility is reasonably assured and pricing is fixed or determinable. Shipment terms to our battery product customers are either shipping point or destination and do not differ significantly between our business segments. Accordingly, revenue is recognized when risk and title is transferred to the customer. Amounts invoiced to customers for shipping and handling are classified as revenue. Taxes on revenue producing transactions are not included in net sales.
We recognize revenue from the service of reserve power and motive power products when the respective services are performed.
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.
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 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 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. In January 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment”, which eliminated Step 2 from the goodwill impairment test. 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.
This update is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. Consistent with our accounting policy of carrying out the annual goodwill impairment test on the first day of the fourth quarter of a fiscal year, we conducted the annual test on January 2, 2017 and were able to early adopt ASU 2017-04. For more details, see Note 5 to the Consolidated Financial Statements.

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.
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.
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.
Our annual goodwill impairment test, which we performed during the fourth quarter of fiscal 2017, resulted in an impairment charge for goodwill and trademarks of $9.3 million and $4.7 million, in our Purcell US and Purcell EMEA reporting units, respectively, as discussed in Note 5 to the Consolidated Financial Statements. The aggregate remaining carrying value as of March 31, 2017, of goodwill and other intangibles of Purcell US and Purcell EMEA, were $25.7 million and $19.3 million, respectively. The excess of fair value over carrying value for each of our other reporting units as of January 2, 2017, the annual testing date, ranged from approximately 30% to approximately 145% of carrying value.
In order to evaluate the sensitivity of the fair value calculations on the goodwill impairment test, we applied a hypothetical 10% decrease to the fair values of each reporting unit. Excluding the Purcell US and Purcell EMEA reporting units, this hypothetical 10% decrease would result in excess fair values over carrying values range from approximately 17% to approximately 120% of the carrying values. A 10% decrease in the fair value of the Purcell US and Purcell EMEA reporting units would result in additional impairment charges of $2.4 million and $3.1 million, respectively. We will continue to evaluate goodwill on an annual basis as of the beginning of our fourth fiscal quarter and whenever events or changes in circumstances, such as significant adverse changes in business climate or operating results, changes in management's business strategy or loss of a major customer, indicate that there may be a potential indicator of impairment.
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 other 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
27

Table of Contents
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.
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 reserve power batteries and for a period ranging from one to seven years for our motive power 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
We encounter risks associated with sales and the collection of the associated accounts receivable. We record a provision for accounts receivable that are considered to be uncollectible. In order to calculate the appropriate provision, management analyzes the creditworthiness of specific customers and the aging of customer balances. Management also considers general and specific industry economic conditions, industry concentration and contractual rights and obligations.
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. During fiscal 2016, we revised our mortality assumptions to incorporate the new set of improvement tables issued by the Society of Actuaries for purposes of measuring U.S. pension and other post-retirement obligations at year-end.
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 and market condition-based awards are recognized as compensation expense based on fair value at grant date over the requisite service period of the
28

Table of Contents
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 binomial lattice model or Monte Carlo Simulation. 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 2017 were $2.4 billion, a 2% increase from prior year's sales. This increase was the result of a 2% increase in organic volume and a 1% increase each from pricing and acquisitions, partially offset by a 2% decrease due to foreign currency translation impact.
Gross profit margin percentage in fiscal 2017 increased by 110 basis points to 27.5% compared to fiscal 2016, mainly due to favorable product mix combined with the benefits of restructuring programs in EMEA, along with a modest growth in organic volume and a decrease in warranty costs.
A discussion of specific fiscal 2017 versus fiscal 2016 operating results follows, including an analysis and discussion of the results of our reportable segments.

The Americas segment’s revenue increased by $56.3 million or 4.4% in fiscal 2017, as compared to fiscal 2016, primarily due a 4% increase in organic volume and a 1% increase in acquisitions, partially offset by a 1% decrease in currency translation impact.
The EMEA segment’s revenue decreased by $24.3 million or 3.1% in fiscal 2017, as compared to fiscal 2016, primarily due to a 4% decrease in currency translation impact, partially offset by a 1% increase in organic volume.
The Asia segment’s revenue increased by $18.9 million or 7.5% in fiscal 2017, as compared to fiscal 2016, primarily due to an increase from acquisitions, pricing and organic volume of approximately 6%, 2% and 2%, respectively, partially offset by a 2% decrease in currency translation impact.

Operating Expenses
Operating expenses increased $17.2 million or 4.8% in fiscal 2017 from fiscal 2016. Operating expenses, excluding the effect of foreign currency translation, increased $22.2 million or 6.4% in fiscal 2017 compared to fiscal 2016. The operating expenses in fiscal 2017 included a receipt of $1.9 million of deferred purchase consideration relating to an acquisition made in fiscal 2014. The increase in operating expenses as a percentage of sales of 40 basis points in fiscal 2017 is primarily due to payroll related expenses, acquisitions and professional fees, partially offset by the aforementioned receipt of deferred purchase consideration. In fiscal 2017, we also recorded a charge of $9.4 million in operating expenses, related to the ERP system implementation in our Americas region, including a $6.3 million write-off of previously capitalized costs during the first quarter of fiscal 2017. We determined that previously capitalized costs associated with the implementation should be written off, after reassessing our software design subsequent to encountering difficulty in the roll out at our pilot location. These costs were previously included in the construction in progress balance within property, plant and equipment, net, in the Consolidated Balance Sheet.
Restructuring and other exit charges
Included in our fiscal 2017 operating results is a $7.1 million charge consisting of restructuring and other exit charges, comprising primarily of $5.5 million in EMEA, $0.9 million in Americas and $0.7 million in Asia. Of the restructuring and exit charges in EMEA of $5.5 million, $4.3 million of restructuring charges related primarily to European manufacturing operations and $1.2 million of exit charges related to our joint venture in South Africa. In addition, cost of goods sold also includes a $2.1 million inventory adjustment charge relating to the South Africa joint venture.
South Africa exit activities
During fiscal 2017, the Company recorded exit charges of $3.3 million related to the South Africa joint venture, consisting of cash charges of $2.6 million primarily relating to severance and non-cash charges of $0.7 million. Included in the non-cash charges is a $2.1 million charge relating to the inventory adjustment which is reported in cost of goods sold, partially offset by a credit of $1.1 million relating to a change in estimate of contract losses and a $0.3 million gain on deconsolidation of the joint venture. Weakening of the general economic environment in South Africa, reflecting the limited growth in the mining industry, affected the joint venture’s ability to compete effectively in the marketplace and consequently, the Company initiated an exit plan in consultation with its joint venture partner in the second quarter of fiscal 2017. The joint venture is currently under liquidation resulting in a loss of control and deconsolidation of the joint venture. The impact of the deconsolidation has been reflected in the Consolidated Statements of Income.
Included in fiscal 2016 operating results are restructuring and other exit charges in EMEA of $9.4 million and restructuring charges of $2.1 million and $1.4 million in Americas and Asia, respectively.
Impairment of goodwill, indefinite-lived intangibles and fixed assets
In the fourth quarter of fiscal 2017, we conducted step one of the annual goodwill impairment test which indicated that the fair values of two of our reporting units - Purcell US in the Americas and Purcell EMEA in the EMEA operating segment, were less than their respective carrying values. Based on the guidance in ASU 2017-04, which we early adopted, we recognized an impairment charge for the amount by which the carrying amount exceeded the reporting unit’s fair value.

We recorded a non-cash charge of $8.6 million and $3.6 million, related to goodwill impairment in the Americas and EMEA operating segments, respectively, and $0.7 million and $1.1 million, related to impairment of indefinite-lived trademarks in the Americas and EMEA operating segments, respectively, for an aggregate charge of $14.0 million, under the caption “Impairment of goodwill, indefinite-lived intangibles and fixed assets” in the Consolidated Statements of Income.
Purcell was acquired in fiscal 2014 during the height of the 4G telecom build-out. After performing to expectation for the first few quarters, its revenue slumped as telecom spending in the U.S. curtailed sharply. In both fiscal 2015 and 2016, lower estimated projected revenue and profitability in the near term caused by reduced levels of capital spending by major customers in the telecommunications industry was a key factor contributing to the impairment charges recorded in those years. In fiscal 2017, we transferred the European operations of Purcell to its EMEA operating segment, consistent with our geographical management approach. In the U.S., Purcell recently received significant orders, but at lower margins than recent years, resulting in an impairment in 2017. In Europe, Purcell's sales forecasts were reduced as a result of low telecom spending and accordingly recorded an impairment charge as well.
Legal proceedings charge / (reversal of legal accrual, net of fees)
Certain of our European subsidiaries have received subpoenas and requests for documents and, in some cases, interviews from, and have had on-site inspections conducted by the competition authorities of Belgium, Germany and the Netherlands relating to conduct and anticompetitive practices of certain industrial battery participants. We are responding to inquiries related to these matters. We settled the Belgian regulatory proceeding in February 2016 by acknowledging certain anticompetitive practices and conduct and agreeing to pay a fine of $2.0 million, which was paid in March 2016. As of March 31, 2017 and March 31, 2016, we had a reserve balance of $1.8 million and $2.0 million, respectively, relating to the Belgian regulatory proceeding. The change in the reserve balance between March 31, 2017 and March 31, 2016 was solely due to foreign currency translation impact. As of January 1, 2017, we had estimated an aggregate range of possible loss associated with the German regulatory proceeding of $17.0 million to $26.0 million and reserved $17.0 million with respect to the German regulatory proceeding. Based on the continued evolution of facts and our interactions with the German competition authority in regard to this matter, we further refined our estimate for a portion of this proceeding to be $13.5 million as of March 31, 2017. We do not believe that an estimate can be made at this time given the current stage of the remaining portion of this proceeding. For the Dutch regulatory proceeding, we reserved $10.3 million as of March 31, 2017. As of March 31, 2017 and March 31, 2016, we had a total reserve balance of $25.6 million and $2.0 million, respectively, in connection with these remaining investigations and other related legal matters, included in Accrued Expenses on the Consolidated Balance Sheets. The foregoing estimate of losses is based upon currently available information for these proceedings. However, the precise scope, timing and time period at issue, as well as the final outcome of the investigations or customer claims, remain uncertain. Accordingly, the Company’s estimate may change from time to time, and actual losses could vary.
Included in our fiscal 2016 results is the reversal of a $0.8 million legal accrual in Americas, relating to legal fees, subsequent to the final settlement of the Altergy matter.

(1) | The percentages shown for the segments are computed as a percentage of the applicable segment’s net sales.

Fiscal 2017 operating earnings of $235.9 million were $25.9 million higher than in fiscal 2016 and were 10.0% of sales. The 90 basis point improvement in operating margin is primarily attributable to improved mix, better manufacturing capacity utilization from higher organic volume, benefits from cost saving initiatives and lower warranty costs. Commodity costs remained relatively flat compared to the prior year but are on the rise as we exit the fiscal year. The lower restructuring and exit charges and impairment charges in fiscal 2017 were largely offset by the legal proceedings charge in EMEA. Also included in the operating earnings of fiscal 2016 was the $3.4 million gain on sale of our plant in Chaozhou, the People’s Republic of China (“PRC”), recorded in fiscal 2016.
The Americas segment’s operating earnings, excluding the highlighted items discussed above, increased $8.8 million or 4.8% in fiscal 2017 compared to fiscal 2016, with the operating margin increasing 10 basis points to 14.4%. This relatively flat operating margin in our Americas segment is primarily due to higher organic volume, improved product mix in both product lines, combined with lower manufacturing costs, negatively offset by the write-off during the first quarter fiscal 2017 of previously capitalized costs of $6.3 million related to the new ERP system.
The EMEA segment’s operating earnings, excluding the highlighted items discussed above, increased $0.6 million or 1.0% in fiscal 2017 compared to fiscal 2016, with the operating margin increasing 40 basis points to10.0%. This increase is primarily on account of improved product mix, manufacturing efficiencies and lower warranty costs combined with benefits from cost reduction programs, partially offset by currency headwinds and weak reserve power telecom market demand.
Operating earnings in Asia, excluding the highlighted items discussed above, increased $14.4 million in fiscal 2017 compared to fiscal 2016, with the operating margin increasing by 530 basis points to 5.5% is primarily due to improved product mix and results from our India operations. Our PRC operations improved as the transition from our Jiangsu to Yangzhou facilities was completed.

For both fiscal 2017 and fiscal 2016 the difference in the foreign effective tax rate versus the U.S. statutory rate of 35% is primarily attributable to lower tax rates in the foreign countries in which we operate. The rate decrease in fiscal 2017 compared to fiscal 2016 is primarily due to changes in the mix of earnings among tax jurisdictions and a decrease in non-deductible goodwill impairment charges compared to fiscal 2016, partially offset by an increase in non-deductible legal proceedings charge relating to the European competition investigation in fiscal 2017 compared to fiscal 2016.
Income from our Swiss subsidiary comprised a substantial portion of our overall foreign mix of income for both fiscal 2017 and fiscal 2016 and is taxed at approximately 5% and 7%, respectively.

Overview
Our sales in fiscal 2016 were $2.3 billion, an 8% decrease from prior year's sales. This was the result of a 7% decrease due to foreign currency translation impact and a 2% decrease in organic volume, partially offset by a 1% increase from acquisitions.
Gross margin percentage in fiscal 2016 increased by 80 basis points to 26.4% compared to fiscal 2015, mainly due to lower commodity costs and favorable product mix combined with the benefits of restructuring programs in EMEA, despite a small decline in organic volume and an increase in warranty costs.

The Americas segment’s revenue decreased by $46.4 million or 3.5% in fiscal 2016, as compared to fiscal 2015, primarily due a decrease in currency translation impact and organic volume of approximately 2%, each.
The EMEA segment’s revenue decreased by $161.4 million or 17.0% in fiscal 2016, as compared to fiscal 2015, primarily due to a decrease in currency translation impact and organic volume of approximately 12% and 6%, respectively, partially offset by a 1% increase in pricing.
The Asia segment’s revenue increased by $18.5 million or 7.9% in fiscal 2016, as compared to fiscal 2015, primarily due to an increase from acquisitions and organic volume of approximately 13% and 6%, respectively, partially offset by a 10% decrease in currency translation impact and a 1% decrease due to pricing.

Gross profit, excluding the effect of foreign currency translation, decreased $0.9 million or 0.1% in fiscal 2016 compared to fiscal 2015. The 80 basis point improvement in the gross profit margin is primarily due to lower commodity costs and favorable product mix combined with the benefits of restructuring programs in EMEA, despite a small decline in organic volume and an increase in warranty costs.

Operating Expenses
Operating expenses decreased $5.7 million or 1.6% in fiscal 2016 from fiscal 2015. Operating expenses, excluding the effect of foreign currency translation, increased $16.1 million or 4.6% in fiscal 2016 compared to fiscal 2015. As a percentage of sales, operating expenses increased from 14.3% in fiscal 2015 to 15.2% in fiscal 2016 primarily due to lower sales coupled with higher implementation costs for a new ERP system in the Americas, higher bad debt, professional services, employee incentive and stock compensation and other payroll related expenses.
Restructuring and other exit charges
Included in fiscal 2016 operating results are restructuring and other exit charges in EMEA of $9.4 million and restructuring charges of $2.1 million and $1.4 million in Americas and Asia, respectively.
Included in fiscal 2015 operating results are restructuring and other exit charges in EMEA of $7.5 million and restructuring charges of $3.9 million in Asia.
Impairment of goodwill, indefinite-lived intangibles and fixed assets
In the fourth quarter of fiscal 2016, we conducted step one of our annual goodwill impairment test which indicated that the fair values of three of our reporting units - Purcell and Quallion/ABSL US in the Americas operating segment and our South Africa joint venture in the EMEA operating segment, were less than their respective carrying value, requiring us to perform step two of the goodwill impairment analysis.
Based on our analysis, the implied fair value of goodwill was lower than the carrying value of the goodwill for the Purcell and Quallion/ABSL US reporting units in the Americas operating segment and our joint venture in South Africa in the EMEA operating segment. We recorded a non-cash charge of $31.5 million related to goodwill impairment in the Americas and the EMEA operating segments. In addition, we recorded non-cash charges of $3.4 million related to impairment of indefinite-lived trademarks in the Americas and $1.4 million related to fixed assets in the EMEA operating segment. The combined charges resulted in a tax benefit of $4.2 million, for a net charge of $32.1 million.
The key factors contributing to the impairments in both fiscal years were that the reporting units in the Americas were recent acquisitions that have not performed to management's expectations. In the case of Purcell, the impairment was the result of lower estimated projected revenue and profitability in the near term caused by reduced level of capital spending by major customers in the telecommunications industry. In the case of Quallion/ABSL US, the impairment was the result of lower estimated projected revenue and profitability in the near term caused by delays, both in introducing new products and in programs serving the aerospace and defense markets. In the case of the South Africa joint venture, declining business conditions in South Africa resulted in negative cash flows.
Legal proceedings charge / (reversal of legal accrual, net of fees)
Certain of our European subsidiaries have received subpoenas and requests for documents and, in some cases, interviews from, and have had on-site inspections conducted by the competition authorities of Belgium, Germany and the Netherlands relating to conduct and anticompetitive practices of certain industrial battery participants. We are responding to inquiries related to these

matters. We settled the Belgian regulatory proceeding in February 2016 by acknowledging certain anticompetitive practices and conduct and agreeing to pay a fine of $2.0 million, which we paid in March 2016 and as of March 31, 2016, we had a reserve balance of $2.0 million in connection with these remaining investigations and other related legal charges.
Included in our fiscal 2016 results is the reversal of a $0.8 million legal accrual in Americas, relating to legal fees, subsequent to the final settlement of the Altergy matter.

(1) | The percentages shown for the segments are computed as a percentage of the applicable segment’s net sales.

Fiscal 2016 operating earnings of $210.0 million were $53.4 million lower than in fiscal 2015 and were 9.1% of sales. Fiscal 2016 operating earnings included $49.0 million in restructuring, impairment charges and legal proceedings accrual, net of reversals and a gain on sale of facility, compared to $19.1 million in fiscal 2015. Without these net charges, operating earnings were $259.0 million or 11.2% of sales in fiscal 2016 compared to $282.5 million or 11.3% of sales in fiscal 2015, which reflects a relatively stable environment for revenues, pricing and commodity costs between the two fiscal years.
The Americas segment’s operating earnings, excluding the highlighted items discussed above, increased $19.9 million or 12.3% in fiscal 2016 compared to fiscal 2015, with the operating margin increasing 200 basis points to 14.3%. This increase of operating margin in our Americas segment is primarily due to improved product mix and pricing, lower commodity costs, partially offset by higher implementation costs relating to a new ERP system.
The EMEA segment’s operating earnings, excluding the highlighted items discussed above, decreased $34.2 million or 31.1% in fiscal 2016 compared to fiscal 2015, with the operating margin decreasing 200 basis points to 9.6%. This decrease primarily reflects foreign currency headwinds and lower reserve power product sales, particularly in the emerging markets.
Operating earnings in Asia, excluding the highlighted items discussed above, decreased $9.2 million or 94.3% in fiscal 2016 compared to fiscal 2015, with the operating margin decreasing by 400 basis points to 0.2% primarily due to lower operating results of our subsidiary in India, foreign currency headwinds and reduced telecom sales.

Interest expense of $22.3 million in fiscal 2016 (net of interest income of $1.9 million) was $2.6 million higher than the $19.7 million in fiscal 2015 (net of interest income of $1.3 million). The increase in interest expense in fiscal 2016 compared to fiscal 2015 was primarily due to higher average debt outstanding, partially offset by lower accreted interest on the Convertible Notes in fiscal 2016 compared to fiscal 2015.
Our average debt outstanding (including the average amount of the Convertible Notes discount of $0.2 million) was $626.8 million in fiscal 2016, compared to our average debt outstanding (including the average amount of the Convertible Notes discount of $5.6 million) of $422.5 million in fiscal 2015. Our average cash interest rate incurred in fiscal 2016 was 3.1% compared to 2.3% in fiscal 2015. This higher average debt outstanding is the result of our stock buy back program under which $178 million of our shares were purchased during fiscal 2016.
Included in interest expense was non-cash, accreted interest on the Convertible Notes of $1.3 million in fiscal 2016 and $8.3 million in fiscal 2015. Also included in interest expense were non-cash charges related to amortization of deferred financing fees of $1.5 million in fiscal 2016 and $1.3 million in fiscal 2015.

Other (income) expense, net was expense of $5.7 million in fiscal 2016 compared to income of $5.6 million in fiscal 2015. The unfavorable impact in fiscal 2016 is mainly attributable to foreign currency losses of $5.4 million in fiscal 2016 compared to foreign currency gains in fiscal 2015 of $5.0 million.

The Company’s income tax provisions consist of federal, state and foreign income taxes. The effective income tax rate was 27.5% in fiscal 2016 compared to the fiscal 2015 effective income tax rate of 27.2%. The rate increase in fiscal 2016 as compared to fiscal 2015 is primarily due to changes in the mix of earnings among tax jurisdictions. The fiscal 2016 effective income tax rate also includes an increase due to a larger non-deductible goodwill impairment charge as compared to fiscal 2015.
The fiscal 2016 foreign effective income tax rate on foreign pre-tax income of $117.7 million was 16.9% compared to foreign pre-tax income of $173.0 million and effective income tax rate of 14.8% in fiscal 2015. For both fiscal 2016 and fiscal 2015 the difference in the foreign effective tax rate versus the U.S. statutory rate of 35% is primarily attributable to lower tax rates in the foreign countries in which we operate. The rate increase in fiscal 2016 compared to fiscal 2015 is primarily due to changes in the mix of earnings among tax jurisdictions and due to a larger non-deductible goodwill impairment charge compared to fiscal 2015.
Income from our Swiss subsidiary comprised a substantial portion of our overall foreign mix of income for both fiscal 2016 and fiscal 2015 and is taxed at approximately 7%.
Liquidity and Capital Resources
Cash Flow and Financing Activities
Cash and cash equivalents at March 31, 2017, 2016 and 2015, were $500.3 million, $397.3 million and $268.9 million, respectively.
Cash provided by operating activities for fiscal 2017, 2016 and 2015, was $246.0 million, $307.6 million and $194.5 million, respectively.
During fiscal 2017, cash provided by operating activities was primarily from net earnings of $158.2 million, depreciation and amortization of $53.9 million, non-cash charges relating to write-off of goodwill and other assets of $20.3 million, stock-based compensation of $19.2 million, provision of doubtful accounts of $1.8 million, restructuring and other exit charges of $1.4 million, and non-cash interest of $1.4 million. Cash provided by operating activities were partially offset by the increase in primary working capital of $55.5 million, net of currency translation changes. Cash provided by operating activities were positively impacted by legal proceedings accrual of $23.7 million and accrued expenses of $9.3 million, comprising primarily of income and other taxes.
During fiscal 2016, cash from operating activities was provided primarily from net earnings of $131.8 million, depreciation and amortization of $56.0 million, non-cash charges relating to write-off of goodwill and other assets of $36.3 million, stock-based compensation of $19.6 million, provision of doubtful accounts of $4.7 million, restructuring of $3.8 million and non-cash interest of $2.8 million and were partially offset by a gain of $4.3 million on sale of our facility in the PRC. Also contributing to our cash provided from operating activities was the decrease in primary working capital of $55.0 million, net of currency translation changes.
During fiscal 2015, cash from operating activities was provided primarily from net earnings of $181.5 million, depreciation and amortization of $57.0 million, non-cash charges relating to write-off of goodwill and other assets of $23.9 million, deferred taxes of $31.9 million, stock-based compensation of $25.3 million, non-cash interest and restructuring charges of $9.5 million and $3.3 million, respectively, and were partially offset by a non-cash gain of $2.0 million on disposition of our equity interest in Altergy and non-cash credits relating to the reversal of the remaining legal accrual of $16.2 million. Also partially offsetting our cash provided from operating activities was the increase in primary working capital of $49.9 million, net of currency translation changes and our payment of $40.0 million towards the Altergy award, pursuant to the final legal settlement of the Altergy matter and accrued income tax expense of $15.5 million.
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 for this purpose 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. Primary working capital was $624.8 million (yielding a primary working capital percentage of 24.9%) at March 31, 2017 and $593.4 million (yielding a primary working capital percentage of 24.3%) at March 31, 2016. The primary working capital percentage of 24.9% at March 31, 2017 is 60 basis points higher than that for March 31, 2016, and is 40 basis points lower than that for March 31, 2015. Primary working capital percentage increased during fiscal 2017 largely due

to higher inventory levels. The reason for the increase in inventory is partially due to rising lead costs and is broad-based across the regions. We expect inventory turns to improve during fiscal 2018 due to our Lean initiatives.
Primary Working Capital and Primary Working Capital percentages at March 31, 2017, 2016 and 2015 are computed as follows:

At March 31, |  | Trade Receivables |  | Inventory |  | Accounts Payable |  | Primary Working Capital |  | Quarter Revenue Annualized |  | Primary Working Capital (%)
|  |  |  | (in millions) |  |  |  |
2017 |  | $ | 486.6 |  |  | $ | 360.7 |  |  | $ | (222.5 | ) |  | $ | 624.8 |  |  | $ | 2,507.2 |  |  | 24.9 | %

Cash used in investing activities for fiscal 2017, 2016 and 2015 was $61.8 million, $80.9 million and $59.6 million, respectively. Capital expenditures were $50.1 million, $55.9 million and $63.6 million in fiscal 2017, 2016 and 2015, respectively. During fiscal 2017, capital spending focused primarily on continuous improvement to our equipment and facilities world-wide and the continuation of a new ERP system implementation for our Americas.
During fiscal 2017, and fiscal 2016, we had minor acquisitions resulting in a cash outflow of $12.4 million and $35.4 million, respectively. There were no acquisitions in fiscal 2015.
During fiscal 2017 financing activities used cash of $62.5 million primarily due to revolver borrowings of $262.0 million and repayments of $267.0 million, repayment of our Term Loan of $15.0 million, payment of cash dividends to our stockholders of $30.4 million, and payment of taxes related to net share settlement of equity awards of $7.4 million. Net payments on short-term debt were $4.6 million.
During fiscal 2016 financing activities used cash of $105.7 million primarily due to revolver repayments of $360.8 million, purchase of treasury stock for $178.2 million, principal payment of $172.3 million to the Convertible Notes holders, payment of cash dividends to our stockholders of $30.9 million, repayment on Term Loan of $7.5 million and debt issuance costs of $5.0 million relating to the Notes. This was partially offset by revolver borrowings of $355.8 million and the issuance of $300.0 million of the Notes. Taxes paid related to net share settlement of equity awards, net of option proceeds and related tax benefits also resulted in a net outflow of $10.9 million. Net borrowings on short-term debt were $4.2 million.
During fiscal 2015, financing activities used cash of $59.3 million primarily due to revolver borrowings and repayments of $372.7 million and $322.7 million, respectively, and $150.0 million incremental term loan borrowing under the 2011 Credit Facility, purchase of treasury stock for $205.4 million and payment of cash dividends to our stockholders of $31.7 million. Taxes paid related to net share settlement of equity awards, net of option proceeds and related tax benefits resulted in a net outflow of $8.6 million. Net repayments on short-term debt were $11.9 million.
As a result of the above, cash and cash equivalents increased $103.0 million from $397.3 million at March 31, 2016 to $500.3 million at March 31, 2017.
We currently are in compliance with all covenants and conditions under our credit agreements.
In addition to cash flows from operating activities, we had available committed and uncommitted credit lines of approximately $476 million at March 31, 2017 to cover short-term liquidity requirements. Our 2011 Credit Facility is committed through September 2018, as long as we continue to comply with the covenants and conditions of the credit facility agreement. Included in our available credit lines at March 31, 2017 is $333 million under our 2011 Credit Facility.
We believe that our cash flow from operations, available cash and cash equivalents and available borrowing capacity under our credit facilities will be sufficient to meet our liquidity needs, including normal levels of capital expenditures, for the foreseeable future; however, there can be no assurance that this will be the case.

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. Shown below are the leverage ratios at March 31, 2017 and 2016, in connection with our 2011 Credit Facility.
The total net debt as defined under our 2011 Credit Facility is $463.7 million for fiscal 2017 and is 1.4 times adjusted EBITDA (non-GAAP) as described below.
The following table provides a reconciliation of net earnings to EBITDA (non-GAAP) and adjusted EBITDA (non-GAAP) as per our 2011 Credit Facility:

(1) | We have included EBITDA (non-GAAP) and adjusted EBITDA (non-GAAP) because our lenders use them as a 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 2011 Credit Facility are based on EBITDA, subject to adjustments, which are shown above. Continued availability of credit under our 2011 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 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 $46.8 million adjustment to EBITDA in fiscal 2017 primarily related to $19.2 million of non-cash stock compensation, $1.4 million of non-cash restructuring and other exit charges and $24.1 million of impairment of goodwill, indefinite-lived intangibles, fixed assets and ERP system related charges, $2.0 million relating to minority partners' share of joint venture losses and $0.1 million of acquisition expenses. The $60.5 million adjustment to EBITDA in fiscal 2016 primarily related to $19.6 million of non-cash stock compensation, $3.8 million of non-cash restructuring and other exit charges and $36.3 million of impairment of goodwill, indefinite-lived intangibles and fixed assets and $0.7 million of acquisition expenses.

(3) | Debt includes capital lease obligations and letters of credit and is net of U.S. cash and cash equivalents and a portion of European cash investments, as defined in the 2011 Credit Facility. In fiscal 2017, the amounts deducted in the calculation of net debt were U.S. cash and cash equivalents and foreign cash investments of $150 million, respectively, and in fiscal 2016, $148 million, respectively.

(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 2011 Credit Facility.

(5) | As defined in the 2011 Credit Facility, for fiscal 2017 interest expense used in the consolidated interest coverage ratio excludes non-cash interest of $1.4 million. For fiscal 2016, interest expense used in the consolidated interest coverage ratio excludes non-cash interest of $2.8 million.

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

Market Risks
Our cash flows and earnings are subject to fluctuations resulting from changes in interest rates, foreign currency exchange rates and raw material costs. 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, 2017 are $0.5 million (pre-tax). Those contracts that result in an asset position at March 31, 2017 are $1.4 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 $3.1 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 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, 2017 |  | $46.6 |  | 45.0 |  | $1.03 |  | 8%
March 31, 2016 |  | 21.6 |  | 27.4 |  | 0.79 |  | 6
March 31, 2015 |  | 76.1 |  | 91.6 |  | 0.83 |  | 19

(1) | Based on the fiscal year lead requirements for the period then ended.

We estimate that a 10% increase in our cost of lead would have increased our annual cost of goods sold by approximately $57 million for the fiscal year ended March 31, 2017.
Foreign Currency Exchange Rate Risks
We manufacture and assemble our products globally in the Americas, EMEA and Asia. Approximately 50% of our sales and 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 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 ASC 815.
47

Table of Contents
At March 31, 2017 and 2016, we estimate that an unfavorable 10% change in the exchange rates would have decreased net unrealized gains by approximately $3.2 million and $2.9 million, respectively.

Report of Independent Registered Public Accounting Firm
The Board of Directors and Stockholders of EnerSys
We have audited the accompanying consolidated balance sheets of EnerSys as of March 31, 2017 and 2016, and 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, 2017. Our audits also included the financial statement schedule listed in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of EnerSys at March 31, 2017 and 2016, and the consolidated results of its operations and its cash flows for each of the three years in the period ended March 31, 2017, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), EnerSys’ internal control over financial reporting as of March 31, 2017, 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 30, 2017 expressed an unqualified opinion thereon.

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.
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.
In our opinion, EnerSys maintained, in all material respects, effective internal control over financial reporting as of March 31, 2017, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of EnerSys as of March 31, 2017 and 2016, and 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, 2017 of EnerSys and our report dated May 30, 2017 expressed an unqualified opinion thereon.

Notes to Consolidated Financial Statements
March 31, 2017
(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.
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.
The Company also consolidates certain subsidiaries in which the noncontrolling interest party has within its control the right to require the Company to redeem all or a portion of its interest in the subsidiary. The redeemable noncontrolling interests are reported at their estimated redemption value, and the amount presented in temporary equity is not less than the initial amount reported in temporary equity. Any adjustment to the redemption value impacts retained earnings but does not impact net income or comprehensive income. In fiscal 2017, the Company deconsolidated its joint venture in South Africa and the impact of this deconsolidation is reflected in the Consolidated Statements of Income. As a result, the Company has no redeemable noncontrolling interest on its Consolidated Balance Sheet as of March 31, 2017.
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
The Company recognizes revenue when the earnings process is complete. This occurs when risk and title transfers, collectibility is reasonably assured and pricing is fixed or determinable. Shipment terms are either shipping point or destination and do not differ significantly between the Company’s business segments. Accordingly, revenue is recognized when risk and title are transferred to the customer. Amounts invoiced to customers for shipping and handling are classified as revenue. Taxes on revenue producing transactions are not included in net sales.
The Company recognizes revenue from the service of its products when the respective services are performed.
Accruals are made at the time of sale for sales returns and other allowances based on the Company’s historical experience.
Freight Expense
Amounts billed to customers for outbound freight costs are classified as sales in the Consolidated Statements of Income. Costs incurred by the Company for outbound freight costs to customers, inbound and transfer freight are classified in cost of goods
sold.

Table of Contents
Warranties
The Company’s products are warranted for a period ranging from one to twenty years for reserve power batteries and for a period ranging from one to seven years for motive power 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.
Accounts Receivable
The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of customers to make required payments. The allowance is based on management’s estimate of uncollectible accounts, analysis of historical data and trends, as well as reviews of all relevant factors concerning the financial capability of its customers. Accounts receivable are considered to be past due based on when payments are received compared to the customer’s credit terms. Accounts are written off when management determines the account is uncollectible.
Inventories
Inventories are stated at the lower of cost or market. 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 purchase price of an acquired company is allocated between tangible and intangible assets acquired and liabilities assumed from the acquired business based on their estimated fair values, with the residual of the purchase price recorded as 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. 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.
58

Table of Contents
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.
In fiscal 2016, in accordance with guidance under ASC 350, the Company conducted the goodwill impairment test using the two-step process. In the first step, the Company compares the fair value of each reporting unit to its carrying value. 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, the Company must perform the second step of the impairment test to measure the amount of impairment loss, if any. In the second step, the reporting unit's fair value is allocated to all of the assets and liabilities of the reporting unit, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if the reporting unit was being acquired in a business combination. If the implied fair value of the reporting unit's goodwill is less than the carrying value, the difference is recorded as an impairment loss.
In fiscal 2017, as discussed in more detail under New Accounting Pronouncements, the Company early adopted ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment”, which simplified the measurement of goodwill impairment by removing the second step of the goodwill impairment test that requires a hypothetical purchase price allocation.
The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. 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.
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.
Finite-lived assets such as customer relationships, patents, and non-compete agreements are amortized over their estimated useful lives, generally over periods ranging from 3 to 20 years. The Company reviews the carrying values of these assets for possible impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable based on undiscounted estimated cash flows expected to result from its use and eventual disposition. 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.
59

Table of Contents
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.
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, 2017 and 2016.
The Company does not have any credit-related contingent features associated with its derivative instruments.

Table of Contents
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”) and 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 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 forecasts of future taxable income and available tax planning strategies that could be implemented to realize the net deferred tax assets.
The Company has not recorded United States income or foreign withholding taxes related to undistributed earnings of foreign subsidiaries because the Company currently plans to keep these amounts indefinitely invested overseas.
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
61

Table of Contents
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.
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.
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 condition-based awards
The Company grants two types of market condition-based awards - market share units and performance market share units.
The fair value of the market share units is estimated at the date of grant using a binomial lattice model with the following assumptions: a risk-free interest rate, dividend yield, time to maturity and expected volatility. These units vest and are settled in common stock on the third anniversary of the date of grant. Market share units are converted into between zero and two shares of common stock for each unit granted at the end of a three-year performance cycle. The conversion ratio is calculated by dividing the average closing share price of the Company’s common stock during the ninety calendar days immediately preceding the vesting date by the average closing share price of the Company’s common stock during the ninety calendar days immediately preceding the grant date, with the resulting quotient capped at two. This quotient is then multiplied by the number of market share units granted to yield the number of shares of common stock to be delivered on the vesting date.
The fair value of the performance market share units is estimated at the date of grant using a Monte Carlo Simulation. A participant may earn between 0% to 200% of the number of performance market share units granted, based on the total shareholder return (the“TSR”) of the Company's common stock over a three-year period. The awards will cliff vest on the third anniversary of the grant 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. Performance market share units are similar to the market share units except that the targets are more difficult to achieve and may be tied to the TSR of a defined peer group.
The Company recognizes compensation expense using the straight-line method over the life of the market share units and performance market share units except for those issued to certain retirement-eligible participants, which are expensed on an accelerated basis. The Company estimates forfeitures rather than recognizing them when they occur.
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.

Table of Contents
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, 2017, 2016 and 2015, the Company had outstanding stock options, restricted stock units, market share units and performance market share units, which could potentially dilute basic earnings per share in the future. The Convertible Notes (as defined in Note 8), prior to their extinguishment on July 17, 2015, had a dilutive impact on the EPS for the fiscal years of 2016 and 2015.
Segment Reporting
A segment for reporting purposes is based on the financial performance measures that are regularly reviewed by the chief operating decision maker to assess segment performance and to make decisions about a public entity’s allocation of resources. Based on this guidance, the Company reports its segment results based upon the three geographical regions of operations.

• | Americas, which includes North and South America, with segment headquarters in Reading, Pennsylvania, U.S.A.,

• | EMEA, which includes Europe, the Middle East and Africa, with segment headquarters in Zug, Switzerland, and

• | Asia, which includes Asia, Australia and Oceania, with segment headquarters in Singapore.

New Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” providing guidance on revenue from contracts with customers that will supersede most current revenue recognition guidance, including industry-specific guidance. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. In July 2015, the FASB voted to delay the effective date for interim and annual reporting periods beginning after December 15, 2017, with early adoption permissible one year earlier. The standard permits the use of either modified retrospective or full retrospective transition methods. The Company has developed an implementation plan, which is currently in the assessment phase. The Company has not selected a transition method and is currently evaluating the impact that adoption of the standard will have on the financial condition, results of operations and cash flows.
In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory (Topic 330).” This update requires inventory to be measured at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Subsequent measurement is unchanged for inventory measured using LIFO or the retail inventory method. This update will be effective for the Company for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The amendments in this update should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. This update will not have a material impact on the Company's consolidated financial statements.
In September 2015, the FASB issued ASU 2015-16, “Simplifying the Accounting for Measurement-Period Adjustments (Topic 805).” The amendments in this update require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments in this update require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments in this update are effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The Company adopted this standard in fiscal 2017 and this update did not have a material impact on the Company's consolidated financial statements.
In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). This update requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. The new standard requires lessors to account for leases using an approach that is substantially equivalent to
63

Table of Contents
existing guidance for sales-type leases, direct financing leases and operating leases. This update is effective for reporting periods beginning after December 15, 2018, using a modified retrospective approach, with early adoption permitted. The Company is currently assessing the potential impact that the adoption will have on its consolidated financial statements.
In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting (Topic 718)”. This update simplifies several aspects related to how share-based payments are accounted for and presented in the financial statements, including the accounting for forfeitures and tax-effects related to share-based payments at settlement, and the classification of excess tax benefits and shares surrendered for tax withholdings in the statement of cash flows. This update is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years, with early adoption permitted. The Company early adopted this standard as of April 1, 2016. The impact of the adoption of this standard was as follows:

• | approximately $1,316 of excess tax benefits was recorded through income tax expense for fiscal 2017, adopted on a prospective basis;

• | excess tax benefits were included within operating cash flows adopted on a prospective basis;

• | cash paid by the Company when directly withholding shares to satisfy an employee's statutory tax obligations continued to be classified as a financing activity; and

• | no impact on prior periods due to adopting the guidance on a prospective basis.

The Company has elected to continue its current policy of estimating forfeitures rather than recognizing forfeitures when they occur.
In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Accounting for
Goodwill Impairment”, which eliminated Step 2 from the goodwill impairment test. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be 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. In addition, income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. This update is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. ASU 2017-04 should be adopted on a prospective basis.
Consistent with the Company's accounting policy of performing the annual goodwill impairment test on the first day of the fourth quarter of a fiscal year, the Company conducted the annual goodwill impairment test on January 2, 2017 and was able to early adopt ASU 2017-04. For more details, see Note 5 to the 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. Actual results could differ from those estimates.
2. Acquisitions
There were no major acquisitions in fiscal 2017.
In fiscal 2016, the Company completed the acquisition of ICS Industries Pty. Ltd. (ICS), headquartered in Melbourne, Australia, for $34,496, net of cash acquired. ICS is a leading full line shelter designer and manufacturer with installation and maintenance services serving the telecommunications, utilities, datacenter, natural resources and transport industries operating in Australia and serving customers in the Asia Pacific region. The Company acquired tangible and intangible assets, in connection with the acquisition, including trademarks, technology, customer relationships, non-competition agreements and goodwill.

Impairment of goodwill, indefinite-lived intangibles and fixed assets
As mentioned in Note 1, Summary of Significant Accounting Policies, the Company early adopted ASU 2017-04, which eliminated Step 2 from the goodwill impairment test. In the fourth quarter of fiscal 2017, the Company conducted step one of the annual goodwill impairment test which indicated that the fair values of two of its reporting units - Purcell US in the Americas and Purcell EMEA in the EMEA operating segment - were less than their respective carrying values. Based on the guidance in ASU 2017-04, the Company recognized an impairment charge for the amount by which the carrying amount exceeded the reporting unit’s fair value.
The Company recorded a non-cash charge of $8,646 and $3,570, related to goodwill impairment in the Americas and EMEA operating segments, respectively, and $700 and $1,100 related to impairment of indefinite-lived trademarks in the Americas and
67

Table of Contents
EMEA operating segments, respectively, for an aggregate charge of $14,016, under the caption “Impairment of goodwill, indefinite-lived intangibles and fixed assets” in the Consolidated Statements of Income.
Purcell was acquired in fiscal 2014 during the height of the 4G telecom build-out. After performing to expectation for the first few quarters, its revenue slumped as telecom spending in the U.S. curtailed sharply. In both fiscal 2015 and 2016, lower estimated projected revenue and profitability in the near term caused by reduced levels of capital spending by major customers in the telecommunications industry was a key factor contributing to the impairment charges recorded in those years. In fiscal 2017, the company transferred the European operations of Purcell to its EMEA operating segment, consistent with its geographical management approach. In the U.S., Purcell recently received significant orders, but at lower margins than recent years, resulting in an impairment in 2017. In Europe, Purcell's sales forecasts were reduced as a result of low telecom spending and accordingly recorded an impairment charge as well.
In fiscal 2016, the Company recorded a non-cash charge of $31,411 related to goodwill impairment in the Americas and EMEA operating segments, $3,420 related to impairment of indefinite-lived trademarks in the Americas and $1,421 related to impairment of fixed assets in the EMEA operating segment for an aggregate charge of $36,252.
In fiscal 2015, the Company recorded a non-cash charge of $20,371 related to goodwill impairment in the Americas and EMEA operating segments and $3,575 related to impairment of indefinite-lived trademarks in the Americas for an aggregate charge of $23,946.
The Company estimated tax-deductible goodwill to be approximately $19,857 and $20,766 as of March 31, 2017 and 2016, respectively.

5.00% Senior Notes
The Company's $300,000 5.00% Senior Notes due 2023 (the “Notes”) bear interest at a rate of 5.00%. Interest is payable semiannually in arrears on April 30 and October 30 of each year, commencing on October 30, 2015. The Notes will mature on April 30, 2023, unless earlier redeemed or repurchased in full. The Notes are unsecured and unsubordinated obligations of the Company. The Notes are fully and unconditionally guaranteed (the “Guarantees”), jointly and severally, by each of its subsidiaries that are guarantors under the 2011 Credit Facility (the “Guarantors”). The Guarantees are unsecured and unsubordinated obligations of the Guarantors. The net proceeds from the sale of the Notes were used primarily to repay and retire in full the principal amount of the Company’s senior 3.375% convertible notes (the “Convertible Notes”), as discussed below, as well as, fund the accelerated share repurchase program discussed in Note 15.
2011 Credit Facility
The Company is party to a $500,000 senior secured revolving credit facility and a $150,000 senior secured incremental term loan (the “Term Loan”) that matures on September 30, 2018, comprising the “2011 Credit Facility”. The quarterly installments payable on the Term Loan were $1,875 beginning June 30, 2015 and $3,750 beginning June 30, 2016 with a final payment of $108,750 on September 30, 2018. The 2011 Credit Facility may be increased by an aggregate amount of $300,000 in revolving commitments and /or one or more new tranches of term loans, under certain conditions. Both the revolving loan and the Term Loan under the 2011 Credit Facility will bear interest, at the Company's option, at a rate per annum equal to either (i) the London Interbank Offered Rate (“LIBOR”) plus between 1.25% and 1.75% (currently 1.25% and based on the Company's
69

Table of Contents
consolidated net leverage ratio) or (ii) the Base Rate (which is the highest of (a) the Bank of America prime rate, and (b) the Federal Funds Effective Rate) plus between 0.25% and 0.75% (based on the Company’s consolidated net leverage ratio). Obligations under the 2011 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 credit facility, and 65% of the capital stock of certain of the Company’s foreign subsidiaries that are owned by the Company’s United States subsidiaries.
There are no prepayment penalties on loans under the 2011 Credit Facility. The Company had $165,000 revolver borrowings and $127,500 Term Loan borrowings outstanding under its 2011 Credit Facility as of March 31, 2017.
The current portion of the Term Loan of $15,000 is classified as long-term debt as the Company expects to refinance the future quarterly payments with revolver borrowings under its 2011 Credit Facility.
Senior Unsecured 3.375% Convertible Notes
The Company's 3.375% Convertible Notes, with an original face value of $172,500, were issued when the Company’s stock price was trading at $30.19 per share. On May 7, 2015, the Company filed a notice of redemption for all of the Convertible Notes with a redemption date of June 8, 2015 at a price equal to $1,000.66 per $1,000 original principal amount of Convertible Notes, which is equal to 100% of the accreted principal amount of the Convertible Notes being repurchased plus accrued and unpaid interest. Holders were permitted to convert their Convertible Notes at their option on or before June 5, 2015.
Ninety-nine percent of the Convertible Notes holders exercised their conversion rights on or before June 5, 2015, pursuant to which, on July 17, 2015, the Company paid $172,388, in aggregate, towards the principal balance including accreted interest, cash equivalent of fractional shares issued towards conversion premium and settled the conversion premium by issuing, in the aggregate, 1,889,431 shares of the Company's common stock from its treasury shares, thereby resulting in the extinguishment of all of the Convertible Notes as of that date. There was no impact to the income statement from the extinguishment as the fair value of the total settlement consideration transferred and allocated to the liability component approximated the carrying value of the Convertible Notes. The remaining consideration allocated to the equity component resulted in an adjustment to equity of $84,140.
The amount of interest cost recognized for the amortization of the discount on the liability component of the Convertible Notes was $0, $1,330 and $8,283, respectively, for the fiscal years ended March 31, 2017, 2016 and 2015.
The Company paid $20,781, $15,176 and $10,088, net of interest received, for interest during the fiscal years ended March 31, 2017, 2016 and 2015, respectively.
The Company’s financing agreements contain various covenants, which, absent prepayment in full of the indebtedness and other obligations, or the receipt of waivers, would limit the Company’s ability to conduct certain specified business transactions including incurring debt, mergers, consolidations or similar transactions, buying or selling assets out of the ordinary course of business, engaging in sale and leaseback transactions, paying dividends and certain other actions. The Company is in compliance with all such covenants.

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, accounts receivable and accounts payable approximate carrying value due to their short maturities.
The fair value of the Company’s short-term debt and borrowings under the 2011 Credit Facility (as defined in Note 8), 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 Company's Notes, with an original face value of $300,000, were issued in April 2015. The fair value of these Notes represent the trading values based upon quoted market prices and are classified as Level 2. The Notes were trading at approximately 101% and 96% of face value on March 31, 2017 and March 31, 2016, respectively.

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 goodwill 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 January 2, 2017 for fiscal 2017, indefinite-lived trademarks associated with Purcell US and Purcell EMEA were recorded at fair value on a nonrecurring basis at $4,300 and $3,900, respectively, and the remeasurement resulted in an impairment charge of $700 and $1,100, respectively. In determining the fair value of these assets, the Company used royalty rates ranging between 1.3%-2.5% based on comparable market rates, and used discount rates ranging between 15.0%-17.0%.
In connection with the annual impairment testing conducted as of December 28, 2015 for fiscal 2016, indefinite-lived trademarks associated with Purcell and Quallion/ABSL US were recorded at fair value on a nonrecurring basis at $10,000 and $990, respectively, and the remeasurement resulted in an aggregate impairment charge of $3,420. In determining the fair value of these assets, the Company used royalty rates ranging between 0.5%-2.5% based on comparable market rates, and used discount rates ranging between 16.0%-24.0%.
These charges are included under the caption "Impairment of goodwill, indefinite-lived intangibles and fixed assets" in the Consolidated Statements of Income.
12. 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 and the notional amounts at March 31, 2017 and 2016 were 45.0 million pounds and 27.4 million pounds, 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, 2017 and 2016, the Company had entered into a total of $30,751 and $18,206, respectively, of such contracts.
In the coming twelve months, the Company anticipates that $3,118 of net 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 Statement 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, 2017 and 2016, the notional amount of these contracts was $13,560 and $11,156, respectively.

The Company has approximately $1,797 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 $151,340 of foreign net operating loss carryforwards, of which $110,506 may be carried forward indefinitely and $40,834 expire between fiscal 2018 and fiscal 2034. In addition, the Company also had approximately $33,263 of state net operating loss carryforwards with expirations between fiscal 2018 and fiscal 2037.
As of March 31, 2017 and 2016, the federal valuation allowance was $1,050. As of March 31, 2017 and 2016, the valuation allowance associated with the state tax jurisdictions was $705 and $656, respectively. As of March 31, 2017 and 2016, the valuation allowance associated with certain foreign tax jurisdictions was $25,298 and $23,710, respectively. The change includes an increase of $2,001 to tax expense primarily related to net operating loss carryforwards generated in the current year that the Company believes are not more likely than not to be realized, and a decrease of $413 primarily related to currency fluctuations.
A reconciliation of income taxes at the statutory rate to the income tax provision is as follows:

|  | Fiscal year ended March 31,
|  | 2017 |  | 2016 |  | 2015
United States statutory income tax expense (at 35%) |  | $ | 74,444 |  |  | $ | 63,678 |  |  | $ | 87,269 |

The effective income tax rates for the fiscal years ended March 31, 2017, 2016 and 2015 were 25.6%, 27.5% and 27.2%, 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.
In fiscal 2017, the foreign effective income tax rate on foreign pre-tax income of $132,259 was 13.5%. In fiscal 2016, the foreign effective income tax rate on foreign pre-tax income of $117,702 was 16.9% and in fiscal 2015, the foreign effective income tax rate on foreign pre-tax income of $173,012 was 14.8%. The rate decrease in fiscal 2017 compared to fiscal 2016 is primarily due to changes in the mix of earnings among tax jurisdictions and a decrease in non-deductible goodwill impairment charges compared to fiscal 2016, partially offset by an increase in non-deductible legal proceedings charge relating to the European competition investigation in fiscal 2017 compared to fiscal 2016. The rate increase in fiscal 2016 compared to fiscal 2015 is primarily due to changes in the mix of earnings among tax jurisdictions and an increase in non-deductible goodwill impairment charges compared to fiscal 2015.
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, 2017, 2016 and 2015 and was taxed at approximately 5%, 7% and 7%, respectively.
The Company has not recorded United States income or foreign withholding taxes on approximately $960,000 and $878,225 of undistributed earnings of foreign subsidiaries for fiscal years 2017 and 2016, respectively, that could be subject to taxation if remitted to the United States because the Company currently plans to keep these amounts indefinitely invested overseas. It is not practical to calculate the income tax expense that would result upon repatriation of these earnings.
Uncertain Tax Positions
The following table summarizes activity of the total amounts of unrecognized tax benefits:

|  | Fiscal year ended March 31,
|  | 2017 |  | 2016 |  | 2015
Balance at beginning of year |  | $ | 2,375 |  |  | $ | 4,112 |  |  | $ | 3,743 |
Increases related to current year tax positions |  | 252 |  |  | 422 |  |  | 3,241 |
Increases related to prior year tax positions |  | 31 |  |  | 470 |  |  | 9 |
Decreases related to prior tax positions due to foreign currency translation |  | (352 | ) |  | — |  |  | (85 | )
Decreases related to prior year tax positions settled |  | (678 | ) |  | (2,315 | ) |  | (2,695 | )
Lapse of statute of limitations |  | (178 | ) |  | (314 | ) |  | (101 | )
Balance at end of year |  | $ | 1,450 |  |  | $ | 2,375 |  |  | $ | 4,112 |

All of the balance of unrecognized tax benefits at March 31, 2017, 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 2014.
While the net effect on total unrecognized tax benefits cannot be reasonably estimated, approximately $284 is expected to reverse in fiscal 2017 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, 2017 and 2016, the Company had an accrual of $112 and $310, respectively, for interest and penalties.

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,
|  | 2017 |  | 2016 |  | 2017 |  | 2016

Rate of compensation increase |  | N/A |  |  | N/A |  |  | 1.5-4.0 |  | 1.5-4.0

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 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.

16. Stock-Based Compensation
As of March 31, 2017, the Company maintains the Second Amended and Restated EnerSys 2010 Equity Incentive Plan (“2010 EIP”). The 2010 EIP reserved 3,177,477 shares of common stock for the grant of various classes of nonqualified stock options, restricted stock units, market share units and other forms of equity-based compensation. Shares subject to any awards that expire without being exercised or that are forfeited or settled in cash shall again be available for future grants of awards under the 2010 EIP. Shares subject to awards that have been retained by the Company in payment or satisfaction of the exercise price and any applicable tax withholding obligation of an award shall not count against the limit described above.
As of March 31, 2017, 823,554 shares are available for future grants. The Company’s management equity incentive plans are intended to provide an incentive to employees and non-employee directors of the Company to remain in the service of the Company and to increase their interest in the success of the Company in order to promote the long-term interests of the Company. The plans seek to promote the highest level of performance by providing an economic interest in the long-term performance of the Company. The Company settles employee share-based compensation awards with newly issued shares.

18. Commitments, Contingencies and Litigation
Litigation and Other Legal Matters
In the ordinary course of business, the Company and its subsidiaries are routinely defendants in or parties to many pending and threatened legal actions and proceedings, including actions brought on behalf of various classes of claimants. These actions and proceedings are generally based on alleged violations of environmental, anticompetition, employment, contract and other laws. In some of these actions and proceedings, claims for substantial monetary damages are asserted against the Company and its subsidiaries. In the ordinary course of business, the Company and its subsidiaries are also subject to regulatory and governmental examinations, information gathering requests, inquiries, investigations, and threatened legal actions and proceedings. In connection with formal and informal inquiries by federal, state, local and foreign agencies, such subsidiaries receive numerous requests, subpoenas and orders for documents, testimony and information in connection with various aspects of their activities.
European Competition Investigations
Certain of the Company’s European subsidiaries have received subpoenas and requests for documents and, in some cases, interviews from, and have had on-site inspections conducted by the competition authorities of Belgium, Germany and the Netherlands relating to conduct and anticompetitive practices of certain industrial battery participants. The Company is responding to inquiries related to these matters. The Company settled the Belgian regulatory proceeding in February 2016 by acknowledging certain anticompetitive practices and conduct and agreeing to pay a fine of $1,962, which was paid in March 2016. As of March 31, 2017 and March 31, 2016, the Company had a reserve balance of $1,830 and $2,038, respectively, relating to the Belgian regulatory proceeding. The change in the reserve balance between March 31, 2017 and March 31, 2016 was solely due to foreign currency translation impact. As of January 1, 2017, the Company had estimated an aggregate range of possible loss associated with the German regulatory proceeding of $17,000 to $26,000 and reserved $17,000 with respect to the German regulatory proceeding. Based on the continued evolution of facts and its interactions with the German competition authority in regard to this matter, the Company has further refined its estimate for a portion of this proceeding to be $13,463 as of March 31, 2017. The Company does not believe that an estimate can be made at this time given the current stage of the remaining portion of this proceeding. For the Dutch regulatory proceeding, the Company reserved $10,258 as of March 31, 2017. As of March 31, 2017 and March 31, 2016, the Company had a total reserve balance of $25,551 and $2,038, respectively, in connection with these remaining investigations and other related legal matters, included in accrued expenses on the Consolidated Balance Sheets. The foregoing estimate of losses is based upon currently available information for these proceedings. However, the precise scope, timing and time period at issue, as well as the final outcome of the investigations or

customer claims, remain uncertain. Accordingly, the Company’s estimate may change from time to time, and actual losses could vary.
Altergy
In the fourth quarter of fiscal 2014, the Company recorded a $58,184 legal proceedings charge in connection with an adverse arbitration result involving disputes between the Company's wholly-owned subsidiary, EnerSys Delaware Inc. (“EDI”), and Altergy Systems (“Altergy”). In accordance with the final term sheet, EDI paid Altergy $40,000 in settlement of this award. Altergy paid $2,000 to purchase EDI’s entire equity interest in Altergy. Since the full amount of the initial award of $58,184 was recorded in fiscal 2014, the Company reversed approximately $16,233, net of professional fees, from this previously recorded legal proceedings charge in fiscal 2015 and $799 in fiscal 2016. The Company also included the $2,000 received in exchange for its equity interest in Altergy in the Consolidated Statements of Income in Other (income) expense, net in fiscal 2015. The Company had previously written off the carrying value of the investment of $5,000 in fiscal 2014.
Environmental Issues
As a result of its operations, the Company is subject to various federal, state and local, as well as international environmental laws and regulations and is exposed to the costs and risks of registering, handling, processing, storing, transporting, and disposing of hazardous substances, especially lead and acid. The Company’s operations are also subject to federal, state, local and international occupational safety and health regulations, including laws and regulations relating to exposure to lead in the workplace.
The Company is responsible for certain cleanup obligations at the former Yuasa battery facility in Sumter, South Carolina that predates its ownership of this facility. This manufacturing facility was closed in 2001 and the Company established a reserve for this facility which was $1,123 as of March 31, 2017 and 2016. Based on current information, the Company’s management believes this reserve is adequate to satisfy the Company’s environmental liabilities at this facility. This facility is separate from the Company’s current metal fabrication facility in Sumter.
Collective Bargaining
At March 31, 2017, the Company had approximately 9,400 employees. Of these employees, approximately 29% were covered by collective bargaining agreements. Employees covered by collective bargaining agreements that did not exceed twelve months were approximately 7% of the total workforce. The average term of these agreements is 2 years, with the longest term being 3 years. The Company considers its employee relations to be good and did not experience any significant labor unrest or disruption of production during fiscal 2017.
Lead Contracts
To stabilize its costs, the Company has entered into contracts with financial institutions to fix the price of lead. The vast majority of such contracts are for a period not extending beyond one year. Under these contracts, at March 31, 2017 and 2016, the Company has hedged the price to purchase approximately 45.0 million pounds and 27.4 million pounds of lead, respectively, for a total purchase price of $46,550 and $21,628, respectively.
Foreign Currency Forward Contracts
The Company quantifies and monitors its global foreign currency exposures. On a selective basis, the Company will enter into foreign currency forward and option contracts to reduce the volatility from currency movements that affect the Company. The vast majority of such contracts are for a period not extending beyond one year. The Company’s largest exposure is from the purchase and conversion of U.S. dollar based lead costs into local currencies in EMEA. Additionally, the Company has currency exposures from intercompany financing and intercompany and third-party trade transactions. To hedge these exposures, the Company has entered into a total of $44,311 and $29,362, respectively, of foreign currency forward contracts and options with financial institutions as of March 31, 2017 and 2016, respectively.
Other
The Company has various purchase and capital commitments incident to the ordinary conduct of business. In the aggregate, such commitments are not at prices in excess of current market.
