End users of the Company's metal cutting products include manufacturers engaged in a diverse array of industries including: the manufacturers of transportation vehicles and components, machine tools and light and heavy machinery; airframe and aerospace components; and energy-related components for the oil and gas industry, as well as power generation. The Company’s wear and metallurgical powders are used by producers and suppliers in equipment-intensive operations such as road construction, mining, quarrying, and oil and gas exploration, refining, production and supply.
Unless otherwise specified, any reference to a “year” refers to our fiscal year ending on June 30. Unless the context requires otherwise, the terms “we,” “our” and “us” refer to Kennametal Inc. and its subsidiaries.
BUSINESS SEGMENT REVIEW The Company operates in two segments: Metal Cutting and Infrastructure. The Company's reportable operating segments have been determined in accordance with the Company's internal management structure, which is organized based on operating activities, the manner in which we organize segments for making operating decisions and assessing performance and the availability of separate financial results. Sales and operating income by segment are presented in Management’s Discussion and Analysis of Financial Condition and Results of Operations set forth in Item 7 of this Annual Report (MD&A). Additional segment data is provided in Note 21 of our consolidated financial statements set forth in Item 8 of this Annual Report.
METAL CUTTING The Metal Cutting segment develops and manufactures high performance tooling and metal cutting products and services and offers an assortment of standard and custom metal cutting solutions to diverse end markets, including aerospace, general engineering, energy and transportation. The products include milling, hole making, turning, threading and toolmaking systems used in the manufacture of airframes, aero engines, trucks and automobiles, ships and various types of industrial equipment. We leverage advanced manufacturing capabilities in combination with varying levels of customization to solve our customers’ toughest challenges and deliver improved productivity for a wide range of applications. Metal Cutting markets its products under the Kennametal®, WIDIA®, WIDIA Hanita® and WIDIA GTD® brands through its direct sales force, a network of independent and national distributors, integrated supplier channels and via the Internet. Application engineers and technicians are critical to the sales process and directly assist our customers with specified product design, selection, application and support.
INFRASTRUCTURE Our Infrastructure segment produces engineered tungsten carbide and ceramic components, earth-cutting tools, and advanced metallurgical powders, primarily for the energy, earthworks and general engineering end markets. These wear-resistant products include compacts, nozzles, frac seats and custom components used in oil and gas and petrochemical industries; rod blanks and abrasive water jet nozzles for general industries; earth cutting tools and systems used in underground mining, trenching and foundation drilling and road milling; tungsten carbide powders for the oil and gas, aerospace and process industries; and ceramics used by the packaging industry for metallization of films and papers. We combine deep metallurgical and engineering expertise with advanced manufacturing capabilities to deliver solutions that drive improved productivity for our customers. Infrastructure markets its products primarily under the Kennametal® brand and sells through a direct sales force as well as through distributors.
INTERNATIONAL OPERATIONS During 2021, we generated 62 percent of our consolidated sales in markets outside of the United States of America (U.S.), with principal international operations in Western Europe, China and India. We also operate manufacturing and distribution facilities in Israel, Latin America and South Africa, while serving customers through sales offices, agents and distributors in Eastern Europe and other parts of the world. While geographic diversification helps to minimize the sales and earnings effect of demand changes in any one particular region, our international operations are subject to normal risks of doing business globally, including fluctuations in currency exchange rates and changes in social, political and economic environments.

Our international assets and sales are presented in Note 21 of the Company’s consolidated financial statements, set forth in Item 8 of this Annual Report. Further information about the effects and risks of currency exchange rates are presented in the Quantitative and Qualitative Disclosures About Market Risk section, set forth in Item 7A of this Annual Report.
STRATEGY AND GENERAL DEVELOPMENT OF BUSINESS We continued to make progress on our growth and simplification/modernization initiatives in the following areas in fiscal 2021.
Growth
•Began repositioning the WIDIA product portfolio to target the Fit-for-Purpose tooling market, thereby increasing our served market by an estimated 40 percent.
•We launched 11 new product families; including KYK10 TM, our first new shapeable ceramic inserts for cast iron machining; ALUFLASH TM solid carbide endmills for aluminum and Stellite 21 AM TM powder for 3D printing.
Simplification/modernization
•Substantially completed the capital investment and restructuring from simplification/modernization, generating total savings of approximately $186 million.
•Completed six facility consolidations since fiscal 2017, delivering our footprint rationalization target.
Operational results in 2021 reflected the challenging macroeconomic environment caused by the Coronavirus Disease 2019 (COVID-19) pandemic. Sales in 2021 of $1,841.4 million decreased from $1,885.3 million in 2020, reflecting a 2 percent decrease of which 4 percent was due to organic sales decline, partially offset by 2 percent from favorable currency exchange effect.
ACQUISITIONS AND DIVESTITURES We continually evaluate new opportunities to expand existing product lines into new market areas, and to introduce new and/or complementary product offerings into new or existing areas where appropriate. In the near term, we expect to continue to grow our business and further enhance our market position through the investment opportunities that exist within our core businesses, though we may evaluate acquisition opportunities that have the potential to strengthen or expand our business.
RAW MATERIALS AND SUPPLIES Our major metallurgical raw materials consist of tungsten ore concentrates and scrap carbide, which are used to make tungsten oxide, as well as compounds and secondary materials such as cobalt. Although an adequate supply of these raw materials currently exists, our major sources for raw materials are located abroad and prices fluctuate at times. We exercise great care in selecting, purchasing and managing the availability of raw materials utilizing a mix of long-term supply agreements coupled with spot purchases. Additionally, our internal tungsten recycling capability provides us access to additional sources of tungsten, and therefore, helps to mitigate our reliance on third parties. We also purchase steel bars and forgings for making toolholders and other tool parts, as well as for producing mining tools, rotary cutting tools and accessories. We purchase products for use in manufacturing processes and for resale from thousands of suppliers located in the U.S. and abroad.
RESEARCH AND DEVELOPMENT (R&D) Our R&D efforts focus on delivering innovations to our customers from both new product and process technology development. New product development provides solutions to our customers’ manufacturing challenges and productivity requirements. New process technology is developed and implemented in-house as part of our simplification/modernization efforts to enhance product quality and efficiency at our plant sites. We use a disciplined framework, and have established “gates,” or sequential tests to remove inefficiencies and accelerate commercial success. This framework is designed to accelerate and streamline development into a series of actions and decision points, integrating resource tasks to implement new and enhanced products and process technologies faster. It is designed to ensure a strong linkage between verified customer requirements and corporate strategy, and to enable us to gain the full benefits of our investment in development work.
We hold a number of patents and trademarks which, in the aggregate, are material to the operation of our businesses. The duration of our patent protection varies throughout the world by jurisdiction.
SEASONALITY Our business is affected by seasonal variations to varying degrees by traditional summer vacation shutdowns of customers’ plants and holiday shutdowns that affect our sales levels during the first and second quarters of our fiscal year.
BACKLOG Our backlog of orders generally is not significant to our operations.

COMPETITION As one of the world’s leading producers of tooling and metal cutting products, specialty wear-resistant components and ceramics, earth cutting tools and advanced metallurgical powders, we maintain a leading competitive position in major markets worldwide. We actively compete in the sale of all our products with several large global competitors and with many smaller niche businesses offering various capabilities to customers around the world. While several of our competitors are divisions of larger corporations, our industry remains largely fragmented, containing several hundred fabricators, toolmakers and niche specialty coating businesses. Many of our competitors operate relatively small facilities, producing a limited selection of tools while buying cemented tungsten carbide components from original producers of cemented tungsten carbide products, including Kennametal. We also supply coating solutions and other engineered wear-resistant products to both larger corporations and smaller niche businesses. Given the fragmentation, opportunities for consolidation exist from both U.S.-based and internationally-based firms, as well as among thousands of industrial supply distributors.
The principal competitive differentiators in our businesses include customer focused support and application expertise, custom and standard product innovation, product performance and quality and our brand recognition. We derive competitive advantage from our premium brand positions, global presence, application expertise and ability to address unique customer needs with new and improved tools, innovative surface and wear-resistant solutions, highly engineered components, consistent quality, traditional and digital customer service and technical assistance capabilities, state-of-the-art manufacturing and multiple sales channels. With these strengths, we are able to sell products based on the value-added productivity we deliver to our customers, rather than competing solely on price.
REGULATION From time to time, we are a party to legal claims and proceedings that arise in the ordinary course of business, which may relate to our operations or assets, including real, tangible, or intellectual property assets. While we currently believe that the amount of ultimate liability, if any, we may face with respect to these actions will not materially affect our financial position, results of operations or liquidity, the ultimate outcome of any litigation is uncertain. Were an unfavorable outcome to occur or if protracted litigation were to ensue, the effect on us could be material.
Compliance with government laws and regulations pertaining to the discharge of materials or pollutants into the environment or otherwise relating to the protection of the environment did not have a material effect on our capital expenditures or competitive position for the years covered by this Annual Report, nor is such compliance expected to have a material effect on us in the future.
The operation of our business has exposed us to certain liabilities and compliance costs related to environmental matters. We are involved in various environmental cleanup and remediation activities at certain sites associated with our current or former operations.
We establish and maintain accruals for certain potential environmental obligations. At June 30, 2021 and 2020, the balances of these accruals were $14.7 million and $15.6 million, respectively. These accruals represent anticipated costs associated with the remediation of these issues and are generally not discounted.
The accruals we have established for environmental obligations represent our best current estimate of the probable and reasonably estimable costs of addressing identified environmental situations, based on our review of currently available evidence, and taking into consideration our prior experience in remediation and that of other companies, as well as public information released by the United States Environmental Protection Agency (USEPA), other governmental agencies and by the Potentially Responsible Party (PRP) groups in which we are participating. Although the accruals currently appear to be sufficient to cover these environmental obligations, there are uncertainties associated with environmental liabilities, and we can give no assurance that our estimate of any environmental liability will not increase or decrease in the future. The recorded and unrecorded liabilities for all environmental concerns could change substantially due to factors such as the nature and extent of contamination, changes in remedial requirements, technological changes, discovery of new information, the financial strength of other PRPs, the identification of new PRPs and the involvement of and direction taken by the government on these matters.
Among other environmental laws, we are subject to the Comprehensive Environmental Response Compensation and Liability Act of 1980, under which we have been identified by the USEPA or other third party as a PRP with respect to environmental remedial costs at certain sites. We have evaluated our claims and potential liability associated with these sites based upon the best information currently available to us. We believe our environmental accruals will be adequate to cover our portion of the environmental remedial costs at those sites where we have been designated a PRP, to the extent these expenses are probable and reasonably estimable.
HUMAN CAPITAL RESOURCES
Employee Profile
We employed 8,635 people at June 30, 2021, of which approximately 2,900 were located in the U.S. and 5,700 were located in other parts of the world, principally Germany, India and China. At June 30, 2021, approximately 2,200 of our employees were represented by labor unions. We consider our labor relations to be generally good.

Diversity and Inclusion
We value diversity in all forms and are fully committed to inclusion in the workplace.
In fiscal 2021, we developed a robust strategy and supporting infrastructure to elevate and advance diversity and inclusion (D&I) across our global organization and instill accountability for our performance. The enhanced D&I strategy focuses on four strategic pillars – awareness, acquisition, development and community. To drive action and accountability, each pillar is led by a senior Kennametal executive who is known as an accountability partner and is responsible for developing strategic initiatives in partnership with our People & Culture team. While the pandemic presented challenges to fully implementing the strategy in fiscal 2021, we made strides in each pillar.
Our new Global Inclusion Council, which consists of cross-functional global leaders, champions the strategic initiatives and provides guidance and support. Four regional inclusion councils covering the Americas, Asia Pacific, EMEA and India execute the strategies and provide a global perspective.
During the fiscal year, our senior leaders went through inclusive leadership training, with topics covering shared awareness, unconscious bias and accountability, to further strengthen their skillsets and underscore their commitment to D&I.

Health and Safety
Safety, including the health of our employees, is one of our core values and a priority across our global operations. We are committed to developing a world-class health and safety culture to target zero injuries and illnesses. Our health and safety strategy is designed to focus all employees on proactively identifying, mitigating and eliminating high-risk conditions that could result in a serious injury or fatality. The strategy consists of three pillars – fatality and serious injury (FSI) prevention, incident prevention, and leadership development and compliance culture.
Our recordable cases and total recordable incident rate (TRIR) decreased to 0.37 in fiscal 2021 compared to 0.42 in fiscal 2020. In fiscal 2021, we achieved a 12 percent reduction in our TRIR compared to the prior fiscal year.
A primary goal in fiscal 2021 remained keeping our employees and their families safe from COVID-19 while meeting the needs of our customers. We enforced strict and comprehensive COVID-19 protocols and processes, including:
•Social distancing;
•Face coverings;
•Enhanced disinfecting and cleaning regimens;
•Quarantining and contact tracing;
•Limited site visitors;
•Work-from-home requirement for non-essential employees; and
•Restricted travel.
In March 2021, we launched the Give 75% a Shot campaign to encourage at least 75 percent of our employees to be vaccinated voluntarily. Where we are legally allowed to do so, employees at any location that reach the 75 percent target will be provided with an incentive in the form of award points that are part of our existing reward and recognition program. These points can be redeemed for merchandise or gift certificates of an employee’s choosing. At the end of fiscal 2021, 53 percent of eligible employees self-reported that they were in some stage of the vaccination process, while six of our sites had reached the 75 percent vaccination target. We will continue our efforts to encourage employees to get vaccinated in fiscal 2022.

Employee Development and Training
For the Company to grow, our employees must grow and develop continuously. We offer learning and development opportunities for all employees. In fiscal 2021, this included training for senior, mid-level and emerging leaders in role- and function-specific skills, such as project management, process improvement and sales effectiveness. We also offered our operational employees technical training through the Kennametal Knowledge Center.
Supporting our learning and development efforts is our new OneTeam learning management system. Available in multiple languages, OneTeam offers more than 2,800 online courses in an easy-to-use interface. Our employees completed 12,890 hours of training using the system in fiscal 2021.
We also initiated a comprehensive overhaul of our development programs, with the new approach focusing on the following:
•Individual development;
•Leadership development;
•Business- and operations-focused content;
•Sales-focused content; and
•Diversity and inclusion content.
Employee Engagement
We conducted an employee engagement survey in September 2020, achieving a 70 percent response rate. Our overall average engagement score was 64, with a percent favorable result of 55 percent. The latter was down six percentage points from our prior survey in 2018. We expected a lower score this year given the level of uncertainty and changes that we were experiencing from the COVID-19 pandemic.
As a follow-up to the survey, targeted action plans were put in place focusing on one or two important team engagement goals, and we conducted three short pulse surveys during fiscal 2021 to check on progress. In June 2021, we conducted a second full employee engagement survey to gauge overall progress in employee engagement. With a response rate of 74 percent, the June survey indicated that we continue to make progress in employee engagement, with the average engagement score increasing to 66, while our percent favorable increased to 58 percent.

RISK FACTORS
This section describes material risks to our business that are currently known to us. Our business, financial condition or results of operations may be materially affected by a number of factors. Our management regularly monitors the risks inherent in our business, with input from our Enterprise Risk Management process. In addition to real time monitoring, we periodically conduct a formal enterprise-wide risk assessment to identify factors and circumstances that might present significant risk to the Company. Many of these risks are discussed throughout this report. The risks below, however, are not exhaustive. We operate in a rapidly changing environment. Other risks that we currently believe to be immaterial could become material in the future. We are also subject to legal and regulatory changes. New factors could emerge, and it is not possible to predict the outcome of all such risk factors on our business, financial condition or results of operations. The following discussion details the material risk factors and uncertainties that we believe could cause Kennametal’s actual results to differ materially from those projected in any forward-looking statements.

Global Operational Risks:
Public health threats or outbreaks of communicable diseases could have a material adverse effect on our operations and financial results. We face risks related to public health threats or outbreaks of communicable diseases. A widespread healthcare crisis, such as an outbreak of a communicable disease could adversely affect the global economy and our business, our suppliers and our customers’ ability to conduct business for an indefinite period of time. For example, the ongoing global Coronavirus Disease 2019 (COVID-19) pandemic, has negatively affected the global economy, disrupted financial markets and international trade, resulted in increased unemployment levels and significantly affected global supply chains, all of which have and are expected to continue to affect our end markets. Federal, state, and local governments have implemented various mitigation measures at various times since the pandemic began, including travel restrictions, border closings, restrictions on public gatherings, shelter-in-place restrictions and limitations on non-essential business. Some jurisdictions have relaxed these measures, while others have not or have reinstated them as COVID-19 cases surge and variants emerge. Although we are considered an essential business in most jurisdictions, some of these actions have adversely affected the ability of our employees, contractors, suppliers, customers, and other business partners to conduct business activities, and could continue to do so for an indefinite period of time. It is not possible to accurately predict with any degree of certainty the impact COVID-19 will have on our operations going forward as the situation continues to remain fluid, including, but not limited to, the pace of the continued spread of the pandemic, the severity and ultimate duration of the pandemic, including any resurgences, mutations or variants, any governmental regulations or restrictions imposed in response to such, and the ultimate efficacy and distribution speed of approved vaccines and treatments. This could have a material adverse effect on our results of operations, financial condition, and liquidity. In particular, the continued spread of COVID-19 and variants and efforts to contain the virus could:
•continue to affect customer demand across our end markets and geographical regions;
•affect our ability to conduct business in certain jurisdictions in which we operate where nationwide, regional or local lockdowns are currently implemented or may be implemented in the future;
•cause us to experience an increase in costs as a result of the emergency measures we have taken, delayed payments from customers and uncollectible accounts;
•cause delays and disruptions in our supply chain resulting in disruptions in the commencement dates of certain planned projects;
•affect the availability of qualified personnel;
•affect our ability to fund operations and maintain covenant compliance;
•affect our access to financial markets;
•affect our ability to accurately forecast; and
•cause other unpredictable events.
The global situation surrounding COVID-19 remains uncertain. The COVID-19 pandemic has negatively affected our business operations, financial results and financial position and the industries in which we operate. The extent to which the COVID-19 pandemic may affect our business, operating results, financial condition, or liquidity in the future will depend on future developments, including the duration of the outbreak, the emergence of more contagious or virulent strains of the virus, travel restrictions, business and workforce disruptions, the availability, uptake and efficacy of vaccines, and the effectiveness of actions taken to contain and treat the disease.
Downturns in the business cycle could adversely affect our sales and profitability. Our business has historically been cyclical and subject to significant effect from economic downturns. Global economic downturns coupled with global financial and credit market disruptions have had a negative effect on our sales and profitability historically. These events could contribute to weak end markets, a sharp drop in demand for our products and services and higher costs of borrowing and/or diminished credit availability. Although we believe that the long-term prospects for our business remain positive, we are unable to predict the future course of industry variables or the strength and pace or sustainability of economic development.

Our international operations pose certain risks that may adversely affect sales and earnings. We have manufacturing operations and assets located outside of the U.S., including but not limited to those in Western Europe, Brazil, Canada, China, India, Israel and South Africa. We also sell our products to customers and distributors located outside of the U.S. During the year ended June 30, 2021, 62 percent of our consolidated sales were derived from non-U.S. markets. These international operations are subject to a number of special risks, in addition to the risks of our domestic operations, including currency exchange rate fluctuations, differing protections of intellectual property, trade barriers, exchange controls, regional economic uncertainty, overlap of different tax regimens, differing (and possibly more stringent) labor regulations, labor unrest, risk of governmental expropriation, domestic and foreign customs and tariffs, current and changing regulatory environments (including, but not limited to, the risks associated with the importation and exportation of products and raw materials), risk of failure of our foreign employees to comply with both U.S. and foreign laws, including antitrust laws, trade regulations and the Foreign Corrupt Practices Act, difficulty in obtaining distribution support, difficulty in staffing and managing widespread operations, differences in the availability and terms of financing, social and political instability and unrest and risks of increased taxes and/or adverse tax consequences. Also, in some foreign jurisdictions, we may be subject to laws limiting the right and ability of entities organized or operating therein to pay dividends or remit earnings to affiliated companies unless specified conditions are met. To the extent we are unable to effectively manage our international operations and these risks, our international sales may be adversely affected, we may be subject to additional and unanticipated costs, and we may be subject to litigation or regulatory action. As a consequence, our business, financial condition and results of operations could be seriously harmed.
Additional tax expense or exposures could affect our financial condition and results of operations. We are subject to various taxes in the U.S. and numerous other jurisdictions. Our future results of operations could be adversely affected by changes in our effective tax rate as a result of a change in the mix of earnings between U.S. and non-U.S. jurisdictions or among jurisdictions with differing statutory tax rates, changes in tax laws or treaties or in their application or interpretation, changes in generally accepted accounting principles, changes in the valuation of deferred tax assets and liabilities, changes in the amount of earnings indefinitely reinvested in certain non-U.S. jurisdictions, and the results of audits and examinations of previously filed tax returns and continuing assessments of our tax exposures.
Implementation of tariffs and changes to or uncertainties related to tariffs and trade agreements could adversely affect our business. The U.S. government has imposed tariffs on certain foreign goods from a variety of countries and regions, most notably China, that it perceives as engaging in unfair trade practices, and previously raised the possibility of imposing significant, additional tariff increases or expanding the tariffs to capture other types of goods from other countries. In response, many of these foreign governments have imposed retaliatory tariffs on goods that their countries import from the U.S. Uncertainties with respect to tariffs, trade agreements or any potential trade wars could negatively affect the global economy and could affect demand for our products and could have a material adverse effect on our financial condition, results of operations and cash flows. Changes in tariffs and trade barriers could also result in adverse changes in the cost and availability of our raw materials, and our ability to manufacture globally to support global sales which could lead to increased costs that we may not be able to effectively pass on to customers, each of which could materially adversely affect our operating margins, results of operations and cash flows.
Natural disasters or other global or regional catastrophic events could disrupt our operations and adversely affect results. Despite our concerted effort to minimize risk to our production capabilities and corporate information systems and to reduce the effect of unforeseen interruptions to us through business continuity planning, we still may be exposed to interruptions due to catastrophe, natural disaster, pandemic, terrorism or acts of war, which are beyond our control. Disruptions to our facilities or systems, or to those of our key suppliers, could also interrupt operational processes and adversely affect our ability to manufacture our products and provide services and support to our customers. As a result, our business, our results of operations, financial position, cash flows and stock price could be adversely affected.
Changes in the regulatory environment, including environmental, health and safety regulations, could subject us to increased compliance and manufacturing costs, which could have a material adverse effect on our business.
Health and Safety Regulations. Certain of our products contain hard metals, including tungsten and cobalt. Hard metal dust is being studied for potential adverse health effects by organizations in several regions throughout the world, including the U.S., Europe and Japan. Future studies on the health effects of hard metals may result in our products being classified as hazardous to human health, which could lead to new regulations in countries in which we operate that may restrict or prohibit the use of, and/or exposure to, hard metal dust. New regulation of hard metals could require us to change our operations, and these changes could affect the quality of our products and materially increase our costs.

Table of Contents
Environmental Regulations. We are subject to various environmental laws, and any violation of, or our liabilities under, these laws could adversely affect us. Our operations necessitate the use and handling of hazardous materials and, as a result, we are subject to various federal, state, local and foreign laws, regulations and ordinances relating to the protection of the environment, including those governing discharges to air and water, handling and disposal practices for solid and hazardous wastes, the cleanup of contaminated sites and the maintenance of a safe workplace. These laws impose penalties, fines and other sanctions for noncompliance and liability for response costs, property damages and personal injury resulting from past and current spills, disposals or other releases of, or exposure to, hazardous materials. We could incur substantial costs as a result of noncompliance with or liability for cleanup or other costs or damages under these laws. We may be subject to more stringent environmental laws in the future. If more stringent environmental laws are enacted in the future, these laws could have a material adverse effect on our business, financial condition and results of operations.
Regulations affecting the mining and drilling industries, utilities industry or the use of fossil fuels. Some of our principal customers are mining and drilling companies that supply coal, oil, gas or other fuels as a source of energy to utility companies or for transportation. The operations of these mining and drilling companies are geographically diverse and are subject to or affected by a wide array of regulations in the jurisdictions where they operate. As a result of changes in regulations and laws relating to these industries, including, without limitation, actions to limit or reduce greenhouse gas emissions from the use of fossil fuels, our customers’ operations could be disrupted or curtailed by governmental authorities. The high cost of compliance with these regulations may also induce customers to discontinue or limit their operations and may discourage companies from developing new opportunities. As a result of these factors, demand for our mining- and drilling-related products could be substantially affected by regulations adversely affecting the mining and drilling industries or altering the fuel choices of utilities or in transportation. Our principal customers also include transportation original equipment manufacturers and tier suppliers engaged in the production of internal combustion engines. As a result of breakthrough technologies, changing consumer preferences or regulations designed to limit or reduce greenhouse gas emissions from the use of fossil fuels in transportation, demand for our products could be negatively affected.
Product liability claims could have a material adverse effect on our business. The sale of metal cutting, mining, highway construction and other tools and related products as well as engineered components and advanced materials entails an inherent risk of product liability claims. We cannot give any assurances that the coverage limits of our insurance policies will be adequate or that our policies will cover any particular loss. Insurance can be expensive, and we may not always be able to purchase insurance on commercially acceptable terms, if at all. Claims brought against us that are not covered by insurance or that result in recoveries in excess of our insurance coverage could have a material adverse effect on our business, financial condition and results of operations.
Business Strategy Risks:
Our restructuring efforts may not have the intended effects. We are implementing restructuring and other actions to reduce structural costs, improve operational efficiency and position the Company for long-term profitable growth. However, there is no assurance that these efforts, or that any other actions that we have taken or may take in the future, will be sufficient to counter any future economic or industry disruptions. We cannot provide assurance that we will not incur additional restructuring charges or impairment charges, or that we will achieve all of the anticipated benefits from the restructuring actions we have taken, are taking now, or plan to take in the future. If we are unable to effectively restructure our operations in light of evolving market conditions, it could have a material adverse effect on our business, financial condition, results of operations and cash flows
We may not be able to complete, manage or integrate acquisitions successfully. We have acquired companies in the past and we may continue to evaluate acquisition opportunities that have the potential strengthen or expand our business. We can give no assurances, however, that any acquisition opportunities will arise or if they do, that they will be consummated, or that additional financing, if needed, will be available on satisfactory terms. In addition, acquisitions involve inherent risks that the businesses acquired will not perform in accordance with our expectations. We may not be able to achieve the synergies and other benefits we expect from the integration of acquisitions as successfully or rapidly as projected, if at all. Our failure to consummate an acquisition or effectively integrate newly acquired operations could prevent us from realizing our expected strategic growth and rate of return on an acquired business and could have a material and adverse effect on our results of operations and financial condition.

Impairment of goodwill and other intangible assets with indefinite lives could result in a negative effect on our financial condition and results of operations. At June 30, 2021, goodwill and other indefinite-lived intangible assets totaled $289.4 million, or 11 percent of our total assets. Goodwill results from acquisitions, representing the excess of cost over the fair value of the net tangible and other identifiable intangible assets we have acquired. We assess at least annually whether there has been impairment in the value of our goodwill and indefinite-lived intangible asset. If future operating performance at one or more of our reporting units were to fall significantly below current levels, we could record, under current applicable accounting rules, a non-cash impairment charge for goodwill or other intangible asset impairment. Any determination requiring the impairment of a significant portion of goodwill or other intangible assets would negatively affect our financial condition and results of operations.
Our continued success depends on our ability to protect and defend our intellectual property. Our future success depends in part upon our ability to protect and defend our intellectual property. We rely principally on nondisclosure agreements and other contractual arrangements and trade secret laws and, to a lesser extent, trademark and patent laws, to protect our intellectual property. However, these measures may be inadequate to protect our intellectual property from infringement by others or prevent misappropriation of our proprietary rights. In addition, the laws of some foreign countries do not protect proprietary rights to the same extent as do U.S. laws. If one of our patents is infringed upon by a third party, we may need to devote significant time and financial resources to defend our rights with respect to such patent. We may not be successful in defending our patents. Similarly, while we do not knowingly infringe on the patents, copyrights or other intellectual property rights of others, we may be required to spend a significant amount of time and financial resources to resolve any infringement claims against us, and we may not be successful in defending our position or negotiating alternative remedies. Our inability to protect our proprietary information and enforce or defend our intellectual property rights in proceedings initiated by us or brought against us could have a material adverse effect on our business, financial condition and results of operations.
If we are unable to retain our qualified management and employees, our business may be negatively affected. Our ability to provide high quality products and services depends in part on our ability to retain our skilled personnel in the areas of management, product engineering, servicing and sales. Competition for such personnel is intense, and our competitors can be expected to attempt to hire our management and skilled employees from time to time. In addition, our restructuring activities and strategies for growth have placed, and are expected to continue to place, increased demands on our management’s skills and resources. If we are unable to retain our management team and professional personnel, our customer relationships and level of technical expertise could be negatively affected, which may materially and adversely affect our business.
Any interruption of our workforce, including interruptions due to our restructuring initiatives, unionization efforts, changes in labor relations or shortages of appropriately skilled individuals could affect our business.
We operate in a highly competitive environment. Our domestic and foreign operations are subject to significant competitive pressures. We compete directly and indirectly with other manufacturers and suppliers of metal cutting tools, engineered components and advanced materials. Some of our competitors are larger than we are and may have greater access to financial resources or be less leveraged than us. In addition, the industry in which our products are used is a large, fragmented industry that is highly competitive.
Cybersecurity Risks:
Failure of, or a breach in security of, our information technology systems could adversely affect our business. We rely on information technology infrastructure to achieve our business objectives. Any disruption of our infrastructure could negatively affect our ability to record or process orders, manufacture and ship in a timely manner, or otherwise carry on business in the normal course. Any disruption could cause us to lose customers or revenue and could require us to incur significant expense to remediate.
Increased global information technology threats, vulnerabilities, and a rise in sophisticated and targeted international computer crime pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of our data. A security breach of our information technology systems could interrupt or damage our operations or harm our reputation. In addition, we could be subject to liability if confidential information relating to customers, employees, vendors and the extended supply chain or other parties is misappropriated from our computer system. We do not believe we have been the target of a material successful cyber attack. While we have dedicated increased resources to fortify our security measures, our systems may be vulnerable to physical break-ins, computer viruses, human error, programming errors or similar disruptive problems. Therefore, we cannot assure that our system improvements will be sufficient to prevent or limit the damage from any cyber attack or network disruption.

Raw Material Risks:
Our future operating results may be affected by fluctuations in the prices and availability of raw materials. The raw materials we use for our products include tungsten ore concentrates and scrap carbide, which are used to make tungsten oxide, as well as compounds and secondary materials such as cobalt. A significant portion of our raw materials is supplied by sources outside of the U.S. The raw materials extraction industry is highly cyclical and at times pricing and supply can be volatile due to a number of factors beyond our control, including natural disasters, pandemics or public health issues, general economic and political conditions, labor costs, competition, import duties, tariffs and currency exchange rate fluctuations. This volatility can significantly affect our raw material costs. In an environment of increasing raw material prices, competitive conditions can affect how much of these price increases we can recover in the form of higher sales prices for our products. To the extent we are unable to pass on any raw material price increases to our customers, our profitability could be adversely affected. Furthermore, restrictions in the supply of tungsten, cobalt and other raw materials could adversely affect our operating results. If the prices for our raw materials increase or we are unable to secure adequate supplies of raw materials on favorable terms, our profitability could be impaired. If the prices for our raw materials decrease, we could face product pricing challenges.
Capital and Credit-Related Risks:
Restrictions contained in our revolving credit facility and other debt agreements may limit our ability to incur additional indebtedness. Our existing revolving credit facility and other debt agreements (each a “Debt Facility” and collectively, “Debt Facilities”) contain restrictive covenants, including restrictions on our ability to incur indebtedness. These restrictions could limit our ability to effectuate future acquisitions, limit our ability to pay dividends, limit our ability to make capital expenditures or restrict our financial flexibility. Our revolving credit facility contains covenants requiring us to achieve certain financial and operating results and maintain compliance with specified financial ratios. Our ability to meet the financial covenants or requirements in our revolving credit facility may be affected by events beyond our control, and we may not be able to satisfy such covenants and requirements. A breach of these covenants or our inability to comply with the financial ratios, tests or other restrictions contained in a Debt Facility could result in an event of default under one or more of our other Debt Facilities. Upon the occurrence of an event of default under a Debt Facility, and the expiration of any grace periods, the lenders could elect to declare all amounts outstanding under one or more of our other Debt Facilities, together with accrued interest, to be immediately due and payable. If this were to occur, our assets may not be sufficient to fully repay the amounts due under our Debt Facilities or our other indebtedness.

ITEM 7 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion should be read in connection with the consolidated financial statements of Kennametal Inc. and the related financial statement notes included in Item 8 of this Annual Report. Unless otherwise specified, any reference to a “year” is to our fiscal year ended June 30. Additionally, when used in this Annual Report, unless the context requires otherwise, the terms “we,” “our” and “us” refer to Kennametal Inc. and its subsidiaries.
OVERVIEW Kennametal Inc. was founded based on a tungsten carbide technology breakthrough in 1938. The Company was incorporated in Pennsylvania in 1943 as a manufacturer of tungsten carbide metal cutting tooling, and was listed on the New York Stock Exchange (NYSE) in 1967. With more than 80 years of materials expertise, the Company is a global industrial technology leader, helping customers across the aerospace, earthworks, energy, general engineering and transportation industries manufacture with precision and efficiency. This expertise includes the development and application of tungsten carbides, ceramics, super-hard materials and solutions used in metal cutting and extreme wear applications to keep customers up and running longer against conditions such as corrosion and high temperatures.
Our standard and custom product offering spans metal cutting and wear applications including turning, milling, hole making, tooling systems and services, as well as specialized wear components and metallurgical powders. End users of the Company's metal cutting products include manufacturers engaged in a diverse array of industries including: the manufacturers of transportation vehicles and components, machine tools and light and heavy machinery; airframe and aerospace components; and energy-related components for the oil and gas industry, as well as power generation. The Company’s wear and metallurgical powders are used by producers and suppliers in equipment-intensive operations such as road construction, mining, quarrying, and oil and gas exploration, refining, production and supply.
Throughout Management's Discussion and Analysis of Financial Condition and Results of Operations (the MD&A), we refer to measures used by management to evaluate performance. We also refer to a number of financial measures that are not defined under accounting principles generally accepted in the United States of America (U.S. GAAP), including organic sales growth (decline), constant currency regional sales growth (decline) and constant currency end market sales growth (decline). The explanation at the end of the MD&A provides the definition of these non-GAAP financial measures as well as details on their use and a reconciliation to the most directly comparable GAAP financial measures.
Our sales of $1,841.4 million for the year ended June 30, 2021 decreased 2 percent year-over-year, reflecting 4 percent organic sales decline and a 2 percent favorable currency exchange effect. Despite the challenging macro-economic environment due to the COVID-19 pandemic, the Company continued to have success with sequential sales improvement each quarter throughout the year.
Operating income was $102.2 million in 2021 compared to $22.3 million in the prior year. The increase in operating income was primarily due to incremental simplification/modernization benefits of $85.0 million, lower raw material costs and $40.4 million of pre-tax restructuring and related charges compared to $83.3 million in the prior year, partially offset by increased variable compensation expense, organic sales decline and associated volume-related manufacturing inefficiencies and unfavorable geographical and product mix. Operating margin in 2021 was 5.5 percent compared to 1.2 percent in the prior year. In 2021, the Metal Cutting and Infrastructure segments had operating margins of 4.0 percent and 8.6 percent, respectively.
On March 11, 2020, the World Health Organization declared the Coronavirus Disease 2019 (COVID-19) a pandemic bringing significant uncertainty in our end markets and operations. Since then, national, regional and local governments have taken steps at various times since the pandemic began to limit the spread of the virus through stay-at-home, social distancing, and various other orders and guidelines. Although some jurisdictions have relaxed these measures, others have not or have reinstated them as COVID-19 cases surge and variants emerge. The imposition of these measures has created significant operating constraints on our business. Throughout the pandemic, based on the guidance provided by the U.S. Centers for Disease Control and other relevant authorities, we have deployed safety protocols and processes to keep our employees safe while continuing to serve our customers. To date, we have not experienced a material disruption in our supply chain. The extent to which the COVID-19 pandemic may continue to affect our business, operating results or financial condition in the future will depend on future developments, including the duration of the outbreak, the emergence of more contagious or virulent strains of the virus, travel restrictions, business and workforce disruptions, the availability, update and efficacy of vaccines and the effectiveness of other actions taken to contain and treat the disease.
The Company's cost structure benefited from our simplification/modernization initiative including the FY21 Restructuring Actions which have resulted in annualized savings of $68.0 million and pre-tax charges of $82.2 million inception to date. We recorded $40.4 million of pre-tax restructuring and related charges in 2021. Total benefits from our simplification/modernization efforts, including restructuring initiatives, were approximately $85.0 million in 2021, and we achieved total savings from simplification/modernization of approximately $186.0 million since inception. At the end of fiscal 2021 we consider the capital investment and restructuring from simplification/modernization to be substantially complete.

We reported earnings per diluted share (EPS) of $0.65 for fiscal 2021. EPS for the year was unfavorably affected by restructuring and related charges of $0.40 per share, effects from the early extinguishment of debt of $0.08 per share and partial annuitization of the Canadian pension plans of $0.02 per share, partially offset by a discrete tax benefit of $0.11 per share. Loss per diluted share in the prior year of $0.07 was unfavorably affected by restructuring and related charges of $0.88 per share, goodwill and other intangible asset impairment charges of $0.33 per share and loss on divestiture of $0.06 per share, partially offset by discrete benefits from Swiss tax reform of $0.17 per share, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) of $0.08 per share and other tax matters of $0.01 per share.
We generated cash flow from operating activities of $235.7 million in 2021 compared to $223.7 million during the prior year. Capital expenditures were $127.3 million and $244.2 million during 2021 and 2020, respectively, primarily related to our simplification/modernization initiatives. The Company returned $66.7 million and $66.3 million to shareholders through dividends during 2021 and 2020, respectively.
In connection with of the Company's focus on organizational efficiency, commercial excellence and growing its metal cutting businesses, effective July 1, 2020, Kennametal combined its former Industrial and Widia business segments to form one Metal Cutting business segment. The Infrastructure segment remains unchanged. Segment results have been retrospectively restated to reflect the change in reportable segments.
For a discussion related to the results of operations, changes in financial condition and liquidity and capital resources for fiscal 2020 compared to fiscal 2019 refer to Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations in our fiscal 2020 Form 10-K, which was filed with the United States Securities and Exchange Commission on August 20, 2020.
RESULTS OF CONTINUING OPERATIONS
SALES Sales in 2021 were $1,841.4 million, a 2 percent decrease from $1,885.3 million in 2020. The decrease was primarily due to organic sales decline of 4 percent and a 2 percent favorable currency exchange effect.

GROSS PROFIT Gross profit increased $23.0 million to $552.5 million in 2021 from $529.5 million in 2020. This increase was primarily due to incremental simplification/modernization benefits, partially offset by an organic sales decline and unfavorable labor and fixed cost absorption due to lower volumes. The gross profit margin for 2021 was 30.0 percent compared to 28.1 percent in 2020.
OPERATING EXPENSE Operating expense in 2021 was $407.2 million, an increase of $18.8 million, or 4.8 percent, from $388.4 million in 2020. The increase was primarily due to higher incentive compensation expense and unfavorable currency exchange effect of approximately $8.5 million, partially offset by incremental restructuring simplification benefits.
We invested further in technology and innovation to continue delivering high quality products to our customers. Research and development expenses included in operating expense totaled $39.5 million and $38.7 million for 2021 and 2020, respectively.

RESTRUCTURING AND RELATED CHARGES AND ASSET IMPAIRMENT CHARGES
FY20 Restructuring Actions
In the June quarter of fiscal 2019, we implemented, and in fiscal 2020 substantially completed, the FY20 Restructuring Actions associated with our simplification/modernization initiative to reduce structural costs, improve operational efficiency and position us for long-term profitable growth. Total restructuring and related charges since inception of $54.8 million were recorded for this program through June 30, 2021, consisting of: $46.6 million in Metal Cutting and $8.3 million in Infrastructure.
FY21 Restructuring Actions
In the September quarter of fiscal 2020, we announced the initiation of restructuring actions in Germany associated with our simplification/modernization initiative to reduce structural costs. Subsequently, we agreed with local employee representatives to downsize our Essen, Germany operations instead of the previously proposed closure. During the fourth quarter of fiscal 2020, we also announced the acceleration of our other structural cost reduction plans. The estimated annualized savings of the FY21 Restructuring Actions are $75 million and the expected pre-tax charges are approximately $90 million. The majority of the remaining charges related to the FY21 Restructuring Actions are expected to be in the Metal Cutting segment.
Total restructuring and related charges since inception of $82.2 million were recorded for this program through June 30, 2021, consisting of: $74.5 million in Metal Cutting and $7.7 million in Infrastructure. Inception to date, we have achieved annualized savings of approximately $68.0 million.
Annual Restructuring Charges
During 2021, we recorded restructuring and related charges of $40.4 million, which consisted of $35.6 million in Metal Cutting and $4.8 million in Infrastructure. Of this amount, restructuring charges totaled $29.6 million, of which $0.5 million was related to inventory and was recorded in cost of goods sold. Restructuring-related charges of $10.8 million were recorded in cost of goods sold.
During 2020, we recorded restructuring and related charges of $83.3 million. Of this amount, restructuring charges totaled $69.2 million, of which $0.9 million was related to inventory and was recorded in cost of goods sold. Restructuring-related charges of $14.1 million were recorded in cost of goods sold.
LOSS ON DIVESTITURE During the year ended June 30, 2020, we completed the sale of certain assets of the non-core specialty alloys and metals business within the Infrastructure segment located in New Castle, Pennsylvania to Advanced Metallurgical Group N.V. for an aggregate price of $24.0 million.
The net book value of these assets at closing was $29.5 million, and the pre-tax loss on divestiture recognized during the year ended June 30, 2020 was $6.5 million. Transaction proceeds were primarily used for capital expenditures related to our simplification/modernization efforts.
AMORTIZATION OF INTANGIBLES Amortization expense was $14.0 million and $13.8 million in 2021 and 2020, respectively.
INTEREST EXPENSE Interest expense in 2021 was $46.4 million, an increase of $11.2 million, compared to $35.2 million in 2020. The increase was primarily due to the early extinguishment of the $300.0 million of 3.875 percent Senior Unsecured Notes due 2022 (the 2022 Senior Notes). See Note 11 "Long-Term Debt" in the consolidated financial statements for further details. The portion of our debt subject to variable rates of interest was less than 1 percent at June 30, 2021 and 45.7 percent at June 30, 2020 due to $500.0 million of borrowings outstanding under the Credit Agreement in the prior year. There were no borrowings outstanding under the Credit Agreement as of June 30, 2021.
OTHER INCOME, NET In 2021, other income, net was $8.9 million, a decrease of $6.0 million from $14.9 million in 2020. The decrease was primarily due to lower net periodic pension income in fiscal 2021, including the partial annuitization of our Canadian defined benefit pension plans and lower interest income.
INCOME TAXES The effective tax rate for 2021 was 9.7 percent compared to 357.5 percent for 2020. Current year items driving the year-over-year change in the tax rate include (i) tax benefits from a provision to return adjustment related to our fiscal 2020 U.S. income tax return that included an election pursuant to Global Intangible Low-Taxed Income (GILTI) tax regulations issued during the current year, and (ii) the recognition of a stranded deferred tax balance in accumulated other comprehensive loss associated with the forward starting interest rate swaps that were terminated during fiscal 2021 when the 2022 Senior Notes were extinguished. Prior year items driving the year-over-year change include: (i) the effects of higher restructuring and related charges compared to the current year, (ii) goodwill and other intangible asset impairment charges, (iii) a $14.5 million benefit for the one-time effect of Swiss tax reform and (iv) a $6.9 million tax benefit associated with the CARES Act. See Note 13 of our consolidated financial statements set forth in Item 8 of this Annual Report for a more comprehensive discussion about Swiss tax reform and the CARES Act.

Table of Contents
As of June 30, 2021, we have $26.3 million of U.S. net deferred tax assets. Within this amount is $57.0 million related to net operating loss, tax credit, and other carryforwards that can be used to offset future U.S. taxable income. Certain of these carryforwards will expire if they are not used within a specified timeframe. At this time, we consider it more likely than not that we will have sufficient U.S. taxable income in the future that will allow us to realize these net deferred tax assets. However, it is possible that some or all of these tax attributes could ultimately expire unused, especially if our end markets do not continue to recover from the COVID-19 global pandemic. Therefore, if we are unable to generate sufficient U.S. taxable income from our operations, a valuation allowance to reduce the U.S. net deferred tax assets may be required, which would materially increase income tax expense in the period in which the valuation allowance is recorded.
In 2012, we received an assessment from the Italian tax authority that denied certain tax deductions primarily related to our 2008 tax return. Attempts at negotiating a reasonable settlement with the tax authority were unsuccessful; and as a result, we decided to litigate the matter. While the outcome of the litigation is still pending, the tax authority served notice in the September quarter of fiscal 2020 requiring payment in the amount of €36.0 million. Accordingly, we requested and were granted a stay and are not currently required to make a payment in connection with this assessment. We continue to believe that the assessment is baseless and accordingly, no income tax liability has been recorded in connection with this assessment in any period. However, if the Italian tax authority were to be successful in litigation, settlement of the amount alleged by the Italian tax authority would result in an increase to income tax expense for as much as €36.0 million, or $43.0 million, of which penalties and interest is €21.0 million, or $25.0 million.
NET INCOME (LOSS) ATTRIBUTABLE TO KENNAMETAL Net income attributable to Kennametal was $54.4 million, or $0.65 earnings per diluted share (EPS) in 2021, compared to net loss attributable to Kennametal of $5.7 million, or $0.07 loss per share in 2020. The increase is a result of the factors previously discussed.
BUSINESS SEGMENT REVIEW We operate in two reportable operating segments consisting of Metal Cutting and Infrastructure. Corporate expenses that are not allocated are reported in Corporate. Segment determination is based upon internal organizational structure, the manner in which we organize segments for making operating decisions and assessing performance and the availability of separate financial results. See Note 21 of our consolidated financial statements set forth in Item 8 of this Annual Report.
Our sales and operating income by segment are as follows:

In 2021, Metal Cutting sales of $1,150.7 million decreased by $27.3 million, or 2 percent, from 2020. Aerospace end market sales declined in all regions due to a significant reduction in airplane manufacturing. Energy sales decreased primarily due to a decline in oil and gas drilling in the Americas, partially offset by strength in wind power generation in China. Sales in our general engineering end market declined in all regions except for Asia Pacific. The general engineering end market was impacted by lower manufacturing activity related to the COVID-19 pandemic. Transportation end market sales increased in the Americas and EMEA due to improving automotive manufacturing levels. On a regional basis, the sales increase in Asia Pacific was driven by the general engineering and energy end markets, partially offset by a decline in the aerospace end market. The sales decline in EMEA was primarily due to the aerospace end market, partially offset by an increase in the transportation end market. The sales decrease in the Americas was driven by declines in the aerospace, energy, and general engineering end markets, partially offset by an increase in sales in the transportation end market.
In 2021, Metal Cutting operating income was $45.9 million, a $44.9 million increase from 2020. The increase was primarily driven by incremental simplification/modernization benefits, no goodwill and other intangible asset impairment charges in the current year, lower restructuring and related charges of $38.1 million and lower raw material costs, partially offset by organic sales decline, unfavorable labor and fixed cost absorption due to lower volumes, an increase in variable compensation and unfavorable product mix.

In 2021, Infrastructure sales of $690.7 million decreased by $16.6 million, or 2 percent, from 2020. The reduction in U.S. oil and gas drilling activity drove year-over-year decline in the energy market. Earthworks end market sales were down year-over-year due to softness in the Americas underground mining and construction, partially offset by EMEA construction. In general engineering the increase in sales was driven by Asia Pacific and the Americas. On a regional basis, the sales decrease in the Americas was driven by declines in the energy and earthworks end markets, partially offset by an increase in the general engineering end market. The sales decrease in EMEA was primarily driven by a decline in general engineering, partly offset by an increase in the earthworks end market. The increase in sales in Asia Pacific was primarily driven by growth in the general engineering end market.
In 2021, Infrastructure operating income was $59.5 million, a $36.3 million increase from 2020. The primary drivers for the increase were incremental simplification/modernization benefits and lower material costs. These benefits were partially offset by increased variable compensation, an organic sales decline and unfavorable geographical and product mix.

In 2021, Corporate expense increased $1.3 million from 2020.
LIQUIDITY AND CAPITAL RESOURCES Cash flow from operations is the primary source of funding for our capital expenditures. During the year ended June 30, 2021, cash flow provided by operating activities was $235.7 million.
During fiscal 2021, we entered into the First Amendment (the Amendment) to the Fifth Amended and Restated Credit Agreement dated as of June 21, 2018, (as amended by the Amendment, the Credit Agreement). The Credit Agreement is a five-year, multi-currency, revolving credit facility and we use it to augment cash from operations and as an additional source of funds. The Credit Agreement provides for revolving credit loans of up to $700.0 million for working capital, capital expenditures and general corporate purposes. The Credit Agreement allows for borrowings in U.S. dollars, euros, Canadian dollars, pounds sterling and Japanese yen. Interest payable under the Credit Agreement is based upon the type of borrowing under the facility and may be (1) LIBOR plus an applicable margin, (2) the greater of the prime rate or the Federal Funds effective rate plus an applicable margin, or (3) fixed as negotiated by us. The Credit Agreement matures in June 2023.
The Credit Agreement requires us to comply with various restrictive and affirmative covenants, including two financial covenants: (1) a maximum leverage ratio where debt, net of domestic cash in excess of $25 million and sixty percent of the unrestricted cash held outside of the United States, must be less than or equal to 3.5 times trailing twelve months EBITDA (temporarily increased by the Amendment to 4.25 times trailing twelve months EBITDA during the period from September 30, 2020 through and including December 31, 2021), adjusted for certain non-cash expenses and which may be further adjusted, at our discretion, to include up to $120 million of cash restructuring charges through December 31, 2021; and (2) a minimum consolidated interest coverage ratio of EBITDA to interest of 3.5 times (as such terms are defined in the Credit Agreement). Borrowings under the Credit Agreement are guaranteed by our significant domestic subsidiaries.
As of June 30, 2021, we were in compliance with all covenants of the Credit Agreement and we had no borrowings outstanding and $700.0 million of availability. There were $500.0 million borrowings outstanding as of June 30, 2020.

Other lines of credit and notes payable were $8.4 million and $0.4 million at June 30, 2021 and 2020, respectively. The lines of credit represented short-term borrowings under credit lines with commercial banks in the various countries in which we operate. These credit lines, translated into U.S. dollars at June 30, 2021 exchange rates, totaled $65.0 million.
For the year ended June 30, 2021, average daily borrowings outstanding under the Credit Agreement were approximately $128.2 million. The weighted average interest rate on borrowings under the Credit Agreement was 3.1 percent for the year ended June 30, 2021.
Based upon our debt structure at June 30, 2021, less than 1 percent of our debt was exposed to variable rates of interest. At June 30, 2020, 45.7 percent of our debt was exposed to variable rates of interest due to the $500.0 million of borrowings outstanding under the Credit Agreement in the prior year.
We consider the majority of the $1.5 billion unremitted earnings of our non-U.S. subsidiaries to be permanently reinvested. With regard to these unremitted earnings, we have not, nor do we anticipate the need to, repatriate funds to the U.S. to satisfy domestic liquidity needs arising in the ordinary course of business, including liquidity needs associated with our domestic debt service requirements. Determination of the amount of unrecognized deferred tax liability related to indefinitely reinvested earnings is not practicable due to our legal entity structure and the complexity of U.S. and local tax laws. With regard to the small portion of unremitted earnings that are not indefinitely reinvested, we maintain a deferred tax liability for foreign withholding and U.S. state income taxes. The deferred tax liability associated with unremitted earnings of our non-U.S. subsidiaries not permanently reinvested is $6.4 million as of June 30, 2021.
At June 30, 2021, we had cash and cash equivalents of $154.0 million. Total Kennametal Shareholders’ equity was $1,329.6 million and total debt was $600.5 million. Our current senior credit ratings are considered investment grade. We believe that our current financial position, liquidity and credit ratings provide us access to the capital markets. We continue to closely monitor our liquidity position and the condition of the capital markets, as well as the counterparty risk of our credit providers.
The following is a summary of our contractual obligations and other commercial commitments as of June 30, 2021:

Cash Flow Provided by Operating Activities
During 2021, cash flow provided by operating activities was $235.7 million, compared to $223.7 million in 2020. During 2021, cash flow provided by operating activities consisted of net income and non-cash items amounting to $210.0 million and changes in certain assets and liabilities netting to an inflow of $25.7 million. Contributing to the changes in certain assets and liabilities were an increase in accounts payable and accrued liabilities of $46.8 million and a decrease in inventories of $61.3 million, partially offset by an increase in accounts receivable of $53.3 million, a decrease in accrued pension and postretirement benefits of $31.6 million and a decrease in accrued income taxes of $18.3 million.
During 2020, cash flow provided by operating activities was $223.7 million. Cash flow provided by operating activities consisted of net loss and non-cash items amounting to $150.3 million and changes in certain assets and liabilities netting to an inflow of $73.5 million. Contributing to the changes in certain assets and liabilities were a decrease in accounts receivable of $128.7 million and a decrease in inventories of $28.2 million, partially offset by a decrease in accounts payable and accrued liabilities of $46.3 million, a decrease in accrued pension and postretirement benefits of $20.0 million and a decrease in accrued income taxes of $8.6 million. The decreases in inventories and accounts receivable were primarily due to the decrease in demand in the March and June quarters of fiscal 2020.
Cash Flow Used for Investing Activities
Cash flow used for investing activities was $123.0 million for 2021, a decrease of $95.4 million, compared to $218.3 million in 2020. During 2021, cash flow used for investing activities included capital expenditures, net of $122.9 million, which consisted primarily of expenditures related to our simplification/modernization initiatives.
Cash flow used for investing activities was $218.3 million for 2020. During 2020, cash flow used for investing activities included capital expenditures, net of $241.5 million, which consisted primarily of expenditures related to our simplification/modernization initiatives and equipment upgrades, partially offset by proceeds from divestiture of $24.0 million from the sale of certain assets of the non-core specialty alloys and metals business located in New Castle, Pennsylvania.
Cash Flow (Used for) Provided by Financing Activities
Cash flow used for financing activities was $574.2 million for 2021, compared to cash flow provided by financing activities of $425.5 million in 2020. During the current year period, cash flow used for financing activities included $500.0 million of a net decrease in the revolving and other lines of credit, the debt refinancing (see Note 11. "Long-Term Debt" to our consolidated financial statements set forth in Part II, Item 8 of this Annual Report on Form 10-K for further discussion) and $66.7 million of cash dividends paid to Shareholders.
Cash flow provided by financing activities was $425.5 million for 2020. During 2020, cash flow provided by financing activities included an inflow of $500.4 million primarily due to borrowings outstanding under the Credit Agreement, partially offset by $66.3 million of cash dividends paid to Shareholders and $5.5 million of the effect of employee benefit and stock plans and dividend reinvestment.
FINANCIAL CONDITION At June 30, 2021, total assets were $2,665.8 million, a decrease of $371.8 million from $3,037.6 million at June 30, 2020. Total liabilities decreased $471.2 million from $1,768.8 million at June 30, 2020 to $1,297.6 million at June 30, 2021.
Working capital was $567.4 million at June 30, 2021, an increase of $24.7 million from $542.7 million at June 30, 2020. The increase in working capital was primarily driven by a decrease in revolving and other lines of credit and notes payable of $492.0 million due primarily to repayments on our Credit Agreement and an increase in accounts receivable of $65.0 million. Partially offsetting these items were a decrease in cash and cash equivalents of $452.6 million primarily due to the $500.0 million repayment under the Credit Agreement, a decrease in inventory of $46.1 million, an increase in accounts payable of $13.0 million and an increase in accrued payroll of $13.0 million. Currency exchange rate effects increased working capital by a total of approximately $26 million, the effects of which are included in the aforementioned changes.
Property, plant and equipment, net increased $16.9 million from $1,038.3 million at June 30, 2020 to $1,055.1 million at June 30, 2021, primarily due to capital additions of $127.3 million, partially offset by depreciation expense of $112.5 million, and a positive currency exchange effect of approximately $24 million.
At June 30, 2021, other assets were $605.8 million, an increase of $47.3 million from $558.5 million at June 30, 2020. The primary drivers for the increase were the increase in long-term prepaid pension benefit of $46.1 million as well as an increase in deferred income taxes by $12.0 million. These were partially offset by amortization expense of $14.0 million.

Kennametal Shareholders’ equity was $1,329.6 million at June 30, 2021, an increase of $99.7 million from $1,229.9 million in the prior year. The increase was primarily due to net income during the year of $54.4 million, capital stock issued under employee benefit and stock plans of $24.6 million and other comprehensive income. These increases were partially offset by cash dividends to Shareholders of $66.7 million.
EFFECTS OF INFLATION Despite modest inflation in recent years, rising costs, including the cost of certain raw materials, continue to affect our operations throughout the world. We strive to minimize the effects of inflation through cost containment, productivity improvements and price increases.
DISCUSSION OF CRITICAL ACCOUNTING POLICIES In preparing our consolidated financial statements in conformity with accounting principles generally accepted in the U.S., we make judgments and estimates about the amounts reflected in our consolidated financial statements. As part of our financial reporting process, our management collaborates to determine the necessary information on which to base our judgments and develops estimates used to prepare the consolidated financial statements. We use historical experience and available information to make these judgments and estimates. However, different amounts could be reported using different assumptions and in light of different facts and circumstances. Therefore, actual amounts could differ from the estimates reflected in our consolidated financial statements. Our significant accounting policies are described in Note 2 of our consolidated financial statements, which are included in Item 8 of this Annual Report. We believe that the following discussion addresses our critical accounting policies.
Revenue Recognition The Company's contracts with customers are comprised of purchase orders, and for larger customers, may also include long-term agreements. We account for a contract when it has approval and commitment from both parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable. These contracts with customers typically relate to the manufacturing of products, which represent single performance obligations that are satisfied when control of the product passes to the customer. The Company considers the timing of right to payment, transfer of risk and rewards, transfer of title, transfer of physical possession and customer acceptance when determining when control transfers to the customer. As a result, revenue is generally recognized at a point in time - either upon shipment or delivery - based on the specific shipping terms in the contract. The shipping terms vary across all businesses and depend on the product, customary local commercial terms and the type of transportation. Shipping and handling activities are accounted for as activities to fulfill a promise to transfer a product to a customer and as such, costs incurred are recorded when the related revenue is recognized. Payment for products is due within a limited time period after shipment or delivery, typically within 30 to 90 calendar days of the respective invoice dates. The Company does not generally offer extended payment terms.
Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. Amounts billed and due from our customers are classified as accounts receivable, less allowance for doubtful accounts on the consolidated balance sheets. Certain contracts with customers, primarily distributor customers, have an element of variable consideration that is estimated when revenue is recognized under the contract. Variable consideration primarily includes volume incentive rebates, which are based on achieving a certain level of purchases and other performance criteria as established by our distributor programs. These rebates are estimated based on projected sales to the customer and accrued as a reduction of net sales as they are earned. The majority of our products are consumed by our customers or end users in the manufacture of their products. Historically, we have experienced very low levels of returned products and do not consider the effect of returned products to be material. We have recorded an estimated returned goods allowance to provide for any potential returns.
We warrant that products sold are free from defects in material and workmanship under normal use and service when correctly installed, used and maintained. This warranty terminates 30 days after delivery of the product to the customer and does not apply to products that have been subjected to misuse, abuse, neglect or improper storage, handling or maintenance. Products may be returned to Kennametal only after inspection and approval by Kennametal and upon receipt by the customer of shipping instructions from Kennametal. We have included an estimated allowance for warranty returns in our returned goods allowance discussed above.
The Company records a contract asset when it has a right to payment from a customer that is conditioned on events that have occurred other than the passage of time. The Company also records a contract liability when customers prepay but the Company has not yet satisfied its performance obligation. The Company did not have any material remaining performance obligations, contract assets or liabilities as of June 30, 2021 and 2020.
The Company pays sales commissions related to certain contracts, which qualify as incremental costs of obtaining a contract. However, the Company applies the practical expedient that allows an entity to recognize incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that would have been recognized is one year or less. These costs are recorded within operating expense in our consolidated statements of income.

Stock-Based Compensation We recognize stock-based compensation expense for all stock options, restricted stock awards and restricted stock units over the period from the date of grant to the date when the award is no longer contingent on the employee providing additional service (substantive vesting period), net of expected forfeitures. We utilize the Black-Scholes valuation method to establish the fair value of all stock option awards. Time vesting stock units are valued at the market value of the stock on the grant date. Performance vesting stock units with a market condition are valued using a Monte Carlo model.
Accounting for Contingencies We accrue for contingencies when it is probable that a liability or loss has been incurred and the amount can be reasonably estimated. Contingencies by their nature relate to uncertainties that require the exercise of judgment in both assessing whether or not a liability or loss has been incurred and estimating the amount of probable loss. The significant contingencies affecting our consolidated financial statements include environmental, health and safety matters and litigation.
Long-Lived Assets We evaluate the recoverability of property, plant and equipment, operating lease right-of-use (ROU) assets and intangible assets that are amortized whenever events or changes in circumstances indicate the carrying amount of such assets may not be fully recoverable. Changes in circumstances include technological advances, changes in our business model, capital structure, economic conditions or operating performance. Our evaluation is performed at the asset group level, based upon, among other things, our assumptions about the estimated future undiscounted cash flows these assets are expected to generate. When the sum of the undiscounted cash flows is less than the carrying value, we will recognize an impairment loss to the extent that carrying value exceeds fair value. We apply our best judgment when performing these evaluations to determine if a triggering event has occurred, the undiscounted cash flows used to assess recoverability and the fair value of the asset group.
Goodwill and Indefinite-Lived Intangible Assets We evaluate the recoverability of goodwill of each of our reporting units by comparing the fair value of each reporting unit with its carrying value. The fair values of our reporting units are determined using a combination of a discounted cash flow analysis and market multiples based upon historical and projected financial information. We perform our annual impairment tests during the June quarter in connection with our annual planning process unless there are impairment indicators based on the results of an ongoing cumulative qualitative assessment that warrant a test prior to that quarter. We apply our best judgment when assessing the reasonableness of the financial projections used to determine the fair value of each reporting unit. The discounted cash flow method was used to measure the fair value of our equity under the income approach. A terminal value utilizing a constant growth rate of cash flows was used to calculate a terminal value after the explicit projection period. The estimates and assumptions used in our calculations include revenue and gross margin growth rates, expected capital expenditures to determine projected cash flows, expected tax rates and an estimated discount rate to determine present value of expected cash flows. These estimates are based on historical experiences, our projections of future operating activity and our weighted average cost of capital (WACC). In order to determine the discount rate, the Company uses a market perspective WACC approach. The WACC is calculated incorporating weighted average returns on debt and equity from market participants. Therefore, changes in the market, which are beyond the control of the Company, may have an effect on future calculations of estimated fair value.
As of June 30, 2021, there is no goodwill allocated to the Infrastructure reporting unit. As of June 30, 2021, $277.6 million of goodwill was allocated to the Metal Cutting reporting unit. We completed an annual quantitative test of goodwill impairment and determined that the fair value of the reporting unit substantially exceeded the carrying value and, therefore, no impairment was recorded during fiscal 2021.
Further, an indefinite-lived trademark intangible asset of $11.8 million in the Metal Cutting reporting unit had a fair value that approximated its carrying value as of the date of the annual impairment test and, therefore, no impairment was recorded during fiscal 2021. To determine fair value, we assumed revenue growth rates that take into effect the uncertainty related to COVID-19 in the near term, the eventual recovery of our end markets, and a residual period growth rate of 3 percent. We assumed a royalty rate of 1 percent, and the future period cash flows were discounted at 20 percent per annum.
Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the annual goodwill and indefinite-lived intangible impairment test will prove to be an accurate prediction of the future. Certain events or circumstances that could reasonably be expected to negatively affect the underlying key assumptions and ultimately affect the estimated fair values of the Metal Cutting reporting unit and of the indefinite-lived trademark may include such items as: (i) a decrease in expected future cash flows, specifically, a further decrease in sales volume driven by a prolonged weakness in customer demand or other pressures, including those related to the COVID-19 pandemic, adversely affecting our long-term sales trends and (ii) inability to achieve the sales from our strategic growth initiatives.

Pension and Other Postretirement Benefits We sponsor pension and other postretirement benefit plans for certain employees and retirees. Accounting for the cost of these plans requires the estimation of the cost of the benefits to be provided well into the future and attributing that cost over either the expected work life of employees or over average life of participants participating in these plans, depending on plan status and on participant population. This estimation requires our judgment about the discount rate used to determine these obligations, expected return on plan assets, rate of future compensation increases, rate of future health care costs, withdrawal and mortality rates and participant retirement age. Differences between our estimates and actual results may significantly affect the cost of our obligations under these plans.
In the valuation of our pension and other postretirement benefit liabilities, management utilizes various assumptions. Our discount rates are derived by identifying a theoretical settlement portfolio of high quality corporate bonds sufficient to provide for a plan’s projected benefit payments. This rate can fluctuate based on changes in the corporate bond yields. At June 30, 2021, a hypothetical 25 basis point increase or decrease in our discount rates would be immaterial to our pre-tax income.
The long-term rate of return on plan assets is estimated based on an evaluation of historical returns for each asset category held by the plans, coupled with the current and short-term mix of the investment portfolio. The historical returns are adjusted for expected future market and economic changes. This return will fluctuate based on actual market returns and other economic factors.
The rate of future health care cost increases is based on historical claims and enrollment information projected over the next fiscal year and adjusted for administrative charges. This rate is expected to decrease until 2027. At June 30, 2021, a hypothetical 1 percent increase or decrease in our health care cost trend rates would be immaterial to our pre-tax income.
Future compensation rates, withdrawal rates and participant retirement age are determined based on historical information. These assumptions are not expected to significantly change. Mortality rates are determined based on a review of published mortality tables.
We expect to contribute approximately $8 million and $1 million to our pension and other postretirement benefit plans, respectively, in 2022. Expected pension contributions in 2022 are primarily for international plans.
Allowance for Doubtful Accounts We record allowances for estimated losses resulting from the inability of our customers to make required payments. We assess the creditworthiness of our customers based on multiple sources of information and analyze additional factors such as our historical bad debt experience, industry concentrations of credit risk, current economic trends, changes in customer payment terms and forward-looking information. This assessment requires significant judgment. If the financial condition of our customers was to deteriorate, additional allowances may be required, resulting in future operating losses that are not included in the allowance for doubtful accounts at June 30, 2021.
Inventories We use the last-in, first-out method for determining the cost of a significant portion of our U.S. inventories, and they are stated at the lower of cost or market. The cost of the remainder of our inventories is measured using approximate costs determined on the first-in, first-out basis or using the average cost method, and are stated at the lower of cost or net realizable value. When market conditions indicate an excess of carrying costs over market value, a lower of cost or net realizable value provision or a lower of cost or market provision, as applicable, is recorded. Once inventory is determined to be excess or obsolete, a new cost basis is established that is not subsequently written back up in future periods.
Income Taxes Realization of our deferred tax assets is primarily dependent on future taxable income, the timing and amount of which are uncertain. A valuation allowance is recognized if it is “more likely than not” that some or all of a deferred tax asset will not be realized. As of June 30, 2021, the deferred tax assets net of valuation allowances relate primarily to net operating loss and other carryforwards, pension benefits, accrued employee benefits and inventory. In the event that we were to determine that we would not be able to realize our deferred tax assets in the future, an increase in the valuation allowance would be required. In the event we were to determine that we are able to use our deferred tax assets for which a valuation allowance is recorded, a decrease in the valuation allowance would be required.
Coronavirus Aid, Relief, and Economic Security Act (CARES Act)
On March 27, 2020, the CARES Act was enacted in response to the COVID-19 pandemic. The CARES Act, among other things, allows net operating losses arising in taxable years beginning after December 31, 2017 and before January 1, 2021 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes; permits net operating loss carryovers and carrybacks to offset 100 percent of taxable income for taxable years beginning before January 1, 2021; and modifies the limitation on business interest by increasing the allowable business interest deduction from 30 percent of adjusted taxable income to 50 percent of adjusted taxable income for taxable years beginning in 2019 or 2020. We carried back our taxable loss in the U.S. for fiscal 2020 under the provisions of the CARES Act and recorded a benefit in our tax provision during fiscal 2020.

Swiss tax reform
Legislation was effectively enacted during the December quarter of fiscal 2020 when the Canton of Schaffhausen approved the Federal Act on Tax Reform and AHV Financing on October 8, 2019 (Swiss tax reform). Significant changes from Swiss tax reform include the abolishment of certain favorable tax regimes and the creation of a multi-year transitional period at both the federal and cantonal levels.
The transitional provisions of Swiss tax reform allow companies to utilize a combination of lower tax rates and tax basis adjustments to fair value, which are used for tax depreciation and amortization purposes resulting in deductions over the transitional period. To reflect the federal and cantonal transitional provisions, as they apply to us, we recorded a deferred tax asset of $14.5 million during the December quarter of fiscal 2020. We consider the deferred tax asset from Swiss tax reform to be an estimate based on our current interpretation of the legislation, which is subject to change based on further legislative guidance, review with the Swiss federal and cantonal authorities and modifications to the underlying valuation. We anticipate finalization of the deferred tax asset within the next twelve months.
NEW ACCOUNTING STANDARDS
See Note 2 to the consolidated financial statements for information regarding recently adopted accounting pronouncements.
RECONCILIATION OF FINANCIAL MEASURES NOT DEFINED BY U.S. GAAP In accordance with SEC rules, we are providing descriptions of the non-GAAP financial measures included in this Annual Report and reconciliations to the most closely related GAAP financial measures. We believe that these measures provide useful perspective on underlying business trends and results and a supplemental measure of year-over-year results. The non-GAAP financial measures described below are used by management in making operating decisions, allocating financial resources and for business strategy purposes and may, therefore, also be useful to investors as they are a view of our business results through the eyes of management. These non-GAAP financial measures are not intended to be considered by the user in place of the related GAAP financial measure, but rather as supplemental information to our business results. These non-GAAP financial measures may not be the same as similar measures used by other companies due to possible differences in method and in the items or events being adjusted.
Organic sales growth (decline) Organic sales growth (decline) is a non-GAAP financial measure of sales growth (decline) (which is the most directly comparable GAAP measure) excluding the effects of acquisitions, divestitures, business days and foreign currency exchange from year-over-year comparisons. We believe this measure provides investors with a supplemental understanding of underlying sales trends by providing sales growth on a consistent basis. We report organic sales decline at the consolidated and segment levels.
Constant currency end market sales growth (decline) Constant currency end market sales growth (decline) is a non-GAAP financial measure of sales growth (decline) (which is the most directly comparable GAAP measure) by end market excluding the effects of acquisitions, divestitures and foreign currency exchange from year-over-year comparisons. We note that, unlike organic sales growth (decline), constant currency end market sales growth (decline) does not exclude the effect of business days. We believe this measure provides investors with a supplemental understanding of underlying end market trends by providing end market sales decline on a consistent basis. We report constant currency end market sales growth (decline) at the consolidated and segment levels.
Constant currency regional sales growth (decline) Constant currency regional sales growth (decline) is a non-GAAP financial measure of sales growth (decline) (which is the most directly comparable GAAP measure) by region excluding the effects of acquisitions, divestitures and foreign currency exchange from year-over-year comparisons. We note that, unlike organic sales growth (decline), constant currency regional sales growth (decline) does not exclude the effect of business days. We believe this measure provides investors with a supplemental understanding of underlying regional trends by providing regional sales growth (decline) on a consistent basis. We report constant currency regional sales growth (decline) at the consolidated and segment levels.

ITEM 7A - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
MARKET RISK We are exposed to certain market risks arising from transactions that are entered into in the normal course of business. As part of our financial risk management program, we use certain derivative financial instruments to manage these risks. We do not enter into derivative transactions for speculative purposes and, therefore, hold no derivative instruments for trading purposes. We may use derivative financial instruments to provide predictability to the effects of changes in foreign exchange rates on our consolidated results. Our objective in managing foreign exchange exposures with derivative instruments is to reduce volatility in cash flow, allowing us to focus more of our attention on business operations. With respect to interest rate management, we use forward-starting interest rate swaps to effectively hedge the variability in future benchmark interest payments attributable to changes in interest rates on forecasted issuances of fixed-rate debt. See Notes 2 and 17 of our consolidated financial statements set forth in Item 8 of this Annual Report.
We are exposed to counterparty credit risk for nonperformance of derivative contracts and, in the event of nonperformance, to market risk for changes in interest and currency exchange rates, as well as settlement risk. We manage exposure to counterparty credit risk through credit standards, diversification of counterparties and procedures to monitor concentrations of credit risk. We do not anticipate nonperformance by any of the counterparties.
The following provides additional information on our use of derivative instruments. Included below is a sensitivity analysis that is based upon a hypothetical 10 percent weakening or strengthening in the U.S. dollar and its effects on the June 30, 2021 currency exchange rates and the effective interest rates under our current borrowing arrangements. We compared our contractual derivative and borrowing arrangements in effect at June 30, 2021 to the hypothetical foreign exchange or interest rates in the sensitivity analysis to determine the effect on interest expense, pre-tax income and accumulated other comprehensive loss. Our analysis takes into consideration the different types of derivative instruments and the applicability of hedge accounting.
CASH FLOW HEDGES Currency A portion of our operations consists of investments in foreign subsidiaries. Our exposure to market risk from changes in foreign exchange rates arises from these investments, intercompany loans utilized to finance these subsidiaries, trade receivables and payables and firm commitments arising from international transactions. We manage our foreign exchange transaction risk to reduce the volatility of cash flows caused by currency exchange rate fluctuations through natural offsets where appropriate and through foreign exchange contracts. These contracts are designated as hedges of forecasted transactions that will settle in future periods and that would otherwise expose us to currency risk.
Our foreign exchange hedging program is intended to mitigate our exposure to currency exchange rate movements. This exposure arises largely from anticipated cash flows from cross-border intercompany sales of products and services. This program utilizes range forwards and forward contracts primarily to sell foreign currency. All outstanding range forward contracts expired as of June 30, 2021. The notional amount of the contracts translated into U.S. dollars at June 30, 2020 was $2.2 million.
Interest rate During fiscal 2020 we entered into seven forward-starting interest rate swap contracts with an aggregate notional amount totaling $200.0 million. A forward-starting interest rate swap is an agreement that effectively hedges the variability in future benchmark interest payments attributable to changes in interest rates on the forecasted issuance of fixed-rate debt. During fiscal 2021, upon issuance of the Senior Unsecured Notes due 2031 we settled the forward starting interest rate swap contracts for a gain of $10.2 million in other comprehensive income (loss). The gain will be amortized out of accumulated other comprehensive income (loss) and into interest expense (as a benefit) over the life of the Senior Unsecured Notes due 2031. The notional amount of the forward starting interest rate swap contracts at June 30, 2020 was $200.0 million. We recorded $2.1 million of liabilities as of June 30, 2020 related to these contracts. There were no interest rate swap contracts outstanding at June 30, 2021.
DEBT, REVOLVING AND OTHER LINES OF CREDIT AND NOTES PAYABLE At June 30, 2021 and 2020, we had $600.5 million and $1,094.5 million, respectively, of outstanding debt, including revolving and other lines of credit and notes payable. Effective interest rates as of June 30, 2021 and 2020 were 3.7 percent and 4.4 percent, respectively. A hypothetical change of 10 percent in market interest rates from June 30, 2021 levels would be immaterial.
CURRENCY EXCHANGE RATE FLUCTUATIONS Currency exchange rate fluctuations decreased diluted earnings per share by $0.03 in 2021 and decreased diluted earnings per share by $0.07 in 2020. Currency exchange rate fluctuations may have a material effect on future earnings in the short term and long term.

ITEM 8 - FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA
MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
Management is responsible for establishing and maintaining adequate internal control over financial reporting. Management has conducted an assessment of the Company’s internal controls over financial reporting as of June 30, 2021 using the criteria in Internal Control – Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. 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.
Based on its assessment, management has concluded that the Company maintained effective internal control over financial reporting as of June 30, 2021, based on the criteria in Internal Control – Integrated Framework (2013) issued by the COSO. The effectiveness of the Company’s internal control over financial reporting as of June 30, 2021 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included in this Annual Report on Form 10-K.

Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Kennametal Inc. and its subsidiaries (the “Company”) as of June 30, 2021 and 2020, and the related consolidated statements of income, of comprehensive income, of shareholders' equity and of cash flows for each of the three years in the period ended June 30, 2021, including the related notes and financial statement schedule listed in the index appearing under Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of June 30, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of June 30, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended June 30, 2021 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of June 30, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Assessment of the Realization of U.S. Net Deferred Tax Assets
As described in Notes 2 and 13 to the consolidated financial statements, the Company had $26.3 million of U.S. net deferred tax assets as of June 30, 2021. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not (greater than 50 percent) that a tax benefit will not be realized. In evaluating the need for a valuation allowance, management considers all potential sources of taxable income, including income available in carryback periods, future reversals of taxable temporary differences, projections of taxable income, and income from tax planning strategies, as well as available positive and negative evidence. Upon changes in facts and circumstances, management may conclude that deferred tax assets for which no valuation allowance is currently recorded may not be realized, resulting in a charge to establish a valuation allowance. If it is determined that it is more likely than not that a deferred tax asset will be realized, the appropriate amount of the valuation allowance, if any, is released.
The principal considerations for our determination that performing procedures relating to the assessment of the realization of U.S. net deferred tax assets is a critical audit matter are the significant judgment by management when determining the projections of taxable income, which in turn led to a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating audit evidence relating to management’s assessment of the realization of U.S. net deferred tax assets and management’s significant assumptions relating to projections of taxable income.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s assessment of the realization of U.S. net deferred tax assets, including controls over the determination of projections of taxable income. These procedures also included, among others (i) evaluating the positive and negative evidence available in management’s assessment of the realization of U.S. net deferred tax assets, (ii) testing the completeness and accuracy of underlying data used in management’s assessment, and (iii) evaluating the reasonableness of management’s significant assumptions related to projections of taxable income. Evaluating management’s significant assumptions related to projections of taxable income involved evaluating whether the assumptions used by management were reasonable considering (i) current and past financial performance, (ii) consistency with external market and industry data, and (iii) whether the assumptions were consistent with evidence obtained in other areas of the audit.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
NOTE 1 — NATURE OF OPERATIONS
With more than 80 years of materials expertise, the Company is a global industrial technology leader, helping customers across the aerospace, earthworks, energy, general engineering and transportation end markets manufacture with precision and efficiency. This expertise includes the development and application of tungsten carbides, ceramics, super-hard materials and solutions used in metal cutting and extreme wear applications to keep customers up and running longer against conditions such as corrosion and high temperatures.
Our standard and custom product offering spans metal cutting and wear applications including turning, milling, hole making, tooling systems and services, as well as specialized wear components and metallurgical powders. End users of the Company's metal cutting products include manufacturers engaged in a diverse array of industries including: the manufacturers of transportation vehicles and components, machine tools and light and heavy machinery; airframe and aerospace components; and energy-related components for the oil and gas industry, as well as power generation. The Company’s wear and metallurgical powders are used by producers and suppliers in equipment-intensive operations such as road construction, mining, quarrying, and oil and gas exploration, refining, production and supply.
Unless otherwise specified, any reference to a “year” is to a fiscal year ended June 30. When used in this Annual Report on Form 10-K, unless the context requires otherwise, the terms “we,” “our” and “us” refer to Kennametal Inc. and its subsidiaries.
NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
The summary of our significant accounting policies is presented below to assist in evaluating our consolidated financial statements.
PRINCIPLES OF CONSOLIDATION The consolidated financial statements include our accounts and those of our subsidiaries in which we have a controlling interest. All significant intercompany balances and transactions are eliminated.
USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS In preparing our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP), we make judgments and estimates about the amounts reflected in our consolidated financial statements. As part of our financial reporting process, our management collaborates to determine the necessary information on which to base our judgments and develop estimates used to prepare the consolidated financial statements. We use historical experience and available information to make these judgments and estimates. However, different amounts could be reported using different assumptions and in light of different facts and circumstances. Therefore, actual amounts could differ from the estimates reflected in our consolidated financial statements.
CASH AND CASH EQUIVALENTS Cash investments having original maturities of three months or less are considered cash equivalents. Cash equivalents principally consist of investments in money market funds and bank deposits at June 30, 2021.
ACCOUNTS RECEIVABLE We market our products to a diverse customer base throughout the world. Trade credit is extended based upon periodically updated evaluations of each customer’s ability to satisfy its obligations. We make judgments as to our ability to collect outstanding receivables and provide allowances for the portion of receivables when collection becomes doubtful. Accounts receivable reserves are determined based upon an aging of accounts and a review of specific accounts.
INVENTORIES We use the last-in, first-out (LIFO) method for determining the cost of a significant portion of our United States (U.S.) inventories, and they are stated at the lower of cost or market. The cost of the remainder of our inventories is measured using approximate costs determined on the first-in, first-out basis or using the average cost method, and are stated at the lower of cost or net realizable value. When market conditions indicate an excess of carrying costs over market value, a lower of cost or net realizable value provision or a lower of cost or market provision, as applicable, is recorded. Once inventory is determined to be excess or obsolete, a new cost basis is established that is not subsequently written back up in future periods.
PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are carried at cost. Major improvements are capitalized, while maintenance and repairs are expensed as incurred. Retirements and disposals are removed from cost and accumulated depreciation accounts, with the gain or loss reflected in operating income. Interest related to the construction of major facilities is capitalized as part of the construction costs and is depreciated over the facilities' estimated useful lives.
Depreciation for financial reporting purposes is computed using the straight-line method over the following estimated useful lives: building and improvements over 15-40 years; machinery and equipment over 4-15 years; furniture and fixtures over 5-10 years and computer hardware and software over 3-5 years.

Table of Contents
LONG-LIVED ASSETS We evaluate the recoverability of property, plant and equipment, operating lease right-of-use (ROU) assets and intangible assets that are amortized, whenever events or changes in circumstances indicate the carrying amount of any such assets may not be fully recoverable. Changes in circumstances include technological advances, changes in our business model, capital structure, economic conditions or operating performance. Our evaluation is performed at the asset group level, based upon, among other things, our assumptions about the estimated future undiscounted cash flows these assets are expected to generate. When the sum of the undiscounted cash flows is less than the carrying value, we will recognize an impairment loss to the extent that carrying value exceeds fair value. We apply our best judgment when performing these evaluations to determine if a triggering event has occurred, the undiscounted cash flows used to assess recoverability and the fair value of the asset group.
GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill represents the excess of cost over the fair value of the net assets of acquired companies. Goodwill and other intangible assets with indefinite lives are tested at least annually for impairment. We perform our annual impairment tests during the June quarter in connection with our annual planning process unless there are impairment indicators based on the results of an ongoing cumulative qualitative assessment that warrant a test prior to that quarter. We evaluate the recoverability of goodwill for each of our reporting units by comparing the fair value of each reporting unit with its carrying value. The fair values of our reporting units are determined using a combination of a discounted cash flow analysis and market multiples based upon historical and projected financial information. We apply our best judgment when assessing the reasonableness of the financial projections used to determine the fair value of each reporting unit. We evaluate the recoverability of indefinite-lived intangible assets using a discounted cash flow analysis based on projected financial information. This evaluation is sensitive to changes in market interest rates and other external factors.
The majority of our intangible assets with definite lives are amortized on a straight-line basis, while certain customer-related intangible assets are amortized on an accelerated method. Identifiable assets with finite lives are reviewed for impairment when events or circumstances indicate that the carrying value may not be recoverable.
PENSION AND OTHER POSTRETIREMENT BENEFITS We sponsor these types of benefit plans for certain employees and retirees. Accounting for the cost of these plans requires the estimation of the cost of the benefits to be provided well into the future and attributing that cost over either the expected work life of employees or over average life of participants participating in these plans, depending on plan status and on participant population. This estimation requires our judgment about the discount rate used to determine these obligations, expected return on plan assets, rate of future compensation increases, rate of future health care costs, withdrawal and mortality rates and participant retirement age. Differences between our estimates and actual results may significantly affect the cost of our obligations under these plans.
In the valuation of our pension and other postretirement benefit liabilities, management utilizes various assumptions. Discount rates are derived by identifying a theoretical settlement portfolio of high quality corporate bonds sufficient to provide for a plan’s projected benefit payments. This rate can fluctuate based on changes in the corporate bond yields.
The long-term rate of return on plan assets is estimated based on an evaluation of historical returns for each asset category held by the plans, coupled with the current and short-term mix of the investment portfolio. The historical returns are adjusted for expected future market and economic changes. This return will fluctuate based on actual market returns and other economic factors.
The rate of future health care costs is based on historical claims and enrollment information projected over the next year and adjusted for administrative charges. This rate is expected to decrease until 2027.
Future compensation rates, withdrawal rates and participant retirement age are determined based on historical information. These assumptions are not expected to significantly change. Mortality rates are determined based on a review of published mortality tables.
EARNINGS PER SHARE Basic earnings per share is computed using the weighted average number of shares outstanding during the period, while diluted earnings per share is calculated to reflect the potential dilution that would occur related to the issuance of capital stock under stock option grants, performance awards and restricted stock units. The difference between basic and diluted earnings per share relates solely to the effect of capital stock options, performance awards and restricted stock units.
The following tables provide the computation of diluted shares outstanding:

(in thousands) |  |  | 2021 |  | 2019
Weighted-average shares outstanding during period |  |  | 83,602 |  |  | 82,379 |
Add: Unexercised stock options and unvested restricted stock units |  |  | 731 |  |  | 912 |
Number of shares on which diluted earnings per share is calculated |  |  | 84,333 |  |  | 83,291 |
Unexercised stock options with an exercise price greater than the average market price and restricted stock units not included in the computation because they were anti-dilutive |  |  | 295 |  |  | 427 |

Table of Contents
In 2020, the effect of unexercised capital stock options, unvested performance awards and unvested restricted stock units was anti-dilutive as a result of a net loss in the period and therefore has been excluded from diluted shares outstanding as well as from the diluted earnings per share calculation.
REVENUE RECOGNITION The Company's contracts with customers are comprised of purchase orders, and for larger customers, may also include long-term agreements. We account for a contract when it has approval and commitment from both parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable. These contracts with customers typically relate to the manufacturing of products, which represent single performance obligations that are satisfied when control of the product passes to the customer. The Company considers the timing of right to payment, transfer of risk and rewards, transfer of title, transfer of physical possession and customer acceptance when determining when control transfers to the customer. As a result, revenue is generally recognized at a point in time - either upon shipment or delivery - based on the specific shipping terms in the contract. The shipping terms vary across all businesses and depend on the product, customary local commercial terms and the type of transportation. Shipping and handling activities are accounted for as activities to fulfill a promise to transfer a product to a customer and as such, costs incurred are recorded when the related revenue is recognized. Payment for products is due within a limited time period after shipment or delivery, typically within 30 to 90 calendar days of the respective invoice dates. The Company does not generally offer extended payment terms.
Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. Amounts billed and due from our customers are classified as accounts receivable, less allowance for doubtful accounts on the consolidated balance sheets. Certain contracts with customers, primarily distributor customers, have an element of variable consideration that is estimated when revenue is recognized under the contract. Variable consideration primarily includes volume incentive rebates, which are based on achieving a certain level of purchases and other performance criteria as established by our distributor programs. These rebates are estimated based on projected sales to the customer and accrued as a reduction of net sales as they are earned. The majority of our products are consumed by our customers or end users in the manufacture of their products. Historically, we have experienced very low levels of returned products and do not consider the effect of returned products to be material. We have recorded an estimated returned goods allowance to provide for any potential returns.
We warrant that products sold are free from defects in material and workmanship under normal use and service when correctly installed, used and maintained. This warranty terminates 30 days after delivery of the product to the customer and does not apply to products that have been subjected to misuse, abuse, neglect or improper storage, handling or maintenance. Products may be returned to Kennametal only after inspection and approval by Kennametal and upon receipt by the customer of shipping instructions from Kennametal. We have included an estimated allowance for warranty returns in our returned goods allowance discussed above.
See "Note 21. Segment Data" for disaggregation of revenue by geography and end market.
The Company records a contract asset when it has a right to payment from a customer that is conditioned on events that have occurred other than the passage of time. The Company also records a contract liability when customers prepay but the Company has not yet satisfied its performance obligation. The Company did not have any material remaining performance obligations, contract assets or liabilities as of June 30, 2021 and 2020.
The Company pays sales commissions related to certain contracts, which qualify as incremental costs of obtaining a contract. However, the Company applies the practical expedient that allows an entity to recognize incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that would have been recognized is one year or less. These costs are recorded within operating expense in our consolidated statements of income.
SHIPPING AND HANDLING FEES AND COSTS All fees billed to customers for shipping and handling are classified as a component of sales. All costs associated with shipping and handling are classified as a component of cost of goods sold.
STOCK-BASED COMPENSATION We recognize stock-based compensation expense for all stock options, restricted stock awards and restricted stock units over the period from the date of grant to the date when the award is no longer contingent on the employee providing additional service (substantive vesting period), net of expected forfeitures. We utilize the Black-Scholes valuation method to establish the fair value of all stock option awards. Time vesting stock units are valued at the market value of the stock on the grant date. Performance vesting stock units with a market condition are valued using a Monte Carlo model.

Capital stock options are granted to eligible employees at fair market value at the date of grant. Capital stock options are exercisable under specified conditions for up to 10 years from the date of grant. The Kennametal Inc. Stock and Incentive Plan of 2010, as Amended and Restated on October 22, 2013, and further amended on January 27, 2015 (A/R 2010 Plan), by the Kennametal Inc. 2016 Stock and Incentive Plan, and on October 27, 2020 by the Kennametal Inc. 2020 Stock and Incentive Plan (2020 Plan) authorize the issuance of up to 9,500,000 shares of the Company’s capital stock plus any shares remaining unissued under the Kennametal Inc. Stock and Incentive Plan of 2002, as amended (2002 Plan). Under the provisions of the A/R 2010 Plan and 2020 Plan participants may deliver stock, owned by the holder for at least six months, in payment of the option price and receive credit for the fair market value of the shares on the date of delivery. The fair market value of shares delivered during 2021, 2020 and 2019 was immaterial. In addition to stock option grants, the A/R 2010 Plan and the 2020 Plan permit the award of stock appreciation rights, performance share awards, performance unit awards, restricted stock awards, restricted unit awards and share awards to directors, officers and key employees.
RESEARCH AND DEVELOPMENT COSTS Research and development costs of $39.5 million, $38.7 million and $39.0 million in 2021, 2020 and 2019, respectively, were expensed as incurred. These costs are included in operating expense in the consolidated statements of income.
INCOME TAXES Deferred income taxes are recognized based on the future income tax effects (using enacted tax laws and rates) of differences in the carrying amounts of assets and liabilities for financial reporting and tax purposes. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not (greater than 50 percent) that a tax benefit will not be realized. In evaluating the need for a valuation allowance, we consider all potential sources of taxable income, including income available in carryback periods, future reversals of taxable temporary differences, projections of taxable income, and income from tax planning strategies, as well as all available positive and negative evidence. Positive evidence includes factors such as a history of profitable operations, and projections of future profitability within the carry forward period, including taxable income from tax planning strategies. Negative evidence includes items such as cumulative losses, projections of future losses, or carryforward periods that are not long enough to allow for the utilization of the deferred tax asset based on existing projections of income. Upon changes in facts and circumstances, we may conclude that deferred tax assets for which no valuation allowance is currently recorded may not be realized, resulting in a charge to establish a valuation allowance. Existing valuation allowances are re-examined under the same standards of positive and negative evidence. If it is determined that it is more likely than not that a deferred tax asset will be realized, the appropriate amount of the valuation allowance, if any, is released.
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES As part of our financial risk management program, we use certain derivative financial instruments. We do not enter into derivative transactions for speculative purposes and, therefore, hold no derivative instruments for trading purposes. We use derivative financial instruments to provide predictability to the effects of changes in foreign exchange rates on our consolidated results. Our objective in managing foreign exchange exposures with derivative instruments is to reduce volatility in cash flow, allowing us to focus more of our attention on business operations. With respect to interest rate management, we use forward-starting interest rate swaps to effectively hedge the variability in future benchmark interest payments attributable to changes in interest rates on forecasted issuances of fixed-rate debt.
We account for derivative instruments as a hedge of the related asset, liability, firm commitment or anticipated transaction, when the derivative is specifically designated as a hedge of such items. We measure hedge effectiveness by assessing the changes in the fair value or expected future cash flows of the hedged item. Certain currency forward contracts hedging significant cross-border intercompany loans are considered other derivatives and, therefore, do not qualify for hedge accounting.
CASH FLOW HEDGES Currency Forward contracts and range forward contracts (a transaction where both a put option is purchased and a call option is sold) are designated as cash flow hedges and hedge anticipated cash flows from cross-border intercompany sales of products and services. Gains and losses realized on these contracts are recorded in accumulated other comprehensive loss, and are recognized as a component of other income, net when the underlying sale of products or services is recognized into earnings.
Interest Rate Forward starting interest rate swap contracts are designated as cash flow hedges and hedge a portion of the interest rate risk related to anticipated issuances of debt. Gains and losses realized on these contracts are recorded in accumulated other comprehensive loss, and are recognized as a component of interest expense when the interest payments on the future debt interest are recognized into earnings.
NET INVESTMENT HEDGES We designate financial instruments as net investment hedges from time to time to hedge the foreign exchange exposure of our net investment in foreign currency-based subsidiaries. The remeasurements of these non-derivatives designated as net investment hedges are calculated each period with changes reported in foreign currency translation adjustment within accumulated other comprehensive loss. Such amounts will remain in accumulated other comprehensive loss unless we complete or substantially complete liquidation or disposal of our investment in the underlying foreign operations.
42

Table of Contents
CURRENCY TRANSLATION Assets and liabilities of international operations are translated into U.S. dollars using year-end exchange rates, while revenues and expenses are translated at average exchange rates throughout the year. The resulting net translation adjustments are recorded as a component of accumulated other comprehensive loss. The local currency is the functional currency of most of our locations.
Losses of $3.3 million, $3.4 million and $2.7 million from currency transactions were included in other income, net in 2021, 2020 and 2019, respectively.
NEW ACCOUNTING STANDARDS Effective July 1, 2020, the Company adopted Accounting Standards Update (ASU) No. 2016-13, Financial Instruments – Credit Losses. This ASU added a new impairment model (known as the current expected credit loss (CECL) model) that is based on expected losses rather than incurred losses. The new guidance applies to all financial assets, including trade receivables. The Company adopted the ASU on a modified retrospective approach. Under this method of adoption, there was no cumulative-effect adjustment to beginning retained earnings on the consolidated balance sheets. Adoption of this standard did not have a material effect on the Company's consolidated financial statements.

NOTE 4 — DIVESTITURE
During the year ended June 30, 2020, we completed the sale of certain assets of the non-core specialty alloys and metals business within the Infrastructure segment located in New Castle, Pennsylvania to Advanced Metallurgical Group N.V. for an aggregate price of $24.0 million.
The net book value of these assets at closing was $29.5 million, and the pre-tax loss on divestiture recognized during the year ended June 30, 2020 was $6.5 million. Transaction proceeds were primarily used for capital expenditures related to our simplification/modernization efforts.
NOTE 5 — FAIR VALUE MEASUREMENTS
Fair value is defined as 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. The fair value hierarchy consists of three levels to prioritize the inputs used in valuations, as defined below:
Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3: Inputs that are unobservable.

Table of Contents
Certain currency forward contracts that hedge significant cross-border intercompany loans are considered as other derivatives and therefore do not qualify for hedge accounting. These contracts are recorded at fair value in the consolidated balance sheets, with the offset to other income, net. Losses related to derivatives not designated as hedging instruments have been recognized as follows:

(in thousands) | 2021 |  | 2020 |  | 2019
Other income, net - currency forward contracts | $ | 2 |  |  | $ | 210 |  |  | $ | 108 |

CASH FLOW HEDGES
Range forward contracts (a transaction where both a put option is purchased and a call option is sold) are designated as cash flow hedges and hedge anticipated cash flows from cross-border intercompany sales of products and services. Gains and losses related to these contracts are recorded in accumulated other comprehensive loss and are recognized as a component of cost of goods sold and other income, net when the underlying sale of products or services is recognized into earnings. All outstanding range forward contracts expired as of June 30, 2021. The notional amount of the contracts translated into U.S. dollars at June 30, 2020 was $2.2 million. The time value component of the fair value of range forward contracts is excluded from the assessment of hedge effectiveness.
During fiscal 2020 we entered into seven forward-starting interest rate swap contracts with an aggregate notional amount totaling $200.0 million. A forward-starting interest rate swap is an agreement that effectively hedges the variability in future benchmark interest payments attributable to changes in interest rates on the forecasted issuance of fixed-rate debt. During fiscal 2021, upon issuance of the Senior Unsecured Notes due 2031 (see Note 11 for more information) we settled the forward starting interest rate swap contracts for a gain of $10.2 million in other comprehensive income (loss). The gain will be amortized out of accumulated other comprehensive income (loss) and into interest expense (as a benefit) over the life of the Senior Unsecured Notes due 2031. The notional amount of the forward starting interest rate swap contracts at June 30, 2020 was $200.0 million. We recorded $2.1 million of liabilities as of June 30, 2020 related to these contracts. No portion of the gains or losses recognized in earnings was due to ineffectiveness and no amounts were excluded from our effectiveness testing for the years ended June 30, 2021 and 2020. There were no interest rate swap contracts outstanding at June 30, 2021.
NET INVESTMENT HEDGES
As of June 30, 2021 and 2020, we had foreign currency-denominated intercompany loans payable with total aggregate principal amounts of €5.2 million and €15.9 million, respectively, designated as net investment hedges to hedge the foreign exchange exposure of our net investment in Euro-based subsidiaries. The notional value of the contract, which has a maturity of June 26, 2022, was €5.2 million, or $6.1 million, as of June 30, 2021. A loss of $1.9 million and gains of $0.6 million and $2.4 million were recorded as a component of foreign currency translation adjustments in other comprehensive income (loss) during 2021, 2020 and 2019, respectively.
As of June 30, 2021 and 2020, the foreign currency-denominated intercompany loans payable designated as net investment hedges consisted of:

(in thousands) | 2021 | 2020 |
Instrument | Notional (EUR)(2) | Notional (USD)(2) | Notional (EUR)(2) | Notional (USD)(2) | Maturity
Foreign currency-denominated intercompany loan payable | €5,173 | $6,146 | €15,907 | $17,833 | June 26, 2022

NOTE 8 — GOODWILL AND OTHER INTANGIBLE ASSETS
As of June 30, 2021, $277.6 million of goodwill was allocated to the Metal Cutting reporting unit. We completed an annual quantitative test of goodwill impairment and determined that the fair value of the reporting unit substantially exceeded the carrying value and, therefore, no impairment was recorded during fiscal 2021. Further, an indefinite-lived trademark intangible asset of $11.8 million in the Metal Cutting reporting unit had a fair value that approximated its carrying value as of the date of the annual impairment test and, therefore, no impairment was recorded during fiscal 2021.
December Quarter of Fiscal 2020 Impairment Charge
In the December quarter of fiscal 2020, the Company experienced deteriorating market conditions, primarily in general engineering and transportation applications in India and China, in addition to overall global weakness in the manufacturing sector. In view of these declining conditions and the significant detrimental effect on cash flows and actual and projected revenue and earnings compared with the fiscal 2019 annual impairment test, we determined that an impairment triggering event had occurred and performed an interim quantitative impairment test of our goodwill, indefinite-lived trademark intangible asset and other long-lived assets of our former Widia reporting unit. We evaluated the recoverability of goodwill for the reporting unit by comparing the fair value with its carrying value, with the fair values determined using a combination of a discounted cash flow analysis and market multiples based upon historical and projected financial information. As a result of this interim test, we recorded a non-cash pre-tax impairment charge during the three months ended December 31, 2019 of $14.6 million in the former Widia segment, which is now part of the Metal Cutting segment as of July 1, 2020, of which $13.1 million was for goodwill and $1.5 million was for an indefinite-lived trademark intangible asset. These impairment charges were recorded in goodwill and other intangible assets impairments in our consolidated statements of income. No impairment was recorded for the other long-lived assets.
March Quarter of Fiscal 2020 Impairment Charge
In the March quarter of fiscal 2020, the decline in actual and projected financial results for the former Widia reporting unit, primarily as a result of the COVID-19 pandemic, represented an interim impairment triggering event because there was essentially zero cushion between the reporting unit's carrying value and fair value as of March 31 2020. This is because the former Widia reporting unit was recorded at fair value as of the December 31, 2019 interim impairment testing date. We evaluated the recoverability of goodwill for the reporting unit by comparing the fair value with its carrying value, with the fair values determined using a combination of a discounted cash flow analysis and market multiples based upon historical and projected financial information. As a result of this interim test, we recorded a non-cash pre-tax impairment charge during the three months ended March 31, 2020 of $15.6 million in the former Widia segment, of which $13.7 million was for goodwill and $1.9 million was for an indefinite-lived trademark intangible asset. These impairment charges were recorded in goodwill and other intangible assets impairments in our consolidated statements of income. No impairment was recorded for the other long-lived assets.

Amortization expense for intangible assets was $14.0 million, $13.8 million and $14.4 million for 2021, 2020 and 2019, respectively. Estimated amortization expense for 2022 through 2026 is $12.5 million, $12.3 million, $11.1 million, $9.9 million, and $9.5 million, respectively.
NOTE 9 — LEASES
At the inception of our contracts we determine if the contract is or contains a lease. A contract is or contains a lease if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration. ROU assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term at commencement. For leases that do not have a readily determinable implicit rate, we use a discount rate based on our incremental borrowing rate, which is determined considering factors such as the lease term, our credit rating and the economic environment of the location of the lease as of the commencement date.
We account for non-lease components separately from lease components. These costs often relate to the payments for a proportionate share of real estate taxes, insurance, common area maintenance and other operating costs in addition to base rent. We also do not recognize ROU assets and liabilities for leases with an initial term of 12 months or less. Lease costs associated with leases of less than 12 months were $2.4 million and $6.4 million for the years ended June 30, 2021 and 2020, respectively.

Table of Contents
As a lessee, we have various operating lease agreements primarily related to real estate, vehicles and office and plant equipment. Our real estate leases, which are comprised primarily of manufacturing, warehousing, office and administration facilities, represent a majority of our lease liability. Our lease payments are largely fixed. Any variable lease payments, including utilities, common area maintenance and repairs and maintenance, are expensed during the period incurred. Variable lease costs were immaterial for the year ended June 30, 2021 and 2020. A majority of our real estate leases include options to extend the lease and options to early terminate the lease. Leases with an early termination option generally involve a termination payment. We review all options to extend, terminate, or purchase the ROU assets at the inception of the lease and account for these options when they are reasonably certain of being exercised. Our lease agreements generally do not contain any material residual value guarantees or materially restrictive covenants. We do not have any material leases that have been signed but not commenced, and we did not have any lease transactions with related parties.
Operating lease expense is recognized on a straight-line basis over the lease term and is included in operating expense on our consolidated statements of income. Operating lease cost was $20.2 million, $22.6 million and $26.6 million in 2021, 2020 and 2019, respectively.

Total long-term debt | $ | 592,108 |  |  | $ | 594,083 |

Senior Unsecured Notes In February 2021, we issued $300.0 million of 2.800 percent Senior Unsecured Notes with a maturity date of March 1, 2031. Interest will be paid semi-annually on March 1 and September 1 of each year. We settled forward starting interest rate swap contracts for a gain of $10.2 million related to the bond issuance as discussed in Note 6. In March 2021, we used the net proceeds from the bond issuance, plus cash on hand, for the early extinguishment of our $300.0 million of 3.875 percent Senior Unsecured Notes due 2022 (the 2022 Senior Notes). Due to the early extinguishment, interest expense during fiscal 2021 includes a make-whole premium of $9.6 million and the acceleration of a loss in the amount of $2.6 million from other comprehensive loss related to forward starting interest rate contracts that were used to hedge the interest payments of the 2022 Senior Notes. A stranded tax benefit associated with the termination of this hedge was also recognized during fiscal 2021. Refer to Note 13 for more information related to the stranded tax benefit. On June 7, 2018, we issued $300.0 million of 4.625 percent Senior Unsecured Notes with a maturity date of June 15, 2028. Interest on these notes is paid semi-annually on June 15 and December 15 of each year.
Future principal maturities of long-term debt are $300.0 million in 2028 and $300.0 million in 2031.
Fixed rate debt had a fair market value of $644.2 million and $630.2 million at June 30, 2021 and 2020, respectively. The Level 2 fair value is determined based on the quoted market prices for similar debt instruments as of June 30, 2021 and 2020, respectively.
NOTE 12 — REVOLVING AND OTHER LINES OF CREDIT AND NOTES PAYABLE
Credit Agreement During the three months ended September 30, 2020, we entered into the First Amendment (the Amendment) to the Fifth Amended and Restated Credit Agreement dated as of June 21, 2018, (as amended by the Amendment, the Credit Agreement). The Credit Agreement is a five-year, multi-currency, revolving credit facility, which we use to augment cash from operations and as an additional source of funds. The Credit Agreement provides for revolving credit loans of up to $700.0 million for working capital, capital expenditures and general corporate purposes. The Credit Agreement allows for borrowings in U.S. dollars, euros, Canadian dollars, pounds sterling and Japanese yen. Interest payable under the Credit Agreement is based upon the type of borrowing under the facility and may be (1) LIBOR plus an applicable margin, (2) the greater of the prime rate or the Federal Funds effective rate plus an applicable margin, or (3) fixed as negotiated by us. The Credit Agreement matures in June 2023.
The Credit Agreement requires us to comply with various restrictive and affirmative covenants, including two financial covenants: (1) a maximum leverage ratio where debt, net of domestic cash in excess of $25 million and sixty percent of the unrestricted cash held outside of the United States, must be less than or equal to 3.5 times trailing twelve months EBITDA (temporarily increased by the Amendment to 4.25 times trailing twelve months EBITDA during the period from September 30, 2020 through and including December 31, 2021), adjusted for certain non-cash expenses and which may be further adjusted, at our discretion, to include up to $120 million of cash restructuring charges through December 31, 2021; and (2) a minimum consolidated interest coverage ratio of EBITDA to interest of 3.5 times (as such terms are defined in the Credit Agreement). Borrowings under the Credit Agreement are guaranteed by our significant domestic subsidiaries.
As of June 30, 2021, we were in compliance with all covenants of the Credit Agreement and we had no borrowings outstanding and $700.0 million of availability. There were $500.0 million borrowings outstanding as of June 30, 2020. The weighted average interest rate on borrowings under the Credit Agreement was 3.1 percent for the year ended June 30, 2021.
Other lines of credit and notes payable were $8.4 million and $0.4 million at June 30, 2021 and 2020, respectively. The lines of credit represented short-term borrowings under credit lines with commercial banks in the various countries in which we operate. These credit lines, translated into U.S. dollars at June 30, 2021 exchange rates, totaled $65.0 million.

Coronavirus Aid, Relief, and Economic Security Act (CARES Act)
On March 27, 2020, the CARES Act was enacted in response to the COVID-19 pandemic. The CARES Act, among other things, allows net operating losses arising in taxable years beginning after December 31, 2017 and before January 1, 2021 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes; permits net operating loss carryovers and carrybacks to offset 100 percent of taxable income for taxable years beginning before January 1, 2021; and modifies the limitation on business interest by increasing the allowable business interest deduction from 30 percent of adjusted taxable income to 50 percent of adjusted taxable income for taxable years beginning in 2019 or 2020. We carried back our taxable loss in the U.S. for fiscal 2020 under the provisions of the CARES Act and recorded a benefit in our tax provision during fiscal 2020.
Swiss tax reform
Legislation was effectively enacted during the December quarter of fiscal 2020 when the Canton of Schaffhausen approved the Federal Act on Tax Reform and AHV Financing on October 8, 2019 (Swiss tax reform). Significant changes from Swiss tax reform include the abolishment of certain favorable tax regimes and the creation of a multi-year transitional period at both the federal and cantonal levels.
The transitional provisions of Swiss tax reform allow companies to utilize a combination of lower tax rates and tax basis adjustments to fair value, which are used for tax depreciation and amortization purposes resulting in deductions over the transitional period. To reflect the federal and cantonal transitional provisions, as they apply to us, we recorded a deferred tax asset of $14.5 million during the December quarter of fiscal 2020. We consider the deferred tax asset from Swiss tax reform to be an estimate based on our current interpretation of the legislation, which is subject to change based on further legislative guidance, review with the Swiss federal and cantonal authorities, and modifications to the underlying valuation. We anticipate finalization of the deferred tax asset within the next twelve months.

During 2021, we recorded a tax benefit of $3.5 million for the recognition of a stranded deferred tax balance in accumulated other comprehensive loss associated with the forward starting interest rate swap contracts that were terminated when the 2022 Senior Notes were extinguished. The impact of this item is included in the tax reconciliation table under the caption “Recognition of stranded deferred tax balance” and in the consolidated statements of cash flows as a non-cash item within the caption "Debt refinancing charge."
During 2021, we recorded a net tax benefit of $9.3 million related to a tax election made in our fiscal 2020 U.S. income tax return pursuant to global intangible low-taxed income (GILTI) regulations which were issued during the current fiscal year. The impact of this item is included in the tax reconciliation table under the caption “U.S. income taxes provided on international income.”
During 2019, we recorded a net tax benefit of $9.3 million associated with the finalization of our toll tax charge which included a benefit of $14.5 million for the toll tax charge and a $5.3 million charge for an unrecognized tax benefit. The effect of these items is included in the tax reconciliation table under the caption “Combined effects of U.S. tax reform.”
During 2019, we released a $1.1 million valuation allowance that was previously recorded against the net deferred tax assets of our Australian subsidiary. The effect of this item is included in the tax reconciliation table under the caption “Change in valuation allowance and other uncertain tax positions.”

As of June 30, 2021, we have $26.3 million of U.S. net deferred tax assets. Within this amount is $57.0 million related to net operating loss, tax credit, and other carryforwards that can be used to offset future U.S. taxable income. Certain of these carryforwards will expire if they are not used within a specified timeframe. At this time, we consider it more likely than not that we will have sufficient U.S. taxable income in the future that will allow us to realize these net deferred tax assets. However, it is possible that some or all of these tax attributes could ultimately expire unused, especially if our end markets do not continue to recover from the COVID-19 global pandemic. Therefore, if we are unable to generate sufficient U.S. taxable income from our operations, a valuation allowance to reduce the U.S. net deferred tax assets may be required, which would materially increase income tax expense in the period in which the valuation allowance is recorded.
Included in deferred tax assets at June 30, 2021 is $32.5 million associated with tax credits and other carryforward items in the U.S. Of that amount, $0.7 million expires through 2031, $4.6 million expires through 2036, $18.3 million expires through 2041, $2.6 million does not expire, and $6.3 million is amortizable over eight years.
Included in deferred tax assets at June 30, 2021 is $44.3 million associated with NOL carryforwards in U.S. federal, state and foreign jurisdictions. Of that amount, $8.1 million expires through 2026, $2.2 million expires through 2031, $2.7 million expires through 2036, $3.8 million expires through 2041, and the remaining $27.5 million does not expire. The realization of these tax benefits is primarily dependent on future taxable income in these jurisdictions.
A valuation allowance of $21.3 million has been placed against deferred tax assets primarily in U.S. state, Brazil and Bolivia jurisdictions, all of which would be allocated to income tax expense upon realization of the deferred tax assets. As the respective operations generate sufficient income, the valuation allowances will be partially or fully reversed at such time we believe it will be more likely than not that the deferred tax assets will be realized. In 2021, the valuation allowance related to these deferred tax assets increased by $4.6 million.
We consider the majority of the $1.5 billion unremitted earnings of our non-U.S. subsidiaries to be permanently reinvested. With regard to these unremitted earnings, we have not, nor do we anticipate the need to, repatriate funds to the U.S. to satisfy domestic liquidity needs arising in the ordinary course of business, including liquidity needs associated with our domestic debt service requirements. Determination of the amount of unrecognized deferred tax liability related to indefinitely reinvested earnings is not practicable due to our legal entity structure and the complexity of U.S. and local tax laws. With regard to the small portion of unremitted earnings that are not indefinitely reinvested, we maintain a deferred tax liability for foreign withholding and U.S. state income taxes. The deferred tax liability associated with unremitted earnings of our non-U.S. subsidiaries not permanently reinvested is $6.4 million as of June 30, 2021.

A reconciliation of the beginning and ending amount of unrecognized tax benefits (excluding interest and penalty) is as follows as of June 30:

(in thousands) |  | 2021 |  | 2020 |  | 2019
Balance at beginning of year |  | $ | 8,680 |  |  | $ | 8,952 |  |  | $ | 5,775 |
Increases for tax positions of prior years |  | — |  |  | — |  |  | 7,384 |

Balance at end of year |  | $ | 8,656 |  |  | $ | 8,680 |  |  | $ | 8,952 |

The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate in 2021, 2020 and 2019 is $8.7 million, $8.7 million and $9.0 million, respectively. We believe that it is reasonably possible that the amount of unrecognized tax benefits will decrease by approximately $5.3 million within the next twelve months.
Our policy is to recognize interest and penalties related to income taxes as a component of the provision for income taxes in the consolidated statements of income. We recognized a decrease of $0.2 million and $0.4 million in 2021 and 2019, respectively, and an increase of $1.0 million in 2020. As of June 30, 2021 and 2020, the amount of interest accrued was $1.4 million and $1.2 million, respectively. As of June 30, 2021 there was no penalty accrued and at June 30, 2020, the amount of penalty accrued was $0.5 million.
With few exceptions, we are no longer subject to income tax examinations by tax authorities for years prior to 2015. The Internal Revenue Service has audited or the statute of limitations has expired for all U.S. tax years prior to 2018. Various state and foreign jurisdiction tax authorities are in the process of examining our income tax returns for various tax years ranging from 2015 to 2018. We continuously review our uncertain tax positions and evaluate any potential issues that may lead to an increase or decrease in the total amount of unrecognized tax benefits recorded.
NOTE 14 — PENSION AND OTHER POSTRETIREMENT BENEFITS
Defined Benefit Pension Plans
We have defined benefit pension plans that cover certain employees in the U.S., Germany, the UK, Switzerland, Canada and Israel. Pension benefits under defined benefit pension plans are based on years of service and, for certain plans, on average compensation for specified years preceding retirement. We fund pension costs in accordance with the funding requirements of the Employee Retirement Income Security Act of 1974 (ERISA), as amended, for U.S. plans and in accordance with local regulations or customs for non-U.S. plans. The accrued benefit for all participants in the Kennametal Inc. Retirement Income Plan was frozen as of December 31, 2016. The majority of our defined benefit pension plans are closed to future participation.
We have an Executive Retirement Plan for certain executives and a Supplemental Executive Retirement Plan both of which have been closed to future participation on June 15, 2017 and July 26, 2006, respectively.
We presently provide varying levels of postretirement health care and life insurance benefits to certain employees and retirees. By fiscal 2019, participants over the age of 65 were transitioned to a private exchange and some received a fixed Health Retirement Account (HRA) contribution to offset the cost of their coverage. Postretirement health and life benefits are closed to future participants as of December 31, 2016.
We use a June 30 measurement date for all of our plans. During fiscal 2021, as part of the plan to wind-up the fully frozen, overfunded Canadian defined benefit pension plans, the Company purchased an upfront annuity for retirees resulting in a non-cash settlement charge of $2.8 million. The Company expects to complete the wind-up of the Canadian plans by fiscal 2023.

Total | $ | 281,906 |  |  | $ | 308,261 |

To the best of our knowledge and belief, the asset portfolios of our defined benefit pension plans do not contain our capital stock. Apart from the partial annuitization of the Canadian plans as previously mentioned, we do not issue insurance contracts to cover future annual benefits of defined benefit pension plan participants. Transactions between us and our defined benefit pension plans include the reimbursement of plan expenditures incurred by us on behalf of the plans. To the best of our knowledge and belief, the reimbursement of cost is permissible under current ERISA rules or local government law. The accumulated benefit obligation for all defined benefit pension plans was $967.5 million and $1,001.8 million as of June 30, 2021 and 2020, respectively.

Assumptions
The significant actuarial assumptions used to determine the present value of net benefit obligations for our defined benefit pension plans and other postretirement benefit plans were as follows:

| 2021 |  | 2020 |  | 2019
Discount Rate: |  |  |  |  |
U.S. plans | 1.2-3.0% |  | 1.6-2.9% |  | 2.7-3.6%
International plans | 0.3-3.2% |  | 0.2-2.4% |  | 0.4-2.9%
Rates of future salary increases: |  |  |  |  |
U.S. plans (Executive Retirement Plan only) | 4.0 | % |  | 4.0 | % |  | 4.0 | %
International plans | 1.5 | % |  | 1.5 | % |  | 1.8-3.0%

The significant assumptions used to determine the net periodic income for our pension and other postretirement benefit plans were as follows:

| 2021 |  | 2020 |  | 2019
Discount Rate: |  |  |  |  |
U.S. plans | 1.2-3.0% |  | 2.7-3.6% |  | 4.0-4.3%
International plans | 0.3-3.2% |  | 0.4-2.9% |  | 1.8-3.3%
Rates of future salary increases: |  |  |  |  |
U.S. plans (Executive Retirement Plan only) | 4.0 | % |  | 4.0 | % |  | 4.0 | %
International plans | 1.5 | % |  | 1.8-3.0% |  | 2.5-3.0%
Rate of return on plans assets: |  |  |  |  |
U.S. plans | 6.8 | % |  | 7.0 | % |  | 7.0 | %
International plans | 0.2-5.3% |  | 0.4-5.3% |  | 5.0-5.3%

56

Table of Contents
The rates of return on plan assets are based on historical performance, as well as future expected returns by asset class considering macroeconomic conditions, current portfolio mix, long-term investment strategy and other available relevant information.
The annual assumed rate of increase in the per capita cost of covered benefits (the health care cost trend rate) for our postretirement benefit plans was as follows:

| 2021 |  | 2020 |  | 2019
Health care costs trend rate assumed for next year | 6.5 | % |  | 6.8 | % |  | 7.0 | %
Rate to which the cost trend rate gradually declines | 5.0 | % |  | 5.0 | % |  | 5.0 | %
Year that the rate reaches the rate at which it is assumed to remain | 2027 |  | 2027 |  | 2027

A change of one percentage point in the assumed health care cost trend rates would have an immaterial effect on both the total service and interest cost components of our other postretirement cost and other postretirement benefit obligation at June 30, 2021.
Plan Assets
The primary objective of certain of our pension plans' investment policies is to ensure that sufficient assets are available to provide the benefit obligations at the time the obligations come due. The overall investment strategy for the defined benefit pension plans' assets combine considerations of preservation of principal and moderate risk-taking. The assumption of an acceptable level of risk is warranted in order to achieve satisfactory results consistent with the long-term objectives of the portfolio. Fixed income securities comprise a significant portion of the portfolio due to their plan-liability-matching characteristics and to address the plans' cash flow requirements. Additionally, diversification of investments within each asset class is utilized to further reduce the effect of losses in single investments.
Investment management practices for U.S. defined benefit pension plans must comply with ERISA and all applicable regulations and rulings thereof. The use of derivative instruments is permitted where appropriate and necessary for achieving overall investment policy objectives. Currently, the use of derivative instruments is not significant when compared to the overall investment portfolio.
The Company utilizes a liability driven investment strategy (LDI) for the assets of its U.S. defined benefit pension plans in order to reduce the volatility of the funded status of these plans and to meet the obligations at an acceptable cost over the long term. This LDI strategy entails modifying the asset allocation and duration of the assets of the plans to more closely match the liability profile of these plans. The asset reallocation involves increasing the fixed income allocation, reducing the equity component and adding alternative investments. Longer duration interest rate swaps have been utilized periodically in order to increase the overall duration of the asset portfolio to more closely match the liabilities.
Our defined benefit pension plans’ asset allocations as of June 30, 2021 and 2020 and target allocations for 2022, by asset class, were as follows:

| 2021 |  | 2020 |  | Target %
Equity | 20 | % |  | 22 | % |  | 20 | %
Fixed Income | 76 | % |  | 75 | % |  | 80 | %
Other | 4 | % |  | 3 | % |  | — | %

The following sections describe the valuation methodologies used by the trustee to measure the fair value of the defined benefit pension plan assets, including an indication of the level in the fair value hierarchy in which each type of asset is generally classified (see Note 5 for the definition of fair value and a description of the fair value hierarchy).
Corporate fixed income securities Investments in corporate fixed income securities consist of corporate debt and asset backed securities. These investments are classified as level two and are valued using independent observable market inputs such as the treasury curve, swap curve and yield curve.
Common stock Common stocks are classified as level one and are valued at their quoted market price.
Government securities Investments in government securities consist of fixed income securities such as U.S. government and agency obligations and foreign government bonds and asset and mortgage backed securities such as obligations issued by government sponsored organizations. These investments are classified as level two and are valued using independent observable market inputs such as the treasury curve, credit spreads and interest rates.
Other fixed income securities Investments in other fixed income securities are classified as level two and valued based on observable market data.
57

Table of Contents
Other Other investments consist primarily of state and local obligations and short term investments including cash, corporate notes, and various short term debt instruments which can be redeemed within a nominal redemption notice period. These investments are primarily classified as level two and are valued using independent observable market inputs.
The fair value methods described may not be reflective of future fair values. Additionally, while the Company believes the valuation methods used by the plans’ trustee are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in different fair value measurement at the reporting date.

(3) Investments in common / collective trusts invest primarily in publicly traded securities and are valued using net asset value (NAV) of units of a bank collective trust. Therefore, these amounts have not been classified in the fair value hierarchy and are presented in the tables to reconcile the fair value hierarchy to the total fair value of plan assets.
Defined Contribution Plans
We sponsor several defined contribution retirement plans. Costs for defined contribution plans were $13.3 million, $14.7 million and $16.3 million in 2021, 2020 and 2019, respectively.
Certain U.S. employees are eligible to participate in the Kennametal Thrift Plus Plan (Thrift), which is a qualified defined contribution plan under section 401(k) of the Internal Revenue Code. Under the Thrift, eligible employees receive a full match of their contributions up to 6 percent of eligible compensation.
All contributions, including the company match and discretionary, are made in cash and invested in accordance with participants’ investment elections. There are no minimum amounts that must be invested in company stock, and there are no restrictions on transferring amounts out of company stock to another investment choice, other than excessive trading rules applicable to such investments. Employee contributions and our matching and discretionary contributions vest immediately as of the participants' employment dates.

NOTE 16 — RESTRUCTURING AND RELATED CHARGES
FY20 Restructuring Actions
In the June quarter of fiscal 2019, we implemented, and in fiscal 2020 substantially completed, the FY20 Restructuring Actions associated with our simplification/modernization initiative to reduce structural costs, improve operational efficiency and position us for long-term profitable growth. Total restructuring and related charges since inception of $54.8 million were recorded for this program through June 30, 2021, consisting of: $46.6 million in Metal Cutting and $8.3 million in Infrastructure.
FY21 Restructuring Actions
In the September quarter of fiscal 2020, we announced the initiation of restructuring actions in Germany associated with our simplification/modernization initiative to reduce structural costs. Subsequently, we also announced the acceleration of our other structural cost reduction plans including the closing of the Johnson City, Tennessee facility. Expected pre-tax charges for the FY21 Restructuring Actions are approximately $90 million. Total restructuring and related charges since inception of $82.2 million were recorded for this program through June 30, 2021, consisting of: $74.5 million in Metal Cutting and $7.7 million in Infrastructure. The majority of the remaining charges related to the FY21 Restructuring Actions are expected to be in the Metal Cutting segment.

NOTE 17 — FINANCIAL INSTRUMENTS
The methods used to estimate the fair value of our financial instruments are as follows:
Cash and Equivalents, Revolving and Other Lines of Credit and Notes Payable The carrying amounts approximate their fair value because of the short maturity of the instruments.
Long-Term Debt, Including Current Maturities Fixed rate debt had a fair market value of $644.2 million and $630.2 million at June 30, 2021 and 2020, respectively. The Level 2 fair value is determined based on the quoted market prices for similar debt instruments as of June 30, 2021 and 2020, respectively.
Foreign Exchange Contracts All outstanding range forward contracts expired as of June 30, 2021. The notional amount of the contracts translated into U.S. dollars at June 30, 2020 was $2.2 million. We would have received an immaterial amount at June 30, 2020 to settle these contracts representing the fair value of these agreements. The carrying value equaled the fair value for these contracts at June 30, 2020. Fair value was estimated based on quoted market prices of comparable instruments.
Interest Rate Swap Contracts During fiscal 2021, upon issuance of the Senior Unsecured Notes due 2031 (see Note 11 for more information) we settled the forward starting interest rate swap contracts used to hedge a portion of the interest rate risk related to the refinancing. The notional amount of the forward starting interest rate swap contracts at June 30, 2020 was $200.0 million. We recorded $2.1 million of liabilities as of June 30, 2020 related to these contracts. There were no interest rate swap contracts outstanding at June 30, 2021.

Table of Contents
Concentrations of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of temporary cash investments and trade receivables. By policy, we make temporary cash investments with high credit quality financial institutions and limit the amount of exposure to any one financial institution. With respect to trade receivables, concentrations of credit risk are significantly reduced because we serve numerous customers in many industries and geographic areas.
We are exposed to counterparty credit risk for nonperformance of derivatives and, in the unlikely event of nonperformance, to market risk for changes in interest and currency exchange rates, as well as settlement risk. We manage exposure to counterparty credit risk through credit standards, diversification of counterparties and procedures to monitor concentrations of credit risk. We do not anticipate nonperformance by any of the counterparties. As of June 30, 2021 and 2020, we had no significant concentrations of credit risk.
NOTE 18 — STOCK-BASED COMPENSATION
Stock Options
Changes in our stock options for 2021 were as follows:

Tax benefits relating to excess stock-based compensation deductions are presented in the consolidated statements of cash flows as operating cash inflows. Tax benefits resulting from stock-based compensation deductions were greater than the amounts reported for financial reporting purposes by $0.7 million in 2021, and less than amounts reported for financial reporting purposes by an immaterial amount in 2020 and by $1.3 million in 2019.
The amount of cash received from the exercise of capital stock options during 2021, 2020 and 2019 was $6.6 million, $0.9 million and $4.8 million, respectively. The related tax benefit was $0.6 million in 2021, was immaterial in 2020, and was $0.5 million 2019. The total intrinsic value of options exercised in 2021, 2020 and 2019 was $2.4 million, $0.3 million and $2.4 million, respectively.
Restricted Stock Units – Time Vesting and Performance Vesting
Performance vesting restricted stock units are earned pro rata each year if certain performance goals are met over a three-year period, and are also subject to a service condition that requires the individual to be employed by the Company at the payment date after the three-year performance period, with the exception of retirement eligible grantees, who upon retirement are entitled to receive payment for any units that have been earned, including a prorated portion in the partially completed fiscal year in which the retirement occurs. Time vesting stock units are valued at the market value of the stock on the grant date. Performance vesting stock units with a market condition are valued using a Monte Carlo model.

During 2021, 2020 and 2019, compensation expense related to time vesting and performance vesting restricted stock units was $23.9 million, $15.3 million and $21.9 million, respectively. Certain performance metrics related to fiscal 2020 were not met, resulting in an adjustment of 100,000 performance vesting stock units during 2021. As of June 30, 2021, the total unrecognized compensation cost related to unvested time vesting and performance vesting restricted stock units was $22.7 million and is expected to be recognized over a weighted average period of 1.8 years.
NOTE 19— ENVIRONMENTAL MATTERS
The operation of our business has exposed us to certain liabilities and compliance costs related to environmental matters. We are involved in various environmental cleanup and remediation activities at certain sites associated with our current or former operations.
We establish and maintain accruals for certain potential environmental obligations. At June 30, 2021 and 2020, the balances of these liabilities were $14.7 million, of which $2.6 million was current, and $15.6 million, of which $6.1 million was current, respectively. These accruals represent anticipated costs associated with the remediation of these issues and are generally not discounted.
The accruals we have established for environmental liabilities represent our best current estimate of the probable and reasonably estimable costs of addressing identified environmental situations, based on our review of currently available evidence, and taking into consideration our prior experience in remediation and that of other companies, as well as public information released by the United States Environmental Protection Agency (USEPA), other governmental agencies and by the Potentially Responsible Party (PRP) groups in which we are participating. Although the accruals currently appear to be sufficient to cover these environmental obligations, there are uncertainties associated with environmental liabilities, and we can give no assurance that our estimate of any environmental liability will not increase or decrease in the future. The recorded and unrecorded liabilities for all environmental concerns could change substantially due to factors such as the nature and extent of contamination, changes in remedial requirements, technological changes, discovery of new information, the financial strength of other PRPs, the identification of new PRPs and the involvement of and direction taken by the government on these matters.
Among other environmental laws, we are subject to the Comprehensive Environmental Response Compensation and Liability Act of 1980, under which we have been identified by the USEPA or other third party as a PRP with respect to environmental remedial costs at certain sites. We have evaluated our claims and potential liability associated with these sites based upon the best information currently available to us. We believe our environmental accruals will be adequate to cover our portion of the environmental remedial costs at those sites where we have been designated a PRP, to the extent these expenses are probable and reasonably estimable.
NOTE 20 — COMMITMENTS AND CONTINGENCIES
Legal Matters Various lawsuits arising during the normal course of business are pending against us. In our opinion, the ultimate liability, if any, resulting from these matters will have no significant effect on our consolidated financial position or results of operations.
Lease Commitments We lease a wide variety of facilities and equipment under operating leases, primarily for warehouses, production and office facilities and equipment. Refer to Note 9 for more information.
Purchase Commitments We have purchase commitments for materials, supplies and machinery and equipment as part of the ordinary conduct of business. Some of these commitments extend beyond one year and are based on minimum purchase requirements. We believe these commitments are not at prices in excess of current market.
64

Other Contractual Obligations We do not have material financial guarantees or other contractual commitments that are reasonably likely to adversely affect our liquidity.
Related Party Transactions Sales to affiliated companies were immaterial in 2021, 2020 and 2019. We do not have any other related party transactions that affect our operations, results of operations, cash flow or financial condition.
NOTE 21 — SEGMENT DATA
The Company manages and reports its business in the following two segments: Metal Cutting and Infrastructure. The Company's reportable operating segments have been determined in accordance with the Company's internal management structure, which is organized based on operating activities, the manner in which we organize segments for making operating decisions and assessing performance and the availability of separate financial results. We do not allocate certain corporate expenses related to executive retirement plans, the Company’s Board of Directors and strategic initiatives, as well as certain other costs and report them in Corporate. Our former segments, Industrial and Widia, were combined into one Metal Cutting segment as of July 1, 2020. Infrastructure remains unchanged. Segment results have been retrospectively restated to reflect the change in reportable segments. Our reportable operating segments do not represent the aggregation of two or more operating segments.
Sales to a single customer did not aggregate to five percent or more of total sales in 2021, 2020 and 2019.
METAL CUTTING The Metal Cutting segment develops and manufactures high performance tooling and metal cutting products and services and offers an assortment of standard and custom metal cutting solutions to diverse end markets, including aerospace, general engineering, energy and transportation.

Metal Cutting markets its products under the Kennametal®, WIDIA®, WIDIA Hanita® and WIDIA GTD® brands through its direct sales force, a network of independent and national distributors, integrated supplier channels and via the Internet. Application engineers and technicians are critical to the sales process and directly assist our customers with specified product design, selection, application and support.
INFRASTRUCTURE Our Infrastructure segment produces engineered tungsten carbide and ceramic components, earth-cutting tools, and advanced metallurgical powders, primarily for the energy, earthworks and general engineering end markets.
