FORWARD-LOOKING STATEMENTS
This Annual Report on Form 10-K includes "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. This Act provides a safe harbor for forward-looking statements to encourage companies to provide prospective information about themselves so long as they identify these statements as forward-looking and provide meaningful cautionary statements identifying important factors that could cause actual results to differ from the projected results. All statements other than statements of historical fact we make in this Annual Report on Form 10-K are forward-looking and address a variety of subjects including, for example, future sales and operating results; growth or contraction, and trends in the industries and markets in which CMC Materials, Inc. ("CMC'', "the Company'', "us'', "we'', or "our''), participates, such as the semiconductor, and oil and gas industries; the acquisition of, investment in, or collaboration with other entities, including the Company’s acquisition of KMG Chemicals, Inc. (“KMG”), and the expected benefits and synergies of such acquisitions; divestment or disposition, or cessation of investment in certain of the Company’s businesses; new product introductions; development of new products, technologies and markets; product performance; the financial conditions of the Company's customers; the competitive landscape that relates to the Company's business; the Company's supply chain; natural disasters; various economic or political factors and international or national events, including related to global public health crises such as the COVID-19 pandemic ("Pandemic"), and the enactment of trade sanctions, tariffs, or other similar matters; the generation, protection and acquisition of intellectual property, and litigation related to such intellectual property or third party intellectual property; environmental, health and safety laws and regulations, and related compliance; the operation of facilities by the Company; the Company's management; foreign exchange fluctuation; the Company's current or future tax rate, including the effects of changes to tax laws in the jurisdictions in which the company operates; cybersecurity threats; financing facilities and related debt, pay off or payment of principal and interest, and compliance with covenants and other terms; and, uses and investment of the Company's cash balance, including dividends and share repurchases, which may be suspended, terminated or modified at any time for any reason by the Company, based on a variety of factors. Statements that are not historical facts, including statements about CMC’s beliefs, plans and expectations, are forward-looking statements. Such statements are based on current expectations of CMC’s management and are subject to a number of factors and uncertainties, which could cause actual results to differ materially from those described in the forward-looking statements. Except as required by law, CMC undertakes no obligation to update forward-looking statements made by it to reflect new information, subsequent events or circumstances. The section entitled "Risk Factors" of this Annual Report on Form 10-K describes some, but not all, of the factors that could cause these differences.

PART I
ITEM 1. BUSINESS
OUR COMPANY
CMC Materials, Inc., which was incorporated in the state of Delaware in 1999, is a leading global supplier of consumable materials to semiconductor manufacturers and pipeline companies. We operate our business within two reportable segments: Electronic Materials and Performance Materials.
RECENT DEVELOPMENTS
Effective October 1, 2020, the Company changed its name from “Cabot Microelectronics Corporation” to “CMC Materials, Inc.” Our new name reflects our expanded product offerings and industries in which we participate following our acquisition of KMG in fiscal 2019 (the “Acquisition”).
We completed the Acquisition on November 15, 2018 (“Acquisition Date”), and since then we have included the results of KMG, which produces and distributes specialty chemicals and performance materials for the semiconductor industry, pipeline and adjacent industries, and industrial wood preservation industry, in our consolidated results. For additional information, refer to Note 4 of “Notes to the Consolidated Financial Statements” included in Item 8 of Part II of this Annual Report on Form 10-K.
In the fourth quarter of fiscal 2019, we made a decision to close KMG-Bernuth, Inc.’s (“KMG-Bernuth”) Matamoros, Mexico and Tuscaloosa, Alabama wood treatment facilities and cease participating in the wood treatment business by approximately the end of calendar year 2021, and focus our strategy and future capital investments on our core businesses. Leading up to the planned closure of the Matamoros and Tuscaloosa facilities, we intend to continue to operate the existing facilities and serve our wood treatment customers. For additional information, refer to Note 10 of “Notes to the Consolidated Financial Statements” included in Item 8 of Part II of this Annual Report on Form 10-K.
ELECTRONIC MATERIALS SEGMENT
The Electronic Materials segment consists of our chemical mechanical planarization (“CMP”) slurries business, CMP polishing pads business, and our electronic chemicals business. These businesses supply consumable products used in integrated circuit (“IC”) device manufacturing and other aspects of the semiconductor and data storage industries.
IC devices, or "chips", are components in a wide range of electronic systems for computing, communications, manufacturing and transportation. The multi-step manufacturing process for IC devices typically begins with a circular wafer of pure silicon, then undergoes a process of alternating insulating and conducting layers until the desired wiring within the IC device is achieved. At the conclusion of the process, the wafer is cut into the individual IC devices, which are then packaged to form individual chips. Consumers most frequently encounter IC devices in smart phones and tablets, desktop or laptop computers, automotive applications, gaming devices, and televisions.
CMP SLURRIES AND CMP PADS
The Company develops, produces, and sells CMP slurries for polishing a wide range of materials used in IC devices, including tungsten, dielectric materials, copper, tantalum (commonly referred to as "barrier"), and aluminum, and for polishing bare silicon wafers, as well as disk substrates and magnetic heads used in hard disk drives. We also develop, manufacture, and sell CMP polishing pads, which are used in conjunction with slurries in the CMP process. Our CMP pads can be used on a variety of polishing tools and wafers, over a range of technology nodes and applications, including tungsten, copper, and dielectrics.
CMP slurries and pads (“CMP consumables”) are used to remove excess material that is deposited during the IC manufacturing process and to level and smooth the surfaces of the layers of IC devices via a combination of chemical reactions and mechanical abrasion, leaving minimal residue and defects on the surface, with only the material necessary for circuit integrity remaining. CMP enables IC device manufacturers to produce smaller, faster, and more complex IC with a greater density of transistors. CMP also helps reduce the number of defective or substandard IC devices, which increases the device yield. An effective CMP process is achieved through technical optimization of the CMP consumables in conjunction with an appropriately designed CMP process and generally requires slurries and pads to be qualified in its processes through an extensive series of tests and evaluations. While this qualification process varies depending on numerous factors, it is generally quite costly and may take six months or longer to complete. IC device manufacturers usually assess quality, cost, time required, and impact on production when they consider implementing or switching to a new CMP slurry or pad.

INDEX
ELECTRONIC CHEMICALS
In our electronic chemicals business, we offer semiconductor-grade wet chemicals with purities that extend to the parts-per-trillion (ppt) level. We produce and sell high-purity process chemicals through the formulation, purification, and blending of acids, solvents, and other wet chemicals primarily used to etch, clean, and dry silicon wafers during the production of semiconductors, photovoltaics (solar cells), and flat panel displays.
Our electronic chemicals products include sulfuric, phosphoric, nitric and hydrofluoric acids, ammonium hydroxide, hydrogen peroxide, isopropyl alcohol, other specialty organic solvents and various blends of chemicals. As the IC manufacturing process moves to more advanced technology nodes and the complexity of the process continues to increase, quality and purity of the materials becomes even more critical to the device yield. Increasing levels of purity and achieving lower levels of variation in our electronic chemicals business are required to enable next-generation IC technologies. Our advanced chemical purification technologies, including distillation, ion exchange, gas adsorption, and filtration, are designed to provide consistently low contaminant levels in a variety of high-purity process chemicals. We continue to work to develop industry-leading metrology and analytical methods to measure the purity levels achieved.
STRATEGY
Technology and innovation are vital to our Electronic Materials business, and we devote significant resources to research and development. We believe our focused effort on advanced technologies with technology-leading customers enables us to provide more compelling new products as semiconductor devices continue to advance. We focus our research and development activity to deliver innovative consumable products for advanced applications for our technology-leading customers. We have strategically located our research and development and clean room facilities, manufacturing operations, and related quality, field application, technical and customer support teams to be responsive to our customers' needs, which we believe provides us with a competitive advantage.
We also focus on building close relationships with our customers. We collaborate with them to identify and deliver new and improved solutions, to integrate our products into their manufacturing processes, and to assist them with supply, warehouse and inventory management.
We believe another competitive advantage is product and supply chain quality. Our customers demand continuous improvement in our products, in terms of product performance, quality and consistency. In pursuit of this, we work to continuously improve and innovate with respect to our own products, and as part of that, we require our raw materials suppliers, who provide us with certain important elements of our CMP slurries, pads and electronic chemicals, to do the same. We believe our capabilities in supply chain management and quality systems differentiate us from our competitors, and that our worldwide CMP consumables manufacturing plants and global network of suppliers also provide supply chain flexibility as needed. In our electronic chemicals business, we are responsible for product performance, purity levels and analytical testing, and in our view, our ability to maintain high quality levels and superior supply chain process is a competitive advantage.
INDUSTRY TRENDS
SEMICONDUCTOR INDUSTRY
Demand within the semiconductor industry is driven by smart phones, tablets, personal computers (“PCs”), servers, and a wide range of other electronic applications, including high-performance computing and artificial intelligence. Over time, overall semiconductor industry demand has fluctuated as a result of numerous factors, including the changing mix of demand drivers, semiconductor fab utilization, pressure to reduce costs, and the pace of technology advancement.
Over the past several years there has been a significant shift in semiconductor industry demand from IC devices for PCs to hand-held consumer electronic devices. Future demand for advanced semiconductor devices is expected to be driven by applications such as high performance computing, virtual and augmented reality, artificial intelligence, and 5G; demand for greater connectivity with wearables, peripherals, the internet of things, and increased semiconductor content in automobiles. While demand conditions may fluctuate, we continue to believe that semiconductor industry demand will grow over the long term based on increased usage of IC devices in existing applications, as seen in fiscal 2020 due to increased technology needs and renewed demand for PC’s due to “work from home” and remote learning as a result of the Pandemic, as well as future applications.

INDEX
Over the past several years, we have seen consolidation in the customer base within the semiconductor industry. Costs to achieve the required scale in manufacturing within the semiconductor industry continue to rise, along with the related costs of research and development, and larger manufacturers generally have greater access to the resources necessary to manage their businesses.
As demand for more advanced and lower cost electronic devices grows, there is ongoing pressure on IC device manufacturers to reduce their costs. Manufacturers have historically reduced cost and simultaneously improved device performance by migrating to smaller technology nodes. To achieve performance and cost improvements, semiconductor manufacturers are placing greater emphasis on new device architectures, including 3D memory and FinFET. Many manufacturers reduce costs by pursuing ever-increasing scale in their operations, while seeking to reduce their production costs by increasing their production yields regardless of their scale. However, as the industry continues to shrink dimensions, leading edge technology node transitions are becoming more challenging due to technical and physical obstacles, and the pace of technology change has slowed. Thus, they look for semiconductor materials products, such as CMP consumables and electronic chemicals, to help enable the achievement of technology progression with quality and performance attributes that can help them achieve their overall performance targets, cost structure, and to drive yield improvement.
DEMAND
Demand for our CMP consumables and electronic chemicals products reflects semiconductor industry demand patterns in terms of growth, cyclicality and seasonality, and varying demand for specific device types. Consistent with other participants in the semiconductor industry, we experienced relatively stable demand conditions in our fiscal 2020 despite global macroeconomic uncertainty caused by the Pandemic. Over the long term, we anticipate worldwide demand for CMP consumables and electronic chemicals used by IC device manufacturers to grow as a result of expected long-term growth in wafer starts, and the trend to more advanced technologies. With respect to CMP consumables, we believe there will continue to be an associated increase in the number of CMP polishing steps required to produce these advanced devices, and the introduction of new materials that are expected to require CMP. With respect to electronic chemicals, we believe there will be increasing demand as customers are transitioning to advanced technology nodes, which require an increasing number of processing steps used on each wafer and materials with higher purity levels.
COMPETITION
We compete in the semiconductor industry, which is characterized by technology advances, demanding requirements for product quality and consistency, and lower cost of ownership. We face competition from other suppliers of electronic materials. We believe we are the leading global supplier of CMP slurries, with a broad range of innovative solutions. Our CMP slurry competitors range from small companies that compete with a single product or in a single geographic region, to divisions of global companies with multiple lines of CMP products. With respect to CMP polishing pads, DuPont has held the leading position in this area for many years. Several other companies also participate in CMP consumables.
For our electronic chemicals business, there are various competitors with whom we compete in different regions. In North America, these include Honeywell, Kanto Corporation and Avantor. Outside the United States (U.S.), other providers in Europe are BASF, Technic and Honeywell, and in Asia, BASF and Kanto Corporation, among others. We believe our business in Europe is comparable to other providers, and other than in Singapore, at present we do not participate materially in the business in Asia.
CUSTOMERS, SALES, AND MARKETING
Within the semiconductor industry, our customers are generally producers of logic or memory IC devices, or providers of IC foundry services. Some logic customers, and so-called "fabless" companies, outsource some or all the production of their devices to foundries, which provide contract manufacturing services, in order to avoid the high cost of process development, construction and operation of a fab, or to provide additional capacity when needed.
We market our products primarily through direct sales to our customers, although we use distributors in certain areas. We believe this strategy of primarily direct sales provides us an additional means to collaborate closely with our customers and provides our customers with the most efficient means by which to procure our products. As part of our sales process, our logistics and sales personnel provide supply, warehouse and inventory management services for our customers.
For additional information on our customers, refer to Note 2 of “Notes to the Consolidated Financial Statements” included in Item 8 of Part II of this Annual Report on Form 10-K.

INDEX
RESEARCH, DEVELOPMENT AND TECHNICAL
As technology advances and semiconductor materials and designs increase in complexity, these challenges require significant investments in research, development and technical support (“R&D”), and we plan to continue to devote significant resources to R&D, and balance our efforts between shorter and longer-term industry needs.
Our global R&D team includes experts from the semiconductor industry and scientists and engineers from key disciplines required for the development of high-performance CMP consumable products. We operate CMP consumable product R&D facilities primarily in the U.S., with certain development capabilities in Taiwan and South Korea, in Singapore for data storage, and in Japan for silicon wafer products. We also operate electronic chemicals product development facilities in the U.S., Europe, and Singapore.
RAW MATERIALS SUPPLY
Engineered abrasive particles are significant raw materials we use in many of our CMP slurries. Our strategy is to secure various sources of different raw materials, as appropriate, to enable the desired performance of our products, and monitor those sources as necessary to provide supply assurance. We have multi-year supply agreements with several suppliers for the purchase of raw materials in the interest of supply and quality assurance, and to control costs.
In our electronic chemicals business, we rely on a variety of suppliers for our raw materials, some of which we purchase pursuant to purchase orders, and others which we purchase under supply contracts. The number of suppliers is often limited, particularly as to the specific grade of raw material required by us to supply high purity products to our customers.
PERFORMANCE MATERIALS SEGMENT
Our Performance Materials segment includes our pipeline and industrial materials (“PIM”) business, wood treatment business, and precision optics business. We are a leading global provider of products, services, and solutions for optimizing pipeline throughput and maximizing performance and safety. Our PIM products include drag-reducing agents (“DRAs”), valve greases, cleaners and sealants, and related equipment supporting pipeline and adjacent industries. We also provide routine and emergency maintenance services as well as training for customers in the pipeline and adjacent industries worldwide. Through QED Technologies International, Inc. (“QED”), our precision optics business, we serve the precision optics industry with capital equipment, consumables, and services. KMG-Bernuth operates the wood treatment business, which manufactures and sells wood treatment preservatives made from pentachlorophenol (“penta”).

INDEX
QED
Demand for products produced by QED is typically driven by the trends in the underlying industries that utilize precision optics, such as semiconductor equipment, aerospace, defense, research, biomedical, and digital imaging. Since our primary QED business is the sale of capital equipment, our results are typically affected by levels of capital spending in these industries. Historically, capital spending is cyclical, and is impacted by general macroeconomic conditions, government spending and policies, as well as industry-specific trends and dynamics.
COMPETITION
In our PIM business, LiquidPower Specialty Products Inc. holds a leading position in DRAs, with Baker Hughes as another primary provider. For our additional PIM products and services, however, participants include numerous other businesses with none appearing to hold a leadership position.
In QED, there are few direct competitors but we believe our technology is unique and provides a competitive advantage to customers in the precision optics industry, which still relies heavily on traditional artisanal methods of fabrication.
In our wood treatment business, we are the only manufacturer of penta-based wood treatment preservatives in North America.
CUSTOMERS, SALES, AND MARKETING
PIM PRODUCTS AND SERVICES
We provide DRAs to several major mid-stream pipeline transmission companies both domestically and internationally. We have a U.S.-based sales network, a U.S.-based transportation and logistics operations, and a global network of distributors and agents to manage the sales and delivery of our products. For our additional PIM products and services, we market and sell to pipeline and adjacent industry customers, such as service companies, and major utility distribution companies via direct sales and channel partners.

INDEX
ITEM 1A. RISK FACTORS
RISKS RELATING TO OUR BUSINESS, STRATEGY AND OPERATIONS
OUR BUSINESS AND RESULTS OF OPERATIONS MAY BE ADVERSELY AFFECTED BY THE CORONAVIRUS (COVID-19) PANDEMIC AND RELATED ADVERSE IMPACT TO WORLDWIDE ECONOMIC AND INDUSTRY CONDITIONS
The global spread of the Pandemic has created significant volatility, uncertainty and economic disruption across the world and in the countries and locations in which we and our customers and suppliers operate. In our third and fourth fiscal quarters of 2020, businesses in our Electronic Materials segment remained generally stable despite the Pandemic. With respect to our Performance Materials segment, the Pandemic had a significant adverse impact on our Performance Materials’ PIM business in our third and fourth fiscal quarters of 2020, as the demand for DRAs declined significantly due to the ongoing dislocation in the energy sector occasioned by the Pandemic as well as certain geopolitical factors, as described below. The extent to which the Pandemic may further impact our business, operations, results of operations and financial condition is uncertain and difficult to estimate, and depends on numerous evolving factors that we may not be able to accurately predict, which may include: A decrease in short-term and long-term demand and pricing for our products and services, and an ongoing global economic recession that could further reduce demand and/or pricing for our products and services resulting from actions taken by governments, businesses, or the general public in an effort to limit exposure to and spread of such infectious diseases, such as ongoing or renewed travel restrictions, quarantines, and business shutdowns or slowdowns; Negative impacts to our operations, including reductions in production levels, R&D activities, and qualification activities with our customers, and increased costs resulting from our efforts to mitigate the impact of the Pandemic through additional or continued social-distancing measures we have enacted at our locations around the world in an effort to protect our employees’ health and well-being (including working from home, reducing the number of employees or others in our sites at any one time and how such individuals perform work while at our sites, redesigning or adjusting our manufacturing, R&D and office facilities, and suspending or limiting employee travel); Deterioration of worldwide credit and financial markets that could limit our ability to obtain external financing to fund our operations and capital expenditures, result in losses on our holdings of cash and investments due to failures of financial institutions and other parties, and result in losses on our accounts receivables due to credit defaults or our customers’ inability to pay; and, Disruptions to our supply chain in connection with the sourcing of materials, equipment and logistics or other services and support necessary to our business as a result of the Pandemic and efforts to contain the spread of the Pandemic. To the extent possible if and when the Pandemic is contained or abates, the resumption of what was previously considered normal business operations after such interruption may be delayed or constrained by lingering effects of the Pandemic on our Company and our customers, suppliers, and third-party service providers. These effects, alone or taken together, could have a material adverse effect on our business, results of operations, legal exposure, or financial condition. A further sustained or prolonged outbreak or return of the Pandemic in the places in which we do business, such as is currently being experienced in the U.S. and Europe, could exacerbate the adverse impact of such measures on our Company.

INDEX
DEMAND FOR OUR PRODUCTS FLUCTUATES AND OUR BUSINESS MAY BE ADVERSELY AFFECTED BY WORLDWIDE ECONOMIC, INDUSTRY AND OTHER CONDITIONS
Our business is affected by economic and industry conditions, such as those currently being adversely affected by the Pandemic, and the majority of our revenue derives from our Electronic Materials segment, which is primarily dependent upon semiconductor industry demand. With respect to our Electronic Materials segment, historically, semiconductor industry demand has fluctuated due to economic and industry cycles and seasonal shifts in demand, which can affect our business, causing demand for our electronic materials products to fluctuate. For example, prior to the Pandemic, the relatively soft demand conditions in the semiconductor industry that had commenced in our second fiscal quarter of 2019 and continued into our first fiscal quarter of 2020 had begun to ameliorate in the beginning of the second fiscal quarter of 2020. However, although our Electronic Materials segment experienced relatively stable conditions during the third and fourth fiscal quarters of 2020, the ongoing nature of the Pandemic has created uncertainty as to demand conditions for the semiconductor industry going forward into our fiscal 2021 and beyond. Furthermore, competitive dynamics within the semiconductor industry may impact our business. Our limited visibility to future customer orders makes it difficult for us to predict industry trends, especially during unusual adverse circumstances, such as the Pandemic. If the global economy or the semiconductor industry weakens further, whether in general or as a result of the Pandemic or other specific factors, such as macroeconomic factors, or unpredictable events such as natural disasters, geopolitical conditions and international trade tensions, civil unrest, or additional global health crises, we could experience material adverse impacts on our results of operations and financial condition. Some additional factors that may affect demand for our electronic materials products include: demand trends for different types of electronic devices, such as logic versus memory IC devices, or digital versus analog IC devices; the various technology nodes at which those products are manufactured; customers' efficiencies in the use of CMP consumables and/or high-purity process chemicals (“electronic chemicals”); customers' device architectures and specific manufacturing processes; the short order to delivery time for our products; quarter-to-quarter changes in customer order patterns; market share and competitive gains and losses; and pricing changes by us and our competitors.
As to our Performance Materials segment, which continues to be an area of potential continued growth for us over the longer term, our PIM business may be impacted by changes in the utilities and/or oil and gas industries, such as we saw in our third and fourth fiscal quarters of 2020 resulting from ongoing significant dislocation in these industries occasioned by geopolitical disputes such as those that commenced in March 2020 between the Organization of Petroleum Exporting Countries ("OPEC") and Russia, and a confluence of an excess in oil capacity due to these factors and the ongoing Pandemic and efforts to contain the Pandemic. Relatedly, as described, volatility in oil and natural gas prices may impact our customers’ activity levels, including production, and as we saw during the third and fourth fiscal quarters of 2020, we experienced a significant drop in demand for our related PIM products and services. Expectations about future prices and price volatility are important in determining future spending levels for customers of our PIM products and services. The ongoing volatility in worldwide oil and natural gas prices and markets are an extreme example of historical volatility in this sector, and such volatility is likely to continue in the future. As is currently the case, prices for oil and natural gas are subject to wide fluctuations in response to relatively minor or major changes in the supply of and demand for oil and natural gas, market uncertainty and a variety of additional factors that are beyond our control. These factors include, but are not limited to, decreases or increases in supplies from U.S. shale production or other oil production, geopolitical conditions, including uprisings, civil unrest, and international trade tensions, sovereign debt crises, the domestic and foreign supply of oil and natural gas, the level of consumer demand due to economic growth or contraction such as currently seen related to the Pandemic, and other factors in countries such as China, weather conditions, domestic and foreign governmental regulations and taxes, the price and availability of alternative fuels, the health of international economic and credit markets, the ability of the members of the OPEC and other state-controlled oil companies to agree upon and maintain oil price and production controls, and general economic conditions, such as those currently seen related to the Pandemic.
Further, adverse global economic, industry and other conditions such as those related to the ongoing Pandemic could have other negative effects on our Company. For instance, we could experience negative impacts on cash flows due to the inability of our customers to pay their obligations to us, or our production processes could be harmed if our suppliers cannot fulfill their obligations to us. As a result of these or other conditions, we also might have to reduce the carrying value of goodwill and other intangible assets, which could harm our financial position and results of operations.

INDEX
WE MAY PURSUE ACQUISITIONS OF, INVESTMENTS IN, AND MERGERS OR STRATEGIC ALLIANCES WITH OTHER ENTITIES, WHICH COULD DISRUPT OUR OPERATIONS AND HARM OUR OPERATING RESULTS IF THEY ARE UNSUCCESSFUL, OR WE MAY ENCOUNTER UNANTICIPATED ISSUES IN IMPLEMENTING THEM
We expect to continue to make investments in technologies, assets and companies, either through acquisitions, mergers, investments or alliances, in order to supplement our organic growth and development efforts. Acquisitions, mergers, and investments, including our acquisitions of KMG, which we completed in November 2018, involve numerous risks, including the following: difficulties and risks in integrating the operations, technologies, products and personnel of acquired companies; difficulties and risks from unanticipated issues arising subsequent to a transaction related to the other entity; potential disruption of relationships with third parties such as customers or suppliers; diversion of management's attention from normal daily operations of the business; increased risk associated with foreign operations; potential difficulties and risks in entering markets or industries in which we have limited or no direct prior experience and/or where competitors have stronger positions; potential difficulties and unexpected situations arising in operating new businesses with different business models; facilities and operations; potential difficulties with regulatory or contract compliance in areas in which we have limited or no experience; initial dependence on unfamiliar supply chains or relatively small supply partners; insufficient revenue to offset increased expenses associated with acquisitions; potential loss of key employees of the acquired companies; or inability to effectively cooperate and collaborate with our alliance partners.
Further, we may never realize the perceived or anticipated benefits of a business combination or merger with, or asset or other acquisition of, or investments in, other entities. Transactions such as the Acquisition could and in some cases have had negative effects on our results of operations, in areas such as contingent liabilities, gross margins, amortization charges related to intangible assets and other effects of accounting for the purchases of other business entities. Investments in and acquisitions of technology-related or early-stage companies or assets are inherently risky because these businesses or assets may never develop, and we may incur losses related to these investments.
In addition, we may be required to impair the carrying value of these acquisitions or investments to reflect other than temporary declines in their value. The carrying value of goodwill represents the fair value of acquired businesses in excess of identifiable assets and liabilities as of the acquisition date. The carrying value of other intangible assets represents the fair value of customer relationships, tradenames and other acquired intangible assets as of the acquisition date. Goodwill and other acquired intangible assets expected to contribute indefinitely to our cash flows are not amortized, but must be evaluated for impairment by management at least annually. If the carrying value exceeds the implied fair value of goodwill, the goodwill is considered impaired and is reduced to fair value via a non-cash charge to earnings. If the carrying value of an indefinite-lived intangible asset is greater than its fair value, the intangible asset is considered impaired and is reduced to fair value via a non-cash charge to earnings. If the value of goodwill or other acquired intangible assets is impaired, our results of operations and financial condition could be adversely affected. Examples of asset impairment charges we recently incurred include the charge we took in the fourth quarter of fiscal 2019 and the fourth quarter of fiscal 2020 related to the KMG wood treatment business. Absent a sale of the wood treatment business, as we approach the previously announced closure date of the wood treatment facilities and there are fewer estimated future cash flows, we expect that the carrying value of the wood treatment asset group will not be recoverable, resulting in future impairments of intangible assets and goodwill. The amount of such impairments could be material and could adversely affect our results of operations and financial condition. See Notes 9 and 10 of “Notes to the Consolidated Financial Statements” included in Item 8 of Part II of this Annual Report on Form 10-K for additional discussion.
Furthermore, the integration of the acquired businesses into our operations is a complex and time-consuming process that may not be successful. Our Company has a limited history of integrating significant acquisitions, and the process of integration may produce unforeseen operating difficulties and expenditures. As demonstrated in the Acquisition, the primary areas of focus for successfully combining those businesses with our operations may include and have included, among others: retaining and integrating key employees; realizing synergies; aligning customer and supplier interfaces, and operations across the combined business; integrating enterprise resource planning and other information technology systems; and, managing the growth of the combined company. Even if we successfully integrate an acquired business, such as KMG, into our operations, there can be no assurance that we will realize the anticipated benefits of the Acquisition.
13

INDEX
WE HAVE A CONCENTRATED PRODUCT RANGE WITHIN EACH OF OUR SEGMENTS AND OUR PRODUCTS MAY BECOME OBSOLETE, OR TECHNOLOGICAL CHANGES MAY REDUCE OR LIMIT INCREASES IN THE CONSUMPTION OF OUR PRODUCTS
Although our product offerings expanded with the Acquisition, our business remains substantially dependent on products in our Electronic Materials segment, such as CMP slurries, pads and electronic chemicals, which account for the majority of our revenue. We have identified our Performance Materials segment as another area of potential continued growth and the product offerings in our Performance Materials segment are similarly concentrated. As such, our business would suffer if these products became obsolete or if consumption of these products decreased. Our success depends on our ability to keep pace with technological changes and advances in the industries in which we operate, particularly the semiconductor industry, and to adapt, improve and customize our products in response to evolving customer needs and industry trends. Since its inception, the semiconductor industry, which is the largest industry in which we operate, has experienced technological changes and advances in the design, manufacture, performance and application of IC devices. Our customers continually pursue lower cost of ownership and higher quality and performance of materials consumed in their manufacturing processes, including CMP slurries and pads and electronic chemicals, as a means to reduce costs, increase the yield in their manufacturing facilities, and achieve desired performance of the IC devices they produce. We expect these technological changes, and this drive toward lower costs, higher quality and performance and higher yields, will continue in the future. Potential technology developments in the semiconductor industry, as well as our customers' efforts to reduce consumption of CMP consumables, including through use of smaller quantities, could render our products less important to the IC device manufacturing process.
A SIGNIFICANT AMOUNT OF OUR BUSINESS COMES FROM A LIMITED NUMBER OF LARGE CUSTOMERS AND OUR REVENUE AND PROFITS COULD DECREASE SIGNIFICANTLY IF WE LOST ONE OR MORE OF THESE CUSTOMERS OR BUSINESS FROM THEM
Our customer base is concentrated among a limited number of large customers in each of our segments. Currently, our principal business is to supply electronic materials primarily to the semiconductor industry. The semiconductor industry has been consolidating as the larger semiconductor manufacturers have generally grown faster than the smaller ones, through business gains, mergers and acquisitions, and strategic alliances. Industry analysts predict that this trend will continue, which means the semiconductor industry will continue to be comprised of fewer and larger participants in the future if their prediction is correct. In addition, our customer base in our pipeline-related businesses is also somewhat concentrated, with large entities predominant, and outside of the U.S., these entities frequently are state-owned or sponsored, and limited in number per country. One or more of these principal customers could stop buying products from us or could substantially reduce the quantity of products purchased from us. Our principal customers in both of our segments also hold considerable purchasing power, which can impact the pricing and terms of sale of our products. Any deferral or significant reduction in the quantity or price of products sold to these principal customers could seriously harm our business, financial condition and results of operations.
ANY PROBLEM OR DISRUPTION IN OUR SUPPLY CHAIN, INCLUDING SUPPLY OF OUR MOST IMPORTANT RAW MATERIALS, OR IN OUR ABILITY TO MANUFACTURE OR DELIVER OUR PRODUCTS TO OUR CUSTOMERS, COULD ADVERSELY AFFECT OUR RESULTS OF OPERATIONS
We depend on our supply chain to enable us to meet the demands of our customers. Our supply chain includes the raw materials we use to manufacture our products, our production operations and the means by which we deliver our products to our customers. Our business could be adversely affected by any problem or interruption in the supply of the key raw materials we use in our products, including raw materials that do not meet the stringent quality and consistency requirements of our customers, any problem or interruption that may occur during production or delivery of our products, such as weather-related problems, natural disasters, global public health crises such as the ongoing Pandemic, geopolitical, trade or labor-related issues, civil unrest, or any difficulty in producing sufficient quantities of our products to meet growing demand from our customers. In particular, severe weather conditions have the potential to adversely affect our operations, damage facilities and increase our costs, and those conditions may also have an indirect effect on our operations by disrupting services provided by service companies or suppliers with whom we have a business relationship. Additionally, some of our full-time employees are represented by labor unions, works councils or comparable organizations, particularly in Mexico and Europe. An extended work stoppage, slowdown or other action by our employees could significantly disrupt our business. As our current agreements with labor unions and works councils expire, we cannot provide assurance that new agreements will be reached at the end of each period without union action, or that a new agreement will be reached on terms satisfactory to us. Future labor contracts may be on terms that result in higher labor costs to us, which also could adversely affect our results of operations. Our supply chain may also be negatively impacted by unanticipated price increases due to supply restrictions beyond the control of our Company or our raw materials suppliers, such as those related to the Pandemic.
14

We believe it would be difficult to promptly secure alternative sources of key raw materials in the event one of our suppliers becomes unable to supply us with sufficient quantities of raw materials that meet the quality and technical specifications required by us and our customers. In addition, new contract terms, forced production or manufacturing changes, contractual amendments to existing agreements with, or non-performance by, our suppliers, including any significant financial distress our suppliers may suffer, could adversely affect us. Also, if we change the supplier or type of key raw materials we use to make our products, in particular our electronic materials products, or are required to purchase them from a different manufacturer or manufacturing facility or otherwise modify our products, in certain circumstances our customers might have to requalify our products for their manufacturing processes and products. The requalification process could take a significant amount of time and expense to complete and could occupy technical resources of our customers that might otherwise be used to evaluate our new products, thus delaying potential revenue growth, or motivate our customers to consider purchasing products from our competitors, possibly interrupting or reducing our sales of products to these customers, especially sales of our electronic materials products to our semiconductor industry customers, but also with respect to our PIM products to our pipeline and adjacent industry customers.
OUR BUSINESS COULD BE SERIOUSLY HARMED IF OUR COMPETITORS DEVELOP COMPETITIVE PRODUCTS, OFFER BETTER PRICING, SERVICE OR OTHER TERMS, OR OBTAIN OR ASSERT CERTAIN INTELLECTUAL PROPERTY RIGHTS
Competition from other electronic materials or performance materials manufacturers or any new entrants could seriously harm our business and results of operations, and this competition could continue to increase. Competition has and will likely continue to impact the prices we are able to charge for our products, as well as our overall business. In addition, our competitors could have, obtain or assert intellectual property rights that could affect or restrict our ability to market our existing products and/or to innovate and develop new products, thus increasing our costs of doing business, could attempt to introduce products similar to ours following the expiration of our patents, or could attempt to introduce products that do not fall within the scope of our intellectual property rights.
WE ARE SUBJECT TO RISKS ASSOCIATED WITH OUR INTERNATIONAL OPERATIONS
We currently have operations and a large customer base outside the U.S. Approximately 65% of our revenue was generated by sales to customers outside the U.S. for the fiscal year ended September 30, 2020. We may encounter risks in doing business in certain countries other than the U.S., including, but not limited to, adverse changes in economic and political conditions, both in foreign locations and in the U.S. with respect to non-U.S. operations of U.S. businesses like ours, geopolitical and/or trade tensions, global health crises such as the ongoing Pandemic, civil unrest, fluctuation in exchange rates, changes in international trade requirements and sanctions and/or tariffs that affect our business and that of our customers and suppliers, compliance with a variety of foreign laws and regulations and related audits and investigations, as well as difficulty in enforcing business and customer contracts and agreements, including protection of intellectual property rights. We also may encounter risks that we may not be able to repatriate additional earnings from our operations outside of the U.S., derive anticipated tax benefits of these operations or recover the investments made in them, whether due to regulatory or policy changes in the U.S. or in the countries outside of the U.S. in which we do business, or other factors.
In particular, China continues to be an important market for the semiconductor industry, and an area of continued potential growth for us. As business between China and the rest of the world has continued to grow, there is risk that geopolitical, regulatory, trade, political and global public health crises such as the Pandemic could adversely affect business for companies like ours based on the complex relationships among China, the U.S., and other countries in the Asia Pacific region or elsewhere, which could have a material adverse impact on our business. In addition, there are risks that the Chinese government may, among other things, require the use of local suppliers, compel companies that do business in China to partner with local companies to conduct business, or, provide incentives to government-backed local customers to buy from local suppliers rather than companies like ours, all of which could adversely impact our business, including our results of operations. Also, as has been seen over our last fiscal year, there are risks that the U.S. government may impose additional export restrictions on technology and products that companies that operate in the semiconductor industry supply or use in China, which could adversely impact our business and our results of operations.
In addition, we have operations and customers located in the United Kingdom, which recently has exited the European Union (“EU”). Although the United Kingdom and the EU have agreed to operate under transitional provisions under which most EU law would remain in force in the United Kingdom until the end of December 2020, it is at present unclear as to what trade agreement the parties will operate under following such time, and what impacts such might have on our business.
15

LEGAL, COMPLIANCE AND REGULATORY RISKS
WE ARE SUBJECT TO EXTENSIVE ENVIRONMENTAL LAWS AND REGULATIONS AND MAY INCUR COSTS THAT HAVE AN ADVERSE EFFECT ON OUR FINANCIAL CONDITION AS A RESULT OF VIOLATIONS OF OR LIABILITIES UNDER THEM
Like other companies involved in environmentally sensitive businesses, our operations and properties are subject to extensive and stringent federal, state, local and foreign EHS laws and regulations, including those concerning, among other things:
•    the marketing, sale, use and registration of our chemical products, such as penta, which is part of the wood treatment business in our Performance Materials segment;
•    the treatment, storage and disposal of wastes;
•    the investigation and remediation of contaminated media including but not limited to soil and groundwater;
•    the discharge of effluents into waterways;
•    the emission of substances into the air; and
•    other matters relating to environmental protection and various health and safety matters.
The United States Environmental Protection Agency (“EPA”) and other federal and state agencies in the U.S., as well as comparable agencies in other countries where we have facilities or sell our products, such as Canada or Mexico, have the authority to promulgate regulations that could have a material adverse impact on our operations. These EHS laws and regulations may require permits for certain types of operations, require the installation of expensive pollution control equipment, place restrictions upon operations or impose substantial liability for pollution and other EHS concerns resulting from our operations. Compliance with EHS laws and regulations has resulted in ongoing costs for us and could restrict our ability to modify or expand our facilities, continue production, require us to install costly pollution control equipment, or incur significant other expenses, including environmental compliance costs. We continue to manage environmental compliance activities at certain sites, such as at KMG-Bernuth's Tuscaloosa, Alabama facility as described in Note 20 of “Notes to the Consolidated Financial Statements” included in Item 8 of Part II of this Annual Report on Form 10-K. We have incurred, and expect to continue to incur, significant costs to comply with EHS laws or to address liabilities for contamination resulting from past or present operations. Federal, state and foreign governmental authorities may seek fines and penalties, as well as injunctive relief, for violation of EHS laws and regulations, and could, among other things, impose liability on us to cleanup or mitigate environmental, natural resources or other damages resulting from a release of pesticides, hazardous materials or other chemicals into the environment. We maintain insurance coverage for sudden and accidental environmental damages. We do not believe that insurance coverage for environmental damage that occurs over time is available at a reasonable cost. Also, we do not believe that insurance coverage for the full potential liability that could be caused by sudden and accidental incidences is available at a reasonable cost. Accordingly, we may be subject to an uninsured or under-insured loss in such cases; although unknown at present, the KMG-Bernuth warehouse fire described in Note 20 of this Annual Report on Form 10-K may be such an instance.
The distribution, sale and use of our products is subject to prior governmental approvals and thereafter ongoing governmental regulation: Our products are subject to laws administered by federal, state and foreign governments, including regulations requiring registration, approval and labeling. The labeling requirements restrict the use and type of application for our products. More stringent restrictions could make our products less desirable which would adversely affect our sales and profitability. All venues where our penta products are used also require registration prior to marketing or use.
Governmental regulatory authorities have required, and may require in the future, that certain scientific testing and data production be provided on our products. Under the Federal Insecticide, Fungicide and Rodenticide Act (“FIFRA”), the EPA requires registrants to submit a wide range of scientific data to support U.S. registrations. This requirement significantly increases our Operating expenses, and we expect those expenses will continue in the future while we operate the wood treatment business. Because scientific analyses are constantly improving, we cannot determine with certainty whether or not new or additional tests may be required by regulatory authorities. While good laboratory practice standards specify the minimum practices and procedures that must be followed in order to ensure the quality and integrity of data related to these tests submitted to the EPA, there can be no assurance that the EPA will not request certain tests or studies be repeated. In addition, more stringent legislation or requirements may be imposed in the future. Amendments to the Toxic Substances Control Act could result in increased regulation and required testing of chemicals we manufacture and could increase the costs of compliance for our operations. We can provide no assurance that the cost of such compliance will not adversely affect our profitability. Our products could also be subject to other future regulatory action that may result in restricting or completely banning their use which could have an adverse effect on our performance and results of operations.

16

1. The Registration, Evaluation and Authorization of Chemicals (“REACH”) legislation may affect our ability to manufacture and sell certain products in the EU: REACH requires chemical manufacturers and importers in the EU to prove the safety of their products. We were required to pre-register certain products and file comprehensive reports, including testing data, on each chemical substance, and perform chemical safety assessments. Additionally, substances of high concern are subject to an authorization process. Authorization may result in restrictions on certain uses of products or even prohibitions on the manufacture or importation of products. The full registration requirements of REACH have been phased in over several years, and we have incurred additional expense to cause the registration of our products under these regulations. REACH may also affect our ability to import, manufacture and sell certain products in the EU. In addition, other countries and regions of the world already have or may adopt legislation similar to REACH that affect our business, affect our ability to import, manufacture or sell certain products in these jurisdictions, and have required or will require us to incur increased costs.
2. The classification of penta as a Persistent Organic Pollutant (“POP”) under the Stockholm Convention may adversely affect our ability to manufacture or sell our penta products: The Conference of the Parties (“COP”) accepted the recommendation of the United Nations Persistent Organic Pollutant Review Committee that the use of penta should be banned except that its use for the treatment of utility poles and crossarms could continue for an extended period of five to ten years. KMG-Bernuth supplies penta to industrial customers who use it primarily to treat utility poles and crossarms. The U.S. is not bound by the determination of the COP because it did not ratify the Stockholm Convention treaty. Canada and Mexico are governed by the treaty. KMG-Bernuth's sole penta manufacturing facility is located in Matamoros, Mexico, and its processing facility is located in Tuscaloosa, Alabama. As a result of the classification of penta as a POP, the Mexican government requires KMG-Bernuth to cease producing penta in Mexico by the end of calendar year 2021. In July 2020, the Canadian government released a proposed order that sales and use of penta in Canada be ceased, but such proposed order is subject to a comment period and is not final, and no timing for any such order, if implemented, has been proposed. In October 2020, the EPA indicated it was inclined to issue a proposed order that provided alternatives, one similar to Canada’s proposed order and one that would provide reregistration according to certain additional occupational use parameters to those currently existing, but any such proposed order would be subject to a comment period, including with respect to the second alternative, would be expected to provide a transition period intended not to disrupt customers of penta. In July 2019, KMG-Bernuth had communicated plans to close both the Matamoros and Tuscaloosa facilities by the end of calendar year 2021 and to consolidate into and build a new facility. However, in November 2019, we communicated that we will not build a new facility, and that while we intend to explore various options for the wood treatment business we did not intend to continue the business past approximately the end of calendar year 2021. We took a restructuring charge and asset impairment charges in our fourth fiscal quarter of 2019 related to the decision to close the Matamoros and Tuscaloosa facilities and to not build a new plant, and as described further in Note 10 of this Annual Report on Form 10-K, we have taken an additional impairment charge in our fourth fiscal quarter of 2020 and expect to take additional impairment charges related to the wood treatment business through the end of calendar year 2021. No assurance can be given that we will not incur significant expenditures in connection with closing the facilities, or that the ultimate action of the COP and our related decisions will not adversely impact on our financial condition and results of operation.
3. If our products are not re-registered by the EPA or are re-registered subject to new restrictions, our ability to sell our products may be curtailed or significantly limited: as described above, KMG-Bernuth's penta product registrations are under continuous review by the EPA under FIFRA. The failure of KMG-Bernuth's products to be re-registered, to satisfy the registration review by the EPA, or the imposition of new use, labeling or other restrictions in connection with re-registration could have an adverse effect on our financial condition and results of operations.
4. Our use of hazardous materials exposes us to potential liabilities: Our manufacturing and distribution of chemical products, such as our electronic chemicals, involves the controlled use of hazardous materials. Our operations, therefore, are subject to various associated risks, including chemical spills, discharges or releases of toxic or hazardous substances or gases, fires, mechanical failure, storage facility leaks and similar events. Our suppliers are subject to similar risks that may adversely impact the availability of raw materials. While we adapt our manufacturing and distribution processes to the environmental control standards of regulatory authorities, we cannot completely eliminate the risk of accidental contamination or injury from hazardous or regulated materials, including injury of our employees, individuals who handle our products or goods treated with our products, or others who claim to have been exposed to our products, nor can we completely eliminate the unanticipated interruption or suspension of operations at our facilities due to such events. We may be held liable for significant damages or fines in the event of contamination or injury, and such assessed damages or fines could have an adverse effect on our financial performance and results of operations.
17

CURRENT OR FUTURE CLIMATE CHANGE REGULATIONS COULD RESULT IN INCREASED OPERATING COSTS AND REDUCED DEMAND FOR OUR PRODUCTS
The U.S. has notified the United Nations of its intention to withdraw from the Paris Climate Agreement and to date, has not ratified the Kyoto Protocol. The Clean Air Act has been interpreted to regulate greenhouse gas (“GHG”) emissions and the EPA is using its existing regulatory authority to develop regulations requiring reduction in GHG emissions from various categories of sources, such as when a permit is required due to emissions of other pollutants. Because of the lack of any comprehensive legislation program addressing GHGs, a number of U.S. federal laws related to GHG emissions have been considered by the U.S. Congress from time to time and various state, local and regional regulations and initiatives have been enacted or are being considered related to GHGs.
Member States of the EU each have an overall cap on emissions, which are approved by the European Commission, and implement the EU Emissions Trading Directive as a commitment to the Kyoto Protocol. GHG emissions are regulated by Member States through the EU Emission Trading System and the EU Effort Sharing Decision/Regulation depending upon the industry sector. Organizations apply to the Member State for an allowance of GHG emissions. These allowances are tradable so as to enable companies that manage to reduce their GHG emissions to sell their excess allowances to companies that are not reaching their emissions objectives. Failure to purchase sufficient allowances will require the purchase of allowances at a current market price.
Any laws or regulations that may be adopted to restrict or reduce emissions of GHGs could cause an increase to our raw material costs, require us to incur increased operating costs, and have an adverse effect on demand for our products and our financial performance and results for our business.
In addition to GHG and climate change regulatory developments and legislation, we are continuing to evaluate and assess the potential impact on our business of the ongoing transition worldwide to a low carbon, resilient economy as well as physical effects resulting from climate change.
OUR PRODUCTS MAY BE RENDERED OBSOLETE OR LESS ATTRACTIVE BY CHANGES IN INDUSTRY REQUIREMENTS OR BY SUPPLY-CHAIN DRIVEN PRESSURES TO SHIFT TO ENVIRONMENTALLY PREFERABLE ALTERNATIVES
Changes in regulatory, legislative and industry requirements, or changes driven by supply-chain pressures, may shift current customers away from products using penta, products containing hazardous materials, or certain of our other products and toward alternative products that are believed to have fewer environmental effects. The EPA, foreign and state regulators, local governments, private environmental advocacy organizations, investors and investor advisory firms, and a number of large industrial companies have proposed or adopted policies designed to decrease the use of a variety of chemicals, including penta and others included in certain of our products, such as those containing hazardous materials. Our ability to anticipate changes in regulatory, legislative, investor and industry requirements, or changes driven by supply-chain pressures, affects our ability to remain competitive. Further, we may not be able to comply with changed or new regulatory or industrial standards that may be necessary for us to remain competitive.
We cannot assure you that the EPA, foreign and state regulators or local governments will not restrict the uses of penta or certain of our other products or ban the use of one or more of these products or the raw materials in them. Similarly, companies who use our products may decide to reduce significantly or cease the use of our products voluntarily. As a result, our products may become obsolete or less attractive to our customers.
18

GENERAL COMMERCIAL, OPERATIONAL, FINANCIAL AND REGULATORY RISKS
BECAUSE WE RELY ON OUR INTELLECTUAL PROPERTY, OUR FAILURE TO ADEQUATELY OBTAIN OR PROTECT IT COULD SIGNIFICANTLY HARM OUR BUSINESS
Protection of intellectual property is particularly important in the semiconductor industry, which is the primary industry in which we participate, because we develop complex technical formulas and processes for products that are proprietary in nature and differentiate our products from those of our competitors. Our intellectual property is important to our success and ability to compete. We attempt to protect our intellectual property rights through a combination of patent, trademark, copyright and trade secret laws, as well as employee and third-party nondisclosure and assignment agreements. In addition, we protect our product differentiation through various other means, such as proprietary supply arrangements for certain raw materials, and use of certain manufacturing technologies. Due to our international operations, we pursue protection in different jurisdictions, which may provide varying degrees of protection, and we cannot provide assurance that we can obtain adequate protection in each such jurisdiction. Our failure to obtain or maintain adequate protection of our intellectual property rights for any reason, including through the patent prosecution process or in the event of litigation related to such intellectual property, which we pursue when necessary to protect our rights against others who are found to be misusing our intellectual property, could seriously harm our business. In addition, certain types of intellectual property, such as patents, expire after a certain period of time, and products protected by our patents then lose such protection, so we refresh our intellectual property portfolio on an ongoing basis through continued innovation, and failure to do so could adversely affect our business. Also, the costs of obtaining or protecting our intellectual property could negatively affect our operating results.
OUR INABILITY TO ATTRACT AND RETAIN KEY PERSONNEL COULD CAUSE OUR BUSINESS TO SUFFER
We utilize and rely upon a global workforce. If we fail to attract and retain the necessary managerial, technical and customer support personnel, our business and our ability to maintain existing and obtain new customers, develop new products and provide acceptable levels of customer service could suffer. We compete worldwide with other participants in the industries in which we do business for qualified personnel, particularly those with significant experience in the semiconductor and pipeline industries. The loss of services of key employees, or our inability to obtain or maintain visas or other travel or residency documents on their behalf with respect to our business needs, could harm our business and results of operations. Periodically, we engage in succession planning for our key employees, and our Board of Directors reviews succession planning for our executive officers, including our chief executive officer, on an annual basis.
BECAUSE WE HAVE LIMITED EXPERIENCE IN BUSINESS AREAS OUTSIDE OF ELECTRONIC MATERIALS AND PERFORMANCE MATERIALS, EXPANSION OF OUR BUSINESS INTO OTHER PRODUCTS AND APPLICATIONS MAY NOT BE SUCCESSFUL
An element of our strategy has been to leverage our customer relationships, technological expertise and other capabilities and competencies to expand our business. For example, we have made acquisitions to expand beyond CMP consumables into other electronic materials product areas, as well as into performance materials product areas in which we have limited experience. Expanding our business into new product areas could involve technologies, production processes and business models in which we have limited experience, and we may not be able to develop and produce products or provide services that satisfy customers' needs, or we may be unable to keep pace with technological or other developments. Or, we may decide that we no longer wish to pursue these new business initiatives. Also, our competitors may have or obtain intellectual property rights that could restrict our ability to market our existing products and/or to innovate and develop new products.
TAX INCREASES OR CHANGES IN TAX RULES MAY ADVERSELY AFFECT OUR FINANCIAL RESULTS
As a company conducting business on a global basis, we are exposed, both directly and indirectly, to effects of changes in U.S., state, local and foreign tax rules. In December 2017, comprehensive tax legislation was enacted in the U.S. under the Tax Cuts and Jobs Act (the “Tax Act”). Known and certain estimated effects based upon current interpretation of the Tax Act have been incorporated into our financial results. Adjustments to income tax amounts could be material to our results of operations and cash flows. In addition, there is a risk that state or foreign jurisdictions may amend their tax laws, whether in response to the Tax Act or otherwise, which could have a material impact on our future results of operations and cash flows.
19

CERTAIN CRITICAL INFORMATION SYSTEMS COULD BE SUSCEPTIBLE TO CYBERSECURITY AND OTHER THREATS
We maintain and rely upon certain critical information systems for the effective operation of our business. These information systems include, but are not limited to, telecommunications, the Internet, our corporate intranet, various computer hardware and software applications, network communications, and email. These information systems may be owned and maintained by us, our outsourced providers, or third parties such as vendors, contractors, and Cloud providers. All these information systems are subject to disruption, breach or failure from various sources including, but not limited to, attacks, degradation, and failures resulting from potential sources, including viruses, malware, denial of service, destructive or inadequate code, power failures, and physical damage. Confidential and/or sensitive information stored on these information systems, or transmitted to or from Cloud storage, could be intentionally or unintentionally compromised, lost, and/or stolen. While we have implemented security procedures and virus protection software, intrusion prevention systems, access control, and emergency recovery processes to mitigate risks like these with respect to information systems that are under our control, they are not fail-safe and may be subject to breaches. Further, we cannot assure that third parties upon whom we rely for various IT services will maintain sufficient vigilance and controls over their systems. Our inability to use or access these information systems at critical points in time, or unauthorized releases of personal or confidential information, could unfavorably impact the timely and efficient operation of our business, including our results of operations, and our reputation, as well as our relationships with our employees or other individuals whose information may have been affected by such cybersecurity incidents.
In addition, regulatory authorities have increased their focus on how companies collect, process, use, store, share and transmit personal data. Privacy security laws and regulations, including the United Kingdom's Data Protection Act 2018 and the EU General Data Protection Regulation 2016, and similar laws in countries such as Korea and Taiwan, among others, pose increasingly complex compliance challenges, which may increase compliance costs, and any failure to comply with data privacy laws and regulations could result in significant penalties that could adversely affect our business and results of operations.
OUR ABILITY TO RAISE CAPITAL IN THE FUTURE MAY BE LIMITED, WHICH COULD PREVENT US FROM GROWING, AND OUR EXISTING CREDIT AGREEMENT COULD RESTRICT OUR BUSINESS ACTIVITIES
In the future we may be required to raise capital through public or private financing or other arrangements. Such financing may not be available on acceptable terms, or at all, and our failure to raise capital when needed could harm our business. During the first quarter of fiscal 2020, the Company amended its credit agreement ("Amended Credit Agreement") to reduce the interest rate on term loan borrowings, under the Senior Secured Term Loan Facility under the Amended Credit Agreement ("Term Loan Facility"). Our Amended Credit Agreement contains financial and other covenants that may restrict our business activities or our ability to execute our strategic objectives, and our failure to comply with these covenants could result in a default under it. Furthermore, additional equity financing may dilute the interests of our common stockholders, and debt financing, if available, may involve restrictive covenants that could further restrict our business activities or our ability to execute our strategic objectives and could reduce our profitability. If we raise or borrow funds on acceptable terms, we may not be able to grow our business or respond to competitive pressures.
In addition, borrowings under our Amended Credit Agreement generally bear interest based on (a) a London Inter-bank Offered Rate (“LIBOR”), subject to a 0.00% floor, or (b) a base rate, in each case plus an applicable margin of, in the case of borrowings under the Term Loan Facility, 2.00% for LIBOR loans and 1.00% for base rate loans and, in the case of borrowings under the Amended Credit Agreement's revolving credit facility ("Revolving Credit Facility"), initially, 1.50% for LIBOR loans and 0.50% for base rate loans. On July 27, 2017, the Financial Conduct Authority (the authority that regulates LIBOR) announced that it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. In the U.S., the Alternative Reference Rates Committee, the working group formed to recommend an alternative rate to LIBOR, has identified the Secured Overnight Financing Rate as its preferred alternative rate for USD LIBOR. When LIBOR ceases to exist after 2021, any calculation of interest based upon the Alternate Base Rate (or any comparable or replacement formulation), may result in higher interest rates. To the extent that these interest rates increase, our Interest expense will increase, which could adversely affect our financial condition, operating results and cash flows.

THE MARKET PRICE FOR OUR COMMON STOCK MAY FLUCTUATE SIGNIFICANTLY AND RAPIDLY
The market price of our common stock has fluctuated and could continue to fluctuate significantly as a result of factors such as: economic, geopolitical, global public health, political and stock market conditions generally and specifically as they may impact participants in the semiconductor and related industries; and/or participants in oil and gas related industries; changes in financial estimates and recommendations by securities analysts who follow our stock; earnings and other announcements, and changes in market evaluations, by securities analysts, investors, market participants or others, of or related to, us or participants in the semiconductor and related industries; changes in business, trade or regulatory conditions affecting us or participants in the semiconductor and related industries; announcements or implementation by us, our competitors, or our customers of technological innovations, new products or different business strategies; changes in our capital deployment strategy, issuances of shares of our capital stock or entering into a business combination or other strategic transaction; and trading volume of our common stock. This has been evident since approximately March of 2020 in the wake of the significant adverse impact to global economic conditions of the Pandemic and also dislocation in the oil and gas sector.
ANTI-TAKEOVER PROVISIONS UNDER OUR CERTIFICATE OF INCORPORATION AND BYLAWS MAY DISCOURAGE THIRD PARTIES FROM MAKING AN UNSOLICITED BID FOR OUR COMPANY
Our certificate of incorporation and bylaws, and various provisions of the Delaware General Corporation Law may make it more difficult or expensive to effect a change in control of our Company. For instance, our amended and restated certificate of incorporation provides for the division of our Board of Directors into three classes as nearly equal in size as possible with staggered three-year terms.
We have adopted change in control arrangements covering our executive officers and other key employees. These arrangements provide for a cash severance payment, continued medical benefits and other ancillary payments and benefits upon termination of service of a covered employee's employment following a change in control, which may make it more expensive to acquire our Company.

ITEM 1B. UNRESOLVED STAFF COMMENTS
None.

ITEM 2. PROPERTIES
Our global headquarters and research and development facilities are located in Aurora, Illinois. As of September 30, 2020, we operated 46 facilities globally, of which 20 facilities are owned by the company and 26 are leased. The Company operates in 18 facilities located in the U.S. and 28 are outside the U.S. These facilities outside the Unites States include locations in Taiwan, Japan, South Korea, Singapore, China, Canada, Mexico, Italy, France, and the United Kingdom.
We believe that our facilities are suitable and adequate for their intended purpose and provide us with sufficient capacity and capacity expansion opportunities and technological capability to meet our current and expected demand in the foreseeable future. We intend to expand certain of our facilities to meet our anticipated business needs.

ITEM 3. LEGAL PROCEEDINGS
We periodically become a party to legal proceedings, arbitrations, regulatory proceedings, inquiries and investigations (“contingencies”) arising in the ordinary course of our business operations. The ultimate resolution of these contingencies is subject to significant uncertainty, and should we fail to prevail in any of them or should several of them be resolved against us in the same reporting period, these matters could, individually or in the aggregate, be material to our consolidated financial statements. The information set forth in Note 20 of “Notes to the Consolidated Financial Statements” included in Item 8 of Part II of this Annual Report on Form 10-K is incorporated by reference into this Item 3.

ITEM 4. MINE SAFETY DISCLOSURES
Not applicable.

PART II
ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES
Our common stock is listed on the NASDAQ Global Select Market under the symbol “CCMP.” As of October 31, 2020, there were approximately 598 holders of record of our common stock. In January 2016, we announced that our Board of Directors authorized the initiation of a regular dividend program under which the Company intends to pay quarterly cash dividends on our common stock. The declaration and payment of future dividends is subject to the discretion and determination of the Company's Board of Directors and management, based on a variety of factors, and the program may be suspended, terminated or modified at any time for any reason.
ISSUER PURCHASES OF EQUITY SECURITIES
In January 2016, our Board of Directors authorized an increase in the amount available under our share repurchase program from the previously remaining $75.0 million to $150.0 million. Under this program, we repurchased 318 thousand shares for $35.0 million in fiscal 2020. There were no share repurchases under the share repurchase program in the fourth quarter of 2020. As of September 30, 2020, $36.3 million remained available under our share repurchase program. The manner in which the Company repurchases its shares is discussed in Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, under the heading "Liquidity and Capital Resources", of this Annual Report on Form 10-K. To date, we have funded share purchases under our share repurchase program from our available cash balance, and currently anticipate we will continue to do so.
Separate from this share repurchase program, a total of 25 thousand shares were withheld from equity award recipients to cover payroll taxes on the vesting of shares of restricted stock or restricted stock units during fiscal 2020 pursuant to the terms of our 2012 Omnibus Incentive Plan, as amended (“OIP”).

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following "Management's Discussion and Analysis of Financial Condition and Results of Operations" (MD&A) should be read in conjunction with our historical financial statements and "Notes to the Consolidated Financial Statements," which are included in Item 8 of Part II of this Annual Report on Form 10-K. For management's discussion and analysis of our results of operations for fiscal 2019 as compared to fiscal 2018 please refer to Part II, Item 7 "Management's discussion and analysis of financial condition and results of operations" on Form 10-K for our fiscal year ended September 30, 2019, filed with the SEC on November 27, 2019, which is incorporated herein by reference.

OVERVIEW
CMC is a leading global supplier of consumable materials to semiconductor manufacturers and pipeline companies. The Company’s electronic materials products play a critical role in the production of advanced semiconductor devices, helping to enable the manufacture of smaller, faster and more complex devices by its customers. The Company’s PIM products and services provide solutions for optimizing pipeline throughput and maximizing performance and safety.
Recent Developments and Items Impacting Comparability
The Company completed the Acquisition on the Acquisition Date and the Consolidated Financial Statements included in this Annual Report on Form 10-K include the financial results of KMG since that date. For additional information, refer to Part 1, Item 1, “Business”, in this Annual Report on Form 10-K.
In the fourth quarter of fiscal 2019, we made a decision to close KMG-Bernuth’s Matamoros, Mexico and Tuscaloosa, Alabama wood treatment facilities and cease participating in the wood treatment business by approximately the end of calendar year 2021, and focus our strategy and future capital investments on our core businesses. Until the planned closure of the Matamoros and Tuscaloosa facilities, we intend to continue to operate the existing facilities and serve our wood treatment customers.
The global spread of the Pandemic has created significant uncertainty and economic disruption worldwide and in the countries and locations in which we and our customers and suppliers operate. Our primary focus has been and continues to be on the health and well-being of our employees and the ongoing operation of our facilities worldwide according to our business continuity plans, which we update on an ongoing basis.
To date, we have not seen a meaningful impact from the Pandemic on our ability to manufacture and deliver products to our customers, but the Pandemic has negatively impacted some of the industries we serve, primarily the oil and gas industry. The Pandemic has exacerbated the impact of the continued geopolitical factors within the oil and gas industry, resulting in lower demand for our PIM products. Demand from our semiconductor industry customers, which represents approximately 80% of our revenue, remained stable in our fourth fiscal quarter as the work-from-home and remote learning environments benefited certain areas such as cloud, PCs and servers, offsetting weakness in industrial and automotive sectors of the industry.
The extent to which the Pandemic may further impact our business, operations, results of operations and financial condition going forward is uncertain and difficult to estimate, and depends on numerous evolving and potentially unknown factors.

INDEX
YEAR ENDED SEPTEMBER 30, 2020, AS COMPARED TO YEAR ENDED SEPTEMBER 30, 2019
REVENUE
Revenue was $1,116.3 million in fiscal 2020, which represented an increase of 7.6%, or $78.6 million, from fiscal 2019. The increase in revenue was primarily driven by the Acquisition. The increase was primarily due to the addition of the KMG businesses for the full period in fiscal 2020, selected price increases, and increased revenue from CMP slurries, offset by lower revenue from CMP pads.
COST OF SALES
Total Cost of sales was $627.7 million in fiscal 2020, which represented an increase of 5.5%, or $32.6 million, from fiscal 2019. The increase was primarily due to addition of the KMG businesses for the full period in fiscal 2020.
GROSS MARGIN
Our gross margin was 43.8% in fiscal 2020 compared to 42.7% in fiscal 2019. The increase was primarily due to price increases for our wood treatment products.
SELLING, GENERAL AND ADMINISTRATIVE
Selling, general and administrative expenses were $217.1 million in fiscal 2020, which represented an increase of 1.9%, or $4.0 million, from fiscal 2019. This was primarily due to a $24.7 million increase in amortization expense associated with re-valuing KMG assets to fair value during fiscal 2019 and $3.3 million increase in staffing-related costs, including incentive compensation costs primarily resulting from higher expense from the Short-Term Incentive Program (“STIP”), our annual cash incentive program, partially offset by a $24.4 million decrease in Acquisition and integration related expenses, as well as a $3.3 million decrease in travel expenses.
ASSET IMPAIRMENT CHARGES
Asset impairment charges were $2.3 million in fiscal 2020 compared to $67.4 million in fiscal 2019 due to impairment of the long-lived assets and intangible assets in the wood treatment asset group as a result of the planned closure of its facilities. See Note 10 of “Notes to the Consolidated Financial Statements” included in Item 8 of Part II of this Annual Report on Form 10-K.
INTEREST EXPENSE
Interest expense was $42.5 million in fiscal 2020, which represented a decrease of $3.2 million, from fiscal 2019. The decrease was primarily due to a decline in the LIBOR rate for the unhedged portion of the Company's Term Loan Facility, a lower outstanding term loan balance due to repayments, and a lower interest rate on our borrowings resulting from the refinancing of our Amended Credit Agreement in the first quarter of fiscal 2020. The decrease was partially offset by the longer period of time during which the Term Loan Facility was outstanding within the twelve months ended September 30, 2020 compared to the twelve months ended September 30, 2019.
PROVISION FOR INCOME TAXES
Our effective income tax rate was 17.6% in fiscal 2020 compared to 37.9% in fiscal 2019. The decrease in the effective tax rate during fiscal 2020 was primarily due to the absence of a discrete charge recorded in fiscal 2019 related to the final regulations issued under the Tax Act and the absence of unfavorable tax treatment of certain non-deductible costs related to the Acquisition.
NET INCOME
Net income was $142.8 million in fiscal 2020, which represented an increase of 264.2%, or $103.6 million, from fiscal 2019.  Net income benefited from the addition of the KMG businesses for the full period in fiscal 2020, lower Acquisition and integration-related expenses, and lower Asset impairment charges related to the wood treatment business, partially offset by amortization associated with re-valuing KMG assets to fair value.

Performance Materials 45.7  % 44.6  % 110 bpts


ELECTRONIC MATERIALS

The $49.8 million increase in Electronic Materials revenue was driven by a full year of KMG’s electronic chemicals business post-Acquisition and increased sales volume of CMP slurries, partially offset by lower CMP pads sales. The $4.1 million increase in adjusted EBITDA for Electronic Materials was driven by the revenue increases, as well as stronger profitability in CMP slurries, partially offset by higher fixed manufacturing costs. The 150 basis points decrease in adjusted EBITDA margin was primarily due to product mix.

PERFORMANCE MATERIALS

The $28.8 million increase in Performance Materials revenue was driven by higher selling prices for our wood treatment products and a full year of KMG’s performance materials businesses post-Acquisition. The $15.4 million increase in Performance Materials adjusted EBITDA and 110 basis points increase in Performance Materials adjusted EBITDA margin were primarily driven by higher selling prices for wood treatment products.

USE OF CERTAIN GAAP AND NON-GAAP FINANCIAL INFORMATION
Certain financial measures contained in this Annual Report on Form 10-K adjust for the impact of specified items and are not calculated in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP” or “GAAP”). We provide certain non-GAAP financial measures, such as adjusted EBITDA and adjusted EBITDA margin, to complement reported GAAP results because we believe that analysis of our financial performance is enhanced by an understanding of these non-GAAP financial measures. We exclude certain items from earnings when presenting our adjusted EBITDA measure because we believe they will be incurred infrequently and/or are otherwise not indicative of the Company’s regular, ongoing operating performance. Accordingly, we believe that they aid in evaluating the underlying operational performance of our business, and facilitate comparisons between periods. In addition, adjusted EBITDA is used as one of the performance goals of our fiscal 2020 Short-Term Incentive Program. A similar adjusted EBITDA calculation is also used by our lenders for a key debt compliance ratio.

Adjusted EBITDA margin is defined as adjusted EBITDA as a percentage of revenue. Adjusted EBITDA is defined as earnings before interest, income taxes, depreciation and amortization, adjusted for certain items that affect comparability from period to period. These adjustments include items related to the Acquisition, such as expenses incurred to complete the Acquisition and integration related expenses, costs of restructuring and asset impairment related to the wood treatment business and related adjustments, costs related to the KMG-Bernuth warehouse fire net of insurance recovery, costs related to the Pandemic net of grants received, and impact of fair value adjustments to inventory acquired from KMG.

The non-GAAP financial measures provided are a supplement to, and not a substitute for, the Company’s financial results presented in accordance with U.S. GAAP. Management strongly encourages investors to review the Company’s consolidated financial statements in their entirety and to not rely on any single financial measure. A reconciliation table of GAAP to non-GAAP financial measures is contained below.

Adjusted EBITDA for the Electronic Materials and Performance Materials segments is presented in conformity with Accounting Standards Codification Topic 280, Segment Reporting. This measure is reported to the chief operating decision maker for purposes of making decisions about allocating resources to the segments and assessing their performance. For these reasons, this measure is excluded from the definition of non-GAAP financial measures under the SEC Regulation G and Item 10(e) of Regulation S-K.

LIQUIDITY AND CAPITAL RESOURCES
As of September 30, 2020, we had $257.4 million of cash and cash equivalents compared with $188.5 million as of September 30, 2019. On September 30, 2020, $159.4 million of cash and cash equivalents was held in foreign subsidiaries. Our total liquidity as of September 30, 2020 was $457.4 million compared to $388.5 million as of September 30, 2019 (including $200.0 million of borrowing availability under our Revolving Credit Facility in both periods, which includes our letter of credit sub-facility). The increase in liquidity reflects the cash flow provided by operating activities, partially offset by the cash used by additions of property, plant and equipment, the repurchases of our common stock, and payments of quarterly cash dividends.
Total debt, consisting of principal outstanding on our Term Loan Facility, amounted to $921.4 million ($936.4 million in aggregate principal amount less $14.9 million of debt issuance costs) as of September 30, 2020 and $941.8 million ($959.7 million in aggregate principal amount less $17.9 million of debt issuance costs) as of September 30, 2019.
In March 2020, the Company drew $150.0 million under the Revolving Credit Facility as a precautionary measure in order to increase its cash position and preserve financial flexibility in light of uncertain global economic conditions resulting from the Pandemic. In September 2020, the Company repaid the amount outstanding under the Revolving Credit Facility, which had been unused in full, and as of September 30, 2020, had no remaining balance outstanding under the Revolving Credit Facility.
The Revolving Credit Facility requires that the Company maintain a maximum first lien secured net leverage ratio, as defined in the Amended Credit Agreement, of 4.00 to 1.00 as of the last day of each fiscal quarter. As of September 30, 2020, our maximum first lien secured net leverage ratio was 1.81 to 1.00. Additionally, the Amended Credit Agreement contains certain affirmative and negative covenants that limit the ability of the Company, among other things and subject to certain significant exceptions, to incur debt or liens, make investments, enter into certain mergers, consolidations, asset sales and acquisitions, pay dividends and make other restricted payments and enter into transactions with affiliates. We believe we are in compliance with these covenants as of September 30, 2020 and we expect to remain in compliance with our debt covenants during fiscal 2021 and beyond.
In January 2016, our Board of Directors authorized an increase in the amount available under our share repurchase program to $150.0 million. In fiscal 2020, we repurchased 318 thousand shares under this program, and $36.3 million authorization remained at the end of the year. The timing, manner, price and amounts of repurchases are determined at the Company's discretion, and the share repurchase program may be suspended, terminated or modified at any time for any reason. The repurchase program does not obligate the Company to acquire any specific number of shares. To date, we have funded share purchases under our share repurchase program from our available cash on hand, and anticipate we will continue to do so.
Our Board of Directors authorized the initiation of our regular quarterly cash dividend program in January 2016, and since that time has increased the dividend to its current level of $0.44 per share.  The declaration and payment of future dividends is subject to the discretion and determination of the Board of Directors and management, based on a variety of factors, and the program may be suspended, terminated or modified at any time for any reason.
We believe that cash on hand, cash available from future operations, and available borrowing capacity under our Amended Credit Agreement will be sufficient to fund our operations, expected capital expenditures, dividend payments, and share repurchases for at least the next twelve months. However, the current macroeconomic dislocation caused by the Pandemic has created uncertainty in worldwide economic conditions and in those of the industries in which we participate, and whether with respect to the impact of the Pandemic or in pursuit of corporate development or other initiatives, we may need to raise additional funds in the future through equity or debt financing, or other arrangements.  Depending on future conditions in the capital and credit markets, we could encounter difficulty securing additional financing in the type or amount necessary to pursue these objectives.

Operating Activities
We generated $287.3 million in cash flows from operating activities in fiscal 2020, $175.0 million in fiscal 2019 and $168.9 million in fiscal 2018. Our cash provided by operating activities in fiscal 2020 reflected Net income of $142.8 million, $137.8 million in non-cash reconciling items, and decreases in working capital of $6.7 million. Non-cash reconciling items in fiscal 2020 included $127.7 million of depreciation and amortization expense, $16.4 million of share-based compensation expense, partially offset by $11.3 million of deferred income tax benefit. Our cash provided by operating activities in fiscal 2019 reflected Net income of $39.2 million and $175.2 million in non-cash reconciling items, partially offset by increases in working capital of $39.4 million. Non-cash reconciling items in fiscal 2019 included $98.6 million of depreciation and amortization expense, $67.4 million of wood treatment asset impairment charges, $18.2 million of share-based compensation expense, and $14.9 million of inventory step-up on acquired inventory sold, partially offset by $27.2 million of deferred income tax benefit. Our cash provided by operating activities in fiscal 2018 reflected Net income of $110.0 million and $66.8 million in non-cash reconciling items, partially offset by increases in working capital of $7.9 million. Non-cash reconciling items in fiscal 2018 included $25.9 million of depreciation and amortization expense, $18.5 million of share-based compensation expense, $11.3 million of deemed repatriation transition tax, and $10.8 million deferred income tax expense.
Investing Activities
In fiscal 2020, cash flows used in investing activities were $124.3, representing property, plant and equipment additions of $125.8 million, net of cash inflows of $1.6 million from the disposition of property. In fiscal 2019, cash flows used in investing activities were $1,233.0 million, representing property, plant and equipment additions of $56.0 million and $1,182.2 million used for the Acquisition, net of cash inflows of $5.2 million from insurance policies and disposition of property. The remainder of the Acquisition was satisfied with the issuance of common stock.  In fiscal 2018, cash flows used in investing activities were $22.8 million for purchases of property, plant and equipment.
Financing Activities
In fiscal 2020, cash flows used in financing activities were $97.7 million, which included $50.4 million of dividend payments, $38.2 million of cash used in stock repurchases, and $23.3 million of repayments on long-term debt. In fiscal 2019, cash flows provided from financing activities were $894.4 million. During the first quarter of fiscal 2019, we received $1,043.6 million in debt proceeds, net of $18.7 million in debt issuance costs and $2.7 million original discount fees, which was used for the Acquisition. This was partially offset by $105.3 million of repayments on this debt and $46.3 million of dividend payments during fiscal 2019. In fiscal 2018, cash used in financing activities were $197.6 million, which included $144.4 million of repayments on long-term debt, $30.7 million of dividend payments, and $44.3 million of cash used in stock repurchases.

OFF-BALANCE SHEET ARRANGEMENTS
At September 30, 2020 and 2019, we did not have any unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which might have been established for the purpose of facilitating off-balance sheet arrangements.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES
The Company’s accounting policies are more fully described in Note 2 of "Notes to the Consolidated Financial Statements" included in Part II, Item 8 of this Annual Report on Form 10-K of the Consolidated Financial Statements. As disclosed in Note 2, the preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingencies. Actual results may differ from these estimates under different assumptions or conditions. The Company believes that the following discussion addresses the Company’s most critical accounting policies, which are those that are most important to the portrayal of the Company’s financial condition and results of operations and require management’s most difficult, subjective and complex judgments.
GOODWILL AND OTHER INTANGIBLE ASSETS
We perform an annual impairment assessment of goodwill and other intangible assets at the reporting unit level as of September 30 of each year, or more frequently if circumstances indicate that the carrying value may not be recoverable. Where we use the qualitative assessment, we determine based on qualitative factors, such as macroeconomic, industry, legal, and financial performance, whether it is more likely than not that an impairment exists. If the qualitative assessment indicates that it is more likely than not that an impairment exists, then a quantitative assessment is performed.
Qualitative factors include industry and market considerations, overall financial performance, industry, legal and other relevant events and factors affecting the reporting unit. Additionally, as part of this assessment, we may perform a quantitative analysis to support the qualitative factors above by applying sensitivities to assumptions and inputs used in measuring a reporting unit’s fair value.
In our quantitative assessment, estimated fair value is determined using an average of a discounted cash flow model and a market approach based on earnings before interest, taxes, and depreciation for a group of guideline comparable companies. Factors requiring significant judgment include the selection of market comparable companies, projected future revenue and gross margin, discount rates, and terminal growth rates. The wood treatment reporting unit fair value is determined using the discounted cash flow model only. The use of different assumptions, estimates or judgments could significantly impact the estimated fair value of a reporting unit, and therefore, impact the excess fair value above carrying value of the reporting unit. The reporting unit’s carrying value used in an impairment test represents the assignment of various assets and liabilities, excluding certain corporate assets and liabilities, such as cash, investments, and debt.
We test the reasonableness of the inputs and outcomes of our discounted cash flow models against available market data. Two of the Company’s reporting units, wood treatment and PIM, are at risk of failing future impairment tests, as the September 30, 2020 estimates of fair value do not substantially exceed their carrying values. As previously announced, the Company is closing its wood treatment facilities by approximately the end of calendar year 2021. The fair value of the wood treatment asset group was sufficient such that the recognized impairment was limited to long-lived assets and the reporting unit goodwill was not impaired, however, as the Company approaches the closure date of the facilities and there are lower estimated future cash flows, the carrying value of the wood treatment asset group and reporting unit will not be recoverable, resulting in future impairments. The carrying value includes $35.0 million and $3.8 million of goodwill and intangible assets as of September 30, 2020, respectively. There is no excess fair value over the carrying value as of September 30, 2020.
For PIM, the estimated fair value of the reporting unit exceeded the carrying value by approximately 8%. PIM’s carrying value includes $318.2 million of goodwill and $46.0 million of trade-name intangible assets. Key assumptions in the goodwill test include projected future revenue and gross margin, a 10.5% discount rate, and a terminal growth rate of 3%. A 50 basis point change in the projected compound annual revenue growth rate, discount rate, or terminal growth assumption would not result in an impairment. The fair values for all other reporting units substantially exceeded their carrying value. Refer to Note 10 of “Notes to the Consolidated Financial Statements” included in Item 8 of Part II of this Annual Report on Form 10-K for more information regarding wood treatment.
The Flowchem LLC (“Flowchem”) trade name, an indefinite-lived intangible asset, was assessed for impairment using a relief from royalty approach. Factors requiring significant judgment include projected revenue, royalty rates, terminal growth rates, and discount rates.
Significant management judgment is required to estimate projected future revenue. All assumptions used in our impairment valuation for indefinite-lived intangible assets and goodwill are based on best available information and are consistent with internal forecasts and operating plans.

ACCOUNTING FOR INCOME TAXES
We are subject to income taxes in the U.S. and numerous foreign jurisdictions. Accordingly, the determination of our provision for income taxes requires judgment, the use of estimates in certain cases and the interpretation and application of complex tax laws. Our effective income tax rate is affected by many factors, including changes in our assessment of certain tax contingencies, increases and decreases in valuation allowances, changes in tax law, outcomes of audits, and the mix of earnings among our U.S. and international operations.
We assess whether or not our deferred tax assets will ultimately be realized, and record an estimated valuation allowance on those deferred tax assets that may not be realized. Many factors are considered when assessing whether it is more likely than not that the deferred tax assets will be realized, including recent cumulative earnings, expectations of future taxable income, carryforward periods and other relevant quantitative and qualitative factors. The recoverability of the deferred tax assets is evaluated by assessing the adequacy of future expected taxable income from all sources, including reversal of taxable temporary differences, forecasted operating earnings and available tax planning strategies. This evaluation is based on best available information and are consistent with internal forecasts and operating plans.
We recognize the tax benefit of an uncertain tax position only if it is more likely than not that the tax position will be sustained by the taxing authorities, based on the technical merits of the position. When facts and circumstances change, we reassess these probabilities and record any changes in the financial statements as appropriate. This determination requires the use of judgment in evaluating our tax positions and assessing the timing and amounts of deductible and taxable items. See Note 19 of "Notes to the Consolidated Financial Statements" included in Part II, Item 8 of this Annual Report on Form 10-K for additional information on income taxes.
EFFECTS OF RECENT ACCOUNTING PRONOUNCEMENTS
See Note 2 of "Notes to the Consolidated Financial Statements" included in Part II, Item 8 of this Annual Report on Form 10-K for a description of recent accounting pronouncements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
EFFECT OF CURRENCY EXCHANGE RATES AND EXCHANGE RATE RISK MANAGEMENT
We conduct business operations outside of the U.S. through our foreign operations. Most of our foreign operations maintain their accounting records in their local currencies. Consequently, period to period comparability of results of operations is affected by fluctuations in exchange rates. The primary currencies to which we have exposure are the Korean won, Japanese yen, the New Taiwan dollar, Euro, British pound, and Singapore dollar. Approximately 22% of our revenue is transacted in currencies other than the U.S. dollar. However, outside of the U.S., we also incur expenses that are transacted in currencies other than the U.S. dollar, which mitigates the exposure on the Consolidated Statements of Income. We periodically enter into forward contracts in an effort to manage foreign currency exchange exposure on our Consolidated Balance Sheets. However, we are unlikely to be able to hedge these exposures completely. We do not enter into forward contracts or other derivative instruments for speculative or trading purposes.
Currency fluctuations have not had a material impact on our Consolidated Statements of Income during fiscal years 2020, 2019 and 2018.  While currency fluctuations did not have a significant impact on other comprehensive income on our Consolidated Balance Sheets in fiscal 2018, they did have a significant impact in fiscal 2020 and 2019.  We recorded $19.3 million in currency translation gains and $8.5 million in currency translation losses, net of tax, during fiscal 2020 and 2019, respectively, which was included in other comprehensive income.
MARKET RISK AND SENSITIVITY ANALYSIS RELATED TO FOREIGN EXCHANGE RATE RISK
We have performed a sensitivity analysis assuming a hypothetical 10% additional adverse movement in foreign exchange rates.  As of September 30, 2020, the analysis demonstrated that such market movements would not have a material adverse effect on our consolidated financial position, results of operations or cash flows over a one-year period.  Actual gains and losses in the future may differ materially from this analysis based on changes in the timing and amount of foreign currency rate movements and our actual exposures.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Stockholders of CMC Materials, Inc.
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of CMC Materials, Inc. and its subsidiaries (the “Company”) as of September 30, 2020 and 2019, and the related consolidated statements of income, of comprehensive income (loss), of changes in stockholders' equity and of cash flows for each of the three years in the period ended September 30, 2020, 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 September 30, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of September 30, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended September 30, 2020 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of September 30, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Change in Accounting Principle
As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for leases as of October 1, 2019.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. 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
39

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.
Goodwill Impairment Assessment - Pipeline and Industrial Materials (“PIM”) and CMP Pads Reporting Units
As described in Notes 2 and 9 to the consolidated financial statements, the Company’s consolidated goodwill balance was $718.6 million at September 30, 2020, which included the PIM and CMP Pads reporting units. Goodwill is tested for impairment annually on September 30, or between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The goodwill impairment assessment is performed comparing the estimated fair value of the reporting units to their carrying amounts. Estimated fair values are determined using the average of a discounted cash flow model and a market approach based on earnings before interest, taxes, and depreciation for a group of guideline comparable companies. Factors requiring significant judgment include the selection of valuation approach and assumptions related to future revenue and gross margin, discount rates, and terminal growth rates.
The principal considerations for our determination that performing procedures relating to the goodwill impairment assessment of the PIM and CMP Pads reporting units is a critical audit matter are (i) the significant judgment by management when determining the fair value of the reporting units using the discounted cash flow models; (ii) the high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating the significant assumptions used in management’s fair value estimate related to future revenue, gross margin, terminal growth rate and the discount rate for the PIM reporting unit, and future revenue and gross margin for the CMP Pads reporting unit; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s goodwill impairment assessment, including controls over the valuation of the Company’s PIM and CMP Pads reporting units. These procedures also included, among others, testing management’s process for determining the fair value estimate of the PIM and CMP Pads reporting units; evaluating the appropriateness of using the average of a discounted cash flow model and a market approach based upon relevant market multiples; testing the completeness and accuracy of underlying data used in the discounted cash flow models; and evaluating the significant assumptions used by management related to future revenue, gross margin, terminal growth rate and the discount rate for the PIM reporting unit, and future revenue and gross margin for the CMP Pads reporting unit. Evaluating management’s assumptions related to future revenue, gross margin, and terminal growth rate involved evaluating whether the assumptions used were reasonable considering (i) the current and past performance of the reporting units, (ii) the consistency with external market and industry data, and (iii) whether these assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in the evaluation of the appropriateness of the discounted cash flow models and market approach and the reasonableness of the PIM discount rate assumption.

CMC MATERIALS, INC
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(In thousands, except per share amounts)
1. BACKGROUND AND BASIS OF PRESENTATION
On October 1, 2020, Cabot Microelectronics Corporation changed its name to CMC Materials, Inc. (“CMC”, “the Company”, “us”, “we”, or “our”'). CMC is a leading global supplier of consumable materials to semiconductor manufacturers and pipeline companies. The Company's products play a critical role in the production of advanced semiconductor devices, helping to enable the manufacture of smaller, faster and more complex devices by its customers. The Consolidated Financial Statements included in this Annual Report on Form 10-K include the financial results of KMG Chemicals, Inc. (“KMG”) since the Company’s acquisition of 100% of the outstanding stock of KMG (the “Acquisition”) on November 15, 2018 (the “Acquisition Date”).
Since the Acquisition, we operate our business within two reportable segments: Electronic Materials and Performance Materials. The Electronic Materials segment consists of our chemical mechanical planarization (“CMP”) slurries business, CMP pads business, and electronic chemicals business. The Performance Materials segment consists of our pipeline and industrial materials (“PIM”) business, wood treatment business and QED Technologies International, Inc. (“QED”) business.
The audited consolidated financial statements have been prepared by CMC pursuant to the rules of the Securities and Exchange Commission (“SEC”) and accounting principles generally accepted in the United States of America (“U.S. GAAP” or “GAAP”). 
In Note 19. Income Taxes of this Annual Report on Form 10-K, the presentation for the table with the reconciliation between the Federal statutory rate and the Provision for income taxes at our effective tax rate has been updated for the fiscal year’s 2019 and 2018 to conform to the current year’s presentation. The amounts for those fiscal years that related to a change in reserve position and included in “U.S. benefits from research and experimentation activities” and “Other, net” previously, are now presented separately under “Change in reserve positions.”

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
PRINCIPLES OF CONSOLIDATION
The Consolidated Financial Statements include the accounts of CMC Materials, Inc. and its subsidiaries. All intercompany transactions and balances between the companies have been eliminated.
USE OF ESTIMATES
The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires management to make judgments, assumptions and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience, current conditions, and on various other assumptions that we believe are reasonable under the circumstances. However, future events are subject to change and estimates and judgments routinely require adjustment.  Actual results may differ from these estimates under different assumptions or conditions.
CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
We consider investments in all highly liquid financial instruments with original maturities of three months or less to be cash equivalents. Short-term investments include securities generally having maturities of 90 days to one year. We did not own any securities that were considered short-term investments as of September 30, 2020 or 2019.
ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS
Trade accounts receivable are recorded at the invoiced amount and do not bear interest. We maintain an allowance for doubtful accounts for estimated losses resulting from the potential inability of our customers to make required payments. Our allowance for doubtful accounts is based on historical collection experience, adjusted for any specific known conditions or circumstances such as customer bankruptcies and increased risk due to economic conditions. Uncollectible account balances are charged against the allowance when we believe that it is probable that the receivable will not be recovered. Amounts charged to bad debt expense are recorded in Selling, general and administrative expenses.
48

Our allowance for doubtful accounts changed during the fiscal year ended September 30, 2020 and 2019 as follows:

2020 2019
Beginning Balance $ 2,377  $ 1,900 
Amount of charge (benefit) to expense (1,122) 432 
Deductions and adjustments (672) 45 
Ending Balance at September 30 $ 583  $ 2,377 
CONCENTRATION OF CREDIT RISK
Financial instruments that subject us to concentrations of credit risk consist principally of accounts receivable. We perform ongoing credit evaluations of our customers' financial conditions and generally do not require collateral to secure accounts receivable. Our exposure to credit risk associated with nonpayment is affected principally by conditions or occurrences within the semiconductor industry, pipeline and adjacent industries, and the global economy. We have not experienced significant losses relating to accounts receivable from individual customers or groups of customers.
Customers who represented more than 10% of consolidated revenue, all of which are in the Electronic Materials segment, are as follows:
Year Ended September 30,
2020 2019 2018
Intel 15  % 14  % *
Samsung Group (Samsung) 11  % 11  % 18  %
Taiwan Semiconductor Manufacturing Co. (TSMC) * * 12  %
SK Hynix Inc. * * 10  %
* Customer did not represent more than 10% of consolidated revenue.
Of those customers who represented more than 10% of consolidated revenue, their net accounts receivable as a percentage of total net accounts receivable are as follows:
September 30,
2020 2019
Intel 8.5  % 8.1  %
Samsung Group (Samsung) 7.0  % 5.5  %

FAIR VALUES OF FINANCIAL INSTRUMENTS
The recorded amounts of cash, accounts receivable, and accounts payable approximate their fair values due to their short-term, highly liquid characteristics. Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Financial Accounting Standards Board ("FASB") established a three-level hierarchy for disclosure based on the extent and level of judgment used to estimate fair value.  Level 1 inputs consist of valuations based on quoted market prices in active markets for identical assets or liabilities.  Level 2 inputs consist of valuations based on quoted prices for similar assets or liabilities, quoted prices for identical assets or liabilities in an inactive market, or other observable inputs.  Level 3 inputs consist of valuations based on unobservable inputs that are supported by little or no market activity.
INVENTORIES
Inventories are recorded on the first-in, first-out (FIFO) basis and are stated at the lower of cost or net realizable value. Finished goods and work in process inventories include material, labor and manufacturing overhead costs. We regularly review and write down the value of inventory as required for estimated obsolescence or lack of marketability. 
49

PROPERTY, PLANT AND EQUIPMENT
Property, plant and equipment are recorded at cost. Depreciation is based on the following estimated useful lives of the assets using the straight-line method:

Land Improvements
10-20 years
Buildings
15-30 years
Machinery and equipment
3-20 years
Furniture and fixtures
5-10 years
Vehicles
5-8 years
Information systems
3-5 years
Assets under financing leases The shorter of the term of the lease or estimated useful life
Expenditures for repairs and maintenance are charged to expense as incurred.
LEASES
Effective October 1, 2019, the Company adopted the new lease accounting guidance which requires the recognition of a right of use asset and a corresponding lease liability for operating leases. The Company applies provisions of the guidance to operating leases with terms of more than twelve months for all lease classes except for real estate leases for which the guidance is applied to all leases. Additionally, the Company elected to account for non-lease components and lease components together as a single lease component for all asset classes. The Company’s lease transactions primarily consist of leases for facilities, equipment, and vehicles under operating leases. The Company does not have any material finance leases. Certain of the Company’s leases have an option to extend the lease term and the renewal period is included in determining the lease term for leases where the renewal option is reasonably certain to be exercised.
The new standard was adopted in our first quarter of fiscal 2020 using the modified retrospective transition method; however, we applied the optional transition adjustment that permits us to continue applying Topic 840 within the comparative periods disclosed.
ASSET RETIREMENT OBLIGATIONS
Our asset retirement obligations (“AROs”) include reclamation requirements as regulated by government authorities or contractual obligations for the removal or storage of hazardous materials, decontamination or demolition of above ground storage tanks, and certain restoration and decommissioning obligations related to certain of our owned and leased properties. The Company recognizes an ARO in the period in which it is incurred, if a reasonable estimate can be made. The accounting for ARO requires estimates by management about when and how the assets will be retired, the cost of retirement obligations, discount and inflation rates used in determining fair values and the methods of remediation associated with our AROs. We generally use assumptions and estimates that reflect the most likely remediation method. Our estimated liability for AROs is revised annually, and whenever events or changes in circumstances indicate that a revision to the estimate is necessary.
In subsequent periods, the Company recognizes accretion expense in Cost of sales increasing the ARO balances, such that the balance will ultimately equal the expected cash flows at the time of settlement. AROs are included in Other long-term liabilities on the Consolidated Balance Sheets.
The Company has multiple production facilities with an indeterminate useful life and there is insufficient information available to estimate a range of potential settlement dates for the obligation. Therefore, the Company cannot reasonably estimate the fair value of the liability. When a reasonable estimate can be made, an asset retirement obligation will be recorded, and such amounts may be material to the consolidated financial statements in the period in which they are recorded.
IMPAIRMENT OF LONG-LIVED ASSETS
We assess the recoverability of the carrying value of long-lived assets to be held and used, whenever events or changes in circumstances indicate that the carrying value may not be recoverable. For purposes of recognition and measurement of an impairment loss, long-lived assets are either individually identified or grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. When a long-lived asset is considered impaired a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset.
50

GOODWILL AND OTHER INTANGIBLE ASSETS
Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in business combinations. Goodwill and Intangible assets that have indefinite lives are tested for impairment annually on September 30, or between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company’s reporting units are CMP slurries, CMP pads, electronic chemicals, PIM, wood treatment, and QED.
Intangible assets that have finite lives are amortized over their respective useful lives of 2 to 20 years. Intangible assets are tested for impairment if an event occurs or circumstances change that indicates the carrying value may not be recoverable.
For each reporting unit, the Company has the option to perform either the qualitative analysis ("step zero") or a quantitative analysis ("step one"). In the event a reporting unit fails the qualitative assessment, it is required to perform the quantitative test. The goodwill impairment assessment is performed by comparing the estimated fair value of the reporting units to their carrying amounts. Estimated fair values are determined using the average of a discounted cash flows model and a market approach based on earnings before interest, taxes, and depreciation for a group of guideline comparable companies. Factors requiring significant judgment include the selection of valuation approach and assumptions related to future revenue and gross margin, discount rates, and terminal growth rates. If the fair value of the reporting unit is less than its carrying value, the reporting unit will recognize an impairment for the lesser of either the amount by which the reporting unit's carrying amount exceeds the fair value of the reporting unit or the reporting unit’s goodwill carrying value. We used a step zero qualitative analysis for the CMP slurries reporting unit in fiscal 2018, 2019 and 2020, and for precision optics in fiscal 2019 and 2020. Aside from those previously noted, all other reporting units were assessed for goodwill impairment using a step one approach.
The Flowchem LLC (“Flowchem”) trade name, an indefinite-lived intangible asset, was assessed for impairment using a relief from royalty approach. Factors requiring significant judgment include projected revenue, royalty rates, terminal growth rates, and discount rates.
The Company provides disclosure of the potential risk of impairment when a reporting unit’s fair value exceeds its carrying value by less than ten percent.
REVENUE RECOGNITION
Performance Obligations and Material Rights
The Company recognizes revenue using the five-step process of 1) identifying the contract, 2) identifying the performance obligation within the contract, 3) determining the transaction price, 4) allocating the transaction price to the performance obligations, and 5) recognizing the revenue as the performance obligations are satisfied through the transfer of control. A majority of the Company’s contracts have a single performance obligation which represents, in most cases, the products, equipment or services being sold to the customer. Some contracts include delivery of free product that we have concluded represents a material right.
Contracts vary in length and payment terms vary depending on the products or services offered, however, the period of time between invoicing and when payment is due is typically not significant. As a result, we do not have significant financing components. Transaction price is determined upon establishment of the contract that contains the final terms of the sale, including the description, quantity, and price of goods or services purchased. In instances where we receive consideration from a customer prior to transferring goods or services to the customer under the terms of a sales contract, we record a contract liability until the performance obligation is satisfied. Contracts with prospective tiered price discounts require judgment in determining the transaction price. For sales contracts that contain multiple performance obligations, the Company allocates the transaction price to each performance obligation identified in the contract based on relative standalone selling prices or estimates of such prices. When we invoice for products shipped under contracts with multiple performance obligations, we defer a portion of the revenue associated with the material rights on the balance sheet as a contract liability.
The Company recognizes revenue related to product sales at a point in time following the transfer of control of such products to the customer, which generally occurs upon shipment, or delivery depending on the terms of the underlying contracts. Revenue is recognized on consignment sales when control transfers to the customer, generally at the point of customer usage of the product. For services provided to customers in the pipeline and adjacent industries, including preventive maintenance, repair, and specialized isolation sealing on pipelines and training, revenue is recorded at a point in time when the services are completed as this is when right to payment and customer acceptance occurs.
51

Costs to Obtain and Fulfill a Contract
For certain contracts within the Performance Materials segment, commissions are paid to sales agents based upon a percentage of end-customer invoice value after funds are received by the Company from its customers. As a practical expedient, the Company does not capitalize commissions as the associated contracts are generally one year or less in duration. For shipping and handling activities performed after a customer obtains control of the goods, the Company has elected to account for these costs as activities to fulfill the promise to transfer the goods and included in Cost of sales.
RESEARCH, DEVELOPMENT AND TECHNICAL
Research, development and technical costs are expensed as incurred and consist primarily of staffing costs, materials and supplies, depreciation, utilities and other facilities costs.
LEGAL COSTS
Legal costs are expensed as incurred.
INCOME TAXES
Current income taxes are determined based on estimated taxes payable or refundable on tax returns for the current year. Deferred income taxes are determined using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. The effect on deferred tax assets and liabilities of changes in tax rates is recognized in income in the period that includes the enactment date. Provisions are made for both U.S. and any foreign deferred income tax liability or benefit. We assess whether or not our deferred tax assets will ultimately be realized and record an estimated valuation allowance on those deferred tax assets that may not be realized. We recognize the tax benefit of an uncertain tax position only if it is more likely than not that the tax position will be sustained by the taxing authorities, based on the technical merits of the position.
The Company recognizes interest and penalties related to unrecognized tax benefits within the Provision for income taxes. Accrued interest and penalties are included in Other long-term liabilities.
DERIVATIVES AND HEDGING
The Company is exposed to various market risks, including risks associated with interest rates and foreign currency exchange rates. We enter into certain derivative transactions to mitigate the volatility associated with these exposures. We have policies in place that define acceptable instrument types we may enter into and we have established controls to limit our market risk exposure. We do not use derivative financial instruments for trading or speculative purposes. In addition, all derivatives, whether designated in hedging relationships or not, are recorded on the Consolidated Balance Sheets at fair value on a gross basis.
Interest Rate Swaps
During the second quarter of fiscal 2019, we entered into a floating-to-fixed interest rate swap agreement to hedge the variability in London Inter-bank Offered Rate (“LIBOR”) based interest payments on a portion of our outstanding variable rate debt. The fair value of our interest rate swaps is estimated using standard valuation models using market-based observable inputs over the contractual term, including one-month LIBOR-based yield curves, among others. We consider the risk of nonperformance, including counterparty credit risk, in the calculation of the fair value. We have designated these swap agreements as cash flow hedges. As cash flow hedges, unrealized gains are recognized as assets and unrealized losses are recognized as liabilities. Unrealized gains and losses are designated as effective or ineffective based on a comparison of the changes in fair value of the interest rate swaps and changes in fair value of the underlying exposures being hedged. The effective portion is recorded as a component of accumulated other comprehensive income or loss, while the ineffective portion is recorded as a component of Interest expense. Changes in the method by which we pay interest from one-month LIBOR to another rate of interest could create ineffectiveness in the swaps, and result in amounts being reclassified from other comprehensive income into Net income. Hedge effectiveness is tested quarterly to determine if hedge treatment is appropriate. Realized gains and losses are recorded on the same financial statement line as the hedged item, which is Interest expense.
52

Foreign Currency Contracts Not Designated as Hedges
On a regular basis, we enter into forward foreign exchange contracts in an effort to mitigate the risks associated with currency fluctuations on certain foreign currency balance sheet exposures. These foreign exchange contracts do not qualify for hedge accounting; therefore, the gains and losses resulting from the impact of currency exchange rate movements on our forward foreign exchange contracts are recognized as Other income (expense), net in the accompanying Consolidated Statements of Income in the period in which the exchange rates change.
SHARE-BASED COMPENSATION
The Company’s long-term equity incentive plan authorizes the Compensation Committee of the Board of Directors to provide equity-based compensation in the form of stock options, restricted stock, restricted stock units (“RSUs”), and performance share units (“PSUs”) for the purpose of providing our employees, officers, and non-employee directors incentives and rewards for performance. We also have an employee stock purchase plan (“ESPP”). All grants under share-based payment plans are accounted for at fair value at the date of grant. We recognize expense on share-based awards to employees expected to vest over the service period, which is the shorter of the period until the employees’ retirement eligibility dates or the service period of the award.
EARNINGS PER SHARE
Basic earnings per share (“EPS”) is calculated by dividing Net income available to common stockholders by the weighted-average number of common shares outstanding during the period, excluding the effects of unvested restricted stock awards with a right to receive non-forfeitable dividends, which are considered participating securities and are included in the calculation using the two-class method.  Diluted EPS is calculated in a similar manner, but the weighted-average number of common shares outstanding during the period is increased to include the weighted-average dilutive effect of "in-the-money" stock options and unvested restricted stock shares using the treasury stock method.
EFFECTS OF RECENT ACCOUNTING PRONOUNCEMENTS
Recently Adopted Accounting Pronouncements
Accounting Standards Update ("ASU") 2016-02 “Leases” (Topic 842) changed the criteria for recognizing leasing transactions. The provisions of this guidance require a lessee to recognize a right of use asset and a corresponding lease liability for operating leases. Under this guidance, rental expense for operating leases, continues to be recognized on a straight-line basis over the non-cancelable lease term. As of October 1, 2019, the Company began applying the provisions of this standard prospectively for all lease transactions as of and after the effective date. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the historical lease classification to carry forward. We did not elect the hindsight practical expedient. Upon adoption, the Company recorded a lease liability of $30,881 and a right of use asset of $30,115. The difference between the right of use asset and lease liability primarily relates to deferred rent recorded prior to adoption. The new guidance did not have a material impact on our results of operations or cash flows for the year ended September 30, 2020. Refer to Note 14 of this Annual Report on Form 10-K for additional information regarding the Company’s lease transactions.
ASU No. 2018-02 “Income Statement – Reporting Comprehensive Income” (Topic 220) allows for an optional one-time reclassification of the stranded tax effects resulting from the change in the U.S. federal corporate income tax rate under the Tax Cuts and Jobs Act (the "Tax Act") from Accumulated other comprehensive income to Retained earnings. The Company adopted this standard effective October 1, 2019, which resulted in an increase of $488 to both Retained earnings and Accumulated other comprehensive loss.
Accounting Pronouncements Issued But Not Yet Adopted
ASU No. 2016-13, "Measurement of Credit Losses on Financial Instruments" (Topic 326) requires financial assets measured at amortized cost to be presented at the net amount expected to be collected using an allowance account and provides that credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. The guidance was amended through various ASU's subsequent to ASU 2016-13, all of which is effective for the Company beginning October 1, 2020. We are finalizing the impact of this standard on our financial statements and it is not expected to have a material impact to the Company’s results of operations or financial condition.
53

ASU No. 2018-13 “Fair Value Measurement” (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement provides specific guidance on various disclosure requirements in Topic 820, including removal, modification and addition to current disclosure requirements. ASU 2018-13 will be effective for us beginning October 1, 2020. We are finalizing the impact of this standard on our disclosures and do not expect the adoption to have a material impact in our disclosures.
ASU No. 2018-15 “Intangibles—Goodwill and Other—Internal-Use Software” (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) requires an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. ASU 2018-15 will be effective for us beginning October 1, 2020. We are finalizing the impact of this standard on our financial statements and do not expect the adoption to have a material impact.
ASU No. 2019-12 “Income Taxes” (Topic 740): Simplifying the Accounting for Income Taxes was issued to simplify Topic 740 through improving consistency and removing certain exceptions to general principles. ASU 2019-12 will be effective for us beginning October 1, 2021. We are currently evaluating the impact of implementing this standard on our financial statements.
ASU No. 2020-04 “Reference Rate Reform” (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting provides optional guidance for accounting for contracts, hedging relationships, and other transactions affected by the reference rate reform, if certain criteria are met. The provisions of this standard are available for election through December 31, 2022. We are currently evaluating the impact of the reference rate reform on our contracts and the resulting impact of adopting this standard on our financial statements.

The intangible assets subject to amortization have a weighted average useful life of 17.9 years. For intangible assets related to the wood treatment business, the remaining useful lives were limited to the end of the calendar year 2021.
The allocation of goodwill to each of the Electronic Materials and Performance Materials segments as a result of the Acquisition was $259,859 and $353,475, respectively.
The following unaudited supplemental pro forma information summarizes the combined results of operations as if the Acquisition had occurred on October 1, 2017.
Year Ended September 30,
2019 2018
Revenue $ 1,099,674  $ 1,063,563 
Net income 67,722  50,055 
Earnings per share - basic $ 2.34  $ 1.74 
Earnings per share - diluted $ 2.30  $ 1.70 
The following costs are included in the years ended September 30, 2019 and 2018:
Non-recurring transaction costs of $2,495 and $33,208, respectively.
Non-recurring transaction-related employee costs, such as accelerated stock compensation costs, retention and severance expense of $427 and $38,132, respectively.
Non-recurring charge for fair value write-up of inventory sold of $0 and $14,869, respectively.

55

The historical financial information has been adjusted by applying the Company’s accounting policies and giving effect to the pro forma adjustments, which consist of (i) amortization expense associated with identified intangible assets; (ii) depreciation of fixed asset step-up (for pre-Acquisition periods only); (iii) accretion of inventory step-up value; (iv) the elimination of Interest expense on pre-Acquisition KMG debt and replacement of Interest expense related to the Acquisition-related financing; (v) transaction-related costs; (vi) accelerated share-based compensation expense (pre-Acquisition periods only); (vii) retention and severance expense incurred as a direct result of the Acquisition; and (viii) an adjustment to tax-effect the aforementioned unaudited pro forma adjustments using an estimated weighted-average effective income tax rate of each entity and the jurisdictions to which the above adjustments relate. The pro forma consolidated results are not necessarily indicative of what the consolidated results actually would have been had the Acquisition been completed on October 1, 2017. The pro forma consolidated results do not purport to project future results of combined operations, nor do they reflect the expected realization of any revenue or cost synergies associated with the Acquisition.

5. FAIR VALUE OF FINANCIAL INSTRUMENTS
The following table presents financial instruments, other than debt, that we measured at fair value on a recurring basis at September 30, 2020 and 2019.  See Note 13 of this Annual Report on Form 10-K for a discussion of our debt. In instances where the inputs used to measure the fair value of an asset fall into more than one level of the hierarchy, we have classified them based on the lowest level input that is significant to the determination of the fair value.

Derivative financial instruments $ —  $ 24,244  $ —  $ 24,244 
Our cash and cash equivalents consist of various bank accounts used to support our operations and investments in institutional money-market funds that are traded in active markets. We invest only in AAA-rated, prime institutional money market funds, comprised of high quality, short-term fixed income securities. Our other long-term investments represent the fair value of investments under our supplemental employee retirement plan (“SERP”), which is a non-qualified supplemental savings plan. The fair value of the investments is determined through quoted market prices within actively traded markets. Although the investments are allocated to individual participants and investment decisions are made solely by those participants, the SERP is a non-qualified plan. Consequently, the Company owns the assets and the related offsetting liability for disbursement until such time as a participant makes a qualifying withdrawal. 
Our derivative financial instruments include foreign exchange contracts and an interest rate swap contract. During the second quarter of fiscal 2019, we entered into a floating-to-fixed interest rate swap contract to hedge the variability in LIBOR-based interest payments on a portion of our outstanding variable rate debt. The fair value of our derivative instruments is estimated using standard valuation models and market-based observable inputs over the contractual term, including one-month LIBOR-based yield curves for the interest rate swap, and forward rates and/or the Overnight Index Swap curve for forward foreign exchange contracts, among others. We consider the risk of nonperformance, including counterparty credit risk, in the calculation of the fair value of derivative financial instruments. See Note 15 of this Annual Report on Form 10-K for more information on our use of derivative financial instruments.

Amortization expense was $85,557, $59,931 and $7,495 for fiscal 2020, 2019 and 2018, respectively.  Estimated future amortization expense of intangible assets as of September 30, 2020 for the five succeeding fiscal years is as follows:

Fiscal Year Estimated
Amortization
Expense
2021 $81,985
2022 74,695
2023 62,879
2024 55,664
2025 50,526
As of September 30, 2020, the estimated fair value of the PIM reporting unit exceeded the carrying value by approximately 8% and no impairment was recognized. In estimating the fair value, the Company used the average of a discounted cash flows model and a market approach based on earnings before interest, taxes, and depreciation for a group of guideline comparable companies. The most significant estimates and assumptions inherent in the discounted cash flows model are the forecasted revenue growth rate, forecasted gross margin, the discount rate and the terminal growth rate. These assumptions are classified as level 3 inputs. The Company’s projections for revenue and gross margin are based on the Company’s multiyear forecast which reflects a recovery from the COVID-19 pandemic (“Pandemic”) during the forecast period. The discount rate was based on an estimated weighted average cost of capital (“WACC”) for the PIM reporting unit. The components of WACC are the cost of equity and the cost of debt, each of which requires judgment by management to estimate. The company developed its cost of equity estimate based on perceived risks and predictability of future cash flows.
The extent to which the Pandemic or future geopolitical events in the oil and gas industry may further impact our PIM business, operations, results of operations and financial condition is uncertain and difficult to estimate, however the impact could negatively affect future revenue and gross margin. The carrying value of the PIM reporting unit includes $318.2 million of goodwill and $46.0 million of trade-name intangible assets. Potential future impairments could be material to the Company’s Consolidated Balance Sheets and to the Consolidated Statements of Income, but we do not expect them to affect the Company’s reported Net cash provided by operating activities. No impairment charges to goodwill were recognized in any periods presented.

10. LONG-LIVED ASSET IMPAIRMENT - WOOD TREATMENT
As a result of to the previously announced planned closure of the Company's wood treatment business' facilities by approximately the end of calendar year 2021, the Company recognized non-cash pre-tax impairment charges in the Performance Materials segment of $2,314 and $67,372, for the years ending September 30, 2020 and 2019, respectively, for the wood treatment asset group which is also a reporting unit, and adjusted the remaining useful lives such that they do not extend beyond the announced plant closures. The Company recognized a tax benefit of $608 and $17,072, for the years ending September 30, 2020 and 2019, respectively in Provision for income taxes in the Consolidated Statements of Income.
The Company tested the recoverability of its long-lived assets and determined the carrying amount of the assets exceeded the sum of the expected undiscounted future cash flows. The resulting impairment charge of $2,314 was recorded to reduce the carrying values of these assets to fair value and was allocated as follows:
September 30,
2020 2019
Property, plant, and equipment, net $ 450  $ 4,063 
Other intangible assets – Product technology 343  9,651 
Other intangible assets – Acquired patents and licenses 102  1,689 
Other intangible assets – Customer relationships, distribution rights, and other 1,419  51,969 
Total $ 2,314  $ 67,372 
Testing the assets for recoverability involves developing estimates of future cash flows directly associated with, and that are expected to arise as a direct result of, the use and eventual disposition of the assets. As the inputs for testing recoverability, including estimates of revenue and expenses, not generally observable in active markets, the Company considers such measurements to be Level 3 measurements in the fair value hierarchy. The duration of the revenue and expense estimates are limited to the period through the closure date.
The fair value of the wood treatment asset group was sufficient such that the recognized impairment was limited to long-lived assets and the reporting unit goodwill was not impaired, however, as the Company approaches the closure date of the facilities and there are lower estimated future cash flows, the carrying value of the wood treatment asset group and reporting unit will not be recoverable, resulting in future impairments. The remaining carrying value of the wood treatment business as of September 30, 2020 includes $35.0 million and $3.8 million of goodwill and intangible assets, respectively, which we anticipate will be periodically impaired through the closure date, resulting in no fair value ascribed to the wood treatment business by the date of closure. The amount of the periodic impairments will vary depending on the timing of the remaining future cash flows of the business.

In connection with the Acquisition, we entered into a credit agreement, which provides for senior secured financing of up to $1,265.0 million (“Credit Agreement”), which includes the Senior Secured Term Loan Facility ("Term Loan Facility") in an aggregate principal amount of $1,065.0 million. During the first quarter of fiscal 2020, the Company amended the Credit Agreement ("Amended Credit Agreement") to reduce the interest rate on the Term Loan Facility. Borrowings under the Term Loan Facility bear interest at a rate per annum equal to, at the Company’s option, either (a) a LIBOR, subject to a 0.00% floor, or (b) a base rate, in each case, plus an applicable margin of, in the case of borrowings under the Term Loan Facility, 2.00% for LIBOR loans and 1.00% for base rate loans. The borrowings are guaranteed by each of the Company’s wholly-owned domestic subsidiaries and are secured by substantially all assets of the Company and of each subsidiary guarantor, in each case subject to certain exceptions.
The Term Loan Facility matures on November 15, 2025, and amortizes in equal quarterly installments of 0.25% of the initial principal amount beginning January 1, 2019. In addition, the Company is required to prepay outstanding loans under the Term Loan Facility, subject to certain exceptions, with up to 50% of the Company’s annual excess cash flow, as defined under the Amended Credit Agreement, and 100% of the net cash proceeds of certain recovery events and non-ordinary course asset sales. We made total prepayments on the Term Loan Facility of $10.0 million and $100.0 million during the fiscal years ended September 30, 2020 and 2019, respectively.
At September 30, 2020, the fair value of the Term Loan Facility, using level 2 inputs, approximated its carrying value of $936,363 as the loan bears a floating market rate of interest.
61

In the second quarter of fiscal 2019, we entered into a floating-to-fixed interest rate swap contract to hedge the variability in our LIBOR-based interest payments on our Term Loan Facility balance. See Note 15 of this Annual Report on Form 10-K for additional information.
The Amended Credit Agreement contains certain affirmative and negative covenants that limit the ability of the Company, among other things and subject to certain significant exceptions, to incur debt or liens, make investments, enter into certain mergers, consolidations, asset sales and acquisitions, pay dividends and make other restricted payments and enter into transactions with affiliates. We believe we are in compliance with these covenants.
The Amended Credit Agreement contains certain events of default, including relating to a change of control. If an event of default occurs, the lenders under the Credit Facilities will be entitled to take various actions, including the acceleration of amounts due under the Credit Facilities.
As of September 30, 2020, scheduled principal repayments of the Term Loan Facility were:
Fiscal Year Principal Repayments
2021 $ 10,650 
2022 10,650 
2023 10,650 
2024 10,650 
2025 10,650 
Thereafter 883,113 
$ 936,363 
Revolving Credit Facility
The Company has a revolving credit facility under the Amended Credit Agreement ("Revolving Credit Facility") with an aggregate principal amount of up to $200.0 million, including a letter of credit sub-facility of up to $50.0 million. Borrowings under the Revolving Credit Facility bear interest at a rate per annum equal to a base rate in each case, plus an applicable margin of 1.50% for LIBOR loans and 0.50% for base rate loans. The applicable margin for borrowings under the Revolving Credit Facility varies depending on the Company’s first lien secured net leverage ratio. The Revolving Facility matures on November 15, 2023, the five-year anniversary of the Acquisition Date.
During the second quarter of fiscal 2020, the Company drew $150.0 million under the Revolving Credit Facility as a precautionary measure in order to increase its cash position and preserve financial flexibility in light of uncertain global economic conditions resulting from the Pandemic. The entire amount, which was unused in full, was repaid in the fourth quarter of fiscal 2020 and no amount remains outstanding as of September 30, 2020.

15. DERIVATIVE FINANCIAL INSTRUMENTS
We are exposed to various market risks, including risks associated with interest rates and foreign currency exchange rates.  We enter into certain derivative transactions to mitigate the volatility associated with these exposures. 
63

Cash Flow Hedges – Interest Rate Swap Contract
We have a floating-to-fixed interest rate swap contract to hedge the variability in LIBOR-based interest payments on a portion of our outstanding variable rate debt.  The notional amount is scheduled to decrease bi-annually and will expire on January 31, 2024. Based on certain quantitative and qualitative assessments, we have determined that the hedge is highly effective and qualifies for hedge accounting. Accordingly, unrealized gains and losses on the hedge are recorded in other comprehensive income. Realized gains and losses are recorded on the same financial statement line as the hedged item, which is Interest expense.
Foreign Currency Contracts Not Designated as Hedges
We enter into forward foreign exchange contracts in an effort to mitigate the risks associated with currency fluctuations on certain foreign currency balance sheet exposures.  These foreign exchange contracts do not qualify for hedge accounting; therefore, the gains and losses resulting from the impact of currency exchange rate movements on our forward foreign exchange contracts are recognized as Other income (expense), net in the accompanying Consolidated Statements of Income in the period in which the exchange rates change. 
The notional amount of our derivative instruments are as follows:
September 30,
2020 2019
Derivatives designated as hedging instruments
Interest rate swap contract $ 571,000  $ 699,000 
Derivatives not designated as hedging instruments
Foreign exchange contracts to purchase U.S. dollars 8,054  6,239 
Foreign exchange contracts to sell U.S. dollars 25,105  24,270 

The fair value of our derivative instruments included in the Consolidated Balance Sheets was as follows:
Derivative Assets Derivative Liabilities
September 30, September 30,
Consolidated Balance Sheets Location 2020 2019 2020 2019
Derivatives designated as hedging instruments

During the first quarter of fiscal 2020, the Company adopted ASU No. 2018-02 regarding the reclassification of stranded tax effects resulting from the change in the U.S. federal corporate income tax rate under the Tax Act and as a result, we reclassified $488 of stranded tax effects from Accumulated other comprehensive income to Retained earnings.

17. SHARE-BASED COMPENSATION PLANS
We grant share-based compensation to eligible participants under our 2012 Omnibus Incentive Plan (the "OIP"), which was amended as of March 2017, and prior to that under our 2000 Equity Incentive Plan (the “EIP”).  The OIP allows for the granting of six types of equity incentive awards: stock options, restricted stock, restricted stock units, stock appreciation rights (“SARs”), performance-based awards, and substitute awards in connection with an acquisition (in the case of the Acquisition, “Replacement Awards”). The OIP authorizes up to 4,978 shares of stock to be granted thereunder, including up to 2,074 shares of stock in the aggregate of awards other than options or SARs and up to 2,539 incentive stock options.  In addition, shares that become available from awards under the EIP and the OIP because of events such as forfeitures, cancellations or expirations will also be available for issuance under the OIP. Shares issued under our share-based compensation plans are issued from new shares rather than from treasury shares.
66

In fiscal 2019, in connection with the Acquisition, we awarded a total of 43,443 restricted stock unit awards to certain KMG employees in substitution for certain unvested restricted stock unit awards that KMG had awarded subsequent to the entry into the definitive agreement for the Acquisition, but prior to the Acquisition Date. The Replacement Awards vest in three equal installments on the first three anniversaries of the original award date. If the recipient was terminated without cause or resigned with good reason during the 18 months following the Acquisition Date, the Replacement Awards will have vested as of such termination date in a number of shares equal to 150% of the Replacement Award.
STOCK OPTIONS
Non-qualified stock options issued under the OIP are generally time-based and provide for a ten-year term, with options generally vesting equally over a four-year period. Non-qualified stock options granted to non-employee directors on an annual basis vest 100% on the first anniversary of the award date. Under the OIP employees may also be granted incentive stock options to purchase common stock at not less than the fair value on the date of the grant, but to date we have not granted incentive stock options.
The fair value of our share-based awards, as shown below, was estimated using the Black-Scholes model with the following weighted-average assumptions:
Year Ended September 30,
2020 2019 2018
Weighted-average grant date fair value $ 39.68  $ 27.34  $ 26.59

As of September 30, 2020, there was $5,267 of total unrecognized share-based compensation expense related to unvested stock options. That cost is expected to be recognized over a weighted-average period of 2.3 years.

EMPLOYEE STOCK PURCHASE PLAN
The ESPP allows all full-time, and certain part-time, employees of our Company and its designated subsidiaries to purchase shares of our common stock through payroll deductions, subject to a maximum number of shares that a participant may purchase and a maximum dollar expenditure in any six-month offering period, and certain other criteria.  The provisions of the ESPP allow shares to be purchased at a price no less than the lower of 85% of the closing price at the beginning or end of each semi-annual stock purchase period. As of September 30, 2020, a total of 291 shares are available for purchase under the ESPP.
The Black-Scholes model is primarily used in estimating the fair value of short-lived exchange traded options that have no vesting restrictions and are fully transferable.  Because employee stock options and ESPP purchases have certain characteristics that are significantly different from traded options, and because changes in the subjective assumptions can materially affect the estimated value, our use of the Black-Scholes model for estimating the fair value of stock options and ESPP purchases may not provide an accurate measure.  Although the value of our stock options and ESPP purchases are determined in accordance with applicable accounting standards using an option-pricing model, those values may not be indicative of the fair values observed in a willing buyer/willing seller market transaction.

Year Ended September 30,

Dividend yield 1.3  % 1.6  % 1.1  %

RESTRICTED STOCK, RESTRICTED STOCK UNITS, AND PERFORMANCE SHARE UNITS
Under the OIP, employees and non-employees may be awarded shares of restricted stock or RSUs, which generally vest over a four-year period. Restricted shares under the OIP may be purchased and placed "on deposit" by executive officers pursuant to the 2001 Deposit Share Program. Shares purchased under this Deposit Share Program receive a 50% match in restricted shares that vest at the end of a three-year period, and are subject to forfeiture upon early withdrawal of the deposit shares. The fair value of our restricted stock and restricted stock unit awards represents the closing price of our common stock on the date of award. Share-based compensation expense related to restricted stock and RSU awards is recorded net of expected forfeitures.
In December 2017, we began awarding PSU awards to certain employees on an annual basis. These PSUs fully vest upon certification of performance achieved with respect to the PSU following the third anniversary of the performance period tied to the PSU, according to the terms and conditions of the relevant PSU award agreement. Stock-based compensation for the awards is recognized over the requisite service period (three years) beginning on the date of award through the end of the performance period based on the number of PSUs expected to vest under the awards at the end of the performance period. The expected amount of vesting is determined using certain performance measures and is re-evaluated at the end of each fiscal year through the end of the performance period. In addition, the PSUs awarded may be subject to downward or upward adjustment depending on the total shareholder return achieved by the Company during the particular performance period related to the PSUs, relative to the total shareholder return of the S&P SmallCap 600 Index or the S&P MidCap 400 Index, as specified in the respective PSU award agreement. We estimate fair value of the PSUs at award date by using a Monte Carlo simulation model. This model simulates the stock price movements of the Company and relevant Index constituents using certain assumptions, including the stock price of our company and relevant Index constituents, the risk-free interest rate and stock price volatility.

Income before income taxes was as follows:
Year Ended September 30,
2020 2019 2018
Domestic $ 94,002  $ (45,364) $ 46,254 
Foreign 79,345  108,470  115,457 
Total $ 173,347  $ 63,106  $ 161,711

Taxes on income consisted of the following:
Year Ended September 30,
2020 2019 2018
U.S. federal and state:
Current $ 20,733  $ 23,461  $ 14,698 
Deferred (7,048) (23,182) 10,347 
Total 13,685  279  25,045 
Foreign:
Current 21,053  27,580  26,135 
Deferred (4,219) (3,968) 488 
Total 16,834  23,612  26,623 
Total U.S. and foreign $ 30,519  $ 23,891  $ 51,668 
The Provision for income taxes at our effective tax rate differed from the statutory rate as follows:
Year Ended September 30,
2020 2019 2018
Federal statutory rate 21.0  % 21.0  % 24.5  %
U.S. benefits from research and experimentation activities (1.5) (2.9) (0.8)
State taxes, net of federal effect 1.1  (4.7) 0.1 
Foreign income at other than U.S. rates 1.7  10.3  1.2 
Excess compensation 0.4  6.4  0.4 
Share-based compensation (2.2) (7.2) (4.3)
U.S. tax reform —  14.1  11.2 
Global Intangible Low Taxed Income ("GILTI") —  3.1  — 
Foreign derived intangible income (3.4) (3.9) — 
Change in reserve positions 1.9  0.3  (0.5)
Other, net (1.4) 1.4  0.2 
Provision for income taxes 17.6  % 37.9  % 32.0  %
The decrease in the effective tax rate during fiscal 2020 was primarily attributable to the absence of a discrete charge recorded in fiscal 2019 related to the final regulations issued under the Tax Act and the absence of unfavorable tax treatment of certain non-deductible costs related to the Acquisition. Additionally, the tax rate was favorably impacted by the final tax regulations issued in July 2020, which provided for a high-tax exception for those jurisdictions subject to the GILTI tax, for which the Company qualified.
The increase in the effective tax rate during fiscal 2019 was primarily due to increased tax expense related to the final regulations related to the Tax Act, which impacted our reserves for uncertain tax positions, and the unfavorable tax treatment of certain Acquisition-related costs. Partially offsetting these adverse items, the Tax Act reduced the corporate income tax rate to 21.0% effective January 1, 2018, resulting in a change in our blended tax rate of 24.5% in fiscal 2018 to 21.0% beginning with our fiscal 2019.
The accounting guidance regarding uncertainty in income taxes prescribes a threshold for the financial statement recognition and measurement of tax positions taken or expected to be taken on a tax return. Under these standards, we may recognize the tax benefit of an uncertain tax position only if it is more likely than not that the tax position will be sustained by the taxing authorities, based on the technical merits of the position.

The following table presents the changes in the balance of gross unrecognized tax benefits during the last three fiscal years:

Balance September 30, 2017 $ 2,270 
Additions for tax positions relating to the current fiscal year 263 
Additions for tax positions relating to prior fiscal years 116 
Lapse of statute of limitations (1,215)
Balance September 30, 2018 1,434 
Additions for tax positions relating to the current fiscal year 271 
Additions for tax positions relating to prior fiscal years 9,839 
Balance September 30, 2019 11,544 
Additions for tax positions relating to the current fiscal year 4,691 
Additions for tax positions relating to prior fiscal years 140 
Reduction for tax positions relating to prior fiscal years (1,337)
Balance September 30, 2020 $ 15,038 
The entire balance of unrecognized tax benefits shown above as of September 30, 2020 and 2019, would affect our effective tax rate if recognized.  Additions for tax positions of $4,691 recorded in the current fiscal year are mainly due to liabilities related to mix of jurisdictional earnings from intercompany transactions. Interest accrued on our Consolidated Balance Sheets was $233 and $281 at September 30, 2020 and 2019, respectively, and any interest and penalties charged to expense in fiscal years 2020, 2019 and 2018 was immaterial.
At September 30, 2020, the tax periods open to examination by the U.S. federal, state and local governments include fiscal years 2013 through 2020, and the tax periods open to examination by foreign jurisdictions include fiscal years 2015 through 2020. We do not anticipate a significant change to the total amount of unrecognized tax benefits within the next 12 months.
Significant components of net deferred tax assets and liabilities were as follows:
September 30,
2020 2019

Prior to enactment of the Tax Act, the Company did not record income tax expense for the undistributed earnings of its international subsidiaries. As a result of the Tax Act, the Company no longer intends to maintain the indefinite reinvestment assertion.

20. COMMITMENTS AND CONTINGENCIES
LEGAL PROCEEDINGS AND OTHER CONTINGENCIES
We periodically become a party to legal proceedings, arbitrations, regulatory proceedings, inquiries and investigations (“contingencies”) arising in the ordinary course of our business operations. The ultimate resolution of these contingencies is subject to significant uncertainty, and should we fail to prevail in any of them or should several of them be resolved against us in the same reporting period, these matters could, individually or in the aggregate, be material to our consolidated financial statements. One of these contingencies, related to Star Lake Canal, which we assumed in connection with the Acquisition, is discussed below. The ultimate outcome of these matters, however, cannot be determined at this time, nor can the amount of any potential loss be reasonably estimated, and as a result except where indicated no amounts have been recorded in our consolidated financial statements.
On May 31, 2019, a fire occurred at the warehouse of the wood treatment facility of KMG’s subsidiary, KMG-Bernuth, Inc.’s (“KMG-Bernuth”), in Tuscaloosa, Alabama, which processes pentachlorophenol (“penta”) for sale to customers in the U.S. and Canada. The warehouse fire, which we believe originated from non-hazardous waste materials temporarily stored in the warehouse for recycling purposes, caused no injuries and was extinguished in less than an hour. Company personnel investigated the incident, and KMG-Bernuth commenced cleanup with oversight from certain local, state and federal authorities. The carrying value of the warehouse and the affected inventory are not material. Applying the accounting guidance under ASC 410-30, Environmental Obligations and ASC 450, Contingencies, we determined that since we had environmental obligations as of the date of the fire, costs for the fire waste cleanup and disposal should be recognized to the extent they are probable and reasonably estimable. We recorded expense of $1,551 and $9,494 for the years ending September 30, 2020 and 2019, respectively. These disposal costs were charged to Cost of sales. Although we believe we have completed cleanup efforts related to the fire incident and the assessment of materials in the warehouse that had been impacted by the incident, there are potential other costs that cannot be reasonably estimated as of this time related to the fire incident due to the nature of federally-regulated penta-related requirements. We incurred significant fire waste cleanup and disposal costs and certain other costs related to the assessment of the impacted warehouse material due to these requirements, and we may incur additional costs related to the fire incident. We intend to continue to update the estimated losses as new information becomes available.
In addition, we are working with our insurance carriers on possible recovery of losses and costs related to the fire incident. We received $468 of insurance recovery during the twelve months ended September 30, 2020 which was recorded in Cost of sales. At this point we cannot reasonably estimate whether we will receive any additional insurance recoveries, or if so, the amount of such recoveries. As such, no additional insurance recoveries have been recognized as of September 30, 2020.
Separately, in 2014, prior to the Acquisition, the United States Environmental Protection Agency (“EPA”) had notified KMG-Bernuth, that the EPA considered it to be a potentially responsible party under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended by virtue of its relationship with certain alleged predecessor companies, including Idacon, Inc (f/k/a Sonford Chemical Company) in connection with the Star Lake Canal Superfund Site near Beaumont, Texas. The EPA has estimated that the remediation will cost approximately $22.0 million. KMG-Bernuth and approximately seven other parties entered into an agreement with the EPA in September 2016 to complete a remedial design phase of the remediation of the site. The remediation work will be performed under a separate future agreement. Although KMG-Bernuth has not conceded liability, a reserve in connection with the remedial design was established, and as of September 30, 2020, the reserve remaining was $553.
We also may face other governmental or third-party claims, or otherwise incur costs, relating to cleanup of, or for injuries resulting from, contamination at sites associated with this or other past and present operations. We accrue for environmental liabilities when a determination can be made that they are probable and reasonably estimable. Other than as described herein, we are not involved in any legal proceedings that we believe could have a material impact on our consolidated financial position, results of operations or cash flows.
73

In addition, our Company is subject to extensive federal, state and local laws, regulations and ordinances in the U.S. and in other countries. These regulatory requirements relate to the use, generation, storage, handling, emission, transportation and discharge of certain hazardous materials, substances and waste into the environment. The Company, including its KMG entities, manage Environmental, Health and Safety (“EHS”) matters related to protection of the environment and human health, the cleanup of contaminated sites, the treatment, storage and disposal of wastes, and the emission of substances into the air or waterways, among other EHS concerns. Governmental authorities can enforce compliance with their regulations, and violators may be subject to fines, injunctions or both. The Company devotes significant financial resources to compliance, including costs for ongoing compliance.
Certain licenses, permits and product registrations are required for the Company’s products and operations in the U.S., Mexico and other countries in which it does business. The licenses, permits and product registrations are subject to revocation, modification and renewal by governmental authorities. In the U.S. in particular, producers and distributors of penta, which is a product manufactured and sold by KMG-Bernuth as part of the wood treatment business, are subject to registration and notification requirements under the Federal Insecticide, Fungicide and Rodenticide Act and comparable state law in order to sell this product in the U.S. Compliance with these requirements may have a significant effect on our business, financial condition and results of operations.
We are subject to contingencies, including litigation relating to EHS laws and regulations, commercial disputes and other matters. Certain of these contingencies are discussed above and below. The ultimate resolution of these contingencies is subject to significant uncertainty, and should we fail to prevail in any of them or should several of them be resolved against us in the same reporting period, these matters could, individually or in the aggregate, be material to the consolidated financial statements. The ultimate outcome of these matters cannot be determined at this time, nor can the amount of any potential loss be reasonably estimated, and as a result except where indicated no amounts have been recorded in our consolidated financial statements.
INDEMNIFICATION
In the normal course of business, we are a party to a variety of agreements pursuant to which we may be obligated to indemnify the other party with respect to certain matters.  Generally, these obligations arise in the context of agreements entered into by us, under which we customarily agree to hold the other party harmless against losses arising from items such as a breach of certain representations and covenants including title to assets sold, certain intellectual property rights and certain environmental matters.  These terms are common in the industries in which we conduct business.  In each of these circumstances, payment by us is subject to certain monetary and other limitations and is conditioned on the other party making an adverse claim pursuant to the procedures specified in the particular agreement, which typically allow us to challenge the other party's claims.
We evaluate estimated losses for such indemnifications under the accounting standards related to contingencies and guarantees.  We consider such factors as the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. To date, we have not experienced material costs as a result of such obligations and, as of September 30, 2020, have not recorded any liabilities related to such indemnifications in our financial statements as we do not believe the likelihood of such obligations is probable.
PURCHASE OBLIGATIONS
Purchase obligations include take-or-pay arrangements with suppliers, and purchase orders and other obligations entered into in the normal course of business regarding the purchase of goods and services. We have been operating under an abrasive particle supply agreement, the current term of which now runs through December 2022. As of September 30, 2020, purchase obligations include $22,932 of contractual commitments related to this agreement. In addition, we have a purchase commitment of $5,631 to purchase non-water based carrier fluid.

22. SEGMENT REPORTING
We identify our segments based on our management structure and the financial information used by our chief executive officer, who is our chief operating decision maker, to assess segment performance and allocate resources among our operating units. Historically, we operated in one industry segment – the development, manufacture and sale of CMP consumables products. In connection with the Acquisition, we reassessed our operating and reportable segments, and determined that we have the following two reportable segments:
Electronic Materials
Electronic Materials includes products and solutions for the semiconductor industry and consists of our CMP slurries business, CMP pads business, and electronic chemicals business.
Performance Materials
Performance Materials consists of our PIM business, wood treatment business, and QED business.
75

Beginning in fiscal 2019 and with the Acquisition, our chief operating decision maker evaluates segment performance based upon revenue and segment adjusted EBITDA. Segment adjusted EBITDA is defined as earnings before interest, income taxes, depreciation and amortization, adjusted for certain items that affect comparability from period to period.  These adjustments include items related to the Acquisition, such as Acquisition and integration-related expenses, the impact of fair value adjustments to inventory acquired from KMG, certain costs related to the KMG-Bernuth warehouse fire, net of insurance recovery, asset impairment charges and net restructuring charges related to the wood treatment business and costs related to the Pandemic, net of grants received. We exclude these items from earnings when presenting our adjusted EBITDA measure because we believe they are not indicative of a segment's regular, ongoing operating performance. Adjusted EBITDA is also the basis of a performance metric for our fiscal 2020 Short-Term Incentive Program. In addition, our chief operating decision maker does not use assets by segment to evaluate performance or allocate resources, and therefore, we do not disclose assets by segment.
Since the two segments operate independently and serve different markets and customers, as a result there are no sales between segments.  Revenue from external customers and segment adjusted EBITDA shown for Performance Materials for the year ended September 30, 2018 include the precision optics business. Revenue from external customers by segment are as follows:

INDEX
MANAGEMENT RESPONSIBILITY
The accompanying consolidated financial statements were prepared by the Company in conformity with accounting principles generally accepted in the United States of America. The Company's management is responsible for the integrity of these statements and of the underlying data, estimates and judgments.
The Company's management establishes and maintains a system of internal accounting controls designed to provide reasonable assurance that its assets are safeguarded from loss or unauthorized use, transactions are properly authorized and recorded, and that financial records can be relied upon for the preparation of the consolidated financial statements. This system includes written policies and procedures, a code of business conduct and an organizational structure that provides for appropriate division of responsibility and the training of personnel. This system is monitored and evaluated on an ongoing basis by management in conjunction with its internal audit function.
The Company's management assesses the effectiveness of its internal control over financial reporting on an annual basis. In making this assessment, management uses the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework (2013). Management acknowledges, however, that all internal control systems, no matter how well designed, have inherent limitations and can provide only reasonable assurance with respect to financial statement preparation and presentation. In addition, the Company's independent registered public accounting firm evaluates the Company's internal control over financial reporting and performs such tests and other procedures as it deems necessary to reach and express an opinion on the fairness of the financial statements.
In addition, the Audit Committee of the Board of Directors provides general oversight responsibility for the financial statements. Composed entirely of Directors who are independent and not employees of the Company, the Committee meets periodically with the Company's management, internal auditors and the independent registered public accounting firm to review the quality of financial reporting and internal controls, as well as results of auditing efforts. The internal auditors and independent registered public accounting firm have full and direct access to the Audit Committee, with and without management present.

ITEM 9A. CONTROLS AND PROCEDURES
EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES
Our management, with the participation of our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), has conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act")), as of September 30, 2020.  Based on that evaluation, our CEO and CFO have concluded that our disclosure controls and procedures were effective to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and to ensure that such information is accumulated and communicated to management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.
While we believe the present design of our disclosure controls and procedures is effective enough to make known to our senior management in a timely fashion all material information concerning our business, we intend to continue to improve the design and effectiveness of our disclosure controls and procedures to the extent necessary in the future to provide our senior management with timely access to such material information, and to correct any deficiencies that we may discover in the future, as appropriate.
MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. Internal control over financial reporting is defined in Rule 13a-15(f) or Rule 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the Company's CEO and CFO, or person’s performing similar functions, and effected by the Company’s board of directors, management and other personnel to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America. Internal control over financial reporting includes policies and procedures that: pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions and dispositions of the Company's assets; provide reasonable assurance that transactions are recorded as necessary for preparation of our financial statements in accordance with generally accepted accounting principles; provide reasonable assurance that receipts and expenditures of Company assets are made in accordance with management authorization; and provide reasonable assurance that unauthorized acquisition, use or disposition of Company assets that could have a material effect on our financial statements would be prevented or detected on a timely basis. 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.
Our management evaluated the effectiveness of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this evaluation, our management concluded that the Company's internal control over financial reporting was effective as of September 30, 2020.  The effectiveness of the Company's internal control over financial reporting as of September 30, 2020 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears under Item 8 of this Annual Report on Form 10-K.
CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING
There were no changes in our internal control over financial reporting that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

INDEX
INHERENT LIMITATIONS ON EFFECTIVENESS OF CONTROLS
Because of inherent limitations, our disclosure controls or our internal control over financial reporting may not prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Exhibit 4.2

DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934
The following summary of the capital stock of CMC Materials, Inc. does not purport to be complete and is qualified in its entirety by reference to our (second) amended and restated certificate of incorporation (as amended, our “charter”), our (fourth) amended and restated by-laws (our “by-laws”, and together with our charter, as amended and restated, our “organizational documents”), each of which are incorporated by reference as an exhibit to the Annual Report on Form 10-K of which this Exhibit is a part, and certain provisions of Delaware law. Unless the context requires otherwise, all references to “we”, “us,” “our” and “CMC Materials” in this section refer solely to CMC Materials, Inc. and not to our subsidiaries.
General
Under our charter, CMC Materials, Inc.’s authorized capital stock consists of 20,000,000 shares of common stock, $0.001 par value per share, and 200,000,000 shares of preferred stock, $0.001 par value per share. As of October 31, 2020, there were 29,081,617 shares of CMC Materials common stock outstanding and no shares of CMC Materials preferred stock outstanding. All outstanding shares of CMC Materials common stock are duly authorized, validly issued, fully paid and non-assessable.
Common Stock
Voting
Holders of CMC Materials common stock are entitled to one vote per share on all matters to be voted on by CMC Materials stockholders. Holders of CMC Materials common stock do not have cumulative rights, so that holders of a majority of the shares of CMC Materials common stock present at a meeting at which a quorum is present are able to elect all of CMC Materials directors eligible for election in a given year. The holders of a majority of the voting power of the issued and outstanding CMC Materials common stock constitute a quorum.
Dividends
Holders of CMC Materials common stock are entitled to receive ratably the dividends, if any, that are declared by the CMC Materials board of directors. The CMC Materials board of directors may declare dividends out of funds legally available for the declaration of dividends, subject to the preferential rights of any holder of preferred stock that may from time to time be outstanding.
Liquidation Rights
Upon the liquidation, dissolution or winding up of CMC Materials, the holders of CMC Materials common stock are entitled to share pro rata in the distribution of all of the assets available for distribution after satisfaction of all liabilities and the payment of the liquidation preference of any preferred stock that may be outstanding.
Other Matters
The holders of CMC Materials common stock will have no preemptive or other subscription rights to purchase common stock, and there are no redemptive rights or sinking fund provisions.
The rights, preferences and privileges of holders of CMC Materials common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of preferred stock that CMC Materials Microelectronics may designate and issue in the future.
CMC Materials common stock is listed on The Nasdaq Global Select Market under the symbol “CCMP.”
The transfer agent and registrar for CMC Materials common stock is Computershare Trust Company, N.A.





Preferred Stock 
The CMC Materials board of directors is authorized to cause shares of preferred stock to be issued in one or more series, to:
determine the number of shares of each series;
fix the rights, powers, preferences and privileges of each series;
fix any qualifications, limitations or restrictions thereon; and
increase or decrease the number of shares of each such series.
Among the specific matters that may be determined by the board of directors are:
the annual rate of dividends;
the redemption price, if any;
the terms of a sinking or purchase fund, if any;
the amount payable in the event of any voluntary liquidation, dissolution or winding up of the affairs of CMC Materials;
conversion rights, if any; and
voting powers, if any.
Depending upon the terms of the preferred stock established by the CMC Materials board of directors, any or all series of preferred stock could have preferences over the common stock with respect to dividends and other distributions and upon liquidation or could have voting or conversion rights that could adversely affect the holders of the outstanding common stock.
Certain Effects of Authorized but Unissued Stock
CMC Materials has shares of common stock and preferred stock available for future issuance without stockholder approval. CMC Materials may utilize these additional shares for a variety of corporate purposes, including future public offerings to raise additional capital or facilitate corporate acquisitions or for payment as a dividend on the capital stock. The existence of unissued and unreserved common stock and preferred stock may enable the CMC Materials board of directors to issue shares to persons friendly to current management or to issue preferred stock with terms that could render more difficult or discourage a third-party attempt to obtain control of CMC Materials by means of a merger, tender offer, proxy contest or otherwise, thereby protecting the continuity of CMC Materials' management.
Provisions of CMC Materials Charter, CMC Materials Bylaws and DGCL That May Have Anti-Takeover Effects
The CMC Materials charter, the CMC Materials bylaws and Section 203 of the Delaware General Corporation Law (“DGCL”) contain provisions summarized below that may delay, discourage or prevent the acquisition or control of CMC Materials by means of a tender offer, open market purchase, proxy fight or otherwise, including acquisitions that might result in a premium being paid over the market price of the common stock.
Stockholder Action by Written Consent; Special Meetings
Any action required or permitted to be taken by CMC Materials stockholders may be effected only at a duly called annual or special meeting of stockholders and may not be effected by a written consent in lieu of a meeting of stockholders. Except as otherwise required by law and subject to the rights of the holders of any preferred stock, special meetings of stockholders for any purpose may be called only by the CMC Materials board of directors, its chairman or, at the written request of a majority of the CMC Materials board of directors, the president.




Advance Notice Procedures
The CMC Materials bylaws require advance notice of the nomination, other than by or at the direction of the CMC Materials board of directors, of candidates for election as directors, as well as for other stockholder proposals, to be considered at special meetings of stockholders. Subject to certain exceptions, notice of intent to nominate a director or raise matters at these meetings will have to be received in writing not less than 90 nor more than 120 days prior to the anniversary of the previous year's annual meeting of stockholders, and must contain specific information concerning the person to be nominated or the matters to be brought before the meeting and concerning the stockholder submitting the proposal. If the chairman of a meeting determines that an individual was not nominated, or other business was not brought before the meeting, in accordance with the advance notice procedures, that individual will not be eligible for election as a director, or that business will not be conducted at such meeting, as the case may be.
Board of Directors
The CMC Materials charter and bylaws provide that the number of directors shall be determined from time to time by a resolution adopted by the majority of the CMC Materials directors. The CMC Materials charter and bylaws also provide that the board of directors be divided into three classes, as nearly equal in number as possible. Each director holds office until that person's successor is duly elected and qualified. Vacancies on the board of directors are filled by a majority of the remaining directors, or by a sole remaining director, or by CMC Materials stockholders if the vacancy was caused by the action of CMC Materials stockholders.
Any director may be removed from office with or without cause upon the affirmative vote of holders of at least 80% of the CMC Materials outstanding common stock, voting as a single class. A director may not be removed by the stockholders at a meeting unless the notice of the meeting states that the purpose, or one of the purposes, of the meeting is removal of the director.
Adoption, Amendment or Repeal of Charter or Bylaws
The CMC Materials charter provides that the affirmative vote of holders of at least 80% of CMC Materials outstanding common stock is required to amend, repeal or adopt any provision of the CMC Materials charter inconsistent with the provisions of that certificate regarding amendments to the CMC Materials bylaws, stockholder action by written consent, special meetings of stockholders, the CMC Materials board of directors and the election and removal of directors. The CMC Materials charter further provides that the CMC Materials bylaws may be altered, amended or repealed only by the CMC Materials board of directors or upon the affirmative vote of holders of at least 80% of the CMC Materials outstanding common stock, voting together as a single class.
Takeover Statutes
Section 203 of the DGCL generally prohibits “business combinations,” including mergers, sales and leases of assets, issuances of securities and similar transactions by a corporation or a subsidiary with an interested stockholder who beneficially owns 15% or more of a corporation's voting stock, within three years after the person or entity becomes an interested stockholder, unless: (i) the board of directors of the target corporation has approved, before the acquisition time, either the business combination or the transaction that resulted in the person becoming an interested stockholder, (ii) upon consummation of the transaction that resulted in the person becoming an interested stockholder, the person owns at least 85% of the corporation's voting stock (excluding shares owned by directors who are officers and shares owned by employee stock plans in which participants do not have the right to determine confidentially whether shares will be tendered in a tender or exchange offer) or (iii) after the person or entity becomes an interested stockholder, the business combination is approved by the board of directors and authorized at a meeting of stockholders by the affirmative vote of at least 662/3% of the outstanding voting stock not owned by the interested stockholder. CMC Materials has not opted out of the protections of Section 203 of the DGCL.

GRANTING OF OPTION

On an Enrollment Date each participant shall be deemed to have been granted an option to purchase a number of shares of Common Stock determined by dividing the participant’s accumulated payroll deductions on the Exercise Date by the lower of (i) 85% of the Fair Market Value of a share of Common Stock on the Enrollment Date or (ii) 85% of the Fair Market Value of a share of Common Stock on the Exercise Date; subject, however, to any applicable limitations contained in this Plan. In addition, the maximum number of shares a participant may purchase with respect to any Offering Period is that number of shares determined by dividing $12,500 by the Fair Market Value of a share of Common Stock on the Enrollment Date; provided, however, the maximum number of shares a participant may purchase with respect to the first Offering Period is that number of shares determined by dividing $25,000 by the Fair Market Value of a share of Common Stock on the Enrollment Date.
ARTICLE VII
EXERCISE OF OPTION
7.01Automatic Exercise. Subject to the next following sentence, each Plan participant’s option for the purchase of stock with payroll deductions made during any Offering Period will be exercised automatically on the applicable Exercise Date for the purchase of the number of full and fractional shares of Common Stock that the accumulated payroll deductions in the participant’s account at the time will purchase at the Purchase Price (but not in excess of the maximum number of shares determined pursuant to Section 6.01). The Committee shall have the discretion to reduce the number of shares of Common Stock to be purchased by participants with respect to an Offering Period and to allocate such reduced number of shares of Common Stock among participants in such Offering Period, so long as such reduction and allocation is done in a manner consistent with Section 423 of the Code. Any payroll deductions not applied to the purchase of shares of Common Stock by reason of the limitations of or reduction pursuant to this Section 7.01 shall be promptly refunded to participants after the Exercise Date of the Offering Period to which such reduction applies.
7.02Withdrawal of Account. No participant in the Plan shall be entitled to withdraw any amount from the accumulated payroll deductions in his or her account; provided, however, that a participant’s accumulated payroll deductions shall be refunded to the participant as and to the extent specified in Section 8.01 below upon termination of such participant’s participation in the Plan.

The Fair Market Value of all deemed fractional shares shall be paid in cash, if applicable.
7.04Exercise of Options. During a participant’s lifetime, options held by such participant shall be exercisable only by such participant.
7.05Delivery of Stock. As promptly as practicable after each Exercise Date, the Company will deliver to each participant the shares of Common Stock purchased upon exercise of such participant’s option. The Company may deliver such shares in certificated or book entry form, at the Company’s sole election.

MISCELLANEOUS
13.01Transferability. Neither payroll deductions credited to any participant’s account nor any option or other rights with regard to the exercise of an option to receive Common Stock under the Plan may be assigned, transferred, pledged, or otherwise disposed of in any way by the participant other than by will or the laws of descent and distribution. Any such attempted assignment, transfer, pledge or other disposition shall be without effect except that the Company may, in its discretion, treat such act as an election to withdraw from participation in the Plan in accordance with Section 8.01.

None of the foregoing actions shall be considered to have adversely affected any right of any participant.
13.06In the event that the Committee determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Committee may, in its discretion and, to the extent necessary or desirable, modify or amend the Plan to reduce or eliminate such accounting consequence including, but not limited to:

As a condition to the exercise of an option, the Company may require the person exercising such option to represent and warrant at the time of any such exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned applicable provisions of law.
13.09Effective Date. The Plan shall become effective as of its adoption by the Board, subject to approval by the holders of a majority of the shares of Common Stock, and shall continue in effect until the shares of Common Stock reserved for issuance under the Plan

13.11Effect of Plan. The provisions of the Plan shall, in accordance with its terms, be binding upon, and inure to the benefit of, all successors of each Employee participating in the Plan, including, without limitation, such Employee’s estate and the executors, administrators or trustees thereof, heirs and legatees, and any receiver, trustee in bankruptcy or representative of creditors of such Employee.

CMC MATERIALS, INC.
DIRECTORS' DEFERRED COMPENSATION PLAN

AS AMENDED AND RESTATED SEPTEMBER 23, 2008

CMC Materials, Inc. (the "Company") desires to amend and restate the Directors' Deferred Compensation Plan (the "Plan"). The Plan as originally adopted March 13, 2001 and as amended as of June 17, 2003 (attached hereto as Exhibit A) remains in effect for amounts deferred prior to January 1, 2005. The Plan was previously amended and restated as of September 26, 2006, and is further amended and restated effective September 23, 2008 as set forth herein.
The Plan is designed to assist the Company in attracting and retaining persons of competence and stature to serve as Directors by giving those Directors the option of deferring receipt of the fees payable to them by the Company for their services as Directors and creating an opportunity for appreciation of fees deferred based on appreciation of the Company's Common Shares.
Therefore, the Company hereby adopts the Plan as hereinafter set forth:
1.Effective Date. The Plan is amended and restated effective as of the date executed as set forth below.
2.Eligibility and Participation. Each Director of the Company who: (a) is duly elected to the Company's Board of Directors (the "Board of Directors" or the "Board"); (b) receives fees, stipends, awards, or other remuneration ("Directors' Fees") from the Company for services as a Director; and (c) is not an employee of the Company, is an "Eligible Director." Each Eligible Director may defer receipt of Directors' Fees otherwise payable to that Eligible Director, as provided for in the Plan, beginning on the date he or she is first elected to the Company's Board. Each Eligible Director who elects to defer Directors' Fees under the Plan is a "Participant" in the Plan.
3.Administration. The Board appoints the Company's Chief Executive Officer and the Company's General Counsel to act as the administrators of the Plan (separately and collectively referred to herein as the "Administrator"). The Administrator will serve at the pleasure of the Board of Directors and will administer, construe and interpret the Plan. The Administrator will not be liable for any act done or determination made in good faith. The Board of Directors has the power to designate an additional or replacement Administrator at its discretion. The expense of administering the Plan shall be borne by the Company and shall not be charged against benefits payable hereunder.
4.Deferrals.
(a)Deferral Election. An Eligible Director may file with the Administrator, on or before December 31 of each year, an election in writing to defer all or a portion of the Directors' Fees to be earned by the Eligible Director in the following calendar year (a



"Deferral Election"). The Deferral Election shall remain in effect until changed or revoked, but as of each December 31 it shall be irrevocable with respect to Directors Fees to be earned by the Director in the immediately following year. In the year in which a Director first becomes eligible to participate in the Plan, a Deferral Election may be made with respect to services to be performed subsequent to the date of the Deferral Election, if it is filed with the Administrator within thirty (30) days after the date the Director becomes eligible to participate in the Plan. When a Deferral Election is filed, an amount equal to all or a portion (as designated in the Deferral Election) of the Directors' Fees earned by the Participant for the following calendar year (or the remainder of the calendar year, in the case of new Directors) will be credited to a deferral account maintained on behalf of that Participant (the "Deferral Account"). Each Deferral Election must also specify a distribution commencement date and a method of distribution (lump sum or equal installments), consistent with the terms of paragraph 5.
(b)Minimum Deferral. The amount of Deferral Election may not be less than $1,000 per calendar quarter.
(c)Accounting. The Deferral Accounts will be maintained by the Company and will list and reflect each Participant's credits and valuations. The Administrator will provide each Participant an annual statement of the balance in that Participant's Deferral Account. The Company will credit to each Participant's Deferral Account an amount equivalent to the Directors' Fees or portion thereof, as designated in the Deferral Election, that would have been paid to the Participant if the Participant had not elected to defer such compensation under the Plan. The credit will be made on the date on which the Directors' Fees would have been paid absent a Deferral Election. The Plan is unfunded and no funds will be segregated into the Deferral Account of Participants.
(d)Valuation. Each Deferral Account will be credited a number of Share Units (including fractions thereof) determined by dividing the amount to be credited to the Deferral Account, whether in lieu of payment of Directors' Fees or as a dividend or other distribution attributable to those Share Units, by the Fair Market Value of the Company's Common Shares (as defined below) on the date of credit. Fair Market Value of the Company's Common Shares means: (i) the closing price of the Company's Common Shares on the principal exchange on which the Company's Common Shares are then trading, if any, on the date such Share Units are to be credited, or, if Shares were not traded on the date of crediting, then on the next preceding trading day during which a sale occurred; or (ii) if the Common Shares are not traded on an exchange but are quoted on the Nasdaq National Market System or a successor quotation system, (1) the last sales price (if the Common Shares are then listed as a National Market Issue under Nasdaq), or (2) the mean between the closing representative bid and asked prices for the Common Shares on the date of credit as reported by Nasdaq or a successor quotation system, or (iii) if the Common Shares are not publicly traded on an exchange and not quoted on Nasdaq or a successor quotation system, the mean between the closing bid and asked prices for the Common Shares on the date of credit, as determined in good faith by the Company's Chief Financial Officer; or (iv) if the Company's Common Shares are not publicly traded, the fair market value established by the Company's Chief Financial

2


Officer acting in good faith. Each Share Unit will have the value of a Common Share of the Company. The number of Share Units will be adjusted proportionally to reflect stock splits, stock dividends or other capital adjustments effected without receipt of consideration by the Company, provided, that, in the event of a merger, acquisition or other business combination of the Company with or into another entity, any adjustment provided for in the applicable agreement and plan of merger (or similar document) shall be conclusively deemed to be appropriate for purposes of this Section.
5.Distribution. A Participant must elect in writing, at the time each Deferral Election is made under paragraph 4(a), the date on which distribution of the amounts credited to the Participant's Deferral Account to which that Deferral Election relates will commence and the method of distribution, as permitted hereunder. A Participant's distribution election must specify that distribution will occur on the event or date set forth in paragraph (a)(i) or (ii) below. The distribution date elected by the Participant for Directors' Fees deferred in a given year shall be the Scheduled Withdrawal Date and may vary with each year, pursuant to the terms of the Deferral Election. A Participant's Scheduled Withdrawal Date with respect to Directors' Fees deferred in a given year can be no earlier than two years from the last day of the year in which the deferrals are made, other than for "Separation from Service" (as described in paragraph 5(a) below), and will be no later than the date the Participant experiences a Separation from Service as a Director. Payment will be made in the Company's Common Shares only, in one distribution or equal installment distributions based on the number of Share Units attributable to the applicable Deferral Election. Installments may not be made more often than monthly and may not extend for more than five years. The time of and method of distribution of benefits may vary with each separate Deferral Election. The Deferral Accounts represent an unsecured right to acquire the Company's Common Shares. In the event a Participant does not elect a Scheduled Withdrawal Date, all deferred amounts will be distributed within thirty (30) days following the Participant's Separation from Service (as described in paragraph 5(a) below).
(a)Time of Distribution. A Participant's Accounts under the Plan may be paid only upon an event or at a time set forth in this paragraph 5(a):
(i)The Participant's "Separation from Service" (as defined in Treas. Reg. §1.409A-1(h) and in accordance with Treas. Reg. §1.409A-1(i)(2)).
(ii)On a specified date prior to the Participant's Separation from Service, but no earlier than two years from the last day of the year in which the Directors' Fees are deferred, or according to a fixed schedule of equal installments not more frequent than monthly and over a period of not longer than five years (in accordance with Treas. Reg. §1.409A-1(i)(1)).
(iii)The Participant's "Disability" (in accordance with Treas. Reg. §1.409A-3(i)(4)).
(iv)The Participant's death.

3


(v)A change in the ownership or effective control of the corporation, or in the ownership of a substantial portion of the assets of the corporation (in accordance with Treas. Reg. §1.409A-3(i)(5)).
(vi)The occurrence of an "Unforeseeable Emergency," in accordance with Treas. Reg. §1.409A-3 (i)(3), and paragraph 6 of the Plan.
(b)Method of Distribution. Deferred amounts will be paid in the Company's Common Shares. Payments will be made in a lump sum or in equal installments not more frequent than monthly and over a period of not longer than five years. A Participant must elect in writing, at the time each Deferral Election is made, the method of distribution of the Participant's Deferral Account, as permitted hereunder, to which that Deferral Election relates. The method of distribution of benefits may vary with each year, pursuant to the terms of the Deferral Election. In the event a Participant does not elect a method of distribution with respect to a particular year’s deferrals, the deferred amounts for such year will be distributed in a single lump sum. The Participant shall receive Common Shares equal to the number of Share Units in the Deferral Accounts as of the occurrence of the event upon which the Participant's Accounts are payable. Fractional Share Units may be settled in cash or otherwise as the Company determines.
(c)Changes to Time or Method of Distribution. Except as provided in this paragraph 5(c) or in paragraph 5(d), no Participant may change a Scheduled Withdrawal Date or a method of distribution designated in a Deferral Election, and in no case shall such change be made if it would result in the deferral of any amount in the Participant's Deferral Account later than that Participant's Separation from Service. Any change in a Scheduled Withdrawal Date that is not the Participant's Separation from Service must be made by the Participant by submitting a new Deferral Election at least twelve (12) months prior to the Scheduled Withdrawal Date. Any deferred amounts for which the Scheduled Withdrawal Date or the method of distribution is changed shall be deferred for an additional period of not less than five (5) years from the date the Participant otherwise would have received the distribution, except with regard to payments made due to the Participant's death or Disability or an Unforeseeable Emergency. A new Scheduled Withdrawal Date may not take effect until at least twelve (12) months after the date on which it is elected.
6.Unforeseeable Emergency. Distribution of a Participant's Deferral Account may be made to a Participant prior to his or her Separation from Service in the event an "Unforeseeable Emergency," as that term is defined for purposes of Code Section 409A and the regulations issued thereunder. An Unforeseeable Emergency is generally a severe financial hardship resulting from an illness or accident of the Participant, the Participant's spouse or a dependent of the Participant, loss of the Participant's property due to casualty, or other similar extraordinary and unforeseeable circumstances arising as a result of events beyond the control of the Participant. Consistent with the Code, any distributions from a Participant's Deferral Account made in the event of an Unforeseeable Emergency may not exceed the amount required to satisfy such emergency plus amounts necessary to pay taxes reasonably anticipated as a result of the distribution, after taking into account the extent to which such hardship is or may be

4


relieved through reimbursement or compensation by insurance or otherwise by liquidation of the Participant's assets (to the extent liquidation of such assets would not itself cause severe financial hardship).
7.Separation from Service due to Death or Disability.
(a)In the event of a Participant's Separation from Service by reason of death or Disability prior to the distribution of any portion of that Participant's Deferral Account, the Administrator will, within ninety (90) days of the date of Separation from Service, commence distribution of amounts credited to the Deferral Account to the beneficiary or beneficiaries of the Participant or to the Participant.

The Participant's relationship to the

6


Company under the Plan shall be only that of a general unsecured creditor and neither this Plan, nor any agreement entered into hereunder, or action taken pursuant hereto shall create or be construed to create a trust for purposes of holding and investing the Deferred Account balances.

Reg. §1.409A-3(j)(4)(ix) or any successor provisions thereto. Any amendment or termination of this Plan will not adversely affect the rights of a Participant accrued prior thereto without that Participant's written consent, except to the extent required by law.

2012 OMNIBUS INCENTIVE PLAN
(as amended effective March 7, 2017)

1.    PURPOSE
    The purpose of this CMC Materials, Inc. 2012 Omnibus Incentive Plan, as amended (the “Plan”), is to advance the interests of CMC Materials, Inc. (the “Company”) and its stockholders by enhancing the Company’s ability to (a) attract and retain employees, directors, consultants and advisors who are in a position to make significant contributions to the success of the Company and its subsidiaries; (b) reward these individuals for these contributions; (c) encourage these individuals to take into account the short-term and long-term interests of the Company and its stockholders; and (d) reward individuals who have contributed, or are expected to contribute, to the Company’s success, by providing them equity and cash incentives (“Awards”).
2.    ADMINISTRATION
    (a)    The Plan shall be administered by the Compensation Committee of the Board of Directors (the “Board”) of the Company (the “Committee”). The Committee shall hold meetings at such times as the Committee shall deem necessary for the proper administration of the Plan. The Committee shall consist of at least two directors of the Company, each of whom shall be a “Non-Employee Director” as defined in Rule 16b-3(b)(3) promulgated under Section 16 of the Securities Exchange Act of 1934, as amended (the “1934 Act”), and (ii) to the extent necessary for any Award intended to qualify as “qualified performance-based compensation” under Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), to so qualify, each member of the Committee shall be an “outside director” (as defined in Section 162(m) and the regulations promulgated thereunder). Subject to applicable law, the Committee may delegate its authority under the Plan to any other person or persons other than with respect to grants to individuals subject to Section 16 of the 1934 Act.
    (b)    No member of the Committee shall be liable for any action, failure to act, determination or interpretation made in good faith with respect to this Plan or any transaction hereunder. The Company hereby agrees to indemnify each member of the Committee for all costs and expenses and, to the fullest extent permitted by applicable law, any liability incurred in connection with defending against, responding to, negotiating for the settlement of or otherwise dealing with any claim, cause of action or dispute of any kind arising in connection with any actions in administering this Plan or in authorizing or denying authorization to any transaction hereunder.
    (c)    Subject to the express terms and conditions set forth herein, the Committee shall have the power from time to time:
    (i)    to determine the employees of the Company, its subsidiaries and affiliates (“Employees”), non-employee members of the board of directors of the Company, its subsidiaries or affiliates (“Directors”), and consultants and advisors of the Company or any of its subsidiaries (“Advisors”), to whom Awards shall be granted under the Plan (any such individual, a “Participant”) and the number of shares of Stock subject to share-based Awards; to prescribe the terms and conditions (which need not be identical) of each such Award, including with respect to determining exercise prices, vesting conditions, restrictions on transfer, and, to the extent consistent with the terms of the Plan, whether to waive or modify such conditions (including to



accelerate or waive vesting conditions); and to make any amendment or modification to any Award Agreement (as defined herein) consistent with the terms of the Plan;
    (ii)    to construe and interpret the Plan and the Awards granted hereunder; to establish, amend and revoke rules and regulations for the administration of the Plan, including, but not limited to, correcting any defect or supplying any omission, or reconciling any inconsistency in the Plan or in any Award Agreement, in the manner and to the extent it shall deem necessary or advisable; and otherwise to give full effect to the Plan;
    (iii)    to exercise its discretion with respect to the powers and rights granted to it as set forth in the Plan;
(iv)    to establish any “blackout” period that the Committee in its sole discretion deems necessary or advisable; and
    (v)    generally, to exercise such powers and to perform such acts as are deemed by it necessary or advisable to promote the best interests of the Company with respect to the Plan.
    All decisions and determinations of the Committee in the exercise of the foregoing powers shall be final, binding and conclusive upon the Company and its subsidiaries and affiliates, all Participants, and all other persons claiming any interest herein.
3.    EFFECTIVE DATE AND TERM OF PLAN
    The Plan, as amended through March 7, 2017, was originally effective as of January 16, 2012, the date of its adoption by the Board (the “Effective Date”), subject to approval by the Company’s stockholders. No Award may be granted under the Plan after the tenth anniversary of the Effective Date, but Awards previously granted may extend beyond that date.
4.    SHARES SUBJECT TO THE PLAN
(a)    Awards under the Plan shall consist of Restricted Stock, RSUs, Options, SARs, Performance Shares, Performance Units, and Cash Incentive Awards (each as defined and described in Section 6 below).
(b)    Subject to adjustment as provided in Section 8.6: (i) the maximum number of shares of the Company’s common stock, par value $.001 per share (“Stock”), subject to Awards that may initially be delivered under the Plan is 2,901,360, plus any shares of Stock that are or become available under the Second Amended and Restated Cabot Microelectronics Corporation 2000 Equity Incentive Plan, As Amended and Restated September 23, 2008 (the “Prior Plan”), on or after the date the Plan is approved by the Company’s stockholders; (ii) the maximum number of shares of Stock and share equivalent units that may be granted during any calendar year to any one Participant under Awards other than Options, SARs, or Cash Incentive Awards, in the aggregate, is 435,204, to the extent such Awards are intended to qualify as “qualified performance-based compensation” under Section 162(m) of the Code, which limit shall apply regardless of whether the Award(s) are paid in Stock or cash; (iii) the maximum number of shares of Stock and share equivalent units that may be granted during any calendar year to any one Participant under Options and SARs, in the aggregate, is 435,204; and (iv) in no event shall the Company issue more than 2,030,952 shares of Stock in the aggregate under Awards other than Options, SARs, and Cash Incentive Awards under the Plan. No awards shall be granted under the Prior Plan following the date the Plan is initially approved by the Company’s stockholders. For the avoidance of doubt, each limit on

- 2 -


shares of Stock and share equivalent units described in this Section 4(b) reflects the adjustment previously made in accordance with the Plan’s terms following the Company’s leveraged recapitalization with a special cash dividend completed on March 2, 2012.
    (c)    Any Stock covered by an Award which is forfeited, canceled or expires in whole or in part shall be deemed not to be delivered for purposes of determining the maximum number of shares of Stock available for grants under the Plan. For purposes of determining the number of shares of Stock available for grant under the Plan, (i) if the exercise price of an Option or Stock-settled SAR (including any Option or Stock-settled SAR granted under the Prior Plan) is satisfied by delivering shares of Stock to the Company (by either actual delivery or by attestation), the total number of shares subject to such Option or Stock-settled SAR shall be deemed delivered for purposes of determining the maximum number of Shares available for delivery pursuant to Awards under the Plan; (ii) shares subject to an Award of Options or Stock-settled SARs (including any Option or Stock-settled SAR granted under the Prior Plan) that are not delivered to a Participant because such shares are used to satisfy an applicable tax withholding or exercise price obligation shall be deemed delivered hereunder and shall not again be available for delivery in connection with Awards; and (iii) shares subject to an Award other than an Option or Stock-settled SAR (including an Award granted under the Prior Plan) that are not delivered to a Participant because such shares are used to satisfy an applicable tax withholding obligation shall be deemed delivered hereunder and shall not again be available for delivery in connection with Awards. Shares purchased on the open market using the cash proceeds from the exercise of an Option (including any Option granted under the Prior Plan) shall not be added to the shares of Stock available for delivery hereunder in determining the maximum number of shares of Stock available for delivery pursuant to Awards under the Plan.
(d)    In no event shall the Company issue ISOs (as defined herein) under the Plan covering more than 2,538,690 shares of Stock (which number reflects the adjustment previously made in accordance with the Plan following the Company’s leveraged recapitalization with a special cash dividend completed on March 2, 2012), subject to adjustment as provided in Section 8.6 to the extent that such adjustment would not affect the qualification of such Awards as ISOs.
(e)    Awards granted through the assumption of, or in substitution or exchange for, similar awards in connection with the acquisition of another corporation or business entity shall not be counted for purposes of applying the limitations of this Section on numbers of shares of Stock available for Awards generally or any particular kind of Award under the Plan.
(f)    Stock delivered under the Plan may be either from authorized but unissued Stock, from treasury shares or from shares of Stock purchased in open-market transactions and private sales.
5.    ELIGIBILITY AND PARTICIPATION
    Employees, Directors, and Advisors, who in the opinion of the Committee are in a position to make a significant contribution to the success of the Company, its subsidiaries and affiliates, are eligible to receive Awards under the Plan. For purposes of the Plan, “Service” means the provision of services to the Company or its subsidiaries or affiliates in the capacity of (a) an Employee, (b) a Director, or (c) an Advisor. An “affiliate” for purposes of the Plan is an entity that controls, is controlled by or is under common control with, the Company. A “subsidiary” for purposes of the Plan is an entity in which the Company owns, directly or indirectly, equity interests possessing a majority of the total combined voting power of all classes of equity. The Committee will from time to time select the Employees, Directors and/or Advisors who are to be granted Awards.

- 3 -


6.    TYPES OF AWARDS
    6.1.    RESTRICTED STOCK AND RESTRICTED STOCK UNITS.
    (a)    Nature of Restricted Stock Awards. An Award of restricted stock entitles the recipient to acquire, at such time or times as the Committee may determine, shares of Stock subject to the restrictions described in paragraph (e) below (“Restricted Stock”).
    (b)    Nature of Restricted Stock Unit Awards. An Award of restricted stock units entitles the recipient to acquire, at such time or times as the Committee may determine, shares of Stock subject to the restrictions described in paragraph (e) below (“RSUs”). An RSU represents a contingent right to receive a Share or an amount equivalent in value to a Share.
    (c)    Payment for Restricted Stock Awards. The Committee may require, as a condition to an Award of Restricted Stock or RSUs, that a Participant deliver to the Company a purchase price in any amount set by the Committee for such Restricted Stock or RSUs.
    (d)    Rights as a Stockholder. A Participant who receives an Award of Restricted Stock will have all the rights of a stockholder with respect to the Stock, including voting and dividend rights, subject to the restrictions described in paragraph (f) below and any other conditions imposed by the Committee in the Award Agreement at the time of grant. The Award Agreement evidencing an Award of RSUs shall specify whether the Participant is entitled to any voting rights or to receive any dividends on the shares of Stock underlying the RSUs. Subject to Section 8.2, an Award of Restricted Stock or RSUs may provide for the right to receive Dividend Equivalents (as defined herein).
    (e)    Restrictions. The restrictions on each grant of Restricted Stock or RSUs will lapse at such time or times, and on such terms and conditions (including upon meeting pre-established performance goals), as the Committee may specify. Except as otherwise specifically provided by the Plan or by the Committee in any particular case, until these restrictions lapse, neither Restricted Stock nor RSUs may be sold, assigned, transferred, pledged or otherwise encumbered or disposed of. If the Participant’s Service terminates before such restrictions have lapsed, the Company shall have the right to repurchase the Restricted Stock for the amount of any consideration (excluding services) it received for the Restricted Stock plus, if the Committee shall so determine, an amount equal to the Withholding Requirements met by the Participant in connection with the sale of the Stock, or for such other consideration as the Committee shall determine, including for no consideration if no consideration other than services was paid for such Restricted Stock.
    (f)    Deferral. If a Participant so elects in accordance with such procedures as the Committee may specify from time to time, in accordance with the requirements of Section 409A of the Code and the interpretive guidance thereunder (“Section 409A”), the delivery of Restricted Stock and, if the deferral election so specifies, of the Dividend Equivalents with respect thereto, shall be deferred until the date or dates specified in such election.
    (g)    Section 83(b) Election. If a Participant, in connection with the acquisition of shares of Stock under the Plan or otherwise, makes an election under Section 83(b) of the Code, such Participant shall notify the Company within ten (10) days of filing notice of the election with the Internal Revenue Service or other governmental authority, in addition to any filing and notification required pursuant to regulations issued under Section 83(b) of the Code or any other applicable provision.

- 4 -


    6.2.    OPTIONS.
(a)    Nature of Options. An option is an Award entitling the recipient on exercise thereof to purchase shares of Stock at a specified exercise price (an “Option”). Both incentive stock options (as defined in Section 422 of the Code) (“ISOs”) and Options that are not ISOs may be granted under the Plan; provided that the Committee may award ISOs only to Employees.
(b)    Exercise Price. The exercise price of an Option shall be determined by the Committee and set forth in an applicable Award Agreement; provided, however, that the exercise price of an Option shall not be less than the Fair Market Value of a share of the Stock on the date the Option is granted (110% of the Fair Market Value of a share of Stock on the date of grant in the case of an ISO granted to an Employee who owns (within the meaning of Section 422(b)(6) of the Code) stock possessing more than ten percent of the total combined voting power of all classes of stock of the Company, or of a parent or a subsidiary (such person, a “Ten Percent Stockholder”)). For purposes of this Plan, “Fair Market Value” on any date means the closing sales price of the Stock on such date on the principal national securities exchange on which the Stock is listed or admitted to trading, or, if the Stock is not so listed or admitted to trading, the average of the per share closing bid price and per share closing asked price on such date as quoted on the National Association of Securities Dealers Automated Quotation System (“Nasdaq”) or such other market in which such prices are regularly quoted, or, if there have been no published bid or asked quotations with respect to shares on such date, the Fair Market Value shall be the value established by the Board in good faith and in accordance with Section 409A and, in the case of an ISO, Section 422 of the Code. Except for adjustment as provided in Section 8.6, any outstanding Option (i) shall not be repriced; (ii) shall not be canceled for the purpose of reissuing the Option to the Participant at a lower exercise price; and (iii) in the case of an Option that, at the time of cancellation, has an exercise price that exceeds the Fair Market Value of the underlying share of Stock, shall not be canceled for the purpose of exchanging the Option for any other Award and/or cash payment.
(c)    Duration of Options. The latest date on which an Option may be exercised will be the tenth anniversary of the date the Option was granted (five years in the case of an ISO granted to a Ten Percent Stockholder), or such earlier date as may have been specified by the Committee in the Award Agreement at the time the Option was granted.
(d)    Vesting and Exercise of Options. An Option will become vested and exercisable at such time or times, and on such terms and conditions (including upon meeting pre-established performance goals), as the Committee may specify in the Award Agreement for such Option. The Committee may at any time accelerate the time at which all or any part of the Option may be exercised.     
(e)    Exercise Procedures. Subject to the next following sentence, any exercise of an Option must be in writing, signed by the proper person and delivered or mailed to the Company, accompanied by (i) any documents required by the Committee and (ii) payment in full for the number of shares for which the Option is exercised. The exercise price for any Stock purchased pursuant to the exercise of an Option may, if permitted under the Award Agreement applicable to the Option, be paid in the following forms: (1) cash; (2) the transfer, either actually or by attestation, to the Company of shares of Stock that have been held by the Participant for at least six months (or such lesser period as may be permitted by the Committee) prior to the exercise of the Option, such transfer to be upon such terms and conditions as determined by the Committee; (3) by a “net exercise” arrangement, pursuant to which the number of shares of Stock issuable upon exercise of the Option shall be reduced by the largest whole number of shares of Stock having an aggregate Fair Market Value that does not exceed the aggregate exercise price (plus tax withholdings, if applicable); provided, however, that the Company shall accept a cash or other

- 5 -


payment from the Participant to the extent of any remaining balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares of Stock to be issued; (4) such other methods as the Committee makes available to Participants from time to time; or (5) a combination thereof. In addition, Options may be exercised through a registered broker-dealer pursuant to such cashless exercise procedures which are, from time to time, deemed acceptable by the Committee. Any shares of Stock transferred to the Company as payment of the exercise price under an Option shall be valued at their Fair Market Value on the day of exercise of such Option. If requested by the Committee, the Participant shall deliver the Award Agreement to the Secretary of the Company who shall endorse thereon a notation of such exercise and return such Award Agreement to the Participant. No fractional shares of Stock (or cash in lieu thereof) shall be issued upon exercise of an Option, and the number of shares of Stock that may be purchased upon exercise shall be rounded to the nearest number of whole shares. Notwithstanding any contrary provision of this Section 6.2, if, on the date an outstanding Option would expire (other than due to a termination of Service for Cause (as defined below)), the exercise of the Option, including by a “net exercise” or cashless exercise, would violate applicable securities laws or any insider trading policy maintained by the Company from time to time, the expiration date applicable to the Option will be extended to a date that is the earlier of (i) thirty (30) calendar days after the date the exercise of the Option would no longer violate applicable securities laws or any such insider trading policy and (ii) the expiration of the original term of the Option.
(f)    Exercise Limit. To the extent that the aggregate Fair Market Value (determined as of the date of the grant) of shares of Stock with respect to which ISOs granted under the Plan and “incentive stock options” (within the meaning of Section 422 of the Code) granted under all other plans of the Company or its subsidiaries (in either case determined without regard to this Section 6.2(f)) are exercisable by a Participant for the first time during any calendar year exceeds $100,000, such ISOs shall be treated as Options that are not ISOs. In applying the limitation in the preceding sentence in the case of multiple Options, Options that are intended to be ISOs shall be treated as Options which are not ISOs according to the order in which they were granted, such that the most recently granted Options are first treated as Options that are not ISOs.
(g)    ISO Exercise. An ISO must be exercised, if at all, within three months after the Participant’s termination of Service for a reason other than death or Disability and within twelve months after the Participant’s termination of Service for death or Disability. For purposes of this Plan, “Disability” is defined as permanent and total disability within the meaning of Section 22(e)(3) of the Code.
    6.3.    STOCK APPRECIATION RIGHTS.
(a)    Nature of Stock Appreciation Rights. A stock appreciation right is an Award entitling the recipient to receive upon exercise thereof payment of an amount determined by multiplying the excess of the Fair Market Value of a share of Stock on the date of exercise over the exercise price of the SAR, by the number of shares of Stock with respect to which the SAR is exercised (a “SAR”). The payment upon exercise of a SAR may be made in Stock, cash, or a combination of Stock and cash, as specified in the applicable Award Agreement.
(b)    Exercise Price. The exercise price of a SAR shall be determined by the Committee and set forth in an applicable Award Agreement; provided, however, that the exercise price of a SAR shall not be less than the Fair Market Value of a share of the Stock on the date the SAR is granted. Except for adjustment as provided in Section 8.6, any outstanding SAR (i) shall not be repriced; (ii) shall not be canceled for the purpose of reissuing the SAR to the Participant at a lower exercise price; and (iii) in the

- 6 -


case of a SAR that, at the time of cancellation, has an exercise price that exceeds the Fair Market Value of the underlying share of Stock, shall not be canceled for the purpose of exchanging the SAR for any other Award and/or cash payment.
(c)    Duration of SARs. The latest date on which a SAR may be exercised will be the tenth anniversary of the date the SAR was granted, or such earlier date as may have been specified by the Committee in the Award Agreement at the time the SAR was granted.
(d)    Exercise of SARs. A SAR will become exercisable at such time or times, and on such terms and conditions (including upon meeting pre-established performance goals), as the Committee may specify in the Award Agreement for such SAR. The Committee may at any time accelerate the time at which all or any part of the SAR may be exercised. Any exercise of a SAR must be in writing, signed by the proper person and delivered or mailed to the Company, accompanied by any documents required by the Committee. If requested by the Committee, the Participant shall deliver the Award Agreement to the Secretary of the Company who shall endorse thereon a notation of such exercise and return such Award Agreement to the Participant. No fractional shares of Stock (or cash in lieu thereof) shall be issued upon exercise of a SAR, and the number of shares of Stock that may be acquired upon exercise shall be rounded to the nearest number of whole shares.
6.4.    PERFORMANCE SHARES AND PERFORMANCE UNITS.
(a)    Nature of Performance Shares and Performance Units. A performance share is an Award with an initial value equal to the Fair Market Value of a share of Stock on the date of grant (a “Performance Share”), and a performance unit is an Award with an initial value determined by the Committee on the date of grant (a “Performance Unit”), in each case, that entitles the recipient to receive payment upon the attainment of performance goals and other terms and conditions determined by the Committee. Payment of Performance Shares or Performance Units may be made in Stock, cash, or a combination of Stock and cash, as specified in the applicable Award Agreement. In no event shall the amount of a Performance Unit payable to any Participant that is not denominated in shares of Stock and that is designed to qualify for the performance-based exception from the tax deductibility limitations of Section 162(m) of the Code exceed $5,000,000 for any calendar year.

(b)    Performance Goals. The Committee shall determine the number of Performance Shares or Performance Units, the length of the performance period, and the other terms and conditions of each Award.
    6.5.    CASH INCENTIVE AWARDS.
(a)     Nature of Cash Incentive Awards. A cash incentive award is an Award denominated in cash that entitles the recipient to an amount (payable in cash or a share-based Award as described below) upon the attainment of performance goals and other terms and conditions determined by the Committee, which may include annual performance goals and periods (“Cash Incentive Award”); provided, however, that in no event shall the amount of a Cash Incentive Award payable to any Participant that is designed to qualify for the performance-based exception from the tax deductibility limitations of Section 162(m) of the Code in accordance with Section 9 exceed $5,000,000 for any calendar year (whether payable in cash or in the form of a share-based Award). A Cash Incentive Award may be satisfied in cash or, if the

- 7 -


Committee so determines, by a grant of share-based Awards under the Plan with such terms and conditions as the Committee determines, or a combination of cash or share-based Awards.
(b)    Performance Goals. The Committee shall determine the amount of the Cash Incentive Award, the length of the performance period, and the terms and conditions of each Cash Incentive Award, including the form of payment.
    6.6    SUBSTITUTE AWARDS.
    (a)    In connection with any acquisition by the Company or any of its subsidiaries, the Committee may grant Awards to persons who became Employees, Directors or Advisors in connection with such acquisition in substitution for equity incentives held by them in the seller or acquired entity. In such case the Committee may set the prices and other terms of the substitute Awards at such amounts and in such manner as it, in its sole discretion, deems appropriate to preserve for the Participants the economic values of the equity incentives for which such Awards are substitutes (as determined by the Committee in its sole discretion) or otherwise to provide such incentives as the Committee may determine are appropriate.
    (b)    Unless required by applicable law, any substitute Awards granted pursuant to Section 6.6 shall not count toward the share limitations set forth in Section 4.
7.    EVENTS AFFECTING OUTSTANDING AWARDS
    7.1.    TERMINATION OF SERVICE.
    Unless otherwise set forth in an Award Agreement, an Award shall immediately terminate on the date a Participant’s Service terminates, and (a) any Options or SARs held by a Participant shall not be exercisable and all rights of the Participant with respect thereto shall immediately terminate, (b) any shares of Restricted Stock or RSUs with respect to which the restrictions have not lapsed shall be immediately forfeited and must be transferred to the Company in accordance with Section 6.1, and (c) any Performance Shares, Performance Units or Cash Incentive Awards shall be immediately forfeited.
    7.2    TERMINATION OF AWARD.
    The Company may terminate, cancel, rescind, recover, or revoke an Award immediately under certain circumstances, including, but not limited to a Participant’s:
    (a)    actions constituting “Cause”, which shall have the meaning provided under an employment, consulting or other agreement between a Participant and the Company, or if there is no such meaning provided under such agreement or no such agreement, shall include, but not be limited to, the: (i) conviction of or entering a plea of guilty or nolo contendere with respect to a crime, whether or not connected with the Company; (ii) commission of any act of fraud with respect to the Company; (iii) theft, embezzlement or misappropriation of any property of the Company; (iv) excessive absenteeism (other than as resulting from Disability); (v) failure to observe or comply with any Company work rules, policies, procedures, guidelines or standards of conduct which the Company has adopted for the regulation of the general conduct of its employees, as generally known to the employees of the Company or evidenced by the terms of any employee handbook, written memorandums or written policy statements; (vi) continued willful refusal to carry out and perform the material duties and responsibilities of a Participant’s position, excluding nonperformance resulting from Disability; or (vii) any other conduct

- 8 -


or act determined to be injurious, detrimental or prejudicial to any interest of the Company (in each case as determined in good faith by the Company);
    (b)    rendering of services for a competitor prior to, or within six (6) months after, the exercise of any Option or SAR or the termination of Participant’s Service with the Company;
    (c)    unauthorized disclosure of any confidential/proprietary information of the Company to any third party;
    (d)    failure to comply with the Company’s policies regarding the identification, disclosure and protection of intellectual property;
    (e)    violation of the Proprietary Rights Agreement/CMC Materials, Inc. Employee Confidentiality, Intellectual Property and Non-Competition Agreement for Employees signed by the Participant; or
    (f)    violation of the CMC Materials, Inc. Code of Business Conduct, including those provisions related to financial reporting.
    The existence of any such circumstances shall be determined in good faith by the Company.
    In the event of any termination, cancellation, rescission, recovery, or revocation, the Participant shall return to the Company any Stock received pursuant to an Award, or pay to the Company the amount of any gain realized on the sale of any such Stock, in such manner and on such terms and conditions as may be required, and the Company shall be entitled to set off against the amount of any such gain any amount owed to the Participant by the Company.
    7.3    CHANGE IN CONTROL.
    The Committee shall have the discretion to provide in applicable Award Agreements that, in the event of a “Change in Control” (as defined in Appendix A) of the Company, the following provisions will apply:
    (a)    Each outstanding Option or SAR (or such lesser portion of each Option or SAR as is set forth in an applicable Award Agreement) will immediately become exercisable in full.
    (b)    Each outstanding share of Restricted Stock or RSU (or such lesser number of shares as is set forth in an applicable Award Agreement) will immediately become free of the restrictions.
    (c)    The vesting of each Performance Share, Performance Unit, or Cash Incentive Award will immediately be accelerated, and the Participant will be paid in cash, Stock, or other property, as determined by the Committee, within thirty (30) days after the effective date of the Change in Control, a pro rata amount based on assumed achievement of all relevant performance measures at target levels, and upon the length of time within the applicable performance period that elapsed prior the effective date of the Change in Control; provided, however, that if the Committee determines that actual performance to the effective date of the Change in Control exceeds target levels, the prorated payouts will be made at levels commensurate with the actual performance (determined by extrapolating the actual performance to the end of the applicable performance period).

- 9 -


    (d)    In the event of a Change in Control that is a merger or consolidation in which the Company is not the surviving corporation or that results in the acquisition of substantially all the Company’s outstanding Stock by a single person or entity or by a group of persons or entities acting in concert, or in the event of a sale or transfer of all or substantially all of the Company’s assets (a “Covered Transaction”), the Committee shall have the discretion to provide for the termination of all outstanding Options or SARs as of the effective date of the Covered Transaction; provided, that, if the Covered Transaction follows a Change in Control or would give rise to a Change in Control, no Option or SAR will be so terminated (without the consent of the Participant) prior to the expiration of twenty (20) days following the later of (i) the date on which the Option or SAR became fully exercisable and (ii) the date on which the Participant received written notice of the Covered Transaction.
8.    GENERAL PROVISIONS
    8.1.    DOCUMENTATION OF AWARDS.
    Awards may be evidenced by written or electronic instruments prescribed by the Committee from time to time (each such instrument, an “Award Agreement”). Award Agreements may be in the form of agreements, to be executed by both the Participant and the Company, or certificates, letters or similar instruments, and may be provided in electronic form, acceptance of which will evidence agreement to the terms thereof and hereof.
    8.2.    RIGHTS AS A STOCKHOLDER; DIVIDEND EQUIVALENTS.
    Except as specifically provided by the Plan, the receipt of an Award will not give a Participant rights as a stockholder, and the Participant will obtain such rights, subject to any limitations imposed by the Plan or the Award Agreement, only upon actual receipt of Stock. However, the Committee may, on such conditions as it deems appropriate, provide in an Award Agreement that a Participant will receive a benefit in lieu of cash dividends that would have been payable on any or all Stock subject to the Participant’s Award had such Stock been outstanding. Without limitation, the Committee may provide for payment to the Participant of amounts representing dividends on such Award (other than Options and SARS) (such amounts, “Dividend Equivalents”), either currently or in the future, or for the investment of such amounts on behalf of the Participant; provided that the Committee shall design such payment to be exempt from or, in the alternative, comply with Section 409A; provided, further, that with respect to performance-based Awards, Dividend Equivalents shall not be paid until vesting (if any) of such Awards.
    8.3    CONDITIONS ON DELIVERY OF STOCK.
    The Company will not be obligated to deliver any shares of Stock, whether by electronic book entry or in certificate form, pursuant to the Plan or to remove any restriction from shares of Stock previously delivered under the Plan (a) until all conditions of the Award have been satisfied or removed, (b) until, in the opinion of the Company’s counsel, all applicable federal and state laws and regulations have been complied with, (c) if the outstanding Stock is at the time listed on any stock exchange, until the shares to be delivered have been listed or authorized to be listed on such exchange upon official notice of notice of issuance and (d) until all other legal matters in connection with the issuance and delivery of such shares have been approved by the Company’s counsel. If the sale of Stock has not been registered under the Securities Act of 1933, as amended, the Company may require, as a condition to exercise of the Award, such representations or agreements as counsel for the Company may consider appropriate to avoid violation of such Act and may require that the certificates evidencing such Stock bear an appropriate legend restricting transfer.

- 10 -


    8.4.    TAX WITHHOLDING.
    (a)    The Company may withhold from any payment made pursuant to an Award an amount as may be necessary and sufficient to satisfy all federal, state, local, and other applicable tax withholding requirements (the “Withholding Requirements”).
    (b)    The Committee will have the right to require that the Participant or other appropriate person remit to the Company an amount sufficient to satisfy the Withholding Requirements, or make other arrangements satisfactory to the Committee with regard to such requirements, prior to the delivery of any Stock. If and to the extent that any such withholding is required, the Committee may permit the Participant or such other person to elect at such time and in such manner as the Committee provides to have the Company hold back from the shares to be delivered, or to deliver to the Company, Stock having a value calculated to satisfy the Withholding Requirements. Notwithstanding anything herein to the contrary, the Committee may, in its sole discretion, permit a Participant to satisfy the Withholding Requirements by tendering shares of Stock having a Fair Market Value equal to the amount required to be withheld or such other greater amount up to the maximum statutory rate under applicable law, as applicable to such Participant, if such other greater amount would not result in adverse financial accounting treatment, as determined by the Committee (including in connection with the effectiveness of FASB Accounting Standards Update 2016-09).
    (c)    With respect to the exercise of ISOs, the Committee may require as a condition of exercise that the person exercising the ISO agree (i) to inform the Company promptly of any disposition of Stock received upon exercise of the ISO, and (ii) if the Company determines that it could be liable for Withholding Requirements with respect to a disposition of the Stock received upon exercise, to give such security as the Committee deems adequate to meet the potential liability of the Company for the Withholding Requirements and to augment such security from time to time in any amount reasonably deemed necessary by the Committee to preserve the adequacy of such security.
    8.5.    NONTRANSFERABILITY OF AWARDS.
    No Award shall be transferable by a Participant otherwise than by will or by the laws of descent and distribution or, except in the case of an ISO, pursuant to a domestic relations order (within the meaning of Rule 16a-12 promulgated under the Exchange Act), and an Option or SAR shall be exercisable during the lifetime of such Participant only by such Participant or such Participant’s executor or administrator or by the person or persons to whom the Option or SAR is transferred by will or the applicable laws of descent and distribution (such person, the Participant’s “Legal Representative”). Notwithstanding the foregoing sentence, the Committee may in a manner consistent with applicable law set forth in an Award Agreement evidencing an Award (other than an ISO) that the Award may be transferred to members of the Participant’s immediate family, to trusts solely for the benefit of such immediate family members and to partnerships in which such family members and/or trusts are the only partners, and for purposes of this Plan, such a transferee of an Award shall be deemed to be the Participant. For this purpose, “immediate family” shall refer only to the Participant’s spouse, parents, children, stepchildren and grandchildren and the spouses of such parents, children, stepchildren and grandchildren. The terms of an Award shall be final, binding and conclusive upon the beneficiaries, executors, administrators, heirs and successors of the Participant.

- 11 -


    8.6.    ADJUSTMENTS IN THE EVENT OF CERTAIN TRANSACTIONS.
    In the event of a merger, consolidation, acquisition of property or shares, stock rights offering, liquidation, disaffiliation of a subsidiary or affiliate, or similar event affecting the Company or any of its subsidiaries (each, a “Corporate Transaction”), the Committee or the Board may in its discretion make such substitutions or adjustments as it deems appropriate and equitable to (i) the aggregate number and kind of shares of Stock or other securities reserved for issuance and delivery under the Plan, (ii) the various maximum limitations set forth in Section 4 upon certain types of Awards and upon the grants to individuals of certain types of Awards, (iii) the number and kind of shares of Stock or other securities subject to outstanding Awards; and (iv) the exercise price of outstanding Options and SARs. In the event of a stock dividend, stock split, reverse stock split, separation, spinoff, reorganization, extra-ordinary dividend of cash or other property, share combination, or recapitalization or similar event affecting the capital structure of the Company (each, a “Share Change”), the Committee or the Board shall make such substitutions or adjustments as it deems appropriate and equitable to (A) the aggregate number and kind of shares of Stock or other securities reserved for issuance and delivery under the Plan, (B) the various maximum limitations set forth in Section 4 upon certain types of Awards and upon the grants to individuals of certain types of Awards, (C) the number and kind of shares of Stock or other securities subject to outstanding Awards; and (D) the exercise price of outstanding Options and SARs. In the case of Corporate Transactions, such adjustments may include, without limitation, (1) the cancellation of outstanding Awards in exchange for payments of cash, property or a combination thereof having an aggregate value equal to the value of such Awards, as determined by the Committee or the Board in its sole discretion (it being understood that in the case of a Corporate Transaction with respect to which stockholders of Stock receive consideration other than publicly traded equity securities of the ultimate surviving entity, any such determination by the Committee that the value of an Option or SAR shall for this purpose be deemed to equal the excess, if any, of the value of the consideration being paid for each share of Stock pursuant to such Corporate Transaction over the exercise price of such Option or SAR shall conclusively be deemed valid), provided, that in the event of the cancellation of such Awards pursuant to this clause (1), the Awards shall vest in full immediately prior to the consummation of such Corporate Transaction; (2) the substitution of other property (including, without limitation, cash or other securities of the Company and securities of entities other than the Company) for the shares of Stock subject to outstanding Awards; and (3) in connection with any disaffiliation of a subsidiary or affiliate, arranging for the assumption of Awards, or replacement of Awards with new awards based on other property or other securities (including, without limitation, other securities of the Company and securities of entities other than the Company), by the affected subsidiary, affiliate, or division or by the entity that controls such subsidiary, affiliate, or division following such disaffiliation of a subsidiary or affiliate (as well as any corresponding adjustments to Awards that remain based upon Company securities).
    8.7.    PARTICIPANT’S RIGHTS.
    Neither the adoption of the Plan nor the grant of Awards will confer upon any person any right to continued employment or Service with the Company or any subsidiary or affiliate or affect in any way the right of the Company any subsidiary or affiliate to terminate an employment or Service relationship at any time.
    8.8.    PAYMENT FOR STOCK; LOANS.
    Stock awarded under this Plan as Restricted Stock or received upon exercise of an Option or SAR may be paid for with such legal consideration as the Committee may determine. If and to the extent authorized by the Committee and permitted by applicable law, the Company may permit Participants to

- 12 -


pay for Stock with promissory notes, and may make loans to Participants of all or a portion of any Withholding Requirements to be met in connection with the grant, exercise or vesting of any Award. Any such extensions of credit may be secured by Stock or other collateral, or may be made on an unsecured basis, as the Committee may determine.
    8.9.    SUCCESSORS.
All obligations of the Company under the Plan or any Award Agreement will be binding on any successor to the Company, whether the existence of the successor results from a direct or indirect purchase of all or substantially all of the Company’s shares, or a merger, consolidation, or otherwise.
8.10.    SEVERABILITY.
If any provision of the Plan is held illegal or invalid for any reason, the illegality or invalidity will not affect the remaining parts of the Plan, and the Plan will be construed and enforced as if the illegal or invalid provision had not been included.
8.11.    REQUIREMENTS OF LAW.
The granting of Awards and the issuance of Share and/or cash payouts under the Plan will be subject to all applicable laws, rules, and regulations, and to any approvals by governmental agencies or national securities exchanges as may be required.
8.12.    SECURITIES LAW COMPLIANCE.
As to any individual who is, on the relevant date, an officer, director or ten percent beneficial owner of any class of the Company’s equity securities that is registered pursuant to Section 12 of the Exchange Act, all as defined under Section 16 of the Exchange Act, transactions under this Plan are intended to comply with all applicable conditions of Rule 16b-3 under the Exchange Act, or any successor rule. To the extent any provision of the Plan or action by the Board fails to so comply, it will be deemed null and void, to the extent permitted by law and deemed advisable by the Board.
8.13.    AWARDS TO FOREIGN NATIONALS AND EMPLOYEES OUTSIDE THE UNITED STATES.
To the extent the Board deems it necessary, appropriate or desirable to comply with foreign law or practice and to further the purposes of this Plan, the Board may, without amending the Plan, (i) establish rules applicable to Awards granted to Participants who are foreign nationals, are employed or providing Service outside the United States, or both, including rules that differ from those set forth in this Plan, and (ii) grant Awards to such Participants in accordance with those rules that would require the application of the law of any other jurisdiction.
8.14.    GOVERNING LAW.
To the extent not preempted by federal law, the Plan and all agreements hereunder will be construed and enforced in accordance with, and governed by, the laws of the State of Delaware, without giving effect to its conflicts of laws principles that would require the application of the law of any other jurisdiction. All references to statutory provisions and related regulatory provisions used herein shall include any similar or successor provisions. The jurisdiction and venue for any disputes arising under, or any action brought to enforce (or otherwise relating to), this Plan shall be exclusively in the courts in the State of Illinois, County of Cook, including the Federal Courts located therein (should Federal jurisdiction exist).

- 13 -


8.15    SECTION 409A COMPLIANCE.
(a)    Notwithstanding any provision of this Plan to the contrary, all Awards made under this Plan are intended to be exempt from or, in the alternative, comply with Section 409A and the interpretive guidance thereunder, including the exceptions for stock rights and short-term deferrals. The Plan shall be construed and interpreted in accordance with such intent. Each payment under an Award shall be treated as a separate payment for purposes of Section 409A. With respect to a Cash Incentive Award, the cash portion will be paid, and the grant of any portion payable as a share-based Award will be awarded, not later than March 15 of the calendar year following the calendar year in which the applicable performance period ended.
(b)    If a Participant is a “specified employee” (as such term is defined for purposes of Section 409A) at the time of his or her termination of Service, no amount that is nonqualified deferred compensation subject to Section 409A and that becomes payable by reason of such termination of Service shall be paid to the Participant (or in the event of the Participant’s death, the Participant’s representative or estate) before the earlier of (i) the first business day after the date that is six months following the date of the Participant’s termination of Service, and (ii) within 30 days following the date of the Participant’s death. For purposes of Section 409A, a termination of Service shall be deemed to occur only if it is a “separation from service” within the meaning of Section 409A, and references in the Plan and any Award Agreement to “termination of Service” or similar terms shall mean a “separation from service.” If any Award is or becomes subject to Section 409A, unless the applicable Award Agreement provides otherwise, such Award shall be payable upon the Participant’s “separation from service” within the meaning of Section 409A. If any Award is or becomes subject to Section 409A and if payment of such Award would be accelerated or otherwise triggered under a Change in Control, then the definition of Change in Control shall be deemed modified, only to the extent necessary to avoid the imposition of an excise tax under Section 409A, to mean a “change in control event” as such term is defined for purposes of Section 409A.
(c)    Any adjustments made pursuant to Section 8.6 to Awards that are subject to Section 409A shall be made in compliance with the requirements of Section 409A, and any adjustments made pursuant to Section 8.6 to Awards that are not subject to Section 409A shall be made in such a manner as to ensure that after such adjustment, the Awards either (i) continue not to be subject to Section 409A or (ii) comply with the requirements of Section 409A.
8.16    ERRONEOUSLY AWARDED COMPENSATION.
All Awards shall be subject to any incentive compensation recoupment or “clawback” policy established and amended from time to time by the Company, including any such policy established to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act, or as determined by the Company from time to time to comport with good corporate governance practices.

    8.17    UNFUNDED PLAN.

It is presently intended that the Plan shall be unfunded. Except for reserving a sufficient number of authorized shares of Stock, to the extent required by law to meet the requirements of the Plan, the Company shall not be required to establish any special or separate fund or to make any other segregation of assets to assure the delivery of shares of Stock relating to Awards granted pursuant to the Plan.


- 14 -


9.    QUALIFIED PERFORMANCE-BASED AWARDS.
    9.1    GRANT OF QUALIFIED PERFORMANCE-BASED AWARDS.
If the Committee makes Awards (other than Options or SARs) that are designed to qualify for the performance-based exception from the tax deductibility limitations of Section 162(m) of the Code and any regulations promulgated thereunder (a “Qualified Performance-Based Award”), such Awards shall be subject to the attainment of performance goals related to one or more of the following performance measures and business metrics: earnings before interest and taxes, earnings before interest, taxes, depreciation and amortization, stock price (including, but not limited to, growth measures and total stockholder return), revenue, net revenue, net revenue growth, gross margin, net income (before or after taxes), operating earnings or income, revenue backlog, economic value added, customer satisfaction, cost control or expense reduction, attainment of identified business opportunities, earnings per share, return on operating assets or capital, return on net assets, economic profit, appreciation in fair market value, volume/production, employee retention, cash flow (e.g., operating cash flow, free cash flow, discounted cash flow return on investment), market share, return to stockholders, cost management, business growth through market and technology extension, safety, improvement in technology and quality leadership, business processes, and organizational effectiveness and operational excellence, in each case, absolute or relative to a peer group or index.
9.2    PERFORMANCE GOALS
(a)    The performance goals established for the performance period established by the Committee shall be objective (as that term is described in regulations under Section 162(m) of the Code), and will be established in writing by the Committee not later than ninety (90) days after the beginning of the applicable performance period (but in no event after twenty-five percent (25%) of the performance period has elapsed), and while the outcome as to the performance goals is substantially uncertain. The performance goals established by the Committee will be based on one or more of the performance measures and business metrics set forth in Section 9.1 and any of such performance measures and business metrics may be used to measure the performance of the Company as a whole or of any business unit, division, acquired business, minority investment, partnerships or joint venture of the Company. The Committee may specify any reasonable definition of the performance measures and business metrics it uses. A Participant otherwise entitled to receive a Qualified Performance-Based Award for any performance period will not receive a settlement or payment of such Award until the Committee has determined that the applicable performance goals have been attained. The Committee may adjust in its sole discretion the performance goals applicable to any Awards to reflect any unusual or non-recurring events, including, but not limited to, exogenous events, financing activities, acquisitions, divestitures, recapitalizations (including stock splits and dividends), impact of charges for restructurings, discontinued operations, the cumulative effects of accounting or tax changes, and other items determined to be unusual in nature and/or infrequent in occurrence, each as defined by generally accepted accounting principles or as identified in the Company’s financial statements, notes to the financial statements, management’s discussion and analysis or other the Company’s filings with the Securities and Exchange Commission, provided that in the case of performance goals applicable to any Qualified Performance-Based Awards, such adjustment does not violate Section 162(m) of the Code. However, the Committee may not in any event increase the amount of compensation payable to a covered employee (within the meaning of Section 162(m) of the Code) upon attainment of a performance goal above the maximum amount approved by the Committee.


- 15 -


(b)    In the event that the Committee determines that it is advisable to grant Awards that may not qualify as Performance-Based Awards, the Committee may grant such Awards without satisfying the requirements of Section 162(m) of the Code, to the extent consistent with its other compensation objectives.
10.    DISCONTINUANCE, CANCELLATION, AMENDMENT AND TERMINATION
(a)    The Committee may at any time discontinue granting Awards under the Plan. The Board or the Committee may at any time or times amend the Plan or any outstanding Award, provided that no such amendment (other than an amendment made to comply with applicable law, including without limitation Section 409A, stock exchange listing standards or accounting rules) would materially impair the rights of a Participant with respect to a previously granted Award without such Participant’s consent. The Committee may at any time terminate the Plan as to any further grants of Awards. Except to the extent expressly required or permitted by the Plan, no amendment to the Plan or any outstanding Award will, without the approval of the stockholders of the Company, (a) increase the maximum number of shares available under the Plan, (b) extend the time within which Awards may be granted, (c) permit the Company to reprice any outstanding Option or SAR, (d) otherwise effect an action that would require stockholder approval under applicable law or the listing standards of Nasdaq or (e) amend the provisions of this Section 10, and no amendment or termination of the Plan may adversely affect the rights of any Participant (without his or her consent) under any Award previously granted.
(b)    Subject to the immediately preceding paragraph, the Committee, to the extent it deems necessary or advisable in its sole discretion, reserves the right, but shall not be required, to unilaterally amend or modify the Plan and any Award granted under the Plan so that the Award qualifies for exemption from or complies with Section 409A; provided, however, that the Committee makes no representations that Awards granted under the Plan shall be exempt from or comply with Section 409A and makes no undertaking to preclude Section 409A from applying to Awards granted under the Plan.

(the "Corporation") maintains the CMC Materials Short Term Incentive Program, which operates pursuant to, and according to the terms of, the CMC Materials, Inc. 2012 Omnibus Incentive Plan ("OIP"), (the "Program") to benefit and advance the interests of the Corporation by providing to the Corporation's employees performance-based cash bonuses ("Bonuses") that are based upon the achievement of financial, business and other performance goals.  Any Bonuses pursuant to the Program are Awards under the OIP.
Section 1.2.  Administration of the Program.  The Compensation Committee of the Corporation's Board of Directors (the "Committee") shall administer the Program.  The Committee may adopt such rules as it deems appropriate in order to carry out the purpose of the Program.  Questions of interpretation, administration and application of the Program shall be determined by the Committee.  The Committee may authorize any one or more of its members, or any officer of the Corporation, to execute and deliver documents on behalf of the Committee with respect to the Program.  The determinations of the Committee shall be final and binding in all matters relating to the Program.  The Committee shall have authority to determine the terms and conditions of Bonuses.   With the exception of any determination or payment of any Bonus to any Executive Officer of the Corporation (as defined by relevant Securities and Exchange Commission regulations), the Committee may delegate some or all of its authority under the Program to the Chief Executive Officer or other officers.
Section 1.3.  Eligible Persons.  Bonuses may be granted to employees of the Corporation.  The Committee or, if applicable, its delegate(s) shall determine the employees who are eligible to participate in the Program ("Participants").  An individual shall not be deemed an employee for purposes of the Program unless such individual is classified and receives compensation from the Corporation for services performed as an employee of the Corporation.
ARTICLE II. BONUSES
Section 2.1. Bonuses.  The Committee may grant annual Bonuses to employees subject to the provisions of the Program.
Section 2.2. Terms of Bonuses.  The Committee or, if applicable, its delegate(s) shall (i) establish for the relevant period of the Program ("Performance Period") the applicable performance goals and objectives ("Performance Objectives") for the Corporation and each Participant, and the particular allocation to each such Performance Objective, and (ii) establish target bonuses for each Participant, which shall equal a percentage of the Participant's base salary.  In general, for the Program, the Performance Period is the Corporation's fiscal year (October 1 – September 30).  Performance Objectives under the Program may include, but shall not be limited to, various financial, business and operational goals (for example, those related to earnings per share, revenue, gross margin, operating income, cash flow, earnings before interest and taxes, customer satisfaction, product quality, securing new opportunities, new product introductions, productivity improvements, customer return rate, and, new business area growth).
Section 2.3. Determination of Bonuses.  Following the close of the relevant Performance Period, the Committee, or, with respect to Participants other than Executive Officers, the Committee's delegate(s), shall determine the amount of Bonus (if any) to be paid to each Participant, based on assessment of achievement of the Performance Objectives of the Program, as well as reflecting an assessment of each Participant's individual performance or other factors during the relevant Performance Period, in the Committee's (or delegate(s)') sole discretion.  In no event shall a determination of a Bonus for an Executive Officer be made other than by the Committee.
Section 2.4. Payment of Bonuses.  Payment of a Bonus to a Participant shall be made as soon as practicable after determination of the amount of the Bonuses under Section 2.3 above, and after the Committee has approved the aggregate bonus payout amount for the Performance Period, and individual Bonuses for the Corporation's Executive Officers, but in no event later than 75 days after the end of the Performance Period.  In no event shall a payment of a



Bonus be made to an Executive Officer other than as specifically authorized by the Committee.  Participants whose employment is terminated, whether by the Corporation or voluntarily by the Participant, prior to the payment date of a Bonus shall not be entitled to receive a Bonus, whether or not a Bonus amount previously had been designated for such Participant pursuant to the terms of the Program.  According to the intent of the Corporation to award the entire accrual of Bonus amounts for the relevant Performance Period, which is set by the Committee in conjunction with the closing of the Corporation's financial books for such Performance Period, to the extent a Bonus amount had been accrued for and/or designated for such Participant in advance of the termination of such Participant's employment, the Corporation shall reallocate such amount to the pool of other Participants (with the exception of Executive Officers unless specifically agreed upon by the Committee) in the Program, to the extent administratively practical.

Section 2.5. Recovery of Bonuses.  The Corporation may rescind or recover a Bonus paid to a Participant immediately under certain circumstances, including, but not limited to, (i) the Participant's: actions constituting Cause, as determined by the Corporation in its discretion and as otherwise enforceable under local law; rendering of services for a competitor prior to, or within six (6) months after, the payment of a Bonus or the termination of Participant's Service with the Corporation; unauthorized disclosure of any confidential/proprietary information of the Corporation to any third party; failure to comply with the Corporation's policies regarding the identification, disclosure and protection of intellectual property; violation of the CMC Materials, Inc. Employee Confidentiality, Intellectual Property and Non-Competition Agreement; violation of the CMC Materials, Inc. Code of Business Conduct, including those provisions related to financial reporting, (2) and, as may be required by law, including regulations related to the Dodd-Frank Wall Street Reform and Consumer Protection Act.  In the event of any such rescission or right of recovery, the Participant must repay the Bonus to the Corporation, and the Company shall be entitled to set-off against the amount of the Bonus any amount owed to the Participant by the Corporation.
ARTICLE III  MISCELLANEOUS
Section 3.1. No Additional Participant Rights.  The participation of an employee in the Program shall not give such employee any right to be retained in the employ of the Corporation or any of its affiliates, and the Corporation specifically reserves the right to dismiss a Participant or to terminate any arrangement pursuant to which any such Participant provides services to the Corporation, with or without cause.  No person shall have claim to a Bonus under the Program, except as otherwise provided for herein, or to continued participation in the Program. There is no obligation for uniformity of treatment of Participants under the Program. The benefits provided for Participants under the Program shall be in addition to and shall in no way preclude other forms of compensation to or in respect of such Participants. It is expressly agreed and understood that the employment of a Participant is terminable at the will of either party and, if such Participant is a party to an employment agreement with the Corporation or one of its affiliates, in accordance with the terms and conditions of the Participant's employment agreement.
Section 3.2. No Assignment.  The rights of a Participant with respect to any Bonuses granted under the Program shall not be transferable by the Participant.
Section 3.3. Taxes; Tax Withholding.  To the extent a Participant who is to be paid a Bonus under the Program is subject to an employment arrangement with the Corporation or a subsidiary thereof that provides for tax equalization consideration, then such tax equalization consideration also shall apply to, and be included as part of, the Participant's Bonus to be paid under the Program.  The Corporation or a subsidiary thereof, as appropriate, shall have the right to deduct from all payments made under the Program to a Participant or to a Participant's beneficiary or beneficiaries any federal, state or local taxes required by law to be withheld with respect to such payments. Section
Section 3.4. No Restriction on Right of Corporation to Effect Changes.  The Program shall not affect in any way the right or power of the Corporation or its stockholders to make or authorize any recapitalization, reorganization, merger, acquisition, divestiture, consolidation, spin-off, combination, liquidation, dissolution, sale of assets, or other similar corporate transaction or event involving the Corporation or a subsidiary thereof or any other event or series of events, whether of a similar character or otherwise.
Section 3.5. Source of Payments.  The Corporation shall not have any obligation to establish any separate fund or trust or other segregation of assets to provide for payments under the Program. To the extent any person



acquires any rights to receive payments hereunder from the Corporation, such rights shall be no greater than those of an unsecured creditor. 
Section 3.6. Amendment and Termination.  The Committee may at any time and from time to time alter, amend, suspend or terminate the Program in whole or in part.
Section 3.7. Governing Law and Severability.  The Program and all rights and Bonuses hereunder shall be construed in accordance with and governed by the laws of the State of Illinois without regard to conflicts of law principles and applicable federal law.  The jurisdiction and venue for any disputes arising under, or any action brought to enforce (or otherwise relating to), the Program shall be exclusively in the courts in the State of Illinois, including the Federal Courts located therein (should Federal jurisdiction exist).  If any portion of the Program is deemed to be in conflict with local law, that portion of the Program, and that portion only, will be deemed null and void under that local law. All other provisions of the Program will remain in full effect.
Section 3.8.  Miscellaneous.  Notwithstanding any provision of the Program to the contrary, any and all Bonuses made under the Program are intended to be exempt from or, in the alternative, comply with Section 409A of the Internal Revenue Code of 1986, as amended, and the interpretive guidance thereunder, including the exceptions for short-term deferrals.  The Program shall be construed and interpreted in accordance with such intent.
