PART I

Item 1.  Business

Minerals Technologies Inc. (together with its subsidiaries, the "Company", “we”, “us” or “our”) is a resource- and technology-based company that develops, produces, and markets on a worldwide basis a broad range of specialty mineral, mineral-based and synthetic mineral products and supporting systems and services.

The Company has four reportable segments: Performance Materials, Specialty Minerals, Refractories and Energy Services.

The following table sets forth the percentage of our revenues generated from each segment for each of our last three fiscal years:

The Company maintains a research and development focus. The Company's research and development capability for developing and introducing technologically advanced new products has enabled the Company to anticipate and satisfy changing customer requirements, creating market opportunities through new product development and product application innovations.

Performance Materials Segment

The Performance Materials segment is a leading supplier of bentonite and bentonite-related products. Bentonite is a sedimentary deposit containing greater than 50% montmorillonite and is volcanic in origin. It is surface mined and then dried, crushed, sent through grinding mills where it is sized to customer requirements, and transferred to silos for automatic bagging or bulk shipment.  The processed bentonite may be chemically modified.  Bentonite’s unique chemical structure gives it a diverse range of capabilities, enabling it to act as a thickener, sealant, binder, lubricant or absorption agent.  There are two primary types of natural bentonite utilized by the business, sodium and calcium. Sodium-bentonite is characterized by its ability to absorb large amounts of water and form viscous, thixotropic suspensions.  Calcium-bentonite, in contrast, is characterized by its low water absorption and swelling capabilities and its inability to stay suspended in water. Each type of bentonite has its own unique applications.  This segment also supplies chromite and leonardite, which is primarily used in metalcasting, drilling fluid additive, and agricultural applications. The principal products of this segment are marketed under various registered trade names, including VOLCLAY^®, PANTHER CREEK^®, PREMIUM GEL^®, ADDITROL^®, PREMIUM CHOICE^®, ENERSOL^®, RAFINOL^® and Hevi-Sand^®.

In addition, the segment provides products for non-residential construction, environmental and infrastructure projects worldwide.  It serves customers engaged in a broad range of construction projects, including site remediation, concrete waterproofing for underground structures, liquid containment on projects ranging from landfills to flood control, and drilling applications including foundation, slurry wall, tunneling, water well, and horizontal drilling.

In the third quarter of 2020, the Company acquired the assets of a mining and hauling company in the western United States to support our bentonite clay mining operations.

The metalcasting product line produces custom-blended mineral and non-mineral products to strengthen sand molds for casting auto parts, farm and construction equipment, oil and gas production equipment, power generation turbine castings and rail car components.  These products help our customers in the foundry and casting industry to improve productivity by reducing scrap from metalcasting defects and poor surface quality.  The ADDITROL^® blends also improve the efficiency and recycling of sand blends in mold sand systems by lowering clay consumption and improve air quality by reducing volatile organic compound emissions.  Our mine to mold operational capability has resulted in providing a consistent high-quality product, technical support and reliable on-time delivery service valued by our customers.

In the ferrous casting market, the Company specializes in blending bentonite of various grades by themselves or with mineral binders containing sodium bentonite, calcium bentonite, seacoal and other ingredients.  In the steel alloy casting market, the Company sells chromite products with a particle size distribution specific to customers’ needs.  One of chromite’s qualities is its ability to conduct heat.  The Company markets the product for use in making very large, high integrity, steel alloy castings where the chromite is better suited to withstand the high heat and pressure associated with the casting process.

The Company is the exclusive distributor of certain specialty sand chromite products supplied by the Glencore-Merafe joint venture in select territories, including the Americas.  This product line was originally sold into the U.S. by the American Colloid Company (ACC) and over the past 90 years has grown in its use throughout the world including China, Thailand, Korea, Australia and Southeast Asia.  Over the past three years, the Company has focused on further investment in China and India.

The Company’s metalcasting product line net sales were $258.1 million, $291.2 million and $328.9 million for the years ended December 31, 2020, 2019 and 2018, respectively.

The household, personal care & specialty products product line contains pet litter, fabric care, health and beauty, basic minerals and agricultural and industrial specialty products.

The pet litter products include sodium bentonite-based scoopable (clumping), traditional and alternative cat litters sold to grocery and drug stores, mass merchandisers, wholesale clubs and pet specialty stores throughout North America, Europe and Asia. The Company’s scoopable products’ clump-forming capability traps urine, thereby reducing waste by allowing for easy removal of only the odor-producing elements from the litter box. The Company is a provider of private-label cat litter to retail partners, as well as a provider of bulk cat litter to national brands and other private label packaging companies. In North America, these products are sold from three principal sites from which we package and distribute finished goods, as well as ship bulk material via rail cars. The Company’s internal transportation group provides logistics services and is a key component of our capability in supplying customers on a national basis.  In Europe, these products are produced and sold by the Company's subsidiary, Sivomatic Holding, B.V. ("Sivomatic"). Sivomatic is a leading European supplier of premium pet litter products and is a vertically integrated manufacturer with production facilities in the Netherlands, Austria and Turkey.  Sivomatic is a certified CO₂ neutral producer of cat litter.

The Company supplies fabric care products and additives consisting of high-grade, agglomerated bentonite and other mineral additives that perform as softening agents in certain powdered-detergent formulations or act as carriers for colorants, surfactants and fragrances. These fabric care products are formulated to adapt to our customers’ changing technical requirements.

The Company manufactures personal care products consisting of polymer delivery systems and purified grades of bentonite ingredients for sale to manufacturers of skin care products. The polymers are used to deliver high-value active ingredients and the bentonite-based materials act as thickening, suspension and dispersion agent emollients for topical skin care formulations. The personal care products range from ingredient sales to fully formulated finished goods.

Specialty Materials include bentonite and leonardite based proprietary solutions for agricultural and industrial applications. Agricultural uses include crop harvest enhancements, natural animal heath feed additives and vegetable cooking oil clarification.

Basic minerals contains the sale of bentonite and leonardite to a variety of end markets and industrial applications, including Drilling Fluid Additives, Drilling Products and Other Industrial Products.

Drilling Fluid Additives are used in oil and gas well drilling. Bentonite imparts thickening and suspension properties that facilitate the transport of rock cuttings to the surface during the drilling process. It also contributes to a drilling fluid’s ability to lubricate the drill bit and coat the underground formations to prevent hole collapse and drill-bit seizing. Our primary trademark for this application is the trade name PREMIUM GEL^®.

Drilling products are used in environmental and geotechnical drilling applications, horizontal directional drilling, mineral exploration and foundation construction. The products are used to install monitoring wells, facilitate horizontal and water well drilling, and to seal abandoned exploration drill holes. The end-users for these products are typically small well drilling companies and general contractors.

The Company produces other industrial products utilizing bentonite and bentonite blends for the construction industry to be used as a plasticizing agent in cement, and plaster and bricks. The Company also supplies bentonite to help pelletize other materials for ease of use. An example of this application includes the pelletizing of iron ore.

This product line also includes sales from our internal transportation and logistics group.

The Company’s household, personal care & specialty products product line net sales were $380.2 million, $376.6 million and $348.5 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Specialty Minerals Segment

PCC Products and Markets

The Company's PCC product line net sales were $377.7 million, $434.0 million and $445.4 million for the years ended December 31, 2020, 2019 and 2018, respectively. The Company's sales of PCC have been, and are expected to continue to be, made primarily to the printing and writing papers segment of the paper industry and also into the packaging industry. The Company also produces PCC for sale to companies in the polymer, food and pharmaceutical industries.

In the paper industry, the Company's PCC is used:

The Company's Paper PCC product line net sales were $308.4 million, $364.9 million and $378.5 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Approximately 19% of the Company's sales consist of PCC sold to papermakers from "satellite" PCC plants. A satellite PCC plant is a PCC manufacturing facility located near a paper mill, thereby eliminating costs of transporting PCC from remote production sites to the paper mill. The Company believes the competitive advantages offered by improved economics and superior optical characteristics of paper produced with PCC manufactured by the Company's satellite PCC plants resulted in substantial growth in the number of the Company's satellite PCC plants since the first such plant was built in 1986. For information with respect to the locations of the Company's PCC plants as of December 31, 2020, see Item 2, "Properties," below.

The Company currently manufactures several customized PCC product forms using proprietary processes. Each product form is designed to provide optimum balance of paper properties including brightness, opacity, bulk, strength and improved printability. The Company's research and development and technical service staff focuses on expanding sales from its existing and potential new satellite PCC plants, as well as, developing new technologies for new applications. These technologies include, among others, acid-tolerant ("AT^®") PCC, which allows PCC to be introduced to the large wood-containing segment of the printing and writing paper market, OPACARB^® PCC, a family of products for paper coating, our FulFill^® family of products, a system of high-filler technologies that offers papermakers a variety of efficient, flexible solutions which decrease dependency on natural fibers, and NewYield^® and ENVIROFIL^®, innovative technologies that convert a paper and pulp mill waste stream into functional pigments for filling paper.

The Company owns, staffs, operates and maintains all of its satellite PCC facilities, and owns or licenses the related technology. Generally, the Company and its paper mill customers enter into long-term evergreen agreements, initially ten years in length, pursuant to which the Company supplies substantially all of the customer's precipitated calcium carbonate filler requirements. The Company is generally permitted to sell to third-parties PCC produced at a satellite plant in excess of the host paper mill's requirement.

The Company also sells a range of PCC products to paper manufacturers from production sites not associated with paper mills. These merchant facilities are located at Adams, Massachusetts and Lifford, United Kingdom.

Uncoated Wood-Free Printing and Writing Papers – North America. Beginning in the mid-1980's, as a result of a concentrated research and development effort, the Company's satellite PCC plants facilitated the conversion of a substantial percentage of North American uncoated wood-free printing and writing paper producers to lower-cost alkaline papermaking technology. The Company estimates that during 2020, more than 90% of North American uncoated wood-free paper was produced employing alkaline technology. Presently, the Company owns and operates 15 commercial satellite PCC plants located at paper mills that produce uncoated wood-free printing and writing papers in North America.

Uncoated Wood-Free Printing and Writing Papers – Outside North America. The Company estimates the amount of uncoated wood-free printing and writing papers produced outside of North America at facilities that can be served by satellite and merchant PCC plants is more than twice as large (measured in tons of paper produced) as the North American uncoated wood-free paper market currently served by the Company. The Company believes that the superior brightness, opacity and bulking characteristics offered by its PCC products allow it to compete with suppliers of ground limestone and other filler products outside of North America. Presently, the Company owns and operates 38 commercial satellite PCC plants located at paper mills that produce uncoated wood-free printing and writing papers outside of North America.  In addition, there is 1 plant currently under construction that will begin production in 2021.

Uncoated Groundwood Paper. The uncoated groundwood paper market, including newsprint, represents approximately 24% of worldwide paper production. Paper mills producing wood-containing paper still generally employ acid papermaking technology. The conversion to alkaline technology by these mills has been hampered by the tendency of wood-containing papers to darken in an alkaline environment. The Company has developed proprietary application technology for the manufacture of high-quality groundwood paper in an acidic environment using PCC (AT^® PCC). Furthermore, as groundwood or wood-containing paper mills use larger quantities of recycled fiber, there is a trend toward the use of neutral papermaking technology in this segment for which the Company presently supplies traditional PCC chemistries. The Company now supplies PCC at 4 groundwood paper mills around the world and licenses its technology to a ground calcium carbonate producer to help accelerate the conversion from acid to alkaline papermaking.

Coated Paper. The Company continues to pursue satellite PCC opportunities in coated paper markets where our products provide unique performance and/or cost reduction benefits to papermakers and printers. Our Opacarb^® product line is designed to create value to the papermaker and can be used alone or in combination with other coating pigments. PCC coating products are produced at 7 of the Company's PCC plants worldwide.

Specialty PCC Products and Markets

The Company also produces and sells a full range of dry PCC products on a merchant basis for non-paper applications. The Company's Specialty PCC product line net sales were $69.3 million, $69.1 million and $66.9 million for the years ended December 31, 2020, 2019 and 2018, respectively. The Company sells surface-treated and untreated grades of PCC to the polymer industry for use in automotive and construction applications, and to the adhesives and printing inks industries. The Company's PCC is also used by the food and pharmaceutical industries as a source of calcium in tablets and food applications, as a buffering agent in tablets, and as a mild abrasive in toothpaste. The Company produces PCC for specialty applications from production sites at Adams, Massachusetts and Lifford, England.

The Company mines and processes natural mineral products, primarily limestone and talc. The Company also manufactures lime, a limestone-based product. The Company's net sales of processed mineral products were $133.2 million, $140.4 million and $143.9 million for the years ended December 31, 2020, 2019 and 2018, respectively.  Net sales of ground calcium carbonate ("GCC") products, which are principally lime and limestone, were $89.3 million, $91.3 million and $91.0 million for the years ended December 31, 2020, 2019 and 2018, respectively.  Net sales of talc products were $43.9 million, $49.1 million and $52.9 million for the years ended December 31, 2020, 2019 and 2018, respectively.

The Company mines and processes GCC products at its reserves in the eastern and western parts of the United States. GCC is used and sold in the construction, automotive and consumer markets.

Lime produced at the Company's Adams, Massachusetts, and Lifford, United Kingdom, facilities is used primarily as a raw material for the manufacture of PCC at these sites and is sold commercially to various chemical and other industries.

The Company mines, beneficiates and processes talc at its Barretts site, located near Dillon, Montana. Talc is sold worldwide in finely ground form for ceramic applications and in North America for paint and coatings and polymer applications. Because of the exceptional chemical purity of the Barretts ore, a significant portion of worldwide automotive catalytic converter ceramic substrates contain the Company's Barretts talc.

Our high-quality limestone, dolomitic limestone, and talc products are defined primarily by the chemistry and color characteristics of the ore bodies. Ore samples are analyzed by x-ray fluorescence (XRF) and other techniques to determine purity and more generally by Hunter brightness measurement to determine dry brightness and the Hunter yellowness (b) value. We serve multiple markets from each of our operations, each of which has different requirements relating to a combination of chemical and physical properties.

Refractories Segment

The Company offers a broad range of monolithic and pre-cast refractory products and related systems and services. The Company's Refractory segment net sales were $258.1 million, $298.1 million and $311.9 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Refractory product sales are often supported by Company-supplied proprietary application equipment, laser measurement systems and on-site technical service support. The Company's proprietary application equipment is used to apply refractory materials to the walls of steel-making furnaces and other high temperature vessels to maintain and extend their useful life. Net sales of refractory products, including those for non-ferrous applications, were $212.3 million, $244.8 million and $261.1 million for the years ended December 31, 2020, 2019 and 2018, respectively. The Company's proprietary application systems, such as its MINSCAN^®, allow for remote-controlled application of the Company's refractory products in steel-making furnaces, as well as, in steel ladles. Since the steel-making industry is characterized by intense price competition, which results in a continuing emphasis on increased productivity, these application systems and the technologically advanced refractory materials developed in the Company's research laboratories have been well accepted by the Company's customers. These products allow steel makers to improve their performance through, among other things, the application of monolithic refractories to furnace linings while the furnace is at operating temperature, thereby eliminating the need for furnace cool-down periods and steel-production interruption. The result is a lower overall cost for steel produced by steel makers.

The Company's technical service staff and application equipment assist customers to achieve desired productivity objectives. The Company's technicians are also able to conduct laser measurement of refractory wear, sometimes in conjunction with robotic application tools, to improve refractory performance at many customer locations. The Company believes that these services, together with its refractory product offerings, provide it with a strategic marketing advantage.

Over the past several years, the Refractories segment has continued to develop, reformulate, and optimize its products and application technology to maintain its competitive advantage in the marketplace. Some of the products the Company has developed and optimized in the past include:

The principal market for the Company's refractory products is the steel industry. Management believes that certain trends in the steel industry will provide growth opportunities for the Company.

Raw Materials

The Company depends in part on having an adequate supply of raw materials for its manufacturing operations, particularly lime and carbon dioxide for the PCC product line, and magnesia and alumina for its Refractory operations. We also depend on having an adequate supply of bentonite and leonardite for our Performance Materials segment and limestone and talc for our Processed Minerals product line. Supplies of bentonite, leonardite, limestone and talc are provided through the Company’s own mining operations and we depend on having adequate access to ore reserves of appropriate quality at such mining operations.

The Company uses lime in the production of PCC and is a significant purchaser of lime worldwide. Generally, the lime utilized in our business is readily available from numerous sources and we purchase lime under long-term supply contracts from unaffiliated suppliers located in close geographic proximity to the Company's PCC plants. We also produce lime at our Adams, Massachusetts facility and our Lifford, UK facility, although most of the lime produced at our Adams facility and all of the lime produced at our Lifford facility is consumed in the production of Specialty PCC at the plant. We currently supply some quantities of lime to third parties that are in close proximity to our Adams plant and could supply small quantities of lime to certain of our PCC satellite facilities that are in close geographic proximity to the Adams plant. Carbon dioxide is readily available in exhaust gas from the host paper mills, or other operations at our merchant facilities.

The principal raw materials used in the Company's monolithic refractory products are refractory-grade magnesia and various forms of alumina silicates. Approximately 49% percent of the Company’s magnesia requirements were purchased from sources in China over the past five years. The price and availability of bulk raw materials from China are subject to fluctuations that could affect the Company's sales to its customers. In addition, the volatility of transportation costs has also affected the delivered cost of raw materials imported from China to North America and Europe. The Company has developed alternate sources of magnesia over the past few years that have reduced our reliance on China-sourced magnesia. The amount sourced from China and other locations can vary from year to year depending upon price and availability from each source. The alumina we utilize in our business is readily available from numerous sources. The Company also purchases calcium metal, calcium silicide, graphite, calcium carbide and various alloys for use in the production of metallurgical wire products and uses lime and aluminum in the production of calcium metal.

In addition to bentonite and leonardite provided through our mining operations, our Performance Materials segment’s principal raw materials are coal, soda ash, chromite, and woven and unwoven polyester material, all of which are readily available from numerous sources.

Mineral Reserves and Mining Process

The Company relies on access to bentonite reserves to support its Performance Materials segment. The Company has reserves of sodium and calcium bentonite at various locations in the U.S., including Wyoming, South Dakota, Montana and Alabama, as well as in Australia, China, and Turkey. Through the Company’s affiliations and joint ventures, the Company also has access to bentonite deposits in India, and Mexico. Assuming the continuation of 2020 annualized usage rates, the Company has reserves of commercially usable sodium bentonite for the next 51 years. Under the same assumptions, the Company has reserves of commercially usable calcium bentonite for the next 27 years. The Company owns or controls the properties on which the bentonite reserves are located through long-term leases, royalty agreements (including easement and right of way agreements) and patented and unpatented mining claims. No single or group of mining claims or leases is significant or material to the financial condition or operations of our Company or our segments. The majority of our current bentonite mining in the U.S. occurs on reserves where our rights to such reserves accrue to us through over 80 mining leases and royalty agreements and 2,000 mining claims. A majority of these are with private parties and located in Montana, South Dakota and Wyoming. The bentonite deposits underlying these claims and leases generally lie in parcels of land varying between 20 and 40 acres.

In general, our bentonite reserves are immediately adjacent to, or within sixty miles of, one of the related processing plants. All of the properties on which our reserves are located are either physically accessible for the purposes of mining and hauling or the cost of obtaining physical access would not be material. Access to processing facilities from the mining areas is generally by private road, public highways, or railroads. For most of our leased properties and mining claims, there are multiple means of access.

Bentonite is surface mined, generally with large earthmoving bulldozers and scrapers, and then loaded into trucks and off-highway-haul wagons for movement to processing plants. The mining and hauling of our bentonite is done by us and by independent contractors. At the processing plants, bentonite is dried, crushed and sent through grinding mills, where it is sized to customer requirements, then chemically modified, where needed, and transferred to silos for automatic bagging or bulk shipment. Most of the production is shipped as processed rather than stored for inventory.

For our Performance Materials segment, we also mine leonardite, a form of oxidized lignite, in North Dakota, and transport it to nearby processing facilities. Assuming the continuation of 2020 annualized usage rates, the Company has reserves of commercially usable leonardite for more than 30 years.

The Processed Minerals product line of our Specialty Minerals segment is supported by the Company's limestone reserves located in the western and eastern parts of the United States, and talc reserves located in Montana. The Company generally owns and surface mines these reserves and processes its products at nearby processing plants. The Company estimates these reserves, at current usage levels, to be in excess of 36 years at its limestone production facilities and in excess of 15 years at its talc production facility.

The Company has ongoing exploration and development activities for all of its mineral interests with the intent to increase its proven and probable reserves.

See Item 2, “Properties,” for more information with respect to these facilities and mines.

The Company relies on shipping bulk cargos of bentonite within and from the United States, Turkey and China to customers, as well as our own subsidiaries, and we are sensitive to our ability to recover these shipping costs. In the last few years, bulk cargo shipping rates have been very volatile, and, to a lesser extent, the availability of bulk cargo containers has been sporadic.

Competition

The Company is continually engaged in efforts to develop new products and technologies and refine existing products and technologies in order to remain competitive and to position itself as a market leader.

For the Performance Materials segment, the Company competes on the basis of product quality, service, technical support, price, product availability and logistics.  There are numerous major producers of competing products and various regional suppliers in the areas the Company serves. The Company is the world leader in bentonite, including number one positions in metalcasting and pet litter.  With respect to the environmental products product line, the Company competes with geosynthetic clay liner manufacturers worldwide, several suppliers of alternative lining technologies, and providers of soil and environmental remediation solutions and products. The building materials product line competes in a highly fragmented market comprised of a wide variety of alternative technologies. A number of integrated bentonite companies compete with our drilling products.

With respect to its PCC products, the Company competes for sales to the paper industry with other minerals, such as GCC and kaolin, based in large part upon technological know-how, patents and processes that allow the Company to deliver PCC that it believes imparts gloss, brightness, opacity and other properties to paper on an economical basis. The Company is the leading manufacturer and supplier of PCC to the paper industry.

The Company competes in sales of its limestone and talc based primarily upon quality, price, and geographic location.

With respect to the Company's refractory products, competitive conditions vary by geographic region. Competition is based upon the performance characteristics of the product (including strength, consistency and ease of application), price, and the availability of technical support.

The Energy Services segment competes with other oil and gas services companies. However, the Company believes that the Company offers several competitive advantages, especially in the area of water treatment services, due to superior and innovative technologies that the Company has developed internally and the combination of services that the Company can provide.

Seasonality

Some of our products in the Performance Materials segment within the environmental and building materials product lines are impacted by weather and soil conditions. Many of the products cannot be applied in wet or winter weather conditions and, as such, sales and profits tend to be greater during the period from April through October. As a result, we consider the business of this segment to be seasonal. Our Processed Minerals product line of our Specialty Minerals segment is subject to similar seasonal patterns.

Much of the business in the Energy Services segment can be impacted by weather conditions. Our business is concentrated in the Gulf of Mexico where our customers’ oil and gas production facilities are subject to natural disasters, such as hurricanes. Given this, our Energy Services sales could be lower in the June to November months.

Research and Development

Many of the Company's product lines are technologically advanced. The Company’s internal research team has dedicated years of experience into analyzing properties of minerals and synthetic materials while developing processes and applications to enhance their performance. Our expertise in inorganic chemistry, crystallography and structural analysis, fine particle technology and other aspects of materials science apply to and support all of our product lines. The Company's business strategy for growth in sales and profitability depends, to a large extent, on the continued success of its research and development activities.

The Company’s Performance Materials segment also offers a strong portfolio of custom blended compounds, formulations and technology, which have been primarily developed internally by the Company’s research and development efforts. The ADDITROL^® formulation, a custom blend, meets the need of both ferrous and non-ferrous applications. The Volclay^® application is used in green sand molding applications ranging from the production of iron and steel castings to the production of non-ferrous castings. The Hevi-Sand^® specialty chromite blend prevents metal penetration and can be used with most foundry binders in molds and cores. In addition, the Company’s RESISTEX^TM and CONTINUUM^® formulation enables withstanding aggressive leachates. The ORGANOCLAY^® technology offers highly effective solutions in effective in removing oils, greases and other high molecular weight, low solubility organic compounds from aqueous streams. The Company will also continue to seek out promising compounds and innovative technologies, developed mainly by our internal research team, to incorporate into our product lines.

In the Specialty Minerals segment, the significant achievements of the Company's research and development efforts include: the satellite PCC plant concept; PCC crystal morphologies for paper filling and coating; FulFill^® high filler technology systems; NewYield^® Waste Stream Process Technology; ENVIROFIL^® Waste Stream Process Technology; Thixocarb^® PCC, Vicality^® USP PCC, EMforce^®, and Optibloc^® for the Processed Minerals and Specialty PCC product lines.

The FulFill^® brand High Filler Technology is a portfolio of high-filler technologies that offers papermakers a variety of efficient, flexible solutions that decreases dependency on natural fiber and reduces costs. The FulFill® E and V series allows papermakers to increase filler loading levels of precipitated calcium carbonate (PCC), which replaces higher cost pulp, and increases PCC usage. Depending on paper grades, this PCC volume increase may range from 15 to 30 percent.  NewYield^® Waste Stream Process Technology cost-effectively converts a problematic pulp mill waste stream into a functional pigment for filling paper, eliminating the cost of environmental disposal and remediation of certain waste streams to papermakers. The product and technology have been validated on a commercial scale in a pulping operation and papermaking system in China, with several current projects underway. ENVIROFIL^® Waste Stream Process Technology cost-effectively converts a problematic de-inked sludge waste into a functional pigment for filling paper, eliminating the cost of environmental disposal and remediation.

In the Refractories segment, the Company’s achievements include the development of FASTFIRE^® and OPTIFORM^® shotcrete refractory products; LACAM^® laser-based refractory measurement systems; and the MINSCAN^® and HOTCRETE^® application systems. The Company will continue to reformulate its refractory materials to be more competitive.

For the years ended December 31, 2020, 2019 and 2018, the Company spent approximately $19.9 million, $20.3 million and $22.7 million, respectively, on research and development. The Company's research and development spending for 2020, 2019 and 2018 was approximately 1.2%, 1.1% and 1.3% of net sales, respectively.

The Company maintains its primary research facilities in Bethlehem and Easton, Pennsylvania; Houston, Texas; and Hoffman Estates, Illinois. It also has research and development facilities in China, England, Germany, Ireland, Japan and Turkey. Approximately 190 employees worldwide are engaged in research and development. In addition, the Company has access to some of the world's most advanced papermaking and paper coating pilot facilities.

Patents and Trademarks

The Company owns or has the right to use approximately 338 patents and approximately 1,706 trademarks related to its business.  Our patents expire between 2021 and 2037.  Our trademarks continue indefinitely.  The Company believes that its rights under its existing patents, patent applications and trademarks are of value to its operations, but no one patent, application or trademark is material to the conduct of the Company's business as a whole.

Insurance

The Company maintains liability and property insurance and insurance for business interruption in the event of damage to its production facilities and certain other insurance covering risks associated with its business. The Company believes such insurance is adequate for the operation of its business. There is no assurance that in the future the Company will be able to maintain the coverage currently in place or that the premiums will not increase substantially.

Human Capital Resources

Our people are the most important part of MTI.  They are the cornerstone of our operational excellence and safety-first culture, key to our ability to execute on our growth strategies, and vital to our success.  Our core values — people, excellence, honesty, customer focus and accountability — guide our actions.

Workforce Demographics

At December 31, 2020, the Company employed 3,566 persons globally, located in over 33 countries. Of these, 1,601 (45%) were located in North America, 895 (25%) were located in Europe, 903 (25%) were located in Asia and 167 (5%) were located in Latin America.

Diversity and Inclusion

As a global company, we are committed to a company culture that unconditionally accepts all colleagues. We are committed to reflecting the diversity of the communities where we live and work. By promoting and accepting our differences, we create an environment that supports better decision making, drives mutual respect and inspires collaboration.  We believe in the power of an environment where everyone feels involved, respected, valued and connected, where everyone is free to be their authentic selves and share ideas.  We also view diversity as key to leadership development. When selecting participants for internal development programs, we ensure that groups are balanced across a number of factors, including gender, ethnicity, tenure, function, geography and experience.

Compensation and Benefits

Focus on Safety

The health and safety of our employees is our number one core value.  We are committed to the health and safety of our employees, contractors, customers, and members of the communities in which we operate.  Our "safety first" culture has been built through dedication, continuous improvement and active engagement.  We continue to enhance our safety culture and our top priority is for all employees and contractors to return home in the same condition they arrived to work. While we believe zero-injuries across all our operations is attainable, we have set goals of 1.00 for Total Recordable Incident Rate (TRIR, which is the number of recordable injuries per 100 employees) and 0.10 for Lost Workday Injury Rate (LWIR, which is the number of lost workday injuries per 100 employees), and we continue to make strides to drive incidents below these levels.  In 2020, our TRIR was 0.60 and our LWIR was 0.22.  This safety-first mindset helps us attract and retain top talent from around the world and drives continuous improvement in our manufacturing operations.

The COVID-19 pandemic continues to impact lives and businesses around the world.  Protecting the health and safety of our employees is one of our core values.  Since the onset of the pandemic, we put in place a robust series of protocols to protect our employees while ensuring the safe and efficient operations of our facilities, including temporarily closing certain of our facilities; enhanced screening at entry to our facilities; restricting access at all facilities to business-critical visits; increasing cleaning and disinfecting protocols; use of personal protection equipment and additional hygiene supplies; adhering to social distancing guidelines; instituting remote work; restricting travel, and quarantining certain personnel.  Employees are continuing to work from home where possible.

Operational Excellence Culture

Our Operational Excellence (OE) journey, rooted in the active engagement of our employees, began more than a decade ago when we developed a comprehensive and highly structured business system of lean principles closely integrated with safe and reliable work practices. We’ve significantly advanced OE across all aspects of our company, fostering a culture of continuous improvement where each employee recognizes the importance of applying these people-focused principles and tools to solve challenges, constantly refine our processes, identify and remove risk and waste, and deliver value to our customers. Every day, MTI employees show their engagement and apply their skills in ways that deliver measurable outcomes and create both business and social value.

Talent Management

Our people are essential to the successful delivery of the MTI strategy and to sustaining superior business performance.  We believe our employees are at the core of everything we do.  The work environment at MTI continually evolves to maximize the employee experience and drive high performance.  We accelerate the development of our employees, strengthen our leadership capabilities, and enhance employee performance through engagement.  Our culture of training and development motivates employees at all levels of the organization to work safely and efficiently.  We employ several methods to engage, train and develop employees, yielding higher levels of performance year after year.   Investment in skills and acceleration of employees’ professional and personal development are essential components of our people strategy.  We leverage both formal and informal programs to identify, develop and retain talent across the organization. Through the MTI Internship Program, we identify new talent and prepare them for success within our organization upon graduation.  We also provide mentoring opportunities for rising talent in order to accelerate their development and improve our bench strength.  On a quarterly basis, the Leadership Council and Chief Executive Officer conduct an organizational and leadership review of all segments, business units and functional areas focusing on high performing and high potential talent, diverse talent and the succession plans for our most critical roles.  The various internship programs, development programs and succession planning sessions demonstrate the Company’s ongoing commitment towards accelerating development of our future leaders.

We use a variety of human capital measures in managing our business, including: workforce demographics; diversity metrics with respect to representation, attrition, hiring, promotions and leadership; and talent management metrics including retention rates of top talent and hiring metrics.

Environmental, Health and Safety Matters and Government Regulation

The Company’s operations are subject to federal, state, local and foreign laws and regulations relating to the environment and health and safety. In particular, we are subject to certain requirements under the Clean Air Act. In addition, certain of the Company’s operations involve and have involved the use and release of substances that have been and are classified as toxic or hazardous within the meaning of these laws and regulations. Environmental operating permits are, or may be, required for certain of the Company’s operations and such permits are subject to modification, renewal and revocation. We are also subject to land reclamation requirements relating to our mining operations.  In addition to environmental and health and safety laws and regulations, we are subject to a wide variety of other federal, state, local and foreign laws and regulations in the countries where we conduct business. The Company regularly monitors and reviews its operations, procedures and policies for compliance with these laws and regulations. Compliance with these laws and regulations often requires the dedication of time and effort of employees, as well as financial resources. The Company believes its operations are in substantial compliance with these laws and regulations and that there are no violations that would have a material effect on the Company. Despite these compliance efforts, some risk of environmental and other damage is inherent in the Company’s operations, as it is with other companies engaged in similar businesses, and there can be no assurance that material violations will not occur in the future. In fiscal 2020, compliance with the regulations applicable to us did not have a material effect on our capital expenditures, earnings, or competitive position, and the cost of compliance with these laws and regulations is not expected to have a material adverse effect on the Company in the future.

Sustainability is core to who we are and the foundation of how we operate our company. At MTI, we are focused on providing the safest workplace for our employees, creating innovative technologies tailored to our customers’ evolving demands, reducing our environmental impact, preserving natural resources and making positive contributions to our local communities — all of which are ingrained in our values. For the past 12 years, MTI has published an annual Corporate Responsibility and Sustainability Report that describes our efforts in continuous improvement regarding our safety culture, environmental performance, social impact, new product development, and community engagement. Over the past several years, we've taken meaningful steps to advance our broad range of sustainability initiatives, including establishing 2025 environmental reduction targets in six focus areas: Scope 1 and Scope 2 CO₂ emissions, airborne pollutants, water used, water discharged, and process waste landfilled.

Laws and regulations are subject to change. See Item 1A, Risk Factors, for information regarding the possible effects that compliance with new laws and regulations, including those relating to climate change, may have on our businesses and operating results.

Under the terms of certain agreements entered into in connection with the Company's initial public offering in 1992, Pfizer Inc. ("Pfizer") agreed to indemnify the Company against certain liabilities being retained by Pfizer and its subsidiaries including, but not limited to, pending lawsuits and claims, and any lawsuits or claims brought at any time in the future alleging damages or injury from the use, handling of or exposure to any product sold by Pfizer's specialty minerals business prior to the closing of the initial public offering.

Item 1A.  Risk Factors

Our business faces significant risks. Set forth below are all risks that we believe are material at this time.  Our business, financial condition and results of operations could be materially adversely affected by any of these risks.  These risks should be read in conjunction with the other information in this Annual Report on Form 10-K.

We have been and expect to continue to be adversely affected by the COVID-19 pandemic.

The COVID-19 outbreak, declared a pandemic by the World Health Organization, has surfaced in nearly all regions around the world. Governments around the world have taken preventative measures to contain or mitigate the outbreak, including travel restrictions, border closings, restrictions on public gatherings, shelter-in-place restrictions and limitations on business.  This has affected, and is continuing to affect, the global economy, the United States economy and the global financial markets.  The outbreak and resulting preventative measures have disrupted our operations and affected our business, and we expect this to continue.  The impacts include, but are not limited to, the following:

We cannot predict the degree to which, or the time period that, global economic conditions and our business, sales, liquidity, financial condition and results of operations will continue to be affected by the COVID-19 pandemic and the resulting preventative measures.  The extent to which we are affected will depend on future developments, including the duration of the outbreak, travel restrictions, business and workforce disruptions, and the effectiveness of actions taken to contain and treat the disease. The effects on our business, sales, liquidity, financial condition and results of operations could be material.

Worldwide general economic, business, and industry conditions may have an adverse effect on the Company’s results.

The global economic instability caused by the COVID-19 pandemic has caused and may continue to cause, among other things, declining consumer and business confidence, volatile raw material prices, instability in credit markets, high unemployment, fluctuating interest and exchange rates, and other challenges in the countries in which we operate. The Company’s business and operating results could be adversely affected by these global economic conditions. The Company’s customers and potential customers may experience deterioration of their businesses, cash flow shortages, and difficulty obtaining financing. As discussed below, the industries we serve have in the past been adversely affected by the uncertain global economic climate due to the cyclical nature of their businesses. As a result, existing or potential customers may reduce or delay their growth and investments and their plans to purchase products and may not be able to fulfill their obligations in a timely fashion. Further, suppliers could experience similar conditions, which could affect their ability to fulfill their obligations to the Company. Adversity within capital markets may also impact the Company’s results of operations by negatively affecting the amount of expense the Company records for its pension and other postretirement benefit plans. Actuarial valuations used to calculate income or expense for the plans reflect assumptions about financial market and other economic conditions – the most significant of which are the discount rate and the expected long-term rate of return on plan assets. Such actuarial valuations may change based on changes in key economic indicators. Global economic markets remain uncertain, and there can be no assurance that market conditions will improve in the near future. Future weakness in the global economy could materially and adversely affect our business and operating results.

Our customers’ businesses are cyclical or have changing regional demands. Our operations are subject to these trends and we may not be able to mitigate these risks.

Our Performance Materials segment’s sales are predominantly derived from the metalcasting market. The metalcasting market is dependent upon the demand for castings for automobile components, farm and construction equipment, oil and gas production equipment, power generation turbine castings, and rail car components. Many of these types of equipment are sensitive to fluctuations in demand during periods of recession or difficult economic conditions, including the current conditions resulting from the COVID-19 pandemic, which has affected and may continue to affect the demand for our Performance Materials segment’s products and services.

In the paper industry, which is served by our Paper PCC product line, production levels for uncoated freesheet within North America and Europe, our two largest markets are projected to continue to decrease. The reduced demand for premium writing paper products has also caused recent paper mill closures. We expect paper consumption to gradually improve, however remain below 2019 levels.

Our Refractories segment primarily serves the steel industry.  Global steel production has been and will continue to be affected by volatility in the market due to the COVID-19 pandemic.  We expect steel consumption to remain below 2019 levels but improved from 2020 levels.

Demand for our Energy Services segment’s products and services is affected by the level of exploration, development, and production activity of, and the corresponding capital spending by, oil and natural gas companies, which are heavily influenced by the benchmark price of these commodities. Oil and natural gas prices decreased significantly as a result of the COVID-19 pandemic with West Texas Intermediate (WTI) oil spot prices declining from a high of $63 per barrel in January 2020 to record low prices in April 2020. We expect that the volatility of oil prices, if sustained, will continue to cause oil and natural gas companies to reduce their capital expenditures and production and exploration activities. This has the effect of decreasing the demand and increasing competition for the services we provide. In addition, the performance of our Energy Services segment is affected by changes in technologies, locations of customers’ targeted reserves, and competition in various geographic markets.

Our Environmental Products and Building Materials products sales are predominantly derived from the commercial construction and infrastructure markets. In addition, our Processed Minerals and Specialty PCC product lines are affected by the domestic building and construction markets, as well as the automotive market.

Demand for our products is subject to trends in these markets. During periods of economic slowdown, our customers often reduce their capital expenditures and defer or cancel pending projects. Such developments occur even amongst customers that are not experiencing financial difficulties. In addition, these trends could cause our customers to face liquidity issues or bankruptcy, which could deteriorate the aging of our accounts receivable, increase our bad debt exposure and possibly trigger impairment of assets or realignment of our businesses. The Company has taken steps to reduce its exposure to variations in its customers' businesses, including by diversifying its portfolio of products and services; through geographic expansion, and by structuring most of its long-term satellite PCC contracts to provide a degree of protection against declines in the quantity of product purchased, since the price per ton of PCC generally rises as the number of tons purchased declines. In addition, many of the Company's product lines lower its customers' costs of production or increase their productivity, which should encourage them to use its products. However, there can be no assurance that these efforts will mitigate the risks of our dependence on these industries. Continued weakness in the industries we serve has had, and may in the future have, an adverse effect on sales of our products and our results of operations. A continued or renewed economic downturn in one or more of the industries or geographic regions that the Company serves, or in the worldwide economy, could cause actual results of operations to differ materially from historical and expected results.

The Company operates in very competitive industries, which could adversely affect our profitability.

The Company has many competitors. Some of our principal competitors have greater financial and other resources than we have. Accordingly, these competitors may be better able to withstand economic downturns and changes in conditions within the industries in which we operate and may have significantly greater operating and financial flexibility than we do. We also face competition for some of our products from alternative products, and some of the competition we face comes from competitors in lower-cost production countries like China and India. As a result of the competitive environment in the markets in which we operate, we currently face and will continue to face pressure on the sales prices of our products from competitors, which could reduce profit margins.

The Company’s sales could be adversely affected by consolidation in customer industries, principally paper, foundry and steel.

Several consolidations in the paper industry have taken place in recent years and such consolidation could continue in the future. These consolidations could result in partial or total closure of some paper mills where the Company operates PCC satellites. Such closures would reduce the Company's sales of PCC, except to the extent that they resulted in shifting paper production and associated purchases of PCC to another location served by the Company. Similarly, consolidations have occurred in the foundry and steel industries. Such consolidations in the major industries we serve concentrate purchasing power in the hands of a smaller number of manufacturers, enabling them to increase pressure on suppliers, such as the Company. This increased pressure could have an adverse effect on the Company's results of operations in the future.

The Company’s sales of PCC could be adversely affected by our failure to renew or extend long term sales contracts for our satellite operations.

The Company's sales of PCC to paper customers are typically pursuant to long-term evergreen agreements, initially ten years in length, with paper mills where the Company operates satellite PCC plants. Sales pursuant to these contracts represent a significant portion of our worldwide Paper PCC sales, which were $308.4 million in 2020, or approximately 19% of the Company’s net sales. The terms of many of these agreements have been extended or renewed in the past, often in connection with an expansion of the satellite plant. However, failure of a number of the Company's customers to renew or extend existing agreements on terms as favorable to the Company as those currently in effect, or at all, could have a substantial adverse effect on the Company's results of operations, and could also result in impairment of the assets associated with the PCC plant.

Servicing the Company’s debt will require a significant amount of cash. This could reduce the Company’s flexibility to respond to changing business and economic conditions or fund capital expenditures or working capital needs. Our ability to generate cash depends on many factors beyond our control.

At December 31, 2020 the Company had $952.7 million aggregate principal amount of total indebtedness (consisting primarily of $548.0 million aggregate principal amount of loans under our term facility and $400.0 million aggregate principal amount of notes) and an additional $290.5 million of borrowing capacity under the revolving credit facility (after giving effect to $9.5 million of outstanding letters of credit). Our outstanding indebtedness will require a significant amount of cash to make interest payments. Further, the interest rate on a significant portion of our borrowings under our senior secured credit facility is based on LIBOR interest rates, which could result in higher interest expense in the event of an increase in interest rates. In addition, since these borrowings under our senior secured credit facility extend beyond 2021, the interest rates for these obligations might be subject to change based on the United Kingdom's Financial Conduct Authority's intention to phase out LIBOR by the end of 2021. Our ability to pay interest on our debt and to satisfy our other debt obligations will depend in part upon our future financial and operating performance and upon our ability to renew or refinance borrowings. Prevailing economic conditions and financial, business, competitive, regulatory and other factors, many of which are beyond our control, will affect our ability to make these payments. We cannot guarantee that our business will generate sufficient cash flow from operations or that future borrowings will be available to us in an amount sufficient to enable us to fund our liquidity needs. If we are unable to generate sufficient cash flow to meet our debt service obligations, we will have to pursue one or more alternatives, such as reducing or delaying capital or other expenditures, refinancing debt, selling assets, or raising equity capital. Further, the requirement to make significant interest payments may reduce the Company’s flexibility to respond to changing business and economic conditions or fund capital expenditure or working capital needs and may increase the Company’s vulnerability to adverse economic conditions.

The agreements and instruments governing our debt contain various covenants that could significantly impact our ability to operate our business.

The agreement governing our senior secured credit facility and the indenture that governs our 5.0% Senior Notes due 2028 contain a number of significant covenants that, among other things, limit our ability to: incur or guarantee additional indebtedness, pay dividends or make other distributions or repurchase or redeem capital stock, prepay, redeem or repurchase certain debt, issue certain preferred stock or similar equity securities, make loans and investments, sell or otherwise dispose of assets, incur liens, enter into transactions with affiliates, enter into agreements restricting our subsidiaries’ ability to pay dividends and consolidate, merge or sell all or substantially all of our assets. In addition, our revolving credit facility, if used, requires us to comply with specific financial ratios, including a maximum net leverage ratio, under which we are required to achieve specific financial results. Our ability to comply with these provisions may be affected by events beyond our control. A breach of any of these covenants would result in a default under the applicable agreements. In the event of any default under our senior secured credit facility, our lenders could elect to declare all amounts borrowed under the credit agreement, together with accrued interest thereon, to be due and payable. In such an event, we cannot assure you that we would have sufficient assets to pay debt then outstanding under the credit agreement, the indenture governing our notes, and any other agreements governing our debt. Any future refinancing of the senior secured credit facility is likely to contain similar restrictive covenants. We may also incur future debt obligations that might subject us to additional restrictive covenants that could affect our financial and operational flexibility. We cannot assure you that we will be granted waivers or amendments to these agreements if for any reason we are unable to comply with these agreements or that we will be able to refinance our debt on terms acceptable to us, or at all.

The Company’s results could be adversely affected if it is unable to effectively achieve and implement its growth initiatives.

Sales and income growth of the Company depends upon a number of uncertain events, including the outcome of the Company's strategies of increasing its penetration into geographic markets such as Brazil, Russia, India and China as well as other Asian and Eastern European countries; increasing its penetration into product markets such as the market for papercoating pigments and the market for groundwood paper pigments; increasing sales to existing PCC customers by increasing the amount of PCC used per ton of paper produced; developing, introducing and selling new products such as the FulFill® family of products for the paper industry. Difficulties, delays or failure of any of these strategies could affect the future growth rate of the Company. Our strategy also anticipates growth through future acquisitions. However, our ability to identify and consummate any future acquisitions on terms that are favorable to us may be limited by the number of attractive acquisition targets, internal demands on our resources and our ability to obtain financing. Our success in integrating newly acquired businesses will depend upon our ability to retain key personnel, avoid diversion of management’s attention from operational matters, and integrate general and administrative services. In addition, future acquisitions could result in the incurrence of additional debt, costs and contingent liabilities. Integration of acquired operations may take longer, or be more costly or disruptive to our business, than originally anticipated, and it is also possible that expected synergies from future acquisitions may not materialize. We also may incur costs and divert management attention with regard to potential acquisitions that are never consummated.

Delays or failures in new product development could adversely affect the Company’s operations.

The Company’s future business success will depend in part upon its ability to maintain and enhance its technological capabilities, to respond to changing customer needs, and to successfully anticipate or respond to technological changes on a cost-effective and timely basis. The Company is engaged in a continuous effort to develop new products and processes in all of its product lines. Difficulties, delays or failures in the development, testing, production, marketing or sale of such new products could cause actual results of operations to differ materially from our expected results.

The Company’s ability to compete is dependent upon its ability to defend its intellectual property against inappropriate disclosure, theft and infringement.

The Company's ability to compete is based in part upon proprietary knowledge, both patented and unpatented. The Company's ability to achieve anticipated results depends in part on its ability to defend its intellectual property against inappropriate disclosure and theft as well as against infringement. In addition, development by the Company's competitors of new products or technologies that are more effective or less expensive than those the Company offers could have a material adverse effect on the Company's financial condition or results of operations.

The Company’s operations could be impacted by the increased risks of doing business abroad.

The Company does business in many areas internationally. Approximately 48% of our sales in 2020 were derived from outside the United States and we have significant production facilities which are located outside of the United States. We have in recent years expanded our operations in emerging markets, and we plan to continue to do so in the future, particularly in China, India, Brazil, the Middle East, and Eastern Europe. Some of our operations are located in areas that have experienced political or economic instability, including Indonesia, Malaysia, Nigeria, Egypt, Russia, Saudi Arabia, Turkey, Brazil, Thailand, China and South Africa. The UK’s decision to exit the European Union (referred to as Brexit) has caused additional volatility in the markets and currency exchange rates. Market conditions and exchange rates could continue to be volatile in the near term as this decision is implemented. As the Company expands its operations overseas, it faces increased risks of doing business abroad, including inflation, fluctuation in interest rates, changes in applicable laws and regulatory requirements, export and import restrictions, tariffs, nationalization, expropriation, limits on repatriation of funds, civil unrest, terrorism, unstable governments and legal systems, and other factors. We are also subject to increased risks of natural disasters, public health crises, including the occurrence of a contagious disease or illness, such as COVID-19, and other catastrophic events in such countries. Many of these risks are beyond our control and can lead to sudden, and potentially prolonged, changes in demand for our products, difficulty in enforcing agreements, and losses in the realizability of our assets. Adverse developments in any of the areas in which we do business could cause actual results to differ materially from historical and expected results. In addition, a significant portion of our raw material purchases and sales outside the United States are denominated in foreign currencies, and liabilities for non-U.S. operating expenses and income taxes are denominated in local currencies. Accordingly, reported sales, net earnings, cash flows and fair values have been and, in the future, will be affected by changes in foreign currency exchange rates. Our overall success as a global business depends, in part, upon our ability to succeed in differing legal, regulatory, economic, social and political conditions. We cannot assure you that we will implement policies and strategies that will be effective in each location where we do business.

The Company’s operations are dependent on the availability of raw materials and access to ore reserves at its mining operations. Increases in costs of raw materials, energy, or shipping could adversely affect our financial results.

The Company depends in part on having an adequate supply of raw materials for its manufacturing operations, particularly lime and carbon dioxide for the PCC product line, and magnesia and alumina for its Refractory operations. Purchase prices and availability of these critical raw materials are subject to volatility. At any given time, we may be unable to obtain an adequate supply of these critical raw materials on a timely basis, on price and other terms, or at all. While most such raw materials are readily available, the Company has purchased approximately 49% of its magnesia requirements from sources in China over the past five years. The price and availability of magnesia have fluctuated in the past and they may fluctuate in the future. Price increases for certain other of our raw materials, including petrochemical products, as well as increases in energy prices, have also affected our business. Our production processes consume a significant amount of energy, primarily electricity, diesel fuel, natural gas and coal. We use diesel fuel to operate our mining and processing equipment and our freight costs are heavily dependent upon fuel prices and surcharges. Energy costs also affect the cost of raw materials. On a combined basis, these factors represent a large exposure to petrochemical and energy products which may be subject to significant price fluctuations. The contracts pursuant to which we construct and operate our satellite PCC plants generally adjust pricing to reflect the pass-through of increases in costs resulting from inflation, including energy. However, there is a time lag before such price adjustments can be implemented. The Company and its customers will typically negotiate reasonable price adjustments in order to recover these escalating costs, but there can be no assurance that we will be able to recover increasing costs through such negotiations.

The Company also depends on having adequate access to ore reserves of appropriate quality at its mining operations. There are numerous uncertainties inherent in estimating ore reserves including subjective judgments and determinations that are based on available geological, technical, contract and economic information.

The Company relies on shipping bulk cargos of bentonite from the United States, Turkey and China to customers, as well as our own subsidiaries, and we are sensitive to our ability to recover these shipping costs. In the last few years, bulk cargo shipping rates have been very volatile, and, to a lesser extent, the availability of bulk cargo containers have been suspect. If we cannot secure our container requirements or offset additional shipping costs with price increases to customers, our profitability could be impacted. We are also subject to other shipping risks. In particular, rail service interruptions have affected our ability to ship, and the availability of rail service, and our ability to recover increased rail costs, may be beyond our control. During the COVID-19 pandemic, our ability to ship our products has been, and may in the future be, affected by government mandates in certain jurisdictions in which we operate.

The Company is subject to stringent regulation in the areas of environmental, health and safety, and tax, and may incur unanticipated costs or liabilities arising out of claims for various legal, environmental and tax matters or product stewardship issues.

The Company’s operations are subject to international, federal, state and local governmental environmental, health and safety, tax and other laws and regulations. We have expended, and may be required to expend in the future, substantial funds for compliance with such laws and regulations. In addition, future events, such as changes to or modifications of interpretations of existing laws and regulations, or enforcement polices, or further investigation or evaluation of the potential environmental impacts of operations or health hazards of certain products, may affect our mining rights or give rise to additional compliance and other costs that could have a material adverse effect on the Company. Government action taken in response to the COVID-19 pandemic, including government-imposed restrictions on the movement of people and goods, and other new legal rights and obligations, could also have an adverse effect on the Company. Further, certain of our customers are subject to various federal and international laws and regulations relating to environmental and health and safety matters, especially our Energy Services customers who are subject to drilling permits, waste water disposal and other regulations. To the extent that these laws and regulations affecting our customers change, demand for our products and services could also change and thereby affect our financial results. State, national, and international governments and agencies have been evaluating climate-related legislation and regulation that would restrict emissions of greenhouse gases in areas in which we conduct business, and some such legislation and regulation have already been enacted or adopted. Enactment of climate-related legislation or adoption of regulation that restrict emissions of greenhouse gases in areas in which we conduct business could have an adverse effect on our operations or demand for our products. Our manufacturing processes, particularly the manufacturing process for PCC, use a significant amount of energy and, should energy prices increase as a result of such legislation or regulation, we may not be able to pass these increased costs on to purchasers of our products. We cannot predict if or when currently proposed or additional laws and regulations regarding climate change or other environmental or health and safety concerns will be enacted or adopted.

The Company is also subject to income tax laws and regulations in the United States and various foreign jurisdictions. Significant judgment is required in evaluating and estimating our provision and accruals for these taxes. Our income tax liabilities are dependent upon the location of earnings among these different jurisdictions. Our income tax provision and income tax liabilities could be adversely affected by the jurisdictional mix of earnings, changes in valuation of deferred tax assets and liabilities and changes in tax treaties, laws and regulations.

The Company is currently a party in various litigation matters and tax and environmental proceedings and faces risks arising from various unasserted litigation matters, including, but not limited to, product liability, patent infringement, antitrust claims, and claims for third party property damage or personal injury stemming from alleged environmental torts. Failure to appropriately manage safety, human health, product liability and environmental risks associated with the Company’s products and production processes could adversely impact the Company’s employees and other stakeholders, the Company’s reputation and its results of operations. Public perception of the risks associated with the Company’s products and production processes could impact product acceptance and influence the regulatory environment in which the Company operates. While the Company has procedures and controls to manage these risks, carries liability insurance, which it believes to be appropriate to its businesses, and has provided reserves for current matters, which it believes to be adequate, an unanticipated liability, arising out of a current matter or proceeding or from the other risks described above, could have a material adverse effect on the Company’s financial condition or results of operations.

Production facilities are subject to operating risks and capacity limitations that may adversely affect the Company’s financial condition or results of operations.

The Company is dependent on the continued operation of its production facilities. During the COVID-19 pandemic, our facilities have been, and may in the future be, temporarily closed in response to government mandates in certain jurisdictions in which we operate or for the safety of our employees in response to positive diagnoses for COVID-19. Production facilities are subject to hazards associated with the manufacturing, handling, storage, and transportation of chemical materials and products, including pipeline leaks and ruptures, explosions, fires, inclement weather and natural disasters, mechanical failure, unscheduled downtime, labor difficulties, transportation interruptions, and environmental risks. We maintain property, business interruption and casualty insurance but such insurance may not cover all risks associated with the hazards of our business and is subject to limitations, including deductibles and maximum liabilities covered. We may incur losses beyond the limits, or outside the coverage, of our insurance policies. Further, from time to time, we may experience capacity limitations in our manufacturing operations. In addition, if we are unable to effectively forecast our customers’ demand, it could affect our ability to successfully manage operating capacity limitations. These hazards, limitations, disruptions in supply and capacity constraints could adversely affect financial results.

Operating results for some of our segments are seasonal.

Our operations have been and will continue to be subject to cyber-attacks that could have a material adverse impact on our business, consolidated results of operations, and consolidated financial condition.

Our operations are becoming increasingly dependent on digital technologies and services. We use these technologies for internal purposes, including data storage, processing, and transmissions, as well as in our manufacturing operations and in our interactions with customers and suppliers. Increased use of remote working arrangements has only increased our reliance on these technologies. Digital technologies are subject to the risk of cyber-attacks. If our systems for protecting against cybersecurity risks prove not to be sufficient, we could be adversely affected by, among other things: loss of or damage to intellectual property, proprietary or confidential information, or customer, supplier, or employee data; interruption of our business operations; and increased costs required to prevent, respond to, or mitigate cybersecurity attacks.

In October 2020, we detected a ransomware attack impacting certain of our information technology systems.  The network security incident primarily impacted our internal corporate functions.  The Company’s manufacturing sites, which rely on different networks, continued to operate safely and with limited interruption.  Further, we currently do not believe that any of our customers or suppliers were impacted as a result of this incident.  Nonetheless, we believe that the security event included unauthorized access to personal data of employees, former employees and their dependents.

The risks associated with the October 2020 incident or future incidents could harm our reputation and our relationships with customers, suppliers, employees, and other third parties, and may result in claims against us. In addition, although we do not currently believe the October 2020 incident will have a material impact on us, there can be no assurance that this incident or future incidents will not have a material adverse effect on our business, consolidated results of operations, and consolidated financial condition.

Item 1B.  Unresolved Staff Comments

None.

Item 2.  Properties

The Company’s corporate headquarters, sales offices, research laboratories, plants, mines and other facilities are owned by the Company except as otherwise noted. Set forth below is certain information relating to the Company’s principal plants and office and research facilities.

Set forth below is the location of, and the main customer served by, each of the Company's satellite PCC plants in operation or, under construction, within the Specialty Minerals segment, as of December 31, 2020. Generally, the land on which each satellite PCC plant is located is leased at a nominal amount by the Company from the host paper mill pursuant to a lease, the term of which generally runs concurrently with the term of the PCC production and sale agreement between the Company and the host paper mill.

(1)   These plants are owned through joint ventures.

(2)   This plant is under construction.

The following table sets forth, for each of the quarries or mines we own or operate, our current estimate as to the amount of proven and probable reserves such quarry or mine holds, based on the most recent mine plan, its usage rate in 2020, and a conversion factor for the conversion of in-situ materials to saleable products, by major mineral category.

*    Quantity of reserves that would be owned if patent was granted.

**  Unassigned reserves are reserves which we expect will require additional expenditures for processing facilities.

Our estimates of total reserves in the table above require us to make certain key assumptions. These assumptions relate to consistency of deposits in relation to drilling samples obtained with respect to both quantity and quality of reserves contained therein; the ratio of overburden to mineral deposits; any environmental or social impact of mining the minerals; and profitability of extracting those minerals, including haul distance to processing plants, applicability of minerals to various end markets and selling prices within those markets, and our past experiences in the deposits, several of which we have been operating in for many decades.

The Company believes that its facilities, which are of varying ages and are of different construction types, have been satisfactorily maintained, are in good condition, are suitable for the Company's operations and generally provide sufficient capacity to meet the Company's production requirements. Based on past loss experience, the Company believes it is adequately insured with respect to these assets and for liabilities likely to arise from its operations.

Item 3.  Legal Proceedings

The Company and its subsidiaries are involved in the legal and environmental proceedings described in Note 18 to the consolidated financial statements included elsewhere in this report, which disclosure is incorporated herein by reference. From time to time, the Company and its subsidiaries are also the subject of various routine legal actions and claims arising in the ordinary course of their businesses. The Company does not anticipate that the individual or aggregate liability arising out of litigation pending or claims known to be threatened against the Company and its subsidiaries will have a material adverse effect on the Company’s results of operations, cash flows or financial condition.

Item 4.  Mine Safety Disclosures

The information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95 to this Annual Report on Form 10-K.

Item 7.  Management's Discussion and Analysis of Financial Condition and Results of Operations

Cautionary Statement for “Safe Harbor” Purposes under the Private Securities Litigation Reform Act of 1995

The Private Securities Litigation Reform Act of 1995 provides a safe harbor for forward-looking statements made by or on behalf of the Company. This report contains statements that the Company believes may be “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, particularly statements relating to the Company’s objectives, plans or goals, future actions, future performance or results of current and anticipated products, sales efforts, expenditures, and financial results. From time to time, the Company also provides forward-looking statements in other publicly-released materials, both written and oral. Forward-looking statements provide current expectations and forecasts of future events such as new products, revenues and financial performance, and are not limited to describing historical or current facts. They can be identified by the use of words such as “outlook,” “forecast,” “believes,” “expects,” “plans,” “intends,” “anticipates,” and other words and phrases of similar meaning.

Forward-looking statements are necessarily based on assumptions, estimates and limited information available at the time they are made. A broad variety of risks and uncertainties, both known and unknown, as well as the inaccuracy of assumptions and estimates, can affect the realization of the expectations or forecasts in these statements. Many of these risks and uncertainties are difficult to predict or are beyond the Company’s control. Consequently, no forward-looking statements can be guaranteed. Actual future results may vary materially. Significant factors affecting the expectations and forecasts are set forth under “Item 1A — Risk Factors” in this Annual Report on Form 10-K.

The Company undertakes no obligation to update any forward-looking statements to reflect events or circumstances that arise after the date hereof. Investors should refer to the Company's subsequent filings under the Securities Exchange Act of 1934 for further disclosures.

Executive Summary

Worldwide sales decreased 11% in 2020 to $1.595 billion as compared with $1.791 billion in 2019.  Foreign exchange had an unfavorable impact on sales of $16 million or 1%.  Consolidated income from operations was $187.9 million as compared with $208.7 million in the prior year.  Included in income from operations for 2020 was $10.4 million related to litigation expenses associated with the bankruptcy of Novinda Corp, $7.6 million for assets write-downs and severance-related costs, $3.1 million of acquisition-related expenses and $4.0 million in costs related to system restoration and risk mitigation following a ransomware attack on certain of the Company's information technology systems.  Included in income from operations in 2019 were restructuring and other items of $13.2 million and a $10.9 million charge related to litigation expenses associated with the bankruptcy of Novinda Corp.  Net income was $112.4 million in 2020, as compared to $132.7 million in the prior year.  The Company reported diluted earnings of $3.29 per share in 2020 as compared with $3.78 per share in the prior year.

In March 2020, the World Health Organization categorized the novel coronavirus (COVID-19) as a pandemic. We have remained focused on the health and safety of our employees, and deployed rigorous health, safety and wellness protocols for all of our facilities in order to protect our employees.  We have also conducted scenario planning and developed contingency plans to ensure we are supporting our customers and adjusting to changing market dynamics. Around the world, the Company continues to closely adhere to all government regulations as they are issued. Applicable governmental directives across the United States and other global locations have typically permitted the continued operation of essential critical infrastructure sectors. As the Company supplies products and services to many essential industries, including critical manufacturing and energy sectors, all of our operations had qualified as essential businesses. Accordingly, all of the Company’s production facilities are currently operational. In a few locations, however, sites were temporarily impacted by the pandemic during 2020.

The economic environment related to the COVID-19 pandemic, which slowed business activity in several key end-markets, negatively impacted the Company’s results in 2020. The pandemic has affected and may continue to affect the demand for a number of our Performance Materials segment’s products and services. Paper consumption has been and may continue to be impacted. Global steel production has been and may continue to be affected by volatility in the market due to the pandemic, which could impact our Refractory segment. Oil and natural gas prices have been volatile as a result of the pandemic, and this could cause oil and natural gas companies to reduce their capital expenditures and production and exploration activities.

The impacts of the COVID-19 pandemic may continue to impact our results during 2021. The extent to which our operations will be impacted by the pandemic will depend largely on future developments, including the continued severity of the pandemic and future actions by government authorities to contain it or treat its impact. These conditions are highly uncertain and cannot be accurately predicted.  We will continue to actively monitor and respond to the evolving situation.

In 2020, the Company continued to execute on its growth strategies of geographic expansion and new product innovation. The Company delivered sales growth across several product lines and geographies, increased volumes through capacity expansions and a new PCC satellite facility, and capitalized on customer demand for our latest innovative products.

Long-term debt as of December 31, 2020 was $933.2 million.  On June 30, 2020, the Company issued $400 million aggregate principal amount of 5.0% Senior Notes due 2028. The net proceeds were used to repay $148 million of fixed rate term loans and $100 million of outstanding borrowing under its revolving credit facility and the remainder for general corporate purposes. Additionally, in 2020, we repurchased $40.7 million of treasury shares.

Our balance sheet continues to be strong.  Cash, cash equivalents and short-term investments were $371.8 million as of December 31, 2020.  Cash flow from operations for 2020 was $240.6 million.  The Company currently has more than $650 million of available liquidity, including cash on hand, as well as availability under its revolving credit facility. We believe these factors will allow us to meet our anticipated funding requirements. Our intention is to maintain a balanced approach to capital deployment, by using excess cash flow for investments in growth, continued debt reduction and selective share repurchases.

Outlook

The COVID-19 pandemic had an adverse effect on our reported results for 2020, and may continue to negatively impact our business and results of operations for 2021.  The extent to which our operations will be impacted by the pandemic will depend largely on future developments, including the severity of the pandemic and actions by government authorities to contain it or treat its impact. These are highly uncertain and cannot be accurately predicted.  We will continue to actively monitor and respond to the COVID-19 pandemic.

The Company will continue to focus on innovation and new product development and other opportunities for sales growth in 2021 from its existing businesses, as follows:

However, there can be no assurance that we will achieve success in implementing any one or more of these opportunities.
