2020

A Message From Our  
Chairman & CEO
DOUGLAS T. DIETRICH

2020 tested the strength and capabilities of our company in many ways. 
Despite numerous challenges related to the COVID-19 pandemic, the solid 
results we achieved underscore the power of our operating culture, the 
resiliency of our global market-leading positions, the value we provide to 
our customers, and the strength of our financial foundation. The year also 
presented new opportunities, including leveraging virtual tools, to adapt  
and rise to the needs and expectations of our employees, customers, 
communities, and shareholders. 

I am constantly impressed by our talented employees and their focus on  
our values, including operating safely, maintaining a continuous improvement 
mindset in everything we do, and serving our customers. These qualities were 
clearly demonstrated in the face of the pandemic, and I am thankful to our 
employees for their focus, efforts, and perseverance. 

Before I cover our performance in 2020, I want to briefly outline the priorities  
we set to guide MTI during the year:

Protect the health, safety and well-being of 
MTI’s 3,500 plus employees and their families 
and the communities where we work;

Ensure business continuity and efficiently 
operate our facilities; 

Serve our customers in essential industries 
with value-added products;

Generate strong cash flow to support  
our financial position; 

Continue to advance our growth initiatives; 

Diligently manage our costs; and

Position MTI to emerge through the crisis  
as a stronger company.

Taken together, these priorities have ensured MTI is there for our employees, customers, and 
communities, and that we are delivering sustained value to our shareholders. As we adjusted to a 
new reality, and successfully managed through difficult circumstances, MTI exited 2020 in a stronger 
position than when we began the year.

Chairman & CEO

DOUGLAS T. DIETRICH

SUPPORTING OUR PEOPLE AND COMMUNITIES  
DURING THE PANDEMIC 

We established a COVID-19 task force to guide all the key 
activities in a coordinated manner and ensure business 
continuity. Based on learnings from our experience in China  
in the beginning of the year, we implemented a series of robust 
protocols for MTI employees across our global locations, 
including temperature scans, increased disinfection, social  
distancing, and the use of masks. We recognized early  
on that we needed to educate and train our teams and  
their families about the risks of community spread  
and how our safe work practices could be extended  
to their homes. By doing so, our employees have not  
only had the resources to protect themselves and their 
colleagues, but also their families and local communities. 

Over the past year,  
I have been inspired  
by the dedication, 
flexibility, and 
collaboration from our 
employees across the 
globe. Protecting the 
health and safety of our 
employees is one of our 
core values, and this  
was particularly critical  
in 2020. 

We took several proactive steps to support our employees and address their needs during this time, including a special 

bonus payment to recognize our frontline employees for their efforts, pay continuity for employees unable to work due 

to COVID-19 and government mandated shutdowns, and through an Employee Assistance Program offering services 

from financial counseling to mental health support.

While working in a challenging and distracting environment, our employees stayed focused on improving our safety 

performance, which resulted in the lowest recordable injury rate in MTI’s history. It is a testament to the strength of our 

people, capabilities, and processes that we were able to swiftly adapt to the new working environment and drive our 

safety culture forward.

A MESSAGE FROM OUR CEO

MANAGING THROUGH CHANGING CONDITIONS  
TO DELIVER SOLID RESULTS

The resiliency of our differentiated business model 
and our team’s execution focus and ability to quickly 
adapt were evident throughout 2020. Conditions in our 
end markets were dynamic with our consumer-oriented 
businesses experiencing resilient demand while demand 
in others dropped dramatically. With our diverse sales 
portfolio balanced across sectors and geographies,  
we were able to effectively mitigate the impact. 

Our consumer-oriented businesses in both Performance 
Materials and Specialty Minerals were consistently 
strong during the year. As volumes in our businesses 
serving industrial end markets were impacted most 
notably in the second quarter, we made several 
operational adjustments at our plants, including value-
added maintenance activities and manufacturing 
process improvements.

Leveraging our global 
manufacturing footprint, unique 
capabilities, and customer-focus, 
we strengthened our positions 
with existing customers and 
captured opportunities with  
new ones. 

When our industrial markets, including 
automotive, residential construction, 
and steel, steadily improved in the last 
four months of the year, we were well 
positioned to deliver strong earnings 
performance on the higher volumes.

BILLION REVENUE  
MILLION OPERATING INCOME*

We took aggressive measures to enhance our operational 
efficiency, including variable cost adjustments and structural 
overhead savings. In addition, we drove productivity 
improvements, continued with pricing actions, and increased 
our sales of new products. Through these efforts we were well-
positioned to leverage improving sales in the latter part of the 
year into income, which resulted in higher overall operating and 
EBITDA margins compared to 2019.

CULTURE OF CONTINUOUS IMPROVEMENT:  
AGILE OPERATING MODEL 

Operational Excellence, which is our deeply ingrained  
business system focused on lean principles and operating 
in the least waste way, was a critical factor in our ability to 
manage through the obstacles we faced. Our people and  
their engagement in the company are what drive this mindset 
and it is the unique recipe for MTI to be agile. We conducted 
8,600 problem-solving kaizen events and received over  
63,000 suggestions from our employees on how to  
improve our daily processes. This is a significant level  
of engagement from all MTI employees — a clear  
demonstration of the power of our continuous  
improvement culture.

NEW VIRTUAL TOOLS ENHANCE ENGAGEMENT WITH CUSTOMERS  
AND ENABLE INTERNAL COLLABORATION AND EFFICIENCIES

The pandemic proved to be a time when our customers needed us most, and we transformed our processes 
and capabilities to drive efficiencies, improve collaboration, and further demonstrate our value proposition 
through a variety of virtual tools. Examples include:

Performing 
specialized 
maintenance 
assessments  
without engineers 
physically present  
at the plant

Remote 
commissioning 
of new PCC 
satellites and 
customer visits

Supporting 
trialing and

new products  
and applications

Developed a virtual 
webinar series  
that allows our technical 
teams to interact with 
a broader group of 
customers and more 
quickly provide them with 
our value-added solutions 

In addition to making changes to serve our customers, our virtual capabilities have helped to drive efficiencies  
in our internal processes, improve the speed of decision making, and increase connectivity and collaboration  
with our global teams through remote site visits and meetings. These tools are becoming a significant 
competitive advantage to our company and will remain a permanent part of how we work in the future.

A MESSAGE FROM OUR CEO

ADVANCING OUR GROWTH INITIATIVES 

Despite the challenging circumstances in 2020, we remained focused on executing our growth strategy,  
and we made progress on several fronts throughout the year. 

GEOGRAPHIC EXPANSION

lines through market 
penetration and entering 
higher-growth areas

NEW PRODUCT 
DEVELOPMENT

Our growth initiatives are supported by a strong and flexible balance sheet which provides  
the ability to generate attractive, sustainable returns for shareholders.

GROWING OUR CONSUMER-ORIENTED 
PORTFOLIO 

For several years, we have been focused on growing our 
consumer-oriented businesses in both Performance Materials 
and Specialty Minerals as these are high-return areas with 
steady growth potential. We are uniquely positioned to serve 
these markets and have invested in strengthening our vertically 
integrated capabilities, resources, and new technologies. Much  
of the strength has been in our global Pet Care business as  
we continue to grow our portfolio of premium products, enter  
new channels such as e-commerce, and expand our presence  
in Europe and Asia. In addition, we delivered solid increases  
in personal care, edible oil purification, fabric care, and other  
food and pharmaceutical applications. 

METALCASTING PENETRATION IN ASIA

Our Metalcasting business is a key growth area for MTI as we build on 
our position as the leader in greensand bond systems for the global 
foundry market. There are significant opportunities to leverage our 
extensive technical expertise and cost and quality value proposition 
with customers in large foundry markets, such as China and India. 
Specifically, with our tailored solutions, we are well-positioned 
to meet the increasing demand from foundries for higher-quality 
castings. This year, we expanded our customer base and further 
extended our penetration into China as sales of our pre-blended 
products increased by 17%. With the investments we are making in 
our mining, manufacturing, and technology capabilities, we anticipate 
continued growth in Asia.

INCREASE PRECIPITATED CALCIUM  
CARBONATE (PCC) VOLUMES GLOBALLY 

We are the world’s largest PCC producer with the most advanced 
portfolio of technologies, including high filler and applications for 
consumer packaging and paper waste recycling. Our objective 
is to increase PCC volumes globally through base filler contracts 
in underpenetrated regions and by capitalizing on growing 
opportunities in adjacent markets, such as packaging applications, 
where we can deploy these latest solutions. 

In 2020, our growth in China continued on a strong trajectory 
as PCC sales increased by 13%, and we commissioned three new 
satellites in China, India and the U.S., totaling over 200,000 tons 
of new capacity. Looking ahead, we are bringing online 70,000 
tons of additional PCC capacity in Asia and Europe in 2021, which 
combined with the ramp-up of our latest satellites, will help drive 
volume growth.

COMPREHENSIVE NEW PRODUCT PIPELINE 
MEETING EVOLVING CUSTOMER PREFERENCES

New product development is a key growth strategy for our 
company, and our objectives are to improve the speed of 
execution, increase the number of products commercialized,  
and enhance the impact of our latest solutions. Over the past  
five years, we have reduced the time from development to 
market in half, and at the same time, increased our sales from 
new products by more than 50%. 

Specific to 2020, we made notable progress on these objectives. 
We commercialized 44 value-added products and incorporated 
sustainability indicators to ensure we are meeting both our own 
environmental goals as well as those of our customers’. Notable 
technologies include water remediation solutions to address  
per- and polyfluoroalkyl substances (PFAS), PCC for packaging 
applications, advanced formulations for edible oil purification,  
new waterproofing applications, and our 100% carbon-neutral  
pet care product. Many of these new products are helping us 
penetrate more consumer-oriented applications and enter 
adjacencies with customers.

CAPITAL WITH A BALANCED APPROACH 

STRONG PIPELINE 
OF ACQUISITION 
OPPORTUNITIES

While operating in a more uncertain environment, we prioritized cash flow and 
creating flexibility around our capital structure. During the year, we delivered 
strong free cash flow of $175 million, which was used to reduce net debt 
by $122 million and return $48 million to our shareholders. In addition, we 
capitalized on attractive credit market conditions by completing a $400 million 
offering of senior unsecured notes, which extended our weighted average  
debt maturity by 2.5 years, and increased liquidity by nearly $250 million.

Acquisitions are a key component of our long-term growth strategy, and  
we maintain a robust pipeline of minerals-based opportunities that align 
with our strategic initiatives. In 2020, we acquired a small hauling and mining 
company which further strengthened our vertically integrated position at  
our bentonite mines in Wyoming. 

LIVING OUR VALUES AND BUILDING 
A MORE DIVERSE AND INCLUSIVE 
WORKFORCE

As we drive value for our stakeholders, how we do it is equally as important as 
what we do. At the heart of MTI are our talented employees who are integral to 
driving our high-performance culture. We are committed to fostering our talent, 
providing extensive learning and development opportunities, and attracting  
and building the workforce that will help support and grow MTI for the future.

Supported by our  
strong and flexible  
balance sheet

With our global footprint, we have seen firsthand the energy and innovation  
that come from encouraging diverse perspectives and backgrounds. Tragic 
incidents this past year brought into clear view the inequities that exist 
in society and reinforced the importance of taking deliberate actions to 
understand biases and ensure all employees feel welcomed and heard. 
Led by our Global Inclusion Council, we have been focused on raising 
awareness, educating our employees through global training on topics 
such as unconscious bias, and identifying initiatives to support  
a more diverse and inclusive environment. Together, we are making 
strides to further promote an inclusive and open culture at MTI built 
on our core values of respect, honesty, and trust.

With our strong financial 
position, we have the 
resources to execute on  
our growth initiatives and 
the flexibility to also deploy 
capital in a balanced way 
through dividends and  
share repurchases, as well  
as towards acquisitions.

ADVANCING BROAD 
SUSTAINABILITY INITIATIVES 

Sustainability is core to who we are and how we operate. It encompasses the engagement of our employees, 
continuously developing new products to address customer needs, and managing our natural resources to 
support our stakeholders and the communities where we live and operate. Over the past few years, we have 
taken meaningful steps to embed these activities deeper into our company while aligning them with our business 
strategy and financial goals. Specifically, we are on track to meet or exceed  
our 2025 environmental targets in six focus areas. We have mapped our  
sustainability strategy and framework using the Global Reporting  
Initiative (GRI) standards, which has helped us to take a more holistic  
look at our economic, environmental, and social impacts based  
on the priorities of our stakeholders. I established a dedicated  
Sustainability Lead Team in 2019 to manage progress towards  
achieving our targets, support implementation of global projects,  
and improve our external disclosures. Through the guidance  
of our Sustainability Lead Team and the involvement of all  
MTI employees, we continue to take steps to ensure the  
long-term sustainability of our company.

LOOKING AHEAD IN 2021

In 2020, the team at MTI demonstrated tremendous engagement and ingenuity, which enabled us to protect 
the health and safety of our employees, to solve customers’ challenges in new ways, and to succeed in a world 
transformed by the COVID-19 pandemic. Our market-leading positions and high-value product portfolio enabled  
us to drive growth prospects with customers no matter what we faced and set us up for further success as markets 
continue to improve. The changes we made in 2020, including our operational measures and our approach to 
doing business differently in a virtual environment, will serve as competitive advantages going forward.

Our business is diverse and resilient. Our operations are nimble. Our financial position is strong. And our team 
is engaged, focused on operating safely and efficiently, and fostering our high-performance culture. With the 
positive momentum that we generated at the end of 2020, we are well positioned to execute on the attractive 
opportunities in front of us.

On behalf of all of us at MTI, we thank you for your investment. And to the incredible MTI team — thank you for  
all you do to support our company, each other, and our customers. 

Stay safe and stay well.

People-Focused Culture Key  
to Our Success

Our Employees are at the Core of Everything We Do

Our people are the most important part of MTI. We are a dynamic global team of 3,500 plus employees and 
our core values — people, excellence, honesty, customer focus and accountability — guide our actions. In 2020, 
the world faced a global health crisis that affected nearly every person in every part of the globe. As we have done 
during other challenging times, our employees at MTI came together and forged ahead to ensure that we could 
serve our customers while protecting the health and safety of our employees. While we remained open for business, 
our employees demonstrated their resiliency, ingenuity and agility. They developed new ways to work effectively 
as we navigated the challenges of staying connected while maintaining a safe distance from each other. Our teams 
also made significant contributions to our company as well as their local communities.

Operational Excellence:

A Strategic Differentiator for MTI

OE provides MTI with a common language 
and collective mindset to address a 
problem or challenge anywhere in the 
world. Read more in our OE Brochure  
on our company’s website. 

Our Operational Excellence (OE) journey, rooted in the active engagement of our employees, began nearly 15 years  
ago when we developed a highly structured business system of lean principles. We’ve significantly advanced OE 
throughout our company, building a culture of continuous improvement where each employee is empowered to apply  
these people-focused values 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 agility by  
applying their skills in ways that deliver measurable outcomes and create both business and social value.

In 2020, we saw firsthand the power of our culture as we quickly adapted to the many challenges we faced and 
implemented new tools and processes to operate efficiently, collaborate effectively, and deliver value to our 
customers. While working under different conditions, we continued to advance our multitude of value-enhancing 
activities, development opportunities and recognition programs at a similar pace to the previous year. 

8,600 

KAIZEN EVENTS CONDUCTED 
(highly focused problem-solving workshops  
to improve product and service processes).  
Nearly 24 kaizen events occur across MTI  
on a daily basis.

63,000 

SUGGESTIONS FROM EMPLOYEES 
ON HOW TO REMOVE WASTE AND RISK  
FROM OUR PROCESSES AND PROCESSES. 

Employees shared about 173 suggestions

DEVELOPING OUR PEOPLE

We are always refining our high-performance culture by 
developing talent from within — and hiring the best people 
— through unique leadership development opportunities, 
comprehensive training programs, meaningful employee 
engagement and a global internship program. Investing in skills 
and the acceleration of employees’ professional and personal 
development are essential components of our people strategy. 

DIVERSITY AND INCLUSION

Our focus on people is advancing our diversity & inclusion 
(D&I) commitment and our efforts are aimed at continuous 
improvement in fostering a culture of diversity and inclusion  
at every level of our company. Under the guidance of the Global 
Inclusion Council and the collaboration of all MTI employees,  
we are making tangible progress. During 2020, we introduced  
a comprehensive online training module, focused on 
unconscious bias, microinequities and the importance of 
diversity and inclusion, which was completed by all MTI 
employees. We have also embedded D&I practices further 
into our performance evaluations and onboarding, succession 
planning, leadership development, and recruitment processes.

Sustainability Leadership

Making a Meaningful Difference Through 
Our Wide-Reaching Environmental,  
Social and Governance (ESG) Initiatives

Learn more about 
our ESG initiatives 
in our Corporate 
Responsibility 
and Sustainability 
Report available  
on the MTI  
website.

Sustainability has always been part of MTI’s DNA and is the foundation of how we operate. It starts with our 
people — attracting and developing a talented, diverse, engaged workforce, ensuring everyone arrives home 
safely each day, and by being a responsible neighbor in our communities. We are continuously evaluating ways  
to better protect the environment and improve our footprint, optimize our processes to conserve resources,  
and enhance the value of our innovative products.

For 12 years, MTI has published an annual Corporate Responsibility and Sustainability Report describing our efforts 
in continuous improvement regarding our safety culture, environmental performance, social impact, new product 
development, and community engagement. In the past few years, we have taken significant steps in our journey  
to further embed and align our sustainability practices with our business strategy and goals. 

OUR JOURNEY 
CONTINUES 

As we advance our current goals,  
we anticipate identifying additional  
areas toa drive our efforts further, 
including implementing new,  
broader goals. 

Established 2025 environmental targets  
in six focus areas. 

Formed a dedicated Sustainability Lead Team  
to bring more structure to our sustainability 
strategy, oversee initiatives to achieve our targets, 
and improve our external reporting and disclosures. 

Mapped our sustainability strategy and framework 
using the Global Reporting Initiative (GRI) standards 
and intend to start the process of disclosing through 
the Sustainability Accounting Standards Board 
(SASB) framework.

PROGRESS WITH OUR 2025 ENVIRONMENTAL TARGETS IN YEAR 1* 

We have made significant strides in our first year — from identifying our highest-priority activities to engaging 
employees to adopt a more energy-efficient and resource conservation mindset. We are on track to meet or  
exceed our reduction targets and have implemented several projects that will drive significant improvement  
in the years ahead.

PROJECTS TO HELP MTI MEET OR EXCEED ENVIRONMENTAL TARGETS

We have switched to natural gas processes as the energy  
source for drying bentonite clay at one of our largest 
facilities. This has helped to significantly reduce Scope 
1 Direct GHG emissions and airborne pollutants. 
We continue to implement projects to convert 
additional dryers to natural gas while also 
improving fuel usage efficiency at our sites. 

We recently signed a contract to source 50% of the electricity 
at our Colony, Wyoming location with green wind energy. 
This project should reduce MTI’s Scope 2 Indirect GHG 

emissions by about 6% in 2021. In addition, our European 
Pet Care business is carbon-neutral and has installed 
over 1,300 solar panels at its facilities. We are 
evaluating additional opportunities across 

our global operations to achieve our goal 
of sourcing 50% of electricity from 
renewable sources by 2025.

Our Lifford, UK facility has 
implemented an alternative outlet for 
their by-product precipitated calcium 
carbonate (PCC) and achieved a 70% 
reduction in process waste since 2018. 
Our Paper PCC business has developed 
a treatment process for agricultural and 
beneficial reuse applications equating to  
about 40,000 tons of PCC by-products,  
45% of our total production.

In 2020, we reduced our 
environmental releases  
by 32% through our focus  
on spill prevention, 
enhanced compliance 
tracking, and more rigor 
around identifying the  
most likely release activities.

In 2020, we extracted over 1 million tons 
of waste carbon dioxide from our PCC 
customers’ exhaust stacks as well as our 
own and sequestered those emissions in 
useful products, reducing harmful release 
to the atmosphere.

Our PCC plants consume 
and discharge a significant 

portion of our total water at MTI. 

At several of our sites, we have 
executed innovative closed-loop 
systems to recover water and waste 
in production. Some of these projects 
have led to nearly a 100% reduction in 
water discharged to municipalities and 
saved over 300 million gallons produced 

in our operations in 2020.

greenhouses on local school campuses. We also help to salvage 
and replant Joshua Trees and Mojave Yuccas using temporary 
waterlines to help the plants grow on their new site.

Many of our locations around the globe 
celebrate World Environment Day with 
a focus on creating awareness among 
employees of the importance of taking 
positive environmental steps to protect 
nature and the environment. Activities include 
planting new greenery and discussing ways to 
reduce noise and pollution in the community.

Our commitment to people extends to the communities where we work. We 
support and sponsor facility-led volunteer initiatives and donations to local 
charities, plant visits for community members, local employment opportunities 
and career fairs. Examples include our significant participation in several local 
United Way campaigns, an organization that champions the health, education 
and financial stability of individuals. In addition, we have partnered with 
Jumpstart for Young Children, an early education non-profit focused  
on improving literacy in under-resourced communities in the U.S, to provide 
books to schools in need.

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®.

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. 

PCC Products – Paper 

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

● 

● 

as a filler in the production of coated and uncoated wood-free printing and writing papers, such as office papers; 

as a filler in the production of coated and uncoated groundwood (wood-containing) paper such as magazine and catalog 
papers; and 

● 

as a coating pigment for both wood-free and groundwood papers and packaging. 

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. 

6 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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. 

PCC Markets – Paper 

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. 

Processed Minerals – Products and Markets 

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")

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 

Refractory – Products and Markets 

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: 

●  HOTCRETE®: High durability shotcrete products for applications at high temperatures in ferrous applications, such as, 

steel ladles, electric arc furnaces (EAF) and basic oxygen furnaces (BOF). 

●  FASTFIRE®:  High  durability  castable  and  shotcrete  products  in  the  non-ferrous  and  ferrous  industries  with  the  added 

benefit of rapid dry-out capabilities.

Ladle. The torpedo ladles transport liquid iron from a blast furnace to the steel plant. 

●  LACAM® LI Explorer: A laser scanning system that measures the refractory lining thickness from the interior of a Hot 
Steel  Ladle.    By  entering  the  interior,  the  explorer  provides  the  ability  to  see  all  areas  of  the  ladle  and  identify  the 
smallest flaws in the refractory lining. 

●  LACAM®: A new, fourth generation Lacam® laser measurement device for use in the worldwide steel industry that is 17 
times faster than the previous version. This new technology provides the fastest and most accurate laser scanning for hot 
surfaces available today.

Marketing and Sales 

The Company relies principally on its worldwide direct sales force to market its products. The direct sales force is augmented 
by technical service teams that are familiar with the industries to which the Company markets its products, and by several regional 
distributors. The Company's sales force works closely with the Company's technical service staff to solve technical and other issues 
faced by the Company's customers. 

In  the  Performance  Materials  segment,  the  Company  relies  on  industry-specialized  technically  oriented  salespersons.    In 
Metalcasting,  these  sales  teams  provide  expertise  to  educate  our  customers  on  the  bentonite  blend  properties  and  to  aid  them  in 
producing  castings  efficiently.  Certain  other  products  are  distributed  through  networks  of  distributors  and  representatives,  who 
warehouse  specific  products  at  strategic  locations.  In  addition,  the  sales  and  distribution  of  environmental  products  and  building 
materials  are  primarily  performed  through  the  Company’s  own  personnel  and  facilities.  Our  staff  includes  sales  professionals  and 
technical  support  engineers  who  analyze  the  suitability  of  our  products  in  relation  to  the  customer’s  specific  application  and  the 
conditions that products will endure or the environment in which they will operate. 

In the Specialty Minerals segment, the Company's sales team and technical services staff assist paper producers in ongoing 
evaluations  of  the  use  of  PCC  for  paper  coating  and  filling  applications  as  well  as  PCC,  GCC  and  talc  use  in  the  automotive, 
construction and household goods markets. 

In  the  Refractories  segment,  the  Company's  technical  service  personnel  advise  on  the  use  of  refractory  materials,  and,  in 

many cases pursuant to service agreements, apply the refractory materials to the customers' furnaces and other vessels. 

In the Energy Services segment, the Company’s sales team sell the services on a direct basis. 

Continued  use  of  skilled  technical  service  teams  is  an  important  component  of  the  Company's  business  strategy.  The 
Company works closely with its customers to ensure that  their  requirements are satisfied,  and it  often trains  and  supports  customer 
personnel  in  the  use  of  the  Company's  products.  The  Company  oversees  domestic  marketing  and  sales  activities  principally  from 
Bethlehem, Pennsylvania and Hoffman Estates, Illinois, and from regional sales offices located elsewhere in the United States. The 
Company's international marketing and sales efforts are directed from regional centers located in India, the United Kingdom, Brazil, 
and  China.  The  Company  believes  that  its  worldwide  network  of  sales  personnel  and  manufacturing  sites  facilitates  continued 
international expansion. 

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. 

11 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 RESISTEXTM 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.

We  provide  an  array  of  programs  to  recognize  individual  and  team  achievements,  and  to  enable  us  to  appropriately  reward 
performance  consistent  with  employee  contributions.  MTI  has  a  strong  commitment  to  pay  for  performance  at  all  levels.  This 
commitment  is  embodied  through  merit  increases,  incentive  compensation  and  our  variable  pay  plans.  We  offer  competitive 
compensation to attract and retain the best people.  Our benefits are designed to help employees and their families stay healthy, meet 
their  financial  goals,  protect  their  income  and  help  them  balance  their  work  and  personal  lives.  These  benefits  include  health  and 
wellness,  paid  time  off,  employee  assistance,  competitive  pay,  tuition  reimbursement,  career  growth  opportunities,  and  a  culture of 
recognition.  

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. 

COVID-19 Pandemic Risk 

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 
15 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 have experienced, and may experience in the future, temporary facility closures in response to government mandates 
in certain jurisdictions in which we operate.  We may also be required to close certain of our facilities for the safety of 
our  employees  in  response  to  positive  diagnoses  for  COVID-19.    Even  in  facilities  that  are  not  closed,  we  could  be 
affected by reductions in employee availability and effectiveness, changes in operating procedures, and increased costs. 
●  Our  customers  have  been,  and  may  continue  to  be,  affected  by  COVID-19  and  the  business  slowdown  caused  by 
preventative measures, resulting in decreased demand for our products and services, delayed payments from customers 
and uncollectable accounts. 

●  Our  supply  chain  could  be  disrupted.    This  could  materially  adversely  impact  our  ability  to  secure  raw  materials  and 

supplies for our facilities, which could materially adversely affect our operations. 

●  Significant  disruption  of  global  financial  markets  could  have  a  negative  impact  on  our  ability  to  access  capital  in  the 

future. 

●  Further  or  prolonged  impact  from  COVID-19  could  result  in  impairment  of  asset  charges,  including  long-lived  or 

intangible assets, inventory or bad debt charges. 

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. 

Industry and Market Risks 

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. 

16 

 
 
 
 
 
 
 
 
 
 
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 

17 

 
 
 
 
 
 
 
 
 
 
 
 
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. 

Financial Risks 

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. 

Technology, Development and Growth Risks 

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 

18 

 
 
 
 
 
 
 
 
 
 
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 
19 

 
 
 
 
 
 
 
 
 
 
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. 

Operational Risks 

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. 

20 

 
 
 
 
 
 
 
 
 
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 Energy Services Segment and certain product lines within our Performance Materials segment are affected by seasonal 
weather patterns. A majority of our Energy Services revenues are derived from the Gulf of Mexico and surrounding states, which are 
susceptible  to  hurricanes  that  typically  occur  June  1st  through  November  30th.  Actual  or  threatened  hurricanes  can  result  in  volatile 
demand  for  services  provided  by  our  Energy  Services  segment.  Our  Environmental  Products  and  Building  Materials  product  lines 
within our Performance Materials segment are affected by weather patterns which determine the feasibility of construction activities. 
Typically, less construction activity occurs in winter months and thus this segment’s revenues tend to be greatest in the second and 
third quarters when weather patterns in our geographic markets are more conducive to construction activities. Our Processed Minerals 
product line is subject to similar seasonal patterns. 

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.

*  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.

*   During the fourth quarter of 2017, the Company recorded a provisional $47 million income tax benefit from the U.S. Tax Cuts 
and Job Acts legislation.  This benefit is comprised of an $82 million benefit which related primarily to the remeasurement of the 
Company’s  U.S.  deferred  tax  liabilities  at  a  lower  U.S.  tax  rate  of  21%,  partially  offset  by  tax  expense  of  $35  million  for  the 
deemed repatriation of unremitted earnings of foreign subsidiaries.  During 2018, the Company recorded a benefit of $4.4 million 
as a measurement period adjustment to the deemed repatriation of unremitted earnings of foreign subsidiaries.

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:

tax rates were 17.7%, 14.5% and 16.9% during 2020, 2019 and 2018, respectively.  Included in the provision for taxes for 2018 is a 
$4.4 million benefit representing an adjustment of the provisional amounts previously recorded for the U.S. Tax Cuts and Jobs Act 
(“U.S. Tax Reform”) legislation, enacted in December 2017.   

The higher effective tax rate in 2020 as compared to 2019 was primarily due to tax credits in the prior year resulting from the 
expiration  of  a  tax  statute  of  limitations.    The  lower  effective  tax  rate  in  2019  as  compared  to  2018  was  primarily  due  to 
aforementioned tax benefits resulting from the expiration of a tax statute of limitations.  

The  other  factors  having  the  most  significant  impact  on  our  effective  tax  rates  in  recent  periods  are  the  rate  differentials 
related to foreign earnings indefinitely invested, percentage depletion, and the tax benefits on restructuring and impairment charges at 
a higher rate.   

Percentage  depletion  allowances  (tax  deductions  for  depletion  that  may  exceed  our  tax  basis  in  our  mineral  reserves)  are 
available to us under the income tax laws of the United States for operations conducted in the United States.  The tax benefits from 
percentage depletion were $8.5 million in 2020, $7.8 million in 2019 and $8.0 million in 2018. 

The U.S. Tax Reform legislation established a  new Global  Intangible Low-Tax Income provision (“GILTI”) that  currently 
taxes certain income from foreign operations.  The Company has elected, as its accounting policy, to treat the taxes due from GILTI as 
a current period expense when incurred. The net charge to the Company for GILTI was $0.6 million and $2.1 million for 2020 and 
2018, respectively.  There was no charge for GILTI in 2019. 

We  operate  in  various  countries  around  the  world  that  have  tax  laws,  tax  incentives  and  tax  rates  that  are  significantly 
different than those of the United States.  These differences combine to move our overall effective tax rate higher or lower than the 
United States statutory rate depending on the mix of income relative  to  income earned  in the  United  States.   The  effects  of foreign 
earnings and the related foreign rate differentials resulted in increases of $4.6 million, $6.0 million and $2.3 million in 2020, 2019 and 
2018, respectively. 

Consolidated Net Income Attributable to MTI Shareholders 

Consolidated net income was $115.8 million in 2020 and included a $24.1 million charge, net of tax.  This charge consisted 
of  litigation  expenses  associated  with  the  bankruptcy  of  Novinda  Corp.,  asset  write-downs,  severance-related  costs,  IT  incident 
remediation cost, acquisition-related costs and a non-cash pension settlement charge.   

Consolidated net income was $136.4 million in 2019 and included a $20.8 million charge, net of tax.  This charge consisted 

of the asset write-downs, severance-related costs and litigation expenses associated with the bankruptcy of Novinda Corp.

Net sales in the Performance Materials segment in 2020 were $752.8 million and decreased $70.5 million, or 9 percent from 
2019.  Metalcasting’s  sales  decreased  $33.1  million  or  11  percent,  primarily  due  to  COVID-19  related  weaker  foundry  demand  in 
North  America.  Household,  Personal  Care  &  Specialty  Products  sales  increased  $3.6  million  or  1  percent  from  the  prior  year, 
primarily driven by strong demand for consumer-oriented products. Environmental Products and Building Materials sales experienced 
COVID-19 related project delays that yielded a decrease in sales from the prior year of $28.0 million and $13.0 million, respectively. 

Income from operations increased $6.5 million to $103.6 million in 2020 and represented 13.8% of net sales as compared to 
$97.1 million and 11.8% of sales in 2019.  Pricing actions, cost control and expense reductions more than offset the impact of lower 
sales versus the prior year. 

2019 v 2018 

Net sales in the Performance Materials segment in 2019 were $823.3 million and decreased $4.8 million, or 1 percent from 
2018.  Foreign  exchange  had  an  unfavorable  impact  of  $13.4  million  or  2%.    Metalcasting’s  sales  decreased  $37.7  million  or  11 
percent, primarily due to lower market-based pricing and volumes in the specialty sands products, as well as weaker demand in US 
automotive,  heavy  truck  and  agriculture  equipment.    Household,  Personal  Care  &  Specialty  Products  sales  increased  8  percent, 
primarily  driven  by  continued  strong  performance  of  our Global  pet  care  business,  as  well  as  increases  in  our  Human  and  Animal 
Health businesses.  In the third quarter of 2019, the Company combined its Basic Minerals product line with its Household, Personal 
Care & Specialty Products product line.  Environmental Products sales rose 8 percent due to a large international project and higher 
volumes of our geosynthetic clay liners and specialty liners.   Building Materials sales decreased 2% due primarily to the difference in 
magnitude of waterproofing projects as compared with prior year. 

Income from operations decreased $19.7 million to $97.1 million in 2019 and represented 11.8% of net sales as compared to 

$116.8 million and 14.1% of sales in 2018.   Included in income from operations were $7.0 million of restructuring and impairment 
costs.  While pricing actions more than offset higher raw material costs, operating income and margins were impacted by lower 
Metalcasting sales and unfavorable product mix.

Net  sales  in  the  Specialty  Minerals  segment decreased  11  percent  to  $510.9 million  in  2020  from $574.4  million  in  2019. 
Worldwide sales of PCC products decreased to $377.7 million in 2020 from $434.0 million in the prior year largely due to lower paper 
demand and temporary COVID-19 related customer shutdowns.    Specialty  PCC sales  remained flat as compared  with  prior year  as 
automotive and residential construction markets rebounded during 2020 and consumer-oriented markets continue to be strong.  Sales 
of  Processed  Minerals  products  decreased  5  percent  to  $133.2  million  in  2020  primarily  driven  by  the  slowdown  in  residential 
construction and automotive markets in the second and third quarters.  

Income from operations decreased $15.3 million to $67.8 million  in 2020 and represented  13.3% of  net sales compared  to 
$83.1  million  and  14.5%  of  sales  in  the  prior  year.  Included  in  income  from  operations  were  $7.6  million  of  restructuring  and 
impairment costs.     

2019 v 2018 

Net  sales  in  the  Specialty  Minerals  segment  decreased  3  percent  to  $574.4  million  in  2019  from  $589.3  million  in  2018. 
Worldwide sales of PCC products decreased to $434.0 million in 2019 from $445.4 million in the prior year largely due to previously 
announced customer paper machine shutdowns in North America, including the closure of two U.S. paper mills in the first and fourth 
quarters of 2019.  These shutdowns were offset by a 3 percent increase in Paper PCC volumes in Asia as a result of the ramp up of a 
new  satellite  and  additional  capacity.    Specialty  PCC  increased  3  percent  primarily  due  to  demand-driven  expansions.    Sales  of 
Processed Minerals products decreased 2 percent to $140.4 million in 2019 primarily driven by a reduction of sales in the automotive 
and construction markets.  

Income from operations decreased $12.3 million to $83.1 million  in 2019 and represented  14.5% of  net sales compared  to 
$95.4 million and 16.2% of sales in the prior year.  This decrease was primarily driven by the paper mill shutdowns in North America 
and  lower  volumes  in  Europe,  which  was  partially  offset  by  higher  pricing.    Included  in  income  from  operations  for  2019  were 
restructuring and asset write-down charges of $2.5 million.

Net sales in the Refractories segment decreased 13 percent to $258.1 million in 2020, as a result of steel mill utilization rates 
decline in the second quarter in North America and Europe, which was followed by a gradual improvement in the second half of the 
year.  

Income  from  operations  decreased  $4.3  million  to  $35.5  million  and  represented  13.8%  of  net  sales  in  2020  compared  to 

$39.8 million or 13.4% of sales in 2019 due to lower refractory volumes globally.   

2019 v 2018 

Net  sales  in  the  Refractories  segment  decreased  4  percent  to  $298.1  million  in  2019,  driven  by  lower  sales  of  Refractory 

products globally, partially offset by higher metallurgical products and laser equipment sales.  

Income from operations decreased $5.6 million to $39.8 million and represented 13.4% of net sales in 2019 compared to 

$45.4 million or 14.6% of sales in 2018 due to lower refractory volumes globally.  Included in income from operations for 2019 were 
restructuring and asset write-down charges of $0.8 million and a $2.5 million bad debt reserve relating to a customer bankruptcy.

Net sales in the Energy Services segment decreased $22.2 million in 2020 or 23 percent, primarily driven by the decrease in 

activity due to COVID-19 restrictions and the impact of storm activity in the Gulf of Mexico.  

The segment recorded income from operations of $5.2 million in 2020 as compared to $7.8 million in the prior year.   

2019 v 2018 

Net sales in the Energy Services segment increased $16.9 million in 2019 or 22 percent, driven by higher well testing and 
filtration activity in the North Sea and Gulf of Mexico and increased equipment sales and filtration activity in the Asia Pacific region.  

The  segment  recorded  income  from  operations  of  $7.8  million  in  2019  as  compared  to  $4.5  million  in  the  prior  year.  

Included in income from operations was $1.8 million of restructuring and asset write-down charges in 2019.

Liquidity and Capital Resources 

Cash  provided  from  continuing  operations  in  2020  was  $240.6  million,  compared  with  $238.3  million  in  prior  year.  Cash 
flows  provided  from  operations  in  2020  were  principally  used  to  repay  debt,  fund  capital  expenditures,  acquire  assets,  repurchase 
shares  and  to  pay  the  Company's  dividend  to  common  shareholders.  The  Company’s  intention  is  to  use  excess  cash  flow  for 
investments in growth, continued debt reduction and selective share repurchases.  

On  May  9,  2014,  in  connection  with  the  acquisition  of  AMCOL  International  Corporation  (“AMCOL”),  the  Company 
entered  into  a  credit  agreement  providing  for  the  $1.560  billion  senior  secured  term  loan  facility  (the  “Term  Facility”)  and  a  $200 
million senior secured revolving credit facility (the “Revolving Facility” and, together with the Term Facility, the “Facilities”).  

On June 23, 2015, the Company entered into an amendment (the “First Amendment”) to the credit agreement to reprice the 
$1.378 billion then outstanding on the Term Facility. As amended, the Term Facility had a $1.078 billion floating rate tranche and a 
$300 million fixed rate tranche. On February 14, 2017, the Company entered into an amendment (the “Second Amendment”) to the 
credit  agreement  to  reprice  the  $788  million  floating  rate  tranche  then  outstanding,  which  extended  the  maturity  and  lowered  the 
interest costs by 75 basis points. On April 18, 2018, the Company entered into an amendment (the “Third Amendment”) to the credit 
agreement to refinance its then existing senior secured revolving credit facility.  In connection with the Third Amendment, the existing 
senior secured revolving credit facility was replaced with a new revolving credit facility with $300 million of aggregate commitments 
(the  “Revolving  Credit  Facility”  and,  together  with  the  Term  Facility,  the  “Senior  Secured  Credit  Facilities”).  Following  the 
amendments, the loans outstanding under the floating rate tranche of the Term Facility are scheduled to mature on February 14, 2024, 
the loans outstanding (if any) and commitments under the Revolving Facility will mature and terminate, as the case may be, on April 
18,  2023.  Loans  under  the  fixed  rate  tranche  of  the  Term  Facility  were  repaid  in  full  in  June  2020.  Loans  under  the  floating  rate 
tranche of the Term Facility bear interest at a rate equal to an adjusted LIBOR rate (subject to a floor of 0.75%) plus an applicable 
margin equal to 2.25% per annum.  Loans under the Revolving Facility bear interest at a rate equal to an adjusted LIBOR rate plus an 
applicable margin equal to 1.625% per annum. Such rates are subject to decrease by up to 25 basis points in the event that, and for so 
long as, the Company’s net leverage ratio (as defined in the credit agreement) is less than certain thresholds. The variable rate tranche 
has a 1% required amortization per year. The Company will pay certain fees under the credit agreement, including customary annual 
administration fees. The obligations of the Company under the Senior Secured Credit Facilities are unconditionally guaranteed jointly 
and  severally  by,  subject  to  certain  exceptions,  all  material  domestic  subsidiaries  of  the  Company  (the  “Guarantors”)  and  secured, 
subject to certain exceptions, by a security interest in substantially all of the assets of the Company and the Guarantors. 

On  June  30,  2020,  the  Company  issued  $400  million  aggregate  principal  amount  of  5.0%  Senior  Notes  due  2028  (the 
“Notes”).  The Notes were issued pursuant to an indenture, dated as of June 30, 2020, between the Company and The Bank of New 
York Mellon Trust Company, N.A.,  as trustee.   The Company used  the  net proceeds  of its  offering  of  the Notes to  repay all of  its 
outstanding loans under the fixed rate tranche of the Term Facility, repay all of its outstanding borrowings under its Revolving Credit 
Facility, and the remainder for general corporate purposes. 

The Notes bear an interest rate of 5.0% per annum payable semi-annually on January 1 and July 1 of each year, beginning on 
January 1, 2021.  The Notes are unconditionally guaranteed on a senior unsecured basis by each of the Company’s existing and future 
wholly owned domestic restricted subsidiaries that is a borrower under or that guarantees the Company’s obligations under its Senior 
Secured Credit Facilities or that guarantees the Company’s or any of the Company’s wholly owned domestic subsidiaries’ long-term 
indebtedness in an aggregate amount in excess of $50 million. 

At any time and from time  to time  prior to July 1, 2023,  the Company may  redeem some or all of the Notes for cash at a 
redemption price equal to 100% of their principal amount, plus the “make-whole” premium described  in the Indenture and accrued 
and unpaid interest, if any, to, but excluding, the applicable redemption date. Beginning on July 1, 2023, the Company may redeem 
some or all of the Notes at any time and from time to time at the applicable redemption prices listed in the Indenture, plus accrued and 
unpaid interest, if any, to, but excluding, the applicable redemption date. In addition, at any time and from time to time prior to July 1, 
2023,  the  Company  may  redeem  up  to  40%  of  the  aggregate  principal  amount  of  the  Notes  with  funds  from  one  or  more  equity 
offerings at a redemption price equal to 105.000%  of  the principal  amount thereof,  plus accrued  and unpaid interest, if any, to,  but 
excluding, the applicable redemption date. 

If the Company experiences a change of control (as defined in the indenture), the Company is required to offer to repurchase 
the  Notes  at  101%  of  the  principal  amount  of  such  Notes,  plus  accrued  and  unpaid  interest,  if  any,  to,  but  excluding,  the  date  of 
repurchase.

The  credit  agreement  and  the  Notes  contain  certain  customary  affirmative  and  negative  covenants  that  limit  or  restrict  the 
ability of the Company and its restricted subsidiaries to enter into certain transactions or take certain actions. In addition, the credit 
agreement contains a financial covenant that requires the Company, if on the last day of any fiscal quarter loans or letters of credit 
were outstanding under the Revolving Facility (excluding up to $25 million of letters of credit), to maintain a maximum net leverage 
ratio (as defined in the credit agreement) of 3.50 to 1.00 for the four fiscal quarter periods preceding such day. As of December 31, 
2020, there were no loans outstanding and $9.5 million in letters of credit outstanding under the Revolving Facility.  The Company is 
in compliance with all the covenants associated with the Revolving Facility as of the end of the period covered by this report. 

The  Company  has  a  committed  loan  facility  in  Japan.  As  of  December  31,  2020,  there  is  an  outstanding  balance  of  $4.1 
million on this facility.  Principal will be repaid in accordance with the payment schedules ending in 2021.  The Company repaid $0.6 
million on these loans in 2020.   

As part of the Sivomatic acquisition, the Company assumed $10.7 million in long-term debt, recorded at fair value, consisting 
of two term loans, one of which matured in the third quarter of 2020 and the other of which matures in 2022.  These loans carry an 
interest rate of Euribor plus 2.0% and have quarterly repayments.  During 2020, the Company repaid $1.5 million on these loans. 

As of December 31, 2020, the Company had $25.6 million in uncommitted short-term bank credit lines, none of which were 
in use. The credit lines are primarily outside the U.S. and are generally one year in term at competitive market rates at large, well-
established institutions.  The Company typically  uses  its  available credit lines  to fund working capital  requirements or local capital 
spending needs.  We anticipate that capital expenditures for 2021 should be between $75 million and $85 million, principally related 
to opportunities to improve our operations and meet our strategic growth objectives. We expect to meet our other long-term financing 
requirements from internally generated funds, committed and uncommitted bank credit lines and, where appropriate, project financing 
of certain satellite plants. 

On April 5, 2016, the Company entered into a floating to fixed interest rate swap for an initial aggregate notional amount of 
$300 million to limit exposure to interest rate increases related to a portion of the Company’s floating rate indebtedness.  This swap 
agreement hedges a portion of contractual floating rate interest through its expiration in May 2021.  As a result of the agreement, the 
Company’s  effective  fixed  interest  rate  on  the  notional  amount  floating  rate  indebtedness  will  be  4.25%.  The  fair  value  of  this 
instrument at December 31, 2020 was a liability of less than $0.1 million. 

During the second quarter of 2018, the Company entered into a floating to fixed interest rate swap for a notional amount of 
$150 million.  The fair value of this instrument at December 31, 2020 is a liability of $7.7 million. Additionally, the Company entered 
into a cross currency rate swap with a total notional value of $150 million to exchange monthly fixed-rate interest rate payments in 
U.S. dollars for monthly fixed-rate interest rate payments in Euros.  The fair value of this instrument at December 31, 2020 is an asset 
of  $0.4  million.  These  swaps  mature  in  May  2023.    As  a  result  of  these  swaps,  the  Company's  effective  fixed  interest  rate  on  the 
notional floating rate indebtedness will be 2.5%.  

On  October  23,  2019,  the  Company's  Board  of  Directors  authorized  the  Company's  management  to  repurchase,  at  its 
discretion, up to $75 million of the Company's shares over a one-year period.  Over this program's one-year period, 984,202 shares 
were repurchased for $49.6 million, or an average price of approximately $50.36 per share.  This program is now completed.   

On  October  21,  2020,  the  Company's  Board  of  Directors  authorized  the  Company's  management  to  repurchase,  at  its 
discretion, up to $75 million of the Company's shares over a one-year period.  As of December 31, 2020, 179,810 shares have been 
repurchased under this program for $11.1 million, or an average price of approximately $61.63 per share. 

On January 27, 2021, the Company's Board of Directors declared a regular quarterly dividend on its common stock of $0.05 

per share.  No dividend will be payable unless declared by the Board and unless funds are legally available for payment thereof.

Debt  amounts  in  the  preceding  table  represent  the  principal  amounts  of  all  outstanding  long-term  debt,  including  current 
portion.    As  of  December  31,  2020,  maturities  for  long-term  debt  extended  to  2028.  The  above  table  does  not  include  borrowings 
under our Revolving Facility as such amounts can be borrowed and repaid as required.  Any remaining outstanding loans under the 
Revolving Facility will mature in April 2023.  

Interest related to long-term debt is based on interest rates in effect as of December 31, 2020 and is calculated on debt with 
maturities that, on December 31, 2020 extended to 2024. As the contractual interest rate for a portion of our debt is variable, actual 
cash payments may differ from the estimates provided in the preceding table. 

Estimated  minimum  required  pension  funding  and  post-retirement  benefits  are  based  on  actuarial  estimates  using  current 
assumptions for discount rates, long-term rate of return on plan assets, rate of compensation increases, and health care cost trend rates. 
The Company has determined that it is not practicable to present expected pension funding and other postretirement benefit payments 
beyond 2022 and, accordingly, no amounts have been included in the table beyond such dates. 

The  Company  has  several  non-cancelable  operating  leases,  primarily  for  office  space  and  equipment.  Operating  lease 

obligations includes future minimum rental commitments under non-cancelable leases. 

The Company recorded a tax liability for the one-time transition tax on accumulated foreign subsidiary earnings under U.S. 
Tax  Reform  of  $35.1  million,  payable  in  eight  annual  interest-free  installments  beginning  in  2018.  The  Company  paid  its  first 
installment in 2018 and was required to apply certain  overpayments  to the  outstanding liability.   The remaining  liability is payable 
through 2025. 

Other long-term liabilities include asset retirement obligations relating to the retirement of certain tangible long-lived assets 
and  land  restoration  obligations  at  the  Company's  PCC  satellite  facilities  and  mining  operations.    See  Note  21  to  the  Consolidated 
Financial Statements. 

The  total  amount  of  contingent  obligations  associated  with  gross  unrecognized  tax  benefits  for  uncertain  tax  positions, 
including positions impacting only the timing of tax benefits was $7.6 million at December 31, 2020.  Payment of these obligations 
would result from settlements with taxing authorities.  Due to the difficulty in determining the timing of settlements, these obligations 
are not included in the table above.  We do not expect to make a tax payment related to these obligations within the next year that 
would significantly impact liquidity. 

Critical Accounting Policies and Estimates 

Our  discussion  and  analysis  of  our financial  condition  and  results  of  operations  are  based  upon  our  consolidated  financial 
statements,  which  have  been  prepared  in  accordance  with  U.S.  generally  accepted  accounting  principles.    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 contingent assets and liabilities. 

On an ongoing basis, we evaluate our estimates and assumptions, including those related to revenue recognition, valuation of 
long-lived assets, goodwill and other intangible assets, income taxes, including valuation allowances and pension plan assumptions. 
We base our estimates on historical experience and on other assumptions that we believe to be reasonable under the circumstances, the 
results  of  which  form  the  basis  for  making  judgments  about  the  carrying  values  of  assets  and  liabilities  that  cannot  readily  be 
determined from other sources.  There can be no assurance that actual results will not differ from those estimates.

We believe the following critical accounting policies require us to make significant judgments and estimates in the 

preparation of our consolidated financial statements. 

Revenue Recognition 

Revenue is recognized at the point in time when the customer obtains control of the promised goods or services in an amount 
that reflects the consideration we expect to receive in exchange for those goods or services.  The Company's revenues are primarily 
derived from the sale of products.  Our primary performance obligation is satisfied upon shipment or delivery to our customer based 
on written sales terms, which is also when control is transferred.  Revenues from sales of equipment are recorded upon completion of 
installation and transfer of control to the customer.  Revenues from services are recorded when the services are performed. 

In most of our PCC contracts, the price per ton is based upon the total number of tons sold to the customer during the year. 
Under those contracts, the price billed to the customer for shipments during the year is based on periodic estimates of the total annual 
volume that will be sold to the customer. Revenues are adjusted at the end of each year to reflect the actual volume sold. There were 
no  significant  revenue  adjustments  in  the  fourth  quarter  of  2020  and  2019,  respectively.  We  have  consignment  arrangements  with 
certain  customers  in  our  Refractories  segment.    Revenues  for  these  transactions  are  recorded  when  the  consigned  products  are 
consumed by the customer. 

Revenues  within  our  Energy  Services  segment  is  service  based.    Certain  contracts  within  this  segment  are  long-term 
contracts.  Revenue where our performance obligations are satisfied in phases is recognized over time using certain input measures 
based on the measurement of the value transferred to the customer, including milestones achieved. 

Valuation of Long-lived Assets, Goodwill and Other Intangible Assets 

We assess the possible impairment of long-lived assets and identifiable amortizable intangibles whenever events or changes 

in circumstances indicate that the carrying value may not be recoverable. 

Goodwill  is  evaluated  for  impairment  at  least  annually.    Factors  we  consider  important  that  could  trigger  an  impairment 

review include the following: 

●   Significant under-performance relative to historical or projected future operating results; 
●   Significant changes in the manner of use of the acquired assets or the strategy for the overall business; 
●   Significant negative industry or economic trends; 
●   Market capitalization below invested capital. 

Annually, the Company performs a qualitative assessment for each of its reporting units to determine if the two-step process 
for impairment testing is required.  If the Company determines that it is more likely than not that the fair value of a reporting unit is 
less than its carrying amount, the Company then evaluates the recoverability of goodwill using a two-step impairment test approach at 
the  reporting  unit  level.    Step  one  involves  a)  developing  the  fair  value  of  total  invested  capital  of  each  reporting  unit  in  which 
goodwill  is  assigned;  and  b)  comparing  the  fair  value  of  total  invested  capital  for  each  reporting  unit  to  its  carrying  amount,  to 
determine if there is goodwill impairment.  Should the carrying amount for a reporting unit exceed its fair value, then the step one test 
is failed, and the magnitude of any goodwill impairment is determined under step two.  The amount of impairment loss is determined 
in step two by comparing the implied fair value of reporting unit goodwill with the carrying amount of goodwill. 

The Company has five reporting units; Performance Materials, PCC, Processed Minerals, Refractories and Energy Services. 
We  identify  our  reporting  units  by  assessing  whether  the  components  of  our  operating  segments  constitute  businesses  for  which 
discrete financial information is available and management regularly reviews the operating results of those components.  In the fourth 
quarter of 2020, the Company performed a qualitative assessment of each of its reporting units and determined it was not more likely 
than not that the fair value of any of its reporting units was less than their carrying values. 

Property, plant and equipment are depreciated over their useful lives. Useful lives are based on management’s estimates of 
the  period  that  the  assets  can  generate  revenue,  which  does  not  necessarily  coincide  with  the  remaining  term  of  a  customer’s 
contractual  obligation  to  purchase  products  made  using  those  assets.    Our  sales  of  PCC  are  predominately  pursuant  to  long-term 
evergreen contracts, initially ten years in length,  with  paper mills at which  we  operate satellite  PCC  plants.  The terms of  many of 
these agreements have been extended, often in connection with an expansion of the satellite PCC plant.  Failure of a PCC customer to 
renew an agreement or continue to purchase PCC from our facility could result in an impairment of assets or accelerated depreciation 
at such facility. 

43 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We  evaluate  the  recoverability  of our property,  plant  and equipment  whenever  events  or  change  in  circumstances  indicate 
that the carrying value of the assets may not  be recoverable.   For  testing the  recoverability,  we primarily use  discounted cash  flow 
models  or  cost  approach  to  estimate  the  fair  value  of  these  assets.    Critical  assumptions  used  in  conducting  these  tests  included 
expectations of our business performance and financial results, useful lives of assets, discount rates and comparable market data. 

When we acquire a company, we determine fair value on the acquisition date of assets acquired and liabilities assumed.  We 
use the income, market or cost approach (or a combination thereof) for the valuation and use valuation inputs and analyses that are 
based on market participant assumptions.  Goodwill is calculated as the excess of the consideration transferred over the assets acquired 
and represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and 
separately recognized. 

Income Taxes 

As  part  of  the process  of preparing  our  consolidated financial  statements,  we  are  required  to  estimate  our  income  taxes  in 
each of the jurisdictions in which we operate.  This process involves estimating current tax expense together with assessing temporary 
differences  resulting  from  differing  treatments  of  items  for  tax  and  accounting  purposes.    These  differences  result  in  deferred  tax 
assets and liabilities, which are included in the consolidated balance sheet.  We must then assess the likelihood that our deferred tax 
assets  will  be  recovered  from  future  taxable  income,  and  to  the  extent  we  believe  that  recovery  is  not  likely,  we  must  establish  a 
valuation  allowance.    To  the  extent  we  establish  a  valuation  allowance  or  change  this  allowance  in  a  period,  we  must  include  an 
expense within the tax provision in the Consolidated Statements of Income. 

Deferred  tax  liabilities  represent  the  amount  of  income  taxes  payable  in  future  periods.    Such  liabilities  arise  because  of 
temporary  differences  between  the  financial  reporting  and  tax  bases  of  assets  and  liabilities.    Deferred  income  tax  assets  represent 
amounts  available  to  reduce  income  taxes  payable  on  taxable  income  in  future  years.    Such  assets  arise  because  of  temporary 
differences between the financial reporting and tax bases of assets and liabilities, as well as from net operating losses.  We evaluate the 
recoverability of these future tax deductions by assessing the adequacy of future expected taxable income from all sources, including 
reversal  of  taxable  temporary  differences  and  forecasted  operating  earnings.    These  sources  of  income  inherently  rely  heavily  on 
estimates. We use our historical experience and business forecasts to provide insight.  The amount recorded for the net deferred tax 
liability was $138.4 million and $157.6 million at December 31, 2020 and 2019, respectively. 

U.S. Tax Reform was enacted on December 22, 2017 and introduces significant changes to U.S. income tax law.  Effective in 
2018, the legislation reduced the U.S. statutory tax rate from 35% to 21%, created new taxes on certain foreign-sourced earnings and 
certain related-party payments.  In addition, in 2017, the Company  was  subject  to a  one-time transition  tax  on accumulated foreign 
subsidiary  earnings  not  previously  subject  to  U.S.  income  tax.    Accounting  for  the  income  tax  effects  of  this  legislation  requires 
significant judgments and estimates in the interpretation and calculations of its provisions. 

Due  to  the  timing  of  the  enactment  and  the  complexity  involved  in  applying  the  provisions  of  the  U.S.  Tax  Reform,  the 
Company made reasonable estimates of the effects and recorded provisional amounts in our consolidated financial statements for the 
year ended December 31, 2017.  In 2018, the Company reviewed additional guidance issued by the U.S. Treasury Department, IRS 
and other standard-setting bodies, collected and prepared the necessary data, and made adjustments to the provisional amount, which 
resulted in a $4.4 million benefit recorded for the year ended December 31, 2018.  

The  application  of  income  tax  law  is  inherently  complex.  Laws  and  regulations  in  this  area  are  voluminous  and  are  often 
ambiguous.  As  such,  we  are  required  to  make  many  subjective  assumptions  and  judgments  regarding  our  income  tax  exposures. 
Interpretations  of  and  guidance  surrounding  income  tax  laws  and regulations  change  over  time.  As  such,  changes  in our  subjective 
assumptions and judgments can materially affect amounts recognized in the consolidated balance sheets and statements of operations. 
See Note 9 to the Consolidated Financial Statements for additional detail on our uncertain tax positions. 

Pension Benefits 

We  sponsor  pension  and  other  retirement  plans  in  various  forms  covering  the  majority  of  employees  who  meet  eligibility 
requirements.  Several statistical and actuarial models which attempt to estimate future events are used in calculating the expense and 
liability related to the plans.  These models include assumptions  about the discount rate, expected  return  on  plan assets and rate of 
future compensation increases as determined by us, within certain guidelines.  Our assumptions reflect our historical experience and 
management's best judgment regarding future expectations.  In addition, our actuarial consultants also use subjective factors such as 
withdrawal and mortality rates to estimate these assumptions.  The actuarial assumptions used by us may differ materially from actual 
results  due  to  changing  market  and  economic  conditions,  higher  or  lower  withdrawal  rates  or  longer  or  shorter  life  spans  of 
participants, among other things.   

44 

 
 
 
 
 
 
 
 
 
 
 
 
The investment strategy for pension plan assets is to maintain a broadly diversified portfolio designed to both preserve and 

grow plan assets to meet future plan obligations. The Company's average rate of return on assets from inception through December 31, 
2020 was approximately 9%.  The Company’s assets are strategically allocated among equity, debt and other investments to achieve a 
diversification level that dampens fluctuations in investment returns.  The Company’s long-term investment strategy is an investment 
portfolio mix of approximately 55%-65% in equity securities, 30%-35% in fixed income securities and 0%-15% in other securities.  
As of December 31, 2020, the Company had approximately 56% of its pension assets in equity securities, 28% in fixed income 
securities and 16% in other securities. 

The  Company  recognized  pension  expense  of  $18.4  million  in  2020  as  compared  to  $12.6  million  in  2019.    Accounting 
guidance on retirement benefits requires companies to discount future benefit obligations back to today’s dollars using a discount rate 
that is based on high-quality fixed-income investments.  A decrease in the discount rate increases the pension benefit obligation, while 
an increase in the discount rate decreases the pension benefit obligation.  This increase or decrease in the pension benefit obligation is 
recognized in Accumulated other comprehensive income (loss) and subsequently amortized into earnings as an actuarial gain or loss.  
The guidance also requires companies to use an expected long-term rate of return on plan assets for computing current year pension 
expense.  Differences between the actual and expected returns are also recognized in Accumulated other comprehensive income (loss) 
and  subsequently  amortized  into  earnings  as  actuarial  gains  and  losses.    At  the  end  of  2020,  total  actuarial  losses  recognized  in 
Accumulated other comprehensive income (loss) for pension plans were ($119.1) million as compared to ($99.7) million in 2019.  The 
majority  of  the  actuarial  losses  were  due  to  decreases  in  the  discount  rate  and  lower  actual  rates  of  return  on  assets  than  expected 
during the financial crisis of 2008. 

In 2020, included in other comprehensive income, is a net loss of $24.5 million ($18.7 million after-tax) primarily due to a 
change in discount rates.  In 2019, a net loss of $21.2 million ($16.1 million after-tax) was recorded in other comprehensive income, 
primarily  due  to  a  change  in  discount  rates.  In  2018,  a  net  loss  of  $21.6  million  ($16.9  million  after-tax)  was  recorded  in  other 
comprehensive income, primarily due to a change in discount rates and updated mortality tables. 

Actuarial  losses  for  pensions  will  be  impacted  in  future  periods  by  actual  asset  returns,  discount  rate  changes,  actual 
demographic experience and other factors that  impact these expenses.   These  losses, reported in Accumulated  other comprehensive 
income  (loss),  will  generally  be  amortized  as  a  component  of  net  periodic  benefit  cost  on  a  straight-line  basis  over  the  average 
remaining service period of active employees expected to receive benefits under the benefit plans.  At the end of 2020, the average 
remaining service period of active employees or life expectancy for fully eligible employees was 9 years.   

For a detailed discussion on the application of these and other accounting policies, see "Summary of Significant Accounting 
Policies"  in  Note  1  to  the  Consolidated  Financial  Statements.  This  discussion  and  analysis  should  be  read  in  conjunction  with  the 
consolidated financial statements and related notes included elsewhere in this report. 

Inflation 

While  inflation  historically  has  not  had  a  material  impact  on  the  Company,  our  financial  performance  could  be  adversely 
affected by increases in energy and commodity prices. 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  lime  and  energy  prices.  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 a portion of these escalating costs, but there can be no assurance that we will be able to recover increasing costs through such 
negotiations. 

Cyclical Nature of Customers' Businesses 

The bulk of our sales within Specialty Minerals,  Performance  Materials and Refractories  segments are to  customers in  the 
paper manufacturing, metalcasting, steel manufacturing and construction industries, which have historically been cyclical. The pricing 
structure  of  some  of  our  long-term  PCC  contracts  makes  our  PCC  business  less  sensitive  to  declines  in  the  quantity  of  product 
purchased. In addition, our customers’ demand for our Energy Services segments products and services are affected by oil and natural 
gas  production  activities,  which  are  heavily  influenced  by  the  benchmark  price  of  these  commodities.  Oil  and  natural  gas  prices 
decreased significantly between 2014 through 2017 and again in 2020, which has caused exploration companies to reduce their capital 
expenditures and production and exploration activities. This has had the effect of decreasing the demand and increasing competition 
for  the  services  we  provide.  We  cannot  predict  the  economic  outlook  in  the  countries  in  which  we  do  business,  nor  in  the  key 
industries we serve.

Recently Issued Accounting Standards 

Changes  to  accounting  principles  generally  accepted  in  the  United  States  of  America  (U.S.  GAAP)  are  established  by  the 
Financial  Accounting  Standards  Board  (FASB)  in  the  form  of  accounting  standards  updates  (ASUs)  to  the  FASB’s  Accounting 
Standards Codification. The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and 
determined to be either not applicable or are expected to have minimal impact on our consolidated financial position and results of 
operations. 

Investments - Equity Securities, Investments - Equity Method and Joint Ventures, and Derivatives and Hedging 

In January 2020, the FASB issued ASU 2020-01, “Investments - Equity Securities, Investments - Equity Method and Joint 
Ventures,  and  Derivatives  and  Hedging”,  which  addresses  the  accounting  for  the  transition  into  and  out  of  the  equity  method  and 
measuring certain purchased options and forward contracts to acquire investments.  The standard is effective for interim and annual 
periods  beginning  on or  after  December  15,  2020.    The  adoption  of  this  standard  is  not  expected  to have  a  material impact  on  the 
Company’s financial statements. 

Adoption of ASU 2016-13 Measurement of Credit Losses on Financial Instruments 

In  June  2016,  the  FASB  issued  ASU  2016-13,  “Measurement  of  Credit  Losses  on  Financial  Instruments”,  which  replaces 
existing incurred loss impairment guidance and establishes a single allowance framework for financial assets carried at amortized cost.  
The  Company  adopted  this  guidance  on  January  1,  2020  using  a  modified  retrospective  transition  method.    The  Company  did  not 
record a cumulative-effect adjustment upon adoption of this standard.  Adoption of this standard did not have a material impact on the 
Company’s consolidated financial statements. 

Adoption of ASU 2018-14 Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans 

In  August  2018,  the  FASB  issued  ASU  2018-14,  “Disclosure  Framework  -  Changes  to  the  Disclosure  Requirements  for 
Defined  Benefit  Plans”,  which  modifies  the  disclosure  requirements  for  employers  that  sponsor  defined  benefit  pension  or  other 
postretirement plans.  The Company adopted this guidance on January 1, 2020 on a retrospective basis and has updated the disclosures 
contained  in  Note  17  to  the Company's  Consolidated  Financial  Statements.  Other  than  the  modification  of  certain  disclosures,  this 
guidance did not impact the Company's consolidated financial statements. 

Item 7A.  Quantitative and Qualitative Disclosures about Market Risk 

We are exposed to market risk from fluctuations in foreign currency exchange rates, interest rates and credit risk. We use a 
variety of practices to manage these market risks, including derivative financial instruments when appropriate. Our treasury and risk 
management policies prohibit us from using derivative instruments for trading or speculative purposes. We also do not use leveraged 
derivative instruments or derivatives with complex features. 

Exchange Rate Sensitivity 

As we operate in over 30 countries with many international subsidiaries, we are exposed to currency fluctuations related to 
manufacturing and selling our products and services. This foreign currency risk is diversified and involves assets, liabilities and cash 
flows denominated in currencies other than the U.S. Dollar (USD). 

We  manage  our  foreign  currency  exchange  risk  in  part  through  operational  means,  including  managing  same  currency 
revenues versus same currency costs, as well as, same currency assets versus same currency liabilities.  We also have subsidiaries with 
the  same  currency  exposures  which  may  offset  each  other,  providing  a  natural  hedge  against  one  another’s  currency  risk.    When 
appropriate, we enter into derivative financial instruments, such as forward exchange contracts and cross currency interest rate swaps, 
to  mitigate  the  impact  of  foreign  exchange  rate  movements  on  our  operating  results.    The  counterparties  are  major  financial 
institutions.  Such forward exchange contracts would not subject us to additional risk from exchange rate because gains and losses on 
these contracts would offset losses and gains on the assets, liabilities, and transactions being hedged.  In the second quarter of 2018, 
the Company entered into a cross currency swap with a total notional value of $150 million.  The swap matures in May 2023.  The fair 
value of this swap at December 31, 2020, was an asset of $0.4 million. 

46 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Assets and liabilities of our international subsidiaries are translated to their parent company’s reporting currency at current 
exchange  rates  during  consolidation;  gains  and  losses  stemming  from  these  translations  are  included  as  a  component  of  Other 
Comprehensive Income and reported within Accumulated Comprehensive Income within our Consolidated Balance Sheets.  Income 
and  expenses  of  our  international  subsidiaries  are  translated  at  average  exchange  rates  for  the  period  and,  when  included  within 
retained earnings in the balance sheet at current exchange rates, the differences to those average exchange rates are included within 
Other Comprehensive Income and reported within Accumulated Comprehensive Income.  When our subsidiaries transact business in 
currencies other than their functional currency, those transactions are revalued in their functional currency and differences resulting 
from such revaluations are included within other non-operating income (deduction), net within our Consolidated Statement of Income. 

We  do  not  anticipate  that  near-term  changes  in  exchange  rates  will  have  a  material  impact  on  our future  earnings  or cash 
flows.  However, there can be no assurance that a sudden and significant change in the value of foreign currencies would not have a 
material adverse effect on our financial condition and results of operations. 

Interest Rate Sensitivity 

A portion of our long-term bank debt bears interest at variable rates (see Note 16 to the Consolidated Financial Statements) 
and our results of operations would be affected by interest rate changes to such bank debt outstanding.  The Company utilizes interest 
rate swaps to limit exposure to market fluctuations on floating-rate debt.  During the second quarter of 2016, the Company entered 
into  a  floating  to  fixed  interest  rate  swap  for  an  initial  aggregate  notional  amount  of  $300  million.    The  fair  value  of  this  swap  at 
December 31, 2020, was a liability of less than $0.1 million.  In the second quarter of 2018, the Company entered into an additional 
floating to fixed interest rate swap for with a total notional value of $150 million.  The fair value of this swap at December 31, 2020, 
was a liability of $7.7 million.  An immediate 10% increase  in the  interest  rates  would not have a  material  effect  on our results of 
operations over the next fiscal year.  A one percentage point change in interest rates would cost $1.5 million in incremental interest 
charges on an annual basis. 

Credit Risk 

We are exposed to credit risk on certain assets, primarily accounts receivable. We provide credit to customers in the ordinary 
course of business and perform ongoing credit evaluations. Concentrations of credit risk with respect to trade receivables are limited 
due  to  the  large  number  of  customers  comprising  our  customer  base.  We  currently  believe  our  allowance  for  doubtful  accounts  is 
sufficient to cover customer credit risks. Our accounts receivable  financial instruments are carried  at  amounts  that approximate fair 
value. 

Sovereign Debt Risk 

We do not have any material credit risk with sovereign governments as we do not sell our products to them. We do, however, 

sell to customers in these countries, but we believe our risk associated with these customers is not material.

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Note 1.  Summary of Significant Accounting Policies 

Business 

The  Company  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. 

Basis of Presentation 

The accompanying consolidated financial statements include  the accounts of  Minerals Technologies  Inc.  (the "Company"), 
its wholly and majority-owned subsidiaries, as well as variable interest entities for which the Company is the primary beneficiary. All 
intercompany balances and transactions have been eliminated in consolidation. 

Use of Estimates 

The  Company  employs  accounting  policies  that  are  in  accordance  with  U.S.  generally  accepted  accounting  principles  and 
require  management  to  make  estimates  and  assumptions  relating  to  the  reporting  of  assets  and  liabilities  and  the  disclosure  of 
contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses 
during the reported period. Significant estimates include those related to revenue recognition, valuation of long-lived assets, goodwill 
and  other  intangible  assets,  pension  plan  assumptions,  income  tax,  and  litigation  and  environmental  liabilities.  Actual  results  could 
differ from those estimates. 

Cash Equivalents and Short-term Investments 

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. 
Short-term investments consist of financial instruments, mainly bank deposits, with original maturities beyond three months, but less 
than twelve months.  Short-term investments amounted to $4.1 million and $1.6 million at December 31, 2020 and 2019, respectively. 
There were no unrealized holding gains and losses on the short-term bank investments held at December 31, 2020. 

Trade Accounts Receivable 

Trade accounts receivables are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts 
is the Company's best estimate of the amount of probable credit losses in the Company's existing accounts receivable.  The Company 
determines the allowance based on historical write-off experience and specific allowances for bankrupt customers.  The Company also 
analyzes the collection history and financial condition of its other customers, considering current industry conditions and determines 
whether an allowance needs to be established. The Company reviews its allowance for doubtful accounts monthly.  Past due balances 
over 90 days based on payment terms are reviewed individually for collectability.  Allowance for doubtful accounts was $15.0 million 
and  $12.9  million  at  December  31,  2020  and  2019,  respectively.  Account  balances  are  charged  off  against  the  allowance  after  all 
means of collection have been exhausted and the potential for recovery is considered remote.  The Company does not have any off-
balance-sheet credit exposure related to its customers. 

Inventories 

Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first-out (FIFO) method. 

Additionally,  items  such  as  idle  facility  expense,  excessive  spoilage,  freight  handling  costs,  and  re-handling  costs  are 
recognized  as  current  period  charges.    The  allocation  of  fixed  production  overheads  to  the  costs  of  conversion  are  based  upon  the 
normal capacity of the production facility.  Fixed overhead costs associated with idle capacity are expensed as incurred.

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Property, Plant and Equipment 

Property, plant and equipment are recorded at cost. Significant improvements are capitalized, while maintenance and repair 
expenditures are charged to operations as incurred.  The Company capitalizes interest cost as a component of construction in progress. 
The straight-line method of depreciation is used for substantially all of the assets for financial reporting purposes, except for mining 
related equipment which uses units-of-production method.  The annual rates of depreciation are 3% - 6.67% for buildings, 6.67% - 
12.5% for machinery and equipment, 8% - 12.5% for furniture and fixtures and 12.5% - 25% for computer equipment and software-
related  assets.    The  estimated  useful  lives  of  our  PCC  production  facilities  and  machinery  and  equipment  pertaining  to  our  natural 
stone mining and processing plants and our chemical plants are 15 years. 

Property, plant and equipment are depreciated over their useful lives. Useful lives are based on management's estimates of the 
period that the assets can generate revenue, which does not necessarily coincide with the remaining term of a customer's contractual 
obligation  to  purchase  products  made  using  those  assets.  The  Company's  sales  of  PCC  are  predominantly  pursuant  to  long-term 
evergreen contracts, initially ten years in length, with paper mills at which the Company operates satellite PCC plants. The terms of 
many of  these  agreements have  been  extended,  often  in  connection  with  an  expansion  of  the  satellite  PCC  plant.  Failure of  a  PCC 
customer to renew an agreement or continue to purchase PCC from a Company facility could result in an impairment of assets charge 
or accelerated depreciation at such facility. 

Depletion of mineral reserves is determined on a unit-of-extraction basis for financial reporting purposes, based upon proven 

and probable reserves, and generally on a percentage depletion basis for tax purposes. 

Stripping Costs Incurred During Production 

Stripping costs are those costs incurred for the removal of waste materials for the purpose of accessing ore body that will be 
produced  commercially.    Stripping  costs  incurred  during  the  production  phase  of  a  mine  are  variable  costs  that  are  included  in  the 
costs of inventory produced during the period that the stripping costs are incurred. 

Accounting for the Impairment of Long-Lived Assets 

Long-lived  assets  are  reviewed  for  impairment  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying 
amount of an asset may not be recoverable.  If events or changes in circumstances indicate that the carrying amount of an asset may 
not be recoverable, the Company estimates the undiscounted future cash flows (excluding interest), resulting from the use of the asset 
and  its  ultimate  disposition.    If  the  sum  of  the  undiscounted  cash  flows  (excluding  interest)  is  less  than  the  carrying  value,  the 
Company  recognizes  an  impairment  loss,  measured  as  the  amount  by  which  the  carrying  value  exceeds  the  fair  value  of  the  asset, 
determined principally using discounted cash flows. 

Goodwill and Other Intangible Assets 

Goodwill represents the excess of purchase price and related costs over the value assigned to the net tangible and identifiable 
intangible  assets  of  businesses  acquired.    Goodwill  is  not  amortized,  but  instead  assessed  for  impairment.    Intangible  assets  with 
estimable useful lives are amortized on a straight-line basis over their respective estimated lives to the estimated residual values, and 
reviewed for impairment. 

The  Company  performs  a  qualitative  assessment  for  each  of  its  reporting  units  to  determine  if  the  two-step  process  for 
impairment testing is required.  If the Company determines that it is more likely than not that the fair value of a reporting unit is less 
than its carrying amount, the Company would then evaluate the recoverability of goodwill using a two-step impairment test approach 
at the reporting unit level. In the first step, the fair value for the reporting unit is compared to its book value including goodwill. In the 
case that the fair value of the reporting unit is less than book value, a second step is performed which compares the fair value of the 
reporting  unit's  goodwill  to  the  book  value  of  the  goodwill.    The  fair value  for  the  goodwill  is  determined  based on  the  difference 
between the fair values of the reporting unit and the net fair values of the identifiable assets and liabilities of such reporting unit.  If the 
fair value of the goodwill is less than the book value, the difference is recognized as impairment.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Investment in Joint Ventures 

The Company uses the equity method of accounting to incorporate the results of its investments in companies in which it has 
significant influence but does not control; and cost method of accounting in companies in which it cannot exercise significant control. 
The Company records the equity in earnings of its investments in joint ventures on a one-month lag. At December 31, 2020 and 2019, 
the book value of the Company’s equity method investments was $17.0 million and $16.1 million.  

Accounting for Asset Retirement Obligations 

The Company provides for obligations associated with the retirement of long-lived assets and the associated asset retirement 
costs. The fair value of a liability for an asset retirement obligation is recognized in the period in which it is incurred if a reasonable 
estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-
lived  asset.  The  Company  also  provides  for  legal  obligations  to  perform  asset  retirement  activities  where  timing  or  methods  of 
settlement are conditional on future events. 

The Company also records liabilities related to land reclamation as a part of the asset retirement obligations.  The Company 
mines  land  for  various  minerals  using  a  surface-mining  process  that  requires  the  removal  of  overburden.    In  many  instances,  the 
Company  is  obligated  to  restore  the  land  upon  completion  of  the  mining  activity.    As  the  overburden  is  removed,  the  Company 
recognizes this liability for land reclamation based on the estimated fair value of the obligation. The obligation is adjusted to reflect 
the passage of time and changes in estimated future cash outflows. 

Fair Value of Financial Instruments 

The recorded amounts of cash and cash equivalents, receivables, short-term borrowings, accounts payable, accrued interest, 
and variable-rate long-term debt approximate fair value because  of  the short  maturity  of those  instruments  or  the variable nature of 
underlying interest rates.  Short-term investments are recorded at cost, which approximates fair market value. 

Derivative Financial Instruments 

The Company records derivative financial instruments which are used to hedge certain foreign exchange risk at fair value on 

the balance sheet.  See Note 13 for a full description of the Company's hedging activities and related accounting policies. 

Revenue Recognition 

Revenue is recognized at the point in time when the customer obtains control of the promised goods or services in an amount 
that reflects the consideration we expect to receive in exchange for those goods or services.  The Company's revenues are primarily 
derived from the sale of products.  Our primary performance obligation is satisfied upon shipment or delivery to our customer based 
on written sales terms, which is also when control is transferred.  Revenues from sales of equipment are recorded upon completion of 
installation and transfer of control to the customer.  Revenues from services are recorded when the services are performed. 

In most of our PCC contracts, the price per ton is based upon the total number of tons sold to the customer during the year. 
Under those contracts, the price billed to the customer for shipments during the year is based on periodic estimates of the total annual 
volume that will be sold to the customer. Revenues are adjusted at the end of each year to reflect the actual volume sold.  There were 
no  significant  revenue  adjustments  in  the  fourth  quarter  of  2020  and  2019,  respectively.    We  have  consignment  arrangements  with 
certain  customers  in  our  Refractories  segment.    Revenues  for  these  transactions  are  recorded  when  the  consigned  products  are 
consumed by the customer. 

Revenues  within  our  Energy  Services  segment  is  service  based.    Certain  contracts  within  this  segment  are  long-term 
contracts.   Revenue where our performance obligations are satisfied in phases is recognized over time using certain input measures 
based on the measurement of the value transferred to the customer, including milestones achieved.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Foreign Currency 

The assets and liabilities of the Company's international subsidiaries are translated into U.S. dollars using exchange rates at 
the  respective  balance  sheet  date.    The  resulting  translation  adjustments  are  recorded  in  accumulated  other  comprehensive  income 
(loss) in shareholders' equity.  Income statement items are generally translated at monthly average exchange rates prevailing during 
the  period.    International  subsidiaries  operating  in  highly  inflationary  economies  translate  non-monetary  assets  at  historical  rates, 
while  net  monetary  assets  are  translated  at  current  rates,  with  the  resulting  translation  adjustments  included  in  net  income.    At 
December 31, 2020, the Company had no international subsidiaries operating in highly inflationary economies. 

Income Taxes 

Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between 
the  financial  statement  carrying  amounts  of  existing  assets  and  liabilities  and  their  respective  tax  bases.    Deferred  tax  assets  and 
liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered 
or settled.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes 
the enactment date. 

The  Company  operates  in  multiple  taxing  jurisdictions,  both  within  the  U.S.  and  outside  the  U.S.  In  certain  situations,  a 
taxing authority may challenge positions that the Company has adopted in its income tax filings.  The Company regularly assesses its 
tax position for such transactions and includes reserves for those differences in position.  The reserves are utilized or reversed once the 
statute of limitations has expired or the matter is otherwise resolved. 

The  application  of  income  tax  law  is  inherently  complex.  Laws  and  regulations  in  this  area  are  voluminous  and  are  often 
ambiguous.    As  such,  we  are  required  to  make  many  subjective  assumptions  and  judgments  regarding  our  income  tax  exposures. 
Interpretations of and guidance surrounding income tax laws and regulations change over time.  As such, changes in our subjective 
assumptions and judgments can materially affect amounts recognized in the consolidated balance sheets and statements of operations. 
The  Company's  accounting  policy  is  to  recognize  interest  and  penalties  as  part  of  its  provision  for  income  taxes.  See  Note  9  for 
additional detail on our uncertain tax positions. 

The accompanying financial statements do not include a provision for foreign withholding taxes on international subsidiaries' 

unremitted earnings, which are expected to be permanently reinvested overseas. 

Research and Development 

Research and development costs are expensed as incurred. 

Accounting for Stock-Based Compensation 

The Company recognizes compensation expense for share-based awards based upon the grant date fair value over the vesting 

period. 

Pension and Post-retirement Benefits 

The Company has defined benefit pension plans covering the majority of its employees.  The benefits are generally based on 

years of service and an employee's modified career earnings. 

The Company also provides post-retirement healthcare benefits for the majority of its retirees and employees in the United 
States.    The  Company  measures  the  costs  of  its  obligation  based  on  its  best  estimate.    The  net  periodic  costs  are  recognized  as 
employees render the services necessary to earn the post-retirement benefits.

Environmental 

Expenditures  that  relate  to  current  operations  are  expensed  or  capitalized  as  appropriate.    Expenditures  that  relate  to  an 
existing  condition  caused  by  past  operations  and  which  do  not  contribute  to  current  or  future  revenue  generation  are  expensed. 
Liabilities  are  recorded  when  it  is  probable  the  Company  will  be  obligated  to  pay  amounts  for  environmental  site  evaluation, 
remediation or related costs, and such amounts can be reasonably estimated. 

Earnings Per Share 

Basic  earnings  per  share  have  been  computed  based  upon  the  weighted  average  number  of  common  shares  outstanding 

during the period. 

Diluted  earnings  per  share  have  been  computed  based  upon  the  weighted  average  number  of  common  shares  outstanding 

during the period assuming the issuance of common shares for all potentially dilutive common shares outstanding. 

Subsequent Events 

The Company has evaluated for subsequent events through the date of issuance of its financial statements. 

Recently Issued Accounting Standards 

Changes  to  accounting  principles  generally  accepted  in  the  United  States  of  America  (U.S.  GAAP)  are  established  by  the 
Financial  Accounting  Standards  Board  (FASB)  in  the  form  of  accounting  standards  updates  (ASUs)  to  the  FASB’s  Accounting 
Standards Codification. The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and 
determined to be either not applicable or are expected to have minimal impact on our consolidated financial position and results of 
operations. 

Investments - Equity Securities, Investments - Equity Method and Joint Ventures, and Derivatives and Hedging 

In January 2020, the FASB issued ASU 2020-01, “Investments - Equity Securities, Investments - Equity Method and Joint 
Ventures,  and  Derivatives  and  Hedging”,  which  addresses  the  accounting  for  the  transition  into  and  out  of  the  equity  method  and 
measuring certain purchased options and forward contracts to acquire investments.  The standard is effective for interim and annual 
periods  beginning  on or  after  December  15,  2020.    The  adoption  of  this  standard  is  not  expected  to have  a  material impact  on  the 
Company’s financial statements. 

Adoption of ASU 2016-13 Measurement of Credit Losses on Financial Instrument 

In  June  2016,  the  FASB  issued  ASU  2016-13,  “Measurement  of  Credit  Losses  on  Financial  Instruments”,  which  replaces 
existing incurred loss impairment guidance and establishes a single allowance framework for financial assets carried at amortized cost.  
The  Company  adopted  this  guidance  on  January  1,  2020  using  a  modified  retrospective  transition  method.    The  Company  did  not 
record a cumulative-effect adjustment upon adoption of this standard.  Adoption of this standard did not have a material impact on the 
Company’s consolidated financial statements. 

Adoption of ASU 2018-14 Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans 

In  August  2018,  the  FASB  issued  ASU  2018-14,  “Disclosure  Framework  -  Changes  to  the  Disclosure  Requirements  for 
Defined  Benefit  Plans”,  which  modifies  the  disclosure  requirements  for  employers  that  sponsor  defined  benefit  pension  or  other 
postretirement plans.  The Company adopted this guidance on January 1, 2020 on a retrospective basis and has updated the disclosures 
contained  in  Note  17.  Other  than  the  modification  of  certain  disclosures,  this  guidance  did  not  impact  the  Company's  consolidated 
financial statements.

Note 2.  COVID-19 

In March 2020, the World Health Organization categorized the novel coronavirus (COVID-19) as a pandemic. Around the 
world, the Company has been closely adhering 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  have  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.  

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, 
affecting sales in our Specialty Minerals segment. 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, serviced by our Energy Services segment.  

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.  

On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) 
which includes modifications to the limitation on business interest expense and net operating loss provisions, and provides a payment 
delay of employer payroll taxes during 2020 after the date of enactment with 50% due by December 31, 2021 and the remaining 50% 
due by December 31, 2022. The CARES Act did not have a material impact on the Company’s consolidated financial statements. 

Note 3.  Leases 

We determine if an arrangement is a lease at inception.  The Company has operating leases for premises, equipment, rail cars 
and automobiles.  Our leases have remaining lease terms of 1 year to 50 years, some of which may include options to extend the leases 
further.  The  Company  considers  these  options  in  determining  the  lease  term  used  to  establish  the  right-of-use  assets  and  lease 
liabilities. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based upon the information 
available at commencement date, or as of implementation of ASC 842, in determining the present value of lease payments. 

Leases with an initial term of 12 months or less are not recorded on the balance sheet. We recognize lease expense for these 
leases on a straight-line basis over the lease term. Certain lease agreements contain both lease and non-lease components. We account 
for lease components together with non-lease components. 

Operating lease cost was $15.3 million and $16.6 million for the years ended December 31, 2020 and December 31, 2019, 

respectively. The components of lease costs are as follows:

Note 4.  Revenue from Contracts with Customers 

The Company’s revenues are primarily derived from the sale of products in product lines within our Performance Materials, 
Specialty  Minerals,  Refractories  and  Energy  Services  businesses.    Our  primary  performance  obligation  (the  sale  of  products)  is 
satisfied upon shipment or delivery to our customers based on written sales terms, which is also when control is transferred.  In most 
of our contracts in our Paper PCC product line, which is in our Specialty Minerals segment, the price per ton is based upon the total 
number of tons sold to the customer during the year.  Under these contracts, the price billed to the customer for shipments during the 
year is based on periodic estimates of the total annual volume that will be sold to such customer.  Revenues are adjusted at the end of 
each year to reflect the actual volume sold.   

Revenue  from  sales  of  equipment,  primarily  in  our  Refractory  products  product  line  within  our  Refractories  segment,  is 
recorded  upon  completion  of  installation  and  control  is  transferred  to  the  customer.    Revenue  from  services  is  recorded  when  the 
services  have  been  performed.    Included  within  our  Refractory  products  product  line  are  certain  consignment  arrangements  with 
certain  customers  in  our  Refractories  segment.    Revenues  for  these  transactions  are  recorded  when  the  consigned  products  are 
consumed by the customer and control is transferred. 

Revenue  from  long-term  construction,  primarily  in  our  Energy  Services  segment,  where  our  performance  obligations  are 
satisfied  in  phases,  is  recognized  over  time  using  certain  input  measures  based  on  the  measurement  of  the  value  transferred  to  the 
customer, including milestones achieved.

Note 5.  Business Combination 

On April 30, 2018, the Company completed the  acquisition  of  Sivomatic  Holding B.V.  (“Sivomatic”), a  leading European 
supplier of premium pet litter products. Sivomatic is a vertically integrated manufacturer, with production facilities in the Netherlands, 
Austria and Turkey. With a leading position in premier clumping products, Sivomatic’s product portfolio spans the range of pet litter 
derived  from  bentonite,  sourced  predominantly  from  wholly-owned  mines  in  Turkey.  The  results  of  Sivomatic  are  included  in  our 
Performance  Materials  segment.  Sivomatic  sales  of  $61.8  million  are  included  in  the  Company's  consolidated  results  for  the  year 
ended  December  31,  2018.    The  acquisition  was  financed  through  a  combination  of  cash  on  hand  and  borrowings  under  the 
Company’s credit facilities. The fair value of the total consideration transferred, net of cash acquired, was $122.5 million. 

The acquisition has been accounted for using the acquisition method of accounting, which requires, among other things, that 
we recognize the assets acquired and liabilities assumed at their respective fair values as of the acquisition date. As of April 30, 2019, 
the purchase price allocation has been finalized. 

The Company used the income, market, or cost approach (or a combination thereof) for the preliminary valuation and used 
valuation inputs and analyses that were based on market participant assumptions.  Market participants are considered to be buyers and 
sellers unrelated to the Company in the principal or most advantageous market for the asset or liability.  For certain items, the carrying 
value was determined to be a reasonable approximation of fair value based on the information available. 

Goodwill was calculated as the excess of the consideration transferred over the assets acquired and represents the estimated 
future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The 
allocation was completed during the second quarter of 2019.  Goodwill recognized as a result of this acquisition is not deductible for 
tax purposes. 

In  connection  with  the  acquisition,  the  Company  recorded  an  additional  deferred  tax  liability  of  $18.8  million  with  a 
corresponding  increase  to  goodwill.  The  increase  in  deferred  tax  liability  represents  the  tax  effect  of  the  difference  between  the 
estimated assigned fair value of the tangible and intangible assets and the tax basis of such assets. 

Mineral  rights  were  valued using  discounted  cash flow  method.  Plant,  property  and  equipment  were  valued  using  the  cost 

method adjusted for age and deterioration.  

Intangible  assets  acquired  mainly  include  tradenames  and  customer  relationships.  Both  tradenames  and  customer 

relationships have an estimated useful life of approximately 20 years.  

The  Company  did  not  present  pro  forma  and  other  financial  information  for  the  Sivomatic  acquisition,  as  this  is  not 

considered to be a material business combination. 

Note 6.  Restructuring and Other Items, net 

During the third quarter of 2020, Domtar Corporation  announced the permanent  shut down  of their  previously idled paper 
machine at their mill in Ashdown, Arkansas.  As a result, the Company recorded a non-cash asset write-down charge of $1.1 million 
for its Paper PCC satellite facility at this mill. 

During the second quarter of 2020, Verso Papers announced they would be idling two of their paper mills indefinitely.  As a 
result, the Company recorded a non-cash asset write-down charge of $6.0 million and $0.3 million in severance related costs for its 
Paper PCC satellite facilities at these mills.  The Company also recorded lease termination costs at one of these closed mills. 

During the second quarter of 2019, the Company initiated a restructuring and cost savings program to better align our costs 
and organizational structure with the current market environment.  The Company recorded a $7.5 million non-cash asset write-down 
charge related to facilities and equipment no longer operating and deemed to be held for sale or discontinued and $5.7 million in other 
restructuring costs.

Note 7.  Stock-Based Compensation 

At the Company’s 2020 Annual Meeting of Stockholders, the Company’s stockholders ratified the adoption of an amendment 
and restatement of the Company’s 2015 Stock Award and Incentive Plan (the “2015 Plan”), which provides for grants of incentive and 
non-qualified stock options, restricted stock, stock appreciation rights, stock awards or performance unit awards.  This amendment and 
restatement increased the number of shares available for issuance pursuant to the 2015 Plan by 1,300,000 shares. The amendment and 
restatement also removed references to sections of the Internal Revenue Code that no longer apply, added a one-year minimum vesting 
requirement for all equity awards, subject to an exception of up to 5% of total shares available, and prohibited payment of dividends or 
dividend equivalents on unvested awards.  Finally, the amendment and restatement also revised the definition of “change in control” 
in the 2015 Plan. The amendment and restatement of the Company’s 2015 Plan by the Company’s stockholders applies to all awards 
granted under the 2015 Plan after March 11, 2020; awards granted prior to such date are governed by the 2015 Plan as in effect prior 
to the adoption of such changes (or, for awards granted prior to May 2015, by the 2001 Stock Award and Incentive Plan, as amended 
and restated (together with the 2015 Plan, the "Plans")).  

The Plans are administered by the Compensation Committee of the Board of Directors. Stock options granted under the Plans 
generally have a ten year term.  The exercise price for stock options are at prices at or above the fair market value of the common 
stock on the date of the grant, and each award of stock options will vest ratably over a specified period, generally three years. 

Stock-based compensation expense is recognized in the consolidated financial statements for stock options based on the grant 

date fair value. 

Net income for years ended 2020, 2019 and 2018 include $4.6 million, $4.8 million and $4.2 million pre-tax compensation 
costs,  respectively,  related  to  stock  option  expense  as  a  component  of  marketing  and  administrative  expenses.    All  stock  option 
expense is recognized in the consolidated statements of operations.  The related tax benefit included in the statement of income on the 
non-qualified stock options was $1.2 million, $1.3 million and $1.1 million for 2020, 2019 and 2018, respectively. 

Stock Options 

The fair value of options granted is estimated on the date of grant using the Black-Scholes valuation model. Compensation 
expense is recognized only for those options expected to vest, with forfeitures estimated at the date of grant based on the Company's 
historical experience and future expectations. The forfeiture rate assumption used for the periods ended December 31, 2020, 2019 and 
2018 was 8.45%, 8.85% and 8.20%, respectively. 

The weighted average grant date fair value for stock options granted during the years ended December 31, 2020, 2019 and 
2018 was $18.99, $18.86 and $25.79, respectively. The weighted average grant date fair value for stock options vested during 2020, 
2019  and  2018  was  $23.85,  $22.46  and  $21.33,  respectively.  The  total  intrinsic  value  of  stock  options  exercised  during  the  years 
ended December 31, 2020, 2019 and 2018 was $2.3 million, $2.2 million and $3.3 million, respectively. 

The fair value for stock awards was estimated at the date of grant using the Black-Scholes option valuation model with the 

following weighted average assumptions for the years ended December 31, 2020, 2019 and 2018:

The expected term of the options represents the estimated period of time until exercised and is based on historical experience 
of  similar  awards,  based  upon  contractual  terms,  vesting  schedules,  and  expectations  of  future  employee  behavior.  The  expected 
stock-price volatility is based upon the historical and implied  volatility of the Company's stock.  The  interest rate  is based  upon the 
implied yield on U.S. Treasury bills with an equivalent remaining term. Estimated dividend yield is based upon historical dividends 
paid by the Company.

The Company has granted key employees rights to receive shares of the Company's common stock pursuant to the Plan. The 
rights  will  be  deferred  for  a  specified  number  of  years  of  service,  subject  to  restrictions  on  transfer  and  other  conditions. 
Compensation expense for these shares is recognized over the vesting period. The Company granted 108,212 shares, 116,901 shares 
and 69,361 shares for the periods ended December 31, 2020, 2019 and 2018, respectively. The fair value was determined based on the 
market value of unrestricted shares. As of December 31, 2020, there was unrecognized stock-based compensation related to restricted 
stock of $6.4 million, which will be recognized over approximately the next three years. The compensation expense amortized with 
respect to all units was approximately $5.6 million, $5.2 million and $4.4 million for the periods ended December 31, 2020, 2019 and 
2018,  respectively.  In  addition,  the  Company  recorded  reversals  of  $2.3  million,  $1.9  million  and  $2.4  million  for  periods  ended 
December 31, 2020, 2019 and 2018, respectively, related mostly to the conversion of restricted stock for tax withholding purposes. 
Such costs and reversals are included in marketing and administrative expenses.

Note 9.  Income Taxes 

The  U.S.  Tax  Cuts  and  Jobs  Act  (“U.S.  Tax  Reform”),  enacted  in  December  2017,  significantly  changes  U.S.  corporate 
income tax laws by, among other things, reducing the U.S. corporate income tax rate to 21% starting in 2018 and creating a territorial 
tax  system  with  a  one-time  mandatory  tax  on  previously  deferred  foreign  earnings  of  U.S.  subsidiaries.  Under  U.S.  GAAP 
(specifically, ASC Topic 740), the effects of changes in tax rates and laws on deferred tax balances are recognized in the period in 
which the new legislation is enacted. 

During 2018, we recorded a benefit of $4.4 million as a measurement period adjustment to the one-time mandatory tax on 
previously deferred earnings of non-U.S. subsidiaries.  The accounting for income tax effects of U.S. Tax Reform is complete based 
on additional tax regulations available as of December 31, 2018. Amounts recorded during 2018 and 2017, respectively, are reflected 
within the provision for income taxes in the Consolidated Statement of Income. 

Additionally, U.S. Tax Reform subjects a U.S. shareholder to current tax on global intangible low-taxed income ("GILTI") 
earned  by  certain  foreign  subsidiaries.  We  have  elected  to  not  recognize  deferred  taxes  for  temporary  differences  until  such 
differences reverse as GILTI in future years.

The Company has $31.1 million  of deferred  tax  assets arising  from  tax loss  carry forwards  which  will be realized through 
future operations. Carry forwards of approximately $17.6 million expire over the next 20 years, and $13.5 million can be utilized over 
an indefinite period. 

On December 31, 2020, the Company  had $7.6 million of total unrecognized  tax  benefits. Included in  this  amount were  a 
total of $5.1 million of unrecognized income tax benefits that, if recognized, would affect the Company's effective tax rate. While it is 
expected  that  the  amount  of  unrecognized  tax  benefits  will  change  in  the  next  12  months,  we  do  not  expect  the  change  to  have  a 
significant impact on the results of operations or the financial position of the Company.

The  Company  operates  in  multiple  taxing  jurisdictions,  both  within  and  outside  the  U.S.  In  certain  situations,  a  taxing 
authority may challenge positions that the Company has adopted in its income tax filings. The Company, with a few exceptions (none 
of which are material), is no longer subject to U.S. federal, state, local, and international income tax examinations by tax authorities 
for years prior to 2010. 

Net cash paid for income taxes were $28.5 million, $29.5 million and $43.8 million for the years ended December 31, 2020, 

2019 and 2018, respectively. 

The Company had approximately $460.1 million of foreign subsidiaries' undistributed earnings as of December 31, 2020. We

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Note 13.  Derivative Financial Instruments and Hedging Activities 

As a multinational corporation with operations throughout the world, the Company is exposed to certain market risks.  The 
Company  uses  a  variety  of  practices  to  manage  these  market  risks,  including,  when  considered  appropriate,  derivative  financial 
instruments.  The Company's objective is to offset gains and losses resulting from interest rates and foreign currency exposures with 
gains  and  losses  on  the  derivative  contracts  used  to  hedge them.    The  Company  uses  derivative  financial  instruments  only  for  risk 
management and not for trading or speculative purposes. 

By using derivative financial instruments to hedge exposures to changes in interest rates and foreign currencies, the Company 
exposes itself to credit risk and market risk.  Credit risk is the risk that the counterparty will fail to perform under the terms of the 
derivative contract.  When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit 
risk for the Company.  When the fair value of a derivative contract is negative, the Company owes the counterparty, and therefore, it 
does  not  face  any  credit  risk.    The  Company  minimizes  the  credit  risk  in  derivative  instruments  by  entering  into  transactions  with 
major financial institutions. 

Market risk is the adverse effect on the value of a financial instrument that results from a change in interest rates, currency 
exchange rates, or commodity prices.  The market  risk associated  with  interest rate  and forward exchange  contracts  is managed by 
establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken. 

Cash Flow Hedges 

For derivative instruments that are designated and qualify as cash flow hedges, the Company records the effective portion of 
the gain or loss in accumulated other comprehensive income (loss) as a separate component of shareholders' equity.  The Company 
subsequently  reclassifies  the  effective  portion  of  gain  or  loss  into  earnings  in  the  period  during  which  the  hedged  transaction  is 
recognized in earnings. 

The Company utilizes interest rate swaps to limit exposure to market fluctuations on floating-rate debt.  In the second quarter 
of 2018, the Company entered into a floating to fixed interest rate swap for a notional amount of $150 million.  The fair value of this 
swap is a liability of $7.7 million at December 31, 2020 and is recorded in other non-current liabilities on the Consolidated Balance 
Sheet.    In  addition,  in  the  second  quarter  of  2016,  the  Company  entered  into  a  floating  to  fixed  interest  rate  swap  for  an  initial 
aggregate notional amount of $300 million. The notional amount at December 31, 2020 was $29 million.  The fair value of this swap 
is a liability of less than $0.1 million at December 31, 2020 and is recorded in other current liabilities on the Consolidated Balance 
Sheet.  These interest rate swaps are designated as cash flow hedges.  The gains and losses associated with these interest rate swaps 
are recorded in accumulated other comprehensive income (loss).  

Net Investment Hedges 

To protect the value of our investments in our foreign operations against adverse changes in foreign currency exchange rates, 
the Company from time to time hedges a portion of our net investment in one or more of our foreign subsidiaries.  During the second 
quarter of 2018, the Company entered into a cross currency rate swap with a total notional value of $150 million to exchange monthly 
fixed-rate interest payments in U.S. dollars for monthly fixed-rate interest rate payments in Euros.  This contract matures in May 2023 
and requires the exchange of Euros and U.S. dollar principal payments upon maturity.  The fair value of this swap is an asset of $0.4 
million at December 31, 2020 and is recorded in other assets and deferred charges on the Consolidated Balance Sheet.  Changes in the 
fair  value  of  this  instrument  are  recognized  in  accumulated  other  comprehensive  income  (loss)  to offset  the  change  in  the  carrying 
amount  of  the  net  investment  being  hedged.    Amounts  are  reclassified  out  of  accumulated  other  comprehensive  income  (loss)  into 
earnings when the hedged net investment is either sold or substantially liquidated. 

Other 

The  Company  is  exposed  to  potential  gains  or  losses  from  foreign  currency  fluctuations  affecting  net  investments  and 
earnings  denominated  in  foreign  currencies.    The  Company  is  particularly  sensitive  to  currency  exchange  rate  fluctuations  for  the 
following currencies: British  pound  sterling (GBP), Chinese  renminbi (CNY), Euro, Malaysian  ringgit  (MYR),  Polish zloty (PLN), 
South African Rand (ZAR), Thai baht (THB) and Turkish lira (TRY).  When considered appropriate, the Company enters into foreign 
exchange derivative contracts to mitigate the risk of fluctuations on these exposures.  The Company does not designate these contracts 
for  hedge  accounting  treatment  and  the  changes  in  fair  value  of  these  contracts  are  recorded  in  earnings.    The  Company  recorded 
losses (gains) of $0.2 million, $2.1 million and $(0.7) million in other non-operating income (deductions), net within the Consolidated 
Statements of Income for the years ended 2020, 2019 and 2018 respectively. There were no open contracts at December 31, 2020 and 
December 31, 2019.

Note 14.  Fair Value of Financial Instruments 

Fair  value  is  an  exchange  price  that  would  be  received for  an  asset  or  paid  to  transfer  a  liability  (exit  price)  in  an  orderly 
transaction  between  market  participants  at  the  measurement  date.    The  Company  utilizes  market  data  or  assumptions  that  market 
participants would use in pricing the asset or liability.  The Company follows a three-tier fair value hierarchy, which prioritizes the 
inputs used in measuring fair value.  These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; 
Level  2,  defined  as  inputs  other  than  quoted  prices  in  active  markets  that  are  either  directly  or  indirectly  observable;  and  Level  3, 
defined  as  unobservable  inputs  about  which  little  or  no  market  data  exists,  therefore  requiring  an  entity  to  develop  its  own 
assumptions. 

Assets  and  liabilities  measured  at  fair  value  are  based  on  one  or  more  of  three  valuation  techniques.  The  three  valuation 

techniques are as follows: 

●  Market  approach  –  prices  and  other  relevant  information  generated  by  market  transactions  involving  identical  or 

comparable assets or liabilities. 

●  Cost approach – amount that would be required to replace the service capacity of an asset or replacement cost. 
● 

Income  approach  –  techniques  to  convert  future  amounts  to  a  single  present  amount  based  on  market  expectations, 
including present value techniques, option-pricing and other models. 

The Company primarily applies the income approach for foreign exchange derivatives for recurring fair value measurements 

and attempts to utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. 

The following table sets forth by level within the fair value hierarchy the Company's financial assets and liabilities accounted 
for at fair value on a recurring basis at the end of each of the past two years.  Assets and liabilities are classified in their entirety based 
on  the  lowest  level  of  input  that  is  significant  to  the  fair  value  measurement.    The  Company's  assessment  of  the  significance  of  a 
particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and 
their placement within the fair value hierarchy levels.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

The fair value of foreign exchange contracts is determined based on inputs that are readily available in public markets or can 
be  derived  from  information  available  in  publicly  quoted  markets  and  are  categorized  as  Level  2.    Deferred  compensation  and 
supplementary  pension  plan  assets  related  to  the  acquisition  of  AMCOL  businesses  and  are  valued  using  quoted  prices  for  similar 
assets in active markets. 

The Company does not have any financial assets or liabilities measured at fair value on a recurring basis categorized as Level 
3, except for pension assets discussed in Note 17, and there were no transfers in or out of Level 3 during the year ended December 31, 
2020 and 2019. There were also no changes to the Company's valuation techniques used to measure asset and liability fair values on a 
recurring basis. 

Note 15.  Financial Instruments and Concentrations of Credit Risk 

The following methods and assumptions were used to estimate the fair value of each class of financial instrument: 

Cash  and  cash  equivalents,  short-term  investments,  accounts  receivable  and  payable:    The  carrying  amounts  approximate 

fair value because of the short maturities of these instruments. 

Short-term  debt and other liabilities:  The carrying amounts  of short-term  debt and other  liabilities approximate fair value 

because of the short maturities of these instruments. 

Long-term debt:  The fair value of the long-term debt of the Company is estimated based on the quoted market prices for that 

debt or similar debt and approximates the carrying amount. 

Forward  exchange  contracts:  The  fair  value  of  forward  exchange  contracts  (used  for  hedging  purposes)  is  based  on 
information derived from active markets.  If appropriate, the Company would enter into forward exchange contracts to mitigate the 
impact  of  foreign  exchange  rate  movements  on  the  Company's  operating  results.  It  does  not  engage  in  speculation.    Such  foreign 
exchange contracts would offset losses and gains on the assets, liabilities and transactions being hedged. 

Credit risk:  The Company provides credit to customers in the ordinary course of business. The Company’s customer base is 
diverse and includes customers located throughout the world. Credit risk results from the possibility that a loss may occur from the 
failure of another party to perform according to the terms of the contracts.  The Company regularly monitors its credit risk exposures 
and takes steps to mitigate the likelihood of these exposures resulting in an actual loss.  The Company's extension of credit is based on 
an evaluation of the customer's financial condition and collateral is generally not required. 

The Company's bad debt expense for the years ended December 31, 2020, 2019 and 2018 was $2.6 million, $6.3 million and 

$3.2 million, respectively.

On  May  9,  2014,  in  connection  with  the  acquisition  of  AMCOL  International  Corporation  (“AMCOL”),  the  Company 
entered  into  a  credit  agreement  providing  for  a  $1,560  million  senior  secured  term  loan  facility  (the  “Term  Facility”)  and  a  $200 
million senior secured revolving credit facility (the “Revolving Facility” and, together with the Term Facility, the “Facilities”). 

On June 23, 2015, the Company entered into an amendment (the “First Amendment”) to the credit agreement to reprice the 
$1.378 billion then outstanding on the Term Facility. As amended, the Term Facility had a $1.078 billion floating rate tranche and a 
$300 million fixed rate tranche.  On February 14, 2017, the Company entered into an amendment (the “Second Amendment”) to the 
credit  agreement  to  reprice  the  $788  million  floating  rate  tranche  then  outstanding,  which  extended  the  maturity  and  lowered  the 
interest costs by 75 basis points.  On April 18, 2018, the Company entered into an amendment (the “Third Amendment”) to the credit 
agreement to refinance its then existing senior secured revolving credit facility. In connection with the Third Amendment, the existing 
senior secured revolving credit facility was replaced with a new revolving credit facility with $300 million of aggregate commitments 
(the  "Revolving  Credit  Facility"  and,  together  with  the  Term  Facility,  the  "Senior  Secured  Credit  Facilities").  Following  the 
amendments, the loans outstanding under the floating rate tranche of the Term Facility are scheduled to mature on February 14, 2024, 
and the loans outstanding (if any) and commitments under the Revolving Facility will mature and terminate, as the case may be, on 
April 18, 2023. Loans under the fixed rate tranche of the Term Facility were repaid in full in June 2020.  Loans under the floating rate 
tranche of the Term Facility bear interest at a rate equal to an adjusted LIBOR rate (subject to a floor of 0.75%) plus an applicable 
margin equal to 2.25% per annum. Loans under the Revolving Facility bear interest at a rate equal to an adjusted LIBOR rate plus an 
applicable margin equal to 1.625% per annum.  Such rates are subject to decrease by up to 25 basis points in the event that, and for so 
long as, the Company’s net leverage ratio (as defined in the credit agreement) is less than certain thresholds. The variable rate tranche 
has a 1% required amortization per year. The Company will pay certain fees under the credit agreement, including customary annual 
administration fees.  The obligations of the Company under the Senior Secured Credit Facilities are unconditionally guaranteed jointly 
and  severally  by,  subject  to  certain  exceptions,  all  material  domestic  subsidiaries  of  the  Company  (the  “Guarantors”)  and  secured, 
subject to certain exceptions, by a security interest in substantially all of the assets of the Company and the Guarantors. 

The  credit  agreement  contains  certain  customary  affirmative  and negative  covenants  that  limit  or  restrict  the  ability of  the 
Company  and  its  restricted  subsidiaries  to  enter  into  certain  transactions  or  take  certain  actions.  In  addition,  the  credit  agreement 
contains  a  financial  covenant  that  requires  the  Company,  if  on  the  last  day  of  any  fiscal  quarter  loans  or  letters  of  credit  were 
outstanding under the Revolving Facility (excluding up to $25 million of letters of credit), to maintain a maximum net leverage ratio 
(as defined in the credit agreement) of 3.50 to 1.00 for the four fiscal quarter period preceding such day.  As of December 31, 2020, 
there were no outstanding loans and $9.5 million  in letters  of  credit  outstanding under the  Revolving  Facility.   The Company is in 
compliance with all the covenants associated with the Revolving Facility as of the end of the period covered by this report.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

On  June  30,  2020,  the  Company  issued  $400  million  aggregate  principal  amount  of  5.0%  Senior  Notes  due  2028  (the 
"Notes").  The Notes were issued pursuant to an indenture, dated as of June 30, 2020, between the Company and The Bank of New 
York Mellon Trust Company, N.A., as trustee.   The Company used the net  proceeds  of its  offering of  the Notes to repay all  of  its 
outstanding loans under the fixed rate tranche of the Term Facility, repay all of its outstanding borrowings under its Revolving Credit 
Facility, and the remainder for general corporate purposes.   

The Notes bear an interest rate of 5.0% per annum payable semi-annually on January 1 and July 1 of each year, beginning on 
January 1, 2021.  The Notes are unconditionally guaranteed on a senior unsecured basis by each of the Company's existing and future 
wholly owned domestic restricted subsidiaries that is a borrower under or that guarantees the Company's obligations under its Senior 
Secured Credit Facilities or that guarantees the Company's or any of the Company's wholly owned domestic subsidiaries' long-term 
indebtedness in an aggregate amount in excess of $50 million. 

At any time and from time  to time  prior to July 1, 2023,  the Company may  redeem some or all of the Notes for cash at a 
redemption price equal to 100% of their principal amount, plus the “make-whole” premium described  in the Indenture and accrued 
and unpaid interest, if any, to, but excluding, the applicable redemption date. Beginning on July 1, 2023, the Company may redeem 
some or all of the Notes at any time and from time to time at the applicable redemption prices listed in the Indenture, plus accrued and 
unpaid interest, if any, to, but excluding, the applicable redemption date. In addition, at any time and from time to time prior to July 1, 
2023,  the  Company  may  redeem  up  to  40%  of  the  aggregate  principal  amount  of  the  Notes  with  funds  from  one  or  more  equity 
offerings  at  a  redemption  price  equal  to  105%  of  the  principal  amount  thereof,  plus  accrued  and  unpaid  interest,  if  any,  to,  but 
excluding, the applicable redemption date. 

If the Company experiences a change of control (as defined in the indenture), the Company is required to offer to repurchase 
the  Notes  at  101%  of  the  principal  amount  of  such  Notes,  plus  accrued  and  unpaid  interest,  if  any,  to,  but  excluding,  the  date  of 
repurchase. 

The indenture contains certain customary affirmative and negative covenants that limit or restrict the ability of the Company 

and its restricted subsidiaries to enter into certain transactions or take certain actions, as well as customary events of default. 

During 2020, the Company repaid $288 million on its Term Facility.  

As part of the Sivomatic acquisition, the Company assumed $10.7 million in long-term debt, recorded at fair value, consisting 
of two term loans, one of which matured in the third quarter of 2020 and the other of which matures in 2022.  These loans carry an 
interest rate of Euribor plus 2.0% and have quarterly repayments.  During 2020, the Company repaid $1.5 million on these loans. 

The Company has a committed loan facility in Japan.  As of December 31, 2020, there was an outstanding balance of $4.1 
million on this facility. Principal will be repaid in accordance with the payment schedules ending in 2021. The Company repaid $0.6 
million on this loan in 2020.   

As of December 31, 2020, the Company had $25.6 million in uncommitted short-term bank credit lines, none of which were 

in use.   

There were no short-term borrowings as of December 21, 2020 and there were $101.2 million in short-term borrowings as of 

December 31, 2019. The weighted average interest rate on short-term borrowings outstanding as December 31, 2019 was 3.9%. 

The aggregate maturities of long-term debt are as follows: $4.5 million in 2021; $0.2 million in 2022; $— million in 2023, 

$548.0 million in 2024; $0.0 million in 2025 and $400.0 million thereafter. 

During  2020,  2019  and  2018,  respectively,  the  Company  incurred  interest  costs  of  $40.7  million,  $46.0  million  and $48.6 
million, including $0.6 million, $0.6 million and $0.5 million, respectively, which were capitalized.  Interest paid approximated the 
incurred interest cost.

Note 17.  Benefit Plans 

Pension Plans and Other Postretirement Benefit Plans 

The Company and its subsidiaries have pension plans covering the majority of eligible employees on a contributory or non-
contributory basis.  Benefits under defined benefit plans are generally based on years of service and an employee's career earnings. 
Employees generally become fully vested after five years. 

The  Company  also  provides  postretirement  health  care  and  life  insurance  benefits  for  the  majority  of  its  U.S.  retired 
employees.  Employees are generally eligible for benefits upon retirement and completion of a specified number of years of creditable 
service.  The Company does not pre-fund these benefits and has the right to modify or terminate the plan in the future. 

The Company’s disclosures for the U.S. plans have been combined with those outside of the U.S. as the international plans 

do not have significantly different assumptions, and together represent less than 22% of our total benefit obligation. 

The following table set forth Company's pension obligation and funded status at December 31:

The accumulated benefit obligation for all defined benefit pension plans was $501.7 million and $450.5 million at December 
31,  2020  and 2019,  respectively.  The  increase  in  MTI's  pension  obligation  for  2020  is  primarily  attributable  to  the  decrease  in  the 
discount rate.  The accumulated benefit obligations and projected benefit obligations are in excess of the plan assets for each of the

Unrecognized prior service cost is amortized over the average remaining service period of each active employee. 

The Company's funding policy for U.S. plans generally is to contribute annually into trust funds at a rate that provides for 
future  plan  benefits  and  maintains  appropriate  funded  percentages.    Annual  contributions  to  the  U.S.  qualified  plans  are  at  least 
sufficient to satisfy regulatory funding standards and are not more than the maximum amount deductible for income tax purposes. The 
funding  policies  for  the  international  plans  conform  to  local  governmental  and  tax  requirements.  The  plans'  assets  are  invested 
primarily in stocks and bonds.

For 2020, 2019 and 2018, the discount rate was based on a Citigroup yield curve of high quality corporate bonds with cash 
flows matching our plans' expected benefit payments.  The expected return on plan assets is based on our asset allocation mix and our 
historical  return,  taking  into  account  current  and  expected  market  conditions.  The  actual  return/(loss)  on  pension  assets  was 
approximately 9% in 2020, 15% in 2019 and (5)% in 2018. 

The Company maintains a self-funded health insurance plan for its retirees.  This plan provided that the maximum health care 
cost trend rate would be 5%.  Effective June 2010, the Company amended its plan to change the eligibility requirement for retirees and 
revised its plan so that increases in expected health care costs would be borne by the retiree.

The investment strategy for pension plan assets is to maintain a broadly diversified portfolio designed to both preserve and 
grow plan assets to meet future plan obligations. The Company's average rate of return on assets from inception through December 31, 
2020 was approximately 9%. The Company’s assets are strategically allocated among equity, debt and other investments to achieve a 
diversification level that dampens fluctuations in investment returns.  The Company’s long-term investment strategy is an investment 
portfolio mix of approximately 55%-65% in equity securities, 30%-35% in fixed income securities and  0%-15% in other securities. 

Savings and Investment Plans 

The Company maintains a voluntary Savings and Investment Plan (a 401(k) plan) for most non-union employees in the U.S. 
Within  prescribed  limits,  the  Company  bases  its  contribution  to  the  Savings  and  Investment  Plan  on  employee  contributions.  The 
Company's contributions amounted to $5.2 million, $5.4 million and $5.4 million for the years ended December 31, 2020, 2019 and 
2018, respectively.

Note 18.  Contingencies 

The  Company  is  party  to  a  number  of  lawsuits  arising  in  the  normal  course  of  our  business.  Certain  of  the  Company’s 
subsidiaries are among numerous defendants in a number of cases seeking damages for exposure to silica or to asbestos containing 
materials. Most of these claims do not provide adequate information to assess their merits, the likelihood that the Company will be 
found liable, or the magnitude of such liability, if any.  We are unable to state an amount or range of amounts claimed in any of the 
lawsuits because state court pleading practices do not require identifying the amount of the claimed damage. The aggregate cost to the 
Company for the legal defense of these cases since inception continues to be insignificant. The majority of the costs of defense for 
these  cases,  excluding  cases  against  our  subsidiaries  AMCOL  International  Corporation  or  American  Colloid  Company,  which  we 
acquired  in  2014,  are  reimbursed  by  Pfizer  Inc.  pursuant  to  the  terms  of  certain  agreements  entered  into  in  connection  with  the 
Company’s initial public offering in 1992. The Company is entitled to indemnification, pursuant to agreement, for liabilities related to 
sales  prior  to  the  initial  public  offering.  The  Company  has  settled  only  one  silica  lawsuit,  for  a  nominal  amount,  and  no  asbestos 
lawsuits  to  date  (not  including  any  that  may  have  been  settled  by  AMCOL  or  American  Colloid  prior  to  completion  of  the 
acquisition). At this time, management anticipates that the amount of the Company’s liability, if any, and the cost of defending such 
claims, will not have a material effect on its financial position or results of operations.   

The Company and its subsidiaries are not party to any other material pending legal proceedings, other than routine litigation 

incidental to their businesses. 

Note 19.  Stockholders' Equity 

Capital Stock 

The Company's authorized capital stock consists of 100 million shares of common stock, par value $0.10 per share, of which 
33,882,187  shares  and  34,544,307  shares  were  outstanding  at  December  31,  2020  and  2019,  respectively,  and  1,000,000  shares  of 
preferred stock, none of which were issued and outstanding. 

Cash Dividends 

Cash  dividends  of  $6.8  million  or  $0.20  per  common  share  were  paid  during  2020.  In  January  2021,  a  cash  dividend  of 

approximately $1.7 million or $0.05 per share, was declared, payable in the first quarter of 2021. 

Stock Award and Incentive Plan 

At the Company’s 2020 Annual Meeting of Stockholders, the Company’s stockholders ratified the adoption of an amendment 
and restatement of the Company’s 2015 Stock Award and Incentive Plan (the “2015 Plan”), which provides for grants of incentive and 
non-qualified stock options, restricted stock, stock appreciation rights, stock awards or performance unit awards.  This amendment and 
restatement increased the number of shares available for issuance pursuant to the 2015 Plan by 1,300,000 shares. The amendment and 
restatement also removed references to sections of the Internal Revenue Code that no longer apply, added a one-year minimum vesting 
requirement for all equity awards, subject to an exception of up to 5% of total shares available, and prohibited payment of dividends or 
dividend equivalents on unvested awards.  Finally, the amendment and restatement also revised the definition of “change in control” 
in the 2015 Plan. The amendment and restatement of the Company’s 2015 Plan by the Company’s stockholders applies to all awards 
granted under the 2015 Plan after March 11, 2020; awards granted prior to such date are governed by the 2015 Plan as in effect prior 
to the adoption of such changes (or, for awards granted prior to May 2015, by the 2001 Stock Award and Incentive Plan, as amended 
and restated (together with the 2015 Plan, the "Plans")).  

The Plans are administered by the Compensation Committee of the Board of Directors. Stock options granted under the Plans 
generally have a ten year term. The exercise price for stock options are at prices at or above the fair market value of the common stock 
on the date of the grant, and each award of stock options will vest ratably over a specified period, generally three years.

Note 21.  Accounting for Asset Retirement Obligations 

The Company records asset retirement obligations in which the Company will be required to retire tangible long-lived assets. 
These are primarily related to its PCC satellite facilities and mining operations.  The Company has also recorded the provisions related 
to conditional asset retirement obligations at its facilities.  The Company has recorded asset retirement obligations at all of its facilities 
except where there are no contractual or legal obligations.  The associated asset retirement costs are capitalized as part of the carrying 
amount of the long-lived asset.

The  Company  mines  various minerals  using  a  surface  mining  process  that  requires  the removal  of  overburden.   In  certain 
areas  and  under various  governmental  regulations,  the  Company  is  obligated  to  restore  the  land  comprising  each  mining  site  to  its 
original  condition  at  the  completion  of  the  mining  activity.    This  liability  will  be  adjusted  to  reflect  the  passage  of  time,  mining 
activities, and changes in estimated future cash outflows. 

The  current  portion  of  the  liability  of  approximately  $0.4  million  is  included  in  other  current  liabilities  and  the  long-term 
portion of the liability of approximately $23.7 million is included in other non-current liabilities in the Consolidated Balance Sheet as

Note 22.  Segment and Related Information 

The Company determines its operating segments based on the discrete financial information that is regularly evaluated by its 
chief operating decision maker, our Chief Executive Officer, in deciding how to allocate resources and in assessing performance.  The 
Company's  operating  segments  are  strategic  business  units  that  offer  different  products  and  serve  different  markets.    They  are 
managed separately and require different technology and marketing strategies. 

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

●  The  Performance  Materials  segment  is  a  leading  global  supplier  of bentonite  and  bentonite-related  products,  chromite 
and leonardite.  This segment also provides products for non-residential construction, environmental and infrastructure 
projects worldwide, serving customers engaged in a broad range of construction projects. 

●  The Specialty Minerals segment produces and sells the synthetic mineral product precipitated calcium carbonate ("PCC") 
and  processed  mineral  product  quicklime  ("lime"),  and  mines  mineral  ores  then  processes  and  sells  natural  mineral 
products, primarily limestone and talc. 

●  The  Refractories  segment  produces  and  markets  monolithic  and  shaped  refractory  materials  and  specialty  products, 

services and application and measurement equipment, and calcium metal and metallurgical wire products. 

●  The Energy Services segment provides services to improve the production, costs, compliance, and environmental impact 
of activities performed in the oil and gas industry.  This segment offers a range of services for offshore filtration and well 
testing to the worldwide oil and gas industry. 

The accounting policies of the segments are the same as those described in the summary of significant accounting policies. 
The Company evaluates performance based on the operating income of the respective business units.  The costs deducted to arrive at 
operating profit do not include several items, such as net interest or income tax expense.  Depreciation expense related to corporate 
assets is allocated to the business segments and is included in their income from operations.    However, such  corporate  depreciable 
assets are not included in the segment assets.  Intersegment sales and transfers are not significant.

Report of Independent Registered Public Accounting Firm 

To the Shareholders and Board of Directors 
Minerals Technologies Inc.: 

Opinion on the Consolidated Financial Statements 
We have audited the accompanying consolidated balance sheets of Minerals Technologies Inc. and subsidiaries (the Company) as of 
December 31, 2020 and 2019, the related consolidated statements of income, comprehensive income, changes in shareholders’ equity, 
and cash flows for each of the years in the three-year period ended December 31, 2020, and the related notes and financial statement 
schedule (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all 
material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its 
cash  flows  for  each  of  the  years  in  the  three-year  period  ended  December 31,  2020,  in  conformity  with  U.S. generally  accepted 
accounting principles. 
We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States) 
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal 
Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our 
report dated February 19, 2021 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial 
reporting. 

Basis for Opinion 
These  consolidated  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an 
opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB 
and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB. 
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit 
to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to 
error  or fraud. Our audits included performing  procedures  to  assess the risks of  material  misstatement  of  the  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. We believe that our audits provide a reasonable basis for our opinion. 

Critical Audit Matter 
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: (1) relates to accounts or disclosures that are 
material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgment. The 
communication of a critical audit matter  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 separate opinions on the critical audit matter or on 
the accounts or disclosures to which it relates. 

Measurement of projected pension benefit obligations 
As  discussed  in  Note  1  and  Note  17  to  the  consolidated  financial  statements,  the  Company  estimates  the  liability  related  to  their 
pension plans using actuarial models that include assumptions about the Company’s discount rates. The Company’s projected pension 
benefit obligations were $534 million as of December 31, 2020. 
We identified the measurement of the Company’s projected pension benefit obligations as a critical audit matter. Specialized skills are 
required  to  understand  the  Company’s  assumptions.  In  particular,  especially  complex  auditor  judgement  is  required  to  assess  the 
discount rate used in the projected pension benefit obligations.  
The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the 
operating effectiveness of certain internal controls over the Company’s pension process, including a control related to the Company’s 
assessment of the discount rate utilized within the actuarial models. We obtained an understanding of the actuarial model used by the 
Company in selecting the discount rate for each plan and inquired as to whether there have been changes to this methodology in the 
current  year.  We  also  involved  an  actuarial  professional  with  specialized  skills  and  knowledge,  who  assisted  in  evaluating  the 
Company’s analysis of the discount rates and assessed the discount rates considering the timing and amount of benefit payments used 
in the determination of the projected pension benefit obligation. 

We have served as the Company’s auditor since 1992.

period  ended  December 31,  2020,  and  related  notes  and  financial  statement  schedule  (collectively,  the  consolidated  financial 
statements), and our report dated February 19, 2021 expressed an unqualified opinion on those consolidated financial statements. 

Basis for Opinion  

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of 
the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control 
Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based 
on  our  audit.  We  are  a  public  accounting  firm  registered  with  the  PCAOB  and  are  required  to  be  independent  with  respect  to  the 
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange 
Commission and the PCAOB. 

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit 
to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. 
Our audit 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 audit also included performing such other procedures as we considered necessary in the circumstances. 
We believe that our audit provides a reasonable basis for our opinion. 

Definition and Limitations of Internal Control Over Financial Reporting  

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting 
principles.  A  company’s  internal  control  over  financial  reporting  includes  those  policies  and  procedures  that  (1) pertain  to  the 
maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the 
company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in 
accordance  with  authorizations  of  management  and  directors  of  the  company;  and  (3) provide  reasonable  assurance  regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect 
on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections 
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management's Report On Internal Control Over Financial Reporting 

Management of Minerals Technologies Inc. is responsible for the preparation, integrity and fair presentation of its published 
consolidated financial statements. The financial statements have been prepared in accordance with U.S. generally accepted accounting 
principles and, as such, include  amounts based on judgments  and estimates made by  management. The  Company also  prepared the 
other  information  included  in  the  annual  report  and  is  responsible  for  its  accuracy  and  consistency  with  the  consolidated  financial 
statements. 

Management  is  also  responsible  for  establishing  and  maintaining  effective  internal  control  over  financial  reporting.  The 
Company's  internal  control  over  financial  reporting  includes  those  policies  and  procedures  that  pertain  to  the  Company's  ability  to 
record,  process,  summarize  and  report  reliable  financial  data.  The  Company  maintains  a  system  of  internal  control  over  financial 
reporting,  which  is  designed  to  provide  reasonable  assurance  to  the  Company's  management  and  board  of  directors  regarding  the 
preparation of reliable published financial statements and safeguarding of the Company's assets. The system includes a documented 
organizational  structure  and  division  of  responsibility,  established  policies  and  procedures,  including  a  code  of  conduct  to  foster  a 
strong ethical climate, which are communicated throughout the Company, and the careful selection, training and development of our 
people. 

The Board of Directors, acting  through  its Audit  Committee,  is responsible for  the oversight  of the  Company's  accounting 
policies,  financial  reporting  and  internal  control.  The  Audit  Committee  of  the  Board  of  Directors  is  comprised  entirely  of  outside 
directors  who  are  independent  of  management.  The  Audit  Committee  is  responsible  for  the  appointment  and  compensation  of  the 
independent registered public accounting firm. It meets periodically with management, the independent registered public accounting 
firm and the internal auditors to ensure that they are carrying out their responsibilities. The Audit Committee is also responsible for 
performing  an  oversight  role  by  reviewing  and  monitoring  the  financial,  accounting  and  auditing  procedures  of  the  Company  in 
addition  to  reviewing  the  Company's  financial  reports.  The  independent  registered  public  accounting  firm  and  the  internal  auditors 
have full and unlimited access to the Audit Committee, with or without management, to discuss the adequacy of internal control over 
financial reporting, and any other matters which they believe should be brought to the attention of the Audit Committee. 

Management recognizes that there are inherent limitations in the effectiveness of any system of internal control over financial 
reporting, including the possibility of human error and the circumvention or overriding of internal control. Accordingly, even effective 
internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation and may 
not  prevent  or  detect  misstatements.  Further,  because  of  changes  in  conditions,  the  effectiveness  of  internal  control  over  financial 
reporting may vary over time. 

The Company assessed its internal control system as of December 31, 2020 in relation to criteria for effective internal control 
over  financial  reporting  described  in  "Internal  Control  –  Integrated  Framework  (2013)"  issued  by  the  Committee  of  Sponsoring 
Organizations of the Treadway Commission. Based on its assessment, the Company has determined that, as of December 31, 2020, its 
system of internal control over financial reporting was effective. 

The  consolidated  financial  statements  have  been  audited  by  the  independent  registered public  accounting  firm,  which  was 
given  unrestricted  access  to  all  financial  records  and  related  data,  including  minutes  of  all  meetings  of  stockholders,  the  Board  of 
Directors and committees of the Board. Reports of the independent registered public accounting firm, which includes the independent 
registered public accounting firm's attestation of the effectiveness of the Company's internal control over financial reporting are also 
presented within this document.

Additional Information Regarding Non-GAAP Financial Measures (unaudited)  

The following is a presentation of the Company’s non-GAAP net income and operating income, excluding special items, 
and free cash flow for the years ended December 31, 2020 and December 31, 2019 and a reconciliation to GAAP net 
income  and  operating  income  and  cash  flow  from  operations,  respectively,  for  such  periods.  The Company’s 
management  believes  these  non-GAAP  measures  provide  meaningful  supplemental  information  regarding  its 
performance as inclusion of such special items are not indicative of the ongoing operating results and thereby affect the 
comparability  of results between  periods. The Company feels inclusion of these  non-GAAP measures also  provides 
consistency in its financial reporting and facilitates investors’ understanding of historic operating trends.
