A MESSAGE FROM  
ECOLAB’S LEAD  
INDEPENDENT DIRECTOR 

David W. MacLennan
LEAD INDEPENDENT DIRECTOR

Ecolab’s last century was characterized by innovation, growth and 
positive impact. 2023 was another successful year with successfully 
managed challenges and continued business growth.

effectiveness and independence of your Board of Directors very 
seriously. As Chair of the Governance Committee, I have also led 
ongoing efforts to maintain strong Board leadership, composition 
and refreshment.

It was early in the year that I was appointed as Ecolab’s lead 
independent director, replacing Jeffrey M. Ettinger. I would like to 
acknowledge Jeff and the many contributions he made to Ecolab’s 
Board as my predecessor. While I bring different experiences and 
insights to the position, I am also focused on delivering long-term 
value for our stockholders.

In 2024, we were excited to welcome Judson Althoff to the Board. 
His global, business and high-tech experience make him an 
excellent addition and we are sure to benefit from his artificial 
intelligence and cloud computing knowledge. We also thank  
our valued colleague, Barbara J. Beck, for her service, including  
her roles as Chair of the Governance Committee and the 
Compensation & Human Capital Management Committee.

As I look back on the previous year, your independent directors 
were deeply involved in the development and oversight of Ecolab’s 
business strategy. We focused on the successful assessment and 
mitigation of company risk, including the management of financial, 
business and sustainability risk. We also oversaw a renewed focus 
on cementing the company’s status as an innovation powerhouse. 
By focusing on market, enterprise and breakthrough innovations, 
we see Ecolab addressing critical customer needs and realizing 
significant new sales opportunities in the coming years.

By focusing on innovations, we see Ecolab 

Ecolab’s last century was characterized by 

innovation, growth and positive impact. The 

company has the strategy and leadership in place 

to continue this momentum and deliver strong 

returns for its stockholders.

It is the combined effect of this work that makes me proud of 
Ecolab’s continued progress in 2023. This is the message that 
I shared as I represented your interests in many stockholder 
engagements during the year. These conversations were often 
focused on Ecolab’s governance structure, board composition  
and refreshment, and the oversight of risk.

If these topics are also of interest to you, I invite you to review 
the updates and ongoing changes overseen by the Board’s 
committees, including the Compensation & Human Capital 
Management Committee.

I would also like to thank you, our stockholders, for your continued 
confidence and investment in Ecolab. Your support underpins our 
commitment to continued progress and innovation in the pursuit of 
sustainable long-term value creation.

HIGHLIGHTS 

Performance  
and growth across 
the business

Delivering on business, water and 
sustainability goals 

In what ended as the hottest year on record, there are real business 
and sustainability pressures on modern companies. The need for 
our unique water technologies and services, including Ecolab Water 
for Climate™, couldn’t be clearer. In 2023, Ecolab continued to grow 
its Ecolab Water for Climate program, which is designed to help 
customers advance sustainable business growth while meeting 
climate and water goals. The program works by improving how 
businesses heat, cool, treat and move water in their operations to 
deliver interconnected benefits. By leveraging the power of water, 
Ecolab Water for Climate is showing companies how they can lower 
water use, energy use, greenhouse gas emissions and overall costs, 
helping disprove the myth that sustainability and growth are at odds.

As one example, Ecolab estimates that more efficient water 
management in data centers can help lower water use by up to 
one-third while continuing to pursue growth, according to Ecolab 
modeling of 14 data centers. Our sights are set on continuing to 
demonstrate this value in our priority markets — Data Centers  
and Food & Beverage Manufacturing — and accelerate future  
growth opportunities.

   100 YEARS OF GROWTH AND POSITIVE IMPACT

Largest innovation pipeline in Ecolab history 
Our focus on meeting customer needs and delivering innovation 
took a huge step in 2023 with attention on delivering against market, 
enterprise and breakthrough innovations that could deliver $1.3 billion 
in projected sales over the next five years.

The focus on the growth engine of life sciences is top of mind in 2024. 
Our latest breakthrough innovation in our Life Sciences business is 
our suite of Purolite technologies, focused on resin-based separation, 
purification and extraction. This innovation pipeline focuses on the 
established, high-growth market of biological medicines, which are 
life-saving treatments for diseases such as multiple myeloma and 
other cancers, rheumatoid arthritis, Crohn’s Disease and Alzheimer’s. 
Purolite’s patented, proprietary chemical manufacturing technique 
creates uniformly sized-and-shaped resin beads necessary to purify 
each drug in a unique way. The combination of our patented resin 
beads with the unique binding chemistry results in high levels of 
process consistency for the customer and improved final drug 
recovery. This provides an advantage for traditionally hard-to-purify 
drugs, allowing new medicines to come to market and treat patients 
with unmet needs.

Our breakthrough innovation programs are found in each of our 
Global Industrial, Global Institutional & Specialty and Healthcare and 
Life Sciences businesses. These focus on our biggest opportunities, 
driven by the challenges ranging from labor shortages to climate 
change and water scarcity, microelectronics, biologics acceleration 
and data centers that face our customers — and all of us. 

Institutional business gains momentum, 
driving positive change 
A business synonymous with Ecolab’s 100-year history faced 
significant challenges when the global pandemic led to massive 
disruption across its customer markets. 2023 saw Ecolab’s Global 
Institutional & Specialty segment lead with a strong focus on new 
business gains, value-based pricing and efficiency improvement.

Our effort to become the world’s water company 

is led by our Global Industrial business, which 

delivered strong sales of $7.2 billion in 2023, an 

increase of 7%. 

As we kick off 2024, we are committed to helping to solve labor 
challenges through solution penetration. We will focus on driving growth 
through increased market penetration by delivering new innovation for 
our customers and protecting vital customer relationships.

Pest Elimination: $1 billion driver 
Science-based service. Data and insights. Expert innovation. This focus 
has enabled Pest Elimination to continue growing at a historic pace 
through 2023, an 11 percent increase in organic sales compared to 2022.

Pest Elimination’s strong and consistent platform delivers growth 
through innovation that benefits mission-critical segments and 
protects our customers’ brands and reputation.

Our strategic mindset is to move past simply pest control to end-to-end 
pest elimination programs, leveraging our expertise, data science and 
innovation. For example, Ecolab’s digitally enabled pest elimination 
solution connects equipment that monitors and detects rodent activity, 
leverages predictive analytics and develops a risk-based service plan 
designed to meet customers’ needs.

On deck for 2024: Building on the best year in Pest Elimination’s history 
and leveraging more innovative technology that allows Ecolab service 
specialists to more effectively and efficiently support our customers.

In 2023, Global Institutional & Specialty focused on transforming 
the business for growth, driving penetration for volume and 
creating breakthrough innovations. The $43-billion global market for 
institutional-type business remains focused on sustainability while 
addressing labor challenges, inflation and opportunities presented by 
new technology. 

Ecolab Science Certified is one such value program that helps 
customers attain their goals of talent retention, cost management 
and customer retention. In 2023, Ecolab effectively supported hotels 
like Wyndham in navigating this landscape. The 531 participating 
Wyndham locations saw a 21 percent increase in higher reviews and a 
29 percent decrease in negative cleanliness mentions six months after 
beginning the program compared to the same time frame a year prior.

These types of efforts in 2023 helped drive 

Institutional’s $5.0 billion in full-year organic sales 

and $823 million operating income, an increase of 
12% and 32% compared to the prior year.

The following description of our business is based upon our reportable segments as reported in our consolidated financial statements for 
the year ended December 31, 2023, which are located in Item 8 of Part II of this Form 10-K. Operating segments that share similar 
economic characteristics and future prospects, including the nature of the products and production processes, end-use markets, 
channels of distribution and regulatory environment, have been aggregated into three reportable segments: Global Industrial, Global 
Institutional & Specialty and Global Healthcare & Life Sciences. Operating segments that were not aggregated and do not exceed the 
quantitative criteria to be separately reported have been combined into Other. We provide similar information for Other as compared to 
our three reportable segments as we consider the information regarding its underlying operating segments useful in understanding our 
consolidated results. 

3 

Global Industrial 

This reportable segment consists of the Water, Food & Beverage and Paper operating segments, which provide water treatment and 
process applications, and cleaning and sanitizing solutions, primarily to large industrial customers within the manufacturing, food and 
beverage processing, transportation, chemical, primary metals and mining, power generation, global refining, petrochemical, pulp and 
paper industries. The underlying operating segments exhibit similar manufacturing processes, distribution methods and economic 
characteristics. Descriptions of the three operating segments which comprise our Global Industrial reportable segment follow below. 

Water 

Water serves customers across industrial and institutional markets. Within Water, our light industry markets include food and beverage, 
manufacturing and transportation, institutional clients including commercial buildings, hospitals, universities and hotels, and global high 
technology serving customers including data centers and microelectronics. Heavy industries served include power, chemicals and 
primary metals, mining and petroleum refining and fuels industry.  

Water provides water treatment products and technology programs for cooling water, wastewater, boiler water and process water 
applications. In addition to these solutions, we offer specialty programs to the petroleum and fuels industry – refining process 
applications, fuels and feedstocks additives. Our cooling water treatment programs are designed to control challenges associated with 
cooling water systems — corrosion, scale and microbial fouling and contamination — in open recirculating, once-through and closed 
systems. Our wastewater products and programs focus on improving overall plant economics, addressing compliance issues, optimizing 
equipment efficiency and improving operator capabilities and effectiveness. We provide integrated chemical and digitally-based solutions, 
process improvements and mechanical component modifications to optimize boiler performance and control corrosion and scale build-up. 
Our programs assist in more effectively managing water use for plant processes by optimizing the performance of treatment chemicals 
and equipment in order to minimize costs and maximize returns on investment.  

Our offerings include specialty products such as scale and corrosion inhibitors, antifoulants, pre-treatment solutions, membrane 
treatments, coagulants and flocculants, anti-foamers, hydrogen sulfide removal, cold flow improvers, lubricity inhibitors, crude desalting 
and reactive monomer inhibitors, as well as our 3D TRASARTM technologies, which combine chemistry, remote services and monitoring 
and control. We provide products and programs for water treatment and process applications aimed at combining environmental benefits 
with economic gains for our customers. Typically, water savings, energy savings and operating efficiency are among our primary sources 
of value creation for our customers, with product quality and production enhancement improvements also providing key differentiating 
features for many of our offerings. Our offerings are sold primarily by our corporate account and field sales employees. 

We believe we are one of the leading global suppliers of products and programs for chemical applications within the industrial water 
treatment and petroleum refining industries. 

Food & Beverage  

Food & Beverage provides cleaning and sanitation products and programs to facilitate the processing of products for human 
consumption. Food & Beverage provides detergents, cleaners, sanitizers, lubricants and animal health products, as well as cleaning 
systems, digitally-based dispensers, monitors and chemical injectors for the application of chemical products, primarily to dairy plants; 
dairy, swine and poultry farms; breweries and soft-drink bottling plants as well as meat, poultry and other food processors. Food & 
Beverage is also a leading developer and marketer of antimicrobial products used in direct contact with meat, poultry, seafood and 
produce during processing in order to reduce microbial contamination. Food & Beverage also designs, engineers and installs CIP 
(“clean-in-place”) process control systems and facility cleaning systems for its customer base. Water savings, energy savings, and 
operating efficiency are among our sources of value creation for our customers. Products for use in processing facilities are sold primarily 
by our corporate account and field sales employees, while products for use on farms are sold through dealers and independent, third-
party distributors. 

We believe we are one of the leading global suppliers of cleaning and sanitizing products to the dairy plant, dairy, swine and poultry farm, 
beverage/brewery, food, meat and poultry, and beverage/brewery processing industries. 

Paper 

Paper provides water and process applications for the pulp and paper industries, offering a comprehensive portfolio of programs that are 
used in all principal steps of the papermaking process and across all grades of paper, including graphic grades, board and packaging, 
and tissue and towel. While Paper provides its customers similar types of products and programs for water treatment and wastewater 
treatment as those offered by Water, Paper also offers two specialty programs that differentiate its offerings from Water—pulp 
applications and paper applications. Our pulp applications maximize process efficiency and increase pulp cleanliness and brightness in 
bleaching operations, as well as predict and monitor scaling potential utilizing on-line monitoring to design effective treatment programs 
and avoid costly failures. Our paper process applications focus on improving our customers’ operational efficiency, in part through water 
savings, energy savings and operating efficiency. Advanced digital sensing, monitoring and automation combine with innovative 
chemistries and detailed process knowledge to provide a broad range of customer solutions. Specialty products include flocculants, 
coagulants, dewatering aids and digester yield additives. Our offerings are sold primarily by our corporate account and field sales 
employees. 

We believe we are one of the leading global suppliers of water treatment products and process aids to the pulp and papermaking 
industry.

Global Institutional & Specialty 

This reportable segment consists of the Institutional and Specialty operating segments, which provide specialized cleaning and sanitizing 
products to the foodservice, hospitality, lodging, government, education and retail industries. The underlying operating segments exhibit 
similar manufacturing processes, distribution methods and economic characteristics. Descriptions of the two operating segments which 
comprise our Global Institutional & Specialty reportable segment follow below. 

Institutional 

Institutional sells specialized cleaners and sanitizers for washing dishes, glassware, flatware, foodservice utensils and kitchen equipment 
(“warewashing”), plus specialized cleaners for various applications throughout food service operations, on-premise laundries (typically 
used by hotel and healthcare customers) and general housekeeping functions. We also sell food safety products and equipment, water 
filters, dishwasher racks and related kitchen sundries to the foodservice, lodging, educational and healthcare industries. Institutional also 
provides pool and spa treatment programs for hospitality and other commercial customers, as well as a broad range of janitorial cleaning 
and floor care products and programs to customers in hospitality, healthcare and commercial facilities. Institutional develops various 
digital monitoring and chemical dispensing systems which are used by our customers to efficiently and safely dispense our cleaners and 
sanitizers, and through these products, systems and our on-site sales and service expertise, develop better results for our customers 
including water savings, energy savings and operating efficiency. In addition, Institutional markets a lease program comprised of energy-
efficient dishwashing machines, detergents, rinse additives and sanitizers, including full machine maintenance. Through our EcoSure 
Food Safety Management business, Institutional also provides customized on-site evaluations, training and quality assurance services to 
foodservice operations. With the Lobster Ink business, Institutional provides our customers with end-to-end digital training solutions 
designed to drive corrective actions and optimal frontline execution. 

Institutional sells its products and programs primarily through its direct field sales and corporate account sales personnel. Corporate 
account sales personnel establish relationships and negotiate contracts with larger multi-unit or “chain” customers. We also utilize 
independent, third-party foodservice, broad-line and janitorial distributors to provide logistics to end customers that prefer to work through 
these distributors. Many of these distributors also participate in marketing our product and service offerings to the end customers. 
Through our field sales personnel, we generally provide the same customer support to end-use customers supplied by these distributors 
as we do to direct customers. 

We believe we are one of the leading global suppliers of warewashing and laundry products and programs to the food service, hospitality 
and lodging markets. 

Specialty 

Specialty supplies cleaning and sanitizing products and related items primarily to regional, national and international quick service 
restaurant (“QSR”) chains and food retailers (i.e., supermarkets and grocery stores). Its products include specialty and general purpose 
hard surface cleaners, degreasers, sanitizers, polishes, hand care products and assorted cleaning tools and equipment which are 
primarily sold under the “Ecolab” and “Kay” brand names. QSR’s program also includes a lease program comprised of energy-efficient 
dishwashing machines, detergents, rinse additives and sanitizers, including full machine maintenance. Specialty’s cleaning and sanitation 
programs are customized to meet the needs of the market segments it serves and are designed to provide highly effective cleaning 
performance, promote food safety, reduce labor, water and energy costs and enhance user and guest safety. A number of dispensing 
options are available for products in the core product range. Specialty supports its product sales with training programs and technical 
support designed to meet the special needs of its customers. 

Both Specialty’s QSR business and its food retail business utilize their corporate account sales force which manages relationships with 
customers at the corporate and regional office levels (and, in the QSR market segment, at the franchisee level) and their field sales force 
which provides program support at the individual restaurant or store level. QSR customers are primarily supplied through third party 
distributors while most food retail customers utilize their own distribution networks. While Specialty’s customer base has broadened 
significantly over the years, Specialty’s business remains largely dependent upon a limited number of major QSR chains and franchisees 
and large food retail customers. 

Food Safety Solutions supplies a digital platform that combines software, hardware and multiple services to automate kitchen procedures 
for efficiency and compliance. It also offers a unique variety of products, tools and equipment for food preparation, food rotation labeling, 
temperature management, cleaning and employee safety across all food service customers.  

We believe we are one of the leading suppliers of cleaning and sanitizing products to the global QSR market and a leading supplier of 
cleaning and sanitizing products to the global food retail market.

Global Healthcare & Life Sciences 

This reportable segment consists of the Healthcare and Life Sciences operating segments, which provide specialized cleaning and 
sanitizing products to the healthcare, personal care and pharmaceutical industries. The underlying operating segments exhibit similar 
manufacturing processes, distribution methods and economic characteristics. Descriptions of the two operating segments which 
comprise our Global Healthcare & Life Sciences reportable segment follow below. 

Healthcare 

Healthcare provides infection prevention and surgical solutions to acute care hospitals, surgery centers and medical device Original 
Equipment Manufacturers (“OEM”). Healthcare’s proprietary infection prevention and surgical solutions (hand hygiene, hard surface 
disinfection, digital monitoring systems, instrument cleaning, patient drapes, equipment drapes and surgical fluid warming and cooling 
systems) are sold primarily under the "Ecolab," "Microtek," and “Anios” brand names to various departments within the acute care 
environment (Infection Control, Environmental Services, Central Sterile and Operating Room). Healthcare sells its products and programs 
principally through its field sales personnel and corporate account personnel but also sells through healthcare distributors.  

We believe we are one of the leading suppliers of infection prevention and surgical solutions in the United States and Europe. 

Life Sciences 

Life Sciences provides end-to-end cleaning and contamination control solutions to pharmaceutical and personal care manufacturers. 
These products are primarily sold under the “Ecolab” brand name, and include detergents, cleaners, sanitizers, disinfectants, surface 
wipes, as well as cleaning systems, electronic dispensers and chemical injectors for the application of chemical products. With the 
acquisition of Purolite, the portfolio now includes premium fluid treatment and purification solutions with a broad range of unique products 
sold under the “Purolite” brand name, particularly focusing on biopharma purification solutions, active pharmaceutical ingredients 
(“API’s”) and high value industrial applications. The Life Sciences portfolio also includes decontamination systems and services utilizing 
hydrogen peroxide vapor, which are sold under the “Bioquell” brand name. The pharmaceutical clean room environment is the primary 
area that Ecolab and Bioquell products are utilized. Purolite products are primarily used in the purification of biologic therapeutics, API’s 
and high value industrial applications. Products and programs are sold primarily through our field sales and corporate account personnel, 
and to a lesser extent through distributors. 

Life Sciences is comprised of customers and accounts related to manufacturing in the following industries: pharmaceutical, animal health 
and medicine, blood purification and dialysis, biologic products, cosmetics and medical devices. Our tailored, comprehensive solutions 
and technical know-how focus on ensuring product quality, safety and compliance standards are met while improving operational 
efficiency in customers’ cleaning, sanitation and disinfection processes. We believe we are one of the leading suppliers of process 
purification solutions in Europe and North America and of contamination control solutions in Europe, with a growing presence in North 
America and other regions.  

Other 

Other consists of the Pest Elimination, Textile Care and Colloidal Technologies Group operating segments. These operating segments 
do not meet the quantitative criteria to be separately reported. We disclose these operating segments within Other as we consider the 
information useful in understanding our consolidated results. 

Pest Elimination 

Pest Elimination provides services designed to detect, prevent, and eliminate pests such as rodents and insects in full-service and quick-
service restaurants, food and beverage processors, hotels, grocery operations and other commercial segments including education, life 
sciences and healthcare. 

In addition to the United States, which constitutes our largest operation, we operate in various countries in Asia Pacific, Greater China, 
Western Europe, Latin America, and Africa. 

We believe Pest Elimination is a leading service provider of effective, high-quality pest elimination programs that deliver high quality 
outcomes to commercial segments in the geographies it serves. 

Textile Care 

Textile Care provides products and services that manage the entire wash process through custom designed programs, premium 
products, dispensing equipment, water and energy management and reduction, and real time data management for large scale, complex 
commercial laundry operations including uniform rental, hospitality, linen rental and healthcare laundries. Textile Care’s programs are 
designed to meet our customers’ needs for exceptional cleaning, while extending the useful life of linen and reducing our customers’ 
overall operating costs. Products and programs are marketed primarily through our field sales employees and, to a lesser extent, through 
distributors. We believe we are one of the leading global suppliers in the laundry markets in which we compete. 

6 

Colloidal Technologies Group 

The Colloidal Technologies Group (“CTG”) produces and sells colloidal silica, which is comprised of nano-sized particles of silica in 
water. These products and associated programs are used primarily for binding and polishing applications. CTG serves customers across 
various industries, including semiconductor manufacturing, catalyst manufacturing, chemicals and aerospace component manufacturing. 

CTG incorporates strong collaboration with customers to develop customized solutions that meet the technical demands of their 
operations. Our silica-based applications are widely used for polishing of silicon wafers, semiconductor substrates and the precision 
surface finishing of optics, watch crystals and other glass components. We offer a variety of silica-based particles that can be used as 
binders in heterogeneous catalyst systems and as silica nutrients for manufacturing specialty zeolites. Our silica products are used 
worldwide as a binder for precision investment casting slurries, which ultimately facilitate the manufacture of near net-shape metal parts 
such as turbine blades and golf club heads.  

Our products are sold primarily by our corporate account employees. We believe we are one of the leading global suppliers of colloidal 
silica.  

Additional Information 

International Operations  

We directly operate in approximately 100 countries outside of the United States through wholly-owned subsidiaries or, in some cases, 
through a joint venture with a local partner. In certain countries, selected products are sold by our export operations to distributors, 
agents or licensees, although the volume of those sales is not significant in terms of our overall revenues. In general, our businesses 
conducted outside the United States are similar to those conducted in the United States. 

Our business operations outside the United States are subject to the usual risks of foreign operations, including possible changes in 
trade and foreign investment laws, international business laws and regulations, tax laws, currency exchange rates and economic and 
political conditions. The profitability of our international operations is generally lower than the profitability of our businesses in the United 
States, due to (i) the additional cost of operating in numerous and diverse foreign jurisdictions with varying laws and regulations, (ii) 
higher costs of importing certain raw materials and finished goods in some regions, (iii) the smaller scale of international operations 
where certain operating locations are smaller in size, and (iv) the additional reliance on distributors and agents in certain countries which 
can negatively impact our margins. Proportionately larger investments in sales and technical support are also necessary in certain 
geographies in order to facilitate the growth of our international operations. 

Competition 

In general, the markets in which the businesses in our Global Industrial reportable segment compete are led by a few large companies, 
with the rest of the market served by smaller entities focusing on more limited geographic regions or a smaller subset of products and 
services. Our businesses in this segment compete on the basis of their demonstrated value, technical expertise, innovation, digital 
technology, chemical formulations, global customer support, detection equipment, monitoring capabilities, and dosing and metering 
equipment. Through the combination of our digitally enabled end-to-end water management and hygiene solutions, data-driven insights 
and personalized service, our Global Industrial businesses deliver outcomes that help our customers optimize water and energy use, 
improve productivity, advance food safety, and achieve sustainability and net zero goals, while optimizing total cost of operations. 

The businesses in our Global Institutional & Specialty reportable segment and Other have two significant classes of competitors. First, we 
compete with a small number of large companies selling directly or through distributors on a national or international scale. Second, we 
have numerous smaller regional or local competitors which focus on more limited geographies, product lines and/or end-use customer 
segments. We believe we compete principally by providing superior value, premium customer support, training, service, and innovative 
and differentiated products to help our customers protect their brand reputation and improve their operational efficiency. 

Within the Global Healthcare & Life Sciences reportable segment, the Healthcare business competes geographically with companies 
primarily focused on a smaller range of product categories, with few globally scaled competitors. The Life Sciences business competes in 
the European market versus several mid-size and regional competitors and competes against two large and other mid-size or regional 
competitors in North America. Outside of North America and Europe competitors are much more fragmented and do not offer the same 
level of service or coverage as Ecolab. Our businesses in this segment compete by enabling our customers success through improved 
hygiene, digitally enabled programs in operating room and patient room space as well as a tailored approach to delivering key inputs that 
directly impact our customers patients globally. 

Sales 

Our products, systems and services are primarily marketed in domestic and international markets by our Company-trained direct field 
sales personnel who also advise and assist our customers in the proper and most efficient use of the products and systems in order to 
meet a full range of cleaning and sanitation, water treatment and process chemistry needs. Independent, third-party distributors and, to a 
lesser extent, sales agents, are utilized in several markets, as described in the segment descriptions found above. 

7 

Customers and Classes of Products 

We believe our business is not materially dependent upon a single customer. Additionally, although we have a diverse customer base 
and no customer or distributor constituted 10 percent or more of our consolidated revenues in 2023, 2022 or 2021, we do have 
customers and independent third-party distributors, the loss of which could have a material adverse effect on results of operations for the 
affected earnings periods; however, we consider it unlikely that such an event would have a material adverse impact on our financial 
position. No material part of our business is subject to renegotiation or termination at the election of a governmental unit. 

We sold one class of products within the Global Institutional & Specialty reportable segment which comprised 10% or more of 
consolidated net sales in the last three years. Sales of warewashing products were approximately 12%, 12%, and 10% of consolidated 
net sales in 2023, 2022 and 2021, respectively. 

Human Capital 

As of December 31, 2023, Ecolab employed approximately 48,000 employees, including approximately 26,000 sales and service and 
1,100 research, development, and engineering employees. Approximately 42% of the employees are employed in North America, 20% in 
Europe, 7% in Asia Pacific, 17% in Latin America, 7% in India, Middle East and Africa, and 7% in Greater China.  

We believe that doing the right thing, the right way, is good for business. We believe that driving performance and growing fast, we can 
deliver a net positive impact in our own operations and what we deliver for our customers. We are committed to developing a culture that 
is diverse, equitable, inclusive, and leverages our employees’ talents as we work together to serve the needs of our customers. We 
believe that our culture is more creative and helps deliver the innovation needed to grow our business. We believe in providing training 
and career development opportunities to all employees and in compensating and rewarding our employees equitably. 

Our commitment to the safety of our employees, contractors, and customers is evident in the way we operate, the products we develop, 
and the customers we serve. In addition, we are committed to promoting the health and well-being of our employees, our customers, and 
their customers by contributing to programs and initiatives that enhance the quality of life in the communities where they work and live. In 
support of these overall objectives, key areas of focus include:  

Diversity, Equity, and Inclusion: We have a long-standing belief that a diverse, equitable, and inclusive workforce is a strong foundation 
for the shared success of our employees, our company, our customers, and our communities. To build that strong foundation, we have 
worked to embed diversity and inclusion throughout our people processes, including in the areas of recruitment, retention, and 
development. To help guide our work and support our broad commitment to progress, Ecolab has a Diversity Council made up of senior 
leaders throughout our company and chaired by our CEO. We review with the Council, senior executives and business leads key metrics 
and practices, including diverse representation of backgrounds and experiences, along with many aspects of our recruiting and retention 
practices. These programs are designed to facilitate equitable employment opportunities, while promoting an inclusive workforce. 

We also have a vibrant and growing community of 11 Employee Resource Groups (“ERGs”) that are open to all, to help employees 
connect with colleagues, take part in career and leadership development experiences, and provide important insights in support of 
advancing our work in diversity, equity, and inclusion. These employee-led ERGs create community and focus on several dimensions of 
diversity, including gender, race/ethnicity, gender identity, sexual orientation, ability/disability, military service, generational, global, and 
career skill development. All employees are welcome and encouraged to join, participate, or become leaders and allies within any of our 
ERGs.  

Employee Training and Development: Ecolab’s growth has been characterized by a century of supporting customers by combining 
science, technology and innovation with the expertise of our associates. Beyond rigorous technical, functional, and business-specific 
training courses, our Global Corporate Flagship Development Programs for supervisors, managers and leaders are designed to deepen 
leadership capability and prepare potential successors for key leadership roles.  

Compensation and Benefits: Ecolab has a market-competitive and performance-based pay philosophy, and we believe in compensating 
our employees fairly and equitably. We are committed to rewarding and recognizing employees for their contributions to the success of 
the organization. This includes our global merit increase program and our short- and long-term variable pay programs, which include 
goals and targets that are tied to the success of the business. We test our pay and wage data against compensation surveys to align our 
pay with the competitive external market. In the U.S., we conduct pay equity studies, and we are in the process of expanding pay equity 
studies outside the U.S. 

Ecolab also provides market-competitive benefits based on country-specific needs and government requirements. While our benefits 
packages vary by market, they are designed to attract top talent and build long-term connections with our associates. Aligned to the 
applicable market and local regulations, elements of our benefits programs may include medical and dental insurance, retirement 
savings, employee stock purchase plan, paid time off, parental leave and adoption assistance, life and disability insurance, and employee 
assistance plans. 

8 

Safety, Health, and Wellness: At Ecolab, the safety of our employees and contractors is a top priority and is embedded into our company 
values. Our safety goals are simple: zero accidents, zero injuries, and zero violations. We communicate that this is a collective goal all 
employees commit to, own, and deliver on every day. Our leadership teams and a network of Safety, Health, and Environment 
professionals around the world support employees with robust safety programs, processes, and platforms. Understanding underlying and 
potential risks is a critical component to improving safety outcomes. Our Global Safety Dashboard tracks our performance on a range of 
leading and lagging safety indicators and helps us measure the effectiveness of our safety programs. 

Additionally, a Be Well Program is available to U.S. employees and their families to empower, educate and support their personal journey 
to overall well-being by making positive lifestyle choices while creating a culture of wellness throughout Ecolab. Over the last few years, 
we’ve expanded our offerings to include comprehensive child and elder caregiver resources to help employees balance the demands of 
work and personal responsibilities. Wellness initiatives are also underway outside the U.S. aligned to country-specific needs and market 
practices. 

Patents and Trademarks 

We own and license a number of patents, trademarks and other intellectual property, including intellectual property from our recent 
acquisition of Purolite. While we have an active program to protect our intellectual property by filing for patents or trademarks and 
pursuing legal action, when appropriate, to prevent infringement, except for the items listed below, we do not believe our overall business 
is materially dependent on any individual patent or trademark. 





Patents related to our TRASAR and 3D TRASAR technology, which are material to our Global Industrial reportable segment.
U.S. and foreign patents protect aspects of our key TRASAR and 3D TRASAR technology until at least 2024.

Trademarks related to Ecolab, Nalco and 3D TRASAR, which collectively are material to all of our reportable segments. The
Ecolab, Nalco and 3D TRASAR trademarks are registered or applied for in all of our key markets and we anticipate maintaining
them indefinitely.

Seasonality 

We experience variability in our quarterly operating results due to seasonal sales volume and business mix fluctuations in our operating 
segments. Part II, Item 8, Note 20, entitled “Quarterly Financial Data” of this Form 10-K is incorporated herein by reference.  

Investments in Equipment 

We have invested, and plan to continue to invest, in process control and monitoring equipment consisting primarily of systems used by 
customers to dispense our products as well as to monitor water systems. The investment in such equipment is discussed under the 
heading "Investing Activities" in Management's Discussion and Analysis of Financial Condition and Results of Operations of this Form 10-
K. 

Manufacturing and Distribution 

We manufacture most of our products and related equipment in Company-operated manufacturing facilities. Some products are also 
produced for us by third-party contract manufacturers. Other products and equipment are purchased from third-party suppliers. Additional 
information on product/equipment sourcing is found in the segment discussions above and additional information on our manufacturing 
facilities is located under Part I, Item 2. “Properties,” of this Form 10-K. 

Deliveries to customers are made from our manufacturing plants and a network of distribution centers and third-party logistics service 
providers. We use common carriers, our own delivery vehicles, and distributors for transport. Additional information on our plant and 
distribution facilities is located under Part I, Item 2. “Properties,” of this Form 10-K. 

Raw Materials 

Raw materials purchased for use in manufacturing our products are inorganic chemicals, including alkalis, acids, biocides, phosphonates, 
phosphorous materials, silicates and salts; and organic chemicals, including acids, alcohols, amines, fatty acids, surfactants, solvents, 
monomers and polymers. Healthcare purchases plastic films and parts to manufacture medical devices that serve the surgical and 
infection prevention markets. Pesticides used by Pest Elimination are purchased as finished products under contract or purchase order 
from the producers or their distributors. We also purchase packaging materials for our manufactured products and components for our 
specialized cleaning equipment and systems. We purchase more than 10,000 raw materials, with the largest single raw material 
representing approximately four percent of raw material purchases. Our raw materials, with the exception of a few specialized chemicals 
which we manufacture, are generally purchased on an annual contract basis and are ordinarily available in adequate quantities from a 
diverse group of suppliers globally. When practical, global sourcing is used so that purchasing or production locations can be shifted to 
control product costs. 

Research and Development 

Our research and development program consists principally of developing and validating the performance of new products, processes, 
techniques and equipment, improving the efficiency of those already existing, improving service program content, evaluating the 
environmental compatibility of products and technical support. Key disciplines include analytical and formulation chemistry, microbiology, 

9 

data science and predictive analytics, process and packaging engineering, digital and remote monitoring engineering and product 
dispensing technology. Substantially all of our principal products have been developed by our research, development and engineering 
personnel.  

We believe continued research and development activities are critical to maintaining our leadership position within the industry and will 
provide us with a competitive advantage as we seek additional business with new and existing customers.  

Joint Ventures 

Over time, we have entered into partnerships or joint ventures in order to meet local ownership requirements, to achieve quicker 
operational scale, to expand our ability to provide our customers a more fully integrated offering or to provide other benefits to our 
business or customers. During 2023, the impact on our consolidated net income of our joint ventures, in the aggregate, was 
approximately three percent. We will continue to evaluate the potential for partnerships and joint ventures that can assist us in increasing 
our geographic, technological and product reach. 

Environmental and Regulatory Considerations 

Our businesses are subject to various legislative enactments and regulations relating to the protection of the environment and public 
health. While we cooperate with governmental authorities and take commercially practicable measures to meet regulatory requirements 
and avoid or limit environmental effects, some risks are inherent in our businesses. Among the risks are costs associated with 
transporting and managing hazardous materials and waste disposal and plant site clean-up, fines and penalties if we are found to be in 
violation of law, as well as modifications, disruptions or discontinuation of certain operations or types of operations including product 
recalls and reformulations. Similarly, the need for certain of our products and services is dependent upon or might be limited by 
governmental laws and regulations. Changes in such laws and regulations, including among others, air, water, chemical and product 
regulations, could impact the sales of some of our products or services. In addition to an increase in costs of manufacturing and 
delivering products, a change in production regulations or product regulations could result in interruptions to our business and potentially 
cause economic or consequential losses should we be unable to meet the demands of our customers for products. 

Additionally, although we are not currently aware of any such circumstances, there can be no assurance that future legislation or 
enforcement policies will not have a material adverse effect on our consolidated results of operations, financial position or cash flows. 
Environmental and regulatory matters most significant to us are discussed below. 

Ingredient Legislation: Various laws and regulations have been enacted by state, local and foreign jurisdictions pertaining to 
the sale of products which contain phosphorous, volatile organic compounds, per- and polyfluoroalkyl substances (“PFAS”) or 
other ingredients that may impact human health or the environment. Under California Proposition 65, for example, label 
disclosures are required for certain products containing chemicals listed by California. Chemical management initiatives that 
promote pollution prevention through research and development of safer chemicals and safer chemical processes are being 
advanced by several states.  

Environmentally preferable purchasing programs for cleaning products have been enacted in a number of states to date, and in 
recent years have been considered by several other state legislatures. Cleaning product ingredient disclosure legislation has 
been introduced in the U.S. Congress in each of the past few years but has not passed, and several states are considering 
further regulations in this area. In 2017, California passed the Cleaning Product Right to Know Act of 2017, that required 
ingredient transparency on-line and on-label by 2020 and 2021, respectively. New York has proposed similar ingredient 
disclosure regulation. The U.S. Government is monitoring “green chemistry” initiatives through a variety of initiatives, including 
its “Design for the Environment” (“DfE”)/“Safer Choice” program. DfE/Safer Choice has three broad areas of work (recognition 
of safer products on a DfE/Safer Choice label, development of best practices for industrial processes and evaluation of safer 
chemicals), and we are involved in these to varying degrees. Our Global Institutional and Global Industrial cleaning products 
are subject to the regulations and may incur additional stay-in-market expenses associated with conducting the required 
alternatives analyses for chemicals of concern. To date, we generally have been able to comply with such legislative 
requirements by reformulation or labeling modifications. Such legislation has not had a material adverse effect on our 
consolidated results of operations, financial position or cash flows to date. 

TSCA: The nation’s primary chemicals management law, the Toxic Substances Control Act (“TSCA”), was updated for the first 
time in 40 years with the passage of the Frank R. Lautenberg Chemical Safety for the 21st Century Act (“LCSA”) in 2016. The 
LCSA modernizes the original 1976 legislation, aiming to establish greater public confidence in the safety of chemical 
substances in commerce and improve the U.S. Environmental Protection Agency’s (“EPA”) capability and authority to regulate 
existing and new chemical substances. For Ecolab, the TSCA changes mainly impact testing and submission costs for new 
and existing chemical substances in the United States. As a result of reform and administration changes, EPA reviews are 
resulting in the majority of new substances being regulated in some manner by the agency. Compliance with new requirements 
under TSCA are similar to the costs associated with REACH in the European Union, which is discussed below. 

REACH: The European Union has enacted a regulatory framework for the Registration, Evaluation and Authorization of 
Chemicals (“REACH”), which aims to manage chemical safety risks. REACH established a European Chemicals Agency 
(“ECHA”) in Helsinki, Finland, which is responsible for evaluating data to determine hazards and risks and to manage this 
program for authorizing chemicals for sale and distribution in Europe. We met all REACH registration requirements. To help 
manage this program, we have been simplifying our product lines and working with chemical suppliers to comply with 
registration requirements. In addition, Korea, Taiwan, Turkey, India, Chile and Colombia and other countries have implemented 
or are implementing similar requirements. In addition, the European Green Deal will include the revision of chemical 

10 

management regulation to achieve a circular economy and toxic-free environment (Chemical Strategy for Sustainability) which 
may impact sales in Ecolab’s raw material portfolio. Potential costs to us are not yet fully quantifiable but are not expected to 
have a material adverse effect on our consolidated results of operations or cash flows in any one reporting period or on our 
financial position. 

GHS: In 2003, the United Nations adopted a standard on hazard communication and labeling of chemical products known as 
the Globally Harmonized System of Classification and Labeling of Chemicals (“GHS”). GHS is designed to facilitate 
international trade and increase safe handling and use of hazardous chemicals through a worldwide system that classifies 
chemicals based on their intrinsic hazards and communicates information about those hazards through standardized product 
labels and safety data sheets (“SDSs”). As of 2023, most countries in which we operate have adopted or are expected to adopt 
GHS-related legislation. The primary cost of compliance revolves around reclassifying products and revising SDSs and product 
labels. We have met applicable deadlines and are working toward a phased-in approach to mitigate the costs of GHS 
implementation in remaining countries (e.g., Peru, Chile, India). Potential costs to us are not expected to have a material 
adverse effect on our consolidated results of operations or cash flows in any one reporting period or on our financial position. 

Pesticide and Biocide Legislation: Various international, federal and state environmental laws and regulations govern the 
manufacture and/or use of pesticides. We manufacture and sell certain disinfecting, sanitizing and material preservation 
products that kill or reduce microorganisms (bacteria, viruses, fungi) on hard environmental surfaces, in process fluids and on 
certain food products. Such products constitute “pesticides” or “antimicrobial pesticides” under the current definitions of the 
Federal Insecticide, Fungicide, and Rodenticide Act (“FIFRA”), as amended by the Food Quality Protection Act of 1996, the 
principal federal statute governing the manufacture, labeling, handling and use of pesticides. We maintain several hundred 
product registrations with the U.S. Environmental Protection Agency (“EPA”). Registration entails the necessity to meet certain 
efficacy, toxicity and labeling requirements and to pay on-going registration fees. In addition, each state in which these 
products are sold requires registration and payment of a fee. In general, the states impose no substantive requirements 
different from those required by FIFRA. However, California and certain other states have adopted additional regulatory 
programs, and California imposes a tax on total pesticide sales in that state. While the cost of complying with rules as to 
pesticides has not had a material adverse effect on our consolidated results of operations, financial condition, or cash flows to 
date, the costs and delays in receiving necessary approvals for these products continue to increase. Total fees paid to the EPA 
and the states to obtain or maintain pesticide registrations are not expected to significantly affect our consolidated results of 
operations or cash flows in any one reporting period or our financial position. 

In Europe, the Biocidal Products Regulation established a program to evaluate and authorize marketing of biocidal active 
substances and products. We are working with suppliers and industry groups to manage these requirements and have met all 
relevant deadlines of the program by the timely submission of dossiers for active substances and biocide products. Anticipated 
registration costs, which will be incurred through the multi-year phase-in period, will be significant; however, these costs are not 
expected to significantly affect our consolidated results of operations or cash flows in any one reporting period or our financial 
position. The same is true for emerging biocide regulations in Asia. 

In addition, Pest Elimination applies restricted-use pesticides that it generally purchases from third parties. That business must 
comply with certain standards pertaining to the use of such pesticides and to the licensing of employees who apply such 
pesticides. Such regulations are enforced primarily by the states or local jurisdictions in conformity with federal regulations. We 
have not experienced material difficulties in complying with these requirements.  

FDA Antimicrobial Product Requirements: Various laws and regulations have been enacted by federal, state, local and 
foreign jurisdictions regulating certain products manufactured and sold by us for controlling microbial growth on humans, 
animals and foods. In the United States, these requirements generally are administered by the U.S. Food and Drug 
Administration ("FDA"). However, the U.S. Department of Agriculture and EPA also may share in regulatory jurisdiction of 
antimicrobials applied to food. The FDA codifies regulations for these product categories in order to ensure product quality, 
safety and effectiveness. The FDA also has been expanding requirements applicable to such products, including proposing 
regulations for over-the-counter antiseptic drug products, which may impose additional requirements associated with 
antimicrobial hand care products and associated costs when finalized by the FDA. FDA regulations associated with the Food 
Safety Modernization Act may impose additional requirements related to safety product lines. To date, such requirements have 
not had a material adverse effect on our consolidated results of operations, financial position or cash flows. 

Medical Device and Drug Product Requirements: As a manufacturer, distributor and marketer of medical devices and 
human drugs, we also are subject to regulation by the FDA and corresponding regulatory agencies of the state, local and 
foreign governments in which we sell our products. These regulations govern the development, testing, manufacturing, 
packaging, labeling, distribution and marketing of medical devices and medicinal products, including Advanced Pharmaceutical 
Ingredients (“API”), excipients and resins for biopharmaceutical processing. We also are required to register with the FDA as a 
medical device and drug manufacturer, comply with post-market reporting (e.g., Adverse Event Reporting, MDR and Recall) 
requirements, and to comply with the FDA’s current Good Manufacturing Practices and Quality System Regulations which 
require that we have a quality system for the design and production of our products intended for commercial distribution in the 
United States and satisfy recordkeeping requirements with respect to our manufacturing, testing and control activities. 
Countries in the European Union require that certain products being sold within their jurisdictions obtain a “CE mark,” an 
international symbol of adherence to quality assurance standards, and be manufactured in compliance with certain 
requirements (e.g., Medical Device Directive 93/42/EEC, Medical Device Regulation (EU) 2017/745 (“MDR”), and ISO 13485). 
We have CE mark approval to sell various medical device and medicinal products in Europe. Implementation of the MDR will 
require additional certifications and investments, including system, product and process upgrades. Our other international non-

11 

European operations also are subject to government regulation and country-specific rules and regulations. Regulators at the 
federal, state and local level have imposed, are currently considering and are expected to continue to impose regulations on 
medical devices and drug products. No prediction can be made of the potential effect of any such future regulations, and there 
can be no assurance that future legislation or regulations will not increase the costs of our products or prohibit the sale or use 
of certain products. 

Equipment: Ecolab’s products are dispensed by equipment that is subject to state and local regulatory requirements, as well 
as being subject to UL, NSF, and other approval requirements. For certain digitally connected product offerings, Federal 
Communication Commission (“FCC”) and corresponding international requirements are applicable. We have both dedicated 
manufacturing facilities and third-party production of our equipment. We are developing processes to monitor and manage 
changing regulatory regimes and assist with equipment systems compliance. To date, such requirements have not had a 
material adverse effect on our consolidated results of operations, financial position or cash flows. 

Other Environmental Legislation: Our manufacturing plants are subject to federal, state, local or foreign jurisdiction laws and 
regulations relating to discharge of hazardous substances into the environment and to the transportation, handling and 
disposal of such substances. The primary federal statutes that apply to our activities in the United States are the Clean Air Act, 
the Clean Water Act and the Resource Conservation and Recovery Act. We are also subject to the Superfund Amendments 
and Reauthorization Act of 1986, which imposes certain reporting requirements as to emissions of hazardous substances into 
the air, land and water. The products we produce and distribute into Europe are also subject to directives governing electrical 
waste (WEEE Directive 2012/19/EU) and restrictive substances (RoHS Directive 2011/65/EU). Similar legal requirements apply 
to Ecolab’s facilities globally. We make capital investments and expenditures to comply with environmental laws and 
regulations, to promote employee safety and to carry out our announced environmental sustainability principles. To date, such 
expenditures have not had a significant adverse effect on our consolidated results of operations, financial position or cash 
flows. Our capital expenditures for environmental, health and safety projects worldwide were approximately $46 million in 2023, 
$35 million in 2022 and $28 million in 2021. Approximately $51 million has been budgeted globally for projects in 2024.  

Climate Change: Various laws and regulations pertaining to climate change have been implemented or are being considered 
for implementation at the international, national, regional and state levels, particularly as they relate to the reduction of 
greenhouse gas (“GHG”) emissions. These include regulations passed by the State of California in 2023 relating to GHG 
emissions, climate-related risk, and emissions reduction claims, proposed regulations introduced by the SEC in March 2022 
relating to climate change disclosure, and the European Commission’s Corporate Sustainability Reporting Directive, which 
came into force on January 2024 and applies to both EU and certain non-EU companies with a phased introduction. We are or 
may become subject to many of these laws. We continue to monitor the development and implementation of such laws and 
regulations, and are preemptively evaluating and, where appropriate, including reporting and disclosure obligations.  

Ecolab recognizes that climate change poses potential risks to and creates potential opportunities for our organization. 
Climate-related risks are assessed within our Enterprise Risk Management process and Annual Business Significance Risks 
Assessment, which is aligned with recommendations of the Financial Stability Board (“FSB”) Task Force on Climate-related 
Financial Disclosures (“TCFD”). We report TCFD disclosures in our annual CDP Climate report located on our website. Ecolab 
continues to focus on climate-related risks since our first TCFD-aligned climate risk assessment conducted in 2021 – we plan 
to regularly review the results of our analysis and consider adaptation and management plans for any relevant climate change 
risks and to further benefit from identified opportunities for customer impact. Ecolab also evaluates potential water-related risks 
in our direct operations that may be exacerbated by climate change and discloses the results in our Corporate Responsibility 
Report. We plan to explore additional analyses of potential nature-related risks that may link to climate- and water-related risks 
in the future, aligned with the emerging recommendations of the Task Force on Nature-Related Financial Disclosures (“TNFD”). 

As a matter of corporate policy, we support a balanced approach to reducing GHG emissions while sustaining economic 
growth. To further our climate commitment, in 2019 we announced new goals to reduce our operational GHG emissions by half 
by 2030 and achieve net zero by 2050, in alignment with the United Nations Global Compact’s Business Ambition for 1.5⁰C. In 
2020, we further committed to attempt to move to 100% renewable energy by 2030 and set a science-based target (“SBT”) 
addressing our Scope 1, 2 and 3 GHG emissions, and in 2022 we committed to submitting our net zero target to the Science 
Based Targets initiative (“SBTi”) for formal validation. With the increasing complexity of supply chain emissions, in 2023 we 
decided to develop a revised Scope 3 target that prioritizes absolute emissions reduction. We plan to continue our supplier 
engagement practices to advance climate action outside of our operations. We submitted our new Scope 3 target along with 
our net zero target in early 2024 for validation by the SBTi. Our near-term SBT continues to target reduction of absolute Scope 
1 and 2 emissions by 50% by 2030 from a 2018 base year and we report our progress in our annual Corporate Responsibility 
Report. 

In 2022, we invested $65 million in capital and $6 million in operating expenses to implement continuous improvement projects 
positively impacting our environmental performance. In 2022, we completed process improvement projects that reduced total 
energy consumption by almost 21.4 billion BTUs, emissions by 11,000 metric tons CO2e and 12.7 million gallons (~48,000 
cubic meters) of water savings. The reduction in energy consumption is calculated using a combination of direct measurements 
and estimations using best-practice methodologies. The scope of reduction in GHG emissions consumption data is an 
estimated annual impact and includes both Scope 1 and 2 emissions. Water data from meter readings and utilities reports is 
used to quantify the water savings with 2018 as our baseline year. 

12 

In addition to managing our operational and supply chain sustainability performance, we help our customers in more than 170 
countries to reduce their energy and GHG emissions through our high-efficiency solutions in cleaning and sanitation, water, 
paper, and energy services. Showcasing our global team’s dedication to helping our customers thrive and make a positive 
impact in the world, we have set a 2030 goal to help our customers reduce their GHG emissions by 6.0 million metric tons. 
Ecolab recognizes the climate-water nexus. As part of our 2030 Impact Goals, we have planned to restore greater than 50% of 
our water withdrawal and achieve Alliance for Water Stewardship Standard certification in high-risk watersheds. In addition, we 
aim to reduce net water withdrawals by 40% per unit of production across our enterprise. We also magnify our impact through 
the water-saving solutions we deliver to our customers and have set a goal to help our customers conserve more than 300 
billion gallons of water annually by 2030. 

The science of sustainability is an evolving one. For a discussion of the factors that may cause our sustainability initiatives, 
goals and targets to differ from those expressed above, see Item 1A of this Form 10-K, entitled “Risk Factors.” 

Environmental Remediation and Proceedings: Along with numerous other potentially responsible parties (“PRP”), we are 
currently involved with waste disposal site clean-up activities imposed by the federal Comprehensive Environmental Response, 
Compensation and Liability Act (“CERCLA”) or state equivalents at 16 sites in the United States. Additionally, we have similar 
liability at six sites outside the United States. In general, under CERCLA, we and each other PRP that actually contributed 
hazardous substances to a Superfund site are jointly and severally liable for the costs associated with cleaning up the site. 
Customarily, the PRPs will work with the EPA to agree and implement a plan for site remediation.  

Based on an analysis of our experience with such environmental proceedings, our estimated share of all hazardous materials 
deposited on the sites referred to in the preceding paragraph, and our estimate of the contribution to be made by other PRPs 
which we believe have the financial ability to pay their shares, we have accrued our best estimate of our probable future costs 
relating to such known sites. In establishing accruals, potential insurance reimbursements are not included. The accrual is not 
discounted. It is not feasible to predict when the amounts accrued will be paid due to the uncertainties inherent in the 
environmental remediation and associated regulatory processes. 

We have also been named as a defendant in a number of lawsuits alleging personal injury due to exposure to hazardous 
substances, including multi-party lawsuits alleging personal injury in connection with our products and services. While we do 
not believe that any of these suits will be material to us based upon present information, there can be no assurance that these 
environmental matters could not have, either individually or in the aggregate, a material adverse effect on our consolidated 
results of operations, financial position or cash flows. 

We have also been named as a defendant in lawsuits where our products have not caused injuries, but the claimants wish to 
be monitored for potential future injuries. We cannot predict with certainty the outcome of any such tort claims or the 
involvement we or our products might have in such matters in the future, and there can be no assurance that the discovery of 
previously unknown conditions will not require significant expenditures. In each of these chemical exposure cases, our 
insurance carriers have accepted the claims on our behalf (with or without reservation) and our financial exposure should be 
limited to the amount of our deductible; however, we cannot predict the number of claims that we may have to defend in the 
future and we may not be able to continue to maintain such insurance. 

Our worldwide net expenditures for contamination remediation were approximately $0.3 million in 2023, $1.4 million in 2022 and 
$0.5 million in 2021. Our worldwide accruals at December 31, 2023 for probable future remediation expenditures, excluding 
potential insurance reimbursements, totaled approximately $9.3 million. We review our exposure for contamination remediation 
costs periodically and our accruals are adjusted as considered appropriate. While the final resolution of these issues could result in 
costs below or above current accruals and, therefore, have an impact on our consolidated financial results in a future reporting 
period, we believe the ultimate resolution of these matters will not have a material effect on our consolidated results of operations, 
financial position or cash flows.

Item 1A. Risk Factors. 

The following are important factors which could affect our financial performance and could cause our actual results for future periods to 
differ materially from our anticipated results or other expectations, including those expressed in any forward-looking statements made in 
this Form 10-K. See the section entitled “Forward-Looking Statements” set forth above.  

We may also refer to this disclosure to identify factors that may cause results to differ materially from those expressed in other forward-
looking statements including those made in oral presentations, including telephone conferences and/or webcasts open to the public.  

Economic & Operational Risks 

Our results are impacted by general worldwide economic factors.  

Over the past year, global interest rates aimed at curbing inflation, as well as implications of geopolitical situations in Europe, the Middle 
East and China, have resulted in economic and demand uncertainty. Previously, the COVID pandemic, geopolitical instability and other 
global events have resulted in supply chain challenges, inflation, high interest rates, foreign currency exchange volatility, and volatility in 
global capital markets, which have affected our business and could have a material adverse impact on our business in the future. 
Countries such as Argentina and Turkey have experienced economic upheaval and similar upheaval in other countries with Ecolab 
operations could have a material adverse impact on our consolidated results of operations, financial position and cash flows by 
negatively impacting economic activity, including in our key end-markets, and by further weakening the local currency versus the U.S. 
dollar, resulting in reduced sales and earnings from our foreign operations, which are generated in the local currency, and then 
translated to U.S. dollars. 

Our results depend upon the continued vitality of the markets we serve. 

Economic downturns, and in particular downturns in our larger markets including the foodservice, hospitality, travel, health care, food 
processing, refining, pulp and paper, mining and steel industries, can adversely impact our customers, and we may find it difficult to 
restore margins by maintaining pricing due to easing inflation from slowing economic growth. Recently, the war and energy crisis in 
Europe have resulted in a more challenging macroeconomic environment with significantly impacted costs and demand. Previously, the 
COVID-19 pandemic negatively impacted the demand for our products and services provided to customers in the full-service restaurant, 
hospitality, lodging and entertainment industries. In prior years, a weaker global economic environment has also negatively impacted 
certain of our other end-markets. During these periods of weaker economic activity, our customers and potential customers may reduce 
or discontinue their volume of purchases of cleaning and sanitizing products and water treatment and process chemicals, which has had, 
and may continue to have, a material adverse effect on our business, financial condition, results of operation or cash flows. 

Our significant non-U.S. operations expose us to global economic, political and legal risks that could impact our profitability. 

We have significant operations outside the United States, including joint ventures and other alliances. We conduct business in more than 
170 countries and, in 2023, approximately 47% of our net sales originated outside the United States. There are inherent risks in our 
international operations, including:  





exchange controls and currency restrictions;
currency fluctuations and devaluations;
tariffs and trade barriers;
export duties and quotas;
changes in the availability and pricing of raw materials, energy and utilities;
changes in local economic conditions;
changes in laws and regulations, including the imposition of economic or trade sanctions affecting international commercial
transactions;
difficulties in managing international operations and the burden of complying with international and foreign laws;
requirements to include local ownership or management in our business;
economic and business objectives that differ from those of our joint venture partners;
exposure to possible expropriation, nationalization or other government actions;
restrictions on our ability to repatriate dividends from our subsidiaries;
unsettled political conditions, military action, civil unrest, acts of terrorism, force majeure, war or other armed conflict,
including the Russian invasion of Ukraine, the Israel-Hamas conflict and other hostilities in the Middle East; and
countries whose governments have been hostile to U.S.-based businesses.

Following Russia’s invasion of Ukraine and the United States’ and other countries’ sanctions against Russia, we have limited our Russian 
business to operations that are essential to life, providing minimal support for our healthcare, life sciences, food and beverage and 
certain water businesses, and we may further narrow our presence in Russia depending on developments in the conflict or otherwise. 
While our operations in Russia and areas experiencing conflict are not material to our business and financial results, the escalation of 
these conflicts may also heighten many other risks disclosed in our report on Form 10-K, any of which could materially and adversely 
affect our business and financial results. Such risks include, but are not limited to, adverse effects on macroeconomic conditions, 
including increased inflation, constraints on the availability of commodities, supply chain disruption and decreased business spending; 
disruptions to our or our business partners’ global technology infrastructure, including through cyber-attack or cyber-intrusion; adverse 
changes in international trade policies and relations; claims, litigation and regulatory enforcement; our ability to implement and execute 

16 

our business strategy; terrorist activities; our exposure to foreign currency fluctuations; reputational risk; and constraints, volatility, or 
disruption in the capital markets. 

Additionally, changes in U.S. or foreign government policy on international trade, including the imposition or continuation of tariffs, could 
materially and adversely affect our business. In 2018, the U.S. imposed tariffs on certain imports from China and other countries, 
resulting in retaliatory tariffs by China and other countries. While the U.S. and China signed a Phase One trade agreement in January 
2020, which included the suspension and rollback of tariffs, the CHIPS and Science Act of 2022 with objectives including countering 
China’s technical ambitions was signed into law in August 2022. Any new tariffs or policies imposed by the U.S., China or other countries 
or any additional retaliatory measures by any of these countries, could increase our costs, reduce our sales and earnings or otherwise 
have an adverse effect on our operations. 

Further, our operations outside the United States require us to comply with a number of United States and non-U.S. laws and regulations, 
including anti-corruption laws such as the United States Foreign Corrupt Practices Act and the United Kingdom Bribery Act, as well as 
U.S. and non-U.S. economic sanctions regulations. We have internal policies and procedures relating to such laws and regulations; 
however, there is risk that such policies and procedures will not always protect us from the misconduct or reckless acts of employees or 
representatives, particularly in the case of recently acquired operations that may not have significant training in applicable compliance 
policies and procedures. Violations of such laws and regulations could result in disruptive investigations, significant fines and sanctions, 
which could have a material adverse effect on our consolidated results of operations, financial position or cash flows. 

Also, because of uncertainties regarding the interpretation and application of laws and regulations and the enforceability of intellectual 
property and contract rights, we face risks in some countries that our intellectual property rights and contract rights would not be enforced 
by local governments. We are also periodically faced with the risk of economic uncertainty, which has impacted our business in some 
countries. Other risks in international business also include difficulties in staffing and managing local operations, including managing 
credit risk to local customers and distributors. 

Our overall success as a global business depends, in part, upon our ability to succeed in differing economic, social, legal and political 
conditions. We may not continue to succeed in developing and implementing policies and strategies that are effective in each location 
where we do business, which could have a material adverse effect on our consolidated results of operations, financial position or cash 
flows. 

We may experience business disruption if we fail to execute organizational change and management transitions. 

Our continued success will depend on the efforts and abilities of our executive officers and certain other key employees, particularly 
those with sales and sales management responsibilities, to drive business growth, development and profitability. Our operations could be 
materially and adversely affected if for any reason we are unable to successfully execute organizational change and management 
transitions at leadership levels. 

We are subject to information technology system failures, network disruptions and breaches in data security. 

We rely to a large extent upon information technology systems and infrastructure to operate our business. The size and complexity of our 
information technology systems and those of strategic vendors make them vulnerable to failure, malicious intrusion and random attack. 
Acquisitions have resulted in further de-centralization of systems and additional complexity in our systems infrastructure. Likewise, data 
security breaches by employees or others with permitted access to our systems or to the systems of strategic vendors pose a risk that 
sensitive data may be exposed to unauthorized persons or to the public. Geopolitical tensions or conflicts, such as Russia’s invasion of 
Ukraine, may further heighten the risk of cybersecurity attacks. While we have continually matured our security program and capabilities 
and have had no material incidents to date, cyber threats continue to evolve and there can be no assurance that our efforts will prevent 
cybersecurity attacks or breaches in our systems or in the systems of strategic vendors, including cloud providers, that could cause 
reputational damage, business disruption or legal and regulatory costs; could result in third-party claims; could result in compromise or 
misappropriation of our intellectual property, trade secrets or sensitive information; or could otherwise materially adversely affect our 
business, including our business strategy, results of operations, or financial condition. Certain of our customer offerings include digital 
components, such as remote monitoring of certain customer operations. A breach of those remote monitoring systems could expose 
customer data giving rise to potential third-party claims and reputational damage. There may be other related challenges and risks as we 
complete implementation of our ERP system upgrade. 

Our results could be materially and adversely affected by difficulties in securing the supply of certain raw materials or by 
fluctuations in the cost of raw materials. 

The prices of raw materials used in our business fluctuate, and in recent years we have experienced periods of significant increased raw 
material costs. Changes in raw material prices, unavailability of adequate and reasonably priced raw materials or substitutes for those 
raw materials, or the inability to obtain or renew supply agreements on favorable terms has materially and adversely affected our 
business and can in the future materially and adversely affect our consolidated results of operations, financial position or cash flows. In 
addition, volatility and disruption in economic activity and conditions could disrupt or delay the performance of our suppliers and thus 
impact our ability to obtain raw materials at favorable prices or on favorable terms, which may materially and adversely affect our 
business. 

17 

 
 
 
 
 
 
 
 
 
 
 
Severe public health outbreaks not limited to COVID-19 may adversely impact our business. 

The COVID-19 pandemic had a rapid and significant negative impact on the global economy, including a significant downturn in the 
foodservice, hospitality and travel industries. Measures taken to alleviate the pandemic (such as stay-at-home orders and other 
responsive measures) significantly impacted our restaurant and hospitality customers and negatively affected demand for our products 
and services in these segments, resulting in a material adverse effect on our business and results of operations. Besides the COVID-19 
pandemic, the United States and other countries have experienced, and may experience in the future, public health outbreaks such as 
Zika virus, Avian Flu, SARS and H1N1 influenza. A prolonged occurrence of a contagious disease such as these could result in a 
significant downturn in the foodservice, hospitality and travel industries and also may result in health or other government authorities 
imposing restrictions on travel further impacting our end markets. Any of these events could result in a significant drop in demand for 
some of our products and services and materially and adversely affect our business. 

Strategic Risks 

If we are unsuccessful in integrating acquisitions our business could be materially and adversely affected. 

We seek to acquire complementary businesses as part of our long-term strategy. There can be no assurance that we will find attractive 
acquisition candidates or succeed at effectively managing the integration of acquired businesses, including Purolite, which operates in 
the highly regulated life sciences, pharma and biopharma industries and has extensive international operations which complicate 
integration execution. If the underlying business performance of such acquired businesses deteriorates, the expected synergies from 
such transactions do not materialize or we fail to successfully integrate new businesses into our existing businesses, our consolidated 
results of operations, financial position or cash flows could be materially and adversely affected. 

If we are unsuccessful in executing on key business initiatives, our business could be materially and adversely affected. 

We continue to execute key business initiatives as part of our ongoing efforts to improve our efficiency and returns. In particular, we are 
making supply chain investments to secure supply and add new capacity in our Life Sciences business. Additionally, we are continuing 
implementation of our ERP system upgrades, which are expected to continue in phases over the next several years. These upgrades, 
which include sales, supply chain and certain finance functions, are expected to improve the efficiency of certain financial and related 
transactional processes. These upgrades involve complex business process design and a failure of certain of these processes could 
result in business disruption. We are also undertaking the Combined Program focused on optimizing the cost structure of our business in 
Europe and our Institutional and Healthcare businesses, which is discussed along with other restructuring activities under Note 3 of this 
Form 10-K. If the projects in which we are investing or the initiatives which we are pursuing are not successfully executed, our 
consolidated results of operations, financial position or cash flows could materially and adversely be affected. 

Our growth depends upon our ability to compete successfully with respect to value, innovation and customer support.  

We have numerous global, national, regional and local competitors. Our ability to compete depends in part on providing high quality and 
high value-added products, technology and service. We must also continue to identify, develop and commercialize innovative, profitable 
and high value-added products for niche applications and commercial digital applications. We have made significant investments in 
commercial digital product offerings, and our culture and expertise must continue to evolve to develop, support and profitably deploy 
commercial digital offerings, which are becoming an increasingly important part of our business. There can be no assurance that we will 
be able to accomplish our technology development goals or that technological developments by our competitors, including in the area of 
artificial intelligence, will not place certain of our products, technology or services at a competitive disadvantage in the future. In addition, 
certain of the new products that we have under development will be offered in markets in which we do not currently compete, and there 
can be no assurance that we will be able to compete successfully in those new markets. If we fail to introduce new technologies or 
commercialize our digital offerings on a timely and profitable basis, we may lose market share and our consolidated results of operations, 
financial position or cash flows could be materially and adversely affected. 

Consolidation of our customers and vendors could materially and adversely affect our results. 

Customers and vendors in the foodservice, hospitality, travel, healthcare, energy, life sciences, food processing and pulp and paper 
industries, as well as other industries we serve, have consolidated in recent years and that trend may continue. This consolidation could 
have a material adverse impact on our ability to retain customers and on our pricing, margins and consolidated results of operations. 

We enter into multi-year contracts with customers that could impact our results. 

Our multi-year contracts with some of our customers include terms affecting our pricing flexibility. There can be no assurance that these 
restraints will not have a material adverse impact on our margins and consolidated results of operations. 

Legal, Regulatory & Compliance Risks 

Our business depends on our ability to comply with laws and governmental regulations and meet our contractual commitments 
and failure to do so could materially and adversely impact our business; and we may be materially and adversely affected by 
changes in laws and regulations. 

Our business is subject to numerous laws and regulations relating to the environment, including evolving climate change standards, and 
to the manufacture, storage, distribution, sale and use of our products as well as to the conduct of our business generally, including 

18 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
employment and labor laws and anti-corruption laws. Furthermore, increasing public and governmental awareness and concern 
regarding the effects of climate change has led to significant legislative and regulatory efforts to limit greenhouse gas emissions and will 
likely result in further environmental and climate change laws and regulations. Compliance with these laws and regulations exposes us to 
potential financial liability and increases our operating costs. A violation of these laws and regulations could expose us to financial liability 
that may have a material adverse effect on our results of operations and cash flows. Regulation of our products and operations continues 
to increase with more stringent standards, causing increased costs of operations and potential for liability if a violation occurs. The 
potential cost to us relating to environmental and product registration laws and regulations is uncertain due to factors such as the 
unknown magnitude and type of possible contamination and clean-up costs, the complexity and evolving nature of laws and regulations, 
and the timing and expense of compliance. Changes to current laws (including tax laws), regulations and policies could impose new 
restrictions, costs or prohibitions on our current practices which would have a material adverse effect on our consolidated results of 
operations, financial position or cash flows. Changes to labor and employment laws and regulations, as well as related rulings by courts 
and administrative bodies, could materially and adversely affect our operations and expose us to potential financial liability. 

Defense of litigation, particularly certain types of actions such as antitrust, patent infringement, personal injury, product liability, breach of 
contract, wage hour and class action lawsuits, can be costly and time consuming even if ultimately successful, and if not successful could 
have a material adverse effect on our consolidated results of operations, financial position or cash flows. 

A chemical spill or release could materially and adversely impact our business.  

As a manufacturer and supplier of chemical products, there is a potential for chemicals to be accidentally spilled, released or discharged, 
either in liquid or gaseous form, during production, transportation, storage or use. Such a release could result in environmental 
contamination as well as a human or animal health hazard. Accordingly, such a release could have a material adverse effect on our 
consolidated results of operations, financial position or cash flows. 

Potential indemnification liabilities pursuant to the separation and split-off of our Upstream Energy business could materially 
and adversely affect our business and financial statements. 

With respect to the separation and subsequent split-off of our Upstream Energy business, we entered into a separation and distribution 
agreement with ChampionX Holding Inc. and ChampionX Corporation (f/k/a Apergy Corporation and taken together with ChampionX 
Holding Inc., “ChampionX”) as well as certain other agreements to govern the separation and related transactions and our relationship 
with ChampionX going forward. These agreements provide for specific indemnity and certain other obligations of each party and could 
lead to disputes between ChampionX and us. If we are required to indemnify ChampionX under the circumstances set forth in these 
agreements, we may be subject to substantial related liabilities. In addition, with respect to the liabilities for which ChampionX has agreed 
to indemnify us under these agreements, there can be no assurance that the indemnity rights we have against ChampionX will be 
sufficient to protect us against the full amount of such liabilities, or that ChampionX will be able to fully satisfy its indemnification 
obligations. Each of these risks could negatively affect our business and our consolidated results of operations, financial position or cash 
flows could be materially and adversely affected. 

Extraordinary events may significantly impact our business.  

The occurrence of (a) litigation or claims, (b) the loss or insolvency of a major customer or distributor, (c) repeated or prolonged federal 
government shutdowns or similar events, (d) war (including acts of terrorism or hostilities which impact our markets), (e) natural or 
manmade disasters, (f) water shortages or (g) severe weather conditions affecting our operations or the energy, foodservice, hospitality 
and travel industries may have a material adverse effect on our business. 

While we have a diverse customer base and no customer or distributor constitutes 10 percent or more of our consolidated revenues, we 
do have customers and independent, third-party distributors, the loss of which could have a material adverse effect on our consolidated 
results of operations or cash flows for the affected earnings periods.  

Government shutdowns can have a material adverse effect on our consolidated results of operations or cash flows by disrupting or 
delaying new product launches, renewals of registrations for existing products and receipt of import or export licenses for raw materials or 
products. 

War (including acts of terrorism or hostilities), natural or manmade disasters, water shortages or severe weather conditions, including the 
effects of climate change, affecting the energy, foodservice, hospitality, travel, health care, food processing, pulp and paper, mining, steel 
and other industries can cause a downturn in the business of our customers, which in turn can have a material adverse effect on our 
consolidated results of operations, financial position or cash flows. In particular, the U.S. Gulf Coast is a region with significant refining, 
petrochemicals and chemicals operations which provide us raw materials, as well as being an important customer base for our Water 
operating segment. Hurricanes or other severe weather events impacting the Gulf Coast, such as the winter freeze in Texas and the Gulf 
Coast in February 2021, can materially and adversely affect our ability to obtain raw materials at reasonable cost, or at all, and could 
adversely affect our business with our customers in the region. 

Our commitments, goals, targets, objectives and initiatives related to sustainability, and our public statements and disclosures 
regarding them, expose us to numerous risks. 

We have developed, and will continue to establish, goals, targets, and other objectives related to sustainability matters, including our 
sustainability goals in alignment with the United Nations Global Compact’s Business Ambition for 1.5⁰C and our commitments to science-
based targets addressing Scope 1, 2 and 3 GHG emissions, discussed in Item 1 of Part I of this Form 10-K, entitled “Business.” 

19 

Achieving these goals and commitments will require evolving our business, capital investment and the development of technology that 
might not currently exist. We might incur additional expense or be required to recognize impairment charges in connection with our 
efforts. These commitments, goals, targets and other objectives reflect our current plans and there is no guarantee that they will be 
achieved. Our efforts to research, establish, accomplish, and accurately report on these commitments, goals, targets, and objectives 
expose us to operational, reputational, financial, legal, and other risks. Our ability to achieve any stated commitment, goal, target, or 
objective is subject to factors and conditions, many of which are outside of our control, including the pace of changes in technology, the 
availability of requisite financing, and the availability of suppliers that can meet our sustainability and other standards. 

Our business may face increased scrutiny from the investment community, other stakeholders, regulators, and the media related to our 
sustainability activities, including our commitments, goals, targets, and objectives, and our methodologies and timelines for pursuing 
them. If our sustainability practices do not meet investor or other stakeholder expectations and standards, which continue to evolve, our 
reputation, our ability to attract or retain employees, and our attractiveness as an investment, business partner, or as an acquiror could 
be negatively impacted. Similarly, our failure or perceived failure to pursue or fulfill our commitments, goals, targets, and objectives, to 
comply with ethical, environmental, or other standards, regulations, or expectations, or to satisfy reporting standards with respect to these 
matters, within the timelines we announce, or at all, could have operational, reputational, financial and legal impacts. 

Financial Risks 

If the separation and split-off of our Upstream Energy business or certain internal transactions undertaken in anticipation of the 
divestiture are determined to be taxable in whole or in part, we and our stockholders may incur significant tax liabilities. 

In connection with the separation and split-off of our Upstream Energy business that was consummated on June 3, 2020, we obtained 
opinions of outside tax counsel that the related merger and exchange offer will qualify as tax-free transactions to us and our stockholders, 
except to the extent that cash was paid to Ecolab stockholders in lieu of fractional shares. We have not sought or obtained a ruling from 
the Internal Revenue Service (“IRS”) on the tax consequences of these transactions. An opinion of counsel is not binding on the IRS or 
the courts, which may disagree with the opinion. Even if the merger and exchange offer otherwise qualified as tax-free transactions, they 
may become taxable to us if certain events occur that affect either Ecolab or ChampionX Corporation. While ChampionX Corporation has 
agreed not to take certain actions that could cause the transactions not to qualify as tax-free transactions and is generally obligated to 
indemnify us against any tax consequences if it breaches this agreement, the potential tax liabilities could have a material adverse effect 
on us if we were not entitled to indemnification or if the indemnification obligations were not fulfilled. If the merger or exchange offer were 
determined to be taxable, we could be subject to a substantial tax liability, and each U.S. holder of our common stock who participated in 
the exchange offer could be treated as exchanging the Ecolab shares surrendered for ChampionX Corporation shares in a taxable 
transaction. 

Changes in tax laws and unanticipated tax liabilities could materially and adversely affect the taxes we pay and our profitability. 

We are subject to income and other taxes in the United States and foreign jurisdictions, and our operations, plans and results are 
affected by tax and other initiatives around the world. We are also impacted by actions taken to tax-related matters by associations such 
as the Organization for Economic Co-operation and Development (“OECD”), which represents a coalition of member countries, and the 
European Commission which influence tax policies in countries where we operate. In particular, the OECD is coordinating negotiations 
among more than 140 jurisdictions with the goal of achieving consensus on various substantial changes to the international tax 
framework, including a 15% global minimum taxation regime (“Pillar Two”). Pillar Two takes effect in several jurisdictions in which we 
operate starting in 2024 and will increase the burden and costs of our tax compliance. The company continues to monitor these 
legislative developments, but based on information available does not anticipate material impacts to the 2024 financial statements. In 
addition, we are impacted by settlements of pending or any future adjustments proposed by the IRS or other taxing authorities in 
connection with our tax audits, all of which will depend on their timing, nature and scope. Increases in income tax rates, changes in 
income tax laws or unfavorable resolution of tax matters could have a material adverse impact on our financial results. 

Future events may impact our deferred tax position, including the utilization of foreign tax credits and undistributed earnings of 
international affiliates that are considered to be reinvested indefinitely.  

We evaluate the recoverability of deferred tax assets and the need for deferred tax liabilities based on available evidence. This process 
involves significant management judgment about assumptions that are subject to change from period to period based on changes in tax 
laws or variances between future projected operating performance and actual results. We are required to establish a valuation allowance 
for deferred tax assets if we determine, based on available evidence at the time the determination is made, that it is more likely than not 
that some portion or all of the deferred tax assets will not be realized. In making this determination, we evaluate all positive and negative 
evidence as of the end of each reporting period. Future adjustments (either increases or decreases), to the deferred tax asset valuation 
allowance are determined based upon changes in the expected realization of the net deferred tax assets. The realization of the deferred 
tax assets ultimately depends on the existence of sufficient taxable income in either the carry-back or carry-forward periods under the tax 
law. Due to significant estimates used to establish the valuation allowance and the potential for changes in facts and circumstances, it is 
reasonably possible that we will be required to record adjustments to the valuation allowance in future reporting periods. Changes to the 
valuation allowance or the amount of deferred tax liabilities could have a material adverse effect on our consolidated results of operations 
or financial position. Further, should we change our assertion regarding the permanent reinvestment of the undistributed earnings of 
international affiliates, a deferred tax liability may need to be established.

Our indebtedness may limit our operations and our use of our cash flow, and any failure to comply with the covenants that 
apply to our indebtedness could materially and adversely affect our liquidity and financial statements. 

As of December 31, 2023, we had approximately $8.2 billion in outstanding indebtedness, with approximately $1.5 billion in the form of 
floating rate debt. Our debt level and related debt service obligations may have negative consequences, including: 

 

 

 

 

requiring us to dedicate significant cash flow from operations to the payment of principal and interest on our debt, which 
reduces the funds we have available for other purposes such as acquisitions and capital investment;  

reducing our flexibility in planning for or reacting to changes in our business and market conditions; 

exposing us to interest rate risk since a portion of our debt obligations are at variable rates. For example, a one percentage 
point increase in the average interest rate on our floating rate debt at December 31, 2023 would increase future interest 
expense by approximately $15 million per year; and  

increasing our cost of funds and materially and adversely affecting our liquidity and access to the capital markets should we fail 
to maintain the credit ratings assigned to us by independent rating agencies.  

If we add new debt, the risks described above could increase. 

We incur significant expenses related to the amortization of intangible assets and may be required to report losses resulting 
from the impairment of goodwill or other assets recorded in connection with the Nalco and Purolite transactions and other 
acquisitions.  

We expect to continue to complete selected acquisitions and joint venture transactions in the future. In connection with acquisition and 
joint venture transactions, applicable accounting rules generally require the tangible and intangible assets of the acquired business to be 
recorded on the balance sheet of the acquiring company at their fair values. Intangible assets other than goodwill are required to be 
amortized over their estimated useful lives and this expense may be significant. Any excess in the purchase price paid by the acquiring 
company over the fair value of tangible and intangible assets of the acquired business is recorded as goodwill. If it is later determined 
that the anticipated future cash flows from the acquired business may be less than the carrying values of the assets and goodwill of the 
acquired business, the assets or goodwill may be deemed to be impaired. In this case, the acquiring company may be required under 
applicable accounting rules to write down the value of the assets or goodwill on its balance sheet to reflect the extent of the impairment. 
This write-down of assets or goodwill is generally recognized as a non-cash expense in the statement of operations of the acquiring 
company for the accounting period during which the write down occurs. As of December 31, 2023, we had goodwill of $8.1 billion which 
is maintained in various reporting units, including goodwill from the Nalco and Purolite transactions. If we determine that any of the assets 
or goodwill recorded in connection with the Nalco and Purolite transactions or any other prior or future acquisitions or joint venture 
transactions have become impaired, we will be required to record a loss resulting from the impairment. Impairment losses could be 
significant and could have a material adverse effect on our consolidated results of operations and financial position. 

Item 1B. Unresolved Staff Comments. 

We have no unresolved comments from the staff of the Securities and Exchange Commission. 

Item 1C. Cybersecurity. 

Since 2014, when the Ecolab Cybersecurity program was established, we have continuously matured our cybersecurity program to 
proactively address evolving cybersecurity trends and risks. Ecolab has an Information Security Steering Committee (“ISSC”), a cross-
functional team chaired by our Chief Information Security Officer (“CISO”) that is described more fully below. 

Senior management provides in-depth reviews of cybersecurity matters to the Board and the Audit Committee. Cybersecurity is also 
considered in the annual enterprise risk assessment presented to the Board by management as part of the Board’s oversight of our 
enterprise risk management (“ERM”) program. 

Ecolab’s cybersecurity policies, standards, processes, and practices are integrated into our ERM program and are based on recognized 
frameworks established by the National Institute of Standards and Technology (“NIST”) Cybersecurity Framework (“CSF”), the 
International Organization for Standardization and other applicable industry standards. We are formally assessed by an independent third 
party against NIST CSF and industry standards, including peer benchmarking. 

Risk Management and Strategy 

Cybersecurity presents strategic and operating risks and is an area of continued focus for our Board and management under its ERM 
program. Ecolab’s cybersecurity program addresses the following key areas: 

  Governance: As discussed in more detail under the heading “Cybersecurity Governance,” the Audit Committee and the Board 

of Directors provide oversight of cybersecurity risk management.





Technical Safeguards: We have implemented multi-layer controls designed to protect our information systems from
cybersecurity threats, including general, backup, recovery, resiliency, processing, access, change and risk controls. These
controls are evaluated by Ecolab’s cybersecurity team and enhanced through controls audits and assessments, internal
testing, and third-party cybersecurity threat intelligence.

Incident Response and Recovery Planning: We have established and maintain comprehensive cybersecurity incident
response and recovery plans that coordinate multidisciplinary internal teams and cybersecurity partners to assess, triage,
escalate, contain, mitigate, investigate, remediate, and recover from a potential cybersecurity incident. Through ongoing
communications with these teams, management monitors the incidents and reports incidents to the Audit Committee when
appropriate. Management is responsible for timely disclosure of cybersecurity incidents as required by law.

Third-Party Risk Management: We maintain a risk-based approach to identify, monitor, and manage third-party cybersecurity
risks associated with our use of third-party service providers who have access to our systems, data or are critical to our
continued business operations. Additionally, cybersecurity considerations affect the selection and oversight of our third-party
service providers. We require certain third-party vendors to agree to manage their cybersecurity risks in specified ways, and to
agree to be subject to cybersecurity audits, which we conduct as appropriate.

Education and Awareness: We provide training for personnel regarding cybersecurity trends and threats to equip them with
the knowledge to recognize and tools to report suspected cybersecurity threats. We also conduct simulations for employees
and contractors to enhance awareness and responsiveness to such possible threats. In addition, we send global cybersecurity
awareness communications to our personnel.

Assessment: We engage in the periodic assessment, testing and updating of our policies, standards, processes, and
practices that are designed to address cybersecurity threats and incidents. These efforts include a wide range of activities,
including audits, assessments, tabletop exercises, threat modeling, vulnerability testing and other exercises focused on
evaluating the effectiveness of our cybersecurity measures, and planning. We engage third parties to perform assessments on
our cybersecurity measures, including information security maturity assessments, audits and independent reviews of our
information security control environment and operating effectiveness. Additionally, we leverage third party cybersecurity rating
agency data to inform our assessment of risk. The results of such assessments, audits and reviews are reported to the Audit
Committee and the Board.

While we have continually matured our security program and capabilities and have had no material incidents to date, cyber threats 
continue to evolve and there can be no assurance that our efforts will prevent cybersecurity attacks or breaches in our systems such as 
those described in the risk factor entitled, “We are subject to information technology system failures, network disruptions and breaches in 
data security” under “Item 1A. Risk Factors” of this Form 10-K.  

Cybersecurity Governance 

Ecolab’s ISSC, chaired by our CISO meets as needed. The Committee is comprised of executive leaders including the Chief Information 
Officer (“CIO”), Chief Digital Officer, Chief Operating Officer, Chief Financial Officer, Chief Technology Officer, the General Counsel, the 
Executive Vice Presidents of our commercial divisions, the Executive Vice President Global Supply Chain, the Executive Vice President 
Human Resources, the Vice President of Enterprise Business Solutions, and the Vice President Internal Audit. 

The ISSC assists the CISO in fulfilling our responsibilities regarding our information security program to protect the confidentiality, 
integrity and availability of our information assets, financial assets, and information systems. ISSC responsibilities include, but are not 
limited to, evaluation of relevant information security risks, prioritization of information security initiatives, determination of, and advocacy 
for, appropriate investments, review of related legal and regulatory compliance initiatives, review of effective security communication 
initiatives, establishing specific requirements of the program in documented policies which all Ecolab associates, customers, and partners 
are obligated to follow, partner with Ecolab’s business, functional and regional leaders to ensure effective, risk-based security controls 
and practices are in place to achieve the program’s intent, and assist in monitoring the integrity and evaluating the effectiveness of the 
program. 

The Board, in coordination with the Audit Committee, provides oversight of our ERM program, including the management of risks arising 
from cybersecurity threats. The Board and the Audit Committee each receive an overview from our CIO and CISO regarding our 
cybersecurity threat risk management and strategy processes. These reports cover a wide range of topics, and may include current and 
emerging cybersecurity threat risks, third-party assessments, risk-mitigation tactics and programs, information security considerations 
arising with respect to our peers and third parties, and our incident response plan. 

Through a risk-based approach consistent with Ecolab’s ERM framework, the CISO identifies cyber incidents that are brought forward to 
a cross-functional cyber-incident response team including our CEO, CFO, CIO, General Counsel, CISO and Executive Vice President 
Supply Chain. This cyber incident response team, or, in the event of more minor incidents, the CISO and her team, takes steps to 
promptly assess and address the incident, including engaging third parties according to pre-established guidelines. The Board and the 
Audit Committee also receive prompt and timely information regarding any cybersecurity incident that meets established reporting 
thresholds, including ongoing updates regarding any such incident until it has been addressed. 

Ecolab’s cybersecurity program is led by our CISO, who holds a CISO certification. She has been our CISO since 2020 and has more 
than 35 years of information systems experience in total.

Item 2. Properties. 

We operate 32 manufacturing facilities in 14 states in the U.S. Internationally, we operate 68 manufacturing facilities in 38 countries. We 
own most of our manufacturing locations. Our manufacturing philosophy is to manufacture products wherever an economic, process or 
quality assurance advantage exists or where proprietary manufacturing techniques dictate in-house production. Currently, most products 
that we sell are manufactured at our facilities. We position our manufacturing locations and warehouses in a manner to permit ready 
access to our customers. In general, manufacturing facilities located in the United States serve our U.S. markets and facilities located 
outside of the United States serve our international markets. However, most of the United States facilities do manufacture products for 
export. Many of our properties are used by multiple segments.  

Our manufacturing facilities produce chemical products as well as medical devices and equipment for all our operating segments, 
although Pest Elimination purchases the majority of their products and equipment from outside suppliers. Our chemical production 
process consists of blending purchased raw materials into finished products in powder, liquid, and solid form. Additionally, intermediates 
from reaction chemistries are used in some of the blends and are also packaged directly into finished goods. Our devices and equipment 
manufacturing operations consist of producing chemical product dispensers and injectors and other mechanical equipment, medical 
devices, dishwasher racks, related sundries, dish machine refurbishment and water monitoring and maintenance equipment system from 
purchased components and subassemblies. 

Generally, our manufacturing facilities are adequate to meet our existing in-house production needs. We continue to invest in our plant 
sites to maintain viable operations and to add capacity as necessary to meet business imperatives.  

Most of our manufacturing plants also serve as distribution centers. In addition, we operate distribution centers around the world, most of 
which are leased, and utilize third party logistics service providers to facilitate the distribution of our products and services.  

Our corporate headquarters is comprised of a 17-story building that we own in St. Paul, Minnesota. We also own a 115-acre campus in 
Eagan, Minnesota that houses a significant research and development center and training facilities as well as several of our 
administrative functions. We also have a significant business presence in Naperville, Illinois, where our Water and Paper operating 
segments maintain their principal administrative offices and research center, as well as in Greensboro, North Carolina, where our 
Specialty operating segment maintains its principal administrative offices and a research center. Our Water operating segment leases 
administrative and research facilities in Houston, Texas. Our Purolite business maintains leased and owned facilities in the greater King 
of Prussia, PA area for administrative functions, and research and development. 

Significant regional administrative and/or research facilities are located in Campinas, Brazil; Leiden, Netherlands, which we own; and in 
Bangalore, India; Dubai, UAE; Monheim, Germany; Pune, India; Singapore; Shanghai, China; and Zurich, Switzerland, which we lease. 
We also have a network of small leased sales offices in the United States and, to a lesser extent, in other parts of the world.

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

The following management discussion and analysis (“MD&A”) provides information that we believe is useful in understanding our 
operating results, cash flows and financial condition. We provide quantitative information about the material sales drivers including the 
impact of changes in volume and pricing and the effect of acquisitions and changes in foreign currency at the corporate and reportable 
segment level. We also provide quantitative information regarding special (gains) and charges, discrete tax items and other significant 
factors we believe are useful for understanding our results. Such quantitative drivers are supported by comments meant to be qualitative 
in nature. Qualitative factors are generally ordered based on estimated significance. 

The discussion should be read in conjunction with the consolidated financial statements and related notes included in this Form 10-K. 
Our consolidated financial statements are prepared in accordance with U.S. GAAP. This discussion contains various Non-GAAP 
Financial Measures and also contains various forward-looking statements within the meaning of the Private Securities Litigation Reform 
Act of 1995. We refer readers to the statements and information set forth in the sections entitled “Non-GAAP Financial Measures” at the 
end of this MD&A, and “Forward-Looking Statements” and “Risk Factors” within Items 1 and 1A of this Form 10-K. We also refer readers 
to the tables within the section entitled “Results of Operations” of this MD&A for reconciliation information of Non-GAAP measures to U.S. 
GAAP. 

Comparability of Results 

Purolite acquisition 

In December 2021, we acquired Purolite for total consideration of $3.7 billion in cash, net of cash acquired. Purolite is a leading and fast-
growing global provider of high-end ion exchange resins for the separation and purification of solutions for pharmaceutical and industrial 
applications. Headquartered in King of Prussia, Pennsylvania, Purolite operates in more than 30 countries. Purolite is reported within our 
Life Sciences operating segment. Acquisition and integration charges are recorded within special (gains) and charges. The 2021 impacts 
of the Purolite acquisition including operating results, acquisition-related amortization and interest expense related to the transaction 
were also excluded from 2021 adjusted results.  

Impact of Acquisitions and Divestitures 

Our non-GAAP financial measures for organic sales, organic operating income and organic operating income margin are at fixed 
currency and exclude the impact of special (gains) and charges, the results of our acquired businesses from the first twelve months post 
acquisition and the results of divested businesses from the twelve months prior to divestiture. As part of the separation of ChampionX in 
2020, we entered into a Master Cross Supply and Product Transfer agreement with ChampionX to provide, receive or transfer certain 
products for a period of 36 months and for a small set of products with limited suppliers over the next few years. Sales of product to 
ChampionX under this agreement are recorded in product and equipment sales in the Corporate segment along with the related cost of 
sales. These transactions are removed from the consolidated results as part of the calculation of the impact of acquisitions and 
divestitures. 

Comparability of Reportable Segments 

Effective January 1, 2023, our former Downstream operating segment is now part of the Water operating segment. This change did not 
have any impact on the Global Industrial reportable segment. 

Fixed Currency Foreign Exchange Rates 

Management evaluates the sales and operating income performance of our non-U.S. dollar functional currency international operations 
based on fixed currency exchange rates, which eliminate the impact of exchange rate fluctuations on our international operations. Fixed 
currency amounts are updated annually at the beginning of each year based on translation into U.S. dollars at foreign currency exchange 
rates established by management, with all periods presented using such rates. Public currency rate data provided within the “Segment 
Performance” section of this MD&A reflect amounts translated at actual public average rates of exchange prevailing during the 
corresponding period and is provided for informational purposes only. 

25 

EXECUTIVE SUMMARY 

In 2023, we delivered high single digit sales growth as we continued strong pricing. Our strong pricing offset continued delivered product 
cost increases. Our team generated double-digit sales growth in Institutional & Specialty, high single digit sales growth in Industrial, and 
Other segments while Healthcare and Life Sciences generated good sales growth. Operating income grew by strong double digits, as 
strong pricing and cost savings initiatives overcame investments in the business and higher supply chain costs. 

Sales 

Reported sales increased 8% to $15.3 billion in 2023 from $14.2 billion in 2022. When measured in fixed rates of foreign currency 
exchange, fixed currency sales increased 8% compared to the prior year. Organic sales increased 9% compared to the prior year. 

Gross Margin 

Our reported gross margin was 40.2% of sales for 2023, compared to our 2022 reported gross margin of 37.8%. Excluding the impact of 
special (gains) and charges included in cost of sales, our adjusted gross margin was 40.4% in 2023 and 38.2% in 2022. Our gross profit 
increased as our strong pricing exceeded delivered product cost inflation.  

Operating Income 

Reported operating income increased 28% to $2.0 billion in 2023, compared to $1.6 billion in 2022. Adjusted operating income, excluding 
the impact of special (gains) and charges increased 20% in 2023 as strong pricing overcame investments in the business including 
incentive compensation, unfavorable mix and higher supply chain costs. Organic operating income increased 20% in 2023. 

Earnings from Continuing Operations Attributable to Ecolab Per Common Share (“EPS”)  

Reported diluted EPS increased 26% to $4.79 in 2023 compared to $3.81 in 2022. Special (gains) and charges had an impact on both 
years. Special (gains) and charges in 2023 were driven primarily by restructuring expense and 2022 was driven primarily by restructuring 
and pension settlement expense. Adjusted diluted EPS, which excludes the impact of special (gains) and charges and discrete tax items 
increased 16% to $5.21 in 2023 compared to $4.49 in 2022 as our strong operating income performance was partially offset by foreign 
currency translation and increases in interest expense.  

Balance Sheet 

We remain committed to maintaining “A” range ratings metrics over the long-term, supported by our current credit ratings of A-/A3/A- by 
Standard & Poor’s, Moody’s Investor Services and Fitch, respectively. Our strong balance sheet has allowed us continued access to 
capital at attractive rates. 

Cash Flow 

Cash flow from operating activities was $2.4 billion in 2023 compared to $1.8 billion in 2022. We continued to generate strong cash flow 
from operations, allowing us to fund our ongoing operations, investments in our business, acquisitions, debt repayments, pension 
obligations and return cash to our shareholders through share repurchases and dividend payments.  

Dividends  

Dividends declared per common share in 2023 was $2.16 per share. In December 2023 we increased our quarterly cash dividend by 8% 
to $0.57 per share, representing our 32nd consecutive annual dividend rate increase. We have paid cash dividends on our common 
shares for 87 consecutive years. Our outstanding dividend history reflects our long-term growth and development, strong cash flows, 
solid financial position and confidence in our business prospects for the years ahead. 

26 

CRITICAL ACCOUNTING ESTIMATES 

Our consolidated financial statements are prepared in accordance with U.S. GAAP. We have adopted various accounting policies to 
prepare the consolidated financial statements in accordance with U.S. GAAP. Our significant accounting policies are disclosed in Note 2 
of the Notes to the Consolidated Financial Statements (“Notes”). 

Preparation of our consolidated financial statements, in conformity with U.S. GAAP, requires us to make estimates and assumptions that 
affect the amounts reported in the consolidated financial statements and accompanying notes. Estimates are considered to be critical if 
they meet both of the following criteria: (1) the estimate requires assumptions to be made about matters that are highly uncertain at the 
time the accounting estimate is made, and (2) different estimates that we reasonably could have used for the accounting estimate in the 
current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, have a material impact on 
the presentation of our financial condition or results of operations. 

Besides estimates that meet the “critical” estimate criteria, we make many other accounting estimates in preparing our financial 
statements and related disclosures. All estimates, whether or not deemed critical, affect reported amounts of assets, liabilities, revenues 
or expenses as well as disclosures of contingent assets and liabilities. Estimates are based on experience and other information 
available prior to the issuance of the financial statements. Materially different results can occur as circumstances change and additional 
information becomes known, even from estimates not deemed critical. Our critical accounting estimates include the following: 

Revenue Recognition 

Revenue is measured as the amount of consideration expected to be received in exchange for transferring goods or providing service. 
Revenue from product and sold equipment is recognized when obligations under the terms of a contract with the customer are satisfied, 
which generally occurs with the transfer of the product or delivery of the equipment. Revenue from service and leased equipment is 
recognized when the services are provided, or the customer receives the benefit from the leased equipment, which is over time. Service 
revenue is recognized over time utilizing an input method and aligns with when the services are provided. Typically, revenue is 
recognized over time using costs incurred to date because the effort provided by the field selling and service organization represents 
services provided, which corresponds with the transfer of control. Revenue for leased equipment is accounted for under Topic 842 
Leases and recognized on a straight-line basis over the length of the lease contract. 

Our revenue policies do not provide for general rights of return. We record estimated reductions to revenue for customer programs and 
incentive offerings including pricing arrangements, promotions and other volume-based incentives based primarily on historical 
experience and anticipated performance over the contract period. Depending on market conditions, we may increase customer incentive 
offerings, which could reduce gross profit margins over the term of the incentive. We also record estimated reserves for product returns 
and credits based on specific circumstances and credit conditions. We record an allowance for uncollectible accounts based on our 
estimates of expected future credit losses.  

The revenue standard can be applied to a portfolio of contracts with similar characteristics if it is reasonable that the effects of applying 
the standard at the portfolio would not be significantly different than applying the standard at the individual contract level. We apply the 
portfolio approach primarily within each operating segment by geographical region. Application of the portfolio approach was focused on 
those characteristics that have the most significant accounting consequences in terms of their effect on the timing of revenue recognition 
or the amount of revenue recognized. We determined the key criteria to assess with respect to the portfolio approach, including the 
related deliverables, the characteristics of the customers and the timing and transfer of goods and services, which most closely aligned 
within the operating segments. In addition, the accountability for the business operations, as well as the operational decisions on how to 
go to market and the product offerings, are performed at the operating segment level. For additional information on revenue recognition, 
refer to Note 17. 

Litigation and Environmental Liabilities 

Our business and operations are subject to extensive environmental laws and regulations governing, among other things, air emissions, 
wastewater discharges, the use and handling of hazardous substances, waste disposal and the investigation and remediation of soil and 
groundwater contamination. Some risk of environmental liability is inherent in our operations. 

We record liabilities related to pending litigation, environmental claims and other contingencies when a loss is probable and can be 
reasonably estimated. Estimates used to record such liabilities are based on our best estimate of probable future costs. We record the 
amounts that represent the points in the range of estimates that we believe are most probable or the minimum amount when no amount 
within the range is a better estimate than any other amount. Potential insurance reimbursements generally are not anticipated in our 
accruals for environmental liabilities or other insured losses. Expected insurance proceeds are recorded as receivables when recovery is 
deemed certain. While the final resolution of litigation and environmental contingencies could result in amounts different than current 
accruals, and therefore have an impact on our consolidated financial results in a future reporting period, we believe the ultimate outcome 
will not have a significant impact on our consolidated financial position. For additional information on our commitments and 
contingencies, refer to Note 15. 

27 

Actuarially Determined Liabilities 

Pension and Postretirement Healthcare Benefit Plans 

The measurement of our pension and postretirement benefit obligations are dependent on a variety of assumptions determined by 
management and used by our actuaries in their valuations and calculations. These assumptions affect the amount and timing of future 
pension contributions, benefit payments and expense or income recognized. 

The significant assumptions used in developing the required estimates are the discount rates, expected returns on assets, projected 
salary and health care cost increases and mortality tables. 









The discount rate assumptions for our U.S. plans are assessed using a yield curve constructed from a subset of bonds yielding
greater than the median return from a population of non-callable, corporate bonds that have an average rating of AA when
averaging available Moody’s Investor Services, Standard & Poor’s and Fitch ratings. The discount rates are calculated by matching
each plans’ projected cash flows to the bond yield curve. For 2023 and 2022, we measured service and interest costs by applying
the specific spot rates along that yield curve to the plans’ liability cash flows. We believe this approach provides a more precise
measurement of service and interest costs by aligning the timing of the plans’ liability cash flows to the corresponding spot rates on
the yield curve. In determining our U.S. pension obligations for 2023, our weighted-average discount rate decreased to 4.95% from
5.17% at year-end 2022. In determining our U.S. postretirement health care obligation for 2023, our weighted-average discount rate
decreased to 4.95% from 5.14% at year-end 2022.

The expected rate of return on plan assets reflects asset allocations, investment strategies and views of investment advisors, and
represents our expected long-term return on plan assets. Our weighted-average expected returns on U.S. plan assets used in
determining the U.S. pension and U.S. postretirement health care expenses was 7.75% for 2023 and 7.00% for 2022 and 2021.

Projected salary is based on our long-term actual experience, the near-term outlook and assumed inflation. Our weighted-average
projected salary increase used in determining the U.S. pension expenses was 4.03% for 2023, 2022 and 2021.

For postretirement benefit measurement purposes as of December 31, 2023, the annual rates of increase in the per capita cost of
covered health care were assumed to be 7.46% for pre-65 costs. Post-65 costs are no longer used. The rates are assumed to
decrease each year until they reach 4.5% in 2034 and remain at those levels thereafter.

 We use mortality tables appropriate in the circumstances, which generally are the recently available mortality tables as of the

respective U.S. and international measurement dates. Our year-end U.S. valuations reflect mortality tables that estimate the impacts
of COVID in an endemic state. This represents a change from prior year when the impact of COVID on future mortality could not be
reasonably estimated.

The effects of actual results differing from our assumptions, as well as changes in assumptions, are reflected in the unrecognized gains 
or losses and amortized into earnings in the future. Significant differences in actual experience or significant changes in assumptions 
may materially affect future pension and other postretirement obligations and income or expense. The unrecognized net losses on our 
U.S. qualified and non-qualified pension plans increased to $495 million as of December 31, 2023 from $412 million as of December 31, 
2022 (both before tax), primarily due to lower actual return on assets partially offset by current year net actuarial gains. 

The effect of a decrease in the discount rate or decrease in the expected return on assets assumption as of December 31, 2023, on the 
December 31, 2023 defined benefit obligation and 2024 expense is shown below, assuming no changes in benefit levels. Expense 
amounts reflect the accounting for gains or losses as a component of other comprehensive income or expense and recognition of the 
impacts into earnings over time:

Our international pension obligations and underlying plan assets represent approximately one third of our global pension plans, with the 
majority of the amounts held in the U.K. and Eurozone countries. We use assumptions similar to our U.S. plan assumptions to measure 
our international pension obligations, however, the assumptions used vary by country based on specific local country requirements and 
information. 

Refer to Note 16 for further discussion concerning our accounting policies, estimates, funded status, contributions and overall financial 
positions of our pension and postretirement plan obligations. 

Self-Insurance 

Globally we have insurance policies with varying deductible levels for property and casualty losses. We are insured for losses in excess 
of these deductibles, subject to policy terms and conditions and have recorded both a liability and an offsetting receivable for amounts in 
excess of these deductibles. We are self-insured for health care claims for eligible participating employees, subject to certain deductibles 
and limitations. We determine our liabilities for claims on an actuarial basis.  

Income Taxes 

Judgment is required to determine the annual effective income tax rate, deferred tax assets and liabilities, valuation allowances recorded 
against net deferred tax assets and unrecognized tax benefits. 

Effective Income Tax Rate 

Our effective income tax rate is based on annual income, statutory tax rates and tax planning available in the various jurisdictions in 
which we operate. Our annual effective income tax rate includes the impact of unrecognized tax benefits. We recognize the amount of tax 
benefit that is greater than 50% likely of being realized upon settlement with a taxing authority. We adjust these liabilities for 
unrecognized tax benefits in light of changing facts and circumstances.  

Tax regulations require items to be included in our tax returns at different times than the items are reflected in our financial statements. 
As a result, the effective income tax rate reflected in our financial statements differs from that reported in our tax returns. Some of these 
differences are permanent, such as expenses that are not deductible on our tax return, and some are temporary differences, such as 
depreciation expense. 

Deferred Tax Assets and Liabilities and Valuation Allowances 

Deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and tax bases of assets 
and liabilities, applying enacted tax rates expected to be in effect for the year in which the differences are expected to reverse. Based on 
the evaluation of available evidence, both positive and negative, we recognize tax assets, such as net operating loss carryforwards and 
tax credit carryforwards, to the extent that realizing these benefits is considered to be more likely than not. Relevant factors in 
determining the realizability of deferred tax assets include historical results, sources of future taxable income, the expected timing of the 
reversal of temporary differences, tax planning strategies and the expiration dates of the various tax attributes.  

Unrecognized Tax Benefits 

A number of years may elapse before a particular tax matter, for which we have established a liability for unrecognized tax benefits, is 
audited and finally resolved. The number of tax years with open tax audits varies depending on the tax jurisdiction. The Internal Revenue 
Service (“IRS”) has completed examinations of our U.S. federal income tax returns through 2016 and the years 2017 through 2020 are 
currently under audit. In addition to the U.S. federal examinations, we have ongoing audit activity in several U.S. state and foreign 
jurisdictions. 

The tax positions we take are based on our interpretations of tax laws and regulations in the applicable federal, state and international 
jurisdictions. We believe our tax returns properly reflect the tax consequences of our operations, and our liabilities for unrecognized tax 
benefits are appropriate and sufficient for the positions taken. Because of the uncertainty of the final outcome of these examinations, we 
have established a liability for potential reductions of tax benefits (including related interest and penalties) for amounts that do not meet 
the more-likely-than-not thresholds for recognition and measurement as required by authoritative guidance. The liability for unrecognized 
tax benefits is reviewed throughout the year, taking into account new legislation, regulations, case law and audit results. Settlement of 
any particular issue could result in offsets to other balance sheet accounts, cash payments or receipts and/or adjustments to tax 
expense. Liabilities for unrecognized tax benefits are presented in the Consolidated Balance Sheets within other non-current liabilities. 
Our gross liability for unrecognized tax benefits was $24.2 million and $24.9 million as of December 31, 2023 and 2022, respectively. For 
additional information on income taxes refer to Note 12.

Long-Lived Assets, Intangible Assets and Goodwill 

Long-Lived and Amortizable Intangible Assets 

Purchased long-lived and amortizable intangible assets not acquired as part of a business combination are recorded as of their 
acquisition date at cost, whereas long-lived and amortizable assets acquired as part of a business combination are recorded as of their 
acquisition date at their fair values based on the fair value requirements defined in U.S. GAAP. This requires us to make significant 
estimates and assumptions relating to the present value of its future cash flows, such as growth rates, royalty rates or discount rates. 

We review our long-lived and amortizable intangible assets, the net value of which was $6.3 billion as of December 31, 2023 and 2022, 
for impairment when significant events or changes in business circumstances indicate that the carrying amount of the assets may not be 
recoverable. Such circumstances may include a significant decrease in the market price of an asset or asset group, a significant adverse 
change in the manner in which asset or asset groups are being used or history of operating or cash flow losses associated with the use 
of the asset or asset group. Impairment losses could occur when the carrying amount of an asset or asset group exceeds the anticipated 
future undiscounted cash flows expected to result from the use of the asset or asset group and its eventual disposition. The amount of 
the impairment loss to be recorded, if any, is calculated as the excess of the asset’s or assets group’s carrying amount over its estimated 
fair value.  

We use the straight-line method to recognize amortization expense related to our amortizable intangible assets, including our customer 
relationships. We consider various factors when determining the appropriate method of amortization for our customer relationships, 
including projected sales data, customer attrition rates and length of key customer relationships. 

Globally, we have a broad customer base. Our retention rate of significant customers has aligned with our acquisition assumptions, 
including the customer bases acquired from our Nalco, Laboratoires Anios (“Anios”), Copal Invest NV, including its primary operating 
entity CID Lines (collectively, “CID Lines”) and Purolite transactions, which make up the majority of our unamortized customer 
relationships. Our historical retention rates, coupled with our consistent track record of keeping long-term relationships with our 
customers, supports our expectation of consistent sales generation for the foreseeable future from the acquired customer bases. If our 
customer retention rates or other post-acquisition operational activities change materially, we would evaluate the financial impacts and 
significance of the events given rise to the change which could result in impairment of our customer relationship intangible assets, or 
absent an impairment, an acceleration of amortization expense. 

In addition, we periodically reassess the estimated remaining useful lives of our long-lived and amortizable intangible assets. Changes to 
estimated useful lives would impact the amount of depreciation and amortization expense recorded in earnings. We have experienced no 
significant changes in the carrying amount or estimated remaining useful lives of our long-lived or amortizable intangible assets. 

Goodwill and Indefinite Life Intangible Assets 

Goodwill arises from our acquisitions and represents the excess of the fair value of the purchase consideration exchanged over the fair 
value of net assets acquired. We had total goodwill of $8.1 billion and $8.0 billion as of December 31, 2023 and 2022, respectively. We 
test our goodwill for impairment at the reporting unit level. Our reporting units are our ten operating segments. We assess goodwill for 
impairment on an annual basis during the second quarter. If circumstances change or events occur that demonstrate it is more likely than 
not that the carrying amount of a reporting unit exceeds its fair value, we complete an interim goodwill impairment assessment of that 
reporting unit prior to the next annual assessment. If the results of an annual or interim goodwill impairment assessment demonstrate the 
carrying amount of a reporting unit is greater than its fair value, we will recognize an impairment loss for the amount by which the 
reporting unit’s carrying amount exceeds its fair value, but not to exceed the carrying amount of goodwill assigned to that reporting unit.  

For our annual 2023 goodwill impairment assessment, we completed our impairment assessment for our ten reporting units using 
discounted cash flow analyses that incorporated assumptions regarding future growth rates, terminal values and discount rates. Our 
goodwill impairment assessments for 2023 indicated the estimated fair values of each of these ten reporting units exceeded the carrying 
amounts of the respective reporting units by a significant margin. We evaluate the need to complete interim goodwill impairment 
assessments when significant events or changes in business circumstances indicate that it is more likely than not that the carrying 
amount of a reporting unit may be higher than its fair value. No events were noted during the second half of 2023 that required 
completion of an interim goodwill impairment assessment in the second half of 2023 for any of our ten reporting units. There has been no 
impairment of goodwill in any of the periods presented.  

The Nalco trade name is our only indefinite life intangible asset, which is tested for impairment on an annual basis during the second 
quarter. For our annual 2023 indefinite life intangible asset impairment assessment, we completed our impairment assessment of the 
Nalco trade name using the relief from royalty discounted cash flow method, which incorporates assumptions regarding future sales 
projections, royalty rates and discount rates. Our Nalco tradename impairment assessment for 2023 indicated the estimated fair value of 
the Nalco trade name exceeded its $1.2 billion carrying amount by a significant margin. No events were noted during the second half of 
2023 that required completion of an interim impairment assessment of our Nalco trade name in the second half of 2023. There has been 
no impairment of the Nalco trade name intangible since it was acquired.

Our COS values and corresponding gross margin are shown above. Our gross margin is defined as sales less cost of sales divided by 
sales. 

Our reported gross margin was 40.2%, 37.8%, and 40.2% for 2023, 2022 and 2021, respectively. Our 2023, 2022 and 2021 reported 
gross margins were negatively impacted by special (gains) and charges of $22.5 million, $69.9 million, and $93.9 million, respectively. 
Special (gains) and charges items impacting COS are shown within the “Special (Gains) and Charges” table below. 

Excluding the impact of special (gains) and charges, our 2023 adjusted gross margin was 40.4% compared against a 2022 adjusted 
gross margin of 38.2%. The increase primarily reflected accelerating pricing that overcame higher supply chain costs. 

Excluding the impact of special (gains) and charges and the 2021 impacts of the Purolite transaction, our adjusted gross margin was 
38.2% and 40.9% for 2022 and 2021, respectively. The decrease primarily reflected accelerating pricing that was more than offset by 
higher delivered product cost and unfavorable mix.

The increased SG&A ratio (SG&A expenses as a percentage of reported net sales) comparing 2023 against 2022 was driven by higher 
incentive compensation compared to last year which was partially offset by strong productivity including cost savings initiatives. The 
decreased SG&A ratio (SG&A expenses as a percentage of reported net sales) comparing 2022 against 2021 was driven primarily by 
strong productivity including cost savings initiatives, partially offset by higher cost of compensation compared to last year.

Restructuring Activities 

Restructuring activities are primarily related to the Combined Program which is described below. These activities have been included as 
a component of cost of sales, special (gains) and charges, and other (income) expense on the Consolidated Statements of Income. 
Restructuring liabilities have been classified as a component of other current and other noncurrent liabilities on the Consolidated Balance 
Sheets. 

Further details related to our restructuring charges are included in Note 3. 

Combined Program 

In November 2022, we approved a Europe cost savings program. In connection with these actions, we expected to incur pre-tax charges 
of $130 million ($110 million after tax) or $0.38 per diluted share. In February 2023, we expanded our previously announced Europe cost 
savings program to focus on its Institutional and Healthcare businesses in other regions. In connection with the expanded program 
(“Combined Program”), we expect to incur total pre-tax charges of $195 million ($150 million after tax) or $0.52 per diluted share. We 
expect that these restructuring charges will be completed by the end of 2024. Program actions include headcount reductions from 
terminations, not filling certain open positions, and facility closures. The Combined Program charges are expected to be primarily cash 
expenditures related to severance and asset disposals. 

In anticipation of this Combined Program, a limited number of actions were taken in the fourth quarter of 2022. As a result, we 
reclassified $19.3 million ($14.5 million after tax) or $0.05 per diluted share from other restructuring to the Combined Program in the first 
quarter of 2023. 

In 2023 and 2022 we recorded total Combined Program restructuring charges of $77.7 million ($66.4 million after tax) or $0.23 per diluted 
share and $67.2 million ($56.0 million after tax) or $0.20 per diluted share, respectively. We have recorded $164.2 million ($136.9 million 
after tax), or $0.48 per diluted share of cumulative charges under the Combined Plan. The net liability related to the Combined Program 
was $43.1 million and $62.0 million as of December 31, 2023 and 2022, respectively. The remaining liability is expected to be paid over a 
period of a few months to several quarters and will continue to be funded from operating activities. 

32 

 
 
 
 
 
 
 
 
 
 
 
The Combined Program has delivered $131 million of cumulative cost savings with estimated annualized cost savings of $175 million in 
continuing operations by 2024. 

Institutional Advancement Program 

We approved a restructuring plan in 2020 focused on the Institutional business (“the Institutional Plan”) which is intended to enhance our 
Institutional sales and service structure and allow the sales team to capture share and penetration while maximizing service effectiveness 
by leveraging our ongoing investments in digital technology. 

In 2023, 2022 and 2021, we recorded total restructuring charges of $8.0 million ($6.0 million after tax) or $0.03 per diluted share, $6.3 
million ($4.8 million after tax) or $0.02 per diluted share and $12.6 million ($10.2 million after tax) or $0.04 per diluted share, respectively, 
primarily related to severance, disposals of equipment and office closures. The Restructuring activities were completed at the end of 
2023, with total costs of $62.1 million ($47.4 million after tax), or $0.17 per diluted share. Net cash payments were $2.6 million and non-
cash net charges were $6.8 million in 2023. There was no remaining liability related to the Institutional Plan as of December 31, 2023. 
There was $1.9 million of liability related to the Institutional Plan of December 31, 2022. 

The Institutional Plan has delivered $55 million of annual cost savings.  

Accelerate 2020 

During 2018, we formally commenced a restructuring plan Accelerate 2020 (“the A2020 Plan”), to leverage technology and system 
investments and organizational changes. The goals of the A2020 Plan were to further simplify and automate processes and tasks, 
reduce complexity and management layers, consolidate facilities and focus on key long-term growth areas by further leveraging 
technology and structural improvements. We recorded restructuring charges of $9.9 million ($8.4 million after tax) or $0.03 per diluted 
share and $5.3 million ($6.2 million after tax) or $0.02 per diluted share in 2022 and 2021, respectively. The restructuring activities were 
completed at the end of 2022, with total costs of $254.4 million ($198.4 million after tax), or $0.69 per diluted share. 

Net cash payments were $13.2 million during 2023. The liability related to the A2020 Plan was $4.9 million and $18.1 million as of 
December 31, 2023 and 2022, respectively. The remaining liability is expected to be paid over a period of a few months to several 
quarters which continue to be funded from operating activities. 

The A2020 Plan has delivered $315 million of annual cost savings. 

Other Restructuring Activities 

During 2022 and 2021, we incurred restructuring charges of $23.8 million ($17.9 million after tax), or $0.06 per diluted share and $18.7 
million ($17.0 million after tax), or $0.06 per diluted share, respectively, related to other immaterial restructuring activity. The charges 
primarily related to severance and asset write-offs. 

The restructuring liability balance for all other restructuring plans excluding the Combined Program, A2020 Plan and the Institutional Plan 
were $3.3 million and $23.2 million as of December 31, 2023 and 2022, respectively. The decrease in liability was driven primarily by the 
reclass of $19.3 million from other restructuring to the Combined Program in the first quarter of 2023. The remaining liability is expected 
to be paid over a period of a few months to several quarters and will continue to be funded from operating activities. Cash payments 
during 2023 related to all other restructuring plans excluding the Combined Program, A2020 and Institutional Plan were $0.6 million. 

Acquisition and integration related costs 

Acquisition and integration related costs reported in special (gains) and charges on the Consolidated Statements of Income in 2023 
include $16.1 million ($12.0 million after tax) or $0.04 per diluted share. Charges are integration related costs primarily related to the 
Purolite Corporation (“Purolite”) acquisition. 

Acquisition and integration related costs reported in special (gains) and charges on the Consolidated Statements of Income in 2022 
include $14.5 million ($11.4 million after tax) or $0.04 per diluted share. Charges are related primarily to the Purolite acquisition and 
consist of integration related costs, advisory and legal fees. Acquisition and integration related costs reported in product and equipment 
cost of sales on the Consolidated Statements of Income in 2022 include $25.0 million ($19.6 million after tax) or $0.07 per diluted share. 
Charges are related primarily to the recognition of fair value step-up in the Purolite inventory and other integration costs.  

Acquisition and integration related costs reported in special (gains) and charges on the Consolidated Statements of Income in 2021 
include $29.9 million ($23.5 million after tax) or $0.08 per diluted share. Charges are primarily related to the Purolite acquisition and 
consisted of deal costs, integration costs and advisory and legal fees. Acquisition and integration related costs reported in product and 
equipment cost of sales on the Consolidated Statements of Income in 2021 include $4.2 million ($3.3 million after tax) or $0.01 per 
diluted share and are related to the recognition of fair value step-up in the Purolite inventory. In conjunction with its acquisitions, we 
incurred $0.8 million ($0.6 million after tax), or less than $0.01 per diluted share, of special (gains) and charges reported in interest 
expense in 2021. 

33 

Russia/Ukraine 

In light of Russia’s invasion of Ukraine and the sanctions against Russia by the United States and other countries, we have made the 
determination that we will limit our Russian business to operations that are essential to life, providing minimal support for our healthcare, 
life sciences, food and beverage and certain water businesses. We incurred charges of $1.4 million ($1.1 million after tax) or less than 
$0.01 per diluted share and $13.1 million ($12.6 million after tax) or $0.04 per diluted share during 2023 and 2022, respectively, primarily 
related to recoverability risk of certain assets in both Russia and Ukraine. 

Other operating activities 

Other operating activities recorded in cost of sales on the Consolidated Statements of Income of $16.3 million ($12.7 million after tax), or 
$0.04 per diluted share in 2022, and $65.0 million ($49.2 million after tax), or $0.17 per diluted share in 2021 relate primarily to COVID-19 
activities. 

Other operating activities recorded in special (gains) and charges on the Consolidated Statements of Income of $30.7 million ($23.3 
million after tax), or $0.08 per diluted share in 2023 relate primarily to certain legal charges. Other operating activities recorded in special 
(gains) and charges on the Consolidated Statements of Income of $34.3 million ($25.7 million after tax), or $0.09 per diluted share in 
2022 and $60.8 million ($46.4 million after tax), or $0.16 per diluted share in 2021 relate primarily to COVID-19 activities and certain legal 
charges. 

Other (income) expense 

During 2022 and 2021, we incurred settlement expense recorded in other (income) expense on the Consolidated Statements of Income 
of $50.6 million ($38.2 million after tax) or $0.13 per diluted share and $37.2 million ($28.7 million after tax) or $0.10 per diluted share, 
respectively, related to U.S. pension plan lump-sum payments to retirees. 

Interest expense, net 

During 2021 we recorded special charges of $32.3 million ($28.4 million after tax) or $0.10 per diluted share in interest expense on the 
Consolidated Statements of Income related to debt issuance and refinancing charges.

Our operating income and corresponding operating income margin are shown in the previous tables. Operating income margin is defined 
as operating income divided by sales. 

Our reported operating income was $1,992.3 million, $1,562.5 million and $1,598.6 for 2023, 2022 and 2021, respectively. Our 2023, 
2022 and 2021 operating incomes were negatively impacted by special (gains) and charges and the 2021 impact of Purolite on operating 
income of $133.9 million, $210.4 million, and $200.3 million, respectively.  

Excluding the impacts of special (gains) and charges 2023 adjusted operating income increased 20% as strong pricing overcame 
investments in the business including incentive compensation, higher supply chain costs and unfavorable mix. Excluding the impacts of 
special (gains) and the 2021 impact of Purolite on operating income 2022 adjusted operating income decreased 1% driven by 
accelerating pricing covering substantially higher delivered product costs, which was offset by investments in the business.

Our reported other income was $59.9 million, $24.5 million and $33.9 million in 2023, 2022 and 2021, respectively. Other (income) 
expense increased when comparing 2023 against 2022 as higher pension costs were more than offset by the comparison to last year’s 
$50.6 million settlement expense related to U.S. pension plan lump-sum payments to retirees. Other (income) expense decreased when 
comparing 2022 against 2021 primarily due to increased pension settlement charges in 2022 as a result of a higher volume of pension 
settlement activity and higher interest costs associated with rising interest rates throughout 2022. Excluding the impact of settlements 
and curtailments recorded in special (gains) and charges during 2023, 2022 and 2021, our adjusted other income was $59.9 million, 
$75.1 million and $71.1 million, respectively.

Our reported net interest expense totaled $296.7 million, $243.6 million and $218.3 million during 2023, 2022 and 2021, respectively. 

We incurred $33.1 million ($29.0 million after tax) or $0.10 per diluted share of interest expense special charges in conjunction with our 
debt issuances and refinancing activities during 2021. 

Adjusted for special (gains) and charges, the increase in interest expense when comparing 2023 against 2022 was driven primarily by 
the higher average interest rates on outstanding debt. Adjusted for special (gains) and charges, the increase in interest expense when 
comparing 2022 against 2021 was driven primarily by the interest on debt issued to fund the Purolite acquisition and the impact from 
higher average interest rates on floating rate debt.

Our reported tax rate was 20.6%, 17.5%, and 19.1%, for 2023, 2022 and 2021, respectively. The change in our tax rate includes the tax 
impact of special (gains) and charges and discrete tax items, which have impacted the comparability of our historical reported tax rates, 
as amounts included in our special (gains) and charges are derived from tax jurisdictions with rates that vary from our tax rate, and 
discrete tax items are not necessarily consistent across periods. The tax impact of special (gains) and charges and discrete tax items will 
likely continue to impact comparability of our reported tax rate in the future.  

We recognized a net tax expense related to discrete tax items of $11.2 million during 2023. The net discrete tax expense was primarily 
related to the filing of federal, state and foreign tax returns and other income tax adjustments including the impact of changes in tax laws, 
audit settlements, share-based compensation excess tax benefits and other changes in estimates.

We recognized a net tax benefit related to discrete tax items of $11.8 million during 2022. This included a deferred tax benefit of $14.6 
million associated with utilization of tax attributes as a result of legal entity rationalization and share-based compensation excess tax 
benefits of $6.0 million. The remaining discrete tax expense of $8.8 million was primarily related to the filing of federal, state and foreign 
tax returns and other income tax adjustments including the impact of changes in tax laws, audit settlements and other changes in 
estimates. 

We recognized net tax expense of $5.8 million related to discrete tax items during 2021. This included a non-cash deferred tax expense 
of $25.1 million associated with transferring certain intangible property between affiliates. Share-based compensation excess tax benefit 
was $29.1 million. The remaining discrete tax expense of $9.8 million was primarily related to the filing of federal, state, and foreign tax 
returns and other income tax adjustments including the impact of changes in tax law, audit settlements and other changes in estimates.

The change in our adjusted tax rates from 2022 to 2023 was primarily driven by geographic income mix. Future comparability of our 
adjusted tax rate may be impacted by various factors, including but not limited to other changes in global tax rules, further tax planning 
projects and geographic income mix.

SEGMENT PERFORMANCE 

The non-U.S. dollar functional currency international amounts included within our reportable segments are based on translation into U.S. 
dollars at the fixed currency exchange rates established by management for 2023. The difference between the fixed currency exchange 
rates and the actual currency exchange rates is reported as “effect of foreign currency translation” in the following tables. All other 
accounting policies of the reportable segments are consistent with U.S. GAAP and the accounting policies described in Note 2. Additional 
information about our reportable segments is included in Note 18.

We continue to generate cash flow from operations allowing us to fund our ongoing operations, acquisitions, investments in the business 
and pension obligations along with returning cash to our shareholders through dividend payments and share repurchases. 

Cash provided by operating activities increased $623 million in 2023 compared to 2022, driven primarily by a $332 million net favorable 
change in working capital and $284 million increase in net income. The cash flow impact from working capital was primarily driven by 
improvement in inventory due to management efforts following easing global supply chain constraints and an improvement in receivables 
offset by a decrease in accounts payable primarily associated with our inventory reduction efforts.  

Cash provided by operating activities decreased $274 million in 2022 compared to 2021, driven primarily by $277 million increase in 
working capital. The increase in working capital is primarily driven by past due receivables higher than last year due to pricing and energy 
surcharge rollout. Additionally, inventory impacted by inflationary environment and higher stock holding to mitigate supply disruption.  

The impact on operating cash flows of pension and postretirement plan contributions, cash activity related to restructuring, cash paid for 
income taxes and cash paid for interest, are shown in the following table:

Cash used for investing activities is primarily impacted by the timing of business acquisitions and dispositions as well as from capital 
investments in the business. 

We continue to make capital investments in the business, including merchandising and customer equipment and manufacturing facilities. 
Total capital expenditures were $775 million, $713 million and $643 million in 2023, 2022 and 2021, respectively. 

Total cash paid for acquisitions, net of cash acquired and net of cash received from dispositions, in 2023, 2022 and 2021 was $180 
million, $7 million and $3,924 million, respectively. Our acquisitions and divestitures are discussed further in Note 4. We continue to 
target strategic business acquisitions which complement our growth strategy and expect to continue to make capital investments and 
acquisitions in the future to support our long-term growth.

Our cash flows from financing activities primarily reflect the issuances and repayment of debt, common stock repurchases, proceeds from 
common stock issuances related to our equity incentive programs and dividend payments. 

There were no long-term debt issuances in 2023. We repaid $500 million of long-term debt in 2023. We issued $500 million par value 
and received $494 million in proceeds of long-term debt in 2022. We issued $2,800 million par value and received $2,775 million in 
proceeds of long-term debt and repaid $900 million of long-term debt in 2021.The proceeds received from the debt issuances were used 
for the Purolite acquisition, repayment of outstanding debt, repayment of commercial paper and general corporate purposes. In addition, 
we had net repayments of $2 million and $404 million of commercial paper and notes payable in 2023 and 2022, respectively, and net 
issuances of $394 million in 2021.  

Shares are repurchased for the purpose of partially offsetting the dilutive effect of our equity compensation plans, to manage our capital 
structure and to efficiently return capital to shareholders. We repurchased a total of $14 million, $518 million, and $107 million of shares 
in 2023, 2022 and 2021, respectively.  

The impact on financing cash flows of commercial paper and notes payable repayments, long-term debt borrowings and long-term debt 
repayments, are shown in the following table:

In December 2023, we increased our quarterly dividend rate by 8%. This represents the 32nd consecutive year we have increased our 
dividend. We have paid dividends on our common stock for 87 consecutive years. We paid dividends of $617 million, $603 million and 
$566 million in 2023, 2022 and 2021, respectively. Cash dividends declared per share of common stock, by quarter, for each of the last

Liquidity and Capital Resources 

We currently expect to fund all of our cash requirements which are reasonably foreseeable for the next twelve months, including 
scheduled debt repayments, new investments in the business, share repurchases, dividend payments, possible business acquisitions 
and pension and postretirement contributions with cash from operating activities, and as needed, additional short-term and/or long-term 
borrowings. We continue to expect our operating cash flow to remain strong. 

As of December 31, 2023, we had $920 million of cash and cash equivalents on hand, of which $880 million was held outside of the U.S. 
As of December 31, 2022, we had $599 million of cash and cash equivalents on hand, of which $122 million was held outside of the U.S. 
Our cash balance is intended to fund current maturities of long-term debt. We will continue to evaluate our cash position in light of future 
developments. 

In January 2024, we repaid €575 million ($630 million) of long-term debt. 

As of December 31, 2023, we had a $2.0 billion multi-year credit facility, which expires in April 2026. The credit facility has been 
established with a diverse syndicate of banks and supports our U.S. and Euro commercial paper programs. The maximum aggregate 
amount of commercial paper that may be issued under our U.S. commercial paper program and our Euro commercial paper program 
may not exceed $2.0 billion. At year end, we had no commercial paper outstanding under our U.S. program nor our Euro program. There 
were no borrowings under our credit facility as of December 31, 2023 or 2022. As of December 31, 2023, both programs were rated A-2 
by Standard & Poor’s, P-2 by Moody’s and F-1 by Fitch. 

Additionally, we have uncommitted credit lines with major international banks and financial institutions. These credit lines support our 
daily global funding needs, primarily our global cash pooling structures. As of December 31, 2023 we had $155 million of bank supported 
letters of credit, surety bonds and guarantees outstanding in support of our commercial business transactions. We do not have any other 
significant unconditional purchase obligations or commercial commitments. 

As of December 31, 2023, Standard & Poor’s, Fitch and Moody’s rated our long-term credit at A- (negative outlook), A- (stable outlook) 
and A3 (negative outlook), respectively. A reduction in our credit ratings could limit or preclude our ability to issue commercial paper 
under our current programs or could also adversely affect our ability to renew existing, or negotiate new, credit facilities in the future and 
could increase the cost of these facilities.  

As of December 31, 2023, we were in compliance with our debt covenants and other requirements of our credit agreements and 
indentures. 

A schedule of our various obligations as of December 31, 2023 are summarized in the following table:

*Interest on variable rate debt was calculated using the interest rate at year end 2023.

As of December 31, 2023, our gross liability for unrecognized tax benefits was $24 million. We are not able to reasonably estimate the 
amount by which the liability will increase or decrease over an extended period of time or whether a cash settlement of the liability will be 
required. Therefore, these amounts have been excluded from the schedule of contractual obligations. 

We do not have required minimum cash contribution obligations for our qualified pension plans in 2023. We are required to fund certain 
international pension benefit plans in accordance with local legal requirements. We estimate contributions to be made to our international 
plans will approximate $47 million in 2024. These amounts have been excluded from the schedule of contractual obligations. 

We lease certain sales and administrative office facilities, distribution centers, research and manufacturing facilities and other equipment 
under longer-term operating leases. Vehicle leases are generally shorter in duration. Vehicle leases have residual value requirements 
that have historically been satisfied primarily by the proceeds on the sale of the vehicles.

Market Risk 

We enter into contractual arrangements (derivatives) in the ordinary course of business to manage foreign currency exposure and 
interest rate risks. We do not enter into derivatives for speculative or trading purposes. Our use of derivatives is subject to internal 
policies that provide guidelines for control, counterparty risk, and ongoing monitoring and reporting, and is designed to reduce the 
volatility associated with movements in foreign exchange and interest rates on our income statement and cash flows. 

We enter into foreign currency forward contracts to hedge certain intercompany financial arrangements, and to hedge against the effect 
of exchange rate fluctuations on transactions related to cash flows denominated in currencies other than U.S. dollars. We use net 
investment hedges as hedging instruments to manage risks associated with our investments in foreign operations. As of December 31, 
2023, we had a total of €834 million senior notes designated as net investment hedges.  

We enter into cross-currency swap derivative contracts to hedge certain Euro denominated exposures from our investments in certain of 
its Euro denominated functional currency subsidiaries. We use net investment hedges as hedging instruments to manage risks 
associated with our investments in foreign operations. As of December 31, 2023, we had €625 million of cross-currency swap derivative 
contracts outstanding designated as a net investment hedge.  

We enter into cross-currency swap derivative contracts to hedge certain Chinese Yen (“CNY”) denominated exposures from our 
investments in certain CNY denominated functional currency subsidiaries. We use net investment hedges as hedging instruments to 
manage risks associated with our investments in foreign operations. As of December 31, 2023, we had CNH 2,192 million (CNH is the 
CNY traded in the offshore market) of cross-currency swap derivative contracts outstanding designated as a net investment hedge.  

We manage interest expense using a mix of fixed and floating rate debt. To help manage borrowing costs, we may enter into interest rate 
swap agreements. Under these arrangements, we agree to exchange, at specified intervals, the difference between fixed and floating 
interest amounts calculated by reference to an agreed-upon notional principal amount. As of December 31, 2023, we had $1,500 million 
of interest rate swaps outstanding. 

Refer to Note 8 for further information on our hedging activity. 

Based on a sensitivity analysis (assuming a 10% change in market rates) of our foreign exchange and interest rate derivatives and other 
financial instruments, changes in exchange rates or interest rates would increase/decrease our financial position and liquidity by 
approximately $169 million. The effect on our results of operations would be substantially offset by the impact of the hedged items. 

GLOBAL ECONOMIC AND POLITICAL ENVIRONMENT 

Global Economies 

Approximately half of our sales are outside of the U.S. Our international operations subject us to changes in economic conditions and 
foreign currency exchange rates as well as political uncertainty in some countries which could impact future operating results.  

Argentina and Turkey are classified as highly inflationary economies in accordance with U.S. GAAP, and the U.S. dollar is the functional 
currency for our subsidiaries in Argentina and Turkey. During 2023, sales in Argentina and Turkey represented less than 1% of our 
consolidated sales. Assets held in Argentina and Turkey at the end of 2023 represented less than 1% of our consolidated assets.  

In light of Russia’s invasion of Ukraine and the sanctions against Russia by the United States and other countries, we have made the 
determination that we will limit our Russian business to operations that are essential to life, providing minimal support for our healthcare, 
life sciences, food and beverage and certain water businesses. We may further narrow our presence in Russia depending on future 
developments. Our Russian and Ukraine operations represented approximately 1% of our 2023 consolidated net sales. We recorded 
charges of $1.4 million and $13.1 million in 2023 and 2022, respectively, primarily related to recoverability risk of certain assets in both 
Russia and Ukraine.

We provide these measures as additional information regarding our operating results. We use these non-GAAP measures internally to 
evaluate our performance and in making financial and operational decisions, including with respect to incentive compensation. We 
believe that our presentation of these measures provides investors with greater transparency with respect to our results of operations and 
that these measures are useful for period-to-period comparison of results. 

Our non-GAAP adjusted financial measure for net sales excludes 2021 Purolite sales. Our non-GAAP adjusted financial measures for 
cost of sales, gross margin, operating income, other (income) expense and interest expense exclude the impact of special (gains) and 
charges and (with the exception of other (income) expense) the 2021 impact of the Purolite transaction, and our non-GAAP measures for 
tax rate, net income attributable to Ecolab and diluted EPS further exclude the impact of discrete tax items. We include items within 
special (gains) and charges and discrete tax items that we believe can significantly affect the period-over-period assessment of operating 
results and not necessarily reflect costs and/or income associated with historical trends and future results. After tax special (gains) and 
charges are derived by applying the applicable local jurisdictional tax rate to the corresponding pre-tax special (gains) and charges. 

EBITDA is defined as the sum of net income including non-controlling interest, provision for income taxes, net interest expense, 
depreciation and amortization. EBITDA is used in our net debt to EBITDA ratio, which we view as important indicators of the operational 
and financial health of our organization.  

We evaluate the performance of our international operations based on fixed currency rates of foreign exchange. Fixed currency amounts 
included in this Form 10-K are based on translation into U.S. dollars at the fixed foreign currency exchange rates established by 
management at the beginning of 2023. We also provide our segment results based on public currency rates for informational purposes. 

Our reportable segments do not include the impact of intangible asset amortization from the Nalco and Purolite transactions or the impact 
of special (gains) and charges as these are not allocated to our reportable segments. 

Our non-GAAP financial measures for organic sales, organic operating income and organic operating income margin are at fixed 
currency and exclude the impact of special (gains) and charges, the results of our acquired businesses from the first twelve months post 
acquisition and the results of divested businesses from the twelve months prior to divestiture. As part of the separation of ChampionX in 
2020, we entered into a Master Cross Supply and Product Transfer agreement with ChampionX to provide, receive or transfer certain 
products for a period up to 36 months and for a small set of products with limited suppliers over the next few years. Sales of product to 
ChampionX under this agreement are recorded in product and equipment sales in the Corporate segment along with the related cost of 
sales. These transactions are removed from the consolidated results as part of the calculation of the impact of acquisitions and 
divestitures. 

These non-GAAP measures are not in accordance with, or an alternative to U.S. GAAP and may be different from non-GAAP measures 
used by other companies. Investors should not rely on any single financial measure when evaluating our business. We recommend that 
investors view these measures in conjunction with the U.S. GAAP measures included in this MD&A and we have provided reconciliations 
of reported U.S. GAAP amounts to the non-GAAP amounts in this MD&A.

REPORTS OF MANAGEMENT

To our Shareholders: 

Management’s Responsibility for Financial Statements 

Management is responsible for the integrity and objectivity of the consolidated financial statements. The statements have been prepared 
in accordance with accounting principles generally accepted in the United States of America and, accordingly, include certain amounts 
based on management’s best estimates and judgments. 

The Board of Directors, acting through its Audit Committee composed solely of independent directors, is responsible for determining that 
management fulfills its responsibilities in the preparation of financial statements and maintains internal control over financial reporting. 
The Audit Committee recommends to the Board of Directors the appointment of the Company’s independent registered public accounting 
firm, subject to ratification by the shareholders. It meets regularly with management, the internal auditors and the independent registered 
public accounting firm. 

The independent registered public accounting firm has audited the consolidated financial statements included in this annual report and 
have expressed their opinion regarding whether these consolidated financial statements present fairly in all material respects our 
financial position and results of operation and cash flows as stated in their report presented separately herein. 

Management’s Report on Internal Control Over Financial Reporting 

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in 
Exchange Act Rule 13a-15(f). Under the supervision and with the participation of management, including the principal executive officer 
and principal financial officer, an evaluation of the design and operating effectiveness of internal control over financial reporting was 
conducted based on the 2013 framework in Internal Control — Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission. Based on the evaluation under the framework in Internal Control — Integrated Framework, 
management concluded that internal control over financial reporting was effective as of December 31, 2023. 

The Company’s independent registered public accounting firm, PricewaterhouseCoopers LLP, has audited the effectiveness of the 
Company’s internal control over financial reporting as of December 31, 2023 as stated in their report which is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Shareholders of Ecolab Inc. 

Opinions on the Financial Statements and Internal Control over Financial Reporting 

We have audited the accompanying consolidated balance sheets of Ecolab Inc. and its subsidiaries (the “Company”) as of December 31, 
2023 and 2022, and the related consolidated statements of income, of comprehensive income, of equity and of cash flows for each of the 
three years in the period ended December 31, 2023, including the related notes (collectively referred to as the “consolidated financial 
statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2023, based on criteria 
established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (COSO).  

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the 
Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period 
ended December 31, 2023 in conformity with accounting principles generally accepted in the United States of America. Also in our 
opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, 
based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO. 

Basis for Opinions 

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over 
financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying 
Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express opinions on the Company’s 
consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public 
accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be 
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of 
the Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits 
to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to 
error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. 

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the 
consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures 
included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits 
also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall 
presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an 
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating 
the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other 
procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. 

Definition and Limitations of Internal Control over Financial Reporting 

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

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

Critical Audit Matters 

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements 
that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are 
material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The 
communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, 
and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the 
accounts or disclosures to which it relates. 

48 

Valuation of Certain U.S. Defined Benefit Pension Plan Obligations 

As described in Note 16 to the consolidated financial statements, the Company’s projected benefit obligations for U.S. pension plans was 
$1,859.5 million as of December 31, 2023, of which a majority relates to certain U.S. pension plans. The measurement of the Company’s 
pension benefit obligations are dependent on a variety of assumptions determined by management and used actuaries in their valuation 
method and calculations. The significant assumptions used in developing the required estimates of the projected benefit obligations are 
the discount rates, expected returns on assets, projected salary increases, and mortality tables. 

The principal considerations for our determination that performing procedures relating to the valuation of certain U.S. defined benefit 
pension plan obligations is a critical audit matter are (i) the significant judgment by management when developing the estimate of certain 
U.S. defined benefit pension plan obligations; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and 
evaluating management’s significant assumptions related to the discount rates and expected return on assets; and (iii) the audit effort 
involved the use of professionals with specialized skill and knowledge. 

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on 
the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s valuation 
of the defined benefit pension plan obligations, including controls over the valuation of the U.S. defined benefit pension plan obligations. 
These procedures also included, among others (i) testing management’s process for developing the estimate of certain U.S. defined 
benefit pension plan obligations; (ii) evaluating the appropriateness of the actuarial valuation method and calculations used by 
management; (iii) testing the completeness and accuracy of underlying data used in the actuarial valuation method and calculations; and 
(iv) evaluating the reasonableness of the significant assumptions used by management related to the discount rates and expected return
on assets. Professionals with specialized skill and knowledge were used to assist in evaluating (i) the appropriateness of the actuarial
valuation method and calculations and (ii) the reasonableness of the discount rates and expected return on assets assumptions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1. NATURE OF BUSINESS

Ecolab is a global leader in water, hygiene and infection prevention solutions and services that protect people and vital resources. The 
Company delivers comprehensive solutions, data-driven insights and personalized service to advance food safety, maintain clean and 
safe environments, optimize water and energy use and improve operational efficiencies and sustainability for customers in the food, 
healthcare, hospitality and industrial markets in more than 170 countries. 

The Company’s cleaning and sanitizing programs and products and pest elimination services support customers in the foodservice, food 
and beverage processing, hospitality, healthcare, government and education, retail, textile care and commercial facilities management 
sectors. The Company’s products and technologies are also used in water treatment, pollution control, energy conservation, refining, 
primary metals manufacturing, papermaking, mining and other industrial processes. 

In December 2021, the Company acquired Purolite for total consideration of $3.7 billion in cash, net of cash acquired. Purolite is a 
leading and fast-growing global provider of high-end ion exchange resins for the separation and purification of solutions, that is highly 
complementary to the Company’s current offering and critical to safe, high quality drug production and biopharma product purification in 
the life sciences industries. It also provides purification and separation solutions for critical industrial markets like microelectronics, 
nuclear power and food and beverage. Headquartered in King of Prussia, Pennsylvania, Purolite operates in more than 30 countries. 
Purolite is reported within the Company’s Life Sciences operating segment. 

The Company is aligned into three reportable segments: Global Industrial, Global Institutional & Specialty, and Global Healthcare & Life 
Sciences as discussed in Note 18 Operating Segments and Geographical Information. Operating segments that were not aggregated 
and do not exceed the quantitative criteria to be separately reported have been combined into Other.  

2. SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and all subsidiaries in which the Company has a controlling 
financial interest. Investments in companies, joint ventures or partnerships in which the Company does not have control but has the 
ability to exercise significant influence over operating and financial decisions, are reported using the equity method of accounting. The 
alternative method of accounting is used in circumstance where the Company’s investments in companies, joint ventures and 
partnerships neither provide it control or significant influence over the investee and for investments that do not have readily identifiable 
fair values. Investments accounted for under the alternative method are recorded at cost and adjusted for impairments, if any, or 
observable price changes of the same or similar securities issued by the investee. International subsidiaries are included in the financial 
statements on the basis of their U.S. GAAP November 30 fiscal year ends to facilitate the timely inclusion of such entities in the 
Company’s consolidated financial reporting. All intercompany transactions and profits are eliminated in consolidation. 

Use of Estimates 

The preparation of the Company’s financial statements requires management to make certain estimates and assumptions that affect the 
reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses 
during the reporting periods. Actual results could differ from these estimates. The Company’s critical accounting estimates include 
revenue recognition, litigation and environmental reserves, actuarially determined liabilities, income taxes, long-lived assets, intangible 
assets and goodwill. 

Foreign Currency Translation 

Financial position and reported results of operations of the Company’s non-U.S. dollar functional currency international subsidiaries are 
measured using local currencies as the functional currency. Assets and liabilities of these operations are translated at the exchange rates 
in effect at each fiscal year end. The translation adjustments related to assets and liabilities that arise from changes in exchange rates 
from period to period are included in accumulated other comprehensive income (loss) in shareholders’ equity. Income statement 
accounts are translated at average rates of exchange prevailing during the year. As discussed in Note 18 Operating Segments and 
Geographic Information, the Company evaluates its international operations based on fixed rates of exchange; however, changes in 
exchange rates from period to period impact the amount of reported income from consolidated operations.  

Concentration of Credit Risk 

Credit risk represents the accounting loss that would be recognized at the reporting date if counterparties failed to perform as contracted. 
The Company believes the likelihood of incurring material losses due to concentration of credit risk is minimal. The principal financial 
instruments subject to credit risk are as follows: 

55 

Cash and Cash Equivalents - The Company maintains cash deposits with major banks, which from time to time may exceed insured 
limits. The possibility of loss related to financial condition of major banks has been deemed minimal. Additionally, the Company’s 
investment policy limits exposure to concentrations of credit risk and changes in market conditions. 

Accounts Receivable - A large number of customers in diverse industries and geographies, as well as the practice of establishing 
reasonable credit lines, limits credit risk. Based on historical trends and experiences, the allowance for expected credit losses is 
adequate to cover expected credit risk losses. 

Foreign Currency and Interest Rate Contracts and Derivatives - Exposure to credit risk is limited by internal policies and active monitoring 
of counterparty risks. In addition, the Company uses a diversified group of major international banks and financial institutions as 
counterparties. The Company does not anticipate nonperformance by any of these counterparties. 

Cash and Cash Equivalents 

Cash equivalents include highly-liquid investments with a maturity of three months or less when purchased. 

Accounts Receivable and Allowance for Expected Credit Losses 

Accounts receivable are carried at the invoiced amounts, less an allowance for expected credit losses, and generally do not bear interest. 
The Company’s allowance for expected credit losses estimates the amount of expected future credit losses by analyzing accounts 
receivable balances by age and applying historical write-off and collection experience. The Company’s estimates separately consider 
macroeconomic trends, specific circumstances and credit conditions of customer receivables. Account balances are written off against 
the allowance when it is determined the receivable will not be recovered. 

The Company’s allowance for the expected return of products shipped and credits related to pricing or quantities shipped was $72 
million, $59 million, and $19 million as of December 31, 2023, 2022 and 2021, respectively. Returns and credit activity is recorded 
directly as a reduction to revenue. 

The following table summarizes the activity in the allowance for expected credit losses:

   (27.4)
 (3.2)
 $52.8 

(a) Other amounts are primarily the effects of changes in currency translations and acquired balances.

Inventory Valuations 

Inventories are valued at the lower of cost or net realizable value. Certain U.S. inventory costs are determined on a last-in, first-out 
(“LIFO”) basis. LIFO inventories represented 30% and 29% of consolidated inventories as of December 31, 2023 and 2022, respectively. 
All other inventory costs are determined using either the average cost or first-in, first-out (“FIFO”) methods. Inventory values at FIFO, as 
shown in Note 5, approximate replacement cost. 

Property, Plant and Equipment 

Property, plant and equipment assets are stated at cost. Merchandising and customer equipment consists principally of various 
dispensing systems for the Company’s cleaning and sanitizing products, warewashing machines and process control and monitoring 
equipment. Certain dispensing systems capitalized by the Company are accounted for on a mass asset basis, whereby equipment is 
capitalized and depreciated as a group and written off when fully depreciated. The Company capitalizes both internal and external costs 
to develop or purchase computer software. Costs incurred for data conversion, training and maintenance associated with capitalized 
software are expensed as incurred. Expenditures for major renewals and improvements, which significantly extend the useful lives of 
existing plant and equipment, are capitalized and depreciated. Expenditures for repairs and maintenance are charged to expense as 
incurred. Upon retirement or disposition of plant and equipment, the cost and related accumulated depreciation are removed from the 
accounts and any resulting gain or loss is recognized in income. 

Depreciation is charged to operations using the straight-line method over the assets’ estimated useful lives ranging from 5 to 40 years for 
buildings and leasehold improvements, 3 to 20 years for machinery and equipment, 3 to 20 years for merchandising and customer 
equipment and 3 to 7 years for capitalized software. The straight-line method of depreciation reflects an appropriate allocation of the cost 
of the assets to earnings in proportion to the amount of economic benefits obtained by the Company in each reporting period. 
Depreciation expense was $617 million, $619 million and $604 million for 2023, 2022 and 2021, respectively. 

56 

 
 
 
 
 
 
 
 
 
 
 
 
 
Goodwill and Other Intangible Assets 

Goodwill 

Goodwill arises from the Company’s acquisitions and represents the excess of the fair value of the purchase consideration exchanged 
over the fair value of net assets acquired. The Company’s reporting units are its ten operating segments. The Company assesses 
goodwill for impairment on an annual basis during the second quarter. If circumstances change or events occur that demonstrate it is 
more likely than not that the carrying amount of a reporting unit exceeds its fair value, the Company completes an interim goodwill 
impairment assessment of that reporting unit prior to the next annual assessment. If the results of an annual or interim goodwill 
impairment assessment demonstrate the carrying amount of a reporting unit is greater than its fair value, the Company will recognize an 
impairment loss for the amount by which the reporting unit’s carrying amount exceeds its fair value, but not to exceed the carrying 
amount of goodwill assigned to that reporting unit.  

During the second quarter of 2023, the Company completed its annual goodwill impairment assessment for its ten reporting units using 
discounted cash flow analyses that incorporated assumptions regarding future growth rates, terminal values and discount rates. The 
Company’s goodwill impairment assessments for 2023 indicated the estimated fair values of each of these ten reporting units exceeded 
the carrying amounts of the respective reporting unit by a significant margin. The Company evaluates the need to complete interim 
goodwill impairment assessments when significant events or changes in business circumstances indicate that it is more likely than not 
that the carrying amount of a reporting unit may be higher than its fair value. No events were noted during the second half of 2023 that 
required completion of an interim goodwill impairment assessment for any of our ten reporting units. There has been no impairment of 
goodwill in any of the periods presented.  

The changes in the carrying amount of goodwill for each of the Company’s reportable segments were as follows:

Other Intangible Assets 

The Nalco trade name is the Company’s only indefinite life intangible asset, which is tested for impairment on an annual basis during the 
second quarter. During the second quarter of 2023, the Company completed its annual impairment assessment of the Nalco trade name 
using the relief from royalty discounted cash flow method, which incorporates assumptions regarding future sales projections, royalty rate 
and discount rates. The Company’s Nalco trade name impairment assessment for 2023 indicated the estimated fair value of the Nalco 
trade name exceeded its $1.2 billion carrying amount by a significant margin. No events were noted during the second half of 2023 that 
required completion of an interim impairment assessment of our Nalco trade name. There has been no impairment of the Nalco trade 
name intangible asset since it was acquired. 

The Company’s intangible assets subject to amortization include customer relationships, trademarks, patents and other technology 
primarily acquired through business acquisitions. The fair value of intangible assets acquired in business acquisitions are estimated 
primarily using discounted cash flow valuation methods at the time of acquisition. Intangible assets are amortized on a straight-line basis 
over their estimated lives. The weighted-average useful life of amortizable intangible assets was 15 years as of December 31, 2023 and 
2022.

The weighted-average useful life by type of amortizable asset at December 31, 2023 were as follows: 

(years)

Patents 
Trademarks 
Other technology

The straight-line method of amortization reflects an appropriate allocation of the cost of the intangible assets to earnings in proportion to 
the amount of economic benefits obtained by the Company in each reporting period. The Company evaluates the remaining useful life of 
its intangible assets subject to amortization each reporting period to determine whether events and circumstances warrant a change to 
the estimated remaining period of amortization. If the estimate of an intangible asset’s remaining useful life is changed, the remaining 
carrying amount of the intangible asset will be amortized prospectively over the updated remaining useful life. Amortization expense 
related to other intangible assets during the last three years and future estimated amortization were as follows:

The Company reviews its long-lived and amortizable intangible assets for impairment when significant events or changes in business 
circumstances indicate that the carrying amount of the assets, or asset group to which it is assigned, may not be recoverable. Such 
circumstances may include a significant decrease in the market price of an asset or asset group, a significant adverse change in the 
manner in which the asset or asset group is being used or history of cash flow losses associated with the use of an asset or asset group. 
Impairment losses could occur when the carrying amount of an asset or asset group exceeds the anticipated future undiscounted cash 
flows expected to result from the use of the asset or asset group and its eventual disposition. The amount of the impairment loss to be 
recorded, if any, is calculated by the excess of the asset’s or asset group’s carrying value over its fair value.  

In addition, the Company periodically reassesses the estimated remaining useful lives of its long-lived assets. Changes to estimated 
useful lives would impact the amount of depreciation and amortization recorded in earnings. The Company has not experienced 
significant changes in the carrying amount or estimated remaining useful lives of its long-lived or amortizable intangible assets. 

Rental and Leases 

Lessee 

The Company determines whether a lease exists at the inception of the arrangement. In assessing whether a contract is or contains a 
lease, the Company evaluates whether the arrangement conveys the right to control the use of an identified asset for a period of time in 
exchange for consideration. The Company accounts for lease components separately from the nonlease components (e.g., common-
area maintenance costs, property taxes, parking, etc.). Operating leases are recorded in operating lease assets, other current liabilities 
and operating lease liabilities in the Consolidated Balance Sheets.  

Operating lease assets and operating lease liabilities are measured and recognized based on the present value of the future minimum 
lease payments over the estimated lease term at the lease commencement date. The Company uses the rate implicit in the lease when 
available or determinable. When the rate implicit in the lease is not determinable, the Company uses its incremental borrowing rate 
based on the information available at the lease commencement date to determine the present value of future payments. Lease expense 
for minimum lease payments is recognized on a straight-line basis over the lease term. Variable lease payments are not included in the 
lease liability and are recognized as incurred. The Company identified real estate, vehicles and other equipment as the primary classes 
of its leases. Certain leases with a similar class of underlying assets are accounted for as a portfolio of leases.  

The Company does not record operating lease assets or liabilities for leases with terms of twelve months or less. Those lease payments 
are recognized in the Consolidated Statements of Income over the lease term as incurred.  

Many of the Company’s leases include options to renew or cancel, which are at the Company’s sole discretion. Renewal terms can 
extend the lease term from one month to multiple years, whereas, cancellation terms can shorten the lease term by multiple years. The 
lease start date is the date when the leased asset is available for use and in possession of the Company. The lease end date, which 
includes any options to renew or cancel that are reasonably certain to be exercised, is based on the terms of the contract. The 
depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or 
purchase option reasonably certain of exercise. The Company’s lease agreements do not contain any material restrictive covenants. 

Lessor 

The Company accounts for lease and nonlease components separately. The nonlease components, such as product and service 
revenue, are accounted for under Topic 606 Revenue from Contracts with Customers, refer to Note 17 for more information. Revenue 
from leasing equipment is recognized on a straight-line basis over the life of the lease. Cost of sales includes the depreciation expense 
for assets under operating leases. The assets are depreciated over their estimated useful lives. Initial lease terms range from one year to 
five years and most leases include renewal options. 

Lease contracts convey the right for the customer to control the equipment for a period of time as defined by the contract. There are no 
options for the customer to purchase the equipment and therefore the equipment remains the property of the Company at the end of the 
lease term. Refer to Note 13 for additional information regarding rental and leases.  

58 

 
 
 
 
 
 
 
Income Taxes 

Income taxes are recognized during the period in which transactions enter into the determination of financial statement income, with 
deferred income taxes provided for the tax effect of temporary differences between the carrying amount of assets and liabilities and their 
tax bases. The Company records a valuation allowance to reduce its deferred tax assets when uncertainty regarding their realizability 
exists. Relevant factors in determining the realizability of deferred tax assets include historical results, sources of future taxable income, 
the expected timing of the reversal of temporary differences, tax planning strategies and the expiration dates of the various tax attributes. 
The Company records liabilities for unrecognized tax benefits in accordance with the U.S. GAAP recognition and measurement criteria 
guidance. The Company has elected the period cost method and considers the estimated global intangible low taxed income (“GILTI”) 
impact in tax expense. The Company recognizes interest and penalties related to unrecognized tax benefits in the income tax provision. 

Refer to Note 12 for additional information regarding income taxes. 

Share-Based Compensation 

The Company measures compensation expense for share-based awards at fair value at the date of grant and recognizes compensation 
expense over the service period for awards expected to vest. The majority of grants to retirement eligible recipients (age 55 with required 
years of service) are recorded to expense using the non-substantive vesting method and are fully expensed over a six-month period 
following the date of grant. In addition, the Company includes a forfeiture estimate in the amount of compensation expense being 
recognized based on an estimate of the number of outstanding awards expected to vest.  

All excess tax benefits or deficiencies are recognized as discrete income tax items on the Consolidated Statements of Income. The 
extent of excess tax benefits is subject to variation in stock price and stock option exercises. Refer to Note 11 for additional information 
regarding equity compensation plans. 

Restructuring Activities 

The Company’s restructuring activities are associated with plans to enhance its efficiency, effectiveness and sharpen its competitiveness. 
These restructuring plans include net costs associated with significant actions involving employee-related severance charges, contract 
termination costs and asset write-downs and disposals. Employee termination costs are largely based on policies and severance plans, 
and include personnel reductions and related costs for severance, benefits and outplacement services. These charges are reflected in 
the quarter in which the actions are probable and the amounts are estimable, which typically is when management approves the 
associated actions. Contract termination costs include charges to terminate leases prior to the end of their respective terms and other 
contract termination costs. Asset write-downs and disposals include leasehold improvement write-downs, other asset write-downs 
associated with combining operations and disposal of assets. Refer to Note 3 for additional information regarding restructuring activities. 

Revenue Recognition 

Revenue is measured as the amount of consideration expected to be received in exchange for transferring goods or providing service.  

Product and Sold Equipment 

Revenue from product and sold equipment is recognized when obligations under the terms of a contract with the customer are satisfied, 
which generally occurs with the transfer of the product or delivery of the equipment.  

Service and Lease Equipment 

Revenue from service and leased equipment is recognized when the services are provided, or the customer receives the benefit from the 
leased equipment, which is over time. Service revenue is recognized over time utilizing an input method and aligns with when the 
services are provided. Typically, revenue is recognized using costs incurred to date because the effort provided by the field selling and 
service organization represents services provided, which corresponds with the transfer of control. Revenue for leased equipment is 
accounted for under Topic 842 Leases and recognized on a straight-line basis over the length of the lease contract. 

59 

Other Considerations 

Contracts with customers may include multiple performance obligations. For contracts with multiple performance obligations, the 
consideration is allocated between products and services based on their stand-alone selling prices. Stand-alone selling prices are 
generally based on the prices charged to customers when the good or service is not bundled with other product or services or using an 
expected cost plus margin. Judgment is used in determining the amount of service that is embedded within the Company’s contracts, 
which is based on the amount of time spent on the performance obligation activities. The level of effort, including the estimated margin 
that would be charged, is used to determine the amount of service revenue. Depending on the terms of the contract, the Company may 
defer the recognition of revenue when a future performance obligation has not yet occurred. 

Taxes assessed by a governmental authority that are both imposed on, and concurrent with, a specific revenue-producing transaction, 
which are collected by the Company from a customer, are excluded from revenue. Shipping and handling costs associated with outbound 
freight are recognized in cost of sales when control over the product has transferred to the customer. 

Other estimates used in recognizing revenue include allocating variable consideration to customer programs and incentive offerings, 
including pricing arrangements, promotions and other volume-based incentives at the time the sale is recorded. These estimates are 
based primarily on historical experience and anticipated performance over the contract period. Based on the certainty in estimating these 
amounts, they are included in the transaction price of the contracts and the associated remaining performance obligations. The Company 
recognizes revenue when collection of the consideration expected to be received in exchange for transferring goods or providing services 
is probable. 

The Company’s revenue policies do not provide for general rights of return. Estimates used in recognizing revenue include the delay 
between the time that products are shipped and when they are received by customers, when title transfers and the amount of credit 
memos issued in subsequent periods. Depending on market conditions, the Company may increase customer incentive offerings, which 
could reduce gross profit margins over the term of the incentive. 

Earnings Per Common Share 

The difference in the weighted average common shares outstanding for calculating basic and diluted earnings attributable to Ecolab per 
common share is a result of the dilution associated with the Company’s equity compensation plans. As noted in the table below, certain 
stock options and units outstanding under these equity compensation plans were not included in the computation of diluted earnings 
attributable to Ecolab per common share because they would not have had a dilutive effect. 

The computations of the basic and diluted earnings attributable to Ecolab per share amounts were as follows:

Entities are required to 
apply the disclosure 
amendments on a 
retrospective basis to all 
periods presented. The 
Company is currently 
evaluating the impact of 
adoption. 

The amendments in this Update 
require that public business entities 
on an annual basis (1) disclose 
specific categories in the rate 
reconciliation and (2) provide 
additional information for 
reconciling items that meet a 
quantitative threshold. 

The amendments in this ASU are to 
improve the disclosures about 
reportable segments and add more 
detailed information about a 
reportable segment’s expenses. 
The amendments in the ASU 
require public entities to disclose on 
an annual and interim basis 
significant segment expenses that 
are regularly provided to the chief 
operating decision maker (“CODM”) 
and included within each reported 
measure of segment profit or loss, 
other segment items by reportable 
segment, the title and position of 
the CODM, and an explanation of 
how the CODM uses the reported 
measures of segment profit or loss 
in assessing segment performance 
and deciding how to allocate 
resources. The ASU does not 
change the definition of a segment, 
the method for determining 
segments, the criteria for 
aggregating operating segments 
into reportable segments, or the 
current specifically enumerated 
segment expenses that are 
required to be disclosed.

Restructuring Activities 

Restructuring activities are primarily related to the Combined Program which is described below. These activities have been included as 
a component of cost of sales, special (gains) and charges, other (income) expense and interest expense, net on the Consolidated 
Statements of Income. Restructuring liabilities have been classified as a component of other current and other noncurrent liabilities on 
the Consolidated Balance Sheets. 

Combined Program 

In November 2022 the Company approved a Europe cost savings program. In connection with these actions, the Company expected to 
incur pre-tax charges of $130 million ($110 million after tax). In February 2023, the Company expanded its previously announced Europe 
cost savings program to focus on its Institutional and Healthcare businesses in other regions. In connection with the expanded program 
(“Combined Program”), the Company expects to incur total pre-tax charges of $195 million ($150 million after tax). The Company expects 
that these restructuring charges will be completed by the end of 2024. Program actions include headcount reductions from terminations, 
not filling certain open positions, and facility closures. The Combined Program charges are expected to be primarily cash expenditures 
related to severance and asset disposals. 

In anticipation of this Combined Program, a limited number of actions were taken in the fourth quarter of 2022. As a result, the Company 
reclassified $19.3 million ($14.5 million after tax) from other restructuring to the Combined Program in the first quarter of 2023. 

In 2023 and 2022, the Company recorded total Combined Program restructuring charges of $77.7 million ($66.4 million after tax) and 
$67.2 million ($56.0 million after tax), respectively, primarily related to severance. The Company has recorded $164.2 million ($136.9 
million after tax) of cumulative charges under the Combined Plan. The net liability related to the Combined Program was $43.1 million 
and $62.0 million as of December 31, 2023 and 2022, respectively. The remaining liability is expected to be paid over a period of a few 
months to several quarters and will continue to be funded from operating activities. 

Restructuring activity related to the Combined Program since inception of the underlying actions includes the following:

Institutional Advancement Program 

The Company approved a restructuring plan in 2020 focused on the Institutional business (“the Institutional Plan”) which is intended to 
enhance the Company’s Institutional sales and service structure and allow the sales team to capture share and penetration while 
maximizing service effectiveness by leveraging the Company’s ongoing investments in digital technology. 

Certain activities contemplated in this Institutional Plan were previously approved in 2020 and included as part of Accelerate 2020. These 
activities were reclassified to the Institutional Plan. During 2023, 2022 and 2021, the Company recorded restructuring charges of $8.0 
million ($6.0 million after tax), $6.3 million ($4.8 million after tax) and $12.6 million ($10.2 million after tax), respectively, primarily related 
to severance, disposals of equipment and office closures. The restructuring activities were completed at the end of 2023, with total costs 
of $62.1 million ($47.4 million after tax). Net cash payments were $2.6 million and non-cash net charges were $6.8 million during 2023. 
There was no liability related to the Institutional Plan as of December 31, 2023 and $1.9 million as of December 31, 2022. 

Accelerate 2020 

During 2018, the Company formally commenced a restructuring plan, Accelerate 2020 (“the A2020 Plan”), to leverage technology and 
systems investments and organizational changes. The goals of the A2020 Plan were to further simplify and automate processes and 
tasks, reduce complexity and management layers, consolidate facilities and focus on key long-term growth areas by further leveraging 
technology and structural improvements. The Company recorded restructuring charges of $9.9 million ($8.4 million after tax) and $5.3 
million ($6.2 million after tax) in 2022 and 2021, respectively, primarily related to severance. The restructuring activities were completed 
at the end of 2022, with total costs of $254.4 million ($198.4 million after tax).  

Net cash payments were $13.2 million during 2023. The liability related to the A2020 Plan were $4.9 million and $18.1 million as of 
December 31, 2023 and 2022, respectively. The remaining liability is expected to be paid over a period of a few months to several 
quarters and will continue to be funded from operating activities. 

Other Restructuring Activities  

During 2022, and 2021, the Company recorded other restructuring charges of $23.8 million ($17.9 million after tax), and $18.7 million 
($17.0 million after tax), respectively, related to other immaterial restructuring activity. The charges are comprised primarily of severance 
and asset write-offs.  

The restructuring liability balance for all other restructuring plans excluding Combined Program, the A2020 Plan and the Institutional Plan 
was $3.3 million and $23.2 million as of December 31, 2023 and 2022, respectively. The decrease in liability was driven primarily by the 
reclass of $19.3 million from other restructuring to the Combined Program in the first quarter of 2023. The remaining liability is expected 
to be paid over a period of a few months to several quarters and will continue to be funded from operating activities. Cash payments 
during 2023 related to all other restructuring plans excluding the Combined Program, the A2020 Plan and Institutional Plan were $0.6 
million.

charges reported in interest expense in 2021. 

Russia/Ukraine 

In light of Russia’s invasion of Ukraine and the sanctions against Russia by the United States and other countries, the Company has 
made the determination that it will limit the Company’s Russian business to operations that are essential to life, providing minimal support 
for the Company’s healthcare, life sciences, food and beverage and certain water businesses. The Company incurred charges of $1.4 
million ($1.1 million after tax) and $13.1 million ($12.6 million after tax) during 2023 and 2022, respectively, primarily related to

4. ACQUISITIONS AND DISPOSITIONS 

Acquisitions 

The Company makes business acquisitions that align with its strategic business objectives. The assets and liabilities of acquired 
businesses are recorded in the Consolidated Balance Sheets based on estimates of the fair value of assets acquired, liabilities assumed 
and noncontrolling interests acquired as of the acquisition date. Goodwill is recognized in the amount that the purchase consideration 
paid exceeds the fair value of the net assets acquired. Purchase consideration includes both cash paid and the fair value of noncash 
consideration exchanged, including stock and/or contingent consideration exchanged, and is reduced by the amount of cash or cash 
equivalents acquired. Acquisitions during 2023, 2022 and 2021 were not significant to the Company’s consolidated financial statements; 
therefore, pro forma financial information is not presented.  

2023 Activity 

In November 2023, the Company acquired Flottec, LLC, a U.S.-based provider of flotation products and services for the mineral 
processing industry. The move will expand Nalco Water’s flotation offerings and its work to serve the industry from mine to metal. The 
acquisition became part of the Global Industrial reporting segment. The purchase accounting for this acquisition is preliminary and 
subject to change as the Company finalizes the valuation of intangible assets, income tax balances and working capital. The goodwill 
arising from the acquisition of Flottec, LLC is tax deductible.  

In May 2023, the Company acquired Chemlink Laboratories LLC, a U.S.-based producer of small format cleaning solutions. The 
Company made two other immaterial acquisitions during the second quarter of 2023. All three acquisitions became part of the Global 
Institutional & Specialty reporting segment. The purchase accounting for these acquisitions are preliminary and subject to change as the 
Company finalizes the valuation of intangible assets, income tax balances and working capital. The goodwill arising from the acquisition 
of Chemlink Laboratories LLC is tax deductible. 

2022 Activity 

No acquisitions occurred during 2022. 

2021 Activity 

Purolite Acquisition 

On December 1, 2021, the Company acquired Purolite for total consideration of $3,706 million in cash, net of cash acquired. Purolite is a 
US-based business that is a leading and fast-growing global provider of resins for the separation and purification of solutions that is 
highly complementary to the Company’s current offering and critical to safe, high quality drug production and biopharma product 
purification in the life sciences industries. It also provides purification and separation solutions for critical industrial markets like 
microelectronics, nuclear power and food and beverage. Prior to acquisition, Purolite prepared its consolidated financial statements 
pursuant to the requirements of UK GAAP.  

The Purolite acquisition has been accounted for as a business combination with the assets acquired and liabilities assumed recognized 
at fair value as of the acquisition date. The fair values of intangible assets acquired were estimated using discounted cash flow analyses 
appropriate in the circumstances for the nature of the assets being valued. The valuation models incorporated projections of future cash 
flows and other valuation assumptions. Significant inputs and assumptions used in the Company’s customer relationship intangible asset 
valuations include projected revenues, contributory asset charges, tax savings due to amortization, income tax rates, customer attrition 
rates and discount rates. Significant inputs and assumptions used in the Company’s tradename and acquired technology intangible asset 
valuations include projected revenues, future asset utilities, royalty rates, tax saving due to amortization, income tax rates and discount 
rates.

During 2022, the Company recorded purchase accounting adjustments associated with the finalization of the purchase accounting for its 
acquisition of Purolite. As a result of these purchase accounting adjustments, the Company made $7.2 million of acquisition-related 
payments, acquisition related net tangible assets decreased by $54.0 million, definite-lived intangible assets decreased by $185.4 million 
and goodwill increased by $246.6 million.

inventory of $122.4 million. Liabilities assumed primarily consist of deferred tax liabilities of $38.2 million and current liabilities of $77.6 
million. Identified intangible assets primarily consist of customer relationships, acquired technologies, and trade names and are being 
amortized over weighted average lives of 17, 14, and 5 years, respectively, with a weighted average life of 15 years.  

Goodwill of $2,260.6 million arising from the acquisition consists largely of the synergies and economies of scale expected through 
adding complementary geographies and innovative products to the Company’s Life Sciences businesses. Purolite became part of the 
Global Healthcare & Life Sciences reportable segment. Goodwill of $2,146.3 million is deductible for income tax purposes.

In November 2022, the Company issued $500 million in aggregate principal five year fixed rate notes with a coupon rate of 5.25% (“New 
5-Year Note”). The proceeds are intended to be used for general corporate purposes, which may include, without limitation, repayment of 
commercial paper borrowings or other indebtedness. The notes mature January 2028. 

The Company’s public notes may be redeemed by the Company at its option at redemption prices that include accrued and unpaid 
interest and a make-whole premium. Upon the occurrence of a change of control accompanied by a downgrade of the public notes below 
investment grade rating, within a specified time period, the Company would be required to offer to repurchase the public notes at a price 
equal to 101% of the aggregate principal amount thereof, plus any accrued and unpaid interest to the date of repurchase. The public 
notes are senior unsecured and unsubordinated obligations of the Company and rank equally with all other senior and unsubordinated 
indebtedness of the Company. 

In January 2024, the Company repaid €575 million ($630 million) of long-term debt. 

Covenants and Future Maturities 

The Company is in compliance with all covenants under the Company’s outstanding indebtedness at December 31, 2023. 

As of December 31, 2023, the aggregate annual maturities of long-term debt for the next five years were:

Interest expense generally includes the expense associated with the interest on the Company’s outstanding borrowings. Interest expense 
also includes the amortization of debt issuance costs and debt discounts, which are both recognized over the term of the related debt.  

During 2021, the Company issued, exchanged and retired certain long-term debt, incurring debt refinancing charges of $32.3 million 
($28.4 million after tax), which are included as a component of interest expense, net on the Consolidated Statements of Income.  

7. FAIR VALUE MEASUREMENTS 

The Company’s financial instruments include cash and cash equivalents, accounts receivable, accounts payable, contingent 
consideration obligations, commercial paper, notes payable, foreign currency forward contracts, interest rate swap agreements, cross-
currency swap derivative contracts and long-term debt. 

Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between 
market participants as of the measurement date. A hierarchy has been established for inputs used in measuring fair value that maximizes 
the use of observable inputs and minimizes the use of unobservable inputs by requiring the most observable inputs be used when 
available. The hierarchy is broken down into three levels: 

Level 1 - Inputs are quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities. 
Level 2 - Inputs include observable inputs other than quoted prices in active markets. 
Level 3 - Inputs are unobservable inputs for which there is little or no market data available. 

The carrying amount and the estimated fair value for assets and liabilities measured on a recurring basis were:

The carrying value of foreign currency forward contracts is at fair value, which is determined based on foreign currency exchange rates 
as of the balance sheet date and classified within Level 2. The carrying value of interest rate swap agreements is at fair value, which is 
determined based on current forward interest rates as of the balance sheet date and are classified within Level 2. The cross-currency 
swap derivative contracts are used to partially hedge the Company’s net investments in foreign operations against adverse movements 
in exchange rates between the U.S. dollar and the Euro and the U.S. dollar and CNH (CNH is the Chinese Yuan traded in the offshore 
market). The carrying value of the cross-currency swap derivative contracts is at fair value, which is determined based on the income 
approach with the relevant interest rates and foreign currency current exchange rates and forward curves as inputs as of the balance 
sheet date and are classified within Level 2. For purposes of fair value disclosure above, derivative values are presented gross. Further 
discussion of gross versus net presentation of the Company's derivatives within Note 8.

Contingent consideration obligations are recognized and measured at fair value at the acquisition date and thereafter until settlement or 
expiration. Contingent consideration is classified within Level 3 as the underlying fair value is determined using income-based valuation 
approaches appropriate for the terms and conditions of each respective contingent consideration. The consideration expected to be 
transferred is based on the Company’s expectations of various financial measures. The ultimate payment of contingent consideration 
could deviate from current estimates based on the actual results of these financial measures. Contingent consideration during 2023, 
2022 and 2021 were not significant to the Company’s consolidated financial statements.  

The carrying values of accounts receivable, accounts payable, cash and cash equivalents, commercial paper and notes payable 
approximate fair value because of their short maturities, and as such are classified within Level 1. 

The fair value of long-term debt is based on quoted market prices for the same or similar debt instruments (classified as Level 2). The 
carrying amount, which includes adjustments related to the impact of interest rate swap agreements, premiums and discounts, and 
deferred debt issuance costs, and the estimated fair value of long-term debt, including current maturities, held by the Company was:

The Company uses foreign currency forward contracts, interest rate swap agreements, cross-currency swap derivative contracts and 
foreign currency debt to manage risks associated with foreign currency exchange rates, interest rates and net investments in foreign 
operations. The Company does not hold derivative financial instruments of a speculative nature or for trading purposes. The Company 
records derivatives as assets and liabilities in the Consolidated Balance Sheets at fair value. Changes in fair value are recognized 
immediately in earnings unless the derivative qualifies and is designated as a hedge. Cash flows from derivatives are classified in the 
Consolidated Statements of Cash Flows in the same category as the cash flows from the items subject to designated hedge or 
undesignated (economic) hedge relationships. The Company evaluates hedge effectiveness at inception and on an ongoing basis. If a 
derivative is no longer expected to be effective, hedge accounting is discontinued.  

The Company is exposed to credit risk in the event of nonperformance of counterparties for foreign currency forward exchange contracts 
and interest rate swap agreements. The Company monitors its exposure to credit risk by using credit approvals and credit limits and by 
selecting major global banks and financial institutions as counterparties. The Company does not anticipate nonperformance by any of 
these counterparties, and therefore, recording a valuation allowance against the Company’s derivative balance is not considered 
necessary. 

Derivative Positions Summary 

Certain of the Company’s derivative transactions are subject to master netting arrangements that allow the Company to net settle 
contracts with the same counterparties. These arrangements generally do not call for collateral and as of the applicable dates presented 
in the following table, no cash collateral had been received or pledged related to the underlying derivatives. 

The respective net amounts are included in other current assets, other assets, other current liabilities and other liabilities on the 
Consolidated Balance Sheets.

The Company utilizes foreign currency forward contracts to hedge the effect of foreign currency exchange rate fluctuations on forecasted 
foreign currency transactions, including inventory purchases and intercompany royalty, intercompany loans, management fee and other 
payments. These forward contracts are designated as cash flow hedges. The changes in fair value of these contracts are recorded in 
accumulated other comprehensive income (loss) (“AOCI”) until the hedged items affect earnings, at which time the gain or loss is 
reclassified into the same line item in the Consolidated Statements of Income as the underlying exposure being hedged. Cash flow 
hedged transactions impacting AOCI are forecasted to occur within the next year. For forward contracts designated as hedges of foreign 
currency exchange rate risk associated with forecasted foreign currency transactions, the Company excludes the changes in fair value 
attributable to time value from the assessment of hedge effectiveness. The initial value of the excluded component (i.e., the forward 
points) is amortized on a straight-line basis over the life of the hedging instrument and recognized in the same line item in the 
Consolidated Statements of Income as the underlying exposure being hedged for intercompany loans. For all other cash flow hedge 
types, the forward points are mark-to-market monthly and recognized in the same line item in the Consolidated Statements of Income as 
the underlying exposure being hedged. The difference between fair value changes of the excluded component and the amount amortized 
in the Consolidated Statements of Income is recorded in AOCI.  

Fair Value Hedges 

The Company manages interest expense using a mix of fixed and floating rate debt. To help manage exposure to interest rate 
movements and to reduce borrowing costs, the Company may enter into interest rate swaps under which the Company agrees to 
exchange, at specified intervals, the difference between fixed and floating interest amounts calculated by reference to an agreed upon 
notional principal amount. The mark-to-market of these fair value hedges is recorded as gains or losses in interest (income) expense and 
is offset by the gain or loss of the underlying debt instrument, which also is recorded in interest (income) expense. These fair value 
hedges are highly effective and thus, there is no impact on earnings due to hedge ineffectiveness. 

In aggregate, the Company has entered into a series of interest rate swap agreements to convert $1.5 billion of its debt from a fixed 
interest rate to a floating interest rate. The fixed interest rates range from 1.3% to 4.8% and mature between 2026 and 2031. These 
interest rate swap agreements are designated as fair value hedges. 

The following amounts were recorded in the Consolidated Balance Sheets related to cumulative basis adjustments for fair value hedges 
as of December 31 2023 and 2022:

In November 2023, the Company elected to de-designate as a net investment hedge €316 million of its Euro debt maturing on January 
15, 2024. The Company designates its remaining outstanding €834 million ($908 million as of year-end 2023) senior notes (“Euronotes”) 
and related accrued interest as a hedge of its Euro denominated exposures from the Company’s investments in certain of its Euro 
denominated functional currency subsidiaries.  

The Company entered into a series of Euro cross-currency swap derivative contracts maturing in 2026 and 2030. These cross-currency 
swap derivative contracts are designated as net investment hedges of the Company’s Euro denominated exposures from the Company’s 
investments in certain of its Euro denominated functional currency subsidiaries. The cross-currency swap derivative contracts exchange 
fixed-rate payments in one currency for fixed-rate payments in another currency. As of December 31, 2023, the Company had a €625 
million ($690 million) cross-currency swap derivative contracts outstanding as a hedge of the Company’s net investment in foreign 
operations. The changes in the spot rate of these instruments are recorded in AOCI in stockholders’ equity, partially offsetting the foreign 
currency translation adjustment of the Company’s related net investment that is also recorded in AOCI. Any ineffective portions of net 
investment hedges are reclassified from AOCI into earnings during the period of change. The interest income or expense from these 
swaps are recorded in interest expense on the accompanying Consolidated Statements of Income consistent with the classification of 
interest expense attributable to the underlying debt.

In August and October of 2023, the Company entered into CNH cross-currency swap derivative contracts with a notional amount of CNH 
1,094 million and CNH 1,098 million, respectively, both maturing in 2032. The cross-currency swap derivative contracts are designated 
as net investment hedges of its Chinese Yuan (“CNY”) denominated exposures from the Company’s investments in certain CNY 
denominated functional currency subsidiaries. The cross-currency swap derivative contracts exchange fixed-rate payments in USD for 
fixed-rate payments in CNH. As of December 31, 2023, the Company had in aggregate, CNH 2,192 million ($308 million) cross-currency 
swap derivative contracts outstanding as a hedge of the Company’s net investment in foreign operations. The changes in the spot rate of 
these instruments are recorded in AOCI in stockholders’ equity, partially offsetting the foreign currency translation adjustment of the 
Company’s related net investment that is also recorded in AOCI. The interest income or expense from these swaps is recorded in 
interest expense on the accompanying Consolidated Statements of Income consistent with the classification of interest expense 
attributable to the underlying debt. 

The revaluation gains and losses on the Euronotes and cross-currency swap derivative contracts, which are designated and effective as 
hedges of the Company’s net investments, have been included as a component of the cumulative translation adjustment account, and

Derivatives Not Designated as Hedging Instruments 

The Company also uses foreign currency forward contracts to offset its exposure to the change in value of certain foreign currency 
denominated assets and liabilities held at foreign subsidiaries, primarily receivables and payables, which are remeasured at the end of 
each period. Although the contracts are effective economic hedges, they are not designated as accounting hedges. Therefore, changes 
in the value of these derivatives are recognized immediately in earnings, thereby offsetting the current earnings effect of the related 
foreign currency denominated assets and liabilities.

Authorized common stock, par value $1.00 per share, was 800 million shares at December 31, 2023, 2022 and 2021. Treasury stock is 
stated at cost. Dividends declared per share of common stock were $2.16 for 2023, $2.06 for 2022 and $1.95 for 2021. 

The Company has 15 million shares, without par value, of authorized but unissued and undesignated preferred stock.  

Share Repurchase Authorization 

In February 2015 and November 2022, the Company’s Board of Directors authorized the repurchase of up to 20,000,000 and 
10,000,000, respectively, additional shares of its common stock, including shares to be repurchased under Rule 10b5-1. As of December 
31, 2023, 12,917,097 shares remained to be repurchased under the Company’s repurchase authorization. The Company intends to 
repurchase all shares under its authorization, for which no expiration date has been established, in open market or privately negotiated 
transactions, subject to market conditions. 

Share Repurchases 

During 2023, 2022 and 2021, the Company reacquired 83,674, 3,038,107 and 502,132 shares, respectively, of its common stock, of 
which 0, 2,933,090 and 389,759, respectively, related to share repurchases through open market or private purchases, and 83,674, 
105,017 and 112,373, respectively, related to shares withheld for taxes on exercise of stock options and vesting of stock awards and 
units.  

The Inflation Reduction Act (“IRA”) was signed into U.S. law on August 16, 2022 and is effective January 1, 2023. The IRA includes an 
excise tax on the repurchase of corporate stock. The Company does not anticipate the excise tax to have a material impact on the 
Company’s financial statements.

11. EQUITY COMPENSATION PLANS 

The Company’s equity compensation plans provide for grants of stock options, performance-based restricted stock units (“PBRSUs”) and 
non-performance-based restricted stock units (“RSUs”) and restricted stock awards (“RSAs”). Common shares available for grant as of 
December 31, 2023, 2022 and 2021 were 18,840,265, 5,475,903 and 7,544,458, respectively. The Company generally issues authorized 
but previously unissued shares to satisfy stock option exercises and stock award vesting.  

The Company’s annual long-term incentive share-based compensation program is made up of 40% stock options and 60% PBRSUs for 
2023 and 50% stock options and 50% PBRSUs for 2022 and 2021. The Company also periodically grants RSUs. Total compensation 
expense related to all share-based compensation plans was $95.1 million ($81.4 million net of tax benefit), $87.8 million ($74.8 million 
net of tax benefit) and $89.5 million ($75.4 million net of tax benefit) for 2023, 2022 and 2021, respectively. As of December 31, 2023, 
there was $174.0 million of total measured but unrecognized compensation expense related to non-vested share-based compensation 
arrangements granted under all of the Company’s plans. That cost is expected to be recognized over a weighted-average period of 2.2 
years. 

Stock Options 

Stock options are granted to purchase shares of the Company’s stock at the average daily share price on the date of grant. These 
options generally expire within ten years from the grant date. The Company generally recognizes compensation expense for these 
awards on a straight-line basis over the three year vesting period. Stock option grants to retirement eligible recipients are attributed to 
expense using the non-substantive vesting method.

The total aggregate intrinsic value of options (the amount by which the stock price exceeded the exercise price of the option on the date 
of exercise) that were exercised during 2023, 2022 and 2021 was $47.7 million, $21.0 million and $148.1 million, respectively. 

The total aggregate intrinsic value of options outstanding as of December 31, 2023 was $244.4 million, with a corresponding weighted-
average remaining contractual life of 6.3 years. The total aggregate intrinsic value of options exercisable as of December 31, 2023 was 
$199.6 million, with a corresponding weighted-average remaining contractual life of 5.3 years. The total aggregate intrinsic value of 
options vested and expected to vest as of December 31, 2023 was $242.5 million, with a corresponding weighted-average remaining 
contractual life of 6.3 years. 

The lattice (binomial) option-pricing model is used to estimate the fair value of options at grant date. The Company’s primary employee 
option grant occurs during the fourth quarter. The weighted-average grant-date fair value of options granted and the significant 
assumptions used in determining the underlying fair value of each option grant, on the date of grant were as follows:

The risk-free rate of return is determined based on a yield curve of U.S. treasury rates from one month to ten years and a period 
commensurate with the expected life of the options granted. Expected volatility is established based on historical volatility of the 
Company’s stock price. The expected dividend yield is determined based on the Company’s annual dividend amount as a percentage of 
the average stock price at the time of the grant.

PBRSUs, RSUs and RSAs 

The expense associated with PBRSUs is based on the average of the high and low share price of the Company’s common stock on the 
date of grant, adjusted for the absence of future dividends. The awards vest based on the Company achieving a defined performance 
target and with continued service for a three year period. Upon vesting, the Company issues shares of its common stock such that one 
award unit equals one share of common stock. The Company assesses the probability of achieving the performance target and 
recognizes expense over the three year vesting period when it is probable the performance target will be met. PBRSU awards granted to 
retirement eligible recipients are attributed to expense using the non-substantive vesting method. The awards are generally subject to 
forfeiture in the event of termination of employment. 

The expense associated with shares of non-performance based RSUs and RSAs is based on the average of the high and low share 
price of the Company’s common stock on the date of grant, adjusted for the absence of future dividends and is amortized on a straight-
line basis over the periods during which the restrictions lapse. The Company currently has RSUs that vest over periods between 24 and 
60 months. The awards are generally subject to forfeiture in the event of termination of employment.

Presentation of prior year amounts relating to goodwill and intangible assets are now presented separately and have been reclassified to 
conform with the current year presentation. These reclassifications had no effect on the reported results of operations. 

As of December 31, 2023 the Company has tax effected federal, state and international net operating loss carryforwards of $0.2 million, 
$16.2 million and $40.9 million, respectively, and a tax effected federal tax capital loss carryforward of $3.6 million which will be available 
to offset future taxable income. The federal and state loss carryforwards of $16.4 million expire from 2024 to 2044. The international loss 
carryforwards of $14.1 million expire from 2024 to 2043 and $26.8 million have no expiration. The federal capital loss carryforwards of 
$3.6 million expire in 2025. The tax loss carryforwards expiring in 2024 are not material.  

Additionally, the Company has $83.7 million of net credit carryforwards that are primarily related to U.S. foreign tax credits and various 
state credits. The U.S. foreign tax credit carryforwards of $74.7 million expire from 2030 to 2033. Other state and international credit 
carryforwards will expire from 2024 to 2038. The tax credit carryforwards expiring in 2024 are not material.  

The Company has valuation allowances on certain deferred tax assets of $65.7 million and $65.2 million at December 31, 2023 and 
2022, respectively. The increase in valuation allowance from year end 2022 to year end 2023 was primarily due to U.S. state tax 
attributes, foreign net operating losses and other deferred tax assets. 

In connection with the implementation of Organization for Economic Co-operation and Development (“OECD”) global minimum tax 
initiative known as Pillar Two, any existing deferred taxes not disclosed in the Company’s 2023 financial statements will not be available 
in the future to reduce tax otherwise due under Pillar Two. Accordingly, the Company is disclosing the existence of gross tax loss 
carryforwards in Luxembourg of $1.3 billion. The losses are determined to have a remote possibility of realization and, therefore, are not 
reported in the table above. 

The Company obtained tax benefits from a tax holiday in the Dominican Republic. The Company received a permit of operation, which 
expires in April 2036, from the National Council of Free Zones of Exportation for the Dominican Republic. Companies operating under the 
Free Zones are not subject to income tax in the Dominican Republic on export income. The tax reduction as the result of the tax holiday 
for 2023 was $6.6 million ($0.02 per diluted share), 2022 was $5.8 million ($0.02 per diluted share) and 2021 was $2.9 million ($0.01 per 
diluted share).

The change in the Company’s effective income tax rate includes the tax impact of special (gains) and charges and discrete tax items, 
which have impacted the comparability of the Company’s historical effective income tax rates, as amounts included in special (gains) and 
charges are derived from tax jurisdictions with rates that vary from the statutory U.S. rate, and discrete tax items are not necessarily 
consistent across periods. The tax impact of special (gains) and charges and discrete tax items will likely continue to impact 
comparability of the Company’s effective income tax rate in the future.  

The Company’s 2023 effective tax rate of 20.6% includes $24.7 million of net tax benefits on special (gains) and charges, and net tax 
expense of $11.2 million associated with discrete items. The net discrete tax expense was primarily related to the filing of federal, state 
and foreign tax returns and other income tax adjustments including the impact of changes in tax laws, audit settlements, share-based 
compensation excess tax benefit and other changes in estimates.  

The Company’s 2022 effective tax rate of 17.5% includes $53.7 million of net tax benefits on special (gains) and charges, and net tax 
benefit of $11.8 million associated with discrete items. Discrete items included a deferred tax benefits of $14.6 million associated with 
utilization of tax attributes as a result of legal entity rationalization and share-based compensation excess tax benefits of $6.0 million. The 
remaining discrete tax expense of $8.8 million was primarily related to the filing of federal, state and foreign tax returns and other income 
tax adjustments including the impact of changes in tax laws, audit settlements and other changes in estimates.  

The Company’s 2021 effective tax rate of 19.1% includes $53.3 million of net tax benefits on special (gains) and charges, and net tax 
expense of $5.8 million associated with discrete items. During 2021, the Company recorded a discrete tax benefit of $29.1 million related 
to share-based compensation excess tax benefits. Additionally, the Company recorded $34.9 million discrete tax charges including a 
non-cash deferred tax charge of $25.1 million associated with transferring certain intangible property between affiliates. The remaining 
$9.8 million tax expense primarily related to the filing of federal, state and foreign tax returns and other income tax adjustments including 
the impact of changes in tax laws, audit settlements and other changes in estimates.  

A deferred tax liability of $2.8 million is recorded as of December 31, 2023 related to deferred tax liabilities on unremitted earnings, which 
are not permanently reinvested. The Company otherwise continues to assert permanent reinvestment of the undistributed earnings of 
international affiliates unless the earnings can be remitted in a net income tax benefit or tax-neutral manner. If there are policy changes, 
the Company would record the applicable taxes in the period of change. Due to the complexity of the legal entity structure, the number of 
legal entities and jurisdictions involved, and the complexity of the laws and regulations, the Company believes it is not practicable to 
estimate the amount of additional taxes which may be payable upon distribution of these undistributed earnings. Accordingly, no deferred 
taxes have been provided for withholding taxes or other taxes on permanently reinvested earnings.

The total amount of unrecognized tax benefits, if recognized would affect the effective tax rate by $21.6 million as of December 31, 2023, 
$23.1 million as of December 31, 2022 and $22.8 million as of December 31, 2021. 

The Company files U.S. federal income tax returns and income tax returns in various U.S. state and non- U.S. jurisdictions. With few 
exceptions, the Company is no longer subject to state and foreign income tax examinations by tax authorities for years before 2017. The 
IRS has completed examinations of the Company’s U.S. federal income tax returns through 2016, and the years 2017 through 2020 are 
currently under audit. In addition to the U.S. federal examination, there is ongoing audit activity in several U.S. state and foreign

jurisdictions. The Company anticipates changes to unrecognized tax benefits due to closing of various audits and statutes closing on 
years mentioned above. The Company does not believe these changes will result in a material impact during the next twelve months. 
Decreases in the Company’s gross liability could result in offsets to other balance sheet accounts, cash payments, and adjustments to 
tax expense. The occurrence of these events and/or other events not included above within the next twelve months could change 
depending on a variety of factors. 

The Company recognizes interest and penalties related to unrecognized tax benefits in its provision for income taxes. The Company had 
$4.0 million, $4.0 million and $3.2 million of accrued interest, including minor amounts for penalties, at December 31, 2023, 2022 and 
2021, respectively. 

13. RENTALS AND LEASES 

Lessee 

The Company leases sales and administrative office facilities, distribution centers, research and manufacturing facilities, as well as 
vehicles and other equipment under operating leases. Certain of the Company’s lease arrangements are finance leases, which are 
immaterial individually and in the aggregate.

The Company leases warewashing and water treatment equipment to customers under operating leases.  

Gross assets under operating leases recorded in Property, plant and equipment, net is $1,397.5 million and $1,288.3 million, and related 
accumulated depreciation is $878.9 million and $811.2 million, as of December 31, 2023 and 2022, respectively.  

The Company’s operating lease revenue was as follows: 
(millions)

The Company mitigates the risk of residual value subsequent to the lease term by redeploying assets. As such, the Company expects to 
receive revenue from the operating lease assets through the remaining useful life and therefore subsequent to the initial contract 
termination date. 

14. RESEARCH AND DEVELOPMENT EXPENDITURES 

Research expenditures that relate to the development of new products and processes, including significant improvements and 
refinements to existing products, are expensed as incurred. Such costs were $192 million in 2023, $190 million in 2022 and $186 million 
in 2021. The Company did not participate in any material customer sponsored research during any of the years. 

15. COMMITMENTS AND CONTINGENCIES 

The Company is subject to various claims and contingencies related to, among other things, workers’ compensation, general liability 
(including product liability), automobile claims, health care claims, environmental matters and lawsuits. The Company is also subject to 
various claims and contingencies related to income taxes, which are discussed in Note 12. The Company also has contractual 
obligations including lease commitments, which are discussed in Note 13. 

The Company records liabilities when a contingent loss is probable and can be reasonably estimated. If the reasonable estimate of a 
probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when no amount within 
the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is not probable or 
the amount is not estimable, or both, if there is a reasonable possibility that a material loss may have been incurred.  

Insurance 

Globally, the Company has insurance policies with varying deductible levels for property and casualty losses. The Company is insured 
for losses in excess of these deductibles, subject to policy terms and conditions and has recorded both a liability and an offsetting 
receivable for amounts in excess of these deductibles. The Company is self-insured for health care claims for eligible participating 
employees, subject to certain deductibles and limitations. The Company determines its liabilities for claims on an actuarial basis. 

Litigation and Environmental Matters  

The Company and certain subsidiaries are party to various lawsuits, claims and environmental actions that have arisen in the ordinary 
course of business. These include from time to time antitrust, employment, commercial, patent infringement, tort, product liability and 
wage hour lawsuits, as well as possible obligations to investigate and mitigate the effects on the environment of the disposal or release of 
certain chemical substances at various sites, such as Superfund sites and other operating or closed facilities. The Company has 
established accruals for certain lawsuits, claims and environmental matters. The Company currently believes that there is not a 
reasonably possible risk of material loss in excess of the amounts accrued related to these legal matters. Because litigation is inherently 
uncertain, and unfavorable rulings or developments could occur, there can be no certainty that the Company may not ultimately incur 
charges in excess of recorded liabilities. A future adverse ruling, settlement or unfavorable development could result in future charges 
that could have a material adverse effect on the Company’s results of operations or cash flows in the period in which they are recorded.

effect on the Company’s consolidated financial position. 

TPC Group Litigation 

On November 27, 2019, a Butadiene production plant owned and operated by TPC Group, Inc. (“TPC”) in Port Neches, Texas, 
experienced an explosion and fire that resulted in personal injuries, the release of chemical fumes and extensive property damage to the 
plant and surrounding areas in and near Port Neches, Texas. 

Nalco Company LLC, a subsidiary of Ecolab, supplied process chemicals to TPC used in TPC’s production processes. Nalco did not 
operate, manage, maintain or control any aspect of TPC’s plant operations. 

In connection with its provision of process chemicals to TPC, Nalco has been named in numerous lawsuits stemming from the plant 
explosion. Nalco has been named a defendant, along with TPC and other defendants, in multi-district litigation (“MDL”) proceedings 
pending in Orange County, Texas, alleging among other things claims for personal injury, property damage and business losses (In re 
TPC Group Litigation – A2020-0236-MDL, Orange County, Texas). In addition, numerous other lawsuits have been filed against Nalco, 
including TPC Group v. Nalco, E0208239, Jefferson County, Texas, a subrogation claim by TPC’s insurers seeking reimbursement for 
property damage losses. Over 5,000 plaintiffs (including the subrogation matter) currently have asserted claims against Nalco. 

All of these cases make similar allegations and seek damages for personal injury, property damage, business losses and other damages, 
including exemplary damages. The Company expects all these cases will be consolidated for pretrial purposes into the Orange County 
MDL referenced above. Due to the large number of plaintiffs, the early stage of the litigation and the fact that many of the claims do not 
specify an amount of damages, any estimate of any loss or range of losses cannot be made at this time. 

On June 1, 2022, TPC and seven of its affiliated companies filed for bankruptcy under Chapter 11 (Case No. 22-10493-CTG, United 
States Bankruptcy Court for the District of Delaware). In connection with the bankruptcy cases, TPC disclosed an estimated range of its 
liability related to the Port Neches incident to individuals and homeowners (including subrogation claims) of approximately $152 million to 
$520 million. As part of their bankruptcy plan, TPC and its affiliates announced a settlement which allows the MDL plaintiffs a $500 
million claim solely for purposes of claim allowance in the chapter 11 case and distribution of value pursuant to TPC’s bankruptcy plan. 
Other key terms of the settlement between TPC and the MDL plaintiffs include the establishment of a settlement trust for the benefit of 
certain general unsecured creditors, which is funded with $30 million and the assignment of TPC’s claims and causes of action, if any, 
against certain third parties, including Nalco, related to the TPC plant explosion. As part of the bankruptcy process, TPC and its debtor 
affiliates received a discharge of all MDL related claims, as did certain non-debtor affiliates to the extent third parties did not opt out of the 
non-debtor releases. Nalco opted out of these releases, preserving any direct causes of action it may have against non-debtors. 
Furthermore, the allowance of the $500 million claim should have no effect on any claims or defenses asserted against or by Nalco in the 
MDL litigation. On December 1, 2022, the bankruptcy court confirmed the TPC bankruptcy plan, including the approval of the settlement 
and establishment of the aforementioned settlement trust. On December 16, 2022, the TPC bankruptcy plan went effective. 

The Company believes the claims asserted against Nalco in the lawsuits stemming from the TPC plant explosion are without merit and 
intends to defend the claims vigorously. The Company also believes any potential loss should be covered by insurance subject to 
deductibles. However, the Company cannot predict the outcome of these lawsuits, the involvement the Company might have in these 
matters in the future or the potential for future litigation. 

Environmental Matters 

The Company is currently participating in environmental assessments and remediation at approximately 25 locations, the majority of 
which are in the U.S., and environmental liabilities have been accrued reflecting management’s best estimate of future costs. Potential 
insurance reimbursements are not anticipated in the Company’s accruals for environmental liabilities. 

16. RETIREMENT PLANS 

Pension and Postretirement Health Care Benefits Plans 

The Company has a non-contributory, qualified, defined benefit pension plan covering the majority of its U.S. employees. The Company 
also has U.S. non-contributory, non-qualified, defined benefit pension plans, which provide for benefits to employees in excess of limits 
permitted under its pension plans. The U.S. non-qualified plans are not funded and the recorded benefit obligations for the non-qualified 
plans were $87 million and $86 million at December 31, 2023 and 2022, respectively. The measurement date used for determining the 
U.S. pension plan assets and obligations is December 31.  

Various international subsidiaries have defined benefit pension plans. International plans are funded based on local country 
requirements. The measurement date used for determining the international pension plan assets and obligations is November 30, the 
fiscal year end of the Company’s international subsidiaries. 

The Company provides postretirement health care and life insurance benefits to certain U.S. employees and retirees. The U.S. 
postretirement health care plans are contributory based on years of service and choice of coverage (family or single), with retiree 
contributions adjusted annually. The Company also maintains several U.S. postretirement life insurance plans. The measurement date 
used to determine the U.S. postretirement health care and life insurance plan assets and obligations is December 31. Certain employees 

81 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
outside the U.S. are covered under government-sponsored programs, which are not required to be fully funded. The expense and 
obligation for providing international postretirement health care benefits are not significant.

These plans include the U.S. non-qualified pension plans which are not funded as well as various international pension plans which are 
funded consistent with local practices and requirements.  

For the year ended December 31, 2023, the year-over-year decrease in the Company's consolidated net benefit obligations was due to 
an increase in pension plan assets, partially offset by a smaller increase in pension plan liabilities. Pension liabilities increased on a 
global basis primarily due to decreases in pension discount rates for U.S. plans, partially offset by increases in pension discount rates for 
international plans. The Company's pension discount rates are largely determined based on observable yields of investment grade 
corporate bonds or government issued debt-securities. The Company's pension plan assets are reported at fair value. The fair value of 
the Company's pension assets increased on a global basis primarily due to higher returns on the Company's equity and fixed income 
investments compared to prior year. 

For the year ended December 31, 2022, the year-over-year decrease in the Company’s consolidated net benefit obligations was due to 
decreases in both pension liabilities and pension plan assets. Pension liabilities decreased on a global basis primarily due to increases in 
pension discount rates used to discount projected pension benefit payments. The Company’s pension discount rates are largely 
determined based on observable yields of investment grade corporate bonds or government issued debt-securities. Yields on these 
securities increased sharply in 2022 due, in part, to actions taken by many central banks to curb global inflation. The Company’s pension 
plan assets are reported at fair value. The fair value of the Company’s pension assets decreased on a global basis primarily due to 
unfavorable returns on the Company’s equity and fixed income investments.

(a)  $50.6 and $37.2 of settlement expense was recognized as special charges in 2022 and 2021, respectively.  

During 2022 and 2021, the Company incurred settlement expense in the U.S. of $51.6 million ($38.9 million after tax) and $35.3 million 
($26.8 million after tax), respectively, related to lump-sum payments to retirees in its U.S. pension plans. In addition to the U.S. qualified 
plan settlements in 2022 and 2021, the Company has historically recognized settlements and curtailment gains and losses associated 
with its U.S. nonqualified pension plans and International pension plans, the amounts of which have been historically not material. These 
charges have been included as a component of other (income) expense on the Consolidated Statements of Income.

The measurement of the Company’s pension and postretirement benefit obligations are dependent on a variety of assumptions 
determined by management and used by actuaries in their valuation method and calculations. The significant assumptions used in 
developing the required estimates of the projected benefit obligations are the discount rates, expected returns on assets, projected salary 
increases, and mortality tables. Assumptions for the Company were as follows: 

Plan Assumptions 

(percent) 
Weighted-average actuarial assumptions 
used to determine benefit obligations 
as of year end: 
Discount rate 
Projected salary increase 

Weighted-average actuarial assumptions 

used to determine net cost:

Discount rate assumptions for the U.S. plans are developed using a bond yield curve constructed from a population of high-quality, non-
callable, corporate bonds with maturities ranging from six months to thirty years. Discount rates are estimated for the U.S. plans based 
on the timing of the expected benefit payments. 

The Company measures service and interest costs by applying the specific spot rates along that yield curve to the plans’ liability cash 
flows. The Company believes this approach provides a more precise measurement of service and interest costs by aligning the timing of 
the plans’ liability cash flows to the corresponding spot rates on the yield curve.  

The expected long-term rate of return used for the U.S. plans is based on the respective pension plan’s asset mix. The Company 
considers expected long-term real returns on asset categories, expectations for inflation, and estimates of the impact of active 
management of the assets in determining the expected long-term rate of return to use. The Company also considers historical returns. 

The expected long-term rate of return used for the Company’s international plans is determined in each local jurisdiction and is based on 
the assets held in that jurisdiction, the expected rate of returns for the type of assets held and any guaranteed rate of return provided by 
the investment. The other assumptions used to measure the international pension obligations, including discount rate, vary by country 
based on specific local requirements and information.  

The Company uses mortality tables appropriate in the circumstances, which generally are the recent available mortality tables as of the 
respective U.S. and international measurement dates. The Company’s 2023 and 2022 year-end U.S. valuations reflect mortality tables 
that estimate the impacts of COVID in an endemic state. This represents a change from 2021 when the impact of COVID on future 
mortality could not be reasonably estimated. 

For postretirement benefit measurement purposes as of December 31, 2023, the annual rates of increase in the per capita cost of 
covered health care were assumed to be 7.46% for pre-65 costs. Post-65 costs are no longer used. The rates are assumed to decrease 
each year until they reach 4.5% in 2034 and remain at those levels thereafter. Health care costs for certain employees which are eligible 
for subsidy by the Company are limited by a cap on the subsidy. 

Plan Asset Management 

The Company’s U.S. investment strategy and policies are designed to maximize the possibility of having sufficient funds to meet the 
long-term liabilities of the qualified pension plan, while achieving a balance between the goals of asset growth of the qualified pension 
plan and keeping risk at a reasonable level. Investment income is not a primary goal of the policy.  

The asset allocation position reflects the Company’s ability and willingness to accept relatively more short-term variability in the 
performance of the qualified pension plan asset portfolio in exchange for the expectation of better long-term returns, lower pension costs 
and better funded status in the long run. The U.S. qualified pension plan’s asset are diversified across a number of asset classes and 
securities. Selected individual portfolios within the asset classes may be undiversified while maintaining the diversified nature of total plan 
assets. The Company has no significant concentration of risk in its U.S. qualified pension plan assets. 

Assets of funded international retirement plans are managed in each local jurisdiction and asset allocation strategy is set in accordance 
with local rules, regulations and practices; therefore, no overall target asset allocation is presented. Although foreign equity securities are 
all considered international for the Company, some equity securities are considered domestic for the local plan. The funds are invested in 
a variety of equities, bonds and real estate investments and, in some cases, the assets are managed by insurance companies which may 
offer a guaranteed rate of return. The Company has no significant concentration of risk in the assets of its international pension plans.

Depending on plan funding levels, the U.S. qualified pension plan provides certain terminating participants with an option to receive their 
pension benefits in the form of a lump sum payout. 

The Company is currently in compliance with all funding requirements of its U.S. pension and postretirement benefit plans. A $50.0 
million voluntary contribution was made to its non-contributory qualified U.S. pension plan in 2023. The Company is required to fund 
certain international pension benefit plans in accordance with local legal requirements. The Company estimates contributions to be made 
to its international plans will approximate $47 million in 2024.  

The Company seeks to maintain balance in its U.S. assets that meet the long-term funding requirements identified by the projections of 
the pension plans’ actuaries while simultaneously satisfying the fiduciary responsibilities prescribed in ERISA. The Company also takes 
into consideration the tax deductibility of contributions to the benefit plans. 

Savings Plan and ESOP  

The Company provides a 401(k) savings plan for the majority of its U.S. employees under the Company’s 401(k) savings plans, the 
Ecolab Savings Plan and ESOP (the “Ecolab Savings Plan”).  

Under the Ecolab Savings Plan, Employee before-tax contributions of up to 4% of eligible compensation are matched 100% by the 
Company and employee before-tax contributions over 4% and up to 8% of eligible compensation are matched 50% by the Company. 

The Company’s matching contributions are 100% vested immediately. The Company’s matching contribution expense was $88.2 million, 
$81.6 million and $78.2 million in 2023, 2022 and 2021, respectively.

17. REVENUES 

Revenue Recognition 

Product and Sold Equipment 

Product revenue is generated from sales of cleaning, sanitizing, water treatment, process treatment and colloidal silica products. In 
addition, the Company sells equipment which may be used in combination with its specialized products. Revenue recognized from 
product and sold equipment is recognized at the point in time when the obligations in the contract with the customer are satisfied, which 
generally occurs with the transfer of the product or delivery of the equipment. 

On June 3, 2020, the Company completed the separation of its Upstream Energy business (“ChampionX”). The Company entered into a 
Master Cross Supply and Product Transfer agreement with ChampionX to provide, receive or transfer certain products for a period up to 
36 months and for a smaller set of products with limited suppliers over the next few years. Sales of product to ChampionX under this 
agreement are recorded in product and equipment sales in the Corporate segment along with the related cost of sales, while purchases 
from ChampionX are recorded in inventory. Sales of product to ChampionX post-separation for 2023, 2022 and 2021 were $69.0 million, 
$123.8 million and $139.1 million, respectively. As of December 31, 2023 and 2022, the Company had an outstanding accounts 
receivable balance for sales of product to ChampionX of $3.8 and 12.9 million, respectively. 

Service and Lease Equipment 

Service and lease equipment revenue is generated from providing services or leasing equipment to customers. Service offerings include 
installing or repairing certain types of equipment, activities that supplement or replace headcount at the customer location, or fulfilling 
deliverables included in the contract. Global Industrial segment services are associated with water treatment and paper process 
applications. Global Institutional & Specialty services include cleaning and sanitizing programs and wash process solutions. Global 
Healthcare & Life Sciences segment services include pharmaceutical, personal care, infection and containment control solutions. 
Revenues included in Other primarily related to services designed to detect, eliminate and prevent pests. Service revenue is recognized 
over time utilizing an input method and aligns with when the services are provided. Typically, revenue is recognized over time using costs 
incurred to date because the effort provided by the field selling and service organization represents services provided, which corresponds 
with the transfer of control. Revenue recognized from leased equipment primarily relates to warewashing and water treatment equipment 
recognized on a straight-line basis over the length of the lease contract pursuant to Topic 842 Leases. Refer to Note 13 for additional 
information related to lease equipment. 

Practical Expedients and Exemptions 

The revenue standard can be applied to a portfolio of contracts with similar characteristics if it is reasonable that the effects of applying 
the standard at the portfolio level would not be significantly different than applying the standard at the individual contract level. The 
Company applies the portfolio approach primarily within each operating segment by geographical region. Application of the portfolio 
approach was focused on those characteristics that have the most significant accounting consequences in terms of their effect on the 
timing of revenue recognition or the amount of revenue recognized. The Company determined the key criteria to assess with respect to 
the portfolio approach, including the related deliverables, the characteristics of the customers and the timing and transfer of goods and 
services, which most closely aligned within the operating segments. In addition, the accountability for the business operations, as well as 
the operational decisions on how to go to market and the product offerings, are performed at the operating segment level.  

The following table shows principal activities, separated by reportable segments, from which the Company generates its revenue. The 
reportable segments have been revised to align with the Company’s reportable segments in the current year. Corporate segment 
includes sales to ChampionX under the Master Cross Supply and Product Transfer agreements entered into as part of the ChampionX 
Separation. For more information about the Company’s reportable segments, refer to Note 18.

Net sales by geographic region were determined based on origin of sale. There were no sales from a single foreign country or individual 
customer that were material to the Company’s consolidated net sales. Sales of warewashing products were approximately 12%, 12%, 
and 10% of consolidated net sales in 2023, 2022 and 2021, respectively.

Contract Liability 

Payments received from customers are based on invoices or billing schedules as established in contracts with customers. Accounts 
receivable are recorded when the right to consideration becomes unconditional. The contract liability relates to billings in advance of 
performance (primarily service obligations) under the contract. Contract liabilities are recognized as revenue when the performance 
obligation has been performed, which primarily occurs during the subsequent quarter.

18. OPERATING SEGMENTS AND GEOGRAPHIC INFORMATION 

The Company’s organizational structure consists of global business unit and global regional leadership teams. The Company’s ten 
operating segments follow its commercial and product-based activities and are based on engagement in business activities, availability of 
discrete financial information and review of operating results by the Chief Operating Decision Maker at the identified operating segment 
level.  

The Company’s operating segments that share similar economic characteristics and future prospects, nature of the products and 
production processes, end-use markets, channels of distribution and regulatory environment have been aggregated into three reportable 
segments: Global Industrial, Global Institutional & Specialty and Global Healthcare & Life Sciences. The Company’s operating segments 
that do not meet the quantitative criteria to be separately reported have been combined into Other. The Company provides similar 
information for Other as the Company considers the information regarding its underlying operating segments as useful in understanding 
its consolidated results. 

The Company’s operating segments are aggregated as follows: 

Global Industrial 

Includes the Water, Food & Beverage and Paper operating segments. It provides water treatment and process applications, and cleaning 
and sanitizing solutions primarily to large industrial customers within the manufacturing, food and beverage processing, transportation, 
chemical, primary metals and mining, power generation, pulp and paper, commercial laundry, global petroleum and petrochemical 
industries. The underlying operating segments exhibit similar manufacturing processes, distribution methods and economic 
characteristics. 

Global Institutional & Specialty 

Includes the Institutional and Specialty operating segments. It provides specialized cleaning and sanitizing products to the foodservice, 
hospitality, lodging, government and education and retail industries. The underlying operating segments exhibit similar manufacturing 
processes, distribution methods and economic characteristics. 

Global Healthcare & Life Sciences 

Includes the Healthcare and Life Sciences operating segments. It provides specialized cleaning and sanitizing products to the healthcare, 
personal care and pharmaceutical industries. The underlying operating segments exhibit similar manufacturing processes, distribution 
methods and economic characteristics. 

Other 

Includes the Pest Elimination operating segment which provides services to detect, eliminate and prevent pests, such as rodents and 
insects, the CTG operating segment which produces and sells colloidal silica, which is comprised of nano-sized particles of silica in water 
used primarily for binding and polishing applications and the Textile Care operating segment which provides products and services that 
manage the entire wash process through custom designed programs, premium products, dispensing equipment, water and energy 
management and reduction, and real time data management.  

Corporate 

Consistent with the Company’s internal management reporting, Corporate amounts in the table below include sales to ChampionX under 
the Master Cross Supply and Product Transfer agreements entered into as part of the ChampionX Separation, as discussed in Note 4. 
Corporate also includes intangible asset amortization specifically from the Nalco and Purolite acquisitions and special (gains) and 
charges, as discussed in Note 3, that are not allocated to the Company’s reportable segments.

Comparability of Reportable Segments 

Effective January 1, 2023, the Company’s former Downstream operating segment is now part of the Water operating segment. This 
change did not have any impact on the Global Industrial reportable segment. 

The Company evaluates the performance of its non-U.S. dollar functional currency international operations based on fixed currency 
exchange rates, which eliminate the impact of exchange rate fluctuations on its international operations. Fixed currency amounts are 
updated annually at the beginning of each year based on translation into U.S. dollars at foreign currency exchange rates established by 
management, with all periods presented using such rates. The “Fixed Currency Rate Change” column shown in the following table 
reflects international operations at fixed currency exchange rates established by management at the beginning of 2023, rather than the 
2022 established rates. The difference between the fixed currency exchange rates and the actual currency exchange rates is reported 
within the “Effect of foreign currency translation” row in the following table. The “Other” column shown in the following table reflects 
immaterial changes between reportable segments, including the movement of certain customers and cost allocations. 

The impact of the preceding changes on previously reported full year 2022 and 2021 reportable segment net sales and operating income 
is summarized as follows:

The profitability of the Company’s operating segments is evaluated by management based on operating income.  

Consistent with the Company’s internal management reporting, Corporate amounts in the table above include sales to ChampionX in 
accordance with the long-term supply agreement entered into with the Transaction, as discussed in Note 17. Corporate also includes 
intangible asset amortization specifically from the Nalco and Purolite acquisitions and special (gains) and charges, as discussed in Note 
3, that are not allocated to the Company’s reportable segments. 

The Company has an integrated supply chain function that serves all of its reportable segments. As such, asset and capital expenditure 
information by reportable segment has not been provided and is not available, since the Company does not produce or utilize such 
information internally. In addition, although depreciation and amortization expense is a component of each reportable segment’s 
operating results, it is not discretely identifiable.

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures   

As of December 31, 2023, we carried out an evaluation, under the supervision and with the participation of our management, including 
our Chairman and Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our 
disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 as amended). 
Based upon that evaluation, our Chairman and Chief Executive Officer and our Chief Financial Officer concluded that, as of December

Changes in Internal Control Over Financial Reporting. 

During the period October 1, 2023 through December 31, 2023 there were no changes in our internal control over financial reporting that 
have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 

We are continuing our implementation of our enterprise resource planning (“ERP”) system upgrades, which are expected to occur in 
phases over the next several years. These upgrades, which include supply chain and certain finance functions, are expected to improve 
the efficiency of certain financial and related transactional processes. These upgrades of the ERP systems will affect the processes that 
constitute our internal control over financial reporting and will require testing for effectiveness.
