PART 1
ITEM 1 – BUSINESS
As used in this annual report on Form 10-K, references to the “Company,” “A. O. Smith,” “AOS,” “we,” “us,” and “our” refer to A. O. Smith and its consolidated subsidiaries. The following discussion should be read in conjunction with our consolidated financial statements and notes thereto under “Item 8 Financial Statements and Supplementary Data” in this annual report on Form 10-K. Our company is comprised of two reporting segments: North America and Rest of World. Both segments manufacture and market comprehensive lines of residential and commercial gas and electric water heaters, boilers, heat pump, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world. Our Rest of World segment is primarily comprised of China, Europe and India.
NORTH AMERICA
Sales in our North America segment accounts for 74% of our total sales in 2022. This segment serves residential and commercial end markets with a broad range of products including:
Water heaters. Our residential and commercial water heaters, primarily come in sizes ranging from 40 to 80 gallon models, however, we also offer sizes as low as 2.5 gallon (point-of-use) and as high as 2,500 gallon products with varying efficiency ranges. We offer electric, natural gas and liquid propane tank-type models as well as tankless (gas and electric), heat pump and solar tank units. Typical applications for our water heaters include residences, restaurants, hotels, office buildings, laundries, car washes, schools and small businesses. In 2022, we continued our integration activities of Giant Factories, Inc., (Giant) a Canada-based manufacturer of residential and commercial water heaters, which we acquired in late 2021.
Boilers. Our residential and commercial boilers range in size from 45,000 British Thermal Units (BTUs) to 6.0 million BTUs. Boilers are closed loop water heating systems used primarily for space heating or hydronic heating. Our boilers are primarily used in applications in commercial settings for hospitals, schools, hotels and other large commercial buildings while residential boilers are used in homes, apartments and condominiums.
Water treatment products. With the acquisition of Aquasana, Inc. (Aquasana) in 2016 we entered the water treatment market. We expanded our product offerings with the acquisitions of Hague Quality Water International (Hague) in 2017, Water-Right, Inc. (Water-Right) in 2019, Master Water Conditioning Corporation (Master Water) in 2021 and Atlantic Filter Corporation (Atlantic Filter) in 2022. Our water treatment products range from point-of-entry water softeners, solutions for problem well water, and whole-home water filtration products to on-the-go filtration bottles and point-of-use carbon and reverse osmosis products. We also offer a comprehensive line of commercial water treatment and filtration products. Typical applications for our water treatment products include residences, restaurants, hotels and offices.
Other. In our North America segment, we also manufacture expansion tanks, commercial solar water heating systems, swimming pool and spa heaters, related products and parts.
A significant portion of our North America sales is derived from the replacement of existing products.
We believe we are the largest manufacturer and marketer of water heaters in North America with a leading share in both the residential and commercial portions of the market. In the commercial portions of the market for both water heating and space heating, we believe our comprehensive product lines and our high-efficiency products give us a competitive advantage. Our wholesale distribution channel, where we sell our products primarily under the A. O. Smith and State brands, includes more than 1,000 independent wholesale plumbing distributors serving residential and commercial end markets. We also sell our residential water heaters through the retail and maintenance, repair and operations (MRO) channels. In the retail channel, our customers include four of the six largest national hardware and home center chains, including a long-standing exclusive relationship with Lowe’s where we sell A. O. Smith branded products.
Our Lochinvar brand is one of the leading residential and commercial boiler brands in the U.S. Approximately 40 percent of Lochinvar branded sales consist of residential and commercial water heaters while the remaining 60 percent of Lochinvar branded sales consist primarily of boilers and related parts. Our commercial boiler distribution channel is primarily comprised of manufacturer representative firms with the remainder of our Lochinvar branded products being distributed through wholesale channels.
We sell our A. O. Smith branded water treatment products through Lowe's and Amazon. Our Aquasana branded products are primarily sold directly to consumers through e-commerce channels. Our water softener products and problem well water solutions, which include Hague, Water-Right, Master Water, and Atlantic Filter, are sold through water quality dealers. Our water softener products are also sold through home center retail chains.

Our energy-efficient product offerings continue to be a sales driver for our business. Our condensing commercial water heaters and boilers continue to be an option for commercial customers looking for high-efficiency water and space heating with a short payback period through energy savings. We offer residential heat pump, condensing tank-type and tankless water heaters in North America, as well as other higher efficiency water heating solutions to round out our energy-efficient product offerings. In addition, during 2021 we launched a commercial heat pump water heater to align with greenhouse gas emission reduction trends across the U.S.
We sell our products in highly competitive markets. We compete in each of our targeted market segments based on product design, reliability, quality of products and services, advanced technologies, energy efficiency, maintenance costs and price. Our principal water heating and boiler competitors in North America include Rheem, Bradford White, Rinnai, Aerco and Navien. Numerous other manufacturing companies also compete. Our principal water treatment competitors in the U.S. are Culligan, Kinetico, Pentair, Franklin Electric and Ecowater as well as numerous regional assemblers.
REST OF WORLD
Sales in our Rest of World segment accounts for 26% of our total sales in 2022, a majority of which is in China. We have operated in China for nearly 30 years. In that time, we have established A. O. Smith brand recognition in the residential and commercial markets. We manufacture and market residential water heater and water treatment products, primarily incorporating reverse osmosis technology, and commercial water treatment products. The Chinese water heater market is predominantly comprised of electric wall-hung, gas tankless, combi-boiler, heat pump and solar water heaters. We believe we are one of the market leaders of water heaters and reverse osmosis water treatment products to the residential market in China in dollar terms. We also design and market range hoods and cooktops in China.
We sell our products in approximately 12,000 points of sale in China, of which approximately 5,400 are retail outlets in tier one through tier three cities and approximately 2,000 exclusively sell our products. We also sell our products through e-commerce channels. Our primary competitors in China in the water heater market segment are Haier, Midea, and Rinnai. Our principal competitors in the water treatment market are Angel, Midea, Truliva, and Xiaomi.
In 2008, we established a sales office in India and began importing products specifically designed for India. We began manufacturing water heaters in India in 2010 and water treatment products in 2015. We continue to expand our product offerings and sales in this country, primarily through wholesale, e-commerce and retail channels. Our primary competitors in India are Racold, Bajaj and Havells in the water heater market and Eureka Forbes, Kent and Hindustan Unilever in the water treatment market.
We also sell water heaters in the European and Middle and Far Eastern markets and water treatment products in Hong Kong, and Vietnam, all of which combined comprised less than 13 percent of total Rest of World sales in 2022.
RAW MATERIALS
We use a wide range of raw materials in our manufacturing operations. These raw materials are generally available in adequate quantities, however, the COVID-19 pandemic and disruptions in the commercial transportation network have stressed the availability of certain raw materials. While supply chain and logistics challenges lingered in 2022, we saw improvement, particularly in the second half of the year. Our primary raw material input is steel which has experienced volatility in costs over the last several years. A portion of our customers have contractual pricing tied to a steel price index.
RESEARCH AND DEVELOPMENT
To improve our competitiveness by generating new products and processes, we conduct research and development at our Corporate Technology Center in Milwaukee, Wisconsin, our Global Engineering Center in Nanjing, China, and our operating locations. Our total expenditures for research and development in 2022, 2021 and 2020 were $89.0 million, $94.2 million and $80.7 million, respectively.
PATENTS AND TRADEMARKS
We invest, own and use in our businesses various trademarks, trade names, patents, trade secrets and licenses. We monitor our intellectual property for infringement and in 2022 received a judgment of $11.5 million against a competitor related to one of our patents. Although we believe our trademarks, trade names, patents, trade secrets, and licenses to constitute a valuable asset in the aggregate, we do not regard our business as being materially dependent on any single trademark, trade name, patent, trade secret, license or any group of related such rights. Our trade name is important with respect to our products, particularly in China, India, and North America.

HUMAN CAPITAL
We employed approximately 12,000 employees as of December 31, 2022 with approximately 6,200 in North America and 5,800 in Rest of World. A small portion of our workforce in the U.S. is represented by a labor union, while outside the U.S., we have employees in certain countries that are represented by employee representative organizations, such as an employee association, union, or works council.
Our Guiding Principles and Values. The foundation of how we conduct business and interact with our employees is outlined in A. O. Smith Corporation’s Guiding Principles and our Statement of Values. These principles and values help to shape how we hire, train and treat our employees, emphasizing teamwork and promoting diversity in seeking our objectives. We believe that our Guiding Principles and Values shape the critical elements of our effort to attract, retain and develop talent.
Culture and Employee Engagement. We conduct a Global Employee Engagement Survey on a biannual basis. This third party managed survey measures employees’ level of engagement against external norms and provides us with actionable feedback that drives improvement priorities. Survey participation in 2022 was 97 percent, which we believe reflects our employees’ desire to share their perspectives and a commitment to continuous improvement. Survey results help shape action plans to further improve our culture and we will conduct the survey again in 2024.
Diversity and Inclusion. As reflected in our Guiding Principles, we strive to create a workplace where people from diverse backgrounds can thrive and achieve their fullest potential. A. O. Smith’s commitment to this objective starts at the top with its Board of Directors, which is 50% diverse. A. O. Smith monitors the gender and racial composition of its workforce in the U.S. at various levels within the organization, and also tracks pay equity on an ongoing basis.
Compensation and Benefits. We provide what we believe is a robust total compensation program designed to be market-competitive and internally equitable to attract, retain, motivate and reward a high-performance workforce. Regular internal and external analysis is performed to ensure this market alignment. In addition to salaries, these programs, which vary by country, can include annual performance-based bonuses, stock-based compensation awards, retirement plans with employee matching opportunities, health benefits, health savings and flexible spending accounts, paid time off, family leave, and tuition assistance, among others.
Training and Development. We provide all employees with a wide range of professional development experiences, both formal and informal, to help them achieve their full potential. All of of our salaried employees are given formal development plans. Some of the formal development programs that employees have access to include early-career leadership development programs, front-line leadership development programs, continuous improvement skill-building programs, core process technology councils and tuition reimbursement for degree programs or trade schools. In 2022, we partnered with a third party provider to deliver diversity and inclusive leadership training to enhance the capability of our workforce with a program that aligns with our Guiding Principles, Values, and overall leadership approach. In 2022, we provided this training to our senior leadership team globally and senior management in the U.S., and we intend to expand that training program in 2023. Globally, all office and professional employees also have formal performance reviews and development plans with a focus on learning by doing. We expect our managers to work closely with their employees to ensure performance feedback and to conduct development discussions on a regular basis.
Safety. The safety of our people is always at the forefront of what we do. We provide safety training in our production facilities, designed to empower our employees with the knowledge and tools they need to make safe choices and mitigate risks. In addition to traditional training, we use standardized signage and visual management throughout our facilities. Since 1954, we have awarded annually the Lloyd B. Smith President's Safety Award, which acknowledges an A. O. Smith facility that demonstrates the most improvement over one year in the area of workplace safety.
BACKLOG
Due to the short-cycle nature of our businesses, our operations do not normally sustain significant backlogs.

GOVERNMENT REGULATIONS AND ENVIRONMENTAL MATTERS
Our operations, including the manufacture, packaging, labeling, storage, distribution, advertising and sale of our products, are subject to various federal, state, local and foreign laws and regulations. In the U.S., many of our products are regulated by the Department of Energy, the Consumer Product Safety Commission, and the Federal Trade Commission. State and local governments, through laws, regulations, and building codes, also regulate our water heating and water treatment products. Whether at the federal, state, or local level, these laws are intended to improve energy efficiency and product safety, and protect public health and the environment. In recent years, a limited number of states and local authorities have proposed or implemented bans on gas-fired products in new construction in an effort to address greenhouse gas emissions. Similar laws and regulations have been adopted by government authorities in other countries in which we manufacture, distribute, and sell our products. We offer a complete line of water and hydronic heating products, including electric-powered water heaters and boilers, and we believe that any reduction in fossil fuel-powered products would be counterbalanced by the demand for our non-fossil fuel powered products. We are confident that our continued emphasis on product design and innovation will keep us well positioned to deliver products demanded by customers, regardless of fuel source.
In addition, our operations are subject to federal, state and local environmental laws. We are subject to regulations of the U.S. Environmental Protection Agency and the Occupational Health and Safety Administration and their counterpart state agencies. Compliance with government regulations and environmental laws has not had and is not expected to have a material effect upon the capital expenditures, earnings, or competitive position of our company. See Item 3.

ITEM 1A – RISK FACTORS
In the ordinary course of our business, we face various strategic, operating, compliance and financial risks. These risks could have an impact on our business, financial condition, operating results and cash flows. The risks set forth below are not an exhaustive list of potential risks but reflect those that we believe to be material. You should carefully consider the risk factors set forth below and all other information contained in this Annual Report on Form 10-K, including the documents incorporated by reference, before making an investment decision regarding our common stock. If any of the events contemplated by the following risks were to actually occur, then our business, financial condition, or results of operations could be materially adversely affected. As a result, the trading price of our common stock could decline, and you may lose all or part of your investment.
Economic and Industry Risks
The effects of global and regional economic conditions could have a material adverse effect on our business
A decline in economic activity, such as a recession or economic downturn, in the U.S. and other regions in the world in which we do business, could adversely affect consumer confidence and spending patterns which could result in decreased demand for the products we sell, a delay in purchases, increased price competition, slower adoption of energy-efficient water heaters and boilers, or high-quality water treatment products, which could negatively impact our profitability and cash flows. Such deterioration in economic conditions could arise from many factors or fears including public health crises, political instability or risk of government default. In addition, an increase in price levels generally or in particular industries (such as the inflation in steel prices in 2021 and the recent inflation in other material and logistics costs), could result in a consumer shift away from the products we offer, which could adversely affect our revenues and, at the same time, increase our costs. A deterioration in economic conditions also could negatively impact our vendors and customers, which could result in an increase in bad debt expense, customer and vendor bankruptcies, interruption or delay in supply of materials, or increased material prices, which could negatively impact our ability to distribute, market and sell our products and our financial condition, results of operations and cash flows.
The occurrence or threat of extraordinary events, including natural disasters, political disruptions, terrorist attacks, public health issues, and acts of war, could significantly disrupt production, or impact consumer spending
As a global company with a large international footprint, we are subject to increased risk of damage or disruption to us and our employees, facilities, suppliers, distributors, or customers. Extraordinary events, including natural disasters, resulting from but not limited to climate change, political disruptions, terrorist attacks, public health issues, such as the COVID-19 pandemic, and acts of war may disrupt our business and operations and impact our supply chain and access to necessary raw materials or could adversely affect the economy generally, resulting in a loss of sales and customers. Any of these disruptions or other extraordinary events outside of our control that impact our operations or the operations of our suppliers and key distributors could affect our business negatively, harming operating results.
The COVID-19 pandemic continues to cause disruption to the global economy. We continue to monitor the pandemic, and while periodic local increases and decreases in COVID-19 cases are likely, generally the restrictions due to and in response to the pandemic continue to relax in most locations. However, the COVID-19 pandemic and efforts to manage it, including those by governmental authorities, could have a material adverse effect on our financial condition, results of operations and cash flows.
Natural disasters and extreme weather conditions may disrupt the productivity of our facilities. For example, two of our manufacturing plants are located within a floodplain that has experienced past flooding events. We also have other manufacturing facilities located in hurricane and earthquake zones. We maintain insurance coverage and have taken steps to mitigate these physical risks related to natural disasters and extreme weather conditions. Pricing for our insurance program has remained at the prevailing market rate with no significant change in the current year’s premium rates from the prior year. Also, to mitigate the risk of flooding, we recently completed an approximately 7,000-foot-long berm, flood gates, and pumping stations around our Ashland City, Tennessee facility, our largest manufacturing facility. Despite our mitigation efforts, there is still the potential for natural disasters and extreme weather conditions to disrupt the productivity of our facilities.
Apart from the potential impact on our operations, these types of events also could negatively impact consumer spending in the impacted regions or depending on the severity, globally, which could materially and adversely affect our financial condition, results of operations and cash flows.

Our business could be adversely impacted by changes in consumer purchasing behavior, consumer preferences, technological changes, and market trends
Consumer preferences for products and the methods in which they purchase products are constantly changing based on, among other factors, cost, performance, convenience, environmental and social concerns and perceptions. Consumer purchasing behavior may shift the product mix in the markets in which we participate or result in a shift to other distribution channels, for example e-commerce. Consumer preferences and broader trends, such as decarbonization and electrification efforts in response to climate change, may result in increased demand for higher efficiency products and/or more electric powered products. In addition, technologies are ever changing. Our ability to respond to these trends, timely transition our product portfolio, develop new and innovative products, and acquire and protect the necessary intellectual property rights is essential to our continued success, but cannot reasonably be assured. It is possible that we will not be able to develop new technologies, products or distribution channels, or do so on a timely basis, to align with consumer purchasing behavior and consumer preferences, which could materially and adversely affect our financial condition, results of operations and cash flows.
Our operations could be adversely impacted by material and component price volatility, as well as supplier concentration
The market prices for certain materials and components we purchase, primarily steel, have been volatile. We have also experienced inflation related increases in our transportation costs. Significant increases in the cost of any of the key materials and components we purchase would increase our cost of doing business and ultimately could lead to lower operating earnings if we are not able to recover these cost increases through price increases to our customers. Historically, there has been a lag in our ability to recover increased material costs from customers, and that lag, could negatively impact our profitability. In some cases, we are dependent on a limited number of suppliers for some of the raw materials and components we require in the manufacturing of our products. A significant disruption or termination of the supply from one of these suppliers could delay sales or increase costs which could result in a material adverse effect on our financial condition, results of operations and cash flows.
Because we participate in markets that are highly competitive, our revenues and earnings could decline as we respond to competition
We sell all of our products in highly competitive and evolving markets. We compete in each of our targeted markets based on product design, reliability, quality of products and services, advanced technologies, product performance, maintenance costs and price. Some of our competitors may have greater financial, marketing, manufacturing, research and development and distribution resources than we have; others may invest little in technology or product development but compete on price and the rapid replication of features, benefits, and technologies, and some are increasingly expanding beyond their existing manufacturing or geographic footprints. In North America, the gas tankless portion of the water heating market has for many years increased as a percentage of the overall market. While we have many gas tankless products, our market share for gas tankless products is lower than our market share for the remainder of the water heating market. Further expansion of the gas tankless portion of the North America market, which we believe was approximately 11 percent of the residential market segment in 2022, could have an impact on our operating results. We cannot assure that our products will continue to compete successfully with those of our competitors. There could be new market participants that change the dynamics of those markets and it is possible that we will not be able to retain our customer base or improve or maintain our profit margins on sales to our customers, all of which could materially and adversely affect our financial condition, results of operations and cash flows.
Because approximately 22 percent of our sales in 2022 were attributable to China, adverse economic conditions or changes in consumer behavior in China could impact our business
Our sales in China decreased five percent in local currency in 2022 compared to 2021. Our 2022 sales in China were impacted by lower consumer demand driven by COVID-19 related disruptions. Certain COVID-19 restrictions were lifted at the end of 2022 but could return. We derive a substantial portion of our sales in China from premium-tier products. Changes in consumer preferences and purchasing behaviors including preferences for e-commerce, weakening consumer confidence and sentiment as well as economic uncertainty, socio-political risks, increased competition from Chinese-based companies, and potential future COVID-19 related impacts, may prompt Chinese consumers to postpone purchases, choose lower-priced products or different alternatives, or lengthen the cycle of replacement purchases. Further deterioration in the Chinese economy may adversely affect our financial condition, results of operations and cash flows.

Table of Contents
Business, Operational, and Strategic Risks
We sell our products and operate outside the U.S., and to a lesser extent, rely on imports and exports, which may present additional risks to our business
Approximately 34 percent of our sales in 2022 were attributable to products sold outside of the U.S., primarily in China and Canada, and to a lesser extent in Europe and India. We also have operations and business relationships outside the U.S. that comprise a portion of our manufacturing, supply, and distribution. Approximately 5,200 of our 12,000 employees as of December 31, 2022 were located in China. At December 31, 2022, approximately $472 million of cash and marketable securities were held by our foreign subsidiaries, substantially all of which were located in China. International operations generally are subject to various risks, including: political, religious, and economic instability; local labor market conditions; new or increased tariffs or other trade restrictions, or changes to trade agreements; the impact of foreign government regulations, actions or policies; the effects of income taxes; governmental expropriation; the changes or imposition of statutory restrictions which prohibit repatriation of cash; the imposition or increases in withholding and other taxes on remittances and other payments by foreign subsidiaries; labor relations problems; the imposition of environmental or employment laws, or other restrictions or actions by foreign governments; and differences in business practices. Unfavorable changes in the political, regulatory, or trade climate, diplomatic relations, or government policies, particularly in relation to countries where we have a presence, including Canada, China, India and Mexico, could have a material adverse effect on our financial condition, results of operations and cash flows or our ability to repatriate funds to the U.S.
A material loss, cancellation, reduction, or delay in purchases by one or more of our largest customers could harm our business
Sales to our five largest customers represented approximately 39 percent of our sales in 2022. We expect that our customer concentration will continue for the foreseeable future. Our concentration of sales to a relatively small number of customers makes our relationships with each of these customers important to our business. We cannot assure that we will be able to retain our largest customers. Some of our customers may shift their purchases to our competitors in the future. Our customers may experience financial instability, affecting their ability to make or pay for future purchases. Further, a customer may be acquired by a customer of a competitor which could result in our loss of that customer. The loss of one or more of our largest customers, any material reduction or delay in sales to these customers, or our inability to successfully develop relationships with additional customers could have a material adverse effect on our financial position, results of operations and cash flows.
A portion of our business could be adversely affected by a further decline in North American new residential or commercial construction or a decline in replacement-related volume of water heaters and boilers, including a decline in demand for commercial spaces
Residential new construction activity in North America and industry-wide replacement-related volume of water heaters had growth in 2020 and 2021, and then declined in 2022. New residential housing starts in the U.S. are projected to decrease further in 2023 compared to 2022. Commercial construction activity in North America grew in 2022 and 2021 after declining in 2020. We believe that the significant majority of the markets we serve are for the replacement of existing products, and residential water heater replacement volume was strong in 2022 and 2021. As a result of the COVID-19 pandemic, businesses and commercial spaces have experienced and may experience in the future, fluctuation in demand and in occupancy that may reduce demand for our products, and commercial sectors, such as the restaurant and hospitality industries in which we have customers, may experience long-term shifts in consumer behavior which could negatively impact demand or capacity and may not return to pre-pandemic levels. In addition, the acceptance of remote work arrangements could negatively impact demand for commercial construction. Changes in the replacement volume and in the construction market in North America could negatively affect us.
An inability to adequately maintain our information systems and their security, as well as to protect data and other confidential information, could adversely affect our business and reputation
In the ordinary course of business, we utilize information systems for day-to-day operations, to collect and store sensitive data and information, including our proprietary and regulated business information and personally identifiable information of our customers, suppliers and business partners, as well as personally identifiable information about our employees. Our information systems are susceptible to outages due to system failures, cybersecurity threats, failures on the part of third-party information system providers, natural disasters, power loss, telecommunications failures, viruses, fraud, theft, malicious actors or breaches of security. Like many companies, we, and some third parties upon which we rely, have experienced cybersecurity incidents and attacks on information technology networks and systems, products and services in the past but, to date, none have resulted in a material breach or had a material adverse impact on our financial condition, results of operations, or cash flows. We may experience them in the future, potentially with increasing frequency from increasingly

sophisticated cyber threats. In addition, as a result of the COVID-19 pandemic, remote work and remote access to our systems have increased, which may heighten these risks. A successful attack in the future could result in operations failure or breach of security that could lead to disruptions of our business activities, the loss or disclosure of both our and our customers’ financial, product and other confidential information and could result in regulatory actions, litigation and have a material adverse effect on our financial condition, results of operations and cash flows and our reputation. We have a response plan in place in the event of a data breach and we have an active program to maintain and improve data security and address these risks and uncertainties by implementing and improving internal controls, security technologies, insurance programs, network and data center resiliency and recovery processes.
Our international operations are subject to risks related to foreign currencies
We have a significant presence outside of the U.S., primarily in China and Canada and to a lesser extent Europe, Mexico, and India, and therefore, hold assets, including $377 million of cash and marketable securities denominated in Chinese renminbi, incur liabilities, earn revenues and pay expenses in a variety of currencies other than the U.S. dollar. The financial statements of our foreign subsidiaries are translated into U.S. dollars in our consolidated financial statements. Furthermore, typically our products are priced in foreign countries in local currencies. As a result, we are subject to risks associated with operating in foreign countries, including fluctuations in currency exchange rates and interest rates, hyperinflation in some foreign countries such as Turkey, where we currently have minor operations, or global exchange rate instability or volatility that strengthens the U.S. dollar against foreign currencies. An increase in the value of the U.S. dollar relative to the local currencies of our foreign markets, as experienced globally in the second half of 2022, has negatively affected our sales, profitability, and cash and cash equivalents balances and could have such effects in the future. In 2022, the change in foreign currencies negatively impacted our sales and cash and cash equivalents by approximately $61 million and $21 million, respectively. In addition to currency translation risks, we incur a currency transaction risk whenever one of our subsidiaries enters into a purchase or sale transaction using a currency different from the operating subsidiaries’ functional currency. The majority of our foreign currency transaction risk results from sales of our products in Canada, a portion of which we manufacture in the U.S, and to a lesser extent from component purchases in Europe and India and payroll in Mexico. These risks may adversely impact our reported sales and profits in the future or negatively impact revenues and earnings translated from foreign currencies into U.S. dollars.
Our business may be adversely impacted by product defects
Product defects can occur through our own product development, design and manufacturing processes or through our reliance on third parties for component design and manufacturing activities. We may incur various expenses related to product defects, including product warranty costs, product liability and recall or retrofit costs. While we maintain a reserve for product warranty costs based on certain estimates and our knowledge of current events and actions, our actual warranty costs may exceed our reserve, resulting in current period expenses and a need to increase our reserves for warranty charges. In addition, product defects and recalls may diminish the reputation of our brand. Further, our inability to cure a product defect could result in the failure of a product line or the temporary or permanent withdrawal from a product or market. Any of these events may have a material adverse impact on our financial condition, results of operations and cash flows.
Potential acquisitions could use a significant portion of our capital and we may not successfully integrate future acquisitions or operate them profitably or achieve strategic objectives
We acquired Giant, a Canada-based manufacturer of residential and commercial water heaters, on October 19, 2021, for $199 million subject to customary adjustments using a combination of cash and debt. We will continue to evaluate potential acquisitions, and we could use a significant portion of our available capital to fund future acquisitions. We may not be able to successfully integrate Giant or any future acquired businesses or operate them profitably or accomplish our strategic objectives for those acquisitions. If we complete any future acquisitions in new geographies, our unfamiliarity with relevant regulations and market conditions may impact our ability to operate them profitably or achieve our strategic objectives for those acquisitions. Our level of indebtedness may increase in the future if we finance acquisitions with debt, which would cause us to incur additional interest expense and could increase our vulnerability to general adverse economic and industry conditions and limit our ability to service our debt or obtain additional financing. The impact of future acquisitions may have a material adverse effect on our financial condition, results of operations and cash flows.

Legal, Regulatory, and Governance Risks
Changes in regulations or standards, such as those associated with climate change, could adversely affect our business
Our products are subject to a wide variety of statutory, regulatory and industry standards and requirements related to, among other items, energy and water efficiency, environmental emissions, labeling and safety. We believe our products are currently efficient, safe and environment-friendly. However, a limited number of federal, foreign, state and local governments are adopting laws, regulations and codes in response to climate change that require a transition to non-fossil fuel based sources of energy production as well as significantly reducing or eliminating the on-site combustion of fossil fuels in the building sector, such as limiting or prohibiting the delivery of natural gas in new construction. A significant change to regulatory requirements that promote a transition to alternative energy sources as a replacement for gas, or a significant shift in industry standards, could substantially increase manufacturing costs, capital expenditures, transportation costs and raw material costs, impact the size and timing of demand for our products, affect the types of products we are able to offer or put us at a competitive disadvantage, any of which could harm our business and have a material adverse effect on our financial condition, results of operations and cash flow.
We are subject to U.S. and global laws and regulations covering our domestic and international operations that could adversely affect our business and results of operations
Due to our global operations, we are subject to many laws governing international relations, including those that prohibit improper payments to government officials and restrict where we can do business, what information or products we can supply to certain countries and what information we can provide to a non-U.S. government, including but not limited to the Foreign Corrupt Practices Act and the U.S. Export Administration Act. Violations of these laws may result in criminal penalties or sanctions that could have a material adverse effect on our financial condition, results of operations and cash flows.
Our Environmental, Social, and Governance (ESG) commitments could result in additional costs, and our inability to achieve them could have an adverse impact on our reputation and performance
We periodically communicate our strategies, commitments and targets related to ESG matters, including carbon emissions, diversity and inclusion, and human rights through the issuance of our ESG report. Although we intend to meet these strategies, commitments and targets and are committed to advancing sustainable innovations in our industry, we may be unable to achieve them due to impacts on resources, operational costs, and technological advancements. Failure to meet these sustainability requirements or targets could adversely impact our reputation as well as the demand for our products and adversely affect our business, financial condition and results of operations. In addition, standards and processes for measuring and reporting carbon emissions and other sustainability metrics may change over time, result in inconsistent data, or result in significant revisions to our strategies, commitments and targets, or our ability to achieve them. Any scrutiny of our carbon emissions or other sustainability disclosures or our failure to achieve related strategies, commitments and targets could negatively impact our reputation or performance.
Our results of operations may be negatively impacted by product liability lawsuits and claims
Our products expose us to potential product liability risks that are inherent in the design, manufacture, sale and use of our products. While we currently maintain what we believe to be suitable product liability insurance, we cannot be certain that we will be able to maintain this insurance on acceptable terms, that this insurance will provide adequate protection against potential liabilities or that our insurance providers will be able to ultimately pay all insured losses. In addition, we self-insure a portion of product liability claims. A series of successful claims against us could materially and adversely affect our reputation and our financial condition, results of operations and cash flows.
We have significant goodwill and indefinite-lived intangible assets and an impairment of our goodwill or indefinite-lived intangible assets could cause a decline in our net worth
Our total assets include significant goodwill and indefinite-lived intangible assets. Our goodwill results from our acquisitions, representing the excess of the purchase prices we paid over the fair value of the net tangible and intangible assets we acquired. We assess whether there have been impairments in the value of our goodwill or indefinite-lived intangible assets during the fourth quarter of each calendar year or sooner if triggering events warrant. If future operating performance at our businesses does not meet expectations, we may be required to reflect non-cash charges to operating results for goodwill or indefinite-lived intangible asset impairments. The recognition of an impairment of a significant portion of goodwill or indefinite-lived intangible assets would negatively affect our results of operations and total capitalization, the effect of which could be material. A significant reduction in our stockholders’ equity due to an impairment of goodwill or indefinite-lived intangible assets may affect our ability to maintain the debt-to-capital ratio required under our existing debt arrangements.

Table of Contents
We have identified the valuation of goodwill and indefinite-lived intangible assets as a critical accounting policy. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies—Goodwill and Indefinite-lived Intangible Assets” included in Item 7 of this Annual Report on Form 10-K.
Certain members of the founding family of our company and trusts for their benefit have the ability to influence all matters requiring stockholder approval
We have two classes of common equity: our Common Stock and our Class A Common Stock. The holders of Common Stock currently are entitled, as a class, to elect only one-third of our Board of Directors. The holders of Class A Common Stock are entitled, as a class, to elect the remaining directors. Certain members of the founding family of our company and trusts for their benefit (Smith Family) have entered into a voting trust agreement with respect to shares of our Class A Common Stock and shares of our Common Stock they own. As of December 31, 2022, through the voting trust, these members of the Smith Family own approximately 65.6 percent of the total voting power of our outstanding shares of Class A Common Stock and Common Stock, taken together as a single class, and approximately 96.8 percent of the voting power of the outstanding shares of our Class A Common Stock, as a separate class. Due to the differences in the voting rights between shares of our Common Stock (one-tenth of one vote per share) and shares of our Class A Common Stock (one vote per share), the Smith Family voting trust is in a position to control to a large extent the outcome of matters requiring a stockholder vote, including the adoption of amendments to our certificate of incorporation or bylaws or approval of transactions involving a change of control. This ownership position may increase if other members of the Smith Family enter into the voting trust agreement, and the voting power relating to this ownership position may increase if shares of our Class A Common Stock held by stockholders who are not parties to the voting trust agreement are converted into shares of our Common Stock. The voting trust agreement provides that, in the event one of the parties to the voting trust agreement wants to withdraw from the trust or transfer any of its shares of our Class A Common Stock, such shares of our Class A Common Stock are automatically exchanged for shares of our Common Stock held by the trust to the extent available in the trust. In addition, the trust will have the right to purchase the shares of our Class A Common Stock and our Common Stock proposed to be withdrawn or transferred from the trust. As a result, the Smith Family members that are parties to the voting trust agreement have the ability to maintain their collective voting rights in our company even if certain members of the Smith Family decide to transfer their shares.

PART II
ITEM 5 – MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES
(a)Market Information. Our Common Stock is listed on the New York Stock Exchange under the symbol AOS. Our Class A Common Stock is not listed. EQ Shareowner Services, P.O. Box 64874, St. Paul, Minnesota, 55164-0874 serves as the registrar, stock transfer agent and the dividend reinvestment agent for our Common Stock and Class A Common Stock.
(b)Holders. As of January 31, 2023, the approximate number of stockholders of record of Common Stock and Class A Common Stock were 526 and 144, respectively. The actual number of stockholders is greater than this number of holders of record, and includes stockholders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. This number of stockholders of record also does not include stockholders whose shares may be held in trust by other entities.
(c)Dividends. Dividends declared on the common stock are shown in Note 11, “Stockholders' Equity” of Notes to the Consolidated Financial Statements appearing elsewhere herein.
(d)Stock Repurchases. In 2022, the Board of Directors approved adding 3,500,000 shares of Common Stock to an existing discretionary share repurchase authority. Under the share repurchase program, the Common Stock may be purchased through a combination of Rule 10b5-1 automatic trading plan and discretionary purchases in accordance with applicable securities laws. The number of shares purchased and the timing of the purchases will depend on a number of factors, including share price, trading volume and general market conditions, as well as working capital requirements, general business conditions and other factors, including alternative investment opportunities. The stock repurchase authorization remains effective until terminated by our Board of Directors which may occur at any time, subject to the parameters of any Rule 10b5-1 automatic trading plan that we may then have in effect. In 2022, we repurchased 6,647,895 shares at an average price of $60.70 per share and at a total cost of $403.5 million. As of December 31, 2022, there were 378,462 shares remaining on the existing repurchase authorization. On January 27, 2023, the Board of Directors approved adding 7,500,000 shares of common stock to the existing discretionary share repurchase authority. Including the additional shares, we have approximately 7.6 million shares available for repurchase as of the date of the Board of Directors' approval. We intend to spend approximately $200 million to repurchase Common Stock in 2023 through a combination of 10b5-1 plans and open-market purchases.
(e)Performance Graph. The following information in this Item 5 of this Annual Report on Form 10-K is not deemed to be “soliciting material” or to be “filed” with the SEC or subject to Regulation 14A or 14C under the Securities Exchange Act of 1934 or to the liabilities of Section 18 of the Securities Exchange Act of 1934, and will not be deemed to be incorporated by reference into any filing under the Securities Act of 1933 or the Securities Exchange Act of 1934, except to the extent we specifically incorporate it by reference into such a filing.

ITEM 7 – MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
OVERVIEW
Our company is comprised of two reporting segments: North America and Rest of World. Our Rest of World segment is primarily comprised of China, Europe and India. Both segments manufacture and market comprehensive lines of residential and commercial gas, heat pump and electric water heaters, boilers, tanks, and water treatment products. Both segments primarily manufacture and market in their respective region of the world.
Our sales in China in 2022 were impacted by lower consumer demand driven by COVID-19-related lockdowns. Certain COVID-19 restrictions were lifted in China at the end of 2022 and we believe that economic activity there will improve in 2023 as a result.
While supply chain and logistics challenges lingered in 2022, we saw improvement, particularly in the second half of the year. We remain in close contact with our suppliers and logistics providers to resolve supply chain constraints as they arise.
We continue to seek acquisitions that enable geographic growth, expand our core business, and establish adjacencies. Consistent with this strategy, we acquired Giant Factories, Inc. (Giant), a Canada-based manufacturer of residential and commercial water heaters, on October 19, 2021, for $199 million, subject to customary adjustments, using a combination of debt and cash. The acquisition fits squarely in our core capabilities, supplements our presence in Canada and enhances our capacity and distribution in the region. Giant contributed incremental sales of $94.3 million and $22.9 million in 2022 and 2021, respectively. Refer to Note 3, “Acquisitions” for additional information. We will also continue to look for opportunities to add to our existing operations in high growth regions demonstrated by our previous introductions of water treatment products in India and range hoods and cooktops in China.
In our North America segment, after approximately eight percent growth each year in 2021 and 2020, we believe that the wholesale residential water heater industry is returning to a more historical growth rate following a channel inventory destocking that occurred primarily in the third quarter of 2022, which resulted in a decrease in industry demand of 12 percent compared to 2021. We believe the majority of our customers exited 2022 with near normal inventory levels. While we believe that new home construction is in a deficit, we project it will be a headwind in 2023 and therefore, we project 2023 industry residential unit volumes will decrease approximately two to five percent from 2022. We believe that commercial water heater industry volumes will be flat to slightly up in 2023 compared to 2022 as supply chain constraints continue to ease. We expect to see a 10 to 12 percent increase in our sales of boilers in 2023 compared to 2022 due to industry growth of approximately three to four percent and our expectation that the transition to higher-efficiency boilers will continue. We anticipate sales of our North America water treatment products will increase approximately five to seven percent in 2023, compared to 2022, primarily driven by pricing and consumer demand.
In our Rest of World segment, we see the recent change to certain COVID-19 restrictions in China as a positive step to an improved economic environment. We project our sales in China will grow three to five percent in 2023 in local currency compared to 2022. Our guidance assumes volume will improve sequentially through out the year. We assume that the currency translation impact on sales will be similar to the 2022 and negatively impact sales by approximately four percent.
Combining all of these factors, we expect our 2023 consolidated sales to be flat to 2022, with a range of plus or minus three percent. Our guidance excludes the impacts from potential future acquisitions and assumes the COVID-19-related impacts in China improve in the second half of the year and do not have a significant impact on our productivity or significantly impact the end markets that we serve.

RESULTS OF OPERATIONS
In this section, we discuss the results of our operations for 2022 compared with 2021. We discuss our cash flows and current financial condition under “Liquidity and Capital Resources.” For a discussion related to 2021 compared with 2020, please refer to Item 7 of Part II, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the Year Ended December 31, 2021, which was filed with the United States Securities and Exchange Commission (SEC) on February 11, 2022, and is available on the SEC's website at www.sec.gov.

Our sales in 2022 were $3,753.9 million, or 6.1 percent higher than 2021 sales of $3,538.9 million. Higher sales in 2022 were primarily driven by the impacts of inflation-related pricing actions partially offset by lower residential water heater volumes in North America and lower sales in China. In addition, our sales were negatively impacted by approximately $61 million compared to last year due to the depreciation of foreign currencies against the U.S. dollar. Our acquisition of Giant added $94.3 million of incremental sales in 2022.
Our gross profit margin in 2022 of 35.4 percent declined compared to 37.0 percent in 2021. The lower gross margin in 2022 was primarily due to higher steel and other material costs and production inefficiencies, which outpaced the impact of our pricing actions.
Selling, general, and administrative (SG&A) expenses were $670.9 million in 2022, or $30.5 million lower than in 2021. The decrease in SG&A expenses was primarily due to the recognition of a gain from an $11.5 million judgment against a competitor related to its infringement of one of our patents, lower management incentive expenses, and lower engineering costs in China.
Interest expense was $9.4 million in 2022, compared to $4.3 million in 2021. The increase in interest expense in 2022 was primarily due to higher debt levels and interest rates.
In 2021, our Board of Directors approved the termination of our defined benefit pension plan (the Plan) with a termination date of December 31, 2021. The Plan represented over 95 percent of our pension plan liability. In the second quarter of 2022, we received a determination letter from the Internal Revenue Service (IRS) that allowed us to proceed with the termination process. In the fourth quarter of 2022, the settled Plan liabilities resulted in $417.3 million of pretax pension settlement expense, of which, $346.8 million was recorded in the North America segment and $70.5 million in Corporate Expense, and included $167.7 million in related tax benefits. For additional information, refer to the Critical Accounting Policies section under “Pensions” below.
Other expense (income)-net in 2022 was $425.6 million in expense compared to income of $20.4 million in 2021. In 2022, Other expense (income)-net reflected the $417.3 million pension settlement expense related to the termination of the Plan and $13.9 million in pension expenses compared to $12.0 million of pension income in 2021. To protect the Plan's funded status, the Plan transferred a significant portion of its assets to lower-risk investments in 2021. The impact of this transition resulted in a lower expected rate of return on pension investments and, accordingly, higher pension expenses in 2022 compared to the previous year. The service cost component of our pension income is reflected in cost of products sold and SG&A expenses. All other components of our pension expense (income) are reflected in other expense (income)-net.
19

Table of Contents
Our effective income tax rate in 2022 was lower than our effective income tax rate in 2021 primarily due to the tax effects of the pension settlement expense associated with the termination of the Plan, a non-recurring $4.2 million favorable tax impact recorded in the prior year periods related to amending a previously filed tax return and a change in geographic earnings mix. We estimate that our annual effective income tax rate for the full year of 2023 will be approximately 24 percent.
We are providing non-U.S. Generally Accepted Accounting Principles (GAAP) measures (adjusted earnings, adjusted EPS, adjusted segment earnings and adjusted corporate expense) that exclude the impact of the pension settlement expense as well as the income from the legal judgment, the expenses associated with a terminated acquisition and non-operating pension income and expenses. Reconciliations from GAAP measures to non-GAAP measures are provided in the Non-GAAP Measures section below. We believe that the measures of adjusted earnings, adjusted EPS, adjusted segment earnings and adjusted corporate expense provide useful information to investors about our performance and allow management and our investors to better understand our performance between periods without regard to items that we do not consider to be a component of our core operating performance or recurring in nature.
North America Segment
Years ended December 31 (dollars in millions)20222021
Net Sales$2,819.1 $2,529.5 
Segment Earnings266.0 590.8 
Segment Margin9.4 %23.4 %
Sales in our North America segment were $2,819.1 million in 2022, or $289.6 million higher than sales of $2,529.5 million in 2021. The increased sales in 2022 compared to the prior year were primarily driven by the price increases implemented in 2021, largely on water heaters, in response to rising material and other input costs and more than offset lower residential water heater volumes and unfavorable currency translation impact of approximately $12 million. In addition, our acquisition of Giant added $94.3 million of incremental sales in 2022.
North America segment earnings were $266.0 million in 2022, a decrease of 55 percent compared to segment earnings of $590.8 million in 2021. Segment margins were 9.4 percent and 23.4 percent in 2022 and 2021, respectively. Lower segment earnings and margin in 2022 were primarily due to the Plan settlement expense of $346.8 million, lower residential water heater volumes, higher material costs, and production inefficiencies, partially offset by price increases and the $11.5 million patent infringement judgment referenced above. Adjusted segment earnings and adjusted segment margin in 2022 were $611.0 million and 21.7 percent, respectively. Adjusted segment earnings and adjusted segment margin in 2021 were $580.3 million and 22.9 percent, respectively. We estimate our 2023 North America segment margin will be approximately 23 percent.
Adjusted segment earnings and adjusted segment margin in 2022 exclude the pension settlement expense of $346.8 million, pension expense of $9.7 million and the recognition of the $11.5 million patent infringement judgment. Adjusted segment earnings and adjusted segment margin in 2021 exclude pension income of $10.5 million.
Rest of World Segment
Years ended December 31 (dollars in millions)20222021
Net Sales$965.8 $1,036.5 
Segment Earnings96.3 91.4 
Segment Margin10.0 %8.8 %
Rest of World sales of $965.8 million decreased seven percent year-over-year, including an unfavorable currency translation impact of approximately $49 million, of which $36 million related to sales in China. In local currency, segment sales decreased by approximately two percent year-over-year. The decrease in sales in 2022 was primarily driven by lower consumer demand in China due to COVID-19-related disruptions and lockdowns. Sales in India increased 28 percent in local currency in 2022 due to strong demand for our water heater and water treatment products.
Rest of World segment earnings were $96.3 million in 2022 compared to $91.4 million in 2021. Segment margins were 10.0 percent and 8.8 percent in 2022 and 2021, respectively. Compared to 2021, higher segment earnings and margin were primarily driven by lower engineering, advertising, and selling expenses in China. We expect the full-year segment margin to be approximately 10 percent in 2023.

LIQUIDITY AND CAPITAL RESOURCES
Our working capital was $699.5 million at December 31, 2022 compared with $633.8 million at December 31, 2021. A majority of the increase in working capital was driven by lower accounts payable and payroll-related accruals and higher inventory balances than at December 31, 2021, due to higher levels of safety stock which were partially offset by lower accounts receivable, and cash balances. In addition, cash balances as of December 31, 2022 were negatively impacted by $20.8 million due to the effects of changes in foreign currency during the year. In 2022, we repatriated approximately $120 million of cash from our foreign subsidiaries to the U.S. We used the proceeds to pay down outstanding debt balances.
Years ended December 31 (dollars in millions)20222021
Cash provided by operating activities$391.4 $641.1 
Cash provided by (used in) investing activities8.1 (349.9)
Cash used in financing activities(430.8)(421.0)
Cash provided by operating activities in 2022 was $391.4 million compared with $641.1 million during 2021. The decrease in operating cash flows in 2022 was primarily due to lower customer deposits in China, higher 2021-related incentive payments made in 2022 and additional working capital cash outlays primarily related to higher cost inventories that more than offset lower accounts receivable balances. Our free cash flow in 2022 and 2021 was $321.1 million and $566.0 million, respectively. We expect free cash flow to be between $550 million to $600 million in 2023. Free cash flow is a non-GAAP measure and is described in more detail in the Non-GAAP Measures section below.
Our capital expenditures were $70.3 million in 2022 and $75.1 million in 2021. We project our 2023 capital expenditures will be between $70 and $75 million and expect depreciation and amortization will be approximately $70 million.
In 2021, we renewed and amended our $500 million revolving credit facility, which now expires on April 1, 2026. The renewed and amended facility, with a group of nine banks, has an accordion provision that allows it to be increased up to $850 million if certain conditions (including lender approval) are satisfied. Borrowing rates under the facility are determined by our leverage ratio. The facility requires us to maintain two financial covenants, a leverage ratio test and an interest coverage test, and we were in compliance with the covenants as of December 31, 2022, and expect to be in compliance for the foreseeable future.
The facility backs up commercial paper and credit line borrowings. At December 31, 2022, we had $208 million outstanding under the facility and an available borrowing capacity of $292 million. We believe the combination of available borrowing capacity and operating cash flows will provide sufficient funds to finance our existing operations for the foreseeable future.
Our total debt increased by $150.6 million in 2022 and was primarily due to repurchases of our common stock. Our leverage, as measured by the ratio of total debt to total capitalization, was 16.5 percent at December 31, 2022, compared with 9.7 percent at December 31, 2021.
Our remaining U.S. pension plan continues to meet all funding requirements under ERISA regulations. We were not required to make a contribution to our pension plan in 2022. We forecast that we will not be required to make a contribution to the plan in 2023, and we do not plan to make any voluntary contributions in 2023. For further information on our pension plans, see the Critical Accounting Policies below and Note 13, “Pension and Other Post-retirement Benefits” of Notes to the Consolidated Financial Statements.
In 2022, our Board of Directors approved adding 3,500,000 shares of common stock to our existing discretionary share repurchase authority. Under our share repurchase program, we may purchase our common stock through a combination of a Rule 10b5-1 automatic trading plan and discretionary purchases in accordance with applicable securities laws. The stock repurchase authorization remains effective until terminated by our Board of Directors, which may occur at any time, subject to the parameters of any Rule 10b5-1 automatic trading plan that we may then have in effect. During 2022, we repurchased 6,647,895 shares of our stock at a total cost of $403.5 million. As of December 31, 2022, we had 378,462 shares remaining on the share repurchase authority. On January 27, 2023, the Board of Directors approved adding 7,500,000 shares of common stock to the existing discretionary share repurchase authority. Including the additional shares, we have approximately 7.6 million shares available for repurchase as of the date of the Board of Directors' approval. We intend to repurchase approximately $200 million of our common stock in 2023 through a combination of 10b5-1 plans and open-market purchases.

Recent Accounting Pronouncements
Refer to Recent Accounting Pronouncements in Note 1, “Organization and Significant Accounting Policies” of Notes to the Consolidated Financial Statements.
Critical Accounting Policies
Our accounting policies are described in Note 1, “Organization and Significant Accounting Policies” of Notes to the Consolidated Financial Statements. Also as disclosed in Note 1, the preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires the use of estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Future events and their effects cannot be determined with absolute certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results inevitably will differ from those estimates, and such differences may be material to the financial statements.
The most significant accounting estimates inherent in the preparation of our financial statements include estimates associated with the evaluation of the impairment of goodwill and indefinite-lived intangible assets, as well as significant estimates used in the determination of liabilities related to warranty, product liability and pensions. Various assumptions and other factors underlie the determination of these significant estimates. The process of determining significant estimates is fact-specific and takes into account factors such as historical experience and trends, and in some cases, actuarial techniques. We monitor these significant factors and adjustments are made as facts and circumstances dictate. Historically, actual results have not significantly deviated from those determined using the estimates described above.
Goodwill and Indefinite-lived Intangible Assets
In conformity with GAAP, goodwill and indefinite-lived intangible assets are tested for impairment annually or more frequently if events or changes in circumstances indicate that the assets might be impaired. We perform impairment reviews for our reporting units using a fair-value method based on management’s judgments and assumptions. The fair value represents the estimated amount at which a reporting unit could be bought or sold in a current transaction between willing parties on an arms-length basis. The estimated fair value is then compared with the carrying amount of the reporting unit, including recorded goodwill. We are subject to financial statement risk to the extent that goodwill and indefinite-lived intangible assets become impaired. Any impairment review is, by its nature, highly judgmental as estimates of future sales, earnings and cash flows are utilized to determine fair values. However, we believe that we conduct a thorough and competent annual quantitative analysis of goodwill and indefinite-lived intangible assets. Based on the annual goodwill impairment test, we determined there was no impairment of our goodwill as of December 31, 2022. The fair value of each of our reporting units significantly exceeded its carrying value and a 20% decrease in the estimated fair value of our reporting units would not have resulted in a different conclusion. Based on the annual indefinite-lived assets impairment test, we determined there was no impairment of our indefinite-lived assets as of December 31, 2022.
Product Warranty
Our products carry warranties that generally range from one to 12 years and are based on terms that are generally accepted in the market. We provide for the estimated cost of product warranty at the time of sale. The product warranty provision is estimated based upon warranty loss experience using actual historical failure rates and estimated costs of product replacement. The variables used in the calculation of the provision are reviewed at least annually. At times, warranty issues may arise which are beyond the scope of our historical experience. We provide for any such warranty issues as they become known and estimable. While our warranty costs have historically been within calculated estimates, it is possible that future warranty costs could differ significantly from those estimates. The allocation of the warranty liability between current and long-term is based on the expected warranty liability to be paid in the next year as determined by historical product failure rates. At December 31, 2022 and 2021, our reserve for product warranties was $182.5 million and $184.4 million, respectively.
Pensions
We have significant pension benefit costs that are developed from actuarial valuations. The valuations reflect key assumptions regarding, among other things, discount rates, expected return on plan assets, retirement ages, and years of service. Consideration is given to current market conditions, including changes in interest rates in making these assumptions.
22

Table of Contents
Our assumption for the expected return on plan assets was 3.12 and 6.25 percent in 2022 and 2021, respectively. The discount rate used to determine net periodic pension costs increased to 2.80 percent in 2022 from 2.47 percent in 2021. For 2023, our expected return on plan assets is 5.25 percent and our discount rate is 5.13 percent.
In developing our expected return on plan assets, we evaluate our pension plan’s current and target asset allocation, the expected long-term rates of return of equity and bond indices and the actual historical returns of our pension plan. Our plan’s target allocation to bonds managers is between 60 to 95 percent with the remainder allocated primarily to equities, private equity managers and cash. Our actual asset allocation as of December 31, 2022, was eight percent to equity managers, 27 percent to bond managers, five percent to private equity managers, and the remainder allocated to cash. We regularly review our actual asset allocation and periodically rebalance our investments to our targeted allocation when considered appropriate. Our pension plan’s historical ten-year and 25-year compounded annualized returns are 7.1 percent and 6.9 percent, respectively. We believe that with our target allocation and the expected long-term returns of equity and bond indices as well as our actual historical returns, our 5.25 percent expected return on plan assets for 2023 is reasonable.
The discount rate assumptions used to determine future pension obligations at December 31, 2022 and 2021 were based on the Aon AA Only Above Median yield curve, which was designed by Aon to provide a means for plan sponsors to value the liabilities of their postretirement benefit plans. The AA Only Above Median yield curve represents a series of annual discount rates from bonds with AA minimum average rating as rated by Moody’s Investor Service, Standard & Poor’s and Fitch Ratings. We will continue to evaluate our actuarial assumptions at least annually, and we will adjust the assumptions as necessary.
Lowering the expected return on plan assets by 25 basis points would increase our net pension expense for 2022 by approximately $1.8 million. Lowering the discount rate by 25 basis points would decrease our 2022 net pension expense by approximately $0.8 million.
In 2021, our Board of Directors approved the termination of our defined benefit pension plan (the Plan) with a termination date of December 31, 2021. The Plan represented over 95 percent of our pension plan liability. In the second quarter of 2022, we received a determination letter from the IRS that allowed us to proceed with the termination process. In the fourth quarter of 2022, we settled approximately $169 million of Plan liabilities through lump-sum payments from existing plan assets to eligible participants who elected to receive them and settled approximately $463 million of Plan liabilities by entering into an agreement to purchase annuities from Mass Mutual Life Insurance Company (MML). The irrevocable agreement with MML covers approximately 7,000 active and former employees and their beneficiaries, with MML assuming the future annuity payments for these individuals commencing March 1, 2023. These settlements resulted in approximately $417.3 million of pretax expense in 2022, partially offset by approximately $167.7 million in related tax benefits.

Non-GAAP Measures
We are providing non-U.S. Generally Accepted Accounting Principles (GAAP) measures (adjusted earnings, adjusted EPS, adjusted segment earnings and adjusted corporate expense) that exclude the impact of pension settlement expense as well as legal judgment income, expenses associated with a terminated acquisition and non-operating pension income and expenses. Reconciliations from GAAP measures to non-GAAP measures are provided below.
We believe that the measures of adjusted earnings, adjusted EPS, adjusted segment earnings and adjusted corporate expense provide useful information to investors about our performance and allow management and our investors to better understand our performance between periods without regard to items that we do not consider to be a component of our core operating performance or recurring in nature.

Outlook
As we begin 2023, we expect our consolidated sales to be flat to 2022 with a range of plus or minus three percent. Our sales projection is driven by expected lower industry residential unit volumes in North America and offset by anticipated increased boiler and water treatment sales in North America and higher sales in China. We expect to achieve full-year earnings of between $3.15 and $3.45 per share. Our guidance excludes the impacts from potential future acquisitions and assumes the COVID-19-related impacts in China improve in the second half of the year and do not have a significant impact on our productivity or significantly impact the end markets that we serve.
OTHER MATTERS
Environmental
Our operations are governed by a number of federal, foreign, state, local and environmental laws concerning the generation and management of hazardous materials, the discharge of pollutants into the environment and remediation of sites owned by the Company or third parties. We have expended financial and managerial resources complying with such laws. Expenditures related to environmental matters were not material in 2022 and we do not expect them to be material in any single year. We have reserves associated with environmental obligations at various facilities and we believe these reserves together with available insurance coverage are sufficient to cover reasonably anticipated remediation costs. Although we believe that our operations are substantially in compliance with such laws and maintain procedures designed to maintain compliance, there are no assurances that substantial additional costs for compliance will not be incurred in the future. However, since the same laws govern our competitors, we should not be placed at a competitive disadvantage.

Risk Management
We evaluate risk to our business in a number of ways, primarily through our Enterprise Risk Management (ERM) process, which we conduct enterprise-wise on a periodic basis, and seeks to identify and address significant and material risks. Our ERM process assesses, manages, and monitors risks consistent with the integrated risk framework in the Enterprise Risk Management-Integrated Framework (2017) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). We believe that risk-taking is an inherent aspect of the pursuit of our strategy. Our goal is to manage risks prudently rather than avoid risks. We can mitigate risks and their impact on our company only to a limited extent.
A team of senior executives prioritizes identified risks, including decarbonization, new technologies and cyber threats among others, and assigns an executive to address each major identified risk area and lead action plans to manage risks. Our Board of Directors provides oversight of the ERM process and reviews significant identified risks. The Audit Committee of the Board of Directors also reviews significant financial risk exposures and the steps management has taken to monitor and manage them. Our other Board committees also play a role in risk management, as set forth in their respective charters.
Our goal is to proactively manage risks using a structured approach in conjunction with strategic planning, with the intent to preserve and enhance shareholder value. However, the risks set forth in Item 1A - Risk Factors and elsewhere in this Annual Report on Form 10-K and other risks and uncertainties could adversely affect us and cause our results to vary materially from recent results or from our anticipated future results.
Market Risk
We are exposed to various types of market risks, primarily currency. We monitor our risks in such areas on a continuous basis and generally enter into forward contracts to minimize such exposures. We do not engage in speculation in our derivatives strategies. Further discussion regarding derivative instruments is contained in Note 1, “Organization and Significant Accounting Policies” of Notes to Consolidated Financial Statements.
We enter into foreign currency forward contracts to minimize the effect of fluctuating foreign currencies. At December 31, 2022, we had net foreign currency contracts outstanding with notional values of $122.7 million. Assuming a hypothetical ten percent movement in the respective currencies, the potential foreign exchange gain or loss associated with the change in exchange rates would amount to $12.3 million. However, gains and losses from our forward contracts will be offset by gains and losses in the underlying transactions being hedged.

The Board of Directors and Stockholders
A. O. Smith Corporation
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of A. O. Smith Corporation (the Company) as of December 31, 2022 and 2021, the related consolidated statements of earnings, comprehensive earnings, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2022, and the related notes and financial statement schedule listed in the index at Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 14, 2023 expressed an unqualified opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosure to which it relates.
Product Warranty Liability Valuation
Description of the Matter

At December 31, 2022, the Company’s product warranty liability was $182.5 million. As discussed in Note 1 of the consolidated financial statements, the Company records a liability for the expected cost of warranty-related claims at the time of sale. The product warranty liability is estimated based upon warranty loss experience using actual historical failure rates and estimated cost of product replacement. Products generally carry warranties from one to twelve years. The Company performs separate warranty calculations based on the product type and the warranty term and aggregates them.

Auditing the product warranty liability was complex due to the judgmental nature of the warranty loss experience assumptions, including the estimated product failure rate and the estimated cost of product replacement. In particular, it is possible that future product failure rates may not be reflective of historical product failure rates, or that a product quality issue has not yet been identified as of the financial statement date. Additionally, the cost of product replacement could differ from estimates due to fluctuations in the replacement cost of the product.
How We Addressed the Matter in our Audit
We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over the Company’s product warranty liability calculation. For example, we tested controls over management’s review of the product warranty liability calculation, including the significant assumptions and the data inputs to the calculation.
  
To test the Company’s calculation of the product warranty liability, our audit procedures included, among others, evaluating the methodology used, and testing the significant assumptions discussed above and the underlying data used by the Company in its analysis. We tested the validity and categorization of claims by product type and warranty period within the calculation and tested the completeness and accuracy of the claims data. We recalculated the historical failure rates using actual claims data. We compared the estimated cost of replacement included in the product warranty liability with the current costs to manufacture a comparable product and assessed the impact of projected changes in significant product costs. We also analyzed current year claims data to identify changes in failure trends and assessed the historical accuracy of the prior year liability. Further, we inquired of operational and quality control personnel regarding quality issues and trends.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Organization and Significant Accounting Policies
Organization. A. O. Smith Corporation (A. O. Smith or the Company) is comprised of two reporting segments: North America and Rest of World. The Rest of World segment is primarily comprised of China, Europe and India. Both segments manufacture and market comprehensive lines of residential and commercial gas and electric water heaters, boilers, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world.
Consolidation. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries after elimination of intercompany transactions.
Use of estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States (U.S.) requires management to make estimates and assumptions that affect the amounts reported in the accompanying financial statements and notes. Actual results could differ from those estimates.
Fair value of financial instruments. The carrying amounts of cash, cash equivalents, marketable securities, receivables, floating rate debt and trade payables approximated fair value as of December 31, 2022 and 2021, due to the short maturities or frequent rate resets of these instruments. The fair value of term notes with insurance companies included in Long-term debt within the consolidated balance sheets was approximately $120.2 million as of December 31, 2022 compared with the carrying amount of $136.5 million for the same date. The fair value of term notes with insurance companies was approximately $128.4 million as of December 31, 2021 compared with the carrying amount of $145.9 million.
Foreign currency translation. For all subsidiaries outside the U.S., with the exception of its Barbados, Hong Kong and Mexican companies and its non-operating companies in the Netherlands, the Company uses the local currency as the functional currency. For those operations using a functional currency other than the U.S. dollar, assets and liabilities were translated into U.S. dollars at year-end exchange rates, and revenues and expenses were translated at weighted-average exchange rates. The resulting translation adjustments were recorded as a separate component of stockholders’ equity. The Barbados, Hong Kong, Mexican and non-operating Netherlands companies use the U.S. dollar as the functional currency. Gains and losses from foreign currency transactions were included in net earnings and were not significant in 2022, 2021, or 2020.
Cash and cash equivalents. The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
Marketable securities. The Company considers all highly liquid investments with maturities greater than 90 days when purchased to be marketable securities. At December 31, 2022, the Company’s marketable securities consisted of bank time deposits with original maturities ranging from 180 days to 12 months and were primarily located at investment grade rated banks in China and Hong Kong.
Inventory valuation. Inventories are carried at lower of cost or net realizable value. Cost is determined on the last-in, first-out (LIFO) method for a majority of the Company’s domestic inventories, which comprised 36 percent and 37 percent of the Company’s total inventory at December 31, 2022 and 2021, respectively. Inventories of foreign subsidiaries, the remaining domestic inventories and supplies were determined using the first-in, first-out (FIFO) method.
Property, plant and equipment. Property, plant and equipment are stated at cost. Depreciation is computed primarily by the straight-line method. The estimated service lives used to compute depreciation are generally 25 to 50 years for buildings, three to 20 years for equipment and three to 15 years for software. Maintenance and repair costs are expensed as incurred.
Goodwill and other intangibles. Goodwill and indefinite-lived intangible assets are not amortized but are reviewed for impairment on an annual basis. Separable intangible assets, primarily comprised of customer relationships, that are not deemed to have an indefinite life are amortized on a straight-line basis over their estimated useful lives which range from five to 25 years.
Impairment of long-lived and amortizable intangible assets. Property, plant and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset or group of assets, a loss is recognized for the difference between the fair value and carrying value of the asset or group of assets. Such analyses involves significant judgment.
Product warranties. The Company’s products carry warranties that generally range from one to twelve years and are based on terms that are consistent with the market. The Company records a liability for the expected cost of warranty-related claims

at the time of sale and is estimated based on the warranty period, product type and loss experience using actual historical failure rates and estimated costs of product replacement. The variables used in the calculation of the provision are reviewed by the Company at least annually. At times, warranty issues may arise which are beyond the scope of the Company’s historical experience. The Company provides for any such warranty issues as they become known and estimable. The allocation of the warranty liability between current and long-term is based on expected warranty claims to be paid in the next year as determined by historical product failure rates.
The following table presents the Company’s product warranty liability activity in 2022 and 2021:
Years ended December 31 (dollars in millions)20222021
Balance at beginning of year$184.4 $142.3 
Expense64.2 81.2 
Claims settled(66.1)(51.3)
Acquired obligations 12.2 
Balance at end of year$182.5 $184.4 
Derivative instruments. The Company utilizes certain derivative instruments to enhance its ability to manage currency as well as raw materials price risk. The Company does not enter into contracts for speculative purposes. The fair values of all derivatives are recorded in the consolidated balance sheets. The change in a derivative’s fair value is recorded each period in current earnings or accumulated other comprehensive loss (AOCL), depending on whether the derivative is designated as part of a hedge transaction and if so, the type of hedge transaction. See Note 14, “Derivative Instruments” for disclosure of the Company’s derivative instruments and hedging activities.
Fair Value Measurements. Accounting Standards Codification (ASC) 820 Fair Value Measurements, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
Assets and liabilities measured at fair value are based on the market approach which are prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.
Assets (liabilities) measured at fair value on a recurring basis are as follows (dollars in millions):
Fair Value Measurement UsingBalance Sheet LocationDecember 31, 2022December 31, 2021
Quoted prices in active markets for identical assets (Level 1) Marketable Securities $90.6 $188.1 
Significant other observable inputs (Level 2)Other current assets / Accrued liabilities6.5 (0.7)
There were no changes in the valuation techniques used to measure fair values on a recurring basis.
Revenue recognition. Substantially all of the Company’s sales are from contracts with customers for the purchase of its products. Contracts and customer purchase orders are used to determine the existence of a sales contract. Shipping documents are used to verify shipment. For substantially all of its products, the Company transfers control of products to the customer at the point in time when title and risk are passed to the customer, which generally occurs upon shipment of the product. See Note 2, “Revenue Recognition” for disclosure of the Company’s revenue recognition activities. 
Advertising. The majority of advertising costs are charged to operations as incurred and totaled $100.4 million, $107.0 million and $97.0 million during 2022, 2021 and 2020, respectively. Included in total advertising costs are expenses associated with store displays for water heater, water treatment products, range hood and cook tops in China that are amortized over 12 to 48 months which totaled $17.2 million, $25.2 million and $27.0 million during 2022, 2021 and 2020, respectively.

Research and development. Research and development costs are charged to operations as incurred and amounted to $89.0 million, $94.2 million and $80.7 million during 2022, 2021 and 2020, respectively.
Environmental costs. The Company accrues for costs associated with environmental obligations when such costs are probable and reasonably estimable. Costs of estimated future expenditures are not discounted to their present value. Recoveries of environmental costs from other parties are recorded as assets when their receipt is considered probable. The accruals are adjusted as facts and circumstances change.
Stock-based compensation. Compensation cost is recognized using the straight-line method over the vesting period of the award and forfeitures are recognized as they occur. In accordance with amended ASC 718, the Company recognized $1.1 million, $5.6 million, and $4.2 million of discrete income tax benefits on settled stock based compensation awards during 2022, 2021, and 2020 respectively.
Income taxes. The provision for income taxes is computed using the asset and liability method, in accordance with ASC 740 Income Taxes, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities and for operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled and are classified as noncurrent in the consolidated balance sheet. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized.
The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon settlement.
Earnings per share of common stock. The Company is not required to use the two-class method of calculating earnings per share since its Class A Common Stock and Common Stock have equal dividend rights. The numerator for the calculation of basic and diluted earnings per share is net earnings. The following table sets forth the computation of basic and diluted weighted-average shares used in the earnings per share calculations:

Recent Accounting Pronouncements.
In November 2021, the Financial Accounting Standards Board (FASB) amended ASC 832, Government Assistance (issued under Accounting Standards Update (ASU) 2021-10, “Disclosures by Business Entities about Government Assistance”). This amendment requires disclosures that are expected to increase the transparency of transactions with a government accounted for by applying a grant or contribution accounting model by analogy, including (1) the types of transactions, (2) the accounting for those transactions, and (3) the effect of those transactions on an entity’s financial statements. The Company adopted the amendment on January 1, 2022, and the adoption of ASU 2021-10 did not impact its annual disclosures, consolidated balance sheets, statements of earnings or statements of cash flows.
2. Revenue Recognition
Substantially all of the Company’s sales are from contracts with customers for the purchase of its products. Contracts and customer purchase orders are used to determine the existence of a sales contract. Shipping documents are used to verify shipment. For substantially all of its products, the Company transfers control of products to the customer at the point in time when title and risk are passed to the customer, which generally occurs upon shipment of the product. Each unit sold is considered an independent, unbundled performance obligation. The Company’s sales arrangements do not include other performance obligations that are material in the context of the contract. 
The nature, timing and amount of revenue for a respective performance obligation are consistent for each customer. The Company measures the sales transaction price based upon the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. Sales and value added taxes are excluded from the measurement of the transaction price. The Company’s payment terms for the majority of its customers are 30 to 90 days from shipment.

2. Revenue Recognition (continued)
Additionally, certain customers in China pay the Company prior to the shipment of products resulting in a customer deposits liability of $85.7 million and $155.2 million at December 31, 2022 and December 31, 2021, respectively. Customer deposit liabilities are short term in nature, recognized into revenue within one year of receipt. The Company assesses the collectability of customer receivables based on the creditworthiness of a customer as determined by credit checks and analysis, as well as the customer’s payment history. In determining the allowance for credit losses, the Company also considers various factors including the aging of customer accounts and historical write-offs. In addition, the Company monitors other risk factors including forward-looking information when establishing adequate allowances for credit losses, which reflects the current estimate of credit losses expected to be incurred over the life of the receivables. The Company’s allowance for credit losses was $9.5 million at both December 31, 2022 and December 31, 2021.
Rebates and incentives are based on pricing agreements and are tied to sales volume. The amount of revenue is reduced for variable consideration related to customer rebates which are calculated using expected values and are based on program specific factors such as expected rebate percentages based on expected volumes. In situations where the customer has the right to return eligible products, the Company reduces revenue for its estimates of expected product returns, which are primarily based on an analysis of historical experience. Changes in such accruals may be required if actual sales volume differs from estimated sales volume or if future returns differ from historical experience. Shipping and handling costs billed to customers are included in net sales and the related costs are included in cost of products sold and are activities performed to fulfill the promise to transfer products.
Disaggregation of Net Sales
The Company is comprised of two reporting segments: North America and Rest of World. The Rest of World segment is primarily comprised of China, Europe and India. Both segments manufacture and market comprehensive lines of residential and commercial gas, heat pump and electric water heaters, boilers, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world.
As each segment manufactures and markets products in its respective region of the world, the Company has determined that geography is the primary factor in reporting its sales. The Company further disaggregates its North America segment sales by major product line as each of North America’s major product lines is sold through distinct distribution channels and these product lines may be impacted differently by certain economic factors. Within the Rest of World segment, particularly in China and India, the Company’s major customers purchase across the Company’s product lines, utilizing the same distribution channels regardless of product type. In addition, the impact of economic factors is unlikely to be differentiated by product line in the Rest of World segment.
