## PART 1

## ITEM 1 - BUSINESS

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 and electric water heaters, boilers, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world. Our Rest of World segment also manufactures and markets in-home air purification products in China.

## NORTH AMERICA

We serve residential and commercial end markets in North America with a broad range of products including:

Water heaters. Our residential and commercial water heaters come in sizes ranging from 2.5 gallon (point-of-use) models to 4,000 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 and motels, office buildings, laundries, car washes and small businesses.

Boilers. Our residential and commercial boilers range in size from 45,000 British Thermal Units (BTUs) to 6.0 million BTUs. Our boilers are primarily used in space heating applications for residences, hospitals, schools, hotels and other large commercial buildings.

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 and Water-Right, Inc. (Water-Right) in 2019. 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 complete line of food and beverage filtration products. Typical applications for our water treatment products include residences, restaurants, hotels and offices. A portion of our sales of water treatment products is comprised of replacement filters.

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 markets. In the commercial markets for both water heating and space heating, we believe our comprehensive product lines and our high-efficiency products give us a competitive advantage in these portions of the markets. Our wholesale distribution channel, where we sell our products primarily under the A. O. Smith and State brands, includes more than 1,300 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 Lochnivar brand is one of the leading residential and commercial boiler brands in the U.S. Approximately 40 percent of Lochnivar branded sales consist of residential and commercial water heaters while the remaining 60 percent of Lochnivar-branded sales consist primarily of boilers and related parts. Our commercial boiler distribution channel is primarily comprised of manufacturer representative firms, the remainder of our Lochnivar branded products are distributed through wholesale channels.

We sell our Aquasana branded products primarily directly to consumers through e-commerce as well as on-line retailers including Amazon and through other retail chains. Our water softener branded products and problem well water solutions, which include Hague, WaterBoss, Water-Right, WaterCare, and Evolve, are sold through water quality dealers. Our water softener products are also sold through home center retail chains. Our A. O. Smith branded water treatment products are sold through Lowe's and our wholesale distribution channels.

Our energy-efficient product offerings continue to be a sales driver for our business. Our commercial water heaters and our condensing 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.



## Table of Contents

We sell our water heating 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, Rinna, Aerco and Navien. Numerous other manufacturing companies also compete. Our principal water treatment competitors in the U.S. are Brita, Culligan, Kinetico, Pentair and Ecowater as well as numerous regional assemblers.

## REST OF WORLD

We have operated in China for more than 20 years. In that time, we have been aggressively expanding our presence while building A. O. Smith brand recognition in the residential and commercial markets. 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 leading suppliers of water heaters to the residential market in China in dollar terms. We manufacture and market water treatment products, primarily residential reverse osmosis products. We also manufacture and market air purification products as well as range hoods and cooktops in China.

We sell water heaters in approximately 9,000 retail outlets in China, of which over 2,600 exclusively sell our products. Our water treatment products and air purification products are sold in over 8,100 and 3,300 retail outlets in China, respectively.

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.

Our primary competitors in China in the electric water heater market segment are Haier and Midea, which are Chinese companies. We compete with Rinnai and Noritz in the gas tankless water heater market segment. Our principal competitors in the water treatment market are Qinyuan, Angel, Midea and Xiaomi. Our principal competitors in the China air purification market are Phillips, Panasonic and Sharp. In India, we compete with Bajaj and Havels in the water heater market and Eureka Forbes, Kent and Hindustan Unilever in the water treatment market.

In addition, we sell water heaters in the European and Middle Eastern markets and water treatment products in Hong Kong, Turkey and Vietnam, all of which combined comprised less than eight percent of total Rest of World sales in 2019.

## RAW MATERIALS

Raw materials for our manufacturing operations, primarily consisting of steel, are generally available in adequate quantities. A portion of our customers are contractually obligated to accept price changes based on fluctuations in steel prices. There has been volatility in steel costs over the last several years.

## RESEARCH AND DEVELOPMENT

To improve our competitiveness by generating new products and processes, we conduct research and development at our newly constructed 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 2019, 2018 and 2017 were $87.9 million, $94.0 million and $86.4 million, respectively.

## PATENTS AND TRADEMARKS

We own and use in our businesses various trademarks, trade names, patents, trade secrets and licenses. We do not believe that our business as a whole is materially dependent upon any such trademark, trade name, patent, trade secret or license. However, our trade name is important with respect to our products, particularly in China, India and the U.S.

## EMPLOYEES

We employed approximately 15,100 employees as of December 31, 2019, primarily non-union.

## BACKLOG

Due to the short-cycle nature of our businesses, none of our operations sustain significant backlogs.



## Table of Contents

## ENVIRONMENTAL LAWS

Our operations are governed by a variety of federal, foreign, state and local laws intended to protect the environment. Compliance with 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

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 actually occurs, 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. The risks and uncertainties below are not the only risks facing our company.

## • The effects of a global economic downturn could have a material adverse effect on our business

Global economic growth remains uneven and could stall or reverse course. If this was to occur it 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, or slower adoption of energy-efficient water heaters and boilers, or high quality water treatment products, which could negatively impact our profitability and cash flows. In addition, a deterioration in current economic conditions due to many factors or fears including public health crises, such as the current coronavirus concerns originating in China, 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.

## • A portion of our business could be affected by further weakening of the Chinese economy

Approximately 28 percent of our net sales in 2019 were attributable to China. Our sales in China decreased in 2019 compared to 2018 and 2017. We believe that decrease was due to weaker end-market demand as a result of a weakening Chinese economy, elevated channel inventory levels, and a higher mix of mid-price products versus premium price products. We derive a substantial portion of our sales in China from premium-tier products. Changes in consumer preferences, weakening consumer confidence and sentiment as well as economic uncertainty, including the unknown impact from the coronavirus, may prompt consumers there 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.

## • 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 nine percent of the residential market segment in 2019, 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.

## • Our business could be adversely impacted by changes in consumer purchasing behavior, consumer preferences and technological changes

Consumer preferences for products and the methods in which they purchase products are constantly changing based on, among other factors, cost, convenience, environmental and social concerns and perceptions. Consumer purchasing behavior may shift the product mix in the markets we participate in or result in a shift to new distribution channels, including e-commerce, which continues to expand. For example, consumer preferences may shift toward more efficient gas products or electric powered products due to the increased attention on the impact of greenhouse gas emissions on the environment. In addition, technologies are ever changing. Our ability to timely develop and successfully market new products and to develop, acquire, and retain 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 to align with consumer purchasing behavior and consumer preferences, which could materially and adversely affect our financial condition, results of operations and cash flows.



## Table of Contents

• 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, our employees, facilities, suppliers, distributors, or customers. Extraordinary events, including natural disasters, political disruptions, terrorist attacks, public health issues, and acts of war may disrupt our business and operations, 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. One of our manufacturing plants is located within a floodplain that has experienced past flooding events. We also have other manufacturing facilities located in hurricane and earthquake zones. 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. In addition, 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. For example, a strain of coronavirus surfaced in Wuhan, China and has led to store closures and a decrease of consumer traffic in China. While not yet quantifiable, we expect the effects of the coronavirus to have a material adverse impact on our operating results for the first quarter of 2020 and we continue to assess the financial impact for the remainder of 2020.

• 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 36 percent of our net sales in 2019 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 8,800 of our 15,100 employees as of December 31, 2019 were located in China. At December 31, 2019, approximately $549 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 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

Net sales to our five largest customers represented approximately 39 percent of our sales in 2019. 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. 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 decline in North American new residential and commercial construction or a decline in replacement related volume

Residential and commercial construction activity in North America has shown modest growth which could decline in the future. We believe that the significant majority of the markets we serve are for replacement of existing products, and residential water heater replacement volume was strong in 2017 and 2018 before declining in 2019. Changes in the replacement volume and in the construction market in North America could negatively affect us.



## Table of Contents

## • 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 $443 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 or global exchange rate instability or volatility that strengthens the U.S. dollar against foreign currencies. As a result, an increase in the value of the U.S. dollar relative to the local currencies of our foreign markets has had and would continue to have a negative effect on our profitability. In addition to currency translation risks, we incur a currency transaction risk whenever one of our subsidiaries enters into either 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 which we manufacture in the U.S, and to a lesser extent from component purchases in Europe and payroll in Mexico. These risks may hurt our reported sales and profits in the future or negatively impact revenues and earnings translated from foreign currencies into U.S. dollars.

## • Changes in regulations or standards 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. While we believe our products are currently efficient, safe and environment-friendly, a significant change to regulatory requirements (whether federal, foreign, state or local) such as a transition to alternative energy sources as a replacement for gas combustion, or to industry standards, could substantially increase manufacturing 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.

## • 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.

## • Our operations could be adversely impacted by material price volatility and supplier concentration

The market prices for certain raw materials we purchase, primarily steel, have been volatile. Significant increases in the cost of any of the key materials we purchase could 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 addition, 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.

• 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, like those of other companies, 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,



## Table of Contents

malicious insiders or breaches of security. We have a response plan in place in the event of a data breach and we continue to take steps 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. However, any operations failure or breach of security from increasingly sophisticated cyber threats 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 and have a material adverse effect on our financial condition, results of operations and cash flows and our reputation.

• 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 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.

• Our success is dependent on developing and retaining highly qualified personnel

Attracting and retaining talented employees is important to the continued success and growth of our business. Failure to retain key personnel, particularly on the leadership team, could have a material effect on our business and our ability to execute our business strategies in a timely and effective manner.

• Sales growth of our boilers could stall resulting in lower than expected revenues and earnings

The compound annual growth rate of our boiler sales has been approximately eight percent per year since our acquisition of Lochinvar in 2011, largely due to the transition in the boiler industry in the U.S. from lower efficiency, non-condensing boilers to higher efficiency, higher priced, condensing boilers, as well as new product introductions. We expect the transition to condensing boilers to continue, but if the transition to higher efficiency, higher priced, condensing boilers stalls as a result of lower energy costs, a U.S. recession occurs, or our competitors' technologies surpass our technology, our growth rate could be lower than expected and have a material adverse effect 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 will continue to evaluate potential acquisitions, and we could use a significant portion of our available capital to fund future acquisitions. If we complete any future acquisitions, we may not be able to successfully integrate the 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 local regulations and market customs 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.



## Table of Contents

• 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. 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.

## • Our pension plans may require future pension contributions which could limit our flexibility in managing our company

The projected benefit obligation liability of our defined benefit pension plans of $869 million exceeded the fair value of the plan assets of $832 million by approximately $37 million at December 31, 2019. U.S. employees hired after January 1, 2010 have not participated in our defined benefit plan, and benefit accruals for the majority of current salaried and hourly employees ended on December 31, 2014. We forecast that we will not be required to make a contribution to the plan in 2020, and we do not plan to make any voluntary contributions. However, we cannot provide any assurance that contributions will not be required in the future. Among the key assumptions inherent in our actuarially calculated pension plan obligation and pension plan expense are the discount rate and the expected rate of return on plan assets. If interest rates and actual rates of return on invested plan assets were to decrease significantly, our pension plan obligations could increase materially. The size of future required pension contributions could result in us dedicating a significant portion of our cash flows from operations to making contributions which could negatively impact our flexibility in managing our company.

• 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, 2019, through the voting trust, these members of the Smith Family own approximately 63.7 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 96.5 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.

## ITEM 1B - UNRESOLVED STAFF COMMENTS

None.

## ITEM 2 - PROPERTIES

Properties utilized by us at December 31, 2019 were as follows:

## North America

In this segment, we have 17 manufacturing plants located in nine states and two non-U.S. countries, of which 14 are owned directly by us or our subsidiaries and three are leased from outside parties. The terms of leases in effect at December 31, 2019 expire between 2020 and 2025.

## Rest of World

In this segment, we have six manufacturing plants located in four non-U.S. countries, of which four are owned directly by us or our subsidiaries and two are leased from outside parties. The terms of leases in effect at December 31, 2019 expire between 2020 and 2022.

## Corporate and General

We consider our plants and other physical properties to be suitable, adequate, and of sufficient productive capacity to meet the requirements of our business. The manufacturing plants operate at varying levels of utilization depending on the type of operation and market conditions. The executive offices of the company, which are leased, are located in Milwaukee, Wisconsin.

## ITEM 3 - LEGAL PROCEEDINGS

We are involved in various unresolved legal actions, administrative proceedings and claims in the ordinary course of our business involving product liability, property damage, insurance coverage, exposure to asbestos and other substances, patents and environmental matters, including the disposal of hazardous waste. Although it is not possible to predict with certainty the outcome of these unresolved legal actions or the range of possible loss or recovery, we believe, based on past experience, adequate reserves and insurance availability, that these unresolved legal actions will not have a material effect on our financial position or results of operations. A more detailed discussion of certain of these matters appears in Note 16 of Notes to Consolidated Financial Statements.

On May 28, 2019, a putative securities class action lawsuit was filed in the U.S. District Court for the Eastern District of Wisconsin against the Company and certain of its current or former officers. Subsequently, on November 22, 2019, a consolidated amended complaint was filed by the lead plaintiff. This action, now captioned as City of Birmingham Retirement and Relief System v. A. O. Smith Corporation, et al., asserts securities fraud claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 ("Exchange Act"), and seeks damages and other relief based upon the allegations in the complaint. On January 24, 2020, A. O. Smith and the other defendants moved to dismiss the consolidated amended complaint for failure to state a claim. Their motion is currently pending. A shareholder derivative lawsuit, captioned as Pierce v. A. O. Smith Corporation, et al. and based on similar allegations as the putative class action, was filed on August 20, 2019, also in the U.S. District Court for the Eastern District of Wisconsin. On November 6, 2019, the plaintiff in the derivative action moved to dismiss his lawsuit, and re-filed it in the U.S. District Court for the District of Delaware on November 12, 2019. The derivative action asserts claims under Sections 14(a) and 20(a) of the Exchange Act, as well as for breach of fiduciary duty, unjust enrichment, and waste of corporate assets, and seeks damages and other relief based upon the allegations in the complaint. On February 12, 2020, the parties filed a stipulation seeking to stay the derivative lawsuit pending resolution of the City of Birmingham lawsuit. On February 13, 2020, a second shareholder derivative suit, captioned as Jarozewski v. A. O. Smith Corporation, et al., was filed in the U.S. District Court for the District of Delaware, asserting claims under Sections 10(b), 14(a) and 20(a) of the Exchange Act, as well as for breach of fiduciary duty, unjust enrichment, and insider trading, and seeks damages and other relief based upon the allegations in the complaint. On February 19, 2020, the U.S. District Court for the District of Delaware entered the stipulation staying the Pierce lawsuit. Consequently, the Company anticipates that the Jarozewski lawsuit will be stayed as well.

## ITEM 4 - MINE SAFETY DISCLOSURES

## 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, 2020, the approximate number of stockholders of record of Common Stock and Class A Common Stock were 592 and 160, 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 18 of Notes to Consolidated Financial Statements appearing elsewhere herein.

(d) Stock Repurchases. In the second quarter of 2019, our Board of Directors approved adding three million shares of Common Stock to an existing discretionary share repurchase authority. Under the share repurchase program, we may purchase our Common Stock 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 2019, we repurchased 6,113,038 shares at an average price of $47.06 per share and at a total cost of $287.7 million. As of December 31, 2019, there were 2,962,215 shares remaining on the existing repurchase authorization.

The following table sets forth the number of shares of common stock we repurchased during the fourth quarter of 2019:

## 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 and electric water heaters, boilers, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world. Our Rest of World segment also manufactures and markets in-home air purification products in China.

In our North America segment, we project our sales in the U.S. will grow approximately six percent in 2020 compared to 2019 due to higher water heater and boiler volumes resulting from expected industry-wide new construction growth and expansion of replacement demand. We continued to expand our North America water treatment platform in 2019 by acquiring Water-Right, Inc. and its affiliated entities (Water-Right) in April 2019. We expect sales of North America water treatment products to increase by 20 to 25 percent in 2020, compared to 2019, primarily due to volume growth and a full year of Water-Right sales.

In our Rest of World segment, we expect 2020 China sales to grow by approximately one percent in U.S. dollar terms and approximately 2.5 percent in local currency compared with 2019, as we believe the Chinese economy will continue to be weak. In addition, we expect our sales in India to grow between 15 and 20 percent in 2020 from approximately $39 million in 2019.

Combining all of these factors, we expect our consolidated sales to grow 4.5 to 5.5 percent in 2020. Our 2020 guidance introduced on January 28, 2020, excludes the potential impact to our businesses from the coronavirus originating in China. As of the date of this filing, while not yet quantifiable, we now expect the coronavirus will have a material adverse impact on our operating results in the first quarter of 2020 and we continue to assess the financial impact for the remainder of 2020.

Our stated acquisition strategy includes a number of our water-related strategic initiatives. We will seek to continue to grow our core residential and commercial water heating, boiler and water treatment businesses throughout the world. We will also continue to look for opportunities to add to our existing operations in high growth regions demonstrated by our introduction of water treatment products in India and Vietnam and air purification products as well as range hoods and cooktops in China.

## RESULTS OF OPERATIONS

Our sales in 2019 were $2,993 million, a decline of 6.1 percent compared to our 2018 sales of $3,188 million. The decrease in 2019 sales was primarily due to a 23 percent decline in China sales in U.S. dollar terms, which was largely a result of weaker end-market demand in the region, year over year channel inventory shifts, and a higher mix of sales of mid-price products versus premium price products than in the prior year. Excluding the unfavorable impact from currency translation, China sales declined 19 percent in 2019. The sales reduction in China more than offset the benefits of higher sales in North America, which were primarily a result of higher sales of water treatment products, including incremental sales from our acquisition, Water-Right, and water heater pricing actions related to steel and freight cost increases. The increase in North America sales was partially offset by lower residential water heater volumes. Our sales in 2018 were a company record $3,188 million surpassing 2017 sales of $2,997 million by 6.4 percent. The increase in sales in 2018 was primarily due to pricing actions related to higher steel costs and higher sales of boilers and residential water heaters in the U.S. as well as higher sales of water treatment products in China. Our global water treatment sales grew to approximately $400 million in 2018. Total sales in China grew four percent in 2018. Excluding the impact of the appreciation of the Chinese currency against the U.S. dollar, our sales in China increased almost two percent in 2018.

Our gross profit margin in 2019 of 39.5 percent declined compared to our gross profit margin of 41.0 percent in 2018 primarily due to the lower sales volumes in China and a higher mix of mid-price products, which have lower margins, in that region. Our gross profit margin in 2018 of 41.0 percent was essentially flat compared to our gross profit margin of 41.1 percent in 2017.

Selling, general and administrative (SG&A) expenses were $715.6 million in 2019 or $38.2 million lower than in 2018. The decrease in SG&A expenses in 2019 was primarily due to lower advertising and selling expenses in China. SG&A expenses were $31.0 million higher in 2018 than in 2017. The increase in SG&A expenses in 2018 to $753.8 million was primarily due to higher advertising expenses related to brand building and higher product development engineering expenses in China.

On March 21, 2018, we announced a plan to transfer water heater, boiler and storage tank production from our Renton, Washington plant to our other U.S. plants. The majority of the consolidation of operations occurred in the second quarter of 2018. As a result of the relocation of production, we incurred pre-tax restructuring and impairment expenses of $6.7 million in the first quarter of 2018, primarily related to employee severance and compensation-related costs, building lease exit costs and the impairment of assets. These activities are reflected in “restructuring and impairment expenses” in the accompanying financial statements.



## Table of Contents

We are providing non-U.S. Generally Accepted Accounting Principles (GAAP) measures (adjusted earnings, adjusted earnings per share, and adjusted segment earnings) that exclude restructuring and impairment expenses. Reconciliations to measures on a GAAP basis are provided later in this section. We believe that the measures of adjusted earnings, adjusted EPS, and adjusted segment earnings 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 we do not consider to be a component of our core operating performance.

Interest expense was $11.0 million in 2019 compared to $8.4 million in 2018 and $10.1 million in 2017. The increase in interest expense in 2019 was primarily due to higher debt levels to fund the acquisition of Water-Right and share repurchase activity. The decline in interest expense in 2018 compared to 2017 was a result of lower debt levels, primarily due to the repatriation of approximately $312 million of cash from outside of the U.S, which was primarily used to pay down floating rate debt, as well as to fund our share repurchase activity and dividend payments. This decline was partially offset by higher interest rates in 2018.

Other income was $18.0 million in 2019 compared to $21.2 million in 2018 and $21.3 million in 2017. The decrease in other income in 2019 compared to 2018 was primarily due to lower non-service cost related pension income and lower interest income.

Pension income in 2019 was $6.2 million compared to $8.7 million in 2018 and $9.1 million in 2017. 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 income are reflected in other income.

Our effective income tax rate was 21.6 percent in 2019, compared with 20.4 percent in 2018 and 43.1 percent in 2017. Our effective income tax rates in 2019 and 2018 were lower than our adjusted effective income tax rate in 2017 due to lower federal income taxes related to the U.S. Tax Cuts and Jobs Act of 2017 (U.S. Tax Reform). Our effective income tax rate in 2019 was higher than 2018 primarily due to a change in geographic earnings mix. The effective income tax rate in 2017 was significantly higher due to one-time charges associated with U.S. Tax Reform of $81.8 million, primarily related to the mandatory repatriation tax on undistributed foreign earnings that we are required to pay over eight years. Excluding the impact of the U.S. Tax Reform one-time charges, our adjusted effective income tax rate was 27.4 percent in 2017. We estimate our annual effective income tax rate for the full year 2020 will be approximately 21.5 to 22.0 percent.

## North America

Sales in our North America segment were $2,084 million in 2019 or $39 million higher than sales of $2,045 million in 2018. The increase in segment sales was primarily due to the incremental Water-Right sales of $44 million, water heater pricing actions related to steel and freight cost increases, and higher sales of water treatment products, which were partially offset by lower residential water heater volumes. Sales in our North America segment were $2,045 million in 2018 or $140 million higher than sales of $1,905 million in 2017. The increase in sales in 2018 compared to 2017 was primarily due to pricing actions related to higher steel costs and higher volumes of boilers and residential water heaters in the U.S. North America water treatment sales, including a full year of sales from Hague, which we purchased in 2017, and the launch of products at Lowe's commencing in August 2018, incrementally added approximately $29 million of sales in 2018.

North America segment earnings were $488.9 million in 2019 compared to segment earnings of $464.1 million and $428.6 million in 2018 and 2017, respectively. Segment margins were 23.5 percent, 22.7 percent and 22.5 percent in 2019, 2018 and 2017, respectively. Adjusted segment earnings and segment margin in 2018, which exclude restructuring and impairment expenses, were $470.8 million and 23.0 percent, respectively. The higher segment earnings and segment margin in 2019 compared to 2018 adjusted segment earnings and adjusted segment margin were primarily a result of pricing actions, lower steel costs, and higher sales of water treatment products, that included incremental volumes from our acquisition, Water-Right. These increases were partially offset by the unfavorable impact from lower residential water heater volumes. The higher adjusted segment earnings and adjusted segment margin in 2018 compared to 2017 were primarily due to the favorable impact from higher sales of residential water heaters and boilers and pricing actions in the U.S. that were partially offset by higher steel costs and one-time expenses associated with the launch of water treatment products at Lowe's. We estimate our 2020 North America segment margin will be between 23.25 and 24.25 percent.

## Rest of World

Sales in our Rest of World segment in 2019 were $936 million or $238 million lower than sales of $1,174 million in 2018. Lower sales in 2019 compared to 2018 was largely a result of decreased China sales which declined 23 percent in U.S. dollar terms and 19 percent in local currency terms. The decline in China sales was primarily due to weaker end-market demand, elevated channel inventory levels for the first three quarters of 2019 that returned to a more normal range of two to three months by the end of 2019, and a higher mix of mid-price products versus premium priced products. In addition, the weaker Chinese currency



## Table of Contents

unfavorably impacted translated sales by approximately $39 million. Sales in India grew approximately 13 percent in 2019 compared to 2018. Sales in China grew four percent in 2018 compared to 2017 primarily due to higher sales of water treatment products, including consumables, which were partially offset by lower sales of electric water heaters and air purifiers. The appreciation of the Chinese currency against the U.S. dollar contributed approximately $23 million to segment sales in 2018. Excluding the benefit of the Chinese currency appreciation, sales in China increased 1.9 percent in 2018. Water heater and water treatment sales in India increased $8 million, over 30 percent, in 2018 compared to 2017.

Rest of World segment earnings were $40.2 million in 2019 compared to segment earnings of $149.3 million in both 2018 and 2017. Segment margins were 4.3 percent in 2019 compared to 12.7 percent and 13.4 percent in 2018 and 2017, respectively. The decline in 2019 segment earnings and margin compared to 2018 was primarily due to lower sales in China and a higher mix of mid-price products, which have lower margins, that when combined, more than offset benefits to profits from lower SG&A expenses and material costs in that region. Currency translation reduced segment earnings by approximately $3.0 million in 2019 compared to 2018. Segment earnings in 2018 were flat compared to 2017 primarily due to higher water treatment product sales and improved performance in India that were offset by lower sales of electric water heaters and air purifiers in China as well as higher SG&A expenses. Higher SG&A expenses in China were primarily due to higher advertising expenses related to brand building and higher product development engineering expenses. Segment margin declined in 2018 compared to 2017 as a result of the factors above. We expect our 2020 Rest of World segment margin will be approximately five percent.

## LIQUIDITY AND CAPITAL RESOURCES

Our working capital was $733.9 million at December 31, 2019 compared with $853.2 million and $973.1 million at December 31, 2018 and December 31, 2017, respectively. Approximately $165 million in foreign cash, cash equivalents and marketable securities was repatriated in 2019 and utilized to repay floating rate debt, pay dividends and repurchase shares. The decline in cash, cash equivalents and marketable securities and sales-related decreases in accounts receivable partially offset by lower accounts payable balances explains the majority of the decline in working capital in 2019. Approximately $312 million in foreign cash was repatriated in 2018 and utilized to repay floating rate debt, pay dividends and repurchase shares. The decline in cash, cash equivalents and marketable securities balances more than offset sales-related increases in accounts receivable and explains the majority of the decline in working capital in 2018. As of December 31, 2019, essentially all of our $551.4 million of cash, cash equivalents and marketable securities was held by our foreign subsidiaries. We expect to repatriate approximately $150 million in the first half of 2020 and use the proceeds to repay floating rate debt.

Cash provided by operating activities during 2019 was $456.2 million compared with $448.9 million during 2018 and $326.4 million during 2017. The increase in cash flows in 2019 compared with 2018 was primarily due to lower outlays for working capital which offset lower earnings in 2019. The increase in cash flows in 2018 compared to 2017 was primarily due to higher earnings and lower outlays for working capital in 2018.

Our capital expenditures were $64.4 million in 2019, $85.2 million in 2018 and $94.2 million in 2017. We broke ground in 2016 on the construction of a new water treatment and air purification products manufacturing facility in Nanjing, China, to support the expected growth of these products in China. The facility became operational in May 2018. Included in 2018 capital expenditures were approximately $13 million related to capacity expansion in China. Included in 2017 capital expenditures were approximately $24 million related to capacity expansion in China. For 2020, we project approximately $80 million of capital expenditures and approximately $85 million of depreciation and amortization expense.

In December 2016, we completed a $500 million multi-currency five-year revolving credit facility with a group of nine banks. The facility has an accordion provision which allows it to be increased up to $700 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, 2019. The facility backs up commercial paper and credit line borrowings, and it expires on December 15, 2021. As a result of the long-term nature of this facility, the commercial paper and credit line borrowings as well as drawings under the facility are classified as long-term debt.

At December 31, 2019, we had available borrowing capacity of $336.0 million under this facility. We believe that our combination of cash, available borrowing capacity and operating cash flow will provide sufficient funds to finance our existing operations for the foreseeable future.

Our total debt increased to $284.0 million at December 31, 2019 compared with $221.4 million at December 31, 2018. We repatriated approximately $150 million cash and paid down debt, which was more than offset by the purchase of Water-Right and share repurchase activity exceeding cash generation in the U.S. As a result, our leverage, as measured by the ratio of total debt to total capitalization, was 14.6 percent at the end of 2019 compared with 11.4 percent at the end of 2018.



## Table of Contents

Our 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 2019. We forecast that we will not be required to make a contribution to the plan in 2020, and we do not plan to make any voluntary contributions in 2020. For further information on our pension plans, see Note 13 of Notes to Consolidated Financial Statements.

In 2019, we repurchased 6,113,038 shares at an average price of $47.06 per share and a total cost of $287.7 million. Our Board of Directors increased the number of shares we are authorized to repurchase by 3,000,000 shares at its June 2019 meeting. A total of 2,962,215 shares remained on the existing repurchase authorization at December 31, 2019. Depending on factors such as stock price, working capital requirements and alternative investment opportunities, such as acquisitions, we expect to spend approximately $200 million on share repurchase activity in 2020 using a combination of a 10b5-1 repurchase plan and opportunistic purchases.

We have paid dividends for 80 consecutive years with annual amounts increasing each of the last 28 years. We paid dividends of $0.90 per share in 2019 compared with $0.76 per share in 2018. We increased our dividend by nine percent in the fourth quarter of 2019, and the five-year compound annual growth rate of our dividend is approximately 25 percent.

## Aggregate Contractual Obligations

A summary of our contractual obligations as of December 31, 2019, is as follows:

<table><tr><td rowspan="2">(dollars in millions)</td><td colspan="6">Payments due by period</td></tr><tr><td>Total</td><td>Less Than 1 year</td><td>1 - 2 Years</td><td>3 - 5 Years</td><td>More than 5 years</td><td></td></tr><tr><td>Contractual Obligations</td><td></td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>Long-term debt</td><td>$284.0</td><td>$ 6.8</td><td>$177.6</td><td>$20.1</td><td>$ 79.5</td><td></td></tr><tr><td>Fixed rate interest</td><td>26.0</td><td>3.7</td><td>6.8</td><td>5.7</td><td>9.8</td><td></td></tr><tr><td>Operating leases</td><td>64.9</td><td>14.0</td><td>19.5</td><td>8.6</td><td>22.8</td><td></td></tr><tr><td>Purchase obligations</td><td>145.9</td><td>145.8</td><td>0.1</td><td>—</td><td>—</td><td></td></tr><tr><td>Pension and post-retirement obligations</td><td>49.3</td><td>9.8</td><td>2.2</td><td>2.0</td><td>35.3</td><td></td></tr><tr><td>Total</td><td>$570.1</td><td>$ 180.1</td><td>$206.2</td><td>$36.4</td><td>$ 147.4</td><td></td></tr></table>

As of December 31, 2019, our liability for uncertain income tax positions was $9.7 million. Due to the high degree of uncertainty regarding timing of potential future cash flows associated with these liabilities, we are unable to make a reasonably reliable estimate of the amount and period in which these liabilities might be paid.

We utilize blanket purchase orders to communicate expected annual requirements to many of our suppliers. Requirements under blanket purchase orders generally do not become committed until several weeks prior to our scheduled unit production. The purchase obligation amount presented above represents the value of commitments that we consider firm.

## Recent Accounting Pronouncements

## Critical Accounting Policies

Our accounting policies are described in Note 1 of Notes to 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 activity, 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.



## Table of Contents

## Goodwill and Indefinite-lived Intangible Assets

In conformity with U.S. Generally Accepted Accounting Principles (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 thorough and competent annual valuations of goodwill and indefinite-lived intangible assets and that there has been no impairment in goodwill or indefinite-lived assets in 2019.

## Product warranty

Our products carry warranties that generally range from one to ten 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, 2019 and 2018, our reserve for product warranties was $134.3 million and $139.4 million, respectively.

## Product liability

Due to the nature of our products, we are subject to product liability claims in the normal course of business. We maintain insurance to reduce our risk. Most insurance coverage includes self-insured retentions that vary by year. In 2019, we maintained a self-insured retention of $7.5 million per occurrence with an aggregate insurance limit of $125.0 million.

We establish product liability reserves for our self-insured retention portion of any known outstanding matters based on the likelihood of loss and our ability to reasonably estimate such loss. There is inherent uncertainty as to the eventual resolution of unsettled matters due to the unpredictable nature of litigation. We make estimates based on available information and our best judgment after consultation with appropriate advisors and experts. We periodically revise estimates based upon changes to facts or circumstances. We also utilize an actuary to calculate reserves required for estimated incurred but not reported claims as well as to estimate the effect of adverse development of claims over time. At December 31, 2019 and 2018, our reserve for product liability was $33.1 million and $39.3 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. Our assumption for the expected return on plan assets was 7.15 percent in 2019 and 2018. The discount rate used to determine net periodic pension costs increased to 4.32 percent in 2019 from 3.65 percent in 2018. For 2020, our expected return on plan assets is 6.75 percent and our discount rate is 3.18 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 equity managers is approximately 30 to 60 percent, with the remainder allocated primarily to bond managers, private equity managers and real estate managers. Our actual asset allocation as of December 31, 2019, was 42 percent to equity managers, 47 percent to bond managers, 10 percent to real estate managers, and one percent to private equity managers. 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 9.2 percent and 9.3 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 6.75 percent expected return on plan assets for 2020 is reasonable.



## Table of Contents

The discount rate assumptions used to determine future pension obligations at December 31, 2019 and 2018 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.

We recognized pension income of $6.2 million, $8.7 million, and $9.1 million in 2019, 2018, and 2017, respectively.

Costs associated with our replacement retirement plan in 2019 were approximately $6 million, consistent with 2018. We made changes to our pension plan including closing the plan to new entrants effective January 1, 2010, and the sunset of our plan for the majority of our employees on December 31, 2014. Lowering the expected return on plan assets by 25 basis points would decrease our net pension income for 2019 by approximately $1.9 million. Lowering the discount rate by 25 basis points would increase our 2019 net pension income by approximately $0.4 million.

In 2019, as part of our strategy to de-risk our defined benefit pension plan, the qualified defined benefit pension plan purchased a group annuity contract whereby an unrelated insurance company assumed a $31 million obligation to pay and administer future annuity payments for certain retirees and beneficiaries.

## Non-GAAP Measures

We provide non-GAAP measures (adjusted earnings, adjusted earnings per share (EPS) and adjusted segment earnings) that exclude restructuring and impairment expenses in 2018 and the impact of a one-time charge associated with U.S. Tax Reform in 2017.

We believe that the measures of adjusted earnings, adjusted EPS, and adjusted segment earnings 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 we do not consider to be a component of our core operating performance.

(1) We recognized $6.7 million of restructuring and impairment expenses in connection with the move of manufacturing operations from our Renton, Washington facility to other U.S. facilities. For additional information, see Note 5 of Notes to Consolidated Financial Statements.

(2) Excluding the impact of one-time U.S. Tax Reform charges, our 2017 adjusted effective income tax rate was 27.4 percent as compared to our effective income tax rate of 43.1 percent in 2017. For additional information, see Note 15 of Notes to Consolidated Financial Statements.

## Outlook

We expect higher boiler, water heater, and water treatment sales in North America in 2020 and project segment sales to grow by approximately six percent compared to 2019. Although China channel inventory levels have normalized to the range of two to three months, we believe the Chinese economy will remain weak in 2020 and expect that 2020 sales in China will increase by one percent in U.S. dollar terms and 2.5 percent in local currency terms. As a result, we expect our consolidated sales to grow between 4.5 to 5.5 percent in 2020. We plan to achieve full-year earnings of between $2.40 and $2.50 per share, which excludes the potential impacts from future acquisitions. Our 2020 guidance above which was introduced on January 28, 2020, excludes the potential impact on our businesses from the coronavirus originating in China. As of the date of this filing, while not yet quantifiable, we now expect the effects of the coronavirus to have a material adverse impact on our operating results in the first quarter of 2020 and we continue to assess the financial impact for the remainder of the year.

## 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 2019 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.

## 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 for periods of less than one year. We do not engage in speculation in our derivatives strategies. Further discussion regarding derivative instruments is contained in Note 1 of Notes to Consolidated Financial Statements.

We enter into foreign currency forward contracts to minimize the effect of fluctuating foreign currencies. At December 31, 2019, we had net foreign currency contracts outstanding with notional values of $205.6 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 $20.6 million. However, gains and losses from our forward contracts will be offset by gains and losses in the underlying transactions being hedged.

Our earnings exposure related to movements in interest rates is primarily derived from outstanding floating-rate debt instruments that are determined by short-term money market rates. At December 31, 2019, we had $164.0 million in outstanding floating-rate debt with a weighted-average interest rate of 2.5 percent at year end. A hypothetical ten percent annual increase or decrease in the year-end average cost of our outstanding floating-rate debt would result in a change in annual pre-tax interest expense of approximately $0.4 million.

## Forward-Looking Statements

This filing contains statements that the Company believes are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally can be identified by the use of words such as “may,” “will,” “expect,” “intend,” “estimate,” “anticipate,” “believe,” “forecast,” “continue,” “guidance” or words of similar meaning.

## REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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, 2019 and 2018, 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, 2019, 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, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, 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, 2019, 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 24, 2020 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 include 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 Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

## Product Warranty Liability Valuation

Description of the
Matter
At December 31, 2019, the Company’s product warranty liability was $134.3 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 ten 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 of the claims data against the Company’s claim log. 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. We also analyzed subsequent 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.

Accounting for Acquisitions – Valuation of Water-Right, Inc. Intangible Assets

During 2019, the Company completed its acquisition of Water-Right, Inc. for consideration of $107.0 million, net of cash acquired, as discussed in Note 3 to the consolidated financial statements. The transaction was accounted for using the purchase method of accounting.

Auditing the Company’s accounting for its acquisition of Water-Right, Inc. was complex due to the significant estimation uncertainty in the Company’s determination of the fair value of identified intangible assets of $60.4 million, which principally consisted of customer relationships and trademarks. The significant estimation uncertainty was primarily due to the sensitivity of the respective fair values to underlying assumptions about the future performance of the acquired business. The significant assumptions used to estimate the value of the intangible assets included discount rates and certain assumptions that form the basis of the forecasted results (including revenue growth rates, attrition rates and royalty rates). These significant assumptions are forward looking and could be affected by future economic and market conditions.

We obtained an understanding, evaluated the design, and tested the operating effectiveness of the Company’s controls over its accounting for acquisitions. For example, we tested controls over the estimation process supporting the measurement of customer relationships and trademark intangible assets, including management’s review of the significant assumptions used in the valuation models.

To test the estimated fair value of the customer relationship and trademark intangible assets, our audit procedures included, among others, evaluating the Company’s valuation methodology, and testing the significant assumptions discussed above including the completeness and accuracy of the underlying data supporting the significant assumptions and estimates. We compared the revenue growth rates to third-party industry projections for the water treatment and purification market and to the historical performance of the acquired business. We involved our valuation specialists to assist with our evaluation of the methodology used by the Company and significant assumptions included in the fair value estimates. For example, we evaluated the discount rates by comparing them to discount rate ranges that were independently developed using publicly available market data for comparable peers. We also compared the customer attrition rates to historical customer retention rates and the royalty rate to relevant comparable licensing agreements.

# 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. The Rest of World segment also manufactures and markets in-home air purification products in China.

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, 2019 and 2018, due to the short maturities or frequent rate resets of these instruments. The fair value of term notes with insurance companies was approximately $122.1 million as of December 31, 2019 compared with the carrying amount of $120.0 million for the same date. The fair value of term notes with insurance companies was approximately $120.0 million as of December 31, 2018 which approximated the carrying value.

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 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 2019, 2018, or 2017.

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, 2019, 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.

Inventory valuation. Inventories are carried at lower of cost and 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 61 percent and 64 percent of the Company’s total inventory at December 31, 2019 and 2018, 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.



## Table of Contents

## 1. Organization and Significant Accounting Policies (continued)

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 necessarily involve significant judgment.

Product warranties. The Company’s products carry warranties that generally range from one to ten 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 2019 and 2018:

<table><tr><td>Years ended December 31 (dollars in millions)</td><td>2019</td><td>2018</td></tr><tr><td>Balance at beginning of year</td><td>$139.4</td><td>$141.2</td></tr><tr><td>Expense</td><td>44.3</td><td>40.7</td></tr><tr><td>Claims settled</td><td>(49.4)</td><td>(42.5)</td></tr><tr><td>Balance at end of year</td><td>$134.3</td><td>$139.4</td></tr></table>

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” of the notes to consolidated financial statements 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 measured at fair value on a recurring basis are as follows (dollars in millions):

<table><tr><td>Fair Value Measurement Using</td><td>December 31, 2019</td><td>December 31, 2018</td></tr><tr><td>Quoted prices in active markets for identical assets (Level 1)</td><td>$ 177.4</td><td>$ 385.3</td></tr><tr><td>Significant other observable inputs (Level 2)</td><td>6.9</td><td>7.5</td></tr></table>

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 amounted to $110.7 million, $132.1 million and $126.9 million during 2019, 2018 and 2017, respectively. Included in total advertising costs are expenses associated with store displays for water heater, water treatment and air purification products in China that are amortized over 12 to 36 months which totaled $28.5 million, $38.7 million and $43.0 million during 2019, 2018 and 2017, respectively.

Research and development. Research and development costs are charged to operations as incurred and amounted to $87.9 million, $94.0 million and $86.4 million during 2019, 2018 and 2017, 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 $2.3 million, $2.4 million, and $11.6 million of discrete income tax benefits on settled stock based compensation awards during 2019, 2018, and 2017 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:

<table><tr><td></td><td>2019</td><td>2018</td><td>2017</td></tr><tr><td>Denominator for basic earnings per share - weighted-average shares outstanding</td><td>165,450,441</td><td>170,589,345</td><td>172,666,056</td></tr><tr><td>Effect of dilutive stock options, restricted stock and share units</td><td>1,260,456</td><td>1,604,695</td><td>1,939,133</td></tr><tr><td>Denominator for diluted earnings per share</td><td>166,710,897</td><td>172,194,040</td><td>174,605,189</td></tr></table>

In December 2019, the Financial Accounting Standards Board (FASB) amended Accounting Standards Codification (ASC) 740, Income Taxes (issued under Accounting Standards Update (ASU) 2019-12, "Simplifying the Accounting for Income Taxes"). This amendment removes certain exceptions to the general principles of ASC 740, and clarifies and amends existing guidance to improve consistent application. The amendment requires adoption on January 1, 2021, with early adoption permitted. The Company is currently evaluating the impact ASU 2019-12 will have on its consolidated financial statements.

In January 2017, the FASB amended ASC 350, Intangibles – Goodwill and Other (issued under ASU 2017-04, “Simplifying the Test for Goodwill Impairment”). This amendment simplifies the test for goodwill impairment by only requiring an entity to perform an annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount that the carrying amount exceeds the reporting unit’s fair value. Any loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendment requires adoption on January 1, 2020. The Company does not expect that the adoption of ASU 2017-04 will have a material impact on its consolidated balance sheets, statements of earnings or statements of cash flows.

In June 2016, the FASB issued ASC 326, Financial Instruments – Credit Losses (issued under ASU 2016-13) which modifies the measurement of expected credit losses on certain financial instruments. ASU 2016-13 requires adoption on January 1, 2020. The adoption of ASU 2016-13 will not have a material impact on its consolidated balance sheets, statements of earnings or statements of cash flows.

In February 2016, the FASB amended ASC 842, Leases (issued under ASU 2016-02). This amendment requires the recognition of lease assets and lease liabilities on the balance sheet for most leasing arrangements classified as operating leases. The Company applied the modified retrospective transition method and elected the transition option to use the effective date of January 1, 2019, as the date of the initial application. The Company elected the package of practical expedients as well as a separate practical expedient not to separate lease and non-lease components. The Company did not elect the hindsight practical expedient. The adoption of ASU 2016-02 did not have a material impact on the Company’s consolidated balance sheets, statements of earnings or statements of cash flows. Refer to Note 4, Leases, for additional information.

## 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 transaction price. The Company’s payment terms for the majority of its customers are 30 to 90 days from shipment.

Additionally, certain customers in China pay the Company prior to the shipment of products resulting in a customer deposits liability of $49.6 million and $47.0 million at December 31, 2019 and December 31, 2018, respectively. The Company assesses 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. The Company’s allowance for doubtful accounts was $6.7 million and $6.4 million at December 31, 2019 and December 31, 2018, respectively.

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 and electric water heaters, boilers, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world. The Rest of World segment also manufactures and markets in-home air purification products in China.

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 channel 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.

The North America segment major product lines are defined as the following:

Water heaters The Company’s water heaters are open water heating systems that heat potable water. Typical applications for water heaters include residences, restaurants, hotels and motels, office buildings, laundries, car washes and small businesses. The Company sells residential and commercial water heater products and related parts through its wholesale distribution channel, which includes more than 1,300 independent wholesale plumbing distributors. The Company also sells residential water heaters and related parts through retail and maintenance, repair and operations (MRO) channels. A significant portion of the Company’s water heater sales in the North America segment is derived from the replacement of existing products.

Boilers The Company’s boilers are closed loop water heating systems used primarily for space heating or hydronic heating. The Company’s 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. The Company’s boiler distribution channel is comprised primarily of manufacturer representative firms, with the remainder of our boilers distributed through wholesale channels. The Company’s boiler sales in the North America segment are derived from a combination of replacement of existing products and new construction.

Water treatment products The Company’s 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. Typical applications for the Company’s water treatment products include residences, restaurants, hotels and offices. The Company sells water treatment products through its wholesale and retail distribution channels, similar to water heater products and related parts. The Company’s water treatment products are also sold through independent water quality dealers as well as directly to consumers including through internet sales channels. A portion of the Company’s sales of water treatment products in the North America segment is comprised of replacement filters.

The following table disaggregates the Company’s net sales by segment. As described above, the Company’s North America segment sales are further disaggregated by major product line. In addition, the Company’s Rest of World segment sales are disaggregated by China and all other Rest of World.

## 3. Acquisitions

On April 8, 2019, the Company acquired 100 percent of the shares of Water-Right, Inc. and its affiliated entities (Water-Right), a Wisconsin-based water treatment company. With the addition of Water-Right, the Company grew its North America water treatment platform. Water-Right is included in the Company’s North America segment for reporting purposes.

The Company paid an aggregate cash purchase price of $107.0 million, net of cash acquired. In addition, the Company established a $4.0 million escrow to satisfy any potential obligations of the former owners of Water-Right, should they arise.

The following table summarizes the preliminary estimate of the fair value of the assets acquired and liabilities assumed at the date of acquisition of Water-Right for purposes of allocating the purchase price. The Company is in the process of finalizing the fair value estimates; therefore, the allocation of the purchase price is subject to refinement. Significant assumptions used to estimate the fair value of intangible assets acquired include discount rates and certain assumptions that form the basis of the forecasted results, including revenue growth rates, attrition rates and royalty rates. The preliminary $60.4 million of acquired identifiable intangible assets was comprised of the following: $40.2 million of customer relationships being amortized over 20 years, $19.0 million of trademarks not subject to amortization, and $1.2 million of non-compete agreements being amortized over 7.5 years.

As required under ASC 805 Business Combinations, Water-Right’s results of operations have been included in the Company’s consolidated financial statements from April 8, 2019, the date of acquisition. Revenues and pre-tax earnings associated with Water-Right included in the consolidated statement of earnings for the year ended December 31, 2019 totaled $44.3 million and $7.1 million, respectively, which included $7.5 million of operating earnings less $0.4 million of acquisition-related costs incurred by the Company resulting from the acquisition.

## 3. Acquisitions (continued)

On September 5, 2017, the Company acquired 100 percent of the shares of Hague, an Ohio-based water softener company. With the addition of Hague, the Company grew its North America water treatment platform. Hague is included in the Company’s North America segment for reporting purposes.

The Company paid an aggregate cash purchase price of $43.1 million, net of $4.1 million of cash acquired. In addition, the Company established a $1.5 million holdback liability to satisfy any potential obligations of the former owners of Hague, should they arise. The Company also agreed to make a contingent payment of up to an additional $2.0 million based on the amount by which products manufactured by or branded Hague increase over the two-year period ending June 30, 2019. In addition, the Company incurred acquisition-related costs of approximately $0.2 million.

As of the acquisition date, the Company estimated the fair value of the holdback liability and additional contingent consideration at $1.5 million and $2.0 million, respectively. During 2018, the Company finalized the amount of acquisition date working capital, which resulted in a $1.3 million payment to the former owners of Hague related to the aforementioned holdback. The Company also paid $2.0 million of contingent payments associated with the amount by which sales of products manufactured by Hague increase over the two-year period ending June 30, 2019.

The following table summarizes the allocation of fair value of the assets acquired and liabilities assumed at the date of acquisition of Hague for purposes of allocating the purchase price. Significant assumptions used to estimate the fair value of intangible assets acquired include discount rates and certain assumptions that form the basis of the forecasted results, including revenue growth rates, attrition rates and royalty rates. The $12.8 million of acquired intangible assets was comprised of $1.1 million of trade names that are not subject to amortization and $11.7 million of customer lists being amortized over 18 years.

## 4. Leases

The Company’s lease portfolio consists of operating leases for buildings and equipment, such as forklifts and copiers, primarily in the United States and China. The Company defines a lease as a contract that gives the Company the right to control the use of a physical asset for a stated term. The Company pays the lessor for that right, with a series of payments defined in the contract and a corresponding right of use operating lease asset and liability are recorded. The Company has elected not to record leases with an initial term of 12 months or less on its condensed consolidated balance sheet. To determine balance sheet amounts, required legal payments are discounted using the Company’s incremental borrowing rate. The incremental borrowing rate is the rate of interest that the Company would incur if it were to borrow, on a collateralized basis, an amount equal to the value of the leased item over a similar term, in a similar economic environment. Variable lease components not based on an index or rate are excluded from the measurement of the lease asset and liability and expensed as incurred for all asset classes.

Certain leases include one or more options to renew or terminate. Renewal terms can extend the lease term from one to five years and options to terminate can be effective within one year. The exercise of lease renewal or termination is at the Company’s discretion and when it is determined to be reasonably certain to renew or terminate, the option is reflected in the measurement of lease asset and liability. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants or material subleases. Cash flows associated with leases are materially consistent with the expense recorded in the condensed consolidated statement of earnings.

## 12. Stock Based Compensation

The Company adopted the A. O. Smith Combined Incentive Compensation Plan (the “Plan”) effective January 1, 2007. The Plan was reapproved by stockholders on April 16, 2012. The Plan is a continuation of the A. O. Smith Combined Executive Incentive Compensation Plan which was originally approved by stockholders in 2002. The number of shares available for granting of options or share units at December 31, 2019, was 1,855,560. Upon stock option exercise or share unit vesting, shares are issued from treasury stock.

Total stock based compensation expense recognized in 2019, 2018 and 2017 was $13.3 million, $10.1 million and $9.9 million, respectively.

## Stock Options

The stock options granted in 2019, 2018 and 2017 have three year pro rata vesting from the date of grant. Stock options are issued at exercise prices equal to the fair value of the Company’s Common Stock on the date of grant. For active employees, all options granted in 2019, 2018 and 2017 expire ten years after the date of grant. The Company’s stock options are expensed ratably over the three year vesting period. Included in stock option expense for 2019, 2018 and 2017 was $6.4 million, $4.4 million and $4.7 million, respectively. Included in the stock option expense recognized in 2019, 2018 and 2017 is expense associated with the accelerated vesting of stock option awards for certain employees who either are retirement eligible or become retirement eligible during the vesting period.

Changes in options, all of which relate to the Company’s Common Stock, were as follows:

<table><tr><td rowspan="2">Years Ended December 31</td><td colspan="3">2019</td><td colspan="3">2018</td><td colspan="3">2017</td></tr><tr><td>Number of Options</td><td>Weighted Average Exercise Price</td><td>Number of Options</td><td>Weighted Average Exercise Price</td><td>Number of Options</td><td>WeightED Average Exercise Price</td><td>Number of Options</td><td>Weighted Average Exercise Price</td><td>Number of Exercise Price</td></tr><tr><td>Number of shares under options:</td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>Outstanding at beginning of year</td><td>2,432,689</td><td>33.05</td><td>2,263,126</td><td>27.73</td><td>2,664,333</td><td>21.69</td><td></td><td></td><td></td></tr><tr><td>Granted</td><td>557,045</td><td>49.49</td><td>373,220</td><td>61.62</td><td>358,150</td><td>50.16</td><td></td><td></td><td></td></tr><tr><td>Exercised \( ^{(1)} \)</td><td>(249,840)</td><td>18.55</td><td>(176,302)</td><td>22.93</td><td>(752,603)</td><td>16.93</td><td></td><td></td><td></td></tr><tr><td>Forfeited</td><td>(11,544)</td><td>54.02</td><td>(27,355)</td><td>47.95</td><td>(6,754)</td><td>37.46</td><td></td><td></td><td></td></tr><tr><td>Outstanding at end of year \( ^{(2)} \)</td><td>2,728,350</td><td>37.64</td><td>2,432,689</td><td>33.05</td><td>2,263,126</td><td>27.73</td><td></td><td></td><td></td></tr><tr><td>Exercisable at end of year \( ^{(3)} \)</td><td>1,820,743</td><td>30.07</td><td>1,665,184</td><td>24.52</td><td>1,387,259</td><td>20.48</td><td></td><td></td><td></td></tr></table>

(1) The total intrinsic value of options exercised in 2019, 2018 and 2017 was $7.7 million, $6.8 million and $29.1 million, respectively.

(2) The weighted average remaining contractual life of options outstanding was 7 years at December 31, 2019, December 31, 2018, and December 31, 2017. The aggregate intrinsic value of options outstanding at December 31, 2019 was $34.2 million.

(3) The weighted average remaining contractual life of options exercisable was 6 years at December 31, 2019, December 31, 2018 and, December 31, 2017. The aggregate intrinsic value of options exercisable at December 31, 2019 was $34.2 million.

<table><tr><td></td><td>Number of Options</td><td>Weighted Avg. Per Share Exercise Price</td></tr><tr><td>Nonvested options at beginning of year</td><td>767,505</td><td>51.55</td></tr><tr><td>Granted</td><td>557,045</td><td>49.49</td></tr><tr><td>Vested</td><td>(408,648)</td><td>45.87</td></tr><tr><td>Forfeited</td><td>(8,295)</td><td>53.88</td></tr><tr><td>Nonvested options at end of year</td><td>907,607</td><td>52.82</td></tr></table>



## Table of Contents

## 12. Stock Based Compensation (continued)

The weighted-average fair value per option at the date of grant during 2019, 2018 and 2017, using the Black-Scholes option-pricing model, was $10.83, $14.80 and $13.04, respectively. Assumptions were as follows:

<table><tr><td></td><td>2019</td><td>2018</td><td>2017</td></tr><tr><td>Expected life (years)</td><td>5.5</td><td>5.7</td><td>5.7</td></tr><tr><td>Risk-free interest rate</td><td>2.7%</td><td>2.9%</td><td>2.4%</td></tr><tr><td>Dividend yield</td><td>1.6%</td><td>1.0%</td><td>1.0%</td></tr><tr><td>Expected volatility</td><td>22.8%</td><td>22.1%</td><td>26.5%</td></tr></table>

The expected lives of options for purposes of these models are based on historical exercise behavior. The risk free interest rates for purposes of these models are based on the U.S. Treasury yield curve in effect on the date of grant for the respective expected lives of the option. The expected dividend yields for purposes of these models are based on the dividends paid in the preceding four quarters divided by the grant date market value of the Common Stock. The expected volatility for purposes of these models are based on the historical volatility of the Common Stock.

## Stock Appreciations Rights (SARs)

In 2015, certain non-U.S.-based employees were granted SARs. Each SAR award granted the employee the right to receive cash equal to the excess of the share price of the Company’s Common Stock on the date that a participant exercises such right over the grant date value of the SAR. SARs granted had three-year pro rata vesting from the date of grant. SARs were issued at exercise prices equal to the fair value of the Company’s Common Stock on the date of grant and expire ten years from the date of grant. The fair value and compensation expense related to SARs are measured at each reporting period using the Black-Scholes option-pricing model, using assumptions similar to stock option awards. No SARs were granted in 2019, 2018 or 2017. As of December 31, 2019, there were 14,880 SARs outstanding and exercisable. In 2018, there were 16,170 SARs outstanding and exercisable. In 2017, there were 23,660 SARs outstanding and 15,774 were exercisable. Stock based compensation expense attributable to SARs was minimal in 2019, 2018 and 2017.

## Restricted Stock and Share Units

Participants may also be awarded shares of restricted stock or share units under the Plan. Share units vest three years after the date of grant. The Company granted 140,102, 106,581 and 107,853 share units under the plan in 2019, 2018 and 2017, respectively.

The share units were valued at $6.9 million, $6.6 million and $5.4 million at the date of issuance in 2019, 2018 and 2017, respectively, based on the price of the Company’s Common Stock at the date of grant. The shares units are recognized as compensation expense ratably over the three-year vesting period; however, included in share unit expense was expense associated with the accelerated vesting of share unit awards for certain employees who are retirement eligible or will become retirement eligible during the vesting period. Stock based compensation expense of $6.9 million, $5.7 million and $5.2 million was recognized in 2019, 2018 and 2017, respectively. Certain non-U.S.-based employees receive the cash value of the share price at the vesting date in lieu of shares. Unvested cash-settled awards are remeasured at each reporting period.

A summary of share unit activity under the plan is as follows:

<table><tr><td></td><td>Number of Units</td><td>Weighted-Average Grant Date Value</td></tr><tr><td>Issued and unvested at January 1, 2019</td><td>379,601</td><td>$ 42.93</td></tr><tr><td>Granted</td><td>140,102</td><td>49.44</td></tr><tr><td>Vested</td><td>(147,642)</td><td>31.35</td></tr><tr><td>Forfeited</td><td>(5,959)</td><td>55.48</td></tr><tr><td>Issued and unvested at December 31, 2019</td><td>366,102</td><td>49.92</td></tr></table>

## 13. Pension and Other Post-retirement Benefits

The Company provides retirement benefits for all U.S. employees including benefits for employees of previously owned businesses which were earned up to the date of sale. The Company also has two foreign pension plans, neither of which is material to the Company’s financial position.

The Company has a defined contribution plan which matches 100 percent of the first one percent of contributions made by participating employees and matches 50 percent of the next five percent of employee contributions. The Company also has defined contribution plans for certain hourly employees which provide for matching Company contributions.

The Company also has a defined benefit plan for salaried employees and its non-union hourly workforce. In 2009, the Company announced U.S. employees hired after January 1, 2010, would not participate in the defined benefit plan, and benefit accruals for the majority of current salaried and hourly employees sunset on December 31, 2014. An additional Company contribution is made to the defined contribution plan in lieu of benefits earned in a defined benefit plan. The Company also has defined benefit and contribution plans for certain union hourly employees.

The Company has unfunded defined-benefit post-retirement plans covering certain hourly and salaried employees that provide medical and life insurance benefits from retirement to age 65. Certain hourly employees retiring after January 1, 1996, are subject to a maximum annual benefit and salaried employees hired after December 31, 1993, are not eligible for post-retirement medical benefits.

The estimated net actuarial loss and prior service cost for the pension plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2020 are $19.8 million and $0.5 million, respectively. The estimated net actuarial loss and prior year service cost for the post-retirement benefit plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2020 are $ - million and $0.3 million, respectively. As permitted under ASC 715, the amortization of any prior service cost was previously determined using a straight-line amortization of the cost over the average remaining service period of employees expected to receive benefits under the plan.

The 2019 and 2018 after tax adjustments for additional minimum pension liability resulted in other comprehensive gain (loss) of $2.9 million and ($13.1) million, respectively.

Actuarial assumptions used to determine benefit obligations at December 31 are as follows:

<table><tr><td rowspan="2"></td><td colspan="2">Pension Benefits</td><td colspan="2">Post-retirement Benefits</td></tr><tr><td>2019</td><td>2018</td><td>2019</td><td>2018</td></tr><tr><td>Discount rate</td><td>3.18%</td><td>4.32%</td><td>3.40%</td><td>4.46%</td></tr></table>

Actuarial assumptions used to determine net periodic benefit cost for the year ended December 31 are as follows:

<table><tr><td rowspan="2">Years ended December 31</td><td colspan="3">Pension Benefits</td><td colspan="3">Post-retirement Benefits</td></tr><tr><td>2019</td><td>2018</td><td>2017</td><td>2019</td><td>2018</td><td>2017</td></tr><tr><td>Discount rate</td><td>4.32%</td><td>3.65%</td><td>4.15%</td><td>4.45%</td><td>3.79%</td><td>4.40%</td></tr><tr><td>Expected long-term return on plan assets</td><td>7.15%</td><td>7.15%</td><td>7.50%</td><td>n/a</td><td>n/a</td><td>n/a</td></tr><tr><td>Rate of compensation increase</td><td>4.00%</td><td>4.00%</td><td>4.00%</td><td>4.00%</td><td>0.00%</td><td>4.00%</td></tr></table>

## Assumptions

In developing the expected long-term rate of return on plan assets assumption, the Company evaluated its pension plan’s target and actual asset allocation and expected long-term rates of return of equity and bond indices. The Company also considered its pension plan’s historical ten-year and 25-year compounded annualized returns of 9.2 percent and 9.3 percent, respectively.

The short-term investments included in the Company’s plan assets consist of cash and cash equivalents. The fair value of the remaining categories of the Company’s plan assets are valued as follows: equity securities are valued using the closing stock price on a national securities exchange, which reflects the last reported sales price on the last business day of the year; fixed income securities are valued using institutional bond quotes, which are based on various market and industry inputs; mutual funds and real estate funds are valued using the net asset value of the fund, which is based on the fair value of the underlying securities; and private equity investments are valued at the estimated fair value at the previous quarter end, which is based on the proportionate share of the underlying portfolio investments.

<table><tr><td></td><td>Real estate funds</td><td>Private equity</td><td>Total</td></tr><tr><td>Balance at December 31, 2017</td><td>$ 77.8</td><td>$20.9</td><td>$98.7</td></tr><tr><td>Actual return (loss) on plan assets:</td><td></td><td></td><td></td></tr><tr><td>Relating to assets still held at the reporting date</td><td>2.6</td><td>(0.3)</td><td>2.3</td></tr><tr><td>Relating to assets sold during the period</td><td>—</td><td>(0.8)</td><td>(0.8)</td></tr><tr><td>Purchases, sales and settlements</td><td>—</td><td>(6.6)</td><td>(6.6)</td></tr><tr><td>Balance at December 31, 2018</td><td>80.4</td><td>13.2</td><td>93.6</td></tr><tr><td>Actual return (loss) on plan assets:</td><td></td><td></td><td></td></tr><tr><td>Relating to assets still held at the reporting date</td><td>1.9</td><td>—</td><td>1.9</td></tr><tr><td>Relating to assets sold during the period</td><td>—</td><td>(1.4)</td><td>(1.4)</td></tr><tr><td>Purchases, sales and settlements</td><td>—</td><td>(3.2)</td><td>(3.2)</td></tr><tr><td>Balance at December 31, 2019</td><td>$ 82.3</td><td>$ 8.6</td><td>$90.9</td></tr></table>

The Company’s investment policies employ an approach whereby a diversified blend of equity and bond investments is used to maximize the long-term return of plan assets for a prudent level of risk. Equity investments are diversified across domestic and non-domestic stocks, as well as growth, value, and small to large capitalizations. Bond investments include corporate and government issues, with short-, mid- and long-term maturities, with a focus on investment grade when purchased. The Company’s target allocation to equity managers is between 30 to 60 percent with the remainder allocated primarily to bonds, real estate, private equity managers and cash. Investment and market risks are measured and monitored on an ongoing basis through regular investment portfolio reviews, annual liability measurements and periodic asset/liability studies.

The Company’s actual asset allocations are in line with target allocations. The Company regularly reviews its actual asset allocation and periodically rebalances its investments to the targeted allocation when considered appropriate.

There was no Company stock included in plan assets at December 31, 2019.

## 14. Derivative Instruments

The Company utilizes certain derivative instruments to enhance its ability to manage currency exposure as well as raw materials price risk. Derivative instruments are entered into for periods consistent with the related underlying exposures and do not constitute positions independent of those exposures. The Company does not enter into contracts for speculative purposes. The contracts are executed with major financial institutions with no credit loss anticipated for failure of the counterparties to perform.

## Cash Flow Hedges

With the exception of its net investment hedges, the Company designates that all of its hedging instruments are cash flow hedges. For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), gains or losses on the derivative instrument are reported as a component of other comprehensive loss, net of tax, and are reclassified into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings.

## Foreign Currency Forward Contracts

The Company is exposed to foreign currency exchange risk as a result of transactions in currencies other than the functional currency of certain subsidiaries. The Company utilizes foreign currency forward purchase and sale contracts to manage the volatility associated with foreign currency purchases, sales and certain intercompany transactions in the normal course of business. Principal currencies for which the Company utilizes foreign currency forward contracts include the British pound, Canadian dollar, Euro and Mexican peso.

Gains and losses on these instruments are recorded in accumulated other comprehensive loss, net of tax, until the underlying transaction is recorded in earnings. When the hedged item is realized, gains or losses are reclassified from accumulated other comprehensive loss to the consolidated statement of earnings. The assessment of effectiveness for forward contracts is based on changes in the forward rates. These hedges have been determined to be effective. The majority of the amounts in accumulated other comprehensive loss for cash flow hedges are expected to be reclassified into earnings within one year.

The following table summarizes, by currency, the contractual amounts of the Company’s foreign currency forward contracts that are designated as cash flow hedges:

<table><tr><td rowspan="2">December 31 (dollars in millions)</td><td colspan="2">2019</td><td colspan="2">2018</td></tr><tr><td>Buy</td><td>Sell</td><td>Buy</td><td>Sell</td></tr><tr><td>British pound</td><td>$ —</td><td>$ 1.3</td><td>$ —</td><td>$ 1.0</td></tr><tr><td>Canadian dollar</td><td>—</td><td>49.7</td><td>—</td><td>—</td></tr><tr><td>Euro</td><td>36.0</td><td>—</td><td>32.0</td><td>—</td></tr><tr><td>Mexican peso</td><td>18.6</td><td>—</td><td>27.8</td><td>—</td></tr><tr><td>Total</td><td>$ 54.6</td><td>$ 51.0</td><td>$ 59.8</td><td>$ 1.0</td></tr></table>

## Commodity Futures Contracts

In addition to entering into supply arrangements in the normal course of business, the Company also enters into futures contracts to fix the cost of certain raw material purchases, principally steel, with the objective of minimizing changes in cost due to market price fluctuations. The hedging strategy for achieving this objective is to purchase steel futures contracts on the New York Metals Exchange (NYMEX) and copper futures contracts on the open market of the London Metals Exchange (LME) or over the counter contracts based on the LME.

With NYMEX, the Company is required to make cash deposits on unrealized losses on steel derivative contracts.

## Net Investment Hedges

The Company enters into certain foreign currency forward contracts to hedge the exposure to a portion of the Company’s net investments in certain non-U.S. subsidiaries against the effect of exchange rate fluctuations on the translation of foreign currency balances to the U.S. dollar. For the derivative instruments that are designated and qualify as net investment hedges, gains and losses are reported in other comprehensive loss where they offset gains and losses recorded on the Company’s net investments in its non-U.S. subsidiaries. These hedges are determined to be effective. The Company recognized $ - and $7.4 million of after-tax gains associated with hedges of a net investment in non-U.S. subsidiaries in currency translation adjustment in other comprehensive income in 2019 and 2018, respectively. The contractual amount of the Company’s foreign currency forward contracts that are designated as net investment hedges is $100.0 million as of December 31, 2019.

The following tables present the impact of derivative contracts on the Company’s financial statements.

## 15. Income Taxes

The components of the provision (benefit) for income taxes consisted of the following:

<table><tr><td>Years ended December 31 (dollars in millions)</td><td>2019</td><td>2018</td><td>2017</td></tr><tr><td>Current:</td><td></td><td></td><td></td></tr><tr><td>Federal</td><td>$ 66.4</td><td>$ 60.1</td><td>$148.0</td></tr><tr><td>State</td><td>14.8</td><td>15.6</td><td>9.4</td></tr><tr><td>International</td><td>19.9</td><td>38.6</td><td>43.8</td></tr><tr><td>Deferred:</td><td></td><td></td><td></td></tr><tr><td>Federal</td><td>0.4</td><td>(1.7)</td><td>23.5</td></tr><tr><td>State</td><td>1.8</td><td>1.5</td><td>5.8</td></tr><tr><td>International</td><td>(1.2)</td><td>(0.5)</td><td>(6.2)</td></tr><tr><td></td><td>$102.1</td><td>$113.6</td><td>$224.3</td></tr></table>

The provision for income taxes differs from the U.S. federal statutory rate due to the following items:

<table><tr><td>Years ended December 31</td><td>2019</td><td>2018</td><td>2017</td></tr><tr><td>Provision at U.S. federal statutory rate</td><td>21.0%</td><td>21.0%</td><td>35.0%</td></tr><tr><td>State taxes, net of federal benefit</td><td>2.8</td><td>2.4</td><td>1.9</td></tr><tr><td>International income tax rate differential—China</td><td>(1.3)</td><td>(2.3)</td><td>(6.5)</td></tr><tr><td>International income tax rate differential—other</td><td>0.4</td><td>1.1</td><td>0.1</td></tr><tr><td>U.S. manufacturing credit</td><td>—</td><td>—</td><td>(1.4)</td></tr><tr><td>Research tax credits</td><td>(0.4)</td><td>(0.5)</td><td>(0.3)</td></tr><tr><td>Excess tax benefit on stock compensation</td><td>(0.5)</td><td>(0.4)</td><td>(2.2)</td></tr><tr><td>Other</td><td>(0.4)</td><td>(0.9)</td><td>0.8</td></tr><tr><td></td><td>21.6%</td><td>20.4%</td><td>27.4%</td></tr><tr><td>U.S. Tax Cuts &amp; Jobs Act (U.S. Tax Reform)</td><td>—</td><td>—</td><td>15.7</td></tr><tr><td></td><td>21.6%</td><td>20.4%</td><td>43.1%</td></tr></table>

U.S. Tax Reform was enacted on December 22, 2017 and significantly changed U.S. corporate income tax laws. Among other things, U.S. Tax Reform reduced the U.S. corporate income tax rate to 21 percent commencing on January 1, 2018, implemented a territorial tax system and levied a one-time mandatory tax on undistributed earnings of foreign subsidiaries of U.S. companies.

As a result of U.S. Tax Reform, the Company recorded income tax expense of $81.8 million in the fourth quarter of 2017. The income tax expense resulting from U.S. Tax Reform was included in the provision for income taxes on the Company’s consolidated statement of earnings and consisted of two components: $83.5 million of income tax expense related to the one-time mandatory tax on undistributed foreign earnings and a $1.7 million income tax benefit resulting from the remeasurement of the Company’s U.S. deferred tax assets and liabilities based on the lower U.S. corporate income tax rate. As permitted under the SEC Staff Accounting Bulletin 118, the amounts recorded during 2017 were subject to revisions in 2018.

The Company completed its accounting for the income tax effects of U.S. Tax Reform as of December 31, 2018 and determined that there was no material adjustment necessary to the provisional amounts it recorded in 2017. As allowed under ASU 2018-02 Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, the Company has elected not to reclassify the income tax effects of U.S. Tax Reform from accumulated other comprehensive losses to retained earnings.

Components of earnings before income taxes were as follows:

<table><tr><td>Years ended December 31 (dollars in millions)</td><td>2019</td><td>2018</td><td>2017</td></tr><tr><td>U.S.</td><td>$400.3</td><td>$376.0</td><td>$329.9</td></tr><tr><td>International</td><td>71.8</td><td>181.8</td><td>190.9</td></tr><tr><td></td><td>$472.1</td><td>$557.8</td><td>$520.8</td></tr></table>

Total income taxes paid by the Company amounted to $116.6 million, $116.4 million, and $131.1 million in 2019, 2018 and 2017, respectively.

## 15. Income Taxes (continued)

As of December 31, 2019, the Company has $20.8 million accrued for its estimate of withholding taxes due upon repatriation of undistributed foreign earnings it considers to be not permanently reinvested. As of December 31, 2019, $548.6 million of cash and cash equivalents and marketable securities were held by its foreign subsidiaries.

The tax effects of temporary differences of assets and liabilities between income tax and financial reporting are as follows:

<table><tr><td rowspan="2">December 31 (dollars in millions)</td><td colspan="2">2019</td><td colspan="2">2018</td></tr><tr><td>Assets</td><td>Liabilities</td><td>Assets</td><td>Liabilities</td></tr><tr><td>Employee benefits</td><td>$ 27.3</td><td>$ —</td><td>$ 32.5</td><td>$ —</td></tr><tr><td>Product liability and warranties</td><td>39.7</td><td>—</td><td>42.5</td><td>—</td></tr><tr><td>Inventories</td><td>—</td><td>0.3</td><td>—</td><td>0.6</td></tr><tr><td>Accounts receivable</td><td>16.3</td><td>—</td><td>18.3</td><td>—</td></tr><tr><td>Property, plant and equipment</td><td>—</td><td>34.9</td><td>—</td><td>36.3</td></tr><tr><td>Intangibles</td><td>—</td><td>61.3</td><td>—</td><td>57.3</td></tr><tr><td>Environmental liabilities</td><td>1.9</td><td>—</td><td>2.1</td><td>—</td></tr><tr><td>Undistributed foreign earnings</td><td>—</td><td>20.8</td><td>—</td><td>28.9</td></tr><tr><td>Tax loss and credit carryovers</td><td>15.2</td><td>—</td><td>17.5</td><td>—</td></tr><tr><td>All other</td><td>7.7</td><td>—</td><td>4.0</td><td>—</td></tr><tr><td>Valuation allowance</td><td>(11.9)</td><td>—</td><td>(13.1)</td><td>—</td></tr><tr><td></td><td>$ 96.2</td><td>$ 117.3</td><td>$103.8</td><td>$ 123.1</td></tr><tr><td>Net liability</td><td></td><td>$ 21.1</td><td></td><td>$ 19.3</td></tr></table>

The Company believes it is more likely than not that it will realize its deferred tax assets through the reduction of future taxable income. The Company considered historical operating results in determining the probability of the realization of the deferred tax assets.

A reconciliation of the beginning and ending amounts of tax loss carryovers, credit carryovers and valuation allowances is as follows:

<table><tr><td rowspan="2"></td><td colspan="2">Net Operating Losses and Tax Credits</td><td colspan="2">Valuation Allowances</td></tr><tr><td>2019</td><td>2018</td><td>2019</td><td>2018</td></tr><tr><td>Beginning balance</td><td>$ 17.5</td><td>$ 19.8</td><td>$ 13.1</td><td>$ 15.0</td></tr><tr><td>Reductions</td><td>(2.3)</td><td>(2.3)</td><td>(1.2)</td><td>(1.9)</td></tr><tr><td>Ending balance</td><td>$ 15.2</td><td>$ 17.5</td><td>$ 11.9</td><td>$ 13.1</td></tr></table>

The Company has foreign net operating loss carryovers that expire in 2020 through 2027 and state and local net operating loss carryovers that expire between 2029 and 2030.

A reconciliation of the beginning and ending amount of unrecognized benefits is as follows:

<table><tr><td>(Dollars in millions)</td><td>2019</td><td>2018</td></tr><tr><td>Balance at January 1</td><td>$8.3</td><td>$6.2</td></tr><tr><td>Additions for tax positions of prior years</td><td>1.4</td><td>2.1</td></tr><tr><td>Balance at December 31</td><td>$9.7</td><td>$8.3</td></tr></table>

The amount of unrecognized tax benefits that, if recognized, would affect the effective income tax rate is $0.8 million. The Company recognizes potential interest and penalties related to unrecognized tax benefits as a component of income tax expense. At December 31, 2019, there was an immaterial amount of interest and penalties accrued. The Company anticipates that there will not be a material decrease in the total amount of unrecognized tax benefits in 2020. The Company’s U.S. federal income tax returns and its U.S. state and local income tax returns are subject to audit for the years 2016-2019 and 2002-2019, respectively. The Company is subject to non-U.S. income tax audits for the years 2013-2019.

## 16. Commitments and Contingencies

## Environmental Contingencies

The Company is a potentially responsible party in judicial and administrative proceedings seeking to clean up sites which have been environmentally impacted. In each case, the Company has established reserves, insurance proceeds and/or a potential recovery from third parties. The Company believes any environmental claims will not have a material effect on its financial position or results of operations.

## Product Liability and Other Matters

The Company is subject to various claims and pending lawsuits for product liability and other matters arising out of the conduct of the Company’s business. With respect to product liability claims, the Company has self-insured a portion of its product liability loss exposure for many years. The Company has established reserves and has insurance coverage, which it believes are adequate to cover incurred claims. For the years ended December 31, 2019 and 2018, the Company had $125 million of product liability insurance for individual losses in excess of $7.5 million. The Company periodically reevaluates its exposure on claims and lawsuits and makes adjustments to its reserves as appropriate. The Company believes, based on current knowledge, consultation with counsel, adequate reserves and insurance coverage that the outcome of such claims and lawsuits will not have a material adverse effect on the Company’s financial position, results of operations or cash flows.

## Inventory Repurchase Arrangements

The Company maintains a commercial relationship with a supply-chain service provider (the Provider) in connection with the Company’s business in China. In this capacity, the Provider offers order-entry, warehousing and logistics support. The Provider also offers asset-backed financing to certain of the Company’s distributors in China to facilitate their working capital needs. To facilitate its financing support business, the Provider has collateralized lending facilities in place with multiple Chinese banks under which the Company has agreed to repurchase inventory if both requested by the banks and certain defined conditions are met, primarily related to the aging of the distributors’ notes.

The Provider is required to indemnify the Company for any losses the Company would incur in the event of an inventory repurchase under these arrangements. Potential losses under the repurchase arrangements represent the difference between the repurchase price and net proceeds from the resale of product plus costs incurred in the process, less related distributor rebates.

Before considering any reduction of distributor rebate accruals of $14.1 and $25.1 million as of December 31, 2019 and December 31, 2018, respectively, and from the resale of the related inventory, the gross amount the Company would be obligated to repurchase, which would be contingent on the default of all of the outstanding loans, was approximately $23.1 million and $75.8 million as of December 31, 2019 and December 31, 2018, respectively. The Company’s reserves for estimated losses under repurchase arrangements were immaterial as of December 31, 2019 and December 31, 2018.

In January 2020, an outbreak of a novel coronavirus (COVID-19) surfaced in Wuhan, China. The outbreak caused the Chinese government to require businesses to close and to restrict certain travel within the country. In cooperation with the government authorities, the Company’s operations in China extended their Chinese New Year holiday shut down by approximately one to two weeks. As of the date of this filing, the Company has resumed operations, but at below normal levels. The majority of the stores where the Company’s products are sold have temporarily closed and most of the stores that remain open are operating with reduced hours and are experiencing significant declines in customer traffic. In addition, as a significant portion of the Company’s products in China require installation by a professional, actions taken to contain the spread of the virus have, in certain cases, limited access for installation. The duration and intensity of the impact of the coronavirus and resulting disruption to the Company’s operations is uncertain. While our global supply chains are currently not affected, it is unknown whether or how they may be affected if such an epidemic persists for an extended period. While not yet quantifiable, the Company expects this situation will have a material adverse impact to its operating results in the first quarter of 2020 and continues to assess the financial impact for the remainder of the year.

## Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (“the Exchange Act”)) as of the end of the period covered by this report. Based on the evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period our disclosure controls and procedures are effective in recording, processing, summarizing, and reporting, on a timely basis, information required to be disclosed by us in the reports that we file or submit under the Exchange Act, and that information is accumulated and communicated to the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely discussions regarding required disclosure.

## Management Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)). Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our internal control over financial reporting based on the Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). As allowed by Securities and Exchange Commission guidance, management excluded from its assessment Water-Right, which was acquired in 2019 and constituted 3.6 percent and 6.3 percent of total assets and net assets, respectively, as of December 31, 2019 and 1.5 percent and 1.4 percent of net sales and net earnings, respectively, for the year then ended. Based on this evaluation, our management has concluded that, as of December 31, 2019, our internal control over financial reporting was effective.

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

Ernst & Young LLP, an independent registered public accounting firm, has audited our consolidated financial statements and the effectiveness of internal controls over financial reporting as of December 31, 2019 as stated in their report which is included herein.

## Changes in Internal Control Over Financial Reporting

There have been no changes in the company’s internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) during the year ended December 31, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

## REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders
A. O. Smith Corporation

## Opinion on Internal Control over Financial Reporting

We have audited A. O. Smith Corporation’s internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, A. O. Smith Corporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on the COSO criteria.

As indicated in the accompanying Management Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Water-Right, Inc., which is included in the 2019 consolidated financial statements of the Company and constituted 3.6 percent and 6.3 percent of total assets and net assets, respectively, as of December 31, 2019 and 1.5 percent and 1.4 percent of net sales and net earnings, respectively, for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of Water-Right, Inc.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of A. O. Smith Corporation as of December 31, 2019 and 2018, and 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, 2019, and the related notes and financial statement schedule listed in the index at Item 15(a) and our report dated February 24, 2020 expressed an unqualified opinion thereon.

## Basis for Opinion

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

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

## Definition and Limitations of Internal Control Over Financial Reporting

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

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