A. O. SmithWholesale Channel Adapting to Changing Markets, Customers Wholesale distribution is A. O. Smith’s largest water heater market channel and has been since the company began selling residential water heaters more than 70 years ago. Today, as market channels blur due to online technologies and changing consumer preferences, the wholesale channel continues to adapt its business model to the changing competitive environment. Despite the changes, wholesale distribution remains positioned to thrive in the long term, due to a number of factors: • As water heaters become more complex, they require professional installation. Wholesale distribution is closely aligned with plumbing contractors; • Distributors remain the major driver in commercial water heating due to innovative programs that make products and support available 24/7; • Wholesale distribution, with its extensive logistics capabilities, is well-adapted to serve the new construction market. Wholesale distributors are responding to a new generation of consumers who are more engaged in any purchase that affects their homes. Whereas, in the past, many wholesalers discouraged direct consumer contact, today they are opening large, well-appointed showrooms and utilizing digital marketing tools to attract customers, particularly millennials. The term for this approach is “omni-channel,” which means creating the same environment for a customer no matter how he or she wants to shop. Senior Leadership Charles T.

Wheeler Senior Vice President and General Manager- North America, India, Europe & Export The upgraded product sizing APP is designed to help plumbing contractors guide consumers through the water heater selection process. The new APP is the latest in a series of online tools designed to help plumbing contractors offer more value to their customers. Engineering Technician Jamie Wilks checks the remote monitoring capability of a Cyclone® series 300 high efficiency water heater under test in the commercial product engineering center. The Cyclone 300, which was introduced in January, offers remote monitoring through a smart phone APP to help customers keep tabs on water heater performance. Over the last several years, A. O. Smith has developed a number of tools and services to support its valued partners in the wholesale distribution channel, and that effort will continue in 2017. One of the most visible services is the contractor locator, a lead-generation tool provided on our wholesale websites. The locator uses proprietary geo-locating algorithms to help consumers find a qualified plumber near their home who can install or service their water heater. As products become more diverse and more complex, consumers are asking for assistance in selecting the right water heater for their homes. To meet this need, A. O. Smith has developed an exclusive product sizing tool, available online or as an APP for plumbers to download. The new tool allows plumbers to take a consulting approach in helping guide customers through the water heater sizing and selection process. To further assist with the selection process, A. O. Smith includes rating and reviews for residential water heaters on its web properties. Another important new tool is the Green Sky® consumer financing program that plumbing contractors can offer to their customer. The financing covers not just the water heater, but also installation, and other plumbing services. Overcoming the up- front cost of a water heater purchase has been a barrier to more adoption of energy efficient technologies, and this financing tool has enabled contractors to effectively offer these solutions to their customers. All of these programs are designed to drive business to the company’s channel partners, particularly plumbing contractors. This, combined with the constant introduction of new residential and commercial products, will help the wholesale distribution channel continue to enjoy success for years to come. 11270 West Park Place P.O.

We repurchased more than three million shares of company stock at an approximate cost of $135 million. In January, we announced a 17 percent increase in the company’s quarterly cash dividend, the 12th consecutive year in which we raised the dividend. In August, the company entered the North American water treatment market with the acquisition of Aquasana, Inc., of Austin, Texas. Aquasana manufactures an extensive line of premium water treatment products, ranging from point- of-entry systems for the home and on-the-go products such as portable filter bottles. Aquasana markets its products directly to consumers, with 80 percent of sales coming from its web site and call center located just outside Fort Worth. We believe this new business presents us with numerous opportunities, as consumers are becoming more aware of water quality issues throughout the U.S. and are seeking healthier alternatives for their families. We also anticipate revenue synergies as we take Aquasana products to our existing businesses in China and India and introduce our patented reverse osmosis products to U.S. consumers. Growth Strategy: Organic Growth China: Lochinvar brands: NA water heaters & other: 32% of sales growing 15% 4.8% 11% of sales growing 8% .9% 57% of sales growing 4% 2.3% Total annual sales growth 8.0% The North American segment unit reported sales increased to $1.74 billion, a 14 percent increase in operating profits to $385.9 million and an impressive 200 basis point increase in operating margin. Higher volumes of boilers and commercial water heaters contributed to the sales increase, and the team in Canada did an excellent job of growing the business in spite of the challenges coming from the strong U.S. dollar. Although sales of Lochinvar-branded products did not increase at the pace we expected, we did add share in the important high-efficiency condensing boiler market. With a large installed base of older, inefficient cast iron boilers in North America, we believe there is room for further growth in this market segment. After a number of years focused on meeting new government efficiency standards, we are now turning our sights to new product development, and 2017 promises to be a busy year in both the commercial and residential segments. Chief among these new products are: • The Cyclone® series 300 with an integrated touchscreen and remote monitoring capability; • The Lochinvar Noble combi boiler that allows us to enter a portion of the residential boiler market in which we were not participating; • The ProLine® series of commercial-grade residential water heaters. These units feature a number of commercial quality components developed by APCOM and, in some cases, come with an eight-year warranty; and • A full suite of electric tankless water heaters, a line of products we have not offered in the past. The Rest of World segment experienced a sales increase of 11 percent to $965.6 million, operating earnings of $129.1 million, a 14 percent increase, and operating margins of 13.4 percent. Our operations in China continue to outperform the Chinese economy, as we take advantage of the well-known A. O. Smith brand in that market. Sales of gas tankless water heaters increased more than 20 percent, while heat pump and other renewable water heater technologies also grew at double-digit rates (all measured in local currency). A sizable percentage of our sales are coming from the e-commerce channel, with revenues of nearly $200 million last year. Water treatment products continue to grow at a fast pace, as sales increased nearly 40 percent in the local currency over the prior year. In addition, sales of our air purification line of products nearly tripled over the prior year as Chinese consumers became aware of the air pollution problems in large parts of the country. To meet the demand for water treatment and air purification products, we began construction of a new 700,000 square foot plant in Nanjing during the fourth quarter of 2016. The new plant, which also will include new product engineering and quality labs, will begin production early next year. Looking ahead, we expect to achieve our eight percent revenue growth model in 2017 as we benefit from an incremental $40 million in Aquasana sales, improved residential water heater sales in the U.S. and continued commercial water heater and boiler sales increases. China’s growth will continue to outpace that country’s economy as we will benefit from household formation, market share gains and higher average selling prices in the water heater market, and the water treatment and air purification product lines once again experience double-digit growth. This outlook is tempered by the likelihood of higher material costs—most notably steel—and the U.S. dollar’s impact on Chinese, Canadian, and other foreign currencies. Nonetheless, I have confidence in the A. O. Smith team and its ability to meet these challenges—as they have in the past—and succeed. Everyone throughout our organization is focused on the Fundamentals for Success, the foundation for everything we do as a company: • Live our values which define who we are, how we do business, and the relationship we have with our customers, suppliers, and the communities in which we do business; • Relentlessly take care of the customer, obsessively understand what our customers want and need in order for them to succeed—and then deliver on those needs; • Invest in innovation in order to provide our customers with market-leading products and solutions; and • Invest in our people by giving them the training, tools, and knowledge to take care of customers and provide employees with the opportunity to grow to their fullest potential. Together, these four fundamentals contribute to A. O. Smith’s profitable growth. They have served us extremely well for the last 143 years, and I’m certain they will continue to serve us, in 2017 and beyond. Ajita G. Rajendra Chairman and Chief Executive Officer Letter to Shareholders March 2017 A. O. Smith once again enjoyed record-setting results in 2016. Sales increased six percent (eight percent in local currency) to more than $2.69 billion, the seventh consecutive year of record revenue performance. A number of factors contributed to the sales record, most notably impressive 19 percent sales growth (in local currency) for our China operations and continued demand for our commercial water heater and high-efficiency boiler products. Our global water treatment product sales increased to $194 million thanks to growth of 35 percent in China and the addition of Texas-based water treatment company Aquasana, which we acquired in August. Our earnings performance also set a record, increasing 17 percent to $1.85 per share. The higher commercial water heater and boiler volumes and continued double-digit sales growth in China, combined with improved pricing and lower material costs during the first half of the year contributed to the earnings improvement. Earnings were partially offset by lower U.S. residential water heater sales and higher selling costs in China to support expansion into the Tier 2 and Tier 3 cities as well as higher advertising costs to support brand building and the expansion of the air purification product line. Cash flow from operating activities increased an impressive 27 percent to $447 million.

Kempken Vice President & Controller John J. Kita Executive Vice President & Chief Financial Officer In August 2016 A. O. Smith acquired Aquasana, Inc. which designs, assembles and markets premium performance water purification products, including whole-house purification systems which are highlighted above. Water Treatment Business Enters the U.S. and Continues to Expand Globally Water quality needs for U.S. consumers continue to evolve with an aging and deteriorating water infrastructure and an increase in consumer awareness of water quality problems, including unhealthy drinking water throughout the country. Responding to these trends, A. O. Smith entered into the North American market in August 2016 with the acquisition of Texas-based Aquasana, Inc. which designs, assembles and markets premium performance water treatment products. Aquasana sells its whole-house treatment systems, drinking water solutions for at home and on-the-go and shower filters directly to U.S. consumers via www.aquasana.com, as well as its Texas-based call center and direct to the consumer, and through retail outlets and distributers. Aquasana’s drinking water filters remove over 66 harmful contaminants from water including chlorine, chloramines, pharmaceuticals, herbicides, pesticides, industrial solvents, lead, asbestos, and mercury and are engineered to preserve the healthy minerals in water, including calcium, magnesium and potassium. In 2016, the company continued to expand its water treatment line-up around the world, with major advancements in China, India and Turkey and the expansion into Vietnam as well. • China: Nanjing Water Treatment (NWT) started construction on a new 700,000 square foot plant, which is scheduled to begin production in 2018. The new plant will manufacture residential and commercial water treatment products, air purifiers and water softeners. The company also launched a new line of Wifi intelligent reverse osmosis (RO) water treatment products, which can be paired through an APP on a smart-device to alert consumers to any issues. The NWT team recently entered the commercial water treatment market in 15 major markets in China. • India: A. O. Smith entered four additional markets including: Hyderabad, Pune, Kolkata, and Chennai. The company introduced five new water treatment products in 2016 and expanded beyond the RO category with the launch of a unique UV water treatment that offers both ambient and hot water. The two new under-the-counter products, provide a digital display and alarm systems, unique in the industry for under the counter products, and the two new RO models allow for dispensing water at a touch of a button (i.e. electronic faucets). • Turkey: A. O. Smith expanded its presence in the residential and light commercial channels in Istanbul and Ishmair through an exclusive dealer network in those cities. Two new RO units, the Lotus and the Daisy, were also introduced in 2016. • Vietnam: Sales reached $3.5 million in 2016, as the Vietnam team continues to focus its efforts on selling premium RO water treatment products using the patented side-stream membrane technology and continues to develop their sales channels in that country. The Flint, Michigan, water crisis and the continued lead contamination issues throughout the U.S. have created greater consumer awareness of water quality issues; however, more education is needed to inform consumers about Chromium 6, Teflon, and other drinking water contaminants. In addition to marketing innovative, effective water treatment products, A. O. Smith will continue to be a thought leader in this important global industry. In 2016 the company began construction on a new 700,000 square foot plant, which will manufacture residential and commercial treatment products, air purifiers and water softeners in Nanjing, China. shareholders.

Smith China Wallace E. “Eddie” Goodwin President & Chief Operating Officer- Lochinvar, LLC Dr. Robert J. Heideman Senior Vice President- Chief Technology Officer Daniel L. Kempken Vice President & Controller John J. Kita Executive Vice President & Chief Financial Officer In August 2016 A. O. Smith acquired Aquasana, Inc. which designs, assembles and markets premium performance water purification products, including whole-house purification systems which are highlighted above. Water Treatment Business Enters the U.S. and Continues to Expand Globally Water quality needs for U.S. consumers continue to evolve with an aging and deteriorating water infrastructure and an increase in consumer awareness of water quality problems, including unhealthy drinking water throughout the country. Responding to these trends, A. O. Smith entered into the North American market in August 2016 with the acquisition of Texas-based Aquasana, Inc. which designs, assembles and markets premium performance water treatment products. Aquasana sells its whole-house treatment systems, drinking water solutions for at home and on-the-go and shower filters directly to U.S. consumers via www.aquasana.com, as well as its Texas-based call center and direct to the consumer, and through retail outlets and distributers. Aquasana’s drinking water filters remove over 66 harmful contaminants from water including chlorine, chloramines, pharmaceuticals, herbicides, pesticides, industrial solvents, lead, asbestos, and mercury and are engineered to preserve the healthy minerals in water, including calcium, magnesium and potassium. In 2016, the company continued to expand its water treatment line-up around the world, with major advancements in China, India and Turkey and the expansion into Vietnam as well. • China: Nanjing Water Treatment (NWT) started construction on a new 700,000 square foot plant, which is scheduled to begin production in 2018. The new plant will manufacture residential and commercial water treatment products, air purifiers and water softeners. The company also launched a new line of Wifi intelligent reverse osmosis (RO) water treatment products, which can be paired through an APP on a smart-device to alert consumers to any issues. The NWT team recently entered the commercial water treatment market in 15 major markets in China. • India: A. O. Smith entered four additional markets including: Hyderabad, Pune, Kolkata, and Chennai. The company introduced five new water treatment products in 2016 and expanded beyond the RO category with the launch of a unique UV water treatment that offers both ambient and hot water. The two new under-the-counter products, provide a digital display and alarm systems, unique in the industry for under the counter products, and the two new RO models allow for dispensing water at a touch of a button (i.e. electronic faucets). • Turkey: A. O. Smith expanded its presence in the residential and light commercial channels in Istanbul and Ishmair through an exclusive dealer network in those cities. Two new RO units, the Lotus and the Daisy, were also introduced in 2016. • Vietnam: Sales reached $3.5 million in 2016, as the Vietnam team continues to focus its efforts on selling premium RO water treatment products using the patented side-stream membrane technology and continues to develop their sales channels in that country. The Flint, Michigan, water crisis and the continued lead contamination issues throughout the U.S. have created greater consumer awareness of water quality issues; however, more education is needed to inform consumers about Chromium 6, Teflon, and other drinking water contaminants. In addition to marketing innovative, effective water treatment products, A. O. Smith will continue to be a thought leader in this important global industry. In 2016 the company began construction on a new 700,000 square foot plant, which will manufacture residential and commercial treatment products, air purifiers and water softeners in Nanjing, China.

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, gas tankless and electric water heaters, as well as water treatment products. Both segments primarily manufacture and market in their respective regions of the world. Our North America segment also manufactures and globally markets specialty commercial water heating equipment, condensing and non-condensing boilers and water systems tanks. We also manufacture and market in-home air purification products in China. The following table summarizes our sales. This summary and all other information presented in this section should be read in conjunction with the Consolidated Financial Statements and Notes to Consolidated Financial Statements, which appear in Item 8 in this document. North America Rest of World Inter-segment Total Sales NORTH AMERICA Years Ended December 31 (dollars in millions) 2016 $ 1,743.2 2015 $ 1,703.0 2014 $ 1,621.7 2013 $ 1,520.0 2012 $ 1,430.8 965.6 866.1 768.3 668.0 542.5 (22.9) (32.6) (34.0) (34.2) (34.0) $ 2,685.9 $ 2,536.5 $ 2,356.0 $ 2,153.8 $ 1,939.3 Sales in our North America segment increased 2.4 percent, or $40.2 million, in 2016 compared with the prior year. The sales increase in 2016 was the result of price increases in the U.S. for residential and commercial water heaters and higher volumes of commercial water heaters and boilers in the U.S. Lower volumes of U.S. residential water heaters partially offset these favorable factors. Our acquisition of Aquasana, Inc. (Aquasana) a water treatment company, in August 2016, added approximately $18 million of sales in 2016 compared with 2015. 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 12,000 gallon products with varying efficiency ranges. We offer electric, natural gas, gas tankless and liquid propane models as well as solar tank units. Our North American residential water heater sales in 2016 totaled approximately $1.1 billion or 62 percent of North America sales. 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 40,000 British Thermal Units (BTUs) to 6.0 million BTUs. Our commercial boilers are primarily used in space heating applications for hospitals, schools, hotels and other large commercial buildings. Other. In our North America segment, we also assemble and market water treatment products, primarily for the U.S. 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 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 market, we believe our comprehensive product line including boilers and our high-efficiency products give us a competitive advantage in this portion of the water heating industry. Our wholesale distribution channel includes more than 1,200 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 five of the seven largest national hardware and home center chains, including a long-standing exclusive relationship with Lowe’s. Our commercial boiler distribution channel is primarily comprised of manufacturer representative firms. Our water treatment products are primarily sold directly to consumers through e-commerce. 3 Our Lochinvar brand is one of the leading residential and commercial boiler brands in the U.S. Approximately 40 percent of Lochinvar-branded sales consist of residential and commercial water heaters while the remaining 60 percent of Lochinvar- branded sales consist primarily of boilers and related parts. Our Aquasana brand is one of the leading brands in the direct to consumer portion of the water treatment industry in the U.S. Our energy efficient product offerings continue to be a sales driver for our business. Our Cyclone product family 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. 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, product performance, maintenance costs and price. Our principal water heating and boiler competitors in North America include Rheem, Bradford White, Rinnai, Aerco and Navien. Numerous other manufacturing companies also compete. Our principal water treatment competitors in the U.S. are Brita, Culligan and Ecowater. REST OF WORLD Sales in our Rest of World segment increased 11.5 percent, or $99.5 million, in 2016 compared with the prior year. A 12.5 percent increase in sales in China to $887.9 million was the primary source of the increase. Excluding the appreciation of the U.S. dollar in 2016, sales in China increased 18.9 percent in 2016. 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 and solar water heaters. We believe we are one of the leading suppliers of water heaters to the residential market in China, with a broad product offering including electric, gas, gas tankless, heat pump and solar units as well as combi boilers. Primarily for Asia, we also manufacture and market water treatment products and air purification products. We sell water heaters in more than 9,000 retail outlets in China, of which over 2,500 exclusively sell our products. Our water treatment products and air purification products are sold in over 6,500 and 2,500 retail outlets in China, respectively. Our e- commerce sales continue to grow in China reaching nearly $200 million in 2016. 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 total sales in India were $18.2 million in 2016 compared with $15.9 million in 2015. Our primary competitor in China is Haier Appliances, a Chinese company, but we also compete with Midea in the electric water heater and water treatment markets and Rinnai and Noritz in the gas tankless water heater market. Additionally, we compete with numerous other Chinese private and state-owned water heater and water treatment companies in China. Our principal competitors in the China air purification market are Phillips, Panasonic and Sharp. In India, we compete with Bajaj and MTS-Racold 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 Turkey and Vietnam, all of which combined comprised six percent of total Rest of World sales in 2016. 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. 4 RESEARCH AND DEVELOPMENT To improve our competitiveness by generating new products and processes, we conduct research and development at our Corporate Technology Center in Milwaukee, Wisconsin, at our Global Engineering Center in Nanjing, China, and at our operating locations. Our total expenditures for research and development in 2016, 2015 and 2014 were $80.1 million, $73.7 million and $67.9 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 15,500 employees as of December 31, 2016, primarily non-union. BACKLOG Due to the short-cycle nature of our businesses, none of our operations sustains significant backlogs. 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.

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 The global economy continues to show signs of stress and could stall or reverse the course of any recovery. If this were 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 filter products which could negatively impact our profitability and cash flows. In addition, a deterioration in current economic conditions, including credit market conditions, 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. We increasingly sell our products and operate outside the U.S., and to some extent, rely on imports and exports, which may present additional risks to our business Approximately 40 percent of our net sales in 2016 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 9,700 of our 15,500 employees as of December 31, 2016 were located in China. At December 31, 2016, approximately $752 million of cash, cash equivalents and marketable securities were held by our foreign subsidiaries, $558 million of which was located in China. International operations generally are subject to various risks, including: political, religious, and economic instability; local labor market conditions; the imposition of 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 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 portion of our business could be affected by a slowdown in the transition of the Chinese economy to a consumer driven ecomony Our sales growth in China has averaged approximately 18 percent per year in local currency over the past three years, and we anticipate sales growth of approximately 15 percent in local currency in 2017. We are expanding our manufacturing capacity for water treatment and air purification products in China to meet local demand. If there is a slowdown in the transition to a more consumer driven economy or the rate of urbanization was to stall, it could adversely affect our financial condition, results of operations and cash flows. 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 37 percent of our sales in 2016. 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 relationship 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. 6 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 The recovery in residential and commercial construction activity in North America remains fragile and construction could decline again after showing modest improvements in 2016. We believe that the majority of the markets we serve are for replacement of existing products and replacement related volume growth was strong in 2013 and 2014 before declining in 2015 and 2016. Changes in replacement volume and in the construction market could negatively affect us. 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 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, and some are increasingly expanding beyond their existing manufacturing or geographic footprints. Consumer purchasing behavior may shift to distribution channels, including e-commerce, which is a rapidly developing area. Development of a successful e-commerce strategy involves significant time, investment and resources. We cannot assure that our products and services will continue to compete successfully with those of our competitors or that we will 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 international operations are subject to risks related to foreign currencies We have significant operations outside of the U.S., primarily in China and Canada and to a lesser extent Europe and India, and therefore, hold assets, 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. As a result, we are subject to risks associated with operating in foreign countries, including fluctuations in currency exchange rates and interest rates, or hyperinflation in some foreign countries. Furthermore, typically our products are priced in foreign countries in local 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 are manufactured in the U.S. 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. If we are unable to develop product innovations and improve our technology and expertise, we could lose customers or market share Our success may depend on our ability to adapt to technological changes in the water heating, boiler and water treatment industries. If we are unable to timely develop and introduce new products, or enhance existing products, in response to changing market conditions or customer requirements or demands, our competitiveness could be materially and adversely affected. Our ability to 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. 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 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, or to industry standards, could substantially increase manufacturing costs, impact the size and timing of demand for our products, 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. 7 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 manufacture 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. We are subject to regulation of our 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. Impact of potential U.S. tax reform As of December 31, 2016, approximately $752 million of cash, cash equivalents and marketable securities were held by our foreign subsidiaries. We would incur a cost to repatriate these funds to the U.S. and have recorded a liability of approximately $42 million associated with the repatriation of a portion of those funds. Additionally, depending on tax proposals currently contemplated in the U.S. we could incur one-time income tax expenses associated with repatriation and the remeasurement of deferred income taxes. Retention of key personnel is important to our business Attracting and retaining talented employees is important to the continued success 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. 8 Sales growth of our Lochinvar-branded products could stall resulting in lower than expected revenues and earnings The compound annual growth rate of sales of our Lochinvar-branded products 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. In 2003, approximately five percent of the boilers sold in the U.S. were condensing boilers, and by 2015, the percentage had grown to approximately 43 percent. Our Lochinvar brand is a leader in residential and commercial condensing boilers. 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. 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, employees 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, failures on the part of third-party information system providers, natural disasters, power loss, telecommunications failures, viruses, or breaches of security. 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, 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. 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 While we will continue to evaluate potential acquisitions, we could use a significant portion of our available capital to fund future acquisitions. If we complete any future acquisitions, then 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. Our underfunded pension plans require future pension contributions which could limit our flexibility in managing our company Due to the significant negative investment returns in 2008, flat returns in 2015 and falling interest rates in recent years, the projected benefit obligations of our defined benefit pension plans exceeded the fair value of the plan assets by approximately $109 million at December 31, 2016. 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 are forecasting that we will not be required to make a contribution to the plan in 2017, 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 substantial portion of our cash flows from operations to making the contributions which could negatively impact our flexibility in managing the company. 9 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. 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, 2016, these members of the Smith Family own approximately 62.0 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 95.9 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 and shares of our Class A Common Stock, the Smith Family 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. 10 ITEM 1B - UNRESOLVED STAFF COMMENTS None. ITEM 2 - PROPERTIES Properties utilized by us at December 31, 2016 were as follows: North America In this segment we have 15 manufacturing plants located in six states and two non-U.S. countries, of which 11 are owned directly by us or our subsidiaries and four are leased from outside parties. The terms of leases in effect at December 31, 2016 expire between 2017 and 2025. Rest of World In this segment we have six manufacturing plants located in four non-U.S. countries, of which three are owned directly by us or our subsidiaries and three are leased from outside parties. Initial lease terms generally provide for minimum terms of one to six years and have one or more renewal options. The terms of leases in effect at December 31, 2016 expire between 2017 and 2020. 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 13 of Notes to Consolidated Financial Statements.

All references in this Item 5 to numbers of A. O. Smith Corporation shares or price per share have been adjusted to reflect the split. (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. Wells Fargo Shareowner Services, N.A., P.O. Box 64854, St. Paul, Minnesota, 55164-0854 serves as the registrar, stock transfer agent and the dividend reinvestment agent for our Common Stock and Class A Common Stock.

Dividends declared on the common stock are shown in Note 15 of Notes to Consolidated Financial Statements appearing elsewhere herein. (d) Stock Repurchases. In 2015, our Board of Directors authorized the purchase of an additional 4,000,000 shares of our Common Stock. In 2016, our Board of Directors authorized the purchase of an additional 3,000,000 shares of our Common Stock. Under the share repurchase program, our Common Stock may be purchased through a combination of Rule 10b5-1 automatic trading plan and discretionary purchases in accordance with applicable securities laws. The number of shares purchased and the timing of the purchase will depend on a number of factors, including share price, trading volume and general market conditions, as well as on 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 2016, we repurchased 3,273,109 shares at an average price of $41.30 per share and at a total cost of $135.2 million. As of December 31, 2016, there were 4,906,403 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 2016: ISSUER PURCHASES OF EQUITY SECURITIES Period October 1 – October 31, 2016 November 1 – November 30, 2016 December 1 – December 31, 2016 Total Number of Shares Purchased 236,150 249,008 240,997 Average Price Paid per Share $ 49.15 46.37 49.24 Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs 236,150 249,008 240,997 Maximum Number of Shares that may yet be Purchased Under the Plans or Programs 5,396,408 5,147,400 4,906,403 (e) Performance Graph.

(4) 16 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, gas tankless and electric water heaters, as well as water treatment products. Both segments primarily manufacture and market in their respective regions of the world. Our North America segment also manufactures and globally markets specialty commercial water heating equipment, condensing and non-condensing boilers and water systems tanks. Our Rest of World segment also manufactures and markets in-home air purification products in China. In 2016, our North America segment sales were $1,743.2 million and our Rest of World segment sales were $965.6 million. Sales of our products in China grew significantly in 2016, increasing 12.5 percent over 2015. Excluding the impact from the strengthening U.S. dollar, sales in China increased 18.9 percent in 2016. We expect sales in 2017 in China to grow at a rate of approximately 15 percent in local currency, as we believe overall water heater market growth, geographic expansion, market share gains, and growth in water treatment and air purification products will contribute to our growth. Price increases for residential and commercial water heaters and higher volumes of commercial water heaters and boilers contributed to 2016 sales increases in our North America segment. Partially offsetting these factors was a decline in residential water heater volumes in the U.S. We expect our North America residential and commercial water heater industry unit to show modest growth in 2017. Lochinvar-branded products contributed $300.6 million to our net sales in 2016, and we expect over eight percent sales growth of Lochinvar-branded products in 2017, driven by the continuing U.S. industry transition to higher efficiency products and our introduction of new products. Approximately 40 percent of Lochinvar-branded product sales consist of residential and commercial water heaters while the remaining 60 percent of Lochinvar-branded product sales consist primarily of boilers and related parts. Our stated acquisition strategy includes a number of our water-related strategic initiatives. We will look 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 the high growth regions demonstrated by our introduction of air purification products in China and water treatment products in India and Vietnam in 2015. Consistent with our stated strategy to expand our core product offering, we acquired Aquasana, Inc. (Aquasana) in August 2016. Aquasana designs, assembles and markets premium performance water treatment products, including whole-house treatment systems, drinking water solutions for at home and on-the-go, and shower filters. Aquasana sells products primarily directly to U.S. consumers through e-commerce, as well as through retail outlets and distributors. With a three year compound annual revenue growth rate of 17 percent as of December 31, 2016, Aqausana fits squarely within our stated strategy to expand our core product offerings to new geographies that present growth opportunities. RESULTS OF OPERATIONS Our sales in 2016 were a record $2,685.9 million surpassing 2015 sales of $2,536.5 million by 5.9 percent. Excluding the impact from the appreciation of the U.S. dollar against the Chinese currency that occurred in 2016, our sales grew approximately eight percent in 2016. The increase in sales in 2016 was primarily due to higher sales in China of water heaters, residential air purification products, as well as 35 percent sales growth of A. O. Smith-branded water treatment products. Sales in China grew 12.5 percent in 2016, and excluding the impact of the appreciation of the U.S. dollar, sales in China increased 18.9 percent in 2016. Our sales in 2016 also benefitted from price increases in the U.S., higher volumes of U.S. boilers and commercial water heaters as well as $18.4 million of sales of Aquasana-branded water treatment products resulting from our acquisition of Aquasana in August 2016. These items more than offset lower volumes of U.S. residential water heaters. Our sales in 2015 were higher than 2014 sales of $2,356.0 million by 7.7 percent. The increase in sales in 2015 was attributable to higher prices in North America, higher sales of Lochinvar-branded products and commercial water heaters in the U.S. as well as strong demand for our water heating and water treatment products in China. Sales of water heaters and water treatment products in China grew 13.7 percent in 2015 compared to 2014. Sales of water heaters and water treatment products in China grew 16.1 percent in 2015 compared to 2014, excluding impact of the appreciation of the U.S. dollar in 2015. Our gross profit margin in 2016 increased to 41.7 percent from 39.8 percent in 2015. The higher margin in 2016 was due to price increases in the U.S., lower material costs in the first half of 2016 and higher sales of boilers and commercial water heaters in the U.S. Our gross profit margin in 2015 increased from 36.5 percent in 2014 primarily due to price increases in the U.S. and Canada, higher U.S. sales of commercial water heaters and boilers, lower steel costs and a reduction in pension- related costs. 17 Selling, general and administrative (SG&A) expenses were $48.2 million higher in 2016 than in 2015. The increase in SG&A expenses in 2016 to $658.9 million was primarily due to higher selling costs supporting our sales efforts in tier 2 and tier 3 cities in China as well as higher advertising costs to support brand building in China. SG&A expenses were $38.6 million higher in 2015 than in 2014 primarily due to higher selling and engineering costs supporting increased volumes in China as well as higher costs associated with the 2015 launch of air purification products in China which more than offset lower pension costs in the U.S. Pension income in 2016 was $6.9 million compared to pension expense of $0.1 million in 2015 and $28.6 million in 2014. As of December 31, 2015, we changed to a more precise method to estimate the service cost and interest components of net periodic benefit cost for our pension and post-retirement plan. The change is the primary reason for the $7.1 million decrease in service and interest costs in 2016 compared to 2015. The significant decrease in pension expense in 2015 compared to 2014 was due to the sunset of our pension plan for the majority of our employees on December 31, 2014. In 2015, we began making additional Company contributions to a defined contribution plan in lieu of benefits earned in our pension plan. Interest expense was $7.3 million in 2016 compared to $7.4 million in 2015 and $5.7 million in 2014. The higher interest expense in 2015 compared to 2014 was primarily related to interest rates on term notes in the amount of $75 million issued in January 2015 that were higher than the interest rate on the revolving credit facility that it replaced as well as higher overall debt levels related to share repurchases. Other income was $9.4 million in 2016 compared to $10.8 million in 2015 and $5.2 million in 2014. The decrease in other income in 2016 compared to 2015 was primarily due to a decrease in interest income caused by lower interest rates in China in 2016. The increase in other income in 2015 compared to 2014 was primarily due to higher interest income resulting from a higher level of marketable securities during the year. Our effective tax rate was 29.4 percent in 2016, compared with 29.7 percent in 2015 and 27.5 percent in 2014. Our lower effective tax rate in 2016 compared to 2015 was primarily due to our adoption of a new accounting standard for share-based compensation that was partially offset by a change in geographic earnings mix. The higher effective tax rate in 2015 compared to 2014 was primarily due to a change in geographic earnings mix. North America Sales in our North America segment sales were $1,743.2 million in 2016 or $40.2 million higher than sales of $1,703.0 million in 2015. The sales increase in 2016 resulted from a full year of U.S. price increases for residential water heaters related to a regulatory change in April 2015, and an August 2016 price increase in the U.S. related to higher steel prices and other cost inflation. Sales in 2016 also benefitted from higher volumes of boilers and commercial water heaters in the U.S. as well as the addition of $18.4 million of sales of water treatment products resulting from our Aquasana acquisition. Lower volumes of U.S. residential water heaters partially offset these benefits. Sales in 2015 were $81.3 million higher than sales of $1,621.7 million in 2014. The sales increase in 2015 resulted from a price increase for residential water heaters in the U.S. due to a regulatory change in April 2015 and higher volumes of commercial water heaters and condensing commercial boilers in the U.S., partially offset by lower residential volumes in the U.S. and a decrease in the translated value of the Canadian dollar during 2015. North America operating earnings were $385.9 million in 2016 compared to operating earnings of $339.9 million and $238.7 million in 2015 and 2014, respectively. Operating margins were 22.1 percent, 20.0 percent and 14.7 percent in 2016, 2015 and 2014, respectively. The higher operating earnings and operating margin in 2016 compared to 2015 were primarily due to pricing actions in the U.S., lower material costs in the first half of 2016 and higher boiler and commercial water heater volumes in the U.S. that were partially offset by lower U.S. residential water heater volumes. The significantly higher operating earnings and operating margin in 2015 compared to 2014 were primarily due to higher prices in the U.S. and Canada, higher sales of Lochinvar-branded products and commercial water heaters in the U.S., lower steel costs and lower pension costs which more than offset lower residential water heater volumes in the U.S. We expect North America operating margin to be between 21.5 and 22.25 percent in 2017, despite the headwind from lower Aquasana margins of almost 50 basis points. Rest of World Sales in our Rest of World segment in 2016 were $965.6 million or $99.5 million higher than sales of $866.1 million in 2015. Sales in China grew 12.5 percent in 2016. Excluding the impact from the appreciation of the U.S. dollar in 2016, sales in China increased 18.9 percent in 2016 driven by higher demand for water heaters, water treatment products and residential air purification products. A. O. Smith-branded water treatment sales in China totaled $148 million in 2016 compared to $110 million in 2015. Sales of in-home air purification products were $26 million in 2016 compared to $9 million in 2015. Sales in 2015 were $97.8 million higher than sales of $768.3 million in 2014 due to higher demand for water heaters, approximately $35 million of incremental sales of water treatment products and approximately $9 million in sales of our newly launched in- home air purification products. Sales in China grew 13.7 percent in 2015. Excluding the impact from the appreciation of the U.S. dollar in 2015, sales in China increased 16.1 percent in 2015. 18 Rest of World operating earnings were $129.1 million in 2016 compared to operating earnings of $113.0 million and $106.7 million in 2015 and 2014, respectively. Segment operating margins were 13.4 percent in 2016 compared to 13.0 percent and 13.9 percent in 2015 and 2014, respectively. Higher operating earnings and operating margin in 2016 compared to 2015 were primarily due to higher sales in China that were partially offset by increased SG&A expenses in China. Higher selling costs in China to support our sales efforts in tier 2 and tier 3 cities and higher advertising costs to support brand building were the primary drivers of higher SG&A expenses. Operating earnings in 2016 were also negatively impacted by almost $8 million due to the appreciation of the U.S. dollar in 2016. Higher operating earnings in 2015 were primarily due to higher sales in China and lower steel costs that were partially offset by lower sales of highly profitable commercial water heaters in China, increased SG&A expenses and approximately $1.5 million of higher losses in India compared to 2014. Earnings in China were reduced by approximately $2.5 million due to the appreciation of the U.S. dollar in 2015. Higher selling and engineering costs in China as well as higher SG&A costs associated with the 2015 launch of air purification products were the primary drivers for decreased operating margins in 2015 as compared to 2014. We expect 2017 operating margin to exceed 14 percent. LIQUIDITY AND CAPITAL RESOURCES Our working capital was $796.4 million at December 31, 2016 compared with $750.1 million and $713.8 million at December 31, 2015 and December 31, 2014, respectively. Cash generated in China and sales-related increases in accounts receivable, inventory and accounts payable levels explain the majority of the increase in 2016 and 2015. As of December 31, 2016, essentially all of our $754.6 million of cash, cash equivalents and marketable securities were held by our foreign subsidiaries. We would incur a cost to repatriate these funds to the U.S. and have an accrual of $42.3 million for the repatriation of a portion of these funds. Cash provided by operating activities during 2016 was $446.6 million compared with $351.7 million during 2015 and $264.0 million during 2014. The increase in cash flows in 2016 was primarily due to higher earnings from operations and lower outlays for working capital. We experienced a series of favorable cash flow impacts in China in the fourth quarter of 2016, including: • A decline in accounts receivable balances from the prior year-end, despite higher fourth quarter sales in 2016. We received a series of unanticipated large customer payments late in the fourth quarter of 2016 and benefitted from improved terms with a few customers, all resulting in lower accounts receivable balances; • An increase in trade payable balances most notably due to higher inventory in advance of the spring festival occurring in China in the last week in January; and • Higher receipts of cash in advance of sales from distribution customers. The improvement in cash flows in 2015 was primarily due to higher earnings from operations and lower outlays for working capital driven primarily by increases in accounts payable balances in China. We expect cash provided by operating activities in 2017 to be approximately $350 million. We expect higher earnings in 2017 to be more than offset by larger outlays for working capital due to the higher than anticipated cash flows in the fourth quarter of 2016. Over the two-year period from 2016 to 2017, we expect to generate operating cash of approximately $800 million, which compares with $616 million of operating cash flows during 2014 to 2015. Our capital expenditures were $80.7 million in 2016, $72.7 million in 2015 and $86.1 million in 2014. 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. Included in 2016 capital expenditures were approximately $13 million related to capacity expansion in China as well as approximately $11 million related to our enterprise resource planning (ERP) system implementation. Included in 2015 capital expenditures were approximately $16 million related to our ERP implementation and approximately $19 million related to capacity expansion in China and the U.S. to support growth. Included in 2014 capital expenditures was approximately $31 million related to our ERP implementation. We project between $90 and $100 million of capital expenditures in 2017 and depreciation and amortization expense of approximately $70 million. We expect our spending on the manufacturing facility in Nanjing will be approximately $40 million in 2017. 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, 2016. 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. 19 In November 2016, we issued $45 million of fixed rate term notes in two tranches to two insurance companies. Principal payments commence in 2023 and 2028 and the notes mature in 2029 and 2034, respectively. The notes carry interest rates of 2.87 and 3.10, respectively. We used proceeds of the notes to pay down borrowings under our revolving credit facility. In January 2015, we issued $75 million of fixed rate term notes to an insurance company. Principal payments commence in 2020 and the notes mature in 2030. The notes carry an interest rate of 3.52 percent. We used proceeds of the notes to pay down borrowings under our revolving credit facility. At December 31, 2016, we had available borrowing capacity of $310.8 million under this facility. We believe that the 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 $323.6 million at December 31, 2016 compared with $249.0 million at December 31, 2015, as our cash flows generated in the U.S were more than offset by our share repurchase activity and our purchase of Aquasana. As a result, our leverage, as measured by the ratio of total debt to total capitalization, was 17.6 percent at the end of 2016 compared with 14.7 percent at the end of 2015. 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 2016 but made a voluntary $30 million contribution due to escalating Pension Benefit Guaranty Corporation insurance premiums. We forecast that we will not be required to make a contribution to the plan in 2017 and we do not plan to make any voluntary contributions in 2017. For further information on our pension plans, see Note 10 of the Notes to Consolidated Financial Statements. During 2016, our Board of Directors authorized the purchase of an additional 3,000,000 shares of our Common Stock. In 2016, we repurchased 3,273,109 shares at an average price of $41.30 per share and a total cost of $135.2 million. A total of 4,906,403 shares remained on the existing repurchase authorization at December 31, 2016. Depending on factors such as stock price, working capital requirements and alternative investment opportunities, such as acquisitions, we expect to spend approximately $135 million on share repurchase activity in 2017 using a 10b5-1 repurchase plan. In addition, we may opportunistically repurchase an additional $65 million of our shares in 2017. We have paid dividends for 77 consecutive years with payments increasing each of the last 25 years. We paid dividends of $0.48 per share in 2016 compared with $0.38 per share in 2015. In January 2017, we increased our dividend by 17 percent and anticipate paying dividends of $0.56 per share in 2017. Aggregate Contractual Obligations A summary of our contractual obligations as of December 31, 2016, is as follows: (dollars in millions) Contractual Obligations Long-term debt Fixed rate interest Operating leases Purchase obligations Pension and post-retirement obligations Total Total $ 323.6 38.6 37.4 150.8 66.0 $ 616.4 $ Less Than 1 year 7.2 4.6 19.5 141.4 0.9 $ 173.6 $ Payments due by period 3 - 5 1 - 2 Years Years $ 202.9 7.2 7.2 8.1 4.2 7.9 3.6 5.8 9.5 $ 38.5 8.6 $ 226.5 More than 5 years $ 106.3 18.7 5.8 - 47.0 $ 177.8 As of December 31, 2016, our liability for uncertain income tax positions was $4.2 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 Refer to Recent Accounting Pronouncements in Note 1 of Notes to Consolidated Financial Statements. 20 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. Goodwill and Indefinite-lived Intangible Assets In conformity with U.S. Generally Accepted Accounting Principles, 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 arm’s-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 annual thorough and competent valuations of goodwill and indefinite-lived intangible assets and that there has been no impairment in goodwill or indefinite-lived assets in 2016. 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, 2016, our reserve for product warranties was $140.9 million. 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 2016, 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, 2016, our reserve for product liability was $38.6 million. 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 21 assumption for the expected return on plan assets was 7.50 percent in 2016 compared to 7.75 percent in 2015. The discount rate used to determine net periodic pension costs increased to 4.40 percent in 2016 from 4.05 percent in 2015. For 2017, our expected return on plan assets is 7.50 percent and our discount rate is 4.15 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 45 to 55 percent, with the remainder allocated primarily to bond managers, private equity managers and real estate managers. Our actual asset allocation as of December 31, 2016, was 48 percent to equity managers, 37 percent to bond managers, ten percent to real estate managers, four percent to private equity managers and one percent to others. 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 5.7 percent and 9.0 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 7.50 percent expected return on plan assets for 2017 is reasonable. The discount rate assumptions used to determine future pension obligations at December 31, 2016 and 2015 were based on the AonHewitt AA Only Above Median yield curve, which was designed by AonHewitt 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. As of December 31, 2015, we changed the method we used to estimate the service and interest components of net periodic pension benefit cost for our pension plan and post-retirement benefit plan. The change was the primary reason for the $7.1 million decrease in the service and interest components of pension costs in 2016. As a result, we recognized pension income of $6.9 million in 2016 compared to $0.1 million of pension expense in 2015. Costs associated with our replacement retirement plan in 2016 were approximately $6 million, consistent with 2015. 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 which significantly decreased pension expense beginning in 2015. Lowering the expected return on plan assets by 25 basis points would increase our net pension expense for 2017 by approximately $1.9 million. Lowering the discount rate by 25 basis points would decrease our 2017 net pension expense by approximately $0.3 million. Outlook We expect our sales in China will continue to grow at a rate of approximately 15 percent in local currency terms in 2017 led by continued strong sales growth of water heaters, water treatment and air purification products. We project continued declines in the Chinese currency compared to the U.S. dollar resulting in a five percent, or $40 million, headwind in 2017 sales, compared with the average rate in 2016. We expect our sales in the U.S. to grow due to residential water heater industry growth, driven by new construction and expansion of replacement demand, as well as continued growth in sales of our boilers and water treatment products. We expect sales of Lochinvar-branded products to grow over eight percent. We expect sales of Aquasana- branded water treatment products will add an incremental $40 million of sales in 2017. We expect steel prices to continue to be volatile and to be significantly higher than our average cost in 2016. We expect our effective tax rate to be between 29.4 percent and 29.7 percent assuming the current U.S. tax system remains in place. Combining all these factors, we expect sales growth of between eight and 9.5 percent in 2017 and sales growth of between 9.5 and 11 percent measured in local currency in 2017 and earnings to be in the range of $1.98 to $2.08 per share for 2017. This does not include the potential impact of future acquisitions. 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 2016 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 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. 22 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, 2016, we had net foreign currency contracts outstanding of $102.2 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 $10.2 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, 2016, we had $189.2 million in outstanding floating-rate debt with a weighted-average interest rate of 1.5 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 $0.3 million.

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, gas tankless and electric water heaters, as well as water treatment products. Both segments primarily manufacture and market in their respective regions of the world. The North America segment also manufactures and globally markets specialty commercial water heating equipment, condensing and non-condensing boilers and water systems tanks. The Company 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. Except when otherwise indicated, amounts reflected in the financial statements or the notes thereto relate to the Company’s continuing operations. On August 22, 2011, the Company sold its Electrical Products business (EPC). Due to the sale, EPC related items have been reflected as discontinued operations in the consolidated statement of cash flows for all periods presented. 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, 2016 and 2015, due to the short maturities or frequent rate resets of these instruments. The fair value of term notes with insurance companies was approximately $133.1 million as of December 31, 2016 compared with the carrying amount of $134.4 million for the same date. The fair value of term notes with insurance companies was approximately $104.4 million as of December 31, 2015 compared with the carrying amount of $102.0 million for the same date. The fair value is estimated based on current rates offered for debt with similar maturities. Foreign currency translation. For all subsidiaries outside the U.S., with the exception of its Mexican operation and its Dutch non-operating companies, 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 are translated into U.S. dollars at year-end exchange rates, and revenues and expenses are translated at weighted-average exchange rates. The resulting translation adjustments are recorded as a separate component of stockholders’ equity. The Mexican operation and the Dutch non-operating companies use the U.S. dollar as the functional currency. Gains and losses from foreign currency transactions are included in net earnings and were not significant in 2016, 2015 or 2014. 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, 2016, the Company’s marketable securities consisted of bank time deposits with original maturities ranging from 180 days to 12 months and are primarily located at investment grade rated banks in China. Inventory valuation. Inventories are carried at lower of cost or market. Cost is determined on the last-in, first-out (LIFO) method for a majority of the Company’s domestic inventories, which comprise 61 percent and 66 percent of the Company’s total inventory at December 31, 2016 and 2015, respectively. Inventories of foreign subsidiaries, the remaining domestic inventories and supplies are 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. 29 1. Organization and Significant Accounting Policies (continued) 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 three to 25 years. Impairment of long-lived and amortizable intangible assets. Property, plant and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset or group of assets, a loss is recognized for the difference between the fair value and carrying value of the asset or group of assets. Such analyses 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. 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 2016 and 2015: Years ended December 31 (dollars in millions) Balance at beginning of year Expense Claims settled Balance at end of year 2016 $ 139.3 43.2 (41.6) $ 140.9 2015 $ 136.2 50.3 (47.2) $ 139.3 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 (AOCI), depending on whether the derivative is designated as part of a hedge transaction and if so, the type of hedge transaction. See Note 11, “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): Fair Value Measurement Using Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Total assets measured at fair value December 31, 2016 December 31, 2015 $ 424.5 - $ 424.5 $ 323.9 (0.3) $ 323.6 There were no changes in the valuation techniques used to measure fair values on a recurring basis. 30 1. Organization and Significant Accounting Policies (continued) Revenue recognition. The Company recognizes revenue upon transfer of title, which occurs upon shipment of the product to the customer except for certain export sales where transfer of title occurs when the product reaches the customer destination. Contracts and customer purchase orders are used to determine the existence of a sales arrangement. Shipping documents are used to verify shipment. The Company assesses whether the selling price is fixed or determinable based upon the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. The Company assesses collectability based on the creditworthiness of the customer as determined by credit checks and analysis, as well as the customer’s payment history. The allowance for doubtful accounts was $6.3 million and $6.0 million at December 31, 2016 and 2015, respectively. Reserves for customer returns for defective product are based on historical experience with similar types of sales. Accruals for rebates and incentives are based on pricing agreements and are tied to sales volume. Changes in such accruals may be required if future returns differ from historical experience or if actual sales volume differs from estimated sales volume. Rebates and incentives are recognized as a reduction of sales. Shipping and handling costs billed to customers are included in net sales and the related costs are included in cost of products sold. Advertising. The majority of advertising costs are charged to operations as incurred and amounted to $113.9 million, $102.2 million and $94.0 million during 2016, 2015 and 2014, respectively. Included in total advertising costs are expenses associated with store displays for water heater and water treatment products in China that are amortized over 12 to 24 months which totaled $37.0 million, $27.4 million and $22.6 million during 2016, 2015 and 2014, respectively. Research and development. Research and development costs are charged to operations as incurred and amounted to $80.1 million, $73.7 million and $67.9 million during 2016, 2015 and 2014, 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. The Company adopted amended ASC 718 Compensation – Stock Compensation as of January 1, 2016. Refer to the Recent Accounting Pronouncements section later in this footnote for additional information on the adoption of this pronouncement. As required under amended ASC 718, in the year ended December 31, 2016, the Company recognized $5.9 million of discrete income tax benefits on settled stock based compensation awards. As required under previous guidance, in the year ended December 31, 2015, the Company recognized $10.4 million of excess tax deductions as cash flows provided by financing activities. 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. 31 1. Organization and Significant Accounting Policies (continued) 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: Denominator for basic earnings per share - weighted-average shares outstanding Effect of dilutive stock options, restricted stock and share units Denominator for diluted earnings per share 2016 2015 2014 174,712,683 2,112,597 176,825,280 177,622,280 1,386,900 179,009,180 180,587,008 1,386,954 181,973,962 On April 11, 2016, the Company’s stockholders approved a proposal to increase the Company’s authorized shares of Common Stock and on September 7, 2016, the Company’s Board of Directors declared a two-for-one stock split of the Company’s Class A Common Stock and Common Stock (including treasury shares) in the form of a 100 percent stock dividend to stockholders of record on September 21, 2016 and payable on October 5, 2016. All references in the financial statements and footnotes to the number of shares outstanding, price per share, per share amounts and stock based compensation data have been recast to reflect the stock split for all periods presented. Reclassifications. Certain amounts from prior years have been reclassified to conform with current year presentation. Recent Accounting Pronouncements In October 2016, the Financial Accounting Standards Board (FASB) amended ASC 740, Income Taxes (issued under Accounting Standards Update (ASU) 2016-16). This amendment requires that the income tax consequences of an intra-entity transfer of an asset other than inventory be recognized when the transfer occurs. The amendment is effective for the Company beginning January 1, 2018. This amendment is required to be applied on a modified retrospective basis through a cumulative- effect adjustment directly to retained earnings. The Company does not expect the adoption of amended ASC 740 will have a material impact on the Company’s consolidated financial condition, results of operations or cash flows. In August 2016, the FASB amended ASC 230, Statement of Cash Flows (issued under ASU 2016-15, “Clarification of Certain Cash Receipts and Cash Payments”). This amendment clarifies reporting for contingent consideration payments made after a business combination depending on how soon after the acquisition the payments are made. The amendment requires adoption for periods beginning January 1, 2018 and permits early adoption. The Company does not expect the adoption of ASU 2016- 15 will have a material impact on its consolidated statement of cash flows. In March 2016, the FASB amended ASC 718, Compensation - Stock Compensation (issued under ASU 2016-09). This amendment simplified several aspects of the accounting for share-based payment transactions. The Company adopted this amendment effective January 1, 2016. The amendment requires the benefits or deficiencies of tax deductions in excess of or less than the recognized compensation cost to be recorded as income tax benefits or expense in the Consolidated Statement of Earnings in the periods in which they occur. The amendment also eliminated previous guidance that required unrecognized future excess income tax benefits to be considered used to repurchase shares in the calculation of diluted shares which resulted in lower diluted shares outstanding than the calculation under the amendment. The Company applied this guidance prospectively. As such, in the year ended December 31, 2016, the Company recognized $5.9 million of discrete income tax benefits associated with excess tax benefits on settled stock based compensation awards and the Company’s diluted shares outstanding for the year ended December 31, 2016 increased as compared to the way it was calculated under previous guidance. The amendment also required that cash paid by an employer to a taxing authority when shares are directly withheld for employee income tax withholding purposes be classified as financing activities in the consolidated statement of cash flows. As required, the Company applied this guidance retrospectively in the presentation of the consolidated statement of cash flows for the period beginning January 1, 2014 and, as a result, reclassified $7.3 million and $0.1 million of cash used by operating activities to cash used by financing activities for the years ended December 31, 2015 and 2014, respectively. 32 1. Organization and Significant Accounting Policies (continued) 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 currently classified as operating leases. This amendment is effective for periods beginning January 1, 2019 and early adoption is permitted. The Company is in the process of determining whether the adoption of ASU 2016-02 will have a material impact on its consolidated balance sheets, consolidated statement of earnings or consolidated statement of cash flows. In November 2015, the FASB amended ASC 740, Income Taxes (issued under ASU 2015-17). This amendment required that deferred tax assets and liabilities be classified as noncurrent on the balance sheet. The amendment was effective for periods beginning January 1, 2016 and allowed either prospective adoption or retrospective adoption. The Company adopted ASU 2015-17 retrospectively and, as a result, classified all deferred tax assets and liabilities as non-current on the Company’s consolidated balance sheets for all periods presented. Current deferred taxes of $39.9 million as of December 31, 2015 were reclassified to non-current deferred taxes on the Company’s consolidated balance sheet. In July 2015, the FASB amended ASC 330, Inventory (issued under ASU 2015-11, “Simplifying the Measurement of Inventory”). This amendment requires inventory that is recorded using the first-in, first-out method to be measured at the lower of cost or net realizable value. ASU 2015-11 is effective prospectively for the Company beginning January 1, 2017. The Company does not expect the adoption of ASU 2015-11 to have a significant impact on its consolidated balance sheets, consolidated statement of earnings or consolidated statement of cash flows. In May 2014, the FASB issued ASC 606-10, Revenue from Contracts with Customers (issued under ASU 2014-09). ASC 606- 10 will replace all existing revenue recognition guidance when effective. In July 2015, the FASB approved a one year deferral of the effective date to periods beginning January 1, 2018. The Company expects to utilize the full retrospective method of adoption beginning January 1, 2018 and does not expect the adoption of ASC 606-10 to have a material impact on its consolidated balance sheets, consolidated statement of earnings or consolidated statement of cash flows. 2. Acquisitions On August 8, 2016, the Company acquired 100 percent of the shares of Aquasana, Inc. (Aquasana), a Texas-based water treatment company. With the addition of Aquasana, the Company entered the U.S. water treatment market. Aquasana is included in the Company’s North America segment for reporting purposes. The Company paid an aggregate cash purchase price of $85.1 million, net of $1.9 million of cash acquired. In addition, the Company incurred acquisition-related costs of approximately $1.2 million and recorded contingent consideration of $1.9 million, the fair value of the contingent payment due to the former owners of Aquasana if certain performance targets are met. The following table summarizes the preliminary allocation of fair value of the assets acquired and liabilities assumed at the date of acquisition. The Company is awaiting final valuations to support the acquired intangible assets as well as finalizing the accounting for acquired liabilities. The $30.0 million of acquired intangible assets was comprised of $21.5 million of trade names that are not subject to amortization, $8.3 million of customer lists which will be amortized over ten years and $0.2 million of patents which will be amortized over five years. August 8, 2016 (dollars in millions) Current assets, net of cash acquired Property, plant and equipment Intangible assets Goodwill Total assets acquired Current liabilities Long-term liabilities Total liabilities assumed Net assets acquired $ 7.3 2.7 30.0 60.4 100.4 (7.1) (8.2) (15.3) 85.1 $ 33 2. Acquisitions (continued) The acquisition was accounted for using the purchase method of accounting, and accordingly, the results of operations have been included in the Company’s financial statements from August 8, 2016, the date of acquisition. Revenues and pre-tax losses associated with Aquasana included in the consolidated statement of earnings totaled $18.4 million and $(0.1) million, respectively, which included $1.1 million of operating earnings less $1.2 million of acquisition-related costs incurred by the Company resulting from the acquisition. On August 26, 2016, the Company acquired certain assets, primarily inventory, and assumed a lease of a small electric water heater manufacturer serving the North America market. The Company paid $5.7 million for the assets. Under the purchase agreement, the Company agreed to make additional contingent payments for the acquired assets if certain conditions are met over the next ten years. As of December 31, 2016, the Company estimated the fair value of the contingent payments at $5.2 million and a liability for the contingent consideration was accrued. 3.

Debt and Lease Commitments (continued) In December 2016, the Company completed a $500 million multi-year multi-currency revolving credit agreement with a group of nine banks, which expires on December 15, 2021. The facility has an accordion provision which allows it to be increased up to $700 million if certain conditions (including lender approval) are satisfied. Borrowings under the Company’s bank credit lines and commercial paper borrowings are supported by the revolving credit agreement. As a result of the long-term nature of this facility, the commercial paper and credit line borrowings are classified as long-term debt at December 31, 2016 and 2015. At its option, the Company either maintains cash balances or pays fees for bank credit and services. On November 28, 2016, the Company issued $45 million in term notes in two tranches to two insurance companies. Principal payments commence in 2023 and the notes mature in 2029 and 2034. The notes have interest rates of 2.87 percent and 3.10 percent. Proceeds of the notes were used to pay down borrowings under the Company’s revolving credit facility. On January 15, 2015, the Company issued $75 million in term notes to an insurance company. Principle payments commence in 2020 and the notes mature in 2030. The notes have an interest rate of 3.52 percent. Proceeds of the notes were used to pay down borrowings under the Company’s revolving credit facility. Scheduled maturities of long-term debt within each of the five years subsequent to December 31, 2016 are as follows: Years ending December 31 (dollars in millions) 2017 2018 2019 2020 2021 Amount 7.2 $ 7.2 - 6.8 196.1 Future minimum payments under non-cancelable operating leases relating mostly to office, manufacturing and warehouse facilities total $37.4 million and are due as follows: Years ending December 31 (dollars in millions) 2017 2018 2019 2020 2021 Thereafter Amount $ 19.5 4.5 3.4 2.3 1.9 5.8 Rent expense, including payments under operating leases, was $29.8 million, $28.8 million and $24.3 million in 2016, 2015 and 2014, respectively. Interest paid by the Company was $7.2 million, $6.4 million and $5.8 million in 2016, 2015 and 2014, respectively. The Company capitalized interest expense of $0.2 million, $0.2 million and $0.4 million in 2016, 2015 and 2014, respectively. 8. Stockholders’ Equity The Company’s authorized capital consists of three million shares of Preferred Stock $1 par value, 27 million shares of Class A Common Stock $5 par value, and 240 million shares of Common Stock $1 par value. The Common Stock has equal dividend rights with Class A Common Stock and is entitled, as a class, to elect one-third of the Board of Directors and has 1/10th vote per share on all other matters. Class A Common Stock is convertible to Common Stock on a one for one basis. There were 60,045 shares during 2016, 67,544 shares during 2015 and 136,092 shares during 2014, of Class A Common Stock converted into Common Stock. Regular dividends paid on the A. O. Smith Corporation Class A Common Stock and Common Stock amounted to $0.48, $0.38 and $0.30 per share in 2016, 2015 and 2014, respectively. The Company completed a two-for-one stock split on October 5, 2016. Amounts have been adjusted to reflect the stock split. 36 8. Stockholders’ Equity (continued) In 2014, the Company’s Board of Directors authorized the purchase of an additional 7,000,000 shares of the Company’s Common Stock. In 2015, the Company’s Board of Directors authorized the purchase of an additional 4,000,000 shares of the Company’s Common Stock. In 2016, the Company’s Board of Directors authorized the purchase of an additional 3,000,000 shares of the Company’s Common Stock. Under the share repurchase program, the Company’s Common Stock may be purchased through a combination of a 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 purchase will depend on a number of factors, including share price, trading volume and general market conditions, as well as on working capital requirements, general business conditions and other factors, including alternative investment opportunities. The share repurchase authorization remains effective until terminated by the Board of Directors which may occur at any time, subject to the parameters of any Rule 10b5-1 automatic trading plan that the Company may then have in effect. In 2016, the Company purchased 3,273,109 shares at a total cost of $135.2 million. As of December 31, 2016, there were 4,906,403 shares remaining on the existing repurchase authorization. In 2015, the Company purchased 3,816,474 shares at a cost of $128.1 million. In 2014, the Company purchased 4,309,566 shares at a cost of $103.8 million. At December 31, 2016, a total of 130,380 and 17,135,628 shares of Class A Common Stock and Common Stock, respectively, were held as treasury stock. At December 31, 2015, a total of 130,380 and 14,680,346 shares of Class A Common Stock and Common Stock, respectively, were held as treasury stock. Accumulated other comprehensive loss is as follows: December 31 (dollars in millions) Cumulative foreign currency translation adjustments Unrealized net gain on cash flow derivative instruments less related income tax provision of $(0.1) in 2016 and $(0.8) in 2015 Pension liability less related income tax benefit of $183.4 in 2016 and $177.7 in 2015 2016 $ (79.2) 0.2 (284.2) $(363.2) 2015 $ (39.4) 1.2 (275.2) $(313.4) 37 8.

See Note 10 - Pensions and Other Post-retirement Benefits for additional details 9. 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 shareholders in 2002. The number of shares available for granting of options or share units at December 31, 2016, was 3,275,459. Upon stock option exercise or share unit vesting, shares are issued from treasury stock. Total stock based compensation expense recognized in 2016, 2015 and 2014 was $9.4 million, $8.8 million and $10.8 million, respectively. 38 9. Stock Based Compensation (continued) Stock options The stock options granted in 2016, 2015 and 2014 have three year pro rata vesting from the dates of grant. Stock options are issued at exercise prices equal to the fair value of Common Stock on the date of grant. For active employees, all options granted in 2016, 2015 and 2014 expire ten years after date of grant. Stock option compensation recognized in 2016, 2015 and 2014 was $4.5 million, $4.0 million and $4.9 million, respectively. Included in the stock option expense recognized in 2016, 2015 and 2014 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 option shares, all of which are Common Stock, were as follows: Weighted-Avg. Per Share Exercise Price Years Ended December 31 2015 2016 2014 (dollars in millions) Aggregate Intrinsic Value Outstanding at beginning of year $ 18.03 2,653,558 3,154,006 2,881,246 Granted 2016--$31.49 to $46.93 per share 2015--$23.24 to $25.34 per share 2014--$17.46 to $26.47 per share Exercised 2016--$4.75 to $30.77 per share 2015--$4.10 to $17.46 per share 2014--$4.10 to $11.50 per share Forfeited 2016--$23.24 to $46.93 per share 2015--$17.46 to $23.24 per share 2014--$11.50 to $17.46 per share Outstanding at end of year (2016--$4.75 to $46.93 per share) 553,370 484,990 (531,933) (978,208) 597,500 (316,502) $ 7.5 10.2 2.6 (10,662) (7,230) (8,238) 21.69 2,664,333 2,653,558 3,154,006 Exercisable at end of year 16.12 1,602,651 1,544,186 1,865,278 The aggregate intrinsic value for the outstanding and exercisable options as of December 31, 2016 is $68.5 million and $50.1 million, respectively. The average remaining contractual life for outstanding and exercisable options is seven years and six years, respectively. The following table summarizes weighted-average information by range of exercise prices for stock options outstanding and exercisable at December 31, 2016: Range of Exercise Prices $4.75 to $11.50 $17.46 to $25.34 $26.47 to $46.93 Options Outstanding at December 31, 2016 683,434 954,074 1,026,825 2,664,333 Weighted- Average Exercise Price $ 8.31 20.76 31.36 Options Exercisable at December 31, 2016 683,434 759,014 160,203 1,602,651 Weighted- Average Exercise Price $ 8.31 20.12 30.52 Weighted- Average Remaining Contractual Life 4 years 7 years 9 years 39 9. Stock Based Compensation (continued) The weighted-average fair value per option at the date of grant during 2016, 2015 and 2014, using the Black-Scholes option- pricing model, was $8.03, $8.59 and $8.28, respectively. Assumptions were as follows: Expected life (years) Risk-free interest rate Dividend yield Expected volatility 2016 5.8 1.7% 1.3% 27.7% 2015 5.9 2.0% 1.0% 29.3% 2014 6.0 2.7% 1.1% 36.6% The expected life of options for purposes of these models is based on historical exercise behaviors. 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 on Common Stock. The expected volatility for purposes of these models is based on the historical volatility of the Common Stock. Stock Appreciations Rights (SARs) Certain non-U.S.-based employees are granted SARs. Each SAR award grants the employee the right to receive cash equal to the excess of the share price of the Common Stock on the date that a participant exercises such right over the grant date price of the stock. SARs granted have three year pro rata vesting from the date of grant. SARs were issued at exercise prices equal to the fair value of Common Stock on the date of grant and expire ten years from the date of grant. Compensation expense for SARs is remeasured at each reporting period based on the estimated fair value on the date of grant using the Black-Scholes option-pricing model, using assumptions similar to stock option awards. SARs are subsequently remeasured at each interim reporting period based on a revised Black-Scholes value. No SARs were granted in 2016. As of December 31, 2016, there were 24,940 SARs outstanding and 8,320 were exercisable. In 2015, the Company granted 26,230 cash-settled SARs and no SARs were exercisable. Stock based compensation expense attributable to SARS was minimal in 2016 and 2015. Restricted stock and share units Participants may also be awarded shares of restricted stock or share units under the Plan. The Company granted 160,465, 152,192 and 221,382 share units under the plan in 2016, 2015 and 2014, respectively. The share units were valued at $5.2 million, $4.7 million and $5.1 million at the date of issuance in 2016, 2015 and 2014, respectively, and will be recognized as compensation expense ratably over the three-year vesting period; however, included in share based compensation is expense associated with the accelerated vesting of share unit awards for certain employees who either are retirement eligible or become retirement eligible during the vesting period. Compensation expense of $4.9 million, $4.8 million and $5.9 million was recognized in 2016, 2015 and 2014, respectively. Certain non-U.S.-based employees receive the cash value of vested shares at the vesting date in lieu of shares. A summary of share unit activity under the plan is as follows: Outstanding at January 1, 2016 Granted Vested Forfeited/cancelled Outstanding at December 31, 2016 Number of Units Weighted-Average Grant Date Value 658,326 160,465 (268,306) (6,430) 544,055 $ 22.15 32.21 17.39 31.81 27.35 Total compensation expense for share units not yet recognized is $2.3 million at December 31, 2016. The weighted average period over which the expense is expected to be recognized is 14 months. 40 10. 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. Beginning in 2015, an additional Company contribution is being 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. As of December 31, 2015, the Company changed the method used to estimate the service and interest components of net periodic benefit cost for its pension plan and its post-retirement benefit plan. This change compared to the previous method resulted in a $7.1 million decrease in the service and interest components for pension cost in 2016. Historically, the Company estimated the service and interest cost components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. The Company has elected to utilize an approach that discounts the individual expected cash flows underlying the service cost and interest cost using the applicable spot rates derived from the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. This change was made to provide a more precise measurement of service and interest costs by improving the correlation between the projected benefit cash flows to the corresponding spot yield curve rates. This change did not affect the measurement of the total benefit obligations but reduced the service and interest cost for the pension plan. The Company accounted for this change as a change in accounting estimate that is inseparable from a change in accounting principle and accordingly accounted for it prospectively beginning January 1, 2016. 41 10. Pension and Other Post-retirement Benefits (continued) Obligations and Funded Status Pension and Post-Retirement Disclosure Information under ASC 715 The following tables present the changes in benefit obligations, plan assets and funded status for domestic pension and post- retirement plans and the components of net periodic benefit costs.

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 2017 are $0.1 million and $(0.4) 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. Beginning in 2015 the amortization occurs over the average remaining life expectancy of participants expected to receive benefits under the plan as permitted under ASC 715. The 2016 and 2015 after tax adjustments for additional minimum pension liability resulted in other comprehensive (loss) gain of $(9.0) million and $1.0 million, respectively. Actuarial assumptions used to determine benefit obligations at December 31 are as follows: Discount rate Average salary increases Pension Benefits 2016 4.15% 4.00% 2015 4.40% 4.00% Post-retirement Benefits 2015 2016 4.55% 4.33% 4.00% 4.00% Actuarial assumptions used to determine net periodic benefit cost for the year ended December 31 are as follows: Years ended December 31 Discount rate Expected long-term return on plan assets Rate of compensation increase Pension Benefits 2015 4.05% 7.75% 4.00% 2014 4.85% 7.75% 4.00% 2016 4.40% 7.50% 4.00% 43 Post-retirement Benefits 2015 4.00% n/a 4.00% 2014 4.70% n/a 4.00% 2016 4.55% n/a 4.00% 10. Pension and Other Post-retirement Benefits (continued) 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 5.7 percent and 9.0 percent, respectively. Assumed health care cost trend rates Assumed health care cost trend rates as of December 31 are as follows: Health care cost trend rate assumed for next year Rate to which the cost trend rate is assumed to decline (the ultimate trend rate) Year that the rate reaches the ultimate trend rate 2016 6.50 % 5.00 % 2021 2015 6.75 % 5.00 % 2021 A one-percentage-point change in the assumed health care cost trend rates would not result in a material impact on the Company’s consolidated financial statements. Plan Assets The Company’s pension plan weighted asset allocations as of December 31 by asset category are as follows: Asset Category Equity securities Debt securities Real estate Private equity Other 2016 48 % 37 10 4 1 100 % 2015 47 % 39 9 5 - 100 % 44 10.

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 45 to 55 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, 2016. Cash Flows The Company was not required to make a contribution in 2016 but elected to make a $30 million voluntary contribution. The Company is not required to make a contribution in 2017. Estimated Future Payments The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid: Years ending December 31 (dollars in millions) 2017 2018 2019 2020 2021 2022 – 2026 Pension Benefits $ 60.2 67.6 60.1 66.4 59.2 284.4 Post-retirement Benefits $ 0.4 0.4 0.4 0.4 0.4 2.1 46 11. Derivative instruments ASC 815 Derivatives and Hedging, as amended, requires that all derivative instruments be recorded on the balance sheet at fair value and establishes criteria for designation and effectiveness of the hedging relationships. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as a part of a hedging relationship and, further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, the Company must designate the hedging instrument, based upon the exposure hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation. 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), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive loss, net of tax, and is 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. The amount by which the cumulative change in the value of the hedge more than offsets the cumulative change in the value of the hedged item (i.e., the ineffective portion) is recorded in earnings, net of tax, in the period the ineffectiveness occurs. 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. 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 amounts in accumulated other comprehensive loss for cash flow hedges will be reclassified into earnings no later than December 31, 2018. 47 11. Derivative instruments (continued) The following table summarizes, by currency, the contractual amounts of the Company’s foreign currency forward contracts: December 31 (dollars in millions) 2016 2015 British pound Canadian dollar Euro Mexican peso Total Commodity Futures Contracts Buy $ - - 25.4 16.9 $ 42.3 Sell $ 1.2 56.9 1.8 - $ 59.9 Buy $ - - 21.3 12.7 $ 34.0 Sell $ 0.9 43.2 1.7 - $ 45.8 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 copper and steel, with the objective of minimizing changes in cost due to market price fluctuations. The hedging strategy for achieving this objective is to purchase commodities futures contracts on the open market of the London Metals Exchange (LME) or over the counter contracts based on the LME for copper. Steel futures contracts are purchased on the New York Metals Exchange (NYMEX). With NYMEX, the Company is required to make cash deposits on unrealized losses on steel derivative contracts. The after-tax gains and losses of the effective portion of the contracts as of December 31, 2016 were recorded in accumulated other comprehensive loss and will be reclassified into cost of products sold in the periods in which the underlying transactions are recorded in earnings. The after-tax gains and losses on the effective portion of the contracts will be reclassified within one year. Contractual amounts of the Company’s commodities futures contracts were immaterial as of December 31, 2016. The impact of derivative contracts on the Company’s financial statements is as follows: Fair value of derivative instruments designated as hedging instruments under ASC 815: December 31 (dollars in millions) Foreign currency contracts Commodities contracts Total derivatives designated as hedging instruments Balance Sheet Location Other current assets Accrued liabilities Other current assets Accrued liabilities Fair Value 2016 $ 1.9 (2.0) 0.8 (0.3) $ 0.4 2015 $ 3.6 (1.3) - (0.3) $ 2.0 48 11.

Income Taxes The components of the provision (benefit) for income taxes consisted of the following: Years ended December 31 (dollars in millions) Current: Federal State International Deferred: Federal State International 2016 $ 71.6 14.5 34.9 11.0 5.2 (1.2) $ 136.0 2015 $ 82.9 13.9 23.6 (4.2) 2.2 1.2 $ 119.6 The provision for income taxes differs from the U.S. federal statutory rate due to the following items: Years ended December 31 Provision at U.S. federal statutory rate State taxes, net of federal benefit International income tax rate differential - China International income tax rate differential - other U.S. manufacturing credit Research tax credits Excess tax benefit on stock compensation Other 2016 35.0 % 2.8 (6.2) 0.3 (1.5) (0.3) (1.1) 0.4 29.4 % 2015 35.0 % 2.6 (6.8) 0.2 (1.3) (0.3) - 0.3 29.7 % 2014 $ 48.7 10.4 22.4 (5.2) (0.2) 2.8 $ 78.9 2014 35.0 % 2.3 (8.2) 0.4 (2.1) (0.4) - 0.5 27.5 % Components of earnings before income taxes were as follows: Years ended December 31 (dollars in millions) U.S. International 2016 $ 300.9 161.6 $ 462.5 2015 $ 255.7 146.8 $ 402.5 2014 $ 150.6 136.1 $ 286.7 49 12. Income Taxes (continued) Total income taxes paid by the Company amounted to $117.4 million, $97.5 million, and $88.9 million in 2016, 2015 and 2014, respectively. As of December 31, 2016, the Company has $42.3 million accrued for its estimate of the tax costs due upon repatriation of undistributed foreign earnings it considers to be not permanently reinvested. At December 31, 2016, the Company had undistributed foreign earnings of $982.2 million, of which $828.2 million are considered permanently reinvested. No U.S. income tax provision or foreign withholding tax provisions have been made on foreign earnings that remain permanently reinvested. The Company considers permanently reinvested earnings outside the U.S. on the basis of estimates that future domestic cash generation will be sufficient to meet future domestic cash needs and its specific plans for reinvestment of foreign subsidiary earnings. In addition, no provision or benefit for U.S. income taxes has been made on foreign currency translation gains or losses. As of December 31, 2016, $751.7 million of cash and cash equivalents and marketable securities were held by our foreign subsidiaries. The tax effects of temporary differences of assets and liabilities between income tax and financial reporting are as follows: December 31 (dollars in millions) Employee benefits Product liability and warranties Inventories Accounts receivable Property, plant and equipment Intangibles Environmental liabilities Undistributed foreign earnings Tax loss and credit carryovers All other Valuation allowance Net asset 2016 2015 Assets $ 67.5 67.1 - 14.9 - - 2.9 - 18.2 4.3 (13.1) $ 161.8 $ 4.4 Liabilities $ - - 3.4 - 34.3 77.4 - 42.3 - - - $ 157.4 Assets $ 75.0 66.8 - 13.0 - - 2.7 - 14.6 3.4 (11.0) $ 164.5 $ 21.0 $ Liabilities - - 4.4 - 36.9 54.3 - 47.9 - - - $ 143.5 In November 2015, the FASB amended ASC 740, Income Taxes (issued under ASU 2015-17). This amendment required that deferred tax assets and liabilities be classified as non-current in the balance sheet. The Company adopted ASU 2015-17 on January 1, 2017 retrospectively and, as a result, has classified all deferred tax assets and liabilities as non-current in the Company’s consolidated balance sheets for all periods presented. Current deferred taxes of $39.9 million as of December 31, 2015 were reclassified to non-current deferred taxes in the Company’s consolidated balance sheet. The Company believes it is more likely than not that it will realize its deferred tax assets through the reduction of future taxable income. Significant factors the Company considered in determining the probability of the realization of the deferred tax assets include historical operating results and expected future earnings. A reconciliation of the beginning and ending amounts of tax loss carryovers, credit carryovers and valuation allowances is as follows: December 31 (dollars in millions) Beginning balance Additions Reductions Ending balance Net Operating Losses and Tax Credits 2016 $ 14.6 3.7 (0.1) $ 18.2 2015 $ 14.9 1.4 (1.7) $ 14.6 50 Valuation Allowances 2015 $ 9.8 1.4 (0.2) $ 11.0 2016 $ 11.0 2.1 - $ 13.1 12. Income Taxes (continued) The Company has foreign net operating loss carryovers that expire in 2017 through 2024 and state and local net operating loss carryovers that expire between 2017 and 2033. A reconciliation of the beginning and ending amount of unrecognized benefits is as follows: (Dollars in millions) Balance at January 1 Additions for tax positions of prior years Balance at December 31 2016 $ 2.6 1.6 $ 4.2 2015 $ 1.2 1.4 $ 2.6 The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $0.6 million. The Company recognizes potential interest and penalties related to unrecognized tax benefits as a component of income tax expense. At December 31, 2016, there was an immaterial amount of interest and penalties accrued. It is anticipated there will be no decrease in the total amount of unrecognized tax benefits in 2017. The Company’s U.S. federal income tax returns for 2014- 2016 are subject to audit. The Company is subject to state and local income tax audits for tax years 2001-2016. The Company is subject to non-U.S. income tax examinations for years 2008-2016. 13. Commitments and 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. 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, 2016 and 2015, 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. 14. Operations by Segment 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, gas tankless and electric water heaters as well as water treatment products. Both segments primarily manufacture and market in their respective regions of the world. The North America segment also manufactures and globally markets specialty commercial water heating equipment, condensing and non-condensing boilers and water system tanks. The Company also manufactures and markets in-home air purification products in China. 51 14. Operations by Segment (continued) The accounting policies of the reportable segments are the same as those described in the “Summary of Significant Accounting Policies” outlined in Note 1. Operating earnings, defined by the Company as earnings before interest, taxes, general corporate and corporate research and development expenses, were used to measure the performance of the segments. 2016 Net Sales 2015 $ 1,743.2 $ 1,703.0 $ 1,621.7 768.3 (34.0) $ 2,685.9 $ 2,536.5 $ 2,356.0 965.6 (22.9) 866.1 (32.6) 2014 Years ended December 31 (dollars in millions) North America Rest of World Inter-segment Total segments – sales, operating earnings Corporate expenses Interest expense Earnings before income taxes Provision for income taxes Earnings from continuing operations 2016 $ 385.9 129.1 - $515.0 Earnings 2015 $ 339.9 113.0 - $452.9 2014 $ 238.7 106.7 (0.1) $ 345.3 (45.2) (7.3) (43.0) (7.4) (52.9) (5.7) 462.5 (136.0) 402.5 (119.6) 286.7 (78.9) $ 326.5 $ 282.9 $ 207.8 In 2016, sales to the North America segment’s two largest customers were $311.5 million and $280.8 million which represented 12 percent and 11 percent of the Company’s net sales, respectively. In 2015, sales to the North America segment’s two largest customers were $301.7 million and $287.0 million which represented 12 percent and 11 percent of the Company’s net sales, respectively. In 2014, sales to the North America segment’s two largest customers were $296.5 million and $237.2 million which represented 13 percent and ten percent of the Company’s net sales, respectively.

ITEM 9 – CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A – CONTROLS AND PROCEDURES 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 such term is defined in Rules 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 such evaluations, 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 such term is 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 Aquasana, Inc., which was acquired in 2016 and constituted 3.5 percent and 5.8 percent of total assets and net assets, respectively, as of December 31, 2016 and 0.8 percent and 0.2 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, 2016, 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, 2016 as stated in their report which is included herein. 53 Changes in Internal Control Over Financial Reporting In 2016, we continued the implementation of a new global enterprise resource planning system. This multi-year initiative is being conducted in phases and includes modifications to the design and operation of controls over financial reporting. We are testing internal controls over financial reporting for design effectiveness prior to the implementation of each phase, and we have monitoring controls in place over the implementation of these changes. Except as described above, there have been no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities and Exchange Act) during the year ended December 31, 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. ITEM 9B - OTHER INFORMATION None 54 Report of Independent Registered Public Accounting Firm The Board of Directors and Stockholders A. O. Smith Corporation We have audited A. O. Smith Corporation’s internal control over financial reporting as of December 31, 2016, 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). A. O. Smith Corporation’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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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. 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. 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 Aquasana, Inc., which is included in the 2016 consolidated financial statements of A. O.

We repurchased more than three million shares of company stock at an approximate cost of $135 million. In January, we announced a 17 percent increase in the company’s quarterly cash dividend, the 12th consecutive year in which we raised the dividend. In August, the company entered the North American water treatment market with the acquisition of Aquasana, Inc., of Austin, Texas. Aquasana manufactures an extensive line of premium water treatment products, ranging from point- of-entry systems for the home and on-the-go products such as portable filter bottles. Aquasana markets its products directly to consumers, with 80 percent of sales coming from its web site and call center located just outside Fort Worth. We believe this new business presents us with numerous opportunities, as consumers are becoming more aware of water quality issues throughout the U.S. and are seeking healthier alternatives for their families. We also anticipate revenue synergies as we take Aquasana products to our existing businesses in China and India and introduce our patented reverse osmosis products to U.S. consumers. Growth Strategy: Organic Growth China: Lochinvar brands: NA water heaters & other: 32% of sales growing 15% 4.8% 11% of sales growing 8% .9% 57% of sales growing 4% 2.3% Total annual sales growth 8.0% The North American segment unit reported sales increased to $1.74 billion, a 14 percent increase in operating profits to $385.9 million and an impressive 200 basis point increase in operating margin. Higher volumes of boilers and commercial water heaters contributed to the sales increase, and the team in Canada did an excellent job of growing the business in spite of the challenges coming from the strong U.S. dollar. Although sales of Lochinvar-branded products did not increase at the pace we expected, we did add share in the important high-efficiency condensing boiler market. With a large installed base of older, inefficient cast iron boilers in North America, we believe there is room for further growth in this market segment. After a number of years focused on meeting new government efficiency standards, we are now turning our sights to new product development, and 2017 promises to be a busy year in both the commercial and residential segments. Chief among these new products are: • The Cyclone® series 300 with an integrated touchscreen and remote monitoring capability; • The Lochinvar Noble combi boiler that allows us to enter a portion of the residential boiler market in which we were not participating; • The ProLine® series of commercial-grade residential water heaters. These units feature a number of commercial quality components developed by APCOM and, in some cases, come with an eight-year warranty; and • A full suite of electric tankless water heaters, a line of products we have not offered in the past. The Rest of World segment experienced a sales increase of 11 percent to $965.6 million, operating earnings of $129.1 million, a 14 percent increase, and operating margins of 13.4 percent. Our operations in China continue to outperform the Chinese economy, as we take advantage of the well-known A. O. Smith brand in that market. Sales of gas tankless water heaters increased more than 20 percent, while heat pump and other renewable water heater technologies also grew at double-digit rates (all measured in local currency). A sizable percentage of our sales are coming from the e-commerce channel, with revenues of nearly $200 million last year. Water treatment products continue to grow at a fast pace, as sales increased nearly 40 percent in the local currency over the prior year. In addition, sales of our air purification line of products nearly tripled over the prior year as Chinese consumers became aware of the air pollution problems in large parts of the country. To meet the demand for water treatment and air purification products, we began construction of a new 700,000 square foot plant in Nanjing during the fourth quarter of 2016. The new plant, which also will include new product engineering and quality labs, will begin production early next year. Looking ahead, we expect to achieve our eight percent revenue growth model in 2017 as we benefit from an incremental $40 million in Aquasana sales, improved residential water heater sales in the U.S. and continued commercial water heater and boiler sales increases. China’s growth will continue to outpace that country’s economy as we will benefit from household formation, market share gains and higher average selling prices in the water heater market, and the water treatment and air purification product lines once again experience double-digit growth. This outlook is tempered by the likelihood of higher material costs—most notably steel—and the U.S. dollar’s impact on Chinese, Canadian, and other foreign currencies. Nonetheless, I have confidence in the A. O. Smith team and its ability to meet these challenges—as they have in the past—and succeed. Everyone throughout our organization is focused on the Fundamentals for Success, the foundation for everything we do as a company: • Live our values which define who we are, how we do business, and the relationship we have with our customers, suppliers, and the communities in which we do business; • Relentlessly take care of the customer, obsessively understand what our customers want and need in order for them to succeed—and then deliver on those needs; • Invest in innovation in order to provide our customers with market-leading products and solutions; and • Invest in our people by giving them the training, tools, and knowledge to take care of customers and provide employees with the opportunity to grow to their fullest potential. Together, these four fundamentals contribute to A. O. Smith’s profitable growth. They have served us extremely well for the last 143 years, and I’m certain they will continue to serve us, in 2017 and beyond. Ajita G. Rajendra Chairman and Chief Executive Officer Letter to Shareholders March 2017 A. O. Smith once again enjoyed record-setting results in 2016. Sales increased six percent (eight percent in local currency) to more than $2.69 billion, the seventh consecutive year of record revenue performance. A number of factors contributed to the sales record, most notably impressive 19 percent sales growth (in local currency) for our China operations and continued demand for our commercial water heater and high-efficiency boiler products. Our global water treatment product sales increased to $194 million thanks to growth of 35 percent in China and the addition of Texas-based water treatment company Aquasana, which we acquired in August. Our earnings performance also set a record, increasing 17 percent to $1.85 per share. The higher commercial water heater and boiler volumes and continued double-digit sales growth in China, combined with improved pricing and lower material costs during the first half of the year contributed to the earnings improvement. Earnings were partially offset by lower U.S. residential water heater sales and higher selling costs in China to support expansion into the Tier 2 and Tier 3 cities as well as higher advertising costs to support brand building and the expansion of the air purification product line. Cash flow from operating activities increased an impressive 27 percent to $447 million.

Smith acquired Aquasana, Inc. which designs, assembles and markets premium performance water purification products, including whole-house purification systems which are highlighted above. Water Treatment Business Enters the U.S. and Continues to Expand Globally Water quality needs for U.S. consumers continue to evolve with an aging and deteriorating water infrastructure and an increase in consumer awareness of water quality problems, including unhealthy drinking water throughout the country. Responding to these trends, A. O. Smith entered into the North American market in August 2016 with the acquisition of Texas-based Aquasana, Inc. which designs, assembles and markets premium performance water treatment products. Aquasana sells its whole-house treatment systems, drinking water solutions for at home and on-the-go and shower filters directly to U.S. consumers via www.aquasana.com, as well as its Texas-based call center and direct to the consumer, and through retail outlets and distributers. Aquasana’s drinking water filters remove over 66 harmful contaminants from water including chlorine, chloramines, pharmaceuticals, herbicides, pesticides, industrial solvents, lead, asbestos, and mercury and are engineered to preserve the healthy minerals in water, including calcium, magnesium and potassium. In 2016, the company continued to expand its water treatment line-up around the world, with major advancements in China, India and Turkey and the expansion into Vietnam as well. • China: Nanjing Water Treatment (NWT) started construction on a new 700,000 square foot plant, which is scheduled to begin production in 2018. The new plant will manufacture residential and commercial water treatment products, air purifiers and water softeners. The company also launched a new line of Wifi intelligent reverse osmosis (RO) water treatment products, which can be paired through an APP on a smart-device to alert consumers to any issues. The NWT team recently entered the commercial water treatment market in 15 major markets in China. • India: A. O. Smith entered four additional markets including: Hyderabad, Pune, Kolkata, and Chennai. The company introduced five new water treatment products in 2016 and expanded beyond the RO category with the launch of a unique UV water treatment that offers both ambient and hot water. The two new under-the-counter products, provide a digital display and alarm systems, unique in the industry for under the counter products, and the two new RO models allow for dispensing water at a touch of a button (i.e. electronic faucets). • Turkey: A. O. Smith expanded its presence in the residential and light commercial channels in Istanbul and Ishmair through an exclusive dealer network in those cities. Two new RO units, the Lotus and the Daisy, were also introduced in 2016. • Vietnam: Sales reached $3.5 million in 2016, as the Vietnam team continues to focus its efforts on selling premium RO water treatment products using the patented side-stream membrane technology and continues to develop their sales channels in that country. The Flint, Michigan, water crisis and the continued lead contamination issues throughout the U.S. have created greater consumer awareness of water quality issues; however, more education is needed to inform consumers about Chromium 6, Teflon, and other drinking water contaminants. In addition to marketing innovative, effective water treatment products, A. O. Smith will continue to be a thought leader in this important global industry. In 2016 the company began construction on a new 700,000 square foot plant, which will manufacture residential and commercial treatment products, air purifiers and water softeners in Nanjing, China. shareholders.

We believe this new business presents us with numerous opportunities, as consumers are becoming more aware of water quality issues throughout the U.S. and are seeking healthier alternatives for their families.

Sales of gas tankless water heaters increased more than 20 percent, while heat pump and other renewable water heater technologies also grew at double-digit rates (all measured in local currency). A sizable percentage of our sales are coming from the e-commerce channel, with revenues of nearly $200 at a fast pace, as sales increased nearly 40 percent in the local currency over the prior year. In addition, sales of our air purification line of products nearly tripled over the prior year as Chinese consumers became aware of the air pollution problems in large parts of the country.

Smith has developed a number of tools and services to support its valued partners in the wholesale distribution channel, and that effort will continue in 2017. One of the most visible services is the contractor locator, a lead-generation tool provided on our wholesale websites. The locator uses proprietary geo-locating algorithms to help consumers find a qualified plumber near their home who can install or service their water heater. As products become more diverse and more complex, consumers are asking for assistance in selecting the right water heater for their homes. To meet this need, A. O. Smith has developed an exclusive product sizing tool, available online or as an APP for plumbers to download. The new tool allows plumbers to take a consulting approach in helping guide customers through the water heater sizing and selection process. To further assist with the selection process, A. O. Smith includes rating and reviews for residential water heaters on its web properties. Another important new tool is the Green Sky® consumer financing program that plumbing contractors can offer to their customer. The financing covers not just the water heater, but also installation, and other plumbing services. Overcoming the up- front cost of a water heater purchase has been a barrier to more adoption of energy efficient technologies, and this financing tool has enabled contractors to effectively offer these solutions to their customers. All of these programs are designed to drive business to the company’s channel partners, particularly plumbing contractors. This, combined with the constant introduction of new residential and commercial products, will help the wholesale distribution channel continue to enjoy success for years to come. 11270 West Park Place P.O.

Growth Strategy: Organic Growth China: Lochinvar brands: NA water heaters & other: 32% of sales growing 15% 4.8% 11% of sales growing 8% .9% 57% of sales growing 4% 2.3% Total annual sales growth 8.0% The North American segment unit reported sales increased to $1.74 billion, a 14 percent increase in operating profits to $385.9 million and an impressive 200 basis point increase in operating margin. Higher volumes of boilers and commercial water heaters contributed to the sales increase, and the team in Canada did an excellent job of growing the business in spite of the challenges coming from the strong U.S. dollar. Although sales of Lochinvar-branded products did not increase at the pace we expected, we did add share in the important high-efficiency condensing boiler market. With a large installed base of older, inefficient cast iron boilers in North America, we believe there is room for further growth in this market segment. After a number of years focused on meeting new government efficiency standards, we are now turning our sights to new product development, and 2017 promises to be a busy year in both the commercial and residential segments. Chief among these new products are: • The Cyclone® series 300 with an integrated touchscreen and remote monitoring capability; • The Lochinvar Noble combi boiler that allows us to enter a portion of the residential boiler market in which we were not participating; • The ProLine® series of commercial-grade residential water heaters. These units feature a number of commercial quality components developed by APCOM and, in some cases, come with an eight-year warranty; and • A full suite of electric tankless water heaters, a line of products we have not offered in the past. The Rest of World segment experienced a sales increase of 11 percent to $965.6 million, operating earnings of $129.1 million, a 14 percent increase, and operating margins of 13.4 percent. Our operations in China continue to outperform the Chinese economy, as we take advantage of the well-known A. O. Smith brand in that market. Sales of gas tankless water heaters increased more than 20 percent, while heat pump and other renewable water heater technologies also grew at double-digit rates (all measured in local currency). A sizable percentage of our sales are coming from the e-commerce channel, with revenues of nearly $200 million last year. Water treatment products continue to grow at a fast pace, as sales increased nearly 40 percent in the local currency over the prior year. In addition, sales of our air purification line of products nearly tripled over the prior year as Chinese consumers became aware of the air pollution problems in large parts of the country. To meet the demand for water treatment and air purification products, we began construction of a new 700,000 square foot plant in Nanjing during the fourth quarter of 2016. The new plant, which also will include new product engineering and quality labs, will begin production early next year. Looking ahead, we expect to achieve our eight percent revenue growth model in 2017 as we benefit from an incremental $40 million in Aquasana sales, improved residential water heater sales in the U.S. and continued commercial water heater and boiler sales increases. China’s growth will continue to outpace that country’s economy as we will benefit from household formation, market share gains and higher average selling prices in the water heater market, and the water treatment and air purification product lines once again experience double-digit growth. This outlook is tempered by the likelihood of higher material costs—most notably steel—and the U.S. dollar’s impact on Chinese, Canadian, and other foreign currencies. Nonetheless, I have confidence in the A. O. Smith team and its ability to meet these challenges—as they have in the past—and succeed. Everyone throughout our organization is focused on the Fundamentals for Success, the foundation for everything we do as a company: • Live our values which define who we are, how we do business, and the relationship we have with our customers, suppliers, and the communities in which we do business; • Relentlessly take care of the customer, obsessively understand what our customers want and need in order for them to succeed—and then deliver on those needs; • Invest in innovation in order to provide our customers with market-leading products and solutions; and • Invest in our people by giving them the training, tools, and knowledge to take care of customers and provide employees with the opportunity to grow to their fullest potential. Together, these four fundamentals contribute to A. O. Smith’s profitable growth. They have served us extremely well for the last 143 years, and I’m certain they will continue to serve us, in 2017 and beyond. Ajita G. Rajendra Chairman and Chief Executive Officer Letter to Shareholders March 2017 A. O. Smith once again enjoyed record-setting results in 2016. Sales increased six percent (eight percent in local currency) to more than $2.69 billion, the seventh consecutive year of record revenue performance. A number of factors contributed to the sales record, most notably impressive 19 percent sales growth (in local currency) for our China operations and continued demand for our commercial water heater and high-efficiency boiler products. Our global water treatment product sales increased to $194 million thanks to growth of 35 percent in China and the addition of Texas-based water treatment company Aquasana, which we acquired in August. Our earnings performance also set a record, increasing 17 percent to $1.85 per share. The higher commercial water heater and boiler volumes and continued double-digit sales growth in China, combined with improved pricing and lower material costs during the first half of the year contributed to the earnings improvement. Earnings were partially offset by lower U.S. residential water heater sales and higher selling costs in China to support expansion into the Tier 2 and Tier 3 cities as well as higher advertising costs to support brand building and the expansion of the air purification product line. Cash flow from operating activities increased an impressive 27 percent to $447 million.

Kempken Vice President & Controller John J. Kita Executive Vice President & Chief Financial Officer In August 2016 A. O. Smith acquired Aquasana, Inc. which designs, assembles and markets premium performance water purification products, including whole-house purification systems which are highlighted above. Water Treatment Business Enters the U.S. and Continues to Expand Globally Water quality needs for U.S. consumers continue to evolve with an aging and deteriorating water infrastructure and an increase in consumer awareness of water quality problems, including unhealthy drinking water throughout the country. Responding to these trends, A. O. Smith entered into the North American market in August 2016 with the acquisition of Texas-based Aquasana, Inc. which designs, assembles and markets premium performance water treatment products. Aquasana sells its whole-house treatment systems, drinking water solutions for at home and on-the-go and shower filters directly to U.S. consumers via www.aquasana.com, as well as its Texas-based call center and direct to the consumer, and through retail outlets and distributers. Aquasana’s drinking water filters remove over 66 harmful contaminants from water including chlorine, chloramines, pharmaceuticals, herbicides, pesticides, industrial solvents, lead, asbestos, and mercury and are engineered to preserve the healthy minerals in water, including calcium, magnesium and potassium. In 2016, the company continued to expand its water treatment line-up around the world, with major advancements in China, India and Turkey and the expansion into Vietnam as well. • China: Nanjing Water Treatment (NWT) started construction on a new 700,000 square foot plant, which is scheduled to begin production in 2018. The new plant will manufacture residential and commercial water treatment products, air purifiers and water softeners. The company also launched a new line of Wifi intelligent reverse osmosis (RO) water treatment products, which can be paired through an APP on a smart-device to alert consumers to any issues. The NWT team recently entered the commercial water treatment market in 15 major markets in China. • India: A. O. Smith entered four additional markets including: Hyderabad, Pune, Kolkata, and Chennai. The company introduced five new water treatment products in 2016 and expanded beyond the RO category with the launch of a unique UV water treatment that offers both ambient and hot water. The two new under-the-counter products, provide a digital display and alarm systems, unique in the industry for under the counter products, and the two new RO models allow for dispensing water at a touch of a button (i.e. electronic faucets). • Turkey: A. O. Smith expanded its presence in the residential and light commercial channels in Istanbul and Ishmair through an exclusive dealer network in those cities. Two new RO units, the Lotus and the Daisy, were also introduced in 2016. • Vietnam: Sales reached $3.5 million in 2016, as the Vietnam team continues to focus its efforts on selling premium RO water treatment products using the patented side-stream membrane technology and continues to develop their sales channels in that country. The Flint, Michigan, water crisis and the continued lead contamination issues throughout the U.S. have created greater consumer awareness of water quality issues; however, more education is needed to inform consumers about Chromium 6, Teflon, and other drinking water contaminants. In addition to marketing innovative, effective water treatment products, A. O. Smith will continue to be a thought leader in this important global industry. In 2016 the company began construction on a new 700,000 square foot plant, which will manufacture residential and commercial treatment products, air purifiers and water softeners in Nanjing, China. Wholesale Channel Adapting to Changing Markets, Customers Wholesale distribution is A. O. Smith’s largest water heater market channel and has been since the company began selling residential water heaters more than 70 years ago. Today, as market channels blur due to online technologies and changing consumer preferences, the wholesale channel continues to adapt its business model to the changing competitive environment. Despite the changes, wholesale distribution remains positioned to thrive in the long term, due to a number of factors: • As water heaters become more complex, they require professional installation. Wholesale distribution is closely aligned with plumbing contractors; • Distributors remain the major driver in commercial water heating due to innovative programs that make products and support available 24/7; • Wholesale distribution, with its extensive logistics capabilities, is well-adapted to serve the new construction market. Wholesale distributors are responding to a new generation of consumers who are more engaged in any purchase that affects their homes. Whereas, in the past, many wholesalers discouraged direct consumer contact, today they are opening large, well-appointed showrooms and utilizing digital marketing tools to attract customers, particularly millennials. The term for this approach is “omni-channel,” which means creating the same environment for a customer no matter how he or she wants to shop. Senior Leadership Charles T.

Vallett, Jr. Senior Vice President, Chief Executive Officer- Lochinvar, LLC Kevin J. Wheeler Senior Vice President and General Manager- North America, India, Europe & Export The upgraded product sizing APP is designed to help plumbing contractors guide consumers through the water heater selection process. The new APP is the latest in a series of online tools designed to help plumbing contractors offer more value to their customers. Engineering Technician Jamie Wilks checks the remote monitoring capability of a Cyclone® series 300 high efficiency water heater under test in the commercial product engineering center. The Cyclone 300, which was introduced in January, offers remote monitoring through a smart phone APP to help customers keep tabs on water heater performance. Over the last several years, A. O. Smith has developed a number of tools and services to support its valued partners in the wholesale distribution channel, and that effort will continue in 2017. One of the most visible services is the contractor locator, a lead-generation tool provided on our wholesale websites. The locator uses proprietary geo-locating algorithms to help consumers find a qualified plumber near their home who can install or service their water heater. As products become more diverse and more complex, consumers are asking for assistance in selecting the right water heater for their homes. To meet this need, A. O. Smith has developed an exclusive product sizing tool, available online or as an APP for plumbers to download. The new tool allows plumbers to take a consulting approach in helping guide customers through the water heater sizing and selection process. To further assist with the selection process, A. O. Smith includes rating and reviews for residential water heaters on its web properties. Another important new tool is the Green Sky® consumer financing program that plumbing contractors can offer to their customer. The financing covers not just the water heater, but also installation, and other plumbing services. Overcoming the up- front cost of a water heater purchase has been a barrier to more adoption of energy efficient technologies, and this financing tool has enabled contractors to effectively offer these solutions to their customers. All of these programs are designed to drive business to the company’s channel partners, particularly plumbing contractors. This, combined with the constant introduction of new residential and commercial products, will help the wholesale distribution channel continue to enjoy success for years to come. 11270 West Park Place P.O.
