PART 1 ITEM 1 - BUSINESS - ----------------- We are a leading manufacturer of electric motors and water heating equipment, serving a diverse mix of residential, commercial, and industrial end markets principally in the United States with a growing international presence. Our company is organized in two segments: Electrical Products and Water Systems. Our Electrical Products business manufactures and markets a comprehensive line of hermetic motors, fractional horsepower alternating current (AC) and direct current (DC) motors, and integral horsepower motors. Our Water Systems business manufactures and markets a comprehensive line of residential gas and electric water heaters, standard and specialty commercial water heating equipment, high-efficiency copper-tube boilers, and water systems tanks. In 2002, we had net sales of approximately $1.5 billion, with 54 percent attributable to our Electrical Products business and 46 percent attributable to our Water Systems business. During the past six years, we have significantly repositioned our company. We have changed from a diversified manufacturer with five businesses, the largest of which was our legacy automotive structural components business that represented more than 50 percent of our total sales, to a company focused on our Electrical Products and Water Systems businesses, which we believe offer the opportunity for higher growth and more profitability. The following table summarizes our net sales by operating segment. This segment 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 elsewhere in this document. Years Ended December 31 (dollars in millions) --------------------------------------------- 2002 2001 2000 1999 1998 ---- ---- ---- ---- ---- Electrical Products $ 790.4 $ 802.7 $ 902.4 $ 735.0 $487.4 Water Systems 678.7 348.5 345.5 335.3 313.4 -------- -------- -------- -------- ------- Total Operations $1,469.1 $1,151.2 $1,247.9 $1,070.3 $800.8 ======== ======== ======== ======== ======= ElectricAL PRODUCTS Our Electrical Products segment sales decreased $12 million or two percent in 2002 to $790 million. Excluding the third quarter 2002 acquisition of the hermetic motor assets of the Athens Products (Athens) division of the Electrolux Group, segment sales declined approximately $32 million or four percent. The decrease in sales in 2002 was primarily due to lower sales of motors to the heating, ventilating, and air-conditioning (HVAC) market. We are one of the three largest manufacturers of electric motors in North America, having manufactured approximately 36 million electric motors in 2002. We offer a comprehensive line of hermetic motors, fractional horsepower AC and DC motors, and integral horsepower motors, ranging in size from sub-fractional C-frame ventilation motors up to 500 horsepower hermetic and 800 horsepower specialty integral motors. We believe our extensive product offering gives us an advantage in our targeted markets, often allowing us to serve all of our customers electric motor needs. We have significantly broadened our electric motor product line and customer base through a series of acquisitions over the last six years, including 2

UPPCO, General Electric Company's domestic hermetic motor business, MagneTek's electric motor business, and the hermetic motor assets of Athens. Our motors are used in a wide range of targeted residential, commercial, and industrial applications, including: hermetic motors that are sold worldwide to manufacturers of air conditioning and commercial refrigeration compressors; fractional horsepower fan motors used in furnaces, air conditioners, and blowers; fractional horsepower motors for pumps for home water systems, swimming pools, hot tubs, and spas; fractional horsepower motors used in other consumer products (such as garage door openers); and integral horsepower AC and DC motors for industrial and commercial applications. Sales to the heating, ventilating, air conditioning and refrigeration market account for more than 60 percent of segment sales. In July 2002, we expanded our presence in the hermetic motor market by acquiring Athens. Approximately 85 percent of our 2002 segment sales were to original equipment manufacturers (OEM) in a diverse mix of industries, with the remainder of sales directed to the aftermarket or distribution channels. Sales to our largest customer, York International and its wholly owned Bristol Compressors subsidiary, were $173 million in 2002 and represented approximately 22 percent of segment sales. We believe that more than 25 percent of our total segment sales were attributable to products used outside of the United States. We estimate that approximately 60 percent of the market is derived from the less cyclical replacement business with the remainder being impacted by general business conditions in the new construction market. To remain a leader in this highly competitive industry, we are committed to being a low-cost supplier of electrical products. We were one of the first motor manufacturers to identify the cost-reduction potential of Mexican operations, and today we manufacture a majority of our electric motors in our 16 Mexican motor facilities. In late 2001, we undertook an initiative to accelerate the cost-reduction programs that were already underway in our motor operations to enhance our competitive position. These initiatives included transferring six additional product manufacturing lines to our lower-cost Mexican operations; reducing salaried workforce by 10 percent; and realigning our warehouse facilities into three hub operations to improve customer service while reducing cost. In December 2001, we acquired Shenzhen Speeda, a manufacturer of sub-fractional horsepower electric motors in China. In December 2002, we acquired the motor manufacturing assets of Jiangsu Changheng Group Co. Ltd. (Changheng), of Changzhou, China. While Changheng has an existing customer base in China, the primary purpose of the Chinese acquisitions is to further expand our ability to manufacture products for the U.S. market. Our principal competitors in the electric motor industry are Emerson Electric Co. and General Electric Company. A number of other companies, such as Fasco Motors, Baldor Electric, Regal-Beloit Corporation, and Jakel Incorporated, compete with us in specific segments of the electric motor market. WATER SYSTEMS Our Water Systems business had sales in 2002 of $679 million, $330 million higher than 2001 sales of $349 million. The higher sales were the result of $313 million in sales from the acquisition of State Industries Inc. (State). Excluding State, sales increased approximately 5 percent. The majority of the company's sales are in the less cyclical replacement market, although the new housing market is also an important market for the business. We serve residential, commercial, and industrial end markets with a broad range of products, including: Residential gas and electric water heaters. Our residential water heaters come in sizes ranging from two-gallon (point-of-use) models to 120-gallon appliances with varying efficiency ranges. We offer traditional atmospheric water heaters as well as direct-vented and power-vented models for today's energy efficient homes. Domestic residential water heater sales in 2002 were $430 million or approximately 63 percent of segment revenues. 3

Standard commercial water heaters. Our gas, oil, and electric water heaters come in capacities ranging from 50 to 100 gallons and are used by customers who require a consistent, economical source of hot water. Typical applications include restaurants, hotels and motels, laundries, car washes, and small businesses. Our Water Systems business also manufactures and markets specialty commercial water heaters, copper-tube boilers, expansion tanks, and related products and parts. We are one of the two largest manufacturers and marketers of water heaters in North America, manufacturing more than three million units in 2002. We have a leading share in the commercial water heating segment, and we believe we are the only domestic manufacturer that offers standard and specialty commercial water heater products. We believe that our comprehensive commercial product line gives us a competitive advantage in this higher-margin segment of the water heating industry. We also are one of the leaders in the residential water heating segment with an extensive line of high-efficiency gas and electric models. We significantly broadened our market scope and product offering with the acquisition of State. This acquisition allowed us to enter the retail segment of the residential market, a channel that represents approximately one-half of the total United States residential market. The acquisition of State also enhanced our position in the wholesale distribution channel and gave us a position in several new distribution channels, such as direct sales to large homebuilders and the manufactured housing market. An increasing number of government regulations will have a significant impact on the United States water heating industry in the coming years, and we believe we will benefit from our engineering expertise in this challenging environment. Beginning in July of this year, United States water heater manufacturers will be required to comply with new flammable vapor ignition resistance standards for virtually all residential gas water heaters. These new standards and testing protocols established by the American National Standards Institute (ANSI) require that gas water heaters deal with the accidental ignition of flammable vapors, such as emitted by spilled gasoline or other liquids. Other regulations impacting our markets include restrictions on water heater emissions of nitrogen oxides (to date mandated only in California and Texas) and a United States government requirement to increase the efficiency of residential gas and electric water heaters by January 2004. We believe we will successfully comply with these new regulations on a timely basis. Our water systems wholesale distribution channel includes more than 2,600 wholesale plumbing distributors that serve residential, commercial, and industrial markets. We also sell our residential water heaters through the retail channel. In this channel, our customers include four of the six largest national hardware and home center chains, including a long-standing private label relationship with Sears, Roebuck and Co. Our principal domestic water heating competitors include Rheem Manufacturing Company, Inc. and, to a lesser extent, American Water Heater Company and Bradford-White Corporation. 4

RAW MATERIAL Raw materials for our manufacturing operations, which consist primarily of steel, copper, and aluminum, are generally available from several sources in adequate quantities. We hedge the majority of our annual copper purchases to protect against price volatility. SEASONALITY There is no significant seasonal pattern to our consolidated quarterly sales and earnings. RESEARCH AND DEVELOPMENT, PATENTS, AND TRADEMARKS In order to improve competitiveness by generating new products and processes, we conduct research and development at our Corporate Technology Center in Milwaukee, Wisconsin as well as at our operating units. Total expenditures for research and development in 2002, 2001, and 2000, were approximately $30.4, $27.6, and $24.5 million, respectively. We own and use in our businesses various trademarks, trade names, patents, trade secrets, and licenses. While a number of these are important to us, we do not consider a material part of our business to be dependent on any one of them. EMPLOYEES Our company and its subsidiaries employed approximately 16,200 employees as of December 31, 2002. BACKLOG Normally, none of our operations sustain significant backlogs. ENVIRONMENTAL LAWS Our operations are governed by a variety of federal, state, and local laws intended to protect the environment. While environmental considerations are a part of all significant capital expenditures, compliance with the environmental laws has not had a material effect and is not expected to have a material effect upon the capital expenditures, earnings, or competitive position of our company. See Item 3. FOREIGN SALES Total U.S. export sales from our operations were $90, $91, and $62 million in 2002, 2001, and 2000, respectively.

ITEM 7 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS - -------------------------------------------------------------------------------- OF OPERATIONS - ------------- LIQUIDITY AND CAPITAL RESOURCES We recorded net earnings of $51.3 million or $1.86 per share in 2002, significantly higher than the $14.5 million or $.61 per share earned in 2001. The significant improvement in earnings was primarily a result of cost reduction actions in our Electrical Products business and integration activities related to the acquisition of State. The Water Systems business established new sales and earnings records in 2002. Individual segment performance will be discussed later in this section. Our working capital for continuing operations at December 31, 2002, was $228.1 million compared with $219.8 million and $204.3 million at December 31, 2001 and 2000, respectively. The increase in our working capital in 2002 was due to higher cash balances and the increase in 2001 was due to the acquisition of State in December 2001. Cash flow from operating activities during 2002 was $112.2 million compared with $49.8 million in 2001. Significantly higher earnings levels and a $12.4 million tax refund received in March 2002 explain the majority of the improvement. Our capital expenditures were $42.5 million in 2002 compared with $35.3 million in 2001 and $40.5 million in 2000. The increase in 2002 was associated with our acquisition of State. The decrease in capital spending in 2001 occurred in our Electrical Products business. We are projecting 2003 capital expenditures to be approximately $45 million and marginally lower than projected 2003 depreciation expense. Our cash flow during 2003 is expected to adequately cover our projected capital expenditures. We believe that our present facilities and planned capital expenditures are sufficient to provide adequate capacity for our operations in 2003. On May 10, 2002, we completed the sale of 4.8 million shares of our common stock through a public offering at a price of $28.25 per share. With the $127.5 million net proceeds from our stock offering and operating cash flow, we reduced our debt by $156.2 million from $406.9 million at December 31, 2001, to $250.7 million at December 31, 2002. Our leverage, as measured by the ratio of total debt to total capitalization, was 33 percent, down significantly from 47 percent at the end of 2001. Excluding potential acquisitions, we expect 2003 cash flow to result in a year-end leverage ratio less than 30 percent. We expect to have adequate liquidity in 2003 as we have a minimal amount of long-term debt maturing. In addition, we have a $250.0 million multi-year revolving credit facility with a group of nine financial institutions that expires on August 2, 2004, and an $82.5 million 364-day credit facility with a group of six banks that expires on July 25, 2003. We expect these credit facilities are adequate to support any short-term borrowing needs. At December 31, 2002, we had available borrowing capacity of $222.1 million under our credit facilities. For information about our contractual obligations for indebtedness, capital leases, operating leases and related obligations as of December 31, 2002, see Note 9 of Notes to Consolidated Financial Statements. We believe that the combination of available borrowing capacity and operating cash flow will provide sufficient funds to finance our existing operations for the foreseeable future. Recent declines in the U.S. equity market have resulted in a reduction in the fair value of the assets of our pension plans. This asset value reduction, coupled with an increase in the present value of the obligations of our pension plans due to declining interest rates, has resulted in accumulated pension benefit obligations exceeding the fair value of the plan assets by $89 million. Accordingly, we took a non-cash charge to equity of $115 million, representing the recording of this liability, the elimination of the prepaid asset, and related deferred tax effects. This charge has no impact on current cash flow or net earnings. Our pension plans continue to meet all funding requirements under ERISA regulations, and under current assumptions, we do not expect any significant minimum funding requirements for several years. See Note 12 of Notes to Consolidated Financial Statements. 11

In connection with our acquisition of Athens in July 2002, we recorded purchase liabilities of $4.2 million primarily for employee severance costs associated with product manufacturing repositioning. As of December 31, 2002, we have charged $1.1 million against this reserve. In connection with the Athens acquisition and certain other acquisitions, we recorded aggregate purchase liabilities of $26.5 million at the respective acquisition dates for employee severance and relocation, as well as certain facility exit costs. As of December 31, 2002, we incurred and charged $17.1 million against these liabilities. We expect the majority of the activities to be completed by December 31, 2003. Included in other assets is a $34.0 million receivable due to the payments of claims associated with the dip tube class action lawsuit. See Note 14 of Notes to Consolidated Financial Statements. We expect a modest increase to the receivable in 2003. The receivable is classified as a long-term asset because court proceedings will not begin until late 2003 and may not be concluded until 2004 or later. We have paid dividends for 63 consecutive years. We paid total dividends of $.54 per share in 2002 compared with $.52 per share in 2001. 12

RESULTS OF OPERATIONS Our sales in 2002 were $1.47 billion, an increase of $317.9 million or 27.6 percent from sales of $1.15 billion in 2001. The sales increase was due to our acquisitions of State in December 2001 and Athens in July 2002 as well as higher sales in our base water heater business partially offset by a modest decline in our electric motor business. Sales in 2001 decreased by $96.8 million or 7.8 percent from sales of $1.25 billion in 2000. The lower sales resulted from an 11.0 percent decline in our Electrical Products segment, which more than offset a slight increase in sales for our Water Systems business. Our gross profit margin for 2002 was 20.4 percent, compared with 17.6 percent and 19.9 percent in 2001 and 2000, respectively. The significant improvement in margin from 2001 to 2002 resulted from lower manufacturing costs associated with the product repositioning program at Electrical Products and the integration of the State acquisition. The decline in gross margin from 2000 to 2001 occurred within our Electrical Products segment and was due primarily to under-absorption of manufacturing costs associated with lower volume, Mexican wage inflation throughout the year, and increased costs for certain raw materials. Selling, general and administrative expense (SG&A) in 2002 was $206.2 million and increased by $60.5 million from the $145.7 million recorded in 2001 primarily as a result of incremental SG&A associated with the State acquisition. SG&A in 2001 was $8.0 million lower than 2000. The decrease resulted from volume-related reductions in selling expense and cost reduction programs. We have significant pension benefit costs and credits that are developed from actuarial valuations. The valuations reflect key assumptions regarding, among other things, discount rates, expected return on plan assets, retirement ages, and years of service. Consideration is given to current market conditions, including changes in interest rates, in making these assumptions. Our assumption for the expected rate of return on pension plan assets was 9.75 percent in 2002 compared with 10.0 percent in 2001. Our 2003 assumption for return on assets reflects a further reduction to 9.0 percent which should result in pension income recognition of approximately $10.0 million in 2003. We recognized pension income of $17.1 million, $20.2 million, and $17.7 million in 2002, 2001, and 2000 respectively, reflected as reductions to cost of products sold and SG&A. See Note 12 of Notes to Consolidated Financial Statements. In developing our expected long-term rate of return assumption, we evaluated our pension plan's target asset allocation, historical long-term rates of return of equity and bond indices, and actual historical returns of our pension plan. Our plan's target allocation to equity managers is 65 percent and the target allocation to bond managers is 35 percent. Due to market fluctuations, our actual asset allocation as of December 31, 2002, was 60 percent to equity managers and 40 percent to bond managers. We regularly review our actual asset allocation and periodically rebalance our investments to our targeted allocation when considered appropriate. We also considered our pension plan's historical 10-year and 25-year compounded annualized returns of 10.8 percent and 12.7 percent, respectively. We believe that with our target allocation and the historical long-term returns of equity and bond indices, as well as our actual historical returns, our 9.0 percent expected return on assets for 2003 is reasonable. The discount rate that we utilize for determining future pension obligations is based on the average yield of Moody's Aa Corporate Bonds. The discount rate determined on this basis has decreased from 7.25 percent at December 31, 2001, to 6.75 percent at December 31, 2002. We will continue to evaluate our actuarial assumptions at least annually, and we will adjust the assumptions as necessary. Interest expense was $13.9 million in 2002, compared with $16.4 million and $22.1 million in 2001 and 2000, respectively. Decreasing interest rates throughout the past three years coupled with a significant reduction in debt resulting from our stock offering in May 2002 were responsible for the downward trend in interest expense. See Note 9 of Notes to Consolidated Financial Statements. Amortization of intangibles decreased to $0.3 million in 2002 from approximately $7.0 million in both 2001 and 2000. We adopted Statement of Financial Accounting Standards (SFAS) No. 142, "Goodwill and Other Intangible 13

Assets" as of January 1, 2002. Under the new standard, goodwill and indefinite-lived intangible assets are no longer amortized but instead are reviewed annually for impairment, and accordingly goodwill amortization of $6.7 million in 2001 and 2000 was not recorded in 2002. See Note 8 of Notes to Consolidated Financial Statements. Other expense decreased slightly to $1.0 million from $1.4 million in 2001. The $1.1 million increase from 2000 to 2001 was due mostly to losses incurred on forward foreign currency contracts. Our effective tax rate was 34.5 percent in 2002, 35.5 percent in 2001, and 36.0 percent in 2000. The effective rate in 2002 benefited from the implementation of a more efficient tax structure for international operations. The decline in the rate from 2000 to 2001 resulted from increased research and state tax credits, partially offset by the negative impact of the losses in low-tax foreign jurisdictions. We recorded net earnings of $51.3 million or $1.86 per share in 2002 compared with $14.5 million or $.61 per share in 2001. Net earnings in 2001 included a $6.0 million after-tax special charge ($.25 on a per share basis) related primarily to the restructuring of our electric motor operation. Electrical Products On July 1, 2002, we purchased the hermetic motor assets of Athens for approximately $9.7 million. Athens, based in Athens, Tennessee, is a manufacturer of hermetic motors for both scroll and reciprocating compressors. This purchase is expected to generate incremental sales in 2003 of approximately $20 million and modest earnings in the second half of the year. In the fourth quarter of 2002, we also acquired the motor manufacturing assets of Jiangsu Changheng Group Co. Ltd. (Changheng) for approximately $15.3 million. Changheng is located in the JiangSu province of China and manufactures air-moving motors for the Chinese air conditioning market. Although Changheng has an existing customer base in China, the primary purpose of the acquisition is to further expand our ability to manufacture products for the U.S. market. See Note 2 of Notes to Consolidated Financial Statements. Sales in our Electrical Products segment in 2002 were $790.4 million, $12.3 million lower than 2001 sales of $802.7 million. Excluding approximately $20 million in sales attributable to the Athens acquisition, sales declined by $32.0 million from 2001 to 2002. Sales to the heating, ventilating, and air conditioning (HVAC) market, excluding Athens, declined by six percent in 2002 and accounted for the majority of the total decrease in sales. Sales in 2000 were $902.4 million. The HVAC market experienced a decline of approximately $60 million or 11 percent from 2000 to 2001. The lower demand in 2001 was due to a number of factors including general economic conditions, reduced discretionary spending on the part of consumers, and inventory adjustments by air conditioning manufacturers and retailers. Operating earnings for our Electrical Products segment in 2002 were $57.6 million or $22.1 million higher than 2001 earnings adjusted to exclude goodwill amortization expense of $6.7 million and special pretax charges of $8.1 million in 2001. The increased earnings were primarily due to the cost reduction program announced in the fourth quarter of 2001. The program consisted of three major elements: consolidation of warehouse facilities; reduction of approximately 150 salaried employees; and relocation of production from six domestic facilities to Mexico and China. The combination of these actions was expected to generate savings of $16 million in 2002 and $20 to $25 million annually thereafter. During 2002, we exceeded our goal and generated $19 million in first-year savings and project 2003 cost savings to exceed $25 million. Operating earnings in 2000 were $75.5 million and compare with earnings of $28.9 million excluding the special pretax charge of $8.1 million in 2001. The significant decline in 2001 earnings was due mostly to lower sales volume, higher costs for raw materials and Mexican labor, and more competitive market conditions. Water Systems Sales for our Water Systems segment were $678.7 million in 2002, or $330.2 million higher than sales of $348.5 million in 2001. The State acquisition contributed $312.6 million of the increase. The remaining increase was attributable to higher volume for the base residential and commercial business and the China operation. The slight 14

increase in 2001 sales from $345.5 million in 2000 was due to higher sales of residential products and growth in the China operation, partially offset by lower sales in other international markets. Operating earnings for our Water Systems segment were $58.4 million or $17.9 million higher than 2001 earnings of $40.5 million before special charges. The higher earnings in 2002 were the result of the State acquisition and its related synergies, and increased sales volume in the base business. The earnings improvement from $34.9 million in 2000 to $40.5 million before special charges in 2001 was the result of higher volume, better performance in China, and improved plant efficiencies throughout the organization. During 2002, we moved the Water Systems segment headquarters from Irving, Texas to Ashland City, Tennessee, State's headquarters, to facilitate the integration of the two businesses. A special pretax charge of $1.3 million was recognized in the fourth quarter of 2001 for lease and certain other costs associated with this move. 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 United States 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 recoverability of certain assets including goodwill and receivables resulting from the payment of claims associated with the dip tube class action lawsuit (see Note 14 of Notes to Consolidated Financial Statements) as well as those estimates used in the determination of liabilities related to warranty activity, litigation, product liability, environmental matters, and pensions and other post-retirement benefits. 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 constantly reevaluate these significant factors and adjustments are made when facts and circumstances dictate. Historically, actual results have not significantly deviated from those determined using the estimates described above. Recent Accounting Pronouncements The Financial Accounting Standards Board has issued SFAS No. 143, "Accounting for Asset Retirement Obligations," SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities," and SFAS No. 148, "Accounting for Stock-Based Compensation - Transition Disclosures." SFAS No. 143 will become effective for us on January 1, 2003. Adoption of this statement is not expected to have a material impact on our consolidated financial statements. SFAS No. 144, which was adopted on January 1, 2002, has not had a material impact on our consolidated financial statements since its adoption. SFAS No. 146 will be effective for exit or disposal activities initiated after December 31, 2002. Adoption of this statement is not expected to have a material impact on our consolidated financial statements. Effective December 31, 2002, we began making the disclosures required under SFAS No. 148. Outlook Our overall cost structure improved significantly during 2002. Our operating units will continue to aggressively manage cost in the new year, and we remain confident in our full-year 2003 earnings estimate of between $2.05 and $2.25 per share. While we are confident in the full-year estimate, earnings improvement will occur primarily in the last half of the year. Cost increases, including pension, employee medical costs, and liability insurance will impact us throughout the year. Operating improvements, however, will build up incrementally during the year and are weighted to the last half of the year. These improvements include the continued success of the motor repositioning programs, the ongoing impact of the State integration activities, and the introduction of new water heater products. For the first 15

quarter of 2003, net earnings are projected to modestly surpass last year's $12.1 million result. However, given the impact from our second quarter 2002 stock offering, our first quarter earnings forecast of $.41 to $.45 per share will fall short of last year's figure of $.50 per share. OTHER MATTERS Environmental Our operations are governed by a number of federal, state, and local 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 2002 and are not expected to be material in any single year. Although we believe that our operations are substantially in compliance with such laws and maintain procedures designed to maintain compliance, there are no assurances that substantial additional costs for compliance will not be incurred in the future. However, since the same laws govern our competitors, we should not be placed at a competitive disadvantage. Market Risk We are exposed to various types of market risks, primarily currency and certain commodities. We monitor our risks in such areas on a continuous basis and generally enter into forward and futures 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. Commodity risks include raw material price fluctuations. We use futures contracts to fix the cost of our expected needs with the objective of reducing price risk. Futures contracts are purchased over time periods and at volume levels which approximate expected usage. At December 31, 2002, we had commodity futures contracts amounting to $56 million of commodity purchases. A hypothetical 10 percent change in the underlying commodity price of such contracts would have a potential impact of $5.6 million. It is important to note that gains and losses from the company's futures contract activities will be offset by gains and losses in the underlying commodity purchase transactions being hedged. In addition, we enter into foreign currency forward contracts to minimize the effect of fluctuating foreign currencies. At December 31, 2002, we had net foreign currency contracts outstanding of $94.0 million. Assuming a hypothetical 10 percent movement in the respective currencies, the potential foreign exchange gain or loss associated with the change in rates would amount to $9.4 million. It is important to note that gains and losses from our forward contract activities 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, 2002, we had $116.9 million in outstanding floating-rate debt with a weighted-average interest rate of 2.0 percent at year end. A hypothetical 10 percent annual increase or decrease in the year-end average cost of our outstanding floating-rate debt would result in a change in annual pretax interest expense of $0.2 million. Forward-Looking Statements This report contains statements that we believe are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally can be identified by the use of words such as "may," "will," "expect," "intend," "estimate," "anticipate," "believe," "continue," "expectation," or words of similar meaning. These forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those anticipated as of the date of this filing. Factors that could cause such a variance include the following: instability in our electric motor and water heater markets; inability to generate the synergistic cost savings from the acquisition of State; the inability to implement cost-reduction programs; adverse changes in general economic conditions; significant increases in raw material prices; a regulatory delay or a failure to comply with new flammable vapor ignition resistant standards in the residential gas water heater industry; 16

competitive pressures on our businesses; and the potential that assumptions on which we have based our expectations are inaccurate or will prove to be incorrect. Forward-looking statements included in this report are made only as of the date of the filing, and we are under no obligation to update these statements to reflect subsequent events or circumstances. All subsequent written and oral forward-looking statements attributable to us, or persons acting on our behalf, are qualified in their entirety by these cautionary statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. Organization and Significant Accounting Policies Organization. A. O. Smith Corporation (the company) is a manufacturer serving customers worldwide. The company's major product lines include fractional and integral horsepower alternating current (A/C), direct current (D/C), and hermetic electric motors, as well as residential and commercial water heaters. The company's products are manufactured and marketed primarily in North America. Electric motors are sold principally to original equipment manufacturers and industrial distributors. Water heaters are sold principally to plumbing wholesalers and retail outlets. Consolidation. The consolidated financial statements include the accounts of the company and its wholly owned subsidiaries after elimination of intercompany transactions. Use of estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 and cash equivalents, receivables, and trade payables approximated fair value as of December 31, 2002 and 2001, due to the short maturities of these instruments. The carrying amount of long-term debt approximated fair value as of December 31, 2002 and 2001, based on current rates offered to the company for debt with the same or similar maturities. Foreign currency translation. For all subsidiaries outside the United States, with the exception of Mexico and the China operations of the company's Electrical Products segment, 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 Mexico and China operations of the company's Electrical Products segment use the U.S. dollar as the functional currency as such operations are a direct and integral component of the company's U.S. operations. Gains and losses from foreign currency transactions are included in net earnings. Cash and cash equivalents. The company considers all highly liquid investments, generally with a maturity of three months or less when purchased, to be cash equivalents. Inventory valuation. Inventories are carried at lower of cost or market. Cost is determined on the last-in, first-out (LIFO) method for substantially all domestic inventories which comprise 92 percent and 93 percent of the company's total inventory at December 31, 2002 and 2001, respectively. Inventories of foreign subsidiaries 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 and 5 to 20 years for equipment. Maintenance and repair costs are expensed as incurred. Goodwill and other intangibles. The company adopted Statement of Financial Accounting Standards (SFAS) No. 142 "Goodwill and Other Intangible Assets" effective January 1, 2002. Under SFAS No. 142, goodwill and indefinite-lived intangible assets (totaling $3.0 million at December 31, 2002) are no longer amortized but are reviewed for impairment on an annual basis. Separable intangible assets that are not deemed to have an indefinite life are amortized on a straight-line basis over their estimated useful lives which range from 5 to 30 years. 24

1. Organization and Significant Accounting Policies (continued) Impairment of long-lived and amortizable intangible assets. Property, plant, and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset or group of assets, a loss is recognized for the difference between the fair value and carrying value of the asset or group of assets. Such analyses necessarily involve significant judgment. Derivative instruments. Effective January 1, 2001, the company adopted SFAS No. 133, as amended, which 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. Any fair value changes are recorded in net earnings or other comprehensive earnings (loss). The cumulative effect of adopting SFAS No. 133 was not material to the company's consolidated financial statements as of January 1, 2001. The company utilizes certain derivative instruments to enhance its ability to manage currency exposures and raw materials price risks. 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. Commodity Future Contracts In addition to entering into supply arrangements in the normal course of business, the company also enters into futures contracts to fix the cost of certain raw material purchases, principally copper, with the objective of minimizing changes in cost due to market price fluctuations. The commodity futures contracts are designated and accounted for as cash flow hedges of a forecasted transaction. Derivative commodity liabilities of $1.8 and $6.9 million are recorded in accrued liabilities as of December 31, 2002 and 2001, respectively, with the value of the effective portion of the contracts of $1.7 and $6.9 million recorded in accumulated other comprehensive earnings (loss), net of tax, and reclassified into cost of products sold in the period in which the underlying transaction is recorded in earnings. Ineffective portions of the commodity hedges are recorded in earnings in the period in which the ineffectiveness occurs. The impact of hedge ineffectiveness on earnings was not material for the years ended December 31, 2002 and 2001, respectively. 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. Contracts typically have maturities of one year or less. Principal currencies include the Mexican peso, Hungarian forint, British pound, Euro, and U.S. dollar. Forward contracts are designated and accounted for as cash flow hedges of a forecasted transaction. Derivative currency liabilities of $3.9 million as of December 31, 2002, are recorded in other current liabilities, and derivative currency assets of $6.6 million as of December 31, 2001, are recorded in other current assets. Gains and losses on these instruments are recorded in accumulated other comprehensive earnings (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 earnings (loss) to the 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 perfectly effective. 25

1. Organization and Significant Accounting Policies (continued) The majority of the amounts in accumulated other comprehensive earnings (loss) for cash flow hedges is expected to be reclassified into earnings within one year. The following table summarizes, by currency, the contractual amounts of the company's foreign currency forward contracts. December 31 (dollars in thousands) 2002 2001 - -------------------------------------------------------------------------------- Buy Sell Buy Sell --- ---- --- ---- Euro $ 2,980 $1,960 $ 3,900 $1,560 British pound - - 2,824 1,525 Hungarian forint 3,179 - 3,394 - Mexican peso 89,831 - 74,279 - ------- ------ ------- ------ Total $95,990 $1,960 $84,397 $3,085 ======= ====== ======= ====== The forward contracts in place at December 31, 2002 and 2001, amounted to approximately 95 percent and 85 percent, respectively, of the company's anticipated subsequent year exposure for those currencies hedged. Revenue recognition. The company recognizes revenue upon transfer of title, which generally occurs upon shipment of the product to the customer. Compensated absences. In the fourth quarter of 2001 and the second quarter of 2000, the company changed its vacation policy for certain employees so that vacation pay is earned ratably throughout the year and must be used by year-end. The accrual for compensated absences was reduced by $1.6 and $2.3 million in 2001 and 2000, respectively, to eliminate vacation pay no longer required to be accrued under the current policy. Research and development. Research and development costs are charged to operations as incurred and amounted to $30.4, $27.6, and $24.5 million during 2002, 2001, and 2000, respectively. Product warranty. The company offers warranties on the sales of certain of its products and records an accrual for estimated future claims. Such accruals are based upon historical experience and management's estimate of the level of future claims. The following table presents the company's product warranty liability activity in 2002 and 2001: 2002 2001 ---- ---- Balance at beginning of year $ 69,632 $ 29,205 Expense 32,738 19,068 Acquired obligations 73 40,028 Claims settled (31,928) (18,669) -------- -------- Balance at end of year $ 70,515 $ 69,632 ======== ======== Environmental costs. The company accrues for losses associated with environmental obligations when such losses 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. 26

1. Organization and Significant Accounting Policies (continued) Stock based compensation. The company has one stock-based employee compensation plan (see Note 11). SFAS No. 123, "Accounting for Stock-Based Compensation," encourages, but does not require companies to record compensation cost for stock-based employee compensation plans at fair value. The company has chosen to continue applying Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," and related interpretations, in accounting for its stock option plans. Accordingly, because the number of shares is fixed and the exercise price of the stock options equals the market price of the underlying stock on the date of grant, no compensation expense has been recognized. Had compensation cost been determined based upon the fair value at the grant date for awards under the plans based on the provisions of SFAS No. 123, the company's pro forma earnings and earnings per share would have been as follows: Years ended December 31 (dollars in thousands, except per share amounts) 2002 2001 2000 - -------------------------------------------------------------------------------------------------------------------------- Earnings: As reported $51,345 $14,502 $41,656 Deduct: Total stock based employee compensation expense determined under fair value based method, net of tax (1,669) (1,775) (1,326) ------- ------- ------- Pro forma $49,676 $12,727 $40,330 ======= ======= ======= Earnings per share: As reported: Basic $1.90 $0.61 $1.78 Diluted 1.86 0.61 1.76 Pro forma: Basic $1.84 $0.54 $1.72 Diluted 1.80 0.53 1.70 Earnings per share of common stock. 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: 2002 2001 2000 - -------------------------------------------------------------------------------------------------------------------------- Denominator for basic earnings per share--weighted- average shares outstanding 27,002,102 23,648,136 23,396,210 Effect of dilutive stock options 646,964 266,646 294,932 ---------- ---------- ---------- Denominator for diluted earnings per share 27,649,066 23,914,782 23,691,142 ========== ========== ========== Reclassifications. Certain prior year amounts have been reclassified to conform to the 2002 presentation. New accounting standards. During 2002, the Financial Accounting Standards Board issued SFAS No. 143, "Accounting for Asset Retirement Obligations," SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities," and SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure." SFAS No. 143 will become effective for the company on January 1, 2003. Adoption of this statement is not expected to have a material impact on the company's consolidated financial statements. SFAS No. 144, which was adopted on January 1, 2002, did not have a material impact on the company's consolidated financial statements since its adoption. SFAS No. 146 will be effective for exit or disposal activities initiated after December 31, 2002. Adoption of this statement is not expected to have a material impact on the company's consolidated financial statements. Effective December 31, 2002, the company made the disclosures required under SFAS No. 148. 27

2. Acquisitions In 2002, the company acquired certain net assets of the Athens Products (Athens) division of the Electrolux Group and the motor manufacturing assets of Jiangsu Changheng Group Co. Ltd. (Changheng). The total cost of these acquisitions was $25.0 million including future payments of $3.8 million and acquisition costs of $0.1 million and exceeded the fair value of the net assets acquired by $3.7 million which was recorded as non-deductible goodwill in the Electrical Products segment. Athens, based in Athens, Tennessee, is a manufacturer of hermetic motors for both scroll and reciprocating compressors. Changheng is located in the JiangSu province of China and manufactures air-moving motors principally for the Chinese air conditioning market. The respective purchase prices for the Athens and Changheng acquisitions were allocated to the assets acquired and liabilities assumed based upon current estimates of their respective fair values at the date of acquisition. The operating results of these companies have been included in the company's consolidated financial statements since the dates of acquisition. The pro forma effect of these acquisitions, individually and in the aggregate, would not be significant to 2002 or 2001 operating results. On December 28, 2001, the company acquired all of the outstanding stock of State Industries, Inc. (State). State is a manufacturer of residential and standard commercial water heaters and has nearly doubled the size of the company's base water heater business, while complementing the wholesale channel of distribution with a strong presence in the retail market. The aggregate purchase price of State was $117.6 million. This was comprised of $57.8 million for the outstanding stock, assumption of $56.3 million of debt, and $3.5 million of acquisition costs. The following table summarizes the estimated fair value of the assets acquired and liabilities assumed in connection with the State acquisition. The non-deductible goodwill has been recorded within the Water Systems segment. Of the $3.9 million of acquired intangible assets, $3.0 million was assigned to trademarks that are not subject to amortization. December 28, 2001 (dollars in thousands) - ----------------------------------------------------------------------------- Current assets $102,436 Property, plant and equipment 73,322 Other intangibles 3,890 Goodwill 63,682 Other assets 854 -------- Total assets acquired $244,184 ======== Current liabilities 74,969 Long-term liabilities 51,637 -------- Total liabilities assumed 126,606 -------- Net assets acquired $117,578 ======== On a pro forma basis, the unaudited consolidated results assuming the State acquisition occurred on January 1, 2001, is as follows: Year ended December 31, 2001 (dollars in thousands, except per share amounts) - ------------------------------------------------------------------------------ Net sales $1,467,261 Net earnings 17,604 Earnings per share: Basic .74 Diluted .74 28

2. Acquisitions (continued) The pro forma results have been prepared for informational purposes only and include adjustments to depreciation expense of acquired plant and equipment, amortization of intangible assets other than goodwill and trademarks, increased interest expense on acquisition debt, and certain other adjustments, together with related income tax effects of all such adjustments. Anticipated efficiencies from the consolidation of manufacturing and commercial activities and anticipated lower material costs related to the consolidation of purchasing have been excluded from the pro forma operating results. These pro forma results do not purport to be indicative of the results of operations that would have occurred had the acquisition been made as of the beginning of the period presented or of the results of operations that may occur in the future. In December 2001, the company acquired a 100 percent equity interest in Shenzhen Speeda Industries Co., Ltd. and is utilizing the facility located in China to manufacture C-frame electric motors. The total purchase price of $3.3 million, including future payments of $0.7 million, exceeded the fair value of the assets acquired (principally plant and equipment) by $0.8 million and was recorded as non-deductible goodwill within the Electrical Products segment. In connection with the acquisition of Athens, the company recorded purchase liabilities of $4.2 million primarily for employee severance costs associated with product manufacturing repositioning. As of December 31, 2002, $1.1 million has been charged against this reserve. In connection with the Athens acquisition and certain other acquisitions by the company, aggregate purchase liabilities of $26.5 million were recorded at the respective acquisition dates for employee severance and relocation, as well as certain facility exit costs. As of December 31, 2002, costs incurred and charged against these liabilities to date totaled $17.1 million. 3. Divestitures and Discontinued Operations On January 17, 2000 (the measurement date), the company, with the approval of its Board of Directors, decided to divest the company's fiberglass piping and liquid and dry storage businesses. The combined net sales of these operations were $129.3 million in 2000. On December 8, 2000, the company sold the fiberglass piping business, operated as Smith Fiberglass Products Company. On January 10, 2001, the company sold its liquid and dry storage business, operated as Engineered Storage Products Company. The net after-tax proceeds from the sale of these businesses were $62 million. The components of the after-tax loss from discontinued operations included in the consolidated statement of earnings are as follows: Year ended December 31, 2000 (dollars in thousands) - ------------------------------------------------------------------------------ Earnings from operations: Engineered Storage Products Company $ 3,139 Loss on disposition: Smith Fiberglass Products Company (9,032) Engineered Storage Products Company (1,993) Automotive Products Company (4,017) -------- Net after-tax loss from discontinued operations $(11,903) ======== Certain expenses have been allocated to the operations of the discontinued businesses, including interest expense, which was allocated based on the ratio of net assets of the discontinued businesses to the total consolidated capital of the company. The $9.0 million additional loss recorded at the time of the disposition of the fiberglass piping business in 2000 resulted from recognition of sales proceeds substantially less than originally anticipated, as the acquisition financing market, both generally and specific to the potential buyer, deteriorated to the point where the original transaction was not feasible. Subsequently, a sales contract containing a substantial reduction in sales proceeds and other concessions made by the company relative to the assumption of certain future costs was negotiated. 29

3. Divestitures and Discontinued Operations (continued) An after-tax loss from operations (in an amount greater than what was originally anticipated as of the measurement date) of $0.5 million is included in the $9.0 million loss on disposition in 2000. As a result of difficult financing conditions prevalent late in 2000, certain prospective buyers for the storage business withdrew from active negotiations resulting in a single interested buyer. The company agreed to price concessions to successfully complete its exit from this business and resulted in an unanticipated after-tax loss on disposition for this business of $2.0 million. The $4.0 million after-tax loss on disposition for the automotive business consists of two items: $2.8 million ($4.0 million pretax) for workers compensation costs associated with increased claims having an occurrence date prior to the 1997 sale of the automotive business for which the company retained responsibility per the sales contract; and $1.2 million ($2.0 million pretax) for final settlement of a purchase price dispute in the amount of $7.6 million for which a $5.6 million pretax reserve had been established at the time of sale. The $2.8 million adjustment for workers compensation costs was incremental to a $12.3 million reserve for workers compensation retained by the company at the time of sale. Included in the consolidated balance sheet at December 31, 2002, are net current liabilities of $1.6 million and net long-term liabilities of $1.7 million. Included in the consolidated balance sheet at December 31, 2001, are net current assets of $1.8 million and net long-term liabilities of $2.1 million. 4. Business Improvement Programs In the fourth quarter of 2001, the company recorded restructuring and other charges of $9.4 million ($6.0 million after-tax, or $.25 per share). The charges include employee separation costs of $7.7 million associated with product or component manufacturing repositioning and the realignment of certain administrative functions. The resulting reduction of workforce is expected to approximate 150 salaried and 775 hourly employees. In addition, the company recorded facility impairment and lease charges of $1.7 million representing estimated costs of facilities to be vacated. The company spent $2.9 million through December 31, 2002, for employee severance and separation costs. At December 31, 2002, the company estimates approximately 500 employees are yet to be impacted and plans to be substantially completed with the business improvement activities prior to December 31, 2003. 5.

Goodwill In connection with the adoption of SFAS No. 142, the company completed the first step of the transitional goodwill impairment test, which required the company to compare the fair value of its reporting units to the carrying value of the net assets of the respective reporting units as of January 1, 2002. Based on this analysis, the company concluded that no impairment existed at the time of adoption, and, accordingly, the company has not recognized any transitional impairment loss. Additionally, the company concluded that no impairment existed at the time of the annual impairment test which was performed in the fourth quarter. Changes in the carrying amount of goodwill during the year ended December 31, 2002, consist of the following: Electrical Water (dollars in thousands) Products Systems Total - ------------------------------------------------------------------------------------------- Balance at December 31, 2001 $230,004 $65,069 $295,073 Acquisition of businesses (see Note 2) 3,728 - 3,728 Adjustment to finalize 2001 acquisitions 50 3,559 3,609 -------- ------- -------- Balance at December 31, 2002 $233,782 $68,628 $302,410 ======== ======= ======== 31

It also has a $82.5 million 364-day credit agreement with a group of six banks, which expires on July 25, 2003. At its option, the company maintains either cash balances or pays fees for bank credit and services. The company's credit agreements and term notes contain certain conditions and provisions which restrict the company's payment of dividends. Under the most restrictive of these provisions, retained earnings of $92 million were unrestricted as of December 31, 2002. 32

9. Long-Term Debt and Lease Commitments (continued) Borrowings under the bank credit lines and in the commercial paper market that are supported by the multi-year revolving credit agreement have been classified as long-term. It has been the company's practice to renew or replace the revolving credit agreement so as to maintain the availability of debt on a long-term basis and to provide 100 percent backup for its borrowings in the commercial paper market. Scheduled maturities of long-term debt within each of the five years subsequent to December 31, 2002, is as follows: 2003-$11.7; 2004-$8.6; 2005-$8.6; 2006-$6.9; 2007-$6.9 million. Future minimum payments under noncancelable operating leases total $66.3 million and are due as follows: 2003-$14.3; 2004-$12.1; 2005-$8.8; 2006-$6.8; 2007-$6.0 and thereafter - $18.3 million. Rent expense including payments under operating leases, was $22.0, $19.0, and $18.3 million in 2002, 2001, and 2000, respectively. Interest paid by the company for continuing and discontinued operations, was $13.9, $16.9, and $24.6 million in 2002, 2001, and 2000, respectively. 10. Stockholders' Equity The company's authorized capital consists of 3 million shares of Preferred Stock $1 par value, 14 million shares of Class A Common Stock $5 par value, and 60 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 25 percent of the Board of Directors and has 1/10th vote per share on all other matters. On May 10, 2002, the company completed the sale of 4,776,065 shares of Common Stock held in treasury. The $127.5 million net proceeds from the offering were used to reduce long-term debt. During 2002, 2001, and 2000, 91,049, 36,236, and 200 shares, respectively, of Class A Common Stock were converted into Common Stock. Regular dividends paid on the Class A Common Stock and Common Stock amounted to $.54, $.52, and $.50 per share in 2002, 2001, and 2000, respectively. At December 31, 2002, 32,595 and 3,476,844, shares of Class A Common Stock and Common Stock, respectively, were held as treasury stock. At December 31, 2001, 32,595 and 8,730,594 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 thousands) 2002 2001 - ----------------------------------------------------------------------------------------- Foreign currency translation adjustments $ (3,340) $(6,419) Unrealized net loss on cash flow derivative instruments (3,797) (439) Additional minimum pension liability (114,740) - --------- ------- $(121,877) $(6,858) ========= ======= 33

11. Stock Options The company adopted the A. O. Smith Combined Executive Incentive Compensation Plan (the "plan") effective January 1, 2002. The plan supercedes and replaces two predecessor incentive compensation plans. The plan provides for the issuance of 1.5 million stock options at exercise prices equal to the fair value of Common Stock on the date of grant. Additionally, any shares that would have been available for stock option grants under either of the predecessor plans, if such plans were in effect, will be available for granting of stock option awards under the plan. The options granted become exercisable one year from date of grant and, for active employees, expire ten years after date of grant. The number of shares available for granting of options at December 31, 2002, was 1,325,850. Participants may also be awarded shares of restricted stock under the plan. In 2002, the company granted 49,000 shares of restricted common stock under the plan. The restricted shares were valued at $1.3 million at the date of issuance and will be recognized as compensation expense ratably over the three-year vesting period. Compensation expense of $0.1 million was recognized in 2002. Changes in option shares, all of which are Common Stock, were as follows: Weighted- Average Per Share Years Ended December 31 Exercise --------------------------------------------------- Price 2002 2001 2000 --------- ---- ---- ---- Outstanding at beginning of year $17.01 2,733,600 2,448,500 1,979,800 Granted 2002--$26.88 per share 26.88 296,400 2001--$15.14 per share 510,700 2000--$13.56 to $16.28 per share 632,000 Exercised 2002--$8.67 to $18.33 per share 13.92 (432,400) 2001--$5.63 to $16.33 per share (225,600) 2000--$4.67 to $16.33 per share (141,600) Expired 2002--$27.25 to $29.03 per share 28.14 (12,600) - - 2000--$18.00 to $27.25 per share - - (21,700) --------- --------- --------- Outstanding at end of year (2002--$13.56 to $29.03 per share) 18.54 2,585,000 2,733,600 2,448,500 ========= ========= ========= Exercisable at end of year 17.46 2,288,600 2,222,900 1,816,500 ========= ========= ========= 34

Assumptions were as follows: 2002 2001 2000 - ------------------------------------------------------------------------------ Expected life (years) 6.3 6.0 5.0 Risk-free interest rate 3.3% 4.7% 5.0% Dividend yield 2.2% 2.3% 2.2% Expected volatility 41.3% 37.9% 39.9% 12. Pension and Other Post-retirement Benefits The company provides retirement benefits for all United States employees. Plan assets consist primarily of marketable equities and debt securities. The company also has several foreign pension plans, none of which are material to the company's financial position. Effective January 1, 2001, the company changed its Executive Supplemental Pension Plan (ESPP) to an unfunded defined-benefit plan. The company has a defined-contribution profit sharing and retirement plan covering the majority of its salaried nonunion employees which provides for annual company contributions of 35 percent to 140 percent of qualifying contributions made by participating employees. The amount of the company's contribution in excess of 35 percent is dependent upon the company's profitability. The company also has defined-contribution plans for certain hourly employees which provide for annual matching company contributions. On December 28, 2001, the company acquired State, including its pension and defined-contribution benefit plans. The company has several 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 a result, a one percentage point change in the health care cost trend rate would not have a significant effect on the amounts reported. The post-retirement benefit obligation was determined using an assumed healthcare cost trend rate of eight percent in 2002 trending down to six percent in 2004 and thereafter. The following tables present the changes in benefit obligations, plan assets, funded status, and major assumptions used to determine these amounts for domestic pension and post-retirement plans and components of net periodic benefit costs. 35

The accumulated benefit obligations related to the company's pension plans exceeded the fair value of the plans' assets by $88,713 as of December 31, 2002. This under-funded status is primarily due to the impact of recent declines in the U.S. equity markets, which resulted in a drop in the fair value of pension assets; and declines in interest rates, which resulted in an increase in the present value of pension obligations. As a result of the under-funded status, the company recorded a charge to stockholders' equity of $114,740, representing the elimination of the prepaid pension asset, the establishment of a liability for under-funding, as well as the related deferred income tax impacts. This non-cash charge has no impact on income or cash flow. While declines in the equity markets and interest rates had a significant impact on the funded status of the plans, the pension plans continue to meet all funding requirements under ERISA regulations, and under current assumptions, no significant minimum funding requirement is expected for several years. 13. Income Taxes The components of the provision for income taxes consisted of the following: Years ended December 31 (dollars in thousands) 2002 2001 2000 - ---------------------------------------------------------------------------------------------------------------------- Current: Federal $ 4,802 $(10,100) $ 3,964 State 1,543 (12) 428 International 3,489 2,426 3,581 Deferred 17,211 15,670 15,459 ------- -------- ------- $27,045 $ 7,984 $23,432 ======= ======== ======= 37

13. Income Taxes (continued) The provision for income taxes differs from the U.S. federal statutory rate due to the following items: Years ended December 31 2002 2001 2000 - ---------------------------------------------------------------------------------------------------------------------- Provision at U.S. federal statutory rate 35.0 % 35.0 % 35.0 % State income and franchise taxes 3.5 (.8) 3.0 International income tax rate differential (2.3) 2.2 (1.1) Research tax credits (1.3) (1.3) (.1) Other (.4) .4 (.8) ---- ---- ---- 34.5 % 35.5 % 36.0 % ==== ==== ==== Components of earnings before income taxes were as follows: Years ended December 31 (dollars in thousands) 2002 2001 2000A - ---------------------------------------------------------------------------------------------------------------------- United States $63,468 $18,939 $57,845 International 14,922 3,547 7,243 ------- ------- ------- $78,390 $22,486 $65,088 ======= ======= ======= Total taxes paid (tax refunds received) by the company for continuing and discontinued operations amounted to $(10.6), $(2.7), and $13.1 million in 2002, 2001, and 2000, respectively. No provision for U.S. income taxes or foreign withholding taxes has been made on the undistributed earnings of foreign subsidiaries as such earnings are considered to be permanently invested. At December 31, 2002, the undistributed earnings amounted to $52.4 million. Determination of the amount of unrecognized deferred tax liability on the undistributed earnings is not practicable. In addition, no provision or benefit for U.S. income taxes have been made on foreign currency translation gains or losses. The tax effects of temporary differences of assets and liabilities between income tax and financial reporting are as follows: December 31 (dollars in thousands) - ------------------------------------------------------------------------------------------------------------------------ 2002 2001 ---------------------------------- ------------------------------------- Assets Liabilities Assets Liabilities ----------------------------------------------------------------------------- Employee benefits $ 52,242 $ - $25,605 $ 42,125 Inventory - 2,582 - 3,363 Recoverable dip tube costs - 13,262 - 12,941 Product liability and warranty 41,925 - 40,986 - Depreciation differences - 45,603 - 42,781 Amortization differences - 24,119 - 17,941 Tax loss and credit carryovers 6,770 - 9,946 - All other 3,831 - 2,863 - -------- ------- ------- -------- $104,768 $85,566 $79,400 $119,151 ======== ======= ======= ======== Net asset (liability) $ 19,202 $(39,751) ======== ======== 38

13. Income Taxes (continued) These deferred tax assets and liabilities are classified in the balance sheet as current or long-term based on the balance sheet classification of the related assets and liabilities as follows: December 31 (dollars in thousands) 2002 2001 - -------------------------------------------------------------------------------- Current deferred income tax assets $26,714 $ 22,403 Long-term deferred income tax liabilities (7,512) (62,154) ------- -------- Net asset (liability) $19,202 $(39,751) ======= ======== As a result of the acquisition of State, the company has $5.8 million of federal net operating loss carryovers that expire between 2018 and 2021, $7.6 million of federal capital loss carryovers that expire in 2006, $0.5 million of contribution carryovers that expire between 2003 and 2006, and $2.9 million of tax credits, the majority of which have an unlimited carryover period. Due to a change in State ownership, the annual limitation for utilization of the federal net operating loss carryovers is the equivalent of $2.2 million of deductions. The company also has approximately $125 million of state and local net operating loss carryovers. The majority of these carryovers expire between 2010 and 2022. 14. Litigation and Insurance Matters The company is involved in various unresolved legal actions, administrative proceedings, and claims in the ordinary course of its business involving product liability, property damage, insurance coverage, 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, the company believes these unresolved legal actions will not have a material effect on its financial position or results of operations. The following paragraphs summarize noteworthy actions and proceedings. In 1999, a class action lawsuit was filed in the United States District Court, Western District of Missouri, by individuals on behalf of themselves and all persons throughout the United States who have owned or currently own a water heater manufactured by Rheem Manufacturing Company, A. O. Smith Corporation, Bradford White Company, American Water Heater Company, Lochinvar Corporation, and State Industries, Inc. (the "water heater manufacturers") that contains a dip tube manufactured, designed, supplied, or sold by Perfection Corporation between August 1993 and October 1996. A dip tube is a plastic tube in a residential water heater that brings the cold water supply to the bottom area of the tank to be heated. The plaintiffs and the water heater manufacturers reached a settlement of this lawsuit which the court approved in 2000. The water heater manufacturers paid the settlement, and all other legal actions brought against the water heater manufacturers related to dip tube claims have been dismissed as a result of the settlement of the class action. Separately, the water heater manufacturers in late 1999 filed a direct action lawsuit in the Civil District Court for the Parish of Orleans, State of Louisiana, against Perfection Corporation and American Meter Company, the parent company of Perfection, Manner Plastics Materials, Inc., and their insurers. This lawsuit seeks (1) recovery of damages sustained by the water heater manufacturers related to the costs of the class action settlement and the handling of dip tube claims outside of and prior to the national class action settlement, (2) damages for the liability of the water heater manufacturers assumed by Perfection Corporation by contract, and (3) personal injuries suffered by the water heater manufacturers as a result of the disparagement of their businesses. Also relating to the water heater manufacturers' recovery efforts, the insurers of Perfection Corporation have brought third-party claims against the water heater manufacturers in a state court action in Cook County, Illinois. Perfection Corporation has also sued the water heater manufacturers in a separate action in Cook County, Illinois. The filing by Perfection Corporation is an attempt to preempt the Louisiana lawsuit. 39

14. Litigation and Insurance Matters (continued) As of December 31, 2002, the company recorded as a long-term receivable approximately $34.0 million (as detailed below) related to dip tube repair claims, administrative costs, legal fees, and related expenses. It is the company's expectation that all or a substantial portion of its costs will be recovered from Perfection, American Meter Company, Manner Plastics Materials, Inc. and their insurers, as well as the company's insurers. 2000 Cumulative (dollars in thousands) 2002 2001 and Prior December 31, 2002 - ------------------------------------------------------------------------------------------------------- Claim payments $ 53 $13,378 $ 8,805 $22,236 Administrative costs 19 4,503 3,030 7,552 Legal fees 1,173 470 2,575 4,218 ------ ------- ------- ------- $1,245 $18,351 $14,410 $34,006 ====== ======= ======= ======= The company is currently involved as a potentially responsible party (PRP) in judicial and administrative proceedings initiated on behalf of various state and federal regulatory agencies seeking to clean up 11 sites which have been environmentally impacted (the "sites") and to recover costs they have incurred or will incur as to the sites. The company previously reported that it was a defendant in two separate lawsuits involving a former mine in Colorado that is being remediated by the United States Environmental Protection Agency (EPA). The claims against the company have been dismissed by the trial court in both of those actions. The State of Colorado has appealed the trial court's decision in one of those actions, and the company believes that the trial court's well-reasoned decision will be upheld by the appellate court. Since the EPA has indicated that it does not intend to pursue any claims against the company with respect to this site, the company should have no further potential liability with respect to the site. It is impossible at this time to estimate the total cost of remediation for the sites or the company's ultimate share of those costs, primarily because the sites are in various stages of the remediation process and issues remain open at many sites concerning the selection and implementation of the final remedy, the cost of that remedy and the company's liability at a site relative to the liability and viability of the other PRPs. The company has established reserves for the sites in a manner that is consistent with accounting principles generally accepted in the United States for costs associated with such cleanups when those costs are capable of being reasonably estimated. To the best of the company's knowledge, the reserves it has established and insurance proceeds that are available to the company are sufficient to cover the company's liability. The company further believes its insurers have the financial ability to pay any such covered claims, and there are viable PRPs at each of the sites which have the financial ability to pay their respective shares of liability at the sites. With respect to non-environmental claims, the company has self-insured a portion of its product liability loss exposure and other business risks for many years. The company has established reserves which it believes are adequate to cover incurred claims. For the year ended December 31, 2002, the company (excluding State) had $125 million of third-party product liability insurance for individual losses in excess of $1.5 million and for aggregate annual losses in excess of $10 million; State had $125 million of third-party product liability insurance for individual losses in excess of $3.0 million and for aggregate annual losses in excess of $65 million.

15. Operations by Segment The company has two reportable segments: Electrical Products and Water Systems. The Electrical Products segment manufactures fractional horsepower alternating current (A/C) and direct current (D/C) and integral horsepower motors used in fans and blowers in furnaces, air conditioners, and ventilating systems; industrial applications such as material handling; as well as in other consumer products such as home appliances and pumps, swimming pools, hot tubs, and spas. In addition, the Electrical Products segment manufactures hermetic motors which are sold worldwide to manufacturers of compressors used in air conditioning and refrigeration systems. The Water Systems segment manufactures residential gas and electric water heaters as well as commercial water heating equipment used in a wide range of applications including hotels, laundries, car washes, factories, and large institutions. In addition, the Water Systems segment manufactures copper tube boilers used in large-volume hot water and hydronic heating applications. The accounting policies of the reportable segments are the same as those described in the "Summary of Significant Accounting Policies" outlined in Note 1. Intersegment sales have been excluded from segment revenues and are immaterial. Earnings before interest and taxes (EBIT) is used to measure the performance of the segments and allocate resources.
