ITEM 1 - BUSINESS

We are a leading manufacturer of water heating equipment and electric motors, serving a diverse mix of residential, commercial and industrial end markets principally in the United States with a growing international presence. Our company is comprised of two reporting segments: Water Products and Electrical Products. Our Water Products 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. Our Electrical Products business manufactures and markets a comprehensive line of hermetic motors, fractional horsepower alternating current (AC) and direct current (DC) motors. In 2008, we had net sales of approximately $2.3 billion, with 63 percent attributable to our Water Products business and 37 percent attributable to our Electrical Products business.

The following table summarizes our sales by reporting 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 in Item 8 in this document.

WATER PRODUCTS

In our Water Products business, sales increased 2 percent or $28 million in 2008 over the prior year. A 27 percent increase in sales of water heaters in China and increased pricing that partially covered higher raw material costs helped offset significantly lower residential volumes.

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 electric, natural gas and liquid propane models as well as solar booster tanks and gas tankless units for today’s energy efficient homes. North American residential water heater sales in 2008 were approximately $945 million or 65 percent of segment revenues.

Commercial (standard and specialty) water heaters. Our gas, oil and electric water heaters come in capacities ranging from 6 gallons to 600 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.

A significant portion of our Water Products business is derived from the replacement of existing product, and it is believed that the sale of product to the North American residential new housing construction market represents approximately 15 percent of the segment’s total residential water heater sales. Our Water Products business also manufactures copper-tube boilers and expansion tanks and related products and parts.

We are the largest manufacturer and marketer of water heaters in North America, and we have a leading share in both the residential and commercial segments of the market. In the commercial market segment, we believe our comprehensive product line, as well as our high-efficiency products, give us a competitive advantage in this higher-margin segment of the water heating industry. As the leader in the residential water heating market segment, we offer an extensive line of high-efficiency gas and electric models.

Our Water Products wholesale distribution channel includes more than 1,100 independent wholesale plumbing distributors with more than 4,600 selling locations serving residential, commercial and industrial markets. We also sell our residential

water heaters through the retail channel. In this channel, our customers include five of the seven largest national hardware and home center chains, including long-standing private label relationships with both Lowes and Sears, Roebuck and Co.

We entered the Chinese water heater market through a joint venture in 1995, buying out our partner three years later. Since that time, we have been aggressively expanding our presence while building brand recognition in the Chinese residential and commercial markets. In 2008, the company generated sales of $187 million in China, an increase of 27 percent, compared with 2007. We believe we are one of the top two suppliers of water heaters to the residential market in China.

In 2008, we entered the India market by importing units specifically designed for India from our Nanjing, China facility. We established a sales office and started the land acquisition process for a manufacturing plant near Bangalore, India. We expect to begin manufacturing water heaters in India in the second quarter of 2010.

We sell our water heating products in highly competitive markets. We compete in each of our targeted market segments based on product design, quality of products and services, performance and price. Our principal domestic water heating competitors include Rheem Manufacturing Company, Inc., Bradford-White Corporation and Lochinvar Corporation. Our primary competitor in China is Haier Appliances, a Chinese company, but we also compete with Ariston, Siemens and Midea in the electric water heater market and Rinnai and Noritz in the gas instantaneous water heater market. Additionally, we compete with numerous other Chinese private and state-owned water heater and boiler manufacturing companies.

ELECTRICAL PRODUCTS

In our Electrical Products business, volume declines more than offset higher prices related to higher raw material costs. Sales in the segment declined four percent in 2008, or approximately $36 million, to $858 million compared with 2007. Unit volume sales were negatively impacted by the weak housing market and customer inventory reductions at the end of the year.

We are one of the four largest manufacturers of electric motors in North America. 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 1,320 horsepower hermetic and 400 horsepower integral motors. We believe our extensive product offerings give us an advantage in our targeted markets, allowing us to serve a wide range of our customer’s electric motor needs.

Our motors are used in a wide range of targeted residential and commercial 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 North American Original Equipment Manufacturers (OEM) heating, ventilating, air conditioning and refrigeration market account for approximately 33 percent of segment sales. Approximately 80 percent of our 2008 segment sales were to OEMs in a diverse mix of industries, with the remainder of sales sold through aftermarket or distribution channels. We believe that at least 25 percent of our total segment sales were attributable to products used outside of the United States. A significant portion of our Electrical Products business is derived from the replacement of existing product, and it is believed that the sale of product to the residential new housing construction market in North America represents approximately 25 percent of the segment’s total sales.

To remain a leader in this highly competitive industry, we are committed to being a low-cost supplier of electric motors. Since 2001, we have undertaken initiatives to accelerate cost-reduction in our motor operations to enhance our competitive position. These initiatives included the closure of nine U.S. facilities as well as our operations in Budapest, Hungary; Bray, Ireland; and Taizhou, China, transferring the majority of related production to our lower cost operations in Mexico and China.

At the end of the third quarter of 2007, we announced that we would close our operations in Scottsville, KY, and Mebane, NC, and consolidate our hermetic motor assembly operations in Acuna, Mexico and Suzhou, China. We transferred the work at both hermetic motor facilities in the fourth quarter of 2008. In addition we also announced the closing of our motor manufacturing facility in Budapest, Hungary, and transfer of the remaining production to China. For all of 2007, the restructuring expense at Electrical Products totaled $22.8 million before taxes or $8.9 million after taxes, equivalent to $.29 per share. Included in the 2007 after tax amount was a $9.9 million tax benefit associated with the write-off of the investment in our Hungarian subsidiary. In 2008, we recorded an additional pretax restructuring charge of approximately $8.7 million associated with the three plant closings mentioned above and repositioning at Juarez, Mexico equivalent to $5.3 million after taxes, or approximately $.18 per share.

In November of 2005, we completed our fourth motor acquisition in China with the purchase of Yueyang Zhongmin Special Electrical Machinery Co., Ltd. (Yueyang). Located in Hunan Province, Yueyang manufactures large hermetic motors used in commercial air conditioning applications.

We sell our electric motor products in highly competitive markets. We compete in each of our targeted market segments based on product design, quality of products and services, performance and price. Our principal competitors in the electric motor industry are Emerson Electric Co., Regal Beloit Corporation and Baldor Electric Company.

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 typically hedge a portion of our annual copper and aluminum purchases to protect against price volatility. In addition a portion of Electrical Products customers are contractually obligated to accept price changes based on fluctuations in certain of our raw material prices. Global demand pressures have also resulted in significant volatility in steel, copper and aluminum costs.

RESEARCH AND DEVELOPMENT

In order to improve competitiveness by generating new products and processes, we conduct research and development at our Corporate Technology Center in Milwaukee, Wisconsin and at our operating units. Total expenditures for research and development in 2008, 2007 and 2006 were $48.5, $47.8 and $42.3 million, respectively.

PATENTS AND TRADEMARKS

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 believe that our business as a whole is materially dependent upon any such trademark, trade name, patent, trade secret or license.

EMPLOYEES

Our company and its subsidiaries employed approximately 15,350 employees as of December 31, 2008.

BACKLOG

Due to the short-cycle nature of our businesses, 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 and is not expected to have a material effect upon the capital expenditures, earnings, or competitive position of our company. See Item 3.

ITEM 1A – RISK FACTORS

You should carefully consider the risk factors set forth below and all other information contained in this Annual Report on Form 10-K, including the documents incorporated by reference, before making an investment decision regarding our common stock. If any of the events contemplated by the following risks actually occurs, then our business, financial condition, or results of operations could be materially adversely affected. As a result, the trading price of our common stock could decline, and you may lose all or part of your investment. The risks and uncertainties below are not the only risks facing our company.

•

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

The U.S. economy is currently in a recession and it has now spread to other geographic areas in which we operate. The global credit and capital markets troubles threaten to extend the depth and duration of the recession. A continuation or deepening of the global economic downturn 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, and slower adoption of energy efficient products which could negatively impact our profitability and/or cash flow. In addition, the current economic conditions, including the 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, and increased material prices, which could negatively impact our ability to distribute, market and sell our products and our financial condition, results of operations and cash flows.

•

A portion of our business could be adversely affected by a decline in new residential or commercial construction

We sell a portion of our products for new residential and commercial construction. The strength of these markets depends on new housing starts and business investment, which are a function of many factors beyond our control, including interest rates, employment levels, availability of credit and consumer confidence. Further downturns in the new construction markets we serve could result in lower revenues and lower profitability. New housing starts declined in 2007 and 2008 and may continue at the lower levels or decline further. Commercial construction activity, which has been high in recent years, could continue the decline that began in the second half of 2008. We believe that approximately 15 percent of our Water Products and 25 percent of our Electrical Products businesses, respectively, are affected by changes in the residential housing construction markets. Furthermore, though we believe that the majority of the commercial business we serve is for replacement, we could also be affected by changes in the commercial construction market.

•

A portion of our business could be affected by a slowing Chinese economy

We have experienced above average growth in sales in China for both our Water Products and Electrical Products segments. If the Chinese economy were to experience a significant slowdown 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 four largest customers represented approximately 26 percent of 2008 net sales. We expect that customer concentration will continue for the foreseeable future in light of the global economic downturn. Our dependence on sales from 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 in the future shift their

purchases of products to our competitors or to other sources. The loss of one or more of our largest customers, any material reduction or delay in sales to these customers, our inability to successfully develop relationships with additional customers, or our inability to execute on pricing actions could have a material adverse effect on our financial position, results of operations and cash flows.

•

Because we participate in markets that are highly competitive, our revenues 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, quality of products and services, product performance, maintenance costs and price. We compete against manufacturers located in the United States and throughout the world. We also face potential competition from some OEMs to whom we sell our electrical products and from our customers and the end users of our products, who continually assess any costs that could be reduced by vertically integrating or using alternate sources for the products we manufacture. Some of our competitors may have greater financial, marketing, manufacturing, and distribution resources than we have. 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.

•

We increasingly manufacture our products outside the United States, which may present additional risks to our business

A significant portion of our 2008 net sales were attributable to products manufactured outside of the United States, principally in Mexico and China. Approximately 5,700 of our 15,350 total employees and 14 of our 35 manufacturing facilities are located in Mexico. Approximately 4,500 employees and five manufacturing facilities are located in China. International operations generally are subject to various risks, including political, religious, and economic instability, local labor market conditions, the imposition of foreign tariffs and other trade restrictions, the impact of foreign government regulations, and the effects of income and withholding tax, governmental expropriation, and differences in business practices. We may incur increased costs and experience delays or disruptions in product deliveries and payments in connection with international manufacturing and sales that could cause loss of revenue. Unfavorable changes in the political, regulatory, and business climate could have a material adverse effect on our financial condition, results of operations and cash flows.

•

In serving U.S. customers of our electric motors business, we manufacture a significant portion of our products in Mexico and China, which exposes us to the risk of increased labor costs due to both wage inflation in Mexico and stability or increases in the value of the Mexican peso and Chinese RMB relative to the U.S. dollar

Almost all of our electric motor manufacturing productive labor hours are incurred in Mexico and China. The peso based costs we incur manufacturing these products are directly related to changes in labor costs in Mexico and fluctuations in exchange rates of the Mexican peso relative to the U.S. dollar. The labor costs we incur are measured in U.S. dollars and based on the cost of labor in Mexican pesos. Historically, Mexico has had higher wage inflation than the United States. That inflation does not adversely affect our costs when there is a corresponding decrease in the value of the Mexican peso relative to the U.S. dollar. However, during periods in which the value of the Mexican peso increases or remains stable relative to the U.S. dollar, higher wage inflation in Mexico results in an increase in our labor costs. Manufacturing and material costs we incur in China are principally incurred in Chinese RMB. If the RMB continues to strengthen against the U.S. dollar, our costs would increase.

•

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

The market price for certain key materials we purchase (e.g., steel, copper, aluminum, diesel fuel and natural gas) have been very volatile in the recent past. While our company periodically enters into futures contracts to fix the cost of certain raw material purchases, principally copper and aluminum, 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 any customer recovery of increased material costs which could negatively impact our profitability. As of December 31, 2008 the company had entered into commodity and foreign exchange contracts that totaled losses of $71 million. Even though a portion of these losses can contractually be passed on to customers the remaining amount could lead to lower operating earnings if we are unable to recover these costs from customers or because of reduced sales we are unable to use the materials or foreign currency. In addition, in some cases we are dependent on a single or limited number of suppliers for some of the raw materials and

components required in the manufacture of our product. A significant disruption or termination of the supply from one of these suppliers could delay sales or increase cost which could result in 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 negative investment returns in 2008, the projected benefit obligations of our defined benefit pension plans exceeded the fair value of the plan assets by $264 million at December 31, 2008. Beginning in 2008, the minimum required contribution equals the target normal cost plus a seven year amortization of any funding shortfall, offset by any ERISA credit balance. As the company could utilize its credit balance, the required contribution in 2009 is approximately $18 million, however the company is forecasting contributions of between $18 to $35 million and $40 to $50 million in 2009 and 2010, respectively. Among the key assumptions inherent in the 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 flow from operations to making the contributions which could negatively impact our flexibility in managing the company.

•

We have significant goodwill and an impairment of our goodwill could cause a decline in our net worth

Our total assets include significant goodwill. The goodwill results from our acquisitions, representing the excess of the purchase price we paid over the fair value of the tangible and intangible assets we acquired. We assess whether there has been impairment in the value of our goodwill during the fourth quarter of each calendar year or sooner if triggering events warrant. If future operating performance at one or more of our businesses does not meet expectations, we may be required to reflect, under current applicable accounting rules, a non-cash charge to operating results for goodwill impairment. The recognition of an impairment of a significant portion of goodwill 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 may affect our ability to maintain the required debt-to-capital ratio existing under our 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.

•

A substantial contribution to our financial results has come through acquisitions, and we may not be able to identify or complete future acquisitions, which could adversely affect our future growth

Acquisitions we have made since 1997 have had a significant impact on our results of operations. While we will continue to evaluate potential acquisitions, we may not be able to identify and successfully negotiate suitable acquisitions, obtain financing for future acquisitions on satisfactory terms, utilize cash flow from operations, obtain regulatory approval for certain acquisitions, or otherwise complete acquisitions in the future. 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. 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. We cannot assure you that future acquisitions will not have a material adverse affect 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 water heater and electric motor products expose us to potential product liability risks that are inherent in the design, manufacture, and sale of our products. While we currently maintain what we believe to be suitable product liability insurance, we cannot assure you 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 successfully weather the current economic downturn. In addition, we self-insure a portion of product liability claims. A series of successful claims against us could materially and adversely affect our reputation and our financial condition, results of operations and cash flows.

•

Our credit facility expires in February 2011 and the terms of its replacement will be based on prevailing lending conditions when it is replaced

In addition to issuing commercial paper and utilizing short term credit lines, we rely on our $425 million revolving credit facility to support our daily operations. The global credit markets tightened considerably in 2008. If these conditions remain unchanged or worsen, our replacement credit facility may have less favorable terms than the facility we have now. In particular, the new facility could have higher borrowing costs and more restrictive covenants. And, depending on banks willingness to lend, the facility could be smaller in size. A credit facility with less favorable terms could have a material adverse effect on our liquidity, financial condition, results of operations and cash flow.

•

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. These include energy efficiency, climate emissions, labeling and safety-related requirements. While we believe our products are currently some of the most efficient, safest, and environment-friendly products available, a significant change to these regulatory requirements, whether federal, state or local, or otherwise 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.

•

Currently, one stockholder has voting control of the company

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 25 percent of our board of directors. The holders of Class A Common Stock are entitled, as a class, to elect the remaining directors. As of December 31, 2008, Smith Investment Company (Smith Investment) effectively controlled the right to elect 70 percent of our board of directors (7 of 10) because it beneficially owned approximately 98 percent of our Class A Common Stock. As of December 31, 2008, Smith Investment beneficially owned approximately 32 percent of the total number of outstanding shares of our Common Stock and Class A Common Stock. Due to the differences in the voting rights between shares of our Common Stock and shares of our Class A Common Stock, Smith Investment 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. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Other Matters – Smith Investment Company Transaction” for a description of a proposed merger pursuant to which Smith Investment would become our subsidiary and a description of certain proposed amendments to our certificate of incorporation that stockholders will consider and that Smith Investment has committed to vote to approve. However, assuming such merger is completed, certain members of the founding family of our company and trusts for their benefit (Smith Family) are likely to have the ability to influence all matters requiring stockholder approval as described in more detail below. The differences in the voting rights between shares of our Common Stock and our Class A Common Stock could have the effect of delaying, deterring, or preventing a change of control.

•

Certain members of the founding family of our company and trusts for their benefit are likely to have the ability to influence all matters requiring stockholder approval

The merger agreement pursuant to which Smith Investment would become our subsidiary contemplates that certain members of the founding family of our company and trusts for their benefit (Smith Family) may enter into a voting trust agreement following the completion of the merger with respect to shares of our Class A Common Stock and shares of our Common Stock they receive in the merger. After giving effect to the merger, these members of the Smith Family are expected to own approximately 41.4% 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 51.6% of the voting power of the outstanding shares of our Class A Common Stock, as a separate class. 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. Accordingly, after the merger, the Smith Family members who enter into the voting trust agreement would collectively have the ability to influence the election of our Class A directors and other matters requiring stockholder approval in the same manner that Smith Investment can currently influence such matters. 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 may have the ability to maintain their collective voting rights in our company even if certain members of the Smith Family decide to transfer their shares.

ITEM 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 these matters appears in Note 13 of Notes to Consolidated Financial Statements.

ITEM 7 - MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

LIQUIDITY AND CAPITAL RESOURCES

We achieved net earnings of $81.9 million or $2.70 per share in 2008, compared with $88.2 million or $2.85 per share in 2007 and $76.5 million or $2.47 per share in 2006. Net earnings recorded in 2008 were lower than 2007 due to lower sales of U. S. residential product, higher raw material costs only partially offset by price increases, higher product warranty costs at our Water Products segment primarily as a result of higher steel costs and a higher tax rate. These factors were partially offset by lower restructuring costs in our Electrical Products segment, another strong year for our China water heater business, and lower product liability costs in our water heater business. Net earnings recorded in 2007 were higher than 2006 due to a full year of the GSW business acquired in April 2006, higher sales of commercial product, solid growth at our China water heater operation and a lower effective tax rate. These improvements were partially offset by higher SG&A expenses and restructuring charges in 2007 compared with 2006. Our individual segment performance will be discussed later in this section.

Our working capital was $276.3 million at December 31, 2008 compared with $295.0 million and $322.7 million at December 31, 2007 and December 31, 2006, respectively. The $18.7 million reduction in our working capital in 2008 compared with 2007 resulted from the recognition of a non-cash $73.0 million liability for derivative contracts and lower accounts receivable balances at both businesses related to volume declines, which were partially offset by higher inventories and lower accounts payable balances at our Electrical Products segment and cash deposits of $22.5 million associated with derivative contracts. The $27.7 million reduction in our working capital in 2007 compared with 2006 was a result of lower inventories in our Electrical Products segment. Higher accounts payable balances in both businesses were offset by an increase in our Water Products segment’s accounts receivable balances.

Cash provided by operating activities during 2008 was $106.6 million compared with $190.5 million during 2007 and $128.8 million during 2006. Lower net earnings in 2008 compared with 2007 and the changes in cash-related working capital accounts described above explain the majority of the decline. Higher net earnings in 2007 compared with 2006 combined with higher depreciation and amortization and the working capital decrease described above explain the $61.7 million year over year improvement in our cash flow. We expect cash provided by operating activities to be between $140 and $160 million in 2009.

Our capital expenditures were $66.1 million in 2008, lower than the $71.4 million spent in 2007. Our capital spending in 2006 was $68.2 million. We are projecting 2009 capital expenditures of between $75 and $85 million and 2009 depreciation and amortization of approximately $70 million. 2009 capital spending includes the construction of the water heater manufacturing plant near Bangalore, India and the completion of the expansion of our Nanjing, China water heater operations.

In February 2006, we completed a $425 million multi-currency five year revolving credit facility with a group of eight banks. The facility has an accordion provision which allows it to be increased up to $500 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 during all of calendar year 2008.

The facility backs up commercial paper and credit line borrowings, and it expires on February 17, 2011. As a result of the long-term nature of this facility, the commercial paper and credit line borrowings, as well as drawings under the facility are classified as long-term debt. At December 31, 2008, we had available borrowing capacity of $246.9 million under this facility. 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.

At this point in time, our liquidity has not been materially impacted by the current credit environment, and we do not expect that it will be materially impacted in the near future. There can be no assurance however, that the cost of future borrowings on our credit facilities will not be impacted by the ongoing capital market disruptions.

Our total debt was $334.8 million at the end of December 2008 compared with $395.2 million at the end of 2007. Our leverage, as measured by the ratio of total debt to total capitalization, was 34 percent at the end of 2008 the same as at the end of 2007.

Aggregate Contractual Obligations

A summary of our contractual obligations as of December 31, 2008, is as follows:


(dollars in millions)			Payments due by period
Contractual Obligations	Total		Less Than 1 year		1 - 3 Years		3 - 5 Years		More than 5 years
Long-term Debt	$	334.8	$	17.5	$	217.8	$	43.7	$	55.8
Fixed Rate Interest		36.3		8.3		13.0		8.4		6.6
Operating Leases		48.5		14.0		17.1		6.7		10.7
Purchase Obligations		87.7		87.7		-		-		-
Other Liabilities:
Commodity futures contracts		52.1		48.9		3.2		-		-
Foreign currency forward contracts		19.1		18.8		0.3		-		-

Total	$	578.5	$	195.2	$	251.4	$	58.8	$	73.1

As of December 31, 2008, the liability for uncertain income tax positions was $5.5 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 the company’s scheduled unit production. The purchase obligation amount presented above represents the value of commitments considered firm. The amounts in the table above for commodity and foreign currency contracts represent the costs to liquidate the contracts as of December 31, 2008.

GSW operated a captive insurance company to provide product liability and general liability insurance to its subsidiary, American Water Heater Company (American). We decided to cover American’s liability exposures with our existing insurance programs and operate the captive in runoff effective July 1, 2006. The reinsurance company restricts the amount of capital which must be maintained by the captive. At December 31, 2008, the restricted amount was $26.3 million compared with $38.9 million at the end of 2007 and is included in other non-current assets. The restricted assets are invested in money market securities.

In February 2007, our board of directors approved a stock repurchase program in the amount of one million shares of our common stock. During 2007, we completed the repurchase of all one million shares at an average cost of $36.62 per share. Our board approved an additional one million shares to be repurchased under this program at its December 2007 meeting. As of December 31, 2008, we have not repurchased any shares under the authorization approved in December 2007.

Our pension plan continues to meet all funding requirements under ERISA regulations. While we were not required to make a contribution to the plan in 2008, we elected to make a contribution of $17.3 million. We are required to make a contribution of approximately $18 million in 2009. The company is forecasting contributions to the pension plan to be between $18 and $35 million in 2009 and between $40 and $50 million in 2010. For further information on our pension plan, see Note 11 of the Notes to Consolidated Financial Statements.

We have paid dividends for 69 consecutive years with payments increasing each of the last 17 years. We paid total dividends of $.74 per share in 2008 compared with $.70 per share in 2007.

RESULTS OF OPERATIONS

Our sales in 2008 were $2.3 billion, about equal to sales in 2007 as a $28.2 million increase in sales in our Water Products segment was more than offset by a $35.9 million decline in sales in our Electrical Products segment. The higher Water Products sales were due mostly to increased sales in China and material related price increases which were partially offset by significantly lower residential volume. The decline at Electrical Products resulted primarily from lower unit volumes associated with the weak housing market. Sales in 2007 were $2.31 billion, an increase of $150.8 million or 7.0 percent from sales of $2.16 billion in 2006. The sales increase occurred in our Water Products segment and was due to a full year of the GSW business acquired in April 2006, which added $128 million of sales in the first quarter of 2007 as well as increased sales

of commercial water heaters and higher sales in China. Sales for Electrical Products declined $11.9 million from $905.9 million in 2006 to $894.0 million in 2007 as improved pricing was more than offset by lower volume.

Our gross profit margin for 2008 was 21.6 percent compared to 22.2 percent in 2007 as increased margins at Electrical Products were more than offset by lower margins at Water Products. The higher margins at Electrical Products resulted from commercial contract improvements, including pricing, at targeted accounts and repositioning savings. The lower margins at Water Products were caused by higher raw material costs, primarily steel, and its related effect on warranty costs which were partially offset by improvements in pricing. Our gross profit margin for 2006 was 21.5 percent. The improved margins in 2007 were due mostly to sales of higher margin products in our Water Products segment.

Selling, general and administrative expense (SG&A) was $5.6 million lower in 2008 than in 2007 as lower product liability expense primarily associated with an adverse verdict in 2007 at Water Products and lower bad debt provisions at both our product operations more than offset higher SG&A in support of increased sales at our China water heater operation. The increase in SG&A of $39.0 million from 2006 to 2007 was due to higher selling and advertising costs to support increased sales at our water heater segment and included $15.2 million of first quarter SG&A attributable to the GSW acquisition.

Pension expense in 2008 was $4.0 million compared to $12.2 million in 2007 and $11.9 million in 2006. The decrease in pension expense from 2007 to 2008 was due to an increase in the discount rate, lower amortization of deferred asset losses, and the absence of curtailment and other charges of $1.1 million. The increase in pension expense from 2006 to 2007 was due to curtailment and other charges as partially offset by lower amortization of deferred asset losses.

Pretax restructuring charges were $9.2 million, $24.7 million and $9.6 million in 2008, 2007 and 2006, respectively. The majority of the charges incurred in 2008, consisting primarily of severance and asset impairment, were associated with the plant closures initiated by our Electrical Products segment in 2007 and completed in 2008. In 2007, $22.8 million of restructuring expense was recognized by Electrical Products with $12.0 million of the charge attributed to the closing of our operations in Scottsville, KY and Mebane, NC and the write down of other assets. The closing of these plants resulted in our hermetic motor assembly operations being consolidated in Acuna, Mexico and Suzhou, China. A pretax charge of $9.2 million associated with the closing of our motor facility in Budapest, Hungary was also included in the 2007 charge. A pretax charge of $1.6 million was also included in the 2007 Electrical Products charge for certain other domestic repositioning and asset write down expenses. In addition to the 2007 restructuring charges at Electrical Products we also recognized a $1.9 million corporate charge related to a previously owned business. In 2006, $8.9 million of the $9.6 million restructuring charge was recognized by Electrical Products, most of which was related to the closure of our McMinnville, TN motor fabrication plant completed in the first quarter of 2007 and the closure of our motor operation in Taizhou, China in the fourth quarter of 2006. We do not have any current restructuring plans.

Interest expense decreased from $26.7 million in 2007 to $19.2 million in 2008 as a result of lower interest rates and debt. Interest expense increased from $24.9 million in 2006 to $26.7 million in 2007 due to GSW acquisition related financing costs incurred for a full year in 2007 versus only nine months in 2006.

In 2008 net other expense of $1.6 million compared to net other income of $0.9 million. The $2.5 million differential is due to $1.0 million lower interest income on restricted marketable securities due to liquidation of $12.0 million of short-term securities in the second quarter of 2008 with the remainder due to exchange losses as foreign currencies strengthened against the U.S. dollar. In 2007 net other income of $0.9 million compared to net other expense of $0.6 million in 2006. The differential was due to $0.5 million of interest income on restricted marketable securities in the first quarter of 2007 with the remainder due to exchange gains associated with U.S. dollar purchases made by our Canadian operations.

Our effective tax rate was 25.4 percent in 2008, 11.7 percent in 2007 and 27.3 percent in 2006. The 2007 effective rate included a $3.7 million tax benefit upon completion of tax audits and lapse of statutes of limitations and a $1.1 million China investment incentive tax benefit. Also included in the 2007 rate is a $9.9 million tax benefit associated with the write-off of the investment in our Hungarian subsidiary.

Our 2008 net earnings were $81.9 million or $2.70 per share compared with $88.2 million or $2.85 per share in 2007 and $76.5 million or $2.47 per share in 2006.

Water Products

Sales for our Water Products segment were $1.45 billion in 2008, a modest increase over sales of $1.42 billion in 2007. Sales at our China water heater operation increased by $40.1 million in 2008. Despite price increases to compensate for higher material costs, sales for residential water heaters were significantly lower in 2008 and partially offset the growth in China. Sales in 2007 were $162.3 million higher than sales of $1.26 billion in 2006. The increase was due to a full year of the GSW business acquired in April 2006, which added $128.0 million of sales in the first quarter of 2007, a $30.1 million increase in sales at our China operation and increased sales of commercial water heaters.

Operating earnings for Water Products were $134.7 million in 2008 or 10.2 percent lower than earnings of $150.0 million in 2007. The impact of growth in China and lower SG&A was more than offset by lower residential volume and higher costs for raw materials and components which were not recovered with price increases. Operating earnings of $150.0 million in 2007 were 22.5 percent higher than earnings of $122.4 million in 2006. The increase in earnings was due to an additional three months of GSW earnings, higher earnings in China, and sales of higher margin products all of which offset lower residential water heater volume.

Electrical Products

Sales in our Electrical Products segment in 2008 were $858.1 million or 4.0 percent lower than 2007. Increased selling prices to offset higher costs for raw materials were more than offset by lower unit volume caused by the weak housing market as well as customer inventory reductions at the end of the year. Sales in 2007 of $894.0 million were 1.3 percent lower than 2006. Similar to 2008, the favorable impact of materials related pricing actions was more than offset by the negative impact of a weak housing market. Additionally, lower volume in the residential hermetic and pump motor markets more than offset improved sales in the commercial hermetic and distribution market segments.

Operating earnings at our Electrical Products segment were $39.1 million in 2008 compared with $23.1 million in 2007. The majority of the increase in earnings was due to a decrease in restructuring charges from $22.8 million in 2007 to $8.7 million in 2008. Operating earnings in 2007 were $25.0 million lower than earnings of $48.1 million in 2006 due to an increase in restructuring charges of $13.9 million and lower unit volumes. Please refer to the previous discussion on restructuring charges for additional details.

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 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 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.

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 arms-length basis. The estimated fair value is then compared with the carrying amount of the reporting unit, including recorded goodwill. We are subject to financial statement risk to the extent that goodwill and indefinite-lived intangible assets become impaired. Any impairment review is, by its nature, highly judgmental as estimates of future sales, earnings and cash flows are utilized to determine fair values. However, we believe that we conduct annual thorough and competent valuations of goodwill and indefinite-lived intangible assets and that there has been no impairment.

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 on a periodic basis. At times, warranty issues may arise which are beyond the scope of our historical experience. While our warranty costs have historically been within its calculated estimates, it is possible that future warranty costs could differ significantly from those estimates. We provide for any such warranty issues as they become known and estimable. The allocation of the warranty liability between current and long-term is based on the expected warranty liability to be paid in the next year as determined by historical product failure rates.

Product liability

Due to the nature of our products, we are subject to product liability claims in the normal course of business. A majority of these claims involve our Water Products business. We maintain insurance to reduce our risk. Most insurance coverage includes self-insured retentions that vary by year. As of December 31, 2008, we maintained a self-insured retention of $5.0 million per occurrence with an aggregate insurance limit of $125.0 million per occurrence.

GSW insurance coverage included self-insurance retentions that varied by business segment and by year. Effective April 3, 2006 GSW maintained a $25.0 million aggregate loss retention through self-insurance and captive insurance company coverage. GSW claims occurring on or after July 1, 2006 are covered under the company’s insurance program.

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 use 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.

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 assets, retirement ages, and years of service. Consideration is given to current market conditions, including changes in interest rates in making these assumptions. Our assumptions for the expected rate of return on plan assets is 8.75 percent in 2008, unchanged from 2007. The discount rate used to determine net periodic pension costs increased from 5.90 percent in 2007 to 6.50 percent in 2008. In 2009, the rate of return on plan assets is 8.75 percent and the discount rate is 6.60 percent.

In developing our expected long-term rate of return assumption, we evaluate our pension plan’s target asset allocation, the historical 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 between 60 to 70 percent, with the remainder allocated primarily to bond managers and a small allocation to private equity managers. Due to market fluctuations, our actual asset allocation as of December 31, 2008, was 55 percent to equity managers, 36 percent to bond managers, six percent to private equity managers and the remainder in money market instruments. We regularly review our actual asset allocation and periodically rebalance our investments to our targeted allocation when considered appropriate. Our pension plan’s historical 10-year and 25-year compounded annualized returns are 4.0 percent and 10.2 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 8.75 percent expected return on assets for 2009 is reasonable.

The discount rate assumptions used to determine future pension obligations at December 31, 2008, 2007 and 2006 were based on the Hewitt top quartile yield Curve (HTQ), which was designed by Hewitt Associates to provide a means for plan sponsors to value the liabilities of their postretirement benefit plans. The HTQ is a hypothetical double A yield curve represented by a series of annualized individual discount rates. Each bond issue underlying the HTQ is required to have a rating of Aa or better by Moody’s Investor Service, Inc. or a rating of AA or better by Standard & Poor’s. Because of the volatile bond market, we adjusted our discount rate as of December 31, 2008 to take into account the effect of bonds that were on credit watch on December 31, 2008 and were subsequently downgraded below a AA rating before January 15, 2009. The discount rates

determined on the basis described above were 6.60 percent. 6.50 percent and 5.90 percent at December 31, 2008, 2007 and 2006, respectively. We will continue to evaluate our actuarial assumptions at least annually, and we will adjust the assumptions as necessary.

We estimate that we will recognize approximately $10.0 million of pension expense in 2009 compared to $4.0 million in 2008. Lowering the expected long-term rate of return on assets by 25 basis points would increase our net pension expense for 2009 by approximately $1.7 million. Lowering the discount rate by 25 basis points would increase our 2009 net pension expense by approximately $1.3 million.

Recent Accounting Pronouncements

In March 2008, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 161, “Disclosures about Derivative Instruments and Hedging Activities, an Amendment of FASB No. 133,” (“SFAS 161”). SFAS 161 is intended to improve transparency in financial reporting by requiring enhanced disclosures of an entity’s derivative instruments and hedging activities and their effects on the entity’s financial position, financial performance, and cash flows. SFAS 161 applies to all derivative instruments within the scope of SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” (“SFAS 133”). SFAS 161 also applies to non-derivative hedging instruments and all hedged items designated and qualifying under SFAS 133. SFAS 161 is effective prospectively for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. SFAS 161 encourages, but does not require, comparative disclosures for periods prior to its initial adoption. We will adopt SFAS 161 on January 1, 2009 and are currently evaluating the potential impact on our financial statements when implemented.

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements, an amendment of ARB No. 51”, (“SFAS 160”). SFAS 160 changes the accounting and reporting for minority interests, which will be recharacterized as noncontrolling interests and classified as a component of equity. This new consolidation method changes the accounting for transactions with minority interest holders. SFAS 160 is effective beginning in 2009. Adoption of this statement will impact our accounting for any future transactions which include a noncontrolling interest.

In December 2007, the FASB issued SFAS No. 141(R), “Business Combinations,” (“SFAS 141(R)”). SFAS 141(R) requires us to continue to follow the guidance in SFAS 141 for certain aspects of business combinations, with additional guidance provided defining the acquirer, recognizing and measuring the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree, assets and liabilities arising from contingencies, defining a bargain purchase and recognizing and measuring goodwill or a gain from a bargain purchase. In addition, certain transaction costs previously capitalized as part of the purchase price will be expensed as incurred. Also, under SFAS 141(R) adjustments associated with changes in tax contingencies that occur after the one year measurement period are recorded as adjustments to income. This statement is effective for all business combinations for which the acquisition date is on or after the beginning of an entity’s first fiscal year that begins after December 15, 2008; however, the guidance in this standard regarding the treatment of income tax contingencies is retrospective to business combinations completed prior to January 1, 2009. We will adopt SFAS 141(R) for any business combinations occurring at or subsequent to January 1, 2009.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities including an amendment of FASB Statement No. 115 (“SFAS 159”), which permits entities to choose to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities without having to apply complex hedge accounting provisions. We adopted SFAS 159 on January 1, 2008. Adoption of this statement did not have an affect on our consolidated financial condition, results of operations or cash flows.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” (“SFAS 157”). SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. SFAS 157 also establishes a fair value hierarchy that prioritizes information used in developing assumptions when pricing an asset or liability. As discussed in footnote 1 we adopted SFAS 157 on January 1, 2008. Adoption of this statement did not have a material impact on our consolidated financial condition, results of operations or cash flows.

Outlook

Given the deteriorating global economic environment that intensified during the fourth quarter we are forecasting significantly lower volumes for both our residential and commercial businesses in both operating companies. In addition we expect an increase of more than $6 million in pension expense.

Also, there are a number of factors that we believe will contribute to earnings this year, including improvement in water heater pricing, continued growth—although at a slower rate—in China, and savings from the restructuring initiative at Electrical Products Company. At the same time, we continue to reduce cost throughout our operations. We announced in January, 2009 a company-wide workforce reduction program for our salaried workforce.

Notwithstanding these factors which could improve earnings, the weak economy will challenge us throughout the year and consequently, we expect 2009 earnings will be in a range between $2.40 and $2.60 per share.

OTHER MATTERS

Environmental

Our operations are governed by a number of federal, state, local and foreign 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 2008 and are not expected to be material in any single year. We have accrued amounts 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.

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 for certain raw materials (i.e. copper and aluminum) 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, 2008, we had commodity futures contracts amounting to $53.9 million of commodity purchases. A hypothetical ten percent change in the underlying commodity price of such contracts would have a potential impact of $5.4 million. It is important to note that gains and losses from our 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, 2008, we had net foreign currency contracts outstanding of $196.4 million. Assuming a hypothetical ten percent movement in the respective currencies, the potential foreign exchange gain or loss associated with the change in rates would amount to $19.6 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, 2008, we had $159.6 million in outstanding floating-rate debt with a weighted-average interest rate of 1.8 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 pretax interest expense of approximately $0.3 million.

Smith Investment Company Transaction

On December 9, 2008, we entered into a merger agreement with our largest stockholder, Smith Investment Company, pursuant to which Smith Investment would become our wholly-owned subsidiary. Assuming the merger is completed, the stockholders of Smith Investment will own our shares directly, rather than through Smith Investment. Smith Investment owns approximately 97.9 percent of our outstanding Class A Common Stock and approximately 7.1 percent of our outstanding Common Stock.

We and our stockholders are expected to benefit from the merger because its terms provide for:

•

An exchange ratio in the merger agreement reflecting a discount of 1.5 percent such that the merger will result in a reduction in the number of our outstanding shares by issuing to Smith Investment stockholders 98.5 percent of the total number of our shares that Smith Investment holds before the merger;

•

An increase in the public float for our shares, as our shares currently held by Smith Investment will be distributed more broadly among the Smith Investment stockholders; and

•

Enhancement of our corporate governance structure through proposed amendments to our certificate of incorporation that provide for the following:

•

An increase in the percentage of members of our board of directors that holders of our Common Stock, voting as a separate class, elect from 25 percent to 33.3 percent of the members of the board of directors;

•

Shares of our Class A Common Stock to convert automatically into shares of our Common Stock, subject to certain exceptions, upon transfer to unaffiliated third parties, and

•

All shares of our Class A Common Stock to convert automatically into shares of our Common Stock once the outstanding shares of our Class A Common Stock fall below 2,397,976 shares, which is approximately 8 percent of the total outstanding shares of our Class A Common Stock and our Common Stock as of the date of the merger agreement.

The proposed amendments to our certificate of incorporation also provide for an increase, solely for purposes of completing the merger, in the total number of authorized shares of our Class A Common Stock that we can issue from 14,000,000 shares to 22,667,252 shares.

Certain members of the Smith Family have agreed to vote their shares to approve the merger agreement at a meeting of Smith Investment stockholders. Similarly, Smith Investment has agreed to vote its shares to approve the merger agreement and the amendments to our certificate of incorporation at a meeting of our stockholders. These stockholders have enough votes to ensure approval of the transaction at the respective stockholders meetings of our company and Smith Investment.

In addition to receipt of approval of stockholders of our company and Smith Investment, the merger is subject to receipt of a favorable letter ruling from the Internal Revenue Service, the effectiveness of a registration statement covering our shares to be issued to the Smith Investment stockholders and other customary closing conditions. Under the terms of the agreement, Smith Investment will reimburse us for substantially all of its transaction-related expenses. In addition, a portion of our Common Stock to be issued to the Smith Investment stockholders having a market value of $15 million as of the effective time of the merger will be placed in escrow to satisfy indemnification claims, if any, by us in connection with the transaction. We expect the merger to close by the end of the second quarter of 2009.

The pending transaction between A. O. Smith and SICO will be accounted for as a reverse acquisition with SICO as the accounting acquirer and A. O. Smith as the accounting acquiree (which is the surviving entity for legal purposes). As this is a common control transaction under SFAS 141(R) Business Combinations, the transaction will be accounted for as an equity transaction under SFAS 160 Noncontrolling interests in Consolidated Financial Statements an amendment of ARB No. 51. The acquisition of a noncontrolling interest will not require purchase accounting.

Furthermore, because SICO is treated as the continuing reporting entity for accounting purposes, the reports filed by A. O. Smith, as the surviving corporation in the transaction, after the date of the transaction will parallel the financial reporting required under United States generally accepted accounting principles and SEC reporting rules as if SICO were the legal successor to its reporting obligation as of the date of the transaction. Accordingly, prior period financial information presented in the A. O. Smith financial statements will reflect the historical activity of SICO.

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 residential and commercial gas and electric water heating equipment, as well as fractional horsepower alternating current, direct current, and hermetic electric motors. The company’s products are manufactured and marketed primarily in North America and China. Water heaters are sold through both wholesale and retail channels to plumbing wholesalers and retail outlets. Electric motors are sold principally to original equipment manufacturers and distributors.

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, floating rate debt and trade payables approximated fair value as of December 31, 2008 and 2007, due to the short maturities or frequent rate resets of these instruments. The fair value of term notes with insurance companies was approximately $140.7 million as of December 31, 2008 compared with the carrying amount of $150.1 million for the same period. The carrying amount of term notes with insurance companies approximated fair value as of December 31, 2007. The fair value is estimated based on current rates offered for debt with similar maturities.

Foreign currency translation. For all subsidiaries outside the United States, with the exception of all Mexican operations and two of 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 Mexican operations and two of the Chinese 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 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 82 percent of the company’s total inventory at December 31, 2008 and 2007. 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, 3 to 20 years for equipment and 3 to 7 years for software. Maintenance and repair costs are expensed as incurred.

Goodwill and other intangibles. Goodwill and indefinite-lived intangible assets are not amortized but are reviewed for impairment on an annual basis. Intangible assets of $78.8 million including $32.1 million with an indefinite life were recorded as part of the GSW Inc (GSW) acquisition (see Note 2). Indefinite-lived assets totaled $34.6 million and $38.0 million at December 31, 2008 and 2007, respectively. The decrease in 2008 was due to currency translation adjustment. 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 10 to 25 years. Amortization of $4.3 million, $4.5 million and $2.9 million was recorded in 2008, 2007 and 2006, respectively. In the future, amortization should approximate $4.1 million annually and the intangible assets will be amortized over a weighted average period of 16 years. Total accumulated amortization at December 31, 2008 and 2007 was $12.5 million and $9.3 million, respectively.

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

1. Organization and Significant Accounting Policies (continued)

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. Statement of Financial Accounting Standards (SFAS) No. 133, 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. Any fair value changes are recorded in net earnings or other comprehensive earnings.

The company utilizes certain derivative instruments to enhance its ability to manage currency and interest rate exposures as well as 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 Futures Contracts

In addition to entering into supply arrangements in the normal course of business, the company also enters into futures contracts to fix the cost of certain raw material purchases, principally copper and aluminum, 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 $52.1 million and $3.5 million are recorded in current liabilities as of December 31, 2008 and 2007 respectively. The value of the effective portion of the contracts of $(31.0) million and $(2.0) million as of December 31, 2008 and 2007, respectively, was recorded in accumulated other comprehensive loss, net of tax, and will be 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 in 2008, 2007 and 2006.

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, Chinese renminbi, Canadian dollar and Euro.

Forward contracts are designated and accounted for as cash flow hedges of a forecasted transaction. Derivative currency liabilities of $19.1 million and assets of $2.9 million as of December 31, 2008 and 2007, respectively, were recorded in other current liabilities and assets. 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 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.

The majority of the amounts in accumulated other comprehensive loss for cash flow hedges is expected to be reclassified into earnings within one year.

1. Organization and Significant Accounting Policies (continued)

The following table summarizes, by currency, the contractual amounts of the company’s foreign currency forward contracts.


December 31 (dollars in millions)	2008				2007
	Buy		Sell		Buy		Sell
Euro	$	6.1	$	1.9	$	5.5	$	2.2
Canadian dollar		-		17.1		-		24.1
Hungarian forint		-		-		1.5		-
Chinese renminbi		64.8		-		32.5		-
Mexican peso		110.3		-		85.5		-

Total	$	181.2	$	19.0	$	125.0	$	26.3

The forward contracts in place at December 31, 2008 and 2007, amounted to approximately 69 percent and 60 percent, respectively, of the company’s anticipated subsequent year exposure for those currencies hedged.

Interest Rate Swap Agreement

The company is exposed to interest rate risk as a result of its floating rate borrowings under its revolving credit facility. The company uses interest rate swaps to manage this risk. As of December 31, 2008, the company had one interest rate swap outstanding in the amount of $25 million that expires in November 2010.

The interest rate swap is designated and accounted for as a cash flow hedge of floating rate debt. A derivative interest rate liability of $1.8 million and $0.7 million as of December 31, 2008 and 2007, respectively were recorded in accrued liabilities. Gains and losses on this instrument 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 statement of earnings. The assessment of effectiveness for the interest rate swap is based on changes in floating rate interest rates. This swap has been determined to be perfectly effective.

Fair Value Measurements. The company adopted SFAS No. 157, “Fair Value Measurements” (“SFAS 157”) on January 1, 2008. SFAS 157, 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. SFAS 157 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, SFAS 157 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 is prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

Liabilities measured at fair value on a recurring basis are as follows (dollars in millions):


		Fair Value Measurement Using
Description	Total December 31, 2008	Quoted Prices In Active Markets for Identical Contracts (Level 1)	Significant Other Observable Inputs (Level 2)
Net derivative contracts	$ (73.0)	$ (52.1)	$ (20.9)

1. Organization and Significant Accounting Policies (continued)

There were no changes in our valuation techniques used to measure fair values on a recurring basis as a result of adopting SFAS 157.

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 collectibility based on the creditworthiness of the customer as determined by credit checks and analysis, as well as the customer’s payment history, and does not require collateral on sales. The allowance for doubtful accounts was $6.3 million and $7.2 million at December 31, 2008 and 2007, respectively.

Accruals 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. Advertising costs are charged to operations as incurred and amounted to $40.3, $38.0 and $30.5 million during 2008, 2007 and 2006, respectively.

Research and development. Research and development costs are charged to operations as incurred and amounted to $48.5, $47.8 and $42.3 million during 2008, 2007 and 2006, respectively.

Product warranties. The company’s products carry warranties that generally range from one to ten years and are based on terms that are generally accepted in the market. The company records a liability for the expected cost of warranty-related claims at the time of sale. The allocation of our 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 2008 and 2007:


Years ended December 31 (dollars in millions)	2008			2007
Balance at beginning of year	$	105.5		$	98.7
GSW acquisition		—			5.0
Expense		73.0			54.8
Claims settled		(66.7	)		(53.0	)

Balance at end of year	$	111.8		$	105.5

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.

Stock-based compensation. Effective January 1, 2006, the company adopted Statement of Financial Accounting Standards (“SFAS”) No. 123(R), “Share-Based Payment” (“SFAS 123(R)”), using the modified-prospective transition method. Under that method compensation cost is recognized beginning with the effective date (a) based on the requirements of SFAS 123(R) for all share-based payments granted after the effective date and (b) based on the requirements of SFAS 123 for all awards granted to employees prior to the effective date of SFAS 123(R) that remain unvested on the effective date. SFAS 123(R) had no impact on the company’s financial position, statement of operations or cash flows at the date of adoption. SFAS 123(R) requires measurement of the cost of employee services received in exchange for an award of equity instruments based on the fair value of the award at the date of grant. Compensation cost is recognized using the straight-line method over the vesting period of the award. SFAS 123(R) also requires the benefits of tax deductions in excess of recognized compensation

1. Organization and Significant Accounting Policies (continued)

cost to be reported as a financing cash flow, rather than as an operating cash flow as required under prior literature. Excess tax deductions of $1.1 million, $4.8 million and $4.2 million were recognized as a financing cash flow in 2008, 2007 and 2006, respectively. This requirement reduced net operating cash flows and increased net financing cash flows in periods after adoption. The company cannot estimate what those amounts will be in the future because they depend on, among other things, when employees exercise stock options.

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:


	2008	2007	2006
Denominator for basic earnings per share - weighted-average shares outstanding	30,061,373	30,560,727	30,406,088
Effect of dilutive stock options, restricted stock and share units	228,598	412,353	597,785

Denominator for diluted earnings per share	30,289,971	30,973,080	31,003,873

Restricted marketable securities. As described in Note 2, the company acquired GSW in 2006. GSW operated a captive insurance company to provide product liability and general liability insurance to its subsidiary American Water Heater Co. (American). The company decided to cover American’s prospective liability exposures with its existing insurance programs and all product liability claims for events which occurred prior to July 1, 2006 will be financed by the captive. The reinsurance company restricts the amount of capital which must be maintained by the captive and this restricted amount is $26.3 million and $38.9 million at December 31, 2008 and 2007, respectively. The $26.3 million and $38.9 million of restricted money market instruments are included in other assets on the company’s balance sheet at December 31, 2008 and 2007, respectively. The cost of the money market instruments approximates fair value.

Recent accounting pronouncements. In March 2008, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities, an Amendment of FASB No. 133,” (“SFAS 161”). SFAS 161 is intended to improve transparency in financial reporting by requiring enhanced disclosures of an entity’s derivative instruments and hedging activities and their effects on the entity’s financial position, financial performance, and cash flows. SFAS 161 applies to all derivative instruments within the scope of SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” (“SFAS 133”). SFAS 161 also applies to non-derivative hedging instruments and all hedged items designated and qualifying under SFAS 133. SFAS 161 is effective prospectively for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. SFAS 161 encourages, but does not require, comparative disclosures for periods prior to its initial adoption. We will adopt SFAS 161 on January 1, 2009 and are currently evaluating the potential impact on our financial statements when implemented.

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements, an amendment of ARB No. 51.”, (“SFAS 160”). SFAS 160 changes the accounting and reporting for minority interests, which will be recharacterized as noncontrolling interests and classified as a component of equity. This new consolidation method changes the accounting for transactions with minority interest holders. SFAS 160 is effective beginning in 2009. Adoption of this statement will impact our accounting for any future transactions which include a noncontrolling interest.

1. Organization and Significant Accounting Policies (continued)

contingencies is retrospective to business combinations completed prior to January 1, 2009. We will adopt SFAS 141(R) for any business combinations occurring at or subsequent to January 1, 2009.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities—including an amendment of FASB Statement No. 115 (“SFAS 159”), which permits entities to choose to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities without having to apply complex hedge accounting provisions. We adopted SFAS 159 on January 1, 2008. Adoption of this statement did not have an affect on our consolidated financial condition, results of operations or cash flows.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” (“SFAS 157”). SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. SFAS 157 also establishes a fair value hierarchy that prioritizes information used in developing assumptions when pricing an asset or liability. As discussed earlier in this footnote we adopted SFAS 157 on January 1, 2008. Adoption of this statement did not have a material impact on our consolidated financial condition, results of operations or cash flows.

2. Acquisitions

On April 3, 2006, the company acquired GSW, a publicly traded Canadian-based manufacturer which operated in two business segments: water heaters and building products. The water heating segment manufactures and markets water heaters sold in the U.S. and Canada through its American and GSW Water Heater subsidiaries. The addition of GSW to the company’s existing water heater operations expanded the company’s share of the growing retail channel of the U.S. residential water heater market segment as well as increased its presence in the Canadian residential water heater market segment. On December 19, 2006, the company sold the building products business for $11.4 million and in 2007, recorded a reduction in sales proceeds of $0.4 million associated with a working capital adjustment. For accounting purposes, the operations of the building products business are reported as a discontinued operation.

The aggregate purchase price, net of $39.3 million of cash acquired, was $307.7 million. This was comprised of $339.3 million for the outstanding stock and $7.7 million of acquisition costs principally incurred in 2005. In addition, $36.9 million of payments were made for change in control provisions and tax liabilities assumed.

The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition as finalized in 2007. The non-deductible goodwill has been recorded within the Water Products segment. Of the $78.8 million of acquired intangible assets, $32.1 million was assigned to indefinite-lived trademarks that are not subject to amortization and $46.7 million was assigned primarily to customer relationships which have amortization periods ranging from 10 to 25 years.


April 3, 2006 (dollars in millions)
Current assets, net of cash acquired	$	157.2
Current assets held for sale		16.6
Property, plant and equipment		60.8
Intangible assets		78.8
Goodwill		193.8
Other assets		36.8

Total assets acquired		544.0
Current liabilities		143.5
Current liabilities held for sale		4.4
Long-term liabilities		88.4

Total liabilities assumed		236.3

Net assets acquired	$	307.7

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 the April 3, 2006 date of acquisition.

The pro forma unaudited results of operations for the year ended December 31, 2006 assuming consummation of the purchase as of January 1, 2006, would result in diluted earnings per share of $2.59 compared to stated diluted earnings per share of $2.47.

3. Restructuring and Other Charges

Electrical Products Restructuring and Related Charges

In 2006, $7.3 million of expense was recognized for the continuation of domestic repositioning activities. The majority of the charge is related to the closure of the McMinnville, TN, motor fabrication plant which was completed in the first quarter of 2007. Additionally, a pretax charge of $1.6 million was recognized for the closure of the Taizhou, China plant which was closed in the fourth quarter of 2006.

In 2007, $13.6 million of expense was recognized for the continuation of domestic repositioning activities. Included in this full year amount is an asset impairment charge of $10.6 million. The majority of the domestic repositioning charges relate to the closure of the Scottsville, KY and Mebane, NC production facilities resulting in the consolidation of the hermetic motor assembly operations in Acuna, Mexico and Suzhou, China. The closures were completed in the fourth quarter of 2008.

Additionally, in 2007, Electrical Products recognized $9.2 million of expense (of which $7.5 million is an asset impairment charge), and a $9.9 million tax benefit related to the closure of its Budapest, Hungary facility. The closure of its Budapest Hungary facility resulted in the remaining operations being transferred to China. The plant closed in the second quarter of 2008.

In 2008, $8.7 million of expense was recognized for severance and asset impairment and moving costs associated with the completion of Electrical Products restructuring programs. Included in this amount was a nontaxable $2.9 million favorable translation adjustment recognized upon closure of the Budapest, Hungary facility.

The following table presents an analysis of the company’s Electrical Products restructuring reserve as of and for the years ended December 31, 2008 , 2007 and 2006 (dollars in millions):

Other Charges – Tower Automotive, Inc.

The company was the primary lessee on a facility lease in Corydon, Indiana related to a business sold to Tower Automotive, Inc. (Tower) in 1997. The company entered into a sublease arrangement with Tower in 1997 with the same terms and conditions as the company lease. Tower filed for bankruptcy on February 2, 2005 and subsequently notified the company that it would reject the sublease arrangement effective October 1, 2005. In order to minimize costs, the company purchased the Corydon facility for $4.5 million on October 11, 2005. The company recognized $0.5 million, $0.5 million and $0.4 million expense in 2008, 2007 and 2006, respectively, related to facility maintenance and the company’s estimate of its ultimate net loss upon disposition of this facility.

3. Restructuring and Other Charges (continued)

Other Charges – Previously Owned Businesses

In 2007, the company recognized $1.4 million of expense associated with retained liabilities of previously owned businesses which were sold by the company between 1997 – 2001. The majority of the $1.4 million expense is related to certain costs associated with previously owned real estate. The company recognized expense of $0.3 million in 2006 related to the settlement of an environmental liability.

Long-term debt	$	317.3	$	379.6

The company has a $425 million multi-year multi-currency revolving credit agreement with a group of eight banks, which expires on February 17, 2011. The facility has an accordion provision which allows it to be increased up to $500 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, 2008 and 2007. At its option, the company maintains either cash balances or pays fees for bank credit and services.

Scheduled maturities of long-term debt within each of the five years subsequent to December 31, 2008, are as follows: 2009-$17.5; 2010—$21.1; 2011-$196.7; 2012-$25.1; 2013-$18.6 million.

8. Debt and Lease Commitments (continued)

Future minimum payments under non-cancelable operating leases relating mostly to office, manufacturing and warehouse facilities total $48.5 million and are due as follows: 2009–$14.0; 2010 $10.3; 2011 $6.8; 2012 $4.0; 2013-$2.7, and thereafter – $10.7 million. Rent expense, including payments under operating leases, was $25.0, $26.6 and $25.6 million in 2008, 2007 and 2006, respectively.

Interest paid by the company was $19.2, $26.7 and $24.9 million in 2008, 2007 and 2006, respectively.

9. 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. Class A Common Stock is convertible to Common Stock on a one for one basis.

During 2008, 2007 and 2006, 11,079, 23,540 and 193,975 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 $.74, $.70 and $.66 per share in 2008, 2007 and 2006, respectively.

In February 2007, the company’s Board of Directors authorized the purchase of up to 1,000,000 shares of its outstanding Common Stock. As of December 31, 2007, the company has completed this program at a total cost of $36.6 million. In December 2007, the company’s Board of Directors authorized the purchase of an additional 1,000,000 shares of its outstanding Common Stock. No shares were purchased in 2008.

At December 31, 2008, 32,595 and 2,339,033 shares of Class A Common Stock and Common Stock, respectively, were held as treasury stock. At December 31, 2007, 32,595 and 2,463,745 shares of Class A Common Stock and Common Stock, respectively, were held as treasury stock.

10. Stock Based Compensation

The company adopted the A. O. Smith Combined Incentive Compensation Plan (the “plan”) effective January 1, 2007. The plan is a continuation of the A. O. Smith Combined Executive Incentive Compensation Plan which was originally approved by shareholders in 2002. The plan provides for the issuance of 1,250,000 stock options, restricted stock or share units. Stock options are issued 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 options, restricted stock or share units under the predecessor plan, if that plan was in effect, will be available for granting of share based awards under the plan. The number of shares available for granting of options or share units at December 31, 2008, was 893,124. Upon stock option exercise, restricted stock grant, or share unit vesting, shares are issued from Treasury stock.

Total stock based compensation cost recognized in 2008, 2007 and 2006 was $5.0, $4.6 and $2.8 million, respectively.

10. Stock Based Compensation (continued)

Stock options

The stock options granted in 2008, 2007 and 2006 have a three year pro rata vesting from the date of grant. For active employees, all options granted in 2008, 2007 and 2006 expire ten years after date of grant. Stock option compensation recognized in 2008, 2007 and 2006 was $1.9, $1.7 and $0.7 million, respectively. Included in the stock option expense recognized in 2008 and 2007 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:

Exercisable at end of year	25.74	963,034	845,601		1,274,567

The aggregate intrinsic value for the outstanding and exercisable options as of December 31, 2008 is $4.5 million and $4.5 million, respectively. The average remaining contractual life for outstanding and exercisable options is 6 years and 5 years, respectively.

10. Stock Based Compensation (continued)

The following table summarizes weighted-average information by range of exercise prices for stock options outstanding and exercisable at December 31, 2008:


Range of Exercise Prices	Options Outstanding at December 31, 2008	Weighted- Average Exercise Price		Options Exercisable at December 31, 2008	Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Life
$13.56	76,300	$	13.56	76,300	$	13.56	2 years
$15.14	128,300		15.14	128,300		15.14	3 years
$23.98 to $40.27	1,084,467		31.01	758,434		28.76	7 years

	1,289,067			963,034

The weighted-average fair value per option at the date of grant during 2008, 2007 and 2006, using the Black-Scholes option-pricing model, was $11.59, $14.43 and $12.94, respectively. Assumptions were as follows:


	2008	2007	2006
Expected life (years)	6.4	6.5	6.4
Risk-free interest rate	3.7%	4.7%	4.4%
Dividend yield	2.0%	1.8%	2.2%
Expected volatility	35.1%	36.0%	38.0%

The expected life is based on historical exercise behavior and the projected exercise of unexercised stock options. The risk free interest rate is based on the U.S. Treasury yield curve in effect on the date of grant for the respective expected life of the option. The expected dividend yield is based on the expected annual dividends divided by the grant date market value of our common stock. The expected volatility is based on the historical volatility of our common stock.

Restricted stock and share units

Participants may also be awarded shares of restricted stock or share units under the plan. The company granted 144,008, 68,600, and 21,000 share units under the plan in 2008, 2007 and 2006, respectively. Included in the 2008 grant are share units granted on April 30, 2008 which are subject to performance conditions and which will vest on December 31, 2010. The ultimate number of share units that will vest will range from zero to 96,000 based on the average of the company’s annual return on equity for the eleven quarters ending December 31, 2010. Compensation expense will be recognized ratably over the vesting period as long as achievement of the performance conditions is considered probable.

The restricted stock and share units were valued at $4.9, $2.7 and $0.8 million at the date of issuance in 2008, 2007 and 2006, respectively, and will be recognized as compensation expense ratably over the three-year vesting period. Compensation expense of $3.1, $2.9 and $2.3 million was recognized in 2008, 2007 and 2006, respectively. Included in share based compensation expense recognized in 2008 and 2007 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.

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


	Number of Units		Weighted-Average Grant Date Value
Outstanding at January 1, 2008	212,500		$32.91

Granted	144,008		33.69

Vested	(123,900	)	28.54

Terminated	(626	)	35.64


Outstanding at December 31, 2008	231,982		$35.40

10. Stock Based Compensation (continued)

Total compensation expense for restricted stock and share units not yet recognized is $3.5 million at December 31, 2008. The weighted average period over which the expense is expected to be recognized is one year.

11. Pension and Other Post-retirement Benefits

The company provides retirement benefits for all United States employees including benefits for employees of previously owned businesses which were earned up to the date of sale. The company also has several foreign pension plans, none of which are material to the company’s financial position.

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.

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.

On December 31, 2006, the company adopted SFAS No. 158, “Employer’s Accounting for Defined Benefit Pension and Other Postretirement Plans - an amendment of FASB Statements No. 87, 88, 106 and 132(R).” SFAS 158 requires that the company recognize the overfunded or underfunded status of its defined benefit and retiree medical plans as an asset or liability in the balance sheet with changes in the funded status recognized through comprehensive income in the year in which they occur. The impact of adoption was a one time before tax charge to accumulated other comprehensive loss of $28.3 million.

Total Recognized in Net Periodic Cost and Other Comprehensive Earnings	$	241.8		$	(42.6	)		N/A		$	0.6		$	0.5			N/A

The estimated net actuarial loss and prior service cost for the pension plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2009 are $11.9 million and $0.3 million, respectively. The estimated net actuarial loss and prior year service cost for the post-retirement benefit plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2009 are each less than $0.1 million. As permitted under paragraph 26 of FASB Statement No. 87 and paragraph 53 of Statement No. 106, the amortization of any prior service cost is determined using a straight-line amortization of the cost over the average remaining service period of employees expected to receive benefits under the Plan.

The 2008 and 2007 after tax adjustments for additional minimum pension liability resulted in other comprehensive gain (loss) of $(145.0) million and $33.8 million, respectively.

Assumptions

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


	Pension Benefits		Post-retirement Benefits
	2008	2007	2008	2007
Discount rate	6.6%	6.5%	6.6%	6.5%
Average salary increases	4.0%	4.0%	4.0%	4.0%

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


	Pension Benefits			Post-retirement Benefits
Years ended December 31	2008	2007	2006	2008	2007	2006
Discount rate	6.50%	5.90%	5.75%	6.50%	5.90%	5.75%
Expected long-term return on plan assets	8.75%	8.75%	8.75%	n/a	n/a	n/a
Rate of compensation increase	4.00%	4.00%	4.00%	4.00%	4.00%	4.00%

11. Pension and Other Post-retirement Benefits (continued)

In developing the expected long-term rate of return assumption, the company evaluated its pension plan’s target and actual asset allocation and historical long-term rates of return of equity and bond indices. The company also considered its pension plan’s historical 10-year and 25-year compounded annualized returns of 4.0 percent and 10.3 percent, respectively.

Assumed health care cost trend rates

Assumed health care cost trend rates as of December 31 are as follows:


	2008	2007
Health care cost trend rate assumed for next year	10.00%	10.00%
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate)	5.00%	5.00%
Year that the rate reaches the ultimate trend rate	2014	2013

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	2008		2007
Equity securities	55	%	71	%
Debt securities	36		24
Private equity	6		4
Other	3		1

	100	%	100	%

The company’s target allocation to equity managers is between 60 to 70 percent with the remainder allocated primarily to bond managers and a small allocation to private equity managers. The company regularly reviews its actual asset allocation and periodically rebalances its investments to the targeted allocation when considered appropriate.

There is no company stock included in plan assets at December 31, 2008 and 2007.

Cash Flows

In 2008, the company made contributions of $17.3 million and will be required to make a contribution of $18 million in 2009. The company is anticipating making a contribution in 2009 in the range of $18 to $35 million.

International		(0.8	)		2.2			2.5

	$	27.9		$	11.7		$	28.6

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


Years ended December 31	2008		2007		2006
Provision at U.S. federal statutory rate	35.0	%	35.0	%	35.0	%
U.S. tax benefit for closure of Budapest, Hungary facility	-		(9.9	)	-
State income and franchise taxes, net of federal benefit	1.8		1.4		2.4

Research tax credits	(0.7	)	(0.7	)	-
U.S. manufacturing deduction	(0.2	)	(0.5	)	(0.3	)
Other	0.7		(1.9	)	0.3

	25.4	%	11.7	%	27.3	%

Components of earnings from continuing operations before income taxes were as follows:


Years ended December 31 (dollars in millions)	2008		2007		2006
United States	$	35.4	$	43.0	$	59.3
International		74.4		56.9		45.5

	$	109.8	$	99.9	$	104.8

Total taxes paid by the company amounted to $15.7, $14.1, and $37.3 million in 2008, 2007 and 2006, respectively. Included in the 2007 and 2006 taxes paid are $4.2 million and $9.2 million of net tax payments for the companies acquired in 2006 relating to periods before the acquisition.

12. Income Taxes (continued)

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, 2008, the undistributed earnings amounted to $248.1 million. Determination of the amount of unrecognized deferred tax liability on the undistributed earnings is not practicable. In addition, no provision or benefits 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:

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 millions)	2008		2007
Current deferred income tax assets	$	63.2	$	34.0
Long-term deferred income tax assets (liabilities)		49.8		(34.5	)


Net (liability) asset	$	113.0	$	(0.5	)

The company has foreign net operating loss carryovers with tax benefits of $3.9 million. Of the $3.9 million of tax benefits, $3.3 million have an unlimited carryover period and $0.6 million expire in 2016. Based on future realizability, a valuation allowance of $3.9 million has been established against the foreign net operating loss carryover tax benefits.

The company has a $4.0 million charitable contribution carryover that expires in 2013. The company also has state and local net operating loss carryovers having a tax value of $5.9 million and state and local tax credit carryovers of $1.0 million. These carryovers expire between 2010 and 2028. Based on future realizability, no valuation allowance has been established against the charitable contribution or state and local carryover tax benefits.

There was no change in the valuation allowance for 2008. During 2007 the valuation allowance was decreased and goodwill decreased by $1.3 million to reflect expected utilization of tax benefits previously acquired with the State Industries, Inc. acquisition in 2001. Also, in 2007 the valuation allowance was increased by $0.7 million for the current year tax benefits of foreign loss carryovers that are not expected to be utilized and decreased by $0.2 million to reflect expiration of foreign net operating losses.

In China, foreign investment enterprises engaged in manufacturing activities are granted favorable tax treatment during start-up periods. The enterprises are granted a two-year tax exemption and a three-year 50% tax rate reduction beginning with the enterprise’s first profit making year. In 2008 two of the company's China subsidiaries benefited from the favorable tax treatment. The consolidated earnings would have been $0.05 per share lower without the tax holiday.

12. Income Taxes (continued)

The Company adopted the provisions of FIN 48 on January 1, 2007. There was no cumulative effect of adoption recorded to retained earnings. A reconciliation of the beginning and ending amount of unrecognized benefits is as follows:


(Dollars in millions)	2008			2007
Balance at January 1	$	4.8		$	7.6
Additions based on tax positions related to the current year		0.8			0.5
Additions for tax positions of prior years		-			-
Reductions for tax positions of prior years		(0.1	)		(3.3	)

Balance at December 31	$	5.5		$	4.8

The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $4.2 million. The company recognizes potential interest and penalties related to unrecognized tax benefits as a component of tax expense. At January 1, 2007 there was $0.8 million of interest and penalties accrued. The amount was reduced to $0.4 million at December 1, 2007 and was increased to $0.5 million during 2008. It is not anticipated there will be a significant change in the total amount of unrecognized tax benefits in the next 12 months. The company’s U.S. federal tax returns for 2005-2008 are subject to audit. The company is subject to state and local audits for tax years 2003-2008. The company is subject to non-U.S. income tax examinations for years 2001-2008.

13. Commitments and Contingencies

The company is a potentially responsible party in eight judicial and administrative proceedings initiated on behalf of various state and federal regulatory agencies seeking to clean up sites which have been environmentally impacted and to recover costs they have incurred or will incur as to the sites.

The company has established reserves for the sites and insurance proceeds and potential recovery from third parties are available to cover a portion of the company’s potential liability. The company believes that any environmental claims for these sites in excess of reserves, insurance proceeds and indemnified amounts will not have a material effect on its financial position or results of operations.

The company or its subsidiaries have been named as a co-defendant in lawsuits alleging personal injury as a result of exposure to asbestos integrated into certain of the company’s or its subsidiaries’ products or premises. The company and its subsidiaries have never manufactured asbestos. As of December 31, 2008 the company and its subsidiaries are defendants in active lawsuits involving claims by approximately 6,990 plaintiffs. The company and its subsidiaries have made no payment in a substantial majority of the cases closed to date. The remainder of the resolved cases have settled for amounts that are not material to the company, and the vast majority of the costs of defense and settlements have been paid in part by insurance, and the company believes it has adequate insurance coverage to cover its exposure.

The company has been named as a co-defendant in lawsuits alleging manganese-induced illness involving claims by approximately 1,698 plaintiffs. The claimants in these lawsuits allege that exposure to manganese in welding consumables caused them to develop adverse neurological conditions, including a condition known as manganism, and are seeking compensatory and, in many instances, punitive damages, usually for unspecified sums. The company manufactured welding consumables from 1918 until it sold that business to another company in 1965. The company has not been found liable in any of the lawsuits and has not paid any settlements. The costs of defense have been paid by insurance, and the company believes it has adequate insurance coverage to cover its exposure.

13. Commitments and Contingencies (continued)

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 which it believes are adequate to cover incurred claims. For the years ended December 31, 2008 and 2007, the company had $125 million of product liability insurance for individual losses in excess of $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.

In Form 8-K filed with the Securities and Exchange Commission on October 19, 2007, the company disclosed an adverse verdict in a product liability lawsuit in Baldwin County, Alabama. On February 19, 2008, all plaintiffs executed a Release, Settlement and Confidentiality Agreement (the Settlement) resolving the lawsuit in its entirety. The Settlement was approved by the Baldwin County Court and the adverse verdict will be vacated. The terms of the Settlement are confidential. The company's expense related to the Settlement was included in the reserve recorded as of December 31, 2007.

14. Operations by Segment

The company has two reportable segments: Water Products and Electrical Products. The Water Products segment manufactures residential and commercial gas and electric water heaters used in a wide range of applications including hotels, laundries, car washes, factories and large institutions. In addition, the Water Products segment manufactures copper tube boilers used in large-volume hot water and hydronic heating applications. The Electrical Products segment manufactures fractional horsepower alternating current (AC) and direct current (DC) motors used in fans and blowers in furnaces, air conditioners and ventilating systems; as well as in other consumer products such as home appliances and pumps for 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 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, is used to measure the performance of the segments and allocate resources.

ITEM 9A – CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, have evaluated the effectiveness of the Company’s 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, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures are effective in recording, processing, summarizing, and reporting, on a timely basis, information required to be disclosed by the Company in the reports that it files or submits 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

The Company’s 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). The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s internal control over financial reporting based on the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, the company’s management has concluded that, as of December 31, 2008, the Company’s 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 and Young LLP, an independent registered public accounting firm, has audited the Company’s consolidated financial statements and the effectiveness of internal controls over financial reporting as of December 31, 2008 as stated in their report which is included herein.

Changes in Internal Control Over Financial Reporting

There has not been any change in the Company’s internal control over financial reporting during the quarter ended December 31, 2008, that has materially affected, or is reasonable likely to materially affect, the Company’s internal control over financial reporting.

ITEM 9B - OTHER INFORMATION

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, 2008, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (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’s 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.

In our opinion, A.O. Smith Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2008, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of A.O. Smith Corporation as of December 31, 2008 and 2007, and the related consolidated statements of earnings, comprehensive earnings, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2008 and our report dated January 30, 2009 expressed an unqualified opinion thereon.

EXHIBIT A

Section 8.2 shall be replaced by the following:

Deemed Investments. The Deferred Compensation Account of a Participant shall be credited with an investment return determined as if the account were invested in one or more investment funds made available by the Committee. The Participant shall elect the investment funds in which his Deferred Compensation Account shall be deemed to be invested. Such election shall be made in the manner prescribed by the Committee and shall take effect upon the entry of the Participant into the Plan. The investment election of the Participant shall remain in effect until a new election is made by the Participant. In the event the Participant fails for any reason to make an effective election of the investment return to be credited to his account, the investment return shall be determined by the Committee. Notwithstanding the foregoing, a Participant shall not be permitted to select a deemed investment fund with regard to deferrals of restricted stock units, which deferrals shall be deemed invested in the Company common stock fund.

Section 8.3.3 shall be replaced by the following:

The Deferred Compensation Account shall be credited or debited on each day securities are traded on a national stock exchange with the amount of deemed investment gain or loss resulting from the performance of the investment funds elected by the Participant in accordance with Section 8.2. The amount of such deemed investment gain or loss shall be determined by the Committee and such determination shall be final and conclusive upon all concerned.

If any dividends or other distributions are paid on shares of the Company’s common stock while a Participant has a deemed investment in the Company common stock fund, such Participant shall be credited with an additional amount (in the form of additional common stock units) equal to the amount of the cash dividend paid or the fair market value of other property distributed on one share of Company common stock, multiplied by the number of common stock units credited to the Participant’s Deferred Compensation Account on the date the dividend is declared. The additional amount shall be converted into additional common stock units using the fair market value of a share of Company common stock on the date the dividend is paid or distributed. Any other provision of this Plan to the contrary notwithstanding, if a dividend is paid on shares of Company common stock in the form of a right or rights to purchase shares of capital stock of the Company or any entity acquiring the Company, no additional common stock units shall be credited to the Participant’s Deferred Compensation Account with respect to such dividend, but each common stock Unit credited to a Participant’s Deferred Compensation Account at the time such dividend is paid, and each common stock unit thereafter credited to the Participant’s Deferred Compensation Account at a time when such rights are attached to shares of the Company’s common stock, shall thereafter be valued as of any point in time on the basis of the aggregate of the then fair market value of one share of common stock plus the then fair market value of such right or rights then attached to one share. For purposes hereof, the term “fair market value” shall be determined consistent with the Company’s equity incentive plan as in effect from time to time.

In the event of any merger, share exchange, reorganization, consolidation, recapitalization, stock dividend, stock split or other change in corporate structure of the Company affecting its shares of common stock, the Committee may make appropriate equitable adjustments with respect to the common stock units credited to the Deferred Compensation Account of each Participant as the Committee determines is necessary or desirable to prevent the dilution or enlargement of the benefits intended to be provided under the Plan.

Participants shall have no rights as a stockholder pertaining to common stock units credited to their Deferred Compensation Accounts. No Participant or Beneficiary shall have any right to receive a distribution of Company stock under this Plan. All distributions from the Participant’s Deferred Compensation Account are made in cash.

Section 11 shall be replaced by the following:

Allocation of Responsibilities:

The persons responsible for the Plan and the duties and responsibilities allocated to each are as follows:


11.1		Board.

(i)		To appoint and remove members of the Committee.

11.2		Committee.

Section 4. Credits to Deferred Compensation Account:

4.1 Participant Deferral Credits. To the extent provided in the Adoption Agreement, each Active Participant may elect, by entering into a Participation Agreement with the Employer, to defer the receipt of Compensation from the Employer by a dollar

amount or percentage specified in the Participation Agreement. The amount of Compensation the Participant elects to defer, the Participant Deferral Credit, shall be credited by the Employer to the Deferred Compensation Account maintained for the Participant pursuant to Section 8. The following special provisions shall apply with respect to the Participant Deferral Credits of a Participant:

4.1.1 The Employer shall credit to the Participant’s Deferred Compensation Account on each Crediting Date an amount equal to the total Participant Deferral Credit for the period ending on such Crediting Date.

4.1.2 An election pursuant to this Section 4.1 shall be made by the Participant by executing and delivering a Participation Agreement to the Committee. Except as otherwise provided in this Section 4.1, the Participation Agreement shall become effective with respect to such Participant as of the first day of January following the date such Participation Agreement is received by the Committee. A Participant’s election may be changed at any time prior to the last permissible date for making the election as permitted in this Section 4.1, and shall thereafter be irrevocable. The election of a Participant shall continue in effect for subsequent years until modified by the Participant as permitted in this Section 4.1.

4.1.3 A Participant may execute and deliver a Participation Agreement to the Committee within 30 days after the date the Participant first becomes eligible to participate in the Plan to be effective as of the first payroll period next following the date the Participation Agreement is fully executed. Whether a Participant is treated as newly eligible for participation under this Section shall be determined in accordance with Section 409A of the Code and the regulations thereunder, including (i) rules that treat all elective deferral account balance plans as one plan, and (ii) rules that treat a previously eligible employee as newly eligible if his benefits had been previously distributed or if he has been ineligible for 24 months. For Compensation that is earned based upon a specified performance period (for example, an annual bonus), where a deferral election is made under this Section but after the beginning of the performance period, the election will only apply to the portion of the Compensation equal to the total amount of the Compensation for the service period multiplied by the ratio of the number of days remaining in the performance period after the election over the total number of days in the performance period.

4.1.4 A Participant may unilaterally modify a Participation Agreement (either to terminate, increase or decrease the portion of his future Compensation which is subject to deferral within the percentage limits set forth in Section 4.1 of the Adoption Agreement) by providing a written modification of the Participation Agreement to the Committee. The modification shall become effective as of the first day of January following the date such written modification is received by the Committee.

4.1.5 If the Participant performed services continuously from the later of the beginning of the performance period or the date upon which the performance criteria are established through the date upon which the Participant makes an initial deferral election, a Participation Agreement relating to the deferral of Performance-Based Compensation may be executed and delivered to the Committee no later than the date which is 6 months prior to the end of the performance period, provided that in no event may an election to defer Performance-Based Compensation be made after such Compensation has become readily ascertainable.

4.1.6 If the Employer has a fiscal year other than the calendar year, Compensation relating to Service in the fiscal year of the Employer (such as a bonus based on the fiscal year of the Employer), of which no amount is paid or payable during the fiscal year, may be deferred at the Participant’s election if the election to defer is made not later than the close of the Employer’s fiscal year next preceding the first fiscal year in which the Participant performs any services for which such Compensation is payable.

4.1.7 Compensation payable after the last day of the Participant’s taxable year solely for services provided during the final payroll period containing the last day of the Participant’s taxable year (i.e., December 31) is treated for purposes of this Section 4.1 as Compensation for services performed in the subsequent taxable year.

4.1.8 The Committee may from time to time establish policies or rules consistent with the requirements of Section 409A of the Code to govern the manner in which Participant Deferral Credits may be made

4.1.9 If a Participant becomes Disabled or applies for and is eligible for a distribution on account of an Unforeseeable Emergency during a Plan Year, his deferral election for such Plan Year shall be cancelled.

4.2 Employer Credits. If designated by the Employer in the Adoption Agreement, the Employer shall cause the Committee to credit to the Deferred Compensation Account of each Active Participant an Employer Credit as determined in accordance with the Adoption Agreement. A Participant must make distribution elections with respect to any Employer Credits credited to his Deferred Compensation Account by the deadline that would apply under Section 4.1 for distribution elections with respect to Participant Deferral Credits credited at the same time, on a Participation Agreement that is timely executed and delivered to the Committee pursuant to Section 4.1.

4.3 Deferred Compensation Account. All Participant Deferral Credits and Employer Credits shall be credited to the Deferred Compensation Account of the Participant as provided in Section 8.

Section 5. Qualifying Distribution Events:

5.1 Separation from Service. If the Participant Separates from Service with the Employer, the vested balance in the Deferred Compensation Account shall be paid to the Participant by the Employer as provided in Section 7. Notwithstanding the foregoing, no distribution shall be made earlier than six months after the date of Separation from Service (or, if earlier, the date of death) with respect to a Participant who as of the date of Separation from Service is a Specified Employee of a corporation the stock in which is traded on an established securities market or otherwise. Any payments to which such Specified Employee would be entitled during the first six months following the date of Separation from Service shall be accumulated and paid on the first day of the seventh month following the date of Separation from Service.

5.2 Disability. If the Employer designates in the Adoption Agreement that distributions are permitted under the Plan when a Participant becomes Disabled, and the Participant becomes Disabled while in Service, the vested balance in the Deferred Compensation Account shall be paid to the Participant by the Employer as provided in Section 7.

5.3 Death. If the Participant dies while in Service, the Employer shall pay a benefit to the Participant’s Beneficiary in the amount designated in the Adoption Agreement. Payment of such benefit shall be made by the Employer as provided in Section 7.

5.4 In-Service or Education Distributions. If the Employer designates in the Adoption Agreement that in-service or education distributions are permitted under the Plan, a Participant may designate in the Participation Agreement to have a specified amount credited to the Participant’s In-Service or Education Account for in-service or education distributions at the date specified by the Participant. In no event may an in-service or education distribution of an amount be made before the date that is two years after the first day of the year in which such amount was credited to the In-Service or Education Account. Notwithstanding the foregoing, if a Participant incurs a Qualifying Distribution Event prior to the date on which the entire balance in the In-Service or Education Account has been distributed, then the balance in the In-Service or Education Account on the date of the Qualifying Distribution Event shall be paid as provided under Section 7.1 for payments on such Qualifying Distribution Event.

5.5 Change in Control Event. If the Employer designates in the Adoption Agreement that distributions are permitted under the Plan upon the occurrence of a Change in Control Event, the Participant may designate in the Participation Agreement to have the vested balance in the Deferred Compensation Account paid to the Participant upon a Change in Control Event by the Employer as provided in Section 7.

5.6 Unforeseeable Emergency. If the Employer designates in the Adoption Agreement that distributions are permitted under the Plan upon the occurrence of an Unforeseeable Emergency event, a distribution from the Deferred Compensation Account may be made to a Participant in the event of an Unforeseeable Emergency, subject to the following provisions:

5.6.1 A Participant may, at any time prior to his Separation from Service for any reason, make application to the Committee to receive a distribution in a lump sum of all or a portion of the vested balance in the Deferred Compensation Account (determined as of the date the distribution, if any, is made under this Section 5.6) because of an Unforeseeable Emergency. A distribution because of an Unforeseeable Emergency shall not exceed the amount required to satisfy the Unforeseeable Emergency plus amounts necessary to pay taxes reasonably anticipated as a result of such distribution, after taking into account the extent to which the Unforeseeable Emergency may be relieved through reimbursement or compensation by insurance or otherwise or by liquidation of the Participant’s assets (to the extent the liquidation of such assets would not itself cause severe financial hardship) or by stopping current deferrals under the Plan pursuant to Section 4. 1.9.

5.6.2 The Participants request for a distribution on account of Unforeseeable Emergency must be made in writing to the Committee. The request must specify the nature of the financial hardship, the total amount requested to be distributed from the Deferred Compensation Account, and the total amount of the actual expense incurred or to be incurred on account of the Unforeseeable Emergency.

5.6.3 If a distribution under this Section 5.6 is approved by the Committee, such distribution will be made as soon as practicable following the date it is approved. The processing of the request shall be completed as soon as practicable from the date on which the Committee receives the properly completed written request for a distribution on account of an Unforeseeable Emergency. If a Participant’s Separation from Service occurs after a request is approved in accordance with this Section 5.6.3, but prior to distribution of the full amount approved, the approval of the request shall be automatically null and void and the benefits which the Participant is entitled to receive under the Plan shall be distributed in accordance with the applicable distribution provisions of the Plan.

5.6.4 The Committee may from time to time adopt additional policies or rules consistent with the requirements of Section 409A of the Code to govern the manner in which such distributions may be made so that the Plan may be conveniently administered.

Section 6. Vesting:

A Participant shall be fully vested in the portion of his Deferred Compensation Account attributable to Participant Deferral Credits, and all income, gains and losses attributable thereto. A Participant shall become fully vested in the portion of his Deferred Compensation Account attributable to Employer Credits, and income, gains and losses attributable thereto, in accordance with the vesting schedule and provisions designated by the Employer in the Adoption Agreement. If a Participant’s Deferred Compensation Account is not fully vested upon Separation from Service, the portion of the Deferred Compensation Account that is not fully vested shall thereupon be forfeited.

Section 7. Distribution Rules:

7.1 Payment Options. The Employer shall designate in the Adoption Agreement the payment options which may be elected by the Participant (lump sum, annual installments, or a combination of both). Different payment options may be made available for each Qualifying Distribution Event, and different payment options may be available for different types of Separations from Service, all as designated in the Adoption Agreement. The Participant shall elect in the Participation Agreement the method under which the vested balance in the Deferred Compensation Account will be distributed from among the designated payment options. The Participant may at such time elect a different method of payment for each Qualifying Distribution Event as specified in the Adoption Agreement. If the Participant is permitted by the Employer in the Adoption Agreement to elect different payment options and does not make a valid election, the vested balance in the Deferred Compensation Account will be distributed as a lump sum.

Notwithstanding the foregoing, if certain Qualifying Distribution Events occur prior to the date on which the vested balance of a Participant’s Deferred Compensation Account is completely paid pursuant to this Section 7.1 following the occurrence of certain initial Qualifying Distribution Events, the following rules apply:

7.1.1 If the initial Qualifying Distribution Event is a Separation from Service or Disability, and the Participant subsequently dies, the remaining unpaid vested balance of a Participant’s Deferred Compensation Account shall be paid as a lump sum.

7.1.2 If the initial Qualifying Distribution Event is a Change in Control Event, and any subsequent Qualifying Distribution Event occurs (except an In-Service or Education Distribution described in Section 2.29(iv)), the remaining unpaid vested balance of a Participant’s Deferred Compensation Account shall be paid as provided under Section 7.1 for payments on such subsequent Qualifying Distribution Event.

7.2 Timing of Payments. Payment shall be made in the manner elected by the Participant and shall commence as soon as practicable after (but no later than 60 days after) the distribution date elected for the Qualifying Distribution Event. In the event the Participant fails to make a valid election of the payment method, the distribution will be made in a single lump sum payment as soon as practicable after (but no later than 60 days after) the Qualifying Distribution Event. A payment may be further delayed to the extent permitted in accordance with regulations and guidance under Section 409A of the Code.

7.3 Installment Payments. If the Participant elects to receive installment payments upon a Qualifying Distribution Event, the payment of each annual installment shall be made on the anniversary of the date of the first installment payment, and the amount of the annual installment shall be adjusted on such anniversary for credits or debits to the Participant’s account pursuant to Section 8 of the Plan. Such adjustment shall be made by dividing the balance in the Deferred Compensation Account on such date by the number of annual installments remaining to be paid hereunder; provided that the last annual installment due under the Plan shall be the entire amount credited to the Participant’s account on the date of payment.

7.4 De Minimis Amounts. Notwithstanding any payment election made by the Participant, if the Employer designates a pre-determined de minimis amount in the Adoption Agreement, the vested balance in the Deferred Compensation Account of the Participant will be distributed in a single lump sum payment if at the time of a permitted Qualifying Distribution Event the vested balance does not exceed such pre-determined de minimis amount; provided, however, that such distribution will be made only where the Qualifying Distribution Event is a Separation from Service, death, Disability (if applicable) or Change in Control Event (if applicable). Such payment shall be made on or before the later of (i) December 31 of the calendar year in which the Qualifying Distribution Event occurs, or (ii) the date that is 2-¹/2 months after the Qualifying Distribution Event occurs. In addition, the Employer may distribute a Participant’s vested balance at any time if the balance does not exceed the limit in Section 402(g)(l)(B) of the Code and results in the termination of the Participant’s entire interest in the Plan as provided under Section 409A of the Code.

7.5 Subsequent Elections. With the consent of the Committee, a Participant may delay or change the method of payment of the Deferred Compensation Account subject to the following requirements:

7.5.1 The new election may not take effect until at least 12 months after the date on which the new election is made.

7.5.2 If the new election relates to a payment for a Qualifying Distribution Event other than the death of the Participant, the Participant becoming Disabled, or an Unforeseeable Emergency, the new election must provide for the deferral of the payment for a period of at least five years from the date such payment would otherwise have been made.

7.5.3 If the new election relates to a payment from the In-Service or Education Account, the new election must be made at least 12 months prior to the date of the first scheduled payment from such account.

For purposes of this Section 7.5 and Section 7.6, a payment is each separately identified amount to which the Participant is entitled under the Plan; provided, that entitlement to a series of installment payments is treated as the entitlement to a single payment.

7.6 Acceleration Prohibited. The acceleration of the time or schedule of any payment due under the Plan is prohibited except as expressly provided in regulations and administrative guidance promulgated under Section 409A of the Code (such as accelerations for domestic relations orders and employment taxes). It is not an acceleration of the time or schedule of payment if the Employer waives or accelerates the vesting requirements applicable to a benefit under the Plan.

Section 8. Accounts; Deemed Investment; Adjustments to Account:

8.1 Accounts. The Committee shall establish a book reserve account, entitled the “Deferred Compensation Account,” on behalf of each Participant. The Committee shall also establish an In-Service or Education Account as a part of the Deferred Compensation Account of each Participant, if applicable. The amount credited to the Deferred Compensation Account shall be adjusted pursuant to the provisions of Section 8.3.

8.2 Deemed Investments. The Deferred Compensation Account of a Participant shall be credited with an investment return determined as if the account were invested in one or more investment funds made available by the Committee. The Participant shall elect the investment funds in which his Deferred Compensation Account shall be deemed to be invested. Such election shall be made in the manner prescribed by the Committee and shall take effect upon the entry of the Participant into the Plan. The investment

election of the Participant shall remain in effect until a new election is made by the Participant. In the event the Participant fails for any reason to make an effective election of the investment return to be credited to his account, the investment return shall be determined by the Committee.

8.3 Adjustments to Deferred Compensation Account. With respect to each Participant who has a Deferred Compensation Account under the Plan, the amount credited to such account shall be adjusted by the following debits and credits, at the times and in the order stated:

8.3.1 The Deferred Compensation Account shall be debited each business day with the total amount of any payments made from such account since the last preceding business day to him or for his benefit.

8.3.2 The Deferred Compensation Account shall be credited on each Crediting Date with the total amount of any Participant Deferral Credits and Employer Credits to such account since the last preceding Crediting Date.

8.3.3 The Deferred Compensation Account shall be credited or debited on each day securities are traded on a national stock exchange with the amount of deemed investment gain or loss resulting from the performance of the investment funds elected by the Participant in accordance with Section 8.2. The amount of such deemed investment gain or loss shall be determined by the Committee and such determination shall be final and conclusive upon all concerned.

Section 9. Administration by Committee:

9.1 Membership of Committee. If the Committee consists of individuals appointed by the Board, they will serve at the pleasure of the Board. Any member of the Committee may resign, and his successor, if any, shall be appointed by the Board.

9.2 General Administration. The Committee shall be responsible for the operation and administration of the Plan and for carrying out its provisions. The Committee shall have the full authority and discretion to make, amend, interpret, and enforce all

appropriate rules and regulations for the administration of this Plan and decide or resolve any and all questions, including interpretations of this Plan, as may arise in connection with this Plan. Any such action taken by the Committee shall be final and conclusive on any party. To the extent the Committee has been granted discretionary authority under the Plan, the Committee’s prior exercise of such authority shall not obligate it to exercise its authority in a like fashion thereafter. The Committee shall be entitled to rely conclusively upon all tables, valuations, certificates, opinions and reports furnished by any actuary, accountant, controller, counsel or other person employed or engaged by the Employer with respect to the Plan. The Committee may, from time to time, employ agents and delegate to such agents, including employees of the Employer, such administrative or other duties as it sees fit.

9.3 Indemnification. To the extent not covered by insurance, the Employer shall indemnify the Committee, each employee, officer, director, and agent of the Employer, and all persons formerly serving in such capacities, against any and all liabilities or expenses, including all legal fees relating thereto, arising in connection with the exercise of their duties and responsibilities with respect to the Plan, provided however that the Employer shall not indemnify any person for liabilities or expenses due to that person’s own gross negligence or willful misconduct

Section 10. Contractual Liability:

10.1 Contractual Liability. Unless otherwise elected in the Adoption Agreement, the Company shall be obligated to make all payments hereunder. This obligation shall constitute a contractual liability of the Company to the Participants, and such payments shall be made from the general funds of the Company. The Company shall not be required to establish or maintain any special or

separate fund, or otherwise to segregate assets to assure that such payments shall be made, and the Participants shall not have any interest in any particular assets of the Company by reason of its obligations hereunder. To the extent that any person acquires a right to receive payment from the Company, such right shall be no greater than the right of an unsecured creditor of the Company.

10.2 Trust. The Employer may establish a trust to assist it in meeting its obligations under the Plan. Any such trust shall conform to the requirements of a grantor trust under Revenue Procedures 92-64 and 92-65 and at all times during the continuance of the trust the principal and income of the trust shall be subject to claims of general creditors of the Employer under federal and state law. The establishment of such a trust would not be intended to cause Participants to realize current income on amounts contributed thereto, and the trust would be so interpreted and administered.

Section 11. Allocation of Responsibilities:

The persons responsible for the Plan and the duties and responsibilities allocated to each are as follows:

11.1

Board.

(i)

To amend the Plan;

(ii)

To appoint and remove members of the Committee; and

Section 12. Benefits Not Assignable; Facility of Payments:

12.1 Benefits Not Assignable. No portion of any benefit credited or paid under the Plan with respect to any Participant shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge, and any attempt so to anticipate, alienate, sell, transfer, assign, pledge, encumber or charge the same shall be void, nor shall any portion of such benefit be in any manner payable to any assignee, receiver or any one trustee, or be liable for his debts, contracts, liabilities, engagements or torts. Notwithstanding the foregoing, in the event that all or any portion of the benefit of a Participant is transferred to the former Spouse of the Participant incident to a divorce, the Committee shall maintain such amount for the benefit of the former Spouse until distributed in the manner required by an order of any court having jurisdiction over the divorce, and the former Spouse shall be entitled to the same rights as the Participant with respect to such benefit.

12.2 Plan-Approved Domestic Relations Orders. The Committee shall establish procedures for determining whether an order directed to the Plan is a Plan-Approved Domestic Relations Order. If the Committee determines that an order is a Plan-Approved

Domestic Relations Order, the Committee shall cause the payment of amounts pursuant to or segregate a separate account as provided by (and to prevent any payment or act which might be inconsistent with) the Plan-Approved Domestic Relations Order.

12.3 Payments to Minors and Others. If any individual entitled to receive a payment under the Plan shall be physically, mentally or legally incapable of receiving or acknowledging receipt of such payment, the Committee, upon the receipt of satisfactory evidence of his incapacity and satisfactory evidence that another person or institution is maintaining him and that no guardian or committee has been appointed for him, may cause any payment otherwise payable to him to be made to such person or institution so maintaining him. Payment to such person or institution shall be in full satisfaction of all claims by or through the Participant to the extent of the amount thereof.

Section 13. Beneficiary:

The Participant’s beneficiary shall be the person, persons, entity or entities designated by the Participant on the beneficiary designation form provided by and filed with the Committee or its designee. If the Participant does not designate a beneficiary, the beneficiary shall be his Surviving Spouse. If the Participant does not designate a beneficiary and has no Surviving Spouse, the beneficiary shall be the Participant’s estate. The designation of a beneficiary may be changed or revoked only by filing a new beneficiary designation form with the Committee or its designee. If a beneficiary (the “primary beneficiary”) is receiving or is entitled to receive payments under the Plan and dies before receiving all of the payments due him, the balance to which he is entitled shall be paid to the contingent beneficiary, if any, named in the Participant’s current beneficiary designation form. If there is no contingent

beneficiary, the balance shall be paid to the estate of the primary beneficiary. Any beneficiary may disclaim all or any part of any benefit to which such beneficiary shall be entitled hereunder by filing a written disclaimer with the Committee before payment of such benefit is to be made. Such a disclaimer shall be made in a form satisfactory to the Committee and shall be irrevocable when filed. Any benefit disclaimed shall be payable from the Plan in the same manner as if the beneficiary who filed the disclaimer had predeceased the Participant.

Section 14. Amendment and Termination of Plan:

The Company may amend any provision of the Plan or terminate the Plan at any time; provided, that in no event shall such amendment or termination reduce the balance in any Participant’s Deferred Compensation Account as of the date of such amendment or termination, nor shall any such amendment affect the terms of the Plan relating to the payment of such Deferred Compensation Account. Notwithstanding the foregoing, the following special provisions shall apply:

14.1 Termination in the Discretion of the Employer. Except as otherwise provided in Sections 14.2, the Company in its discretion may terminate the Plan and distribute benefits to Participants subject to the following requirements and any others specified under Section 409A of the Code:

14.1.1 All arrangements sponsored by the Employer that would be aggregated with the Plan under Section l.409A-l(c) of the Treasury Regulations are terminated.

14.1.2 No payments other than payments that would be payable under the terms of the Plan if the termination had not occurred are made within 12 months of the termination date.

14.1.3 All benefits under the Plan are paid within 24 months of the termination date.

14.1.4 The Employer does not adopt a new arrangement that would be aggregated with the Plan under Section 1.409A-l(c) of the Treasury Regulations providing for the deferral of compensation at any time within 3 years following the date of termination of the Plan.

14.1.5 The termination does not occur proximate to a downturn in the financial health of the Employer.

14.2 Termination Upon Change in Control Event.

Section 15. Communication to Participants:

The Employer shall make a copy of the Plan available for inspection by Participants and their beneficiaries during reasonable hours at the principal office of the Employer.

Section 16. Claims Procedure:

The following claims procedure shall apply with respect to the Plan:

16.1 Filing of a Claim for Benefits. If a Participant or Beneficiary (the “claimant”) believes that he is entitled to benefits under the Plan which are not being paid to him or which are not being accrued for his benefit, he shall file a written claim therefore with the Committee.

16.2 Notification to Claimant of Decision. Within 90 days after receipt of a claim by the Committee (or within 180 days if special circumstances require an extension of time), the Committee shall notify the claimant of the decision with regard to the claim. In the event of such special circumstances requiring an extension of time, there shall be furnished to the claimant prior to expiration

of the initial 90-day period written notice of the extension, which notice shall set forth the special circumstances and the date by which the decision shall be furnished. If such claim shall be wholly or partially denied, notice thereof shall be in writing and worded in a manner calculated to be understood by the claimant, and shall set forth: (i) the specific reason or reasons for the denial; (ii) specific reference to pertinent provisions of the Plan on which the denial is based; (iii) a description of any additional material or information necessary for the claimant to perfect the claim and an explanation of why such material or information is necessary; and (iv) an explanation of the procedure for review of the denial and the time limits applicable to such procedures, including a statement of the claimant’s right to bring a civil action under ERISA following an adverse benefit determination on review. Notwithstanding the foregoing, if the claim relates to a disability determination, the Committee shall notify the claimant of the decision within 45 days (which may be extended for an additional 30 days if required by special circumstances).

16.3 Procedure for Review. Within 60 days following receipt by the claimant of notice denying his claim, in whole or in part, or, if such notice shall not be given, within 60 days following the latest date on which such notice could have been timely given, the claimant may appeal denial of the claim by filing a written application for review with the Committee. Following such request for review, the Committee shall fully and fairly review the decision denying the claim. Prior to the decision of the Committee, the claimant shall be given an opportunity to review pertinent documents and to submit issues and comments in writing.

16.4 Decision on Review. The decision on review of a claim denied in whole or in part by the Committee shall be made in the following manner:

16.4.1 Within 60 days following receipt by the Committee of the request for review (or within 120 days if special circumstances require an extension of time), the Committee shall notify the claimant in writing of its decision with regard to the claim. In the event of such special circumstances requiring an extension of time, written notice of the extension shall be furnished to the claimant prior to the commencement of the extension. Notwithstanding the foregoing, if the claim relates to a disability determination, the Committee shall notify the claimant of the decision within 45 days (which may be extended for an additional 45 days if required by special circumstances).

16.4.2 With respect to a claim that is denied in whole or in part, the decision on review shall set forth specific reasons for the decision, shall be written in a manner calculated to be understood by the claimant, and shall set forth:

(i)

the specific reason or reasons for the adverse determination;

(ii)

specific reference to pertinent Plan provisions on which the adverse determination is based;

(iii)

a statement that the claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the claimant’s claim for benefits; and

(iv)

a statement describing any voluntary appeal procedures offered by the Plan and the claimant’s right to obtain the information about such procedures, as well as a statement of the claimant’s right to bring an action under ERISA section 502(a).

16.4.3 The decision of the Committee shall be final and conclusive.

16.5 Action by Authorized Representative of Claimant. All actions set forth in this Section 16 to be taken by the claimant may likewise be taken by a representative of the claimant duly authorized by him to act in his behalf on such matters. The Committee may require such evidence as either may reasonably deem necessary or advisable of the authority to act of any such representative.

Section 17. Miscellaneous Provisions:

17.1 Set off. Notwithstanding any other provision of this Plan, the Employer may reduce the amount of any payment otherwise payable to or on behalf of a Participant hereunder (net of any required withholdings) at the time payment is due by the amount of any loan, cash advance, extension of credit or other obligation of the Participant to the Employer that is then due and payable, and the Participant shall be deemed to have consented to such reduction. In addition, the Employer may at any time offset a Participant’s Deferral Compensation Account by an amount up to $5,000 to collect any such amount in accordance with the requirements of Section 409A of the Code.

17.2 Notices. Each Participant who is not in Service and each Beneficiary shall be responsible for furnishing the Committee or its designee with his current address for the mailing of notices and benefit payments. Any notice required or permitted to be given to such Participant or Beneficiary shall be deemed given if directed to such address and mailed by regular United States mail, first class, postage prepaid. If any check mailed to such address is returned as undeliverable to the addressee, mailing of checks will be suspended until the Participant or Beneficiary furnishes the proper address. This provision shall not be construed as requiring the mailing of any notice or notification otherwise permitted to be given by posting or by other publication.

17.3 Lost Distributees. A benefit shall be deemed forfeited if the Committee is unable to locate the Participant or Beneficiary to whom payment is due on or before the fifth anniversary of the date payment is to be made or commence; provided, that the deemed investment rate of return pursuant to Section 8.2 shall cease to be applied to the Participant’s account following the first anniversary of such date; provided further, however, that such benefit shall be reinstated if a valid claim is made by or on behalf of the Participant or Beneficiary for all or part of the forfeited benefit.

17.4 Reliance on Data. The Employer and the Committee shall have the right to rely on any data provided by the Participant or by any Beneficiary. Representations of such data shall be binding upon any party seeking to claim a benefit through a Participant, and the Employer and the Committee shall have no obligation to inquire into the accuracy of any representation made at any time by a Participant or Beneficiary.

17.5 Receipt and Release for Payments. Subject to the provisions of Section 17.1, any payment made from the Plan to or with respect to any Participant or Beneficiary, or pursuant to a disclaimer by a Beneficiary, shall, to the extent thereof, be in full satisfaction of all claims hereunder against the Plan and the Employer with respect to the Plan. The recipient of any payment from the Plan may be required by the Committee, as a condition precedent to such payment, to execute a receipt and release with respect thereto in such form as shall be acceptable to the Committee.

17.6 Headings. The headings and subheadings of the Plan have been inserted for convenience of reference and are to be ignored in any construction of the provisions hereof.

17.7 Continuation of Employment. The establishment of the Plan shall not be construed as conferring any legal or other rights upon any Employee or any persons for continuation of employment, nor shall it interfere with the right of the Employer to discharge any Employee or to deal with him without regard to the effect thereof under the Plan.

17.8 Merger or Consolidation: Assumption of Plan. No Employer shall consolidate or merge into or with another corporation or entity, or transfer all or substantially all of its assets to another corporation, partnership, trust or other entity (a “Successor Entity”) unless such Successor Entity shall assume the rights, obligations and liabilities of the Employer under the Plan and upon such assumption, the Successor Entity shall become obligated to perform the terms and conditions of the Plan. Nothing herein shall prohibit the assumption of the obligations and liabilities of the Employer under the Plan by any Successor Entity.

17.9 Construction. The Employer shall designate in the Adoption Agreement the state according to whose laws the provisions of the Plan shall be construed and enforced, except to the extent that such laws are superseded by ERISA and the applicable requirements of the Code.

17.10 Taxes. The Employer or other payor may withhold a benefit payment under the Plan or a Participant’s wages, or the Employer may reduce a Participant’s Account balance, in order to meet any federal, state, or local or employment tax withholding obligations with respect to Plan benefits, as permitted under Section 409A of the Code. The Employer or other payor shall report Plan payments and other Plan-related information to the appropriate governmental agencies as required under applicable laws.

(a) Entitlement. An Executive shall he entitled to receive a lump sum payment (the “Single Sum Pension Plan Supplement”) from the Company under this Plan if he terminates employment with the Company and its Affiliates on or after completion of five (5) Years of Service.

(b) Normal Retirement or Special Early Retirement Benefit. If an Executive described in subsection (a) terminates employment from the Company and its Affiliates on or after his Normal Retirement Age, or on or after his Special Early Retirement Age and completion of ten (10) Years of Service, then the amount of the Executive’s Single Sum Pension Plan Supplement shall be determined as follows:

(1)

First, calculate a monthly amount payable in a single life annuity form (assuming benefits commence immediately on the date of the Executive’s termination of employment) equal to:

(A)

1.65% of the Executive’s Average Monthly Earnings multiplied by the number of years of Credited Service (as defined in the Pension Plan), but not more than forty (40) years;

(B)

minus the total monthly retirement benefit actually payable to the Executive from the Pension Plan as of the Executive’s date of termination of employment (the result, the “Monthly Benefit Amount”);

(C)

minus the federal, state and local income and employment taxes that would be owed by the Executive on the Monthly Benefit Amount, calculated assuming the Executive pays taxes at the highest marginal tax rates for federal, state and local income tax purposes, based on the location of the Executive’s primary residence at the time of his termination of employment (the result, the “After-Tax Monthly Benefit Amount”);

(2)

Second, multiply the After-Tax Monthly Benefit Amount by the Annuity Factor for an immediately commencing annuity (the result, the “Single Sum Amount”);

(3)

Third, determine an additional amount such that the net amount retained by the Executive, after payment of any federal, state or local income tax or employment tax with respect to the Single Sum Amount, and any federal, state and local income tax or employment tax upon the payment provided for by this clause, is equal to the Single Sum Amount (the “Gross-Up Amount”). For purposes of determining the Gross-Up Amount, the Company shall use the

highest marginal rate of federal income and employment taxation in the calendar year in which the Executive’s termination of employment occurs and state and local income taxes at the highest marginal rate of taxation in the state and locality of the Executive’s primary residence on the date of Executive’s termination of employment, net of the maximum reduction in federal income taxes that may be obtained from the deduction of such state and local taxes in such year;

(4)

Fourth, add the Single Sum Amount and the Gross-Up Amount to determine the Single Sum Pension Plan Supplement; and

(5)

Fifth, the Single Sum Pension Plan Supplement payable to the Executive shall be reduced by the cash surrender value (determined as of the date immediately prior to payment under Subsection (e)) of any pre-retirement, collateral assignment, split-dollar life insurance policies issued to the Executive under the A. O. Smith Corporation Executive Life Insurance Plan prior to August 1, 2002.

(c) Early Retirement Benefit. If an Executive described in subsection (a) terminates employment on or after his Early Retirement Age, at a time when he is not eligible for the benefit described in subsection (b), then the amount of the Single Sum Pension Plan Supplement shall be determined as follows:

(1)

First, calculate a monthly amount payable in a single life annuity form (assuming benefits commence at the Executive’s Special Early Retirement Age) equal to:

(A)

1.65% of the Executive’s Average Monthly Earnings multiplied by the number of years of Credited Service (as defined in the Pension Plan), but not more than forty (40) years;

(B)

minus the total monthly retirement benefit actually payable to the Executive from the Pension Plan as of the Executive’s Special Early Retirement Age (the result, the “Monthly Benefit Amount”);

(C)

minus the federal, stale and local income and employment taxes that would be owed by the Executive on the Monthly Benefit Amount, calculated assuming the Executive pays taxes at the highest marginal tax rates for federal, state and local income tax purposes, based on the location of the Executive’s primary residence at the time of his termination of employment (the result, the “After-Tax Monthly Benefit Amount”);

(2)

Second, multiply the After-Tax Monthly Benefit Amount by the Annuity Factor for an annuity that commences benefit payments at the Executive’s Special Early Retirement Age (the result, the “Single Sum Amount”);

(3)

Third, determine the present value of the Single Sum Amount (assuming the Single Sum Amount is payable at the Executive’s Special Early Retirement Age) using the Applicable Interest Rate, as of the Executive’s date of termination of employment;

(4)

Fourth, determine an additional amount such that the net amount retained by the Executive, after payment of any federal, state or local income tax or employment tax with respect to the Single Sum Amount, and any federal, state and local income tax or employment tax upon the payment provided for by this clause, is equal to the Single Sum Amount (the “Gross-Up Amount”). For purposes of determining the Gross-Up Amount, the Company shall use the highest marginal rate of federal income and employment taxation in the calendar year in which the Executive’s termination of employment occurs and state and local income taxes at the highest marginal rate of taxation in the state and locality of the Executive’s primary residence on the date of Executive’s termination of employment, net of the maximum reduction in federal income taxes that may be obtained from the deduction of such state and local taxes in such year;

(5)

Fifth, add the Single Sum Amount and the Gross-Up Amount to determine the Single Sum Pension Plan Supplement; and

(6)

Sixth, the Single Sum Pension Plan Supplement payable to the Executive shall be reduced by the cash surrender value (determined as of the date immediately prior to payment under Subsection (e)) of any pre-retirement, collateral assignment, split-dollar life insurance policies issued to the Executive under the A. O. Smith Corporation Executive Life Insurance Plan prior to August 1, 2002.

(d) Other Termination Benefit. If an Executive described in subsection (a) terminates employment from the Company and its Affiliates prior to his Early Retirement Age, then the amount of the Single Sum Pension Plan Supplement shall be determined as follows:

(1)

First, calculate a monthly amount payable in a single life annuity form (assuming benefits commence at the Executive’s Normal Retirement Age) equal to:

(A)

1.65% of the Executive’s Average Monthly Earnings multiplied by the number of years of Credited Service (as defined in the Pension Plan), but not more than forty (40) years;

(B)

minus the total monthly retirement benefit actually payable to the Executive from the Pension Plan as of the Executive’s Normal Retirement Age (the result, the “Monthly Benefit Amount”);

(C)

(2)

Second, multiply the After-Tax Monthly Benefit Amount by the Annuity Factor for an annuity that commences benefit payments at the Executive’s Normal Retirement Age (the result, the “Single Sum Amount”);

(3)

Third, determine the present value of the Single Sum Amount (assuming the Single Sum Amount is payable at the Executive’s Normal Retirement Age) using the Applicable Interest Rate, as of the date of the Executive’s termination of employment;

(4)

(5)

Fifth, add the Single Sum Amount and the Gross-Up Amount to determine the Single Sum Pension Plan Supplement; and

(6)

(e) Timing and Form of Payment. The Single Sum Pension Plan Supplement shall be paid to the Executive on the first day of the seventh month following the month in which the Executive’s Separation from Service occurs. Payment shall be made in: (i) cash; (ii) by the transfer of any endorsement split-dollar life insurance policies on the Executive’s life (which shall be deemed to have a value equal to the cash surrender value that Executive is entitled to receive under such policy on the date of transfer); (iii) the release of the Company’s premium interest in any collateral assignment, split-dollar life insurance policies issued to the Executive under the A. O. Smith Corporation Executive Life Insurance Plan prior to August 1, 2002; or (iv) any combination of (i), (ii) or (iii) as the Company determines in its sole discretion.

(f) Death Benefit. In no event shall a benefit be paid under this Plan if an Executive dies while in the employment of the Company. If the Executive dies after Separation from Service and prior to the date the Single Sum Pension Payment is paid, the Company shall pay to the Executive’s Beneficiary, as soon as practicable but no later than ninety (90) days following the Executive’s death, a single sum amount equal to the Single Sum Pension Supplement reduced by the death benefits, if any, payable to Executive’s Beneficiary under a split-dollar life insurance policy on Executive’s life. In the event of the death of the Beneficiary prior to receipt of the death benefit described hereinabove, such death benefit shall be paid to the Beneficiary’s estate.

Section 4. Unfunded Plan

The rights of the Executive or Beneficiary under the Plan shall be solely those of an unsecured creditor of the Company. The Company shall not be required to set aside any assets with respect to the Plan and any assets actually held by the Company with reference to the Plan shall be the sole property of the Company. Neither the Executive nor an Executive’s beneficiaries, heirs, legal representatives, or assigns shall have ownership rights of any nature with respect to any assets set aside for the Plan, unless and until such time as such assets are paid over and transferred to the Executive or the Beneficiary under the terms of the Plan.

Section 5. Non-Alienation of Benefits

Neither an Executive nor his Beneficiary shall have the power to transfer, assign, anticipate or otherwise encumber in advance the payments provided in this Plan; nor shall any of said payments, nor any assets or funds of the Company or any Affiliate be subject to seizure for the payment of any of the Executive’s or his Beneficiary’s judgments, alimony or separate maintenance or be reached or transferred by operation of law in the event of the bankruptcy or insolvency of the Executive or any Beneficiary.

Section 6. Administration

The Committee shall have all such powers that may be necessary to carry out the provisions of the Plan, including without limitation, the discretionary power and authority to delegate administrative matters to other persons, to construe and interpret the Plan, to adopt and revise rules, regulations and forms relating to and consistent with the Plan’s terms, to select the actuarial factors to be used, to make all other benefit determinations, and to make any other determination which it deems necessary or advisable for the implementation and administration of the Plan. Subject to the foregoing, all decisions and determinations by the Committee shall be final, binding and conclusive as to all parties, including without limitation any Executive, any Beneficiary and all other employees and persons, unless arbitrary and capricious.

Section 7. Appeals Procedures

(a) If an Executive or Beneficiary believes he is entitled to a benefit hereunder that was not provided, the Executive or Beneficiary (hereinafter referred to as the “claimant”) shall file a written claim for such benefit with the Committee no later than one year after the claimed benefit would have initially been due and payable. If for any reason a claim for benefits under this Plan is denied by the Committee, the Committee shall deliver to the claimant a written explanation setting forth the specific reasons for the denial, pertinent references to the section of the Plan on which the denial is based, a description of such other data as may be pertinent to the claim review, and information on the procedures to be followed by the claimant in obtaining a review of his claim and his right to file a civil suit pursuant to ERISA section 502, all written in a manner calculated to be understood by the claimant. For this purpose, the claimant’s claim shall be deemed filed when presented in writing to the Committee, and the Committee’s explanation shall be in writing delivered to the claimant within ninety (90) days of the date the claim is filed.

(b) The claimant shall have sixty (60) days following his receipt of the denial of the claim to file with the Committee a written request for review of the denial. For such review, the claimant or his representative may review pertinent documents and submit written issues and comments. The Committee shall decide the issue on review and furnish the claimant with a copy of its decision within sixty (60) days of receipt of the claimant’s request for review of his claim. The decision on review shall be final and binding and in writing and shall include specific reasons for the decision, written in a manner calculated to be understood by the claimant, as well as specific references to the pertinent provisions of the Plan on which the decision is based, a statement that the claimant is entitled to receive copies of, or access to, pertinent documents, and a statement that the claimant is entitled to bring an action under ERISA section 502. If a copy of the decision is not so furnished to the claimant within such sixty (60) days, the claim shall be deemed denied on review.

Section 8. Limitation of Rights Against the Company

Participation in this Plan, or any modifications thereof, or the payments of any benefits hereunder, shall not be construed as giving to any Executive any right to be retained in the service of the Company or any Affiliate, limiting in any way the right of the

Company or any Affiliate to terminate such Executive’s employment at any time, evidencing any agreement or understanding, express or implied, that the Company or any Affiliate will employ such Executive in any particular position or at any particular rate of compensation and/or guaranteeing such Executive any right to receive any other form or amount of remuneration from the Company or any Affiliate.

Section 9. Construction

The Plan shall be construed, administered and governed in all respects under and by the laws of the State of Wisconsin, without reference to conflict of law principles thereof. Wherever any words are used herein in the masculine, they shall be construed as though they were used in the feminine for all cases where they would so apply; and wherever any words are used herein in the singular or the plural, they shall be construed as though they were used in the plural or the singular, as the case may be, in all cases where they would so apply. The words “hereof”, “herein” and “hereunder” and other similar compounds of the word “here” shall mean and refer to this entire document and not to any particular paragraph.

Section 10. Amendment or Termination of the Plan

The Committee shall have the right to amend, modify, terminate or discontinue the Plan at any time; and such action shall be final, binding and conclusive as to all parties, including any Executive, any Beneficiary thereof and all other executives and persons. Notwithstanding the foregoing, any such Committee action to terminate or discontinue the Plan or to change the payment amounts or the time and manner of payment thereof as then provided in the Plan shall not be effective and operative with respect to benefits accrued as of such date, unless and until written consent thereto is obtained from each Executive affected by such action or, if any such Executive is not then living, from the Beneficiary thereof; provided that no consent is needed of any Executive or Beneficiary for any amendment to the Plan (including amendments that affect the time and manner of payment) that the Committee deems necessary or desirable for the Plan to comply with Section 409A of the Internal Revenue Code.

(a) Upon termination of the Plan, the Committee may authorize the distribution of the Single Sum Pension Plan Supplement in a lump sum (calculated in the same manner as described in Section 3 as if the Participant’s termination of employment occurred on the date of the Plan’s termination), only in the circumstances permitted by Code Section 409A and the regulations promulgated thereunder.

Section 11. Withholding

The Company shall have the right to deduct from any payment made hereunder, or from any other amount due an Executive, the amount necessary to satisfy the Company’s or Affiliate’s foreign, federal, state or local income tax withholding obligations with respect to the accrual or vesting of any amount, or the payment of any benefit, hereunder. In addition, if prior to the date of payment of any amount hereunder, the Federal Insurance Contributions Act (FICA) tax imposed under Code Sections 3101, 3121(a) and 3121(v)(2), where applicable, becomes due, the Participant’s Single Sum Pension Plan Supplement shall be reduced by the amount needed to pay the Participant’s portion of such tax, plus an amount equal to the withholding taxes due under federal, state or local law

resulting from the payment of such FICA tax, and an additional amount to pay the additional income tax at source on wages attributable to the pyramiding of the Code Section 3401 wages and taxes, but no greater than the aggregate of the FICA tax amount and the income tax withholding related to such FICA tax amount.

Section 12. Relationship to Employment Agreements

Except as otherwise expressly provided herein, the Plan does not affect the rights of the Executive under any employment or other compensation agreement with the Company or an Affiliate covering an Executive.

Section 13. Successors and Assigns

The terms and conditions of the Plan, as amended and in effect from time to time, shall be binding upon the successors and assigns of the Company, including without limitation any entity into which the Company may be merged or with which the Company may be consolidated.

This letter confirms our agreement to amend your offer letter dated September 20, 2004 (“Offer Letter”) with respect to your pension supplement. To resolve an open issue dating back to your date of hire related to pension forfeited at your former company, the following replaces item 4, Pension Supplement, in your Offer Letter:

Pension Supplement. With completion of 10 years of service with A. O. Smith, you will be eligible for an $85,000/year supplement paid as a straight life annuity commencing with your retirement from A. O. Smith.

If you have any questions about this, please feel free to contact me.

Best Regards,

/s/ Mark A. Petrarca
