Organization and Significant Accounting Policies

1.	Organization and Significant Accounting Policies

Organization. A. O. Smith Corporation (A. O. Smith or the company) is a manufacturer of water heaters and boilers, serving a diverse mix of residential and commercial end markets principally in the United States with a strong and growing international presence. The company is comprised of two reporting segments: North America and Rest of World. The Rest of World segment is primarily comprised of China, India and Europe. Both segments manufacture and market comprehensive lines of residential gas, gas tankless and electric water heaters and commercial water heating equipment. Both segments primarily serve their respective regions of the world. The North America segment also manufactures and markets specialty commercial water heating equipment, condensing and non-condensing boilers and water system tanks. The Rest of World segment also manufactures and markets water treatment products, primarily in Asia.

On August 22, 2011, the company sold its Electrical Products business (EPC) to Regal Beloit Corporation (RBC) for approximately $760 million in cash and approximately 2.83 million shares of RBC common stock. Due to the sale, EPC has been reported separately as a discontinued operation. See Note 2 Discontinued Operations.

Consolidation. The consolidated financial statements include the accounts of the company and its wholly owned subsidiaries after elimination of intercompany transactions.

Except when otherwise indicated, amounts reflected in the financial statements or the notes thereto relate to the company’s continuing operations.

Use of estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States (U.S.) requires management to make estimates and assumptions that affect the amounts reported in the accompanying financial statements and notes. Actual results could differ from those estimates.

Fair value of financial instruments. The carrying amounts of cash, cash equivalents, marketable securities, receivables, investments, floating rate debt and trade payables approximated fair value as of December 31, 2012 and 2011, due to the short maturities or frequent rate resets of these instruments. The fair value of term notes with insurance companies was approximately $86.6 million as of December 31, 2012 compared with the carrying amount of $80.0 million for the same date. The fair value is estimated based on current rates offered for debt with similar maturities.

Foreign currency translation. For all subsidiaries outside the U.S., with the exception of its Mexican operation, two of its Chinese non-operating companies, and a Dutch non-operating company the company uses the local currency as the functional currency. For those operations using a functional currency other than the U.S. dollar, assets and liabilities are translated into U.S. dollars at year-end exchange rates, and revenues and expenses are translated at weighted-average exchange rates. The resulting translation adjustments are recorded as a separate component of stockholders’ equity. The Mexican operation, the two Chinese non-operating companies and the Dutch non-operating company use the U.S. dollar as the functional currency. 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.

Marketable securities. The company considers all highly liquid investments with maturities greater than 90 days when purchased to be marketable securities. At December 31, 2012, the company’s marketable securities consisted of bank time deposits with original maturities ranging from 180 days to 12 months and are located at investment grade rated banks in China.

Inventory valuation. Inventories are carried at lower of cost or market. Cost is determined on the last-in, first-out (LIFO) method for a majority of the company’s domestic inventories, which comprise 64 percent and 65 percent of the company’s total inventory at December 31, 2012 and 2011, respectively. Inventories of foreign subsidiaries and supplies are determined using the first-in, first-out (FIFO) method.

Property, plant and equipment. Property, plant and equipment are stated at cost. Depreciation is computed primarily by the straight-line method. The estimated service lives used to compute depreciation are generally 25 to 50 years for buildings, three to 20 years for equipment and three to seven years for software. Maintenance and repair costs are expensed as incurred.

Goodwill and other intangibles. Goodwill and indefinite-lived intangible assets are not amortized but are reviewed for impairment on an annual basis. Separable intangible assets primarily comprised of customer relationships that are not deemed to have an indefinite life are amortized on a straight-line basis over their estimated useful lives which range from ten to 25 years.

Impairment of long-lived and amortizable intangible assets. Property, plant and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset or group of assets, a loss is recognized for the difference between the fair value and carrying value of the asset or group of assets. Such analyses necessarily involve significant judgment.

Derivative instruments. Accounting Standards Codification (ASC) 815 Derivatives and Hedging (formerly Statement of Financial Standards No. (SFAS) 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. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as a part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, the company must designate the hedging instrument, based upon the exposure hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation.

The company designates that all of its hedging instruments, except for its equity collar contract relating to shares of RBC common stock, are cash flow hedges. For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive loss, net of tax, and is reclassified into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. The amount by which the cumulative change in the value of the hedge more than offsets the cumulative change in the value of the hedged item (i.e., the ineffective portion) is recorded in earnings, net of tax, in the period the ineffectiveness occurs.

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

Foreign Currency Forward Contracts

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

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 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 and all of the hedges will be reclassified into earnings no later than December 2013. Contracts related to the company’s discontinued operation that were to expire after the expected closing date no longer qualified for hedge accounting; therefore, the change in valuation from the announcement of the sale to August 22, 2011 of $3.2 million and $0.4 million were recorded in earnings from discontinued operations in the years ended December 31, 2011 and 2010, respectively.

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


December 31 (dollars in millions)	2012				2011
	Buy		Sell		Buy		Sell
British pound	$	—	$	2.3	$	—	$	—
Canadian dollar		—		36.8		—		36.6
Euro		23.2		2.0		16.1		1.2
Mexican peso		12.3		—		16.5		—

Total	$	35.5	$	41.1	$	32.6	$	37.8

Commodity Futures Contracts

In addition to entering into supply arrangements in the normal course of business, the company, primarily for its discontinued operation prior to disposition, also entered 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 hedging strategy for achieving this objective is to purchase commodities futures contracts on the open market of the London Metals Exchange (LME) or over the counter contracts based on the LME.

With one of its brokers, the company is required to make cash deposits on unrealized losses on commodity derivative contracts that exceed $10.0 million.

The minimal after-tax gain of the effective portion of the contracts as of December 31, 2012 was recorded in accumulated other comprehensive loss, and will be reclassified into cost of products sold in the period in which the underlying transaction is recorded in earnings. The effective portion of the contracts will be reclassified within one year. Contracts related to the company’s discontinued operation that expired after the expected closing date no longer qualified for hedge accounting; therefore the change in valuation from the announcement of the sale to August 22, 2011 was minimal and was recorded in earnings from discontinued operations in the years ended December 31, 2011 and 2010, respectively. Commodity hedges outstanding at December 31, 2012 total approximately 0.2 million pounds of copper.

Equity Collar Contract

As discussed in Note 2, on August 22, 2011, the company sold EPC to RBC and received approximately 2.83 million shares of RBC common stock. The RBC share price appreciated in the first quarter of 2011 during which the company entered into an equity collar contract for 50 percent of the RBC shares to protect a portion of that appreciation. The put strike price of the equity collar was $63.29 and the call strike price of the collar was $77.32. The RBC share price on December 31, 2011 was $50.97. The collar did not qualify for hedge accounting and therefore was adjusted to fair value on a quarterly basis through earnings from continuing operations. The company was required to make cash or stock deposits on unrealized losses on the equity collar that exceeded $25.0 million. The mark to market accounting for the RBC shares and hedge continued until the equity collar contract expired in March 2012 with no value.

The impact of derivative contracts on the company’s financial statements is as follows (dollars in millions):

Fair Value Measurements. The company adopted ASC 820 Fair Value Measurements and Disclosures (formerly SFAS 157) on January 1, 2008. ASC 820, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Assets and liabilities measured at fair value are based on the market approach which are prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

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


Fair Value Measurement Using	December 31, 2012		December 31, 2011
Quoted prices in active markets for identical assets (Level 1)	$	197.2	$	144.2
Significant other observable inputs (Level 2)		—		17.8

Total investments and net derivative contracts	$	197.2	$	162.0

There were no changes in our valuation techniques used to measure fair values on a recurring basis as a result of adopting ASC 820.

Revenue recognition. The company recognizes revenue upon transfer of title, which occurs upon shipment of the product to the customer except for certain export sales where transfer of title occurs when the product reaches the customer destination.

Contracts and customer purchase orders are used to determine the existence of a sales arrangement. Shipping documents are used to verify shipment. The company assesses whether the selling price is fixed or determinable based upon the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. The company assesses collectability based on the creditworthiness of the customer as determined by credit checks and analysis, as well as the customer’s payment history, and does not require collateral on sales in most cases. The allowance for doubtful accounts was $4.2 million and $3.4 million at December 31, 2012 and 2011, 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. The majority of advertising costs are charged to operations as incurred and amounted to $69.2 million, $58.9 million and $47.9 million during 2012, 2011 and 2010, respectively. Included in total advertising costs are expenses associated with store displays for A. O. Smith branded products in China that are amortized over 12 to 24 months which totaled $15.8 million, $13.1 million and $9.2 million during 2012, 2011 and 2010, respectively.

Research and development. Research and development costs are charged to operations as incurred and amounted to $51.7 million, $42.7 million and $37.1 million during 2012, 2011 and 2010, 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 2012 and 2011:


Years ended December 31 (dollars in millions)	2012			2011
Balance at beginning of year	$	131.8		$	112.2
Lochinvar acquisition (see Note 3)		—			5.8
Expense		54.1			64.6
Net increase in warranty reserve due to settlement		—			7.5
Claims settled		(56.3	)		(58.3	)

Balance at end of year	$	129.6		$	131.8

See Note 4 for discussion on the increase in warranty reserve due to settlement and the increase in warranty expense and reserve associated with component issues with a supplier for the company’s Canadian operations.

Environmental costs. The company accrues for costs associated with environmental obligations when such costs are probable and reasonably estimable. Costs of estimated future expenditures are not discounted to their present value. Recoveries of environmental costs from other parties are recorded as assets when their receipt is considered probable. The accruals are adjusted as facts and circumstances change.

Stock-based compensation. The company follows ASC 718 Compensation – Stock Compensation (formerly SFAS 123(R)). Compensation cost is recognized using the straight-line method over the vesting period of the award. ASC 718 also requires the benefits of tax deductions in excess of recognized compensation 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 $8.8 million, $4.3 million and $0.7 million were recognized cash flows provided by financing activities in 2012, 2011 and 2010, respectively.

Earnings per share of common stock. The company is not required to use the two-class method of calculating earnings per share since its Class A Common Stock and Common Stock have equal dividend rights. The numerator for the calculation of basic and diluted earnings per share is net earnings. The following table sets forth the computation of basic and diluted weighted-average shares used in the earnings per share calculations:


	2012		2011		2010
Denominator for basic earnings per share – weighted-average shares outstanding		46,197,608		46,119,032		45,743,246
Effect of dilutive stock options, restricted stock and share units		356,453		455,586		419,469

Denominator for diluted earnings per share		46,554,061		46,574,618		46,162,715

On October 11, 2010, the company’s board of directors declared a three-for-two stock split of the company’s Class A Common Stock and Common Stock in the form of a 50 percent stock dividend to stock holders of record on October 29, 2010 and payable on November 15, 2010. Shares held in treasury by the company were not impacted by the split. All references in the financial statements to number of shares outstanding, price per share, per share amounts and stock based compensation data have been retroactively restated to reflect the split for all periods presented.

Reclassifications. Certain amounts from prior years have been reclassified to conform with current year presentation.

Recent Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-08, “Testing of Goodwill for Impairment (Topic 350)”. ASU No. 2011-08 allows companies to assess qualitative factors to determine whether the two-step quantitative goodwill impairment test needs to be performed. Under the option, an entity no longer would be required to calculate the fair value of a reporting unit unless it determines, based on that qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The ASU may change how a company tests goodwill for impairment, but should not change the timing or measurement of goodwill impairments. ASU 2011-08 was effective for the year ended December 31, 2012. Adoption of this ASU did not have an impact on the company’s consolidated financial condition, results of operations or cash flows.

In July 2012, the FASB issued ASU 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment.” ASU 2012-02 allows an entity to first assess qualitative factors in determining whether events and circumstances indicate that it is more-likely-than not that an indefinite-lived intangible asset is impaired. If an entity determines that it is not more-likely-than not that the indefinite-lived intangible asset is impaired, then the entity is not required to perform a quantitative impairment test. ASU 2012-02 will be effective for the year ending December 31, 2013. Adoption of this ASU will not have an impact on the company’s consolidated financial condition, results of operations or cash flows.

Discontinued Operations

2.	Discontinued Operations

On August 22, 2011, the company completed the sale of EPC to RBC for $759.9 million in cash and approximately 2.83 million shares of RBC common stock. Included in the $759.9 million of cash is a final working capital adjustment of $7.4 million which was paid to the company by RBC in January 2012. The value of the RBC shares on the date of the closing of the sale was $140.6 million. See Note 13 for further discussion regarding the company’s investment in RBC stock. In 2012, the company paid $31.2 million in income taxes and $3.6 million of other sale related payments. In 2011, the company paid $126.5 million in income taxes and $21.4 million in commissions and other sale related payments.

Included in the 2011 gain on sale of EPC was an additional income tax accrual due to the company’s assertion that certain foreign earnings derived from the sale of EPC were not considered permanently reinvested by the company. The accrual is included in long term deferred income taxes in continuing operations. Also included in the 2011 gain on sale is a $10.9 million gain related to cumulative translation adjustments associated with EPC’s foreign subsidiaries. In the fourth quarter of 2012, the company recorded expense of $3.9 million on the gain on sale of EPC. Included in 2012 was $6.4 million of expense representing the correction of an error primarily due to the company’s calculation of taxes due upon repatriation of undistributed foreign earnings. The correction was not material to any previously reported financial period or to the year ended December 31, 2012 and as a result has been reported as the correction of the error in the year ended December 31, 2012. This correction was offset by a change in estimate related to other reserves associated with EPC of $2.5 million.

The results of EPC including all prior years have been reported separately as discontinued operations.

The components of the net assets of EPC discontinued operations were current liabilities-net of $3.1 million and $31.5 million in 2012 and 2011, respectively and long-term liabilities-net of $7.8 million and $8.7 million in 2012 and 2011, respectively related to discontinued EPC operations consisting primarily of certain retained product liabilities, employee obligations such as workers’ compensation and disability and income tax liabilities associated with EPC.

Acquisitions

3.	Acquisitions

On August 26, 2011, the company acquired 100 percent of the shares of Lochinvar Corporation (Lochinvar), a privately held manufacturer of high-efficiency boilers used in commercial and residential applications located in Lebanon, Tennessee. The addition of Lochinvar expanded the company’s product offerings and gave the company access to proven high-efficiency boiler technology. Results from Lochinvar are included in the North America segment except for a relatively immaterial amount from a Lochinvar subsidiary in the United Kingdom which is in the company’s Rest of World segment.

The company paid an aggregate cash purchase price, net of $1.5 million of cash acquired, of $421.1 million. In addition, the company incurred acquisition costs of approximately $5.5 million. Under the purchase agreement for the Lochinvar acquisition, the company agreed to make a contingent payment of up to an additional $35.0 million in cash based on the amount by which Lochinvar sales between December 1, 2011 and November 30, 2012 exceed $216.0 million. As of the acquisition date and December 31, 2011, the fair value of the contingent payment had been estimated at $16.8 million. In December 2012, the contingent payment totaling $13.5 million was made to the former owners of Lochinvar. The contingent consideration adjustment of $3.3 million was recognized as pre-tax earnings in 2012.

The following table summarizes the allocation of fair value of the assets acquired and liabilities assumed at the date of acquisition. Of the $258.3 million of acquired intangible assets, $103.5 million has been assigned to tradenames that are not subject to amortization and $152.5 million has been assigned to customer lists which are being amortized over 19 years, and the remaining $2.3 million has been assigned to non-compete agreements and patents which are being amortized over ten years.


August 26, 2011 (dollars in millions)
Current assets, net of cash acquired	$	54.0
Property, plant and equipment		41.9
Intangible assets		258.3
Other assets		0.1
Goodwill		111.4

Total assets acquired		465.7
Current liabilities		24.3
Long-term liabilities		3.5

Total liabilities assumed		27.8

Net assets acquired	$	437.9

For income tax purposes, the transaction has been accounted for as an asset purchase, resulting in the full amount of goodwill and intangible assets, totaling $369.7 million, being deductible for income tax purposes.

Lochinvar’s results of operations have been included in the company’s financial statements from August 26, 2011, the date of acquisition. Revenues and pre-tax earnings associated with Lochinvar in 2012 were $225.7 million and $51.1 million, respectively. Revenues and pre-tax earnings associated with Lochinvar included in operations from the acquisition date through December 2011 totaled $75.9 million and $5.6 million, respectively which included $13.0 million of operating earnings less $5.5 million of acquisition costs included in selling, general and administrative expense and $1.9 million of interest expense.

The following table represents the pro forma unaudited results of continuing operations for the company for the years ended December 31, 2011 and 2010, respectively, assuming consummation of the purchase of Lochinvar as of January 1 of each year. (dollars in millions except per share data):


	Years ended December 31,
	2011		2010
Net sales	$	1,835.8	$	1,664.0
Earnings from continuing operations		122.5		71.5
Earnings per common share:
Basic	$	2.66	$	1.56

Diluted	$	2.63	$	1.55

The pro forma results have been prepared for informational purposes only and include adjustments to depreciation expense of acquired plant and equipment, amortization of intangible assets other than goodwill and tradenames, increased interest expense on acquisition related debt, and certain other adjustments, together with related income tax effects of such adjustments. These pro forma results do not purport to be indicative of the results of operations that would have occurred had the purchases been made as of the beginning of the periods presented or of the results of operations that may occur in the future.

In November 2009, the company acquired a majority interest in the water treatment business of Tianlong Holding Co. Ltd. (Tianlong) of Hong Kong, with operations based in Shanghai, China. A newly formed company, A. O. Smith (Shanghai) Water Treatment Products Co., Ltd. (SWT), holds the assets of the business, which manufactures and supplies reverse osmosis units and other water treatment products to the China residential and commercial markets as well as export markets around the world.

The company acquired an 80 percent interest in SWT at a total cost of $76.7 million, including fixed future payments of $5.7 million, subject to reductions for claims the company could make if there are any breaches of the representations and warranties made by the selling shareholder under the acquisition agreement. As required under ASC 805 the company recorded 100 percent of the fair value of the assets and liabilities as of the date of acquisition, with the 20 percent noncontrolling interest recorded in the equity section of the company’s balance sheet. The acquisition value exceeded the fair value of the assets acquired by $90.6 million, of which $55.4 million was recorded as goodwill and $42.2 million was recorded as intangible assets in the Rest of World segment. In addition, $7.0 million of deferred tax liabilities associated with the intangible assets were recorded. In 2010, the company made a goodwill adjustment of $1.1 million related to an inventory valuation. The company purchased the remaining 20 percent interest in SWT for $6 million from the former owner in the fourth quarter of 2010. The difference between the amount paid and the carrying value of the noncontrolling interest was recorded to additional paid-in capital. The $5.7 million future payment mentioned above was not paid due to breaches of representations and warranties and was recognized as a gain as part of a settlement with the former owner (see Note 4).

In July 2010, the company purchased the U.S. assets and the right to market and sell tankless water heaters in North America from Takagi Industrial Co, Ltd (Takagi) of Fuji-city, Shizuoka, Japan for $5.5 million. Through the venture, the company offers a full line of tankless water heaters under its own brands in association with the Takagi brand. The company’s Takagi activity is included in the North America segment.

In the fourth quarter of 2010, the company purchased the remaining 50 percent share of its China joint venture that manufactures combi-boilers for the residential market in China for $0.3 million. The joint venture was formed in December, 2007.

The acquisitions were accounted for under the purchase accounting method, and accordingly, the results of operations are included in the company’s financial statements from the date of acquisition.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Restructuring, Impairment and Settlement Income, Net

On November 15, 2012, the company entered into an agreement settling a legal action that had commenced on June 14, 2011, in the United States District Court for the Eastern District of Missouri seeking recovery of costs and damages due to an issue in the company’s Canadian operations with a component part supplied by a vendor. In the fourth quarter of 2012, the company recorded a pre-tax gain of $3.9 million relating to the settlement. In the second quarter of 2011, the company recorded an $8.2 million warranty provision for future costs associated with this issue. This activity is included in the North America segment.

On May 5, 2011, the company entered into an agreement settling a legal action that the company commenced on June 30, 2009, in Tennessee State Court, seeking recovery for costs and damages due to an issue in the company’s U.S. operations with a component part supplied by the vendor. Under the terms of the settlement agreement, the vendor and the vendor’s supplier made a $35.5 million cash payment to the company. The settlement reimbursed the company for past costs previously incurred and satisfied in full a receivable recorded by the company, and the company increased its warranty reserve for future costs associated with the affected components on company products by $7.5 million. In the second quarter of 2011, the company recorded a pre-tax gain of $11.2 million for the reimbursement of related costs incurred in prior years. This activity is included in the North America segment.

In 2010, the company recognized a $3.3 million impairment charge related to SWT’s trademarks. The company announced plans to move the water treatment operations to Nanjing, China to recognize synergies associated with the company’s strong management team and the engineering center in place at the company’s water heater operations in that city. A restructuring charge of $1.8 million was recognized relative to the move for severance, lease termination and asset impairment costs. The charges were largely offset by a $5.0 million gain on settlement of disputes with the prior owner relative to breaches of representations and warranties regarding the condition of SWT on the date of purchase. This activity is included in Rest of World segment.

Amortization of other intangible assets of $14.6 million, $9.6 million, and $7.1 million was recorded in 2012, 2011 and 2010, respectively. In the future, the company expects amortization to approximate $14.7 million annually and the intangible assets will be amortized over a weighted average period of 16 years.

As a result of the sale of EPC and change in management reporting, the company reconsidered its segment reporting in the fourth quarter of 2011. These changes did not have a significant impact on how the company evaluates goodwill or other intangible assets for impairment. The company concluded that no goodwill impairment existed at the time of the annual impairment tests which were performed in the fourth quarters of 2012, 2011 and 2010. No impairments of other intangible assets were recorded in 2012 and 2011. In 2010, the company recognized an intangible asset impairment charge related to SWT of $3.3 million (see Note 4).

The facility has an accordion provision which allows it to be increased up to $500 million if certain conditions (including lender approval) are satisfied.

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, 2012 and 2011. At its option, the company maintains either cash balances or pays fees for bank credit and services.

Stock Based Compensation

11.

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. At the company’s annual meeting of stockholders on April 14, 2009, an amendment to the plan was approved to increase the authorized shares of Common Stock under the plan by 1,875,000. The number of shares available for granting of options or share units at December 31, 2012, was 1,633,354. Upon stock option exercise, restricted stock grant, or share unit vesting, shares are issued from Treasury stock.

Total stock based compensation cost recognized in 2012, 2011 and 2010 was $6.8 million, $5.7 million and $5.4 million, respectively.

Stock options

The stock options granted in 2012, 2011 and 2010 have a three year pro rata vesting from the date of grant. Stock options are issued at exercise prices equal to the fair value of Common Stock on the date of grant. For active employees, all options granted in 2012, 2011 and 2010 expire ten years after date of grant. Stock option compensation recognized in 2012, 2011 and 2010 was $3.2 million, $2.8 million and $2.2 million, respectively. Included in the stock option expense recognized in 2012, 2011 and 2010 is expense associated with the accelerated vesting of stock option awards for certain employees who either are retirement eligible or become retirement eligible during the vesting period.

Changes in option shares, all of which are Common Stock, were as follows:


	Weighted-Avg. Per Share		Years Ended December 31									(dollars in millions) Aggregate Intrinsic Value
	Weighted-Avg. Per Share		Years Ended December 31
	Exercise Price		2012			2011			2010

2012—$27.93 to $45.97 per share				(4,083	)
2011—$19.00 to $43.12 per share							(15,353	)
2010—$19.00 to $27.93 per share										(3,849	)

Outstanding at end of year
(2012—$15.99 to $45.97 per share)		33.43		765,367			1,421,867			1,623,101

Exercisable at end of year		26.05		409,656			989,933			951,035

The aggregate intrinsic value for the outstanding and exercisable options as of December 31, 2012 is $22.7 million and $15.2 million, respectively. The average remaining contractual life for outstanding and exercisable options is eight years and seven years, respectively.

The following table summarizes weighted-average information by range of exercise prices for stock options outstanding and exercisable at December 31, 2012:


Range of Exercise Prices	Options Outstanding at December 31, 2012		Weighted- Average Exercise Price		Options Exercisable at December 31, 2012		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Life
$15.99 to $19.47		142,000	$	18.60		142,000	$	18.60		7 years
$21.34 to $24.02		48,001		23.76		48,001		23.76		6 years
$25.84 to $45.97		575,366		37.90		219,655		31.37		9 years

		765,367				409,656

The weighted-average fair value per option at the date of grant during 2012, 2011 and 2010, using the Black-Scholes option-pricing model, was $16.52, $16.51 and $10.19, respectively. Assumptions were as follows:


	2012			2011			2010
Expected life (years)		6.2			6.4			6.4
Risk-free interest rate		2.0	%		3.6	%		3.6	%
Dividend yield		1.4	%		1.3	%		1.9	%
Expected volatility		39.4	%		38.4	%		38.7	%

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 83,930, 75,625 and 101,873 share units under the plan in 2012, 2011 and 2010, respectively. Compensation expense was recognized ratably over the vesting period.

The share units were valued at $3.9 million, $3.3 million and $2.9 million at the date of issuance in 2012, 2011 and 2010, respectively, and will be recognized as compensation expense ratably over the three-year vesting period. Compensation expense of $3.6 million, $2.9 million and $3.2 million was recognized in 2012, 2011 and 2010, respectively. Included in share based compensation is expense associated with the accelerated vesting of share unit awards for certain employees who either are retirement eligible or become retirement eligible during the vesting period.

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


	Number of Units			Weighted-Average Grant Date Value
Outstanding at January 1, 2012		286,554		$	27.36
Granted		83,930			45.97
Vested		(132,974	)		18.80
Forfeited/cancelled		(3,004	)		37.42

Outstanding at December 31, 2012		234,506		$	38.74

Total compensation expense for share units not yet recognized is $2.7 million at December 31, 2012. The weighted average period over which the expense is expected to be recognized is 17 months.

Pension and Other Post-retirement Benefits

12 Months Ended

Dec. 31, 2012

Pension and Other Post-retirement Benefits

12.

Pension and Other Post-retirement Benefits

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

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

The company also has a defined benefit plan for salaried employees and its non-union hourly workforce. In the fourth quarter of 2009, the company announced employees hired after January 1, 2010, will not participate in the defined benefit plan, and benefit accruals for the majority of current salaried and non-union hourly employees will stop at the end of 2014. This change resulted in a plan curtailment and reduced the plan’s liability by $12.3 million. No curtailment gain was recognized because the reduction in liability was offset by existing unrecognized losses. An additional company contribution will be made to the defined contribution plan in lieu of participation in a defined benefit plan. The company also has defined benefit and contribution plans for certain union hourly employees.

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

The estimated net actuarial loss and prior service cost for the pension plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2013 are $41.7 million and $(0.9) 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 2013 are each less than $0.3 million. As permitted under ASC 715 (formerly SFAS 87 and paragraph 53 of SFAS 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 2012 and 2011 after tax adjustments for additional minimum pension liability resulted in other comprehensive loss of $22.4 million and $54.5 million, respectively.

*	Includes $(1.6) million and $0 million of defined benefit plan (expense) income and $0.9 million and $1.2 million of defined contribution plans expense that were included in earnings from discontinued operations for 2011 and 2010, respectively.

Assumptions

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


	Pension Benefits						Post-retirement Benefits
	2012			2011			2012			2011
Discount rate		4.05	%		4.90	%		4.05	%		4.90	%
Average salary increases		4.00	%		4.00	%		4.00	%		4.00	%

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	2012			2011			2010			2012			2011			2010
Discount rate		4.90	%		5.35	%		5.80	%		4.90	%		5.35	%		5.80	%
Expected long-term return on plan assets		8.50	%		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	%

In developing the expected long-term rate of return assumption, the company evaluated its pension plan’s target and actual asset allocation and expected long-term rates of return of equity and bond indices. The company also considered its pension plan’s historical ten-year and 25-year compounded annualized returns of 7.6 percent and 9.8 percent, respectively.

Assumed health care cost trend rates

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


	2012			2011
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		2017			2016

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	2012			2011
Equity securities		62	%		55	%
Debt securities		33			37
Private equity		4			5
Other		1			3

		100	%		100	%

Balance at December 31, 2012	$	23.3		$	0.3	$	34.4		$	58.0

The company’s investment policies employ an approach whereby a diversified blend of equity and bond investments is used to maximize the long-term return of plan assets for a prudent level of risk. Equity investments are diversified across domestic and non-domestic stocks, as well as growth, value, and small to large capitalizations. Bond investments include corporate and government issues, with short-, mid- and long-term maturities, with a focus on investment grade when purchased. The company’s current allocation to equity managers is between 60 to 65 percent with the remainder allocated primarily to bonds and a small allocation to private equity managers and cash. Investment and market risks are measured and monitored on an ongoing basis through regular investment portfolio reviews, annual liability measurements and periodic asset/liability studies.

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

There was no company stock included in plan assets at December 31, 2012.

Cash Flows

The company was not required to and did not make any contributions in 2012 and is not required to make a contribution in 2013.

Estimated Future Payments

The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid:


Years ending December 31 (dollars in millions)	Pension Benefits		Post-retirement Benefits
2013	$	60.4	$	0.9
2014		59.8		0.8
2015		65.4		0.8
2016		60.9		0.8
2017		64.7		0.8

Investment in Shares of RBC Common Stock

13.

Investment in Shares of RBC Common Stock

As discussed in Note 2, the company received approximately 2.83 million shares of RBC common stock as part of the proceeds of its sale of EPC to RBC. The value of those shares at December 31, 2011 was $144.4 million. One half of the company’s shares of RBC common stock were classified as available for sale securities and were recorded at fair value with an unrealized after-tax gain of $1.2 million included in other comprehensive earnings as of December 31, 2011. The company entered into an equity collar contract for the remaining half of its shares of RBC common stock which were classified as trading securities. Those shares were also recorded at fair value. See Note 1 for further discussion regarding the equity collar. During the first quarter of 2012, the company sold all of its shares of RBC common stock for net proceeds of $187.6 million or an average price of $66.19 per share. Net pre-tax gains of $27.2 million were recorded in other (income) expense-net in the consolidated statement of earnings in the first quarter of 2012. The net pre-tax $27.2 million gain was comprised of $43.2 million of gains on the sale of the shares of RBC common stock, the recognition of a $1.9 million gain previously recognized in other comprehensive loss at December 31, 2011 and the write off of $17.9 million, the value of the collar at December 31, 2011. The $187.6 million of net proceeds received in 2012 were used to pay down debt.

Ashland City, TN Facility Flood

Starting May 3, 2010, production at the company’s largest water heater manufacturing plant located in Ashland City, TN was temporarily shut down due to flooding of the Cumberland River. Water heater production was shifted to other company plants located in the United States, Canada and Mexico. The company resumed production at the Ashland City, TN plant in June 2010. The impact from the flood was essentially completed by year end 2010.

As of December 31, 2010, the company recorded flood related expense of $35.4 million, net of insurance proceeds, consisting of the following:


(dollars in millions)
Repair or write off of buildings and equipment	$	36.1
Net inventory loss		16.4
Site cleanup and restoration		14.8

		67.3
Less: insurance proceeds		31.9

Total flood related expense	$	35.4

The buildings and equipment of the Ashland City, TN plant sustained damages due to the flooding. As of December 31, 2010, restoration of manufacturing equipment was complete and office space was nearing completion. The carrying value of fixed assets destroyed in the flood was written off, totaling $14.0 million. An additional $22.1 million was expensed to repair and refurbish damaged equipment to pre-flood condition.

The net inventory loss, totaling $16.4 million, included the cost of raw materials, work-in-process and finished goods inventories that were not able to be used or sold due to flood damage.

Site cleanup and restoration began as soon as the flood waters subsided. The company engaged outside contractors to pump out water and clean and sanitize the facilities and the grounds of the manufacturing facility prior to access by company personnel. Employees normally engaged in the production of water heaters were utilized in the cleanup and repair of the facility and equipment, assessment and recovery of inventories and other aspects of the site restoration. Internal and external costs associated with site restoration and cleanup totaled $14.8 million.

Insurance proceeds

In 2010, the company maintained property damage and business interruption insurance coverage applicable to its Ashland City, TN plant totaling $30 million. The company also had federal flood insurance policies and $1.9 million was recovered. The company received total insurance proceeds of $31.9 million.

Government Assistance

In addition, the company received assistance from the State of Tennessee as well as local governmental agencies as incentive to reinvest in the Ashland City facility. Those incentives were in the form of grants, future tax credits and the purchase of certain property. The benefits, collectively, totaled approximately $7 million in 2010, of which $1.4 million of income was recorded in cost of goods sold in the third quarter of 2010. In the fourth quarter of 2010, $5.6 million was recorded including $1.3 million in cost of goods sold, $2.3 million in other income and $2.0 million as an offset to direct flood related expenses.

Income Taxes

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


Years ended December 31 (dollars in millions)	2012			2011			2010
Current:
Federal	$	51.5		$	(28.0	)	$	(2.9	)
State		7.2			(5.2	)		2.4
International		17.0			4.9			14.1

State		4.6			11.9			0.5
International		(5.3	)		3.4			(3.8	)

	$	71.2		$	50.3		$	17.3

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


Years ended December 31	2012			2011			2010
Provision at U.S. federal statutory rate		35.0	%		35.0	%		35.0	%
State income and franchise taxes, net of federal benefit		3.3			3.2			1.6
International income tax rate differential		(5.6	)		(4.3	)		(13.4	)

State tax credits		—			(2.3	)		—
Other		(0.2	)		0.1			0.5

		30.4	%		31.1	%		23.3	%

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


Years ended December 31 (dollars in millions)	2012		2011		2010
U.S.	$	158.6	$	117.8	$	12.4
International		75.2		43.7		62.0

	$	233.8	$	161.5	$	74.4

Total income taxes paid by the company including discontinued operations amounted to $103.0 million, $117.2 million, and $12.3 million in 2012, 2011 and 2010, respectively.

Included in the 2011 gain on sale of EPC was an additional income tax accrual due to the company’s assertion that certain foreign earnings derived from the sale of EPC were not considered permanently reinvested by the company. In the fourth quarter of 2012, the company recorded discontinued operations expense of $6.4 million representing the correction of an error primarily due to its calculation of taxes due upon repatriation of undistributed foreign earnings. The correction was not material to any previously reported financial period or to the year ended December 31, 2012 and as a result has been reported as the correction of an error in the year ended December 31, 2012. As of December 31, 2012, the company has $61.9 million accrued for its estimate of the tax costs due upon repatriation of undistributed foreign earnings it considers to be not permanently reinvested. At December 31, 2012, the company had undistributed foreign earnings of $663.0 million, of which $392.0 million are considered permanently reinvested. No U.S. income tax provision or foreign withholding tax provisions have been made on foreign earnings that remain permanently reinvested. Determination of the amount of unrecognized deferred tax liability on the undistributed earnings considered permanently reinvested is not practicable. In addition, no provision or benefit for U.S. income taxes has been made on foreign currency translation gains or losses. As of December 31, 2012, $457.1 million of cash and cash equivalents were held by our foreign subsidiaries.

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


December 31 (dollars in millions)
	2012					2011
	Assets			Liabilities		Assets			Liabilities
Employee benefits	$	90.2		$	—	$	71.5		$	—
Product liability and warranties		57.3			—		60.6			—
Inventories		—			2.4		—			3.3
Accounts receivable		11.2			—		9.6			—
Property, plant and equipment		—			35.7		—			35.1
Intangibles		—			32.9		—			29.1
Environmental		3.2			—		3.3			—
RBC stock and collar		—			—		—			8.5
Undistributed foreign earnings		—			65.1		—			56.5
Tax loss and credit carryovers		15.3			—		17.0			—
All other		1.5			—		0.4			—
Valuation allowance		(7.4	)		—		(8.4	)		—

	$	171.3		$	136.1	$	154.0		$	132.5

Net asset	$	35.2				$	21.5

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)	2012		2011
Current deferred income tax assets	$	33.2	$	24.6
Long-term deferred income tax (liabilities) assets		2.0		(3.1	)

Net asset	$	35.2	$	21.5

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


December 31 (dollars in millions)
	Net Operating Losses and Tax Credits						Valuation Allowances
	2012			2011			2012			2011
Beginning balance	$	17.0		$	16.0		$	8.4		$	1.9
Additions		2.0			10.3			3.0			6.6
Reductions		(3.7	)		(9.3	)		(4.0	)		(0.1	)

Ending balance	$	15.3		$	17.0		$	7.4		$	8.4

The company has foreign net operating loss carryovers that expire in 2014 through 2020, a foreign tax credit carryover that expires in 2021, and state and local net operating loss carryovers that expire between 2013 and 2030.

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


(Dollars in millions)	2012			2011
Balance at January 1	$	1.8		$	2.0
Additions based on tax positions related to the current year		—			—
Reductions for tax positions of prior years		(0.5	)		(0.2	)

Balance at December 31	$	1.3		$	1.8

The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $0.9 million. The company recognizes potential interest and penalties related to unrecognized tax benefits as a component of tax expense. At December 31, 2012 there was $0.2 million of interest and penalties accrued. It is anticipated there will be a $0.2 million decrease in total amount of unrecognized tax benefits in the next 12 months. The company’s U.S. federal income tax returns for 2008-2012 are subject to audit. The company is subject to state and local income tax audits for tax years 2000-2012. The company is subject to non-U.S. income tax examinations for years 2006-2012.

Commitments and Contingencies

The company is a potentially responsible party in 14 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 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, 2012 and 2011, 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.

Operations by Segment

Prior to the sale of EPC the company had identified two segments, Water Products Company and EPC. As a result of the sale of EPC and a change in management reporting, the company reconsidered its segment reporting in the fourth quarter of 2011 and determined that it is comprised of two reporting segments: North America and Rest of World. The Rest of World segment is primarily comprised of China, India and Europe. Both segments manufacture and market comprehensive lines of residential gas, gas tankless and electric water heaters and commercial water heating equipment. Both segments primarily serve their respective regions of the world. The North America segment also manufactures and markets specialty commercial water heating equipment, condensing and non-condensing boilers and water system tanks. The Rest of World segment also manufactures and markets water treatment products, primarily in Asia.

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, was used to measure the performance of the segments.

- Definition

Assets, usually stocks, bonds, and other investments, that have been segregated and restricted (usually in a trust) to provide benefits, at their fair value as of the measurement date. Plan assets include amounts contributed by the employer (and by employees for a contributory plan) and amounts earned from investing the contributions, less benefits paid. If a plan has liabilities other than for benefits, those non-benefit obligations may be considered as reductions of plan assets.
