PART I - FINANCIAL INFORMATION
ITEM 1 - FINANCIAL STATEMENTS

                             A. O. SMITH CORPORATION
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                               September 30, 2002
                                   (unaudited)
1.    Basis of Presentation
      The accompanying unaudited condensed consolidated financial statements
      have been prepared in accordance with accounting principles generally
      accepted in the United States for interim financial information and
      pursuant to the rules and regulations of the Securities and Exchange
      Commission. Accordingly, they do not include all of the information and
      footnotes required for complete financial statements. In the opinion of
      management, all adjustments (consisting of normal recurring accruals)
      considered necessary for a fair presentation have been included. Operating
      results for the three- and nine-month periods ended September 30, 2002 are
      not necessarily indicative of the results expected for the full year. It
      is suggested that the accompanying condensed consolidated financial
      statements be read in conjunction with the audited consolidated financial
      statements and the notes thereto included in the company's latest Annual
      Report on Form 10-K. Certain prior year amounts have been reclassified to
      conform to the 2002 presentation.

2.    Acquisitions
      On July 1, 2002, A. O. Smith Corporation (the company) completed the
      purchase of the hermetic motor assets of the Athens Products (Athens)
      division of Electrolux Group for cash consideration of $9.6 million. The
      purchase price was allocated to the assets acquired and liabilities
      assumed based upon current estimates of their respective fair values at
      the date of acquisition.

      On December 28, 2001, the company acquired all of the outstanding stock of
      State Industries, Inc. (State) for an aggregate purchase price of $117.6
      million. This was comprised of $57.8 million for the outstanding stock,
      assumption of $56.3 million of debt, and $3.5 million of acquisition
      costs, of which $2.2 million were paid during the nine-month period ended
      September 30, 2002. The purchase price was allocated to the assets
      acquired and liabilities assumed based upon current estimates of their
      respective fair values at the date of acquisition.

      In connection with our acquisition of Athens in July 2002, we recorded
      additional purchase liabilities of approximately $4.2 million primarily
      for employee severance costs associated with product manufacturing
      repositioning. As of September 30, 2002, we have charged $0.7 million
      against this reserve.

      In connection with the Athens acquisition and certain other acquisitions
      by the company, aggregate additional purchase liabilities of $26.0 million
      were recorded at the respective acquisition dates for employee severance
      and relocation, as well as certain facility exit costs. As of September
      30, 2002, costs incurred and charged against these liabilities to date
      totaled $15.4 million.

                                       6


3.    Business Improvement Programs
      In the fourth quarter of 2001, the company recorded restructuring and
      other charges of $9.4 million. The charges included employee separation
      costs of $7.7 million associated with product or component manufacturing
      repositioning and the realignment of certain administrative functions. The
      resulting reduction of workforce is approximately 150 salaried and 775
      hourly employees. In addition, the company recorded facility impairment
      and lease charges of $1.7 million representing estimated costs of
      facilities to be vacated. The company spent $2.9 million through September
      30, 2002. At September 30, 2002, the company estimates approximately 520
      employees are yet to be impacted and plans to be substantially completed
      with the realignment activities prior to June 30, 2003.

5.    Goodwill and Other Intangible Assets
      The company adopted Statement of Financial Accounting Standards (SFAS) No.
      142, "Goodwill and Other Intangible Assets", effective January 1, 2002.
      Under SFAS No. 142, goodwill and certain other intangible assets are no
      longer amortized but are reviewed for impairment. In connection with the
      adoption of SFAS No. 142, the company has completed the first step of the
      transitional goodwill impairment test, which requires the company to
      compare the fair value of its reporting units to the carrying value of the
      net assets of the respective reporting units as of January 1, 2002. Based
      on this analysis, the company has concluded that no impairment existed at
      the time of adoption, and, accordingly, the company has not recognized any
      transitional impairment loss.

      Changes in the carrying amount of goodwill during the nine-month period
      ended September 30, 2002 consist of the following (000 omitted):

6.    Long-Term Debt
      The company's credit agreement and term notes contain certain conditions
      and provisions which restrict the company's payment of dividends. Under
      the most restrictive of these provisions, retained earnings of $200.6
      million were unrestricted as of September 30, 2002.

7.    Common Stock Issuance
      On May 10, 2002, the company completed the sale of 4,776,065 shares of its
      common stock held in treasury. The $127.5 million net proceeds from the
      offering were used to reduce long-term debt.

8.    Comprehensive Earnings (000 omitted)
      The company's comprehensive earnings are comprised of net earnings,
      foreign currency translation adjustments, and realized and unrealized
      gains and losses on cash flow derivative instruments. Also included in
      comprehensive earnings for the nine-month period ended September 30, 2001
      was a cumulative loss adjustment on cash flow hedges of approximately $0.6
      million in connection with the adoption of Statement of Financial
      Accounting Standards (SFAS) No. 133, "Accounting for Derivative
      Instruments and Hedging Activities", as amended, on January 1, 2001.

11.   Accounting for Derivative Instruments
      The company utilizes certain derivative instruments to enhance its ability
      to manage currency exposures and raw materials price risks. Derivative
      instruments are entered into for periods consistent with the related
      underlying exposures and do not constitute positions independent of those
      exposures. The company does not enter into contracts for speculative
      purposes. The company has hedged certain of its forecasted exposures.
      Approximately 89 percent of these contracts expire by December 31, 2003.
      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 and certain inter-company transactions in the normal course of
      business. Contracts typically have maturities of a year or less. Principal
      currencies include the Mexican peso, Hungarian forint, British pound, Euro
      and U.S. dollar.

      Forward contracts are accounted for as cash flow hedges of a forecasted
      transaction. The fair value of these currency derivatives of $4.9 million
      has been recorded in accrued liabilities as of September 30, 2002. A fair
      value of $6.6 million for currency derivatives has been recorded in other
      current assets as of December 31, 2001. Gains and losses on these
      instruments are initially recorded in other comprehensive income (loss)
      and subsequently reclassified into earnings when the underlying
      transaction affects income. The assessment of effectiveness for forward
      contracts is based on changes in the forward rates. These hedges have been
      determined to be perfectly effective.

      Commodity Future Contracts
      In addition to entering into supply arrangements in the normal course of
      business, the company also enters into future contracts to fix the cost of
      certain raw material purchases, principally copper and aluminum, with the
      objective of minimizing changes in inventory cost due to market price
      fluctuations.

      The commodity future contracts are designated as cash flow hedges of a
      forecasted transaction. Derivative commodity liabilities for copper of
      $3.6 million and $6.2 million are recorded in other current liabilities as
      of September 30, 2002 and December 31, 2001, respectively. Derivative
      commodity liabilities for aluminum of $0.3 million and $0.7 million are
      recorded in accrued liabilities as of September 30, 2002 and December 31,
      2001, respectively. Overall, the value of the effective portions of the
      commodity contracts of ($3.3) million and ($6.9) million are recorded in
      accumulated other comprehensive income (loss) as of September 30, 2002 and
      December 31, 2001, respectively, and subsequently 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 into earnings in the period in which the ineffectiveness occurs.
      Hedge ineffectiveness and impact on earnings was not material for the
      three- and nine-month periods ended September 30, 2002 and 2001,
      respectively.


                                       10


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

$895.6 million in the same period last year. The increase in third quarter sales
was due to our acquisitions of State Industries Inc. (State) in December 2001
and Athens Products (Athens) in July 2002 as well as higher sales in the base
water heater business. The increase in year-to-date sales was due to the
acquisitions partially offset by lower sales of electric motors in the first
half of the year.

Our gross profit margin for the third quarter of 2002 increased from 15.8
percent in 2001 to 18.8 percent. Our year-to-date gross profit margin in 2002
was 20.2 percent compared with 17.9 percent in the same period in 2001. The
improved margins in both the third quarter and first nine months of 2002
resulted from product repositioning at Electrical Products, the addition of
State Industries, and material cost savings at both businesses.

Our selling, general and administrative (SG&A) expenses in the third quarter and
first nine months of 2002 were higher than the same periods in 2001 by $13.0
million and $41.9 million, respectively, primarily as a result of the
incremental SG&A associated with our State acquisition. On a year-to-date basis
SG&A was 13.7 percent of sales compared with 12.3 percent of sales for the first
nine months of 2001. The increase in SG&A relative to sales resulted from our
Water Systems business which has higher SG&A levels and has grown from 29.2
percent of our total company sales in the first nine months of 2001 to 44.8
percent of total company sales in the same period of 2002.

Interest expense for the third quarter and first nine months of 2002 was lower
than the comparable periods in 2001 by $1.0 million and $1.8 million,
respectively, due to lower interest rates and reduced debt levels resulting from
our stock offering (see Note 7 of Notes to Condensed Consolidated Financial
Statements).

We have significant pension benefit costs and credits that are developed from
actuarial valuation. The valuations reflect key assumptions regarding, among
other things, discount rates, expected return on plan assets, retirement ages,
and years of service. Consideration is given to current market conditions,
including changes in interest rates, in making these assumptions. During the
second quarter of 2002, we reduced our assumption for expected rate of return on
plan assets from 10.0 percent to 9.75 percent. The amount of pension credit
recognized in the third quarter and first nine months of 2002 was $4.1 million
and $12.7 million, respectively, and compared with $5.0 million and $15.1
million in the comparable periods of 2001. The third quarter and first nine
months of 2002 included $.5 million and $1.7 million for pension expense
associated

                                       12

with our State acquisition. The pension credits are reflected as offsets to cost
of products sold and SG&A.

Our year-to-date effective tax rate was 34.5 percent compared with 35.5 percent
for the first nine months of 2001. The effective rate in 2002 benefited from the
implementation of a more efficient tax structure for international operations
which was initially implemented in the second quarter of 2001 with additional
favorable impacts being recognized commencing with the third quarter of 2002.

Net earnings for the third quarter improved significantly to $10.0 million from
$.4 million in last year's third quarter. Net earnings of $40.1 million for the
first nine months of 2002 were more than double the net earnings of $19.6
million recognized in the same period of 2001. The increase in earnings was
attributable to lower manufacturing costs and the elimination of goodwill
amortization at Electrical Products; synergies from our State acquisition; and
higher sales volume in our base Water Systems business. On a diluted per share
basis, third quarter earnings increased from $.02 in 2001 to $.34 in 2002, while
for the first nine months per share earnings increased from $.82 in 2001 to
$1.49 in 2002. The 2002 third quarter and year-to-date earnings per share
amounts were diluted by approximately $.04 and $.11, respectively, as a result
of increased shares outstanding associated with our stock offering.

Electrical Products
Third quarter sales for our Electrical Products segment were $197.5 million or
$10.9 million higher than the same period last year with the increase
attributable to the Athens acquisition at the beginning of the quarter. Sales to
the domestic heating, ventilation and air conditioning (HVAC) market were 8
percent lower than in the third quarter of 2001 while sales of motors for pumps,
after-market and general industry applications improved more than 10 percent
compared with the same period last year. Year-to-date sales for this segment
were $612.9 million, a decline of $21.5 million from 2001 nine month sales of
$634.4 million. The year-to-date decline occurred mostly in sales to the
commercial air conditioning market.

Third quarter operating earnings for our Electrical Products segment increased
from $3.3 million (as adjusted to exclude $1.7 million of goodwill amortization)
to $10.3 million in 2002. Earnings for the first nine months were $46.0 million
or $10.0 million higher than 2001 nine month earnings of $35.9 million (as
adjusted to exclude $4.9 million of goodwill amortization). The favorable trend
in earnings reflects the impact of product repositioning and other cost
reduction programs.

Water Systems
Third quarter and nine month sales for our Water Systems segment increased by
$72.3 million and $236.5 million, respectively over the comparable periods in
2001. Sales in 2002 associated with our State acquisition were $68.9 million for
the second quarter and $230.9 million for the first nine months, accounting for
most of the year over year increase. The remaining increase in sales was
attributable to modestly higher volume for the base residential and commercial
business and the China operation.

Operating earnings for Water Systems were $13.4 million in the third quarter of
2002 reflecting a $4.6 million increase over the same period last year. For the
first nine months of 2002, earnings were $43.6 million as compared to $28.6
million for the same period last year. The improved earnings performance in the
third quarter and first nine months of 2002 compared with the same

                                       13


periods in 2001 was the result of State Industries and the synergies associated
with this acquisition and improved profitability in our China operation.

Critical Accounting Policies
Our accounting policies are described in Note 1 of Notes to Consolidated
Financial Statements as disclosed in the Form 10-K for the fiscal year ended
December 31, 2001. Also as disclosed in Note 1, the preparation of financial
statements in conformity with accounting principles generally accepted in the
United States requires the use of estimates and assumptions about future events
that affect the amounts reported in the financial statements and accompanying
notes. Future events and their effects cannot be determined with absolute
certainty. Therefore, the determination of estimates requires the exercise of
judgment. Actual results inevitably will differ from those estimates, and such
differences may be material to the financial statements.

The most significant accounting estimates inherent in the preparation of our
financial statements include estimates associated with the evaluation of the
recoverability of certain assets including goodwill and receivables resulting
from the payment of claims associated with the dip tube class action lawsuit
(see Note 13 of notes to consolidated financial statements in the Form 10-K for
the fiscal year ended December 31, 2001) as well as those estimates used in the
determination of liabilities related to warranty activity, litigation, product
liability, environmental matters and pensions and other post-retirement
benefits. Various assumptions and other factors underlie the determination of
these significant estimates. The process of determining significant estimates is
fact-specific and takes into account factors such as historical experience and
trends, and in some cases, actuarial techniques. We constantly reevaluate these
significant factors and adjustments are made when facts and circumstances
dictate. Historically, actual results have not significantly deviated from those
determined using the estimates described above.

Recent Accounting Pronouncements
The Financial Accounting Standards Board (FASB) has issued Statement of
Financial Accounting Standards (SFAS) No. 143, "Accounting for Asset Retirement
Obligations", SFAS No. 144, "Accounting for the Impairment or Disposal of
Long-Lived Assets," and SFAS No. 146, "Accounting for Costs Associated with Exit
or Disposal Activities." SFAS No. 143 will become effective for us on January 1,
2003. Adoption of this statement is not expected to have a material impact on
our consolidated financial statements. SFAS No. 144, which was adopted on
January 1, 2002, has not had a material impact on our consolidated financial
statements since its adoption. SFAS No. 146 will be effective for exit or
disposal activities initiated after December 31, 2002. Management is currently
assessing the provisions of SFAS No. 146 but believes there will be no effect on
the company's financial position or results of operations at the time of
adoption.

Outlook
The improved margin performance of our operating units is having a positive
effect on earnings per share, and consequently, we expect 2002 earnings will
range between $1.80 and $1.85 per share.

Looking ahead, we believe the challenging market conditions we are now
experiencing will continue into 2003, particularly in our electric motor
markets. However, the ongoing impact of Electrical Products' cost-reduction
actions, combined with the continued benefits of the State integration into
Water Systems will have a positive impact on 2003 earnings. Consequently, we
estimate that next year's earnings will range between $2.05 and $2.25 per share.


                                       14

Liquidity & Capital Resources
Our working capital for continuing operations was $213.1 million at September
30, 2002, $6.7 million lower than at December 31, 2001. The most significant
factor impacting working capital was the reduction in our other current assets
account as a result of receiving an expected $12.4 million tax refund. Cash
provided by our operations during the first nine months of 2002 was $98.4
million compared with $39.3 million during the same period one year ago. We
attribute the higher cash flow provided by operations to higher earnings and
improved working capital management during the first nine months of 2002
compared with the first nine months of 2001. We project operating cash flow for
the full year to approximate current levels.

Our 2002 capital expenditures through September 30 totaled $25.8 million, which
was slightly higher than the $23.4 million spent in the same period of 2001. The
increase in capital spending is associated with our recent acquisition of State
Industries. Our company is projecting 2002 capital expenditures of approximately
$40 to $45 million, an increase over 2001 capital expenditures of $35.3 million
primarily due to the acquisition of State. We believe that our facilities and
planned capital expenditures are sufficient to provide capacity for our
operations in the near term.

With the net proceeds from our stock offering completed earlier this year,
coupled with strong operating cash flow, we reduced our total debt by $174.9
million to $232.0 million at September 30, 2002. Our leverage as measured by the
ratio of total debt to total capitalization was 27 percent, down significantly
from 47 percent at the end of 2001. We did not enter into any significant
operating leases during the first nine months of 2002. At September 30, 2002,
our company had available borrowing capacity of $247.4 million under our credit
facilities. 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.

In connection with our acquisition of Athens in July 2002, we recorded
additional purchase liabilities of approximately $4.2 million primarily for
employee severance costs associated with product manufacturing repositioning. As
of September 30, 2002, we have charged $0.7 million against this reserve. In
connection with the Athens acquisition and certain other acquisitions by the
company, aggregate additional purchase liabilities of $26.0 million were
recorded at the respective acquisition dates for employee severance and
relocation, as well as certain facility exit costs. As of September 30, 2002,
costs incurred and charged against these liabilities to date totaled $15.4
million. We expect the majority of the respective activities to be completed
within the next year.

The recent decline in the U.S. equity markets has resulted in a decrease in the
value of the assets of our pension plan. We currently estimate that the
accumulated benefit obligation of our primary defined benefit pension plan
exceeds the fair value of plan assets by approximately $40 million. If the U.S.
equity markets do not recover by the plan's measurement date in the fourth
quarter, and we choose not to fund the difference between the accumulated
benefit obligation and the fair value of plan assets, we will be required to
record a charge to stockholders' equity for that difference as well as the
elimination of the current prepaid pension asset. This direct charge to equity,
which would be approximately $100 million net of tax, would have no impact on
cash or net income. If the charge is recorded it will result in an increase to
our leverage ratio from 27 percent to approximately 31 percent.

                                       15


On October 11, 2002, our board of directors declared a quarterly dividend on our
Common Stock and Class A Common Stock of $.14 per share. The dividend is payable
on November 15, 2002 to stockholders of record on October 31, 2002.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURE OF MARKET RISK
As is more fully described in our annual report on Form 10-K for the year ended
December 31, 2001, we are exposed to various types of market risks, primarily
currency and certain commodities. We monitor our risks in these areas on a
continuous basis and generally enter into forward and futures contracts to
minimize these exposures for periods of less than one year. Our company does not
engage in speculation in our derivative strategies. It is important to note that
gains and losses from our forward and futures contract activities are offset by
changes in the underlying costs of the transactions being hedged.

ITEM 4 - CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures
Our chief executive officer and chief financial officer, after evaluating the
effectiveness of the company's disclosure controls and procedures, have
concluded that these disclosure controls and procedures were adequate and
effective to ensure that material information relating to the company and its
consolidated subsidiaries would be made known to them by others within those
entities.

Changes in internal controls
There were no significant changes in our internal controls or in other factors
that could significantly affect our disclosure controls and procedures
subsequent to the date of their evaluation, nor were there any significant
deficiencies or material weaknesses in our internal controls. As a result, no
corrective actions were required or undertaken.

Forward Looking Statements
This document contains statements that we believe are "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995. Forward-looking statements generally can be identified by the use of
words such as "may," "will,""expect," "intend," "estimate," "anticipate,"
"believe," "continue," or words of similar meaning. These forward-looking
statements are subject to risks and uncertainties that could cause actual
results to differ materially from those anticipated as of the date of this
release. Factors that could cause such a variance include the following:
instability in the company's electric motor and water products markets;
inability to timely and properly integrate the acquisition of State Industries;
the inability to implement cost-reduction programs; adverse changes in general
economic conditions; significant increases in raw material prices; competitive
pressures on the company's businesses; and the potential that assumptions on
which the company based its expectations are inaccurate or will prove to be
incorrect.

Forward-looking statements included in this document are made only as of the
date of this filing, and the company is under no obligation to update these
statements to reflect subsequent events or circumstances. All subsequent written
and oral forward-looking statements attributable to the company, or persons
