ITEM 1 - FINANCIAL STATEMENTS
- -----------------------------

                             A. O. SMITH CORPORATION
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 March 31, 2001
                                   (unaudited)

1.   Basis of Presentation
     The condensed consolidated financial statements presented herein are based
     on interim figures and are subject to audit. In the opinion of management,
     all adjustments consisting of normal accruals considered necessary for a
     fair presentation of the results of operations and of financial position
     have been made. The results of operations for the three-month period ended
     March 31, 2001 are not necessarily indicative of the results expected for
     the full year. The condensed consolidated balance sheet as of December 31,
     2000 is derived from the audited financial statements but does not include
     all disclosures required by generally accepted accounting principles.
     Certain prior year amounts have been reclassified to conform to the 2001
     presentation.

2.   Statement of Cash Flows
     For purposes of the Consolidated Statement of Cash Flows, cash and cash
     equivalents include short-term investments held primarily for cash
     management purposes. These investments normally mature within three months
     from the date of acquisition.

3.   Acquisition
     On August 2, 1999, A. O. Smith Corporation (the company) acquired the
     assets of MagneTek, Inc.'s (MagneTek) domestic electric motor business and
     six wholly owned foreign subsidiaries for $244.6 million. In connection
     with the MagneTek acquisition, the company recorded additional purchase
     liabilities of $17.9 million, which included employee severance and
     relocation, as well as certain facility exit costs. Costs incurred and
     charged against the liabilities to date totaled $4.0 million. The majority
     of the activities are expected to be completed by the end of 2001.

4.   Discontinued Operations
     In the first quarter 2000, the company, with the approval of the Board of
     Directors, decided to divest its fiberglass piping and liquid and dry bulk
     storage tank businesses. These sales were completed in December 2000 and
     January 2001, respectively. Net sales of these businesses were $29.0
     million for the three-month period ended March 31, 2000.

     The operating results of the discontinued businesses have been reported
     separately as discontinued operations in the accompanying financial
     statements. Certain expenses have been allocated to the discontinued
     operations, including interest expense, which was allocated based on the
     ratio of net assets of the discontinued businesses to the total
     consolidated capital of the company.

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 $62.4 million
     were unrestricted as of March 31, 2001.


7.   Comprehensive Earnings (Loss)

     The company's comprehensive earnings were $7.0 and $13.6 million for the
     three-month periods ended March 31, 2001 and 2000, respectively.
     Comprehensive earnings were comprised of net earnings, foreign currency
     translation adjustments, and at January 1, 2001 and March 31, 2001,
     realized and unrealized gains and losses on cash flow derivative
     instruments. Also included in comprehensive earnings for the period ended
     March 31, 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. The amount recorded in
     earnings during the three month period ending March 31, 2001, associated
     with the transition adjustment as of January 1, 2001, was not material to
     the company's financial statements.

8.   Earnings per Share of Common Stock

     is net earnings. The following table sets forth the computation of basic
     and diluted weighted-average shares used in the earnings per share
     calculations:

10.  Accounting for Derivative Instruments
     Effective January 1, 2001, the company adopted (SFAS) No. 133. The standard
     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

                                       8

     are recorded in net income or comprehensive income. The cumulative effect
     of adopting SFAS No. 133 was not material to the company's consolidated
     financial statements as of January 1, 2001.

     The company utilizes certain derivative instruments to enhance its ability
     to manage currency exposures and raw materials price risks. Derivative
     instruments are entered into for periods consistent with the related
     underlying exposures and do not constitute positions independent of those
     exposures. The company does not enter into contracts for speculative
     purposes. The company has hedged certain of its forecasted exposures
     through 2002. 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 intercompany 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 and
     U.S. dollar.

     Forward contracts are accounted for as cash flow hedges of a forecasted
     transaction. The net change in the fair value of these currency derivatives
     was approximately $2.4 million as of March 31, 2001. Gains and losses on
     these instruments are recorded in other comprehensive income/loss until the
     underlying transaction is recorded in earnings. When the hedged item is
     realized, gains or losses are reclassified from accumulated other
     comprehensive income/loss to the statement of earnings on the same line
     item as the underlying transaction. The assessment of effectiveness for
     forward contracts is based on changes in the forward rates.

     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, with the objective of
     minimizing changes in inventory cost due to market price fluctuations.

     The commodity future contracts are designated as cash flow hedges.
     Derivative commodity liabilities of approximately $2.2 million are recorded
     in other liabilities as of March 31, 2001 with the value of the effective
     portion of the contracts of approximately $2.0 million recorded in
     accumulated other comprehensive income/loss and reclassified into cost of
     products sold in the period in which the underlying transaction is recorded
     in earnings. Ineffective portions of the commodity hedges are recorded into
     earnings in the period in which the ineffectiveness occurs in the same
     statement of earnings line item as the intended underlying exposure is
     recorded. Hedge ineffectiveness and impact on earnings was not material for
     the three month period ended March 31, 2001.

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

PART I - FINANCIAL INFORMATION
- ------------------------------
ITEM 2 -  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
- -----------------------------------------------------------
          CONDITION AND RESULTS OF OPERATIONS
          -----------------------------------

RESULTS OF OPERATIONS
- ---------------------
FIRST THREE MONTHS OF 2001 COMPARED TO 2000
- -------------------------------------------

Sales in the first quarter of 2001 were $318.2 million or $26.4 million lower
than sales of $344.6 million in the first quarter of 2000. The entire decline in
sales occurred in the Electric Motor Technologies segment, where most product
lines were affected by lower demand compared with the prior year.

First quarter earnings from continuing operations were $8.5 million or $5.7
million less than the $14.2 million earned in the first quarter of 2000. On a
per share basis earnings from continuing operations were $.36 and $.60 for the
first quarter of 2001 and 2000, respectively. The lower earnings were a direct
result of the decline in volume experienced by Electric Motor Technologies.

The company's gross profit margin was 18.5% in the first quarter of 2001
compared with the 21.3% margin achieved in the first quarter of 2000. While the
water heater business margins were consistent from year to year, the margins in
the electric motor business declined primarily due to under-absorption of
manufacturing cost associated with the lower volume.

First quarter sales for the Electric Motor Technologies segment were $226.3
million or approximately 10% lower than sales of $252.3 million in the same
period last year. Although volume in most of this segment's product lines
declined in the first quarter of 2001, the major decrease occurred in the
heating, ventilating and air conditioning market when compared with the first
quarter of 2000.

First quarter operating profits for Electric Motor Technologies were $14.0
million in 2001 or $12.1 million less than the first quarter of 2000. The
decline in earnings was due mostly to lower sales volume, with increased utility
costs and Mexican labor inflation also having an impact.

First quarter sales for the Water Systems Technologies segment were $92.0
million, about equal to sales in the same period last year. Lower sales of
commercial water heaters were offset by higher sales in the China market.
Operating profits of $9.9 million were higher than the $9.5 million earned in
the first quarter of 2000, primarily as a result of continued improved
performance in China.

Selling, general, and administrative (SG&A) expense for the first quarter of
2001 was $38.1 million or $4.9 million lower than the $43.0 million expense in
the first quarter of 2000. The reduction in SG&A was attributable to lower
corporate expense, cost reduction programs, and lower sales. Relative to net
sales, SG&A declined from 12.5% in the first quarter of 2000 to 12% in 2001.


                                       10

Interest expense in the first quarter of 2001 declined to $4.8 million from $5.4
million in the first quarter of 2000 as a result of reduced debt levels and
lower interest rates.

The first quarter effective tax rate of 37% in 2001 was up slightly from 36.7%
in 2000.

In the first quarter of 2000, the company recognized after-tax earnings from
discontinued operations of $.5 million associated with the storage tank
business. This entity was sold early in January 2001. A more detailed discussion
of the sale transaction can be found in the company's 2000 Annual Report on Form
10-K.

Outlook
The company recently reported it anticipates further improvement in sales and
profit in the second quarter. Second-quarter earnings are expected to be in the
range of $.45 to $.50 per share. The second quarter is traditionally the
strongest season for HVAC sales, and industry inventory levels appear to be
trending down from the higher levels attained last summer and fall.

For the full year, the company continues to anticipate 2001 earnings will exceed
the 2000 results of $1.76 per share. The company recognizes that the economy is
currently very volatile, making market and sales projections more difficult.
However, the company believes that ongoing cost reduction efforts and capacity
rationalization will continue to contribute to profitability as the year
progresses.

Liquidity & Capital Resources
The company's working capital for continuing operations was $238.0 million at
March 31, 2001, $25.0 million higher than at December 31, 2000. Sales related
increases to accounts receivable of $33.6 million were partially offset by
increases to accounts payable. Cash used by operations during the first quarter
of 2001 was $13.2 million compared to $3.7 million during the same time period
one year ago primarily due to lower earnings, as explained above.

Capital expenditures by continuing operations during the first quarter of 2001
totaled $9.5 million, down from the $11.7 million spent in the first quarter of
2000. The company expects capital spending in 2001 to be essentially the same as
2000 spending levels, and expects such capital expenditures to be covered by
operating cash flow.

In connection with the MagneTek acquisition in August 1999, additional purchase
liabilities of $17.9 million were recorded, which included employee severance
and relocation, as well as certain facility exit costs. Costs incurred and
charged against the liability to date totaled $4.0 million. The majority of the
activities are expected to be completed by the end of 2001.

The company's long-term debt decreased by $20.7 million from $316.4 million at
December 31, 2000 to $295.7 million at March 31, 2001. The proceeds received
from the divestiture of the storage tank business in the first quarter were used
to reduce debt. The company's leverage as measured by the ratio of total debt to
total capitalization improved to 40% at March 31, 2001 from 42% at the end of
last year.

At its April 5, 2001 meeting, the company's Board of Directors declared a
regular quarterly dividend at $.13 per share on its common stock (Class A and
Common). The dividend is payable on May 15, 2001 to shareholders of record on
April 30, 2001.

                                       11

ITEM 3. - QUANTITATIVE AND QUALITATIVE DISCLOSURE OF MARKET RISK
- ----------------------------------------------------------------

As is more fully described in the company's annual report on Form 10-K for the
year ended December 31, 2000, the company is exposed to various types of market
risks, primarily currency and certain commodities. The company monitors its
risks in such areas on a continuous basis and, generally enters into forward and
futures contracts to minimize such exposures for periods of less than one year.
The company does not engage in speculation in its derivatives strategies. It is
important to note that gains and losses from the company's forward and futures
contract activities are offset by changes in the underlying costs of the
transactions being hedged.

Forward Looking Statements
Certain statements in this report are "forward-looking statements." These
forward-looking statements can generally be identified as such because the
context of the statement will include words such as the company "believes,"
"anticipates," "estimates," "expects," "projects," or words of similar import.

Although the company believes that its expectations are based upon reasonable
assumptions within the bounds of its knowledge of its business, there can be no
assurance that the results expressed in forward-looking statements will be
realized. Although a significant portion of the company's sales are derived from
the replacement of previously installed product, and such sales are therefore
less volatile, numerous factors may affect actual results and cause results to
differ materially from those expressed in forward-looking statements made by, or
on behalf of, the company. The company considers most important among such
factors, the stability in its electric motor and water products markets, the
timely and proper integration of the MagneTek motors acquisition, and the
implementation of associated cost reduction programs.

All subsequent written and oral forward-looking statements attributable to the
company, or persons acting on its behalf, are expressly qualified in their
entirety by these cautionary statements.

PART II - OTHER INFORMATION

ITEM 1 - LEGAL PROCEEDINGS
- --------------------------

There have been no material changes in the legal and environmental matters
previously reported in Part 1, Item 3 and Note 12 of the Notes to Consolidated
Financial Statements in the company's Form 10-K Report for the year ended
December 31, 2000, which is incorporated herein by reference. In such report,
the company advised that the State of Colorado had given notice that it intended
to commence a legal action against the company to recover the remediation and
oversight costs it incurred at a gold mine in Colorado that was primarily
remediated by the U.S. EPA. The State filed such action against the company and
other PRPs in the first quarter. The company continues to believe it has very
good defenses to the claims of the former owner and the State of Colorado.
