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

                             A. O. SMITH CORPORATION
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                               September 30, 1999
                                   (unaudited)

1.   Basis of Presentation

     The 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 and nine-month  periods
     ended  September  30, 1999 are not  necessarily  indicative  of the results
     expected for the full year. The  consolidated  balance sheet as of December
     31, 1998 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 1999 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, the Company  acquired the assets of the motors  business
     of  MagneTek,  Inc.  for $253  million,  subject to final  adjustment.  The
     company  funded  the  acquisition  through  available  cash ($42  million),
     proceeds  from  the  issuance  of  commercial   paper  ($103  million)  and
     borrowings  under a revolving credit facility and available lines of credit
     ($108 million).  The acquisition was accounted for by the Company using the
     purchase method of accounting and,  accordingly,  the financial  statements
     include the operating results of the acquired business from the date of its
     acquisition.

     The pro forma  unaudited  results of operations for the nine-month  periods
     ended September 30, 1999 and September 30, 1998,  assuming  consummation of
     the purchase as of January 1, 1998, are as follows:

5.   Long-Term Debt

     To  support  the  acquisition  of the  assets  of  MagneTek,  Inc.'s  motor
     business,  the  company  entered  into a  $350  million  multi-year  credit
     facility on August 2, 1999, with nine different banks. The facility is made
     up of two  tranches:  $100 million  which  expires July 28, 2000,  and $250
     million which expires  August 2, 2004.  The previous $100 million  facility
     expiring on June 30, 2001 was terminated on August 2, 1999.

     The company's  long-term credit agreements  contain certain  conditions and
     provisions,  which restrict the company's  payment of dividends.  Under the
     most restrictive of these  provisions,  retained  earnings of $59.7 million
     were  unrestricted as of September 30, 1999 for cash dividends and treasury
     stock purchases.

6.   Comprehensive Earnings (Loss)
     The company's  comprehensive  earnings were $12.6 million and $36.9 million
     for the three- and  nine-month  periods ended  September 30, 1999 and $11.4
     million  and  $33.8  million  for the three and  nine-month  periods  ended
     September 30, 1998. Comprehensive earnings, for all periods presented, were
     comprised of net earnings and foreign currency translation adjustments.  No
     provisions  or  benefits  for U.S.  income  taxes  have  been made on these
     foreign currency translation adjustments.

7.   Earnings per Share of Common Stock
     The numerator for the  calculation of basic and diluted  earnings per share
     is net earnings.  The following  table sets forth the  computation of basic
     and  diluted  weighted-average  shares  used  in  the  earnings  per  share
     calculations:

     Intersegment  sales, which are immaterial,  have been excluded from segment
     revenues.

     The assets of the Electric  Motor  Technologies  segment  increased by more
     than $315 million at September 30, 1999  compared with the amount  reported
     in the  December  31,  1998 annual  report.  This  increase  was due to the
     aforementioned  MagneTek motor business  acquisition on August 2, 1999 (see
     note 3).

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

RESULTS OF OPERATIONS
- ---------------------
FIRST NINE MONTHS OF 1999 COMPARED WITH 1998
- --------------------------------------------

Sales increased 31% to $318.3 million in the third quarter of 1999 compared with
1998  third  quarter  sales of $243.3  million.  Significantly  higher  sales at
Electric  Motor  Technologies  benefiting  from the  recent  acquisition  of the
MagneTek motor business,  and a 6% increase at Water Systems  Technologies  more
than offset a 15% decline in sales in the Storage & Fluid Handling  Technologies
segment.  Sales for the first  nine  months of 1999 were  $838.4  million or 21%
higher than the $692.9  million of sales  generated  during the same period last
year.  Of  the  $145.5  million  increase  in  sales,  acquisitions  contributed
approximately $132.0 million,  while the inclusion of the sales of the company's
wholly-owned  Chinese entities accounted for $9 million.  In 1998, the company's
Chinese operations were reported as equity in income and were not consolidated.

Third quarter net earnings  increased  12.7% to $12.4 million  compared with $11
million  earned in the third  quarter of 1998.  Significantly  higher  operating
profit at Electric  Motors more than offset the decline in  operating  profit at
Storage & Fluid  Handling.  Net  earnings for the first nine months of 1999 were
$37.7  million  compared  with $33.8  million for the first nine months of 1998.
Third quarter  diluted  earnings per share increased from $0.46 in 1998 to $0.52
in 1999. Diluted earnings per share for the first nine months of 1999 were $1.59
compared with $1.39 in the same period last year.

The third quarter gross profit margin  declined to 18.8% from 19.3% in the third
quarter of 1998 as a result of the  decline in  profitability  in the  Storage &
Fluid Handling business, and the inclusion of the MagneTek motor business, which
carries a lower gross margin relative to the consolidated gross profit margin of
the  company's  other  businesses.  The gross  profit  margin for the first nine
months declined to 19.6% in 1999 from 20.3% in 1998 consistent with  acquisition
activity and decreased profitability at Storage & Fluid Handling.

Third  quarter  sales of $211.6  million for the  Electric  Motors  Technologies
platform  were more than 56% higher than sales in the third  quarter of 1998 and
included  approximately $66 million of sales associated with the  aforementioned
acquisition of the MagneTek motor business. The balance of the increase in sales
was due to  higher  demand in the  heating,  ventilating,  and air  conditioning
market, increased export motor volume, and higher sales in the company's general
industries  business.  Year-to-date  sales for the electric  motor  segment were
$516.1 million in 1999 compared with $360.9 million in 1998. The 43% increase in
sales for the first nine months of 1999 reflects the  additional  sales from the
company's  MagneTek motor business  acquisition;  the acquisition of the General
Electric  compressor  motor  business  in July 1998;  and the growth in the base
business  excluding  acquisitions.


                                       9


Operating   profit  for  the  Electric  Motor   Technologies   segment  improved
significantly  in both the third  quarter and first nine months of 1999 compared
with 1998 as a result of the increased volume.

Third  quarter sales of Water  Systems  Technologies  were $75.8 million or 5.7%
higher than 1998's third  quarter sales of $71.7  million,  due primarily to the
inclusion  of sales for the  Chinese  operation.  Volumes  in both the  domestic
residential and commercial markets were flat compared with the year ago quarter.
Sales for the first  nine  months of 1999 were  $236.5  million,  compared  with
$220.5  million for the first nine months of 1998.  Water Systems  Technologies'
third  quarter  operating  profits  declined  from $7.8  million in 1998 to $7.2
million in 1999 reflecting the impact of sluggish domestic markets and continued
investment to support the growing Chinese water products  business.  Through the
first nine months of 1999,  operating profits were $24.1 million or $1.8 million
higher  than the same period  last year as a result of  increased  volume in the
first half of 1999.

Third quarter and  nine-month  sales in the Storage and Fluid  Handling  segment
declined 14.8% and 23.1%, respectively,  compared with the same periods in 1998.
The steepest decline occurred in the fiberglass pipe operation, as sales to both
petroleum  marketing and chemical  markets were  significantly  lower throughout
1999 compared with 1998. The decline in the petroleum  marketing segment was due
mostly to the  expiration of certain EPA  regulations  whereas  chemical-related
markets continue to suffer from weak capital spending.  Reduced capital spending
in the chemical and food processing  business  adversely affected demand for the
segment's storage tank products.

As a result of the lower volume,  third quarter operating profits of the Storage
and  Fiberglass  Products  segment  declined  from $1.5  million in 1998 to $0.9
million in 1999. On a year-to-date  basis,  profits dropped from $7.3 million in
1998 to $1.1 million in 1999.

Third quarter selling, general and administrative (SG&A) expenses increased $9.3
million  compared with the same quarter in 1998. As a percentage of sales,  SG&A
increased  to 11.2%  compared  with 10.8% in the third  quarter  of 1998.  These
increases  resulted  from  the  MagneTek  motor  business  acquisition  and  the
inclusion of the Chinese entities,  which were not consolidated in 1998. Through
the first nine months of 1999,  SG&A was 11.0% of sales  compared  with 11.6% in
1998. The year-to-date  decline in SG&A relative to sales reflects the impact of
the operating  expense  leverage  resulting from the  acquisition of the General
Electric compressor motor business at mid year 1998.

Net  interest  expense  for the  third  quarter  and first  nine  months of 1999
exceeded  that of the  comparable  periods  by $2.2  million  and $5.9  million,
respectively.  The increased  financing cost was associated with the acquisition
of the  General  Electric  compressor  motor  business  in  July  1998,  and the
acquisition of the MagneTek motor business in August 1999.


                                       10


Other  expense  for the third  quarter  and first  nine  months of 1999  doubled
compared with the same periods in 1998 primarily as a result of higher  goodwill
amortization costs related to the previously discussed acquisitions.

The  effective  tax rate for the third  quarter of 1999 was 32.6%  compared with
35.2% in the third  quarter of 1998.  1999  benefited  from  recognition  of tax
credits associated with the resolution of the company's Research and Development
tax credit claim. The company's  effective tax rate for the first nine months of
1999 and 1998 was approximately 35%.

During the first nine months of 1999 and 1998,  the company was party to futures
contracts  for the  purposes  of  hedging  a portion  of  certain  raw  material
purchases.  The company was also a party to forward exchange  contracts to hedge
foreign currency transactions consistent with its committed exposures. Had these
contracts  not been in place,  the  earnings of the company  would not have been
materially affected.


Liquidity & Capital Resources
- -----------------------------

The company's  working capital was $213.0 million at September 30, 1999 compared
with $155.2  million at December 31,  1998,  an increase of $57.8  million.  The
majority of the increase in working  capital was a result of the MagneTek  motor
business  acquisition.  Cash flow from  operations  for the year to date  period
ended  September  30, 1999,  excluding  acquisitions,  declined to $22.7 million
compared with $25.0 million for the same period last year, as a result of higher
capital spending.

Capital  expenditures  during the first nine  months of 1999 were $26.6  million
compared with $20.1  million  through  September  30, 1998.  The majority of the
capital  spending  increase was related to higher  spending  requirements in the
motor business. The company projects total capital spending in 1999 to be higher
than 1998, but expects such capital expenditures to be covered by cash flow from
operations.

The company's  long-term debt increased  $213.2 million in the first nine months
of 1999.  The increase  was a result of the  aforementioned  acquisition  of the
MagneTek motor business on August 2, 1999. Additionally,  the company's leverage
as measured by the ratio of total debt to total  capitalization was 45% compared
with 25% at December 31, 1998.

Under the  company's  odd lot  repurchase  program  initiated in July 1999,  the
company purchased 1,914 shares of its common stock during the third quarter.

At its October 13, 1999  meeting,  A. O. Smith's  Board of Directors  declared a
regular quarterly cash dividend of $.12 per share on its common stock (Classes A
and Common).  The dividend is payable on November  15, 1999 to  shareholders  of
record on October 29, 1999.


                                       11


Year 2000
- ---------
The  company has  organized  its  activities  to prepare for the Year 2000 (Y2K)
under  a   company-wide   project  that   involves   four  phases:   assessment,
modification, testing, and implementation.

The Y2K readiness project is a company-wide  effort and is monitored  centrally.
Each business segment has a core of full-time individuals who have been assigned
specific Y2K responsibilities in addition to their regular assignments.

The assessment and modification phases are complete. Key customers,  vendors and
service  providers  have  been  queried  about  their Y2K  readiness,  and their
responses  have been analyzed.  All critical  suppliers have responded that they
are Y2K compliant.

The testing and implementation phases for renovated Information  Technology (IT)
systems are nearing  completion.  All critical IT systems  that were  previously
determined  to  have  potential  Y2K-related  problems  have  been  replaced  by
Y2K-certified systems or renovated and tested for Y2K readiness.  Completion and
testing of remaining non-critical modules of renovated systems will be completed
during the remainder of the year.

Costs  specifically  associated with  renovating  software for Y2K readiness are
funded through  operating cash flow and expensed as incurred.  Y2K-related costs
have not had a material effect on the company's financial position or results of
operations.  The  company  expects to incur total  costs of  approximately  $2.0
million on the Y2K problem of which the remaining costs are  approximately  $125
thousand.

To prepare for  unforeseen  Y2K problems,  each  business  segment has developed
formal contingency plans which include ensuring availability of in-house support
and technical  personnel  during the  transition  to the new year,  establishing
earlier reporting  deadlines,  and completing  certain critical processes before
year-end.

Following the company's recent  acquisition of the worldwide motor operations of
MagneTek,  Inc.  MagneTek has continued to provide data processing  services for
those  operations.  MagneTek  has  completed  the review  and  testing of its IT
systems to  eliminate  Y2K problems and final  implementation  is  substantially
complete.

The company  believes that all critical IT and non-IT systems and processes will
be Y2K compliant  and allow the company to continue  operations in the Year 2000
and beyond  with no  material  impact on its  financial  position  or results of
operations.  Unanticipated  problems  including,  but not limited  to,  critical
suppliers and business  partners not meeting their  commitments to be Y2K ready,
and the loss of critical  skilled  personnel,  could  result in an  undetermined
financial risk.


                                       12


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, 1998, 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 futures
contracts  to minimize  such  exposures  for periods of less than one year.  The
company does not engage in speculation in its derivatives strategies. There have
been no material changes in the company's  futures  contracts since December 31,
1998.

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",  "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 its financial goals 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.  Among  such
numerous  factors,  the company  includes the continued growth of the world-wide
air conditioning,  heating, and refrigeration market; the weather and its impact
on the HVAC, pool and spa pump markets; and the timely and proper implementation
of  future  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
- --------------------------

Dip Tube Litigation
- -------------------

The  Company  previously  reported on the Dip Tube  Litigation  in its Form 10-Q
Report for the Quarter  ended  March 31,  1999.  Subsequent  to the close of the
third  quarter the  company  entered  into a  settlement  of a lawsuit  which is
pending in the United States District Court,  Western District of Missouri.  The
lawsuit  was  brought by  individuals  on behalf of  themselves  and all persons
throughout  the United  States who have owned or  currently  own a water  heater
manufactured by Rheem Manufacturing  Company, A. O. Smith Corporation,  Bradford
White Company,  American Water Heater Company,  Lochinvar  Corporation and State
Industries,  Inc.  (the "Water  Heater  Manufacturers")  that contain a dip tube
manufactured,  designed,  supplied  or sold by  Perfection  Corporation  between
August, 1993 and October, 1996.

The class claims in the lawsuit are broad and  comprehensive  and include by way
of example  claims for breach or  violation of federal,  state,  common or other
laws;  breach of any duties  imposed by contract or  otherwise;  claims based on
strict product  liability,  negligence,  breach of express or implied  warranty,
fraud,  conspiracy,  suppression,  consumer  fraud,  unfair or  deceptive  trade
practices,  negligent or intentional misrepresentation or the Magnuson-Moss Act,
etc. The plaintiffs  and  defendants  have reached a settlement of the claims of
this litigation.  On October 21, 1999 the parties  petitioned the court to enter
an order  determining that the suit may be maintained as a class action and that
the class be constituted  as set forth in the complaint.  The petition also asks
for preliminary approval of the proposed settlement and approval of the form and
manner of notice  which will be given to the class  members.  The court has also
been asked to set a date for a hearing on the  fairness  of the  settlement  and
final  approval  of the  settlement.  To date,  the court has not acted upon the
petition of the parties.

The settlement  agreement  anticipates a procedure  whereby members of the class
will be able to file claims for reimbursement of damages previously incurred for
the repair or  replacement of a subject dip tube and for those class members who
have not  incurred  out-of-pocket  expense  or whose  subject  dip tube  related
problems have not been fully remedied,  the settlement  provides a procedure for
the repair and  replacement  of the subject dip tubes at no expense to the class
member.  The  expenses  of the  reimbursements,  repairs  and  replacements  and
administration  of the  settlement  will be paid by the  defendant  Water Heater
Manufacturers. The settlement agreement contemplates an application to the court
for an award of  reasonable  attorney's  fees and  reimbursement  of  litigation
expenses  incurred  on behalf of class  members by counsel  for the class in the
amount  of  $5,650,000.  The  court  approved  award  would  also be paid by the
defendant Water Heater  Manufacturers.  In consideration of the agreement by the
Water Heater  Manufacturers to effectuate the terms of the settlement  agreement
for the  benefit  of the class  members,  the class  members  will  release  and
discharge the Water Heater  Manufacturers from any liability for settled claims.
Further,  all such  claims  of the class  against  Perfection  Corporation,  the
manufacturer of the subject dip


                                       14


tubes,  will be deemed assigned to the Water Heater  Manufacturers.  Individuals
can elect to be excluded from the class and separately pursue their remedies and
if so elected would not be entitled to the benefits of the settlement agreement.
The parties are requesting the court to stay all other legal actions  brought or
to be brought  against  the Water  Heater  Manufacturers  until this  lawsuit is
resolved.

Separately,  the Water Heater Manufacturers on September 29, 1999 filed a direct
action lawsuit in the Civil  District Court for the Parish of Orleans,  State of
Louisiana  against the insurers of  Perfection  Corporation  and American  Meter
Company, the parent company of Perfection.  This lawsuit seeks coverage from the
defendant  insurance  companies  for (i)  the  damages  that  the  Water  Heater
Manufacturers  and the class  members in the federal  court  action  referred to
above have  incurred  because  of the  property  damages  caused by the dip tube
failures,  (ii) the  liability  of the Water  Heater  Manufacturers  assumed  by
Perfection by contract,  and (iii) the personal  injuries  suffered by the Water
Heater Manufacturers as a result of the disparagement of them and their products
in the media reports relating to the dip tubes.

As of this date,  it is  premature  for the company to determine  what,  if any,
costs it will incur with  respect to the  aforementioned  settlement.  It is the
Company's  expectation  that all or a  substantial  portion of the costs will be
recovered from the insurers of Perfection Corporation and American Meter Company
