Item 2.   Acquisition or Disposition of Assets.

          On August 2, 1999, A. O. Smith  Corporation  (the "Company")  acquired
substantially all of the assets of the Motors and Controls Division of MagneTek,
Inc., a Delaware corporation  ("MagneTek"),  used primarily in the operations of
the business of developing,  manufacturing, selling and distributing fractional,
integral and DC electric  motors (the "Motors  Business"),  pursuant to an Asset
Purchase Agreement, dated as of June 28, 1999, among MagneTek,  MagneTek Service
(U.K.) Limited and the Company (the "Asset Purchase  Agreement").  The Company's
acquisition  of the assets of the Motors  Business  is referred to herein as the
"Acquisition."

          Pursuant to the Asset Purchase Agreement,  except for certain excluded
assets  (including  cash,  tax refunds,  certain  third party  claims,  business
information,  MagneTek's  business  name,  certain  records,  interests in joint
ventures, obligations of affiliates of MagneTek, certain agreements with respect
to  commodities,  MagneTek's  facility  in Cegled,  Hungary,  certain  logistics
facilities,  certain  intellectual  property and certain corporate assets),  the
Company  acquired the stock of six foreign  subsidiaries  of MagneTek and all of
the  business,  rights,  claims and assets of  MagneTek  used  primarily  in the
operation of the Motors Business,  including, but not limited to, (a) owned real
property, (b) leased real property, (c) personal property, (d) inventories,  (e)
intellectual  property,  (f) contracts,  (g) licenses and permits, (h) books and
records, (i) insurance proceeds, (j) accounts receivable,  (k) prepaid expenses,
(l) third party claims,  (m) certain  logistics  facilities  and (n)  intangible
rights and assets.

          As consideration  for the assets of the Motors  Business,  the Company
(i) assumed various  liabilities of MagneTek arising out of the Motors Business,
and  (ii)  paid  approximately  $250  million  in  cash  at the  closing  of the
Acquisition,  subject to adjustment.  The purchase price paid by the Company for
the assets of the Motors  Business was  determined  on the basis of arm's length
negotiations  between the parties.  The Company funded the  Acquisition  through
available cash and proceeds from the issuance of commercial paper and borrowings
under a credit facility with Bank of America,  N. A., The First National Bank of
Chicago, The Bank of New York, Citibank, N. A., Firstar Bank Milwaukee, N. A., M
& I Marshall & Ilsley Bank, Northwest Bank Wisconsin,  N. A., U.S. Bank National
Association, and Wachovia Bank, N. A.

          The Asset  Purchase  Agreement  is filed as an exhibit to this Current
Report on Form 8-K and is incorporated herein by reference. The brief summary of
the  material  provisions  of the Asset  Purchase  Agreement  set forth above is
qualified in its entirety by reference to the Asset Purchase  Agreement filed as

          MagneTek  used the assets of the Motors  Business  in the  business of
developing,  manufacturing, selling and distributing fractional, integral and DC
electric  motors.  The  Company  intends to continue to use such assets for that
purpose.
