ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.

On August 15, 2003, Ampco-Pittsburgh Corporation (the Corporation) sold the stock of its New Castle Industries (NCII) group of companies which constituted its small Plastics Processing Machinery segment to Xaloy Inc., a subsidiary of Saurer Ltd., Switzerland. The pending transaction was disclosed in the Corporation’s Form 10-Q dated August 14, 2003.

The proceeds, subject to post-closing adjustments, approximated $16.85 million resulting in a loss on the sale of approximately $2.75 million which will be recognized in the third quarter. Of the purchase price, $14.6 million was paid at closing, $1 million is payable no later than October 15, 2003, and the balance is in the form of a 3-year promissory note guaranteed by Saurer Ltd. The note bears interest at the prime rate and is payable quarterly.

The Plastics Processing Machinery segment manufactured and sold, through NCII, feed screws, barrels, chill rolls and heat transfer rolls principally to the plastics processing and plastics machinery industries. Sales approximated $24.6 million and operating results were a loss of approximately $1.2 million for 2002.

The sale of the NCII group of companies will be accounted for as a discontinued operation. In addition to the loss on sale, the Corporation will incur environmental remediation costs for two of NCII’s Pennsylvanian facilities. An estimate for costs to clean up is expected to be available before third quarter results are announced.

Consideration for the stock of NCII was determined by arm’s length negotiations among parties to the transaction. There is no relationship between the Corporation and Xaloy, Inc. or Saurer, Ltd. including with any directors or officers.
