Owens Corning entered an amendment to the sale agreement for its global glass reinforcements (GR) business. The enterprise value for the sale has been reduced from $755 million to $645 million. The company will recognize an additional $140 million impairment charge due to the price reduction and asset adjustments. The amendment includes the transfer of $65 million in additional assets and the elimination of promissory notes. The company received a $30 million non-refundable deposit upon signing the amendment. Expected after-tax net proceeds from the transaction are approximately $280 million.
