  claim: Owens Corning announced a impairment with charges of approximately $140 million affecting global glass reinforcements business.
  evidence_excerpt: On February 14, 2025, Owens Corning (the “Company”) disclosed an expected impairment charge associated with the announced sale of the Company’s global glass reinforcements business (the “GR Business”) and that, beginning with the Quarterly Report on Form 10-Q for the period ended March 31, 2025, the GR Business’s financial results would be reflected in the Company’s consolidated financial statements as discontinued operations for all periods presented, and the GR Business would be classified as “held for sale." Based on the revised terms of the Transaction (as described below), the Company will recognize an additional loss on sale of approximately $140 million related to a decrease in the agreed purchase price and changes in other net assets, subject to finalized cumulative foreign currency adjustments, net working capital adjustments, and costs to sell.
