GKN Aerospace Seeks Coverage For Defense Costs Amid Pollution Exclusion Dispute

GKN Aerospace has filed a lawsuit against Chubb and Markel insurance units for refusing to cover its legal defense costs following a chemical tank scare at its California facility. The incident led to the evacuation of tens of thousands of residents and dozens of lawsuits against the company.
