An engineering firm has reached a settlement with lawyers who have filed hundreds of lawsuits against State Farm Insurance Cos. on behalf of policyholders whose claims were denied by the insurer after Hurricane Katrina. Under terms of the settlement, North Carolina-based Forensic Analysis and Engineering Corp., which helped State Farm adjust policyholder claims in Mississippi, would be dropped from a federal lawsuit that accuses the insurer of engaging in a "pattern of racketeering" after the storm.
