Eqecat Inc. - a catastrophe modeling and risk consulting firm - said on its website that as of Oct. 29 it has issued estimates of between $5 billion and $10 billion of insured losses from Hurricane Sandy. If insured losses come in on the high end of their estimate, that would make Hurricane Sandy the fifth-costliest in U.S. history behind Hurricane Wilma, which caused $11.7 billion of insured losses in Florida in 2005.
