Standard & Poor's removed all of the ratings from Creditwatch, where it placed them on Sept. 4 for a possible downgrade. Allstate subsidiary PMI Mortgage Insurance Co.'s AAA claims-paying ability rating remains on CreditWatch for a possible downgrade, the rating agency said. "The Allstate property/casualty group downgrade is based on the company's expected nearly $2 billion gross loss from Hurricane Andrew, which made landfall in late August," Standard & Poor's release says, "The life ratings are lowered due to the reduced financial flexibility that results from Hurricane Andrew-related losses suffered by parent Allstate." Standard & Poor's has downgraded Westinghouse Credit Corp.'s senior debt to A-minus from A, preferred stock to BBB-plus from A-minus, commercial paper to A2 from A1.
