Cigna Unit Gets Green Light for Restructuring: A Pennsylvania judge's ruling allows the Philadelphia-based insurer to proceed with reorganizing its U.S. property and casualty business, pending an appeal by opposing insurers and policyholders. Judge James Colins of the Commonwealth Court denied a request for a stay until an April 17 hearing on whether the case will be reviewed. Pennsylvania regulators have approved Cigna Corp.'s plan to split the business. Under the plan, one unit keeps the most profitable policies and the other winds down coverage on policies with the largest claims--those from businesses forced to clean up asbestos and tainted soil. Three Cigna rivals--American International Group Inc., Chubb Corp. and St. Paul Cos.--had filed a petition asking the court to stop Cigna from proceeding.
