CIGNA was formed in 1982 through the combination of INA Corporation and Connecticut General Corporation. CIGNA's formation in 1982 combined a leading property-casualty insurer with a leading supplier of life insurance and employee benefits. CIGNA has tightened its focus on employee benefits, divesting its individual life insurance business in 1998, and its domestic and international property and casualty operations in 1999.
