The Insurance Company of North America was founded in 1792. In 1920, INA created Indemnity Insurance Company of North America. This new company was necessary when INA decided to write liability insurance, workman's compensation insurance, and accident and health insurance. Indemnity Insurance Company of North America was a member of the National Council on Compensation Insurance in 1933 when the NCCI established their occupational disease program (blog entry 3/26/09). INA merged in 1982 with Connecticut General to form CIGNA. In 1999, the ACE Group of Insurance Companies acquired the property and casualty operations of CIGNA.
INA provided insurance coverage for asbestos manufacturers such as the Pittsburgh Corning Corporation, the Armstrong Cork Corporation, H.K. Porter, the Keene Corporation, Nicolet Industries, and G.A.F Corporation. Here is a March 19, 1975 letter to INA from G.A.F. in regard to a product liability claim filed in San Francisco, California against G.A.F. The lawsuit sought compensation for injuries that resulted from the handling of asbestos, fiberglass, and insulation products and materials during the period of January 1, 1943 through 1973. A copy of the letter was sent to Robert Beaulieu at Marsh and McLennan and to INA's Robert Pelletiro. On April 21, 1977, Mr. Pelletiro attended the second meeting of the Enterprise Liability Discussion Group (blog entry 2/27/09).
