Founding of Insurance Company of North America

Background. The supplied source material does not document the 1792 founding of the Insurance Company of North America. Its sole relevant passage describes ACE's 1999 purchase, for $3.45 billion, of the global property and casualty business of Cigna Corporation, most significantly INA. That transaction is excluded from this event's scope, and no supplied passage confirms the founding date, location, founders, or the company's later identity as Chubb.

Legacy Data and Corrections. The legacy row asserts a founding date of January 1, 1792, in Philadelphia. This date is considered a placeholder as the supplied passages do not confirm the specific day or month. The location of Philadelphia is retained as the historical referent for the founding, though the passages primarily discuss the company's later operations and acquisitions rather than its 18th-century origins.
