American International Group is an insurer founded in Shanghai in 1919 that grew into one of the largest financial institutions in the world before its near-collapse in 2008, when losses on credit default swaps written against mortgage securities forced the largest government rescue of a single company in American history. It has spent the years since dismantling that conglomerate, separating its life and retirement business as Corebridge and selling numerous units, and it now concentrates on commercial property and casualty insurance. Headquartered in New York, it is a considerably smaller and simpler company than the one that failed.

Swift is a Belgian cooperative founded in 1973 and owned by its member banks, and it operates the messaging network through which most cross-border payment instructions travel between financial institutions worldwide.
