Sub-Prime Meltdown

To date, more than $170 billion has evaporated from the balance sheets of companies around the world as the result of the meltdown of the U.S. subprime mortgage market. Commercial banks and investment banks have been the hardest hit, with write-downs by Citigroup and UBS alone accounting for more than $28 billion. Losses have been nearly evenly split between U.S. and non-U.S. companies.
