On October 31 MF Global collapsed into the eighth-largest bankruptcy in U.S. history and an estimated $1.2 billion in client funds remains unaccounted for.

According to press reports, the board allowed the company’s exposure to European sovereign debt to increase by more than four times to $6.3 billion between late 2010 and shortly before it entered bankruptcy.
