These two bits of guidance came to mind when reading about MF Global over the past few weeks, regarding its Chief Risk Officer, the financial services equivalent of a CCO. As reported on December 15, in a New York Times (NYT) article entitled “MF Global’s Risk Officer Said to Lack Authority” Ben Protess and Azam Ahmed reported that the company replaced its Chief Risk Officer, Michael Roseman, earlier in 2011, after he “repeatedly clashed with Mr. Corzine [the CEO] over the firm’s purchase of European sovereign debt.” He was given a large severance package and left the company. When he left, there was no public reason given. His replacement was brought into the position with reduced authority.
