Washington Mutual CEO Alan Fishman.
When WaMu failed and was seized by government regulators, Fishman had been on the job for just 17 days. However, he was contractually guaranteed $11.6 million in cash severance on top of the $7.5 million signing bonus he got for taking the job.
Basically, Fishman netted just under $20 million for 17 days of work, which is a pretty nice setup for the head of a collapsing corporation.
