Bradley C. Birkenfeld

Bradley Charles Birkenfeld is an American private banker, convicted felon, and whistleblower. During the mid- to late-2000s, he made a series of disclosures about UBS Group AG clients, in violation of Swiss banking secrecy laws, to the U.S. government alleging possible tax evasion. Known as the 2007 "Birkenfeld Disclosure", the U.S. Department of Justice (DOJ) announced it had reached a deferred prosecution agreement with UBS that resulted in a US$780 million fine and the release of previously privileged information on American tax evaders.
