Fortune 500 rank: 14
2010 revenue: $111.1 billion
10-year annualized return: -18.3%
Maybe it should be rebranded, "Too Big To Succeed." Sandy Weill's financial supermarket nearly fell victim to a portfolio stuffed with junky mortgages during the credit crisis before being saved by a $45 billion government bailout.
After Weill left in 2003, CEO Chuck Prince never managed to fully coordinate the bank's disparate operations in 100 countries. This failure led to mismanagement and eventually Citi's near-collapse.
A redemption story may be in the works, however: in 2010, Citi posted its first annual profit since the crisis.
NEXT: 8. Eastman Kodak
