Citigroup

This is the Citi. One of the largest financial services firms known to man, Citigroup (aka Citi) has some 200 million customer accounts and does business in more than 100 countries. Citigroup offers deposits and loans (mainly through Citibank), investment banking, brokerage, wealth management, alternative investments, and other financial services. Reeling from $90 billion in writedowns and losses on mortgage-related securities and other investments, Citigroup announced plans in early 2009 to split itself in two. The major reorganization will hive off its money-losing assets from its banking divisions.Risky subprime loans delivered a huge blow to the financial services giant. The mortgage meltdown forced Citigroup to post the worst fourth-quarter loss in its 196-year history: $10 billion. The company also had to write down $18.1 billion on mortgage-backed securities and cut its dividend by 41%. Chief Executive Charles Prince was shown the door, and the company's shares fell 47%, making it the worst-performing Dow Jones industrial average component in 2007.
