During the major financial crisis beginning in late 2008, Citigroup suffered large losses in its retained collateralized debt obligation exposure (loans that Citi underwrote but was not able to sell), and had to be rescued by the U.S. federal government. They decided to sell or close "non-core" businesses in order to raise money. On January 13, 2009, Morgan Stanley and Citigroup announced the merger of Smith Barney with Morgan Stanley's Global Wealth Management Group, with Morgan Stanley paying $2.7 billion cash upfront to Citigroup for a 51% stake in the joint venture. The joint venture operates as Morgan Stanley Smith Barney. Morgan Stanley itself was in a financially cash-strapped position like Citigroup during that time, but they were helped by $9 billion for a 21% stake in Morgan Stanley.
