Vikram Pandit forced out as Citigroup chief: Reports

Pandit, who steered the crisis-hit Citigroup into profitability, resigned abruptly on Tuesday -- a development that took the Wall Street by surprise.

According to media reports, Pandit's exit came in the wake of differences with the board.

"Pandit's resignation came after a series of missteps this year left some directors feeling that the company wasn't being managed effectively and that the board wasn't kept adequately informed," the Wall Street Journal said quoting sources.

In a similar tone, the Financial Times said that Pandit left Citigroup after a clash with the board over a series of recent missteps by the bank.

Citing sources, FT said the underlying issues behind Pandit's exit include "Citi's failure to pass Federal Reserve stress tests earlier this year, a defeat on a 'say-on-pay' vote by shareholders and the handling of the sale of the bank's stake in Smith Barney, the retail brokerage, to Morgan Stanley."

In an abrupt exit, Pandit resigned after nearly a five-year tenure during which he steered the third-biggest US bank through difficult years after the 2008 financial crisis.

"The action raises questions about whether the sprawling Citigroup empire ultimately will be dramatically pared back or broken up, something Pandit opposed," the WSJ said.
