Financially troubled Citigroup may soon be getting a new chairman, and possibly even a new CEO.

Citigroup yesterday named a new leadership team, whose mission will be to pull the company out of staggering debt from the mortgage crisis.

Vikram S. Pandit was appointed CEO, and Winfried F.W. Bischoff became chairman. The two men succeed Charles Prince, who resigned after reporting up to $11 billion in new losses.

The speculation over who fills Richard Parsons’ CEO job at Time Warner Inc. is over, as Jeffrey Bewkes has been named company chief, effective Jan. 1.

Now the guesswork begins over what Bewkes, currently Time Warner president, will do to improve performance at the media giant. Indications are that Bewkes will come out swinging.
