(Bloomberg) -- Citigroup Inc. faces losses of as much as $180 million on loans made to an Asian hedge fund whose foreign-exchange wagers went awry, prompting board-level discussions and a business shakeup, according to a person briefed on the matter. The hedge fund and Citigroup are in discussions on the positions and how they should be valued, said people with knowledge of the talks, who asked not to be identified because the discussions are private. The situation is fluid and the eventual losses may end up being smaller depending on how the trades are unwound, one of the people said.
