(April 4): Credit Suisse Group AG leaders are discussing replacing chief risk officer Lara Warner, after a string of miscues at the bank led to losses potentially totalling billions of dollars, according to people briefed on the matter.

The bank is expected to give investors an update on the impact of its exposure to the collapse of Archegos Capital Management and the fallout for Warner and other top executives this week, said the people, who asked not to be identified describing private plans. Chief Executive Officer Thomas Gottstein is expected to stay on, the people said.
