"We'll miss her greatly and wish her all the best in whatever she chooses to do next." JPMorgan also named Charlie Scharf a partner with One Equity Partners, its private equity arm. Scharf has served as CEO of the company's Retail Financial Services business, and Todd Maclin, the head of JPMorgan's commercial bank unit, will assume those responsibilities.
