According to Bloomberg, JPMorgan Chase (JPM) CEO Jamie Dimon stepped down as chairman of the lender’s main banking subsidiary at the start of July.

Dimon, who serves as CEO and chairman of the parent company, handed off his post at the unit to William C. Weldon, a JPMorgan board member and former head of Johnson & Johnson, said the person, who asked not to be named because details of the move weren’t announced. A regulatory document released yesterday listed Dimon as “chairman emeritus” of the subsidiary, which runs JPMorgan’s deposit and consumer banking operations.
