JPMorgan Chase has a new chief financial officer, Marianne Lake, who has been the CFO of the bank’s retail unit since 2009.
In her new role, Lake — who will join an elite club of C-level women on Wall Street — will be tasked with managing the bank’s books and keeping certain cetacean creatures away from the bottom line.
