Wells Fargo, the most valuable US bank, paid a board member’s son about $1.4 million last year for his work in a unit responsible for investing deposits.

Scott P. Quigley, 44, received the compensation as a manager in the principal investments group, according to the San Francisco-based lender’s most recent proxy filing. His father, Philip J. Quigley, a Wells Fargo director since 1994, is retiring from the board in April. Scott Quigley declined to comment, and his father didn’t respond to messages seeking comment. The bank declined to make them available.
