Allison Dukes

Allison Dukes says she will not be joining the combined company because she wants to remain in Atlanta, where she is involved with several civic and philanthropic organizations. The merged company will be headquartered in Charlotte, N.C.

A promotion to CFO in March, which made Dukes the first woman to hold that job in the company's 127-year history, was in large part a recognition of a job exceptionally well done in her previous role as head of commercial and business banking.
