Ally is chartered in Utah. However the CEO of Ally, I think, used to be the CFO of the Charlotte B0A bank.
If you look at the Ally Bank website it states the corporate headquarters is in Detroit. The website lists regional headquarters in Salt Lake, among other cities including Charlotte.
Michael Carpenter, CEO of Ally, per the corporate officer biography previously worked at Citicorp, GE Capital, Travelers Insurance and his own investment firm. He became CEO in 2009. No mention of BOA in his resume.
Jeffrey Brown, who became President and CEO of Ally’s dealer finance division in March 2014, was Treasurer of BOA in Charlotte prior to joining Ally in 2009 in a corporate planning role.
