Fifth Third Bancorp in Cincinnati has appointed a Humana Inc. executive to its board.

Michael B. McCallister joined the Louisville, Ky.-based Humana in 1974 as a finance specialist, the $115 billion-asset Fifth Third said in a press release on Wednesday. He became its chief executive in 2000 and chairman a decade later after holding numerous positions at the health care company.

McCallister's appointment brings the number of directors on Fifth Third's board to 14.

"Mike is an accomplished executive who progressed through the ranks of Humana. Under his leadership Humana was transformed from a hospital company to one of the health care industry's leading consumer companies," William Isaac, chairman of Fifth Third, said in the press release.
