Mullin, who joined AEGON in 1987, currently heads AEGON's pension operations in the United States, as well as AEGON's U.S. annuity and mutual fund businesses.
Mullin will report to Pat Baird, the current CEO of AEGON Americas, who will continue to maintain direct responsibility for AEGON's life reinsurance business.
"The Americas are vital to the success of AEGON's long-term strategy," says Alex Wynaendts, AEGON's CEO. "Mark's extensive knowledge of our businesses there, and his strong track record will be a tremendous asset as we strengthen our position in what continues to be the world's largest market for life insurance and pensions."
