American International Group (AIG) said today that former Lloyd’s CEO John Neal is joining as president, effective December 1.
Neal, who at the start of 2025 was named CEO of reinsurance at Aon, will lead AIG’s General Insurance—North America and international commercial insurance businesses plus AIG’s global personal insurance book.
AIG said Neal will report to Chairman and CEO Peter Zaffino, and he will become a member of AIG’s Executive Leadership team.

“I have known John for more than 20 years, and he is widely recognized as one of the most accomplished insurance executives in the industry,” Zaffino said in a statement. “His appointment adds significant depth, global underwriting experience, and talent to our leadership team. I am confident that John will continue to enhance our culture of underwriting excellence.”
“I am honored to take on the role of president and look forward to working closely with Peter and AIG’s talented colleagues around the world on behalf of our clients and stakeholders,” added Neal.
Neal served as CEO of Lloyd’s of London since October 2018, and was to start at Aon as global CEO of Reinsurance and chairman of Climate Solutions at the end of his notice period at Lloyd’s. Only a month ago, posted about his last day.
Apparently there are no hard feelings, as Aon CEO Greg Case said in a statement that he wished Neal “great success” and looked forward to working with him.
The roles of Don Bailey, CEO of North America commercial insurance, and Jon Hancock, CEO of international commercial Insurance and the global personal insurance business, do not change.
Meanwhile, Aon announced a series of appointments within its reinsurance business. Aon said the moves are unconnected to Neal’s decision to switch to AIG before starting at Aon.
