President and CEO, Reinsurance Group of America, 60
Even in the face of persistently low interest rates in the U.S., Manning has continued to grow the top life reinsurer. Reinsurance Group of America’s revenue increased 9% in 2017 to a record-breaking $12.5 billion, thanks in part to the company’s push into Asia. That business grew 33% last year amid rising interest in reinsurance in the region. Still, Manning’s job is not without its challenges. A deadly flu season in North America kept earnings subdued, heading into early 2018.
