By Muskan Arora

The $108 billion Sompo International Holdings, property and casualty reinsurance provider, named Thomas Leone as its CIO, effective October 1.

Leone will succeed Mark Silverstein, who retired after being at the firm for eighteen years. The new CIO will report to Nicolas Burnet, the chief financial officer of Sompo.

“The combination of his technical expertise, strategic vision and strong leadership skills makes him the perfect fit for this role,” said Burnet, in a recent press release.

Currently, Leone is serving as a CIO at Partner Re, a role he took over in February 2021. He started at Partner Re in April 2013 as a portfolio manager, and then progressed to being the head of public fixed income in February 2019 and got his final promotion after two years as a CIO.

Prior to that, he was at Genworth Financial for six years, where he spent three years serving as a derivates trader for the asset liability management team. In the same firm, he has also held positions of derivates project manager and derivates analyst.

He has also served as senior project manager at Fidelity Investments for almost two years and worked as a senior software engineer at the firm before taking over the role.

As the firm undergoes staff changes, Sompo appointed Malwine Tewes as the head of risk control for its Continental Europe Commercial P&C insurance business, as per a press release on May 31.

The firm operates in 25 countries and offers commercial and consumer P&C reinsurance.
