Bermudian-domiciled Athora Holding Ltd, an insurance and reinsurance group focused on the European market, has appointed Michael Koller as group chief risk officer.

He succeeds Lukas Ziewer, who stepped down as group CRO in May.

Mr Koller, who will become a member of Athora’s management committee subject to regulatory approval, is joined at Athora by Chantal Waight who has recently taken up the role of managing director of group risk.

Mr Koller has more than 30 years industry experience and was most recently CRO at MS Amlin.

Previously, he was group risk director at Prudential plc for almost a decade, where he also served as a member of key subsidiary board audit and risk committees.

Before joining Prudential plc, Mr Koller served as CRO for Aviva’s European operations, where he built and led the risk team.

Ms Waight has 25 years’ insurance industry experience, the last 15 of which were at M&G plc and Prudential plc, most recently as director of strategy & corporate development for M&G and director of investor relations for Prudential.

She also has deep experience of investment markets through her senior roles at M&G Investments, Athora said.

Mike Wells, the group CEO of Athora, said: “Robust risk management is central to our business model. The appointments of Michael and Chantal adds two seasoned senior leaders to our risk function.

“They join Athora at an exciting inflection point and will each play an important role as we prepare for the next phase of our growth and maturity journey.”

The company said the appointments followed a transformational 12 months for Athora in which it completed acquisitions in Italy and Belgium, signed a large acquisition in Germany, raised approximately €2.75 billion of common equity capital and completed its inaugural bond issuance in public capital markets.
