Aileen Mathieson has been appointed group chief investment officer at Aspen Insurance Holdings Ltd.

The Bermudian-based re/insurer said Ms Mathieson will take up the post effective November 15.

She will be based in London and join the Group executive committee.

Aspen said Ms Mathieson takes up the role of CIO following the retirement of Bryan Astwood.

It added that Mr Astwood will continue as an advisor to Group executive chairman and CEO Mark Cloutier, and he will remain a director of Aspen Bermuda Limited.

The company said Ms Mathieson has more than 15 years of investment and financial experience and joins from Aberdeen Standard Investments where she was global head of Insurance.

Previously, she was CIO, UK Life for Zurich and during her career has also held senior finance roles at Nucleus Financial Group plc, Standard Life Group, Diageo plc and EMI Music. Ms Mathieson started her career at KPMG.

Mr Cloutier said: “I am delighted that we are appointing an individual of Aileen’s calibre as our new chief investment officer.

“During a time when we are seeing increased periods of heightened market volatility, it is important that we are managing our investment portfolio effectively and proactively to deliver positive investment returns, complementing our strategic focus on driving disciplined underwriting performance.

“Aileen brings an impressive track record in managing investments in the insurance sector and, with her excellent leadership experience and strong communication skills, I look forward to her being an active and engaged member of our executive team.”

Ms Mathieson said: “I’m excited to join Aspen; the opportunity to join a dynamic organisation with strong momentum and a clear vision for its future was compelling.

“I look forward to working with Mark and his team to lead the investment function and to delivering positive returns for the Group while continuing to support the business’ ongoing balance sheet strength.”
