A number of executives will leave XL Group in the coming months in anticipation of the completion of the $15.3 billion takeover of the company by Axa, the French multinational insurance company.

Susan Cross, chief actuary, and Kristin Gould, general counsel, who are both based in Bermuda, together with Paul Jardine, chief experience officer, and Eileen Whelley, chief human resources officer, are expected to leave XL at or shortly after the close of the transaction with Axa.

The departures and a number of changes to the XL Catlin Leadership Team and XL Group Leadership have been detailed in an SEC filing.

In the filing Mike McGavick, chief executive officer, and Greg Hendrick, XL president of P&C, said: “We want to take this opportunity to thank Susan, Kirstin, Paul and Eileen for their many contributions. They have each played a unique role across the company.”

In addition, Doug Howat, chief executive, global lines, and Paul Brand, who currently leads Accelerate, have decided to leave the company.

Mr McGavick and Mr Hendrick, said: “Their dedication was critical in creating XL Catlin and in making it a success. We wish them well in their future endeavours.”

Changes being implemented will see Neil Robertson and Jason Harris, currently chief executive insurance underwriting and chief executive international insurance, each take on new roles as chief executives for global speciality and global P&C respectively.

Kelly Lyles will continue as chief executive for client and country management and will add communications and marketing to her remit.

In the SEC filing it was stated: “We intend to create a more connected data and analytics group, including some of our innovation efforts, led by Paul Shedden, currently chief executive insurance pricing and analytics. In addition to strategic analytics, led by Kim Holmes, effective July 1 Paul’s team will include Enterprise Data, led by Henna Karna, as well as Accelerate, led by Vincent Branch.

“For some time we’ve thought of bringing the analytics, data, and innovation work closer together and this is a good opportunity to take that step.”

Among changes planned for the XL Group Leadership team, Steve Robb will continue as CFO and will oversee investments, led by Andre Keller. It is also expected that Mr Robb will oversee actuarial reserving at the departure of Ms Cross, to be led by Jean-Luc Allard.

Sean McGovern, currently XL Catlin’s chief compliance officer and head of regulatory and government affairs, is expected to add responsibility for compliance, leadership for claims and legal, after the departure of Mr Jardine and Ms Gould.

Meanwhile, Nikki Gonzalez, currently senior HR business partner, is expected to lead human resources after the departure of Ms Whelley.
