Ascot Group Limited, the Bermudian-based global specialty insurance company, has appointed Mark Wilcox as its new group chief financial officer.

Former RenaissanceRe executive Mr Wilcox will report to group CEO and president Jonathan Zaffino.

He takes up the post on November 8, succeeding Joe Roberts.

In his new role, the company said, Mr Wilcox will be responsible for leading Ascot's global finance organisation and capital strategy, including all financial planning and analysis, tax and treasury functions.

Mr Zaffino said: "I am thrilled to welcome Mark to the Ascot family. Mark's unique and diverse experiences, along with his undisputed track record of success, will help accelerate Ascot's strategic pursuits and ambitions.

"As we continue to expand our organisation globally, across both the specialty insurance and reinsurance segments, Mark's proven financial acumen will be a significant addition to our leadership team, our colleagues and our valued clients."

The company said Mr Wilcox joins Ascot from Selective Insurance Group Inc, where he led the firm's global finance operations and capital management strategy, as well as accounting, treasury, investor relations, internal audit, investments, reinsurance, enterprise risk management, procurement, contracts and tax, in his role as executive vice president and chief financial officer.

Prior to joining Selective, Mr Wilcox spent over 13 years at Renaissance Re in Bermuda where he served as senior vice president, corporate controller and chief accounting officer.

Mr Wilcox will be based in Ascot's Stamford, Connecticut office.
