Arch Insurance Group, a member of Arch Capital Group, has completed its acquisition of Aon's managing general underwriter Wexford Underwriting Managers.

Arch Insurance entered into an agreement with Wexford Underwriting Managers on the first day of this year to write excess workers compensation business and employers liability insurance, and at the same time, Arch also entered into an asset purchase agreement to acquire the operations of Wexford from Aon Corporation.

That agreement included the renewal rights of the business. the deal was completed last Monday and the Wexford operation is now a division of Arch Insurance Group. It will be known as Arch Wexford.

Wexford, which was founded in 1985 and acquired by Aon in 1992, currently underwrites excess workers compensation insurance for qualified self-insureds.

According to Arch one of the key attractions of the Wexford business is its experienced management team and staff, who will now join Arch.

"They have a focused underwriting approach that targets specific industry segments such as healthcare, schools/universities, manufacturing, retail/wholesale, and governmental entities. Wexford writes both single entity and group self-insurance funds within these industry segments," said a newswire report.

Arch Wexford will report to John S. Edack, Arch Insurance Group regional executive vice president who is working closely with the Wexford team to ensure a smooth integration.

"We found this market niche attractive because the self-insured marketplace is growing on an annual basis," said Mr. Edack. "We are excited to be working with the Wexford team, which brings such deep expertise and continuity to this area of the market, and look forward to making this capability a vital part of our product offerings."
