Speciality managing general agent Arcadian Risk Capital has made Mark Butler executive vice-president to lead the firm’s expansion into the American management liability market.

In connection with the appointment, Arcadian has secured Lloyd’s coverholder status and multiyear capacity to support the expansion.

Mr Butler joined Arcadian, which has offices in Bermuda, with all underwriting agreements in place and has commenced underwriting.

Based in New York, he brings an impressive underwriting track record and will head Arcadian’s mid-market ML initiative, Arcadian said.

The programme will focus on both primary and excess placements, including blended cover structures.

Mr Butler joins from AmTrust where he was head of AmTrust Exec, with responsibility for Specialty Lines ML. Before that, he was instrumental in the build-out of Specialty Lines ML at Euclid.

Arcadian chief executive John Boylan said Mr Butler is a consummate professional with a strong track record of disciplined underwriting and market-leading results.

“This initiative complements Arcadian’s existing product offerings and further strengthens the company’s speciality underwriting platform,” Mr Boylan said.

Mr Butler said the firm has secured high-quality carrier support for this product line. He looked forward to executing in accordance with Arcadian’s strategic plan.

Arcadian announced last October that it had entered a strategic partnership with Lee Equity, a growth-oriented, middle-market investment firm specialising in investments in the financial and healthcare services sectors.

Arcadian underwrites several speciality classes of business across general liability, professional liability and property insurance lines.

The firm said it has built an underwriting-centric business, combining strong technical expertise, a disciplined approach to risk selection and intentional portfolio construction to deliver long-term value to its carrier, insured and broker partners.

Now entering its sixth year in business, Arcadian is approaching $2 billion of aggregate gross written premium generated on behalf of its carrier partners.
