Arch Insurance International, a provider of specialty insurance products, has announced the promotion of Maggie Munns to Head of Executive Assurance and Matthew Doherty to Director of Underwriting, Executive Assurance, both effective immediately.
Munns will be responsible for overseeing the underwriting operations for the Executive Assurance division, which includes Commercial D&O, SME D&O, Financial Institutions, and Transactional Risk.
Based in London, she will report to Mike Lay, Chief Underwriting Officer for Long Tail Lines at Arch Insurance International.
These promotions follow the relocation of Michael Chu to the US, where he will assume the position of Senior Vice President, P&C Programs at Arch Insurance North America.
Munns, an experienced underwriter, began her career with Arch Insurance North America in 2015 and moved to the London office in 2021.
Doherty, who joined Arch in 2005 and most recently served as Executive Assurance Underwriting Manager, will now report to Munns in his new role.
Lay commented: “Maggie and Matthew’s promotions are fully deserved. Maggie has continually demonstrated her leadership skills, deep technical expertise and ability to build long-term broker relationships. I have no doubt that our underwriting teams will continue to thrive under her leadership, and with Matthew’s ongoing support, as we continue to strengthen our relevance and market standing across our Executive Assurance lines.
I would also like to thank Mike for his successful leadership of the division over the last six years and commitment to building such an extensive and diverse Executive Assurance portfolio. We wish him all the best in the next chapter of his career with our colleagues at Arch Insurance North America.”
