Mosaic Launches Bermuda Excess Casualty Unit
“Mosaic Insurance has launched an excess casualty unit, its eighth global product line, and hired specialist April Andruczyk to lead the business from Bermuda.
A spokesperson said, “The facility, which begins underwriting immediately, will provide support to large corporate and multinational clients facing rising liability costs, particularly in the volatile North American market.
“Mosaic’s new team includes two additional Bermuda-based specialist underwriters, Andrew Watson and Chris Abraham, along with UK consultant Mike Warwicker, all experts in the class of business, and Bermudian junior underwriter Skyler Powell. The strategic buildout broadens Mosaic’s portfolio beyond its seven foundational specialty lines to meet growing client demand in the casualty space and deliver long-term value.

“Target industry sectors will include transportation, consumer goods, industrial manufacturing, utilities, construction, energy, hospitality, real estate and life science, with capacity up to USD$10 million per risk, available through Mosaic’s Bermuda platform—part of its worldwide agency network that leverages Mosaic Syndicate 1609, supported by syndicated partners.”
“We are excited April will drive our new venture forward,” said Mark Wheeler, Co-CEO at Mosaic. “This strategic expansion comes at a time when the excess casualty market faces ongoing challenges, and the need for reliable capacity remains elevated. Our approach has been carefully considered and, like all our lines, leverages the most outstanding talent—this time, in complex excess casualty. We have strong aspirations for the product to become a significant line of business for us.”
The spokesperson said, “Andruczyk, appointed Head of Bermuda, Excess Casualty, has close to 30 years of underwriting and leadership, with deep expertise in excess liability and general casualty. Most recently, she served as vice president of general casualty at Allied World Assurance Company in Bermuda, responsible for underwriting, portfolio management, and strategic brokerrelationships. She spent 18 years prior with ACE Bermuda [now Chubb], managing its excess liability division after starting her career at the legacy Chubb Corporation in New York, where she held senior underwriting roles.”
“April is a highly respected market leader with extensive technical knowledge and enduring broker and client relationships,” said Toby Smith, Mosaic’s CEO, Americas. “We are also pleased to welcome Andrew and Chris, with support from Mike, who, collectively, bring many years of experience and market insights to support our team as we build out this new line. There are exciting opportunities ahead, and we look forward to delivering solutions that meet the evolving needs of this dynamic market.”
“I’m thrilled to be joining Mosaic at such a pivotal time in the industry,” said Andruczyk. “I’m especially energized by the opportunity to collaborate with outstanding professionals and contribute to a company that is exceptionally well-positioned to respond to the current needs of the complex casualty landscape.”
The spokesperson said, “Bermudian Watson brings 20 years of insurance experience, underwriting Fortune 1000 accounts and handling broad books of business. Most recently, he was a senior vice president of excess casualty at AIG and previously worked at ACE/Chubb. He started his career in London as a reinsurance broker for JLT Re’s non-marine treaty team.
“Abraham, also Bermudian, has worked in the Bermuda market for more than a dozen years, beginning his career at Integro Insurance Brokers before joining Chubb in 2020. He has worked with a variety of Fortune 1,000 clients, focusingon transport, rail, and the oil and gas sector, including energy utilities.
“Warwicker has over four decades in the US, London, and Bermuda markets, specializing in excess casualty. He was most recently senior vice president, head of excess liability, at Chubb Bermuda, where he helped expand the firm’s portfolio of high-excess casualty business.
“Powell, a Bermudian former intern at Mosaic, began her underwriting career with the firm’s financial institutions unit in London, and now returns to Bermuda to join the new team.
“Excess casualty insurance terms and conditions have remained tight amid continued pressure from nuclear verdict trends, litigation finance, and social inflation, driving insureds to look towards Bermuda for additional capacity. The excess casualty sphere continues to demand evolving strategies, including recalibrating capacity and rising rate and severity trends, prompting carriers to reassess exposures and become more selective in their risk appetites.”
“Bermuda remains a durable, strategically important platform for excess casualty,” Warwicker noted. “This market is supported by a long-term track record, capital efficiency, and growing global relevance.”
The spokesperson said, “Excess casualty becomes the eighth product class at Mosaic, joining cyber, environmental liability, transactional liability, political risk, political violence, financial institutions, and professional liability.”
