Mosaic Insurance has launched an excess casualty unit, expanding its underwriting platform to eight global product lines as demand for liability capacity continues to rise.
The new facility, based in Bermuda, began underwriting immediately and is intended to support large corporate and multinational clients facing higher liability costs, particularly in the North American market.
The excess casualty business will be led by April Andruczyk, who joins Mosaic as head of Bermuda excess casualty. She brings close to 30 years of underwriting and leadership experience in excess liability and general casualty. Most recently, she served as vice-president of general casualty at Allied World Assurance Company in Bermuda, where she was responsible for underwriting, portfolio management and broker relationships. Before that, she spent 18 years at ACE Bermuda, now part of Chubb, managing its excess liability division after beginning her career with the legacy Chubb Corporation in New York.
Mosaic said the launch reflects ongoing pressure in the excess casualty market, where insureds are contending with rising severity, nuclear verdict trends, litigation funding and broader social inflation. These factors have tightened terms and conditions and pushed buyers to seek additional capacity, particularly from Bermuda-based markets.
The underwriting team includes Bermuda-based specialists Andrew Watson and Chris Abraham, UK consultant Mike Warwicker, and junior underwriter Skyler Powell.
Watson brings two decades of experience underwriting large corporate accounts and previously held senior roles at AIG and ACE/Chubb. Abraham has more than a decade of experience in the Bermuda market, working with transportation, rail, oil and gas and energy utility risks, including Fortune 1,000 clients. Warwicker has over 40 years of experience across the US, London and Bermuda markets and was most recently head of excess liability at Chubb Bermuda. Powell, a Bermudian national, previously worked within Mosaic’s financial institutions unit in London before returning to Bermuda.
The excess casualty unit will target sectors including transportation, consumer goods, industrial manufacturing, utilities, construction, energy, hospitality, real estate and life sciences. Capacity of up to US$10 million per risk will be offered through Mosaic’s Bermuda platform, which forms part of its worldwide agency network and leverages Mosaic Syndicate 1609, supported by syndicated partners.
Mosaic’s leadership said the expansion was timed to coincide with sustained demand for reliable excess casualty capacity and reflected a deliberate effort to broaden the firm’s specialty portfolio. The insurer added that Bermuda remains a strategically important market for excess casualty due to its capital efficiency, long-term track record and global relevance.
With the launch, excess casualty becomes Mosaic’s eighth product class, joining cyber, environmental liability, transactional liability, political risk, political violence, financial institutions and professional liability. The company said the addition positions it to respond to evolving client needs as carriers reassess risk appetite and adjust capacity in response to ongoing loss trends.
