Mosaic Insurance has assembled a special team to lead a new excess casualty unit out of Bermuda.

The company’s eighth global product line is up an running and the company has hired specialist April Andruczyk to lead the business from the local office.

The new division will provide support to large corporate and multinational clients facing rising liability costs, particularly in the volatile North American market.

Target industry sectors will include transportation, consumer goods, industrial manufacturing, utilities, construction, energy, hospitality, real estate and life science, with capacity up to $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.

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 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.

Appointed head of Bermuda, excess casualty, Ms Andruczyk has close to 30 years of underwriting and leadership experience, with deep expertise in excess liability and general casualty, the company said.

Most recently, she served as vice-president of general casualty at Allied World Assurance Company in Bermuda, responsible for underwriting, portfolio management and strategic broker relationships.

She spent 18 years 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.

Mark Wheeler, co-CEO at Mosaic, said: “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.”

Toby Smith, Mosaic’s CEO, Americas, added: “April is a highly respected market leader with extensive technical knowledge and enduring broker and client relationships.

“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.”
