Mosaic Insurance, the Bermudian-based global specialty insurer, has appointed Taylor Denier to lead growth of its US environmental liability business.

Mr Denier joins the company’s New York office as SVP, head of US, Environmental Liability, reporting to global head Jim Finnamore, and is responsible for leading operational and growth strategy for Mosaic’s American portfolio.

The division also has environmental risk specialists in London and Toronto, with plans to build out the team further in coming months, the company said.

Mr Finnamore said: “We’re delighted to launch our local environmental underwriting capability in the US and to welcome Taylor to Mosaic.

“It’s exciting to respond to growing client demand by bringing leading capacity and deep expertise to the US market. Taylor’s hire is just the beginning of an ambitious growth plan that demonstrates Mosaic’s commitment to our environmental liability division.”

Mosaic launched its primary environmental insurance product line in October 2022, offering $25 million in lead-market capacity via Mosaic Syndicate 1609, along with syndicated capital from trade partners.

The company underwrites a suite of environmental insurance products, including site pollution, contractors’ pollution liability, and lenders’ liability, for a wide range of industry sectors and clients.

Supporting companies transitioning to more sustainable, low-carbon futures is also a key focus, Mosaic said.

Mr Denier has 20 years’ experience in the sector in North America, and has held brokering, underwriting and management roles in environmental liability, property and other casualty products.

Previously, he was a senior leader with Chubb’s environmental division and managed underwriting teams in Philadelphia and Pittsburgh. He started his career in the environmental brokering unit at Aon, Toronto.

Mr Denier said: “Environmental risks are evolving rapidly everywhere, and have become more relevant than ever to businesses today.

“Complex liabilities driven by factors like the emergence of hazardous chemicals and more volatile climate change are challenging to manage, and while the US market is well developed, in certain segments there’s a need for meaningful capacity, technical and underwriting skills, and experience.

“I’m thrilled to join Mosaic’s best-in-class team, and look forward to being part of the company’s growth plans to serve our clients.”

Outside the US, Mosaic said, its environmental division has built a strong market presence to date in key target territories of Canada, Britain, Australia, Central America and Europe.
