Several insurance organizations announced leadership changes and appointments this week, spanning specialty underwriting, corporate board governance and reinsurance.

Carbon Underwriting hires a head of US casualty as it scales

Carbon Underwriting has named Phil Wooldridge (pictured, left) head of US casualty and deputy active underwriter, effective September 28.

Wooldridge joins from Gallagher Re, where he was head of reinsurance for program solutions, with prior roles as head of London US casualty at SiriusPoint and syndicate chief underwriting officer for reinsurance at MS Amlin.

The appointment follows a period of rapid growth for Carbon, whose revenues climbed from £150 million to £471 million between 2023 and 2026, alongside a recent growth equity investment from FTV Capital earmarked to support US expansion and the development of Carbon's Graphene data and analytics platform. 

For wholesale and London market brokers with existing Carbon relationships, a dedicated US casualty leader backed by fresh growth capital signals the syndicate intends to expand capacity for long-tail US casualty risk specifically, worth flagging to any client with placement difficulty in that segment. Wooldridge's reinsurance background at Gallagher Re and SiriusPoint also suggests Carbon may be positioning to support larger or more complex casualty programs than its current book reflects, a detail brokers with growing casualty accounts may want to raise directly with the syndicate.

Liberty Mutual adds a private equity co-CEO to its board

Liberty Mutual has elected Scott Sperling (pictured, right), co-chief executive officer of Thomas H. Lee Partners, to its board of directors.

Sperling has been with the Boston-based private equity firm since 1994 and has helped grow it to more than $50 billion in equity capital across more than 175 portfolio companies. He previously spent more than a decade managing Harvard University's endowment alternative asset classes and has served on the board of Thermo Fisher Scientific since 2006. 

A board-level governance appointment focused on capital allocation has no direct bearing on underwriting appetite or broker relationships in the near term. Brokers placing business with Liberty Mutual shouldn't expect any near-term change in service or pricing as a result of this addition.

Mosaic Insurance continues building out its North American finpro team

Mosaic Insurance has hired Risa Kleiner as SVP, financial institutions, and Daniel Frusciano as SVP, professional liability, expanding its US finpro team to a dozen specialists supporting a global team of 24 across London, Toronto and Bermuda.

Kleiner brings 20 years of underwriting, claims and legal experience, including leading the financial institutions business at Everest, while Frusciano spent more than two decades at Ambridge and Liberty Mutual/Ironshore leading financial lines and cyber underwriting teams.

The expansion continues a pattern of rapid product diversification at the five-year-old carrier, which Insurance Business has previously reported launched an excess casualty unit in January, becoming its eighth product class at the time. 

Brokers placing financial institutions and professional liability business now have two new primary forms to consider, the integrated asset manager policy and Innovator One, both structured to consolidate coverage lines that clients would otherwise have to place separately across multiple markets.

For brokers working with fintech, digital asset or asset management clients specifically, Mosaic's expanded New York-based team gives a growing, dedicated underwriting contact point worth testing on submissions that have historically required cobbling together D&O, E&O, crime and cyber coverage from different carriers.

5Star Life adds two industry veterans to its board

5Star Life Insurance has appointed Timothy Arnold and Kimberley Wooding to its board of directors, effective September 1.

Arnold spent more than 40 years in insurance, most recently as executive vice president of voluntary benefits for Unum Group and president of Colonial Life. Wooding retired from 5Star Life itself after nearly three decades with the company, most recently as executive vice president and chief financial officer.

5Star Life distributes primarily through AFBA's membership base of military and government-affiliated clients rather than a traditional independent broker channel, so this board addition has limited direct relevance for most commercial or personal lines brokers. Advisors serving military and veteran clients specifically may find Arnold's voluntary benefits background at Colonial Life a useful signal of where 5Star Life's product strategy could evolve.
