One80 Intermediaries, a leading specialty insurance broker, has announced the appointment of Jonathan Legge as Senior Managing Director, Private Equity and Transactional Liability.
In this new role, Legge will be responsible for supporting One80’s retail trading partners in safeguarding insured parties from exposures associated with mergers and acquisitions.
His solutions will focus on helping buyers and sellers quantify and mitigate risks, enhance deal value, maximise financial returns, and address gaps in transaction structures. Areas of expertise encompass representations and warranties, tax insurance, contingent liability, and other strategic products.
Prior to joining One80, Legge served as the Executive Vice President at Ethos Specialty, where he led strategic relationships with a focus on third-party capital and broker relationships.
He also held the position of Senior Vice President at RT Specialty, working across various transactional risk and alternative asset insurance classes.
Legge’s career in the insurance industry began in 1992 with American International Group (AIG), and he later moved to Johnson & Higgins in 1996, which was acquired by Marsh in 1997.
During his tenure at Marsh, he rose to prominence as the leader of its FINPRO global private equity practice. In 2008, Legge co-founded Vanbridge, where he developed numerous insurance products specifically tailored to the private equity sector and continued to broker transactional liability programs.
“I am excited to join One80 Intermediaries at this stage in the firm’s maturity,” said Legge.
“I am confident that One80 will provide the Private Equity and Transactional Liability Practice with the financial resources to thrive, the support of a fantastic leadership team, an innovative operating platform, and a leading distribution network,” he added.
“Jon is a true industry expert who brings a wealth of experience, technical knowledge and relationships in the complex risk space,” said Matthew F. Power, President, One80.
“I look forward to him joining the One80 family as we continue to extend our expansive financial lines offerings to include M&A risks,” he continued.
