Ascot Group has announced the appointment of Rosalind Brewer (pictured above, left), Martin Flanagan (pictured above, right), and Robert Sewell to its board of directors, subject to regulatory approval.
The Bermuda-based specialty re/insurance company said the additions aim to expand board oversight as the firm continues to evolve its leadership and strategic governance.
Brewer is currently interim president of Spelman College and a board member of United Airlines Holdings, Inc. She previously served as CEO of Walgreens Boots Alliance from 2021 to 2023, leading a workforce of more than 450,000 employees worldwide and overseeing several acquisitions.
Her previous executive roles include senior positions at Starbucks Corporation, Walmart Inc., and Kimberly-Clark Corporation. She has held seats on multiple corporate boards throughout her career.
Flanagan is chairman of Engage Ventures, LLC, a venture capital platform supporting startup firms. He was previously president and CEO of Invesco from 2005 to 2023, and served as chairman emeritus from 2023 to 2024. At Invesco, he led the acquisition of OppenheimerFunds.
Flanagan is a CFA charterholder and a certified public accountant. He has also served on the board of governors and executive committee of the Investment Company Institute.
Sewell currently serves as chairman of the board at Ascot Underwriting Limited (AUL), a UK-based subsidiary of Ascot Group. He joined AUL as an independent non-executive director in July 2023 and assumed the chair role in June 2024.
Previously, he served as CFO of Pension Insurance Corporation from 2008 to 2021 and held an independent director position at AIG Life Limited, where he chaired the Board Audit and Risk Committee. Sewell will continue as chairman of AUL alongside his new responsibilities.
"Ascot Group, our colleagues and clients, will all benefit from the strategic expertise, leadership qualities and vast experience that Roz, Marty and Rob bring to our organization. I am excited to collaborate with each of them," said president and chief executive officer, Jonathan Zaffino.
The board expansion follows a series of senior leadership moves within Ascot’s underwriting division. In January, the company named Eric Herman as group head of underwriting performance management and appointed Jon Mosby as deputy chief underwriting officer for US marine and property lines.
Earlier this year, Fitch Ratings affirmed its assessment of Ascot Group and its operating subsidiaries by assigning a rating that reflects the company’s underwriting stability and financial standing.
