MS Amlin Underwriting, the Lloyd’s re/insurer, has appointed Johan Slabbert as chief executive officer. 

Slabbert will take up his post on November 1, 2020, subject to regulatory approval, succeeding Tom Clementi, who will step down from his position on October 31, 2020, after four years in the role. 

Slabbert brings more than two decades of leadership experience in the international re/insurance market, having held several chief executive and chief financial officer roles. He first joined MS Amlin Underwriting in May when he was appointed as a non-executive director and chairman of the board. He began his career at AIG, before joining Chaucer, first as chief financial officer and then as chief executive. He has also served as operating partner and chief executive of Augustus Specialty. 

He has also served as chairman of Mitsui Sumitomo Insurance Company (Europe) since 2017.

Clementi will pursue other opportunities outside of MS Amlin, but will remain with the business until the end of the year to support a smooth transition and regulatory handover. He has led MS Amlin Underwriting since late 2016, having originally joined MS Amlin in 2007.

Slabbert will step down from his position as chairman of the MS AUL board, with Martin Hudson, currently a non-executive director for the business and chair of the underwriting oversight committee, serving as interim chairman, subject to regulatory approval.

Tamaki Kawate, director and senior executive officer at Mitsui Sumitomo Insurance Company, said Clementi had played a vital role as chief executive in transforming and reshaping the business in challenging circumstances, and laid the groundwork for future growth. 

Kawate described Slabbert as “a recognised leader in the insurance sector with rich international experience and a strong track record of successfully managing and delivering growth for high-profile businesses, including Mitsui Sumitomo Insurance Company (Europe).”
