Prior to the acquisitions, Mick was a Partner on Deloitte’s Restructuring team with a focus on the Financial Services industry. He has over 20 years’ experience in the Insurance industry working both within the Big 4 and as part of management teams within insurance companies. Prior to joining Deloitte in 2020, he was COO of a global specialty (re)insurer with Lloyd’s, company market, and US underwriting platforms.

He is highly familiar with the insurance run-off market having worked both buy-side and sell-side, and as an adviser and principal in both the solvent and insolvent markets.

Mick also spent 2 years as the CFO of one of the UK’s largest non-life insurance run-off portfolios. During that time, he led initiatives to create value and de-risk the balance sheet – commutation programs, reinsurance asset management, and portfolio exits. He was also responsible for the pro-active oversight of outsourced run-off managers.

Mick is experienced in dealing with distressed and insolvent insurance companies and other FS businesses and has implemented a variety of restructuring processes, including both solvent and insolvent schemes of arrangement.
