Abrash said: “I am honoured to serve as the next chair and CEO of Deloitte & Touche LLP.

Peirson currently serves as COO for Deloitte Consulting LLP. Previously he served as the COO for Risk and Financial Advisory and deputy CFO of Deloitte US. He said: "Uncertainty is a given in today's complex global business environment, but, when managed well, that 'uncertainty' can also breed innovation and disruption.

“I look forward to working alongside our professionals as we help clients manage cyber, transactional, regulatory, accounting, technology and financial crime, and other risks — changing the game in their industries while they do it."

Abrash will succeed Joe Ucuzoglu, who has been elected CEO of Deloitte US, and Helfrich will succeed Janet Foutty, who has been elected chair of the Deloitte US Board of Directors.
