ICG is a special asset manager and FTSE 250 company. Founded in 1989, it now commands €35.2bn (£30.6bn) of assets in third-party funds and capital.
“We are delighted to include ICG amongst our UK financial services audit clients,” said Omar Ali, UK financial services leader for EY.
“We recognise that choosing the right auditor has been an incredibly important decision for ICG and as a result we are proud to have been selected from among the competition,” he added.
EY will replace fellow Big Four firm Deloitte, who have audited ICG since it commenced trading.
The firm adds ICG to a long list of large financial services organisations including the Audit Commission, the Co-operative Bank, Foreign & Colonial, Land Securities, the London Stock Exchange, Nationwide, Phoenix, Royal Bank of Scotland, Sage Group, Sainsbury’s, Sainsbury’s Bank, Schroders, Standard Chartered and Wesleyan.
The firm also audits other large UK companies including the BBC, Dyson and Royal Dutch Shell.
In 2016, the former director and chairman of the audit committee and chartered accountant Kevin Parry was appointed as chairman of ICG.
