Two of the Big Four – Deloitte and EY – are currently examining the potential split of their accounting and consulting businesses to ease compliance pressure. A probable scenario would involve the consulting and tax businesses being spun off into a separate company in an IPO while the audit function would remain a partnership. This would lead to a tidy payout for partners, according to seniority.
