How a Limited Company works as a Auditor ? (eg PWC is a Ltd Co)?

Question

As per ICAI rules only partnerships and indivituals can act as Auditors. Then how PWC , KPMG, Earnt&Young which are limited companies , act as auditors in INdia

Answer 1

As far as I know, the Big 4 are structured as LLPs. They wouldn't want to be companies cos that would mean they need to be audited and no way will they allow that. Their profit and methodology are all highly confidential.
