Size matter in audits of listed companies

By Richard Crump, AccountancyAge


Big four rivals KPMG and PwC have dominated the listed audit market over the last decade, according to the 2015 corporate adviser ranking guide.

Over the last ten years, KPMG has ousted PwC from top spot by way of client numbers, though PwC remains by far and away the most successful auditor when judged by the aggregate market-cap of its clients. Deloitte and EY retained their respective standings over the ten-year period, but with greatly reduced client counts.

The news that KPMG has been the most prolific plc auditor over the last decade – growing its total stock market clients to 412 from 354 – comes as accounting watchdog the FRC announced plans to investigate KPMG’s work as auditors of failed bank HBOS. In the same period, PwC, EY and Deloitte saw their share of listed clients shrink.

PwC remains the top FTSE 100 auditor in terms of number of clients and total market cap – a position it has held for the entire period – followed by KPMG, Deloitte and EY.
