I was about to say aren't there only 4 auditing agencies in the entire US after the fifth fucking imploded after the Enron scandal due to their reputation being tarnished?
No, there are more. But auditing an S&P500 corporation is pretty complex. I am not in the auditing S&P 500 corporation business and it looks like there may be six - but the Big4 literally seem to do 491/497 companies.
I’m not sure I am too concerned about the auditing quality of the Big4 tbh though…
Enron’s problem was the “consulting AND auditing” mess with conflict of interest if I am not mistaken.
