Just to clarify my previous post, my opinion is based on:
1/ Am credit analyst for a living, so obv read a ton of auditor reports. The auditor reports usually correctly assess the major risks/elements, but mitigation/conclusion on the risks is very optimistic pretty much all of the time. I understand that it's not necessarily the auditor's job to be highly critical, either, especially since a critical auditor report is a big deal.
But the end result for 99,9% of auditor reports for large corporates is basicly that the auditor report says "we did all the checks checks and sparred with management, and the results are satisfactory", and I think there is a lot of value left on the table.
Obviously, it's hard to judge how much shittier the world would be if the audit process was not there in the modern world, so I might be too critical
.
2/ Have had to interact closely with external & internal audits on the job (though I'm not management, so not involved in the whole process). I work as a credit analyst in a business active in financing, so it's an important part of the audit. From my experience, the external audit is a joke compared to internal audits. The internal audits are always extremely well done, and identify most of the issues even if they're not easy to identify. The external audit is a "box ticking"-process.
Is there any research done on how good external audit firms on predicting fraud/inconsistencies/financial issues? Would be interested to see it, and wouldn't mind if it changes my mind.
