Are you asking because you work for KPMG?
The way Simon Crane explained his role as auditor at the HML AGM was that HML shows him the info they want him to sign off on, he checks that it adds up and then signs off on it. He's more like a proof reader than an author. I think KPMG have tried to limit their liability as much as possible by raising concerns with the most recent annual reports, but I do think they dropped the ball by not raising the same or at least similar concerns a year earlier. I do think they'll cop some serious flak for the 2017 audited report.
