Some good stuff here! .... but we must separate what goes on in different KPMG operations around the world.... it is not clear whether the Dubai businesses set up was KPMG- Dubai or KPMG -SA... and if SA, whether it was the Audit side or the Tax / Consultancy operation.
I cannot see how those involved with the Gupta audits were not complicit or implicated, especially regarding the Wedding expenses... not part of producing income, not allowed as a tax deduction!! 
I suspect KPMG International are hugely aware of illegal practices and thereby fines from the USA. 

There has to be much more disclosure iro SARS and the Gupta audits.... there's more than reputation at stake! The investigation should have a timeline.... say 3 -4 months.... i would far prefer to see something 95% + probability soon than 96% + probability in 2 years time.
