Its not about debarring or punishing PWC, thats not our job. But we should clearly see that what conditions existed that were responsible for such an act by PWC(a worldwide reputed firm). If its fraud, anti fraud measures need to be strengthened so that any other firm doesn't repeat it.
If its negligence and PWC people were fooled or deceived by satyam , then it is a deeper matter and the situations that led to negligence by the firm should be studied.
This scam proves that the antifraud measures taken after arthur anderson case were not sufficient.Otherwise this would have not happened.
Thus we should discuss about the additonal cautions we should take in future audits to avoid anything like this.
