Robert Teh,

should give u the answer.
IMHO, i think the question on why is it difficult to identify
coporate misbehaviour is not appropriate.
The set-up of a company (with the Shareholders, directors, Non
Executive directors, chairman, Board of directors, audit committee,
renumeration commitee) is suffice as a check with each other
function.
However, it is not the system... it is the ppl running the co. tat
is the problem.
