First thing KKR could do is refinance QIN's debt. They could probably get interest rates much lower than QIN's 8.5% which would be an immediate substantial cost saving.
And recall the speculated value of Santalis from the JPM presentation of $US300-$US500m (I think). That represents $1.00-$1.60 of QIN share price value. And KKR would have a far bigger contacts list of potential buyers than QIN.
So that's my reckoning as to who approached Frank Wilson. We will see
