One of my favourite City Commentators, 
Anthony Hilton, 
writes in his Evening Standard column that it would be in 
EMI's interest that 
Terra Firma and 
Citigroup 'talk' to resolve their dispute. But all too often these negotiations are a win-win situation for the over-leveraged borrowers. Any concession by the lender is in effect a gift as the really logical situation would be a write-off of the equity and the transfer of ownership to the lenders. This would  also be beneficial from a societal point of view as it would redistribute wealth  in a more equitable way, preventing capitalism from becoming a one-way bet for the borrowers.  
From a business point of view, banks  must look after their profits, this benefits not only their shareholders but  also taxpayers as any capital cushion they build up will also reduce the amount  of any future bailout that may be required.
