This is not necessarily true. There are profitable components within SGH that can be spun off and bought by PE. If a PE firm decided to make a bid for those profitable businesses the banks could call in the debt and take a fair percent of the money owed. This is likely to happen if they otherwise don't believe SGH will ever repay the debt (it will especially happen if they believe SGH will need to withdraw even more).
