I like RFG, page-65

If trade creditors stand to get nothing in the event of an administration then they could cause problems for the banks as the administrator is bound by creditor resolutions with must pass by a majority of numbers and dollars. In the case of the Paladin Energy administration, a couple of years ago, the unsecured creditors stood to get nothing so they voted to convert debt to equity. I know this sounds very hypothetical at this stage but given that banks don't have mortgages over hard assets, they would probably prefer to avoid administration issues.
