Before looking at asset quality the problem to me is the level of debt relative to assets. This may have been fine while credit was easy but that has now changed and changed for some time to come.
BBI is now a foreced seller of assets to reduce debt and that puts it at a huge disadvantage in terms of negotiations with potential buyers. Whether or not thier assets as a whole are overinflated in the present market remains to be seen.
The market appears to have decided on BBI's potential to reduce its debt burden with sellers down to 3c. Moody's have also taken a dim view, reducing its rating. BBI probably stands for "bye bye investment" some might feel it means "buy buy it'scheap". I'm waving it away.
