I'd love to write a long response as this is a topic of interest to me, but I'm short on time right now so I'll keep my thoughts brief.
In general, the commercial sector is wrestling with the mess it's in due to property depreciation that has affected many states, declining business revenues, and borrowers who are often in a weakened financial state.
To add to the problem, you have lenders who are dealing with fixing their balance sheets, trying to get rid of toxic assets, and in some cases, being watched/managed by the FDIC.
When you factor in the billions of commercial paper that is coming due just this year alone, you have a real mess.
However, banks seem to be more willing than before to take a haircut on a loan if they really want it off their books. Partly because it's often to their benefit and partly because sometimes the FDIC is looking over their shoulder.
For some borrowers being offered a reduced payoff often isn't enough. They still need to disclose their business financials and be credit worthy. Unfortunately, for a lot of borrowers they just don't pass muster which leaves them in a very precarious position when trying to secure a new loan.
It's going to be interesting to see what happens as the segment of borrowers who need to find a new loan, but cannot qualify for one grows.
So much for brief, lol.
