Let's say you have a claim for a $1000. It is estimated that the estate only has funds to pay you 40% or $400. You don't want to wait 6 years to get that $400 so you offer to sell you claim for $300. That leaves the estate with an additional $100 for distributions to other creditors.
If that doesn't make sense to you, then it isn't that it doesn't make sense, it is that you don't want it to make sense.
This is the same as the "convenience claims". I held a class 3 senior unsecured bond. Actually 3 them in three separate accounts for $50,000. LBHI offered those with class 3 claims of $50,000 or less the opportunity to sell those claims back to the estate for 26 cents on the dollar at the emergence from BK. I took that deal knowing that it would be years to see all distributions. Once those claims were bought back they were cancelled. If you accepted the deal you became a class 6a claimant.
It is all in the disclosure statement.
