I'm going to speculate that will happen at the same time of the next distribution. I didn't read that any show-stoppers had emerged to making this change so if it still has the green light, might as well do it when doing another transaction. It's going to be a complex security to value that's for sure. Might be a good speculative security that could be picked up cheap right after it starts trading as I'm sure many people will just dump it. .
You will get GUC trust units if it happens. You will get one unit for each $1,000 of debt that you hold.The current value of these units is between $20 and $110 depending on furture distribution. There is the $1.5B term loan and $5B in disputed claims still outstanding.
