It's actually a concession offset. An offset against concessions you didn't have to make, since you weren't working for Delta at the time. One of the items being offset, was the loss of a pension. Don't be surprised if you don't get too much sympathy from the people who had to purchase the PS WITH concessions.

Doesn't mean you're not entitled to discuss what the combined group should do with common equities, including the PS, going forward. If you want to trade the PS, knock yourself out: you're entitled. But spare us the disparaging labels, and the attendant insult.
