Given that it's a legal issue, the assets that have been set aside in the pension, the trust assets, belong to the employees. They do not fall within the bankrupt estate, nor do any creditors have any exposure to that. The value of those pension assets is a function, in part, of the market. It's the same thing whether it's a bankrupt company or a solvent company. That's why a lot of companies, most companies, have a pension deficit.
The point is that there is nothing in this process that takes away the value from the pension plan. It cannot, because those assets do not belong to the company.
