Actually the IAM has stated and the Company has corroborated it that they are willing to cut loose from the IAMNPF but the Company has to pay the “Withdrawal Liability Fee” which is something they agreed to when they first entered in to the fund.
That fee has grown to be pretty exorbitant but according to the PBGC Website they can make arrangements with the funds Trustees to pay it off over a 20 year term if mutually agreed to.
Remember that the Withdrawal Liability Fee is a Fee that protects the benefits you already earned so you can know they’re safe when you retire and on through.
Unfortunately with the latest bit of news I can absolutely understand you not wanting to remain in the fund. But if the Company doesn’t want to make that Balloon payment then the Company can’t get out from under its responsibilities and you will continue on.
That “could” ultimately mean you’re offered a formula like exists at UAL where they get the IAMNPF plus a 3% contribution and I also suspect new employees will only get the 401k?
