Prior to the IAM pension plan, fleet was on a 401k where the company had to pay in major $$. After the IAM pension plan went in, the company pension contribution to fleet retirement went down considerably. The concession was valued in the millions.
With regards to starting at 0 for the multiplier, IAM did not publish that fact in the term sheet. You had to wheedle it out of them.
With regards to whatever the multiplier currently is, the plan can reduce it as needed if they get in financial difficulty.
FWIW, I am a big fan of defined benefit plans (like the IAM) over defined contribution (401k) plans. The problem is, by law, the plans do not have to be funded to an actuarially sound basis.
Going forward, I'm wary of both plans, and would pick one over the other only after I had all the facts.
