As I recall, the IRS disallowed any "overfunding" of pension plans as that was deemed to be the hiding of profits. Maybe someone with more knowledge of these matters will clarify.
Indeed, it would be instructive to hear from someone more knowledgeable than I on this. Which wouldn't take much.
I am not up to date at all on their current pension liability situation. I *think* I am fairly accurate on the severity of their underfunding in the 80s. Past that I have not kept up. I would be surprised to find that there is currently any kind of surplus in the funding for pensions.
Anyone out there have some resources on this info?
