Speculation is that it’s beneficial to IBM because the money will be under their management rather than Fidelity’s. What exactly they’re allowed to do with that money, I’m unsure.
I'm not sure if this is legally a pension, if not assume it is worth nothing. If it is the US government backs it and so if you work for IBM for 30 it is a great deal, pensions are defined income so you don't have to worry about if you will live to 66 or 120. (If like most you switch jobs it is terrible)

401ks are a separate thing entirely. Generally they don’t let you invest in individual stocks at all.
