You have a frozen plan? Mine was terminated. My PBGC benefit is frozen as it does not have any COLA from the time the plan was terminated. Is that what you mean?
The PBGC annuitized value increases by $2k per month at age 65, but that is not an increase in the overall value of the plan. So how does that cover a 20 percent deficit in your calculations? It definitely wont cover my 60 percent deficit in expected retirement benefits. HUH!!??
