I think there is some bad info being posted here about the PBGC. They have a max rate they will guarantee per month and it depends on your age. Also, it appears that a surviving spouse would only receive 50% of the pension, GE's plan let's you chose between 100 to 50%.
Bottom line for many who have been with GE for a long time, it is likely less than what you expected or planned for. https://www.pbgc.gov/wr/benefits/guaranteed-benefits/maximum-guarantee
