IDK about your situation but pensions are contributed by the co as a % based on your annual salary (higher salary the more the co puts in)--' not every rep, manager, HQ or even pay grade is the same Pension.
Also Pfizer had a backend pension formula in that they contributed a smaller % in early yrs and larger % later year.
Last 10yrs---Year 20-30 the Pension grows 3-4x than the first 20. It is one of the formulas Pfizer had always used because the company is playing the odds most employees dont stay past 15-20yrs.
In my case, I am at 25yrs and 48yrs old. Legacy Pharmacia and if I took early retirement today with the 0% rates my Pension Lump Sum is showing 1.2million. (It is frozen of course & can only go down w higher rates-- being frozen it has grown 350k in 2yrs since 2018 w Feds lowering rates).
Several reps in my Oncology district have taken early retirement with a 1.5-2mil Pension.
Your situation might not be that much or it could be more, IDK but for a 25-30yr employee the Pension are over 1mil unless you didnt make a lot or salary & bonus in your career up until the time they froze it in 2012ish.
(Sad thing prior to freezing it, my pension projections at 65 was going to be close to 3mil but i have been in HQ & operations with high salary being a rep the past 10yrs.
