I'm not aware of any ordinary scenario in which estimated insurance or pension funding obligations are included in compensation figures.
That's because private companies
don't have _estimated_ pension funding obligations. I'm not aware of any private employer in the US which makes job offers that include a defined benefit retirement plan.
They either do some specific % 401(k) match, or they don't. In either case, the % is known and you factor it in as part of your total compensation when you compare employers.
For most private employers, the % they will contribute to your pension is zero or a single digit percentage.
Neither is directly realizable by the employee
It's realized after retirement, as I said earlier. I don't know whether you genuinely believe that money received after retirement doesn't count, but I think I'll stop repeating myself now :)
