george2006 The interest cost for pension plan is based on begining balance of the PBO, not ABO. Is this correct that other post-retirement benefit plan interest cost is based on ABO, not expected BO?
ssradja i thought the interest cost = PBO * discount rate. here the formula is ABO * discount rate. anybody?
creativemny This question is about the Post-retirement Benefit Obligation which is different then Pension Obligation. APBO is the only measure (there is no PPBO) because companies rarely fund these.
ngeorge yes, this question is for a post-retirement medical plan--not a pension plan.
