Total Pension expense

What is the right formula for total pension expenses? schweser says it is employer contribution less (end funded status - beginning funded status) while as per Fitch it is reverse tht is change in funded status less employer contribution

it depends on whether you define funded status as assets less liabilities or liabilities less assets.

if we define it as assets less liabilities, then: change in funded status = employer contribution - TPPC

TPPC = employer contributions - (end funded status - start funded status) is what I’ve always used.

See this post for a very nice description of pension expense - this is what I use.
