- Definition

The amount of expense (income) resulting from past service cost. Past service cost is the change in the present value of the defined benefit obligation for employee service in prior periods, resulting from a plan amendment (the introduction or withdrawal of, or changes to, a defined benefit plan) or a curtailment (a significant reduction by the entity in the number of employees covered by a plan). [Refer: Post-employment benefit expense in profit or loss, defined benefit plans; Defined benefit plans [domain]] [Contrast: Increase (decrease) in net defined benefit liability (asset) resulting from past service cost]
