Pension Expense (both GAAP & IFRS) for the Income Statement

Pension Expense = Increase in the DBO/PBO during the accounting period.

Five Components of Company Pension Expense

1. Current Service Cost = Amount by which a company’s defined benefit obligation increases as a result of employee service during the accounting period.  The current service cost is fully and immediately recognized for the accounting period.
2. Interest Cost (same as the discount rate discussed later) = Amount by which a company’s existing defined benefit obligation increases as a result of the passage of time.  The interest cost is fully and immediately recognized for the accounting period.
3. Return on Plan Assets = Amount of returns generated by plan assets during the accounting period.  Typically, companies apply EXPECTED return on plan assets when calculating pension expense.  Long-term expected return will better reflect the plan’s investment strategy and reduce year to year volatility in the pension expense.  The use of expected returns is allowed by GAAP and IFRS.  Since this is an asset return, the return on plan assets component acts as a contra expense, offsetting other costs.
4. Amortization of Past Service Cost = The difference in the DBO after a plan amendment has been adopted and the DBO before the plan amendment.  The plan amendment could reduce costs, creating a benefit that reduces the pension expense.
