Pension service cost has one role in the employer's benefit accounting. Service cost is the actuarial present value of benefits attributed to employee service in the current period. It increases PBO and enters net periodic pension cost from the same supported actuarial schedule.

Apply it

Cedar Trail's $1.2 million service cost appears as an increase in PBO and a cost component. It is one amount with two linked destinations, not two expenses.

Common mistake

Do not assume that service cost is the cash paid for employee service. Service cost is the actuarial increase in the obligation from service during the period. That error would disconnect current employee service from the actuarial increase it creates in the obligation.

Keep the boundary clear

Accounting can trace and reconcile supplied service cost but cannot calculate participant benefits, choose an attribution method, or select actuarial assumptions.

Authority

Read ASC 715-30-35-6 for the pension service-cost component.
