Final answer:
Deferred compensation is not a component of pension expense. Three components of pension expense are service cost, interest cost, and prior service cost amortization.
Step-by-step explanation:
The component of pension expense that would not be included is deferred compensation.
Pension expense is the cost of providing a pension plan to employees. The three components of pension expense are:
- Service cost: The current cost of providing pension benefits to employees for their services rendered during the period.
- Interest cost: The interest on the projected benefit obligation that accrues for the period.
- Prior service cost amortization: The recognition of costs related to making changes to the pension benefits for past services rendered by employees.
The return on assets is not a component of pension expense, but rather the earnings generated from the investments made by the pension plan.
