I found these 2:
The service cost component of the net periodic postretirement benefit cost is
A. Included in the APBO but not in the EPBO.
B. Included in the EPBO but not the APBO.
C. Measured using implicit and explicit actuarial assumptions and present value techniques.
D. Defined as the portion of the EPBO attributed to employee service for a period.
Answer (D) is correct.
Service cost is defined as the actuarial present value of benefits attributed to services rendered by employees during the period. It is the portion of the EPBO attributed to service in the period and is not affected by the level of funding.
The interest cost component of the NPPBC is the
A. Product of the market-related value of plan assets and the expected long-term rate of return on plan assets.
B. Increase in the EPBO because of the passage of time.
C. Increase in the APBO because of the passage of time.
Answer (C) is correct.
Interest cost reflects the change in the APBO during the period resulting solely from the passage of time. It equals the APBO at the beginning of the period times the assumed discount rate used in determining the present value of future cash outflows currently expected to be required to satisfy the obligation.
D. Change in the APBO during the period.
