Answer:
Pension expense:
= Service cost + Interest on PBO - actual return
= 40,000 + (10% * 160,000) - 15,000
= $41,000
PBO at end of year:
= Beginning PBO+ Service cost + Interest on PBO - Benefits paid
= 160,000 + 40,000 + (10% * 160,000) - 20,000
= $196,000
Pension Assets at end of year:
= Beginning PBO + Return + Contribution - Benefits
= 160,000 + 15,000 + 30,000 - 20,000
= $185,000
