Answer: $27,000
Step-by-step explanation:
Amortization of prior cost = (No. of employees / Total number of years left) * Unamortized prior service cost
Total number of years left:
2 employees are each expected to have 9 years remaining = 2 * 9
= 18 years
3 employees are each expected to have 6 years remaining = 3 * 6
= 18 years
4 employees are each expected to have 1 year remaining = 4 * 1
= 4 years
Total number of years = 18 + 18 + 4
= 40 years
Amortization of prior cost = (9 / 40) * 120,000
= $27,000
