Answer:
$14.44 million
Step-by-step explanation:
The computation of Amortization Expense 4 Years is shown below:-
Annual Amortization Expense = Beginning cost ÷ Life year
= $52 million ÷ 9
= $5.78 million
Amortization Expense 4 Years = Annual Amortization Expense × 4 years
= $5.78 million × 4
= $23.12 million
So,
Unamortized Cost = Beginning cost - Amortization Expense 4 Years
= $52 million - $23.12 million
= $28.88 million
Year 2018 Amortization Expense 4 Years = Unamortized Cost ÷ Estimated remaining life
= $28.88 million ÷ 2
= $14.44 million
So, for computing the Amortization Expense 4 Years we simply applied the above formula.
