Answer:
11.66 million
Step-by-step explanation:
Annual Amortization Expense:
= Cost of acquiring at the beginning of the year ÷ 9-year life
= $42 million ÷ 9
= $4.67 million per year
Year 2021 Amortization Expense 4 Years:
= Annual Amortization Expense × 4
= $4.67 per year × 4 years
= $18.68 million
Unamortized Cost:
= Cost of acquiring at the beginning of the year - Amortization Expense 4 Years
= $42 million - $18.68 million
= $23.32 million
Patent amortization expense in 2021:
= Unamortized Cost ÷ 2
= $23.32 ÷ 2
= 11.66 million
