Answer:
The appropriate adjusting entry for patent amortization in 2021 to reflect the revised estimate would be as follows:
Amortization Expense Dr. 3 million
Patent Cr. 3 million
Step-by-step explanation:
In order to Prepare the appropriate adjusting entry for patent amortization in 2021 to reflect the revised estimate we would have to make the following calculations:
Calculation after the Change:
Original Cost =$10.8 million
Annual Amortization (Old) =$10.8 million/9 = $1.2 million
Amortization till Date (2017 - 2021) = 1.2*4 = 4.8 million
Unamortized Value = 10.8 - 4.8 = 6 million
Remaining Life = 6 - 4 = 2 Years
New Amortization = Unamortized Value/Remaining Life = 6/2 = 3 million
Therefore, the appropriate adjusting entry for patent amortization in 2021 to reflect the revised estimate would be as follows:
Amortization Expense Dr. 3 million
Patent Cr. 3 million
