Explanation:
Calculation for What amount should be reported for patent amortization expense for 2018
First is to calculate the Amortization amount
Amortization=$600,000-[($600,000/10 years)x(4/3)
Amortization=$600,000-$80,000
Amortization=$520,000
Now let calculate amount that should be reported for patent amortization expense for 2018
2018 Patent amortization expense=($520,000+$120,000)/4years
2018 Patent amortization expense=($520,000+$120,000)/4years=90,000
2018 Patent amortization expense=$640,000/4years
2018 Patent amortization expense=$160,000
Therefore What amount should be reported for patent amortization expense for 2018 is $160,000
