Answer:
The amortization expense = $520,000/8 years = $65,000
Step-by-step explanation:
To determine the Amortization expense, First we need to understand General Accepted Accounting Principles (GAAP) on Intangible Assets.
The principle is that the cost of a successful legal defense of a patent infringement or any other similar intangible asset should be capitalized or become part of the book value of the intangible asset.
As such, there is a need to recompute the book value of the asset as follows
$480,000 (unamortized balance) + $40,000 (cost of successful defense of the patent against infringement)
= $530,000.
The useful remaining is 8 years (year 1 and 2 gone and case occurred in years 3)
The amortization expense = $520,000/8 years = $65,000
