Answer:
patent amortization expense per year = $500,000 per year
Step-by-step explanation:
patent amortization expense per year = depreciable value / useful life of the intangible asset
- depreciable value = purchase cost - salvage value = $3,000,000 - $500,000 = $2,500,000
- useful life of the patent = 5 years (the legal life is different than the useful life)
patent amortization expense per year = $2,500,000 / 5 years = $500,000 per year
