Answer:
$714,000
Step-by-step explanation:
Amortization is the systematic allocation of the cost of an intangible asset to the income statement. While depreciation happens to a tangible asset, amortization happens to an intangible asset such as patent, trademark etc.
Mathematically,
Amortization
= Cost of asset / estimated useful life
= $1,190,000/10
= $119,000
At the start of 2020,
Carrying amount of patent
= $1,190,000 - 2($119,000)
= $952,000
Annual amortization from then, given that economic benefits of the patent would not last longer than 6 years from the date of acquisition (hence 4 years remaining)
= $952,000/4
= $238,000
Carrying amount reported in the balance sheet for the patent, net of accumulated amortization, at December 31, 2020
= $952,000 - $238,000
= $714,000
