Answer:
$1,152,600.00
Explanation:
Given
Cost of purchase = $1,680,875
Initial useful life = 15 years
Yearly amortization expense = $1,680,875/15
= $112,058.33
Between January 1, 2016 and 2018, the amount amortized
= $112,058.33 × 3
= $336,175.00
Net book value as at the beginning of 2019 = $1,680,875 - $336,175.00
= $ 1,344,700.00
Since during 2019, Pharoah determined that the economic benefits of the patent would not last longer than 10 years from the date of acquisition, it means the patent can only be amortized for 7 more years (10 - 3).
Therefore amortization charge for 2019
= $1,344,700.00/7
= $192,100
Net book value of patent at 31 December 2019 (net of accumulated amortization)
= $1,344,700.00 - $192,100.00
= $1,152,600.00
