$ 376153 is depreciation on the building for 2018.
Explanation:
Given data:
Original cost = $13.1 million
Residual value = $2.1 million
Useful life = 20 -year
Depreciation on the building for 2016 = [tex]=\frac{\text {original cost-residual value}}{\text { Useful life }}[/tex]
By substituting the given values, we get,
[tex]=\frac{(\$ 13.1 \text { million }-\$ 2.1\text { million) } }{20 \text { years }}=\frac{11.1 \text { million }}{20 \text { years }}[/tex] = 5500000
Depreciation for 2016 $5500000
Depreciation for 2017 $5500000
Depreciation at Dec 31, 2017 $ 5500000
In 2018, the estimates of useful life and residual value were changed to 15 years and $610000, but 2 yrs have already passed, so there're 13 more yrs to go.
Depreciation on the building for 2018,
[tex]=\frac{\text { book value at the end of } 2016-\text {residual value}}{\text { useful life }}[/tex]
= [tex]=\frac{\$ 5500000-\$ 610000}{13}=\frac{4890000}{13}=\$ 376153[/tex]
