Problem 5 (30 Points: Covey Company purchased a machine on January 1, 2014, by paying cash of $500,000. The machine has an estimated useful life of five years, is expected to produce 1,000,000 units, and has an estimated residual value of $50,000. Required: (A) Calculate depreciation expenses to the nearest whole dollar for the first two years of the machine's useful life under Straight-line depreciation method. (5 Points) (B) Calculate depreciation expense to the nearest whole dollar for the first two years of the machine's useful life under Double declining-balance method. (10 Points) (C) What is the book value of the machine after three years using the double declining-balance method? (5 Points) (D) What is the book value of the machinery after three years using the straight-line method? (5 Points) (E) If the machine was used to produce and sell 240,000 units in 2014, what would be the depreciation expense using the units-of-production method? (5 Points) A) Straight line method Annual depreciation expense= (Cost- Residual Value)/Useful life in number of years Annual depreciation expenses ($500,000-$50,000)/5 Annual depreciation expense= $90,000. Year 1= Annual Depreciation=$90,000 Year 2= Annual Depreciation=$90,000 B) Double declining rate=Straight line depreciation (cost-Residual value)*100=$90,000/$450000*100*2 Double declining rate=$90,000/$45000*100*2=40% Year 1= Cost 40%-$500000*40%-$200000 Year 2= Book value*40%=($500000-$200000)*40%=$120,000. C) Year 3 depreciation($500,000-$200,000-$120,000)-40%=$72,000 Book value at the end of year 3= Cost Accumulated Depreciation=$500,000-$200,000- $120,000-$72,000-$108,000. D) Book value at the end of year 3= Cost-(Annual Depreciation 3)S500,000- $270,000-$230,000
