Question 6 (13 marks) (a) A machine was acquired on 1/1/2012 at $380,000. The Salvage value was estimated to be $20,000 with a useful life of 5 years. The management analyses the pattern of depreciation expense under 2 different depreciation methods. Compute the depreciation expense and accumulated depreciation under each of the following two methods over the 5-year period: straight-line method and double-declining- balance method. (b) Compare and contrast the income effect using the two depreciation methods computed in (a). (c) What is salvage value and explain how will it affect the disposal value of the plant asset on eventual sale? The industry practice is to estimate a zero-salvage and does this affect your argument here?
