Eddison Inc. purchased a capital asset for $224,000 in 202. Management estimated that the asset would have an 8-year life with an estimated residual value of $17,000. Management depreciated assets using the straight-line method and recorded a full year's depreciation in the year of purchase. The tax rate is 20%. Assume that in 204, management was reviewing its policies relating to its capital asset accounts. Consider the following independent scenarios: Required: 1-a. Determine whether each case is a change in estimate, a change in policy, or an accounting error. 1-b. Determine whether each case is accounted for retrospectively or prospectively. 2. Calculate the 20X4 depreciation expense. 3. Provide a correcting entry for all Scenarios in 20X4. (show your work)
