1. On January 1, 2005, Wintz Corporation acquired machinery at a cost of $600,000. Wintz adopted the straight-line method of depreciation for this machine and had been recording depreciation over an estimated life of ten years, with no residual value. At the beginning of 2008, a decision was made to change to the double-declining balance method of depreciation for this machine. a. Assuming a 30% tax rate, what is the cumulative effect of this accounting change on beginning retained earnings? b. What amount should Wintz record as depreciation expense for 2008? Please show the work. Thank you
