Ethics Case Turner Container Company is suffering declining sales of its principal product, nonbio- deable plastic cartons. The president, Robert Griffin, instructs his controller, Alexis Landrum, to Cathen asset lives to reduce depreciation expense. A processing line of automated plastic extruding quipment, purchased for $3.5 million in January 2017, was originally estimated to have a useful life! of 8 years and a salvage value of $300,000. Depreciation has been recorded for 2 years on that basis. Robert wants the estimated life changed to 12 years total, and the straight-line method continued. Alexis is hesitant to make the change, believing it is unethical to increase net income in this manner. Robert says, "Hey, the life is only an estimate, and I've heard that our competition uses a 12-year life on their production equipment
