Dieker Container Company is suffering declining sales of its principal product, nonbiode-gradeable plastic cartons. The president, Edward Mohling, instructs his controller, Betty Fetters, to lengthen asset lives to reduce depreciation expense. A processing line of automated plastic extruding equipment, purchased for $3.1 million in January 2014, 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. Edward wants the estimated life changed to 12 years total, and the straight-line method continued. Betty is hesitant to make the change, believing it is unethical to increase net income in this manner. Edward says, Hey, the life is only an estimate, and Ive heard that our competition uses a 12-year life on their production equipment. Instructions (a) Who are the stakeholders in this situation? (b) Is the change in asset life unethical, or is it simply a good business practice by an astute president? (c) What is the effect of Edward Mohlings proposed change on income before taxes in the year of change?
