Problem: Buster Container Company is suffering declining sales of its principal product, nonbiodegradeable plastic cartons. The president, Dennis Harwood instructs his controller, Shelly McGlone, to lengthen asset lives to reduce depreciation expense. A processing line of automated plastic extruding equipment, purchased for 3.1 million in January 2012, 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. Dennis wants the estimated life changed to 12 years total, and the straight-line method continued. Shelly is hesitant to make the change, believing it is unethical to increase net income in this manner. Dennis says, Hey, the life is only an estimate, and i've heard that our competition uses a 12 year life on thier production equipment.
What is the effect of Dennis Harwood's proposed change on income before taxes in the year of change??
