Question:
Ting Young, the Production Manager at Mikocheni Minerals Cutting Technologies Ltd (MMCTL), purchased a cutting machine for the company last year. Six months after the purchase of the cutting machine, Ting learned about a new cutting machine that is more reliable than the machine that she purchased earlier. The following information is available for the two machines:
Category Old Machine New Machine
Acquisition Cost TZS 300,000,000 TZS 360,000,000
Remaining Life 4 Years 4 Years
Salvage Value Now TZS 100,000,000 ___
Salvage Value at the End of 4 Years TZS 4,000,000 TZS 6,000,000
Annual operating costs for the old machine are TZS 140,000,000/=. The new machine will decrease annual operating costs by TZS 60,000,000/=. These amounts do not include any charges for depreciation. MMCTL uses the straight-line depreciation method. These estimates of operating costs exclude rework costs. The new machine will also result in a reduction in the defect rate from the current 5% to 2.5%. All defective units are reworked at a cost of TZS 1,000/= per unit. The company, on average, produces 100,000 units annually.
