Exercise 251 Payback period computation; even cash flows Compute the payback period for each of these two separate investments (round the payback period to two decimals): a. b. P1 Exercise 252 Payback period computation; uneven cash flows A new operating system for an existing machine is expected to cost $250,000 and have a useful life of four years. The system yields an incremental aftertax income of $72,000 each year after deducting its straightline depreciation. The predicted salvage value of the system is $10,000. A machine costs $180,000, has a $12,000 salvage value, is expected to last eight years, and will generate an aftertax income of $39,000 per year after straightline depreciation. Walker Company is considering the purchase of an asset for $90,000. It is expected to produce the following net cash flows. The cash flows occur evenly throughout each year. Compute the payback period for this investment. Problem 251A Computation of payback period, accounting rate of return, and net present value Burtle Company is planning to add a new product to its line. To manufacture this product, the company needs to buy a new machine at a $488,000 cost with an expected fouryear life and a $15,200 salvage value. All sales are for cash, and all costs are out of pocket except for depreciation on the new machine. Additional information includes the following. P1 P2 P3 Check (4) 27.14% (5) $140,794 Required 1. Compute straightline depreciation for each year of this new machine's life. (Round depreciation amounts to the nearest dollar.) 2. Determine expected net income and net cash flow for each year of this machine's life. (Round answers to the nearest dollar.) 3. Compute this machine's payback period, assuming that cash flows occur evenly throughout each year. (Round the payback period to two decimals.) 4. Compute this machine's accounting rate of return, assuming that income is earned evenly throughout each year. (Round the percentage return to two decimals.) 5. Compute the net present value for this machine using a discount rate of 8% and assuming that cash flows occur at each yearend. (Hint: Salvage value is a cash inflow at the end of the asset's life. Round the net present value to the nearest dollar.)
