Exercise revision on capital budgeting cash flow A machine currently in use was originally purchased 2 years ago for $40,000. The machine is being depreciated under MACRS using a 5-year recovery period; it has 3 years of usable life remaining. The current machine can be sold today to net $42,000 after removal and cleanup costs. A new machine, using a 3-year MACRS recovery period, can be purchased at a price of $140,000. It requires $10,000 to install and has a 3-year usable life. If the new machine is acquired, the investment in accounts receivable will be expected to rise by $10,000, the inventory investment will increase by $25,000, and accounts payable will increase by $15,000. Profits before depreciation and taxes are expected to be $70,000 for each of the next 3 years with the old machine and to be $120,000 in the first year and $130,000 in the second and third years with the new machine. At the end of 3 years, the market value of the old machine will equal zero, but the new machine could be sold to net $35,000 before taxes. Both ordinary corporate income and capital gains are subject to a 40% tax. a. Determine the initial investment associated with the proposed replacement decision. b. Calculate the incremental operating cash inflows for years 1 to 4 associated with the proposed replacement. (Note: Only depreciation cash flows must be considered in year 4.) c. Calculate the terminal cash flow associated with the proposed replacement decision. (Note: This is at the end of year 3.) d. Depict on a time line the relevant cash flows found in parts a, b, and that are associated with the proposed replacement decision, assuming that it is terminated at the end of year 3
