Millat Tractor is considering the replacement of an existing machine. The new machine costs Rs.1.2 million and requires installation costs of Rs.150,000. The existing machine can be sold currently for Rs.185,000 before taxes. It is 2 years old, cost Rs.800,000 new, and has a Rs.384,000 book value and a remaining useful life of 5 years. It was being depreciated under MACRS using a 5-year recovery period and therefore has the final 4 years of depreciation remaining. If it is held for 5 more years, the machine's market value at the end of year 5 will be Rs.0. Over its 5-year life, the new machine should reduce operating costs by Rs.350,000 per year. The new machine will be depreciated under MACRS using a 5-year recovery period. The new machine can be sold for Rs.200,000 net of removal and cleanup costs at the end of 5 years. An increased investment in net working capital of Rs.25,000 will be needed to support operations if the new machine is acquired. Assume that the firm has adequate operating income against which to deduct any loss experienced on the sale of the existing machine. The firm has a 9% cost of capital and is subject to a 40% tax rate.

a. Develop the relevant cash flows needed to analyze the proposed replacement.

b. Determine the net present value (NPV) of the proposal.

c. Determine the internal rate of return (IRR) of the proposal.

d. Make a recommendation to accept or reject the replacement proposal, and justify your answer.

e. What is the highest cost of capital that the firm could have and still accept the proposal? Explain.
