Question

You are is considering replacing a five-year-old machine that originally cost $50,000. It was being depreciated using straight-line to an expected salvage value of zero over its original 10-year life and could now be sold for $40,000. The replacement machine would cost $190,000 and have a five-year expected life. It would be depreciated using the MACRS 5-year class life. The actual expected salvage value of this machine after five years is $20,000. The new machine is expected to operate much more efficiently, saving $6,000 per year in energy costs. In addition, it will eliminate one salaried position saving another $54,000 annually. The firm’s marginal tax rate is 35% and the WACC is 7.5%.

a.   Set up an operating cash flow statement, and calculate the payback, discounted payback, NPV, IRR, and MIRR of the replacement project. Should the project be accepted?

Answer 1

The final answers are mentioned here. Detailed workings follow after the answers.

Payback period (years)

2.92

Discounted payback period (years)	4.51
NPV	$ 51,696
IRR	19.56%
MIRR	13.86%

Yes, the project should be accepted, as NPV is positive, IRR and MIRR > WACC and payback period is < life of the project
