Question

Goltra Clinic is considering investing in new heart-monitoring equipment. It has two options: Option A would have an initial lower cost but would require a significant expenditure for rebuilding after 4 years. Option B would require no rebuilding expenditure, but its maintenance costs would be higher. Since the Option B machine is of initial higher quality, it is expected to have a salvage value at the end of its useful life. The following estimates were made of the cash flows. The company?s cost of capital is 7%.

Compute the (1) net present value, (2) profitability index, and (3) internal rate of return for each option. (Hint: To solve for internal rate of return, experiment with alternative discount rates to arrive at a net present value of zero.)

Option A Option B Initial cost $170,000 $245,000 Annual cash inflows $72,100 $80,500 Annual cash outflows $29,000 $26,000 Cost to rebuild (end of year 4) $51,200 $0 Salvage value $0 $8,800 Estimated useful life 7 years 7 years
