Question

3 Net Present Value Part A 00 to construct and will last 5 years (it is con An ethanol processing facility costs $25,0 structed in year 0 and runs from year 1 through year 5). It produces 1000 barrels of ethanol per year and can charge a price of $10 per barrel. If the interest rate is 7%, what is the net present value of this facility? Part B A different ethanol processing facility costs $800,000 to construct but will instead last forever. Every year (starting the year after construction), it produces 10,000 barrels of ethanol and can charge a price of $4 per barrel. At what interest rate would an investor be indifferent between constructing the facility and simply keeping the money?

Explanation / Answer

A) n = 5 and r = 7%

NPV = -25000 + 1000 x 10/(1 + 7%) + .... + 10000/(1 + 7%)5

NPV = $ 16001.97

B) let the interest rate = r

Equate the net present value = 0

800000 = 10000 x 4/(1 + r) + 40000/(1 + r)2 + .......

800000 = 10000 x 4/r

r = 5%
