2. (25 points) Beckinridge Plastic Co plans to undertake one of the following two projects, say A and B, for this fiscal year. The cost of project A is $ 120,000 and the cost of B is also $120,000. The firm's cost of capital is 7% per year. After-tax cash flows are estimated to be $ 10,000 per year for 30 years for project A. After-tax cash flows for project B are expected to be $ 9,000 per year forever. (a). Please compute NPV and IRR for both projects. Which project should Beckinridge undertake? (b). Capital budgeting techniques are very sensitive to the choice of the cost of capital. At what interest rate would Beckinridge be indifferent between these two projects? That is, what is the interest rate at which NPV = NPVB? You must show your work and provide exact answer. Also, at this interest rate, what is the NPVA (or NPVB)? Please be precise. Don't forget that PV of an annuity is PV = PMT[1- 1/(1+i)"]/i and PV of a perpetuity is PV = PMT/i.
