A firm that manufactures freezer for delivery vans currently has excess capacity. The firm expects that it will exhaust its excess capacity in three years. At that time it will have to invest P2,500,000 to build new capacity. Suppose that the firm can accept additional work as a subcontractor for another company. By doing so, the firm will receive a net cash inflow of P150,000 immediately and in each of the next three years. However, the firm will have to begin expansion two years earlier than originally planned to bring new capacity on line. Assume a discount rate of 12%. a. What is the NPV if the firm accepts the subcontractor job? b. What is the minimum amount that should be received from the subcontractor job for the company to accept it?
