One is to expand its production capacity. The estimated cost of the new equipment is OMR 250 million and has a life of 10 years. Forecasts of cash inflows would be OMR45 million per annum for the first 3 years, OMR 68 million from 4 to 8 years and OMR 30 million for the last 2 years. The plant can be sold for 55 million at the end of its economic life. The second proposal is to replace one of the old machines in Sohar to reduce the cost of operations. The new machine will cost OMR 50 million. The life of the machine is 10 years without any salvage value at the end. The replacement will result in saving of OMR25 million per year. The company can borrow funds from the National Bank of Oman at an interest rate of 8% per annum. It will be required to pay equal annual payments of interest and principal. The CEO of the company was thinking of paying a single amount after 10 years (instead of annual installments). Discussion questions (a) Should the company expand its capacity? Show the computation of NPV. (b) Should the company replace the existing machine? (c) What is the annual installment of the bank loan? (d) What is the rate of return on her investment?
