=+2. A firm has two investment opportunities, each costing £100,000 and each having the expected net cash flows shown in the table below. While the cost of each project is certain, the cash-flow projections for project B are more uncertain than those for A because of additional inherent risks. Those shown in both cases can be assumed to be maxima. It has therefore been suggested that while the company’s cost of capital is of the order of 10 per cent, B might usefully be discounted at 15 per cent.
