a) There are four rules regarding how net present value should be applied in practice. They relate to the identification of relevant cash flows, which elements to include, the treatment of inflation, and to how the impact of debt finance is treated.

[10 marks] b) A project requires an initial investment of 200,000 and expects to produce a cash flow before taxes of 120,000 per year for two years (cash flows will occur at t=1 and t=2 ). The company tax rate is 21 percent. The assets will depreciate using the following schedule: (Year 1, 33\%); (Year 2, 45\%); (Year 3, 15\%); (Year 4, 7\%). The company's tax situation is such that it can use all applicable tax shields. The opportunity cost of capital is twelve percent. Assume that the asset can sell for book value at the end of the project. Calculate the net present value of the project.
