Lecture: Discount Rates and Risk in Long Life Projects 

The presentation examines industry practice regarding the development and use of discount rates for Discounted Cash Flow (DCF) evaluations. It also examines the impact that discount rates have on project evaluations and raises questions about the use of risk adjusted discount rates (RADR) to assess risk in longlife projects. A simple approach is proposed for addressing both the time value of money and risk in DCF evaluations with respect to capital costs, operating costs, schedules, ramp-up, tonnes, grade and price.
