I have already identified the risks using reference materials which I got from this forum. Now I am working on opportunities and Risks assessment but I got a challenge on computing the numbers for the impacts as I don't understand how the numbers were obtained in the reference document, please see the attachment below and help me how to interpret this, tomorrow morning I have a presentation to top management and real stucked here!
