Sir in same question while calculating sensitive anaysis for decomissioning cost its 122.2/.1571=777.8 from where did the figure .1571 came.Please clarify. Many thanks.
It is the discount factor for 33 years at 10%. (1/1.10)^33 = 0.043
Second question:
Because in this part they are looking at current price values, the real cost of capital is 1.1/1.04 – 1 = 5.7692% The discount factor for 33 years at 5.7692 is (1/1.057692)^33 = 0.1571
