4.3. Summary of Simulation model analysis

And now have a good look at the Table 4.11 and 4.12. it is possible to see that NPV and PI do not change dramatically, consequently the advantages of the third contract could not be preserved, but rules of IRR tell us to reject all three contract (11.35, 13, and 20.36 lower than 23.5171 and 25.2705), but it is not real situation. I have a doubt about result which IRR is showing us. I may be mistaken estimating the free-risk rate, may be something I wrong with market-rate, may be beta is not appropriate. There are lots of possibilities to make a mistake, that’s why I make conclusion that the easiest and the most reliable method of estimation the discount rate of contract is estimating the WACC of company and using it as discount rate.

4.4. Scenario analysis and calculation

Scenario Analysis, if the variables are interrelated, may help to consider some alternative plausible scenarios. Managers often find scenario analysis helpful. It allows them to look at different but consistent combinations of variables. Forecast generally prefers to give an estimation of discount rate under particular scenario than to give some optimistic or pessimistic estimation. Company tries to cope with problem of future estimation by examining the effect on the project of alternative plausible combinations of variables. In other words, they estimate the NPV for example as the project under different scenarios and compare these estimations with the base results. Scenario analysis can also be used to work out “best” and “worst” scenarios to establish a rage of possible future value. Then the annual standard deviation should be found to generate this range.

In my research it is possible to look through “optimistic” and “pessimistic” scenarios, because I take the calculations which exist as most probable scenario.

4.4.1. Discount rates that based on wacc

As you’ve seen in Table 4.13 there are results of calculations with WACC as discount rate (see the topic 4.2.1.) where the WACC is 0.1226.

Experts’ estimation Optimistic is 0.1226; Most Probable is 0.1338, and Pessimistic is 0.1499 (see the Appendix 9 Part 2)

I would like to present the result of calculation with WACC as discount rate in tables as the following:
