The document discusses various techniques for risk analysis in project finance, including sensitivity analysis, scenario analysis, break-even analysis, and simulation analysis. It defines key risk analysis terms and provides examples of calculating expected net present value and standard deviation of NPV using the Hiller model under both uncorrelated and perfectly correlated cash flows. Simulation analysis involves modeling the relationship between variable factors and NPV, specifying probability distributions, running simulations to obtain multiple NPV outcomes, and analyzing the results. Project selection under risk may involve judgmental evaluation, payback period requirements, or risk-adjusted discount rates.
2. Risk Analysis
▪ Risk is inherent in almost every business decision
▪ Risk refers to variability
▪ Capital budgeting decision involves cost and benefits over a long period of time
▪ Financial analysis has two phases
▪ feasibility analysis
▪ Risk analysis
▪ Sources of Risk
▪ Project Specific Risk: factors specific to project like quality, production
▪ Corporate Risk: action of competitors
▪ Industry specific Risk: technological developments and regulatory charges
▪ Market risk: Changes in microeconomic factors have impact project
▪ International risk: in case of foreign projects or political risk

Range : Range of variance is difference of maximum and minimum value
Mean or average ҧ𝑥 = 𝐸 𝑥 = σ𝑖 𝑝𝑖 𝑥𝑖
Standard deviation : standard deviation (𝜎 ) is defined as 𝜎 = 𝐸 𝑥 − ҧ𝑥 2 = σ𝑖 𝑝𝑖 𝑥 − ҧ𝑥 2
Coefficient of Variation: standard deviation (𝜎 ) is not adjusted for scale. Coefficient of
variation is adjusted for scale and is defined as 𝐶𝑉 =
𝜎
𝐸𝑥𝑝𝑒𝑐𝑡𝑒𝑑 𝑀𝑒𝑎𝑛 𝑣𝑎𝑙𝑢𝑒
Semi Variance: since investors are concerned with negative variations only so computing
variance with only negative errors (outcome less than mean) gives semi variance
standard deviation (𝜎 ) is defined as
𝑠𝑒𝑚𝑖 𝑠𝑡𝑎𝑛𝑑𝑎𝑟𝑑 𝑑𝑒𝑣𝑖𝑎𝑡𝑖𝑜𝑛 = 𝐸 𝑥 − ҧ𝑥 2 𝑓𝑜𝑟 𝑜𝑛𝑙𝑦 𝑣𝑎𝑙𝑢𝑒𝑠 𝑜𝑓 𝑥 < ҧ𝑥

6. Measures of Risk
19-04-2018 BCH 505 Project Finance by Dr Naim R Kidwai 6
• Standard deviation is most commonly employed as measure of risk in finance.
• For computing mean and dispersion variables, probability distribution is required,
• If sufficient records for similar ventures are available, probability distribution is quite
‘objective,
• If sufficient records are not available, probability distribution is quite ‘subjective’,
Prospective on risk
There are three perspectives of the risk
• Stand alone risk: risk of the project when viewed in isolation
• Firm risk or Corporate risk: contribution of a project to the risk of the firm
• Systematic risk or market risk: risk of a project from view point of diversified investor
7. Sensitivity analysis
19-04-2018 BCH 505 Project Finance by Dr Naim R Kidwai 7
Sensitivity analysis is ‘what if’ analysis
NPV = -20000+4000 x PVIFA
= -20000+4000 x 5.65
= 2600 K
Cash flows depends on various factors and can
vary widely.
So optimistic and pessimistic estimates for
variables defined and NPV calculated

8. Sensitivity analysis
19-04-2018 BCH 505 Project Finance by Dr Naim R Kidwai 8
• NPV calculated by varying one variable at a time
• NPV is more sensitive to sales and least sensitive to fixed cost. For more sensitive
variable, it may be explored how variability of the factor can be contained.
• In real situation, many variable may change at a time so interpretation of results is
subjective

9. Scenario analysis
19-04-2018 BCH 505 Project Finance by Dr Naim R Kidwai 9
• Scenario analysis is beneficial when
various scenarios are well defined. It
considers several variable at a time
• More variable are required to be
estimated
• Normally scenarios are not discretely
defined

• It tells what is minimum value of key variables/
revenues so that project does not ‘lose money’
• Variable cost to sales ratio= 12/18= 0.667
• Contribution to margin ratio =0.333
• Accounting break even=

• At accounting break even project gives zero %

11. Financial Break-Even analysis
19-04-2018 BCH 505 Project Finance by Dr Naim R Kidwai 11
• Focus is on NPV and not on accounting profit
Variable cost =0.667 x sales
Contribution = 0.333 x sales
Fixed cost = 1000
Depreciation =2000
PBT= 0.333 x sales-3000
Tax= 0.333 x (0.333 x sales-3000)=0.111 x sales-1000
PAT= 0.667 x (0.333 x sales-3000)=0.222 x sales-2000
Cash flows= PAT+ depreciation= 0.222 x sales
PV of cash flows= Cash flows x PVIFA= 1.255 x sales
Breakeven NPV = 20000- 1.255 x sales= 0
so Breakeven sales= 15936 K

14. Simulation Analysis
19-04-2018 BCH 505 Project Finance by Dr Naim R Kidwai 14
• Sensitivity of criterion of merit (NPV IRR, ROI etc.) may not be adequate for decision making
• Likelihood of occurrence of circumstances (probability profile) can be obtained by
simulation
• The steps in simulation analysis are (criterion of merit is NPV)
1. Model the project : how criterion of merit is related to variables
• Parameter variables : input variables given by decision maker held constant in
simulation
• Exogenous variable: which are random in nature and can not be controlled
2. Specify the value of parameters and probability distribution of exogenous variables
3. Select a value randomly from probability distribution of exogenous variables.
4. Determine NPV
5. Repeat steps 2 to 4 a number of times to get large number of simulated NPV’s
6. Plot the frequency distribution of NPV
15. Project selection under risk
19-04-2018 BCH 505 Project Finance by Dr Naim R Kidwai 15
• Judgemental Evaluation: Accept or reject the project based on the risk and return
characteristics without any formal method for incorporating risk in decision making
• Payback period requirement: payback period requirement is applied to control risk.
• Risk adjusted discount method:
• If the risk of the project is equal to risk of existing investment, discount rate is
average cost of capital
• If the risk of the project is greater than risk of existing investment, discount rate is
higher than average cost of capital
