Risk And Control - 15% Flashcards
What is the difference between risk and uncertainty?
Risk - quantifiable - possible outcomes have associated probabilities, thus allowing the use of mathematical techniques.
Uncertainty - unquantifiable- outcomes cannot be mathematically modelled
How do we deal with risk and uncertainty in investment appraisal decisions?
Adding a risk premium
Payback period
Expected values
Sensitivity analysis
Probability distributions
Monte carlo simulation
How do we calculate sensitivity margin?
NPV / PV of flow under consideration
What are the strengths of sensitivity analysis?
It is simple
It helps management make more informed decisions
Identifies critical estimates
What are the Weaknesses of sensitivity analysis?
Assumes that changes to variables can be made independently
Does not look at how likely it is the variable will change
Does not give a definitive decision
What is expected value?
Summarises all the different possible outcomes by calculating a single weighted average
What are the advantages of expected value?
Takes risk into account
Easier decisions
Simple
What are the disadvantages of EV?
Subjective
Has little meaning for a one off project
Gives a risk neutral decision
May not correspond to any actual possible outcomes
What is a monte carlo simulation?
A computerised system that extends sensitivity analysis.
Modelling technique that shows the effect of more that one variable changing at the same time.
Uses random numbers an probability statistics.
What is value at risk?
Measure of how the market value of an asset or of a portfolio of assets is likely yo decrease over a certain time.
What does a square represent on a decision tree?
Decision point
What does a circle represent of a decision tree?
Chance outcome point
What is a stress test?
A way of analysing a business to consider how well it could cope in difficult conditions.
What are the 4 key areas of stress testing?
Prioritisation
Measurement
Productivity
Flexibility
Why would we incur risk?
Gain competitive advantage
Increase financial return
