Chapter 5: Introduction to risk management Flashcards
(48 cards)
What is risk?
Risk is ‘the possible variation in an outcome what is expected to happen’.
What is the COSO definition of risk?
Risk is ‘the possibility that an event will occur and adversely affect the achievement of objectives.
What is the COSO definition of opportunity?
Opportunity is ‘the possibility than an event will occur and positively affect the achievement of objectives.
What is uncertainty?
Uncertainty is the ‘inability to predict outcomes because of a lack of information’ (not the same as risk)!
What are the three attitudes to risk?
Risk averse attitude
Risk neutral attitude
Risk seeker attitude
What is a risk averse attitude?
An investment would be chosen if it has more certainty but possibly a lower return than an alternative less certain, potentially higher return investment.
What is a risk neutral attitude?
An investment would be chosen according to its expected return, irrespective of risk.
What is a risk seeker attitude?
An investment would be chosen on the basis of it offering higher levels of risk, even if its expected return is lower than an alternative no-risk investment with a higher expected return.
What are the three different classifications of risk?
Business risk
Financial risk
Operational risk
What are some examples of sustainability and climate related risks?
Damage to supply chain and property
Impact on reputation
Not meeting regulations regarding emissions and climate
What categories can event risk be broken down into?
Disaster - catastrophe occurs such as a fire, flood etc.
Regulatory - new laws or regs are introduced
Reputation - risk of damage to the business’s reputation
Systematic - failure by a participant in the business’s supply chain
What is risk measurement?
Risk measurement identifies the probability of the risk occurring and quantifies the resultant impact and calculating the amount of the potential loss using expected values for gross risk.
What are descriptive statistics?
Descriptive statistics are used to describe a set of data.
What is descriptive analysis?
Descriptive analysis gives you an idea of the distribution of the data, helps you detect anomalies and enables you to identify relationships between variables.
What is a measure of central tendency?
Measures of central tendency i.e. mean, mode, median and expected value; are used to attempt to describe the usual or average value in a population. If this is related to risk - the average tells what we should expect from a set of data.
What is the deviation?
The deviation is a measure of how far away from the mean a value is in a data set.
What is the variance?
The variance is the average of the squared deviations of all the values in a data set.
What is the standard deviation?
The standard deviation is the square root of the variance
What is the coefficient of variation?
The coefficient of variation is the standard deviation divided by the mean
What is a frequency distribution?
A frequency distribution is where data is in groups e.g. no. of people that fall within the income brackets.
What is a normal distribution?
The data is symmetrical and peaks in the centre.
It is a bell curve
The mean is shown in the y-axis
50% of the values will be below the mean and 50% above
The total area under the curve equals 1
The standard deviation shows how far the value spread out from the mean
What are the general percentage rules in a normal distribution?
34% of values lie between mean and 1 standard deviation
47.5% of values lie between the mean and two standard deviations
49.9% of values lie between the mean and three standard deviations
What is a negative skew?
Left (negatively) skewed - values are concentrated on the right hand side so the graph would have a long left tail.
The mode is often the highest point, with the median and mean to the left of the mode.
What is a positive skew?
Right (positively) skewed - values are concentrated on the left hand side so the graph would have a long right tail.
The mode is often the highest point, with the median and mean to the right of the mode.
