• In finance, a distinction is made between risk and uncertainty.
• In finance, risk is measured by the dispersion around the mean value of the rate of return, the cost of borrowing, the value of assets and liabilities, etc.

Value at Risk
• VAR is a new approach to risk measurement and management.
• Over a given period of time with a given probability, how much money might be lost on a certain position?

• Measurement unit (e.g. AUD)• Time horizon (one day, one week,
etc.)• Probability (1-5%)
