Value at risk is a measure used to estimate the probability that losses exceed a threshold over what time horizon?

• A. Two years
• B. Ten years
• C. One year
• D. Five years

Answer: (C)

Value at risk defines the maximum loss expected to be exceeded with a specified probability over a defined period. In this context, the standard horizon used for VaR is one year. So, VaR at a chosen confidence level over one year indicates the loss threshold that should not be exceeded with that probability during the coming year. The one-year horizon aligns with annual planning, reserves, and reporting, making the measure interpretable and practically useful. Longer horizons can be used, but they require additional modeling assumptions about how losses evolve over time, which is why, for this topic, one year is the typical focus.
