The annualized loss expectancy (ALE) method of risk analysis:

The annualized loss expectancy (ALE) method of risk analysis is a quantitative method that estimates the expected monetary loss that can result from a risk over a one year period. The ALE is calculated by multiplying the single loss expectancy (SLE), which is the monetary loss from a single occurrence of a risk, by the annualized rate of occurrence (ARO), which is the frequency of the risk occurring in a year. The ALE can be used in a cost-benefit analysis to compare the cost of implementing a control or a risk response with the expected benefit of reducing the loss. The ALE can help to justify the investment in risk management and to prioritize the risks based on their financial impact. The other options are not accurate descriptions of the ALE method of risk analysis, as they involve different aspects or methods of risk analysis. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 2, Section 2.3.2.1, pp. 60-61.
