You have been asked to calculate the annualized loss expectancy (ALE) for the following variables:
 Single loss expectancy = $25
 Exposure factor = .9
 Annualized rate of occurrence = .4
 Residual risk = $30
 Which of the following is the resulting ALE?
 A. $9.00
 B. $22.50
 C. $10.00
 D. $14.27
Solution
C. $25 × .4 = $10, or Single loss expectancy (SLE) × Annualized rate of occurrence (ARO) = Annualized loss expectancy (ALE).
