What does ALE stand for in risk management?

• A. Annualized Loss Expectancy
• B. Average Loss Expectancy
• C. Alpha Loss Estimation
• D. Aggregate Loss Expentancy

Answer: (A)

In risk management, ALE stands for Annualized Loss Expectancy. It represents the expected monetary loss from a risk on a yearly basis. You get ALE by multiplying how much you would lose in a single incident (Single Loss Expectancy, SLE) by how often such incidents are expected to occur in a year (Annualized Rate of Occurrence, ARO). So ALE = SLE × ARO. For example, if an asset is worth $100,000 and the potential loss per incident is 40% of its value (SLE = $40,000), and such incidents are expected to happen 0.5 times per year (ARO = 0.5), the ALE would be $20,000 per year. This helps compare the expected annual loss to the cost of controls or mitigations to decide if and where to invest in security. The other options don’t reflect standard risk-management terminology: they’re either inaccurate or nonstandard terms.
