(ARO) Probability of Yearly Loss (decimal):            Annualized Rate of Occurrence -- probability that a risk will occur in a particular year (AV) Asset Value ($):            Asset Value -- a monetary value assigned to an asset (based on actual cost or its replacement and labor costs, or lost revenue) (EF) Exposure Factor (% as a decimal):            Exposure Factor -- a proportion of an asset's value that is likely to be destroyed by a particular risk         (SLE) Single Loss Expectancy ($):            SLE = AV * EF   Single Loss Expectancy -- expected monetary loss every time a risk occurs (ALE) Annualized Loss Expectancy ($):            ALE = ARO * SLE   Annualized Loss Expectancy -- expected monetary loss that can be expected for an asset due to a risk over a 1-year period
