What is the correct formula to calculate single loss expectancy?
It can be defined as the monetary value expected from the occurrence of a risk on an asset. It is mathematically expressed as follows: Single Loss Expectancy (SLE) = Asset Value (AV) * Exposure Factor (EF) where the Exposure Factor is represented in the impact of the risk over the asset, or percentage of asset lost.
How is annualized rate calculated?
The annualized rate is calculated by multiplying the change in rate of return in one month by 12 (or one quarter by four) to get the rate for the year. Annualized rate of return is computed on a time-weighted basis.
How do you calculate annualized performance?
