Single Loss Expectancy is a term related to Risk Management and Risk Assessment. It can be defined as the monetary value expected from the occurrence of a risk on an asset.
It is mathematically expressed as:
Where the Exposure Factor is represented in the impact of the risk over the asset, or percentage of asset lost. As an example, if the Asset Value is reduced two thirds, the exposure factor value is .66. If the asset is completely lost, the Exposure Factor is 1.0. The result is a monetary value in the same unit as the Single Loss Expectancy is expressed (euros, dollars, yens, etc.): Exposure Factor is the subjective, potential percentage of loss to a specific asset if a specific threat is realized. The exposure factor (EF) is a subjective value that the person assessing risk must define.
