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.

Famous quotes containing the words single, loss and/or expectancy:
“We saw many straggling white pines, commonly unsound trees, which had therefore been skipped by the choppers; these were the largest trees we saw; and we occasionally passed a small wood in which this was the prevailing tree; but I did not notice nearly so many of these trees as I can see in a single walk in Concord.”
—Henry David Thoreau (1817–1862)
“I have never worked for fame or praise, and shall not feel their loss as I otherwise would. I have never for a moment lost sight of the humble life I was born to, its small environments, and the consequently little right I had to expect much of myself, and shall have the less to censure, or upbraid myself with for the failures I must see myself make.”
—Clara Barton (1821–1912)
“O, what a noble mind is here o’erthrown!
The courtier’s, soldier’s, scholar’s,eye, tongue, sword,
Th’ expectancy and rose of the fair state,
The glass of fashion and the mold of form,
Th’ observed of all observers, quite, quite down!”
—William Shakespeare (1564–1616)
