The Cost-loss model considers one forecast prior to an event, while the Extended cost-loss model considers two forecasts at different times prior to the event. The Extended cost-loss model is an example of a dynamic decision model, and links the cost-loss model to the Bellman equation and Dynamic programming.
In the case when the probability of loss is assumed to be a single number , and is the loss from the event occurring, the familiar form of the Hand formula is recovered. More generally, for continuous outcomes the Hand formula takes form: ∫ Ω L f ( L ) d L > B {\displaystyle \int _{\Omega }Lf(L)dL>B} where Ω {\displaystyle \Omega } is the ...
The lack of a precise definition has resulted in confusion in the industry and lack of any “standards”. In 1999, ASTM E2026 was produced in order to “standardize” the nomenclature for seismic loss estimation, as well as establish some guidelines as to the level of review and qualifications of the reviewer. The document was updated in 2016.
Risk is the lack of certainty about the outcome of making a particular choice. Statistically, the level of downside risk can be calculated as the product of the probability that harm occurs (e.g., that an accident happens) multiplied by the severity of that harm (i.e., the average amount of harm or more conservatively the maximum credible amount of harm).
In many applications, objective functions, including loss functions as a particular case, are determined by the problem formulation. In other situations, the decision maker’s preference must be elicited and represented by a scalar-valued function (called also utility function) in a form suitable for optimization — the problem that Ragnar Frisch has highlighted in his Nobel Prize lecture.

Commercial law (or business law), [1] which is also known by other names such as mercantile law or trade law depending on jurisdiction; is the body of law that applies to the rights, relations, and conduct of persons and organizations engaged in commercial and business activities.

The cost and loss of income caused by legal uncertainty, multiplied by possibility of the individual event or legal environment as a whole. [10] One of the most obvious legal risks of doing business not mentioned in the above definitions is the risk of arrest and prosecution.
