They are also useful for determining adequate insurance premiums, when loss experience is used as a rating factor [4] [5] [6] Loss development factors are used in all triangular methods of loss reserving, [7] such as the chain-ladder method.
The chain-ladder or development [1] method is a prominent [2] [3] actuarial loss reserving technique. The chain-ladder method is used in both the property and casualty [1] [4] and health insurance [5] fields. Its intent is to estimate incurred but not reported claims and project ultimate loss amounts. [5]

A common case in literature is to define TVaR and average value at risk as the same measure. [1] Under some formulations, it is only equivalent to expected shortfall when the underlying distribution function is continuous at VaR α ( X ) {\displaystyle \operatorname {VaR} _{\alpha }(X)} , the value at risk of level α {\displaystyle \alpha ...
