Grossing-up Factor

A factor used to adjust a base figure to an ultimate one. For example (01) The ratio between the ultimate cost and the accumulated payments at a prior development period, as used in statistical claims projection methods, such as the chain ladder method. (02) The scaling-up of claims experience to allow for the expectation of the occasional very large claim. This is used in experience rating of individual claims experience that has been stripped of any very large claims. It is also sometimes used in motor rating to make adequate allowance for large bodily injury liability claims, stripped out of a basic analysis.

Ground-up Loss

In Reinsurance, the term refers to the gross amount of loss occurring to the reinsured, beginning with the first rupee of los and after the application of deductions required by the reinsurance agreement (which can be several in number) (a) the reinsured’s retention in excess of loss covers, (b) other inuring reinsurance says, such as quota share, surplus share, per risk excess, facultative, or common account coverage, or (c) the uncollectibility of any reinsurance. For example, ground up losses subject to a per risk excess treaty protecting the reinsured’s net retention would equal the net loss beginning with the first rupee after reduction of the gross loss by recoveries from other treaties such as surplus covers and facultative placements, but before the application of the deductible in the per risk excess cover itself.
