Description: This is the discussion of the paper by J. Alan Lauer that develops the apportionate basis for the immediate payment of claims as an alternative to continuous functions. A new function, the apportionable annuity due, is defined and derived and formulas for net premiums and terminal reserves on the apportionable basis are developed. Then an investigation is made of the relationship of net premiums and terminal reserves on the apportionable basis to the corresponding functions on the continuous functions basis.

Description: This paper analyzed the deficit risk that an insurer assumes when a group insurance contract is subject to a retrospective experience-rating arrangement. In this paper, a method for quantifying the deficit risk and determining explicitly an appropriate risk charge level is developed.
