Résumé : In the classical model of risk theory with the claim sizes arithmetically distributed, we consider the time T of the first crossing between the surplus process and a given (non-necessarily linear) upper barrier. The distribution of T is recognized to be discrete and the related probabilities can be expressed explicitly using a family of Abel-Gontcharoff polynomials when all claims have unit value, or a natural extension of these polynomials in the general case. © 1994.
