The parameter 0 of the FGM distribution governs the strength of dependence, with a smaller value of 0 corresponding to a less risky situation. For the subexponential case with -1<0=1, a general asymptotic formula for the finite-time ruin probability was derived. However, the derivation there is not valid for the least risky case 0=-1. In this paper, we complete the study by extending it to ?=-1. The new formulas for 0=-1 look very different from, but are intrinsically consistent with, the existing one for -1<0=1, and they offer a quantitative understanding on how significantly the asymptotic ruin probability decreases when ? switches from its normal range to its negative extremumEn: Insurance : mathematics and economics. - Oxford : Elsevier, 1990- = ISSN 0167-6687. - 04/05/2015 Volumen 62 - mayo 2015 I.
