Ruin probabilities in the Cram\'er-Lundberg model with temporarily negative capital
, 2019 We study the asymptotics of the ruin probability in the Cram\'er-Lundberg model with a modified notion of ruin. The modification is as follows. If the portfolio becomes negative, the asset is not immediately declared ruined but may survive due to certain
