In this paper, we consider an extension of the classical risk model. In this contribution, a tail dependence structure between claim amounts and inter-loss times with a Brownian disturbance is introduced by the Spearman copula in order to evaluate the Gerber-Shiu functions and the loss probabilities associated with this model. We determine integro-differential equations for the Gerber-Shiu function from which expressions for the Laplace transforms of the time to ruin and the deficit to ruin are derived for claim amounts that obey an exponential law.
