This thesis aims to propose a solution for the problem of the estimation of Incurred but not reported (IBNR) reserves from a probabilistic perspective. It is applied the theory of Copulas that allows to consider the dependency, linear or not, among variables: accident year, development year and claim size through a multivariate probability distribution. For this purpose, 2 bivariate copulas are modelled; one copula to estimate the frequency table and the other copula to simulate the claim size by accident. Applying this model is possible to introduce expressions of Expectation, Variance and Confidence Interval. Finally, the results of the proposal model are compared with those of the deterministic method Chain Ladder, a traditional method used by most of insurance companies, showing that the proposal model has much less bias than the Chain Ladder method and furthermore the proposal model overcome the drawbacks of the Chain Ladder method.
