In this study, VaR (Value-at-Risk) risk measure which is commonly used in financial sector in recent years, are
analyzed by minimizing cedent’s total risk of exposure using Monte Carlo Stochastic optimization method, with
calculating the optimal retention limit in terms of expected and standart deviation premium principles under
the stop loss reinsurance contract for the cedent. Thus, it is revealed that, in the circumstances, when analytic
solution is not achieved, the optimal retention limit can be achieved by Monte Carlo optimization method.
