Putting aside adequate amount of capital and absorbing losses even during recession times are important for financial stability management and for shareholders. There are non-linear dependence and heavily skewed loss distributions in insurance. Copula as risk-aggregation measure is not yet widely used in the insurance sector. Therefore, we are going to study how to choose the most appropriate type of copula for non-life reserve risk, calculate adequate capital by applying value-at-risk at 99.5% which is mandatory in EU market, and select the copula and hypothesis tests to choose the most appropriate copula type for reserve risk. A case study based on actual data will be discussed.

Keywords
VaR, copula approach, insurance economic modelling, internal capital modelling, hypothesis tests, selected copula tests, stability management.
