IFRS 17: mensuração estocástica do ajuste de risco e evidenciação em notas explicativas

Abstract in Portuguese
O IFRS 17 estabelece novos princípios de reconhecimento, mensuração e evidenciação das informações financeiras de (res)seguradoras. Requerimentos deste novo padrão envolvem a estimação e a evidenciação de fluxos de caixa de cumprimento (FCC), compostos pelo valor presente esperado das obrigações adicionado de um Ajuste de Risco (AR), que incorpora a incerteza sobre sua realização. O objetivo deste trabalho é mensurar o FCC relativo ao passivo de sinistros incorridos e seu respectivo ajuste de risco, utilizando modelagem estocástica (bootstrap) para estimar distribuições de probabilidade empíricas, e value at risk para obter o nível de confiança, com seu expected shortfall associado. Utilizaram-se dados reais de uma seguradora brasileira, compreendendo um histórico de oito anos de sinistros de seguros de automóveis (Casco e Responsabilidade Civil Facultativa). Os resultados mostram que a abordagem proposta traz importantes vantagens como a obtenção direta de medidas de risco de insuficiência de provisão, aspecto relevante para a gestão e para transparência de divulgação em relatórios financeiros. Ademais, quanto maior o nível de correlação entre as carteiras, e quanto maior o nível de confiança almejado, maior será a demanda de capital via AR. Finalmente, propuseram-se elementos chave para o disclosure relacionados ao passivo de sinistros incorridos.

Abstract in English
IFRS 17 establishes new principles for recognizing, measuring and disclosing the financial information of (re)insurers. The requirements of this new standard involves the estimation and disclosure of fulfillment cash flows (FCF), composed of the expected present value of obligations plus a Risk Adjustment (RA), which incorporates uncertainty about their realization. In this study, we aim to measure the FCC related to liabilities for incurred claims and its respective risk adjustment, using stochastic modelling (bootstrap) to estimate empirical probability distributions, and value at risk to obtain the confidence level, with its related expected shortfall. We used a real dataset from a Brazilian insurance company, comprising an eight-year historic of motor insurance claims (Hull and Third Party Liability). The results show that the proposed approach brings important advantages, such as direct obtention of risk measures of insufficient reserves, a relevant aspect for management and disclosure transparency in financial reports. Furthermore, the greater the level of correlation between the portfolios, and the greater the desired confidence level, the greater the demand for capital via RA. Finally, key elements were proposed for disclosure related to liability for incurred claims.
