In this study, we deal with the fair pricing of with-profit policies sold in UK. The features of UK with-profit policies are that the credited return is smoothed and is associated with some types of minimum guarantee. In this research, we make use of simulation analysis to compare the efficiency frontier between buying a with-profit policy and investing directly in the market. In addition, we calculate the fair pricing interest rate under different investment strategies and its impact on the insurer's solvency. In this research, we find that when the insurer sets the investment strategy more aggressive, it is more advantage to buy with-profit policies. The effect is more significant for the policies with longer maturity. However, when considering the insolvency risk, the insurer intends to set a lower pricing interest rate. The research findings arc helpful for the local insurance companyfs reference.
