This paper develops the surplus valuation model for the property and liability insurer with the consideration of the random-time insolvency risk and the associated insolvency cost, which is not assumed in most previous studies. Traditional model may overestimate surplus value because early ruin risk and catastrophic risk are not included. The jump models under various distributions, which is commonly encountered by P/L insurer, are also investigated. The catastrophe risk is analyzed under systematic framework. We show that actual surplus value will be much lower if the associated catastrophe risk consists of systematic component. Under certain assumptions, we are able to derive the analytical solutions and the numerical solutions. Our result can be viewed as a potential advance from traditional option-based valuation model.
