The study of the assessments for insurance guaranty funds is another related topic stretched from the study of deposit insurance. Moreover, in order to prevent the impact to whole insurance markets and the insured’s right from the insolvencies of some insurance companies, it becomes an important topic to determine if risk-based premiums should be taken against the behavior of moral hazards. So, the concepts to option pricing are performed to assess the premiums in three different models in the thesis：
1. Basic model － Assets and liabilities of insurance companies are stochastic
2. Jump model － Adding a jump part to liability because of discontinous impact, such as catastrophes.
3. GARCH model － the risk level of insurance companies consists of GARCH properties
Some conclusions are simply listed below, according to numerical results：
1. For the insured of high asset-liability ratio, the positive impact on premiums is significant in jump model and GARCH model；however, for the insured of low asset-liability ratio, the differences of the positive impact on premiums in three models are minor. It still shows the premiums in models close to the reality are higher than traditional model.
2. It is uncertain to decide if the theory premiums are higher or lower than the actual premiums. In fact, it is related to the risk properties of different insured.
