The goal of the life insurance company is to stabilize the capital because the operation of the life insurance company depends on policyholder’s trust. By the historical data, the net value of the life insurance company has high correlation with the stock market, implying the systematic risk, which can’t be removed by the asset portfolio and has ‘Event trigger’ characteristic. This research is conducted by the internal model approach with the double exponential jump process to model the asset dynamic process. We use a sample retirement insurance to construct the liability side. With asset and liability models, we can find that the probability and the severity when the life insurance company facing the systematic risk. The research shows that: (1) Compared to the B-S model, the double exponential jump process shows higher default probability. (2) Higher leverage, the mean of the stock, risk premium of the liability, and the elasticity of the interest rate on the liability will cause higher default probability and default value.參考文獻 中文部分1. 張士傑,民國96年度。EU Solvency II:整合型態風險管理的保險監理架構。風險與保險雜誌,N0.12,Page2-Page6。2. 張士傑,民國99年度。保險契約之評價與風險管理。臺北縣三重市:前程文化。3. 財團法人保險發展中心,http://www.tii.org.tw/4. 周俊宇、鍾熾昌、高春元、黃偉豪,民國101年度。Jump Diffusion Model。5. 黃雅文、張士傑,民國100年度。《保險業資產配置之決定及其影響》。出版地:財團法人保險安定基金。6. 梁昭銘,民國94年度,保險業資金運用規範之妥適性-以中壽投資開發金衍生之爭議為例。未出版之博(碩)士論文,政治大學,風險管理與保險學系,台北市文山區。7. 梁正德,民國102年度。《國際保險業清償能力制度之研究》。出版地:財團法人保險事業發展中心。8. 蔡政憲,民國94年度。《臺灣保險監理之利率模型系統》。出版地 : 金管會保險局。9. 臺灣經濟新報資料庫,http://www.tej.com.tw/twsite/TEJ%E8%B3%87%E6%96%99%E5%BA%AB/tabid/164/language/zh-TW/Default.aspx10. 臺灣證券交易所,http://www.twse.com.tw/ch/index.php11. 鄭力瑀,民國100年度,監理寬容下保險安定基金公平費率。未出版之碩士論文,政治大學,風險管理與保險學系,台北市文山區。12. 證券櫃檯買賣中心 ,http://www.tpex.org.tw/web/?l=zh-tw13. 連宏銘,民國103年。《2014年保險業國際化菁英人才培訓班出國計畫》。出版地:財團法人保險事業發展中心。英文部分1.
