目前國際上已對於保險業的清償能力、會計原理、監理制度及風險管
理等相關領域投入許多的努力。而歐盟國家所發展的Solvency II 即是未來
保險監理制度的主要趨勢。本研究整理相關的文獻以及研究報告書,以歐
盟CEIOPS機構所提出的量化影響研究(QIS)和瑞士FOPI機構的清償能力
測試(SST)為主,簡述Solvency II 的相關內容。
且依據Solvency II 量化的方式以及公平價值的概念,而利用附最低保
證的GMDB與GMMB商品而作範例說明。分別在風險中立測度下,衡量最
適估計(Best Estimate)、風險邊際(Risk Margin)以及清償資本額要求
(SCR)。至於風險邊際,則是使用百分位數法與資金成本法而作比較。
主要研究結果如下:
一、 附保證商品在低利率的經濟環境時,會迫使保險公司計提較多
的資本要求。
二、 利率在固定假設下,所計提的資本額度高於利率為隨機的假
設。主要原因在於本文所選定的利率模型為CIR Model,造成
利率具有回歸到歷史平均水準的特性,也因此讓保單持有人所
擁有的「賣權」成為價外(Out of the Money)選擇權。
三、 資金成本法計提較多負債項目的風險邊際,而減少股東權益項
目的清償資本額的要求。原因在於較能保護保單持有人,讓原
保險公司能夠順利被接管(Take Over)而保障業務的持續性
