指數年金參與率

以下六種:

Ⅰ、點對點法:合約起始時之指數與合約終止時之指數的增加率。

例1.: 假設李先生選擇購買10,000美元之指數年金,契約期間7年、指數連動利率採「點對點法」、參與率100%,當時之S&P 500指數為1,000點。

1. 7年後,契約期間終了之指數若為1,500點
(1) 指數連動利率為50%
 (1,500-1,000)÷1,000=50% (1)
(2) 參與率100%,指數報酬(即實際利率)為50%
 (1)×100%=50% (2)
(3) 李先生可獲之利息為5,000美元
 10,000×(2)=5,000
2. 7年後,契約期間終了之指數若為900點
(1) 指數連動利率為–10%
 (900-1,000)÷1,000=–10%
(2) 由於指數連動利率為負數,李先生可選擇最低保證利率的計息方式,以保費九成、年利率3%複利計算如下:
 10,000×90%=9,000
 9,000×(1+3%)7=11,068
(3) 李先生實際獲得之利息為1,068美元
 11,068-10,000=1,068
 

Ⅱ、高標法:合約起始時之指數與合約期間最高指數之增加率。

1. 7年後,契約期間指數之最高點若為1,600點
(1) 指數連動利率為60%
 (1,600-1,000)÷1,000=60% (1)
(2) 參與率90%,指數報酬(即實際利率)為54%
 (1)×90%=54% (2)
(3) 陳先生可獲之利息為5,400美元
 10,000×(2)=5,400
2. 若購買該指數年金之契約期間股價指數表現不佳,同樣的當契約到期時,陳先生可就「指數報酬」與「最低保證利率」孰者較為有利,擇一計息。

Ⅲ、低標法:合約期間最低股價指數之與合約終止時之指數的增加率。

Ⅳ、年增法:以契約期間各年度年初至年底股價指數之增加率加總而得,若其中股價指數年稱率呈負成長,則該年度之增加率以0計算。

例3.: 假設王先生選擇購買10,000美元之指數年金,契約期間5年、指數連動利率採「年增法」、參與率70%,當時之S&P 500指數為1,000點。

1. 五年契約期間,若每週年之S&P 500指數分別為900點、1,100點、1,200點、1,100點,契約到期時之指數則為1,300點。指數連動利率為49.5%

*當指數下跌,計算出之指數報酬為負數時,給付之下限為0%。
(1) 參與率70%,指數報酬(即實際利率)為34.65%
 (1)×70%=34.65% (2)
(2) 李先生可獲之利息為3,465美元
 10,000×(2)=3,465
2. 若購買該指數年金之契約期間股價指數表現不佳,同樣的當契約到期時,王先生可就「指數報酬」與「最低保證利率」孰者較為有利,擇一計息。

 Ⅴ、多年期增加法:通常是每2~3年計算股價指數的增加率。

Ⅵ、數位法:基於“開\關”原理而設計,當合約期間年度之年增率為正數時則加計一固定報酬率。
