Exercise
For a fully discrete 10 -payment whole life insurance of [math]H[/math] on (45), you are given:
(i) Expenses payable at the beginning of each year are as follows:
Expense Type | First Year | Years 2-10 | Years 11+ |
---|---|---|---|
Per policy | 100 | 20 | 10 |
[math]\%[/math] of Premium | [math]105 \%[/math] | [math]5 \%[/math] | [math]0 \%[/math] |
(ii) Mortality follows the Standard Ultimate Life Table
(iii) [math]i=0.05[/math]
(iv) The gross annual premium, calculated using the equivalence principle, is of the form [math]G=g H+f[/math], where [math]g[/math] is the premium rate per 1 of insurance and [math]f[/math] is the per policy fee
Calculate [math]f[/math].

\begin{aligned}
& G \ddot{a}_{45: \overline{10}}=H A_{45}+G+0.05 G \ddot{a}_{45: \overline{10}}+80+10 \ddot{a}_{45}+10 \ddot{a}_{45: 10} \\
& G=\frac{H A_{45}+80+10\left(\ddot{a}_{45}+\ddot{a}_{45: 10 \mid}\right)}{0.95 \ddot{a}_{45: 10}-1} \\
& G=\frac{H A_{45}+80+10(17.8162+8.0751)}{(0.95 \times 8.0751)-1} \\
& G=\frac{A_{45}}{(0.95 \times 8.0751)-1} H+\frac{80+10(17.8162+8.0751)}{(0.95 \times 8.0751)-1} \\
& g=\frac{A_{45}}{(0.95 \times 8.0751)-1} \\
& f=\frac{80+10(17.8162+8.0751)}{(0.95 \times 8.0751)-1}=50.80
\end{aligned}
