Please use the KMV model equation $11\mathrm{.}2$ and $11\mathrm{.}4$ and the data $($from $2021$ to $2023)$ to calculate market value of the assets $($V$)$ and the volatility of the assets $(\backslash$sigma a$)$ from $2021$ to $2023.$

$E=VN(d_1)-D{e}^{-rT}N(d_2)$

Where : $d_1=\frac{ln(\frac{V}{D})+(r+\frac{1}{2}{}_a^2)T}{{}_a\sqrt[\phantom{2}]{T}},d_2=d_1-{}_a\sqrt[\phantom{2}]{T}$ Volatility of equity $={}_e=\frac{N(d_1)V{}_a}{E}..\backslash$table$[[$Years$,2021$$m$,2022$ $m$,2023$$m$],[$Items$],[$E is the market value of equity,$2,915\mathrm{.}43,1,917\mathrm{.}27,2,581\mathrm{.}20],[$D is the book value of liabilities,$1746\mathrm{.}1,1630\mathrm{.}3,1735\mathrm{.}3,-2-10],[$T is the time horizon,$1,1,1],[$r is the risk free borrowing and lending rate,$1\mathrm{.}19\%,3\mathrm{.}08\%,],[$volatility of equity $(\backslash$sigma e$),1\mathrm{.}00\%,21\mathrm{.}10\%,7\mathrm{.}50\%,-2-10\%],[\backslash$table$[[$N$(.)$isthecu$\backslash$mu lativenormaldistribution$],[$function whose value is calculated at d$1],[$and d$2]],,,]]$
