Based on economists' forecasts and analysis, one$-$year Treasury bill rates and liquidity premiums for the next four years are expected to be as follows:

$1_1{R}_1=0\mathrm{.}42\%$

$E{(}_2{r}_1)=0\mathrm{.}78\%,L_2=0\mathrm{.}07\%$

$E{(}_3{r}_1)=0\mathrm{.}88\%,L_3=0\mathrm{.}11\%$

$E{(}_4{r}_1)=1\mathrm{.}18\%,L_4=0\mathrm{.}12\%$

Calculate the yield to maturity for four years. $($Round your percentage answers to $2$ decimal places. $($e$.$g$.,32\mathrm{.}16))$
